Description
BACKGROUND OF THE INVENTION
[0001] (i) Field of the Invention
[0002] This invention relates to a urine-feces separation unit and
a lavatory bowl.
[0003] (ii) Background Art
[0004] The lavatory bowl used for the care etc. is well-recognized
as the one that can be set up for a room. The lavatory bowl for
setting up in a room is known as one with a degradation processing
part to do the biodegradation processing of organic wastes such as
excrements and a toilet paper threw in. (Refer to patent document
1).
[0005] The lavatory bowl of the conventional technology is composed
of the lavatory seat for a user to have a seat and the degradation
processing part to do the biodegradation processing of organic
wastes threw in from the lavatory seat opening (the opening for
feces). The degradation processing part is composed of a processing
tank, sawdust in the processing tank and an agitating blade to
agitate sawdust and organic wastes threw in.
[0006] In the lavatory bowl mentioned above, sawdust and organic
wastes are agitated to activate microorganism efficiently by
rotating the agitating blade. It leads to the biodegradation
processing of organic wastes.
[0007] [patent document 1] Japanese published unexamined
application Publication No. 2001-120460
[0008] There are the following problems in many kinds of lavatory
bowls of the conventional technology including the one that is
disclosed in patent document 1.
[0009] The first problem is a point that the lavatory bowl of the
conventional technology is composed of one container putting urine
and feces in. Decreasing "Smell" becomes important when the
lavatory bowl is set up in a room, and when it puts urine and feces
in the same container, decreasing "Smell" by all means becomes
difficult. Moreover, the problem that doing appropriately the
washing processing etc. becomes difficult when it puts urine and
feces in the same container is caused.
[0010] The second problem is a point that sealing performance of
the container where it puts urine and feces are low in the lavatory
bowl of the conventional technology. It is important to decrease
"Smell" as shown in the above-mentioned not only in a room but
anywhere the lavatory bowl is set up. Nevertheless, it has been a
problem that sealing performance of the container is low in the
lavatory bowl of the conventional technology so far.
[0011] The third problem is a point of not being applicable when
the lavatory bowl of the conventional technology is used "only for
urine". The lavatory bowl of the conventional technology should
keep it open the container for feces even when usually used "only
for urine". Therefore, "Smell" cannot be decreased.
[0012] Then, this invention is the one performed to solve the
problems of the above-mentioned the lavatory bowl of the
conventional technology. Also, it is assumed to be problems for
this invention to offer the urine-feces separation unit that can
separate urine and feces, improve sealing performance of the
container for feces etc., and is applicable to the use only of
urine appropriately.

BRIEF DESCRIPTION OF THE DRAWINGS
[0021] A preferred embodiment of the present invention will be
described hereinafter with reference to the drawings, in which:
[0022] FIG. 1 is a diagrammatic cross-sectional view showing a
lavatory bowl according to the present embodiment;
[0023] FIG. 2 is a diagrammatic view showing main parts of the
lavatory bowl in FIG. 1;
[0024] FIG. 3 is a top plan view of FIG. 2;
[0025] FIG. 4 a diagrammatic view showing main parts of the
lavatory bowl in FIG. 1 with an additional opening and shutting
mechanism of an opening and shutting lid; and
[0026] FIG. 5 is a top plan view of FIG. 4.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0027] To avoid making of the drawing complex, some configurations
are properly omitted from FIG. 1 to FIG. 3. (For instance, the
opening and shutting mechanism of the opening and shutting lid
installed in the main body of the lavatory bowl is omitted. This
mechanism is described later.)
[0028] As shown in these figures, the lavatory bowl (1) of the
illustrative embodiment is composed of an outer casing (10), and a
urine container (20) and a feces container (30) installed in the
outer casing (10), and a main body of the lavatory bowl (11), and a
lavatory seat (40) located above the main body (11) of the lavatory
bowl (1), and a lid part (50) located above the lavatory seat
(40).
[0029] A feces slot (12) is provided at a lower position of the
main body (11) of the lavatory bowl (1) of the illustrative
embodiment. The feces slot (12) has an opening and shutting lid
(60). By driving the opening and shutting lid (60), the feces slot
(12) can be opened and shut.
[0030] A urine guidepath (14) in canaliform pattern is provided in
the outer edge part of the feces slot (12). This urine guidepath
(14) has an inclination to a prescribed angle .theta. to flow the
fluids (urine or washing water, etc.) from backward (11b) to front
(11a) of the main body (11) of the lavatory bowl (1). It is
desirable to set up at 2.degree..about.45.degree. and it is more
preferable to set up at 3.degree..about.10.degree. as a "prescribed
angle .theta."
[0031] Troubles may occur in that the fluids such as urine that
dropped on the opening and shutting lid (60) do not gather easily
or take time to gather to the urine guidepath (14) when this
"Prescribed angle .theta." is smaller than 2.degree.. Moreover,
trouble may occur in that the fluids such as the rinse water flows
fast so that enough effects of the washing cannot be achieved when
the washing processing is done (this washing processing is
described later) when this "Prescribed angle .theta." is larger
than 45.degree.. Therefore, it is desirable that "Prescribed angle
.theta." is about 2.degree..about.45.degree. in the illustrative
embodiment mentioned above as the fluids such as urine and the
rinse water that dropped on the opening and shutting lid (60) can
gather efficiently to the urine guidepath (14).
[0032] A through-hole part (15) is provided on the lowest part of
the urine guidepath (14) where it is located on front (11a) of the
main body (11) of the lavatory bowl (1). This through-hole part
(15) connects one end of a urine accumulation tube (16). The other
end of the urine accumulation tube (16) is placed in a urine
container (20). In the illustrative embodiment, "a urine
accumulation part" by this invention is composed of the urine
guidepath (14) and the urine accumulation tube (16).
[0033] A top surface (the top surface of the opening and shutting
lid (60a)) of the opening and shutting lid (60) to opens and closes
the feces slot (12) has an inclination to a prescribed angle
.theta. as well as the urine guidepath (14). As shown in FIG. 1 and
FIG. 3, a surface of an inner edge part (14a) of the urine
guidepath (14) is coplanar with the top surface of the opening and
shutting lid (60a).
[0034] "The urine-feces separation unit" of this invention in this
illustrative embodiment is composed of the opening and shutting lid
(60) to opens and closes the feces slot (12), and the urine
accumulation part to put urine in, which includes of the urine
guidepath (14) and the urine accumulation tube (16).
[0035] The urine container (20) in the outer casing (10) may adopt
any kinds of configuration for a container, for instance, a closed
container as long as a container has a portion to insert the urine
accumulation tube (16). This means a configuration of the urine
container (20) is not limited to a closed container, and is
acceptable to an open type container if required. Also, the urine
container (20) may be composed with detachable one out of the outer
casing (10) according to the state of accommodation such as urine
in the lavatory bowl (1) of the illustrative embodiment.
[0036] It is composed to be open at top surface of the feces
container (30) in the outer casing (10). The porous material
(sawdust) is put in the feces container (30) to do the
biodegradation processing of organic wastes such as feces threw in
from the feces slot (12) though the illustration of the sawdust is
omitted in FIG. 1 and others. The feces container (30) is composed
with detachable one out of the outer casing (10) in the lavatory
bowl (1) of the illustrative embodiment as well as the urine
container (20).
[0037] For instance, the door part (not shown in the figure) to be
opened and shut can be installed at the side of the outer casing
(10) in the lavatory bowl (1) of the illustrative embodiment, and
the urine container (20) and the feces container (30) can be taken
out outside of the outer casing (10) through this door part.
[0038] The lavatory seat (40) is located above the main body (11)
of the lavatory bowl (1) and can be opened and shut if necessary by
means of hinged connection with the outer casing (10) (not shown in
the figure). Moreover, the lavatory seat (40) has the lavatory seat
opening (41) to be thrown urine and/or feces. When a user sits on
the lavatory seat (40) and excretes urine and/or feces, urine goes
to the urine container (20) through the lavatory seat opening (41)
and the urine accumulation part [the urine guidepath (14) and the
urine accumulation tube (16)], and feces goes to the feces
container (30) through the lavatory seat opening (41) and the feces
slot (12). This lavatory seat (40) also can be used as "Heating
lavatory seat" by using an electric heater or the warm water, etc.
In addition, you may install the warm water washing device near the
lavatory seat (40).
[0039] The lid part (50) is located above the lavatory seat (40)
and the lid part (50) can be opened and shut if necessary by means
of hinged connection with the lavatory seat (40) (not shown in the
figure).
[0040] Next, the opening and shutting mechanism of the opening and
shutting lid (60) using FIG. 4 and FIG. 5 is explained. FIG. 4 is a
diagrammatic view showing main parts of the lavatory bowl with an
additional opening and shutting mechanism of opening and shutting
lid in shown at FIG. 1 etc. FIG. 5 is a top plan view of FIG.
4.
[0041] The lavatory bowl (1) of the illustrative embodiment is
composed to be opened and shut the opening and shutting lid (60) by
using the drive motor (61), which opens and shuts the feces slot
(12) that is located at a lower position of the main body (11) of
the lavatory bowl (1).
[0042] Specifically, the drive motor (61) is installed near the
opening and shutting lid (60), and this drive motor (61) is
electrically connected through the electricity wiring (63) and the
drive switch (62) that is located above the outer casing (10). The
first gear (64) is set at the rotating shaft (around the motor
side) (61A) of the drive motor (61), and the second gear (65) is
set at the rotating shaft (around the lid side) (66) that enables
to rotate the supporting part (60b) of the opening and shutting lid
(60). This first gear (64) and the second gear (65) engage
appropriately.
[0043] When the button (62A) of the drive switch (62) is pushed, an
electric signal from the drive switch (62) is transmitted to the
drive motor (61) through the electricity wiring (63) in the
lavatory bowl (1) of the illustrative embodiment. The rotation
driving force of the drive motor (61) is transmitted to the opening
and shutting lid (60) [the supporting part (60b)] through the
rotating shaft around the motor side (61A), the first gear (64),
the second gear (65), and the rotating shaft around the lid side
(66) and it enables to open and shut properly the opening and
shutting lid (60).
[0044] It is composed so that the direction where the drive motor
(61) is rotated may reverse every time the button (62A) is pushed
in the lavatory bowl (1) of the illustrative embodiment. When the
loading more than preset level acts the drive motor (61), the drive
motor (61) may stop. The loading more than preset level is for
instance, in the case that the opening and shutting lid (60) keeps
closed, or the opening and shutting lid (60) keeps open and reaches
the limit of its open.
[0045] Even if feces etc. are piled up on the opening and shutting
lid (60) with closed the feces slot (12), it is composed that the
sensor (not shown in the figure) of the opening and shutting lid
(60) can detect weight more than a prescribed level and let the
opening and shutting lid (60) open by driving the drive motor (61)
automatically in the lavatory bowl (1) of the illustrative
embodiment mentioned above. It prevents troubles in the opening and
shutting mechanism etc. (to be specific, each gear (64) (65), and
the drive motor (61) etc.).
[0046] The lavatory bowl (1) of the illustrative embodiment is
composed it mentioned above and used by the following embodiment
based on the configuration mentioned above.
[0047] First of all, the case that the lavatory bowl (1) of the
illustrative embodiment is used "only for urine" (Only the urine
excretion) is explained.
[0048] When the lavatory bowl (1) by the illustrative embodiment is
used "only for urine" and either the man or the woman uses it, it
is assumed to keep closed the opening and shutting lid (60) of the
feces slot (12) where it is located at a lower position of the main
body of the lavatory bowl (11) (reference as shown in FIG. 2 etc.).
The lavatory bowl (1) is used for a women to have a seat on the
lavatory seat (40) shown in FIG. 2 etc. and for a men to lift up
the lavatory seat (40) shown in FIG. 2 etc. on the upper side. The
lavatory bowl (1) by the illustrative embodiment is applicable to
either use mode.
[0049] When either the man or the woman uses it, urine comes in
contact with front (11a) and backward (11b) of the main body (11)
of the lavatory bowl (1), the top surface of the opening and
shutting lid (60a), and near the top surface (60a) of the opening
and shutting lid (60). Urine that comes in contact with front (11a)
of the main body (11) of the lavatory bowl (1) flows in the
direction of the urine guidepath (14) from front (11a) (reference
as shown the direction of arrow X1 of FIG. 2 and the one of arrow
Y1 of FIG. 3). Urine that comes in contact with backward (11b) of
the main body (11) of the lavatory bowl (1) flows in the direction
of the urine guidepath (14) from backward (11b) (reference as shown
the direction of arrow X2 of FIG. 2 and the one of arrow Y2 of FIG.
3). The top surface (60a) of the opening and shutting lid (60) has
the same inclination as the urine guidepath (14) and urine that
comes in contact with the top surface of the opening and shutting
lid (60a) flows to the lowest point side (position of the
through-hole part (15) (reference as shown the direction of arrow
X3 of FIG. 2 and the one of arrow Y3 of FIG. 3).
[0050] Even if urine comes in contact with any part of the lavatory
bowl, all urines are led to the urine guidepath (14) by
configuration of the lavatory bowl (1) of the illustrative
embodiment. The urine guidepath (14) has an inclination to a
prescribed angle .theta. from backward (11b) to front (11a) of the
main body (11) of the lavatory bowl (1) and urine put together in
the urine guidepath (14) are led to the through-hole part (15)
where is the lowest point of the urine guidepath (14) along a
prescribed angle .theta. (from backward (11b) to front (11a))
(reference as shown the direction of arrow Y4 and Y5 of FIG.
3).
[0051] The through-hole part (15) has the urine accumulation tube
(16) that connects the urine container (20) and urine is put into
the urine container (20) through the urine guidepath (14), the
through-hole part (15), and the urine accumulation tube (16).
[0052] Next, the case that the lavatory bowl (1) of the
illustrative embodiment is used "only for feces" (Only the feces
excretion) is explained.
[0053] When the lavatory bowl (1) of the illustrative embodiment is
used "only for feces" and either the man or the woman uses it, it
is assumed to use the lavatory bowl (1) for a user to have a seat
on the lavatory seat (40). Before or after sitting on the lavatory
seat (40), a user pushes the button (62A) of the drive switch (62)
to open the opening and shutting lid (60) that keeps closed the
feces slot (12) before the feces excretion.
[0054] When the button (62A) is pushed, an electric signal from the
drive switch (62) is transmitted to the drive motor (61) through
the electricity wiring (63), and the rotation driving force of the
drive motor (61) is transmitted to the opening and shutting lid
(60) (the supporting part (60b)) through the rotating shaft around
the motor side (61A), the first gear (64), the second gear (65),
and the rotating shaft around the lid side (66), and then the
opening and shutting lid (60) (refer to the solid line part in FIG.
4) with closed starts activated to open the opening and shutting
lid (60) to the position where the feces slot (12) opens (refer to
virtual line (chain double-dashed line) part in FIG. 4).
[0055] As a user excretes feces after he/she makes the opening and
shutting lid (60) driven to keep open the feces slot (12) which is
located at a lower position of the main body (11) of the lavatory
bowl (1), feces are put in the feces container (30) through the
lavatory seat opening (41) of the lavatory seat (40) and the feces
slot (12).
[0056] Even if a user excretes urine with sitting on the lavatory
seat (40) in the lavatory bowl (1) by the illustrative embodiment,
urine comes in contact with inner surface of the main body (11) of
the lavatory bowl (1) and flows it there, and then urine is led to
the urine guidepath (14). Even if the opening and shutting lid (60)
is kept open, most urine comes in contact with inner surface of the
main body of the lavatory bowl (11) and is put in the urine
container (20) through the urine guidepath (14)
[0057] As the lavatory bowl (1) of the illustrative embodiment is
composed mentioned above and used, it has the following operations
and effects of the invention based on the embodiment etc.
[0058] The lavatory bowl (1) by the illustrative embodiment is
composed to put urine and feces in a separate container [the urine
container (20) and the feces container (30)], and that enables to
inhibit ammonia generation and decrease the possibility to generate
"Smell (stink)".
[0059] The lavatory bowl (1) by the illustrative embodiment has the
opening and shutting lid (60) to open and shut the feces slot (12)
which is located at a lower position of the main body (11) of the
lavatory bowl (1). When the lavatory bowl (1) by the illustrative
embodiment is unused or used only for urine, the feces slot (12) is
kept closed with the opening and shutting lid (60).
[0060] The lavatory bowl (1) of the illustrative embodiment enables
to decrease effectively smell that is generated from the urine
container (20) and the feces container (30) as the air convection
between internal space of outer casing (10) (space where the urine
container (20) and the feces container (30) are installed) and
upper space of the main body of the lavatory bowl (11) is
eliminated. Also, a high effect can be achieved on the aspect of
good hygiene by eliminating the air convection between an internal
space and external space of the outer casing (10).
[0061] The lavatory bowl (1) of the illustrative embodiment has a
beneficial effect on its urinary use. According to the usage
mentioned above, it is properly applicable to the urinary use,
keeping the sealing performance between the internal space and
external space of the outer casing (10).
[0062] When the lavatory bowl (1) by the illustrative embodiment is
used only for urine, it is used for a woman to have a seat on the
lavatory seat (40) shown in FIG. 2 etc. and for a man to lift up
the lavatory seat (40) shown in FIG. 2 etc. on the upper side. The
lavatory bowl (1) by the illustrative embodiment is appropriately
applicable to either use mode.
[0063] When a woman uses the lavatory bowl (1) only for urine,
urine comes in contact with front (11a) of the main body (11) of
the lavatory bowl (1), backward (11b) of it, or the top surface
(60a) of the opening and shutting lid (60) and near the top surface
(60a) of the opening and shutting lid (60), and then urine is put
in the urine container (20) through the urine guidepath (14). When
a man uses the lavatory bowl (1) only for urine (when he lifts up
the lavatory seat (40) and excretes urine upright), most urine
comes in contact with backward (11b) of the main body of the
lavatory bowl (11) and then is put in the urine container (20)
through the urine guidepath (14).
[0064] When a user, whether a woman or a man, uses the lavatory
bowl (1) by the illustrative embodiment only for urine, urine can
be put in the urine container (20) through the urine accumulation
part [guidepath (14) and the urine accumulation tube (16)] with
closed the feces slot (12) which is located at a lower position of
the main body (11) of the lavatory bowl (1) by the opening and
shutting lid (60).
[0065] Anywhere of inner surface of the main body (11) of the
lavatory bowl (1) is inclined to the urine guidepath (14) which is
composed at the outer edge part of the feces slot (12) in the
lavatory bowl (1) of the illustrative embodiment. Urine comes in
contact with front (11a) of the main body of the lavatory bowl (11)
and flows in the direction of arrow Y1 (refer to FIG. 3). Urine
comes in contact with backward (11b) of the main body of the
lavatory bowl (11) and flows in the direction of arrow Y2 (refer to
FIG. 3). Urine comes in contact with both sides (right and left
side) (11c) of the main body of the lavatory bowl (11) and flows in
the direction of arrow Y6 (refer to FIG. 3). All urine from each
part is put in the urine guidepath (14). Even if urine is excreted
in any part of the lavatory bowl (11) in the lavatory bowl (1) of
the illustrative embodiment, urine can be properly put in the urine
container (20) through the urine accumulation part [guidepath (14)
and the urine accumulation tube (16)].
[0066] As the lavatory bowl (1) by the illustrative embodiment can
appropriately put urine, it enables to prevent effectively urine
from being mixed in the feces container (30) and control ammonia
generation and decrease "Smell".
[0067] The lavatory bowl (1) by the illustrative embodiment based
on a configuration mentioned above is easy to use as a compost
lavatory and the potty-seat type lavatory as the collection ratio
of urine is high. It is because urine can be appropriately
separated and collected, and the generation of "Smell" can be
controlled.
[0068] The lavatory bowl (1) of the illustrative embodiment can be
offered as the lavatory of practical use easily and one of serving
many uses for the user who requests urine-feces separation unit
with high level of certainty of separation for resources recycling
business and other reasons.
[0069] Even if a user excretes urine with sitting on the lavatory
seat (40) in the lavatory bowl (1) of the illustrative embodiment,
urine comes in contact with and flows at inner surface 11a, 11b,
and 11c of the main body (11) of the lavatory bowl (1) and then
urine is led to the urine guidepath (14). Even if the opening and
shutting lid (60) is kept open, most urine comes in contact with
inner surface 11a, 11b, and 11c (mainly front part (11a)) of the
main body of the lavatory bowl (11) and is put in the urine
container (20) through the urine guidepath (14).
[0070] Even if urine is excreted during feces excretion in the
lavatory bowl (1) by the illustrative embodiment, it is possible to
properly put urine and feces in each container after separating
them. Therefore, various effects such as decreases of "Smell"
mentioned above can be achieved.
[0071] As the lavatory bowl (1) of the illustrative embodiment
based on a configuration mentioned above can properly put urine in
the urine container (20) without mixing it in the feces container
(30), it can have smaller sized one. If the lavatory is a
configuration that it puts urine and feces in the same container
(ones of such a configuration are most in the conventional
technology), it needs to have big sized feces container (30) and to
do the washing processing in the feces container (30) and the
disposal of organic waste, etc. frequently. However, it enables to
have small sized feces container (30) and decrease the frequency of
the washing processing etc. in the urine-feces separation unit of
the illustrative embodiment as it can put urine and feces in each
container after separating them as mentioned above. Consequently,
it can reduce the size of its configuration in the lavatory bowl
(1) by the illustrative embodiment.
[0072] As the lavatory bowl (1) of the illustrative embodiment uses
the urine-feces separation unit {the urine accumulation part [the
urine guidepath (14) and the urine accumulation tube (16)] and the
opening and shutting lid (60)}, the main body of the lavatory bowl
(11) can be efficiently washed. Therefore, it becomes possible to
keep the lavatory bowl (1) sanitary at any time.
[0073] The washing processing is done at such as inner surface 11a,
11b, and 11c of the main body (11) of the lavatory bowl (1), the
top surface (60a) of the opening and shutting lid (60), and the
urine guidepath (14) by using the detergent and the rinse water,
etc. with keeping closed the feces slot (12) of the main body (11)
of the lavatory bowl (1) by the opening and shutting lid (60) as
the lavatory bowl (1) is used only for urine. When the washing
processing is done as mentioned above, the fluids such as the
detergents and the rinse water flow into the urine guidepath (14)
from inner surface (front (11a), backward (11b), and both sides
(right and left side) (11c)) of the main body (11) of the lavatory
bowl (1) and the top surface (60a) of the opening and shutting lid
(60) as well as the case of urine. Then the fluids which put in
this urine guidepath (14) are led to the urine container (20)
through the through-hole part (15) and the urine accumulation tube
(16).
[0074] The washing processing can be done sanitary without caring
about the smell because it can be done with keeping closed the
internal space of the outer casing (10) that has the feces
container (30) in the lavatory bowl (1) of the illustrative
embodiment. The urine-feces separation unit being used, all of the
washing processing water etc. can be put in the urine container
(20) without mixing and put it into the feces container (30).
Therefore, the washing processing in the main body of the lavatory
bowl (11) can be done only by detaching the urine container (20)
without detaching the feces container (30). In this case, if the
urine accumulation tube (16) is inserted not in the urine container
(20) but, for instance, the tank for washing or the disposal place
out of the lavatory bowl (1), the washing processing can be done
more easily.
[0075] The urine-feces separation unit that composes the lavatory
bowl (1) of the illustrative embodiment can demonstrate various,
excellent effects mentioned above, and it is a very easy, compact
configuration. The size of the unit itself can be greatly
miniaturized compared with the lavatory of the urine-feces
separation type known so far.
[0076] It is not limited to this illustrative embodiment mentioned
above and it is also possible to make various changes to this
invention when needed within the purpose of this invention and that
is all included within the technical scope of this invention.
[0077] It explained the use of the porous material (sawdust) to do
the biodegradation processing of organic wastes such as feces in
the illustrative embodiment mentioned above, however, the invention
is not limited to this configuration and it is possible the use of,
for instance, plant system materials such as straw, rice chaff, and
palm shell or inorganic materials such as activated charcoal and
zeolite. It can be allowed even if the porous material (sawdust) is
not used in the feces container (30) as appropriate in this
configuration.
[0078] It explained the case that "Urine-feces separation unit"
according to this invention is applied to "Portable type lavatory"
that can be set up for a room, which has the urine container (20)
and the feces container (30) in the lavatory bowl (1) in the
illustrative embodiment mentioned above, however, the invention is
not limited to this configuration. The purpose of the "Urine-feces
separation unit" by this invention is to separate urine and feces,
and it can be any configurations of such as the storage method
(device) and the processing method (device) after urine and service
are separated. Therefore, "Urine-feces separation unit" according
to this invention can be applied to the lavatories of
configurations for instance, that collect excretion such urine and
feces outside of the lavatory bowl (1) and do the processing
excretion in the septic tank outside of the lavatory bowl (1).
[0079] It explained the configuration that has the through-hole
part (15) at the lowest point of the urine guidepath (14) and
connects the urine accumulation tube (16) to the through-hole part
(15) in the illustrative embodiment mentioned above; however, the
invention is not limited to this configuration. It can be allowed
the configuration for instance, that has more than one through-hole
parts at the urine guidepath (14) and connects the urine
accumulation tubes to each through-hole parts and inserts them in
the urine container (20) with gathering and bundling them into one.
Or, it can be allowed the configuration that inserts more than one
through-hole parts in the urine container (20) respectively.
Briefly, it is not limited to the configuration of the only one
through-hole part (15) in the urine guidepath (14), and it can be
allowed the configuration having more than one through-hole parts
if necessary in this invention.
[0080] It explained the case that "Urine accumulation part" is
composed of the urine guidepath (14) and the urine accumulation
tube (16) in the illustrative embodiment mentioned above; however,
the invention is not limited to this configuration. For instance,
"Urine accumulation part" can be composed only of the urine
guidepath (14) if it can put urine directly in the urine container
(20) through the through-hole part (15) in the urine guidepath
(14).
[0081] In the illustrative embodiment mentioned above, it explained
the configuration that makes it open the opening and shutting lid
(60) by driving the drive motor (61) automatically when the opening
and shutting lid (60) with keeping closed detects weight more than
a prescribed level to prevent troubles in the opening and shutting
mechanism of the opening and shutting lid (60) in which case feces
etc. are piled up on the opening and shutting lid (60) that keeps
closed the feces slot (12), however, this invention is not limited
to this configuration. It is possible to adopt any configurations
if the opening and shutting lid (60) has the same
structure-function that make itself open when it detects sediments
more than a prescribed level in weights. It can be allowed a
configuration for instance, that does not engage first gear (64)
and second gear (65) when the opening and shutting lid (60) keeps
closed, which is the configuration that engages first gear (64) and
second gear (65) by signal of the drive switch (62) and that the
opening and shutting lid (60) opens by itself when there are
sediments on it.
[0082] It explained the configuration that opens and shuts the
opening and shutting lid (60) using drive motor (61), first gear
(64) and second gear (65) in the illustrative embodiment mentioned
above, however, this invention is not limited to this configuration
as long as a user can open and shut the opening and shutting lid
(60) on his/her intention. It is possible to adopt any
configurations such as the electric mechanism that is a different
from this illustrative embodiment or the mechanism of the machine
type that combines spring and the rod, etc. or the mechanism of the
hydraulic type.
[0083] It explained the configuration that switching action of the
opening and shutting lid (60) is a vertical movement in the
illustrative embodiment mentioned above, however, this invention is
not limited to this configuration. It can adopt the opening and
shutting mechanism of a horizontal movement such as the slide
type.
[0084] It explained the configuration that the drive switch (62) is
installed on the back of a user sitting on a seat in the
illustrative embodiment mentioned above, however, this invention is
not limited to this configuration, and a position of the drive
switch (62) is changeable accordingly. It can be allowed that a
position of this drive switch (62) is installed in any place for a
user to push easily if necessary.
[0085] It explained the case that the urine-feces separation
mechanism according to this invention is applied to a western-style
lavatory in the illustrative embodiment mentioned above, however,
this invention is not limited to this configuration, and it can be
apply to a Japanese style lavatory as a matter of course. All
various effects of explaining in the illustrative embodiment
mentioned above can be achieved if the urine-feces separation unit
{[the accumulation part the urine guidepath (14) and the urine
accumulation tube (16)] and the opening and shutting lid (60)} by
the illustrative embodiment is applied as a Japanese style lavatory
has the feces slot (12) at the lower position of the main body of
the lavatory bowl as well.
