Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] The present invention relates to a cold/hot air radial and
circulatory delivery device, and more particularly to a cold/hot
air radial and circulatory delivery device that can effectively
equalize the indoor temperature.
[0003] 2. Description of Related Art
[0004] In accordance with purposes of industrial manufacture and
improvement of comfort on medical and residential environment, air
conditioners can be classified into heating or cooling
equipment.
[0005] Currently, most pieces of heating equipment use radially
transmitting ceramic heater, which heats its ceramic substrate
through a conductor of high-voltage currents, and in turn transmits
the heat to the medium around through radiation. However, since the
effectiveness of radial heating is inversely proportional to
distance, the longer the distance between the electric heater and
the user is, the worse the effect of heating is. In addition, most
ceramic heaters only have the heating function and are incapable of
cooling.
[0006] Another option is the hot/cold air conditioner, which
pressurizes the refrigerant to condense the air or heats the air by
a heating module to raise/lower the room temperature. However, its
drawback is that the pipe lines must be buried within the wall. It
is not only the construction that costs a lot, the air conditioner
itself is also quite expensive, making it rather inappropriate for
household uses.
[0007] On the other hand, in hotels, office buildings, or senior
housings, there is usually a central air conditioning system to
adjust the temperature of each interior area individually. Its way
of heating is to heat the incoming airflow through the steam
generated by the boiler to increase the temperature. As for the
cooling function, the system cools the air through a cooling tower
by having the wind passing through the cooling water. However, this
kind of equipment is expensive and energy-consuming. Besides, the
central system might also have unnecessary space covered within
(e.g. areas other than bedrooms during sleeping time).
[0008] Prior art such as Taiwan patent application No.100209092
reveals an improvement of electric heater structure, which combines
a electric heater and an electric fan, putting the electric fan in
an appropriate place below the electric heater. The wind of the
electric fan can bring the heated air coming out of the electric
heater to farther yonder to make the indoor space warm and
comfortable. This structure can be applied to all kinds of electric
heaters and also appliances of similar structure. However, the
blowing surface of this structure is much cramped, and it cannot
produce circulating airflows. Therefore, it is difficult to
equalize temperature in each area of the space, leaving people away
from the electric heater still in coldness.
[0009] To summarize, how to effectively use the wind generated by
the fan and equalize the indoor temperature is the subject this
invention orients to delve.
SUMMARY OF THE INVENTION
[0010] Therefore, in view of the defects of the above transmission
cold/heat air device, the present inventor has invented an
effective cold/hot air radial and circulatory delivery device to
equalize the interior temperature.
[0011] The present invention relates to a cold/hot air radial and
circulatory delivery device, comprising a cylindrical shell, which
comprises a base part, an air inlet part, a middle
electromechanical gear, an airflow suction motor, an air outlet
part, and a circuit distribution area; wherein the base part is
located at the lower end of the cylindrical shell, so as to erect
the cylindrical shell on the ground; the middle electromechanical
gear includes a cooling/heating apparatus to heat or cool the
airflow coming in from the air inlet part, and an airflow guiding
plate set on the airflow outlet, wherein the guiding plate is a
cone whose center is concave, making the profile of the guiding
plate form concave arcs surrounding the cone in a V-shape, whereby
when the guiding plate is placed on the cylindrical shell, the
cold/hot air pumped up by the airflow suction motor (or the air
first pumped up by the airflow suction motor which then passes
through the cooling/heating apparatus for cooling/heating) can
smoothly blow forth radially in a wide angle through the curves of
the guiding plate. In accordance with different embodiments of the
present invention, the wide angle of the guiding plate ranges from
about 180 to 360 degrees.
[0012] According to the cold/hot air radial and circulatory
delivery device, the air inlet part under the cylindrical shell is
formed as a circularity, and the air inlet part is set with at
least one filter inside, which prevents foreign objects and insects
from invading while also filtering the dust in the air to purifying
the air.
[0013] According to the cold/hot air radial and circulatory
delivery device, due to the arcs of the guiding plate caused by the
concave center, the heated/cooled airflow can smoothly send forth
radially in a wide angle to all directions from the air outlet
part. With the coordination between the air outlet part and the
suction of the air inlet part below, the surrounding air can
circulate circulatoryly. Besides, because the suction of the
airflow suction motor under the guiding plate sucks air in through
the air inlet part, and the incoming air is in turn cooled/heated
by the cooling/heating apparatus of the middle electromechanical
gear, temperatures of the ambient air can be equalized through the
circulation of the air.
[0014] According to the cold/hot air radial and circulatory
delivery device, the cooling/heating apparatus can be adjusted to
each user's need to be only configured with cooling apparatus and
used as an electric fan in the summer, or to be only configured
with heating apparatus and used as an electric heater in the
winter, or rather to be configured with both the cooling and the
heating apparatus so as to have both the functions of cooling and
heating. When the apparatus functions as a cooling apparatus, it
may include a plurality of cooling tubes and refrigerant is filled
and circulated in the tubes to cool the passing airflow transmitted
toward the air outlet part and had the airflow flow in a wide angle
outward through the guiding plate. When the apparatus functions as
a heating apparatus, it may be a ceramic heater to heat the passing
airflow transmitted toward the air outlet part and had the airflow
flow in a wide angle outward through the guiding plate. When the
apparatus functions as an apparatus of both cooling and heating, it
can be divided into an upper part and a lower part, wherein in the
preferred embodiment the ceramic heater of the apparatus is set in
the upper part while the cooling tubes are set in the lower part.
In the cooling mode, the ceramic heater would cease from operation
and the refrigerant would be filled and made flow in the cooling
tubes for cooling. Likewise, in the heating mode, the cooling
apparatus would cease from operation and only the ceramic heater
would function for heating. The reason for placing the ceramic
heater on the upper part and the cooling tubes on the lower part is
to prevent the hot air that would rise from the lower part if the
ceramic heater is set therein from damaging the cooling tubes. If
the ceramic heater is set beneath the cooling tubes, the hot air
would rise and pass through the cooling tubes, bringing adverse
effects to the cooling tubes and eventually damaging them in the
long run. If the ceramic heater is set above the cooling tubes,
when the ceramic heater is not in operation and only the cooling
tubes are operating, the cooled air coming out of the cooling tubes
would not bring any adverse effects to the ceramic heater as it
passes through; therefore, this is a preferable arrangement. In the
most preferable embodiment of the apparatus of both cooling and
heating, the order of components of the ideal configuration would
be respectively the cooling tubes, the suction motor, and the
ceramic heater from bottom to top. This configuration can prevent
the heated air from damaging the suction motor as it passes through
the suction motor.
[0015] According to the cold/hot air radial and circulatory
delivery device, the inner face of the cylindrical shell may be
further set with an insulation layer between the cylindrical shell
and the cooling/heating apparatus to prevent the cooled/heated air
of the middle electromechanical gear from changing its temperature
owing to the temperature outside the cylindrical shell. Moreover,
the insulation layer can also ensure the exterior covering of the
cylindrical shell of the cold/hot air radial and circulatory
delivery device from the effects of the temperature outside.
[0016] According to the cold/hot air radial and circulatory
delivery device, the circuit distribution area of the shell is set
with a manipulative keyboard, to which a remote controller can also
be attached. With a wireless signal receiver inside the
manipulative keyboard, the cold/hot air radial and circulatory
delivery device can be controlled remotely to perform different
factions.
[0017] To sum up, the airflow of the cold/hot air radial and
circulatory delivery device is sent forth outward in a wide angle
(preferably 360 degrees) and turned slightly upward. With the
coordination of cold/hot circulating airflows and the suction of
the suction motor set beneath the airflow guiding plate of the air
outlet part, the air around can be circulated circulatoryly and the
ambient temperatures can therefore be equalized. In this way, the
drawback of traditional electric fans and electric heaters of
capable of performing only one function can be easily solved.

DETAILED DESCRIPTION OF THE INVENTION
[0023] In the following detailed description, only certain
exemplary embodiments of the present invention are shown and
described by way of illustration. As those skilled in the art would
recognize, the described exemplary embodiments may be modified in
various ways without departing from the spirit or scope of the
present invention. Accordingly, the figures and descriptions are to
be regarded as illustrative in nature rather than restrictive.
[0024] In the following embodiments of the present invention, it
shall be clearly stated in advance that the words "upper" and
"lower" correspond to the upper direction and lower direction in
the figures.
[0025] Referring to FIG. 1, FIG. 1 shows a cross sectional view of
the first embodiment. As the figure shows, the present invention
provides a cold/hot air radial and circulatory delivery device,
comprising a cylindrical shell (10), which comprises a base part
(11), an air inlet part (12), a middle electromechanical gear (13),
an airflow suction motor (20), an air outlet part (14), and a
circuit distribution area (15). The base part (11) is set under the
cylindrical shell (10) so as to erect the cylindrical shell (10) on
the ground. The middle electromechanical gear (13) includes a
cooling/heating apparatus to cool/heat the air coming in from the
air inlet part. An airflow guiding plate (30) is set on the air
outlet part (14); the guiding plate (30) is a cone whose center is
concave, making the profile of the guiding plate form concave arcs
surrounding the cone in a V-shape, whereby when the guiding plate
(30) is placed on the cylindrical shell (10), the cold/hot air
pumped up by the airflow suction motor (20) can smoothly blow forth
radially in an angle of 360 degrees through the curves of the
guiding plate (30).
[0026] Also referring to FIG. 2, the term "guiding plate is a cone
whose center is concave" means that the guiding plate (30) is a
disk whose center is extending toward the suction motor (20). Based
on the structure, the circular frame (311) of the guiding plate
(30) tapers off inward and downward toward the center of the
guiding plate (312).
[0027] The term "lower side of the guiding plate" signifies the
side of the guiding plate that faces the suction motor (20).
[0028] More specifically, the air inlet part (12), the middle
electromechanical gear (13), and the radial air outlet part (14)
are mutually interlinked. The base part (11) is set under the
cylindrical shell (10) so as to erect the cylindrical shell (10) on
a plane (such as the ground or the platform shown in FIG. 1). And
the outer diameter of the base part (11) is longer than the outer
diameter of the cylindrical shell (10), whereby heavy materials can
be put in the shell to stabilize the device and keep it on the
plane without tipping over.
[0029] The suction motor (20) of the present invention is located
between the middle electromechanical gear (13) and the air outlet
part (14) in the cylindrical shell (10), providing a force
(suction) to suck slowly the air around the air inlet part (12)
into the cylindrical shell (10) and making the incoming air pass
through the middle electromechanical gear (13) to be cooled/heated
and transmitted toward the air outlet part (14). The advantage of
this design is that the suction motor (20) is set in the upper
part, so when the airflow passes through the cooling/heating
apparatus, because the amount of incoming air is greater than the
amount of air that passes through the cooling/heating apparatus,
there are less noises generated from the windward side under the
cooling/heating apparatus. The structure and the suction capacity
of the suction motor (20) are not limited in the present invention,
which only exemplifies in the description, but should accord to the
actual requirement of the implementation which those skilled in the
prior art are familiar with. In the present embodiment, the suction
motor (20) comprises a motor (21) and a fan (22), wherein the motor
(21) leads the fan (22) to rotate and thereby sucks the air around
into the cylindrical shell (10).
[0030] The cooling/heating apparatus (not shown in the figure) is
set in the middle electromechanical gear (13) of the cylindrical
shell (10). The apparatus may include a plurality of cooling tubes
and/or a ceramic heater which spread around the electromechanical
gear (13) in a certain density to cool/heat the air that passes
through the tubes/ceramic heater and have it transmitted to the
radial air outlet part (14) above. As for the operation mechanism
of the cooling/heating apparatus, it is not limited in the present
invention. As an example, when the apparatus is functioning as a
cooling apparatus, refrigerant is filled and made flow in the tubes
to cool the passing airflow and transmit it to the air outlet part
(14) which in turn sends the airflow forth outward and upward
through the guiding plate (30) in an angle of 360 degrees. When the
apparatus is functioning as a heating apparatus, the ceramic heater
heats the passing airflow and transmit it to the air outlet part
(14) to blow outward through the guiding plate (30) in an angle of
360 degrees. When the apparatus functions as an apparatus of both
cooling and heating, the apparatus can be divided into an upper
part and a lower part, wherein the upper part is the ceramic heater
and the lower part are the cooling tubes. In the cooling mode, the
ceramic heater would cease from operation and the refrigerant would
be filled and made flow in the cooling tubes for cooling. Likewise,
in the heating mode, the cooling apparatus would cease from
operation and only the ceramic heater would function for
heating.
[0031] Besides, there is a suction motor (20) installed between the
middle electromechanical gear (13) and the air outlet part (14) in
the cylindrical shell (10) to suck the air into the cylindrical
shell (10) through the air inlet part (12). To make the air
smoothly flow into the cylindrical shell (10) through the air inlet
part (12), the air inlet part (12) is circular wherein a filter can
be set inside to prevent foreign objects and insects from invading
while also filtering the dust in the air, purifying the air sucked
in by the cold/hot air radial and circulatory delivery device and
then sending forth clean air through the air outlet part.
[0032] In addition, in the cold/hot air radial and circulatory
delivery device of the present invention, an insulation layer (40)
can be further set within the cylindrical shell (10) so that the
cooled/heated air of the middle electromechanical gear (13) would
not change its temperature due to heat conduction of circulating
airflows when it reaches the air outlet part (14). Moreover, the
insulation layer (40) can also ensure the cylindrical shell (10) of
the cold/hot air radial and circulatory delivery device from
hurting users due to extremely high/low temperature.
[0033] The circuit distribution area (15) is set on the top of the
shell of the present invention, wherein a removable manipulative
keyboard (unshown in the figure) can be set. A wireless signal
transmitter can be installed inside the manipulative keyboard while
a wireless signal receiver is set within the circuit distribution
area (15). In this way, when the manipulative keyboard is installed
in the circuit distribution area (15), users can manually input
operating instructions like turning on, turning off, airflow
adjusting, switching to cooling or heating mode, and timing to have
the apparatus perform different functions. And when the
manipulative keyboard is removed from the circuit distribution area
(15), users can remotely control the functions through the wireless
signal transmitter inside the manipulative keyboard that transmits
signals to the wireless signal receiver in the circuit distribution
area (15).
[0034] In actual operation, first, the user has to turn on the
apparatus through the manipulative keyboard to start the suction
motor (20) working, which then sucks the air around the cylindrical
shell (10) in through the air inlet part (12) and has it pass
through the cooling/heating apparatus (cooling tubes/ceramic
heater) of the middle electromechanical gear (13) to be
cooled/heated. Then, as the suction motor (20) keeps operating, the
cooled/heated air would be delivered to the air outlet part (14)
and pass through the guiding plate (30) set in the area, blowing
outward through the arcs of the circular frame of the guiding plate
that can guide airflows to 360 degrees and becoming a radial
airflow. With the circulating currents generated by the continual
suction of air through the air inlet part (12) set in the lower
part of the device, the cooling/heating of air through the middle
electromechanical gear (13), and the blowing forth of the
cooled/heated air through the guiding plate (30) of the air outlet
part (14) in 360 degrees, the ambient temperature can be easily
equalized, which effectively resolve the problem of traditional
electric fans and electric heaters as theirs effects being too
partial and too narrow. Above is the first embodiment of the
present invention, and because its guiding plate (30) sends the
cooled/heated air outward in 360 degrees, it is better to be put
near the center of a space.
[0035] Please refer to FIG. 3 and FIG. 5, which show respectively a
cross sectional view and a schematic diagram of the guiding plate
of the second embodiment. As the figures show, the differences
between the first and the second embodiment are the designs of the
guiding plate (53), the air outlet part (52), and the air inlet
part (51) as well as the placement of the middle electromechanical
gear (55); the other parts that are identical would be spared of
repeating here. Referring to FIG. 3, in the present embodiment, the
air inlet part (51) is set exactly under the air outlet part (52),
and the opening angle of the air inlet part (51) and the air outlet
part (52) are exactly the same so as to correspond with each other
in the circulation of currents. In view of the fact that all noises
of wind shear are generated from the windward side (including the
windward side of both the electric fan and the guiding plate), to
increase the wind pressure of outputting wind while simultaneously
decreasing noises of the windward side, it is better to have the
area of the air inlet part (51) larger than the area of air outlet
part (52). More specifically, when the area of air inlet part (51)
is one and a half time larger than the area of air input (52), the
effect will be most significant.
[0036] In the second embodiment, in order to equalize the intensity
of wind, to avoid the problem of having the airflow concentrated
solely frontward, and to coordinate with the types of apparatuses
that can be set at borders, the airflow only blow outward to the
front, the left and the right in 180 degrees. As shown in FIG. 4
and FIG. 5, the V-shape of the present invention includes a
windward side (531) for receiving the pumped cold/hot air from the
suction motor and an air outlet part (52) set beside the windward
side (531). To guide the airflow to both sides of the air outlet
part (14), there are two main wind boards (532) extending from the
center of the windward side (531) toward the two sides of the air
outlet part (52) respectively, and a minor wind board (534) is set
on the windward side (531) opposite to the air outlet part (52).
The main wind boards (531) and the windward side (531) collectively
form a first guiding trail (536) that channels the cold/hot air
downward to the air outlet part (52) and makes the air blow outward
to the front. On the other hand, the minor wind board (534) and the
windward side (531) collectively form a second guiding trail (537)
that channels the cold/hot air downward to the air outlet part (14)
and makes the air blow outward to both sides of the air outlet part
(52). To reduce the noises of wind shear and to avoid the
turbulences generated from the air resistance, the main wind board
(532) has an arc surface (533) that guides cold/hot air to abate
the friction between the airflow and the surface of main wind
boards (532). Likewise, the minor wind board (534) also has an arc
surface (535) to abate the friction among the pumped cold/hot air,
the windward surface (531), and the minor wind board (534),
reducing the noises of wind shear as well as avoiding the
turbulences of airflow by reducing the air resistance.
[0037] Moreover, to prevent the heat radiation and hot wind
generated by the heating device of the electromechanical apparatus
(55) from hindering the operation of the suction motor (54), the
middle electromechanical gear (55) is set above the suction motor
(54) in the present embodiment. When the air flows in, it would
first pass through the suction motor (54) by whose guidance it
later turns upward and passes through the middle electromechanical
gear (55) to be heated, after which it is then sent forth through
the guiding plate (53). This structure can prevent the suction
motor (54) from being damaged by high temperature.
[0038] While the present invention has been elaborated by
exemplifying certain preferred embodiments, it is not to be limited
to the disclosed embodiments. On the contrary, it is intended to
cover various modifications and equivalent arrangements included
within the spirit and scope of the appended claims and equivalents
thereof.
