DETAILED DESCRIPTION OF THE INVENTION
[0022] In order that those skilled in the art can further
understand the present invention, a description will be described
in the following in details. However, these descriptions and the
appended drawings are only used to cause those skilled in the art
to understand the objects, features, and characteristics of the
present invention, but not to be used to confine the scope and
spirit of the present invention defined in the appended claims.
[0023] With reference to FIG. 1, the
electronically-frequency-controlled voltage adjustment device 20 of
the present invention is illustrated. The present invention
includes a high voltage transformer 10, and a plurality of voltage
selectors 11 connected to the high voltage transformer 10; a
voltage output port 12 connected to all the voltage selectors 11,
and a temperature control unit 13 connected to all the voltage
selectors 11 and a temperature sensor 14 connected the temperature
control unit 13. The temperature sensor 14 serves to transfer the
temperature of a sensed object to the temperature control unit 13.
The temperature control unit 13 generates different voltages
according to the temperature and the voltages are output from the
voltage output port 12. In the present invention, the voltages of
1000V, 2000V, 3000V and 4000V are used as an example, but other
values between 100V to 5000V are permissible in the present
invention.
[0024] Referring to FIG. 1-1, a part of the feedback circuit is
illustrated. When the temperature is changed, the value of the
temperature sensor 14 will be feedback to the high voltage
transformer 10. The output is adjusted by the setting programmable
parameter. When the load is changed, the voltage selectors 11
selects output voltage to the front high voltage transformer 10 to
control the output of the setting voltage.
[0025] In the prior art, the output voltage is fixed by the ratio
of the first side coil to the secondary side coil, but in the
present invention, when the input voltage is changed due to the
variations of the temperature and load, the output voltage is also
changed according to the predetermined program control logic
without manual operation. The temperature control unit 13 and the
voltage selectors 11 adjust the output voltage according to the
temperature from the temperature sensor 14. Thereby the unfreezing
of food is based on an effective work curve.
[0026] FIG. 2 shows the box of the
electronically-frequency-controlled voltage adjustment device 20
according to the present invention.
[0027] In FIG. 2, in one embodiment of the present invention, one
side of the box of the electronically-frequency-controlled voltage
adjustment device 20 is a first side current meter 21 for measuring
input current, and another side of the box is a secondary side
voltage meter 22 for outputting voltage after changed. The box also
has a switch 23 for determining whether the frequency generator is
used, a fault alarm 24, and a power switch 25.
[0028] FIG. 2 show the bottom plate 30 of the
electronically-frequency-con- trolled voltage adjustment device 20
of the present invention.
[0029] In FIG. 3, the voltage providing unit 31 provides input
voltage. Then a conductive electrode is placed in an insulating
space. The high voltage is conductive to a center of a food to be
processed. The temperature control and adjusting unit 32 transfers
temperature signals to the voltage adjustment unit 33 based on the
variation of the conductor temperature. Then the voltage adjustment
unit 32 selectively adjusts the voltage values of the voltage
providing unit 31. Referring to FIG. 4, the frequency generator 40
has a delaying switch 41, a programmable controller 42, and a
current oscillator 43. When it is necessary to unfreeze quickly,
the frequency generator 40 is actuated by a frequency selector.
Then the delaying switch 41 controls the current oscillator 43
intermittently based on the programmable controller 42 so as to
generate intermittent oscillating current. When it is necessary to
retain the foods in a fresh state, the frequency generator 40 can
be neglected.
[0030] FIG. 5 shows one embodiment of the present invention, where
the electronically-frequency-controlled voltage adjustment device
20 is used to a refrigerator.
[0031] In FIG. 5, the outer sides of two inner wall of the
refrigerator 50 are installed with conductive materials 52 and
inner sides thereof are installed with wind nets 53. A tray of the
refrigerator is installed with conductive nets 54. When the high
voltage will cause that nitrogen generates from air. Since foods
contain water which is a conductor, the whole food will form as
electric carriers. Water molecules move dramatically in high
voltage. The electrons in water molecules will ionize. Electrons in
water molecules will be formed as covalent bonds to suppress the
oxidization of water and generate of harmful materials.
[0032] FIG. 6 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is applied to
a cake freeze 60.
[0033] In FIG. 6, conductive material 61 is placed upon the cake
freezer. Insulating material 63 is adjacent to the conductive
material 62. The foods to be processed are placed upon the
insulating material 63. Similarly, since the function of the high
voltage will make air change so as to generate nitrogen. Since
cakes contain water which is a conductor, the whole food will form
as electric carriers. Water molecules move dramatically in high
voltage. The electrons in water molecules will ionize. Electrons in
water molecules will be formed as covalent bonds to suppress the
oxidization of water and generate of harmful materials.
[0034] FIG. 7 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is applied to
a seafood freezer, it has the same effect as described in FIG.
6.
[0035] FIG. 8 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is applied to
a juicer.
[0036] In FIG. 8, the electronically-frequency-controlled voltage
adjustment device 20 is placed upon a container 80 for agitating
juice. When conductor contacts with water, by the high voltage
effect, since the function of the high voltage will make air change
so as molecule moves dramatically in high voltage. The electrons in
water molecules will ionize. Electrons in water molecules will be
formed as covalent bonds. The water molecules become smaller so
that they can be absorbed easily. This kind of juice can increase
the permeability of germs to assist the excretion of heavy metal or
harmful material from human bodies to the circulation of blood and
increase immunity. Furthermore, high voltage causes water to ionize
as oxide and hydrogen and cause part of oxygen as ozone which is a
strong oxidizing agent so as to have the function of sterilization.
Thereby the increment of oxygen has the effect of increase
immunity. Besides the color of the juicy may retain to a fresh
state. Thereby the juicy can retain with a long period.
[0037] FIG. 9 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is applied to
a refreezing box.
[0038] In FIG. 9, the electronically-frequency-controlled voltage
adjustment device 20 is connected to a web 91 of an unfreezing box
90. The web 90 is isolated with an insulating device 92.
Furthermore, the food 93 on the web 91 has a high voltage. Thereby
the foods to be unfreezed may be worked in an effect area of
unfreezation so as to reduce the unfreezation time period and thus
the food has a preferred quality.
[0039] FIG. 10 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is applied to
an oven.
[0040] In FIG. 10, it is illustrated that the voltage of the
electronically-frequency-controlled voltage adjustment device 20 is
transferred to a web 101 which is insulated from a casing. The
foods on the web have the high voltage. Conventionally, since in
the conventionally oven, foods are roasted at the outer sides. It
is possible that the outer side of the foods are burned black, but
the center portion of the foods are retained in an un-roasted
state. By the present invention, a large amount of electric charges
are accumulated on the surface of food and structure of air is
changed. Oxygen ions are separated and the surface of the food is
coated with nitrogen so as to prevent from infection of germs. Thus
the food is retained in fresh state and foul smell is removed.
[0041] FIG. 11 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is used to an
open type refrigerator.
[0042] In FIG. 11, the open type refrigerator 110 has a conductive
material 111 thereon. The conductive material 111 is connected with
a conductive wire. The insulating material 112 is adjacent to the
conductive material 111. The foods to be processed are placed upon
the conductive material 112. In use of the device, when conductor
contacts with water, by the high voltage effect, since the function
of the high voltage will make air change, molecules move
dramatically in high voltage. The electrons in water molecules will
ionize. Electrons in water molecules will be formed as covalent
bonds. When the high voltage causes that nitrogen generates from
air, since foods contain water which is a conductor, the whole food
will form as electric carriers. Water molecule moves dramatically
in high voltage. The electrons in water molecules will ionize.
Electrons in water molecules will be formed as covalent bonds to
suppress the oxidization of water and generate of harmful materials
so as to retain the food in fresh state.
[0043] FIG. 12 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is applied to
a freezer 120.
[0044] In FIG. 12, a control box is installed at an outer side of
the freezer 120 When a cart formed of conductive material 121 and
insulating wheels 122 enters into the freezer 120, the carts carry
foods to be froze. The high voltage of the control box will be
applied to the foods. Since foods contain water which is a
conductor, the whole food will form as electric carriers. Water
molecule moves dramatically in high voltage. The electrons in water
molecules will ionize. Electrons in water molecules will be formed
as covalent bonds to suppress the oxidization of water and generate
of harmful materials so as to retain the food in fresh state.
[0045] FIG. 13 shows that the electronically-frequency-controlled
voltage adjustment device 20 of the present invention is applied to
a fried machine 130.
[0046] In FIG. 13, the fried machine 130 is installed with an
electronically-frequency-controlled voltage adjustment device 20. A
oil tank 131 is conductive. Foods containing water is placed into
oil. In fried process, heat is uniformly transferred into the food
by induction. Thereby the fried process is speeded and the oil
temperature can be reduced. It is impossible that the center
portion is not heated. Thereby the color of the food is beautiful.
Furthermore, water in food is ionized so that water molecules are
conduced to have higher density. Thus, water is retained in the
fried foods. Since micro current will transfer through the food,
when the food is placed within electric field, it will isolate with
oxygen. The greasy will not oxide and the lifetime of greasy will
prolong. The small particles in the fried machine will precipitate.
The grease will not become worse.
[0047] The present invention is thus described, it will be obvious
that the same may be varied in many ways. Such variations are not
to be regarded as a departure from the spirit and scope of the
present invention, and all such modifications as would be obvious
to one skilled in the art are intended to be included within the
scope of the following claims.
