It is a control unit that does.

Next, the operation of this embodiment having the above configuration will be described. The main part of the operation of this embodiment is shown in FIG.
It is as shown in the flowchart of FIG.

When the earth leakage breaker 14 is inserted into the commercial power source 13 to set the power source, the hot water washing toilet seat function and the cooling / heating / blower functions can be used. When the user sits on the toilet seat 16, the seating switch 53 is turned on. Cooling / heating selector 74
When "cooling" is selected in, the polarity converter 52 selects the plus side, and when the seating switch 53 is turned on, the water passage electromagnetic valve 40 is opened to supply water to the heat exchanger 19 and the electronic cooling element 18 Power supply is started in the positive direction. When the temperature detected by the fin temperature detector 44 of the fin 20 is within a predetermined temperature range and the temperature detected by the temperature detector 42 of the heat exchanger 19 is within a predetermined temperature range, water supply is performed. And the power supply continues. In this way, the temperature of the endothermic fins 20 gradually decreases, and the cool storage part 55 and other parts store heat.

When the user presses the cooling / heating switch 62, the blower 43 is started to operate, and the wind is sent at a preset air volume to supply the cold air. User selects mode switch 65
When the up switch 63 and the down switch 64 are operated to change the air volume setting, the rotation of the blower 43 is changed to the rotation speed according to the set air volume. Then, the temperature set by the temperature preset volume 73 and the air temperature detector 45
The temperatures detected at are compared and the amount of power supplied to the electronic cooling element 18 is adjusted. When the user operates the mode switch 65 and the up switch 63 or the down switch 64 to change the air temperature setting, the power supply amount is adjusted according to the set temperature. And the outlets 22, 23, 24, 2
Cold air is blown directly from the exposed portions of the user's body from 4 ', 25, and the human body can effectively feel a cold sensation with a small capacity of the electronic cooling element 18.

Further, when the user has opened the toilet lid 17 by the seat switch 53 and is not seated, the user is not allowed to control the cold air supply mode by the electronic cooling element 18 or the air blow mode by the blower 43 only. This prevents the cold air from being unnecessarily supplied or blown when the toilet lid 17 is not opened. When the user presses the cold air switch 62 again to instruct to stop the cold air, the operation of the blower 43 is stopped.

As described above, the cold air can be supplied only when the user selects the cool / heat switch 62, and even when the user is seated on the toilet seat 16 and the seat switch 53 is on, the user is Since the cold and warm air is not supplied unless necessary, useless energy can be prevented from being used.

Unless the user turns on the sitting switch 53, the electric power supply to the electronic cooling element 18 and the water supply to the heat exchanger 19 are continued, and when the cold air switch 62 is pressed again, the setting is followed. It is designed to get the temperature quickly. When the user stands up from the toilet seat 16 and the seating switch 53 is turned off, the power supply to the electronic cooling element 18 and the energization to the solenoid valve 33 are automatically stopped, and the water passage solenoid valve 40 is stopped after a predetermined time. . The reason why the water flow is stopped after a predetermined time is to prevent the temperature rise especially on the heat exchanger 19 side and stop the electronic cooling element 18 after sufficiently cooling it to improve the durability. The reason why the solenoid valve 33 is stopped before the water passage solenoid valve 40 is stopped is to prevent an excessive pressure from being applied to the hot water storage tank 37.

When the user stands up from the toilet seat 16 without pressing the cold air switch 62 again, the blower 43 is stopped, then the electronic cooling element 18, and then the solenoid valve 33 and the water passage solenoid valve 40 after a predetermined time. To stop. Therefore, it is possible to cope with the user's forgetting to stop the cold air switch 62.

When the temperature detected by the fin temperature detector 44 or the temperature detector 42 exceeds the predetermined temperature range, the power supply to the electronic cooling element 18 is stopped and the display 66 displays a message to that effect. After a lapse of a predetermined time, the solenoid valve 33 and the water passage solenoid valve 40 are stopped. When the temperature detected by the fin temperature detector 44 of the heat absorbing fin 20 exceeds the predetermined temperature range, or when the temperature detected by the temperature detector 42 of the heat exchanger 19 exceeds the predetermined temperature range. , Cool / heat selector 74
Selects the "cold" side, and even if the seating switch 53, which is the power supply starting means, is turned on and the cool / warm air switch 62 is instructed to supply cold air, the power supply to the electronic cooling element 18 is forcibly overridden. Stop.

When the temperature detected by the fin temperature detector 44 becomes lower than a predetermined temperature, the electric power supply to the electronic cooling element 18 is stopped, but the operation of the blower 43 and the water flow to the heat exchanger 19 are stopped. While the seating switch 53 is on, heat is dissipated and heat is dissipated. Further, when the temperature detected by the temperature detector 42 of the heat exchanger 19 exceeds a predetermined temperature, the operation of the blower 43 is stopped and water is supplied to the heat exchanger 19 while the seating switch 53 is on. Continue without stopping.

When the user turns on the blower switch 62, the blower 43 is operated at the number of revolutions according to the set air volume,
From the outlets 22, 23, 24 ', 24 ", 25, only the wind directly hits the exposed parts of the user's body.
Therefore, when the user does not require a particularly cold temperature depending on the physical condition, the ambient temperature, and the season, the user can apply only the wind to the exposed part of the body to obtain a cool breeze.

The use of the cold air and the other functions of the hot water washing toilet seat 10 can be combined with the cleaning function. Especially in this case, even if the cold air switch 62 is not pressed, the solenoid valve 3
When 3 is opened, the water flow solenoid valve 40 is opened, and the heat exchanger 1
It is prevented that the amount of water supply is less than the amount of dead water of the water meter, which is generated when the amount of flush water is small due to the waste water being discharged into the toilet 9 through 9. In particular, when cool air is also designated by the cool / heat selector 74, power is also supplied to the electronic cooling element 18 and cold is stored in the heat radiation fin 20.

When the toilet seat 16 is flipped up during the use of men's purses, the toilet seat 16 blows out the air outlets 22, 23, 24 ', 2
Nos. 4 "and 25 are concealed and prevent the urine from splashing into the air outlets even if they bounce off, and prevent the air outlets themselves from becoming dirty and from smelling urine during use.

Next, the main points of the operation during heating will be described.
The operation during heating is described as a flowchart in FIG.

When the "heating" side is selected by the cooling / heating selector 74, the polarity converter 52 selects the minus side. When the user presses the cooling / heating switch 62, the temperature of the fin 20 is low,
When the temperature of the heat exchanger 19 is higher than the predetermined temperature, the electric cooling element 18 and the heater 45 are simultaneously energized. And
The operation of the blower 43 is started, and the air volume and the air temperature are adjusted. The hot air is blown directly from the air outlets 22, 23, 24, 24 ', 25 to the exposed part of the user's body, and the warm air can be effectively supplied to the human body with a small capacity of the electronic cooling element 18 and the heater 45. . In this case, the heater 45 is the electronic cooling element 18
Since it is provided on the wake side, the hot air does not hit the electronic cooling element 18, which is weak against relatively high temperature during heating,
The durability of the electronic cooling element 18 is improved.

When the temperature of the fins 20 is high, it means that the fins 20 have been overheated and the power supply to the electronic cooling element 18 and the heater 45 is stopped. When the temperature of the heat exchanger 19 is low, the temperature on the heat absorption side of the electronic cooling element 18 is low, so it is determined that the temperature on the heat radiation side cannot be raised even if it absorbs heat from water, and the heat exchanger 19 is notified. Do not pass water through. In these cases, display screen 6
6 is displayed.

While the air temperature does not reach the set value, the operation of raising the air temperature is performed. When the air temperature reaches the set value, the power supply amount is adjusted and the set temperature is maintained. When the user turns off the cooling / heating switch 62, or when the user stands up from the toilet seat 16 and turns off the seating switch 53, energization of the heater 45 and the electronic cooling element 18 and operation of the blower 43 are stopped, and heating operation is stopped.

When the operation is stopped, the power supply to the electronic cooling element 18 is first stopped, then the power supply to the heater 45 is stopped, the blower 43 is stopped, the water flow solenoid valve 40 is stopped, and the electronic cooling element 18 is sufficiently cooled. I am considering it so that I can do it.

Further, unlike the case of cooling, the heater 45 has a sufficient capacity during the heating operation, so that the electronic cooling element 18 is energized in advance before the cooling / heating switch 62 is turned on. Absent.

The operation of supplying cold air and warm air and the operation of only blowing air are not described in detail in FIGS. 7 and 8, but the operation is interrupted by operating the switches 61 and 62 and the cooling / heating switch 74 during one operation and the other operation is performed. Can be migrated. Although not described in detail in the flowchart, the air volume for each setting of the setting device is made different between when the cold air is supplied and when the hot air is supplied, as shown in FIG. That is, even at the same set level, the air volume is large during cooling and small during heating. This is because the electronic cooling element 18 cannot have a very large capacity, so that when the cold air is supplied, the amount of air is increased so that it feels colder.

10 and 11 show another embodiment using the electronic cooling element. Electronic cooling elements 91, 9 in the toilet lid 90
2, heat absorbing fins 93, blowers 94 and 95, heat exchanger 9
6, a water supply pipe 97, a drain pipe 98, a duct 100 and the like are provided. Water supply pipe 97, drain pipe 98, power supply line / signal line 1
01 is provided inside the rotary shaft 102 of the toilet lid 90.

The advantage of incorporating the functional portion of the cooling means in the toilet lid 90 is that it effectively utilizes the open space of the toilet lid, and that the duct distance is shorter than the toilet lid due to the nape of the neck, waist, and buttocks, and cool air can be generated. The point is that hot air can be supplied. Also, the heat exchanger 96
In this case as well, since it is water-cooled, it can be installed in a narrow space of the toilet lid 90 in a compact and highly efficient state.

FIG. 12 shows another embodiment of the present invention in which a compressor is used as the main part of the cooling means.

In the toilet seat body 103 above the toilet bowl 9, a warm water washing toilet seat function part 104 and a cooling function part are provided. Water is supplied to the warm water washing toilet seat function unit 104 from the water supply pipe 105 through the water passage electromagnetic valve 106. The main part of the cooling function part is a refrigeration cycle in which a refrigerant circulates through a compressor 107, a cooling coil 108, a capillary tube 109, and an evaporator 110, a blower 111 that blows cool air to the evaporator 110, and a cooling coil 108 from a water supply pipe 105. It is composed of a heat exchanger 112 that is cooled by water supply. Heat exchanger 112
The cooling water is supplied to and stopped by opening and closing the cooling water solenoid valve 113, and the water that has finished cooling is discharged to the trap 114 and the subsequent portions of the toilet bowl 9. Since the heat exchanger 112 is also water-cooled in this case, it can be used in a compact and highly efficient state even when a relatively large cooling capacity such as a compressor is required. Further, the condensed water of the evaporator 110 is also discharged to the trap 114 and the subsequent portions of the toilet bowl 9. The advantage of discharging after the trap 114 is that it is not necessary to generate a discharge sound that is annoying to the user at the time of discharge. The discharge method is
There are a method of directly discharging to the trap 114 of the toilet and a method of discharging to the downstream side of the trap 114.

The hot water washing toilet seat function unit 104 and the cooling function unit are controlled by the control unit 115, and the same setting as in the previous embodiment is performed by the setting device 116 provided outside.
The cool air obtained in the evaporator 110 part is supplied from the toilet lid part, the main body and the toilet seat part toward the exposed part of the human body by the duct 117. The advantage compared with the case of using the electronic cooling element of the system using this compressor is that a relatively large capacity is easily obtained, and the cooling effect is obtained even when the load is somewhat heavy. Also, the drawback is that the compressor 107
This is a point where the generated sound and vibration are rather large. As a countermeasure, there is a method of installing the compressor 107 outside the room other than the toilet room. There is also a method in which the compressor 107 and the cooling coil 108 are installed outside the toilet room and the cooling coil 108 is changed from water cooling to air cooling. Even in these cases, by directly sending cooling air from the toilet lid, the main body, and the toilet seat to the exposed portion of the human body, the human body can be effectively and quickly cooled with a small capacity.

Of course, the refrigeration cycle section using the compressor 107 may be configured as a heat pump for cooling and heating.

FIG. 13 shows another embodiment regarding the heat radiation form of the electronic cooling element or the refrigeration cycle type cooler. In the hot water storage tank 118 for boiling hot water for washing the toilet seat, the water flowing from the inflow part 119 is guided to the lower part of the tank by the throat pipe 120, is diffused over the entire bottom surface by the baffle plate 121, and the water is heated by the heater 122 and heated. Detector 123
When the temperature detected by reaches the set temperature, the heater 122
Is stopped, and is supplied from the hot water outlet pipe 124 to a cleaning nozzle (not shown) according to the setting. As a safety device, the hot water storage tank 118 is provided with a float switch 125 for detecting drought and a high limit switch 126 for directly turning off the power supply to the heater 122 during abnormal heating.

The bottom surface of the hot water storage tank 118 is composed of a metal plate 127, and the electronic cooling element 128 is closely attached to the outside. A heat absorbing fin 129 is provided on the opposite side of the electronic cooling element 128, and the cooling air is directly supplied to the human body by the air blow from the air blower 130. Further, as in the above embodiment, the heat absorption fin 129 is provided with the fin temperature detector 131 and the air temperature detector 132 after the heat absorption fin 129.

The heat radiation during energization of the electronic cooling element 128 is
The waste heat is applied to the water in the hot water tank 118, and the waste heat is used to boil the hot water storage tank to effectively use energy.

If the hot water outlet tank is sufficiently boiled and has reached the set temperature, it is judged by the signal of the temperature detector 123 to open the drainage electromagnetic valve 133, and the baffle plate 1 is opened.
Drain the water under 21 into the toilet bowl. At this time, water reaches the lower part of the baffle plate 121 through the throw and the pipe 120, but the action of the baffle plate 121 absorbs the heat radiation of the electronic cooling element 128 without mixing with the boiling hot water,
It is discharged into the toilet bowl.

Further, the baffle plate 121 prevents the inflow water and the stored hot water from being mixed with each other at the time of supplying the hot water to the washing nozzle of the normal hot water washing toilet seat, and contributes to the improvement of the tank efficiency.

In each of the above embodiments, the toilet seat means is a hot water washing toilet seat, but it may be a heated toilet seat, a toilet bowl integrated hot water washing toilet seat, or the like.

The power source may be a battery power source, a private power source or the like other than the commercial power source, and the DC power may be a switching power source or a transformer type.

Further, as the air blowing means, an air compressor may be used instead of the air blower 43, or a means for sending air by a duct from a separated air blower.

Further, as the switch of the setting device, the cooling / heating switch 62 and the blower switch 61 are used, but a non-touch type switch or a rotary type switch may be used.

In the above embodiment, the water supply means is the water supply 11
Although the method of taking water from the tank is given as an example, a method of pumping water from a low tank or the like may be used.

Further, although the heat exchangers 19, 96, 112 through which water passes are used as the heat exchangers in the above-mentioned embodiment, a form in which water is dropped may be used.

The electronic cooling element 18 may be of various types such as germanium-silicon type, iron-silicon type, zinc-antimony type other than bismuth-tellurium type.

[0099]

As described above, the present invention is based on the fact that the cooling means is used to directly supply cold air or warm air to the human body, and the power supply for supplying power to the cooling means is shared with the toilet seat. It has such an effect.

(1) By blowing out cool air from the toilet lid, the back, neck and waist of the human body can be effectively cooled even if the cooling capacity is small. You can get a feeling. In addition, by using the toilet seat power supply as the power supply for the thermoelectric cooler, it is not necessary to install a special power supply, and the work can be omitted. You can do it.

(2) By blowing out cool air from the toilet seat means, the waist and buttocks of the human body can be effectively cooled even if the cooling capacity is small, and compared with the method of cooling the entire toilet,
You can get a cool feeling quickly with less power. In addition, by using the toilet seat power supply as the power supply for the thermoelectric cooler, it is not necessary to install a special power supply, and the work can be omitted. You can do it.

Further, as compared with the method of blowing cold air from the toilet lid, it is difficult to supply cold air to the neck, but other exposed parts can be effectively cooled, and a mechanism portion is built in the toilet lid or cool air is blown. It is not necessary to guide, and the configuration can be simplified.

(3) By providing the cooling means inside or outside the toilet seat means, the weight of the toilet lid can be reduced, the structure can be simplified, and noise and vibration can be prevented.

(4) By the cooling means also serving as the heating means,
Warm air is also supplied directly to the human body, and a warm feeling can be obtained quickly with a small amount of power, and cold / hot air can be supplied arbitrarily by selecting a setting device.

(5) By changing the polarity of the power supply to the electronic cooling element and blowing cold air or warm air toward the human body from the toilet lid, the human body can be effectively cooled and compared with the method of cooling the entire toilet. However, you can get a cool feeling quickly with less power. In addition, by using the toilet seat power supply as the power supply for the thermoelectric cooler, it is not necessary to install a special power supply, and the work can be omitted. You can do it.

Further, since the electronic cooling element can be used to make a structure that is small and does not generate vibrations or noises, it cannot be avoided from the toilet seat due to vibrations and sounds of the user, especially when the toilet is used, but it is incorporated in the toilet seat. But it can be used without problems.

(6) By blowing cold air or warm air toward the human body from the toilet seat means, the human body can be effectively cooled, and a cold feeling can be obtained quickly with less electric power as compared with the system of cooling the entire toilet.

You can do it.

[0108] Further, since the electronic cooling element is used, it is possible to obtain a small structure which does not generate vibrations or noises. Therefore, when the toilet seat is installed, it cannot be avoided due to vibrations and sounds from the user, but it is installed in the toilet seat. But it can be used without problems.

Further, as compared with the method of blowing cold air from the toilet lid, it is difficult to supply cold air to the neck, but other exposed parts can be effectively cooled, and a mechanism portion is built in the toilet lid or cool air is blown. It is not necessary to guide, and the configuration can be simplified.

(7) By sending a larger amount of air in the cold air than in the hot air, even if the capacity of the electronic cooling element is low, the cold air feeling due to the air compensates for the insufficient capacity and a cool feeling is obtained.

(8) By concealing the air outlet with this toilet seat when the toilet seat is inverted, urine scatters into the air outlet and enters the inside when men's urine is used, and odor of urine is generated when cold or hot air is supplied or blown. Occurrence can be prevented.

(9) The heat exchanger exchanges heat with the water supplied from the water supply pipe of the warm water washing toilet seat, so that heat dissipation and heat absorption can be performed in a small size with high efficiency and without special piping work. .
