DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a specific embodiment of a toilet air conditioner according to the present invention will be described in detail with reference to the drawings.

(Embodiment 1) FIG. 1 is a transparent perspective view showing the configuration of the above-mentioned toilet air conditioner. This toilet air conditioner is provided with a Peltier unit 2 as a heat exchanger in a substantially rectangular parallelepiped casing 1. The Peltier unit 2 has a Peltier module sandwiched between a use-side heat sink 18 and a heat-dissipation-side heat sink 19 in the same manner as in the above-described conventional example.
Each of 9 functions as a heat absorber or a radiator. Each of the heat sinks 18 and 19 is constituted by a plurality of plate fins arranged side by side so as to face each other and standing substantially vertically on a flat base plate.

The casing 1 is provided with an exhaust port 5 described below at a lower portion of the left side face 8, and an intake port 3 on a right side face opposite to the left side face 8. Then, the Peltier unit 2 is connected to the intake port 3.
Is formed. Further, the Peltier unit 2 is arranged such that the heat-dissipation-side heat sink 19 is located on the front surface 9 side of the casing 1 and the utilization-side heat sink 18 is located on the rear side of the casing 1. Further, the plate fins of the Peltier unit 2 are arranged so that the fin surfaces thereof follow the airflow flowing through the intake passage 23 from the intake port 3 toward the Peltier unit 2.

Further, an air supply passage 21 is formed substantially horizontally so as to be connected to the use side heat sink 18. An outlet fan 12 driven by a fan motor 11 is provided on the outlet side of the air supply passage 21. Further, an outlet cylinder 6 having an outlet 4 is formed to project obliquely upward to the front of the casing 1 so as to communicate with the outlet side. On the other hand, the exhaust passage 22 is formed so as to be slightly obliquely downward so as to be connected to the heat-dissipating heat sink 19. An exhaust fan 14 driven by a fan motor 13 is provided on the outlet side of the exhaust passage 22. The outlet 5 communicates with the outlet.
Is provided.

Next, the operation of the toilet air conditioner will be described. First, this toilet air conditioner is installed with the front surface 9 of the casing 1 facing the toilet user so that the outlet 4 faces the toilet user. In summer or the like, the Peltier module is energized in a predetermined direction, so that the use side heat sink 18 functions as a heat sink and the heat discharge side heat sink 19 functions as a radiator. Then, the blowing fan 12 and the exhaust fan 13 are further driven.
The blowing amount of No. 3 is about twice the blowing amount of the blowing fan 12.

As described above, the air RA in the toilet is sucked from the intake port 3 into the intake passage 23 and flows toward the Peltier unit 2. That is, the intake port 3
Means that an intake mechanism is constituted by the intake passage 23 communicating with the intake passage 23. And use side heat sink 18
The temperature-controlled air CA cooled in the above is blown out from the outlet 4 through the air supply passage 21. That is, an air supply mechanism is constituted by the air supply passage 21, the blower fan 12, and the fan motor 11 connected to the air outlet 4.
At this time, since the outlet 4 faces the direction of the toilet user, the temperature-controlled air CA is directly blown to the toilet user. On the other hand, the exhaust EA heated by the heat-dissipating heat sink 19 is exhausted from the exhaust port 5 through the exhaust passage 22. That is, the exhaust mechanism is configured by the exhaust passage 22, the exhaust fan 14, and the fan motor 15 connected to the exhaust port 5. Since the exhaust port 5 is provided on the side surface 8 of the casing 1, the exhaust EA
Will be discharged in directions other than toilet users.

On the other hand, in winter or the like, power is supplied to the Peltier module in a direction opposite to the above. Then, the use side heat sink 18 functions as a radiator, and the heat discharge side heat sink 19 functions as a heat sink. Therefore, contrary to the above,
The temperature-controlled air CA heated by the use-side heat sink 18 is blown out from the outlet 4 toward the toilet user, and the exhaust EA provided with the cool heat by the exhaust heat-side heat sink 19 is discharged to the side from the exhaust port 5. You. In this case, the blowing amount of the blowing fan 12 is set to be about twice the blowing amount of the exhaust fan 13.

By the way, the space in the toilet is narrow, and the location of the toilet user is almost constant in the toilet. Therefore, by blowing out the temperature-controlled air CA from the fixed outlet 4 in a fixed direction as described above, the temperature-controlled air CA can always be blown directly to the toilet user. Therefore, even if the exhaust air EA is blown out into the toilet and the entire toilet cannot be air-conditioned, it is possible to surely improve the comfort that the toilet user feels. That is, the exhaust EA can be discharged into the toilet without impairing the use comfort. Therefore, it is not necessary to provide a special heat-dissipating structure at the time of installation, and the installation can be performed very easily.

Since the Peltier unit 2 is used as a heat exchanger, the size of the equipment can be reduced. The two ventilation fans 12 and 14 adjust the ventilation amount on the usage-side heat sink 18 side and the ventilation amount on the heat-dissipation side heat sink 19 so that the ventilation amount on the heat radiation side is about twice the ventilation amount on the heat absorption side. I have to. When the Peltier unit 2 is used, the amount of heat generated by the Peltier module is also radiated in addition to the amount of heat exchanged. However, by setting the ventilation amount as described above, reliable exhaustion can be performed.
Therefore, the heat exchange efficiency of the Peltier unit 2 can be further improved.

FIG. 2 is a transparent side view showing a modification of the toilet air conditioner. This toilet air conditioner is different from the above described one in that an exhaust duct 17 is provided in the exhaust port 5 and the exhaust passage 22 and the other room 32 are provided by the exhaust duct 17.
It is a point that communicates with. By doing so, the exhaust E
Since A is discharged out of the toilet 30, the temperature of the entire toilet 30 can be controlled. In this case, if the exhaust gas is discharged to a corridor or the like, the comfort of use by other residents is not impaired by the temperature or odor of the exhaust gas EA.

FIG. 3 is a transparent side view showing another modification of the toilet air conditioner. This toilet air conditioner is different from the above in that an exhaust duct 17 is provided in the exhaust port 5 and the exhaust duct 17 connects the exhaust passage 22 and the lower part of the floor 31. In this way, the exhaust EA is exhausted to the outside of the living space, so that it is possible to control the temperature of the entire toilet 30 while reliably avoiding deterioration in the comfort of use by other residents. Further, the exhaust air EA may be discharged outside the room through a wall or the like of the house instead of below the floor 31.

(Embodiment 2) FIG. 4 is a transparent perspective view showing a toilet air conditioner of Embodiment 2. This toilet air conditioner is also provided with a Peltier unit 2 as a heat exchanger in a substantially rectangular parallelepiped casing 1. The configuration of the Peltier unit 2 is the same as that of the first embodiment. The casing 1 is provided with an intake port 3 at a lower portion of a front surface 9 thereof. An intake passage 23 extending to the Peltier unit 2 is formed so as to be continuous with the intake port 3.

The Peltier unit 2 includes a casing 1
The heat-dissipating heat sink 19 is located on the back side of the housing 1, and the use-side heat sink 18 is located on the front surface 9 side of the casing 1. And this use side heat sink 18
The air supply passage 21 is formed to be substantially horizontal so as to be connected to. An outlet tube 6 communicating with the outlet side and having an outlet 4 opened is protruded forward of the casing 1. On the other hand, an exhaust passage 22 is formed substantially horizontally so as to be continuous with the heat-dissipating heat sink 19. The casing 1 is connected to the outlet side of the exhaust passage 22.
The exhaust port 5 is formed in the back of the. Further, a baffle plate (air volume ratio adjusting mechanism) 7 is provided between the air supply channel 21 and the exhaust channel 22 for adjusting the ratio of the air volume of the air channel 21 to the air volume of the exhaust channel 22. .

Next, the operation of the toilet air conditioner will be described. First, the toilet air conditioner is also installed with the front surface 9 of the casing 1 facing the toilet user so that the outlet 4 faces the toilet user. In summer or the like, the Peltier module is energized in a predetermined direction, so that the use side heat sink 18 functions as a heat sink and the heat discharge side heat sink 19 functions as a radiator. Further, the pressure-feeding fan 16 is further driven, and the baffle plate 7 causes the amount of air flow in the exhaust passage 22 to be about twice the amount of air flow in the air supply passage 21. In this way, the toilet air RA is drawn into the intake passage 23 from the intake port 3 and flows toward the Peltier unit 2. That is, the intake mechanism is constituted by the intake passage 23 communicating with the intake port 3, the pressure-feed fan 16, and the fan motor 15. The temperature-controlled air CA cooled by the use side heat sink 18
Is blown out of the outlet 4 through the air supply passage 21.
That is, the air supply mechanism is constituted by the air supply passage 21 connected to the outlet 4. At this time, since the outlet 4 faces the direction of the toilet user, the temperature-controlled air CA is directly blown to the toilet user. on the other hand,
Exhaust air EA heated by the exhaust heat sink 19
Is discharged from the exhaust port 5 through the exhaust passage 22. That is, the exhaust mechanism is constituted by the exhaust passage 22 connected to the exhaust port 5. Since the exhaust port 5 is provided on the back of the casing 1, the exhaust EA is exhausted in a direction other than the toilet user.

On the other hand, in winter or the like, power is supplied to the Peltier module in the opposite direction to that described above. Then, the use side heat sink 18 functions as a radiator, and the heat discharge side heat sink 19 functions as a heat sink. Therefore, contrary to the above,
The temperature-controlled air CA heated by the use-side heat sink 18 is blown out from the outlet 4 toward the toilet user, and the exhaust EA provided with the cool heat by the exhaust-side heat sink 19 is exhausted backward from the exhaust port 5. . In this case, the baffle plate 7
As a result, the amount of air flow in the air supply passage 21 is set to be about twice the amount of air flow in the exhaust passage 22.

In the above-mentioned toilet air conditioner, as in the first embodiment, the temperature-controlled air CA is always blown directly from the outlet 4 to the toilet user by blowing the temperature-controlled air CA in a fixed direction. Can blow out. Therefore, even if the exhaust air EA is blown out into the toilet and the air conditioning of the entire toilet cannot be performed, the comfort of the toilet user can be surely improved. That is, the exhaust EA can be discharged into the toilet without impairing the use comfort. Therefore, it is not necessary to provide a special heat-dissipating structure that penetrates the inside and outside of the toilet at the time of installation, and can be installed very easily. Moreover, since only a single fan 16 is provided, the configuration of the device is extremely simple. Therefore, the cost of the device itself can be further reduced.

Since the Peltier unit 2 is used as a heat exchanger, the size of the equipment can be reduced. The baffle plate 7 adjusts the amount of ventilation on the use side heat sink 18 side and the amount of ventilation on the heat discharge side heat sink 19 so that the amount of ventilation on the heat radiation side is about twice as large as the amount of ventilation on the heat absorption side. Therefore, in the same manner as in the first embodiment, the Peltier module is reliably exhausted and the Peltier unit 2 is discharged.
Can further improve the heat exchange efficiency.

FIG. 5 shows a modification of the above-mentioned toilet air conditioner, which is adapted to be mounted on a wall or the like in the toilet. In this toilet air conditioner, an intake port 3 is provided in an upper portion of a front surface 9 of a casing 1. An intake passage 23 leading to the Peltier unit 2 is formed so as to be continuous with the intake port 3, and a pressure feed fan 16 driven by a fan motor 15 is provided at the entrance side of the intake passage 23. And the intake passage 23
Is formed so as to extend downward and reach the Peltier unit 2 located at the center of the casing 1. An air supply passage 21 is formed downward so as to be continuous with the use side heat sink 18. A blow-out projection 10 communicating with the outlet side of the air supply passage 21 and opening the horizontally long blow-out port 4 is provided to project obliquely upward and forward of the casing 1. On the other hand, the exhaust passage 22 is formed so as to face downward so as to be connected to the heat-dissipating heat sink 19. And it communicates with the outlet side of this exhaust passage 22,
Exhaust ports 5, 5 are formed on both side surfaces 8 of the casing 1, respectively. Further, similarly to the above, the baffle plate 7 is provided between the air supply passage 21 and the exhaust passage 22.

In this toilet air conditioner, though the directions of flow of the air RA inside the toilet, the temperature-controlled air CA, and the exhaust air EA are different, the same operation as described above is performed, and the same effect can be obtained. Therefore, it is possible to obtain a wall-mounted toilet air conditioner which is easy to install and has a compact configuration.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be implemented with various modifications within the scope of the present invention. In the toilet air conditioner of the second embodiment, the exhaust EA is exhausted into the toilet. However, as a modification of the first embodiment, as shown in FIGS. Exhaust E indoors or under the floor
A may be released. In this manner, the temperature of the entire toilet can be controlled as in the case of the first embodiment. In each of the toilet air conditioners, the air in the toilet is sucked through the air inlet 3. However, especially in a toilet air conditioner that discharges exhaust EA into the toilet, the temperature of the entire toilet is not adjusted, so that air outside the toilet may be sucked through the air inlet 3. In this way, fresh air can be introduced into the toilet to further improve the use comfort.

In this specification, the thermoelectric semiconductor itself is called a Peltier element, a structure in which the Peltier elements are arranged and sandwiched between both sides by a ceramic plate is called a Peltier module, and the Peltier module and the heat sink 18 , 19 are referred to as a Peltier unit 2.
