Further, FIG. 3 is a sectional view showing a molded example of the blower and the hot water storage tank, and FIG. 4 is a perspective view showing the structure of the bottom part of the hot water storage tank 22. Note that solid line arrows indicate the flow of drying air, and broken line arrows indicate the flow of deodorizing air. Furthermore, the dashed-dotted line arrow indicates the water flow within the hot water storage tank.

As shown in FIGS. 1 and 2, the toilet seat device A of the present invention includes a cleaning section a for cleaning private parts, a drying section b for drying the private parts after washing, a deodorizing section C for absorbing odors, and the entire device. It consists of a control section d for proper operation. Here, the cleaning part a includes a hot water storage tank 22 containing a hot water heater 21 for heating hot water, and a nozzle/L for spouting hot water to private parts.
/ (not shown) and a pump 23 that feeds hot water to the nozzle. The drying section is provided with a drying passage 27 that communicates between a drying outlet 25 opened in the toilet bowl 24 and an air supply opening 26 opened outside the toilet bowl 24, and a drying impeller 28 and a drying impeller 28 are provided in the drying passage 27. A drying blower aO consisting of a drying motor 29 to be driven and a drying heater 31 heating the drying air are arranged. The deodorizing section C is provided with a deodorizing path 34 that communicates between an odor intake port 32 opened in the toilet bowl 24 and a deodorizing discharge port 33 opened outside the toilet bowl 24, and a deodorizing impeller 35 and a deodorizing impeller 35 are provided in the deodorizing path 34. A deodorizing blower 37 consisting of a deodorizing motor 36 that drives the deodorizing motor 36 and a deodorizing agent 38 are disposed. Further, below the drying blower 30 and the deodorizing blower 37, the hot water storage tank 22 of the cleaning section a is arranged,
As shown in FIG. 3, the case 39 constituting both the blowers 30 and 37 is divided into an upper case 39a and a lower case 39b on a plane passing through the rotation axis of both motors aO137, and the lower case 39b and the hot water storage tank are divided into upper and lower cases. The upper surface of 22 is integrally molded. In order to control the operation of each part, the control section d has electronic components 40 that generate heat, such as a try book and a power regulator, mounted on a board 41, and other electronic components 40' are mounted on another board 41'. The hot water storage tank 22 is loaded and configured, and the lower surface of the hot water storage tank 22 is closed with a heat sink 42 having a plurality of fins 4z erected and one end extending outside the hot water storage tank 22, and the electronic components 40 that generate heat are closed. Heat sink 4
It is fixed directly to the end of 2.

On the other hand, in the hot water storage tank 22, there is a hot water storage tank 22 at the upper end.
A running water wall 47 is provided to form a water supply port 44 for supplying water from the outside and a water supply channel 46 having a water discharge 1:t45 at the lower end between the wall surface of the hot water storage tank 22, and as shown in FIG. A plurality of water passages 48 are provided above the heat sink 42.
A buckle plate 49 made of a perforated plate is arranged so that the water inlet 50 of the water passage 48 is connected to the water outlet 4 of the water supply channel 46.
I am facing 5th. Note that 51 indicates a heat insulating material disposed between the heat sink 42 and the exterior 43, and 52 indicates a discharge port for discharging hot water from the hot water storage tank 22.

Next, the operation will be explained. During drying operation, drying air is supplied to the air supply port 26 by operating the drying blower 30.
A flow is formed from the air to the drying outlet 25, and the hot air is turned into warm air by the drying heater 31 and is discharged into the toilet bowl 24 through the drying outlet 26, and is used for drying the private parts. Also, during deodorizing operation, by operating the deodorizing blower 37, the air in the toilet bowl 24 is sucked into the deodorizing path 34 through the odor intake port 32, passes through the deodorizing agent 38, and receives the deodorizing effect. The airflow is discharged from the deodorizing outlet 33 to the outside of the toilet bowl 24, and during cleaning operation, the pump 2a is driven to pump hot water in the hot water tank 22 through the outlet 52 into the nozzle.
(not shown) to wash the private parts.

On the other hand, the bottom surface of the hot water storage tank 22 is made up of a heat sink 42, and electronic components 4° that generate heat are fixed to this heat sink 42.
00 Since the heat generation temperature is high, it moves from the electronic component 40 to the hot water via the heat sink 42. That is, electronic components are cooled by a heat sink. Further, a buckle plate 49 made of a perforated plate is provided above the heat sink 42, and a buckle plate 49 is provided above the heat sink 42.
2, by configuring a plurality of water passages 48 with their water inlets 50 facing the water outlet 45 of the water supply channel 46, low-temperature water can flow almost uniformly over the entire surface of the heat sink 42. Therefore, the heat dissipation plate 42 can effectively dissipate heat, and at the same time, the puffful plate 49 suppresses the sudden mixing of low-temperature water supply with the hot water in the hot water storage tank 22, and prevents the sudden temperature rise of the hot water. The decline can be prevented. Further, by disposing the heat insulating material 61 outside the heat sink 42, it is possible to suppress the heat of the hot water from being radiated outward via the heat sink 42.

Further, since the wall surface of the hot water storage tank 22 is heated to a constant temperature by the hot water inside, both motors 29 and 36 are always kept preheated via the lower case 39b.

According to this configuration, since the temperature difference between hot water and electronic components is used and at the same time a part of the hot water storage tank is used as a heat sink,
The configuration of the control section can be made smaller. In addition, water is always supplied during cleaning operation, and the temperature near the heat sink becomes low, which further promotes the cooling effect and at the same time allows the water supply to be preheated, making effective use of heat loss caused by heat generation. . Further, both motors are always preheated through the lower case, and the motors are not overcooled even at low temperatures in winter.

Therefore, the starting load on the motor can be reduced even at low temperatures, and a small-capacity motor can be used. Further, when the drying blower is in operation, when the airflow passes through the inside of the drying blower, the airflow is also preheated via the lower case. Therefore, the amount of heating by the electric heater installed downstream can be reduced. In other words, according to the present invention, it is possible to save space in the control unit and to use the space above the hot water storage tank rationally, as well as to use a small-capacity motor and electric heater. This makes it possible to reduce the size of equipment and save energy at the same time.
