In the former case, as shown in Fig. 7, a heater 8 is installed in the hot water storage tank 19 to supply water. The cleaning water is heated by the heater 8 to be ejected from the cleaning nozzle as the cleaning hot water 1, and the temperature of the cleaning hot water 1 is adjusted by the temperature sensor 20. It becomes difficult to obtain a suitable temperature at the time of use because the capacity is a target, and when all the hot water for cleaning 1 stored continuously is used up, hot water for cleaning 1 can be obtained again. It has been spent for a long time, is not convenient to use, and further requires a large installation space because the hot water storage tank 19 has a large capacity. In the latter instantaneous heating type, as shown in FIG. 8, the cleaning water is heated from the water supply port 5 into the tank 21 while flowing into the cylindrical heater 8 to heat the cleaning water 1 from the water discharge port 6. Is supplied to the cleaning nozzle, the cleaning water supplied in winter is, for example, about 5 ° C, and to warm it to a comfortable temperature of about 38 to 40 ° C,
The heater capacity must be 1500 W or more, it cannot be used in household outlets, and the heater capacity is limited in this way, so the flow rate can be limited, and a comfortable amount of water cannot be obtained. was there.

[Object of the Invention] The present invention has been made to solve the above problems, and an object of the present invention is to obtain hot water even when continuously used in a hot water tank of a local cleaning device as an instantaneous heating type. In addition, despite the fact that the tank space can be made small and compact, even in winter,
It is possible to obtain warm water for cleaning at a comfortable temperature, and to make it a comfortable temperature, you can wash the local area at the desired temperature and water volume at the time of use without reducing the flow rate, especially inside the tank body. By partitioning the top and bottom with the heater plate, the capacity of the upper partition chamber and the capacity of the lower partition chamber can be easily made different, and the capacity of the lower partition chamber can be determined according to the capacity of the heater. It is to be able to select appropriately.

DISCLOSURE OF THE INVENTION The hot water tank of the local cleaning apparatus of the present invention heats the supplied cleaning water and discharges it as the cleaning hot water 1, and continuously discharges it to the cleaning nozzle 3 extending into the toilet 2. In the hot water tank 4 of the local cleaning apparatus A to be supplied to the above, the inside of the tank body 7 is vertically divided by a heater plate 9 having heaters 8 arranged on both sides, and the water supply port 5 is formed by communicating with the upper partition chamber 10. , A water discharge port 6 is formed in communication with the lower partition chamber 11, and a communication port 15 for connecting the upper and lower partition chambers 10 and 11 is arranged on the side farther than the water supply port 5. Therefore, the above-mentioned object can be achieved by this configuration. That is, when the cleaning water is supplied from the water supply port 5 to the tank body 7 at the time of use, the cleaning water once stays in the hot water storage section 10 as the upper partition chamber and is heated by the heater 8 on one side of the heater plate 9. While being heated and then heated by the heater 8 on the other surface of the heater plate 9, the water channel 11 serving as the lower partition chamber
Since the water is supplied from the water discharge port 6 to the cleaning nozzle 3 through the through hole, and therefore both sides of the heater plate 9 are heated by the heaters 8, continuous use is possible as an instantaneous heating type, and the size can be made compact. Nevertheless, in the winter,
Even if the capacity of the heater 8 is not increased, the warm water for cleaning 1 having a comfortable temperature can be obtained, and in order to obtain a comfortable temperature,
At the time of use, the local area can be washed at a desired temperature and water amount without reducing the flow rate. Particularly, by partitioning the inside of the tank body 7 with the heater plate 9 vertically, the capacity of the upper partition chamber and the lower space can be reduced. The capacity of the partition chamber can be easily changed, the capacity of the lower partition chamber can be determined according to the capacity of the heater, and the heating condition can be suitably selected.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. As shown in FIG. 3, the local cleaning apparatus A is constructed by attaching a cleaning / drying machine 12 to the side of the toilet bowl 2. A nozzle pipe 14 extends from the inside of the washing / drying machine 12 into the toilet bowl 2 through a space between the toilet bowl 2 and the toilet seat 13. The nozzle pipe 14 is formed by bending a cylindrical pipe into an S-shape. The base end portion is attached to the rotation driving unit so that the posture can be swung from the retracted posture to the use posture and the posture can be changed. It is connected to the water discharge port 6 at the lower part of the side wall of the hot water tank 4 built therein, and a cleaning nozzle 3 having a nozzle hole is attached to the tip thereof. The hot water tank 4 has a box shape, and in the embodiment shown in FIG. 1, a water supply port 5 and a water discharge port 6 are formed above and below one side wall. The water supply port 5 communicates with the low tank 16 of the toilet bowl 2 via a water supply pipe 17. Inside the tank body 7 up and down near the spout 6,
Partitioned by heater plates 9 with heaters 8 on both sides,
Hot water storage unit 10 as an upper partition chamber inside the tank body 7.
And a water channel 11 as a partition room below is formed. A communication port 15 is formed in the heater plate 9 from the other side wall of the tank body 7 so that the hot water storage section 10 and the water channel 11 communicate with each other. Therefore, during use, the cleaning water sent from the low tank 16 of the toilet 2 to the water supply port 4 through the water supply pipe 17 once stays in the hot water storage unit 10 and is heated by the heater 8 on the upper surface of the heater plate 9. Then, while being heated by the heater 8 on the lower surface of the heater plate 9 through the communication port 15, the water is supplied from the water discharge port 6 to the cleaning nozzle 3 through the water channel 11. Therefore, for example, the heater 8 on the upper surface of the heater plate 9
The heater 8 on the lower surface is set to about 1000 W, the heater 8 on the lower surface is set to 1000 W, and the heater 8 on the upper surface keeps it at a constant temperature for a long time while not in use. The warm water 1 for washing the hot water storage section 10 is caused to flow into the water channel 11 through the communication port 15 and is further heated by the heater 8 on the lower surface of the heater plate 9 in the water channel 11, so that a comfortable temperature can be obtained even in winter without limiting the flow rate. The hot water for cleaning can be supplied from the spout 6 to the cleaning nozzle 3. In this case, the heater 8 of the heater plate 9 is 1300 W on both upper and lower sides, and 1500 W for household use, so it is preferable to control so that the heater 8 on the lower surface is not energized when the heater 8 on the upper surface is energized. . In the summer, hot water for cleaning can be obtained at a comfortable temperature simply by energizing only the heater 8 on the lower surface. Hot water for washing is jetted from the washing nozzle 3 from the water discharge port 6 of the hot water tank 4 through the nozzle pipe 14 to wash the local area after the toilet. After cleaning the local area, wash dryer 1
The warm air is blown from the warm air outlet 18 connected to 2 through the warm air duct to dry the washed local area. In the embodiment shown in FIG. 4, the tank body 7 is provided with two heater plates 9
To form a water channel 11 as a lower partition chamber that communicates with the hot water storage unit 10 as an upper partition chamber. In the embodiment shown in FIG. 5, the heater plate 9 is curved so that the surface area of the heater 8 is large.
If the heater plate 9 is a ceramic heater, the heater plate 9 can be made thin. Therefore, if one heater 8 is embedded as shown in FIG. 6, heat can be conducted to both surfaces.

[Advantages of the Invention] In the present invention, the inside of the tank body is vertically partitioned by a heater plate having heaters on both sides, and a water supply port is formed in communication with the upper partition chamber to form a lower partition chamber. The water outlet is formed by communicating with each other, and the upper and lower partition chambers are connected to each other on the side farther than the water inlet.Therefore, the water inlet is far from the water inlet and the cold water supplied from the water inlet is Without being short-circuited to the water outlet as it is and injected, the convection of warm water heated in the warm water tank can be effectively used to equalize the warm water temperature in the warm water tank, and in particular, Since the inside of the tank main body is partitioned vertically by the heater plate, the capacity of the upper partition chamber and the capacity of the lower partition chamber can be easily made different, and the capacity of the lower partition chamber is determined according to the capacity of the heater. Yes, the heating conditions can be selected appropriately It is.
