Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a sanitary washing device that is mainly attached to a toilet bowl and performs washing by spraying hot water onto a local area of the human body.

[Prior art and its problems]

Conventionally, this type of cleaning device has been configured to include a hot water tank that receives water from a water supply source such as a pump, and to directly jet hot water heated to an appropriate temperature within the tank from a fountain nozzle. However, the capacity and heating ability of hot water tanks are naturally limited, and if continuous use is possible or a large flow of water is required, a fairly large tank is required. In addition, the temperature of the hot water used for washing is controlled by on/off control of a heater installed in the hot water tank, which has extremely poor responsiveness, making it difficult to adjust the water temperature while using it to obtain the water temperature desired by the user. It was hot.

[Means for solving problems]

This invention bypasses the water supply channel from a water supply source such as a pump to the hot water tank, and is located at the mixing channel that connects to the hot water supply channel from the hot water tank to the fountain nozzle, and at the connection between the mixing channel and the hot water channel. The above problem was solved by providing a mixing device that mixes hot water from the hot water supply path and water from the mixing channel to provide cleaning water at an appropriate temperature, and jets out the mixed water from the mixing device. It is something.

〔Example〕

A detailed explanation will be given below based on the embodiments shown in the figures.

Figure 1 is an external view showing the usage state of this embodiment.
1 is a toilet bowl, 2 is a toilet seat placed on the toilet bowl, 3 is a low tank attached to the toilet bowl 1, and 4 is a cleaning device main body according to the present invention. This cleaning device main body 4 is fixed to the toilet bowl 1 and receives water supply via a hose 6 from a pump 5 disposed in a low tank 3.

FIG. 2 is an explanatory diagram of the structure of the main body 4, in which the exterior body 7 includes a hot water tank 8, a fountain nozzle 9, an air blower 10,
Control units 11 are respectively arranged. In the hot water tank 8, water supplied from the hose 6 is stored and heated to an appropriate temperature.

The fountain nozzle 9 has a double structure consisting of a plunger body 13 having a water fountain 12 at its tip and a cylinder body 14, and is formed so that the plunger body 13 extends to an appropriate position for cleaning. The hot water hose 15 is driven by
The plunger body 13 is pushed out by water pressure to spray water from the fountain port 12.

The blower device 10 includes a motor 16, a fan 17, and a wind cylinder 18. A heater is provided in the wind cylinder 18, and the heater is energized at the same time as the motor 16 is driven to blow hot air from the blower outlet 19. It is shaped to blow out.

The control unit 11 controls each operation button 2 shown in FIG.
Pump 5 and air blower 10 according to the operation of 0 and 21
At the same time, water temperature, water pressure, air temperature, etc. are adjusted according to the adjustment knobs 22.

FIG. 3 is an explanatory diagram showing the water supply piping route of this embodiment, and the water supply channel accompanying pump operation will be explained below. 23 is a water supply channel leading to the hot water tank 8 via the hose 6; 24 is the water fountain nozzle 9 from the hot water tank 8;
A hot water supply path 26 is a mixing waterway that branches from the water supply path 23 and connects to a mixing device 25 provided in the hot water supply path 24 .

The water that reaches the hot water tank 8 via the water supply channel 23 is
It is heated to a predetermined appropriate temperature within the tank, and is ejected from the nozzle 9 via the mixing device 25 as the pump 5 operates. The mixing device 25 has a function of varying the mixing ratio according to settings, similar to those found in known mixing faucets.
As the pump 5 operates, hot water and water brought from the hot water supply path 24 and the mixing water path 26 are mixed, and hot water at a set temperature is supplied to the nozzle 9.

27 is a safety device disposed between the mixing device 25 and the nozzle 9 in the hot water supply path 24, and is composed of a water temperature sensor and a solenoid valve that operates according to a signal from the sensor, and is used to supply water within the hot water supply path 24. This system detects when the hot water reaches a certain temperature and closes the valve to stop water supply. This prevents unintended high-temperature water from spewing out due to a temperature setting error by the user or a malfunction in the mixing device. ing.

According to the embodiment configured as described above, the hot water tank 8 constantly stores high-temperature hot water that has been heated to a temperature higher than that expected for use, and mixes this hot water at the time of use to obtain a fountain at an appropriate temperature. Further, by adjusting the mixing ratio in the mixing device 25, a desired water temperature can be obtained instantly.

[Effect of idea]

As is clear from the above description, in this invention, high-temperature hot water is stored in a hot water tank, and the capacity of the tank can be reduced by the high temperature of this hot water, making it possible to downsize the device. In addition, with conventional devices, the structure is such that the hot water is simply heated to a set temperature using a heater, so it is difficult to lower the temperature of the hot water, but with this proposal, the temperature can be lowered quickly by mixing, etc. The temperature of the wash water can be changed with good response, and the hot water always matches the temperature set by the user.
