Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a private parts cleaning device, and more particularly to a structure for installing a heat exchanger for heating cleaning water.

If the heat exchanger is arranged horizontally in order to make the private parts cleaning device more compact, if air accumulates inside the heat exchanger, the heating effect of the cleaning water will deteriorate, so it is necessary to remove the air.

When draining water to prevent freezing, the water in the ceramic heater's outflow hole cannot drain unless it is tilted at an angle of 5 degrees or more, so the heat exchanger is mounted at an angle. If the inclination angle is too large, space efficiency will decrease and compact design will be difficult, and if it is less than 5°, water drainage will be difficult. As shown in the figure, the legs that are fixed at an angle are brazed to the heat exchanger to make it tilt at a predetermined angle.

However, since the heat exchanger has a complicated shape and the legs have a complicated shape, these machining processes are difficult to press, resulting in high costs. Because it is difficult to obtain dimensional accuracy for the
The drawback was that it was difficult to work with.

In addition, in the case of Figure 10 a, it is difficult to install the legs at the two locations unless the accuracy of the distance is improved because a gap will be created between the legs and the bottom plate as shown in Figure 10 b. There was also a drawback that it could not be tilted accurately to a predetermined angle.

The present invention aims to eliminate these drawbacks and to allow a heat exchanger to be mounted at a predetermined angle easily and inexpensively.

The basic structure of the present invention is to form an inclined part on the bottom surface of the housing cover, and place an oblong hollow heat exchanger on the inclined part, and a cleaning nozzle is connected to the approximate top of the heat exchanger. The location of the outlet prevents air from accumulating inside the heat exchanger.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

In the figure, A is the main water supply line, and in this line A, there is a branch fitting A1 solenoid valve from the upstream side, and a flow rate adjustment valve C1 integrally provided on the downstream side thereof, which also serves as a heat exchanger d1 and a check valve. 1 vacuum breaker, 1 vacuum breaker, 1 cleaning nozzle f, and the above cleaning nozzle f is the end of the water supply line A.

B is an auxiliary water supply line that branches off from the main water supply line A via a second vacuum breaker g that is integrally connected to the downstream side of the flow rate adjustment valve C, and an auxiliary nozzle h is provided at the end of the line. ing.

It should be noted that the second vacuum breaker g is also configured to function as a check valve like the first vacuum breaker e.

The main water supply line A and the auxiliary water supply line B have a functional section 1 downstream thereof including a solenoid valve and are housed and arranged in a housing cover 2, and the cleaning nozzle f and the auxiliary nozzle h are housed inside the housing cover 2. From the bottom of the front center of the storage cover 2
protrude outward.

The accommodation cover 2 consists of a box-shaped cover 3 with an open bottom and a bottom plate 4 detachably attached to the cover to close the open bottom, each of which is made of synthetic resin.

Further, on the bottom surface of the accommodation cover 2, that is, on the top surface of the bottom plate 4, there is a functional section 1.
The part of the functional part 1 where the heat exchanger d is attached is a sloped part 5, and the heat exchanger d is attached to the sloped part 5.

The heat exchanger d consists of a heating tank 7 equipped with a ceramic heater 6 and a hot water storage tank 9 which is brazed along the heating tank 7 and communicates with the heating tank 7 via a pipe 8. The tank 7 and the hot water storage tank 9 each have a horizontally elongated hollow shape and a cylindrical shape in the drawing, and a first vacuum breaker e is attached to the hot water storage tank 9, and cleaning is performed via the first vacuum breaker e. Contact nozzle f.

The heat exchanger d is provided with two mounting plates 10 at its bottom, and the plates 10 are fixed to the inclined portion 5 of the bottom plate 4 with fixing members 11 such as bolts and nuts.

and the heat exchanger d is installed at its outlet 1 in the condition
2 is located near the top.

- Therefore, such a private parts cleaning device has a bolt 14 that can be inserted into a mounting hole 13 formed in the bottom plate 4 of the housing cover 2.
A toilet seat 16, which is attached to the cover 2 with a nut 15 screwed thereon so that it can vibrate freely, corresponds to the upper surface of the rim 19 around the bowl portion 18 of the toilet bowl 17, and the cleaning nozzle f and the auxiliary nozzle h are placed inside the bowl bowl portion 18. It is used by being attached to the toilet bowl 17 so as to protrude.

In such a state of use, when the electromagnetic valve (S) of the private parts washing device is energized, the valve opens and the washing water supplied from the upstream side is sent to the flow rate regulating valve (C).

The flow rate adjustment valve C adjusts the flow rate of the cleaning water sent to it, and a part of it is sent to the heat exchanger d and heated by the ceramic heater 6 provided in the heating tank 7.

The temperature of the washing water is controlled by a controller 20, and the washing water heated to an appropriate temperature is sent to the washing nozzle f via the hot water storage tank 9 and the first vacuum breaker e.

Also, a part of the cleaning water is sent to the auxiliary nozzle h via the second vacuum breaker g.

When the user sits or straddles the toilet seat 16, the cleaning nozzle f is directed toward the user's anus or genital area, and the auxiliary nozzle h is directed toward the rear rim surface 19 of the toilet bowl 17, while jetting cleansing water at an appropriate temperature. to squirt out cleaning water.

Since the present invention has the above configuration, it has the following advantages.

■ A sloped part is formed on the bottom surface of the housing cover that houses the functional parts, and an oblong hollow heat exchanger installed in the middle of the cleaning line that connects the water supply source and the cleaning nozzle is attached to the sloped part and mounted in an inclined shape. Since the heat exchanger is fixed in place and the outlet for the cleaning nozzle is located near the top of the heat exchanger, the heat exchanger can be tilted at a predetermined angle, and the air inside the heat exchanger can be removed from the outlet. It is possible to prevent a decrease in heating efficiency, improve space efficiency, and enable a compact design.

■ The heat exchanger can be tilted at a predetermined angle simply by attaching it to the sloped part of the bottom plate, so unlike conventional heat exchangers, there is no need to process the heat exchanger itself with special slope processing or attach legs that are tilted and fixed to the bottom of the heat exchanger. There is no need for brazing, making installation easier, improving the workability of assembly work, reducing costs, and accurately measuring the dimensions of the heat exchanger itself relative to its inclination.

In addition, since the bottom plate has a small amount of molding, it is easy to process the sloped surface, and therefore, the increase in cost due to the provision of the sloped portion is negligible.
