Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device for washing local areas of a human body after use.

2. Description of the Related Art Conventionally, this type of sanitary washing device has a structure as shown in FIG. 4, for example, as shown in Japanese Utility Model Publication No. 59-41265.

That is, the sanitary washing device body 51 and the low tank 52 for washing the toilet 50 were provided on the toilet 50. Sanitary washing device body 51
There was a drain plug 53 at the bottom of the. Then, the water from the water supply source 55 provided with the main water stopcock 54 is supplied to the sanitary washing device main body 51 and the raw tank 52 by the branch water tap 56, respectively. The branch faucet 56 and the sanitary washing device main body 51 are connected via a connecting pipe 57, and the branch faucet 56 and the low tank are connected.
The ball tap 58 in 52 was connected by a water supply pipe 59.

The branch faucet 56 was as shown in FIGS. 5 and 6. 5 is a partially cutaway front view of the branch faucet 56, and FIG. 6 is a sectional view taken along the line I-I of FIG.

The branch faucet 56 consists of one inlet 60 and two outlets.
The inlet 60 was connected to the water supply 55. The outlet 61 supplied water to the raw tank 52, and the outlet 62 supplied water to the sanitary washing device body 51.

The inflow port 60 and the outflow port 61 were always in communication with each other. Further, the inflow port 60 and the outflow port 62 were communicated with each other via a water shutoff valve 63, a strainer 64, and a check valve 65.

Although the water shutoff valve 63 shown in FIG. 6 is in a fully closed state, it can be opened and closed by rotating the valve rod 66 with a screwdriver. The strainer 64 is located downstream of the water shutoff valve 63 and is attached to prevent foreign matter from entering the sanitary washing device body 51, and can be detached by removing the lid 67.

The check valve 65 was pressed against the check valve hole 69 by the spring 68 toward the primary side (water supply side). Therefore, the flow path from the inflow port 60 to the outflow port 62 can flow only in the direction from the inflow port 60 to the outflow port 62, and the reverse direction is blocked by the check valve 65. Therefore, when the water supply is cut off and the primary side has a lower pressure than the secondary side (downstream of the check valve 65), it is possible to prevent the backflow of dirty water from the sanitary washing device main body 51.

In the sanitary washing device, the connecting pipe 57, the branch faucet 56, the water supply pipe
59 (hereinafter referred to as the piping system) and the sanitary washing device 51 body
In normal use, it was full of water, and due to the constitution, the piping system was exposed to the outside air, so there was a possibility of freezing in cold regions. Once the piping system was frozen, the sanitary washing device could not be used until it could be thawed. Therefore, when there is a possibility of freezing, it was necessary to drain water in the piping system in advance.

The method of the draining operation is shown below.

First, the main water stop valve 54 of the water supply source 55 is closed. Next low tank 52
Lower the drain lever 52a of the
Drain to 50. Then, the ball of the ball tap 58 descends as the water level in the low tank 52 lowers, and the ball tap 58 opens. In this way, the ball tap 58 is opened to the atmosphere. Then, the drain plug 8 at the bottom of the sanitary washing device body 2 is removed to open the atmosphere. By this work, air enters the water supply pipe 59 through the ball tap 58, so that the water in the sanitary washing device main body 2, the connecting pipe 57 and the water supply pipe 59 is mostly drained from the hole of the water drain plug 53 by gravity.

The problem to be solved by the invention is that as the water in the connecting pipe 57 is drained, the check valve
The check valve 65 closes due to the repulsive force of the spring 68 that pushes the 65 back into the check valve hole 69. Then, air does not flow in from the check valve hole 69, and the water in the connecting pipe 57 is no longer drained and remains as residual water.

Incomplete drainage of the connecting pipe 57 in this way causes the following problems. That is, the residual water in the connecting pipe 57 may freeze in the cold district, especially at night, and the sanitary washing device cannot be used immediately in the next morning.

For reuse, it is necessary to pour hot water into the connecting pipe 57 to thaw it, which is troublesome, time consuming, and cannot be used immediately when necessary. Further, depending on the spring constant of the spring 68 and the state of the setting, a large amount of residual water may be generated in the connecting pipe 57, which may cause freeze damage, and there is a problem that repair such as replacement of parts is required for reuse. .

Therefore, the present invention provides a sanitary washing device that can drain water quickly and reliably and can be used without trouble even in cold regions.

Means for Solving the Problems And means for solving the above problems include a low tank for storing water for cleaning the inside of the toilet, a sanitary washing device body installed on the toilet, and water from a water supply source. The raw water tank is provided with a branch faucet for distributing to the sanitary washing device body, and a connecting pipe for connecting a connecting portion of the branch faucet and the sanitary washing device body, wherein the branch faucet is connected to the inlet and the connecting pipe. Of the branch faucet body having a first outflow port and a second outflow port to the low tank; a check valve provided between the inflow port and the first outflow port; It is composed of an air intake plug provided on the downstream side.

Operation By this technical means, when the air intake plug is pulled out, air enters the connecting pipe from the air intake plug, regardless of the check valve.
The water in the connecting pipe can be quickly drained by gravity.
