Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bath water supply/discharge device capable of supplying and discharging hot water to a bath.

Conventionally, the hot water inlet and the hot water outlet of a bath were provided separately, and the hot water inlet was generally provided in the upper part of the hot water tank, and the hot water outlet was provided in the lower part. As a result, hot water is supplied from a high place, which can make a loud noise or get in the way of the faucet when hot water is being supplied, and if hot water is turned on when taking a bath, there is a risk of getting burned if you touch it. Ta.

The present invention has been made to solve the above problems, and its gist is that a large diameter drain pipe 1 is provided outside a mounting hole 6 made at the bottom of a hot water tank 5. The mouth of the small-diameter hot water supply pipe 2 installed in the center of the hot water supply pipe 2 is made to face the mounting hole 6, the spout 3 of the hot water supply pipe 4 screwed onto the hot water supply pipe 2 is made to face the hot water tank 5, and the head of the hot water tap 11 is made to face the hot water tank 5. A weight part 13 provided at the lower part of the hot water supply faucet 11 is provided so as to be freely movable up and down into the hot water supply pipe 4, and a drain port filter 10 provided inside the mounting hole 6 is made of an elastic material. A substantially cylindrical drain plug part 16 is removably fitted in the drain plug part 16, and a connecting column 15 provided at the upper part of the drain plug part 16 connects the drain plug part 16 to the flanged hot water inlet part 1 made of an elastic material and having a cavity.
2, the flange 14 provided on the outer periphery of the flanged hot water supply port 12 is elastically brought into close contact with the outer periphery of the drain plug 16, and is formed by protruding inward from the drain plug 16. Drill a hot water hole 17 in the inner flange, and open the hot water hole 17.
This is a hot water supply/drainage device for a bath in which a sprue part 3 of a hot water supply pipe 4 is fitted into the water supply pipe 4.

An embodiment of the present invention will be described below based on the drawings. A small diameter hot water supply pipe 2 is integrally formed in the center of a large diameter drain pipe 1, and a hot water supply pipe 4 having a sprue part 3 at the upper end is screwed to the upper part of the hot water supply pipe 2. The drain pipe 1 is provided with a gasket 7 interposed between its upper end and a mounting hole 6 made at the bottom of the hot water tank 5, and a gasket 8 that is connected to the top of the mounting hole 6. A drain filter 10, which is connected to the mounting hole 6 via the gasket 8, is fitted below the stopper 9 formed in the drain hole 9. Furthermore, a hot water tap 11 is installed inside the sprue 3 formed at the upper end of the hot water pipe 4.
A flanged hot water inlet part 12 is removably mounted on the outside. As shown in FIGS. 2a and 2b, the hot water tap 11 has a weight part 13 at the bottom, and when hot water is supplied to the hot water pipe 4, the water pressure opens the sprue part 3, and hot water is supplied. If not, it is provided so that the weight of the weight part 13 lowers the sprue part 3 and closes the sprue part 3. As shown in FIGS. 1 and 3, the flanged hot water inlet portion 12 is made of an elastic material and has a peripheral end of a flanged portion 14 provided on the flanged hot water inlet portion 12 elastically attached to the outer peripheral end of the drain plug portion 16. The drain plug part 16 and the flanged hot water supply port part 12 are connected by the connecting column 15 in close contact with the water supply hole 17, and the drain plug part 16 is fitted into the drain outlet filter 10. It protrudes into the cavity of the sprue portion 12 so as to be movable up and down.
The hot water supply hole 17 communicates with the inside of the flanged hot water supply spout part 12, and the internal height has enough room for the hot water tap 11 of the sprue part 3 that fits into the hot water supply hole 17 to rise when hot water is supplied. It is something that

In addition, 18 in the figure is the knob of the flanged hot water supply spout 12, and 1

4, 25, and 26 are Patsukin, respectively.

Since this embodiment is constructed as described above, in order to attach this device to the hot water tank 5, first remove the hot water supply pipe 4 from the hot water pipe 2, and install the drain pipe 4 from the bottom of the hot water tank 5 into the mounting hole 6 with the gasket 7 attached to the upper end. The pipe 1 is brought into contact with the drain filter 10, and the drain filter 10 is placed in the mounting hole 6 from above via the gasket 8.Then, the hot water pipe is screwed onto the hot water pipe 2, and the drain pipe 1 and the drain filter 10 are placed in the mounting hole 6. Tighten until it is tightly attached to 6. The flanged hot water inlet portion 12 can be attached or detached as necessary.
Needless to say, the drain hose 23 should be connected to the lower part of the drain pipe 1, and the hot water supply hose 20 should be connected to the lower part of the hot water supply pipe 2 via the connecting pipe 21.

Next, the water supply and drainage by this device will be explained.
First, hot water is supplied to the hot water tank 5 with the flanged hot water supply spout 12 attached, that is, with the hot water supply hole 17 fitted into the sprue 3 and the drain plug 16 fitted into the drain filter 10. This will be explained in detail below.

When the hot water supply handle 22 is opened and hot water is supplied to the hot water supply pipe 2 through the hot water supply hose 20, the hot water pushes up the hot water tap 11 at the spout 3 due to the hot water supply pressure as shown by the arrow in FIG. Flows into the mouth portion 12,
Furthermore, hot water is supplied into the hot water tank 5 by pushing out the flange 14 due to the hot water supply pressure. At this time, the drain plug section 16 of the flanged hot water supply port section 12 is fitted into the drain port filter 10, so that the flow of the supplied hot water into the drain pipe 1 is prevented. When the hot water supply handle 22 is closed, the hot water supply pressure decreases, the hot water faucet 11 is lowered by the weight of the weight part 13, the sprue part 3 is closed, and the upper and lower flanges 14 of the flanged hot water supply spout part 12 also decrease the hot water supply pressure. This results in a close contact at the peripheral edge. Therefore, there is no possibility that the hot water in the hot water tank 5 will flow back into the hot water supply hose 20 while hot water supply is stopped.

Further, the water tank 5 is drained by removing the flanged hot water supply port 12. When the flanged hot water supply port 12 is removed, as shown by the arrows in FIGS. 4 and 5,
The hot water (water) in the hot water tank 5 passes through the drain port filter 10, flows into the drain pipe 1, and is drained through the drain hose 23 to the sewer or the like.

At this time, the hot water faucet 11 closes the sprue 3 by the weight of the weight part 13, similar to when the hot water supply is stopped, so there is no risk of hot water (water) flowing back into the hot water supply pipe 2, etc.

As described above, according to this embodiment, hot water can be reliably supplied to and drained from the hot water tank 5, and this can be done at the bottom of the hot water tank 5, so that no noise is generated during hot water supply and there is no risk of burns.

Therefore, as can be understood from the description of the embodiments above, the present invention can fully achieve its intended purpose.

Although the present invention has been described with respect to a bath, it can also be used in a tank other than a bath for hot water, water, liquid, etc. where water is supplied and drained at the same location.
