Description

[Detailed description of the invention] Industrial applications The present invention relates to a fully automatic bath device for home use.

BACKGROUND OF THE INVENTION In recent years, technological developments regarding bath equipment for home use have been actively conducted. Of these, FIG. 4 is a longitudinal sectional view of a conventional fully automatic bath device, in which a hot water supply adapter 11 is attached to a bathtub 10.
, the hot water supply heat 11 is forcedly circulated through the hot water supply pipe 12 and the return pipe 13.
114 (hereinafter referred to as heat source 14) is connected.

Further, a drain port 15 is connected to the bottom of the bathtub 10, an automatic drain valve 16 is connected downstream of the drain port 15, and a drain 17 is connected downstream of the drain port 15.

Further, the water supply pipe 1B is connected to the heat source 14, and an electric signal line 20 that electrically connects the automatic drain valve 16 and the control section 19 is also connected.

Furthermore, the vertical cross-sectional structure of the hot water supply adapter 11 of the conventional device is such that an opening 31 connected to the hot water supply pipe 12 is connected to the hot water supply pipe 12 as shown in FIG.
An opening 32 connected to the return pipe 13 is fluidly open into the bathtub 10.

In the above configuration, when new hot water is automatically supplied from the heat source 14 to the bathtub 10, when the heat source 14 is activated, the automatic drain valve 16 connected to the bathtub 10 closes, and the amount of hot water that fills the bathtub 10 is supplied. The heat source 14 was to be stopped.

In addition, the hot water supplied from the hot water supply adapter 11 is supplied to the bathtub 10.
In contrast, it had a nozzle that supplied hot water only to the bottom.

Problems to be Solved by the Invention However, with the above configuration, dirt remaining in the bathtub 10 from the previous bath, such as hair and grime stuck to the bathtub 10, enters the newly filled water, causing damage to the fresh water. There was a problem that the hot water was dirty and contaminated with filth.

The present invention solves these problems and aims to provide a fully automatic bathing device that can automatically supply fresh, clean hot water.

Means for Solving the Problems In order to solve the above problems, the fully automatic bathing device of the present invention has the following features:
A water supply adapter is provided with a spray nozzle that sprays water, an automatic valve is provided between the spray nozzle and the hot water pipe, and immediately before hot water starts, water is sprayed from the spray nozzle for a predetermined period of time, and then a predetermined drainage period is allowed. The system is equipped with a control means that then closes the automatic drain valve and starts supplying hot water.

According to the above-described structure, the present invention uses the spray nozzle to clean the bathtub for a predetermined period of time immediately before pouring new hot water into the bathtub, and after draining water for a predetermined period of time, the automatic drain valve is closed and hot water is supplied, so that the filth remaining from the previous bath is removed. After draining the water, new hot water will be supplied.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a longitudinal cross-sectional view of one embodiment, and the points that differ from the conventional example are the configuration of the hot water supply adapter 1, the automatic valve 2 provided between the hot water supply adapter 1 and the hot water supply pipe 12, and the control means. It is 3.

That is, as shown in FIG. 2, the hot water supply adapter 1 according to the present invention has a configuration in which a spray nozzle 4 is provided, and the spray nozzle 4 is connected to a water supply pipe 12 via an automatic valve 2.

The control means 3 is connected to the automatic valve 2, the automatic drain valve 16 and the heat source 14 by an electric signal line 20, as shown in FIG.

In the above configuration, the operation sequence is as shown in the flowchart of FIG. 3. When the control means 3 is operated manually or automatically by a timer set, the automatic valve 2 is opened, the heat source 14 is operated, and a portion of the pressurized water is supplied. Pipe 12, automatic valve 2
The pressurized water is supplied to the rotary spraying nozzle 4 through the opening 31, and water is sprayed on the side surface of the bathtub 1G as shown in 5 to wash away the adhering dirt to the bottom surface.The remaining pressurized water enters the bathtub 10 through the opening 31 and washes away the bottom surface.

At this time, the automatic drain valve 16 is also opened, and the pressurized water mixed with dirt is discharged to the drainage drain 17.

After a predetermined time, usually 2 to 3 minutes, the heat source 14 is stopped, and the residual water remaining in the bathtub 10 is drained from the outlet 15 to the drain 17.
discharge to. After a predetermined period of time, typically 5 to 6 minutes, the automatic drain valve 16 and the automatic valve 2 are closed and the heat source 14 is restarted.
Hot water at an appropriate temperature is sent from the opening 31 to the bathtub lO, and since the automatic drain valve 16 is closed, the hot water accumulates. At this time,
Since the automatic valve 2 is closed, all hot water is discharged from the opening 31 when hot water is supplied.

At this time, if the automatic valve 2 is open, hot water will scatter from the spray nozzle 4 and the humidity in the bathroom will become high, which is not good.
This is not good as it accelerates the cooling of the water.

When the amount of hot water in the bathtub 10 reaches the preset amount, the water supply from the water supply pipe 12 is stopped, and then the return pipe 13 is stopped.
The hot water in the bathtub 10 is circulated from the bathtub 10 to the water supply pipe 12.
It detects a drop in the bath water temperature and reheats the water to maintain the appropriate temperature and automatically heats the bath.

In addition, although the case where one hot water supply adapter is provided has been described in the embodiment, it is preferable to provide a plurality of hot water supply adapters when cleaning all sides.

Effects of the Invention As described above, the fully automatic bath apparatus of the present invention provides the following effects.

(1) A water spray nozzle is provided on the hot water supply adapter, and water is sprayed for a predetermined period of time immediately before hot water supply starts, and then water is drained for a predetermined period of time, so there is an effect that the previous filth can always be washed away.

(2) Since the hot water supply adapter is equipped with a water spray nozzle, it is possible to clean both the bottom and sides of the bathtub.

(3) Since water is only sprayed for a predetermined period of time, the rise in humidity in the bathroom can be minimized.
