Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a shower device that discharges hot water or water toward the user's body, particularly the lower body.

<Prior art> Conventionally, as this type of shower device, for example, Jitsuma M62-
As disclosed in No. 7 osso, a plurality of body shower spouts are provided in the vertical direction on the front surface of the shower tower body, and an over-rad shower spout is provided in the upper part facing downward, and the water spouts are connected to each of these spouts. An on-off valve and a flow rate adjustment valve are installed in the middle of the water supply pipe, and by operating the control unit, a preset instantaneous flow rate of hot water is discharged laterally from the body shower spout, hitting the entire body except the head, and overflowing. Some showerheads have a preset instantaneous flow rate of hot water discharged downward from the spout and mainly hit the head.

<Problems to be Solved by the Invention> However, in such conventional shower devices, the hot water or water only hits the lower body sideways or downwards, so the lower body, specifically the waist and buttocks, is exposed.

There is a problem in that it is not possible to sufficiently stimulate the thighs, legs, soles, etc. from below, and it is not possible to perform pine surgery on these areas.

Therefore, the water spout of the under shower is installed in the above-mentioned shower tower body upwards, and hot water at a preset instantaneous flow rate is directed upward from the water spout of the under shower in the same way as body showers and over-rad showers by operating the control unit. It is possible to discharge it and apply it to the lower body and soles of the feet.

However, in this case, when the under-shower starts discharging water, hot water at the set instantaneous flow rate is suddenly and forcefully discharged from the spout and hits the lower body and soles of the feet, which may surprise the user, and the under-shower is still unfamiliar. There is a problem in that the user feels uneasy about using the device, and the sudden discharge of water when the operation part is operated incorrectly gives the user a sense of discomfort.

In view of such conventional circumstances, the present invention prevents sudden water spouting at the start of under-shower water spouting and improves the lower back and buttocks.

The purpose is to provide moderate stimulation from below to the thighs, calves, and soles of the feet.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to provide a water spout facing upward at a position below the vertical center height position of the body, and to An on-off valve and a flow rate adjustment valve are installed in the middle of the connected water supply pipe, and when the on-off valve starts opening, the opening of the flow rate adjustment valve is throttled, and the opening of the discharge valve is loosened for a predetermined period of time to reach the preset opening. The invention is characterized in that it is provided with a starting flow rate adjusting means.

<Operation> According to the above-mentioned technical means, the start flow rate adjusting means changes the opening degree of the flow rate adjusting valve when the on-off valve starts opening, and discharges hot water or water from the spout at a small instantaneous flow rate for a predetermined period of time. At the same time, by subsequently increasing the instantaneous flow rate to bring it closer to the set flow rate, the hot water or water hits the lower body and soles of the feet.

Alternatively, you can narrow down the flow rate adjustment valve (5) by pressing either the "left" or "right" switch for the under shower, for example, the "left" switch (C2) without pressing the water stop switch (C4). At the same time, close the on-off valve (4) on the right side to reduce the flow rate to 1/2 of the above set flow rate, and close the on-off valve (4) on the right side.
The water spouting from 1) is stopped, and then the flow rate adjustment valve (5) is loosened, and the instantaneous flow rate of water spouted from the left water spout (1) approaches the set flow rate, and when it reaches the set flow rate, the flow rate is adjusted. The operation of the valve (5) is stopped and the instantaneous flow rate is maintained constant thereafter.

゛In the initial state, either the "left" or "right" switch for the under shower, for example the "right" switch (C
By pressing 3), the flow rate adjustment valve (5) is throttled and at the same time both on-off valves (4) (4) are opened and the left and right water spouts (1) are opened.
From step (1), the hot water or water with a low instantaneous flow rate will start discharging to the extent that it does not hit the body violently, and after a predetermined period of time, only the left on-off valve (4) will be closed and the water will be discharged from the left spout (1). The water spout is stopped, and then the flow rate adjustment valve (5) is loosened, and the instantaneous flow rate of water spouted from the right water spout (1) approaches the set flow rate, and when it reaches the set flow rate, the flow rate adjustment valve (5) is loosened. ) to stop its operation.

In this state, by pressing the water stop switch (C4), the right-hand on-off valve (4) is opened, and water discharge from the right-hand spout (1) is stopped.

In addition, by pressing the "left" switch (C2) for the under shower without pressing the water stop switch (C4), the right on-off valve (4) will be closed and water will be discharged from the right spout (1). At the same time as the water is stopped, the left on-off valve (4) is opened to start discharging water from the left water spout (1).

Furthermore, from this state, press the under shower "both" switch (C 1) Start discharging hot water or water from (1) to the extent that it does not hit your body violently, and then loosen the flow rate adjustment valve (5) to adjust the instantaneous flow rate of water discharged from both ridge water ports (1) and (1). When the flow rate approaches the set flow rate and reaches the set flow rate, the operation of the flow rate adjustment valve (5) is stopped.

In addition, (6) in the figure is the spout of the overhead shower,
(7) is the micro shower spout, (8) is the tap water spout, -(9) is the body shower spout, (

(7) (8) (9) The start and stop of water spouting from cM> is controlled so that at the start of each water spout, a set instantaneous flow rate of hot water or water is suddenly spouted out. Alternatively, a small instantaneous flow rate may be discharged, such as under-shower water, and the flow rate may be returned to the set flow rate after a predetermined period of time.

Next, the operation of such a shower device will be explained.

Under shower switch (c) on the operation panel (C)
i) If you touch (press down) any one of (C2) and (C3), both on-off valves (4) (4) or either on-off valve (4) will be activated based on the corresponding program.
At the same time, the start timing detection means (B7) first detects the automatic control start signal and outputs the detection signal to the start flow rate adjustment means (B8). By narrowing down the opening of the flow rate adjustment valve (5), the hot water or water supplied from the hot/cold mixer faucet (3) is supplied to each spout to the extent that it does not hit the user's body violently from each spout (1). The water will start discharging.

After a predetermined period of time, the instantaneous flow rate of hot water or water discharged increases by loosening the opening of the start flow rate adjustment means (B8) or the flow rate adjustment valve (5), and reaches the instantaneous flow rate set in the program, and each water outlet ( From 1), water is spouted diagonally upward toward the lower body of the user who is standing in front of the shower tower body (A).

If the user stands facing forward facing the shower tower (A), this upward water spout will hit the front of the waist, and if the user stands backward, it will hit the back of the waist and buttocks. It hits the thighs and calves.

In addition, if one foot is placed on the concave part (A2) on the top of the overhang part (A□) where hot water or water is spouted while standing, the sole of the foot will be touched and water will be spouted from both ridge water ports (1) (1). If you sit on a chair and place both feet on the recesses (A2) and (A2), they will hit the soles of both feet.

Furthermore, by touching the water stop switch (C4) on the operation panel (C), each on-off valve (4) that is in the process of opening is immediately closed, and water discharging from each water spout (1) is stopped. .
