Cleaning becomes more reliable.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the embodiment of the present invention has an appliance main body (within a hot water supply device) that is equipped with a gas burner (B) in a heat exchanger (5) for hot water supply to supply hot water using gas-fired power.
1O) and the bathtub (2), the hot water supply device can directly fill the bathtub (2) with hot water, and the temperature of the hot water supply can be set using a temperature setting device. This is implemented in a whirlpool bath device, in which the appliance main body (lO) and the bathtub (2) are connected to each other through a hot water filling circuit (30) and a cleaning circuit (33), and the water filling circuit (30) and the cleaning circuit (33) are connected to each other. (30) has a drying valve (31) and a cleaning circuit (3).
3) is provided with an on-off valve (12).

Further, as shown in the figure, the drainage circuit (1) is formed to communicate with the bottom of the bathtub (2) and to be introduced into the appliance main body (10), and a drainage completion detection means is provided on the outlet side of the drainage circuit (1). A normally closed water flow switch (11) is provided.

Furthermore, the water flow switch (1
A timer (T) and a delay capacitor (C) activated by the output of 1) are provided.

The control circuit of this automatic cleaning device has a configuration as shown in Fig. 3, in which a water flow switch (11) is connected in series to a parallel circuit of a timer (T) and a delay capacitor (C). The normally open output contact (13) of the timer (T) is inserted into the circuit to the on-off valve (12).

In addition, in this embodiment, by operating each operation switch provided on the operation panel (6), at least the drying operation, the draining operation, the adjustment of the timer (T), and the draining are possible. .

A publicly known hot water filling device is used for automatic hot water filling, and when the hot water filling switch on the operation panel (6) is operated, the water filling valve (31) opens and heat exchange is started. The hot water supply circuit of the vessel (5) and the hot water filling circuit (30) will be in communication, and the hot water supply circuit (30) will be connected to the hot water bath (2).
It is filled with hot water.

Next, to drain the remaining water in the bathtub (2), operate the drain switch (7) on the operation panel (6), and then the drain valve (7).
0) is opened and the residual water is drained from the drain circuit (1) communicating with the bottom of the bathtub (2).

At this time, if a water flow is generated in the drain circuit (1) by draining water from the drain circuit (1), the normally closed water flow switch (
11) is in an open state, and after that, when drainage is completed,
The water flow switch (11) detects this and enters the closed state (O
Return to N).

As a result, a timer (T) set in advance for a certain period of time is activated, the normally open output contact (13) is closed for a certain period of time, the on-off valve (12) is opened during this period, and the hot water supply circuit is connected.・The cleaning circuit (33) will be connected, and the cleaning water of water or hot water will pass through the cleaning circuit (33) from the cleaning shower opening (3) as shown in Figures 1 and 2. , is sprayed all around the circumference of the bathtub (2).

In addition, a delay capacitor (C) is installed in parallel with the timer (T) to prevent the timer (T) from momentarily operating immediately after the start of drainage.

Then, after a certain period of time has passed, the timer (T) stops and the normally open output contact (13) returns to the open state. Along with this, the on-off valve (12) becomes the closed state and hot water is supplied. The circuit and the cleaning circuit (33) are cut off, and the jetting of the cleaning water (W) from the cleaning shower opening (3) is also automatically stopped. In addition, the cleaning shower opening (3
) is set slightly upward so that the wash water (W) reaches above the hot water storage water level (I) on the entire circumference of the inner peripheral wall of the bathtub.

That is, in this device, when the drain switch (7) on the operation panel (6) is operated to drain the residual water in the bathtub (2), the cleaning shower port formed on the inner peripheral wall of the bathtub (2) is automatically opened. From (3), the washing water (W) flows like a shower for a certain period of time.
As a result, dirt such as hot water scale on the inner peripheral wall of the bathtub (2) can be washed away.

Next, in the embodiment shown in Figure N4, the on-off valve (12) is opened after a certain period of time has elapsed from the drainage operation, and in this embodiment, the on-off valve (12) starts to open. The timing is set by the first timer (T1) which is activated by the drain switch (7) for drain operation, its output contact is inserted in series into the circuit of the timer (T), and the timing of this latter timer (T) is set. It is designed to remain in operation for a set period of time.

After the draining operation, the cleaning operation proceeds when the set time of the first timer (Tl) has elapsed, and is completed when the set time of the timer (T) has elapsed.

The setting time of the first timer (T1) should be set to the time required for the water level in the bathtub to drop to the position of the cleaning shower opening (3) after the draining operation, or set to the time required for the water level in the bathtub to drop to the position of the cleaning shower opening (3) after the draining operation, or at the time when the draining is completed. Set it to the required time.

Furthermore, if the cleaning operation is allowed to proceed until the water level in the bathtub falls to the position of the cleaning shower opening (3), a flow may occur in the water surface in the bathtub along the bathtub wall even during drainage. As a result, it is possible to reliably prevent hot water scale from adhering to the bathtub wall.

Next, as shown in FIG. 5, it is also possible to configure a timer (T) connected in series with the drain switch (7). In this case, the cleaning operation will proceed simultaneously with drainage. Therefore, in this case, the setting time of the timer must be set to at least the time required for drainage.

In this case, if the cleaning shower opening (3) is arranged above the hot water level (H), the cleaning effect will be further improved.

Although this example was applied to a high-temperature whirlpool type bathtub, it goes without saying that the present invention can also be applied to natural circulation type or forced circulation type bathtubs. may be made to flow into the cleaning circuit (33) from a tank (not shown) during cleaning.
