Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a bath device that can effectively utilize remaining hot water.

(B) Summary of the Invention This invention provides a bath device that supplies remaining hot water from a bathtub to a washing machine, and when a water supply request signal (water supply signal) is input from the washing machine to a control device, the water supply means is activated. By supplying water from the bathtub, it is possible to automatically supply water to the washing machine.

(C) Conventional Technology In general, the remaining hot water in the bathtub after bathing is often used for laundry, etc. To transfer this remaining hot water from the bathtub to a washing machine or the like, in conventional baths, this was done manually using a bucket or basin, or a submersible pump was installed each time.

However, using a bucket or washbasin is labor-intensive, especially when the bathtub and washing machine are installed far apart, and the water from the buckets and other items spills during transportation, causing floor damage. There was a problem with getting it dirty. On the other hand, those that use a submersible pump have the problem of being troublesome because they must be installed each time.

Therefore, in order to solve these problems, the inventor of this application proposed a bathtub, a hot water circulation path provided outside the bathtub and communicating with the inside of the bathtub, and a three-way valve provided in this circulation path.
A water flow urging means provided in the bathtub and the circulation path, a pipe that communicates with the three-way valve and leads hot water in the bathtub to the outside, and a pipe that connects the three-way valve to connect the circulation path or the bathtub. (Japanese Patent Application No. 59-231900) has been proposed and has already been filed.

On the other hand, fully automatic washing machines generally perform a cycle of water supply, washing, drainage, water supply, rinsing, and drainage, and the water supply is limited to city water.

(d) Problems to be solved by the invention If hot water is used in a washing machine, dirt will be easily removed, but since the fully automatic washing machine mentioned above uses city water for water supply, when used alone, it uses the remaining hot water from the bath. difficult to do. Therefore, it is possible to combine it with the bath device of the earlier application, but the bath device of this earlier application cannot detect the amount of water supplied to the washing machine, so the water supply operation is manually operated by turning on and off the switch. was. Therefore, there has been a problem in that water supply requires manpower and operation requires time and effort.

In view of the above, an object of the present invention is to provide a bath device that can supply remaining hot water from a bathtub to a washing machine without requiring much effort in operation.

(E) Means for solving the problems In order to solve the above problems, the bath device of the present invention has the following features:
The washing machine is provided with water supply signal output means for outputting a signal requesting water supply, water level detection means for detecting a predetermined water level in the bathtub, and setting means for setting the end of bathing, and when receiving the water supply signal. It is characteristically equipped with a control device having a water supply control means for operating the water supply means on the condition that the bathing end setting and the output of the water level detection means are present.

(f) Function In this bath device, a water supply signal is output at the timing when water supply is required on the washing machine side, so when the control device receives this water supply signal, it determines whether the end of bathing is set or not. It is confirmed whether or not there is a predetermined water level within the bath, and the water supply means is started to operate on condition that the bathing is completed and the predetermined water level is reached. The remaining hot water is then supplied from the bathtub to the inside of the washing machine via the water supply means.

Next, the operation of supplying water from the bathtub 2 to the fully automatic washing machine 31 in the above embodiment system will be described with reference to the flowcharts shown in FIGS. 2 and 3. In addition, in this embodiment system, in order to supply city water 24 to the bathtub 2 and burn the burner 22 to bring the water temperature in the bathtub 2 to a predetermined temperature, the personal computer 32
The control operations are performed by the following, but since these operations are not directly related to this invention, their explanation will be omitted.

When the personal computer 32 exits the water supply control routine and the combustion control routine to the bathtub 2, as shown in FIG. 2, it first determines in step ST (hereinafter abbreviated as ST) 1 whether or not bathing is complete. When the bather finishes bathing that day, when the bather or another person operates the bathing end key on the personal computer 32, the end of bathing is set in the personal computer 32. STI
If the end of bathing is not set in STI, the determination will be NO, and the wait signal S2 will be turned ON in Sr1.If the end of bathing is set in STI, the determination will be YES, and the process will be fully automatic washing from ST3 onwards. The water supply processing routine for the machine 31 is entered. That is, in Sr1, it is determined whether the wait signal S2 is set to 0FFL and the water supply signal S1 is ON (Sr1).

On the other hand, on the fully automatic washing machine 31 side, as shown in FIG.
When the water supply process is entered from other processes of 5T20 (washing, dehydration, drainage, etc.), the determination of water supply in 5T21 becomes YES, and the water supply signal s1 is output to 0NL (Sr22) and the personal computer 32.

In the personal computer 32, there is no need to supply water unless the water supply signal Sl is ON in Sr1, so the process moves to 5TIO and determines whether the drain switch is ON or not, but if the drain switch is also not pressed, the determination is NO.

This Sr1.5 is maintained until the water supply signal Sl is sent from the fully automatic washing machine 31 or the drain switch is turned on.
Stay at TIO and wait for some time.

When the water supply signal SL is turned on and there is a water supply request, the determination at Sr1 becomes YES, and then it is determined at Sr1 whether the low water level switch LSI is turned on or not.

When this low water level switch LSI is turned on,
This means that there is residual hot water in the bathtub 2, so the circulation pump P1 and three-way valve v2 are turned ON.

(Sr6), the hot water in the bathtub 2 is connected to the opening 2cm pipe 3a-
Circulation pump P1 → pipe 3b - filter 4 → pipe 3c
→Water is supplied to the fully automatic washing machine 31 through the three-way valve v2-vibro route. Then, until the water supply signal s1 turns OFF, Sr1.
...Repeat the Sr7 treatment and continue water supply.

If the low water level switch LSI is not turned on, it means that there is no hot water remaining in the bathtub 2. Therefore, if the determination of Sr1 is No, the water supply impossible signal S3 is turned on (Sr
8) This signal is sent to the fully automatic washing machine 31. Similarly, if the low water level switch LS1 is turned off during water supply, the water supply impossible signal S3 is turned on at that point (Sr
8), circulation pump P1 and three-way valve v2 are turned off (S
r9).

On the fully automatic washing machine 31 side, the water supply signal S1 is set to O at 5T22.
After N, check whether the wait signal S2 from the personal computer 32 is OFF (Sr23) and whether the water supply failure signal S3 is OFF (Sr23).
r24) Determine. If waiting signal S2 or water supply unavailable signal S
If any of 3 is ON, it will not be possible to receive water from bathtub 2, so water will be supplied by switching to city water (S
T26). Waiting signal S2 and water supply unavailable signal S3 are both OFF
In case F, water will be supplied from bathtub 2.

When a predetermined amount of water has been supplied, the water level detector inside the washing machine detects this, and the determination that water supply is complete becomes YES (
ST25), turn off the water supply signal S1 (ST27)
, move on to other processing.

In the personal computer 32 again, when the water supply signal si from the fully automatic washing machine 31 is OFF and the drain switch is turned ON, the judgment of 5TIO becomes YES, and then the entire load of the system is turned OFF (STll) and the water is drained. Turn on valve V3
Nishiku 5T12), open the hot water in the bathtub 2 2b = drain valve ■
3- Drain water through the route of pipe 8. Turn on drain valve ■3
After that, start a 10 minute timer, and when the time is up (Sr1.3), turn off the drain valve v3 (ST14)
.

In the above embodiment, a personal computer is used to control the system, but other controllers may be used instead.

(H) Effects of the Invention According to the bathtub device of the present invention, water is automatically supplied from the bathtub to the washing machine only when predetermined conditions are met in response to a water supply request from the washing machine. There is no need to operate Sui Sochi every time, which saves time and improves operability.
