Abstract

PURPOSE:To curtail the number of washing nozzles, and also, to reduce the water quantity required for washing. CONSTITUTION:The whirl pool bath is constituted so that rinse washing is executed by a jet operation executed by jet nozzles 2, 3 using remaining water. Accordingly, since the jet nozzle is used as a washing nozzle 6 as well, the number of washing nozzles 6 can be curtailed, and also, since remaining water is used, the water quantity required for washing can be reduced compared with a conventional practice.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a whirlpool bath having a jet function of sucking hot and cold water from a suction port of an inner wall of a bathtub and ejecting hot and cold water containing bubbles from a plurality of jet nozzles installed on the inner wall of the bathtub. ..

[0002]

2. Description of the Related Art Generally, in a conventional automatic cleaning bathtub, a large number of, for example, 10 baths are used to rinse and wash the entire inner wall of the bathtub.
The number of dedicated cleaning nozzles is required, and the amount of water supplied from the water heater to the cleaning nozzle during cleaning is also large.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object thereof is to reduce the number of cleaning nozzles and the amount of water required for cleaning.

[0004]

In order to achieve the above object, the present invention is configured as follows.

That is, the present invention is a jet that sucks hot and cold water from the suction port of the inner wall of the bathtub and jets hot and cold water containing bubbles from a plurality of jet nozzles installed on the inner wall of the bathtub above the suction port. A whirlpool bath having a function, in response to an operation for performing automatic cleaning, by controlling a drain plug at the bottom of the bathtub, the level of hot and cold water in the bathtub between the suction port and the jet nozzle is controlled. It is provided with a control means for cleaning the inner wall of the bathtub by discharging the hot water from the suction nozzle by controlling the jet function by discharging the hot water from the jet nozzle.

[0006]

According to the above construction, at the time of cleaning, the water is drained to a level between the suction port and the jet nozzle above it, and the hot and cold water sucked from the suction port is ejected from the jet nozzle to clean the inner wall of the bathtub. Since the number of dedicated cleaning nozzles can be reduced and the residual water in the bathtub is used, the amount of water required for cleaning can be reduced.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a schematic block diagram of an embodiment of the present invention. In the figure, 1 is a bathtub, 2 is a jet nozzle that is attached to the back side wall surface of the bathtub 1 along the horizontal direction, and 3 is a jet nozzle that is attached to the foot side wall surface of the bathtub 1 along the horizontal direction. Nozzles 4 are jet nozzles 2 and 3
A whirlpool for sucking hot and cold water in the bathtub 1 through the suction port 4 and jetting hot and cold water mixed with bubbles into the bathtub 1 from the jet nozzles 2 and 3 is provided on a wall surface below the suction port 4. A unit, 6 is a cleaning nozzle attached to the lower wall surface of the bathtub 1, 7 is a water heater for supplying hot and cold water, 8 is a drain plug provided at the drain port at the bottom of the bathtub 1, 9 is a wall surface of the bathroom, etc. The remote control transmitter 10 is a controller as a control unit that controls each unit in response to an operation signal from the remote control transmitter 9.

The whirlpool bath of this embodiment has the following structure in order to reduce the number of cleaning nozzles and the amount of water required for cleaning.

That is, a water level sensor 11 is provided on the inner wall of the bathtub 1 at a position slightly above the suction port 4, and the controller 10 controls the bottom of the bathtub when the automatic cleaning switch of the remote control transmitter 9 is operated. The hot water in the bathtub 1 is drained to a level between the suction port 4 and the jet nozzles 2 and 3 by controlling the drain plug 8 of the above, and in this state, the whirlpool unit 5 is controlled to suck the hot water from the suction port 4. The hot water is jetted from the jet nozzles 2 and 3 to clean the inner wall of the bathtub 1, and then the drain plug 8 is opened to complete drainage.
Finally, the water heater 7 is controlled to rinse the bottom of the wall surface and the bottom surface of the bath 1 with the cleaning nozzle 6 attached to the bottom wall surface of the bath 1, and then the operation is completed.

FIG. 2 is a diagram showing a procedure for this automatic cleaning.

When the automatic washing switch of the remote control transmitter 9 is operated in the state shown in FIG. 2A in which the bath 12 is closed and the lid 12 of the bath 1 is closed, the controller 10 causes the drain plug 8 to operate.
Open to start draining, as shown in Figure 2 (B),
The water level sensor 11 drains the hot water in the bathtub 1 until it reaches the level between the suction port 4 and the jet nozzles 2 and 3, and when the level is reached, the drain plug 8 is closed to drain the water. To stop.

Next, in this state, the controller 10
The whirlpool unit 5 is controlled to start the jet operation. That is, as shown in FIG. 2C, the hot and cold water sucked from the suction port 4 below the water surface is jetted from a total of four jet nozzles 2 and 3 above the water surface to wash the inner wall of the bathtub 1. The amount of water ejected from these jet nozzles 2 and 3 is about 100 l / min,
The amount is sufficient for rinsing and cleaning the wall surface of the bathtub 1.

Here, the rinsing and washing is to wash away hair, dust and the like in the bathtub 1, and there is no problem even if the hair catcher of the whirlpool unit 5 or jet water that has passed through the filtration tank is used. It is a thing.

Further, in this embodiment, during the automatic cleaning, the amount and direction of the jet water jetted from the jet nozzles 2 and 3 are changed so that the wall surface of the bathtub 1 can be sufficiently rinsed and washed. The jet nozzles 2 and 3 have the structure shown in FIG. That is, the needle 14 that is movable toward the discharge port 13 from which hot water from the pump of the whirlpool unit 5 is discharged is provided, and by moving the needle 14 toward the discharge port 13, the discharge port 13 is discharged. The flow rate can be increased by narrowing down. In FIG. 3, reference numeral 15 is an air supply path, 16 is a nozzle opening, and 17 is a wall surface of the bathtub 1.

After the jet operation is continued for a predetermined time in this way to perform rinsing and washing, the jet operation is stopped and the drain plug 8 is opened to completely drain the water, as shown in FIG. 2 (D).

Next, as shown in FIG. 2 (E), rinsing and washing are carried out for a predetermined time by the washing nozzle 6 attached to the lower wall surface of the bathtub 1 and the bottom of the wall surface and the bathtub which cannot be washed by the jet operation. Finish by rinsing the bottom of 1.

As described above, in the automatic cleaning, the jet operation is performed by the residual water to perform the rinse cleaning, and after the drainage is completed, the cleaning nozzle 6 performs the rinse cleaning. It is possible to reduce the number of
Accordingly, the piping can be omitted, and since the residual water is used, the amount of tap water required for cleaning can be reduced, and the cost can be reduced.

[0019]

As described above, according to the present invention, since the jet nozzle is also used as the cleaning nozzle and the residual water in the bath is used for rinsing and cleaning, the number of cleaning nozzles can be reduced. In addition, the amount of water required for cleaning can be reduced.
