Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble-generating bath equipped with a bubble nozzle for injecting hot water mixed with bubbles and a device for filtering the hot water, and more particularly to a structure for effectively filtering the hot water after bathing. It is a thing.

[0002]

2. Description of the Related Art A conventional air bubble generating bath filtration apparatus is constructed as shown in FIG. One or a plurality of bubble nozzles 4 are provided on the outer periphery of the bathtub 1, and a water absorption port 7 is provided at the bottom of the bathtub 1. The bubble nozzle 4 and the water absorption port 7 are communicated with each other through a bath hot water circulation path A. There is. A circulation pump 2 is inserted in the middle of the bath hot water circulation path A. By driving the circulation pump 2, the bath hot water is sucked from the water suction port 7 and discharged from the bubble nozzle 4. Can be circulated. A water suction pipe 8 is provided between the suction port 7 of the bath hot water circulation path A and the suction side 2b of the circulation pump 2.
A nozzle water supply pipe 9 is provided between the discharge side 2 a of the circulation pump 2 and the bubble nozzle 4. A bypass path B is provided between the discharge side 2a and the suction side 2b of the circulation pump 2 so as to bypass the bath hot water circulation path A, and the filtration tank 3 is inserted in the bypass path B. An air intake port 5 is provided on the flange of the bath tub 1, and the air intake port 5 and each bubble nozzle 4 are connected by an air supply pipe 6. A bubble operation control unit 10 and a bubble operation switch 11 are provided. By operating the bubble operation switch 11, the circulation pump 2 can be controlled via the bubble operation control unit 10. When the circulation pump 2 is operated, the bath water circulates as shown by the solid arrows in FIGS. 8 and 9 and air is sucked in as shown by the dashed arrows, and bubbles are entrained in the bath water by the bubble nozzle 4. A jet of bath water containing bubbles is ejected. On the other hand, as the bath water circulates, part of the bath water flows through the bypass route B, and dirt and dust are filtered in the filtration tank 3. In FIG. 9, b is air bubbles and b is dirt and dust.

[0003]

However, in the above-mentioned conventional example, when bathing while generating bubbles,
As shown in FIG. 9, dust and dirt in the bath water are floated on the water surface by the generated bubbles. On the other hand, since the water suction port 7 to the circulation pump 2 is at the bottom of the bathtub 1, the inflow amount of dirt and dust to the filtration tank 3 arranged in parallel with the circulation pump 2 is reduced, and the filtration efficiency is lowered. Therefore, the next bather will feel uncomfortable due to the dirty bath water.

In order to solve the above problem, the air suction port 5 can be closed and the circulation pump 2 can be operated after bathing and before the next bathing. However, the air suction port 5 is closed and the bubble operation switch 11 is turned on. The cumbersome operation of pushing is necessary. The present invention has been made in view of the above problems, and an object of the present invention is to perform highly efficient filtration with one touch or automatically, and to the next bather due to the pollution of the bath water. It is an object of the present invention to provide a filter device for a bubble-generating bath that does not cause discomfort.

[0005]

In order to achieve the above object, a filter device for a bubble generating bath according to the present invention comprises a bubble nozzle 4 provided in the bath 1 and a water inlet 7 provided in the bath 1 for a bath hot water circulation path A.
A circulation pump 2 for circulating the hot water in the hot water circulation path A is arranged, and a filtration tank 3 is arranged in a bypass path B provided in the middle of the hot water circulation path A. In a filter device for a bubble generating bath in which a nozzle 4 is in communication with an air supply pipe 6, an electric valve 13 for opening and closing this pipe is provided in the air supply pipe 6, and the electric valve 13 is opened to generate a jet flow involving air. It is characterized in that a bubble operation switch 11 for performing filtration while performing filtration and a filtration operation switch 14 for performing filtration while generating a jet so that air is not entrained by closing the motor-operated valve 13 are separately provided.

Further, after performing a bubble generation operation for generating a jet flow entraining air with the bubble operation switch 11, the motor-operated valve 13 is closed to automatically perform a filtration operation for performing a filtration while generating a jet flow not entraining air. It is also preferable that the above-mentioned control is performed and the filtering operation is manually performed by the filtering operation switch 14 provided separately from the bubble operation switch 11.

[0007]

In the former case of the above construction, when the bubble operation switch 11 is operated to generate bubbles and the bath is bathed, and then the filtration operation switch 14 is pushed, the electric valve 13 is closed and the circulation pump 2 is started. As a result, the suction of air from the air intake port 5 is blocked by the motor-operated valve 13, so that a jet of only hot water is discharged from the bubble nozzle 4. At this time, since it is not a jet stream containing bubbles, dirt and dust in the bath water do not float on the water surface of the bathtub 1 and the bath water is agitated. Therefore, more dust and dirt are sent to the circulation pump 2 and the filtration tank 3 through the suction port 7 as compared with the filtration while generating the jet flow containing the bubbles, and highly efficient filtration operation can be performed. After the filtration operation for a certain period of time, the circulation pump 2 is stopped and the electric valve 13 is returned to the open state. By performing this operation with one filtration operation switch 14 after bathing, it is possible to easily reduce the discomfort of the next bather due to the dirty bath water.

In the latter case of the above construction, after the bath operation is performed and the bath is taken, the motor-operated valve 13 is automatically closed and the circulation pump 3 is operated to perform the filtration operation. Further, the filtration operation can be performed by manually operating the filtration operation switch 14.

EXAMPLES First, the examples shown in FIGS. 1 and 2 will be described.
One or a plurality of bubble nozzles 4 are provided on the outer periphery of the bathtub 1, and a water absorption port 7 is provided at the bottom of the bathtub 1. The bubble nozzle 4 and the water absorption port 7 are communicated with each other through a bath hot water circulation path A. There is. A circulation pump 2 is inserted in the middle of the bath hot water circulation path A, and the water suction port 7 is driven by driving the circulation pump 2.
The bath water can be circulated so that the bath water is sucked in from and discharged from the bubble nozzle 4. A water suction pipe 8 is provided between the suction port 7 of the bath hot water circulation path A and the suction side 2b of the circulation pump 2, and the discharge side 2a of the circulation pump 2 is provided.
A nozzle water supply pipe 9 is provided between the nozzle and the bubble nozzle 4.
In the circulation pump unit, a bypass route B is provided between the discharge side 2a and the suction side 2b of the circulation pump 2 so as to bypass the bath hot water circulation route A, and the filtration tank 3 is inserted in the bypass route B. is there. An air intake port 5 is provided on the flange of the bath tub 1, and the air intake port 5 and each bubble nozzle 4 are connected by an air supply pipe 6. An electric valve 13 is arranged in the air supply pipe 6 between the air inlet 5 and the bubble nozzle 4, and all the air supplied to each bubble nozzle 4 is opened and closed by the electric valve 13. The motor-operated valve 13 is normally open. In addition to the air intake port 5, a bubble operation switch 11 and a filtration operation switch 14 are attached to the flange of the bathtub 1. Further, a switch for opening and closing the drain plug at the bottom of the bathtub 1 is attached to the flange of the bathtub 1. Further, a bubble operation control unit 10 and a filtration operation control unit 12 are installed in the circulation pump unit. The signals from the bubble operation switch 11 and the filtration operation switch 14 are transmitted to the bubble operation control unit 10 and the filtration operation control unit 12 so that the opening / closing of the electric valve 13 and the on / off control of the circulation pump 2 are performed. Has become.

The operation of the air bubble generating bath filtration device configured as described above will be described. First, the case of bubble operation will be described. When the bather presses the bubble operation switch 11, the motor-operated valve 13 is opened and the circulation pump 2 is started. As a result, the bath water circulates as indicated by the solid line arrow, and the negative pressure generated by the bubble generation nozzle 4 causes air to be sent from the air intake port 5 to the bubble nozzle 4 via the electric valve 13 as indicated by the broken line arrow. . As a result, the bather can enjoy the bath with the jet of air bubbles. Even in this state, the bath water circulates in the bypass route B of the circulation pump 2, so that the filtration tank 3 can perform filtration.

Next, the case of filtration operation will be described. When the bather presses the filtration operation switch 14 after bathing, the motorized valve 1
3 shifts to the closed state. The circulation pump 2 is started in response to the closed state of the motor-operated valve 13. As in the case of the bubble operation, negative pressure is generated in the bubble nozzle 4, but since the motor-operated valve 13 is in the closed state, suction of air is blocked. Therefore, a jet flow of only the hot water is generated from the bubble nozzle 4. At this time, since it is a jet flow of only the bath water, dirt and dust do not float on the water surface in the bath water due to bubbles, and float in the bath water as shown in FIG. The code B is dirt and dust. Therefore, the amount of dirt and dust in the bath water sent to the circulation pump 2 from the water suction port 7 provided at the bottom of the bathtub 1 is increased as compared with during bubble operation.
As a result, the amount of dirt and dust flowing into the filtration tank 3 that is attached to the circulation pump 2 increases, and efficient filtration can be performed as compared with during bubble operation.

Next, the embodiment shown in FIGS. 3 to 7 will be described. In the case of the present embodiment, the basic structure is the same as the above embodiment, but the control structures of the bubble operation switch 11, the filtration operation switch 14, the bubble operation control unit 11, and the filtration operation control unit 12 are different. That is, it is controlled so that when the bubble operation is finished by the timer, the operation automatically shifts to the filtration operation, and when the bather presses the bubble operation switch 14 again, the operation automatically shifts to the filtration operation. Has become.

By operating the bubble operation switch 11 and the filtration operation switch 14, the operation is performed as shown in the time chart of FIG. First, the case of bubble operation will be described. When the bather presses the bubble operation switch 11, the motor operated valve 13
The circulation pump 2 is started in the open state, and the bath water circulates as indicated by the solid arrow in FIG. On the other hand, due to the negative pressure generated in the bubble nozzle 4, air is sent from the air intake port 5 to the bubble nozzle 4 via the electric valve 13 as indicated by the broken arrow. This makes it possible to enjoy bathing with a jet of bubbles. The symbol a is a bubble. Even in this state, since the bath water circulates in the bypass route B of the circulation pump 2, filtration can be performed.

Next, the case of automatic filtration operation will be described. When the bather finishes the bubble bathing and finishes the bubble operation by the timer, the operation automatically shifts to the filtration operation. When the bather presses the bubble operation switch 11 again after bathing the bubbles, the bubble operation ends and the filtration operation automatically starts. When the operation automatically shifts to the filtering operation, the motor operated valve 13 shifts to the closed state. The circulation pump 2 is started in response to the closed state of the motor-operated valve 13. Bubble nozzle 4 as in the case of bubble operation
Although a negative pressure is generated at, the intake of air is blocked because the motor-operated valve 13 is closed. Therefore, a jet of only hot water is generated from the bubble nozzle 4 as shown in FIG. At this time, since it is a jet flow of only the bath water, dirt and dust do not float on the surface of the bath water due to air bubbles, but float in the bath water as shown in FIG. The code B is dirt and dust. Therefore, the amount of dirt and dust in the bath water sent to the circulation pump 2 from the water suction port 7 provided at the bottom of the bathtub 1 is increased as compared with during bubble operation. As a result, the amount of dirt and dust flowing into the filtration tank 3 that is attached to the circulation pump 2 increases, and efficient filtration can be performed as compared with during bubble operation. When the bather presses the bubble operation switch 11 again during the automatic filtration operation, the electric valve 13 shifts to the open state, and at the same time, the circulation pump 2 is stopped. If the bather does not press the bubble operation switch 11 again, the timer stops the filtration operation after a certain time, and the motor-operated valve 1
3 shifts to the open state, and the circulation pump 2 is stopped at the same time.

Next, the filtration operation which the bather can arbitrarily perform will be described. By pressing the filtration operation switch 14, the filtration operation can be arbitrarily performed after the automatic filtration operation. When the bather presses the filtration operation switch 14 again, the filtration operation ends. When the bather does not press the filtering operation switch 14 again, the timer operates to end the filtering operation after a certain period of time.

Table 1 shows the priority of the bubble operation switch 11 and the filtration operation switch.

[0017]

[Table 1]

As shown in Table 1, when the bubble operation switch is pressed in the stopped state, the bubble operation is performed, when the bubble operation switch is pressed in the bubble operation state, the automatic filtration operation is performed, and the bubble operation switch is pushed in the automatic and manual filtration operation states. And stop. When the filtration operation switch is pressed in the stopped state, automatic filtration operation is performed, when the filtration operation switch is pressed in the bubble operation state, manual filtration operation is performed, and when the filtration operation switch is pressed in the automatic and manual filtration operation states, the operation is stopped.

[0019]

As described above, according to the present invention, the air supply pipe is provided with an electric valve for opening and closing the pipe, and the air bubble operation switch for opening the electric valve to perform the filtration while generating the jet entrained with air and the electric valve There is a separate filter operation switch that closes the valve and performs filtration while generating a jet flow so that air is not entrained.Therefore, you can generate a jet flow of only hot water with one touch by operating the filter operation switch after bathing. It is possible to carry out circulation filtration, which makes it possible to create a state in which dirt and dust do not float on the surface of the bath water due to air bubbles, and float in the bath water. It is possible to increase the amount of dirt and dust that is sucked in from the water inlet at the bottom of the bathtub, so the amount of dirt and dust that flows into the filtration tank that is attached to the circulation pump increases, and during air bubble operation. Are those capable of performing a good filtration efficiency compared, the result, after bathing, in which it is possible to reduce the discomfort coming from dirtiness of easy bather the bathwater.

Further, in the invention according to claim 2 of the present invention, after the bubble generation operation for generating the jet flow entraining air by the bubble operation switch is performed, the electric valve is closed to generate the jet flow not entraining air. Since the filtration operation is performed automatically while performing the filtration, the system automatically shifts to the filtration operation when a signal indicating that the normal bubble operation is completed is received by the bather's intention or the timer operation. After the bath, the bather can automatically perform filtration with high filtration efficiency, so that the bather does not have to perform a troublesome operation such as pressing the filtration operation switch, and the discomfort of the next bather from the dirty bath water can be reduced. Is something that can be done. ,
