Abstract

PURPOSE:To increase circulation and flow quantity during filtration operation to improve the filtration efficiency by making it possible to allow an air suction inlet to communicate with a bubbling nozzle or allow a bath tub to communicate with the bubbling nozzle by switching three-way valve installed in the joint part of an air supplying pipe and a communication pipe. CONSTITUTION:In a filtration apparatus for a bubble generating bath tub 1, in the cases where bubble generating operation is carried out, that is, a circulation pump 2 is operated in the condition that an air suction inlet 5 and a bubbling nozzle 4 communicated each other through an air supplying pipe 6 by a three-way valve 13, bath water which accompanys air from the bubbling nozzle 4 is jetted. Meanwhile, in the case where filtration operation is carried out, that is, the circulation pump 2 is operated in the condition that the bath tub 1 and the bubbling nozzle 4 communicate with each other by the three-way valve 12, only bath water is jetted out of the bubbling nozzle 4. At the time, since the jetted flow is not a flow including bubbles, scam and dust in the bath water do not float in the bath tub 1 and the bath water is stirred. Consequently, as compared with filtration in which jetted flow including bubbles is generated, a large quantity of scum and dust are sent to a filtration tank 3 from a water suction inlet 7 and thus filtration is carried out at high efficiency.

It is a thing.

[0002]

2. Description of the Related Art A conventional air bubble generating bath filtration device 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 water 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 two-way valve 13 'for opening and closing the flow path is arranged in the middle of the air supply pipe 6.
Reference numeral 10 is a bubble operation control unit, 11 is a bubble operation switch, and by operating the bubble operation switch 11, the circulation pump 2 is controlled via the bubble operation control unit 10 and the two-way valve 13 'is opened and closed. You can do it. 12
Is a filtration operation control unit, and 14 is a filtration operation switch. By operating the filtration operation switch 14, the circulation pump 2 is controlled via the filtration operation control unit 12, and the two-way valve 13 'is provided.
You can control the opening and closing of the. When the bubble operation switch 11 is operated to operate the circulation pump 2 and the two-way valve 13 'is opened, the bath water circulates as shown by the solid arrow in FIG. 4 and the air is sucked in as shown by the broken arrow. The bubbles are entrained in the bath water by the bubble nozzle 4, and the jet of the bath bath entraining the 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. When the filter operation switch 14 is operated to operate the circulation pump 2 and the two-way valve 13 'is closed, the bath water circulates without entraining air as shown by the solid arrow in FIG. 4, while the bath water circulates. By doing so, a part of the bath water flows through the bypass route B, and the filtration tank 3
The dirt and dust are filtered by. 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. 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 inflow amount of dirt and dust into the filtration tank 3 that is provided alongside the circulation pump 2 increases, and efficient filtration can be performed as compared to during bubble operation.

[0003]

However, when the two-way valve 13 'provided in the air supply pipe 6 is closed during the circulation operation in which air is not entrained as in the above-mentioned conventional example, the negative pressure of the bubble nozzle 4 is reduced. Negative pressure is generated in the generating portion, which increases pressure loss in the negative pressure generating portion. Therefore, the circulation flow rate is reduced, and thus the filtration efficiency is reduced.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a filter device for a bubble generating bath which can increase the circulation flow rate during filtration operation to improve the filtration efficiency. is there.

[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 an air bubble generating bath in which a nozzle 4 is in communication with an air supply pipe 6, a communication pipe 15 that communicates with the inside of the bath 1 is connected to the air supply pipe 6 and the air supply pipe 6 and the communication pipe 15 are connected. A three-way valve 13 is provided in the section, and by switching the three-way valve 13, the air intake port 5 and the bubble nozzle 4 are communicated with each other via the air supply pipe 6, or the inside of the bath 1 and the bubble nozzle 4 are communicated with each other by the communication pipe 15 and the air supply It is characterized in that they can be communicated with each other through the pipe 6.

[0006]

When a bubble generation operation is performed in which the circulation pump 2 is driven with the three-way valve 13 communicating the air inlet 5 and the bubble nozzle 4 via the air supply pipe 6, air is entrained from the bubble nozzle 4. A bath water is gushed out. In addition, when the three-way valve 13 performs the filtering operation in which the circulation pump 2 is driven in a state where the inside of the bath 1 and the bubble nozzle 4 are in communication with each other, the bubble nozzle 4 discharges a jet of only hot water. At this time, since it is not a jet of bubbles, dirt and dust in the bath water will not float up on the surface of the bathtub 1,
The bath water is agitated. Therefore, more dirt and dust are sent to the circulation pump 2 and the filtration tank 3 through the water inlet 7 as compared with filtration while generating a jet flow containing bubbles, and highly efficient filtration operation can be performed. At this time, the negative pressure generated by the bubble nozzle 4 causes the bath water to be sent to the bubble nozzle 4 through the communication pipe 15 and the air supply pipe 6 and jetted again into the bath 1. This alleviates the negative pressure in the bubble nozzle 4. By reducing the negative pressure, the pressure loss of the bubble nozzle 4 is reduced, and the circulation flow rate of the bath hot water circulation path A is increased.
The filtration efficiency is increased.

The bubble nozzles 4 and the water absorption port 7 form a bath hot water circulation path A. I am communicating with. 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 water inlet 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 2a of the above 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. One end of the communication pipe 15 is connected to the air supply pipe 6, and the communication pipe 15
The other end of is connected to the bottom of the bath 1. A three-way valve 13 is arranged at the connecting portion between the air supply pipe 6 and the communication pipe 15,
By switching the three-way valve 13, the communication pipe 15 side is closed during the bubble operation so that the air suction port 5 and the bubble nozzle 4 communicate with each other through the air supply pipe 6, and the air suction port 5 side is closed during the filtration operation. A communication pipe 15 for connecting the inside of the bathtub 1 and the bubble nozzle 4
And the air supply pipe 6 for communication. 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. Bubble operation switch 11
The signal from the filter operation switch 14 and the filter operation switch 14 is transmitted to the bubble operation control unit 10 and the filtration operation control unit 12 so that the three-way valve 13 is switched and the circulation pump 2 is turned on and off.

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 circulation pump 2 is started in a state where the communication pipe 15 side is closed by the three-way valve 13 and the air suction port 5 and the bubble nozzle 4 are communicated by the air supply pipe 6. . As a result, the bath water circulates as shown by the solid line arrows in FIGS. 1 and 2, and the negative pressure generated by the bubble generation nozzle 4 causes air to flow from the air intake port 5 as shown by the broken line arrows in FIGS. It is sent to the bubble nozzle 4 via the three-way valve 13. 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 (state of FIG. 3) will be described. When the bather presses the filtration operation switch 14 after bathing, the three-way valve 13 closes the air intake port 5 side so that the bathtub 1 and the bubble nozzle 4 communicate with each other through the communication pipe 15 and the air supply pipe 6. . The circulation pump 2 is started in response to this state. Bubble nozzle 4 as in the case of bubble operation
However, since the three-way valve 13 closes the air intake port 5 side, suction of air is blocked. On the other hand, the inside of the bathtub 1 and the bubble nozzle 4 have a communication pipe 15 and a three-way valve 1
3 communicates with each other via the air supply pipe 6, the bath water is sent to the bubble nozzle 4 via the communication pipe 15 and the air supply pipe 6 at the negative pressure and is ejected from the bubble nozzle 4. 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 surface of the bath water due to air bubbles, but float in the bath water. 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. At this time, the bath water is sucked through the communication pipe 15 and the air supply pipe 6 by the negative pressure generated in the bubble nozzle 4, so that the pressure loss in the bubble nozzle 4 is small and the bath water flowing in the bath hot water circulation path A is small. The circulation flow rate of the bath water increases, the flow rate of the bath water flowing through the bypass route B also increases, and the filtration efficiency increases.

When the bather presses the bubble operation switch 11 again during the automatic filtration operation, the three-way valve 13 is used for the air intake port 5.
The side is opened and the air inlet 5 and the bubble nozzle 4 communicate with each other via the air supply pipe 6, and at the same time, the circulation pump 2 is stopped. When the bather does not press the bubble operation switch 11 again, the timer works so that the filtering operation is finished after a certain period of time and the three-way valve 13 shifts to the air intake port 5 side to the open state.
At the same time, the circulation pump 2 is stopped.

[0011]

Since the present invention is constructed as described above, the bath water is sent to the bubble nozzle through the communication pipe, the three-way valve and the air supply pipe by the negative pressure generated by the bubble nozzle during the filtration operation. The pressure loss of the bubble nozzle is reduced by relaxing the negative pressure of the bubble nozzle itself by relaxing the negative pressure in the bubble nozzle, and the circulation flow rate of the bath hot water circulation path is increased. Along with that, the filtration flow rate increases, and the filtration efficiency increases.
