Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for a bath-cooker which is attached to a lower suction port and an upper discharge port of a recirculating bath-cooking type bath cooker.

[0002]

2. Description of the Related Art Conventionally, as a filter for a bathtub attached to a lower suction port or an upper discharge port of a circulation cooker type bathtub, there is a filter for preventing dust from entering the bathtub. It was only. However, in order to use the bath comfortably, it has been demanded that the filter for the bath kettle be provided with a further function.

The present invention not only prevents the entry of dust into the bath kettle, but also prevents the generation of slime and mud, suppresses the cooling of the hot water, and keeps the hot water in the bathtub clean for a long time. It is an object to provide a filter for a bath pot.

[0004]

According to the first aspect of the present invention,
A filter for a bathtub attached to the lower suction port and upper discharge port of a circulation cooker type bathtub, comprising a filter for the suction port attached to the lower suction port and a filter for the discharge port attached to the upper discharge port. The filter for the suction port has a filter part for dust removal, a check valve, and a filter part for cleaning. The filter part for dust removal is made of a porous sheet, and the check valve is a lower suction part. The passage of water toward the back of the mouth is allowed, but the passage of water toward the front from the back of the lower suction port is prevented,
The filter for cleaning is designed so that the passing water comes into contact with the activated carbon, and the filter for the outlet is designed so that the passing water contacts the antibacterial agent and ceramics having far-infrared radiation performance. Features.

[0005] As the antibacterial agent, for example, silver, copper and the like are used, but the present invention is not limited thereto.

As the ceramic, for example, tourmaline-based, silicon-based, and alumina-based ceramics are used, but are not limited thereto.

[0007]

FIG. 1 is a longitudinal sectional view of a bath kettle provided with a bath kettle filter of the present invention. Bath pot 1
Is formed in the wall 3 of the bathtub 2, and is configured such that a lower suction port 4 and an upper discharge port 5 are connected by a U-shaped tube 6. The filter for a bathtub of the present invention comprises a filter 7 for the suction port attached to the lower suction port 4 and a filter 5 for the upper discharge port.
And an outlet filter 8 attached to the outlet.

FIG. 2 is an enlarged vertical sectional view of the suction port filter 7. As shown in FIG. The suction port filter 7 includes a dust removal filter unit 71, a check valve 72, and a cleaning filter unit 7.
3 is comprised.

The filter 71 for removing dust is made of a bay-like sheet having a diameter larger than the opening diameter of the lower suction port 4, and the sheet is porous enough to prevent dust, hair, hair, etc. from passing through. It is.

As shown in FIG. 3 which is an enlarged view of a portion A in FIG. 2, the check valve 72 is brought into contact with a ring-shaped flange 722 which is circumferentially continuous with a disc-shaped valve body 721. The filter unit 71 for removing dust from the filter unit 73 for cleaning
When the valve body 721 comes into contact with the protrusions 723 provided at appropriate intervals in the circumferential direction as shown by the dashed line in FIG. 3, the flow of water to the side is blocked, as shown by the arrow B in FIG. Thus, the flow of water from the dust removal filter 71 to the cleaning filter 73 is allowed.

The cleaning filter portion 73 is a porous case 731 in which activated carbon 732 is filled so as not to leak out of the case.

The filter 7 for suction port is composed of a filter part 71 for dust removal, a check valve 72, and a filter part 73 for cleaning, which are constructed as described above, so as to be disassembled and integrated into one. The filter portion 73 is fitted in the lower suction port 4.

FIG. 4 is an enlarged longitudinal sectional view of the outlet filter 8. The outlet filter 8 includes a filter 81 for removing dust, a filter 82 for cleaning, and a filter 83 for removing bacteria. The dust filter unit 81 and the cleaning filter unit 82 have the same configuration as the dust filter unit 71 and the cleaning filter unit 73. That is, the cleaning filter unit 82
Is a porous case 821 filled with activated carbon 822 so as not to leak out of the case.

The filter section 83 for disinfection is formed by filling a porous case 831 with an antibacterial agent 832 and ceramics 833 exhibiting a far-infrared ray effect so as not to leak out of the case.

The outlet filter 8 includes a dust removing filter section 81, a cleaning filter section 82,
And the filter section 83 for disinfection are combined so as to be able to be disassembled and are integrally formed.
In addition, the filter section 83 for sterilization is fitted in the upper outlet 5.

Next, the operation of the bath kettle filter having the above configuration will be described. When hot water is put in the bathtub 2 and additional cooking is performed in a state where the hot water has spread to the bath kettle 1, a flow of hot water as shown by an arrow C in FIG. 1 is generated. That is, the hot water at the bottom of the bathtub 2 passes through the inlet filter 7 and flows into the U-tube 6, flows as shown by the arrow C, passes through the outlet filter 8, and is discharged to the upper portion of the bathtub 2. Is done.

At this time, in the suction port filter 7, when hot water passes through the dust removal filter 71,
Garbage, hair, hair, etc. in the hot water are removed. The hot water that has passed through the dust removal filter unit 71 presses the valve body 721 against the protrusion 723 in the check valve 72 and flows as indicated by the arrow B in FIG. When the hot water passes through the cleaning filter unit 73, the activated carbon 73
Since it comes into contact with 2, the slime in the hot water is removed by being absorbed by the activated carbon 732.

In the outlet filter 8,
When hot water passes through the filter section 83 for sterilization, the antibacterial agent 83
2 and the ceramics 833, so that the hot water is sterilized and warmed by the far-infrared effect. Furthermore,
When hot water passes through the cleaning filter 82, the activated carbon 8
22, the slime in the hot water is removed by being adsorbed on the activated carbon 822. Then, when hot water passes through the dust removing filter portion 81, dust, hair, hair, and the like in the hot water that has passed through the suction port filter 7 are removed.

When the additional cooking of the bath kettle 1 is stopped, gradually the arrow C
However, the flow in the direction opposite to the arrow C does not occur because the suction port filter 7 has the check valve 72. Therefore, the hot water radiated at the top of the bathtub 2 and cooled to a low temperature is prevented from accumulating at the bottom of the bathtub 2 through the bathtub 1.

[0020]

As described above, according to the filter for a bathtub of the present invention, the following effects can be exhibited. (1) The dust filter portion of the suction port filter prevents dust, hair, hair, etc. from entering the bathtub, thereby facilitating maintenance of the bathtub.

(2) Since the flow of hot water from the bathtub to the bathtub in the suction port filter can be prevented by the check valve of the suction port filter, it is possible to prevent low-temperature hot water from accumulating at the bottom of the bathtub. It is hard to cool hot water.

(3) The cleaning filter section of the suction port filter can prevent the slime from entering the bathtub, and this also facilitates maintenance of the bathtub.

(4) The hot water heated by the far-infrared rays can be discharged to the bathtub by the filter for the discharge port, so that the hot water in the bathtub can be cleaned and the warmth of the hot water can be maintained.

(5) The hot water in the bath tub can be circulated while removing dirt, slime and the like in the hot water and disinfecting the hot water by the inlet filter and the outlet filter. The generation of mud can be prevented, and the bath water can be kept clean for a long time.
