Abstract

PROBLEM TO BE SOLVED: To permit a pump main body arranged inside a bath tub to be small and lightweight and also to eliminate an unpleasant feeling of a person to take bath next by catching a comparatively large organic matter such as hair or dirt and the comparatively small one such as the filth or fat of a man and keeping bath water clean and sanitary. SOLUTION: The pump main body 1 is arranged in the bath tub by an attaching board 22 which is set on the inner wall surface of the tub, power source equipment is disposed outside a bathroom which is isolated from the pump main body, the both of them are electrically connected by a power source cord 8 and an air bubble water stream is generated by a centrifugal pump which is incorporated inside the main body in the case of bathing and injected to the bath tub in an air bubble generator for the bath. The attaching board is provided with a coarse filter part 30 for catching the comparatively large organic matter such as hair in water and a dense filter part 28 for catching comparatively small organic matter such as filth and fat coming off from the body of a user so as to be freely attachable/detachable and the both filter parts are successively disposed on a sucking path 27 which leads to the sucking port 15 of the main body part 1 in the generator.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath air bubble generator in which a power supply is placed outside a bathroom, a pump main body is installed in a bath tub, and a centrifugal pump in the pump main body generates a bubble water flow to spray into the bath tub. It relates to improvement of the vessel.

[0002]

2. Description of the Related Art A conventional bath bubble generator of this type is shown in FIG.
As shown in the figure, the pump main body 1 is installed in the bathtub 34 by the suction cup 43 of the mounting plate 22 set on the inner wall surface of the bathtub 34, and the power supply 35 is connected to the pump main body 1 by the wall surface 36 so that water is not splashed. It is installed outside the shut off bathroom, and both are electrically connected by the power cord 8, and when taking a bath, a centrifugal pump incorporated in the pump body 1 generates a bubble water flow and injects it into the bath tub 34, and the jet flow The massage of the bather is performed.

In this bath bubble generator, relatively large organic substances such as hair and dust floating in a bathtub 34 are entangled with a pump runner or a pump shaft of a centrifugal pump incorporated in the pump body 1. In order to prevent the pump from locking, as shown in FIG. 3, a coarse filtration section 40 made of a foam material such as polyester foam or polyether foam is provided on the water suction side before reaching the pump runner or the pump shaft.

[0004]

However, although the relatively large organic substances can be captured by the coarse filtration section 40, relatively small organic substances such as dirt and fat which have fallen from the human body cannot be removed. For this reason, when a family of 4 to 5 takes a bath, dirt and fat, soap, shampoo, etc., which have fallen from the human body, are mixed with the bath water to form turbidity or adhere to the inner wall of the bath tub, which is very uncomfortable for those who take a bath later It was something. Also, because it causes hygiene and propagation of bacteria and infects the human body,
There has always been a desire for a clean and sanitary bath water holding method.

[0005] As a means for solving these problems, a filter for capturing relatively small organic substances such as human dirt and fats in addition to relatively large organic substances such as hair and dirt on the water suction channel side in the pump body 1. Although it is conceivable to separately install the filter unit, the pump main body 1 is large and heavy by the amount of the filter unit, and the handling and operability are deteriorated.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention utilizes a mounting plate for installing a pump body in a bathtub and compares the mounting plate with hair and the like in bathtub water. A coarse filtration unit that captures large organic matter and a dense filtration unit that captures relatively small organic matter such as dirt and fat that have fallen from the human body are provided.These coarse filtration unit and dense filtration unit are connected to the suction port of the pump body. It is a series of.

[0007] This makes it possible to reduce the size and weight of the pump main body, and at the mounting plate of the pump main body, relatively large organic substances such as hair and dust in the bathtub and relatively small organic substances such as human dirt and fat. , The bathtub water is kept clean and sanitary, and people who take a bath later do not become uncomfortable.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A pump main body is installed in a bath tub by a mounting plate set on the inner wall surface of the bath tub, and a power supply is installed outside the bathroom cut off from the pump main body, and both are electrically connected by a power cord. In a bath bubble generator that generates a bubble water flow by a centrifugal pump incorporated in the pump main body when bathing and sprays it into the bathtub, relatively large organic substances such as hair in the bathtub water are captured by the mounting plate. A coarse filtration section made of a foaming material such as polyester foam or polyether foam, and a porous ore with a large specific surface area that captures relatively small organic matter such as dirt and fat from the human body, activated carbon, etc. The coarse filtration section filled with the filter material is detachably provided, and the coarse filtration section and the fine filtration section are connected to the water inlet of the pump body.

Reference numeral 38 denotes a switch for turning on and off the power supply to the pump body 1. Reference numeral 39 denotes an air intake ball which is attached to the tip of the air suction hose 20 and also serves as a float.

The present invention is constructed as described above. Next, the operation thereof will be described. The power supply 35 is connected to the cord 8 of the pump body 1 and the switch 38 is operated to connect the drive motors 3 and 4 respectively. When a voltage of reverse polarity is applied, the right-rotation runner 11 and the left-rotation runner 12 rotate, and the water inlet 15 of the casing covers 13 and 14, the hole 32 of the filtration case 25, the dense filtration part 28, the hole 32, Filtration unit 3
0, the hot water in the bathtub 34 is sucked in through the hole 32, and the water flow is jetted into the bathtub 34 through the jet ports 16, 17 and the jet nozzle 33. At this time, a negative pressure is generated by the throttle nozzles 18 and 19, air is sucked through the air suction hose 20 and the air intake ball 39, and mixed with the jet water flow to form a bubble water flow. Thus, the bather performs massage bathing by the bubble jet.

During bathing, relatively large organic substances such as hair and dust in the bathtub 34 are trapped by the sponge-like filtering material 31 of the coarse filtering section 30, and relatively large organic substances such as dirt and fat, soap and shampoo. Small organic matter is trapped in the pores of the porous filtration material 29 of the dense filtration unit 28. The cleaning of the filter media 29 and 31 after bathing is performed by removing the filter media case 25 from the mounting plate 22 and performing a water washing process.

[0019]

As described above, according to the present invention, the following effects can be obtained.

(1) The mounting plate in which the pump body is set in the bath is used, and the filter body is provided with a double filtration section of a coarse filtration section and a dense filtration section, so that the pump body section is small and light. , Operability and usability are improved.

(2) Since a double filtration section, a coarse filtration section and a dense filtration section, is provided in the water channel before reaching the pump body, hair, dust, etc. are removed in advance and do not enter the pump section. No pump lock occurs.

(3) Since relatively large organic substances such as hair and dust are captured by the coarse filtration section, and relatively small organic substances such as human dirt and fat are captured by the dense filtration section, so that the bathtub water is clean. It is kept in a sanitary condition, and people who take a bath later do not become uncomfortable.

(4) Cleaning is simple and sanitary because the filter medium case is simply removed from the mounting plate and washed with water.
