DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an immersion type bath water treatment apparatus for immersing the bath water in a bath tub and performing a filtration treatment of the bath water.

[0002]

2. Description of the Related Art A home immersion type bath water treatment device used by immersing it in bath water of a bath tub includes a bath water filtration device for filtering bath water, a bath water insulation device for keeping bath water warm, There is a bath water filtration / insulation device for filtering and keeping the temperature of the bath water.

For example, an immersion type bath water filtration device includes a filter, a circulating pump, and an electric motor in an immersion case, and drives the circulating pump by the electric motor so that bath water in the tub is filtered by the circulating pump. The method employs a method of filtering the bath water in the bath tub with a filter while circulating between the baths.

In a conventional immersion type bath water filtration device, an electric motor having no ordinary waterproof function is used, and this electric motor is installed in a closed chamber of an immersion case, and its rotating shaft is projected from the closed chamber. Connected to circulation pump.

[0005]

Conventionally, since an electric motor is incorporated in a closed chamber in an immersion case, when the entire apparatus is immersed in bath water of a bathtub, the entire apparatus receives large buoyancy and its stability. There is a drawback that becomes worse.

That is, there is a closed chamber containing a large amount of air in the immersion case, and the closed chamber serves as a floating body, so that large buoyancy is generated in the entire apparatus. For this reason, there is no problem in the case of a structure that is large and heavy and is installed on the bottom of the bathtub. However, in the case of a small and light weight, the buoyancy of the entire device makes it easy to lift up, and the stability is greatly impaired.

[0007] For example, in the case of a small household size, it has been considered to mount the immersion case on the side wall of the bath tub or the like via a suction cup or other mounting means so as not to hinder bathing. However, since the entire device is relatively light and there is a sealed chamber that becomes a floating body inside the immersion case, its mounting means has a structure that can keep the immersion case in the immersion state against buoyancy. Will be needed.

In particular, when the bath is mounted on the side wall of a bathtub, the level of the bathwater in the bathtub always changes greatly due to the ingress and egress of the bather, pumping of the bathwater, hot water supply, and the like, and the surface of the bathwater has large undulations. Therefore, in a state where the immersion case receives a large buoyancy and tends to lift up, there is a problem that the immersion case floats in an unstable manner due to a change in water level, ripples, and the like. Therefore, in a conventional device in which an electric motor is incorporated in a sealed room, a strong stabilizing function is required for the mounting means itself in order to ensure sufficient stability.

The present invention has been made in view of the above-mentioned conventional problems, and as a result, it is possible to prevent lifting due to buoyancy as much as possible, to ensure stability in a bathtub, to prevent the mounting means and the like from being enlarged, and to further reduce the electric motor. It is an object of the present invention to provide an immersion-type bath water treatment apparatus capable of preventing a short circuit or the like from occurring.

Next, a method of using the bath water filtering apparatus 2 having the above configuration will be described. First, prior to using the bath water filtration device 2, the hanging tool 66 is fixed to the upper surface of the side wall 1 a of the bathtub 1 with an adhesive or the like so that the hook 67 protrudes inward from the side wall 1 a of the bathtub 1. On the other hand, a hanging string is inserted into the through hole 65 of the pump case 9.
3, the knot 3a is formed on the hanging string 3 while adjusting the length of the hanging string 3 in accordance with the hanging position of the bath water filtration device 2.

Next, the hanging string 3 is hooked up to the hook 67 of the hanging tool 66.
After that, the suction cup 4 is pressed against the side wall 1a of the bathtub 1 to be adsorbed, and the position of the bath water filtration device 2 in the bathtub 1 is determined. After that, when the bath water W is put into the bath tub 1 until the whole of the bath water filtration device 2 is immersed in the bath water W, the bath water W enters the inlet.
From 82, it passes through the inside of the filter case 10 and fills the inside of the circulating pump 7, and becomes operable.

Further, as the water level of the bath water W in the bathtub 1 rises, the bath water W enters the pump case 9 from the lower water inlet 108. At this time, the air in the pump case 9 escapes from the upper water inlet 114. When the bath water W accumulates in the bath tub 1 until the entire bath water filtration device 2 is immersed in the bath water W, the pump case 9 is filled with the bath water.

Therefore, as compared with the case where the pump case 9 is constructed in a closed state, the floating of the bath water filtration device 2 due to buoyancy can be easily prevented, and the posture of the bath water filtration device 2 in the bath water W is stabilized. However, even if the surface of the bath water W has a wavy surface, the bath water filtration device 2 does not float unstably. Moreover, the heavy mineral eluate 115
, The lifting of the bath water filtration device 2 can be prevented by its weight. Mineral eluate at the same time
Since minerals are eluted from 115, bath water W can be made slightly alkaline.

When removing the bath water filtration device 2 from the bathtub 1, it is easy to remove the suction cup 4 from the side wall 1 a of the bathtub 1 and then remove the hanging string 3 from the hanging tool 66. When changing the mounting height of the water filtration device 2,
It can be easily performed by changing the position of the knot 3a to adjust its length or changing the hanging string 3 itself.

Next, when the electric motor 8 is started, the rotor 32 containing the magnet 31 rotates around its axis, and the circulating pump
7 is driven. Then the bath water W in bathtub 1 becomes
The liquid is sucked into the filter case 10 from the inflow port 82, and is discharged from the suction port 26 of the pump case 9 through the respective pipe lines 41 and 42.
27, the bath water W is circulated between the bath tub 1 and the filter 6, and the hair, dust, etc. contained in the bath water W can be removed by the filter 6, and the bath water W in the bath tub 1 can be removed. Can be filtered and cleaned.

There is a projection 87 on the lower surface of the upper bottom plate 72 of the filter case 10, so that the filter 6 does not come into close contact with the upper bottom plate 72 by contact of the squirt. When flows, the flow is smooth.

Since the filtered bath water W is ejected from the discharge port 27 into the bath 1, the bath water filtering device 2 is operated by the reaction force of the bath 2.
1 is pressed against the side wall 1a. Therefore, the bath water filtration device 2
During use, the suction power of the suction cup 4 does not decrease, and the bath water filtration device 2 can be stably held in the bath water W in combination with the above-described floating prevention effect.

Since dust such as hair adheres to the filter 6, the filter 6 is periodically washed to remove dirt. In cleaning the filter 6, first, while supporting the filter case 10 by hand, the lower end sides of the left and right coupling members 96 are operated outward to remove them from the engagement portions 106, and then the filter case 10 is removed from the pump case 9. Pull it out and take it out of bathtub 1.
Then, the upper bottom plate 72 is removed from the filter case main body 71, and the filter 6 is taken out of the filter case main body 71.

The filter 6 may be rubbed and washed with tap water or the like. In addition, the filter 6 after washing may be put in the filter case 10, and the filter case 10 may be mounted on the lower side of the pump case 9 in the reverse order.

Therefore, the pump case 9 is connected to the side wall 1 a of the bathtub 1.
The filter case 10 can be easily attached to and detached from the pump case 9 in a state where the filter 6 and the filter case 10 are still attached, and the filter 6 and the filter case 10 can be easily washed. Further, since there is no need to take out the bath water filtration device 2 itself from the bath 1, the filter 6 and the filter case 10 can be easily washed even during bathing.

The present invention is not limited to the above embodiment, but can be implemented in various other modes. For example, when the bath water filtration device 2 is mounted in the bath tub 1, when the amount of the bath water W is small, the bath water filtration device 2 may be mounted obliquely. Further, since the bath water filtration device 2 is used by immersing it in the bath water W, it is desirable to use a DC motor of about 24 VDC for the electric motor 8, but it is not limited thereto. A simple non-displacement pump may be used as the circulation pump 7, or a positive displacement pump may be used.

In the embodiment, the hanging string 3 is used on the upper side and the suction cup 4 is used on the lower side as a mounting means. When the suction cups 4 are used, they may be arranged on the left and right as well as on the top and bottom.

Further, in the embodiment, the immersion type bath water filtration device provided with the filter 6 for filtering the bath water W has been exemplified. It is also possible to apply to immersion type bath water treatment equipment other than the filtration equipment. Therefore, the present invention is not limited to the immersion type bath water filtration device.

In place of the mineral eluate 115, a weight simply for preventing floating may be used. As the weight in that case, for example, there is a metal plate, a metal lump, pebbles, a stone lump, or the like, and the weight may be filled or fixed inside the pump case 9. The weight in the pump case 9 may be omitted.

Further, the water inlets 108 and 114 may be provided at the upper and lower portions of the pump case 9 and are not limited to the positions in the embodiment. The number may be determined as appropriate.

[0063]

According to the present invention, the circulation pump 7 and the electric motor
The pump case 9 is provided with water inlets 108 and 114 through which the bath water W flows in and out, and the electric motor 8 is waterproof, so that floating due to buoyancy can be prevented as much as possible. This has the advantage that the stability of the electric motor 8 can be secured, the mounting means and the like can be prevented from being enlarged, and the electric motor 8 can be prevented from leaking.

Further, the circulating pump 7 is provided in the pump case 9.
In addition, since the weight 115 other than the electric motor 8 and having a specific gravity larger than the bath water W is provided, the lifting of the weight 115 can be prevented, and the stability in the bath water W is improved.

Further, a bath water is filled in the space in the pump case 9.
Since mineral-eluted body 115 having a specific gravity larger than W is filled, the mineral-eluted body 115 prevents floating, improves stability in bath water W, and enhances bath water W.
Has the advantage that mineral components can be eluted.

A filter case 10 containing a filter 6 for filtering the bath water W is disposed below the pump case 9, and a connecting member 96 for detachably connecting the filter case 10 to the pump case 9 is provided. Therefore, the filter case 10 can be easily attached and detached, and the filter 6 in the filter case 10 can be easily cleaned. Further, since the water inlet 108 is provided inside the attachment portion 105 of the connecting tool 96 on the pump case 9 side, the water outlet 108 is hardly noticeable from the outside.

Further, mounting means 3, 4 for mounting the pump case 9 on the bathtub side are provided, and the pump case 9 of the mounting means 3, 4 is provided.
Since the water inlet 114 is provided inside the mounting part 112 on the side,
The water inlet 114 becomes less noticeable from outside.
