BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an intake structure of a bubble air pump for supplying bubble air to a bubble bath, and to facilitate replacement and maintenance of the air filter. belongs to.

[0002]

2. Description of the Related Art Conventionally, a unit bath is provided with a bath tub having a bubble nozzle pipe on a waterproof pan, and a bubble air pump provided on the back side of a ceiling panel. There is one that is supplied to a nozzle pipe (Japanese Utility Model Laid-Open No. 1-1112792, Japanese Utility Model Laid-Open No. 4-90330, Japanese Patent Laid-Open No. 7-124222, etc.).

However, in the above structure, since high humidity air in the bathroom is sucked, molds and bacteria are generated on the inner surface of a hose or the like forming an air intake passage, resulting in an unsanitary condition. And the problem of lowering electrical insulation. In particular, when molds, bacteria, and the like are generated, they are contained in the air bubbles in the bathtub and may be inhaled by bathers, causing diseases such as asthma. In addition, since the air pump generates heat due to the operation of the pump, the air pump is further heated by sucking high-temperature air in the bathroom, which may cause a breakdown or a shortened life.

Therefore, as a structure for solving the above problem, an air pump is provided outside the building outside the bathroom or on the back side of the ceiling panel to suck the air outside the bathroom with the air pump, and the suction port of the air pump. It is conceivable to provide a filter for air to remove dust and the like in the air.

[0005]

However, the air filter provided at the suction port of the air pump outside the bathroom is periodically replaced (for example, once or twice a year) or maintenance and inspection are performed. There is a need. However, since the air filter outside the bathroom is difficult to see, it is very difficult for the end user to replace the air filter, and the air filter may be left unattended. As a result, inconveniences such as extreme reduction of bubbles due to clogging of the air filter may be caused. In order to solve the above-mentioned problems, the present invention enables air outside the bathroom to be sucked by an air pump, and replaces or performs maintenance and inspection of the air filter from the bathroom (hereinafter, simply referred to as “replacement”). It is an object of the present invention to provide a suction structure of an air pump for air bubbles that can perform the following.

[0006]

According to the present invention, the air outside the bathroom can be sucked by an air pump and the air filter can be replaced from the bathroom. The above-mentioned means is a suction structure of a bubble air pump in which an intake port of a suction path of a bubble air pump is opened outside a bathroom, and an air filter is detachably provided in the suction path. An intake structure for an air pump for air bubbles, characterized in that an opening is provided, and the filter can be replaced from the bathroom through the opening. In addition, the air pump for air bubbles may be installed outside the bathroom or may be installed inside the bathroom. According to the present invention, the end user in the bathroom can remove the lid to open the opening, and can exchange the filter from the bathroom side through the opening.

According to a second aspect of the present invention, in order to cope with the characteristics of the structure of the bathroom, a part of the intake passage is provided in the bathroom, and a member forming the part is provided with a member. 2. An air intake structure for an air pump for bubbles according to claim 1, wherein an opening with a lid is provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an air intake structure of an air pump for a bubble according to the present invention.

(First Embodiment) FIG. 1 shows a first embodiment of the intake structure of the present invention, and is a front view in which a bathroom is sectioned. In this embodiment, the air pump 2 for air bubbles is used.
The intake port 3a of the intake path 3 is opened outside the bathroom B, and the intake path 3
An air filter 4 is detachably provided in the bathroom A, and an opening 6 with a lid 5 is provided in the bathroom A so that the filter 4 can be replaced from the bathroom A through the opening 6. Further, in the present embodiment, an exchange unit for attaching and detaching the filter 4 is made visible from the bathroom A through the opening 6.

The bathroom 1 includes a waterproof pan 8 placed on a gantry 7, a bathtub 9 placed on the waterproof pan 8, and a waterproof pan 8
Wall panel 10 erected from the peripheral portion 8b of the
And a ceiling bus 11 arranged so as to be joined to the upper end of the unit bus. Waterproof pan 8
Is provided with a washing place 8a. The ceiling panel 11 is provided with the opening 6 as an inspection port and includes a lid 5 for covering the opening 6 so that the lid 5 can be opened and closed from the bathroom A.

The air pump 2 for air bubbles is disposed on the back side of the ceiling panel 11 and below the pedestal 7, and is connected to an intake pipe forming the intake path 3 and has an air supply pipe forming the air supply path 12. It is connected. The air supply passage 12 passes through the wall panel 10 or the waterproof pan 8 and is connected to a bathtub-side air pipe 13 attached to the bathtub 9. The bathtub-side air pipe 13 is connected to a plurality of air nozzles 14 attached to the bathtub 9.
The air pump for air bubbles 2 pumps up low-humidity and low-temperature air outside the bathroom B taken in through the filter 4, and sends the air nozzle 1 through the air supply path 12 and the air pipe 13.
Supply to 4. The air outside the bathroom B, which was taken in outside the bathroom B,
When passing through the air pump 2, the heat generated by the air pump 2 is absorbed, and the pump 2 is cooled and at the same time becomes a heated high temperature state. The air supplied to the air nozzle 14 blows out into the hot water in the bathtub 9 and becomes bubbles. These bubbles stimulate the bather to stimulate blood circulation or relax the bather.

When replacing the air filter 4,
The operator opens the opening 6 by moving the lid 5 or the like, replaces the filter 4 with a new one while looking at the replacement part for attaching and detaching the filter 4, and finally moves the lid 5 to the original position. Then, the opening 6 is closed to complete the replacement operation.

(Second Embodiment) FIGS. 2 and 3 show a second embodiment of the intake structure of the present invention.
