Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bathtub cleaning device, and more particularly to a bathtub cleaning device that automatically cleans a bathtub after bathing.

[Conventional technology]

Generally, after taking a bath, scale, which is mainly composed of metal salts of fatty acids, lipids, free fatty acids, proteins, etc., adheres to the inner walls of the bathtub. In order to clean this limescale,
Conventionally, cleaning has been carried out using bathtub detergent and brushes, depending on the availability.

[Problem that the invention attempts to solve]

In the above-mentioned conventional technology, cleaning was extremely time-consuming because the scale had to be cleaned manually. In addition, the use of brushes for cleaning has caused the problem of damaging plastic and stainless steel bathtubs.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to provide a bathtub cleaning device that can automatically clean a bathtub without damaging it.

[Means for solving problems]

To achieve the above object, the cleaning device according to the present invention includes a detergent spraying mechanism that rotates and sprays bathtub detergent on the inner wall of the bathtub, and a cleaning water sprinkling mechanism that rotates and sprays water.

[Effect]

After a predetermined period of time has elapsed after the detergent spraying mechanism sprayed the detergent onto the inner wall of the bathtub, the washing water sprinkling mechanism sprays water, and the scale adhering to the inner wall of the bathtub is cleaned by the detergent and water pressure.

This makes it possible to automatically clean the inner wall of the bathtub to which scale has adhered, and also to prevent the bathtub from being damaged.

〔Example〕

Hereinafter, one embodiment of the bathtub cleaning device according to the present invention will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is a cross-sectional view of a bathtub equipped with a bathtub cleaning device according to this embodiment, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a cross-sectional view of a motor pump section.

As shown in FIGS. 1 and 2, the cleaning device according to this embodiment includes a rotating shaft 3 provided at the end of an apron 11 of a bathtub 1, one end of which is rotatably held by the rotating shaft 3, and the other end of which is rotatably held. A cleaning arm 2 is provided with a water spray nozzle 22 rotated by water pressure and a detergent spray nozzle 21 rotated by a motor pump section 23 at the end, and a detergent passage pipe 25 is divided into the detergent spray nozzle 21 of the arm 2. Detergent tank 4 that supplies detergent
, a flushing valve 5 that supplies tap water to the water nozzle 22 through a water passage pipe 24 , and a controller 6 that controls opening and closing of the flushing valve 5 and instructs driving of the motor pump section 23 . ing. The water sprinkling nozzle 22 is a well-known mechanism that performs water sprinkling while being rotated by the water pressure of the supplied tap water. It is sucked and sprayed, and the nozzle 21 is rotated.

The detailed structure of this motor pump section 23 is shown in FIG. The illustrated pump section 23 includes a motor 26 that rotationally drives a rotating shaft 27 according to instructions from the controller 6, a small-diameter gear 28 and a medium-diameter gear 32 attached to the rotating shaft 27, and the rotational force of the gear 28. is provided through a large-diameter gear 29 to promote the supply of detergent; a large-diameter gear 33 that converts the rotation of the gear 32 to low-speed rotation; , the detergent supply section 34
and a nozzle rotating section 35 that supplies detergent supplied from the spray nozzle 21 to the spray nozzle 21. This detergent supply section 34 is connected to a gear 3 rotated by the gear 29.
0, and a gear 31 that meshes with the gear 30 and rotates to suck liquid detergent through the detergent passage pipe 25 and discharge it to the nozzle 21,
The rotation of the gear 31 causes liquid detergent to be delivered to the nozzle 21.
The nozzle rotating section 35 is rotatably supported. Therefore, this motor pump section 23 is operated by the rotation of the motor 26.
The detergent is sprayed from the nozzle 21 and the nozzle 21 is rotated.

In the bathtub cleaning device configured in this way, after the user takes a bath and drains the bathtub water, the user rotates the cleaning arm 2 so that the tip of the arm 2 is attached to the bathtub as shown in FIG.
position it in the center of the Thereafter, when the operator operates the controller 6, the motor pump section 23 rotates the motor 26 to drive the detergent supply section 34, sucking detergent from the detergent tank 4 through the detergent passage pipe 25, and By rotating the rotating part 35, the spray nozzle 21 is rotated.
As a result, the detergent is evenly sprayed onto the inner wall 12 of the bathtub 1 while the spray nozzle 21 rotates.

After a predetermined period of time, for example 40 minutes, has passed since the spraying and the scale has been released from the inner wall 12, the controller 6 opens the flush valve 5 and supplies tap water to the water nozzle 22 through the water passage pipe 24. Water nozzle 22
The inner wall of the bathtub 1 rotates due to the water pressure of the tap water.
2. Cleaning is performed by sprinkling water to wash away the scale.

As described above, according to the present invention, the inner wall of the bathtub 1 after taking a bath
After the detergent is sprayed on the bathtub 1 and the scale is released, the scale and detergent are washed away with water.
In addition to automatically cleaning the inner wall 12 of the bathtub, damage to the inner wall 12 of the bathtub can be prevented since no brushes or the like are used. In addition, cleaning arm 2
Since it is rotatable, it can be moved onto the bathtub apron 11 as shown by the arrow in FIG. 2 when taking a bath, and does not get in the way of bathing.

In the above embodiment, the cleaning tank is provided in the bathtub apron, but the present invention is not limited to this, and may be housed inside the cleaning arm, for example.

[Effect of idea]

As described above, according to the present invention, the detergent spray nozzle located in the center of the bathtub rotates and sprays detergent onto the inner wall of the bathtub, and after a predetermined period of time, the water spray nozzle washes away the liberated scale and detergent. , the bathtub can be easily cleaned.
