Description

TECHNICAL FIELD The present invention relates to a method for cleaning and draining a bath, and more particularly to a method for cleaning and draining the inner surface of a bath at the same time when the hot water in the bath is drained.

[Prior art and its problems] In recent years, the automation of bath equipment has been remarkable, and it is extremely possible to refill the bathtub and set the temperature of the bath, as well as to reheat the bath or adjust the temperature of the shower by using the operation panel in the bathroom. It's easy to do.

However, with respect to cleaning of the bathtub, generally, an old-fashioned method of rubbing the side wall of the bathtub with a rubbing tool such as a scrubber is performed, and this bathtub cleaning is quite troublesome.

As described above, in the bath apparatus, the steps after the filling of water are automated, and even though remote operation is possible, the bath cleaning work up to that point can be performed only manually. It cannot be said that the advantages are fully utilized.

In order to solve such a problem, Japanese Patent Laid-Open No. 63-97122 proposes an automatic drainage operation and a cleaning operation. In this product, a certain amount of water is supplied prior to the drainage operation, and ultrasonic cleaning is executed with the water level raised.
Then drain. Further, after the completion of drainage, a fixed amount of water is supplied before closing the drain plug, and this water supply cleans the inner surface of the bathtub.

However, with this product, ultrasonic cleaning is performed to remove the scale that has adhered to the surface of the residual water, so it is necessary to install a device for ultrasonic cleaning in the bathtub. Is complicated and exaggerated.

Also, in the process of cleaning and draining, it is necessary to supply water twice, and it is necessary to perform the ultrasonic cleaning, which complicates the cleaning and draining operation.

The present invention has been made in view of such a point, in the "drainage of the remaining hot water in the bathtub, the bathtub cleaning drainage method in which the cleaning of the inner peripheral wall of the bathtub is associated", without using an ultrasonic cleaning device, The task is to be able to wash and drain with various actions.

[Invention of Claim 1] [Technical Means] The technical means of the present invention taken to solve the above-mentioned problems include: a drainage circuit (1) connected to a bathtub and opened by drainage operation; and a bathtub inner peripheral wall. A cleaning shower port (3) is provided in the interior of the bathtub (2) by ejecting cleaning water (W) from the cleaning shower port (3) during the drainage operation by the drainage circuit (1). I tried to clean the surrounding walls. "

[Operation] The above technical means operates as follows.

When the drainage operation is performed, the drainage circuit (1) is opened and the drainage operation proceeds. During the drainage operation, the jetting operation of the wash water (W) from the wash shower port (3) proceeds and the wash water (W ) Is sprayed on the inner peripheral wall of the bathtub (2). That is, the bath wall cleaning operation proceeds during the drainage operation.

Wash water (W) ejected from the shower port for washing (3)
Is blown down on the inner peripheral wall of the bathtub (2) and then flows down to the boundary between the water in the bathtub (hereinafter referred to as residual water) and the inner peripheral wall of the bathtub (boundary between the residual water and the bathtub wall). . At this time, the wash water (W) diverts from the inner peripheral wall of the bathtub via the boundary line to a direction in which it slides on the surface of the residual water and flows toward the center of the water surface.

Then, the dirt washed off with the washing water (W) and the dirt originally floating in the residual water are caused by the washing water (W) flowing toward the central portion of the water surface of the residual water, and thus the bathtub. It can be moved slightly in a direction away from the inner peripheral wall. That is, it is possible to prevent dirt originally floating in the residual water in the bathtub or dirt washed from the inner wall of the bathtub from contacting the inner wall of the bathtub. It becomes difficult to adhere.

As a result, the drainage operation can be advanced while preventing the dirt from adhering to the inner peripheral wall of the bathtub.

[Effect] When the washing operation is performed after the drainage operation is completed, the dirt floating on the water surface is sequentially deposited on the inner wall of the bathtub at the boundary between the water surface that descends during drainage and the inner wall of the bathtub. Go. On the other hand, according to the above technical means, it is possible to proceed the drainage operation while preventing the adhesion of dirt to the bathtub,
A high cleaning effect can be obtained. Further, since the dirt that has once adhered is not washed off but is washed and drained so that dirt does not adhere, the amount of water or hot water required for cleaning can be small.

Further, since the drainage operation and the cleaning operation are executed at the same time, it is not necessary to supply water again when the water distribution is completed, and the cleaning and draining operation can be simplified accordingly, and the ultrasonic cleaner as in the above-mentioned conventional technology is unnecessary. Becomes

* Regarding the invention of claim 2, the present invention, in the invention of claim 1 described above, enables cleaning by a shower directly from the inner peripheral wall of the bathtub (2), and the technical means adopted for this purpose is " A washing shower port (3) is provided on the inner peripheral wall of the bathtub (2), and washing water (W) is jetted obliquely upward from the washing shower port (3) to make the entire circumference of the inner peripheral wall of the bathtub (2). I sprayed it on.

[Operation] The above technical means of the present invention operates as follows.

When the cleaning shower port (3) provided on the inner peripheral wall of the bathtub (2) is opened, the cleaning water (W) is jetted obliquely upward from the cleaning shower port (3).

Since this cleaning water (W) is sprayed on the entire circumference of the inner peripheral wall of the bathtub, the cleaning water (W) is sprayed near the upper edge of the bathtub by appropriately setting the ejection speed of the cleaning water (W). It will be sprayed on the inner wall. Therefore, the cleaning water (W) flows down from the wall surface portion near the upper edge of the bath (2), and drains dirt such as scales of water adhered to the flow-down area.

[Effects] The present invention having the above-described configuration has the following unique effects.

Cleaning the inner wall of the bathtub with cleaning water simply ejected horizontally from a long hole-like water supply hole along the inner circumference of the bathtub
In the invention of No. 63-97122, the inner peripheral wall of the bathtub located above the location of the water supply hole for cleaning cannot be washed, and the bathtub (2) cannot be washed entirely. On the other hand, according to the above technical means, the cleaning water (W) is jetted obliquely upward from the cleaning shower port (3), so that the cleaning water (W) is jetted at a predetermined jet speed. As a result, the wash water (W) reaches the upper edge of the bathtub (2),
There is an advantage that it can be completely cleaned up to the vicinity of the upper edge.

Since the cleaning water (W) jetted obliquely upward from the cleaning shower port (3) is sprayed over the entire inner peripheral wall of the bathtub (2), the cleaning water (W) is washed by the cleaning shower port (3). It is also sprayed on the inner peripheral wall portion of the bathtub located above the disposition part, so that the cleaning shower port (3) can clean its disposition wall.
