Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath cleaning device.

[0002]

2. Description of the Related Art A bath cleaning device disclosed in Japanese Patent Laid-Open No. 3-70525 is known as a conventional technique according to the present invention. In this bathtub cleaning device, a washing pipe and a detergent pipe each having a water sprinkling hole are arranged around the upper part of the bathtub, and the detergent is discharged from the water spouting hole of the detergent pipe to attach the detergent to the entire wall surface of the bathtub. By discharging the washing water from the washing pipe, the dirt adhering to the inner wall of the bathtub is to be washed off.

[0003]

However, in the above device, the detergent flowing out from the water spray holes of the detergent pipe does not stay on the inner wall of the bathtub due to its weight, but immediately drip down. For this reason, it was not possible to sufficiently bring out the effect of the detergent and remove the dirt adhering to the inner wall.

Therefore, a technical object of the present invention is to provide a bathtub cleaning device for discharging the detergent so that the detergent continues to adhere to the wall surface of the bathtub.

[Constitution of the invention]

[0006]

Means for Solving the Problems To solve the above problems, a technical solution provided by the present invention is a bathtub, a discharge port formed on a wall surface of the bathtub, and a detergent liquid communicating with the discharge port. A bath cleaning apparatus comprising a tank, an exhaust pipe having one end opened to the detergent liquid tank, and an air compressor arranged at the other end of the exhaust pipe.

[0007]

The above technical solution works as follows. That is, air is sent to the detergent liquid tank from the air compressor through the exhaust pipe, the detergent in the detergent liquid tank is whipped into a foam, and the foam-like detergent in the detergent liquid tank is pushed out by the air pressure. , Is discharged from the discharge port on the wall surface of the bathtub. The foamed detergent thus discharged does not drip immediately from the wall surface of the bath tub because the apparent specific gravity becomes light due to the inclusion of air, and can be attached to the wall surface of the bath tub for a long time.

Embodiments of the present invention will be described with reference to FIGS. FIG. 1 is a sectional view schematically showing the configuration of the bath cleaning apparatus 1 of this embodiment. Bathtub unit 2 of bathtub cleaning device 1
Is composed of a bathtub body 3 having a flange portion 3a at its upper end, and a cover portion 4 arranged above the flange portion 3a. A flow path 5 is formed between the flange portion 3 a and the cover portion 4 for passing detergent liquid and washing water. Further, the flange portion 3a and the end portion on the inner peripheral side of the cover portion 4 are arranged with a gap, and the detergent liquid or the rinse water passing through the flow path 5 enters the bath body 3 from this gap, that is, the slit 6. It is designed to be discharged.

A drain port 21 which is opened and closed by a drain valve 22 is formed on the bottom surface of the apparatus body 3. In addition, a water conduit 18 communicating with the flow path 5 is provided on the flange portion 3 a of the device body 3.
The water conduit 18 is connected to a tap water pressure source 20 via a solenoid valve 19. Thus, the solenoid valve 1
When 9 is opened, rinsing water is supplied to the water conduit 18, and the rinsing water flows out from the flow path 5 and the slit 6 and flows down the inner wall of the bath body 3.

Further, one end of a detergent pipe 8 for supplying a detergent liquid is provided so as to project on the side of the flange portion 3a opposite to the water conduit 18, and the detergent liquid tank 10 and the flow path 5 are communicated with each other. There is. At the opening end of the detergent pipe 8, a lid portion 9 that is opened by the pressure of the foamy detergent liquid when the detergent liquid is discharged is provided. A detergent supply pipe 11 is arranged in the detergent liquid tank 10, and a detergent cassette 12 is provided in the detergent supply pipe 11.
Are arranged via a check valve 13. In the present embodiment, the detergent cassette 12 is arranged at a position higher than the detergent liquid tank 10, and the detergent liquid in the detergent cassette 12 moves to the detergent liquid tank 10 without using a pump. Also, the detergent pipe 8 has an air compressor 1
The end of the exhaust pipe 15 connected to No. 4 is inserted. A porous body 16 is arranged at the end of the exhaust pipe 15,
The air sent from the air compressor 14 is made into fine air particles and discharged into the detergent liquid in the detergent pipe 8. A check valve 17 is provided in the exhaust pipe 15 so that the detergent liquid does not flow back from the end of the exhaust pipe 15 to the air compressor 14 side.

The operation of the drain valve 22, the electromagnetic valve 19, the air compressor 14, etc. is controlled by a control unit (not shown) when a switch for instructing the start of cleaning is input. There is. Hereinafter, the operation of this embodiment will be described based on the flowchart of FIG.

First, when a switch for instructing automatic bath cleaning is input in step 30, the drain valve 22 is opened in step 31. As a result, when water or hot water is contained in the bathtub body 3, the water is discharged from the drain port 21. Next, in step 32, the memory N for counting the number of times of cleaning is reset in the control section, and in step 33, the air compressor 14 is turned on. When the air compressor 14 operates, air is discharged into the detergent liquid in the detergent pipe 8 through the exhaust pipe 5 and the porous body 16.
Therefore, the detergent in the detergent pipe 8 is foamed by the suction of air from the porous body 16 and rises in the pipe, pushes up the lid portion 9 and flows out into the flow path 5, and further the slit 6 causes the wall surface of the bath body 3 to rise. run down. At this time, since the detergent is in the form of foam, the apparent specific gravity is small, and the detergent slowly hangs down on the wall surface of the bathtub body 3. Thus, when it is confirmed in step 34 that 3 minutes have passed after the air compressor 14 was turned on, step 35 is executed to turn off the air compressor 14 to stop the outflow of the detergent.

Subsequently, in step 36, the electromagnetic valve 19 is opened, and rinse water is supplied from the tap water pressure source 20 to the flow path 5. The rinse water flows out from the slit 6 and the detergent liquid on the wall surface of the bath body 3 is washed away together with the dirt. At this time,
The lid 9 at the tip of the detergent pipe 8 functions as a check valve so that the rinse water does not flow back from the detergent pipe 8 into the detergent liquid tank 10. When it is confirmed in step 37 that 3 minutes have passed since the solenoid valve 19 was opened, step 38 is executed, and the solenoid valve 19 is closed to stop the outflow of rinse water. In step 39, it is determined whether 3 minutes have passed since the solenoid valve 19 was closed. Wait in this step 39 3
In a minute, the rinse water in the bath body 3 is completely drained from the drain port 21.

Next, at step 40, 1 is added to the memory N for counting the number of washings, and the routine proceeds to step 41. If the memory N is not 3 in step 41, step 33 is executed again to repeat the bath washing,
When the number reaches 3, the bathtub cleaning is completed.

According to this embodiment, since the detergent liquid is foamed by the air compressor 14, the detergent liquid slowly drips down on the wall surface of the bath. Therefore, the detergent liquid can be sufficiently permeated into the dirt adhering to the wall surface of the bathtub, and the dirt can be reliably washed off. In particular, when a detergent liquid containing a stain-degrading component such as protein is used, the detergent liquid does not immediately flow down, so that the stain can be sufficiently decomposed.

In the present embodiment, an example is shown in which one water conduit 18 for rinsing rinse water and one detergent pipe 8 for rinsing detergent liquid are provided in the bath body 3, respectively. The number is not limited, and as shown in FIGS. 4 and 5, there may be a plurality of water conduits 18 and detergent pipes 8. When a plurality of water conduits 18 and detergent pipes 8 are arranged in this way, it becomes possible to more evenly discharge the rinse water and the detergent liquid from the slits 6.

[0017]

According to the present invention, since the apparent specific gravity can be reduced by mixing air into the detergent liquid, the detergent liquid can be sufficiently penetrated into the dirt adhering to the wall surface of the bathtub, and the dirt can be sufficiently washed off. You can
