The operation of the bathtub cleaning apparatus according to this embodiment will be described with reference to FIG. When the cleaning start button of the bath cleaning device (not shown) is operated when the bath 200 is empty,
The hot and cold water open / close valve 7 is opened for a short time and then closed based on a command from the control device. Hot and cold water pumped from a hot and cold water supply source (not shown) through the branch fitting 300 and the soft hose 2 flows into the cleaning liquid generator 1 through the inlet port 5, reaches the detergent mixing section 11 through the pipe line, and exits. It flows out of the cleaning liquid generator 1 through the port 21. The hot water reaches the cleaning nozzle 4 through the soft hose 3 and is jetted from the cleaning nozzle 4 for a short time. A person in the bathroom unit 100 is warned of the start of bathtub washing by jetting hot water for a short time ((1) in FIG. 12). Even if hot water enters the eyes of a person in the bathroom unit 100, it is safe because the hot water does not contain a detergent. A float (not shown) comes into contact with the atmosphere opening port due to the water pressure of the hot water flowing through the pipe of the cleaning liquid generating apparatus 1 to close the atmosphere opening valve 8, and the water pressure of the hot water flowing through the pipe resists the biasing force of the spring 9d to prevent the ball 9c. Is pressed against the O-ring 9a to close the lifting valve 9, and the intake valve 6 is normally closed, so that hot water does not leak from the pipe of the cleaning liquid generator 1.

After a lapse of a predetermined time from the hot water injection, the pump 15 operates for a predetermined time and then stops according to a command from the control device. The detergent in the detergent tank 12 is pressure-fed to the detergent mixing section 11. Detergent is mixed with hot water accumulated in the detergent mixing section 11 to generate a cleaning liquid in the detergent mixing section 11 (see FIG. 1).
2 (2)). Since the detergent is mixed in the hot and cold water that stays in the detergent mixing section 11, even if the water pressure of the hot and cold water supplied to the cleaning fluid generation device 1 varies, it is possible to constantly generate the desired concentration of the cleaning fluid. In response to a command from the control device, the hot and cold water open / close valve 7 is opened, and the cleaning liquid in the detergent mixing section 11 is flow rate adjusted valve 20
After being adjusted to an appropriate flow rate through the cleaning hose 3, it is pressure-fed to the cleaning nozzle 4 through the soft hose 3, ejected from the cleaning nozzle 4 and adheres to the inner surface of the bath. Dirt adhering to the inner surface of the bath dissolves in the cleaning liquid. Only hot and cold water is jetted continuously after jetting the washing liquid to wash away the washing liquid in which dirt is dissolved, and then the hot and cold water opening / closing valve 7 is closed ((3) in FIG. 12). With the above, the initial cleaning of the inner surface of the bath is completed. By the initial washing, dust such as hair adhering to the inner surface of the bath can be washed off before the main washing. Further, it is possible to easily remove dirt such as water stains attached to the inner surface of the bathtub.

According to a command from the control device, the pump 15 operates for a predetermined time and then stops. The detergent in the detergent tank 12 is pressure-fed to the detergent mixing section 11. Detergent is mixed with hot water that accumulates in the detergent mixing unit 11, and a cleaning liquid is generated in the detergent mixing unit 11 ((4) in FIG. 12). According to a command from the control device, the hot and cold water opening / closing valve 7 is opened for a predetermined time and then closed. The cleaning liquid in the detergent mixing section 11 is pressure-fed to just before the cleaning nozzle 4 ((5) in FIG. 12). After a lapse of a predetermined time, the hot and cold water open / close valve 7 is opened again for a predetermined time and then closed. The entire amount of the cleaning liquid existing in front of the cleaning nozzle 4 is jetted ((6) in FIG. 12). As a result, the cleaning liquid adheres to the inner surface of the bath. Since only the lump of the cleaning liquid existing in front of the cleaning nozzle is sprayed, the cleaning liquid adheres to the inner surface of the bath without being diluted with hot water. As a result, the cleaning action of the cleaning liquid is sufficiently exerted. Dirt on the inner surface of the bath, which was easily removed by the initial cleaning, easily dissolves in the cleaning liquid.

In response to a command from the control device, (4) to (4) in FIG.
The step (6) is repeated a plurality of times. As a result, the steps of spraying the cleaning liquid, waiting for a predetermined time, spraying hot and cold water, and waiting for a predetermined time are repeated a plurality of times, and the dirt adhering to the inner surface of the bath is sufficiently washed off. Since there is a predetermined waiting time between the injection of the cleaning liquid and the injection of hot water, the cleaning liquid adhering to the inner surface of the bath stays on the inner surface of the bath without being washed away for the predetermined time. As a result, the stain dissolving action of the cleaning liquid is sufficiently exerted. By repeating the process of spraying the cleaning liquid, waiting for a predetermined time, spraying hot water only and waiting for a predetermined time a plurality of times, the cleaning effect is enhanced and the waste of the detergent is suppressed. According to a command from the control device, the hot and cold water opening / closing valve 7 is opened for a predetermined time and then closed. Only hot water is jetted from the cleaning nozzle 4 for a predetermined time ((7) in FIG. 12), the bath 100 is rinsed and the bath cleaning is completed.

When a negative pressure is generated in the conduit of the cleaning liquid generator 1, the negative pressure applied to the ball 6c resists the urging force of the spring 6d to separate the ball 6c from the O-ring 6a and open the intake valve 6. The float (not shown) separates from the atmosphere opening port to open the atmosphere opening valve 8, and the negative pressure applied to the ball 9c and the biasing force of the spring 9d cause the ball 9c to separate from the O-ring 9a to open the lift valve 9. As a result, air is sucked into the pipeline of the cleaning liquid generation apparatus 1 from the intake valve 6, the atmosphere release valve 8 and the elevation valve 9, and hot water is discharged from the pipeline of the cleaning liquid generation apparatus 1 through the elevation valve 9. The hot and cold water discharged from the lower end of the lift valve 9 flows into the drainage receiving member 23, passes through the drainage hose 24, and is discharged from the drainage hose 24 near the bath drainage port 200a. The hot water discharged from the drain hose 24 flows into the drain trap under the floor pan through the drain recess of the floor pan directly below the bath drain 200a and the connecting pipe, and is discharged from the drain trap to the outside of the bathroom. When the bath water is accumulated in the bath 200 beyond the height position of the cleaning nozzle 4, a negative pressure is generated upstream of the cleaning liquid generator 1 due to water interruption or the like, and the closing operation of the hot and cold water opening / closing valve 7 is not correct. However, the check valve 10 operates to prevent the backflow of bath water upstream of the cleaning liquid generator 1. Even if the operation of the check valve 10 fails, the cleaning liquid generation device is constructed by sucking air from the intake valve 6, the atmosphere opening valve 8, and the lifting valve 9 and discharging the air from the lifting valve 9. The backflow of bath water to the upstream of 1 is prevented.
Since the lift valve 9 is disposed below the hot water opening / closing valve 7, the hot water in the conduit between the hot water opening / closing valve 7 and the lift valve 9 is drained from the hot lifting water opening / closing valve 9 An air gap is formed between 7 and the lifting valve 9. As a result, perfect backflow prevention is achieved. Intake valve 6, atmosphere release valve 8,
If any one of the raising and lowering valves 9 operates perfectly, the backflow of bath water to the upstream of the cleaning liquid generator 1 is blocked. By extending the drain hose 24, one end of which is connected to the drain receiving member 23, to the vicinity of the bath drain 200a, and flowing hot water discharged from the drain hose 24 into the drain recess of the floor pan immediately below the bath drain 200a, The floor pan is prevented from becoming dirty. By opening the lower end of the lift valve 9 to the atmosphere, malfunction of the lift valve 9 when the drain hose 24 is clogged and backflow of hot water from the drain hose 24 to the lift valve 9 are prevented.

Since the cleaning liquid generator 1, which is the main part of the bath cleaning device, is attached to the bathroom side wall 102, it does not submerge in the bath water. The cleaning liquid generation device 1 includes a bath 200.
Since it is surrounded by the rim 201, the apron 202, and the bathroom side wall 102, the bath water is not splashed. Therefore, hair and dirt do not adhere to the cleaning liquid generator 1, which is the main part, and the bath cleaning device according to this embodiment is sanitary. Since the cleaning liquid generator 1 does not submerge in the bath water and it is not necessary to waterproof the electric parts, the structure does not become complicated. Since the structure of the wash water generator 1, which is the main part, is not complicated, the structure of the bath cleaning device according to the present embodiment is not complicated. Since the cleaning liquid generator 1, which is the main part, is located outside the bathtub, the bath cleaning device according to this embodiment does not disturb the bather. Since the cleaning liquid generator 1, which is the main part, does not catch the eyes of the bathroom user, the bath cleaning device according to this embodiment does not impair the aesthetics of the bathroom unit 100.

A plurality of openings 22a formed in the support fitting 22
