Description of the Related Art Conventionally, a bathtub is usually cleaned by manually rubbing the wall surface with a sponge or the like, sometimes using a handheld cordless polisher, and then washing the deep part of the bottom of the bathtub. Is also commercially available. However, it is not easy to use because it bends the waist, uses the arms, and requires strength. On the other hand, there is also a system in which the bath water is constantly circulated so as to perform purification and sterilization so that cleaning of the bath is unnecessary.

[0003]

By the way, when cleaning a deep bottom surface of a bathtub, a deep inner bottom surface, or an inner side surface by using a sponge scrubbing brush, a polisher, etc., it is inevitable that the arm is stretched or the waist is bent by hand. It is quite hard work, and the installation cost of the above-mentioned bathtub circulation system is also quite high, and its circulation inlet is located in the upper and lower middle part of the inner surface of the bathtub, and is located on the inner surface of the bathtub near the drinking water line. It is difficult to remove the adhered substances and the slime of the bottom by suction.

Furthermore, in recent years, the shapes and materials of bathtubs have been diversified, and many long bathtubs have been installed, which has increased the cleaning area of the bathtub, making it possible to clean every corner and to further wash the bathtub. It is labor intensive. In addition, a bathtub washer has been proposed in which cleaning is performed by rotating the nozzle unit with wash water that is pumped from the pump, but it cannot be washed automatically depending on the degree of dirt in the bath, and the wash water is wasted. It was easy to use.

The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to automatically wash a bathtub according to the degree of dirt, without requiring labor. To provide a washing machine.

[0006]

A bath cleaning machine according to the present invention comprises:
Washing water is pumped to a nozzle unit 2 by a pump P driven by a motor 17, and the washing water sprayed from the nozzle unit 2 is used to wash the wall surface of the bathtub 3. In the waterway between the unit 2 and the impeller 91 rotated by the wash water passing through the waterway, and after measuring the water quantity by the number of rotations of the impeller 91, the water quantity reaches a preset arbitrary water quantity. An automatic water stop means 93 having a valve 92 for closing the water channel is provided, and the automatic water stop means 93 is provided with a water amount setting dial 95 that is rotated to set the water amount. When the motor 17 is turned on by the rotation operation in the setting direction, the motor 1 is operated when the water amount setting dial 95 returns to the setting zero position.
Motor control means 94 for electrically stopping 7 is provided.

[0007]

The cleaning water pumped from the pump P is sprayed from the nozzle unit 2 to clean the wall surface of the bath 3. The water amount setting dial 95 is rotated to set the water amount of the washing water, and the water amount is set according to the dirt of the bathtub 3 to perform the washing. It is possible to avoid waste of cleaning water when cleaning the bathtub 3. Then, when the water amount setting dial 95 returns to the set zero position, the motor 17 is stopped, and the bathtub 3 is automatically washed even if no person is present.
