摘要： PROBLEM TO BE SOLVED: To improve combustion of a burner combustor by using a NOX sensor. SOLUTION: A NOX sensor 23 is provided on the exhaust side of the burner combustor. A memory 19 stores data on reference concentration of NOX for carrying out a combustion improvement. During a combustion operation, a comparing part 21 makes comparison between a NOX concentration detected by the sensor 23 and the reference concentration stored in the memory 19. When the detected concentration is higher than the reference concentration, a command for raising air flow rate is issued to a fan rotation controller 22, which, on receiving the command, controls the rotation of a combustion fan 5 in the direction for raising the air-flow rate. An air flow insufficiency caused by stopping up of exhaust is eliminated, and NOX generation is restrained to attain a clean combustion of less NOX emission.

CONSTITUTION:A nozzle 6 rotating with water pressure is mounted at the center of the inner surface of a lid 5, and when bathing is finished and the lid 5 is set correctly, the service water is spouted from the nozzle 6 to bring away the dirt, etc. Detergent solution is injected into a buffer 2 from a vessel 8, and No.1 three-way valve 19 is changed over to the heating device side. Heating is maintained, and the washing water is spouted from the nozzle 6 into the bathtub 1 to perform washing. Then, circulation is made by a circulating pump 16 following the route as the nozzle 6, bathtub 1, buffer 2, a circulation hole 2' for returning, (heating device 11), circulating pump 16, No.1 three- way valve 19, No.2 three-way valve 19', and again the nozzle 6. Thus, the insides of the bathtub 1, buffer 2, and circuit of circuilating pump 16 are filled with the detergent solution, followed by flushing away with clean water.

摘要： PURPOSE:To automatically and uniformly wash a bathtub by spraying a detergent into a bathtub by connecting a supply means of compressed air to a fine spray nozzle, and also, injecting water by a water injection nozzle and washing away dirt on a bathtub inner wall together with the detergent. CONSTITUTION:When an air compressor 14 is actuated, a detergent is sucked to a fine spray nozzle 4 from a detergent tank 21, injected into a bathtub 1, infiltrates into an inner wall 3 of the bathtub 1, and an easily washable state is obtained. On the other hand, a water injection nozzle 5 is provided so as to be opposed to the inner wall 3 on which the fine spray nozzle 4 is provided projectingly, and also, the longitudinal direction of a notch 18 is aligned with the horizontal direction, and since the injecting direction is directed to about the center part of a bathtub cover 22, water becomes an injection flow of high pressure in an injection port 20, is scattered and injected along a shape of the notch 18, and scattered toward about the center part of the bathtub cover 22. The other water injection nozzle 5 spreads efficiently over the whole surface of the inner wall 3 of the bathtub 1 and the bathtub cover 22 since water is injected by switching a changeover valve 17. As a result, the dirt on the inner wall 3 of the bathtub 1, the remainder of the detergent and hair, etc., are washed away.

摘要： PURPOSE:To wash away the dirt adhering to a bathtub wall by spraying finely a detergent into a bathtub, exhausting a small quantity of water after it is left as it is and forming a thin film of the detergent on the inner wall of the bathtub, and subsequently, diluting the thin film and allowing it to flow out by injecting water, and thereafter, injecting water into the bathtub. CONSTITUTION:After a bathtub is closed by a bathtub cover 18, a detergent is sucked to a fine spray nozzle 4 through a detergent selection valve 11, a detergent supply pipe 9 and a water/detergent supply pipe 12 from a detergent tank 17, becomes a fine spray in the bathtub and a small quantity thereof is injected for a prescribed time. After it is left as it is for a prescribed time, the water selection valve 10 is opened, water is supplied to the fine spray nozzle 4 through a water supply pipe 8 and the water/detergent supply pipe 12, and by injecting a small quantity thereof into the bathtub for a short time, a thin film of the detergent is formed on the whole surface of a bathtub inner wall 3, and it is infiltrated into the dirt adhering to the inner wall. Subsequently, when water is injected into the bathtub from the fine spray nozzle 4, the thin film of the detergent formed on the bathtub inner wall is mixed with water, and diluted and fluidized gradually. Thereafter, when water is injected into the bathtub from a water injection nozzle 5, the dirt on the bathtub inner wall is washed away, and discharged from a discharge water valve 20.
