Abstract

PURPOSE:To surely throw in a detergent of a prescribed quantity to a detergent throwing-in part at the time of washing a bathtub. CONSTITUTION:A going tube 8 of a bathtub washing device connects a detergent tank 17 through a detergent throwing-in valve 42 and a detergent flow sensor 41. In the detergent tank 17, a liquid detergent is contained, and the detergent flow sensor 41 is constituted by containing a float 44 so as to be freely slidable vertically in a sliding case 43. In the float 44, a magnet is provided, and on the peripheral wall surface of the sliding case 43, a read switch for outputting a turn-on signal by being opposed to the magnet at the time when the float 44 is in the sliding lower limit position, and outputting a turn-off signal at the time when the float 44 ascends to the sliding upper limit position by buoyancy of the detergent is provided. A controller 31 discriminates and decides a run-out state of the detergent and a normal throwing-in operation state of the detergent, based on a signal from the read switch and an operation state of the detergent throwing-in valve 42, and executes a notice of replenishment of the detergent to a detergent replenishment display part 34 of remote control 32 at the time of run-out of the detergent.

However, when the detergent is supplied from the detergent tank to the cleaning liquid circulating pipe, when the opening / closing valve for the detergent introduction is opened to perform the detergent introduction operation, the detergent is normally introduced or the detergent runs out. There is an inconvenience that it is not possible to automatically detect the state such as whether or not there is. For this reason, there is a problem that the bathtub washing operation is performed without the detergent without noticing that the detergent has run out.
When installing the equipment and performing the cleaning operation for the first time, etc.,
The pipeline from the detergent tank to the detergent inlet is filled with air, and even if the detergent inlet opening / closing valve is opened for a certain time and the detergent is dropped into the pipeline to the inlet, this detergent will not reach the inlet. There was a problem that the cleaning operation was carried out with the cleaning liquid containing only the water that did not reach the cleaning agent and did not reach.

Next, the detergent loading operation is performed from steps 106 to 117. First, as shown in FIG.
At 106, it is determined whether the detergent flow sensor 41 outputs an ON signal. When the ON signal is output, it is determined that the float 44 is at the sliding lower limit position due to its own weight and the sliding case 43 is not filled with the detergent. Whether the detergent is completely empty in steps 107 to 109 or the detergent is contained in the detergent tank 17 but the air is accumulated in the sliding case 43 and the detergent does not enter. Make a decision. That is,
Open the detergent valve 42 only T a seconds close the detergent valve 42 from in step 107. Then, when the detergent tank 17 is filled with the detergent, the detergent enters the sliding case 43. Therefore, by closing the detergent input valve 42 next time, the float 44 is lifted by the buoyancy and turned off from the reed switch 46. A signal is output, and by confirming that this OFF signal is output, the detergent is not running out, and step 11

On the other hand, when an ON signal is output from the detergent flow sensor 41 in step 112, the detergent injection valve 42
By the opening operation of the detergent, the detergent flows from the detergent tank 17 side to the detergent input valve 42 side, and the float 44 is caused by the detergent flow.
Is in the sliding lower limit position, that is, it is judged that the detergent has been normally charged, and in step 113, the detergent charging valve 42 is closed after the detergent has been charged for T b seconds. Then, in step 114, the detergent flow sensor
It is judged whether the OFF signal is output from 41, and it is confirmed again whether the detergent has run out. Detergent flow sensor
When the ON signal is output from 41, the float 44 moves to the sliding lower limit position by its own weight, and it is judged that the detergent has run out. In step 115, the detergent replenishment display is performed as in the case of step 110. When the OFF signal is output from the detergent flow sensor 41, it is determined that the inside of the sliding case 43 is filled with the detergent and the detergent is not run out, and the step 11
At 6 it is judged whether the opening / closing operation of the detergent injection valve 42 has been performed N times (N is an integer of 1 or more), and when the opening / closing operation of the detergent injection valve does not reach N times, the detergent injection from steps 111 to 116 is performed. When the detergent input valve 42 is opened and closed N times by repeating the operation, a predetermined amount of detergent (the detergent input valve 1
It is determined that, for example, 30 cc of detergent has been dispensed to the outward pipe 8 side, and the detergent dispensing operation is terminated.

Next, the cleaning operation from steps 118 to 157 will be described. In this cleaning operation, first, step 118
From 120 to 120, the operation of accumulating the minimum amount of cleaning liquid necessary for the normal operation of the circulation pump 6 on the bottom side of the bath 1 is performed. That is, the pouring valve 12 is opened and the hot water on the side of the hot water supply device 13 is reheated and supplied into the circulation pipeline, and this hot water is washed by the cleaning nozzles 2a, 2
b and the return branch pipe 4 from the side into the bathtub 1. As a result, the cleaning liquid in which the detergent and the hot water are mixed is stored on the bottom surface side of the bathtub 1. The amount of hot water dropped from the water heater 13 into the bathtub 1 is obtained by cumulative calculation of the detected flow rate obtained from the flow rate sensor 25, and when the cumulative calculated value reaches a predetermined value of X 1 liter, the minimum required cleaning liquid. Is determined to have been stored in the bathtub 1, and the pouring valve 12 is closed.

Next, in steps 138 to 141, the washing nozzle 2b cleans the inner wall surface of the bathtub with hot water. For this hot water washing, the return pipe on-off valve 20 is closed and the pouring valve 12 is opened to guide the hot water on the side of the water heater 13 to the washing nozzle 2b while washing the inside of the pipe from the outgoing pipe 8 side, and from this washing nozzle 2b to the wall surface of the bathtub. It is performed by jetting. By this hot water injection, the cleaning liquid adhering to the inner wall surface of the bathtub and the dirt component removed by the cleaning liquid are washed away and discharged from the drain pipe 18. After the hot water is jetted from the washing nozzle 2b for a predetermined time,
From 142 to 145, the hot water on the side of the hot water supply device 13 is supplied to the washing nozzle 2a from the forward pipe 8 and the washing of the inner wall surface of the bathtub by the washing nozzle 2a is performed in the same manner. After washing the inner wall surface of the bathtub with this washing nozzle 2a,
The return branch pipe 4 is washed with hot water from 146 to 151. This hot water washing is performed by dropping the hot water on the side of the water heater 13 from the return pipe 5 through the return branch pipe 4 into the bath and draining it from the drain pipe 18. After the hot water cleaning of the return branch pipe 4 is performed for a predetermined time, the hot water of the water heater 13 side is passed through the return branch pipe 3 to wash the hot water of the return branch pipe 3 in the same manner from steps 152 to 156. .. After the hot water washing of the return branch pipe 3 is completed, the drain valve 19 is closed in step 157 and the bath washing operation is completed.
