It is purchased so that tap water can be supplied by controlling the tap water.

In the case of bath water supply, the theoretical water supply time data stored in the storage means 2 is input to the bath water end detection means 7, and at the same time, the bath water end detection means 7 counts the actual water supply time. If there is no output from the water level detection means 6 even if the actual water supply time matches the theoretical water supply time, the bath water end detection means 7 detects that the bath water has run out, and this information is used to automatically supply water. Information is input into the switching means 8, and information indicating that all subsequent water supply will be supplied with tap water is input into the storage means 2, and all bath water supply data is switched to tap water supply data V, and further control is performed as described above. From now on, tap water is supplied by means 2 (14). Figure 2 is a circuit diagram showing a specific +I + + configuration of this embodiment. 9 is a washing tank 71e; An air trap for water level detection means 6 is provided near the bottom.1
0 is a microcomputer that stores water supply information and generates all signals for driving the tap water supply solenoid valve, bath water supply solenoid valve, and water suction pump according to a built-in program. Specifically, a storage section 10 stores all information such as water supply information and bath water supply time information, and an input section 1 receives the outputs of the switch group 1 and the outputs of the water level detection means 6.
0b, an output section 10C that outputs all control signals to the bath water supply means 4 and tap water supply means 5; an exercise control section 10d that controls all of the storage section 10a1, human power section 10b1, and output section 10C, and performs a data comparison exercise cycle; It is something that you have.

Note that 11 and 12 are a bath water supply solenoid valve and a water suction pump that are turned on and off by the bath water supply means 4, respectively, and 13 is a tap water supply solenoid valve that is turned on and off by the tap water supply means 5.

Next, the operation of this embodiment will be explained. FIG. 3 shows the main part of a flowchart controlled by a microcomputer.

After putting NWA items into the washing tub 9, the user sets all the water supply conditions using the switch group 1, that is, whether to supply bath water or tap water, and starts the washing process. Through this operation, the microcomputer 10 In step 14 switch group 1
The water supply information set by the user is stored.

Next, the microcomputer 10 determines whether the next process is the final rinsing process in step 16, and if it is the final rinsing process, the tap water supply solenoid valve 13 is opened in step 16 to supply tap water. If not, the microcomputer 10 determines whether the water supply information is bath water supply or tap water supply from the storage unit 10a in step 17, and if it is tap water supply, the tap water supply solenoid valve 13 is fully opened in step 18, and step 19 Tap water will be supplied until the set water level is reached. If bath water is to be supplied in step 17, the bath water supply solenoid valve is opened in step 20, and the water suction pump is operated in step 21 to completely supply bath water. At the same time, in step 22, the maximum water supply time for bath water supply is set with a sufficient safety factor based on the water absorption performance of the water suction pump and the size of the washing tub, and the theoretical water supply is stored in the storage unit 10a. Compare the time with the actual water supply time. Here, if the actual water supply time has not reached the predetermined value, water is supplied in step 19 until the set water level is reached. If the bath water runs out during the bath water supply, even if the actual water supply time reaches the theoretical water supply time limit, the set water level is not reached, and in step 22 it is detected that the bath water has run out, and then, In step 23, the bath water supply solenoid valve 11 is closed, in step 24, the water suction pump is stopped, and in step 26, all subsequent water supply is switched to tap water supply, the record is re-stored in the first part 10a, and the step is repeated. Return to step 17 and repeat the above operations.

Next, in FIG. 4, an air trap 26 for pressure casing inch 2 is provided in the middle of the bath water supply channel between the other implementation valves 11 of the bath water end detection means, and a pressure casing inlet 27 is provided in the middle of the bath water supply.
The bath water end detecting means is provided to determine that the bath water has run out when the switch is switched from the closed side to the open side. By using the bath water end detection means as described above, the water suction pump will stop the moment the bath water runs out, and the dry running time will be significantly shorter than in the previous embodiment, improving the durability of the water suction pump. This also reduces washing time and contributes to energy savings.

Effects of the Invention As described above, according to the present invention, the user can freely set the water supply for bath water and tap water during rinses other than the first rinse and the final rinse, and the tap water is always turned on during the final rinse step. It can supply water, and when the bath water is supplied, it automatically switches to tap water supply as soon as the bath water runs out, so the user can reuse the bath water to the maximum extent according to his/her preference, and wash all the bath water ( In other words, the present invention can improve the water saving effect and completely automate the water supply/stem using a water suction pump.
