- the turbidity detection unit 14 it is possible to secure an appropriate distance necessary for turbidity detection by the turbidity detection unit 14. Therefore, it is possible to satisfy both of ensuring the drainage capacity by widening the cross-sectional area of the drainage path 12 and ensuring the detection accuracy of the turbidity detection unit 14.
- the water supply device 3 is opened and water supply is started.
- the water supply device 3 is closed to complete the water supply.
- the motor for driving the pump 5 is not rotating, and the switching valve 8 is in a state where the drain side pipe 6b is not closed. Therefore, the cleaning water reaches the drainage path 12 communicating with the water storage part 2 a of the cleaning tank 2 through the inside of the pump 5. Then, the flush water is also filled in the drainage path 12 and the convex portion 15 at the position of the turbidity detection unit 14.
- the switching valve 8 When the cleaning process is started, the switching valve 8 is closed on the drain side by the flow of the cleaning water, and the cleaning water does not enter the drain side. Therefore, in this state, it is impossible to detect the contamination of the cleaning water in the cleaning tank 2 while the initial cleaning water is confined in the drainage path 12.
- the drain pump 5b When the cleaning process is completed and the contamination of the cleaning water in the cleaning tank 2 is detected, the drain pump 5b is operated for a short time and then stopped. Thereby, the dirty cleaning water in the cleaning tank 2 is allowed to enter the vicinity of the convex portion 15, which is a drainage path portion facing the turbidity detection unit 14, and the turbidity of the cleaning water can be measured. At this time, the vicinity of the convex portion 15 facing the turbidity detection portion 14 is already filled with the initial washing water from the time when the water supply is completed. Therefore, there is almost no discontinuous movement or disturbed movement of the washing water, and turbidity can be detected in a stable state.
- control unit 13 changes the operating conditions of the cleaning pump 5a, the heater 10, the water supply device 3, or the drainage pump 5b, for example, by changing the number of times of rinsing. Thereafter, a process such as rinsing and drying is performed, and the operation is terminated.
- FIG. 6 is a flowchart showing an initial setting sequence for turbidity detection according to the embodiment of the present invention.

- the value is used as a reference value.
- the turbidity detection unit 14 detects the permeability (turbidity) of the cleaning water discharged after the cleaning is completed, and based on the amount of change from the reference value, how dirty the drainage is, that is, cleaning.
- the degree of soiling of the tableware cleaned in the tank 2 is determined by quantification.
- the control part 13 performs each process of the rinse after a washing
- the permeability detected by the turbidity detection unit 14 has a characteristic that the state with water is higher than the state without water. However, when the washing water of the turbidity detection unit 14 is dirty after the water supply is finished, the permeability is lower than that in the absence of water even in the presence of water.
- the turbidity detection unit 14 is an optical sensor provided with the light emitting unit 14a and the light receiving unit 14b facing each other.
- the dishwasher 50 emits light in the absence of water after starting operation (step S1), before draining or after draining (in FIG. 6, the case after draining (step S2) is described).
- a predetermined initial voltage value is supplied to the unit 14a, and the received light voltage T1 of the first transmittance is detected by the light receiving unit 14b of the turbidity detecting unit 14 provided in the middle of the drainage path 12 (step S3).
- step S4 a water supply process is performed (step S4), and in the state where there is water thereafter, the same voltage value is supplied to the light emitting unit 14a, and the received light voltage T2 having the second transmittance is received by the light receiving unit of the turbidity detecting unit 14. 14b (step S5).
- the control unit 13 compares T1 and T2 (step S6). If T2> T1, it is determined that the initial water is not contaminated, and the second transmittance (light reception voltage T2) is adopted as the reference value. (Step S7).
- the voltage supplied to the light emitting unit 14a is adjusted so that the light receiving voltage T2 of the light receiving unit 14b of the turbidity detecting unit 14 becomes a predetermined reference voltage value (step S8).
- the reference voltage value is used to correct the turbidity of the washing water in order to correct the transmissivity of the side surface 15c of the convex portion 15, the individual difference between the light emitting portion 14a and the light receiving portion 14b, and the influence of aging. This is set as a reference value (reference value of received light voltage) for the degree of information, and is not necessarily limited to this method.
- the process up to step S7 may be executed.
- the control unit 13 controls to use the reference value at the previous operation without using the second transmittance (light reception voltage T2) as the reference value as described above. (Step S9). That is, the control unit 13 performs control such as using the voltage value supplied to the light emitting unit 14a during the previous operation.
- any before the drainage at the time of an operation start and after drainage may be sufficient.
- water is not present in the turbidity detector 14 and there is no water.
- the turbidity detection unit 14 is in a waterless state. Therefore, by detecting before draining or after draining at the start of operation, the transmittance in the absence of water can be detected in any case.
- the pump 5 is described as a cleaning / drainage pump that functions as two types of pumps, the cleaning pump 5a and the drainage pump 5b, by changing the rotation direction of the motor.
- the switching valve 8 may be operated by a driving device to switch the flow of cleaning water to the cleaning side pipe 6a or the drainage side pipe 6b, and function as two types of pumps in one rotation direction.
- the pump 5 with the switching valve 8 has been described.
- the dishwasher 50 of the present embodiment in the initial setting sequence of turbidity detection, when detecting the permeability of the initial water after water supply serving as the reference value, the drainage path at the start of operation.
- the turbidity detection unit 14 provided in the middle of No. 12 is caused to detect the transmittance in the absence of water. Then, the permeability in the absence of water and the permeability in the presence of water after water supply are compared. If the permeability in the presence of water is greater than the permeability in the absence of water, Use the value as the reference value. On the other hand, when the value of the permeability in the presence of water is equal to or less than the value of the permeability in the absence of water, the value is not adjusted to the reference value, and the reference value from the previous operation is used.
- the dishwasher that detects the turbidity of the washing water by the turbidity detection unit provided in the middle of the drainage path, a large amount of dirt is introduced into the washing tank, and after the water supply is completed. Even when dirty water arrives at the turbidity detection unit, it is possible to determine the correct degree of contamination, and it is possible to perform cleaning according to the contamination of the object to be cleaned appropriately. Therefore, this invention is useful as a dishwasher etc. which wash
