In addition, the fixing plate 202 is disposed adjacent to the connecting seat 201 to shorten the connecting distance between the water pump 18 and the water path on-off valve 19, thereby effectively improving the compactness of each component, further reducing the occupied space and reducing the volume of the whole machine.

Referring to fig. 12, the operation principle of the dishwasher according to the embodiment of the present application is as follows:

firstly, the dish-washing machine comprises two water inlet modes of water tank inlet and tap water inlet, and the water inlet function mode simultaneously exists. The water inlet mode of the waterway is as follows:

path: the dishwasher directly cleans tableware, and water is not stored in a water tank, so that the water tank only serves as a standby function;

path II: manual filler 62 is used to the storage water tank, when inconvenient connection running water halter or running water cut off water in the user family, manual through filler 62 toward the water tank in injected water and fill up, when the machine washs the tableware, obtain the washing water through the storage water tank: a water storage tank, a water pump, a water pipe, a flowmeter, a water inlet anti-siphon, a water pipe, a water softener, a water pipe and a washing cavity;

the water softener and the corresponding water pipe are optional and can be selected according to different requirements for use, that is, the water softener and the matched water pipe are not required in the path, but the configuration is required.

Secondly, the control modes of two water inlet modes of water tank inlet and tap water inlet of the dish-washing machine are as follows:

after the user selects the washing program and presses the start key:

1, T value of 1(T value represents path selection times after water inlet failure)

2. Starting a water inlet waterway mode of the water inlet valve;

3. judging whether the flowmeter sends out a pulse total value larger than a set minimum pulse value to a main control board control circuit within a set time;

4. if the pulse total value is larger than the minimum pulse total value, judging that the tap water is normal, and continuously feeding water in a first mode until the pulse value fed back by the flowmeter corresponding to the single water feeding value set by the program corresponding to the washing program selected by the user is finished;

5. stopping water inflow, spraying and cleaning the tableware, and recording a water inflow path A (currently, recording the water inflow path A as phi).

6. When the flow meter in the step 2 is not in the set time, sending a total pulse value larger than the set minimum pulse value to the control circuit of the main control board;

7. if the pulse sum is less than the minimum pulse sum value, judging that the tap water fails to enter water, starting water inlet according to a second mode, and starting a water pump to pump the cleaning water in the water tank; and T ═ T +1

8. Judging whether the flowmeter sends out a pulse total value larger than a set minimum pulse value to a main control board control circuit within a set time;

9. if the pulse value is larger than the minimum pulse total value, the water tank is judged to contain washing water, the water tank is filled with water normally, and water is filled continuously according to the second mode until the pulse value fed back by the flowmeter corresponding to the single water inlet value set by the program corresponding to the washing program selected by the user is finished;

10. stopping water inflow, spraying and cleaning the tableware, and recording a water inflow path A (currently, recording that the water inflow path A is two). And resetting the value of T, T being 1

Wherein: the water inlet times of each user washing program are different, and the difference of water inlet 2 times and water inlet 3 times or water inlet 4 times exists. Namely, the washing program selected by the user is completed, and water is fed for many times in the middle.

11. When a user program runs halfway and needs to carry out water inlet for N +1 times on a washing cavity, the recorded water inlet path A value is preferentially selected for water inlet;

12. judging whether the flowmeter sends out a pulse total value larger than a set minimum pulse value to a main control board control circuit within a set time;

13. if the pulse total value is larger than the minimum pulse total value, judging that the water inflow is normal under the current condition, and continuously feeding water in a mode (the current path A value) until the pulse value fed back by the flowmeter corresponding to the single water inflow value set by the program corresponding to the washing program selected by the user is finished;

14. if the current water inlet path is smaller than the minimum pulse total value, judging that the water inlet fails under the current condition, switching another water inlet path of the current path, assigning a value to the current path A, and if the current water inlet path is phi, switching to phi and reassigning the current path A)

15. Judging whether the flowmeter sends out a pulse total value larger than a set minimum pulse value to a main control board control circuit within a set time;

16. if the water content is larger than the preset value, water is fed to the reaction kettle until the reaction is finished. If less than, the step 14 is returned. And when the T value is greater than 3, prompting alarm information and feeding back water shortage.

By the mode, tap water does not need to pass through the built-in water tank, the water inlet time is effectively shortened, the machine runs in a short time, and water flow is sprayed to clean tableware. The machine is whole, and the reaction is sensitive and response speed is fast, promotes user's use and experiences, improves user's purchase desire.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
