Description

Dishwasher and control method

technical field

The invention belongs to the field of household appliances, in particular, to a dishwasher, in particular, to a control method applied to the above dishwasher.

Background technique

Dishwashers in the prior art include a plurality of drawers, but the water intake and drainage of each drawer are individually controlled, and there is no direct connection between the drawers. It will be discharged to the outside, resulting in low utilization of water resources, resulting in a lot of waste of water resources.

Dishwashers have many functions, including multiple washing, rinsing and disinfection. Usually, the last washing water of the dishwasher is relatively clean and the water quality is relatively clear. When a drawer is washed to the final rinsing stage, Direct discharge will cause waste. If the last sequential rinsing water in the drawer can be used as the first washing water in another drawer, the user's water expenditure can be reduced and the user experience can be improved.

The present invention has been made in view of this.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a dishwasher, which discharges the last washing water of a certain dishwashing module to another dishwashing module, so as to realize the repetition of water resources. Utilize, improve the utilization rate of water resources, and save users' water expenses.

In order to solve the above-mentioned technical problems, the basic conception of the technical scheme adopted in the present invention is:

A dishwasher, comprising at least two mutually independent dishwashing modules, each dishwashing module can respectively use water to wash the tableware contained in it; any dishwashing module executes the last washing washing water It flows into another dishwashing module and is used as the initial wash water for the next wash.

Further, each dishwashing module is provided with at least two drainage pipelines, including a first drainage pipeline that is discharged to the outside, and a second drainage pipeline connected to another dishwashing module; the first drainage pipeline is A first drain valve for controlling the on-off of the pipeline is provided, and a second drain valve for controlling the on-off of the pipeline is provided on the second drain pipeline.

Further, the dishwasher is provided with a "water saving washing" function button, after the user presses the "water saving washing" function button, the washing water of the last cleaning of the dishwashing module is automatically discharged to the other dishwashing storage in the module, or cleaning.

The invention also discloses a method for controlling a dishwasher. After the dishwasher selects a dishwashing module to execute a cleaning procedure, the washing water for the last cleaning in the selected dishwashing module automatically flows to another dishwashing module, and then flows into another dishwashing module. The water flow is used as the initial wash water of another dishwashing module for storage or washing use.

Further, after the cleaning procedure of the selected dishwashing module is finished, it is judged whether the user selects the "water-saving washing" function; if so, control the selected dishwashing module to automatically drain water to another dishwashing module; if not, control the Wash water is drained directly to the outside of the dishwasher.

Further, it is determined whether the dishwashing module receiving washing water is in a working state, if so, after the dishwashing module receiving washing water is executed, the washing water for the last cleaning in the selected dishwashing module is received; Set the wash water for the last wash in the dishwashing module.

Further, the washing stage of the dishwashing module of the dishwasher includes the following specific steps:

S1. Determine whether there is water discharged from the selected dishwashing module in the dishwashing module, if yes, go to step S2; if not, go to step S3;

S2. Start cleaning, and then perform step S4;

S3. Inject water into the dishwashing module from the outside, and then perform step S2;

S4. After cleaning, drain water.

Further, after the selected dishwashing module performs the cleaning procedure alone, the last wash water in the selected dishwashing module is discharged into another dishwashing module, and the other dishwashing module can be used as a water storage bucket to store for a certain period of time t; Preferably, the t does not exceed 5 hours; further preferably, when the time exceeds t, an alarm is issued to remind the user, and/or the stored water is directly discharged.

Further, in the initial stage of the dishwasher, there is no washing water in each of the dishwashing modules, and the selected dishwashing module and the dishwashing module receiving the washing water continuously execute the washing procedure in sequence, and the washing stage of the dishwashing module of the dishwasher includes the following specific steps:

S1. Select the dishwashing module to enter the water and execute the cleaning procedure;

S2. the selected dishwashing module cleaning program ends;

S3. Determine whether the dishwasher selects the "water saving washing" function; if yes, go to step S4; if not, go to step S8.

S4. Select the dishwashing module that receives the washing water, and determine whether the dishwashing module that receives the washing water is in a working state, if not, go to step S6; if so, go to step S5;

S5. The execution of the dishwashing module to be received washing water ends;

S6. The washing water in the selected dishwashing module automatically flows to the dishwashing module that receives the washing water, and the inflowing water is used as the initial washing water of the dishwashing module that receives the washing water;

S7. The dishwashing module receiving the washing water uses the washing water discharged from the selected dishwashing module to perform the washing procedure, and after the washing is completed, the water in the dishwashing module is discharged to the outside of the dishwasher;

S8. Drain the wash water in the selected dishwashing module to the outside of the dishwasher.

Further, determine the liquid level height of the water discharged from the selected dishwashing module received by the dishwashing module, stop receiving after the liquid level reaches the set liquid level height, and the remaining washing water in the selected dishwashing module The water is discharged to the outside of the dishwasher; the liquid level is lower than the set liquid level, and all the water in the selected dishwashing module is discharged into the dishwashing module that receives the washing water.

After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

1. The dishwasher in the present invention is provided with at least two mutually independent dishwashing modules. After one dishwashing module is washed, the last washing water in the dishwashing module can be discharged into the other dishwashing module. Used as initial wash water for another dishwashing module. The invention can realize the reuse of water resources, reduce the waste of water resources, and reduce the expenditure on water for users.

2. There is also a "water-saving washing" function button on the dishwasher. Users can choose whether to need "water-saving washing" according to their own needs to improve user experience.

3. In the present invention, after the selected dishwashing module is cleaned, when the last washing water in the dishwashing module is discharged into another dishwashing module, if the dishwashing module that receives the washing water does not perform washing, The washing water can be stored in the dishwashing module for a period of time, which is convenient for the next washing. The storage time cannot be too long to prevent the bacteria in the washing water. When the washing water is stored for this time, the user is reminded to wash or discharge the water.
