In order to solve the problem that the washing effect of the existing dishwasher is affected by too much residues in the washing process, the dishwasher of the invention comprises an inner container 4, a washing device 2, a drainage device 3 and a residue crushing device 1 (as shown in figure 1), wherein an inlet of the residue crushing device 1 is communicated with the bottom of the inner container 4, a first outlet of the residue crushing device 1 is communicated with the washing device 2 through a first valve, preferably, a filter screen is arranged at a first outlet of the residue crushing device 1, the filter screen can prevent the residues in the washing process from entering the washing device 2, and a second outlet of the residue crushing device 1 is communicated with the drainage device 3 through a second valve. The washing device 2 comprises a circulating pump arranged outside the inner container 4 and a spraying device arranged inside the inner container 4, the circulating pump is connected with the spraying device through a circulating pipeline, and a flow velocity sensor is arranged in the circulating pipeline.
As shown in fig. 2, the control method of the dishwasher of the present invention includes the steps of:
step S100: controlling the washing device 2 to operate and executing a spraying mode;
step S200: detecting the water flow speed in a spraying mode;
step S300: the operation mode of the dishwasher is selected according to the water flow rate.
After water enters the dishwasher to a sufficient amount, the washing device 2 is started and the spraying mode is executed, the flow velocity sensor is arranged in the circulating pipeline, in addition, in order to enable the flow velocity sensor to better detect the water velocity of the residue smashing device 1 entering the washing device 2, the flow velocity sensor is arranged on the pipeline between the residue smashing device 1 and the washing device 2, so that the water velocity of the circulating pipeline under the spraying mode can be detected in real time, when residues in the residue smashing device 1 are excessive, the water outlet of the first outlet of the residue smashing device 1 is influenced by the residues to reduce the water velocity entering the circulating pipeline, when the water velocity is reduced below the preset velocity, the content of the residues is proved to be excessive, the water velocity in the circulating pipeline is reduced, the spraying speed of the spraying device is reduced or the spraying water quantity is reduced, the spraying mode is required to be stopped for smashing treatment, and the phenomenon that the spraying device is blocked by the residues to influence the washing effect is avoided.
As shown in fig. 3, the control method for detecting the water flow speed of the dishwasher specifically comprises the following steps:
step S100: controlling the washing device 2 to operate and executing a spraying mode;
step S200: detecting the water flow speed in a spraying mode;
step S310: judging whether the water flow speed is lower than a preset speed or not;
step S3101: when the water flow speed is lower than the preset speed, closing the washing device 2 and the first valve, and ending the spraying mode;
step S410: starting the residue crushing device 1 and executing a residue processing mode for T time;
step S3102: when the water flow speed is greater than or equal to the preset speed, step S100 is executed.
Comparing the water flow speed with a preset speed, and when the water flow speed is greater than or equal to the preset speed, proving that the content of residues in the water flow flowing into the circulating pipeline from the residue smashing device 1 is low, so that the content of the residues in the residue smashing device 1 can be judged to be low; when water velocity is less than and predetermines the speed, can conclude that rivers in the circulating line receive the influence of residue great and lead to the rivers velocity in the circulating line slower, thereby avoid at this moment the too high rivers of residue content to flow into spray set in thereby block up spray set, and then influence the washing effect, need carry out shredding to the residue.
The preset speed can be set according to the needs of those skilled in the art, can be set according to the use habits of the user, and can be calculated through experiments. For example, the water flow rate of the dishwasher in the normal case is experimentally measured, and the preset rate may be set to be lower than 20% of the water flow rate at this time, and when the water flow rate in the spray mode is lower than 20% of the water flow rate in the normal case, that is, lower than the preset rate, the residue pulverizing device 1 is activated and the residue treatment mode is performed. Of course, the preset speed is not limited to the above-described setting.
Furthermore, although it is described in step S3102 that the washing apparatus 2 is controlled to continue to perform the spray mode when the water flow speed is equal to or greater than the preset speed, this is not restrictive, since the preset speed is a critical value, and therefore, it may be defined in step S3101, and at this time, when it is detected that the water flow speed is equal to the preset speed, the operation of closing the washing apparatus 2 and the first valve in step S3101 and ending the spray mode is performed, and the above adjustment does not depart from the principle of the present invention, and thus, will fall within the protection scope of the present invention.
As shown in fig. 4, when the water flow speed is less than the preset speed, the dishwasher needs to crush the residue, and the control method of the dishwasher at this time specifically includes the following steps:
step S3101: when the water flow speed is lower than the preset speed, closing the washing device 2 and the first valve, and ending the spraying mode;
step S410: starting the residue crushing device 1 and executing a residue processing mode for T time;

step S440: after the drain mode is performed for a time T2, the second valve and the drain 3 are closed, wherein T2> T1.
When the water flow speed is less than the preset speed, the spraying mode is finished and residue crushing treatment is carried out for T time, the crushed residue needs to be discharged out of the dishwasher, drainage treatment for T1 time is carried out at the moment, in the residue discharging process, the residue at the bottom possibly does not remain in the residue crushing device 1 along with the sewage discharged out of the dishwasher, therefore, after the drainage mode is carried out for a period of time, namely T1, the washing device 2 needs to be started to spray in the dishwasher, because the drainage device 3 is still running, the residual residue in the residue crushing device 1 is discharged through the drainage device 3 while being sprayed and washed. It should be noted that before the washing device 2 is opened to spray, it is generally detected whether the water in the water storage tank is sufficient, when the water in the water storage tank is sufficient, the washing device 2 is opened to spray, and when the water in the water storage tank is insufficient, the water is firstly fed into the water storage tank to the sufficient amount, and then the washing device 2 is opened to spray. In addition, it should be noted that the water inlet to the water storage tank can be controlled manually or automatically by using a pressure valve and other components, which are not described herein again.
