When the dispensing device 10 is arranged at a low position of the enzyme preparation bin 1 (a low position away from the liquid level or at the bottom of the enzyme preparation bin 1), in addition to the extraction of the enzyme solution into the dishwasher inner container by the pump body, the gravity of the enzyme solution can also be used to flow into the dishwasher inner container under the action of gravity. Or part of the gas is retained in the above pressure relief process, and the gas pressure on the liquid level is used to accelerate the flow of the enzyme solution into the dishwasher inner container.

[0050] Further, since the volume of the enzyme solution added into the dishwasher 2 inner container needs to be known when the enzyme solution is added into the dishwasher 2 inner container, a flow meter is further arranged in the connecting pipeline of the dispensing device 10 of the embodiment of the present application, which is used to record the volume of the enzyme solution flowing into the dishwasher 2 inner container. It should be noted that in order to save costs, the connecting pipeline of the dispensing device 10 in another embodiment of the present application can not be provided with a flow meter, and the volume of the enzyme solution in the enzyme preparation device flowing into the dishwasher 2 inner container can be calculated according to the diameter of the connecting pipeline and the opening time of the valve body on the connecting pipeline.

[0051] Further, the dispensing device 10 further comprises a water inlet control system connected with the water inlet of the dishwasher 2, which is used to add water into the enzyme preparation bin 1. It should be noted that the water inlet control system is provided with a water inlet pump body, a water inlet pipeline and a switch valve on the water inlet pipeline. The water inlet system extracts water into the enzyme preparation bin 1 by the water inlet pump body.

[0052] Further, a water level detection device 3 is arranged in the enzyme preparation bin 1, which is used to detect the water level of the enzyme solution in the enzyme preparation bin 1.

[0053] Further, a heating device 8 is arranged in the enzyme preparation bin 1, which is used to heat the enzyme preparation bin 1 to maintain the internal temperature of the enzyme preparation bin 1 at a preset optimal fermentation temperature. During the fermentation process, it is appropriate that the temperature in the enzyme preparation bin is maintained between 20℃-30℃.

[0054] Further, a stirring device 9 is arranged in the enzyme preparation bin 1, which is used to stir the enzyme solution in the enzyme preparation bin 1 during the enzyme preparation process to accelerate the flow of the enzyme solution, thereby promoting the fermentation process of the enzyme.

It should be noted that the cleaning agent box 4 of the embodiment of the present application can also include only one solvent bin, and the dosage of the artificial cleaning agent added into the dishwasher inner container can be controlled by controlling the time and flow of the artificial cleaning agent added into the dishwasher 2 by the cleaning agent box 4.

[0057] Figure 2 The flow chart of the control method of the dishwasher provided by the embodiment of the present application is shown in the accompanying drawings, and the control method of the dishwasher will be described below in combination with the flow chart. Figure 2 The control method of the dishwasher of the present application will be described. The dishwasher of the present application includes a dishwasher and an enzyme preparation device for preparing enzyme, and the method includes the following steps:

[0058] S1, monitoring the working process of the dishwasher;

[0059] S2, when the dishwasher performs a washing operation requiring the use of cleaning agent, controlling the enzyme preparation device to input the enzyme solution into the dishwasher inner container for the cleaning operation of the dishwasher load.

[0060] It should be noted that the enzyme concentration in the enzyme solution has a great influence on the cleaning ability of the enzyme solution, and the effective enzyme in the enzyme solution mainly plays a role in cleaning the dishes to be cleaned. Therefore, the step of controlling the enzyme preparation device to input the enzyme solution into the dishwasher inner container of the embodiment of the present application includes the following step which is not shown in the accompanying drawings:

[0061] S21, obtaining the water level information and the enzyme concentration in the enzyme preparation device, and calculating the content of the effective enzyme in the enzyme solution according to the water level information and the enzyme concentration;

[0062] Wherein, the dishwasher can obtain the water level information or the volume of the enzyme solution in the enzyme preparation device by using the letter a, and the concentration of the enzyme solution can be obtained by using the letter w through the enzyme concentration sensor, and the content of the effective enzyme in the enzyme solution can be obtained according to the formula c=a*w*x, wherein c represents the content of the effective enzyme, and x represents a compensation coefficient and the value of x is obtained according to the test correction.

[0063] S22, when the content of the effective enzyme is greater than or equal to a preset first content threshold, controlling the enzyme preparation device to input a corresponding volume of enzyme solution into the dishwasher inner tank according to the enzyme concentration.

[0064] It should be noted that when the content of the effective enzyme is greater than the preset first content threshold, it means that the content of the effective enzyme in the enzyme solution is more than the effective enzyme required to complete the cost of the cleaning operation, so at this time the enzyme preparation device needs to be controlled to input a corresponding volume of enzyme solution into the dishwasher inner tank according to the enzyme concentration. Specifically, the volume of the enzyme solution to be input corresponding to the enzyme concentration is calculated according to a preset calculation formula, and the enzyme preparation device is controlled to input the enzyme solution into the dishwasher inner tank according to the volume of the enzyme solution to be input. Specifically, after knowing the content of the effective enzyme required to complete a cleaning operation, the volume of the enzyme solution required can be obtained according to the formula c = a * w * x, where V is the volume of the enzyme solution required, C is the content of the effective enzyme required, w is the concentration of the enzyme solution, and x represents a compensation factor.

[0065] Further, when the content of the effective enzyme is less than the preset first content threshold and greater than the preset second content threshold, the enzyme preparation device is controlled to input all the enzyme solution into the dishwasher inner tank, and the dose of artificial cleaning agent to be added is calculated according to the content of the effective enzyme, and a corresponding dose of artificial cleaning agent is added to the dishwasher inner tank. Specifically, when the content of the effective enzyme is less than the preset first content threshold and greater than the preset second content threshold, it means that the content of the effective enzyme in the enzyme solution in the enzyme preparation device is too low to complete a cleaning operation, so the present embodiment also needs to supplement a super-dose of artificial cleaning agent based on the current content of the effective enzyme to complete a cleaning operation. The calculation formula for the dose of artificial cleaning agent to be added is: V 人工 = k (C - c), where V 人工 is the dose of artificial cleaning agent to be added; C is the content of the effective enzyme required to complete a cleaning operation; c is the content of the effective enzyme in the enzyme preparation device; k is the proportion coefficient of using artificial cleaning agent to replace the effective enzyme, which is preset and can be set differently for different artificial cleaning agents. It should be noted that after performing this operation step, since the enzyme solution in the enzyme preparation device has been used up, water needs to be added to the enzyme preparation device to a preset water level, and the user is prompted to replace the enzyme preparation raw material, and whether the user is prompted to replace the enzyme preparation raw material is determined according to the fermentation duration. Specifically, when the enzyme preparation duration of the enzyme preparation device is greater than a preset duration threshold, the user is prompted to replace the enzyme preparation raw material.

[0066] Further, when the content of the effective enzyme is less than or equal to a preset second content threshold, at this time the content of the effective enzyme in the enzyme preparation device is too low, at this time the enzyme solution in the enzyme preparation device will not be used to complete the washing operation, and instead an artificial cleaning agent required to complete the corresponding washing operation is added to the dishwasher inner container.

[0067] Further, when the content of the effective enzyme is less than or equal to a preset second content threshold, the method further comprises: adding water to the enzyme preparation device to a preset water level, and prompting the user to replace the enzyme preparation raw material.

[0068] In the embodiment of the present application, in order to avoid the insufficient content of the effective enzyme caused by insufficient fermentation, before the water is added to the enzyme preparation device to the preset water level and the user is prompted to replace the enzyme preparation raw material, the method further comprises: obtaining the enzyme preparation duration of the enzyme preparation device; when the enzyme preparation duration of the enzyme preparation device is greater than a preset duration threshold, the water is added to the enzyme preparation device to the preset water level, and the user is prompted to replace the enzyme preparation raw material. If the enzyme preparation duration is greater than the preset duration threshold, it proves that sufficient fermentation duration has not produced sufficient effective enzyme, at this time it is estimated that the enzyme preparation raw material needs to be replaced and water needs to be added to make the enzyme preparation device enter a new fermentation process. When the enzyme preparation duration does not reach the preset duration threshold, it proves that the insufficient content of the effective enzyme may be caused by insufficient fermentation, and the fermentation can be waited for sufficient fermentation, and then it is determined whether sufficient effective enzyme is produced.

[0069] Further, the embodiment of the present application further comprises: judging the water level information, the content of the effective enzyme and the fermentation duration in the enzyme preparation device every fixed time, and judging whether water needs to be added and prompting the user to replace the enzyme preparation raw material according to the water level information, the content of the effective enzyme and the fermentation duration in the enzyme preparation device.

[0070] Further, in order to control the rapid fermentation of the enzyme preparation raw material in the enzyme preparation device, the embodiment of the present application further comprises: controlling the temperature in the enzyme preparation device to maintain at an optimal fermentation temperature, and performing a stirring operation on the enzyme solution in the enzyme preparation device.

Secondly, those skilled in the art should know that the embodiments described in the specification all belong to preferred embodiments, and the actions involved are not necessarily required by the embodiment of the present application.
