Embodiment 1

[0034] Embodiment 1 of the present invention provides a kind of turbidity detection method for dishwasher, such as figure 1 As shown, it specifically includes the following steps:

[0035] S1, tap water flows into the cavity of the dishwasher through the water inlet component 1;

[0036] The water inlet assembly 1 includes a water inlet pipe 11 and a water inlet solenoid valve 12. The water inlet solenoid valve 12 is arranged on the water inlet pipe 11. The water inlet pipe 11 communicates with the cavity of the dishwasher. When in use, the water inlet solenoid valve 12 To control the connection between the water inlet pipe 11 and the cavity of the dishwasher;

[0037] S2, the turbidity detection component 3 detects the initial capacitance c of the tap water in the dishwasher cavity 0 Value; wherein, the turbidity detection assembly 3 communicates with the dishwasher cavity;

[0038] Such as figure 2 As shown, the turbidity detection assembly 3 includes a ground electrode...

Embodiment 2

[0056] Embodiment 2 of the present invention provides a turbidity detection system for dishwashers, which uses the turbidity detection method in Embodiment 1, such as Figure 5 Shown:

[0057] It includes a water inlet component 1, a drain component 2, a turbidity detection component 3 and a dishwasher body 4, wherein:

[0058] The turbidity detection assembly 3 is located at the bottom of the cavity of the dishwasher body 4 and the two are connected, the water inlet assembly 1 guides tap water to the turbidity detection assembly 3, and the drain assembly 2 is connected to the turbidity detection assembly 3 Commonly used to drain water;

[0059] In this way, with the above structure, tap water first flows into the dishwasher body 4 through the water inlet assembly 1, and the turbidity detection assembly 3 detects the capacitance c of the current tap water. 0 , and then turn on the cleaning function of the dishwasher; the turbidity detection component 3 detects the current ca...

Abstract

The invention discloses a turbidity detection method for a dishwasher. The turbidity detection method specifically comprises the following steps that S1, tap water flows into a dishwasher cavity through a water inlet assembly; S2, the turbidity detection assembly detects the initial capacitance c0 of tap water in the dishwasher cavity, wherein the turbidity detection assembly is communicated withthe dishwasher cavity; S3, the cleaning function of the dishwasher is started; S4, the turbidity detection assembly detects the current capacitance value ct in the dishwasher cavity in real time; S5,the ratio of the current capacitance value ct to the initial capacitance value c0 is calculated, namely the current turbidity value. The invention further discloses a turbidity detection system for the dishwasher. The current turbidity is calculated according to the capacitance value of the solution in the dishwasher cavity at the initial moment and the capacitance value at the current moment. Thestrict requirements of a turbidity sensor on the detection environment are avoided. The method is low in cost, simple and easy to implement, low in requirement for detection conditions and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and in particular relates to a turbidity detection method and detection system for dishwashers. Background technique [0002] The turbidity sensor is a low-cost sensor used in home appliances. It is mainly used to measure the degree of water pollution in washing machines, dishwashers and other products. The washing time and number of rinses. [0003] However, the turbidity sensor has very strict standards for light source intensity and temperature. Changes in light source intensity and temperature will affect the measurement accuracy of the sensor, especially when it is applied to a dishwasher, the measurement error will affect the quality of the dishes. Cleanliness affects human health. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the present invention provides a turbidity detection method for dishwashers. The current turbidity is calculated ...
