Embodiment 1

[0055] A water level detection method for a sink, such as figure 1 As shown, the method includes steps S101-S103:

[0056] S101. Obtain the voltage value on the water level detection electrode.

[0057] In the embodiment of the present invention, such as figure 2 As shown, the cleaning tank is mainly composed of the tank body, the tank cavity, the upper cover, the overflow port and the drainer, and the water circuit components such as the washing pump and the spray arm are not shown in the figure. The upper cover is arranged on the top of the water tank body, the drainer is arranged on the bottom surface of the water tank body, and the overflow port is arranged on the side of the water tank body. The water level detection electrode can be arranged on the side of the water tank body, which is electrically connected to the control circuit through the wire, installed on the side of the water tank body through the electrode fixing block, and isolated and sealed from the water t...

Embodiment 2

[0087] The difference between this embodiment and the first embodiment is that whether the water level detection electrode is in contact with water can be directly determined by combining the voltage value of the water level detection electrode and the voltage fluctuation value.

[0088] Optionally, the method also includes:

[0089] After the voltage value of the water level detection electrode is obtained, the voltage value is compared with a preset second voltage threshold; and the water level of the water tank is judged according to the comparison result and the magnitude of the voltage fluctuation value.

[0090] In the embodiment of the present invention, it can be seen from the above water level judgment scheme that when the water does not touch the water level detection electrode and is far away from the water level detection electrode, the voltage value on the water level detection electrode is stable with little fluctuation. When the water touches the water level det...

Embodiment 3

[0111] A water level detection device 1 of a sink, such as Figure 5 As shown, the device includes: a water level detection electrode 11 , an acquisition module 12 , a detection module 13 and a judgment module 14 .

[0112] The acquiring module 12 is configured to acquire the voltage value on the water level detecting electrode 11 .

[0113] The detection module 13 is used to detect the voltage fluctuation value of the voltage value within a preset time.

[0114] The judging module 14 is used for judging the water level of the water tank according to the magnitude of the voltage fluctuation value.

[0115] In the embodiment of the present invention, any embodiment in the above-mentioned method embodiment is applicable to the device embodiment, and details will not be described again.

[0116] Optionally, one or more water level detection electrodes are installed on the side wall of the tank.

[0117] In the embodiment of the present invention, the installation positions of ...

Abstract

Embodiments of the invention disclose a method for water level detection of a water tank. The method comprises: acquiring a voltage value on a water level detection electrode; detecting a voltage fluctuation value of the voltage value within a preset time; and determining water level of the water tank according to the voltage fluctuation value. An embodiment of the invention disclose a device forwater level detection of a water tank. Through embodiment scheme of the invention, water level of the water tank can be directly and accurately detected without being influenced by water quality.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of cooking device control, in particular to a water level detection method and device for a sink. Background technique [0002] The sink is an essential piece of equipment in the home kitchen. At present, there are more and more smart cleaning sinks on the market, which can automatically clean fruits and vegetables, dishes, etc. [0003] When cleaning, the control of the water level is very critical. Too much water will waste water resources, and too little water will lead to unclean cleaning. At present, the main method of controlling the water level of the intelligent cleaning tank is to use the flowmeter to calculate the water inflow. The flowmeter itself has certain errors. The water intake time is prolonged. In addition, the flowmeter can only indirectly judge the water level in the tank through the amount of water inflow, rather than direct measurement. When the water pressu...
