Water inlet detection method of food processor and food processor

Abstract

The invention discloses a water inlet detection method of a food processor and the food processor. The food processor comprises a water tank, a cup body, a water level detection module used for detecting whether water exists in the water tank or not and a water pump with a preset water pumping speed. The water tank and the cup body are directly communicated through a pipeline, the water level detection module is arranged on the pipeline, and the water inlet detection method of the food processor comprises the steps that a main control circuit obtains a detection result of the water level detection module, and the detection result is used for indicating whether water exists in the water tank or not; the main control circuit controls the water pump to pump water at a preset water pumping speed according to whether water exists in the water tank; wherein the corresponding preset water pumping speeds are different when water exists in the water tank and no water exists in the water tank. According to the water inlet detection method of the food processor and the food processor, residual water and residual air pressure in the pipeline between the water tank and the water pump can be emptied, so that the influence of the residual water and the steam pressure in the pipeline is avoided, and the reliability of water existence detection or water level detection is improved.

Description

technical field [0001] The application relates to the field of kitchen appliances, in particular to a method for detecting water inflow of a food processing machine and the food processing machine. Background technique [0002] In the existing detection of water intake or water level of food processors with water tanks (such as wall breaking machines that can automatically feed water for pulping or cleaning, soybean milk machines, etc.), some food processors use flow meters to calculate water intake or pressure sensor detection Water level, but the installation structure of the flow meter or pressure sensor is complicated and costly; some food processors use metal electrodes for water level / water detection, and metal electrodes are used for water level / water detection. Metal electrodes are required An isolation structure is set to ensure the reliability of its detection. Therefore, in the existing scheme, an electrode installation cavity is provided for the metal electrode, ...

Problems solved by technology

[0002] In existing food processing machines with water tanks (such as wall breakers, soybean milk machines, etc., which can automatically enter water for pulping or cleaning), some food processing machines use flow meters to calculate water intake or pressure sensor detection Water level, but the installation structure of the flow meter or pressure sensor is complicated and costly; some food processors use metal electrodes for water level / water detection, and metal electrodes are used for water level / water detection. Metal electrodes are required An isolation structure is set to ensure the reliability of its detection. Therefore, in the existing scheme, an electrode installation cavity is provided for the metal electrode, and the water in the water tank enters the electrode installation cavity. Whether there is water or not, but the design cost of this method of setting the electrode installation cavity is greatly increased, and the electrode installation cavity takes up a lot of space, resulting in a larger volume of the food processor
