Embodiment 1

[0041] The embodiment of the present invention provides a water detection method for a food processing machine, such as figure 1 As shown, the food processing machine may include: a water pump DL and a current detection device; the current detection device includes a sampling resistor R1 and a main control unit MCU; as figure 2 As shown, the method may include S101-S103:

[0042] S101. During the working period of the water pump, detect the water temperature at the water outlet of the food processing machine in real time;

[0043] S102. When the water temperature is lower than a preset water temperature threshold, sample the working current of the water pump through the sampling resistor R1;

[0044] S103. During the sampling period of the sampling resistor, acquire the sampling voltage on the sampling resistor in real time through the main control unit MCU, compare the sampling voltage with a preset voltage threshold, and compare the sampling voltage with the preset voltage...

Embodiment 2

[0063] On the basis of the first embodiment, this embodiment provides an embodiment of accurately judging whether there is water or not by combining the water level electrode detection method.

[0064] In an exemplary embodiment of the present invention, the food processor may also include: a water level detection electrode; the method may also include:

[0065] During the working period of the water pump, the water temperature at the water outlet of the food processor is detected in real time;

[0066] When the water temperature is greater than or equal to a preset water temperature threshold, the water level detection electrode is used to detect whether there is water in the pipeline of the current food processor.

[0067] In the exemplary embodiment of the present invention, because the ion product of water will increase with the increase of temperature, when a certain problem T is reached, the problem of water or no water can be effectively distinguished by means of electr...

Embodiment 3

[0074] On the basis of the first or second embodiment, this embodiment provides an embodiment that if the operating current is large, it is judged that the waterway is blocked, and an alarm and other processing can be performed.

[0075] In an exemplary embodiment of the present invention, the method may further include: comparing the sampled operating current of the water pump with a preset current threshold; when the operating current is greater than or equal to the current threshold, determining The pipeline is blocked and an alarm is issued.

[0076] In an exemplary embodiment of the present invention, if the working current is large and the voltage across the sampling resistor exceeds the set upper limit value Vpk (Vpk>V1), it means that the waterway is blocked, and abnormal alarm processing can be performed.

[0077] In an exemplary embodiment of the present invention, when the position of the water outlet is blocked, if only the detection scheme of the water level elect...

Abstract

The embodiment of the present invention discloses a water detection method for a food processing machine. The food processing machine includes: a water pump and a current detection device; the current detection device includes a sampling resistor and a main control unit; the method includes: during the operation of the water pump, real-time Detect the water temperature at the water outlet of the food processor; when the water temperature is lower than the preset water temperature threshold, sample the working current of the water pump through the sampling resistor; during the sampling period of the sampling resistor, The main control unit acquires the sampling voltage on the sampling resistor in real time, compares the sampling voltage with a preset voltage threshold, and judges whether the current food processor pipeline is have water. Through the solution of this embodiment, it is possible to accurately detect whether there is water in the pipeline of the food processor without being affected by the water quality.
