Problems solved by technology

[0003] A food processing machine in the prior art can adjust the total amount of food preparation to facilitate the user's control experience. It uses a water tank for water supply, so it is necessary to detect the water level of the water tank in order to better control the progress of the food processing machine. Water quantity, in the prior art, basically adopt devices such as water level electrode, infrared pair tube or reed switch to realize the detection of set point signal for water level detection in the prior art, although the detection of water level can be realized, there are following defects: 1. The point is a fixed point, it is impossible to continuously detect the water level, the water volume cannot be precisely controlled, and the user experience is poor
2. The accuracy, reliability, and response speed of the detection are affected by factors such as the external environment, structure, fittings, and device performance, and there is a risk of abnormal equipment failure

Embodiment 1

[0022] The present invention relates to a control method of a food processing machine. The food processing machine includes a water tank and a processing cavity for food processing, wherein the food processing machine is provided with an ultrasonic sensor for detecting the water level in the water tank. The food processing is also provided with a temperature detection device for detecting the water temperature in the water tank, and the food processing machine adjusts the water level value detected by the ultrasonic sensor according to the water temperature.

[0023] like figure 1 , 2, the water tank 1 and the processing chamber 2 are set on the base 3 of the food processor, and the ultrasonic sensor 4 is set on the base 3 . The water tank 1 is detachably installed on the machine base 3 , and a silica gel 5 is provided in front of the ultrasonic sensor 4 and the water tank 1 , and the upper surface of the silica gel 5 is higher than the surface of the machine base 3 . A water...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that: the water level detected by the ultrasonic sensor in the water tank is h, the temperature detected by the temperature sensor is T, and the food processing machine is provided with fixed temperature compensation coefficients A and B and 0°C The following corresponds to system C, H=(A*T*T+B*T+C)*h. In this implementation, A=-0.0000257, B=0.0031, and C=0.93. Among them, A*T*T+B*T+C is the temperature correction coefficient of the distance value read by the ultrasonic sensor at the measurement temperature T. This value is based on the coefficient corresponding to 0°C and passed the one-to-two value under the corresponding coefficient of the actual temperature detection point. The value of ABC is a fixed coefficient value specific to the ultrasonic sensor, and the function of temperature correction is realized through the algorithm equation fitting calculation.

[0035] By using the ultrasonic sensor to detect...

Abstract

The invention discloses a control method of a food processing machine. The food processing machine includes a water tank, and a processing chamber for food processing. An ultrasonic sensor for detecting the water level of the water tank is disposed on the food processing machine. A temperature detection device for detecting the water temperature in the water tank is further disposed on the food processing machine. The food processing machine adjusts a water level value detected by the ultrasonic sensor according to the water temperature. Continuous water level detection can be achieved by detecting the water level of the water tank using the ultrasonic sensor, so as to accurately control the water entering the processing chamber, and in this way, the food processing machine is allowed to intelligently control the material entry. Meanwhile, the temperature sensor is disposed at a water inlet / outlet between the water tank and a base, the water temperature of the water tank can be monitored in real time, so that the water level value monitored by the ultrasonic sensor can be corrected to enable more accurate water level monitoring, and thus, the food processing machine is allowed to process food more intelligently.

Description

technical field [0001] The invention relates to the control field of household kitchen appliances, in particular to a control method of a food processing machine. Background technique [0002] With the continuous development of control technology, it has brought great changes to human life, and more and more intelligent household appliances have entered people's lives and improved people's living standards. The reason why these intelligent household appliances can be intelligent is because of their intelligent control and intelligent operation. [0003] A food processing machine in the prior art can adjust the total amount of food preparation to facilitate the user's control experience. It uses a water tank for water supply, so it is necessary to detect the water level of the water tank in order to better control the progress of the food processing machine. Water quantity, in the prior art, basically adopt devices such as water level electrode, infrared pair tube or reed ...
