Embodiment 1

[0037] Such as Figures 1 to 4 As shown, the present invention provides a food processing machine with accurate weighing, which includes a machine base 1, a weighing unit and a main control board. The machine base 1 includes a casing 11 and a bottom cover 12 arranged below the casing. The weighing control board electrically connected to the main control board and the pressure sensor 2 electrically connected to the weighing control board, the pressure sensor 2 is arranged on the bottom cover 12, refer to figure 1 The frame structure shown can be used for noodle machines and juice extractors, refer to figure 2 The base structure shown can be used for food processors, soybean milk makers, and of course, the structure of some ovens, frying machines, air fryers, etc. is also different. Anyway, the structure of the base is based on the specific application. Depending on the situation, the base here generally refers to the base of all types of food processing machines. Since there ...

Embodiment 2

[0069] The difference between this embodiment and Embodiment 1 is that the number of pressure sensors is different.

[0070] In this example, if Figure 5 As shown, the pressure sensor includes a calibration sensor 21 and a load-bearing sensor 22, that is, there are two pressure sensors, and the load-bearing sensor 22 is located at the center of gravity of the bottom cover 12, that is, the center of gravity of the food processor, and is weighed by a single point support. There is no problem of inaccurate weighing caused by multi-point support and no force on the same plane. Only one calibration sensor and one load-bearing sensor are used to detect the weight, which not only ensures the accuracy of the detection, but also reduces the number of pressure sensors and food. The manufacturing cost of the processing machine.

[0071] The structures and beneficial effects of other parts not described are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0073] The difference between this embodiment and Embodiment 1 is that the number of pressure sensors is different.

[0074] In this example, if Figure 6 As shown, the pressure sensor is provided with three and includes a calibration sensor 21 and two load-bearing sensors 22. It is weighed by two-point support, and the two-point support is easy to be stressed on the same plane to ensure the accuracy of weighing, and the two load-bearing The sensors 22 are distributed diagonally, and the calibration sensor 21 is distributed on any one of the other two corners of the bottom cover 12, which can better ensure that the two load-bearing sensors are simultaneously stressed on the same plane, and better ensure the accuracy of weighing .

[0075] The structures and beneficial effects of other parts not described are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides an accurate-weighing food processing machine and a weighing method. The machine comprises an engine base, a weighing unit and a main control board. The engine base comprises a shell and a bottom cover arranged below the shell. The weighing unit includes a weighing control board electrically connected to the main control board and a pressure sensor electrically connected to the weighing control board. The pressure sensor is arranged on the bottom cover, and the pressure sensor includes a calibration sensor and at least one load-bearing sensor. The calibration sensor is suspended and is set in an unstressed state. The calibration sensor compensates and calibrates a difference value generated by the load-bearing sensor influenced by a working environment so that weight of food is calculated, which can well avoid problems that the pressure sensor is affected by the working environment (a temperature, a humidity or other factors) and weighing is not accurate. Weighing accuracy of the food processing machine is greatly improved to ensure reliability and stability of working of the food processing machine, and convenience of user usage is also improved so that user experience and satisfaction are increased.

Description

technical field [0001] The invention relates to the field of food processing machines, in particular to a food processing machine with accurate weighing and a weighing method. Background technique [0002] With the improvement of people's living standards, people's demand for small kitchen appliances is increasing day by day. Food processors are more and more popular among people, and they also bring some convenience to people's lives. [0003] In some existing food processing machines, in order to improve the degree of automation, a weighing unit is provided at the bottom of the machine base, which is convenient for users to operate and use, and greatly solves the problem of operation convenience and user experience. [0004] The existing weighing unit generally includes a pressure sensor, but the pressure sensor is easily disturbed by the external environment, especially by temperature and humidity, which will lead to inaccurate weighing data, thereby affecting the process...
