Problems solved by technology

[0004] However, if no sensor is installed to detect the feeding port or the feeding motor, not only the opening and closing state of the feeding port cannot be detected, but also the failure of the feeding motor cannot be found in time. On the one hand, the materials that have not been cleaned by the washing box It directly enters the cooking part through the unclosable feeding port, which affects the user's food hygiene. On the other hand, during the cooking process, the hot steam in the cooking cavity flows back to the storage part through the non-closable feeding port, which may cause storage of materials Bacterial growth or deterioration, which seriously affects the reliability of the automatic cooking function of the cooking appliance and the user experience

Embodiment 1

[0055] figure 1 A schematic flowchart of the operation control method of the feeding motor according to Embodiment 1 of the present invention is shown.

[0056] like figure 1 As shown, the operation control method of the blanking motor according to Embodiment 1 of the present invention includes: step S102, controlling the blanking motor to close the blanking port according to the first steering signal, and recording the initial moment when the first steering signal is generated; step S104, within the first preset time period counted from the initial moment, detect whether the rotation speed signal of the feeding motor is switched to a stall signal; step S106, determine whether the feeding port is closed according to the detection result of the rotation speed signal.

[0057] In this technical solution, within the first preset time period counted from the initial moment, it is detected whether the speed signal of the feeding motor is switched to a stall signal, and it is deter...

Embodiment 2

[0073] figure 2 A schematic diagram of the circuit interface of the feeding motor according to the second embodiment of the present invention is shown.

[0074] like figure 2 As shown, the circuit interface of the blanking motor according to Embodiment 2 of the present invention includes:

[0075] (1) VCC, GND: respectively power supply and ground, which are output by the control system to provide power to the feeding motor. Among them, the control system is logic control devices such as MCU, DSP, CPU and embedded equipment.

[0076] (2) FG: It is the first feedback interface of the feeding motor, which is used to output the load signal to the control system to detect the speed of the feeding motor. The number of FG pulses per unit time is different for different speeds of the feeding motor. The number of pulses is obtained from experiments. When the feeding motor is running, the FG pin outputs pulses continuously.

[0077] (3) RD: It is the second feedback interface of t...

Embodiment 3

[0082] image 3 A schematic flowchart of the operation control method of the feeding motor according to the third embodiment of the present invention is shown.

[0083] like image 3 As shown, the operation control method of the unloading motor according to the third embodiment of the present invention includes: step S302, driving the unloading motor to close the unloading port of the washing box, and starting the timer at the same time, setting the timeout time as T; S304, read the rotation speed signal output by the feeding motor, and record it as rd1; step S306, judge whether rd1 is switched to the stall signal rd2 within the first preset time length; step S308, switch from rd1 to the stall signal rd2 if it is not detected, Then control the feeding motor to open the feeding port, and control the feeding motor to close the feeding port again; Step S310, it is not detected within the second preset time length that rd1 is switched to a stall signal rd2; Step S312, it is deter...

Abstract

The invention provides an operation control method and device of a discharging motor, a cooking utensil and a storage medium. he operation control method of the discharging motor comprises the steps:controlling the discharging motor to close a discharging port according to a first steering signal, and recording an initial moment when the first steering signal is generated; detecting whether the rotating speed signal of the discharging motor is switched into a locked-rotor signal or not within a first preset duration from the initial moment; and determining whether the discharge port is in a closed state or not according to a detection result of the rotating speed signal. According to the technical scheme, on the premise that no extra sensor needs to be arranged, whether the motor closes the discharging opening of the material washing box or not is accurately detected, and when the motor cannot close the discharging opening, prompt information is generated in time to prompt a user, andthe cooking process is stopped to reduce the fault rate of the cooking utensil.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a method for controlling the operation of a feeding motor, a device for controlling the operation of a feeding motor, a cooking utensil, and a computer-readable storage medium. Background technique [0002] In order to simplify the user's operation steps and shorten the waiting time for cooking, an automatic cooking appliance has been developed, which can automatically perform the processes of feeding rice, feeding water, washing rice, draining and washing rice water, putting rice into the pot, heating and cooking, and keeping warm. [0003] In the related art, a washing box is provided in the cooking utensil, and the washing box can be connected to the material storage part, and the materials stored in the storage part are transported to the washing box for cleaning through the feeding pipeline, and the washing box is passed through the lower part of the washing box. The ...
