Therefore, this application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in this application.

[0049] It should be noted that since the method of the embodiment of this application is executed in a refrigeration device, the processing objects of each refrigeration device exist in the form of data or information. For example, time, which is essentially time information. It can be understood that in subsequent embodiments, if dimensions, quantities, positions, etc. are mentioned, they are all corresponding data existences for the refrigeration device to process, and specific details are not elaborated here.

[0050] Please refer to Figure 1 , Figure 1 FIG. is a schematic flowchart of an embodiment of the device control method provided by the embodiment of this application. The device control method may include the following steps S201 to S203, specifically as follows:

[0051] Step S201, obtain the ambient temperature information corresponding to the refrigeration device.

[0052] In the embodiment of this application, the refrigeration device is any device with a refrigeration function. The refrigeration device may be one or more of a refrigerator, a freezer, a refrigerated truck, an ice maker, a refrigerated box, etc. The ambient temperature information corresponding to the refrigeration device is used to characterize the hot and cold degree of the environment around the refrigeration device. The ambient temperature information corresponding to the refrigeration device can be obtained through a temperature sensor configured in the refrigeration device itself, or can also be obtained from other devices through means such as a network or Bluetooth. This embodiment does not make a limitation here.

[0053] Step S202, if the temperature value corresponding to the ambient temperature information is greater than the first temperature threshold, obtain the working mode corresponding to the refrigeration device.

[0054] In the embodiment of this application, the first temperature threshold is a temperature threshold preset for measuring whether the temperature value corresponding to the ambient temperature information is too high. The first temperature threshold can be set according to actual needs. Optionally, the first temperature threshold can be set to 30°C to 50°C. For example, the first temperature threshold can be set to 30°C, the first temperature threshold can also be set to 40°C, and the first temperature threshold can also be set to 50°C.

[0055] Further, the working mode refers to different operating methods or operational states adopted by the refrigeration equipment during operation to meet different task requirements, adapt to different working environments, or achieve specific functional goals. Optionally, the working modes corresponding to the refrigeration equipment include a defrosting mode, and / or a refrigeration mode, and / or a quick-freezing mode, and / or an energy-saving mode, and / or an intelligent mode. Among them, the refrigeration mode is the most basic working mode of the refrigeration equipment. In the refrigeration mode, the compressor operates and drives the refrigerant to evaporate and absorb heat in the evaporator, reducing the internal temperature of the refrigeration equipment to achieve the purpose of refrigerating or freezing food; the defrosting mode is set to periodically remove the frost layer on the surface of the evaporator. When the defrosting mode is started, the refrigeration system of the refrigeration equipment stops working, and at the same time, a heating device is started or other defrosting methods are adopted to heat the frost layer on the surface of the evaporator to melt it into water; the quick-freezing mode is a working mode in which the refrigeration system operates at the maximum refrigeration power to quickly reduce the temperature of the freezer compartment to a very low temperature in a short time.

[0056] Step S203: If the working mode is the defrosting mode, control the stepper motor to drive the diversion vane to rotate so that the freezing air damper of the refrigeration equipment is in a closed state.

[0057] In the embodiment of the present application, the equipment control method is applied to a refrigeration equipment, which includes a stepper motor and a diversion vane. The stepper motor provides power for the opening and closing of the freezing air damper of the refrigeration equipment. The stepper motor can receive a control signal and accurately control the rotation angle and speed of the diversion vane according to the set temperature and operating mode, so as to accurately adjust the opening degree of the freezing air damper.

[0058] In this embodiment, if the temperature value corresponding to the ambient temperature information is greater than the first temperature threshold and the working mode corresponding to the refrigeration equipment is the defrosting mode, then control the stepper motor to drive the diversion vane to rotate, so that the freezing air damper of the refrigeration equipment can be in a closed state, avoiding hot air from flowing back to the freezing compartment through the freezing air damper, and preventing the temperature of the freezing compartment of the refrigeration equipment from rising too high during defrosting at high ambient temperature.

[0059] In some embodiments, the refrigeration equipment further includes a position sensor, which is used to detect the rotation angle and position of the diversion vane and feedback this information to the controller of the refrigeration equipment, enabling the controller to understand the state of the freezing air damper in real time and achieve accurate control and monitoring of the opening degree of the freezing air damper. The position sensor can be one or more of a Hall position sensor, a capacitive position sensor, an inductive position sensor, an ultrasonic position sensor, an optoelectronic position sensor, etc. Optionally, the position sensor can be a Hall position sensor, which can accurately detect the change of the magnetic field and then convert it into accurate position information, and the detection accuracy can reach the millimeter or even micron level.

[0060] Further, the step of controlling the stepper motor to drive the guide vane to rotate in step S203 so that the freezing air damper of the refrigeration device is in a closed state specifically includes: obtaining the current position information of the guide vane through a position sensor; determining the first rotation angle of the guide vane based on the current position information and the target position information; determining the first target speed of the stepper motor based on the first rotation angle and the first time; controlling the stepper motor to drive the guide vane to rotate based on the first target speed so that the freezing air damper of the refrigeration device is in a closed state.

[0061] In the embodiment of the present application, the target position information is the position information corresponding to the target position to which the guide vane needs to rotate. At the target position, the guide vanes are in contact with each other and the freezing air damper is in a closed state. The first rotation angle is the difference between the angle corresponding to the current position information and the angle corresponding to the target position information. For example, if the angle corresponding to the current position information is 90° and the angle corresponding to the target position information is 0°, then the first rotation angle is 90°.

[0062] In some embodiments, the step of determining the first target speed of the stepper motor based on the first rotation angle and the first time specifically includes: multiplying the transmission ratio of the stepper motor and the first rotation angle to obtain a third rotation angle; dividing the third rotation angle by the first time to obtain a fourth rotation angle; dividing the fourth rotation angle by the first angle to obtain the first target speed. For example, the first time is 1.5 s, the first rotation angle is 90°, the first angle is 360°, and the transmission ratio is 20, then the third rotation angle = 20 * 90° = 1800°, the fourth rotation angle = 1800° / 1.5 = 1200°.

[0063] In some embodiments, the refrigeration device further includes a freezing evaporator. Refer to Figure 2 As shown, after the step S203 of controlling the stepper motor to drive the guide vane to rotate so that the freezing air damper of the refrigeration device is in a closed state, steps S301 to S302 are included, which are specifically as follows:

[0064] Step S301, obtaining the first temperature information corresponding to the freezing evaporator.

[0065] In the embodiment of the present application, the first temperature information is used to characterize the cold and hot degree of the freezing evaporator. The first temperature information can be obtained through a temperature sensor configured in the refrigeration device itself, or can be obtained from other devices through networks, Bluetooth and other means. This embodiment does not make a limitation here.

[0066] Step S302: If the temperature value corresponding to the first temperature information is less than or equal to the second temperature threshold, control the stepping motor to drive the deflector vane to rotate, so as to adjust the freezing air damper from the closed state to the first opening state.

[0067] In the embodiment of the present application, the second temperature threshold is a pre-set temperature threshold for measuring the temperature of the freezing evaporator, and the second temperature threshold can be set according to actual needs. Optionally, the second temperature threshold can be set to -20°C to 0°C. For example, the second temperature threshold can be set to -20°C, -15°C, -10°C, -5°C, 0°C, etc. If the temperature value corresponding to the first temperature information is less than or equal to the second temperature threshold, it indicates that the refrigeration equipment has ended the defrosting mode, and the temperature of the freezing evaporator has dropped to the second temperature threshold, that is, there is no problem of excessive return temperature in the freezing compartment caused by defrosting at high ambient temperature. Then, control the stepping motor to drive the deflector vane to rotate, so as to adjust the freezing air damper from the closed state to the first opening state.

[0068] Further, the first opening state can be set according to actual needs, and the first opening state can be a fully open state, a half-open state, a 1 / 3 open state, etc. For example, if the temperature value corresponding to the first temperature information is less than or equal to the second temperature threshold, control the stepping motor to drive the deflector vane to rotate, so as to adjust the freezing air damper from the closed state to the fully open state.

[0069] In some embodiments, the step of controlling the stepping motor to drive the deflector vane to rotate, so as to adjust the freezing air damper from the closed state to the first opening state in step S302 specifically includes: obtaining the current position information of the deflector vane through a position sensor; determining the second target position information of the deflector vane based on the current position information and the second rotation angle; controlling the stepping motor to drive the deflector vane to rotate to the position corresponding to the second target position information; if the residence time of the deflector vane at the position corresponding to the second target position information reaches the time threshold, determine the second target position information as the current position information, and continue to execute the step of determining the second target position information of the deflector vane based on the current position information and the second rotation angle until the deflector vane rotates to the position corresponding to the third target position information.

[0070] In the embodiments of the present application, the second rotation angle is the angle that the guide vane needs to rotate, which can be set according to actual requirements. Optionally, the second rotation angle can be set to 5° to 20°. For example, the second rotation angle can be set to 5°, 10°, 15°, 20°, etc. Optionally, the step of determining the second target position information of the guide vane based on the current position information and the second rotation angle specifically includes: adding the angle corresponding to the current position information and the second rotation angle to obtain the second target position information of the guide vane. For example, if the angle corresponding to the current position information is 0° and the second rotation angle is 10°, then the second target position information is 10°.

[0071] Further, the time threshold is a preset threshold, which can be set according to actual requirements. For example, the time threshold can be set to 5 seconds, 10 seconds, 15 seconds, 20 seconds, etc. The third target position information is preset position information. The third position information can be the position information corresponding to the guide vane being opened to the maximum, or the position information corresponding to the guide vane being opened to a certain extent. This embodiment does not make a limitation. In this embodiment, if the residence time of the guide vane at the position corresponding to the second target position information reaches the time threshold, the second target position information is determined as the current position information, and the step of determining the second target position information of the guide vane based on the current position information and the second rotation angle is continued until the guide vane rotates to the position corresponding to the third target position information, which can realize the step-by-step opening of the guide vane, thereby avoiding the problem of temperature oscillation in the freezing compartment caused by the freezing air damper being opened to the maximum at one time. For example, after the guide vane maintains at the position of 10° for 10 s, the guide vane is controlled to open to 20°. After the guide vane maintains at the position of 20° for 10 s, the guide vane is controlled to open to 30°, and so on, until the guide vane is opened to 90°.

[0072] In some embodiments, as shown in Figure 3 After controlling the stepping motor to drive the guide vane to rotate in step S203 above so that the freezing air damper of the refrigeration equipment is in a closed state, it includes steps S401 to S403, which are specifically as follows:

[0073] Step S401: Collect the first pressure value through the first pressure sensor and collect the second pressure value through the second pressure sensor.

[0074] In the embodiment of the present application, the refrigeration device further includes a freezing evaporator, a freezing compartment, a first pressure sensor, and a second pressure sensor. The first pressure sensor is arranged at the outlet of the freezing evaporator, and the second pressure sensor is arranged at the top of the freezing compartment. The first pressure value is collected by the first pressure sensor and the second pressure value is collected by the second pressure sensor. Based on the first pressure value and the second pressure value, the air pressure difference inside and outside the refrigeration device can be determined, avoiding an excessive air pressure difference inside and outside the refrigeration device.

[0075] Step S402: Calculate and process the first pressure value and the second pressure value to obtain a first pressure difference.

[0076] In some embodiments, the step of calculating and processing the first pressure value and the second pressure value to obtain a first pressure difference specifically includes: subtracting the second pressure value from the first pressure value to obtain a first pressure difference. For example, if the first pressure value is 0 Pa and the second pressure value is 25 Pa, then the first pressure difference is 25 Pa.

[0077] Step S403: If the first pressure difference is greater than a first pressure threshold, control the stepper motor to drive the guide vane to rotate so that the freezing air door is adjusted from a closed state to a second opening state.

[0078] In the embodiment of the present application, the first pressure threshold is a pre-set pressure threshold for measuring whether the air pressure difference inside and outside the refrigeration device is too large. The first pressure threshold can be set according to actual needs. In some embodiments, the first pressure threshold can be set to 20 Pa - 30 Pa. For example, the first pressure threshold can be set to 20 Pa, 25 Pa, 30 Pa, etc. If the first pressure difference is greater than the first pressure threshold, it indicates that the air pressure difference inside and outside the refrigeration device is too large. Then, control the stepper motor to drive the guide vane to rotate so that the freezing air door is adjusted from a closed state to a first opening state, which can avoid an excessive air pressure difference inside and outside.

[0079] Further, the opening value corresponding to the second opening state is less than or equal to a first opening threshold. The first opening threshold can be set according to actual needs. In some embodiments, the first opening threshold can be set to 3% - 10%. For example, the first opening threshold can be set to 3%, 5%, 10%, etc. In addition, the first opening threshold can also be determined according to the first pressure difference. For example, when the first pressure difference is 25 Pa, the first opening threshold is 5%; when the first pressure difference is 26 Pa, the first opening threshold is 8%; when the first pressure difference is 27 Pa, the first opening threshold is 10%. In this embodiment, by controlling the opening value corresponding to the first opening state to be less than the first opening threshold, while adjusting the internal and external pressure difference, the problem that the temperature in the freezing compartment rises too high during defrosting at a high ambient temperature due to an overly large opening of the freezing air door can be avoided.

[0080] In some embodiments, the refrigeration device further includes a ventilation hole, which can be a honeycomb ventilation hole, a circular ventilation hole, or a square ventilation hole. This embodiment does not make any limitations. Optionally, the ventilation hole is a honeycomb ventilation hole, which is composed of numerous closely arranged small holes. Each small hole can ventilate independently, providing a relatively large ventilation area per unit area, enabling air to pass through smoothly and achieving efficient ventilation and air exchange.

[0081] Furthermore, the diameter of the ventilation hole can be set according to actual requirements. For example, the diameter of the ventilation hole can be 2 mm, 1 mm, or 3 mm. This embodiment does not make any limitations. Optionally, the ventilation hole is a honeycomb ventilation hole with a diameter of 2 mm. This ventilation hole can not only enable air to pass through smoothly, but also has a relatively large contact area between the air flow and the hole wall, making the friction and damping effects of the air flow more obvious, which helps to suppress the high-frequency noise components in the air flow and makes the ventilation process quieter.

[0082] In some embodiments, after calculating and processing the first pressure value and the second pressure value to obtain the first pressure difference, it includes: if the first pressure difference is greater than the second pressure threshold, the ventilation hole is opened.

[0083] In the embodiments of the present application, the second pressure threshold is a pre-set pressure threshold for measuring whether the air pressure difference between the inside and outside of the refrigeration device is too large. The second pressure threshold can be set according to actual requirements. Optionally, the second pressure threshold can be set to 25 Pa - 35 Pa. For example, the second pressure threshold can be set to 25 Pa, 30 Pa, 35 Pa, etc. Furthermore, the second pressure threshold is greater than the first pressure threshold. For example, the second pressure threshold can be 30 Pa, and the first pressure threshold can be 25 Pa. If the first pressure difference is greater than the second pressure threshold, the ventilation hole is opened, and ventilation is carried out through the ventilation hole, which can reduce the air pressure difference between the inside and outside of the refrigeration device.

[0084] In some embodiments, if the first pressure difference is greater than the second pressure threshold, in addition to opening the ventilation hole, the stepping motor can also be controlled to drive the guide vane to rotate, so that the freezing air damper is adjusted from the closed state to the second opening state, which can quickly reduce the internal and external pressure difference of the refrigeration device and prevent the internal and external pressure difference from being too large.

[0085] In some embodiments, after controlling the stepper motor to drive the diversion vane to rotate in step S403 above so that the refrigeration air damper is adjusted from the closed state to the second opening state, the following steps are included: collecting a third pressure value through a first pressure sensor and collecting a fourth pressure value through a second pressure sensor; calculating and processing the third pressure value and the fourth pressure value to obtain a second pressure difference; if the second pressure difference is less than or equal to a third pressure threshold, controlling the stepper motor to drive the diversion vane to rotate so that the refrigeration air damper is adjusted from the second opening state to the closed state.

[0086] In the embodiments of the present application, the third pressure threshold is a pre-set pressure threshold for measuring whether the second pressure difference meets the requirements. The third pressure threshold can be set according to actual needs. In some embodiments, the third pressure threshold can be set to 15 Pa to 25 Pa. For example, the third pressure threshold can be set to 15 Pa, 20 Pa, 25 Pa, etc. Optionally, the third pressure threshold is less than the first pressure threshold, and the first pressure threshold is less than the second pressure threshold. For example, the third pressure threshold can be 20 Pa, the first pressure threshold can be 25 Pa, and the second pressure threshold can be 30 Pa. In the embodiments of the present application, if the second pressure difference is less than or equal to the third pressure threshold, it indicates that the air pressure difference inside and outside the refrigeration equipment has been reduced to the requirements, and then the stepper motor is controlled to drive the diversion vane to rotate so that the refrigeration air damper is adjusted from the second opening state to the closed state, which can avoid the problem of excessive temperature rise in the freezing compartment during defrosting at high ambient temperature when the refrigeration air damper is opened.

[0087] To better implement the equipment control method in the embodiments of the present application, based on the equipment control method, an equipment control device is further provided in the embodiments of the present application, as Figure 4 shown. The equipment control device 600 includes:

[0088] A first acquisition module 610, configured to acquire ambient temperature information corresponding to the refrigeration equipment;

[0089] A second acquisition module 620, configured to acquire the working mode corresponding to the refrigeration equipment if the temperature value corresponding to the ambient temperature information is greater than a first temperature threshold;

[0090] An equipment control module 630, configured to control the stepper motor to drive the diversion vane to rotate so that the refrigeration air damper of the refrigeration equipment is in a closed state if the working mode is a defrosting mode.
