[0003] Currently, refrigerator thermostats on the market are mainly of two types: mechanical thermostats and electronic thermostats. Mechanical thermostats work by the expansion or contraction of gas inside a temperature-sensing bulb, which mechanically triggers the switch.

[0047] This application provides a method for controlling the temperature of a refrigerator. For an example, please refer to [link to example]. Figure 1 , Figure 1 A flowchart illustrating a refrigerator temperature control method provided in this application embodiment. The refrigerator includes a rotary temperature control switch, which includes a knob unit. The temperature control method includes the following steps S101-S103:
[0048] Step S101: Obtain the current position of the knob unit;
[0049] A refrigerator's rotary temperature control switch is a temperature control device that adjusts the refrigerator's temperature by rotating a knob. The knob unit is designed for manual rotation so that the control module receives the user-set refrigerator temperature. The position of the knob unit corresponds to the refrigerator's set temperature; for example, rotating the knob unit clockwise by a preset angle, such as 10°, lowers the refrigerator's set temperature by a preset value, such as 0.5°C.
[0050] Step S102: Based on the continuous mapping relationship between the knob position and the set temperature, determine the target temperature currently set by the corresponding knob temperature control switch according to the current position.
[0051] The set temperature can represent the refrigerator's start-up temperature or stop-down temperature. When the detected temperature rises to the start-up temperature, the refrigerator begins cooling the storage compartment; when the detected temperature drops to the stop-down temperature, the refrigerator stops cooling the storage compartment. By setting the start-up and stop-down temperatures, the fluctuation range of the refrigerator's internal temperature can be limited, ensuring the internal temperature remains within the range that meets cooling requirements and provides good preservation. For example, the set temperature represents the refrigerator's stop-down temperature. Each clockwise rotation of the knob unit by a preset angle, such as 10°, lowers the stop-down temperature by a preset temperature value, such as 0.5°C. The refrigerator's start-up temperature can be a fixed value or positively correlated with the stop-down temperature; no specific limitation is made here.
[0052] In some embodiments, the set temperature can also be a temperature range, including a start-up temperature and a stop-down temperature. For example, for every clockwise rotation of the knob unit by a preset angle, such as 10°, the stop-down temperature of the refrigerator decreases by a preset temperature value, such as 0.5°C, and the start-up temperature of the refrigerator also decreases by a preset temperature value, such as 0.5°C.
[0053] In refrigerators, temperature is detected using temperature sensors. The location of the temperature sensor varies depending on the refrigerator's cooling method and air vent configuration. For example, in a direct-cooling refrigerator, the temperature sensor might be located in the evaporator chamber, while in a frost-free refrigerator, it could be located in the refrigerator or freezer compartment. In practical applications, designers need to determine the set temperature range based on the sensor's location to ensure the temperature within the storage compartment meets the actual storage requirements.
[0054] It should be noted that the continuous mapping relationship between the knob position and the set temperature is f: θ → T; where the set θ represents the set of several knob positions of the knob unit, T represents the set of several set temperatures of the refrigerator, and the mapping f is continuous on the set θ; that is, for θ0 ∈ θ, t0 ∈ f(θ0), and for any neighborhood U(t0) of t0, there can always be a neighborhood U(θ0) of θ0 such that
[0055] Understandably, regardless of the knob's position, the corresponding set temperature, or target temperature, can be determined based on the continuous mapping between the knob position and the set temperature. In practical applications, users can adjust the refrigerator's set temperature by rotating the knob at any angle within the specified range. For example, a user can rotate the knob 30° to adjust the set temperature by 3°C, 10° to adjust by 1°C, 5° to adjust by 0.5°C, or even just 1° to adjust by 0.1°C. Thus, by establishing a continuous mapping between the knob position and the set temperature, minute adjustments to the refrigerator's set temperature can be achieved, improving the accuracy of temperature adjustment and ensuring the refrigerator's temperature meets the user's actual needs.
[0056] Step S103: Control the temperature of the refrigerator based on the target temperature.
[0057] Temperature control in a refrigerator based on a target temperature aims to maintain the temperature of the storage compartment within a range that meets the user's needs. In practical applications, this can be achieved by adjusting the operating status of the refrigerator's compressor, fan, and damper.
[0058] The refrigerator temperature control method provided in this application embodiment sets a continuous mapping relationship between the knob position and the set temperature. Based on the continuous mapping relationship and the position of the knob unit, the currently set target temperature is determined, which can realize stepless adjustment of the knob temperature control switch. By adjusting the set temperature of the refrigerator by a small amount, the adjustment accuracy of the set temperature is improved, ensuring that the refrigerator temperature can meet the actual use needs of the user.
[0059] Optionally, determining the target temperature currently set by the knob temperature control switch based on the continuous mapping relationship between the knob position and the set temperature includes: obtaining a calculation model including the continuous mapping relationship, wherein the calculation model is T = f(θ, t); where T represents the target temperature, θ represents the knob position, and t represents the set temperature; and inputting the current position into the calculation model to obtain the target temperature currently set by the knob temperature control switch.
[0060] In some embodiments, before determining the target temperature currently set by the corresponding knob temperature control switch based on the continuous mapping relationship between the knob position and the set temperature, the temperature control method further includes:
[0061] Get the current ambient temperature;
[0062] Determine the continuous mapping relationship corresponding to the ambient temperature from the pre-stored set of mapping relationships.
[0063] The ambient temperature is obtained through an environmental sensor, such as a temperature sensor.
[0064] It should be noted that the mapping relationship set includes continuous mapping relationships between various knob positions and set temperatures, as well as one-to-one correspondences between multiple ambient temperature ranges. Determining the continuous mapping relationship corresponding to the ambient temperature from the pre-stored mapping relationship set may include: determining the target ambient temperature range into which the current ambient temperature falls; and, based on the mapping relationship set, determining the continuous mapping relationship corresponding to the target ambient temperature threshold from the continuous mapping relationships between various knob positions and set temperatures.
[0065] Understandably, ambient temperature affects the refrigerator's heat dissipation efficiency and start-stop cycle. To ensure the refrigerator achieves its best storage performance, the continuous mapping between the knob position and the set temperature is adaptively adjusted according to the current ambient temperature, and the refrigerator's temperature is controlled based on the target temperature. This can reduce the performance impact of the refrigerator under extreme ambient temperatures.
[0066] In some embodiments, temperature control of the refrigerator based on a target temperature includes:
[0067] The target temperature is rounded to obtain the adjusted target temperature.
[0068] The refrigerator's temperature is controlled based on the adjusted target temperature.
[0069] The target temperature is rounded, meaning the obtained target temperature is rounded to the nearest hundredth decimal place. For example, the target temperature can be rounded to one decimal place to obtain a rounded target temperature. For instance, if the target temperature is -22.05°C, after rounding, the rounded target temperature will be 22.0°C. This improves the feasibility of controlling the refrigerator's temperature based on the target temperature.
[0070] Optionally, temperature control of the refrigerator based on the adjusted target temperature includes:
[0071] Get the current temperature of the refrigerator;
[0072] The refrigerator is temperature controlled based on the current temperature and the adjusted target temperature.
[0073] The current temperature of the refrigerator can be obtained through a temperature sensor, which can be installed in the evaporator, refrigerator compartment, or freezer compartment. The specific sensor can be selected by the designer based on the actual compartment cooling method and damper setting of the refrigerator.
[0074] In practical applications, the refrigerator's cooling system is compared to the corrected target temperature to determine whether to turn the cooling on or off, thus maintaining the refrigerator's temperature within a range that meets the user's needs. For example, the target temperature is the refrigerator's stop temperature set by the current rotary temperature control switch. A temperature sensor is installed on the refrigerator's evaporator plate and monitors the current temperature in real time. When the current temperature rises to the preset start-up temperature, the refrigerator begins cooling; when the current temperature reaches the corrected target temperature, the refrigerator stops cooling.
[0075] For a specific example of how to achieve temperature control in a refrigerator, the refrigerator includes a compressor, a fan, and a damper. Temperature control of the refrigerator based on the current temperature and the adjusted target temperature includes:
[0076] Control the operating status of the compressor, fan, and damper according to the current temperature and the adjusted target temperature;
[0077] The operating parameters of the compressor, fan, and damper are controlled according to the adjusted target temperature.
[0078] It should be noted that when the compressor is turned on, the refrigerator's refrigeration system begins to work, and the evaporator cools the surrounding air through heat exchange. The damper is adapted to open the air vent to connect the evaporator chamber and the storage compartment, or to close the air vent to isolate the evaporator chamber from the storage compartment. The fan is adapted to operate to drive the cold air from the evaporator chamber into the refrigerator's storage compartment, thereby achieving cooling of the storage compartment.
[0079] For example, the adjusted target temperature is the refrigerator's stop point temperature set by the current rotary temperature control switch. When the current temperature is detected to rise to the preset start point temperature, the compressor, fan, and damper are controlled to start working to cool the storage compartment; when the current temperature reaches the adjusted target temperature, the compressor, fan, and damper are controlled to stop working to stop cooling the storage compartment.
[0080] The compressor's set operating parameters include the set operating frequency, the fan's set operating parameters include the set speed, and the damper's set operating parameters include the set opening degree. The refrigerator controls the operating parameters of the compressor, fan, and damper according to the adjusted target temperature to achieve the desired cooling efficiency of the storage compartment. This improves temperature control efficiency, reduces temperature fluctuations in the storage compartment, and ultimately achieves optimal refrigerator performance.
[0081] For example, the adjusted target temperature is the refrigerator's stop temperature set by the current rotary temperature control switch. The refrigerator's start temperature is a fixed value. Therefore, the compressor's set operating frequency, the fan's set speed, and the damper's set opening degree are negatively correlated. That is, the greater the difference between the refrigerator's stop and start temperatures, the greater the relative increase in the compressor's set operating frequency, fan speed, and damper opening degree, thus increasing the cooling rate of the storage compartment and allowing it to quickly reach the temperature required for user storage. Conversely, the smaller the difference between the stop and start temperatures, the smaller the relative decrease in these parameters, thus slowing down the cooling rate of the storage compartment and preventing excessive internal temperature fluctuations.
[0082] In some embodiments, obtaining the current position of the knob unit includes:
[0083] In response to the operation action on the knob unit, the rotation angle of the knob unit is obtained;
[0084] The current position of the knob unit is determined based on the rotation angle.
[0085] The operation actions and rotation angle of the knob unit are obtained through a rotation detection device, such as a rotary encoder.
[0086] The refrigerator temperature control method provided in this application embodiment sets a continuous mapping relationship between the knob position and the set temperature. Based on the continuous mapping relationship and the position of the knob unit, the currently set target temperature is determined, which can realize stepless adjustment of the knob temperature control switch. By adjusting the set temperature of the refrigerator by a small amount, the adjustment accuracy of the set temperature is improved, ensuring that the refrigerator temperature can meet the actual use needs of the user.
[0087] This application also provides a temperature control device for a refrigerator; for example, please refer to [link to example]. Figure 2 , Figure 2 This is a schematic diagram of the structure of a refrigerator temperature control device provided in an embodiment of this application. The refrigerator includes a rotary temperature control switch, which includes a knob unit. The refrigerator temperature control device 200 includes an acquisition module 210, a processing module 220, and a control module 230.
[0088] The acquisition module 210 is used to acquire the current position of the knob unit; the processing module 220 is used to determine the target temperature currently set by the corresponding knob temperature control switch based on the continuous mapping relationship between the knob position and the set temperature; and the control module 230 is used to control the temperature of the refrigerator based on the target temperature.
[0089] The refrigerator temperature control device 200 provided in this application embodiment sets a continuous mapping relationship between the knob position and the set temperature. Based on the continuous mapping relationship and the position of the knob unit, the target temperature is determined, which can realize stepless adjustment of the knob temperature control switch. By adjusting the set temperature of the refrigerator by a small amount, the adjustment accuracy of the set temperature is improved, ensuring that the temperature of the refrigerator can meet the actual use needs of the user.
[0090] This application also provides a refrigerator, for example, please refer to [link to example]. Figures 3-4 , Figure 3 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. Figure 4 This is another structural schematic diagram of a refrigerator provided in an embodiment of this application. The refrigerator 300 can be as follows: Figure 3 The French-style refrigerator shown can also be a single-door refrigerator, a side-by-side refrigerator, a cross-door refrigerator, or other types of refrigerators. Refrigerator 300 includes a rotary temperature control switch 310 and a controller 320.
[0091] The rotary temperature control switch 310 includes a rotary unit 311 and a detection module 312. The detection module 312 is connected to the rotary unit 311 and is used to detect the current position of the rotary unit 311. The controller 320 is connected to the detection module 312 and is used to: obtain the current position of the rotary unit; determine the target temperature currently set by the corresponding rotary temperature control switch based on the continuous mapping relationship between the knob position and the set temperature; and control the temperature of the refrigerator based on the target temperature.
[0092] For example, the detection module 312 includes a rotary encoder, and a knob unit 311 is mounted on the rotary encoder. Specifically, the knob unit 311 is nested on the rotating part of the rotary encoder. When the knob unit 311 is rotated, it is linked to the rotating part of the rotary encoder to drive the rotating part to rotate. The rotary encoder can be a magnetic encoder or an optical encoder. The knob can be a circular knob, a polygonal knob, etc. When the rotating part of the rotary encoder rotates, it outputs a signal through the output pin. By manipulating the knob unit 311, the rotary encoder can be triggered to generate a corresponding output signal. The controller 320 is electrically connected to the output pin of the rotary encoder and is adapted to receive the output signal generated by the rotary encoder and determine the current position of the knob unit based on the output signal.
[0093] In one embodiment, the output signal generated by the rotary encoder is a pulse signal. Specifically, the rotary encoder can rotate freely, and rotating a specific angle can output a certain number of pulse waveforms. Further, the controller 320 is used to identify the rotation state of the knob unit 311 based on the level characteristics and measurement values of the detected pulse signals, and to determine the current position of the knob unit based on the rotation state of the knob unit 311. Here, the level characteristics refer to the high or low voltage of the detected pulse waveform; for example, when the controller 320 detects a voltage of "1", it determines that the pulse signal is at a high level; when the controller 320 detects a voltage of "0", it determines that the pulse signal is at a low level. The measurement value refers to the statistical number of specific pulse waves per unit time. The rotation state of the knob unit 311 includes the rotation direction and rotation angle.
[0094] In some embodiments, the knob unit is marked with multiple primary positions, and several secondary positions are marked between each pair of adjacent primary positions. For example, the knob unit is marked with 8 primary positions, and 10 secondary positions are marked between each pair of adjacent primary positions. This allows the user to observe the adjustment amount when operating the knob unit, improving the accuracy of the adjustment.
[0095] The controller 320 can be a microprocessor, capable of fetching instructions, executing instructions, and exchanging information with external memory and logic components. Optionally, the controller 320 can also be a microcontroller (MCU), also known as a single-chip microcomputer (SCU) or microcontroller.
[0096] Refrigerator 300 also includes controlled devices such as compressors, fans, and dampers. In practical applications, controller 320 generates control commands for the controlled devices based on the target temperature, for example, to achieve temperature control of the refrigerator.
[0097] The refrigerator 300 provided in this application embodiment sets a continuous mapping relationship between the knob position and the set temperature. Based on the continuous mapping relationship and the position of the knob unit 311, the target temperature is determined, which can realize stepless adjustment of the knob temperature control switch 310. By adjusting the set temperature of the refrigerator 300 by a small amplitude, the adjustment accuracy of the set temperature is improved, ensuring that the temperature of the refrigerator 300 can meet the actual use needs of the user.
