[0033] In the refrigerator 1 provided by the present application, it includes a box body 10, a refrigeration system 13, a heating system 14, a first temperature sensing device 15 and a second temperature sensing device 16. Among them, a refrigerating chamber 11 and a freezing chamber 12 are arranged inside the box body 10. The refrigeration system 13 is used to cool the refrigerating chamber 11 and the freezing chamber 12, so as to realize the refrigeration function of the refrigerating chamber 11 and the freezing function of the freezing chamber 12. The heating system 14 is used to heat up the refrigerating chamber 11. Under the refrigeration effect of the refrigeration system 13, relying on the heating system 14 to heat up the refrigerating chamber 11 so that the refrigerating chamber 11 is maintained at a specific temperature.

That is, in the refrigerator 1 provided by the present application, the temperatures of the refrigerating chamber 11 and the freezing chamber 12 are controllable separately, so that the performance of the refrigerator 1 is improved.

[0034] In a feasible implementation manner, the box body 10 includes a refrigerating box inner liner 101 and a freezing box inner liner 102. A refrigerating chamber 11 is formed inside the refrigerating box inner liner 101, and a freezing chamber 12 is formed inside the freezing box inner liner 102. Among them, the inner side of the refrigerating box inner liner 101 defines the refrigerating chamber 11, and the refrigerating box inner liner 101 can be in direct contact with the objects inside the refrigerating chamber 11. The inner side of the freezing box inner liner 102 defines the freezing chamber 12, and the inner liner of the freezing chamber 12 can be in direct contact with the objects inside the freezing chamber 12.

[0035] In a feasible implementation manner, the refrigeration system 13 includes a compressor, a condenser, a freezing evaporator 131 and a refrigerating evaporator 132 connected in series through a refrigerant pipeline in sequence. The refrigerating evaporator 132 is fixed on the side of the refrigerating box inner liner 101 facing away from the refrigerating chamber 11, and the freezing evaporator 131 is fixed on the side of the freezing box inner liner 102 facing away from the freezing chamber 12.

[0036] In the above implementation manner, the compressor, the condenser, the freezing evaporator 131 and the refrigerating evaporator 132 are used to realize the refrigeration of the refrigerator 1. Among them, the refrigerating evaporator 132 is used to realize the refrigeration of the refrigerating chamber 11, and the freezing evaporator 131 is used to realize the refrigeration of the freezing chamber 12.

[0037] In the above embodiments, the refrigerating evaporator 132 is fixed to the side of the inner liner 101 of the refrigerator compartment facing away from the refrigerating chamber 11. Specifically, it can be fixed to the surface of the inner liner 101 of the refrigerator compartment facing away from the refrigerating chamber 11, or it can also be fixed to other structures located on the side of the inner liner 101 of the refrigerator compartment facing away from the refrigerating chamber 11. For example, a heat-insulating layer or the like can be provided on the side of the inner liner 101 of the refrigerator compartment facing away from the refrigerating chamber 11, and the refrigerating evaporator 132 can be arranged inside the heat-insulating layer or between the inner liner 101 of the refrigerator compartment and the heat-insulating layer. The freezing evaporator 131 is fixed to the side of the inner liner 102 of the freezer compartment facing away from the freezing chamber 12. Specifically, it can be fixed to the surface of the inner liner 102 of the freezer compartment facing away from the freezing chamber 12, or it can also be fixed to other structures located on the side of the inner liner 102 of the freezer compartment facing away from the freezing chamber 12. For example, a heat-insulating layer or the like can be provided on the side of the inner liner 102 of the freezer compartment facing away from the freezing chamber 12, and the freezing evaporator 131 can be arranged inside the heat-insulating layer or between the inner liner 102 of the freezer compartment and the heat-insulating layer.

[0038] Specifically, the refrigeration system 13 may further include a dryer filter. One end of the dryer filter is connected to the condenser, and the other end is connected to the freezing evaporator 131. The dryer filter serves to filter impurities.

[0039] Specifically, as Figure 1 and Figure 3 shown, the refrigeration system 13 further includes a throttling device. The throttling device may include a capillary tube 133. One end of the throttling device is connected to the condenser, and the other end is connected to the freezing evaporator 131.

[0040] Specifically, the refrigerator 1 may further include a door body, and the door body is installed on the cabinet 10 to open or close the refrigerating chamber 11 and the freezing chamber 12.

[0041] In the related art refrigerator 1, the temperature of the refrigerating chamber 11 is controllable, while the temperature of the freezing chamber 12 is uncontrollable, so that the size of the freezing evaporator 131 is relatively large. Specifically, in the related art, the switch of the compressor is controlled by the temperature of the refrigerating chamber 11. When the temperature of the refrigerating chamber 11 is relatively low, it is necessary to turn off the compressor so that the refrigerating evaporator 132 does not work, thereby increasing the temperature of the refrigerating chamber 11. At this time, in order to ensure the low temperature of the freezing chamber 12, the size of the freezing evaporator 131 needs to be set relatively large. In the refrigerator 1 provided in the present application, the temperatures of the refrigerating chamber 11 and the freezing chamber 12 are respectively controllable. When the temperature of the refrigerating chamber 11 is relatively low, the temperature can be compensated by the heating system 14 without turning off the refrigeration system 13. Therefore, the size of the freezing evaporator 131 can be set relatively small, thereby reducing the manufacturing cost. At the same time, since the temperatures of the refrigerating chamber 11 and the freezing chamber 12 are respectively controllable, when the temperature of the refrigerating chamber 11 is too low, the temperature can be compensated by the heating system 14. Thus, when the refrigerating temperature of the refrigeration system 13 is relatively low, the situation where the temperature of the refrigerating chamber 11 is lower than zero degree Celsius can be avoided.

[0042] In a feasible implementation, the heating system 14 is fixed to the surface of the inner liner 101 of the refrigerator on the side facing away from the refrigerating chamber 11. Alternatively, the heating system 14 is located on the side of the inner liner 101 of the refrigerator facing away from the refrigerating chamber 11 and is fixed to the refrigerating evaporator 132.

[0043] In the above implementation, the heating system 14 may include a heating wire. Heating with a heating wire has a simple structure and low cost. The heating system 14 may further include a power supply module for supplying power to the heating wire.

[0044] Specifically, the heating system 14 can compensate for the temperature of the refrigerating chamber 11, control the temperature of the refrigerating chamber 11 within a set temperature range, and prevent the temperature of the refrigerating chamber 11 from dropping below zero degrees Celsius.

[0045] Specifically, the heating system 14 can be fixed to the surface of the inner liner 101 of the refrigerator on the side facing away from the refrigerating chamber 11. Among them, the heating wire can be directly fixed to the surface of the inner liner 101 of the refrigerator on the side facing away from the refrigerating chamber 11. The surface of the inner liner 101 facing away from the refrigerator is flat, and it is easier to fix to the heating wire, which helps to reduce the manufacturing difficulty. Alternatively, it is located on the side of the inner liner 101 of the refrigerator facing away from the refrigerating chamber 11 and is fixed to the refrigerating evaporator 132. The heating system 14 is in direct contact with the refrigerating evaporator 132, so that the temperature of the heating system 14 can directly act on the refrigerating evaporator 132, and the heating effect is more direct and significant.

[0046] In the above implementation, in order to make the temperature uniformity of the refrigerating chamber 11 better, the heating system 14 can be arranged close to the refrigerating evaporator 132. Specifically, it includes being fixed to the surface of the inner liner 101 of the refrigerator on the side facing away from the refrigerating chamber 11 and in contact with the refrigerating evaporator 132, or being directly fixed to the refrigerating evaporator 132.

[0047] Specifically, the fixing method of the heating wire to the inner liner 101 of the refrigerator or the refrigerating evaporator 132 can be adhesive fixing. The fixing method is simple and easy to operate.

[0048] In a feasible implementation, the heating system 14 includes a heating circuit. The first temperature sensing device 15 is connected in series in the heating circuit. The first temperature sensing device 15 is configured to conduct the heating circuit when the temperature is lower than the first temperature threshold range, and deform to disconnect the heating circuit when the temperature exceeds the first temperature threshold range.

[0049] In the above embodiments, the heating system 14 includes a heating circuit, and the heating circuit includes a heating wire. The first temperature sensing device 15 is connected in series to the heating circuit, that is, the first temperature sensing device 15 is arranged in series with the heating wire. The first temperature sensing device 15 may include a mechanical temperature control switch. When the first temperature sensing device 15 senses that the temperature in the refrigerating chamber 11 is lower than the first temperature threshold range, the mechanical temperature control switch automatically closes, so that the heating circuit is turned on, and the heating system 14 operates to supplement the temperature of the refrigerating chamber 11. When the first temperature sensing device 15 senses that the temperature in the refrigerating chamber 11 exceeds the first temperature threshold range, the mechanical temperature control switch automatically opens, so that the heating circuit is disconnected, and the heating system 14 stops operating to stop supplementing the temperature of the refrigerating chamber 11, thereby limiting the temperature of the refrigerating chamber 11 within a preset temperature range to achieve temperature control of the refrigerating chamber 11.

[0050] Specifically, when the first temperature sensing device 15 is a mechanical temperature control switch, the sensing information of the first temperature sensing device 15 includes the information of sensing the ambient temperature and performing switching or closing operations, and the heating system 14 is configured to be turned on or off under the action of the above sensing information.

[0051] Specifically, the first temperature sensing device 15 and the heating wire are connected by a wired connection.

[0052] Specifically, the mechanical temperature control switch is a series of automatic control components that generate physical deformation inside the mechanical temperature control switch according to the temperature change of the working environment, thereby generating certain special effects and generating conduction or disconnection actions. The temperature control switch includes switches that are turned on and off through temperature changes, such as liquid expansion type temperature controllers and pressure type temperature controllers. The liquid expansion type temperature controller is when the temperature of the controlled object changes, the substance (usually liquid) in the temperature sensing part of the temperature controller generates corresponding thermal expansion and contraction physical phenomena (volume change), and the bellows connected to the temperature sensing part expands or contracts, and drives the switch to turn on and off by the lever principle. The pressure type temperature controller converts the change of the controlled temperature into the change of space pressure or volume through a sealed temperature package filled with temperature sensing working medium and a capillary 133. When the temperature setting value is reached, the contact is automatically closed through an elastic element and a quick-acting mechanism.

[0053] In a feasible embodiment, the heating system 14 includes a heating circuit, the refrigerator 1 further includes a first control component, the first temperature sensing device 15 includes a first temperature sensor, the first temperature sensor is signal-connected to the first control component, and the first control component controls the heating circuit to be turned on or off according to the temperature information detected by the first temperature sensor.

[0054] In the above embodiments, the refrigerator 1 includes a first control component, which may be located within the control system of the refrigerator 1. Alternatively, the refrigerator 1 includes a first control component, and the first control component and the first temperature sensor are integrated to form an electronic temperature control switch. When the first control component is located within the control system of the refrigerator 1, the heating circuit may include an electronic switch, and the first control component is connected to the electronic switch and can control the opening or closing of the electronic switch. When the first control component and the first temperature sensor are integrated to form an electronic temperature control switch, the electronic temperature control switch can automatically open or close according to the temperature sensed by the first temperature sensor.

[0055] In the above embodiments, the first control component is signal-connected to the first temperature sensor, and the signal connection may specifically include a wired connection and a wireless connection. The wireless connection methods include, but are not limited to, Bluetooth connection and wireless network (wifi) connection.

[0056] In the above embodiments, the temperature information detected by the first temperature sensor may be a first temperature, and the first temperature is a specific temperature value. The first control component can control the heating circuit to turn on or off according to the first temperature.

[0057] In a feasible embodiment, the refrigeration system 13 includes a refrigeration circuit, and the second temperature sensing device 16 is connected in series to the refrigeration circuit. The second temperature sensing device 16 is configured to disconnect the refrigeration circuit when the temperature is lower than the second temperature threshold range, and deform to close the refrigeration circuit when the temperature exceeds the second temperature threshold range.

[0058] Specifically, the above compressor, condenser, freezer evaporator 131, and refrigerating evaporator 132 may be connected in series in the refrigeration circuit synchronously.

[0059] In the above embodiments, the second temperature sensing device 16 is connected in series to the refrigeration circuit, that is, the second temperature sensing device 16 is connected in series with the compressor, condenser, freezer evaporator 131, and refrigerating evaporator 132. The second temperature sensing device 16 may include a mechanical temperature control switch. When the second temperature sensing device 16 senses that the temperature in the freezer 12 is lower than the second temperature threshold range, the mechanical temperature control switch automatically turns on, so that the refrigeration system 13 stops working to increase the temperature of the freezer 12. When the second temperature sensing device 16 senses that the temperature in the freezer 12 exceeds the second temperature threshold range, the mechanical temperature control switch automatically closes, so that the refrigeration system 13 works to lower the temperature of the freezer 12. Through the above process, the temperature of the freezer 12 can be limited within a preset temperature range to achieve temperature control of the freezer 12.

[0060] Specifically, when the second temperature sensing device 16 is a mechanical temperature control switch, the sensing information of the second temperature sensing device 16 includes the information of sensing the ambient temperature and performing the switching or closing operation, and the refrigeration system 13 is configured to be turned on or off under the action of the above sensing information.

[0061] In a feasible implementation manner, the refrigeration system 13 includes a refrigeration circuit, the refrigerator 1 further includes a second control component, the second temperature sensing device 16 includes a second temperature sensor, the second temperature sensor is signal-connected to the second control component, and the second control component controls the refrigeration circuit to be turned on or off according to the temperature information detected by the second temperature sensor.

[0062] In the above implementation manner, the refrigerator 1 includes a second control component, and the second control component may be located in the control system of the refrigerator 1. Alternatively, the refrigerator 1 includes a second control component, and the second control component and the second temperature sensor are integrated to form an electronic temperature control switch. When the second control component is located in the control system of the refrigerator 1, the refrigeration circuit may include an electronic switch, and the second control component is connected to the electronic switch in the refrigeration circuit and can control the electronic switch to be turned on or off. When the second control component and the second temperature sensor are integrated to form an electronic temperature control switch, the electronic temperature control switch can be automatically turned on or off according to the temperature sensed by the second temperature sensor.

[0063] In the above implementation manner, the second control component is signal-connected to the second temperature sensor, and the signal connection may specifically include a wired connection and a wireless connection. The wireless connection methods include but are not limited to Bluetooth connection and wireless network (wifi) connection.

[0064] In the above implementation manner, the temperature information detected by the second temperature sensor may be the second temperature, the second temperature is a specific temperature value, and the second control component can control the refrigeration circuit to be turned on or off according to the second temperature.

[0065] Specifically, when the first control component and the second control component are located in the control system of the refrigerator 1, they may be integrated into one body.

[0066] In a feasible implementation manner, the first temperature sensing device 15 is fixed on the surface of the inner liner 101 of the refrigerating chamber facing away from the refrigerating compartment 11, or the first temperature sensing device 15 is located on the side of the inner liner 101 of the refrigerating chamber facing the refrigerating compartment 11, or the first temperature sensing device 15 is located on the side of the inner liner 101 of the refrigerating chamber facing away from the refrigerating compartment 11 and is fixed to the refrigerating evaporator 132.

[0067] In the above embodiments, the first temperature sensing device 15 can be fixed to the refrigerating evaporator 132 to detect the temperature of the refrigerating evaporator 132, and the temperature of the refrigerating evaporator 132 is detected as the basis for measuring the temperature of the refrigerating chamber 11. Alternatively, the first temperature sensing device 15 can be fixed to the side of the inner liner 101 of the refrigerator compartment facing away from the refrigerating chamber 11, that is, outside the refrigerating chamber 11. Specifically, it can be fixed to the surface of the inner liner 101 of the refrigerator compartment on the side facing away from the door body, and is used to detect the temperature of the inner liner 101 of the refrigerator compartment. This fixing method is simple and has a better detection effect. Alternatively, the first temperature sensing device 15 can also be fixed inside the inner liner 101 of the refrigerator compartment to directly detect the temperature inside the refrigerating chamber 11, and the detection result is more accurate.

[0068] Specifically, when the first temperature sensing device 15 is connected to the heating system 14 (or the first control component) in a wired connection manner and the first temperature sensing device 15 is located on the side of the inner liner 101 of the refrigerator compartment facing the refrigerating chamber 11, the first temperature sensing device 15 and the heating system 14 (or the first control component) can be connected by a connecting wire passing through the inner liner 101 of the refrigerator compartment.

[0069] In a feasible embodiment, the second temperature sensing device 16 is fixed to the surface of the inner liner 102 of the freezer compartment facing away from the freezer 12. Alternatively, the second temperature sensing device 16 is located on the side of the inner liner 102 of the freezer compartment facing the freezer 12. Alternatively, the second temperature sensing device 16 is located on the side of the inner liner 102 of the freezer compartment facing away from the freezer 12 and is fixed to the refrigerating evaporator 131.

[0070] In the above embodiments, the second temperature sensing device 16 can be fixed to the refrigerating evaporator 131 to detect the temperature of the refrigerating evaporator 131, and the temperature of the refrigerating evaporator 131 is detected as the basis for measuring the temperature of the freezer 12. Alternatively, the second temperature sensing device 16 can be fixed to the side of the inner liner 102 of the freezer compartment facing away from the freezer 12, that is, outside the freezer 12. Specifically, it can be fixed to the surface of the inner liner 102 of the freezer compartment on the side facing away from the door body, and is used to detect the temperature of the inner liner 102 of the freezer compartment. This fixing method is simple and has a better detection effect.

[0071] In the above two fixing methods, both the second temperature sensing device 16 and the refrigeration system 13 (or the second control component) are located outside the inner liner 102 of the freezer compartment, which is convenient for the second temperature sensing device 16 to be connected to the refrigeration system 13 (or the second control component) in a wired manner.

[0072] Alternatively, the second temperature sensing device 16 can be fixed to the side of the inner liner 102 of the freezer compartment facing the freezer 12 to directly detect the temperature inside the freezer 12, and the detection result is more accurate. At this time, when the second temperature sensing device 16 and the refrigeration system 13 or the second control component can be connected by a connecting wire passing through the inner liner 102 of the freezer compartment.

[0073] The present application also provides a control method for a refrigerator 1, which includes a refrigerating chamber 11, a freezing chamber 12, a heating system 14 for heating the refrigerating chamber 11, and a refrigerating system 13 for cooling the refrigerating chamber 11 and the freezing chamber 12. As Figure 4 shown, the control method includes the following steps:

[0074] S200, obtaining the current temperature of the refrigerating chamber 11 as the first temperature, and controlling the heating system 14 to operate according to the first temperature.

[0075] Specifically, the current temperature of the refrigerating chamber 11 can be obtained through a first temperature sensing device 15 in the refrigerator 1. At this time, the first temperature sensing device 15 includes a first temperature sensor. After obtaining the first temperature of the refrigerating chamber 11 through the first temperature sensor, the heating system 14 can be controlled to operate through a first control component.

[0076] S400, obtaining the current temperature of the freezing chamber 12 as the second temperature, and controlling the refrigerating system 13 to operate according to the second temperature.

[0077] Specifically, the current temperature of the freezing chamber 12 can be obtained through a second temperature sensing device 16 in the refrigerator 1. At this time, the second temperature sensing device 16 includes a second temperature sensor. After obtaining the second temperature of the freezing chamber 12 through the second temperature sensor, the refrigerating system 13 can be controlled to operate through a second control component.

[0078] In the control method for the refrigerator 1 provided by the present application, by obtaining the temperature of the refrigerating chamber 11 to control the operation of the heating system 14, the temperature of the refrigerating chamber 11 is controlled, and by obtaining the temperature of the freezing chamber 12 to control the operation of the refrigerating system 13, the temperature of the freezing chamber 12 is controlled. Under this control method, the temperatures of the refrigerating chamber 11 and the freezing chamber 12 are respectively controllable. The low temperature of the refrigerating chamber 11 is provided by the refrigerating system 13. When the temperature of the refrigerating chamber 11 is too low, the heating system 14 can be used to heat the refrigerating chamber 11 to raise its temperature. When the temperature of the refrigerating chamber 11 is relatively high, the heating system 14 can be turned off, so that the refrigerating system 13 can continue to cool the refrigerating chamber 11. The low temperature of the freezing chamber 12 is provided by the refrigerating system 13. When the temperature of the refrigerating chamber 11 is too low, the refrigerating system 13 can be turned off to raise the temperature of the freezing chamber 12. When the temperature of the freezing chamber 12 is relatively high, the refrigerating system 13 can be started, so that the refrigerating system 13 can continue to cool the freezing chamber 12. The control method of this refrigerator 1 enables the temperatures of the refrigerating chamber 11 and the freezing chamber 12 of the refrigerator 1 to be respectively controllable, improving the performance of the refrigerator 1.

[0079] In a feasible implementation manner, the step of controlling the heating system 14 to operate according to the first temperature includes:

[0080] Control the operation of the heating system 14 according to that the first temperature is less than or equal to the first shutdown temperature threshold Trt;

[0081] Control the heating system 14 to stop working according to that the first temperature is greater than or equal to the first startup temperature threshold Trk.

[0082] In the above embodiment, the first shutdown temperature threshold Trt of the refrigerating chamber 11 is the lowest temperature preset for the refrigerating chamber 11, the first startup temperature threshold Trk is the highest temperature preset for the refrigerating chamber 11, the first shutdown temperature threshold Trt is less than the first startup temperature threshold Trk, and the ideal temperature range of the refrigerating chamber 11 is the range from the first shutdown temperature threshold Trt to the first startup temperature threshold Trk. When the first temperature is less than or equal to the first shutdown temperature threshold Trt, the temperature of the refrigerating chamber 11 is too low, and the temperature needs to be increased so that the temperature of the refrigerating chamber 11 is within the ideal temperature range of the refrigerating chamber 11. At this time, the first control component controls the heating system 14 to heat up to raise the temperature of the refrigerating chamber 11 to within the ideal temperature range of the refrigerating chamber 11. During the temperature increase process, the temperature of the refrigerating chamber 11 is continuously detected. When the first temperature is greater than or equal to the first startup temperature threshold Trk, the temperature of the refrigerating chamber 11 has exceeded the ideal temperature range of the refrigerating chamber 11, and the first control component controls the heating system 14 to stop working to cool down the refrigerating chamber 11, and so on.

[0083] Specifically, when the first temperature is greater than the first shutdown temperature threshold Trt and less than the first startup temperature threshold Trk, no operation is required for the heating system 14.

[0084] Specifically, the values of the first shutdown temperature threshold Trt and the first startup temperature threshold Trk are temperature values preset manually, and the values of the first shutdown temperature threshold Trt and the first startup temperature threshold Trk of different refrigerators 1 may be different.

[0085] Specifically, the first control component in the refrigerator 1 can be used to compare the first temperature with the first shutdown temperature threshold Trt and the first startup temperature threshold Trk of the refrigerating chamber 11.

[0086] In a feasible embodiment, the steps of controlling the operation of the refrigeration system 13 according to the second temperature include:

[0087] Control the refrigeration system 13 to stop working according to that the second temperature is less than or equal to the second shutdown temperature threshold Tft;

[0088] Control the refrigeration system 13 to work according to that the second temperature is greater than or equal to the second startup temperature threshold Tfk.

[0089] In the above embodiment, the second shutdown temperature threshold Tft of the freezer compartment 12 is the lowest temperature preset for the freezer compartment 12, the second startup temperature threshold Tfk is the highest temperature preset for the freezer compartment 12, the second shutdown temperature threshold Tft is less than the second startup temperature threshold Tfk, and the ideal temperature range of the freezer compartment 12 is the range from the second shutdown temperature threshold Tft to the second startup temperature threshold Tfk. When the second temperature is less than or equal to the second shutdown temperature threshold Tft, the temperature of the freezer compartment 12 is too low and the temperature needs to be raised so that the temperature of the freezer compartment 12 is within the ideal temperature range of the freezer compartment 12. At this time, the refrigeration system 13 is controlled by the second control component to stop refrigerating so as to raise the temperature of the freezer compartment 12 to within the ideal temperature range of the freezer compartment 12. During the temperature increase process, the temperature of the freezer compartment 12 is continuously detected. When the second temperature is greater than or equal to the second startup temperature threshold Tfk, the temperature of the freezer compartment 12 has exceeded the ideal temperature range of the freezer compartment 12, and the refrigeration system 13 needs to be controlled by the second control component to start refrigerating so as to cool the freezer compartment 12 under the action of the refrigeration system 13, and so on.

[0090] Specifically, when the second temperature is greater than the second shutdown temperature threshold Tft and less than the second startup temperature threshold Tfk, no operation is required for the refrigeration system 13.

[0091] Specifically, the values of the second shutdown temperature threshold Tft and the second startup temperature threshold Tfk are temperature values preset manually, and the values of the second shutdown temperature threshold Tft and the second startup temperature threshold Tfk of different refrigerators 1 may be different.

[0092] Specifically, the second temperature can be compared with the second shutdown temperature threshold Tft and the second startup temperature threshold Tfk of the refrigerating compartment 11 through the second control component in the refrigerator 1.

[0093] In a feasible embodiment, the control method of the refrigerator 1 further includes:

[0094] Obtain the ambient temperature at which the refrigerator 1 is currently located and obtain the current operating state of the refrigerator 1;

[0095] According to the ambient temperature and the current operating state of the refrigerator 1, determine the first shutdown temperature threshold Trt, the first startup temperature threshold Trk, the second shutdown temperature threshold Tft, and the second startup temperature threshold Tfk corresponding to the current operating state. In the above embodiments, the temperature of the refrigerating chamber 11 and the freezing chamber 12 can be more precisely controlled by setting the parameters of the refrigerator 1, so that the refrigerator 1 is more intelligent. Specifically, the refrigerator 1 includes multiple ambient temperature ranges and multiple operating modes, and each ambient temperature range can correspond to multiple operating modes. A mapping relationship is established between each operating mode and each ambient temperature range and can be directly called. Each operating mode and each ambient temperature range jointly define an ideal refrigerating temperature range and an ideal freezing temperature range. The ambient temperature range in which the refrigerator 1 is located can be determined after detecting the current ambient temperature of the refrigerator 1. The operating mode in which the refrigerator 1 is located can be preset, and the operating mode of the refrigerator 1 can be manually selected during the subsequent use of the refrigerator 1.

[0096] Specifically, as shown in Table 1 below, the refrigerator 11 can include eight ambient temperature ranges, namely the first range, the second range, the third range, the fourth range, the fifth range, the sixth range, the seventh range, and the eighth range. Among them, the temperature in the first range is T1, where T1 ≤ 2°C; the temperature in the second range is T2, where 2°C < T2 ≤ 7°C; the temperature in the third range is T3, where 7°C < T3 ≤ 13°C; the temperature in the fourth range is T4, where 13°C < T4 ≤ 19°C; the temperature in the fifth range is T5, where 19°C < T5 ≤ 28°C; the temperature in the sixth range is T6, where 28°C < T6 ≤ 35°C; the temperature in the seventh range is T7, where 35°C < T7 ≤ 40°C; the temperature in the eighth range is T8, where T8 > 40°C. Specifically, the ideal temperature ranges of the refrigerating chamber 11 and the freezing chamber 12 corresponding to different ambient temperature ranges and different operating modes are different. Thus, the temperature of the refrigerating chamber 11 and the freezing chamber 12 of the refrigerator 11 can be adaptively adjusted according to the actual ambient temperature to achieve better refrigerating and freezing functions.

[0098] Table 1 Ambient Temperature Range Table

[0099] Specifically, the range of the ambient temperature range is a value preset by humans. The ambient temperature ranges of different refrigerators 1 can be different, and the number of ambient temperature ranges of different refrigerators 1 can also be different.

[0100] Specifically, as shown in Table 2 and Table 3, each ambient temperature range corresponds to at least one refrigerating temperature range and at least one freezing temperature range. To enhance the functions of the refrigerator 1, each ambient temperature range can correspond to multiple refrigerating temperature ranges and multiple freezing temperature ranges. For example, the refrigerator 1 can include multiple working modes. In the refrigerating function, it can specifically include a quick-cooling mode, a strong gear mode, a medium gear mode, and a weak gear mode. Each working mode corresponds to its own refrigerating temperature range. Under the same working mode, the refrigerating temperature ranges corresponding to different ambient temperature ranges are at least partially different. Under different working modes corresponding to the same ambient temperature range, the refrigerating temperature ranges are at least partially different. In the freezing state, it can include a quick-freezing mode, a strong gear mode, a medium gear mode, and a weak gear mode. Each working mode corresponds to its own freezing temperature range. Under the same working mode, the freezing temperature ranges corresponding to different ambient temperature ranges are at least partially different. Under different working modes corresponding to the same ambient temperature range, the freezing temperature ranges are at least partially different.

[0105] The control method further includes:

[0106] S101, obtain the ambient temperature at which the refrigerator 1 is currently located, and obtain the current operating state of the refrigerator 1.

[0107] Specifically, the refrigerator 1 may further include an ambient temperature detection module for detecting the ambient temperature. The ambient temperature at which the refrigerator 1 is located can be obtained by the ambient temperature detection module and transmitted to the control system of the refrigerator 1 to determine the ambient temperature range corresponding to the ambient temperature through the control system.

[0108] Specifically, the current operating state of the refrigerator 1 is the working mode of the refrigerator 1, which can be selected manually.

[0109] S102, according to the ambient temperature and the current operating state of the refrigerator 1, determine the first shutdown temperature threshold Trt, the first startup temperature threshold Trk, the second shutdown temperature threshold Tft, and the second startup temperature threshold Tfk corresponding to the current operating state.

[0110] Specifically, taking the ambient temperature of -3°C as an example, it can be determined from Table 1 that the ambient temperature is within the range of the first interval. The first shutdown temperature thresholds Trt, the first startup temperature thresholds Trk, the second shutdown temperature thresholds Tft, and the second startup temperature thresholds Tfk under the eight working modes corresponding to the first interval are at least partially different.

[0111] When the user selects the refrigeration function: When the user selects the rapid cooling mode, the temperature within the refrigeration temperature range is Tc, where 2.5°C ≤ Tc ≤ 3°C. Therefore, the first shutdown temperature threshold Trt is 2.5°C and the first startup temperature threshold Trk is 3°C. When the user selects the high gear mode, the temperature within the refrigeration temperature range is Tc, where 2.5°C ≤ Tc ≤ 3.5°C. Therefore, the first shutdown temperature threshold Trt is 2.5°C and the first startup temperature threshold Trk is 3.5°C. When the user selects the medium gear mode, the temperature within the refrigeration temperature range is Tc, where 2.5°C ≤ Tc ≤ 3°C. Therefore, the first shutdown temperature threshold Trt is 2.5°C and the first startup temperature threshold Trk is 3°C. When the user selects the low gear mode, the temperature within the refrigeration temperature range is Tc, where 2.5°C ≤ Tc ≤ 3°C. Therefore, the first shutdown temperature threshold Trt is 2.5°C and the first startup temperature threshold Trk is 3°C. Taking the user's selection of the rapid cooling mode as an example, at this time, the preset refrigeration temperature range is from 2.5°C to 3°C, that is, the first shutdown temperature threshold Trt is 2.5°C and the first startup temperature threshold Trk is 3°C.

[0112] When the user selects the freezing function: When the user selects the quick-freezing working mode, the temperature within the freezing temperature range is Td, where -16°C ≤ Td ≤ -14°C. Therefore, the second shutdown temperature threshold Tft is -16°C and the second startup temperature threshold Tfk is -14°C. When the user selects the high gear mode, the temperature within the freezing temperature range is Td, where -17°C ≤ Td ≤ -15°C. Therefore, the second shutdown temperature threshold Tft is -17°C and the second startup temperature threshold Tfk is -15°C. When the user selects the medium gear mode, the temperature within the freezing temperature range is Td, where -18°C ≤ Td ≤ -16°C. Therefore, the second shutdown temperature threshold Tft is -18°C and the second startup temperature threshold Tfk is -16°C. When the user selects the low gear mode, the temperature within the freezing temperature range is Td, where -19°C ≤ Td ≤ -17°C. Therefore, the second shutdown temperature threshold Tft is -19°C and the second startup temperature threshold Tfk is -17°C. Taking the user's selection of the quick-freezing mode as an example, at this time, the preset freezing temperature range is from -16°C to -14°C, that is, the second shutdown temperature threshold Tft is -16°C and the second startup temperature threshold Tfk is -14°C.

[0113] After that, steps S200 and S400 are performed. That is, the first temperature is compared with the first shutdown temperature threshold Trt and the first startup temperature threshold Trk, and the heating system 14 is controlled to operate. Alternatively, the second temperature is compared with the second shutdown temperature threshold Tft and the second startup temperature threshold Tfk, and the refrigeration system 13 is controlled to operate.

[0114] In the above embodiment, the environmental temperature is partitioned to form environmental temperature ranges, so that different temperature regulations can be performed on the refrigerator 1 at different environmental temperatures. The refrigerator 1 is designed with different working modes, and the refrigeration and freezing effects / speeds of different working modes are different, so that it can be selected according to the user's preference. The above embodiment can achieve more accurate regulation of the refrigerating chamber 11 and the freezing chamber 12 to further improve the performance of the refrigerator 1.

[0115] In a feasible embodiment, when the first temperature sensing device 15 and the second temperature sensing device 16 are mechanical temperature control switches, the first temperature sensing device 15 is directly connected in series with the heating circuit, so that the first temperature sensing device 15 automatically turns on and off after sensing the temperature of the refrigerating chamber 11 to control the operation of the heating system 14, and the second temperature sensing device 16 is directly connected in series with the refrigeration circuit, so that the second temperature sensing device 16 automatically turns on and off after sensing the temperature of the freezing chamber 12 to control the operation of the refrigeration system 13.

[0116] In this embodiment, it is not necessary to detect and display the first temperature and the second temperature, nor is it necessary for the control component to control according to the detected first temperature or second temperature. It is only necessary for the first temperature sensing device 15 to turn on and off by itself after sensing the temperature of the refrigerating chamber 11 to control the state of the heating system 14, and for the second temperature sensing device 16 to turn on and off by itself after sensing the temperature of the freezing chamber 12 to control the state of the refrigeration system 13.

[0117] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
