TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of refrigeration. More particularly, to a refrigerator. BACKGROUND

[0002] The refrigerator can include a refrigeration chamber and a freezer chamber. At present, the temperature control method of the existing refrigeration chamber and freezer chamber is that when the temperature of the refrigeration chamber is too high, the compressor of the refrigerator drives the refrigerant to the evaporator of the refrigeration chamber and the evaporator of the freezer chamber, so that the temperature of the refrigeration chamber and the freezer chamber is reduced, and when the temperature requirement is met, the compressor stops running. However, when the ambient temperature is too low, the refrigeration chamber temperature will remain low for a long time, and thus the compressor cannot be triggered to run to cool the freezer chamber, and thus the freezer chamber temperature cannot meet the freezing requirement.

[0003] At present, in order to ensure that the compressor is triggered to run to cool the freezer chamber in time, a compensation heater is usually added in the refrigeration chamber, which heats the refrigeration chamber to quickly raise the temperature of the refrigeration chamber, so that the compressor can be triggered to start in time, and the temperature of the freezer chamber is reduced.

[0004] However, the above-mentioned compensation heater has high energy consumption, and is usually foamed in the cabinet of the refrigerator. When the compensation heater is foamed poorly or appears aging after a long time of heating, it will cause the refrigerator to burn, thus there is a safety hazard. SUMMARY

[0016] The first temperature response subunit is configured to, in response to the temperature in the refrigeration chamber being less than or equal to a preset refrigeration temperature, disconnect the circuit between the first electric control end of the drive unit;

[0017] The refrigeration chamber temperature response switch is configured to, in response to the temperature in the refrigeration chamber being less than or equal to a preset refrigeration temperature, close the refrigeration chamber temperature response switch;

[0018] The freezing chamber temperature response switch is configured to be closed in response to the temperature in the freezing chamber being greater than a preset freezing temperature.

[0019] In some embodiments of the present application, the refrigerating chamber temperature response switch and the freezing chamber temperature response switch are both temperature magnetic sensitive switches.

[0020] In some embodiments of the present application, the switch unit comprises a coil assembly and a first switch assembly.

[0042] In order to make the objects, implementation manners and advantages of the present application clearer, the following will clearly and completely describe the exemplary implementation manners of the present application with reference to the accompanying drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0043] It should be noted that the brief descriptions of the terms in the present application are only for the convenience of understanding the following described embodiments, and are not intended to limit the implementation manners of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0044] In addition, the terms “include” and “have” and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to the clearly listed components, but can include other components not clearly listed or inherent to these products or devices.

[0045] The refrigeration mode of the refrigerator can generally be divided into direct-cooling refrigeration, air-cooling refrigeration, etc. Taking the direct-cooling refrigeration as an example, Figure 1 A structural schematic diagram of a refrigerator refrigeration control system provided in the prior art is shown in FIG. 4. As shown in the figure, the refrigeration control system can include a power plug 11, a light switch 12, a light-emitting diode (LED) lighting module 13, a temperature controller 14, a temperature compensation switch 15, a compensation heater 16, an overload protector 17, a compressor 18, a running capacitor 19, and a starter 110. Figure 1

[0046] After the power plug 11 is plugged into the power supply, the refrigeration control system can be powered. The refrigerator can include a refrigeration chamber and a freezer chamber. Generally, when the refrigerator refrigeration chamber is switched on, the light switch 12 is closed to trigger the LED lighting module to light up. The overload protector 17, the running capacitor 19, and the starter 110 are used to ensure the safe operation of the compressor 18.

[0047] ​Currently, the existing method for controlling the temperature of the refrigerator and freezer compartments is that when the temperature of the refrigerator compartment is too high, the thermostat 14 can open the power supply circuit between the power supply and the compressor 18, so that the compressor 18 can drive refrigerant to the evaporators of the refrigerator and freezer compartments, thereby reducing the temperature of the refrigerator and freezer compartments. When the temperature of the refrigerator compartment reaches a lower state, the compressor 18 stops operating.

[0048] However, when the ambient temperature is too low, the temperature of the refrigerator compartment will remain low for a long time, and the compressor 18 cannot be triggered to run. Therefore, the compressor 18 cannot refrigerate the freezer compartment for a long time, resulting in a high temperature in the freezer compartment and unable to meet the freezing requirements.

[0049] At present, in order to ensure that the compressor 18 is triggered in time to cool the freezer compartment, a compensation heater 16 is mainly installed in the refrigerator compartment. When the temperature compensation switch 15 is closed, the refrigerator compartment can be heated by the compensation heater 16 to quickly increase the temperature of the refrigerator compartment, thereby triggering the compressor 18 to start in time and lowering the temperature of the freezer compartment.

[0050] However, the energy consumption of the above-mentioned compensating heater 18 is high, and it is usually foamed in the cabinet of the refrigerator. When the compensating heater 18 foams poorly or ages due to long-term heating, it can cause the refrigerator to burn, so there is a potential safety hazard.

[0051] Taking into account the above-mentioned problems existing in existing refrigerators, the present application proposes a method that does not require a compensating heater and can ensure timely refrigeration of the freezer compartment of the refrigerator, so as to improve the safety of refrigerator use and reduce the energy consumption of the refrigerator.

[0052] The refrigerator provided in this application may include a refrigerator compartment, a freezer compartment, and a refrigeration system. Figure 2 This is a schematic diagram of the structure of a refrigerator refrigeration system provided in this application. Figure 2 As shown, the refrigeration system 20 may include a refrigeration module 21 and a control module 22 . The refrigeration module 21 may include a driving unit 211 , a flow diversion unit 212 , and a refrigeration unit 213 .

[0053] The refrigerant output end of the driving unit 211 can be connected to the refrigerant input end of the diverter unit 212. The refrigerant output end of the diverter unit 212 can be connected to the refrigeration unit 213. The electrical control end of the diverter unit 212 can be connected to the control module 22.

[0054] The driving unit 211 can be used to drive the refrigerant to the diversion unit 212 .

[0055] Optionally, the driving unit 211 can be any driving device capable of driving the refrigerant to the distribution unit 212, such as a compressor.

[0056] Optionally, the distribution unit 212 can be an electromagnetic valve. By energizing or de-energizing the electromagnetic valve, the electromagnetic valve can distribute the refrigerant from the driving unit 211 in different ways. Alternatively, the distribution unit 212 can also be other types of valves capable of distributing the refrigerant.

[0057] Optionally, the refrigerating unit 213 can refer to any existing refrigerating device. For example, the refrigerating unit 213 can include a refrigerating chamber evaporator and a freezing chamber evaporator, and a capillary tube, etc.

[0058] The control module 22 can control the distribution unit 212 to distribute the refrigerant so that the refrigerating unit 213 refrigerates the freezing chamber and stops refrigerating the refrigerating chamber, in response to the temperature in the refrigerating chamber being less than or equal to a preset refrigerating temperature and the temperature in the freezing chamber being greater than a preset freezing temperature.

[0059] Optionally, the refrigerating chamber and the freezing chamber of the refrigerator can each be provided with a temperature detecting component. The temperature detecting component in the refrigerating chamber can detect the temperature in the refrigerating chamber, and the temperature detecting component in the freezing chamber can detect the temperature in the freezing chamber. The control module 22 can acquire the temperature in the refrigerating chamber and the temperature in the freezing chamber, and determine whether the temperature in the refrigerating chamber is less than or equal to a preset refrigerating temperature and whether the temperature in the freezing chamber is greater than a preset freezing temperature. For example, the control module 22 can execute the above determination steps through a software control logic program, and control the distribution unit 212 to distribute the refrigerant so that the refrigerating unit 213 refrigerates the freezing chamber and stops refrigerating the refrigerating chamber. Alternatively, the control module 22 can also control the distribution unit 212 to distribute the refrigerant in response to the temperature in the refrigerating chamber being less than or equal to a preset refrigerating temperature and the temperature in the freezing chamber being greater than a preset freezing temperature based on a temperature response component (such as a temperature magnetic sensitive switch, etc.).

[0060] When the temperature in the refrigerating chamber is less than or equal to a preset refrigerating temperature, it means that the temperature in the refrigerating chamber has met the temperature requirement for refrigeration. When the temperature in the freezing chamber is greater than a preset freezing temperature, it means that the temperature in the freezing chamber is too high and does not meet the temperature requirement for freezing. By refrigerating the freezing chamber and stopping refrigerating the refrigerating chamber, the temperature in the freezing chamber can be reduced to meet the temperature requirement for freezing, and the temperature in the refrigerating chamber will not be too low to meet the temperature requirement for refrigeration, thereby improving the flexibility of temperature control.

[0061] In the embodiment, the refrigerant can be driven to the distribution unit 212 by the driving unit 211. When the temperature in the refrigeration chamber is less than or equal to the preset refrigeration temperature, and the temperature in the freezing chamber is greater than the preset freezing temperature, the distribution unit 212 can be controlled to distribute the refrigerant, so that the refrigeration unit 213 refrigerates the freezing chamber, and the refrigeration of the refrigeration chamber is stopped. By the above method, the compensating heater is avoided to be arranged in the refrigerator, the safety of the refrigerator is improved, and the energy consumption of the refrigerator is reduced. When the temperature in the refrigeration chamber meets the temperature demand of the refrigeration, and the temperature in the freezing chamber is too high to meet the temperature demand of the refrigeration, the refrigerator can refrigerate the freezing chamber alone, and the refrigeration of the refrigeration chamber is stopped, so that the temperature in the freezing chamber is reduced to meet the temperature demand of the refrigeration, and the temperature in the refrigeration chamber is not too low to meet the temperature demand of the refrigeration, and the flexibility of the temperature control is improved.

[0062] The structure of the control module 22 will be described in detail below.

[0063] Taking the refrigeration unit 213 including the refrigeration sub-unit for the refrigeration chamber and the refrigeration sub-unit for the freezing chamber as an example, Figure 3 Another structure of a refrigerator refrigeration control system provided by the present application is shown in the figure. Figure 3 As a possible implementation, the control module 22 can include a temperature response unit 31 and a switch unit 32.

[0064] The first end of the temperature response unit 31 can be connected to the first end of the power supply 33. The second end of the temperature response unit 31 can be connected to the first control end of the driving unit 211 and the first end of the switch unit 32. The third end of the temperature response unit 31 and the second end of the switch unit 32 can be connected to the first control end of the distribution unit 212. The third end of the switch unit 32, the second control end of the distribution unit 212, and the second control end of the driving unit 211 can be connected to the second end of the power supply 33.

[0065] The temperature response unit 31 can be used to respond to the temperature in the refrigeration chamber being less than or equal to the preset refrigeration temperature, and the temperature in the freezing chamber being greater than the preset freezing temperature, to turn on the power supply circuit of the distribution unit 212, and trigger the switch unit 32 to turn on the first power supply circuit of the driving unit 211.

[0066] The temperature response unit 31 may, for example, be capable of detecting the temperature in the refrigerator and the temperature in the freezer, and performing the operation of "in response to the temperature in the refrigerator being less than or equal to a preset refrigerator temperature, and the temperature in the freezer being greater than a preset freezer temperature, switching on the power supply circuit of the shunt unit 212, and triggering the switch unit 32 to switch on the first power supply circuit of the drive unit 211." Alternatively, the temperature response unit 31 may also detect the temperature in the refrigerator and the temperature in the freezer via a temperature detection component connected to the temperature response unit 31.

[0067] The first power supply circuit may be, for example, a power supply circuit starting from the first end of the power supply 33 , sequentially passing through the temperature response unit 31 , the switch unit 32 , the drive unit 211 , and reaching the second end of the power supply 33 .

[0068] When the power supply circuit (eg, the first power supply circuit) of the driving unit 211 is turned on, the driving unit 211 can be used to drive the refrigerant to the diversion unit 212 .

[0069] When the power supply circuit of the shunt unit 212 is on, the shunt unit 212 can be used to transfer the refrigerant from the drive unit 211 to the freezer compartment refrigeration sub-unit and stop transferring the refrigerant to the refrigerator compartment refrigeration sub-unit. By transferring the refrigerant to the freezer compartment refrigeration sub-unit, the freezer compartment can be cooled using the refrigerant. By stopping transferring the refrigerant to the refrigerator compartment refrigeration sub-unit, the refrigerator compartment can be stopped from being cooled.

[0070] In this embodiment, the switch unit 32 can be used to control the on / off state of the first power supply circuit of the drive unit 211. The temperature response unit 31 can respond to the temperature in the refrigerator compartment and the temperature in the freezer compartment to turn on the power supply circuit of the diversion unit 212 and trigger the switch unit 32 to turn on the first power supply circuit of the drive unit 211, so that the refrigerant cools the freezer compartment and stops cooling the refrigerator compartment.

[0071] The structures of the temperature response unit 31 and the switch unit 32 are exemplarily described below:

[0072] For example, Figure 4 This is a schematic diagram of the structure of a temperature response unit 31 provided in this application. Figure 4 As shown, in some embodiments, the temperature response unit 31 may include, for example, a first temperature response subunit 41 and a second temperature response subunit 42. The second temperature response subunit 42 may include, for example, a refrigerator compartment temperature response switch 421 and a freezer compartment temperature response switch 422.

[0073] The first end of the first temperature responsive sub-unit 41 can be connected to the power source 33. The second end of the first temperature responsive sub-unit 41 can be connected to the first end of the refrigerating chamber temperature responsive switch 421. The second end of the refrigerating chamber temperature responsive switch 421 can be connected to the first end of the freezing chamber temperature responsive switch 422. The second end of the freezing chamber temperature responsive switch 422 and the second end of the switch unit 32 can be connected to the first electrically controlled end of the shunt unit 212. The third end of the first temperature responsive sub-unit 41 can be connected to the first electrically controlled end of the driving unit 211 and the first end of the switch unit 32.

[0074] The first temperature responsive sub-unit 41 can be configured to disconnect the circuit between the first electrically controlled end of the driving unit 211 in response to the temperature in the refrigerating chamber being less than or equal to a preset refrigerating temperature.

[0075] For example, the first temperature responsive sub-unit 41 can be any existing switch type that can be responsive to temperature change to disconnect or close. For example, the first temperature responsive sub-unit 41 can be the temperature controller 14 as described in the foregoing embodiments.

[0076] The refrigerating chamber temperature responsive switch 421 can be configured to close the refrigerating chamber temperature responsive switch 421 in response to the temperature in the refrigerating chamber being less than or equal to a preset refrigerating temperature. The freezing chamber temperature responsive switch 422 can be configured to close the freezing chamber temperature responsive switch 422 in response to the temperature in the freezing chamber being greater than a preset freezing temperature.

[0077] Optionally, the refrigerating chamber temperature responsive switch 421 and the freezing chamber temperature responsive switch 422 can be of the same type or different types, which are not limited in the present application. Optionally, the refrigerating chamber temperature responsive switch 421 and the freezing chamber temperature responsive switch 422 can be any existing switch type that can be responsive to temperature change to close or disconnect.

[0078] For example, the refrigerating chamber temperature responsive switch 421 and the freezing chamber temperature responsive switch 422 can each be a temperature magnetic sensitive switch. That is, the refrigerating chamber can correspond to one temperature magnetic sensitive switch as the refrigerating chamber temperature responsive switch. In addition, the freezing chamber can correspond to another temperature magnetic sensitive switch as the freezing chamber temperature responsive switch.

[0079] For example, the temperature magnetic sensitive switch can include a soft magnetic material. The Curie point of the soft magnetic material is designed to be near the desired controlled temperature point. Since the magnetic permeability of the material changes sharply near the Curie point, the air gap magnetic field near the reed switch contacts of the temperature magnetic sensitive switch changes sharply, thereby controlling the closing and disconnecting of the two reeds. It should be understood that the structure of the temperature magnetic sensitive switch can refer to any existing temperature magnetic sensitive switch, which is not limited in the present application.

[0080] For example, the preset refrigeration temperature and the preset freezing temperature can be adjusted by setting parameters of the temperature magnetic switch. For example, the temperature magnetic switch of the refrigeration chamber can be turned on when the temperature in the refrigeration chamber is less than or equal to 8°C, and turned off when the temperature in the refrigeration chamber is greater than 12°C. The temperature magnetic switch of the freezing chamber can be turned off when the temperature in the freezing chamber is less than or equal to -18°C, and turned on when the temperature in the freezing chamber is greater than -15°C.

[0081] For example, Figure 5 A schematic diagram of a switch unit 32 is provided in the present application. As shown in some embodiments, the switch unit 32 can include a coil assembly 51 and a first switch assembly 52. Figure 5 The first end of the first switch assembly 52 can be connected to the second end of the temperature response unit 31 and the first control end of the driving unit 211. The second end of the first switch assembly 52 can be connected to the first end of the coil assembly 51 and the first control end of the shunt unit 212 (the first control end of the shunt unit 212 is also connected to the third end of the temperature response unit). The second end of the coil assembly 51 can be connected to the second control end of the shunt unit 212 and the second control end of the driving unit 211.

[0082] For example, the coil assembly 51 of the switch unit 32 can be a relay coil, and the first switch assembly 52 of the switch unit 32 can be a relay contact.

[0083] For example, the coil assembly 51 of the switch unit 32 can be a relay coil, and the first switch assembly 52 of the switch unit 32 can be a relay contact.

[0084] Optionally, the temperature response unit 31 can be used to energize the coil assembly 51 in response to the temperature in the refrigeration chamber being less than or equal to the preset refrigeration temperature and the temperature in the freezing chamber being greater than the preset freezing temperature. The energization of the coil assembly 51 can cause the first switch assembly 52 to close. When the temperature response unit 31 does not energize the coil assembly 51, that is, when the coil assembly 51 is not energized, the first switch assembly 52 is open.

[0085] For example, the temperature response unit 31 can turn on the power supply circuit between the power supply 33 and the coil assembly 51 in response to the temperature in the refrigeration chamber being less than or equal to the preset refrigeration temperature and the temperature in the freezing chamber being greater than the preset freezing temperature, so that the power supply 33 energizes the coil assembly 51, thereby causing the first switch assembly 52 to close and realizing the first power supply circuit between the power supply 33 and the driving unit 211.

[0086] Through the switch unit 32, the first switch unit 52 can be controlled to be opened or closed in response to the operation of the temperature response unit 31 on whether to supply power to the coil assembly 51, thereby laying a foundation for controlling whether the first power supply circuit of the driving unit 211 is turned on.

[0087] In some embodiments, the temperature response unit 31 can also be configured to, in response to the temperature in the refrigerating chamber being greater than the preset refrigerating temperature, disconnect the power supply circuit of the shunt unit 212 and turn on the second power supply circuit between the power supply 33 and the driving unit 211, and trigger the switch unit 32 to disconnect the first power supply circuit of the driving unit 211.

[0088] The second power supply circuit between the power supply 33 and the driving unit 211 can be, for example, a power supply circuit that starts from the power supply 33, passes through the temperature response unit 31 and the driving unit 211, and then reaches the other end of the power supply 33.

[0089] When the power supply circuit of the shunt unit 212 is disconnected, the shunt unit 212 can be configured to deliver the refrigerant from the driving unit 211 to the refrigerating chamber refrigeration subunit and the refrigerating chamber refrigeration subunit, so that both the refrigerating chamber and the freezing chamber are refrigerated.

[0090] When the temperature in the refrigerating chamber is greater than the preset refrigerating temperature, it means that the temperature in the refrigerating chamber is too high. Through the above method, the driving unit is started to refrigerate the refrigerating chamber and the freezing chamber when the temperature in the refrigerating chamber does not meet the refrigerating temperature requirement.

[0091] In some embodiments, the temperature response unit 31 can also be configured to, in response to the temperature in the refrigerating chamber being less than or equal to the preset refrigerating temperature and the temperature in the freezing chamber being less than or equal to the preset freezing temperature, disconnect the second power supply circuit between the power supply 33 and the driving unit 211, and trigger the switch unit 32 to disconnect the first power supply circuit of the driving unit 211, so that neither the refrigerating chamber nor the freezing chamber is refrigerated.

[0092] When the temperature in the refrigerating chamber is less than or equal to the preset refrigerating temperature, it means that the temperature in the refrigerating chamber meets the refrigerating requirement. When the temperature in the freezing chamber is less than or equal to the preset freezing temperature, it means that the temperature in the freezing chamber meets the freezing requirement. Through the above method, when the temperature in the refrigerating chamber has met the refrigerating requirement and the temperature in the freezing chamber has met the freezing requirement, the refrigerating chamber and the freezing chamber are no longer refrigerated, so that the temperature of the refrigerating chamber and the freezing chamber will not be further reduced, thereby improving the stability of the refrigerator refrigeration.

[0093] In some embodiments, the control module 22 can also be configured to, in response to the temperature in the refrigerating chamber being greater than the preset refrigerating temperature and the temperature in the freezing chamber being less than or equal to the preset freezing temperature, control the shunt unit to shunt the refrigerant, so that the refrigeration unit refrigerates the refrigerating chamber and stops refrigerating the freezing chamber.

[0094] The structure of the above refrigeration module 21 will be described as follows:

[0095] As mentioned above, the refrigeration module 21 can comprise a refrigeration unit 213, and the refrigeration unit 213 can comprise a refrigeration subunit for a refrigeration chamber and a refrigeration subunit for a freezing chamber. For example, Figure 6 A structure diagram of a refrigeration unit 213 is provided in the present application. As Figure 6 shown, in some embodiments, the refrigeration subunit for a refrigeration chamber 61 can comprise a refrigeration chamber evaporator 611 and a first capillary tube 612. The refrigeration subunit for a freezing chamber 62 can comprise a freezing chamber evaporator 621 and a second capillary tube 622.

[0096] The refrigerant output end of the distribution unit 212 can be connected to the first end of the first capillary tube 612 (i.e. the refrigerant input end of the first capillary tube) and the first end of the second capillary tube 622 (i.e. the refrigerant input end of the second capillary tube). The second end of the first capillary tube 612 (i.e. the refrigerant output end of the first capillary tube) can be connected to the first end of the refrigeration chamber evaporator 611 (i.e. the refrigerant input end of the refrigeration chamber evaporator 611). The second end of the refrigeration chamber evaporator 611 can be connected to the second end of the second capillary tube 622 (i.e. the refrigerant output end of the second capillary tube) and the first end of the freezing chamber evaporator 621 (i.e. the refrigerant input end of the freezing chamber evaporator 621). The second end of the freezing chamber evaporator 621 is connected to the driving unit 211.

[0097] The refrigeration chamber evaporator 611 and the freezing chamber evaporator 621 can be any existing evaporator of a refrigerator, which will not be described herein. The first capillary tube 612 and the second capillary tube 622 can be any existing capillary tube of a refrigerator, which will not be described herein.

[0098] It should be understood that the present application does not limit whether the refrigeration unit 213 comprises other components. For example, the refrigerant output end of the driving unit 211 and the distribution unit 212 can further comprise a condenser, a drying filter and the like.

[0099] For example, for refrigeration for the freezing chamber and stopping refrigeration for the refrigeration chamber, the distribution unit 212 can transmit the refrigerant to the second capillary tube 622, so that the refrigerant can be transmitted to the freezing chamber evaporator 621 only and refrigerate the freezing chamber through the freezing chamber evaporator 621. The distribution unit 212 can close the valve to the first capillary tube 612 to stop the refrigerant from being delivered to the first capillary tube 612, so that the refrigeration chamber evaporator 611 does not refrigerate the refrigeration chamber.

[0100] Taking the example of cooling both the refrigerator and freezer compartments, the diversion unit 212 can, for example, transfer the refrigerant to the second capillary tube 622 and the first capillary tube 612, so that the refrigerant can be transferred from the second capillary tube 622 to the freezer compartment evaporator 621 and from the first capillary tube 612 to the refrigerator compartment evaporator 611. Thus, the freezer compartment can be cooled by the freezer compartment evaporator 621, and the refrigerator compartment can be cooled by the refrigerator compartment evaporator 611.

[0101] The following uses the example of the refrigerator compartment temperature response switch and the freezer compartment temperature response switch being both temperature magnetic switches as an example to illustrate the structure of the refrigerator provided by the present application:

[0102] For example, Figure 7 This is a schematic diagram of the structure of a refrigerator provided in this application. Figure 7 As shown, the refrigerator compartment 71 of the refrigerator 70 may correspond to a refrigerator compartment evaporator 611 and a refrigerator compartment temperature magnetic switch 72. The freezer compartment 81 of the refrigerator 70 may correspond to a freezer compartment evaporator 621 and a freezer compartment temperature magnetic switch 82.

[0103] Take the above-mentioned shunt unit as an AC solenoid valve as an example, Figure 8 This is a schematic diagram of the structure of a refrigerator refrigeration control system provided by this application. Figure 8 As shown, the temperature magnetic switch 91 can be a refrigerator temperature magnetic switch; the temperature magnetic switch 92 can be a freezer temperature magnetic switch. The switch 93 can be the aforementioned relay contact. The AC solenoid valve 94 can be the aforementioned shunt unit 212. Figure 8 The remaining components shown in can refer to the aforementioned embodiments and will not be described again here.

[0104] by Figure 8 Taking the refrigeration system shown as an example, when the temperature of the refrigerator compartment is too high, the thermostat 14 is turned on, the compressor 18 works, the refrigerator compartment temperature magnetic switch 91 is disconnected, the freezer compartment temperature magnetic switch 92 is turned on, the AC solenoid valve 94 does not work, and the refrigerator compartment and the freezer compartment are cooled at the same time.

[0105] When the refrigerator compartment temperature meets the required level, the thermostat 14 turns off, the refrigerator compartment temperature magnetic switch 91 turns on, and the freezer compartment temperature magnetic switch 92 senses the freezer compartment temperature. If the freezer compartment temperature is higher than the set value, the freezer compartment temperature magnetic switch 92 turns on, energizing the relay coil 95, and the compressor 18 continues to operate. Simultaneously, the AC solenoid valve 94 operates, switching the refrigeration circuit so that the refrigerator compartment stops cooling and the freezer compartment cools. If the freezer compartment temperature falls below the set value, the freezer compartment temperature magnetic switch 92 turns off, energizing the relay coil 95, and the compressor 18 stops operating, resulting in neither the refrigerator nor the freezer compartment cooling. If the refrigerator compartment temperature rises again to a level too high, the refrigerator compartment temperature magnetic switch 91 turns off, de-energizing the AC solenoid valve 94, and both the refrigerator and freezer compartments cool again.

[0106] In the embodiment, by adding temperature magnetic switches in the refrigerating chamber and the freezing chamber of the refrigerator, whether the temperature of the refrigerating chamber and the temperature of the freezing chamber meet the requirements is sensed, and the control system of the refrigerator is controlled by the temperature magnetic switches of the two chambers to control the refrigeration of the refrigerating chamber and the freezing chamber respectively, so that the temperature of the refrigerating chamber and the temperature of the freezing chamber can meet the requirements, the stability and flexibility of refrigeration are improved, and the user experience is improved. Through the above method, the refrigeration chamber does not need to be provided with a compensation heater, the safety of the refrigerator is improved, and the temperature of the freezing chamber can also meet the freezing requirements when the ambient temperature is low.

[0107] The application further provides a computer readable storage medium, which can include a U disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, and various storage program code mediums, and specifically, the computer readable storage medium stores program instructions, and the program instructions are used for the method in the above embodiments.
