Description

Technical Field

[0001] Embodiments of the present application relate to the technical field of household appliances. More specifically, it relates to a refrigerator, a control method of the refrigerator, and a storage medium. Background Art

[0002] When the refrigerator is refrigerating, moisture in the circulating air will frost on the evaporator and the connecting pipeline.

[0003] Currently, during the refrigeration process, air circulates from the bottom of the evaporator, which easily causes more frosting at the bottom. Especially when the humidity of the environment where the refrigerator is located is high, frost blockage is likely to occur at the bottom of the evaporator, resulting in blockage of the evaporator and reducing the refrigeration efficiency of the refrigerator. Then, how to prevent excessive frosting at the bottom of the evaporator and improve the refrigeration efficiency of the refrigerator is an urgent problem to be solved. Summary of the Invention

[0004] Embodiments of the present application provide a refrigerator, a control method of the refrigerator, and a storage medium, which can be used to prevent excessive frosting at the bottom of the evaporator and increase the refrigeration efficiency of the refrigerator.

[0005] In a first aspect, embodiments of the present application provide a refrigerator, which includes:

[0007] A refrigeration system disposed in the box body, including: a compressor, a condenser, a first evaporator corresponding to the freezing chamber, a second evaporator corresponding to the refrigerating chamber, and a first blower corresponding to the refrigerating chamber;

[0008] Wherein, the compressor is respectively communicated with the condenser and the first evaporator, and a first electromagnetic valve is arranged between the compressor and the condenser and the first evaporator. The first electromagnetic valve is configured to control the refrigerant flowing out of the compressor to flow to the condenser when the refrigeration system is in the refrigeration mode;

[0009] The condenser is respectively communicated with the first evaporator and the second evaporator, and a second electromagnetic valve is arranged between the condenser and the first evaporator and the second evaporator. The second electromagnetic valve is configured to control the refrigerant flowing out of the condenser to flow to the first evaporator and / or the second evaporator;

[0010] The inlet of the first evaporator is communicated with the outlet of the second evaporator through a preset pipeline. A part of the preset pipeline is arranged in a zigzag manner at the bottom of the first evaporator, and the refrigerant flowing out of the second evaporator flows through the bottom of the first evaporator and then flows into the first evaporator;

[0011] The refrigerator further includes a control component electrically connected to the refrigeration system, configured to:

[0012] When it is determined to start the refrigeration mode, obtain a first humidity value of the environment where the refrigerator is located;

[0013] If the first humidity value is above a preset humidity value, control the compressor to start, and control the refrigerant flowing out of the condenser to flow to the second evaporator through the second solenoid valve;

[0014] Control the first blower to operate at a first speed, and the first speed is greater than the preset speed of the first blower when in the refrigeration mode;

[0015] Control the refrigerant flowing out of the condenser to flow to the first evaporator through the second solenoid valve.

[0016] In this embodiment, the compressor is respectively connected to the condenser and the first evaporator. A first solenoid valve is provided between the compressor and the condenser and the first evaporator, and is used to control the refrigerant flowing out of the compressor to flow to the condenser when the refrigeration system is in the refrigeration mode. The condenser is respectively connected to the first evaporator and the second evaporator. A second solenoid valve is provided between the condenser and the first evaporator and the second evaporator. The second solenoid valve is configured to control the refrigerant flowing out of the condenser to flow to the first evaporator and / or the second evaporator. The inlet of the first evaporator is connected to the outlet of the second evaporator through a preset pipeline. Wherein, part of the pipeline of the preset pipeline is tortuously arranged at the bottom of the first evaporator, and the refrigerant flowing out of the second evaporator flows through the bottom of the first evaporator to the first evaporator. The control component is configured to obtain the first humidity value of the environment where the refrigerator is located when it is determined to start the refrigeration mode. If the first humidity value is above the preset humidity value, the compressor can be controlled to start, and the refrigerant flowing out of the condenser can be controlled to flow to the second evaporator through the second solenoid valve. Then control the first blower to operate at the first speed, and control the refrigerant flowing out of the condenser to flow to the first evaporator through the second solenoid valve. In this application, the refrigerant entering the first evaporator from the second evaporator relieves the frost layer condensed at the bottom of the first evaporator during the refrigeration of the freezer compartment when passing through the bottom of the first evaporator, preventing excessive frosting at the bottom of the first evaporator.

[0017] In some embodiments of the present application, the refrigerator further includes a second blower, and the second blower is configured to allow air to enter the first evaporator for heat exchange and send the air after heat release into the freezer compartment;

[0018] The control component is configured to:

[0019] Control the second blower to operate at the first speed.

[0020] In this embodiment, after the fan in the refrigerating chamber is turned on, since the refrigerating evaporator pipeline is arranged at the bottom of the freezing evaporator, the bottom temperature is relatively high. At this time, the rotation speed of the freezing fan is controlled to operate at the first rotation speed, so that when the air passes through the freezing evaporator for cooling, it can quickly reach the upper part of the freezing evaporator to condense into frost, thereby realizing uniform frosting.

[0021] In some embodiments of the present application, the control component is configured to:

[0022] After the first preset duration of this refrigeration is completed, obtain the second humidity value of the environment where the refrigerator is located;

[0023] If the second humidity value is greater than the preset humidity value, control the first fan to operate at the second rotation speed, and the second rotation speed is less than the first rotation speed.

[0024] In this embodiment, after the refrigerator is in a high humidity environment for more than a certain duration, the frosting amount of the first evaporator gradually increases. The rotation speed of the first fan can be reduced, so that the temperature of the pipeline at the bottom of the first evaporator is reduced, and thus frosting can occur in the middle of the first evaporator.

[0025] In some embodiments of the present application, the control component is configured to:

[0026] After the first preset duration when the rotation speed of the first fan is adjusted to the second rotation speed, obtain the third humidity value of the environment where the refrigerator is located;

[0027] If the third humidity value is greater than the preset humidity value, control the first fan to operate at the third rotation speed, and the third rotation speed is less than the second rotation speed.

[0028] In this embodiment, after the refrigerator is in a high humidity environment for a certain duration again, the rotation speed of the first fan can be reduced again, so that the temperature of the pipeline at the bottom of the first evaporator is reduced again, and the wet air at the bottom position of the first evaporator can quickly frost and condense at the bottom of the first evaporator.

[0029] In some embodiments of the present application, the first solenoid valve is further configured to control the refrigerant flowing out of the compressor to flow to the first evaporator in the defrosting mode;

[0030] The control component is configured to:

[0031] When it is determined to start the defrosting mode, through the first solenoid valve, control the refrigerant flowing out of the compressor to flow to the first evaporator, so that the refrigerant flowing out of the compressor passes through the first evaporator and then flows to the second evaporator;

[0032] The refrigerant flowing out of the second evaporator is controlled to flow to the condenser through the second solenoid valve.

[0033] In this embodiment, the reverse flow of the refrigerant can be achieved through the first solenoid valve, so that the refrigerant flows from the first evaporator, through the second evaporator to the condenser, and finally to the compressor to achieve defrosting.

[0034] In some embodiments of the present application, the first solenoid valve includes an exhaust port, an intake port, a first outlet, and a second outlet;

[0035] The condenser is connected to the first outlet through a first pipeline, and the first evaporator is connected to the second outlet through a second pipeline;

[0036] When the refrigeration system is in the refrigeration mode, the refrigerant flowing out of the compressor enters the condenser through the exhaust port and the first outlet;

[0037] When the refrigeration system is in the defrosting mode, the refrigerant flowing out of the compressor enters the first evaporator through the exhaust port and the second outlet.

[0038] In this embodiment, the reverse flow of the refrigerant can be achieved through the first solenoid valve.

[0039] In some embodiments of the present application, the second evaporator is connected to the second solenoid valve through a third pipeline, and the first evaporator is connected to the second solenoid valve through a fourth pipeline; wherein, capillary tubes are respectively arranged on the third pipeline and the fourth pipeline.

[0040] In this embodiment, capillary tubes can be arranged on the pipeline between the condenser and the first evaporator, and on the pipeline between the condenser and the second evaporator to achieve throttling and pressure reduction.

[0041] In some embodiments of the present application, the storage compartment further includes a variable temperature compartment; the refrigeration system further includes a third evaporator, and the inlet of the third evaporator is connected to the second solenoid valve through a fifth pipeline, so that when the variable temperature compartment is refrigerated, the refrigerant flowing out of the condenser is controlled to flow to the third evaporator through the second solenoid valve, and the third evaporator is configured to provide cold for the variable temperature compartment;

[0042] The outlet of the third evaporator is connected to the inlet of the first evaporator, so that when the variable temperature compartment is refrigerated, the refrigerant flowing out of the third evaporator flows through the first evaporator to the compressor.

[0043] In this embodiment, if the refrigerator is further provided with a variable temperature compartment, when the variable temperature compartment is refrigerated, the refrigerant flowing out of the third evaporator can be made to flow to the first evaporator to achieve refrigeration for the variable temperature compartment and the freezer compartment.

[0044] In a second aspect, the present application provides a control method for a refrigerator, where the refrigerator includes:

[0045] a box body provided with a storage compartment, and the storage compartment includes a refrigerating compartment and a freezing compartment;

[0046] a refrigeration system disposed in the box body, including: a compressor, a condenser, a first evaporator corresponding to the freezing compartment, a second evaporator corresponding to the refrigerating compartment, and a first blower corresponding to the refrigerating compartment;

[0047] Wherein, the compressor is respectively communicated with the condenser and the first evaporator, and a first electromagnetic valve is arranged between the compressor and the condenser and the first evaporator, and the first electromagnetic valve is configured to control the refrigerant flowing out of the compressor to flow to the condenser when the refrigeration system is in a refrigeration mode;

[0048] The condenser is respectively communicated with the first evaporator and the second evaporator, and a second electromagnetic valve is arranged between the condenser and the first evaporator and the second evaporator, and the second electromagnetic valve is configured to control the refrigerant flowing out of the condenser to flow to the first evaporator and / or the second evaporator;

[0049] The inlet of the first evaporator is communicated with the outlet of the second evaporator through a preset pipeline, and a part of the pipeline of the preset pipeline is arranged in a zigzag manner at the bottom of the first evaporator, and the refrigerant flowing out of the second evaporator flows to the first evaporator through the bottom of the first evaporator;

[0050] The method includes:

[0051] When it is determined to start the refrigeration mode, obtain a first humidity value of the environment where the refrigerator is located;

[0052] If the first humidity value is above a preset humidity value, control the compressor to start, and control the refrigerant flowing out of the condenser to flow to the second evaporator through the second electromagnetic valve;

[0053] Control the first blower to operate at a first speed, and the first speed is greater than a preset speed of the first blower when it is in the refrigeration mode;

[0054] Control the refrigerant flowing out of the condenser to flow to the first evaporator through the second electromagnetic valve.

[0055] In this embodiment, when it is determined to start the refrigeration mode, the first humidity value of the environment where the refrigerator is located is obtained. If the first humidity value is greater than the preset humidity value, the compressor can be controlled to start, and the refrigerant flowing out of the condenser is controlled by the second solenoid valve to flow to the second evaporator. Then, the first blower is controlled to operate at the first rotation speed, and the refrigerant flowing out of the condenser is controlled by the second solenoid valve to flow to the first evaporator. In this application, when the refrigerant entering the first evaporator from the second evaporator passes through the bottom of the first evaporator, the frost layer condensed at the bottom of the first evaporator during the refrigeration of the freezer compartment is alleviated, preventing excessive frosting at the bottom of the first evaporator.

[0081] To make the purpose, 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 of the embodiments.

[0082] It should be noted that the brief description of terms in this application is only for facilitating the understanding of the following-described embodiments, rather than intending to limit the embodiments of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0083] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover but not exclusively include. For example, a product or device comprising a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0084] During the refrigeration process of a refrigerator, since moisture in the circulating air will frost on the evaporator and the connected pipelines, and in the related art, only during the defrosting process can the frost layer on the evaporator be melted to achieve defrosting. Exemplarily, for example, a defrost heating wire is provided at the bottom of the evaporator to achieve defrosting of the evaporator by the defrost heater when the defrosting is turned on. However, this method has problems such as an increase in the energy consumption of the refrigerator.

[0085] During the refrigeration process, air circulates from the bottom of the evaporator, which easily causes more frosting at the bottom. Especially when the humidity of the environment where the refrigerator is located is high, frost blockage is likely to occur at the bottom of the evaporator, resulting in blockage of the evaporator and a reduction in the refrigeration efficiency of the refrigerator.

[0086] Then, how to prevent excessive frosting at the bottom of the evaporator during the refrigeration process, that is, to make the frosting on the evaporator uniform to improve the refrigeration efficiency of the refrigerator, is an urgent problem to be solved.

[0087] Therefore, this application provides a refrigerator that, during refrigeration, controls the operation of the compressor and the blower corresponding to the refrigerating chamber according to the ambient humidity, so that the refrigerant flowing out of the evaporator corresponding to the refrigerating chamber flows through the bottom of the evaporator corresponding to the freezing chamber and then flows to the evaporator corresponding to the freezing chamber. Thus, the temperature of the refrigerant can be used to relieve the frost layer at the bottom of the freezing evaporator, prevent excessive frosting at the bottom of the evaporator corresponding to the freezing chamber, make the frosting uniform, and improve the refrigeration efficiency of the refrigerator.

[0088] The technical solutions of this application will be described in detail below in conjunction with specific embodiments. These specific embodiments can be combined with each other or exist independently. For the same or similar concepts or processes, they may not be repeated in some embodiments. The embodiments of this application will be described below in conjunction with the drawings.

[0089] First, the specific structure of a refrigerator provided by the embodiments of this application will be described. Exemplarily, Figure 1 is a schematic diagram of a refrigerator provided by the embodiments of this application, Figure 2 is a schematic diagram of another refrigerator provided by the embodiments of this application, as Figure 1 andFigure 2 As shown, the refrigerator 10 includes a box body 101, a door body 102, and a storage compartment disposed within the box body 101.

[0090] In one possible implementation, as Figure 1 shown, the storage compartment includes a refrigerating chamber 11 and a freezing chamber, Figure 1 and the freezing chamber is not shown in

[0091] In one possible implementation, as Figure 2 shown, the storage compartment includes a refrigerating chamber, a freezing chamber, and a variable temperature chamber 12. Exemplarily, Figure 2 the upper compartments are the refrigerating chamber and the freezing chamber, and the lower compartment can be the variable temperature chamber 12, Figure 1 and the refrigerating chamber and the freezing chamber are not shown in

[0092] It can be understood that Figure 1 and Figure 2 this is only a schematic diagram of a refrigerator applicable to the present application, and it can also be a refrigerator with other structures. The present application does not limit this.

[0093] In one possible implementation, the refrigerator 10 further includes a refrigeration system 103 and a control component 104. Exemplarily, Figure 3 this is a schematic structural diagram of a refrigerator provided by an embodiment of the present application. As Figure 3 shown, the refrigeration system 103 includes a compressor 31, a condenser 32, a first evaporator 33, a second evaporator 34, and a first blower (not shown in the figure).

[0094] Among them, the compressor 31 is configured to provide power for the refrigeration of the refrigerator 10.

[0095] The condenser 32 is configured to dissipate heat from the refrigerant coming from the compressor 31.

[0096] The first evaporator 33 is configured to provide cooling capacity for the freezing chamber.

[0097] The second evaporator 34 is configured to provide cooling capacity for the refrigerating chamber.

[0098] The first blower is configured to allow air to enter the second evaporator 34 for heat exchange and send the air after heat release into the refrigerating chamber.

[0099] Among them, the compressor 31 is respectively connected to the condenser 32 and the first evaporator 33. A first solenoid valve ( Figure 3 not shown in

[0100] The condenser 32 is respectively communicated with the first evaporator 33 and the second evaporator 34, and a second solenoid valve ( Figure 3 not shown in the figure) is arranged between the condenser 32 and the first evaporator 33 and the second evaporator 34. The second solenoid valve is configured to control the flow direction of the refrigerant flowing out of the condenser 32 to the first evaporator 33 and / or the second evaporator 34.

[0101] The inlet of the first evaporator 33 is communicated with the outlet of the second evaporator 34 through a preset pipeline. A part of the pipeline of the preset pipeline is arranged in a zigzag manner at the bottom of the first evaporator 33, so that the refrigerant flowing out of the second evaporator 34 flows through the bottom of the first evaporator 33 to the first evaporator 33.

[0102] Exemplarily, the refrigeration system 103 and the control component 104 can be electrically connected. The control component 104 is configured to:

[0103] When it is determined to start the refrigeration mode, obtain the first humidity value of the environment where the refrigerator 10 is located.

[0104] If the first humidity value is above the preset humidity value, control the compressor 31 to start, and control the flow direction of the refrigerant flowing out of the condenser 32 to the second evaporator 34 through the second solenoid valve.

[0105] Control the first fan to run at a first speed, and the first speed is greater than the preset speed of the first fan when it is in the refrigeration mode.

[0106] Control the flow direction of the refrigerant flowing out of the condenser 32 to the first evaporator through the second solenoid valve.

[0107] Exemplarily, the control component 104 can determine whether to start the refrigeration mode according to the temperature of the storage compartment of the refrigerator and / or the ambient temperature of the environment where the refrigerator 10 is located, so as to realize refrigerating the storage compartment. The present application does not limit the judgment method for the control component 104 to start the refrigeration mode.

[0108] It should be noted that if the first humidity value is above the preset humidity value, the control component 104 can control the compressor 31 to run at its set minimum speed. Exemplarily, this speed can be 1200 rpm / min (revolutions per minute), so that the refrigerating capacity of the refrigerator is smaller at this time, and the frosting amount of the evaporator can be reduced.

[0109] The preset speed of the first fan when it is in the refrigeration mode can be understood as the speed of the first fan of the refrigerator in the conventional refrigeration mode. The conventional refrigeration mode is the speed of the first fan when the refrigerator 10 enters the refrigeration mode when the humidity value of the environment where the refrigerator 10 is located is less than the preset humidity value, that is, when the humidity value of the environment where the refrigerator 10 is located is relatively low.

[0110] That is to say, when the environmental humidity is relatively low and refrigeration of the refrigerating chamber is required, the first blower can be controlled to operate at a preset speed to achieve refrigeration of the refrigerating chamber. The preset speed can be set according to the environmental temperature and / or the temperature of the refrigerating chamber.

[0111] In this embodiment, during refrigeration, when the refrigerant flowing from the second evaporator 34 into the first evaporator 33 passes through the bottom of the first evaporator 33, it alleviates the frost layer condensed at the bottom of the first evaporator 33 during the refrigeration of the freezer compartment, preventing excessive frosting at the bottom of the first evaporator 33.

[0112] In a possible implementation manner, the refrigerator 10 further includes a second blower (not shown in the figure). The second blower is configured to allow air to enter the first evaporator 33 for heat exchange and send the air after heat release into the freezer compartment when refrigerating the freezer compartment. That is to say, after the refrigerant flowing out from the condenser 32 enters the first evaporator 33, the second blower can operate to allow air to enter the first evaporator 33 for heat exchange and send the air after heat release into the freezer compartment.

[0113] In a possible implementation manner, Figure 4 is a schematic structural diagram of another refrigerator provided by an embodiment of the present application. As Figure 4 shown, the refrigerator 10 may further include a humidity sensor 105. The humidity sensor 105 can be disposed outside the cabinet 101 and is in direct contact with the environment where the refrigerator 10 is located. The humidity sensor 105 is electrically connected to the control component 104.

[0114] The control component 104 can obtain the humidity value of the environment where the refrigerator is located through the humidity sensor 105. Specifically:

[0115] In a possible implementation manner, when the control component 104 determines to start the refrigeration mode, it can send a corresponding signal to the humidity sensor 105, so that the humidity sensor 105 can send a first humidity value to the control component 104 according to this signal.

[0116] In another possible implementation manner, the humidity sensor 105 can detect the humidity value of the environment where the refrigerator 10 is located at time intervals, and then send the detected humidity value to the control component 104. The control component 104 can store the received humidity value. When determining to start the refrigeration mode, the control component 104 can obtain the humidity value at the moment closest to the current moment among the stored humidity values as the first humidity value.

[0117] In a possible implementation manner, Figure 5 is a schematic structural diagram of yet another refrigerator provided by an embodiment of the present application. As Figure 5As shown, the refrigeration system 103 may further include a third evaporator 35. The inlet of the third evaporator 35 is connected to the second solenoid valve through a fifth pipeline (refer to Figure 6 ), so that when the variable temperature chamber is refrigerated, the refrigerant flowing out of the condenser 32 is controlled by the second solenoid valve to flow to the third evaporator 35. The third evaporator 35 is configured to provide cooling capacity for the variable temperature chamber. The outlet of the third evaporator 35 is connected to the inlet of the first evaporator 33, so that when the variable temperature chamber is refrigerated, the refrigerant flowing out of the third evaporator 35 flows through the first evaporator 33 and then to the compressor 31.

[0118] In a possible implementation manner, the first solenoid valve is a four-way reversing valve, including an exhaust port, an intake port, a first outlet, and a second outlet.

[0119] Figure 6 The structural schematic diagram of a refrigeration system 103 provided by an embodiment of the present application is as shown in Figure 6 As shown, the condenser 32 is connected to the first outlet of the first solenoid valve 36 through a first pipeline, and the first evaporator 33 is connected to the second outlet of the first solenoid valve 36 through a second pipeline.

[0120] The exhaust port of the first solenoid valve 36 is connected to the inlet of the compressor 31, and the intake port of the first solenoid valve 36 is connected to the outlet of the compressor 31.

[0121] When the refrigeration system 103 is in the refrigeration mode, the refrigerant flowing out of the compressor 31 enters the condenser 32 through the exhaust port and the first outlet of the first solenoid valve 36. Specifically, the flow direction of the refrigerant can be referred to Figure 6 , and the refrigerant flowing out of the first evaporator 33 flows through the second outlet to the intake port, and then enters the compressor 31.

[0122] When the refrigeration system 103 is in the defrosting mode, the refrigerant flowing out of the compressor 31 enters the first evaporator 33 through the exhaust port and the second outlet of the first solenoid valve 36. Specifically, the flow direction of the refrigerant can be referred to Figure 7 , and the refrigerant flowing out of the condenser 32 flows through the first outlet to the intake port, and then enters the compressor 31.

[0123] Among them, the second evaporator 34 is connected to the second solenoid valve 37 through a third pipeline, and the first evaporator 33 is connected to the second solenoid valve 37 through a fourth pipeline. Among them, capillary tubes are respectively arranged on the third pipeline and the fourth pipeline, specifically, a refrigerating capillary tube and a freezing capillary tube, and throttling and pressure reduction can be achieved through the capillary tubes.

[0124] Specifically, in Figure 6 Figure 6Schematic diagram of the refrigerant flow in the refrigerator in the refrigeration mode. The refrigerant at low temperature and low pressure is sucked into the compressor 31, compressed into a refrigerant at high temperature and high pressure in the cylinder of the compressor 31, and then discharged into the condenser 32. The refrigerant gas at high temperature and high pressure dissipates heat through the condenser 32, and the temperature continuously drops, gradually being cooled into a saturated vapor at normal temperature and high pressure. Then, it enters the refrigerating capillary through the first electromagnetic valve 36 for throttling and pressure reduction to become a wet vapor at normal temperature and low pressure. Subsequently, it starts to absorb heat and vaporize in the second evaporator 34, not only reducing the temperature of the second evaporator 34 and its surrounding area, but also turning the refrigerant into a gas at low temperature and low pressure. During the operation of the second evaporator 34, after the first blower is turned on and operates at the first rotation speed, the saturated vapor at normal temperature and high pressure from the condenser 32 enters the freezing capillary through the first electromagnetic valve 36 for throttling and pressure reduction to become a wet vapor at normal temperature and low pressure, and then enters the first evaporator 33. Since the pipeline of the second evaporator 34 is arranged at the bottom of the first evaporator 33, the temperature at the bottom is relatively high, and the moisture in the air from the freezer compartment is not easily condensed into frost. When passing through the first evaporator 33 for cooling, it quickly reaches the upper part of the first evaporator 33 for condensation into ice frost. Since the air humidity is relatively high at this time, the frosting on the surface of the first evaporator 33 can be made uniform.

[0125] It can be understood that in the refrigeration mode, if there is also a refrigeration requirement in the variable temperature compartment, the saturated vapor at normal temperature and high pressure from the condenser 32 enters the variable temperature capillary through the first electromagnetic valve 36 for throttling and pressure reduction to become a wet vapor at normal temperature and low pressure, and then enters the third evaporator 35. Subsequently, the refrigerant flowing out of the third evaporator 35 enters the first evaporator 33 along the pipeline.

[0126] In a possible implementation manner, the first electromagnetic valve 36 is further configured to control the flow direction of the refrigerant flowing out of the compressor 31 to the first evaporator 33 in the defrosting mode. The control component 104 is configured as follows:

[0127] When it is determined to start the defrosting mode, through the first electromagnetic valve 36, control the flow direction of the refrigerant flowing out of the compressor 31 to the first evaporator 33, so that the refrigerant flowing out of the compressor 31 passes through the first evaporator 33 and flows to the second evaporator 34.

[0128] Through the second electromagnetic valve 37, control the flow direction of the refrigerant flowing out of the second evaporator 34 to the condenser.

[0129] Specifically, reference can be made to Figure 7 In Figure 7 Figure 7It is a schematic diagram of the refrigerant flow direction in the defrosting mode of the refrigerator. The low-temperature and low-pressure refrigerant is sucked into the compressor 31, compressed into a high-temperature and high-pressure refrigerant in the cylinder of the compressor 31, and then discharged to the first evaporator 33 for defrosting the first evaporator 33. Then it enters the second evaporator 34 along the pipeline, and finally enters the condenser 32 for evaporation along the refrigerating capillary tube, and then returns to the compressor 31. It can be understood that when defrosting, the control component 104 can control the refrigerating capillary tube and the variable-temperature capillary tube to be not conducted through the first solenoid valve 36.

[0130] It should be noted that in the conventional refrigeration mode, that is, in the refrigeration mode of the refrigerator when the first humidity value is not above the preset humidity value, if it is necessary to refrigerate the refrigerating chamber and the freezing chamber at the same time, the control component 104 can control the first solenoid valve 36 to open the refrigerating capillary tube, so that after the refrigerant flows out of the condenser 32, it enters the first evaporator 33 after passing through the second evaporator 34, and the refrigeration of the refrigerating chamber and the freezing chamber can be achieved simultaneously. Or, the control component 104 can open the refrigerating capillary tube and the freezing capillary tube at the same time to achieve the refrigeration of the refrigerating chamber and the freezing chamber at the same time. If it is necessary to refrigerate the freezing chamber alone, the control component 104 can control the first solenoid valve 36 to open the freezing capillary tube to achieve the separate refrigeration of the freezing chamber. The situation of refrigerating the variable-temperature chamber and the freezing chamber at the same time is similar to the above and will not be elaborated here.

[0131] Based on the above refrigerator, Figure 8 It is a schematic flow chart of a control method for a refrigerator provided by an embodiment of the present application. This method can be executed by the control component 104 of the above refrigerator, as Figure 8 shown, this method includes the following steps.

[0132] S801. When it is determined to start the refrigeration mode, obtain the first humidity value of the environment where the refrigerator is located.

[0133] S802. Judge whether the first humidity value is above the preset humidity value.

[0134] If it is, execute S803; if not, the refrigerator enters the conventional refrigeration mode, which can refer to the above embodiment and will not be elaborated here.

[0135] S803. Control the compressor to start, and control the refrigerant flowing out of the condenser to flow to the second evaporator through the second solenoid valve.

[0136] Exemplarily, the control component can control the second solenoid valve to open the second outlet and close the first outlet to realize the flow of the refrigerant flowing out of the condenser to the second evaporator. It should be understood that closing the first outlet means closing the outlet of the compressor 31 flowing to the condenser 32, and the refrigerant flowing out of the condenser 32 can enter the intake port through the first outlet and then enter the compressor 31.

[0137] S804. Control the first blower to operate at a first speed.

[0138] Wherein, the first speed is greater than the preset speed when the first blower is in the conventional refrigeration mode. Exemplarily, the first speed can be 1500 rpm / min, and the preset speed can be 1200 rpm / min or 1000 rpm / min, etc. At the first speed, the heat exchange efficiency of the second evaporator is relatively high, such that the temperature of the refrigerant flowing into the first evaporator from the second evaporator is relatively high.

[0139] S805. Control the refrigerant flowing out from the condenser to flow to the first evaporator through the second solenoid valve.

[0140] For the specific implementation of the above steps, reference may be made to the above embodiments, which will not be elaborated herein.

[0141] In this embodiment, when it is determined to start the refrigeration mode, obtain the first humidity value of the environment where the refrigerator is located. If the first humidity value is greater than the preset humidity value, the compressor can be controlled to start, and the refrigerant flowing out from the condenser is controlled to flow to the second evaporator through the second solenoid valve. Then control the first blower to operate at the first speed, and control the refrigerant flowing out from the condenser to flow to the first evaporator through the second solenoid valve. In this application, when the refrigerant flowing into the first evaporator from the second evaporator passes through the bottom of the first evaporator, it alleviates the frost layer condensed at the bottom of the first evaporator during the refrigeration of the freezer compartment, preventing excessive frosting at the bottom of the first evaporator.

[0142] After the refrigerant flowing out from the condenser flows to the first evaporator, the rotation speed of the second blower corresponding to the freezer compartment can be further controlled, so that frost can be quickly condensed on the upper part of the first evaporator.

[0143] Specifically, Figure 9 is a schematic flowchart of another control method for a refrigerator provided in an embodiment of the present application. This method can be executed by the control component 104 of the above refrigerator, as Figure 9 shown. This method includes the following steps.

[0144] S901. When it is determined to start the refrigeration mode, obtain the first humidity value of the environment where the refrigerator is located.

[0145] S902. Determine whether the first humidity value is above the preset humidity value.

[0146] If so, execute S903; if not, the refrigerator enters the conventional refrigeration mode. Reference may be made to the above embodiments, which will not be elaborated herein.

[0147] S903. Control the compressor to start, and control the refrigerant flowing out from the condenser to flow to the second evaporator through the second solenoid valve.

[0148] S904. Control the first fan to operate at the first speed.

[0149] S905. Control the refrigerant flowing out of the condenser to flow to the first evaporator through the second solenoid valve.

[0150] S906. Control the second fan to operate at the first speed.

[0151] In this embodiment, after the fan in the refrigerating chamber is controlled to be turned on, since there is a refrigerating evaporator pipeline at the bottom of the freezing evaporator, the bottom temperature is relatively high. At this time, control the speed of the freezing fan to operate at the first speed, so that when the air passes through the freezing evaporator for cooling, it can quickly reach the upper part of the freezing evaporator to condense into frost, thereby realizing uniform frosting.

[0152] After the first preset duration of this refrigeration is completed, the speed of the first fan in the current refrigeration can be further controlled according to the current ambient humidity value to realize uniform control of frosting of the first evaporator. Exemplarily, the first preset duration can be 6 hours, or it can be other durations, and this application does not limit this.

[0153] Specifically, Figure 10 is a schematic flowchart of another control method of the refrigerator provided by the embodiment of the present application. This method can be executed by the control component 104 of the above refrigerator, as Figure 10 shown, this method includes the following steps.

[0154] S1001. After the first preset duration of this refrigeration is completed, obtain the second humidity value of the environment where the refrigerator is located.

[0155] S1002. Determine whether the second humidity value is above the preset humidity value.

[0156] If so, execute S1003; if not, the refrigerator enters the conventional refrigeration mode, which can refer to the above embodiment and will not be elaborated here.

[0157] S1003. Control the first fan to operate at the second speed.

[0158] Wherein, the second speed is less than the first speed.

[0159] That is to say, when the refrigerator is in an environment with high humidity for the first preset duration, when it is determined to start the refrigeration mode, the speed of the first fan can be controlled to be lower than the speed before the first preset duration.

[0160] Specifically, for the refrigerant flow direction of the current refrigeration and the control of the second fan, reference can be made to the above embodiment and will not be elaborated here.

[0161] In this embodiment, after the refrigerator is in a high-humidity environment for a certain period of time, the frost accumulation amount on the first evaporator gradually increases. The rotation speed of the first blower can be reduced, so that the temperature of the pipeline at the bottom of the first evaporator decreases, thereby enabling frost to form in the middle of the first evaporator.

[0162] After the rotation speed of the first blower is adjusted to the second rotation speed for a first preset period of time, if the humidity value of the environment where the refrigerator is located is still less than the preset humidity value, that is, after the refrigerator is in a relatively high-humidity environment for a certain period of time, the rotation speed of the first blower can be reduced again to accelerate the frost formation at the bottom of the first evaporator, making the frost on the entire surface of the first evaporator more uniform.

[0163] Specifically, Figure 11 is a schematic flowchart of another control method for a refrigerator provided by an embodiment of the present application. This method can be executed by the control component 104 of the above-mentioned refrigerator, as Figure 11 shown. This method includes the following steps.

[0164] S1101. After the rotation speed of the first blower is adjusted to the second rotation speed for a first preset period of time, obtain the third humidity value of the environment where the refrigerator is located.

[0165] S1102. Determine whether the third humidity value is above the preset humidity value.

[0166] If so, execute S1103; if not, the refrigerator enters the conventional refrigeration mode, which can refer to the above embodiment and will not be elaborated here.

[0167] S1103. Control the first blower to operate at the third rotation speed.

[0168] Among them, the third rotation speed is less than the second rotation speed.

[0169] That is to say, when the refrigerator is in a relatively high-humidity environment for a certain period of time and it is determined to start the refrigeration mode, the rotation speed of the first blower can be controlled to be reduced to the third rotation speed again.

[0170] Specifically, for the refrigeration in which the first blower operates at the third rotation speed, the refrigerant flow direction and the control of the second blower can refer to the above embodiment and will not be elaborated here.

[0171] In this embodiment, after the refrigerator is in a high-humidity environment for a certain period of time, the rotation speed of the first blower can be reduced again, so that the temperature of the pipeline at the bottom of the first evaporator is further reduced, enabling the moist air at the bottom of the first evaporator to quickly form frost and condense at the bottom of the evaporator, further making the frost layer condensed on the surface of the first evaporator uniform.
