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 for 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. In order to improve the refrigeration efficiency of the refrigerator, it is necessary to defrost the evaporator. During the defrosting process, heat convects upward in a cycle, and as the ice and frost melt, the gravity causes them to move downward and fall to the bottom of the evaporator, resulting in incomplete melting of the ice and frost at the bottom of the evaporator.

[0003] Currently, a heating wire can be arranged at the bottom of the evaporator to melt the ice at the bottom of the evaporator through the heat of the heating wire. However, defrosting using the heating wire results in relatively high power consumption of the refrigerator. Summary of the Invention

Among them, the fan assembly includes a first fan. The control component is configured to, when determining to start the defrosting mode, start the first fan, determine that the rotation speed of the first fan is a first rotation speed, and then control the first fan to operate at the first rotation speed. Since heat convects and circulates upward, by blowing air downward from above the evaporator through the first fan, forced heat convection is achieved, and the frost that has fallen to the bottom of the evaporator can be melted with relatively low power consumption.

[0031] In some embodiments of the present application, a first air duct and a second air duct are formed in the second chamber; the outlet of the first air duct is the air outlet, the inlet of the first air duct is the outlet of the second air duct, and the inlet of the second air duct is the air return opening;

[0032] The evaporator is located in the second air duct;

[0033] The fan assembly further includes a position adjusting device, the first end of the position adjusting device is fixedly arranged on the first partition board, and the second end of the position adjusting device is fixedly connected with the first fan;

[0034] The position adjusting device is configured to:

[0035] When the position adjusting device is in a contracted state, control the first fan to be located in the first air duct;

[0036] When the position adjusting device is in an extended state, control the first fan to be located in the second air duct.

[0037] In this embodiment, the first fan can be controlled to be located in the first air duct or the second air duct through the position adjusting device, so as to control the air direction in the second chamber during refrigeration or defrosting.

[0039] When it is determined to turn on the refrigeration mode, control the position adjustment device to be in the contracted state;

[0040] When it is determined to turn on the defrosting mode, control the position adjustment device to be in the extended state.

[0041] In this embodiment, in the refrigeration mode, the first blower can be controlled to be located in the first air duct to realize the refrigeration cycle between the second chamber and the first chamber. In the defrosting mode, the first blower is controlled to be located in the second air duct to realize the heat convection of the evaporator to achieve uniform defrosting.

[0083] To make the objectives, implementation manners and advantages of this application clearer, the following will clearly and completely describe the exemplary implementation manners of this application with reference to the accompanying drawings in the exemplary embodiments of this application. Apparently, the described exemplary embodiments are only a part rather than all of the embodiments of this application.

[0084] It should be noted that the brief description of terms in this application is only for facilitating the understanding of the subsequent described implementation manners, rather than intending to limit the implementation manners of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0085] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusively include. For example, a product or device including 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.

[0086] When the refrigerator is refrigerating, the moisture in the circulating air will frost on the evaporator and the connecting pipeline. To improve the refrigeration efficiency of the refrigerator, it is necessary to defrost the evaporator.

[0087] Exemplarily, defrosting can be carried out by the way of countercurrent defrosting, that is, the refrigerant flows countercurrently in each mechanism in the refrigeration system, and the high-temperature and high-pressure gas flowing out of the compressor enters the evaporator, and the heat from the high-temperature and high-pressure gas is utilized to realize defrosting for the evaporator.

[0088] However, during the defrosting process, the heat convects upward in a cycle, and as the ice frost melts, the gravity will cause it to move downward and fall to the bottom of the evaporator, resulting in the problem that the ice frost at the bottom of the evaporator cannot be completely melted.

[0089] Currently, a heating wire can be arranged at the bottom of the evaporator to melt the ice at the bottom of the evaporator through the heat of the heating wire. However, using the heating wire for defrosting results in a relatively high power consumption of the refrigerator.

[0090] Therefore, this application provides a refrigerator, with a blower arranged above the evaporator, so that during countercurrent defrosting, the blower blows air downward from above the evaporator to realize forced convection of heat, and the ice frost that has fallen to the bottom of the evaporator can be melted.

[0091] The following will detail the technical solutions of this application with reference to specific embodiments. These several specific embodiments below 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 following will describe the embodiments of this application with reference to the accompanying drawings.

[0092] Figure 1 Schematic diagram of a refrigerator provided by an embodiment of the present application. As Figure 1 shown, the refrigerator 10 includes a box body 101, a door body 102, and a storage compartment provided in the box body 101.

[0093] In a possible implementation, as Figure 1 shown, the storage compartment includes a refrigerating compartment and a freezing compartment 11, Figure 1 and the refrigerating compartment is not shown.

[0094] It can be understood that Figure 1 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.

[0095] In a possible implementation, the refrigerator 10 further includes a refrigeration system 103 and a control component 104. Exemplarily, Figure 2 schematic diagram of the structure of a refrigerator provided by an embodiment of the present application. As Figure 2 shown, the refrigeration system 103 includes a compressor 31, a condenser 32, and an evaporator 33.

[0096] Among them, the compressor 31 is configured to provide power for the refrigeration of the refrigerator 10.

[0097] The condenser 32 is configured to dissipate heat from the refrigerant coming from the compressor 31.

[0098] The evaporator 33 is configured to provide cooling capacity for the storage compartment.

[0099] Among them, the compressor 31 is respectively communicated with the condenser 32 and the evaporator 33. An electromagnetic valve 34 is provided between the compressor 31 and the condenser 32 and the evaporator 33. This electromagnetic valve can control the flow direction of the refrigerant flowing out of the compressor 31. For example, in the refrigeration mode, the refrigerant flowing out of the compressor 31 flows to the condenser 32, and in the defrosting mode, the refrigerant flowing out of the compressor 31 flows to the evaporator 33.

[0100] In a possible implementation, Figure 3 schematic diagram of the structure of a refrigeration system 103 provided by an embodiment of the present application. As Figure 3 shown, the electromagnetic valve 34 includes an exhaust port, an intake port, a first outlet, and a second outlet. Among them, the first outlet is communicated with the condenser 32 through a first pipeline, the second outlet is communicated with the evaporator 33 through a second pipeline, the exhaust port of the electromagnetic valve 34 is connected to the inlet of the compressor 31, and the intake port of the electromagnetic valve 34 is connected to the outlet of the compressor 31.

[0101] The control component 104 is configured to:

[0102] When it is determined to turn on the refrigeration mode, the solenoid valve 34 is controlled to open the first outlet and close the second outlet. The refrigerant flowing out of the compressor 31 enters the condenser 32 through the exhaust port and the first outlet, then flows through the condenser 32 to the evaporator 33, and finally flows to the compressor 31 to complete the refrigeration cycle of the refrigerator. Exemplarily, Figure 4 It is a schematic diagram of the refrigerant flow direction when the refrigeration system 103 exemplified in the present application is in the refrigeration mode. It should be understood that closing the second outlet means closing the outlet from the compressor 31 to the evaporator 33, and the refrigerant flowing out of the evaporator 33 can enter the intake port through the second outlet and then enter the compressor 31.

[0103] When it is determined to turn on the defrosting mode, the solenoid valve 34 is controlled to open the second outlet and close the first outlet. The refrigerant flowing out of the compressor 31 enters the evaporator 33 through the exhaust port and the second outlet, then flows from the evaporator 33 to the condenser 32, and finally flows to the compressor 31. Among them, the evaporator 33 releases heat to melt the frost layer on the evaporator 33, achieving the purpose of defrosting. Exemplarily, Figure 4 It is a schematic diagram of the refrigerant flow direction when the refrigeration system 103 exemplified in the present application is in the defrosting mode. It should be understood that closing the first outlet means closing the outlet from the compressor 31 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.

[0104] Specifically, a capillary tube (not shown in the figure) can be provided between the condenser 32 and the evaporator 33. In Figure 4 this, 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 into the condenser 32. The high-temperature and high-pressure refrigerant gas dissipates heat through the condenser 32, and the temperature continuously drops, gradually being cooled into a normal-temperature and high-pressure saturated vapor, and then throttled and depressurized through the capillary tube to become a normal-temperature and low-pressure wet vapor. Subsequently, it starts to absorb heat and vaporize in the evaporator 33, not only reducing the temperature of the evaporator 33 and its surroundings, but also turning the refrigerant into a low-temperature and low-pressure gas, and then passing through the compressor 31 again to complete the refrigeration cycle of the refrigerator.

[0105] In Figure 5In this case, 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 to the evaporator 33. The refrigerant gas at high temperature and high pressure dissipates heat through the evaporator 33, and its temperature continuously drops, gradually being cooled into a saturated vapor at normal temperature and high pressure. Then, it undergoes throttling and pressure reduction through the capillary tube to become a wet vapor at normal temperature and low pressure. Subsequently, it starts to absorb heat and vaporize in the condenser 32, not only reducing the temperature of the condenser 32 and its surroundings, but also turning the refrigerant into a gas at low temperature and low pressure. Then, the gas at low temperature and low pressure returns to the compressor 31. Among them, the refrigerant at high temperature and high pressure can melt the frost condensed on the evaporator 33 by means of heat conduction in the evaporator 33 to achieve the purpose of defrosting.

[0106] Figure 6 The following is a schematic structural diagram of a refrigerator provided by an embodiment of the present application. As Figure 6 shown, an inner container 12 is provided inside the box body 101. The inner container 12 includes a first chamber 14 and a second chamber 15 defined by a first partition 13. The first chamber 14 is used for storing food, and the second chamber 15 is used for arranging a refrigeration system 103, that is, arranging equipment required for refrigeration, such as an evaporator 33, etc. Among them, an air outlet and an air return port are provided on the first partition 13, and the first chamber 14 and the second chamber 15 are communicated through the air outlet and the air return port.

[0107] Specifically, the evaporator 33 in the refrigeration system 103 is configured to provide cold air for the first chamber 14.

[0108] The refrigeration system 103 further includes a fan assembly 16 disposed near the air outlet, which is configured to drive the air with the cold air provided by the evaporator 33 to enter the first chamber 14 through the air outlet when the refrigeration system 103 is in the refrigeration mode, and is configured to drive the air above the evaporator 33 to flow to the bottom of the evaporator 33 when the refrigeration system 103 is in the defrosting mode.

[0109] The fan assembly 16 includes a first fan 161, and the control assembly 104 is further configured to:

[0110] When it is determined to turn on the defrosting mode, turn on the first fan 161, determine that the rotation speed of the first fan 161 is the first rotation speed, and then control the first fan 161 to operate at the first rotation speed.

[0111] It can be understood that when it is determined to turn on the defrosting mode, the first fan 161 operates at the first rotation speed. Due to the upward convection cycle of heat, the first fan 161 can drive the air above the evaporator 33 to flow to the bottom of the evaporator 33 to melt the frost layer at the bottom of the evaporator 33.

[0112] In this embodiment, the control component 104 is configured to, when determining to turn on the defrosting mode, turn on the first blower 161, determine that the rotation speed of the first blower 161 is the first rotation speed, and then control the first blower 161 to operate at the first rotation speed. Since heat convects and circulates upward, by blowing air downward from above the evaporator 33 through the first blower 161, forced heat convection is achieved, and the frost that has fallen to the bottom of the evaporator 33 can be melted with relatively low power consumption.

[0113] Figure 7 FIG. is a schematic structural diagram of a second chamber 15 provided by an embodiment of the present application, as Figure 7 shown, a first air duct and a second air duct are formed in the second chamber 15. The outlet of the first air duct is the air outlet, the inlet of the first air duct is the outlet of the second air duct, and the inlet of the second air duct is the air return port.

[0114] The evaporator 33 is located in the second air duct. The blower assembly 16 further includes a position adjusting device 162. The first end of the position adjusting device 162 is fixedly arranged on the first partition 13, and the second end of the position adjusting device 162 is fixedly connected to the first blower 161.

[0115] The position adjusting device 162 is configured to:

[0116] When the position adjusting device 162 is in a contracted state, control the first blower 161 to be located in the first air duct.

[0117] When the position adjusting device 162 is in an extended state, control the first blower 161 to be located in the second air duct.

[0118] Specifically, the position adjusting device 162 can be a spring assembly. When the position adjusting device 162 is in a contracted state, it can pull the first blower 161 into the first air duct. When the position adjusting device 162 is in an extended state, it can push the first blower 161 into the second air duct.

[0119] Exemplarily, Figure 7 FIG. is a schematic diagram of the position adjusting device 162 in a contracted state according to an example of the present application, Figure 8 FIG. is a schematic diagram of the position adjusting device 162 in an extended state according to an example of the present application.

[0120] In a possible implementation manner, the control component 104 is further configured to:

[0121] When determining to turn on the refrigeration mode, control the position adjusting device 162 to be in a contracted state. When determining to turn on the defrosting mode, control the position adjusting device 162 to be in an extended state.

[0122] By controlling the state of the position adjusting device 162, in the refrigeration mode, the first blower 161 can be controlled to be located in the first air duct, so as to realize the refrigeration cycle between the second chamber 15 and the first chamber 14. In the defrosting mode, the first blower 161 is controlled to be located in the second air duct to realize the heat convection of the evaporator, so as to realize uniform defrosting.

[0123] It can be understood that the refrigerator further includes a refrigeration blower (not shown in the figure), which is configured to allow air to enter the second chamber 15 for heat exchange and send the air after heat release into the first chamber 14, so as to refrigerate the first chamber 14. When the refrigeration system 103 is in the refrigeration mode, the refrigeration blower is in the operating state, and when the refrigeration system 103 is in the defrosting mode, the refrigeration blower is in the stopped state.

[0124] In a possible implementation manner, as Figure 7 and Figure 8 shown, the second chamber 15 is arranged between the first partition 13 and the air duct cover plate 17. A part of the first partition 13, the second partition 18 and the third partition 19 define the first air duct. One side of the second partition 18 abuts against the air duct cover plate 17, one side of the third partition 19 abuts against the air duct cover plate 17, and the other side of the second partition 18 and the other side of the third partition form the inlet of the first air duct (the outlet of the second air duct).

[0125] Another part of the first partition 13, the second partition 18, the third partition 19 and the air duct cover plate 17 define the second air duct.

[0126] In this embodiment, the first air duct and the second air duct are defined by the first partition 13, the second partition 18, the third partition 19 and the air duct cover plate 17, so as to control the flow of air in the second chamber 15 in the defrosting mode and the refrigeration mode.

[0127] In a possible implementation manner, the refrigerator may further include a temperature sensor (not shown in the figure). The temperature sensor is arranged on the surface of the evaporator 33 and is configured to detect the temperature value on the surface of the evaporator 33. This temperature value can be used to determine the rotation speed of the first blower. For details, reference can be made to the following embodiments.

[0128] Based on the above refrigerator, Figure 9 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 above control component 104. As Figure 9 shown, this method includes the following steps.

[0129] S901. When it is determined that the defrosting mode is turned on, turn on the first blower and determine that the rotation speed of the first blower is the first rotation speed.

[0130] S902. Control the first blower to operate at the first rotation speed.

[0131] Exemplarily, the control component can send an instruction to the first blower to control the first blower to operate at a first rotational speed. The present application does not limit the manner in which the control component controls the operation of the first blower.

[0132] In this embodiment, when it is determined to turn on the defrost mode, the first blower is turned on, and the rotational speed of the first blower is determined to be the first rotational speed, and then the first blower is controlled to operate at the first rotational speed. Since heat convects and circulates upward, by blowing air downward from above the evaporator through the first blower, forced heat convection is achieved, and the frost that has fallen to the bottom of the evaporator can be melted with relatively low power consumption.

[0133] Furthermore, after controlling the first blower to operate at the first rotational speed, the rotational speed of the first blower can be gradually increased to further improve the melting effect of the frost at the bottom of the evaporator.

[0134] Specifically, Figure 10 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 above-mentioned control component 104, as Figure 10 shown, this method includes the following steps.

[0135] S1001. When it is determined to turn on the defrost mode, turn on the first blower and determine the rotational speed of the first blower to be the first rotational speed.

[0136] S1002. Control the first blower to operate at the first rotational speed.
