[0019] If so, obtaining the interval between the current time and the last defrost time of the ice-making evaporator;

[0042] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0043] See also Figure 1 The present invention provides a refrigeration appliance 100, which may be a refrigerator. Refrigeration appliance 100 may include a housing 110, which may include a storage compartment. The storage compartment may include a freezer compartment 112. Alternatively, the storage compartment may include a refrigerator compartment 111 and a temperature-changing chamber. Refrigeration appliance 100 may include a door 120 for opening and closing the storage compartment. An independent ice-making chamber 113 may be provided within housing 110 or on door 120. Ice-making chamber 113 may have insulated compartment walls and a compartment door.

[0044] An ice maker can be installed in the ice making chamber 113, and water can be automatically supplied to the ice maker through an external water source. An ice storage box can also be installed in the ice making chamber 113, and the ice storage box is used to store the ice cubes made by the ice maker.

[0045] The refrigeration appliance 100 may further include an ice-making evaporator chamber, which may be in cold air communication with the ice-making chamber 113. The ice-making evaporator chamber may be disposed at any location within the refrigeration appliance 100, such as within the refrigerator compartment 111, the freezer compartment 112, or the ice-making chamber 113, and may be in cold air communication with the ice-making chamber 113 via a cold air duct.

[0046] The refrigeration appliance 100 further includes a refrigeration system. The refrigeration system may include a compressor 210 and an ice-making evaporator 251. The refrigeration appliance 100 may have a compressor compartment, the compressor 210 may be installed in the compressor compartment, and the ice-making evaporator 251 is disposed in an ice-making evaporator compartment.

[0047] See also Figure 2 One embodiment of the present invention provides a defrost control method that can be used in the refrigeration appliance 100 of the above embodiment. The defrost control method includes the following steps:

[0048] Check whether the ice maker has reached the preset de-icing conditions;

[0049] If yes, then get the actual ice making time of the ice maker;

[0050] If the actual ice-making time is longer than the preset time, the ice-making evaporator 251 is controlled to defrost.

[0051] In this embodiment, an ice making temperature sensor may be installed at the bottom of the ice making tray of the ice maker to detect the temperature of the ice making tray.

[0052] “Detecting whether the ice machine has reached the preset de-icing condition” may include:

[0053] Check whether the temperature of the ice tray is lower than the preset value.

[0054] For example, when the temperature of the ice tray is less than -8°C, it can be determined that the water in the ice tray has been completely frozen into ice. At this time, the ice maker has preset defrosting conditions and can be controlled to defrost.

[0055] When the ice maker reaches the preset defrosting condition, the actual ice making time of the ice maker during this ice making process can be determined. The actual ice making time can be the time elapsed from the completion of water injection into the ice maker until the ice maker reaches the preset defrosting condition. If the actual ice making time is too long, it can be determined that the cooling capacity of the ice making chamber 113 is insufficient and the refrigeration capacity of the ice making evaporator 251 has decreased. Therefore, the ice making evaporator 251 can be controlled to defrost to increase the refrigeration capacity of the ice making evaporator 251.

[0056] An ice-making and defrosting heating wire may be installed on the ice-making evaporator 251 . Controlling the defrosting of the ice-making evaporator 251 may be to control the ice-making and defrosting heating wire to be turned on, and the compressor no longer supplies refrigerant to the ice-making evaporator 251 .

[0057] In this way, whether the ice-making evaporator 251 needs to be defrosted can be accurately determined only by the actual ice-making time of the ice-making machine, so that the refrigeration capacity of the ice-making evaporator 251 can continue to meet the refrigeration demand of the ice-making chamber 113.

[0058] Furthermore, in one embodiment of the present invention, the defrost control method further includes:

[0059] Detect whether the freezing evaporator 241 has reached the defrosting condition;

[0060] If so, the freezing evaporator 241 and the ice-making evaporator 251 are controlled to defrost;

[0061] The refrigerant flows through the ice-making evaporator 251 and then enters the freezing evaporator 241 .

[0062] In this embodiment, the refrigeration appliance 100 may further include a freezer evaporator chamber. The refrigeration system of the refrigeration appliance 100 may further include a freezer evaporator 241, which may be installed in the freezer evaporator chamber. A freezer defrost heating wire may be installed on the freezer evaporator 241. Controlling defrosting of the freezer evaporator 241 may include turning on the freezer defrost heating wire, and the compressor no longer supplies refrigerant to the freezer evaporator 241.

[0063] In this embodiment, part of the refrigerant from the compressor 210 flows through the ice-making evaporator and then flows into the freezing evaporator 241 , and part of the refrigerant flows directly through the freezing evaporator 241 .

[0064] Specifically, the refrigerant flowing out of the compressor 210 passes through the condenser and is split through a one-inlet and multiple-outlet solenoid valve. A part of it directly enters the freezing evaporator 241 through the freezing capillary tube and then flows back to the compressor 210. A part of it passes through the ice-making capillary tube and the ice-making evaporator 251 and then flows through the freezing evaporator 241 and returns to the compressor 210.

[0065] See also Figure 3 In one embodiment of the present invention, the refrigeration system further includes a condenser and a filter drier. The refrigeration system may also include a refrigeration evaporator 231 for providing cold air to the refrigeration compartment 111, and a temperature-variable evaporator for providing cold air to the temperature-variable compartment. The refrigerant flowing out of the compressor 210 is split by a one-inlet, three-outlet solenoid valve. One path flows directly through the freezing capillary tube to the freezing evaporator 241, while another path flows directly through the temperature-variable capillary tube to the temperature-variable evaporator. The other path is further split by a one-inlet, two-outlet solenoid valve into two paths, one through the ice-making capillary tube to the ice-making evaporator 251, and the other through the refrigeration capillary tube to the refrigeration evaporator 231. After passing through the ice-making evaporator 251, the refrigeration evaporator 231, and the temperature-variable evaporator, the refrigerant flows to the freezing evaporator 241 and then returns to the compressor 210 through the freezing evaporator 241.

[0066] Of course, if the refrigeration appliance 100 does not have a refrigeration chamber 111 or a variable temperature chamber, it does not have a corresponding evaporator. Alternatively, the refrigeration chamber 111 and the variable temperature chamber can also be cooled by other refrigeration systems, that is, the evaporator in the refrigeration system can only include an ice-making evaporator 251 and a freezing evaporator 241.

[0067] In this embodiment, whether the freezing evaporator 241 needs to be defrosted can be determined by the cumulative door opening time of the freezing chamber 112. When the cumulative door opening time of the freezing chamber 112 is greater than the preset time, the freezing evaporator 241 can be controlled to start defrosting.

[0068] Since the refrigerant flows through the ice-making evaporator 251 and then enters the freezing evaporator 241, when the freezing evaporator 241 needs to defrost, the ice-making evaporator 251 needs to stop refrigerating, causing the temperature of the ice-making chamber 113 to fluctuate. At the same time, since the temperature of the ice-making chamber 113 also fluctuates when the ice-making evaporator 251 defrosts, the impact on the temperature of the ice-making chamber 113 can be reduced by controlling the ice-making evaporator 251 to defrost synchronously with the freezing evaporator 241.

[0069] Furthermore, in this embodiment, the defrost control method further includes:

[0070] If it is detected that the freezing evaporator 241 reaches the defrosting condition, the interval between the current time and the last defrosting time of the ice-making evaporator 251 is obtained;

[0071] If the interval time is longer than the preset interval time, the ice-making evaporator 251 is controlled to stop defrosting when it is detected that the temperature of the ice-making evaporator 251 is higher than the first preset temperature;

[0072] If the interval time is less than the preset interval time, the ice-making evaporator 251 is controlled to stop defrosting when it is detected that the temperature of the ice-making evaporator 251 is greater than the second preset temperature;

[0073] Wherein, the first preset temperature is greater than the second preset temperature.

[0074] In this embodiment, the preset interval time can be about 12 hours. An ice making and defrosting temperature sensor can be installed in the ice making evaporator chamber to detect the temperature of the ice making evaporator 251. A freezing and defrosting temperature sensor can be installed in the freezing evaporator chamber to detect the temperature of the freezing evaporator 241.

[0075] When the evaporator is defrosting, the defrost heating wire corresponding to the evaporator is turned on, and the temperature in the evaporator chamber rises. Therefore, it is possible to determine whether the defrost is completed through the defrost temperature sensor in the evaporator chamber.

[0076] When it is detected that the temperature of the freezing evaporator 241 is greater than a preset temperature, the freezing evaporator 241 may be controlled to stop defrosting.

[0077] When the freezing evaporator 241 reaches the defrosting condition and the ice-making evaporator 251 subsequently defrosts, if the interval between the last defrosting of the ice-making evaporator 251 and the last defrosting is long, it can be determined that the ice-making evaporator 251 has a lot of frost, and the ice-making evaporator 251 can operate according to normal defrosting conditions, that is, when it is detected that the temperature of the ice-making evaporator 251 is high, such as 7°C, the ice-making evaporator 251 is controlled to stop defrosting, so that the ice-making evaporator 251 can defrost more thoroughly.

[0078] If the time interval between the last defrost of the ice-making evaporator 251 and the last defrost of the ice-making evaporator 251 is short, the refrigeration capacity of the ice-making evaporator 251 may be good, and there may be less frost on the surface of the ice-making evaporator 251. If the temperature of the ice-making evaporator 251 is detected to be lower than the normal defrost stop temperature, the ice-making evaporator 251 may be controlled to stop defrosting. For example, if the temperature of the ice-making evaporator 251 is detected to be 3°C, the defrost may be controlled to stop. In this way, the impact of the rising temperature of the ice-making evaporator room on the temperature of the ice-making chamber 113 during the defrost process can be reduced, thereby reducing the risk of ice cubes stored in the ice storage box in the ice-making chamber 113 melting and sticking due to the temperature increase can be reduced.

[0079] Furthermore, in another embodiment of the present invention, the defrost control method further includes:

[0080] Detect whether the freezing evaporator 241 has reached the defrosting condition;

[0081] If yes, then obtain the interval between the current time and the last defrosting time of the ice-making evaporator 251;

[0082] If the interval time is less than the preset interval time, only the freezing evaporator 241 is controlled to defrost;

[0083] If the interval time is longer than the preset interval time, the freezing evaporator 241 and the ice-making evaporator 251 are controlled to defrost;

[0084] The refrigerant flows through the ice-making evaporator 251 and then enters the freezing evaporator 241 .

[0085] The difference between this embodiment and the previous embodiment is that when the freezing evaporator 241 needs to be defrosted, if it is detected that the interval between the last defrost of the ice-making evaporator 251 and the last defrost is short, only the freezing evaporator 241 is controlled to defrost, while the ice-making evaporator 251 is not controlled to defrost. In this case, the cooling capacity of the ice-making evaporator 251 is relatively good, and not defrosting the ice-making evaporator 251 can effectively prevent the temperature of the ice-making chamber 113 from being affected by frequent defrosting of the ice-making evaporator 251.

[0086] Furthermore, in one embodiment of the present invention, the defrost control method further includes:

[0087] Detecting whether the refrigeration evaporator 231 and / or the variable temperature evaporator has reached the defrosting condition;

[0088] If yes, control the refrigeration evaporator 231 and / or the temperature-variable evaporator, and the ice-making evaporator 251 to defrost;

[0089] The refrigeration evaporator 231 and / or the temperature-variable evaporator and the ice-making evaporator 251 share a compressor 210 .

[0090] In this embodiment, if Figure 3 As shown, the refrigeration evaporator 231 and the variable temperature evaporator can be connected in parallel with the ice-making evaporator 251, and they can share a compressor 210. When the refrigeration evaporator 231 and the variable temperature evaporator are defrosting, the ice-making evaporator 251 can be controlled to defrost synchronously to reduce the impact on the temperature of the ice-making chamber 113.

[0091] Furthermore, in one embodiment of the present invention, the defrost control method further includes:

[0092] When the ice making evaporator 251 is defrosting, the temperature of the ice making tray of the ice making machine is detected;

[0093] If the temperature of the ice tray is greater than a preset value, the ice-making evaporator 251 is controlled to stop defrosting.

[0094] In this embodiment, when ice evaporator 251 is defrosting, the temperature of ice chamber 113 will rise. Specifically, in this embodiment, ice evaporator 251 can be located inside ice chamber 113, and the air vent of the ice evaporator chamber can be opposite and close to the ice maker. During the defrosting process of ice evaporator 251, the temperature inside the ice evaporator chamber rises, and the high-temperature gas inside the ice evaporator chamber can be directly discharged to the bottom of the ice maker through the air vent. Therefore, if the temperature of the ice tray is detected to be high, ice evaporator 251 can be controlled to stop defrosting, reducing the impact of ice evaporator 251 defrosting on the temperature of ice chamber 113 and preventing the ice in the ice storage box from melting and sticking.

[0095] Furthermore, in this embodiment, the defrost control method further includes:

[0096] If the temperature of the ice-making evaporator 251 is lower than the first preset temperature when the ice-making evaporator 251 stops defrosting, the ice-making evaporator 251 is controlled to start defrosting after a preset time.

[0097] In this embodiment, the first preset temperature can be the temperature at which the ice-making evaporator 251 stops defrosting normally. The first preset temperature can be about 7°C. However, if the ice-making evaporator 251 stops defrosting due to the high temperature of the ice tray during the defrosting process, the frost on the surface of the ice-making evaporator 251 has not completely melted at this time. Therefore, in order to ensure the cooling capacity of the ice-making evaporator 251, the defrosting can be restarted after a preset time, such as after 12 hours.

[0098] In this way, the excessive temperature in the ice making chamber 113 caused by the defrosting of the ice making evaporator 251 and the adhesion of ice cubes in the ice storage box can be reduced.

[0099] See also Figure 4 One embodiment of the present invention further provides a refrigeration appliance 100, comprising a memory 202 and a processor 201, wherein the memory 202 and the processor 201 are communicatively connected via a communication bus 204. The memory 202 stores a computer program executable by the processor 201, and when the processor 201 executes the computer program, the steps of the defrost control method described in the above embodiment are implemented. The refrigeration appliance 100 also includes a communication interface 203 connected to the communication bus 204 for communicating with other devices within the refrigeration appliance 100.

[0100] An embodiment of the present invention further provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the defrost control method in the above embodiment are implemented.

[0101] To sum up, the defrost control method provided by the present invention determines whether to defrost the ice-making evaporator 251 based on the actual ice-making time of the ice-making machine. When the actual ice-making time is longer than the preset time, it is determined that the refrigeration capacity of the ice-making evaporator 251 has decreased, and it is defrosted. The overall control is simple.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
