[0041] 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.

[0042] See also Figure 1The present invention provides a refrigeration device 100, which may be a refrigerator. Refrigeration device 100 may include a housing 110, which may include a storage compartment. The storage compartment may include a freezer compartment 112. Of course, the storage compartment may also include a refrigerator compartment 111 and a temperature-changing chamber. Refrigeration device 100 may include a door 120 for opening and closing the storage compartment. Door 120 may include a freezer door for opening and closing the freezer compartment.

[0043] An ice maker and an ice storage box may be installed in the ice making chamber 113 , and water may be automatically supplied to the ice maker through an external water source.

[0044] In this embodiment, the refrigeration device 100 further includes a refrigeration system. The refrigeration system may include a compressor 210, an ice-making evaporator 251, and a freezing evaporator 241. The refrigeration device 100 may have a compressor compartment, and the compressor 210 may be installed in the compressor compartment. The refrigeration device 100 may also include an ice-making evaporator chamber and a freezing evaporator chamber, with the ice-making evaporator 251 disposed in the ice-making evaporator chamber and the freezing evaporator 241 disposed in the freezing evaporator chamber. The ice-making evaporator chamber may be in cold air communication with the ice-making chamber 113, and the freezing evaporator chamber may be in cold air communication with the freezing chamber 112.

[0045] In one embodiment of the present invention, the ice-making evaporator chamber can be set at any position in the refrigeration equipment 100, such as in the refrigerator compartment 111, the freezer compartment 112, or the ice-making compartment 113, and can be connected to the ice-making compartment 113 through a cold air pipe.

[0046] In this embodiment, part of the refrigerant from the compressor 210 flows through the refrigeration evaporator and then flows into the freezing evaporator 241 , and part of the refrigerant flows directly through the freezing evaporator 241 .

[0047] 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.

[0048] See also Figure 2In 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.

[0049] Of course, if the refrigeration equipment 100 does not have a cold storage room 111 or a variable temperature chamber, it does not have a corresponding evaporator. Alternatively, the cold storage room 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.

[0050] Since the volume of the ice making chamber 113 is smaller than that of the freezing chamber 112, the refrigeration demand in the freezing chamber 112 is generally higher. Such a setting can make full use of the cooling capacity, meet the refrigeration demand of the freezing chamber 112, and improve the refrigeration efficiency.

[0051] In this embodiment, the refrigeration device 100 further includes an ice-making temperature sensor and a freezing temperature sensor. The ice-making temperature sensor is used to detect the temperature in the ice-making chamber 113 and can be placed in the ice-making chamber 113. The freezing temperature sensor is used to detect the temperature in the freezing chamber 112 and can be placed in the freezing chamber 112.

[0052] An embodiment of the present invention provides an evaporator defrost control method, which can be used in the refrigeration device 100 of the above embodiment.

[0053] See also Figure 3 , the evaporator defrost control method includes:

[0054] When the freezing evaporator 241 corresponding to the freezing chamber 112 or the ice-making evaporator 251 corresponding to the ice-making chamber 113 is defrosting, the temperature of the ice-making chamber 113 and the temperature of the freezing chamber 112 are obtained;

[0055] Determine whether the temperature difference between the freezing chamber 112 and the ice making chamber 113 is greater than a preset value;

[0056] If so, the freezing evaporator 241 and the ice-making evaporator 251 of the ice-making chamber 113 are controlled to defrost.

[0057] In this embodiment, an ice-making and defrosting heating element may be provided in the ice-making evaporator chamber, and a freezing and defrosting heating element may be provided in the freezing and defrosting evaporator chamber. Controlling the defrosting of the ice-making evaporator 251 may be to control the heating of the ice-making and defrosting heating element, and controlling the defrosting of the freezing and defrosting evaporator 241 may be to control the heating of the freezing and defrosting heating element.

[0058] A defrost temperature sensor may be provided in the ice making evaporator chamber, and when the temperature in the ice making evaporator chamber is higher than a preset temperature, defrosting may be stopped. A defrost temperature sensor may also be provided in the freezer evaporator chamber, and when the temperature in the freezer evaporator chamber is detected to be higher than a preset temperature, defrosting may be stopped.

[0059] During the defrosting process of the freezing evaporator 241, the freezing evaporator 241 stops refrigerating, and the temperature in the freezing evaporator room rises, which may cause the temperature in the freezing chamber 112 to rise. Similarly, during the defrosting process of the ice making evaporator 251, the ice making evaporator 251 also stops refrigerating, and the temperature in the ice making evaporator room rises, which may cause the temperature in the ice making chamber 113 to rise.

[0060] In this embodiment, an insulating partition 1131 may be provided between the ice-making chamber 113 and the freezer compartment 112. In a specific embodiment, the ice-making chamber 113 may be provided within the freezer compartment 112, with the insulating partition 1131 installed within the freezer compartment 112 to separate the ice-making chamber 113. The ice-making chamber 113 and the freezer compartment 112 are cooled by the ice-making evaporator 251 and the freezing evaporator 241, respectively, and no cold air is transferred between the ice-making chamber 113 and the freezer compartment 112. If the temperature difference between the freezer compartment 112 and the ice-making chamber 113 is too large, the insulating partition 1131 may easily deform.

[0061] When the freezing evaporator 241 or the ice-making evaporator 251 is defrosted, the temperature of the corresponding compartment will rise, and the temperature difference between the freezing chamber 112 and the ice-making chamber 113 will become larger. Therefore, when the freezing evaporator 241 is defrosted, if the temperature difference between the freezing chamber 112 and the ice-making chamber 113 is greater than the preset value, the ice-making evaporator 251 and the freezing evaporator 241 can be controlled to defrost synchronously to avoid the adverse effects caused by further increase in the temperature difference between the freezing chamber 112 and the ice-making chamber 113.

[0062] Furthermore, in one embodiment of the present invention, the evaporator defrost control method further includes:

[0063] Detecting a freezer door switch signal of the freezer compartment 112;

[0064] Obtain the cumulative opening time of the freezer door after the freezer evaporator 241 is defrosted;

[0065] When the accumulated opening time is longer than the preset time, the ice-making evaporator 251 and the freezing evaporator 241 are controlled to defrost;

[0066] The ice-making chamber 113 is disposed in the freezing chamber 112 .

[0067] In this embodiment, the ice-making chamber 113 is arranged in the freezer chamber 112, and the freezer door can be used to open and close the freezer chamber 112 and the ice-making chamber 113 inside it at the same time. Of course, an independent ice-making door 1132 can also be set, but when the freezer door is closed, the freezer door covers the ice-making door 1132, that is, the freezer door must be opened first before the ice-making door 1132 can be opened.

[0068] The refrigeration device 100 may also be provided with a freezer door switch detection device, which may be a Hall sensor that can detect the open / close state of the freezer door. When the freezer door is detected to be open, the freezer door opening time can be calculated, and the cumulative opening time of the freezer door after the freezer evaporator 241 is defrosted can be obtained. When the cumulative opening time of the freezer door is greater than a preset time, it can be determined that the freezer evaporator 241 needs to be defrosted. At the same time, since the ice making chamber 113 is arranged in the freezer chamber 112, it can adopt the same defrosting judgment standard. That is, when the cumulative opening time is greater than a preset time, the ice making evaporator 251 and the freezer evaporator 241 can be controlled to defrost synchronously, thereby reducing costs and simplifying the control program.

[0069] In another embodiment provided by the present invention, the evaporator control method further includes:

[0070] Detecting a freezer door switch signal of the freezer compartment 112;

[0071] Obtaining a first cumulative opening time of the freezer door after the self-freezing evaporator 241 is defrosted, and a second cumulative opening time of the freezer door after the self-made ice evaporator 251 is defrosted;

[0072] When the first accumulated opening time is greater than the first preset time, the freezing evaporator 241 is controlled to defrost;

[0073] When the second accumulated opening time is greater than the second preset time, the ice-making evaporator 251 is controlled to defrost;

[0074] The ice-making chamber 113 is disposed in the freezing chamber 112 , and the first preset time length is shorter than the second preset time length.

[0075] Compared with the previous embodiment, both embodiments only have one freezer door switch detection device for detecting the freezer door switch state. However, in this embodiment, the ice making evaporator 251 and the freezer evaporator 241 use different defrosting judgment criteria.

[0076] In this embodiment, the ice making chamber 113 may have an independent ice making door 1132. Since the user may not necessarily open the ice making door 1132 to take ice when the freezer door is open, that is, the freezer door is opened more frequently than the ice making door 1132, the opening of the freezer door has a greater impact on the formation of frost on the freezing evaporator 241 than on the formation of frost on the ice making evaporator 251.

[0077] By separately counting the first cumulative opening time of the freezer door after the freezing evaporator 241 defrosts and the second cumulative opening time of the freezer door after the ice-making evaporator 251 defrosts, independent control of the defrosting of the ice-making evaporator 251 and the defrosting of the freezing evaporator 241 can be achieved, thereby reducing the number of defrosting times of the ice-making evaporator 251 and reducing the risk of temperature rise in the ice-making chamber 113 and melting and sticking of ice cubes in the ice storage box caused by the defrosting of the ice-making evaporator 251.

[0078] The present invention also provides another embodiment, wherein the evaporator defrost control method includes:

[0079] Detecting a freezer door switch signal of the freezer compartment 112 and an ice-making door 1132 switch signal of the ice-making compartment 113;

[0080] Obtain the cumulative opening time of the freezer door after the freezer evaporator 241 defrosts;

[0081] Obtain the cumulative opening time of the ice-making door 1132 after the homemade ice evaporator 251 is defrosted;

[0082] When the accumulated opening time of the freezing door is greater than the first preset time, the freezing evaporator 241 is controlled to defrost;

[0083] When the accumulated opening time of the ice-making door is greater than the second preset time, the ice-making evaporator 251 is controlled to defrost.

[0084] The difference between this embodiment and the previous embodiment is that, in this embodiment, an ice-making door switch detection device is additionally provided to detect the switch signal of the ice-making door 1132, and obtain the cumulative opening time of the ice-making door 1132 after the ice-making evaporator 251 is defrosted, and the defrosting of the freezing evaporator 241 and the defrosting of the ice-making evaporator 251 are controlled respectively by the cumulative opening time of the freezing door and the cumulative opening time of the ice-making door.

[0085] In the technical solution provided in this embodiment, the frost state of the ice-making evaporator 251 can be more accurately obtained through the cumulative opening time of the ice-making door 1132, so as to judge whether the ice-making evaporator 251 needs to be defrosted, reduce unnecessary defrosting of the ice-making evaporator 251, and reduce the impact of the defrosting of the ice-making evaporator 251 on the temperature of the ice-making chamber 113, thereby reducing the risk of ice melting and sticking in the ice storage box.

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

[0087] Obtaining the freezing and defrosting interval of the freezing evaporator 241 according to the ambient temperature;

[0088] When the running time of the freezing evaporator 241 after defrosting reaches the freezing and defrosting interval time, the freezing evaporator 241 is controlled to defrost.

[0089] In this embodiment, there may be multiple conditions for starting the defrosting of the freezing evaporator 241. When it is detected that any defrosting condition is met, the freezing evaporator 241 can be controlled to start defrosting, that is, the freezing defrosting heating element can be controlled to turn on. For example, the freezing evaporator 241 can be controlled to defrost when the cumulative opening time of the freezer door after the freezing evaporator 241 defrosts exceeds a preset time. The freezing evaporator 241 can also be controlled to defrost when the operating time after the freezing evaporator 241 defrosts reaches the freezing and defrosting interval time. This prevents the refrigeration device 100 from continuously running but not defrosting for a long time when the user's usage frequency is low, thereby affecting the refrigeration of the freezer compartment 112.

[0090] Furthermore, in one embodiment of the present invention, the evaporator defrost control method further includes:

[0091] Obtaining the ice making and defrosting interval of the ice making evaporator 251 according to the ambient temperature;

[0092] When the running time of the ice-making evaporator 251 after defrosting reaches the ice-making and defrosting interval, the ice-making evaporator 251 is controlled to defrost.

[0093] In this embodiment, there may be multiple conditions for the ice-making evaporator 251 to start defrosting. When any of the defrosting conditions is detected, the ice-making evaporator 251 may be controlled to start defrosting, that is, the ice-making and defrosting heating element may be controlled to turn on. For example, the ice-making evaporator 251 may be controlled to defrost when the cumulative open time of the ice-making door 1132 or the freezer door exceeds a preset time after the ice-making evaporator 251 defrosts. Alternatively, the ice-making evaporator 251 may be controlled to defrost when the operating time after the ice-making evaporator 251 defrosts reaches the ice-making and defrosting interval time. This prevents the refrigeration device 100 from continuously operating but not defrosting for a long time when the user's usage frequency is low, thereby affecting the cooling of the ice-making chamber 113.

[0094] Furthermore, in one embodiment of the present invention, the evaporator defrost control method further includes:

[0095] Obtaining the cumulative number of ice making times of the ice maker after the ice evaporator 251 is defrosted;

[0096] When the accumulated ice-making times are greater than a preset times, the ice-making evaporator 251 is controlled to defrost.

[0097] In this embodiment, there may be multiple conditions for defrosting the ice-making evaporator 251. When any of these conditions are detected, the ice-making evaporator 251 can be controlled to start defrosting, thereby controlling the activation of the ice-making and defrosting heater. For example, the defrosting of the ice-making evaporator 251 can be controlled based on the number of ice-making cycles. When the ice-making machine operates frequently and makes ice frequently, the cooling capacity demand of the ice-making chamber 113 is high. Therefore, the likelihood of frost formation after defrosting the ice-making evaporator 251 increases.

[0098] Therefore, when it is detected that the cumulative number of ice making times of the ice maker is greater than the preset number, the ice making evaporator 251 is controlled to defrost, so that the ice making evaporator 251 can be kept in a better cooling state.

[0099] See also Figure 4 One embodiment of the present invention further provides a refrigeration device 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 evaporator defrost control method described in the above embodiment are implemented. The refrigeration device 100 also includes a communication interface 203 connected to the communication bus 204 for communicating with other devices within the refrigeration device 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 evaporator defrost control method in the above embodiment are implemented.

[0101] To sum up, the defrost control method provided by the present invention, when the freezing evaporator 241 needs to be defrosted, if the temperature difference between the freezing chamber 112 and the ice-making chamber 113 is large, the freezing evaporator 241 and the ice-making evaporator 251 are controlled to defrost synchronously to avoid the adverse effects caused by further increase in the temperature difference between the freezing chamber 112 and the ice-making chamber 113.
