[0066] The term "corresponding" may refer to an associated relationship or a binding relationship. A corresponding to B means that there is an associated relationship or a binding relationship between A and B.

[0067] Refrigeration equipment is commonly used to provide cooling capacity. Taking an air-cooled refrigerator as an example of refrigeration equipment, the air-cooled refrigerator provides cooling capacity for the compartment through a compressor, a condenser, an evaporator, a blower, etc. The blower of the air-cooled refrigerator is arranged in the air duct of the freezer compartment, and the water vapor in the refrigerator is likely to freeze on the surface of the blower. In the related art, the refrigerator includes a blower and an inner liner foam layer. A heating wire is arranged in the area of the inner liner foam layer corresponding to the blower. The air around the blower is heated, so as to defrost the blower.

[0068] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0069] In the related art, there is a certain distance between the inner liner foam layer and the blower, which results in a relatively long distance between the heating wire arranged on the inner liner foam layer and the blower, and further leads to a low heating efficiency of the heating wire for the blower, affecting the defrosting effect of the blower.

[0070] Combined with Figure 1 and Figure 2As shown in the figure, an embodiment of the present disclosure provides a refrigeration device 10, which may be a refrigerator, a freezer device, etc. The refrigeration device 10 includes an inner liner foaming layer 100 and a fan assembly 200. The fan assembly 200 includes a fan 201 and a second heating element 202. A first heating element 300 is provided in the area of the inner liner foaming layer 100 corresponding to the fan 201. It can be understood that the refrigeration device 10 further includes a compressor, a condenser, and an evaporator (not shown in the figure). The refrigeration device 10 provides cooling capacity for the compartment through the compressor, the condenser, the evaporator, and the fan, etc. The first heating element 300 and the second heating element 202 are both located near the fan 201 and can heat the air around the fan 201, so as to defrost the fan 201. It can be understood that the specific types of the first heating element 300 and the second heating element 202 are not limited, as long as they can heat the fan 201. For example, both the first heating element 300 and the second heating element 202 can adopt heating wires (such as aluminum foil). By inputting current to the first heating element 300 and the second heating element 202 to make them generate heat, the first heating element 300 and the second heating element 202 can heat the air around the fan 201, so as to defrost the fan 201.

[0071] Combined with Figure 2 As shown in the figure, on the basis of including the fan 201 and the second heating element 202, the fan assembly 200 further includes a fan bracket 203, a support member 204, and a heat insulation member 205. Both the fan 201 and the second heating element 202 are connected to the fan bracket 203, and the fan 201 and the second heating element 202 are respectively arranged on both sides of the fan bracket 203. The heat insulation member 205 is arranged on the support member 204, the second heating element 202 is located between the support member 204 and the heat insulation member 205, and the heat insulation member 205 is connected to the fan bracket 203 to clamp the second heating element 202. Specifically, the heat insulation member 205 and the second heating element 202 are respectively located on both sides of the support member 204, and the heat insulation member 205 can isolate the second heating element 202 from being dissipated to the compartment through the refrigeration air duct. Here, the material of the heat insulation member 205 can adopt polyethylene (PE).

[0072] Combined with Figure 3 As shown in the figure, the refrigeration device 10 further includes a control device 400 and a current output module 500. The control device 400 is electrically connected to the fan 201 and the current output module 500 respectively, and the first heating element 300 and the second heating element 202 are respectively electrically connected to the current output module 500. The control device 400 can control the rotation according to corresponding operating parameters, and the control device 400 can control the current output module 500 to output current to the first heating element 300 and the second heating element 202 according to corresponding current parameters.

[0073] In the embodiments of the present disclosure, the control device 400 can count time information such as the running time of the compressor of the refrigeration device 10 and the cumulative door opening time of the refrigeration device 10, and can also obtain the air temperature around the blower 201 through the temperature sensor.

[0074] Combined with the refrigeration device provided in the embodiments of the present disclosure, the embodiments of the present disclosure provide a control method for a refrigeration device. Figure 4 As shown, the control method of the refrigeration device includes:

[0075] S401, the control device obtains the running time of the compressor and compares the running time with the defrost start condition.

[0076] It can be understood that the compressor works intermittently. In the embodiments of the present disclosure, the running time of the compressor includes the cumulative running time of the compressor. The cumulative running time of the compressor refers to the sum of the running time of the compressor from a preset time point to the current moment.

[0077] In the embodiments of the present disclosure, the running time of the compressor includes the continuous running time of the compressor. The continuous running time of the compressor refers to the total duration of the compressor running in the continuous working state. Among them, the running time of the compressor obtained in S401 is the total duration of the compressor running in the current continuous working state.

[0078] S402, when the control device determines that the running time of the compressor meets the defrost start condition, it controls the first heating element and the second heating element to work for defrosting.

[0079] In some embodiments of the present disclosure, the running time of the compressor includes the cumulative running time of the compressor. When the cumulative running time of the compressor exceeds the first time threshold, it is determined that the running time of the compressor meets the defrost start condition.

[0080] In some embodiments of the present disclosure, the running time of the compressor includes the cumulative running time of the compressor. Before S402 in the embodiments of the present disclosure, the cumulative door opening time of the refrigeration device can be obtained. When the cumulative door opening time of the refrigeration device is greater than the second time threshold and the cumulative running time of the compressor exceeds the third time threshold, it is determined that the running time of the compressor meets the defrost start condition.

[0081] In some embodiments of the present disclosure, the running time of the compressor includes the continuous running time of the compressor. When the continuous running time of the compressor exceeds the fourth time threshold, it is determined that the running time of the compressor meets the defrost start condition.

[0082] In the embodiments of the present disclosure, the first time threshold, the second time threshold, the third time threshold, and the fourth time threshold can be determined according to actual design requirements. Among them, it should be ensured that the third time threshold is less than the first time threshold, and the fourth time threshold is less than the third time threshold. For example, the first time threshold is 8 hours, the second time threshold is 10 minutes, the third time threshold is 6 hours, and the fourth time threshold is 5 hours.

[0083] In the embodiments of the present disclosure, when it is determined that the operating time of the compressor meets the defrost start condition, the control device can control the current output module to output current to the first heating element and the second heating element according to the corresponding current parameters to make them generate heat, so that the first heating element and the second heating element can heat the air around the fan, thereby realizing defrosting of the fan.

[0084] S403, the control device periodically obtains the defrost time and the air temperature around the fan, and compares the defrost time and the air temperature with the defrost end condition.

[0085] In the embodiments of the present disclosure, the defrost time can be the cumulative duration from the moment when the first heating element starts working this time to the current moment, and the control device can calculate this cumulative duration in real time to obtain the defrost time.

[0086] In the embodiments of the present disclosure, a temperature sensor is provided around the fan for refrigeration setting, and the control device obtains the air temperature around the fan through the temperature sensor.

[0087] S404, when the control device determines that the defrost time and the air temperature meet the defrost end condition, it controls the first heating element and the second heating element to stop working.

[0088] In the embodiments of the present disclosure, the defrost end condition is a determination condition related to the defrost time and the air temperature around the fan. When the defrost time and the air temperature meet the defrost end condition, it can be determined that the defrosting of the fan is completed.

[0089] In some embodiments of the present disclosure, when the defrost time exceeds the fifth time threshold, it is determined that the defrost time and the air temperature meet the defrost end condition.

[0090] In some embodiments of the present disclosure, when the air temperature exceeds the temperature threshold, it is determined that the defrost time and the air temperature meet the defrost end condition.

[0091] In some embodiments of the present disclosure, when the defrost time exceeds the fifth time threshold and the air temperature exceeds the temperature threshold, it is determined that the defrost time and the air temperature meet the defrost end condition.

[0092] In the embodiments of the present disclosure, the fifth time threshold and the temperature threshold can be determined according to actual design requirements. For example, the fifth time threshold is 70 minutes, and the temperature threshold is 9 °C (Celsius).

[0093] In the embodiments of the present disclosure, when the control device determines that the defrosting time and the air temperature meet the defrosting end condition, the control device can control the current output module to stop outputting current to the first heating element and the second heating element, so that the first heating element and the second heating element stop working.

[0094] In the embodiments of the present disclosure, when a first heating element is already provided in the inner liner foaming layer of the refrigeration device, a second heating element is further added to the fan assembly including a fan. By analyzing the operating time of the compressor, when it is determined that the fan needs to be defrosted, the first heating element and the second heating element are controlled to work to transfer heat to the fan in different directions to jointly defrost the fan, thereby improving the heating efficiency of the fan and increasing the defrosting speed of the fan.

[0095] In some embodiments, when it is determined that the operating time of the compressor meets the defrosting start condition, controlling the first heating element and the second heating element to work for defrosting includes: when it is determined that the operating time of the compressor meets the defrosting start condition, controlling the first heating element to work for defrosting; after a first preset duration, acquiring the air temperature around the fan once and comparing the acquired air temperature around the fan this time with the temperature threshold; when it is determined that the acquired air temperature around the fan this time is less than the temperature threshold, controlling the second heating element to work for defrosting.

[0096] Combined with Figure 5 As shown, the embodiments of the present disclosure also provide another control method for a refrigeration device. The control method for the refrigeration device includes:

[0097] S501, the control device acquires the operating time of the compressor and compares the operating time with the defrosting start condition.

[0098] S502, when the control device determines that the operating time of the compressor meets the defrosting start condition, controlling the first heating element to work for defrosting.

[0099] As described above, the operating time of the compressor includes the cumulative operating time and the continuous operating time of the compressor. In some embodiments of the present disclosure, when it is determined that the operating time of the compressor meets the defrosting start condition, controlling the first heating element to work for defrosting includes: when it is determined that the operating time of the compressor meets the defrosting start condition, determining a first current value from multiple candidate current values based on the type of the operating time that currently meets the defrosting start condition; controlling the first heating element to work for defrosting based on the first current value.

[0100] As described above, the running time of the compressor in the embodiments of the present disclosure satisfying the defrost start condition includes the following three cases where the defrost start condition is satisfied:

[0101] Case 1 where the defrost start condition is satisfied: The cumulative running time of the compressor exceeds the first time threshold;

[0102] Case 2 where the defrost start condition is satisfied: The cumulative door opening time of the refrigeration device is greater than the second time threshold, and the cumulative running time of the compressor exceeds the third time threshold;

[0103] Case 3 where the defrost start condition is satisfied: The continuous running time of the compressor exceeds the fourth time threshold.

[0104] It can be understood that different cases where the defrost start condition is satisfied represent different frosting conditions of the blower. In the embodiments of the present disclosure, different candidate current values are respectively set for the above three cases where the defrost start condition is satisfied. Therefore, the embodiments of the present disclosure can determine the first current value from multiple candidate current values based on the type of running time that currently satisfies the defrost start condition, so that the first current value better conforms to the current frosting condition of the blower, and thus control the first heating element to work based on the first current value to better defrost the blower.

[0105] S503. After the first preset duration, the control device acquires the air temperature around the blower once, and compares the acquired air temperature around the blower this time with the temperature threshold.

[0106] S504. When the control device determines that the acquired air temperature around the blower this time is less than the temperature threshold, it controls the second heating element to work for defrosting.

[0107] In some embodiments, when it is determined that the acquired air temperature around the blower this time is less than the temperature threshold, controlling the second heating element to work for defrosting includes: when it is determined that the acquired air temperature around the blower this time is less than the temperature threshold, calculating the temperature difference between the acquired air temperature around the blower this time and the temperature threshold; determining the first current adjustment parameter of the first heating element based on the temperature difference, and adjusting the current first current value of the first heating element based on the first current adjustment parameter; determining the second current adjustment parameter of the second heating element based on the temperature difference; determining the second current value based on the initial current of the second heating element and the second current adjustment parameter, and controlling the second heating element to work for defrosting based on the second current value.

[0108] In the embodiments of the present disclosure, both the first current adjustment parameter and the second current adjustment parameter are positively correlated with the temperature difference. That is to say, the greater the temperature difference, the greater the first current adjustment parameter and the second current adjustment parameter. After the first preset duration, when it is determined that the air temperature around the fan obtained this time is less than the temperature threshold, it indicates that heating the first heating element based on the current first current value cannot defrost the fan quickly. At this time, the first current adjustment parameter and the second current adjustment parameter can be determined based on the temperature difference between the air temperature around the fan and the temperature threshold. The first current value of the first heating element is adjusted based on the first current adjustment parameter, and the second current value is determined based on the initial current of the second heating element and the second current adjustment parameter, and the second heating element is controlled to operate for defrosting based on the second current value, so as to defrost the fan more quickly with the first heating element and the second heating element after the first current value is adjusted.

[0109] In the embodiments of the present disclosure, the first current adjustment parameter may be a specific current value or a current adjustment coefficient.

[0110] When the first current adjustment is a current value, the first current adjustment is greater than 0. Adjusting the current first current value of the first heating element based on the first current adjustment parameter includes: adding the first current adjustment parameter to the current first current value of the first heating element to obtain a new first current value. It can be understood that the second heating element can be controlled to operate for defrosting based on the new first current value later.

[0111] When the first current adjustment is a current adjustment coefficient, the first current adjustment is greater than 1. Adjusting the current first current value of the first heating element based on the first current adjustment parameter includes: multiplying the first current adjustment parameter by the current first current value of the first heating element to obtain a new first current value. It can be understood that the second heating element can be controlled to operate for defrosting based on the new first current value later.

[0112] In the embodiments of the present disclosure, the second current adjustment parameter may be a specific current value or a current adjustment coefficient.

[0113] When the second current adjustment is a current value, the second current adjustment is greater than 0. Determining the second current value based on the initial current of the second heating element and the second current adjustment parameter includes: adding the initial current of the second heating element to the second current adjustment parameter to obtain the second current value.

[0114] When the second current adjustment is a current adjustment coefficient, the second current adjustment is greater than 1. Determining the second current value based on the initial current of the second heating element and the second current adjustment parameter includes: multiplying the initial current of the second heating element by the second current adjustment parameter to obtain the second current value.

[0115] As described above, the operating time of the compressor includes the cumulative operating time and the continuous operating time of the compressor. In some embodiments, determining the second current adjustment parameter of the second heating element based on the temperature difference includes: determining the second current adjustment parameter of the second heating element based on the temperature difference and the type of the operating time that currently meets the defrost start condition.

[0116] As described above, the operating time of the compressor in the embodiments of the present disclosure meeting the defrost start condition includes the following three cases where the defrost start condition is met:

[0117] Case 1 where the defrost start condition is met: The cumulative operating time of the compressor exceeds the first time threshold;

[0118] Case 2 where the defrost start condition is met: The cumulative door opening time of the refrigeration device is greater than the second time threshold, and the cumulative operating time of the compressor exceeds the third time threshold;

[0119] Case 3 where the defrost start condition is met: The continuous operating time of the compressor exceeds the fourth time threshold.

[0120] It can be understood that different cases where the defrost start condition is met represent different frosting conditions of the blower. In the embodiments of the present disclosure, different basic current adjustment parameters are respectively set for the above three cases where the defrost start condition is met. The embodiments of the present disclosure can determine the target basic current adjustment parameter from multiple basic current adjustment parameters based on the type of the operating time that currently meets the defrost start condition, and then determine the second current adjustment parameter of the second heating element according to the temperature difference and the target basic current adjustment parameter. Therefore, the embodiments of the present disclosure can determine the second current adjustment parameter that is more in line with the current frosting condition of the blower based on the temperature difference and the type of the operating time that currently meets the defrost start condition, and further determine the second current value that is more in line with the current frosting condition of the blower based on the initial current of the second heating element and the second current adjustment parameter, so as to control the second heating element to work better for defrosting the blower based on the second current value.

[0121] S505, The control device periodically acquires the defrosting time and the air temperature around the blower, and compares the defrosting time and the air temperature with the defrost end condition.

[0122] S506, When the control device determines that the defrosting time and the air temperature meet the defrost end condition, it controls the first heating element and the second heating element to stop working.

[0123] In some embodiments, when it is determined that the defrosting time and the air temperature meet the defrosting end condition, controlling the first heating element and the second heating element to stop working includes: when it is determined that the defrosting time and the air temperature meet the defrosting end condition, controlling the first heating element to stop working, continuing to control the second heating element to work based on the second current value, and controlling the blower to rotate at a threshold speed; after a target duration, controlling the second heating element to stop working, and controlling the blower to work in a normal refrigeration mode, where the threshold speed is greater than each speed of the blower in the normal refrigeration mode.

[0124] Combined with Figure 6 As shown, an embodiment of the present disclosure also provides another control method for a refrigeration device. The control method for the refrigeration device includes:

[0125] S601, the control device obtains the operating time of the compressor and compares the operating time with the defrosting start condition.

[0126] S602, when the control device determines that the operating time of the compressor meets the defrosting start condition, controlling the first heating element and the second heating element to work for defrosting.

[0127] S603, the control device periodically obtains the defrosting time and the air temperature around the blower, and compares the defrosting time and the air temperature with the defrosting end condition.

[0128] S604, when the control device determines that the defrosting time and the air temperature meet the defrosting end condition, controlling the first heating element to stop working, continuing to control the second heating element to work based on the second current value, and controlling the blower to rotate at a threshold speed.

[0129] S605, after a target duration, the control device controls the second heating element to stop working, and controls the blower to work in a normal refrigeration mode.

[0130] In the embodiment of the present disclosure, the threshold speed is greater than each speed of the blower in the normal refrigeration mode.

[0131] It can be understood that after defrosting the blower, there will still be moisture attached to the blower, which may cause the blower to frost again in a short time. Based on this, in the embodiment of the present disclosure, when it is determined that the defrosting time and the air temperature meet the defrosting end condition, the first heating element is controlled to stop working, and the second heating element is continuously controlled to work based on the second current value. In this way, the second heating element can continue to provide heat to evaporate the moisture on the blower, and at the same time, the blower is controlled to rotate at a relatively large threshold speed to blow away the moisture attached to the blower as much as possible, avoiding the blower from frosting again in a short time.

[0132] In some embodiments, the control method of the refrigeration device further includes: when it is determined that the defrosting time and the air temperature meet the defrosting end condition, determining a target duration from a plurality of candidate durations according to the defrosting time and the air temperature when the defrosting end condition is met.

[0133] Embodiments of the present disclosure set different candidate durations respectively for the above different situations where the defrosting end condition is met. Therefore, embodiments of the present disclosure can determine a target duration from a plurality of candidate durations based on the specific types of the defrosting time and the air temperature when the defrosting end condition is currently met, so that the target duration more conforms to the current defrosting situation of the blower, in order to more precisely control the working states of the second heating element and the blower based on the target duration, and remove the moisture attached to the blower with less electrical material consumption.
