[0046] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0047] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0048] Combination Figure 1-5 As shown, an embodiment of the present disclosure provides a refrigeration device, which may be a refrigerator or a freezer.

[0049] The refrigeration device includes a box body 10 and a cover shell 20 .

[0050] The box body 10 defines a refrigeration space 101; the cover shell 20 is arranged in the refrigeration space 101 and covers the bottom wall 103 of the refrigeration space 101, the cover shell 20 and the bottom wall 103 of the refrigeration space 101 together enclose a bottom air duct 201 connected to the refrigeration space 101, and the top wall of the cover shell 20 is provided with a condensation removal air outlet 202 connecting the refrigeration space 101 and the bottom air duct 201.

[0051] Optionally, the first side wall 104 is provided with a side wall air duct 1044 communicating with the bottom air duct 201 and is provided with a second air outlet 1046 communicating with the side wall air duct 1044 .

[0052] A third air port 204 is disposed on the surface of the housing 20 facing the first side wall 104 , and a fourth air port 1043 is disposed on the surface of the first side wall 104 facing the housing 20 . The third air port 204 is connected to the fourth air port 1043 , so that the bottom air duct 201 is connected to the side wall air duct 1044 .

[0053] The evaporator fan 40 and the evaporator 30 may also be located in the side wall air duct 1044 .

[0054] The inner wall surface of the side wall air duct forms an air duct cover 1047.

[0055] When the decondensation air outlet 202 is used as an air outlet, since the decondensation air outlet 202 is arranged on the top wall of the cover shell 20, the air in the bottom air duct 201 will flow upward when flowing out through the decondensation air outlet 202, thereby contacting the inner wall surface of the box body 10. When the temperature of the air flowing out from the decondensation air outlet 202 is relatively high, for example, greater than 0°C, it can play a role in removing condensation from the air duct cover 1047, so that decondensation can be achieved by using the decondensation air outlet 202.

[0056] The refrigeration device further comprises a compressor, a condenser and an evaporator 30 connected to each other. The refrigeration device further comprises an evaporation fan 40.

[0057] The refrigeration device is provided with a refrigeration air duct, and the refrigeration air duct includes a bottom air duct 201 .

[0058] The evaporator 30 and the evaporating fan 40 are both arranged in the refrigeration air duct, for example Figure 1 and Figure 3 As shown, the evaporator 30 and the evaporation fan 40 are both arranged in the bottom air duct 201. The evaporation fan 40 corresponds to the evaporator 30 and is used to drive the air in the refrigeration space 101 to flow into the refrigeration air duct and flow to the evaporator 30, and then flow from the refrigeration air duct into the refrigeration space 101 after heat exchange with the evaporator 30, so as to realize refrigeration of the refrigeration space 101.

[0059] When decondensation is removed by using the decondensation air outlet 202 , the evaporation fan 40 is turned on, and the air in the refrigeration space 101 driven by the driving force provided by the evaporation fan 40 flows into the bottom air duct 201 and flows into the refrigeration space 101 from the decondensation air outlet 202 .

[0060] Alternatively, if Figure 1 and Figure 3 As shown, the box body 10 includes a top wall 102 , a bottom wall 103 , a first side wall 104 and a second side wall 105 .

[0061] The first side wall 104 is arranged between the top wall 102 and the bottom wall 103; the second side wall 105 is arranged between the top wall 102 and the bottom wall 103, and is arranged opposite to the first side wall 104; wherein the distance between the dew condensation air outlet 202 and the first side wall 104 is smaller than the distance between the dew condensation air outlet 202 and the second side wall 105.

[0062] The second side wall 105 is disposed opposite to the first side wall 104. Therefore, the first side wall 104 and the second side wall 105 are located on opposite sides of the refrigeration space 101. Figure 1 As shown, the first side wall 104 is the rear side of the refrigeration space 101 , and the second side wall 105 is located at the front side of the refrigeration space 101 .

[0063] Compared with the second side wall 105, the decondensation vent 202 is arranged closer to the first side wall 104. In this way, the wind blown out of the decondensation vent 202 is more likely to flow to the first side wall 104, and is used to remove condensation from the air duct cover plate 1047 on the first side wall 104.

[0064] Optionally, the second side wall 105 is movably connected to the top wall 102 of the box body 10, and / or is movably connected to the bottom wall 103 of the box body 10, so that the second side wall 105 can open or close the refrigeration space 101. In other words, the second side wall 105 is a switch door, and when the switch door is opened, the user can take items out of the refrigeration space 101 or put items into the refrigeration space 101.

[0065] The longer the door is opened, the higher the ambient temperature and humidity, and the lower the temperature of the air duct cover 1047, the greater the condensation generated by the air duct cover 1047. Therefore, the condensation removal vent 202 is disposed close to the first side wall 104 to remove condensation for the air duct cover 1047.

[0066] Alternatively, if Figure 2 As shown, the inner wall surface of the first side wall 104 is provided with a guide structure 1041 to guide the wind flowing out of the decondensation air outlet 202 to flow upward, so as to achieve decondensation at various places above and below the air duct cover 1047, and avoid the situation where the wind flowing out of the decondensation air outlet 202 can only be located at the bottom of the air duct cover 1047 and cannot achieve decondensation at various places above and below the air duct cover 1047.

[0067] Alternatively, if Figure 4 and Figure 5 As shown, the guide structure 1041 includes a guide groove 1042 formed by a depression on the inner wall surface of the first side wall 104 .

[0068] The guide groove 1042 extends in the up-down direction, that is, extends in the height direction of the first side wall 104. One end of the guide groove 1042 is located at the bottom of the first side wall 104 and is connected to the dew condensation air outlet 202. The other end of the guide groove 1042 is located at the top of the first side wall 104 to guide the air outlet of the dew condensation air outlet 202 to the top of the first side wall 104.

[0069] There are multiple guide grooves 1042, and the multiple guide grooves 1042 are arranged along the width direction of the first side wall 104 (ie, the width direction of the refrigeration space, such as Figure 2 In a specific embodiment, as shown by the arrow M in FIG. Figure 4 and Figure 5 As shown, the projection of the flow guiding structure 1041 on the horizontal plane is wavy.

[0070] The flow guiding structure 1041 may also be a flow guiding rib protruding from the inner wall surface of the first side wall 104 .

[0071] The refrigeration device further comprises a cover body, which is movably provided on the de-condensation air outlet 202 and moves between a closing position for closing the de-condensation air outlet and an opening position for opening the de-condensation air outlet.

[0072] The decondensation vent 202 can be opened or closed as needed. For example, when the first side wall 104 needs to be decondensed, the cover is opened to open the decondensation vent 202. After the decondensation is completed, the cover is closed to close the decondensation vent 202. Alternatively, when the temperature in the refrigeration space 101 is high, or when the temperature difference between the top and the bottom of the refrigeration space 101 is too large, the cover is opened, and the wind flowing into the decondensation vent 202 flows to the top of the refrigeration space 101 through the guide structure 1041 to reduce the temperature of the top of the refrigeration space 101.

[0073] The cover body and the housing 20 may be connected in a rotational manner or in a sliding manner to open or close the decondensation air outlet 202 .

[0074] The refrigeration device further includes a driving device, which is drivingly connected to the cover body and is used to drive the cover body to move between the closed position and the open position. The driving device may include a motor and a gear rack mechanism drivingly connected to the motor, or a motor and a connecting rod mechanism drivingly connected to the motor, or may be other structures capable of driving the cover body to move between the open position and the closed position.

[0075] like Figure 1 As shown, the cover 20 is further provided with a fifth air outlet 203 , which is located on the surface of the cover 20 facing the second side wall 105 , and the evaporator 30 and the evaporating fan 40 are located in the bottom air duct 201 and between the fifth air outlet 203 and the decondensation air outlet 202 .

[0076] In a specific embodiment, Figure 1 As shown, under the action of the evaporating fan 40, the air in the refrigeration space 101 enters the bottom air duct 201 from the fifth air outlet 203, and after heat exchange with the evaporator 30, flows into the fourth air outlet 1043 from the third air outlet 204 to enter the side wall air duct 1044, and flows into the refrigeration space 101 from the second air outlet 1046, thereby realizing the cooling of the refrigeration space 101.

[0077] When the cover opens the decondensation air vent 202, part of the air in the bottom air duct 201 flows into the side wall air duct 1044 through the third air vent 204, and part of the air flows into the refrigeration space 101 through the decondensation air vent 202; when the cover closes the decondensation air vent 202, the air in the bottom air duct 201 cannot pass through the decondensation air vent 202, and all the air flows into the side wall air duct 1044 through the third air vent 204.

[0078] In another specific embodiment, the condensation removal air outlet 202 can also be used as an air inlet. At this time, the air flow direction in the refrigeration equipment is: Figure 3 As shown, the air in the refrigeration space 101 flows into the side wall air duct 1044 through the second air outlet 1046 , then flows into the third air outlet 204 through the fourth air outlet 1043 , and enters the bottom air duct 201 . The air in the bottom air duct 201 flows back to the refrigeration space 101 through the fifth air outlet 203 .

[0079] When the cover opens the decondensation vent 202 , the air in the refrigeration space 101 flows into the bottom air duct 201 from the decondensation vent 202 ; when the cover closes the decondensation vent 202 , the air in the bottom air duct 201 can only flow into the side wall air duct 1044 through the third air vent 204 .

[0080] like Figure 2 As shown, the orthographic projections of the second air outlet 1046 and the decondensation air outlet 202 on the horizontal plane do not completely overlap.

[0081] If the orthographic projections of the second air outlet 1046 and the decondensation air outlet 202 on the horizontal plane completely overlap, and when both the second air outlet 1046 and the decondensation air outlet 202 are used as air outlets, the wind flowing out of the decondensation air outlet 202 and the wind flowing out of the second air outlet 1046 will interfere with each other, resulting in air flow collision, causing chaotic air flow in the refrigeration space 101.

[0082] The orthographic projections of the second air outlet 1046 and the decondensation air outlet 202 on the horizontal plane do not completely overlap, that is, the second air outlet 1046 and the decondensation air outlet 202 are staggered, so that the wind flowing out of the decondensation air outlet 202 and the second air outlet 1046 are at different positions relative to the width direction of the refrigeration space 101, avoiding collision of the air flows flowing out of the two.

[0083] Optionally, there are multiple second air outlets 1046 , and the orthographic projections of the multiple second air outlets 1046 on the horizontal plane are at least partially located on two opposite sides of the orthographic projection of the decondensation air outlet 202 on the horizontal plane.

[0084] This arrangement allows the air flowing out of the second air outlet 1046 and the air flowing out of the decondensation air outlet 202 to flow to different positions in the width direction of the refrigeration space 101, thereby cooling different positions and avoiding uneven temperatures at different positions in the width direction of the refrigeration space 101.

[0085] The length direction of the dew condensation air outlet 202 extends along the width direction of the refrigeration space 101 and is smaller than the width of the refrigeration space 101 .

[0086] The plurality of second air outlets 1046 are divided into at least one group, and each group includes a plurality of second air outlets 1046. Figure 2 As shown, the orthographic projections of the second air outlet 1046 in the same group on the horizontal plane are respectively located on two opposite sides of the orthographic projections of the decondensation air outlet 202 on the horizontal plane. Along the width direction of the refrigeration space 101, the second air outlet 1046, the decondensation air outlet 202, and the second air outlet 1046 are arranged in sequence.

[0087] Alternatively, if Figure 2 As shown, the plurality of second air outlets 1046 are divided into three groups, and the three groups of second air outlets 1046 are sequentially arranged along the height direction of the refrigeration space 101 .

[0088] Alternatively, if Figure 1 As shown, the evaporator 30 and the evaporating fan 40 are both located in the bottom air duct 201, and the decondensation air outlet 202 and the second air outlet 1046 are located on the same side of the evaporating fan 40, and the evaporator 30 is located on the side of the evaporating fan 40 away from the decondensation air outlet 202 and the second air outlet 1046; the evaporating fan 40 is tilted so that the air inlet direction or the air outlet direction of the evaporating fan 40 is toward the decondensation air outlet 202 and the second air outlet 1046.

[0089] like Figure 1 As shown, when the decondensation air outlet 202 and the second air outlet 1046 are both used as air outlets, that is, the air in the bottom air duct 201 flows into the refrigeration space 101 through the decondensation air outlet 202 and / or flows into the side wall air duct 1044 through the second air outlet 1046, the air outlet direction of the evaporating fan 40 is toward the decondensation air outlet 202 and the second air outlet 1046, so that the air flowing into the bottom air duct 201 from the fifth air outlet 203 can flow to the decondensation air outlet 202 and the second air outlet 1046 at the same time under the action of the evaporating fan 40.

[0090] When both the decondensation air outlet 202 and the second air outlet 1046 are used as air inlets, that is, the air in the refrigeration space 101 flows into the bottom air duct 201 through the decondensation air outlet 202 and / or the air in the side wall air duct 1044 flows into the bottom air duct 201 through the second air outlet 1046, the air inlet direction of the evaporator fan 40 is toward the decondensation air outlet 202 and the second air outlet 1046, so that under the action of the evaporator fan 40, the air can flow into the bottom air duct 201 through the decondensation air outlet 202 and / or the second air outlet 1046.

[0091] Optionally, the first side wall 104 is movably connected to the top wall 102 or the bottom wall 103 to open or close the refrigeration space 101 .

[0092] In this solution, the first side wall 104 is equivalent to the door of the refrigeration equipment, and the user can take or store supplies through the second side wall 105. Replenishment is achieved through the door, so that the later replenished goods are located at the back of the refrigeration space 101, which can ensure the first-in-first-out of goods and avoid expiration of goods.

[0093] Optionally, the surface of the housing 20 facing the first side wall 104 includes a first setting surface 205, and the third air outlet 204 is provided on the first setting surface 205; the inner surface of the first side wall 104 includes a second setting surface 1045, and the fourth air outlet 1043 is provided on the second setting surface 1045. The first setting surface 205 and the second setting surface 1045 are both vertical surfaces; or, along the top-down direction, the first setting surface 205 and the second setting surface 1045 are both inclined toward the direction close to the axis of the refrigeration space 101.

[0094] like Figure 3 As shown, the third air vent 204 is disposed on the first setting surface 205 ; the fourth air vent 1043 is disposed on the second setting surface 1045 . When the first side wall 104 is opened, debris in the refrigeration space 101 can be prevented from entering the third air vent 204 .

[0095] Optionally, the refrigeration device further includes a heating device, which is disposed in the bottom air duct and is used to heat the air in the bottom air duct.

[0096] The heating device is arranged corresponding to the evaporator, and is used for heating the evaporator when the evaporator is frosted, so as to defrost the evaporator.

[0097] Optionally, a baffle is provided at the third air outlet, and the baffle is used to open or close the third air outlet. There are many ways to drive the baffle, for example, a motor is provided, and the motor is connected to the baffle drive to drive the baffle to move relative to the third air outlet to close or open the third air outlet. For another example, the action of the first side wall opening or closing the refrigeration space drives the baffle to move to open or close the third air outlet, and the baffle includes multiple baffles, and the multiple baffles are sequentially arranged in the third air outlet. When the first side wall is opened, the first side wall drives the multiple baffles to be laid on the third air outlet to close the third air outlet. When the first side wall is closed, the first side wall drives the multiple baffles to fold to open the third air outlet.

[0098] The refrigeration device also includes a controller, which is connected to the compressor, the evaporating fan, the heating device and the driving device, and is used to control the operation of the compressor, the evaporating fan, the heating device and the driving device.

[0099] Combination Figure 6 As shown, the embodiment of the present disclosure provides a control method, including:

[0100] Step S601, when the decondensation start condition of the air duct cover 1047 is met, the controller controls the driving device to drive the cover body to move to the open position to open the decondensation air outlet 202.

[0101] The condensation of the air duct cover plate 1047 is related to the external environment temperature and humidity, and the opening time of the first side wall 104 (i.e., the door body). In a specific embodiment, the dew point temperature is determined according to the ambient temperature and humidity. When the door body is in the open state and the temperature of the air duct cover plate 1047 is lower than the dew point temperature, condensation will appear on the air duct cover plate 1047. The condensation amount of the air duct cover plate 1047 is determined in combination with the temperature of the air duct cover plate 1047, the ambient temperature and humidity, and the opening time of the door body.

[0102] The lower the temperature of the air duct cover 1047, the higher the ambient temperature and humidity, and the longer the door is opened, the greater the condensation amount of the air duct cover 1047.

[0103] When the condensation amount on the air duct cover 1047 is greater than the preset condensation amount, it is determined that the air duct cover 1047 decondensation start condition is met. In step S601, when the air duct cover 1047 decondensation start condition is met, the driving device is controlled to drive the cover to the open position to open the decondensation air port 202.

[0104] The air duct cover 1047 is completely located above the decondensation port, or most of it is located above the decondensation port. When the decondensation port is opened, the air in the bottom air duct 201 flows upward from the decondensation port and flows to the air duct cover 1047, so that the air duct cover 1047 can be decondensed.

[0105] Optionally, the refrigeration device further includes a heating device, and the control method further includes:

[0106] Step S701, when the air duct cover 1047 decondensation start condition is met, the controller detects the temperature in the refrigeration space 101;

[0107] Step S702, when the temperature in the refrigeration space 101 is lower than a preset temperature, the controller controls the heating device to turn on;

[0108] Step S703: when the temperature in the refrigeration space 101 is greater than or equal to a preset temperature, the controller controls the heating device to be turned off.

[0109] Due to the existence of the fifth air outlet 203, the refrigeration space 101 is connected to the bottom air duct 201. When the temperature in the refrigeration space 101 is greater than or equal to the preset temperature, the temperature in the refrigeration space 101 is high, the temperature in the bottom air duct 201 is also high, and the temperature of the air flowing out of the decondensation air outlet 202 is also high, so that the air flowing out of the decondensation air outlet 202 can be used to remove condensation from the air duct cover 1047 without turning on the heating device.

[0110] When the temperature in the refrigeration space 101 is lower than the preset temperature, the temperature in the refrigeration space 101 is low, and the temperature in the bottom air duct 201 is also low. The heating device needs to be turned on. The heating device heats the air in the bottom air duct 201, and the heated air flows out from the decondensation air outlet 202 to remove condensation from the air duct cover 1047.

[0111] Optionally, when the decondensation start conditions of the air duct cover 1047 are met, the third air outlet can be closed by a baffle so that the air in the bottom air duct 201 flows out from the decondensation air outlet 202 for decondensation of the air duct cover 1047.

[0112] Step S601 may be before step S701 or after S701, for example, between S701 and S702 or synchronously with S702 or after S702, or between S701 and S703 or synchronously with S703 or after S703.

[0113] The preset temperature can be 0°C.

[0114] Combination Figure 7 As shown, the embodiment of the present disclosure provides another control method, including:

[0115] Step S701, when the air duct cover 1047 decondensation start condition is met, the controller detects the temperature in the refrigeration space 101;

[0116] Step S7002, when the temperature in the refrigeration space 101 is lower than the preset temperature during the execution of step S702, the controller controls the heating device to turn on, and also executes step S601 to control the driving device to drive the cover to move to the open position to open the decondensation air outlet 202;

[0117] Step S7003, when the temperature in the refrigeration space 101 is greater than or equal to the preset temperature during step S702, the heating device is controlled to be turned off, and step S601 is also executed to control the driving device to drive the cover to the open position to open the decondensation vent 202.

[0118] Optionally, the control method further includes:

[0119] Step S801, when the decondensation start condition of the air duct cover 1047 is met, the controller controls the evaporation fan 40 to turn on.

[0120] The evaporation fan 40 can accelerate the air in the bottom air duct 201 to flow out from the decondensation outlet, thereby accelerating the decondensation process of the air duct cover 1047.

[0121] The order of step S801 and steps S701, S702, and S703 can be arbitrary. Step S80 can be before step S701, or after S701, for example, between S701 and S702, or synchronously with S702, or after S702, or between S701 and S703, or synchronously with S703, or after S703.

[0122] Combination Figure 8 As shown, the embodiment of the present disclosure provides another control method, including:

[0123] Step S701, when the air duct cover 1047 decondensation start condition is met, the controller detects the temperature in the refrigeration space 101;

[0124] Step S8002, when the temperature in the refrigeration space 101 is lower than the preset temperature during the execution of step S702, the controller controls the heating device to turn on, and also executes step S601 to control the driving device to drive the cover to move to the open position to open the decondensation air outlet 202, and executes step S801 to control the evaporation fan 40 to turn on;

[0125] Step S8003, when executing step S703 and the temperature in the refrigeration space 101 is greater than or equal to the preset temperature, while controlling the heating device to be turned off, step S601 is also executed to control the driving device to drive the cover body to move to the open position to open the decondensation air outlet 202, and step S801 is executed to control the evaporation fan 40 to be turned on.

[0126] After step S601, the control method further includes:

[0127] When the decondensation termination condition of the air duct cover 1047 is met, the evaporation fan 40 is controlled to be turned off, the driving device is controlled to drive the cover body to close the decondensation air outlet 202, and the heating device is controlled to be turned off.

[0128] When the amount of condensation on the air duct cover 1047 is less than the preset condensation amount, or the decondensation time reaches the preset decondensation time, it is considered that the decondensation termination condition of the air duct cover 1047 is met.

[0129] Combination Fig. 9 As shown, the embodiment of the present disclosure provides another control method, further comprising:

[0130] Step S901 , when the defrosting start condition of the evaporator 30 is met, the controller controls the heating device to start and controls the driving device to drive the cover to move to the closed position to close the decondensation air outlet 202 .

[0131] When the operating time of the refrigeration equipment reaches the preset operating time of the refrigeration equipment, or the continuous operating time of the compressor reaches the preset compressor operating time, or the cumulative opening time of the door body or the switch door (i.e., the second side wall) reaches the preset opening time, it is determined that the defrosting start conditions of the evaporator 30 are met.

[0132] When the defrosting start conditions of the evaporator 30 are met, the heating device is controlled to start, the evaporator 30 is defrosted, and the decondensation air vents 202 are closed to prevent excessive heat from entering the refrigeration space 101 through the decondensation air vents 202 and causing the temperature in the refrigeration space 101 to rise, and the compressor and the evaporating fan 40 are controlled to stop running.

[0133] When the defrosting start condition of the evaporator 30 is met, the baffle can also be controlled to close the third air outlet to prevent excessive heat from entering the side wall air duct through the third air outlet.

[0134] When the defrosting end condition of the evaporator 30 is met (for example, the defrosting time reaches the preset defrosting time or the temperature of the evaporator 30 reaches the preset evaporator 30 temperature), the heating device is controlled to be turned off.

[0135] Step S901 is a control method for defrosting the evaporator 30, and step S601 is a control method for removing condensation from the air duct cover 1047. Therefore, there is no order between the two. When the decondensation start condition of the air duct cover 1047 is met, step S601 is executed; when the defrosting start condition of the evaporator 30 is met, step S901 is executed. If both the decondensation start condition of the air duct cover 1047 and the defrosting start condition of the evaporator 30 are met, step S901 is executed first, and step S601 is executed after defrosting is completed.

[0136] After step S901 controls the heating device to start and controls the driving device to drive the cover to move to the closed position to close the decondensation air outlet 202 when the defrosting start condition of the evaporator 30 is met, the control method further includes:

[0137] Step S1002 , when the amount of frost on the evaporator 30 is greater than the preset amount of frost, after the evaporator 30 is defrosted, the controller controls the driving device to drive the cover to move to the open position, and opens the decondensation vent 202 .

[0138] When the amount of frost on the evaporator 30 is greater than the preset amount of frost, the air duct cover 1047 and the side wall air duct are also at risk of frost. Therefore, the decondensation air outlet 202 is controlled to open, the evaporating fan 40 is controlled to run at a low speed, the heating device is controlled to be turned off or the operating power of the heating device is reduced, and the residual heat in the bottom air duct 201 is used to defrost the air duct cover 1047 and the side wall air duct.

[0139] In the case where the amount of frost on the evaporator 30 is greater than the preset amount of frost, the amount of frost on the evaporator 30 refers to the amount of frost on the evaporator 30 before the defrosting is started, and whether the amount of frost is greater than the preset amount of frost can be determined based on the thickness of the frost layer on the evaporator 30 or the duration of the defrosting of the evaporator 30. If the thickness of the frost layer is greater than the preset thickness of the frost layer or the duration of the defrosting of the evaporator 30 is greater than the preset defrosting duration of the evaporator 30, it is determined that the amount of frost on the evaporator 30 is greater than the preset amount of frost. If not, it is determined that the amount of frost on the evaporator 30 is not greater than the preset amount of frost.

[0140] When the amount of frost on the evaporator 30 is less than or equal to the preset amount of frost, after the evaporator 30 is defrosted, the refrigeration equipment can operate normally without opening the decondensation air outlet 202 to defrost the side wall air duct and the air duct cover 1047.

[0141] Combination Fig.10 As shown, the embodiment of the present disclosure provides another control method, further comprising:

[0142] Step S1001, when the defrosting start condition of the evaporator 30 is met, the controller controls the heating device to start and controls the driving device to drive the cover to move to the closed position to close the decondensation air outlet 202;

[0143] Step S1002 , when the amount of frost on the evaporator 30 is greater than the preset amount of frost, after the evaporator 30 is defrosted, the controller controls the driving device to drive the cover to move to the open position, and opens the decondensation vent 202 .

[0144] There is no order between step S1002 and step S601. When the decondensation start condition of the air duct cover 1047 is met, step S601 is executed; when the amount of frost on the evaporator 30 is greater than the preset amount and defrosting is completed, step S1002 is executed. If the decondensation start condition of the air duct cover 1047 and the condition that the amount of frost on the evaporator 30 is greater than the preset amount and defrosting is completed are met at the same time, the decondensation air outlet 202 needs to be opened in both step S601 and step S1002, so both can be performed at the same time.

[0145] The distance between the dew condensation air outlet 202 and the door body (first side wall 104) is smaller than the distance to the side of the box body opposite to the door body (ie, the second side wall). In other words, the distance between the dew condensation air outlet 202 and the first side wall 104 is smaller than the distance to the second side wall.

[0146] The control method further comprises:

[0147] Step S1101, when the door body is in an open state, the driving device is controlled to drive the cover body to move to an open position, so as to open the decondensation air outlet 202 to form an air curtain.

[0148] When the decondensation vents 202 are opened, the air in the bottom air duct 201 flows upward through the decondensation vents 202 to form an air curtain, which can isolate the refrigeration space 101 from the external environment, thereby preventing the cold air in the refrigeration space 101 from leaking out.

[0149] There is no order between step S1101 and step S601. When the decondensation start condition of the air duct cover 1047 is met, step S601 is executed; when the door body is in the open state, step S1101 is executed. If the decondensation start condition of the air duct cover 1047 and the door body are in the open state are met at the same time, step S1101 is executed first, and when the door body is in the closed state, step S601 is executed, that is, step S601 is executed when the door body is in the closed state.

[0150] Combination Fig.11 As shown, the embodiment of the present disclosure provides another control method, including:

[0151] Step S1101, when the door body is in an open state, controlling the driving device to drive the cover body to move to an open position, so as to open the decondensation air outlet 202 to form an air curtain;

[0152] Step S601, when the decondensation start condition of the air duct cover 1047 is met, the driving device is controlled to drive the cover body to move to the open position to open the decondensation air outlet 202.

[0153] The control method also includes:

[0154] Step S1201, when the difference between the temperature at the top and the temperature at the bottom of the refrigeration space 101 is greater than a preset difference or the temperature in the refrigeration space 101 is greater than a preset refrigeration temperature, the controller controls the driving device to drive the cover to move to an open position to open the decondensation vent 202.

[0155] When the de-condensation air outlet 202 is closed, the air in the side wall air duct flows out to the refrigeration space 101 through the second air outlet 1046, thereby refrigerating the refrigeration space 101. When the difference between the temperature at the top and the temperature at the bottom of the refrigeration space 101 is greater than the preset difference or the temperature in the refrigeration space 101 is greater than the preset refrigeration temperature, it means that the refrigeration demand cannot be met by relying solely on the second air outlet 1046. Therefore, the de-condensation air outlet 202 is opened, and the compressor and the evaporating fan 40 are controlled to provide operating power.

[0156] There is no order between step S1201 and step S601. When the decondensation start-up condition of the air duct cover 1047 is met, step S601 is executed; when the difference between the temperature at the top and the temperature at the bottom of the refrigeration space 101 is greater than the preset difference or the temperature in the refrigeration space 101 is greater than the preset refrigeration temperature, step S1201 is executed. If the decondensation start-up condition of the air duct cover 1047 and the difference between the temperature at the top and the temperature at the bottom of the refrigeration space 101 is greater than the preset difference or the temperature in the refrigeration space 101 is greater than the preset refrigeration temperature are met at the same time, if the temperature in the refrigeration space 101 is greater than or equal to the preset temperature at this time, step S1201 is executed first.

[0157] Combination Fig.12 As shown, the embodiment of the present disclosure provides another control method, including:

[0158] Step S1201, when the difference between the temperature at the top and the temperature at the bottom of the refrigeration space 101 is greater than a preset difference or the temperature in the refrigeration space 101 is greater than a preset refrigeration temperature, the controller controls the driving device to drive the cover to move to the open position to open the decondensation vent 202;

[0159] Step S601, when the decondensation start condition of the air duct cover 1047 is met, the driving device is controlled to drive the cover body to move to the open position to open the decondensation air outlet 202.
