[0045] Combination Figures 9 to 13 As shown, the embodiment of the present disclosure provides a control method for a refrigeration device 100 .

[0046] The refrigeration device 100 may be a refrigerator or a freezer. The present application will be specifically described below using a freezer as an example.

[0047] The refrigeration device 100 includes a housing 401 , a damper 419 , a driving device and an evaporating fan 416 .

[0048] The box body includes a top wall 402, a bottom wall 403, and a side wall disposed between the top wall 402 and the bottom wall 403. The side wall includes a first side wall section and a second side wall section 406 located below the first side wall section. The first side wall section and the second side wall section 406 are located on the same side of the refrigeration space 420, for example, both are located on the rear side, front side, left side or right side of the refrigeration space 420. Fig.10 As shown, the first side wall segment and the second side wall segment 406 are located at the rear side of the refrigerated space 420 .

[0049] The first side wall section is provided with a door body 411, the second side wall section 406 is provided with a side wall air duct 407, and the first air outlet 409 of the side wall air duct 407 is located on the top wall 402 of the first side wall section, that is, located on the surface of the second side wall section 406 facing the first side wall section.

[0050] The damper 419 is movably connected to the second side wall section 406 to move between a covering position of the first air outlet 409 and an opening position of the first air outlet 409. The driving device is connected to the damper 419 to drive the damper 419 to move between the covering position and the opening position.

[0051] like Fig.11 In the case of Fig.12 , the cover is in the covering position.

[0052] The first air outlet 409 includes a first air outlet area 417 and a second air outlet area 418, and the air door 419 is disposed in the second air outlet area 418. Fig.12 , the damper 419 covers the second air outlet area 418, but does not cover the first air outlet area 417, and the first air outlet area 417 can still achieve communication between the side wall air duct 407 and the outside. Fig.11 The air door 419 opens the second air outlet area 418 but still does not cover the first air outlet area 417 .

[0053] Optionally, the number of the first air outlet area 417 is one or more. When there is one, the first air outlet area 417 is located on one side of the second air outlet area 418. When there are multiple first air outlet areas 417, the multiple first air outlet areas 417 are located on two opposite sides of the second air outlet area 418.

[0054] Optionally, the second air outlet area 418 is located in the middle of the first air outlet 409, and the plurality of first air outlet areas 417 are located on opposite sides of the second air outlet area 418. The first air outlet 409 extends along the width direction of the refrigeration device 100. Taking the first side wall section and the second side wall section 406 as an example of being located at the rear side of the refrigeration space 420, the first air outlet 409 extends along the left-right direction, wherein the left-right direction is the left-right direction of the user when the user normally uses the refrigeration device 100. The second air outlet area 418 is located in the middle of the extension direction of the first air outlet 409, and the first air outlet area 417 and the second air outlet area 418 are arranged along the extension direction of the first air outlet 409, as shown in FIG. Fig.12 As shown, there are two first air outlet areas 417 , and the two first air outlet areas 417 are respectively located on the left and right sides of the second air outlet area 418 .

[0055] In this way, when the air door 419 is in the covering position, an air curtain can be formed from the plurality of first air outlet areas 417 to ensure the temperature balance of the refrigeration space 420 in the width direction.

[0056] The damper 419 is slidably connected or rotationally connected to the second side wall section 406, and the driving device is drivingly connected to the damper 419 to drive the damper 419 to move between the covering position and the opening position.

[0057] The driving device includes a motor and a transmission mechanism. The transmission mechanism includes a gear rack mechanism or a connecting rod mechanism or other mechanisms that can meet the movement trajectory of the damper 419, which is not limited here.

[0058] The refrigeration device 100 also includes a connected compressor, a condenser and an evaporator 415. The evaporator fan 416 is arranged opposite to the evaporator 415 to drive the air in the refrigeration space 420 to flow to the evaporator 415, and then flow into the refrigeration space 420 again after heat exchange with the evaporator 415.

[0059] The door body 411 is provided with a door body air duct 412, and the door body air duct 412 is provided with a third air outlet 414. The air inlet 413 of the door body air duct is provided on the bottom wall 403 of the first side wall section, that is, the surface of the first side wall section facing the second side wall section 406, and the air inlet 413 of the door body air duct is connected to the first air outlet 409.

[0060] In a specific embodiment, the evaporator 415 and the evaporation fan 416 are located in the side wall air duct 407. A return air port 408 is provided at the bottom of the side wall air duct 407. When the evaporation fan 416 is running, the air in the refrigeration space 420 is driven to enter the side wall air duct 407 from the return air port 408 and flow out from the first air outlet 409.

[0061] A first detection device may be provided on the refrigeration device 100 to determine the state of the door body 411, which may include an open state and a closed state. The first detection device may be a displacement sensor or an angle sensor, which determines whether the door body 411 is in a closed state or an open state by detecting the distance between the door body 411 and the cabinet 401 or the opening angle of the door body 411.

[0062] A second detection device and a third detection device are also provided in the refrigeration space 420 . The second detection device is used to detect the temperature at the top of the refrigeration space 420 , and the third detection device is used to detect the temperature at the bottom of the refrigeration space 420 .

[0063] The refrigeration device 100 further includes a controller, which is connected to the first detection device, the second detection device, the third detection device, the evaporation fan 416, and the driving device, and is used to control the evaporation fan according to the detection information of the detection device.

[0064] like Figure 1 As shown, the control method includes:

[0065] In step S101 , when the door body 411 is in an open state, the controller controls the evaporation fan 416 to operate and controls the driving device to operate according to parameter information in the refrigeration space 420 to adjust the opening of the damper 419 .

[0066] When the door body 411 is in the open state, the evaporator fan 416 is controlled to run. Driven by the evaporator fan 416, the air in the refrigeration space 420 enters the side wall air duct 407 through the air outlet and flows out from the first air outlet area 417, forming an upward wind curtain, which plays a role in isolating the inside of the refrigeration space 420 from the outside world, thereby reducing the dissipation of cold air in the refrigeration space 420 caused by the opening of the door body 411.

[0067] When the door body 411 is in the open state, the driving device is controlled to work according to the parameter information in the refrigeration space 420 to adjust the opening of the damper 419. After the opening of the damper 419 is adjusted, the size of the wind curtain formed by the second air outlet area 418 will change. In this way, the size of the wind curtain formed by the second air outlet 410 can match the parameter information of the refrigeration space 420, which can not only ensure that the environment in the refrigeration space 420 meets the requirements, but also achieve energy saving and consumption reduction.

[0068] The parameter information includes a temperature change rate. In step S101, the driving device is controlled to work according to the parameter information in the refrigeration space 420 to adjust the opening of the damper 419, including:

[0069] The operation of the driving device is controlled according to the temperature change rate in the refrigeration space 420 , wherein the greater the temperature change rate, the greater the opening of the damper 419 is controlled to be.

[0070] When the door body 411 is in the open state, the temperature in the refrigeration space 420 will inevitably rise. When the temperature change rate (rising speed) in the refrigeration space 420 is greater than the preset rate, the control driving device drives the damper 419 to move toward the open position. When the temperature change rate (rising speed) in the refrigeration space 420 is less than or equal to the preset rate, the control driving device drives the damper 419 to the covering position.

[0071] The greater the temperature change rate (rising speed) in the refrigeration space 420, the larger the opening angle of the control damper 419, the smaller the blocking area of ​​the damper 419 on the second air outlet area 418, and the larger the wind curtain generated by the second air outlet area 418, and the more it can prevent the temperature in the refrigeration space 420 from rising.

[0072] Combination Figure 2 As shown, the embodiment of the present disclosure provides another control method, including:

[0073] In step S201, when the door body 411 is in an open state, the controller controls the evaporation fan 416 to operate and controls the driving device to operate according to the temperature change rate in the refrigeration space 420, wherein the greater the temperature change rate, the greater the control of the driving device to increase the opening of the damper 419.

[0074] Optionally, the second side wall section 406 is provided with a second air outlet 410 connected to the side wall air duct 407, and the second air outlet 410 is lower than the first air outlet 409. The control method further includes:

[0075] When the door body 411 is in the open state, the second air outlet 410 is controlled to be opened.

[0076] The second air outlet 410 is disposed on the inner wall of the side wall air duct 407 . The cold air flowing out of the second air outlet 410 forms an air curtain and flows toward the bottom of the refrigeration space 420 , mainly used to cool the bottom of the refrigeration space 420 and maintain the temperature of the bottom of the refrigeration space 420 .

[0077] Combination Figure 3 As shown, the embodiment of the present disclosure provides another control method, including:

[0078] In step S301, when the door body 411 is in an open state, the controller controls the evaporation fan 416 to operate, controls the driving device to operate according to parameter information in the refrigeration space 420, so as to adjust the opening of the damper 419, and controls the second air outlet 410 to open.

[0079] Optionally, the parameter information includes a temperature difference between the top and the bottom of the refrigeration space 420. In step S101, the driving device is controlled to operate according to the parameter information in the refrigeration space 420 to adjust the opening of the damper 419, including:

[0080] The operation of the driving device is controlled according to the temperature difference between the top and the bottom of the refrigeration space 420 , wherein the larger the temperature difference is, the larger the opening of the damper 419 is controlled to be.

[0081] The first side wall section is located at the top of the box body 401, the second side wall section 406 is located at the bottom of the box body 401, and the door body 411 is arranged on the first side wall section. Therefore, when the door body 411 is opened, the temperature at the top of the refrigeration space 420 is more affected, and the temperature at the top of the refrigeration space 420 rises faster.

[0082] The greater the temperature difference between the top and bottom of the refrigeration space 420, the higher the top temperature. When the temperature difference between the top and bottom of the refrigeration space 420 is greater than the preset temperature difference, the control drive device opens the damper 419 to move toward the open position, and the air volume is redistributed at the first air outlet 409 and the second air outlet 410. When the temperature difference between the top and bottom of the refrigeration space 420 is less than or equal to the preset temperature difference, the damper 419 is controlled to be in the covering position.

[0083] The larger the opening of the air door 419 is, the more air will flow to the second air outlet 410, and the air volume flowing out of the first air outlet 409 will decrease, that is, the air curtain (such as Fig.10 The wind curtain 2) is enlarged, and the wind curtain formed at the first air outlet 409 (such as Fig.10 The wind curtain 1) is reduced to prevent the temperature at the top of the refrigeration space 420 from rising too quickly when the cooling capacity is constant.

[0084] The greater the temperature difference between the top and bottom temperatures of the refrigeration space 420, the greater the opening of the damper 419, that is, the greater the degree of opening, the larger the wind curtain formed by the second air outlet 410, forming a long wind curtain, and strengthening the barrier to the external ambient temperature to avoid the top temperature in the refrigeration space 420 being too high.

[0085] Combination Figure 4 As shown, the embodiment of the present disclosure provides another control method, including:

[0086] Step S401, when the door body 411 is in an open state, the controller controls the evaporation fan 416 to operate and controls the driving device to operate according to the temperature difference between the top and the bottom of the refrigeration space 420, wherein the greater the temperature difference, the greater the control of the driving device to increase the opening of the damper 419.

[0087] Optionally, the door opening state includes during and after the door is opened, when the door body 411 is in the door opening state, the evaporation fan 416 is controlled to operate and the driving device is controlled to operate according to the parameter information in the refrigeration space 420 to adjust the opening of the damper 419, including:

[0088] When the door body 411 is opened, the evaporation fan 416 is controlled to operate and the driving device is controlled to drive the damper 419 to move to the covering position;

[0089] After the door body 411 is opened, the evaporation fan 416 is controlled to operate and the driving device is controlled to operate according to parameter information in the refrigeration space 420 to adjust the opening of the air door 419 .

[0090] If the displacement of the door body 411 relative to the box body 401 or the change amplitude of the opening angle of the door body 411 is less than the preset amplitude within the preset time length, it means that the door body 411 has not moved relative to the box body 401 or the movement amplitude is small, and the door body 411 is judged to be in the opened state; if the change amplitude is greater than or equal to the preset amplitude within the preset time length, it means that the movement amplitude of the door body 411 relative to the box body 401 is large, and the door body 411 is judged to be in the opening process.

[0091] During the opening process of the door body 411, since the door body 411 is opened for a short time, the temperature change in the refrigeration space 420 is small. Therefore, the evaporator fan 416 is controlled to run and the driving device is controlled to drive the damper 419 to move to the covering position. The wind curtain formed by the first air outlet area 417 can prevent the top of the refrigeration space 420 from heating up too quickly, thereby reducing the energy consumption of the refrigeration equipment 100 while meeting the temperature requirements in the refrigeration space 420.

[0092] After the door body 411 is opened, since the door body 411 has been open for a long time and / or the opening range of the door body 411 is large, there is a greater risk that the top temperature of the refrigeration space 420 will increase. Therefore, the evaporator fan 416 is controlled to operate and the drive device is controlled to operate according to the parameter information in the refrigeration space 420 to adjust the opening of the damper 419.

[0093] Combination Figure 5 As shown, the embodiment of the present disclosure provides another control method, including:

[0094] Step S501, when the door body 411 is opened, the controller controls the evaporation fan 416 to operate and controls the driving device to drive the damper 419 to move to the covering position;

[0095] In step S502 , after the door body 411 is opened, the controller controls the evaporation fan 416 to operate and controls the driving device to operate according to parameter information in the refrigeration space 420 to adjust the opening of the air door 419 .

[0096] In step S502, the driving device is controlled to operate according to the parameter information in the refrigeration space 420 to adjust the opening of the damper 419. The driving device can be controlled to operate according to the temperature difference between the top and the bottom of the refrigeration space 420, wherein the larger the temperature difference, the more the driving device is controlled to increase the opening of the damper 419. Alternatively, the driving device can be controlled to operate according to the temperature difference between the top and the bottom of the refrigeration space 420, wherein the larger the temperature difference, the more the driving device is controlled to increase the opening of the damper 419.

[0097] Optionally, when the door body 411 is in a closed state, the set temperature in the refrigeration space 420 is a first set temperature, and the control method further includes:

[0098] When the door body 411 is in an open state, the set temperature in the refrigeration space 420 is adjusted to a second set temperature, wherein the second set temperature is greater than the first set temperature;

[0099] When the temperature in the refrigeration space 420 is greater than the second set temperature, the compressor is controlled to start.

[0100] When the door body 411 is in an open state, the set temperature in the refrigeration space 420 is increased. When the temperature in the refrigeration space 420 is greater than the second set temperature, the compressor is controlled to be turned on. When the temperature in the refrigeration space 420 is less than or equal to the second set temperature, the compressor is controlled to be turned off.

[0101] When the door 411 is in the open state, the actual temperature in the refrigeration space 420 will inevitably rise. If the first set temperature is still used at this time, the compressor will be frequently turned on. However, after the compressor is turned on, since the door 411 is in the open state, the coldness in the refrigeration space 420 will be lost to the external environment. Therefore, although the compressor consumes a lot of energy, its actual contribution rate to the temperature reduction in the refrigeration space 420 is not high.

[0102] Therefore, when the door body 411 is in the open state, the set temperature in the refrigeration space 420 is increased to the second set temperature, which can avoid frequent startup of the compressor and reduce the energy consumption of the refrigeration device 100.

[0103] like Figure 6 As shown, the embodiment of the present disclosure provides another control method, including:

[0104] Step S601, when the door body 411 is in an open state, the controller controls the evaporation fan 416 to operate and controls the driving device to operate according to the parameter information in the refrigeration space 420 to adjust the opening of the damper 419, and adjust the set temperature in the refrigeration space 420 to a second set temperature, wherein the second set temperature is greater than the first set temperature;

[0105] Step S602: When the temperature in the refrigeration space 420 is greater than the second set temperature, the controller controls the compressor to start.

[0106] Optionally, the control method further includes:

[0107] When the door body 411 is in the closed state, the driving device is controlled to operate according to the temperature difference between the top and the bottom of the refrigeration space 420 , wherein the larger the temperature difference is, the larger the opening of the damper 419 is controlled to be.

[0108] If the temperature is greater than the preset threshold, it means that the top temperature of the refrigeration space 420 is high, and the control driving device drives the damper 419 to move toward the open position to increase the air volume of the second air outlet 410 and reduce the air volume of the first air outlet 409, so that the top and bottom of the refrigeration space 420 can reach a uniform temperature as soon as possible. If the temperature is less than or equal to the preset threshold, the damper 419 is controlled to be in the covering position.

[0109] like Figure 7 As shown, the embodiment of the present disclosure provides another control method, including:

[0110] Step S701, when the door body 411 is in an open state, the controller controls the evaporation fan 416 to operate and controls the driving device to operate according to parameter information in the refrigeration space 420 to adjust the opening of the air door 419;

[0111] Step S702, when the door body 411 is in the closed state, the controller controls the driving device to operate according to the temperature difference between the top and the bottom of the refrigeration space 420, wherein the larger the temperature difference is, the larger the opening of the damper 419 is controlled to be.

[0112] The refrigeration device 100 also includes a switch door 421. In a specific embodiment, the switch door 421 is located on the front side wall of the refrigeration device 100. The first side wall section and the second side wall section 406 are the rear side walls of the refrigeration space 420, that is, the door body 411 is located on the rear side wall of the refrigeration space 420.

[0113] The user can take or store articles by opening and closing the door 421. The door 411 is used to replenish the goods, so that the goods replenished later are located at the rear side of the refrigeration space 420, so as to realize the first-in-first-out of the articles and avoid the articles from being expired.

[0114] When the switch door 421 is in an open state and the door body 411 is in a closed state, the compressor and the evaporating fan 416 stop running.

[0115] When the door body 411 is in the closed state and the switch door 421 is in the closed state, the operation of the evaporator fan 416 and the compressor is controlled according to the set temperature in the refrigeration space 420. For example, when the temperature of the refrigeration space 420 is greater than the first set temperature, the evaporator fan 416 and the compressor are controlled to operate, and when the temperature of the refrigeration space 420 is less than or equal to the first set temperature, the evaporator fan 416 and the compressor are controlled to be turned off.
