Because the temperature-controlled compartment 114 is provided with the air supply outlet 117 and the air return outlet 118, the temperature-controlled compartment 114 realizes the circulation with the air outside the temperature-controlled compartment 114 through the air supply outlet 117 and the air return outlet 118, the air outside the temperature-controlled compartment 114 can enter the temperature-controlled compartment 114 from the air supply outlet 117 and flow out from the air return outlet 118, and in the process, the heat exchange between the inside and the outside of the temperature-controlled compartment 114 can be realized through the flow of the air, therefore, the temperature of the temperature-controlled compartment 114 can be adjusted by controlling the circulation state of the air flow channel, in the embodiment of the invention, the communication state of the air return outlets 118 of more than two temperature-controlled compartments 114 is controlled by the communication outlet 310 on the turntable 116, based on the communication state, the driving device 115 controls the turntable 116 to rotate according to the temperature control request, so that the communication outlet 310 is communicated with the air return outlet 118 of the temperature-controlled compartment 114 corresponding to the temperature-controlled compartment 114, and a passage for the circulation of the air is formed between the air supply outlet 117 and the air return outlet 118 of the corresponding temperature-controlled compartment 114, thereby achieving the adjustment of the temperature controlled compartment 114.

Further, in the embodiment of the present invention, the communication port 310 on the control dial 116 is in communication with the air return port 118 of the temperature-controlled compartment 114, which needs to control the temperature, so as to control the temperature of the temperature-controlled compartment 114, and therefore, the shape or area of the communication port 310 is different from the size of the air return port 118, which does not cause the situation that the temperature of the temperature-controlled compartment 114 cannot be controlled. Based on this, the embodiment of the present invention does not limit the shape of the communication port 310, the communication port 310 may be in a fan shape, a square shape, a circular shape, or other irregular shapes, or the area of the communication port 310 is not limited, and the area of the communication port 310 may be larger than the air return opening 118 or smaller than the air return opening 118.

It should be noted that, if the communication port 310 and the air return opening 118 have the same shape, but the area of the communication port 310 is smaller than that of the air return opening 118, the air flowing out of the air return opening 118 is affected by the flux of the communication port 310, so as to reduce the temperature control efficiency of the temperature-controlled compartment 114, and therefore, in an embodiment of the present invention, the shape and the area of the communication port 310 and the air return opening 118 may be set to be the same, and when the communication port 310 and the air return opening 118 are controlled to be communicated, since the shape and the size of the communication port 310 and the air return opening 118 are the same and are matched to be communicated, the air flowing out through the air return opening 118 can flow out completely without affecting the air flowing out speed.

The number of the communication ports 310 provided on the turntable 116 may be one or more than two, and when the number of the communication ports 310 provided on the turntable 116 is one, the communication ports 310 can be controlled to be communicated with the air return openings 118 of the plurality of temperature control compartments 114 one by one, so as to realize temperature control of the plurality of temperature control compartments 114, in addition, more than two communication ports 310 may be provided, and the communication ports 310 are used for simultaneously controlling the communication state of the air return openings 118 of the more than two temperature control compartments 114, so as to realize temperature control of the plurality of temperature control compartments 114.

The connection between the driving device 115 and the turntable 116 includes:

in the first aspect, the driving device 115 is provided with a rotating shaft, the rotating shaft can be connected with the center of the turntable 116, and the turntable 116 can be driven to rotate by the rotation of the rotating shaft, so that the control of the turntable 116 is realized.

In a second aspect, the driving device 115 is provided with a rotating wheel, and the rotating wheel is connected with the edge of the rotating disc 116, and the edge motion can be controlled through the rotation of the rotating wheel, so as to drive the rotating disc 116 to rotate.

The connection between the driving device 115 and the turntable 116 is not limited to the above connection, and may be another connection. The drive device 115 may be a servo motor, stepper motor, or other rotating device.

Further, the projection of the return air opening 118 in the direction of the turntable 116 overlaps with the rotation path of the communication opening 310. When the turntable 116 rotates, the communication port 310 can form a rotation path in the rotation process, and since the projection of the center of the air return opening 118 to the direction of the turntable 116 is overlapped with the rotation path of the communication port 310, the communication port 310 and the projection of the air return opening 118 to the direction of the turntable 116 can be at least partially overlapped by controlling the rotation of the turntable 116, so that the communication port 310 is communicated with the air return opening 118 of the temperature-controlled compartment, and the communication state of the air return opening 118 is controlled.

The rotation path is a region formed during the rotation of the communication port 310 about the rotation axis of the turntable 116, that is, the rotation path of the communication port 310 may be a set of arbitrary positions during the rotation of the communication port 310 about the rotation axis of the turntable 116.

For example, the communication port 310 may be a circular hole, and a circular rotation path may be formed when the communication port 310 rotates once in one direction around the rotation axis of the turntable 116. For example, the communication port 310 may be a circular hole, and when the communication port 310 is rotated by a predetermined angle in one direction around the rotational axis of the turntable 116, an arc-shaped rotation path having semicircular ends can be formed. Another example is: the communication port 310 may be a rectangular hole, and a circular rotation path can be formed when the communication port 310 rotates once in one direction around the rotation axis of the turntable 116. For example, the communication port 310 may be a rectangular hole, and when the communication port 310 is rotated by a predetermined angle in one direction around the rotational axis of the turntable 116, an arc-shaped rotational path having both ends at right angles can be formed.

It should be noted that, overlapping means that the positions and shapes of two components or reference figures are identical in space, and overlapping means that at least a part of the intersection exists between the two components or reference figures.

In an embodiment, the communication port 310 and the air return port 118 are circular holes with the same size, the communication port 310 rotates to form a rotation path, and since the projection of the air return port 118 to the direction of the turntable 116 is overlapped with the rotation path of the communication port 310, a state exists, so that the center of the communication port 310 can be overlapped with the projection of the center of the air return port 118 to the direction of the turntable 116, at this time, the air return port 118 and the communication port 310 can completely correspond to each other, the communication port 310 is communicated with the air return port 118 of the temperature control compartment, and thus the temperature of the plurality of temperature control compartments 114 can be better controlled.

By controlling the rotation angle of the turntable 116, the communication port 310 on the turntable 116 can be communicated with the air return port 118 of the temperature-controlled compartment 114 corresponding to the temperature control request, or the communication port 310 on the turntable 116 can be staggered with the air return port 118 of the temperature-controlled compartment 114, so that the air return port 118 closes the communication state of the communication port 310 on the controllable turntable 116 and the air return port 118 of the temperature-controlled compartment 114 requiring temperature control, and therefore, the communication state of the air return ports 118 of the plurality of temperature-controlled compartments 114 can be controlled through the turntable 116, and the temperature of the plurality of temperature-controlled compartments 114 can be controlled.

Further, after the air return opening 118 is closed, the air subsequently entering the temperature-controlled compartment 114 through the air supply opening 117 cannot flow out from the closed air return opening 118, so that the air pressure in the temperature-controlled compartment 114 is higher than the air pressure outside the air return opening 118, and therefore, under the action of the air pressure difference between the air pressure and the air pressure, after the communication opening 310 of the driving device 115 controls the turntable 116 to be communicated with the air return opening 118 and before the air pressure of the air return opening and the air pressure of the air return opening are balanced, the air in the temperature-controlled compartment 114 can quickly flow out from the air return opening 118. Therefore, compared with the conventional method of controlling the temperature of the temperature-controlled compartment 114 through a plurality of air supply dampers, the temperature regulation of the temperature-controlled compartment 114 is more efficient by controlling the opening and closing of the air return opening 118 through the turntable 116 in the present embodiment.

Referring to fig. 1 to 3, the temperature control mechanism of the return air inlet of the above embodiment may be applied to a refrigerating chamber of a refrigerator, the return air temperature control mechanism includes two temperature control compartments 114 arranged adjacently up and down, and a heating device 119 is disposed at the top of the temperature control compartment 114 above. In use, the temperature-controlled compartment 114 provided with the heating device 119 may be set as a high-temperature storage compartment, and the other temperature-controlled compartment 114 may be set as a low-temperature storage compartment.

For example: when the high-temperature storage chamber needs to be heated and the low-temperature storage chamber needs to be refrigerated, the heating device 119 can be started to heat the high-temperature storage chamber, and meanwhile, the communication port 116 and the air return port 118 of the low-temperature storage chamber can be controlled to be communicated for refrigeration, so that the temperature of a plurality of temperature control chambers can be controlled simultaneously, the high-temperature control range of the temperature control chamber 114 is effectively expanded, and the wide temperature regulation of the temperature control chambers is realized.

Another example is: in order to prevent the temperature of the cooling area 111 from being too low, the refrigeration fan 112 of the conventional refrigerator is started or stopped according to the temperature condition of the cooling area 111, that is, the temperature control compartment 114 can only perform synchronous refrigeration with the cooling area 111, and when the temperature of the cooling area 111 reaches a target temperature, the requirement for refrigerating the temperature control compartment 114 cannot be met, and the temperature control of the temperature control compartment 114 is limited by the cooling area 111, so that the temperature control range of the temperature control compartment 114 is narrow. In this case, the heating device 119 may be started in the above scenario, and the heat is transferred to the cold storage region 111 through the sidewall at the top of the high-temperature storage compartment to compensate the temperature of the cold storage region 111, and at this time, the refrigerating fan 112 may be started, and the refrigerating fan 112 may send the cold energy of the refrigerating evaporator 113 into the low-temperature storage compartment through the air channel formed between the air supply opening 117 and the air return opening 118 of the low-temperature storage compartment, so as to prevent the temperature of the cold storage region 111 from being too low and meet the temperature control requirement of the low-temperature storage compartment, effectively expand the low-temperature control range of the temperature control compartment 114, and realize wide temperature adjustment of the temperature control compartment.

It should be noted that the high-temperature storage compartment may be used to store food that needs to be kept at a high temperature, the temperature control range of the high-temperature storage compartment may be set to 8-20 degrees celsius, the low-temperature storage compartment may be used to store food that needs to be kept at a low temperature, and the temperature control range of the low-temperature storage compartment may be set to subzero degrees celsius.

Referring to fig. 2, the return air temperature control mechanism of the above embodiment may cooperate with an operation control device to implement the temperature control operation on the temperature-controlled compartment 114, wherein the operation control device includes a control processor 210 and a memory 220, the control processor 210 and the memory 220 may be connected by a bus, the control processor 210 is electrically connected to the driving device 115 in the return air temperature control mechanism, and the control processor 210 may invoke a return air temperature control program stored in the memory 220, so as to issue a temperature control instruction corresponding to the relevant temperature control request to the driving device 115.

Referring to fig. 4 to 7, the return air temperature control mechanism includes a first temperature-controlled compartment 410 and a second temperature-controlled compartment 420 disposed adjacent to the first temperature-controlled compartment 410, the second temperature-controlled compartment 420 is disposed above the first temperature-controlled compartment 410, the heating device 119 is disposed at the top of the second temperature-controlled compartment 420, the first temperature-controlled compartment 410 includes a first return air opening 411, and the second temperature-controlled compartment 420 includes a second return air opening 421. Because the heating device 119 is disposed at the top of the second temperature-control compartment 420, and the second temperature-control compartment 420 is located above the first temperature-control compartment 410, when the heating device 119 is in operation, the temperature of the second temperature-control compartment 420 can be controlled, and heat is transferred to the outside of the temperature-control compartment 114 through the side wall of the second temperature-control compartment 420, so that the temperature of the second temperature-control compartment 420 can be controlled, and the temperature of the area near the top of the second temperature-control compartment 420 can be compensated.

When the communication port 310 communicates with the second air return opening 421 to cool at the second communication position, if the second temperature-controlled compartment 420 needs to be heated and the first temperature-controlled compartment 410 needs to be cooled, the heating device 119 may start heating, and at the same time, the communication port 310 of the turntable 116 may be controlled to rotate from the second communication position to the first communication position. Wherein the first communication position corresponds to the first air return opening 411, and the second communication position corresponds to the second air return opening 421.

In the above embodiment, the scenario in which the second temperature-control compartment 420 needs to be heated while the second temperature-control compartment 420 is in the process of cooling can be understood as a usage scenario in which the second temperature-control compartment 420 is set from the low-temperature storage temperature region to the high-temperature storage temperature region.

When the communication port 310 communicates with the second air return opening 421 for cooling at the second communication position, if the second temperature-controlled compartment 420 needs to be heated and the first temperature-controlled compartment 410 does not need temperature control, the heating device 119 may start heating, and at the same time, the communication port 310 of the turntable 116 may be controlled to rotate from the second communication position to the first closing position, so that the first air return opening 411 and the second air return opening 421 are in a closed state.

It should be noted that one side of the plurality of temperature-controlled compartments constitutes a compartment outer wall, the turntable 116 is disposed on one side of the compartment outer wall, and a position corresponding to a portion of the compartment outer wall excluding the return air inlet is defined as a first closed position.

In practical applications, the rotating disc 116 may rotate frequently according to a temperature control request, and there is an error in mechanical rotation, where the error is accumulated continuously when there is an error in one rotation, and the error is increased and decreased due to the error, and the setting of the fixed closing position is equivalent to resetting the rotating disc 116, and the error can be cleared.

In another embodiment of the first closing position, the first closing position is a near position, the near position may be a position relatively close to the first communication position and any other two communication positions, and in practical applications, the position relatively close to the first communication position and any other two communication positions may be selected according to the first communication position of the communication port 310, and the communication port 310 is controlled to rotate to the near position, so that the rotating distance of the driving device 115 can be reduced, and the service life of the driving device 115 can be prolonged.

Of course, one skilled in the art can also randomly set the closed position of the communication port 310 of the dial 116. The return air opening 118 can be controlled to be closed by staggering the communication opening 310 and the return air opening 118.

Referring to fig. 8 to 11, the temperature control system includes a first temperature control compartment 410 and a second temperature control compartment 420 disposed adjacent to the first temperature control compartment 410, the second temperature control compartment 420 is horizontally arranged with the first temperature control compartment 410, the first temperature control compartment 410 includes a first air return opening 411, the second temperature control compartment 420 includes a second air return opening 421, and heating devices 119 are disposed on top portions of the first temperature control compartment 410 and the second temperature control compartment 420. When the heating device 119 at the top of two temperature control compartments 114 arranged in the horizontal direction is started, the temperature of the temperature control compartments 114 can be independently controlled without affecting the temperature of the adjacent temperature control compartments.

It should be noted that the heating device 119 may be disposed on top of the first temperature-controlled compartment 410, or on top of the second temperature-controlled compartment 420. The heating device 119 may be disposed on other sides of the temperature-controlled compartment 114 besides the top of the temperature-controlled compartment, and the embodiment of the present invention is not limited thereto.

When both the two temperature control chambers need to be heated and controlled, the heating devices 119 of the two temperature control chambers 114 can be simultaneously opened to meet the heating requirements of the two temperature control chambers 144, and at this time, in order to ensure the heating efficiency of the two temperature control chambers 114, the communication port 310 of the turntable 116 can be controlled to rotate to the first closing position, so that the first air return port 411 and the second air return port 421 are in a closed state.

Note that, when the communication port 310 of the control dial 116 is rotated to the first closing position, the position before the communication port 310 is rotated to the first closing position is not limited, and may be the first communication position or the second communication position.

Referring to fig. 12, in another embodiment of the return air temperature control mechanism of the present invention, the return air temperature control mechanism includes a rectangular temperature control compartment array formed by four temperature control compartments 114, a heating device 119 is disposed on top of two temperature control compartments 114 on the top of the temperature control compartment array, and can implement high temperature storage for the two temperature control compartments 114 on the top, a turntable 116 is disposed on one side of the temperature control compartment array, the turntable 116 is a disk covering return air inlets 118 of the four temperature control compartments 114, and an air supply outlet 117 of the temperature control compartment 114 is disposed on one side of the temperature control compartment array corresponding to the turntable 116, and avoids the coverage of the disk.

For example: the disc is arranged on one side of the temperature control room array in a shape like a Chinese character tian, the projection of the disc can completely fall on one side of the temperature control room array, the position where the disc is arranged can cover the air return openings 118 of the four temperature control rooms 114, one side of the temperature control room array can be enabled to leave a certain area except the coverage area of the projection of the disc by the four temperature control rooms 114, the area can be provided with the air supply opening 117, the structural design can reduce the occupied space of an air return control mechanism, the air return openings 118 and the air supply opening 117 can be arranged on the same side of the temperature control room array, and when the air return temperature control mechanism is applied to a refrigerator, the air duct design can be simplified.

Referring to fig. 1, the return air temperature control mechanism of the present invention is applied to an embodiment of a refrigerator, the refrigerator comprises an evaporator air duct, the evaporator air duct is an air duct in which an evaporator of the refrigerator is located, for providing cold air to the refrigerating chamber 111 or the freezing chamber 121 of the refrigerator, the air return opening 118 of the temperature control compartment 114 can be communicated with the evaporator air duct through the communication opening 310 of the turntable 116, in the present embodiment, the temperature-controlled compartment 114 is disposed in the cooling area, so that the air supply opening 117 of the temperature-controlled compartment 114 and the communication opening 310 of the turntable 116 communicate with the evaporator air duct corresponding to the refrigerating compartment 111, in addition, the rotary plate 116 is arranged close to the evaporator air duct, so that the communication or the sealing between the air return opening 118 and the evaporator air duct can be controlled by the rotary plate 116, the air pressure of the evaporator air duct can be directly utilized to control the temperature of the temperature control compartment 114, and other air supply parts are not required to be added, so that the cost is reduced.

The temperature-controlled compartment 114 may be provided in the freezing zone or in a separate zone. Only the air supply outlet 117 of the temperature control chamber 114 and the communication opening 310 of the turntable 116 need to be communicated with the corresponding evaporator air duct, so that a channel for air circulation can be formed between the air supply outlet 117 and the air return opening 118 of the corresponding temperature control chamber 114, and the temperature of the temperature control chamber 114 can be adjusted.

It should be noted that the evaporator air duct may be a refrigeration evaporator air duct, or other evaporator air ducts. The evaporator may be the refrigerating evaporator 113 installed in the refrigerating evaporator air duct, the freezing evaporator 123 installed in the freezing evaporator air duct, or an evaporator installed in another evaporator air duct.

Further, the evaporator air duct further comprises an air outlet air duct positioned above the evaporator and a return air duct arranged below the evaporator, the air supply outlet 117 of the temperature control compartment 114 is communicated with the air outlet air duct, and the return air inlet 118 of the temperature control compartment 114 is communicated with the return air duct.

Because the air outlet duct above the evaporator can convey cold, the air return duct below the evaporator can convey heat to the evaporator, based on which, the air supply outlet 117 of the temperature control room 114 can be communicated with the air outlet duct, and the air return inlet 118 is communicated with the air return duct, cold is conveyed to the temperature control room 114 through the air supply outlet 117 by using the air pressure of the air outlet duct, and then the heat in the temperature control room 114 is conveyed to the air return duct through the air return inlet 118, so that the temperature of the temperature control room 114 can be controlled by using the air outlet duct above the evaporator.

According to the return air temperature control mechanism in the above embodiment, in practical applications, a plurality of temperature control requests may often occur, and in order for the driving device 115 to normally and orderly control the communication port 310 of the turntable 116 to rotate, so as to meet the temperature control requirements of the plurality of temperature control compartments 114, the plurality of temperature control requests need to be sorted according to the priorities of the temperature control requests, so that the driving device 115 can control the rotation position of the turntable 116 according to the priorities of the temperature control requests.

It should be noted that the priority of the temperature control request includes the following two aspects:

in a first aspect: the temperature control request corresponding to the temperature control room 114 with the temperature difference larger than the threshold value is prioritized, and the temperature difference is the difference between the current temperature of the temperature control room 114 and the preset temperature. When the temperature control device is used, a plurality of temperature control requests occur, and one temperature control request is a temperature control request corresponding to the temperature control chamber 114 with the temperature difference larger than the threshold value, at this time, the food in the temperature control chamber 114 with the temperature difference larger than the threshold value is greatly influenced by the temperature, and the risk of deterioration is easy to occur, the driving device 115 can control the communication port 310 of the turntable 116 to be preferentially communicated with the air return port 118 in the temperature control chamber 114, and preferentially adjust the temperature of the temperature control chamber 114, so that the risk of deterioration of the food is reduced.

In a second aspect: the temperature control request corresponding to the temperature control room 114 having a high priority level is assigned with priority. In actual use, food with higher temperature sensitivity is placed in the temperature control chamber 114 with higher priority, and when the temperature control chamber 114 with higher priority needs temperature control, in order to ensure that the storage of such food is not affected by temperature, the driving device 115 can control the communication port 310 of the turntable 116 to be preferentially communicated with the air return port 118 in the temperature control chamber 114 with higher priority, and preferentially adjust the temperature of the temperature control chamber 114, thereby reducing the risk of food deterioration.

It should be noted that the priority level of the temperature control compartment 114 may be a default setting or may be set by a user, and the invention is not limited thereto.

The embodiment of the invention provides a return air temperature control method, which is applied to an operation control device of a return air temperature control mechanism in the embodiment, wherein the return air temperature control mechanism is described in detail in the embodiment and is not described again. Referring to fig. 13, the return air temperature control method according to the embodiment of the present invention includes the following steps:

s1310: acquiring a first temperature control request for controlling the temperature of a temperature control compartment;

when the temperature of the temperature-controlled compartment does not reach the target temperature, a first temperature-controlled request for controlling the temperature of the temperature-controlled compartment can be acquired, and according to the temperature control condition of the temperature-controlled compartment, the first temperature-controlled request may include: a cooling request, a heating request.

The temperature control chamber is a high-temperature storage chamber, and the temperature of the temperature chamber is lower than the target temperature, so that the first temperature control request is correspondingly a heating request;

the temperature control chamber is a low-temperature storage chamber, the temperature of the temperature control chamber is higher than the target temperature, and the first temperature control request corresponds to a refrigeration request.

The first temperature control request may be a temperature control request of one temperature control room, or may be a set of temperature control requests of a plurality of temperature control rooms.

S1320: and controlling the heating device to start and stop according to the first temperature control request.

The temperature control of the existing temperature control chamber is mainly realized by utilizing a heat exchange mode of air outside the temperature control chamber and air inside the temperature control chamber, and the temperature range which can be controlled by the temperature chamber is narrow due to the limitation of the temperature condition of the air outside the temperature control chamber. According to the embodiment of the invention, the heating device is arranged in at least one temperature control chamber, and the temperature control chamber is a relatively closed independent space, so that the heating device can directly control the temperature of the temperature control chamber, the temperature control requirement range of the temperature control chamber can not be limited by the temperature of air outside the temperature control chamber, when a first temperature control request for controlling the temperature of the temperature control chamber is obtained, the heating device can be controlled to start and stop according to the first temperature control request, and when the heating device heats the temperature control chamber, the temperature change range of the temperature control chamber can be expanded, and wide temperature adjustment of the temperature control chamber is realized.

S1330: and controlling the driving device to drive the turntable to rotate according to the first temperature control request, and controlling the communication state of the air return opening of the temperature control chamber corresponding to the temperature control request.

The temperature control chamber is provided with an air supply outlet and an air return inlet, the temperature control chamber realizes the circulation with the air outside the temperature control chamber through the air supply outlet and the air return inlet, the air outside the temperature control chamber can enter the temperature control chamber from the air supply outlet and flow out from the air return inlet, and in the process, the heat exchange between the inside and the outside of the temperature control chamber can be realized through the flow of the air; and controlling the driving device to drive the turntable to rotate according to the first temperature control request, controlling the communication state of the air return opening of the temperature control chamber corresponding to the temperature control request, and forming a channel for air circulation between the air supply opening and the air return opening of the corresponding temperature control chamber, thereby realizing the temperature regulation of the temperature control chamber.

By controlling the rotation angle of the turntable, the communication port on the turntable can be communicated with the air return port of the temperature control chamber, and the communication port on the turntable can also be staggered with the air return port of the temperature control chamber, so that the air return port is closed.

The communicating port on the control turntable can be controlled to be communicated with the air return ports of the temperature control rooms with required temperature control, so that the communicating state of the air return ports of the temperature control rooms can be controlled through the turntable, and the temperature of the temperature control rooms can be controlled.

The heating device is controlled to heat according to the first temperature control request, and the communication port of the control drive device for driving the turntable is not communicated with the return air port of the temperature control chamber for heating. In order to effectively improve the heating efficiency of the temperature control chamber, the driving device can be controlled to drive the rotary disc to seal the air return opening of the heated temperature control chamber according to the first temperature control request, and the air circulation channel between the air supply opening and the air return opening can be interrupted, so that the heat loss of the temperature control chamber is prevented.

It should be noted that, because the current position of the communication port may be determined according to the prior control, when different temperature control requests are obtained, the driving device needs to be controlled to drive the communication port of the turntable to rotate according to the start-stop condition of the heating device, the current position condition of the communication port, and the temperature control request, so as to control the communication state of the return air inlet of the temperature control compartment corresponding to the temperature control request.

For example: the return air temperature control mechanism comprises a first temperature control room and a second temperature control room which is adjacently arranged in the first temperature control room, the second temperature control room is positioned on the first temperature control room, the heating device is arranged at the top of the second temperature control room, the first temperature control room comprises a first return air inlet, the second temperature control room comprises a second return air inlet, the heating device heats according to a first temperature control request, the driving device is controlled to drive the rotating disc to rotate according to the first temperature control request, and the step of controlling the communication state of the return air inlet of the temperature control room corresponding to the temperature control request can comprise the following four aspects:

in a first aspect: when the communication port is located at the second communication position, acquiring a temperature control request of the first temperature control chamber, confirming the temperature control request of the first temperature control chamber as the first temperature control request, and controlling the communication port of the turntable to rotate from the second communication position to the first communication position according to the first temperature control request, wherein the first communication position corresponds to the first air return port, and the second communication position corresponds to the second air return port;
