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.
It should be noted that, after the air return opening is closed, the air subsequently entering the temperature control chamber through the air supply opening cannot flow out from the closed air return opening, so that the air pressure in the temperature control chamber is higher than the air pressure outside the air return opening, and therefore, under the action of the air pressure difference between the air return opening and the air return opening, after the communication opening of the driving device controlling the turntable is communicated with the air return opening, and before the air pressure of the communication opening and the air return opening is balanced, the air in the temperature control chamber can flow out from the air return opening rapidly, so that the temperature regulation efficiency of the temperature control chamber can be improved.

The embodiments of the present invention will be further explained with reference to the drawings.
The return air temperature control mechanism provided by an embodiment of the invention is applied to a refrigerator shown in fig. 1 and fig. 2, the refrigerator comprises a refrigerating chamber 110 and a freezing chamber 120, the refrigerating chamber 110 comprises a refrigerating area 111, a refrigerating evaporator air duct, a refrigerating fan 112, a refrigerating evaporator 113, at least two temperature control chambers 114, a driving device 115 and a turntable 116, the refrigerating fan 112 and the refrigerating evaporator 113 are arranged in the refrigerating evaporator air duct, the temperature control chambers 114 are arranged in the refrigerating area 111, each temperature control chamber comprises an air supply opening 117 and an air return opening 118, an air supply control part 119 is arranged on the air supply opening 117, the temperature control chambers 114 are communicated with the refrigerating evaporator air duct through the air supply openings 117 and the air return openings 118, the turntable 116 is arranged between the air return openings 118 and the refrigerating evaporator air duct, the driving device 115 is connected with the turntable 116, the freezing chamber 120 comprises a freezing area 121, a freezing fan 122, a freezing evaporator 123 and a freezing evaporator air duct, the freezing evaporator 123 and the freezing fan 122 are disposed in the freezing evaporator air duct.
Referring to fig. 3 and 4, the return air temperature control mechanism according to the embodiment of the present invention includes a turntable 116, a driving device 115 for controlling the rotation of the turntable 116, and at least two temperature control compartments 114, where each temperature control compartment 114 includes an air supply opening 117 and an air return opening 118, and the turntable 116 is provided with a communication opening 410 capable of corresponding to the air return opening 118.
It should be noted that the return air temperature control mechanism is not limited to be used in the refrigerating chamber of the refrigerator, but may be used in the freezing chamber or other chambers of the refrigerator.
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 of the air outside the temperature-controlled compartment 114 through the air supply outlet 117 and the air return outlet 118, and 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 under the control of the air supply control part 119, 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 passage, 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 port 410 on the turntable 116, and based on the result, the driving device 115 controls the turntable 116 to rotate according to the temperature control request, so that the communication port 410 is communicated with the air return outlet 118 of the temperature-controlled compartment 114 corresponding to the temperature control request, a channel for air circulation is formed between the air supply outlet 117 and the air return outlet 118 of the corresponding temperature control compartment 114, thereby realizing the temperature regulation of the temperature control compartment 114. Note that the temperature control request is used to control the temperature of the temperature control compartment 114.
Further, in the embodiment of the present invention, the communication port 410 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 410 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 410, the communication port 410 may be in a fan shape, a square shape, a circular shape or other irregular shapes, and the area of the communication port 410 is not limited, and the area of the communication port 410 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 410 and the air return opening 118 have the same shape, but the area of the communication port 410 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 410, 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 410 and the air return opening 118 can be set to be the same, and when the communication port 410 and the air return opening 118 are controlled to be communicated, since the shape and the size of the communication port 410 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 410 provided on the turntable 116 may be one or more than two, and when the number of the communication ports 410 provided on the turntable 116 is one, the communication ports 410 can be controlled to be communicated with the air return ports 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 410 can be provided, and the communication ports 410 are used for simultaneously controlling the communication state of the air return ports 118 of the two or more 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 continuous return air opening 118 in the direction of the turntable 116 overlaps with the rotation path of the communication opening 410. When the turntable 116 rotates, the communication port 410 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 410, the communication port 410 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 410 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 410 around the rotation axis of the turntable 116, that is, the rotation path of the communication port 410 may be a set of arbitrary positions during the rotation of the communication port 410 around the rotation axis of the turntable 116.
For example, the communication port 410 may be a circular hole, and a circular rotation path can be formed when the communication port 410 rotates once in one direction around the rotation axis of the turntable 116. For example, the communication port 410 may be a circular hole, and when the communication port 410 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 opening 410 may be a rectangular hole, and a circular rotation path can be formed when the communication opening 410 rotates once in one direction around the rotation axis of the turntable 116. For example, the communication port 410 may be a rectangular hole, and when the communication port 410 is rotated by a certain 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 410 and the air return port 118 are circular holes with the same size, the communication port 410 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 410, a state exists, so that the center of the communication port 410 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 410 can completely correspond to each other, the communication port 410 is communicated with the air return port 118 of the temperature-control compartment, and thus the temperature of the temperature-control compartments 114 can be better controlled.
Further, by controlling the rotation angle of the turntable 116, the communication port 410 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, and the communication port 410 on the turntable 116 can also be dislocated from 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 410 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 temperature-controlled compartments 114 can be controlled through the turntable 116, and the temperature of the temperature-controlled compartments 114 can be controlled.
Illustratively, the supply air control component 119 may include a supply air damper or a supply air fan. Referring to fig. 1, when air supply control unit 119 includes an air supply damper, the air supply damper is opened and closed in response to a temperature control request. The opening and closing of the air supply damper is used for controlling the air supply of the air supply outlet 117, when the air supply damper is closed, the air supply outlet 117 is also closed, and at the moment, the air supply outlet 117 stops supplying air; when the supply damper is opened, the supply port 117 is also opened, and the supply port 117 starts supplying air. The air supply damper can be mounted on the air supply outlet 117 in a hinged manner, and the rotation of the air supply damper is controlled by a servo motor or a stepping motor so as to achieve the opening and closing effect of the air supply outlet 117; alternatively, the air supply damper may be folded, and the guide rail drives the air supply damper to slide, so as to achieve the opening and closing effect of the air supply opening 117. The temperature of the temperature control chamber 114 is adjusted by arranging the air supply air door, opening and closing the air supply air door according to the temperature control request and simultaneously opening the air return port 118 when the air supply air door is opened; and the air supply damper closes the air return opening 118 when being closed, so that the effect of keeping the temperature of the temperature control compartment 114 can be achieved.
Referring to fig. 2, when the air supply control part 119 includes an air supply fan, the air supply fan is turned on and off according to a temperature control request. The start and stop of the air supply fan is used for controlling whether the air supply port 117 supplies air or not, and when the air supply fan is closed, the air supply port 117 stops supplying air; when the blower fan is activated, air flows from the blower port 117 into the temperature-controlled compartment 114 by the blower fan. The air supply fan can adopt a fan blade structure to generate air supply power, and can also adopt an air multiplier similar to a bladeless fan in the prior art to generate air supply power. The temperature of the temperature control chamber 114 is adjusted by arranging the air supply fan, starting and stopping the air supply fan according to the temperature control request, and simultaneously opening the air return port 118 when the air supply fan is started; and the air supply fan closes the air return opening 118 when being closed, so that the effect of temperature maintenance of the temperature control chamber 114 can be achieved.
It can be understood that, since the air supply fan has a gap, when the air supply fan stops operating, a small portion of air enters the temperature-controlled compartment 114 from the air supply opening 117, and on this basis, 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 410 of the turntable 116 is controlled by the driving device 115 to communicate with the air return opening 118, and before the air pressure of the two is balanced, the air in the temperature-controlled compartment 114 can flow out from the air return opening 118 quickly. 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.
And when the air supply control component comprises an air supply fan, the air supply direction can be changed according to the temperature control request. The air supply fan can generate air supply power to enable the air supply opening to start air inlet, airflow enters the temperature control chamber from the air supply opening, and meanwhile the air supply fan can also generate opposite power to enable the airflow not to enter the temperature control chamber from the air supply opening, namely the flowing direction of the air is opposite to that when the air supply opening starts air inlet. Exemplarily, when the air supply fan adopts a fan blade structure to generate air supply power, the air flow direction of the air supply outlet can be controlled by controlling the motor of the air supply fan to rotate forwards or backwards; or the whole air supply fan is rotated by 180 degrees, so that the wind direction of the air supply fan is changed; when the air supply fan realizes air supply by using the air multiplier, the air multiplier is also driven by using the motor, and the air flowing direction of the air supply outlet can be controlled by controlling the motor of the air supply fan to rotate forwards or backwards. When the return air inlet is changed from opening to closing, the air supply fan changes the air direction of air supply, so that air can not enter the temperature control chamber through the air supply outlet, and the temperature control chamber is favorable for improving the temperature keeping effect of the temperature control chamber compared with the air supply fan which is closed.
Referring to fig. 3, the return air temperature control mechanism of the above embodiment may cooperate with an operation control device to implement the temperature control operation of the temperature controlled compartment 114, wherein the operation control device includes a control processor 310 and a memory 320, the control processor 310 and the memory 320 may be connected by a bus, the control processor 310 is electrically connected to the driving device 115 and the air supply control component 119 in the return air temperature control mechanism, and the control processor 310 may call a return air temperature control program stored in the memory 320, so as to issue a temperature control instruction corresponding to the relevant temperature control request to the driving device 115 and the air supply control component 119.
Referring to fig. 5 to 12, the return air temperature control mechanism includes a first temperature-controlled compartment 510 and a second temperature-controlled compartment 520, the first temperature-controlled compartment 510 includes a first return air opening 511 and a first air supply control member 512, the second temperature-controlled compartment 520 includes a second return air opening 521 and a second air supply control member 522, the driving device 115 controls the communication opening 410 of the turntable 116 to rotate to a second communication position according to a temperature control request, the first air supply control member 512 stops air supply from the air supply opening 117 of the first temperature-controlled compartment 510 according to the temperature control request, the second air supply control member 522 starts air supply from the air supply opening 117 of the second temperature-controlled compartment 520 according to the temperature control request, the first communication position corresponds to the first return air opening 511, and the second communication position corresponds to the second return air opening 521.
If the second temperature-control compartment 520 needs temperature control, the driving device 115 may control the communication port 410 of the turntable 116 to rotate from the first communication position to the second communication position according to a temperature control request, so that the communication port 410 of the second temperature-control compartment 520 is communicated with the second air return port 521, meanwhile, the air supply port 117 of the first temperature-control compartment 510 stops supplying air, the air supply port 117 of the second temperature-control compartment 520 starts supplying air, so as to realize temperature control of the second temperature-control compartment 520. The communication port 410 is rotated to the second communication position from the first communication position to the second communication position, or from the first closed position to the second communication position.
Wherein the first communication position corresponds to the first air return opening 511; and one side of the plurality of temperature-controlled compartments constitutes a compartment outer wall, and the turntable 116 is disposed at one side of the compartment outer wall, and defines a position corresponding to a portion of the compartment outer wall excluding the return air inlet 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 410, and the communication port 410 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 410 of the dial 116. The return air opening 118 can be controlled to be closed by staggering the communication opening 410 and the return air opening 118.
It should be noted that a first setting condition may be further provided, in which the communication port 410 may be maintained at the first communication position, after the first setting condition is reached, the driving device 115 controls the communication port 410 of the turntable 116 to rotate from the first communication position to the second communication position again, the first air blowing control component 512 stops air feeding from the air blowing port 117 of the first temperature-controlled compartment 510 according to the temperature control request, and the second air blowing control component 522 starts air feeding from the air blowing port 117 of the second temperature-controlled compartment 520 according to the temperature control request, thereby effectively solving the problem that the temperature control in one of the temperature-controlled compartments 114 is not satisfied due to a too short time interval of the temperature control requirements of the two temperature-controlled compartments 114.
When the air supply control part 119 is an air supply damper, the air supply state of the air supply port 117 can be changed by opening or closing; when the air supply control part 119 is an air supply fan, the air supply state of the air supply port 117 may be changed by turning on or off, or the air supply state of the air supply port 117 may be changed by changing the air supply direction of the air supply fan. Illustratively, the first air supply control part 512 stops the air supply from the air supply port 117 of the first temperature-controlled compartment 510 according to the temperature control request, and may close an air supply damper according to the temperature control request, or close an air supply fan according to the temperature control request, or supply air to the outside of the first temperature-controlled compartment 510 according to the temperature control request; the second air supply control unit 522 may start air supply from the air supply port 117 of the second temperature-controlled compartment 520 in response to a temperature control request, open an air supply damper in response to a temperature control request, or supply air to the inside of the second temperature-controlled compartment 520 by an air supply fan in response to a temperature control request.
In one embodiment, the first set condition may be that the temperature of the first temperature-controlled compartment 510 reaches a first target temperature.
For example: when a plurality of temperature-controlled compartments 114 need to be temperature-controlled, the communication port 410 can be maintained at the first communication position, after the temperature of the first temperature-controlled compartment 510 reaches the first target temperature, the driving device 115 controls the communication port 410 of the turntable 116 to rotate from the first communication position to the second communication position again, the first air supply control component 512 stops the air supply to the air supply port 117 of the first temperature-controlled compartment 510 according to the temperature control request, the second air supply control component 522 starts the air supply to the air supply port 117 of the second temperature-controlled compartment 520 according to the temperature control request, and the communication port 410 can be maintained at the second communication position until the temperature of the second temperature-controlled compartment 520 reaches the second target temperature, that is, the driving device 115 and the air supply control component 119 can sequentially manage the temperatures of the plurality of temperature-controlled compartments 114 according to the set conditions, thereby controlling the temperatures of the plurality of temperature-controlled compartments 114.

In actual use, food with higher temperature sensitivity is placed in the temperature control chamber 114 with higher priority, 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 410 of the turntable 116 to be communicated with the air return port 118 in the temperature control chamber 114 with higher priority, and simultaneously the air supply control part 119 controls the corresponding air supply port 117 to start air supply, so as to adjust the temperature of the temperature control chamber 114 preferentially, 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.
