Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a refrigerator, a control method, a control device and a storage medium. Background Art

[0002] At present, air-cooled refrigerators use fans to force air convection to bring the cold energy generated by the evaporator into the storage compartment for refrigeration. Most refrigerators in the related art use the back-to-back air outlet method, that is, the wind blows from the rear end of the compartment to the front end of the compartment. When there are many items stored inside the refrigerator, the air volume in the front area of ​​the compartment is small, resulting in a large temperature difference between the front and rear ends of the refrigerator, affecting the refrigeration effect of the refrigerator. At the same time, the return air of each compartment in the air-cooled refrigerator of the related art needs to pass through the same air inlet to reach the bottom of the evaporator, and the humidity of compartments with different temperatures is different. When the return air of each compartment meets at the bottom of the evaporator, the evaporator will frost quickly. Frequent operation of the heater to defrost the evaporator not only increases the energy consumption of the refrigerator, but also reduces the refrigeration effect of the refrigerator. Therefore, how to improve the refrigeration effect of the refrigerator while reducing the energy consumption of the refrigerator has become an urgent problem to be solved. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a refrigerator, a control method, a control device and a storage medium, which can effectively improve the refrigeration effect of the refrigerator and reduce the energy consumption of the refrigerator.

[0004] In a first aspect, an embodiment of the present invention provides a method for controlling a refrigerator, the method comprising:

[0005] A box body, provided with a first partition for separating a refrigerating chamber and a freezing chamber in the box body;

[0006] An air duct assembly is arranged in the first partition, the air duct assembly includes an air duct housing having a first heat exchange cavity and a second heat exchange cavity, the air duct housing is provided with a first air outlet, a first air return outlet, and a second air outlet communicating with the first heat exchange cavity, and a second air return outlet communicating with the second heat exchange cavity, the first heat exchange cavity and the second heat exchange cavity are connected, and the first heat exchange cavity is located above the second heat exchange cavity, the first air outlet and the first air return outlet are respectively communicated with the refrigerating chamber, and the second air outlet and the second air return outlet are respectively communicated with the freezing chamber;

[0007] A first evaporator, disposed in the first heat exchange chamber;

[0008] A second evaporator is disposed in the second heat exchange cavity;

[0009] a first heater, disposed on one side of the first evaporator, for defrosting the first evaporator;

[0010] The second heater is arranged at one side of the second evaporator and is used for defrosting the second evaporator.

[0011] The refrigerator provided according to the embodiment of the present invention has at least the following beneficial effects: the air duct assembly, multiple evaporators and multiple heaters are arranged in the first partition of the box body, wherein the cold air of the first heat exchange cavity in the air duct housing is transported to the refrigerating chamber through the first air outlet, and the cold air enters the first heat exchange cavity through the first return air outlet for heat exchange. The cold air in the freezing chamber enters the second heat exchange cavity through the second return air outlet for primary heat exchange, and then enters the first heat exchange cavity for secondary heat exchange. The cold air after the secondary heat exchange is transported to the freezing chamber through the second air outlet. Thus, the return air of the freezing chamber and the return air of the refrigerating chamber enter the air duct housing through different return air outlets for heat exchange, so that the return air of different compartments cannot meet at the same time, avoiding the frequent frosting of the evaporator, and then there is no need to frequently run the heater for defrosting. At the same time, using corresponding heaters for independent defrosting for different evaporators can improve the defrosting efficiency, save frost energy consumption, and improve the refrigeration effect. At the same time, since the air duct components, multiple evaporators and multiple heaters do not need to occupy the back space of the refrigerator body, the internal depth of the body can be increased, the effective storage space can be increased, and the effect of air outlet at the sides of each compartment can be achieved, thereby solving the problem of small air volume and uneven temperature in the front end area of ​​the compartment of the box, and improving the refrigeration effect of the refrigerator.

[0012] In the above-mentioned refrigerator, the air duct shell is provided with a first air duct component and a second air duct component, the first air outlet is located in the first air duct component, and the first air outlet is connected with the first heat exchange cavity through the first air duct component; the second air outlet is located in the second air duct component, and the second air outlet is connected with the first heat exchange cavity through the second air duct component.

[0013] Using the first air duct component to supply air to the refrigerating chamber alone, and using the second air duct component to discharge air to the freezing chamber alone, can help control the air volume of each compartment and achieve accurate temperature control.

[0014] In the above refrigerator, the first air duct component and the second air duct component are respectively arranged on the top of the air duct shell along the length direction of the air duct shell, and the first air duct component and the second air duct component are respectively extended along the height direction of the air duct shell.

[0015] The first air duct component and the second air duct component are arranged on the top of the air duct housing, which can effectively reduce the thickness of the first partition, help to place the first partition in the refrigerator body, and save the internal space of the box. At the same time, the first air duct component and the second air duct component extend along the height direction of the first partition respectively, so that multiple air outlets can be set, which helps to increase the air output and improve the air supply efficiency.

[0016] In the above refrigerator, a first damper for controlling the on / off state of the first air duct component is arranged between the first air duct component and the first heat exchange chamber.

[0017] By adjusting the first air gate, it is possible to control whether the first air duct component is connected to the first heat exchange chamber, thereby controlling the cold air to enter the first air duct component and supply air to the refrigerating chamber through the first air duct component. Therefore, the first air gate can be used to control the temperature and air volume of the refrigerating chamber.

[0018] In the above-mentioned refrigerator, a variable temperature chamber is also provided in the box body, and the variable temperature chamber is located below the refrigerating chamber. The air duct shell is also provided with a third air outlet connected to the first heat exchange chamber, and a third return air outlet connected to the second heat exchange chamber. The third air outlet and the third return air outlet are respectively connected to the variable temperature chamber, and the third return air outlet is located on the side wall of the variable temperature chamber.

[0019] By setting a variable temperature chamber in the box body and setting a third air outlet and a third return air outlet in the air duct shell, the third return air outlet is located on the side wall of the variable temperature chamber, so that the cold air of each compartment can enter the air duct shell from different return air outlets, reducing the occurrence of frosting and improving the refrigeration effect.

[0020] In the above-mentioned refrigerator, the air duct shell is also provided with a third air duct component, a second partition is provided between the refrigeration chamber and the temperature changing chamber, the third air duct component is arranged on the second partition, the third air outlet is located in the third air duct component, and the third air outlet is connected with the first heat exchange chamber through the third air duct component.

[0021] The cold storage room and the variable temperature room are separated by a second partition, and a third air outlet is provided on the third air duct component, so that air can be supplied to the variable temperature room independently. Meanwhile, the third air duct component is arranged in the second partition, which can save space in the variable temperature room.

[0022] In the above refrigerator, a second air door for controlling the on / off state of the third air duct component is provided between the third air duct component and the first heat exchange chamber.

[0023] By adjusting the second air door, it is possible to control whether the third air duct component is connected to the first heat exchange chamber, thereby controlling the amount of air entering the temperature changing chamber and accurately controlling the temperature of the temperature changing chamber.

[0024] In a second aspect, an embodiment of the present invention provides a refrigerator control method, which is applied to the refrigerator according to the embodiment of the first aspect, and the control method includes:

[0025] Acquiring a first operating parameter of the first evaporator and a second operating parameter of the second evaporator;

[0026] In response to the first operating parameter and / or the second operating parameter satisfying a preset defrosting condition, the first heater and the second heater are controlled to independently defrost the first evaporator and the second evaporator, respectively.

[0027] The control method provided by the embodiment of the present invention has at least the following beneficial effects: through the first working parameter of the first evaporator and the second working parameter of the second evaporator, it is respectively judged whether the first evaporator and the second evaporator need to operate the heater for defrosting, so as to avoid running the heater for a long time to increase energy consumption and affect the heat exchange efficiency. When the first working parameter and / or the second working parameter meet the preset defrosting conditions, it can be considered that the first evaporator and / or the second evaporator have the risk of frosting, then the corresponding heater is controlled to operate independently, and the corresponding evaporator is independently heated for defrosting, which can shorten the defrosting time, improve the defrosting efficiency, and reduce the defrosting energy consumption.

[0028] In the above-mentioned control method, the preset defrost condition is that the first working parameter reaches the first defrost cycle, or the second working parameter reaches the second defrost cycle; wherein, the first working parameter is characterized by the operating time of the first evaporator; the second working parameter is characterized by the operating time of the second evaporator; the first defrost cycle and the second defrost cycle are the same or different.

[0029] Whether the first heater and the second heater have a risk of frosting is determined by the respective operating time of the first heater and the second heater. When the operating time of the evaporator reaches the corresponding defrosting cycle, it can be considered that the evaporator has a risk of frosting, and it is necessary to operate the corresponding heater for separate defrosting, shorten the defrosting time, and improve the defrosting efficiency.

[0030] In the above control method, in response to the first operating parameter satisfying a preset defrosting condition, the first heater is controlled to operate within a first defrosting time period;

[0031] or,

[0032] In response to the second operating parameter satisfying a preset defrosting condition, controlling the second heater to operate within a second defrosting time period;

[0033] The first defrost time and the second defrost time are the same or different.

[0034] When there is a risk of frost on the first evaporator, the first heater is controlled to heat and defrost the first evaporator alone, and the operation is performed for a first defrost duration. When there is a risk of frost on the second evaporator, the second heater is controlled to heat and defrost the second evaporator alone for a second defrost duration. Different evaporators are defrosted independently using different heaters, and the corresponding heaters are controlled to operate for corresponding heating and defrosting durations according to different evaporators, thereby achieving the effect of improving defrost efficiency.

[0035] In a third aspect, an embodiment of the present invention provides an operation control device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the control method described in the embodiment of the first aspect when executing the computer program.

[0036] The operation control device provided by the embodiment of the present invention has at least the following beneficial effects: the operation control device can judge whether the first evaporator and the second evaporator need to run the heater for defrosting respectively through the first working parameter of the first evaporator and the second working parameter of the second evaporator, so as to avoid running the heater for a long time to increase energy consumption and affect the heat exchange efficiency. When the first working parameter and / or the second working parameter meet the preset defrosting conditions, it can be considered that the first evaporator and / or the second evaporator have the risk of frosting, then the corresponding heater is controlled to run independently, and the corresponding evaporator is independently heated for defrosting, which can shorten the defrosting time, improve the defrosting efficiency, and reduce the defrosting energy consumption.

[0037] In a fourth aspect, an embodiment of the present invention provides a computer-readable storage medium, wherein the computer-readable storage medium stores computer-executable instructions, and the computer-executable instructions are used to enable a computer to execute the control method described in the embodiment of the first aspect above.

[0038] The computer-readable storage medium provided by the embodiment of the present invention has at least the following beneficial effects: using the first operating parameter of the first evaporator and the second operating parameter of the second evaporator to respectively determine whether the first evaporator and the second evaporator need to operate the heater for defrosting, thereby avoiding long-term operation of the heater to increase energy consumption and affect heat exchange efficiency. When the first operating parameter and / or the second operating parameter meet the preset defrosting conditions, it can be considered that the first evaporator and / or the second evaporator have a risk of frosting, then the corresponding heater is controlled to operate independently, and the corresponding evaporator is independently heated for defrosting, which can shorten the defrosting time, improve the defrosting efficiency, and reduce the defrosting energy consumption.

It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that in the flowchart.

[0059] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0060] The embodiment of the present invention provides a refrigerator and a control method, device and storage medium thereof. An air duct assembly, multiple evaporators and multiple heaters are arranged in a first partition of a box body, so that the box body is divided into a refrigerating chamber and a freezing chamber. A first air outlet, a first return air outlet, a second air outlet and a second return air outlet are arranged on the air duct assembly, so that the return air of the freezing chamber and the return air of the refrigerating chamber enter the air duct shell through different return air outlets for heat exchange, so that the return air of different chambers cannot meet at the same time, and the frequent frosting of the evaporator is avoided, and there is no need to frequently operate the heater for defrosting. At the same time, the first working parameter of the first evaporator and the second working parameter of the second evaporator are used to judge whether the first evaporator and the second evaporator need to operate the heater for defrosting respectively. Corresponding heaters are used for independent defrosting of different evaporators, which can improve the defrosting efficiency, save frost energy consumption and improve the refrigeration effect. At the same time, since the air duct components, multiple evaporators and multiple heaters do not need to occupy the back space of the refrigerator body, the internal depth of the body can be increased, the effective storage space can be increased, and the effect of air outlet at the sides of each compartment can be achieved, thereby solving the problem of small air volume and uneven temperature in the front end area of ​​the compartment of the box, and improving the refrigeration effect of the refrigerator.

[0061] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0062] First, refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of a refrigerator 100 provided in an embodiment of the present invention. Figure 2 yes Figure 1 It is understood that the refrigerator 100 includes a box body 110, and a first partition 111 is arranged inside the box body 110, and the first partition 111 divides the inner cavity of the box body 110 into a refrigerating chamber 112 and a freezing chamber 113. In an embodiment, the first partition 111 can be vertically arranged inside the box body 110, that is, the inner cavity of the box body 110 is divided into left and right sides, and the refrigerating chamber 112 is located on the right side of the box body 110, and the freezing chamber 113 is located on the left side of the box body 110.

[0063] The cabinet 110 may include a refrigerator compartment 112 door for opening and closing the refrigerator compartment 112, and a freezer compartment 113 door for opening and closing the freezer compartment 113. The refrigerator compartment 112 door and the freezer compartment 113 door may be hingedly coupled to the front of the cabinet 110 so that the refrigerator compartment 112 door may be rotated to open or close the refrigerator compartment 112, and the freezer compartment 113 door may be rotated to open or close the freezer compartment 113.

[0064] refer to Figure 3 , Figure 31 is a partial structural diagram of a refrigerator 100 provided in an embodiment of the present invention. It is understandable that the refrigerator 100 further includes an air duct assembly 120, a first evaporator 140, a second evaporator 150, a first heater 160 and a second heater 170. The air duct assembly 120 is installed in the first partition 111, and the first evaporator 140, the second evaporator 150, the first heater 160 and the second heater 170 are all installed on the air duct assembly 120.

[0065] The air duct assembly 120 includes an air duct housing 123, and the air duct housing 123 has a first heat exchange chamber 121 and a second heat exchange chamber 122. The first evaporator 140 and the first heater 160 are installed in the first heat exchange chamber 121, and the second evaporator 150 and the second heater 170 are installed in the second heat exchange chamber 122. Among them, the first evaporator 140 and the second evaporator 150 can be connected, that is, the refrigerant between the first evaporator 140 and the second evaporator 150 can flow mutually, or they can be independently set, that is, the refrigerant between the first evaporator 140 and the second evaporator 150 cannot flow. The first evaporator 140 and the second evaporator 150 are set in series, and the working states of the first evaporator 140 and the second evaporator 150 are synchronized, that is, the two evaporators are turned on or off at the same time.

[0066] The side wall of the air duct housing 123 is provided with a first air outlet 124 , a second air outlet 126 , a first air return outlet 125 and a second air return outlet 127 . Among them, a fan is also provided in the air duct shell 123, and the fan is installed in the first heat exchange chamber 121 and is close to the first air outlet 124 and the second air outlet 126, and the first air outlet 124, the second air outlet 126 and the first return air outlet 125 are respectively connected to the first heat exchange chamber 121, and the first air outlet 124 and the first return air outlet 125 are respectively connected to the refrigerating chamber 112, that is, driven by the fan, the cold air of the refrigerating chamber 112 enters the first heat exchange chamber 121 in the air duct shell 123 through the first return air outlet 125, and the first evaporator 140 arranged in the first heat exchange chamber 121 exchanges heat for the return air, and the cold air after heat exchange and cooling is transported to the refrigerating chamber 112 through the first air outlet 124, thereby realizing the circulating refrigeration of the refrigerating chamber 112.

[0067] The second air outlet 126 is in communication with the second heat exchange cavity 122, which is in communication with the first heat exchange cavity 121. The second air outlet 126 and the second return air outlet 127 are respectively in communication with the freezing chamber 113. Therefore, the cold air of the freezing chamber 113 enters the second heat exchange cavity 122 in the air duct housing 123 through the second return air outlet 127, and the second evaporator 150 provided in the second heat exchange cavity 122 exchanges heat with the return air of the freezing chamber 113. Since the cold air temperature required by the freezing chamber 113 is lower than the cold air required by the refrigerating chamber 112, the cold air after cooling enters the first heat exchange cavity 121 for secondary heat exchange, and the second heat exchange cavity 122 is located below the first heat exchange cavity 121, so that the cold air can fully exchange heat in the first heat exchange cavity 121, and the cold air after secondary heat exchange and cooling is transported to the freezing chamber 113 through the second air outlet 126, so as to realize the circulating refrigeration of the freezing chamber 113.

[0068] In addition, the first evaporator 140 is used to heat the gas in the first heat exchange chamber 121, which is equivalent to the first evaporator 140 exchanging heat with the return air of the refrigerating chamber 112 and the cold air after heat exchange in the second heat exchange chamber 122. The second evaporator 150 is used to heat the gas in the second heat exchange chamber 122, which is equivalent to the second evaporator 150 only needing to heat the return air of the freezing chamber 113, that is, the heat exchange amount required by the first evaporator 140 and the second evaporator 150 may be different, and the frost risk of the first evaporator 140 may be different from the frost risk of the second evaporator 150.

[0069] Therefore, corresponding heaters are respectively provided for the first evaporator 140 and the second evaporator 150 for heating and defrosting, and separate defrosting can be performed according to the frost risk of the corresponding evaporator, that is, a first heater 160 is provided on one side of the first evaporator 140, and the first heater 160 is only used for heating and defrosting the first evaporator 140, while a second heater 170 is provided on one side of the second evaporator 150, and the second heater 170 is only used for heating and defrosting the second evaporator 150. Different evaporators can be heated and defrosted independently without interfering with each other, which can improve the defrosting efficiency and shorten the defrosting time, thereby reducing the defrosting energy consumption and improving the refrigeration efficiency.

[0070] Among them, the side walls on both sides of the first partition 111 are respectively provided with through holes corresponding to the first air outlet 124, the first return air outlet 125, the second air outlet 126 and the second return air outlet 127. The first air outlet 124 and the first return air outlet 125 are located on the side wall of the first partition 111 facing the refrigerating chamber 112. At the same time, the second air outlet 126 and the second return air outlet 127 are located on the other side wall of the first partition 111 facing the freezing chamber 113, so that side air outlet of the refrigerating chamber 112 and the freezing chamber 113 can be achieved. Compared with the air-cooled refrigerator 100 that adopts the rear-end air outlet method in the related art, that is, the solution in which the freezing air supply component and the refrigerating chamber 112 air supply component are arranged at the rear end of the box body 110, the air supply component occupies the rear end space of the box body 110, affecting the depth of the drawer and further affecting the effective storage space. At the same time, since the cold air blows from the rear end to the front end of the box body 110, when more food is stored, the air volume at the front end of the box body 110 is small, the temperature distribution in the same room is uneven, and the temperature in the front area is high, which is not conducive to food preservation.

[0071] In the embodiment of the present invention, the air duct assembly 120, multiple evaporators and multiple heaters are all arranged in the first partition 111, without occupying the rear end space of the box body 110, which can increase the internal depth of the box body 110, increase the effective storage space, and achieve the effect of air outlet from the side of each compartment, thereby solving the problem of uneven temperature caused by small air volume in the front end area of ​​the compartment of the box body 110, and improving the refrigeration effect and preservation effect of the refrigerator 100. At the same time, since the temperature of the freezing chamber 113 is lower than that of the cold storage chamber 112, the humidity of the freezing chamber 113 is also lower than that of the cold storage chamber 112. When gases with different humidity and temperature meet at the evaporator at the same time, it is easy to cause the evaporator to frost quickly, so that the heater needs to be frequently operated to heat and defrost, which affects the energy consumption of the refrigerator 100 and also reduces the refrigeration efficiency of the refrigerator 100.

[0072] However, in the embodiment of the present invention, the positions of the first return air inlet 125 and the second return air inlet 127 are different, and the first return air inlet 125 is connected to the first heat exchange chamber 121, and the second return air inlet 127 is connected to the second heat exchange chamber 122. Therefore, the return air of the freezer chamber 113 and the return air of the refrigerator chamber 112 cannot meet at the same time, thereby avoiding frequent frosting of the evaporator and increasing the frosting interval of the evaporator. There is no need to frequently operate the heater for defrosting, which correspondingly increases the working interval of the heater, thereby reducing the energy consumption of the refrigerator 100 and improving the refrigeration efficiency of the refrigerator 100.

[0073] Combination Figure 3 and Figure 4 , Figure 4 yes Figure 3From the partial structural schematic diagram from another perspective, it can be understood that the air duct shell 123 includes a shell body, a first air duct component 130 and a second air duct component 131, the first air duct component 130 and the second air duct component 131 are respectively connected to the first heat exchange chamber 121, and the first air outlet 124 is located on the first air duct component 130, and the second air outlet 126 is located on the second air duct component 131. Therefore, the cold air in the first heat exchange chamber 121 can be transported to the first air outlet 124 through the first air duct component 130, and the air is supplied to the refrigeration chamber 112 from the first air outlet 124.

[0074] The cold air in the first heat exchange chamber 121 can also be transported to the second air outlet 126 through the second air duct component 131, and the air is supplied to the freezing chamber 113 from the second air outlet 126. Therefore, the first air duct component 130 can be used to supply air to the refrigerating chamber 112 alone, and the second air duct component 131 can be used to supply air to the freezing chamber 113 alone, so as to help control the air volume of both the refrigerating chamber 112 and the freezing chamber 113, and improve the accuracy of temperature control. In addition, in order to save the volume of the first partition 111, the thickness of both the first air duct component 130 and the second air duct component 131 is less than or equal to the thickness of the air duct housing 123, so as to compress the thickness of the air duct assembly 120, help install the air duct assembly 120, multiple evaporators and multiple heaters in the first partition 111, and help adjust the positions of the first air outlet 124 and the second air outlet 126 on the housing body to supply air to the refrigerating chamber 112 and the freezing chamber 113.

[0075] It can be understood that the first air duct component 130 and the second air duct component 131 are respectively arranged at the top of the air duct shell 123, that is, the top of the shell body, and the first air duct component 130 and the second air duct component 131 are respectively arranged along the length direction of the air duct shell 123. At the same time, the first air duct component 130 and the second air duct component 131 are respectively extended along the height direction of the air duct shell 123, thereby utilizing the space of the first partition 111 in height, saving the space of the air duct assembly 120 in width, effectively reducing the thickness of the first partition 111, and facilitating the placement of the first partition 111 in the refrigerator body 110.

[0076] The first air duct component 130 and the second air duct component 131 extend along the height direction of the air duct housing 123, respectively, so that the air outlets can be arranged according to the respective sizes of the refrigerating chamber 112 and the freezing chamber 113. Figure 3 and Figure 4, three first air outlets 124 are provided on the air duct housing 123, the three first air outlets 124 are spaced apart on the first air duct component 130, and the three first air outlets 124 are all oriented toward one side of the refrigerating chamber 112; and four second air outlets 126 can be provided, wherein three second air outlets 126 are spaced apart on the second air duct component 131, one second air outlet 126 is located on the housing body, and the plurality of second air outlets 126 are all oriented toward one side of the freezing chamber 113. The first air duct component 130 and the second air duct component 131 extend in the height direction of the air duct housing 123, which can increase the positions available for the arrangement of the air outlets, so that a plurality of air outlets can be provided to supply air to the refrigerating chamber 112 and the freezing chamber 113, thereby improving the air supply efficiency. The number and positions of the first air outlet 124 and the second air outlet 126 may be adjusted according to the sizes of the refrigerating chamber 112 and the freezing chamber 113 to improve the air supply effect of the freezing chamber 113 and the refrigerating chamber 112 .

[0077] It should be noted that the first air outlet 124 is distributed at the upper part of the refrigerating chamber 112, while the first return air outlet 125 is distributed at the bottom of the refrigerating chamber 112; accordingly, the second air outlet 126 is distributed at the upper part of the freezing chamber 113, while the second return air outlet 127 is distributed at the bottom of the freezing chamber 113, so that the cold air can flow from top to bottom in the two chambers, thereby improving the utilization rate of the cold air and the refrigeration efficiency.

[0078] It can be understood that since the first air duct component 130 is used to supply air to the refrigerating chamber 112 and the second air duct component 131 is used to supply air to the freezing chamber 113, and the temperature of the refrigerating chamber 112 is higher than that of the freezing chamber 113, but the first heat exchange cavity 121 is connected to the first air duct component 130 and the second air duct component 131 respectively, the cold air is simultaneously transported to the first air duct component 130 and the second air duct component 131 through the first heat exchange cavity 121.

[0079] Therefore, a first damper 133 is provided between the first air duct component 130 and the first heat exchange chamber 121. The first damper 133 can adjust the size of the connecting area between the first air duct component 130 and the first heat exchange chamber 121, that is, control whether the first air duct component 130 is connected with the first heat exchange chamber 121, thereby adjusting the air volume delivered from the first heat exchange chamber 121 to the first air duct component 130, and further adjusting the air supply volume to the refrigerating chamber 112, thereby controlling the temperature of the refrigerating chamber 112.

[0080] It can be understood that a variable temperature chamber 114 is also provided in the box body 110, and the variable temperature chamber 114 is located below the refrigerating chamber 112, and the air duct shell 123 is also provided with a third air outlet 128 and a third return air outlet 129, and the third air outlet 128 and the third return air outlet 129 are respectively connected to the variable temperature chamber 114, and the third air outlet 128 is connected to the first heat exchange chamber 121, and the third return air outlet 129 is connected to the second heat exchange chamber 122. Therefore, the cold air of the variable temperature chamber 114 enters the second heat exchange chamber 122 of the air duct shell 123 through the third return air outlet 129 for heat exchange and cooling, and the cooled cold air enters the first heat exchange chamber 121 for secondary heat exchange, and the cold air after the secondary heat exchange is transported to the variable temperature chamber 114 through the third air outlet 128. The third return air inlet 129 is located on the side wall of the variable temperature chamber 114 , that is, the third return air inlet 129 and the second return air inlet 127 are located at different positions, so as to avoid direct intersection of the return air of the variable temperature chamber 114 with the return air of the freezing chamber 113 , which would cause rapid frost on the second evaporator 150 .

[0081] It is understandable that a second partition 115 is further provided in the box body 110, and the second partition 115 is used to separate the refrigerating chamber 112 from the variable temperature chamber 114, that is, the second partition 115 is located between the refrigerating chamber 112 and the variable temperature chamber 114. The air duct housing 123 is provided with a third air duct component 132, and the third air duct component 132 is located in the second partition 115. The third air duct component 132 is communicated with the first heat exchange chamber 121, and the third air outlet 128 is located in the third air duct component 132, so that the cold air after heat exchange in the first heat exchange chamber 121 is transported to the third air outlet 128 through the third air duct component 132, and is supplied to the variable temperature chamber 114 through the third air outlet 128. Therefore, it is possible to realize air supply and cooling of the variable temperature chamber 114 while saving the space of the variable temperature chamber 114.

[0082] It can be understood that since the temperature of the variable temperature chamber 114 can be adjusted according to user needs, a second air gate 134 is provided between the third air duct component 132 and the first heat exchange chamber 121. The second air gate 134 can adjust the size of the area between the third air duct component 132 and the first heat exchange chamber 121, that is, control whether the third air duct component 132 is connected to the first heat exchange chamber 121, thereby adjusting the air volume delivered from the first heat exchange chamber 121 to the third air duct component 132, and then adjusting the air volume delivered to the variable temperature chamber 114, thereby accurately controlling the temperature of the variable temperature chamber 114.

[0083] It should be noted that, during the assembly process of the refrigerator 100 of the embodiment, multiple evaporators and multiple heaters are installed in the air duct shell 123, and then the air duct assembly 120, multiple evaporators and multiple heaters are integrally loaded into the space reserved in the first partition 111. After being assembled in place, foaming is performed, so that the air duct assembly 120, multiple evaporators and multiple heaters are pre-buried in the box body 110, and the structure is stable and reliable.

[0084] Based on the structure of the refrigerator 100 described above, various embodiments of a method for controlling a refrigerator of the present invention are proposed.

[0085] Reference Figure 5 , Figure 5 is a flow chart of a refrigerator control method provided by an embodiment of the present invention. The refrigerator control method can be applied to Figures 1 to 4 The refrigerator 100 shown in the figure, the control method of the refrigerator includes but is not limited to the following steps:

[0086] Step S101, obtaining a first operating parameter of a first evaporator and a second operating parameter of a second evaporator;

[0087] Step S102 , in response to the first operating parameter and / or the second operating parameter satisfying a preset defrosting condition, controlling the first heater and the second heater to independently defrost the first evaporator and the second evaporator respectively.

[0088] It is understandable that the frost risk of the first evaporator and the second evaporator are judged respectively by the first working parameter of the first evaporator and the working parameter of the second evaporator, and it is judged whether the first evaporator and the second evaporator need to run the heater for defrosting. At the same time, the first evaporator and the second evaporator are respectively equipped with heaters for heating and defrosting, that is, one side of the first evaporator is provided with a first heater for heating and defrosting the first evaporator, and one side of the second evaporator is provided with a second heater for heating and defrosting the second evaporator. When the first working parameter and / or the second working parameter meet the preset defrosting conditions, that is, the first evaporator and / or the second evaporator are stored in the frosting wind direction, the corresponding heater is controlled to operate, and the corresponding evaporator is independently heated and defrosted, thereby shortening the defrosting time. By using different heaters to perform independent defrosting operations on the corresponding evaporators, the defrosting efficiency can be improved, and the long-term operation of the heater can be avoided to increase energy consumption and affect the heat exchange efficiency.

[0089] It can be understood that the first operating parameter can be the first evaporation temperature of the first evaporator, and the second operating parameter can be the second evaporation temperature of the second evaporator. The preset defrosting condition can be that the first operating parameter reaches the first temperature threshold, or the second evaporation temperature reaches the second temperature threshold, which is equivalent to that when the first evaporation temperature of the first evaporator reaches the first temperature threshold, it can be considered that the first evaporator currently has no risk of frost, so the first heater can be controlled to stop working; correspondingly, when the second evaporation temperature of the second evaporator reaches the second temperature threshold, it can be considered that the second evaporator currently has no risk of frost, so the second heater can be controlled to stop working.

[0090] Combination Figure 6 , Figure 6: is a defrost control flow chart of the control method of the refrigerator provided by the embodiment of the present invention. It can be understood that the refrigerator performs conventional refrigeration. When there is a refrigeration demand in the compartment, the compressor is driven to start, and the first evaporator and the second evaporator are synchronously operated. The first working parameter can be the operating time of the first evaporator, and the second working parameter can be the operating time of the second evaporator. When the evaporator runs for a long time, the surface of the evaporator is prone to frost. Therefore, the preset defrost condition is that the first working parameter reaches the first defrost cycle, or the second working parameter reaches the second defrost cycle, which is equivalent to that when the operating time of the first evaporator reaches the first defrost cycle, it can be considered that the first evaporator has a risk of frost; and when the operating time of the second evaporator reaches the second defrost cycle, it can be considered that the second evaporator has a risk of frost. Since the heat exchange amount of the first evaporator and the second evaporator may be the same or different, even if the first evaporator and the second evaporator are synchronously operated, the frost risk of the first evaporator and the second evaporator at the same time may be the same or different. Therefore, the first defrost cycle and the second defrost cycle may be the same or different, so that it is possible to single and accurately judge whether each evaporator has a risk of frost. When the first working parameter reaches the first defrost cycle, the first heater is controlled to work and the first evaporator is heated and defrosted alone; when the first heater completes the heating and defrosting operation, it stops working and continues to perform normal refrigeration of the cold storage room. When the operating time of the first heater reaches a preset time threshold or the temperature of the first evaporator reaches a preset temperature threshold, it can be considered that the heating and defrosting operation is completed.

[0091] It should be noted that the first defrost cycle and the second defrost cycle can be pre-set fixed parameters, or can be adjusted according to the temperature and humidity of the corresponding compartment, the number and time of the compartment door opening and closing, and the load state of the corresponding evaporator. For example, the first defrost cycle can determine the initial defrost cycle according to the current temperature and humidity of the refrigerating chamber. The lower the temperature and the higher the humidity, the shorter the initial defrost cycle. After determining the initial defrost cycle, the number of door openings and closings of the refrigerating chamber and the length of time the door is opened are recorded, and the initial defrost cycle is reduced according to the number of door openings and closings and the length of time the door is opened. The more the number of door openings and closings or the longer the door is opened, the more the initial defrost cycle is reduced, and then the first defrost cycle is determined. In addition, the first defrost cycle will also be adjusted according to the operating time of the first heater. For example, when the continuous operating time of the first heater exceeds a predetermined threshold, it can be considered that the first evaporator has a high risk of frosting and needs to be frequently heated for defrosting to reduce the risk of frosting. Therefore, when the continuous operating time of the first heater exceeds a predetermined threshold, the first defrost cycle can be reduced.

[0092] It is understandable that when the first working parameter meets the preset defrost condition, that is, it can be considered that the first evaporator has a risk of frost, it is necessary to control the first heater to heat and defrost the first evaporator separately. In order to ensure that the first evaporator can eliminate the risk of frost, it is necessary to control the first heater to run the first defrost time. Correspondingly, when the second working parameter meets the preset defrost condition, it is necessary to control the second heater to run the second defrost time. Since the heat exchange amount of the first evaporator and the second evaporator may be different, and the heating efficiency of the first heater and the second heater may also be different, the first defrost time that ensures that the first evaporator eliminates the risk of frost is the same or different from the second defrost time that ensures that the second evaporator eliminates the risk of frost. According to different evaporators and different heaters, controlling the corresponding heater to run the corresponding heating defrost time can improve the defrost efficiency.
