The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1 to 3, the embodiment of the present utility model provides a refrigeration apparatus 100, where the refrigeration apparatus 100 may be a refrigerator, a freezer, or the like.

The refrigeration device 100 includes a cabinet 10 and a refrigeration system assembled to the cabinet 10, the refrigeration system providing cooling to the interior of the cabinet 10. The refrigeration system may include, among other things, an evaporator 20, a compressor, a condenser, a throttling element, and the like.

The cabinet 10 is divided into an evaporator accommodating chamber 11 and a storage compartment, and the evaporator accommodating chamber 11 and the storage compartment may be stacked and distributed, for example, the evaporator accommodating chamber 11 and the storage compartment may be distributed along the height direction of the cabinet 10.

The evaporator receiving chamber 11 may be used to receive the evaporator 20. The suction side 21 and the supply side 22 of the evaporator 20 may be opposite, e.g., the supply side 22 of the evaporator 20 may be facing the rear side of the cabinet 10, and the suction side 21 of the evaporator 20 may be facing the cabinet door of the cabinet 10.

The storage compartment may be used as a compartment of different temperatures, for example, the storage compartment may be used as a freezer compartment 12, a variable temperature compartment 13, a refrigerator compartment 14 or other compartments.

Wherein, the temperature of the freezing chamber 12 can be in the range of-24 to-16 degrees, the temperature of the temperature changing chamber 13 can be in the range of-18 to 5 degrees, and the temperature of the refrigerating chamber 14 can be in the range of 2 to 8 degrees. In other embodiments, the temperature range of the storage compartment may be other ranges.

In some embodiments, the number of storage compartments is plural, and the plurality of storage compartments may be distributed along the height direction of the cabinet 10. The term "plurality" in this application means greater than or equal to two, for example, the number of storage compartments may be two, three, four or other numbers.

In some embodiments, the number of storage compartments is two, one of which may be the freezer compartment 12 and the other may be the variable temperature compartment 13.

In some embodiments, the number of storage compartments is three, one storage compartment can be used as the freezer compartment 12, one storage compartment can be used as the temperature change compartment 13, and the remaining storage compartment can be used as the refrigerator compartment 14.

In some embodiments, the freezing compartment 12 may be located between the evaporator receiving chamber 11 and the temperature changing compartment 13, so that the evaporator 20 does not need to be disposed at the rear side of the cabinet 10, thereby reducing the space occupied by the evaporator 20 in the thickness direction of the cabinet 10 and improving the available space in the thickness direction of the cabinet 10.

In one use scenario, where refrigeration appliance 100 is normally placed for use, evaporator receiving cavity 11 may be located above freezer compartment 12 and variable temperature compartment 13 may be located below freezer compartment 12.

In some embodiments, where the cabinet 10 includes a refrigerated compartment 14, the evaporator receiving cavity 11 may be located between the refrigerated compartment 14 and the freezer compartment 12. For example, in the case of normal placement and use of the refrigeration appliance 100, the refrigerated compartment 14 may be located above the evaporator receiving compartment 11.

The evaporator 20 can provide cooling to the storage compartment. In some embodiments, the refrigeration device 100 may further include an air delivery duct, an air inlet of the air delivery duct is connected to the evaporator receiving chamber 11, and an air outlet of the air delivery duct is connected to the storage compartment. In this way, the cool air blown out from the evaporator 20 can be delivered to the storage compartment through the air delivery duct.

In some embodiments, the number of air delivery channels may be multiple, and the cool air blown by the evaporator 20 may be delivered to different storage compartments through different air delivery channels.

For example, in some embodiments, the refrigeration appliance 100 may further include a refrigeration delivery duct, an air inlet of which may be in communication with the evaporator receiving chamber 11, and an air outlet of which may be in communication with the refrigeration compartment 12. In this manner, evaporator 20 may provide cooling to freezer compartment 12 via the refrigeration delivery conduit.

For another example, in some embodiments, the refrigeration appliance 100 can further include a variable temperature delivery duct, an air inlet of which can be in communication with the evaporator receiving chamber 11, and an air outlet of which can be in communication with the variable temperature compartment 13. Thus, evaporator 20 can provide cooling to temperature change compartment 13 through the temperature change delivery conduit.

For another example, in some embodiments, the refrigeration appliance 100 may further include a refrigeration delivery duct, an air inlet of which may be in communication with the evaporator receiving cavity 11, and an air outlet of which may be in communication with the refrigeration compartment 14. In this manner, evaporator 20 may provide cooling to refrigerated compartment 14 through a refrigerated delivery duct.

In some embodiments, the air delivery duct of the refrigeration appliance 100 may be disposed on the rear side of the cabinet 10. For example, the cabinet 10 may include a first sidewall 15, a second sidewall 16, and a rear sidewall 17, the first sidewall 15 being opposite the second sidewall 16, the rear sidewall 17 being connected between the first sidewall 15 and the second sidewall 16. The delivery duct may be disposed within the rear side wall 17, thus helping to reduce the spatial location within the storage compartment occupied by the delivery duct, and also helping to increase the utilization of space within the rear side wall 17.

For example, a freezer delivery duct may be disposed within the rear sidewall 17, and an air outlet of the freezer delivery duct may be in communication with the rear of the freezer compartment 12. For example, a variable-temperature air supply duct may be disposed in the rear sidewall 17, and an air outlet of the variable-temperature air supply duct may be connected to the rear of the variable-temperature chamber 13. For another example, a refrigerating air supply duct may be disposed in the rear side wall 17, and an air outlet of the refrigerating air supply duct may communicate with the rear of the refrigerating compartment 14.

In some embodiments, the refrigeration appliance 100 may also include a supply air door, which may be disposed in the supply air duct. Therefore, the opening and closing degree of the air supply duct can be adjusted by the air supply air door so as to adjust the air quantity of the evaporator 20 conveyed to the storage compartment, and the storage compartment can be well kept at a set temperature.

For example, in some embodiments, the refrigeration appliance 100 may also include a refrigeration supply air door, which may be disposed in the refrigeration supply air duct. In this way, the refrigeration blower can adjust the amount of air delivered by the evaporator 20 to the refrigeration compartment 12.

For another example, in some embodiments, the refrigeration appliance 100 can further include a variable temperature air supply damper, which can be disposed in the variable temperature air supply duct. In this way, the variable temperature air supply damper can adjust the air quantity delivered to the variable temperature chamber 13 by the evaporator 20.

For another example, in some embodiments, the refrigeration appliance 100 may also include a refrigeration supply air door, which may be disposed in the refrigeration supply air duct. In this manner, the refrigeration supply damper can regulate the amount of air delivered by the evaporator 20 to the refrigerated compartment 14.

In some embodiments, the refrigeration device 100 may further include a return air duct, an air inlet of the return air duct being in communication with the storage compartment, and an air outlet of the return air duct being in communication with the evaporator receiving chamber 11. In this way, the air return duct is helpful for the air in the storage compartment to return back to the evaporator accommodating cavity 11 and exchange heat through the evaporator 20, so that the air after subsequent heat exchange is conveniently conveyed to the storage compartment again through the air supply duct, and circulation is formed.

In some embodiments, the air return duct may be disposed in the side wall of the cabinet body 10, or the air return duct may be disposed between the storage compartment and the evaporator accommodating cavity 11, which may be specifically selected according to practical situations.

In some embodiments, the number of the air return channels is multiple, and different storage compartments can adopt different air return channels for returning air to the evaporator accommodating cavity 11.

In some embodiments, the refrigeration appliance 100 may further include a refrigeration return air duct, an air inlet of which may be in communication with the refrigeration compartment 12, and an air outlet of which may be in communication with the evaporator receiving cavity 11. In this way, the air in the freezer compartment 12 can be returned to the evaporator receiving chamber 11 via the freezer return air duct and heat exchanged via the evaporator 20.

In some embodiments, a freeze back air channel may be provided between the evaporator receiving chamber 11 and the freezer compartment 12. For example, as shown in fig. 2 and 4, the cabinet 10 may include a carrying partition 18 separating the evaporator receiving chamber 11 and the freezing chamber 12, the carrying partition 18 may be provided with a return air through hole 181, an inlet of the return air through hole 181 may be communicated with the freezing chamber 12, and an outlet of the return air through hole 181 may be communicated with the evaporator receiving chamber 11. In this way, the return air through hole 181 can be used as a refrigerating return air duct, so that the air in the refrigerating compartment 12 can be returned to the evaporator accommodating chamber 11 through the return air through hole 181.

The return air through hole 181 has a simple structure and a short path, which is helpful to simplify the return air design between the freezing compartment 12 and the evaporator accommodating cavity 11 and improve the heat exchange efficiency of the evaporator 20.

In some embodiments, the return air through hole 181 may be located in front of the evaporator 20 such that the return air through hole 181 is closer to the cabinet door of the cabinet 10 than the evaporator 20.

In some embodiments, the refrigeration device 100 can further include a temperature swing return air duct, an air inlet of which can be in communication with the temperature swing compartment 13, and an air outlet of which can be in communication with the evaporator receiving cavity 11. In this way, the air in the temperature changing compartment 13 can be returned to the evaporator accommodating chamber 11 through the temperature changing return air duct and heat exchanged through the evaporator 20.

In some embodiments, the refrigeration appliance 100 can include multiple variable temperature return air ducts to facilitate the use of different amounts of variable temperature return air ducts for return air depending on the set temperature of the variable temperature compartment 13. For example, the refrigeration unit 100 can include two variable temperature return air ducts as the first return air duct 30 and the second return air duct 40, respectively.

The first air return duct 30 is provided with a first air inlet 31 and a first air outlet 32, the first air inlet 31 is communicated with the variable-temperature chamber 13, and the first air outlet 32 is communicated with the evaporator accommodating cavity 11. The second air return duct 40 has a second air inlet 41 and a second air outlet 42, the second air inlet 41 is communicated with the variable temperature chamber 13, and the second air outlet 42 is communicated with the freezing chamber 12. The refrigeration appliance 100 may further include a damper 50, and the damper 50 may be disposed in the second return air duct 40.

When the temperature set in the variable temperature compartment 13 is high, for example, when the variable temperature compartment 13 is used as a refrigerating compartment, the variable temperature compartment 13 can return air through a variable temperature return air duct. For example, when the air door 50 is closed, the temperature changing compartment 13 can return air to the evaporator accommodating cavity 11 through the first air return duct 30, and the air of the temperature changing compartment 13 cannot return air to the evaporator accommodating cavity 11 through the second air return duct 40 and the freezing compartment 12 through the air door 50, so that the situation of frosting condensation generated by the temperature difference between the temperature changing compartment 13 and the freezing compartment 12 is reduced.

When the temperature set in the variable temperature chamber 13 is low, for example, when the variable temperature chamber 13 is used as a freezing chamber, the variable temperature chamber 13 can return air through two variable temperature return air channels. For example, the air door 50 is opened, so that the temperature changing chamber 13 can return air to the evaporator accommodating cavity 11 through the first air return duct 30, and can return air to the evaporator accommodating cavity 11 through the second air return duct 40 by the freezing chamber 12, thereby helping to ensure the air return quantity of the temperature changing chamber 13. In addition, since the difference between the temperature in the temperature changing compartment 13 and the temperature in the freezing compartment 12 is small, the air entering the freezing compartment 12 from the second return air duct 40 is mixed with the air in the freezing compartment 12, and the frost and dew are not easily generated.

In some embodiments, the damper 50 may be a motorized damper, and the damper 50 may be controlled to open and close by a control board of the refrigeration appliance 100.

In some embodiments, the first return air duct 30 may be disposed in a side wall of the cabinet 10, which helps to reduce the space occupied by the first return air duct 30 in the temperature change compartment 13 and the evaporator receiving chamber 11, and also helps to improve the utilization of the space in the side wall of the cabinet 10.

In some embodiments, the first return air duct 30 may be disposed within the first side wall 15, which may help to increase the space utilization of the first side wall 15.

In some embodiments, the first air outlet 32 may be located at an end of the first side wall 15 remote from the rear side wall 17, to facilitate adapting to the layout of the air suction side 21 of the evaporator 20 facing away from the rear side wall 17.

In some embodiments, a second return duct 40 may be disposed between freezer compartment 12 and variable temperature compartment 13. For example, the cabinet 10 may further include a partition 19 between the freezing compartment 12 and the temperature changing compartment 13, and the second return air duct 40 may be provided to the partition 19. In this way, the second air return duct 40 has a simple structure and a shorter path, which is helpful to simplify the manufacture of the second air return duct 40, and also makes the second air return duct 40 not occupy the side walls (such as the first side wall 15 and the second side wall 16) with limited area in the cabinet 10, and is also helpful to avoid the limitation of the layout of the first air return duct 30 and the second air return duct 40 caused by the same side wall, and is helpful to disperse the first air return duct 30 and the second air return duct 40 in different positions, so that the arrangement is convenient.

In some embodiments, the distance between the second air return duct 40 and the first side wall 15 may be greater than the distance between the second air return duct 40 and the second side wall 16, so that the second air return duct 40 and the first air return duct 30 may keep a certain distance, and the two air return ducts may be dispersed in different positions, which helps to improve the air return effect of the temperature changing compartment 13.

In some embodiments, the second air return duct 40 is located at an end of the partition 19 facing away from the rear sidewall 17, so that the second air inlet 41 of the second air return duct 40 is spaced far from the air outlet of the temperature changing chamber 13, which is helpful for reducing the situation that the cooling capacity of the temperature changing chamber 13 is not cooled by the temperature changing chamber 13 but is directly returned to the evaporator accommodating cavity 11 through the second air return duct 40.

In some embodiments, the damper 50 may be located at the second air inlet 41, which may facilitate installation and maintenance of the damper 50.

In some embodiments, the refrigeration appliance 100 may further include a shield 60, where the shield 60 may be coupled to the partition 19 and cover the damper 50, and where the shield 60 is provided with a vent 61. In this manner, the hood 60 may provide some protection to the damper 50 and the vent 61 may assist in blowing air from within the temperature change compartment 13 through the hood 60 toward the second air inlet 41.

In some embodiments, the shield 60 may be positioned within the freezer compartment 12, and the shield 60 helps to avoid the damper 50 from being blocked by items within the freezer compartment 12 and from opening.

In some embodiments, the refrigeration appliance 100 may further include a refrigeration return duct 70, the air inlet 71 of the refrigeration return duct 70 may be in communication with the refrigerated compartment 14, and the air outlet 72 of the refrigeration return duct 70 may be in communication with the evaporator receiving cavity 11. In this way, the air in the refrigerated compartment 14 can be returned to the evaporator receiving compartment 11 via the refrigerated return duct 70 and heat exchanged via the evaporator 20.

In some embodiments, the refrigerated return air duct 70 may be disposed within a side wall of the cabinet 10, thus helping to reduce the spatial locations of the refrigerated return air duct 70 within the refrigerated compartment 14 and the evaporator receiving cavity 11 and also helping to increase the utilization of space within the side wall of the cabinet 10.

In some embodiments, the refrigeration air return duct 70 may be disposed in the first side wall 15, and since the evaporator accommodating cavity 11 is located between the refrigeration compartment 14 and the temperature changing compartment 13, the refrigeration compartment 14 and the temperature changing compartment 13 are distributed along the height direction of the cabinet 10, and then the refrigeration air return duct 70 and the first air return duct 30 are also distributed along the height direction of the cabinet 10 in the first side wall 15, so that the refrigeration air return duct 70 and the first air return duct 30 are disposed at different heights, and the two have less interference effect in the first side wall 15 with each other with limited space.

In some embodiments, the refrigeration appliance 100 may further include a vacuum insulation panel (Vacuum Insulation Panel, VIP), the vacuum insulation panel 91 may be disposed within the first side wall 15 of the cabinet 10, and the vacuum insulation panel 91 may be located on a side of the first return air duct 30 facing away from the temperature change compartment 13. In this way, the air in the first air return duct 30 is kept warm, and condensation is not easy to occur on the outer surface of the first side wall 15.

In addition, the vacuum insulation panel 91 may also be located on a side of the refrigerated return air duct 70 facing away from the refrigerated compartment 14 such that the vacuum insulation panel 91 is also capable of insulating the air within the refrigerated return air duct 70. Wherein, the height of the vacuum insulation panel 91 may be higher than the sum of the heights of the first return air duct 30 and the refrigerating return air duct 70.

In the refrigeration device 100 provided by the embodiment of the utility model, the first air inlet 31 of the first air return duct 30 is communicated with the variable-temperature chamber 13, and the first air outlet 32 is communicated with the evaporator accommodating cavity 11. The second air return duct 40 is arranged on the partition plate 19 between the freezing compartment 12 and the variable temperature compartment 13, the second air inlet 41 of the second air return duct 40 is communicated with the variable temperature compartment 13, the second air outlet 42 is communicated with the freezing compartment 12, and the air door 50 is arranged on the second air return duct 40. In this way, when the temperature set in the temperature changing compartment 13 is high, for example, when the temperature changing compartment 13 is used as a refrigerating compartment, the temperature changing compartment 13 returns to the evaporator accommodating chamber 11 through the first return air duct 30, and the air door 50 is closed, which contributes to reducing the occurrence of frosting and condensation of the temperature changing compartment 13 and the refrigerating compartment 12 due to a large temperature difference. When the temperature set in the temperature changing chamber 13 is low, for example, when the temperature changing chamber 13 is used as a freezing chamber, the air door 50 is opened, and the temperature changing chamber 13 returns air to the evaporator accommodating cavity 11 through the first return air duct 30 and returns air to the evaporator accommodating cavity 11 through the second return air duct 40 by the freezing chamber 12, so that the air return quantity of the temperature changing chamber 13 is ensured.
