Description

Technical Field

[0001] The present application relates to the technical field of low-temperature storage equipment, and in particular to a refrigerator. Background Art

[0002] A refrigerator is an electrical device that can maintain a constant low temperature. It can provide appropriate temperature and humidity conditions for fresh vegetables, fruits, meat and other ingredients, thereby improving the preservation of food.

[0003] Refrigerators can be generally divided into single-system refrigerators and dual-system refrigerators according to different usage requirements. Single-system refrigerators only need one refrigeration system, with a relatively simple structure and small size, which is suitable for small families or occasions that require simple refrigeration functions. Dual-system refrigerators have two independent refrigeration systems, one for the refrigerator and the other for the freezer. They have a larger capacity and more flexible temperature control, which is suitable for occasions that require higher storage of items.

[0004] In order to ensure the refrigeration effect in the refrigerator, the existing single-system refrigerator generally sets a large-diameter air inlet at the bottom of the refrigerator; the refrigeration evaporator of the dual-system refrigerator is generally set in the box, and there is no need to set a refrigeration air inlet on the side wall of the box. The refrigeration evaporator will produce condensed water, so it is necessary to set a drainage hole at the bottom of the refrigerator, and the diameter of the drainage hole is generally small; therefore, the box of the single-system refrigerator and the dual-system refrigerator cannot be universal, and the single-system refrigerator and the dual-system refrigerator generally need to design different boxes. Each box needs to be molded independently, and the cost of the mold is high, which increases the manufacturing cost to a certain extent.

[0005] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0043] See also Figure 1 and Figure 2 The present application provides a refrigerator, including a box body 1. The box body 1 may include a box shell 12. The box shell 12 is configured as an external structure of the box body 1. The box shell 12 may be roughly in the shape of a rectangular parallelepiped. It is understood that in other embodiments, the box shell 12 may also adopt a hollow structure of other shapes.

[0044] In some embodiments of the present application, a storage compartment may be provided in the box body 1. The storage compartment may be used to store items at low temperatures to improve the preservation effect of the items.

[0045] In some embodiments of the present application, a plurality of mutually separated storage compartments may be provided in the box body 1. Each separated storage compartment may be used as an independent storage space for low-temperature storage. The storage compartment may be a freezer compartment. The storage compartment may be a refrigerator compartment 112. The storage compartment may meet different refrigeration requirements such as freezing and refrigeration according to the types of food materials, and perform storage. For example, the refrigerator compartment 112 is suitable for storing vegetables, fruits, beverages, etc. The freezer compartment is suitable for storing meat, quick-frozen food, etc.

[0046] In some embodiments of the present application, in order to meet more user requirements, the storage compartment may also include a fresh-keeping drawer and a variable temperature chamber, etc.

[0047] In some embodiments of the present application, multiple storage compartments may be arranged in an upper and lower partition.

[0048] In some embodiments of the present application, multiple storage compartments may be arranged in left and right partitions.

[0049] In some embodiments of the present application, the box body 1 may be provided with a box liner 11. The box liner 11 is arranged in the box shell 12. The interior of the box liner 11 is hollow. A storage compartment is formed in the box liner 11. A take-in and take-out opening 111 is formed on the front side of the box liner 11. Items can be put into the corresponding storage compartment from the take-in and take-out opening 111. It is understandable that a plurality of box liner 11 may be arranged in the box body 1. One or more storage compartments may be formed in each box liner 11.

[0050] Figure 3 This is a schematic structural diagram of the box body (minus the box shell) provided in this application at the first visual perspective. Figure 4 This is a schematic diagram of the structure of the box body (without the box shell) provided in this application under the second visual perspective.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the refrigerator may be a dual-system refrigerator. The refrigerator compartment 112 and the freezer compartment of the refrigerator are controlled by different refrigeration systems respectively.

[0052] The refrigerator can be a single-system refrigerator. The refrigerator is controlled by a set of refrigeration systems.

[0053] The housing 1 may include a condenser (not shown). The condenser may be a built-in condenser of the refrigerator. The condenser may be arranged between the housing 12 and the housing 11, without taking up additional space, so that the structure of the refrigerator is more compact.

[0054] In some embodiments of the present application, the condenser may be disposed on the side of the box body 1. The condenser may be connected to the inner side wall of the box shell 12.

[0055] In some other embodiments, the condenser may also be arranged at the back of the box body 1. The condenser is connected to the back plate of the box body 1.

[0056] The condenser is isolated from the freezer and the refrigerator 112, does not occupy the refrigeration space, and does not affect the convenience of users to take and put items. The condenser is tightly combined with the box shell 12, which can reduce vibration and noise conduction and reduce the noise when the refrigerator is running. The condenser is connected to the box shell 12 or the condenser is connected to the back plate of the box body 1, so that the condenser is in closer contact with the external environment of the refrigerator, which is convenient for heat dissipation, effectively dissipating the heat released by the refrigerant to the surrounding environment, and improving the refrigeration efficiency.

[0057] The refrigerator may include a freezing evaporator (not shown). In some embodiments, the freezing evaporator may be disposed between the box shell 12 and the box liner 11. In other embodiments, the freezing evaporator may be disposed in the freezing chamber. The freezing evaporator may be connected to the condenser and perform heat exchange with the condenser, thereby reducing the temperature of the freezing chamber and achieving an evaporative cooling effect.

[0058] The refrigerator may include a refrigeration evaporator 2. The refrigeration evaporator 2 may be disposed in the refrigeration chamber 112. The refrigeration evaporator 2 is connected to the condenser and performs heat exchange with the condenser, thereby reducing the temperature of the refrigeration chamber 112 and achieving an evaporative cooling effect.

[0059] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the refrigerator may include a refrigeration duct assembly 7. The refrigeration duct assembly 7 is arranged in the refrigeration chamber 112. The refrigeration duct assembly 7 may be connected to the refrigeration evaporator 2. The refrigeration duct assembly 7 may include a fan 71. The fan 71 can accelerate the air flow speed of the entire refrigeration chamber 112, so that the hot air in the refrigeration chamber 112 can pass through the refrigeration evaporator 2 more quickly, thereby accelerating heat exchange and promoting cooling efficiency.

[0060] like Figures 2 to 4 As shown, in some embodiments of the present application, a first installation area 113 is provided on a side wall of the refrigerating chamber 112. The first installation area 113 is provided on the back plate of the refrigerating chamber 112. The first installation area 113 is provided to be concave toward the back of the refrigerator, so that the space in the thickness direction of the refrigerator can be increased at the position of the first installation area 113, thereby increasing the storage space of the refrigerating chamber 112 to a certain extent. The refrigerating evaporator 2 is installed in the first installation area 113.

[0061] like Figures 2 to 4 As shown, in some embodiments of the present application, a second installation area 115 may also be provided in the refrigerating chamber 112. The second installation area 115 is provided on a side wall of the refrigerating chamber. The second installation area 115 is provided on the back plate of the refrigerating chamber 112. The second installation area 115 is located above the first installation area 113. The refrigerating air duct assembly 7 is provided in the second installation area 115, that is, the refrigerating air duct assembly 7 is provided above the refrigerating evaporator 2, which shortens the distance between the refrigerating air duct assembly 7 and the refrigerating evaporator 2, simplifies the air duct structure of the refrigerating air duct assembly 7, can reduce the space occupied by the refrigerating air duct assembly 7, and thus increases the storage space of the refrigerating chamber 112.

[0062] Figure 5 This is a schematic structural diagram of the box body (without box shell) provided in this application under the third perspective. Figure 6 for Figure 5 Cross-sectional view along direction BB.

[0063] like Figure 5 and Figure 6As shown, in some embodiments of the present application, the box body 1 includes an air duct baffle 8. The air duct baffle 8 is arranged in the refrigerating chamber 112. The air duct baffle 8 is located on the side of the refrigerating air duct assembly 7 and the refrigerating evaporator 2 away from the inner wall of the box 11. The air duct baffle 8 can adjust and control the flow of cold air in the refrigerating chamber 112, ensuring that the cold air can be evenly distributed in the entire refrigerating chamber 112, avoiding the situation where the local temperature is too high or too low, and also avoiding the cold air directly blowing on the food and affecting the freshness and taste of the food.

[0064] like Figure 5 and Figure 6 As shown, in some embodiments of the present application, a refrigeration return air port 81 may be provided on the air duct baffle 8. The refrigeration return air port 81 is provided at the lower part of the air duct baffle 8, below the refrigeration evaporator 2, so that the return air of the refrigeration chamber 112 can completely pass through the refrigeration evaporator 2, thereby improving the refrigeration effect of the refrigeration chamber 112.

[0065] In some embodiments, a plurality of refrigeration return air vents 81 are provided at the lower portion of the air duct baffle 8. The plurality of refrigeration return air vents 81 are sequentially arranged along the length direction of the refrigeration evaporator 2, so that the hot air (return air) in the refrigeration room can pass through the refrigeration evaporator 2 more evenly.

[0066] like Figures 2 to 4 As shown, in some embodiments of the present application, a third installation area 116 may be provided on the side wall of the refrigerating chamber 112. The third installation area 116 is formed with a protrusion extending toward the outside of the box 11. When the box 11 is used to prepare a dual-system refrigerator, the third installation area 116 can be used as a pending use area. When the box 11 is used for a single-system refrigerator, an opening can be provided in the third installation area 116, and the opening can be provided to communicate with the air duct assembly of the single-system refrigerator. That is, the third installation area 116 can be processed as a return air outlet of a single-system refrigerator.

[0067] Figure 7 This is a schematic structural diagram of the box body (without box shell) provided in this application under the fourth visual perspective.

[0068] like Figure 7 As shown, in some embodiments of the present application, a shelf assembly may be provided in the box 11 to form a shelf space for storing items.

[0069] The shelf assembly can be detachably arranged in the box 11, so that the shelf assembly can be removed from the box 11 for cleaning or changing the shelf space.

[0070] In some embodiments of the present application, the shelf assembly may include a shelf. The shelf is used to store items. The shelf may be provided as an integrated plate structure. In other embodiments, the shelf may also be provided as a plate structure that folds forward and backward or folds left and right. Alternatively, the shelf may be composed of a plurality of retractable or expandable shelf rods, and by changing the distance between the shelf rods, different loading planes may be formed, and different shelf spaces may be formed to meet the storage requirements of different items.

[0071] In some embodiments of the present application, a plurality of shelf assemblies may be provided in the refrigerating chamber 112. The plurality of shelf assemblies are spaced apart along the height direction of the refrigerating chamber 112. The shelf assembly located at the bottom is the first shelf assembly 5. The installation height of the refrigerating evaporator 2 is not higher than the first shelf assembly 5, so that the upper storage space of the refrigerating chamber 112 can be released.

[0072] A second shelf assembly 6 may be disposed above the first shelf assembly 5. The installation height of the refrigeration duct assembly 7 is not higher than the second shelf assembly 6, which shortens the distance between the refrigeration duct assembly 7 and the refrigeration evaporator 2 and improves the refrigeration effect. The higher the refrigeration duct assembly 7 is disposed in the refrigeration chamber 112, the more complex its structure is, and more shelf space is required, which reduces the space utilization rate of the refrigeration chamber 112.

[0073] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a groove 114 may be formed at the bottom of the refrigerating chamber 112. The groove 114 is arranged below the first mounting area 113 and can be used to receive condensed water generated by the refrigerating evaporator 2. A through hole 1142 may be formed at the bottom of the groove 114, and the through hole 1142 may be used as a drainage hole for the refrigerating chamber 112 of the dual-system refrigerator.

[0074] In other embodiments, the refrigerator is configured as a single-system refrigerator, and the through hole 1142 can be set as an air supply port of the single-system refrigerator.

[0075] like Figure 3 As shown, in some embodiments of the present application, the groove 114 is provided with a guide surface 1143 inclined toward the through hole 1142, so that the inner diameter of the groove 114 near the notch position is larger than the inner diameter of the groove 114 near the groove bottom position. The groove 114 is provided with a larger notch, which can be adapted to the size of the evaporator, so that the condensed water generated by the evaporator can directly drip into the groove 114, and slide into the bottom of the groove 114 through the guide surface 1143, and flow out of the refrigeration chamber 112 through the through hole 1142. The notch of the groove 114 can be set to be adapted to the length of the refrigeration evaporator 2, so that the condensed water generated by the refrigeration evaporator 2 can be quickly discharged, reducing the possibility of frosting.

[0076] In some other embodiments, the groove 114 is provided with the guide surface 1143 , which can blow the wind more evenly into the refrigerating chamber 112 when used as an air outlet of a single-system refrigerator, thereby improving the uniformity of the temperature in the refrigerating chamber 112 .

[0077] Figure 8 for Figure 4 Cross-sectional view along the GG direction.

[0078] like Figure 2 and Figure 8 As shown, in some embodiments of the present application, the guide surface 1143 may include a first surface 11431. The first surface 11431 is disposed on a side of the groove 114 away from the first mounting area 113. The first surface 11431 is configured to be inclined along the direction from the notch of the groove 114 to the groove bottom. The guide surface 1143 may include a second surface 11432. The second surface 11432 is connected to one side of the first surface 11431. The second surface 11432 is configured to be inclined along the direction from the notch of the groove 114 to the groove bottom. The guide surface 1143 may include a fourth surface 11434. The fourth surface 11434 is connected to the other side of the first surface 11431. The fourth surface 11434 is disposed opposite to the second surface 11432. The fourth surface 11434 is configured to be inclined along the direction from the notch of the groove 114 to the groove bottom. The through hole 1142 is disposed at the lowest point of the guide surface 1143. In the above, the inclined guide surface 1143 can not only realize the gradual reduction of the inner diameter from the opening of the groove 114 to the through hole 1142, but also enable the condensed water falling on the first surface 11431 to quickly fall to the bottom of the groove.

[0079] The guide surface 1143 also includes a third surface 11433. The first surface 11431, the second surface 11432, the third surface 11433 and the fourth surface 11434 enclose the inner circumference of the groove 114. The third surface 11433 is connected to the first installation area 113. The third surface 11433 and the first installation area 113 are located on the same vertical plane, so that the groove 114 can be located directly below the refrigeration evaporator 2, and the condensed water generated by the refrigeration evaporator 2 can directly fall into the groove 114, avoiding the condensed water from adhering to the back plate of the box 11.

[0080] Fig. 9 This is a schematic diagram of the structure of the box body (minus the box shell, drainage joint and drainage pipe) provided in this application.

[0081] like Figure 8 and Fig. 9As shown, in some embodiments, an extension portion 1141 may be provided on the groove 114. The extension portion 1141 is provided at the groove bottom of the groove 114. The extension portion 1141 extends toward the drain connector 3. A through hole 1142 is provided in the extension portion 1141. By providing the extension portion 1141, the contact area between the outer wall of the groove 114 and the drain connector 3 is increased, thereby improving the connection stability between the groove 114 and the drain connector 3.

[0082] Fig.10 This is a schematic diagram of the connection structure between the drainage joint and the box provided in this application. Fig.11 This is a schematic diagram of the structure of the drainage joint and drainage pipe provided in this application.

[0083] like Fig.10 As shown, in some embodiments of the present application, in order to realize the conversion between the groove 114 and the drain port, the box body 1 may include a drain connector 3. The drain connector 3 is connected to the bottom of the groove 114 and communicates with the through hole 1142. The drain connector 3 may be fixed to the outside of the box 11 by welding.

[0084] like Fig.10 and Fig.11 As shown, in some embodiments of the present application, the box body 1 may include a drain pipe 4. The drain pipe 4 is connected to an end of the drain joint 3 away from the groove 114. The drain pipe 4 is connected to the bottom of the drain joint 3.

[0085] In some embodiments of the present application, the inner surface of the drain connector 3 is configured as a slope inclined along the direction from the groove 114 to the drain pipe 4, so that the inner diameter of the end of the drain connector 3 close to the through hole 1142 is larger than the inner diameter of the end of the drain connector 3 close to the drain pipe 4, thereby achieving a transition between the large inner diameter of the drain groove and the small inner diameter of the drain pipe 4.

[0086] like Figure 6 , Fig.10 and Fig.11 As shown, in some embodiments of the present application, the drain connector 3 includes a connecting portion 31. The connecting portion 31 is disposed on a side of the drain connector 3 close to the groove 114 and is connected to the groove 114.
