Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the priority, under 35 U.S.C. § 119, of Chinese Patent Application CN 202520175610.9, filed January 23, 2025; the prior application is herewith incorporated by reference in its entirety. FIELD OF THE INVENTION

[0002] Embodiments of the present disclosure relate to the technical field of refrigeration appliances, and in particular, to a refrigeration appliance. BACKGROUND OF THE INVENTION

[0003] Household appliances are widely applied to daily life and work of people. For example, a refrigerator is used to store and keep an object in freshness, and a washing machine is used to clean an object. For a refrigeration appliance, a development trend of a current refrigeration appliance is to increase a volume to satisfy a large-capacity storage requirement of a user. However, a large-sized refrigeration appliance has a difficulty in construction when mounted to a home of the user. SUMMARY OF THE INVENTION

[0004] It is accordingly an object of the invention to provide a refrigeration appliance, which overcomes the hereinafore-mentioned disadvantages of and improves upon the heretofore-known appliances of this general type.

[0005] With the foregoing and other objects in view there is provided, in accordance with an embodiment of the invention, a refrigeration appliance, including a box body and doors. The box body defines at least one storage compartment. Each of the doors is movably connected to a front portion of the box body to open or close at least a part of the storage compartment. The box body is supported on a mounting surface through a bottom base. The bottom base includes a pair of supporting beams independent of each other and respectively supporting two sides of a bottom portion of the refrigeration appliance in a width direction or a depth direction. Each of the supporting beams is provided with a positioning portion. A bottom portion of the box body is provided with a fitting portion corresponding to the positioning portion. The positioning portion and the fitting portion position the supporting beam at the bottom portion of the box body through shape fitting and / or engagement, so that the supporting beam is mounted to the bottom portion of the box body when the box body is in a standing state.

[0006] Through this implementation, the pair of independent supporting beams are provided, so that no additional tool is needed during mounting the refrigeration appliance. The box body is slightly inclined to mount one of the supporting beams, and then the box body is inclined toward an other side to mount an other supporting beam, so that the bottom base may be conveniently and quickly mounted to the bottom portion of the box body. Further, the manner of matching the supporting beam and the box body enables that the supporting beams can be positioned on the box body when the refrigeration appliance is in the standing state. On one hand, at a home of the user, the refrigerator is impossible to be put down for mounting due to a space limitation, such as a kitchen. On the other hand, the refrigerator has a large size and an excessively heavy weight, and the refrigerator cannot be smoothly put down without a special turnover machine. Therefore, the refrigeration appliance can be mounted at a location of the user in a more convenient and space-saving manner.

[0007] Further, the refrigeration appliance is entirely elevated through the bottom base, and a gap between the bottom portion of the refrigeration appliance and the mounting surface is increased, to help radiate heat from the refrigeration appliance. Especially, when an embedded mounting manner is used for the refrigeration appliance, a heat dissipation effect of the refrigeration appliance is improved. The mounting surface may be, for example, a ground.

[0008] Optionally, in an extension direction, the supporting beam is provided with a first end and a second end that are opposite to each other. The positioning portion includes first positioning members disposed on the first end and a second positioning member disposed on the second end. The fitting portion includes first fitting members for matching the first positioning members and a second fitting member for matching the second positioning member. The first positioning members are in concave-convex fit with the first fitting members. The second positioning member is in concave-convex fit with the second fitting member. Therefore, the positioning member and the corresponding fitting member reliably position the supporting beams at the bottom portion of the box body through shape fitting. A concave-convex fitting manner further helps synchronously limit a relative movement between the box body and the supporting beams in the extension direction of the supporting beams as the supporting beams are mounted at the bottom portion of the box body, thereby preventing damage caused by unintended falling of the box body from the supporting beams during an entire movement of the refrigeration appliance in a state of being supported by the supporting beams, for example, during the refrigeration appliance being pushed into the cabinet. Further, manners of matching two ends of the supporting beam and the box body along the extension direction are opposite, which helps fool-proofing and ensures smooth completion of positioning connection of the box body in the standing state with the supporting beams.

[0009] Optionally, the positioning portion includes a positioning hole formed on the supporting beam. The positioning hole includes a first hole and a second hole that are in communication with each other. A hole size of the first hole is greater than a hole size of the second hole. The fitting portion enters the second hole through the first hole and is engaged on an edge of the second hole. Under a usage state of the refrigeration appliance, a direction in which the first hole points to the second hole is the same as a direction in which the refrigeration appliance enters a mounting position. Therefore, the calabash-shaped positioning hole is formed on the supporting surface of the supporting beam that is adapted to support the box body. The second hole having a relatively small hole size and the fitting portion are fitted with each other through engagement to ensure that the supporting beams are reliably positioned on the bottom portion of the box body. Further, the refrigeration appliance in the usage state keeps the fitting portion to be engaged with the edge of the second hole, so as to limit a relative movement between the box body and the supporting beam. Further, relative positions of the two holes of the positioning hole formed on the supporting surface are adapted to enable the following. After the pair of supporting beams are mounted to the bottom portion of the box body of the refrigeration appliance, during pushing the refrigeration appliance in a state of being supported on the bottom base backward into a cabinet to enable the refrigeration appliance to reach a mounting position embedded in the cabinet, the fitting portion is kept in a state of matching with the second hole having a relatively small hole size, so as to prevent that the fitting portion unexpectedly enters the first hole having a relatively large hole size to cause separation of the refrigeration appliance and the supporting beams.

[0010] During mounting, the box body is slightly inclined, the first hole of one of the supporting beams is first aligned with the fitting portion to enter the mounting position, the supporting beam is pushed in a direction in which the second holes point to the first hole until the fitting portion enters the second hole to complete mounting, and then the box body is inclined to an other side to mount an other supporting beam through a same method. Alternatively, during mounting, the entire refrigeration appliance may be horizontally lifted, two supporting beams of the pair of supporting beams are respectively placed at corresponding positions at the bottom portion of the box body, the refrigeration appliance is lowered, so that the fitting portion enters the first hole corresponding to the supporting beam to enter the mounting position, and then the refrigeration appliance is pushed in the direction in which the first hole points to the second hole until the fitting portion enters the second hole corresponding to the supporting beam. The entire mounting process is easy to operate.

[0011] Optionally, the positioning portion is fixed to the supporting beam through a first fixing member, and / or the fitting portion is fixed to the bottom portion of the box body through the first fixing member. Therefore, reliability of support and positioning of the bottom base for the refrigeration appliance is ensured. Further, the positioning portion may be the separation member and is additionally mounted to the supporting beam through the first fixing member. Similarly, the fitting portion may be the separation member and is additionally mounted to the box body through the first fixing member. The positioning portion and the fitting portion are independently manufactured and mounted to the supporting beam and the box body as accessories, so that the supporting beam and the box body may be configured and manufactured based on standard parts, thereby improving compatibility of the supporting beam and the box body. The user may select whether to mount the positioning portion and the fitting portion as required.

[0012] Optionally, the supporting beam includes a supporting surface facing the box body. The supporting surface is pressed to form punched hole structures. An edge of each of the punched hole structures is folded toward the box body to form the positioning portion. Therefore, an upward protrusion is directly formed on the supporting surface through punching, thereby reducing a quantity of parts and simplifying a mounting process. For example, a special-shaped hole may be first punched in the supporting surface, and then an outward flange is formed on the edge of a punched hole to serve as the positioning portion.

[0013] Optionally, the positioning portion includes snaps extending out from the supporting surface toward the box body. The fitting portion includes hooks disposed on the box body. The snaps are adapted to be snap-fitted with the hooks. Therefore, the supporting beams are reliably positioned at the bottom portion of the box body through engagement.

[0014] Optionally, the bottom base includes a plurality of supports respectively disposed on the pair of supporting beams, where each of the supporting beams is supported on the mounting surface through two supports disposed at an interval; and in a height direction of the refrigeration appliance, a relative distance between the supporting beam and each of the supports is adjustable. Therefore, the height of the refrigeration appliance to the mounting surface can be flexibly adjusted as required by adjusting the relative distance between the supporting beam and the support, thereby further improving a heat dissipation effect of the refrigeration appliance. In an application scenario in which the refrigeration appliance is mounted through embedding, the cabinet is usually provided with a skirting board. Therefore, the bottom base is mounted to the bottom portion of the refrigeration appliance, so that a sufficient space between a lower end of the door of the refrigeration appliance and the mounting surface is kept to mount the skirting board. Further, a distance between the bottom portion of the refrigeration appliance and the mounting surface is adjustable through matching of the supporting beam and the support, to adapt to skirting boards of different heights. Further, a vent is disposed on the skirting board. However, considering that a density and a size limitation of the vent on the skirting board may greatly increase ventilation resistance for cooling air discharging from the bottom portion of the refrigeration appliance, in this implementation, the distance between the bottom portion of the refrigeration appliance and the mounting surface is increased, and an area of the air outlet at the bottom portion of the refrigeration appliance is increased, to ensure that heat dissipation efficiency from the bottom portion of the refrigeration appliance meets the requirement.

[0015] Optionally, the supporting beam includes a supporting surface facing the box body and a pair of sidewalls extending from the supporting surface toward a direction away from the box body. A plurality of first through holes are formed at intervals on the pair of sidewalls in the height direction of the refrigeration appliance. Second through holes are formed on the support. A second fixing member passes through one of the plurality of first through holes and one of the second through holes to connect the support to the supporting beam. Therefore, the second fixing member is simultaneously passed through the first through hole and the second through hole to connect the bottom base as a whole.

[0016] Optionally, the relative distance between the supporting beam and the support is changed along with a change in a position of the first through hole, through which the second fixing member passes, formed on the sidewall. Therefore, the first through hole is provided at different heights. Based on a height that needs to be adjusted, the second fixing member is operated to pass through a first through hole at a corresponding height, so that the height is adjusted when the bottom base is assembled, and the mounting process is simplified.

[0017] Optionally, a plurality of rows of first through holes are formed at intervals on the pair of sidewalls in an extension direction. Each row of first through holes include a plurality of first through holes. Two adjacent rows of first through holes are staggered from each other in the height direction of the refrigeration appliance. Therefore, a quantity of first through holes located at different heights can be increased, more height options are available during mounting, and a finer granularity is enabled for an adjustment of the height from the bottom portion of the refrigeration appliance to the mounting surface. Further, the plurality of first through holes are disposed in a plurality of rows, which helps increase the quantity of the first through holes and prevent an excessively small space between adjacent first through holes from affecting a structural strength of the bottom base, thereby improving support reliability for the refrigeration appliance.

[0018] Optionally, the refrigeration appliance further includes an air blocking strip disposed at the bottom portion of the box body and configured to partition a space between the refrigeration appliance and the mounting surface into an air inlet channel and an air outlet channel. The air inlet channel is provided with a forward air inlet. The air outlet channel is provided with a forward air outlet. Therefore, a circulation circuit is formed at the bottom portion of the refrigeration appliance to promote heat dissipation.

[0019] Optionally, an area of the air outlet is adjusted along with an adjustment of a height of the refrigeration appliance to the mounting surface. Therefore, the area of the air outlet at the bottom portion of the refrigeration appliance is adjusted by adjusting the distance between the bottom portion of the refrigeration appliance and the mounting surface, thereby promoting heat dissipation.

[0020] Optionally, the air blocking strip extends from the bottom portion of the box body to the mounting surface. In this way, the air blocking strip extends to the mounting surface, and the bottom space of the refrigeration appliance is fully used, to improve a heat dissipation effect.

[0021] Optionally, the air blocking strip includes: a main body portion, extending from the bottom portion of the box body toward a direction away from the box body; and an extension portion, extending from a side of the main body portion away from the box body toward the mounting surface, where the extension portion is selected from a plurality of candidate extension portions based on a height of the refrigeration appliance to the mounting surface, and different candidate extension portions have different heights. Therefore, compatibility of the refrigeration appliance is improved. Specifically, the refrigeration appliance is pre-assembled with a standard part (namely, the main body portion) at delivery, and is adapted to a refrigerator mounted in a non-embedded manner or an embedded refrigerator in which the skirting board is not disposed in the cabinet. In addition, a plurality of candidate extension portions are additionally provided. The user may select a suitable extension portion to be mounted on the main body portion based on a height at which the refrigeration appliance is finally elevated through the bottom base, so that a height of an entire air blocking strip is adapted to the height between the refrigeration appliance and the mounting surface.

[0022] Optionally, the main body portion and the extension portion are mounted in different places. Therefore, the refrigeration appliance is more flexible in assembly, and mounting is more efficient at a location of a user.

[0023] Optionally, the bottom base may include a plurality of rollers. A plurality of supports are correspondingly disposed. The refrigeration appliance is supported on the mounting surface through the plurality of rollers. Therefore, the arrangement of the rollers can facilitate overall movement of the bottom base and the refrigeration appliance positioned and supported on the bottom base.

[0024] Optionally, the supporting beam is fixed through a limiting member along a rear end surface in an extension direction and a rear wall of the box body. Therefore, the limiting member is disposed to further limit the relative displacement between the bottom base and the refrigeration appliance. Further, the limiting member is disposed on a rear side of the refrigeration appliance. The side is usually invisible to the user in a usage state of the refrigeration appliance, which helps keep a beautiful and concise appearance that is visible to the user in the usage state of the refrigeration appliance.

[0025] Optionally, the limiting member is fixed to the rear wall of the box body through fasteners. The fasteners are also used as fasteners between a rear cover plate of a compressor compartment of the refrigeration appliance and lamb leg-shaped supporting members. Therefore, a reduction in the quantity of parts is facilitated.

[0026] Other features which are considered as characteristic for the invention are set forth in the appended claims.

[0027] Although the invention is illustrated and described herein as embodied in a refrigeration appliance, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.

[0028] The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings. BRIEF DESCRIPTION OF THE FIGURES

[0049] In order to make the foregoing objectives, characteristics, and advantages of the present disclosure clearer and easier to understand, specific embodiments of the present disclosure are described in detail below with reference to drawings.

[0050] Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen a perspective view of a refrigeration appliance 1 according to a first embodiment of the present disclosure.

[0051] The refrigeration appliance 1 may be a refrigerator, a freezer, a wine cabinet, or the like. FIG. 1 is exemplarily shown by using a cross-door refrigerator as an example. In an actual application, this implementation may be applied to a single-door refrigerator, or may be applied to a refrigerator having left and right doors and a three-door refrigerator in various forms such as a French open-door refrigerator and an open-door refrigerator.

[0052] For ease of description, in this implementation, a width direction of the refrigeration appliance 1 is denoted as an x direction, a depth direction is denoted as a y direction, and a height direction is denoted as a z direction. In this implementation, a front-rear direction refers to the y direction and an opposite direction thereof, where a front portion or a front side refers to a direction facing a user during use of the refrigeration appliance 1, and a rear or a rear side refers to a direction facing away from the user during use of the refrigeration appliance 1. In this implementation, an up-down direction refers to the z direction and an opposite direction thereof, where an upward portion or an upper side or a top portion refers to a direction that is more up along a gravity direction during use of the refrigeration appliance 1, and a downward portion or a lower side or a bottom portion refers to a direction that contacts or is closest to a mounting surface during use of the refrigeration appliance 1. The mounting surface may be, for example, a ground, or may be a bottom wall of a cabinet 3 (as shown in FIG. 15).

[0053] The refrigeration appliance 1 in this implementation may arrive at a location of a user after being shipped at delivery, for example, arrive at a home of a user. After being mounted at the location of the user, the refrigeration appliance 1 may enter a usage state for the user to use.

[0054] Specifically, referring to FIG. 1, the refrigeration appliance 1 may include a box body 10 and doors 11. The box body 10 defines at least one storage compartment. The door 11 is movably connected to a front portion of the box body 10 to open or close at least a part of the storage compartment. Using the refrigerator as an example, the storage compartment may be, for example, a freezing compartment, a refrigerating compartment, a temperature-changing chamber, or the like.

[0055] The box body 10 has a top portion 10b and a bottom portion 10a that are opposite to each other in the z direction. It may be understood that the top portion 10b of the box body 10 corresponds to a top portion of the refrigeration appliance 1, and the bottom portion 10a of the box body 10 corresponds to a bottom portion of the refrigeration appliance 1.

[0056] Further, the box body 10 may be supported on the mounting surface through a bottom base 2. For example, the bottom base 2 is placed on the mounting surface, and the bottom portion 10a of the box body 10 is supported on the bottom base 2. The bottom base 2 may include a plurality of independent members. The plurality of independent members are respectively supported at different positions of the bottom portion 10a of the box body 10. Specifically, 2 independent members may be disposed. As shown in FIG. 1, the two independent members are respectively supported on two sides of the bottom portion 10a of the box body 10 in the x direction. Each independent member has a same structure. Therefore, a specific structure of the bottom base 2 in this embodiment is exemplarily illustrated by using a single independent member as an example.

[0057] Further, the bottom base 2 may include a pair of supporting beams 21 independent of each other and respectively support two sides of the bottom portion of the refrigeration appliance 1 in a width direction or a depth direction. The pair of supporting beams 21 respectively belong to two independent members. Referring to FIG. 1 to FIG. 5, each supporting beam 21 extends in the y direction, and the pair of supporting beams 21 respectively support two sides of the bottom portion 10a of the box body 10 in the x direction. Therefore, a relatively small structure of the bottom base 2 can be seen in the front of the refrigeration appliance 1, which helps improve an aesthetic appearance of the refrigeration appliance 1. Further, the refrigeration appliance 1 is entirety elevated by the bottom base 2, and a gap between the bottom portion 10a of the box body 10 and the mounting surface is increased, to help heat dissipation for the refrigeration appliance 1. The pair of supporting beams 21 respectively disposed on two opposite sides of the bottom portion 10a of the box body 10a in the x direction can reserve an opening facing forward to expose the gap, helping heat dissipation for the bottom portion of the refrigeration appliance 1 through the gap. A heat dissipation effect for the refrigeration appliance 1 is significantly improved, especially when the refrigeration appliance 1 is mounted through embedding.

[0058] Further, referring to FIG. 1 to FIG. 6, each of the supporting beams 21 is provided with a positioning portion 22. The bottom portion 10a of the box body 10 is provided with a fitting portion 12 corresponding to the positioning portion 22. The positioning portion 22 and the fitting portion 12 position the supporting beam 21 at the bottom portion 10a of the box body 10 through shape fitting and / or engagement, so that the supporting beam 21 is mounted to the bottom portion 10a of the box body 10 when the box body 10 is in a standing state.

[0059] For example, referring to FIG. 2 and FIG. 3, the pair of independent supporting beams 21 are provided, so that no additional tool is needed during mounting the refrigeration appliance 1. The box body 10 is slightly inclined to mount one of the supporting beams 21. After the positioning portion 22 of the supporting beam 21 and the fitting portion 12 on a corresponding side of the bottom portion 10a of the box body 10 are shape-fitted and / or engaged, then the box body 10 is inclined to an other side, and an other supporting beam 21 is mounted in a same manner, so that the bottom base 2 can be conveniently and quickly mounted to the bottom portion 10a of the box body 10 to form the state shown in FIG. 1. Further, the manner of matching the supporting beam 21 and the box body 10 based on the positioning portion 22 and the fitting portion 12 enables that the supporting beams 21 can be positioned on the box body 22 when the refrigeration appliance 1 is in the standing state. On one hand, at a home of the user, the refrigerator is impossible to be put down for mounting due to a space limitation, such as a kitchen. On the other hand, the refrigerator has a large size and an excessively heavy weight, and the refrigerator cannot be smoothly put down without a special turnover machine. Therefore, the refrigeration appliance 1 can be mounted at a location of a user in a more convenient and space-saving manner.

[0060] In a specific implementation, referring to FIG. 1 to FIG. 9, the supporting beam 21 may be provided with a first end 21a and a second end 21b that are opposite to each other in an extension direction. When the pair of supporting beams 21 are respectively disposed on two opposite sides of the bottom portion 10a of the box body 10 in the x direction, the first end 21a is located behind the second end 21b in the y direction.

[0061] Further, the positioning portion 22 may include first positioning members 221 disposed on the first end 21a and a second positioning member 222 disposed on the second end 21b. The fitting portion 12 includes first fitting members 121 for matching the first positioning members 221 and a second fitting member 122 for matching the second positioning member 222. The first positioning members 221 are in concave-convex fit with the first fitting members 121. The second positioning member 222 is in concave-convex fit with the second fitting member 122. It should be noted that although the first embodiment shown in FIG. 1 to FIG. 9 is exemplarily illustrated by using an example in which the second end 21b is located in front of the first end 21a, the first end 21a may be located in front of the second end 21b in an actual application. Correspondingly, the supporting beam 21 and the box body 10 are in a convex-and-convex fit at the front and a convex-and-convex fit at the rear in the y direction.

[0062] Therefore, the positioning member 22 and the corresponding fitting member 12 reliably position the supporting beams 21 at the bottom portion 10a of the box body 10 through shape fitting. A concave-convex fitting manner further helps synchronously limit a relative movement between the box body 10 and the supporting beams 21 in the extension direction of the supporting beams 21 as the supporting beams 21 are mounted at the bottom portion 10a of the box body 10, thereby preventing damage caused by unintended falling of the box body 10 from the supporting beams 21 during an entire movement of the refrigeration appliance 1 in a state of being supported by the supporting beams 21, for example, during the refrigeration appliance 1 being pushed into the cabinet 3. Further, manners of matching two ends of the supporting beam 21 and the box body 10 along the extension direction are opposite, which helps fool-proofing and ensures smooth completion of positioning connection of the box body 10 in the standing state with the supporting beams 21.

[0063] In some embodiments, still referring to FIG. 3 to FIG. 7, the positioning portion 22 may include a positioning hole 223 formed on the supporting beam 21. Specifically, the supporting beam 21 may include a supporting surface 211 that faces the box body 10. The refrigeration appliance 1 is supported on the supporting surface 211 in the usage state. A through hole may be formed on the supporting surface 211 close to the second end 21b to form the positioning hole 223.

[0064] Further, the fitting portion 12 may include a second fitting member 122 disposed on the bottom portion 10a of the box body 10. For example, the second fitting member 122 may be a screw that is fixed to the bottom portion 10a of the box body 10. A tip of the screw is inserted into the bottom portion 10a of the box body 10 and is fixed to the box body 10. An expansion portion of the screw extends out from the bottom portion 10a of the box body 10 toward the bottom base 2.

[0065] Further, the positioning hole 223 may include a first hole 224 and a second hole 225 that are in communication with each other. A hole size of the first hole 224 is greater than a hole size of the second hole 225. For example, the positioning hole 223 may be in a calabash shape. A portion of the calabash-shaped hole having a relatively large hole size forms the first hole 224, and a portion having a relatively small hole size forms the second hole 225.

[0066] Further, the fitting portion 12 (for example, the second fitting member 122) enters the second hole 225 through the first hole 224 and is engaged with an edge of the second hole 225. In other words, a size of the expansion portion is smaller than the hole size of the first hole 224 and larger than the hole size of the second hole 225. Therefore, the expansion portion of the second fitting member 122 passes through the first hole 224 to the second hole 225, and then is engaged with an edge of the second hole 225, to implement engagement between the second fitting member 122 and the positioning portion 22 (for example, the second positioning member 222).

[0067] Therefore, the calabash-shaped positioning hole 223 is formed on the supporting surface 211 of the supporting beam 21 that is adapted to support the box body 10. The second hole 225 having a relatively small hole size and the fitting portion 12 are fitted with each other through engagement to ensure that the supporting beams 21 are reliably positioned on the bottom portion 10a of the box body 10. Further, the refrigeration appliance 1 in the usage state keeps the fitting portion 12 to be engaged with the edge of the second hole 225, so as to limit a relative movement between the box body 10 and the supporting beam 21, thereby preventing the refrigeration appliance 1 from unexpectedly falling from the bottom base 2 during daily use to cause damage.

[0068] In some embodiments, in the usage state of the refrigeration appliance 1, a direction in which the first hole 224 points to the second hole 225 is a same direction as the direction in which the refrigeration appliance 1 enters a mounting position. The mounting position refers to a position at which the refrigeration appliance 1 is embedded in the cabinet 3, as shown in FIG. 14.

[0069] Specifically, referring to FIG. 4 and FIG. 5, the first hole 224 may be located in front of the second hole 225 in the y direction, so that relative positions of the two holes of the positioning hole223 formed on the supporting surface 211 are adapted to enable the following. After the pair of supporting beams 21 are mounted to the bottom portion 10a of the box body 10 of the refrigeration appliance 1, during pushing the refrigeration appliance 1 in a state of being supported on the bottom base 2 backwards into a cabinet 3 to enable the refrigeration appliance 1 to reach a mounting position, the fitting portion 12 is kept in a state of matching with the second hole 225 having a relatively small hole size, so as to prevent that the fitting portion 12 unexpectedly enters the first hole 224 having a relatively large hole size to cause separation of the refrigeration appliance 1 and the supporting beams 21.

[0070] In a non-limiting example, when the refrigeration appliance 1 arrives at the location of the user for mounting, the box body 10 is slightly inclined (as shown in FIG. 2 and FIG. 3), the first hole 224 of one of the supporting beams 21 is first aligned with the fitting portion 12 (for example, an expansion portion of a screw) to enter the mounting position, and the supporting beam 21 is pushed in a direction in which the second hole 225 points to the first hole 224 (namely, the y direction) until the expansion portion enters the second hole 225 to complete mounting. Then, the box body 10 is inclined to an other side, and an other supporting beam 21 is mounted through the same method. The mounting of the refrigeration appliance 1 is completed, and the refrigeration appliance is put into the usage state as shown in FIG. 1. Further, if the refrigeration appliance 1 needs to be mounted through embedding, the refrigeration appliance 1 supported on the bottom base 2 may be pushed. In this case, the refrigeration appliance 1 and the bottom base 2 entirely move on the mounting surface under an action of rollers 26 until the refrigerating device is pushed into the cabinet 3. At this point, the refrigeration appliance 1 is at the mounting position, as shown in FIG. 14.

[0071] In another non-limiting example, when the refrigeration appliance 1 arrives at the location of the user for mounting, the entire refrigeration appliance 1 may be horizontally lifted, the pair of supporting beams 21 are respectively placed at corresponding positions of the bottom portion 10a of a box body 10, and the refrigeration appliance 1 is lowered, so that the fitting portion 12 (for example, the expansion portion of the screw) enters the first hole 224 of the corresponding supporting beam 21 to enter the mounting position, and then the refrigeration appliance 1 is pushed in the direction (that is, an opposite direction of the y direction) in which the first hole 224 points to the second hole 225 until the expansion portion enters the second hole 225 of the corresponding supporting beam 21. The whole mounting process is easy to operate. Similarly, if the refrigeration appliance 1 needs to be mounted through embedding, the refrigeration appliance 1 supported on the bottom base 2 may be pushed. In this case, the refrigeration appliance 1 and the bottom base 2 entirely move on the mounting surface under an action of rollers 26 until the refrigerating device is pushed into the cabinet 3. At this point, the refrigeration appliance 1 is at the mounting position, as shown in FIG. 14.

[0072] In a specific implementation, still referring to FIG. 3 to FIG. 5, the supporting surface 211 may be pressed to form punched hole structures 212. An edge of each of the punched hole structures 212 is folded toward the box body 10 to form the positioning portion 22.

[0073] Specifically, compared with the foregoing positioning hole 223 that is adapted to form a concave structure on the supporting beam 21 to match with the fitting portion 12 (for example, the second fitting member 122) that forms a convex structure on the box body 10, the punched hole structure 212 in this embodiment is adapted to form the convex structure on the supporting beam 21 to match with the fitting portion 12 (for example, the first fitting member 121) that forms the concave structure on the box body 10.

[0074] For example, a special-shaped hole may be first punched in the supporting surface 211, and then an outward flange is formed on the edge of a punched hole to serve as the positioning portion 22, which specifically may be the first positioning member 221.

[0075] Further, the first fitting member 121 includes a groove disposed at the bottom portion 10a of the box body 10. The groove is open toward the supporting beam 21 to receive the flange of the punched hole structure 212.

[0076] Further, a plurality of punched hole structures 212 may be disposed on a single supporting surface 211. The plurality of punched hole structures 212 are disposed at intervals in the extension direction (for example, the y direction) of the supporting beam 21 and are closer to the first end 21a than to the second end 21b. Correspondingly, a plurality of first fitting members 121 may also be disposed at intervals in the y direction. The plurality of first fitting members 121 are in a one-to-one correspondence with the plurality of punched hole structures 212. In the figure, an exemplary illustration is provided by using 2 punched hole structures 212 and 2 first fitting members 121 as an example.

[0077] Therefore, an upward protrusion is directly formed on the supporting surface 211 through punching, thereby reducing a quantity of parts and simplifying a mounting process.

[0078] In some embodiments, referring to FIG. 6, FIG. 8, and FIG. 9, the refrigeration appliance 1 may include a compressor compartment configured to accommodate a compressor. The compressor compartment may include a rear cover plate 16 of the compressor compartment defining a rear surface, two lamb leg-shaped supporting members 17 disposed opposite to each other in an x direction, and a support plate 18 connected to the lamb leg-shaped supporting members 17. The support plate 18 is configured to support the compressor. Further, the first fitting member 121 may reuse an original groove structure on the lamb leg-shaped supporting member 17, as shown in FIG. 6. Therefore, an existing structure of the refrigeration appliance 1 can be fully used to reduce the quantity of parts.

[0079] FIG. 10 is a partial exploded view of a bottom portion of a refrigeration appliance 1 according to a second embodiment of the present disclosure. Only a difference between the second embodiment and the first embodiment shown in FIG. 1 to FIG. 9 is mainly described herein.

[0080] Specifically, referring to FIG. 10 to FIG. 12, a difference between the refrigeration appliance 1 in the second embodiment and the refrigeration appliance 1 in the first embodiment shown in FIG. 1 to FIG. 9 mainly includes: the positioning portion 22 is fixed to the supporting beam 21 through the first fixing member 23, and / or the fitting portion 12 is fixed to the bottom portion 10a of the box body 10 through the first fixing member 23. In other words, at least one of the positioning portion 22 and the fitting portion 12 is an independent member and is fixed to a corresponding component (namely, the supporting beam 21 or the box body 10) through the first fixing member 23.

[0081] For example, the first positioning member 221 may be a separation member. An assembly hole 227 is formed on the supporting surface 211 of the supporting beam 21 close to the first end 21a. The first fixing member 23 passes through the first positioning member 221 and the assembly hole 227 to fix the first positioning member 221 to the supporting beam 21. Correspondingly, the first fitting member 121 may reuse a recess structure on the lamb leg-shaped supporting member 17 that is originally used to mount a wheel. As shown in FIG. 6, the recess structure may be located, in the y direction, on the rear of two grooves on the lamb leg-shaped supporting member 17 that are adapted to form the first fitting members 121 in the foregoing first embodiment. The first positioning member 221 is in concave-convex fit with the first fitting member 121.

[0082] For another example, the second fitting member 122 may be a separation member and is fixed to a region corresponding to the second end 21b of the bottom portion 10a of the box body 10 through the first fixing member 23. Correspondingly, the second positioning member 222 may be a through hole formed on a supporting surface 211 close to the second end 21b, so as to receive the second fitting member 122 protruding downward from the bottom portion 10a of the box body 10. The second positioning member 222 is in concave-convex fit with the second fitting member 122.

[0083] Therefore, reliability of support and positioning of the bottom base 2 for the refrigeration appliance 1 is ensured. Further, the positioning portion 22 may be the separation member and is additionally mounted to the supporting beam 21 through the first fixing member 23. Similarly, the fitting portion 12 may be the separation member and is additionally mounted to the box body 10 through the first fixing member 23. The positioning portion 22 and the fitting portion 12 are independently manufactured and mounted to the supporting beam 21 and the box body 10 as accessories, so that the supporting beam 21 and the box body 10 may be configured and manufactured based on standard parts, thereby improving compatibility of the supporting beam 21 and the box body 10. The user may select whether to mount the positioning portion 22 and the fitting portion 12 as required.

[0084] In some embodiments, still referring to FIG. 12, two first fixing members 23 configured to fix the first positioning member 221 may be disposed at intervals from front to rear in the y direction. Accordingly, two assembly holes 227 that are disposed at intervals in the y direction are correspondingly formed on the supporting surface 211.

[0085] Further, two assembly holes 227 disposed from front to rear in the y direction are denoted as a row of assembly holes 227. Two rows of assembly holes 227 may be disposed on the supporting surface 211 in parallel in the x direction. Therefore, the same supporting beam 21 may be compatible with left and right lamb leg-shaped supporting members 17.

[0086] For example, when the supporting beam 21 is mounted to a right side of the bottom portion 10a of the box body 10 from the perspective of FIG. 10, the first fixing member 23 may be successively passed through the first positioning member 221 and the row of assembly holes 227 that are rightward based on the perspective of FIG. 12, to fix the first fixing member 23 to a rightward side of a central axis of the supporting surface 211, as shown in FIG. 11. Therefore, the first positioning member 221 can match with the first fitting member 121 disposed on the lamb leg-shaped supporting member 17 on the right side of the box body 10 based on the perspective of FIG. 10, to reliably mount the supporting beam 21 to the right side of the bottom portion 10a of the box body 10.

[0087] For another example, when the supporting beam 21 is mounted to a left side of the bottom portion 10a of the box body 10 from the perspective of FIG. 10, the first fixing member 23 may be successively passed through the first positioning member 221 and the row of assembly holes 227 that are leftward based on the perspective of FIG. 12, to fix the first fixing member 23 to a rightward side of the central axis of the supporting surface 211. Therefore, the first positioning member 221 can match with the first fitting member 121 disposed on the lamb leg-shaped supporting member 17 on the left side of the box body 10 based on the perspective of FIG. 10, to reliably mount the supporting beam 21 to the left side of the bottom portion 10a of the box body 10.

[0088] In some embodiments, the first fixing member 23 may be a screw.

[0089] In a specific implementation, referring to FIG. 10 to FIG. 13, a difference between the bottom base 2 of the second embodiment and the bottom base 2 of the foregoing first embodiment further includes: the positioning portion 22 may include a snap 226 extending from the supporting surface 211 toward the box body 10. Correspondingly, the fitting portion 12 may include a hook 123 disposed on the box body 10. The snap 226 is adapted to be snap-fitted with the hook 123. Therefore, the fitting portion 12 and the positioning portion 22 may be engaged through snap-fitting connection, so as to reliably position the supporting beam 21 on the bottom portion 10a of the box body 10 through engagement.

[0090] Further, the hook 123 may be disposed on the lamb leg-shaped supporting member 17, and specifically, may be an existing structure on the lamb leg-shaped supporting member 17, or may be a newly added structure to match with the snap 226. In some embodiments, the hook 123 may be disposed between two first fitting members 121 in the foregoing first embodiment.

[0091] Further, two hooks 123 may be disposed on the lamb leg-shaped supporting member 17 from front to rear in the y direction. Correspondingly, two snaps 226 are disposed on the supporting surface 211 from front to rear in the y direction. The two snaps 226 disposed from front to rear in the y direction are denoted as a row of snaps 226. Two rows of snaps 226 may be disposed on the supporting surface 211 in parallel in the x direction. Therefore, a same supporting beam 21 may be compatible with left and right lamb leg-shaped supporting members 17. When the supporting beams 21 support different sides of the box body 10 in the x direction, different rows of snaps 226 are snap-fitted with the hooks 123.

[0092] In a specific implementation, in a common embodiment of the first embodiment and the second embodiment, referring to FIG. 3, FIG. 4, and FIG. 7 to FIG. 12, the bottom base 2 may include a plurality of supports 24 respectively disposed on the pair of supporting beam 21. Each supporting beam 21 is supported on the mounting surface through two supports 24 disposed at intervals. For example, each supporting beam 21 may be supported on the mounting surface through two supports 24 that are disposed at intervals in the extension direction (for example, the y direction) of the supporting beam.

[0093] Further, the bottom base 2 may include a plurality of rollers 26. A plurality of supports 24 are correspondingly disposed. The refrigeration appliance 1 is supported on the mounting surface through the plurality of rollers 26. The arrangement of the rollers 26 can facilitate overall movement of the bottom base 2 and the refrigeration appliance 1 positioned and supported on the bottom base. In some embodiments, each support 24 is supported on the mounting surface through a roller 26. For example, a third through hole 262 may be formed on the support 24. A pin 261 is passed through a rotation axis of the roller 26 and the third through hole 262 to rotatably connect the roller 26 to the support 24.

[0094] Further, a relative distance between the supporting beam 21 and the support 24 in the z direction is adjustable. Therefore, the height of the refrigeration appliance 1 to the mounting surface can be flexibly adjusted as required by adjusting the relative distance between the supporting beam 21 and the support 24, thereby further improving a heat dissipation effect of the refrigeration appliance 1.

[0095] Referring to FIG. 14, in an application scenario in which the refrigeration appliance 1 is mounted through embedding, the cabinet 3 is usually provided with a skirting board 31. Therefore, the bottom base 2 is mounted to the bottom portion of the refrigeration appliance 1, so that a sufficient space between a lower end of the door 11 of the refrigeration appliance 1 and the mounting surface is kept to mount the skirting board 31, thereby preventing that an existence of the skirting board 31 interferes with opening or closing of the door 11. For example, the relative distance between the supporting beam 21 and the support 24 in the z direction is adjusted, to ensure that the height from the bottom portion of the refrigeration appliance 1 to the mounting surface is not less than a height of the skirting board 31 in the usage state of the refrigeration appliance 1. Further, a distance between the bottom portion of the refrigeration appliance 1 and the mounting surface is adjustable through matching of the supporting beam 21 and the support 24, to adapt to skirting boards 31 of different heights.

[0096] In a variation, one supporting beam 21 may be provided with one support 24. A length of the support 24 extending along the y direction is substantially equal to a length of the supporting beam 21 extending along the y direction. Further, one roller 26 is respectively connected to two ends of the support 24 in the extension direction.

[0097] Alternatively, one supporting beam 21 may be provided with three supports 24, which are respectively located at a front end, a middle end, and a rear end of the supporting beam 21 in the extension direction. Further, each support 24 is provided with one roller 26.

[0098] In a specific implementation, still referring to FIG. 3, FIG. 4, FIG. 7, FIG. 9, and FIG. 10 to FIG. 12, the supporting beam 21 may include a supporting surface 211 facing the box body 10 and a pair of sidewalls 213 extending from the supporting surface 211 to a direction away from the box body 10. A plurality of first through holes 214 are formed on the pair of sidewalls 213 at intervals in the z direction. Correspondingly, a second through hole 241 may be formed on the support 24. One of the plurality of first through holes 214 and the second through hole 241 are both passed through by a second fixing member 25 to connect the support 24 to the supporting beam 21. Therefore, the second fixing member 25 is passed through both the first through hole 214 and the second through hole 241 to connect the bottom base 2 as a whole.

[0099] Specifically, the support 24 may include a bottom connection wall disposed opposite to the supporting surface 211. A through hole is disposed on the bottom connection wall to avoid the roller 26. Further, the support 24 may further include a pair of side connection walls extending from the bottom connection wall toward the supporting beam 21. The pair of side connection walls respectively correspond to a pair of sidewalls 213. Each sidewall 213 is located on an outer side of a corresponding side connection wall in the x direction.

[0100] Further, the second through hole 241 is formed on each of the pair of side connection walls. A plurality of first through holes 214 are correspondingly formed on the pair of sidewalls 213. For example, the first through hole 214 may be a through hole with a smooth hole wall. The second through hole 241 may be a threaded hole. The second fixing member 25 may be a screw. The screw is fixed through insertion into the threaded hole through the first through hole 214.

[0101] Further, the relative distance between the supporting beam 21 and the support 24 is changed along with a change in a position of the first through hole 214, through which the second fixing member 25 passes, formed on the sidewall 213. For example, if the first through hole 214 through which the second fixing member 25 passes is closer to the supporting surface 211, the relative distance between the supporting beam 21 and the support is smaller, and the bottom portion of the refrigeration appliance 1 is correspondingly closer to the mounting surface.

[0102] Therefore, the first through hole 214 is provided at different heights. Based on a height that needs to be adjusted, the second fixing member 25 is operated to pass through a first through hole 214 at a corresponding height, so that the height is adjusted when the bottom base 2 is assembled, and the mounting process is simplified. Further, the relative distance between the supporting beam 21 and the support 24 may be adjusted before the bottom base 2 is mounted to the bottom portion 10a of the box body 10, so that the height of the refrigeration appliance 1 to the mounting surface can be adjusted in a more energy-saving manner.

[0103] In some embodiments, the second through holes 241 may be symmetrically formed on a pair of side connection walls.

[0104] In some embodiments, referring to FIG. 10 to FIG. 12, two second through holes 241 may be formed at intervals in the y direction for each side connection wall. Correspondingly, two rows of first through holes 214 are respectively formed at intervals in the y direction on each sidewall 213 close to the first end 21a and the second end 21b, where each row of first through holes 214 include a plurality of first through holes 214 disposed at intervals in the z direction.

[0105] In some embodiments, referring to FIG. 4, FIG. 7, and FIG. 9, for each side connection wall, two groups of second through holes 241 may be formed at intervals in the y direction, where each group of second through holes 241 includes two adjacent second through holes 241 in the y direction. Correspondingly, two groups of first through holes 214 are respectively formed at intervals in the y direction on each sidewall 213 close to the first end 21a and the second end 21b, where each group of first through holes 214 includes two adjacent rows of first through holes 214 in the y direction, and each row of first through holes 214 include a plurality of first through holes 214 disposed at intervals in the z direction.

[0106] Further, for each group of first through holes 214, two adjacent rows of first through holes 214 included in the group of first through holes 214 are staggered relative to each other in the z direction. Therefore, a quantity of first through holes 214 located at different heights can be increased, more height options are available during mounting, and a finer granularity is enabled for an adjustment of the height from the bottom portion of the refrigeration appliance 1 to the mounting surface. Further, the plurality of first through holes 214 included in each group of first through holes 214 are disposed in a plurality of rows, which helps increase the quantity of the first through holes 214 and prevent an excessively small space between adjacent first through holes 214 from affecting a structural strength of the bottom base 2, thereby improving support reliability for the refrigeration appliance 1.

[0107] In some embodiments, for each row of first through holes 214, a spacing between adjacent first through holes 214 in the row of first through holes 214 may be 10 millimeters.

[0108] FIG. 15 is a schematic diagram of mounting a refrigeration appliance 1 in a cabinet 3 according to a third embodiment of the present disclosure. During mounting at a location of a user, after the bottom base 2 shown in the foregoing first embodiment or the second embodiment is mounted at a bottom portion of the refrigeration appliance 1, the refrigeration appliance 1 supported by the bottom base 2 is pushed into the cabinet 3 to implement embedding mounting. Then, a skirting board 31 is mounted in the front of the bottom portion of the refrigeration appliance 1.

[0109] Specifically, referring to FIG. 1, FIG. 2, FIG. 8, and FIG. 15 to FIG. 19, the refrigeration appliance 1 may further include an air blocking strip 13 disposed at the bottom portion 10a of the box body 10 and configured to divide a space between the refrigeration appliance 1 and the mounting surface into an air inlet channel 14 and an air outlet channel 15. Further, the air inlet channel 14 is provided with a forward air inlet 141, and the air outlet channel 15 is provided with a forward air outlet 151.

[0110] For example, the air blocking strip 13 may extend substantially in the y direction, to divide a space defined by the refrigeration appliance 1, the mounting surface, and the bottom base 2 into the air inlet channel 14 and the air outlet channel 15 from left to right in the x direction. Further, the air inlet 141 and the air outlet 151 are respectively provided in the compressor compartment, so that a circulation circuit communicating the compressor compartment and the outside is formed at the bottom portion of the refrigeration appliance 1 to promote heat dissipation. External gas (for example, cool air) enters the air inlet channel 14 through a ventilation hole formed on the skirting board 31, enters the compressor compartment through the air inlet 141, and air (for example, hot air) inside the compressor compartment enters the air outlet channel 15 through the air outlet 151 and then is exhausted through the ventilation hole formed on the skirting board 31.

[0111] Considering a density and a size limitation of the vent on the skirting board 31 may greatly increase ventilation resistance for cooling air discharging from the bottom portion of the refrigeration appliance 1, in this implementation, the distance between the bottom portion of the refrigeration appliance 1 and the mounting surface is increased through the bottom base 2 having an adjustable height, and an area of the air outlet 151 at the bottom portion of the refrigeration appliance 1 is increased, to ensure that heat dissipation efficiency from the bottom portion of the refrigeration appliance 1 meets the requirement.

[0112] Further, the area of the air outlet 151 is adjusted along with an adjustment of a height of the refrigeration appliance 1 to the mounting surface. For example, a larger relative distance between the supporting beam 21 and the support 24 indicates a larger height of the refrigeration appliance 1 to the mounting surface, thereby enabling a larger area of the air outlet 151. Therefore, the area of the air outlet 151 at the bottom portion of the refrigeration appliance 1 is adjusted by adjusting the distance between the bottom portion of the refrigeration appliance 1 and the mounting surface, thereby promoting heat dissipation. Similarly, as the height of the refrigeration appliance 1 to the mounting surface is adjusted, the area of the air inlet 141 is also adjusted accordingly.

[0113] In a specific implementation, the air blocking strip 13 may extend from the bottom portion 10a of the box body 10 to the mounting surface. Specifically, that the air blocking strip 13 extends to the mounting surface means that the air blocking strip 13 abuts against the mounting surface or is in virtual contact with the mounting surface, or a gap between the air blocking strip and the mounting surface may be negligible. In this way, the air blocking strip 13 extends to the mounting surface, and the bottom space of the refrigeration appliance 1 is fully used to form the air inlet channel 14 and the air outlet channel 15, thereby improving a heat dissipation effect.

[0114] Further, a height of the air blocking strip 13 extending from the bottom portion 10a of the box body 10 toward the mounting surface may be determined based on the height from the bottom portion 10a of the box body 10 to the mounting surface. Therefore, that the air blocking strip 13 can fully extend to the mounting surface after the refrigeration appliance 1 supported on the bottom base 2 is embedded in the cabinet 3 is facilitated to be ensured.

[0115] In some embodiments, referring to FIG. 17 to FIG. 19, the air blocking strip 13 may include: a main body portion 131, extending from the bottom portion 10a of the box body 10 toward a direction away from the box body 10; and an extension portion 132, extending from a side of the main body portion 131 away from the box body 10 toward the mounting surface.

[0116] Further, the extension portion 132 is selected from a plurality of candidate extension portions based on a height of the refrigeration appliance 1 to the mounting surface, and different candidate extension portions have different heights. The height of the candidate extension portion is a distance between a side at which the candidate extension portion is connected to the main body portion 131 and a side facing the mounting surface.

[0117] Therefore, compatibility of the refrigeration appliance 1 is facilitated to improve. Specifically, the refrigeration appliance 1 is pre-assembled with a standard part (namely, the main body portion 131) at delivery, and may be adapted to a refrigerator mounted in a non-embedded manner or an embedded refrigerator in which the skirting board 31 is not disposed in the cabinet 3. In addition, a plurality of candidate extension portions are additionally provided. The user may select a suitable candidate extension portion as the extension portion 132 to be mounted on the main body portion 131 based on a height at which the refrigeration appliance 1 is finally elevated through the bottom base 2, so that a height of an entire air blocking strip 13 is adapted to the height between the refrigeration appliance 1 and the mounting surface.

[0118] Further, the main body portion 131 and the extension portion 132 may have different mounting sites. Therefore, the refrigeration appliance 1 is more flexible in assembly, and mounting is more efficient at the location of the user.

[0119] In a typical application scenario, the main body portion 131 may be fixed at the bottom portion 10a of the box body 10 through screwing when the refrigeration appliance 1 is delivered. After the refrigeration appliance 1 is delivered to the user, a candidate extension portion of a suitable height is selected as the extension portion 132 based on a height of the skirting board 31 of the cabinet 3. On the other hand, the relative distance between the support24 and the supporting surface 211 is adjusted through the second fixing member 25 passing through the first through hole 214 of an appropriate height, to ensure that the height from the supporting surface 211 to the mounting surface is not less than the height of the skirting board 31.

[0120] Then, the refrigeration appliance 1 is inclined to one side in the x direction to mount the bottom base 2 on one side, and then the refrigeration appliance is inclined to an other side to mount the bottom base 2 on an other side. During this period, the extension portion 132 is adhered to the main body portion 131 through a double-sided tape, as shown in FIG. 17. In this case, the refrigeration appliance 1 shown in FIG. 8 and FIG. 19 can be mounted.

[0121] Next, the refrigeration appliance 1 supported on the bottom base 2 is pushed into the cabinet 3 through the roller 26, as shown in FIG. 16. Finally, the skirting board 31 is mounted to obtain the structure shown in FIG. 15.

[0122] In a variation, the cabinet 3 may not be provided with the skirting board 31. Therefore, after the refrigeration appliance 1 is delivered to the user, the bottom base 2 may be directly mounted to the bottom portion of the refrigeration appliance 1 based on a state in which only the main body portion 131 is provided shown in FIG. 2, to obtain the structure shown in FIG. 1. Then, the refrigeration appliance 1 supported on the bottom base 2 is pushed into the cabinet 3 through the roller 26, to implement embedding installation. In this variation, the height of the first through hole 214 through which the second fixing member 25 passes is suitable for enabling a height from the supporting surface 211 to the mounting surface to be adapted to the height of the main body portion 131.

[0123] Alternatively, in a case that the height of the cabinet 3 is excessively limited, the bottom base 2 may be removed. In other words, the refrigeration appliance 1 is directly supported on a mounting surface, as shown in FIG. 20. In this case, the height from the bottom portion 10a of the box body 10 to the mounting surface is equal to the height of the main body portion 131.

[0124] In some embodiments, still referring to FIG. 19, an air blocking member 19 may be disposed at a position close to a rear of the bottom portion 10a of the box body 10. The air blocking member 19 extends from the bottom portion 10a of the box body 10 to the mounting surface. The air blocking member 19 is adapted to interrupt a communication path between the bottom portion 10a of the box body 10 and a rear side of the box body 10, so as to prevent air from flowing from a gap between the rear side of the box body 10 and a cabinet to an upper side of the box body 10 after the air enters an air inlet channel 14 from an air inlet 141, thereby ensuring that a circulation path from the air inlet 141, the air inlet channel 14, the compressor compartment, the air outlet channel 15 to the air outlet 151 has relatively high air flow efficiency. Further, in the y direction, the air blocking member 19 may be flush with a rear wall 102. For example, the air blocking member 19 may extend downward from a place where the bottom portion 10a of the box body 10 is connected to the rear wall 102 to the mounting surface.

[0125] In a specific implementation, still referring to FIG. 8 and FIG. 9, the supporting beam 21 may be fixed through the limiting member 27 along the rear end surface 21c in the extension direction and the rear wall 102 of the box body 10. Specifically, the rear end surface 21c is closer to the first end 21a than to the second end 21b.

[0126] Further, the limiting member 27 may be in a substantially long strip shape. Two ends of the limiting member 27 in the extension direction may be respectively fixed to the rear end surface 21c and the rear wall 102 through a fastener 28.

[0127] Therefore, the limiting member 27 is disposed to further limit the relative displacement between the bottom base 2 and the refrigeration appliance 1. Further, the limiting member 27 is disposed on a rear side of the refrigeration appliance 1. The side is usually invisible to the user in a usage state of the refrigeration appliance 1, which helps keep a beautiful and concise appearance that is visible to the user in the usage state of the refrigeration appliance 1.

[0128] In some embodiments, the rear wall 102 may include a rear cover plate 16 of a compressor compartment. The fasteners 28 may also be used as fasteners 28 between the rear cover plate 16 of the compressor compartment of the refrigeration appliance 1 and lamb leg-shaped supporting members 17. Therefore, the quantity of parts is facilitated to reduce.

[0129] For example, when the refrigeration appliance 1 is delivered, the bottom base 2 is not mounted to the bottom portion 10a of the box body 10. In this case, the rear cover plate 16 of the compressor compartment and the lamb leg-shaped supporting member 17 are fixed through the fastener 28. As the refrigeration appliance 1 is transported to the user, the fastener 28 may be removed after the bottom base 2 is mounted to the bottom portion 10a of the box body 10, and the limiting member 27 is mounted to a rear side of the box body 10 and the first end 21a of the supporting beam 21. Then, one fastener 28 is successively passed through the limiting member 27, the rear cover plate 16 of the compressor compartment, and the lamb leg-shaped supporting member 17, to complete connection and fixing thereof. Another fastener 28 is successively passed through the limiting member 27 and the rear end surface 21c, to connect and fix the box body 10 to the bottom base 2.

[0130] In a specific implementation, still referring to FIG. 3, FIG. 4, FIG. 7, and FIG. 10 to FIG. 12, the bottom base 2 may further include a pair of leveling members 29 configured to adjust a height difference between the pair of supporting beams 21 in the z direction. Specifically, a fourth through hole 291 may be formed on the bottom connection wall of the support 24. The fourth through hole 291 may be a threaded hole. The leveling member 29 may be screwed into the fourth through hole 291 from a side away from the supporting beam 21. An included angle between the supporting surface 211 and the mounting surface is adjusted by adjusting a degree to which the leveling member 29 extends out of the fourth through hole 291.

[0131] For example, a pair of leveling members 29 may be respectively mounted to the supports 24 close to the second ends 21b of a pair of supporting beams 21. After the refrigeration appliance 1 supported on the bottom base 2 is pushed into the cabinet 3, the leveling member 29 exposed outside is adjusted to adjust an included angle between each of the pair of supporting surfaces 211 and the mounting surface, to adjust a level of the refrigeration appliance 1.
