Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the priority, under 35 U.S.C. § 119, of Chinese Patent Application CN 202411392533.9, filed Sep. 30, 2024; the prior application is herewith incorporated by reference in its entirety.FIELD OF THE INVENTION

[0002] Embodiments of the present invention relate to the field of refrigeration appliance technologies, and specifically, to a refrigeration appliance.BACKGROUND OF THE INVENTION

[0003] In a multi-door refrigerator and a side-by-side refrigerator, a flipping beam is usually disposed between two doors that are configured to jointly open and close the same storage compartment, and the flipping beam is pivotally connected to one of the two doors and may pivot around the door as the door is opened and closed. A guide mechanism is further disposed in the refrigerator to guide the flipping beam to move based on a stipulated trajectory, to ensure smoothness of movement of the flipping beam.SUMMARY OF THE INVENTION

[0004] It is accordingly an object of the invention to provide an improved refrigeration appliance, which overcomes the disadvantages of the heretofore-known appliances of this general type.

[0005] With the foregoing and other objects in view there is provided, in accordance with the invention, a refrigeration appliance, including a body including an inner housing, an outer housing located on an outer side of the inner housing, and a thermal insulation space located between the inner housing and the outer housing, where the inner housing defines at least one open storage compartment; a first door including a first side and a second side that are opposite to each other, where the first side of the first door is rotatably connected to the body; a second door disposed in parallel with the first door to jointly close one storage compartment; a flipping beam pivotally connected to the second side of the first door, where the flipping beam is suitable for rotating between a first position at which the flipping beam is located when the first door is opened and a second position at which the flipping beam is located when the first door is closed, and a gap between the first door and the second door may be sealed when the flipping beam is at the second position; and a guide base, disposed on the inner housing, and cooperating with the flipping beam to guide the flipping beam to rotate in a process of opening and closing the first door.

[0006] The refrigeration appliance further includes an anti-condensation pipe including a first pipe section extending from a front side of the inner housing into the thermal insulation space, where the first pipe section extends close to the guide base.

[0007] The guide base is disposed at a top of a refrigerator and more or less needs to occupy a space that originally belongs to a thermal insulation layer, causing the thermal insulation layer at the top of the refrigerator to become thinner. However, a thinner thermal insulation layer indicates poorer thermal insulation performance. In that case, a temperature of an area at the top of the refrigerator that is directly above the guide base is prone to be lower than a dew point temperature, and consequently, condensation occurs.

[0008] In the solution in this implementation, the foregoing technical problem is resolved through an arrangement path of the anti-condensation pipe at the top of the refrigeration appliance. The anti-condensation pipe is disposed near the guide base in the thermal insulation space, so that a temperature around the guide base can be more effectively increased, to relieve and even eliminate a condensation phenomenon at the top of the refrigerator. Specifically, the first pipe section of the anti-condensation pipe is purposely routed below an area on a top surface of the outer housing in which condensation is prone to occur, and the route covers the condensation area. The anti-condensation pipe generates heat during operation of the refrigeration appliance. The heat is transmitted to the top surface of the outer housing, to increase a temperature of the top surface and enable the temperature of the top surface to be higher than the dew point temperature, thereby reliably resolving the condensation problem in the area that is at the top of the refrigeration appliance and that corresponds to the guide base. For a built-in refrigerator, an effect of relieving condensation at the top of the refrigerator by using the solution in this implementation is particularly significant. Further, in comparison to a solution to the condensation problem in which a thickness of the thermal insulation space at the top is increased by adjusting an arrangement position of another component in the refrigeration appliance, sacrificing a volume, and the like, structural complexity of this implementation is low, modification to the another component in the refrigeration appliance is small, and the volume of the storage compartment is not affected.

[0009] In addition, the first pipe section avoids a space on a front side of the inner housing, so that a groove portion does not need to be formed in an area that is on the front side of the inner housing and that corresponds to the guide base to accommodate the anti-condensation pipe, and a structure of the front side of the inner housing is simpler. In this way, it is conducive to improving a manufacturing yield during thermoforming of the inner housing, and improving product quality.

[0010] Optionally, a projection of the first pipe section along a height direction of the refrigeration appliance is disposed around the guide base. Therefore, the first pipe section is disposed around the guide base in the thermal insulation space, to ensure that heat of the anti-condensation pipe can be transmitted, with a low loss, to an area that is on the top surface of the outer housing and that directly faces the guide base, to relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance, especially in the area in which the guide base is located.

[0011] Optionally, the projection of the first pipe section along the height direction of the refrigeration appliance at least partially falls within a range of a projection of the guide base along the height direction of the refrigeration appliance. Therefore, the first pipe section is at least partially located between the guide base and the top surface of the outer housing, to mainly resolve the condensation problem in the area that is on the top surface of the outer housing and that directly faces the guide base.

[0012] Optionally, a convex hull protrudes from the inner housing into the thermal insulation space, to form a sunken mounting portion on a top wall of the inner housing, and the guide base is mounted on the mounting portion. The projection of the first pipe section along the height direction of the refrigeration appliance is disposed around the convex hull. The configuration in which the inner housing protrudes upward to form the mounting portion for mounting the guide base enables the guide base to be flush with the top wall of the inner housing. The top of the storage compartment is flat and aesthetical when viewed from the front. The thermal insulation space needs to be occupied for disposition of the convex hull, so that a thickness of the thermal insulation space between the convex hull and the top surface of the outer housing is obviously thinner than a thickness of the thermal insulation space in another area at the top of the refrigeration appliance. Therefore, in the solution in this implementation, the anti-condensation pipe is specifically disposed around the convex hull in the thermal insulation space, to reliably resolve the condensation problem in the area that is on the top surface of the outer housing and that corresponds to the guide base.

[0013] Optionally, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, and the guide base is mounted on the mounting portion. The projection of the first pipe section along the height direction of the refrigeration appliance at least partially falls within a range of a projection of the convex hull along the height direction of the refrigeration appliance. Therefore, the first pipe section at least partially passes through an area in which the thermal insulation space at the top of the refrigeration appliance is thin, specifically to resolve the condensation problem in the area that is on the top surface of the outer housing and that directly faces the guide base.

[0014] Optionally, the first pipe section is located between the convex hull and the top surface of the outer housing along the height direction of the refrigeration appliance. Therefore, the anti-condensation pipe passes above the convex hull, to ensure that the heat reliably covers an area that is on the top surface of the outer housing and that directly faces the convex hull, to better resolve the condensation problem at the top of the refrigeration appliance.

[0015] Optionally, the first pipe section extends, on a rear side of the convex hull, from one side of the convex hull to the other side of the convex hull. Therefore, the anti-condensation pipe is purposely routed below the area on the top surface of the outer housing in which condensation is prone to occur, and the route covers the condensation area, to reliably relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance.

[0016] Optionally, along the height direction of the refrigeration appliance, a first distance between the first pipe section and the top surface of the outer housing is less than a second distance between the first pipe section and the top wall of the inner housing. Therefore, the first pipe section of the anti-condensation pipe that extends into the thermal insulation space is disposed as close as possible to the top surface of the outer housing, to more effectively increase the temperature of the top surface and enable the temperature of the top surface to be higher than the dew point temperature, thereby resolving the condensation problem at the top of the refrigeration appliance.

[0017] Optionally, a ratio of the first distance to the second distance is 2:3. Therefore, the first pipe section is disposed as close as possible to the top surface of the outer housing, to ensure that the heat is radiated to the top surface with a low loss.

[0018] Optionally, a value of the first distance ranges from 10 mm to 20 mm. Optionally, a value of the second distance ranges from 20 mm to 30 mm.

[0019] Optionally, an edge of the top wall of the inner housing is folded toward the outer housing to form a first flange, an edge of the outer housing is folded to form an open groove toward the top wall, and the first flange extends into the groove, to enable the inner housing and the outer housing to be connected at the top and form an accommodating portion. The anti-condensation pipe includes a second pipe section that extends outside the thermal insulation space, the first pipe section is in communication with the second pipe section, and the second pipe section is accommodated in the accommodating portion. Therefore, the anti-condensation pipe is disposed along an entire width direction of the top of the refrigeration appliance, and most sections (for example, the second pipe section) of the anti-condensation pipe are disposed on the front side of the inner housing without damaging a structure of the inner housing. For the area in which the guide base is located, the anti-condensation pipe passes through the first flange and is laid in the thermal insulation space, to better increase a temperature near the guide base, so that a condensation phenomenon on the top surface of the outer housing and a condensation phenomenon in the front of the outer housing can be greatly improved. Further, after the door is opened, the anti-condensation pipe and the first flange are invisible to the outside, so that an appearance of the refrigeration appliance is more aesthetical.

[0020] Optionally, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, the guide base is mounted on the mounting portion, and the first pipe section is disposed at least along a side of the mounting portion away from the first flange. Therefore, the first pipe section extends deep enough into the thermal insulation space, to ensure that the generated heat is sufficient to cover an area in which the mounting portion is located, so as to relieve the condensation phenomenon at the top of the refrigeration appliance.

[0021] Optionally, the second pipe section extends along the width direction of the refrigeration appliance to be flush with two ends of the first flange. Therefore, the anti-condensation pipe is disposed in the front of the top of the refrigeration appliance along the entire width direction, to effectively resolve the condensation problem in the front of the outer housing.

[0022] Optionally, along the height direction of the refrigeration appliance, the first pipe section and the second pipe section are located at a same height. Therefore, mounting is convenient. After extending along the first flange to form the second pipe section, the anti-condensation pipe is directly folded backward to enter the thermal insulation space, and then the anti-condensation pipe is folded around the mounting portion through a shortest path and a simplest operation, to form the first pipe section.

[0023] Optionally, the first pipe section extends in a U shape. Therefore, the U-shaped first pipe section can surround at least three surfaces of the guide base, to omnidirectionally relieve the condensation phenomenon in the area that is at the top of the refrigeration appliance and that corresponds to the guide base.

[0024] Optionally, the first flange includes a groove portion. The groove portion is sunken toward the thermal insulation space, to accommodate the second pipe section, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, and the guide base is mounted on the mounting portion. A projection of the mounting portion on the first flange and the groove portion do not overlap along a depth direction of the refrigeration appliance. Therefore, the anti-condensation pipe keeps away from the first flange located on a front side of the guide base, and instead bypasses it through the thermal insulation space (namely, a section in which the first pipe section is located), so that the groove portion does not need to be provided in an area that is of the first flange and that is located on the front side of the guide base, to reduce a probability that a quality problem, such as a wrinkle, occurs in the area on the front side of the guide base during thermoforming of the inner housing, and improve a product yield.

[0025] Optionally, the first flange is provided with a first through hole through which the anti-condensation pipe extends into the thermal insulation space and a second through hole through which the anti-condensation pipe extends out of the thermal insulation space, and the first through hole and the second through hole are provided adjacent to the guide base and are respectively located on two sides of the guide base. Therefore, after extending for a distance along the front sides of the inner housing and the outer housing, the anti-condensation pipe enters the thermal insulation space through the first through hole, extends for a distance around the guide base, extends out of the thermal insulation space through the second through hole, and then continues to extend along the front sides of the inner housing and the outer housing. In this way, the anti-condensation pipe is disposed both in the front of and above the top of the refrigeration appliance to resolve the condensation problem.

[0026] Optionally, the first flange, corresponding to the guide base, includes a sealing portion that protrudes into the thermal insulation space. Therefore, disposition of the sealing portion can reduce an assembly gap between an area that is of the first flange and that corresponds to the guide base and the groove, to facilitate, during assembly, insertion of filler to block the gap to prevent leakage, and improve sealing performance of an area in front of the guide base.

[0027] Optionally, the first pipe section includes a first part that extends parallel to the first flange, where a distance between the first part and the first flange is greater than a distance between the first pipe section and the top surface of the outer housing. Therefore, the first pipe section is disposed as close as possible to the top surface of the outer housing, and extends as far as possible into the thermal insulation space along the depth direction of the refrigeration appliance, to enable a heat radiating area of the first pipe section to cover more areas at the top of the refrigeration appliance, especially, an area corresponding to the guide base.

[0028] Optionally, the distance between the first part and the first flange is greater than a distance between the first pipe section and the top wall of the inner housing. Therefore, the first pipe section extends as far as possible into the thermal insulation space along the depth direction of the refrigeration appliance, to enable the heat radiating area of the first pipe section to cover more areas at the top of the refrigeration appliance, especially, the area corresponding to the guide base.

[0029] Optionally, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, the guide base is mounted on the mounting portion, the mounting portion includes a first area and a second area that are disposed in parallel along the width direction of the refrigeration appliance, and the first pipe section includes a first portion disposed around the first area and a second portion disposed around the second area. Along the height direction of the refrigeration appliance, there is a non-zero height difference between the first area and the second area and there is a non-zero height difference between the first portion and the second portion, and the height difference between the first portion and the second portion matches the height difference between the first area and the second area. Therefore, the first pipe section is disposed attaching to an outer contour of the mounting portion, to further optimize an anti-condensation effect in an area that is at the top of the refrigeration appliance and that corresponds to the mounting portion.

[0030] Optionally, the guide base basically does not protrude from the top wall of the inner housing in the storage compartment. Therefore, there is no additional concave-convex structure at the top of the storage compartment (namely, the top wall of the inner housing), and after the door is opened, an appearance of the front of the storage compartment is more aesthetical.

[0031] Optionally, the refrigeration appliance further includes a first fixing member and a second fixing member. The first fixing member is fixed on the top wall of the inner housing and extends into the thermal insulation space, and the second fixing member passes through the guide base and is fixed on the first fixing member. In this way, the guide base is reliably mounted in the refrigeration appliance by using the first fixing member and the second fixing member, and in cooperation with the first pipe section, a part of the first fixing member that is located in the thermal insulation space is prevented from affecting the anti-condensation effect at the top of the refrigeration appliance.

[0032] Optionally, the flipping beam includes a first guide member, one of the guide base and the first guide member includes a guide groove, and the other of the guide base and the first guide member includes a protruding member suitable for moving in the guide groove. Therefore, through cooperation between the guide groove and the protruding member, the flipping beam is guided to rotate based on a preset trajectory as the door is opened and closed.

[0033] Optionally, the projection of the first pipe section along the height direction of the refrigeration appliance bypasses the flipping beam, and extends, on a rear side of the flipping beam, from one side of the flipping beam to the other side of the flipping beam. Therefore, the condensation problem in an area that is on the top surface of the outer housing and that directly faces the flipping beam is specifically resolved.

[0034] Other features which are considered as characteristic for the invention are set forth in the appended claims.

[0035] 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.

[0050] A guide mechanism needs to be fixed at a top of a refrigerator by using a fixing member. The fixing member passes through a top wall of a liner of the refrigerator and extends into a thermal insulation layer. This may affect thermal insulation performance of the thermal insulation layer. In addition, in some refrigerators, to improve aesthetics of a storage compartment, the top wall of the liner protrudes upward to form a mounting portion. The guide mechanism is mounted on the mounting portion, so that the top wall of the storage compartment is flat when viewed from the front. However, that causes a thinner thermal insulation layer and poorer thermal insulation performance. Practices show that for either of the foregoing two situations, heat generated by a conventional anti-condensation pipe disposed on a front side of the top cannot increase a temperature of an area at the top of the refrigerator above a dew point temperature, causing a condensation phenomenon still to occur at the top of the refrigerator. The condensation problem is especially prominent in a built-in refrigerator. Because a gap between a top of the built-in refrigerator and a cabinet is very small, condensation is more likely to occur.

[0051] In addition, in a conventional refrigerator, a groove portion needs to be provided on a flange of the liner to accommodate the anti-condensation pipe. However, most liners are formed by thermoforming. Regardless of disposition of the foregoing fixing member or the mounting portion that protrudes upward, if the groove portion further needs to be formed at the flange in front of the fixing member or the mounting portion, a quality problem such as a wrinkle is prone to occur during thermoforming, resulting in a lower manufacturing yield of the liner.

[0052] In order to resolve the foregoing technical problem, an embodiment of the present invention provides a refrigeration appliance, including: a body, including an inner housing, an outer housing located on an outer side of the inner housing, and a thermal insulation space located between the inner housing and the outer housing, where the inner housing defines at least one open storage compartment; a first door, including a first side and a second side that are opposite to each other, where the first side of the first door is rotatably connected to the body; a second door, disposed in parallel with the first door to jointly close one storage compartment; a flipping beam, pivotally connected to the second side of the first door, where the flipping beam is suitable for rotating between a first position at which the flipping beam is located when the first door is opened and a second position at which the flipping beam is located when the first door is closed, and a gap between the first door and the second door may be sealed when the flipping beam is at the second position; and a guide base, disposed on the inner housing, and cooperating with the flipping beam to guide the flipping beam to rotate in a process of opening and closing the first door. The refrigeration appliance further includes: an anti-condensation pipe, including a first pipe section extending from a front side of the inner housing into the thermal insulation space, where the first pipe section extends close to the guide base.

[0053] In the solution in this implementation, the foregoing problem is resolved by optimizing an arrangement path of the anti-condensation pipe at a top of the refrigeration appliance. The anti-condensation pipe is disposed near the guide base in the thermal insulation space, so that a temperature around the guide base can be more effectively increased, to relieve and even eliminate a condensation phenomenon at the top of the refrigerator. Specifically, the first pipe section of the anti-condensation pipe is purposely routed below an area on a top surface of the outer housing in which condensation is prone to occur, and the route covers the condensation area. The anti-condensation pipe generates heat during operation of the refrigeration appliance. The heat is transmitted to the top surface of the outer housing, to increase a temperature of the top surface and enable the temperature of the top surface to be higher than a dew point temperature, thereby reliably resolving the condensation problem in an area that is at the top of the refrigeration appliance and that corresponds to the guide base. For a built-in refrigerator, an effect of relieving condensation at the top of the refrigerator by using the solution in this implementation is particularly significant. Further, in comparison to a solution to the condensation problem in which a thickness of the thermal insulation space at the top is increased by adjusting an arrangement position of another component in the refrigeration appliance, sacrificing a volume, and the like, structural complexity of the solution in this implementation is low, modification to the another component in the refrigeration appliance is small, and the volume of the storage compartment is not affected.

[0054] In addition, the first pipe section avoids a space on a front side of the inner housing, so that a groove portion does not need to be formed in an area that is on the front side of the inner housing and that corresponds to the guide base to accommodate the anti-condensation pipe, and a structure of the front side of the inner housing is simpler. In this way, it is conducive to improving a manufacturing yield during thermoforming of the inner housing, and improving product quality.

[0055] In order to make the foregoing objectives, features, and advantages of the present invention more comprehensible, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0056] Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen a diagrammatic illustration of a refrigeration appliance 1 according to an embodiment of the present invention. FIG. 2 to FIG. 5 exemplarily show an internal structure of a top of the refrigeration appliance 1 from different perspectives. In order to show the internal structure of the refrigeration appliance 1 more clearly, a top surface 102a of an outer housing 102 is omitted in FIG. 3 and FIG. 5, and a first door 11 and a second door 12 are omitted in FIG. 4.

[0057] The refrigeration appliance 1 may be a refrigerator, a refrigerated cabinet, a wine cooler, and the like. FIG. 1 is exemplarily shown by using a multi-door refrigerator as an example. During actual application, a configuration of a guide base and an anti-condensation pipe 2 for the top of the refrigeration appliance 1 in this implementation may also be applicable to various forms of refrigerators having a left door and a right door, such as a cross door refrigerator, a French door refrigerator, and a side-by-side refrigerator.

[0058] For ease of description, in the solution in this implementation, a width direction of the refrigeration appliance 1 is denoted as a direction x, a depth direction of the refrigeration appliance 1 is denoted as a direction y, and a height direction of the refrigeration appliance 1 is denoted as a direction z. In the solution in this implementation, a front direction and a rear direction respectively refer to the direction y and an opposite direction of the direction y. A front or a front side refers to a direction along which the refrigeration appliance 1 faces a user when the refrigeration appliance 1 is in use, and a rear or a rear side refers to a direction along which the refrigeration appliance 1 faces away from the user when the refrigeration appliance 1 is in use. In the solution in this implementation, an up direction and a down direction respectively refer to the direction z and an opposite direction of the direction z. A top refers to a direction that is more up along a gravity direction when the refrigeration appliance 1 is in use, and a bottom refers to a direction that is in contact with or closest to the ground when the refrigeration appliance is in use.

[0059] Specifically, referring to FIG. 1 to FIG. 6, the refrigeration appliance 1 may include a body 10, including an inner housing 101, an outer housing 102 located on an outer side of the inner housing 101, and a thermal insulation space 103 located between the inner housing 101 and the outer housing 102. For example, the inner housing 101 may include a top wall 101a and a bottom wall (not shown in the figure) that are opposite to each other along the direction z, and a pair of side walls 101b that are opposite to each other along the direction x and a rear wall (not shown in the figure). The top wall 101a, the bottom wall, the pair of side walls 101b, and the rear wall jointly enclose an open storage space that faces forward. Further, the outer housing 102 may include the top surface 102a and a bottom surface (not shown in the figure) that are opposite to each other along the direction z, and a pair of side surfaces 102b that are opposite to each other along the direction x and a rear surface 102c. The top surface 102a, the bottom surface, the side surfaces 102b, and the rear surface 102c jointly enclose an open accommodating space that faces forward, and the inner housing 101 is accommodated in the accommodating space. Further, the thermal insulation space 103 filled with a thermal insulation material may be included between the outer housing 102 and the inner housing 101. A thermal insulation layer formed by the thermal insulation space has an effect of isolating heat, to ensure a good refrigerating / freezing effect of the storage space.

[0060] Further, the inner housing 101 defines at least one open storage compartment 104. For example, the foregoing storage space may be divided into at least one storage compartment 104 along the direction z and / or the direction x. Using a refrigerator as an example, the storage compartment 104 may be, for example, a freezing compartment, a refrigerating compartment, or a temperature-variable compartment. Each storage compartment 104 may be configured with at least one door to open or close the storage compartment 104. The door may be a hinge door or a drawer-type door. FIG. 1 and FIG. 6 are exemplarily shown by using an example in which two doors are configured to jointly open or close one storage compartment 104.

[0061] Further, the refrigeration appliance 1 may include the first door 11, including a first side 11a and a second side 11b that are opposite to each other along the direction x, and the first side 11a of the first door 11 is rotatably connected to the body 10. Further, the refrigeration appliance 1 may further include the second door 12 that is disposed in parallel with the first door 11 to jointly close one storage compartment 104. For either of the first door 11 and the second door 12, the door may include a thermal insulation layer 112 filled with a thermal insulation material. When the first door 11 and the second door 12 are configured to close the storage compartment 104, the thermal insulation layer 112 has an effect of isolating heat, to ensure a good refrigerating / freezing effect of the storage compartment 104. For either of the first door 11 and the second door 12, the door may include a front panel 110, a rear panel 113 that faces the body 10 when the door is closed, and a frame 114 disposed along a periphery of the door. The thermal insulation layer 112 is located between the front panel 110 and the rear panel 113. In some embodiments, the front panel 110 forms at least a part of a front boundary of the thermal insulation layer 112, so that the thermal insulation material is in contact with a rear side of the front panel 110. In some other embodiments, another door panel may be further disposed on the rear side of the front panel 110. The front panel 110 may be a metal door housing, a glass plate, or a ceramic plate. In some embodiments, the first door 11 and the second door 12 may be respectively movably connected to the body 10 through a hinge 13. For example, the first side 11a of the first door 11 is connected to the body 10 through the hinge 13 on two sides along the direction z.

[0062] A door handle 122 may be disposed on one of adjacent sides of the first door 11 and the second door 12. For example, referring to FIG. 2, the door handle 122 may be disposed on a side that is of the second door 12 and that is close to the second side 11b of the first door 11. The user may open the second door 12 by holding the door handle 122, and then open the first door 11.

[0063] A shelf 121 may be disposed on the rear panel 113 of either of the first door 11 and the second door 12, for the user to store objects. The shelf 121 may be, for example, a bottle shelf or an egg shelf.

[0064] When both the first door 11 and the second door 12 are closed, there is a gap between the second side 11b of the first door 11 and the second door 12. In order to seal the gap, the refrigeration appliance 1 may further include a flipping beam 14 that is pivotally connected to the second side 11b of the first door 11. The flipping beam 14 is suitable for rotating between a first position at which the flipping beam 14 is located when the first door 11 is opened and a second position at which the flipping beam 14 is located when the first door 11 is closed, and the gap between the first door 11 and the second door 12 may be sealed when the flipping beam 14 is at the second position.

[0065] For example, when the first door 11 is in an open state shown in FIG. 6, the flipping beam 14, which has a cross section that is in a shape of a rectangle, may be at the first position, that is, the flipping beam 14 is returned to a position at which a narrow side faces the body 10. In this case, the flipping beam 14 does not extend out of the second side 11b of the first door 11 along a side direction, so that when the second door 12 is in a closed state, if the first door 11 is closed, the flipping beam 14 can pass over the second door 12. Further, when the first door 11 is closed, the flipping beam 14 enters the inside of the body 10 and rotates around a vertical axis in this process, so that after entering the body 10, a butting surface 14a formed on a wide side of the flipping beam 14 is flush with a front side (for example, a first flange 18) of the inner housing 101 (as shown in FIG. 3). In this case, the flipping beam 14 is at the second position. The first door 11 and the second door 12 are each provided with a door seal member 111 around the rear panel 113. When the first door 11 and the second door 12 are configured to close the storage compartment 104, the door seal member 111 abuts against the first flange 18. At the second position, the first flange 18 and the butting surface 14a form a support surface that can cover the gap between the first door 11 and the second door 12, and the door seal members 111 of the first door 11 and the second door 12 abut against the support surface in a sealing manner, as shown in FIG. 2. Further, the refrigeration appliance 1 may further include a guide base 141, which is disposed on the inner housing 101, and cooperates with the flipping beam 14 to guide the flipping beam 14 to rotate in a process of opening and closing the first door 11. The guide base 141 may be disposed at the top of the refrigeration appliance 1 and disposed close to an opening of the storage compartment 104. In some embodiments, referring to FIG. 3, FIG. 6, FIG. 7, and FIG. 9, the flipping beam 14 may include a first guide member 19, one of the guide base 141 and the first guide member 19 may include a guide groove 191, and the other of the guide base 141 and the first guide member 19 includes a protruding member 192 suitable for moving in the guide groove 191. The protruding member 192 may have a cross section in an arc shape, and may move in the guide groove 191 to drive the flipping beam 14 to rotate. The guide groove 191 is in a curved shape, and has an entry 191a facing the protruding member 192.

[0066] When the first door 11 is closed, an end that is close to the narrow side and that is of the protruding member 192 on the flipping beam 14 at the first position enters the entry 191a of the guide groove 191, and an edge of a convex side of the protruding member 192 starts to come into contact with a groove wall of the guide groove 191. As the first door 11 is further closed, the edge of the convex side of the protruding member 192 slides along the guide groove 191, to drive the flipping beam 14 to pivot around the vertical axis until the flipping beam 14 is at the second position. In this case, the butting surface 14a is flush with the first flange 18. Similarly, when the first door 11 is opened, the protruding member 192 also rotates in the guide groove 191 to drive the flipping beam 14 to rotate to the first position, so that the flipping beam 14 can pass through the closed second door 12, and the first door 11 can be opened when the second door 12 is closed. Therefore, through cooperation between the guide groove 191 and the protruding member 192, the flipping beam 14 is guided to rotate based on a preset trajectory as the door (for example, the first door 11) is opened and closed.

[0067] Further, the refrigeration appliance 1 may further include the anti-condensation pipe 2, including a first pipe section 21 that extends from the front side of the inner housing 101 into the thermal insulation space 103, and the first pipe section 21 extends close to the guide base 141. For example, referring to FIG. 1, the anti-condensation pipe 2 may be continuously disposed from a compressor compartment (not shown in the figure) disposed at the bottom of the body 10 to the top of the refrigeration appliance 1 along the thermal insulation space 103 between the pair of side walls 101b and the pair of side surfaces 102b. The anti-condensation pipe 2 may be connected to a condenser (not shown in the figure) of the refrigeration appliance 1, and the anti-condensation pipe 2 may include a refrigerant at a specific temperature. Further, the anti-condensation pipe 2 may extend and be disposed around the opening of each storage compartment 104.

[0068] Referring to FIG. 1, FIG. 6, and FIG. 7, at the top of the refrigeration appliance 1, the anti-condensation pipe 2 extends from one end of the inner housing 101 along the direction x against the front side of the inner housing 101 to a position near the guide base 141 along the direction x, passes through the inner housing 101 and enters the thermal insulation space 103, extends around the guide base 141 for a distance (namely, the first pipe section 21) in the thermal insulation space 103, extends out of the inner housing 101, and continues to extend along the front side of the inner housing 101 to the other end of the inner housing 101 along the direction x.

[0069] Based on the above, in the solution in this implementation, an arrangement path of the anti-condensation pipe 2 at the top of the refrigeration appliance 1 is optimized. The anti-condensation pipe 2 is disposed near the guide base 141 in the thermal insulation space 103, so that a temperature around the guide base 141 can be more effectively increased, to relieve and even eliminate a condensation phenomenon at the top of the refrigerator. Specifically, the first pipe section 21 of the anti-condensation pipe 2 is purposely routed below an area on the top surface 102a of the outer housing 102 in which condensation is prone to occur, and the route covers the condensation area. The anti-condensation pipe 2 generates heat during operation of the refrigeration appliance 1. The heat is transmitted to the top surface 102a of the outer housing 102, to increase a temperature of the top surface 102a and enable the temperature of the top surface 102a to be higher than a dew point temperature, so as to reliably resolve the condensation problem in an area that is at the top of the refrigeration appliance 1 and that corresponds to the guide base 141. For a built-in refrigerator, an effect of relieving condensation at the top of the refrigerator by using the solution in this implementation is particularly significant. Further, structural complexity of the solution in this implementation is low, modification to another component in the refrigeration appliance 1 is small, and a volume of the storage compartment 104 is not affected.

[0070] In addition, the first pipe section 21 avoids a space on the front side of the inner housing 101, so that a groove portion 17 does not need to be formed in an area that is on the front side of the inner housing 101 and that corresponds to the guide base 141 to accommodate the anti-condensation pipe 2, and a structure of the front side of the inner housing 101 is simpler. In this way, it is conducive to improving a manufacturing yield during thermoforming of the inner housing 101, and improving product quality.

[0071] In a specific implementation, referring to FIG. 2 to FIG. 9, a projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 may be disposed around the guide base 141. Specifically, an outer contour of a projection of the guide base 141 along the direction z is approximately in a shape of a rectangle, and the first pipe section 21 is located at least near three sides of the rectangle. For example, the first pipe section 21 may be disposed close to a pair of opposite side wall surfaces of the guide base 141 along the direction x, and disposed close to a rear side wall surface of the guide base 141 along the direction y. Therefore, the first pipe section 21 is disposed around the guide base 141 in the thermal insulation space 103, to ensure that heat of the anti-condensation pipe 2 can be transmitted, with a low loss, to an area that is on the top surface 102a of the outer housing 102 and that directly faces the guide base 141, to relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance 1, especially in the area in which the guide base 141 is located.

[0072] Further, the projection of the first pipe section 21 along the direction z may be located outside the guide base 141, that is, the first pipe section 21 is disposed around the guide base 141 from a periphery. Therefore, the heat generated by the first pipe section 21 can be radiated to an area in the thermal insulation space 103 as much as possible along the depth direction of the refrigeration appliance 1, to optimize an anti-condensation effect at the top of the refrigeration appliance 1.

[0073] In a variable example, the projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 may at least partially fall within a range of a projection of the guide base 141 along the height direction (for example, the direction z) of the refrigeration appliance 1. In other words, the first pipe section 21 may at least partially pass above the guide base 141. Therefore, the first pipe section 21 is at least partially located between the guide base 141 and the top surface 102a of the outer housing 102, to mainly resolve the condensation problem in the area that is on the top surface 102a of the outer housing 102 and that directly faces the guide base 141.

[0074] In some embodiments, a relative position relationship between the projection of the first pipe section 21 along the direction z and the projection of the guide base 141 along the direction z may be determined based on a size of an area in which condensation is prone to occur at the top of the refrigeration appliance 1. For example, the size of the condensation area at the top of the refrigeration appliance 1 may be determined through an experiment. A larger condensation area indicates a smaller overlapping degree between the projection of the first pipe section 21 along the direction z and the projection of the guide base 141 along the direction z, and a larger degree to which the first pipe section 21 extends into the thermal insulation space 103 along an opposite direction of the direction y.

[0075] In some embodiments, a value of a distance between the first pipe section 41 and the front side (for example, the first flange 18) of the inner housing 101 along the direction y may range from 30 mm to 45 mm. For example, the distance between the first pipe section 41 and the first flange 18 along the direction y may be 38 mm.

[0076] In a variable example, the projection of the first pipe section 21 along the direction z may zigzag extend in an area surrounded by the projection of the guide base 141 along the direction z. Therefore, the condensation problem in the area that is at the top of the refrigeration appliance 1 and that corresponds to the guide base 141 can be further improved.

[0077] In a specific implementation, referring to FIG. 2 to FIG. 5 and FIG. 7 to FIG. 10, a convex hull 15 may protrude from the inner housing 101 into the thermal insulation space 103, to form a sunken mounting portion 142 on the top wall 101a of the inner housing 101. Specifically, the guide base 141 is mounted on the mounting portion 142.

[0078] Further, the guide base 141 basically does not protrude from the top wall 101a of the inner housing 101 in the storage compartment 104.

[0079] Therefore, there is no additional concave-convex structure at the top (namely, the top wall 101a of the inner housing 101) of the storage compartment 104, and after the door (for example, the first door 11 and the second door 12) is opened, an appearance of the front of the storage compartment 104 is aesthetical.

[0080] Further, the projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 may be disposed around the convex hull 15. For example, the projection of the first pipe section 21 along the direction z at least passes through three sides of the convex hull 15 whose outer contour is approximately in a shape of a rectangle. Alternatively, the projection of the first pipe section 21 along the direction z may at least partially fall within a range of a projection of the convex hull 15 along the direction z. The first pipe section 21 at least partially passes through an area in which the thermal insulation space 103 at the top of the refrigeration appliance 1 is thin, so that the condensation problem in the area that is on the top surface 102a of the outer housing 102 and that directly faces the guide base 141 is specifically resolved.

[0081] Therefore, the configuration in which the inner housing 101 protrudes upward to form the mounting portion 142 for mounting the guide base 141 enables the guide base 141 to be flush with the top wall 101a of the inner housing 101. The top of the storage compartment 104 is flat and aesthetical when viewed from the front. The thermal insulation space 103 needs to be occupied for disposition of the convex hull 15, so that a thickness of the thermal insulation space 103 between the convex hull 15 and the top surface 102a of the outer housing 102 is obviously thinner than a thickness of the thermal insulation space 103 in another area at the top of the refrigeration appliance 1. Therefore, in the solution in this implementation, the anti-condensation pipe 2 is specifically disposed around the convex hull 15 in the thermal insulation space 103, to reliably resolve the condensation problem in the area that is on the top surface 102a of the outer housing 102 and that corresponds to the guide base 141.

[0082] In some embodiments, the refrigeration appliance 1 may further include a first fixing member 145 and a second fixing member 146. The first fixing member 145 is fixed on the top wall 101a of the inner housing 101 and extends into the thermal insulation space 103, and the second fixing member 146 passes through the guide base 141 and is fixed on the first fixing member 145. Specifically, the convex hull 15 may be provided with a third through hole 147 for the first fixing member 145 to pass through, and the first fixing member 145 is screwed from the thermal insulation space 103 into the third through hole 147 and is at least partially screwed out from a side on which the mounting portion 142 is located. The guide base 141 is placed in the mounting portion 142, a mounting hole 193 provided on the guide base 141 is aligned with the third through hole 147, and the second fixing member 146 extends through the mounting hole 193 and is fixed on the first fixing member 145. The second fixing member 146 may be, for example, a screw. In this way, the guide base 141 is reliably mounted in the refrigeration appliance 1 by using the first fixing member 145 and the second fixing member 146, and in cooperation with the first pipe section 21, a part of the first fixing member 145 that is located in the thermal insulation space 103 is prevented from affecting the anti-condensation effect at the top of the refrigeration appliance 1.

[0083] In a specific implementation, the first pipe section 21 may be located between the convex hull 15 and the top surface 102a of the outer housing 102 along the height direction (for example, the direction z) of the refrigeration appliance 1. Therefore, the anti-condensation pipe 2 passes above the convex hull 15, to ensure that the heat reliably covers an area that is on the top surface 102a of the outer housing 102 and that directly faces the convex hull 15, to better resolve the condensation problem at the top of the refrigeration appliance 1.

[0084] In a specific implementation, referring to FIG. 2 to FIG. 9, the first pipe section 21 may extend, on a rear side of the convex hull 15, from one side of the convex hull 15 to the other side of the convex hull 15. Specifically, using a viewing angle in FIG. 8 as an example, the first pipe section 21 extends approximately in a U shape. After extending, along the opposite direction of the direction y, from a lower left corner of the convex hull 15 along the direction x and passing through a left side surface of the convex hull 15, the first pipe section 21 extends, along an opposite direction of the direction x, from a rear side of the convex hull 15, and passes through a rear side surface of the convex hull 15, and then extends through a right side surface of the convex hull 15 along the direction y.

[0085] Therefore, the anti-condensation pipe 2 is purposely routed below the area on the top surface 102a of the outer housing 102 in which condensation is prone to occur, and the route covers the condensation area, to reliably relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance 1. Further, the U-shaped first pipe section 21 can surround at least three surfaces of the guide base 141, to omnidirectionally relieve the condensation phenomenon in the area that is at the top of the refrigeration appliance 1 and that corresponds to the guide base 141.

[0086] In a specific implementation, referring to FIG. 4, along the height direction (for example, the direction z) of the refrigeration appliance 1, a first distance L1 between the first pipe section 21 and the top surface 102a of the outer housing 102 may be less than a second distance L2 between the first pipe section 21 and the top wall 101a of the inner housing 101. In other words, in comparison to the top wall 101a of the inner housing 101, the first pipe section 21 is disposed closer to the top surface 102a of the outer housing 102.

[0087] Therefore, the first pipe section 21 of the anti-condensation pipe 2 that extends into the thermal insulation space 103 is disposed as close as possible to the top surface 102a of the outer housing 102, to more effectively increase the temperature of the top surface 102a and enable the temperature of the top surface 102a to be higher than the dew point temperature, so as to resolve the condensation problem at the top of the refrigeration appliance 1.

[0088] In some embodiments, a ratio of the first distance L1 to the second distance L2 may be 2:3. A value of the first distance L1 may range from 10 mm to 20 mm. A value of the second distance L2 may range from 20 mm to 30 mm. For example, the first distance L1 may be 16 mm, and the second distance L2 may be 24 mm. Therefore, the first pipe section 21 is disposed as close as possible to the top surface 102a of the outer housing 102, to ensure that the heat is radiated to the top surface 102a with a low loss.

[0089] In a specific implementation, referring to FIG. 2 to FIG. 12, an edge of the top wall 101a of the inner housing 101 may be folded toward the outer housing 102 to form the first flange 18, and an edge of the outer housing 102 is folded to form an open groove 105 toward the top wall 101a. Specifically, walls that form the groove 105 may include a second wall 105b and a third wall 105c that are opposite to each other along the direction y, and a first wall 105a located between the second wall 105b and the third wall 105c. The third wall 105c is located in front of the second wall 105b along the direction y.

[0090] Further, the first flange 18 may include a groove portion 17, and the groove portion 17 is sunken toward the thermal insulation space 103.

[0091] Further, the first flange 18 extends into the groove 105, to enable the inner housing 101 and the outer housing 102 to be connected at the top and form an accommodating portion 16. After the first flange 18 is inserted into the groove 105, the groove portion 17 is attached to the second wall 105b. In addition, along the direction z, the third wall 105c abuts against an end wall formed by backward folding of the first flange 18, so that the outer housing 102 and the inner housing 101 is basically flush on a front side of the body 10.

[0092] Further, the anti-condensation pipe 2 may include a second pipe section 22 that extends outside the thermal insulation space 103, the first pipe section 21 is in communication with the second pipe section 22, and the second pipe section 22 is accommodated in the accommodating portion 16. For example, the groove portion 17 and the third wall 105c jointly enclose the accommodating portion 16 extending approximately along the direction x, to accommodate the second pipe section 22. During assembly, the second pipe section 22 may be first placed in the groove portion 17, and an opening of the groove portion 17 is adhered by using an aluminum foil tape to fix the second pipe section 22. Then, the first flange 18 is inserted into the groove 105, and the groove portion 17 and the third wall 105c cooperate to confine the second pipe section 22 in the accommodating portion 16.

[0093] Therefore, the anti-condensation pipe 2 is disposed along the entire width direction of the top of the refrigeration appliance 1, and most sections (for example, the second pipe section 22) of the anti-condensation pipe 2 are disposed on the front side of the inner housing 101 without damaging a structure of the inner housing. For the area in which the guide base 141 is located, the anti-condensation pipe 2 passes through the first flange 18 and is laid in the thermal insulation space 103, to better increase a temperature near the guide base 141, so that a condensation phenomenon on the top surface 102a of the outer housing 102 and a condensation phenomenon in the front of the outer housing 102 can be greatly improved. Further, after the door is opened, the anti-condensation pipe 2 and the first flange 18 are invisible to the outside, so that an appearance of the refrigeration appliance 1 is more aesthetical.

[0094] In a specific implementation, still referring to FIG. 2 to FIG. 9, the first pipe section 21 is disposed at least along a side of the mounting portion 142 away from the first flange 18. In other words, along the direction y, the mounting portion 142 is located between the first pipe section 21 and the first flange 18. Therefore, the first pipe section 21 extends deep enough into the thermal insulation space 103, to ensure that the generated heat is sufficient to cover an area in which the mounting portion 142 is located, so as to relieve the condensation phenomenon at the top of the refrigeration appliance 1. Further, the anti-condensation pipe 2 bypasses the first flange 18 in front of the mounting portion 142, so that the groove portion 17 does not need to be provided on the first flange 18 in the area, which is conducive to improving a yield rate during thermoforming of the inner housing 101.

[0095] In some embodiments, while extending generally along the direction x, the groove portion 17 is further slightly displaced up and down along the direction z, as shown in FIG. 3. Therefore, a labyrinth groove may be formed, which is convenient for subsequently sealing a gap (as shown in FIG. 12) between the groove portion 17 and the second wall 105b by using foam and an adhesive tape, and is conductive to better preventing foam leakage.

[0096] In a specific implementation, referring to FIG. 6 and FIG. 7, the second pipe section 22 extends along the width direction (for example, the direction x) of the refrigeration appliance 1 to be flush with two ends of the first flange 18. Therefore, the anti-condensation pipe 2 is disposed in the front of the top of the refrigeration appliance 1 along the entire width direction, to effectively resolve the condensation problem in the front of the outer housing 102.

[0097] In a specific implementation, referring to FIG. 5 and FIG. 7, along the height direction (for example, the direction z) of the refrigeration appliance 1, the first pipe section 21 and the second pipe section 22 may be located at a same height. In other words, when the anti-condensation pipe 2 is disposed at the top of the refrigeration appliance 1, in addition to extending along the direction x, the anti-condensation pipe 2 is folded only along the direction y and the opposite direction of the direction y to be disposed in the thermal insulation space 103, and there is no obvious folding and deformation along the direction z. Therefore, mounting is convenient. After extending along the first flange 18 to form the second pipe section 22, the anti-condensation pipe 2 is directly folded backward to enter the thermal insulation space 103, and then the anti-condensation pipe 2 is folded around the mounting portion 142 through a shortest path and a simplest operation, to form the first pipe section 21.

[0098] In a specific implementation, referring to FIG. 7 to FIG. 9, a projection of the mounting portion 142 on the first flange 18 and the groove portion 17 do not overlap along the depth direction (for example, the direction y) of the refrigeration appliance 1. Therefore, the anti-condensation pipe 2 keeps away from the first flange 18 located on a front side of the guide base 141, and instead bypasses it through the thermal insulation space 103 (namely, a section in which the first pipe section 21 is located), so that the groove portion 17 does not need to be provided in an area that is of the first flange 18 and that is located on the front side of the guide base 141, to reduce a probability that a quality problem, such as a wrinkle, occurs in the area on the front side of the guide base 141 during thermoforming of the inner housing 101, and improve a product yield.

[0099] In a specific implementation, referring to FIG. 2 to FIG. 12, the first flange 18 may be provided with a first through hole 181 through which the anti-condensation pipe 2 extends into the thermal insulation space 103 and a second through hole 182 through which the anti-condensation pipe extends out of the thermal insulation space 103. The first through hole 181 and the second through hole 182 are provided adjacent to the guide base 141 and are respectively located on two sides of the guide base 141 along the direction x. Further, the second wall 105b may be provided with a fourth through hole 106 corresponding to the first through hole 181 and a fifth through hole 107 corresponding to the second through hole 182.

[0100] Therefore, after extending for a distance along the front sides (namely, the groove portions 17) of the inner housing 101 and the outer housing 102, the anti-condensation pipe 2 enters the thermal insulation space 103 through the first through hole 181 (and the fourth through hole 106), extends for a distance around the guide base 141, extends out of the thermal insulation space 103 through the second through hole 182 (and the fifth through hole 107), and then continues to extend along the front sides (namely, the groove portions 17) of the inner housing 101 and the outer housing 102. In this way, the anti-condensation pipe 2 is disposed both in the front of and above the top of the refrigeration appliance 1 to resolve the condensation problem.

[0101] In some embodiments, the first through hole 181 and the second through hole 182 are preferably provided in an area in which the groove portion 17 is located, that is, the groove portion 17 is interrupted by the first through hole 181 and the second through hole 182. Therefore, referring to FIG. 12, structures of open holes on the inner housing 101 and the outer housing 102 for the anti-condensation pipe 2 to extend into and extend out of the thermal insulation space 103 are more complex, and during assembly, the open holes can be blocked only by inserting a small amount of filler, to avoid foam leakage.

[0102] In a specific implementation, referring to FIG. 2 to FIG. 4 and FIG. 7 to FIG. 10, the first flange 18 may include, corresponding to the guide base 141, a sealing portion 183 that protrudes toward the thermal insulation space 103.

[0103] Specifically, an extent to which the sealing portion 183 is sunken from the first flange 18 toward the thermal insulation space 103 may be less than an extent to which the groove portion 17 is sunken from the first flange 18 toward the thermal insulation space 103. Correspondingly, after the first flange 18 is inserted into the groove 105, a small and non-zero assembly gap may still exist between the sealing portion 183 and the second wall 105b. However, the assembly gap is at least smaller than an assembly gap between an area that is of the first flange 18 and that is not sunken toward the thermal insulation space 103 and the second wall 105b. Therefore, disposition of the sealing portion 183 can reduce an assembly gap between an area that is of the first flange 18 and that corresponds to the guide base 141 and the groove 105, to facilitate, during assembly, insertion of filler (for example, foam) to block the gap to prevent leakage, and improve sealing performance of an area in front of the guide base 141.

[0104] In a specific implementation, referring to FIG. 5 and FIG. 7 to FIG. 9, the first pipe section 21 may include a first part that extends parallel to the first flange 18. Further, the first pipe section 21 may further include a second part that extends perpendicular to the first flange 18, and the second part is located at two ends of the first part that are opposite to each other along the direction x, to form, together with the first part, the first pipe section 21 that extends in a U shape.

[0105] In some embodiments, a distance between the first part and the first flange 18 may be greater than the distance (namely, the first distance L1) between the first pipe section 21 and the top surface 102a of the outer housing 102. Therefore, the first pipe section 21 is disposed as close as possible to the top surface 102a of the outer housing 102, and extends as far as possible into the thermal insulation space 103 along the depth direction (for example, the direction y) of the refrigeration appliance 1, to enable a heat radiating area of the first pipe section 21 to cover more areas at the top of the refrigeration appliance 1, especially, an area corresponding to the guide base 141.

[0106] In some embodiments, the distance between the first part and the first flange 18 may be greater than the distance (namely, the second distance L2) between the first pipe section 21 and the top wall 101a of the inner housing 101. Therefore, the first pipe section 21 extends as far as possible into the thermal insulation space 103 along the depth direction (for example, the direction y) of the refrigeration appliance 1, to enable the heat radiating area of the first pipe section 21 to cover more areas of the top of the refrigeration appliance 1, especially, the area corresponding to the guide base 141.

[0107] In a specific implementation, referring to FIG. 5, FIG. 7, FIG. 8, and FIG. 10, the mounting portion 142 may include a first area 143 and a second area 144 that are disposed in parallel along the width direction (for example, the direction x) of the refrigeration appliance 1. Further, along the height direction (for example, the direction z) of the refrigeration appliance 1, there is a non-zero height difference between the first area 143 and the second area 144. For example, the first area 143 protrudes further into the thermal insulation space 103 than the second area 144 does.

[0108] Further, the first pipe section 21 may include a first portion 211 disposed around the first area 143 and a second portion 212 disposed around the second area 144. The first portion 211 and the second portion 212 may be flush along the direction z. In other words, a part (namely, the first pipe section 21) of the anti-condensation pipe 2 that extends into the thermal insulation space 103 is basically folded only along the direction x and the direction y to be disposed around the convex hull 15, and is maintained at a same height along the direction z. This helps reduce arrangement complexity of the anti-condensation pipe 2, and improves assembly efficiency.

[0109] In a variable example, referring to FIG. 13, there is also a non-zero height difference between the first portion 211 and the second portion 212, and the height difference between the first portion 211 and the second portion 212 matches the height difference between the first area 143 and the second area 144. In other words, during laying, corresponding step setting is also performed on the first pipe section 21 in cooperation with the shape of the outer contour of the convex hull 15. For example, a distance between the first portion 211 and the first area 143 may be approximately equal to a distance between the second portion 212 and the second area 144. Therefore, the first pipe section 21 is disposed attaching to an outer contour of the mounting portion 142, to further optimize an anti-condensation effect in an area that is at the top of the refrigeration appliance 1 and that corresponds to the mounting portion 142.

[0110] In a specific implementation, referring to FIG. 2 to FIG. 9, the projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 bypasses the flipping beam 14, and extends, on a rear side of the flipping beam 14, from one side of the flipping beam 14 to the other side of the flipping beam 14. Therefore, the condensation problem in an area that is on the top surface 102a of the outer housing 102 and that directly faces the flipping beam 14 is specifically resolved.

[0111] In a specific implementation, the anti-condensation pipe 2 may be a metal pipe, and the anti-condensation pipe 2 is connected to the compressor compartment and is in communication with a refrigeration cycle. Therefore, the heat generated during use of the refrigeration appliance 1 is used to prevent condensation on an outer surface of the refrigeration appliance 1.

[0112] In a specific implementation, in a normal condition, after the first door 11 is opened, the flipping beam 14 automatically rotates to the first position without interfering with the second door 12. However, the user may perform a misoperation to rotate the flipping beam 14 to the second position. In this specific implementation, even if the flipping beam 14 is at the second position, the protruding member 192 may enter the guide groove 191 to close the first door 11.

[0113] Specifically, the protruding member 192 may move relative to the first door 11 along a direction of a pivot axis of the first door 11. For example, the protruding member 192 may move relative to the flipping beam 14, an end portion of the flipping beam 14 may be provided with a cut-out 194 (as shown in FIG. 3) for mounting the protruding member 192, and the protruding member 192 is guided in the cut-out 194 in a manner of being vertically displaced. A sleeve is disposed on an inner side of the protruding member 192. The sleeve is sleeved on a pin 195 located in the flipping beam 14. The first guide member 19 may further include a coil spring that is located on the pin 195 and that is configured to support the protruding member 192. When no external force is applied, the coil spring may push the protruding member 192 upward.

[0114] Further, when the flipping beam 14 at the second position is close to the body 10, a guide slope of the protruding member 192 is slightly lower than a frontmost side on a tail end surface of a front surface (namely, a surface on which the entry 191a is located, which is flush with the butting surface 14a, as shown in FIG. 7) of the guide base 141 along a longitudinal direction on a side close to the body 10. Therefore, the protruding member 192 and the guide base 141 overlap along the longitudinal direction. If the first door 11 continues to be pushed, the tail end surface of the protruding member 192 is press-connected to the front surface of the guide base 141 to compress a rotating spring, and the protruding member 192 supported by the rotating spring moves downward until the protruding member 192 passes over the front surface of the guide base 141 and enters the guide groove 191. After a state of being press-connected to the front surface of the guide base 141 is released, the protruding member 192 moves toward a bottom wall of the guide groove 191 under support of the rotating spring. The protruding member 192 and the front surface of the guide base 141 overlap along a direction perpendicular to the butting surface 14a, to prevent the protruding member 192 from passing over the front surface of the guide base 141 and exiting the guide groove 191.

[0115] In this process, that is, when the flipping beam 14 is at the second position and the first door 11 is closed, the protruding member 192 does not rotate relative to the first door 11, but only performs linear movement relative to the first door 11. Therefore, when the flipping beam 14 is at the second position and the first door 11 is closed, an angle between the flipping beam 14 and the first door 11 remains unchanged, and the flipping beam 14 is horizontally pushed into the body 10.

Embodiment Construction

[0050]A guide mechanism needs to be fixed at a top of a refrigerator by using a fixing member. The fixing member passes through a top wall of a liner of the refrigerator and extends into a thermal insulation layer. This may affect thermal insulation performance of the thermal insulation layer. In addition, in some refrigerators, to improve aesthetics of a storage compartment, the top wall of the liner protrudes upward to form a mounting portion. The guide mechanism is mounted on the mounting portion, so that the top wall of the storage compartment is flat when viewed from the front. However, that causes a thinner thermal insulation layer and poorer thermal insulation performance. Practices show that for either of the foregoing two situations, heat generated by a conventional anti-condensation pipe disposed on a front side of the top cannot increase a temperature of an area at the top of the refrigerator above a dew point temperature, causing a condensation phenomenon still to occur ...

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the priority, under 35 U.S.C. § 119, of Chinese Patent Application CN 202411392533.9, filed Sep. 30, 2024; the prior application is herewith incorporated by reference in its entirety.FIELD OF THE INVENTION

[0002] Embodiments of the present invention relate to the field of refrigeration appliance technologies, and specifically, to a refrigeration appliance.BACKGROUND OF THE INVENTION

[0003] In a multi-door refrigerator and a side-by-side refrigerator, a flipping beam is usually disposed between two doors that are configured to jointly open and close the same storage compartment, and the flipping beam is pivotally connected to one of the two doors and may pivot around the door as the door is opened and closed. A guide mechanism is further disposed in the refrigerator to guide the flipping beam to move based on a stipulated trajectory, to ensure smoothness of movement of the flipping beam.SUMMARY OF THE INVENTION

[0004] It is accordingly an object of the invention to provide an improved refrigeration appliance, which overcomes the disadvantages of the heretofore-known appliances of this general type.

[0005] With the foregoing and other objects in view there is provided, in accordance with the invention, a refrigeration appliance, including a body including an inner housing, an outer housing located on an outer side of the inner housing, and a thermal insulation space located between the inner housing and the outer housing, where the inner housing defines at least one open storage compartment; a first door including a first side and a second side that are opposite to each other, where the first side of the first door is rotatably connected to the body; a second door disposed in parallel with the first door to jointly close one storage compartment; a flipping beam pivotally connected to the second side of the first door, where the flipping beam is suitable for rotating between a first position at which the flipping beam is located when the first door is opened and a second position at which the flipping beam is located when the first door is closed, and a gap between the first door and the second door may be sealed when the flipping beam is at the second position; and a guide base, disposed on the inner housing, and cooperating with the flipping beam to guide the flipping beam to rotate in a process of opening and closing the first door.

[0006] The refrigeration appliance further includes an anti-condensation pipe including a first pipe section extending from a front side of the inner housing into the thermal insulation space, where the first pipe section extends close to the guide base.

[0007] The guide base is disposed at a top of a refrigerator and more or less needs to occupy a space that originally belongs to a thermal insulation layer, causing the thermal insulation layer at the top of the refrigerator to become thinner. However, a thinner thermal insulation layer indicates poorer thermal insulation performance. In that case, a temperature of an area at the top of the refrigerator that is directly above the guide base is prone to be lower than a dew point temperature, and consequently, condensation occurs.

[0008] In the solution in this implementation, the foregoing technical problem is resolved through an arrangement path of the anti-condensation pipe at the top of the refrigeration appliance. The anti-condensation pipe is disposed near the guide base in the thermal insulation space, so that a temperature around the guide base can be more effectively increased, to relieve and even eliminate a condensation phenomenon at the top of the refrigerator. Specifically, the first pipe section of the anti-condensation pipe is purposely routed below an area on a top surface of the outer housing in which condensation is prone to occur, and the route covers the condensation area. The anti-condensation pipe generates heat during operation of the refrigeration appliance. The heat is transmitted to the top surface of the outer housing, to increase a temperature of the top surface and enable the temperature of the top surface to be higher than the dew point temperature, thereby reliably resolving the condensation problem in the area that is at the top of the refrigeration appliance and that corresponds to the guide base. For a built-in refrigerator, an effect of relieving condensation at the top of the refrigerator by using the solution in this implementation is particularly significant. Further, in comparison to a solution to the condensation problem in which a thickness of the thermal insulation space at the top is increased by adjusting an arrangement position of another component in the refrigeration appliance, sacrificing a volume, and the like, structural complexity of this implementation is low, modification to the another component in the refrigeration appliance is small, and the volume of the storage compartment is not affected.

[0009] In addition, the first pipe section avoids a space on a front side of the inner housing, so that a groove portion does not need to be formed in an area that is on the front side of the inner housing and that corresponds to the guide base to accommodate the anti-condensation pipe, and a structure of the front side of the inner housing is simpler. In this way, it is conducive to improving a manufacturing yield during thermoforming of the inner housing, and improving product quality.

[0010] Optionally, a projection of the first pipe section along a height direction of the refrigeration appliance is disposed around the guide base. Therefore, the first pipe section is disposed around the guide base in the thermal insulation space, to ensure that heat of the anti-condensation pipe can be transmitted, with a low loss, to an area that is on the top surface of the outer housing and that directly faces the guide base, to relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance, especially in the area in which the guide base is located.

[0011] Optionally, the projection of the first pipe section along the height direction of the refrigeration appliance at least partially falls within a range of a projection of the guide base along the height direction of the refrigeration appliance. Therefore, the first pipe section is at least partially located between the guide base and the top surface of the outer housing, to mainly resolve the condensation problem in the area that is on the top surface of the outer housing and that directly faces the guide base.

[0012] Optionally, a convex hull protrudes from the inner housing into the thermal insulation space, to form a sunken mounting portion on a top wall of the inner housing, and the guide base is mounted on the mounting portion. The projection of the first pipe section along the height direction of the refrigeration appliance is disposed around the convex hull. The configuration in which the inner housing protrudes upward to form the mounting portion for mounting the guide base enables the guide base to be flush with the top wall of the inner housing. The top of the storage compartment is flat and aesthetical when viewed from the front. The thermal insulation space needs to be occupied for disposition of the convex hull, so that a thickness of the thermal insulation space between the convex hull and the top surface of the outer housing is obviously thinner than a thickness of the thermal insulation space in another area at the top of the refrigeration appliance. Therefore, in the solution in this implementation, the anti-condensation pipe is specifically disposed around the convex hull in the thermal insulation space, to reliably resolve the condensation problem in the area that is on the top surface of the outer housing and that corresponds to the guide base.

[0013] Optionally, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, and the guide base is mounted on the mounting portion. The projection of the first pipe section along the height direction of the refrigeration appliance at least partially falls within a range of a projection of the convex hull along the height direction of the refrigeration appliance. Therefore, the first pipe section at least partially passes through an area in which the thermal insulation space at the top of the refrigeration appliance is thin, specifically to resolve the condensation problem in the area that is on the top surface of the outer housing and that directly faces the guide base.

[0014] Optionally, the first pipe section is located between the convex hull and the top surface of the outer housing along the height direction of the refrigeration appliance. Therefore, the anti-condensation pipe passes above the convex hull, to ensure that the heat reliably covers an area that is on the top surface of the outer housing and that directly faces the convex hull, to better resolve the condensation problem at the top of the refrigeration appliance.

[0015] Optionally, the first pipe section extends, on a rear side of the convex hull, from one side of the convex hull to the other side of the convex hull. Therefore, the anti-condensation pipe is purposely routed below the area on the top surface of the outer housing in which condensation is prone to occur, and the route covers the condensation area, to reliably relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance.

[0016] Optionally, along the height direction of the refrigeration appliance, a first distance between the first pipe section and the top surface of the outer housing is less than a second distance between the first pipe section and the top wall of the inner housing. Therefore, the first pipe section of the anti-condensation pipe that extends into the thermal insulation space is disposed as close as possible to the top surface of the outer housing, to more effectively increase the temperature of the top surface and enable the temperature of the top surface to be higher than the dew point temperature, thereby resolving the condensation problem at the top of the refrigeration appliance.

[0017] Optionally, a ratio of the first distance to the second distance is 2:3. Therefore, the first pipe section is disposed as close as possible to the top surface of the outer housing, to ensure that the heat is radiated to the top surface with a low loss.

[0018] Optionally, a value of the first distance ranges from 10 mm to 20 mm. Optionally, a value of the second distance ranges from 20 mm to 30 mm.

[0019] Optionally, an edge of the top wall of the inner housing is folded toward the outer housing to form a first flange, an edge of the outer housing is folded to form an open groove toward the top wall, and the first flange extends into the groove, to enable the inner housing and the outer housing to be connected at the top and form an accommodating portion. The anti-condensation pipe includes a second pipe section that extends outside the thermal insulation space, the first pipe section is in communication with the second pipe section, and the second pipe section is accommodated in the accommodating portion. Therefore, the anti-condensation pipe is disposed along an entire width direction of the top of the refrigeration appliance, and most sections (for example, the second pipe section) of the anti-condensation pipe are disposed on the front side of the inner housing without damaging a structure of the inner housing. For the area in which the guide base is located, the anti-condensation pipe passes through the first flange and is laid in the thermal insulation space, to better increase a temperature near the guide base, so that a condensation phenomenon on the top surface of the outer housing and a condensation phenomenon in the front of the outer housing can be greatly improved. Further, after the door is opened, the anti-condensation pipe and the first flange are invisible to the outside, so that an appearance of the refrigeration appliance is more aesthetical.

[0020] Optionally, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, the guide base is mounted on the mounting portion, and the first pipe section is disposed at least along a side of the mounting portion away from the first flange. Therefore, the first pipe section extends deep enough into the thermal insulation space, to ensure that the generated heat is sufficient to cover an area in which the mounting portion is located, so as to relieve the condensation phenomenon at the top of the refrigeration appliance.

[0021] Optionally, the second pipe section extends along the width direction of the refrigeration appliance to be flush with two ends of the first flange. Therefore, the anti-condensation pipe is disposed in the front of the top of the refrigeration appliance along the entire width direction, to effectively resolve the condensation problem in the front of the outer housing.

[0022] Optionally, along the height direction of the refrigeration appliance, the first pipe section and the second pipe section are located at a same height. Therefore, mounting is convenient. After extending along the first flange to form the second pipe section, the anti-condensation pipe is directly folded backward to enter the thermal insulation space, and then the anti-condensation pipe is folded around the mounting portion through a shortest path and a simplest operation, to form the first pipe section.

[0023] Optionally, the first pipe section extends in a U shape. Therefore, the U-shaped first pipe section can surround at least three surfaces of the guide base, to omnidirectionally relieve the condensation phenomenon in the area that is at the top of the refrigeration appliance and that corresponds to the guide base.

[0024] Optionally, the first flange includes a groove portion. The groove portion is sunken toward the thermal insulation space, to accommodate the second pipe section, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, and the guide base is mounted on the mounting portion. A projection of the mounting portion on the first flange and the groove portion do not overlap along a depth direction of the refrigeration appliance. Therefore, the anti-condensation pipe keeps away from the first flange located on a front side of the guide base, and instead bypasses it through the thermal insulation space (namely, a section in which the first pipe section is located), so that the groove portion does not need to be provided in an area that is of the first flange and that is located on the front side of the guide base, to reduce a probability that a quality problem, such as a wrinkle, occurs in the area on the front side of the guide base during thermoforming of the inner housing, and improve a product yield.

[0025] Optionally, the first flange is provided with a first through hole through which the anti-condensation pipe extends into the thermal insulation space and a second through hole through which the anti-condensation pipe extends out of the thermal insulation space, and the first through hole and the second through hole are provided adjacent to the guide base and are respectively located on two sides of the guide base. Therefore, after extending for a distance along the front sides of the inner housing and the outer housing, the anti-condensation pipe enters the thermal insulation space through the first through hole, extends for a distance around the guide base, extends out of the thermal insulation space through the second through hole, and then continues to extend along the front sides of the inner housing and the outer housing. In this way, the anti-condensation pipe is disposed both in the front of and above the top of the refrigeration appliance to resolve the condensation problem.

[0026] Optionally, the first flange, corresponding to the guide base, includes a sealing portion that protrudes into the thermal insulation space. Therefore, disposition of the sealing portion can reduce an assembly gap between an area that is of the first flange and that corresponds to the guide base and the groove, to facilitate, during assembly, insertion of filler to block the gap to prevent leakage, and improve sealing performance of an area in front of the guide base.

[0027] Optionally, the first pipe section includes a first part that extends parallel to the first flange, where a distance between the first part and the first flange is greater than a distance between the first pipe section and the top surface of the outer housing. Therefore, the first pipe section is disposed as close as possible to the top surface of the outer housing, and extends as far as possible into the thermal insulation space along the depth direction of the refrigeration appliance, to enable a heat radiating area of the first pipe section to cover more areas at the top of the refrigeration appliance, especially, an area corresponding to the guide base.

[0028] Optionally, the distance between the first part and the first flange is greater than a distance between the first pipe section and the top wall of the inner housing. Therefore, the first pipe section extends as far as possible into the thermal insulation space along the depth direction of the refrigeration appliance, to enable the heat radiating area of the first pipe section to cover more areas at the top of the refrigeration appliance, especially, the area corresponding to the guide base.

[0029] Optionally, the convex hull protrudes from the inner housing into the thermal insulation space, to form the sunken mounting portion on the top wall of the inner housing, the guide base is mounted on the mounting portion, the mounting portion includes a first area and a second area that are disposed in parallel along the width direction of the refrigeration appliance, and the first pipe section includes a first portion disposed around the first area and a second portion disposed around the second area. Along the height direction of the refrigeration appliance, there is a non-zero height difference between the first area and the second area and there is a non-zero height difference between the first portion and the second portion, and the height difference between the first portion and the second portion matches the height difference between the first area and the second area. Therefore, the first pipe section is disposed attaching to an outer contour of the mounting portion, to further optimize an anti-condensation effect in an area that is at the top of the refrigeration appliance and that corresponds to the mounting portion.

[0030] Optionally, the guide base basically does not protrude from the top wall of the inner housing in the storage compartment. Therefore, there is no additional concave-convex structure at the top of the storage compartment (namely, the top wall of the inner housing), and after the door is opened, an appearance of the front of the storage compartment is more aesthetical.

[0031] Optionally, the refrigeration appliance further includes a first fixing member and a second fixing member. The first fixing member is fixed on the top wall of the inner housing and extends into the thermal insulation space, and the second fixing member passes through the guide base and is fixed on the first fixing member. In this way, the guide base is reliably mounted in the refrigeration appliance by using the first fixing member and the second fixing member, and in cooperation with the first pipe section, a part of the first fixing member that is located in the thermal insulation space is prevented from affecting the anti-condensation effect at the top of the refrigeration appliance.

[0032] Optionally, the flipping beam includes a first guide member, one of the guide base and the first guide member includes a guide groove, and the other of the guide base and the first guide member includes a protruding member suitable for moving in the guide groove. Therefore, through cooperation between the guide groove and the protruding member, the flipping beam is guided to rotate based on a preset trajectory as the door is opened and closed.

[0033] Optionally, the projection of the first pipe section along the height direction of the refrigeration appliance bypasses the flipping beam, and extends, on a rear side of the flipping beam, from one side of the flipping beam to the other side of the flipping beam. Therefore, the condensation problem in an area that is on the top surface of the outer housing and that directly faces the flipping beam is specifically resolved.

[0034] Other features which are considered as characteristic for the invention are set forth in the appended claims.

[0035] 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.

[0050] A guide mechanism needs to be fixed at a top of a refrigerator by using a fixing member. The fixing member passes through a top wall of a liner of the refrigerator and extends into a thermal insulation layer. This may affect thermal insulation performance of the thermal insulation layer. In addition, in some refrigerators, to improve aesthetics of a storage compartment, the top wall of the liner protrudes upward to form a mounting portion. The guide mechanism is mounted on the mounting portion, so that the top wall of the storage compartment is flat when viewed from the front. However, that causes a thinner thermal insulation layer and poorer thermal insulation performance. Practices show that for either of the foregoing two situations, heat generated by a conventional anti-condensation pipe disposed on a front side of the top cannot increase a temperature of an area at the top of the refrigerator above a dew point temperature, causing a condensation phenomenon still to occur at the top of the refrigerator. The condensation problem is especially prominent in a built-in refrigerator. Because a gap between a top of the built-in refrigerator and a cabinet is very small, condensation is more likely to occur.

[0051] In addition, in a conventional refrigerator, a groove portion needs to be provided on a flange of the liner to accommodate the anti-condensation pipe. However, most liners are formed by thermoforming. Regardless of disposition of the foregoing fixing member or the mounting portion that protrudes upward, if the groove portion further needs to be formed at the flange in front of the fixing member or the mounting portion, a quality problem such as a wrinkle is prone to occur during thermoforming, resulting in a lower manufacturing yield of the liner.

[0052] In order to resolve the foregoing technical problem, an embodiment of the present invention provides a refrigeration appliance, including: a body, including an inner housing, an outer housing located on an outer side of the inner housing, and a thermal insulation space located between the inner housing and the outer housing, where the inner housing defines at least one open storage compartment; a first door, including a first side and a second side that are opposite to each other, where the first side of the first door is rotatably connected to the body; a second door, disposed in parallel with the first door to jointly close one storage compartment; a flipping beam, pivotally connected to the second side of the first door, where the flipping beam is suitable for rotating between a first position at which the flipping beam is located when the first door is opened and a second position at which the flipping beam is located when the first door is closed, and a gap between the first door and the second door may be sealed when the flipping beam is at the second position; and a guide base, disposed on the inner housing, and cooperating with the flipping beam to guide the flipping beam to rotate in a process of opening and closing the first door. The refrigeration appliance further includes: an anti-condensation pipe, including a first pipe section extending from a front side of the inner housing into the thermal insulation space, where the first pipe section extends close to the guide base.

[0053] In the solution in this implementation, the foregoing problem is resolved by optimizing an arrangement path of the anti-condensation pipe at a top of the refrigeration appliance. The anti-condensation pipe is disposed near the guide base in the thermal insulation space, so that a temperature around the guide base can be more effectively increased, to relieve and even eliminate a condensation phenomenon at the top of the refrigerator. Specifically, the first pipe section of the anti-condensation pipe is purposely routed below an area on a top surface of the outer housing in which condensation is prone to occur, and the route covers the condensation area. The anti-condensation pipe generates heat during operation of the refrigeration appliance. The heat is transmitted to the top surface of the outer housing, to increase a temperature of the top surface and enable the temperature of the top surface to be higher than a dew point temperature, thereby reliably resolving the condensation problem in an area that is at the top of the refrigeration appliance and that corresponds to the guide base. For a built-in refrigerator, an effect of relieving condensation at the top of the refrigerator by using the solution in this implementation is particularly significant. Further, in comparison to a solution to the condensation problem in which a thickness of the thermal insulation space at the top is increased by adjusting an arrangement position of another component in the refrigeration appliance, sacrificing a volume, and the like, structural complexity of the solution in this implementation is low, modification to the another component in the refrigeration appliance is small, and the volume of the storage compartment is not affected.

[0054] In addition, the first pipe section avoids a space on a front side of the inner housing, so that a groove portion does not need to be formed in an area that is on the front side of the inner housing and that corresponds to the guide base to accommodate the anti-condensation pipe, and a structure of the front side of the inner housing is simpler. In this way, it is conducive to improving a manufacturing yield during thermoforming of the inner housing, and improving product quality.

[0055] In order to make the foregoing objectives, features, and advantages of the present invention more comprehensible, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0056] Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen a diagrammatic illustration of a refrigeration appliance 1 according to an embodiment of the present invention. FIG. 2 to FIG. 5 exemplarily show an internal structure of a top of the refrigeration appliance 1 from different perspectives. In order to show the internal structure of the refrigeration appliance 1 more clearly, a top surface 102a of an outer housing 102 is omitted in FIG. 3 and FIG. 5, and a first door 11 and a second door 12 are omitted in FIG. 4.

[0057] The refrigeration appliance 1 may be a refrigerator, a refrigerated cabinet, a wine cooler, and the like. FIG. 1 is exemplarily shown by using a multi-door refrigerator as an example. During actual application, a configuration of a guide base and an anti-condensation pipe 2 for the top of the refrigeration appliance 1 in this implementation may also be applicable to various forms of refrigerators having a left door and a right door, such as a cross door refrigerator, a French door refrigerator, and a side-by-side refrigerator.

[0058] For ease of description, in the solution in this implementation, a width direction of the refrigeration appliance 1 is denoted as a direction x, a depth direction of the refrigeration appliance 1 is denoted as a direction y, and a height direction of the refrigeration appliance 1 is denoted as a direction z. In the solution in this implementation, a front direction and a rear direction respectively refer to the direction y and an opposite direction of the direction y. A front or a front side refers to a direction along which the refrigeration appliance 1 faces a user when the refrigeration appliance 1 is in use, and a rear or a rear side refers to a direction along which the refrigeration appliance 1 faces away from the user when the refrigeration appliance 1 is in use. In the solution in this implementation, an up direction and a down direction respectively refer to the direction z and an opposite direction of the direction z. A top refers to a direction that is more up along a gravity direction when the refrigeration appliance 1 is in use, and a bottom refers to a direction that is in contact with or closest to the ground when the refrigeration appliance is in use.

[0059] Specifically, referring to FIG. 1 to FIG. 6, the refrigeration appliance 1 may include a body 10, including an inner housing 101, an outer housing 102 located on an outer side of the inner housing 101, and a thermal insulation space 103 located between the inner housing 101 and the outer housing 102. For example, the inner housing 101 may include a top wall 101a and a bottom wall (not shown in the figure) that are opposite to each other along the direction z, and a pair of side walls 101b that are opposite to each other along the direction x and a rear wall (not shown in the figure). The top wall 101a, the bottom wall, the pair of side walls 101b, and the rear wall jointly enclose an open storage space that faces forward. Further, the outer housing 102 may include the top surface 102a and a bottom surface (not shown in the figure) that are opposite to each other along the direction z, and a pair of side surfaces 102b that are opposite to each other along the direction x and a rear surface 102c. The top surface 102a, the bottom surface, the side surfaces 102b, and the rear surface 102c jointly enclose an open accommodating space that faces forward, and the inner housing 101 is accommodated in the accommodating space. Further, the thermal insulation space 103 filled with a thermal insulation material may be included between the outer housing 102 and the inner housing 101. A thermal insulation layer formed by the thermal insulation space has an effect of isolating heat, to ensure a good refrigerating / freezing effect of the storage space.

[0060] Further, the inner housing 101 defines at least one open storage compartment 104. For example, the foregoing storage space may be divided into at least one storage compartment 104 along the direction z and / or the direction x. Using a refrigerator as an example, the storage compartment 104 may be, for example, a freezing compartment, a refrigerating compartment, or a temperature-variable compartment. Each storage compartment 104 may be configured with at least one door to open or close the storage compartment 104. The door may be a hinge door or a drawer-type door. FIG. 1 and FIG. 6 are exemplarily shown by using an example in which two doors are configured to jointly open or close one storage compartment 104.

[0061] Further, the refrigeration appliance 1 may include the first door 11, including a first side 11a and a second side 11b that are opposite to each other along the direction x, and the first side 11a of the first door 11 is rotatably connected to the body 10. Further, the refrigeration appliance 1 may further include the second door 12 that is disposed in parallel with the first door 11 to jointly close one storage compartment 104. For either of the first door 11 and the second door 12, the door may include a thermal insulation layer 112 filled with a thermal insulation material. When the first door 11 and the second door 12 are configured to close the storage compartment 104, the thermal insulation layer 112 has an effect of isolating heat, to ensure a good refrigerating / freezing effect of the storage compartment 104. For either of the first door 11 and the second door 12, the door may include a front panel 110, a rear panel 113 that faces the body 10 when the door is closed, and a frame 114 disposed along a periphery of the door. The thermal insulation layer 112 is located between the front panel 110 and the rear panel 113. In some embodiments, the front panel 110 forms at least a part of a front boundary of the thermal insulation layer 112, so that the thermal insulation material is in contact with a rear side of the front panel 110. In some other embodiments, another door panel may be further disposed on the rear side of the front panel 110. The front panel 110 may be a metal door housing, a glass plate, or a ceramic plate. In some embodiments, the first door 11 and the second door 12 may be respectively movably connected to the body 10 through a hinge 13. For example, the first side 11a of the first door 11 is connected to the body 10 through the hinge 13 on two sides along the direction z.

[0062] A door handle 122 may be disposed on one of adjacent sides of the first door 11 and the second door 12. For example, referring to FIG. 2, the door handle 122 may be disposed on a side that is of the second door 12 and that is close to the second side 11b of the first door 11. The user may open the second door 12 by holding the door handle 122, and then open the first door 11.

[0063] A shelf 121 may be disposed on the rear panel 113 of either of the first door 11 and the second door 12, for the user to store objects. The shelf 121 may be, for example, a bottle shelf or an egg shelf.

[0064] When both the first door 11 and the second door 12 are closed, there is a gap between the second side 11b of the first door 11 and the second door 12. In order to seal the gap, the refrigeration appliance 1 may further include a flipping beam 14 that is pivotally connected to the second side 11b of the first door 11. The flipping beam 14 is suitable for rotating between a first position at which the flipping beam 14 is located when the first door 11 is opened and a second position at which the flipping beam 14 is located when the first door 11 is closed, and the gap between the first door 11 and the second door 12 may be sealed when the flipping beam 14 is at the second position.

[0065] For example, when the first door 11 is in an open state shown in FIG. 6, the flipping beam 14, which has a cross section that is in a shape of a rectangle, may be at the first position, that is, the flipping beam 14 is returned to a position at which a narrow side faces the body 10. In this case, the flipping beam 14 does not extend out of the second side 11b of the first door 11 along a side direction, so that when the second door 12 is in a closed state, if the first door 11 is closed, the flipping beam 14 can pass over the second door 12. Further, when the first door 11 is closed, the flipping beam 14 enters the inside of the body 10 and rotates around a vertical axis in this process, so that after entering the body 10, a butting surface 14a formed on a wide side of the flipping beam 14 is flush with a front side (for example, a first flange 18) of the inner housing 101 (as shown in FIG. 3). In this case, the flipping beam 14 is at the second position. The first door 11 and the second door 12 are each provided with a door seal member 111 around the rear panel 113. When the first door 11 and the second door 12 are configured to close the storage compartment 104, the door seal member 111 abuts against the first flange 18. At the second position, the first flange 18 and the butting surface 14a form a support surface that can cover the gap between the first door 11 and the second door 12, and the door seal members 111 of the first door 11 and the second door 12 abut against the support surface in a sealing manner, as shown in FIG. 2. Further, the refrigeration appliance 1 may further include a guide base 141, which is disposed on the inner housing 101, and cooperates with the flipping beam 14 to guide the flipping beam 14 to rotate in a process of opening and closing the first door 11. The guide base 141 may be disposed at the top of the refrigeration appliance 1 and disposed close to an opening of the storage compartment 104. In some embodiments, referring to FIG. 3, FIG. 6, FIG. 7, and FIG. 9, the flipping beam 14 may include a first guide member 19, one of the guide base 141 and the first guide member 19 may include a guide groove 191, and the other of the guide base 141 and the first guide member 19 includes a protruding member 192 suitable for moving in the guide groove 191. The protruding member 192 may have a cross section in an arc shape, and may move in the guide groove 191 to drive the flipping beam 14 to rotate. The guide groove 191 is in a curved shape, and has an entry 191a facing the protruding member 192.

[0066] When the first door 11 is closed, an end that is close to the narrow side and that is of the protruding member 192 on the flipping beam 14 at the first position enters the entry 191a of the guide groove 191, and an edge of a convex side of the protruding member 192 starts to come into contact with a groove wall of the guide groove 191. As the first door 11 is further closed, the edge of the convex side of the protruding member 192 slides along the guide groove 191, to drive the flipping beam 14 to pivot around the vertical axis until the flipping beam 14 is at the second position. In this case, the butting surface 14a is flush with the first flange 18. Similarly, when the first door 11 is opened, the protruding member 192 also rotates in the guide groove 191 to drive the flipping beam 14 to rotate to the first position, so that the flipping beam 14 can pass through the closed second door 12, and the first door 11 can be opened when the second door 12 is closed. Therefore, through cooperation between the guide groove 191 and the protruding member 192, the flipping beam 14 is guided to rotate based on a preset trajectory as the door (for example, the first door 11) is opened and closed.

[0067] Further, the refrigeration appliance 1 may further include the anti-condensation pipe 2, including a first pipe section 21 that extends from the front side of the inner housing 101 into the thermal insulation space 103, and the first pipe section 21 extends close to the guide base 141. For example, referring to FIG. 1, the anti-condensation pipe 2 may be continuously disposed from a compressor compartment (not shown in the figure) disposed at the bottom of the body 10 to the top of the refrigeration appliance 1 along the thermal insulation space 103 between the pair of side walls 101b and the pair of side surfaces 102b. The anti-condensation pipe 2 may be connected to a condenser (not shown in the figure) of the refrigeration appliance 1, and the anti-condensation pipe 2 may include a refrigerant at a specific temperature. Further, the anti-condensation pipe 2 may extend and be disposed around the opening of each storage compartment 104.

[0068] Referring to FIG. 1, FIG. 6, and FIG. 7, at the top of the refrigeration appliance 1, the anti-condensation pipe 2 extends from one end of the inner housing 101 along the direction x against the front side of the inner housing 101 to a position near the guide base 141 along the direction x, passes through the inner housing 101 and enters the thermal insulation space 103, extends around the guide base 141 for a distance (namely, the first pipe section 21) in the thermal insulation space 103, extends out of the inner housing 101, and continues to extend along the front side of the inner housing 101 to the other end of the inner housing 101 along the direction x.

[0069] Based on the above, in the solution in this implementation, an arrangement path of the anti-condensation pipe 2 at the top of the refrigeration appliance 1 is optimized. The anti-condensation pipe 2 is disposed near the guide base 141 in the thermal insulation space 103, so that a temperature around the guide base 141 can be more effectively increased, to relieve and even eliminate a condensation phenomenon at the top of the refrigerator. Specifically, the first pipe section 21 of the anti-condensation pipe 2 is purposely routed below an area on the top surface 102a of the outer housing 102 in which condensation is prone to occur, and the route covers the condensation area. The anti-condensation pipe 2 generates heat during operation of the refrigeration appliance 1. The heat is transmitted to the top surface 102a of the outer housing 102, to increase a temperature of the top surface 102a and enable the temperature of the top surface 102a to be higher than a dew point temperature, so as to reliably resolve the condensation problem in an area that is at the top of the refrigeration appliance 1 and that corresponds to the guide base 141. For a built-in refrigerator, an effect of relieving condensation at the top of the refrigerator by using the solution in this implementation is particularly significant. Further, structural complexity of the solution in this implementation is low, modification to another component in the refrigeration appliance 1 is small, and a volume of the storage compartment 104 is not affected.

[0070] In addition, the first pipe section 21 avoids a space on the front side of the inner housing 101, so that a groove portion 17 does not need to be formed in an area that is on the front side of the inner housing 101 and that corresponds to the guide base 141 to accommodate the anti-condensation pipe 2, and a structure of the front side of the inner housing 101 is simpler. In this way, it is conducive to improving a manufacturing yield during thermoforming of the inner housing 101, and improving product quality.

[0071] In a specific implementation, referring to FIG. 2 to FIG. 9, a projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 may be disposed around the guide base 141. Specifically, an outer contour of a projection of the guide base 141 along the direction z is approximately in a shape of a rectangle, and the first pipe section 21 is located at least near three sides of the rectangle. For example, the first pipe section 21 may be disposed close to a pair of opposite side wall surfaces of the guide base 141 along the direction x, and disposed close to a rear side wall surface of the guide base 141 along the direction y. Therefore, the first pipe section 21 is disposed around the guide base 141 in the thermal insulation space 103, to ensure that heat of the anti-condensation pipe 2 can be transmitted, with a low loss, to an area that is on the top surface 102a of the outer housing 102 and that directly faces the guide base 141, to relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance 1, especially in the area in which the guide base 141 is located.

[0072] Further, the projection of the first pipe section 21 along the direction z may be located outside the guide base 141, that is, the first pipe section 21 is disposed around the guide base 141 from a periphery. Therefore, the heat generated by the first pipe section 21 can be radiated to an area in the thermal insulation space 103 as much as possible along the depth direction of the refrigeration appliance 1, to optimize an anti-condensation effect at the top of the refrigeration appliance 1.

[0073] In a variable example, the projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 may at least partially fall within a range of a projection of the guide base 141 along the height direction (for example, the direction z) of the refrigeration appliance 1. In other words, the first pipe section 21 may at least partially pass above the guide base 141. Therefore, the first pipe section 21 is at least partially located between the guide base 141 and the top surface 102a of the outer housing 102, to mainly resolve the condensation problem in the area that is on the top surface 102a of the outer housing 102 and that directly faces the guide base 141.

[0074] In some embodiments, a relative position relationship between the projection of the first pipe section 21 along the direction z and the projection of the guide base 141 along the direction z may be determined based on a size of an area in which condensation is prone to occur at the top of the refrigeration appliance 1. For example, the size of the condensation area at the top of the refrigeration appliance 1 may be determined through an experiment. A larger condensation area indicates a smaller overlapping degree between the projection of the first pipe section 21 along the direction z and the projection of the guide base 141 along the direction z, and a larger degree to which the first pipe section 21 extends into the thermal insulation space 103 along an opposite direction of the direction y.

[0075] In some embodiments, a value of a distance between the first pipe section 41 and the front side (for example, the first flange 18) of the inner housing 101 along the direction y may range from 30 mm to 45 mm. For example, the distance between the first pipe section 41 and the first flange 18 along the direction y may be 38 mm.

[0076] In a variable example, the projection of the first pipe section 21 along the direction z may zigzag extend in an area surrounded by the projection of the guide base 141 along the direction z. Therefore, the condensation problem in the area that is at the top of the refrigeration appliance 1 and that corresponds to the guide base 141 can be further improved.

[0077] In a specific implementation, referring to FIG. 2 to FIG. 5 and FIG. 7 to FIG. 10, a convex hull 15 may protrude from the inner housing 101 into the thermal insulation space 103, to form a sunken mounting portion 142 on the top wall 101a of the inner housing 101. Specifically, the guide base 141 is mounted on the mounting portion 142.

[0078] Further, the guide base 141 basically does not protrude from the top wall 101a of the inner housing 101 in the storage compartment 104.

[0079] Therefore, there is no additional concave-convex structure at the top (namely, the top wall 101a of the inner housing 101) of the storage compartment 104, and after the door (for example, the first door 11 and the second door 12) is opened, an appearance of the front of the storage compartment 104 is aesthetical.

[0080] Further, the projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 may be disposed around the convex hull 15. For example, the projection of the first pipe section 21 along the direction z at least passes through three sides of the convex hull 15 whose outer contour is approximately in a shape of a rectangle. Alternatively, the projection of the first pipe section 21 along the direction z may at least partially fall within a range of a projection of the convex hull 15 along the direction z. The first pipe section 21 at least partially passes through an area in which the thermal insulation space 103 at the top of the refrigeration appliance 1 is thin, so that the condensation problem in the area that is on the top surface 102a of the outer housing 102 and that directly faces the guide base 141 is specifically resolved.

[0081] Therefore, the configuration in which the inner housing 101 protrudes upward to form the mounting portion 142 for mounting the guide base 141 enables the guide base 141 to be flush with the top wall 101a of the inner housing 101. The top of the storage compartment 104 is flat and aesthetical when viewed from the front. The thermal insulation space 103 needs to be occupied for disposition of the convex hull 15, so that a thickness of the thermal insulation space 103 between the convex hull 15 and the top surface 102a of the outer housing 102 is obviously thinner than a thickness of the thermal insulation space 103 in another area at the top of the refrigeration appliance 1. Therefore, in the solution in this implementation, the anti-condensation pipe 2 is specifically disposed around the convex hull 15 in the thermal insulation space 103, to reliably resolve the condensation problem in the area that is on the top surface 102a of the outer housing 102 and that corresponds to the guide base 141.

[0082] In some embodiments, the refrigeration appliance 1 may further include a first fixing member 145 and a second fixing member 146. The first fixing member 145 is fixed on the top wall 101a of the inner housing 101 and extends into the thermal insulation space 103, and the second fixing member 146 passes through the guide base 141 and is fixed on the first fixing member 145. Specifically, the convex hull 15 may be provided with a third through hole 147 for the first fixing member 145 to pass through, and the first fixing member 145 is screwed from the thermal insulation space 103 into the third through hole 147 and is at least partially screwed out from a side on which the mounting portion 142 is located. The guide base 141 is placed in the mounting portion 142, a mounting hole 193 provided on the guide base 141 is aligned with the third through hole 147, and the second fixing member 146 extends through the mounting hole 193 and is fixed on the first fixing member 145. The second fixing member 146 may be, for example, a screw. In this way, the guide base 141 is reliably mounted in the refrigeration appliance 1 by using the first fixing member 145 and the second fixing member 146, and in cooperation with the first pipe section 21, a part of the first fixing member 145 that is located in the thermal insulation space 103 is prevented from affecting the anti-condensation effect at the top of the refrigeration appliance 1.

[0083] In a specific implementation, the first pipe section 21 may be located between the convex hull 15 and the top surface 102a of the outer housing 102 along the height direction (for example, the direction z) of the refrigeration appliance 1. Therefore, the anti-condensation pipe 2 passes above the convex hull 15, to ensure that the heat reliably covers an area that is on the top surface 102a of the outer housing 102 and that directly faces the convex hull 15, to better resolve the condensation problem at the top of the refrigeration appliance 1.

[0084] In a specific implementation, referring to FIG. 2 to FIG. 9, the first pipe section 21 may extend, on a rear side of the convex hull 15, from one side of the convex hull 15 to the other side of the convex hull 15. Specifically, using a viewing angle in FIG. 8 as an example, the first pipe section 21 extends approximately in a U shape. After extending, along the opposite direction of the direction y, from a lower left corner of the convex hull 15 along the direction x and passing through a left side surface of the convex hull 15, the first pipe section 21 extends, along an opposite direction of the direction x, from a rear side of the convex hull 15, and passes through a rear side surface of the convex hull 15, and then extends through a right side surface of the convex hull 15 along the direction y.

[0085] Therefore, the anti-condensation pipe 2 is purposely routed below the area on the top surface 102a of the outer housing 102 in which condensation is prone to occur, and the route covers the condensation area, to reliably relieve and even eliminate the condensation phenomenon at the top of the refrigeration appliance 1. Further, the U-shaped first pipe section 21 can surround at least three surfaces of the guide base 141, to omnidirectionally relieve the condensation phenomenon in the area that is at the top of the refrigeration appliance 1 and that corresponds to the guide base 141.

[0086] In a specific implementation, referring to FIG. 4, along the height direction (for example, the direction z) of the refrigeration appliance 1, a first distance L1 between the first pipe section 21 and the top surface 102a of the outer housing 102 may be less than a second distance L2 between the first pipe section 21 and the top wall 101a of the inner housing 101. In other words, in comparison to the top wall 101a of the inner housing 101, the first pipe section 21 is disposed closer to the top surface 102a of the outer housing 102.

[0087] Therefore, the first pipe section 21 of the anti-condensation pipe 2 that extends into the thermal insulation space 103 is disposed as close as possible to the top surface 102a of the outer housing 102, to more effectively increase the temperature of the top surface 102a and enable the temperature of the top surface 102a to be higher than the dew point temperature, so as to resolve the condensation problem at the top of the refrigeration appliance 1.

[0088] In some embodiments, a ratio of the first distance L1 to the second distance L2 may be 2:3. A value of the first distance L1 may range from 10 mm to 20 mm. A value of the second distance L2 may range from 20 mm to 30 mm. For example, the first distance L1 may be 16 mm, and the second distance L2 may be 24 mm. Therefore, the first pipe section 21 is disposed as close as possible to the top surface 102a of the outer housing 102, to ensure that the heat is radiated to the top surface 102a with a low loss.

[0089] In a specific implementation, referring to FIG. 2 to FIG. 12, an edge of the top wall 101a of the inner housing 101 may be folded toward the outer housing 102 to form the first flange 18, and an edge of the outer housing 102 is folded to form an open groove 105 toward the top wall 101a. Specifically, walls that form the groove 105 may include a second wall 105b and a third wall 105c that are opposite to each other along the direction y, and a first wall 105a located between the second wall 105b and the third wall 105c. The third wall 105c is located in front of the second wall 105b along the direction y.

[0090] Further, the first flange 18 may include a groove portion 17, and the groove portion 17 is sunken toward the thermal insulation space 103.

[0091] Further, the first flange 18 extends into the groove 105, to enable the inner housing 101 and the outer housing 102 to be connected at the top and form an accommodating portion 16. After the first flange 18 is inserted into the groove 105, the groove portion 17 is attached to the second wall 105b. In addition, along the direction z, the third wall 105c abuts against an end wall formed by backward folding of the first flange 18, so that the outer housing 102 and the inner housing 101 is basically flush on a front side of the body 10.

[0092] Further, the anti-condensation pipe 2 may include a second pipe section 22 that extends outside the thermal insulation space 103, the first pipe section 21 is in communication with the second pipe section 22, and the second pipe section 22 is accommodated in the accommodating portion 16. For example, the groove portion 17 and the third wall 105c jointly enclose the accommodating portion 16 extending approximately along the direction x, to accommodate the second pipe section 22. During assembly, the second pipe section 22 may be first placed in the groove portion 17, and an opening of the groove portion 17 is adhered by using an aluminum foil tape to fix the second pipe section 22. Then, the first flange 18 is inserted into the groove 105, and the groove portion 17 and the third wall 105c cooperate to confine the second pipe section 22 in the accommodating portion 16.

[0093] Therefore, the anti-condensation pipe 2 is disposed along the entire width direction of the top of the refrigeration appliance 1, and most sections (for example, the second pipe section 22) of the anti-condensation pipe 2 are disposed on the front side of the inner housing 101 without damaging a structure of the inner housing. For the area in which the guide base 141 is located, the anti-condensation pipe 2 passes through the first flange 18 and is laid in the thermal insulation space 103, to better increase a temperature near the guide base 141, so that a condensation phenomenon on the top surface 102a of the outer housing 102 and a condensation phenomenon in the front of the outer housing 102 can be greatly improved. Further, after the door is opened, the anti-condensation pipe 2 and the first flange 18 are invisible to the outside, so that an appearance of the refrigeration appliance 1 is more aesthetical.

[0094] In a specific implementation, still referring to FIG. 2 to FIG. 9, the first pipe section 21 is disposed at least along a side of the mounting portion 142 away from the first flange 18. In other words, along the direction y, the mounting portion 142 is located between the first pipe section 21 and the first flange 18. Therefore, the first pipe section 21 extends deep enough into the thermal insulation space 103, to ensure that the generated heat is sufficient to cover an area in which the mounting portion 142 is located, so as to relieve the condensation phenomenon at the top of the refrigeration appliance 1. Further, the anti-condensation pipe 2 bypasses the first flange 18 in front of the mounting portion 142, so that the groove portion 17 does not need to be provided on the first flange 18 in the area, which is conducive to improving a yield rate during thermoforming of the inner housing 101.

[0095] In some embodiments, while extending generally along the direction x, the groove portion 17 is further slightly displaced up and down along the direction z, as shown in FIG. 3. Therefore, a labyrinth groove may be formed, which is convenient for subsequently sealing a gap (as shown in FIG. 12) between the groove portion 17 and the second wall 105b by using foam and an adhesive tape, and is conductive to better preventing foam leakage.

[0096] In a specific implementation, referring to FIG. 6 and FIG. 7, the second pipe section 22 extends along the width direction (for example, the direction x) of the refrigeration appliance 1 to be flush with two ends of the first flange 18. Therefore, the anti-condensation pipe 2 is disposed in the front of the top of the refrigeration appliance 1 along the entire width direction, to effectively resolve the condensation problem in the front of the outer housing 102.

[0097] In a specific implementation, referring to FIG. 5 and FIG. 7, along the height direction (for example, the direction z) of the refrigeration appliance 1, the first pipe section 21 and the second pipe section 22 may be located at a same height. In other words, when the anti-condensation pipe 2 is disposed at the top of the refrigeration appliance 1, in addition to extending along the direction x, the anti-condensation pipe 2 is folded only along the direction y and the opposite direction of the direction y to be disposed in the thermal insulation space 103, and there is no obvious folding and deformation along the direction z. Therefore, mounting is convenient. After extending along the first flange 18 to form the second pipe section 22, the anti-condensation pipe 2 is directly folded backward to enter the thermal insulation space 103, and then the anti-condensation pipe 2 is folded around the mounting portion 142 through a shortest path and a simplest operation, to form the first pipe section 21.

[0098] In a specific implementation, referring to FIG. 7 to FIG. 9, a projection of the mounting portion 142 on the first flange 18 and the groove portion 17 do not overlap along the depth direction (for example, the direction y) of the refrigeration appliance 1. Therefore, the anti-condensation pipe 2 keeps away from the first flange 18 located on a front side of the guide base 141, and instead bypasses it through the thermal insulation space 103 (namely, a section in which the first pipe section 21 is located), so that the groove portion 17 does not need to be provided in an area that is of the first flange 18 and that is located on the front side of the guide base 141, to reduce a probability that a quality problem, such as a wrinkle, occurs in the area on the front side of the guide base 141 during thermoforming of the inner housing 101, and improve a product yield.

[0099] In a specific implementation, referring to FIG. 2 to FIG. 12, the first flange 18 may be provided with a first through hole 181 through which the anti-condensation pipe 2 extends into the thermal insulation space 103 and a second through hole 182 through which the anti-condensation pipe extends out of the thermal insulation space 103. The first through hole 181 and the second through hole 182 are provided adjacent to the guide base 141 and are respectively located on two sides of the guide base 141 along the direction x. Further, the second wall 105b may be provided with a fourth through hole 106 corresponding to the first through hole 181 and a fifth through hole 107 corresponding to the second through hole 182.

[0100] Therefore, after extending for a distance along the front sides (namely, the groove portions 17) of the inner housing 101 and the outer housing 102, the anti-condensation pipe 2 enters the thermal insulation space 103 through the first through hole 181 (and the fourth through hole 106), extends for a distance around the guide base 141, extends out of the thermal insulation space 103 through the second through hole 182 (and the fifth through hole 107), and then continues to extend along the front sides (namely, the groove portions 17) of the inner housing 101 and the outer housing 102. In this way, the anti-condensation pipe 2 is disposed both in the front of and above the top of the refrigeration appliance 1 to resolve the condensation problem.

[0101] In some embodiments, the first through hole 181 and the second through hole 182 are preferably provided in an area in which the groove portion 17 is located, that is, the groove portion 17 is interrupted by the first through hole 181 and the second through hole 182. Therefore, referring to FIG. 12, structures of open holes on the inner housing 101 and the outer housing 102 for the anti-condensation pipe 2 to extend into and extend out of the thermal insulation space 103 are more complex, and during assembly, the open holes can be blocked only by inserting a small amount of filler, to avoid foam leakage.

[0102] In a specific implementation, referring to FIG. 2 to FIG. 4 and FIG. 7 to FIG. 10, the first flange 18 may include, corresponding to the guide base 141, a sealing portion 183 that protrudes toward the thermal insulation space 103.

[0103] Specifically, an extent to which the sealing portion 183 is sunken from the first flange 18 toward the thermal insulation space 103 may be less than an extent to which the groove portion 17 is sunken from the first flange 18 toward the thermal insulation space 103. Correspondingly, after the first flange 18 is inserted into the groove 105, a small and non-zero assembly gap may still exist between the sealing portion 183 and the second wall 105b. However, the assembly gap is at least smaller than an assembly gap between an area that is of the first flange 18 and that is not sunken toward the thermal insulation space 103 and the second wall 105b. Therefore, disposition of the sealing portion 183 can reduce an assembly gap between an area that is of the first flange 18 and that corresponds to the guide base 141 and the groove 105, to facilitate, during assembly, insertion of filler (for example, foam) to block the gap to prevent leakage, and improve sealing performance of an area in front of the guide base 141.

[0104] In a specific implementation, referring to FIG. 5 and FIG. 7 to FIG. 9, the first pipe section 21 may include a first part that extends parallel to the first flange 18. Further, the first pipe section 21 may further include a second part that extends perpendicular to the first flange 18, and the second part is located at two ends of the first part that are opposite to each other along the direction x, to form, together with the first part, the first pipe section 21 that extends in a U shape.

[0105] In some embodiments, a distance between the first part and the first flange 18 may be greater than the distance (namely, the first distance L1) between the first pipe section 21 and the top surface 102a of the outer housing 102. Therefore, the first pipe section 21 is disposed as close as possible to the top surface 102a of the outer housing 102, and extends as far as possible into the thermal insulation space 103 along the depth direction (for example, the direction y) of the refrigeration appliance 1, to enable a heat radiating area of the first pipe section 21 to cover more areas at the top of the refrigeration appliance 1, especially, an area corresponding to the guide base 141.

[0106] In some embodiments, the distance between the first part and the first flange 18 may be greater than the distance (namely, the second distance L2) between the first pipe section 21 and the top wall 101a of the inner housing 101. Therefore, the first pipe section 21 extends as far as possible into the thermal insulation space 103 along the depth direction (for example, the direction y) of the refrigeration appliance 1, to enable the heat radiating area of the first pipe section 21 to cover more areas of the top of the refrigeration appliance 1, especially, the area corresponding to the guide base 141.

[0107] In a specific implementation, referring to FIG. 5, FIG. 7, FIG. 8, and FIG. 10, the mounting portion 142 may include a first area 143 and a second area 144 that are disposed in parallel along the width direction (for example, the direction x) of the refrigeration appliance 1. Further, along the height direction (for example, the direction z) of the refrigeration appliance 1, there is a non-zero height difference between the first area 143 and the second area 144. For example, the first area 143 protrudes further into the thermal insulation space 103 than the second area 144 does.

[0108] Further, the first pipe section 21 may include a first portion 211 disposed around the first area 143 and a second portion 212 disposed around the second area 144. The first portion 211 and the second portion 212 may be flush along the direction z. In other words, a part (namely, the first pipe section 21) of the anti-condensation pipe 2 that extends into the thermal insulation space 103 is basically folded only along the direction x and the direction y to be disposed around the convex hull 15, and is maintained at a same height along the direction z. This helps reduce arrangement complexity of the anti-condensation pipe 2, and improves assembly efficiency.

[0109] In a variable example, referring to FIG. 13, there is also a non-zero height difference between the first portion 211 and the second portion 212, and the height difference between the first portion 211 and the second portion 212 matches the height difference between the first area 143 and the second area 144. In other words, during laying, corresponding step setting is also performed on the first pipe section 21 in cooperation with the shape of the outer contour of the convex hull 15. For example, a distance between the first portion 211 and the first area 143 may be approximately equal to a distance between the second portion 212 and the second area 144. Therefore, the first pipe section 21 is disposed attaching to an outer contour of the mounting portion 142, to further optimize an anti-condensation effect in an area that is at the top of the refrigeration appliance 1 and that corresponds to the mounting portion 142.

[0110] In a specific implementation, referring to FIG. 2 to FIG. 9, the projection of the first pipe section 21 along the height direction (for example, the direction z) of the refrigeration appliance 1 bypasses the flipping beam 14, and extends, on a rear side of the flipping beam 14, from one side of the flipping beam 14 to the other side of the flipping beam 14. Therefore, the condensation problem in an area that is on the top surface 102a of the outer housing 102 and that directly faces the flipping beam 14 is specifically resolved.

[0111] In a specific implementation, the anti-condensation pipe 2 may be a metal pipe, and the anti-condensation pipe 2 is connected to the compressor compartment and is in communication with a refrigeration cycle. Therefore, the heat generated during use of the refrigeration appliance 1 is used to prevent condensation on an outer surface of the refrigeration appliance 1.

[0112] In a specific implementation, in a normal condition, after the first door 11 is opened, the flipping beam 14 automatically rotates to the first position without interfering with the second door 12. However, the user may perform a misoperation to rotate the flipping beam 14 to the second position. In this specific implementation, even if the flipping beam 14 is at the second position, the protruding member 192 may enter the guide groove 191 to close the first door 11.

[0113] Specifically, the protruding member 192 may move relative to the first door 11 along a direction of a pivot axis of the first door 11. For example, the protruding member 192 may move relative to the flipping beam 14, an end portion of the flipping beam 14 may be provided with a cut-out 194 (as shown in FIG. 3) for mounting the protruding member 192, and the protruding member 192 is guided in the cut-out 194 in a manner of being vertically displaced. A sleeve is disposed on an inner side of the protruding member 192. The sleeve is sleeved on a pin 195 located in the flipping beam 14. The first guide member 19 may further include a coil spring that is located on the pin 195 and that is configured to support the protruding member 192. When no external force is applied, the coil spring may push the protruding member 192 upward.

[0114] Further, when the flipping beam 14 at the second position is close to the body 10, a guide slope of the protruding member 192 is slightly lower than a frontmost side on a tail end surface of a front surface (namely, a surface on which the entry 191a is located, which is flush with the butting surface 14a, as shown in FIG. 7) of the guide base 141 along a longitudinal direction on a side close to the body 10. Therefore, the protruding member 192 and the guide base 141 overlap along the longitudinal direction. If the first door 11 continues to be pushed, the tail end surface of the protruding member 192 is press-connected to the front surface of the guide base 141 to compress a rotating spring, and the protruding member 192 supported by the rotating spring moves downward until the protruding member 192 passes over the front surface of the guide base 141 and enters the guide groove 191. After a state of being press-connected to the front surface of the guide base 141 is released, the protruding member 192 moves toward a bottom wall of the guide groove 191 under support of the rotating spring. The protruding member 192 and the front surface of the guide base 141 overlap along a direction perpendicular to the butting surface 14a, to prevent the protruding member 192 from passing over the front surface of the guide base 141 and exiting the guide groove 191.

[0115] In this process, that is, when the flipping beam 14 is at the second position and the first door 11 is closed, the protruding member 192 does not rotate relative to the first door 11, but only performs linear movement relative to the first door 11. Therefore, when the flipping beam 14 is at the second position and the first door 11 is closed, an angle between the flipping beam 14 and the first door 11 remains unchanged, and the flipping beam 14 is horizontally pushed into the body 10.

A person skilled in the art can make various changes and modifications without departing from the spirit and the scope of the present invention.

Embodiment Construction

[0050]A guide mechanism needs to be fixed at a top of a refrigerator by using a fixing member. The fixing member passes through a top wall of a liner of the refrigerator and extends into a thermal insulation layer. This may affect thermal insulation performance of the thermal insulation layer. In addition, in some refrigerators, to improve aesthetics of a storage compartment, the top wall of the liner protrudes upward to form a mounting portion. The guide mechanism is mounted on the mounting portion, so that the top wall of the storage compartment is flat when viewed from the front. However, that causes a thinner thermal insulation layer and poorer thermal insulation performance. Practices show that for either of the foregoing two situations, heat generated by a conventional anti-condensation pipe disposed on a front side of the top cannot increase a temperature of an area at the top of the refrigerator above a dew point temperature, causing a condensation phenomenon still to occur ...
