Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] During refrigerator use, the food stored in the storage compartment and the air contain moisture, causing frost to form when the air passes through the evaporator. When the frost reaches a certain thickness, it affects the smooth flow of air through the evaporator, thus impacting the cooling effect. Therefore, it is necessary to defrost the evaporator regularly.

[0003] In related technologies, a drainage structure is provided at the bottom of the evaporator to drain defrost water into the evaporation dish inside the compressor compartment, allowing the defrost water to evaporate. The drain pipe of the drainage structure is fixed to the refrigerator shell; however, the reliability of the drain pipe's fixation is poor, resulting in an unstable drain pipe position that easily adheres to the shell, causing condensation problems. Utility Model Content

[0004] This application provides a refrigerator that improves the reliability of drain pipe fixing and reduces the possibility of condensation on the refrigerator shell.

[0005] This application provides a refrigerator, which includes:

[0006] Two inner boxes are provided, the inner boxes being constructed to form a storage compartment with an opening at the front; the two inner boxes are arranged side by side along the height of the inner boxes; a first drain pipe for drainage is connected to the rear side of the bottom of the upper inner box.

[0007] The outer shell is connected to the outside of the inner box; the outer shell includes two side panels, which are arranged opposite to each other along the width direction of the inner box.

[0008] At least one fixed bracket is fixedly connected to one of the box side plates, the fixed bracket is configured to form a clamping cavity for clamping the first drain pipe, and the clamping cavity has an opening on the side opposite to the box side plate;

[0009] The first drain pipe is constructed to form at least one limiting structure, which cooperates with the fixed bracket to restrict the first drain pipe's degrees of freedom along its length and circumference.

[0010] There is a gap between the first drain pipe and the shell, and there is a gap between the first drain pipe and the inner liner.

[0011] The refrigerator in this embodiment of the application is provided with a fixed bracket, which is configured to form a clamping cavity to clamp the first drain pipe; and by constructing a limiting structure on the first drain pipe, which cooperates with the fixed bracket, the first drain pipe is restricted in its length and circumferential directions, thereby ensuring the relative position of the first drain pipe with respect to the fixed bracket; the fixed bracket is fixedly connected to the side plate of the cabinet, thereby restricting the position of the first drain pipe with respect to the side plate, so that the first drain pipe is stably and reliably fixed in the space between the liner and the cabinet.

[0012] There is a gap between the first drain pipe and the shell, and there is also a gap between the first drain pipe and the inner tank. This allows the first drain pipe to be covered by the insulation layer between the inner tank and the shell. This not only helps to ensure the thermal insulation performance of the first drain pipe and reduce the possibility of freezing or condensation, but also helps to improve the stability of the first drain pipe and reduce the possibility of displacement.

[0013] In some embodiments of this application, the limiting structure includes two first limiting ribs, which extend along the length direction of the first drain pipe and are spaced apart along the circumference of the first drain pipe.

[0014] The two first limiting ribs abut against the two sides of the opening of the fixed bracket to restrict the first drain pipe from rotating relative to the fixed bracket.

[0015] By setting two first limiting ribs on the first drain pipe, which abut against the two sides of the clamping cavity opening of the fixed bracket, the degree of freedom of the first drain pipe relative to the fixed bracket in the circumferential direction is restricted, preventing the first drain pipe from rotating relative to the fixed bracket and improving the stability of the first drain pipe relative to the fixed bracket.

[0016] In some embodiments of this application, the fixing bracket includes a clamping portion, the clamping portion comprising:

[0017] An arc-shaped cylindrical portion, wherein the arc-shaped cylindrical portion is configured to form the clamping cavity with an opening on one side;

[0018] Two limiting arms are respectively connected to both sides of the opening of the arc-shaped cylindrical part, and the two limiting arms are inclined away from each other; the two limiting arms abut against the two first limiting ribs respectively.

[0019] The fixed bracket of this application embodiment forms a clamping cavity by setting an arc-shaped cylindrical part, and limits the degree of freedom of the first drain pipe along its circumference by setting limiting arms on both sides of the opening of the arc-shaped cylindrical part and abutting against the first limiting rib; and by setting two limiting arms, the structural strength of the fixed bracket can also be improved.

[0020] In some embodiments of this application, the limiting structure further includes two second limiting ribs, which are spaced apart along the length direction of the first drain pipe;

[0021] The portion of the first drain pipe located between the two second limiting ribs is clamped in the clamping cavity, and the two second limiting ribs respectively abut against the two ends of the fixed bracket.

[0022] By forming two second limiting ribs on the first drain pipe, the two ends of the fixed bracket abut against the two second limiting ribs respectively, thereby restricting the position of the first drain pipe along its length. The two second limiting ribs also provide positioning for the cooperation between the first drain pipe and the fixed bracket, improving assembly efficiency.

[0023] In some embodiments of this application, the rear end of the box side panel forms a mounting portion, and the mounting portion is configured to form a plug-in interface with a rear opening;

[0024] The enclosure also includes a back panel, which is inserted into the insertion interface on both sides along the width direction;

[0025] A fixing groove is formed between the mounting part and the side plate of the box, and the fixing bracket is fixed in the fixing groove.

[0026] In this embodiment, a mounting portion is formed at the rear end of the side panel of the box, which is fixedly connected to the back panel of the box; at the same time, a fixing groove is formed between the mounting portion and the side panel of the box, which is fixedly connected to the fixing bracket; no additional fixing structure is required, which helps to simplify the fixing structure of the fixing bracket.

[0027] In some embodiments of this application, the mounting part includes:

[0028] The first fold wall is formed by bending the rear ends of the two box side panels toward each other.

[0029] The second fold wall extends forward from the end of the first fold wall to form the second fold wall; the second fold wall and the box side panel are spaced apart along the width direction, and the second fold wall, the first fold wall and the box side panel together form the fixing groove; the second fold wall forms a limiting wall facing the first fold wall;

[0030] The fixing bracket is inserted into the fixing groove and abuts against the limiting wall to restrict the position of the fixing bracket along the depth direction of the box liner.

[0031] The installation part of this application embodiment forms a fixing groove by setting a first folding wall and a second folding wall together with the side plate of the box; and by forming a limiting wall in the second folding wall, which cooperates with the fixing bracket to limit the position of the fixing bracket along the depth direction of the box liner, the reliability of the connection between the fixing bracket and the fixing groove is further improved, thereby helping to improve the stability of the position of the first drain pipe.

[0032] In some embodiments of this application, the fixing bracket includes a fixing part, the fixing part comprising:

[0033] A connecting arm, one end of which is connected to the clamping part of the fixed bracket that forms the clamping cavity, so that there is a gap between the clamping part and the box side plate;

[0034] At least one fixed arm, the fixed arm comprising:

[0035] An arm body, one end of which is connected to the other end of the connecting arm; the arm body is bent relative to the connecting arm, and the side of the arm body facing away from the connecting arm abuts against the box side panel;

[0036] A first protrusion is disposed at the other end of the arm body, and the first protrusion is located on the side of the arm body facing the connecting arm; the first protrusion abuts against the limiting wall;

[0037] The second protrusion is connected to the side of the arm body facing the fixed arm, and the second protrusion is spaced apart from the first protrusion and the connecting arm; the second protrusion abuts against the second folded wall.

[0038] The fixing part in this embodiment of the application is provided with a connecting arm, so that there is a gap between the clamping part and the side plate of the box, thereby creating a gap between the first drain pipe and the side plate of the box; by providing a fixing arm that engages with the fixing groove, by providing a first protrusion that abuts against the limiting wall, and by providing a second protrusion that engages with the second folding wall, the reliability and stability of the connection between the fixing arm and the fixing groove are improved.

[0039] In some embodiments of this application, the fixing part is provided with two fixing arms, and the two fixing arms are symmetrically arranged about the connecting arm.

[0040] By setting two fixed arms, the symmetry of the fixing part can be increased, and the structural strength can be improved; moreover, it can play a foolproof role, so that the fixing bracket can still be installed even if it is rotated 180°, which helps to improve assembly efficiency.

[0041] In some embodiments of this application, the refrigerator further includes a water outlet, which is fixed to the outside of the refrigerator liner; the water outlet is configured to form a connecting pipe portion, which is connected to the first drain pipe.

[0042] The connecting pipe is inclined downward toward one of the box side plates, and the fixing bracket is fixed to the box side plate.

[0043] In this embodiment, the water outlet is connected to the first drain pipe by a connecting pipe portion that is inclined toward the side plate of the tank. This allows at least a portion of the first drain pipe to be located in the area with a thicker insulation layer between the upper and lower tank liner, making the extension of the first drain pipe smoother and improving the smoothness of drainage.

[0044] In some embodiments of this application, the first drain pipe includes:

[0045] A straight tube extends along the height direction of the housing and is disposed near the connection between the side panel and the back panel of the housing; a portion of the straight tube is clamped in the clamping cavity;

[0046] The first bend has its top end connected to the inner box, and its bottom end extends to the side plate of the box and is connected to the top end of the straight tube.

[0047] The second bend has its top end connected to the bottom end of the straight tube, and its bottom end extends to the evaporation dish of the refrigerator.

[0048] In this embodiment, by bending the first drain pipe so that the first bent portion of the first drain pipe extends toward the side panel of the box, and the first drain pipe is located between the upper box liner and the lower box liner, the insulation layer is thicker, which helps to reduce the possibility of the first drain pipe freezing and blocking.

[0049] The first drain pipe has a straight section extending along the height of the chamber liner. This straight section is connected to a fixed bracket to secure the first drain pipe. The straight section is located at the junction of the side panel and the back panel of the chamber, and has a relatively thick insulation layer, which helps to reduce the possibility of the first drain pipe freezing and becoming blocked. The first drain pipe extends to the evaporating dish through a second bend to allow water to flow into the evaporating dish. Attached Figure Description

Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0072] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0073] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0074] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] First, it should be noted that, in the embodiments of this application, as... Figure 1 As shown, the width direction of the box body 100 or the box liner 120 corresponds to Figure 1 In the X-axis direction, the height direction of the housing 100 or the inner liner 120 corresponds to Figure 1 In the Z-axis direction, the depth direction of the housing 100 or the inner liner 120 corresponds to... Figure 1 In the Y-axis direction.

[0076] Combination Figure 1 This application provides a refrigerator, which includes a cabinet 100, which can be configured to form a storage compartment 101 for storing items.

[0077] The storage compartment 101 can be provided in multiple ways to expand the storage space. Depending on the storage temperature of the storage compartment 101, the storage compartment 101 can include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C to store items in refrigeration mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C to store items in freezing mode.

[0078] In some possible implementations, at least one of the storage chambers 101 may also be configured as a vacuum chamber or a variable temperature chamber, etc.

[0079] For example, two storage compartments 101 can be provided, which can be stacked vertically or arranged side by side horizontally. One of them can be a refrigerator compartment and the other can be a freezer compartment.

[0080] The refrigerator in this embodiment may also include a door, which is connected to the cabinet 100 to open or close the storage compartment 101.

[0081] For example, the door and the cabinet 100 are hinged together, so that the door can rotate relative to the cabinet 100, thereby opening or closing the storage room 101.

[0082] For example, the drawer is provided with a door at its outer end, and the door and the drawer are simultaneously pulled out relative to the box 100 to open or close the storage compartment 101.

[0083] A storage room 101 may be equipped with one door, for example, a cold storage room may be equipped with one door; a storage room 101 may also be equipped with multiple doors, for example, a cold storage room may be equipped with two doors that open in opposite directions.

[0084] In some embodiments, combined with Figure 1 and Figure 2 The refrigerator body 100 may include a refrigerator liner 120 and a refrigerator shell 110. The refrigerator liner 120 may be configured with a storage compartment 101. The refrigerator shell 110 may be attached to the outside of the refrigerator liner 120 to form the appearance of the refrigerator.

[0085] When there are multiple storage compartments 101, there can be multiple inner boxes 120, with each inner box 120 constituting one storage compartment 101.

[0086] For example, in this embodiment of the application, two cabinet liners 120 are provided, and the two cabinet liners 120 are arranged side by side along the height direction of the cabinet body 100. The upper cabinet liner 120 can be a refrigerator cabinet liner, which defines a refrigerator compartment; the lower cabinet liner 120 can be a freezer cabinet liner, which defines a freezer compartment.

[0087] The cabinet 100 may also include an insulation layer, which can be disposed between the inner cabinet 120 and the outer shell 110. The insulation layer can insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigerator, thus helping to ensure the refrigerator's cooling effect. The insulation layer can be formed by foaming, such as polyurethane foam.

[0088] In some embodiments, combined with Figure 1 and Figure 2 The refrigerator shell 110 may include a top panel 111, two side panels 112, and a back panel 113. The two side panels 112 are spaced apart along the width of the refrigerator, and the top panel 111 is fixed to the top of the two side panels 112. The two side panels 112 and the back panel 113 can be integrally formed into a U-shaped shell, which helps to improve the structural strength of the refrigerator shell 110 and reduce the assembly process. The back panel 113 is fixed to the back of the top panel 111 and the two side panels 112.

[0089] The box shell 110 may also include a box bottom plate 114, which is opposite to the box top plate 111 along the height direction and is spaced apart. The box bottom plate 114 is fixed to the bottom of the two box side plates 112 and the box back plate 113.

[0090] Continue to refer to Figure 1 In some embodiments, the housing 100 may also be configured to form a compressor compartment 102, in which the compressor, condenser, and other components of the refrigeration system are installed. The compressor compartment 102 is located at the rear side of the bottom of the bottom housing 120.

[0091] Exemplarily, the cabinet 100 also includes a press cover 130 and a bottom plate portion 140, the press cover 130 being fixed to the bottom of the cabinet liner 120. The press cover 130 includes a bottom wall portion 131, a top wall portion 132, and a front wall portion 133, the bottom wall portion 131 being located on the bottom surface of the cabinet liner 120. The rear end of the bottom wall portion 131 bends upward to form the front wall portion 133; the top end of the front wall portion 133 bends backward to form the top wall portion 132. The bottom plate portion 140 is located behind the bottom wall portion 131, and the bottom plate portion 140 and the top wall portion 132 are opposite to and spaced apart along the height direction of the refrigerator.

[0092] The housing 100 also includes two side wall portions 150, which are fixed to both sides of the top wall portion 132 along the width direction, so that the press cover 130 and the bottom plate portion 140 enclose to form a rearward-opening press chamber 102.

[0093] The housing 100 may also include a cover plate, which is detachably connected to the housing 110 and covers the rear opening of the press chamber 102. The components inside the press chamber 102 can be maintained by removing the cover plate.

[0094] The bottom wall portion 131 and the bottom plate portion 140 form the bottom plate 114 of the cabinet 110. The cover plate and the back plate 113 together form the rear appearance of the refrigerator.

[0095] An insulation layer may be provided between the bottom wall 131 and the bottom surface of the inner liner 120; an insulation layer may be provided between the back panel 113 and the back of the inner liner 120; and an insulation layer may be provided between the side panel 112 and the side of the inner liner 120.

[0096] Reference Figure 3 and Figure 4 In some embodiments of this application, an evaporator 200 is provided inside the upper chamber 120 to cool at least the space inside the upper chamber 120. The evaporator 200 inside the upper chamber 120 may cool only the space inside the upper chamber 120, or it may cool the spaces inside both chambers 120 simultaneously.

[0097] In this embodiment of the application, the refrigerator is equipped with two evaporators 200, one of which is installed in the upper liner 120 and the other in the lower liner 120.

[0098] When the evaporator 200 defrosts, defrost water is generated. Therefore, the tank liner 120 is usually equipped with a drainage structure to drain the defrost water from the evaporator 200.

[0099] An evaporating dish 160 is typically installed inside the compressor chamber 102. A drainage structure discharges defrost water into the evaporating dish 160 to evaporate the defrost water. Therefore, the drainage structure needs to extend from the inner chamber 120 to the compressor chamber 102. This drainage structure may include a drain pipe for convenient pipework layout and extension.

[0100] Combination Figure 5 In some embodiments of this application, a first drain pipe 300 for draining water is connected to the rear side of the bottom of the upper liner 120. The first drain pipe 300 can be used to drain defrost water from the evaporator 200 of the air-cooled refrigerator, or to drain condensate from the refrigeration refrigerator. The first drain pipe 300 extends into the compressor compartment 102 and is opposite to the evaporation dish 160 to drain water into the evaporation dish 160.

[0101] Continue to refer to Figure 5 The bottom rear side of the lower chamber 120 is connected to a second drain pipe 600. The second drain pipe 600 extends into the compressor chamber 102 and is opposite to the evaporating dish 160 to drain water into the evaporating dish 160.

[0102] Along the height direction of the housing 100, the lower chamber 120 is closer to the compressor chamber 102. The second drain pipe 600 can extend along the height direction of the housing 100, which can shorten the length of the second drain pipe 600, so that the defrosting water of the evaporator 200 in the lower chamber 120 can be quickly discharged to the evaporating dish 160.

[0103] Because the first drain pipe 300 needs to cross the lower chamber 120 to enter the compressor chamber 102, the first drain pipe 300 is relatively long, requiring a fixing structure for the first drain pipe 300. (Continue referring to...) Figure 5 The refrigerator in this embodiment may also include at least one fixed bracket 400, which is used to fix the first drain pipe 300. The fixed bracket 400 is also fixedly connected to the shell 110 so that the relative positions of the first drain pipe 300 and the shell 110 are fixed.

[0104] Reference Figure 7 and Figure 8 In some embodiments of this application, the fixed bracket 400 is fixedly connected to the side panel 112 of the box, which not only improves the convenience of assembly, but also allows the first drain pipe 300 to be close to the triangular area between the side panel 112 and the back panel 113 of the box, with sufficient arrangement space and little impact on the insulation layer.

[0105] The fixed bracket 400 is snapped into the side panel 112 of the box, which is a simple connection method and easy to assemble. Alternatively, the fixed bracket 400 is glued to the side panel 112 of the box, which provides a stable connection.

[0106] One fixed bracket 400 can be provided, which has a simple structure and is easy to assemble.

[0107] Two fixed supports 400 can be provided, and the two fixed supports 400 can be arranged at intervals along the height direction of the box 100 to improve the reliability of fixing the first drain pipe 300.

[0108] Of course, three, four or more fixed brackets 400 can be set, and multiple fixed brackets 400 are arranged at intervals along the extension direction of the first drain pipe 300 to further improve the stability of the installation of the first drain pipe 300.

[0109] To facilitate the installation of the 400 fixed bracket, combined with Figure 6A portion of the first drain pipe 300 extends along the height direction of the box 100, and the fixed bracket 400 is connected to and fixed to the portion of the first drain pipe 300 extending along the height direction.

[0110] Reference Figure 8 and Figure 9 The fixed bracket 400 is configured to form a clamping cavity 401 for clamping the first drain pipe 300. The clamping cavity 401 is open at both ends along the length direction of the first drain pipe 300, which facilitates clamping the first drain pipe 300. Furthermore, the clamping cavity 401 is open on the side opposite to the side plate 112 of the box, which facilitates clamping the first drain pipe 300 in the clamping cavity 401 from the opening.

[0111] To improve the stability of the clamping cavity 401 in clamping the first drain pipe 300, the inner wall of the clamping cavity 401 extends in an arc shape to increase the contact area between the clamping cavity 401 and the first drain pipe 300, which is beneficial to improving the clamping stability. However, this is not a limitation on the shape of the clamping cavity 401; for example, the inner wall of the clamping cavity 401 can be polygonal.

[0112] The opening on the side of the clamping cavity 401 is smaller than the outer diameter of the first drain pipe 300, so that the first drain pipe 300 can both open the fixed bracket 400 and be clamped in the clamping cavity 401, and the fixed bracket 400 can clamp the first drain pipe 300 without falling off.

[0113] In some embodiments of this application, the fixing bracket 400 includes a clamping portion 410, which is configured to form a clamping cavity 401.

[0114] The fixed bracket 400 also includes a fixing part 420, which is connected to the clamping part 410 and is located on the side of the clamping cavity 401 opposite to the opening. The fixing part 420 is fixedly connected to the side plate 112 of the box so that the fixed bracket 400 is installed on the side plate 112 of the box.

[0115] The fixing part 420 is snapped into the side panel 112 of the box, making the assembly method simple.

[0116] Reference Figure 10 In some embodiments of this application, the first drain pipe 300 is configured to form at least one limiting structure 310, which cooperates with the fixed bracket 400 to restrict the degrees of freedom of the first drain pipe 300 along its length and circumferential directions.

[0117] One limiting structure 310 may be provided, which cooperates with one of the fixed brackets 400 to limit the position of the first drain pipe 300.

[0118] When multiple fixed supports 400 are provided in the refrigerator, multiple limiting structures 310 are provided. Each limiting structure 310 cooperates with one of the fixed supports 400 to limit the position of the first drain pipe 300.

[0119] In this embodiment, the first drain pipe 300 is limited by the fixed bracket 400, creating a gap between the first drain pipe 300 and the outer shell 110, and also a gap between the first drain pipe 300 and the inner shell 120. This allows the insulation layer between the inner shell 120 and the outer shell 110 to enter the space between the first drain pipe 300 and the inner shell 120, and also between the first drain pipe 300 and the outer shell 110. This avoids both freezing and condensation problems caused by contact between the first drain pipe 300 and the inner shell 120.

[0120] Therefore, the refrigerator in this embodiment of the application is provided with a fixed bracket 400, which is configured to form a clamping cavity 401 to clamp the first drain pipe 300; and by constructing a limiting structure 310 on the first drain pipe 300, which cooperates with the fixed bracket 400, the freedom of the first drain pipe 300 along its length and circumference is restricted, thereby ensuring the relative position of the first drain pipe 300 with respect to the fixed bracket 400; the fixed bracket 400 is fixedly connected to the side plate 112 of the cabinet 110, thereby restricting the position of the first drain pipe 300 with respect to the side plate 112, so that the first drain pipe 300 is stably and reliably fixed in the space between the liner 120 and the cabinet 110.

[0121] There is a gap between the first drain pipe 300 and the shell 110, and there is also a gap between the first drain pipe 300 and the inner liner 120. This allows the first drain pipe 300 to be covered by the insulation layer between the inner liner 120 and the shell 110. This not only helps to ensure the heat insulation performance of the first drain pipe 300 and reduce the possibility of freezing or condensation, but also helps to improve the stability of the first drain pipe 300 and reduce the possibility of displacement.

[0122] In this embodiment, the first drain pipe 300 is guided to be close to the side panel 112 of the box, so that part of the first drain pipe 300 can be arranged in the triangular area between the side panel 112 and the back panel 113 of the box. This not only provides sufficient space for arrangement, but also reduces the impact of the first drain pipe 300 on the thickness of the insulation layer.

[0123] Combination Figure 8 In some embodiments of this application, the limiting structure 310 includes two first limiting ribs 311, which extend along the length direction of the first drain pipe 300 and are spaced apart along the circumference of the first drain pipe 300.

[0124] When the limiting structure 310 is provided on the portion of the first drain pipe 300 that extends along the height direction, the two first limiting ribs 311 extend along the height direction of the box body 100.

[0125] The two first limiting ribs 311 abut against the two sides of the opening of the fixed bracket 400 to restrict the first drain pipe 300 from rotating relative to the fixed bracket 400.

[0126] By setting two first limiting ribs 311 on the first drain pipe 300, which abut against the two sides of the opening of the clamping cavity 401 of the fixed bracket 400, the degree of freedom of the first drain pipe 300 relative to the fixed bracket 400 in the circumferential direction is restricted, the first drain pipe 300 is prevented from rotating relative to the fixed bracket 400, and the stability of the first drain pipe 300 relative to the fixed bracket 400 is improved.

[0127] Continue to refer to Figure 9 In some embodiments of this application, the clamping portion 410 of the fixing bracket 400 includes an arc-shaped cylindrical portion 411, which is configured to form a clamping cavity 401 with an opening on one side. The arc-shaped cylindrical portion 411 extends along the length direction of the first drain pipe 300, and the clamping cavity 401 is a through hole extending along the length direction of the first drain pipe 300. The clamping cavity 401 has a side opening so that the first drain pipe 300 can be inserted into the clamping cavity 401 from the side opening.

[0128] The arc-shaped cylindrical part 411 has an angle greater than 180°, which allows the first drain pipe 300 to be stably clamped in the clamping cavity 401.

[0129] The clamping portion 410 of the fixed bracket 400 may further include two limiting arms 412, which are respectively connected to both sides of the opening of the arc-shaped cylindrical portion 411, and the two limiting arms 412 are inclined away from each other. The distance between the two limiting arms 412 widens from the center of the arc-shaped cylindrical portion 411 outwards, making the clamping portion 410 approximately trumpet-shaped. The two limiting arms 412 respectively abut against the two first limiting ribs 311.

[0130] The included angle between the two limiting arms 412 can be between 90° and 120°, which can both allow the first drain pipe 300 to be inserted into the clamping cavity 401 through the opening on the side of the clamping cavity 401 and reduce the possibility of the first drain pipe 300 detaching from the opening.

[0131] The fixed bracket 400 of this application embodiment forms a clamping cavity 401 by setting an arc-shaped cylindrical portion 411. Limiting arms 412 are provided on both sides of the opening of the arc-shaped cylindrical portion 411 to abut against the first limiting rib 311, thereby restricting the degree of freedom of the first drain pipe 300 along its circumference. Furthermore, by setting two limiting arms 412, the structural strength of the fixed bracket 400 can also be improved.

[0132] Continue to refer to Figure 8 and Figure 10 The limiting structure 310 also includes two second limiting ribs 312, which are spaced apart along the length of the first drain pipe 300.

[0133] For example, the second limiting rib 312 is annular and extends circumferentially along the first drain pipe 300. Of course, this is not a limitation on the shape of the second limiting rib 312; the second limiting rib 312 can also be arc-shaped.

[0134] The portion of the first drain pipe 300 located between the two second limiting ribs 312 is clamped in the clamping cavity 401, and the two second limiting ribs 312 respectively abut against the two ends of the fixed bracket 400.

[0135] By forming two second limiting ribs 312 on the first drain pipe 300, the two ends of the fixed bracket 400 abut against the two second limiting ribs 312 respectively, thereby limiting the position of the first drain pipe 300 along its length. The two second limiting ribs 312 can also provide positioning for the cooperation between the first drain pipe 300 and the fixed bracket 400, improving assembly efficiency.

[0136] Continue to refer to Figure 8 The rear end of the side panel 112 forms a mounting portion 170, which is configured to form a rear-opening insertion interface 171. The back panel 113 of the housing 110 is inserted into the insertion interface 171 along both sides in the width direction. The back panel 113 is bent forward along both sides in the width direction to form insertion edges, which are inserted into the insertion interface 171 to achieve a fixed connection between the back panel 113 and the side panel 112.

[0137] A fixing groove 172 is formed between the mounting part 170 and the side plate 112 of the box, and the fixing bracket 400 is fixed in the fixing groove 172.

[0138] The fixing part 420 of the fixed bracket 400 is inserted into the fixing groove 172, and the installation method is simple and reliable.

[0139] In this embodiment, a mounting portion 170 is formed at the rear end of the side panel 112 of the box, which is fixedly connected to the back panel 113 of the box; at the same time, a fixing groove 172 is formed between the mounting portion 170 and the side panel 112 of the box, which is fixedly connected to the fixing bracket 400; no additional fixing structure is required, which helps to simplify the fixing structure of the fixing bracket 400.

[0140] Reference Figure 8 In some embodiments of this application, the mounting portion 170 includes a first fold wall 173, wherein the rear ends of two box side panels 112 are bent toward each other to form the first fold wall 173.

[0141] The mounting section 170 also includes a second fold wall 174, the end of the first fold wall 173 being bent forward to form the second fold wall 174. The second fold wall 174 is spaced from the side panel 112 in the width direction, and the second fold wall 174, the first fold wall 173, and the side panel 112 together form a fixing groove 172.

[0142] The mounting section 170 also includes a third fold wall 175, and the second fold wall 174 is away from the end of the first fold wall 173, and extends backward after bending away from the side panel 112. The third fold wall 175 and the second fold wall 174 enclose each other to form an insertion interface 171.

[0143] Continue to refer to Figure 8 The second fold wall 174 forms a limiting wall 1741 facing the first fold wall 173, and the limiting wall 1741 and the first fold wall 173 are opposite each other along the depth direction of the box 100.

[0144] This can be understood as follows: the second folding wall 174 includes a first part and a second part; along the width direction of the box body 100, the first part has a first gap with the box side panel 112, and the second part has a second gap with the box side panel 112, the second gap being larger than the first gap. The second part and the first part are connected by a limiting wall 1741, the end of the first part facing away from the second part is connected to the third folding wall 175, and the end of the second part facing away from the first part is connected to the first folding wall 173.

[0145] The fixed bracket 400 is inserted into the fixed groove 172 and abuts against the limiting wall 1741 to limit the position of the fixed bracket 400 along the depth direction of the box liner 120.

[0146] The fixing part 420 of the fixing bracket 400 is inserted into the fixing groove 172, engages with the fixing groove 172, and abuts against the limiting wall 1741 to limit the position of the fixing bracket 400 along the depth direction of the box liner 120, thereby further improving the reliability of the connection between the fixing bracket 400 and the fixing groove 172.

[0147] The mounting part 170 of this application embodiment forms a fixing groove 172 together with the side plate 112 by setting a first folding wall 173 and a second folding wall 174; and by forming a limiting wall 1741 in the second folding wall 174, which cooperates with the fixing bracket 400 to limit the position of the fixing bracket 400 along the depth direction of the box liner 120, the reliability of the connection between the fixing bracket 400 and the fixing groove 172 is further improved, thereby helping to improve the stability of the position of the first drain pipe 300.

[0148] Continue to refer to Figure 9 The fixing part 420 of the fixing bracket 400 includes a connecting arm 421, one end of which is connected to the clamping part 410 so that there is a gap between the clamping part 410 and the box side plate 112, thereby creating a gap between the first drain pipe 300 and the box side plate 112.

[0149] The fixing part 420 may further include at least one fixing arm 422, which is fixedly connected to the side panel 112 of the box. The fixing arm 422 engages with the fixing groove 172, so that the fixing bracket 400 is fixed to the side panel 112 of the box.

[0150] The fixed arm 422 includes an arm body 4221, one end of which is connected to the other end of the connecting arm 421; the arm body 4221 is bent relative to the connecting arm 421, and the side of the arm body 4221 facing away from the connecting arm 421 abuts against the side plate 112 of the box.

[0151] The connecting arm 421 can extend in a direction perpendicular to the side panel 112 of the box, and the arm body 4221 can extend in a direction parallel to the side panel 112 of the box.

[0152] The fixed arm 422 may also include a first protrusion 4222, which is disposed at the other end of the arm body 4221 and is located on the side of the arm body 4221 facing the connecting arm 421; the first protrusion 4222 abuts against the limiting wall 1741.

[0153] The fixed arm 422 may further include a second protrusion 4223, which is connected to the side of the arm body 4221 facing the connecting arm 421, and is spaced apart from the first protrusion 4222 and the connecting arm 421 respectively; the second protrusion 4223 abuts against the second folded wall 174. The second protrusion 4223 abuts against the first part of the second folded wall 174.

[0154] The second protrusion 4223 and the first protrusion 4222 are both located on the same side of the arm body 4221 and on the side away from the box side plate 112; the second protrusion 4223 is located between the first protrusion 4222 and the connecting arm 421.

[0155] Therefore, in this embodiment of the application, the fixing part 420 is provided with a connecting arm 421, which creates a gap between the clamping part 410 and the box side plate 112, thereby creating a gap between the first drain pipe 300 and the box side plate 112; the fixing arm 422 is provided to engage with the fixing groove 172, the first protrusion 4222 abuts against the limiting wall 1741, and the second protrusion 4223 engages with the second folding wall 174, thereby improving the reliability and stability of the connection between the fixing arm 422 and the fixing groove 172.

[0156] Continue to refer to Figure 9 The fixing part 420 is provided with two fixing arms 422, which are arranged symmetrically about the connecting arm 421.

[0157] By setting two fixing arms 422, the symmetry of the fixing part 420 can be increased, and the structural strength can be improved; moreover, it can play a foolproof role, so that the fixing bracket 400 can still be installed even if it is rotated 180°, which helps to improve assembly efficiency.

[0158] Continue to refer to Figure 5 and Figure 10 In some embodiments of this application, the first drain pipe 300 includes: a straight pipe portion 320 extending along the height direction of the housing 110 and disposed near the connection between the side panel 112 and the back panel 113; a portion of the straight pipe portion 320 is clamped in the clamping cavity 401.

[0159] Reference Figure 11 and Figure 12 The straight pipe section 320 is located at the connection between the side panel 112 and the back panel 113 of the box, which provides sufficient space for the straight pipe section 320. This ensures that there is enough space between the straight pipe section 320 and the box liner 120 to arrange the insulation layer, thereby ensuring that there is sufficient distance between the first drain pipe 300 and the lower box liner 120, reducing the possibility of the first drain pipe 300 freezing and becoming blocked.

[0160] Furthermore, since the straight pipe section 320 is located at the connection between the side panel 112 and the back panel 113, the straight distance L1 between the straight pipe section 320 and the inner liner 120 is relatively large. Under the premise of ensuring that the first drain pipe 300 does not freeze and become blocked, the effective volume of the refrigerator can be increased by reducing the thickness of the insulation layer at this location.

[0161] The first drain pipe 300 may also include a first bend 330, the top end of which is connected to the liner 120, and the bottom end of which extends to the side plate 112 and is connected to the top end of the straight pipe 320.

[0162] Combination Figure 13The first curved section 330 is located in the area between the upper liner 120 and the lower liner 120. The insulation layer in this area is thicker, which can reduce the possibility of the first drain pipe 300 running out of the space.

[0163] Reference Figure 10 The first drain pipe 300 may further include a second bend 340, the top end of which is connected to the bottom end of the straight pipe 320, and the bottom end of which extends to the evaporation dish 160 of the refrigerator. The second bend 340 passes through the top wall 132 of the compressor cover 130 and enters the compressor chamber 102.

[0164] Reference Figure 5 The first drain pipe 300 may also include a telescopic pipe section located inside the compressor chamber 102. The top end of the telescopic pipe section is connected to the bottom end of the second bend 340, and the bottom end of the telescopic pipe section is opposite to the evaporating dish 160.

[0165] In this embodiment, by bending the first drain pipe 300, the first bent portion 330 of the first drain pipe 300 extends toward the side panel 112 of the box, and the first drain pipe 300 is located between the upper box liner 120 and the lower box liner 120. The insulation layer is thicker, which helps to reduce the possibility of the first drain pipe 300 freezing and blocking.

[0166] The first drain pipe 300 is provided with a straight pipe section 320 extending along the height direction of the box liner 120. The straight pipe section 320 is connected to the fixed bracket 400 to fix the first drain pipe 300. The straight pipe section 320 is located at the connection between the box side plate 112 and the box back plate 113. The insulation layer is thick, which helps to reduce the possibility of freezing and blockage of the first drain pipe 300.

[0167] The first drain pipe 300 extends to the evaporating dish 160 through a second bend 340 to drain water into the evaporating dish 160.

[0168] Reference Figure 13 and Figure 14 The refrigerator in this embodiment of the application also includes a water outlet 500, which is fixed to the outside of the cabinet liner 120; the water outlet 500 is configured to form a connecting pipe portion 520, which is connected to the first drain pipe 300.

[0169] The connecting pipe 520 is inclined downward toward one of the box side plates 112, and the fixing bracket 400 is fixed to the box side plate 112.

[0170] The water outlet 500 of this embodiment is connected to the first drain pipe 300 by a connecting pipe portion 520 inclined toward the side plate 112 of the tank, so that at least a part of the first drain pipe 300 can be located in the area with a thicker insulation layer between the upper tank liner 120 and the lower tank liner 120, so that the extension of the first drain pipe 300 is smoother and the drainage is improved.

[0171] Reference Figure 13 The bottom rear side of the tank liner 120 forms a connecting part, which protrudes downwards and has a recessed inner side to facilitate the collection of defrosting water. The connecting part forms a water outlet.

[0172] Among them, reference Figure 14 The water outlet 500 includes a connecting seat 510, which is fixedly connected to the tank liner 120. The connecting seat 510 covers the outside of the connecting part, achieving a stable connection between the connecting seat 510 and the connecting part.

[0173] The connector 510 is constructed to form a collection groove, which facilitates the collection of defrosting water.

[0174] The bottom end of the connecting seat 510 is connected to the connecting tube 520, so that the gathering groove is connected to the connecting tube 520.

However, this is not limiting. In some single-system direct-cooling refrigerators with one evaporator 200, the above-described drain pipe structure and arrangement can also be applied.
