Description

TECHNICAL FIELD

[0001] The utility model relates to refrigeration equipment technical field, concretely relates to a freezer. BACKGROUND

[0002] As a widely used refrigeration equipment in family and commercial places, the rationality of the door body design of the double-door refrigerator has important influence on the use convenience and appearance beauty of the product. The double-door refrigerator on the market usually adopts middle plane end cover design, that is, the end cover between the two doors is a plane structure, and the two door bodies are fixed on the same box through the hinge at the back. However, this design has some obvious defects in actual use.

[0003] Firstly, due to the difference of hinge elasticity, the inconsistency of the weight of the two doors and the door body flatness error caused by the production process tolerance, the two doors are often difficult to realize perfect alignment after assembly. The combined action of these factors is easy to cause uneven gap between the two doors, affecting the overall appearance. Secondly, during the process of closing or opening the two doors at the same time, due to the uneven gap between the doors, the top surfaces of the two doors often cannot be kept on the same horizontal plane. This not only affects the appearance of the refrigerator, but also may affect the sealing performance of the door body to a certain extent, causing cold air leakage or external temperature affecting the refrigeration effect. In addition, the traditional plane end cover design has high requirements for the position and compression amount of the door body during production and assembly, and slight deviation may cause the problems of door gap and uneven top surface, increasing the production cost and difficulty.

[0004] In view of the above problems, the prior art has not provided an effective solution, and there is an urgent need for an end cover structure design which can ensure smooth opening and closing of the two doors while ensuring uniform door gap and flush door top surface. The existing double-door refrigerator has the problems of uneven door gap and uneven door top surface in the end cover structure design, and it is urgent to improve the appearance quality and use experience of the product by improving the supporting structure and limiting method of the end cover.

[0043] As Figures 1 to 12As shown, according to the embodiment of the utility model, propose a kind of freezer 100, the freezer 100 include box 10, door body and limiting component 40, wherein box 10 has storage room and is equipped with the opening being communicated with storage room, door body includes and is arranged in the first door body 20 and the second door body 30 of opening, one end of first door body 20 and one end of second door body 30 are respectively hinged with box 10, first door body 20 and second door body 30 are used to close or open opening, the side of first door body 20 facing second door body 30 has first end cap 21, the side of second door body 30 facing first door body 20 has second end cap 31, limiting component 40 is located between first end cap 21 and second end cap 31, when first door body 20 and second door body 30 close opening, first end cap 21 and second end cap 31 are arranged to be relatively fixed by limiting component 40, in opening and closing direction, when the relative force between first end cap 21 and second end cap 31 is greater than preset force, first end cap 21 and second end cap 31 can be separated from each other by limiting component 40.

[0044] The freezer 100 provided by the utility model, by setting limiting component 40 between first door body 20 and second door body 30, and connecting limiting component 40 to first end cap 21 and second end cap 31 respectively, thereby effectively solve the problem that top surface is not flush due to flatness error in double-door structure. Specifically, the design of limiting component 40 can provide accurate limiting between the door bodies of double-door freezer. First, in double-door design, the top surfaces of the two door bodies often appear uneven due to the deviation of hinges or other factors, resulting in obvious height difference when the door bodies are closed. Through the docking and mechanical limiting of limiting component 40, the top surfaces of the two door bodies can be flush, eliminating the height difference caused by hinge error or door body deformation. In summary, the setting of limiting component 40 ensures that the two door bodies can maintain consistent flush top surface when closed, and the effect of limiting component 40 enables the top surfaces of first door body 20 and second door body 30 to be accurately aligned, thereby avoiding the unevenness of door body top surface due to flatness error, significantly improving the appearance quality of freezer 100. In addition, the design of limiting component 40 avoids interference of the door body during opening and closing, ensuring the smoothness and stability of door body action, not only improving the appearance, but also effectively avoiding the problems of cold air leakage or poor sealing caused by insufficient door seal compression. In summary, the utility model optimizes the structural design of end cap and limiting component 40, successfully solves the problem of large flatness error of double-door freezer 100 door body, improves the flushness of door body top surface, enhances the assembly precision and sealing performance of door body, significantly improves the appearance and use experience of freezer 100, has high technical value and practical application prospect.

[0045] It is understandable that the first end cap 21 can be integrally formed with the first door body 20, or the first end cap 21 can be separately formed from the first door body 20. The second end cap 31 and the second door body 30 are configured in the same way as the first end cap 21 and the first door body 20.

[0046] It is understood that in some embodiments, when the first door 20 and the second door 30 close the opening, the side of the first door 20 that is opposite to the second door 30 can fit against the second door 30, that is, there is no gap between the first door 20 and the second door 30. This setting ensures the sealing performance and appearance consistency when the door is closed, and effectively improves the energy efficiency of the freezer 100.

[0047] Understandably, in some embodiments, the opposite sides of the first door 20 and the second door 30 are designed to have an appropriate gap 101, and the contact surface can be designed as a straight line or an arc shape. However, in a double-door freezer structure, the hinge point of the two doors may result in an uneven gap 101 between the doors when closed due to factors such as the weight of the doors themselves, differences in the elasticity of the hinges, or manufacturing tolerances. Therefore, the limiting component 40, by being disposed on the end caps on opposite sides of the two doors, provides a clear limiting position when the doors are closed, restricting the range of movement of the doors and ensuring that the doors have the same spatial distance when closed, thereby ensuring that the gap 101 between the two doors is uniform.

[0048] In some implementations, the opening is located at the top of the cabinet 10. The top-mounted opening of the freezer 100 allows the door to rotate upwards or outwards when opened. This top-opening design facilitates access to taller items and avoids taking up too much vertical space, making it suitable for locations with limited height but requiring ample storage space.

[0049] In other embodiments, the opening is located on one side of the box 10. The side opening design can effectively utilize vertical space, making it easy to store and retrieve items, while avoiding taking up too much horizontal space.

[0050] It should be understood that the "up and down" direction mentioned in the text refers to the vertical direction from the top to the bottom of the housing 10 (e.g., ...). Figure 1 The z-axis direction is the horizontal direction from the left to the right of the box 10 (e.g., the left and right directions are the same). Figure 1 (in the y-axis direction).

[0051] It is important to understand that the opening and closing direction refers to the direction in which the two doors open and close, that is, the direction in which the doors rotate around the hinge axis.

[0052] like Figures 3 to 7As shown, the opening is arranged at the top of the cabinet 10 and has a gap between the first door body 20 and the second door body 30. In the first embodiment, the limiting assembly 40 is directly arranged on the first end cover 21 and the second end cover 31. The limiting assembly 40 includes a first limiting piece 41 and a second limiting piece 42. The first limiting piece 41 is arranged on the first end cover 21, and the second limiting piece 42 is arranged on the second end cover 31 and fixed opposite to the first limiting piece 41. When the first limiting piece 41 and the second limiting piece 42 abut against each other, the top surfaces of the first door body 20 and the second door body 30 can be flush with each other. When the relative force in the opening and closing direction between the first end cover 21 and the second end cover 31 is greater than the preset force, the first limiting piece 41 and the second limiting piece 42 can be relatively separated.

[0053] In the embodiment, the relative arrangement of the first limiting piece 41 and the second limiting piece 42 is very critical. The design and relative position thereof ensure that the top surfaces of the two door bodies can be flush, and solve the problems of uneven gap 101 and unevenness caused by the flatness error of the door bodies. Specifically, the first limiting piece 41 is located on one side of the first end cover 21, and the second limiting piece 42 is located at the corresponding position of the second end cover 31. The symmetric arrangement of the two ensures that the limiting assembly 40 can accurately dock when the two door bodies are closed.

[0054] It can be understood that, in the embodiment, the first limiting piece 41 and the second limiting piece 42 are both limiting blocks made of elastic material. The first limiting piece 41 is arranged on the first end cover 21, and the second limiting piece 42 is arranged on the second end cover 31. When the first door body 20 and the second door body 30 are aligned, the first limiting piece 41 and the second limiting piece 42 abut against each other, thereby ensuring that the top surfaces of the two door bodies are flush. The first limiting piece 41 is made of elastic material (such as silicone, rubber, or polyurethane, etc.), and has certain elasticity and buffering property. The shape thereof can be block-shaped or columnar, and the top end is designed as a protruding part suitable for cooperating with the second limiting piece 42. Further, in order to ensure durability and accurate cooperation, the surface of the first limiting piece 41 can be designed as a circular or arc-shaped contact surface, thereby ensuring that uniform pressing force is generated when the contact is made. The second limiting piece 42 is arranged opposite to the first limiting piece 41 and is made of the same elastic material, and has a shape matched with the first limiting piece 41, i.e., a groove-shaped structure or a structure with an inner recess design. The groove design of the second limiting piece 42 should be accurately matched with the protruding part of the first limiting piece 41. When the door bodies are closed, the compressible contact force is generated between the first limiting piece 41 and the second limiting piece 42, thereby ensuring that the top surfaces of the two door bodies are flush when the two limiting pieces contact each other. The elastic limiting piece can provide uniform pressing force, thereby ensuring that the top surfaces of the two door bodies are accurately aligned when the door bodies are closed, and solving the problem of uneven top surfaces of the traditional double-door freezer 100 caused by flatness error. In addition, the design of the elastic material not only ensures that the top surfaces are flush, but also ensures that the door bodies are not interfered during the opening and closing process, thereby avoiding the influence of friction or blockage of the limiting piece on the smoothness of opening and closing.

[0055] Understandably, the first limiting member 41 has an arc-shaped groove on the side facing the second limiting member 42, and the second limiting member 42 has an arc-shaped protrusion on the side facing the first limiting member 41. This arc-shaped protrusion can be accommodated within the arc-shaped groove and press against the inner wall of the groove. The arc-shaped groove can be semi-circular, curved V-shaped, or other suitable curved shapes to ensure that the arc-shaped protrusion of the second limiting member 42 can be smoothly embedded and contact its inner wall. The shape of the arc-shaped protrusion should match the arc-shaped groove of the first limiting member 41, so that the contact between the two limiting members can occur stably and smoothly. The protruding portion of the second limiting member 42 can be arc-shaped or other suitable curved shapes to ensure a large contact area with the arc-shaped groove and uniform pressing force. When the first door 20 and the second door 30 are closed, the arc-shaped groove of the first limiting member 41 and the arc-shaped protrusion of the second limiting member 42 align. Due to the arc-shaped contact between the two, a uniform pressing force is generated, ensuring that the top surfaces of the two doors are flush. The arc-shaped design ensures that the contact surface has a certain self-alignment effect, making it less prone to slippage or misalignment, thereby improving alignment accuracy. At the same time, the arc-shaped contact surface design ensures that the first limiting member 41 and the second limiting member 42 will not generate excessive friction when the door is opened and closed. Due to the curved characteristics of the arc-shaped contact, the opening and closing action of the door can remain smooth, avoiding interference or jamming.

[0056] Understandably, the first limiting member 41 not only has an arc-shaped groove, but it also has an arc-shaped structure along the thickness direction of the first end cover, with the arc-shaped groove located in the middle of the first limiting member 41. Due to the curvature and position design of the arc, the opening and closing action of the door is smoother, avoiding interference or jamming when the door is opened or closed. This design effectively improves the user experience of the freezer 100 door, allowing users to easily open and close the door without worrying about malfunctions caused by jamming or unevenness.

[0057] like Figure 8 As shown, in the second embodiment, there are two sets of limiting components 40, and the two sets of limiting components are along the first direction (i.e., Figure 1The first direction is consistent with the length direction of the gap. The two limiting assemblies 40 each include a first limiting piece 41 and a second limiting piece 42. The first end cover 21 is provided with one first limiting piece 41 and one second limiting piece 42, and the second end cover 31 is also provided with one first limiting piece 41 and one second limiting piece 42. The first limiting piece 41 of the first end cover 21 and the second limiting piece 42 of the second end cover 31 are oppositely arranged, and the first limiting piece 41 of the second end cover 31 and the second limiting piece 42 of the first end cover 21 are oppositely arranged. Specifically, the first limiting piece 41 of the first end cover 21 is arranged at the first end of the first end cover 21, and the second limiting piece 42 is arranged at the second end of the first end cover 21. The first limiting piece 41 and the second limiting piece 42 of the second end cover 31 are oppositely arranged with the first limiting piece 41 and the second limiting piece 42 of the first end cover 21, that is, the first limiting piece 41 of the second end cover 31 is arranged at the second end of the second end cover 31, and the second limiting piece 42 is arranged at the first end of the second end cover 31. The first end of the above-mentioned end cover is the end away from the door body connected to the cabinet 10, and the second end is the end close to the door body connected to the cabinet 10. By designing the limiting assembly 40 as two groups, each group is composed of a first limiting piece 41 and a second limiting piece 42, which can provide more accurate and uniform limiting effect in two directions. The two groups of limiting pieces respectively play the positioning role in the up-down and left-right directions, which can better solve the door body deviation caused by manufacturing tolerance, material difference or external pressure.

[0058] Further, the two groups of limiting assemblies are arranged in the first direction (i.e. Figure 1 in the x-axis direction), and specifically, the first limiting piece 41 and the second limiting piece 42 arranged on the first end cover 21 are mirror-symmetrically arranged with the middle line section of the first end cover 21 as the reference surface, and the second limiting piece 42 and the first limiting piece 41 arranged on the second end cover 31 are mirror-symmetrically arranged with the middle line section of the second end cover 31 as the reference surface. The middle line of the end cover is in the x-axis direction, the middle position of the end cover, and the middle line section is a plane passing through the middle line of the end cover and perpendicular to the opening. The mirror-symmetric arrangement of the arrangement positions makes the positions of the limiting pieces on the two end covers symmetrical and consistent, which can ensure that the top surface of the door body is more accurately flush. Through the symmetry of the middle line section, the installation error of the limiting piece is effectively controlled, and the alignment accuracy of the door body is greatly improved. This mirror-symmetric design not only ensures the flushness of the top surface of the door body, but also effectively enhances the stability of the limiting piece structure. Due to the symmetrical distribution of the limiting pieces, the external force acting on the door body during use is more uniform, reducing the mechanical imbalance problem caused by asymmetry.

[0059] As Figures 9 to 12As shown, in the third embodiment, the limiting assembly 40 is arranged to be detachably coupled with the first end cover 21 and the second end cover 31, and the first end cover 21 or the second end cover 31 is arranged to be detached from the limiting assembly 40 when the relative force between the first end cover 21 and the second end cover 31 is greater than the preset force. The limiting assembly 40 is fixed to the end cover through corresponding connecting members (e.g., bolt holes, clamping slots, or elastic buckles), so as to ensure stable operation of the limiting assembly 40 during normal use. The detachable design of the limiting assembly 40 facilitates later maintenance and repair. Users do not need to replace the entire end cover, but only need to replace the limiting assembly 40. This not only reduces maintenance costs, but also improves maintenance efficiency, so that the maintenance of the freezer 100 is more convenient and efficient.

[0060] Specifically, the limiting assembly 40 includes a limiting member, the limiting member is provided with a buckle structure, and the first end cover 21 and the second end cover 31 are each provided with a clamping slot, and the buckle structure is clamped in the clamping slot.

[0061] Further, the limiting member includes a first limiting member 41 and a second limiting member 42, and the buckle structures of the first limiting member 41 and the second limiting member 42 are designed as rotating buckles. The buckle part of each limiting member presents a curved protruding structure and is connected with the clamping slot on the end cover through rotating cooperation. Specifically, the buckle part of the limiting member is provided with two symmetrical protruding teeth, which cooperate with the grooves in the clamping slot to ensure that the limiting member is firmly fixed to the end cover. The first end cover 21 and the second end cover 31 are each provided with a clamping slot matched with the buckle structure of the limiting member, and the inside of the clamping slot is designed as an arc-shaped notch, which is adapted to the curved shape of the protruding teeth of the limiting member. The end of each clamping slot is provided with a positioning hole for receiving the protruding teeth of the buckle part of the limiting member. When the protruding teeth of the limiting member are aligned with the clamping slot during installation, the limiting member is rotated along the direction of the clamping slot. Through the rotating action, the protruding teeth enter the groove part of the clamping slot and are finally positioned in the positioning hole, so as to firmly fix the limiting member to the end cover. When disassembling, the user can rotate the limiting member in the reverse direction to make the protruding teeth disengage from the clamping slot and be released from the fixation. The rotation angle during rotation is small, the disassembly process is simple, and no additional tools are required.

[0062] Further, the buckle structure is an elastic hook, and the limiting piece is connected to the clamping groove of the first end cover 21 and the clamping groove of the second end cover 31 through the elastic hook. The limiting piece includes a first limiting piece 41 and a second limiting piece 42, and the buckle structure is located on the opposite sides of each limiting piece and is designed as an elastic hook. Specifically, the first limiting piece 41 is provided with a first elastic hook 411, the second limiting piece 42 is provided with a second elastic hook 421, the first end cover 21 is provided with a first clamping groove 211 matched with the first elastic hook 411, and the second end cover 31 is provided with a second clamping groove 311 matched with the second elastic hook 421. The elastic hook is usually made of elastic plastic or rubber material, which can produce appropriate elastic deformation when inserted into the clamping groove, so as to ensure the close fit between the limiting piece and the clamping groove. One end of the hook is provided with a hook-shaped protrusion, which elastically clamps the inner wall of the clamping groove after the hook enters the clamping groove, thereby achieving the fixing effect. The clamping groove is usually a curved notch, which is shaped to be suitable for the hook-shaped protrusion of the elastic hook, so that the hook-shaped protrusion can be firmly fixed in the clamping groove. The design of the clamping groove can consider a certain tolerance to ensure that the limiting piece will not be stuck during installation and can be tightly fixed after installation. During installation, the elastic hook of the limiting piece is aligned with the clamping groove, and the user can directly push the limiting piece into the clamping groove. During this process, the elastic hook will be subjected to a certain pressure and will be elastically deformed, so that the hook-shaped protrusion is in contact with the inner wall of the clamping groove, and finally the limiting piece is fixed in the clamping groove. Due to the characteristics of the elastic hook, the installation and removal of the limiting piece become very simple. The installation process does not require any additional tools and can be completed by simply pushing. When disassembling, the user can pull the limiting piece gently to make the elastic hook separate from the clamping groove. Due to the elastic characteristics of the hook, the clamping groove or the limiting piece will not be damaged during disassembly. The disassembly operation is simple and fast, and the user does not need tools or complex operations to conveniently complete the disassembly of the limiting piece.

[0063] Further, the limiting piece has a rectangular structure, and the limiting piece has four peripheral edges, and the elastic hooks are arranged on the edges of the opposite sides. The limiting piece has a rectangular structure and has four edges, and the opposite edges are respectively provided with elastic hooks. The elastic hooks are located at the opposite ends of the limiting piece, and each hook has a curved hook-shaped protrusion which can be elastically deformed when inserted into the clamping groove. The design of the elastic hook ensures the close fit between the limiting piece and the inner wall of the clamping groove, and avoids the loosening of the limiting piece during use. The hook-shaped part of each hook will be deformed during the installation process, thereby being firmly fixed in the clamping groove. The use of the rectangular structure and the elastic hook design makes the installation and disassembly of the limiting piece more simple and fast. The user does not need additional tools, and the installation process only needs to be gently pushed, and the disassembly can also be completed by simply pulling.

[0064] In some embodiments, the first door body 20 and the second door body 30 are hinged to the same side of the cabinet 10 by the hinge structure 50. Specifically, the hinge structure 50 includes a hinge seat and a hinge shaft, the hinge seat is installed on the same side of the cabinet 10, and the hinge shaft is fixed on the door body. Each door body is connected with the hinge seat through at least one hinge shaft, both ends of the hinge shaft are fixed on the door body and the cabinet 10 respectively to form a pivot axis. When the door body needs to be opened or closed, the hinge shaft serves as the pivot point, and the door body rotates around the hinge shaft. The hinge structure 50 enables the first door body 20 and the second door body 30 to be opened and closed smoothly and smoothly, avoiding the difficulty of opening and closing the door body due to loose or unstable hinges.

[0065] In some embodiments, the first door body 20 and the second door body 30 are hinged to different sides of the cabinet 10, which can be opposite sides along the x-axis or opposite sides along the y-axis. Whether the hinge structure 50 is along the x-axis or the y-axis, it enables the two door bodies to be opened independently or simultaneously, increasing the flexibility of the door opening mode. Users can choose the opening angle and direction of the door body according to their needs, improving the convenience of operation.
