Description

Technical Field

[0001] This application belongs to the field of commercial refrigerator technology, and particularly relates to a commercial refrigerator. Background Technology

[0002] Commercial horizontal glass-door freezers are typically placed in shopping malls, supermarkets, tourist attractions, convenience stores, and other locations to display and sell consumer goods that require freezing, such as ice cream and frozen foods. However, current commercial horizontal glass-door freezers usually use two sliding doors that slide left and right. On the one hand, this not only increases the complexity of the structure and manufacturing cost due to the need for multi-layered sliding tracks, affecting efficiency, safety, and user experience; on the other hand, the temperature difference between the outside air and the surface of the sliding doors causes condensation to form on the door surface. This condensation can easily flow into the freezer when the doors are opened and closed, increasing energy consumption and the risk of malfunction. It can also cause ice to form on the surface of the consumer goods, thus affecting their quality and usability. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a commercial refrigerator that reduces manufacturing and maintenance costs and difficulties by setting a door structure that is pivotally connected to the cabinet body and setting a water collection trough on the upper surface of the cabinet body near the cabinet opening, thereby improving usage efficiency, convenience and safety, and minimizing the risk of condensate flowing into the cabinet body, while ensuring the normal storage of items in the storage cavity and saving energy.

[0004] In a first aspect, this application provides a commercial freezer, comprising:

[0005] The cabinet body forms a receiving cavity with the cabinet opening facing upwards;

[0006] Two door structures, one side of which is away from the other door structure is pivotally connected to the cabinet body, and the other side of which can abut against the other door structure to jointly cover the cabinet opening;

[0007] A water collection trough is provided on the upper surface of the cabinet and surrounds the outside of the cabinet opening, for collecting condensate generated by the door structure.

[0008] According to the commercial freezer of this application, on the one hand, by pivotally connecting both door structures to the cabinet body, compared with the sliding doors used in related technologies, the structure is not only simpler, reducing manufacturing and maintenance costs and difficulties, but also allows for the selection of opening part or all of the cabinet openings as needed, improving efficiency and convenience, reducing the risk of pinching hands, and enhancing user safety. Furthermore, because condensate slides to the edge of the door structure when opening and closing, the possibility of condensate dripping directly into the cabinet body is reduced. On the other hand, by opening the water collection trough on the upper surface of the cabinet body and surrounding the outside of the cabinet opening, in conjunction with the pivot connection of the door structure, the risk of condensate flowing into the cabinet body can be minimized, saving energy while ensuring the normal storage of items in the storage cavity.

[0009] According to one embodiment of this application, the cabinet is provided with a drainage section, and the bottom surface of the water collection tank is inclined to guide the collected condensate into the drainage section.

[0010] According to one embodiment of this application, the water collection tank includes:

[0011] Two spaced-apart first groove segments extend in the left-right direction, and the bottom surface of the first groove segment slopes downward from the middle to the left and right ends.

[0012] Two spaced-apart second groove segments extend in a front-to-back direction, and each end of the second groove segment is connected to one of the two first groove segments; wherein the bottom surface of the second groove segment slopes downward in the front-to-back direction.

[0013] According to one embodiment of this application, the drainage section is provided at both ends of the front part of the cabinet, and the bottom surface of the second trough section slopes downward from back to front.

[0014] According to one embodiment of this application, the bottom surface of the water collection tank is a downwardly convex arc surface.

[0015] According to one embodiment of this application, the distance between the two oppositely arranged side walls of the water collection tank gradually decreases from top to bottom.

[0016] According to one embodiment of this application, in the vertical direction, a portion of the projection of the door structure and a portion of the projection of the water collection tank coincide.

[0017] According to one embodiment of this application, the upper surface of the cabinet is stepped to form a first surface and a second surface connected sequentially from the outside to the inside, the height of the first surface is higher than the height of the second surface, and the water collection trough is disposed on the second surface; wherein, when the door structure covers the cabinet opening, the upper surface of the door structure is not higher than the first surface.

[0018] According to one embodiment of this application, it also includes:

[0019] Two door seals are provided, each corresponding to a door structure. The door seals are located on the side of the door structure near the cabinet opening and are used to abut against the outer wall of the cabinet body near the cabinet opening. The water collection trough is located on the outside of the abutment point between the cabinet body and the door seal.

[0020] According to one embodiment of this application, in the vertical direction, a portion of the projection of the door seal and a portion of the projection of the water collection tank coincide.

[0045] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0046] The following is for reference. Figures 1-8 This application describes a commercial freezer provided in an embodiment, which includes a cabinet body 100 and two door structures 200.

[0047] Unless otherwise specified, the front-back direction in this application refers to the width direction of the cabinet 100; the left-right direction refers to the length direction of the cabinet 100; and the up-down direction refers to the height direction of the cabinet 100.

[0048] The cabinet 100 forms a receiving cavity with the cabinet opening 101 facing upwards, allowing users to retrieve or place items from the receiving cavity through the cabinet opening 101. The material of the cabinet 100 may include, but is not limited to, stainless steel, aluminum alloy, or titanium alloy. It should be noted that the shape and size of the cabinet 100, the cabinet opening 101, and the receiving cavity can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0049] The side of door structure 200 away from another door structure 200 is pivotally connected to cabinet 100, and the other side of door structure 200 can abut against another door structure 200 to jointly cover cabinet opening 101, and door structure 200 is transparent.

[0050] It should be noted that in this embodiment, the transparent setting of the door structure 200 means that the plastic frame is removed, realizing a frameless structure of the door structure 200. This maximizes the display area, reduces the number of parts, and avoids problems such as dust accumulation, blackening, and bacterial growth in the gaps of the frame due to the outflow of condensation and inconvenience of cleaning, as well as fading and discoloration of the frame after long-term use. This ensures the storage safety of items inside the cabinet 100 and the aesthetics of the commercial refrigerator as much as possible.

[0051] Understandably, on the one hand, by arranging the two door structures 200 opposite each other in the left-right direction and pivotally connected to the cabinet 100, compared to the sliding doors using left-right pushing and pulling in related technologies, the structure is not only simpler, reducing manufacturing and maintenance costs and difficulties, but also allows for the selection of opening part or all of the cabinet opening 101 as needed, improving efficiency and convenience, reducing the risk of pinching fingers, and enhancing user safety. On the other hand, since the two door structures 200 abut against each other on their closest sides and the door structures 200 are transparent, the display area can be maximized, reducing the possibility of obstructing the view and improving the user experience. In addition, since the cabinet opening 101 faces upwards, the door structure 200 can fully utilize its own weight to improve the sealing of the cabinet opening 101, reducing the risk of cold air leakage, thereby improving energy efficiency and reducing frost formation.

[0052] Meanwhile, compared to sliding doors that push and pull left and right in related technologies, the pivot connection between the door structure 200 and the cabinet 100 has several advantages. First, when the door structure 200 is opened and closed, condensate will slide to the edge on the surface of the door structure 200, thereby reducing the possibility of condensate dripping directly into the cabinet 100. This saves energy while ensuring the normal storage of items in the cavity. Second, the pivot connection enhances the anti-theft performance and facilitates the installation of locks.

[0053] The commercial freezer provided in the embodiments of this application has two transparent door structures 200 that are pivotally connected to the cabinet body 100 and can abut against each other, which reduces the cost and difficulty of manufacturing and maintenance, improves the efficiency, convenience and safety of use, maximizes the display area, reduces the possibility of obstructing the view, improves the user experience and reduces the risk of cold air leakage.

[0054] In some embodiments, such as Figures 1 to 3 As shown, the door structure 200 includes a door body 210 and a sealing strip 220. One side of the door body 210 is pivotally connected to the cabinet 100. The sealing strip 220 is disposed on the other side of the door body 210 to abut against and cooperate with the sealing strip 220 of another door structure 200.

[0055] It is understood that the two sealing strips 220 are positioned opposite each other in the left-right direction between the two door bodies 210 to provide a seal when the cabinet opening 101 is completely covered. The material of the sealing strip 220 includes, but is not limited to, transparent PVC (polyvinyl chloride), which not only has good transparency but also high wear resistance and impact resistance. The connection between the sealing strip 220 and the door body 210 includes, but is not limited to, adhesive bonding. It should be noted that the cross-section of the sealing strip 220 includes, but is not limited to, D-shaped, P-shaped, T-shaped, or wedge-shaped shapes; this embodiment does not impose specific limitations on these. In addition, compared to the related technology where the outer perimeter of the door body 210 is covered with a plastic frame, the transparent door body 210 and the sealing strip 220 located on the side of the door body 210 closest to the other door body 210 can further reduce manufacturing costs and assembly processes, making subsequent structural upgrades and iterations more flexible.

[0056] In some embodiments, the door 210 includes a tempered glass layer and a coating layer stacked from the outside to the inside.

[0057] It is understandable that by setting a tempered glass layer to meet the requirement of transparency and visibility while maximizing strength and safety, and by applying a coating layer to the side of the tempered glass layer near the cabinet opening 101, not only can light reflection be reduced, further improving the transparency of the door 210, but also heat exchange between the inside and outside can be reduced, increasing thermal insulation performance. It should be noted that the thickness of the tempered glass layer and the coating layer can be designed according to actual needs; this embodiment does not impose specific limitations on this.

[0058] In some embodiments, the door 210 also includes a screen printing layer disposed on the side of the tempered glass layer away from the cabinet opening 101, so as to add patterns, text or trademarks to the surface of the tempered glass layer, thereby enhancing the display effect and personalization of the items.

[0059] In some embodiments, such as Figures 3 to 5As shown, the commercial freezer also includes two door seals 300, each corresponding to a door structure 200. The door seals 300 are located on the side of the door structure 200 near the cabinet opening 101, and are used to abut against the outer wall of the cabinet body 100 near the cabinet opening 101. The connection between the door seals 300 and the door structure 200 includes, but is not limited to, adhesive bonding. The material of the door seals 300 includes, but is not limited to, rubber.

[0060] Understandably, by providing a door seal 300 on the lower surface of the door 210, the door seal 300 can tightly abut against the outer wall of the cabinet 100 near the cabinet opening 101 when the cabinet opening 101 is fully closed, thereby forming an effective seal and preventing cold air leakage. At the same time, it can also provide a cushioning, shock absorption, and noise reduction effect when the door is closed.

[0061] In some embodiments, the door seal 300 is provided with at least one deformation cavity to ensure a sealed connection between the door structure 200 and the cabinet opening 101 through deformation of the deformation cavity. It should be noted that the number, size, and shape of the deformation cavity can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0062] In some embodiments, such as Figures 1 to 5 As shown, the projections of the door seal 300 in the vertical direction and the cabinet opening 101 in the vertical direction are spaced apart in the horizontal direction, thereby avoiding the door seal 300 from partially obscuring the cabinet opening 101 when the door structure 200 is in the position of covering the cabinet opening 101, thus reducing the display area and the possibility of obstructing the view.

[0063] In some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the commercial freezer also includes two hinge structures 400 arranged opposite each other. The hinge structure 400 corresponds one-to-one with the door structure 200, and the door structure 200 is pivotally connected to the cabinet body 100 through the hinge structure 400.

[0064] It is understandable that by setting hinge structures 400 on the left and right sides of the cabinet 100 respectively, the two doors 210 are pivotally connected to the cabinet 100, and the pivot point of the door 210 is located at the end of the cabinet 100, so as to avoid affecting the display area and obstructing the view when the pivot point of the door 210 is located in the middle of the cabinet 100.

[0065] In some embodiments, such as Figure 5As shown, the hinge structure 400 includes a fixed base 410, a movable part 420, a movable rod 430, and an elastic element 440. The fixed base 410 is installed on the outer side wall of the cabinet 100. One side of the movable part 420 is installed on the door structure 200, and the other side is rotatably connected to the fixed base 410. The movable rod 430 is movably disposed in the fixed base 410 and moves synchronously with the movable part 420. The elastic element 440 is installed in the fixed base 410 and sleeved on the movable rod 430. When the movable part 420 rotates relative to the fixed base 410, the movable rod 430 moves and causes the elastic element 440 to deform, so as to achieve suspension.

[0066] It should be noted that the fixed base 410 is installed on the left or right outer wall of the cabinet 100, providing support for the opening and closing of the door 210; one side of the movable part 420 is installed on the door 210, and the other side is rotatably connected to the fixed base 410 via a pivot shaft 450, thereby enabling the movable part 420 to rotate along the front and rear axis; at the same time, since the movable rod 430 is located in the receiving cavity of the fixed base 410 and moves synchronously with the movable part 420, the movable rod 430 moves up and down when the movable part 420 rotates, thereby causing the elastic element 440 sleeved outside the movable rod 430 to deform, and causing one of the multiple first limiting elements provided on the movable rod 430, which are spaced apart in the up and down direction, to engage with the second limiting element connected to the elastic element 440, thereby using the rebound force of the elastic element 440 to achieve the suspension of the door structure 200, and using the second limiting element and different first limiting elements to achieve the angle change when the door structure 200 is suspended.

[0067] It is understood that by giving the hinge structure 400 a hovering function, it is not only easier to pick up and put down items, but also reduces potential harm to users and items, and improves safety during use. Exemplarily, one of the first and second limiting members is a limiting groove, and the other is a limiting block; this embodiment does not impose specific limitations on this.

[0068] In this embodiment, as Figure 5 As shown, the hinge mechanism also includes a drive shaft 460 and a connector 470. The drive shaft 460 is connected to the pivot shaft 450 and cooperates with the guide groove 411 opened on the fixed seat 410. The inner side wall of the connector 470 contacts and cooperates with the outer side wall of the drive shaft 460. The outer side wall of the connector 470 is connected to one end of the movable rod 430.

[0069] It is understandable that when the pivot shaft 450 rotates, the transmission shaft 460 rotates and its end moves in the guide groove 411, thereby causing the spatial position of the connecting piece 470 to change, thus realizing the up and down movement of the movable rod 430.

[0070] In some embodiments, such as Figure 1As shown, the commercial freezer also includes a water collection structure 500, which is installed in the cabinet 100 to collect condensate generated by the door structure 200.

[0071] Understandably, by setting a water collection structure 500 in the cabinet 100, the condensate water generated by the temperature difference between the inside and outside of the door 210 during the use of the freezer or external water is not easily allowed to enter the cabinet 100 through the cabinet opening 101. It also facilitates regular cleaning and improves the waterproofness and refrigeration efficiency of the commercial freezer.

[0072] In some embodiments, such as Figures 2 to 4 As shown, the water collection structure 500 includes a water collection trough 510, which is located on the upper surface of the cabinet 100 and surrounds the outside of the cabinet opening 101.

[0073] It is understood that by placing the water collection trough 510 on the upper surface of the cabinet 100 and surrounding the outside of the cabinet opening 101, it helps to directly collect the condensate generated by the door structure 200, preventing the condensate adhering to the door structure 200 from sliding off the cabinet 100 when the door is opened and closed, thus preventing potential slippage hazards or damage to the freezer. It should be noted that the size of the water collection trough 510 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0074] In some embodiments, such as Figure 4 As shown, the water collection structure 500 also includes a drain section 520 provided on the cabinet 100. The bottom surface of the water collection tank 510 is inclined to guide the collected condensate into the drain section 520.

[0075] Understandably, the inclined bottom of the water collection tank 510 not only accelerates the flow of condensate but also utilizes gravity to concentrate the condensate in the drain section 520, facilitating its collection and discharge. This reduces the risk of condensate buildup and overflow in the water collection tank 510, helping to maintain the hygiene of the freezer and its surrounding environment. It should be noted that the inclination direction and angle of the water collection tank 510 can be designed according to actual needs; this embodiment does not impose specific limitations on this.

[0076] In some embodiments, such as Figure 4 As shown, the water collection tank 510 includes two spaced-apart first tank sections 511 and two spaced-apart second tank sections 512: the first tank section 511 extends in the left-right direction, and the bottom surface of the first tank section 511 slopes downward from the middle to the left and right ends; the second tank section 512 extends in the front-back direction, and the two ends of the second tank section 512 are respectively connected to the two first tank sections 511; wherein, the bottom surface of the second tank section 512 slopes downward in the front-back direction.

[0077] Understandably, since the bottom surfaces of the two first trough sections 511, which are spaced apart along the front-back direction, slope downwards from the middle to the left and right ends, it is convenient for the condensate in the first trough section 511 to be concentrated at the left and right ends of the first trough section 511. At the same time, since the bottom surface of the second trough section 512, which is spaced apart along the direction of action, slopes downwards along the front-back direction, and the second trough section 512 is connected to the first trough section 511 to form a closed water collection path, it is convenient for the condensate in the first trough section 511 and the condensate in the second trough section 512 to be concentrated at the lower end of the front and rear ends of the second trough section 512, thereby further improving drainage efficiency and facilitating the installation of the drainage section 520.

[0078] In some embodiments, such as Figure 4 As shown, drainage sections 520 are provided at both ends of the front part of the cabinet 100, and the bottom surface of the second groove section 512 slopes downward from back to front.

[0079] Understandably, the drainage section 520 includes drainage holes, with two drainage holes respectively located on the front of the left and right inner side walls of the cabinet 100. These drainage holes correspond one-to-one with and are connected to the second groove section 512, allowing condensate to flow quickly to the front of the second groove section 512 and exit through the corresponding drainage holes. Furthermore, the location of the drainage holes at the front of the cabinet 100 facilitates adaptation to user habits.

[0080] In some embodiments, such as Figures 2 to 4 As shown, the bottom surface of the water collection tank 510 is a downwardly convex arc surface. It should be noted that the curvature of the arc surface can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0081] Understandably, the downward-convex curved surface can guide condensate more effectively than a flat surface, reduce the obstruction of condensate flow, help prevent condensate from accumulating locally at the bottom of the sink, reduce the risk of bacterial growth caused by water accumulation, and adapt to the situation where the cabinet is placed on uneven ground.

[0082] In some embodiments, the distance between two oppositely arranged sidewalls of the water collection tank 510 gradually decreases from top to bottom.

[0083] Understandably, by tilting the two oppositely arranged side walls of the water collection tank 510 towards each other from top to bottom, the flow rate of condensate water is further increased, thereby improving drainage efficiency.

[0084] In some embodiments, such as Figures 2 to 4 As shown, in the vertical direction, a portion of the projection of the door structure 200 coincides with a portion of the projection of the water collection tank 510.

[0085] Understandably, since the partial projections of the door body 210 and the water collection trough 510 in the vertical direction overlap—that is, the projections of parts of the door body 210 fall on the first trough segment 511 and the second trough segment 512 respectively in the vertical direction—not only does this make the structure more compact, but it also facilitates the direct flow of condensate from the overlapping projections of the door body 210 and the water collection trough 510 into the water collection trough 510, simplifying the drainage path and improving drainage efficiency. Furthermore, because the door seal 300 creates a certain gap between the door body 210 and the water collection trough 510 in the vertical direction, the water collection trough 510 acts as a handle, making it easier for shorter users to open the door structure 200, further improving the user experience.

[0086] In some embodiments, such as Figures 2 to 4 As shown, the upper surface of the cabinet 100 is stepped to form a first surface 102 and a second surface 103 connected sequentially from the outside to the inside. The height of the first surface 102 is higher than the height of the second surface 103, and the water collection tank 510 is disposed on the second surface 103. When the door structure 200 covers the cabinet opening 101, the upper surface of the door structure 200 is not higher than the first surface 102.

[0087] Understandably, since the second surface 103 with the water collection trough 510 is lower than the first surface 102, it facilitates the guidance of condensate flow to the water collection trough 510 and reduces the possibility of condensate overflowing from the water collection trough 510 to the outside of the cabinet 100. Simultaneously, because the upper surface of the door structure 200 is not higher than the first surface 102, the door structure 200 does not protrude from the cabinet 100 when the cabinet opening 101 is closed, increasing the aesthetics of the commercial refrigerator and concealing the water collection trough 510 and the door seal 300, providing a certain degree of protection and making the packaging and transportation of the commercial refrigerator safer and more reliable.

[0088] In some embodiments, such as Figures 2 to 4 As shown, the water collection tank 510 is located on the outside of the junction between the cabinet 100 and the door seal 300.

[0089] Understandably, since the water collection trough 510 is located on the outer side where the cabinet 100 and the door seal 300 abut, it avoids the possibility of condensate being collected in the water collection trough 510 and dripping directly into the cabinet 100. It effectively collects condensate generated at the contact point between the door seal 300 and the cabinet 100 without interfering with the sealing performance of the door seal 300 to the cabinet opening 101. At the same time, it also reduces the difficulty of maintaining the water collection trough 510, allowing cleaning without opening the door 210.

[0090] In some embodiments, such as Figures 2 to 4 As shown, in the vertical direction, a portion of the projection of the door seal 300 coincides with a portion of the projection of the water collection tank 510.

[0091] Understandably, the projections of some door seals 300 in the vertical direction fall into the first groove segment 511 and the second groove segment 512 respectively, which helps to save the overall space of the commercial freezer and make the overall structure more compact. At the same time, it also helps to directly collect the condensate generated at the door seals 300 and reduce the risk of condensate overflow.

[0092] In some embodiments, such as Figure 1 , Figure 3 , Figures 6 to 8 As shown, the commercial freezer also includes a handle structure 600, which is disposed on the door structure 200 and has an unlocked state and a locked state. When the handle structure 600 is in the unlocked state, it is used to allow relative movement between the two door structures 200. When the handle structure 600 is in the locked state, it is used to fix the two door structures 200 relative to each other, and the two door structures 200 together cover the cabinet opening 101.

[0093] Understandably, by setting the handle structure 600, it is not only convenient for users to apply force to open and close the door structure 200, but also integrates the function of a lock into the handle structure 600. This not only increases the flexibility of use, but also improves the security of commercial refrigerators, saves space, reduces the cumbersomeness of maintenance and disassembly, and also increases aesthetics and improves the user experience.

[0094] In some embodiments, such as Figures 6 to 8 As shown, the handle structure 600 includes a mating member 610, a locking member 620, and an operating part 630. The mating member 610 is disposed in one of the door structures 200; the locking member 620 is movably disposed in the other door structure 200 for locking or disengaging with the mating member 610; the operating part 630 is configured to drive the locking member 620 toward or away from the mating member 610.

[0095] It is understood that the mating part 610 is disposed on one of the door bodies 210 near the other door body 210, and the locking part 620 is disposed on the other door body 210. Both the mating part 610 and the locking part 620 are located on the side of the corresponding door body 210 away from the pivot connection with the cabinet body 100. That is, in the vertical direction, the projection of the mating part 610 and the locking part 620 is located in the middle of the cabinet opening 101. That is, the user drives the locking part 620 to move closer to or away from the mating part 610 by operating the operating part 630, thereby realizing the locking engagement or disengagement of the locking part 620 and the mating part 610, thereby realizing the interlocking or unlocking between the two door structures 200.

[0096] In some embodiments, if cost is not a concern, the handle structure 600 further includes a reset member, which is connected to the locking member 620 and the corresponding door structure 200 respectively. The locking member 620 is a permanent magnet, the mating member 610 is an electromagnet or an electromagnetic coil, and the operating part 630 includes an electromagnetic switch, which controls the on / off state of the current applied to the mating member 610. The reset member includes, but is not limited to, a spring.

[0097] Understandably, when it is necessary to lock the door 210, the user can turn on the electromagnetic switch to energize the mating part 610, thereby creating an attraction between the mating part 610 and the locking part 620. This causes the locking part 620 to move closer to the mating part 610 and connect with it, thus achieving interlocking between the two door bodies 210. When it is necessary to open the door 210, the user only needs to turn off the electromagnetic switch to de-energize the mating part 610, thereby eliminating the attraction between the mating part 610 and the locking part 620. The locking part 620 can be reset by the action of the reset member to disengage from the mating part 610, thereby unlocking the two door bodies 210 and allowing the door structure 200 to be opened and closed at will.

[0098] In some embodiments, such as Figure 7 and Figure 8 As shown, the mating part 610 has a slot 611, and the locking part 620 includes a mounting base 621 and a lock body 622. The mounting base 621 is installed on the door structure 200, and the mounting base 621 has a sliding groove 6211, and the slot of the slot 611 and the slot of the sliding groove 6211 are arranged opposite to each other. The lock body 622 is at least partially located in the sliding groove 6211, and the lock body 622 is movably disposed on the mounting base 621 to engage or disengage with the slot 611. The lock body 622 and the operating part 630 are detachably connected.

[0099] It is understood that the slots of the card slot 611 and the slide groove 6211 are arranged opposite each other in the left-right direction. By installing the mounting base 621 on the door body 210 and opening the slide groove 6211 to guide the movement direction of the lock body 622, when it is necessary to lock the door body 210, the user can use the operating part 630 to drive the lock body 622 to slide in the slide groove 6211 and at least partially penetrate into the card slot 611, thereby achieving interlocking between the two door bodies 210. When it is necessary to open the door body 210, the user can use the operating part 630 to drive the lock body 622 to slide in the opposite direction in the slide groove 6211 to exit the card slot 611 until the vertical projection of the lock body 622 completely falls on the door body 210 where the mounting base 621 is located, thereby achieving unlocking between the two door bodies 210, thus facilitating the opening and closing of the door structure 200 at will. In addition, the operating part 630 and the lock body 622 are detachably connected to further improve the security of the commercial refrigerator. Meanwhile, by providing a slot 611 in the mating part 610, a slide groove 6211 in the mounting base 621, and a lock body 622 movably mounted on the mounting base 621, a mechanical locking method is provided, which has low manufacturing and maintenance costs and a wide range of applications and is flexible.

[0100] It should be noted that the connection between the mating part 610 and the door body 210, and the connection between the mounting base 621 and the door body 210, include but are not limited to threaded connections and snap-fit ​​connections. The materials of the mating part 610, the mounting base 621, and the lock body 622 include but are not limited to hard plastic, stainless steel, aluminum alloy, or titanium alloy.

[0101] In some implementations, such as Figure 8 As shown, the lock body 622 includes a main body 6221 and a lock cylinder 6222. The main body 6221 is rotatably connected to the mounting base 621 and is at least partially located in the slide groove 6211. The rotation axis of the main body 6221 is parallel to the orientation of the cabinet opening 101. One end of the lock cylinder 6222 is connected to the main body 6221, and the other end is adapted to extend out of the slide groove 6211 to engage with the slot 611.

[0102] Understandably, by rotating the operating part 630, the main body 6221 drives the lock cylinder 6222 to rotate along the upper and lower axes, thereby causing part of the lock cylinder 6222 to extend into or retract from the slot 611, achieving the engagement or disengagement of the lock body 622 and the slot 611. Furthermore, since the rotation axis of the main body 6221 is parallel to the orientation of the cabinet opening 101, the compatibility between the lock body 622 and the cabinet 100 is improved, better conforming to the user's operating habits.

[0103] In some implementations, such as Figure 7 and Figure 8As shown, the mounting base 621 includes a connected mounting block 6212 and a mounting plate 6213. The upper surface of the mounting block 6212 is provided with a notch. The mounting plate 6213 is installed at the notch and forms a sliding groove 6211 with the mounting block 6212. That is, the upper surface of the lock cylinder 6222 slides with the lower surface of the mounting plate 6213, and the lower surface and outer wall of the lock cylinder 6222 slide with the upper part of the mounting block 6212. The upper surface of the mounting block 6212 at the notch is provided with a positioning shaft. The lower surface of the main body 6221 is provided with a positioning hole that matches the positioning shaft. That is, the positioning shaft passes through the positioning hole to radially limit the main body 6221, ensuring the stability of the connection between the mounting base 621 and the lock body 622.

[0104] In some implementations, such as Figure 8 As shown, the sidewall of the lock cylinder 6222 has a first arc surface 641, and the sidewalls of the slot 611 and the slide groove 6211 both have a second arc surface 642 that mates with the first arc surface 641. Furthermore, the axes of the first arc surface 641 and the second arc surface 642 coincide with the rotation axis of the main body 6221. It should be noted that the radius and shape of the first arc surface 641 and the second arc surface 642 can be designed according to actual needs; this embodiment does not impose specific limitations on this.

[0105] Understandably, both the first arc surface 641 and the second arc surface 642 protrude in directions away from each other, and the axes of the first arc surface 641 and the second arc surface 642 coincide with the rotation axis of the main body 6221. This ensures the concentricity and consistency of the lock cylinder 6222 during rotation, and ensures that the side wall of the lock cylinder 6222 is always in contact with at least one of the side wall of the slot 611 and the side wall of the slide groove 6211. This helps to improve the smoothness and reliability of the lock body 622's rotation, provides precise positioning of the lock cylinder 6222, makes the locking effect better, and provides a smoother and more aesthetically pleasing appearance.

[0106] In some implementations, such as Figure 8 As shown, the mounting base 621 has a first clearance hole 6214, and the main body 6221 has a locking hole 62211. One end of the operating part 630 passes through the first clearance hole 6214 and cooperates with the locking hole 62211 to drive the main body 6221 to rotate relative to the mounting base 621.

[0107] It is understood that the first clearance hole 6214 is formed on the mounting plate 6213, thereby providing clearance space for the operating part 630 so that one end of the operating part 630 can be inserted and engaged with the lock hole 62211 on the main body 6221. Then, by rotating the other end of the operating part 630, the main body 6221 and the lock cylinder 6222 can be rotated to achieve interlocking and unlocking between the door 210. It should be noted that the shape and size of the first clearance hole 6214 and the lock hole 62211 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0108] In some embodiments, such as Figures 6 to 8 As shown, the handle structure 600 also includes a first half-shell 650 and a second half-shell 660. The first half-shell 650 and the mating part 610 are respectively disposed on the outer and inner sides of one of the door structures 200, and the projection of the mating part 610 in the vertical direction is located within the projection of the first half-shell 650 in the vertical direction. The second half-shell 660 and the locking part 620 are respectively disposed on the outer and inner sides of one of the door structures 200. When the locking part 620 and the mating part 610 are disengaged, the projection of the locking part 620 in the vertical direction is located within the projection of the second half-shell 660 in the vertical direction.

[0109] Understandably, by positioning the mating part 610 and the locking part 620 on the lower surface of the corresponding door body 210, and the first half-shell 650 and the second half-shell 660 on the upper surface of the corresponding door body 210, the opening and closing structure 200 is facilitated while further improving the safety of the commercial freezer. Simultaneously, since the mating part 610 is always located within the vertical projection of the first half-shell 650, when the locking part 620 and the mating part 610 are disengaged, the projection of the locking part 620 is located within the vertical projection of the second half-shell 660. This effectively conceals the locking part 620 and the mating part 610, minimizing the risk of accidental movement or interference with the locking part 620, thus enhancing the safety of the commercial freezer.

[0110] It should be noted that the connection between the first half-shell 650 and the door body 210, and the connection between the second half-shell 660 and the door body 210, include, but are not limited to, threaded connections and snap-fit ​​connections. The materials of the first half-shell 650 and the second half-shell 660 include, but are not limited to, hard plastic, stainless steel, aluminum alloy, or titanium alloy.

[0111] In some embodiments, such as Figures 6 to 8 As shown, the second half-shell 660 has a second clearance hole, and the door structure 200 corresponding to the second half-shell 660 has a third clearance hole. The second clearance hole and the second clearance hole are used to avoid the operating part 630.

[0112] It is understood that one end of the operating part 630 passes through the second clearance hole, the third clearance hole, and the first clearance hole 6214 in sequence and then engages with the lock hole 62211, thereby enabling the lock cylinder 6222 on the inside of the door body 210 to move closer to or away from the slot 611 from the outside of the door body 210. It should be noted that the shape and size of the second clearance hole and the third clearance hole can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0113] In some embodiments, such as Figures 6 to 8 As shown, the top surfaces of the first half-shell 650 and the second half-shell 660 are respectively provided with a first slot 651 and a second slot 661; wherein, when the two door structures 200 jointly cover the cabinet opening 101, the first slot 651 and the second slot 661 are joined together to form a receiving groove.

[0114] Understandably, by providing the first slot 651 and the second slot 661, it is easier for the user to grip the first half-shell 650 or the second half-shell 660, which helps to open or close the cabinet opening 101. Furthermore, the mating of the first slot 651 and the second slot 661 allows the two door structures 200 to form a closed receiving groove when closed, and the second clearance hole is located at the bottom of the receiving groove, thereby accommodating the operating part 630 and providing space for its rotation, while also contributing to improving the overall aesthetics of the commercial refrigerator.

[0115] In this embodiment, the projections of the first half-shell 650 and the second half-shell 660 along the vertical direction are both D-shaped, and the projection of the receiving groove along the vertical direction is elliptical, which increases the aesthetics of the commercial freezer.

[0116] In some embodiments, such as Figure 8 As shown, at least one of the first half-shell 650 and the second half-shell 660 has its edge bent downward and is spaced apart from the door structure 200 in the vertical direction.

[0117] Understandably, by bending the edge of the outer wall of at least one of the first half-shell 650 and the second half-shell 660 downwards, the mechanical strength and stability of the handle structure 600 are increased. The bending of the lower surface and the upper surface of the door 210 are spaced apart, which facilitates repeated gripping during daily use and reduces the contact area between the first half-shell 650 and the second half-shell 660 and the surface of the corresponding door 210. This helps maintain the sealing performance of the commercial freezer, reduces the possibility of cold air leakage, and also increases the aesthetics of the commercial freezer.
