Description

Technical Field

[0001] This utility model relates to the field of display cabinet water collection tanks, and more particularly to a display cabinet water collection tank that is easy to assemble. Background Technology

[0002] Refrigerated display cases are refrigeration devices used in commercial environments, primarily for the refrigeration and display of food, beverages, and other goods. Therefore, the temperature inside the display case is very low. During opening and closing, outside air easily condenses into water, which then slides down the display case. Simultaneously, the low temperature causes a large amount of ice crystals to form inside the display case, which also detach during opening and closing. Therefore, a collection tank is typically installed inside the display case to collect the condensate and ice crystals generated during use.

[0003] Existing water tanks typically consist of an outer shell and an inner liner housed within it. The inner liner is usually a right-angled tank made by welding multiple stainless steel plates together. Therefore, during assembly, it is generally necessary to fully weld the four corners of the multiple sheet metal pieces used to make the tank to form the right-angled tank. The right-angled tank is then screwed onto the outer shell.

[0004] Therefore, manufacturing this water tank not only requires certain welding techniques, which is detrimental to productivity, but also makes the welded water tank prone to water leakage. A foam layer is usually placed between the water tank and the outer shell; when water leakage occurs at the weld joints, it can easily pose a hygiene and safety hazard to the product. Summary of the Invention

[0005] In view of this, the present invention provides a display cabinet water collection tank that is easy to assemble to solve the above problems.

[0006] A display case water collection tank for easy assembly includes a water tank and an outer casing spaced apart from the outside of the water tank. The water tank includes a base, two long side plates respectively disposed on both sides of the base, and two short side plates disposed perpendicular to the long side plates. The base includes a base body, a bent portion disposed around the perimeter of the base body, and a base mounting edge disposed around the perimeter of the bent portion. The base body, the bent portion, and the base mounting edge are integrally formed by die stamping. The cross-section of the bent portion is arc-shaped, and the size of the arc is set according to the water accumulation capacity of the display case. The long side plates and the short side plates abut against the base mounting edge and are fixedly screwed onto the mounting edge by rivets, with the long side plates and the short side plates abutting each other end to end.

[0007] Furthermore, the long side plate includes a long side plate body, a long side plate mounting edge disposed on the side of the long side plate body facing the chassis, a long side plate assembly edge disposed on the side of the long side plate body opposite to the chassis, and a water tank snap-fit ​​portion disposed at both ends of the long side plate assembly edge.

[0008] Furthermore, the short side plate includes a short side plate body, a short side plate mounting edge disposed on the side of the short side plate body facing the chassis, a short side plate assembly edge disposed on the side of the short side plate body opposite to the chassis, and two sealing edges respectively disposed at the two ends where the short side plate body connects to the long side plate.

[0009] Furthermore, at least one drainage hole is provided on the chassis body.

[0010] Furthermore, the outer box includes a box bottom, a long box plate disposed on one side of the box bottom along the length direction of the box bottom, a mounting positioning plate disposed on one side of the box bottom along the length direction of the box bottom, and two short box plates disposed perpendicular to the long box plate.

[0011] Furthermore, the long box panel includes a long box panel body, a long box panel mounting edge disposed on the side of the long box panel body facing the bottom of the box, a long box panel support edge disposed on the side of the long box panel body opposite to the bottom of the box, and a long box panel connecting flange disposed at both ends of the long box panel body.

[0012] Furthermore, the short box panel includes a short box panel body, a short box support edge disposed on the side of the short box panel body opposite to the bottom of the box, a short box panel connecting flange disposed on one end of the short box panel body facing the long box panel, an overlap joint disposed at both ends of the short box panel support edge, and at least one foam filling hole opened on the short box panel body.

[0013] Furthermore, the mounting positioning plate is integrally formed from the bottom of the box, which is made by bending the bottom of the box along its length.

[0014] Compared with existing technologies, the easily assembled display cabinet water tank provided by this utility model uses a chassis instead of a traditional tank bottom plate. The chassis includes a main body, a bent portion around the main body, and a mounting edge around the bent portion. The bent portion is arc-shaped, and the main body, the bent portion, and the mounting edge can be integrally formed by die stamping. Compared to a tank formed by right-angle welding, the integrally formed chassis has better sealing performance, eliminating the risk of leakage. Furthermore, the long and short side plates of the tank abut against the mounting edge during installation and are fixed to the mounting edge with rivets, thus reducing the technical requirements for workers in manufacturing the tank. Additionally, the outer casing, and the tank itself, are all assembled using screw connections, making installation and disassembly easy and greatly reducing the difficulty of maintenance.

[0020] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0021] like Figures 1 to 5The diagram shows a structural schematic of a display cabinet water collection tank that is easy to assemble, as provided by this utility model. The easy-to-assemble display cabinet water collection tank includes a water tank 10 and an outer casing 20 spaced apart from the outside of the water tank 10. It is conceivable that the easy-to-assemble display cabinet water collection tank should also include some other related functional components, such as installation components, assembly components, etc., all of which are prior art known to those skilled in the art and will not be described in detail here.

[0022] The water tank 10 includes a base 11, two long side plates 12 respectively disposed on both sides of the base 11, and two short side plates 13 disposed perpendicular to the long side plates 12. The water tank 10 is used to collect condensate and ice crystals during the use of the display case and drain them out.

[0023] The chassis 11 includes a chassis body 111, a bent portion 112 arranged around the chassis body 111, and a chassis mounting edge 113 arranged around the bent portion 112.

[0024] The chassis body 111 can be a square structure, which is used to collect condensation and ice crystals during the use of the display case. At least one drainage hole is provided on the chassis body 111, so that the water accumulated on the chassis body 111 can be drained out in time through the drainage hole, thereby avoiding leakage due to excessive water level.

[0025] The bent portion 112 is arranged along the outer contour of the chassis body 111, thereby forming a water-holding tray with the chassis body 111, giving the chassis 11 a certain water-holding capacity. The cross-section of the bent portion 112 is arc-shaped, and the size of the arc can be set according to the water accumulation capacity of the display case, thereby ensuring that the water-holding capacity of the chassis 11 meets the requirements.

[0026] The chassis mounting edge 113 is used to mount the long side plate 12 and the short side plate 13. It is set along the outer contour of the bent portion 112 and bent towards one side of the outer casing 20. A plurality of mounting holes are provided on the chassis mounting edge 113, and the long side plate 12 and the short side plate 13 can be screwed and fixed to the chassis mounting edge 113 through the mounting holes.

[0027] The chassis body 111, the bent portion 112, and the chassis mounting edge 113 can be integrally formed by die stamping, which is simple to manufacture. Moreover, compared with right-angle welding, the integrally formed chassis 11 has better sealing performance, eliminating the risk of water leakage and seepage, thereby preventing the foam layer from penetrating into the water tank 10 and causing hygiene and safety hazards.

[0028] The long side plate 12 is disposed on both sides of the chassis 11 along the length direction of the chassis 11, and includes a long side plate body 121, a long side plate mounting edge 122 disposed on the side of the long side plate body 121 facing the chassis 11, a long side plate assembly edge 123 disposed on the side of the long side plate body 121 opposite to the chassis 11, and a water tank snap-fit ​​part 124 disposed at both ends of the long side plate assembly edge 123.

[0029] The long side plate body 121 has a rectangular structure, and its length is adapted to the length of the chassis 11. The long side plate body 121 is assembled onto the chassis mounting edge 113 via the long side plate mounting edge 122, thereby forming the long side wall of the water tank 10.

[0030] Both the long side plate mounting edge 122 and the long side plate assembly edge 123 are formed by flanging the side of the long side plate body 121 facing the outer casing 10. The width of the long side plate mounting edge 122 is the same as the width of the chassis mounting edge 113. The long side plate mounting edge 122 is provided with mounting holes corresponding to the chassis mounting edge 113, and the long side plate mounting edge 122 and the chassis mounting edge 113 can be fixed together by fasteners such as rivets, thereby mounting the long side plate 12 onto the chassis 11.

[0031] The long side panel assembly edge 123 is used to assemble the water tank 10 onto the outer casing 20. The width of the long side panel assembly edge 123 is set according to the spacing requirements between the water tank 10 and the outer casing 20. One of the two long side panels 12 has an L-shaped cross-section of the long side panel assembly edge 123, which allows the L-shape to overlap one side of the outer casing 20 during assembly, thereby supporting the water tank 10 and facilitating its assembly onto the outer casing 20.

[0032] The water tank snap-fit ​​part 124 is formed by bending the long side plate body 121 after it extends along the length direction of the long side plate assembly 123. When assembling the water tank 10, the water tank snap-fit ​​part 124 snaps together with the outer box 20, thereby mounting the water tank 10 on the outer box 20, which will be described in detail below in conjunction with the outer box 20.

[0033] The short side plates 13 are disposed on both sides of the chassis 11 along the width direction of the chassis 11 and are fixedly screwed together with the long side plates 12 around each other, thereby forming the side wall of the water tank 10. The short side plates 13 include a short side plate body 131, a short side plate mounting edge 132 disposed on the side of the short side plate body 131 facing the chassis 11, a short side plate assembly edge 133 disposed on the side of the short side plate body 131 opposite to the chassis 11, and two sealing edges 134 respectively disposed at the two ends where the short side plate body 131 connects to the long side plate 12.

[0034] The short side plate body 131 can be a rectangular structure, the length of which is adapted to the width of the chassis 11, and it is connected end to end with the long side plate 12 to form the side wall of the water tank 10.

[0035] The short side plate mounting edge 132 is adapted to the chassis mounting edge 113. During assembly, it abuts against the chassis mounting edge 113 and is fixed together by rivets, thereby fixing the short side plate 13 to the chassis 11.

[0036] The width of the short side plate assembly edge 133 is set according to the spacing requirements between the water tank 10 and the outer casing 20. When the water tank 10 is assembled on the outer casing 20, the short side plate assembly edge 133 abuts against the outer casing 20 and forms a structural seal with the outer casing 20.

[0037] The sealing edge 134 is formed by bending both ends of the short side plate body 131 into a flange parallel to the long side plate body 121. When assembling the water tank 10, one side of the sealing edge 134 abuts against the long side plate body 121 and is fixed together by rivets, thereby forming a seal at the connection between the long side plate 12 and the short side plate 13, improving the sealing performance of the water tank 10, and thus preventing overflow and seepage when the water in the chassis 11 exceeds the volume of the chassis 11.

[0038] The outer box 20 includes a box bottom 21, a long box plate 22 disposed on one side of the box bottom 21 along the length direction of the box bottom 21, a mounting positioning plate 23 disposed on one side of the box bottom 21 along the length direction of the box bottom 21, and two short box plates 24 disposed perpendicular to the long box plate 22.

[0039] The bottom of the box 21 is also a rectangular plate structure. Flanged structures can be provided around the bottom of the box 21 for mounting the long box plate 22 and the short box plate 24, thereby facilitating the assembly of the long box plate 22 and the short box plate 24 onto the bottom of the box 21. It is understood that the bottom of the box 21 should also be provided with a water outlet corresponding to the drainage hole of the chassis 11. The drainage hole and the water outlet can be connected by a pipe, thereby facilitating the drainage of accumulated water inside the chassis 11.

[0040] The long box panel 22 is fixedly screwed onto the box bottom 21 along the length direction of the box bottom 21. It includes a long box panel body 221, a long box panel mounting edge 222 disposed on the side of the long box panel body 221 facing the box bottom 21, a long box panel support edge 223 disposed on the side of the long box panel body 221 opposite to the box bottom 21, and a long box panel connecting flange 224 disposed at both ends of the long box panel body 221.

[0041] The long box plate 22 is mounted on the box bottom 21 along the length of the flange structure along the length of the box plate 222 and abuts against each other, and is fixed together by rivets and screws, thereby mounting the long box plate 22 on the box bottom 21.

[0042] The long box plate support 223 is formed by bending the long box plate body 221 toward the side of the water tank 10. When the water tank 10 is assembled on the outer box 20, one side of the long box plate support 223 is attached to one side of the long side plate assembly 123, thereby forming a structural seal between the long side plate 12 and the long box plate 22.

[0043] The long box plate connecting flange 224 is formed into an L-shaped structure and is set at both ends of the long box plate body 221 along the height direction of the long box plate body 221. It is used to connect the long box plate 22 and the short box plate 24.

[0044] The mounting positioning plate 23 is integrally formed from the box bottom 21, and can be formed by bending the box bottom 21 along its length. The height of the mounting positioning plate 23 is the same as the height of the long box plate 22, so that the water tank 10 is in a horizontal state when installed inside the outer box 20. When assembling the water tank 10 and the outer box 20, the long side plate 12 of the assembly along the L-shaped mechanism of 123 overlaps with one side of the mounting positioning plate 23, thereby providing support for the water tank 10, so as to facilitate the assembly of the water tank 10 and the outer box 20.

[0045] The short box panel 24 includes a short box panel body 241, a short box support edge 242 disposed on the side of the short box panel body 241 opposite to the box bottom 21, a short box panel connecting flange 243 disposed on the end of the short box panel body 241 facing the long box panel 22, an overlap joint 244 disposed at both ends of the short box panel support edge 242, and at least one foam filling hole 245 opened on the short box panel body 241.

[0046] The short box plate support 242 is formed by bending the short box plate body 241 toward the side of the water tank 10. When the water tank 10 is assembled on the outer box 20, one side of the short box plate support 242 is attached to one side of the short side plate assembly 133, thereby forming a structural seal between the short side plate 13 and the short box plate 24.

[0047] The short box panel connecting flange 243 is L-shaped and is located at both ends of the short box panel body 241 along the height direction of the short box panel body 241. It is used to connect the long box panel 22 and the short box panel 24. When assembling the outer box 20, the long box panel 22, the mounting positioning plate 23, and the short box panel 24 are connected end to end to each other, and the short box panel connecting flange 243 and the long box panel connecting flange 224 are fitted together, thereby forming a structural seal between the short box panel 24 and the long box panel 22.

[0048] The interface 221 is matched with the sink snap-fit ​​part 124. When the sink 10 is installed on the outer box 20, the sink snap-fit ​​part 124 is inserted and overlapped at the interface 221, thereby mounting the sink 10 on the outer box 20.

[0049] The foam filling hole 245 is opened on the short box plate body 241. After the water tank is assembled, thermal insulation foam can be filled between the water tank 10 and the outer box 20 through the foam filling hole 245.

[0050] Compared with the prior art, the easy-to-assemble display cabinet water tank provided by this utility model has a base 11 on the water tank 10 instead of the existing water tank bottom plate. The base 11 includes a base body 111, a bent portion 112 arranged around the base body 111, and a base mounting edge 113 arranged around the bent portion 112. The bent portion 112 is arc-shaped, and the base body 111, the bent portion 112, and the base mounting edge 113 can be integrally formed by die stamping. Compared with the water tank formed by right-angle welding, the integrally formed base 11 has better sealing performance and will not have the risk of leakage or seepage. At the same time, the long side plate 12 and the short side plate 13 of the water tank 10 abut against the base mounting edge 13 during installation and are fixed to the mounting edge 13 by rivets, thereby reducing the technical requirements of workers in the manufacture of the water tank 10. Meanwhile, the outer casing 20, as well as the water tank 10 and the outer casing 20, are all assembled by screw connections, making installation and disassembly easy and greatly reducing the maintenance difficulty of the water tank 10.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
