Description

Technical Field

[0001] This utility model relates to the field of food storage equipment technology, and in particular to a food insulation device. Background Technology

[0002] Typical food warming racks are composed of multiple racks, so when they are packed and shipped, they are bulky and have high transportation and packaging costs. Therefore, it is usually chosen to disassemble the countertop and the uprights and then stack them for packaging. However, after installing the heat lamp, the existing racks will form a protrusion at the heat lamp, which makes it impossible to stack multiple racks horizontally in sequence when packing. After packing, the volume of the entire equipment needs to be too large, which is not conducive to reducing transportation costs. Utility Model Content

[0003] The purpose of this utility model is to provide a food warming device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A food warming device, comprising:

[0006] There are two uprights arranged in a left-right direction;

[0007] At least two shelves are arranged vertically. Each shelf is detachably connected to one of the two uprights on its left and right sides. The projections of the shelves and the uprights on any vertical and horizontal plane are rectangular. The upper side of the lower shelf serves as a support platform, and the upper shelf is equipped with a heat-insulating lamp assembly. The emitter of the heat-insulating lamp assembly extends through the lower side of the upper shelf. A clearance cavity is provided at the bottom of the upper shelf. The bottom height of the emitter of the heat-insulating lamp assembly is greater than the height of the lower side of the upper shelf.

[0008] This technical solution has at least the following beneficial effects: When packaging and transporting food warming equipment, the uprights and shelves are first disassembled and separated, and then the shelves and uprights are packed and stacked. Because the heat preservation lamps in the shelves are hidden in the recessed cavity, if the upper shelves are stacked elsewhere, they will only abut against the edge of the recessed cavity, allowing the shelves to be placed horizontally. The top of the shelves is a flat support platform. At this time, whether the shelves are stacked one to another or the shelves and uprights are packed and stacked, the rectangular shelves and uprights can be placed flat without protrusion, which greatly reduces the space required for packaging and saves transportation costs.

[0009] As a further improvement to the above technical solution, each shelf includes an interconnected outer frame and a base plate, forming an installation space between the outer frame and the base plate. The heat-insulating lamp assembly includes a heat-insulating lamp, a lamp holder, and a connecting frame. The connecting frame, the lamp holder, and the heat-insulating lamp are all located in the installation space. The connecting frame is connected to the base plate, the lamp holder is connected to the connecting frame, and the heat-insulating lamp is electrically connected to the lamp holder.

[0010] As a further improvement to the above technical solution, the connecting frame includes a crossbeam and legs. The crossbeam is connected to a set of legs in the left and right directions respectively. The end of the legs away from the crossbeam extends downward. The lamp holder is connected to the crossbeam and located between the two sets of legs.

[0011] As a further improvement to the above technical solution, each group includes at least two legs, and a mounting groove matching the outer wall of the lamp holder is formed between the two legs in the same group.

[0012] As a further improvement to the above technical solution, a through hole is provided on the base plate, and the lamp holder can be detachably installed on the connecting frame through the through hole.

[0013] As a further improvement to the above technical solution, a lampshade is also included, which can be detachably installed on the lamp holder through the through hole.

[0014] As a further improvement to the above technical solution, the base plate is provided with baffles spaced circumferentially at the opening of the through hole facing the installation space, and the lampshade can be moved to abut against the baffles.

[0015] As a further improvement to the above technical solution, a first connector is provided on the lampshade, and the first connector passes through the lampshade and connects to the lamp holder.

[0016] As a further improvement to the above technical solution, the lamp holder is provided with a connecting part for the first connecting member to connect, and there is a gap between the connecting part and the connecting frame.

[0017] As a further improvement to the above technical solution, each of the uprights includes a plurality of support rods arranged in the front-to-back direction, and the shelf is connected to the plurality of support rods of the same upright on one side in the left-to-right direction.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] The main function of food warming equipment is to place prepared food on a tray and then on a warming rack to maintain a certain temperature and preserve its texture. The principle is based on the heating of light bulbs and the focusing of light through the lampshade, which illuminates the food to achieve a warming effect. The food warming rack has multiple layers, each with light bulbs installed at designed intervals to ensure even heating of the food. However, existing racks have the light bulbs directly mounted on the outer steel plate. This makes reassembly difficult if the light bulbs and related electrical components are removed during packaging and transportation. If the light bulbs and components are not removed, the racks will protrude at the bulb locations, preventing horizontal stacking and requiring wrapping with lightweight materials like foam, increasing the overall packaging space and significantly raising transportation costs. Therefore, this application provides a food warming device that reduces transportation costs and is easy for users to assemble.

[0030] Reference Figure 1 and Figure 2 This application provides a food warming device, which includes a stand 1 and a shelf 2. There are two stands 1, which are respectively arranged on the left and right sides. There are at least two shelves 2 arranged from top to bottom. The shelves 2 are detachably connected to the two stands 1 on the left and right sides respectively. The projections of the shelves 2 and the stands 1 on any vertical plane and any horizontal plane are rectangular. The upper side of the lower shelf 2 is a support platform. The upper shelf 2 is provided with a set of 31 heat-preserving lamps 31. The emission end of the heat-preserving lamps 31 extends through the lower side of the upper shelf 2. The bottom of the upper shelf 2 is provided with a clearance cavity 201. The bottom height of the emission end of the heat-preserving lamps 31 is greater than the height of the lower side of the upper shelf 2.

[0031] When stacking shelf 2, the heat insulation lamp 31 group 3 can be completely hidden inside the clearance cavity 201. When disassembling and assembling the upright frame 1 and shelf 2 for packaging and transportation, when stacking the upright frame 1 and shelf 2, whether the upright frame 1 is placed on the side of the bearing platform or the side of the clearance cavity 201, the upright frame 1 can abut against the flat outer wall of the shelf 2, so that the stacked upright frame 1 and shelf 2 remain relatively parallel. When stacking shelf 2 between shelf 2, the side of one shelf 2 that serves as the bearing platform or has the clearance cavity 201 and the side of the other shelf 2 that has the clearance cavity 201 or serves as the bearing platform can abut flatly, so that the stacked two shelf 2 remain relatively parallel.

[0032] As can be seen from the above, when packaging and transporting food insulation equipment, the upright frame 1 and the shelf 2 are first disassembled and separated, and then the shelf 2 and the upright frame 1 are packed and stacked. Because the heat preservation lamps 31 groups 3 in the shelf 2 are hidden in the recessed cavity 201, if the upper shelf is stacked elsewhere, it will only abut against the edge of the shelf 2 in the recessed cavity 201, so that the shelf 2 can be placed horizontally. The top of the shelf 2 is a flat bearing platform. At this time, whether the shelf 2 is stacked with each other or the shelf 2 and the upright frame 1 are packed and stacked, the rectangular shelf 2 and the upright frame 1 can be placed flat without protrusion, which greatly reduces the space required for packaging and saves transportation costs.

[0033] Furthermore, the overall width of the stand 1 is equal to the width of the shelf 2. This equal width means that when the stand 1 and shelf 2 are stacked, the packaging box only needs to be designed with one width. There is no need to wrap the stand 1 or shelf 2 of different widths with cushioning materials such as foam, which reduces packaging costs. The length of the stand 1 can be customized according to the number of shelves 2 required by the customer, so that the height difference between the shelves 2 can meet the needs of the food to be placed.

[0034] Reference Figure 2 and Figure 3 The shelf 2 includes an outer frame 21 and a base plate 22 connected to each other, forming an installation space between the outer frame 21 and the base plate 22. In some embodiments, the food warming shelf 2 includes multiple shelves 2 arranged at intervals along the vertical direction. Each shelf 2 uses its upward-facing side as a support platform. Each shelf 2 is equipped with a set of 31 heat-insulating lamps 31. Each shelf 2 has a recessed cavity 201 on its downward-facing side, and the output end of each set of 31 heat-insulating lamps 31 is located within the recessed cavity 201. Each shelf 2 is equipped with insulation cotton 8, which is located between the connecting frame 33 and the outer frame 21. The insulation cotton 8 forms a heat insulation layer, which insulates the heat from the heat lamp 31 group 3 in the upper shelf 2 from the heat lamp 31 group 3 in the lower shelf 2, which serves as a support platform, preventing the lower heat lamp 31 group 3 from overheating. At the same time, the insulation cotton 8 in the two adjacent shelves 2 can form a heat insulation space, reducing the heat loss from the heat lamp 31 in the upper shelf 2.

[0035] Furthermore, the base plate 22 is rectangular in shape, and the recessed cavity 201 is integrally formed by the base plate 22 being recessed towards the outer frame 21. The base plate 22 and the outer frame 21 are fixedly connected by bolts. In this embodiment, multiple sets of heat-insulating lamps 31 are arranged at intervals along the left and right directions on the base plate 22. Specifically, the number of heat-insulating lamps 31 are set on the base plate 22 at each level is calculated according to customer needs and the heating power of the heat-insulating lamps 31. This is to obtain the optimal heating power.

[0036] Reference Figure 3 and Figure 4 The heat-insulating lamp group 31 includes a heat-insulating lamp 31, a lamp holder 32, and a connecting frame 33. The heat-insulating lamp 31, the connecting frame 33, and the lamp holder 32 are all located within the installation space. The connecting frame 33 is connected to the base plate 22 and extends along the base plate 22 toward the outer frame 21. The lamp holder 32 is connected to the connecting frame 33. The heat-insulating lamp 31 is electrically connected to the lamp holder 32. It is only necessary to ensure that the height of the heat-insulating lamp 31 after it is electrically connected to the lamp holder 32 is higher than the height of the bottom of the shelf 2.

[0037] As can be seen from the above, a connecting bracket 33 is set inside the lamp holder to provide a foundation for the installation of the lamp holder 32. Since the lamp holder 32 has a certain length, the connecting bracket 33 extends along the base plate 22 towards the outer frame 21, so that the lamp holder 32 is completely hidden inside the shelf 2 after installation, thus preventing the lamp holder 32 from protruding outside the shelf 2 and causing a bulge when the shelf 2 is packed and stacked.

[0038] In some embodiments, the connecting frame 33 includes a crossbeam 331 and legs 332 connected to each other. The crossbeam 331 is connected to a set of legs 332 in the left and right directions respectively. The crossbeam 331 extends horizontally. The end of the legs 332 away from the crossbeam 331 extends downward and is connected to the base frame. The lamp holder 32 is connected to the crossbeam 331 and is located between the two sets of legs 332. A connecting space is formed between the two sets of legs 332, thereby providing space for the lamp holder 32 to be installed. In this embodiment, the legs 332 are threaded to the base plate 22 by bolts. The bolts are inserted from the side of the base plate 22 away from the outer frame 21 and threaded to the legs 332 to prevent the sharp end of the bolt from injuring the user.

[0039] Specifically, each group includes at least two legs 332. The two legs 332 in the same group form a mounting groove 333 that matches the outer wall of the lamp holder 32. When installing the lamp holder 32, the lamp holder 32 is snapped into the mounting groove 333 of the connecting frame 33, and the lamp holder 32 is slid along the mounting groove 333 until the lamp holder 32 is completely snapped into the bottom of the mounting groove 333. At this time, the mounting groove 333 temporarily fixes the lamp holder 32, making it convenient for the user to completely position the lamp holder 32 on the connecting frame 33 in subsequent processes.

[0040] In some embodiments, the base plate 22 has a through hole 4, and the lamp holder 32 can be detachably installed on the connecting frame 33 through the through hole 4. The food warming device also includes a lamp cover 34. The base plate 22 has a through hole 4, and the lamp cover 34 can be detachably installed on the lamp holder 32 through the through hole 4. Specifically, the through hole 4 includes a first hole 41 and a second hole 42, which are interconnected. The second hole 42 is connected to the first hole 41 on both sides in the left and right directions. The lamp cover 34 passes through the base plate 22 through the second hole 42. The lamp cover 34 is provided with through holes corresponding to each of the first holes 41. The electrical connection end of the lamp holder 32 passes through the first hole 41 and the through hole in sequence and then enters the lamp cover 34. The lamp cover 34 is provided with a first connector 5, which passes through the lamp cover 34 and is connected to the lamp holder 32. The lamp holder 32 is provided with a second connector 6, which passes through the lamp holder 32 and is connected to the connecting frame 33.

[0041] Specifically, in this application, both the first connector 5 and the second connector 6 are connecting bolts.

[0042] As described above, during installation, the lamp holder 32 is first slid into place on the mounting groove 333, so that the lamp holder 32 and the connecting bracket 33 are temporarily positioned relative to each other. Then, the support legs 332 of the connecting bracket 33 are fixed to the base plate 22 with bolts. After that, the lamp holder 32 and the connecting bracket 33 are connected using the second connector 6. Finally, the lamp cover 34 is installed on the base plate 22 after passing through the second hole 42. At this time, the electrical connection end of the lamp holder 32 passes through the first hole 41 and the through hole in sequence and enters the lamp cover 34. Then, the first connector 5 is threaded through the lamp cover 34 and connected to the lamp holder 32. Finally, the heat insulation lamp 31 is connected to the electrical connection end of the lamp holder 32, thereby completing the connection between the heat insulation lamp 31 base and the base plate 22.

[0043] As a further embodiment, the base plate 22 is provided with baffles 7 at intervals along the circumference at the opening of the through hole 4 facing the installation space. The lampshade 34 can be moved to abut against the baffles 7. When the lampshade 34 is passed through the through hole 4, the circumferentially arranged baffles 7 can form a locking position on the lampshade 34, thereby fixing the lampshade 34 on the base plate 22 in conjunction with the first connector 5.

[0044] As a further embodiment, the lamp holder 32 is provided with a connecting part 321 for the first connecting member 5 to be connected. There is a gap between the connecting part 321 and the connecting frame 33. After the lamp cover 34 is installed on the base plate 22, the first connecting member 5 is screwed in. The threaded end of the first connecting member 5 passes through the connecting part 321. At this time, the threaded end of the first connecting member 5 enters the gap between the connecting part 321 and the connecting frame 33, which provides a buffer and space for the first connecting member 5 to be connected to the connecting part 321, avoiding the risk that the first connecting member 5 and the connecting frame 33 will not be able to be fixed.

[0045] Each upright 1 includes multiple support rods 11 arranged in the front-to-back direction. The shelf 2 is connected to multiple support rods 11 of the same upright 1 on one side in the left-to-right direction. Furthermore, in this application, the same upright 1 includes two support rods 11 and at least one crossbar 12. The crossbar 12 extends in the front-to-back direction, and multiple support rods 11 are connected to the crossbar 12. The crossbar 12 is located at the bottom of each support rod 11. When the food warming equipment is assembled, the crossbar 12 can be directly placed on the platform where the food warming equipment is located, thereby increasing the contact area between the entire food warming equipment and the platform.

[0046] Furthermore, the support rod 11 and the crossbar 12 are integrally formed to improve the connection strength between them, and the length of the crossbar 12 is equal to the width of the shelf 2.

[0047] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
