Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation cabinets, in particular to a baking display cabinet. Background Art

[0002] Deli food display cabinets are used as props for displaying prepared food. Their use makes hot spots and promotional products more prominent in the store. They also create a respectful, trustful, civilized, and hygienic shopping environment, shortening the distance between the store and customers and encouraging their purchase desire.

[0003] Delicatessen display cases on the market can be categorized as room temperature, heated, or refrigerated. All of these types can slow the growth of bacteria within food, extending its shelf life. Delicatessen display cases are commonly used in fresh produce areas such as the bakery, prepared food, and mixed vegetable sections of supermarkets and shopping malls, and are a popular choice for many major supermarkets both domestically and internationally.

[0004] Traditional food warming display cabinets offer limited functionality, often using heat radiation devices for baking. A rotating mechanism typically rotates the food around the heat source. Due to the laws of heat movement, the bottom of the food warming display cabinet is relatively cool, leading to uneven heating of the food. This uneven heating also requires longer heating times, reducing heating efficiency. Utility Model Content

[0005] The utility model provides a baking display cabinet that solves the problem of existing baking methods using heat radiation devices, which usually rotate the food around the heat source. Due to the laws of heat movement, the bottom temperature of the food display cabinet is relatively low and tends to be cool, resulting in uneven heating of the food. Due to the uneven heating of the food, the food needs to be heated for a longer time, which reduces the heating efficiency.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A bottom box is provided under the cabinet, a first ventilation hole is opened in the circumference of the bottom of the cabinet, a second ventilation hole is opened on the top of the cabinet, an air inlet and an air outlet are opened at the bottom of the cabinet, a first heating element is arranged in the cabinet, a circulation device, a cooling device and a driving device are all arranged in the bottom box, and the driving device is arranged at the bottom of the cabinet, a rotating structure is arranged in the cabinet, and the bottom of the rotating structure passes through the bottom of the cabinet and is connected to the driving device.

[0008] The beneficial effects of the present invention are as follows: a first heating element is disposed within the cabinet body, and the food within the cabinet body is heated by the first heating element. A circulation device is also disposed at the bottom of the cabinet body, and the circulation device circulates the heat within the cabinet body, thereby evenly distributing the heat within the cabinet body. The rotating structure drives the food within the cabinet body to rotate, thereby heating the food more evenly. This reduces the heating time of the food and increases the baking efficiency of the food. The heat outside the cabinet body is dissipated into the air through the first and second ventilation holes, preventing the cabinet body from being damaged by excessive temperature inside the cabinet body.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the cabinet body has a cabinet door, which is movably connected to the cabinet body. The cabinet door is provided with a sealing device and a pulling member. The sides of the cabinet door and the cabinet body are transparent panels, which are installed on the sides of the cabinet body through columns. The transparent panels on each side of the cabinet body are provided with multiple layers. The first ventilation hole and the second ventilation hole are respectively located in the upper and lower parts between the two layers of transparent panels, and the columns are provided with a heat insulation coating.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, by providing a cabinet door on the cabinet body, it is convenient for users to remove food from the cabinet body. By installing transparent panels around the cabinet body, the types and quantities of food inside the cabinet body can be more clearly displayed, making it easier for buyers to choose and for users to replace and add new food. Heat outside the cabinet body is dissipated into the air through the first ventilation hole, the second ventilation hole, and the gap between the two layers of transparent panels, preventing the cabinet body from being damaged by excessive temperature inside the cabinet body. In addition, by providing a thermal insulation coating on the columns to reduce the temperature, the possibility of high temperature in the cabinet body is reduced, thereby improving safety.

[0012] Furthermore, the rotating structure includes a first connecting shaft, a second connecting shaft, a third connecting shaft, a cargo tray and a cargo rack. The top of the first connecting shaft passes through the top of the cabinet and is rotatably arranged on the top of the cabinet through a bearing. The bottom of the first connecting shaft passes through the cargo tray and is connected to the top of the second connecting shaft. The second connecting shaft is connected to the output end of the driving device through the third connecting shaft. The cargo tray has multiple sides, and the cargo rack can be detachably hung on any side of the cargo tray. The cargo rack is provided with multiple layers.

[0013] The beneficial effect of adopting the above further solution is that the first connecting shaft, the second connecting shaft, and the third connecting shaft are connected in sections to form a support column for supporting the pallet and the pallet rack, making the entire column easy to disassemble or replace, and also easy to replace or disassemble the pallet. At the same time, the pallet rack is made detachable, making it convenient for users to hang it as needed.

[0014] Furthermore, the rotating structure includes a pallet, a supporting rack and a connecting column. The bottom of the connecting column is rotatably connected to the output end of the driving device. A multi-layer supporting rack is arranged on the connecting column. There are multiple pallets, and multiple pallets are placed on multiple supporting racks.

[0015] The beneficial effect of adopting the above further solution is that the bottom of the connecting column is driven to rotate by the output end of the driving device, so that the connecting column drives the multi-layer tray to rotate together, so that the food on the multi-layer tray can be baked by rotation, ensuring the uniformity of food baking.

[0016] Furthermore, the rotating structure is provided with one or more groups, and the one or more groups of rotating structures are all provided in the cabinet.

[0017] The beneficial effect of adopting the above further solution is that one or more groups of rotating structures can be made in the same cabinet as needed, which can increase the number of exhibits while saving production costs.

[0018] Furthermore, the circulation device includes a first fan, a second heating element and an air duct. The first fan and the second heating element are arranged in the air duct. The air outlet of the first fan faces the second heating element, and the air inlet and the air outlet are connected to the air duct.

[0019] The beneficial effect of adopting the above further solution is that the air inlet and the air outlet are connected to the air duct, and the first fan blows the heat generated by the second heating element into the cabinet through the air duct, so that heat is generated in the cabinet. The air inlet and the air outlet form a circulation system with the air duct, so that the heat in the cabinet is circulated. This makes the heat in the cabinet more uniform, and the baked food is heated more evenly, while reducing baking time and increasing baking efficiency.

[0020] Furthermore, the first heating element is arranged in the middle of the cabinet and is located at the first connecting axis. There is at least one or multiple first heating elements, and the multiple first heating elements are arranged around the second connecting axis.

[0021] The beneficial effect of adopting the above further solution is that the first heating element is arranged in the middle of the cabinet, which increases the temperature inside the cabinet, makes the first heating element closer to the food, and reduces the baking time of the food.

[0022] Furthermore, the first heating element is arranged on the side of the cabinet, and there is at least one or multiple first heating elements, and the multiple first heating elements are respectively arranged on multiple sides of the cabinet.

[0023] The beneficial effect of adopting the above further solution is that the first heating element is arranged on the side of the cabinet, which increases the temperature inside the cabinet, makes the temperature distribution inside the cabinet uniform, and makes the baked food more uniform.

[0024] Furthermore, the cooling device includes a second fan and a cooling air duct, the air outlet of the second fan is connected to the lower part of the cooling air duct, and the upper part of the cooling air duct is connected to the first ventilation hole.

[0025] The beneficial effect of adopting this further solution is that the second fan blows cool air into the cooling air duct, which is then blown out through the first vents between the transparent panels of the cabinet. Heat outside the cabinet is dissipated into the air through the first vents, the second vents, and the gap between the two transparent panels, cooling the transparent panels outside the cabinet and preventing damage to the cabinet due to excessive temperatures inside the cabinet.

[0026] Furthermore, the control device includes a controller, a first sensor, and a second sensor. The controller is arranged on the bottom box, the first sensor is arranged at the bottom of the cabinet, and the second sensor is arranged inside the cabinet and close to the cabinet door. The controller is electrically connected to the circulation device, the first heating element, the cooling device, the driving device, the first sensor and the second sensor.

[0027] The beneficial effect of adopting the above further solution is that the first sensor is installed at the bottom of the cabinet, which reduces the impact of high temperature on the operation of the first sensor. At the same time, it also reduces the wiring of the first sensor in the longitudinal direction of the cabinet, reducing the impact of high temperature on the wiring. It can achieve the effect of baking different foods at the same time, and keeping them warm after baking. The second sensor is set near the cabinet door to detect the switch of the cabinet door. After detecting that the cabinet door is open, the drive device stops rotating, and the heating and the first fan are stopped from blowing air to the second heating element at the same time. At the same time, the controller is electrically connected to the circulation device, the cooling device, the drive device, the first sensor and the second sensor. The operation of the circulation device, the first heating element, the cooling device, the drive device, the first sensor and the second sensor can be controlled by manually operating the controller, thereby forming manual control of the temperature inside the cabinet.

[0044] like Figure 1-10 As shown, the cabinet body 200 has a cabinet door 210, which is movably connected to the cabinet body 200. A sealing device and a pulling member 213 are provided on the cabinet door 210. The sides of the cabinet door 210 and the cabinet body 200 are both transparent panels 250. The transparent panels 250 are installed on the sides of the cabinet body 200 through columns 240. The transparent panels 250 on each side of the cabinet body 200 are provided with multiple layers. The first ventilation hole 220 and the second ventilation hole 230 are respectively located at the upper and lower parts between the two layers of transparent panels 250, and the columns 240 are provided with a heat insulation coating.

[0045] Specifically, in this embodiment, the cabinet door 210 is pivotally connected to the cabinet body 200 via a hinge. The cabinet door 210 can be opened sideways or vertically. When the cabinet door 210 is closed, a sealing device seals the cabinet door 210 and the cabinet body 200, preventing high-temperature leakage from the cabinet body 200. In this embodiment, the transparent panel 250 is triple-layered glass. In this embodiment, the first ventilation hole 220 and the second ventilation hole 230 are located between the single-layered glass and the double-layered glass. The cooling device 600 cools the single-layered glass.

[0046] like Figure 1-10As shown, the rotating structure 700 includes a first connecting shaft 710, a second connecting shaft 720, a third connecting shaft 730, a pallet 740 and a pallet rack 750. The top of the first connecting shaft 710 passes through the top of the cabinet 200 and is rotatably set on the top of the cabinet 200 through the bearing joint 711. The bottom of the first connecting shaft 710 passes through the pallet 740 and is connected to the top of the second connecting shaft 720. The second connecting shaft 720 is connected to the output end of the driving device 800 through the third connecting shaft 730. The pallet 740 has multiple sides. The pallet rack 750 can be detachably hung on any side of the pallet 740. The pallet rack 750 is provided with multiple layers.

[0047] Specifically, the top of the first connecting shaft 710 passes through the top of the cabinet 200 and is rotatably arranged on the top of the cabinet 200 through the bearing 711. The bottom of the first connecting shaft 710 passes through the pallet 740 and is connected to the top of the second connecting shaft 720. The second connecting shaft 720 is connected to the output end of the driving device 800 through the third connecting shaft 730. In this embodiment, the segments of the first connecting shaft 710, the second connecting shaft 720 and the third connecting shaft 730 are respectively connected together by threads. The top of the pallet 750 is suspended on the side of the pallet 740. In this embodiment, the pallet 740 has five sides, and each side of the pallet 740 can hang a pallet 750. Alternatively, the pallet 740 is not limited to five sides and can also be set as other multi-sided pallets 740.

[0048] like Figure 1-10 As shown, one or more groups of rotating structures 700 are provided, and one or more groups of rotating structures 700 are all provided in the cabinet 200 .

[0049] Specifically, a set of rotating structures 700 is provided in a cabinet 200 for centrally baking foods on the trays 750 .

[0050] like Figure 1-10 As shown, the circulation device 400 includes a first fan 410, a second heating element 420 and an air duct 430. The first fan 410 and the second heating element 420 are arranged in the air duct 430, the air outlet of the first fan 410 faces the second heating element 420, and the air inlet 260 and the air outlet 270 are connected to the air duct 430.

[0051] Specifically, the first fan 410 blows the heat generated by the second heating element 420 in the air duct 430 into the cabinet 200 through the air inlet 260, and the heat in the cabinet 200 returns to the air duct 430 through the air outlet 270, forming a circulation system to circulate the heat in the cabinet 200.

[0052] like Figure 1-10As shown, the first heating element 500 is arranged in the middle of the cabinet 200 and is located at the first connecting shaft 710. There is at least one or multiple first heating elements 500, and multiple first heating elements 500 are arranged around the second connecting shaft 720.

[0053] Specifically, the first heating element 500 is disposed in the middle of the cabinet 200, thereby increasing the temperature inside the cabinet 200. In this embodiment, there are two first heating elements 500, which are disposed around the third connecting shaft 730, and the bottom of the first heating element 500 is fixed to the bottom of the cabinet 200.

[0054] like Figure 1-10 As shown, the cooling device 600 includes a second fan 610 and a cooling air duct 620 , the air outlet of the second fan 610 is connected to the lower part of the cooling air duct 620 , and the upper part of the cooling air duct 620 is connected to the first ventilation hole 220 .

[0055] Specifically, the second fan 610 blows cool air into the cooling air duct 620, which is then blown out through the first vents 220 into the space between the transparent panels 250 of the cabinet 200. Heat outside the cabinet 200 is dissipated into the air through the first vents 220, the second vents 230, and the gaps between the two layers of transparent panels 250, thereby cooling the transparent panels 250 outside the cabinet 200 and preventing damage to the cabinet 200 caused by excessive temperatures inside the cabinet 200. In this embodiment, the transparent panels 250 are triple-layered transparent glass, and the first vents 220 and the second vents 230 are located between the single-layer glass and the double-layer glass.

[0056] like Figure 1-10 As shown, the control device 900 includes a controller, a first sensor, and a second sensor. The controller is arranged on the bottom box 300, the first sensor is arranged at the bottom of the cabinet 200, and the second sensor is arranged inside the cabinet 200 and close to the cabinet door 210. The controller is electrically connected to the circulation device 400, the cooling device 600, the driving device 800, the first sensor and the second sensor.

[0057] Specifically, the first sensor is installed at the bottom of the cabinet 200, and the second sensor is set near the cabinet door 210 to detect the opening and closing of the cabinet door 210. In this embodiment, the first sensor is a temperature sensor, which is used to detect the temperature inside the cabinet 200 and transmit the detected data signal to the controller, and the controller controls the first heating element 500 and the circulation device 400 to heat the cabinet 200. In this embodiment, the second sensor is a door opening detection sensor. Alternatively, the second sensor can also be a travel switch, or other components with the function of detecting a switch. In this embodiment, after the second sensor detects that the cabinet door 210 is opened, it transmits the detected signal data to the controller, and the controller controls the drive device 800 to stop rotating, so that the drive device 800 controls the rotating structure 700 to stop rotating. In this embodiment, the controller, the first sensor, and the second sensor are not shown in the figure.

[0058] The beneficial effects of this embodiment are as follows: a first heating element 500 is provided inside the cabinet 200, and the food inside the cabinet 200 is heated by the first heating element 500. A circulation device 400 is provided at the bottom of the cabinet 200, and the heat inside the cabinet 200 is circulated by the circulation device 400, so that the heat inside the cabinet 200 is evenly distributed. At the same time, the food is driven to rotate inside the cabinet 200 by the rotating structure 700, so that the heating of the food is more even. The heating time of the food is reduced and the baking efficiency of the food is increased. The heat outside the cabinet 200 is dissipated into the air through the first ventilation hole 220 and the second ventilation hole 230, preventing the cabinet 200 from being damaged by the high temperature inside the cabinet 200.

[0059] The operating process of this embodiment is as follows: After the shelf 750 is suspended on the pallet 740, food is placed on the shelf 750. The controller manually or automatically turns on the first heating element 500 and the second heating element 420 for heating. The controller also controls the first fan 410 to blow air toward the second heating element 420, blowing the heat generated by the second heating element 420 into the cabinet 200. The heat within the cabinet 200 forms a circulation system through the air inlet 260 and the air outlet 270, together with the air duct 430, to circulate the heat within the cabinet 200. The first sensor transmits the detected data signal to the controller, which controls the first heating element 500 and the circulation device 400 to heat the cabinet 200. The controller controls the driving device 800 to rotate the third connecting shaft 730, which in turn drives the first connecting shaft 710 and the second connecting shaft 720 to rotate, thereby driving the pallet 740 and the shelf 750 to rotate together.

[0060] When the second sensor detects that the cabinet door 210 is opened, the detected signal data is transmitted to the controller, and the controller controls the driving device 800 to stop rotating, so that the driving device 800 controls the rotating structure 700 to stop rotating.

[0061] Example 2

[0062] Based on Example 1, this embodiment differs from Example 1 in that:

[0063] like Figure 1-10 As shown, the first heating element 500 is disposed on a side surface of the cabinet 200 . There is at least one first heating element 500 or a plurality of first heating elements 500 are disposed.

[0065] The beneficial effects of this embodiment are as follows: a first heating element 500 is provided inside the cabinet 200, and the food inside the cabinet 200 is heated by the first heating element 500. A circulation device 400 is provided at the bottom of the cabinet 200, and the heat inside the cabinet 200 is circulated by the circulation device 400, so that the heat inside the cabinet 200 is evenly distributed. At the same time, the food is driven to rotate inside the cabinet 200 by the rotating structure 700, so that the heating of the food is more even. The heating time of the food is reduced and the baking efficiency of the food is increased. The heat outside the cabinet 200 is dissipated into the air through the first ventilation hole 220 and the second ventilation hole 230, preventing the cabinet 200 from being damaged by the high temperature inside the cabinet 200.

[0066] The operating process of this embodiment is as follows: After the shelf 750 is suspended on the pallet 740, food is placed on the shelf 750. The controller manually or automatically turns on the first heating element 500 and the second heating element 420 for heating. The controller also controls the first fan 410 to blow air toward the second heating element 420, blowing the heat generated by the second heating element 420 into the cabinet 200. The heat within the cabinet 200 forms a circulation system through the air inlet 260 and the air outlet 270, together with the air duct 430, to circulate the heat within the cabinet 200. The first sensor transmits the detected data signal to the controller, which controls the first heating element 500 and the circulation device 400 to heat the cabinet 200. The controller controls the driving device 800 to rotate the third connecting shaft 730, which in turn drives the first connecting shaft 710 and the second connecting shaft 720 to rotate, thereby driving the pallet 740 and the shelf 750 to rotate together.

The first ventilation hole 220 and the second ventilation hole 230 are respectively located at the upper and lower parts between the two layers of transparent panels 250, and the columns 240 are provided with a heat insulation coating.

[0070] Specifically, in this embodiment, the cabinet door 210 is slidably connected to the cabinet body 200, and the cabinet door 210 slides open or closed relative to a side surface of the cabinet body 200. When the cabinet door 210 is closed, a sealing device seals the cabinet door 210 and the cabinet body 200. In this embodiment, the transparent panel 250 is triple-layered glass. In this embodiment, the first ventilation hole 220 and the second ventilation hole 230 are located between the single-layered glass and the double-layered glass. The cooling device 600 cools the single-layered glass.

There are multiple pallets 760, and multiple pallets 760 are placed on multiple supporting racks 750.

[0076] Specifically, in this embodiment, the output end of the driving device 800 drives the bottom of the connecting column 770 to rotate, so that the connecting column 770 drives the multi-layer supporting rack 750 to rotate together, so that the food on the multi-layer supporting rack 750 can be baked by rotation, ensuring the uniformity of food baking.

[0077] The beneficial effects of this embodiment are as follows: a first heating element 500 is provided inside the cabinet 200, and the food inside the cabinet 200 is heated by the first heating element 500. A circulation device 400 is provided at the bottom of the cabinet 200, and the heat inside the cabinet 200 is circulated by the circulation device 400, so that the heat inside the cabinet 200 is evenly distributed. At the same time, the food is driven to rotate inside the cabinet 200 by the rotating structure 700, so that the heating of the food is more even. The heating time of the food is reduced and the baking efficiency of the food is increased. The heat outside the cabinet 200 is dissipated into the air through the first ventilation hole 220 and the second ventilation hole 230, preventing the cabinet 200 from being damaged by the high temperature inside the cabinet 200.

[0078] The operating process of this embodiment is as follows: After the shelf 750 is suspended on the pallet 740, food is placed on the shelf 750. The controller manually or automatically turns on the first heating element 500 and the second heating element 420 for heating. The controller also controls the first fan 410 to blow air toward the second heating element 420, blowing the heat generated by the second heating element 420 into the cabinet 200. The heat within the cabinet 200 forms a circulation system through the air inlet 260 and the air outlet 270, together with the air duct 430, to circulate the heat within the cabinet 200. The first sensor transmits the detected data signal to the controller, which controls the first heating element 500 and the circulation device 400 to heat the cabinet 200. The controller controls the driving device 800 to rotate the third connecting shaft 730, which in turn drives the first connecting shaft 710 and the second connecting shaft 720 to rotate, thereby driving the pallet 740 and the shelf 750 to rotate together.

The heat within the cabinet 200 forms a circulation system through the air inlet 260 and the air outlet 270, together with the air duct 430, to circulate the heat within the cabinet 200. The first sensor transmits the detected data signal to the controller, which controls the first heating element 500 and the circulation device 400 to heat the cabinet 200. The controller controls the driving device 800 to rotate the third connecting shaft 730, which in turn drives the first connecting shaft 710 and the second connecting shaft 720 to rotate, thereby driving the pallet 740 and the shelf 750 to rotate together.
