The steam pipes 140 are connected to the warming box assembly 114, and the steam assembly 130 connects the base frame 111 and the steam pipes 140.

[0037] This embodiment is a drawer-type warming cabinet 100 for multi-layer insulated food. For example, the warming cabinet assembly 114 has three layers of warming cabinets: a first warming cabinet 114A, a second warming cabinet 114B, and a third warming cabinet 114C. The second warming cabinet 114B is located between the first warming cabinet 114A and the third warming cabinet 114C, so that the cabinet 110 has three layers of warming cabinets. The number of linkage mechanisms 120 and the number of steam pipes 140 can be the same as the number of warming cabinets.

[0038] The rear assembly 112 may include a first side plate 1122, a second side plate 1124, a first bottom plate 1126A, a second bottom plate 1126B, and a third bottom plate 1126C, as well as three frames 1128. Each of the three frames 1128 is rectangular and has an opening 112A. The three frames 1128 are respectively located on the rear side of the first insulation box 114A, the second insulation box 114B, and the third insulation box 114C. The two sides of the three frames 1128 are respectively connected to the first side plate 1122 and the second side plate 1124, and the bottom sides of the three frames 1128 are respectively connected to the corresponding first bottom plate 1126A, second bottom plate 1126B, and third bottom plate 1126C.

[0039] These three linkage mechanisms 120 are movably disposed in the first insulation box 114A, the second insulation box 114B, and the third insulation box 114C of the insulation box assembly 114, respectively; these three steam pipes 140 are also respectively connected to the first insulation box 114A, the second insulation box 114B, and the third insulation box 114C of the insulation box assembly 114. Therefore, each of the first insulation box 114A, the second insulation box 114B, and the third insulation box 114C is provided with one linkage mechanism 120 and one steam pipe 140. In one embodiment, these steam pipes 140 are respectively disposed in corresponding frames 1128.

[0040] These three linkage mechanisms 120 respectively include a drawer tray 122, a door assembly 124, two connecting rods 126, and a rear door 128. The drawer tray 122 is located between the door assembly 124 and the rear door 128. The door assembly 124 serves as the opening element on the front side of the drawer-type warming cabinet 100, and the rear door 128 serves as the opening element on the rear side of the drawer-type warming cabinet 100. The size of the rear door 128 is approximately the same as the size of the opening 112A of the frame 1128. The rear door 128 is located at the opening 112A and can be pivotally connected to the corresponding frame 1128, so that the rear door 128 can be opened or closed relative to the frame 1128 to expose or cover the opening 112A, allowing users (such as shop owners) to replenish goods from the rear of the drawer-type warming cabinet 100.

[0041] Link 126 connects the drawer tray 122 and the door assembly 124.

Figure 7 This is a schematic diagram showing the drawer support plate in the pulled-out position and the rear door open from another perspective, according to the present invention. Please refer to... Figures 1 to 7 The linkage mechanism 120 of this utility model includes a main body 121, a drawer tray 122, at least one movable structure 123, a door assembly 124, two connecting rods 126, at least one merchandise tray 125, a buffer structure 127, a rear door 128, and a heat-insulating heating element 129. The number of movable structures 123 and merchandise trays 125 can be adjusted according to actual conditions. Movable structures 123 are connected to both sides of the main body 121. The heat-insulating heating element 129 is disposed on the main body 121. The heat-insulating heating element 129 is, for example, a heat-insulating heating body, which may contain a heat pipe, heating wire, or heating tube for heating or heat preservation. The three main bodies 121 and their connected movable structures 123 can be positioned such that… Figure 3 Within the first insulated box 114A, the second insulated box 114B, and the third insulated box 114C shown in the diagram, a drawer tray 122 is movably connected to the main body 121. A food tray 125 is disposed on the drawer tray 122 and can hold food. A heat source is provided to the food tray 125 on the drawer tray 122 by a heat-insulating heating element 129. The two inner sides of the drawer tray 122 are respectively movable relative to the moving structure 123, so that the drawer tray 122 can move relative to the main body 121. The moving structure 123 can be a slide rail, a slide groove, or other element with a linear moving mechanism, all of which are equivalent replacements of the elements in this utility model.

[0044] The rear side of the main body 121 can be connected to the frame 1128, such as... Figure 7 As shown, the rear hinged door 128 can be pivotally connected below the opening 112A of the frame 1128, so that the rear hinged door 128 can be opened or closed relative to the frame 1128 (e.g., Figure 2(As shown). In one embodiment, in as... Figure 3 A buffer structure 127 is provided within the first insulated box 114A, the second insulated box 114B, and the third insulated box 114C of the insulated box assembly 114 shown. The buffer structure 127 is located on the rear side of the main body 121. For example, the buffer structure 127 can be located between the main body 121 and the frame 1128. When the drawer tray 122 moves relative to the main body 121, the buffer structure 127 can reduce the impact of the drawer tray 122 retracting to its original position. Figure 4A The collision of the storage position PA1. The buffer structure 127 of this utility model, for example, uses elements such as gaskets and dampers that have a buffering effect, which are all elements that can be equivalently replaced by this utility model.

[0045] The hinged door assembly 124 includes a frame 1242, a hinged door 1244, and a pivot structure 1246. The bottom side of the frame 1242 is connected to the front side of the main body 121, and the top end of the frame 1242 is connected to the pivot structure 1246. One end of the hinged door 1244 is pivotally connected to the pivot structure 1246, allowing the hinged door 1244 to rotate relative to the frame 1242. In one embodiment, the hinged door 1244 may be a glass structure. The hinged door 1244 may be a transparent structure, allowing the user to view the food inside the insulated box assembly 114 through the hinged door 1244 without opening it. The first ends 126A of the two connecting rods 126 are pivotally connected to the two sides of the drawer support plate 122, while the second ends 126B of the two connecting rods 126 are pivotally connected to the hinged door 1244. That is, one end of the hinged door 1244 is pivotally connected to the pivot structure 1246 on the door frame 1242, and the other end of the hinged door 1244 is pivotally connected to the second ends 126B of the two connecting rods 126, forming a linkage structure of the hinged door 1244, the connecting rods 126, and the drawer support plate 122.

[0046] In this linkage structure configuration of the drawer support 122 and the hinged door assembly 124, the hinged door assembly 124 is in a position as follows: Figure 4A or Figure 5A When the drawer trays 122 are in the closed position PB1 and the drawer trays 122 are in the retracted position PA1, these drawer trays 122 can be respectively positioned as shown in the diagram. Figure 3 Within the first insulated box 114A, the second insulated box 114B, and the third insulated box 114C shown in the diagram, the heat-insulating heating element 129 is located below the drawer tray 122. The heat source provided by the heat-insulating heating element 129 heats the merchandise tray 125 on the drawer tray 122. When the drawer tray 122 is pulled out, as... Figures 5A to 5B As the drawer support 122 moves along a pull-out direction LA, it drives the connecting rod 126 to rotate the hinged door 1244 in the hinged door assembly 124 outward around a rotation direction RA, thus opening the door. Figure 5BThe diagram shows the drawer support 122 being pulled out to a specific position PA3, causing the hinged door assembly 124 to rotate to a specific position PB3. As the drawer support 122 continues to be pulled out, it drives the connecting rod 126 to rotate, thereby causing the hinged door 1244 to continue rotating until the drawer support 122 is fully pulled out. Figure 4C and Figure 5C The door assembly 124 shown is in the open position PB2, and the drawer tray 122 is moved away to expose the heat-insulating heating element 129 (e.g., Figure 4C When the drawer tray 122 is in the pulled-out position PA2 (as shown), the lifting door 1244 will slightly press down on the second end 126B of the connecting rod 126 due to the rotation radius. This causes the first end 126A of the connecting rod 126 to be slightly outward (towards the pull-out direction LA) and locked, preventing the drawer tray 122 from retracting and thus fixing its position. Figure 6 and Figure 7 As shown, the drawer tray 122 is in the pulled-out position PA2, and the door assembly 124 is in the open position PB2, allowing users to more easily pull and retrieve the desired items from the product tray 125. In one embodiment, the rear door 128 can be opened, allowing users (such as shopkeepers) to replenish goods from the rear of the drawer-type warming cabinet 100.

[0047] When the drawer tray 122 is pushed back, it drives the connecting rod 126 to push inward, which in turn causes the lifting door 1244 in the lifting door assembly 124 to rotate inward (meaning it rotates in a direction opposite to the rotation direction RA), thus closing the cover (as shown). Figures 5C to 5B (As shown in the process), the drawer tray 122 is pushed back halfway (as shown in the process). Figure 5B When the drawer door 1244 is opened (as shown), the weight of the door (due to gravity) will cause the drawer tray 122 to automatically push back as shown. Figure 5A The drawer tray 122 is shown in storage position PA1 (or initial position, original position); when the drawer tray 122 is retracted to storage position PA1, the door 1244 is just closed. During this process, the present invention can reduce the collision when the drawer tray 122 retracts (meaning it moves in the opposite direction to the pull-out direction LA) by setting a buffer structure 127 at the rear end of the drawer tray 122.

[0048] Figure 8 This is a schematic diagram of the steam water pan being pulled out according to this utility model. Figure 9 This is a side view of the steam water pan being withdrawn according to this utility model. Please refer to [link / reference]. Figure 8 and Figure 9As shown, the drawer-type warming cabinet 100 of this utility model can provide steam to maintain the relative humidity of the goods inside the first warming cabinet 114A, the second warming cabinet 114B, and the third warming cabinet 114C in the warming cabinet assembly 114. Each of the first warming cabinets 114A, 114B, and 114C is controlled by a hygrometer, and steam is released by controlling the water valve according to a set setting. Each of the first warming cabinets 114A, 114B, and 114C provides lighting and heating / heating control. In other words, each of the first warming cabinets 114A, 114B, and 114C has its own independent control switch, allowing for use as needed. For example, temperature and humidity settings, or lighting, can be turned on or off as required.

[0049] Taking this embodiment as an example, the base frame 111 includes a housing 111A, a heating plate 111B, a switching element 111C, a first-layer regulating element 111D, a second-layer regulating element 111E, and a third-layer regulating element 111F. The steam assembly 130 includes a front cover 131, a steam cover 132, a steam water pan 134, a pipeline PA, and a solenoid valve PB. The solenoid valve PB connects the pipeline PA and the steam pipeline 140, and can open or close the connection between the pipeline PA and the steam pipeline 140 to open or close whether the steam pipeline 140 provides steam. In other embodiments, the steam pipeline 140 may also have a water valve switch. The heating plate 111B is disposed within the housing 111A, wherein the heating plate 111B is any type of heating element that provides a heat source to the steam water pan 134. Switch element 111C is the power switch for turning the entire drawer-type warming cabinet 100 on or off. The first-layer control element 111D, the second-layer control element 111E, and the third-layer control element 111F are independent control switches for the first warming chamber 114A, the second warming chamber 114B, and the third warming chamber 114C, respectively, allowing for the setting of temperature and humidity or the use of lighting as needed. In this embodiment, the front cover 131 can cover the switch element 111C, the first-layer control element 111D, the second-layer control element 111E, the third-layer control element 111F, and the steam water tray 134. The steam water tray 134 is accommodated in the space DA within the housing 111A, and the steam cover 132 connects to the pipe PA, which in turn connects to the steam pipe 140. Thus, the steam cover 132 on the steam water tray 134 connects the pipe PA and the steam pipe 140. When the steam water tray 134 is heated by the heating plate 111B below, steam is sent along the pipe PA and the steam pipe 140 to the first insulation box 114A, the second insulation box 114B, and the third insulation box 114C on each layer for humidification. Furthermore, when the steam cover 132 is opened, the steam water tray 134 can be removed for easy cleaning, allowing it to be reused.

[0050] Furthermore, because the insulation, humidity, and lighting of each layer of the insulated box are independently controlled, it can be customized to meet specific needs. Figure 10 The options are a double-layer drawer-type warming cabinet (200) or a single-layer drawer-type warming cabinet (300).

[0051] In summary, this utility model, through the linkage mechanism of the drawer tray and the lifting door assembly, makes it easier for users to pull and grab the desired items.

[0052] Furthermore, each layer of the insulation box in this invention has its own independent control switch, so it can be used as needed. For example, the temperature and humidity settings, or the use of lighting, can be turned on or off as needed, and the number of insulation boxes can be adjusted as required.

[0053] In addition, this utility model reduces the impact when the drawer tray is retracted into its storage position by means of a buffer device.

[0054] In addition, the drawer-type warming cabinet of this utility model can be equipped with a rear lifting door, which allows users (such as shop owners) to replenish goods from the rear of the drawer-type warming cabinet.

[0055] Although the present invention has been disclosed above by the embodiments described above, it is not intended to limit the present invention. Any person skilled in the art should be able to make some modifications and refinements without departing from the spirit and scope of the present invention, and all such modifications and refinements shall fall within the protection scope of the present invention.
