A constant temperature refrigeration device for snow skin mooncakes

Abstract

This invention relates to the field of refrigeration equipment technology, specifically to a constant-temperature refrigeration device for snow skin mooncakes. By neatly arranging the snow skin mooncakes in various storage components, when retrieving them, the cabinet door is opened, and the handle of one of the storage components is pulled, causing a movable plate to extend outwards. During this extension, the movable plate drives a conveyor belt via friction transmission, causing the mooncakes on the conveyor belt to fall off. This process eliminates the need to open other drawer components or other storage components, greatly reducing heat exchange with the outside. After retrieving the snow skin mooncakes, pressing a button drives the movable plate to move upwards a certain distance within the side panel, releasing the friction transmission between the movable plate and the conveyor belt. Pushing the handle back returns the movable plate and handle to their original positions. At this point, the insulation plate moves forward a certain distance. The insulation plate, in conjunction with the insulation section of the conveyor belt, provides insulation to a certain extent in the vacated area, reducing cooling space, improving work efficiency, and reducing energy consumption.

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a constant temperature refrigeration device for snow skin mooncakes. Background Technology

[0002] Snow skin mooncakes require a unique production and storage process, necessitating low temperatures throughout. Their refrigeration equipment must have a precise temperature control system to maintain a stable 0-5℃ core preservation range, ensuring the crust's soft and chewy texture. However, in scenarios like stores where frequent opening and closing of refrigeration equipment is necessary, this leads to frequent heat exchange between the equipment and the external environment, resulting in reduced refrigeration effectiveness.

[0003] Chinese invention patent application CN 119146676 A discloses a constant temperature and humidity control cabinet. By setting two pull-out mounting plates inside the control cabinet, each mounting plate is equipped with multiple storage mechanisms for storing items. When staff retrieve items, the mounting plates can be pulled out of the control cabinet, at which point the mounting plates can seal the opening of the control cabinet, ensuring that the control cabinet remains closed during the retrieval process, thereby reducing the fluctuation of temperature and humidity inside the control cabinet.

[0004] However, the applicant has found that the prior art has at least the following problems:

[0034] like Figures 1 to 11As shown in the figure, a specific embodiment of the present invention provides a constant temperature refrigeration device for snow skin mooncakes, including a cabinet 101 with a cabinet door 102. The cabinet 101 has a refrigeration chamber 103 inside, and multiple drawer assemblies 201 are installed from top to bottom inside the refrigeration chamber 103. Each drawer assembly 201 includes a tray 202, and multiple storage assemblies 301 are horizontally installed in the tray 202. Each storage assembly 301 includes a housing 302, and a conveyor belt for carrying and conveying mooncakes is provided inside the housing 302. The conveyor belt includes an exchange section 306 and an insulation section 307. An insulation plate 308 is installed at the boundary between the exchange section 306 and the insulation section 307. In the initial state, the insulation plate 308 is located at the rear end of the housing 302. The housing 302 has storage assemblies on both sides for... The air inlet 303, which exchanges cold air, introduces cold air into the gap in the middle of the conveyor belt. Side plates 309 are provided on both sides of the housing 302. A movable plate 312 for pulling outward is provided in the side plate 309. A handle 314 is connected to the end of the movable plate 312. A pull plate 332 is connected between the handle 314 and the housing 302. During the pulling process of the movable plate 312, the conveyor belt is driven to move by friction, and the mooncake is sent out onto the pull plate 332. The movable plate 312 is connected to a button 315 through meshing transmission. The button 315 is installed on the handle 314. When the handle 314 is retracted, pressing the button 315 drives the movable plate 312 to move upward in the side plate 309, so that the friction transmission between the movable plate 312 and the conveyor belt is released.

[0035] In use, the snow skin mooncakes are neatly arranged in each storage component 301. Different fillings of snow skin mooncakes can be placed in different storage components 301. When it is necessary to take out the snow skin mooncakes, open the cabinet door 102, pull the handle 314 of one of the storage components 301, and pull out the moving plate 312. During the pulling out process, the moving plate 312 drives the conveyor belt to move through friction transmission, causing the mooncakes on the conveyor belt to fall. The staff can then catch the mooncakes from below. During this process, there is no need to open other drawer components 201 or other components. The storage component 301 greatly reduces heat exchange with the outside. After the snow skin mooncake is taken out, pressing the button 315 drives the moving plate 312 to move up a certain distance in the side plate 309, so that the friction transmission between the moving plate 312 and the conveyor belt is released. Pushing the handle 314 back makes the moving plate 312 and the handle 314 return to their original positions. At this time, the insulation plate 308 moves forward a certain distance. The insulation plate 308, together with the insulation section 307 of the conveyor belt moving forward, provides a certain degree of insulation for the empty space, which can reduce the cooling space, improve work efficiency, and reduce energy consumption.

[0036] In some optional specific implementations, such as Figures 9 to 11As shown, the handle 314 has two sets of upper and lower guide rails 319 installed inside. A drive rack 320 is adapted to be installed in the upper and lower guide rails 319. The two sets of drive racks 320 are connected to a connecting rod 318. The button 315 is installed on the connecting rod 318. A triangular plate 323 is installed at the bottom of the button 315. The drive rack 320 is meshed with a gear 321. The gear 321 is meshed with a driven rack 322. The driven rack 322 is fixedly installed on the moving plate 312. The button 315 is elastically installed inside the handle 314. A limit component is also installed inside the handle 314 to limit the triangular plate 323 from rebounding when the button 315 is pressed to the bottom. The top of the handle 314 has a relief groove 316 for accommodating the button 315. By pressing button 315, the connecting rod 318 causes the two sets of drive racks 320 to move downward, thereby driving the gear 321 to rotate, and finally driving the moving plate 312 to move upward, detaching from the friction with the conveyor belt, achieving the effect of the moving plate 312 retracting, but the conveyor belt not retracting.

[0037] In some optional specific embodiments, such as Figures 9 to 11 As shown, the limiting component includes a sliding rail 329 fixedly installed inside the handle 314. A movable block 330 is adapted to be installed in the sliding rail 329. The handle 314 has a mounting hole. One end of the movable block 330 extends out of the mounting hole and abuts against the housing 302. The top of the movable block 330 abuts against a top post 328. The top post 328 is connected to a limiting plate 327. The limiting plate 327 is connected to a torsion shaft 326. The torsion shaft 326 is installed on the inner wall inside the handle 314. The movable block 330 has a clearance opening 331 for avoiding the top post 328. A compression spring is connected between the moving block 330 and the inner wall of the handle 314. When the handle 314 is pulled out, the clearance opening 331 is misaligned with the top post 328, the button 315 is pressed down, the triangular plate 323 moves to below the limiting plate 327, and the limiting plate 327 restricts the triangular plate 323 from rebounding. When the handle 314 is pushed back and contacts the housing 302, the compression spring is in a compressed state, the clearance opening 331 is opposite to the top post 328, and under the elastic force of the button 315, the limiting plate 327 loses its limiting effect on the triangular plate 323, the button 315 rebounds, and the moving plate 312 is reset. In this process, by associating the limiting state of the limiting plate 327 on the triangular plate 323 with whether the handle 314 is in contact with the housing 302, it is ensured that after the button 315 is pressed, the limiting state of the triangular plate 323 can only be released when the handle 314 is in contact with the housing 302, thereby resetting the friction transmission action between the moving plate 312 and the conveyor belt, preventing the conveyor belt from retracting, and ensuring that the front end of the conveyor belt always has snow skin mooncakes, and the empty space is always at the heat insulation section 307 at the rear end. It should be noted that the torsion shaft 326 mentioned here is equipped with a torsion spring, which makes it always tend to return to a horizontal state.

[0038] In some optional specific implementations, such as Figures 9 to 11 As shown, the handle 314 has two sets of spring seats 325 installed inside. The spring seats 325 are connected to a return spring 324. The connecting rod 318 has a clearance hole. The return spring 324 passes downward through the clearance hole and connects to the triangular plate 323 for elastic reset of the button 315.

[0039] In some optional specific embodiments, such as Figures 5 to 8 As shown, a support plate 304 is installed in the housing 302. The support plate 304 is located in the middle gap of the conveyor belt and supports the upper part of the conveyor belt. The support plate 304 has multiple ventilation holes to guide the cold air entering from the air inlet 303 to the conveyor belt.

[0040] In some optional specific embodiments, such as Figures 5 to 8 As shown, the conveyor belt includes an unwinding roller 317 and a take-up roller 305. The unwinding roller 317 is located at the rear section of the housing 302, and the take-up roller 305 is located at one end of the housing 302 near the handle 314. A friction wheel is installed at the end of the take-up roller 305, and the friction wheel is driven by friction with the moving plate 312.

[0041] In some optional specific embodiments, such as Figures 5 to 8 As shown, multiple sets of partition strips 313 are connected between the two movable plates 312. Each partition strip 313 consists of two sections respectively fixed to the movable plate 312, and the two sections are connected by snap-fit. The partition strips 313 divide the interior of the storage component 301 into multiple storage positions. The side plate 309 has a partition strip movement opening 311 on its inner side and an installation groove 310 inside its interior for the pulling and pulling of the movable plate 312. When the partition strips 313 pass the insulation plate 308, the snap-fit ​​connection contacts under the action of tension. The partition strips 313 divide the interior of the storage component 301 into multiple storage positions, preventing the slow accumulation and compression of the snow skin mooncakes due to the inertia of repeated removals when the conveyor belt is pulled.

[0042] In some optional specific embodiments, such as Figures 9 to 11 As shown, a top rod 401 connects the movable plate 312 to the top wall of the handle 314. A movable support rod 402 is installed at the end of the movable plate 312 away from the handle 314. A ball bearing 403 is installed at the bottom of the movable support rod 402. A hydraulic channel is provided inside the movable plate 312. The top rod 401 drives the movable support rod 402 to extend by squeezing the filling liquid in the hydraulic channel, thus supporting the end of the movable plate 312. When selecting the filling liquid, it is sufficient to choose one with a freezing point higher than the refrigeration temperature of the snow skin mooncake.

[0043] In some optional specific embodiments, such as Figure 4As shown, guide grooves 203 are respectively opened at both ends of the tray 202. A guide rail 104 adapted to the guide grooves 203 is installed on the inner wall of the refrigeration cavity 103. A cold air vent 204 is opened on the side of the tray 202. The cold air vent 204 is opposite to the air inlet 303 and is used to introduce cold air in the refrigeration cavity 103 into the gap of the conveyor belt and cool and refrigerate the snow skin mooncakes through the exchange section 306.

[0044] In some optional specific embodiments, such as Figure 4 As shown, the front end of the tray 202 is provided with a magnetic baffle, which is hinged to the bottom of the tray 202 and magnetically attracted to the edge of the tray 202 at both ends. During use, the storage component 301 can be removed as a whole.

[0045] The working principle of this invention is as follows: During use, the snow skin mooncakes are neatly arranged in each storage component 301. Different fillings of snow skin mooncakes can be placed in different storage components 301. When a snow skin mooncake needs to be removed, the cabinet door 102 is opened, and the handle 314 of one of the storage components 301 is pulled. This pulls out a moving plate 312. During this pulling process, the moving plate 312 drives a conveyor belt through friction transmission, causing the mooncakes on the conveyor belt to fall. The worker can then catch the mooncakes from below. During this process, it is not necessary to open other drawer components 201. In addition to other storage components 301, heat exchange with the outside is greatly reduced. After the snow skin mooncake is taken out, the button 315 is pressed to drive the moving plate 312 to move up a certain distance in the side plate 309, so that the friction transmission between the moving plate 312 and the conveyor belt is released. The handle 314 is pushed back to return the moving plate 312 and the handle 314 to their original positions. At this time, the insulation plate 308 moves forward a certain distance. The insulation plate 308, together with the insulation section 307 of the conveyor belt moving forward, provides a certain degree of insulation for the empty space, which can reduce the cooling space, improve work efficiency, and reduce energy consumption.
