Description

Technical Field

[0001] This utility model relates to the field of refrigerated storage cabinet technology, and in particular to a double-door refrigerated grid cabinet. Background Technology

[0002] The double-door refrigerated cabinet of the vending machine is the core device for storing and selling goods at low temperatures. It needs to be adapted to the high-frequency cabinet door opening and closing scenario of dozens to hundreds of times a day. It also needs to meet the requirements of unmanned maintenance, multi-category storage and outdoor use. Its performance is directly related to the vending machine's energy saving, product freshness and user experience.

[0003] Existing refrigerated cabinets have significant drawbacks: frequent opening and closing can easily cause the door's sealing structure to fail, resulting in a large amount of cold air leakage; the refrigeration system also has a slow response and cannot quickly restore the internal temperature, affecting energy efficiency and product preservation; in outdoor environments, the cabinet door surface is prone to fogging when there are temperature changes, severely obstructing vision and affecting the user's purchasing experience. Utility Model Content

[0004] To overcome the shortcomings of frequent opening and closing that can easily lead to failure of the sealing mechanism, inability of the internal temperature to recover quickly, and easy fogging on the cabinet door surface, the technical problem to be solved is to provide a double-door refrigerated grid cabinet.

[0005] The technical solution is as follows: A double-door refrigerated grid cabinet includes a first and a second cabinet body. The cabinet body is rotatably connected to symmetrically distributed cabinet doors. A display is fixedly connected to each cabinet door. A sealing component for maintaining a seal is provided on each cabinet door. A uniformly distributed fixed frame is slidably connected to the cabinet body. A uniformly distributed observation window is rotatably connected to the fixed frame. An evaporator is provided inside the cabinet body. A compressor is provided inside the cabinet body. A defogging component for preventing fogging is provided inside the cabinet body. The sealing assembly includes: symmetrically distributed sealing glass, each of which is fixedly connected to an adjacent cabinet door; uniformly distributed sealing strips are fixedly connected to the cabinet body; elastic airbags are provided on the uniformly distributed sealing strips; the sealing strips are slidably connected to the adjacent cabinet doors; and electromagnetic adsorption strips are provided on both the cabinet body and the symmetrically distributed cabinet doors.

[0006] Furthermore, the spaces between adjacent and symmetrically distributed sealing glass panes are filled with an inert gas.

[0007] Furthermore, an alignment guide block is fixedly connected to the cabinet door. The alignment guide block is gradually tilted upward at 15° from left to right. The alignment guide block is wedge-shaped, wider at the front and narrower at the back. Alignment grooves are provided on adjacent cabinet doors. The alignment guide block is slidably connected to the adjacent cabinet door. A strong magnetic block is provided between the alignment guide block and the adjacent cabinet door.

[0008] Furthermore, a phase change cold storage layer is provided on the evaporator, and variable frequency fans are evenly distributed inside the cabinet near the cabinet door.

[0009] Furthermore, the defogging component includes: symmetrically distributed air guide shells, the symmetrically distributed air guide shells being fixedly connected to the side of the cabinet door away from the electromagnetic adsorption strip, an air collection hood being fixedly connected inside the cabinet, the air collection hood being fixedly connected to the compressor, a fan being provided inside the cabinet, and the fan being connected to both the air collection hood and the symmetrically distributed air guide shells.

[0010] Furthermore, the air guide shell is provided with an air guide channel, and the side of the air guide channel away from the sealing strip is inclined from top to bottom towards the side closer to the sealing strip.

[0011] Furthermore, it also includes evenly distributed storage components for arranging placed items. The storage components are disposed on the fixed frame and include: a storage frame slidably connected to the fixed frame; an elastic element between the storage frame and the fixed frame; a reset rod slidably connected within the storage frame; an elastic element between the reset rod and the storage frame; a trigger rod slidably connected within the reset rod; an elastic element between the trigger rod and the storage frame; symmetrically distributed limiting rods slidably connected within the reset rod; a limiting groove within the trigger rod; and the trigger rod is slidably connected to the symmetrically distributed limiting rods via the limiting groove, with the limiting rods engaging with the storage frame for limiting.

[0012] The beneficial effects are as follows: This utility model uses a dual structure of elastic airbag and electromagnetic adsorption strip, combined with wedge-shaped alignment guide block and strong magnetic block positioning, to solve the problem of sealing failure caused by high frequency opening and closing, greatly reduce cold air leakage, reduce refrigeration energy consumption, and fill the sealed glass with inert gas to further improve the heat preservation performance. The phase change cold storage layer cools down when the door is open and leaks cold, and the inverter air cooling system quickly replenishes the cold after the door is closed, helping the temperature inside the cabinet to recover quickly, buying time for the refrigeration system to respond and reducing the number of high-frequency compressor starts. The heat generated by the compressor is collected by the air collection hood, and then the hot air is directed to the cabinet door through the air guide shell, which effectively eliminates the fogging of the glass caused by temperature difference and ensures that users can see and clean the glass. The goods are placed in the storage baskets, and then the goods are sorted out using the reset lever and trigger lever, reducing the frequency of manual sorting. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings. Example 1

[0021] A type of double-door refrigerated cabinet, such as Figure 1 and Figure 2 As shown, the cabinet includes a cabinet body 1, which is rotatably connected to symmetrically distributed cabinet doors 2. A display is fixed to each cabinet door 2, and a sealing component 3 is provided on each cabinet door 2 to maintain a seal. A uniformly distributed fixed frame 4 is slidably connected inside the cabinet body 1 for holding goods. The fixed frame 4 is rotatably connected to a uniformly distributed observation window 401. An evaporator 5 is installed inside the cabinet body 1, and a phase change cold storage layer 501 is installed on the evaporator 5. A uniformly distributed variable frequency fan 502 is installed inside the cabinet body 1. The phase change cold storage layer 501 collects and stores the cold energy on the surface of the evaporator and releases it when the cabinet door 2 is opened to slow down the temperature rise inside the cabinet. The variable frequency fan 502 quickly cools down the door opening to further alleviate the temperature rise. A compressor 6 is installed inside the cabinet body 1, and a defogging component 7 is installed inside the cabinet body 1 to prevent fogging. like Figures 2-4As shown, the sealing assembly 3 includes: symmetrically distributed sealing glass 301s, with inert gas filling the spaces between adjacent and symmetrically distributed sealing glass 301s to improve the thermal insulation performance of the cabinet 1 and prevent fogging caused by temperature drops in the outer sealing glass 301, which would affect the user's viewing of the goods inside the cabinet. The symmetrically distributed sealing glass 301s are all fixedly connected to adjacent cabinet doors 2. Uniformly distributed sealing strips 302 are fixedly connected to the cabinet 1, and elastic airbags 303 are provided on the uniformly distributed sealing strips 302. The sealing strips 302 are slidably connected to adjacent cabinet doors 2. Electromagnetic adsorption strips 304 are provided on both the cabinet 1 and the symmetrically distributed cabinet doors 2. The electromagnetic adsorption strips 304 trigger the elastic airbags 303 on the sealing strips 302, thus sealing the strips. The gap between cabinet door 2 and cabinet 302 is filled to increase the sealing between cabinet door 2 and cabinet body 1. An alignment guide block 305 is fixed on cabinet door 2. The alignment guide block 305 is inclined upward at 15° from left to right. The alignment guide block 305 is wedge-shaped with a wider front and narrower back. Alignment grooves are provided on adjacent cabinet doors 2. The alignment guide block 305 is slidably connected to the adjacent cabinet door 2. Strong magnetic blocks are provided between the alignment guide block 305 and the adjacent cabinet door 2. The upwardly inclined alignment guide block 305 cooperates with the alignment groove on the cabinet door 2 to make the left and right cabinet doors 2 accurately aligned and avoid misalignment. The wedge-shaped alignment guide block 305 with a wider front and narrower back allows the cabinet door 2 to slide with the alignment groove when closed, avoiding door displacement and misalignment caused by high frequency opening and closing.

[0022] like Figure 2 and Figure 3 As shown, the defogging component 7 includes: symmetrically distributed air guide shells 701, which are fixed to the side of the cabinet door 2 away from the electromagnetic adsorption strip 304; an air collection hood 702 is fixed inside the cabinet 1 and is fixed to the compressor 6; a fan 703 is installed inside the cabinet 1, and the fan 703 is connected to both the air collection hood 702 and the symmetrically distributed air guide shells 701; an air guide duct is installed inside the air guide shell 701, and the side of the air guide duct away from the sealing strip 302 gradually slopes from top to bottom towards the side closer to the sealing strip 302; the air collection hood 702 collects the hot air around the compressor 6 and circulates the hot air to the air guide shell 701, so that the water vapor on the surface of the outer sealing glass 301 is carried away by the airflow; at the same time, the heat prevents the sealing glass 301 from falling below the dew point temperature, further preventing fogging of the sealing glass 301; no heating components are required, significantly reducing equipment energy consumption.

[0023] After the device is powered on, the compressor 6 starts and the evaporator 5 starts to cool. The phase change cold storage layer 501 on the surface of the evaporator 5 absorbs and stores the cooling capacity simultaneously. The variable frequency fan 502, which is evenly distributed inside the cabinet, starts to deliver the cooling capacity generated by the evaporator 5 to each area of ​​the cabinet 1, so that the cabinet 1 reaches a stable low temperature environment.

[0024] After the compressor 6 is started, it generates a lot of heat and dissipates it into the surrounding air. The hot air is collected by the air collection hood 702. The hot air in the air collection hood 702 is circulated into the guide shell 701 by the start of the fan 703. The guide shell 701 guides the hot air to the surface of the outer sealing glass 301 through the guide air duct, so that the temperature of the outer sealing glass 301 is slightly increased. At the same time, the water vapor on the surface of the outer sealing glass 301 is blown away to prevent fogging and ensure that the user can clearly see the goods in the cabinet 1.

[0025] When the electromagnetic adsorption strip 304 is energized, the elastic airbag 303 on the sealing strip 302 inflates and expands, filling the gap between the sealing strip 302 and the cabinet door 2, ensuring the sealing effect between the cabinet door 2 and the cabinet body 1. When the user needs to open the cabinet, the electromagnetic adsorption strip 304 is de-energized, the magnetic force disappears, the elastic airbag 303 on the sealing strip 302 depressurizes and contracts, releasing the sealed fit between the cabinet door 2 and the cabinet body 1, making it easier to open the cabinet door 2.

[0026] After the cabinet door 2 is opened, cold air begins to leak out. The phase change cold storage layer 501 on the surface of the evaporator 5 immediately releases the stored cooling capacity, slowing down the rate of temperature rise inside the cabinet and buying time for subsequent cooling replenishment by the refrigeration system. At the same time, the variable frequency fan 502 is controlled to accelerate its rotation, further alleviating the temperature rise after the cabinet door 2 is opened.

[0027] When cabinet door 2 is closed, the wedge-shaped alignment guide block 305 on the left cabinet door 2 slides into the alignment groove on the right cabinet door 2. At the same time, the strong magnetic block between the alignment guide block 305 and the cabinet door 2 attracts each other, guiding the two cabinet doors 2 to be precisely aligned and avoiding misalignment.

[0028] After the cabinet doors 2 are aligned, the electromagnetic adsorption strip 304 is re-energized to generate magnetic force, pulling the left and right cabinet doors 2 closer to the cabinet body 1, so that the cabinet doors 2 and the cabinet body 1 are in close contact. The elastic airbags 303 on the sealing strip 302 are simultaneously inflated and expanded to fill the gap between the cabinet doors 2 and the sealing strip 302. At the same time, the inert gas filled between the double-layer sealed glass 301 reduces the heat exchange between the glass and forms a multi-layer seal to prevent cold air leakage.

[0029] After cabinet door 2 is closed, if the temperature difference between the cabinet and the preset temperature exceeds the set value, the variable frequency fan 502 is controlled to adjust its speed to accelerate the circulation of cold air and quickly restore the temperature inside the cabinet to the set range. Example 2

[0030] like Figure 2 , Figure 5 and Figure 6As shown, it also includes a storage component 8, which is used to arrange placed items. The storage component 8 is disposed on the fixed frame 4 and includes: a storage frame 801, which is slidably connected to the fixed frame 4; an elastic element, which is a tension spring, is disposed between the storage frame 801 and the fixed frame 4; a reset rod 802 is slidably connected inside the storage frame 801; an elastic element, which is a tension spring, is disposed between the reset rod 802 and the storage frame 801; and a trigger rod 803 is slidably connected inside the reset rod 802. An elastic element, which is a spring, is provided between 801. A symmetrically distributed limiting rod 804 is slidably connected inside the reset rod 802. A limiting groove is provided inside the trigger rod 803. The trigger rod 803 is slidably connected to the symmetrically distributed limiting rod 804 through the limiting groove. The limiting rod 804 is in a limiting engagement with the storage frame 801. The engagement of the limiting rod 804 and the trigger rod 803 enables the goods to be automatically returned to their positions, assisting in sorting and reducing the frequency of manual insertion into the cabinet 1 for sorting. The storage frame 801 can be pulled out for operation, so there is no need to insert into the cabinet 1 when replenishing goods, thus improving replenishment efficiency.

[0031] When staff put the goods into cabinet 1, they open the observation window 401 at the corresponding position according to the different specifications of the goods and put the goods into the storage box 801.

[0032] When items are placed in the storage frame 801, the staff pulls the reset rod 802 backward. The tension spring of the reset rod 802 stretches and stores force. At this time, the trigger rod 803 remains in its initial position under the action of the spring, so that the limiting rod 804 does not contact the storage frame 801. The items are then arranged one by one in sequence. After the items are arranged, the staff stops pulling the reset rod 802. The reset rod 802 resets forward under the action of the tension spring until the trigger rod 803 contacts the last item. The reset rod 802 continues to reset, driving the limiting rod 804 forward. The spring of the trigger rod 803 is compressed and stores force. The limiting rod 804 moves away from the trigger rod 803 under the action of the limiting groove of the trigger rod 803 until it contacts and limits the storage frame 801, causing the reset rod 802 to stop moving. This automatically pushes and sorts the items, reducing the frequency of manual insertion into the cabinet 1 for sorting.

[0033] When a user retrieves goods, they select the desired item via display 101. Display 101 controls the opening of the observation window 401 on the front of the corresponding storage frame 801. The observation window 401 swings forward to open, pulling the storage frame 801 outward for easy retrieval. The tension spring between the storage frame 801 and the frame is stretched and stored. After the item is removed, the tension spring returns to its original position, causing the storage frame 801 to automatically reset. The observation window 401 swings downward to close the corresponding storage frame 801. At this point, there is an empty space in front of the storage frame 801. The trigger rod 803 moves forward under the action of the spring, causing the limit rod 804 to release its limit. Then, the reset rod 802 resets forward under the action of the tension spring, moving the item forward along with it until there is no empty space in front of the storage frame 801 and the items are neatly arranged. The trigger rod 803 then re-activates the limit rod 804 to lock the item, achieving automatic return of the items to their original positions. This reduces the frequency of manual sorting and is suitable for unmanned maintenance. During maintenance, the storage frame 801 can be pulled out without needing to be inserted into the cabinet 1.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
