Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a refrigeration workbench and a refrigeration unit that is easy to maintain. Background Art

[0002] The refrigeration workbench is a kind of equipment specially used in laboratories, pharmaceuticals, biological products, food processing and other industries. It provides a low-temperature environment through a built-in refrigeration system to meet the needs of users who need low-temperature working conditions. The refrigeration workbench is widely used in scientific research, pharmaceuticals, food processing and other industries. In the field of scientific research, the refrigeration workbench can provide the necessary low-temperature environment for biological experiments, help researchers preserve experimental samples, and extend the time and accuracy of experiments. In the pharmaceutical field, the refrigeration workbench can be used for the quality control of drugs to ensure that the drugs are not affected by temperature during storage. In the field of food processing, the refrigeration workbench can provide a suitable processing environment for certain foods that require low-temperature processing. The refrigeration mechanism of the refrigeration workbench is called a side-mounted refrigeration unit, also called a plug-in refrigeration unit, which is suitable for various types of air-cooled equipment and can provide efficient cooling and refrigeration effects in a limited space.

[0003] For example, the EPP side-mounted refrigeration unit disclosed in Chinese patent publication number CN219607416U has the following deficiencies in actual use:

[0004] The above patent fixes the compressor, condenser and other refrigeration structures directly to the bottom plate of the unit by bolts, and at the same time, fixes the outer plate to the outer side of the side frame of the unit by bolts to protect the refrigeration unit;

[0005] When the refrigeration unit needs to be inspected and maintained, the maintenance personnel need to remove all the outer panels. Since the outer panels are fixed by several screws, a lot of time is consumed during the removal, resulting in reduced maintenance efficiency. At the same time, the overall mass of the refrigeration unit is heavy, and it is very laborious to manually lift and move it to the outside for inspection and maintenance. Summary of the invention

[0006] In order to improve the problem of difficult overhaul and maintenance and low maintenance efficiency of refrigeration units, the present application provides a refrigeration workbench and a refrigeration unit that is easy to overhaul.

[0007] The present application provides a refrigeration workbench and a refrigeration unit that is easy to repair, which adopts the following technical solutions:

[0008] A refrigeration workbench and a refrigeration unit that is easy to repair, comprising a refrigeration workbench body and a bottom panel fixed to the bottom of one side of the refrigeration workbench body, the refrigeration workbench body is located on one side of the bottom panel and is respectively provided with an air outlet and an air return outlet from top to bottom, a plurality of support plates are fixed on the upper end of the bottom panel, and a top plate fixed to the refrigeration workbench body is provided at the upper end of the bottom panel;

[0009] An equipment compartment is formed between the top plate and the bottom plate;

[0010] A refrigeration unit mechanism for refrigeration is arranged inside the equipment warehouse;

[0011] The refrigeration unit mechanism comprises a guide slot provided on the upper end of a support plate located on one side of the refrigeration workbench body, the guide slot is inclined and one end of the guide slot extends to the end position of the support plate, and one end of the guide slot is provided with two limiting holes connected with the guide slot, and the upper end of the support plate is slidably provided with a connecting bottom plate, and the lower end of the connecting bottom plate is located at the position of the guide slot and is provided with a bearing that moves and limits in the guide slot;

[0012] A foam bag for cooling is fixedly arranged on the upper end of the connecting bottom plate through a longitudinal connecting frame and an upper connecting rod, a U-shaped plate is fixedly arranged on one side of the foam bag, and a reinforcing plate for abutting and limiting the U-shaped plate is fixedly arranged on the lower end of the top plate. When the bearing at the far end is engaged with the limiting hole at the far end, the foam bag of the refrigeration unit mechanism is tightly pressed against the refrigeration workbench body and sealed.

[0013] By adopting the above technical scheme, the movement of the connecting base plate can be guided by the provided guiding long grooves, bearings and connecting columns so that the connecting base plate can be moved along the preset installation route to achieve the effect desired by the designer. At the same time, the cooperation of the U-shaped plate and the reinforcing plate can realize the plug-in limit fixation of one end of the foam bag and then fix one end of the foam bag so that it fits tightly with the refrigeration workbench body. Therefore, the maintenance personnel only need to remove the screws at the other end of the foam bag, which effectively simplifies the installation and disassembly steps of the refrigeration unit mechanism and is very simple and easy.

[0014] Preferably, the refrigeration unit mechanism also includes a fixing frame fixed inside the notch at the lower end of the connecting base plate, and connecting columns protruding from the lower end surface of the connecting base plate are fixed on both sides of the lower end of the fixing frame, and the lower ends of the two connecting columns are fixedly connected to the middle of the bearing.

[0015] By adopting the above technical solution, the fixing frame is used to fix and support the connecting column. At the same time, two avoidance grooves for avoiding the connecting column are provided on one side of the connecting column at the lower end of the connecting base plate. The connecting column can change the moving direction of the connecting base plate, thereby realizing the installation and disassembly of the refrigeration unit mechanism and the refrigeration workbench body.

[0016] Preferably, the two end surfaces of the lower end of the connecting bottom plate are both movably embedded with a plurality of balls in an array that are in contact with the surfaces of the two support plates.

[0017] By adopting the above technical solution, the setting of the ball bearings can effectively reduce the friction between the connecting base plate and the support plate, so that the connecting base plate can move more smoothly and the maintenance personnel will not feel tired due to the weight of the refrigeration unit mechanism.

[0018] Preferably, a right panel fixedly connected to the top panel is fixed between one side of the support plate and the bottom panel, and a horizontal connecting frame fixed to the lower end of the reinforcing plate is fixedly disposed between the right panel located on one side of the refrigeration unit mechanism and the refrigeration workbench body.

[0019] By adopting the above technical solution, the setting of the horizontal connecting frame can make the installation of the right panel more stable and at the same time play a supporting effect. The fixing of the reinforcing plate to the top plate 106 and the horizontal connecting frame further increases the stability of the connection between the top plate, the right panel and the refrigeration workbench body, thereby increasing the stability of the refrigeration workbench structure.

[0020] Preferably, the reinforcing plate is arranged obliquely, the two ends of the U-shaped plate are arranged in an outer "eight" shape, and both ends of the U-shaped plate away from the reinforcing plate are fixed with L-shaped abutment plates, and the ends of the L-shaped abutment plates are arranged as arc chamfers.

[0021] By adopting the above technical solution, the setting of the arc chamfer at the front end of the L-shaped abutment plate can reduce the friction in contact with the L-shaped limit plate while also avoiding noise caused by metal friction. The setting of the reinforcement plate can guide and limit the U-shaped plate to avoid separation of the foam bag from the refrigeration workbench body and cause cold air leakage. The end of the U-shaped plate away from the reinforcement plate can also be fixed to the longitudinal connecting frame to further increase the stability of the U-shaped plate fixation.

[0022] Preferably, an L-shaped limiting plate is fixedly provided at a position corresponding to the L-shaped abutment plate on one side of the refrigeration workbench body, and the contact surface between the L-shaped limiting plate and the L-shaped abutment plate is set as an inclined surface.

[0023] By adopting the above technical solution, the inclined surface of the L-shaped abutment plate can guide the movement of the L-shaped abutment plate so that the foam bag and the refrigeration workbench body are gradually close to each other, thereby achieving insertion fixation of the foam bag and the refrigeration workbench body.

[0024] Preferably, the upper end of the foam bag is provided with a second air blowing port matching the first air blowing port, and the lower end of the foam bag is provided with a second air return port matching the first air return port.

[0025] By adopting the above technical solution, the blowing port two discharges the cold air from the evaporator and discharges it into the interior of the refrigeration workbench through the blowing port one, thereby achieving a refrigeration effect. It should be noted that a sealing strip is provided between the blowing port one and the blowing port two, and the return air port one discharges the cold air inside the refrigeration workbench body and allows the cold air to flow into the foam bag through the return air port two, thereby achieving an energy-saving effect. A sealing strip is provided between the return air port one and the return air port two to fill the gap and avoid air leakage.

[0026] Preferably, the surface of the refrigeration workbench body is fixed to the longitudinal connecting frame and the foam bag through a supporting connecting frame, and the bottom panel is located at a corner on one side of the refrigeration workbench body and is fixed to the surface of the refrigeration workbench body through a corner code.

[0027] By adopting the above technical solution, the setting of the support frame can firmly fix the foam bag on the refrigeration workbench body. The support frame is set at the upper and lower ends of the foam bag, with a total of 4 screws. The small number of screws makes it easy to disassemble while ensuring the stability of the structure. It should be noted that only the screws connecting the support frame and the refrigeration workbench body can be removed, otherwise the foam bag will not be able to be moved out of the equipment compartment.

[0028] Preferably, the right panel is located on one side of the L-shaped limiting plate and is fixedly provided with a rear panel fixedly connected to the bottom panel, the corner bracket and the top panel, the side of the right panel away from the rear panel is fixedly provided with a front panel fixedly connected to the bottom panel, the right panel and the top panel, the front panel is provided with a control panel, and the bottom panel, right panel, rear panel and front panel are all provided with air circulation ports.

[0029] By adopting the above technical solution, the bottom panel, rear panel, top panel, right panel and front panel are connected and fixed to each other by screws, and can be fixed with the help of connectors such as angle brackets. At the same time, the air circulation holes set up can effectively realize the air flow inside the equipment compartment and thus dissipate heat for the compressor.

[0030] Preferably, a flexible sealing strip for sealing is glued and fixed to the contact surface between the foam bag and the refrigeration workbench body, and an inclined plate is fixed between the middle part of one side of the longitudinal connecting frame and the connecting bottom plate to form a triangle.

[0031] By adopting the above technical solution, the flexible sealing strip is arranged to fill the gap between the foam bag and the refrigeration workbench body to achieve a redundancy effect.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The bearing moves in the guide slot and then the connecting column is used to control the moving direction of the connecting bottom plate. At the same time, the reinforcing plate and the U-shaped plate cooperate with each other to make the foam bag move while contacting and completely sticking to the refrigeration workbench body, and at the same time fix one end of the foam bag, eliminating the fixing step, so that the maintenance personnel can fix one side of the foam bag with screws, effectively simplifying the installation and disassembly steps of the refrigeration unit mechanism, improving the efficiency of the maintenance of the refrigeration unit mechanism, saving time and effort;

[0034] 2. With the help of the L-shaped limit plate and the L-shaped abutment plate, redundancy can be achieved for the fixation of one end of the foam bag, further improving the stability of the foam bag fixation, improving the fit between the foam bag and the refrigeration workbench, and effectively avoiding the disadvantages such as air leakage.

[0048] The following is combined with Figure 1 - Fig. 9 This application is described in further detail.

[0049] The embodiments of the present application disclose a refrigeration workbench and a refrigeration unit that is easy to maintain.

[0050] Reference Figure 1 - Figure 4 A refrigeration workbench and a refrigeration unit that is easy to repair, including a refrigeration workbench body 100, a plurality of fixed feet and a top cabinet cover and other structures are fixed at the lower end of the refrigeration workbench body 100, and a bottom panel 102 fixed to the bottom of one side of the refrigeration workbench body 100, a right panel 103 is fixed between one side of a support plate 208 and the bottom panel 102, the upper end of the right panel 103 is fixedly connected to the lower end of the top panel 106, the right panel 103 is located on one side of an L-shaped limiting plate 300 and is fixedly provided with a rear panel 104, the two side edges of the rear panel 104 are respectively fixedly connected to the bottom panel 102, the corner code 105 and the top panel 106, the right panel 103 is fixedly provided with a front panel 101 on the side away from the rear panel 104, and the three side edges of the front panel 101 are respectively fixedly connected to the bottom panel 102, the right panel 103 and the bottom panel 102. 03 and the top plate 106 are fixed by screws, and the other side of the front panel 101 is fixed to the mounting end of the refrigeration workbench body 100 by screws. The front panel 101 is provided with an operation panel, and the operation panel is provided with a touch screen that can display temperature, air volume and other information for easy viewing. At the same time, the refrigeration workbench is provided with hardware such as PCB boards and corresponding software programs. The hardware and devices such as display screens are connected by wires. The bottom panel 102, the right panel 103, the rear panel 104 and the front panel 101 are all provided with air circulation ports. The right panel 103 is located on one side of the refrigeration unit mechanism 200 and is fixed with a horizontal connecting frame 203 between the refrigeration workbench body 100 by screws, and the upper end of the horizontal connecting frame 203 is fixed to the lower end of the reinforcing plate 205 by screws.

[0051] The equipment compartment 109 is formed by splicing the bottom panel 102, the right panel 103, the rear panel 104, one side of the refrigeration workbench body 100 and the front panel 101 together, which effectively improves the aesthetics of the refrigeration workbench and increases the protection of the refrigeration unit mechanism 200. The bottom panel 102, the right panel 103, the rear panel 104, one side of the refrigeration workbench body 100, the top panel 106 and the front panel 101 are all set to metal material.

[0052] Reference Figure 1 - Figure 4The refrigeration workbench body 100 is located on one side of the bottom panel 102 and is respectively provided with a blowing port 107 and a return air port 108 from top to bottom. The blowing port 107 and the return air port 108 are both connected to the cavity or specific pipeline air duct inside the refrigeration workbench body 100 to achieve a cooling effect. The upper end of the foam bag 204 is provided with a blowing port 210 matching the blowing port 107, and the lower end of the foam bag 204 is provided with a return air port 217 matching the return air port 108. The return air port 217 and the blowing port 210 are connected to the inside of the foam bag 204. The front and rear parts of the foam bag 204 are composed of EPp foam splicing and assembly and are the specific shape and structure of the existing technical products. The details are not described here. At the same time, the inside of the foam bag 204 is an evaporating fan and an evaporator, a drain pipe and other structures from top to bottom. At least There are three support plates 208, and the width of the support plate 208 located on one side of the refrigeration workbench body 100 is greater than that of the other two support plates 208, so that the guide long groove 211 has a larger slope. A top plate 106 fixed to the refrigeration workbench body 100 is provided at the upper end of the bottom panel 102; support frames 207 are fixed to both sides of the surface of the refrigeration workbench body 100 by screws, and the side of the support frame 207 away from the refrigeration workbench body 100 is fixed to the mounting end of the longitudinal connecting frame 202 and the mounting end of the foam bag 204 by screws, and the bottom panel 102 is fixed at the corners on one side of the refrigeration workbench body 100 with angle codes 105, and the mounting end of each angle code 105 is fixed to the surface of the refrigeration workbench body 100 by screws, and the two corners of the top plate 106 are fixed to the mounting end on one side of the refrigeration workbench body 100 by linking plates.

[0053] The refrigerant flows inside the evaporator, and the evaporating fan blows the low-temperature air on the surface of the evaporator through the second blowing port 210 and the first blowing port 107 to the inside of the refrigeration workbench body 100, and then returns to the inside of the foam bag 204 through the second return air port 217 and the first return air port 108 to realize circulation. It should be noted that the gap between the second blowing port 210 and the first blowing port 107 is sealed by a sealing strip, and the gap between the second return air port 217 and the first return air port 108 is sealed by a sealing strip. The design of the supporting frame 207, the angle code 105 and the connecting plate and other structures facilitates the disassembly and removal of the refrigeration unit mechanism 200 from the equipment compartment 109. The setting of the screws facilitates disassembly. The maintenance personnel only need to remove the screws connecting the supporting frame 207 and the refrigeration workbench body 100 to slide the refrigeration workbench body 100 out on the upper end of the support plate 208.

[0054] Reference Figure 3 An equipment compartment 109 is formed between the top plate 106 and the bottom plate 102, and a refrigeration unit mechanism 200 for refrigeration is arranged inside the equipment compartment 109.

[0055] Reference Figure 4 - Fig. 9The refrigeration unit mechanism 200 includes a guide slot 211 provided at the upper end of a support plate 208 located on one side of the refrigeration workbench body 100. Both ends of the guide slot 211 are set to be semicircular. The guide slot 211 is inclined and one end extends to the end position of the support plate 208 and the other end extends to one-fifth of the support plate 208. The inclination angle of the guide slot 211 is preferably 2-6 degrees. The width of the guide slot 211 is greater than the outer diameter of the bearing 213 by 1-2 mm. Two limiting holes 212 connected to the guide slot 211 are provided at one end of the guide slot 211. The distance between the two guide slots 211 is the same as that of the guide slot 211. The distance between the two bearings 213 is matched so that simultaneous insertion and limiting can be achieved. The upper end of the second support plate 208 is slidably provided with a connecting bottom plate 201. When the foam bag 204 and the refrigeration workbench body 100 are installed in place, at this time, the connecting bottom plate 201 is just located in the middle of the two support plates 208. The lower end of the connecting bottom plate 201 is located at a corresponding position of the guide long groove 211 and a bearing 213 is provided. The bearing 213 moves in the guide long groove 211 and achieves limiting. The refrigeration unit mechanism 200 also includes a fixing frame 214 fixedly arranged inside the notch at the lower end of the connecting bottom plate 201. The lower end of the connecting bottom plate 201 is provided with inwardly rolled side edges (such as Figure 8 As shown), the fixing frame 214 is installed in the space between the curling edge and the bottom of the connecting base plate 201, and a plurality of cavities are opened in the middle of the connecting base plate 201 to realize a lightweight design. The fixing frame 214 has connecting columns 215 protruding from the lower end surface of the connecting base plate 201 fixedly provided on both sides of the lower end thereof, and the lower ends of the two connecting columns 215 are fixedly connected to the middle of the inner ring of the bearing 213, and the outer ring of the bearing 213 is in contact with the surface of the guide long groove 211. The bearing 213 structure includes an outer ring, an inner ring, a steel ball and other structures. The detailed structure of the product of the prior art is no longer described in detail. The two end surfaces of the lower end of the connecting base plate 201 are arrayed with a plurality of mounting holes, and the two end surfaces of the lower end of the connecting base plate 201 are arrayed with a plurality of balls 218 in contact with the surfaces of the two support plates 208, and the lower ends of the plurality of balls 218 protrude 1-2 mm from the lower end surfaces of the connecting base plate 201 on both sides;

[0056] The fixing frame 214 is made of a magnetic metal material, and the magnetic force of the fixing frame 214 is used to magnetically attract the steel ball 218, thereby adsorbing the ball 218 into the mounting hole to prevent it from falling. At the same time, the structure does not have the ball 218, and the connecting base plate 201 can also slide on the upper end of the support plate 208, because the opposite side surfaces of the connecting base plate 201 and the support plate 208 are both set to be smooth surfaces with low friction.

[0057] The upper end of the connecting bottom plate 201 is also fixed with an aluminum defrosting water tray, a compressor, a pipeline and other structures. The refrigeration structure is the same as the refrigeration equipment structure principle of the existing refrigeration platform, so it will not be described in detail.

[0058] When the maintenance personnel need to maintain the refrigeration unit mechanism 200 of the refrigeration workbench body 100, they need to remove the screws of the front panel 101 with a tool and take out the front panel 101 to expose the refrigeration unit mechanism 200, and then remove the screws connecting the supporting frame 207 and the refrigeration workbench body 100 with a tool, so that the refrigeration unit mechanism 200 is in a state that can be movably disassembled;

[0059] Subsequently, the maintenance personnel hold the connecting position of the longitudinal connecting frame 202 and pull it outward with force. At this time, the longitudinal connecting frame 202 will drive the connecting base plate 201 to slide on the upper ends of the two support plates 208. During the sliding process, the provided ball 218 rolls in the mounting hole and the upper ends of the support plates 208 to reduce the friction. At the same time, the bearing 213 inside one of the limiting holes 212 is stressed, so that the outer ring of the bearing 213 slides on the side of the guide slot 211, thereby separating the bearing 213 from the limiting hole 212, so that the two bearings 213 continue to slide in the guide slot 211, and under the guiding effect of the guide slot 211, the connecting member driven by the bearing 213 is pushed. The column 215 moves toward the side away from the refrigeration workbench body 100, and then drives the fixing frame 214 to move through the connecting column 215, while driving the connecting bottom plate 201 to move, and moves toward one side in an inclined direction until the bearing 213 on the side away from the reinforcing plate 205 abuts against one end of the guide long groove 211. At this time, the foam bag 204 of the refrigeration unit mechanism 200 is completely separated from one side of the refrigeration workbench body 100, and two-thirds of the refrigeration unit mechanism 200 is located outside the refrigeration workbench body 100, and the other parts are also exposed in the equipment compartment 109, which is convenient for maintenance. The above arrangement only needs to be removed by a small number of fastening bolts and then pulled out;

[0060] At the same time, when installing the refrigeration unit mechanism 200, the opposite operation is performed at the same time, the refrigeration unit mechanism 200 is pushed into the equipment compartment 109, so that the bearing 213 is engaged with the limit hole 212, and then the support frame 207 is fixed to the refrigeration workbench body 100 by screws, and then the front panel 101 is installed by screws.

[0061] Reference Figure 4 - Figure 8A longitudinal connecting frame 202 is fixedly provided at the middle of both sides of the upper end of the bottom plate 201, an upper connecting rod 216 is fixed between the upper ends of the two longitudinal connecting frames 202, a foam bag 204 for cooling is fixedly provided between the two longitudinal connecting frames 202 and the upper connecting rod 216, a U-shaped plate 209 is fixedly provided on the side of the foam bag 204 away from the front panel 101, and a reinforcing plate 205 for abutting and limiting the U-shaped plate 209 is fixedly provided at the lower end of the top plate 106, and the reinforcing plate 205 is inclined. When the foam bag When 204 is completely in contact with and sealed against the side wall of the refrigeration workbench body 100, the surface of the reinforcing plate 205 is completely in contact with and limited against the outer surface of the U-shaped plate 209, and the two ends of the U-shaped plate 209 are arranged in an outer "eight" shape. When the distal bearing 213 is engaged with the distal limiting hole 212, the foam bag 204 of the refrigeration unit mechanism 200 is tightly pressed against and sealed against the refrigeration workbench body 100, and a flexible sealing strip for sealing is glued and fixed to the contact surface between the foam bag 204 and the refrigeration workbench body 100.

[0062] When the refrigeration unit mechanism 200 completely enters into the equipment compartment 109, the foam bag 204 drives the U-shaped plate 209 to move and makes the narrower position of the front end of the U-shaped plate 209 contact with one end of the reinforcing plate 205 first. Because the reinforcing plate 205 is inclined, the foam bag 204 can be moved obliquely under the restriction of the reinforcing plate 205. When the U-shaped plate 209 is completely in contact with the surface of the reinforcing plate 205, at this time, the blowing port 210 and the return air port 217 of the foam bag 204 correspond to the blowing port 1 107 and the return air port 1 108 respectively, and are sealed by a flexible sealing strip. The cooperation of the reinforcing plate 205 and the U-shaped plate 209 can make the foam bag 204 away from one end of the supporting frame 207 to be fixed.

[0063] Reference Figure 6 , Figure 8 An inclined plate is fixedly arranged between the middle part of one side of the longitudinal connecting frame 202 and the connecting bottom plate 201 to form a triangle for stability, and both ends of the U-shaped plate 209 away from the reinforcing plate 205 are fixedly arranged with symmetrical L-shaped abutment plates 206, and the ends of the L-shaped abutment plates 206 are arranged with arc chamfers. An L-shaped limiting plate 300 is fixedly arranged at a position corresponding to the L-shaped abutment plate 206 on one side of the refrigeration workbench body 100 to achieve plug-in and tight contact with the L-shaped abutment plate 206, and the contact surface between the L-shaped limiting plate 300 and the L-shaped abutment plate 206 is arranged as an inclined surface. The structural shape of the L-shaped limiting plate 300 is as follows: Figure 3 shown.

[0064] When the narrower position of the front end of the U-shaped plate 209 first contacts one end of the reinforcing plate 205, the front end of the L-shaped abutment plate 206 contacts the sharp part of the L-shaped limiting plate 300 at the same time. Since the contact surface of the L-shaped limiting plate 300 is set as an inclined surface, it will also drive the connecting bottom plate 201 to move obliquely. Therefore, this structure is redundant with the settings of the U-shaped plate 209 and the reinforcing plate 205, effectively improving the installation stability of the foam bag 204.

[0065] The refrigeration workbench 100 and the refrigeration unit mechanism 200 are existing and mature products. How to connect the power supply to be controlled and how to refrigerate are not described in detail. The refrigeration workbench 100 is provided with storage space, cabinet cover, power cord or power interface and other structures.

[0066] The implementation principle of a refrigeration workbench and a refrigeration unit that is easy to repair in the embodiment of the present application is as follows: the device is divided into two steps: installation and disassembly, which are as follows:

[0067] When installing the refrigeration unit mechanism 200:

[0068] At this time, one end of the refrigeration unit mechanism 200 is located outside, and at this time, one of its bearings 213 is in contact with one end of the guide long groove 211. Then, the user pushes the longitudinal connecting frame 202 by hand to make the ball 218 at the bottom of the connecting bottom plate 201 roll on the surface of the support plate 208 until the L-shaped abutment plate 206 gradually contacts and slides with the L-shaped limiting plate 300. At the same time, one end of the U-shaped plate 209 gradually contacts and slides with the surface of the reinforcing plate 205, and then the reinforcing plate 205 and the L-shaped limiting plate 300 are in contact with each other. Under the action, the foam bag 204 and the longitudinal connecting frame 202 are moved through the U-shaped plate 209 and the L-shaped abutment plate 206, and the longitudinal connecting frame 202 drives the connecting bottom plate 201 to slide on the upper end of the support frame and slide obliquely to make the foam bag 204 gradually approach the refrigeration workbench body 100, so that one end of the foam bag 204 first contacts the surface of the refrigeration workbench body 100, and then the contact area gradually increases until it is completely fitted and sealed. At this time, under the action of the bearing 213, the connecting bottom plate 201 will not be separated from the support plate 208;

[0069] When one of the bearings 213 moves to the end of the guide slot 211, the connecting base plate 201 is restricted from moving. At this time, under the action of the reinforcing plate 205 and the L-shaped limiting plate 300, the connecting base plate 201 rotates and deviates with one of the bearings 213 as the rotation axis, so that the other bearing 213 is stuck in one of the limiting holes 212. At this time, the air outlet 210 and the return air outlet 217 correspond to the air outlet 1 107 and the return air outlet 1 108 respectively, and the flexible sealing strip is squeezed and the other bearing 213 is always stuck in one of the limiting holes 212 under the reaction force of the flexible sealing strip to prevent the refrigeration unit mechanism 200 from separating from the refrigeration workbench body 100. Subsequently, the maintenance personnel use tools to screw the refrigeration workbench body 100 and the supporting frame 207 first, and then fix the front panel 101 and the refrigeration workbench body 100 with screws. The above operation only requires three steps to install the refrigeration unit mechanism 200, and the operation is simple.

[0070] When installing the refrigeration unit mechanism 200:

[0071] Only the steps for installing the refrigeration unit mechanism 200 need to be reversed. First, the fixing screws of the front panel 101 and the refrigeration workbench body 100 are removed, and then the fixing screws of the refrigeration workbench body 100 and the supporting frame 207 are removed. Subsequently, the user pulls the refrigeration unit mechanism 200 with force. Because one of its bearings 213 is stuck in the limiting hole 212, it is necessary to use force to remove the front end. When one of its bearings 213 is separated from the limiting hole 212, it is no longer difficult to remove the refrigeration unit mechanism 200. The maintenance personnel directly pull the refrigeration unit mechanism 200 out of the equipment compartment 109 so that the refrigeration unit mechanism 200 is located outside for easy maintenance. Therefore, the disassembly of the refrigeration unit mechanism 200 also only requires three steps. Compared with the existing installation and disassembly of the refrigeration unit mechanism 200, it effectively saves maintenance time and operating steps, and improves work maintenance efficiency.

[0072] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
