Description

Technical Field

[0001] The present application relates to the field of refrigeration equipment, and particularly to a two- or three-door sliding door drawer island cabinet. Background Art

[0002] With the development of modern commerce, various types of freezing and refrigeration equipment are widely used in supermarkets, convenience stores and other retail places to keep food fresh. An island cabinet is a large freezer mainly used for freezing food and is suitable for business places that need to store food for a long time, such as the sales of frozen food and aquatic products. Island cabinets usually have a large capacity and can provide a larger storage space, which is especially suitable for foods that need to be stored for a long time.

[0003] Generally, a freezer is refrigerated through a condenser or a refrigeration chip, and then the refrigerated cold air is circulated inside the island cabinet. Since the cabinet doors of the island cabinet in the business place need to be frequently opened and closed, it is easy for external air to enter the island cabinet. The moisture in the air follows the cold air circulation and enters the condenser. In a low-temperature environment, the condensation pipes inside the condenser will freeze, which not only reduces the heat exchange efficiency but also may cause equipment failures and increase the maintenance cost. Summary of the Invention

[0004] In order to reduce the icing of the condenser and lower the maintenance cost, the present application provides a two- or three-door sliding door drawer island cabinet.

[0005] The two- or three-door sliding door drawer island cabinet provided by the present application adopts the following technical solutions: A two- or three-door sliding door drawer island cabinet includes a cabinet body. A storage cavity is provided inside the cabinet body. A support plate is fixedly connected to the bottom of the cabinet body inside the storage cavity. A cavity is provided inside the support plate. A plurality of air outlet holes are provided at the top of the support plate. A return cavity is provided on the side wall of the cabinet body. An air inlet hole is provided at the position of the side wall of the cabinet body corresponding to the return cavity. A circulation channel is provided on the side wall of the cabinet body. The circulation channel is communicated with the return cavity. A connection channel is fixedly connected inside the cabinet body. A refrigeration box is provided inside the cabinet body. The connection channel is communicated with the inside of the refrigeration box. An air outlet is provided at the top of the refrigeration box. The air outlet is used to communicate the spare box, the refrigeration box and the cavity of the support plate. A blower is connected to the refrigeration box. A refrigeration mechanism is connected to the refrigeration box. The refrigeration mechanism is used to refrigerate the air inside the refrigeration box.

[0006] By adopting the above technical solution, when the user uses it, one of the fans in the refrigeration box and the spare box works. Here, taking the refrigeration box working first as an example, a negative pressure state is formed inside the refrigeration box, and the air flow in the accommodation cavity enters the reflux cavity through the air inlet hole, and then enters the refrigeration box through the circulation channel and the connection channel. The refrigeration mechanism cools the air flow inside the refrigeration box. The cooled air flow returns to the cavity through the air outlet, and then evenly enters the storage cavity through the air outlet hole, realizing the circulation of cold air. Instead of the traditional direct contact between cold air and the condenser, it prevents moisture in the air from freezing on the condensing pipe. By indirectly refrigerating the circulating cold air, the formation of ice on the condenser is reduced, and the maintenance cost is lowered.

[0007] Optionally, a spare box with the same structure as the refrigeration box is arranged inside the cabinet. The connection channel is communicated with the inside of the spare box, and an air outlet communicating with the cavity is also opened at the top of the spare box. The refrigeration mechanism alternately cools the air in the refrigeration box and the spare box.

[0008] By adopting the above technical solution, when the user uses it, after a period of time, the fan of the spare box is controlled to work, so that cold air circulates between the storage cavity and the spare box, which is convenient for removing the frost condensed in the refrigeration box. At the same time, it does not affect the normal refrigeration of the equipment, does not require shutdown for defrosting, and does not affect the working efficiency of the guide rail.

[0009] Optionally, the refrigeration mechanism includes a refrigerator fixedly connected inside the cabinet. A refrigerant inlet pipe and a refrigerant outlet pipe are fixedly connected to the refrigerator. One ends of the refrigerant inlet pipe and the refrigerant outlet pipe are fixedly connected to the refrigerator, and the other ends are communicated with a compressor; a refrigerant water inlet pipe and a refrigerant water outlet pipe are fixedly connected to the refrigerator. The refrigerant water inlet pipe and the refrigerant water outlet pipe are respectively located at both ends of the refrigerator. The refrigerant water inlet pipe and the refrigerant water outlet pipe introduce refrigerant into the refrigerator for heat exchange and cooling, and the refrigerant water outlet pipe introduces the cooled refrigerant into the refrigeration box and the spare box.

[0010] By adopting the above technical solution, when the user uses it, the refrigerant inlet pipe and the refrigerant outlet pipe are used to circulate the refrigerant between the compressor and the refrigerator. The refrigerant water inlet pipe and the refrigerant water outlet pipe introduce the refrigerant into the refrigerator to exchange heat and cool down with the refrigerant, realizing the delivery of refrigerant to the refrigeration box and the spare box, and refrigerating the air in the refrigeration box and the spare box.

[0011] Optionally, a three-way valve is fixedly connected to the refrigerant outlet pipe, and a material collecting box is fixedly connected to the refrigerant inlet pipe. The three-way valve is fixedly connected with a first refrigeration pipe and a second refrigeration pipe. The three-way valve is used to automatically control the connection of the refrigerant outlet pipe with one of the first refrigeration pipe and the second refrigeration pipe. One end of the first refrigeration pipe extends into the refrigeration box, and the other end of the first refrigeration pipe extends out of the refrigeration box and is fixedly connected to the material collecting box; one end of the second refrigeration pipe extends into the spare box, and the other end of the second refrigeration pipe extends out of the spare box and is fixedly connected to the material collecting box.

[0012] By adopting the above technical solution, when the user uses it, the three-way valve automatically controls the connection of the refrigerant outlet pipe with one of the first refrigeration pipe and the second refrigeration pipe, and the first refrigeration pipe and the second refrigeration pipe are used to exchange heat and refrigerate the air in the refrigeration box or the spare box.

[0013] Optionally, baffles are arranged at the positions of the air outlets of the spare box and the refrigeration box. The size of the baffle is larger than the size of the air outlet. One side of the baffle is fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the tops of the spare box and the refrigeration box. The side of the baffle away from the rotating shaft is arranged as a free end.

[0014] By adopting the above technical solution, when the user uses it, the fan works, resulting in a negative pressure state in the refrigeration box or the spare box. The setting of the baffle can ensure that the cold air in the refrigeration box or the spare box can enter the cavity, and prevent the air flow in the cavity from entering the refrigeration box and the spare box through the air outlet. The baffle forms the function of a one-way valve at the position of the air outlet.

[0015] Optionally, drain pipes are fixedly connected to the bottoms of the refrigeration box and the spare box, and a water collecting tank is fixedly connected to the bottom inside the cabinet, and an evaporator is connected to the water collecting tank.

[0016] By adopting the above technical solution, when the user uses it, when the first refrigeration pipe in the refrigeration box freezes, the fan of the refrigeration box is controlled to stop working, and at the same time, the fan on the spare box is controlled to work. The three-way valve closes the first refrigeration pipe and opens the second refrigeration pipe. The air flow circulates and refrigerates through the spare box, and the frost on the first refrigeration pipe in the refrigeration box automatically melts. The melted water enters the water collecting tank and finally is heated and evaporated by the evaporator.

An inclined surface is formed on the clamping ridge 152, and the inclined surface facilitates the clamping of the gas guide column 15 in the air guide hole. A cover plate 153 is fixedly connected to the top of the gas guide column 15. The cover plate 153 is arc-shaped. A plurality of notch grooves 154 are formed in the cover plate 153. The notch grooves 154 are used for guiding out the air flow. The cover plate 153 can block the air outlet hole 142 to prevent the stored food from blocking the air outlet hole 142 and unable to carry out normal cold air circulation.

[0029] In addition, the moisture and liquid in the food may flow into the cavity 141 through the air guide hole. A discharge channel 16 is formed in the side wall of the cabinet body 1. One end of the discharge channel 16 is communicated with the cavity 141, and the other end extends out of the cabinet body 1 and is plugged with a plug 161. Moreover, the whole support plate 14 inclines downward toward the discharge channel 16 to facilitate the flow of sewage and the like in the direction of the discharge channel 16. Removing the plug 161 facilitates the discharge of the sewage in the discharge channel 16 to the outside.

[0030] Refer to Figure 4 and Figure 5, on both side walls of the cabinet body 1 perpendicular to the drawer 13, a return flow cavity 17 is provided. At positions near both ends of the cabinet body 1, a plurality of air inlet holes 171 are provided. The air inlet holes 171 communicate the storage cavity 11 with the inside of the return flow cavity 17, facilitating the cooling circulation of the air flow in the storage cavity 11 and storing the products in the storage cavity 11 at a low temperature. On the side wall of the cabinet body 1, two circulation channels 18 are provided. The circulation channels 18 are located at both ends of the cabinet body 1 on the side away from the drawer 13. The circulation channels 18 are vertically arranged and communicate with the inside of the return flow cavity 17. A connection channel 19 is fixedly connected inside the cabinet body 1.

The connection channel 19 communicates with the inside of the refrigeration box 20, and the connection channel 19 communicates with the inside of the spare box 21. A blower 22 is fixedly connected inside both the refrigeration box 20 and the spare box 21. The blowers 22 in the refrigeration box 20 and the spare box 21 work alternately; on the top of both the spare box 21 and the refrigeration box 20, an air outlet 201 is provided. The air outlet 201 is used to communicate the spare box 21, the refrigeration box 20 with the cavity 141 of the support plate 14. At the position of the air outlet 201 on both the spare box 21 and the refrigeration box 20, a baffle 202 is provided. The size of the baffle 202 is larger than the size of the air outlet 201. One side of the baffle 202 is fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the top of the spare box 21 and the refrigeration box 20. The side of the baffle 202 away from the rotating shaft is arranged as a free end. A refrigeration mechanism 3 is connected to both the refrigeration box 20 and the spare box 21. The refrigeration mechanism 3 is used to refrigerate the air inside the refrigeration box 20 and the spare box 21.

[0031] When the blower 22 works, a negative pressure state is formed inside the refrigeration box 20 and the spare box 21. The air flow in the accommodation cavity enters the return flow cavity 17 through the air inlet holes 171, and then enters the refrigeration box 20 or the spare box 21 through the circulation channels 18 and the connection channel 19. The refrigeration mechanism 3 cools down the air flow inside the refrigeration box 20 or the spare box 21. The cooled air flow pushes open the baffle 202 and then returns to the cavity 141, and then evenly enters the storage cavity 11 through the air outlet holes 142, realizing the circulation of the cold air.

[0032] Referring to Figure 6 and Figure 7 , the refrigeration mechanism 3 includes a refrigerator 31 fixedly connected inside the cabinet body 1. A refrigerant inlet pipe 32 and a refrigerant outlet pipe 33 are fixedly connected to the refrigerator 31. One ends of the refrigerant inlet pipe 32 and the refrigerant outlet pipe 33 are fixedly connected to the refrigerator 31, and the other ends are connected to a compressor. The refrigerant inlet pipe 32 and the refrigerant outlet pipe 33 are used to circulate the refrigerant between the compressor and the refrigerator 31.

[0033] A refrigerant inlet pipe 34 and a refrigerant outlet pipe 35 are fixedly connected to the refrigerator 31. The refrigerant inlet pipe 34 and the refrigerant outlet pipe 35 are respectively located at both ends of the refrigerator 31. The refrigerant inlet pipe 34 and the refrigerant outlet pipe 35 introduce the refrigerant into the refrigerator 31 for heat exchange and cooling. Among them, a three-way valve 36 is fixedly connected to the refrigerant outlet pipe 35, and a material collecting box 37 is fixedly connected to the refrigerant inlet pipe 34. A first refrigeration pipe 361 and a second refrigeration pipe 362 are fixedly connected to the three-way valve 36. The three-way valve 36 is used to automatically control the connection of the refrigerant outlet pipe 35 with one of the first refrigeration pipe 361 or the second refrigeration pipe 362. One end of the first refrigeration pipe 361 extends into the refrigerating chamber 20, and the first refrigeration pipe 361 is distributed in a serpentine shape in the refrigerating chamber 20. The other end of the first refrigeration pipe 361 extends out of the refrigerating chamber 20 and is fixedly connected to the material collecting box 37. One end of the second refrigeration pipe 362 extends into the spare chamber 21, and the second refrigeration pipe 362 is distributed in a serpentine shape in the spare chamber 21. The other end of the second refrigeration pipe 362 extends out of the spare chamber 21 and is fixedly connected to the material collecting box 37. The first refrigeration pipe 361 and the second refrigeration pipe 362 are used to exchange heat and refrigerate the air in the refrigerating chamber 20 or the spare chamber 21.

[0034] Drain pipes 38 are fixedly connected to the bottoms of the refrigerating chamber 20 and the spare chamber 21, and a water collecting tank 39 is fixedly connected to the inner bottom of the cabinet body 1. An evaporator 391 is connected to the water collecting tank 39. When the first refrigeration pipe 361 in the refrigerating chamber 20 freezes, the blower 22 of the refrigerating chamber 20 is controlled to stop working, and at the same time, the blower 22 on the spare chamber 21 is controlled to work. The three-way valve 36 closes the first refrigeration pipe 361 and opens the second refrigeration pipe 362. The air flow circulates and refrigerates through the spare chamber 21, and the frost on the first refrigeration pipe 361 in the refrigerating chamber 20 automatically melts. The melted water enters the water collecting tank 39 and is finally heated and evaporated by the evaporator 391.

[0035] The implementation principle of a two- or three-door sliding door drawer island cabinet in an embodiment of the present application is as follows: The blower 22 works to make the refrigerating chamber 20 and the spare chamber 21 in a negative pressure state. The air flow in the accommodation cavity enters the return cavity 17 through the air inlet hole 171, and then enters the refrigerating chamber 20 through the circulation channel 18 and the connection channel 19. The refrigerant in the refrigerant outlet pipe 35 is introduced into the refrigerating chamber 20 through the first refrigeration pipe 361. The refrigerant in the first refrigeration pipe 361 exchanges heat with the heat in the air in the refrigerating chamber 20, and the refrigerant in the first refrigeration pipe 361 takes away the heat, thereby cooling the air in the refrigerating chamber 20. The cooled air flow pushes open the baffle 202 and then returns to the cavity 141, and then evenly enters the storage cavity 11 through the air outlet hole 142, realizing the circulating flow of cold air.

[0036] Among them, the air in the cycle exchanges heat in the refrigeration box 20, and the moisture carried in the air freezes outside the first refrigeration pipe 361, replacing the traditional direct contact between the air and the condensing pipe on the refrigerator 31, thereby preventing the condensing pipe on the refrigerator 31 from freezing. The spare box 21 and the refrigeration box 20 are used alternately, which is convenient for automatically defrosting and cleaning the frozen first refrigeration pipe 361 or the second refrigeration pipe 362.

[0037] Moreover, the island cabinet of the present invention has a compact structure, clear division of functional areas, and meets the diverse needs of users; the setting of the sealing strip effectively solves the problem of poor sealing of the sliding door 121, reducing the energy consumption of the equipment; the design of the sliding door 121 enables users to easily open and close it, and the setting of the drawer 13 also facilitates users to quickly access items.

[0038] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
