In a first embodiment, as shown in fig. 1 to 12, an island cabinet includes a cabinet body 1, a glass window 2, a glass sliding door 3, and a refrigeration system 4. When the island cabinet is in actual use, the cabinet body 1 can be divided into an end cabinet 11 and a straight cabinet 12 according to different installation and arrangement positions. As shown in fig. 1, the two side walls of the straight cabinet 12 are provided with glass windows 2, and as shown in fig. 12, the three side walls of the end cabinet 11 are provided with glass windows 2. The

end cabinets

11 and 11, the end cabinets 11 and the straight cabinets 12, and the

straight cabinets

12 and 12 can be combined and arranged at will. Wherein, the glass window 2 needs to have better heat preservation performance, and the glass sliding door 3 is arranged at the top end of the cabinet body 1.

Wherein, the evaporimeter sets up the rear surface in the storing cavity and vertical arrangement. Specifically, the glass window is not arranged on the back of the cabinet body under the ordinary condition, so that the evaporator can be arranged on the rear surface of the storage cavity in a large area, the evaporator is placed in a large enough area by fully utilizing the area of the rear surface of the storage cavity, and the requirement of internal refrigeration of the storage cavity is met.

And in the use process, the cold energy released by the evaporator is used for refrigerating the articles in the storage cavity in a heat radiation mode, so that direct cooling type refrigeration is realized. In addition, because the evaporator is arranged on the rear surface of the storage cavity, the principle that cold air in the storage cavity sinks and hot air rises is utilized, the refrigerated air subjected to heat exchange by the evaporator sinks to the bottom of the storage cavity at the rear part of the storage cavity, and the air temperature in the front part of the storage cavity is relatively high and rises to the top of the storage cavity. The reverse flow of the air at the front side and the rear side of the storage cavity body can promote the air in the storage cavity body to circularly flow in the front-rear direction, so that the cold air can flow in a self-circulation mode under the condition of no fan drive, and the air-cooled refrigeration effect can be achieved.

Further, a first mesh grid 70 is arranged in the storage cavity, and the first mesh grid 70 is arranged on the front side of the evaporator.

Specifically, since the evaporator is disposed on the rear surface of the storage cavity, in order to reduce the damage to the evaporator caused by the user taking and placing the articles, a first grid 70 is disposed at the front side of the evaporator. The first mesh grid 70 is positioned at the front side of the evaporator and can protect and shield the evaporator, and meanwhile, the first mesh grid 70 can reduce the release and conduction of the cold energy of the evaporator to the maximum extent so as to meet the requirement of direct cooling and heat transfer of the evaporator; in addition, the first mesh grid 70 can also reduce the blockage of the air flow to the maximum extent so as to meet the requirement of the air self-circulation flowing in the storage cavity.

In order to place articles conveniently, a second mesh grid 13 is further arranged in the storage cavity, and the second mesh grid 13 is arranged on the front surface in the storage cavity and is opposite to the first mesh grid 70; the island cabinet further comprises a commodity shelf 14, and the commodity shelf 14 is overlapped between the first mesh grid 70 and the second mesh grid 13.

Specifically, to island cabinet in the in-service use in-process, because the degree of depth of storing cavity is darker and cross sectional area is great, for the access of convenient article, generally adopt supporter 14 to put article in subregion and/or layering. And the first mesh grid 70 and the second mesh grid 13 which are oppositely arranged are arranged in the storage cavity, so that the commodity shelf 14 can be lapped between the two mesh grids, and the commodity shelf 14 can be conveniently installed and fixed. While first mesh grid 70 may protect the evaporator on the one hand and also function to support shelf 14 on the other hand.

In addition, the cabinet body 1 is inside to be provided with a plurality of supporter 14 usually, and the top of general supporter 14 is the load line, need be provided with the fan on the traditional forced air cooling island cabinet, in order to reduce condensation frost on door closure or the lateral wall glass window, the position of general load line is close to cabinet body inside depths. According to the invention, defrosting is carried out through heat radiation in a direct cooling mode, and even if the distance between the glass sliding door 3 and the load line is small from the load line to the door cover on the traditional air-cooled island cabinet, frosting can be avoided on the glass sliding door 3 and the side wall glass window 2, so that the effective utilization volume of the interior of the cabinet body 1 can be increased, and the volume waste and the energy waste are reduced.

Further, on the basis of the above technical scheme, the evaporator 7 is a fin evaporator, which includes a refrigerant pipe and fins, and fin expansion pipes are formed on the refrigerant pipe 7. After long-time use, frost is generated on the evaporator 7, and the frost is heated and dissolved by using a conventional electric heating mode, so that great fluctuation influence is caused on the temperature in the cabinet body 1.

In order to reduce the influence on the temperature in the cabinet 1 during defrosting, hot defrosting is preferably adopted, specifically, a bypass pipe 81 is connected in parallel to the throttle device 8, and an electromagnetic valve 82 is connected in series to the bypass pipe 81. When defrosting is needed, the electromagnetic valve 82 is turned on, so that the refrigerant output from the condenser directly enters the evaporator without throttling, and efficient defrosting is achieved. And in the defrosting process, the evaporator releases heat from inside to outside, so that on one hand, frost can be cleaned more thoroughly, and on the other hand, the influence on the temperature in the storage cavity can be reduced to the maximum extent, so that the storage effect is improved.

According to the invention, the frost on the evaporator 7 is defrosted from inside to outside through the flow of the liquid refrigerant with relatively high temperature in the compressor 5 in the pipeline, so that a more thorough defrosting effect can be realized, the influence of the traditional electric heating mode on the temperature in the cabinet body can be solved, and the influence on frozen and refrigerated goods is avoided. The bypass pipeline 81 is arranged below the refrigerant pipe of the evaporator 7, and the heat released by the bypass pipeline 81 can be used for realizing the defrosting sequence from bottom to top, so that the defrosting efficiency is improved.

Further, a drain pan 9 may be disposed at the bottom of the evaporator, and the drain pan 9 may be disposed below the evaporator 7. The arrangement of the water receiving plate 9 is convenient for the water after defrosting on the evaporator 7 to flow out in time; the water receiving tray 9 can be further provided with an electric heating wire, and the electric heating wire is mounted on the water receiving tray 9, so that the phenomenon that the water outlet of the water receiving tray 9 is frozen due to low temperature in the water discharging process to influence water discharging can be effectively prevented.

Similarly, as shown in fig. 9, a gate line 83 may be provided between the condenser 6 and the expansion device 8, and the gate line 83 may be provided above the refrigerant pipe of the evaporator 7. And a door seal pipeline 83 is arranged above the refrigerant pipe, so that the heat refrigerant output by the condenser 6 enters the door seal pipeline 83 to heat the glass sliding door 3 at the top of the cabinet body 1 through the door seal pipeline 83. Therefore, when the glass sliding door 3 is frequently opened and closed, the glass sliding door 3 is prevented from frosting and freezing, the constant temperature state is kept, and the effect of displaying goods is better played.

On the basis of the technical scheme, the glass window 2 can adopt a hollow structure with four glasses and three cavities so as to effectively improve the heat-insulating property and reduce the occurrence of condensation.

For example: as shown in fig. 6, the hollow glass comprises a first hollow glass 21 and a second hollow glass 22, the first hollow glass 21 and the second hollow glass 22 are fixedly connected to each other and form a cavity, a heat reflective film 23 is symmetrically disposed on an inner wall of the cavity, a side of the interior of the first hollow glass 21 opposite to the second hollow glass 22 is plated with the heat reflective film 23, and a side of the interior of the second hollow glass 22 opposite to the first hollow glass 21 is also plated with the heat reflective film 23.

Or, as shown in fig. 7, based on the above technical solution, the glass window 2 includes vacuum glass 24 and third insulating glass 25, the vacuum glass 24 and the third insulating glass 25 are fixedly connected to form a cavity, and glass beads 26 are disposed inside the vacuum glass 24. Three cavity structures of four glasss of glass window 2 set up to carry out the mode that combines for vacuum glass 24 and cavity glass 25 in this embodiment, not only can guarantee at the in-process of freezing cold-stored goods, and glass window 2 is difficult for the condensation frost, can also carry out effectual heat preservation to the cabinet body 1 inside, and it is effectual to keep warm, reduces the energy consumption in the in-service use, and is more energy-concerving and environment-protective.

Further, the cavity is filled with argon. In order to prevent the fogging and frosting of the conventional glass window, an electric heating component is usually added in the glass window, so that the temperature inside the cabinet body is increased, the storage temperature of goods is influenced, and the energy consumption is increased. According to the invention, a four-glass three-cavity hollow structure is adopted, inert gas argon is filled in a three-layer cavity formed by four layers of glass, and the heat reflection films 23 are symmetrically arranged, so that the heat insulation effect of the glass window 2 can be effectively improved, the heat insulation effect in the cabinet body 1 is good, the display effect can be prevented from being influenced under the condition that condensation and frost are formed on the glass window 2, and meanwhile, the additional energy consumption of the traditional electric heating type glass window can be avoided, and the energy is saved more.

On the basis of the technical scheme, the glass sliding door 3 is of an up-and-down sliding structure, the glass sliding door 3 comprises a first sliding door 31, a second sliding door 32 and a fixed door 33, the first sliding door 31 and the second sliding door 32 are both in sliding connection with the cabinet body 1, and the fixed door 33 is fixedly arranged on the cabinet body 1.

On the basis of the above technical solution, a gas-liquid separator 51 is installed between the inlet of the compressor 5 and the evaporator 7. The gas-liquid separator 51 ensures that the liquid components in the pipeline flowing back to the compressor 5 are gasified and then flow back to the compressor 5, thereby reducing the damage to the compressor 5 and prolonging the service life of the compressor.

On the basis of the technical scheme, the cold storage rack comprises a non-cold storage rack 10, wherein the non-cold storage rack 10 is fixedly arranged at the top of the cabinet body 1. By arranging the non-cold goods shelf 10, the display space of the integral combined island cabinet and the types of displayed goods can be increased, and the practicability is better.

During the refrigeration operation, the electromagnetic valve 82 on the bypass pipe 81 is closed, the refrigerant in the high-pressure gas state in the compressor 5 is converted into the refrigerant in the high-pressure liquid state after passing through the condenser 6, then the refrigerant in the high-pressure liquid state enters the evaporator 7 after being throttled by the throttling device 8, the refrigerant flowing in the evaporator 7 absorbs heat, the refrigeration effect is achieved, and the refrigerant flows out of the evaporator 7 and returns to the compressor 5.

When defrosting is performed, the electromagnetic valve 82 is opened; the refrigerant that is in the high-pressure gaseous state in the compressor 5 turns into the liquid refrigerant of high pressure after condenser 6, then the liquid refrigerant of high pressure is in directly entering into evaporimeter 7 through bypass pipeline 81, the refrigerant that enters into among the evaporimeter 7 is owing to not pass through throttling action of throttling arrangement 8, make the refrigerant temperature that flows among the evaporimeter 7 higher, in order to realize evaporimeter 7 by inside outside defrosting process, the defrosting effect is more thorough, simultaneously the temperature rise range in the storing cavity is less in the cabinet body 1, it is better to the save effect of goods, reduce the energy consumption.
