Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated cabinets, in particular to an ice cream cabinet with an air outlet cold break structure. Background Art

[0002] An air-cooled ice cream cabinet is an ice cream storage and display device that uses air-cooled refrigeration technology. The air-cooled refrigeration technology blows the cold air inside the evaporator to the inside of the ice cream cabinet through a fan to achieve a fast and uniform cooling effect. However, the temperature inside the air-cooled ice cream cabinet usually maintains at a load temperature of -21 °C, and the air outlet temperature at the air outlet can reach as low as below -30 °C. Such a low temperature can easily cause condensation and icing problems on the upper and lower sides of the air outlet.

[0003] Currently, the air-cooled ice cream cabinets on the market usually add heating wires at the parts prone to icing to avoid condensation and icing problems. However, the cold generated by the air-cooled ice cream cabinet can still be transmitted through the sheet metal, resulting in energy loss. Summary of the Utility Model

[0009] Further, the first baffle is L-shaped and is connected to the second inner plate at the rear; the second baffle is L-shaped, is connected to the bottom of the first baffle at the front, and is connected to the first inner plate through a heat insulation plate at the rear.

[0010] Further, the second baffle includes a first connection section and a second connection section, and the included angle between the extension line of the first connection section and the extension line of the second connection section is 85°.

[0011] Further, the heat insulation plate has a plurality of oblong holes.

[0012] Further, the cold break part includes a sealed space, a first heat preservation and insulation block, and a second heat preservation and insulation block. The sealed space is formed by the gap between the first foaming cavity and the second foaming cavity.

[0024] Combined with Figure 1 and Figure 2 As shown, an ice cream cabinet with an air outlet cold interruption structure includes a housing 18, a base and a back plate. The base and the back plate are fixed inside the housing 18. The base is located at the lower side inside the housing 18 and is equipped with a refrigeration system. The back plate is located at the upper side inside the housing 18. The base has a first inner plate 1, a first outer plate 2 and an inner container. The first inner plate 1 is located between the first outer plate 2 and the inner container, and the inner container is located inside the first inner plate 1. The first inner plate 1 and the first outer plate 2 do not contact each other, and a first foaming cavity 3 is formed therebetween. A foaming layer is filled in the first foaming cavity 3. The inner container is fixedly connected to the first inner plate 1, and an air duct for cold air flow is formed between the side wall of the inner container and the first inner plate 1. The end of the air duct has an air outlet. The back plate includes a second inner plate 4 and a second outer plate 5. A second foaming cavity 6 is formed between the second inner plate 4 and the second outer plate 5. Foaming layers are filled in both the first foaming cavity 3 and the second foaming cavity 6.

[0025] As Figure 3 shown, the top plate of the air outlet includes a first baffle 7, a second baffle 10, an air outlet heat preservation plate 9 and a first heating wire 8. There is an accommodation cavity between the first baffle 7 and the second baffle 10. The air outlet heat preservation plate 9 and the first heating wire 8 are arranged in the accommodation cavity. The first heating wire 8 is located at the top of the air outlet heat preservation plate 9. The bottom of the air outlet heat preservation plate 9 is in close contact with the second baffle 10 to prevent the cold air at the air outlet from overflowing upwards. The first heating wire 8 cooperates with the air outlet heat preservation plate 9 to avoid the problem of condensation and icing on the top plate of the air outlet. The first baffle 7 is L-shaped and is fixedly connected to the second inner plate 4 at the rear. The second baffle 10 is L-shaped and includes a first connection section and a second connection section. The included angle between the extension line of the first connection section and the extension line of the second connection section is 85°, which is used to guide the cold air flow. The front part of the first connection section is fixedly connected to the bottom of the first baffle 7, and the lower part of the second connection section is fixedly connected to the first inner plate 1 through a heat insulation plate 17. The heat insulation plate 17 is L-shaped and has a plurality of long round holes on both sides, which is used to reduce the transfer of cold quantity. And the heat insulation plate 17 isolates between the first connection section and the first inner plate 1 to avoid direct contact and cold quantity transfer between the two.

A cold-breaking part is provided between the first foaming cavity 3 and the second foaming cavity 6. The cold-breaking part includes a sealed space 13, a first heat-insulating block 11, and a second heat-insulating block 12. The sealed space 13 is formed by the gap between the first foaming cavity 3 and the second foaming cavity 6. A sealing strip is provided between the first inner plate 1 and the second inner plate 4, and a sealing strip is also provided between the second outer plate 5 and the second outer plate 5. The sealed space 13 is filled with sealant. The first heat-insulating block 11 is arranged on the top of the first foaming cavity 3 to separate the first inner plate 1 from the first outer plate 2 and prevent the transfer of cold between sheet metal parts. The second heat-insulating block 12 is arranged at the bottom of the second foaming cavity 6 to separate the second inner plate 4 from the second outer plate 5 and prevent the transfer of cold between sheet metal parts. The first heat-insulating block 11 is located below the sealed space 13, and the second heat-insulating block 12 is located above the sealed space 13.
