Description

Technical Field

[0001] This utility model relates to the field of evaporators, and in particular to a centrally located evaporator for supermarket island display cases. Background Technology

[0002] Island display cases, also known as horizontal freezers, are generally used for the sale and display of frozen and refrigerated food. Depending on the usage scenario and design features, island display cases can be divided into several types, including traditional island display cases (small at the bottom and large at the top), flat glass display cases, combination display cases, large blast freezers, and island display cases used in supermarkets and shopping malls.

[0003] A search revealed a patent, such as Chinese Patent No. CN 217685968 U, which discloses a centrally located evaporator for a horizontal refrigerator used in supermarkets. This patent relates to the field of horizontal refrigerators for supermarkets and includes a device body. A top bridge is fixedly connected to the center of the top of the inner cavity of the device body. Fixing blocks are symmetrically arranged on the left and right sides of the bottom of the top bridge. A honeycomb mesh is symmetrically fixedly connected to one side of the inner cavity of the two fixing blocks. An air guide plate is fixedly connected to the bottom of the inner cavity of the back panel. Heating tubes are symmetrically fixedly connected to the left and right sides of the centrally located evaporator. A return air filter is fixedly connected to the bottom of the return air glass. A pad is provided at the bottom of the return air filter, and a fan is installed on the side of the pad. This invention, a centrally located evaporator for a horizontal refrigerator used in supermarkets, reduces the heat exchange between the centrally located evaporator and the outside environment by placing the centrally located evaporator in the middle of the inner cavity of the back panel. This reduces the power consumption of the device body, making the product more energy-efficient, easier to assemble, and increasing the space utilization of the device body.

[0004] However, the aforementioned centrally located evaporator for supermarket horizontal freezers, because it is installed in the center inside the freezer, not only takes up too much storage space, but also generates unnecessary noise due to the use of multiple fans for defrosting.

[0005] Therefore, it is essential to invent a centrally located evaporator for supermarket island display cases. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings: Example

[0029] Reference Figure 1-6A centrally located evaporator for a supermarket island display case includes an evaporator body and an island display case body 10, wherein the evaporator body is centrally and fixedly installed in the storage cavity of the island display case body 10;

[0030] In this embodiment, the evaporator body includes an annular shell 1, a base 2, an evaporation assembly 3, and an annular vent 4. The base 2 is detachably and fixedly installed at the bottom of the annular shell 1. The base 2 can support the evaporation assembly 3 and ensure the stability of the evaporation assembly 3 in the annular shell 1. The evaporation assembly 3 is coaxially and fixedly installed inside the annular shell 1 so that the annular shell 1 can protect the evaporation assembly 3. The annular vent 4 is detachably and fixedly installed at the opening at the top of the annular shell 1. The annular shell 1 and the annular vent 4 are exposed in the storage cavity of the island cabinet body 10 so that the cold air can be evenly delivered to the storage cavity of the island cabinet body 10 through the annular vent 4.

[0031] In this embodiment, a heating chamber 5 is coaxially provided on the annular shell 1. A heating wire 6 is fixedly installed in a spiral shape inside the heating chamber 5. When the evaporation component 3 needs to be defrosted, the annular shell 1 can be heated through the heating wire 6, which indirectly heats the evaporation component 3, thereby quickly defrosting the evaporation component 3 and ensuring quietness during the defrosting process.

[0032] In this embodiment, the evaporation assembly 3 includes annular fins 31 and evaporation tubes 32. Several annular fins 31 are provided, and several annular fins 31 are stacked and fixed together to form a cylindrical column. The evaporation tubes 32 are evenly wound around the cylindrical column formed by the annular fins 31 in order to increase the heat exchange area, better carry out heat exchange, improve refrigeration efficiency, and thus reduce energy consumption.

[0033] In this embodiment, a wiring hole is provided on one side of the bottom of the annular housing 1. The wiring hole is connected to the heating cavity 5. The heating wire control line 7 of the heating wire 6 passes through the wiring hole so that the heating wire control line 7 can be connected to the controller. The controller of the heating wire 6 is fixedly installed at the bottom of the island cabinet body 10.

[0034] In this embodiment, two notches 8 are evenly provided on the other side of the bottom of the annular shell 1. The liquid inlet pipe 35 and the liquid outlet pipe 36 of the evaporator pipe 32 pass through the corresponding notches 8 so that the liquid inlet pipe 35 and the liquid outlet pipe 36 can be connected to the compressor piping system of the island cabinet body 10.

[0035] In this embodiment, a number of annular fins 9 are uniformly arranged on the inner surface of the annular shell 1 from top to bottom, so that when the heating wire 6 heats the annular shell 1, the heat can be better transferred to the evaporator tube 32 through the annular fins 9.

[0036] In this embodiment, a conical cavity 21 is formed on the upper surface of the base 2 to collect the melted frost water on the evaporation tube 32. A through hole 22 is formed through the base 2 to allow for drainage and air supply. The through hole 22 is coaxially connected to the conical cavity 21 and the interior of the annular shell 1. A multi-purpose pipe 23 is fixedly installed on the bottom surface of the base 2 to allow for drainage and air supply. The multi-purpose pipe 23 is coaxially connected to the through hole 22. An air inlet pipe 24 is fixedly installed on one side of the multi-purpose pipe 23, and the air inlet pipe 24 is connected to the multi-purpose pipe 23. The air inlet pipe 24 can be connected to the air supply system of the island cabinet body 10, so that the air supply system can control the air volume delivered to the storage cavity of the island cabinet body 10 according to the usage environment, and achieve a rapid cooling effect when the temperature is high. The bottom end of the multi-purpose pipe 23 is fixedly installed with a drain pipe 25, which is connected to the multi-purpose pipe 23, so that the frost water melted on the evaporator pipe 32 can be discharged from the through hole 22 into the multi-purpose pipe 23, and then from the multi-purpose pipe 23 into the drain pipe 25.

[0037] In this embodiment, a solenoid valve 26 is fixedly installed on the drain pipe 25 so as to control the opening and closing of the drain pipe 25. The solenoid valve 26 is only opened during defrosting.

[0038] In this embodiment, several gaskets 33 are fixedly installed between each pair of adjacent annular fins 31 to create a certain space between the two adjacent annular fins 31, so as to allow better air circulation. Several holes 34 are opened through each annular fin 31 to allow better air circulation and increase the heat exchange area.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
