Description

Technical Field

[0001] This utility model relates to a refrigeration device, and more particularly to a compressor. Background Technology

[0002] Freezers are a common household appliance that uses a compressor circulation system for cooling. Typically, the compressor contains heat-generating components such as a motor stator, rotor, and compressor pump, which generate a lot of heat during operation. This results in significant energy loss for the compressor. In addition, the evaporator in the freezer compressor system produces condensate, which needs to be cleaned regularly to prevent overflow and accumulation inside the freezer.

[0003] In existing technologies, a drip tray is typically installed on the upper side of the compressor. This serves two purposes: firstly, to collect condensate, and secondly, to cool the compressor through heat exchange between the drip tray and the compressor, thereby reducing the compressor's heat load. However, because the condensate also undergoes indirect heat transfer between the condensate and the compressor casing through the drip tray, the heat transfer efficiency is low, resulting in an insignificant cooling effect. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an energy-saving compressor that reduces heat load.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A heat-reducing and energy-saving compressor includes a housing, with an upward-opening dam welded around the periphery of the housing. A water storage cavity for storing condensate is formed between the inner wall of the dam and the outer wall of the housing, and the top of the dam is lower than the top of the housing.

[0006] Compared to existing technologies, this application has a circumferentially welded dam portion on the outer side wall of the housing. A water storage cavity for storing condensate is formed between the inner wall of the dam portion and the outer wall of the housing. The condensate exchanges heat with the compressor, and the condensate can absorb heat to cool the compressor, reducing the compressor's heat load and thus reducing the freezer's energy consumption. In addition, the condensate is in direct contact with the surface of the compressor, and the heat generated by the compressor will cause the condensate to evaporate, which not only improves the cooling efficiency but also prevents the condensate from overflowing and remaining inside the freezer.

[0007] As a further improvement of this utility model, an overflow hole is provided at the upper part of the cofferdam.

[0008] As a further improvement of this utility model, the cofferdam part is a cone shape that expands outward at the upper end.

[0009] As a further improvement of this utility model, the housing is composed of an upper cover and a lower cover, and the lower end of the dam is welded to the lower cover.

[0010] As a further improvement of this utility model, the upper end of the lower cover is provided with an annular insertion groove along the circumferential edge. After assembly, the lower end of the upper cover is inserted into the insertion groove.

[0011] As a further improvement of this utility model, the upper cover and the inner wall of the insertion groove are connected by an interference fit, and the contact area between the upper cover and the inner wall of the insertion groove is coated with waterproof adhesive.

[0012] As a further improvement of this utility model, an electrical box is installed on the outer side wall of the lower cover by screws.

[0013] The beneficial effects of this utility model are as follows: This utility model has an upward-opening dam welded around the outer perimeter of the casing. The inner wall of the dam and the outer wall of the casing form a water storage cavity for storing condensate. The condensate exchanges heat with the compressor, and the condensate can absorb heat to cool the compressor, reducing the compressor's heat load and thus reducing the freezer's energy consumption. In addition, the condensate is in direct contact with the surface of the compressor, and the heat generated by the compressor will cause the condensate to evaporate, which not only improves the cooling efficiency but also prevents the condensate from overflowing and remaining inside the freezer.

[0014] The top of the dam section of this utility model is lower than the top of the casing, which allows for the modification of the original compressor structure by raising and lowering it. While maintaining the overall height, it adds the function of collecting condensate water to avoid installation space, making the structure compatible with traditional freezers without requiring significant adjustments to the original installation layout, thus reducing modification and application costs.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0021] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0022] Reference Figures 1 to 3 A heat-reducing and energy-saving compressor includes a housing. An upward-opening weir 3 is welded to the periphery of the housing. A water storage cavity 31 for storing condensate is formed between the inner wall of the weir 3 and the outer wall of the housing. The top of the weir 3 is lower than the top of the housing. In this invention, the condensate exchanges heat with the compressor, absorbing heat and cooling the compressor, thus reducing its heat load and lowering the refrigerator's energy consumption. Furthermore, the condensate is in direct contact with the compressor surface; the heat generated by the compressor evaporates the condensate, improving cooling efficiency and preventing overflow into the refrigerator.

[0023] The top of the dam section 3 of this utility model is lower than the top of the casing. It can be modified by raising and lowering the original compressor structure. While keeping the overall height unchanged, it adds the function of collecting condensate water to avoid installation space. This makes the structure compatible with traditional freezers without the need for major adjustments to the original installation layout, thus reducing the cost of modification and application.

[0024] An overflow hole 32 is provided on the upper part of the cofferdam 3. When too much condensate causes the water level in the storage chamber to reach the height of the overflow hole 32, the excess water can be discharged in time through the overflow hole 32. The overflow hole 32 can also be equipped with a drain pipe to facilitate drainage and improve safety.

[0025] The cofferdam 3 is a cone shape that expands outward at the top, forming a funnel shape that is wider at the top and narrower at the bottom. On the one hand, it facilitates the smooth flow of condensate into the water storage chamber 31; on the other hand, it can increase the contact area between the condensate in the water storage chamber and the side of the upper cover, thereby improving the heat exchange efficiency.

[0026] The housing consists of an upper cover 1 and a lower cover 2, with the lower end of the embankment 3 welded to the lower cover 2. In this embodiment, the upper end of the lower cover 2 is provided with an annular insertion groove 21 along its circumferential edge. After assembly, the lower end of the upper cover 1 is inserted into the insertion groove 21, resulting in a simple assembly structure.

[0027] The upper cover 1 and the inner wall of the insertion groove 21 are connected by an interference fit. Waterproof adhesive is applied to the contact area between the upper cover 1 and the inner wall of the insertion groove 21 to prevent condensate from flowing into the compressor.

[0028] An electrical box 4 is mounted on the outer wall of the lower cover 2 using screws. In this embodiment, the compressor contains commonly available components such as a motor stator, rotor, and compressor pump body, and the electrical box 4 is used for electrical connection with these components.
