Description

Technical Field

[0001] This utility model relates to the field of freezer technology, and in particular to defrosting and energy-saving freezers. Background Technology

[0002] The aforementioned freezers include refrigerators, display cases, order counters, medicine cabinets, and other cabinets that use compressors for refrigeration, allowing stored items to be preserved at low temperatures.

[0003] The refrigerator includes a refrigerator body, which in turn includes a cabinet and a refrigeration system. The refrigeration system includes a compressor, a condenser, a capillary tube, an evaporator, and a compressor connected in sequence by pipes. The cabinet has a storage cavity and a condensation space. The storage cavity is the space for storing and cooling items, and the condensation space is the space for installing the compressor and condenser. The evaporator is a coiled pipe installed on the side wall of the storage cavity. Its function is to transfer the heat inside the refrigerator to the external environment by absorbing heat through the evaporation of the refrigerant. The low-temperature, low-pressure liquid refrigerant absorbs heat from the medium being cooled (such as air or liquid) during the evaporation process, thereby reducing the internal temperature of the refrigerator and achieving cooling or maintaining a low-temperature environment.

[0004] During the operation of the evaporator, frost and ice will form on the outside of the evaporator. A thick layer of ice will affect the cooling effect, so it is necessary to remove this ice layer regularly or irregularly. The technical solution adopted is to install a heating element connected to a power source under the evaporator. When defrosting is needed, the heating element is powered on, and the heat generated by the heating element melts the ice on the evaporator into water. This water is called ice melt water. The ice melt water flows down and leaves the evaporator. In order to facilitate the smooth discharge of ice melt water, a water collection tank is installed under the evaporator, and there is a drain hole on the side of the cabinet. The water collection tank passes through the drain hole to discharge the ice melt water outside the cabinet.

[0005] In the existing technology, the heating tube is installed under the water tank and is exposed, meaning the heating tube is exposed inside the cabinet. This has the disadvantages that the heat generated by the heating tube is easily dissipated inside the cabinet, the evaporator has low efficiency in receiving the heat generated by the heating tube, and it also results in low defrosting efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned shortcomings by providing a refrigerator that reduces heat waste from the heating element and has high defrosting efficiency—a defrosting energy-saving refrigerator.

[0007] The technical solution adopted by this utility model is as follows: a defrosting energy-saving freezer includes a freezer body, which in turn includes a cabinet and a refrigeration system. The refrigeration system includes a compressor, a condenser, a capillary tube, an evaporator, and a compressor connected in sequence by pipes. The cabinet has a storage cavity and a condensation space. The storage cavity is a space for storing and cooling items, and the condensation space is a space for installing the compressor and condenser. The evaporator is a coiled pipe installed on the side wall of the storage cavity. A heating element connected to a power source is installed below the evaporator, and a water collection trough is installed below the steam. A drain hole is provided on the side of the cabinet, and the water collection trough passes through the drain hole to discharge melted ice water outside the cabinet. The feature is that a partition is installed above the water collection trough, and the side of the partition has multiple drain holes leading to the water collection trough. A receiving cavity is formed below the partition and above the water collection trough, and the heating element is installed inside the receiving cavity.

[0008] Furthermore, the cross-section of the partition is an "N" shaped structure.

[0009] Furthermore, the partition has screw holes, which are partition screw holes, and there are plastic cards that hold the heating tube in place. These cards also have screw holes, which are card screw holes. The cards are connected together by bolts through the card screw holes and the partition screw holes.

[0010] The beneficial effects of this invention are: such a freezer has the advantages of reducing heat waste generated by the heating element and high defrosting efficiency. Attached Figure Description

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] like Figure 1 , 2 As shown in Figures 3 and 4, a defrosting energy-saving freezer includes a freezer body, which in turn includes a cabinet 1 and a refrigeration system 2. The refrigeration system includes a compressor 21, a condenser 22, a capillary tube 23, an evaporator 24, and a compressor connected in sequence by pipes. The cabinet has a storage cavity 11 and a condensation space 12. The storage cavity is a space for storing and cooling items, and the condensation space is a space for installing the compressor and condenser. The evaporator is a coiled pipe installed on the side wall of the storage cavity. A heating element 3 connected to a power source is installed below the evaporator, and a water collection trough 4 is installed below the evaporator. A drain hole 13 is located on the side of the cabinet. The water collection trough passes through the drain hole to drain melted ice water outside the cabinet. The feature is that a partition 5 is installed above the water collection trough. The side of the partition has multiple drain holes 51 leading to the water collection trough. The partition and the water collection trough together form a receiving cavity 52, and the heating element is installed inside the receiving cavity.

[0018] With the above-mentioned configuration of this utility model, the heat generated by the heating tube is generally confined within the receiving cavity, which reduces the diffusion of heat from the exposed part below the heating tube. The heat rises through the partition and heats the evaporator, which can melt the ice on the evaporator, thus achieving the purpose of this utility model.

[0019] In one technical solution, the receiving cavity is an upwardly convex structure, and the heating tube is located inside the convex structure. This design ensures that the convex structure covers the heating tube, preventing melted ice water from dripping onto it.

[0020] In one technical solution, the water receiving tank has a heat insulation layer underneath.

[0021] This design also reduces the waste of heat generated by the heating element that passes through the water tank.

[0022] Furthermore, the partition has an "N"-shaped cross-section and is welded to the water receiving tank.

[0023] Furthermore, the partition has screw holes, which are partition screw holes, and there is a plastic card 6 that holds the heating tube. The card has screw holes, which are card screw holes 61. The card is connected by a bolt 7 through the card screw holes and the partition screw holes.

[0024] This design also provides the advantage of a strong connection.

[0025] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
