DETAILED DESCRIPTION

[0036] The present invention is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0037] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. It occupies an important position in people's lives and brings many conveniences to people's lives. At present, there are many types and brands of refrigerators, which makes it possible for consumers to choose from many refrigerator products. How to win the favor of consumers and improve product competitiveness. Among refrigerator products with similar functions or performance, the lower the energy consumption of the refrigerator, the more attractive it is to consumers. Therefore, how to reduce the energy consumption of refrigerators has become an issue that refrigerator manufacturers pay more and more attention to.

[0038] At present, refrigerators usually use evaporators for refrigeration. During the operation of the evaporator, frost easily condenses on the refrigerant pipe, which affects the heat exchange area of ​​the evaporator and further affects the refrigeration effect of the evaporator.

[0039] In the related art, the automatic defrosting function of the refrigerator for the evaporator mostly uses the heat emitted by the heater arranged on the evaporator when it is working to achieve the purpose of defrosting. However, due to its own structural limitations, the existing heater is generally installed at the bottom of the evaporator. During the defrosting process, the heat of the heater is slowly transferred from the bottom to the top, which not only causes uneven defrosting, but also takes a long time to heat and has low defrosting efficiency, resulting in greater fluctuations in the temperature of the food stored in the refrigerator and more power consumption.

[0040] To solve the problems of uneven defrosting, low defrosting efficiency, high energy consumption, etc., refer to Figures 1 to 2As shown, this embodiment provides a refrigerator 200, in which an evaporator 100 capable of automatic defrosting is arranged. The evaporator 100 has a large heating area and uniform heat transfer, so as to achieve uniform defrosting, save heating time required for defrosting, have high defrosting efficiency, reduce energy consumption of the refrigerator, and reduce temperature fluctuation of food stored in the refrigerator 200, thereby improving food storage effect and making it cleaner and healthier. The refrigerator 200 in this embodiment can bring people a better use experience and improve product competitiveness.

[0041] Furthermore, the present embodiment also provides an evaporator 100, which is applied to the refrigerator 200. The evaporator 100 of the present embodiment can increase the defrosting area, improve the uniformity of defrosting, save the heating time required for defrosting, improve the defrosting efficiency, and reduce energy consumption. At the same time, by removing the frost layer to promote the heat exchange between the evaporator 100 and the outside, the refrigeration efficiency of the evaporator 100 is improved, and the refrigeration effect of the refrigerator 200 is improved. The compactness of the structure of the evaporator 100 can also be improved to save the space occupied by the evaporator 100 during packaging, transportation and installation.

[0042] See also Figures 3 to 5 As shown, the evaporator 100 in this embodiment includes a refrigerant pipe 130, a supporting assembly, and a heating assembly.

[0043] Refrigerant can flow through the refrigerant pipe 130 . When the evaporator 100 is in a cooling mode, air passes through the refrigerant pipe 130 and is discharged after being cooled by the refrigerant, thereby achieving cooling.

[0044] The support assembly includes a first support member 110 and a second support member 120 spaced apart from the first support member 110 along a first direction, the first direction being the X direction in the figure. The first support member 110 and the second support member 120 are respectively connected to two sides of the refrigerant pipe 130 spaced apart from each other along the first direction.

[0045] The heating assembly includes a first heating element 140 fixed to the first support element 110 and a second heating element 150 fixed to the second support element 120 .

[0046] When the evaporator 100 in this embodiment is defrosted, the first support member 110 and the second support member 120 are respectively arranged at intervals on both sides of the refrigerant pipe 130, the first heating member 140 is fixed to the first support member 110, and the second heating member 150 is fixed to the second support member 120, so that the first heating member 140 and the second heating member 150 start heating from opposite sides of the refrigerant pipe 130, which can increase the heating area of ​​the refrigerant pipe 130 and improve the uniformity of heat transfer to make defrosting uniform, and can also save heating time and improve defrosting efficiency, so that the frost layer attached to the refrigerant pipe 130 can be removed to promote the heat exchange between the refrigerant pipe 130 and the outside world, so as to improve the refrigeration efficiency of the evaporator 100. In addition, the structure of the evaporator 100 can be made compact, saving the space occupied by the evaporator 100 during packaging, transportation and installation.

[0047] Furthermore, since the outer side of the refrigerant tube 130 of the evaporator 100 has a large contact surface with the outside during the refrigeration process, it is easier for the water vapor in the air to condense into frost and cover the outer side of the refrigerant tube 130, making the frost layer on the outer side of the refrigerant tube 130 intersecting with the inner frost layer of the refrigerant tube 130 thicker and more stubborn. Based on this, the evaporator 100 in this embodiment can heat and defrost the refrigerant tube 130 from both sides of the refrigerant tube 130, so that the heat is gradually transferred from the outer side of the refrigerant tube 130 to the inner side of the refrigerant tube 130, while eliminating the inner frost layer of the refrigerant tube 130, it is more conducive to eliminating the thicker and more stubborn frost layer at the outer side of the refrigerant tube 130, further improving the defrosting effect, making the defrosting more thorough, and avoiding the residual frost layer.

[0048] See also Figures 3 to 5 As shown, in order to further improve the defrosting effect of the evaporator 100 while avoiding affecting the refrigeration effect of the evaporator 100. In this embodiment, the first support member 110 is provided with a first mounting surface 111 on the side wall facing the second support member 120, and the first mounting surface 111 is used to cover the first side of the refrigerant pipe 130. The second support member 120 is provided with a second mounting surface 121 on the side wall facing the first support member 110, and the second mounting surface 121 is used to cover the second side of the refrigerant pipe 130. Optionally, the first side and the second side of the refrigerant pipe 130 are spaced along the X direction in the figure.

[0049] The first heating element 140 is fixed to the first mounting surface 111, and the second heating element 150 is fixed to the second mounting surface 121. Optionally, in this embodiment, in order to facilitate the installation of the heating assembly on the support assembly, in this embodiment, the first heating element 140 and the second heating element 150 can be fixed to the support assembly by gluing or inlaying.

[0050] When the evaporator 100 in this embodiment is defrosted, the heat of the first heating element 140 is transferred in the opposite direction of X, and the heat of the second heating element 150 is transferred in the X direction, so that the first heating element 140 and the second heating element 150 are heated from the opposite sides of the refrigerant pipe 130, and the heat on both sides is transferred to the middle of the refrigerant pipe 130, which can increase the heating area of ​​the refrigerant pipe 130, save heating time, and improve defrosting efficiency, and can also prevent the heat from diffusing to the outside of the refrigerant pipe 130 during defrosting, affecting the temperature changes of the external environment, such as affecting the refrigeration temperature of the storage room in the refrigerator 200, affecting the food storage effect.

[0051] In one embodiment, in order to further improve the defrosting efficiency and make the defrosting more thorough, in this embodiment, the heating assembly includes a third heating member 160, and the third heating member 160 is connected between the first support member 110 and the second support member 120, so that the third heating member 160 covers the third side of the refrigerant pipe 130.

[0052] Optionally, in this embodiment, the third side of the refrigerant pipe 130 may be one of the two sides spaced apart along the Z direction in the figure, or may be one of the two sides spaced apart along the Z direction in the figure. Figure 1 From the outside Figure 1 That is, the third heating member 160 may cover the upper side or the lower side of the refrigerant tube 130 in the figure, or the third heating member 160 may cover the front side or the rear side of the refrigerant tube 130 in the figure.

[0053] When the evaporator 100 in this embodiment is in use, the first heating element 140, the second heating element 150 and the third heating element 160 can heat the refrigerant pipe 130 for defrosting at the same time, which further increases the heating area of ​​the refrigerant pipe 130, improves the defrosting efficiency, and eliminates the stubborn frost layer on the outside of the refrigerant pipe 130, thereby improving the defrosting effect.

[0054] In one embodiment, after the evaporator 100 is installed in the refrigerator 200, considering the compactness of the structure of the refrigerator 200, the assembly space of the evaporator 100 is limited. In order to facilitate the installation of the third heating element 160 in the assembly space of the evaporator 100, the defrosting efficiency can be further improved. In this embodiment, the side wall of the first support member 110 facing the refrigerant pipe 130 is provided with a third mounting surface 112, and the first mounting surface 111 and the third mounting surface 112 are arranged in sequence along the second direction. The second direction is the Z direction. The side wall of the second support member 120 facing the refrigerant pipe 130 is provided with a fourth mounting surface 122, so that the second mounting surface 121 corresponds to the first mounting surface 111, and the fourth mounting surface 122 corresponds to the third mounting surface 112. The third heating element 160 is connected between the third mounting surface 112 and the fourth mounting surface 122.

[0055] Optionally, the plane where the third heating element 160 is located is perpendicular to the length direction of the first supporting element 110 .

[0056] That is, in this embodiment, the heating assembly is fixed on the supporting assembly, the first heating element 140 and the second heating element 150 are fixed on both sides of the refrigerant tube 130, and the third heating element 160 is fixed on the lower side of the refrigerant tube 130 in the figure to save assembly space for other parts. In this embodiment, when the evaporator 100 is in use, the heat of the first heating element 140 is transferred along the X reverse direction, the heat of the second heating element 150 is transferred along the X direction, and the heat of the third heating element 160 is transferred along the Z direction to increase the heating area of ​​the refrigerant tube 130 and improve the defrosting efficiency.

[0057] In one of the embodiments, in order to facilitate heat exchange between the refrigerant pipe 130 and the outside air to accelerate the cooling effect, the evaporator 100 is usually provided with an air inlet and an air outlet, and the air volume is blown into the air inlet by the fan to cool down the refrigerant pipe 130 and then blown out through the air outlet to achieve cooling. In this embodiment, in order to prevent the heating component from hindering the cooling of the evaporator 100, the third heating element 160 is set as a tubular structure with a gap, so that the third heating element 160 can be installed at the air inlet position of the refrigerant pipe 130, which can achieve heating and defrosting of the refrigerant pipe 130 at the air inlet position in the defrost mode, so as to increase the heating surface of the refrigerant pipe 130 and improve the defrost efficiency, and can also not hinder the cooling effect of the evaporator 100 in the cooling mode.

[0058] It should be noted that the refrigeration and defrosting of the evaporator 100 are two independent operation processes. That is, in the refrigeration mode, the defrosting operation is not performed to prevent the heat generated by the heating component from affecting the refrigeration effect. Correspondingly, in the defrosting mode, the refrigeration operation is not performed to prevent the refrigeration temperature from affecting the defrosting effect.

[0067] The fourth clamping portion 124 includes a third groove 124a and a fourth groove 124b with openings facing each other, which are respectively arranged on two sides of the fourth mounting surface 122 extending along the second direction. That is, the opening of the third groove 124a faces the X direction, and the opening of the fourth groove 124b faces the opposite X direction.

[0068] In this embodiment, when the third heating element 160 is connected to the supporting assembly, one heating tube is placed in the first groove 114a and the third groove 124a, and the other heating tube is placed in the second groove 114b and the fourth groove 124b, so that the two heating tubes are spaced apart.

[0069] In one embodiment, the heating area of ​​the refrigerant pipe 130 is further increased to improve the defrosting efficiency, shorten the heating time, and save energy. Meanwhile, the refrigeration effect of the refrigerant pipe 130 of the evaporator 100 is not hindered.

In this embodiment, steel pipe heating wires are also arranged at the air inlet and the air outlet of the shell body.
