DETAILED DESCRIPTION
[0037] The present invention will be described in detail below in conjunction with the specific implementation modes or embodiments shown in the accompanying drawings. However, these implementation modes or embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person of ordinary skill in the art based on these implementation modes or embodiments are all included in the protection scope of the present invention.
[0038] like Figure 1 and Figure 2 As shown, the present invention provides an evaporator assembly, which is easy to assemble, firmly connected, and is provided with a wind shield, which can effectively reduce the amount of hot air (air leakage) that does not pass through the evaporator fins and improve the refrigeration efficiency of the evaporator.
[0039] The assembly includes an evaporator 100 and a first fixing member 200 disposed on one side of the evaporator 100. The evaporator 100 includes fins 110 and fin tubes 120 connected to the fins. Figure 3 and Figure 4 As shown, the first fixing member 200 includes a first bottom plate 210, a first buckle portion 220 and a first wind shielding portion 230, wherein:
[0040] The first bottom plate 210 includes a fixing portion, through which one side of the first bottom plate 210 can be fixedly connected to the refrigerator liner 500. The first snap-fit portion 220 is snap-fitted to the matching opening on the fin 110, so that the first fixing portion 200 is fixedly connected to the evaporator 100. This snap-fit connection method is simple to operate, but the connection is highly secure. The first wind shield 230 protrudes from the other side of the first bottom plate 210, and the end surface of the first wind shield 230 away from the first bottom plate 210 conflicts with the evaporator cover 400. Figure 7 As shown, the hot air in the refrigerator moves from the bottom of the evaporator 100 to the return air port 410 of the cover plate 400. Due to the first wind shield 230, the hot air cannot pass directly from the side of the evaporator 100, but must flow to the fins 110 of the evaporator 100. Figure 7 direction of the arrow, thereby improving the cooling efficiency of the evaporator.
[0041] It should be noted that Figure 3 yes Figure 1 An enlarged view of the first fixing member 200, Figure 4 yes Figure 2 FIG. 2 is an enlarged view of the first fixing member 200.
[0042] Continue to refer Figures 1 to 4In a preferred embodiment, the fin tube 120 includes a U-shaped portion 121 protruding from the fin, and the first wind shield 230 includes a curved surface 231 that matches the U-shaped portion 121 of the fin tube. The curved surface matches the U-shaped portion, which can increase the connection firmness between the evaporator and the first fixing member. At the same time, the curved surface 231 also has the effect of guiding wind. The hot air flowing from the bottom of the side of the evaporator 100 is guided by the curved surface 231 to flow to the middle of the evaporator, thereby further improving the refrigeration efficiency of the evaporator. Furthermore, one side of the curved surface 231 of the first wind shield 230 conflicts with the fin 110 of the evaporator 100, and the other side conflicts with the side of the evaporator cover 400, thereby further reducing the air leakage and improving the refrigeration efficiency of the evaporator.
[0043] Continue to refer Figure 3 and Figure 4 In a preferred embodiment, the first buckle portion 220 includes a first buckle member 221 and a second buckle member 222 with opposite buckle surfaces. The buckle surfaces of the first buckle member 221 and the second buckle member 222 are hook-shaped, and the two oppositely arranged hook-shaped buckle surfaces (the buckle surfaces can be arranged opposite to each other, or can be arranged like Figure 3 and Figure 4 The first fixing member 200 and the evaporator 100 are arranged opposite to each other in this way, which can further increase the connection firmness between the first fixing member 200 and the evaporator 100. Furthermore, the first fastener 221 is arranged on the first bottom plate 210, and the second fastener 222 is fixedly connected to the first bottom plate 210 through the arc-shaped connecting portion 223. The first fastener 221 and the second fastener 222 are not on the same plane, and with the oppositely arranged fastener surfaces, the connection firmness between the first fixing member 200 and the evaporator 100 can be further increased. At the same time, the arc-shaped connecting portion 223 can well match the U-shaped portion 121 of the fin tube 120.
[0044] In the prior art, the evaporator assembly is generally installed on the inner tank by means of screws. This method is simple to install and has a high degree of connection firmness. However, this installation method requires a through hole to be set on the inner tank, which will cause "overflow" (i.e., water leakage) in the inner tank. Therefore, in order to prevent overflow, the place where the evaporator assembly needs to be installed in the inner tank is generally marked. However, with this method, the workers may have inconsistent installation positions of the evaporator assembly during installation (during hundreds or thousands of assembly processes, the workers' punching positions may deviate from the marked positions), thereby affecting the consistency of the evaporator's refrigeration performance (i.e., some have good refrigeration effects, while some have poor refrigeration effects). To solve the above problems, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 8In a preferred embodiment, the fixing portion of the first bottom plate 210 is a through hole 211, which is used to fix the first bottom plate 210 with the refrigerator liner 500 by screws. At the same time, a positioning portion 212 is provided on the side where the first bottom plate 210 is connected to the refrigerator liner 500. The positioning portion 212 is generally a convex portion or a concave portion, and the refrigerator liner 500 is provided with a corresponding concave portion or convex portion, preferably as shown in FIG. Figure 4 As shown, the positioning portion 212 is a cylindrical protrusion, and the inner tank 500 is provided with a corresponding recessed portion. Through the positioning portion 212, the position of the evaporator installed on the inner tank is fixed, so that the refrigeration performance of the evaporator installed by this process can be kept consistent.
[0045] In order to further improve the connection firmness between the evaporator assembly and the refrigerator liner and reduce the air leakage, in a preferred embodiment, the evaporator assembly further includes a second fixing member 300 disposed on the other side of the evaporator 100. Figure 5 and Figure 6 As shown (it should be noted that Figure 5 yes Figure 1 An enlarged view of the second fixing member 300, Figure 6 yes Figure 2 The second fixing member 300 includes a second bottom plate 310, a second buckle portion 320, a second wind shield portion 330 and a second connecting portion 340.
[0046] The second base plate 310 is fixedly connected to the refrigerator liner, and the connection structure can refer to the through hole and positioning part of the first base plate 210. The second buckle part 320, the second wind shield part 330 and the second connecting part 340 are arranged on the side of the second base plate away from the refrigerator liner. The structure of the second buckle part 320 can refer to the first buckle part 220, which is used to be buckled with the opening of the fin of the evaporator. One side of the second wind shield part 330 is connected to the second base plate 310 through the second connecting part 340, and the other side is in conflict with the evaporator cover plate 400, thereby blocking part of the air leakage. The second wind shield part 330, the second connecting part 340, the second base plate 310 and the evaporator 100 together form a wiring cavity 350 for the evaporator and other electrical wires.
[0047] Furthermore, a cover plate mounting portion 360 is provided on a side of the second connecting portion 340 of the second fixing member 300 away from the evaporator 100. The cover plate mounting portion 360 can block wind and facilitate the installation of the cover plate (the edge of the cover plate mounting portion is used for blocking wind, and the concave portion in the middle cooperates with the convex portion of the cover plate for installation).
[0048] like Figure 1 and Figure 2As shown, in a specific embodiment, the evaporator assembly includes an evaporator 100, a first fixing member 200 and a second fixing member 300 disposed on both sides of the evaporator 100. The evaporator 100 includes a fin 110 and a fin tube 120, and the fin tube 120 includes a U-shaped portion 121 protruding from the fin.
[0049] The first fixing member 200 includes a first bottom plate 210, a first buckle portion 220 and a first wind shield portion 230. The first bottom plate 210 includes a through hole 211 and a positioning portion 212 connected to the inner tank 500 with screws. The first buckle portion 220 includes a first buckle 221 and a second buckle 222 which are not in the same horizontal plane and have hook-shaped buckle surfaces arranged oppositely (the hook-shaped buckle surface can be buckled with the opening on the fin 110). The first buckle 221 is arranged on the first bottom plate 210, and the second buckle 222 is fixedly connected to the first bottom plate 210 through an arc-shaped connecting portion 223. The first wind shield portion 230 includes an arc surface 231 that matches the U-shaped portion 121 of the fin tube 120. The bottom end of the arc surface 231 is connected to the first bottom plate, the top end is in conflict with the evaporator cover plate 400, one side of the arc surface 231 is in conflict with the fin 110 of the evaporator 100, and the other side is in conflict with the side of the evaporator cover plate 400. The arc surface 231 and the arc-shaped connecting portion 223 cooperate to form an outward eight-shaped shape, which can be embedded between the two U-shaped portions 223, thereby increasing the connection firmness between the first fixing member and the evaporator.
[0050] The second fixing member 300 includes a second base plate 310, a second buckle portion 320, a second windshield portion 330 and a second connecting portion 340. The structures of the second base plate 310 and the second buckle portion 320 can refer to the structures of the first base plate 210 and the first buckle portion 220 respectively. However, since the second fixing member needs to increase the wiring cavity, the second windshield portion 330 is different in structure from the first windshield portion 230. One side of the second windshield portion 330 is connected to the second base plate 310 through the second connecting portion 340, and the other side is in conflict with the evaporator cover plate 400, thereby blocking part of the air leakage. At the same time, the second windshield portion 330, the second connecting portion 340, the second base plate 310 and the evaporator 100 are surrounded to form a wiring cavity 350 for electrical wires such as the evaporator. In addition, a cover plate mounting portion 360 is provided on the side of the second connecting portion 340 of the second fixing member 300 away from the evaporator 100.
[0051] The evaporator assembly of the present invention is easy to assemble, firmly connected, and is provided with a wind shield, which can effectively reduce the amount of hot air (air leakage) that does not pass through the evaporator fins and improve the refrigeration efficiency of the evaporator. At the same time, the position of the evaporator assembly installed on the inner tank is fixed, thereby ensuring that the refrigeration performance of the evaporator can remain consistent.
[0052] The present invention further provides a refrigerator, comprising an inner container 500, an evaporator cover plate 400 and the evaporator assembly described in any of the above solutions.
[0053] In a preferred embodiment, the evaporator assembly includes a first fixing member 200 and a second fixing member 300, and the evaporator cover plate 400 is provided with a return air outlet 410, the first fixing member 200 and the second fixing member 300 are respectively arranged at both ends of the evaporator 100, and the first fixing member 200 and the second fixing member 300 are arranged on one side of the return air outlet 410 close to the evaporator cover plate 400.
[0054] In another preferred embodiment, a positioning portion 212 is provided on one side of the first bottom plate 210 of the first fixing member 200 close to the inner container 500 , and a groove matching with the positioning portion 212 is provided on the inner container 500 .
