[0002] A cushion block is usually arranged at the bottom of the evaporator of a heat pump. The cushion block is made of rubber material and is used to raise the evaporator to prevent the bottom of the evaporator from soaking in water and frosting. At the same time, the cushion block can also protect the evaporator from being worn through the copper pipe by the sheet metal of the shell bottom plate during transportation.
[0003] However, in the prior art, the cushion block of the evaporator is an integral rubber block, which results in too large contact area between the cushion block and the evaporator, and further causes problems such as water accumulation and frosting.
[0004] Therefore, there is an urgent need for a cushion block for an evaporator and a heat pump to solve the above problems. Summary of the Utility Model
[0005] One of the technical problems solved by the utility model is to provide a cushion block for an evaporator, which can effectively solve the problems of large contact area between the cushion block and the evaporator, leading to water accumulation and frosting. The contact area between the cushion block body and the evaporator is smaller and it is convenient for water to drain out, avoiding frosting.

In addition, both ends of the water guide groove penetrate through the side wall of the cushion block body, which can effectively drain the accumulated water between the cushion block body and the bottom surface of the evaporator, and thus effectively avoid the problem of frosting and ensure the heat transfer effect of the evaporator.
[0012] In one embodiment, the water guide groove is arranged at an angle with the fins of the evaporator; the angle is set to be 40° - 50°.
[0013] In one embodiment, the cushion block body is provided with a drainage hole penetrating along the thickness direction.
[0014] In one embodiment, the depth of the water guide groove is not greater than half of the thickness of the cushion block body.
[0015] In one embodiment, a connecting protrusion is arranged on one side wall of the cushion block body, and a connecting groove is arranged on the opposite side wall. The connecting protrusion can be connected with the connecting groove of another cushion block body.
[0016] In one embodiment, a buckle is arranged on the bottom surface of the cushion block body, and the buckle is used for clamping connection with the bottom plate of the shell.
[0017] In one embodiment, a clamping groove is arranged on the outer circumferential wall of the buckle.
[0018] The above second technical problem is solved by the following technical solution:

[0041] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0042] As Figures 1-6 shown, this implementation mode provides a cushion block for an evaporator. The cushion block for the evaporator is arranged between the evaporator 210 and the shell bottom plate 220. The cushion block for the evaporator includes a cushion block body 100. A water guide groove 110 is arranged on the top surface of the cushion block body 100, and both ends of the water guide groove 110 penetrate through the side wall of the cushion block body 100.
[0043] By arranging the cushion block body 100 between the evaporator 210 and the shell bottom plate 220 to raise the evaporator 210, on the one hand, it avoids the bottom of the evaporator 210 from being soaked in water, and on the other hand, it reduces the wear of the steel pipe of the evaporator 210 by the sheet metal of the shell bottom plate 220 during the transportation of the evaporator 210. At the same time, a water guide groove 110 is arranged on the top surface of the cushion block body 100, and the top of the water guide groove 110 is used to abut against the bottom surface of the evaporator 210. By arranging the water guide groove 110, the contact area between the cushion block body 100 and the bottom surface of the evaporator 210 is reduced. In addition, both ends of the water guide groove 110 penetrate through the side wall of the cushion block body 100, which can effectively drain the accumulated water between the cushion block body 100 and the bottom surface of the evaporator 210, thereby effectively avoiding the problem of frosting and ensuring the heat transfer effect of the evaporator 210.
[0044] Exemplarily, the cushion block body 100 is made of rubber material, which is easy to process and has better shock absorption effect, reducing the wear on the copper pipe of the evaporator 210.
[0045] Preferably, as Figure 1 and Figure 2 shown, the water guide groove 110 is arranged at an angle with the fin 211 of the evaporator 210. By setting it like this, when the evaporator 210 is placed on the cushion block body 100, the force between the top of the water guide groove 110 and the fin 211 of the evaporator 210 is more uniform, which is beneficial to improving the service life of the cushion block body 100; Exemplarily, the angle is set to 40° - 50°. In this embodiment, the cushion block body 100 is generally set as a rectangle, and the angle between the water guide groove 110 and the edge of the rectangular cushion block body 100 is set to 45°.
[0046] In this embodiment, a drainage hole 140 is arranged through the cushion block body 100 in the thickness direction. By arranging the drainage hole 140, it is used to directly drain the water in the water guide groove 110 below the cushion block body 100, which is beneficial to accelerating the drainage speed of the accumulated water. It can be understood that the drainage hole 140 is at least partially communicated with the bottom of the water guide groove 110. Optionally, the cross-section of the water guide groove 110 is set as a rectangle. In other embodiments, the cross-section of the water guide groove 110 can also be set as an arc, which is not specifically limited here.
[0047] It is worth noting that the depth of the water guide groove 110 is not greater than half of the thickness of the cushion block body 100. On the one hand, it can ensure that the side wall of the water guide groove 110 is not too high, reducing the possibility of deformation failure when supporting the evaporator 210; on the other hand, it can ensure that there is a certain thickness between the bottom of the water guide groove 110 and the bottom surface of the cushion block body 100 to play a role in supporting and damping the evaporator 210.
[0048] In one embodiment, more than two spacer bodies 100 are arranged adjacent to each other, that is, multiple spacer bodies 100 can be spliced and used to adapt to the evaporator 210 with different numbers of bent rows 212, improving the applicable positions and scenarios of the spacer bodies 100. At the same time, the number of spacers with various sizes and models is reduced, and the design and mold opening costs are reduced.
[0049] Specifically, to achieve the reliability of splicing between two spacer bodies 100, as Figure 3 and Figure 4 shown, a connecting protrusion 121 is provided on one side wall of the spacer body 100, and a connecting groove 122 is provided on the opposite side wall. The connecting protrusion 121 can be connected to the connecting groove 122 of another spacer body 100. The shapes of the connecting protrusion 121 and the connecting groove 122 are adapted to each other, and the connection method can adopt interference connection, snap connection, bonding, etc.
[0050] Furthermore, more than two connecting protrusions 121 and connecting grooves 122 are both arranged at intervals along the length direction of the spacer body 100, making the connection between the two more firm in the length direction of the spacer body 100.
[0051] In this embodiment, as Figure 5 and Figure 6 shown, a buckle 130 is provided on the bottom surface of the spacer body 100. The buckle 130 is used for snap connection with the shell bottom plate 220 to realize the connection between the spacer for the evaporator and the shell bottom plate 220. The connection between the spacer for the evaporator and the shell bottom plate 220 by snap connection is more convenient and reliable. In other embodiments, the connection between the spacer for the evaporator and the shell bottom plate 220 can also be realized by bonding or screwing.
[0052] Optionally, a clamping groove 131 is provided on the axial side wall of the buckle 130. When snap-connected, the shell bottom plate 220 can be placed in the clamping groove 131, with a simple structure and reliable snap connection.
[0053] As Figures 7-10 shown, this embodiment also discloses a heat pump, including a shell and an evaporator 210 arranged in the shell. The shell includes a shell bottom plate 220, and the spacer for the evaporator as described in any of the above solutions is arranged between the evaporator 210 and the shell bottom plate 220. For the heat pump provided with the above-mentioned spacer for the evaporator, it is beneficial to drain the accumulated water between the spacer body 100 and the bottom surface of the evaporator 210, avoiding the problem that the heat transfer effect of the evaporator 210 is poor due to the accumulated water frosting, and making the heat exchange efficiency of the heat pump higher and more stable.
[0054] Preferably, more than two spacer bodies 100 are arranged between the evaporator 210 and the shell bottom plate 220, and the water guide grooves 110 of two adjacent and abutting spacer bodies 100 are arranged in a through manner, so that the accumulated water can be smoothly drained through the through water guide grooves 110.
[0055] Further, in order to cooperate with the buckle 130 provided on the bottom surface of the cushion block body 100, the card hole 221 is correspondingly provided on the shell bottom plate 220, and the buckle 130 can be placed in the card hole 221 to realize the clamping connection with the shell bottom plate 220. Specifically, the width of the card slot 131 is adapted to the thickness of the shell bottom plate 220, so that the edge of the card hole 221 can be placed in the card slot 131 of the buckle 130 to achieve a reliable connection.
[0056] It is worth noting that the width of the cushion block body 100 is adapted to the thickness of each bent row 212 of the evaporator 210. As Figure 7 and Figure 8 shown, when the evaporator cushion block is used for the evaporator 210 with 3 bent rows 212, three cushion block bodies 100 are spliced and arranged at each position where the evaporator cushion block is required; as Figure 9 shown, when the evaporator cushion block is used for the evaporator 210 with 2.5 bent rows 212, two or three cushion block bodies 100 are correspondingly spliced and arranged according to the number of bent rows 212 at each position where the evaporator cushion block is required; as Figure 10 shown, when the evaporator cushion block is used for the evaporator 210 with 1.5 bent rows 212, one cushion block body 100 is correspondingly arranged or two cushion block bodies 100 are spliced and arranged according to the number of bent rows 212 at each position where the evaporator cushion block is required.
[0057] In the specific content of the above specific embodiments, the technical features can be combined arbitrarily without contradiction. For the sake of brevity of description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should be considered as the scope recorded in this specification.
[0058] The specific content of the above specific embodiments only expresses several embodiments of the present invention, and its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
