The utility model provides an evaporator external member for the refrigerator.
Fig. 1 and 2 show one embodiment of an evaporator kit of the present invention. Fig. 1 is a schematic structural diagram of an embodiment of an evaporator kit according to the present invention; fig. 2 is a side view of the evaporator assembly of fig. 1.
Referring to fig. 1, the evaporator kit includes an evaporator 100 and a defrosting heating pipe 200 installed below the evaporator 100. The defrosting heating pipe 200 includes a heating section 210 disposed in a spiral shape, and an axis of the heating section 210 is parallel to a length direction of a bottom wall of the evaporator 100. When the heating section 210 operates, heat is generated and radiated to the surrounding air, and the heated air heated by the heat radiation naturally rises, so that the evaporator 100 above the heating section 210 is heated, and a defrosting effect is achieved.
In the present embodiment, the evaporator 100 is a flat plate extending in the left-right direction, and the heat generating section 210 extends spirally in the left-right direction. Of course, in other embodiments, when the evaporator 100 extends in an L-shape, the heat generating section 210 extends spirally along the L-shaped path; when the evaporator 100 extends in a C-shape, the heat generating section 210 also extends spirally along the C-shaped path. The pitches of the heat generating sections 210 can be set differently to achieve different defrosting effects for matching with different evaporators 100. Wherein the heat generating section 210 is shaped like a spring, and thus the heat generating section 210 is described in terms of a spring; the pitch is the distance between the corresponding points of two adjacent circles in the heat generating section 210 on the axis. The free length hereinafter is a straight distance between both ends of the heat generating section 210.
In order to solve the technical problem mentioned in the background art, in the evaporator set provided in this embodiment, the heating section 210 of the defrosting heating pipe 200 extends spirally, so that the heat exchange area between the heating section 210 and the air can be increased by reducing the pitch under the condition that the distance between the two ends is not changed. And the pitch is increased, the space occupied by the defrosting heating pipe 200 is basically unchanged, and therefore, the space utilization rate of the defrosting heating pipe 200 provided by the embodiment is higher.
Preferably, the evaporator 100 includes two mounting plates 110, an evaporation tube 120, and a plurality of fins 130; the two mounting plates 110 extend in the up-down direction and are spaced apart in the left-right direction. The evaporation tube 120 comprises a plurality of parallel tube segments 121 which are positioned between the two mounting plates 110 and are arranged at intervals in the vertical direction, and a U-shaped tube segment 122 which is positioned outside the two mounting plates 110 and two ends of which are respectively connected with the two adjacent parallel tube segments 121; the plurality of fins 130 are sleeved on the plurality of parallel tube segments 121.
The heating section 210 is installed between the two installation plates 110, and the defrosting heating pipe 200 further includes two connection sections 220, wherein the two connection sections 220 are respectively connected to two ends of the heating section 210 and extend along the axis of the heating section 210 in the back direction. The two connection sections 220 are connected to the two mounting plates 110, respectively. The connecting section 220 may be welded, threaded, or snapped onto the two mounting plates 110. Preferably, the front or rear ends of the two mounting plates 110 are notched, and the connecting section 220 is snapped into the notches. For the purpose of facilitating the snap-in, the connection section 220 extends perpendicular to the plate surface of the mounting plate 110. In this embodiment, the defrosting heating pipe 200 and the evaporating pipe 120 are both connected to the mounting plate 110, so that the defrosting heating pipe 200 and the evaporating pipe 120 have a common positioning base, and have an effect of easier mutual positioning.
The heating of the defrosting heating pipe 200 is mainly concentrated on the heating section 210, and the connecting section 220 may be heated or not heated.
Preferably, the fins 130 extend in the up-down direction, and an ascending air duct is formed between two adjacent fins 130. The ascending air duct is used for enabling ascending air flow to be in full contact with the fins 130 in the ascending process, and the effect of higher heat utilization rate is achieved. Since the heat generated by the heating section 210 can achieve a better defrosting effect only when the hot air enters the ascending air channel between two adjacent fins, the heating section 210 is preferably disposed right below the plurality of fins 130.
Referring to fig. 2 in combination, preferably, the evaporator 100 has a thickness L1 in the front-rear direction; the axis of the heat generation section 210 is disposed corresponding to the middle position in the thickness direction of the evaporator, and the outer diameter of the heat generation section is L2. Wherein, L1-L2 is more than or equal to 20mm, namely the outer contour of the heating section and the front and the back of the evaporator 100 are arranged at intervals of more than 10 mm. Since the heat generating section 210 generates high heat during operation, in the present embodiment, the heat generating section 210 is retracted between two surfaces of the evaporator 100, and the distance from other surrounding parts is increased, so as to prevent the heat generated by the heat generating section 210 from damaging the surrounding parts. For example, if a painted housing is heated severely, the paint surface is easily peeled off and rusted.
Preferably, the two mounting plates 110 are spaced apart at a distance L3 in the left-right direction, and the free length of the heat generating section 210 is L4. Wherein L3-L4 is more than or equal to 20mm, namely, the two ends of the heating section can be respectively arranged at intervals of more than 10mm with the two mounting plates 110. Since the heating section 210 is spiral, it is difficult to install it on the mounting plate 110, and the connection section 220 is conveniently connected to the mounting plate 110 by reserving a 10mm interval.
Preferably, the pitches of the whole sections of the heating section 210 are uniformly arranged, so that a relatively uniform heat dissipation effect can be generated, and the effect of uniform hot air rising on the overall defrosting is better. Of course, in other embodiments: the left part, the middle part and the right part of the heating section 210 are arranged in different pitches to generate different defrosting effects, so that important defrosting can be performed on areas with severe defrosting, for example, in the axis direction, the middle part of the heating section is arranged towards the two ends of the heating section in a lengthening mode, namely the middle part is dense, and the two ends of the heating section are sparse.
Preferably, the defrosting heating pipe 200 is an electric heating pipe, the defrosting heating pipe 200 is provided with an energization terminal (not shown) receiving electric power, and the defrosting heating pipe 200 generates heat when energized. The power-on generates heat, and the heating device has the advantages of simple and mature structure, and easy quick heating starting and quick heating stopping effects. Of course, in other embodiments: the defrosting heating pipe 200 is a hollow pipe for circulating high-temperature liquid, and heat is dissipated when the high-temperature liquid flows in the defrosting heating pipe 200. The heat of the hot water can come from the compressor or other heat generating components.
The utility model also provides a refrigerator, this refrigerator includes controller, fan and evaporimeter external member, and the concrete structure of this evaporimeter external member refers to above-mentioned embodiment, because this refrigerator has adopted the whole technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer given here. When the refrigerator is used for refrigerating, the controller controls the fan to rotate when the refrigerator normally works, so that air blowing to the evaporator kit is generated, and the defrosting heating pipe 200 is controlled to stop working; when the refrigerator is defrosted, the controller controls the fan to stop rotating and controls the defrosting heating pipe 200 to heat.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
