The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

An evaporator assembly 100 according to an embodiment of the present invention is described below with reference to the drawings.

Referring to fig. 1 and 2, an evaporator assembly 100 according to an embodiment of the present invention includes an evaporator 1 and a heating member 2. The evaporator 1 has a channel through which the air flow passes, the air flow passing through the channel flowing in a first direction (refer to direction D1 in the figure), and the evaporator 1 can exchange heat with the air flow in the channel. The heating member 2 is provided on the evaporator 1, so that the heating member 2 is provided, and at least a part of the heating member 2 is opposed to the evaporator 1 in a second direction (for example, the second direction is a thickness direction of the evaporator 1, refer to a direction D2 in the drawing) perpendicular to the first direction. For example, a part of the heating member 2 is opposed to the evaporator 1 in the second direction; alternatively, the heating member 2 is entirely opposed to the evaporator 1 in the second direction.

Since at least a part of the heating member 2 is opposite to the evaporator 1 in the second direction, the heat released from the heating member 2 is more easily absorbed by the evaporator 1, that is, the heat conductivity of the heating member 2 to the evaporator 1 can be improved, thereby improving the defrosting efficiency. For example, when the heating member 2 is plate-shaped, a part of the heating member 2 is opposed to the evaporator 1 in the second direction, and both the heating member 2 and the evaporator 1 extend in the first direction, the heat released from the heating member 2 is transferred to the evaporator 1 in the form of heat radiation substantially in the second direction, and the defrosting efficiency is high. Simultaneously, owing to improved heating member 2's defrosting efficiency, can reduce the power of heating member 2 and in order to reduce the energy consumption of heating member 2, the temperature on heating member 2 surface is lower when heating member 2 during operation, safer compliance. Particularly, when the evaporator assembly 100 is applied to a refrigerator, the heating element 2 has a lower temperature during operation, which is beneficial to reducing the temperature rise during defrosting of the refrigerator, and is beneficial to keeping food fresh.

On the other hand, the heating member 2 during operation makes the air heating up around the heating member 2, because the air current flows along the first direction, the heating member 2 can be followed the first direction and extended, make the effect of blockking of heating member 2 to the air current less, the air current flows more smoothly, be favorable to the air current around the evaporimeter 1 to form the convection current, make evaporimeter 1 be in under comparatively even temperature field, the air of high temperature rises and can melt the frost on evaporimeter 1 upper portion, thereby it is even to make the whole frost of evaporimeter 1, avoided heating member 2 during operation to produce more ineffective heat.

According to the utility model discloses an evaporator assembly 100, through setting up heating member 2, heating member 2 is established on evaporimeter 1, heating member 2 can defrost evaporimeter 1, because at least some and evaporimeter 1 of heating member 2 are relative on the second direction, second direction perpendicular to first direction, make heating member 2 conduct the heat to evaporimeter 1 more easily on, it is efficient to change the frost, and can reduce the power of heating member 2, thereby reduce the surface temperature of heating member 2, safer compliance, heating member 2 is less to the effect of blockking of air current simultaneously, the air current circulation in the passageway is smooth and easy, be favorable to making evaporimeter 1 be in under comparatively even temperature field, make evaporimeter 1 whole frost even.

Referring to fig. 4, according to some embodiments of the present invention, the heating member 2 is a heating plate. This kind of design makes heating member 2 can generate heat in the whole face, and it is even just to generate heat efficient, can improve heating member 2's defrosting efficiency. Meanwhile, the heating plate can be made thinner, so that the heat storage of the heating plate is less, the surface temperature is rapidly increased when the heating plate works, and the surface temperature is rapidly decreased when the heating plate does not work, so that the heat utilization rate is improved. For example, the heating plate is formed by compounding two layers of heating films, the inner layer of each layer of heating film is an electrothermal film which can be electrically heated, resin layers are coated on two sides of the electrothermal film, and the resin layers can be insulated and damp-proof. The width direction of the heating plate 2 (the width direction of the heating plate 2 is perpendicular to the first direction, and perpendicular to the second direction, refer to the D3 direction in the figure) may be substantially the same as the width direction of the evaporator 1 (the width direction of the evaporator 1 is perpendicular to the first direction, and perpendicular to the second direction, refer to the D3 direction in the figure), and the heating plate 2 may extend out to both sides of the evaporator 1 along the width direction, so that the heating plate 2 may effectively defrost both sides of the evaporator 1 in the width direction, and the evaporator 1 is defrosted uniformly.

Referring to fig. 1 and 2, the heating member 2 may alternatively be angled in the range of 0-30 deg. from the first direction. Because the air current flows along the first direction, inject the contained angle at less angular range through the plane with heating member 2 place and first direction, can reduce the effect of blockking of heating member 2 to the air current for the air current flows more smoothly, is favorable to the air current around the evaporimeter 1 to form the convection current, makes evaporimeter 1 be in under comparatively even temperature field, thereby makes the whole frost of evaporimeter 1 even. On the other hand, when the evaporator 1 is extended substantially in the first direction, the heating member 2 may be disposed substantially in parallel with the evaporator 1, and the heating member 2 may be located closer to the evaporator 1, so that heat released from the heating member 2 is easily transferred to the evaporator 1, thereby improving defrosting efficiency of the heating member 2.

Referring to fig. 1 and 2, further, the heating member 2 is parallel to the first direction. The design further reduces the blocking effect of the heating element 2 on the air flow, so that the air flow flows more smoothly, the convection of the air flow around the evaporator 1 is facilitated, the evaporator 1 is in a more uniform temperature field, and the defrosting of the evaporator 1 is uniform as a whole. On the other hand, when the evaporator 1 extends substantially in the first direction, the heating member 2 may be disposed substantially in parallel with the evaporator 1, and the heating member 2 may be closer to the evaporator 1, so that the heat released from the heating member 2 is more easily transferred to the evaporator 1, thereby further improving the defrosting efficiency of the heating member 2.

Referring to fig. 1 and 2, according to some embodiments of the present invention, the heating member 2 is adjacent to an upstream end of the flow direction of the air flow of the evaporator 1. Because the airflow in the channel flows from the upstream end to the downstream end, the design enables the heat released by the heating element 2 to be transferred from the upstream end to the downstream end along with the airflow in the flowing direction of the airflow, so that the heat passes through the whole evaporator 1, the heat utilization rate is improved, and the evaporator 1 is defrosted uniformly. For example, when the evaporator assembly 100 is applied to a refrigerator, the flow direction of the air flow in the passage may be from the lower portion of the evaporator 1 to the upper portion of the evaporator 1, since the heating member 2 heats the surrounding air when operating, the heating member 2 heats the air at the upstream end of the flow direction of the air flow, and the air of high temperature flows to the upper portion of the evaporator 1. The high-temperature air flows through the evaporator 1 from bottom to top in the flowing process, so that the evaporator 1 can be defrosted integrally.

Referring to fig. 1-3, according to some embodiments of the present invention, at least a portion of the heating element 2 extends into the evaporator 1. For example, a part of the heating member 2 protrudes into the evaporator 1, or the heating member 2 protrudes entirely into the evaporator 1. The design enables the heat released by the heating element 2 to be more effectively transferred into the evaporator 1, improves the defrosting efficiency and enables the evaporator 1 to defrost uniformly. On the other hand, when the evaporator assembly 100 is applied to a refrigerator, at least a portion of the heating member 2 protrudes into the evaporator 1, so that the evaporator 1 has a certain heat insulation effect, and other structures of the refrigerator are prevented from being damaged when the temperature of the heating member 2 is too high.

Referring to fig. 2, according to some alternative embodiments of the present invention, the evaporator 1 includes two opposite and connected sub-evaporators 1a, and at least a portion of the heating element 2 is located between the two sub-evaporators 1a, so as to facilitate the extension of at least a portion of the heating element 2 into the evaporator 1, thereby facilitating the installation of the heating element 2. For example, a part of the heating member 2 is located between the two sub-evaporators 1 a; or the heating member 2 is integrally located between the two sub-evaporators 1 a. This design allows the heat released from the heating member 2 to be more efficiently transferred to the two sub-evaporators 1a, so that the sub-evaporators 1a are defrosted uniformly. On the other hand, when the evaporator assembly 100 is applied to a refrigerator, two sub-evaporators 1a are located at both sides of the heating member 2, and the sub-evaporators 1a have a certain heat insulating function to prevent damage to other structures of the refrigerator when the heating member 2 is excessively hot.

In some optional embodiments of the present invention, the evaporator 1 includes two opposite and connected sub-evaporators 1a, the two sub-evaporators 1a are detachably connected, and at least a portion of the heating member 2 is located between the two sub-evaporators 1a, so that the evaporator 1 and the heating member 2 are convenient to assemble.

Referring to fig. 4, according to some alternative embodiments of the present invention, the first direction is an up-down direction, the heating member 2 includes a first heating part 21 and a second heating part 22 connected up and down, the first heating part 21 is located in the evaporator 1, and the second heating part 22 is located below the evaporator 1. The first heating part 21 may conduct heat to the inside of the evaporator 1 by heat radiation, the first heating part 21 and the second heating part 22 may heat surrounding air, and the air of high temperature rises and covers the entire evaporator 1, so that the evaporator 1 defrosts uniformly. On the other hand, when the evaporator assembly 1 is applied to a refrigerator, the evaporator assembly 100 may be disposed in an evaporator chamber of the refrigerator, and condensed water may be condensed on a bottom wall and a side wall adjacent to the bottom wall of the evaporator chamber, and the performance of the refrigerator may be affected by freezing of the condensed water when the refrigerator is operated, so that the heating member 2 may melt frost on the bottom wall and the side wall of the evaporator chamber when the heating member 2 is operated by disposing the second heating portion 22 below the evaporator 1, thereby improving the performance of the refrigerator.

Referring to fig. 1, 2 and 4, further, the heating member 2 is a heating plate, and this design enables the heating member 2 to generate heat on the whole surface, so that the heating efficiency is high and uniform, and the defrosting efficiency of the heating member 2 can be improved. Meanwhile, the heating plate can be made thinner, so that the heat storage of the heating plate is less, the surface temperature is rapidly increased when the heating plate works, and the surface temperature is rapidly decreased when the heating plate does not work, so that the heat utilization rate is improved. The second heating part 22 is formed with a circulation hole 221 through which the air flow passes, and by providing the circulation hole 221, the second heating part 22 can be prevented from blocking the air flow, which is beneficial to the circulation air flowing to both sides of the evaporator 1, so that the circulation air is uniformly distributed.

Referring to fig. 1 to 3, according to some alternative embodiments of the present invention, the upper edge of the first heating part 21 is located at the middle in the up-down direction of the evaporator 1. For example, when the evaporator assembly 100 is applied to a refrigerator, since the condensed water attached to the evaporator 1 flows downward by gravity, when frost is formed on the evaporator 1, more frost is formed on the lower portion of the evaporator 1, and less frost is formed on the upper portion of the evaporator 1. When the first heating part 21 operates, the first heating part 21 may conduct heat to the lower portion of the evaporator 1 by heat radiation, and at the same time, the first heating part 21 may heat the ambient air, and the air of high temperature rises and reaches the upper portion of the evaporator 1. Since the heat conducted by the heat radiation is more than the heat conducted by the high temperature air and the heat conduction speed of the heat radiation is fast, the upper part of the evaporator 1 absorbs less heat, the lower part of the evaporator 1 absorbs more heat, and the lower part of the evaporator 1 absorbs heat faster. The design ensures that the heat released by the heating element 2 during working is more reasonably distributed, the upper part of the evaporator 1 with less frost formation and the lower part of the evaporator 1 with more frost formation can almost simultaneously complete the defrosting, and the ineffective heat generated by the heating element 2 during working is reduced.

Referring to fig. 1 to 3, according to some embodiments of the present invention, the evaporator 1 includes an evaporator body 11 and side plates 12 disposed at opposite sides of the evaporator body 11, the side plates 12 are formed with mounting lugs 121, the mounting lugs 121 are connected to the heating members 2, the mounting lugs 121 may be formed with mounting holes, and a fastener may pass through the mounting holes and the heating members 2 to connect the evaporator 1 and the heating members 2, so that the heating members 2 are conveniently fixed.
