[0032] Embodiment 1

[0033] The present embodiment provides an electric heating structure, such as Figures 1-6As shown, the electric heating structure is applied to the evaporator 1 having an open space 12 formed by multiple bends 11, and the electric heating structure comprises a heating body 2 and a heat dissipating unit 3, the heating body 2 matches the shape of the evaporator 1 and is located in the open space 12, and the heat dissipating unit 3 is formed on the heating body 2 so that the heat generated by the heating body 2 can be uniformly transmitted to the evaporator 1.

[0034] Specifically, the evaporator 1 is an important component in the refrigeration four-piece, and the low-temperature condensed "liquid" body exchanges heat with the air outside through the evaporator, and the "gas" is heated to achieve the effect of refrigeration. The evaporator 1 is mostly a bent structure. In this embodiment, the evaporator 1 has multiple bends 11, for example, assuming that the evaporator 1 includes a first surface, a second surface, and a third surface, the first surface and the second surface are connected and have a first included angle therebetween, which is a first bend, and the second surface and the third surface are connected and have a second included angle therebetween, which is a second bend, wherein the first included angle and the second included angle are both acute angles, so that an open space 12 is formed at the positions towards the first included angle and the second included angle. In order to improve the effect of the air conditioner, the heating body 2 is arranged in the open space 12, and the heating body 2 works together with the compressor to improve the refrigeration and heating effect of the air conditioner.

[0035] The traditional electric heating structure is long strip-shaped and located inside the evaporator. During the operation of the air conditioner, the air flow around the electric heating structure rises in temperature quickly, that is, the temperature inside the evaporator rises quickly, while the air around the two ends of the evaporator rises in temperature slowly because it is far away from the electric heating structure, thereby causing a temperature difference. The temperature difference can cause the fins of the evaporator to deform to a certain extent, affecting the heat exchange efficiency of the evaporator, and thus reducing the quality of the entire air conditioner. In this embodiment, the heating body 2 matches the shape of the evaporator 1 and is located in the open space 12, that is, the heating body 2 also includes three surfaces, and in order to make the technology more detailed and clear, it is assumed that the heating body 2 includes a fourth surface, a fifth surface, and a sixth surface, the fourth surface corresponds to the first surface, the fifth surface corresponds to the second surface, and the sixth surface corresponds to the third surface, the fourth surface and the fifth surface have a third included angle, the third included angle is the same as the first included angle, and the fifth surface and the sixth surface have a fourth included angle, the fourth included angle is the same as the second included angle. Of course, the evaporator 1 can also include four surfaces, five surfaces, etc., which are not specifically limited here.

[0036] When the heating body 2 matches the shape of the evaporator 1 and is located in the open space 12, compared with the traditional long strip-shaped heating body 2, the heating body 2 of this embodiment obviously covers a larger area of the evaporator, to a certain extent, alleviating the problem of fin deformation of the evaporator 1 due to a large temperature difference.

[0037] And, on the basis of the above, the heat dissipation unit 3 is further included in the embodiment, which is arranged on the heating body 2 and can make the heat generated by the heating body 2 evenly transmitted to the evaporator 1. This further ensures the uniformity of the temperature of the evaporator 1.

[0038] Therefore, the electric heating structure provided by the embodiment can greatly improve the heating effect and prevent the evaporator 1 from frosting, because the heating body 2 has a wide distribution range compared with the traditional heating body and has the heat dissipation unit 3. Thus, under extremely low temperature conditions, only the compressor heating may not meet the user's heating demand, and the electric heating structure can provide additional heat to ensure that the indoor temperature reaches the user's set value. The air conditioner can quickly reach the best state and quickly start.

[0039] In specific embodiments, the heat dissipation unit 3 includes a through hole arranged on the heating body 2.

[0040] Specifically, the through hole is arranged on the heating body 2, i.e. the heating body 2 is a mesh structure, which can make the heat evenly transmitted to the air flow around the evaporator 1, so as to improve the heat exchange efficiency. On the other hand, the arrangement of the through hole makes the air around the evaporator 1 flow normally without wind blocking, thus avoiding the noise problem.

[0041] In specific embodiments, the through hole is a square and has a plurality of square through holes arranged in rows and columns on the heating body 2.

[0042] Specifically, each face of the heating body 2 has square through holes arranged in rows and columns. The square through hole has a large heat dissipation area and good ventilation effect, and is simple to process. Of course, the through hole can also be rectangular, triangular or polygonal. In addition, the square through hole penetrates the length and width directions of each face, i.e. the through hole basically covers the entire heating body 2, so that the heat generated by the heating body 2 can be evenly transmitted to the evaporator 1, thereby further ensuring the uniformity of the temperature of the evaporator 1.

[0043] In specific embodiments, the bending part of the heating body 2 is provided with a copper pipe 21. The heating body 2 has multiple surfaces which are integrally formed. The copper pipe 21 provided at the bending part can increase the stability of the bending part, avoiding the heating body 2 from being easily broken or damaged at the bending part. Moreover, copper has good heat conduction performance, which can transfer heat, making the heat on the heating body 2 more uniform, thereby ensuring that the periphery of the evaporator 1 has uniform temperature, avoiding the problem of fin deformation caused by large temperature difference.

[0044] In specific embodiments, the electric heating structure further comprises a condensed water collecting unit 4, one end of the condensed water collecting unit 4 is located on the evaporator 1 for collecting the condensed water generated by the evaporator 1, and the other end of the condensed water collecting unit 4 is located at the end of the heating body 2 for draining the condensed water out of the heating body 2.

[0045] In the cooling mode of the air conditioner, air is simultaneously sent from the three surfaces of the evaporator 1. Since the hot air inside the evaporator 1 meets the cold air, condensation is easily formed inside the evaporator 1, which can affect the working performance of the evaporator 1 and the heating body 2. Based on this, the present embodiment adds a condensed water collecting unit 4, one end of the condensed water collecting unit 4 is located on the evaporator 1, and the other end of the condensed water collecting unit 4 is located at the end of the heating body 2. In this way, by using the above structure, when the hot air inside the evaporator 1 meets the cold air, condensed water is generated on the surface of the evaporator 1, which is collected by the condensed water collecting unit 4 and transported out of the heating body 2, avoiding the influence of the condensed water on the evaporator 1 and the heating body 2.

[0046] In specific embodiments, the condensed water collecting unit 4 comprises a water absorbing strip 41, a flow guide groove 42 and a water receiving groove 43, the water absorbing strip 41 and the flow guide groove 42 are both arranged on the side of the heating body 2 facing the evaporator 1, and the water absorbing strip 41 is connected with the flow guide groove 42, and the water receiving groove 43 is located at the bottom of the two sides of the heating body 2.

[0047] More specifically, the water absorbing strip 41 is made of silica gel material and is adhered to the heating body 2 by gluing. Silica gel material has good water absorption. The inside of silica gel is a nano-level microporous structure, and there are a large number of hydroxyl groups on its surface. Through the mutual attraction between molecules, the hydroxyl groups are affinity with the water molecules in the air, thereby realizing water absorption. Moreover, silica gel material can withstand high temperature above 200 degrees Celsius and prevent mold. The water absorbing strip 41 is arranged on the side of the heating body 2 facing the evaporator 1, so that when the hot air inside the evaporator 1 meets the cold air and forms condensed water on the evaporator 1, the wind will blow the condensed water on the evaporator 1 to the heating body 2 when the air enters, and then the water absorbing strip 41 arranged on the heating body 2 absorbs it.

[0048] The guide groove 42 is arranged on the side of the heating body 2 facing the evaporator 1, and intersects with the water absorbing strip 41, so that when the water absorbing strip 41 is full of water, the water flows into the guide groove 42, and then flows into the water receiving groove 43.

[0049] In specific embodiments, the water absorbing strip 41 is made of silica gel, and a plurality of water absorbing strips 41 are arranged on the heating body 2 in the vertical direction; and / or a plurality of guide grooves 42 are arranged on the heating body 2 in the horizontal direction.

[0050] More specifically, the plurality of water absorbing strips 41 are arranged vertically between two adjacent columns of through holes, and the plurality of guide grooves 42 are arranged horizontally between two adjacent rows of through holes, so that the water absorbing strips 41 and the guide grooves 42 are arranged in a horizontal and vertical intersection manner, so that the condensed water at any position can be collected.

[0051] That is, after the condensate water collecting unit 4 provided in the embodiment is used, the wind blows the water on the evaporator 1 to the heating body 2 when the air enters, at which time the water absorbing strip 41 absorbs the water on the evaporator 1, and transfers the water to the water receiving grooves 43 at both ends through the horizontally arranged guide grooves 42.

[0052] The electric heating structure provided in the embodiment improves the heating body, so that the heat is uniformly transmitted to the airflow around the evaporator 1, avoids the temperature difference of the airflow around the end of the evaporator 1, improves the heat exchange efficiency of the indoor unit, and the heating body 2 is a hollow structure, which does not block the wind, thereby avoiding the noise problem.

[0053] Embodiment 2

[0054] The embodiment provides an air conditioner, which comprises the electric heating structure of embodiment 1.

[0055] In specific embodiments, when the electric heating structure comprises the condensate water collecting unit 4, and the condensate water collecting unit 4 comprises the water receiving groove 43, the air conditioner further comprises a humidity adjusting unit 5, the humidity adjusting unit 5 comprises a controller 51, a humidity detecting member 52, and a pump body 53, the humidity detecting member 52 is arranged indoors, the pump body 53 is arranged at the bottom of the water receiving groove 43, and the controller 51 is arranged in the air conditioner; the humidity detecting member 52 can transmit the detected indoor humidity to the controller 51, the controller 51 controls the pump body 53 according to the indoor humidity, so that the pump body 53 does not work or works to transport the water in the water receiving groove 43 to the heating body 2.

[0056] More specifically, the humidity detecting member 52 in the embodiment is a humidity sensor, which is arranged indoors. The humidity sensor works in the following way: a humidity-sensitive element (such as a resistance or a capacitor) is sensitive to the ambient humidity, and converts the humidity change into a change in electrical signal, thereby achieving the measurement of humidity.

[0057] Since the air conditioner is continuously running in the cooling mode to send air, the indoor environment is relatively dry. Therefore, the humidity sensor is arranged on the outer surface of the air conditioner. When the humidity is lower than a threshold value, the water in the water collecting groove 43 is transmitted to the heating body 2 by the pump body 53 under the action of the controller 51, and is changed into water vapor after being heated, and is finally blown to the indoor environment by the air deflector, thereby supplementing the indoor humidity and achieving the effect of constant humidity cooling. In addition, there are many ways for the pump body 53 to transmit water to the heating body 2, such as through a water pipe, and the end of the water pipe is provided with a spray head, which faces the heating body 2.

[0058] In a specific embodiment, the condensate water collecting unit 4 further comprises a water level sensor 44 and a drain valve 45 connected with the controller 51. The water level sensor 44 is arranged in the water collecting groove 43, and the drain valve 45 is arranged at the bottom of the water collecting groove 43.

[0059] In the embodiment, if the indoor humidity detected by the humidity sensor meets the condition, but the water level in the water collecting groove 43 detected by the water level sensor 44 is higher than a set threshold value, the water in the water collecting groove 43 will flow to the outdoor environment through the drain valve 45 and the drain pipe under the action of the controller 51.

[0060] The electric heating structure of the evaporator of the conventional air conditioner indoor unit is arranged at the glue port position on the inner side of the evaporator, so that the airflow at the inner side of the evaporator is heated more than the airflow at the left and right ends. Compared with the conventional electric heating structure, the electric heating structure of the embodiment can completely cover the inner side of the evaporator, so that the airflow around the evaporator can be uniformly heated, thereby improving the heat exchange efficiency of the evaporator and the temperature adjustment effect. In addition, the arrangement of the through hole can effectively solve the noise problem caused by the vortex.

[0061] In summary, those skilled in the art can easily understand that the above advantageous technical features can be freely combined and superimposed without conflict.

[0062] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification made according to the technical essence of the present application are still within the scope of the technical solution of the present application.
