Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air guide structure and an air conditioner. Background Art

[0002] With the improvement of people's living standards, air conditioners have become a must-have appliance in every household. Figure 1 The figure is a schematic diagram of the existing air guide structure and evaporator of the air conditioner. The direction indicated by the arrow in the figure is the approximate direction of the external wind entering the air guide structure and blowing toward the evaporator. Due to the limitation of the air guide structure, the flow direction of part of the wind is parallel or nearly parallel to the extension direction of the evaporator. It is difficult for most or all of this part of the wind to blow toward the evaporator, resulting in low utilization of the evaporator, and thus the cooling effect of the air conditioner cannot reach the best.

[0003] It can be seen that users are in urgent need of a new air guide structure to improve the utilization rate of the evaporator. Summary of the invention

[0004] The problem solved by the invention is that the utilization rate of the evaporator of the existing air conditioner is low.

[0005] In order to solve the above problems, the present invention provides an air guide structure, including a middle frame body and an air guide plate, one side of the air guide plate is fixed to the middle frame body, and the other side extends toward the interior of the middle frame body; in the assembled state, the extension direction of the air guide plate passes through the evaporator provided in the middle frame body, and is suitable for guiding the incoming air passing through the air guide plate to blow toward the evaporator.

[0006] In this way, the air guide piece is located on the flow path of the wind, and can guide the wind entering the middle frame body to blow toward the evaporator, thereby improving the utilization rate of the evaporator and further improving the cooling effect of the air conditioner.

[0007] Optionally, the air guide plate is arranged on the inner side of the middle frame body; in the assembled state, the angle formed between the plane where the extension direction of the air guide plate is located and the air inlet surface of the evaporator facing the air guide plate is 85°-90°.

[0008] In this way, the air guide piece is nearly perpendicular to the side of the evaporator facing it, and can guide the wind to blow vertically toward the evaporator, thereby maximizing the utilization rate of the evaporator and ensuring the best cooling effect of the air conditioner.

[0009] Optionally, the number of the air guide blades is 2-5.

[0010] In this way, the number of the air guide plates is moderate, and the utilization rate of the evaporator is improved while ensuring that the obstruction to the flow of wind is small.

[0011] Optionally, an air inlet end and an air outlet frame are provided on the middle frame body. In an assembled state, along the direction from the air inlet end to the air outlet frame, the distance between the air guide plate and the evaporator gradually decreases.

[0012] In this way, along the direction of wind flow, the distance between the air guide plate and the evaporator gradually decreases, which can ensure that the wind is less obstructed when the wind volume is large, and ensure that sufficient wind is blown to the part of the evaporator close to the air outlet frame; when the wind volume is small, it can ensure that most of the small amount of wind is guided to the evaporator, thereby improving the utilization rate of the evaporator.

[0013] Optionally, the air guide blades are parallel to each other.

[0014] In this way, the wind can be guided to blow evenly toward the evaporator, further improving the utilization rate of the evaporator.

[0015] Optionally, along the direction from the air inlet end to the air outlet frame, the distance between adjacent air guide plates gradually decreases.

[0016] In this way, as the air volume decreases along the flow direction of the wind, the distance between the air guide vanes gradually decreases, and the air guide vanes are distributed more and more densely, which can enhance the wind guiding effect when the air volume is small and further improve the utilization rate of the evaporator.

[0017] Optionally, the length of the air guide plate is not less than the length of the evaporator.

[0018] In this way, the air guide plate can guide the wind to blow to all parts of the evaporator in the length direction, further improving the utilization rate of the evaporator.

[0019] Optionally, the air guide piece is detachably connected to the middle frame body.

[0020] In this way, it is convenient to disassemble the air guide plates, change the number of the air guide plates, and further change the wind guidance according to the air volume, so as to ensure a high utilization rate of the evaporator.

[0021] Optionally, a slot is provided on the middle frame body, and the air guide plate is suitable for being inserted into the slot.

[0022] In this way, the connection structure between the middle frame body and the air guide blades is simple and the cost is low; it is also convenient to disassemble the air guide blades and to change the number of the air guide blades.

[0023] Another object of the present invention is to provide an air conditioner to solve the problem of low utilization rate of the evaporator of the existing air conditioner.

[0024] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0025] An air conditioner comprises any one of the above-mentioned air guide structures.

[0026] The advantages of the air conditioner and the above-mentioned air guide structure over the prior art are the same, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] like Figure 2 As shown, it is a schematic diagram of the cross-section of the air guide structure and the evaporator 10 of the air conditioner in this embodiment; wherein, the air guide structure includes a middle frame body 20 and an air guide plate 30, one side of the air guide plate 30 is fixed to the middle frame body 20, and the other side extends toward the inside of the middle frame body 20; in the assembled state, the extension direction of the air guide plate 30 passes through the evaporator 10 arranged in the middle frame body 20, and is suitable for guiding the incoming air passing through the air guide plate 30 to blow toward the evaporator 10.

[0035] It should be noted that the inner and outer sides in this embodiment are based on the center of the middle frame body 20, the side away from the center of the middle frame body 20 is the outer side, and the side close to the center of the middle frame body 20 is the inner side. Figure 3 As shown, the front side of the middle frame body 20 (i.e. Figure 2In this embodiment, the air guide 30 is a rectangular strip structure, one side of which is fixed to the inner side of the hollow grille 201 on the middle frame body 20 in the width direction, and the other side extends to the inside of the middle frame body 20. The extension refers to the extension of the air guide 30 in the width direction, and the width direction is the direction from the fixed side of the air guide 30 to the free side. Figure 2 As shown, the direction indicated by the arrow is the air inlet direction, which can be generally regarded as from left to right. The overall direction in which the wind enters the middle frame body 20 and blows toward the evaporator 10 can also be regarded as from left to right. Specifically, as Figure 4 As shown, one side of the middle frame body 20 (i.e. Figure 2 The left side of the middle frame 20 is provided with an air inlet grille 204, and the outside air enters the interior of the middle frame body 20 through the air inlet grille 204. It can be understood that the installation position of the air guide plate 30 in this embodiment is determined by the assembly relationship between the middle frame body 20 and the evaporator 10, that is, the air guide plate 30 must be close to the air inlet side of the evaporator 10 and be on the air inlet path, which is shown in Figure 2 The middle refers to the lower left, upper left and upper part of the middle frame body 20 .

[0036] In this way, the air guide plate 30 is located on the wind flow path. When the incoming air passes through the air guide plate 30, the air guide plate 30 can guide the wind entering the middle frame body 20 to blow toward the evaporator 10, thereby improving the utilization rate of the evaporator 10 and further improving the cooling effect of the air conditioner.

[0037] Generally speaking, if Figure 2 As shown, the evaporator 10 includes three sections of fins: a first fin 101, a second fin 102 and a third fin 103. Since the incoming air basically blows directly to the third fin 103, the utilization rate of the third fin 103 is high, so there is no need to Figure 2 The air guide 30 is installed at the lower left of the third fin 103 to guide the incoming air to blow toward the third fin 103. Figure 2 The upper left or upper part of the fin 100 guides the incoming air to blow toward the first fin 101 and the second fin 102. Figure 2 In the figure, the air guide piece 30 is installed at the upper left part inside the middle frame body 20 to guide the incoming air to blow towards the second fin 102 .

[0038] In actual situations, for the air conditioner in this embodiment, it is verified that when the thickness of the air guide plate 30 is 1 cm and the width is 16 or 17 cm, the air guide plate 30 has a better wind guiding effect. The width is the distance between the fixed side of the air guide plate 30 and its free side.

[0039] Optionally, the air guide plate 30 is arranged on the inner side of the middle frame body 20; in the assembled state, the angle formed between the plane where the extension direction of the air guide plate 30 is located and the air inlet surface of the evaporator 10 facing the air guide plate 30 is 85°-90°.

[0040] The extension direction of the air guide plate 30 refers to the direction from the fixed side of the air guide plate 30 to the free side thereof, which is shown in Figure 2 The fixed end of the air guide fin 30 points to the direction of its free end. The air inlet surface of the evaporator 10 is the plane where the outer side surface of each fin section is located, which is shown in Figure 2 The plane where the outer side of the first fin 101 or the second fin 102 is located. The evaporator 10 directly facing the air guide fin 30 refers to: a section of the fin of the evaporator 10 to which the extension direction of the air guide fin 30 points and to which the free end of the air guide fin 30 is closest, such as Figure 2 The second fin 102 is directly opposite to the air guide fin 30 on the middle evaporator 10. The "directly opposite" here means that the air inlet surface of one of the fins is defined between the three air inlet surfaces of the three fins of the evaporator 10. It can also be defined by words such as "facing" and "facing", so that the air inlet surface of the evaporator 10 directly facing the air guide fin 30 is the air inlet surface of one of the fins. The angle specifically refers to: the plane where the extension direction of the air guide fin 30 is located, and the air inlet surface of the evaporator 10 directly facing the air guide fin 30 will form an acute angle and an obtuse angle, or two right angles, and the angle is the acute angle or the right angle.

[0041] In this way, the air guide piece 30 is nearly perpendicular to the side of the evaporator 10 facing it, and can guide the wind to blow vertically toward the evaporator 10, thereby maximizing the utilization rate of the evaporator 10 and ensuring the best cooling effect of the air conditioner.

[0042] Optionally, the number of the air guide blades 30 is 2-5.

[0043] In actual situations, if there are too many air guide plates 30, it will have a greater obstruction to the flow of wind, so that the air volume in the wind flow direction becomes less and less, greatly reducing the utilization rate of the evaporator 10; if the number of air guide plates 30 is too small, it is impossible to fully guide the incoming air to blow to every position of the evaporator 10, and the utilization rate of the evaporator 10 cannot be improved.

[0044] Thus, in the present embodiment, the number of the air guide blades 30 is 2-5, and the number of the air guide blades 30 is moderate, which improves the utilization rate of the evaporator 10 while ensuring that the obstruction to the flow of wind is small.

[0045] Optionally, the number of the air guide blades 30 is 3.

[0046] It has been verified in practice that when the number of the air guide blades 30 is three, the obstruction to the flow of wind is minimal and the incoming wind can be fully guided to blow toward every position of the evaporator 10 .

[0047] In this way, the number of the air guide plates 30 is most appropriate, and the incoming air can be fully guided to blow to each position of the evaporator 10 while minimizing the obstruction to the flow of wind, thereby improving the utilization rate of the evaporator 10.

[0048] Optionally, an air inlet end 202 and an air outlet frame 203 are provided on the middle frame body 20. In the assembled state, along the direction from the air inlet end 202 to the air outlet frame 203, the distance between the air guide plate 30 and the evaporator 10 gradually decreases.

[0049] like Figure 2 As shown, the air inlet end 202 is the left end of the middle frame body 20, and an air inlet grille 204 is provided at the air inlet end 202. The air outlet frame 203 is located at the right end of the middle frame body 20, and an air outlet is provided in the air outlet frame 203. The direction in which the air inlet end 202 points to the air outlet frame 203 can be roughly regarded as the direction from left to right, which can represent the flow direction of the wind. In the flow direction of the wind, if the first air guide plate 30, the second air guide plate 30, ..., the Nth air guide plate 30 are provided in sequence, then the distance between the first air guide plate 30 and the evaporator 10, the distance between the second air guide plate 30 and the evaporator 10, ..., the distance between the Nth air guide plate 30 and the evaporator 10 gradually decreases. The distance between the air guide plate 30 and the evaporator 10 refers to the distance between the free side of the air guide plate 30 and the evaporator 10, which is shown in Figure 2 , is the distance between the free end of the air guide plate 30 and the evaporator 10 .

[0050] In this way, since the air volume gradually decreases along the flow direction of the wind, the distance between adjacent air guide plates 30 and the evaporator 10 gradually decreases. When the air volume is large, the distance between the air guide plates 30 and the evaporator 10 is large, which can ensure that the wind obstruction is small, and ensure that sufficient wind energy is blown to the rear part of the evaporator 10 through the gap between the air guide plates 30 and the evaporator 10, thereby improving the utilization rate of the evaporator 10; when the air volume is small, the distance between the air guide plates 30 and the evaporator 10 is small, and the wind guiding effect of the air guide plates 30 is enhanced, which can ensure that most of the small amount of wind is guided to the evaporator 10 when the air volume is small, thereby improving the utilization rate of the evaporator 10.

[0051] Optionally, the air guide blades 30 are parallel to each other.

[0052] In this way, the air guide blades 30 are parallel to each other, and the changed wind flow directions are also roughly parallel, which can guide the wind to blow evenly toward the evaporator 10, avoid the wind repeatedly blowing toward the same position of the evaporator 10, and further improve the utilization rate of the evaporator 10.

[0053] Optionally, along the direction from the air inlet end 202 to the air outlet frame 203 , the distance between adjacent air guide blades 30 gradually decreases.

[0054] Since the air guide blades 30 are parallel to each other, the spacing between adjacent air guide blades 30 refers to the distance between the plane where one air guide blade 30 is located and the plane where its adjacent air guide blade 30 is located.

[0055] In this way, as the air volume decreases along the wind flow direction, the spacing between adjacent air guide plates 30 gradually decreases, and the air guide plates 30 are distributed more and more densely, which can enhance the wind guiding effect when the air volume is small, and further improve the utilization rate of the evaporator 10.

[0056] Optionally, the length of the air guide plate 30 is not less than the length of the evaporator 10 .

[0057] The length is the length of the air guide fin 30 or the evaporator 10 in the extension direction of the straight section of the copper tube of the evaporator 10. In this way, within the influence range of each air guide fin 30, each air guide fin 30 can guide the wind to blow to all parts of the evaporator 10 in the length direction, further improving the utilization rate of the evaporator 10.

[0058] Optionally, the air guide piece 30 is detachably connected to the middle frame body 20 .

[0059] In this way, it is convenient to disassemble the air guide plate 30, to change the number of the air guide plates 30, and further to change the wind guidance according to the wind volume to ensure a high utilization rate of the evaporator 10; it is also convenient to change and replace the length of the air guide plate 30 according to the length of the evaporator 10, so that the cooperation effect of the air guide plate 30 and the evaporator 10 is better.

[0060] Optionally, a slot is provided on the middle frame body 20, and the air guide piece 30 is suitable for being inserted into the slot. For example, a socket may be provided on the air guide piece 30, and the socket fits with the slot to form a cross connection, so that the connection between the middle frame body 20 and the air guide piece 30 is more stable; a protrusion may also be provided on the air guide piece 30, and the protrusion fits with the slot, so that the air guide piece 30 is convenient to disassemble and assemble, and the air guide piece 30 may be prevented from excessively entering the slot, reducing the air guide area, and thus reducing the air guide effect.

[0061] In this way, the connection structure between the middle frame body 20 and the air guide plate 30 is simple and has low cost; it is also convenient to disassemble the air guide plate 30 and to change the number of the air guide plates 30 .

[0062] Optionally, the air guide piece 30 is integrally formed with the middle frame body 20 .

[0063] Since the air conditioner generates vibration when it is working, if the air guide plate 30 and the middle frame body 20 are detachably connected, noise will be generated at the connection between the air guide plate 30 and the middle frame body 20, reducing the user experience; the vibration will also cause friction at the connection between the air guide plate 30 and the middle frame body 20, reducing the service life of the air guide plate 30.

[0064] In this way, the air guide plate 30 and the middle frame body 20 are integrally formed, the overall structural strength of the air guide structure is high, and the structure is stable; and noise can be avoided at the connection between the air guide plate 30 and the middle frame body 20, thereby improving the service life of the air guide plate 30.

[0065] In a preferred implementation of this embodiment, the two ends of the air guide plate 30 are fixed to the two ends of the hollow grille 201, and the middle part of the air guide plate 30 is fixed to the middle part of the hollow grille 201, or embedded or integrally formed. Preferably, the total length of the air guide plate 30 is 656.5 mm, and the effective length is 642.5 mm. The effective length is the length of the part of the air guide plate 30 that has the function of guiding the wind, so that part of the two ends of the air guide plate 30 is in the hollow grille 201, and does not have the function of guiding the wind, but can enhance the connection firmness between the air guide plate 30 and the middle frame body 20. In this way, the preferred air guide plate 30 of this implementation has a length of 656.5 mm, a width of 16 or 17 cm, and a thickness of 1 cm, which has a significant effect on improving the utilization rate of the evaporator 10.

[0066] This embodiment provides an air conditioner, comprising any one of the above-mentioned air guide structures. The air guide structure comprises a middle frame body 20 and an air guide plate 30, one side of the air guide plate 30 is fixed to the middle frame body 20; when the air guide structure is installed, the air guide plate 30 is located outside the air conditioner evaporator 10, and the other side of the air guide plate 30 faces and is close to the evaporator 10. In the air conditioner, the air guide plate 30 is located on the flow path of the wind, and can guide the wind entering the middle frame body 20 to blow toward the evaporator 10, thereby improving the utilization rate of the evaporator 10 and further improving the cooling effect of the air conditioner.

[0067] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
