Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a flow guiding structure and an air conditioner. Background Art

[0002] At present, there are more and more types of cabinet air conditioners on the market, among which centrifugal cabinet air conditioners are widely used. Since the air outlet of the centrifugal fan assembly of the air conditioner cabinet is set upward, the airflow is thrown out from the volute air outlet and blown upward, and enters the room from the side air outlet. In order to allow the airflow to be blown out from the side air outlet grille, a guide plate is set at the air outlet of the centrifugal fan assembly, but the existing guide plate has a poor guiding effect and is prone to generate air duct noise. Summary of the invention

[0003] In order to solve the technical problem of poor air guide effect of the air conditioner in the prior art, the present invention provides an air guide structure and an air conditioner.

[0004] The technical solution adopted by the present invention is:

[0005] The present invention proposes a guide structure, comprising: a guide plate arranged at the air outlet of a fan, the guide plate being arranged in an air outlet cavity, the guide plate being inclined toward the air outlet side of the air outlet cavity and bent into multiple sections to form a guide air duct that guides air toward the air outlet side.

[0006] The guide plate includes: a first guide plate and a second guide plate which are spaced apart and arranged in parallel, and a guide air duct which is connected to the air outlet of the fan is formed between the first guide plate and the second guide plate.

[0007] The guide plate is bent into a first inclined section and a second inclined section, the first inclined section is connected to the air outlet, the second inclined section is connected to the first inclined section, and the inclination angle of the second inclined section relative to the horizontal plane is smaller than the inclination angle of the first inclined section relative to the horizontal plane.

[0008] Preferably, the angle A between the first inclined section and the horizontal plane is in the range of 65°≤A≤85°.

[0009] Preferably, the angle α between the second inclined section and the horizontal plane is in the range of 25°≤α≤35°.

[0010] Preferably, a distance D between the first guide plate and the second guide plate is in the range of 60 mm ≤ D ≤ 85 mm.

[0011] Furthermore, the first guide plate is away from the air outlet side of the air outlet cavity relative to the second guide plate, and the first guide plate is bent into a first inclined section, a second inclined section and a third inclined section, the inclination angle of the second inclined section relative to the horizontal plane is smaller than the inclination angle of the first inclined section relative to the horizontal plane, and the inclination angle of the third inclined section relative to the horizontal plane is smaller than the inclination angle of the second inclined section relative to the horizontal plane.

[0012] Furthermore, an air outlet grille is provided on the air outlet side of the air outlet cavity.

[0013] The present invention also proposes an air conditioner, comprising the above-mentioned flow guiding structure.

[0014] The air conditioner specifically comprises: a shell, a transverse partition which divides the shell into an air outlet cavity and the heat exchange cavity, the fan and the heat exchanger installed in the heat exchange cavity, and an opening corresponding to the fan air outlet is provided on the transverse partition.

[0015] Compared with the prior art, the present invention arranges a guide plate in the air outlet of the cabinet corresponding to the fan outlet. The guide plate is inclined toward the air outlet side of the air outlet cavity and bent into multiple sections to make the air outlet path smoother and reduce wind resistance. Wind can be blown out evenly from the air outlet grille on the air outlet side of the air outlet cavity, avoiding most of the airflow from impacting the top of the air outlet cavity and then flowing out, thereby reducing air outlet noise.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown, the present invention proposes a guide structure, which is arranged in the air outlet cavity 2 of the housing 6 of the cabinet, and specifically includes a guide plate. The bottom of the air outlet cavity 2 is connected to the air outlet of the fan 4, and the side is provided with an air outlet grille 3, which can discharge air from the side. The guide plate is connected to the position of the air outlet at the bottom of the air outlet cavity 2 to guide the wind from the air outlet of the fan 4 to the air outlet side of the air outlet cavity 2. The guide plate is inclined toward the air outlet side of the air outlet cavity and bent into multiple sections, so that the air outlet path is smoother and the wind resistance is reduced. The wind can be evenly blown out from the air outlet grille on the air outlet side, avoiding that most of the airflow hits the top of the air outlet cavity before flowing out, thereby reducing the air outlet noise.

[0023] The guide plate includes: a first guide plate 11 and a second guide plate 12, which are spaced apart and arranged in parallel to form a guide air duct between the first guide plate 11 and the second guide plate 12. The interval D between the first guide plate 11 and the second guide plate 12 is in the range of 60 mm ≤ D ≤ 85 mm, so that the wind pressure is moderate and turbulence is avoided in the air outlet cavity.

[0024] In one embodiment, the first guide plate 11 and the second guide plate 12 are both bent into two sections (specifically taking the first guide plate in the figure as an example), namely a first inclined section 111 and a second inclined section 112. The first inclined section 111 is connected to the air outlet of the fan 4, and the second inclined section 112 is connected to the first inclined section 111. The inclination angle of the second inclined section 112 relative to the horizontal plane is smaller than the inclination angle of the first inclined section 111 relative to the horizontal plane, that is, the guide plate is gradually inclined toward the air outlet side. By setting multiple inclined sections with different angles, it is avoided that the inclination angle is too large to cause excessive wind resistance and generate noise.

[0025] The range of the angle A between the first inclined section 111 and the horizontal plane is 65°≤A≤85°, and the specific value is 80 degrees, which is slightly inclined toward the air outlet side to avoid excessive wind resistance at the air outlet. The range of the angle α between the second inclined section 112 and the horizontal plane is 25°≤α≤35°, which is relative to not setting a wind deflector.

[0026] In a specific application, through simulation of air volume calculation, it is found that when the angle α between the second inclined section 112 and the horizontal plane is set to 35°, the air volume increase can reach 7% compared with not setting the second inclined section. When the angle α between the second inclined section 112 and the horizontal plane is set to 25°, the air volume increase can reach 3% compared with not setting the second inclined section, which greatly improves the air outlet efficiency and reduces the air outlet noise.

[0027] In order to further improve the wind guiding effect, in the second embodiment, the first guide plate 11 is bent into a first inclined section 111, a second inclined section 112 and a third inclined section 113. The first guide plate 11 is away from the wind outlet side of the wind outlet cavity relative to the second guide plate 12, and the third inclined section 113 is inclined at an angle of less than 25° relative to the horizontal plane. This prevents the airflow from blowing directly to the top of the wind outlet cavity to generate noise, and at the same time makes the direction of the airflow as perpendicular to the wind outlet side as possible to improve the wind outlet efficiency.

[0028] The present invention also proposes an air conditioner, comprising a shell 6, wherein the above-mentioned guide structure is installed in the air outlet cavity 2 of the shell 6, and a transverse partition 61 is provided in the shell 6 to divide the internal space of the shell 6 into an air outlet cavity 2 located at the upper part and a heat exchange cavity located at the lower part of the shell, and a fan 4 and a heat exchanger 5 are installed in the heat exchange cavity. The fan can specifically be a centrifugal fan, and an opening corresponding to the fan outlet is provided on the transverse partition, so that the fan outlet can pass through the partition and extend into the air outlet cavity.

[0029] The air conditioner may specifically be a marine water-cooled cabinet unit, and the guide structure enables the marine water-cooled cabinet unit to further develop in the direction of light weight and low noise.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
