Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air guide ring and electric control box assembly, a ceiling unit and an air conditioner. Background Art

[0002] As people's requirements for quality of life are getting higher and higher, air conditioners have become an indispensable household appliance. There are many types of air conditioners. Ceiling air conditioners, also known as patio air conditioners or ceiling-mounted and embedded air conditioners; ceiling air conditioners can save space and are more beautiful, and are widely used in large places.

[0003] However, ceiling air conditioners make relatively loud noise during actual operation, which affects the user experience. Summary of the invention

[0004] The present invention solves the problem that the ceiling air conditioner has relatively large noise and poor user experience during actual operation.

[0005] In order to solve the above problems, the present invention provides an air guide ring and an electric control box assembly for a ceiling machine, comprising: an air guide ring, a middle part of which is provided with an air guide channel and an air guide side; an electric control box, connected to the air guide ring at the air guide side; an inner side panel of the electric control box is provided on the side of the electric control box close to the air guide channel; wherein the distance from the inner side panel of the electric control box to the center of the air guide channel is greater than the radius of the air guide channel; the distance from the middle part of the inner side panel of the electric control box to the center of the air guide channel is less than the distance from the opposite ends of the inner side panel of the electric control box to the center of the air guide channel.

[0006] Compared with the prior art, the present invention sets the distance from the inner side plate of the electric control box to the center of the air guide channel to be greater than the radius of the air guide channel, so as to prevent the electric control box from covering part of the air guide channel, causing uneven airflow flowing into the air guide channel, outputting biased flow and causing strong noise. At the same time, the distance from the middle of the inner side plate of the electric control box to the center of the air guide channel is smaller than the distance from the opposite ends of the inner side plate of the electric control box to the center of the air guide channel, thereby expanding the inflow space of the airflow from the opposite ends of the inner side plate of the electric control box to the air guide channel, reducing the airflow resistance at the opposite ends, and then reducing the ventilation resistance on the air guide side, so that the airflow flowing into the air guide channel is more uniform, further reducing the noise generated during the operation of the air conditioner, and improving the user experience.

[0007] In an optional embodiment, the inner side plate of the electric control box is a curved surface.

[0008] It can be understood that the setting of the curved surface has a guiding effect, which is beneficial to air circulation, reduces circulation resistance, and thus reduces noise.

[0009] In an optional embodiment, along the direction from the middle of the inner side plate of the electric control box to the opposite end, the distance between the inner side plate of the electric control box and the center of the air guide channel gradually increases.

[0010] It can be understood that it can expand the air flow space, increase the air flow volume, and improve the air supply of air conditioning.

[0011] In an optional embodiment, the distances from the two opposite ends of the inner plate of the electric control box to the center of the air guide channel are equal.

[0012] It can be understood that the airflow introduced into the air guide channel on both sides is made relatively uniform, thereby avoiding deviation of the air flow in the air guide channel.

[0013] In an optional embodiment, the distance from the side of the inner plate of the electric control box away from the air guide ring to the center of the air guide channel is greater than the distance from the other side of the inner plate of the electric control box close to the air guide ring to the center of the air guide channel.

[0014] It can be understood that the inner side plate of the electric control box is tilted away from the air guide ring on one side and away from the air guide ring on the other side of the inner side plate of the electric control box close to the air guide ring; the amount of air flowing in from the inner side plate of the electric control box away from the air guide ring is increased, thereby improving the operating efficiency of the air conditioner.

[0015] In an optional embodiment, the distance from the inner side plate of the electric control box away from the air guide ring to the center of the air guide channel gradually decreases to the distance from the inner side plate of the electric control box close to the air guide ring to the center of the air guide channel.

[0016] It can be understood that this is convenient for increasing the effective flow of the air conditioner and increasing the air supply of the air conditioner; at the same time, it makes the inclined surface of the inner panel of the electric control box relatively smooth, thereby reducing the air flow resistance, making the air flow relatively uniform and smooth, and avoiding turbulence in the air flow flowing into the air guide channel.

[0017] In an optional embodiment, there is an inclination angle between the inner side plate of the electric control box and the air guide ring; and the inclination angle decreases successively along the direction from the middle of the inner side plate of the electric control box toward both ends.

[0018] It can be understood that the inclination angle decreases successively along the direction from the middle of the inner panel of the electric control box toward the two ends, thereby expanding the inflow space of the airflow flowing into the air guide channel from the two ends, reducing the airflow flow resistance at the two ends, making the airflow in the air guide channel more uniform, and reducing the operating noise of the air conditioner; at the same time, the inclination direction of the inner panel of the electric control box is consistent, and the middle part of the inner panel of the electric control box is more inclined relative to the two ends, which promotes the Coanda effect, so that the airflow flowing in from the two ends of the inner panel of the electric control box flows more toward the center of the air guide channel, reducing noise while increasing the effective flow of airflow.

[0019] In an optional embodiment, the included angle between the cut angle at the end of the inner plate of the electric control box and the vertical direction is greater than the included angle between the cut angle at the middle of the inner plate of the electric control box and the vertical direction.

[0020] It can be understood that the two ends of the inner plate of the electric control box are flatter than the middle surface, so that the airflow flowing in from the two ends of the inner plate of the electric control box can be gathered to the middle of the inner plate of the electric control box and flow into the center of the air guide channel, increasing the effective flow rate.

[0021] The present invention further provides a ceiling machine, comprising the air guide ring and the electric control box assembly described in any one of the above embodiments.

[0022] The present invention further provides an air conditioner, comprising the air guide ring and the electric control box assembly described in any one of the above embodiments, or comprising the ceiling air conditioner described in the above embodiments.

[0023] The present invention has the following beneficial effects:

[0024] 1) The air conditioner has low noise and high operating efficiency;

[0025] 2) Small air flow resistance, uniform air flow, and large effective air flow;

[0026] 3) The airflow is relatively uniform and smooth, and the airflow flowing into the air guide channel is not prone to turbulence. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In existing ceiling air conditioners, since the electronic control box contains many electrical components, part of the outer contour of the electronic control box often covers part of the air guide channel, making the airflow into the air guide channel uneven and causing biased flow, which can easily cause serious noise problems and greatly affect the user experience.

[0034] To this end, the purpose of an embodiment of the present invention is to provide an air guide ring and an electric control box assembly for use in a ceiling air conditioner, which can make the airflow into the air guide channel uniform and prevent deviation, thereby avoiding noise generation and improving the user experience.

[0035] 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.

[0036] [Example 1]

[0037] See also Figure 1 This embodiment provides an air guide ring and an electric control box assembly for a ceiling machine 300 , and the air guide ring and the electric control box assembly includes: an air guide ring 200 and an electric control box 100 .

[0038] For details, see Figure 1 An air guide channel 210 and an air guide side (not shown in the figure) are provided in the middle of the air guide ring 200; an electric control box 100 is connected to the air guide ring 200 at the air guide side; an electric control box inner plate 110 is provided on the side of the electric control box 100 close to the air guide channel 210; wherein, a distance rd1 from the electric control box inner plate 110 to the center of the air guide channel 210 is greater than a radius r0 of the air guide channel 210; to prevent the electric control box 100 from covering part of the air guide channel 210, causing uneven airflow into the air guide channel 210, producing biased flow and causing strong noise.

[0039] The distance rd1 from the middle of the inner plate 110 of the electric control box to the center of the air guide channel 210 is smaller than the distances rd2 and rd4 from the opposite ends of the inner plate 110 of the electric control box to the center of the air guide channel 210. The inflow space of the airflow from the opposite ends of the inner plate 110 of the electric control box to the air guide channel 210 is expanded, the airflow resistance at the opposite ends is reduced, and then the ventilation resistance on the air guide side is reduced, so that the airflow in the air guide channel 210 is more uniform, the noise generated during the operation of the air conditioner is further reduced, and the user experience is improved.

[0040] [Example 2]

[0041] See also Figure 2The inner plate 110 of the electric control box is an arc-shaped surface. By providing the inner plate 110 of the electric control box with an arc-shaped surface, the airflow can flow along the wall surface of the inner plate 110 of the electric control box and gather at the concave part of the arc-shaped surface, thereby reducing the airflow resistance, accelerating the air flow, and making it have a guiding effect, which is beneficial to the air circulation inside the air guide channel 210, so as to reduce noise.

[0042] Of course, the inner plate 110 of the electric control box may also be a bent surface, and the bent surface may be an arc-shaped surface in the middle, and the parts extending toward both ends may be straight surfaces at least toward one end, preferably straight surfaces extending symmetrically toward both ends, which will not be elaborated here.

[0043] Furthermore, along the direction from the middle of the inner plate 110 of the electric control box to the opposite end, the distance between the inner plate 110 of the electric control box and the center of the air guide channel 210 gradually increases.

[0044] It can be understood that the distance between the inner panel 110 of the electric control box and the center of the air guide channel 210 is gradually increased from the middle of the inner panel 110 of the electric control box to the opposite end; the air flow space at both ends of the inner panel 110 of the electric control box is expanded, the overall air flow volume is increased, and the air supply volume of the air conditioner is improved.

[0045] Furthermore, the distances from the two opposite ends of the inner side plate 110 of the electric control box to the center of the air guide channel 210 are equal, so that the airflow introduced into the air guide channel 210 from both sides is relatively uniform, and the airflow in the air guide channel 210 is prevented from being biased.

[0046] [Example 3]

[0047] See also Figure 3 The distance rd3 from the side of the inner plate 110 of the electric control box away from the air guide ring 200 to the center of the air guide channel 210 is greater than the distance rd1 from the other side of the inner plate 110 of the electric control box close to the air guide ring 200 to the center of the air guide channel 210. The side of the inner plate 110 of the electric control box away from the air guide ring 200 is tilted away from the air guide ring 200 relative to the other side of the inner plate 110 of the electric control box close to the air guide ring 200; the amount of air flowing in from the side of the inner plate 110 of the electric control box away from the air guide ring 200 is increased, thereby improving the operating efficiency of the air conditioner.

[0048] For further information, see Figure 3 , the inner side plate 110 of the electric control box is an inclined surface.

[0049] Specifically, the distance from the side of the inner plate 110 of the electric control box away from the air guide ring 200 to the center of the air guide channel 210 gradually decreases from the other side of the inner plate 110 of the electric control box close to the air guide ring 200 to the center of the air guide channel 210. This makes the inclined surface of the inner plate 110 of the electric control box relatively smooth, thereby reducing the air flow resistance, making the air flow relatively uniform and smooth, and avoiding the air flow in the air guide channel 210 from being turbulent.

[0050] Furthermore, there is an inclination angle between the inner plate 110 of the electric control box and the air guide ring 200 ; the inclination angle decreases in sequence from the middle of the inner plate 110 of the electric control box toward both ends.

[0051] It can be understood that the inclination angle of the middle part of the inner plate 110 of the electric control box is greater than the inclination angle of the end part of the inner plate 110 of the electric control box, and the inclination angle from the middle part to the end part of the inner plate 110 of the electric control box decreases in a decreasing pattern, thereby avoiding the inclination angle of the inner plate 110 of the electric control box from the end part to the middle part being too undulating, causing the airflow to flow through the surface of the inner plate 110 of the electric control box better against the wall, resulting in a decrease in the effective airflow in the center of the air guide channel 210;

[0052] At the same time, the inclination angle decreases in a decreasing pattern from the middle to the end of the inner panel 110 of the electric control box, thereby expanding the inflow space of the airflow from the two ends into the air guide channel 210, reducing the airflow flow resistance at the two ends, making the airflow in the air guide channel 210 more uniform, and reducing the operating noise of the air conditioner; at the same time, the inclination direction of the inner panel 110 of the electric control box is consistent, and the middle part of the inner panel 110 of the electric control box is more inclined relative to the two ends, which promotes the Coanda effect, so that the airflow flowing in from the two ends of the inner panel 110 of the electric control box flows more toward the center of the air guide channel 210, reducing noise while increasing the effective flow of airflow.

[0053] For further information, see Figure 3 and Figure 4 The included angle β between the cut angle at the end of the inner plate 110 of the electric control box and the vertical direction is greater than the included angle α between the cut angle at the middle of the inner plate 110 of the electric control box and the vertical direction. The two ends of the inner plate 110 of the electric control box are flatter than the surface at the middle, so that the airflow flowing in from the two ends of the inner plate 110 of the electric control box can be gathered to the middle of the inner plate 110 of the electric control box and flow into the center of the air guide channel 210, thereby increasing the effective flow rate.

Compared with the existing ceiling machines, the ceiling machine 300 provided in this embodiment reduces the air flow resistance during actual application, and can increase the amount of air flow; at the same time, it reduces the ventilation resistance on the air guide side, so that the air flow in the air guide channel is more uniform, reduces the noise generated by the ceiling machine 300 during operation, and improves the user experience.

[0057] This embodiment further provides an air conditioner, comprising the air guide ring and electric control box assembly described in any one of the above-mentioned embodiments 1 to 3, or the ceiling unit 300 of the fourth embodiment.
