Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, fig. 1 schematically shows that the air guiding device 100 includes an air guiding plate 1 and an air guiding driving mechanism 2.
In the embodiment of the present application, the air guide plate 1 is generally installed below the case of the air conditioner 200 for opening and closing the duct outlet 10 as described below.
The air guiding plate 1 has a pivot shaft 11, wherein, it should be noted that, one end of the pivot shaft 11 is fixedly connected with the air guiding plate 1, and the other end is connected with a connecting rod assembly 22 described below.
A wind guide driving mechanism 2 is provided at an end of a base plate of an air conditioner 200 (see fig. 3), and the wind guide driving mechanism 2 is used to drive a wind guide plate 1 to open or close a wind duct outlet 10 as described below. The air guide driving mechanism 2 includes a driving shaft 21, a link assembly 22, a first sliding chute 23, and a sliding rod 24 slidably engaged with the first sliding chute 23, wherein one end of the link assembly 22 is fixedly connected to the driving shaft 21, and the other end is hinged to the pivot shaft 11 through the sliding rod 24. The driving shaft 21 may be mechanically connected to the rotating mechanism, so that the driving shaft 21 can rotate correspondingly under the driving of the rotating mechanism. Since the driving shaft 21 is fixedly connected to one end of the connecting rod assembly 22, the rotation of the driving shaft 21 can drive the connecting rod assembly 22 to rotate.
In a specific embodiment, the rotating mechanism may be a motor or other device having a power transmission.
The specific opening process of the air deflector 1 is as follows: the driving shaft 21 drives the connecting rod assembly 22 to rotate, and the connecting rod assembly 22 rotates to drive the sliding rod 24 to move along the first sliding chute 23, so that the opening position of the air deflector 1 is located on the extension line of the air duct outlet 10 of the air conditioner 200. Specifically, the air deflector 1 can be positioned on an extension line of the air duct outlet 10 under the driving action of the air guiding driving mechanism 2, which is equivalent to extending the air duct, and can greatly increase the air supply distance of hot air, thereby greatly accelerating the indoor heat exchange efficiency.
As shown in fig. 1 and 2, in order to further optimize the air deflector 1 in the above-mentioned technical solution, on the basis of the above-mentioned technical solution, the surface of the air deflector 1 facing the air duct outlet 10 is configured as an outer convex surface 12. In the conventional air conditioner 200, when the heating mode is turned on, since the density of the hot air is low, the hot air flow blown out from the duct outlet 10 easily flows upward in the room, and it is difficult to deliver the hot air flow to the bottom of the room, resulting in uneven indoor temperature. However, the present application can provide the air guiding function by disposing the air deflector 1 at the end of the chassis of the air conditioner 200, and at the same time, by configuring the surface of the air deflector 1 facing the air duct outlet 10 as the outer convex surface 12, the air flow blown out from the air duct outlet 10 can flow along the convex profile of the air deflector 1 of the air duct outlet 10 under the "coanda effect", which becomes more obvious with the increase of the "convexity" of the outer convex surface 12. That is, after the hot air flow is separated from the air duct outlet 10 by using the coanda effect, the original flowing direction of the hot air flow is changed to the direction flowing along the surface of the convex object, that is, the hot air flow can flow downwards along the outer convex surface 12, so that the hot air flow is blown to the indoor bottom, the indoor temperature rise speed is obviously increased, the indoor temperature is uniformly distributed, and the comfort is brought to a user.
In one specific embodiment, the outer convex surface 12 is a circular arc surface. That is to say, the surface of the air deflector 1 facing the air duct outlet 10 is configured as an arc surface, which is not only beneficial to the flow of hot air, but also can play a role in conveying hot air to the indoor bottom. The arc surface is relative to the convex surface with the edge angle, so that hot air can flow more smoothly, and flowing obstacles to the flowing hot air are avoided.
As shown in fig. 1, in the embodiment of the present application, the link assembly 22 includes a first link 221 and a second link 222, wherein one end of the first link 221 is fixedly connected to the driving shaft 21, the other end is hinged to a first end 222a of the second link 222, and a second end 222b of the second link 222 is hinged to the pivot shaft 11 through the sliding rod 24. In this way, the driving shaft 21 drives the first connecting rod 221 and the second connecting rod 222 to rotate, so as to indirectly drive the sliding rod 24 to move in the first sliding slot 23, and further, the sliding rod 24 drives the pivoting shaft 11 to rotate, so as to open and close the air deflector 1.
As shown in fig. 1, in the embodiment of the present application, a first through hole 222c is formed at the second end 222b of the second link 22, and a second through hole is formed on the pivot 11, and the first through hole 222c matches with the second through hole and together forms a combined mounting hole for the slide rod 24 to pass through. Specifically, the second link 222 is hinged to the pivot shaft 11 by passing one end of the slide rod 24 through the combination mounting hole and into the first slide groove 23.
As shown in fig. 1, in one embodiment of the present application, the air guiding device 100 further includes a box 3 installed outside the housing of the air conditioner 200, and the air guiding driving mechanism 2 is located inside the box 3. Like this, through installing this wind-guiding actuating mechanism 2 in box body 3 for this wind-guiding actuating mechanism 2 becomes the modularization, makes things convenient for this wind-guiding actuating mechanism 2's installation and dismantlement, and simultaneously, this box body 3 also can play certain guard action to wind-guiding actuating mechanism 2, avoids leading to the unable normal condition of working of wind-guiding actuating mechanism 2 because of receiving the interference of colliding with or other parts in the external world.
In a preferred embodiment of the present application, a second sliding slot 31 is formed on the bottom wall of the box body 3, which matches the first sliding slot 23, wherein the first sliding slot 23 and the second sliding slot 31 are arranged opposite to each other up and down and together form a channel for the sliding rod 24 to slide. The slide rail is arranged to prevent the slide rod 24 and the connecting rod assembly 22 from shaking during movement, so as to ensure the smooth operation of the air guide driving mechanism 2.
As shown in fig. 3, fig. 3 schematically shows that the air deflector 1 hermetically covers the air duct outlet 10 of the air conditioner 100. Specifically, the air guide driving mechanism 2 of the present application is located outside the housing of the air conditioner 200, so that the air guide plate 1 can completely seal the air duct outlet 10 when closed under the driving of the air guide driving mechanism 2, thereby ensuring the overall aesthetic property of the air conditioner 200.
As shown in fig. 2, in a preferred embodiment of the present application, when the open position of the air deflector 1 is located on an extension of the air duct outlet 10 of the air conditioner 200, the air deflector 1 configures the air duct outlet 10 as a divergent opening 10 a. Specifically, when the air deflector 1 is located on the extension line of the air duct outlet 10, the air duct outlet 10 and the air deflector 1 jointly form the gradually expanding opening 10a, when the air flow passes through the gradually expanding section, the flow speed of the air flow is slowed down, and the resistance of the cross-sectional air flow overcoming the ambient air environment is increased, so that the air flow is blown farther, the indoor heat exchange is accelerated, and the indoor heat exchange efficiency is improved.
As shown in fig. 4, according to a second aspect of the present application, there is also provided an air conditioner 200, where the air conditioner 200 includes the above-mentioned air guiding device 100.
In summary, the air deflector 1 in the air guiding device 100 of the present application can be located on the extension line of the air duct outlet 10 under the driving action of the air guiding driving mechanism 2, which is equivalent to extending the air duct, and can greatly increase the air supply distance of hot air, thereby greatly increasing the indoor heat exchange efficiency.
Furthermore, by configuring the surface of the air deflector 1 facing the air duct outlet 10 as the outer convex surface 12, the air flow blown out from the air duct outlet 10 can flow along the convex profile of the air deflector 1 of the air duct outlet 10 under the "coanda effect", which becomes more obvious as the degree of "convexity" of the outer convex surface 12 increases. That is, after the hot air flow is separated from the air duct outlet 10 by the coanda effect, the original flowing direction of the hot air flow is changed to the direction flowing along the surface of the convex object, that is, the hot air flow can flow downwards along the outer convex surface 12, so that the hot air flow is blown to the indoor bottom, the indoor temperature rise speed is obviously improved, the indoor temperature is uniformly distributed, and the comfort is brought to users.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
