Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] The directions mentioned below are in the form of Figure 1 The orientation of each component is used as a reference.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides an air guiding device for a portable air conditioner, comprising an outer frame 1, a ventilation cavity 11 disposed in the outer frame 1, a first air guiding structure 2 disposed in the middle of the ventilation cavity 11, the first air guiding structure 2 comprising at least one first air guiding port 21, the multiple first air guiding ports 21 being arranged sequentially from the inside to the outside, one side of the first air guiding port 21 being the air inlet side, the other side of the first air guiding port 21 being the air outlet side, the cross-sectional area of ​​the first air guiding port 21 gradually increasing from the air inlet side to the air outlet side, adjacent first air guiding ports 21 being connected by a first connecting plate 22, and the outermost first air guiding port 21 being rotatably connected to the side wall of the ventilation cavity 11 by a first connecting shaft 23; The outer frame 1 is also provided with a fixed power transmission structure, which is connected to the first connecting shaft 23. The fixed power transmission structure enables the first air guide structure 2 to rotate back and forth around the central axis of the first connecting shaft 23 and fix the first air guide structure 2 at any angle. The angle refers to the angle between the initial position of the first air guide structure 2 and its position after rotation.

[0019] Specifically, the first air guide vent 21 guides the airflow from the air conditioner. The first air guide vent 21 has a hollow structure, and its cross-sectional shape can be quadrilateral, pentagonal, hexagonal, etc., to facilitate its manufacturing and ensure its performance. Figure 1 As shown, the cross-sectional shape of the first air guide 21 of this utility model is preferably rectangular, and adjacent sides of the rectangle are connected by a circular arc transition.

[0020] The first air guiding structure 2 preferably includes two layers of first air guiding ports 21, with the inner first air guiding port 21 located in the center of the outer first air guiding port 21.

[0021] The air outlet of a portable air conditioner is usually located in the upper middle part of the front of the cabinet. In order to ensure the effectiveness of the air guiding device of this utility model, the first air guiding structure 2 is set vertically and the first connecting shaft 23 is set horizontally. This setting allows the fixed power transmission structure to make the first air guiding structure 2 rotate back and forth in the vertical direction, thereby improving the large-angle air delivery range of the portable air conditioner in the vertical direction.

[0022] The function of the fixed power transmission structure is to enable the first air guide structure 2 to rotate back and forth around the central axis of the first connecting shaft 23. A preferred structure of the first air guide structure 2 of this utility model is as follows: (Example...) Figure 1 , Figure 3 As shown, the fixed power transmission structure includes a handle 31, a rack 32, and a gear 33. A first rotating hole is provided on one side wall of the ventilation cavity 11, and a vertically oriented strip hole 12 is provided on the front of the outer frame 1. The rack 32 is vertically arranged, and the gear 33 meshes with the rack 32. One end of the first connecting shaft 23 passes through the first rotating hole and is connected to the gear 33. One end of the handle 31 is connected to the rack 32, and the other end of the handle 31 passes through the strip hole 12 to the outside of the outer frame 1. The handle 31 can move up and down in the strip hole 12. The working principle of the first air guiding structure 2 is as follows: when the handle 31 moves up and down in the strip hole 12, it drives the rack 32 to move up and down. The up and down movement of the rack 32 drives the gear 33 to rotate. The rotation of the gear 33 drives the first connecting shaft 23 to rotate. The rotation of the first connecting shaft 23 drives the first air guiding structure 2 to rotate back and forth. The first air guide structure 2 is simple in structure and easy to use. By utilizing the self-locking property of the gear 33 and the rack 32, the first air guide structure 2 can maintain its rotated state for a long time, ensuring the effectiveness of the first air guide structure 2.

[0023] A portion of the first connecting shaft 23 is located in the ventilation cavity 11. The first connecting shaft 23 sometimes also plays a role in guiding airflow. To improve the airflow guiding effect of the first connecting shaft 23, the first connecting shaft 23 includes a first shaft part and a first plate part connected together. A gear 33 is mounted on the first shaft part, which passes through a first rotating hole. The first plate part is connected to the first air guide port 21. The first shaft part is cylindrical in shape to facilitate its rotation, and the first plate part is rectangular in shape to facilitate its airflow guiding.

[0024] To improve the stability of the first air guide structure 2 during use and increase its overall strength, for example... Figure 1As shown, this utility model also includes a horizontally arranged second connecting shaft 24. A second through hole or rotating groove is provided on the other side wall of the ventilation cavity 11. The first connecting shaft 23 and the second connecting shaft 24 are respectively arranged on both sides of the first air guiding structure 2. The second connecting shaft 24 includes a second shaft part and a second plate part connected together. The second plate part is connected to the first air guide port 21. The second shaft part is rotatably disposed in the second through hole or rotating groove. The second shaft part is cylindrical in shape to facilitate its rotation, and the second plate part is rectangular in shape to facilitate its air guiding.

[0025] To make it easier for users to operate, the rotation angle of the first air guide structure 2 needs to be limited, for example... Figure 1 , Figure 3 As shown, a limiting post is provided on the second rotating shaft, and an arc-shaped limiting hole or arc-shaped limiting groove 13 is provided on the other side wall of the ventilation cavity 11. The limiting post is movably disposed in the arc-shaped limiting hole or arc-shaped limiting groove 13. The limiting post and the arc-shaped limiting hole or arc-shaped limiting groove 13 form a limiting structure, so that the first air guiding structure 2 can only rotate within the range limited by the arc-shaped limiting hole or arc-shaped limiting groove 13.

[0026] To improve the horizontal airflow range of portable air conditioners, for example... Figure 1 As shown, the outer frame 1 contains multiple ventilation chambers 11 arranged side-by-side along the width direction. A first air guide structure 2 or a second air guide structure 4 is located in the middle of each ventilation chamber 11. The second air guide structure 4 includes at least one layer of second air guide vents 41, with multiple layers of second air guide vents 41 spaced apart from the inside out. One side of each second air guide vent 41 is the air inlet side, and the other side is the air outlet side. From the air inlet side to the air outlet side, the cross-sectional area of ​​the second air guide vent 41 gradually increases. Adjacent second air guide vents 41 are connected by a second connecting plate 42. The outermost second air guide vent 41 is connected to the sidewall of the ventilation chamber 11 by a third connecting plate 43. The second air guide vents 41 of the second air guide structure 4 are fixed. When multiple ventilation chambers 11 are provided, the first air guide structure 2 or the second air guide structure 4 are used in conjunction. This arrangement not only increases the air delivery range of the air conditioner but also reduces manufacturing costs and improves the overall strength of the air guide device.

[0027] For example Figure 4 As shown, the portable air conditioner includes a cabinet 5 with an air outlet, and also includes the aforementioned air guide device. The air guide device is either fitted into the air outlet or fitted to the outside of the air outlet. Fitting the air guide device into the air outlet can be used for newly designed portable air conditioners, while fitting it to the outside of the air outlet can be used for improvements to already manufactured portable air conditioners.
