Description

Technical Field

[0001] The invention relates to an air outlet structure. Background Art

[0002] As people's living standards improve, they have higher and higher requirements for kitchen working temperature. They need refrigeration range hoods to cool down the kitchen to improve the user experience when cooking. The blowing angle and air outlet speed of refrigeration range hoods play a key role in the user experience. Therefore, a good air outlet solution can improve the user experience and enhance product competitiveness. The cold air outlet of the existing refrigeration range hood is located on the upper part of the kitchen cabinet door, and the blowing direction is horizontal. The cold air cannot reach people, resulting in poor user experience. If the air outlet angle is adjusted so that people are blown by the wind, a large change in the air outlet angle will cause wind field disturbance, thereby affecting the fume extraction effect. In summary, the existing air outlet structure needs to be further improved. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an air outlet structure with multiple air outlet modes and adjustable air outlet angles in view of the above-mentioned existing technical status.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the air outlet structure includes an air outlet frame, the air outlet frame has an air outlet, and is characterized in that: an air guide cover and an air guide plate are installed on the air outlet frame, the air guide cover and the air guide plate rotate relative to the air outlet frame under the drive of a driving mechanism, and an air outlet hole is opened on the air guide plate, and the air outlet structure has an air outlet closed state, a windless air outlet state and a normal air outlet state. In the air outlet closed state, the air guide cover and the air guide plate are hidden in the air outlet frame and the air guide plate covers the air outlet. In the windless air outlet state, the air guide cover and the air guide plate rotate outwards to the same angle relative to the air outlet frame, and air is discharged only through the air outlet holes of the air guide plate. In the normal air outlet state, the rotation angle of the air guide plate relative to the air outlet frame is greater than the rotation angle of the air guide cover relative to the air outlet frame and the air guide plate can swing, forming an air outlet channel between the air guide plate and the air guide cover.

[0005] In order to limit the rotation angle of the air guide cover, a limiting structure for limiting the maximum rotation angle of the air guide cover is provided between the air outlet frame and the air guide cover. In the windless air outlet state and the normal air outlet state, the air guide cover rotates to the maximum rotation angle.

[0006] In order to prevent the air guide cover from rotating too much and blocking the upward air outlet direction, the maximum rotation angle of the air guide cover is 40° to 50°.

[0007] Preferably, the maximum rotation angle of the wind deflector is 120° to 150°, so as to avoid wind field disturbance caused by too large change of wind outlet angle.

[0008] The driving mechanism may have various structures. Preferably, the driving mechanism includes a first motor for driving the air guide cover to rotate and a second motor for driving the air guide plate to rotate.

[0009] In order to improve the structural strength of the wind shield, the wind guide plate includes an wind guide panel and an wind guide lining plate arranged on the back of the wind guide panel. When the air outlet is closed, the wind guide lining plate is hidden inside the air outlet frame, and the wind guide panel covers the air outlet.

[0010] Further preferably, when the air outlet is closed, the air guide panel is in a vertical position. In this way, the air guide panel completely covers the air outlet of the air outlet frame, and only the air guide panel is exposed outside, and the overall structure is very simple.

[0011] In order to ensure uniform air outlet in a windless air outlet mode, the air outlet holes are provided on the air guide lining plate and the air guide panel, and the air outlet holes on the air guide panel are evenly spaced and have the same aperture.

[0012] Further preferably, the diameter of the air outlet holes on the air guide panel is 3 to 5 mm.

[0013] As a preferred solution, a sealing plate that can rotate relative to the air outlet frame is installed on the air outlet frame. When the air outlet is closed, the sealing plate rotates upward to the front of the air outlet frame and covers the air guide panel. In the windless air outlet state and the normal air outlet state, the sealing plate rotates downward to the bottom of the air outlet frame or rotates upward to the top of the air outlet frame.

[0014] As another preferred scheme, a sealing plate that can translate relative to the air outlet frame is installed on the air outlet frame. When the air outlet is closed, the sealing plate translates to the front of the air outlet frame and covers the air guide panel. In the windless air outlet state and the normal air outlet state, the sealing plate translates to the bottom or top of the air outlet frame.

[0015] As a preferred embodiment of any of the above schemes, the air outlet frame, the air guide cover and the air guide plate are all in the shape of long strips.

[0016] Compared with the prior art, the advantages of the present invention are: when the air outlet is closed, the air guide cover and the air guide plate are hidden in the air outlet frame and the air guide plate covers the air outlet of the air outlet frame, thereby ensuring the beauty of the overall appearance; in the windless air outlet state, the air guide cover and the air guide plate are rotated outward to the same angle relative to the air outlet frame, and air is only discharged through the air outlet holes of the air guide plate; in the normal air outlet state, the rotation angle of the air guide plate is greater than the rotation angle of the air guide cover, thereby forming an air outlet channel between the air guide plate and the air guide cover, and the air guide plate can swing to form a swing mode, and the air outlet direction can be adjusted as needed, thereby improving comfort.

[0027] The present invention is further described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1:

[0029] like Figures 1 to 7 As shown, the air outlet structure of the present embodiment includes an air outlet frame 1, and the air outlet frame 1 has an air outlet 11. An air guide cover 2 and an air guide plate 3 are installed on the air outlet frame 1, and the air outlet frame 1, the air guide cover 2 and the air guide plate 3 are all in the shape of long strips. The air guide cover 2 rotates relative to the air outlet frame 1 under the drive of the first motor, and the air guide plate 3 rotates relative to the air outlet frame 1 under the drive of the second motor. The maximum rotation angle of the air guide cover 2 is 40° to 50°, and the angle value can be selected according to the actual state. The maximum rotation angle of the air guide plate 3 is 120° to 150°, and the angle value can be selected according to the actual state. There is a limiting structure 5 between the air outlet frame 1 and the air guide cover 2 for limiting the maximum rotation angle of the air guide cover 2. The limiting structure 5 of the present embodiment adopts a limiting block, see Figure 5 .

[0030] The air guide plate 3 includes an air guide panel 31 and an air guide lining 32 arranged on the back of the air guide panel 31. Air outlet holes 30 are opened on the air guide lining 32 and the air guide panel 31. The air outlet holes 30 on the air guide panel 31 are evenly spaced and have the same aperture. In order to achieve windless air outlet, the aperture of the air outlet holes 30 on the air guide panel 31 is 3 to 5 mm.

[0031] like Figure 2 and Figure 2 As shown, the air outlet structure is in a closed air outlet state, at which time, the air guide cover 2 and the air guide lining 32 are hidden inside the air outlet frame 1, and the air guide panel 31 is in a vertical position and covers the air outlet 11, ensuring the beauty of the overall appearance.

[0032] like Figure 4 and Figure 5 As shown, the air outlet structure is in a windless air outlet state, and the air guide cover 2 and the air guide plate 3 are rotated outward, i.e. clockwise, to the same angle relative to the air outlet frame 1. At this time, the air guide cover 2 is rotated to the maximum rotation angle A, and the air outlet structure can only discharge air through the air outlet hole 30 of the air guide panel 31.

[0033] like Figure 6 and Figure 7 As shown, the air outlet structure is in a normal air outlet state, the air guide cover 2 rotates clockwise to the maximum rotation angle A, the rotation angle of the air guide plate 3 relative to the air outlet frame 1 is greater than the maximum rotation angle of the air guide cover 2, and an air outlet channel 4 is formed between the air guide plate 3 and the air guide cover 2, and the air outlet structure discharges air through the air outlet channel 4. In this state, the air guide plate 3 can stay at a certain rotation angle to form a fixed air outlet angle, usually, the air guide plate 3 stays at the maximum rotation angle B; it can also swing back and forth to form a swing wind mode, in which the air guide plate 3 swings back and forth within the rotation angle range of A to B.

[0034] The air outlet structure of this embodiment can be applied to the air outlet of an air conditioner, the air outlet of an internal unit of a refrigeration range hood, or other machines that require air outlet. When the air outlet structure is applied to a refrigeration range hood, it is usually installed on the top of the range hood. When the air conditioner is not turned on, the air guide cover 2 and the air guide plate 3 are both in a closed state, and the air guide cover 2 and the air guide plate 3 are both turned back to the vertical position to ensure the beauty of the overall appearance. When the air conditioner is turned on, the user can choose from three air outlet modes: no wind mode, cold wind mode, and swing wind mode. When the no wind mode is selected, the air guide cover 2 and the air guide plate 3 both rotate clockwise at an angle A, and the cold air is blown out through the air outlet 30 on the air guide panel 31; when the cold wind mode is selected, the air guide cover 2 rotates clockwise at an angle A, and the air guide plate 3 rotates clockwise at an angle B; when the swing wind mode is selected, the air guide cover 2 rotates clockwise at an angle A, and the air guide plate 3 rotates clockwise at an angle B, and the air guide plate 3 swings back and forth within the angle range of A to B, which solves the problem that the cold air of the refrigeration range hood cannot reach people, improves the cooking comfort, and the swing wind angle is controlled within a certain range, which will not cause wind field disturbance due to excessive changes in the air outlet angle, thereby affecting the range fumes extraction effect.

[0035] Embodiment 2:

[0036] The air outlet structure of this embodiment is provided with a sealing plate 6 mounted on the air outlet frame, and the sealing plate 6 is rotatably connected to the air outlet frame 1. Figure 8 As shown, when the air outlet is closed, the sealing plate 6 is flipped upward to the front of the air outlet frame 1 and covers the air guide panel 31. Fig. 9 As shown, in the windless air outlet state, the sealing plate 6 is flipped downward to the bottom of the air outlet frame 1. Fig.10 As shown, in the normal air outlet state, the sealing plate 6 flips downward to the bottom of the air outlet frame 1. The remaining structures of this embodiment are the same as those of the first embodiment and will not be described in detail here. In addition, the sealing plate 6 can also move in translation relative to the air outlet frame. In the air outlet closed state, the sealing plate 6 moves in translation to the front of the air outlet frame 1 and covers the air guide panel 31. In the windless air outlet state and the normal air outlet state, the sealing plate 6 moves in translation to the bottom or top of the air outlet frame 1.
