The air conditioning components are added on the platform of the range hood, which can realize all the functions of the range hood and the function of the air conditioning. The refrigeration range hood is mainly divided into a range hood module and a refrigeration module. The cold air outlet of the refrigeration module is arranged on the front side of the top of the refrigeration range hood. Because the cold air outlet is in the kitchen environment, after the refrigeration range hood is used for a long time, the cold air outlet will be attached with oil and dirt, and the air outlet panel needs to be cleaned. In order to adjust the air outlet direction, an air guide plate is generally installed on the air outlet panel. After the air guide plate is removed, it is more convenient to clean the air outlet panel. The current air guide plate disassembly structure of the refrigeration range hood needs to use a tool to push the shaft out vigorously before the air guide plate can be disassembled. Not only is the disassembly inconvenient, but the shaft is also easily broken. In addition, the driving motor of the air guide plate is located on one side, and the torque on both sides of the air guide plate is inconsistent, resulting in uneven appearance gap between the air guide plate and the air outlet frame. In summary, the air outlet panel structure of the existing range hood needs to be further improved. Utility Model Content

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 5As shown, the air outlet panel structure of the range hood of this embodiment includes an air outlet frame 1 and an air guide plate 2 installed on the air outlet frame 1. The air outlet frame 1 and the air guide plate 2 are both in the shape of long strips. The air guide plate 2 swings relative to the air outlet frame 1 under the drive of the driving mechanism. The driving mechanism of this embodiment includes a motor 4 installed in the middle position in the length direction of the air outlet frame 1. The output shaft of the motor 4 is connected to the air guide plate 2 through a transmission assembly. The transmission assembly includes a rotating shaft 5 and a connecting rod 6. The first end of the rotating shaft 5 is installed on the output shaft of the motor 4. The first end of the rotating shaft 5 is rotatably connected to one end of the connecting rod 6. The second end of the connecting rod 6 is connected to the air guide plate 2. As shown in FIG. Fig.10 As shown, the first and second ends of the connecting rod 6 are both provided with an elastic shaft 61, and the elastic shaft 61 is provided with a U-shaped groove 62. The U-shaped groove 62 can ensure the installation and removal of the elastic shaft 61. In order to prevent the connecting rod 6 from being loosened from the rotating shaft and the connecting rod 6 from being loosened from the air guide plate 2, an anti-loosening buckle 63 is provided at the end of the U-shaped groove 62. Thus, the motor 4 is connected to the air guide plate 2 through the rotating shaft 5 and the connecting rod 6, and the connection position is located in the middle position of the air guide plate 2, so that the rotation torque at both ends of the air guide plate 2 is consistent, so that the appearance gap between the two ends of the air guide plate 2 and the air outlet frame 1 is uniform.

[0029] like Figure 6 As shown, the air outlet frame 1 is provided with a mounting shaft hole 11. In this embodiment, there are 5 mounting shaft holes 11 spaced apart along the length direction of the air outlet frame 1. A mounting shaft 3 is installed in each mounting shaft hole 11. The air guide plate 2 is detachably mounted on the mounting shaft 3 and can rotate synchronously with the mounting shaft 3. The air guide plate 2 is limited on the mounting shaft 3 by a limiting structure and is locked on the mounting shaft 3 by a locking structure.

[0030] like Figure 7 and Figure 8 As shown, the air guide plate 2 is provided with a limiting rib 21, a limiting buckle 22, a front limiting baffle 23, a rear limiting baffle 24, a guide rib 25, etc., wherein the limiting rib 21 and the limiting buckle 22 are arranged between the front limiting baffle 23 and the rear limiting baffle 24. The front limiting baffle 23 is adjacent to the mounting shaft hole 11, and a positioning shaft hole 231 is opened on the front limiting baffle 23. The front end of the mounting shaft 3 is a connecting shaft 30. When the air guide plate 2 is installed, the connecting shaft 30 is inserted into the positioning shaft hole 231 and the mounting shaft hole 11. The limiting rib 21 is arranged at the rear side of the front limiting baffle 23, and the limiting buckle 22 is located at the rear side of the limiting rib 21. A guide rib 25 is arranged between the front limiting baffle 23 and the rear limiting baffle 24. In this embodiment, there are two guide ribs 25, and the limiting rib 21 and the limiting buckle 22 are located on the outer side of the corresponding side guide rib 25.

[0031] like Figure 7 and Fig. 9As shown, the two opposite sides of the installation shaft 3 are elastic ribs 31 that can be deformed under the action of external force, the outer wall of the elastic rib 31 is convexly provided with a limiting protrusion 32, the bottom of the installation shaft 3 is formed with a guide groove 33 that matches the guide rib 25, the front end of the installation shaft 3 has a connecting shaft 30, and the rear end of the installation shaft 3 has a disassembly buckle 34 that protrudes upward. When the air guide plate 2 is installed, the limiting rib 21 on the air guide strip 2 is arranged on the outer side of the corresponding side elastic rib 31 and abuts against the elastic rib 31, the limiting buckle 22 is arranged on the outer side of the corresponding side elastic rib 31 and buckled on the elastic rib 31, the elastic rib 31 and the limiting rib 21 constitute a limiting structure, and the elastic rib 31 and the limiting buckle 22 constitute a locking structure. In addition, the limiting protrusion 32 is arranged on the front side of the limiting buckle 22, and in order to enable the installation shaft 3 to be disassembled smoothly, a disassembly gap is left between the rear end of the installation shaft 3 and the rear limiting baffle 24.

[0032] When installing the air guide plate 2, firstly, the elastic rib 31 of the installation shaft 3 is deformed, and the installation shaft 3 is placed on the air guide plate 2. The guide groove 33 of the installation shaft 3 is guided and matched with the guide rib 25 on the air guide plate 2, so that the installation shaft 3 can move between the front limit baffle 23 and the rear limit baffle 24 of the air guide plate 2 along the direction set by the guide rib 25, and the limit rib 21 and the limit buckle 22 are arranged on the outside of the elastic rib 31. Then, the installation shaft 3 is moved in the direction of the front limit baffle 23, and the limit protrusion 32 is deformed and rebounds after passing through the limit buckle 22. At this time, the limit protrusion is located at the front side of the limit buckle 22, which can prevent the installation shaft 3 from moving in the direction of the rear limit baffle 24. The connecting shaft 30 of the installation shaft 3 passes through the positioning shaft hole 231 on the front limit baffle 23 of the air guide plate 2 and the installation shaft hole 11 of the air outlet frame 1, and the front end of the installation shaft 3 can be against the front limit baffle 23 to prevent the installation shaft 3 from moving forward further.

[0033] When removing the air guide plate 2, external force is applied to the disassembly buckle 334 of the mounting shaft 3, and the mounting shaft 3 moves toward the rear limit baffle 24. The limit protrusion 32 of the mounting shaft 3 will be deformed and pass through the limit buckle 22, so that the connecting shaft 30 of the mounting shaft 3 is disconnected from the mounting shaft hole 11 of the air outlet frame 1.

[0034] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
