[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 9 As shown, the internal filter disassembly structure of the range hood of this embodiment includes the main components of the air outlet frame 1, the internal unit 2, the internal filter 3, and the filter cover 4. Among them, the internal unit 2 is located at the rear side of the air outlet frame 1, the internal filter is installed on the top of the internal unit 2, the air outlet frame 1 is provided with a filter disassembly window 11, the filter cover 4 can be detachably installed in the filter disassembly window 11, and the filter cover 4 is located in front of the internal filter 3 to cover the internal filter 3. Figure 2 The direction indicated by the middle arrow A is the forward direction. When the filter cover 4 is removed, the internal filter 3 can be pulled outward to the front side of the air outlet frame 1 through the filter disassembly window 11 or pushed inward to the rear side of the air outlet frame 1.

[0026] The filter cover 4 is detachably connected to the air outlet frame 1. The specific disassembly structure is as follows: a limiting rib 12 and a supporting step 14 are provided at the bottom of the filter disassembly window 11. The limiting ribs are provided on the supporting step 14 and are spaced apart from each other. In this embodiment, there are three limiting ribs 12, and a clamping portion 13 is provided at the top of the filter disassembly window 11; a resisting portion 41 for resisting the limiting rib 12 is provided at the bottom of the filter cover, and a buckle 42 for buckling with the clamping portion 13 is provided at the top of the filter cover 4. During installation, the bottom of the filter cover 4 is supported on the support step 14 and the abutment portion 41 abuts against the limiting rib 12, which facilitates the positioning of the filter cover 4 during installation and improves the installation efficiency of the filter cover 4; the buckle 42 is fastened to the clamping portion 13. In this embodiment, the left and right widths of the buckle 42 are not less than 20 mm, which is convenient for users to disassemble. The left and right sides of the buckle 42 and the corresponding sides of the clamping portion 13 are both interference fit, and the interference amount is 1 to 1.5 mm to ensure that the buckle 42 can be fastened. During disassembly, as long as force is applied to disengage the buckle 42 from the clamping portion 13, the filter cover 4 can be removed from the air outlet frame 1, which is very convenient to disassemble.

[0027] In this embodiment, buckles 21 are spaced apart in the front-to-back direction on both the left and right sides of the top of the indoor unit 2, and the indoor unit filter 3 is clamped in the buckles 21. In addition, guide grooves distributed in the front-to-back direction may also be provided on the left and right sides of the top of the indoor unit 2, and the guide grooves may guide the front-to-back movement of the indoor unit filter 3. When replacing the indoor unit filter 3, first remove the filter cover 4 from the air outlet frame 1, then pull the indoor unit filter 3 to be replaced horizontally forward through the filter disassembly window 11, then push the new indoor unit filter 3 backward through the filter disassembly window 11 to the top of the indoor unit 2, and fasten the indoor unit filter 3 with the buckle 21, and finally, buckle the filter cover 4 on the air outlet frame 1.
