[0029] ​​For the purposes of the present application, the solutions and the advantageous effects thereof will be made clearer in the light of the attached drawings and preferred embodiments.

[0030] An embodiment of the range hood according to the present application is shown in Figure 1 , comprising a smoke collecting cavity 1 and a smoke guide plate 2 detachably mounted in front of the smoke collecting cavity 1, an air inlet 11 is formed between the opening of the smoke collecting cavity 1 and the smoke guide plate 2 for the smoke to enter, and a casing (not shown) containing a fan is arranged above the smoke collecting cavity 1.

[0031] The opening of the smoke collecting cavity 1 is provided with a hanger 3, as shown in Figure 2 . The smoke guide plate 2 is provided with a hook assembly 4 detachably connected with the hanger 3, as shown in Figure 3 . The hook assembly 4 comprises a first hanging plate 41 extending from the back of the smoke guide plate 2, and a first hook 42 formed at the end of the first hanging plate 41 away from the smoke guide plate 2. The first hook 42 is configured to cooperate with the hanger 3 to limit the displacement of the smoke guide plate 2 in the y direction, and the first hanging plate 41 is configured to cooperate with the hanger 3 to limit the displacement of the smoke guide plate 2 in the z direction. Wherein, the y direction and the z direction are respectively the depth direction and the height direction of the range hood. In this way, through the cooperation of the hanger 3 and the hook assembly 4, the smoke guide plate 2 can be positioned in the depth direction and the height direction without the aid of screw connection and the like when installed.

[0032] For the sake of clarity, Figure 1 , an xyz coordinate system is given, in which the width direction x, the depth direction y and the vertical direction z of the range hood are shown in the conventional state, two by two perpendicular to each other.

[0033] Optionally, the hook assembly 4 further comprises a hook fixing plate 43 connected to the back of the smoke guide plate 2, and the first hanging plate 41 extends backward from the hook fixing plate 43.

[0034] Further, as shown in Figure 7 , the hanger 3 is provided with a clamping opening 31 for the hook assembly 4 to pass through, and the hook assembly 4 is aligned with the clamping opening 31 and sent backward into the hanger 3 when the smoke guide plate 2 is installed, and the installation is realized through the cooperation of the two. The clamping opening 31 is arranged on the hanger 3 and faces the smoke guide plate 2, and in an optional embodiment, after installation is completed, the first hanging plate 41 abuts the lower edge of the clamping opening to realize positioning in the z direction due to gravity, and the first hook 42 abuts the rear wall of the hanger 3 to realize positioning in the y direction, and in this embodiment, the extension length of the first hanging plate 41 in the y direction is equal to or slightly greater than the thickness of the clamping opening 31.

[0035] According to an exemplary embodiment of the present application, as shown in Figure 8As shown, the hanger 3 is provided with an elastic fastener 32, which is configured to press the hook assembly 4 against the clamping opening 31 along the z direction, thereby further enhancing the stability of the smoke deflector 2 in the vertical direction.

[0036] In order to better cooperate with the elastic fastener 32, in an alternative embodiment, the elastic fastener 32 is located above the hook assembly 4, and the hook assembly 4 further comprises a second hanging plate 44 extending from the back of the smoke deflector 2, and a second hook 45 formed at the end of the second hanging plate 44 away from the smoke deflector 2. During the installation of the smoke deflector 2, as shown in Figure 5 the second hook 45 and the second hanging plate 44 successively contact and press upward against the elastic fastener 32, and after the installation is completed, as shown in Figure 6 the elastic fastener 32 is still pressed by the second hanging plate 44 and is in a compressed state, and the second hanging plate 44 is therefore subjected to an upward reaction force from the elastic fastener 32, that is, the smoke deflector 2 is also pressed downward on the hanger 3. Further, the upper edge of the hanger 3 is provided with a flange 33 extending rearward along the y direction, and the elastic fastener 32 is arranged on the flange 33.

[0037] It can be understood that the second hanging plate 44 is higher than the first hanging plate 41 in the z direction, and the height difference therebetween should satisfy that when the first hanging plate 41 is pressed downward against the lower edge of the clamping opening 31, the second hanging plate 44 can press upward against the elastic fastener 32 to keep it in an elastic compression state.

[0038] In an alternative embodiment, as shown in Figure 9 the elastic fastener 32 is a spring latch, which comprises a few-shaped pin body 321, a plug rod 322, a limiting boss 323, and a spring 324. The pin body 321 comprises two bottom surfaces and a top surface, and the two bottom surfaces are respectively provided with connecting holes. The flange 33 is also provided with connecting structures at positions corresponding to the connecting holes, so that the pin body 321 and the flange 33 can be directly connected by means of screws or the like.

[0039] Further, the top surface of the pin body 321 is provided with a through hole 325, the plug rod 322 cooperates with the through hole 325 and penetrates through the pin body 321, and the bottom end of the plug rod 322 protrudes downward from the flange 33. The limiting boss 323 is arranged on the plug rod 322 and located within the pin body 321, and the spring 324 is sleeved on the plug rod 322, with the two ends of the spring 324 abutting against the inner wall of the pin body 321 and the limiting boss 323, respectively. During the installation of the smoke deflector 2, the second hook 45 presses the bottom end of the plug rod 322 and makes it move upward, and the spring 324 is therefore pressed by the limiting boss 323 and is in an elastic compression state. Preferably, the bottom end of the plug rod 322 is provided with a chamfer, and the bending degree of the second hook 45 should be such that the surface thereof can cooperate with the chamfer to achieve upward pushing of the plug rod 322.

[0040] According to an example embodiment of the present application, as shown in Figure 6 and Figure 7 the lower edge of the clamping opening 31 is provided with a clamping piece 311 extending rearward along the y direction, the first hanging plate 41 abuts against the extending surface of the clamping piece 311, and the first hook 42 abuts against the end of the clamping piece 311 away from the clamping opening 31, thereby respectively limiting the displacement of the smoke guide plate 2 in the z direction and the y direction. In this embodiment, the extending length of the first hanging plate 41 in the y direction is equal to or slightly greater than the extending length of the clamping piece 311 in the y direction. The provision of the clamping piece 311 increases the abutting area of the first hanging plate 41, making the positioning in the z direction more stable.

[0041] According to an example embodiment of the present application, the first hanging plate 41 is configured to cooperate with the clamping opening 31 to limit the displacement of the smoke guide plate 2 in the x direction; wherein the x direction is the width direction of the range hood. Optionally, one clamping opening 31 corresponds to one first hanging plate 41, and the extending length of the first hanging plate 41 in the x direction is equal to or slightly greater than the extending length of the clamping opening 31 in the x direction; or as shown in Figure 3 , one clamping opening 31 corresponds to two first hanging plates 41, and the distance between the two edges of the two first hanging plates 41 farthest in the x direction is equal to or slightly greater than the extending length of the clamping opening 31 in the x direction.

[0042] According to an example embodiment of the present application, the hanger 3 is arranged along the x direction and the number is two, respectively located at different heights of the smoke collecting cavity 1; the hook assembly 4 is arranged on the smoke guide plate corresponding to the hanger 3; wherein the x direction is the width direction of the range hood. In an optional embodiment, as shown in Figure 4 , the back surface of the smoke guide plate 2 is provided with two hook assemblies 4 along the x direction, each hook assembly 4 is provided with at least one first hanging plate 41 and first hook 42 corresponding to the upper and lower hangers 3, respectively, and the mounting cooperation of multiple points makes the structure of the range hood more stable.

[0043] Based on the mounting structure of the smoke guide plate 2 described above, the mounting method of the smoke guide plate 2 in this embodiment includes the following steps:

[0044] S1: roughly align the hook assembly 4 on the smoke guide plate 2 with the clamping opening 31 of the hanger 3;

[0045] S2: move the smoke guide plate 2 rearward along the y direction, so that the second hook 45 and the second hanging plate 44 abut against and press the insertion rod 322 in turn, so that the spring 324 is elastically deformed;

[0046] S3: lower the smoke guide plate 2 so that the first hanging plate 41 abuts against the lower edge of the clamping opening 31 or the clamping piece 311, that is, the installation is completed.

[0047] The dismounting method of the smoke guide plate 2 in this embodiment includes the following steps:

[0048] S1: move the smoke guide plate 2 upward to overcome the force from the spring;

[0049] S2: move the smoke guide plate 2 forward along the y direction, i.e. complete disassembly.

[0050] The components of different embodiments can be combined in any feasible way to achieve the purposes of the present application.
