DETAILED DESCRIPTION

[0039] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0040] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0042] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components.

[0044] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. The range hood is a common kitchen appliance. The range hood uses a fan to exhaust harmful gases such as oil smoke, fog, and steam generated in the kitchen to the outdoors, keeping the kitchen air fresh, preventing oil smoke from depositing on kitchen walls and furniture, and reducing the harm of oil smoke to the human body and the environment.

[0045] In the related art, the range hood includes a housing, a fan and a decorative cover. The housing has an installation cavity and an inspection port connected to the installation cavity, and the fan is arranged in the installation cavity. The decorative cover is arranged on the periphery of the housing and is fixedly connected to the housing to protect the housing. When the fan fails, it is usually necessary to remove the decorative cover and repair the fan in the housing through the inspection port. The connecting device of the decorative cover is arranged between the housing and the wall.

[0046] However, the decorative cover of the above range hood is not easy to install, resulting in low maintenance and cleaning efficiency of the fan.

[0047] Based on this, see Figure 1 and Figure 2 , Figure 1 This is one of the structural schematic diagrams of a range hood provided in an embodiment of the present application. Figure 2 This is a second structural schematic diagram of a range hood provided in an embodiment of the present application. The present application provides a range hood 1000 , which includes a housing 10 and a fan 20 .

[0048] Specifically, the box body 10 has an installation cavity 101, and is provided with an air inlet 102 and an air outlet 103 communicating with the installation cavity 101. The box body 10 has an installation surface 104, and the installation surface 104 is used to be connected to a wall.

[0049] In some embodiments, the housing 10 is further provided with an inspection port 105, which is in communication with the installation cavity 101. It is understandable that the housing 10 can be opened through the inspection port 105, and the device in the installation cavity 101 can be cleaned, inspected and maintained.

[0050] See also Figure 3 , Figure 3 This is a third structural diagram of a range hood provided in an embodiment of the present application. In some embodiments, a first connecting structure 106 is provided on the housing.

[0051] See again Figure 2 The fan 20 is disposed in the installation cavity 101. The fan 20 is used to drive air flow into the installation cavity 101 through the air inlet 102 and to be discharged through the air outlet 103, thereby reducing indoor air pollution.

[0052] It should be noted that the type of the fan 20 may be a centrifugal fan, an axial flow fan or a mixed flow fan, which may be selected according to actual conditions, and the present application does not make any specific limitation thereto.

[0053] Exemplarily, the present application is described by taking a centrifugal fan 20 as an example.

[0054] The fan 20 includes a motor 201 and an impeller 202. The motor 201 can drive the impeller 202 to rotate, and can discharge the air in the box 10 out of the box 10, thereby generating a negative pressure area in the box 10.

[0055] It should be noted that the type of the range hood 1000 can be a top suction range hood or a side suction range hood, which can be selected according to actual conditions, and this application does not make specific restrictions on this.

[0056] It is understandable that when the range hood 1000 is working, the motor 201 drives the impeller 202 to rotate, so that the impeller 202 can discharge the air in the box to the outside through the smoke outlet, thereby generating a negative pressure area in the box 10. The rising oil smoke can enter the box 10 under the attraction of the negative pressure area. Then, the oil smoke is separated from the oil and gas under the centrifugal action of the impeller 202. The grease particles in the oil smoke are thrown to the inner wall of the oil smoke channel with the help of centrifugal force, condensed into oil droplets and collected through the oil path. The purified smoke is accelerated by the impeller 202 and discharged to the outside.

[0057] See also Figure 3In order to improve the appearance of the range hood 1000 , the range hood 1000 further includes a decorative cover 30 .

[0058] The decorative cover 30 can be arranged on the peripheral side of the box body 10 and shield the inspection opening 105. In this way, the decorative cover 30 can shield the box body 10, making the range hood 1000 more beautiful, and at the same time can shield the inspection opening 105, and play a certain protective role on the inspection opening 105.

[0059] In order to ensure the working efficiency and working effect of the range hood 1000, after the range hood 1000 is used for a period of time, it is necessary to clean and maintain the impeller 202 and the inside of the housing 10. If the range hood 1000 fails, it is also necessary to open the inspection port 105 to inspect the range hood 1000.

[0060] It is understandable that to clean or repair the range hood 1000 , the decorative cover 30 must first be disassembled, and then the device inside the housing 10 must be cleaned or repaired through the inspection port 105 on the housing 10 .

[0061] In some embodiments, see Figure 3 The decorative cover 30 is provided with a second connection structure 301 , and the second connection structure 301 can be detachably connected to the first connection structure 106 .

[0062] In order to facilitate the connection between the second connection structure 301 and the first connection structure 106, a guide channel 107 is provided on one side of the box body 10 close to the decorative cover 30. The guide channel 107 includes a first end 1071 and a second end 1072, and the first end 1071 is located below the second end 1072.

[0063] The second connection structure 301 is located in the guide channel 107 and can slide along the guide channel 107 between the first end 1071 and the second end 1072 so as to connect or separate the second connection structure 301 from the first connection structure 106 .

[0064] It is understandable that, during the assembly of the decorative cover 30 and the housing 10, the guide channel 107 can guide the second connection structure 301 to slide from the second end 1072 to the first end 1071, so that the second connection structure 301 is connected to the first connection structure 106, so that the decorative cover 30 can be installed. During the disassembly of the decorative cover 30 and the housing 10, the second connection structure 301 is separated from the first connection structure 106, and the guide channel 107 can guide the second connection structure 301 to slide from the first end 1071 to the second end 1072, so that the decorative cover 30 can be disassembled. By providing the guide channel 107, the second connection structure 301 can be guided to achieve the connection and separation of the second connection structure 301 and the first connection structure 106, and there is no need to align the second connection structure 301 with the first connection structure 106, thereby improving the installation efficiency of the decorative cover 30. In this way, after the cleaning and maintenance of the fan 20 is completed, it is convenient to install the decorative cover 30 back on the housing, which is conducive to improving the maintenance and cleaning efficiency of the fan 20.

[0065] It should be noted that the guide channel 107 can be located on the installation surface 104 of the box body 10, or on the side of the box body 10. It can be specifically arranged according to the actual needs, and this application does not make any specific restrictions on this.

[0066] It should be noted that the guide channel 107 can be vertically arranged or inclined, and can be arranged according to the actual needs, and the present application does not impose any specific restrictions on this.

[0067] For example, see Figure 3 The guide channel 107 is arranged vertically, which is convenient for processing.

[0068] It should be noted that the first connection structure 106 can be located at the first end 1071 or at other positions of the box body 10. It can be specifically configured according to actual needs, and the present application does not impose any specific restrictions on this.

[0069] For example, see Figure 3 The first connecting structure 106 may be located at the first end 1071. Such a configuration can simplify the structure of the range hood 1000 and facilitate processing and manufacturing.

[0070] In some embodiments, see Figure 4 , Figure 4This is one of the structural schematic diagrams of a decorative cover provided in an embodiment of the present application. The decorative cover 30 includes a panel 302 and two side panels 303. The panel 302 is arranged opposite to the mounting surface 104 and is located on the side of the box 10 away from the mounting surface 104. The two side panels 303 are arranged on the side of the panel 302 close to the box 10 and are connected to the panel 302. The two side panels 303 are arranged opposite to each other, and the box 10 is located between the two side panels 303. In this way, the two side panels 303 and the panel 302 can surround the box 10, which has a better protection and decorative effect on the box 10.

[0071] A second connection structure 301 is provided on each side plate 303, and one second connection structure 301 corresponds to one guide channel 107, and a first connection structure 106 is provided at a first end 1071 of one guide channel 107. The second connection structure 301 can slide along the corresponding guide channel 107, so that the second connection structure 301 is connected to or separated from the corresponding first connection structure 106.

[0072] It can be understood that the second connecting structures 301 are respectively provided on the two side panels 303, one second connecting structure 301 corresponds to one guide channel 107, and a first connecting structure 106 is provided at the first end 1071 of a guide channel 107, which can fix the decorative cover 30 on both sides of the range hood 1000, thereby making the connection between the decorative cover 30 and the box body 10 more stable.

[0073] In some embodiments, see Figure 4 The side panel 303 includes a side panel 3031 and a first flange 3032. The side panel 3031 is connected to the panel 302. The first flange 3032 is arranged at an end of the side panel 3031 away from the panel 302, and the first flange 3032 is arranged opposite to the panel 302. In this way, the panel 302, the side panel 3031 and the first flange 3032 surround the box body 10, and the first flange 3032 is connected to the installation surface 104 of the box body 10, which can limit the movement of the decorative cover 30 relative to the box body 10 in a direction perpendicular to the installation surface 104.

[0074] It should be noted that the first connection structure 106 can be set as a connection hole 1061 or a clamping groove, and the second connection structure 301 can be set as a matching claw 3011 or a clamping column. The first connection structure 106 can also be set as a clamping block, and the second connection structure 301 can be set as a matching clamping groove. The specific settings can be made according to the actual needs, and this application does not make specific restrictions on this.

[0075] For example, see Figure 5 , Figure 5 for Figure 3In the partial enlarged structural diagram at A in the middle, the second connection structure 301 includes a claw 3011, which is located at the lower side of the first flange 3032 and connected to the first flange 3032. Figure 6 , Figure 6 for Figure 3 In the partial enlarged structural diagram at B, the first connection structure 106 includes a connection hole 1061. It can be understood that the claw 3011 can be engaged in the connection hole 1061.

[0076] In this way, the claw 3011 is engaged in the connection hole 1061 to realize the connection between the first connection structure 106 and the second connection structure 301 , which has a simple structure, saves materials, and is easy to process.

[0077] In some embodiments, see Figure 4 Combined with Figure 7 , Figure 7 for Figure 4 In the partial enlarged structural diagram at C in the middle, the claw 3011 includes a first sub-plate 3012 and a second sub-plate 3013. The first sub-plate 3012 is connected to the first flange 3032. The second sub-plate 3013 is connected to an end of the first sub-plate 3012 away from the first flange 3032, and the end of the second sub-plate 3013 away from the first sub-plate 3012 is inclined relative to the first sub-plate 3012 toward the direction close to the panel 302.

[0078] It can be understood that the end of the second sub-plate 3013 away from the first sub-plate 3012 is tilted relative to the first sub-plate 3012 in the direction close to the panel 302, which enables the second sub-plate 3013 to easily enter the connecting hole 1061 when sliding from the second end 1072 to the first end 1071 along the guide channel 107, thereby allowing the entire claw 3011 to be engaged in the connecting hole 1061.

[0079] In some embodiments, see Figure 4 Combined with Figure 7 The end of the first sub-board 3012 away from the second sub-board 3013 is inclined relative to the second sub-board 3013 toward the panel 302. The ends of the first sub-board 3012 and the second sub-board 3013 that are close to each other abut against the box body 10.

[0080] It can be understood that the end of the first sub-board 3012 away from the second sub-board 3013 is tilted relative to the second sub-board 3013 toward the panel 302, so that the ends of the first sub-board 3012 and the second sub-board 3013 that are close to each other form abutment. When the claw 3011 is engaged in the connecting hole 1061, the ends of the first sub-board 3012 and the second sub-board 3013 that are close to each other abut against the box body 10, which can limit the movement of the decorative cover 30 relative to the box body 10, making the connection between the decorative cover 30 and the box body 10 more stable.

[0081] In some embodiments, see Figure 8 Combined with Fig. 9 , Figure 8 This is a fourth structural schematic diagram of a range hood provided in an embodiment of the present application. Fig. 9 for Figure 8 In the partial enlarged structural diagram at D in the middle, the range hood 1000 further includes an oil-proof cover 40. The oil-proof cover 40 is located in the installation cavity 101, connected to the box body 10, and covered on the connection hole 1061.

[0082] It is understandable that due to the operation of the range hood 1000, a certain amount of oil will be generated inside the housing 10. Since the connection hole 1061 is located on the housing 10, the oil inside the housing 10 may flow to the outside of the housing 10 through the connection hole 1061, causing the outside of the housing 10 to be dirty. By providing an oil-proof cover 40 covering the connection hole 1061, the problem of oil inside the housing 10 flowing out through the connection hole 1061 can be reduced.

[0083] In some embodiments, see Fig.10 , Fig.10 This is a second structural schematic diagram of a decorative cover provided in an embodiment of the present application. The side panel 303 also includes a connecting plate 3033 , and the connecting plate 3033 is connected to the first flange 3032 .

[0084] The connecting plate 3033 may be located in the guide channel 107 and may slide along the guide channel 107. Both ends of the connecting plate 3033 in the arrangement direction of the two side plates 303 are in contact with the inner wall of the guide channel 107.

[0085] It can be understood that the two ends of the connecting plate 3033 in the arrangement direction of the two side panels 303 contact with the inner wall of the guide channel 107 to limit the movement of the decorative cover 30 relative to the box body 10 along the arrangement direction of the two side panels 303, further limiting the movement direction of the decorative cover 30, and making the connection between the decorative cover 30 and the box body 10 more stable.

[0099] In some embodiments, the smoke hood 70 further includes a back plate 704, which is partially connected to the mounting surface 104 and has a second flange 7041. When the second connection structure 301 is connected to the first connection structure 106, at least a portion of the first flange 3032 abuts against the second flange 7041.

[0100] In this way, the connection between the smoke hood 70 and the box body 10 can be made more stable through the abutment between the first flange 3032 and the second flange 7041 .

[0101] See also Fig.14 The range hood 1000 further includes a control panel 80 , which is disposed on the periphery of the fume collecting hood 70 and is used to control the operation of the range hood 1000 .

[0102] It can be understood that the control panel 80 is the main control center for users to operate the range hood 1000. Users can conveniently control various functions of the range hood 1000 through the control panel 80, thereby further improving the convenience and comfort of kitchen use.

[0103] It should be noted that the control panel 80 can be a glass panel or a plastic panel, which can be selected according to actual conditions, and this application does not make any specific restrictions on this.

[0104] It can be understood that the installation process of the decorative cover 30 is as follows: the decorative cover 30 is lifted and installed vertically downward from the upper part of the box body 10, and the claw 3011 moves along the second end 1072 of the guide channel 107 to the first end 1071 in the guide channel 107. The first flange 3032 contacts the second flange 7041, and the decorative cover 30 continues to move downward. The second sub-plate 3013 of the claw 3011 enters the connecting hole 1061, and the end where the first sub-plate 3012 and the second sub-plate 3013 are connected abuts against the box body 10, fixing the decorative cover 30 on the box body 10. At the same time, the lower part of the decorative cover 30 enters the installation opening of the smoke hood 70 and abuts against the limiting structure 703. At this time, the fixing hole 3034 is concentric with the avoidance hole 108, and the decorative cover 30 is fixed to the box body 10 using the fastener 50.

[0105] The disassembly process of the decorative cover 30 is as follows: after the fastener 50 is disassembled, the decorative cover 30 is lifted upwards to separate the decorative cover 30 from the box body 10 .
