Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a range hood. Background Technology

[0002] Range hoods operate on the principles of fluid dynamics. They consist of a main body and a smoke collection chamber assembly. The suction force generated by the main body draws the cooking fumes into the smoke collection chamber, from where the hood is then exhausted outdoors. However, the main body and smoke collection chamber assembly in these technologies are not convenient for users to replace or clean later. Summary of the Invention

[0003] This application provides a range hood that allows users to easily replace and clean the main body or smoke collection chamber components later.

[0004] In a first aspect, embodiments of this application provide a range hood; the range hood includes a main body, a smoke collection chamber assembly, and a connector. The main body includes a main housing and a fan assembly. The main housing has a receiving cavity, and the fan assembly is disposed in the receiving cavity. The smoke collection chamber assembly is spaced apart from the main body. The smoke collection chamber assembly includes a smoke collection chamber housing, which has a smoke collection chamber and a first smoke inlet communicating with the smoke collection chamber. The connector is detachably connected to both the main body and the smoke collection chamber assembly, and the connector has an air duct communicating with the air inlet of the smoke collection chamber and the fan assembly.

[0005] The range hood based on the embodiments of this application is equipped with a connector, which is detachably connected to the main body of the range hood and the smoke collection chamber assembly, making it convenient for users to replace and clean the main body of the range hood or the smoke collection chamber assembly in the future. At the same time, the connector also forms an air duct for the circulation of oil fumes.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Range hoods work by utilizing the principles of fluid dynamics. A range hood consists of a main body and a smoke collection chamber assembly. The suction force generated by the main body draws the cooking fumes into the smoke collection chamber assembly, and then the main body discharges the fumes outdoors.

[0020] However, in the relevant technologies, the main body of the range hood and the smoke collection chamber assembly are not detachable, which means that if either the main body of the range hood or the smoke collection chamber assembly is damaged, it cannot be replaced separately, and it is also not conducive to cleaning the main body of the range hood and the smoke collection chamber assembly.

[0021] To solve the above technical problems, please refer to Figures 1-2 As shown, the first aspect of this application proposes a range hood 1, which includes a range hood body 10, a smoke collection chamber assembly 20, and a connector 30. The smoke collection chamber assembly 20 is spaced apart from the range hood body 10. The connector 30 is detachably connected to both the smoke collection chamber assembly 20 and the range hood body 10. The connection between the connector 30 and both the smoke collection chamber assembly 20 and the range hood body 10 enables the connection between the smoke collection chamber assembly 20 and the range hood body 10, achieving an integrated structural design for the range hood 1. The detachable connection of the connector 30 to both the smoke collection chamber assembly 20 and the range hood body 10 facilitates the user's later replacement and cleaning of the smoke collection chamber assembly 20 and the range hood body 10, reducing maintenance costs and difficulty.

[0022] The range hood body 10 includes a main housing 11 and a fan assembly 12. The main housing 11 forms a receiving cavity 111, and the fan assembly 12 is disposed in the receiving cavity 111. The smoke collection chamber assembly 20 includes a smoke collection chamber housing 21, which forms a smoke collection chamber 211 and a first smoke inlet 212 communicating with the smoke collection chamber 211. The connector 30 forms an air duct 353 communicating with the air inlet of the smoke collection chamber 211 and the fan assembly 12. Thus, when the range hood 1 is in use, the fan assembly 12 operates, allowing the fumes to pass sequentially through the first smoke inlet 212, the smoke collection chamber 211, and the air duct 353 before reaching the air inlet of the fan assembly 12 and being discharged outwards. This ensures that the range hood 1 can still maintain normal operation even with the connector 30 designed in this way.

[0023] The following combination Figures 1-10 The specific structure of the range hood 1 will be described in detail. The range hood 1 includes the main body 10, the smoke collection chamber assembly 20, and the connecting parts 30.

[0024] like Figures 1-2As shown, the main body 10 of the range hood is used to generate suction to exhaust the oil fumes produced by the user while cooking to the outside.

[0025] The main body of the range hood 10 includes the main housing 11 and the fan assembly 12.

[0026] The main housing 11 of the range hood serves as the outer shell of the main body 10 of the range hood. The specific shape and material of the main housing 11 of the range hood are not limited here. Designers can make reasonable designs on the shape and material of the main housing 11 of the range hood according to different models of range hoods 1.

[0027] The fan assembly 12 acts to generate suction force for drawing out cooking fumes. The fan assembly 12 may include a fan; the model of the fan is not limited here, and designers can choose the appropriate fan model based on different models of range hoods 1. The fan assembly 12 may also include a silencer, which is used to reduce the noise generated by the fan during operation. Of course, the fan assembly 12 may also include other components, such as sheet metal parts for connecting the fan to the connector 30 (described below). These sheet metal parts are only used to connect the fan to the connector 30, and the specific structure of the sheet metal parts is not limited here.

[0028] The main housing 11 of the range hood has a receiving cavity 111, which can be at least the area within the main housing 11 of the range hood used to accommodate the fan assembly 12.

[0029] The fan assembly 12 is disposed within the receiving cavity 111 of the main housing 11 of the range hood. The fan assembly 12 and the main housing 11 may or may not be connected. For example, when the fan assembly 12 is connected to the main housing 11, the fan assembly 12 can be connected to the main housing 11 by screws. In this case, the main housing 11 can serve as both a decorative outer shell for protecting the fan assembly 12 and a support for it. When the fan assembly 12 is not connected to the main housing 11, the fan assembly 12 is spaced apart from the main housing 11 circumferentially. In this case, the main housing 11 can serve only as a decorative outer shell for protecting the fan assembly 12, while the fan assembly 12 can be supported on the connector 30.

[0030] The smoke collection chamber assembly 20 provides a channel for the flow of cooking fumes. The fumes generated by the user while cooking are drawn into the smoke collection chamber assembly 20 by the suction force generated by the range hood body 10, and then discharged outdoors by the range hood body 10. The specific structure of the smoke collection chamber assembly 20 will be described in detail below. It is understood that the specific structure of the smoke collection chamber assembly 20 may vary between different models of range hoods 1.

[0031] The smoke collection chamber assembly 20 is spaced apart from the main body 10 of the range hood, meaning that the smoke collection chamber assembly 20 does not contact the main body 10 of the range hood in spatial dimension.

[0032] The smoke collection chamber assembly 20 includes a smoke collection chamber housing 21.

[0033] The smoke collection chamber housing 21 serves as the outer shell of the smoke collection chamber assembly 20. The specific shape and material of the smoke collection chamber housing 21 are not limited here. Designers can make reasonable designs on the shape and material of the smoke collection chamber housing 21 according to different models of range hoods 1.

[0034] The smoke collection chamber shell 21 has a smoke collection chamber 211 and a first smoke inlet 212 communicating with the smoke collection chamber 211. The smoke collection chamber 211 should be understood as the area inside the smoke collection chamber shell 21 used for collecting and supplying oil fumes, and the first smoke inlet 212 should be understood as the opening on the smoke collection chamber shell 21 used for supplying oil fumes into the smoke collection chamber 211.

[0035] The connector 30 serves as an intermediate connection structure between the main body 10 of the range hood and the smoke collection chamber assembly 20. In other words, the main body 10 of the range hood is connected to the smoke collection chamber assembly 20 through the connector 30. The specific structure of the connector 30 will be described in detail below.

[0036] The connector 30 can be detachably connected to both the main body 10 of the range hood and the smoke collection chamber assembly 20. For example, the connector 30 can be screwed or snapped together with the main body 10 of the range hood and with the smoke collection chamber assembly 20.

[0037] The connector 30 forms an air duct 353 that connects the smoke collection chamber 211 and the air inlet of the fan assembly 12. The air duct 353 can be understood as a channel in the connector 30 for the circulation of oil fumes. When the user cooks, the oil fumes are drawn into the smoke collection chamber 211 from the first smoke inlet 212 under the suction force generated by the fan assembly 12. The fumes then flow from the smoke collection chamber 211 to the air duct 353, then from the air duct 353 to the air inlet of the fan assembly 12, and finally out to the outside from the exhaust outlet of the fan assembly 12.

[0038] Based on the range hood 1 in this application embodiment, a connector 30 is provided, and the connector 30 is detachably connected to the range hood body 10 and the smoke collection chamber assembly 20, which facilitates the user to replace and clean the range hood body 10 or the smoke collection chamber assembly 20 in the future. At the same time, the connector 30 also forms an air duct 353 for the circulation of oil fumes. The air duct 353 is connected to the air inlet of the smoke collection chamber 211 and the fan assembly 12, which facilitates the oil fumes to enter the air inlet of the fan assembly 12 from the smoke collection chamber 211 through the air duct 353, and then be discharged to the outside.

[0039] like Figures 2-4As shown, considering that the connector 30 is used to connect the main body 10 of the smoke hood and the smoke collection chamber assembly 20, the connector 30 can have many specific forms. In order to simplify the specific structure of the connector 30, it is designed that in some embodiments, the connector 30 has a first end face 35 close to the smoke collection chamber assembly 20. The first end face 35 is provided with a receiving groove 351 recessed in the direction away from the smoke collection chamber assembly 20. The smoke collection chamber assembly 20 also includes a first cover plate 22. The first cover plate 22 is provided corresponding to the first smoke inlet 212. The first cover plate 22 has a first position of closing the first smoke inlet 212 and a second position of opening the first smoke inlet 212. The first cover plate 22 can be flipped relative to the hole axis of the first smoke inlet 212 to realize the switching between the first position and the second position. In the second position, at least a part of the first cover plate 22 is received in the receiving groove 351.

[0040] The first end face 35 of the connector 30 can be either a plane or a curved surface. The different specific forms of the connector 30 determine the different ways in which the receiving groove 351 is formed. For example, when the connector 30 is composed of multiple plates, the receiving groove 351 can be formed by bending one of the plates or by surrounding several of the plates.

[0041] The first cover plate 22 is used to open and close the first smoke inlet 212. The specific material of the first cover plate 22 is not limited. Designers can make reasonable choices about the material of the first cover plate 22 according to actual needs. For example, in order to facilitate the user to clean the stains adhering to the first cover plate 22 later, the first cover plate 22 can be made of glass material, but is not limited to it.

[0042] The first cover plate 22 is disposed corresponding to the first smoke inlet 212. The first cover plate 22 can be hinged to the smoke collection chamber housing 21 to align with the first smoke inlet 212. The specific hinge method between the first cover plate 22 and the smoke collection chamber housing 21 is not limited; designers can design it reasonably according to the actual space size of the smoke collection chamber 211. For example, the first cover plate 22 can be connected to the smoke collection chamber housing 21 via a pivot shaft; alternatively, the first cover plate 22 can also be connected to the smoke collection chamber housing 21 via a linkage mechanism. The specific form of this "linkage mechanism" is not limited; for example, some existing simple four-bar or six-bar linkage mechanisms can be directly used.

[0043] The first cover plate 22 can rotate from a first position away from the first smoke inlet 212 relative to the hole axis of the first smoke inlet 212 to a second position. The first cover plate 22 can also rotate from the second position towards the first smoke inlet 212 relative to the hole axis of the first smoke inlet 212 back to the first position. In other words, the first cover plate 22 can be flipped relative to the end face where the opening of the first smoke inlet 212 is located. Here, "first position" can be understood as the position where the first cover plate 22 is rotated to completely close the first smoke inlet 212. For example, the first position can be the position where the inner surface of the first cover plate 22 is parallel to the end face where the opening of the first smoke inlet 212 is located. "Second position" can be understood as the position where the first cover plate 22 is rotated to completely open the first smoke inlet 212. For example, the second position can be the position after the first cover plate 22 has rotated 75 degrees away from the end face of the first smoke inlet 212.

[0044] The first cover plate 22 can be switched from the first position to the second position or from the second position to the first position. This can be achieved by the user applying external force to the first cover plate 22, or by using other components (such as a motor) to apply external force to the first cover plate 22.

[0045] When the first cover plate 22 is in the second position, at least a portion of the first cover plate 22 is accommodated in the receiving groove 351. By designing the receiving groove 351, on the one hand, the first cover plate 22 can be accommodated so that the first cover plate 22 will not interfere with the user's operation; on the other hand, it can save the material of the connecting piece 30; and on the other hand, it can avoid the first cover plate 22 and enhance the flexibility of the first cover plate 22's movement.

[0046] like Figures 3-4 As shown, considering the non-directional nature of the movement trajectory of the fumes, when the first cover plate 22 is in the second position, the fumes will drift towards the inner side of the first cover plate 22. Over time, the fumes will adhere to the inner side of the first cover plate 22, forming oil stains. To facilitate the user's later cleaning of the oil stains adhering to the inner side of the first cover plate 22, in some embodiments, the connector 30 is designed to have a first side 32 for use near the wall, a second side 31 opposite to the first side 32, a third side 33 connecting the second side 31 and the first side 32, and a fourth side 34 connecting the second side 31 and the first side 32 and opposite to the third side 33. The receiving groove 351 passes through the third side 33 and the fourth side 34. In this design, by designing a receiving groove 351 that penetrates the third side 33 and the fourth side 34 of the connector 30, on the one hand, the connector 30 can reduce the obstruction of the first cover plate 22 when the first cover plate 22 is in the second position, which is beneficial for the user to clean the stains adhering to the inner side of the first cover plate 22 later. On the other hand, it can further save the material of the connector 30.

[0047] like Figure 2 As shown, considering the different specific forms of the smoke collection chamber assembly 20 in different models of range hoods 1, in order to reserve sufficient space for user operation on the cooktop surface M, in some embodiments, the main housing 11 of the range hood has a first surface 115 for use near the wall and a second surface 116 opposite to the first surface 115. The smoke collection chamber housing 21 is located near the first surface 115 of the main housing 11 of the range hood, the connector 30 has a first side surface 32 for use near the wall, and the port of the duct 353 connecting to the smoke collection chamber 211 is located near the first side surface 32. That is to say, the smoke collection chamber housing 21 has a thin-shell structure; in other words, the thickness of the smoke collection chamber housing 21 in the direction perpendicular to the wall is small. In this design, by designing the smoke collection chamber housing 21 as a thin-shell structure and designing the smoke inlet of the duct 353 on the side near the first side surface 32 of the connector 30, the smoke collection chamber assembly 20 can be set close to the wall as a whole, so as to reserve sufficient space for user operation on the cooktop surface M.

[0048] Specifically, the main housing 11 of the range hood includes a first side panel 112 that is away from the wall when in use, a second side panel 113 connected to the left side of the first side panel 112, and a third side panel 114 connected to the right side of the second side panel 113. Here, the surface of the first side panel 112 facing away from the wall is the aforementioned second surface 116, and the surface of the second side panel 113 away from the first side panel 112, or the surface of the third side panel 114 away from the first side panel 112, is the aforementioned first surface 115.

[0049] Considering that some components of the range hood 1 (such as the fan assembly 12) require electrical control, to improve the intelligence and portability of the range hood 1, in some embodiments, the connector 30 is designed to have a second side 31 facing away from the wall when in use. The range hood 1 also includes a control panel 40, which is connected to the second side 31 of the connector 30. In this design, by designing the control panel 40, the user can realize the smoke removal, lighting, and other functions of the range hood 1 by operating the control panel 40.

[0050] The control panel 40 is used, but is not limited to, to realize the functions of smoke removal and lighting of the range hood 1. The control panel 40 can be a button-type operation panel or a touch screen operation panel. The control panel 40 has a variety of function buttons, and the user can put the range hood 1 into different working states by touching different function buttons. For example, by touching the smoke removal function button, the range hood 1 is put into the smoke removal working state.

[0051] The second side 31 of the connector 30 can be understood as the surface of the connector 30 facing the user when in use. The second side 31 can be a plane or a curved surface.

[0052] The second side 31 of the connector 30 may be provided with a fourth groove 311. The control panel 40 is located in the fourth groove 311 and connected to the connector 30. The control panel 40 and the connector 30 may be detachably connected. To facilitate the user's later maintenance of the wiring of the control panel 40, for example, the control panel 40 may be connected to the connector 30 by a screw-locking structure.

[0053] like Figures 5-6 As shown, considering the after-sales installation issues of the range hood 1, for example, when the range hood 1 is installed in the kitchen, the main body 10 of the range hood is usually embedded in the kitchen cabinet to ensure the overall aesthetics of the kitchen, while the control panel 40 is generally exposed outside the kitchen cabinet for user operation. In order to ensure the aesthetics between the control panel 40 and the cabinet after the main body 10 of the range hood is embedded in the cabinet, it is designed that, in some embodiments, the control panel 40 has an exterior surface 41 facing away from the wall, and the main housing 11 of the range hood has a second surface 116 facing away from the wall. The second surface 116 and the exterior surface 41 are spaced apart to form an accommodating space 117. The accommodating space 117 is used to accommodate the cabinet when in use, so that the exterior surface 41 of the control panel 40 is flush with the outer surface of the cabinet when in use. In this design, the outer surface of the cabinet can be understood as the surface of the cabinet facing away from the wall, such as the surface of the cabinet door. The accommodating space 117 formed between the outer surface 41 of the control panel 40 and the second surface 116 of the main housing 11 of the range hood can be used to accommodate the cabinet door, so that the outer surface 41 of the control panel 40 and the outer surface of the cabinet are in the same plane. In this design, by designing the outer surface 41 of the control panel 40 and the second surface 116 of the main housing 11 of the range hood to form an accommodating space 117, the accommodating space 117 is used to accommodate the cabinet, so that the outer surface 41 is in the same plane as the outer surface of the cabinet when in use. This can enhance the structural compactness between the range hood 1 and the cabinet, and at the same time improve the aesthetics of the range hood 1 installed in the kitchen.

[0054] like Figures 3-4As shown, considering that the connector 30 serves as the intermediate connection structure between the range hood body 10 and the smoke collection chamber assembly 20, the weight of the range hood body 10 and the smoke collection chamber assembly 20 will be borne by the connector 30. To ensure that the connector 30 can better support the range hood body 10 and the smoke collection chamber assembly 20, the connector 30 can be made of a material with good rigidity and hardness. For example, the connector 30 can be a sheet metal part. Of course, to enhance the support strength of the connector 30 for the range hood body 10 and the smoke collection chamber assembly 20, in some embodiments, the range hood 1 also includes a reinforcing member 50. The reinforcing member 50 is disposed in the air duct 353 of the connector 30, and the reinforcing member 50 is detachably connected to the connector 30, and / or the reinforcing member 50 is detachably connected to the range hood body 10 and / or the smoke collection chamber assembly 20. In other words, the reinforcing member 50 is equivalent to a reinforcing rib set within the air duct 353 of the connecting member 30. The reinforcing member 50 assists the connecting member 30 in supporting the weight of the range hood body 10 and the smoke collection chamber assembly 20, thereby ensuring the stability of the connections between the range hood body 10 and the connecting member 30, the range hood body 10 and the reinforcing member 50, the smoke collection chamber assembly 20 and the connecting member 30, and the smoke collection chamber assembly 20 and the reinforcing member 50. The specific structure of the reinforcing member 50 will be described in detail below. The reinforcing member 50 can be non-detachably connected to the connecting member 30; for example, the reinforcing member 50 can be integrally molded onto the connecting member 30 using injection molding. Alternatively, the reinforcing member 50 can be detachably connected to the connecting member 30; for example, the reinforcing member 50 can be connected to the connecting member 30 using a screw-locking structure. The reinforcing member 50 can be non-detachably connected to the range hood body 10, for example, by welding. Alternatively, the reinforcing member 50 can be detachably connected to the range hood body 10, for example, by using a screw-locking structure. The reinforcing member 50 can also be non-detachably connected to the smoke collection chamber assembly 20, for example, by welding. Alternatively, the reinforcing member 50 can be detachably connected to the smoke collection chamber assembly 20, for example, by using a screw-locking structure.

[0055] It is understandable that the reinforcing member 50 is used as a reinforcing rib to strengthen the structural strength of the connecting member 30. Considering that the reinforcing member 50 is set in the air duct 353 of the connecting member 30, the oil fumes will inevitably adhere to the reinforcing member 50 and form oil stains during the flow of oil fumes in the air duct 353. In order to enable the oil stains adhering to the reinforcing member 50 to automatically detach from the reinforcing member 50 under the action of gravity, it is designed that, in some embodiments, the reinforcing member 50 includes a guide plate 51 and a connecting plate 52. The guide plate 51 is set in the air duct 353 of the connecting member. The guide plate 51 has a guide surface 511 facing away from the stove surface M. The guide surface 511 gradually decreases in distance from the side away from the wall to the side close to the wall. The connecting plate 52 is connected to the guide plate 51, and the connecting plate 52 is detachably connected to at least one of the connecting member 30, the range hood body 10, and the smoke collection chamber assembly 20. In this design, a guide plate 51 is designed to strengthen the structural strength of the connector 30. A guide surface 511 is designed on the guide plate 51 so that oil stains adhering to the guide plate 51 can automatically detach from the guide plate 51 under the action of gravity. A connecting plate 52 is designed to connect with the connector 30, the fan assembly 12 and the smoke collection chamber shell 21 to enhance the connection stability between the reinforcing member 50 and the connector 30.

[0056] The guide plate 51 serves two purposes: firstly, it strengthens the structural strength of the connector 30, and secondly, it drains oil stains adhering to the guide plate 51. The specific shape of the guide plate 51 is not limited. The guide surface 511 of the guide plate 51 is inclined downward from the end away from the wall to the end close to the wall (i.e., towards the stove surface M). When the weight reaches a certain level, the oil stains adhering to the guide surface 511 can overcome the friction between them and the guide surface 511 and flow along the guide surface 511 until they detach from the guide plate 51.

[0057] The connecting plate 52 is used to connect with the connector 30, the main body of the smoke machine 10, and the smoke collection chamber assembly 20. There is no limitation on the number and shape of the connecting plate 52. For example, there can be two connecting plates 52, which are located on the left and right sides of the guide plate 51, respectively.

[0058] The connecting plate 52 is connected to the guide plate 51. The connecting plate 52 and the guide plate 51 can be an integral structure or a separate structure. When the connecting plate 52 and the guide plate 51 are an integral structure, they can be connected by welding. When the connecting plate 52 and the guide plate 51 are separate structures, they can be connected by screws.

[0059] The connecting plate 52 can be detachably connected to at least one of the connecting piece 30, the main body 10 of the range hood, and the smoke collection chamber assembly 20 via a screw-locking structure.

[0060] Specifically, the connector 30 has a first end face 35 near the smoke collection chamber assembly 20, a second end face 36 near the main body 10 of the smoke hood, and a first side face 32 connected between the first end face 35 and the second end face 36 and close to the wall during use. The first end face 35 is provided with a first groove 352, and the second end face 36 is provided with a second groove 361. The first groove 352 is located near the first side face 32 and communicates with a portion of the bottom wall of the second groove 361. The air duct 353 includes the first groove 352 and the second groove 361. The guide plate 51 is inclinedly disposed in the second groove 361 relative to the bottom wall of the second groove 361, and the connecting plate 52 is disposed in the second groove 361 relative to the side wall of the second groove 361, with a portion of the connecting plate 52 extending into the first groove 352.

[0061] like Figures 3-4 As shown, considering that the oil stains adhering to the guide plate 51 flow along the guide surface 511 under the action of gravity, in order to reduce the possibility of oil stains adhering to the end of the guide plate 51, it is designed that, in some embodiments, the air duct 353 has a first port communicating with the smoke collection chamber 211, and the end of the guide plate 51 near the first port is bent toward the smoke collection chamber assembly 20. By designing the end of the guide plate 51 near the first port of the air duct 353 to be bent toward the smoke collection chamber assembly 20, the oil stains adhering to the end of the guide plate 51 can be completely detached from the guide plate 51 under the action of gravity, thereby accelerating the speed at which the oil stains detach from the end of the guide plate 51 and reducing the possibility of oil stains adhering to the end of the guide plate 51.

[0062] like Figure 7 As shown, considering that the smoke collection chamber 211 of the smoke collection chamber housing 21 is used to provide a channel for the flow of cooking fumes, and the first smoke inlet 212 of the smoke collection chamber housing 21 is used as an inlet for the cooking fumes generated by the user to enter the smoke collection chamber 211, the number of smoke inlets of the smoke collection chamber housing 21 determines the efficiency of the cooking fumes entering the smoke collection chamber 211. For example, the more smoke inlets there are, the higher the efficiency of the cooking fumes entering the smoke collection chamber 211 through the smoke inlets. Therefore, in some embodiments, the smoke collection chamber housing 21 also has a second smoke inlet 213 communicating with the smoke collection chamber 211. The smoke collection chamber assembly 20 also includes a second cover plate 23, which is disposed corresponding to the second smoke inlet 213. The second cover plate 23 has a third position for opening the second smoke inlet 213 and a fourth position for closing the second smoke inlet 213. The second cover plate 23 can slide relative to the end face of the second smoke inlet 213 to switch between the third position and the fourth position.

[0063] The second cover plate 23 is used to open and close the second smoke inlet 213. The specific material of the second cover plate 23 is not limited. Designers can make reasonable choices about the material of the second cover plate 23 according to actual needs. For example, in order to facilitate users to clean the stains adhering to the second cover plate 23 later, the second cover plate 23 can be made of glass, but is not limited to glass.

[0064] The second cover plate 23 is disposed corresponding to the second smoke inlet 213. The second cover plate 23 can be connected to the smoke collection chamber housing 21 to align with the second smoke inlet 213. The specific connection method between the second cover plate 23 and the smoke collection chamber housing 21 is not limited; designers can design it reasonably according to the actual space size of the smoke collection chamber 211. For example, the second cover plate 23 can be slidably connected to the smoke collection chamber housing 21 via a slide rail. Alternatively, the second cover plate 23 can be connected to the smoke collection chamber housing 21 via another linkage mechanism. The specific form of this "other linkage mechanism" is not limited; existing simple four-bar or six-bar linkage mechanisms can be directly used. It should be noted that the way the second cover plate 23 opens and closes the second smoke inlet 213 can be the same as or different from the way the first cover plate 22 opens and closes the first smoke inlet 212. When the second cover plate 23 opens and closes the second smoke inlet 213 in the same way as the first cover plate 22 opens and closes the first smoke inlet 212, both the first cover plate 22 and the second cover plate 23 can be slidably connected to the smoke collection chamber housing 21 via a slide rail. The first cover plate 22 and the second cover plate 23 open the first smoke inlet 212 and the second smoke inlet 213 by moving in opposite directions, and close the first smoke inlet 212 and the second smoke inlet 213 by moving in opposite directions. Thus, both the first cover plate 22 and the second cover plate 23 can have a telescopic folding structure. When the way the second cover plate 23 opens and closes the second smoke inlet 213 is different from the way the first cover plate 22 opens and closes the first smoke inlet 212, the first cover plate 22 can be hinged to the smoke collection chamber housing 21 through a certain linkage mechanism, and the second cover plate 23 can be slidably connected to the smoke collection chamber housing 21 through a slide rail. The first cover plate 22 opens and closes the first smoke inlet 212 by rotating, and the second cover plate 23 opens and closes the second smoke inlet 213 by sliding. Here, both the first cover plate 22 and the second cover plate 23 can be made of glass panels.

[0065] The second cover plate 23 can slide from the third position relative to the end face of the second smoke inlet 213 in a direction parallel to the end face of the second smoke inlet 213 to the fourth position. The second cover plate 23 can also slide from the fourth position relative to the end face of the second smoke inlet 213 in a direction parallel to the end face of the second smoke inlet 213 to the third position. Here, the "third position" can be understood as the position where the second cover plate 23 slides to fully open the second smoke inlet 213. For example, the third position can be the position where the second cover plate 23 slides away from the stove surface M and is close to the top of the smoke collection chamber housing 21. The "fourth position" can be understood as the position where the second cover plate 23 slides to fully close the second smoke inlet 213. For example, the fourth position can be the position where the second cover plate 23 slides towards the stove surface M and abuts against the bottom of the smoke collection chamber housing 21.

[0066] The second cover plate 23 can be switched from the third position to the fourth position or from the fourth position to the third position. This can be achieved by the user applying external force to the second cover plate 23, or by applying external force to the second cover plate 23 with the help of other components (such as another motor).

[0067] like Figure 1 and Figure 7 As shown, considering that the range hood 1 has a lighting function, in some embodiments, the smoke collection chamber assembly 20 further includes at least two light sources 24. These at least two light sources 24 are located within the smoke collection chamber 211 and connected to the smoke collection chamber housing 21. The at least two light sources 24 are symmetrically arranged about a plane of symmetry N, which is a plane of the smoke collection chamber housing 21 that is perpendicular to both the wall and the stove surface M when in use. The light sources 24 can be, but are not limited to, incandescent bulbs. The connection between the light sources 24 and the smoke collection chamber housing 21 can be detachable; for example, the light sources 24 can be connected to the smoke collection chamber housing 21 via a screw mechanism. In this design, by placing multiple light sources 24 within the smoke collection chamber 211 of the smoke collection chamber housing 21, the projection of light from the light sources 24 is facilitated. By designing the multiple light sources 24 to be symmetrically arranged about the plane of symmetry N of the smoke collection chamber housing 21, the light projected by the multiple light sources 24 can be evenly distributed.

[0068] like Figure 8 and Figure 9As shown, considering the non-directional movement trajectory of cooking fumes, the fumes will drift towards the first cover plate 22 and / or the second cover plate 23, adhering to their surfaces and forming oil stains. Over time, these oil stains accumulate and drip onto the stove surface M under their own weight. To prevent oil stains from dripping and contaminating the stove surface M, in some embodiments, the range hood 1 is designed to include an oil cup assembly 60. The oil cup assembly 60 is located on the side of the smoke collection chamber assembly 20 away from the connector 30, and it forms an oil storage chamber communicating with the smoke collection chamber 211. The connection between the oil cup assembly 60 and the smoke collection chamber housing 21 can be detachable or non-detachable. When the connection between the oil cup assembly 60 and the smoke collection chamber housing 21 is detachable, the oil cup assembly 60 can be connected to the smoke collection chamber housing 21 via a screw mechanism. The oil cup assembly 60 can then be disassembled by removing the screws, allowing the oil stains accumulated in the oil cup assembly 60 to be cleaned. When the oil cup assembly 60 is non-detachably connected to the smoke collection chamber housing 21, the oil cup assembly 60 can be connected to the smoke collection chamber housing 21 by gluing or welding. In this case, an openable drain port can be provided on the oil cup assembly 60, allowing the oil stains accumulated inside the oil cup assembly 60 to be cleaned by opening the drain port. The oil storage chamber can be the area in the oil cup assembly used to hold oil stains. It should be noted that by designing the oil cup assembly 60 on the side of the smoke collection chamber assembly 20 away from the connector 30, the oil storage chamber of the oil cup assembly 60 can also be used to receive washing water when the user washes the first cover plate 22 and / or the second cover plate 23.

[0069] like Figure 9 As shown, considering that the oil cup assembly 60 can be used to receive washing water from washing the first cover plate 22 and / or the second cover plate 23, in order to allow as much washing water as possible to fall into the oil cup assembly 60, it is designed that, in some embodiments, the oil cup assembly 60 includes an oil cup body 61 and a flange 62. The oil cup body 61 is connected to the side of the smoke collection chamber assembly 20 away from the connector 30, and the oil cup body 61 forms an oil storage chamber. The flange 62 is located on the side of the oil cup body 61 away from the wall and the side away from the stove surface M when in use, and the flange 62 is connected to the oil cup body 61. The flange 62 can be integrally molded onto the oil cup body 61 by injection molding. The flange 62 has a third surface 621 for approaching the wall when in use. The distance between the third surface 621 and the stove surface M gradually decreases from the side away from the wall to the side approaching the wall. By designing a third surface 621 inclined toward the stove surface M on the side of the flange 62 near the wall, the third surface 621 has a guiding function, and the washing water falling on the third surface 621 can slide down into the oil cup body 61 through the third surface 621.

[0070] like Figure 10As shown, considering that the flange 62 not only guides the washing water, but its appearance also determines the overall aesthetics of the oil cup assembly 60, in some embodiments, the smoke collection chamber housing 21 is designed to have a second smoke inlet 213 communicating with the smoke collection chamber 211. The first smoke inlet 212 and the second smoke inlet 213 are both located on the side of the smoke collection chamber housing 21 away from the wall when in use, and the second smoke inlet 213 is located on the side of the smoke collection chamber housing 21 close to the stove surface M when in use. The smoke collection chamber assembly 20 also includes a second cover plate 23 that can close the second smoke inlet 213. The second cover plate 23 has a fourth surface 231 away from the wall when in use. The fourth surface 231 has a first edge line close to the stove surface M. The flange 62 has a fifth surface 622 away from the wall. The fifth surface 622 has a second edge line 6221 away from the stove surface M. When the second cover plate 23 closes the second smoke inlet 213, the second edge line 6221 is further away from the wall than the first edge line, and along the direction perpendicular to the wall, the distance between the second edge line 6221 and the first edge line (e.g.) Figure 10 H1 as shown is greater than or equal to 3 mm and less than or equal to 5 mm; and / or, when the second cover 23 closes the second smoke inlet 213, the second edge line 6221 is further away from the stove surface M than the first edge line, and along the direction perpendicular to the stove surface M, the distance between the second edge line 6221 and the first edge line (as shown) Figure 10 The value of H2 shown is greater than or equal to 3 mm and less than or equal to 5 mm. For example, the value of H1 can be, but is not limited to, 3 mm, 4 mm, or 5 mm, and the value of H2 can be, but is not limited to, 3 mm, 4 mm, or 5 mm. In this design, by reasonably designing the dimension of the second edge line 6221 of the flange 62 relative to the first edge line of the fourth surface 231 in the direction perpendicular to the wall / stove plane M, it is possible to ensure both good water flow guidance and the overall aesthetics of the oil cup assembly 60.

[0071] like Figure 8 As shown, considering that when oil fumes flow through the smoke collection chamber 211, they will adhere to the smoke collection chamber housing 21, forming oil stains. Over time, these oil stains will drip down under their own weight. To ensure that the oil stains formed in the smoke collection chamber housing 21 can also flow into the oil cup assembly 60 for collection, in some embodiments, the smoke collection chamber housing 21 is designed with a guide surface 214 positioned close to the wall during use. The distance between the guide surface 214 and the stove surface M gradually decreases from the side closest to the wall to the side furthest from the wall. It should be noted that the side of the guide surface 214 closest to the stove surface M is located above the oil cup assembly 60, so that the oil stains can drip directly into the oil cup assembly 60 along the guide surface 214.
