Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a mounting assembly and a range hood. Background Art

[0002] Range hoods have become an indispensable kitchen appliance in people's daily lives. They can quickly remove fumes generated during cooking, reducing pollution, purifying the air, and significantly improving people's quality of life.

[0003] Most existing range hoods are mounted in a hanging style. Typically, a hook groove is provided on the hood back panel, and a latch is provided at the hood mounting location. The hook groove and latch cooperate to achieve hanging installation of the range hood. However, since a wall cabinet is usually installed above the range hood, conventional latches with an upwardly tilted portion require the range hood to be first raised to a certain height to allow the hook to enter the hook groove, and then lowered to complete the engagement of the hook and the hook groove. This installation method results in a gap between the range hood and the wall cabinet above after installation. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a mounting assembly is provided. The mounting assembly includes a limit member, a limit fitting member, and an elastic member, wherein the limit member is applied to a mounting surface, the limit fitting member is configured to be movable along a predetermined direction at least between an initial position and an installed position, and one of the limit member and the limit fitting member is connected to the elastic member, wherein when the limit fitting member is in the initial position, the elastic member is in an initial state; during the process of the limit fitting member moving from the initial position to the installed position, the elastic member is in a first deformed state; and when the limit fitting member is in the installed position, the elastic member is in a second deformed state or returns to the initial state, and the limit member and the limit fitting member are engaged.

[0005] The installation assembly provided by the present invention has a limiter for use on the installation surface. After the limiter fitting is moved from an initial position to an installation position along a predetermined direction, the limiter fitting located at the installation position engages with the limiter to complete the installation. The predetermined direction can be vertical, opposite to the direction of gravity. By moving the limiter fitting along such a predetermined direction to achieve installation, the space above the installation assembly can be avoided. When the installation assembly is used for a range hood, there is no need to reserve space above the range hood for installation, thereby achieving seamless installation of the range hood and the wall cabinet above. Moreover, the structure of such an installation assembly is very simple, and production and processing are simpler, more convenient, and easy to implement.

[0006] For example, a mating structure is provided between the stopper and the mating member, the mating structure comprising a concave portion and a convex portion. When the mating member is in the installed position, the convex portion engages the concave portion. This arrangement allows the stopper and mating member to engage with each other, resulting in a simpler and easier-to-implement overall structure.

[0007] For example, the limiting concave portion is provided on the limiting member, and the limiting convex portion is provided on the limiting mating member; or, the limiting concave portion is provided on the limiting mating member, and the limiting convex portion is provided on the limiting member. When the limiting member and the limiting mating member are engaged, the limiting concave portion provided on the limiting member can provide support for the limiting convex portion on the limiting mating member, thereby making the engagement of the limiting member and the limiting mating member more stable. Installation using such an installation assembly can also be more stable. When used in a range hood, the range hood can be more stably mounted on the mounting surface.

[0008] For example, a guide slope is provided on one side of the position-limiting member, and the guide slope is connected to the position-limiting recess. When the position-limiting fitting member moves from the initial position to the installation position, the guide slope guides the position-limiting protrusion to engage with the position-limiting recess. When the position-limiting fitting member moves from the initial position to the installation position, the position-limiting protrusion can abut against the guide slope. Under the guidance of the guide slope, the position-limiting protrusion is more easily engaged with the position-limiting recess, and the position-limiting member and the position-limiting fitting member are more easily engaged. Such an installation assembly can also be more simple and convenient to install.

[0009] For example, the projections of the limiting concave portion and the limiting convex portion on the mounting surface both have arc-shaped contour lines, which makes it easier for the limiting convex portion to fit into the limiting concave portion, and the mounting assembly can be installed more simply and conveniently.

[0010] For example, one of the position-limiting member and the position-limiting mating member connected to the elastic member is configured as a rotating member rotatable about a rotation center. The rotating member has a rotating end and a connecting end, with the connecting end being closer to the rotation center than the rotating end. One end of the elastic member is fixedly disposed, and the other end is connected to the rotating end. Because the rotating end can be relatively far from the rotation center and the rotating end is connected to the elastic member, the elastic force exerted by the elastic member on the rotating end can cause the position-limiting member to rotate a smaller amount about the rotation center. This prevents the elastic force generated by the deformation of the elastic member from having an excessive impact on the position-limiting member, thereby making the overall structure more stable and preventing problems such as excessive shaking of the position-limiting member due to deformation of the elastic member.

[0011] According to another aspect of the present invention, a range hood is provided, comprising a range hood back plate and any one of the mounting assemblies described above, wherein a position-limiting fitting is disposed on the range hood back plate.

[0012] For example, the mounting assembly includes an anti-drop hook disposed on the mounting surface. The anti-drop hook includes a connecting portion and a baffle portion. The connecting portion is connected between the mounting surface and the baffle portion. When the limiting fitting is in the installed position, the baffle portion limits the range hood back panel. The anti-drop hook prevents the range hood back panel from tilting and falling away from the mounting surface.

[0013] For example, one end of the baffle portion is connected to the connecting portion in a predetermined direction, and the other end has a raised portion extending away from the mounting surface and away from the connecting portion. During installation of the range hood, the provision of the raised portion can make it easier for the range hood back panel to enter between the baffle portion and the mounting surface, thereby making installation of the range hood simpler and more convenient.

[0014] For example, the installation assembly includes a guide plate disposed on the mounting surface. The guide plate extends perpendicular to the mounting surface and in a predetermined direction. When the retaining member moves in the predetermined direction, the side of the range hood back panel abuts the guide plate. Due to the guide plate, the range hood can be installed without the need to laboriously locate the installation direction. Instead, the side of the range hood back panel abuts the guide plate and then installs in the predetermined direction. For example, after abutting the side of the range hood back panel against the guide plate, the range hood can be pushed upward to complete the installation. The provision of the guide plate can make range hood installation simpler and more convenient.

[0027] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0028] According to one aspect of the present invention, a mounting assembly is provided. The mounting assembly can be applied to various suitable devices, such as range hoods. Therefore, according to another aspect of the present invention, a range hood is provided, which can include a range hood backplate and any of the mounting assemblies described below.

[0029] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4, the installation assembly may include a limit member 100, a limit fitting member 200 and an elastic member 300. The limit member 100 can be used on the installation surface 12. Specifically, the limit member 100 can be installed on the installation surface 12, and the limit fitting member 200 can be constructed to be movable relative to the limit member 100 along a predetermined direction (direction XX in the figure) at least between an initial position and an installation position. When the limit fitting member 200 is in the installation position, the limit member 100 can be engaged with the limit fitting member 200. By engaging the limit member 100 with the limit fitting member 200, the installation of the part to be installed can be completed. When the installation assembly is used for the range hood 11, the limit fitting member 200 can be set on the range hood back plate 600. When the limit member 100 is engaged with the limit fitting member 200, the limit member 100 can limit the limit fitting member 200, and thus limit the range hood back plate 600, thereby completing the installation of the range hood 11. The installation direction of the range hood 11 can be along a predetermined direction XX. For example, for a mounting surface 12 disposed on a vertical surface, the predetermined direction XX can be parallel to the vertical direction, and the range hood 11 can be installed upward along the vertical direction. The position-limiting fitting 200 can be movable along the predetermined direction XX between an initial position and an installation position. The position-limiting fitting 200 can be disposed on the range hood back panel 600 and move with the range hood 11. When the range hood 11 is detached from the mounting surface 12, the position-limiting fitting 200 can be in the initial position. After the range hood 11 is installed, the position-limiting fitting 200 can be in the installation position. It is worth noting that the position-limiting fitting 200 is not necessarily in the initial position only when the range hood 11 is detached from the mounting surface 12. The position-limiting fitting 200 can also be in the initial position when the range hood 11 is about to be installed, when the position-limiting fitting 200 is in contact with the position-limiting fitting 100 without any interaction force between the position-limiting fitting 100 and the position-limiting fitting 100.

[0030] One of the limiting member 100 and the limiting fitting member 200 can be connected to the elastic member 300. When the limiting fitting member 200 is in the initial position, the elastic member 300 can be in the initial state; when the limiting fitting member 200 moves from the initial position to the installation position, the elastic member 300 can be in the first deformed state; when the limiting fitting member 200 is in the installation position, the elastic member 300 can be in the second deformed state or can return to the initial state, and the limiting member 100 can be engaged with the limiting fitting member 200. The limiting member 100 or the limiting fitting member 200 can be connected to the elastic member 300. Figure 5 and Figure 6Taking the limiting member 100 connected to the elastic member 300 as an example, when the limiting fitting member 200 is in the initial position, the limiting member 100 and the limiting fitting member 200 are separated from each other or just in contact without any mutual force. At this time, the elastic member 300 is in the initial state, and it can be considered that the elastic member 300 has no elastic force on the limiting member 100. Install the range hood 11 along the predetermined direction XX, see Figure 3 , Figure 3 The figure shows the process of the limiting fitting 200 moving from the initial position to the installation position. During this process, the limiting fitting 200 presses against the limiting fitting 100. There is an interaction force between the limiting fitting 200 and the limiting fitting 100. Under the action of this interaction force, the elastic member 300 is in a first deformation state. As shown in the figure, the elastic member 300, which can be in the form of a spring, is compressed. Of course, for other forms of elastic members 300, the elastic member 300 can also undergo any other suitable form of deformation. At this time, since the elastic member 300 is in the first deformation state, the elastic member 300 exerts an elastic force on the limiting member 100. Subsequently, after the limiting fitting 200 reaches the installation position, see Figure 4 At this time, the stopper 100 will reset under the elastic force exerted by the elastic member 300 in the first deformed state, so that the stopper 100 can engage with the stopper fitting member 200 to limit the stopper fitting member 200 and thus limit the range hood back plate 600, thereby completing the installation of the range hood 11. Specifically, when the stopper fitting member 200 is in the installation position, depending on the different types of elastic member 300 and the different types of the stopper 100, the elastic member 300 may still be deformed and in the second deformed state. For example, when the stopper 100 and the stopper fitting member 200 are separated from each other, the stopper 100 may be in the first position, and when the stopper 100 and the stopper fitting member 200 are engaged, the stopper 100 may be in the second position. If the first position and the second position are different, the elastic member 300 will still have a certain deformation after the range hood 11 is installed, and the elastic member 300 is in the second deformed state. It is understandable that the deformation of the elastic member 300 in the second deformation state may be smaller than that in the first deformation state. When the position-limiting fitting 200 is in the installation position, the elastic member 300 may also return to the initial state. For example, when the first position and the second position of the position-limiting fitting 100 are the same, the elastic member 300 may return to the initial state after the range hood 11 is installed. Of course, the position-limiting fitting 200 may also be connected to the elastic member 300. Figure 7, taking the limiting fitting 200 connected to the elastic member 300 as an example, the elastic member 300, the limiting fitting 200 and the range hood back panel 600 can move together as a whole. When the limiting fitting 200 is in the initial position, the limiting member 100 and the limiting fitting 200 are separated from each other or just in contact without any mutual force. At this time, the elastic member 300 is in the initial state, and it can be considered that the elastic member 300 has no elastic force on the limiting fitting 200. The range hood 11 is installed along the predetermined direction XX. During the process of the limiting fitting 200 moving from the initial position to the installation position, the limiting member 100 presses against the limiting fitting 200. There is an interaction force between the limiting fitting 200 and the limiting member 100. Under the action of this interaction force, the elastic member 300 is in a first deformation state. Here, the first deformation state of the elastic member 300 can be similar to that when the limiting member 100 is connected to the elastic member 300, and will not be described in detail here. At this time, since the elastic member 300 is in the first deformed state, the elastic member 300 exerts an elastic force on the position-limiting fitting 200. Subsequently, after the position-limiting fitting 200 reaches the installation position, the position-limiting fitting 200 will reset under the elastic force exerted by the elastic member 300 in the first deformed state, so that the position-limiting fitting 200 can engage with the position-limiting fitting 100 to limit the position-limiting fitting 200, thereby limiting the position-limiting fitting 200 and the range hood back panel 600, thereby completing the installation of the range hood 11. Specifically, when the position-limiting fitting 200 is in the installation position, depending on the different forms of the elastic member 300 and the different forms of the position-limiting fitting 200, the elastic member 300 may still be deformed and in the second deformed state, or the elastic member 300 may return to its initial state, similar to the above content, and will not be repeated here.

[0031] The installation assembly provided by the present invention has a limit member 100 used on the installation surface 12. After the limit fitting member 200 moves from the initial position to the installation position relative to the limit member 100 in a predetermined direction, the limit fitting member 200 located at the installation position engages with the limit member 100 to complete the installation. The predetermined direction can be in the vertical direction, opposite to the direction of gravity. By moving the limit fitting member 200 along such a predetermined direction to achieve installation, the space above the installation assembly can be avoided from being occupied. When the installation assembly is used for the range hood 11, there is no need to reserve space above the range hood 11, thereby achieving seamless installation of the range hood 11 and the wall cabinet above. Moreover, the structure of such an installation assembly is very simple, and production and processing are simpler, more convenient, and easy to implement.

[0032] In one embodiment of the present invention, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4, a matching structure may be provided between the limiting member 100 and the limiting fitting member 200. The matching structure may include a limiting recess 110 and a limiting protrusion 210, one of which may be provided on the limiting member 100, and the other on the limiting fitting member 200. When the limiting fitting member 200 is located at the installation position, the limiting protrusion 210 may be snapped into the limiting recess 110, and the locking of the limiting member 100 and the limiting fitting member 200 may be completed at this time. The projections of the limiting recess 110 and the limiting protrusion 210 on the installation surface 12 may have contour lines of any suitable form, and preferably, the limiting recess 110 and the limiting protrusion 210 may match. By realizing the locking of the limiting member 100 and the limiting fitting member 200 in this manner, the overall structure is simpler and easier to implement.

[0033] For example, see Figure 5 and Figure 6 The limiting recess 110 can be provided on the limiting member 100, and the limiting protrusion 210 can be provided on the limiting fitting 200. When the limiting member 100 and the limiting fitting 200 are engaged, the limiting recess 110 provided on the limiting member 100 can provide support for the limiting protrusion 210 on the limiting fitting 200, so that the limiting member 100 and the limiting fitting 200 can be more stable when engaged, and the installation using such an installation assembly can also be more stable. When used for the range hood 11, the range hood 11 can be more stably installed on the installation surface 12. In an embodiment not shown, the limiting recess 110 can be provided on the limiting fitting 200, and the limiting protrusion 210 can be provided on the limiting member 100. Through such an arrangement, the effect of the limiting member 100 and the limiting fitting 200 being engaged can also be achieved.

[0034] For example, see Figure 5 and Figure 6 A guide slope 120 may be provided on one side of the position-limiting member 100. Here, the side may be the side close to the position-limiting fitting 200 along the predetermined direction XX. The guide slope 120 may be connected to the position-limiting recess 110. When the position-limiting fitting 200 moves from the initial position to the installation position, the guide slope 120 may guide the position-limiting protrusion 210 to engage with the position-limiting recess 110. When the position-limiting fitting 200 moves from the initial position to the installation position, the position-limiting protrusion 210 may abut against the guide slope 120. Under the guidance of the guide slope 120, the position-limiting protrusion 210 is more easily engaged with the position-limiting recess 110, and the engagement between the position-limiting member 100 and the position-limiting fitting 200 is also easier. Such an installation assembly can be more simple and convenient to install.

[0035] For example, the projections of the limiting recess 110 and the limiting protrusion 210 on the mounting surface 12 can both have an arcuate contour. During the movement of the limiting fitting 200 from the initial position to the mounting position, the limiting protrusion 210 abuts against the limiting member 100 until the limiting protrusion 210 abuts against the edge of the limiting recess 110, at which point the limiting protrusion 210 can snap into the limiting recess 110. The projections of the limiting recess 110 and the limiting protrusion 210 on the mounting surface 12 both have an arcuate contour. This makes it easier for the limiting protrusion 210 to snap into the limiting recess 110, making installation of the assembly simpler and more convenient.

[0036] For example, one of the limiting member 100 and the limiting fitting 200 connected to the elastic member 300 can be constructed as a rotating member that can rotate around a rotation center. The rotating member can have a connecting end 130 and a rotating end 140. The connecting end 130 is closer to the rotation center than the rotating end 140. One end of the elastic member 300 is fixed and the other end is connected to the rotating end 140. Here, one end of the elastic member 300 can be fixed on the mounting surface 12. The connecting end 130 can be rotatably connected to a fixing pin 150, and the fixing pin 150 can form a rotation center. Taking the limiting member 100 connected to the elastic member 300 as an example, see Figure 5 The position-limiting member 100 may include a connecting end 130 and a rotating end 140. The connecting end 130 may be rotatably connected to a fixing pin 150, which may be disposed on the mounting surface 12. Since the rotating end 140 may be relatively far from the rotation center and is connected to the elastic member 300, the elastic force exerted by the elastic member 300 on the rotating end 140 may cause the position-limiting member 100 to rotate relatively slightly around the rotation center, thereby preventing the elastic force generated by the deformation of the elastic member 300 from having an excessive impact on the position-limiting member 100. This may also make the overall structure more stable, and prevent problems such as excessive shaking of the position-limiting member 100 caused by deformation of the elastic member 300.

[0037] In one embodiment of the present invention, see Figure 1 and Figure 2 The range hood 11 includes a range hood back plate 600 and a mounting assembly according to the above embodiment. The position-limiting fitting 200 can be disposed on the range hood back plate 600. Since the mounting assembly according to the above embodiment has the aforementioned beneficial effects, the range hood 11 including the mounting assembly according to the above embodiment also has the aforementioned beneficial effects, which will not be described in detail here.

[0038] Again, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6The mounting assembly may include an anti-detachment hook 400 disposed on the mounting surface 12. The anti-detachment hook 400 may include a connecting portion 410 and a baffle portion 420. The connecting portion 410 may be connected between the mounting surface 12 and the baffle portion 420. When the position-limiting fitting 200 is located in the mounting position, the baffle portion 420 may limit the range hood back panel 600. The baffle portion 420 may be inclined at a certain angle to the mounting surface 12, or may be parallel to the mounting surface 12. When the position-limiting fitting 200 is located in the mounting position, the baffle portion 420 may limit the range hood back panel 600 in a direction away from the mounting surface 12. The provision of the anti-detachment hook 400 may prevent the range hood back panel 600 from tilting and falling off in a direction away from the mounting surface 12.

[0039] For example, see Figure 5 , the baffle portion 420 can be parallel to the mounting surface 12. When the baffle portion 420 is tilted toward the mounting surface 12, the baffle portion 420 may form an obstruction to the range hood back panel 600 during the installation process of the range hood 11, and when the baffle portion 420 is tilted toward away from the mounting surface 12, the baffle portion 420 has a poor limiting effect on the range hood back panel 600 in the direction away from the mounting surface 12. The baffle portion 420 parallel to the mounting surface 12 can form a better limiting effect on the range hood back panel 600 in the direction away from the mounting surface 12, and such a baffle portion 420 will not form an obstruction to the range hood back panel 600 during the installation process of the range hood 11, so that the installation of such a range hood 11 can be simpler and more convenient, and the range hood back panel 600 can be prevented from tilting and falling off in the direction away from the mounting surface 12.

[0040] For example, see Figure 2 and Figure 5 One end of the baffle portion 420 in the predetermined direction XX may be connected to the connecting portion 410, and the other end may have a raised portion 421 extending away from the mounting surface 12 and away from the connecting portion 410. During installation of the range hood 11, the provision of the raised portion 421 may facilitate insertion of the range hood back panel 600 between the baffle portion 420 and the mounting surface 12, thereby making installation of the range hood 11 simpler and more convenient.

[0041] For example, the installation assembly may include a guide plate 500 disposed on the mounting surface 12. The guide plate 500 may be perpendicular to the mounting surface 12 and extend in a predetermined direction XX. When the position-limiting fitting 200 moves in the predetermined direction XX, the side of the range hood back panel 600 may abut against the guide plate 500. During installation of the range hood 11, the guide plate 500 can guide the installation direction of the range hood 11. Thus, the guide plate 500, extending in the predetermined direction XX, can guide the range hood 11 to a predetermined position along the predetermined direction XX. Due to the provision of the guide plate 500, installation of the range hood 11 can be simplified by eliminating the need to locate the installation direction. Instead, the range hood 11 can be installed by simply abutting the side of the range hood back panel 600 against the guide plate 500 and then pushing the range hood 11 upward. The provision of the guide plate 500 can make installation of the range hood 11 simpler and more convenient.

[0042] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front", "back", "up", "down", "left", "right", "horizontal", "vertical", "vertical", "horizontal", "top", "bottom", etc. are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0043] For ease of description, area-relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the regional positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that area-relative terms include not only the orientation of the components as described in the figures, but also different orientations in use or operation. For example, if the components in the drawings are inverted as a whole, the situation where the components are "above other components or features" or "above other components or features" will include the situation where the components are "below other components or structures" or "below other components or structures". Thus, the exemplary term "above" may include both the orientations "above" and "below". In addition, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document is intended to include all of these situations.

[0044] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.
