Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a filter structure and a range hood. Background Technology

[0002] After a period of use, kitchen range hoods need to have their filters disassembled and cleaned to maintain their filtering performance. However, current range hoods still present many inconveniences in terms of quick filter removal and installation.

[0003] The main reason for this problem is that existing filter plates are usually placed inside the range hood and secured with screws or clips. During operation, the range hood vibrates, and if screws are used, they are prone to loosening under long-term vibration, affecting the stability of the filter. Clips, on the other hand, are typically installed inside the range hood for aesthetic reasons, increasing the difficulty of operation. Utility Model Content

Detailed Implementation

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0030] The first aspect of this utility model provides a filter structure, such as... Figures 1 to 3 As shown, the device includes a frame 1, a filter assembly 2, and an operating component 3. The frame 1 has a mounting cavity 11 with an opening for the filter assembly 2 to enter and exit. The filter assembly 2 is disposed within the mounting cavity 11. The operating component 3 is connected to the frame 1 and has an operating member 31 that movably engages with the frame 1. The operating member 31 extends to the opening of the mounting cavity 11 and has a locking position that prevents the filter assembly 2 from exiting the mounting cavity 11 and an unlocking position that allows the filter assembly 2 to exit the mounting cavity 11.

[0031] When the filter structure provided in the first aspect of this utility model is in use, the operating member 31 can be used to block the outer side (the side facing the user) of the filter assembly 2 when it is in the locked position, preventing the filter assembly 2 from coming out of the opening of the mounting cavity 11; when it is necessary to switch the operating member 31 to the unlocked position, the user can make the operating member 31 move relative to the frame 1 to cancel the blocking of the outer side of the filter assembly 2, at which time the filter assembly 2 can come out of the opening of the mounting cavity 11.

[0032] Therefore, in the filter structure provided in the above embodiment, the filter assembly 2 can be confined within the mounting cavity 11 by the operating member 31, preventing the filter assembly 2 from detaching from the opening of the mounting cavity 11, thus achieving the limiting of the filter assembly 2. Compared with the traditional method of fixing with screws, the above method is less affected by the vibration of the range hood and can effectively maintain the installation stability of the filter assembly 2 for a long time; compared with the traditional method of fixing with a snap-fit ​​structure, when it is necessary to disassemble the filter assembly 2, the user can switch the operating member 31 to the unlocking position from the opening to disassemble the filter assembly 2, making the operation simpler.

[0033] There are multiple ways in which the operating component 31 can be engaged with the frame 1. For example, the operating component 31 can be engaged with the frame 1 in a sliding manner, and the switching between two workstations can be achieved by sliding relative to the frame 1. Or the operating component 31 can be engaged with the frame 1 in a rotating manner, and the switching between two workstations can be achieved by rotating relative to the frame 1, and so on.

[0034] Taking the sliding fit between the operating component 31 and the frame 1 as an example, in optional embodiments, such as Figure 3 As shown, the operating component 3 includes a fixing member 32 and an elastic member 33. The fixing member 32 is fixedly connected to the frame 1, and the elastic member 33 is located between the fixing member 32 and the operating member 31. The elastic member 33 is configured to apply a spring force to the operating member 31 to switch from the unlocking position to the locking position.

[0035] In the above embodiment, the fixing member 32 serves to prevent one end of the elastic member 33 from moving relative to the frame 1. When the operating member 31 is not subjected to external force by the user, under the elastic force of the elastic member 33, the operating member 31 is in the locked position, preventing the filter assembly 2 from coming out of the mounting cavity 11; when the user overcomes the elastic force of the elastic member 33 and applies external force to the operating member 31, the operating member 31 switches from the locked position to the unlocked position, canceling the obstruction of the filter assembly 2, and the user can take out the filter assembly 2 from the mounting cavity 11.

[0036] The fastener 32 can be plate-shaped, block-shaped, or other shapes; any shape that can block one end of the elastic member 33 and be fixed to the frame 1 is acceptable.

[0037] like Figure 3 As shown, the fastener 32 is plate-shaped.

[0038] Among them, the elastic element 33 can be a helical spring, or it can be other structures with a certain degree of elasticity.

[0039] In addition, the operating unit 31 can be configured as one or multiple.

[0040] like Figure 3 As shown, there are two operating components 31, which are distributed on the upper and lower sides of the fixing component 32. Each operating component 31 is provided with an elastic component 33 between itself and the fixing component 32.

[0041] The advantage of the above setup is that, during use, the filter assembly 2 can be released by simultaneously operating both operating parts 31. Compared to using only one operating part 31, this avoids the filter assembly 2 from accidentally detaching from the mounting cavity 11 due to user accidental contact. Furthermore, when switching the two operating parts 31 to the unlocking position, they need to be moved towards each other for easy application of force by the user.

[0042] In alternative implementations, such as Figure 3 As shown, the operating member 31 may include a horizontal plate 311 and a vertical plate 312 connected to the horizontal plate 311. The horizontal plate 311 can be used to abut against the end of the elastic member 33 that is away from the fixing member 32. The vertical plate 312 can prevent the filter assembly 2 from coming out of the mounting cavity 11 when the operating member 31 is in the locked position.

[0043] Specifically, the vertical plate 312 is perpendicularly connected to the horizontal plate 311.

[0044] In alternative implementations, such as Figure 2 and Figure 3 As shown, the operating component 3 also includes a first plate 34 and a second plate 35. One side of the first plate 34 is connected to the side of the fixing member 32 facing the user, and one side of the second plate 35 is connected to the side of the operating member 31 facing the user. The second plate 35 is stacked on top of the first plate 34 in a direction perpendicular to the first plate 34.

[0045] In the above embodiments, the first plate 34 and the second plate 35 can serve to shield the fixing member 32, the elastic member 33 and the operating member 31. Since the second plate 35 is stacked with the first plate 34 in a direction perpendicular to the first plate 34, the second plate 35 can still maintain a good shielding effect during the movement of the first plate 34.

[0046] Specifically, the second plate 35 is located outside the first plate 34 (i.e., the side facing the user), and the first plate 34 is stacked with the second plate 35 at its vertical end. The second plate 35 can slide relative to the first plate 34 in the vertical direction.

[0047] like Figure 3 As shown, when two operating components 31 are configured, two second plates 35 are correspondingly configured, and the two second plates 35 are fixedly connected to the two operating components 31 in a one-to-one correspondence. One of the second plates 35 is stacked with the top of the first plate 34 in the vertical direction, and the other second plate 35 is stacked with the bottom of the first plate 34 in the vertical direction.

[0048] In use, the user can adjust the position of the operating component 31 relative to the frame 1 by moving the second plate 35. For ease of operation, in optional embodiments, such as... Figure 3 As shown, the other side of the second plate 35 has a protrusion 351 for holding, which protrudes in a direction away from the operating member 31.

[0049] When the position of the second plate 35 needs to be adjusted, the user can pull the second plate 35 up or down through the protrusion 351 to facilitate the application of force by the user.

[0050] In an optional implementation, to make the operating element 31 move more stably relative to the frame 1, such as Figure 4 As shown, the frame 1 includes a guide member 12, a fixing member 32 sleeved on the guide member 12 and fixed in position relative to the guide member 12, an elastic member 33 sleeved on the guide member 12, and an operating member 31 sleeved on the guide member 12 and slidingly engaged with the guide member 12 along the extension direction of the guide member 12.

[0051] The guide member 12 not only limits the fixing member 32 along its own radial direction, but also limits the elastic member 33 and guides the operating member 31, ensuring the stability of the operating component 3 during use.

[0052] Specifically, the guide member 12 can be a guide post, and its cross-section can be circular, rectangular, etc.

[0053] In alternative implementations, such as Figure 2 As shown, the frame 1 also includes an outer frame 13 and a box 14 connected to the outer frame 13. A mounting cavity 11 is formed between the outer frame 13 and the box 14. A guide 12 is provided inside the box 14, and a fixing member 32 is fixedly connected inside the box 14. Figure 5 As shown, the end of the box body 14 in the extending direction of the guide member 12 is provided with a through groove 141 for the operation member 31 to enter and exit.

[0054] In the above embodiments, the box body 14 provides installation space for the operating member 31, the fixing member 32 and the elastic member 33. The fixing member 32 can be fixed to the guide member 12 or to the box body 14. Fixing the fixing member 32 to the box body 14 can increase the connection area between the fixing member 32 and the frame 1, thereby ensuring that the position of the fixing member 32 is more secure.

[0055] Since the housing 14 is provided with a through groove 141, when the operating member 31 is in the locked position, the horizontal plate 311 in the operating member 31 is located inside the housing 14, and the vertical plate 312 in the operating member 31 can pass through the through groove 141 to block the filter assembly 2 from coming out of the mounting cavity 11; when the operating member 31 is in the unlocked position, the vertical plate 312 in the operating member 31 can extend into the housing 14 through the through groove 141 to remove the obstruction of the filter assembly 2.

[0056] The aforementioned through groove 141 can further limit the operation member 31 in the locked position, ensuring that the operation member 31 can stably block the filter assembly 2.

[0057] When two operating members 31 are configured, the box body 14 is provided with through slots 141 at both ends of the extension direction of the guide member 12 for the operation members 31 to enter and exit.

[0058] In alternative implementations, such as Figure 2 As shown, the outer frame 13 includes a frame body 131 and a bottom plate 132. The box body 14 is connected to the frame body 131. The bottom plate 132 is located between the frame body 131 and the box body 14. An installation cavity 11 is formed between the bottom plate 132, the frame body 131 and the box body 14. The bottom plate 132 abuts against the side of the filter assembly 2 away from the user.

[0059] The aforementioned base plate 132 is used to abut against the side of the filter assembly 2 away from the user, thereby limiting the filter assembly 2 and, together with the operating component 31, limiting the depth position of the filter assembly 2 within the mounting cavity 11.

[0060] The base plate 132 can be installed in a detachable manner, that is, when the operating component 31 is in the unlocking position, the base plate 132 can also be removed from the opening of the mounting cavity 11.

[0061] In an optional implementation, the filter assembly 2 may include at least one filter, or multiple filters, such as two, three or more.

[0062] like Figure 2 As shown, the filter assembly 2 includes two filters. Correspondingly, the mounting cavity 11 includes a first sub-mounting cavity 111 and a second sub-mounting cavity 112. The first sub-mounting cavity 111 is located on the left side of the frame 1, and the second sub-mounting cavity 112 is located on the right side of the frame 1. The first sub-mounting cavity 111 is used to install one of the filters, and the second sub-mounting cavity 112 is used to install the other filter.

[0063] In an optional embodiment, the housing 14 is connected to the middle of the frame 131 along the arrangement direction of the first sub-mounting cavity 111 and the second sub-mounting cavity 112. The bottom plate 132 is sleeved on the outside of the housing 14 and located inside the frame 131. The first sub-mounting cavity 111 is formed between one side of the housing 14, the bottom plate 132 and the frame 131, and the second sub-mounting cavity 112 is formed between the other side of the housing 14, the bottom plate 132 and the frame 131.

[0064] In the above embodiment, the housing 14 is located between the first sub-mounting cavity 111 and the second sub-mounting cavity 112, which facilitates the operation member 31 in the housing 14 to block the two filters. It should be further noted that the arrangement of the first plate 34 and the second plate 35 can block the opening of the housing 14, preventing the rising fumes from directly contacting the operation member 31, the fixing member 32 and the elastic member 33 inside the housing 14, which is conducive to smoother movement of the operation member 31 and reduces the operating resistance of the user.

[0065] In an optional embodiment, the filter structure further includes a pressure plate 4, which is disposed in the mounting cavity 11 and is located on the side of the filter assembly 2 away from the frame 1. The surface of the pressure plate 4 away from the filter assembly 2 is used to abut against the operating member 31 in the locking position.

[0066] When the operating component 31 is in the locked position, the inner side of the filter assembly 2 abuts against the outer side of the base plate 132, and the outer side of the filter assembly 2 abuts against the inner side of the pressure plate 4, so that the filter assembly 2 is between the pressure plate 4 and the base plate 132. The pressure plate 4 and the base plate 132 clamp the corners of the filter assembly 2 without affecting the filtration effect of the filter assembly 2.

[0067] In addition, by setting the pressure plate 4, the resistance of the operating component 31 can be transmitted to each filter in the filter assembly 2, which helps to simplify the structure of the operating component 3 and eliminates the need to design too many operating components 31.

[0068] The second aspect of this utility model provides a range hood, which includes the above-mentioned filter structure.

[0069] The range hood provided in the second aspect of this utility model has the filter structure provided in the first aspect of this utility model, and thus has all the beneficial effects of the filter structure provided in the first aspect of this utility model.

[0070] In an optional embodiment, the above-mentioned range hood includes a range hood body 5, the range hood body 5 having an exhaust vent, and a filter structure disposed at the exhaust vent.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
