Description

Technical Field

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

[0002] In order to prevent the oil smoke from escaping from the two sides, side suction range hoods are generally provided with baffles on both sides. The baffles are fixed on the flaps and follow the flaps to open and close. However, during the movement, the left and right baffles will rub against the edges of the holes of the smoke hood, causing abnormal noise and damaging the surface coating. To solve this problem, usually, limit blocks are provided at the baffle holes to prevent the left and right baffles from rubbing against the edges of the holes of the smoke hood during operation, causing abnormal noise.

[0003] However, the actual baffle is not completely in the center of the smoke hood hole, but is usually offset to one side and rubs against the limit block. When the baffle is offset too much, the friction with the bumps on the limit block is too great, leaving marks on the baffle when the range hood is opened and closed. The marks are powder left on the baffle from the friction of the bumps of the limit block, which not only requires users to clean it, but is also likely to scratch the spray coating on the baffle.

[0006] The fixing portion is connected to the deformable portion, and a deformation gap is provided between the fixing portion and the deformable portion so as to enable the deformable portion to move in a direction away from the baffle.

[0007] Further, along a first direction, the deformation portion, the deformation gap and the fixing portion are arranged in sequence, and the first direction is perpendicular to the baffle.

[0008] Furthermore, two ends of the deformable portion are respectively connected to two ends of the fixed portion, and a hole between the deformable portion and the fixed portion forms a deformation gap.

[0010] Furthermore, the hole is in a strip shape, and the width of the deformation gap gradually increases from the two ends of the deformation portion toward the middle.

[0011] Furthermore, the surface where the deformation portion contacts the baffle is a curved surface.

[0012] Further, along a fourth direction, the deformation portion, the deformation gap and the fixing portion are sequentially arranged, and the fourth direction is parallel to the baffle;

[0013] One end of the deformation part is connected to the fixing part, and the other end of the deformation part is in contact with the baffle.

[0020] When the baffle is tilted, the baffle will squeeze the limiter on the inclined side, and the deformation part on the limiter will be in direct contact with the baffle. After being squeezed by the baffle, due to the deformation gap between the deformation part and the fixed part, the deformation part can produce a larger displacement in the direction away from the baffle, thereby realizing a soft connection between the baffle and the limiter, preventing scratches caused by hard friction between the baffle and the limiter, and causing trouble to users.

[0039] Example 1

[0040] The limiting member 100 provided by the present invention is installed on the left and right sides of the baffle 200 , that is, one limiting member 100 can be installed on each of the left and right sides of the baffle 200 .

[0041] like Figure 1As shown, the limiting member 100 includes: a fixing portion 110 and a deformation portion 120. The fixing portion 110 is used to connect with the smoke collecting hood. The fixing portion 110 can be connected with the smoke collecting hood by means of screws, buckles, adhesives, etc.

[0042] The deformable portion 120 is in contact with the baffle 200. The fixed portion 110 is connected to the deformable portion 120, and a deformation gap 130 is provided between the two so that the deformable portion 120 can move in a direction away from the baffle 200. In this embodiment, the deformable portion 120 moves along a first direction, and the first direction is perpendicular to the baffle 200. It should be noted that the movement trajectory of the deformable portion 120 may be only along the first direction, or the movement trajectory of the deformable portion 120 may contain a sub-trajectory along the first direction, that is, displacement is generated in the first direction. In this embodiment, the first direction is the left-right direction.

[0043] When the baffle 200 is tilted, the baffle 200 will squeeze the limit piece 100 on the tilted side, and the deformation part 120 on the limit piece 100 will be in direct contact with the baffle 200. After being squeezed by the baffle 200, due to the deformation gap 130 between the deformation part 120 and the fixed part 110, the deformation part 120 can produce a larger displacement, thereby realizing a soft connection between the baffle 200 and the limit piece 100, and preventing the baffle 200 and the limit piece 100 from causing scratches due to hard friction, which causes trouble to users.

[0044] Specifically, Figure 1 As shown, in this embodiment, the deformation part 120, the deformation gap 130 and the fixed part 110 are sequentially arranged along the first direction. During the whole process, the fixed part 110 is stationary relative to the smoke collecting hood, and after the deformation part 120 is squeezed by the baffle 200, it moves toward the fixed part 110 along the first direction, and the deformation gap 130 becomes narrower, so that the baffle 200 and the limiter 100 are softly connected, and the pressure is released through the deformation gap 130, so that the baffle 200 is effectively protected.

[0045] In this embodiment, the two ends of the deformable portion 120 are respectively connected to the two ends of the fixed portion 110, and the hole between the deformable portion 120 and the fixed portion 110 forms a deformation gap 130. Both ends of the deformable portion 120 are connected to the fixed portion 110, thereby forming a stable closed loop structure, and the deformable portion 120 can apply uniform pressure to the baffle 200.

[0046] In other feasible solutions, only one end of the deformation portion 120 may be connected to one end of the fixing portion 110 .

[0047] In an practicable solution, the hole formed between the deformable portion 120 and the fixing portion 110 may extend along the second direction, the second direction being perpendicular to the front panel of the smoke hood, and the front panel is provided with a strip hole for the baffle 200 to pass through. Figure 1As shown, the hole between the deformation part 120 and the fixing part 110 may extend along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. Figure 1 As shown, the hole is in a strip shape, and the width of the deformation gap 130 gradually increases from the two ends of the deformation part 120 toward the middle. In other words, the hole between the deformation part 120 and the fixing part 110 is wider in the middle, while narrower on both sides. The middle of the deformation part 120 first contacts the baffle 200, because the gap width in the middle is larger, so it can produce a larger deformation and form a soft contact with the baffle 200.

[0048] The width of the deformation gap 130 may range from 1 mm to 3 mm. If it is too small, there will be a lack of elasticity, and if it is too large, there will be no elasticity.

[0049] The surface where the deformation part 120 contacts the baffle 200 may be a curved surface, and the top of the curved surface contacts the baffle 200. The point contact can reduce the friction between the stopper 100 and the baffle 200, thereby reducing friction and avoiding abnormal noise.

[0050] like Figure 1 and Figure 5 As shown, in this embodiment, a clamping hole 111 may be provided on the fixing portion 110 , and similar to the prior art, the connection between the limiting member 100 and the smoke collecting hood is achieved by clamping the spring piece 310 on the smoke collecting hood with the clamping hole 111 .

[0051] Example 2

[0052] like Figure 2 As shown, in this embodiment, along the fourth direction, the deformation part 120, the deformation gap 130 and the fixing part 110 are sequentially arranged, and the fourth direction is parallel to the baffle 200, that is, the plane where the deformation part 120, the deformation gap 130 and the fixing part 110 are located is parallel to the side of the baffle 200. One end of the deformation part 120 is connected to the fixing part 110, and the end forms a fixed end, and the other end of the deformation part 120 abuts against the baffle 200, and the end forms a free end. Only one end of the deformation part 120 is connected to the fixing part 110, and the deformation amplitude of the free end is larger, so that the baffle 200 and the limiting member 100 are softly connected, and scratches caused by hard friction between the baffle 200 and the limiting member 100 are prevented, which causes trouble to the user.

[0053] In addition to being able to swing, the deformable portion 120 itself can be made of an elastic material such as rubber. The deformable portion 120 has elastic deformation along a direction perpendicular to the baffle 200, thereby further increasing the elastic displacement.

[0054] Example 3

[0055] In the prior art, a limit piece 100 is provided on each side of the baffle 200. The two limit pieces 100 need to be installed twice by employees, and the four limit pieces 100 of the whole machine need to be installed four times by employees. The labor intensity is increased and the failure rate is also increased. Therefore, in this embodiment, the two limit pieces 100 on both sides of the original baffle 200 are combined into one limit piece 100.

[0056] like Figure 3 - Figure 5 As shown, specifically, the fixing portion 110 may include a first fixing portion 410 located on one side of the baffle 200, and a second fixing portion 420 located on the other side of the baffle 200. One end of the first fixing portion 410 and one end of the second fixing portion 420 are connected to the outer side of the edge of the baffle 200, and the first fixing portion 410 and the second fixing portion 420 are connected to form a "U" shape. The deformation portion 120 includes a first abutting structure 430 abutting against one side of the baffle 200, and a second abutting structure 440 abutting against the other side of the baffle 200. There is a first deformation gap 450 between the first abutting structure 430 and the first fixing portion 410, so that the first abutting structure 430 can move in the first direction; there is a second deformation gap 460 between the second abutting structure 440 and the second fixing portion 420, so that the second abutting structure 440 can move in the first direction. The first abutting structure 430 and the second abutting structure 440 may be the same or different. By connecting the first fixing portion 410 and the second fixing portion 420 on both sides of the baffle 200 together, the limiting of both sides of the baffle 200 can be achieved by only one installation.

[0057] A base 470 for bonding to the smoke hood can be provided below the fixing portion 110 of the limiting member 100. The shape of the base 470 is consistent with the shape of the bonding position on the smoke hood, thereby increasing the contact area with the smoke hood, that is, increasing the bonding surface, making it firmly bonded.

[0058] In this embodiment, the forms of the first deformation gap 450 and the second deformation gap 460 may be the same as the form of the deformation gap 130 in the first or second embodiment.

[0059] The range hood provided by the utility model includes the above-mentioned position-limiting member 100. Since the range hood provided by the utility model uses the above-mentioned position-limiting member 100, the range hood provided by the utility model also has the advantages of the position-limiting member 100.

[0060] The smoke collecting hood is provided with a strip hole for the baffle 200 to pass through, the strip hole extends from the top and the bottom, and the limiting member 100 is installed at the side position of the lower end of the strip hole.

[0061] like Figure 6As shown, the baffle 200 is a fan-shaped structure, which opens and closes together with the air guide plate. The edge fixed to the air guide plate is the upper edge. The limit member 100 is located at point C and point D (point C is closer to the upper end of the smoke hood than point D), which can protect the baffle 200. When the baffle 200 is deflected, the force at point C is greater than that at point D, and the degree of surface damage of the baffle 200 is also greater than that at point D. Therefore, setting the limit member 100 at point D can reduce damage to the baffle 200.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
