DETAILED DESCRIPTION

[0033] In the following description, numerous specific details are provided for a thorough understanding of the present application. One of ordinary skill in the art will recognize, however, that the application can be practiced without one or more of these specific details. In other instances, well-known structures and processes have not been described in order not to obscure the application.

[0034] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0035] The embodiments of the present application provide a flap assembly. The flap assembly provided by the present application can be applied to a range hood. Hereinafter, a flap assembly according to the embodiments of the present application will be introduced in detail in combination with the accompanying drawings.

[0036] In combination with the accompanying drawings Figures 1a to 6The flap assembly 10 can include a panel 110, a glue layer 120 and a backing plate 130. The backing plate 130 can be arranged on the back of the panel 110 through the glue layer 120. The backing plate 130 can have a connecting surface 131 and a far surface 132 opposite to the connecting surface 131. The connecting surface 131 can be bonded with the glue layer 120. The far surface 132 can have a hinge portion 133 thereon. The backing plate 130 can have a through hole 134 arranged on the side of the hinge portion 133. The through hole 134 can pass through from the far surface 132 to the connecting surface 131. The glue layer 120 can have an upper edge 121, and the glue layer 120 can form a groove 122 below the upper edge 121 corresponding to the through hole 134. Two opposite groove side walls 1221 of the groove 122 can be connected with the upper edge 121 through a first inclined portion 1251 and a second inclined portion 1252 respectively.

[0037] The glue layer 120 can be composed of silicone glue. The silicone glue has high temperature resistance and durability, effectively ensuring the firmness of the paste between the backing plate 130 and the panel 110. Of course, the glue layer 120 can also be composed of other materials. The silicone glue has a thickness of 0.5-1mm after cold curing. The backing plate 130 itself also has a certain thickness, which is generally about 1.2mm.

[0038] The flap assembly 10 of the utility model, through forming the groove 122 below the upper edge 121 of the glue layer 120 corresponding to the through hole 134, the two opposite groove side walls 1221 of the groove 122 are connected with the upper edge 121 through the first inclined portion 1251 and the second inclined portion 1252 respectively, when the flap assembly 10 is applied to the range hood 1, the oil stains flowing above the backing plate 130 will flow along the upper edge 121 of the glue layer 120, along the first inclined portion 1251 and the second inclined portion 1252 into the groove 122, and then flow into the oil cup 30 from the through hole 134, avoiding the oil stains flowing to the outside of the oil cup 30, causing the panel 110 to appear oil hanging or even oil dripping, and without the need to install other structural parts, saving the manufacturing cost and improving the user's use experience.

[0039] The end of the backing plate 130 close to the oil cup 30 can be provided with a turned edge portion 138. The turned edge portion 138 can be tilted at a certain angle relative to the backing plate 130 in the direction away from the panel 110. In this way, it is effectively ensured that the oil stains flowing down from the backing plate 130 can completely flow into the oil cup 30, avoiding the oil stains flowing to the outside of the oil cup 30, causing the panel 110 to appear oil hanging or even oil dripping. The turned edge portion 138 can be a separate structure from the backing plate 130. Specifically, the turned edge portion 138 can be connected with the backing plate 130 by snap connection, screw connection or the like. At this time, the user can disassemble and assemble the separate turned edge portion 138, so as to facilitate the user to clean and maintain the turned edge portion 138. Of course, the turned edge portion 138 can also be connected with the backing plate 130 as an integral structure by welding, one-piece molding or the like.

[0040] With reference to Figure 1a , Figure 2 and Figure 6 , the backing plate 130 can have two side edges 135 and a bottom edge 136 connected between the two side edges 135. The glue layer 120 can have two first side portions 1231 coated along the two side edges 135 respectively and a first bottom portion 1232 coated along the bottom edge 136. The two first side portions 1231 can be connected by the first bottom portion 1232 to form a first glue portion 123. In this way, not only the glue coating operation is facilitated, but also the adhesion between the backing plate 130 and the face plate 110 is ensured.

[0041] With reference to Figures 2 to 5 , the first side portion 1231 can have a first top end 1231a away from the first bottom portion 1232. The first top end 1231a can form a part of the upper edge 121. The first inclined portion 1251 can be connected with the first top end 1231a, and an included angle θ between the first inclined portion 1251 and the reverse extension line of the first top end 1231a can be 5°< θ < 90°. For example, the included angle θ can be 8°, 45°, 85°, etc. When the included angle θ between the first inclined portion 1251 and the reverse extension line of the first top end 1231a is within the range, the oil stains above the backing plate 130 can be effectively guided into the groove 122. In an embodiment of the utility model, the included angle θ is 45°, at this time, the oil stains above the backing plate 130 can be more effectively guided into the groove 122.

[0042] With reference to Figures 2 to 6 , the first side portion 1231 can have a first side outer edge 1231b away from the through hole 134. The first side outer edge 1231b and the side edge 135 can have a first distance L1, 0mm≤L1≤10mm. For example, the first distance L1 can be 0mm, 5mm, 10mm, etc. When the first distance L1 is within the range, not only the glue coating operation is facilitated and glue overflow is avoided, but also the backing plate 130 and the face plate 110 do not form a too large gap at the two side edges 135 of the backing plate 130, so that the oil stains above the backing plate 130 flow out of the oil cup 30 from the gap. In an embodiment of the utility model, the first distance L1 is 5mm, at this time, not only the glue coating operation is facilitated and glue overflow is avoided, but also the backing plate 130 and the face plate 110 do not form a too large gap at the two side edges 135 of the backing plate 130, so that the oil stains above the backing plate 130 flow out of the oil cup 30 from the gap.

[0043] With reference to Figures 1a to 6The gasket 130 can have a top edge 137 opposite to the bottom edge 136. The first side portion 1231 can have a first top end 1231a away from the first bottom portion 1232. The first top end 1231a and the top edge 137 can have a second distance L2, 0mm≤L2≤5mm. For example, the second distance L2 can be 0mm, 2.5mm, 5mm, etc. The second distance L2 in this range not only facilitates the glue operation and avoids glue overflow, but also avoids the gasket 130 and the panel 110 forming a too large gap above the first top end 1231a, so that the oil stains above the gasket 130 flow out of the oil cup 30 along the two sides of the gasket 130. In an embodiment of the utility model, the second distance L2 is 2.5mm, at this time, not only facilitates the glue operation and avoids glue overflow, but also effectively avoids the gasket 130 and the panel 110 forming a too large gap above the first top end 1231a, so that the oil stains above the gasket 130 flow out of the oil cup 30.

[0044] With reference to Figures 2 to 6 The first bottom portion 1232 can have a first bottom outer edge 1232a away from the through hole 134. The first bottom outer edge 1232a and the bottom edge 136 can have a third distance L3, 0mm≤L3≤10mm. For example, the third distance L3 can be 0mm, 5mm, 10mm, etc. The third distance L3 in this range not only facilitates the glue operation and avoids glue overflow, but also avoids the gasket 130 and the panel 110 forming a too large gap below the first bottom outer edge 1232a, so that the oil stains adhere to the gap, causing the problem of not easy to clean. In an embodiment of the utility model, the third distance L3 is 5mm, at this time, not only facilitates the glue operation and avoids glue overflow, but also effectively avoids the gasket 130 and the panel 110 forming a too large gap below the first bottom outer edge 1232a, so that the oil stains adhere to the gap, causing the problem of not easy to clean.

[0045] With reference to Figure 2 And Figure 6 The through hole 134 can have two hole side walls 1341 and a bottom wall 1342 connected between the two hole side walls 1341. The glue layer 120 can have two second side portions 1241 coated along the two hole side walls 1341 respectively and a second bottom portion 1242 coated along the bottom wall 1342. The two second side portions 1241 and the second bottom portion 1242 can be connected to form a second glue portion 124. The second glue portion 124 can enclose the groove 122. In this way, not only the glue operation is facilitated, but also the firmness between the gasket 130 and the panel 110 is ensured, and the oil stains introduced into the groove 122 can flow out from the bottom wall 1342 of the through hole 134.

[0046] Again with reference to Figure 2 And Figure 6One of the two hole side walls 1341 can be connected to the hinge part 133. As shown in Figure 4 The one of the two second side parts 1241 closer to the hinge part 133 can be defined as a connecting side part 1241a. The connecting side part 1241a can have a protruding part 1241b protruding towards the through hole 134. In this way, the firmness of the pasting between the lining plate 130 and the face plate 110 is further ensured, and the oil dirt introduced into the groove 122 can be smoothly drained from the through hole 134.

[0047] The hinge part 133 can be connected with a rocker arm (not shown in the figure). The rocker arm can drive the flap assembly 10 to rotate, so as to switch the flap assembly 10 between the open state and the closed state. When the flap assembly 10 is not needed to be used, the flap assembly 10 can be rotated to the closed state by the rocker arm; when the flap assembly 10 needs to be used, for example, the oil fume needs to be sucked during the cooking process, the flap assembly 10 can be rotated to the open state by the rocker arm, so that the flap assembly 10 guides the oil fume to avoid the oil fume from escaping. Understandably, in the process of driving the flap assembly 10 to rotate by the rocker arm, the connecting side part 1241a bears the maximum force, and the setting of the protruding part 1241b can improve the structural strength of the connecting side part 1241a, so as to avoid the situation that the connecting side part 1241a is easily damaged by force.

[0048] In combination with Figures 3 to 5 The protruding part 1241b can have a protruding size H relative to the hole side wall 1341, 0mm≤H≤2mm. For example, the protruding size H can be 0mm, 1mm, 2mm, etc. The protruding size H in this range not only can improve the firmness of the pasting between the lining plate 130 and the face plate 110, but also can ensure that the oil dirt introduced into the groove 122 can be smoothly drained from the through hole 134. In an embodiment of the utility model, the protruding size H is 1mm, at this time, not only can the firmness of the pasting between the lining plate 130 and the face plate 110 be effectively improved, but also the oil dirt introduced into the groove 122 can be effectively ensured to be smoothly drained from the through hole 134.

[0049] In combination with Figures 3 to 5 The second side part 1241 can have a width M, 0mm≤M≤40mm. For example, the width M can be 0mm, 20mm, 40mm, etc. When the width M is in this range, the firmness of the pasting between the lining plate 130 and the face plate 110 is effectively ensured. In an embodiment of the utility model, the width M is 20mm, at this time, the firmness of the pasting between the lining plate 130 and the face plate 110 is more effectively ensured.

[0050] In combination with Figures 3 to 5The second bottom 1242 can have a width N, 0mm≤N≤40mm. For example, the width N can be 0mm, 20mm, 40mm, etc. When the width N is within the range, the adhesion between the backing plate 130 and the panel 110 is effectively ensured. In an embodiment of the present application, the width is 20mm, which more effectively ensures the adhesion between the backing plate 130 and the panel 110.

[0051] With reference to Figures 2 to 5 The adhesive layer 120 can include a third adhesive part 125 formed between the second adhesive part 124 and the first adhesive part 123. The first inclined part 1251 and the second inclined part 1252 can be located on the third adhesive part 125. In this way, not only is the adhesion between the backing plate 130 and the panel 110 further enhanced, but the first inclined part 1251 and the second inclined part 1252 are also facilitated to be formed. Specifically, the first adhesive part 123 can be applied on the backing plate 130 first, then the second adhesive part 124 is applied, and finally the third adhesive part 125 is applied between the first adhesive part 123 and the second adhesive part 124. In this way, the gluing operation is facilitated. Of course, the second adhesive part 124 can be applied first, then the first adhesive part 123 is applied, and finally the third adhesive part 125 is applied. The third adhesive part 125 can completely cover the area between the first adhesive part 123 and the second adhesive part 124. In this way, the adhesion between the backing plate 130 and the panel 110 is effectively ensured. The third adhesive part 125 can also completely cover the edges of the area between the first adhesive part 123 and the second adhesive part 124. In this way, the oil flowing into the gap between the backing plate 130 and the panel 110 is avoided, which causes the oil to adhere to the gap, making it difficult to clean, and the adhesive material is saved.

[0052] With reference to Figures 2 to 5 The first side 1231 can have a first top end 1231a away from the first bottom 1232. The second side 1241 can have a second top end 1241c away from the second bottom 1242. The first inclined part 1251 can be connected between the first top end 1231a and the second top end 1241c. In this way, part of the oil flowing above the backing plate 130 can flow smoothly into the groove 122 under the guidance of the first inclined part 1251.

[0053] With reference to Figures 2 to 5 The backing plate 130 can have a top edge 137 opposite the bottom edge 136. The third adhesive part 125 can have a third top end 1253 flush with the top edge 137. The second inclined part 1252 can be connected to the third top end 1253 and opposite the first inclined part 1251. In this way, part of the oil flowing above the backing plate 130 can flow smoothly into the groove 122 under the guidance of the second inclined part 1252.

[0054] In some implementations, the second top end 1241c can have a first side 1241d and a second side 1241e.

[0055] As shown exemplarily, Figure 3 the first inclined portion 1251 can be connected between the first top end 1231a and the first side 1241d of the second top end 1241c. The second inclined portion 1252 can be connected between the third top end 1253 and the first side 1241d of the second top end 1241c.

[0056] As shown exemplarily, Figure 3 the first inclined portion 1251 can be connected between the first top end 1231a and the second side 1241e of the second top end 1241c. The second inclined portion 1252 can be connected between the third top end 1253 and the second side 1241e of the second top end 1241c.
