Mounting structure and range hood

Abstract

The utility model relates to a mounting structure and a range hood. The mounting structure comprises an illuminating lamp and a smoke gathering plate. Due to the fact that the flanging structure is matched with the clamping portion in a clamping mode, compared with the mode that the opening wall of the installation opening is matched with the clamping portion in a clamping mode, the length of the flanging structure in the direction perpendicular to the smoke gathering plate is larger than the thickness of the opening wall of the installation opening, and the wall climbing height of the clamping portion is increased. Therefore, the defect that the clamping part slides inwards to enter the inner space of the range hood and abuts against and is clamped with the inner wall of the smoke gathering plate to cause that the clamping part cannot be separated can be effectively overcome, and when the illuminating lamp is pushed from inside to outside, the clamping part is elastically compressed, and the illuminating lamp can be smoothly detached out of the range hood from the mounting opening. In addition, due to the fact that the flanging structure is matched with the clamping portion in a clamping mode, the defect that the clamping portion and the abutting portion of the shell interfere with each other when the length of the spring piece is large can be overcome.

Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and particularly relates to an installation structure and a range hood. Background Art

[0002] A range hood belongs to kitchen electrical equipment and is used to absorb the oil fumes generated during the cooking process. To increase visibility, a lighting lamp is usually installed on the range hood.

[0003] The range hood in the related art includes a smoke collecting plate, and an installation opening adapted to the shape of the lighting lamp is formed on the smoke collecting plate, and the lighting lamp is installed at the installation opening. Among them, a first abutting portion is provided around the panel of the lighting lamp, and a second abutting portion bent toward the inner area of the range hood is provided on the wall of the installation opening. The cross-sectional shape of the second abutting portion is, for example, an L shape, and the second abutting portion and the first abutting portion are abutted and cooperated with each other to play a limiting role on the panel of the lighting lamp, preventing the lighting lamp from being pressed into the inner space of the range hood under an external force. In addition, at least two spring pieces are provided on the outer shell of the lighting lamp, and the opposite two end portions of the spring pieces are respectively clamped with the edges of the second abutting portion, so that the lighting lamp is fixed at the installation opening.

[0004] However, when the length dimension of the spring piece is too short, during the installation and use of the lighting lamp, the end portion of the spring piece is easily separated from the edge of the second abutting portion and slides into the inner space of the range hood. Furthermore, the end portion of the spring piece will abut against the inner wall of the smoke collecting plate, resulting in inconvenience in taking out the lighting lamp from the installation opening by pushing from the inside to the outside, that is, inconvenience in the normal disassembly and removal operation of the lighting lamp; when the length dimension of the spring piece is too long, the end portion of the spring piece will easily interfere with the panel of the lighting lamp.

Furthermore, when the lighting lamp is pushed from the inside to the outside, the clamping part is elastically compressed, and the lighting lamp can be smoothly removed from the mounting opening to the outside of the range hood. In addition, since the flanging structure and the clamping part are engaged with each other, it can prevent the defect of interference between the clamping part and the abutting part of the housing when the length of the spring piece is relatively large.

At the same time, since the clamping portion is snap-fitted with the flanging structure, the lighting lamp is stably mounted on the smoke collecting plate; on the other hand, since the flanging structure is snap-fitted with the clamping portion, compared with the method of snap-fitting the mouth wall of the mounting opening with the clamping portion, the length of the flanging structure in the direction perpendicular to the smoke collecting plate is greater than the thickness of the mouth wall of the mounting opening, that is, the climbing height of the clamping portion is increased, so as to effectively prevent the defect that the clamping portion slides inward into the internal space of the oil fume suction machine and abuts against the inner wall of the smoke collecting plate and gets stuck and cannot be disengaged. Furthermore, when the lighting lamp is pushed from the inside to the outside, the clamping portion is elastically compressed, and the lighting lamp can be smoothly removed from the mounting opening to the outside of the oil fume suction machine.

[0039] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0040] As described in the background technology, the lighting lamp in the related art is not convenient for normal disassembly operation, and the spring sheet and the panel of the lighting lamp are prone to interference. The inventors have found that the reason for this problem is that the edge of the spring sheet and the second abutment portion is in line contact, and the spring sheet is easily deformed under force. When the spring sheet is deformed under force or the size does not meet the requirements, especially during the assembly process, the end of the spring sheet is easily loosened from the edge of the second abutment portion and slides into the inner shell, resulting in the inability to perform normal disassembly operation, or it is too tight and interferes with the panel of the lighting lamp, that is, the risk of installation failure is relatively high.

[0041] Based on the above reasons, the present application provides a mounting structure and a range hood, which can facilitate the normal removal operation of the lighting lamp 10 and avoid the interference between the spring sheet 12 and the panel of the lighting lamp 10.

[0042] See also Figures 1 to 4 An embodiment of the present application provides a mounting structure, which includes: a lighting lamp 10 and a smoke collecting plate 20. The lighting lamp 10 includes a shell 11 and at least one spring sheet 12 mounted on the shell 11. An abutting portion 1121 is provided on the outer periphery of the shell 11. The opposite ends of the spring sheet 12 are provided with clamping portions 121 and are respectively located on opposite sides of the shell 11. The smoke collecting plate 20 is provided with a mounting portion 21 recessed toward the inner space of the range hood and a flange structure 22 connected to the mounting portion 21 and extending toward the inner space of the range hood. The mounting portion 21 is formed with a mounting opening 23. The shell 11 is penetrated into the mounting opening 23. The abutting portion 1121 abuts against the outer side of the mounting portion 21, and the flange structure 22 is respectively clamped and matched with each clamping portion 121.

[0043] It should be noted that the outer side of the mounting portion 21 refers to the side of the mounting portion 21 facing away from the inner space of the range hood, and the inner side of the mounting portion 21 refers to the side of the mounting portion 21 facing the inner space of the range hood.

[0044] In the above-mentioned installation structure, on the one hand, since the abutting portion 1121 abuts against the outer side of the installation portion 21, the installation portion 21 plays a limiting role, and the illuminating lamp 10 cannot be pressed into the internal space of the range hood from the outside to the inside. At the same time, since the clamping portion 121 is clamped with the flange structure 22, the illuminating lamp 10 is firmly installed on the smoke collecting plate 20. On the other hand, since the flange structure 22 is clamped with the clamping portion 121, compared with the installation opening 23 and the clamping portion 121, the installation opening 23 and the clamping portion 121 are more stable. In the snap-fitting mode, the length of the flange structure 22 in the direction perpendicular to the smoke collecting plate 20 is greater than the wall thickness of the installation opening 23, that is, the wall climbing height of the clamping part 121 is increased, so that the clamping part 121 can be effectively prevented from sliding inward into the internal space of the range hood and abutting against the inner wall of the smoke collecting plate 20 to be stuck and unable to escape, and then when the lighting lamp 10 is pushed from the inside to the outside, the clamping part 121 is elastically compressed, and the lighting lamp 10 can be smoothly removed from the installation opening 23 to the outside of the range hood. In addition, since the flange structure 22 and the clamping part 121 are mutually snap-fitted, the interference defect between the clamping part 121 and the abutting part 1121 of the housing 11 caused by the large length of the spring sheet 12 can be prevented.

[0045] In some embodiments, the flange structure 22 can be provided as one and arranged around the circumference of the installation opening 23, so that one flange structure 22 can be engaged with each clamping portion 121 at the same time. Of course, the flange structure 22 can also be provided as multiple flange structures, and each flange structure 22 is engaged with each clamping portion 121. In this way, compared with the method of arranging the flange structure 22 around the circumference of the installation opening 23, it can save materials.

[0046] In some embodiments, the spring pieces 12 include but are not limited to one, two, three or more. When the number of spring pieces 12 is greater, the installation stability of the lighting lamp 10 on the smoke collecting plate 20 can be improved; when the number of spring pieces 12 is less, the number of spring pieces 12 can be saved and the material cost can be reduced. In this embodiment, the spring pieces 12 are specifically, for example, two or three. While ensuring that the lighting lamp 10 can be stably installed on the smoke collecting plate 20, the number of spring pieces 12 is small, thereby reducing the cost.

[0047] See also Figures 2 to 4 In a specific embodiment, there are two spring sheets 12 and four flange structures 22 , and the four flange structures 22 are respectively engaged with the four engaging portions 121 .

[0048] Please refer to Figure 2 、 Figure 3 and Figure 5 or Figure 6 , in one embodiment, the snap - connection part 121 includes a first clamping piece 1211 and a second clamping piece 1212 which are arranged at an angle and connected to each other. The first clamping piece 1211 abuts against the flanging structure 22, and the flanging structure 22 is located below the connection position of the first clamping piece 1211 and the second clamping piece 1212. In this way, not only can the snap - connection part 121 be prevented from popping into the internal space of the range hood, but also the spring piece 12 can be prevented from slipping downwards and disengaging from the snap - connection part 121, that is, the lighting lamp 10 is stably installed on the smoke - collecting plate 20.

[0049] It should be noted that the "flanging structure 22" in this embodiment can be "a part of the mounting part 21", that is, the "flanging structure 22" and the "other parts of the mounting part 21" are integrally formed; or it can be an independent component separable from the "other parts of the mounting part 21", that is, the "flanging structure 22" can be independently manufactured and then combined with the "other parts of the mounting part 21" to form a whole.

[0050] It should be noted that the "first clamping piece 1211" in this embodiment can be "a part of the second clamping piece 1212", that is, the "first clamping piece 1211" and the "other parts of the second clamping piece 1212" are integrally formed; or it can be an independent component separable from the "other parts of the second clamping piece 1212", that is, the "first clamping piece 1211" can be independently manufactured and then combined with the "other parts of the second clamping piece 1212" to form a whole.

[0051] Please refer to Figure 5 and Figure 6 , in some embodiments, the flanging structure 22 is perpendicular to the smoke - collecting plate 20, as Figure 5 shown, while the first clamping piece 1211 is inclined with respect to the smoke - collecting plate 20, so that the flanging structure 22 and the first clamping piece 1211 are in line contact; of course, the flanging structure 22 can also be inclined with respect to the smoke - collecting plate 20 and, for example, be parallel to the first clamping piece 1211 and in surface contact, as Figure 6 shown. Compared with the line - contact method, the clamping stability can be improved.

[0052] In one embodiment, the mounting structure further includes a soft material disposed at the position where the flanging structure 22 and the clamping portion 121 abut against each other, and the soft material is connected to the flanging structure 22 and / or the clamping portion 121. The soft material includes, but is not limited to, being adhesively bonded, clamped, or printed on the flanging structure 22 and / or the clamping portion 121, and can be specifically adjusted and set flexibly according to actual requirements. The soft material can be either a rubber pad, a plastic pad, a coating, or other types of shock-absorbing materials. In this way, under the action of the soft material, the friction force at the contact position between the flanging structure 22 and the clamping portion 121 can be increased, effectively preventing the lighting lamp 10 from falling off, and when installing and disassembling, the noise generated by hard contact between metals can be effectively avoided.

[0053] Please refer to Figure 3 In one embodiment, a first anti-fooling portion 113 is provided on the housing 11, and a second anti-fooling portion 211 that is arranged in cooperation with the first anti-fooling portion 113 is provided on the mounting portion 21. One of the first anti-fooling portion 113 and the second anti-fooling portion 211 is set as a groove, and the other is set as a protruding portion that can be inserted into the groove. In this way, during the installation process, after the first anti-fooling portion 113 and the second anti-fooling portion 211 are aligned with each other and combined together, the lighting lamp 10 can be installed in place on the smoke collecting plate 20, thereby preventing the installation orientation of the lighting lamp 10 from being incorrect and playing an anti-fooling role.

[0054] Please refer to Figure 2 、 Figures 7 to 10 In one embodiment, a card slot 114 that is engaged and cooperated with the mounting portion 21 is formed on the outer periphery of the housing 11. In this way, the card slot 114 can realize the clamping and fixing of the housing 11 on the mounting portion 21. At the same time, the housing 11 is also engaged and cooperated with the flanging structure 22 through the spring piece 12, so that the lighting lamp 10 can be stably installed on the smoke collecting plate 20.

[0055] In some embodiments, the card slot 114 includes, but is not limited to, being formed at one end of the housing 11, and the spring piece 12 straddles the left and right opposite sides of the housing 11. In this way, one end of the housing 11 is clamped and installed on the mounting portion 21, and the left and right opposite sides of the housing 11 are respectively clamped and fixed to the mounting portion 21 through the spring piece 12, so that the lighting lamp 10 is stably installed on the smoke collecting plate 20.

[0056] On the basis of the foregoing embodiments, since the card slot 114 is formed on the outer periphery of the housing 11 and is clamped and fixed to the mounting portion 21 through the card slot 114, the number of spring pieces 12 can be one or two, and the lighting lamp 10 can be stably installed on the smoke collecting plate 20, without using more than three spring pieces 12 as in the prior art. Therefore, the number of spring pieces 12 can be reduced, which plays a role in reducing the material cost, and at the same time, the risk caused by the failure of the spring piece 12 can be reduced.

[0057] In one embodiment, the housing 11 includes a bottom case 111 and a face case 112 installed on the bottom case 111. The outer periphery of the face case 112 protrudes outside the bottom case 111 to form an abutting portion 1121. A pressing portion 1111 is provided on the outer wall of the bottom case 111, and the pressing portion 1111 and the abutting portion 1121 cooperate to form a clamping groove 114.

[0058] Specifically, a plurality of pressing blocks 1112 are provided at intervals on the side of the pressing portion 1111 facing the abutting portion 1121. Each pressing block 1112 is clamped with the mounting portion 21, which can improve the mounting stability of the mounting portion 21. In addition, a guiding inclined surface 1113 is provided on the pressing block 1112. Under the guiding action of the guiding inclined surface 1113, it is convenient to snap the mounting portion 21 into the clamping groove 114.

[0059] In some embodiments, the face case 112 is installed on the bottom case 111 by, for example, snap connection, ultrasonic welding or caulking. Specifically, a plurality of buckles 1122 are provided on the face case 112, and the face case 112 is snap-connected to the bottom case 111 through the buckles 1122. In addition, the lighting device 10 further includes a lamp body installed inside the bottom case 111. The lamp body is, for example, a spot lamp. When the lamp body emits light, the light shines out through the face case 112 to play a lighting role.

[0060] In some embodiments, the spring piece 12 is fixed to the back surface of the bottom case 111 by various fasteners 30 including but not limited to screws, bolts, pins, rivets, etc.

[0061] In some embodiments, the outer side surface of the abutting portion 1121 is flush with the outer wall surface of the smoke collecting plate 20, which can make the appearance of the range hood more beautiful.

[0062] In some embodiments, the mounting portion 21 includes a first connecting portion 212 and a second connecting portion 213 that are connected to each other and arranged at an angle. The first connecting portion 212 and the second connecting portion 213 are, for example, perpendicular to each other, and the second connecting portion 213 is parallel to the outer wall surface of the smoke collecting plate 20. The abutting portion 1121 abuts against the outside of the second connecting portion 213. In addition, the flanging structure 22 is specifically connected to the edge of the second connecting portion 213, for example, by bending the second connecting portion 213 toward the internal space of the range hood.

[0063] Please refer to Figures 1 to 4 , in one embodiment, a range hood includes the mounting structure of any of the above embodiments.

[0064] For the above-mentioned range hood, on the one hand, since the abutting portion 1121 abuts against the outer side of the mounting portion 21, the mounting portion 21 plays a limiting role, preventing the lighting lamp 10 from being pressed into the inner space of the range hood from the outside to the inside. At the same time, since the clamping portion 121 is clamped and matched with the flanging structure 22, the lighting lamp 10 is firmly installed on the smoke collecting plate 20. On the other hand, due to the clamping cooperation between the flanging structure 22 and the clamping portion 121, compared with the way of clamping the clamping portion 121 with the wall of the mounting opening 23, the length of the flanging structure 22 in the direction perpendicular to the smoke collecting plate 20 is greater than the thickness of the wall of the mounting opening 23, that is, the climbing height of the clamping portion 121 is increased, which can effectively prevent the defect that the clamping portion 121 slides inward into the inner space of the range hood and abuts against the inner wall of the smoke collecting plate 20 and gets stuck and cannot be removed. Furthermore, when the lighting lamp 10 is pushed from the inside to the outside, the clamping portion 121 is elastically compressed, and the lighting lamp 10 can be smoothly removed from the mounting opening 23 to the outside of the range hood. In addition, since the flanging structure 22 and the clamping portion 121 are clamped and matched with each other, it can prevent the interference defect between the clamping portion 121 and the abutting portion 1121 of the housing 11 when the length of the spring piece 12 is relatively large.
