Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a rectifier plate mounting structure of a range hood and the range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. Generally, range hoods include top suction type and side suction type, and top suction type range hoods are more and more widely used due to their advantages such as being neat, light, and taking up little space. Top suction type range hoods generally include a smoke hood, a fan housing located on the smoke hood, and a centrifugal fan installed in the fan housing. For example, a Chinese invention patent application with application number CN200910096759.3 (authorization announcement number CN101514823B) discloses a range hood with a smoke guide plate, including a body, a smoke hood, and a smoke guide plate. An air inlet is provided at the bottom of the smoke hood, and a smoke guide plate (also called a rectifier plate) is arranged opposite to the air inlet and maintains a predetermined distance from the smoke hood, thereby forming a smoke channel for the smoke to pass through between the smoke guide plate and the smoke hood.

[0003] In order to facilitate the convenient installation of the smoke guide plate, in the Chinese utility model patent application with application number CN201921095741.7 (authorization announcement number: CN210861244U), a structure in which the smoke guide plate is detachably connected to the smoke hood (a push rod fixed on the smoke hood) through a snap-on assembly is disclosed, wherein a snap-on is provided at the end of the output end of the electric push rod, and snap-on sockets for cooperating with the snap-on are respectively provided on the upper surface of the corresponding smoke baffle plate facing the smoking port.

[0004] The existing range hoods with oil guide plates have improved the oil fume extraction performance due to the application of the smoke guide plates, but the installation structure of the snap-on assembly of the smoke guide plates still has certain shortcomings. Usually, the snap-on socket uses a through hole that passes through the slot from the outer surface of the socket body as an installation channel for installing springs and steel balls. After the springs and steel balls are installed, a screw plug is used to limit the position at the outer port. In order to prevent the screw plug from being exposed, some also use decorative stickers to cover it. This installation method, on the one hand, has more design parts, and a complex structure, many small parts, a long installation labor time, and a high cost. On the other hand, oil stains are also easy to accumulate in the gap between the ordinary exposed screw plug and the edge of the decorative sticker, which greatly prolongs the user's cleaning time and reduces the user's experience.

[0005] Therefore, the rectifier plate mounting structure of the existing range hood needs to be further improved. Utility Model Content

[0006] The first technical problem to be solved by the utility model is to provide a rectifier plate installation structure for a range hood in view of the current status of the prior art, wherein the rectifier plate installation structure can effectively simplify the assembly structure of the snap assembly and facilitate cleaning.

[0007] The second technical problem to be solved by the utility model is to provide a range hood using the above-mentioned rectifier plate installation structure in view of the current status of the prior art.

[0008] The technical solution adopted by the utility model to solve the first technical problem is: a rectifier plate installation structure of a range hood, comprising:

[0009] Fume hood;

[0010] The rectifier plate is mounted on the smoke collecting hood via a snap assembly, wherein the snap assembly comprises a snap piece provided on the rectifier plate and a snap seat provided on the smoke collecting hood and capable of engaging with the snap piece;

[0011] The buckle member has a claw, and the claw has a limiting recess, the buckle seat includes a seat body and a limiting buckle, the seat body has a plug-in channel for the claw of the buckle member to be inserted into it and an installation chamber for accommodating the limiting buckle, the limiting buckle has a convex block that can be correspondingly inserted into the limiting recess of the claw, the installation chamber is connected with the plug-in channel, and a movable opening is formed for the convex block of the limiting buckle to enter and exit the plug-in channel, and an installation opening for the limiting buckle to be installed in the installation chamber is formed at one end of the seat body that abuts against the smoke hood;

[0012] An elastic member is also provided in the installation chamber, and the elastic member acts on the limit buckle and makes the protrusion of the limit buckle always have a tendency to move toward the plug-in channel; or,

[0013] The main body of the position-limiting buckle is an elastic buckle structure that can bend and deform under the action of external force and automatically reset after the external force is released.

[0014] In order to facilitate the installation of the limiting buckle into the seat body, the limiting buckle is overall plate-shaped and is vertically arranged in the plug-in channel.

[0015] As an improvement, the protrusion is arranged on a side of the main body of the limiting buckle facing the plug-in channel.

[0016] Taking into account that a portion of the protrusion protrudes outward relative to the main body of the limiting buckle, in order to achieve smooth assembly of the limiting buckle, the movable opening on the seat body extends upward to the position of the installation opening to form a semi-closed opening structure with a closed lower end and an open upper end, and the protrusion of the limiting buckle can slide up and down along the installation opening.

[0017] In order to prevent the limit buckle from moving up and down or shaking, when the limit buckle is installed in place in the installation chamber, the upper end of the limit buckle abuts against the smoke collecting hood.

[0018] In order to facilitate the connection with the smoke collecting hood, a screw connection hole for installing a screw is also opened on the top of the seat body.

[0019] In order to facilitate the claws of the latch to smoothly enter and exit the plug-in channel, the outer wall surface of the protrusion of the limit buckle is constructed with a guiding inclined surface or a guiding arc surface.

[0020] The above-mentioned elastic part can adopt various existing technologies and may include various elastic elements such as compression springs, torsion springs, and spring leaves. However, in order to better cooperate with the above-mentioned limit buckle, the elastic part is a spring, one end of which is against the side of the limit buckle away from the plug-in channel, and the other end is against the inner wall of the installation chamber.

[0021] In order to facilitate the radial and secure positioning of the spring, a positioning groove for limiting the end of the spring is provided on the side of the limiting buckle away from the plug-in channel in the area opposite to the protrusion.

[0022] As an improvement, the limit buckle is an elastic buckle structure, which is plate-shaped as a whole and is arranged vertically in the plug-in channel. The main body of the limit buckle also has a folded edge that bends and extends in a direction away from the plug-in channel, and the end of the folded edge abuts against the inner wall of the installation chamber. The protrusion and the folded edge are staggered in the length direction of the main body of the limit buckle. The folded edge of the limit buckle can provide an opposite force when the main body of the limit buckle is deformed, ensuring that the limit buckle can be reset in time after deformation.

[0023] In order to ensure the reliability of the connection of the snap assembly, there are two installation chambers on the seat body, which are located on the opposite sides of the plug-in channel respectively. There are also two corresponding limit buckles, which are respectively arranged in the two installation chambers. There are also two relatively arranged limit recesses on the claws of the snap member.

[0024] The technical solution adopted by the utility model to solve the second technical problem is: a range hood, including a smoke collecting hood, an air inlet is opened at the bottom of the smoke collecting hood, a rectifier plate is provided below the air inlet of the smoke collecting hood, and the rectifier plate and the smoke collecting hood are connected through the above-mentioned rectifier plate mounting structure of the range hood.

[0025] Compared with the prior art, the advantages of the utility model are as follows: the limit buckle can be arranged in the installation chamber of the seat body through the installation opening, and there is no need to open a through hole for installing the screw plug as in the prior art. Compared with the existing buckle installation structure, this combination of hidden limit buckles reduces the number of components such as screw plugs and screw plug decorative stickers, making the appearance simple, the appearance components do not have multiple colors, and are more unified and beautiful; on the other hand, it also reduces the accumulation of oil in the gaps at the edges of ordinary exposed screw heads and decorative stickers, reduces the user's cleaning time, and improves the cleaning experience and appearance.

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0036] Figure 1-Figure 6The installation structure of the rectifier plate of the range hood of the utility model and a preferred embodiment of the range hood are shown. The range hood includes a smoke collecting hood 2 and a rectifier plate 1. An air inlet is provided at the bottom of the smoke collecting hood 2. The rectifier plate 1 is provided below the air inlet corresponding to the smoke collecting hood 2. The rectifier plate 1 is basically arranged horizontally. The front part of the rectifier plate 1 is connected to the smoke collecting hood 2 through two groups of buckle components arranged at intervals on the left and right, and the rear part is connected to the smoke collecting hood 2 through hook 12 components arranged at intervals on the left and right.

[0037] The bottom of the smoke hood 2 is provided with a support arm 23 extending downward, and the bottom of the support arm 23 has a horizontally extending crossbar 230. The rear part of the back of the rectifier 1 is provided with a hook 12 bent and extended backward. When installing, the hook 12 of the rectifier can be hung on the crossbar 230 of the smoke hood 2. The above-mentioned hook 12, support arm 23 and crossbar 230 together constitute the above-mentioned hook 12 assembly.

[0038] The snap assembly includes a snap member 11 and a snap seat 20. The snap member 11 is mounted on the back of the rectifier plate 1 and is rod-shaped and substantially perpendicular to the rectifier plate 1. The end of the snap member 11 is set as a cone head 1111 structure, and a limiting recess 1110 is provided at a position adjacent to the cone head 1111. There are two limiting recesses 1110, which are arranged back to back, that is, the opening directions of the two limiting recesses 1110 are opposite.

[0039] The buckle seat 20 includes a seat body 200 and a limit buckle 21. The seat body 200 is flat as a whole. The seat body 200 has a plug-in channel 201 for the claw 111 of the buckle 11 to be inserted therein and an installation chamber 202 for accommodating the limit buckle 21. There are two installation chambers 202, which are respectively located on opposite sides of the plug-in channel 201. There are two limit buckles 21, each of which is a long plate-like structure as a whole, and is vertically installed in the installation chamber 202. The top of the seat body 200 (that is, the end against which the smoke hood 2 abuts) is formed with an installation port 204 for the limit buckle 21 to be installed in the installation chamber 202. The main body of the limiting buckle 21 has a protrusion 210 on the side facing the plug-in channel 201, which protrudes toward the plug-in channel 201 and can be correspondingly engaged with the limiting recess 1110 of the claw 111. The protrusion 210 is a columnar structure with a guiding arc surface (of course, it can also be set to a wedge-shaped structure with a guiding inclined surface), which can form a guiding match with the cone head 1111 part of the claw 111 of the latch 11, so as to facilitate the insertion of the claw 111 into the plug-in channel, and also enable the protrusion 210 to be easily disengaged from the limiting recess 1110 of the claw 111, so that the claw 111 can smoothly exit the plug-in channel.

[0040] The installation chamber 202 is also connected to the plug-in channel 201, and a movable opening 203 is formed for the protrusion 210 of the limit buckle 21 to enter and exit the plug-in channel 201. In the preferred embodiment, considering that the protrusion 210 protrudes outward relative to the main body of the limit buckle 21, in order to achieve the smooth assembly of the limit buckle 21, the movable opening 203 on the seat body extends upward to the location of the installation opening 204 to form a semi-closed opening structure with a closed lower end and an open upper end. The length dimension of the protrusion 210 on the limit buckle 21 is slightly smaller than the width dimension of the main body of the limit buckle 21, and is arranged close to the lower end of the main body of the limit buckle 21. When installing the limit buckle 21, the protrusion 210 of the limit buckle 21 can slide downward along the installation opening 204, and after being installed in place, the protrusion 210 abuts against the lowest edge of the movable opening 203, and the upper end of the main body of the limit buckle 21 is basically flush with the top surface of the seat body 200. In this way, after the seat body 200 is fixed on the smoke hood 2, the upper end of the limit buckle 21 can abut against the bottom wall of the smoke hood 2, thereby avoiding the limit buckle 21 from moving up and down or shaking.

[0041] The main body of the position-limiting buckle 21 of this embodiment is an elastic buckle structure that can bend and deform under the action of external force and automatically reset after the external force is released. For example, the main body of the position-limiting buckle 21 can be made of metal or plastic. The main body of the position-limiting buckle 21 also has a folded edge 212 that bends and extends in a direction away from the plug-in channel 201, wherein the end of the folded edge 212 abuts against the inner wall of the installation chamber 202, and the protrusion 210 and the folded edge 212 are staggered in the length direction of the main body of the position-limiting buckle 21, such as Figure 2 As shown, the folded edge 212 of the limiting buckle 21 is located at the upper part, and the protrusion 210 is located at the lower part. The folded edge 212 of the limiting buckle 21 can provide an opposite force when the main body of the limiting buckle 21 is deformed, ensuring that the limiting buckle 21 can be reset in time after deformation.

[0042] The top of the seat body 200 is also provided with a screw connection hole 205 for installing a screw. Figure 6 Two screw connection holes 205 are provided on the top of the seat body 200, and the two screw connection holes 205 are correspondingly located at two end positions far away from the top of the seat body 200. Through holes are also provided on the wall of the smoke hood 2, and screws can pass through the through holes from the inside of the smoke hood 2 and connect with the screw connection holes 205 on the seat body 200.

[0043] When installing the snap seat 20, you only need to insert the limit buckle 21 into the installation chamber 202 of the seat body 200 from top to bottom. After it is inserted into place, the protrusion 210 of the limit buckle 21 is against the lower edge of the movable opening 203, and the upper end is basically flush with the top of the seat body 200. Then, the seat body 200 is fixed to the smoke hood 2 by two screws. The lower surface of the smoke hood 2 after being fixed can further prevent the limit buckle 21 from falling out. The overall parts are further reduced, the installation steps are also simplified, and there is no gap for decorative stickers on the outside, which is convenient for cleaning.

[0044] Example 2

[0045] Figure 7 and Figure 8 The installation structure of the rectifier plate 1 of the range hood of the utility model and another preferred embodiment of the range hood are shown. The difference between this embodiment and the first embodiment is that the structure of the buckle seat 20 is different, specifically the structure of the limit buckle 21 is different, and an elastic member 22 is added to provide elastic support for the limit buckle 21, while the structure of the seat body 200, the buckle member 11 and other structures are the same as those in the first embodiment.

[0046] Specifically, an elastic member 22 is further provided in the installation chamber 202. The elastic member 22 is a spring. One end of the spring abuts against the side of the limit buckle 21 away from the plug-in channel 201, and the other end abuts against the inner wall of the installation chamber 202. More specifically, a positioning groove 213 for the end of the spring to be limited therein is provided on the side of the limit buckle 21 away from the plug-in channel 201. The positioning groove 213 is located in the area opposite to the protrusion 210. Under the elastic force of the spring, the protrusion 210 of the limit buckle 21 always has a tendency to move toward the plug-in channel 201. Therefore, the folded edge 212 of the limit buckle 21 in Example 1 can also be omitted accordingly.
