Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a mounting structure for an oil net of a range hood. Background Art

[0002] During operation, oil smoke enters the range hood through the smoke inlet, and an oil net (or grille) is usually provided at the smoke inlet to block some solid impurities or oil in the oil smoke from entering the range hood. At the same time, the oil net (or grille) can guide oil in the oil path.

[0003] The traditional oil net (or grille) is non-removable, and its outer surface can only be scrubbed when cleaning, which may not be clean. For this reason, people have designed a detachable oil net installation structure, such as fixing it with bolts and other connectors, but the bolts are more troublesome when disassembling and assembling. There are also buckle structures such as bumpers for connection, such as the Chinese utility model patent "Ranger hood with air inlet mesh plate that is easy to disassemble and assemble" with patent number 202121433322.7 (authorization announcement number CN215446592U), which includes a smoke hood with an air inlet, an air inlet mesh plate arranged on the air inlet, a wind cabinet arranged on the smoke hood, and a fan arranged in the wind cabinet; a base frame located on the inner side of the air inlet is provided in the smoke hood, and the air inlet mesh plate and the base frame are connected by a quick-release structure; the quick-release structure includes a mounting hole arranged on the base frame and a buckle arranged on the air inlet mesh plate and opposite to the mounting hole, and the buckle is arranged in the mounting hole.

[0004] The existing snap connection structure has an excessively large opening and closing force during the disassembly and assembly process, which causes the oil stains on the oil net to splash off during the disassembly process, affecting the user experience. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a mounting structure for an oil net on a range hood in view of the current status of the prior art, so as to facilitate the disassembly and assembly of the oil net.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a mounting structure of an oil net on a range hood, comprising:

[0007] The housing has a smoke inlet, and the smoke inlet is oriented downward;

[0008] An oil screen is disposed horizontally at the smoke inlet of the shell;

[0009] Features:

[0010] The side of the oil net is provided with a tongue extending upward;

[0011] A limiting component is provided at the edge of the smoke inlet of the housing, and the limiting component includes:

[0012] A socket fixed relative to the housing is provided with a plug hole extending up and down for the tongue of the oil net to be inserted therein, and a through hole penetrating the wall thickness is provided on the side wall of the plug hole;

[0013] A limiting column is longitudinally inserted into the through hole and can move relative to the through hole;

[0014] An elastic member acts on the limiting column so that the head of the limiting column always has a tendency to move toward the insertion hole and press the tongue piece tightly into the insertion hole;

[0015] And under the action of external force, the tongue piece can overcome the action force of the limiting column and move downward and detach from the socket.

[0016] In this way, when the oil net needs to be installed, the user can move the oil net upwards so that the tongue on the oil net is inserted into the socket of the socket and is tightened by the limit column to constrain the oil net at the smoke inlet of the shell; conversely, when the oil net needs to be removed, the user can directly move the oil net downwards, and the tongue on the oil net can be detached from the socket, making operation easier.

[0017] At the same time, compared with the snap-connection method in the prior art, the oil net of the utility model has a smaller opening and closing force during the disassembly and assembly process, which can prevent oil stains on the oil net from splashing and improve the user experience.

[0018] In order to improve the overall structural stability, preferably, the tongue piece is partially concave to form a groove for the head of the limiting column to be inserted into. The cooperation between the groove and the head of the limiting column enables the limiting column to better press the tongue piece into the insertion hole.

[0019] The portion of the tongue piece located above the groove may be vertical, and preferably, the portion of the tongue piece located above the groove is an arc-shaped body arched toward the limiting column. The arc-shaped body can ensure the limiting position of the oil screen after installation, and facilitates the upper end of the tongue piece to extend into the socket of the socket and pass between the limiting column and the inner wall of the socket.

[0020] Preferably, the end surface of the head of the limiting column has:

[0021] The vertical surface located in the center is inserted into the groove, and the direction of the vertical surface is backward;

[0022] A first curved surface extending upward and forward from an upper edge of the vertical surface, and contacting the upper side wall of the groove in a tangential manner;

[0023] The second curved surface extending downward and forward from the lower edge of the vertical surface contacts the lower side wall of the groove in a tangential manner.

[0024] In this way, the upper and lower limits of the oil net after installation can be guaranteed, and it is beneficial for the upper end of the tongue to extend into the plug hole of the socket and pass through between the limit column and the inner wall of the plug hole.

[0025] Furthermore, the bottom wall of the groove extends vertically, and the part of the side wall of the insertion hole opposite to the through hole is a vertical wall, so that the limiting column can better press against the tongue piece.

[0026] Furthermore, the first curved surface and the second curved surface are symmetrically arranged with the central axis of the limiting column as the center.

[0027] Furthermore, the socket is provided with a mounting cavity located at the front side of the jack, for the limiting column to be constrained therein;

[0028] The elastic member is a spring extending forward and backward and is arranged between the limiting column and the side wall of the installation cavity.

[0029] In the above schemes, preferably, there are at least two tongues, which are arranged at intervals along the circumferential direction, and the number of the limit assemblies is consistent with the number of the tongues, and they are arranged corresponding to the respective tongues. Of course, in addition to this, there may be only one tongue, in which case, in order to ensure the stability of the installation structure, the tongue may be in the shape of a long strip extending along the edge of the oil net.

[0030] In order to further facilitate disassembly and assembly, preferably, the tongue is provided on the front side of the oil net, the rear side of the oil net is provided with a pin extending backward, and a socket is provided on the housing adjacent to the rear side of the smoke inlet, so that the pin can be inserted into the socket and rotated up and down relative to the socket. When installing the oil net, first insert the pin into the socket, then rotate the oil net upward until the tongue on the oil net is inserted into the socket of the socket; conversely, when removing the oil net, first rotate the oil net downward so that the tongue on the oil net is separated from the socket, and then the pin is separated from the socket, which is convenient for disassembly and assembly. At the same time, the structure of the utility model facilitates the alignment of the tongue with the socket on the socket.

[0031] Preferably, the tongue piece is an elastic piece integrally connected to the side edge of the oil net.

[0032] Compared with the prior art, the advantages of the present invention are: when the oil net needs to be installed, the user can move the oil net upwards so that the tongue on the oil net is inserted into the socket of the socket and is tightened by the limit column to constrain the oil net at the smoke inlet of the shell; conversely, when the oil net needs to be removed, the user can directly move the oil net downwards, and the tongue on the oil net can be detached from the socket, which is easy to operate.

[0033] At the same time, compared with the snap-connection method in the prior art, the oil net of the utility model has a smaller opening and closing force during the disassembly and assembly process, which can prevent oil stains on the oil net from splashing and improve the user experience.

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] like Figures 1 to 7 As shown in FIG. 1 , a preferred embodiment of a mounting structure of an oil screen on a range hood of the utility model is shown. The mounting structure includes a housing 1 , an oil screen 2 and a limiting assembly 3 .

[0043] The side of the housing 1 facing the user is the front side, and the housing 1 has a downward-facing smoke inlet 10. The housing with the smoke inlet 10 is a prior art, and only a part of the housing 1 is shown in the drawings of this embodiment. A socket 11 is provided on the housing 1 adjacent to the rear edge of the smoke inlet 10, and there are at least two sockets 11, which are arranged at intervals in the left-right direction, and each socket 11 is in the shape of a strip extending left-right.

[0044] The oil net 2 is horizontally placed at the smoke inlet 10 of the housing 1. The oil net 2 has a front side and a rear side extending left and right. The front side of the oil net 2 is provided with a tongue piece 20 (elastic piece) extending upward and connected to the oil net 2. There are two tongue pieces 20, one on the left and one on the right. Figure 2 , 3 As shown in FIG. 5 , the rear side of the oil net 2 is provided with pins 23 extending backwards, the number of the pins 23 is consistent with the number of the sockets 11, and each pin 23 is inserted into its corresponding socket 11 and can rotate up and down relative to the socket 11, so that the oil net 2 as a whole can rotate up and down.

[0045] There are two groups of the above-mentioned limiting components 3, one on the left and one on the right, which are arranged at the front edge of the smoke inlet 10 of the housing 1 and are arranged corresponding to the position of each tongue piece 20. Each group of limiting components 3 includes a socket 31, a limiting column 32 and an elastic member 33. The socket 31 is fixed on the housing 1 and has a plug hole 310 extending up and down, and a mounting cavity 312 located at the front side of the plug hole 310, and the tongue piece 20 of the oil supply network 2 of the plug hole 310 is inserted therein. At the same time, the front side wall of the plug hole 310 is provided with a through hole 311 penetrating through the wall thickness to connect the plug hole 310 and the limiting column 32. The above-mentioned limiting column 32 can be constrained in the mounting cavity 312 to move longitudinally, and the head of the limiting column 32 can pass through the through hole 311 and extend into the plug hole 310. The elastic member 33 is a spring extending forward and backward, and is disposed between the limiting column 32 and the side wall of the mounting cavity 312, so that the head of the limiting column 32 always has a tendency to move toward the insertion hole 310 and press the tongue piece 20 tightly into the insertion hole 310. Under the action of external force, the tongue piece 20 can overcome the action of the limiting column 32 and move downward and detach from the socket 31.

[0046] In this embodiment, the middle of the tongue piece 20 is concave to form a groove 21 for the head of the limiting column 32 to be inserted. The bottom wall of the groove 21 extends vertically, and the portion of the rear side wall of the insertion hole 310 opposite to the through hole 311 is a vertical wall. The portion of the tongue piece 20 located above the groove 21 is an arc-shaped body 22 that arches toward the limiting column 32. At the same time, the end face of the head of the limiting column 32 faces backward and has a vertical surface 321 located in the center, a first curved surface 322 extending upward and forward from the upper edge of the vertical surface 321, and a second curved surface 323 extending downward and forward from the lower edge of the vertical surface 321, wherein the vertical surface 321 is used to be inserted into the groove 21 and cooperate with the groove bottom wall of the groove 21; the first curved surface 322 and the second curved surface 323 are symmetrically arranged with the central axis of the limiting column 32 as the center, and the first curved surface 322 is used to contact the upper side wall of the groove 21 in a tangential posture, and the second curved surface 323 is used to contact the lower side wall of the groove 21 in a tangential posture, so as to limit the tongue piece in the up and down directions. For details, please refer to Figure 3 .

[0047] When the oil screen 2 needs to be installed, the user can move the oil screen 2 upwards so that the tongue 20 on the oil screen 2 is inserted into the corresponding socket 310 until the head of the limiting column 32 extends into the groove 21 of the tongue 20. At this time, the head of the limiting column 21 presses the tongue 20 tightly against the socket 310 under the action of the elastic member 33, so that the oil screen can be restrained at the smoke inlet of the shell. For details, please refer to Figures 1 to 3 .

[0048] On the contrary, if Figure 4 , 5As shown, when the oil screen needs to be removed, the user can directly rotate the oil screen 2 downward so that the tongue 20 on the oil screen 2 is disengaged from the socket 31, and then the pin 23 on the oil screen 2 is disengaged from the socket 11 on the shell 1 to remove the oil screen 2, and then perform subsequent operations such as cleaning the oil screen 2.

[0049] 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.
