Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a mounting structure of an oil net on a range hood and the 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 not removable, and its outer surface can only be scrubbed during cleaning, which may cause it to not be scrubbed 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 connections through magnetic suction structures, such as the Chinese utility model patent "A range hood with an oil filter net having a magnetic adsorption fixed installation" with patent number 202121428669.2 and authorization announcement number CN215832006U, which includes a 7-shaped fuselage, the 7-shaped fuselage includes an upper fuselage located at the top and having a top suction smoke collection chamber, and a lower fuselage located at the bottom and having a side suction smoke collection chamber, the top suction smoke collection chamber is provided with an upper air inlet, the side suction smoke collection chamber is provided with a side air inlet, and the side air inlet is covered with an oil filter net, and a hanging plate is provided at the bottom of the back of the oil filter net, which is hung at the bottom of the side air inlet, and a magnetic suction device is provided at the top of the back of the oil filter net, which is adsorbed and fixed on the side air inlet.
[0004] Magnetic devices mostly use permanent magnets to attract oil nets. Different users have different requirements for magnetic attraction force, so the disassembly and assembly experience is also different. The same permanent magnet is difficult to meet the disassembly and assembly experience of different users. Utility Model Content
[0005] The first 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 that the oil net can be stably constrained on the range hood and can be disassembled and assembled with relatively little effort.
[0006] The second technical problem to be solved by the utility model is to provide a range hood with the above-mentioned installation structure.
[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a mounting structure of an oil screen on a range hood, comprising:
[0008] The range hood body has a smoke inlet;
[0009] A magnetic member, arranged on the range hood body;
[0010] An oil net is located at the smoke inlet of the range hood body and is attracted to the magnetic member so that the oil net can be fixed relative to the range hood body;
[0011] Features:
[0012] The magnetic member is movably arranged and can be moved to a position relatively far away from the oil net to reduce the suction force on the oil net, thereby enabling the oil net to be removed from the smoke inlet.
[0013] In this way, when the oil net needs to be removed, the magnetic part can be moved away from the oil net to reduce the suction force on the oil net, so that the oil net can be removed more easily and with less effort; when installing the oil net, the magnetic part can be moved close to the oil net and attracted to the oil net, so that the oil net can be stably constrained at the smoke inlet of the range hood body.
[0014] Preferably, the magnetic member is a bar magnet, which can move to an attracted state in which the first end of the bar magnet is relatively close to the oil net and attracted to the oil net, and to a desorbed state in which the first end of the bar magnet is relatively far away from the oil net.
[0015] Preferably, the smoke inlet is located on the front side wall of the range hood body;
[0016] The bar magnet is arranged on the front side wall of the range hood body and at the periphery of the smoke inlet in a manner that it can rotate around its center, and in the attracted state, the extension direction of the bar magnet intersects with the extension direction of the corresponding edge of the smoke inlet, and the first end of the bar magnet extends toward the edge of the smoke inlet and is attracted to the edge of the oil net; in the desorbed state, the extension direction of the bar magnet is parallel to the extension direction of the corresponding edge of the smoke inlet. The above-mentioned "parallel" means substantially parallel, and is not limited to completely parallel.
[0017] Preferably, the range hood body is further provided with two magnetic insulation sheets, which are respectively provided on both sides of the bar magnet and are respectively opposite to the two ends of the bar magnet in the desorption state. The provision of the magnetic insulation sheets can further reduce the magnetic attraction of the bar magnet to the oil net in the desorption state.
[0018] Furthermore, the first end of the bar magnet is referred to as the N pole, and the second end is referred to as the S pole;
[0019] It also includes a permanent magnet, which is fixed relative to the range hood body, and the N-pole portion of the permanent magnet is opposite to and attracted to the second end of the bar magnet in the attracted state. The arrangement of the permanent magnet enables the bar magnet to be maintained in the attracted state. In addition, if the user does not completely rotate the bar magnet to the attracted state, resulting in insufficient suction force of the bar magnet on the oil net and causing the oil net to fall off, the arrangement of the permanent magnet in the utility model can attract the second end of the bar magnet to align with it, ensuring that the bar magnet is in the attracted state.
[0020] Furthermore, the magnetic attraction between the N-pole part of the permanent magnet and the second end of the bar magnet is 10-30 N. The magnetic attraction meets the daily adsorption requirements of the oil net, and the magnetic attraction does not cause difficulty in disassembly.
[0021] Furthermore, the bar magnet is arranged above the smoke inlet, and in the attracted state, the bar magnet extends up and down; in the desorbed state, the bar magnet extends left and right; the two magnetic-insulating sheets are arranged on the left and right sides of the bar magnet, and the permanent magnet is arranged above the bar magnet.
[0022] In the above schemes, preferably, the bar magnet is arranged on the rear side of the front side wall of the range hood body;
[0023] The range hood also includes a knob, which is arranged on the front side of the front side wall of the range hood body and is bound together with the bar magnet. Thus, the bar magnet can be driven to rotate by rotating the knob.
[0024] Preferably, a protective cover is further included, which is arranged at the rear side of the front side wall of the range hood body, and has a peripheral wall which is located at the periphery of the bar magnet in the circumferential direction and extends forward and backward, the rear side edge of the peripheral wall is joined to form a closed end face, and the front side edge of the peripheral wall is in contact with the front side wall of the range hood body;
[0025] The two magnetic-insulating sheets and the permanent magnet are all arranged on the peripheral wall, thereby preventing the influence of oil smoke on the bar magnet, the magnetic-insulating sheets and the permanent magnet.
[0026] The technical solution adopted by the utility model to solve the second technical problem is: a range hood, characterized by having the installation structure as described above.
[0027] Compared with the prior art, the advantages of the utility model are: when the oil net needs to be removed, the magnetic part can be moved away from the oil net to reduce the suction force on the oil net, so that the oil net can be removed more easily and with less effort; when installing the oil net, the magnetic part can be moved close to the oil net and attracted to the oil net, so that the oil net can be stably constrained at the smoke inlet of the range hood body.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] like Figures 1 to 5 As shown, a mounting structure of an oil screen on a range hood and a preferred embodiment of the range hood of the utility model are shown, and the mounting structure includes a range hood body 1, a magnetic part 2, an oil screen 3, a magnetic insulating sheet 4, a permanent magnet 5, a knob 6 and a protective cover 7.
[0035] The front side wall 11 of the range hood body 1 is provided with a smoke inlet 10 penetrating through the wall thickness. The portion of the front side wall 11 of the range hood body 1 located above the smoke inlet 10 is recessed backward to form a cavity 110, which has a circular rear side wall 111, a ring wall 112 extending forward from the periphery of the rear side wall 111, and a through hole 113 is provided in the center of the rear side wall 111.
[0036] The oil net 3 is arranged at the smoke inlet 10 of the range hood body 1 .
[0037] The knob 6 is disposed in the cavity 110;
[0038] The magnetic member 2 is a bar magnet and is disposed at the rear side of the rear side wall 111 of the cavity 110. The center of the magnetic member 2 is connected to the knob 6 via a rotating shaft 61, which is inserted into the through hole 113 of the rear side wall 111. Thus, the knob 6 and the magnetic member 2 can rotate around the central axis of the rotating shaft 61. The magnetic member 2 can rotate to:
[0039] In the state of being attracted and extending up and down, at this time, the first end (i.e., the lower end) of the bar magnet is the N end, and is close to the oil net 3 and attracted to the edge of the oil net 3, so that the oil net 3 can be fixed relative to the range hood body 1; the second end (i.e., the upper end) of the bar magnet is the S end;
[0040] In the desorption state extending left and right, both ends of the bar magnet are relatively far away from the oil net 3 to reduce the suction force on the oil net 3, so that the oil net 3 can be removed from the smoke inlet 10.
[0041] The protective cover 7 is arranged at the rear side of the front side wall 11 of the range hood body 1, and has a peripheral wall 71 which is circumferentially located at the periphery of the bar magnet and extends forward and backward. The rear edge of the peripheral wall 71 is joined to form a closed end surface 72. The front edge of the peripheral wall 71 is located at the periphery of the ring wall 112 of the concave cavity 110 and is in contact with the front side wall 11 of the range hood body 1 to surround the magnetic member 2.
[0042] The above-mentioned magnetic-insulating sheet 4 and permanent magnet 5 are both arranged in the protective cover 7, and there are two magnetic-insulating sheets 4 made of brass, which are arranged on the peripheral wall 71 of the protective cover 7, one on the left and one on the right, and are respectively opposite to the two ends of the bar magnet in the desorption state, so as to further reduce the magnetic attraction of the bar magnet to the oil net. The above-mentioned permanent magnet is arranged at the top of the peripheral wall 71 of the protective cover 7, and the N-pole part of the permanent magnet 5 is opposite to and attracted to the second end of the bar magnet in the attraction state, and the magnetic attraction of the two is 10 to 30N (the magnetic attraction can be any value between 10 and 30N, such as 10N, 15N, 30N, etc.).
[0043] In this way, when the user needs to remove the oil net 3, the knob 6 needs to be rotated to a horizontal position, so that the bar magnet is also in a horizontal position. The strongest magnetic fields generated at the N and S extremes of the bar magnet are completely shielded by the magnetic insulating sheet 4, and the weakest part of the middle magnetic field of the bar magnet is aligned with the oil net. Therefore, at this time, the suction force of the bar magnet on the oil net 3 is very small and can be ignored, and the user can easily remove the oil net.
[0044] When the user needs to assemble the oil net 3, the knob 6 needs to be rotated to the vertical direction. At this time, the N and S ends of the bar magnet generate the strongest magnetic field to align with the oil net, so the bar magnet has the greatest suction force on the oil net 3, and the user can easily assemble the oil net. In order to prevent the user from not rotating the knob 6 accurately to the vertical position, which makes the bar magnet have insufficient suction force on the oil net 3 and causes the oil net 3 to fall, a permanent magnet 5 is arranged in the protective cover 7. The N pole part of the permanent magnet 5 can attract the S pole of the bar magnet to always remain at the top vertically, and the N pole is located at the bottom to absorb the oil net, so as to ensure that the oil net 3 is stably constrained on the range hood body 1 and will not fall.
[0045] 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.
[0046] The term "vertical" is also used in the specification and claims of the present utility model, which means basically along the up and down direction, and is not limited to the vertical direction only, and can also be slightly inclined relative to the vertical direction.
[0047] The term "radial" is also used in the specification and claims of the present utility model, which means basically along the inward and outward direction, and is not limited to the radial direction passing through the center of the circle, and can also be slightly deviated from the radial direction.
