Description

Technical Field

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

[0002] Existing range hoods generally include a range hood body and an oil cup disposed below the range hood body. The oil cup is used to collect the oil in the range hood body, and the user needs to remove the oil cup to dump the oil. Specifically, the Chinese utility model patent "An oil cup installation structure for a range hood" with application number CN201821055443.0 (authorization announcement number CN208579370U) includes a housing and an oil cup. The oil cup is detachably disposed at the bottom of the housing through an installation assembly. The installation assembly includes a first positioning block, a second positioning block and an elastic member. The first positioning block is disposed at the bottom of the housing and has a first positioning portion at the lower end; the second positioning block is disposed on the inner wall of the oil cup and has a second positioning portion at the upper end; the elastic member enables the second positioning portion to always maintain a tendency to engage with the first positioning portion.

[0003] Another example is the Chinese utility model patent "A Range Hood" with application number CN201821529177.0 (authorization announcement is CN209026905U), which includes a shell and an oil cup. At least two slots extending in the front-to-back direction are arranged at intervals at the bottom of the shell. The oil cup is in the shape of a long strip and is installed at the bottom of the shell and extends in the left-to-right direction. The oil cup has a corresponding plug-in extending in the front-to-back direction and is plugged into the slot; the plug-in is located at a position with a certain distance from the left and right ends of the oil cup and is higher than the upper edge of the rear side of the oil cup.

[0004] Currently, the oil cups on range hoods are mostly long and hollowed out in the middle as a storage space for oil. However, since the wall of the oil cup is flat and has weak torsion resistance, the oil cup is easily deformed and damaged if it falls and is subjected to force. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide an oil cup structure for a range hood in view of the current status of the prior art, so as to improve the structural strength.

[0006] The second technical problem to be solved by the utility model is to provide a range hood with the above oil cup structure.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: an oil cup structure for a range hood, comprising:

[0008] The oil cup body is in the shape of a long strip as a whole, and its length direction is the left-right direction, and the oil cup body has a concave cavity with an opening facing upward;

[0009] Features:

[0010] The bottom surface of the concave cavity is a curved surface which is low at the left and right ends and high in the middle and arches upward.

[0011] The curved surface with low left and right ends and high center and arching upward enables the oil cup body to bear heavy oil in the length direction and remain stable; and after the oil falls from the opening, it will flow to the left and right sides of the concave cavity to store oil under the action of its own gravity, ensuring a certain amount of oil storage, and the oil storage on the left and right sides is more than that in the center. When the user tilts the oil cup to pour the oil, his hands are just located on the left and right sides of the oil cup body, which is convenient for holding the oil cup.

[0012] In order to further improve the structural strength, preferably, the bottom surface of the cavity is simultaneously in an arc-shaped structure with high front and rear ends and a low middle portion.

[0013] Preferably, the oil cup body includes a main wall extending left and right and end walls located at the left and right ends of the main wall, the two end walls and the main wall together form the concave cavity with the opening facing upward, and the main wall is a structure formed by a curve rotating around a central axis extending left and right, the left and right ends of the curve are relatively far away from the central axis, and the center of the curve is relatively close to the central axis.

[0014] Furthermore, the main wall is a catenary surface formed by rotating the curve 180° around the central axis, and the end wall is a corresponding semicircular structure. The catenary surface structure has the following advantages: 1. The oil cup has good strength; 2. The bottom and side surfaces of the oil cup are beautiful in shape, and the two-handed holding feeling is good and conforms to the user's oil cup holding gesture; 3. The oil cup has a large oil storage capacity and is stable; 4. The bottom of the oil cup is a curved surface and cannot be placed on a flat surface, reminding the user to install the oil cup as soon as possible after pouring the oil to avoid forgetting.

[0015] Preferably, the angle between the tangent of the catenary surface and the end wall is 45-85°. In this way, the angle coincides with the angle range between the fingers and the palm of the user when holding the oil cup, which is convenient for the user to hold.

[0016] Preferably, the end wall is arranged vertically or inclined.

[0017] Furthermore, the upper edge of the end wall is provided with a hanging ear extending horizontally inwards.

[0018] In the above-mentioned solutions, preferably, the height difference between the high point and the low point of the curved surface is 10 to 50 mm.

[0019] Preferably, the opening edge of the oil cup body is arranged horizontally.

[0020] The technical solution adopted by the utility model to solve the second technical problem is: a range hood, characterized by having the oil cup structure as described above.

[0021] Compared with the prior art, the advantages of the utility model are: the curved surface with low left and right ends and high center and arching upward enables the oil cup body to bear a large weight of oil in the length direction and remain stable; and after the oil falls from the opening, it will flow to the left and right sides of the concave cavity to store oil under the action of its own gravity, ensuring a certain amount of oil storage, and the oil storage amount on the left and right sides is more than that in the center. When the user tilts the oil cup to pour the oil, his hands are just located on the left and right sides of the oil cup body, which is convenient for holding the oil cup.
