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 have a hollowed-out middle portion 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 strength of the oil cup.

[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 wall of the cavity is a first curved surface with a lower center and higher left and right ends in the length direction, and a second curved surface with a higher center and lower front and rear ends in the width direction.

[0011] In this way, the shape of the bottom wall of the concave cavity formed by the first curved surface and the second curved surface can resist compression and stretching, ensure strength, so that the oil cup body can be loaded with more oil and is not easily deformed and damaged after falling or colliding; and the bottom wall of the concave cavity is a curved surface shape 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.

[0012] Preferably, the first curved surface is a parabola, and the second curved surface is a parabola, that is, the bottom wall of the cavity is in the shape of a hyperbolic parabola.

[0013] Preferably, the concave cavity of the oil cup body is in a structure with a larger upper end and a smaller lower end, so that the oil flowing down from the smoking machine body can be better received and the oil can be poured out more easily.

[0014] Preferably, the front side wall of the concave cavity has a first inclined portion extending upward and forward from the front side edge of the bottom wall; the rear side wall of the concave cavity has a second inclined portion extending upward and backward from the rear side edge of the bottom wall. The first and second inclined portions facilitate the user's fingers to grip the oil cup when pouring oil, making it easier to pour oil.

[0015] Furthermore, the front side wall of the cavity also has a first vertical portion extending vertically upward from the upper side of the first inclined portion, and the rear side wall of the cavity also has a second vertical portion extending vertically upward from the upper side of the second inclined portion, so that the oil cup of the utility model has a larger oil storage capacity.

[0016] In order to further improve the structural strength, preferably, the shape of the upper side of the first inclined portion is consistent with the shape of the front side of the bottom wall; the shape of the upper side of the second inclined portion is consistent with the shape of the rear side of the bottom wall. The shapes of the upper side of the first inclined portion and the upper side of the second inclined portion are both curved, and the two curves play the role of a skeleton in strengthening the overall strength of the entire oil cup body.

[0017] Preferably, the upper edge of the first vertical portion and the upper edge of the second vertical portion are both straight edges extending left and right. The straight edges can remain parallel to the oil plane to ensure that there is no oil leakage. It is also beneficial for the gap between the oil cup and the range hood body to be uniform after the oil cup is installed.

[0018] Furthermore, the upwardly extending height of the first inclined portion and the second inclined portion is 50 to 80 mm.

[0019] In the above schemes, preferably, the left and right side walls of the cavity both extend vertically upward.

[0020] Preferably, upper edges of the left and right side walls of the cavity are provided with hanging ears extending horizontally inwards.

[0021] 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.

[0022] Compared with the prior art, the advantages of the utility model are: the shape of the bottom wall of the concave cavity formed by the first curved surface and the second curved surface can resist compression and stretching, ensure strength, so that the oil cup body can be loaded with more oil and is not easily deformed and damaged after falling or colliding; and the bottom wall of the concave cavity is a curved surface shape 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.
