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] At present, most of the oil cups on range hoods are long and hollowed out in the middle as oil storage space, which makes the structural strength of the oil cup in the length direction low. When pouring oil from the oil cup, the oil inside the oil cup may form a wave effect due to shaking when flowing in the length direction, causing the oil to move in a concentrated and rapid manner over a large range in the oil cup, increasing the impact force of the oil fluctuation on the oil cup, which may be several times higher than the weight of the oil itself, resulting in increased instability of the oil cup. 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 reduce the influence of oil pollution shaking on 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 a long strip shape as a whole, and its length direction is defined as the left - right direction. The oil cup body has a bottom wall extending in the left - right direction and side walls extending upward from the periphery of the bottom wall. The bottom wall and the side walls jointly define an oil - receiving cavity with an upward - facing opening.

[0009] It is characterized by further comprising:

[0010] A baffle plate, on whose plate surface there are at least two through - holes penetrating the plate thickness and distributed at intervals. The baffle plate is erected in the oil - receiving cavity to divide the oil - receiving cavity into at least two cavities in the left - right direction, and the cavities on both sides of the baffle plate are communicated through the through - holes.

[0011] By arranging the baffle plate with through - holes, the baffle plate does not block the flow of oil stains, and can effectively buffer the fluctuation of the oil stains in the oil cup body, so that the impact force of the oil stains is buffered and released by hitting the baffle plate, avoiding large - range movement and generating a large impact force hitting the oil cup body, thereby improving the stability during the process of taking and placing the oil cup. And setting the baffle plate in the oil cup body can strengthen the structural stability of the oil cup, improve the overall impact resistance of the oil cup, and reduce the risk of oil cup deformation.

[0012] Preferably, the lower side edge of the baffle plate is arranged with concave and convex parts alternating in the extending direction, and the convex parts are supported on the bottom wall of the oil cup body, and the concave parts communicate the cavities on both sides of the baffle plate. In this way, the bottom of the baffle plate does not block the flow of oil stains, ensuring that the oil stains can flow normally in the oil cup body even in the case of a small amount of oil stains, thus not affecting the pouring of the oil cup. At the same time, the structure of the lower edge of the baffle plate with alternating concave and convex parts in the present utility model does not affect the baffle plate being supported in the oil cup body.

[0013] Further, the flow - through area of a single concave part is smaller than the flow - through area of a single through - hole.

[0014] In the above - mentioned scheme, preferably, the side wall on the front side of the oil cup body is inclined forward from bottom to top;

[0015] The front - side edge of the baffle plate has a lower - side part extending forward from bottom to top and an upper - side part extending vertically upward from the upper end of the lower - side part. The lower - side part is attached to the side wall on the front side of the oil cup body, and the upper - side part is spaced relative to the side wall on the front side of the oil cup body to form a notch.

[0016] In this way, when there is too much oil stain in the oil cup body, the oil stain can flow through the notch, thus avoiding the oil stain overflowing from the oil cup body caused by untimely through - hole flow.

[0017] Further, the width of the notch in the front - rear direction is 5 - 10 mm;

[0018] Denote the dimension of the baffle plate in the up - down direction as L, and the depth of the notch in the up - down direction is:

[0019] 1 / 3×L to 1 / 2×L.

[0020] Furthermore, there are at least two of the baffles, which are arranged at intervals in the left - right direction.

[0021] Still further, the number of the baffles is 3 to 6, and the thickness of a single baffle is 1 to 3 mm. Thus, the strength required to buffer the impact force of the oil stain can be ensured, and excessive waste of the baffles can be avoided.

[0022] In each of the above solutions, preferably, an ultrasonic cleaner is further included, which is arranged on the bottom wall of the oil cup body. Thus, the oil stain on the surface of the oil cup can be cleaned by the vibration of the ultrasonic cleaner or the energy generated by the bubble explosion caused by the vibration.

[0023] Preferably, a part of the bottom wall of the oil cup body is concave upward to form a cavity with an open end facing downward for the ultrasonic cleaner to be arranged therein. In this way, the ultrasonic cleaner can be isolated from the oil stain to prevent it from being polluted.

[0024] Still further, the length of the oil cup body is 800 - 1000 mm (specifically, any value between 800 - 1000 mm, such as 800, 900, 1000 mm, etc.), the height is 25 - 50 mm (specifically, any value between 25 - 50 mm, such as 25, 30, 40, 50 mm, etc.), and the width in the front - rear direction is 80 - 100 mm (specifically, any value between 80 - 100 mm, such as 80, 90, 100 mm, etc.);

[0025] The inner diameter of the cavity is 10 - 30 mm, and the inner depth of the cavity is not more than 10 mm.

[0026] Preferably, there are at least two ultrasonic cleaners, which are respectively arranged corresponding to the bottom walls of their respective cavities.

[0027] Preferably, the two side surfaces of the baffle respectively have an N - pole and an S - pole, and a conductor thin plate is arranged in the through - hole. The conductor thin plate is arranged as a part of a closed circuit and can move under the action of the oil stain flowing through the through - hole to cut the magnetic induction line.

[0028] In this way, the kinetic energy of the flowing oil stain can be converted into electric energy.

[0029] Furthermore, the closed circuit is electrically connected to an energy storage device that supplies power to the ultrasonic cleaner. That is, it can provide electric energy for the ultrasonic cleaner.

[0030] In addition, the closed circuit can also be electrically connected to other electrical modules on the range hood, such as a lighting lamp, a sensor, etc. for power supply.

[0031] To ensure that the arrangement of the conductor sheets does not affect the passage of oil stains through the through holes, preferably, there are at least two conductor sheets, which are arranged at intervals along the circumferential direction on the edge of the through hole to expose the central part of the through hole.

[0032] Further, the through hole is hexagonal, and there are three conductor sheets, which are arranged at intervals on three of the six sides of the hexagon. The hexagonal through hole can ensure that there are enough through holes under a limited baffle area and has good structural strength. At the same time, the hexagonal through hole ensures that there is enough gap between the conductor sheets to ensure the flow of oil stains.

[0033] Furthermore, the conductor sheet is trapezoidal, and the lower base of the trapezoid corresponds to one of the sides of the hexagon, the upper base of the trapezoid faces the central part of the through hole, and the included angle between the waist line of the trapezoid and the lower base is 30 - 45°. Denote the side length of one side of the hexagon as M, and the distance between the upper base and the lower base of the trapezoid is 1 / 4×M - 1 / 2×M. This ensures that the conductor sheet can be stably fixed.

[0034] Preferably, denote the thickness of the baffle as S, and the thickness of the conductor sheet is 1 / 4×S - 1 / 2×S.

[0035] The technical solution adopted by the present utility model to solve the above - mentioned second technical problem is: an oil fume extractor, which is characterized by having the oil cup structure as described above.

[0036] Compared with the prior art, the advantages of the present utility model are as follows: by arranging a baffle with through holes, the baffle does not block the flow of oil stains, and can effectively buffer the fluctuation of the oil stains in the oil cup body, so that the impact force of the oil stains is buffered and released by hitting the baffle, avoiding large - range movement and generating a large impact force hitting the oil cup body, thereby improving the stability during the process of taking and placing the oil cup. And by arranging a baffle in the oil cup body, the structural stability of the oil cup can be enhanced, the overall impact resistance of the oil cup can be improved, and the risk of oil cup deformation can be reduced.
