Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art
[0002] The range hood is installed above the stove, which can quickly extract the waste from stove combustion and the oil smoke generated during cooking that is harmful to the human body and discharge it outdoors. Its working principle is that the internal fan rotates at high speed to form a negative pressure area within a certain space above the stove. The negative pressure sucks the indoor oil smoke gas into the range hood. The oil smoke gas is filtered through the oil net for the first oil smoke separation, and then enters the hood air duct. The oil smoke gas is separated for the second time through the rotation of the impeller. The oil smoke in the wind cabinet is affected by centrifugal force, and the oil mist condenses into oil droplets, which are collected in the oil cup through the oil path. The purified smoke is finally discharged along a fixed passage. The top-side double-suction range hood is a type of range hood. Its main shell is called 7-shaped, and air inlets are set on the vertical and horizontal parts. Smoking in both directions makes the oil smoke extraction more thorough.
[0003] During use, the oil formed by condensation of the main shell will flow along the guide device inside the main body and finally flow into the oil cup at the bottom of the vertical part of the main shell. Since both the vertical and horizontal parts of the conventional top-side double-suction range hood are provided with air inlets, the air inlet of the vertical part is generally designed on the front. In this case, the appearance is complex and the aesthetics is not good. At the same time, the oil can easily drip through the air inlet onto the stove, which makes it difficult to clean.
[0004] Therefore, it is urgent to design a range hood to solve the above-mentioned technical problems. Utility Model Content
[0005] The utility model aims to provide a range hood which can prevent oil stains from the air inlet of the shell from dripping onto the stove, thereby improving the user experience.

[0030] like Figure 1 As shown, this embodiment provides a range hood, which is specifically a top-side double-suction range hood. It includes a shell 10, on which a first air inlet 11 and a second air inlet 12 are provided, the first air inlet 11 is located at the upper part of the shell 10, the second air inlet 12 is located at the bottom of the shell 10, a detachable oil cup 20 is provided at the bottom of the shell 10, and the second air inlet 12 is tilted downward toward the rear side of the shell 10, so that the oil at the second air inlet 12 can flow into the oil cup 20. Optionally, the shell 10 includes a first shell and a second shell arranged up and down, and the first shell and the second shell are connected at a right angle or an obtuse angle. So that the first shell is at least partially located directly above the stove, improving the suction effect of the first air inlet 11.
[0031] The range hood arranges the second air inlet 12 at the bottom of the shell 10, so that the second air inlet 12 is closer to the smoke generating area, thereby effectively improving the smoke extraction effect. At the same time, the second air inlet 12 is arranged at an angle, so that the oil stains at the second air inlet 12 can be smoothly guided to the oil cup 20, solving the problem of oil stains dripping onto the stove due to the air inlet at the bottom of the shell 10, thereby improving the user experience.
[0032] Optionally, the inclination angle of the second air inlet 12 ranges from 30° to 45°. Within this angle range, the oil at the second air inlet 12 can flow smoothly downward into the oil cup 20. Exemplarily, the inclination angle of the second air inlet 12 can be 30°, 35°, 40° or 45°, and the specific angle can be designed according to actual conditions. It should be noted that the inclination angle here refers to the angle between the design plane, i.e., the plane where the second air inlet 12 is located, and the vertical plane.
[0033] In this embodiment, the front side of the oil cup 20 is provided with an avoidance opening, the second air inlet 12 is arranged at the avoidance opening, and the outer surface of the second air inlet 12 is recessed in the outer surface of the avoidance opening. In this embodiment, the oil cup 20 structure is designed to adapt to the second air inlet 12, and an avoidance opening corresponding to the second air inlet 12 is designed on the oil cup 20, and the two are designed in a staggered layer, so that while ensuring that the oil smoke is smoothly sucked away, the oil droplets at the second air inlet 12 can be smoothly connected to the oil cup 20 to avoid contaminating the stove. This structural design realizes the combination of the oil cup 20 and the second air inlet 12, ensuring the simplicity and aesthetics of the front of the product.
[0034] In order to reduce the difficulty of installation and further improve the appearance, the front side of the oil cup 20 is tilted downward toward the rear side of the housing 10, and the tilt angle is not greater than the tilt angle of the second air inlet 12. In this way, the oil cup 20 can be easily and quickly disassembled and assembled, and it can ensure that all the oil droplets at the second air inlet 12 can flow smoothly into the oil cup 20. It should be noted that the tilt angle here refers to the angle between the design surface, i.e., the front side of the oil cup 20, and the vertical surface.
[0035] Optionally, the opening area of the avoidance opening is equal to or slightly larger than the air inlet area of the second air inlet 12, so as to ensure that the second air inlet 12 is not blocked by the oil cup 20, thereby affecting the efficiency of oil fume extraction. In this embodiment, the opening area of the avoidance opening is preferably slightly larger than the air inlet area of the second air inlet 12, further reducing the precision requirement when the oil cup 20 is disassembled and assembled.
[0036] In this embodiment, the air inlet area of the first air inlet 11 is larger than the air inlet area of the second air inlet 12. That is, the first air inlet 11 is the main suction port, and the second air inlet 12 is the auxiliary suction port, which improves the suction efficiency of the range hood. The upper part of the housing 10 is located above the stove, and the first air inlet 11 with a larger area is arranged thereon, which can effectively improve the suction effect. Furthermore, two second air inlets 12 can be provided.
[0037] The range hood further includes a smoke baffle 30, which is movably connected to the housing 10 so that the smoke baffle 30 can open or close the first air inlet 11. When the range hood is turned on, the baffle opens the first air inlet 11 for inhalation, and when the range hood is turned off, the baffle closes the first air inlet 11 to prevent dust and other impurities from adhering.
[0038] Optionally, the top of the smoke shield 30 is rotatably connected to the housing 10 via a rotating shaft. Specifically, a driving mechanism is provided between the smoke shield 30 and the housing 10, and the driving mechanism is used to drive the smoke shield 30 to rotate clockwise or counterclockwise to achieve fixed-axis rotation of the smoke shield 30, thereby achieving the smoke shield 30 to flip and close or open the first air inlet 11. The specific structure of the driving mechanism is not the focus of protection of this embodiment, and any structure that can achieve the above function in the field is acceptable, and will not be described in detail here.
[0039] The oil cup 20 is provided with a detection element ( Figure 1 The detection element is used to detect the liquid level, so as to prompt the user to clean the oil cup 20. Optionally, the detection element is a sensor. When the oil level in the oil cup 20 reaches the detection position, the sensor transmits a signal to the control module of the range hood, and the control module activates a prompt sound to notify the user to clean the oil cup 20. Preferably, the sensor can be a position sensor or a depth sensor, which can be selected according to the needs.
