Description

Technical Field

[0001] The invention relates to the field of kitchen appliances, and in particular to an air inlet structure for a range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. With the improvement of living standards, range hoods have gradually become one of the indispensable appliances in people's kitchens. However, most existing range hoods are only provided with a smoke collecting plate, which has a small smoke collecting area and poor smoke collecting effect. Moreover, when the smoke is relatively large, the range hood cannot effectively absorb all the smoke.

[0003] When people use the kitchen, they usually focus on cooking on one side due to habits and environmental influences, and Chinese cuisine is mainly stir-frying. At this time, a large amount of oil smoke is easily generated on one side. Generally, range hoods are symmetrical on the left and right, and the air inlets on the left and right are the same size, so it is impossible to concentrate the absorption on one side.

[0004] Some peers have also conducted research on the left and right air inlets of range hoods. When opening, they are currently mainly opened by rotating. The range hood structure required by this structural principle is limited, and there are certain depth requirements for the smoke collection chamber and space. Summary of the invention

[0005] In order to overcome the above defects, the present invention provides a range hood air inlet adjustment device, which can absorb oil smoke in a targeted manner, effectively improve the oil smoke absorption efficiency and can be applied to European-style and thin range hoods.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a range hood air inlet adjustment device, including a body, a smoke collecting chamber and an oil cup, a smoke inlet is provided on the top of the smoke collecting chamber, a movable smoke baffle and a smoke sensing control module are provided, the movable smoke baffle is in the smoke collecting chamber, the movable smoke baffle is below the smoke inlet, based on the use direction, the movable smoke baffle can move freely left and right in the smoke collecting chamber, and the downward projection of the smoke inlet is always on the movable smoke baffle, and the smoke sensing control module controls the movement of the movable smoke baffle. (The smoke sensing control module controls the left and right movement of the movable smoke baffle according to the amount of smoke detected at the left and right burners. If the amount of smoke on the left side is large, the movable smoke baffle is controlled to move to the right.)

[0007] A further technical solution of the present invention is that an oil net group is provided on the oil fume inlet.

[0008] A further technical solution of the present invention is: the structure in which the movable smoke baffle can move freely left and right in the smoke collecting chamber is: a slide groove and a driving device are provided, the slide groove and the driving device are arranged in parallel, and a first and a second connecting bracket are provided. Based on the use direction, the second connecting bracket can move left and right in the slide groove, and the driving device includes a slider, a screw rod and a motor. The power of the motor is output to the screw rod, and the slider is movably sleeved on the screw rod through a thread. The first connecting bracket is positioned on the slider, and the movable smoke baffle is positioned on the first and the second connecting brackets. The oil fume sensing control module controls the forward and reverse rotation of the motor. In this way, the screw rod is driven by the motor to rotate, so that the slider moves left and right on the screw rod, thereby moving the first connecting bracket left and right, and finally realizing the movable smoke baffle to move freely left and right in the smoke collecting chamber, that is, the air inlet on one side is significantly enlarged, and the negative pressure is significantly enhanced at this time, which can effectively improve the oil fume suction efficiency on one side. There are many similar principle structures, which are similar technologies, and this example will not give examples one by one.

[0009] A further technical solution of the present invention is: the movable smoke baffle is high on all sides and low in the middle to form a bottom, and the cross-section is a concave arc. The inner concave shape can guide oil stains, and an oil cup (for receiving accumulated oil stains) is installed at the bottom of the movable smoke baffle.

[0010] A further technical solution of the present invention is: the movable smoke shield is hung on the first and second connecting brackets through four hooks, and the first and second connecting brackets are both inverted T-shaped, so that when the movable smoke shield needs to be disassembled, the movable smoke shield can be lifted up and removed, which is convenient for disassembly.

[0011] A further technical solution of the present invention is: the oil cup has a trapezoidal cross-section, an oil guide column is provided in the middle, the upper end of the oil guide column has a thread inside, the middle of the oil guide column is a hollow structure, the bottom wall of the oil guide column has a side oil leakage hole, the bottom of the movable baffle is provided with a drainage column, the outer side of the drainage column is provided with a thread, the middle of the drainage column is a hollow structure, the oil cup oil guide column is locked on the drainage column by a thread, so that the oil is gathered through the smoke baffle and drained into the oil cup through the hollow structure in the middle of the drainage column and the side oil leakage hole.

[0012] The beneficial effects of the present invention are as follows: since the movable smoke baffle is located below the oil fume inlet, the movable smoke baffle can move freely left and right in the smoke collecting chamber. The structure of the present invention is a horizontal operation mode of the left and right switchable air inlets, so it can be introduced and used on European-style and thin range hoods, and the oil fume sensing control module can control the left and right movement of the movable smoke baffle. The oil fume sensing control module controls the left and right movement amount of the movable smoke baffle according to the detected oil fume amount at the left and right burners. In this way, it can be adjusted according to the actual situation of the oil fume, improve the smoke collection effect of the range hood, and effectively improve the smoking efficiency.
