Problems solved by technology

However, most of the existing range hoods, no matter they are top-suction or side-suction, use exposed range hoods, and the oily residual liquid that sticks to them leaks out as a whole, which makes people feel unhygienic and affects users. And there is no baffle device, the user can only judge whether the suction port has been cleaned by vision, which affects the user's perception, and it is easy to forget to clean it and cause the oil to stick to the suction port to block the suction port, thereby greatly reducing the wind of the fan pressure, kitchen fumes can not be better controlled the diffusion of fumes and heat except forced suction out

Embodiment 1

[0020] see figure 1 , the present invention provides a technical solution: as figure 1 The shown range hood oil tank device includes a box body 3, lifting lug 9, and oil tank 10; the lifting lug 9 is fixed on the box body 3 with a nut 7 at a height of 1.5 mm, and the oil tank 10 is at a height of 1.5 mm Sliding between the gaps is convenient for subsequent maintenance and cleaning, and overcomes the previous problem of difficult cleaning; the oil receiving tank 10 is designed with a transparent window, so that the storage status of oil stains can be watched at any time to achieve timely cleaning.

Embodiment 2

[0022] see figure 2 , the present invention provides a technical solution: as figure 2 The range hood baffle device shown includes a box body 3, a stepping motor 4, a nut 7, and a windshield 8; When working, you only need to push the windshield 8 in the opposite direction by hand, and at this time the air suction port 1 on the box body 3 is blocked, which can effectively prevent dust and mosquitoes from entering when not in use; the upgraded version of this device, When we don't use the oil fume equipment, we can press the button on the infrared remote control 13 or touch the button. At this time, the stepper motor 4 will close the suction port 1 instantly after receiving the instruction, which can effectively prevent dust and mosquitoes from entering when not in use. It shows a higher technological content.

Embodiment 3

[0024] see image 3 , the present invention provides a technical solution: as image 3 The air filling device for the range hood shown includes a fresh air outlet 1, an air plate 5, and an air pipe 6; the upper end of the air plate 5 is provided with a 45° deflector groove; when we are cooking, an air curtain will be formed on it, At this time, through the 45° deflector on the top of the wind plate, the fresh air curtain is instantly diffused to form a wind screen, which can effectively prevent the cooking fume and heat from spreading.

Abstract

Provided is an extractor hood, comprising exhaust inlets (1) having baffle plates, a negative-pressure fan (2), a box body (3), a fresh air channel, a fresh air chamber (17), an air-out groove (18), a stepping electric motor (4), an air board (5), an air pipe (6), nuts (7), lifting lugs (9), an oil receiving groove (10), a soft plastic hose (11) and a control part (12). The box body (3) is linked to the oil receiving groove (10). The box body (3) is provided with the alternately staggered exhaust inlets (1). An air-deflector baffle (8) is provided on a back side of the box body (3). The air deflector baffle (8) and a threaded rod (14) are closely linked together and are fixed through hole sites on the box body (3). The air deflector baffle (8) is connected to the stepping electric motor (4). The negative-pressure fan (2) and an automatic cleaning device (15) are fixedly provided inside the box body (3). The soft plastic hose (11) is connected to an upper end of the negative-pressure fan (2). The lifting lugs (9) are fixed onto the box body (3) by means of the nuts (7). The bottom of the fresh air chamber (17) is provided with the air-out groove (18). Fresh air at a certain pressure enters the fresh air chamber (17) via an fresh air port (16) through the pipe and generates three air screens in the air-out groove (18), and thus fumes controlled by the air screens and the fresh air are extracted together by the negative-pressure fan (2) and discharged outdoors. Since the air deflector baffle (8) is added at the exhaust inlets (1), backward flow of the fumes and dust can be prevented.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, specifically a range hood, which is equipped with an automatic cleaning device, and the equipment can be cleaned and maintained regularly to a certain extent; the air suction port is provided with a movable baffle, which can be closed when the equipment is closed The baffle prevents the entry of dust and mosquitoes, and also prevents the oil fume from flowing back. Fresh air barrier function, the air intake passes through the wind screen barrier generated by the air guide groove on the fan plate to control the diffusion of oily smoke and more effectively control the diffusion of heat in the kitchen. Background technique [0002] The existing range hoods mainly have two working modes: top suction type and side suction type. The characteristics of clean and tidy atmosphere; side suction range hood is also called near range hood, its installation position is closer to the stove, and it can...
