Description

Slide cover linkage magnetically controlled energy-saving range hood

technical field

The patent of the present invention relates to a cooker fume exhaust device, in particular to a sliding cover linkage magnetically controlled energy-saving range hood.

Background technique

With the deterioration of the earth's environment and energy shortage, energy conservation and emission reduction has become an important issue that human beings must pay attention to and advocate.

At present, the range hoods used in domestic household kitchen stoves generally cannot adjust the size of the gap in front of the stove. As long as the stove is ignited, whether it is fast frying with a strong fire, slow cooking on a medium fire, steaming and boiling on a low fire for a long time, or slow fire and stewing for several hours, the fan must be turned on. Get rid of oil fume and exhaust gas. In order to save electricity, or can’t bear the noise of the fan for a long time, some users mistakenly think that it is unnecessary to turn on the exhaust fume when they cook on low heat for a long time, or cook slowly at a slow fire for several hours without producing oily fumes from frying and cooking. Turn off the fan, but at this time, the harmful gas after burning will cause far more harm to the human body than the volatile oil fume in the pot will cause to the human body.

Although some have taken measures to shield the front of the furnace, they have not solved the problem of oil fume exhaust when the electricity is not used. Although some have solved the problem of not using electricity to exhaust oil fume under the special conditions of strong suction and high exhaust flue by taking measures to shield the front of the furnace, they have not solved the problem of not having strong suction and high exhaust flue. The problem of oil fume exhaust when cooking in a large operating space.

The working principle of the present invention is as follows:

Using the patented cooking of the present invention to exhaust fume and exhaust gas, when using the cooking pot (4) to cook for a long time, or cook slowly for several hours, or when personnel are not required to stir fry in the pot or other operations, the operator can turn off the Power off, the range hood (7) stops working, and the dustproof blade (24) is closed. Pull the handle (43) downward, the bottom of the weight-lifting transparent sliding cover (6) and the guide wheel A (40) are tilted up, the sliding cover sealing strip (37) is separated from the slideway (16), and the guide wheel B ( 41) and the upper traveling wheel (35) are in contact with the slideway (16), continue to pull the handle (43) downward, and the counterweight lifting transparent sliding cover (6) can slide down along the slideway (16) to Lower, so that the neutral gear in front of the furnace is adjusted to a smaller state. When the counterweight lifting type transparent sliding cover (6) slides down, the sliding counterweight (39) is lifted up by the pulley rope B (38) and the counterweight pulley (18), and at the same time, the sliding cover counterweight (39) drives the The counterweight (31) of the swing arm (31) is lifted upwards, the pulley rope A (30) is in a slack state, the swing arm (28) swings from the bottom to the top with the magnet (26), and due to the effect of the magnetic force, the magnetic part (27 ) drives the dust-proof blade (24) to swing from the closed state below to the open state above along with the magnet (26), so that the oil fume exhaust gas can be smoothly discharged to the outside.

When cooking with a frying pan (3) or when a small action is required on the top of the stove (1), you can operate the fan outlet control switch (21) to turn the range hood (7) to a low-power operation, and pull the handle upwards (43), the bottom of the counterweight lifting transparent sliding cover (6) and the guide wheel B (41) are tilted, the sliding cover sealing strip (37) is separated from the slideway (16), and the guide wheel A (40) and the upper travel The wheel (35) is in contact with the slideway (16), and the handle (43) continues to be pulled upward, and the weight-lifting transparent sliding cover (6) can be slid upwards to the middle position along the slideway (16), so that the front of the furnace is in neutral position. Adjust to a moderate state. When the counterweight lifting type transparent slide cover (6) slides up, the slide cover counterweight (39) is lifted up by the pulley rope B (38) and the slide cover counterweight pulley (18), and meanwhile, the slide cover counterweight (39 ) descends downward, and the swing arm counterweight (31) above it also descends downward thereupon, and the swing arm counterweight (31) makes the swing arm counterweight (31) make the swing arm counterweight pulley (29) The swing arm (28) swings from the top to the bottom with the magnet (26). Due to the wind force of the range hood (7), the dustproof blade (24) can still be kept in the open state, so that the exhaust gas can be smoothly discharged to the outside. . Middle frame front end sealing strip (15) and sliding cover sealing strip (37) can make the top and both sides sealing of counterweight lifting formula transparent sliding cover (6), can make oil fume waste gas can not leak into the room.

When cooking with a frying pan (3) or when it is necessary to perform a large action on the top of the stove (1), you can manipulate the fan outlet control switch (21) to turn the range hood (7) to high-power operation, and pull the handle upwards (43), the bottom of the counterweight lifting transparent sliding cover (6) and the guide wheel B (41) are tilted, the sliding cover sealing strip (37) is separated from the slideway (16), and the guide wheel A (40) and the upper travel The wheel (35) is in contact with the slideway (16), and the handle (43) continues to be pulled upwards, and the counterweight-lifting transparent sliding cover (6) can be slid upwards to the upper position along the slideway (16), so that the air conditioner in front of the furnace can be adjusted. to a larger state. Due to the wind effect of the range hood (7), the dust-proof blade (24) can still be kept in the open state, so that the exhaust gas of the range hood can be smoothly discharged to the outside.

After cooking, turn off the power supply of the range hood (7), keep the counterweight lifting transparent sliding cover (6) in the upper position, or slide from the lower position to the upper position, and use the sliding cover counterweight (39) and swing arm to match The linkage of weight (31), swing arm (28), magnet (26), magnetized part (27) and dust-proof blade (24) seals the exhaust duct to prevent dust, mosquitoes and rodents from entering the exhaust duct. Go indoors.

The invention patent makes the operation very light and convenient through counterweight, linkage and magnetic control design. Under the condition of having or not having strong suction and high flue exhaust, and under the premise of completely removing the fumes and waste gas, according to the characteristics and needs of various cooking methods, the size of the gap in front of the stove can be adjusted at will, and the fan power can be adjusted accordingly size or turn off the fan. When cooking without operation, turn down the neutral gear in front of the furnace, turn off the fan and keep the dust-proof blades open to exhaust smoke. After use, the dust-proof blades can also be closed to be in a dust-proof, mosquito-proof and rodent-proof state.

In the event of a power outage or motor failure, try to adopt a cooking method that does not require a long time to increase the neutral position above the stove, so as to minimize the emission of oily fume and exhaust gas into the room. Even when there is no power outage and the motor is in good condition, if you want to save electricity costs and minimize the discharge of oil fume and exhaust gas into the room, you should try your best to adopt a cooking method that does not require a long time to increase the neutral gear above the stove to save electricity. , No noise and environmental protection effect.
