Description

Oil filter screen can be lifted and hidden range hood

technical field

The invention relates to a kitchen utensil, in particular to a concealed range hood with a liftable oil filter.

Background technique

With the progress of human civilization, in the field of daily-use stoves and range hoods, the shielding, separation and discharge of oil fumes are becoming more and more difficult due to the improvement of the airtightness of modern living rooms and people's requirements for living environments. Among them, the deflector of the range hood is generally fixed on the panel, which not only takes up space in the kitchen, but also the smoking port is always open, which not only affects the appearance of the range hood, especially the range hood that has been used for a long time and has not been cleaned is even more serious. ; In modern urban housing, most of the public exhaust pipes are used, which is easy to cause oil fumes to flow backwards and pollute the indoor air. Chinese Patent No. 20101096655.2 also proposed a range hood with a deflector that can be opened and closed. Its main feature is that the deflector is driven by a motor to drive the transmission to move the entire deflector outward, so that the gap between the deflector and the range hood Separated, the oil fume enters the range hood from the separated gap. However, due to structural limitations, when the deflector is pushed forward as a whole, the thickness of the body will be increased, and the user is easily injured by the pushed out deflector during use. When the oil fume in the kitchen utensils enters the range hood through the deflector, part of the fume or water vapor will easily liquefy on the surface of the deflector to form water droplets or oil droplets after contacting the deflector. At this time, the opened deflector is just above the cooker. , so oil droplets or water droplets are easy to drip into the pot, which is not conducive to food hygiene.

Furthermore, in the existing range hood, no matter whether the deflector of the range hood is a push-forward type or a forward-turning type, since the deflector needs to be movable, it is affected by the structure of the range hood and the internal space layout, so it cannot be installed on the smoking port. Oil filter screen, so when the deflector is opened, the entire smoking port is exposed, which affects the aesthetics of the range hood and gives people an unsafe feeling. Due to the lack of oil filter, the flue gas drawn by the wind wheel directly enters the turbine without any treatment, and the oil fume is separated by the rotation of the turbine, but the separation of oil fume is not complete, and the exhaust pipe is prone to stains. Later, someone tried to install an oil filter on the air inlet of the volute of the fan in an attempt to use the filter to separate the oil fume, but found the following defects during use: 1) Due to the limited area of the air inlet of the volute, after installing the oil filter It will inevitably increase the draft resistance of the turbine, which will easily cause the motor to be overloaded and burnt, and will also generate relatively large noise. 2) The air pressure at the air inlet of the volute is high, and the flow rate of the flue gas is high, so the oil droplets produced by the oil filter screen are immediately sucked away by the fan as soon as they are separated from the flue gas, basically there is no effect of oil fume separation.

Contents of the invention

The object of the present invention is to overcome the above-mentioned defects and provide a concealed range hood with a simple and novel structure, convenient production and processing, beautiful and fashionable appearance, and good oil fume separation effect.

The object of the present invention is achieved in the following manner: a concealed range hood with a liftable oil filter, which includes a main unit, a decorative plate and a deflector are installed on the front end of the main unit, and the deflector is covered on the smoking port. It is characterized in that: the deflector is installed on the linear guide rail in the host, and a motor is installed in the host to drive the deflector to slide up and down relative to the decorative plate, and the deflector is also connected by easy-to-detach bolts. The oil filter can slide up and down, and the oil filter is covered on the smoking port between the deflector and the decorative panel.

The host is provided with a guide groove, and the oil filter screen slides in the guide groove.

The guide groove is formed by bending a plate, and is welded and fixed in the host.

The guide groove is a groove formed by punching inwards of the main body material.

The guide groove is a boss formed by punching out the material of the main body, and a certain distance is set between the front and rear bosses to form a chute for the movement of the oil filter.

The hanging buckle of the deflector is installed on the connecting plate, and the connecting plate is fixedly installed on the linear guide rail.

The oil filter screen is fixed on the connecting plate by easily detachable bolts.

A placement area is opened on the connecting plate, a rack plate with a rack is installed in the placement, and a gear that can cooperate with the rack is installed on the motor.

The inner side of the decorative plate is provided with an oil cleaning brush, and the oil cleaning brush is tightly pressed on the surface of the oil filter net.

The beneficial effects of the invention are: 1) simple structure, low production cost and strong market competitiveness. 2) The panel moves up and down to open and close the smoking port. The opened panel does not occupy the space in front of the range hood. It prevents condensed water and oil droplets from falling into the food, and also prevents users from being injured by the protruding panel. 3) An oil filter is installed on the smoking port to separate the smoke from the smoke and prevent oil pollution from the smoke exhaust port. 4) The oil filter screen can slide up and down with the guide plate, and there is an oil cleaning brush to clean the oil filter screen to keep the oil filter screen clean and hygienic.

Detailed ways

The present invention will be specifically and further described below in conjunction with the accompanying drawings. A concealed range hood with a liftable oil filter, which includes a main unit 1, a decorative plate 11 and a deflector 2 are installed on the front surface of the main unit 1, and the deflector 2 covers the smoking port 21, and is characterized in that: The deflector 2 is installed on the linear guide rail in the host 1, and the host is equipped with a motor to drive the deflector 2 to slide up and down relative to the decorative plate 11, so as to realize the purpose of opening and closing the smoking port. The deflector 2 is also connected with an oil filter 3 that can slide up and down through easily detachable bolts 31 , and the oil filter 3 covers the smoking opening 21 between the deflector 2 and the decorative plate 11 . Wherein the deflector and the oil filter can also be connected in a variety of ways such as material buckle, riveting, welding and so on.

The host 1 is provided with a guide groove 32 , and the oil filter 3 slides in the guide groove 32 .

The guide groove 32 is formed by bending a plate, and is welded and fixed in the host.

The guide groove 32 is a groove formed by punching inwards of the main body material.

The guide groove 32 is a boss formed by punching out the material of the main body, and there is a distance between the front and rear two bosses to form a chute for the movement of the oil filter screen 3 .

The deflector 2 is hooked and installed on the connecting plate 4, and the connecting plate 4 is fixedly installed on the linear guide rail.

The oil filter screen 3 is fixed on the connecting plate 4 by easily detachable bolts (31).

The connecting plate 4 is provided with a placement area, and a rack plate 5 with a rack 6 is installed in the placement, and a gear 61 that can cooperate with the rack is installed on the motor.

The inner side of the decorative plate 11 is provided with an oil cleaning brush, and the oil cleaning brush is tightly pressed on the surface of the oil filter 3 .

Working principle: When in use, turn on the working switch, while the wind wheel rotates, the drive motor drives the deflector to move upwards to open the smoking port. The oil filter has a certain height, so the oil filter can be covered on the smoking port between the deflector and the decorative plate. Since the area of the smoking port is much larger than the air inlet of the fan volute, the present invention uses the larger air inlet area to reduce the wind speed and pressure of the smoke on the oil filter net per unit area, which is beneficial to the flow of the smoke on the oil filter. The net condenses into oil droplets, and flows into the oil collection box along the oil filter net for storage. When the deflector is closed, the oil filter slides down and is hidden behind the decorative panel. In the present invention, because the oil filter screen and the smoking port are misplaced and installed, only when the range hood works and the deflector plate is opened, the oil filter screen covers the smoking port again to separate the smoke from the smoke. It solves the technical problem that the oil filter cannot be installed on the smoking port of the traditional movable deflector range hood. At the same time, each opening and closing movement of the deflector drives the oil filter to move relative to the oil cleaning brush, so that the oil cleaning brush can clean the surface of the oil filter, which is conducive to keeping the oil filter clean and hygienic. It should be noted that the oil filter screen can be arranged on the outer surface or the inner surface of the oil filter screen, and can even be installed on both sides of the oil filter screen.
