Description

Range hood with self-controlled opening and closing of deflector

technical field

The utility model relates to a range hood, in particular to a range hood with a guide plate that can be opened and closed automatically.

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. The range hood is separated, and the oil fume enters the range hood from the separated gap. However, due to structural limitations, the overall load bearing of the deflector is on the transmission device, and the movement of the transmission device requires a large amount of power. Moreover, the working environment inside the range hood is harsh, and the oil fume is likely to cause the transmission device to rust and lock. If the deflector is pushed out forcibly, it is easy to cause damage to the deflector. In addition, its structure is limited by the side-drawing type, and the range hood is easy to escape upwards, resulting in disadvantages such as unclean removal of the lampblack.

Utility model content

In order to solve the above problems, the utility model provides a range hood which is simple in structure, easy to use, the deflector can be opened and closed by automatic control, and the oil fume is sucked clean.

The purpose of this utility model is achieved in the following ways.

A range hood with self-controllable opening and closing of deflectors is composed of a range hood body, an oil collection box arranged on the range hood body, a smoke collection chamber, a panel and a control box arranged on the panel, and a movable guide is installed on the panel. The flow plate is characterized in that: the range hood body is provided with a rack gear to connect with the movable deflector, one end of the deflector is movably connected with the range hood body through a movable hinge, and the range hood body is provided with a positive The motor is reversed, and the motor drives the rack gear through the gear to open and close the movable deflector.

The gear transmission device is composed of an arc-shaped rack and a motor capable of forward and reverse rotation. The arc-shaped rack is provided with a support groove, and a fixed shaft passes through the support groove and is fixed on the support base.

There is also a travel switch on the support seat, and the switch contacts of the travel are arranged on the arc-shaped rack

The forward and reverse motor and travel switch are electrically connected with the control box.

The gear transmission device is installed in the center of the range hood body, and the arc-shaped rack is movably hinged to the hinge seat in the center of the movable baffle.

The beneficial effects of the utility model are: simple structure, convenient use, self-controlled opening or closing of the deflector, beautiful appearance, prevention of backflow of oil fume, smooth smoking of the range hood, clean oil fume suction and the like.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in the figure: a range hood with self-controllable opening and closing of deflector plate, which consists of range hood body 5, oil collection box 4 arranged on range hood body 5, smoke collection chamber 8, panel 1 and panel 1 The control box consists of a movable deflector 3 installed on the panel 1, which is characterized in that: the range hood body 5 is provided with a rack drive to connect with the movable deflector 3, and one end of the deflector 3 is moved through The hinge 2 is movably connected with the range hood body 5, and the range hood body 5 is provided with a motor 67 capable of forward and reverse rotation. The motor 67 drives the rack gear 6 to open and close the movable deflector 3 through gears.

The gear transmission 6 includes an arc-shaped rack 61 and a motor 67 that can be rotated forward and backward. The arc-shaped rack 61 is provided with a support groove 68, and a fixed shaft 62 passes through the support groove 68 and is fixed on the support seat 67. .

The support seat 67 is also provided with a stroke switch 64, and the switch contact piece 63 of the stroke is arranged on the arc-shaped rack 61

The forward and reverse motor 67 and travel switch 64 are electrically connected with the control box.

The gear transmission device 6 is installed in the center of the range hood body 5 , and the arc-shaped rack 61 is movably hinged to the hinge seat 7 in the center of the movable deflector 3 .

Working principle: As shown in the figure, when in use, turn on the working switch on the control box, the control box controls the motor to rotate forward, and drives the arc-shaped rack 61 of the rack transmission device through the gear, and the support groove 68 of the arc-shaped rack 61 is fixed Slide on the shaft 62 so as to push the deflector 3 to rotate around the living hinge 2 to achieve the effect of opening the deflector 3. After the deflector 3 is opened, a certain angle is formed between the deflector 3 and the range hood body. The new range hood is a side-drawing range hood, and the lampblack easily escapes upwards, resulting in the disadvantage that the lampblack can not be sucked cleanly. However, the deflector 3 opened in the utility model plays a guiding role for the lampblack, forming a larger guide angle, It can slow down the rising speed of the oil fume and ensure that the range hood has enough time to absorb the oil fume. Furthermore, the opening of the whole deflector 3 has a larger smoking opening compared with the traditional range hood, and the oil fume inhalation resistance is smaller, making the whole The machine smokes more smoothly. When the stop switch is selected, the wind wheel stops working, and the motor reverses to drive the deflector 3 to close. When the switch contact piece 63 of the stroke on the arc rack 61 contacts the travel switch, the motor stops working, and the deflector is closed. Finally, compared with the traditional fixed deflector type range hood, the utility model has the advantages of simple structure and convenient use. The deflector can be opened or closed automatically, and the smoking port is not exposed, so that the appearance of the whole machine is beautiful and tidy, and it can also prevent the lampblack from pouring back , The oil fume is sucked clean and so on.
