Description

Suspension structure of range hood

This creation is about a shock absorber structure for a range hood, especially one that can effectively reduce noise generation for use in factories, laboratories, and kitchens.

The suction port of a conventional range hood may be round, square, rectangular or elongated. When inhaling, air and contaminants enter through the suction port and are discharged to the outside via the conduit. Since the air flow rate near the position of the suction port is large, the air flow rate away from the suction port position will rapidly decrease as the distance from the suction port increases. Therefore, within a short distance below the suction port, the air flows toward The speed on the upper part has become very small, so that the upward suction force is insufficient, and it is highly susceptible to disturbance airflow from the person walking, fan or air-conditioning operation, so that the soot or pollutants escape with the flow of the disturbance airflow.

In view of the above problems, the current effective improvement method is to add a baffle to the left and right sides of the suction hood of the range hood, and to provide a long strip-shaped suction port with the opening facing downward on the bottom surface of the suction hood, and the suction port The two long sides are respectively parallel to the front end and the rear end of the suction hood, so that when the air suction device in the exhaust pipe at the top of the suction hood is operated, the air suction port is sucked upward and discharged to the outside.

However, in actual use, since the exhaust pipe is directly mounted on the top surface of the suction hood, when the air suction device is operated to allow the airflow to enter the exhaust pipe, the top surface of the suction hood is vibrated, Causing the surrounding surfaces of the suction hood to vibrate, and the shock wave will be in the cavity of the suction hood Internal oscillations, as a result, will greatly increase the noise, making people in the kitchen work floating noise, and even affect the safety of the work.

In view of this, in order to provide a structure different from the conventional technology and to improve the above-mentioned shortcomings, the creator has accumulated many years of experience and continuous research and development improvements, and this creation has not been produced.

One of the purposes of the present invention is to provide a shock absorbing structure for a range hood. By providing a structure of an anti-vibration tube between the bottom end of the exhaust pipe and the top of the suction hood, the utility model can solve the suction device of the conventional range hood. During operation, the suction hood is vibrated to generate noise, which can effectively reduce noise and improve the quality of work.

For the purpose of the above creation, the range hood of the present invention comprises a suction hood, the bottom surface of the suction hood is provided with at least one suction port, and at least one suction port is connected to one of the exhaust ports of the suction hood. The bottom end of the exhaust pipe is connected, and an exhausting device is provided in the exhaust pipe for upward pumping; the main technical feature is that the bottom end of the exhaust pipe of the shock absorbing structure of the creative range hood has a lower convex pipe. The lower convex pipe communicates with the inner cavity of the exhaust pipe, the top of the suction hood has an upper convex pipe, and the upper convex pipe communicates with the inner cavity of the suction hood; the upper and lower ends of the anti-vibration pipe respectively connect the lower convex pipe and the upper convex pipe.

In implementation, the creation further includes a frame surrounding the shock tube, and the top end of the frame is coupled to the bottom end of the exhaust pipe, and the bottom end of the frame is coupled to the top end of the suction hood.

In implementation, the air suction device is a blower having an air inlet on both sides, and the air blower is positioned upright in the exhaust pipe.

In order to facilitate a deeper understanding of this creation, it is detailed later:

Referring to Figures 1 and 2, which is a preferred embodiment of the shock absorbing structure 2 of the hood, wherein the hood 1 includes a suction hood 11, a left vertical plate 12, and a right standing The plate 13, an exhaust pipe 14 and an air extracting device 15 include a lower convex pipe 3, an upper convex pipe 4, an anti-vibration pipe 5 and a frame 6.

The suction hood 11 is substantially rectangular parallelepiped, and the suction hood 11 is defined as a front end near one side of the user, and is defined as a rear end in a reverse direction and away from one side of the user, and defines a left side and a right side when the user faces the suction hood 11; The bottom surface of the suction hood 11 is provided with an air suction port 111 having an opening downward and extending in a straight line. In practice, the air suction ports 111 may be one or more and arranged in a straight line. The suction port 111 includes two long sides and two short sides, and the two long sides are respectively parallel to the front end and the rear end of the suction hood 11. The upper convex tube 4 is formed by extending from the top surface of the suction hood 11 , and the upper convex tube 4 is connected to the inner cavity of the suction hood 11 via an exhaust port 41; the left vertical plate 12 and the right vertical plate 13 are respectively coupled to The left side and the right side of the suction hood 11 are below.

The exhaust pipe 14 is a square riser. The exhaust pipe 14 is vertically positioned with an air extracting device 15, and the air extracting device 15 is preferably a blower having air inlets (151, 152) on both sides for pumping. When the air device 15 is in operation, the air is blown upward by the air suction port 111, and is discharged upward through the air discharge port 41. The bottom end of the exhaust pipe 14 has a lower convex pipe 3, and the lower convex pipe 3 is formed by extending downward from the bottom surface of the exhaust pipe 14, and the lower convex pipe 3 is connected upwardly to the inner cavity of the exhaust pipe 14.
