Description

Fan with flow regulating port

Technical Field

The invention relates to a fan for a commercial stove, in particular to an air opening capable of adjusting flow.

Background

Commercial stoves usually require a blower to push fresh air to participate in the combustion, and when used on different stoves and for making different cuisine, the amount of air required is also different. When the same stove is used for daily cooking and making wine mat dishes, the requirements on firepower are different, and the corresponding requirements on the air quantity and the air pressure of the fan are different. This requires that the air flow rate delivered by the blower be adjustable. Because the frequency converter of the fan is expensive, the frequency converter cannot be applied to the field generally. The conventional solution is to add an independent valve on the pipeline of the air pipe, which is not only troublesome to operate, but also has higher installation and use costs.

The air outlet pipe and the rotary valve block are square or circular, the direction of air flow in the rotary shaft perpendicular to the air outlet pipe of the rotary valve block is perpendicular to the direction of air flow in the air outlet pipe, at least one end of the rotary shaft extends out through a through hole in the air outlet pipe, an end portion extending out of the air outlet pipe is provided with an adjusting head, and the adjusting head and the through hole are in close contact with each other or the adjusting head and the outer wall of the air outlet pipe are.

The adjusting head is a crank arm or a disc.

The outer wall of the air outlet pipe is in close contact with the crank arm, and the positioning bulges are arranged on the outer wall of the air outlet pipe and distributed along the stroke direction and the range of the crank arm.

The air outlet pipe is cylindrical, a butterfly-shaped baffle is arranged inside the air outlet pipe, the rotary valve plate is butterfly-shaped and is connected with a central shaft of the butterfly-shaped baffle, an extension body is arranged on one side of the rotary valve plate, the air outlet pipe is provided with a groove for the extension body to extend out, the stroke range of the extension body can enable the rotary valve plate to open or close the opening of the butterfly-shaped baffle, and the opening and closing size can be adjusted.

The extension body is in close contact with the slot of the air outlet pipe, or the outer end part of the extension body is provided with a second handle which is in close contact with the outer wall of the air outlet pipe.

The invention has the advantages and beneficial effects that: the fan is provided with the flow regulating device at the air outlet, so that the size of air flow can be conveniently regulated.

Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "disposed" on another element, it can be directly disposed or attached to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

As shown in fig. 1-3, a fan with a flow regulating port comprises a fan body 1 and an air outlet pipe 2, wherein the air outlet pipe 2 is provided with a rotary valve plate 3 and a regulating head 4, the rotary valve plate 4 is arranged in the air outlet pipe 2, and the size of a channel in the air outlet pipe 2 can be regulated when the rotary valve plate rotates around a rotary shaft 5.

Air-out pipe 2 and rotary valve block 3 be square, the direction of air current in the air-out pipe 2 is gone out to rotary shaft 5 perpendicular to of rotary valve block 3, the one end of rotary shaft 5 stretches out through the through-hole on the air-out pipe 2, the tip that stretches out air-out pipe 2 sets up adjusts head 4, adjust between head 4 and the through-hole or adjust between head 4 and the outer wall of air-out pipe 2 in close contact with.

The adjusting head is a disc.

Example 2

As shown in fig. 4 and 5, compared with embodiment 1, the air outlet pipe 2 of this embodiment is cylindrical, a butterfly-shaped baffle 6 is disposed inside the air outlet pipe, the rotary valve plate 3 is butterfly-shaped and is connected to the butterfly-shaped baffle 6 via a central shaft, an extension body 7 is disposed on one side of the rotary valve plate 3, the air outlet pipe 2 is provided with a slot 8 for the extension body 7 to extend out, and the stroke range of the extension body can enable the rotary valve plate 3 to open or close the opening of the butterfly-shaped baffle 6.

The extension body 7 is closely contacted with the slot 8 of the air outlet pipe 2, or the outer end part of the extension body 7 is provided with a second handle which is closely contacted with the outer wall of the air outlet pipe 2.

Example 3

As shown in fig. 6, compared with embodiment 1, in this embodiment, the adjusting head 4 is a crank arm, the crank arm is in close contact with the outer wall of the air outlet pipe 2 through a plurality of positioning protrusions 9, and the plurality of positioning protrusions 9 are disposed on the outer wall of the air outlet pipe 2 and distributed along the stroke direction and range of the crank arm. The crank arm can be positioned between the adjacent bulges under the action of external force, so that the valve can be adjusted within a certain range of stages.

Intimate contact as used herein means: the acting force (friction force or acting force required by deformation and the like) between the air outlet and the valve plate ensures that the impact of the air flow on the valve plate can not change the angle of the valve plate when the air is ventilated in the air outlet, namely the air flow can not impact the valve plate.

The working principle of the invention is as follows: when the air flow adjusting valve is used, the included angle between the valve plate and the air flow in the air outlet can be adjusted through the rotating body directly outside, or the opening area of the butterfly-shaped baffle plate is covered by the positioning valve plate, so that the size of the air flow is adjusted.
