Technical Field
The invention relates to a smoke exhaust ventilator accessory, in particular to an air inlet device capable of expanding an air inlet range.
Background
Kitchen range hood is one of the widely used household fans and is connected with the physical and mental health and benefits of tens of thousands of users. The common fume extractor is to drive the blades (hour wheel, leaf fan) to rotate by the motor, and to extract and separate fume by centrifugal force. At present, most of blades of a smoke exhaust ventilator (fan) adopt or imitate traditional wheel type (squirrel cage type) impellers or spiral type blades (impellers and leaf fans) for more than one hundred years abroad. Because the blades mostly have a planar short axial stroke, the action time is short, the suction and exhaust force is small, the blade structure does not conform to the action principle of three-dimensional vortex force, so that the air flow resistance is large, the noise which is mostly difficult (or barely) to reach the national standard is controlled below 75db, the oil-gas separation is incomplete, the accumulated greasy dirt of the blades is difficult to clean, the service life of a range hood (fan) is influenced, and the high noise standard is more seriously influenced, so that the physical and mental health of a user is influenced.
In addition, most of the air inlets of the existing range hoods are of planar structures, and because the area of the air inlets is large, the relative air pressure is low, so that the smoke absorbing capacity of the range hoods is poor, part of oil smoke is easy to escape, and the smoke absorbing efficiency of the range hoods is affected.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the air inlet device which has the advantages of simple structure, low working noise, strong smoking capability and good greasy dirt separation and can expand the air inlet range.
The invention aims at realizing the following modes: an air inlet device capable of expanding an air inlet range is characterized in that: the air guide pipes are positioned between the fixed disc and the oil collecting disc and connected with a smoking port of the fan module.
The air inlet of the air guide pipe is in a waist shape, the air outlet of the air guide pipe is in a circular pipe shape, and the air inlet and the air outlet are in transition connection through a connecting pipe.
The air guide pipe is connected with the fan module through the air inlet, and the air guide pipe is connected with the air suction port of the fan module through the air guide pipe.
The included angle between the butt joint pipe and the plane of the butt joint disk is 30 degrees more than a and less than 60 degrees.
The butt joint pipes are obliquely arranged in the same direction.
The beneficial effects of the invention are as follows: 1. simple structure, convenient assembly, low production cost and market competitiveness improvement. 2. The unique cyclone smoke suction port design can enable the range hood to be accelerated and rotated after entering the air guide pipe to form vortex airflow, and the air suction capability of the range hood is enhanced. 3. The oil smoke is through the slope guide duct for the oil smoke can fully contact with the guide duct inner wall, makes the greasy dirt can liquefy at the pipe wall, has played greasy dirt separation effect. 4. The novel appearance design changes the traditional rigid design, and fully improves the purchasing desire of users.

Description of the embodiments
The invention is described in more detail below with reference to the accompanying drawings. An air inlet device capable of expanding an air inlet range is characterized in that: the air guide pipe type air conditioner comprises a fixed disc 1 and an oil collecting disc 2 arranged in the fixed disc, wherein a plurality of air guide pipes 3 are uniformly distributed on the periphery of the oil collecting disc 2 in an array mode, and the air guide pipes 3 are positioned between the fixed disc 1 and the oil collecting disc 2 and are connected with a smoking port 41 of a fan module 4.
The air inlet 31 of the air guide pipe 3 is in a waist shape, the air outlet 32 of the air guide pipe is in a round tube shape, and the air inlet and the air outlet are excessively connected through a connecting pipe 33.
The air guide pipe 3 and the fan module 4 are also provided with a butt joint plate 5, a butt joint pipe 51 is arranged below the butt joint plate 5, and the butt joint pipe 51 is in butt joint with the air guide pipe 3, so that the air inlet 31 is connected with the smoking opening 41 of the fan module 4.
The included angle between the butt joint pipe 51 and the plane of the butt joint disc 5 is 30 degrees less than a less than 60 degrees.
The butt joint pipes 51 are arranged obliquely in the same direction.
Principle of operation
The air inlet device in the scheme comprises a fixed disc 1 and an oil collecting disc 2 arranged in the fixed disc, wherein a plurality of air guide pipes 3 are uniformly distributed on the periphery of the oil collecting disc 2 in an array manner, and the air guide pipes 3 are positioned between the fixed disc 1 and the oil collecting disc 2 and are connected with a smoking port 41 of a fan module 4; the air inlet 31 of the air guide pipe 3 is in a waist shape, the air outlet 32 of the air guide pipe is in a round tube shape, and the air inlet and the air outlet are excessively connected through a connecting pipe 33. Therefore, the air inlet of the air guide pipe is larger than the air outlet of the air guide pipe, and the air guide pipe is arranged at a certain inclined angle, so that when the fan module generates negative pressure to absorb the oil smoke, the oil smoke can enter from the air inlets of the air guide pipes, and when multiple airflows obliquely enter the range hood, the air speed can be gradually increased along with the narrowing of the air channel, so that the oil smoke forms vortex airflow below the air inlet, the air pressure of the air inlet of the air guide device is improved, and the range hood has stronger smoking capability. Therefore, the oil smoke in the kitchen cannot diffuse in the direction away from the range hood, and the oil smoke removal rate is ensured.
In addition, a plurality of oil smoke coming out of the air guide pipe are collected at the air inlet of the air guide module, so that the oil smoke entering the fan module is collected in a multi-strand spiral mode, the oil smoke is impacted mutually and contacted with the air guide pipe, the oil dirt can be liquefied in the air guide pipe, and the oil smoke separation effect is achieved.
In addition, compared with the traditional planar or arc-shaped shape, the air inlet is more fashionable and novel in appearance, and the traditional smoke exhaust ventilator is changed into a single and rigid shape, so that the purchasing desire of users is improved, and the market competitiveness is improved.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, such as the structure, inclination angle, number of arrangements, etc. of the air guide duct, which are all within the scope of the invention as claimed.
