Description
Technical Field
The utility model relates to an air purifier field especially relates to a two air flue structures of two centrifugal fan.
Background
Along with the requirement of people on the ambient air quality is higher and higher, the development of air purifier trade receives people's favor more and more, also pays more attention to the performance of clarifier. The air duct of the existing purifier mainly uses a single fan or a single air duct design as a main part, when the purifier works, different gears can be realized only by adjusting the rotating speed of the single fan, the air outlet mode of the single air duct is single, therefore, the design of double air ducts of double centrifugal fans aims to reach the same rotating speed, the selectivity is more, one fan can work, and two fans can work simultaneously, because the double air ducts do not influence air outlet, the effect of air outlet of the single air duct or air outlet of the double air ducts simultaneously can be realized, the air conditioner has different working states and strong flexibility.
SUMMERY OF THE UTILITY MODEL
In order to realize the above purpose, the utility model provides a two centrifugal fan double air duct structures, which comprises a housin, be equipped with two centrifugal fan in the casing, two centrifugal fan forms two independent wind channels, two with the casing the air outlet in wind channel is towards same direction, and the air outlet in two wind channels is equipped with out the air grid.
Preferably, the casing includes two center frames, a baffle and a apron, the baffle is located and is connected with two center frames between two center frames, the baffle forms two cavitys with two center frames, two centrifugal fan locate respectively in two cavitys and with center frame connection, the apron is located the one end of center frame.
Preferably, the air outlet grid is arranged on the cover plate.
Preferably, the side wall of the middle frame is provided with an air inlet, and the periphery of the outer wall of the middle frame is provided with guard rails.
Preferably, the centrifugal fan is connected with the middle frame through a first screw, and the middle frame is connected with the partition plate through a second screw.
Preferably, the cover plate is connected with the middle frame in a snap-fit mode.
Compared with the prior art, the utility model, its beneficial effect does:
1. the utility model can work in a single fan air duct and work in two fan air ducts simultaneously through the double-air-duct structure of the double centrifugal fans and two independent air ducts of the two centrifugal fans, thereby meeting the requirements of different customers and having stronger flexibility in realizing the machine performance;
2. the shell of the utility model is detachably connected through screws or buckles, which is convenient for the maintenance of the centrifugal fan;
3. protective guards are arranged on the periphery of the outer wall of the middle frame and used for protecting a fan of the centrifugal fan from being damaged by foreign objects and providing an enough air inlet channel for the centrifugal fan;
4. the cover plate is provided with an air outlet grid for guiding air flow, so that air outlet is uniform.

Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.
The utility model provides a two wind channel structures of two centrifugal fans, which comprises a housin 1, casing 1 includes two center 101, a baffle 102 and a apron 103, baffle 102 is located and is connected through screw two 5 with two center 101 between two center 101, baffle 102 forms two cavities 103 with two center 101, two centrifugal fans 2 are located respectively in two cavities 103 and are connected through screw 6 with center 101, the lateral wall of center 101 is equipped with air intake 104, be equipped with rail guard 105 around the center 101 outer wall, the one end of center is located to the apron 103, two centrifugal fans 2 form two independent wind channels 3 with casing 1, the air outlet of two wind channels 3 is towards same direction, the air outlet of two wind channels 3 accesss to apron 103, be equipped with out wind bars 4 on the apron 103.
The utility model discloses a two wind channels 3 are completely independent, and the air-out can not mutual interference, and the loss of amount of wind can not cause yet in the during operation of an independent centrifugal fan 2. In the aspect of control of the centrifugal fan 2, under the condition of low air volume requirement, only one centrifugal fan 2 can work, air is discharged from a single air duct, air flow is guided through the air outlet grid 4 of the cover plate 103, the air is uniformly discharged, and the single centrifugal fan 2 works, so that electricity and energy are saved; under the condition that the amount of wind required to be high, two centrifugal fan 2 can the simultaneous working, and two wind channels air-out simultaneously produce the high amount of wind, and the air-out bars 4 through apron 103 make the air-out even, and the performance of machine improves by a wide margin, can satisfy different crowds different environment, and to the different performance demands of machine, machine work flexibility is stronger.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
