Embodiment Construction

[0070] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0071] The present invention adopts Φ130 blades, and its maximum air volume is 600m 3 / h; the design air outlet is 400*80, fully satisfying the 600m 3 / h air volume requirement; the air duct adopts an eccentric variable diameter design; the motor adopts a DC brushless motor, and the operating noise is very small; the noise is low, and the measured noise is 40dB.

[0072] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0073] Such as figure 1 As shown, the large air volume, low noise, and recoverable wall-mounted fan provided by the embodi...

Abstract

The invention discloses a large-blast-capacity low-noise recoverable wall mounting type draught fan and an installing method thereof, and belongs to the technical field of wall mounting type draught fans. An air outlet is formed in the middle of an upper plate of a machine shell, and a metal protective net is embedded into the surface of the air outlet; an aluminum alloy shutter backboard is fixedto the back of the machine shell through a bolt; and a core plate is fixed to a bottom plate of the machine shell through a bolt, and an air flue guide aluminum plate is fixed to the top end of the core plate through a bolt and environmental protection glue. Certain original glass or a certain window in a room can be detached without damage, the draught fan is installed in a window frame, the left and right portions of the draught fan are fixed through aluminum alloy corner proximate matter, and the upper portion of the draught fan is sealed through an acrylic plate; and during recovering, the draught fan is detached, and the glass is installed. According to the large-blast-capacity low-noise recoverable wall mounting type draught fan and the installing method, the maximum wind quantity is 600 m<3> / h; the aluminum alloy shutter overall backboard is adopted, and therefore consideration is given to waterproofing and the air inlet quantity; initial-efficiency and high-efficiency dual-layer filtering is adopted, and therefore PM2.5 and PM10 of air at an air opening are reduced to 0, the air ventilation quantity is greatly improved, and the cost for replacing consumable items is saved;and damage-free installation can be achieved through the method of replacing the glass.

Description

technical field [0001] The invention belongs to the technical field of wall-mounted fans, in particular to a recoverable wall-mounted fan with large air volume, low noise and an installation method. Background technique [0002] At present, the air volume of wall-mounted fresh air fans on the market is generally 300m 3 Below / h (for example, the air volume of the three fathers FA-N280 is 280m 3 / h, Brown BGF-280A air volume is 280m 3 / h, Kelixin KSF-150 air volume is 150m 3 / h, the maximum air volume in Di'an is 120m 3 / h), and large air volume fresh air fans will inevitably have greater wind noise. In addition, almost all wall-mounted fresh air fans on the market are installed by punching holes in the inner wall (usually Φ110~Φ160), which has both safety and There are hidden dangers, and it is impossible to restore the damaged wall. The reason for the small air volume: According to GB3096-1993 "Urban Area Environmental Noise Standard", the residential area belongs to C...
