Abstract
The invention relates to a day-and-night type low-noise draught fan. The day-and-night type low-noise draught fan comprises a hood. A left motor room with the open left end and a right motor room with the open right end are arranged in the hood. A left electric fan is arranged in the left motor room, a right electric fan is arranged in the right motor room, the inner wall of the hood is fixedly connected with the left motor room and the right motor room through supports, the outer side wall of the hood is fixedly connected with a control device electrically connected with the left electric fan and the right electric fan, two timing switches for controlling the left electric fan and the right electric fan respectively are arranged in the control device, and a power supply device for supplying power to the timing switches is arranged in the control device. By the adoption of the day-and-night type low-noise draught fan, the timing switches control the electric fans in different positions in the hood to work alternately in different periods, and night noise is greatly lowered.
Description
Technical field
The present invention relates to one type low-noise fan round the clock.
Background technique
Common low-noise fan mostly adopts and to arrange Sound-proof material and low noise motor in inside to reduce the noise of blower fan, not only noise reduction capability is limited, and function singleness, not only automatically cannot change the position of blower interior electric fan according to the difference of time, and the noise of blower fan round the clock cannot be changed according to the change of position.
Summary of the invention
The technical problem to be solved in the present invention is: for solving above-mentioned Problems existing, provides one type low-noise fan round the clock, solves common blower fan cannot change fan noise problem according to day-night change.
The technical solution adopted for the present invention to solve the technical problems is: one is type low-noise fan round the clock, comprise hood, the left motor room of left end opening and the right motor room of right-end openings is provided with in hood, left electric fan is provided with in left motor room, right electric fan is provided with in right motor room, hood inwall is fixedly connected with by support with between left motor room and right motor room, hood outer side wall is fixedly connected with the control gear be electrically connected with left electric fan and right electric fan respectively, the time switch that two control left electric fan and right electric fan is respectively provided with in control gear, the power supply unit for powering to time switch is provided with in control gear.
Further, in order to keep time switch normally to work, power supply unit is button battery.
Further, in order to reduce noise, the nearly left electric fan in hood inwall two ends and right electric fan position are provided with the puigging for sound insulation and noise reduction.
Further, in order to reduce noise, left and right motor room inwall is fixedly connected with the buffer layer for damping noise reduction.
The invention has the beneficial effects as follows, the low-noise fan of type round the clock of the present invention controls diverse location electric fan in hood by time switch and, in different time sections alternation, greatly reduces noise at night.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
