Problems solved by technology

[0003] However, the existing fresh air fans have the following disadvantages: (1) The heat exchanger has exchange dead angles, the heat exchange time is short, the waste heat is not fully utilized, and the exchange efficiency is low, resulting in a waste of energy
(2) The design of the air duct and fan is unreasonable, the structure is complex, the manufacturing cost is high, the volume is large, and the air exhaust is not smooth
(3) It is bulky and inconvenient for transportation and installation, especially not suitable for installation and use on windows

Embodiment Construction

[0019] The invention will be described in detail below with reference to the drawings, but the invention is not limited to the following examples.

[0020] Such as figure 1 , figure 2 Shown, a kind of fresh air machine comprises casing 14, heat exchanger 7, filter 12, air blower 2, exhaust fan 8.

[0021] The casing 14 is made of metal, plastic, wood-based panels or other materials. A purification module is arranged inside the casing 14. The purification module is composed of a filter 12 and a blower 2 installed side by side. The filter 12 is a coarse-effect filter , medium-efficiency filter, and one or more combinations of high-efficiency filters. The purification module is a detachable structure, and is movably installed in the casing 14 by buckles, bolts, or inlays. During manufacture or maintenance, the filter 12, blower 2, or the entire purification module can be conveniently and quickly installed or removed.

[0022] The blower 2 adopts an ultra-thin centrifugal fan...

Abstract

The invention relates to a fresh air fan. The fresh air fan comprises a shell, a heat exchanger, a filter, a supply fan and an exhaust fan, the outlet of the supply fan is connected with the heat exchanger, a guide structure is arranged inside the heat exchanger, the fresh air side of the heat exchanger is isolated into multiple segments through the guide structure, the exhausting side inside the heat exchanger is communicated with an exhaust channel, and the exhaust channel is arranged along the periphery of the shell. The fresh air fan has the advantages of being compact in structure, sufficient in waste heat utilization, ingenious in air channel design, low in cost and convenient to install.

Description

technical field [0001] The invention relates to an air treatment device, in particular to a fresh fan. Background technique [0002] The fresh air fan is an effective air purification equipment that can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the fresh outdoor air is sterilized, disinfected, filtered and other measures, and then input into the room. , so that the room is full of fresh and clean air all the time. The fresh air fan uses the fresh air convection technology to achieve convection of the indoor air through independent air supply and induction, thereby maximizing the indoor air replacement. [0003] However, the existing fresh air fans have the following disadvantages: (1) The heat exchanger has exchange dead angles, the heat exchange time is short, the waste heat is not fully utilized, and the exchange efficiency is low, resulting in a waste of energy. (2) The design of the air duct and fan is ...
