Problems solved by technology

However, most of the existing fresh air ventilators adopt the design of double air ducts, and one or several larger holes need to be drilled on the wall to set up the air ducts; Realize the inflow of fresh air and the discharge of indoor dirty air, which will increase the volume of the fresh air machine body, which is not conducive to the current market requirements for product miniaturization. At the same time, it will increase production costs, complicate the production process, and inconvenient installation. Therefore , limiting the application and promotion of fresh air ventilators
[0004] In addition, the existing fresh air fans only realize the function of exchanging air with the outside, and have no effect on purifying the indoor air; and in the indoor environment of most families, due to the frequent use of air conditioners, the room is kept in a closed state for a long time. As a result, the indoor air is turbid and the air quality is very poor, so another purifier that can purify the indoor air is needed; in this way, the expenditure of the family is increased and energy is wasted

Embodiment approach 1

[0035] Such as figure 1 , figure 2 As shown, it is a fresh air ventilator of the present invention. The ventilator includes a closed casing 1, and the casing 1 is composed of a front half casing 11 and a rear half casing 12. The closed casing The casing 1 is respectively provided with a first opening 110 leading to the indoor and a second opening 120 leading to the outdoor. The closed casing 1 is located between the first opening 110 and the second opening 120, swinging Ground is provided with a centrifugal fan 2, and this centrifugal fan 2 is provided with air inlet 21 and air outlet 22 (as shown in Figure 3, Figure 4), and the air inlet 21 of described centrifugal fan and air outlet 22 correspond to switch respectively Conducted to the first opening 110 and the second opening 120 .

[0036] From the above, the centrifugal fan 2 of the fresh air ventilator of the present invention has two working positions, and the fan 2 is switched between the two working positions by mea...

Embodiment approach 2

[0044] The principle and structure of this embodiment are basically the same as Embodiment 1, the difference is that figure 1 , Figure 7 and Figure 8 As shown, a filter device 3 is provided in the housing 1 adjacent to the second opening 120 to seal the second opening 120 from the upper part of the housing 1 .

[0045] With such a structure, when the ventilator is sucking air, the air that enters the room from the outside through the second opening 120 is first filtered by the filter device 3, and the filtered air is sucked into the room by the centrifugal fan 2 to make it enter the room. The air is purified for good health.

[0046] In this embodiment, the filter device 3 includes a slot 31 provided on the housing 1 and a filter element 32 inserted in the slot 31 . The filter element 32 can also be provided with a silver ion filter layer to realize the functions of silver ion sterilization and purification.

[0047] In this embodiment, if figure 1 As shown, the filter de...

Embodiment approach 3

[0052] The principle and structure of this embodiment are basically the same as Embodiment 2, the difference is that figure 1 , figure 2 , Figure 6-Figure 8 As shown, the second opening 120 side on the back side of the housing 1 is provided with a third opening 121 leading to the interior; a wind plate (such as Figure 9 , Figure 10 As shown), the wind plate 4 is provided with a ventilation hole 41, and the ventilation hole 41 on the wind plate can be switched to correspond to the second opening 120 and the third opening 121.

[0053] When the ventilator of the present invention performs indoor and outdoor ventilation, the air vent 41 of the wind plate 4 is moved to a position corresponding to the second opening 120, so that the second opening 120 communicates with the air vent 41 (such as Figure 10 shown), at this time, the ventilator can perform indoor and outdoor ventilating functions through the second opening 120 .

[0054] When the ventilator of the present inven...

Abstract

The present invention discloses a fresh wind ventilator which includes an enclosed case, a first opening communicating with indoor and a second opening communicating with outdoor are mounted on the enclosed case respectively; a centrifugal fan is wobblingly set between the first opening and the second opening inside the enclosed case; the air inlet port and air outlet port of the centrifugal fan switches correspondingly to communicate the first opening and the second opening. Only a ventilation duct is set through the second opening between the ventilator and outdoor and only a wobbling centrifugal fan is set inside the ventilator, therefore, the whole ventilator volume is decreased, the structure is simple and convenient for mounting. Meanwhile, air entered into the room can be purified because of a filtration device and a third opening set inside the fresh wind ventilator; indoor and outdoor ventilation and indoor air purification on one ventilator at the same time can be realized through the invention.

Description

technical field [0001] The invention relates to a ventilation device in the field of building ventilation, in particular to a fresh air ventilator. Background technique [0002] In order to achieve the purpose of energy saving, the airtightness of buildings is getting higher and higher at present, so as to prevent the coldness of air-conditioned rooms in summer or the heat loss in winter. Although this can reduce the energy consumption of the building, it also leads to insufficient indoor fresh air volume, resulting in a decrease in indoor oxygen content, an increase in carbon dioxide concentration, and the accumulation of other pollutants (such as VOC, particulate matter, etc.). Undoubtedly this will affect the health of the human body. If the natural ventilation method of opening windows for ventilation is adopted, the cooling or heat of the indoor air will be lost, increasing energy consumption, and outdoor pollutants and noise will also enter. [0003] In order to solv...
