Siphoning type multifunctional ventilating fan

Abstract

The invention relates to a siphoning type multifunctional ventilating fan, comprising a machine case, an isolating curved plate, a siphoning type curved plate, an induction trunk, a siphoning opening, an air inlet, a metal net, a sheath with the metal net and a high-voltage power supply. Based on a siphoning type principle structure and a design of efficiently removing pollutants with oxygen ions, the siphoning type multifunctional ventilating fan can rotate a part of indoor air to siphon outdoor fresh air into a room and mix the outdoor fresh air with the indoor air together and also can efficiently remove pollutants with oxygen ions when the indoor air is exhausts. Therefore, the fresh air can be siphoned, and the temperature of the mixed air is close to the indoor temperature, so people do not feel uncomfortable and the circulating indoor air is also purified. The siphoning type multifunctional ventilating fan disclosed by the invention has the advantages of simple structure, easiness in manufacturing, low cost and small size, and also has multifunction of a ventilating fan, an air purifier and an air-conditioning fan; in addition, due to a circular siphoning type horn-shaped structure, the pressure of an indoor air inlet is increased; and the jetting distance of air is large, and the charge and exhaust of indoor air are relatively isolated so as to avoid mixing.

Description

technical field [0001] The invention relates to a ventilation fan. In particular, it relates to a siphon-type multifunctional ventilating fan which adopts the principle of siphon, can circulate a part of indoor air to siphon in and mix outdoor fresh air while the indoor air is exhausted, and efficiently eliminate pollutants through oxygen ions. Background technique [0002] There are many kinds of ventilating fans in the prior art, and most of them are simple in structure, which can only exhaust air but not intake air, which affects the effect of ventilation. Moreover, there is a large temperature difference between indoor and outdoor in winter and summer, and people dare not introduce fresh outdoor air into rooms that are cooled or heated by air conditioners. Poor, easy to cause air-conditioning disease and endanger health; in order to prevent the above situation from happening, some ventilation fans have been improved to make the indoor air circulate and purify indoors. ...

AI Technical Summary

Problems solved by technology

[0002] There are many types of ventilating fans in the prior art, most of which are simple in structure, and can only exhaust air but not intake air, which affects the effect of ventilation. If you want to inhale and exhaust at the same time, you need to install two, which also brings trouble.

Moreover, there is a large temperature difference between indoor and outdoor in winter and summer, and people dare not introduce fresh outdoor air into rooms that are cooled or heated by air conditioners. Poor, easy to cause air-conditioning disease and endanger health; in order to prevent the above situation from happening, some ventilation fans have been improved to make the indoor air circulate and purify indoors. shortcoming and complex structure

Although some known technologies have been improved, most of them have complex structures, difficult manufacture, and high cost.
