Central fresh-air device with function of increasing anions

Abstract

The invention discloses a central fresh-air device with a function of increasing anions. The central fresh-air device comprises an outdoor air inlet for pumping outdoor fresh air, an indoor air outlet for pumping indoor vitiated air, an outdoor air outlet for discharging the indoor vitiated air out of a room and an indoor fresh air inlet for conveying fresh air into the room. A point discharge anion generator is arranged inside the indoor fresh air inlet and is provided with an upper electric discharging point and a lower electric discharging point, the upper electric discharging point and the lower electric discharging point are oppositely arranged on the upper side and the lower side of an air channel of the indoor fresh air inlet respectively, a horizontal zero potential current-conducting plate is further arranged between the upper electric discharging point and the lower electric discharging point and grounded. According to the central fresh-air device with the function of increasing the anions, the decay rate of the anions in the fresh air can be lowered, so that the anions in the air can be retained for a long time.

Description

technical field [0001] The invention relates to a central fresh air device with the function of increasing negative ions, and belongs to the technical field of household appliances and air purification devices. Background technique [0002] With the continuous improvement of people's health awareness and requirements, more and more attention is paid to the problem of outdoor air pollution, and with the continuous development of my country's industrial level, PM2.5 is also more and more seriously affecting people's lives; in addition, more and more The organic gas pollution produced by the more complex interior decoration also seriously endangers the health of residents; symptoms such as headache, dry cough, dizziness, nausea, and difficulty in concentrating caused by the above-mentioned indoor and outdoor air pollution factors occur frequently. Negative ions are called vitamins in the air. In addition to neutralizing the positively charged particles in the air to make them se...

Problems solved by technology

[0003] The commonly used central fresh air system, whether it uses HEPA filter or electrostatic dust filter, only purifies the tiny particles in the outdoor air and discharges the indoor polluted air. It can only have the effect of ventilation and cannot produce negative ions. fresh air

Chinese patent document CN204678529U discloses a full-heat fresh air exchanger with negative ion generation function, wherein the negative ion generator is combined with the central fresh air system to realize that the full heat exchanger generates negative ions while delivering fresh air; Specifically disclose the combined structure of the negative ion generator and the central fresh air system, but only disclose that the negative ion generator is installed near the air outlet. The decay rate of negative ions is fast, and the time for negative ions to stay in the air is short, which is difficult to meet the actual use requirements
