Abstract
The present invention relates to a blower fan for sterilization. The existing centrifugal blower fans only have a blowing function but do not have a disinfecting function, so excessive pathogens are accumulated in a blowing system after long-term use, and delivered air contains lots of bacteria; thus, the infection pathogenesis opportunities of people are greatly increased. The present invention comprises a spiral casing and an air passage formed by the spiral casing, wherein both ends of the air passage are provided with an airflow inlet and an airflow outlet, and a centrifugal wind wheel is arranged in the spiral casing. The present invention is characterized in that an inner cavity of the spiral casing is provided with an ultraviolet generator. The present invention can sterilize the air flowing through the air passage in an omnidirectional and dynamic mode, so the disinfection is thorough and complete, and functions are added to the existing blower fans. The present invention has the advantages of compact structure and high universality.
Description
[technical field]
The present invention relates to a kind of air-supply machinery, especially a kind of centrifugal blower with disinfective action.
[background technology]
Existing centrifugal fan, the centrifugal blower such as being used for the terminal coil pipe of central air-conditioning place only has the air-supply function, and does not possess sterilizing function.Owing to carry pathogenic bacteria in the air, after it enters air conditioning system, can pollute air conditioning system, along with the air conditioning system increase of service time, after the intrasystem pathogenic bacteria quantity accumulation, the air that causes supply air system to be sent contains more antibacterial, has increased people's infection morbidity chance.
At present, the problem that the air of supply air system being sent for solution carries out disinfection, the technical scheme that many " air disinfector " occurred, ZL00218637.3 and two patents of ZL01226496.2 such as the applicant, its quartz burner is arranged in the outer ventilating duct of blower fan, utilize ultraviolet that air is carried out disinfection, the air-flow that these " air disinfectors " are sent directly blows to places such as office, inhabitation, food and drink, amusement.But its structure is different with blower fan with purposes, and fluorescent tube is positioned at outside the volute of blower, is difficult to directly be applied in the air-supply passage and the terminal coil pipe place of central air-conditioning.
[summary of the invention]
The technical assignment of the technical problem to be solved in the present invention and proposition provides a kind of centrifugal fan with sterilizing function, when making this blower fan have sterilizing function, strengthens its versatility.For this reason, the present invention takes following technical proposals:
Blower fan for sterilization, comprise spiral case and the air channel that is formed by spiral case, the two ends in air channel have the entrance and exit of air-flow, and centrifugal wind wheel is set in spiral case, it is characterized in that along the cambered surface inwall of spiral case ultraviolet generator being installed at the inner chamber of described spiral case, this inwall forms reflecting surface simultaneously.Reflecting surface has the ultraviolet reflection focussing force, and it not only can fully improve ultraviolet utilization rate, especially ultraviolet reflection, focusing can be carried out omnibearing irradiation from different angles to air draught, and Disinfection Effect is good.
As to further improvement in the technical proposal and perfect, can take following concrete technical measures:
Have arcuate groove on the cambered surface of described spiral case, described ultraviolet generator is an arc, is installed in this arcuate groove.The principle of this constructor interflow mechanics reduces windage, guarantees the smooth and easy circulation of air-flow.
Described arcuate groove and spiral case cambered surface are integrally formed.Normally punching press formation from inside to outside on the cambered surface of volute of blower.
Described arcuate groove is fixed on the default through hole of spiral case cambered surface wall.Be convenient to installing/dismounting.
Described ultraviolet generator is fixed by the anchor ear of being located on the spiral case, is convenient to installing/dismounting.
The present invention is by being provided with ultraviolet generator in the spiral case of centrifugal fan, can carry out omnibearing dynamic sterilization to the air-flow in the air channel of flowing through, blower fan is had air-flow disinfectant function, can be used in the various occasions that need to use blower fan, especially be fit to use in air conditioning system; Its compact conformation, highly versatile.
