Abstract
The utility model discloses a fan for an air conditioner, composed of a spiral casing, a bottom plate base, etc. Brushless direct current motor is used as a power source, and an impeller adopts a blade of an arc-shaped structure, so that the utility model has the advantages of simple structure, safe use, small size, light weight, low noise, etc. The utility model can be widely used for instrument units for office automation, such as newfashioned air conditioners, warm air blowers, refrigerators, computers, etc.
Description
The utility model relates to the neotectonics of a kind of air conditioner with blower fan.
Along with the raising of people's living standard, people are also more and more higher to the requirement of air conditioner.In the work of air-conditioned room between often, because the air in the room can only flow in indoor circulation, can not replenish outdoor fresh air, cause the generation of various diseases easily, " air-conditioning sickness " that just it has often been said, so also what have suppressed the demand of people to air conditioner with regard to, how to address this problem, a lot of unremitting efforts have all been done by lot of domestic and international air-conditioning producer, in the inside of air conditioner by adorning various venting gas appliance, because the great majority that adopt are common DC motor, the fan blade of design is rationally not near, cause the noise of air conditioner to increase, also can produce electrical spark during common DC motor work, influence air conditioner safety.
The purpose of this utility model just provides a kind of air conditioner blower fan of novelty.
The purpose of this utility model is to realize like this, the air conditioner blower fan is made up of bottom block, spiral case, brshless DC motor, it is characterized in that: described air conditioner is installed on the bottom block with the brshless DC motor of blower fan, outer outline at brshless DC motor is provided with the draught fan impeller that some arcuation blades are formed by connecting, and the inboard base plate of draught fan impeller is fixed with bolt and brshless DC motor.The described air conditioner impeller of blower fan, it is characterized in that: described impeller is that some arcuation blades and bottom plate combined forming are arranged, and blade is to form with robust plastic pressure injection.
The utlity model has characteristics such as volume is little, in light weight, simple in structure, owing to adopted the power source of advanced brshless DC motor as blower fan, impeller has used firm, durable special plastic compacting to form, and noise is obviously descended, and safe handling property strengthens greatly.
Fig. 1 is a structural representation of the present utility model
1, spiral case 2, impeller 3, connecting bolt 4, brshless DC motor 5, impeller base plate
The utility model is described in further detail below in conjunction with accompanying drawing:
In Fig. 1, brshless DC motor 4 is installed on the base plate, is provided with the draught fan impeller 2 that some arcuation blades are formed by connecting in the outer outline of brshless DC motor, and the inboard base plate of its impeller is fixed on the brshless DC motor with connecting bolt 3.Foul air is entered in the blower fan by the center portion low pressure area of blower fan during work, and impeller 2 runs up under the drive of brshless DC motor 4, and muddy air is discharged from outside the blower fan along volute of blower 1 through blade.The utility model can make dust in the room, peculiar smell, smog etc. discharge by the mode of ventilation, and inspiration fresh air, be widely used on the equipment such as heat radiation in office automation instruments such as trendy gas-discharging type air-conditioning, warm-air drier, refrigerator and computer, instrument, ventilation, exhaust, can obtain reasonable economic benefit and social benefit.
