Abstract
The present invention provides a structure capable of preventing installed air conditioner indoor unit fan from generating freedom. The structure includes fan with molded installing hole, fan motor with rotating shaft and ring shaft sleeve set between molded installing hole and the rotating motor shaft. The ring shaft sleeve consists of two connected ring sleeves with reinforcing ribs and has inner sleeve with diameter smaller than diameter of the rotating shaft of the motor. The present invention installs ring shaft sleeve similar to rolling beaming inside the molded fan hole and the installs the motor shaft via the shaft sleeve so as to control the freedom of the fan for smooth rotation, low noise and less friction between the fan and the air inlet.
Description
Technical field
The present invention relates to a kind of indoor apparatus of air conditioner, particularly a kind of structure that prevents freedom produced during installing indoor unit fan of air conditioner.
Background technology
3.5 of general business air conditioners, the vortex fan of 5 embedded room air conditioners of indoor set four air port smallpoxes, when mounted, fan is by injecting hole 3, elastic caoutchouc 2, axle sleeve iron ring 1 is sleeved on motor shaft 4 enterprising luggages and joins, because elastic caoutchouc 2 is between injecting hole and axle sleeve iron ring 1, so fan exists the free degree, it is bigger to beat during rotation, easily cause itself and air air intake vent to rub, produce abnormal sound, influence fan life, and, be eager the room air conditioner fan mounting structure is improved because the existence of abnormal sound directly affects the sales volume of business air conditioner again.
Summary of the invention
The present invention is in order to solve the problem that exists in the above-mentioned technology, and its purpose is to reduce the installation free degree of fan, reduces fan and beats, improve existing the bad structure of fan.
For achieving the above object, the technical solution used in the present invention provides a kind of structure that prevents freedom produced during installing indoor unit fan of air conditioner, comprise fan that has the injection moulding installing hole and the fan electromotor that has rotating shaft, wherein: between described fan injection moulding installing hole and electric machine rotational axis, be provided with annular sleeve.
Described annular sleeve is to be formed by connecting by inside and outside contour two annulus and the middle reinforcement that is provided with thereof.
The inner ring sleeve tube diameter of described annular sleeve is slightly less than the diameter of electric machine rotational axis.
Effect of the present invention is that the annular sleeve of likeness in form rolling bearing is installed in the fan injecting hole, installs by axle sleeve and motor shaft, and the control fan free degree makes fan running steady, has reduced noise, has reduced the friction probability of fan and air air intake vent.
Description of drawings
Fig. 1 is for improving the forefan structure;
Fig. 2 is the aft-fan structure of improving of the present invention;
The annular sleeve of Fig. 3 for using among the present invention.
The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the structure of freedom produced during installing indoor unit fan of air conditioner that prevents of the present invention.
As shown in Figure 2, in fan production, annular sleeve 5 is placed injecting hole 3, during installation, annular sleeve position and motor shaft 4 suits are fixed, fix with screw, get final product on the fan top.Because annular sleeve 5 is to be formed by connecting by inside and outside contour two annulus and the middle reinforcement that is provided with thereof, and the inner ring sleeve tube diameter of annular sleeve 5 is slightly less than the diameter of electric machine rotational axis 4, such installation has just retrained the free degree of fan rotation, make fan running steady, thereby reduced running noise, reduce the friction probability of fan and air air intake vent, prolonged fan service life.
Claims (3)
1, a kind of structure that prevents freedom produced during installing indoor unit fan of air conditioner comprises fan that has the injection moulding installing hole and the fan electromotor that has rotating shaft, it is characterized in that:
Between described fan injection moulding installing hole (3) and electric machine rotational axis (4), be provided with annular sleeve (5).
2, the structure that prevents freedom produced during installing indoor unit fan of air conditioner according to claim 1 is characterized in that: described annular sleeve (5) is to be formed by connecting by inside and outside contour two annulus and the middle reinforcement that is provided with thereof.
3, the structure that prevents freedom produced during installing indoor unit fan of air conditioner according to claim 1 and 2 is characterized in that: the inner ring sleeve tube diameter of described annular sleeve (5) is slightly less than the diameter of electric machine rotational axis (4).
