p 8, 1959 R. D. STRUB VIBRATION DAMPENING MOUNT FOR MOTOR Filed Oct. 10, 1956 INVENTOR ROBERT D. STRUB ATTORNEY United States Patent VIBRATION DAlVIPENlNG MOUNT FOR MOTOR Robert D. Strub, Coralville, Iowa, assignor to Amana Refrigeration, Inc., Amana, Iowa, a corporation of Iowa Application October 10, 1956, Serial No. 615,116
3 Claims. (Cl. 248-15) This invention generally relates to the mounting of motors and more particularly is directed to an electrical fan motor mount in an air conditioner Where the conservation of space is of the essence.
It is well known in the art to utilize a single fan motor for providing power to the condenser fan and evaporator fan in the conventional type air conditioner. The fan motor drives the squirrel cage fan which circulates air through the evaporator thus cooling and dehydrating it. The condenser fan which is powered by the same fan motor draws air over the condenser, thereby removing heat from the refrigerant which passes through the condenser coils. In the past, it has been the general practice to mount the fan motor completely inside the machine compartment of the room air conditioner, with only the shaft extending through a vertical partition which supports the evaporator fan in the evaporator compartment.
By this invention, I have provided a novel structure for mounting and assembling a fan motor assembly with a substantial savings in space, but not at the sacrifice of efiiciency or capacity of the air conditioner unit. The partition panel which divides the evaporator compartment from the machine compartment has a removable cupshaped member protruding into the evaporator chamber and in which one end of the fan motor is mounted. Part of the space which is required for the fan motor is provided by the evaporator compartment as well as the machine compartment, thus providing a reduction in overall length of the air conditioner without making it necessary to expand in another dimension.
The principal object of this invention is to provide an improved means for mounting the fan motor in a room air conditioner.
Another object is to provide a fan motor mount which makes possible the conservation of space within the air conditioner.
Still another object of this invention is to provide a fan motor mount which eliminates the effects of vibrations during normal operation.
Still a further object of this invention is to provide an improved structure comprising a fan motor assembly mounting means which includes both the condenser fan and the evaporator fan. I
It is a further object to provide a fan motor mount which facilitates manufacturing and assembly in an other- Wise'in accessible or congested area.
Still another object of the present invention is to provide a fan motor mount and assembly which may be easily disassembled for servicing.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings where the preferred form of the present invention is clearly shown.
In the drawings:
Figure 1 is a vertical cross-sectional view of the room air conditioner containing my invention with certain parts omitted for the purposes of clarity;
shown), a condenser 11, an evaporator 12, and the neces' sary tubing (not shown) to connect the refrigeration components. A decorative front 13 is attached to the outer cabinet 10. The decorative front 13 and the cabinet 10 house the evaporator 12, a filter 15, and the controls for the refrigeration system and the fan motor 16. The decorative front 13 contains a return air inlet 17 located at its lower part and an air discharge opening 18 at the top portion thereof.
The fan motor 16 has a shaft extending from either end; the shaft 19 for the evaporator fan, and a shaft 20 for the condenser fan. In the specific embodiment of the air conditioner which serves as a setting or this invention a sirocco fan 21 is mounted on the shaft 19 and a blade fan is mounted on the shaft 20 all being powered by the fan motor 16. In operation, the sirocco fan 21 draws air through the return air inlet 17, through the filter 15, through the sirocco fan inlet 22, and then discharges the air through the evaporator 12, and thence into the room through the discharge outlet 18. Deflectors may be mounted in the inner discharge opening 18 for directing the air flow into the room. The condenser fan 23 which is mounted on the shaft 20 forces air through the condenser 11 which facilitates the removal of heat from the refrigerant in the condenser coils.
In a preferred arrangement the fan motor 16 is mounted at an angle as shown. The evaporator end 24 of the fan motor 16 is mounted in a cup-shaped bell housing 25 which is secured to the partition panel 26. This panel separates the machine compartment 27 from the evaporator chamber 28.
into the chamber 28 than the bottom 33. Therefore, the tilt of the bell housing 25' corresponds to the angle of the fan motor 16. The bell housing 25 is circular in shape and has a peripheral flange 34 to secure it to the partition panel 26. An embossment 35 of cylindrical form is centrally located in member 25, the diameter and depth of the embossment 35 being determined by the fan motor hub 36. The embossment 35 is cut away to provide three spaced apart and equal sections or arms 37 of substantially L shape the inner ends of the axially outer arms of which are concave defining an aperture 39. The shaft 19 of the fan motor 16 extends through the aperture 39 and the fan motor hub 36 fits into the arms 37 defining embossment 35. The hub 36 is held in place by a triangular-shaped resilient spring clip 40.
The clip 40 terminates at points 41 leaving one apex of the triangle open to assist in forming a resilient motor mount. As shown in Figures 2 and 4, the triangularshaped clip 40 is formed so that the apexes are bent out of the plane of the rest of the clip 40. Thus only the apexes 41 and 42 are in contact with the bell housing 25. The clip 40 is spot welded to the bell housing 25 at both apexes 42, or is otherwise securely held in place at those points. Because of the bend 43 the straight side portions or arms 44 of the clip 40 are maintained in spaced relationship to the bell housing 25. Each side or arm 44 of the triangular clip 40 bridges the space between two adjacent sections or arms 37 and contacts the latter at points 45. Thus, when the motor 16 is placed in the bell housing 25 and the hub 36 is inserted into embossment 35, the triangular spring clip 40 is expanded to receive the hub 36, by forcing the downwardly extending. side arms 44 of clip 40 apart. As hub 36 reaches its innermost position in embossment 35, the side arms 44 of clip 40 snap' into a circumferential groove 46 of the hub 36, thereby holding the motor 16 securely and at the same time free from vibration effects.
A partition panel 26 contains an opening 47 through which is inserted the bell housing 25. This opening is of sufficient size to' accommodate the sirocco fan 21 so that it may be inserted through the opening during the assembly process. The peripheral flange 34 on the bell housing 25 is of sufiicient diameter to form a lap joint on the panel 26, thus completely covering the opening 47. Sheet metal screws 48 or other suitable means may be used to' secure the bell housing 25 to the panel 26.
, The condenser end 49 of the fan motor 16 is secured to' the conditioner base pan 50 by means of the angular support 51. The air conditioner base pan 50 has an embossment 52 to which is secured the angular motor support 51. The support 51 is suitably secured to the fan motor hub 53 and is secured to the embossment 52 by machine bolts 54 or other suitable means.
The fan motor assembly, including the fan motor 16, the bell housing 25, the sirocco fan 21, and the angular motor support 51 can be assembled simply and easily. The fan motor 16 and the bell housing 25 must be assembled first. Place the motor 16 in bell housing 25 with the shaft 19 extending through the aperture 39 and hub 36 fitting into the embossment 35. Expand the clip 40 and release into the groove 46 of the fan motor hub 36. Place the sirocco fan 21 on the shaft 19, then secure the support 51 to the hub 53. Place the whole assembly in the air conditioner and secure the flange 34 to the panel 26 and the angular motor support 51 to the embossment 52. The condenser fan 23 is then placed on the shaft 20 and secured with set screw 55 after the fan motor assembly is placed in the air conditioner. To remove this assembly simply reverse the procedure outlined above.
While in the foregoing specification I have set forth a single structure in considerable detail for the purposes of illustrating one embodiment of my invention, such details ofstructure may be varied widely by those skilled in the art without departing from the spirit of my invention.
