を示す。Structure of the conventional example and its problems As shown in Fig. 1, the motor cooling structure of the conventional household electric appliance is based on the lower surface of the main body (deep bottom part ti of 141) facing the axial fan u3 fixed to the shaft of the motor 0υ. Bottom of the eye (15
In most cases, a) was simply provided with a plurality of ventilation holes U→. However, the characteristic of axial fan 0 is that the flow of cooling air by the fan includes a flow along the axial direction and a flow in an oblique direction that is a combination of the axial and centrifugal directions.
With the conventional structure marked J, the cooling air can be effectively discharged to the outside of the machine against the flow in the 11111+ direction, but it is not sufficiently effective against the flow in the diagonal direction. There were disadvantages such as increasing the input power and noise, which forced the choice of increasing the diameter or increasing the rotation speed. In the figure (to) is +1f11, tl'! of the lower surface of the main body. 1 indicates the floor or table surface.

なり、人力の低減、騒音の減少等の効果が得られる。Effects of the Invention According to the motor cooling structure of the present invention, the i'! A large number of ventilation holes are also provided on the circumferential side of the bowl-shaped slope, so that in addition to the axial flow of cooling air exhausted from the vents on the bottom of the deep bottom, the flow exhausted in the diagonal direction is also carried out on the circumferential side of the deep bottom. The air can be effectively exhausted to the outside through the ventilation holes, and there are many rigs along the exhaust direction on the lower surface of the main body at the deep bottom, so the air can be exhausted from the ventilation holes in the direction of rotation of the axial fan. The cooling air is rectified by this lip and can be smoothly discharged without causing turbulence. Therefore, the loss of cooling air is extremely small, the cooling effect of the motor is increased, and it is also possible to reduce the diameter of the axial fan and lower the rotation speed, resulting in reductions in human power and noise. .
