Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking appliance, such as a mixer, which has a built-in electric motor, so that even if the electric motor rises to an abnormal temperature or burns out due to abnormal use, the main body (outer shell) will not deform. This is to prevent this from happening.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an electric motor, which is fixed inside the main body 4 with a screw 3 through a cushion rubber 2. Reference numeral 5 denotes a rotation shaft of the electric motor 1, and a rotation transmission joint 6 on the main body side is screwed onto the tip thereof.

Reference numeral 7 denotes a fireproof cover made of metal or the like that is attached to cover the top surface of the electric motor.A hole a is formed in the top surface of the cover 7, and the rotary shaft 5 of the electric motor 1 or the rotation transmission joint 6 on the main body side is connected to the hole provided in the top surface of the main body 4. It is now possible to penetrate freely.

Further, a gap d is provided between the cover 7 and the main body 4.
Reference numeral 8 denotes a plurality of blades provided on the lower surface of the rotation transmission joint 6 on the main body side. When the motor 1 rotates, the blades 8 suck air from the lower surface of the motor 1, and the air that has cooled the motor 1 is routed through holes a and b. gap c between the main body 4 and the container 9 placed on it
It has a function of discharging the liquid to the outside of the main body 4.

Reference numeral 10 denotes an oilless bearing fixed to the container 9, and a cutter main shaft 11 is rotatably mounted in the center of the oilless bearing.

12 is a cutter fixed to the upper end of the cutter main shaft 11;
Reference numeral 3 denotes a container side rotation transmission joint which is screwed onto the cutter main shaft 11 and is detachable from the main body side rotation transmission joint 6.

14 is an oil seal, 15 is a container lid, and 16 is a back plate that covers the bottom surface of the main body, and has numerous holes e.

17 is a leg.

Next, the operation and operation of the cooking appliance configured as described above will be explained.

When a workpiece to be cut is placed in the container 9 and electric current is passed through the electric motor 1, the electric motor 1 rotates. The rotation of the electric motor 1 is transmitted to the cutter 12 through a path of the rotation shaft 5, the rotation transmission joint 6 on the main body side, the rotation transmission joint 13 on the container side, and the cutter main shaft 11, and cuts the object to be cut. Here, since the cover 7 was not provided conventionally, if a considerable overload is applied to the cutter 12 due to the type of material to be cut, the temperature of the electric motor 1 will rise abnormally and the electric motor 1 will heat the cutter 12 to a high temperature. The air directly hits the top surface of the main body 4.

Therefore, if a material with a low thermal deformation temperature is used as the material for the main body 4, there is a problem that the upper surface of the main body 4 is deformed by hot air. Therefore, if a cover 7 covering the upper surface of the motor 1 is provided between the main body 4 and the electric motor 1 as in the embodiment of the present invention, and a gap d is provided between the main body 4 and the cover 7, the electric motor 1 will rotate and the container side A vane 8 provided on the lower surface of the rotation transmission joint 6 takes in air from a hole e provided in a back plate 16 on the lower surface of the motor 1.

When exhausting air from the gap c between the container 9 and the main body 4, in addition to sucking the air that has cooled the motor 1 through the hole a provided in the cover 7, the air that has cooled the motor 1 can also be drawn directly into the motor 1 from the gap d between the main body 4 and the cover 7.
It also inhales cold air that does not come in contact with the air. For this reason, in the unlikely event that the motor 1
Even if the temperature of the electric motor 1 rises to an abnormally high temperature and the air used to cool the electric motor 1 is at a high temperature, the air passing through the hole b of the main body 4 also draws cold air into the main body 4 through the gap d of the cover 7. Therefore, the temperature of the high-temperature air is lowered, and thermal deformation of the upper surface of the main body 4 can be prevented. Furthermore, if a gap d is provided between the main body 4 and the cover 7, the electric motor 1 will be connected to the main body 3 via the cushion rubber 2.
Since the upper part of the electric motor 1 can move freely by the gap. Therefore, it is possible not only to prevent vibrations generated when the electric motor 1 rotates from being transmitted to the main body 4, but also to prevent the main body side rotation transmission joint 6 and the container side rotation transmission joint 1 from being transmitted to the main body 4.
Even if the rotation axis of 3 is slightly misaligned, the rotation can be smoothly transmitted from the rotation transmission joint 6 on the main body side to the rotation transmission joint 13 on the container side because it is self-aligned. As described above, the present invention provides a cover located between the main body and the electric motor and covers the top surface of the electric motor, and provides a gap between the main body and the cover to prevent thermal deformation of the main body, vibration of the main body, This is extremely effective in that smooth rotation can be transmitted from the side to the container side.
