Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motor holding device for a cooking machine, such as a mixer, that has a built-in electric motor. The purpose is to prevent the main body from deforming even if it rises to a certain height.

An embodiment of the present invention will be described below with reference to the accompanying drawings.
In the figure, 1 is an electric motor built into the main body 4, which consists of a plurality of arms 2 and cushion rubber 3 fixed to the electric motor.
It is fixed to a mounting portion 5 formed on the main body 4 via screws 6.

Reference numeral 7 denotes a rotation shaft of the electric motor 1, and a rotation transmission joint 8 on the main body side is screwed onto the tip thereof.

Reference numeral 9 denotes a cover that covers the top and side surfaces of the electric motor 1. A hole 9a is formed in the top surface of the cover so that the rotating shaft 7 of the electric motor 1 or the rotation transmission joint 8 can freely pass through the cover along with the hole 4a provided on the top surface of the main body 4. ing.

10 is a plurality of blades provided on the lower surface of the rotation transmission joint 8;
When the electric motor 1 rotates, the blades 10 suck air from below the electric motor 1, and have the function of discharging the air that has cooled the electric motor 1 to the outside through the gap 20 between the main body 4 and the container 11 through the hole 9a.

12 is an oil-less bearing fixed to the container 11,
A cutter main shaft 13 is rotatably mounted in the center thereof.

14 is a cutter fixed to the upper end of the cutter main shaft 13;
15 is a rotation transmission joint on the side of the container screwed onto the cutter main shaft 13, 16 is an oil seal, 17 is a container lid, 18 is a back plate having numerous holes that covers the bottom surface of the main body 4, and 19 is a leg.

Next, the operation and operation of the cooking machine configured as described above will be explained. When a workpiece is placed in the container 11 and a 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 14 through a path of the rotation shaft 7, the rotation transmission joint 8, the rotation transmission joint 15, and the cutter main shaft 13, and cuts the object to be cut. In the conventional model, the top surface of the motor 1 is directly fixed to the top surface of the main body 4 with screws A as shown in Fig. 3, so if a high overload is applied to the cutter 14 and the temperature of the motor 1 rises abnormally. Since the air heated to a high temperature by the electric motor 1 and the conductive heat transmitted by the screws A directly hit the mounting part of the electric motor 1 on the main body 4, if a material with a low heat distortion temperature is used as the material for the main body 4, There was a problem that the attachment part of the electric motor 1 of the main body 4 was deformed.

However, in the embodiment of the present invention, the arm 2 is attached to the motor 1 by protruding outside the cover 9 that covers the motor 1, and is fixed to the mounting part 5, so that the temperature of the motor 1 may become abnormal due to overload. Since the cover 9 blocks the heat of the electric motor 1 even if the temperature rises to 1, the temperature of the mounting portion 5 can be prevented from rising.

Furthermore, even if the electric motor 1 is at a high temperature, the arm 2 is air-cooled in the process of heat being transmitted through the arm 2, so the temperature of the arm near the attachment portion 5 becomes low, and thermal deformation of the saw layer attachment portion 5 can be prevented. Furthermore, in the structure of the embodiment of the present invention, in which not only the air that cools the electric motor 1 passing through the inside of the cover 9 but also the cold air passes through the outside of the cover 9, the mounting portion 5 is isolated from the electric motor 1 by the cover 9. Because it is cooled by cold air,
The saw layer can reliably prevent the mounting portion 5 from being deformed by heat. As described above, the present invention can very effectively prevent thermal deformation of the fixed parts of the motor when the temperature of the motor rises abnormally, and its effects are very large.
