Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric cooking machine such as a mochi making machine used in general households.

Conventional structure and its problems Conventionally, in this type of electric cooking machine, the first
As shown in FIGS. 2 and 3, a steam tank 1 of a steam generator, an electric motor 2 of a drive device,
A cylindrical body 5 with a bottom is provided to cover a structural component 4 including a support fitting 3 for supporting the steam tank 1 and the electric motor 2, and a completed cord box 6 containing a power cord is inserted into the side of the body 5. are doing. The body 5 is inserted from below the structural component 4,
After the screw holes 7 provided at the bottom of the support fitting 3 are aligned with the openings 8 at the bottom of the body 5, the legs 9 are attached to these locations with screws 10. Here, semi-finished product state (during assembly process, disassembly for service, etc.)
In this case, the metal part 11 provided below the electric motor 2, which is attached in a suspended state below the upper surface of the support metal fitting 3, is attached to the support metal fitting 3 so that the metal part 11 provided below the electric motor 2 does not directly hit the floor etc. and cause the electric motor 2 to malfunction. Generally, the bottom A of the metal part 11 was located at a height lower than the lower surface B of the metal part 11.

However, with this configuration, when inserting the body and attaching the legs, there is no positioning required to align the screw holes at the bottom of the support bracket with the openings at the bottom of the body, so it takes time and effort to match them, and work efficiency deteriorates. ing.

In addition, it is necessary to prevent the metal part of the motor from coming into contact with the floor, etc., so the support bracket becomes higher according to the height of the motor, and at the same time, the height of the product and the packaging also increase, and the material The problem was that costs were rising.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides an electric cooking machine that improves workability and reduces material costs.

Configuration of the Invention The electric cooking machine of the present invention includes an electric motor of a drive device,
It has a support fitting that attaches and supports the electric motor in a state in which it is suspended below the upper surface, and a bottomed cylindrical body that covers and protects the structural parts consisting of the electric motor and the support fitting, and the support fitting has a bottom part. Several protrusions are provided, and the bottom of the body is also provided with an opening (or an outer recess) into which the protrusions fit, and when the support bracket with the motor attached is placed on the floor, etc.
Make sure that the metal part below the motor does not hit the floor, etc.
The lower surface of the protrusion of the support fitting is located below the lower surface of the metal.

DESCRIPTION OF EMBODIMENTS An embodiment (rice cake making machine) of the present invention will be described below based on the accompanying drawings. Figures 4 to 7
In the figure, reference numeral 12 denotes a support fitting made by bending an iron plate, and has several protrusions 13 protruding downward at the bottom thereof. Reference numeral 14 denotes an electric motor mounted so as to be suspended below the upper surface of the support fitting 12, and a metal portion 16 is provided below to smooth the rotation of the main shaft 15. This metal part 16
A recess 18 is formed in the center of the bottom of the motor frame 17 and extends downward through a bearing 19.
A bearing cover 20 is fixed to the upper end. moreover,
A cushioning material 2 is provided between the lower part of the ball bearing 21 which is in contact with the conical recess formed at the lower end of the bearing 15 inserted into the bearing 19 and the recess 18 of the motor frame 17.
2 are provided.

A steam tank 23 is a steam generator installed on the upper surface of the support fitting 12 via an electric motor 14, and is equipped with a heating element 24 on the outer bottom and a bearing of the main shaft 15 above the electric motor 14. 25 and an oil seal 26 are provided.

27 is a hopper detachably attached to the upper end of the steam tank 23 via a tank gasket 28, and 29 is a synthetic resin whose one end is fixed to the upper end of the steam tank 23 via a body gasket 30 so as to cover the hopper 27. It has a wooden ceiling frame, and the upper edge has a drooping outer circumference.

31 is a rotor detachably attached to the upper end of the main shaft 15 passing through the hopper 27; 32 is a bottomed cylindrical body that covers and protects structural parts such as the support fitting 12, the electric motor 14, and the steam tank 23;
A completed cord box 35 is provided with an opening 33 (or an outwardly protruding recess 34) into which the protrusion 13 of the support fitting 12 fits in the bottom, and a power cord is stored in the opening provided on the side. is inserted.

Here, the body 32 is inserted from below the structural component, and the support fitting 12 is inserted into the opening 33 at the bottom of the body 32.
When the projections 13 of the body 32 match, the upper end of the body 32 fits into the hanging part of the ceiling frame 29, and the screw insertion hole 36 at the bottom and the screw hole 37 provided at the bottom of the support fitting 12 automatically overlap. A leg 38 is attached to this screw hole 37 via the body 32 with a screw 39.
40 is a capacitor.

To explain how the above structure works, when a semi-finished product such as a motor attached to a support bracket is placed on the floor, the metal part of the motor will be deformed and damaged if it receives a shock from hitting the floor etc. , eccentricity,
To prevent rotational defects such as seizure, the lower surface of the support metal protrusion 2 is placed lower than the lower surface C of the motor metal to prevent the metal part from coming into contact with the floor, etc. By fitting the protrusion into the opening provided at the bottom of the body, the screw hole of the support fitting and the screw insertion hole of the body are automatically positioned to overlap with each other.

Note that the height of the protrusion of the support metal fitting is located above the lower surface of the leg, so that when the finished product is placed on the floor or the like, the protrusion does not come into contact with the floor or the like.

Therefore, the positions of the leg mounting screw hole and the screw insertion hole are regulated by the protrusion of the support fitting and the opening at the bottom of the body, making it possible to easily attach the body and the leg, improving work efficiency. It is something. Moreover, not only can the material used for the support metal fittings be reduced in terms of the height of the protrusion of the support metal fittings, but also the height of the finished product and the packaged product can be reduced, thereby reducing material costs.

Effects of the Invention As is clear from the above embodiments, the electric cooking machine of the present invention is provided with a downwardly protruding protrusion on the bottom of the support fitting that supports the electric motor in a suspended state. By providing an opening or recess on the bottom of the body that fits into the motor, and providing the lower surface of the protrusion below the lower surface of the metal of the motor, less material is used, improving workability and reducing material costs. can be measured.
