Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cooker for rotating a cutting means to cook an object to be cooked in a container.

[0002]

2. Description of the Related Art Conventionally, a cutting and agitating cutter, which is located in a container placed on the upper part of a main body and is rotationally driven by an electric motor in the main body, is rotated by operating a switch for controlling the operation of the electric motor. A mixer is known as an electric cooker that cooks an object to be cooked in a container.

A power cord extends from the rear end of the mixer, for example, to the outside of the main body. When the mixer is not used,
I tried to keep it from getting in the way by bundling the power cords, but the bundling part was still exposed outside the body, and it was inevitable that it would bother you and make it look bad.

Therefore, it is conceivable to store the power cord in the main body.

In this case, the power cord is wound in a layered form and housed in a case to form a cord reel unit, and the cord reel unit is housed in the main body, so that the power cord is easily exposed without being exposed to the outside of the main body. Not only can it be used, but it can also be worn nicely.

The power cord in the cord reel unit is
One end side with the insertion plug attached is located on the outermost periphery, and the other end side with the connection terminal to be connected to the electric motor is located on the substantially center part of the innermost periphery. It is exposed at the center of the side surface.

By the way, when the cord reel unit is stored in the main body, if the electric motor is placed in a lower position so that it can be installed in the vertical direction, the whole mixer is extended in the vertical direction, and the position of the center of gravity becomes high, resulting in poor stability. Therefore, it is desirable to arrange it on the side around the electric motor.

[0008]

However, in the case of arranging on the side of the electric motor, if the outer side surface of the case where one of the connection terminals is exposed is located on the electric motor side, the insulation distance from the electric motor and the routing of the lead wire. A certain distance must be placed between the cord reel unit and the electric motor in order to secure space, etc., and the expansion of the cord reel unit in the installation direction is inevitable, and the main body becomes large, and the mixer is installed and stored. There is a problem in that it requires a large space and causes an increase in cost.

The present invention has been made in view of the above problems, and an object of the present invention is to install a power cord into a cord reel unit and store the cord reel unit in the main body, and to reduce the size of the main body for installation and installation. An object of the present invention is to provide an electric cooker that does not require a large space for storage and can reduce costs.

[0010]

In order to achieve the above object, an electric cooker according to the present invention comprises a cutting means, which is rotationally driven by an electric motor in the main body, in a container mounted on the main body, In an electric cooker that cooks an object to be cooked in the container by rotating a cutting means by operating a switch that controls the operation of an electric motor, a power cord is wound in layers and a power supply terminal is provided on an outer surface. The cord reel unit is arranged vertically in a lateral direction of the electric motor with an outer surface provided with the power supply terminal being located on the side opposite to the electric motor side.

[0011]

The electric cooker according to the present invention, when cooking, pulls out the power cord from the cord reel unit in the main body, puts the object to be cooked in the container attached to the main body, and operates the switch to drive the motor. Let By driving the motor, the cutting means rotates to cook the food in the container. At the end of cooking, the power cord is stored in the main body by winding it around the cord reel unit.

The cord reel unit is arranged vertically on a side of the electric motor with a pair of power supply terminals located on the opposite side to the electric motor side. The cord reel unit has an insulation distance from the electric motor and a lead wire routing space. It is not necessary to secure it and can be placed close to the electric motor.

7c, the motor 16, and the cord reel unit 17 installed vertically are arranged in a line in the front-rear direction of the main body case 11 (see FIG. 5).

At this time, the insertion plug 46a protruding from the take-out port 17a of the cord reel unit 17 passes through the opening 32 of the lower case 14 and is positioned in the recess 33 located at the rear end corner of the main body case 11. ..

Drive shaft 3 protruding from the upper surface of the main body case 11
A driving coupling 52 is detachably screwed into the upper end of the driving member 9. The driving coupling 52 is provided with a plurality of engaging projections 52a on the upper surface of the disk and a plurality of air-blowing blades 52b on the lower surface thereof in a radial pattern. (See FIG. 1).

The container 12 is mounted on the mounting portion 20.

The container 12 has a cylindrical container body 53 having an open upper end 53a and a lower end 53b, and a cylindrical bottle support 54 attached to the lower part of the container body 53 (see FIGS. 1 and 2). ).

The container body 53 has a handle 5 formed on the side thereof.
5 and a lid 56 that closes the opening of the upper end 53a, and is detachably attached to the bottle support 54 via a screw portion 57 formed on the outer peripheral surface of the lower end 53b.

The bottle support 54 has a partition wall 58 which is formed by partitioning the inside of the cylinder into upper and lower parts, and the outer peripheral wall 5
Inner peripheral wall 5 which is spaced apart from 4a and protrudes from the lower surface of the partition wall 58.
4b. A screw portion 59 is formed on the inner surface of the upper portion of the outer peripheral wall 54a.

The partition wall 58 has a step portion 58a on the periphery of the upper surface.
And a rotary shaft 60 that penetrates through the front and back surfaces is mounted inside the adjustment liner 60a so as to be rotatable. A rubber ring 61 is attached to the step portion 58a, and a cutter 62 is attached to the upper portion of the rotary shaft 60 and a driven coupling 63 is attached to the lower portion thereof (see FIG. 1).

As shown in FIG. 10, the cutter 62 has a cutting and stirring blade 64 and a crushing blade 65 which are vertically separated from each other. The cutting and stirring blade 64 having both ends inclined upward cuts and stirs the object to be cooked. The food to be cooked can be crushed by the crushing blade 65 ((a), see FIG. 1).

The cutting and stirring blade 63 and the crushing blade 64 are arranged such that the respective blade portions 64a and 65a are orthogonal to each other (see (b)).

The driven coupling 63 is formed in a disk shape in which a plurality of engaging projections 63a are radially provided on the lower surface (see FIG. 1).

Then, by screwing the screw portion 59 onto the screw portion 57 and integrally mounting the bottle support 54 on the container main body 53, the opening of the upper end 53a of the container 12 can be closed by the lid 56. At the same time, the opening of the lower end 53b is closed by the bottle support 54 via the rubber ring 61, and the cutter 62 is positioned in the lower part of the container body 53 to form a bottle shape.

Further, the bottle support 54 integrated with the container body 53 is mounted on the upper surface 19 of the mounting portion 20 by engaging the engaging claws 50 in the engaged state on the outer side of the inner peripheral wall 54b. The engagement protrusion 52a and the engagement protrusion 63a are engaged with each other, and the drive coupling 52 and the driven coupling 63 are connected to each other in a meshed state (see FIG. 1).

Therefore, the rotation of the motor 16 causes the drive shaft 39 to rotate.
Drive coupling 52 to driven coupling 6 via
3 and the cutter 62 is rotated.

At this time, the bottle support 54 placed on the upper surface 19 is lowered by the two base parts 51a and 51b.
A gap is formed between the upper surface 19 and the upper surface 19, and the rotation of the blower blade 52b caused by the rotation of the drive coupling 52 causes the motor 1 to be sent out of the upper case 13 through the gap.
An air flow passage for cooling 6 is formed.

That is, the blower blade 52b rotates and the gap a
By exhausting the air inside, the air enters through the ventilation holes 31 of the lower case 14, passes through the field assembly 38 from the lower frame 41 of the motor 16 and passes through the through holes of the upper frame 40, and becomes a gap between the upper frame 40 and the back surface 21. The air passage is formed so as to reach the gap a of the above and further pass through the gap between the lower end portion 54c and the upper surface 19 to the outside of the main body case 11 from the opening 49.

A small cup 65 can be detachably attached to the bottle support 54 instead of the container body 53.

The cup 65 has a threaded portion 57 similar to that of the container body 53 formed on the outer peripheral surface of the upper opening. At the bottom, a closed space having a partition wall 58 provided with a cutter 62 as a bottom is formed (see FIG. 1).

Next, the operation of the electric cooker having the above structure will be described.

First, place the mixer 10 on a table or the like,
Holding the insertion plug 46a exposed from the recess 33 of the lower case 14, the power cord 46 is pulled out from the cord reel unit 17 by the required length.

By stopping the withdrawal, the power cord 46 does not return and stops in the withdrawn state. Therefore, the plug 46a is connected to the power outlet.

By connecting the insertion plug 46a to a power outlet, the motor 16 can be energized.

Subsequently, the bottle support 5 is attached to the container body 53.
By integrally mounting the container 4, the cutter 62 is positioned in the lower portion of the container body 53, and the container 12 formed in a bottle shape is mounted on the mounting portion 20 of the body case 11.

After putting the food to be cooked in the container 12 attached to the main body case 11, the lid 56 is closed and the switch knob 37
The motor 16 is driven by operating a and 37b.

When the motor 16 is driven, the cutter 62 is rotated to stir-cut and crush the object to be cooked in the container 12 for cooking.

When cooking, a flash (intermittent) operation is performed by the switch knob 37a or a continuous operation is performed by the switch knob 37b, depending on the cooking method. Continuous operation is
It can be stopped by the switch knob 37c.

At the end of cooking, the power cord 46 is wound around the cord reel unit 17 without stopping by pulling out the plug 46a.

By the way, the cord reel unit 17 is
By arranging the pair of power supply terminals 47 on the opposite side to the motor 16 side and vertically arranging them behind the motor 16, it is not necessary to secure an insulation distance from the motor 16 and a lead wire L wiring space. , Can be placed close to the motor 16.

Therefore, the power cord 46 can be formed into a cord reel unit and stored in the main body case 11, and the main body case 11 can be downsized. Therefore, a large space is not required for installation and storage and the cost is reduced. Down is possible.

In particular, the switch unit 15 and the motor 16
Since the cord reel units 17 are arranged in a line in the front-rear direction of the main body case 11, the main body case 11
The front and rear depth dimensions of the main body case 11 can be made larger than the left and right lateral dimensions of the main body case 11, and the switch knob 37a is located on the front surface of the main body case 11 and is pressed in the front and rear direction.
It is possible to enhance the sense of stability of 37b and 37c during operation.

Further, the switch knobs 37a, 37b, 37
In order to increase the sense of stability when operating c, rubber feet 29a are embedded in the front two legs 29 to prevent slipping, but the front and rear depth dimensions of the main body case 11 are increased. As a result, the pressing direction at the time of operating the switch is positioned between the front and rear legs 29, and the front legs 29 are
Since a downward turning force is applied to them, it is possible to effectively prevent slipping by providing the rubber feet 29a only on the front leg portion 29.

Further, the motor 16 is fixed with the upper portion of the upper frame 40 inserted in the flange 22, and the upper frame 40 made of heat resistant resin is interposed between the upper frame 40 and the upper case 13. This makes it difficult for the heat generated by the field assembly 38, which is a heating element, to be transferred to the upper case 13.

Therefore, the upper case 13 projecting the drive shaft 39 from the opening 49 is not thermally deformed, and the center of the driven coupling 63 of the bottle support 54 placed on the upper surface 19 and the drive coupling of the drive shaft 39. The center of 52 does not deviate.

Further, since it is not necessary to take heat measures for the upper case 13, it is not necessary to use a heat-resistant resin for the upper case 13, and a cheaper general material can be used. The degree of freedom in designing the case 13 is not narrowed, the upper case 13 as a component does not become large, and the cost does not increase.

In addition, since the upper frame 40 and the lower frame 41 are assembled and fixed to the upper case 13 at the same time, the assembling process of the motor 16 is simplified and the cost is reduced.

The cord reel unit 17 is not limited to one having an automatic winding mechanism, but may have a manual winding mechanism by a winding means such as a handle.
In this case, the winding means is connected to the upper case 1 via the transmission means.
By exposing it to the outside, the pair of power supply terminals 47 can be positioned on the opposite side of the motor 16, and the same effect as in the case where the automatic winding mechanism is provided can be obtained.
