DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cooker in which cooking means can cook an object to be cooked in a container by rotating a rotating body.

[0002]

2. Description of the Related Art Conventionally, there has been known an electric cooker having a rotating body having cooking means and rotating in a container by driving an electric motor, wherein the cooking means cooks an object to be cooked in the container by rotation of the rotating body. I have.

As shown in FIG. 6, this electric cooker has a rotating body 2 which is rotated by driving an electric motor (not shown) in a container 1, and is rotated by rotating the rotating body 2. A pair of cutters 3 serving as cooking means formed on the body 2 cuts and cooks an object to be cooked in the container 1. At this time, the rotation of the rotating body 2 can be changed in either the forward or reverse direction by the forward / reverse rotation switching means (not shown) (see (a)).

[0004] The cutter 3 is formed, for example, with different cutting edge angles on both sides (αA ≠ αB) ((b)).
Therefore, different cutting conditions are obtained for the normal rotation direction and the reverse rotation direction of the rotating body 2, and different types of cutting and cooking can be performed according to the object to be cooked by simply changing the rotating direction of one rotating body 2. Can be.

[0005]

[SUMMARY OF THE INVENTION Incidentally, when the direction of rotation of the cutter 3 in the cutting cooking is only in one direction, flow in the vessel 1 of the food to be cut cooking cutter 3
Since the rotation direction becomes a fixed direction, there is unevenness in cutting cooking such that a part of the object to be cooked is easily cut by the cutter 3 but another part is hard to be cut. cooking time becomes poor were those becomes long.

In particular, when the object to be cooked is a viscous violet or vegetable, it is pushed to the inner peripheral surface of the container 1 or moved to the center of the rotating body 2 so that the container 1 or the rotating body Thus, the particles adhered to 2 and hardly hit the cutter 3, and it was inevitable that the particles of the cooked food varied and the cutting efficiency deteriorated.

In the conventional cooking device, the cutter 3 is used.
Is rotated in the forward and reverse directions, but the cutter 3 is rotated in the forward and reverse directions with respect to the normal rotation direction of the rotating body 2 by changing the shape on both sides in the rotation direction such as the blade edge angle for the purpose of performing different types of cutting cooking with one cutter. Different cutting conditions are obtained in different directions. That is, since no consideration has been given to the improvement of the cutting efficiency for one cooking object, when cutting cooking by forward and reverse rotation is performed on the same cooking object,
Cutting efficiency of the food without cut well by the direction of rotation there is a problem that causes an excessive load on the motor in efficiency worse on deteriorates.

The present invention has been made in view of the above problems, and an object of the present invention is to prevent the flow of the object to be cooked from becoming constant in the container by rotating the rotating body in the normal and reverse directions. By improving the efficiency with which the object hits the cooking means, there is no variation in the particles of the object to be cooked, and cooking can be performed under the same conditions during both forward and reverse rotations, thereby improving the cooking efficiency and increasing the cooking time. It is an object of the present invention to provide an electric cooker capable of reducing the load on the electric motor as well as the electric cooker.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electric cooker according to the present invention will be described below with reference to the drawings.

The electric cooker 10 shown in FIG. 1 has a main body case 11 and a container 12 placed on the main body case 11.

The main body case 11 has an operation section 16 which incorporates a rotation switching device (rotation switching means) 15 together with an electric motor 14 beside a mounting section 13 on which the container 12 is mounted.
On the upper surface of the operation unit 16, a rotation changeover switch 18 is protruded together with an ON / OFF switch 17 and the like.

The operation of the electric motor 14 is controlled by a rotation switching device 15.
Pulley 19 attached to the mounting portion 13a
The drive shaft 2 is interposed between the drive shaft 2 and a pulley 21 attached to the lower end of the drive shaft 20 protruding from the drive shaft 2.
0 is transmitted. The electric motor 14 has substantially the same rotation speed during forward rotation and reverse rotation.

The rotation changeover device 15 includes a rotation changeover switch 1
By the operation of 8, the rotation direction of the electric motor 14 can be switched between forward and reverse directions and an arbitrary rotation speed can be selected through control means (not shown) having a switch means and a timer means. .

As shown in FIG. 2, the switching to the forward / reverse rotation direction includes a continuous operation (see (a)) in which the forward rotation of the time T1 and the reverse rotation of the time T2 are continuously repeated, as shown in FIG. Stops for t1 time after forward rotation, then t2 after reverse rotation for T2 time
Intermittent operation (see (b)) that repeatedly stops for a time, etc.
Various operation methods having different rotation times and stop times can be arbitrarily set.

In addition, detecting means (not shown) is provided
The electric motor 14 depends on the type and amount of the food to be put in the container 12.
, And based on the detected information, the rotation time and the stop time are selected according to the type and amount of the object to be cooked, and the continuous operation or the intermittent operation can be automatically performed.

The container 12 is formed in a cup shape having a circular cross-section, and is mounted on the mounting portion 13 with a drive shaft 20 protruding from the center bottom to the inside. The upper opening of the container 12 is closed by the lid 23.

The drive shaft 20 in the container 12 has a rotating body 24
Are detachably mounted. The rotator 24 has a pair of cutting blades (cooking means) 25 arranged at different positions in the diameter position, and can be rotated around the drive shaft 20 in the container 12 by the rotation of the electric motor 14.

As shown in FIG. 3, the cutting blade 25 is made of a thin plate extending from the outer periphery of the rotating body 24 to the vicinity of the inner surface of the container 12, and is line-symmetrical on both sides of a symmetrical line connecting the center of the rotating body 24 to the center of the tip of the cutting blade 25. It is formed in a triangular shape, and has cutting surfaces 26 at both ends in the rotation direction (see (a)).

The cutting angles αA and αB formed at an acute angle between the cutting surfaces 26 and the lower surface are substantially the same (αA ≒
αB) (see (b)).

Therefore, the cutting blade 25 is formed symmetrically with respect to the forward and reverse rotation directions of the rotating body 24, so that the cutting blade 25 can be rotated in either forward or reverse rotation direction of the rotating body 24. In this case, it is possible to perform cutting at the same cutting angle and to cook under the same conditions.

The cutting blade 25 is formed so that the angle formed between the two cutting edges 26 at the tips of the two cutting surfaces 26 and the rotating body 24 in both the forward and reverse rotation directions is substantially the same, so that the rotating body 24 can rotate in either the forward or reverse direction. The cutting blade 25 performs cutting at the same collision angle on the object to be cooked even in the rotation direction of, and cooking under the same conditions becomes possible.

Further, the cutting blade 25 forms the cutting angles αA and αB formed at an acute angle between the two cutting surfaces 26 and the lower surface at substantially the same angle, and has the front ends of the two cutting surfaces 26 in both the forward and reverse rotation directions. The angle between the blade tip line 27 and the rotating body 24 is substantially the same, so that the cutting blade 25 has the same cutting angle and the same collision angle with respect to the workpiece in both the forward and reverse rotation directions of the rotating body 24. And can be cooked under the same conditions.

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

First, the container 12 is mounted on the mounting portion 13 of the main body 11, the rotating body 24 is mounted on the drive shaft 20, and the cutting blade 25 is mounted.
After the object to be cooked is placed in the container 12 in which is disposed, the upper opening is closed by the lid 23 (see FIG. 1).

Then, T is set by the rotation changeover switch 18.
After selecting and setting the operation method such as continuous, intermittent or manual or automatic with each time such as 1, T2, t1, t2, etc., ON / OF
The F switch 17 is turned on.

When the ON / OFF switch 17 is turned on,
The driving force of the electric motor 14 is transmitted to the rotator 24 via the drive shaft 20, and the rotator 24 is, for example, continuously operated to repeat forward rotation and reverse rotation, or after stopping after the forward rotation, Based on the setting information, the inside of the container 12 is rotated by alternately repeating the forward rotation and the reverse rotation, such as an intermittent operation (see FIG. 2) in which the rotation is repeated after the reverse rotation. By the forward and reverse rotation of the rotating body 24, the cutting blade 25 alternately hits the object to be cooked from both directions to cut and cook the object to be cooked.

At this time, due to the reverse rotation of the rotating body 24 after the forward rotation, the cutting blade 25 comes into contact with the object to be cooked in the opposite direction from that of the rotating body 24 in the forward direction. Since the flow of the object to be cut and cooked in the container 12 by only rotation of the container 12 does not become a fixed direction due to the rotating direction of the rotating body 24, the object to be cooked is pushed to the inner peripheral surface of the container 12. There is no possibility that the rotator 24 is moved to the center of the rotating body 24.

Accordingly, there is no unevenness in the cutting cooking in which the object to be cooked hardly hits the cutting blade 25 or the particles of the cooking material vary, so that the cutting efficiency does not deteriorate as a whole and the cooking time becomes longer. Nothing.

As described above, in addition to the fact that the electric motor 14 has substantially the same rotational speed at the time of forward rotation and at the time of reverse rotation, the shape and angle of the two cutting surfaces 26 of the two cutting blades 25 facing the object to be cooked are determined. By making them substantially the same, the same cooking conditions are obtained in both forward and reverse rotations, so that the cutting efficiency of the object to be cooked is deteriorated depending on the rotation direction and the efficiency is deteriorated, causing an excessive load on the electric motor. There is nothing to let them do. This is particularly effective when the object to be cooked is a thick viscous violet or vegetable.

Accordingly, the cutting efficiency is improved, and the cooking time can be shortened and the load on the electric motor can be reduced.

The cutting blade 25 may be a cutting blade 28 having a concave lens longitudinal cross section.

As shown in FIG. 4, the cutting blade 28 has a concave lens longitudinal cross-sectional shape that is symmetrical on both sides of a symmetric line connecting the center of the rotating body 24 to the center of the tip of the cutting blade 28, and A cutting surface 30 having a longitudinal central portion recessed in the rotation direction is provided at both ends in the direction.

Accordingly, the cutting blade 28 is formed symmetrically with respect to the forward and reverse rotation directions of the rotating body 24,
In either of the forward and reverse rotation directions of the rotating body 24, the cutting blade 28 performs cutting at the same cutting angle with respect to the object to be cooked, thereby enabling cooking under the same conditions.

With the cutting blade 28, the objects to be cooked can be gathered between the outer periphery on the tip side of the cutting blade 28 and the inner periphery on the rotating body 24 side without flying the object to be cooked toward the outer periphery of the cutting blade 28. The cooking efficiency can be increased by increasing the number of hits of the object to be cooked.

Other configurations, operations, and effects are the same as those of the cutting blade 2.
Same as 5.

Further, in addition to the rotating body 24 for cutting and cooking, a rotating body 29 for stirring and cooking can be detachably mounted on the drive shaft 20 in the container 12.

As shown in FIG. 5, the rotating body 29 has a pair of agitating plates (cooking means) 30 arranged at diametrical positions.
Can be rotated around.

The stirring plate 30 is arranged such that the container 1
2 is formed of a thin plate reaching the vicinity of the inner surface, and protrudes in the longitudinal direction of the outer peripheral surface of the rotating body 29. This stirring plate 3
At 0, a number of holes 31 penetrating the front and back surfaces are formed, and the holes 31 of one stirring plate 30 and the holes 31 of the other stirring plate 30 are formed to have different shapes or sizes. (See (a)).

The rotating body 29 is set, for example, in a continuous operation in which forward rotation and reverse rotation are continuously repeated, or in an intermittent operation in which the rotation is stopped after the forward rotation and then stopped after the reverse rotation. Based on the information, the inside of the container 12 is rotated by repeating the normal rotation and the reverse rotation alternately. By the forward / reverse rotation of the rotating body 24, the stirring plate 30 alternately hits the object to be cooked from both directions to stir and cook the object to be cooked.

Accordingly, each agitating plate 30 is formed symmetrically with respect to the forward and reverse rotation directions of the rotating body 29, and the agitating plate 30 is moved in both forward and reverse rotation directions of the rotating body 24. In this case, it is possible to perform the cooking under the same condition by performing the stirring in the same state such as the same resistance.

By stirring and cooking the food using the stirring plate 30, the food can be effectively used even when the food is cooled for the intermediate treatment of the cooking of egg whites and soups.

The holes 31 may have the same shape and size as the pair of agitating plates 30, and a plurality of narrow slits 32 extending in the radial direction may be provided in the vertical direction instead of the holes 31 ((b )reference).
