Description

  The present invention relates to a stirring device that eliminates uneven heating in cooking with a microwave oven.

  When cooking in a microwave oven, there is a risk of uneven cooking of the material to be cooked. Various devices have been developed as devices for preventing this. In addition to providing a rotating plate in the range, there are a device that changes the output of a magnetron (see, for example, Patent Document 1), a device that changes the reflection direction of a microwave (see, for example, Patent Document 1), and the like.

  However, in reality, since uneven heating often occurs, heating is performed more than necessary, and the taste and texture may change. In addition, power consumption increases with prolonged heating.

  This invention is made | formed based on such a situation, and it aims at providing the stirring apparatus with which a microwave oven is mounted | worn so that a heating unevenness may not generate | occur | produce in a to-be-cooked item.

To achieve the above object, according to the present invention, a microwave oven for cooking having a rotating dish,
A mechanism for transmitting the rotational force of the rotating dish via a stirring bar having a stirring blade is formed via a container base, a support column, and a gear, which is a transmission mechanism of the stirring device of the present invention. A stirrer that stirs the inside of a container being heated by the microwave oven using a stirring blade that is rotated by the rotational force of this mechanism is provided.
In order to fix the stirring device inside the microwave oven, a fixing device using a worm gear and a screw screw operated by the gear mechanism is provided.
Although the container used in the microwave oven does not require a dedicated container, the container lid is provided with a dedicated lid in which the lid is broken in order to mount the stirring bar in the container.
Moreover, it is preferable that the said stirring rod is a structure bent so that it may be accommodated in the container used for a heating in a limited space, attaching the housing | casing of the said stirring apparatus in a microwave oven.

A simple stirring device that does not have the transmission function for transmitting the rotational force of the rotating dish of the stirring device and that is simply fixed to the upper housing of the stirring device may be used. In this case, since the rotation speed with respect to the container is one rotation per container rotation, it is preferable to make the stirring blade located at the tip of the stirring rod larger than the above apparatus.
The stirrer is made of a material that does not synchronize with the microwave frequency of the microwave oven and that does not deform or change due to heat.

In this invention, since the inside of the container currently cooking with the said microwave oven is stirred with a stirring rod, the uneven heating is eliminated. Since heating for a long time is not required, an optimum cooking temperature can be obtained, and power consumption can be suppressed.
Since this stirring device has a material and a structure that function even in microwaves, it can be used safely.

  The (a) top view of the stirring apparatus of this invention, (b) sectional drawing.   From the components of the stirring device, (a) a plan view of the gear, (b) a plan view of the lid of the container, and (c) a side view showing the folded state of the stirring rod.   The (a) top view of the simple stirring apparatus which abbreviate | omitted the gear of the said stirring apparatus, (b) Sectional drawing.

1 to 3 show a stirring device according to a preferred embodiment of the present invention. In each figure, common portions are denoted by the same reference numerals, and redundant description is omitted.
The stirring device 5 of the present invention is required to be used for a microwave oven having a rotary table. That is, the rotational force of the rotary table 2 is directly connected to the stirring bar 18 by the container base 11 on which the container 3 on the rotary table is placed, the support column 12 integral with the container base 11, and the internal gear 13 which is the upper structure thereof. Transmission is performed via the stirring rod gear 17 and the intermediate gear 16 located in the middle, and the stirring rod 18 is rotated in the container 3.

  When the knob 21 that can be operated from the microwave front surface 1d is rotated to fix the casing 27 of the stirring device 5 in which the three gears are accommodated to the microwave inner wall 1, the worm gear 22 that is integral with the knob 21 is fitted. The gear 23 rotates. Both sides of the gear 23 have screw screws 24 that pass through the through portions 26 of the housing 27 and are screwed into the fixed pads 25 at both ends. Therefore, when the knob 21 is rotated clockwise, the fixing pad 25 is pressed against the inner wall 1 of the microwave oven and the stirring device 5 is fixed. Further, when the knob 21 is rotated counterclockwise, the fixed pad 25 is drawn into the housing 27 and the stirring device 5 can be removed.

The internal gear 13 at the upper part of the support 12 has a guide 14 at the upper part. When the support 12 rotates with the rotation of the rotating plate 2, the guide 14 is in the guide rail 15 provided at the lower part of the casing 27. , The traveling of the internal gear 13 is stabilized.
The intermediate gear 16 and the stirring rod gear 17 have a protrusion 16t and a protrusion 17t, respectively, are pivotally attached to the lower structure of the housing 27, and stably rotate without the shaft falling off.

FIG. 2A shows a gear mechanism that transmits the rotational force of the rotary table 2. For example, when the internal gear 13 on the upper side of the support 12 rotates clockwise, the intermediate gear 16 fitted to the internal gear 13. Rotates clockwise about the protrusion 16t as a pivot. Then, the stirring rod gear 17 rotates counterclockwise around the protrusion 17t.
According to this embodiment, since the final gear ratio is about 3, when the rotary table 2 makes one clockwise rotation, the stirring bar 18 rotates three times counterclockwise, but the rotary table that rotates clockwise. The number of relative rotations with the container 3 above 2 is four.
FIG. 2 (b) shows a dedicated lid 4, and a stirring bar 18 is attached to the casing 27 of the apparatus in order to cover the container in the range with the stirring apparatus 5 of the present invention attached to the microwave oven. Therefore, the lid is broken into two parts so that the stirring rod 18 can be attached to the container through the hole 4h of the lid, and can be joined by being inserted at the connecting portion 4j.
FIG. 2C shows a state where the stirring rod 18 is bent. In the same manner as described above, the stirring rod 18 connected to the housing 27 becomes an obstacle to take in and out the container 3 while the stirring device 5 is fixed to the inner wall 1 of the microwave oven. Therefore, not only the cover 4 is broken, but the stirring rod 18 can be bent at the refracting portion 18c.
When the stirring rod 18 is used for stirring, the refracting portion 18c is straightened, the socket 18j is lowered from the upper portion 18t of the rod to the use position, and the refracting portion 18c is fixed.
The tip of the stirring rod 18 is a two-blade stirring blade 18p, and is attached by a nut 18b at an angle of about 45 degrees. In order to clean the stirring blade 18p, the nut 18b can be removed and easily cleaned.

FIG. 3 shows a method of using the stirring device 5 described above as a simple structure. The difference from the stirring device 5 described above is a simple stirring device 6 that does not have a mechanism for transmitting the rotational force of the rotary table 2 to the stirring rod. That is, just by fixing the rotating rod 18 and putting it in the container, the rotating blade 18p relatively stirs the material in the container at the same rotational speed as the container rotates.
In order to store the stirring rod 18 in the container, a special lid 4, a stirring rod 18 having a refracting portion 18 c, and a casing 27 having a screw mechanism for fixing the stirring rod 18 to the microwave oven inner wall 1 are necessary. .
