Description

Cooker

The present invention relates to a cooking device.

Conventionally, as a rice cooker which is an example of a heating cooker, there is one disclosed in Japanese Patent Application Laid-Open No. 2008-278924 (Patent Document 1). This rice cooker is pivotally attached to the inner pot for storing the rice to be heated, the rice cooker body in which the inner pot is stored, and the upper portion of the rice cooker body, and opens and closes the opening of the inner pot. And a lid.

The upper end portion of the stirring body having a substantially chevron-shaped cross section is rotatably attached to a surface (a surface facing the inner surface of the inner pot) which is the lower surface when the lid is closed. This stirring body is located from the upper end of the inner space of the inner pot to the vicinity of the lower end of the inner space of the inner pot when the lid is closed.

A rotation drive device is installed in the lid body, and the rotation drive device rotates the stirrer to loosen the rice in the inner pot.

However, in the conventional rice cooker, when the lid is closed, the stirring body extends from the upper end of the inner space of the inner pot to the vicinity of the lower end of the inner space of the inner pot, and the upper end of the stirring body is attached to the inner surface of the lid. Therefore, even if it is going to open a cover, there exists a problem that the lower end part of a stirring body is caught in an inner pot, and a cover cannot be opened.

JP 2008-278924 A

Therefore, an object of the present invention is to provide a cooking device capable of preventing the stirring member from obstructing the opening of the lid.

In order to solve the above problems, the heating cooker of the present invention is
An accommodating portion for accommodating an object to be heated;
A heating cooker body in which the housing portion is housed;
A heating unit disposed in the heating cooker body for heating the object to be heated;
A lid that is attached to the top of the heating cooker body so as to be openable and closable, and can be closed so as to cover the accommodating portion;
A rotating body rotatably arranged between the heating cooker body and the lid;
The first end is rotatably attached to the rotating body, and the second end located on the opposite side of the first end is separated from the rotating body or approaches the rotating body. A rod-shaped stirrer that stirs the object to be heated in the housing portion;
A driving unit that generates a driving force for rotating the rotating body,
When the stirrer is substantially parallel to the rotation surface of the rotating body, the width of the stirrer with respect to the rotation direction is narrower toward the upper side.

Here, the “rotation surface of the rotating body” refers to a surface perpendicular to the rotation axis of the rotating body.

According to the above configuration, the stirrer is rotatably attached to the first end of the rotating body, and the second end located on the opposite side of the first end is separated from the rotating body, Since it is possible to approach the rotating body, when the lid is opened, the second end of the stirrer is brought close to the rotating body so that the second end of the stirrer does not get caught in the housing part. can do. Therefore, it can prevent that the said stirring body inhibits opening of a cover body.

Further, the agitator has a first end rotatably attached to the rotating body, and a second end located on the opposite side of the first end is separated from the rotating body or approaches the rotating body. Therefore, the second end of the stirring member can be separated from the rotating member and placed in the object to be heated. Therefore, the stirring object whose second end portion is in contact with the object to be heated can be rotated together with the rotating body, and the object to be heated in the housing portion can be stirred with the stirring object.

Further, when the agitator is made substantially parallel to the rotating surface of the rotating body, the width of the agitating body with respect to the rotation direction becomes narrower toward the upper side. When such a stirrer is rotated and the second end of the stirrer is removed from the object to be heated, the width of the stirrer on the rotation direction side (side toward the rotating body) is reduced. The body can prevent the heated object from jumping up.

In the heating cooker of one embodiment,
The first stirring body and the second stirring body are provided.

According to the embodiment, since the first stirrer and the second stirrer are provided, the object to be heated in the housing portion can be appropriately moved by the first stirrer and the second stirrer. Therefore, stirring of the object to be heated can be sufficiently performed with low vibration.

In the heating cooker of one embodiment,

When the rotary body is viewed from a direction perpendicular to the rotation surface of the rotary body, the first and second stirring bodies are located on the sides of the plurality of gears.

According to the above embodiment, the rotating body is viewed from a direction perpendicular to the rotating surface of the rotating body, including the plurality of gears that transmit the driving force of the driving unit to the first stirring body and the second stirring body. When the first and second stirrers are positioned on the sides of the plurality of gears, the first stirrer and the second stirrer overlap the plurality of gears in the rotation axis direction of the rotating body. In comparison, the thickness of the structure including the rotating body, the first stirring body, and the second stirring body can be reduced.

In the heating cooker of one embodiment,
When the rotating body is viewed from a direction perpendicular to the rotation surface of the rotating body, the plurality of gears are positioned so that the plurality of gears are positioned between the first stirring body and the second stirring body. 1 stirrer and the second stirrer are provided.

According to the embodiment, when the rotating body is viewed from a direction perpendicular to the rotation surface of the rotating body, a plurality of gears are positioned between the first stirring body and the second stirring body. Since the first stirrer and the second stirrer are provided, the rotation of the rotating body can be stabilized. Therefore, vibration of the rotating body can be reduced when the rotating body rotates.

According to the cooking device of the present invention, the first end is rotatably attached to the rotating body, and the second end located on the side opposite to the first end is separated from the rotating body. Since it has a rod-like stirrer that stirs the object to be heated in the container, the second end of the stirrer can be used as the rotor when the lid is opened. It can approach and the 2nd edge part of a stirring body can be prevented from being caught by an accommodating part. Therefore, it can prevent that the said stirring body inhibits opening of a cover body.

Further, the first end is rotatably attached to the rotating body, and the second end located on the opposite side of the first end is separated from the rotating body or approaches the rotating body. Since the rod-shaped stirrer that stirs the object to be heated in the housing portion is provided, the second end of the stirrer can be separated from the rotating body and pierced into the object to be heated. Therefore, the stirring object whose second end portion is in contact with the object to be heated can be rotated together with the rotating body, and the object to be heated in the housing portion can be stirred with the stirring object.

Further, when the agitator is substantially parallel to the rotating surface of the rotating body, the width of the agitating body with respect to the rotation direction becomes narrower toward the upper side. When removing the second end of the body from the object to be heated, the width of the rotating body side (the side going toward the rotating body) becomes narrower in the stirrer, so that the stirrer prevents the heated object from jumping up. Can do.

A miter gear 40, a third miter gear 41, a fourth miter gear 42, a fifth miter gear 43, a sixth miter gear 44, and a seventh miter gear 45 are arranged. The first stirring member 5 is substantially parallel to the second stirring member 6.

According to the rice cooker of the said structure, after putting the desired quantity of rice 50 and the water 51 of the quantity of water according to the quantity of this rice 50 in the inner pot 2, the inner pot 2 is put in the rice cooker main body 1. FIG. The lid 3 is closed so as to cover the inner pot 2. At this time, as shown in FIG. 5, the first and

second stirring members

5 and 6 are accommodated in the first and second accommodation holes 28 and 29 and are in a lying state. Then, the driving force of the rotary stirring DC brushless motor 15 is transmitted to the input shaft 19 of the rotating body 4 to rotate the first miter gear 39 in the direction of arrow R. Thereby, the 1st, 2nd stirring

members

5 and 6 rotate to the arrow D direction, as shown in FIG. 1 in the state which the rotary body 4 does not rotate. The rotation of the first and

second stirring members

5 and 6 in the direction of the arrow D is such that the

first end portions

5a and 6a of the first and

second stirring members

5 and 6 are in the first and second accommodation holes 28, respectively. , 29 abuts against a part of the peripheral edge and stops. Further, when the driving force of the DC brushless motor 15 for rotary stirring is transmitted to the input shaft 19 of the rotating body 4 and the first miter gear 39 is rotated in the direction of arrow R, the first and

second stirring members

5, 6 Rotates together with the rotating body 4. As a result, the rice 50 and the water 51 in the inner pot 2 can be stirred by the first and

second stirring members

5 and 6.

When the first and

second stirring members

5 and 6 are rotated in the direction of arrow D, the second ends 5b and 6b of the first and

second stirring members

5 and 6 and the vicinity thereof are inward. The rice 50 and water 51 in the pot 2 are stabbed. At this time, since the

first surfaces

91 and 94 of the first and

second stirring members

5 and 6 are substantially perpendicular to the direction of the arrow D, a large amount of rice 50 and water 51 are formed on the

first surfaces

91 and 94. Can be moved greatly.

When the lid 3 is opened, the driving force of the rotary stirring DC brushless motor 15 is transmitted to the input shaft 19 of the rotating body 4 to rotate the first miter gear 39 in the direction of arrow L (see FIG. 5). . As a result, the first and

second stirring members

5 and 6 are rotated in the direction of the arrow U in a state where the rotating body 4 does not rotate, and are accommodated in the first and second accommodation holes 28 and 29. At this time, the first and

second stoppers

56 and 57 come into contact with the first and

second stirring members

5 and 6, thereby rotating the first and

second stirring members

Further, the first and

second stirring members

5 and 6 are rotated in the direction of the arrow U, so that the

second end portions

5b and 6b of the first and

second stirring members

5 and 6 and portions in the vicinity thereof are removed from the rice. Since the width of the first and second agitating

members

5 and 6 with respect to the rotational direction becomes narrower toward the arrow U direction when removing from the water 50 and the water 51, the first and second agitating

members

5 and 5 are reduced. 6 can prevent rice 50 and water 51 from jumping up.

Further, the first and

second stirring members

5 and 6 are rotated in the direction of the arrow U, so that the

second end portions
