DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooker for kneading dough material for bread, for example.

[0002]

2. Description of the Related Art Conventionally, cookers for making dough such as bread by mixing a material such as flour into a container by rotating a rotor blade disposed in the container by an electric motor are widely used in general households and the like. It's being used.

[0003] A rotary wing body disposed in a container of this type of conventional cooking device is configured as shown in Figs. That is, the rotary wing body 100 is formed by integrally forming a cylindrical base 101 having an upper surface with a flat surface 102 and a blade member 103 inclined on the peripheral surface of the base 101 as shown in FIG. A container 11 mounted on a main body 110 in which an electric motor (not shown) is provided inside the rotary wing body 100.
5 is mounted on a transmission shaft 117 that protrudes from the bottom wall 116 of the container 115 and rotates by receiving the torque of the electric motor.

When making bread dough, for example,
A predetermined amount of flour, water, yeast and the like (hereinafter collectively referred to simply as "material") is put in a container 115, and the rotor 100 is rotated and kneaded to produce the dough. In order to produce good dough, it is necessary to mix the material with the entire rotor blade 100 when kneading the material. However, since the conventional rotary wing body 100 is formed by the columnar base 101 having the upper surface formed on the flat surface 102 and the blade member 103 formed on the peripheral surface of the base 101 as described above, Although the member 103 is inclined in the direction of pushing the material upward while rotating, since the kneading progresses and the material becomes sticky, the base 101 is formed in a columnar shape.
The material is wound in a state of being entangled around the base 101,
Further, the material adheres to the root portion of the blade member 103 and the base 101, and the function of pushing up the material is impaired, and the material rotates together with the rotary wing body 101 and is generated by friction between the inner peripheral surface of the container 115 and the material. There is a problem that good kneading cannot be performed because good kneading cannot be performed by the resistance that prevents rotation.

Further, since the upper portion of the base 101 is formed on the flat surface 102, a part of the material rides between the flat surface 102 and the inner surface of the lid 118, and the material on the flat surface 102 stays on the flat surface 102. In particular, when stickiness comes out, the material stays between the lid 118 and remains mixed with the other parts of the material, that is, the material is not kneaded, and there is a problem that a good dough cannot be made. .

[0006]

As described above, in the conventional cooking device, the rotary wing body 100 is formed on a cylindrical base 101 having an upper portion formed on a flat surface 102, and on a peripheral surface of the base 101. Because it is formed by the blade member 103,
If the material becomes sticky, it becomes entangled around the base 101, and the material adheres to the base of the blade member 103,
The function of pushing up the material is impaired, so that it is impossible to mix well with the inner peripheral surface of the container 115 and the resistance caused by friction between the material and the inner circumferential surface of the container 115, so that good dough cannot be obtained. There is a problem, and the upper flat surface 102 of the base 101 and the lid 11
A part of the material rides between the inner surface of the base material 8 and the riding material. When the material becomes sticky, the material stays between the lid 118 and the riding material. There is a problem that can not be made.

A flange portion 79a having a diameter larger than the outer diameter of the shaft press-fitting member 75 is formed at a lower portion of the transmission shaft member 79, and is formed radially at an upper portion of the flange portion 79a for engagement. A rib 79b is formed. The tip of the engagement body 79 is a centering shaft 79c.

The rotation shaft 77 and the transmission shaft 79 constitute a transmission shaft.

Next, the rotary wing body 90 disposed in the container 70 will be described.

As shown in FIGS. 1 to 4, the rotary wing body 90 has a base 91 formed in a substantially conical shape with a spherical top 91a, and is directed outward on the outer peripheral surface of the base 91. And a blade member 92 formed to protrude. An engagement hole 94 is formed in the lower surface of the base 91 and can be inserted into and removed from the transmission shaft 79.

As shown in FIG. 1, the engaging hole 94 is formed so as to have a large diameter at the opening 93 so as to fit the part of the bearing cylinder 74 projecting into the container 70. The inner portion is formed to have a small diameter by forming a step portion 94a, and an engagement concave portion 94b that engages with an engagement rib 79b formed on the transmission shaft 79 is formed in the small diameter portion.

Further, a deep portion of the small-diameter portion in which the engaging concave portion 94b is formed is a centering hole 94c that fits into the centering shaft 79c of the transmission shaft body 79. When the transmission shaft 79 is fitted into the engagement hole 94 of the rotary wing body 90 and the rotary wing body 90 is attached to the fitting shaft 74, the step portion 94a abuts on the flange portion 79a and is positioned. It has become so.

The inclination angle of the surface 92a on the upstream side in the rotation direction of the blade member 92 formed so as to protrude outward on the outer peripheral surface of the base 91 with respect to a perpendicular V passing through the center of the base 91 is shown in FIG. As shown, it is formed at substantially the same angle as the inclination angle of the peripheral surface of the base body 91 with respect to the perpendicular V,
As shown in FIGS. 1 and 3, the upper portion is formed so as to gradually extend outward from a position slightly above the middle position in the vertical direction of the base 91 and downward.

Since the base 91 is formed in a substantially conical shape that becomes thinner as it goes upward, the material to be kneaded as the rotary wing body 90 rotates becomes the base 9.
Since the material moves upward along the inclined peripheral surface of the substrate 1, the material is surely mixed without being entangled or wound around the base 91.

Since the surface 92a on the upstream side in the rotation direction of the blade member 92 is also inclined in the same manner as the peripheral surface of the base 91, the material kneaded as the rotary wing body 90 rotates rotates along the surface 92a. To move upwards,
The material is surely mixed by the substrate 91.

The blade member 92 is formed on the peripheral surface of the base 91 in a tangential direction, that is,
Since the peripheral surface of the blade member and the surface 92a are continuous in a flush state, there is no depression at the root of the blade member as in the above-described conventional one, and a phenomenon that material adheres to this root occurs. And good kneading is possible.

As shown in FIG. 2, the base 91 has two circumferentially extending peripheral surfaces, ie, peripheral walls, at positions substantially opposite to the positions where the blade members 92 are provided. A rib 96 is formed, and the rib 96 functions to prevent the material base 91 from winding.

The opening 71 of the container 70 is
As shown in FIG. 1, a removable transparent lid F is provided.

Further, the speed reducer 40 is removed from the housing 11, and the fitting body 80 attached to the container 70 is fitted in the fitting recess 22 provided in the housing 11, that is, the upper case 20. The coupling 78 of the attached rotating shaft 77 can be used by being engaged with the coupling 29 attached to the shaft 28 provided on the housing 11.

When the container 70 is used by directly attaching it to the housing 11 as described above, it is necessary to cook a dish that requires a large number of revolutions when cooking. In this case, the container 70 is attached to the transmission shaft 79. The rotating wing body 90 is replaced with another cooking wing and used.

Although not shown, operation buttons of various control switches such as a power switch and a timer are arranged on the housing 11.

Next, the operation will be described by taking as an example a case where the material kneaded by the cooking device 1 is bread dough.

In this case, first, the container 70 is connected to the fitting body 8.
0 is fitted into a fitting recess 52 formed in an upper case 50 of the reduction gear transmission 40 attached to the housing 11 and attached.
At this time, the coupling 66 and the coupling 78 are engaged with each other.

Next, the rotary blade body 90 is attached to the transmission shaft 79 protruding into the container 70. Then, a predetermined amount of flour, water, yeast, and the like, which are ingredients of the bread dough, are added. Next, the power switch (not shown) is closed.

When the power switch is closed, the electric motor 30 rotates, and the driving pulley 32 attached to the output shaft 31 rotates. The rotational force generated by this rotation is transmitted via the belt 34 and the driven pulley 33 to the shaft. 28, the coupling 29, the coupling 61, the input shaft 6
0, via the input gear 62a and the output gear 62b of the first speed reducer 62, the input gear 67b and the output gear 67a of the second speed reducer 67, the output shaft 65, the coupling 66, the coupling 78, and the rotating shaft 77. The rotating blade body 90 is transmitted to the transmission shaft body 79 and is integrated with the transmission shaft body 79.
Rotates.

Then, when the rotary wing body 90 rotates, the wing member 92 is rotated while mixing flour, water, yeast, and the like at first. The stickiness gradually increases as the flour and water are mixed with the passage of time, and the material having this stickiness has an increased frictional resistance due to the adhesive force on the outer peripheral surface of the peripheral wall 73 of the container 70 and the rib 73a. At the same time, the inside comes into contact with the rotating peripheral surface of the base 91 and the blade member 92, and the container 70 is forcibly rotated in this state.

The outer side of the material is the peripheral wall 73 of the container 70.
The material whose viscosity is increased because the peripheral speed is low is entangled or wound around the base 91 and the blade member 92 because the ribs 73a and the ribs 72b of the bottom wall 72 receive resistance. Since the surface 92a of the blade member 92 is inclined as described above, the surface 92a of the base member 91 including the blade member 92 gradually moves upward from below with rotation. There is no fixed wrap around, so that the material can be totally mixed with the rotation.

Since the top 91a of the base 91 is formed in a spherical shape, the material is made of the top 91a of the base 91.
There is no stagnation at a, and from this also the material is totally mixed. Further, since the adhesion preventing ribs 96 are formed on the peripheral wall of the base 91, the material is more reliably prevented from being wrapped around the base 91.

Then, the kneading condition of the material is confirmed for a predetermined time or through the lid F. When the dough is kneaded in a predetermined state, the power switch is opened and the motor 30 is stopped, and then the lid F is opened. The operation of making the dough is completed by taking out the dough.

The container 7 after the dough making was completed
0, when cleaning the rotary wing body 90 and the lid F, the container 70
The rotating blade body 90 is removed from the container, and the container 70, the rotating blade body 90, and the lid F are cleaned.

When making dough such as buckwheat, it can be made by adding buckwheat flour and a binder material and kneading them in the same manner. In addition, for example, when making a fresh cream or the like, a rotating blade for foaming is attached in place of the rotor 90, and a higher rotation speed is required as compared with a case where the dough for the bread is made. Removes the speed reducer 40 from the housing 11 and fits the fitting 8
0 is directly attached to the fitting recess 22.

As described above, in the cooking device 1, the rotary wing body 90 provided in the container 70 has a substantially conical base 91 having a spherical top 91 a, and an outer periphery of the base 91. The blades 92 formed so as to protrude outward from the surface of the container 70 allow the material kneaded by friction with the inner peripheral surface of the container 70 to be mixed with the peripheral surface with the rotation of the rotary wing body 90. , The material can be prevented from wrapping around the rotating base 91 and integrally rotating, thereby achieving good kneading.

Further, since the top portion 91a of the base 91 is formed in a spherical shape, the material can be moved without stagnation on the upper portion of the base 91 and can be mixed well.

Further, the blade member 92 is formed to extend tangentially to the outer peripheral surface of the base member 91, and the inclination angle of the base member 91 and the inclination angle of the surface 92a of the blade member 92 on the rotation direction side are substantially the same. As the substrate 91 is rotated, the material is transferred to the surface 92 a of the blade member 92 on the rotation direction side.
, The material can be mixed more favorably by the forcible movement of the blade member 92 and the friction of the inner peripheral surface of the container 70.

Further, since the anti-adhesion rib 79b extending in the normal direction is formed on the peripheral surface of the base 91 at a position substantially opposite to the position where the blade member 92 is formed, the material around the base 91 is formed. Wrapping can be more reliably prevented and good mixing can be achieved.

In the above-described embodiment, the speed reducer 40 is detachably mounted on the housing 11, but may be incorporated in the housing 11.

Further, in the above embodiment, the speed reducer 40 is constituted by the first speed reducer 62 and the second speed reducer 67, which are composed of planetary gears, but this is constituted by meshing a plurality of gears with each other. It may be a reduction gear.

In the above embodiment, the base 9
Although the blade member 92 formed in 1 is formed so as to extend continuously in the tangential direction on the peripheral surface of the base body 91, it may be configured to extend in the normal direction of the peripheral surface. ,
Even in this case, since the base 91 is formed in a substantially conical shape, it is possible to prevent the material from being wrapped around the base 91, that is, entangled. However, when formed so as to extend in the tangential direction as in the above-described embodiment, it is possible to further reliably prevent winding.

[0072]

As described above, according to the first aspect of the present invention, the rotary wing body disposed in the container is formed into a substantially conical body having a spherical top portion, and the outer periphery of the base body. Since the base is formed in a conical body, the material is formed by a blade member protruding outward on the surface, so that the material is formed by friction between the rotation of the rotor blade and the inner peripheral surface of the container. The material kneaded by the generated resistance can be moved upward along the peripheral surface with the rotation of the rotary wing body, so that the material is wrapped around the rotating base and rotates integrally. This has the effect that good kneading can be achieved by prevention. Further, since the upper portion of the base is formed in a spherical shape, the material can be moved without stagnation on the top of the base, and there is an effect that the materials can be mixed well.

According to a second aspect of the present invention, in the first aspect, the blade member is formed to extend tangentially to the outer peripheral surface of the base, and the inclination angle of the base and the rotation of the blade member. Since the inclination angle of the direction side surface is formed to be substantially the same angle, in addition to the effect of the invention according to claim 1, the material is moved upward along the rotation direction side surface of the blade member with the rotation of the base member. Since the rotation can be performed while rotating, the material can be satisfactorily mixed by the forcible movement of the blade member and the friction of the inner peripheral surface of the container.

According to a third aspect of the present invention, in the first or the second aspect of the present invention, an adhesion preventing rib extending in a normal direction on a peripheral surface substantially opposite to a position where the blade member is formed. Is formed, in addition to the effect of the invention described in claim 1 or claim 2, has an effect that winding of the material around the base can be more reliably prevented.
