Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a cooker for cooking an object to be cooked by detachably mounting and rotating a grater cutter or another cooking blade. .

[Prior Art] Conventionally, as a cooking device 1, as shown in FIG.
A lowering cutter 4 is detachably mounted on a drive shaft 3 which penetrates through the bottom surface of the container 2 placed in the container and protrudes into the container 2 and is rotated by a motor (not shown) in the main body 1a. Blade 4a formed on the surface of the lowering cutter 4
In addition, there is a known one in which an object to be cooked in a container 2 is brought into contact with the object. The cooking device 1 can perform cooking other than the lowering by attaching a cooking blade such as another slice blade (not shown) such as the lowering cutter 4 to the drive shaft 3. A holding portion 4b projecting upward is formed at the center of the lowering cutter 4 so as to be easily attached and detached when replacing the cooking blade. During use of the cooker 1, the upper opening of the container 2 is closed by the lid 2a.

By the way, because of the holding portion 4a protruding from the center of the grate cutter 4, the object to be cooked must be diced into a 2 to 3 cm square, which is within the approximate radius of the grate cutter 4. I had to.

For this reason, in order to make the grater, it is necessary to prepare
It had to be diced to ~ 3cm square, which was troublesome.

Therefore, it is conceivable to form the surface of the grater cutter 4 on a flat surface without projections such as the holding portion 4a so that the food can be cooked in a large size without being diced.

[Problems to be Solved by the Invention] However, in such a cooking device 1, when the outer diameter of the object to be cooked is substantially the same as the major axis of the grate cutter 4, the contact area is large in addition to the contact area. Since the center of gravity of the food is close to the center of the lowering cutter 4, it is difficult to turn it over against centrifugal force.
If the outer diameter is substantially the same as the radius of the
The radish R in the container 2 comes into contact with the side surface of the container 2 due to the centrifugal force generated by the rotation of the container 2 and rises so that the radial direction that has been in the horizontal state becomes the vertical direction. If the radish R comes into contact with the lid 2a as it rises, the radish R applies centrifugal force due to the rotation of the cutter to the lid, and as a result, there is a problem that the lid is pushed up by a strong force.

The present invention has been made in view of the above problems,
The purpose is to cook a large-diameter object in a container as it is without cutting the object into small pieces, and to push up the lid even when the object stands up. It is to provide a cooker without any.

Means for Solving the Problems In order to achieve the above object, the present invention provides a motor mounted on a main body, penetrating the bottom of a container having an open top, projecting into the container, and a motor in the main body. On the drive shaft rotated by the above, a grater cutter having a grater blade on the upper surface is detachably mounted, covers the upper part of the cutter and closes the opening with a lid, and presses the lid to drive the motor. A cooking device for cooking the object to be cooked in the container, wherein the upper surface of the grate cutter is formed in a flat shape, and the height from the upper surface of the grate cutter to the upper part of the lid is defined by the radius of the grate cutter. It is characterized by being made larger.

[Function] When the grate cutter is rotated by the cooker having the above-described configuration, the object to be cooked in the container rises so that the radial direction that has been in the horizontal state becomes the vertical direction while abutting the side surface of the container. Since the diameter of the object to be cooked is substantially equal to or less than the diameter of the lowering cutter, the object to be cooked does not come into contact with the lid when the object to be cooked rises. That is, when the object to be cooked comes into contact with the lid, centrifugal force due to the rotation of the cutter is applied to the lid, and as a result, the lid is not pushed up by a strong force.

Hereinafter, an embodiment of a cooking device according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, the cooker 10 includes a drive shaft 13 that penetrates a bottom surface of a container 12 placed on a main body 11 and protrudes into the container 12.
The drive shaft 13 is rotated by a motor (not shown) in the main body 11. The container 12 has a lid 14 having a handle 12a formed on a side surface and closing an upper opening, and the lid 14 is formed with a switch portion 14a for connecting and disconnecting a contact 11a formed on the main body 11. I have. On the upper part of the drive shaft 13, a grater 15 which is rotated by the rotation of the drive shaft 13 is detachably mounted. Further, a concave portion 16 having an opening 16b penetrating the bottom wall 16a and extending along the bottom wall 16a is formed in the upper portion 14b of the lid 14. The recess 16 functions as an oil injection port for injecting edible oil such as mayonnaise used for cooking the food into the container 12.

The cooker 10 is provided with a lid 14 from the upper surface of a grater 15.
Is set to be larger than the radius of the lowering cutter 15 and the height H of the space above the lowering cutter 15
Is larger than the radius of the lowering cutter 15.

As shown in FIG. 2, the lowering cutter 15 includes a lowering unit main body 20 and a lowering unit main body 20 mounted on the lowering unit main body 20.
(See (a)).
And the upper surface of the lowering cutter 15 is flat.

The lowering unit main body 20 is formed in a disk shape having the lowering blades 21 radially arranged on the front surface 20a, and a through hole 22 penetrating the front and back surfaces is formed at the center. On the back surface 20b side, a flange 22a forming the periphery of the through hole 22 is provided so as to protrude. Two locking projections 23 are formed on the inner peripheral surface 22b of the through hole 22 at regular intervals. Locking protrusion 23
Has a cross shape in a plan view, and the upper end 23a has a surface 2
It is formed in an embossed state having the same surface as 0a and protruding from the inner peripheral surface 22a (see (b)).

The turntable 30 has a cylindrical shaft portion 31 into which the drive shaft 13 is inserted and mounted, and a fitting portion 32 formed above the shaft portion 31. The fitting portion 32 is formed in a disk shape having the same outer diameter as the inner diameter of the through-hole 22, and can be closed by fitting into the through-hole 22. Also, with the grater blades 21 arranged in a cross shape on the front surface 32a,
The shaft 31 is protruded from the central portion on the 32b side.

The fitting portion 32 has a rectangular planar shape and an outer peripheral side surface.
A recess 34 having an opening 33 also on the 32c side is provided at equal intervals.
It is formed in the place. The recess 34 functions as a finger hook when taking out the fitting portion 32. Both sides of the opening 33 are cut off so as to enlarge the diameter of the opening 33 except for the upper end portion of the opening 33 of the fitting portion 32. Therefore, on both sides of the opening 33, a slope 33a facing inward and a vertical surface 33b below the slope 33a are formed (see (c)).

When the locking projection 23 enters below the slope 33a, the locking projection 23 is locked as shown in FIG. Then, the slope 3 into which the locking projection 23 enters from the surface 32a.
3a The distance a to the lower part, and the upper end 2 of the locking projection 23 from the surface 20a.
The distance b to 3a is the same length.

For this reason, from the back surface 20b side of the lowering unit body 20, the fitting unit 3
2 is fitted into the through hole 22, the turntable 30 is mounted, and the turntable 30 is rotated manually or by the operation of the cooking device 10 to engage the engaging protrusion.
23 into the lower part of the slope 33a, the surface 3a of the fitting part 32 having the surface 20a of the lower part body 20 and the lower blade 21.
2a can be made substantially flush (see FIG. 3).

Next, an example of the operation of the cooking device having the above configuration will be described.

First, a case will be described in which the radish R to be cooked is cut into large pieces without dicing, and the outer diameter is formed to be substantially the same as the outer diameter of the grated part body 20.

As shown in FIG. 4, this radish R is
Place on top of 15. The radish R has a size such that the outer diameter is within the outer diameter of the lowering unit body 20 and the surface of the lowering unit body 20
Since 20a and the surface 32a of the fitting portion 32 are substantially flush with each other, the entire lower surface side of the radish R comes into contact with the grater blade 21 formed over the entire surface of the grater cutter 15 ( (A)).

Press the lid 14 and lower the cutter by driving the motor
Rotate 15 By rotating the grater cutter 15, the container
The radish R in 12 is revolved or rotated around the drive shaft 13 while being lowered by the grater blade 21 while being in contact with the inner surface of the container 12 or the lid 14 (see (b)). For this reason, the lower surface of the radish R is uniformly lowered, not one piece. Especially,
By the grater blade 21 provided on the surface 32a of the fitting portion 32, compared to the case where the grater blade 21 is provided only on the grater portion main body 20,
The parts that are not lowered are not evenly generated.

Next, a case where the radish R to be cooked is formed to have an outer diameter substantially equal to the radius of the grated portion main body 20 will be described.

As shown in Fig. 5, this radish R is
Place on top of 15. The radish R has a size such that the outer diameter is within the outer diameter of the lowering unit body 20 and the surface of the lowering unit body 20
Since 20a and the surface 32a of the fitting portion 32 are substantially flush with each other, the entire lower surface side of the radish R comes into contact with the grater blade 21 formed over the entire surface of the grater cutter 15 ( (A)).

Press the lid 14 and lower the cutter by driving the motor
Rotate 15 By rotating the grater cutter 15, the container
The radish R in 12 is moved down the surface of the lowering cutter 15 (see arrow (a)) and is brought into contact with the inner surface of the container 12 or the lid 14 (see (b)), and is lowered by the lowering blade 21. While revolving or rotating around the drive shaft 13. At this time,
Due to the action of the centrifugal force, the radish R tends to move upward along the inner surface of the container 12 or the lid 14, so that the lower surface of the radish is cut into a cone (see (b)). Therefore, the radish R is in a state where the lower surface is along the inner surface of the container 12 or the lid 14, and tends to be turned over. The radish R, which is about to be turned over, rises (see (b)) so that the radial direction that was in the horizontal state becomes the vertical direction.

However, since the height H from the upper surface of the lowering cutter 15 to the upper portion 14b of the lid 14 is formed to be larger than the radius of the lowering cutter 15, the radish R rises up and the lid
There is no contact with 14. That is, when the radish R comes into contact with the lid 14, centrifugal force due to the rotation of the cutter 15 is applied to the lid 14, and as a result, the lid 14 is not pushed up by a strong force.

Regardless of the size of the radish R, regardless of the size of the radish R, the radish R is placed on the cutter 15, the lid 14 is attached to the container 12, and the switch is operated by further pressing the lid 14. To a height that allows

By the way, when the cooker 10 is started, if the radish R is positioned at the center of the lowering cutter 15, it moves by centrifugal force and collides with the inner surface of the container 12 or the lid 14. Although the impact of the collision is not great, before colliding with the inner surface of the container 12 or the lid 14, it collides with a corner of the lid 14 and tries to lift the lid 14. However, in the cooker 10, in the case of a high radish R,
Since the lid 14 cannot be attached because it hits the bottom wall rear surface 16c of the recess 16 as an oil injection port, it is possible to prevent the use of the radish R that collides with the corner of the lid 14 at startup. it can.

In addition, the cooking device 10 can mount another cooking blade, such as a slice blade (not shown), on the drive shaft 13 in place of the lowering cutter 15, and perform cooking other than the lowering. When removing the lowering cutter 15 from the drive shaft 13 at the time of replacing the cooking blade, the fingers are hung up on both the recesses 34, 34 of the fitting portion 32 and lifted upward. At this time, the engagement protruding portion 23 enters below the inclined surface 33a and the fitting portion 32 and the lowering portion main body 20 are engaged with each other, so that the lowering portion main body 20 and the turntable 30 can be integrally removed.

Then, after cooking is completed, the lowering cutter 15 is divided into the lowering unit main body 20 and the turntable 30 so that the other cooking blade is mounted on the drive shaft 13 so that the cooking blade and the lid in the cooking device 10 are removed. It can be stored in the space between 14.

In the above-described embodiment, the lowering cutter 15 is composed of the lowering section main body 20 and the rotating table 30 formed separately, but is rotated by the lowering section main body 20 in which the surface of the lowering cutter 15 is a flat surface. It may be formed integrally with the base 30 attached.

[Effects] As described above, the cooker according to the present invention is
A grater cutter having a grater blade on the upper surface is detachably attached to a drive shaft that is protruded into the container and penetrates the bottom surface of the container having an open upper part mounted on the main body and is rotated by a motor in the main body. A cooker for mounting, covering the upper side of the cutter and closing the opening with a lid, and pressing the lid to drive the motor to cook the food in the container, An upper surface is formed in a planar shape, and a height from an upper surface of the grater to an upper portion of the lid is larger than a radius of the grater.

For this reason, a large-diameter object to be cooked can be directly put into a container and cooked without finely chopping the object to be cooked.

Also, if the diameter of the object to be cooked is substantially equal to or less than the radius of the grate cutter, when the grate cutter rotates, the object to be cooked rises while contacting the side of the container due to centrifugal force. Is approximately equal to or less than the radius of the lowering cutter, so that the object does not come into contact with the lid when the object rises. That is, when the object to be cooked comes into contact with the lid, centrifugal force due to the rotation of the cutter is applied to the lid, and as a result, the lid is not pushed up by a strong force.

Also, when cooking a large material having a diameter substantially equal to the diameter of the cutter, the center of gravity of the material is located near the center of the cutter, so that the material rises while abutting the side surface of the container due to the centrifugal force of the cutter. There is no problem, and the lower surface of the material is evenly lowered without unevenness.
