3 has an annular flange portion 14 extending horizontally in the upper part. The annular flange portion 14 is adapted to be supported by the upper end surface of the rim of the opening 2 of the container 1, and thus has an outer diameter larger than the outer diameter of the fitting portion 7.
At the opening edge of the through hole 11, an inclined annular projecting wall 10a projecting inward of the container 1 is formed, and a cylindrical wall 10b extending upward is formed so as to project.

Engagement protrusions 19 are formed on the outer surface of the vertical annular wall 13 of the lid 10. These engaging projections 19, 19 are inserted into the engaging grooves 3, 3 formed in the fitting portion 7 of the container 1 so as to be able to be inserted and removed, and guide the lid 10. That is, when the cover 10 is attached to the opening 2 of the container 1, the engaging protrusion 19 is inserted into the engaging groove 3, and the engaging protrusion 19 is guided by the engaging groove 3.
When the engagement projection 19 is inserted into the vertical groove 3aa of the engagement groove 3, the lid 10 is inserted into the fitting portion 7 of the container 1, and the engagement projection 19 is inserted into the horizontal groove 3ab connected to the lower end of the vertical groove 3aa. When inserted, the lid 10 is guided to rotate in the circumferential direction, that is, to rotate. Further, when the engaging projection 19 is inserted into the locking groove 3b located at the back of the horizontal groove 3ab, the lid 10 is further advanced toward the bottom of the container 1.

Therefore, when the lid 10 is attached to the opening 2 of the container 1, the lid 10 is inserted into the fitting portion 7, then turned in the horizontal direction, and further pushed toward the interior of the fitting portion 7. To operate. As a result, the engaging projection 19 is moved to the vertical groove 3a.

That is, the outer diameter D ₁₅ of the guide wall 15 is smaller than the inner diameter D ₇ of the inner circumferential wall 7a of the fitting portion 7 (D ₁₅ <D
₇ ) This guide wall 15 is opposed to the inner peripheral wall 7a of the fitting portion 7 with a slight gap. Therefore, the guide wall 15 is slidable along the inner peripheral wall 7a of the fitting portion 7.

Further, on the outer surface of the vertical annular wall 13, an annular fitting groove 1 is located below the guide wall 15.
6 are formed. A sealing member made of an elastic member such as rubber, for example, an O-ring 17 is attached to the fitting groove 16. The O-ring 17 is formed so as to be larger in diameter than the outer diameter of the annular wall 13 when fitted in the fitting groove 16, that is, so that the outer periphery projects outward from the annular wall 13. In this case, the outer periphery of the O-ring 17 is
Of the O-ring 17 is 40 times the cross-sectional diameter d of the O-ring 17.
６０60%, preferably about 50%. When the O-ring 17 is fitted in the fitting groove 16, the outer diameter D ₁₇ of the O-ring 17 is equal to that of the guide wall 15.
Of smaller than the outer diameter _{D 15 (D 17 <D 15} ) are formed.
However, the diameter D ₁₇ of the outer circumference of the O-ring 17 is greater than the inner diameter D ₆ of the inner circumferential wall 6 of the container 1 (D _17> D ₆₎ are formed. The outer diameter D ₁₇ of the O-ring 17 fitted in the fitting groove 16 is formed smaller than the inner diameter D ₇ of the inner peripheral wall 7a of the fitting portion 7 formed in the opening 2 of the container 1 (D
₁₇ <D ₇ ).

For this reason, when closing the opening 2 of the container 1 with the lid 10, as shown in FIG. 6, the guide wall 15 of the lid 10 slides on the inner peripheral wall 7 a of the fitting portion 7 to guide the container. At this time, the outer periphery of the O-ring 17 is prevented from contacting the inner peripheral wall 7a of the fitting portion 7. Since the O-ring 17 is made of an elastic member such as rubber, when the cover 10 is inserted into or taken out of the opening 2 of the container 1, the fitting portion 7 of the container 1 is used.
If the O-ring 17 is guided by the guide wall 15 to prevent the O-ring 17 from coming into contact with the inner peripheral wall 7a of the fitting portion 7, the lid 10 may be detached. Becomes extremely easy.

The sealing property between them is maintained. Therefore, it is possible to reliably prevent the cooking material or liquid in the container 1 from leaking out during cooking.

In this case, when the engagement projections 19 formed on the lid 10 are located in the vertical groove 3aa and the horizontal groove 3ab in the engagement grooves 3 on the container 1, the O-ring 17 is inclined. It does not reach the wall 7b, that is, the O-ring 17
Is in a loose fitting state without contacting the inner peripheral wall 7a of the fitting portion 7,
The engagement projections 19, 19 are provided at the engagement portions 3b at the back of the engagement grooves 3, 3,
When pushed into 3b, the O-ring 17 is pressed against the inclined wall 7b. Therefore, the lid 1
0 does not reach the normal closing position, and in the process of rotating operation, the O-ring 17 is in a loosely fitted state with the inner peripheral wall 7a of the fitting portion 7, so that the frictional resistance of the O-ring 17 is not generated.

The other operation plate 79 of 5 pushes down the lifting body 90. Accordingly, one operation plate 78 of the operation body 75 is separated from the operation element 71 of the switch 70. Therefore, in this state, the operating body 80 provided on the ridge 41a of the upper case 41
Is pressed down, and the operation button 81, the button axis 81a, the button axis 81a,
Even if the operating frame 83 is pushed down via the operating rod 82, the one operating plate 78 of the operating body 75 does not reach the operator 71 of the switch 70, so that the operator 71 cannot be pushed down. Therefore, the contact of the switch 70 is not closed.

A power supply cord 95 is led out of the joint between the upper case 41 and the lower case 42. The protector portion 96 of the power cord 95 has a mounting groove 96a formed in the protector portion 96 and the upper case 41 and the lower case 4
It is fitted and fixed between the two opening edges. An inner end of the power cord 95 is connected to the switch 70, and a plug 97 to be inserted into a power supply socket is attached to an outer end.

Next, the assembly of the main body 40 configured as described above will be described. First, the bearing 49 and the bearing 54 are attached to the mounting frame 47 in advance, and after inserting the shaft 49 having the bevel gear 53 attached to one of the bearings 49, the large-diameter pulley 51 is attached, and the concave coupling 61 is attached to the other bearing 54. The shaft portion 54 provided with the bevel gear 59 having the above is attached. Similarly, an electric motor 46 having a small-diameter pulley 48 is mounted on the mounting frame 47, and a belt 52 is stretched over the large-diameter pulley 51 and the small-diameter pulley 48.

Further, the support base 66 on which the switch 70 is mounted is fixed to the mounting boss 65 using screws 67.
Next, the push-up body 90 is fitted into the fitting hole 44. The button shaft 81a of the operation button 81 is inserted into the through hole 41b of the upper case 41.
And the upper end of an operating rod 82 having an operating plate 75 and a torsion coil spring 87 attached to its lower end in advance. Thus, the operating body 80 is attached to the upper case 41.

Next, the fitting edge 4 of the lower case 42
2d is fitted into the fitting portion 41b of the upper case 41, and the two cases 41 and 42 are connected by the screw 41d. Thereby, the main body 40 is assembled. In addition, both cases 41, 4
2 are combined, one of the operation plates 78 of the operation plate 75
While being opposed to the operating element 71 of the switch 70, the other operating plate 79 is opposed to the upper end of the push-up body 90, and the other operating plate 79 is placed at the upper end of the push-up body 90 by the urging force of the torsion coil spring 87. The pressing body 90 is pressed downward.

When connecting the two cases 41 and 42, the power supply cord 95 is mounted by fitting the mounting groove 96a provided in the protector portion of the power supply cord 95 into the edge of both cases.

Next, the cooking device A constructed as described above
The operation of will be described.

First, the rotating body 20 is fitted in the container 1 by fitting the bearing 34 to the shaft 5 provided on the container bottom 3, and then the object to be cooked for desired cooking is placed. Then, the convex coupling 23 of the rotating body 20 penetrates the through hole 11 of the lid 10, and the opening 2 of the container 1 is closed with the lid 10.

This closing is performed as follows. That is, the cover 10 is opposed to the fitting portion 7 of the container 1, and the engaging projections 19 are fitted into the engaging grooves 3. When the engaging projection 19 reaches the lower end of the vertical groove 3aa, the cover 10 is turned in the horizontal direction. Then, the engaging projection 19 is guided by the horizontal groove 3ab.
When the engaging projection 19 reaches the inner part of the horizontal groove 3ab,
Push in the lid 10.

In such an operation, when the engaging projections 19 of the cover 10 are located in the vertical groove 3aa and the horizontal groove 3ab of the engaging grooves 3, 3, the O-ring 1
7 is in a loosely fitted state without contacting the inner peripheral wall 7 a of the fitting portion 7. Therefore, since the O-ring 17 does not come into contact with the inner peripheral wall 7a of the fitting portion 7 at the initial stage of the insertion of the lid 10 and during the turning operation, frictional resistance of the O-ring 17 does not occur.
Good insertion and removal workability. When the engagement projections 19 are dropped into the locking portions 3b, the O-ring 17 is pressed against the inclined wall 7b and is elastically deformed, so that the seal between the lid 10 and the container 1 is sealed. Will be kept.

When the lid 10 is closed in the container 1 in this way, the main body 40 is placed on the lid 10. In this case, while the annular projecting wall 18 provided on the lid 10 is fitted into the fitting groove 43 formed in the lower case 42 of the main body 40,
Is placed on the lid 10. In this state, as described above,
As shown in FIG. 10, the push-up body 90 is pushed upward by the annular projecting wall 18 of the lid 10, so that the switch 70 can be closed by pushing down the operation body 80.
The concave coupling 61 of the main body 40 and the convex coupling 23 of the rotating body 20 are engaged with each other, and the annular flange 25 is a lower edge of an annular wall 10 a provided at an opening edge of the through hole 11 of the lid 10. Is located in the vicinity of

When the operation button 81 is depressed downward, the operation frame 83 is moved downward, so that the operation body 75 is rotated clockwise, the operator 71 of the switch 70 is depressed, and the contact of the switch 70 is contacted. Is closed. Therefore, the electric motor 46 is energized, and the electric motor 46 is driven. The drive of the motor 46 rotates the motor shaft 46d, and the bevel gear 59 is rotated via the small-diameter pulley 48, the belt 52, the large-diameter pulley 51, and the bevel gear 53. Therefore, the rotating body 20 is rotated via the concave coupling 61 and the convex coupling 23, the cutters 35a and 35b are rotated within the container 1, and the object to be cooked is cut, crushed, and stirred.

After the cooking is completed, the main body 40 is separated from the container 1 by removing the main body 40 from the lid 10,
0 is removed from the container 1, and the food in the container 1 is transferred to another container or the like as necessary. Then, the cooking operation is completed by washing the container 1, the rotating body 18 and the lid 10.

In a state where the main body 40 is detached from the lid 10, as shown in FIG.
The push-up body 9 is disengaged from the fitting groove 43.
0 protrudes and the operating body 7 is moved even when the operating body 80 is moved downward.
5 does not depress the operator 71 of the switch 70. Therefore, even if the operation button 81 is operated by mistake, the switch 70 is not closed, and the electric motor 46 is not driven. Therefore, the concave coupling 61 exposed on the lower surface of the main body 40 does not rotate, which is safe.

In the case of the above embodiment, when the lid 10 is attached to and detached from the container 1, the lid 10 is rotated, but the outer diameter D ₁₇ of the O-ring 17 is since is formed smaller than the inner diameter D ₇ of the inner peripheral wall 7a of the formed fitting portion _{7 (D 17 <D 7)} , O -ring 17 is fitted portion 7 when inserting the lid 10 to the fitting portion 7 Does not come into contact with the inner peripheral wall 7a, so that the contact resistance is small, and the lid 10 can be easily rotated. Therefore, operability is good.

The outer diameter D ₁₇ of the O-ring 17 is larger than the inner diameter D ₆ of the inner wall 6 of the container 1 (D ₁₇ > D ₆ ).
The O-ring 17 is formed at the lower end of the fitting portion 7,
That is, when it reaches the inclined wall 7b, it hits the inclined wall 7b and is elastically deformed. Due to this elastic deformation, the O-ring 17 is pressed against the container 1, so that the lid 10 and the container 1 are sealed.

In this case, the O-ring 17 has an amount s by which the outer periphery of the O-ring 17 protrudes from the annular wall 13 of the lid 10.
Is formed so as to be 40 to 60%, preferably approximately 50% of the cross-sectional diameter d of the O-ring 17, and the O-ring 17 undergoes a sufficiently large elastic deformation.

The inclination of the inclined wall 7b on the side of the container 1 may be low due to molding errors and molding variations.
Is formed so as to be 40 to 60%, preferably approximately 50% of the cross-sectional diameter d, so that even if the inclined wall 7b is inaccurate with a low degree of accuracy, the inclined wall 7b can be securely adhered. Become. Therefore, a high sealing property is maintained, and the cooking material in the container 1 is reliably prevented from leaking during cooking.

On the outer surface of the annular wall 13 of the lid 10, a guide wall 15 formed with an outer diameter D ₁₅ smaller than the inner diameter D ₇ of the inner peripheral wall 7 a of the fitting portion 7 (D ₁₅ <D ₇ ). Since it is provided, the guide wall 15 is guided by the inner peripheral wall 7 a of the fitting portion 7 when the lid 10 is inserted into the fitting portion 7.
Therefore, even if the O-ring 17 does not come into contact with the inner peripheral wall 7a of the fitting portion 7, the lid 10 is guided by the guide action of the guide wall 15, and the lid 10 is inserted eccentrically, or the lid 10 is eccentrically inserted. The body 10 is prevented from tilting. For this reason, the O-ring 17 abuts on the inclined wall 7b almost uniformly over the entire circumference, and is elastically deformed almost uniformly, so that a good sealing action is achieved.

During the cooking as described above, the cooking ingredients are vigorously stirred in the container 1.
The annular flange 2 having a diameter larger than the through hole 11 of the lid 10
Since the annular flange 25 is provided near the through-hole 11, the annular flange 25 reliably prevents the cooking material from jumping out of the through-hole 11 to the outside. Therefore, the outer surface of the lid 10 or the concave coupling 61
The cooking material does not adhere to the convex coupling 23 and the lower surface of the main body 1 or the like. Therefore, contamination of the main body 1 caused by the adhesion of the cooking material, that is, the object to be cooked or the like is prevented, and there is no need to clean the main body 1, and there is no adverse effect on the electric motor 46 that may occur due to the contamination. Can be prevented.

Further, the lid 10 is formed with the annular wall 10a projecting below the opening edge of the through hole 11, that is, inwardly of the container 1, so that the cooking material is reliably prevented from jumping out.

The annular flange 25 provided on the rotating body 20 can be used as a knob when the rotating body 20 is attached to and detached from the container 1, and the annular flange 25 is formed in a circular plate shape. As a result, it is easy to pick and the operability of attaching and detaching the rotating body 20 is good.

Further, a plurality of ribs 26 are formed on the outer surface of the shaft portion 22 at a position higher than the annular flange 25 on the rotating body 20, and the ribs 26 are formed in the through holes 11 of the lid 10. As a result, the food that has entered the through hole 11 from inside the container 1 will be blown off by centrifugal force due to the rotation of the ribs 26... Due to the rotation of the rotating body 20, and will pass through the through hole 11. Is prevented. Therefore, the object to be cooked is prevented from scattering to the outside.

When the main body 40 is detached from the container 1, as shown in FIG. 11, the main body 40 is separated from the lid 10 so that the push-up body 90 projects downward, and the operating body 75 is turned on by the switch 7.
When the main body 40 is removed from the container 1 in this state, the convex coupling 23 and the concave cup 23 are turned off. Since the ring 61 is engaged, the rotating body 22 that is rotating also tries to be pulled out together with the main body 40.

However, since the annular flange 25 of the rotating body 22 comes into contact with the annular protruding wall 10a formed in the through hole 11 of the lid 10, the convex coupling 23 and the concave coupling 61 are disengaged. 1 and does not jump out of the container 1.

At this time, when the annular flange 25 of the rotating body 22 comes into contact with the lid 10, the lid 10 is lifted and tends to be separated from the container 1.
Since it is locked by the engagement of the engagement groove 9 with the engagement groove 3, it does not come off from the container 1 unless it is rotated, so that the lid 10 does not come off from the container 1 carelessly. Therefore, the rotating body 20 reliably remains in the container 1 closed by the lid 10. Therefore, the rotating body 20 rotating by inertia remains in the container 1 and does not jump out of the container 1, and
It is safe because only 0 is removed.

The rotating body 20 remaining in the container 1 has a bearing 34
The fitting depth H of the annular flange 25 and the cover 10
(H> A), so that even if the annular flange 25 hits the lid 10, the bearing 3
4 does not come off the support shaft 5. Therefore, the lower end of the rotating body 20 is supported by the bearing 34 and the support shaft 5 and the upper end is supported by the through-hole 11 of the lid 10 via the rib portion 26. It is supported while maintaining. As a result, the rotating body 20 does not turbulently rotate in the container 1.

[0084]

As described above, according to the first aspect of the present invention, since the rotating body is provided with the annular flange portion having a diameter larger than the through hole on the lid side, the object to be cooked in the container is not cut by the cutter. Even if it is agitated and scatters upward from the through hole,
The annular flange prevents jumping out ,
Since multiple ribs are formed on the rotating body,
So that the food adhered to the ribs is blown off by centrifugal force
The food to be intruded into the through hole is returned to the container.
However, it can be prevented from being scattered outside . Therefore, the object to be cooked is prevented from adhering to the main body or the like outside the through hole, and the effects are obtained such that these external things are not stained and the trouble of cleaning these can be saved. In addition, the annular flange can be used as a knob when the rotating body is detached or attached, thereby improving operability.
