Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mixer that cuts and stirs food contained in a bottle using a cutter rotating at the bottom of the bottle.

[Conventional technology]

BACKGROUND OF THE INVENTION Mixers for cutting and stirring food for use as cooking ingredients are widely used in general households, cafeterias, and the like.

Figure 5 is a sectional view of a conventional mixer;
The figure is a perspective view of the upper part of the main body, FIG. 7 is a sectional view of the bottle holder, and FIG. 8 is a bottom view of the bottle holder. In these figures, a motor (not shown) is housed in a cylindrical body 1 placed on a table or the like, and a motor shaft (not shown) that protrudes from the center of the top surface of the body 1 has a motor shaft that protrudes from the top surface. A disc-shaped joint 4 having a plurality of locking pieces 2 and a plurality of blades 3 protruding from the lower surface is pivoted. Also,
On the upper surface of the main body 1, a plurality of locking pins 5 and a plurality of protrusions 6 are alternately protruded at positions dividing the outer circumferential portion into a plurality of equal parts in the circumferential direction. On the other hand, the whole code is 7
The bottle assembly shown in is equipped with a bottle holder 8 formed into a cylindrical shape with a bottom, and a plurality of locking plates 9 are protruded from the inner circumferential surface of the bottle holder 8 at positions dividing the circumferential direction into a plurality of equal parts. There is. Reference numeral 10 denotes a rotary shaft rotatably supported by a central bearing part of the bottle holder 8 via a bush 11, and the upwardly projecting part of the rotary shaft 10 has shafts arranged vertically alternately at positions equally divided in the circumferential direction. A cutter 12 having a blade body bent in a direction is fixed to the cutter 12, and a disc-shaped joint 14 provided with a plurality of locking pieces 13 protruding from the lower surface is attached to the downwardly protruding part.
is screwed and fixed to the threaded part. Reference numeral 15 denotes a cylindrical bottle made of a transparent material such as transparent plastic, the lower end of which is screwed into the threaded part of the bottle holder 8 via a packing 16, and the upper end opening is screwed into the threaded part of the bottle holder 8. It includes a lid 17 that opens and closes, and a handle 18 for gripping.

With the above configuration, when the bottle assembly 7 is placed on the main body 1, the relative positions of these are regulated in the height direction by the bottom surface of the bottle holder 8 and the protrusion 6, and the position of the bottle holder 8 is regulated in the height direction. It is regulated in the radial direction by the inner surface and the outer surface of the locking plate 5, and in the circumferential direction by the side surface of the locking plate 5 and the side surface of the locking plate 9. Then, open the lid 17, put food into the bottle 15, and rotate the motor.
The cutter 12 is rotated by engagement of the locking pieces 13, 2 of the upper and lower joints 14, 4, and the food is cut and stirred. When the blades 3 rotate integrally with the rotation of the motor, the outside air sucked in from below the main body 1 passes through the inside of the motor and is discharged from the gap between the bottom end of the bottle holder 8 and the top surface of the main body 1, causing the motor to The heat generated by the rotation of is cooled down. Since the bottle 15 is made of a transparent material, the stirring state of the food can be visually observed from the outside.

[Problem that the invention attempts to solve]

However, in the conventional mixer configured in this way, the gasket 16 for preventing water leakage from the bottle 15 is inserted between the bottle 15 and the bottle receiver 8, which increases the number of parts and increases the cost. There was also the problem that it was easy to lose it. That said, bottle 15 and bottle holder 8
Since the bottle 15 is made of a transparent material, even the bottle holder will be transparent, and as a result, a person driving while looking through the food from outside the bottle 15 will be able to see through the bottle 15. There was a problem that not only the joints 4 and 14 rotating in the bottle holder 8 were visually observed, giving a sense of danger, but also the thickness of the locking plate 9 was visually observable, resulting in an unsightly appearance. Further, since the protrusion 6 was provided to provide a gap for cooling the motor, this protrusion appeared when the bottle assembly 7 was removed, making it unsightly and posing a problem in terms of cleanability. Furthermore, since the joint 4, which is a rotating body, protrudes from the top surface of the main body 1 and its surrounding area is open, it is extremely dangerous if the motor is accidentally rotated with the bottle assembly 7 removed.

The present invention was developed in view of the above points, and the purpose is to provide a mixer that has a small number of parts, can be provided at low cost, has a good appearance, is safe, and has excellent cleanability. There is.

[Means for solving problems]

In order to achieve such an objective, the mixer according to the present invention includes a transparent bottle assembly in which a bottle holder is integrally formed, a main body on which this bottle assembly is placed, and a rotating part that protrudes from the upper surface of this main body. A non-transparent annular pedestal is provided on the upper surface of the main body, which is substantially the same height as the rotating body and is substantially concentric with the bottle holder inside the bottle holder.

[Effect]

When the motor inside the main unit is rotated, the cutter rotates, and the rotating body protruding from the top of the main unit also rotates.
Since this rotating body is surrounded by a non-transparent annular stand,
Even if the bottle holder is transparent, the rotating body cannot be seen from outside the bottle.

〔Example〕

1 to 4 show an embodiment of the mixer according to the present invention, FIG. 1 is a sectional view thereof, FIG. 2 is a perspective view of the upper part of the main body, FIG. 3 is a sectional view of the bottle holder, and FIG. FIG. 4 is also a bottom view of the bottle holder. In these figures, a motor (not shown) is housed in a cylindrical main body 21 that is placed on a table or the like, and a motor shaft that protrudes from the center of the top surface of the main body 21 has a motor shaft that protrudes from the top surface. A plurality of locking pieces 22 and a plurality of blades 2 protruding from the lower surface.
A disc-shaped joint 24 as a rotating body having a rotary member 3 and 3 is pivotally attached. On the upper surface of the main body 21, the main body 21
The locking piece 22 has a concentric annular shape with a diameter slightly smaller than that of the locking piece 22.
A non-transparent annular base 25 that is approximately the same height as the upper end of the joint 24 surrounds the entire joint 24 including the locking piece 22 and projects integrally therewith. On the upper surface of this annular base 25, a plurality of locking pins 26 as locking pieces protrude closer to the center than the outer peripheral surface of the annular base 25 at positions that divide the annular base 25 into a plurality of equal parts in the circumferential direction. It is set up. Note that the annular stand 25 is cut out at one location so that the inside and outside are communicated with each other.

On the other hand, the bottle assembly, which is designated as a whole by reference numeral 27, includes a bottle 28 formed into a cylindrical shape using transparent plastic as a permeable material, and a cylindrical bottle holder 29 with a bottom that is integrally molded with the bottle 28 from transparent plastic. A rotary shaft 30 is rotatably supported on the center bearing portion of the bottle holder 29 via a bush 31. 32 is a cutter fixed to the upper protrusion of the rotating shaft 30, and has a plurality of cutters bent vertically alternately at positions dividing the rotating shaft 30 into a plurality of equal parts in the circumferential direction. We are prepared. Further, a plurality of locking pieces 33 that engage with the locking pieces 22 are provided on the downwardly protruding portion of the rotating shaft 30.
A joint 34 equipped with a motor is pivotally mounted, and the joint 34 and the cutter 32 are configured to be rotated by being driven by the joint 24 which rotates together with the motor.
On the bearing plate 35 of the bottle holder 29 serving as the bottom plate of the bottle 28, a support ring 36 formed in a concentric double ring shape is integrally molded with the bottle holder 29 and protrudes downward, surrounding the joint 34. On the outer circumferential surface of the support ring 36, locking ribs 37 and 38, which serve as locking members of two different heights, are arranged in a radial direction at positions dividing the circumferential surface of the support ring 36 into a plurality of equal parts in the circumferential direction. They are protruded alternately. These locking ribs 37, 38
is a member that positions and restricts movement of the bottle assembly 27 in three directions: height direction, circumferential direction, and radial direction when the bottle assembly 27 is placed on the main body 21. Higher locking rib 3
The lower end of the annular base 25 is regulated by being supported by the upper end surface of the annular base 25. In this case, a gap communicating with the outside air is formed between the lower end of the bottle holder 29 and the upper surface of the main body 21. In addition, the plane of the higher locking rib 37 is regulated in the circumferential direction by abutting against the circumferential end surface of the locking pin 26, and the lower locking rib 38 is restricted in the radial direction. The radial end surface of the locking pin 26 is regulated by coming into contact with the inner circular arc surface of the locking pin 26. In addition, 39 is a lid that opens and closes the upper opening end of the bottle 28, and 40 is a lid that opens and closes the upper opening end of the bottle 28.
It is a handle for gripping.

With the above configuration, when the bottle assembly 27 is placed on the main body 21, the bottle holder 29 is placed on the main body 21 so that the bottle holder 29 and the annular stand 25 are substantially concentric. When the locking tab 26 is brought close to , the chamfered tip of the locking tab 26 is easily guided into the gap between the adjacent locking ribs 37, and the locking tab 26 engages with this gap. When the bottle assembly 27 is placed, the locking rib 3
7 comes into contact with the upper surface of the annular stand 25, so that the bottle receiver 29 is placed with a gap formed between the lower end of the bottle receiver 29 and the upper surface of the annular stand 25. As a result,
As shown by the two-dot chain line in FIG.
are located between adjacent locking ribs 37 to restrict movement of the bottle holder 29 in the circumferential direction, and the lower locking ribs 38 abut against the inner surface of each locking rib 26 to prevent the bottle holder 29 from moving in the circumferential direction. 29 is restricted from moving in the radial direction. That is, since the bottle assembly 27 is positioned in each direction, it will not fall over, and the joint 24 and the joint 34 will be concentric. The locking rib 3 is attached to the locking lever 26.
8 only abuts from the inside, and the outside is spaced apart from the inner circumferential surface of the bottle holder 29, so the outside surface visible from the outside will not be damaged.

After placing the bottle assembly 27 in this way, open the lid 39 and put food in the bottle 28, and rotate the motor to connect the upper and lower joints 34, 2
The cutter 32 is rotated by the engagement of the locking pieces 33 and 22 of No. 4, and the food is cut and stirred. When the blades 23 rotate integrally due to the rotation of the motor, the main body 21
The outside air sucked in from below passes through the motor and is discharged from the gap between the lower end of the bottle holder 29 and the upper surface of the main body 21, thereby cooling the heat generated by the rotation of the motor. In this case, providing a notch in the annular base 25 improves air circulation. Since the bottle 28 is made of transparent plastic, the stirring state of the food can be visually observed from the outside. Also bottle 28
By integrally molding the and bottle holder 29,
The bottle holder 29 is also transparent so that the inside can be seen visually, but the joint 24 that rotates with the motor is shielded by a non-transparent annular stand 25, and the upper end of the annular stand 25 has a conventional support ring 36. Since this continues, none of the rotating bodies can be seen from the outside and there is no sense of danger. Further, since the outer circumferential surfaces of the annular stand 25 and the locking tabs 26 that are visible from the outside do not come into contact with the inner circumferential surface of the bottle holder 29, they do not get dirty or damaged and always maintain a beautiful appearance.

[Effect of idea]

As is clear from the above description, according to the present invention, an annular stand having approximately the same height as the rotating body protruding from the top surface of the main body for placing the bottle assembly is placed on the top surface of the main body and the inner circumferential surface of the bottle holder. By protruding almost concentrically, the rotating body is shielded by the annular stand and cannot be seen from the outside, so it is comfortable without any sense of danger, and this also allows the bottle holder to be transparent. Since it is possible to integrally mold the bottle assembly with a transparent material, the structure is simplified, and there is no need for a seal between the bottle and the bottle holder, reducing the number of parts. Further, even if the motor is accidentally rotated with the bottle assembly removed, it is safe because the rotating body is surrounded by the annular base. Furthermore, since there is no protrusion on the periphery of the upper surface of the main body unlike in the conventional case, cleaning is easy.
