Description

  The present invention relates to an attachment for stirring a hand mixer mainly used at home, and more particularly to an attachment suitable for making mayonnaise, dressing or soup.

  In the conventional attachment for stirring, as described in Patent Document 1 and Patent Document 2, an outer stirring blade that has a plurality of semi-annular stirring blades and rotates on the outermost side of rotation, and more than that, An attachment having an inner stirring blade that performs a stirring action inside is disclosed. In Patent Document 1, the stirring blade rotating outside and the stirring blade rotating inside the region are not formed in the same stirring blade, but rotated 90 degrees after the stirring blade rotating outside passes. After that, another stirring blade passes through the inside. Therefore, the outer stirring blade and the inner stirring blade do not cooperate when passing through a certain position, and the outer and inner stirring blades shift the time with respect to the certain position. Each has its own stirring action. In this way, since the outer stirring and the inner stirring are not performed almost simultaneously at a certain position, it is not possible to generate a complicated liquid flow that is possible due to the cooperation of the two stirring blades. A good stirring action cannot be obtained.

  In Patent Document 2, since the inner stirring blade is attached to the inner side of the outer stirring blade, the outer stirring blade and the inner stirring blade simultaneously cooperate to perform a stirring action. And both ends of the inner stirring blade are respectively coupled to the rotation shaft. Since the attachment used for a general hand mixer has a stirring blade and a rotating shaft made of metal, at least the upper end of the stirring blade is attached to the rotating shaft by welding with a special metal fitting. It takes time to install. Both ends of the inner stirring blade of Patent Document 2 are coupled to the rotation shaft, and when the stirring blade and the rotation shaft are formed of metal, welding work using metal fittings is performed at two locations above and below the inner stirring blade. It is necessary and very time consuming.

  An object of the present invention is to provide an attachment that is efficient in stirring by the cooperation of an outer stirring blade and an inner stirring blade, and that does not require time and effort to attach or form the inner stirring blade.

The present invention includes a rotating shaft connected to a driving device and a plurality of stirring blades attached to the rotating shaft, wherein at least one stirring blade is formed in a semi-annular shape, and the stirring blade includes the stirring blade. The auxiliary stirring blade formed by bending one portion divided into two by the longitudinally extending opening formed on the inner side, and a semi-annular main portion which is the remaining portion of the auxiliary stirring blade and a stirring blade, a attachment hand mixer with, the stirring blade is formed bent in a semi-circular forming a U-shaped katakana, has a lower surface forming a plane, the auxiliary agitation blade is, the stirring blade The opening extends to the vicinity of the lower end of the stirring blade so as to be able to rise vertically from the lower surface portion forming a plane, and passes through the straight portion extending vertically to the main stirring blade while being bent in the middle. lead to Has two other parts also extending perpendicularly straight portion which is divided into the opening extending in the longitudinal direction, a configuration in which a and its other portions and the auxiliary agitation blade passages of the stirring object is formed.

The present invention includes a rotating shaft connected to a driving device and a plurality of stirring blades attached to the rotating shaft, wherein at least one stirring blade is formed in a semi-annular shape, and the stirring blade includes the stirring blade. The auxiliary stirring blade formed by bending one portion divided into two by the longitudinally extending opening formed on the inner side, and a semi-annular main portion which is the remaining portion of the auxiliary stirring blade and a stirring blade, a attachment hand mixer with, the stirring blade is formed bent in a semi-circular forming a U-shaped katakana, has a lower surface forming a plane, the auxiliary agitation blade is, the stirring blade The opening extends to the vicinity of the lower end of the stirring blade so as to be able to rise vertically from the lower surface portion forming a plane, and passes through the straight portion extending vertically to the main stirring blade while being bent in the middle. lead to Has two other parts also extending perpendicularly straight portion which is divided into the opening extending in the longitudinal direction, the passage of the stirred material is formed by the other lateral portion and the auxiliary agitation blade of. Since the auxiliary stirring blade extends inward from the main stirring blade, the main stirring blade and the auxiliary stirring blade pass through a certain position almost simultaneously during rotation of the stirring blade. Therefore, since this stirring is the stirring by the cooperation of the two stirring blades of the main stirring blade and the auxiliary stirring blade, the portion surrounded by both stirring blades is compared with the case of stirring by one stirring blade. A complicated flow can be generated in the liquid, and the liquid can be efficiently stirred.

Moreover, since this invention is the above structures , the auxiliary stirring blade exists in the at least lower part of the main stirring blade. For example, chopped onions are added when making dressings, and corn is added to milk when making corn soup, in which case the onions and corn sink to the bottom of the container. Therefore, if there is an auxiliary stirring blade in the lower half of the main stirring blade, the onion or the like that is submerged in the bottom of the container can be efficiently stirred. In addition, even when this attachment is used to simply mix the objects to be stirred, the main stirring blade and the auxiliary stirring blade can be efficiently stirred together.

FIG. 1 is a perspective view of the present invention. FIG. 2 is a side view of the present invention. FIG. 3 is a central sectional view.

  The attachment 1 includes a rotating shaft 2 connected to a driving device and four stirring blades 3, 3, 4, and 4. Opposing stirring blades 3 and 3 are formed by bending one elongated metal plate into an annular shape. When the upper end portions 5 and 5 of the stirring blades 3 and 3 are fixed between the connecting fittings 6 and 7 attached to the lower end portion of the rotating shaft 2, the stirring blades 3 and 3 are attached to the rotating shaft. The other opposed stirring blades 4 and 4 are also attached to the rotary shaft 2 in the same manner as the stirring blades 3 and 3. The lower end portion 13 of the stirring blades 3 and 3 and the lower end portion 14 of the stirring blades 4 and 4 overlap each other and intersect in a cross shape, and are fixed by welding at the intersecting portions.

  Next, the configuration of the stirring blades 3, 3, 4 and 4 will be described. Since the configuration of the four stirring blades is the same except for the intersection of the lower end portions, only one stirring blade 3 will be described below. To do. The agitating blade 3 corresponds to one of the two agitating blades 3 and 3 formed by bending an elongated metal plate into an annular shape. The stirring blade 3 includes a main stirring blade 8 formed in a semi-annular shape and an auxiliary stirring blade 9 formed integrally with the main stirring blade 8. In the method of forming the stirring blade 3 from an elongated metal plate, before the elongated metal plate is bent into an annular shape, first, two elongated openings 10 and 11 having the same length extending in the longitudinal direction are formed. By forming the openings 10 and 11, the rib 12 is formed between the lower end of the upper opening 10 and the upper end of the lower opening 11. In addition, the stirring blade 3 is divided into two parts by the openings 10 and 11 and extends in parallel, and finally, one of the portions becomes the auxiliary stirring blade 9. In this way, the original shape of the semi-annular stirring blade 3 is formed by bending the elongated metal plate having the openings 10, 10, 11, 11 into an annular shape, but at the same time, the lower opening 11 is formed. The auxiliary agitating blade 9 is formed by pressing one of the parallel extending portions separated by bulge inwardly. When the auxiliary stirring blade 9 is formed, the lower opening 11 which was originally in the shape of a long hole is changed in shape as shown in FIG. 1 or FIG. A small passage 15 for an object to be stirred is formed between the blades 9. Thus, in this embodiment, the main stirring blade 8 and the auxiliary stirring blade 9 constituting the small passage 15 are displaced in the radial direction of the stirring blade 3 and also in the rotational direction thereof. . In this way, the auxiliary stirring blade 9 is formed, and the remaining portion becomes the main stirring blade 8 and the stirring blade 3 is formed.

Since the main stirring blade 8 of the stirring blade 3 is bent and formed in a semicircular shape having a U-shape of Katakana, the upper surface portion 16 and the lower surface portion 17 of the stirring blade 3 are respectively flat. The upper opening 10 of the stirring blade 3 extends from the rib 12 of the stirring blade 3 to the vicinity of the upper end portion 5, and the lower opening 11 extends from the rib 12 of the stirring blade 3 to the vicinity of the lower end portion 13. Yes. The auxiliary stirring blade 9 rises vertically from the lower surface portion 17 of the stirring blade 3 and extends to the vicinity of the rib 12 while being bent halfway. The distance between the vertically extending straight portion of the auxiliary stirring blade 9 and the vertically extending straight portion of the main stirring blade 8 is about the distance between the rotation center line and the vertically extending straight portion of the main stirring blade 8. 30%. The height width of the auxiliary stirring blade 9 is about 40% of the height width of the main stirring blade 8. Thus 15 is defined. In addition, although the height width of the stirring blade 3 is about 58 mm and the distance between a pair of stirring blades 3 and 3 is about 44 m, of course, this invention is not limited to these numerical values.

  The attachment 1 of this embodiment is suitable for making mayonnaise, dressing, and soup, in addition to simply mixing the materials to be stirred. For example, in the case of making mayonnaise, first, several egg yolks, vinegar, salt and pepper and a small amount of oil are added and stirred with an attachment. Egg yolk is highly viscous and has a coating on its surface, making it difficult to blend in with other materials. However, in this embodiment, since the small passage 15 for the object to be stirred is in the lower half of the stirring blade 3, the main stirring blade 8 and the auxiliary stirring blade 9 on the inner side of the egg yolk passing through the passage 15 are separated. At almost the same time, the egg yolk can be cut in two places at once so that it can be immediately blended into other ingredients and can be efficiently stirred. And when they are well mixed, add oil little by little while stirring. In this case, the main stirring blade 8 and the auxiliary stirring blade 9 cooperate to efficiently and uniformly disperse the oil added little by little in one place. When the total amount of oil has been added and mixing is continued, the material to be stirred is emulsified, and finally vinegar is added and stirred. When almost the whole amount of the material is put into the container and emulsified, the entire stirring blade 3 is caught in the object to be stirred, but the auxiliary stirring blade 9 is only in the lower half of the stirring blade 3 and the stirring blade 3 Therefore, the resistance received from the object to be stirred can be suppressed accordingly. Also, when making a dressing with chopped onions or when making corn soup with granular corn, the onion and corn sinking under the object to be stirred are brought into the main stirring blade 8 and the auxiliary stirring blade 9 inside thereof. Since these two blades are stirred almost simultaneously, stirring can be performed more efficiently than when stirring with one stirring blade. Moreover, when these dressings and corn soup are stirred until they are in a state close to emulsification, there is no auxiliary stirring blade 9 in the upper half of the stirring blade 3, so that, similarly to making mayonnaise, The resistance received can be suppressed.

  In addition, this invention can take a various aspect based on the structure mentioned above. For example, the ratio of the height width of the auxiliary stirring blade 9 to the height width of the stirring blade 3 may be a ratio between 20% and 80%, preferably 40% as in the embodiment, 30 The value is between 60% and 60%. Further, although the auxiliary stirring blade 9 bulges inward, the main stirring blade 8 corresponding to the section in which the auxiliary stirring blade 9 extends may also be bulged inward. However, the bulging degree of the main stirring blade 8 does not exceed the bulging degree of the auxiliary stirring blade 9. In this way, when the main stirring blade 8 in the portion is bulged inward, the main stirring blade 8 is close to the bottom of the container when used in a container such as a bowl in which the inner diameter of the stirring container decreases toward the bottom. There is an effect that it becomes difficult to hit the inner surface of. Further, the degree of bulging inside the auxiliary stirring blade 9 may be different for each stirring blade. In that case, the rotating position of each auxiliary stirring blade is different in the radial direction, and the portion close to the bottom of the container can be uniformly stirred, so that the stirring efficiency is increased.

Since the stirring blade 3 has the auxiliary stirring blade 9 in addition to the main stirring blade 8, the stirring blade 3 can be efficiently stirred, and the height width of the auxiliary stirring blade 9 is smaller than the height width of the main stirring blade 8. By doing this, it is possible to suppress the resistance received from the object to be stirred when the object to be stirred is emulsified during stirring.
