[0002]
[Prior art]
Conventionally, as shown in FIG. 10 and FIG. 11, known wholesale cutters for electric cookers (hereinafter simply referred to as wholesale cutters). In this wholesale cutter 1, a large number of wholesale blades 3 (see FIG. 11) for rubbing food such as radishes are formed on one side A of the disk portion 2. As shown in FIG. 10, a cylindrical boss 4 protrudes from one side B of the disk part 2 at the center of rotation of the disk part 2. A pair of mounting grooves 5 reaching the lower portion of the boss 4 are formed on the upper edge of the boss 4, and one thin shallow groove 6 extending across the mounting groove 5 is formed on the outer peripheral wall portion of the intermediate portion of the boss 4. A ring spring 7 is held in the shallow groove 6. The ring spring 7 is a rod-shaped member formed into a round shape. One end of the ring spring 7 is fixed to a hole (not shown) formed in the shallow groove 6 at an intermediate position between the pair of mounting grooves 5 and 5.
[0003]
The wholesale cutter 1 is detachably attached to a drive shaft 9 in a container 8 that stores the cooked food to be scraped off. The drive shaft 9 is rotated in a direction in which the food to be cooked is scraped off by a motor (not shown), and a pair of fixing protrusions 10 to be inserted into the grooves 5 and 5 of the boss 4 of the wholesale cutter 1 are formed on the outer peripheral surface of the drive shaft 9. Has been.
[0004]
When the boss 4 of the wholesale cutter 1 is mounted on the drive shaft 9, the fixing projection 10 of the drive shaft 9 is guided by the mounting grooves 5 and 5, and the ring spring 7 is deformed into an elliptical shape so that the mounting grooves 5 and 5 are fitted. Enter the back of. When the wholesale cutter 1 is removed from the drive shaft 9, if the wholesale cutter 1 is moved away from the drive shaft 9, the ring spring 7 is deformed again into an elliptical shape and comes out of the back of the mounting grooves 5 and 5. Reference numeral 11 denotes a container lid.
[0005]
[Problems to be solved by the invention]
However, since the conventional wholesale cutter for electric cookers has the wholesale blade 3 formed only on one side A of the wholesale cutter 1, it is possible to select the type of scraping as coarse or fine. It is necessary to prepare a plurality of wholesale cutters 1 according to the type of wholesale, which is not preferable because the number of parts increases and a large storage space is required.
[0006]
Therefore, it is conceivable to form the wholesale blades 3 on both surfaces of the wholesale cutter 1, but in order to integrally form the wholesale blade 3 on both surfaces A and B of the disc part 2, the orthogonal direction with respect to both surfaces A and B can be used. It is necessary to hit the mold. However, since the shallow groove 6 for attaching the ring spring 7 must be formed on the outer periphery of the boss 4 , it is necessary for the one side B of the disk portion 2 to enter and exit from a direction parallel to the one side B. That is, since it is necessary to form the shallow groove 6 for the ring spring 7 on the outer periphery of the boss 4 , it is difficult to form the wholesale blades 3 on both sides A and B of the disk portion 2. There was a problem that it was not possible to form both sides easily.
[0007]
The present invention has been made paying attention to such a problem, and an object of the present invention is to disclose a structure of a wholesale cutter for a cooker in which a wholesale blade can be formed on both surfaces of the wholesale cutter.
[0008]
