The cooking mixer for supplying silver according to the preferred embodiment of the present invention includes a container 110 for containing foodstuffs to be grinded, a power part 130 for generating power, a connection part 120 for separately connecting the container 110 to the power part 130, and a rotating body 20 connected to a rotary shaft of the power part 130 in a state where the connection part 120 is interposed between the connection part 120 and the rotating body 20, and having a plurality of blades 22 for grinding the foodstuffs. The cooking mixer according to the preferred embodiment of the present invention has the same fundamental configuration as the prior art, and so, a detailed description of the configuration is omitted.
The cooking mixer for supplying silver according to the preferred embodiment of the present invention includes the rotating body 20 having a plurality of the mixer blades 22 for grinding foodstuffs contained in the container 110, and a screw 25 and a washer 27 for coupling the rotating body 20 to the rotary shaft 30. The mixer blades 22 are formed symmetrically at the outer edges of the rotating body 20, and each mixer blade 22 has at least one insertion space 24 formed thereon.
A silver body 23 is mounted in the insertion space 24 by one of general methods, such as thermofusion.
The insertion space 24 may be in a form of a hole as shown in FIG. 4(a), or in a form of a recess as shown in FIG. 4(b). It is preferable that the insertion spaces 24 be formed on both sides of the blade when the insertion space 24 is in the form of the recess.
Furthermore, the shape of the insertion space 24 is not restricted to the above proposed shapes, but can have various shapes.
Moreover, the screw 25 and the washer 27 are made of silver or a material plated with silver. Preferably, a stainless steel screw 25′ which is generally used is plated with silver as shown in FIG. 3, to provide the screw 25 with sufficient strength. The screw 25 is inserted into a screw hole 26 and coupled with the rotary shaft 30, and the washer 27 made of silver is fit between the screw and the rotating body 20. By the above configuration, the cooking mixer according to the preferred embodiment of the present invention can supply more silver to foodstuffs which are grinded.
Meanwhile, the insertion space 24 formed on the mixer blade 22 has a screw thread portion 24a formed on the inner periphery thereof so as to enhance a binding force between the insertion space 24 and the silver body 23. That is, a portion of the silver body 23 fits between grooves of the screw thread portion 24a formed on the inner periphery of the insertion space 24, whereby the binding force between the silver body 23 and the insertion space 24 is increased. Here, the insertion space 24 has a circular shape, but the shape of the insertion space 24 is not restricted to the above and may be formed in various shapes, such as an elongated shape, an elliptical shape or a rectangular shape.
The silver body 23 can be mounted on the insertion space 24 by thermofusion, compression molding or other methods. In FIG. 6, the silver body 23 is mounted on the insertion space 24 by compression molding.
That is, an upper mold 40 having a concave portion formed on the bottom surface thereof for forming a projection 23a of the silver body 23 is located at one side of the mixer blade 22 having the insertion space 24, and a lower mold 45 having a flat upper surface is locate at the other side of the mixer blade 22. After that, the silver body 23 of a predetermined length is inserted into the insertion space 24, and the upper mold 40 is lowered, whereby the projection 23a having a diameter larger than that of the insertion space 24 is formed at the side of the mixer blade 22.
That is, when the upper mold 40 is lowered to the state where the silver body 23 of the predetermined length is inserted into the insertion space 24, a strong compression force acts between the upper mold 40 and the lower mold 45, and then, a portion of the silver body 23 is fit into the grooves of the screw thread 22a formed on the inner periphery of the insertion space 22 so as to provide strong fixing force while the silver body 23 is compressed by the compression force.
At this time, as shown in FIG. 5, to form the projections 23a of the silver body 23 at both sides of the mixer blade 22, the lower mold 45 has the same concave portion as the upper mold 40. As described above, when the projections 23a of the silver body 23 is formed at both sides of the mixer blade 22, since a contact area between the food and the silver body 23 is increase, silver content of the food is increased.
Finally, the strong compression force acts between the upper mold 40 and the lower mold 45 in a state where the silver body 23 is inserted into the insertion space 24 of the mixer blade 22, the silver body 23 which is relatively soft is transformed, and so, a portion of the silver body 23 is fit into the grooves of the screw thread 24a so as to provide strong binding force.
As described above, the screw thread 24a is formed on the inner periphery of the insertion space 24 in order to improve binding force between the insertion space 24 and the silver body 23, but instead of the screw thread 24a, a slit 24b which has a diameter larger than the inner diameter of the insertion space 24 may be formed along the inner circumference oft the insertion space 24.
In this case, since a portion of the silver body 23 is inserted into the slit 24b when the silver body 23 is compressed, the binding force between the silver body 23 and the insertion space 24 is increased so as to improve durability.
Furthermore, without regard to the method that the screw thread is formed on the inner periphery of the insertion space 24 or the method that the slit is formed on the inner periphery of the insertion space 24, the insertion space 24 is formed in a hole, and the projections 23a of the silver body 23 mounted in the insertion space 24 can be respectively formed at the upper and lower sides of the mixer blade 22. Of course, the insertion space 24 is formed in a groove type, and the projection 23a of the silver body 23 mounted in the insertion space 24 can be formed only at the upper side of the mixer blade 22.
As described above, the preferred embodiment of the present invention can firmly fix the silver body 23 by forming the screw thread 24a or the silt 24b on the inner periphery of the insertion space 24 formed on the mixer blade 22 of the cooking mixer 200, thereby improving durability to prevent easy separation of the silver body 23 from the mixer blade 22. Moreover, the preferred embodiment of the present invention can increase silver intake into a human body by increasing silver content inside the food by maximizing a contact effect between the food and the silver body during the food grinding process since the projection 23a of the silver body 23 is projected to the outside from the surface of the mixer blade 22.
Additionally, the cooking mixer for supplying silver according to the preferred embodiment of the present invention naturally supplies silver to the grinded food, thereby helping the user to regularly take silver and detect poisonous matters contained in the food.
Moreover, the cooking mixer for supplying silver according to the preferred embodiment of the present invention can increase silver intake into the human body by increasing silver content inside the grinded food by raising a contact effect between the food and the silver body since a portion of the silver body projects from the surface of the mixer blade, and prevents separation of the silver body in spite of a long-term use since the silver body is firmly fixed on the mixer blade.
While the present invention has been described with reference to the particular illustrative preferred embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the preferred embodiments without departing from the scope and spirit of the claims.
