     Related Applications  
       [0001]     The present application is based on, and claims priority from, Korean Application Number 20-2005-0009292, filed Apr. 6, 2005, and Korean Application No. 20-2006-0001153, filed Jan. 13, 2006, the disclosures of which are hereby incorporated by reference herein in their entirety.  
         [0002]     2. Field of the Invention  
         [0003]     The present invention relates to a cooking mixer for supplying silver, and more particularly, to a cooking mixer for supplying silver, which can supply silver into foods grinded by a mixer by mounting a silver body on a mixer blade body having a plurality of blades.  
         [0004]     2. Background Art  
         [0005]     As shown in  FIG. 1 , a general cooking mixer  100  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.  
         [0006]     In a state where the foodstuffs to be grinded are contained in the container  110  of the cooking mixer  100 , the rotating body  20  is rotated by the power part  130 , whereby the blades  22  of the rotating body  20  grind and mix the foodstuffs. Therefore, the mixing cooker can pulverize nuts such as walnuts or peanuts into powder by grinding them, or crush out fruit juice by grinding fruits such as apples or pears.  
         [0007]     Meanwhile, silver has been widely used not only as noble metal but also as artistic materials or monetary materials, and also widely used as tableware materials since it has been informed that silver can detect poisonous matters and acts as an element helpful to a human body. Moreover, it has been informed that, when a person carries silver with him or her, it is of sovereign remedy in curing various mental diseases, such as epilepsy and convulsions, and women&#39;s diseases. Additionally, it has been also informed that silver serves to remove various foreign matters and pathogenic organs existing in a human body and recover injured or damaged tissues since it acts as antibiotics with no ill effect. In addition, folk remedies that people wash their eyes with mineral water can take effect since mineral water contains silver, silkworms which eat mulberry leaves are of sovereign remedy in invigoration and curing diabetes since the silkworms have a great deal of silver, and a plaster is also of sovereign remedy in swelling since it contains silver.  
         [0008]     However, since silverwares just have some functions of containing foods, decoration, and detection of poisonous matters, the silverwares have a limitation in providing actions helpful to a human body by regularly eating and taking silver ingredient.  
         [0009]     Meanwhile, Korean Utility Model Registration No. 226427 discloses a pot lid for supplying silver to foods, which can supply silver to foods during cooking. Moreover, Korean Utility Model Registration Nos. 378465 and 378466 respectively disclose cooking scissors and a kitchen knife with silver attached thereon, which can naturally supply silver to foods during cutting cooked foods or live foods such as live vegetables or live fishes before cooking the foods.  
         [0010]     However, the prior arts have a disadvantage in that it is difficult to apply the above technologies to foods to be grinded, for instance, when a user crushes out juice or chops foods.

         [0033]     The cooking mixer for supplying silver according to 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 present invention has the same fundamental configuration as the prior art, and so, a detailed description of the configuration will be omitted.  
         [0034]     The cooking mixer for supplying silver according to 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.  
         [0035]     A silver body  23  is mounted in the insertion space  24  by one of general methods such as thermofusion.  
         [0036]     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 referable that the insertion spaces  24  are formed on both sides of the blade when the insertion space  24  is in the form of the recess.  
         [0037]     Furthermore, the shape of the insertion space  24  is not restricted to the above shapes proposed in the present invention, but can be formed in various shapes, and it is also included in the scope of the present invention.  
         [0038]     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 , since the screw  25  has to have 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 present invention can supply more silver to foodstuffs which are grinded.  
         [0039]     Meanwhile, the insertion space  24  formed on the mixer blade  22  has a screw thread portion  24 a formed on the inner periphery thereof so as to enhance binding force between the insertion space  24  and the silver body  23 . That is, a portion of the silver body  23  is fit between grooves of the screw thread portion  24   a  formed on the inner periphery of the insertion space  24 , whereby binding force between the silver body  23  and the insertion space  24  is increased. Here, the insertion space  24  is in 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 and a rectangular shape.  
         [0040]     The silver body  23  can be mounted on the insertion space  24  by thermofusion, compression molding or other method.  FIG. 6  shows that the silver body  23  is mounted on the insertion space  24  by compression molding.  
         [0041]     That is, an upper mold  40  having a concave portion formed on the bottom surface thereof for forming a projection  23   a  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  lowers, whereby the projection  23   a  having a diameter larger than that of the insertion space  24  is formed at the side of the mixer blade  22 .  
         [0042]     That is, when the upper mold  40  lowers in the state where the silver body  23  of the predetermined length is inserted into the insertion space  24 , 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  22   a  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.  
         [0043]     At this time, as shown in  FIG. 5 , to form the projections  23   a  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  23   a  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.  
         [0044]     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  24   a  so as to provide strong binding force.  
         [0045]     As described above, the screw thread  24   a  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  24   a , a slit  24   b  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 .  
         [0046]     In this case, since a portion of the silver body  23  is inserted into the slit  24   b  when the silver body  23  is compressed, binding force between the silver body  23  and the insertion space  24  is increased so as to improve durability.  
         [0047]     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 type, and the projections  23   a  of the silver body  23  mounted into the insertion space  24  can be respective 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  23   a  of the silver body  23  mounted into the insertion space  24  can be formed only at the upper side of the mixer blade  22 .  
         [0048]     As described above, the present invention can firmly fix the silver body  23  by formed the screw thread  24   a  or the silt  24   b  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 an easy separation of the silver body  23  form the mixer blade  22 . Moreover, 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  23   a  of the silver body  23  is projected to the outside from the surface of the mixer blade  22 .  
         [0049]     Additionally, the cooking mixer for supplying silver according to the present invention naturally supplies silver into the grinded food, thereby helping the user to regularly take silver and detecting poisonous matters contained in the food.  
         [0050]     Moreover, the cooking mixer for supplying silver according to 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 is projected from the surface of the mixer blade, and prevent separation of the silver body in spite of a long-term use since the silver body is firmly fixed on the mixer blade.  
         [0051]     While the present invention has been described with reference to the particular illustrative 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 embodiments without departing from the scope and spirit of the present invention.
