FIG. 1 shows a side sectional view of an embodiment of a cooking device according to the prior art.
According to the cooking device shown in FIG. 1, the cavity 100 is included inside the main body 10. The cavity 100 constitutes a space in which the cooking object is heated. The cavity 100 is generally composed of a heat resistant material. Therefore, a metallic material may be used.

  The cooking device may include a heater 30, and if the heater 30 is included, the radiant heat generated thereby heats the object to be cooked. As shown in the figure, the heaters 30 can be configured in pairs on the upper and lower sides, but in some cases, can be configured in pairs on the left and right sides, and can be configured only on the lower side or the upper side.

  The cooking device is provided with a blower fan 41 and can convect heat generated by the heater 30. The blower fan 41 rotates around the rotation shaft 42 to form an air flow, and the formed air flow is transmitted to the inside of the cavity 100 through the vent hole 43 to promote a heat convection phenomenon.

  A door 20 may be provided in front of the cooking device and may further include a handle 21 for opening and closing the door.

  Hereinafter, various embodiments of the present invention will be described based on the above-described structure of the cooking device. However, the above-described structure of the cooking device is merely an example of various cooking devices, and is merely adopted on the basis of such a structure for convenience of explanation. Therefore, it can be said that the protection scope of the present invention is not limited to this.

First, the anodization reaction will be described in detail with reference to FIGS.
Anodization is an oxidation phenomenon that occurs during the anodic reaction. According to the anodic oxidation reaction, a process of growing an oxide or nitride film formed on a metal surface using an electrolytic reaction is performed. it can. In the anodic oxidation reaction, a microscopic change in the metal surface or a change in crystal structure can occur. An example of anodic oxidation will be described as follows.

  When a direct current is passed through the electrolytic solution, hydrogen is generated in the cathode metal, and oxygen is generated in the anode metal (aluminum Al, titanium Ti, zinc Zn, magnesium Mg, niobium Nb, etc.). Oxygen reacts with the anode metal to form a metal oxide film. In this process, the electrolyte solution finely dissolves the generated oxide film. At this time, if the dissolution rate and the formation rate of the oxide film are balanced, the electrolyte is applied to the anode metal surface. A large number of pores having a diameter of 10 to 150 nm are formed.

  If such pores are formed, the electrolyte and current can come into contact with the metal substrate present under the oxide film, and as a result, the oxidation formed by the spontaneous metal oxidation reaction. A film much thicker than the object can be formed. The oxide film formed by the above method is referred to as an oxide layer.

  On the other hand, the oxide layer has various physical properties depending on the process conditions. In general, the thicker the coating is formed, the lower the concentration of the electrolyte and the higher the current or voltage.

  If the anodic oxidation reaction proceeds, the anodic metal may be etched with a base solution to remove oxides present on the surface, desmutted with a weakly acidic solution, and insoluble material removed.

  Referring to FIG. 2, a process for causing an anodic oxidation reaction is shown in the first embodiment of the cavity of the cooking device according to the present invention. As shown in FIG. 2, the conducting wire 200 may be disposed inside the cavity 100 and the anodic oxidation reaction may proceed. The cavity 100 is made of a metallic material, and the conductive wire 200 is made of the same metallic material as the cavity 100. A cathode current is applied to the conducting wire 200, an anode current is applied to the cavity 100, and an electrolyte is added to the cavity 100 and the conducting wire 200, so that at least a part of the surface of the cavity 100 to which the anode current is applied. A porous oxide layer can be formed.

  As described above, the metallic material constituting the cavity 100 can be any one of aluminum Al, titanium Ti, zinc Zn, magnesium Mg, and niobium Nb.

  On the other hand, the entire cavity 100 may not be formed of the same single metallic material, and an anodizing reaction may proceed after forming a separate metal layer only on the cavity 100 surface. That is, after a treatment such that the metal layer is coated on the surface of the cavity 100 using a method such as vapor deposition, an anodizing reaction is caused on the metal layer to form a porous oxide layer. it can.

  FIG. 3 shows a process in which the porous oxide layer 113 is formed after the metal layer 112 is separately formed on the surface 111 of the cavity 100. FIG. 3A shows a state in which the metal layer 112 is formed on the surface 111 of the cavity 100 using a method such as vapor deposition. The metal layer 112 may be formed in a thin film form. When the metal layer 112 is used as an anode and an anodic oxidation reaction proceeds, an oxide layer 113 is formed as shown in FIG. When the reaction is continued, as shown in FIG. 3C, a large number of pores are formed in the oxide layer 113, and the porous oxide layer 113 is formed.

  In the foregoing, a method for forming an oxide layer by anodic oxidation has been described. Below, the method of forming a catalyst layer and the role of the catalyst layer will be described.

  After the porous oxide layer is formed through the anodic oxidation reaction, the catalyst mother layer is supported and then dried to form the catalyst layer. The material constituting the catalyst layer can be platinum Pt or rhodium Rh.

  The odor-inducing molecule generated in the cooking object reacts with the catalyst layer and changes to carbon dioxide and water. Of course, not only odor-inducing molecules but also contaminants that should not be contained in food are chemically burned and removed by catalytic reaction.

  In order for the odor-inducing molecule or pollutant to cause a catalytic reaction, the following two conditions are preferably satisfied. First, the surface area of the catalyst layer must be large and the possibility of molecular collisions should be high. Second, it must be maintained at 200-250 ° C. at temperature conditions suitable for catalytic reactions. In the case of the first condition, the surface area of the catalyst layer can be increased by forming the catalyst layer on the porous oxide layer. This is the reason for using the anodizing reaction in the present invention. In the case of the second condition, an additional heater can be further provided to provide the temperature condition, but the oven in the cooking device is not difficult to reach a temperature range of about 200 to 250 ° C. Therefore, there is an advantage that the effect of the present invention is doubled.

  Hereinafter, second to fourth embodiments of the cavity of the cooking device according to the present invention will be described with reference to FIGS.

  According to the second embodiment of the cavity of the cooking device according to the present invention shown in FIG. 4, the radiant heat transmitted from the heater included in the cooking device can be transmitted directly without being blocked. A structure further including an opening on the lower surface of 100 is shown. In this case, there is an advantage that the radiant heat transmitted from the heater is easily transmitted into the cavity 100. Of course, the position where the heater is installed can be on the upper side or the left and right sides, so that the opening is not formed only on the lower side of the cavity 100, but the opening is formed on at least one surface of the cavity 100 facing the heater. Can also be formed.

  According to the third embodiment of the cavity of the cooking device according to the present invention shown in FIG. 5, a structure is shown in which the open portions are all formed on the upper surface and the lower surface. If the cavity 100 is manufactured using a mold, it is easier in the manufacturing process to join the cavity 100 after forming the cavity 100 in a two-stage structure on the left and right sides. When the separated cavities 100 are joined, they can be fixed via the connecting member 120.

  On the other hand, the cavity 100 can be configured to be detachable from the cooking device. There are various detachable structures. As shown in FIG. 5, after forming the thread groove 130 in the cavity 100, the bolt 131 is used as shown in FIG. A structure coupled to the main body 10 can also be adopted.

  An inner surface of the cavity 100 may further include a locking bar 140 so that a tray 150 for supporting an object to be cooked can be disposed.

  According to the fourth embodiment of the cavity of the cooking device according to the present invention shown in FIG. 7, the sliding portions 160 are provided in pairs on the left and right sides of the cavity 100, and can be more easily detached from the cooking device. it can. The sliding parts 160 may be formed in pairs on the upper and lower sides of the cavity 100 instead of the left and right sides.

  As shown in FIG. 8, the sliding guide part 11 that can hold the sliding part 160 is provided inside the main body 10 of the cooking device, and the cavity 100 can be easily detached. . If the cavity 100 can be easily separated from the main body 10, the cavity 100 can be separately cleaned and managed, so that more hygienic management is possible.

Hereinafter, with reference to FIG. 9, one Example of the auxiliary tool for heat cooking apparatuses by this invention is described.
According to the above-described embodiment, the catalyst layer is formed in the cavity 100 itself to cause the catalytic reaction. However, the auxiliary appliance for the cooking device to be described later is manufactured separately from the cavity 100 and provides an auxiliary appliance having a deodorizing function. To do.

  A porous oxide layer is formed on at least a part of the surface of the auxiliary device through an anodic oxidation reaction. The catalyst layer is formed on at least a part of the surface of the oxide layer by supporting the catalyst mother liquor and then drying. When driving the cooking device, an auxiliary device may be disposed in the cavity 100 so that the odor-inducing molecules generated from the cooking object can be decomposed by causing a catalytic reaction in the catalyst layer.

  At this time, as shown in FIG. 9, the auxiliary tool may be the tray 150 itself that supports the cooking object. That is, since the tray 150 is also heated, even if a catalyst layer is formed on the tray 150, the catalytic reaction proceeds and has a deodorizing function.

  Meanwhile, the auxiliary device may be separately manufactured in the form of a structure 170 attached to the inside of the cavity 100 as illustrated in FIG. According to such a structure, since the oxide layer can be formed more easily than when the entire cavity 100 is subjected to an anodic oxidation reaction, there is an advantage in the manufacturing process.
