The present invention relates to a heat sink packing assembly structure of the electric rice cooker, in particular, the packing is inserted and fixed by the inner heat sink and the top and the fixed body formed in the lid body, it is seated on the upper portion of the inner pot to prevent the leakage of steam and sealed By making it, it relates to a heat sink packing assembly structure of the electric insulation rice cooker to improve the cooking performance and insulation.

Generally, as shown in FIG. 1, the electric rice cooker 100 includes a main body 3 having an inner pot 9 for storing rice therein, and an upper part of the main body 3 formed to open and close the inside. It consists of the lid body 1.

In the above, the assembling structure of the heat dissipation plates 23 and 29 and the packing 35 of the lid 1 will be described according to the conventional main sectional view (a) and (b) shown in FIG. The protrusion 17 of the packing 15 is inserted into the lower portion formed in the bent portion 13 of the upper frame 11 coupled to the hook 11, and the locking jaw 21 of the second heat dissipation plate 23 is inserted into the protrusion 17. The insertion and fixation of the second heat dissipation plate 23 and the packing 15 to the upper frame 11 by a plurality of screws (25).

In addition, a hole 39 is formed in the center of the second heat dissipation plate 23, and a fixed shaft 33 is inserted into and fixed to the bottom by a nut 37, and the through hole 31 is formed in the fixed shaft 33. Is formed.

The first heat dissipation plate 29 is inserted into and fixed to the coupling portion 36 formed at one side of the packing 35, and the outside thereof is in close contact with one side of the inner pot 27.

The fixed shaft 33 penetrates and is inserted and fixed by the nut 37, and the fixed shaft 33 fixes and supports the packing 35, and the packing 35 is attached to the first heat sink 31. It is inserted and has a structure for supporting and fixing the first heat dissipation plate 31.

In the heat sink packing structure of the conventional electric thermal rice cooker configured as described above, a process of assembling the heat sinks 23, 29 and the packings 15, 35 on the top 11 as shown in (a) of FIG. Since the plurality of screws 25 are inserted into and fixed around the second heat dissipation plate 23, when the first heat dissipation plate 29 is not present, the screws 25 are exposed as they are when the lid 1 is opened, and the appearance is not beautiful. In addition, the prevention jaw 19 formed in the packing 15 prevents the discharge of steam to the outside.

In addition, the first heat dissipation plate 29 is fixed to the fixed shaft 33 and the packing 35 in order to prevent condensation on various fastening sites due to condensation on the second heat dissipation plate 23 due to steam inside during cooking or warming. It is fixed by, but because the packing 35 is holding only the central portion, the abnormal sound occurs when opening and closing the lid (1).

And because the endothelial cover is formed by bending the edge of the edge in multiple stages to be seated inside the inner pot (27), difficulties occur in the manufacturing process and the defective rate increases, causing the cost increase, the bone formed in the packing 15 Digging prevention jaw (19) has a problem that the surface close to the upper portion of the inner pot (27) to reduce the warmth or airtightness of the electric insulation rice cooker and foreign matter accumulated during long-term use.

The present invention has been devised to solve the conventional problems as described above, the packing is inserted and fixed by the inner heat-dissipating plate and the top and the fixed body formed in the lid body, it is seated on the upper portion of the inner pot to prevent the leakage of steam, In addition, the heat sink and the packing are configured without bending to prevent foreign matters from accumulating, and the simple structure makes the heat sink packing assembly structure of the electric heat cooker which improves productivity and heat insulation while improving productivity and heat retention. The purpose is to provide.

The heat sink packing assembly structure of the electric thermal rice cooker made to achieve the object of the present invention as described above is formed of a main body having an inner pot for holding the rice, and the electric body including a lid formed to open and close the inside of the main body In the insulated rice cooker, the projection of the multi-stage bent is coupled to the lower portion of the lid body, the lower portion of the upper to form a multi-stage curved fixture having a locking fastener, and the locking of the fixed body The fixing jaw is inserted into the fixing jaw of the multi-stage bent with a fixed protrusion is fixed tightly to the locking jaw of the fixing jaw and the fixing body of the top, the support is formed on one side of the packing is inserted into the fixing groove of the fixing body, The lower portion of the support of the U-shaped inner heat sink is in close contact with the top and the fixed body by a screw, the bottom of the packing is fixed close to the top of the inner pot To provide a heat sink structure of the electrical insulating packing cooker as claimed. Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to FIGS. 3 to 4 of the accompanying drawings.

First, in the electric heating rice cooker 100 including a main body having an inner pot for holding rice therein and a lid body 50 formed on the upper part of the main body to open and close the inside, the lid body 50 is It is formed of an upper frame 53, a fixed body 60, a packing 70, and an inner heat dissipation plate 90.
