Figure 2 is an exploded perspective view showing an electric stove with improved thermal conductivity according to the present invention, 1 is the body, 2 is a reflector, 3 is a support, 4 is a heating element, 5 is a fan, 6 is a guide member.

The present invention is to solve the problem on the basis of the prior art of Figure 1, the basic configuration is a main body (1) serving as a pedestal, the upper body 21 and the lower body (mounted to the upper portion of the main body 1) 22 is a janggu-shaped reflecting plate 2 of a pair, a plurality of heating element support (3) fixed to the central portion of the upper body 21 and the lower body 22 of the reflecting plate 2, and the heating element It comprises a ring-shaped heat generating element 4 which is fitted to the support (3).

The problem of the basic configuration is that the radiant heat of the self-heating of the heating element 4 can be felt only when it is close to the heating element 4 so that the blower fan 5 is mounted on the lower part of the reflecting plate 2 to solve this problem.

In addition, a plurality of wind discharge holes 22 ′ are formed in the upper circumferential surface of the lower body 22 of the reflector 2 so that the wind generated from the blower fan 5 can be moved to the heating element 4. .

On the other hand, since the wind discharged into the hole 22 'comes out of the hole 22', part of the wind diffuses into the room and only a part of the wind is transferred to the heating element 4, so efficient heat conduction is not achieved. A guide member 6 for guiding the wind discharged from ') to the heating element 4 is required.

The guide member 6 is installed at the center of the reflector 2 and expands to approach the ring-shaped heating element 4, but the wind blown from the blower fan 5 is a hole 22 of the lower body 22. ') After being discharged to form a slanted surface 61 forming a single layer in the middle portion of the ring-shaped heating element (3) to be guided to the lower side of the ring-shaped heating element (3).

Wind that is in contact with the inclined surface 61 of the guide member 6 is in contact with the lower side of the heating element 4 as shown in FIG. And some do not rise and move horizontally together to heat up the lower part of the room and the convection is moved to the upper part of the room.

Therefore, the guy member 6 is the heat conduction efficiency through the role that the air blown from the blowing fan 5 is discharged to the hole 22 'of the lower body 22 and then contact the lower end of the heating element (4) Will improve.

The rear end 31 of the heating element supporter 3 is fixed to the end of the guide member 6 by a rivet or a screw.

Next, as another embodiment of the present invention, as shown in FIGS. 5 and 6 by adjusting the position of the ring-shaped heating element 4 up and down, the wind discharged to the hole 22 'of the lower body 22 is a heating element Its improvement is to be improved so that it can be delivered to the upper, middle, and lower positions of (4).

To this end, the heating element support 3 for coupling the heating element 4 is coupled to the hinge 62 so as to be rotated after being fitted to the cut portion of the guide member 6, and raises the rear end of the heating element support 3 Alternatively, the driving means 7 for lowering and adjusting the height of the heating element 4 is mounted on the guide member 6.

The driving means 7 has a single layer (7a, 7b, 7c) is formed continuously at the bottom and the rack (7d) is formed on the upper side in order to contact the rear end of the heating element support (3) to raise or lower the upper inside The guide member 6 has an operating ring 71 having a locking groove 7e formed therein, and a locking jaw 72 'that is supported by the locking groove 7e of the operating ring 71 to rotate. A pinion connected to a support plate 72 that is riveted or screwed to the support plate 72, and a shaft 74 having a handle 73 fixed to one end in order to engage the rack 7d of the operation ring 71 to rotate the operation ring 71. It consists of a first holder 76 and a second holder 77 mounted on the support plate 72 and the safety net 8 to support the 75 and the shaft 74.

On the other hand, the pinion 75, the handle 73 and the shaft 74 is preferably arranged on the side of the power supply connection that does not generate heat of the heating element (4).

The operation of the electric stove with improved thermal conductivity according to the present invention configured as described above will be described.

First, as shown in FIGS. 3 and 4, the guide member 6 is mounted at the center of the reflector 2, and the configuration in which the heating element support 3 in which the heating element 4 is coupled to the guide member 6 is fixed. Wind blown from (5) is discharged into the hole 22 'of the lower body 22, and then the wind contacting the inclined surface 61 of the guide member 6 is in contact with the lower side of the heating element 4, the thermal conductivity While the heat generated in the upper part of the heating element 4 rises due to the flow rate moving in the horizontal direction, the convection moving to the upper part of the room after heating the lower part of the room by moving horizontally together without raising the heat emitted from the lower part Is done.

Therefore, the above-described configuration in which the heating element 4 is coupled to the heating element support 3 fixed to the guide member 6 moves only a portion of the heat emitted from the heating element 4 in the horizontal direction, thereby lowering the heat rise of the heating element 4. It can effectively prevent some of the heat delivered to the horizontal direction to feel the heat to those around you.

Next, as shown in FIG. 5 and FIG. 6 looks at the structure that can transmit the heat in the horizontal direction by adjusting the position of the heating element 4 up and down through the drive means (7).

When the handle 73 of the drive means 7 is rotated, the pinion 75 connected to the shaft 74 is rotated, and the pinion 75 is integrated with the rack 7d by moving the engaged rack 7d. The operation ring 71 formed by the rotation is simultaneously. At this time, since the locking groove 7e of the operation ring 71 is inclined to the locking jaw 72 'of the support plate 72, the locking groove 7e is safely rotated without being separated.

The initial state before the operation ring 71 is rotated is discharged into the hole 22 'of the lower body 22, as shown in Figure 6 (A) after the wind contacting the inclined surface 61 of the guide member 6 It is a state in which it is in the same position state as the heat conduction structure of the above-mentioned embodiment as a state which moves to the horizontal direction after contacting under the heat generating body 4, and made heat conduction. This state is a state where the rear end of the heating element support 3 is in contact with the single layer 7a of the operation ring 71.

Subsequently, when the operating ring 71 is rotated by the operation of the handle 73 and the pinion 75, the position of the single layer 7b is changed from the position of the single layer 7a, and at the same time, the rear end of the heating element support 3 is hinged ( 62) is axially raised and the heating element 40 coupled to the heating element support (3) is lowered by one step as shown in Figure 6 (B). In this state, after being discharged into the hole 22 ′ of the lower body 22, the wind contacting the inclined surface 61 of the guide member 6 is transferred to the center portion of the heating element 4, so that the wind is heated up and down the heating element 4. As the state of contact with the portion, since all the heat generated from the heat generating element 4 is transmitted in the horizontal direction, the temperature to feel the body is high.

Subsequently, when the handle 73 and the pinion 75 are operated again to rotate the operation ring 71, the position of the single layer 7c is changed from the position of the single layer 7b, and at the same time, the rear end of the heating element support 3 is hinged. The heat generating element 40 coupled to the heat generating element support 3 is further raised to the axis 62 and is lowered in two steps as shown in FIG. In this state, after being discharged to the hole 22 'of the lower body 22, the wind contacting the inclined surface 61 of the guide member 6 is transferred to the upper portion of the heating element 4, so that the wind is upper side of the heating element 4. As the state in contact with the portion, the upper heat of the heat generated from the heat generating element 4 is transmitted in the horizontal direction, so that the higher temperature than that in the state of FIG. It is possible to heat up the room efficiently because it rises after transferring heat in all directions in the horizontal direction.
