In addition, a hot plate 15 is formed on the upper contact surface of the radiant heating member 11, and a cooking apparatus such as a pan is placed on the upper surface of the hot plate 15 to cook food. .

In addition, the outer side of the hot plate 15 is supported by the cooktop frame 16, the position of the hot plate 15 can be supported. In addition, the hot plate 15 may be seated in the groove of the upper end of the cooktop frame 16 to support the formation position.

In addition, the support panel 25 is formed on the lower side of the radiant heating member 11 spaced apart from each other, and the lower end of the cooktop frame 16 and the forge fixing portion 30 are formed at both ends of the support panel 25. do. The first fastening member 26 illustrated as a screw is inserted into and fixed to the fixing part 30, so that the support panel 25 may be firmly fixed to the cooktop frame 16.

In addition, the heater support bracket 20, which is an elastic body, is inserted between the radiant heating member 11 and the support panel 25, so that a restoring force for pushing the radiant heating member 11 upward is continuously applied. In addition, at least one side of the radiant heating member 11 and the heater support bracket 20 is fixed to the second fastening member 19, so that the radiant heating member 11 may be firmly supported.

In detail, the upper end of the heater support bracket 20 is formed to surround the heater edge 50 which is a bent portion of the edge of the radiant heating member 11, so that the radiant heating member 11 is a heater support bracket 20 To be firmly supported.

Hereinafter, the heater support bracket 20 and the support panel 25 will be described in more detail. 4 is a perspective view of the heater support bracket, Figure 5 is a perspective view of the support panel.

Referring to FIG. 4, the heater support bracket 20 is aligned with the radiant heating member 11 in a state in which a guide part 33 formed to surround the heater edge 50 and a predetermined fixing hole are formed. In the state that the second fastening member 19 is fastened to the fastening portion 34, extending from the fixing portion 34 and the bottom surface of the radiant heating member 11 in contact with the radiant heating member 11 is supported A first bent portion 35, a second bent portion 36 extending in the opposite direction of the first bent portion 35 in a state where the first bent portion 35 and a predetermined bending portion are intervened; The third bent part 37 extending in the direction opposite to the extending direction of the second bent part 36 and the elastic fixing protrusion 31 to which the heater support bracket 20 is fixed to the support panel 25 are included. do.

In detail, the guide part 33 is formed in the same shape as the heater edge 50 so that the radiant heating member 11 is firmly fixed by the heater support bracket 20. In addition, the fixing part 34 is also formed in the same shape as the lower side of the radiant heating member 11 so that the radiant heating member 11 is firmly supported with respect to the heater support bracket 20. In addition, the first bent part 35 is formed in a horizontal plane having the same shape as the bottom surface of the radiant heating member 11 so that the bottom surface of the radiant heating member 11 is entirely supported.

In addition, the second bending portion 36 and the third bending portion 37 are formed by being bent in opposite directions to each other, so that the bending operation between the two can be smoothly generated. In other words, when the impact is applied from the outside, the second bending portion 36 and the third bending portion 37 are smoothly bent to each other, so that the impact from the outside can be buffered. Of course, the first bent part 35 may also be bent in response to external shock, thereby acting as a shock absorber. The first, second, and third bends 35, 36, 37 may be understood as overall buffers. Such a shock absorbing portion includes a plurality of flat plane portions extending in opposite directions to each other, and the bending function of the shock absorbing portion is performed to perform a shock absorbing role of the external impact.

Of course, if the buffer portion is not necessarily opposite to each other, as long as a plurality of bending portions that are gently deflected are formed, the function as the buffer portion may be performed. However, in order to more fully perform the function of the shock absorbing, it is preferable that a plurality of planar portions extending in opposite directions to each other are formed.

In addition, the elastic fixing protrusion 31 has a lower end portion is made of a point, and a portion extending in a predetermined distance from the top of the point is formed by the engaging portion 32 is a width between the gap is formed, the elastic fixing protrusion 31 After is inserted into the insertion portion 29, the elastic fixing projection 31 is fixed to the support panel 25 by the operation of the locking portion 32 is expanded. In addition, the mounting portion 32 seated on the upper side of the support panel 25 is formed to extend to a predetermined length at one side extending from the elastic fixing protrusion 31, whereby the position of the elastic fixing protrusion 31 is secured. Be guided.

In addition, by forming a ridge 39 for maintaining a predetermined distance with respect to the support panel 25 at the upper side of the elastic fixing projection, the user is easily elastically fixed by holding the elastic fixing protrusion 31 easily The projection 31 can be operated. For example, when the user grasps the elastic fixing protrusion 31 and presses the inside of the insert 29, the locking portion 32 can pass through the insert 29 more easily. It is possible to obtain an effect of improving the convenience of the operator.

Referring to FIG. 5, the support panel 25 is a plate-shaped frame, in which a portion of the heater support bracket 20 is inserted and supported, and at both ends of the support surface 27. Reinforcing ribs 28 to be bent in one direction to reinforce the strength of the support surface 27, and the fixing portion 30 is formed to be bent at a predetermined inclination angle at the end of the support surface 27.

In detail, a rectangular insertion portion 29 into which the insertion end 36 is inserted is formed at a predetermined position of the support surface 27. As described above, the elastic fixing protrusion 31 is inserted into and fixed to the support panel 25 in the inserting portion 29. The elastic fixing protrusion is inserted into the support panel 25. The heater support bracket 20 may be fixed.

In addition, the reinforcing ribs 28 are bent on both sides of the support surface 27, so that the moment of inertia of the support surface 27 is increased, thereby preventing bending of the support surface 27.

The operation or action of the installation structure of the heating member according to the present invention will be described in detail. First, both ends of the support panel 25 are firmly fixed to the cooktop frame 16 by the first fastening member 26. At the same time, the heater support bracket 20 is firmly fixed to the lower side of the radiant heating member 11 by the second fastening member 19. Of course, when the heater support bracket 20 is fixed to the radiant heating member 11, the guide part 33, the fixing part 34, and the first bent part 35 are the radiant heating member 11. By contacting a predetermined position of), eventually, the radiant heating member 11 can be firmly supported by the heater support bracket 20.

Thereafter, the heater support bracket 20 is fixed to the support panel 25 by a predetermined type of locking operation in a state of being fixed to the radiant heating member 11. In other words, the elastic fixing protrusion 31 is fitted to the insertion portion 29 to be fixed. In addition, when the elastic fixing protrusion is inserted into the insertion portion 29, the support panel 25 is already fixed to the cooktop frame 16. After that, when the hot plate 15 is placed on the upper side of the radiant heating member 11, the entire cooktop configuration is finished.

As such, in the state where the heater support bracket 20 is fixed to the lower side of the radiant heating member 11 by the second fastening member, the elastic fixing protrusions 31 of the lower side of the heater support bracket 20 are supported by the support panel. Since the installation work of the radiant heating member 11 is completed by the action of being inserted into and fixed to (25), the effect of improving the working convenience can be obtained.

In addition, as described, after the installation of the radiant heating member 11 is finished, the heater support bracket 20, in particular, the first, second and third bends 35, even when an unexpected external shock is applied. Since the shock absorbing portion including the 36 and 37 elastically deforms to absorb the shock, the tightness of the radiant heating member 11 and the hot plate 15 can be maintained more accurately. In addition, it is possible to prevent damage to the device caused by the impact between the parts. In particular, since the contact surface of the radiant heating member 11 and the hot plate 15 can be maintained in the installation state at the time of manufacture by the buffer part, the radiation heating member 11 generated from the contact surface is damaged or hot. Scratch of the plate 15 can be prevented.

On the other hand, even if the radiation heating member 11 as proposed is installed, there is a case that a stronger impact from the outside is applied to the oven during operations such as packaging and moving. At this time, since a relatively large impact is applied to the heater support bracket 20, the bracket may be deformed beyond the limit of elasticity, thereby causing permanent failure. The support panel 25 is suspended from the cooktop frame 16 in order to maintain the high density of the contact surface of the radiant heating member and the hot plate even when a stronger impact is applied than such a state of being used. You can also do that. In other words, when the support panel 25 is fixed to the cooktop frame 16, the predetermined elastic means exemplified by the spring is mediated, so that the support panel 25 is elastically deformed against external impact. have. At this time, the external impact will be applied to the radiant heating member 11 after being buffered at the same time by the elastic means and the heater support bracket 20 between the support panel and the cooktop frame 16 at the same time. Therefore, the long density of the radiant heating member 11 and the hot plate 15 may be maintained more reliably.

By the installation structure of the heating member according to the present invention, the heating member can be reliably operated without failure. In other words, there is an advantage that the fear of damage is reduced even when an external impact is applied. In addition, even if the product is used for a long time, since the tightness between the heating member and the hot plate can be maintained, the service life of the product can be further increased.

In addition, since the installation process of the heating member can be performed simply, it is possible to obtain an effect of increasing the convenience of the manufacturing operation.

In addition, since breakage of the radiant heating member or breakage of the hot plate caused by external impact can be prevented, there is an advantage in that the reliability of the product is further increased.
