If the first fixing screw 18 is fastened to the first screw portion 14 in a state where the first fixing fitting 15 is overlapped with the main body side surface 12, the protrusion from the main body side surface 12 becomes about 5 to 6 mm. When 11 is dropped into the hole 20, it can be installed without disturbing.

5 to 10, reference numeral 19 is a countertop having a hole 20. 31 is the main body 3
2 is a flange provided on the upper end of the counter 2, and is locked on the countertop 19. 33 is a comb-shaped slot hole of a plurality of slit holes provided on the side surface 34 of the main body, and 35 is a comb-shaped slot hole 33.
Is a second screw portion provided in the vicinity of. Reference numeral 36 denotes a fixed plate, which is substantially rectangular and has a through hole 37 at one end thereof. 38 is a coil spring, and the fixing screw 39 is the fixing plate 3.
It is fastened to the second screw portion 35 via 6 and the coil spring 38. The other end of the fixing plate 36 is inserted into the comb-shaped slot 33 and abuts against the lower end of the countertop 19 to be fixed. Reference numeral 40 denotes a sheet metal comb plate having a comb slot 33 and a second screw portion 35, which is fixed to the side surface 34 of the main body by spot welding.

In FIGS. 11 to 16, 19 is a countertop, 51 is an upper unit portion which is a main body of an electric cooker made of sheet metal and having a built-in heating source, and 52 is a side surface of the upper unit portion 51. The fourth screw portion 53 provided is a lower unit portion suspended from the upper unit portion 51 by a rail or the like. 54 is a fixed base fixed above the front surface of the lower unit portion 53, and 55 is a metal plate having a substantially U-shaped cross section and a through hole 56 and a third
Is a fastening plate having a screw portion 57, 58 is a third fixing screw to be inserted into the through hole 56, and 59 is a holding plate made of sheet metal and having a second long hole 60. The fastening plate 55 is placed on the upper portion of the fixed base 54 so as to cover the opening side having a substantially U-shaped cross section, and the pressing plate 59 is positioned in front of the fastening plate 55. Reference numeral 61 denotes a screw E that engages with the third screw portion 57, and includes a push plate 59, a fastening plate 55, and a fixed base 5.

Reference numeral 3 denotes a backing plate having a shape in which a part of the metal plate of the fixed base 54 is cut and raised, and serves as a contact when the screw E61 of the fastening plate 55 is clamped.

The operation of the electric cooker configured as described above will be described. In the case of the first aspect of the invention, the first fixing screw 18 penetrates the slotted hole 16 of the elongated hole and is engaged with the first screw portion 14, so that the first fixing metal fitting 15 is the plate thickness of the countertop 19. It is possible to change the position and angle of the contact surface according to the requirements. Further, since the first fixing member 15 can be fixed so as to be overlapped with the main body side surface 12 before mounting, the first fixing member 15 has a small amount of protrusion and can be easily set in the hole 20.

In the case of the second invention, since the mounting direction of the first fixing member 15 can be both vertical and horizontal, it can be mounted even if the plate thickness of the countertop 19 is largely changed.

In the case of the third aspect of the invention, the fixing screw 18 can be fastened from the lower front side, which matches the inclination of the first fixing member 15.

In the case of the fourth invention, the fixed plate 36 is biased upward by the coil spring 38, and when the fixing screw 39 is tightened with a screwdriver, the tip of the fixed plate 36 is rotated at first and the counter plate is rotated. The fixing plate 36 is not inserted into the comb-shaped slot 33 because it hits the end surface of the top 19. But,
When the fixing screw 39 is continuously tightened, the tip of the fixing plate 36 no longer contacts the end surface of the countertop 19, and at the same time, the fixing plate 36 is inserted into the comb-shaped slot 33. Further, if the fixing screw 39 is continued to be tightened as it is, the fixing plate 36 is fixed to the counter top 19 with the end surface of the comb-shaped slot 33 as a fulcrum.

In the case of the fifth invention, the operation is the same as that of the fourth invention, but since the comb-shaped plate 40 is a separate component, it can be retrofitted by spot welding after being processed as a small component. Become.

In the case of the sixth invention, the upper unit portion 51 is
After being fixed to the countertop 19, the third fixing screw 58 is engaged with the fourth screw portion 52 and continuously tightened, and when the lower unit portion 53 reaches a predetermined position, the pressing plate 59 is slid, After covering the screw head of the third fixing screw 58, the screw E51 is tightened. In this state, the lower unit portion 53 is fixed to the upper unit portion 51.

In the case of the seventh invention, the fixed base 54 has the first
Since the long hole 62 is provided, the screw E61 can be moved left and right, and accordingly, the third fixing screw 58 attached to the fastening plate 55 can also be adjusted in the left-right direction.
As a result, even if the upper unit portion 51 and the lower unit portion 53 are displaced from each other in the left-right direction, they can be fixed.

[0038]
