[Problems to be solved by the invention]
In the former example of the conventional example, since the four members of the front frame member, the rear frame member, and the side frame members on both sides are connected via the connection fittings, there is a problem that the assembly becomes complicated and the connection is made. There is a problem that a special member is required, and there is a problem that the appearance is deteriorated because there is no sense of unity in the joint of the corner portion. In the latter case of the conventional example, there is a problem in that a special mold is required for stamping and molding a plate with a press, so that the investment cost for the mold is increased and the cost is increased.
[0006]
The present invention has been made in view of the above points, can be easily assembled by bending a long frame material, can be formed at a low cost and can be formed with a good appearance without a joint in the corner, It is another object of the present invention to provide a top plate frame of a cooking appliance that can be assembled without using a special member for connection.
[0007]
[Means for Solving the Problems]
The top plate frame A of the cooking appliance of the present invention for solving the above-mentioned problems is provided with a protruding strip 8 protruding in the longitudinal direction on one side edge parallel to the longitudinal direction of the long strip-shaped frame material 1 in the longitudinal direction. The bending groove 2 is provided at a predetermined interval in the longitudinal direction of the frame material 1 and is formed at a predetermined interval from the other side edge of the frame material 1 where there is no protrusion 8 to the front of the protrusion 8. The frame material 1 is bent with the side having the bending groove 2 at the inner corner side, and is formed into a rectangular frame shape composed of the front frame portion 3, the side frame portions 5 on both sides, and the rear frame portion 4. Both ends in the longitudinal direction are butted at the portion of the rear frame portion 4, and an exhaust cover receiver 7 for attaching the exhaust cover 6 is disposed along the rear frame portion 4 and the portion of the frame material 1 in front of both ends in the longitudinal direction and characterized in that the concatenation of longitudinal ends of to the frame material 1 secured to respective exhaust cover receiving 7 That.
[0008]
By constructing as described above, the bending groove 2 is formed in the frame material 1 that can be formed by extrusion molding or the like, and the top plate frame A can be assembled by bending at the bending groove 2 to be bent into a frame shape. it can. As a result, the corner portion only needs to be bent at the bending groove 2, and assembling becomes easy, and the corner portion can be integrally connected and formed with good appearance. In addition, the cost can be reduced without the need for investment in a special mold as in the case of press molding integrally. Further, since there is a ridge 8 on the upper surface of the outer periphery of the top plate frame A, when the top plate 9 is fitted, the end surface around the top plate 9 can be supported by the ridge 8 and the end surface around the top plate 9 can be seen. The appearance can be finished so that there is no. Further, the corner portion can be smoothly bent by the bending groove 2 provided by leaving the ridges 8 along the end face around the top plate 9.
[0010]
Further, a bent groove 2 is formed in the frame material 1 that can be formed by extrusion molding or the like, and the bent frame 2 is bent at a portion of the bent groove 2 to form a rectangular frame shape composed of the front frame portion 3, the side frame portion 5, and the rear frame portion 4. The top plate frame A can be assembled by bending the frame material 1 in the longitudinal direction and butting the end portions of the frame material 1 to the exhaust cover receiver 7 together. As a result, the corner portions at the four corners need only be bent at the bending grooves 2, and the assembly can be facilitated and the corner portions can be integrally connected and formed with good appearance. Further, the end portions in the longitudinal direction of the frame material 1 are connected by the exhaust cover receiver 7 for receiving the exhaust cover 6, so that it is not necessary to use a special connection fitting, and the number of parts can be reduced. And cost reduction.
[0011]
Further, it is also preferable that the frame material 1 is fixed to the exhaust cover receiver 7 by driving a fixing tool 16 such as a screw into the exhaust cover receiver 7 from the front part of both ends in the longitudinal direction of the frame material 1. . In this case, the frame material 1 can be fixed to the exhaust cover receiver 7 simply by driving the fixing tool 16 such as a screw into the exhaust cover receiver 7 from the frame material 1, and the longitudinal ends of the frame material 1 are connected to each other. Easy assembly.
[0012]
In addition, it is also preferable that the protruding portion 8 located at the outer corner portion at the corner portion is bent in an arc shape when viewed from the plane. In this case, since the ridges 8 located at the outer corners at the corners are bent into an arc shape from the plane, the ridges 8 can be smoothly bent and the corners can be rounded to improve the appearance.
[0013]
