Abstract
An electric range is provided in which a lower surface of a base plate, on an upper end of which a working coil is placed, may be supported by at least one elastic supporter disposed at an upper end of at least one air guide along a widthwise direction of the base plate, thereby preventing bending of the base plate and maintaining a constant gap between an object to be heated and the working coil.
Claims17
An electric range, comprising:
- a case, an upper portion of which is open and having an inner space in which at least one drive circuit and at least one air blowing fan are disposed;
- at least one base plate disposed at the upper portion of the case;
- at least one working coil disposed on the at least one base plate;
- and
- at least one air guide disposed below the at least one base plate within the case, configured to cover the at least one drive circuit, and having an inlet disposed at a front end of the at least one air blowing fan;
- and
- a plurality of elastic supporters fixed at a plurality of positions to an upper surface of the at least one air guide, and configured to support a lower surface of the at least one base plate, wherein a fixing portion that fixes the plurality of elastic supporters is respectively disposed at the plurality of positions at the upper surface of the at least one air guide, wherein each fixing portion comprises a pair of support projections that is spaced a predetermined distance apart at the upper surface of the at least one air guide and protrudes upward, and a fixing projection having a first fixing hole that protrudes from the upper surface of the at least one air guide such that the fixing projection is disposed between the pair of the support projections, wherein a lower end of the elastic supporter is mounted onto upper ends of the pair of support projections and the fixing projection, and wherein a second fixing hole formed at the lower end of the elastic supporter is mounted such that a position of the second fixing hole is aligned with a position of the first fixing hole.
