It relates to a gas stove with five virtues.

  Conventionally, this kind of gas stove has a burner ring that is placed on the top plate in an extrapolated state on the stove burner, and the virtues are positioned by externally fitting a five-virtual annular virtuosity frame to this burner ring. It has been known. A gas stove is also known in which an annular ridge corresponding to the above-described burner ring, which is positioned on the top plate at the peripheral edge of the burner opening and fitted with a five-virtual annular virtuosity frame, is drawn (for example, a patent). Reference 1). According to this, burnering becomes unnecessary, and the number of parts can be reduced to reduce the cost.

  However, it has been found that the following problems occur when an annular ridge is drawn on the top plate. In other words, the annular ridge is easily heated by the radiant heat from the flame of the burner, the top plate is thermally expanded by heat input from the annular ridge, and the top plate is deformed so that the annular ridge is displaced upward. It becomes easy. And once the annular ridge is displaced upward, the amount of heat input to the annular ridge increases to approach the flame, and the upward displacement of the annular ridge due to the thermal expansion of the top plate becomes considerably large. End up. For this reason, when the top plate cools and contracts due to the stop of combustion of the stove burner and tries to return to the initial state, a large reversing sound is generated and the user is surprised.
