Inner ring fire cover, combustor and gas stove

Abstract

The invention discloses an inner ring fire cover, a combustor and a gas stove. The inner ring fire cover comprises a top cover, an outer ring wall, an inner ring wall and a connecting plate, wherein the top cover is disposed on the outer ring wall; the inner ring wall is disposed inside the outer ring wall, and a central cavity is formed in the middle of the inner ring wall; and the connecting plate is disposed between the outer ring wall and the inner ring wall, the top cover, the outer ring wall and the connecting plate enclose a first inner ring gas cavity in communication with the centralcavity, first inner ring fire holes communicating with the first inner ring gas cavity are formed in the top cover at intervals in the circumferential direction, second inner ring fire holes communicating with the first inner ring gas cavity are formed in the outer ring wall, a second inner ring gas cavity is formed by enclosing the outer ring wall, the connecting plate and the inner ring wall, and flame stabilizing holes communicating with the second inner ring gas cavity are formed in the outer ring wall at intervals in the circumferential direction. According to the inner ring fire cover,,the gas load of the first inner ring fire holes can be reduced, so that the inner ring fire cover can maintain the stable combustion state in an extremely small fire state.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an inner ring fire cover, a burner and a gas cooker. Background technique [0002] The inner ring fire cover is used to be installed on the burner to form an inner ring fire for heating the bottom of the pot near the center. The existing inner ring fire cover is provided with an inner ring gas cavity, and gas is input into the inner ring gas cavity through the inner ring gas input channel. flame stabilizing hole. Since the main fire hole, side fire hole and flame stabilizing hole on the existing inner ring fire cover are all connected to the inner ring gas chamber, the gas load of the inner ring gas chamber cannot be made very small. The gas load of the fire hole is also relatively large. Contents of the invention [0003] The main purpose of the present invention is to provide an inner ring fire cover, a burner and a gas cooker, aiming at improving the problem of large g...
