    摘要： An injet for a gas burner includes a first gas orifice and a second gas orifice. An injet body defines an air passage and a gas passage. The first and second gas orifices are mounted to the injet body. A pneumatically actuated gas valve blocks a flow of gaseous fuel through the gas passage to the second gas orifice in a closed configuration. The pneumatically actuated gas valve is configured to adjust from the closed configuration to an open configuration in response to a flow of air through the air passage. A flow restriction body is disposed upstream of the pneumatically actuated gas valve. The flow restriction body defines a through hole via which air is flowable to pneumatically actuated gas valve.

    摘要： A gas burner assembly for a cooktop appliance and a method for operating the same are provided. The gas burner assembly includes a normally aspirated primary burner, a concentrically-positioned forced air boost burner, a boost valve for regulating a flow of boost fuel to the boost burner, and a forced air supply source for providing a flow of air to the boost burner. The method includes activating the boost burner upon receiving a command and starting a timer. After a predetermined amount of time has passed, e.g., such as ten minutes, the boost burner is extinguished by closing the boost valve to prevent unsafe operating conditions.

    摘要： A blower assembly for a gas-burning appliance includes a blower and a motor coupled to the blower and configured to turn the blower to provide airflow through the gas-burning appliance. The blower assembly also includes a housing enclosing the blower and the motor. The housing a first portion and a second portion coupled to the first portion. The first portion and the second portion define a cavity therebetween to receive the motor and the blower. The blower assembly further includes an inlet sleeve coupled between the first portion and the second portion. The inlet sleeve is configured to couple to the gas-burning appliance and receive the airflow from the gas-burning appliance. The blower assembly also includes a seal extending at least partially around the inlet sleeve and at least partially between the inlet sleeve and at least one of the first portion and the second portion.

    摘要： A gas burner includes a burner body that defines a plurality of forced induction flame ports. An air outlet orifice is mounted to an injet body at an outlet of an air passage such that the air outlet orifice is oriented for directing a flow of air towards the plurality of forced induction flame ports. A gas outlet orifice is mounted to the injet body at an outlet of a gas passage such that the gas outlet orifice is oriented for directing a flow of gaseous fuel towards the plurality of forced induction flame ports. A pneumatically actuated gas valve is positioned within the injet body. The pneumatically actuated gas valve is configured to adjust from a closed configuration to an open configuration in response to the flow of air through the air passage.

    摘要： There is provided a combustion plate in which the combustion resonant sounds and instability at the time of high-load combustion can be resolved and in which a large opening ratio of the flame holes can be secured. Flame holes of an equal diameter are formed evenly over an entire surface of a combustion region of a plate main body in such a positional relationship that adjoining three flame holes form an equilateral triangle. Provided that a flame hole group which is made up of six flame holes disposed in a positional relationship to form an equilateral hexagon and one flame hole in the center of the equilateral hexagon is defined as a unit flame hole group when disposed adjacent to another flame hole group across a large equilateral hexagon enclosing the equilateral hexagon, there is formed in the surface of the plate main body a bottomed hole.
