• the present invention relates to the field of gas cookers, in particular embedded gas cookers, and to a guide disk, which may also be referred to as a liquid containing disk, for a gas cooker.
• Gas cookers are household cookers commonly used in people's daily life, and mainly use liquefied flammable gas as fuel for combustion.
• the liquefied flammable gas may be natural gas, liquefied gas, and biogas.
• the gas cookers are classified into liquefied gas cookers, coal gas cookers, and natural gas cookers.
• the gas cookers may also be classified into single gas cookers, double gas cookers, single-burner gas cookers, multiple-burner gas cookers, table gas cookers, and embedded gas cookers.
• the embedded gas cooker gradually becomes a trend.
• a prominent problem is that, a cabinet with the gas cooker embedded is tightly sealed, so air supply required by an ejector is insufficient.
• the technical solution of top air inlet is proposed, that is, an upper portion of the gas cooker is opened with an air inlet for conveying air necessary for diluting gas to the ejector.
• a typical technical solution is to open an air inlet on a liquid containing disk, as described in
