The present disclosure belongs to the technical field of the combustion heating stove, and disclosed is a stove including a stove body, an air inlet channel and an exhaust channel. When the stove body is used in an enclosed space, an air inlet end of the air inlet channel is in communication with an outside of the enclosed space, a connection end of the air inlet channel is in communication with an air inlet of the stove body, the air inlet channel is operative to introduce air into the stove body from the outside of the enclosed space; and a connection end of an exhaust channel is in communication with an exhaust port of the stove body, an exhaust end of the exhaust channel is in communication with the outside of the enclosed space, whereby the exhaust channel is operative to discharge exhaust gas in the stove body out of the enclosed space.

A cooking device may include a housing, a gas burner, an unburned gas vent assembly, and a vent. The unburned gas vent assembly may include a gutter disposed in the housing and at least a portion of the gutter may be disposed below at least a portion of the gas burner. The vent may be in fluid communication with an inner volume of the gutter to enable a gas disposed in the gutter to exit the housing via the vent. The gas burner may extend from the first portion of the housing to the second portion of the housing, the vent may be disposed in the second portion of the housing, and the gutter may be sloped from the first portion of the housing to the second portion of the housing.

A device for treating vapors includes a fluid-tight container that has a vapor inlet, a vapor outlet and a through-flow connection which connects the vapor inlet to the vapor outlet in particular along a direction of flow, wherein the container can be at least partially filled with a cooling fluid.

An exhaust gas collection system for a gas burner assembly includes a plurality of concentric rings surrounding the gas burner assembly. Each concentric ring defines a support surface for supporting a cooking utensil, with the height of the support surfaces increasing further away from the gas burner assembly. The concentric rings define a plurality of plenums that are fluidly coupled with an exhaust fan for collecting and discharging exhaust gases. In this manner, the exhaust fan traps, collects, and discharges exhaust gases regardless of the size of cooking utensil being heated.

A domestic home gas cooktop is provided. The cooktop has a top sheet having a primary combustion air hole through the top sheet; a gas burner cup mounted to the top sheet; and a gas burner base mounted to the burner cup. The primary combustion air hole is configured to allow first primary combustion air to flow from beneath the top sheet to the burner base, and the primary combustion air hole is located remotely from the burner cup.

A gas collapsible stove includes an expandable combustion chamber formed from nested annular rings that can collapse to about the height of a single ring and expand into a combustion chamber for burning combustible materials. Ventilation holes at the bottom of the combustion chamber provide airflow into the combustion chamber. The combustion chamber is frustoconical and narrows at the top which increases air flow into the combustion chamber via the Venturi effect. Combustible fuels can be added and ignited in the combustion chamber and cookware containing food can be placed onto an associated top plate suspending the combustion chamber. A gas head with a plurality of gas apertures can be inserted through a bottom plate secured to the bottommost annular ring to allow a combustible gas to be used as a combustible fuel in the combustion chamber.

A motor-actuated actuated-vent-valve is configured to operatively couple to a vent port of a solid-fueled cooker. The vent port is in series with both a flow of air into a combustion region of the cooker, and a flow of resulting combustion gases from the cooker, the flow of air being responsive to a position of the actuated-vent-valve. A first controller adapted to receive a sensed-temperature signal responsive to a temperature within a cooking region of the cooker, and operatively coupled to an externally-located actuator motor of the motor-actuated actuated-vent-valve, provides for automatically electronically controlling the position of the actuated-vent-valve to a continuum of positions within a range of the positions, thereby substantially regulating the first temperature within the cooking region of the solid-fueled cooker to a user-defined temperature level responsive to the sensed-temperature signal by controlling an exclusively-naturally-occurring flow of air into the combustion region of the cooker.

Various embodiments disclosed herein provide for a variable exhaust oven that can modify an exhaust rate of an exhaust fan of the oven based on the firing rate or burn rate of a burner of the oven while still complying with safety regulations. By reducing the exhaust rate of the variable exhaust oven when the burn rate decreases, the variable exhaust oven can save costs by reducing the thermal energy lost due to unnecessary removal of air from the oven, and can lower electrical costs by operating the exhaust fan at a lower speed. The burn rate of the burner is controlled based on a temperature within the variable exhaust oven. A flame safety controller, or other controller, of the variable exhaust oven can control the exhaust rate of the exhaust fan (fan speed and/or damper adjustment) based on the burn rate of the burner.

An actuated vent valve external of, and in series with a vent port of, a solid-fueled cooker is automatically controlled by controlling a flow of air into a combustion region of the solid-fueled cooker so as to substantially regulate a first temperature within a cooking region of a solid-fueled cooker to a user-defined temperature level responsive to a first temperature signal measured within the cooking region of the solid-fueled cooker.

A home cooking appliance includes a housing having a rear exhaust exit, a cooking surface on top of the housing, the cooking surface having an upper surface, a cooking compartment in the housing, a cooling air system that conveys cooling air through the housing, an exhaust channel in fluid communication with the cooling air system and the rear exhaust exit, the exhaust channel for guiding a portion of the cooling air from the cooling air system to the rear exhaust exit, and an airflow metering device configured to control an airflow of the portion of the cooling air flowing at least one of into the exhaust channel and within the exhaust channel.
