Abstract
An indoor gardening appliance includes a liner defining a grow chamber and a grow module rotatably mounted within the grow chamber for receiving a plurality of plant pods. A recirculation duct is in fluid communication with the grow chamber and a fan assembly circulates a flow of air through the recirculation duct and the grow chamber. A gas sensing assembly includes a gas sensor positioned within the recirculation duct for detecting the concentration of a gas within the flow of air and a flow stabilization device at least partially surrounding the gas sensor for reducing pressure fluctuations in the flow of air and improving gas sensor accuracy.
Claims17
A gardening appliance, comprising:
- a liner positioned within a cabinet and defining a grow chamber;
- a grow module mounted within the liner and defining a plurality of apertures for receiving one or more plant pods;
- a recirculation duct in fluid communication with the grow chamber;
- a fan assembly operably coupled to the recirculation duct for urging a flow of air through the recirculation duct;
- and
- a gas sensing assembly comprising:
- a gas sensor positioned within the cabinet for detecting a concentration of a gas within the flow of air;
- and
- a flow stabilization device surrounding the gas sensor for reducing pressure fluctuations in the flow of air, wherein the flow stabilization device comprises a muffler housing defining a sensing chamber and an intermediate muffler chamber, wherein the gas sensor is positioned within the sensing chamber, and wherein the muffler housing defines a muffler inlet that fluidly couples the intermediate muffler chamber to the recirculation duct and a muffler outlet that fluidly couples the intermediate muffler chamber to the sensing chamber.
A gas sensing assembly for an appliance, the appliance comprising a cabinet defining a chamber, a recirculation duct in fluid communication with the chamber, and a fan assembly operably coupled to the recirculation duct for urging a flow of air through the recirculation duct, the gas sensing assembly comprising:
- a gas sensor positioned within the cabinet for detecting a concentration of a gas within the flow of air;
- and
- a flow stabilization device surrounding the gas sensor for reducing pressure fluctuations in the flow of air, wherein the flow stabilization device comprises a muffler housing defining a sensing chamber and an intermediate muffler chamber, wherein the gas sensor is positioned within the sensing chamber, and wherein the muffler housing defines a muffler inlet that fluidly couples the intermediate muffler chamber to the recirculation duct and a muffler outlet that fluidly couples the intermediate muffler chamber to the sensing chamber.
