This is the device that uses airflow to remove toilet odor, comprising a compressed air tube and a pipe. The compressed air tube blows air along the axis of a pipe, creating the high speed airflow inside the pipe, drawing the air behind to enter into and flow in the direction of the pipe, also drawing the toilet odor away. The embodiments in this application also describe a long pipe where both ends of the long pipe separately placed, with one end located at the area of concentrated odor, and the other end located at an area where the odor may be released, and a compressed air tube blowing air along the axis of the long pipe as a method to be able to remove odor.

A system and method for controlling activation and deactivation of an exhaust system for ventilating an enclosed space, such as a bathroom. The system includes a humidity sensor, a memory element, and a processing element. The sensor measures a humidity value in the space, and the memory element stores that value along with a series of previously measured humidity values. The memory also stores a look-up table which specifies activation and deactivation criteria for the exhaust system based on the measured humidity value and a normal humidity value. The processing element calculates the normal humidity value based on a weighted average of the stored series of humidity values, consults the look-up table, and controls the exhaust system as specified by the look-up table. The measured humidity value is added to the stored series of values at a first interval, and the normal humidity value is re-calculated at a second interval.

Certain exemplary embodiments can provide a system, which comprises a turbine wheel assembly. The turbine wheel assembly comprises a turbine wheel compartment. The turbine wheel compartment is constructed to be coupled to a fan. The fan can be coupled to a cartridge. The turbine wheel compartment is coupleable to a toilet fill valve assembly such that the turbine wheel assembly is housed within a toilet tank. The turbine wheel assembly comprises a turbine wheel.

A fluid removal system includes an operative sub-system, such as an ultraviolet (UV) light sanitizing system, that is configured to operate according to an operative cycle, such as a sanitizing cycle, and is configured to output an activation signal during the operative cycle. An actuator is operatively coupled to the operative sub-system and moveably connected to a fluid removal conduit. The fluid removal conduit is closed when the actuator is in a closed position, and opened when the actuator is in an open position. The actuator moves into the open position in response to the operative sub-system outputting the activation signal. Fluid, such as ozone, within a confined space is drawn into the fluid removal conduit when the actuator is in the open position and exhausted through an exhaust port.

Afforded are: a toilet body including a toilet bowl part, a rim conduit 36, and a rim part; and a functional component mounted on an upper surface part of the toilet body, rearward of the toilet bowl part. The upper surface part includes a cut-out part formed such as to be recessed downward from the other part of the upper surface part. The functional component is disposed on the cut-out part such as to be partially positioned downward with respect to an upper surface of the rim part, and such as to be partially stuck out into the toilet bowl part from upon the cut-out part, and, on a bottom surface of the stuck-out part, the functional component is provided with a conduit forming surface serving as an upper surface of the rim conduit.

A gas detection system includes a first sensor unit that outputs a voltage corresponding to a concentration of a specific gas, a storage tank capable of storing a sample gas or a purge gas to be supplied to the first sensor unit, and a control unit. The control unit detects a type and a concentration of a gas contained in the sample gas on the basis of a detection result of the first sensor unit. The control unit sets a collection period during which a gas in a predetermined space is collected into the storage tank as the sample gas or the purge gas and a supply period during which the sample gas or the purge gas is supplied to the first sensor unit such that the collection period and the supply period fall in different time slots.
