Housing for receiving contaminated airflow from a clothes dryer or from a building's interior, constructed for filtering and recycling thru an interior piping system or disposing out to a building's exterior and comprising a safety mechanical shutdown system of the clothes dryer

Abstract

Listed are some of this invention's unique features for producing a healthier home and a safer clothes dryer vent within the same housing system, which may be installed within a typical wall system or as a free-standing unit in a laundry room.

Included are two airflow receiving ports that accepts airflow from a clothes dryer or optionally from a house's interior rooms and two airflow exhaust ports that discharge the same airflow into an exhaust pipe to the outside or optionally into the building interior as recycled airflow.

A drainage device removes water derived from condensate which forms in the exhaust pipe and otherwise flows back into the housing.

Two (2) receiving ports and the two (2) exiting ports combine to provide four (4) combinations of airflow management.

The choice of which of the four (4) airflow ports are activated for airflow passage is subject to a selection from a control system which contains switches for the desired airflow management thru the housing.

Additionally, an exhaust system constructed to select airflow destinations, first destination, airflow can be directed to exit to the building's outside atmosphere or second destination, airflow can be directed to exit into an interior duct system for recycling of the filtered airflow.

Additionally, the control system contains monitors and sensors to indicate unsafe temperatures, air pressure changes or filter blockage within the housing.

A shutdown mechanism within the control system stops the airflow exhaust fan and stops the clothes dryer to provide an additional measure of safety.

Included in the invention is a multi-filter filtration system that includes filters that block lint particulate from a clothes dryer and block indoor pollutants comprising pre-filters, True HEPA filters, with activated carbon filters and air cleaners to meet EPA Indoor Air Quality Standards and MERV Ratings.

A multi-speed airflow exhaust fan moves airflow in thru the receiving ports, thru the multi-filters and out thru the exiting ports. Additionally, within the housing, access openings with removable windows provide internal inspections and accessibility.

In conclusion the elements of this invention combine to improve the efficiency and safety of a clothes dryer's exhaust system and improve the indoor air quality of a home or commercial building.

BACKGROUND

[0766] A typical clothes dryer works by forcing moist hot air with a degree of excess lint out into vent piping with no means of separating the moisture laden air from the excess lint, when the warm moist dryer air within the dryer vent reaches a space such as a garage, attic or outside atmosphere, colder temperatures cause the relative humid air to condense back to liquid form of water within the vent pipe.

[0767] This water can drain back into the clothes dryer or settle in a low point of the dryer vent causing blockage and overheating of the dryer, which can result in fire.

[0768] A full load of wet clothes can contain as much as 1.5 gallons of water, which can blend with lint and over time develop into a sludge within the vent causing blockage.

[0769] It has been estimated that there are about 2,900 clothes dryer related fires and 238 million in property loss per year.

[0770] This invention relates to solving this clothes dryer problem.

[0771] Additionally, there are no sensors within a clothes dryer vent system that communicates to shutdown a clothes dryer's electrical system when its vent piping becomes blocked, resulting in overheating and possible fires.

[0772] This invention relates to solving this clothes dryer problem.

[0773] Additionally, a typical clothes dryer vent pipe has no means to drain away the water derived from condensation within the vent pipe before it drains back down into the dryer's flexible vent or into the dryer itself.

[0774] This invention relates to solving this clothes dryer problem.

[0775] Additionally, a typical clothes dryer's placement tight to a wall causes the flexible vent to be crushed or kinked resulting in reduced airflow passage and trapped water in the deformed area of the flexible vent, causing blockage and overheating.

[0776] This invention relates to solving this clothes dryer problem.

[0777] Indoor pollution of a typical house is often 2 to 5 times higher than typical outdoor concentrations. Americans, on average, spend a great deal of their time indoors. People who are often susceptible to the adverse effects of pollution (e.g., the very young, older adults, people with cardiovascular or respiratory disease) tend to spend even more time indoors. The air exchange rate with the outdoors is an important factor in determining indoor air Pollutant concentrations.

[0778] Another effective way to improve indoor air quality are to reduce or remove the sources of pollutants and to ventilate with clean outdoor air or with recycled indoor air thru air cleaners and engineered filters designed for improving indoor air quality.

[0779] This invention relates to solving this indoor air-quality problem

[0780] Often indoor air quality issues have been addressed by placing portable air cleaners in the middle of a room or house, resulting an undesirable and unsightly addition to otherwise desirable room layouts.

[0781] This invention relates to solving this indoor air-quality problem

[0782] Another attempt to solving the indoor air quality problem has been to upgrade the air filter in the central-air furnace or central air-conditioning (HVAC) system.

[0783] Often, the heating/AC system operates only a percentage of the time in Winter and Summer and can be completely non-operational in the Fall and Spring when outside temperatures are mild, and heating and air-conditioning are not required.

[0784] This invention relates to solving this indoor air quality problem.

[0785] It is the belief that this invention can make a house better by addressing clothes dryer venting and safety problems, and by making the interior of a house healthier by improving the indoor air quality in an efficient manner.

CONCLUSION, RAMIFICATIONS AND SCOPE

[0786] Accordingly, the reader will see that the housing can be of multiple sizes and shapes to engage with a verity of clothes dryer configurations, it can be free standing, inserted within building walls or elevated.

[0787] The control system, and its elements can be a component of a computer system and programed to operate as a smart airflow processing system.

[0788] An extended piping system communicating with the receiving ports and the exit ports for circulating airflow throughout the building when in the building's interior airflow circulation mode.

[0789] The airflow fan may be of current designs or of future designs to meet the specific design requirements of this invention.

[0790] The damper door actuators of this invention may also be of current design or of future designs to meet the specific design requirements of this invention.

[0791] The removable airflow filter assembly can have other airflow filtering and airflow cleaning components of different specifications to meet the filtering requirements, including but not limited to removing radon, mold, volatile organic compounds (VOC), natural and unnatural odors.

[0792] The removable airflow filter assembly may comprise filtration components for any air-carrying contamination currently known and any future air-carrying contamination not currently known. Although the descriptions above contain many specifications, these should not be construed as limiting the scope of the embodiments but as merely providing illustrations of some of the presently preferred embodiments.

[0793] Thus, the scope of embodiments should be determined by the appended claims and their legal equivalents, rather than by the examples given.
