Definitions
- the present invention relates broadly to the same combination of elements i.e. a furnace and a laundry dryer, the purpose, construction, and mode of operation is substantially different.
- I provide a means for adding humidity to a building being serviced by a forced air heating system by selectively permitting moisture laden air from a clothes dryer to pass into the cold air return of the heating system.
- I provide a suitable control mechanism for causing the moisture laden air from the laundry dryer to pass outside of the building rather than to the cold air return if desired.
- Another object of this invention is to provide a simple and inexpensive mechanism which can be used to interconnect a conventional clothes dryer to the cold air return of a forced air heating system so that humidity can be introduced into the building.
- FIG. 1 there is shown a conventional laundry dryer having a cabinet 12 surrounding a motor driven cylindrical tumbler (not shown). Clothes to be dried are introduced through the door 14 into the tumbler chamber. Also contained within the dryer cabinet 12 is a heating unit which may be either electrical or gas burning type. The temperature of the heating unit may be controlled by a thermostat having an adjustable control lever 16. The drying time for the unit may be controlled by a settableclock controlled switch 18.
- a motor driven fan which causes air to pass over the heating unit where it becomes heated and from there through the drying chamber and a lint filter to an exhaust port which may be located on the rear of the dryer 10.
- the exhaust port of the dryer is connected by way of a cylindrical duct which leads to the outside of the building in which the dryer is located. Thus, moisture laden air is conveyed to the outside atmosphere.
- a forced air heating system indicated generally by the numeral 20.
- This forced air heating system is quite conventional and includes behind the removable panel 22, a motor and a squirrel cage blower driven by the motor.
- This motor driven blower draws air from various points in the building serviced by the heating unit through the cold air return 24 and a furnace filter 26 to a hot air plenum 28.
- the heating unit which may comprise a gas fired burner unit (not shown). The heated air is forced by the motor driven blower out of the hot air plenum 28 and through the building's hot air ducts (not shown) in a conventional manner.
- my invention contemplates connecting the exhaust port of a laundry dryer to the cold air return of the buildings heating unit. Hence, the somewhat heated and moisture laden air can be introduced into the building through the forced air heating system.
- a cylindrical duct 32 which is connected at one end to the exhaust port (not shown) of the dryer and at its other end to a junction box 34.
- the junction box 34 contains a damper or butterfly valve 36 which can be pivoted to block the opening of an exhaust duct 38 or the furnace inlet duct 40.
- the furnace inlet duct 40 is, in turn, connected to the cold air return 24 of the heating unit 20.
- the exhaust duct 38 is arranged to pass outside of the building so that when the damper 36 is in a position blocking the inlet to duct 40, the dryer system works in a conventional fashion to exhaust all of the moisture laden air to the outside atmosphere. However, when the damper 36 is rotated so as to block the exhaust duct 38, the moisture laden air from the dryer passes through the junction box 34 and through the duct 40 to the cold air return of the furnace.
- a suitable sensor for detecting when moisture laden air from the dryer is passing through the duct 40.
- I merely provide a vane type switch 42 which is disposed in the duct 40. When air flows through the duct 40 the contacts of the vane switch 42 close and are used to complete an electrical circuit from a power supply to the motor which drives the fan in the heating unit 20. This control insures that whenever moisture laden air from the dryer is being introduced into the cold air return of the heating unit, that the furnace blower will be operational to circulate this moisture laden air throughout the building.
- Apparatus for adding humidity to a building comprising in combination:
- a laundry dryer of the type including a heat source, a chamber for receiving moisture laden articles and a fan for directing air from said heat source through said chamber to an exhaust port;
- a forced air heating system having a furnace for heating air, a network of heating ducts, a cold air return and a motor driven blower for forcing said heated air through said network of heating ducts and said cold air return;
- control means responsive to the operation of said laundry dryer for energizing said motor driven blower and d. means connecting said exhaust port to said cold air return of said forced air heating system for conveying said moisture laden air to said furnace.
- control means includes a damper disposed between said exhaust port and said cold air return of said forced air heating system for controlling the flow of moisture laden air to said cold air return.
- control means includes means responsive to the flow of air in said means connecting said exhaust port to said cold air return of said forced air heating system for controlling the energization of said motor driven blower.
- Apparatus as in claim 1 further including means for selectively directing said moisture laden air outside of said building or into said cold air return.
