ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a fireplace ash removal system. More particularly, it refers to a vacuum unit used to suck ash through a pipe from a residence fireplace to a container located outside the residence.
It is common for a residence to contain one or more fireplaces for the pleasure of their occupants. Unfortunately, the ash, produced by wood burning fireplaces which are the most popular, causes a nuisance problem in disposal. A motor driven auger as described in U.S. Pat. No. 4,074,680 can drive the ash down to a pit located below the grate. The ash still has to be eventually removed from the ash pit. In U.S. Pat. No. 4,096,848, a basementless house has an ash removal system in which an auger extends under a floor to an ash removal pit at a side of a house. Although these systems assist in the disposal of ash, they still require the householder to deal with ash disposal. A system is needed which will remove ash without the need for further handling by the householder.
SUMMARY OF THE INVENTION
The invention herein described and claimed solves the prior problem of handling cold ash by providing a fully automatic system for transporting the ash from a fireplace directly to a closed container without the need for actuating an auger. The container can be disposed of without the need to deal with ash.
One or more fireplace hearths or a brick pizza oven is connected through a bottom grate and a funnel shaped ash hopper to a pipe conduit leading under a building slab to an outside area where a motor driven vacuum unit including a canister for retaining cold ash is located. The motor is electrically driven by actuating a switch inside the building or outside the building. A solenoid operated fresh air inlet is closed when the motor is creating a vacuum and open to emit fresh air to the system when the motor is not operating.
