Abstract
A paint spray booth, which can also be utilized as a paint drying oven is disclosed and is especially suitable for use in businesses, such as automobile repair shops, to both paint and quickly bake the paint so that the number of automobiles that may be handled in a given time is increased significantly. The booth-oven comprises an enclosure which has a single air supply fan for moving air though the booth-oven. Preferably, the booth-oven has, in addition to a direct heater, a heat exchanger for more economical operation, and/or may be provided with an air recirculating system for additional savings. The booth-oven is structured so that paint laden air generated during the paint spraying operation is routed around or away from the heat exchanger.
Claims26
A paint spray booth-paint baking oven unit in which an article may be first paint sprayed and then the newly painted article subsequently baked, comprising a single enclosure generally isolated from the environment which functions both as a paint spray booth and subsequently as a paint baking oven, an inlet air supply for said single enclosure, a separate air heater outside of said single enclosure for heating the air supplied to said single enclosure from said inlet air supply when said single enclosure is used as a paint baking oven, and a single air moving fan for moving the air from said inlet supply through and out said enclosure when said single enclosure is used as a paint spray booth and also through said air heater when said single enclosure is used as a paint baking oven, whereby only a single fan is used to supply air to said single enclosure when it functions both as a paint spray booth and also to supply heated air when it subsequently functions as a paint baking oven.
A paint spray booth-paint baking oven unit in which an article may be first paint sprayed and then the newly painted article subsequently baked, comprises an enclosure generally isolated from the environment, an inlet air supply for said enclosure, a heater for heating said enclosure, a single air moving fan for moving the air from said inlet air supply through and out said enclosure, heat exchanger means for recovering the heat from the air being exhausted from the enclosure, by-pass means for routing paint laden air around said heat exchanger when the booth-oven is used for spray painted, and automatic damper means for by-passing the heat exchanger when the booth-oven is used for spray painting, whereby only a single fan is used to supply air to said enclosure when it functions as a paint spraying booth and also when it subsequently functions as a paint baking oven.
A paint spray booth-paint baking oven unit in which an article may be first paint sprayed and then the newly painted article subsequently baked, comprises an enclosure generally isolated from the environment, an inlet air supply for said enclosure, a heater for heating said enclosure, a single air moving fan for moving the air from said inlet air supply through and out said enclosure, said booth-oven operating at a pressure different from the environment, said enclosure having at least one closeable opening of an air lock construction, said enclosure having a second closeable opening for passage of the articles to be painted, said single fan drawing air from said heater, the air from said heater being supplied to the top of said enclosure, the air being withdrawn from the bottom of said enclosure, a heat exchanger means for recovering the heat from the air being discharged from the enclosure, by-pass means for routing paint laden air around said heat exchanger means when the booth-oven is used for spray painting, automatic damper means for by-passing said heat exchanger means when the booth-oven is used for spray painting, and air filtering and conditioning means for treating the air supplied to the booth-oven, whereby only a single fan is used to supply air to said enclosure when it functions as a paint spraying booth and also when it subsequently functions as a paint baking oven.
In a paint spray booth-paint baking oven unit in which an article may be first paint sprayed and then the newly painted article subsequently baked, having an enclosure generally isolated from the environment, an air supply for said enclosure, and a heater for heating the air supplied to said enclosure, the improvement comprising only a single air moving fan for moving the air from said air supply through and out said enclosure, heat exchanger means for recovering the heat from the air being discharged from the enclosure, by-pass means for routing paint laden air around said heat exchanger means when the booth-oven is used for spray painting, automatic damper means for by-passing said heat exchanger means when the booth-oven is used for spray painting, and air filtering and conditioning means for treating the air supplied to the booth-oven, whereby only a single fan is used to supply air to said enclosure when it functions both as a paint spray booth and when it functions as a paint baking oven.
