This invention is an improvement over the machine of my Norwegian Patent No. 79,616, in that heating elements are provided between the water tanks.
The purpose of thisinvention is to provide a combination machine for washing, rinsing and drying clothes, dishes, and the like, wherein clothes, dishes and other products may be washed, rinsed and dried in a machine occupying comparatively little floor space and wherein the machine may also be used for supplying hot water for household use or may be used for heating and ventilating.
In the conventional type of washing machine of the agitator or rotary type it is possible for bunches of clothes'to remain, within certain limits, in a pocket or portion of a machine and with this type of washing machine it is diicult, if not impossible, to insert a tray of dishes, bottles, or other articles. For this reason it is substantially impossible to use a clothes washing machine for washing dishes or a dish washer for washing clothes. With this thought in mind this invention contemplates a combination machine of the rotary cylinder type wherein a basket of clothes positioned in the cylinder is adapted rto rotate with the cylinder wherea-s a basket of dishes placed in the cylinder remain stationary, and in which either clothes or dishes may be sprayed with soapy water for washing, clean water for rinsing, and air for drying.
The object of this invention is, therefore, to provide means for forming a washing machine wherein clothes, dishes, and yother objects positioned in the machine are subjected to soapy water for washing, clean warm water for rinsing, and air for drying.
Another object of the invention is to provide a combination washing, rinsing, and drying machine in which a plurality of batches of clothes may be washed with the same soapy water.
Another object of the invention is to provide a cornbination washing, rinsing zand drying machine in which handling clothes or other objects between the steps of washing, rinsing and drying is unnecessary.
A further object of the invention is to provide a combination washing, rinsing and drying machine which is of a -simple and economical construction.
With these and other objects in view the invention embodies a substantially rectangular shaped casing having an open compartment or chamber with asemi-circular lower surface therein'and with a cylinder positioned `to rotate in said chamber and adapted to receive baskets that rotate therewith or that remain stationary. The invention also includes Vmeans for rotating the cylinders means for supplying heated water or air to the cylinder arent Op i inthe end plate.
and means mounting the parts whereby the parts are readily removable and replaceable.
