Plastic carrier for a tumble dryer

The invention relates to a plastic support body for a Clothes dryer according to the preamble of the patent claim

DE-AS 25 59 987 already has a tumble dryer with a horizontally mounted drum perforated in the jacket, a hot air blower directed towards the outer surface and a support body for all parts of the Clothes dryer known, wherein the support body consists of a foamed thermoplastic, the lower half of the Enclosing the drum shell and provided with sliding surfaces for mounting the drum on parts of its outer surface and that in the support body as a supply air duct, fan housing and cavities serving for exhaust air ducts are formed. The fan housing consists of two parts; the one part is molded into the support body, the other part can be fitted with the fan wheel and with the support body by clips be releasably connected. The drum drive motor is arranged in the lower part of the support body. This the drum jacket on its lower half circumference enclosing and supporting the drum known support body has in the So far not proven in practice, because the relatively large foam part does not withstand the stresses in the long run. In addition, the known device requires large wall thicknesses.

The invention is based on the object of a plastic support body of the type mentioned to create the height of the base area of the tumble dryer is limited below the laundry treatment room, but all essential puncture elements of an air-cooled Condensation dryer takes up and is due to a simple structure and good accessibility the functional elements.

According to the invention, this object is achieved by the features solved in the characterizing part of claim 1. Advantageous further developments of the invention are set out in the patent claims 2 to 7 indicated.

Compared to the support body common in the tumble dryers on the market, which consists of a multi-part metal frame with several * angles. " Air ducts etc. have to be installed as individual parts in the support body, the invention creates a compact support body made of plastic, which forms a base for the dryer housing to be arranged above and in which a large number of the functional parts are already integrated Box that can withstand all loads. When the supporting body is tilted, the double fan with the fan motor can be brought in via the assembly opening. The motor for the drum drive is easily accessible between a corner post and a stand suspended along one side of the supporting body. The intermediate floor is firmly welded to the base part, the boundary walls of the base part for the air ducts, the condensate collecting chamber, the condenser receiving space, the fan spiral casing, the air guide vanes, etc. forming casing stiffeners. These enclosures allow reinforcements ndimg in the welded Ver'E _&: JGI £ 'ji <e i a false floor

The drying air, which is routed in a closed circuit and is used to dry the laundry, leaves the washing drum saturated with moisture and is passed into the condenser, for example via the drying air fan and a drying air duct 33. The drying air dehumidified in the condenser then flows back to the laundry drum via a connection duct 34- and a heater. The dry air blower and the cooling air blower together with a centrally arranged blower motor form a blower unit which stands in a vertical arrangement in the support body and can be installed through the installation opening 29 and a push-through opening 35 of the intermediate floor. The intermediate floor 19 can be connected to a motor position shield of the fan motor for holding the fan unit and for mutual sealing of the fans arranged one above the other.
