- the plane according to which the blowing unit 5 mainly extends is not horizontally arranged, but is tilted relative to a horizontal plane.
- the supporting elements 100 denoted with "HIGH” are mounted in a higher position than the supporting element 100 denoted with "LOW".
- one or more supporting elements 100 are located in respective recessed formed in the counterweight 8 mounted next to the blowing unit 5 ( figures 2 , 3 ).

- the drying system 10 is operated so as to withdraw wet air from the tub 3 through inlet 10a and provide dried hot air at the outlet 10b.
- the wet air flowing through the inlet 10a is first condensed by condenser 4; then the air passes through the blowing unit 5: the impeller 59 first, and then the conduit 512. In the conduit 512 the air is also heated. The dried and heated air is then fed back into the tub 3 through the connection conduit 6.
Description
- The present invention refers to a support element for a household appliance adapted to perform at least a drying cycle, such as a washing/drying machine or a drying machine.
- The present invention also refers to a household appliance adapted to perform at least a drying cycle, such as a washing/drying machine or a drying machine provided with said support element.
- Drying machines and washing/drying machines comprise a rotating drum in which the items to be dried are placed. The drum is rotatably mounted in a tub. To perform the drying through a recirculation line, the air is extracted from the tub, treated and reintroduced therein. The recirculation line includes:
- a condenser that causes the condensation of the moisture contained in the air extracted from the tub (such moisture is transferred to the air by the linen whilst it is drying);
- a blowing unit that moves the air along the recirculation line; the blowing unit typically comprises a fan (or impeller) and a casing, in which the fan is rotatably mounted;
- an element that heats the air before it is reintroduced into the tub.
- The casing is usually made of metal, such as for example stainless steel or aluminum.
- By contrast, the tub is usually made of plastic material.
- The Applicant noted that the casing of the blowing unit reaches high temperatures in working conditions, given to the flow of hot air that passes therethrough.
- Accordingly, heat might be transferred from the casing to the tub (which, as said, is made of plastic material), thereby locally melting or, in general terms, damaging the tub itself.
