Abstract:
A dishwashing machine has a load-bearing structure that comprises a base supporting a washtub (3), there being articulated to the load-bearing structure a front door (4) of the washtub (3), the machine (1) moreover having a system for extraction of damp air from the tub (3), which comprises a fan (7) and a discharge duct (8) having a hollow body (9) with a width dimension and a height dimension. The fan (7) is a radial fan having a fan housing (7a), housed in which is a centrifugal impeller (7b), and the discharge duct (8) has an inlet portion (10) and an outlet portion (11). The intake mouth (7c) of the fan (7) is in fluid communication with an outlet opening (15) of the tub (3), the inlet portion (10) of the discharge duct (8) is in fluid communication with the delivery (7d) of the fan (7) and the outlet portion (11) of the discharge duct (8) is at the front of the machine (1). The discharge duct (8) has a portion (12) intermediate with respect to the inlet and outlet portions (10, 11) having a height (H) that decreases towards the outlet portion (11) and a width (W) that increases towards the outlet portion (11). At least the outlet portion (11) and the intermediate portion (12) of the discharge duct (8) extend over an upper wall (3a) of the tub (3), with the outlet portion (11) above an upper edge of the door (4). The outlet opening (15) is formed in one of the upper wall (3a) and a stationary side wall (3 c) of the tub (3), with the fan housing (7a) that is mounted on the aforesaid wall with the respective intake mouth (7c) that is at the outlet opening (15) and is substantially coaxial thereto. The damp air is drawn in from the outlet opening (15) substantially in the direction of the axis (A) of the impeller (7b) and forced in a radial direction into the discharge duct (8), and then expelled from the outlet portion (11) at the front of the machine (1) above the upper edge of the door (4).
Abstract:
The present invention relates to an ironing appliance (1; Γ), in particular for household use, of the type comprising: an iron (10; 10') comprising a soleplate (11; 11 ') allowing to carry out traditional ironing operations, in particular on textile items; generator means (30; 30') for generating steam, said generator means (30; ' 30') comprising a tank (31; 3 Γ) adapted to contain a liquid and a filtering element (32; 32') associated with said tank (31; 31 ') for filtering said liquid. The invention is characterized in that said ironing appliance (1; 1 ') comprises a pump (33; 33') positioned between the tank (31; 31 ') and the filtering element (32; 32') to take the liquid from the tank (31; 3 Γ) and supply it to said filtering element (32; 32').
Abstract:
The present invention relates to a refrigerating appliance (1), in particular for household use, comprising: - a cabinet (10), which comprises at least a first (11) and a second side wall (12), a top wall (13) and a bottom wall (14); - a housing (20) adapted to define at least one internal compartment (21) in said cabinet (10) for storing foodstuffs. The invention is characterized in that said housing (20) forms one piece with said cabinet (10) and defines an interspace (22) with said cabinet (10) at said first side wall (11), second side wall (12), top wall (13) and bottom wall (14), said interspace (22) being adapted to receive a structure (30) made of insulating material.
