Problems solved by technology

[0007] Unfortunately, when the motor spins at high speed, the centrifugal fan spins with the tub at high speed and blows air at a very high velocity inside the tub, which tends to separate the laundry from the inner tub surface, causing the laundry itself to move towards the laundry port. move gradually

Embodiment Construction

[0052] figure 1 The reference number 1 in the figure designates the rotatable drum laundry dryer as a whole comprising an external cabinet / housing 2 resting on the floor, preferably via several feet. The enclosure 2 is preferably designed to support a rotatable laundry drum 3 , which delimits a drying chamber 4 for laundry and preferably, but not necessarily, rotates about a horizontal axis of rotation 6 . (In alternative embodiments not shown, the axis of rotation 6 could be vertical or inclined)

[0053] The drying chamber 4 has a front entrance 7 which can be closed by a door 8 which is preferably hinged to the housing 2 .

[0054] exist figure 1 In an example, one open side of the clothes drum 3 is preferably associated with a perforated inner wall fixed to the side wall of the shell 2 in a rotatable and substantially airtight manner, and hot air is blown into the drum 3 through this open side. The other open side of the cartridge 3 is preferably associated in a rotatab...

Abstract

A laundry dryer (1) comprising: a laundry drum (3) designed to rotate around a longitudinal axis (6); an air recirculation duct (10) connected to said laundry drum (3); heating means (10) placed along the air recirculation duct (10) to heat the air flow; rotatable fan (11) placed along the air recirculation duct (10) to generate air flow through the barrel (3); fan (11) designed to rotate in the primary and secondary directions of rotation for generating different air flow rates; the motor (14), which is mechanically connected to the fan (11) and barrel (3) for making the fan (11) Rotating simultaneously with the drum (3); the household laundry dryer (1) is characterized by comprising an electronic control device (18) configured to control said electric motor (14) such that: a rotation speed (v1) causing the fan (11) to rotate in a main rotation direction for providing a first air flow rate; or the drum (3) in a counter rotation direction at a second rotation speed greater than said first rotation speed (v1) (v2) rotates, thereby causing the fan (11) to rotate in a secondary rotation direction for providing a second air flow rate lower than the first air flow rate.

Description

technical field [0001] The present invention relates to a rotatable drum type laundry dryer and a control method for controlling the rotatable drum type laundry dryer for drying delicate laundry. Background technique [0002] In particular, the present invention relates to a rotatable drum clothes dryer comprising: an outer casing; a cylindrical drum for containing laundry to be dried and arranged in an axially rotatable manner within the casing a door, hinged to the front of the shell, to rotate to close the opening in the front of the shell to seal the shell and the rest position of the drum and rotation from the rest position; a hot air generator designed to flow through the revolving drum (revolvingdrum) and over the clothes in the drum to quickly dry the clothes, with a low moisture content The hot air flow circulates within the drum across internal recirculation ducts. [0003] The rotatable tub clothes dryer also includes: a transmission fitting that rotates the tub...
