Embodiment Construction

[0015] refer to figure 1 , shows a block diagram of the drying apparatus. The drying apparatus, also referred to as the dryer 100 , dries wet items such as laundry by circulating drying air through the wet items. The dryer 100 may include a support frame (not shown), a drum 104 , a blower 108 , a non-line frequency motor 112 , a heater 116 , and a controller 120 . The drum 104 as known in the art is typically a generally cylindrical device coupled to a support frame for rotation relative thereto. The drum 104 has an inner space for accommodating items such as laundry to be dried. In response to being driven by the motor 112, the blower 108 circulates air into the drum 104 and among the items. The heater 116 can be energized to heat the air circulated by the blower 108 . The controller 120 may control the amount of airflow generated by the blower 108 and the angular velocity of the drum 104 . Next, each element of the dryer 100 will be explained in detail.

Abstract

A drying device has been developed having a single electric motor configured to drive a drum and directly drive an air blower. The single electric motor is a non-line frequency electric motor. The drum is coupled to a support frame to enable rotation of the drum relative the support frame. The drum has an interior space for holding a load of articles, such as clothing. The motor includes a controller configured to regulate the angular velocity of the output shaft of the motor with reference to the current drawn by the motor.

Description

technical field [0001] The apparatus and methods described below relate to laundry appliances, in particular clothes dryers. Background technique [0002] Clothes dryers -- also known as laundry dryers -- dry wet laundry by circulating heated air through the clothes. Laundry dryers often include a drum in which a large quantity of wet laundry is placed. During the drying cycle, the motor rotates the drum and the blower circulates heated air through the laundry as it tumbles in the drum. The drying cycle may continue until a predetermined period of time has elapsed or until the control system determines that the laundry is substantially dry. [0003] An electric motor coupled to the drum contains an output shaft with a constant angular or rotational velocity. The rotation of the output shaft is typically coupled at one end to the drum by a drive train to give the drum an angular velocity suitable for most laundry drying situations, and at the other end to a blower that mov...
