Abstract

PURPOSE:To regulate the direction of a thrust and prevent rubbing noise from being generated by forming radial bearing sections butted to the internal surface of the flange section of a rotary drum, and thrust bearing sections butted to the side surface, in U shapes, and by arranging a plurality of the bear sections on a bearing plate. CONSTITUTION:On the outer periphery of a bearing plate 30 for inscribing and supporting the opening flange section 29 of a rotary drum 25 pivotally, a felt 31 is bonded, and a plurality of U-shaped radial thrust bearings 32 are fitted. At the time of the rotation of the rotary drum 25, by the radial bearing sections 33 of the radial thrust bearings 32, the rotary drum 25 is positionally regulated in the radial direction, and thrust bearing sections 35 regulate the rotary drum in the thrust direction. As a result, the rubbing noise of the end surface of the flange section 29 of the rotary drum 25 butted to the bearing plate 30 is not generated.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a clothes dryer for general household use.

Conventional technology The configuration of a conventional clothes dryer is shown in FIGS. 3 and 4.

In the figure, 1 is an outer frame, and 2 is a motor provided within the outer frame 1. This motor 2 drives a rotating drum 5 and a fan 6 via belts 3 and 4, respectively. The rotation of the fan 6 causes a flow of air as indicated by the arrow a, and the hot air that has passed through the heater 7 dries the clothes 8 that are being rotated and agitated within the rotating drum 6 .

The rotating drum 6 has a substantially cylindrical open flange portion 9, and a felt 11 is attached to the outer periphery of a support plate 10 that internally and pivotally supports the flange portion 9, and a plurality of radial bearings 12 are provided on the outer periphery. pcs installed. This radial bearing 12 is provided on the upper side of the rotating drum 5, which is subject to a load, and prevents the felt 11 from becoming sagging over a long period of use, thereby ensuring airtightness for a long period of time.

Problems to be Solved by the Invention In such a conventional configuration, the position of the rotating drum 5 is restricted only in the radial direction by the radial bearing 12, and therefore, during rotation, there is no movement in the thrust direction (indicated by the arrow mark in FIG. 3). However, when the end surface of the flange portion 9 of the rotating drum 5 hits the support plate 1o, there are problems such as abnormal noises being generated.

The present invention has been made to solve these problems, and it is an object of the present invention to regulate the thrust direction of the rotating drum with a simple configuration.

Means for Solving the Problems In order to achieve the above object, the present invention provides a support plate that internally and pivotally supports a substantially cylindrical opening flange portion of a rotating drum, and a radial bearing portion that abuts the flange portion of the rotating drum and a rotary bearing portion. A plurality of radial-thrust bearings are arranged in which the thrust bearing portion that contacts the side surface of the drum is formed into a substantially U-shape.

Function: With this configuration, the radial direction and thrust direction of the rotating drum can be regulated with a simple configuration such as forming a substantially U-shaped bearing.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. In the figure, 21 is an outer frame, 22 is a motor, and the motor 22 drives a rotating drum 26 and a fan 26 via belts 23 and 24, respectively. The rotation of the fan 26 causes a flow of air as indicated by the arrow.
The hot air that has passed through the heater 27 dries the clothes 28 that are being rotated and agitated within the rotating drum 25 . The rotating drum 26 has a substantially cylindrical open-loop flange portion 29, and a felt 31 for improving airtightness is attached to the outer periphery of a support plate 30 that internally and pivotally supports this flange portion 29. A plurality of shaped radial thrust bearings 32 are attached. The radial thrust bearing 32 has a radial bearing part 33 that comes into contact with the inner surface of the flange part 29 of the rotating drum 26, and a thrust bearing part 36 that comes into contact with the side surface 34 of the rotating drum 26, and is formed in a substantially U-shape. ing.

According to the above configuration, when the rotating drum 26 rotates and rotationally agitates the clothing 28, the radial direction of the rotating drum 25 is regulated by the radial bearing part 33 of the radial thrust bearing 32, and the thrust bearing part 35 The thrust direction of the rotating drum 26 is also regulated and stabilized.

Therefore, it is possible to solve the conventional problem that the end surface of the flange portion 29 of the rotating drum 26 is connected to the support plate 30 and a scraping sound is generated. Furthermore, since the thrust bearing portion 36 only contacts the side surface 34 of the rotating drum 25, the durability of the entire bearing is not reduced, and the effect can be achieved even with a small number of radial thrust bearings 32. .

Effects of the Invention As is clear from the above embodiments, according to the present invention, it is possible to regulate the position of the rotating drum in the radial direction and the thrust direction with a simple configuration, and problems such as scraping noise due to the flange end face of the rotating drum 7 can be prevented. It can be prevented.
