JPS585600Y2 - Rotating drum clothes dryer door with filter - Google Patents

Description

[Detailed Description of the Invention] The present invention allows a filter to be easily attached to the back side of the door of a rotary drum type clothes dryer.

Referring to the drawings below, reference numeral 1 denotes a dryer having a clothes input port 2 on the front. drum 5
The drying drum 5 is supported by rotatably fitting the intake port 6 and the exhaust lower.

Reference numerals 8 and 8 indicate slip rings for making it easier to rotate this drum 5.

The drum support 4 is provided with a heater 9 made of a positive temperature coefficient thermistor in its center opening, and a guard plate is installed on the drum support 4 from the inside of the drum to prevent clothing from coming into direct contact with the heater. 10 is attached removably.

Note that this drum support 4 is attached to the back side of the dryer via a mounting plate 11.

Reference numeral 12 denotes a motor, and a blower 13 is attached to one end of the rotating shaft to suck air from an intake port 14, send this air to the heater 9 side, turn it into warm air, and blow it into the drying drum 5. There is.

A belt 15 is placed between the other end of the motor rotating shaft and the outer peripheral surface of the drum so that the drum 5 rotates slowly during drying operation.

Reference numeral 16 denotes a door that covers the clothes slot 2 so as to be openable and closable, and is provided with a ventilation hole 17 on the back side of the door.
Annular ribs 18 and 19 are integrally provided along the outer peripheral edge and inner peripheral edge of 7.

Reference numeral 20 denotes a filter unit that is detachably attached between the ribs 18 and 19, and includes a filter 21, a filter cover 22, and a gasket 23.

The filter cover 22 has an annular shape, has a large number of ventilation holes 24, and has holes on the inner periphery.
A cylindrical portion 25 is formed to fit into the inner annular rib 19 of the door, and the outer peripheral edge is bent toward the door 16, and the gasket 23 is fitted into the bent portion.

This gasket 23 is made of a flexible material, and has a lip portion 26 formed on its outer circumferential surface to create an appropriate amount of friction between it and the annular rib 18 to prevent the filter unit 20 from falling off during drying operation. At the same time, it is designed to be easy to put on and take off.

Further, a groove 27 is formed on the inner circumferential surface of the gas kerat 23 so that the outer circumferential edge of the filter 21 can be fitted into the groove. Positioning is performed by abutting against a protrusion 28 protruding from the top.

Furthermore, the filter cover 22 is attached to this gasket 23.
A curved seal part 29 is formed so as to wrap around the back side of the dryer, and when the door 16 is closed, this seal part abuts against the dryer main body side to prevent hot air from leaking from here.

Note that when the filter unit 20 is fitted into the annular rib 18 of the door, the filter 21 comes into contact with the stopper portion 30 protruding from the door, and the filter 21 is securely fixed.

As described above, in this case, since the filter unit 20 is attached to the back side of the door 16, this filter unit can be easily attached and detached and is convenient for cleaning. The filter unit 2
0 can be installed with appropriate friction.

Furthermore, since this filter unit 20 holds the filter 21 with a gasket 23 made of a flexible material, the filter 21 is removed from this filter unit.
You can easily remove the lint etc. attached to it, and the gasket 23 of the filter unit seals the door 16 and the main body side, so if you forget to attach the filter unit 20, It has various effects, such as the sound and feel when the door 16 is closed, and the ability to quickly notice if you have forgotten to put it on.
