JPH0732839B2 - Lint filter attachment device for clothes dryer - Google Patents

Description

TECHNICAL FIELD The present invention relates to a device for attaching a lint filter to the inside of an air passage in a clothes dryer such as a dry cleaner.

(B) Prior Art An example of the dry cleaner disclosed in Japanese Utility Model Publication No. 61-77992 and Japanese Utility Model Publication No. 61-187219 will be described with reference to FIG.

Ventilation passage 30 communicating with a rotating drum that doubles as a washing tank and a drying chamber
Interior of the storage room 32 of the horizontal lint filter 31,
A communication port 34 to the blower 33 is provided. The dry air is circulated to the drum through the lint filter 31, the blower 33, the condenser, and the heating device.

The ventilation passage 30 is formed in the outlet 35 facing the storage chamber 32, and can be opened and closed by a lid. Storage room 32
Has a storage opening 36 facing the outlet 35, and the edge of the storage opening is curled to form a flange 37. In addition, the storage chamber 32 is provided with an engaging portion 38 that projects to the rear surface.

On the other hand, the filter 31 and its holder 39 are detachably attached to the storage chamber 32 via the outlet 35 and the storage port 36.

The holder 39 is a wire rod formed into a substantially cylindrical shape, and has a flange 40 that abuts the flange 37 formed in the opening and a hole into which the engaging portion 38 is fitted at the insertion end (bottom). There is.

The filter 31 has a bag-like shape, is mounted in the holder 39, and hangs an opening edge incorporating the ring-shaped spring 41 across both the flanges 37 and 40.

(C) Problem to be Solved by the Invention In the conventional example, the opening edge of the filter 31 is formed by the two flanges 37, 40.
It is necessary to put a hand into the narrow ventilation passage 30 from the take-out port 35 to hang it over the floor, and the workability is extremely poor. The same applies when removing the filter 31.

The present invention makes it possible to easily and surely attach and detach the filter.

(D) Means for Solving the Problems The present invention provides an air passage provided with an outlet, and a storage chamber that is disposed in the air passage and has a storage opening with a flange that faces the outlet. It has a cage with a flanged opening and is detachably inserted into the storage chamber through the outlet and the storage opening. In this inserted state, the flange on the opening side is the flange on the storage opening side. An opposing holder, a bag-shaped filter mounted in the holder, and having an opening edge wound around the flange on the opening side so as to cover the flange, and the storage port side in the filter. From the storage port side through the filter, the holding end is elastically pressed by the pressing end part, and the operation end part is elastically detachably fixed to the ventilation path wall on the outlet side. With a pressing tool The opening edge wound around the flange on the opening side is sandwiched between the flange on the storage opening side and the flange on the opening side.

(E) Action The filter is installed in advance in the holder and the opening edge is wrapped around the flange on the opening side of the holder. Then, the holder is inserted into the storage chamber through the outlet of the ventilation passage and the storage port of the storage chamber. After that, an elastic pressing tool is inserted into the filter from the storage opening side, and the holding tool is elastically pressed by the elastic pressing tool from the storage opening side through the filter. In this state, the operation end of the elastic pressing tool is detachably attached to the ventilation path wall.

By elastically pressing the holding tool with the elastic pressing tool, the opening edge of the filter wrapped around the opening-side flange of the holding tool is sandwiched between the storage port-side flange and the opening-side flange. It does not come off undesirably.

In addition, the filter is elastically pressed so that it spreads well toward the bottom of the holder.

(F) Example An example of a dry cleaner will be described with reference to the drawings. FIG. 1 shows a main part of a recovery tank attached to the cleaning / drying chamber. The recovery tank is configured to forcibly circulate dry air containing solvent vapor between the cleaning air and the drying chamber during drying, recover lint in the dry air during this time, and condense and recover the solvent.

1 is an inlet for introducing dry air from a cleaning / drying chamber (not shown) into the recovery tank, 2 is an outlet for facing the blower 3 and for delivering the dry air to a condenser and a heater (both not shown) And
The air passage 4 is between these two openings.

The ventilation passage 4 is provided with a lateral storage chamber 5, a lateral outlet 7 that is opened and closed by a lid 6, and a U-shaped receiver 8 located in the vicinity of the outlet. The storage chamber 5 is provided with a storage opening 10 with a flange 9 facing the outlet 7, and an engagement tool 11 located on the rear surface. A packing 12 is attached to the outlet side of the flange 9.

The holder 13 is a bottomed, substantially cylindrical net basket made of a metal wire, and has an opening having a larger diameter to form a flange 14 and an insertion port 15 at the bottom. And
Engagement tool 11 fits into insertion port 15 and flange 14 seals
Face to face 12.

The filter 15 preliminarily mounted in the holder 13 is formed by sewing a breathable cloth into a bag shape, and is wound so as to cover the opening edge 16 with the flange 14.

The elastic pressing tool 17 is formed by bending one end of one metal rod into a spiral shape having a larger diameter than the engaging tool 11 to form an elastic end (pressing end) 18, and bending the other end at a right angle. Also, fold it 180 degrees and operate it 1
Formed in 9. Then, the elastic end portion 18 is inserted into the filter 15 through the take-out port 7 and the storage port 10, and the filter 15
The bottom of the holder is pressed against the bottom of the holder 13 and the entire holder 13 is pressed, and the holder 13 is detachably fixed to the receiver 8 by rotating the holder 13 slightly. Then, the flange 14 of the holder 13 is elastically brought into contact with the packing 12 and the flange 9, and the opening edge 16 of the filter 15 is elastically sandwiched between the flanges 9 and 14.

When cleaning the filter 15 and the like, the operation end portion 19 is pivoted so as to be returned so as to be removed from the receiving tool 8, and the elastic pressing tool 17 is pulled out from the filter 15. Then, the holder 13 is placed in the storage chamber 5.
It is possible to take out every 15 filters from.

(G) Effect of the Invention According to the present invention, the filter can be installed in the holder in advance and the opening edge can be wrapped around the flange on the opening side of the holder, whereby the holder can be stored. In this state, it is possible to eliminate the need to put a hand into the narrow ventilation passage to work from the outlet of the ventilation passage, and therefore, the workability of attaching and detaching the filter can be significantly improved.

Furthermore, an elastic pressing tool is inserted into the filter from the storage opening side of the storage chamber, and the elastic pressing tool elastically presses the holding tool from the storage opening side through the filter, and the elastic pressing tool is wound around the opening side flange of the holding tool. Since the opening edge of the filter is sandwiched between the flange on the storage port side and the flange on the opening side, the opening edge of the filter is securely attached and does not undesirably come off.
