Abstract

PROBLEM TO BE SOLVED: To solve the problem in which cleaning of a drying filter is difficult as a resin frame of the drying filter rubs with clothing during a drying operation and static electricity generates on the surface and lint adheres, and the lint adheres to the clothing in a drum.SOLUTION: By a frame body of a drying filter being constituted by a material having antistatic effects, lint adhering to the frame body of a lint filter during a drying operation is prevented, and lint adhering to clothing can be prevented and cleaning properties of the drying filter can be improved. Also, by mixing a master batch having antistatic effects with general-purpose resin, a material having antistatic effects can be achieved.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a clothes dryer.

  In a conventional clothes dryer, for example, as disclosed in Japanese Patent Application Laid-Open No. 2013-255331 (Patent Document 1), a lint collecting means (drying filter) is disposed inside the drum in order to collect lint generated during the drying operation. ).

JP 2013-223547 A

  In Patent Document 1, in order to simplify the area of the drying filter and to simplify the structure, the clothes dryer has a drying filter disposed in the drum. However, the dry filter consists of a resin frame and a mesh filter, but the resin frame rubs with clothes during the drying operation and static electricity is generated on the surface of the frame, so that lint adheres. There was a problem that the lint adhered to the clothes in the drum. In addition, there is a problem that it is difficult to care for the dry filter and time is required.

  Therefore, in order to solve the above problems, the frame of the dry filter is made of a material having an antistatic effect, thereby preventing lint from adhering to the frame of the lint filter during the drying operation. It is possible to improve lint adhesion prevention and dry filter care. Moreover, the material which has an antistatic effect is realizable by mixing the masterbatch which gave the antistatic effect to general purpose resin.

  In the clothes dryer of the present invention, it is possible to prevent lint from adhering to the frame of the lint filter during the drying operation, to prevent lint from adhering to the garment, and to improve the care of the dry filter.

  Hereinafter, the present invention will be described based on an embodiment shown in the drawings.

FIG. 1 is an overall configuration diagram of a clothes dryer. The rotating drum 2 constituting the drying chamber is rotatably disposed in the outer frame 1, and a heat source 3 for obtaining hot air for drying is disposed on the front surface of the rotating drum 2. The rotating drum 2 rotates by transmitting the rotating force of the electric motor 5 by the drum driving belt 4.
A drum air outlet 6 for discharging the drying air 7 is provided at the rear of the rotating drum, and the drying air and the cooling air 8 for cooling the drying air are generated behind the drum air outlet 6. A fan casing 10 that houses a heat exchange fan 9 that also serves as a heat exchanger and also serves as a heat exchange unit that cools the drying air 7 is disposed.

The fan casing 10 is divided into a drying air side and a cooling air side by a labyrinth seal portion 11a composed of concentric ribs attached to the outer peripheral portion of the heat exchange fan and a labyrinth seal portion 11b of the fan case lid 12. It has been.
The outlet for dry air of the fan casing 10 is communicated with the heat source 3 through an M duct 13 and an F duct 14.

  15 is a heat exchange fan drive belt, 16 is a heat exchange fan pulley, 17 is a heat exchange fan support member, 18 is a door that opens and closes an opening for putting in and out the object to be dried provided in front of the outer frame 1, 19 Is a drying filter, and 20 is a drum front fixing wall, on which the rotating drum 2 is rotatably fixed.

  The drying filter 19 is provided inside the drum. The drying air 7 that is disposed on the downstream side of the drum air outlet 6 and passes from the heat source 3 passes through the drying filter 7, thereby collecting lint generated from the clothes 24.

  The heat exchanging fan 9 includes a heat exchanging part 21, a sirocco fan part 22 that secures the air volume of the drying air, and a labyrinth seal part 11a that partitions the drying air and the cooling air. The heat exchanging portion 21 is constituted by a blade having a corrugated cross section, and performs heat exchange between the dry air and the cooling air via the blade surface.

  FIG. 2 is a configuration diagram of the drying filter. The dry filter 19 includes a plate-like filter 23 and a dry filter cover 22 that holds the filter.

  FIG. 3 is a configuration diagram of the drying filter cover 22, which has a lattice shape so as to allow drying air to flow while pressing the plate-like filter 23. This filter cover 22 is made of resin. By mixing this resin with a general-purpose resin and a master batch having an antistatic effect and molding it by injection molding, the filter cover 22 has an antistatic effect, so Prevent adhesion.

  FIG. 4 is a configuration diagram of the filter 23, which includes a mesh-like filter sheet 23b for collecting lint and a filter frame 23b for fixing the filter sheet 23b. The filter frame 23b is also made of resin. By mixing a general-purpose resin and a master batch having an antistatic effect and molding by injection molding, the filter frame 23b has an antistatic effect and prevents lint from adhering. .

  By mixing an antistatic material such as a masterbatch with the filter cover 22, the electrostatic charging voltage generated on the surface is reduced. On the other hand, the antistatic effect decreases when heat is applied (charging voltage increases). However, by containing at least about 10% of the master batch in the filter cover 22, it is possible to prevent the antistatic effect from decreasing even when heat is applied. Here, the content rate of said masterbatch is a ratio of the weight which a masterbatch occupies among the resin which comprises a filter cover, and the weight of a masterbatch.

  As described above, according to this embodiment, the frame body of the dry filter is made of a material having an antistatic effect, so that the lint is prevented from adhering to the frame body of the lint filter during the drying operation. It is possible to prevent lint adhesion and improve the care of the dry filter. Moreover, the material which has an antistatic effect is realizable by mixing the masterbatch which gave the antistatic effect to general purpose resin.
