Description

  The present invention relates to a washer / dryer.

  Patent Document 1 describes, as a washing and drying machine, a configuration in which lint removal means for blowing a wind directly onto a door glass peripheral plate portion while blowing a wind directly onto clothes from an air blowing path is provided.

JP, 2010-246700, A

  However, since the conventional washing and drying machine described in Patent Document 1 is a method of removing dust such as lint generally referred to as “lint” by directly blowing wind directly on the door glass peripheral side plate, There is a possibility that lint may adhere to the door glass and the bellows because the wind is not blown to the diagonal side of the wind outlet.

  The present invention has been made to solve the above-mentioned problems, and its main object is to provide a washing / drying machine capable of suppressing the adhesion of lint to the discharge port diagonal side.

  In order to achieve the above object, according to the present invention, there is provided an outer tub having an opening for taking in and out clothes, and a laundry provided in the outer tub and rotationally driven by a motor and having an opening facing the opening of the outer tub. The drying air passage is provided with an inner tank to be accommodated, a bellows attached to the opening of the outer tank, a door for opening and closing the opening of the outer tank, and a drying mechanism having a heater, a fan and a drying air passage. An outlet includes an outlet for blowing a wind on the clothes in the inner tank, and a so-fu cover having a hole for blowing the wind toward the door and the bellows.

  According to the present invention, it is possible to provide a washing / drying machine capable of suppressing the adhesion of lint to the door glass and the bellows on the diagonal side of the outlet of the wind, by the wind passing between the door glass and the bellows.

<Principle of adhesion suppression>
FIG. 3 is a view of the outer tank cover 3b. The sou-fu cover 38 and the duct nozzle 39 are attached to the outer tank cover 3b. A wind α4 discharged from an oblique hole 52 (described later) provided on the cover surface 38a blows the wind toward the door glass 40 and the bellows 41, and the flow of the wind in the same arc of the door glass 40 peripheral plate portion and the bellows 41 So that the air can be blown across the diagonal of the so-fu cover 38.

  FIG. 4 is an enlarged view of the upper right portion B of the outer tank cover 3b. The wind α1 from the duct nozzle 39 is branched into the wind α2 from the oblique hole 52 of the so-fu cover 38 attached to the outer tank cover 3b and the wind α3 from the discharge port 51. The wind α1 flows from the blower unit (not shown) installed on the right side of the upper portion of the main body through the duct nozzle 39 into the saw cover 38, and the wind α2 is discharged from the side of the saw cover surface 38a from the diagonal hole 52 provided in the saw cover 38. It has become.

  The drum-type washing machine 1 has a blower unit (not shown), and the blower unit is composed of a driving fan motor (not shown), an impeller (not shown), and a fan case (not shown). ing. A fan heater (not shown) is incorporated in the fan case, and the fan heater (not shown) heats the air sent from the impeller. The dry air created by the air blowing unit installed at the upper part of the drum type washing machine 1 flows into the sofu cover 38 through the duct nozzle 39, and the wind α1 is blown from the discharge port 51 of the sofu cover 38 to the clothes in the inner tank 4 . The wind α3 blown to the inner tank 4 is passed through a duct (not shown) formed on the inner side of the outer layer 3 and flows in a circulating circulation path flowing into a blower unit installed on the right side of the upper portion of the main body. .

  FIG. 5 is a single-part view of the so-fu cover 38 attached to the outer tub cover 3b. (A) of FIG. 5 is a perspective view, (b) is a top view, (c) is a CC cross-sectional view of (b). The wind α1 flows toward the rear cover 38b which is in contact with the air passage 50 side. Then, the wind α2 is discharged from the plurality of oblique holes 52 provided on the so-called cover surface 38a. The wind α 2 blows between the door glass 40 and the bellows 41. The angle of the oblique holes 52 is not perpendicular but at an angle with respect to the cover surface 38a.

  FIG. 6 is an AA cross section of the outer tank cover 3b. The state which water-sealed the bellows 41 which is rubber packing for water sealing attached to the outer tank cover 3b with the door glass 40 is shown. A so-fu cover 38 is formed on the air passage 50 through which the wind α1 flows.

  FIG. 7 is an enlarged view of D of FIG. The wind α1 is shaped to flow so as to trace the back cover 38b. The wind α1 is branched into a wind α3 blowing on the clothes in the inner tank 4 and a wind α2 blowing between the door glass 40 and the bellows 41 from the diagonal holes 52 provided in the so-fu cover surface 38a.

  FIG. 8 is an enlarged view of part E of FIG. The wind α1 passes through the air passage 50 and becomes a wind α3 from the discharge port 51 and is discharged to the inner tank 4 so that the clothes in the inner tank 4 are blown by the wind. On the other hand, by providing the diagonal holes 52 in the sou-fu cover 38 located on the side of the air passage 50, the air flow α1 is branched to produce the air flow α2 blowing between the door glass 40 and the bellows 41.

  The wind α 2 blown between the door glass 40 and the bellows 41 follows the shape of the oblique hole 52 provided in the sou-fu cover 38 so as to trace the space between the door glass 40 and the bellows 41 to the door glass peripheral plate or It becomes wind α 4 passing in a circle centered on the center of 40. This wind α4 blows away lint and the like on the door glass 40 and the bellows 41 and promotes evaporation of the moisture adhering to the entire door glass 40 and the entire bellows 41 with heat and air flow, The adhesion of lint such as lint to the door glass 40 and the bellows 41 can be effectively suppressed.

  The oblique holes 52 allow the wind α2 branched from the wind α1 to flow in the same arc shape of the door plate 40 peripheral plate portion and the bellows. The oblique holes 52 allow the wind α 4 flowing in the same arc shape (along the circumference of the circular door glass 40) of the door glass 40 peripheral plate portion and the bellows to be blown to the diagonal position of the sou-fu cover 38.

  By providing a plurality of oblique holes 52, wind flow is generated at the time of branching of the wind α1, and the deceleration of the wind speed of the wind α4 flowing in the same arc shape as the door glass peripheral plate portion is suppressed. It becomes possible to blow the wind toward 41 without reducing the wind speed, and the following effects can be obtained.

  During drying, the faster the wind speed of the air blowing unit blows on the clothes, the faster the generated air flow. As a result, lint does not easily adhere to the door bellows, and lint that has once adhered to the door is also easily peeled off. In addition, the more time it takes for the clothes to dry and the drying operation to finish, that is, the time it takes for the wind to blow on the lint adhering to the door bellows 41 after the water droplets on the door bellows have dried during the drying process, However, the force for removing lint is more likely to act on the lint, making it difficult for the lint to remain.

  As described above, according to the drum-type washing machine 1 as the washing / drying machine according to the present embodiment, the lint adhesion can be suppressed.

  The present invention is not limited to the above-described embodiment, but includes various modifications. For example, the above-described embodiments are described in detail to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations. Further, part of the configuration of the embodiment can be replaced with another configuration, and another configuration can be added to the configuration of the embodiment. In addition, it is possible to add, delete, and replace another configuration for part of each configuration.
