Abstract

PURPOSE:To prevent the washing from wetting by preventing the formation of waterdrops on the inner surface of a cover through applying sandblast processing or sand paper processing to the inner surface of the cover for opening and closing the first opening of a horizontal shaft-type drum and a frame. CONSTITUTION:An opening 14 is formed in the central part of the top face of the frame 12 of a drum-type washing dryer and a cover-receiving face 18 for receiving an upper cover 16 is formed in the periphery of the opening 14. A groove 44 for collecting water at the time of opening the upper cover 16 is formed in the inner surface of the fitting part 42 of the upper cover 16 and sandblast processing or sand paper processing is applied to the whole inner surface of the fitting part 42. Water scattered by the rotation of the drum 52 adheres to the inner surface of the upper cover 16 and, in drying, water vapor generated in the drum 52 is cooled into water by the inner surface of the upper cover 16, but the inner surface of the upper cover 16 is made coarse and therefore large in contact area with water so that no waterdrops are formed there. Also, there is no possibility of waterdrops falling and wetting the washing at the time of opening the upper cover 16, because water excessively adhering to the inner surface of the upper cover 16 is collected in the groove 44.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum type washer / dryer, and more particularly to a drum type washer / dryer equipped with, for example, a horizontal shaft type drum and used for washing, dehydrating and drying.

[0002]

2. Description of the Related Art A conventional drum type washer / dryer 1 includes, as shown in FIG. 4, a frame 3 having an opening 2 on its upper surface. A substantially horizontal axis cylindrical outer tub 4 is supported inside the frame 3, and a horizontal axis drum 5 is rotatably supported inside the outer tub 4. A lid 6 having a smooth inner surface was attached to the opening 2.

[0003]

In the conventional drum type washer / dryer 1, since the inner surface of the lid 6 is smooth, water droplets are easily formed on the inner surface of the lid 6 in each of washing, dehydration and drying steps, and the lid 6 When opened, there was a problem that water drops might drop and wet the laundry after dehydration or drying.

Therefore, a main object of the present invention is to provide a drum type washer / dryer capable of preventing the laundry from getting wet.

[0005]

According to the present invention, there is provided a frame having a first opening, an outer tank supported in the frame and having a second opening communicating with the first opening, and rotatably supported in the outer tank. A drum type washer / dryer having a horizontal shaft drum and a lid for opening and closing the first opening, wherein the inner surface of the lid is sandblasted or sandpaper treated.

[0006]

When the inner surface of the lid is roughened by sandblasting or sandpaper treatment, the contact area with water increases, so that no water droplet is formed on the inner surface of the lid.

[0007]

According to the present invention, since water droplets can be prevented from being formed on the inner surface of the lid, the water droplets do not drop even when the lid is opened, and therefore, wetting of the laundry can be prevented. The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

[0008]

1 and 2, a drum type washer / dryer 10 of this embodiment includes a frame 12 having a substantially casing shape. An opening 14 (FIG. 3) is formed in the center of the upper surface of the frame 12.
A lid receiving surface 18 is formed at the peripheral edge of the opening 14 so as to receive the upper lid 16 from the upper surface of the frame 12 by one step. Further, an operation panel 20 on which selection keys of a washing program and the like are arranged, a power switch 22 (FIG. 1) and the like are arranged on a peripheral edge of an upper surface of the frame 12, and a hot air duct 24 inside the frame 12 is arranged on a side surface. A filter outlet 28 and the like for taking out the movable filter 26 provided in the above are formed. The upper lid 16 and the lid 30 are attached to the opening 14 and the filter outlet 28, respectively.

As can be seen from FIG. 3, the upper lid 16 is
A body 32 is included, and one end of the body 32 is attached to the frame 12 via a hinge 34. The lid lock device 36 provided on the frame 12 is provided on the inner surface of the other end of the main body 32.
An engaging portion 38 that is engaged with is formed at the center of the inner surface of the main body 32, and a fitting portion 42 that fits with a connecting member 40, which will be described later, fixed to the inner peripheral edge of the opening 14 is attached. A groove 44 for storing water when the upper lid 16 is opened is formed on the inner surface of the fitting portion 42.
The entire inner surface of 2 (including the groove 44) is sandblasted or sandpaper treated.

As can be seen clearly from FIG. 2, a substantially horizontal cylindrical outer tub 48 having an opening 46 at the top thereof is supported inside the frame 12, and the opening 46 of the outer tub 48 and the opening 14 of the frame 12 are supported. And are connected by a connecting member 40 made of rubber or the like. A packing 50 that seals the outer peripheral surface of the fitting portion 42 is formed on the inner periphery of the upper end portion of the connection member 40.

Inside the outer tank 48, a drum 52 made of stainless steel or the like and having a substantially horizontal axis is provided with rotating shafts 54a and 54a.
It is rotatably supported via b. An opening (not shown) for loading and unloading the laundry is formed on the peripheral side surface of the drum 52, and a baffle 56 or the like for scraping the laundry at the time of washing and drying is formed on the inner surface of the drum 52.

With the drum 52 supported in the outer tub 48, one rotating shaft 54b of the drum 52 is projected to the outside from the side surface of the outer tub 48, and the drive pulley 60 is attached to the protruding portion 58.
Is attached. A motor 62 is arranged below the outer tub 48, and a small pulley 66 is attached to an output shaft 64 of the motor 62. Then, the drive pulley 60 and the small pulley 66 are connected by the belt 68, whereby the power of the motor 62 is transmitted to the drum 52.

In operation, when a washing->dewatering-> drying program is executed by the washing program selection key on the operation panel 20 (FIG. 1), washing water is supplied into the outer tub 48 at the time of washing, and the drum 52 is driven by the motor 62. About 50
The laundry in the drum 52 is repeatedly reversed at rpm, scraped up by the baffle 56 and dropped from the upper side to the lower side, so-called tap washing is performed. Outer tank 4 for dehydration
The washing water in 8 is drained and the drum 5 is driven by the motor 62.
2 is rotated in one direction at about 800 rpm, and the laundry in the drum 52 is centrifugally dehydrated. And when dried,
The motor 52 rotates the drum 52 at about 55 rpm, and at the same time, the warm air is blown from the warm air passage 24 into the drum 52.

At the time of washing and dehydrating, the water splashed by the rotation of the drum 52 adheres to the inner surface of the upper lid 16, and at the time of drying, the water vapor generated in the drum 52 is cooled on the inner surface of the upper lid 16 to become water, and the upper lid 16 The inner surface of the is always wet. However, according to this embodiment, since the inner surface of the upper lid 16 is roughened by sandblasting or sandpaper processing and the contact area with water is large, water droplets are not formed on the inner surface of the upper lid 16. Further, when the upper lid 16 is opened, water excessively attached to the inner surface of the upper lid 16 will not be absorbed by the groove 4
Stored in 4. Therefore, there is no concern that the laundry will get wet due to a drop of water or the like.

Further, according to this embodiment, when the upper lid 16 is closed, the outer peripheral surface of the fitting portion 42 is sealed by the packing 50, so that the leakage of water vapor that occurs during drying can be reliably prevented.
