The present invention relates to a drum type washing machine that effectively removes moisture during dehydration of laundry.

The invention of Japanese Patent Application No. 2005-18329, filed on January 26, 2005 by the present applicant with respect to this type of drum type washing machine, shows the configuration of a rotating tub as shown in FIG. ), A laundry inlet 57 is provided on the front side of the housing body. The water tank 60 forming an outer shape is cylindrical and is elastically supported through the support device 61 inside the housing body 52 so that the front is raised substantially horizontally in the front-rear direction, and the water tank 60 The drum 66 is rotatably installed in the interior thereof, and is rotated by a motor 67 mounted on the rear surface of the water tank 60.

The door 58 for opening and closing the inlet 57 is installed at the inlet 57 for entering and exiting the laundry provided on the front side of the housing body 52. The door 58 is used for the laundry operation, the dehydration operation, and the dry operation. It is made of a sealed structure so that the washing water in the water tank 60 does not flow out from a gap etc. by locking ().

In the drum type washing machine of the patent application, the water tank 60 is sealed at the time of the washing operation, the dehydration operation, and the drying operation, so the drying heater 69 and the fan disposed above the water tank 60 during the drying operation of the laundry. It is a method of drying the clothes and the like by introducing the heated air generated in the drying unit 68 consisting of 70) into the drum (66). Here, in the drum type washing machine of the patent application, the drying unit 68 consisting of the drying heater 69 and the fan 70 also has a problem that the drum type washing machine becomes expensive because of high cost.

On the other hand, in the drum type washing machine as shown in FIG. 5, the wing body 88 is integrally provided in the rotating shaft part 87 of the drum 86, and the outside air is blown in by the rotation of the wing body 88. JP 2005-261691 discloses a drum type washing machine which sucks into the drum 86 from the wind path 89 and promotes moisture evaporation by bringing the laundry into contact with external air.

However, in the structure disclosed by the said Unexamined-Japanese-Patent No. 2005-261691, there exists a possibility that laundry, such as clothes, may get entangled with the wing body 88 located in the center of a side wall part by rotation of the drum 86. FIG. In addition, since the intake air passage 89 is in the rotary shaft portion 87 of the drum 86, there is a possibility that the washing water flows back outward from the intake air passage 89 depending on the water level in the drum 86 during washing. And, in order to prevent this, it is necessary to employ a waterproof structure that does not overflow, there is a problem that the cost is rather high.

The present invention has been made in view of the above, and it is possible to dry laundry without using a drying unit, and to prevent entanglement of clothing and overflow of water, regardless of the wing structure, and at the same time, It is an object of the present invention to provide a drum type washing machine that can reduce the cost by eliminating the need.

In order to solve the above problems, the drum-type washing machine of the present invention is opposed to the water tank elastically supported in the interior of the housing body to form the outer, the drum rotatably installed around the horizontal axis in the inside of the water tank, the water tank and the front of the drum In the inlet provided in the front of the housing body, and the door is provided rotatably to open and close the inlet, the inlet for sucking the outside air at the upper position than the height of the water level at the time of washing in the water tank is provided, An exhaust port of external air drawn into the drum from the intake port and discharged is formed above the water level.

(Best form for carrying out the invention)

Hereinafter, an embodiment of the present invention will be described based on the drawings. The drum type washing machine 1 shown in a schematic perspective view in FIG. 1 and a side cross-sectional view in FIG. 2 is formed by bending a housing body 2 forming an outline into a horseshoe shape to form a back and both sides. It consists of one outer plate 3, the front plate 4 and the back plate 5 which close the inspection opening of its front surface and back.

And the upper part of the front plate 4 arrange | positions the operation panel 6 for selecting and setting a washing | cleaning course, etc. In the center part, the circular inlet 7 for opening and leaving a laundry is opened, and the said inlet 7 ), A door 8 for closing the inlet 7 by forming a recess in a circular shape, for example, is disposed so that the front surface thereof is almost flush with the front plate 4.

That is, the door 8 forms a circular shape in accordance with the shape of the concave portion of the front plate 4, and also forms the front portion corresponding to the inlet 7 with a transparent body, and the door inner plate (through the peripheral frame) 9) is formed, the door inner plate (9) is a circular window formed of transparent resin or glass excellent in chemical resistance such as detergent or glass so as to see the inside with the transparent portion of the front portion of the circular inlet (7) It expands in the inner direction according to the shape of), and is rotatably supported by one side by the hinge member, and is mounted so that opening and closing is possible in the horizontal direction.

The water tank 10 is arrange | positioned inside the housing body 2. As shown in FIG. As can be understood from FIG. 3, which is a perspective view in which the housing body is omitted, the water tank 10 has a horizontal cylindrical shape to close the rear surface, and an annular water tank cover 10a is attached to an opening peripheral edge of the front portion thereof. And it is elastically supported in the housing body 2 by the pair of support apparatus 11 provided in the left and right of the bottom part of the water tank cover, and it is led out to the outside through the drain valve 12 below the back side. The drain hose 13 is connected.

A water supply port 14 connected to the water supply valve is provided on one side of the main body, and is configured to supply and store tap water as washing water. Moreover, the detergent inlet 15 is provided in the whole main body adjacent to the water supply port 14, and at the time of washing | cleaning, predetermined amount of detergent is supplied to the water tank 10 simultaneously with water supply.

Inside the water tank 10, a cylindrical drum 16 having a base part made of stainless steel that is rotatable around a horizontal axis is provided. The drum 16 is supported in a state slightly inclined upward toward the front along the water tank 10, and includes a plurality of dehydration holes 16a on the main wall of the main body and a baffle for washing clothes on the inner circumferential surface thereof ( A plurality of 16b) is provided. In addition, an annular drum cover 16c is mounted on the front opening side, and is disposed to face the inlet 7 together with the water tank cover 10a to function as a common bath for washing and dewatering operations.

The closed back of the drum 16 is axially supported by the closed back of the water tank 10 and rotated by a motor 17 controlled at a rotational speed following washing and dehydration operations. The motor 17 is, for example, an outer rotor type motor, which fixes the inner stator 17c to the water tank 10 side, and the rotary shaft 17b directly connected to the outer rotor 17a of the water tank 10. The rear wall is watertightly penetrated and connected to the center of the drum 16 and the rear part.

A bellows 18 made of a soft resin material having excellent chemical resistance is mounted in the gap between the peripheral edge portion of the opening 7 of the front plate 4 and the water tank cover 10a of the front opening of the water tank 10. In order to prevent water from leaking out of the water tank 10 to the outside, and extending a part thereof to contact the transparent window 9 on the back side of the door 8 in the closed state, and to the outside from the inlet 7 The leakage of water is also prevented, and a bellows portion is provided to prevent the rotational vibration of the water tank 10 and the drum 16 from being transmitted to the door 8 side.

In addition, in the upper position on the other side of the inlet 7 of the front plate 4 corresponding to the detergent inlet 15, the cross section forms a long hole shape in the width direction and the upper surface is in the outward direction of the water tank 10. A cylindrical inlet 19 is opened, and the lower side is provided in correspondence with the front opening of the drum 16 in the water tank cover 10a, and the filter member 20 is screwed in the opening of the inlet 19. It is attached to and detached freely.

In the ceiling of the housing body 2 corresponding to the inlet port 19, an opening 2a provided with a makeup lattice is formed, and an upper portion of the water tank 10 located behind the inlet port 19 is provided. An exhaust port 21 whose lower side is opened between the drum 16 and the water tank 10 and whose upper side is opened on the upper surface of the water tank 10 is provided.

An exhaust duct 22 formed of an elastic body such as soft rubber is fitted to the upper edge portion of the exhaust port 21, and the exhaust duct 22 is bent backward to penetrate the outer plate 3 and open into the outside air. I'm making it. The opening of the exhaust duct 22 is covered with a semi-cylindrical exhaust cover 23 on the side of the housing body 3 so that the exhaust from the inside is directed upward. The drum 16 and the water tank 10 are provided. Exhaust from the inside of the fan) is led upward of the back of the washing machine 1 to diffuse into the outside air.

The drum type washing machine 1 having the above-described configuration selects and executes the functional processes of "washing", "rinsing" and "dehydration" automatically, and after the laundry is introduced into the drum 16 from the inlet 7, In the "washing" and "rinsing" processes, the drum 16 is rotated at a low speed while the washing water is supplied into the water tank 10, and washing is performed by a stirring motion of lifting and dropping the laundry into the baffle 16b. In the "dewatering" stroke, the drum 16 is dehydrated by rotating at high speed in one direction.

Therefore, in the "dehydration" process, the water of the laundry after washing is removed by centrifugal force from a plurality of dehydration holes 16a provided in the circumferential wall of the main body of the drum 16 to perform dehydration. Since the air inside is discharged from the dehydration hole 16a and the drum 16 becomes negative pressure, the opening 2a formed in the ceiling surface of the corresponding housing body 2 is formed in the intake hole 19 on the upper portion of the water tank 10. A large amount of dried outside air is sucked in through) and is introduced into the front opening of the drum 16 from the rear of the inlet 7. At this time, since the filter member 20 is provided in the intake port 19, it is possible to prevent dust, insects, etc. in the outside air from entering the drum 16 and adhering to the laundry.

Then, the laundry is contacted with the laundry inside the drum 16, and the moisture is taken out and discharged outward from the dehydration hole 16a as air containing moisture, and the laundry is forced to dehumidify by the air sucked with dehydration by centrifugal force. Can greatly promote the drying action.

The air discharged from the dehydration hole (16a) is led between the outer surface of the drum 16 and the inner surface of the water tank 10 is led to the exhaust port 21 opened in the upper surface of the water tank 10, which is a closed space, It passes through the exhaust duct 22 and is discharged to the outside.

At this time, the exhaust gas is preferably discharged into the outside air. Because if discharged into the housing body 2, the exhaust gas may be filled inside the housing body 2, and in such a case, the exhaust capacity will be reduced, which will not only disturb the intake of new dry air, but also air containing moisture. There is a possibility of causing the castle to adhere to the inner wall of the wall, but by being released into the outside air, it does not stay with the dissipation of the humidified air, so that a sufficient intake amount can be ensured.

Since the exhaust port 21 of the above embodiment opens the rear surface further away from the intake port 19 on the upper surface of the water tank 10, the intake air entering from the front of the drum 10 is in long contact with the laundry in the water tank before and after. After that, it is allowed to flow out of the rear exhaust port 21 so as to further dry the laundry. The air flowing out of the exhaust duct 22 is further led upward by the exhaust cover 23 from the upper rear surface of the outer plate 3 and diffused into the outside air, so that the air stays between the washing machine 1 and the seal wall surface to form frost. The occurrence of mold and the like can be suppressed without generating adhesion phenomenon.

Since the inlet port 19 and the exhaust port 21 are respectively disposed in the upper portion of the water tank 10, it is possible to prevent the overflow of water to the outside of the water tank without being affected by the agitated water level in the washing process of "washing" or "rinsing". Can be. In addition, the part which installs the said intake port 19 and the exhaust port 21 should just be a position higher than the water level at the time of washing | cleaning, and it does not need to be the upper part of the water tank 10. FIG.

According to the above configuration, the laundry in the drum 16 is subjected to a dehydration action by centrifugal force due to rotation with the drum 16 by the "dehydration" process after washing, and a conventional heater and a fan by the dehumidification action by the suctioned outside air. It can be made almost dry without using the drying unit 68 which consists of these, and a drying effect can be acquired at low cost.

In addition, in the drum type washing machine structure in the present state, the inlet port 19 and the exhaust port 21 can be integrally formed with the water tank cover 10a or the water tank 10, and the exhaust port 21 and the exhaust duct ( 22 and the exhaust cover 23 can be installed in the rear inclined spaces of the drum 16 and the water tank 10 which are normally inclined downward toward the rear, and thus do not need to provide a new installation space. The contours do not have to be enlarged or altered, which allows for effective drying without the need for major specification changes.

Moreover, the gap with other components may be utilized as an exhaust port in the upper part of the water tank 10, without providing the member of the exhaust port 21 as a molded object, and the said drain valve 12 connected to the lower part of the water tank 10 further. May be opened and exhausted from the drain hose 13.

In addition, by setting the opening area of the part of the exhaust port 21 at least larger than the opening area of the inlet port 19, the outside air sucked into the drum 16 does not stay, and a sufficient suction amount of the outside air can be ensured. It is possible to form a smooth suction, circulation and exhaust process.

In addition, while the above-mentioned "washing" and "dehydration" operation, the water droplets by stirring or dehydration are generated, but the water tank 10 is provided in a watertight manner with respect to the main body outer surface 3, and also the opening of the inlet 7 As the bellows 18 mounted at the edge portion is elastically in contact with the glass window 9a swelling toward the rear side of the door 8, water droplets are reliably sealed so that the bellows 18 is not only outside the washing machine 1 but also outside the water tank 10. Water does not leak

According to the drum type washing machine of the present invention, it is possible to effectively remove moisture from the laundry, and it is possible to obtain an inexpensive drying configuration without adopting a complicated configuration for damaging the laundry by entanglement or preventing the overflow of water.
