Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for combined use of dehydration, which has an improved structure for supporting and fixing a drain hose in the machine.

[0002]

2. Description of the Related Art Conventionally, in a washing machine for combined use of dehydration,
A midway portion of the drain hose that drains water from the tank for washing and dehydration to the outside of the machine was supported and fixed to the outer box.

[0003]

However, the tub of the washing machine for combined use of dehydration is elastically supported by a plurality of hanging bars, springs, etc. so as not to transmit the vibration due to the large shaking at the time of dehydration to the outer box. Therefore, the drain hose is also shaken with the shaking.

On the other hand, the outer box supporting and fixing the midway portion of the drain hose is generally made of a steel plate and is made of hard metal, and is rocked by the hard metal outer box as described above. Since the part of the drainage hose that contacts the inside of the machine is rubbed, it is expected that the drainage hose normally made of a soft material such as vinyl chloride will be broken.

For this reason, the drainage hose of the washing machine for combined use of dehydration is formed only by blow molding on the outside of the machine, while another inside of the machine is reinforced with a wire. ..

[0006] However, in such a structure, there is a problem that the cost becomes high and the manufacturability is poor due to the trouble of connecting the inside and the outside of the drain hose one by one.

The present invention has been made in view of the above-mentioned circumstances, and therefore an object thereof is an excellent dewatering and washing for drainage hose and its supporting and fixing in a machine, which can reduce cost and improve manufacturability. To provide the machine.

[0008]

In order to achieve the above object, in a washing machine for combined use of dehydration according to the present invention, an outer box for accommodating a main body for elastically supporting washing and dehydration in the same tank is made of plastic. In a combination of the base plates of, the base plate is separated from the outer box to form a hose support,
The drainage hose for draining water from the tank to the outside of the machine is supported by the hose support portion at an intermediate part in the machine.

Further, in this case, the hose supporting portion is characterized in that the midway portion of the drainage hose is fixed in the machine by a fixing band which is pulled from the work opening of the outer box toward the work opening and stopped. ..

[0010]

According to the above means, the middle portion of the drainage hose inside the machine is separated from the outer box and comes into contact with the hose support (base plate). The hose support (base plate) is made of plastic. Therefore, even if it is rubbed, the conventional hard metal outer box will not be liable to break. Therefore, as the drainage hose as a whole, it is possible to use only the blow-molded one, and it is possible to eliminate the need to use another reinforced inside the machine.

Further, with respect to the fixing of the above-mentioned midway portion of the drainage hose, the work can be finished smoothly from the work opening of the outer box.
