Description

Drying drum washing machine {drum-type washing machine with dryer}

The present invention relates to a dry drum washing machine, and more particularly, to a dry drum washing machine which improves the condensation efficiency by improving the structure of the condensation duct to remove moisture from the air sucked into the condensation duct.

In general, the drum washing machine is a device for washing laundry by rotating the drum by the driving force of the motor in a state in which detergent, washing water and laundry are put into the drum. The drum washing machine is less damage to the laundry and the laundry is not tangled well, knocking and rubbing has the advantage of producing a laundry effect.

Hereinafter, with reference to the accompanying Figure 1 with respect to the drum washing machine according to the prior art as follows.

1 is a side cross-sectional view schematically showing a drum washing machine according to the prior art.

As shown in FIG. 1, the drum washing machine according to the related art includes a cabinet 10 having a laundry inlet formed on a front surface thereof, a door 20 installed to be opened and closed at a laundry inlet of the cabinet 10, and the cabinet ( 10) a metal tub 30 installed to store wash water therein, a drum 40 rotatably installed in the tub 30, and the drum 30 installed in the tub 30. It is configured to include a motor device 50 for transmitting a driving force to.

Here, the door glass 21 is installed in the door 20 to protrude toward the opening side of the tub 30.

In addition, a hanging spring 90 for supporting the tub 30 is installed between the inside of the upper surface of the cabinet 10 and the upper side of the outer circumference of the tub 30, and although not shown, a lower surface of the cabinet 10. A friction damper is provided between the inner side and the lower side of the outer circumferential surface of the tub 30 to damp the vibration of the tub 30 generated when the drum washing machine is operated.

In addition, the motor device 50 is an indirect driving method for transmitting the driving force generated from the motor 51 to the washing shaft 53 by the belt 52 to rotate the drum 40.

On the other hand, a drying duct 60 is installed on the upper inner surface of the cabinet 10. In this case, a blowing fan 62 and a heater 61 are built in the drying duct 60 to discharge hot air. One end of the drying duct 60 is installed in communication with the door 20 side opening of the tub 30.

Here, one end of the drying duct 60 and the opening of the tub 30 are connected by a gasket 80. The gasket 80 is installed along the front inner edge of the tub 30 and has a corrugated shape to accommodate the vibration of the tub 30. Accordingly, hot air is prevented from leaking through the connection portion between the drying duct 60 and the tub 30.

In addition, the tub 30 is provided with a condensation duct 70 so as to communicate with the drying duct (60). At this time, one end of the condensation duct 70 is connected to the outer surface of the tub 30, the other end of the condensation duct 70 is connected to the drying duct (60). The condensation duct 70 is provided with a water supply 71 for supplying cooling water to condense moisture in the air to remove moisture.

The drum washing machine configured as described above performs washing, rinsing, dehydrating and drying operations. Hereinafter, the drying operation of the drum washing machine will be described.

When the drying operation of the drum washing machine is started, power is applied to the heater 61 of the drying duct 60. At this time, as the blowing fan 62 and the heater 61 are operated, the blowing fan 62 blows hot air.

The hot air is introduced into the drum 40 by hitting the inclined portion of the door glass 21 by the guide of the drying duct 60.

Then, the hot air introduced into the drum 40 heats the laundry to evaporate the moisture contained in the laundry. At this time, by stirring the laundry while the drum 40 is rotated at a low speed, the laundry is evenly exposed to hot air to help evaporation of moisture.

The evaporated water is discharged through the condensation duct 70 in a state of being contained in the air. At this time, by spraying water from the water supply 71 of the condensation duct 70, moisture in the air is removed. The air from which moisture is removed is introduced into the drying duct 60 again, and the air introduced into the drying duct 60 is converted into hot air by the heater 61 and the blower fan 62 and reintroduced into the drum 40. Drying is performed on the laundry.

The laundry is dried while repeatedly performing this series of procedures.

However, in the conventional drum washing machine, the drying duct 60 is connected to one side of the upper gasket 80 and supplied into the drum 40 through this portion, and the supplied drying air is again provided at the front side of the tub 30. It has a structure that is discharged through the circulation and had problems in various aspects such as drying efficiency.

First, the air supplied into the drum 40 is discharged through the front side of the tub 30 in a state in which the air supplied to the drum 40 does not penetrate deeply inside the drum 40, and thus, drying is not performed properly in the deep space inside the drum 40.

Therefore, the existing flow path structure has a disadvantage in reducing the drying efficiency and drying performance.

Second, the conventional drying drum washing machine is a drying duct 60 is connected to the gasket 80, the drying duct 60 is fixed, the gasket 80 is due to the flow during the vibration of the tub 30 Wear and tear of the gasket 80 had a disadvantage that occurs.

Therefore, since an expensive gasket having a relatively small thermal deformation must be installed, there is a problem in that the manufacturing cost is increased.

Third, the drying duct 60 is discharged vertically downward through the gasket 80, which is displaced from the axial direction of the drum 40, and the hot air discharged is hit by the door glass 20 and subjected to resistance. There is a problem that the hot air is not introduced deep into the drum (40).

Therefore, to overcome this, a blower having a larger capacity must be installed.

Fourth, since the hot air of the drying duct 60 is switched from the inclined portion of the door glass 21 via the gasket 80 to flow into the drum 40, the door 20 and the tub ( There is a disadvantage in that 30) is unnecessarily heated.

Fifth, since the cooling water supplied to the water supply 71 flows dispersed in the condensation duct 70, there is a problem that the condensation efficiency is lowered.

The present invention has been made in order to solve the above problems, the present invention relates to a dry double drum washing machine employing a new flow path structure that improves the drying efficiency and drying performance compared to the conventional dry double drum washing machine, The aim is to provide a structure of condensation ducts that is particularly suitable for modified systems.

In order to achieve the above object, the present invention is installed in the cabinet to store the wash water, a tub having a hot air inlet formed in the upper portion of the front, rotatably installed in the inside of the tub, a hot air inlet formed in the front and And fixedly installed to be in close contact with an outer circumferential surface of the upper side of the tub, and a heater and a blowing fan are built therein to generate hot air, and one end thereof is connected to a hot air inlet of the tub to generate hot air generated therein. And a drying duct supplied to the rear end of the tub so that one end is connected to the rear surface of the tub and the other end is connected to the drying duct, thereby removing moisture contained in the air discharged from the tub. It includes a condensation duct leading to the duct.

At this time, one side surface of the condensation duct is provided with a combined drum washing machine characterized in that the cooling water guide groove is formed to prevent the cooling water is dispersed to flow to the lower side well.

Next, the hot air introduced into the drum 40 heats the laundry to evaporate the moisture contained in the laundry, and the evaporated water is discharged to the hot air outlet 32 of the tub 30 in a state of being included in the hot air. The suction of the wet air into the condensation duct 100 is performed.

Next, the wet air sucked into the wet air inlet 101 flows to the wet air inlet 102.

Subsequently, the water supply 71 supplies cooling water into the condensation duct 100, and the supplied cooling water flows along the cooling water guide groove 110 to the side where the water splashing protrusion 120 is provided.

At this time, the scattering action occurs due to the collision of the cooling water flowing along the cooling water guide groove 110 and the water splashing projection (120).

At this time, it is fused with the humid air passing through the humid air inlet 102 side and the cooling water scattered, the condensation is actively performed.

That is, due to the cooling water guide groove 110 and the water splashing projection 120, the contact area between the wet air and the cooling water is widened, condensation efficiency is increased.

Next, the condensed moisture is discharged to the lower side of the tub 30 connected to the condensation duct 100 together with the cooling water.
