A condensation conduit 50 is connected to the tank 20 to extract the air from the tank 20 and the drum 30. Specifically, the condensation conduit 50, shown in fig. 1 and in fig. 2, is connected to the lower back of the tank 20 to condense the air introduced into it using water of refrigeration. To this end, a supply pipe 51 of water, shown in fig. 1, is connected to conduit 50 of condensation to supply the cooling water to the duct 50 condensation

Water supply pipe 51 is connected to the upper part of the condensation duct 50. He cooling water supplied to the condensation line 50 from the water supply pipe 51 flows down to the length of the inner circumference of the condensation duct 50 to be collected in the lower part of the tank 20. Therefore, the moisture contained in the warm and humid air introduced into the condensation conduit 50 is condensed by the water of cold cooling flowing along the circumference inside the condensation duct 50, so that the air that flows in the condensation conduit 50 becomes drier. By On the other hand, it is not necessary to provide another seal in the connection part between the condensation conduit 50 and the tank 20 to absorb vibration and prevent leakage.

A drying line 40 is connected to the condensing duct 50 and to the tank 20 for supplying air hot and dry inside the tank 20. Specifically, inside of the drying duct 40 a fan 42 is provided which sucks the air from the tank 20 and the drum 30 through the duct 50 condensation and that supplies the air sucked into the tank 20 through the drying line 50, and a heater 41 which heats the dry air supplied to the tank 20 through the drying duct 40. Therefore, the dry air that was sucked in inside the drying duct 50 to remove its moisture is heats as it passes through the drying line 40 and then returns to the tank 20.

Both ends of the drying line 40 are connected to an upper end of the condensation conduit 50 and to a front part of the tank 20, respectively. Specifically, one end of the drying conduit 40, shown in fig. 1 and in fig. 2, is connected to the top of the cuba 20. For this, an air inlet 20a, which is connected to the drying duct 40 and introducing the hot air supplied from the drying conduit 40 to the interior of the tank 20, it is provided in the upper front part of tank 20. An element Sealing (not shown in the drawings) may be provided in a connecting part between the drying line 40 and the tank 20 for Prevent heat from escaping from drying line 40. The air hot introduced inside the tank 20 through the entrance 20a of air can be supplied to the drum 30 through the openings 39 provided in the circumference of the drum 30.

In order to supply the hot air to the drum 30 more effectively, a plurality of holes 30a of air is provided at the front of the drum 30 to introduce the hot air into the drum 30. The plurality of air holes 30a, shown in fig. 1 and in fig. 2, is provided on the front of the drum 30 facing the part front of the tank 20 and, more particularly, is intended for stand in front of the air inlet 20a during the rotation of the drum 30.

For this, the air holes 30a, shown in fig. 3 and in fig. 4, are provided in the front of drum 30 in a circumferential direction. In other words, the opening 31 is formed in the center of the front part of the drum 30 and the plurality of air holes 30a is arranged in the front part of the drum 30 to surround the opening 31 of the same. Specifically, each column of air holes 30a, shown in fig. 3, form a straight line in one direction radial of the drum 30. Alternatively, each column of the air holes 30a, shown in fig. 4, is inclined in against the radial direction of the drum 30. In addition, the plurality of air holes 30a may be arranged in the front of the drum 30 randomly.

If the plurality of air holes 30a is provided along the circumference of the front of the drum 30, the hot air introduced into the tank 20 a through the air inlet 20a of the tank 20 can be introduced effectively inside the drum 30 through the holes 30a of air of the drum 30 in spite of the rotation of the drum 30.

On the other hand, the air holes 30a provided on the front of the drum 30 are formed, by example, by drilling. Specifically, during the manufacture of the drum 30, the front part of the drum 30 is punch from the inside out. Therefore, if the holes 30a of air are formed in the manner described above, they will be generated a burr 30c in the vicinity of each of the holes 30a of air, as shown in fig. 5 and in fig. 6, oriented out. Therefore it is effectively prevented that clothing inside the drum 30 is damaged by burrs 30c.

However, when drying clothes, there is fluff in the hot air introduced into the tank 20 through the drying duct 40 and air inlet 20a. Therefore, the lint present in hot air can get caught in the burrs 30c in the vicinity of the air holes 30a when the Hot air passes through the air holes 30a. Further, it is highly likely that each of the air holes 30a Get stuck with a handful of fluff. Preferably, it is it is necessary to remove the burr 30c despite being located in the outside of the drum 30. For this, during the manufacture of the drum 30, the burr 30c formed in the vicinity of each of the air holes 30a is cut from the outside of drum 30 to provide a smooth surface thereof.

On the other hand, if the plurality of holes 30a of air is provided at the front of the drum 30, the drum stiffness 30 may decrease. To prevent a minor rigidity of the drum 30, an embossing process is carried out on the front of the drum 30. Specifically, after it formed the air hole 30a during the manufacture of the drum 30, an outer edge of the air hole 30a, shown in fig. 6, emboss out to form an embossed part 30b that protrudes outward from the front of drum 30. As As a result, the corresponding air hole 30a is provided in the center of the tip of the corresponding embossed part 30b and the corresponding burr 30c is formed around the tip corresponding of the corresponding embossed part 30b. For the both, trimming the tip of the embossing after completion of embossing processing, burr 30c, shown in fig. 6, It can be removed in a clean way.

On the other hand, the drying line 40 is stably fixed on top of tank 20 by a coupling element such as a screw or a cap screw. A prescribed space is provided between the top of the tank 20 and the lower part of the drying duct 40, and a insulator 43 is provided in the prescribed space to prevent The heat of the drying line 40 is transferred to the tank 20.

       \ newpage
    

The insulator 43, shown in fig. 1 and in the fig. 2, is coupled to the top of the tank 20 to look at it and have sufficient size and thickness as to effectively prevent heat from conduit 40 from drying is transferred to tub 20. In addition, the central part of the drying duct 40 can be installed to be supported by the insulator 43. Since the insulator 43 supporting the conduit 40 drying can absorb the vibration of the drying conduit 40, not another element that absorbs vibration is necessary.

On the other hand, a plurality of ribs 23 of reinforcement to improve the rigidity of the tank 20 is provided in the proximity of the air inlet 20a of the tank 20 to prevent that the proximity of the air inlet 20a of the tank 20 undergo a transformation because of the influence of air hot blow from the blow duct 40. To do this, the air inlet 20a of the tank 20 has an almost rectangular and each of the reinforcement ribs 23 protrudes from inside the tank 20 to present a length default in a direction perpendicular to one side corresponding of the 20a rectangular air inlet. How alternatively, the reinforcement ribs 23 may be provided in outside of Cuba 20 unless they interfere with the coupling with the drying line 40. In addition, the plurality of reinforcement ribs 23 may be provided inside or in the exterior of the tank 20 along an edge of the entrance 20a of air.

Next, a washing machine will be explained and dryer according to another embodiment of the present invention shown in fig. 8 and in fig. 9. The configuration of the washing machine and dryer according to another embodiment of the present invention is basically identical to that of the first embodiment of the present invention. However, this second embodiment of the present invention differs from the first embodiment of the present invention in which an air guide 25 is provided in the tank 20 to guide the hot air blown from the drying line 40 into the drum 30.

The air guide 25 extends from the entire edge of the air inlet 20a towards the interior of the tank 20. The air guide 25 is formed, for example, as a unitary body with an edge of the air inlet 20a. As an alternative, the guide 25 of air can be formed as an independent body of the tank 20 and can then be attached to the interior of the tank 20. The guide 25 of air may be tilted down towards drum 30. In addition, even if the drawing shows that an air guide 25 inlet connected to the air inlet 20a has a sectional area transverse, that is, a passage area, approximately similar to that of an outlet of the air guide 25 in the vicinity of the drum 30, the cross-sectional area of the air guide 25 can gradually increase or decrease towards the exit of guide 25 of air.

The reinforcement ribs 23 may protrude from the outer circumference of the air guide 25 and from the front part of the tank 20 to reinforce the rigidity of the proximity of the air guide 25 and the front part of the tank 20. Specifically, reinforcement ribs 23 and guide 25 of Air can be provided as a unit body. In this case, the air guide 25 and the reinforcement ribs 23 can be formed by injection molding with cuba 20 as a unit body in itself. Alternatively, the air guide 25 can be formed separately from a steel or resin based material synthetic unlike cuba 20 to be assembled within the air inlet 20a.

As mentioned in the description above, by means of the air guide 25 provided inside the air inlet 20a of the tank 20, the air introduced into the air inlet 20a through the drying duct 40 can Gently enter the drum 30 through the air holes 30a of the drum 30 without spreading in front of the drum 30, so that the efficiency of the dried

In First, once a drying cycle has started, it activate heater 41 and fan 42 inside duct 40 drying The hot air generated from heater 41 and the fan 42 inside the drying duct 40 is inserted inside of the drum 30 through the air inlet 20a of the tank 20 and of the air holes 30a of the drum 30. By doing this, the air hot is introduced inside the inner top of the drum 30 in an axial direction of the drum 30. Therefore, the air hot is supplied to the rear of the drum 30 drying in that way the clothes contained in the drum 30 effectively. When the hot air is supplied to the tank 20 through the air inlet 20a, reinforcement ribs 23 provided in the proximity of the air inlet 20a of the tank 20 prevents the proximity of the air inlet 20a of the tank 20 experience A transformation because of the heat.

The warm and humid air that has dried clothes inside the drum 30 is discharged out of the tank 20 through the 50 condensation duct. By doing this, the duct 50 of condensation sucks the air from the inner bottom of the drum 30 along the axial direction of the drum 30, for example. Next, the air from the inside front bottom of the drum 30 is sucked into the condensation duct 50, by what the clothes contained inside the drum 30 can dry out of effective way.

As mentioned in the description above, the drying duct 40 supplies the hot air towards the upper space of the drum 30 along the direction axial of the drum 30 and the condensation duct 50 sucks the air of the lower space of the drum 30 along the axial direction of the drum 30. With the air flow another air flow is generated in the drum 30 in a diagonal direction. Specifically, a part of the air that has been supplied to the drum 30 through the part upper front of drum 30 crosses a diagonal path which is the shortest path through drum 30 through of the lower rear part of the drum 30. In this case, if the guide 25 air is provided in a downwardly inclined manner, the Air flow through the diagonal path increases. For the therefore, hot air circulates smoothly throughout all parts of the inside of drum 30 to dry clothes evenly.

On the other hand, drum 30 keeps spinning by motor 60. The clothes inside the drum 30 are lifted by  the elevators 35 to fall again, thus exposing themselves of uniform way to hot air supplied to drum 30. So Therefore, drying efficiency is improved.

The warm and humid air that has dried clothes inside the drum 30 is then introduced into the duct 50 of condensation. The humidity of the hot and humid air condenses due to the cooling water supplied to the duct 50 of condensation through the water supply line 51. He dry moisture free air flows through fan 42 and the heater 41 to transform into hot air and hot air is supplied back to tank 20.

For experts in the field it will be evident that several modifications and variations can be made in the present invention For example, the drying duct may be connected to the rear of the drum and the conduit of Condensation may be connected to the front of the tank. Therefore, the present invention is intended to cover variations and the modifications of this invention provided they are within the scope of the appended claims and their equivalents.

Industrial applicability

As explained in the previous description of the present invention, hot air is introduced inside the drum through the front of the drum and the air inside the drum is drawn through the back of the drum. In addition, hot air is conducted gently towards the drum using the air guide in the vicinity of the inlet of hot air. Therefore, air can be supplied to any site inside the drum, thereby drying clothes effective.

In addition, the drying line is connected directly to the tank, while the drying duct of the Related technique is connected to the gasket. So, it is previously prevented that the sealing gasket suffer any hurt.

In addition, hot air is supplied directly towards the drum without the guidance of the inclined part of the door. In addition, the insulator prevents heat from the duct from Drying is transferred to the tub. Therefore, the present invention prevents the door and the tank from heating unnecessarily, thereby reducing energy consumption and improving drying performance.

In addition, the drum of the present invention is equipped with air holes in its front part to introduce the hot air in it. In addition, the air holes are formed by drilling, embossing and deburring. Therefore, the The present invention effectively prevents the decrease of rigidity of the drum, damage to clothes and jams in the holes of air.

On the other hand, reinforcement ribs in the proximity of the air inlet can prevent the tank undergo a transformation because of hot air heat introduced through the air inlet.

And also, since the drying duct and the Condensation conduit are fixed to the tank, it is not necessary install another gasket on the connection part between the tank and the condensation conduit or the drying conduit.

Finally, since the drying duct is fixed to the top of the tank to act as a counterweight, the present invention facilitates the balance of the Cuba.
