The rear cover 18 includes an intake unit 182 formed to allow external air to flow therein, and an exhaust hole 184 that is a passage through which the air of the drum 20 is discharged to the outside.

Inside the drum 20, it is preferable that the lifter 22 is installed to invert the object and increase the drying efficiency of the object.

On the other hand, the front supporter 30 and the rear supporter 40 are provided between the drum 20 and the cabinet 10 (front cover 16 and rear cover 18).

A drum 20 is rotatably installed between the front supporter 30 and the rear supporter 40, and a sealing member for preventing leakage between the front supporter 30 and the rear supporter 40 and the drum 20, respectively. (Not shown) is installed.

That is, the front supporter 30 and the rear supporter 40 form a drying chamber by blocking the front and rear surfaces of the drum 20 and serve to support the front and rear ends of the drum 20.

The front supporter 30 is formed with an opening for communicating the drum 20 with the outside of the dryer, the opening is selectively opened and closed by the door. In addition, the front supporter 30 is connected to the lint duct 50 which is a passage through which the air of the drum 20 is discharged to the outside, and the lint duct 50 is provided with a lint filter 52.

The lint duct 50 is provided with a lint filter 52. In this case, one side of the blower unit 60 is connected to the lint duct 50, the other side of the blower unit 60 is connected to the exhaust duct 80, and the exhaust duct 80 is connected to the rear cover 18. In communication with the exhaust hole 184 is provided.

Therefore, when the blower unit 60 is operated, the air in the drum 20 is discharged to the outside through the lint duct 50, the exhaust duct 80, and the exhaust hole 184.

At this time, foreign matter such as lint is filtered in the lint filter 52. Typically, the blower unit 60 is composed of a blower 62 and a blower housing 64, and the blower is generally connected to and driven by a motor for driving the drum 20.

The rear supporter 40 is formed with an opening, which is usually composed of a plurality of through holes, and a hot air supply duct 44 is connected to the opening. The hot air supply duct 44 communicates with the drum 20 to serve as a passage for supplying hot air to the drum 20. Therefore, the hot air heater 240 is installed at a predetermined position of the hot air supply duct 44.

Meanwhile, a steam generator 200 for generating steam and supplying the steam to the inside of the drum 20 is installed at a predetermined position of the cabinet 10.

The steam generator 200 will be described with reference to FIG. 3 as follows.

The steam generator 200 includes a water tank 210 in which water is accommodated therein, a heater 240 mounted in the water tank 210, and a water level sensor for measuring the water level in the water tank 210. 260, and a temperature sensor 270 for measuring the temperature of the water contained in the water tank (210).

The water level sensor 260 is generally composed of a common electrode 262, a low level electrode 264, and a high level electrode 264, so that the common electrode 262 and the high level electrode 264 are energized or the common electrode 262 and the low level electrode ( 266) detects the high and low water levels according to whether or not the power is supplied.

One side of the steam generator 200 is connected to the water supply passage 210 for supplying water, and the other side is connected to the steam hose 230 for discharging steam.

The tip of the steam hose 230 is preferably a nozzle 250 is installed to increase the injection efficiency of steam.

In general, the water supply passage 210 of the steam generator 200 is connected to an external water supply source such as a faucet installed outside the dryer, and the water is supplied to the water tank 210 while the water supply amount is controlled by a separately configured controller.

This method is an efficient method for a device that requires a large amount of water, such as a washing machine, and may be inefficient when predetermined water is required to be used only for generating steam in the steam generator 200 such as a dryer.

That is, when an auxiliary device such as a water supply hose or a control unit is installed in the dryer requiring only a predetermined amount of water, the installation cost of the auxiliary device increases, and thus may be inefficient as a water supply source for supplying water to the dryer.

Therefore, in the present invention, as shown in Figure 4, it is proposed that the water supply source for supplying water to the steam generator 200 is configured to be removable.

As can be seen through Figure 4, the steam generator 200 is provided with a water container 300 that is a removable water supply source, and a water supply passage 210 for supplying water from the water container 300 to the steam generator 200 is installed. do.

The water container 300 is provided with a space for accommodating predetermined water, and at one side, an outlet 310 through which water flows into the water supply passage 210 is formed. In this case, the outlet 310 is detachably connected to the water supply passage 210.

In addition, the water container 300 is preferably mounted in the drawer type drawer 320 to be pulled in and out from the front of the front cover 16 of the dryer.

At this time, the guide unit 330 for guiding the drawer 320 toward the water supply passage 210 is installed inside the dryer.

In addition, the water supply passage 210 is installed between the water container 300 and the steam generator 200 as a flow path for supplying the water flowing out of the water container 300 to the steam generator 200.

At this time, it is preferable that the pump 400 is installed on the water supply passage 210 so as to smoothly supply the water of the water container 300 to the steam generator 200.

Of course, in the process of supplying water from the water container 300 to the steam generator 200, it is also possible to supply water by water parking, but various parts of the dryer are standard products and are designed compactly, so that the space is narrow in structure. It is true. Accordingly, since the water supply using the water parking is virtually impossible without changing the size of the parts, it is preferable to install a small pump 400 on the water supply passage 210 so that water can be smoothly supplied.

If the pump 400 is installed, not only can smoothly supply water from the water container 300 to the steam generator 200, but also can easily recover the water in the water tank 210 from the steam generator 200. There is an advantage.

The reason for recovering the water in the water tank 210 is that when the steam generator 200 is not used for a long time, the heater 240 may be damaged by the remaining water, or the decayed water may be used later.

At this time, the water supply passage 210 is connected to the outlet 211 of the guide portion 330 to correspond to the outlet 310 of the water container 300, and the water supply pipe 213 connected between the pump 400 and the steam generator 200 And a connecting pipe 212 connected between the pump 400 and the connection port 211.

5A and 5B, the connection relationship between the water container and the connector will be described in detail.

The outlet 310 of the water container 300 is provided with a pin 365 for selectively opening and closing the flow path of the outlet 310.

The flow path 311 includes an inner flow path 311a and an outer flow path 311b, and an O-ring 369 is provided on an outer surface of the outer flow path 311b.

Meanwhile, a recess 366 is formed at one side of the trunk portion 365b of the pin 365, and a flow portion 365a is formed at the other side.

The opening and closing portion 367 is installed in the recess 366, and the flow portion 365a is formed in a substantially cross shape so that water in the water container 300 flows between the cross blades.

In addition, the inside of the flow path is provided with a support portion 363 supporting the body portion 365b of the pin 365 and having a plurality of through holes 363a, and the support portion 363 and the flow portion of the pin 365 ( The spring 364 is provided between the 365a.

The connection port 211 includes an outer portion 211a having an inner diameter larger than an outer diameter of the outer passage 362b of the opening and closing member 360, and an inner portion 211b having an outer diameter smaller than the inner diameter of the outer passage 362b. do.

As shown in FIG. 5A, when the drawer 320 is pushed into the dryer to supply water to the steam generator 200, the drawer 320 is along the guide unit 330. The outlet 310 of the water container 300 is inserted into the connection port 211 installed in the guide part 330.

That is, the pin 365 in the outlet 310 is advanced by the inner portion 484 of the connection port 211 to overcome the elastic force of the spring 364 to the inner flow path 311a. Accordingly, the opening and closing portion 367 provided at one side of the pin 365 is separated at the tip of the inner flow path 311a and water flows through the gap, so that the water in the water container 300 flows in the pump 400 direction through the flow path. Will be.

On the other hand, when the drawer 320 is pulled to supply water to the water container 300 or discard the water recovered from the steam generator 200, one side of the pin 365 by the restoring force of the spring 364 The opening-closing portion 367 provided in the upper portion is in a state of blocking the tip of the inner flow path 311a.

However, residual water remains in the outer flow path 311b and the connection port 211 of the outlet 310. Therefore, the remaining water from the outer flow path 311b and the connection port 211 may fall into the dryer.

If the residual water falls as described above, the rust is generated while the water in the parts in the dryer can be shortened the life of the parts.

Accordingly, even if the residual water flows out from the outlet 310 and the connection port 211 of the water container 300, it is required to prevent the residual water from falling on the component.

6A and 6B, a dryer provided with a water storage part 500 for preventing the remaining water from the water container 300 and / or the connection port 211 from touching the parts will be described.

6A and 6B are cross-sectional views schematically illustrating a state in which the water storage part 500 is installed below the water container 300 and the water supply passage 210.

When the water container 300 is removed from the connector 211 to be withdrawn to the outside of the dryer, the reservoir 500 does not drop the residual water flowing out of the connector 211 and / or the water container 300 to the parts in the dryer. It serves as a drip tray so as to pick up the remaining water.

To this end, the reservoir 500 is installed at the lower side of the water container 300 and the water supply passage 210, it is preferably made of a tray form having a storage space for storing water.

In addition, the tray is more preferably installed in the form of a drawer to be easily drawn in and withdrawn from the front of the dryer.

At this time, the front portion of the tray exposed to the front of the dryer is preferably formed with a handle so that the user can easily enter and withdraw.

On the other hand, it is preferable that the remaining water receiving portion is further installed between the tray and the water supply passage.

This is to prevent the residual water flowing out of the outlet 310 and the connection port 211 of the water container 300 directly falling on the tray, when the residual water falls directly on the tray and the connection port 211 and the outlet 310 and This is because residual water may splash out of the tray 500 due to the height difference of the bottom surface of the tray.

At this time, the tray 500 may be installed in close proximity to the connection port 211 and the outlet 310 without installing the remaining water container 600, but the drawer in the process of the tray 500 is drawn in and drawn out ( 320 or the guide unit 330 may be interfered with.

Therefore, a sufficient space is secured between the tray 500, the outlet 310, and the connection port 211 so that the tray 500 can be smoothly drawn in and taken out from the dryer. By installing the to compensate for the height difference between the tray 500, the connection port 211, the outlet 310.

The residual water receiving portion 600 is formed in a concave container shape, it is natural that the drainage hole 610 is formed on the bottom surface so that the stored water can immediately exit to the tray 500.

In addition, the bottom surface is more preferably formed to be inclined toward the drain hole 610 from the edge of the bottom surface.

This is to allow the residual water accumulated on the bottom surface to flow smoothly toward the drainage hole 610.

By the above configuration, even if the water container 300 is removed from the connection port 211 to draw out the water container 300 to the outside of the dryer, as shown in FIG. 6B, the remaining water is the remaining water container 510. It is stored in the tray 500 through).

Then, after a certain period of time, the user withdraws the tray 500 from the dryer and discards it to the outside of the dryer.

Therefore, when the water container 300 is removed from the connection port 211, the residual water that flows out does not fall into the parts of the dryer, but collects in the reservoir.

According to the dryer according to the present invention, since the steam generator is provided in the dryer, wrinkles are not generated in the laundry even after the laundry is dried by the dryer, and the sterilization and the smell of the dry matter are removed.

In addition, the water supply source for supplying the water to the steam generator is mounted on the dryer, it is detachably installed so that the installation cost of the auxiliary devices for supplying water to the steam generator is not necessary, thereby reducing the manufacturing cost.

In addition, the water container for supplying water to the steam generator and the water reservoir is installed on the lower side of the water supply flow path so that the residual water flowing out of the water supply flow path and / or the water container at the time of removal of the water container from the water supply flow passage does not fall to the water storage part. Stored.

As a result, the water does not come into contact with the parts, so that the life of the parts due to rust is not shortened.
