The present invention relates to a steam dryer, and more particularly, to a steam dryer that can remove or prevent wrinkles, wrinkles, etc. generated in clothing and the like.

A dryer is a household appliance in which laundry is normally washed, that is, clothes are mainly dried using high temperature air. In general, the dryer includes a drum accommodating the object to be dried, a driving source for driving the drum, heating means for heating air introduced into the drum, and a blower unit for sucking or discharging air in the drum.

 The dryer may be classified into an electric dryer and a gas dryer according to a method of heating air, that is, a heating means. The electric dryer heats air using electric resistance heat, and the gas dryer heats air using heat generated by combustion of gas. If the dryers are classified differently, they can be classified as condensation dryers and exhaust dryers. In the condenser dryer, the air that has been heat-exchanged with the dry matter in the drum is circulated without being discharged to the outside of the dryer, and in a separate condenser, heat is exchanged with the outside air to make condensate and discharged to the outside. In the exhaust dryer, the air, which has been heat exchanged with the dry matter in the drum and becomes humid, is discharged directly to the outside of the dryer. If the dryer is classified into another method, it may be divided into a top loading method and a front loading method according to a method of inputting a dry matter to the dryer. In the top loading method, the dry material is introduced from the upper side of the dryer. In the front loading method, the dry material is injected from the front of the dryer.

Therefore, the hot air heater 90 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. Referring to Figure 3, the steam generator 200 will be described in detail as follows.

The steam generator 200 includes a water tank 210 for receiving water therein, a heater 240 mounted inside the water tank 210, and a water level sensor 260 for measuring the water level of the steam generator 200. And a temperature sensor 270 for measuring the temperature of the steam generator 200. The water level sensor 260 is generally composed of a common electrode 262, a low level electrode 264, and a high level electrode 266, so that the common electrode 262 and the high level electrode 264 are energized or the common electrode 262 and the low level electrode A high water level and a low water level are detected by the energization of 266.

One side of the steam generator 200 is connected to a water supply hose 220 for supplying water, and the other side is connected to a steam hose 230 for discharging steam, and a nozzle having a predetermined shape at the tip of the steam hose 230. 250) is preferably provided.

Meanwhile, in the present embodiment, the steam generator 200 (hereinafter, referred to as a "heating heating method") of a method of generating steam by heating a predetermined amount of water contained in the water tank 210 of a predetermined size with the heater 240 is referred to. Although shown and described, this invention is not limited to this. That is, in the present invention, any device capable of generating steam can be used as a steam generator. For example, it is also possible to install a heater directly around the water supply hose through which the water passes, that is, to heat the water without accommodating the water in a predetermined space (hereinafter referred to as "tube heating method" for convenience).

Referring to Figure 4, another embodiment of the steam dryer according to the present invention will be described.

In this embodiment, the water supply source for supplying water to the steam generator 200 is removable. As in the embodiment described above, the water supply may be a faucet, but in this case the installation is complex. This is because steam dryers usually do not use water, so when using a faucet as a water supply source, it is necessary to additionally install various devices. Therefore, as in the present embodiment, using a detachable water supply source (Detachable Water Supply Source) 300, the water supply source 300 is supplied to supply water, steam the water supply source 300 filled with water It is very convenient to connect to the water supply passage of the generator 200, that is, the water supply hose 220.

However, in general, various parts and the like of the steam dryer is a standard product and because it is compactly designed, there is absolutely no shortage of structural space. Therefore, water supply using water parking is virtually impossible without changing the size of various components of the conventional dryer. Therefore, when the small pump 400 is used, since the steam generator 200 or the like can be installed without changing the size of various parts of the conventional dryer, it is very useful to use the pump 400. And, the reason for recovering the residual water of the steam generator 200 is that if the steam generator 200 is not used for a long time, the heater may be damaged by the residual water, or there may be a possibility that the decayed water is used later.

In addition, in the above-described embodiment, water is supplied and steam is discharged from the upper portion of the steam generator 200, but in the present embodiment, water is supplied to the lower portion of the steam generator 200, and the steam generator 200 Steam is preferably discharged from the top. This configuration is advantageous for recovering the residual water of the steam generator 200.

In addition, it is preferable that the safety valve 500 is provided in the steam flow path for discharging steam from the steam generator 200, that is, the steam hose 230.

5 is an exploded perspective view showing an example of the water supply source of FIG. Hereinafter, the detachable water supply source 300 (hereinafter referred to as "cartridge") will be described in detail with reference to FIG. 5.

The cartridge 300 includes a lower housing 310 that substantially receives water, and an upper housing 320 that is detachable from the lower housing 310. When the cartridge 300 is configured as the lower housing 310 and the upper housing 320, it is easy to clean the scales accumulated in the cartridge 300, and the filters 302 and 303 and the softening member 305 may be cleaned. This is because it is easy to separate and clean or recycle.

It is preferable that the first filter 302 is installed in the upper housing 320. That is, it is preferable that the first filter 302 is installed at the water inlet of the upper housing 320 so that water is primarily filtered when water is supplied to the cartridge 300.

The lower housing 310 is provided with an opening and closing member 304 for selectively supplying the water of the cartridge 300 to the outside, when the cartridge 300 is separated, the water of the cartridge 300 is discharged to the outside If the cartridge 300 is installed, the water of the cartridge 300 is preferably discharged to the outside. In addition, the opening and closing member 304 is preferably connected to the second filter 303 for filtering the water, the second filter 303 is more preferably detachable. By using the first filter 302 and the second filter 303, impurities mixed in water such as fine dust may be filtered twice. Preferably, the first filter 302 uses about 50 mesh nets, and the second filter 303 uses about 60 mesh nets. Here, the 50 mesh network means that the number of meshes per predetermined area is 50. Therefore, the size of the pores constituting the mesh of the first filter 302 is larger than the size of the pores of the second filter 303, so that large foreign substances are removed. The first filter 302 is primarily filtered, and small foreign matter is filtered by the second filter 303.

In addition, it is preferable that a softening member 305 is further provided inside the cartridge 300 to soften water. In addition, the softening member 305 is more preferably detachable. As shown in FIG. 6, the softening member 305 includes a lower housing 306 in which a plurality of through holes are formed, and an upper housing 307 detachable from the lower housing 306 and in which a plurality of through holes are formed. It is preferably configured to include an ion exchange resin (not shown) filled in the space defined by the upper housing 307 and the lower housing 306.

The reason for using the softening member 305 is as follows. When the water supplied to the steam generator 200 has a high hardness, lime (calcium carbonate (CaCO ₃ ), etc.) is precipitated when calcium hydrogen carbonate (Ca (HCO ₃ ) ₂ ) dissolved in water is heated. This may cause corrosion of the heater. In particular, in Europe and the Americas, this phenomenon may be severe because water is a soft soft water. Therefore, it is preferable to remove calcium, magnesium ions, etc. in advance using an ion exchange resin to prevent the precipitation of lime. In addition, since the performance decreases as the soft water progresses, the ion exchange resin can be regenerated and reused with salt (NaCl). For reference, the softening process by ion exchange resin is 2 (R-SONa) + Ca2 <-> (R-SO) Ca + 2Na, and the regeneration process is (R-SO) Ca + 2NaCl <-> 2 (R -SONa) + CaCl.

In addition, the user's convenience may be enhanced in that the cover 340 does not need to be held so as not to be closed.

However, the hinge unit 350 according to the present embodiment is merely an embodiment for fixing the cover 340 when the cover 340 is rotated and opened by a predetermined angle or more, and performs the above function. Other embodiments of the hinge unit 350 are also possible, and the other embodiments are also included in the spirit of the present invention.

12 is a view schematically showing another embodiment of the hinge portion. Compared to the embodiment shown in FIG. 7, the hinge part 350 according to the present embodiment differs only in that a separate hinge axis and an elastic member are further included. Reference numerals and descriptions are used.

12, a hinge shaft 355 inserted into the pair of hinge holes 352 through a hole (not shown) formed at one side of the cover 340 in the hinge part 350 according to the present embodiment. And an elastic member 370 installed on the hinge shaft 355 to generate an elastic force in a direction in which the cover 340 is opened.

The elastic member 370 may generate an elastic force, and a body portion 371 fitted to the hinge shaft 355 and end portions 372 and 373 extending a predetermined length from the body portion 371 may be formed. One side 372 of the end portion is in close contact with the cover 340, the other side 373 of the end is in close contact with the upper housing 320. Then, the elastic member 370 may generate an elastic force in a direction away from the upper housing 320, that is, in a direction in which the cover 340 opens.

Accordingly, when the user wants to open the cover 340 to supply water, the cover 340 is closed, that is, the locking jaw 342 is caught on the bleeding jaw 323. It is only necessary to force the cover 340 upward through the gripping groove 324 and the opening groove 343. That is, as long as the locking jaw 342 is caught by the grip jaw 323 by the force of the user, the cover 340 is automatically provided by the elastic force of the elastic member 370. 321 may be opened in a completely open state, and once opened, may be maintained in an open state by the elastic force of the elastic member 370. When the water supply is finished, the catching jaw 342 may be caught by the catching jaw 323 again to close the cover 340. In this case, despite the elastic force of the elastic member 370, the cover 340 may be fixed in a closed state.

That is, according to the hinge part 350 according to the present embodiment, the cover 340 is automatically opened completely and at the same time, it can be maintained in the state after being completely opened, thereby improving user convenience.
