BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer, and more particularly, to a dryer capable of removing or preventing wrinkles, creases, The present invention relates to a dryer capable of performing a drying operation.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dryer, and more particularly, to a dryer capable of removing or preventing wrinkles, creases,

The dryer is a home appliance in which laundry, which is normally laundered, is dried by using high-temperature air. Generally, the dryer includes a drum for containing the laundry, a driving source for driving the drum, heating means for heating the air flowing into the drum, and a blower unit for sucking or discharging the air inside the drum.

 The dryer can be classified into an electric dryer and a gas dryer according to the heating method of heating the air. The electric dryer heats the air using electric resistance heat, and the gas dryer heats the air using the heat generated by the combustion of the gas. Different types of dryers can be classified as condenser dryers and exhaust dryers. In the condensing dryer, the air in the drum is heat exchanged with the laundry, and the air in a highly humid condition circulates without being discharged to the outside of the dryer. In the separate condenser, heat is exchanged with the outside air to generate condensed water. In the exhaust type dryer, the air in the drum is heat-exchanged with the laundry, and the air in a highly humid condition is directly discharged to the outside of the dryer. The dryer can be classified into top loading type and front loading type according to the method of loading the drying object into the dryer. In the top loading method, the laundry is loaded at the top of the dryer, while in the front loading method, the laundry is loaded at the front of the dryer.

Generally, in the dryer, the dehydrated laundry is introduced and dried. However, wrinkles (wrinkles, wrinkles, creases, etc.) are generated in the laundry after the water washing is completed in principle due to the principle of water washing, and the generated creases are not completely removed in the drying process in the dryer.

In order to remove such a crease, a steam supply device may be provided in the dryer to remove wrinkles generated during the drying process.

The steam supply device supplies water and electricity to the water supply source from the outside to generate steam, and supplies the steam to the inside of the drum.

Therefore, a steam supply device for supplying steam and a water supply source should be provided in the dryer housing.

Also, in the case of the drum loading device of the front loading type, the steam supply device and the water supply source are provided in a space where the drum is mounted inside the housing having a limited size. When the drum is mounted by the front loading type, It can be installed in the corner space.

It is preferable that the steam supply device and the water supply source are connected by a pipe and that the length of the pipe is not long. Therefore, it is preferable that the steam supply device and the water supply source are installed close to any one of the spaces of the upper and lower left and right corners, As described above, when the water supply source is configured as a detachable cartridge, it can be positioned on the side of the front side, and the steam supply device will be located in the rear space.

In addition, the water supply source may connect the water supply from the outside, and in the case of the dryer other than the washing machine, since a large amount of water is not required, a water supply source in the form of a cartridge can be used .

In the latter case, the water supply source in the form of a cartridge is connected to the steam supply device by piping such as a rubber tube to supply water.

However, the dryer having such a steam supply device has the following problems. The dryer generates a constant vibration due to the rotation of the drum or the like, and such vibration weakens the connection between the respective parts.

The steam supply device and the water supply source use a rubber tube or the like to flexibly cope with the position of the boom boom. The rubber tube or the like is connected to the steam supply device and the water supply source, but can be ruptured by continuous vibration or the like.

The water supply source and the steam supply device may be supplied with water by the water level difference, but may be connected through a pump by a restriction on the installation space (for example, the same height). Accordingly, when the tube or the like is ruptured under a constant water pressure and a certain water pressure is applied, the water is dispersed into the housing at the ruptured portion of the tube.

In general, the control panel for controlling the operation of the dryer is provided with a full-length portion on its rear surface.

When the tube is ruptured, water in the tube is blown into the dryer, connected to the control panel, mounted on a substrate or the like, and water ejected to a front part including electronic parts located inside the housing reaches a short- Line) may occur.

On the other hand, a steam supply device 200 for generating steam at a high temperature is installed at a predetermined position of the cabinet 10. In this embodiment, the indirect driving method for rotating the drum 20 using the motor 70 and the belt 68 is shown and described for the sake of convenience, but the present invention is not limited thereto. That is, it is also possible to apply the present invention to a direct drive type in which the motor is directly connected to the rear surface of the drum 20 to rotate the drum 20 directly.

Each component will be described in detail as follows.

The cabinet 10 forms the outer shape of the dryer and includes a base 12 forming a bottom surface, a pair of side covers 14 vertically installed in the base 12, A front cover 16 and a rear cover 18 disposed on the front and rear surfaces of the side cover 14 and a top cover 17 disposed on the top of the side cover 14, respectively. The control panel 19 having various operation switches is usually located in the top cover 17 or the front cover 16 and the door 164 is installed in the front cover 16. [ The rear cover 18 is provided with a suction portion 182 for allowing external air to flow in and an exhaust hole 184 as a final passage through which the air of the drum 20 is discharged to the outside.

The inner space of the drum 20 functions as a drying chamber in which drying is progressed, and a lift 22 is installed inside the drum 20 to raise the drying object, desirable.

On the other hand, a front supporter 30 and a rear supporter 40 are provided between the drum 20 and the cabinet 10 (the front cover 16 and the rear cover 18). A drum 20 is rotatably installed between the front supporter 30 and the rear supporter 40. Between the front supporter 30 and the rear supporter 40 and the drum 20, A member (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 end and the rear end of the drum 20.

The front supporter 30 is provided with an opening for communicating the drum 20 with the outside of the dryer, and the opening is selectively opened and closed by the door 164. The front supporter 30 is connected to a lint duct 50 which is a passage through which the air of the drum 20 is discharged to the outside and a lint filter 52 is installed in the lint duct 50. One side of the blower unit 60 is connected to the lint duct 50 and the other side of the blower unit 60 is connected to the exhaust duct 80. The exhaust duct 80 is connected to the rear cover 18 And communicates with the exhaust hole 184 provided therein. Therefore, when the blower unit 60 is operated, the air inside 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 by the lint filter 52. Generally, the blower unit 60 includes a blower 62 and a blower housing 64. The blower 64 is connected to a motor 70 for driving the drum 20 and is driven.

The rear supporter 40 is generally formed with an opening 42 having a plurality of through holes and the hot air supply duct 44 is connected to the opening 42. The hot air supply duct 44 communicates with the drum 20 and serves as a passage for supplying hot air to the drum 20. [ Therefore, a hot air heater 90 is installed at a predetermined position of the hot air supply duct 44.

A water supply hose 220 for supplying water is connected to one side of the steam supply device 200 and a steam hose 230 for discharging steam is connected to the other side of the steam supply device 200. A nozzle It is preferable that the light guide plate 250 is provided. The tip of the steam hose 230 or the nozzle 25 or the steam discharge port is positioned at a predetermined position of the drum 20 so that the drum 20 The steam is sprayed to the inside of the steam generator.

Meanwhile, in the present embodiment, a steam supply device 200 for generating a steam by heating a predetermined amount of water contained in a water tank of a predetermined size with a heater 240 has been shown and described, but the present invention is not limited thereto. That is, in the present invention, any device capable of generating steam can be used as the steam supply device. For example, it is also possible to use a method in which a heater is directly provided around the water supply hose through which water passes, that is, a method in which water is heated without containing water in a predetermined space.

The water supply hose 220 for supplying water from one side of the steam supply device 200 may receive water from the external water supply source and supply water from a water supply source in the form of a cartridge to be described later. The water supply hose 220 is preferably made of a flexible material such as a rubber tube in order to easily respond to a change in the position of the steam supply device 200.

When the water supply hose ruptures due to the water pressure inside the water supply hose 220, water is ejected in an irregular direction at the ruptured portion. On the rear surface of the control panel 19, a front portion 191 in the form of a board on which various electronic components are mounted is positioned. The electronic components 191 are electrically connected to each other by a method such as welding.

Therefore, as described above, there is a need for a method capable of preventing short-circuiting by spraying water onto the front portion 191. The dryer according to the present invention is provided with a dust prevention plate to prevent dust from coming into the electric storage unit 191 when the water supply hose 220 ruptures.

2 is provided on the top cover 17 constituting the cabinet 10. The dust cover 171 of the dryer according to the present invention shown in FIG. The dirt prevention plate 171 may be integrally formed with the top cover 17 or may be separately mounted.

The position, shape, installation angle, and the like of the dirt prevention plate 171 are variable according to the position and connection relation of the steam supply device 200 and the water supply hose 220.

That is, the water supply source and the steam supply device are connected to each other by a tube-shaped water supply hose, and the water stopping plate is mounted at a position where the water supply hose and the water supply hose are blocked. In other words, it plays a role of separating the space between the front part and the water supply hose.

2, the control panel 19 protrudes from the top cover 17 and is mounted diagonally for the convenience of the user. Therefore, the dust cover prevention plate 171 is horizontally Respectively.

However, since the control panel is located above the front cover 16 forming the front surface of the cabinet 10, the position of the dirt prevention plate 171 is different from that of the steam supply device 200 and the water supply hose 220 ) Is determined after the determination of the position is determined.

3 is a front view of another embodiment of a dryer according to the present invention.

In the embodiment shown in FIG. 3, a water supply source for supplying water to the steam supply device 200 is detachable. That is, a water supply source is provided in the form of a detachable cartridge.

As in the previous embodiments, the water source may be a faucet, but in this case the installation is complex. This is because water is not usually used in a dryer, and therefore, when a faucet is used as a water supply source, it is necessary to additionally provide a variety of apparatuses associated therewith.

In an embodiment of the present invention, it is preferred that the removable water source, rather than when the water source is connected to the water line, is understood to include a cartridge 300 that receives water. The cartridge 300 may be detached and attached directly to the outside, may be accommodated in a drawer to be described later, supported by a drawer guide, and may be guided. Accordingly, the water supply source is used as a concept including both drawer and drawer guides.

Therefore, as in the present embodiment, the detachable water supply source is used to separate the cartridge 300 to supply water, and the water supply source for supplying water to the water supply unit 200 It is convenient to connect it to the supply passage, that is, the water supply hose 220.

In addition, it is preferable that a pump 400 is provided between the water supply source and the steam supply device 200. It is more preferable that the pump 400 is rotatable in the forward and reverse directions so that it is possible to supply water to the steam supply device 200 and recover the residual water of the steam supply device 200 as necessary. It is also possible to supply water to the steam supply device 200 by using a water pump between the water supply source and the steam supply device 200 without using the pump 400.

However, in general, various components of a dryer are standard products and are designed to be compact, so that a structural space is absolutely lacking. Therefore, it is practically impossible to feed water by using a parking lot unless the size of various parts of the conventional dryer is changed. Therefore, when the small pump 400 is used, it is very useful to use the pump 400 because the steam supply device 200 and the like can be installed without changing the size of various types of conventional dryers.

The reason why the residual water of the steam supply device 200 is recovered is that if the steam supply device 200 is not used for a long time, the heater may be damaged by the residual water or the water may be corrupted in the future.

Also, it is preferable that a safety valve 500 is provided in the steam passage 230 for discharging steam from the steam supply device 200.

Fig. 3 is a front view of a dryer having a detachable water supply source in the embodiment of the present invention. Fig. 4 is a view showing a connection relationship between a water supply source, a steam supply device, a water supply hose, .

As shown in FIG. 3, the nozzle 250 is disposed adjacent to the opening 42 for supplying hot air to the drum, so that steam is sprayed from the rear to the front of the drum.

When steam is sprayed from the rear side of the drum to the front side, the air in the drum normally flows in the opening 42 formed in the rear supporter 40 and flows into the lint duct (not shown in FIG. 1) So that the flow path of the air almost becomes the lint duct at the opening portion 42. As shown in Fig. Accordingly, when the nozzle 250 is installed adjacent to the opening 42, the sprayed steam flows smoothly along the air flow path, and thus the steam is evenly applied to the cloth.

Meanwhile, the nozzle 250 described in this embodiment can be applied to a dryer other than a dryer having a detachable water supply source. For example, an external faucet may be used as a water source.

Referring to FIG. 4 again, a drawer container 700 (hereinafter, referred to as "drawer") capable of being drawn in / out at a predetermined position of the dryer is installed, 300 are mounted.

That is, rather than connecting the cartridge 300 directly to the connection port 480, the cartridge 300 is mounted on the drawer 700 and the drawer 700 is drawn / It is preferable to couple / separate the connection port 480.

A supporter frame 820 is provided to the rear side of the control panel 19. [ That is, the supporter frame 820 is installed substantially in parallel with the top frame 830 and includes a drawer guide 710 for guiding and supporting the drawer 700 to the supporter frame 820 and the top frame 830, And a top guide 810 may be provided on an upper portion of the drawer guide 710. [

The supporter frame 820 and the top frame 830 serve as a frame of the dryer and can be used as a mounting place where a water supply source or a steam supply device can be mounted.

The drawer 700 may be provided on the front side of the dryer, for example, next to the control panel 19.

As described above, when the water supply hose ruptures due to the water pressure inside the water supply hose 220, water is ejected in an irregular direction at the rupture area. On the rear surface of the control panel 19, a front portion 191 in the form of a board on which various electronic components are mounted is positioned. The electronic components 191 are electrically connected to each other by a method such as welding.

Therefore, as described above, there is a need for a method capable of preventing short-circuiting by spraying water onto the front portion 191.

In contrast to the embodiment shown in Fig. 1, in the embodiment shown in Fig. 4, the dirt prevention plate 821 is mounted on the supporter frame 820 instead of the top cover.

Since the position where the dirt prevention plate 821 is installed in the supporter frame 820 is a position for preventing water from being leaked to the front portion 191 when the water supply hose 220 ruptures, The water hose 200 is installed after considering the part where the water hose is likely to rupture and the position of the front part 191.

In the embodiment shown in FIG. 4, the water stopping plate 821 is provided at a position to prevent rupture of the water supply hose 220 connecting the pump 400 and the steam supply device 200.

In the embodiment shown in FIG. 4, the water supply hose 220 is excessively bent, corresponding to the position of the steam supply device 200. Therefore, when used for a long period of time, the water can be ruptured or the joining portion with the steam supply device 200 can be separated, and water can be ejected to the periphery.

Therefore, the water stopping plate can block the water to be sprayed, thereby preventing short-circuiting in the front portion 191.

Therefore, the water-stopping plate of the dryer according to the present invention can be regarded as preparing for the rupture of the pipes connecting the water supply source and the steam supply device. Therefore, it is possible to provide a water- It is a technology that can be applied.

As described above, it can be confirmed that the positions of the respective water retention plates are variable according to the respective conditions.

4, when the cartridge 300 is mounted in the drawer 700, at least both side shapes of the cartridge 300 are closely coupled to each other, corresponding to both side shapes of the drawer 700. In this embodiment, . In order to attach and detach the cartridge 300, recesses 301 are formed on both sides of the cartridge 300, and the cartridge 700 is detachably attached using the recesses 301.

When the user pulls the drawer 700, the cartridge 300 is also pulled out. In this state, the cartridge 300 is detached from the drawer 700. Water is supplied to the cartridge 300 in a detached state by the water filter, for example, the first filter 330, and the cartridge 300 is filled with water. When the cartridge 300 filled with water is mounted on the drawer 700 and the drawer 700 is pushed in, the cartridge 300 and the connection port 480 are automatically overlapped with each other, And is opened toward the pump 400.

After completion of the use of the dryer, the cartridge 300 can be removed from the drawer 700, contrary to the above description. In the present invention, since the cartridge 300 is composed of the upper housing 320 and the lower housing 310, it is easy to clean the removed cartridge 300.

Meanwhile, it is also possible to use the drawer 700 as a water supply source that can be directly attached and detached. However, when the drawer 700 is directly used as a detachable water supply source, the user may inadvertently flood the drawer 700 at the time of water supply. However, as described above, This can be avoided to a certain extent. When the drawer 700 is directly used as a detachable water supply source, there is an advantage that the structure can be simplified.

The water stopping plate 191 prevents rupture of the hose between the pump 400 and the steam supply device 200 and also prevents the rupture of the hose connecting the water supply source and the pump, It is also possible to prevent water pollution.

In the case where the supporter frame 820 is made of metal, the embossing prevention plate may be made of plastic and may be attached to another fixing means .

Figure 5 shows another embodiment of a dryer according to the invention. The dirt prevention plate may be mounted on the top cover 17 of the dryer. The water stopping plate 171 can be attached to the top cover 17 to prevent water spillage.

In contrast to the embodiment shown in FIG. 2, in the embodiment shown in FIG. 5, the dirt prevention plate 171 mounted on the top cover 17 is vertically mounted on the lower surface of the top cover 17. This is because the position of the water stopping plate 171 for preventing water spouting is variable depending on the positions of the water supply hose 220 and the electric field part.

This is a convenient method when the position of the supporter frame 820 is not suitable for installing the dirt prevention plate. Also, it is preferable to determine the position of the hose after irradiating a part where the rupture of the hose is expected after the coupling of the steam supply device of the dryer and the water supply hose or the like, to the top cover 17 Do.

In addition, the waterproofing plate is a method of separately mounting the waterproofing plate on the top cover and a method of integrally manufacturing the waterproofing plate on the top cover.

The size and shape of the above-mentioned various anti-fouling plates are not limited in the illustrated embodiment. That is, it is preferable to block a large area and a large area of the waterproofing plate, but it is not preferable from a cost point of view, so it is economical to select the size of the waterproofing plate experimentally.

6 shows another example according to the present invention. In the embodiment shown in Fig. 6, a dust prevention plate for preventing dust from splashing on the electric field part may be provided on the back surface of the front cover.

Since the front portion 191 is located on the back surface of the control panel 19, it is preferable that the front portion 191 is formed as a removable cover which covers the electric field portion.

When the defective portion 191 is defective, the front portion 191 needs to be repaired such as replacing it, so that the dirt prevention plate 1911 covering the electrical portion is preferably configured to be detachable by a coupling means or the like .

In the embodiment shown in FIG. 6, the water stopper plate 1911 has a cross-sectional shape of 'C' and has a lid shape to be mounted on the back surface of the control panel 19 by screws or the like.

In the above-described embodiment, the respective anti-fogging plates have different mounting positions. However, the common idea of the invention is to prevent the short-circuit accident in the front part or the like by selecting the optimum position and mounting the water stopping plate so as to prevent water from being stuck to the front part 191.

Of course, there may be other ways of preventing water splashing to the front housing 191 in a more robust manner, but it can be said that there is a feature of the present invention as a way to minimize the cost increase.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims. . It is therefore to be understood that the modified embodiments are included in the technical scope of the present invention if they basically include elements of the claims of the present invention.
