Dryer {laundry dryer}

The present invention relates to a dryer, and more particularly, to a dryer that can remove or prevent wrinkles or wrinkles that occur in clothes, and the like, and in particular, to prevent internal short circuit by water supplied to generate steam for removing wrinkles. It is about the dryer which can be done.

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

In general, the laundry is dried and dehydrated laundry is put into the dryer to dry. However, due to the principle of water washing, washing is completed, the wrinkles (wrinkles, wrinkles, folds, etc. collectively referred to as "wrinkling") is generated, the generated wrinkles are not completely removed in the drying process in the dryer.

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

The steam supply device receives water and electricity from a water supply source from the outside to generate steam and supply the steam to the drum.

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

In addition, in the case of the front-loading drum dryer, the steam supply device and the water supply source are provided in the remaining space after mounting the drum inside the limited-size housing, and when the drum is mounted by the front loading method, the upper and lower left and right sides Can be installed in the corner space.

The rear cover 18 is provided with an inlet 182 for allowing outside air to flow therein and an exhaust hole 184, which is 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 proceeds, and the lift 22 is installed inside the drum 20 by dragging and dropping the dry object to invert the dry object to increase the drying efficiency. desirable.

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 for preventing leakage between the front supporter 30 and the rear supporter 40 and the drum 20, respectively. A member (not shown) is provided. 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 164. 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. 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. In general, the blower unit 60 includes a blower 62 and a blower housing 64, and the blower 64 is generally connected to and driven by a motor 70 for driving the drum 20.

The rear supporter 40 is formed with an opening 42 which is usually composed of 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 to serve as a passage for supplying hot air to the drum 20. Therefore, the 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, and a nozzle having a predetermined shape is connected to the tip of the steam hose 230. Preferably, 250 is provided. In general, one end of the water supply hose 220 is connected to an external water source such as a faucet, and the tip of the steam hose 230 or the nozzle 25, that is, the steam discharge port, is positioned at a predetermined position of the drum 20, so that the drum 20 Steam is injected into the inside of the tank.

Meanwhile, in the present exemplary embodiment, the steam supply apparatus 200 of the method of generating steam by heating a predetermined amount of water contained in a water tank having a predetermined size with the heater 240 is illustrated 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 a steam supply device. For example, it is possible to use a method in which a heater is directly installed around a water supply hose through which water passes, that is, the water is heated without accommodating water in a predetermined space.

The water supply hose 220 for supplying water from one side of the steam supply device 200 may be supplied with water from an external tap water, or may be supplied with water from a cartridge-type water supply source 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 correspond to the change in the position of the steam supply device 200.

When the water supply hose is ruptured by the internal water pressure, the water supply hose 220 ejects water in an irregular direction at the rupture portion. On the rear surface of the control panel 19, the electrical component 191 in the form of a substrate on which various electronic components are mounted is located. The electronic parts 191 are electrically connected to each electronic component by a method such as welding.

Therefore, as described above, there is a need for a method of preventing water from being blown out to the electric field unit 191. Dryer according to the present invention is provided with a damping prevention plate, in order to prevent the damping to the electric portion 191, when the water supply hose 220 is ruptured.

The damping prevention plate 171 of the dryer according to the present invention shown in FIG. 2 is provided in the top cover 17 forming the cabinet 10. The check valve 171 may be configured integrally with the top cover 17, or may be separately mounted.

The position, shape, installation angle, etc. of the check valve 171 may vary depending on the position and connection relationship of the steam supply device 200 and the water supply hose 220.

That is, the water supply source and the steam supply device will be connected by a water supply hose in the form of a tube, and the damping prevention plate means that it is mounted at a position that blocks the electric parts and the water supply hose. That is, it serves to separate the space between the electrical equipment and the water supply hose.

However, since the control panel is often located above the front cover 16 forming the front surface of the cabinet 10, the position of the water damping plate 171 is the steam supply device 200 and the water supply hose 220. It is preferable to determine after the position of the back) is determined.

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

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

As in the embodiment described above, the water supply may be a faucet, but in this case the installation is complex. This is because, in general, water is not used in a dryer, and therefore, when a faucet is used as a water supply source, it is necessary to additionally install various devices and the like.

In an embodiment of the present invention, the detachable water supply, which is not the case when the water supply is connected to the tap water, is preferably understood as a concept including a cartridge 300 for receiving water. The cartridge 300 may be directly attached to or detached from the outside, and may be accommodated in a drawer to be described later, supported by the drawer guide, and guided. Therefore, the water supply source is used as a concept that includes all of the drawer or drawer guide is provided.

Therefore, as in the present embodiment, using a detachable water supply source (Detachable Water Supply Source), the cartridge 300 is supplied to supply water, and the water supply source filled with water to the water of the steam supply device 200 It is convenient to connect to the supply passage, that is, the water supply hose 220.

In addition, the pump 400 is preferably provided between the water supply source and the steam supply device 200. The pump 400 may be rotated forward and backward, and more preferably, water may be supplied to the steam supply device 200 and the remaining water of the steam supply device 200 may be recovered as necessary. It is also possible to supply water to the steam supply device 200 by using a water order between the water supply source and the steam supply device 200 without using the pump 400.

However, in general, various parts and the like of the dryer are standard products and are designed to be compact, so that the structural space is absolutely insufficient. 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 supply device 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 supply device 200 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 there is a possibility that the decayed water is used later.

In addition, it is preferable that the safety valve 500 is provided in the steam flow path that discharges steam from the steam supply device 200, that is, the steam hose 230.

3 is a front view of a dryer having a detachable water supply in an embodiment of the present invention, and FIG. 4 is a view illustrating a coupling relationship between a water supply source, a steam supply device, a water supply hose, and a check valve of the dryer according to the present invention. Doing.

As shown in Figure 3, the nozzle 250 is installed adjacent to the opening 42 for supplying hot air to the drum, it is shown that the steam is injected from the rear of the drum to the front.

When steam is injected from the rear to the front of the drum, air inside the drum normally flows from the opening 42 formed in the rear supporter 40 to form a lint duct below the door 104 (not shown, see FIG. 1). Since the air flows out of the furnace, the air flow path becomes a lint duct at the opening portion 42. Therefore, when the nozzle 250 is installed adjacent to the opening portion 42, the injected steam flows smoothly along this air flow path, so that it is evenly applied to the cloth.

On the other hand, the nozzle 250 described in this embodiment can be applied in addition to the dryer having a removable water supply source. For example, it is also applicable when an external faucet is used as the water supply.

Referring to FIG. 4 again, a drawer-type container (hereinafter referred to as a “drawer”) 700 capable of drawing in / out at a predetermined position of the dryer is installed, and the cartridge 700 is installed in the drawer 700. 300) is 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 indirectly drawn in / out of the drawer 700. It is preferable to couple / disconnect to the connector 480.

The supporter frame 820 is installed at the rear side of the control panel 19. That is, the supporter frame 820 is installed to be substantially parallel to the top frame 830, and the drawer guide 710 for guiding and supporting the drawer 700 in the supporter frame 820 and the top frame 830. Is preferably installed, the upper portion of the drawer guide 710 is more preferably provided with a top guide 810.

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

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

As described above, when the water supply hose is ruptured by the internal water pressure, the water supply hose 220 ejects water in an irregular direction at the rupture portion. On the rear surface of the control panel 19, the electrical component 191 in the form of a substrate on which various electronic components are mounted is located. The electronic parts 191 are electrically connected to each electronic component by a method such as welding.

Therefore, as described above, there is a need for a method of preventing water from being blown out to the electric field unit 191.

In contrast to the embodiment shown in FIG. 1, in the embodiment shown in FIG. 4, the check valve 821 is mounted to the supporter frame 820 instead of the top cover.

The position where the damping prevention plate 821 is installed in the supporter frame 820 is a position for preventing the damping of the water supply hose 220 to the electric part 191, the water supply hose and the steam supply device After the installation of the 200, the installation of the water supply hose is to be considered after rupture and considering the position of the electric part 191.

In the embodiment shown in Figure 4, the check valve 821 is provided in a position to prepare the rupture of the water supply hose 220 for connecting the pump 400 and the steam supply device 200.

In the embodiment shown in Figure 4, the water supply hose 220 is excessively bent, corresponding to the position of the steam supply device 200. Therefore, in the case of long-term use, it may rupture or the coupling part with the steam supply device 200 may be separated, and water may be ejected to the surroundings.

Therefore, the damping prevention plate blocks the water that is ejected, there is an effect that can prevent a short circuit in the electrical portion 191.

Therefore, the damping plate of the dryer according to the present invention can be seen to prepare for the rupture of the pipes connecting between the water supply source and the steam supply device, whether the water supply source is removable cartridge form, or the form of directly connecting the water from the outside Either is a technology that can be applied.

As such, it can be seen that the position of each check valve is variable according to each condition.

In the embodiment shown in FIG. 4, when the cartridge 300 is mounted in the drawer 700, at least both sides of the cartridge 300 correspond to both sides of the drawer 700, and are closely coupled to each other. It is preferable to be. In addition, recesses 301 are formed on both sides of the cartridge 300 to detach the cartridge 300, and the cartridge 700 may be detached using the recesses 301.

When the user withdraws the drawer 700, the cartridge 300 is also withdrawn. In this state, the cartridge 300 is removed from the drawer 700. Water is supplied to the cartridge 300 in the removed state through a water supply port, for example, the first filter 330, to fill the cartridge 300 with water. When the cartridge 300 in the water filled state is mounted in the drawer 700 again and the drawer 700 is pushed in, the cartridge 300 and the connection port 480 are automatically overlapped, so that the water of the cartridge 300 Open in the pump 400 direction.

After the use of the dryer, the cartridge 300 may be removed from the drawer 700 as opposed 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.

On the other hand, it is also possible to use the drawer 700 as a removable water supply source. However, when the drawer 700 is directly used as a detachable water supply, water may be inadvertently overflowed by the user when water is supplied to the drawer 700, but as described above, the detachable water supply source may be used. This can be prevented to some extent. When the drawer 700 is used as a directly detachable water supply source, there is an advantage that the structure can be simplified.

In addition, the damping prevention plate 191 prevents the rupture of the hose between the pump 400 and the steam supply device 200, as well as at the time of rupture of the hose, etc. connecting the water supply source and the pump that can be detached It is also possible to prevent bites.

The damper prevention plate installed in the supporter frame 820 may be integrally formed with the supporter. However, if the supporter frame 820 is made of metal, the damper prevention plate is made of plastic and is provided in a separate fastening means. It is preferable to mount by.

5 shows another embodiment of a dryer according to the invention. The damping prevention plate may be mounted on the top cover 17 of the dryer. The damping prevention plate 171 may be mounted on the top cover 17 to prevent the damping.

Unlike the embodiment shown in FIG. 2, in the embodiment shown in FIG. 5, the damp-proof plate 171 mounted to the top cover 17 is mounted perpendicular to the bottom surface of the top cover 17. This is because the position of the damping prevention plate 171 for preventing the damping according to the position of the water supply hose 220 and the electrical equipment is variable.

This is a convenient method when the position of the supporter frame 820 is not suitable for installing the check valve. The method of mounting the damping prevention plate 171 to the top cover 17 is also preferable to determine the location after the site where the hose is expected to burst after the steam supply device of the dryer and the water supply hose are combined. Do.

In addition, the damping prevention plate is a method that can be mounted separately to the top cover and a method of manufacturing integrally to the top cover.

The size and shape of the aforementioned various water barrier plates is not limited in the illustrated embodiment. That is, it is preferable to block the large and large area of the check valve, but it is not preferable in terms of cost, so it is economical to select the size experimentally.

Figure 6 shows another salsi example according to the present invention. In the embodiment shown in Figure 6, the damping prevention plate to prevent the damping to the electrical portion may be installed on the back of the front cover.

Since the electric component 191 is located on the rear surface of the control panel 19, it is preferable that the electric component 191 is formed in a removable cover shape covering the electric component.

When the fault occurs in the electric part 191, the electric part 191 needs to be replaced or repaired, and therefore, the damper preventing plate 1911 covering the electric part is preferably configured to be detachable by a coupling means or the like. .

In the embodiment shown in Figure 6, the check plate 1911 has a cross-sectional shape of 'b', and has a cover shape mounted on the back of the control panel 19 by screws or the like.

In the above-described embodiment, each check valve has a different mounting position. However, the idea of the common invention is that the short circuit accident can be prevented in the electrical parts by selecting the optimal position and mounting the damper prevention plate so as to prevent the damping with the electrical parts 191.

Of course, there may be other methods that can prevent water from getting to the electric parts 191 in a more robust manner, but it can be said that there is a feature of the present invention as a method of minimizing the increase in cost.

Although the present specification has been described with reference to preferred embodiments of the invention, those skilled in the art may variously modify and change the invention without departing from the spirit and scope of the invention as set forth in the claims set forth below. It could be done. Therefore, it should be seen that all modifications included in the technical scope of the present invention are basically included in the scope of the claims of the present invention.
