It relates to a dryer having a positioning means for accurately determining the mounting position of the position, and a position fixing means that can be fixed firmly at the determined position.

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.

That is, it is also possible to apply the present invention to a direct drive method (Direct Drive Type) in which a motor is directly connected to the rear surface of the drum 20 to directly rotate the drum 20.

Each component will be described in detail as follows.

The cabinet 10 forms an outer shape of the dryer, and includes a base 12 forming a bottom surface, a pair of side covers 14 installed vertically from the base 12, and the side cover 14. The front cover 16 and the rear cover 18, which are respectively installed on the front and rear of the, is configured to include a top cover 17 located on the upper side of the side cover (14). The control panel 19 having various operation switches or the like is normally located on the top cover 17 or the front cover 16, and the door 164 is provided on the front cover 16. 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 front of the drum 20, the front cover 16, and the rear of the drum 20, and the rear cover 18, respectively. The drum 20 is rotatably supported by 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 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 provided at the rear cover 18. It communicates with the exhaust hole 184.

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.

On the other hand, at a predetermined position of the cabinet 10 is provided with a steam supply device 200 for generating steam to supply the interior of the drum (20).

3 is a coupling relationship between the steam supply device 200 and the water supply source.

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 or the nozzle 250, that is, the steam outlet of the steam hose 230, is positioned at a predetermined position of the drum 20, and thus the drum 20 Steam is injected into the inside of the tank.

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.

A water supply source for supplying water to the steam supply device 200 shown in FIG. 3 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 the embodiment of the present invention, the detachable water supply 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, by using a detachable water supply source (Detachable Water Supply Source), the cartridge 300 is supplied to supply water, and the water filled cartridge 300, the water supply flow path of the steam supply device 200, that is, the water supply hose It is convenient to connect to 220.

In addition, the pump 400 is preferably provided between the cartridge 300 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 apparatus 200 by using a water order between the cartridge 300 and the steam supply apparatus 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.

Further, in the above-described embodiment, although water is supplied and steam is discharged from the upper portion of the steam supply device 200, in the present embodiment, water is supplied to the lower portion of the steam supply device 200, and the steam supply device ( Steam is preferably discharged from the top of the (200). This configuration is advantageous for recovering the residual water of the steam supply device 200.

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.

As already described, the water supply may be external water or the like, but may be a detachable cartridge-type water supply as described below. Even if water is supplied to a detachable cartridge-type water supply source, it is not a washing machine but a dryer, so it does not have a large amount of water and can be installed in a place where a water pipe does not exist.

4 shows a front side of a dryer having a removable water supply of the present invention.

As shown in Figure 4, 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.

5 is a coupling relationship between the water supply source, the steam supply device and the frame of the dryer according to the present invention.

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 a cartridge 300 is mounted in the drawer 700.

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 820 is installed at the rear side of the control panel 19. That is, the supporter 820 is installed in substantially parallel with the top frame 830, the drawer guide 710 for guiding and supporting the drawer 700 on the supporter 820 and the top frame 830 is installed. It is preferable that the upper part of the drawer guide 710 is provided with a top guide 810.

The supporter 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.

5 shows that in the illustrated embodiment, when the cartridge 300 is mounted in the drawer 700, at least both side shapes of the cartridge 300 correspond to both side shapes of the drawer 700, and are closely coupled to each other. It is desirable 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.

A method of supplying water to the cartridge 300 is described below.

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.

The dryer according to the present invention rotates the drum in the drum, and supplies hot air or steam to dry the clothes in the drum and removes wrinkles. Thus, the dryer is shaken by continuous vibration.

In addition, the position of the water supply and the steam generator in the assembly process should be placed in the correct position. If the product is mounted out of the intended position during the product design, unexpected defects or the like may occur, and therefore, it is necessary to be mounted at the correct position.

In addition, there is a need for a means for fixing at the determined position even after determining the exact position.

Therefore, the dryer according to the present invention is provided with positioning means for determining the position of each water source and the steam generator and position fixing means for fixing the water supply and the steam generator at the determined position.

In the embodiment shown in Figure 5, the water supply is provided in the form of a removable cartridge. Therefore, the frame supporting the water supply source does not directly support the removable cartridge 300, but the drawer guide 710 for supporting and guiding the drawer 700 for accommodating the cartridge 300. It is.

In addition, as the supporter supports the drawer guide 710, the steam generator 200 is also supported together.

The frame for supporting the water supply source (excitation drawer guide) and the steam generator 200 is a top frame 830 provided at an inner corner of the housing and a supporter 820 provided at the rear of the control panel 19. .

As described above, the front-loading dryer uses a detachable water source instead of a water pipe connection, so the surplus space inside the hexahedron housing is the surplus space at the upper and lower corners except the space occupied by the waste, and is located above the lower portion. It is convenient to install a drawer in which the cartridge 300 is mounted. Since the length of the pipe connecting the water supply source and the steam generator 200 is not long, it is preferable to arrange the steam generator 200 in a row on the rear of the drawer guide 710.

In addition, a method of reducing the number of frames provided to reinforce the rigidity of the housing or to install various components is a method of sharing the same frame. Therefore, mounting the water supply source and the steam generator 200 on the same frame may bring cost saving effects.

Dryer according to the present invention is a positioning means as a means for determining the correct mounting position of the water supply source and the top frame 830 or the supporter 820 of the steam generator 200 is the steam supply device 200 or At least one of the water supply source and the frame passing through the upper portion of the protrusion formed on one side and the projection formed on the other side is formed with a groove or hole that can be inserted.

That is, a positioning means may be provided at both the water supply source and the steam generator 200, and at least one of the positioning means may be provided.

The positioning means is characterized in that the grooves or holes into which the projections formed on one side and the projections formed on the other side can be inserted.

When the part where the protrusion is formed is determined, a groove or a hole into which the protrusion may be inserted may be formed on the other side, and the position may be determined by inserting the protrusion into the groove or hole when the product is assembled.

In the embodiment of the present invention shown in Figure 5, the groove or hole into which the projection can be inserted is provided in the frame, such as the supporter, inserted into the hole in the coupling portion of the water supply source and the steam generator 200. Protruding protrusions are formed.

In addition, since the cartridge 300 is a removable cartridge, the protrusion 300 is formed on the draw guide 710 for guiding the drawer 700 in which the cartridge 300 is accommodated.

According to the partially enlarged view shown in FIG. 5, the first protrusion 712 and the second protrusion 202 are formed on the side of the steam generator 200, respectively, on the side of the drawer guide 710, and the supporter ( Holes or grooves corresponding to the first protrusion 712 and the second protrusion 202 are formed on the side surface of the 820.

In the embodiment shown in FIG. 5, the protrusions 712 and 202 are the first hole 822 and the second hole 823 formed in the supporter. Since each of the first protrusions is inserted into the first hole and the second protrusions are inserted into the second hole, it is possible to accurately determine the mounting position of the draw guide 710 and the steam generator 200, respectively.

In addition, the positioning guide of the drawer guide 710 and the steam generator 200 has been described only in relation to the supporter 820, but also in relation to the top frame 810 as well as the supporter 820. It is obvious that it can be applied.
