Description

Clothing processing equipment

The present invention relates to a clothing treatment device and a control method thereof. More specifically, it relates to a clothing treatment device and its control method that can supply steam and hot air to clothing to perform a refresh process such as sterilizing, removing wrinkles, deodorizing, and drying clothing.

Generally, a clothing treatment device is a home appliance that removes foreign substances from clothes using water and detergent, and includes a tub that stores water, a water supply unit that supplies water to the tub, and a flow path connecting the water supply unit and the tub. It includes a detergent supply unit disposed in and supplying detergent to the tub along with the water.

Conventional clothing treatment devices could simply be equipped with the detergent supply unit as a storage space for detergent, and a method of injecting the necessary detergent into the detergent supply unit each time a user washed clothes was applied.

Although these conventional clothing treatment devices were able to guarantee the user the autonomy to select the type and amount of detergent needed, there was a fundamental problem in that it was difficult to expect the input of the required amount of detergent.

Additionally, in this type of clothing treatment device, when the detergent supply buoy receives water, all the detergent stored in the detergent supply buoy is injected into the tub, so there is also the inconvenience of having to inject new detergent every time laundry is performed.

To overcome this problem, a clothing treatment device has emerged in which the detergent supply unit is controlled by a control unit provided in the clothing treatment device to supply an appropriate amount of detergent. (Refer to Korean Patent Publication No. 2000-0009638)

The conventional clothing treatment apparatus is equipped with an automatic detergent supply device including a detergent box in which the detergent supply unit stores detergent, and a valve that automatically supplies the detergent contained in the detergent box to the tub.

This type of clothing treatment device has the advantage that the control unit can calculate the optimal amount of detergent according to the amount of laundry, water supply, etc., so that only an appropriate amount of detergent can be supplied to the tub even if a large amount of detergent is stored in the detergent box.

However, the laundry treatment device had a limitation in that the detergent box was integrated into the cabinet and the like and could not be separated. As a result, when foreign substances are introduced into the detergent box or are contaminated, the clothes treatment device cannot be washed separately, so there is a possibility that the automatic detergent supply device may be damaged or the clothes may be contaminated by the detergent stored in the detergent box.

In particular, the clothes treatment device had a fundamental limitation in that it was difficult to maintain and repair because there was no way to easily remove the wrong detergent or foreign matter if the user put the wrong detergent or foreign matter in the detergent box.

To overcome this problem, a clothing treatment device has emerged in which the detergent compartment can be separated from the clothing treatment device. (Korean Patent Publication No. 10-2021-0027019)

The laundry treatment device is equipped so that the detergent box can be separated from the flow path that supplies detergent and completely pulled out to the outside. Accordingly, there was an advantage that the detergent box could be easily cleaned if it was contaminated or foreign substances were added, and if other detergents or foreign substances other than a suitable detergent were added to the detergent box, it could be easily removed.

Meanwhile, a large amount of detergent must be added to the detergent box to reduce the number of times the user puts detergent into the detergent box. Because of this, the detergent box needed to be increased in volume to accommodate detergent capable of performing multiple washing cycles.

Conventional clothing treatment devices are equipped with a drawer-type housing that accommodates and supports the entire detergent box in order to stably support a heavy and bulky detergent box.

The housing has all closed surfaces except for the open surface from which the detergent box is pulled out, so that it can support more than four sides of the detergent box. As a result, the conventional laundry treatment device was able to stably support the detergent box even when large vibrations occurred.

However, in order for the automatic detergent supply device to be equipped to completely accommodate the detergent box in the housing (hereinafter referred to as the drawer type), it must be equipped as a front load type with an opening at the front through which clothes are put in, like a conventional laundry treatment device. It was common.

The front load type washing machine has a drum accommodating clothes that rotates about a rotation axis that is parallel or slightly inclined to the ground, and a tub accommodating the drum is also provided in a cylindrical shape arranged in the front and rear directions. Therefore, in the conventional front load type washing machine, there was an advantage in that a space where the drawer type automatic detergent supply device could be installed could be secured at the front corner of the cabinet.

In particular, since the front load type washing machine does not have a door on the top, it also had the advantage of being able to install a separate automatic detergent supply device at the top of the cabinet.

However, this drawer-type automatic detergent supply device has a problem in that it is difficult to apply to a top-load type washing machine in which the clothes inlet is provided at the top of the cabinet.

Nevertheless, in recent years, clothes processing devices equipped with a drawer-type automatic detergent supply device have appeared in top-load type washing machines. (Refer to Korea Patent Publication No. 10-2018-0080013)

The clothes processing device applied a drawer-type automatic detergent supply device to a top-load type washing machine, which has an opening at the top of the cabinet through which clothes are put in, and a door that opens and closes the opening.

In a top-load type washing machine, since the suspension supporting the tub is fixed to the corner of the cabinet, it is difficult to install an automatic detergent supply device inside the cabinet, or even if installed, it is necessary to expand the capacity of the detergent box or install a water supply channel. There are difficulties.

Additionally, in a top load type washing machine, when the automatic detergent supply device is placed in front of the door or opening, it prevents putting clothes into the opening or opening the door.

Therefore, in the conventional clothing treatment apparatus, the automatic detergent supply device is placed at the rear of the door or opening, and the automatic detergent supply device is provided as a drawer type in which the detergent box is pulled out to the front.

However, the automatic detergent supply device requires the installation of a pump that discharges the detergent stored in the detergent box or a connection part that connects the pump and the detergent box. If the automatic detergent supply device is provided as a drawer type, the pump or connection part must be installed on the side opposite to the side where the detergent box is input, and as a result, the detergent box is installed on the back of the laundry treatment device. The connection must be spaced forward as much as the space where it must be installed.

That is, when a drawer-type automatic detergent supply device that is pulled out to the front is installed in a top-load type washing machine like a conventional laundry treatment device, a detergent box and a pump/connector are installed in the space from the rear of the cabinet to the back of the inlet or door. All configurations must be installed. As a result, the conventional clothing handling device had a fundamental problem in that the area of the opening or door was reduced, making it inconvenient to take in and take out clothes.

Moreover, the conventional clothes handling apparatus had a problem in that it was difficult to sufficiently secure the front-to-back thickness of the detergent box even if the area of the opening or door was reduced, and thus the volume of the detergent box could not be sufficiently enlarged.

To solve this problem, a drawer-type automatic detergent supply device in which the detergent box is pulled out to the top of the top-load type washing machine can be considered. In this case, since the pump/connection part is disposed at the bottom of the detergent box, the width of the detergent box in the front and rear directions is sufficiently secured and the area of the opening is not narrowed.

However, in top load type washing machines, the automatic detergent supply device must be placed rearward of the opening, making it difficult for users to access it. In this situation, if the detergent box is provided to be pulled out to the top, there is a problem that the physical condition of a typical user is not suitable to completely pull out the detergent box to the top of the drawer.

To improve this, a drawer-type automatic detergent supply device that has a detergent box pulled out to the side of a top-load type washing machine can be considered.

At this time, it may be easy to pull out the detergent box to the side, but the direction in which the detergent box is pulled out must be maintained until it is completely pulled out of the drawer. A wall is disposed on the side of the laundry treatment device, or another home appliance Due to this arrangement, if the length by which the detergent box can be pulled out is not secured, there is a problem that insertion and extraction of the detergent box becomes impossible.

As a result, there were fundamental limitations in conventionally installing a drawer-type automatic detergent supply device in a top-load type washing machine.

Meanwhile, it may be considered that the automatic detergent supply device of the top load type washing machine is provided in a slide coupling type rather than a drawer type. In other words, it can be considered that the detergent box is exposed and mounted on a mounting unit provided at the rear of the door or opening in the cabinet.

In this case, there is an advantage that the detergent box can be easily mounted on the mounting unit because the mounting/removing direction of the detergent box is not limited by the shape of the drawer.

For example, a method of attaching the detergent box to a mounting portion provided at the rear of the door at the top of the cabinet by inserting it from the top to the bottom may be considered. In this case, as the depth inserted into the lower part increases, the detergent box can be stably fixed to the mounting part, but it may be difficult to withdraw it from the mounting part.

Therefore, a method in which the detergent box slides a certain length from the side of the mounting unit toward the inside and is coupled to the mounting unit may be considered. In this case, there is an advantage that the detergent box can be easily mounted and removed from the mounting unit, but there is also a limitation that the detergent box can be arbitrarily detached from the mounting unit when vibration or the like occurs.

As a result, in a top-load type washing machine, the method in which the detergent box is exposed to the cabinet, slides in the width direction of the cabinet, and is mounted on the mounting part is the easiest to attach and detach the detergent box, so it is highly applicable.

However, the easier it is to install the detergent box in the mounting part, the easier it is for the detergent box to be separated from the cabinet. Therefore, there is a need for research into how to easily mount the detergent box and secure the detergent box stably.

In addition, since the detergent box can be easily pulled out, there is a need for a method to accurately detect whether the detergent box is fully coupled to the mounting unit.

The present invention aims to solve the problem of providing a laundry treatment device that can slide and support a detergent box that is detachably provided at the top of a top load type washing machine.

The present invention aims to solve the problem of providing a laundry treatment device that can be installed by sliding the detergent box in the width direction of the laundry treatment device.

The present invention aims to solve the problem of providing a laundry treatment device that can stably maintain the detergent box mounted even when only the lower part of the detergent box is fixed to the laundry treatment device.

The present invention aims to solve the problem of providing a laundry treatment device that can stably guide the combination and separation of the detergent box by guiding it to slide and be mounted.

The present invention aims to solve the problem of providing a laundry treatment device in which the detergent box can be mounted and detached even if there is no additional space for the detergent box to slide outside both sides of the laundry treatment device.

The present invention aims to provide a laundry treatment device that slides and mounts a detergent box, but is capable of completing installation and separation of the detergent box before the detergent box slides out of the laundry treatment device. Make it an assignment.

In order to solve the above-described problem, the present invention is provided with an automatic detergent supply device mounted on the top of a top load type washing machine, and the detergent box that stores detergent among the automatic detergent supply devices is slidably moved in the width direction of the top load type washing machine. It can be equipped to be mounted on a clothing processing device.

The laundry treatment device may have a mounting portion that can be mounted on the detergent box placed at the top of the cabinet. The mounting unit may be provided in a top cover that has an opening through which clothing is inserted.

The mounting unit may be disposed at the rear of the opening to prevent clothing from being inserted.

The mounting part may include a mounting groove that guides the detergent box to slide, and a communication part provided in the mounting groove to communicate with the detergent box.

The mounting groove may be arranged to be inclined downward toward the communication part. As a result, the detergent box can be prevented from leaving the mounting groove unless an artificial external force is applied due to gravity.

In addition, the mounting groove may be additionally provided with a stopper at an outer end to prevent the detergent box from being separated. As a result, the detergent box can be prevented from leaving the mounting groove unless the user artificially pulls it.

As a result, even if the detergent box is slid horizontally on the top cover to be coupled to or separated from the mounting unit, it can be prevented from being arbitrarily separated from or separated from the mounting unit.

The mounting groove may be provided to support only the lower part of the detergent box. For example, the mounting groove may be provided with an open top. Accordingly, when the detergent box is separated from the communication part, it can be immediately separated from the detergent box without additionally sliding in the mounting groove.

Specifically, the automatic detergent supply device is disposed at the rear of the door or the inlet and receives the detergent and delivers it to the tub. It accommodates the detergent supplied to the mounting portion, and the mounting portion is disposed in the width direction of the top cover.

Figure 1 shows an external example of the laundry treatment apparatus of the present invention.

The laundry treatment device 1 of the present invention may include a top cover 20 coupled to the upper part of the cabinet 10. The top cover 20 may form the upper surface of the clothing treatment device 1 and may be provided with an opening through which clothing is input.

The top cover 20 is a control panel having an input unit that receives a command to perform the course and a display unit that can externally display the status of the course being performed and the status of the automatic detergent supply device 1000. (40) can be installed.

The top cover 20 may be made of a material different from that of the cabinet 10.

Accordingly, although the cabinet 10 is made of a metal material to ensure durability, the top cover 20 can be made of a resin series or the like to have a complex structure or be provided to easily combine different components.

For example, the door 30 that opens and closes the opening may be rotatably coupled to the top cover 20.

The automatic detergent supply device 1000 stores a larger amount of detergent as its volume increases, thereby reducing the number of times the user recharges the detergent.

Meanwhile, the automatic detergent supply device 1000 may be detachably installed in the laundry treatment device 1 of the present invention. As a result, the automatic detergent supply device 1000 can be easily cleaned by the user, and can be easily replaced even if detergent or foreign substances that the user does not want are added.

Meanwhile, a suspension 40 is disposed at a corner of the cabinet 10, and the tub 50 is disposed adjacent to the inner top of the cabinet 10 in the height direction, so that the inside of the cabinet 10 There is not enough space for the automatic detergent supply device 1000 to be installed.

Therefore, the automatic detergent supply device 1000 can be placed outside the cabinet 10 and expanded to a sufficient volume without being restricted by the internal space of the cabinet 10.

The automatic detergent supply device 1000 may be coupled to the top cover 20 to be exposed to the outside. As a result, the automatic detergent supply device 1000 can be easily removed and installed on the top cover 20.

Meanwhile, when the automatic detergent supply device 1000 is disposed on the front or both sides of the door 30 or the opening, the automatic detergent supply device 1000 opens the door 30 or puts clothes into the opening. can interfere with

Accordingly, the automatic detergent supply device 1000 may be placed behind the door 30 or the opening. As a result, the user can open the door 30 or insert clothing into the opening without being disturbed by the automatic detergent supply device 1000. In addition, the automatic detergent supply device 1000 can support the open door 30, preventing the door 30 from opening excessively.

Meanwhile, since the driving unit 90 is disposed at the lower part of the tub 50, when the laundry treatment apparatus of the present invention vibrates, the top cover 20 may vibrate the most. Since the automatic detergent supply device 1000 can accommodate a large amount of detergent, its weight is large and its inertial force is also large. In this situation, when the automatic detergent supply device 1000 is detachably coupled to the upper part of the top cover 20, the vibration with the largest amplitude among the laundry treatment devices is transmitted to the automatic detergent supply device 1000, There may be a high possibility that the automatic detergent supply device 1000 may be randomly separated from the top cover 20.

Therefore, the automatic detergent supply device 1000 may be completely accommodated in the housing provided in the top cover and may be provided as a drawer type that is drawn out from one side of the housing.

However, if the automatic detergent supply device 1000 is provided as a drawer type while being coupled to the rear of the door 30 of the top cover 20, the direction in which the automatic detergent supply device 1000 is pulled out from the housing may correspond to any one of the top, side, and front surfaces.

Since the top load type washing machine is equipped with a height greater than the width to secure washing capacity, it is very difficult for the user to completely withdraw and insert the automatic detergent supply device in the upper direction from the housing of the top cover 20. Additionally, since the automatic detergent supply device is disposed at the rear of the door 30, it may be very difficult for a user to withdraw or insert the automatic detergent supply device into the upper part of the housing of the top cover 20.

In addition, it may be easier for the user to have the automatic detergent supply device be pulled out and inserted from the top cover 20 into the housing from the side, rather than being pulled out and inserted upward.

However, in order for the automatic detergent supply device to be fully withdrawn from the housing, a space is needed to be removed from the side as long as the automatic detergent supply device. Therefore, if the space where the clothing treatment device is placed is small and the length for the automatic detergent supply device to be drawn out is not secured, there is a problem in which the user cannot utilize the automatic detergent supply device itself.

In addition, the configuration in which the automatic detergent supply device is pulled out and inserted forward from the top cover 20 ensures that the length at which the automatic detergent supply device is pulled out can always be secured.

However, in order for the automatic detergent supply device to be coupled to the housing and communicate with the tub, it is essential to have a pump or hose on the back of the housing that faces the side where the automatic detergent supply device is inserted to communicate with the automatic detergent supply device. .

Therefore, since the automatic detergent supply device must be placed ahead of the pump or hose, additional space for installing the pump/or hose must be secured on the back of the door 30 and the inlet. As a result, it may not be possible to secure sufficient volume for the automatic detergent supply device. If the length in the insertion/withdrawal direction is extended sufficiently to secure the volume of the automatic detergent supply device, the area of the opening becomes narrow, making it difficult to take in and out of clothes, or the opening and door 30 are connected to the top cover. Because the arrangement is excessively biased toward the front in (20), clothing may be piled up only in the front of the drum (60). As a result, problems resulting from unbalance within the clothing treatment device may occur.

As a result, in a top load type washing machine such as the laundry treatment device of the present invention, it is preferable that the automatic detergent supply device 1000 is not provided as a drawer type.

Therefore, the automatic detergent supply device 1000 of the laundry treatment device of the present invention may be installed on the top of the top cover 20 and exposed to the outside.

As a result, the automatic detergent supply device 1000 of the laundry treatment device of the present invention is not limited in the direction in which it is mounted or separated from the top cover 20 and can secure a degree of freedom compared to the drawer type, and has sufficient height, width, and length. You can expand more than one.

However, since it is difficult for the laundry treatment device of the present invention to accommodate and support the automatic detergent supply device 1000, it may be additionally provided with a configuration capable of firmly fixing the automatic detergent supply device 1000. This will be described later.

Figure 2 shows the structure of the laundry treatment apparatus of the present invention with the door open.

The automatic detergent supply device 1000 may be disposed at the rear of the door 30 to support the open state of the door 30 when the door 30 is opened.

The door 30 and the top cover 20 on which the automatic detergent supply device 1000 is mounted may be coupled to the upper part of the cabinet 10.

The top cover 20 is provided with an opening 21, and the door 30 can be rotatably coupled to the top cover 20 to open and close the opening 21.

The top cover 20 may place the control panel 40 ahead of the opening 21. As a result, the user can easily access the control panel 40.

The control panel 40 may have a built-in control unit that receives commands to control the clothing processing device and performs an arbitrary clothing processing course.

The control panel 40 includes a power supply unit 41 that receives a power command for supplying power to the control unit, an input unit 44 that receives an arbitrary course that the control unit can process, and an external device that reports the status of the control unit. It may include one or more of a display unit 44 that displays a , and a performance unit 42 that receives a command to perform the selected course.

The top cover 20 may be equipped with a water supply unit that receives water and a manual supply device 100 that is in communication with the water supply unit and can store detergent.

The manual detergent supply device 100 is arranged to be withdrawable from the rear to the front of the inner peripheral surface of the opening 21, so that the flow path connected to the water supply unit can be shortened. However, this is only an example, and the manual detergent supply device 100 may be installed in any location and in any configuration as long as it can store and discharge detergent.

The automatic detergent supply device 1000 may be placed rearward of the opening 21. As a result, the automatic detergent supply device 1000 and the manual detergent supply device 100 can share the flow path through which detergent is discharged. In addition, if the automatic detergent supply device 1000 and the manual detergent supply device 100 have independent channels for discharging detergent, they can be centrally arranged to increase space utilization inside the top cover 20.

The automatic detergent supply device 1000 is provided to protrude from the upper surface of the top cover 20 and can store a larger amount of detergent than required for one course.

In addition, it is provided to support the door 30, preventing the door 30 from colliding with a wall disposed behind the automatic detergent supply device 1000.

Figure 3 shows one embodiment of the structure of the laundry treatment device of the present invention.

The laundry treatment device 1 of the present invention can be equipped to perform any washing course to remove foreign substances from clothes with water and detergent.

The laundry treatment device of the present invention includes a cabinet 10 forming the exterior, a tub 50 provided inside the cabinet 10 to store water, and a tub 50 rotatably provided to accommodate clothing. It may include a drum 60 and a driving unit 90 coupled to the tub 50 to rotate the drum 50.

The cabinet 10 may have an opening at the top through which clothes are put in, and the tub 50 and the drum 60 may also have an opening at the top that allows the clothes to be put in.

Additionally, the driving unit 90 may be fixed to the lower surface of the tub 50 and rotate the drum 60.

The laundry treatment apparatus of the present invention may further include a suspension 70 supporting the tub 50 inside the cabinet 10, and the suspension is located at the bottom of the tub 50 and the inside of the cabinet 10. It may be equipped with a damper and spring connecting the upper part.

The laundry treatment device of the present invention is provided at the rear of the cabinet 10 and communicates with an external water supply source to supply water to the tub 50, and a water supply unit 70 that communicates with the lower part of the tub 50. It may include a drain unit 80 that discharges water contained in the tub 50 to the outside of the cabinet 10 .

The laundry treatment apparatus of the present invention may be provided with a detergent supply unit that supplies detergent to the tub 50. The detergent supply unit may include one or more of the manual detergent supply device 100 and the automatic detergent supply device 1000.

The manual supply device 100 may be equipped to allow the user to directly add detergent. The manual supply device 100 is provided to communicate with the water supply unit 70 and the tub 50, and receives the water supplied from the water supply unit 70, so that all of the introduced detergent is stored in the tub 50. supplied. As a result, the manual supply device 100 is equipped to directly supply an appropriate amount of detergent to the user each time the course is performed.

The automatic detergent supply device 1000 may be equipped to store a large amount of detergent supplied to the tub 50. That is, the automatic detergent supply device 1000 may be configured to store detergent capable of performing the course multiple times at once and discharge an appropriate amount of detergent into the tub 50 each time the course is performed.

Unlike the manual detergent supply device 100, the automatic detergent supply device 1000 may be configured not to receive water from the water supply unit 70. That is, since the automatic detergent supply device 1000 does not receive water from the water supply unit 70, even if a large amount of detergent is stored, it prevents all of the detergent from being discharged with the water supplied to the water supply unit 70. It can be.

The downstream part of the automatic detergent supply device 1000 may be in communication with the water supply unit 70 or the tub 50, but the upstream part may not be in communication with the water supply unit 70.

The laundry treatment device of the present invention may be equipped with both the manual detergent supply device 100 and the automatic detergent supply device 1000, or may be provided with only one of them.

When both the manual detergent supply device 100 and the automatic detergent supply device 1000 are provided, the manual detergent supply device 100 and the automatic detergent supply device 1000 are provided so that their respective downstream parts communicate. The flow path structure can be simplified.

Figure 4 shows the detergent supply part of the laundry treatment device of the present invention.

The detergent supply unit 1000 of the laundry treatment apparatus of the present invention may be installed on the top cover 20.

The top cover 20 is made of a plastic material and can be easily molded into a structure on which the detergent supply unit 1000 can be seated.

The water supply unit 70 may be installed on the back of the top cover 20. The manual supply device 100 may be disposed at the rear lower part of the opening 21 penetrating the top cover 20.

The manual supply device 100 is provided to be withdrawn forward from the top cover 20 and can receive powdered detergent or liquid detergent. The manual supply device 100 may be provided to communicate with the water supply unit 70 to receive water and discharge the introduced detergent to the bottom.

Since the tub 50 inlet is disposed at the bottom of the opening 21, the detergent discharged from the manual supply device 100 can be directly delivered to the inside of the tub 50.

The manual feeding device 100 may be provided with a drawer 101 that is withdrawn and retracted forward from the opening 21. As a result, the detergent is drawn forward only when it is put in, and the rest is accommodated in the top cover 20, so that it does not prevent the clothes from being put in.

The automatic detergent supply device 1000 may be placed at the rear upper part of the top cover 20. The automatic detergent supply device 1000 may be placed above the water supply unit 70 and may be placed above the manual detergent supply device 100.

Accordingly, the detergent discharged from the automatic detergent supply device 1000 can be delivered to the water supply unit 70 or the manual detergent supply device 100 and supplied to the tub 50.

The automatic detergent supply device 1000 includes a detergent box 200 that stores detergent supplied to the tub 50, and a mounting part 300 that secures the detergent box 200 to the top of the top cover 20. may include.

The detergent box 200 may be detachably mounted on the mounting unit 300 . Accordingly, the detergent box 200 can be separated from the mounting unit 300 whenever necessary, making cleaning/maintenance easy.

Additionally, when a user supplies detergent to the detergent box 200, the detergent box 200 can be separated from the mounting unit 300. As a result, the user can put the detergent into the detergent box 200 without being restricted by location, and the top cover 20, etc., is prevented from being contaminated during the process of putting detergent into the detergent box 200. It can be.

The detergent box 200 may be provided in plural numbers to store different detergents. A plurality of the detergent boxes 200 may be mounted on the mounting unit 300 along the width direction of the top cover 20.

The mounting portion 300 may be disposed at the rear of the top cover 20 in the width direction. The mounting unit 300 may be provided integrally with the top cover 20, but may be mounted rearward of the door 30 on the upper surface of the top cover 20.

The mounting unit 300 may be provided so that the detergent box 200 is mounted on the upper part, and the detergent box 200 may be provided so that the lower part of the detergent box 200 is detachably fixed to the mounting unit 200 .

The detergent box 200 can be coupled to and separated from the mounting unit 300 while exposed to the outside of the top cover 20. As a result, the direction in which the detergent box 200 is coupled to or separated from the mounting unit 300 may not be fixed in a specific direction. As a result, the user can attach and separate the detergent box 200 from the mounting unit 300 without being significantly limited by the height of the cabinet 10.

The total length of the detergent box 200 may be longer than the height or thickness of the detergent box 200. As a result, the detergent storage capacity of the detergent box 200 can be increased while the center of gravity of the detergent box 200 can be lowered and the area of the door 30 or the opening 21 can be guaranteed.

The mounting unit 300 may be equipped with a transfer unit that receives the detergent from the detergent box 200 and discharges it into the tub 50. The transfer unit includes a detergent pump that discharges detergent from the detergent box (200), and a detergent pump that communicates the detergent pump to one or more of the water supply unit (70), the tub (50), and the manual detergent supply device (100). May include a supply pipe.

Figure 5 shows a structure in which the detergent box is attached and detachable from the mounting part.

Referring to Figure 5(a), the detergent box 200 includes a first detergent box 200a that stores the first detergent and is detachably coupled to the mounting unit 300; It may include a second detergent box 200b that is provided separately and stores the second detergent and is detachably coupled to the mounting unit 300.

The first detergent may be a laundry detergent needed to remove foreign substances from clothing, and the second detergent may be a bleaching agent that bleaches clothing or a softener that adjusts the hardness and scent of fibers.

The first detergent and the second detergent may be provided in liquid form. Accordingly, the first detergent and the second detergent can be easily discharged into the mounting unit 300 by their own weight.

The manual detergent supply device may be equipped to store a third detergent. The third detergent may be a different type of detergent from the first and second detergents, or may be the same detergent as the first and second detergents, but in powder form rather than liquid. .

Of course, the third detergent may be completely the same as either the first detergent or the second detergent.

The first detergent box 200a and the second detergent box 200b may be provided in the same shape, may be provided symmetrically with respect to opposing surfaces, or may be provided in completely different shapes.

However, the first detergent box 200a and the second detergent box 200b may have a structure that performs the same function, and may be detachably mounted on the mounting unit 300 in the same manner.

Below, the structure, coupling method, fixation method, and detection method of the detergent box 200 and the mounting unit 300 will be described based on the second detergent box 200b. However, this is only to avoid redundant explanation, and can be equally applied to the first detergent box 200a.

Referring to Figure 5(b), the detergent box 200 may include a storage body 210 that provides a space to store detergent.

The storage body 210 can be coupled to and separated from the mounting portion 300 by sliding in the width direction of the top cover 20.

The storage body 210 does not need to be lifted from the mounting part 300 when separated from the mounting part 300, and needs to be lifted to the top of the mounting part 300 when coupled to the mounting part 300. There is no Therefore, even if the storage body 210 is mounted on the top of the top cover 20 and at the rear of the top cover 20, the user can easily attach the storage body 210 to the mounting unit 300. It is detachable.

Additionally, the storage body 210 may be attached or detached from the mounting unit 300 by being pressed or pulled from the side of the mounting unit 300. Accordingly, even when the door 30 opens the opening 21, the user can attach and detach the storage body 210 from the mounting part 300 in a slide manner from behind the door 30 without being restricted. .

Referring to Figure 5(c), when the storage body 210 is separated by moving to the side from the mounting part 300, from then on, it can freely move not only to the side of the mounting part 300, but also to the top, front, rear, etc. You can.

In other words, even if the inner surface of the storage body 210 does not move to the outside of the mounting part 300, the storage body 210 can be completely separated from the mounting part 300. For example, when the storage body 210 and the mounting unit 300 are separated from the fluid communication state, the storage body 210 may be completely detachable from the mounting unit 300. Accordingly, the storage body 210 may continue to move to the side of the mounting part 300 while being supported on the mounting part 300, and may be lifted from the mounting part 300 in all directions except the bottom to move the mounting part 300. can be separated from

As a result, a wall or other home appliances, etc. are placed on the outer surface of the top cover 20 or the outer surface of the mounting part 300, creating a space for the storage body 210 to slide along the length of the storage body 210. Even if this is not secured, the storage body 210 can be separated from the mounting unit 300.

When the storage body 210 is coupled to the mounting unit 300, the above-described method can be performed in reverse order.

Referring to Figure 5(d), the mounting part 300 may include a communication part 370 that is detachably provided with the storage body 210. The storage body 210 may be detachably provided in the communication part 370 and may be provided to discharge the stored detergent into the communication part 370.

The communication part 370 may be provided to protrude from the mounting part 300 in the width direction of the top cover 20. As a result, the storage body 210 can move in the width direction of the top cover 20 and be coupled to the communication portion 370.

The mounting part 300 may be provided to slide and move on the upper part of the mounting part 300 until the storage body 210 is completely separated from the mounting part 300.

However, the storage body 210 can slide on the mounting part 300 only when coupled to the communicating part 370, and can slide on the mounting part 300 when the coupling with the communicating part 370 is released. It can be completely separated without moving.

As a result, the storage body 210 slides in the width direction of the top cover 20 from the upper part of the mounting part 300 and can be coupled to and separated from the mounting part 300. However, the storage body 210 may be supported on the upper part of the mounting part 300 and slide only when fluidly coupled to and separated from the mounting part 300. That is, when the storage body 210 is fluidly disconnected from the mounting part 300, the storage body 210 is free from the upper part of the mounting part 300 without being restricted by the shape of the mounting part 300. You can move.

The mounting portion 300 may include a mounting groove 310 that accommodates and supports at least a portion of the lower portion of the storage body 210.

The lower surface of the storage body 210, while accommodated in the mounting groove 310, may be supported on both sides of the mounting groove 310 and guided to slide.

A limiting surface 320 may be provided at one end or inside the mounting groove 310 to limit the inner movement or insertion of the storage body 210.

The limiting surface 320 supports the storage body 210 and can prevent the storage body 210 from vibrating inward.

The communicating portion 370 may be provided to protrude outward from the limiting surface 320. The communication portion 370 may be disposed closer to the bottom of the limiting surface 320 than to the top.

Meanwhile, when the detergent box 200 is seated on the mounting part 300, it needs to be prevented from being arbitrarily separated from the mounting part 300. The fact that the detergent box 200 slides along the mounting groove 310 and is easily attached to and detached from the mounting part 300 means that the detergent box 200 can be easily separated from the mounting part 300. Because it does.

Since the laundry treatment device of the present invention is equipped with a top load type washing machine, vibration of a larger amplitude is transmitted to the mounting unit 300. Accordingly, the mounting unit 300 can be easily coupled to the detergent box 200, but can be provided so that it is difficult to separate from the detergent box 200 and vibrate relatively.

To this end, the mounting unit 300 prevents the storage body 210 from being pulled out when the storage body 210 is coupled to the communication unit 370 or mounting on the mounting unit 300 is completed. (210) may further include a bump 330 that prevents sliding movement toward the outer surface.

The bump 330 may be provided to protrude from the other end or outside of the mounting groove 310.

The detailed structure of the mounting unit 300 supporting and fixing the detergent box 200 will be described later.

Figure 6 shows how the detergent box is attached and detached from the mounting portion based on the overall shape of the laundry treatment device.

Referring to Figure 6(a), the first detergent box 200a and the second detergent box 200b may be seated and fixed in an exposed state on the mounting part 300.

Since the opening 21 of the top cover 20 is disposed at the upper part of the cabinet, the first detergent box 200a and the second detergent box 200b may be placed in a structure in which they are received and pulled out in a drawer, etc. I can't. As a result, the lower portions of the first detergent box 200a and the second detergent box 200b are seated and fixed on the upper part of the mounting part 300, or are only partially received and seated on the upper part of the mounting part 300, The rest is fixed in an exposed state.

In order to maximize the volume of the first detergent box 200a and the second detergent box 200b while securing the area of the opening 21, the first detergent box 200a and the second detergent box 200b are installed. (200b) is provided with a length corresponding to the width direction of the top cover 20 that is longer than a thickness corresponding to the front-to-back direction of the top cover 20.

Accordingly, the first detergent box 200a and the second detergent box 200b are provided in a structure that is mounted on the mounting part 300 while sliding in the width direction, so that the detergent box 200 and the mounting part 300 ) can be stably combined and separated.

Referring to Figure 6(b), the first detergent box 200a and the second detergent box 200b slide from the center of the mounting part 300 toward the outside of the mounting part 300 while moving the mounting part ( 300).

The detergent box 200 can slide and move the mounting part 300 until it is separated from the mounting part 300. Accordingly, stability can be ensured when the detergent box 200 is mounted on or detached from the mounting unit 300.

The mounting unit 300 may support the first detergent box 200a with the first mounting area 310a, and support the second detergent box 200b with the second mounting area 310b. there is.

The first mounting area 310a forms a receiving space in the mounting portion 300 capable of accommodating at least a portion of the first detergent box 200a, and forms a first mounting area capable of supporting the first detergent box 200a. It may be provided with a mounting groove 310a, but may be provided in any configuration as long as it can support the first detergent box 200a.

The second mounting area 310b forms a receiving space in the mounting portion 300 that can accommodate at least a portion of the second detergent box 200b, thereby forming a second mounting area capable of supporting the second detergent box 200b. It may be provided with a mounting groove 310b, but may be provided in any configuration as long as it can support the second detergent box 200b.

The mounting portion 300 may be provided longer than the length DO of the mounting area 310. That is, the mounting portion 300 may further include an outer step 360 extending from the mounting area 310 toward the outer surface of the top cover 20.

When the detergent box 200 is coupled to the mounting area 310, the area from the outer end of the mounting area 310 to the inner surface of the outer step 360 does not directly support the detergent box 200. , Corresponds to the spare area exposed to the outside. That is, the mounting part 300 may further include an area corresponding to the spare length D2 outside the mounting area 310.

The length of the detergent box 200 may be provided to correspond to the length D0 of the mounting area 310. Accordingly, when the detergent box 200 is seated in the mounting area 310, it can be exposed to the outside as much as the spare length D2 of the mounting part 300.

As a result, even if the detergent box 200 slides completely out of the mounting part 310, it can be supported on the mounting part 300 by the extra length D2.

If the detergent box 200 is slidably moved by the length DO of the detergent box 200 in the mounting area 310, even if a part of the detergent box 200 can be supported in the spare length D2. , coupling to and separation from the mounting portion 300 can be completed.

Therefore, even if the detergent box 200 contains at least some detergent and is somewhat heavy, the user can slide and move the detergent box 200 while supporting the load of the detergent box 200 on the mounting part 300 as much as possible. As a result, the detergent box 200 can be easily separated from the mounting unit 300.

In addition, the user can slide-couple the detergent box 200 to the mounting area 310 while transmitting the load of the detergent box 200 to the mounting part 300 from the area corresponding to the spare length D2 of the mounting part 300. .

As a result, even if the detergent box 200 contacts only the lower part of the mounting part 300 and does not have a guide member such as a drawer that induces the slide movement, it can be stably coupled or separated while sliding to the mounting part 300. You can.

Figure 7 shows a situation in which it is difficult to separate the detergent box.

As described above, in the detergent box 200 of the present invention, the top cover 20 slides from the outside to the inside and is coupled to the mounting part 300, and slides from the inside to the outside of the top cover 20. It is separated from the mounting part 300.

However, even if the detergent box 200 does not slide along the entire area of the mounting area 310, it can be provided to be separated from or coupled to the mounting part 300.

If the detergent box 200 is provided to slide in one direction from beginning to end to be coupled to the mounting area 310, the detergent box 200 can be stably coupled to and separated from the mounting portion 300. There is. However, in some cases, it may be impossible to attach the detergent box 200 to the mounting unit 300 or to separate it from the mounting unit 300.

Referring to Figure 7(a), a home appliance such as a refrigerator 2 may be placed close to one side of the laundry treatment device 1 of the present invention. Since the second detergent box 200b can slide in the mounting area 310 beyond the length DO of the second detergent box 200b, it can easily be forcibly coupled to or separated from the mounting area 310. You can.

However, the distance between the first detergent box 200a and the refrigerator 2 may be shorter than the length D0 of the first detergent box 200a. Therefore, the first detergent box 200a may not be able to slide in the mounting area 310 by the length DO of the first detergent box 200a.

Additionally, if the first detergent box 200a is completely separated from the mounting area 310, the first detergent box 200a may not be able to be inserted into the mounting area 310.

Therefore, if the detergent box 200 cannot slide on the mounting area 310 by the length D0 of the detergent box 200, the detergent box 200 is separated from the mounting area 310. It may be impossible to become or combine.

Referring to Figure 7(b), even if there is no home appliance 2 adjacent to the laundry treatment device 1 of the present invention, it can be placed in a narrow space such as a laundry room or utility room.

For example, the laundry treatment device 1 of the present invention may be placed in a multi-purpose room, etc., where the distance from the wall w is narrower than the length DO of the detergent box 200.

In this case, it is impossible for both the first detergent box 200a and the second detergent box 200b to slide in the mounting area 310 by the length DO of each detergent box 200.

As a result, the first detergent box 200a and the second detergent box 200b may be prevented from being separated or combined in the mounting area 310.

As a result, in the laundry treatment apparatus of the present invention, when the detergent box 200 is coupled to or separated from the mounting part 300, if the detergent box 200 is forced to slide by the length DO, the automatic detergent The effectiveness of the supply device 1000 may be reduced by half.

Therefore, the laundry treatment device of the present invention can be provided to be coupled to or detachable from the mounting unit 300 even if the detergent box 200 slides shorter than the length DO of the detergent box 200.

Figure 8 shows another embodiment in which the detergent box of the present invention can be combined or separated from the mounting unit.

Referring to Figure 8(a), the first detergent box 200a and the second detergent box 200b may be mounted on the mounting unit 300.

Referring to Figure 8(b), at least one detergent box 200 of the first detergent box 200a and the second detergent box 200b has a length of the mounting part 300 in the mounting part 300. It can be slid in either direction or in the width direction of the top cover 20.

Referring to Figure 8(c), when the detergent box 200 is separated from the communication part 370 by sliding on the mounting part 300, the detergent box 200 is separated from the mounting part 300. It may be slidably moved in the longitudinal direction of 300 or in the width direction of the top cover 20, but may also be lifted straight upward.

Referring to Figure 8(d), the storage body 210 of the detergent box 200 can be completely separated from the firewood area 310 even without leaving the mounting part 300 at all.

The process of coupling the detergent box 200 to the mounting unit 300 can be completed by performing the above-described process in reverse order.

As a result, even if the detergent box 200 of the present invention slides in the mounting part 300 to a length shorter than the length DO of the detergent box 200, the detergent box 200 of the present invention can be completely coupled to or separated from the mounting part 300. It can be provided.

In addition, the detergent box 200 may be provided so that it can be completely coupled to or separated from the mounting unit 300 even if it slides only within both ends of the mounting unit 300 without being exposed to the outside. there is.

As a result, home appliances 2 or walls (W), etc. are provided on the outer surface of the mounting part 300 or the top cover 20, so that the detergent box 200 is mounted on the outside of the mounting part 300 or the top cover 20. Even if space to slide is not secured, the detergent box 200 may not be restricted from being attached to or separated from the mounting unit 300.

Figure 9 shows in detail the process of attaching or detaching the detergent box from the mounting unit.

Referring to FIG. 9(a), the detergent box 200 includes a storage body 210 that stores the detergent, and is coupled to the storage body 210 or disposed below the storage body 210 and is connected to the mounting unit. It may include a plate 220 supported on 300, and a discharge part 230 installed on the plate 220 to communicate with the mounting part 300 and discharging detergent to the outside of the storage body 210. there is.

The storage body 210 may include a receiving body 211 disposed inside the mounting groove 310. The storage body 210 may further include an installation portion 212 disposed outside the mounting groove 310 to secure the storage body 210.

A fixing part 400 may be provided inside the installation part 212 to fix the storage body 210 to the mounting groove 310, and the detergent box 200 may be installed in the fixing part 400. A detection unit 500 that can notify that it is coupled to the mounting unit 300 may be installed.

A partition plate 225 may be disposed between the installation part 212 and the receiving body 211 to separate each area. The installation part 212 may be provided with a coupling part 250 that couples the exterior of the mounting groove 310 to the detergent box 200.

Meanwhile, the mounting unit 300 may be provided with a communication unit 370 that is detachably coupled to the discharge unit 230. The communication part 370 can receive the detergent stored in the receiving body 211 and transfer it to a detergent pump disposed inside the top cover 20 and discharging the detergent into the tub 20.

Meanwhile, the receiving body 211 may be disposed rearward of the communicating portion 370 at a distance equal to or further apart from the coupling length D4 (described later) and supported on the mounting portion 300. The mounting portion 300 may be provided to support the lower surface of the receiving body 211 disposed rearward than the communicating portion 370 by disposing a support surface 380 between the mounting grooves 310.

The total length of the receiving body 211 may be set to be longer than the total length of the mounting groove 310. As a result, the load of the detergent box 200 is distributed to the outside of the mounting groove 310 so that the detergent box 200 can be stably supported on the mounting part 300.

Meanwhile, the discharge part 230 can be provided to be coupled to the communication part 370 only when it moves from the free end of the communication part 370 to the fixed end of the communication part 370 by the coupling length D4. there is.

When the discharge part 230 is coupled to the communicating part 370, it must move by the coupling length D4 to be separated from the communicating part 370.

The communication part 370 may be arranged to face the direction in which the detergent box 200 is slid and introduced, and the discharge part 230 can be slidably moved to the mounting part 300 among the detergent box 200. It can be placed in a position where it can face the communication part 370.

Referring to Figure 9(b), the detergent box 200 can be moved out of the mounting unit 300 by the length D4 or more. The spare length D2 disposed outside the mounting groove 310 may be formed to be equal to or longer than the coupling length D4. Therefore, even if the detergent box 200 slides outward from the mounting groove 310 by the engagement length D4, the end of the detergent box 200 extends further outward than the outer surface of the top cover 20. It may not protrude. Additionally, if the end of the detergent box 200 is arranged parallel to the outer surface of the top cover 20, the discharge part 230 can be completely separated from the communication part 370.

Referring to Figure 9(C), if the discharge part 230 is separated from the communication part 370, the mounting part 300 may be unable to fix the detergent box 200. From this point on, the detergent box 200 may continue to slide from the mounting unit 300 toward the outer surface of the top cover 20, or may be lifted upward from the mounting unit 300.

In addition, in a state in which the discharge portion 230 is coupled to the communication portion 370, even if the detergent box 200 slides to a length shorter than the coupling length D4, the detergent box 200 When the end is lifted upward and rotated, the discharge part 230 can move in the communication part 370 beyond the combined length D4, and the discharge part 230 and the communication part 370 are separated. It can be.

As a result, if the discharge part 230 can be separated from the communication part 370, the detergent box 200 can slide the mounting part 300 in the width direction of the top cover 20, The end of the detergent box 200 may be lifted upward and the detergent box 200 may rotate based on the communication part 370.

Referring to Figure 9(d), the detergent box 200 can be completely separated from the mounting unit 300.

When the detergent box 200 is provided in plural and arranged side by side in the width direction of the top cover 200, the detergent box 200 slides the outside of the top cover 200 only by the coupling length D4. When moved, the detergent box 200 can be separated from the mounting unit 300. In addition, even if the detergent box 200 slides and moves less than the coupling length D4, the end of the detergent box 200 disposed adjacent to the outside of the top cover 200 is lifted and the detergent box ( If 200 can rotate, the detergent box 200 can be separated from the mounting part 300.

Additionally, the process of coupling the detergent box 200 to the mounting unit 300 can be performed by reversing the above process.

Therefore, the detergent box 200 is installed regardless of the space in which the laundry treatment device 1 is placed. The coupling and separation can be completed by sliding the top cover 20 in the width direction of the mounting portion 300.

Figure 10 shows the detailed structure of the mounting portion 300.

The mounting portion 300 includes a mounting body 301 disposed in the width direction of the top cover 20 at the top of the top cover 20 and supporting the detergent box 200, and a mounting body 301 in the mounting body 301.

By pushing (260) out of the support body (210), the push part (260) can be placed in the correct position.

Figure 20 shows an example of the detailed structure of the fixing part.

Figure 20(a) shows a perspective view of the fixing part 400, and Figure 20(b) shows a side view of the fixing part 400.

The fixed body 410 may be accommodated in the guide pillar 2241 and be provided to reciprocate up and down. The fixing body 410 may be provided in the shape of a long bar.

The fixing body 410 may include a lower locking portion 411 provided at the bottom and supported by the bump 330.

A detection unit 500, which will be described later, may be installed in the lower locking part 411.

The fixing body 410 may include a moving groove 412 pressed by the push part 260 above the lower locking part. The moving groove 412 has a parallel surface 4122 disposed parallel to the insertion direction of the push part 260, and an inclined surface extending obliquely upward from the inside of the parallel surface 4122 toward the push part 260 ( 4121).

The fixing body 410 may be provided with a restoration seating part 414 on which the restoration part 420 can be seated. The restoration seating part 414 may be provided with a protrusion that protrudes from the upper part of the fixing body 410 and can be coupled to the lower end of the restoration part 420.

The restoration part 420 may include a spring accommodated inside the guide pillar 2241 and seated on the restoration seating part 414.

The fixing body 410 may include an prevention rib 413 protruding from one side.

The prevention rib 413 may be seated in a locking groove provided along the height direction of the guide pillar 2241. The prevention rib 413 is slidably moved in a locking groove provided on the guide pillar 2241, and guides the fixing body 410 to move up and down in the forward direction, and the fixing body 410 is connected to the guide pillar ( 2241) It can be prevented from escaping to the outside.

The prevention ribs 413 may protrude from both sides of the fixed body 410 and may be provided to protrude from a lower portion of the moving groove 412.

The fixed body 410 may have a detection unit 500 installed therein, which will be described later. The detection unit 500 may include a generator 510 that generates a signal or magnetic force, and a sensor unit 520 that detects the generator 510. At this time, the generator 510 may be installed inside the fixed body 410.

The fixed body 410 may include a sensing receiver 415 that provides a space for accommodating the generator 510, and the sensing receiver 415 is provided on one side of the fixed body 410. It can be provided with a groove that can accommodate the generator 510.

The fixing body 410 may further include a prevention rib 416 that prevents the generating part 510 from leaving the sensing receiving part 415. The prevention rib 415 may be provided to shield a portion of the opening of the sensing receiver 415.

The position of the generator 510 can be changed or vibration can be prevented.

Figure 21 shows a structure in which the push part elevates the fixing part.

The push part 260 includes a push body 261 coupled to one side of the storage body 210 and exposed to the outside, and a moving groove of the fixing part 420 extending from the inside of the push body 261 ( It may include an insertion protrusion 263 extending to 412).

The push body 261 is provided to be pressed into the storage body 210 by an external force, and the insertion protrusion 263 penetrates the insertion hole 2133 in the push body 261 to form the moving groove ( 412).

When the insertion hole 2133 is disposed to be biased to one side in the seating groove 2131, the insertion protrusion 263 may also protrude from the push body 261 to one side.

The free end of the insertion protrusion 263 may be provided in a shape corresponding to the inclined surface provided in the moving groove 412.

The free end of the insertion protrusion 263 may be inclined toward the top. That is, the length of the lower surface of the insertion protrusion 263 may be longer than the length of the upper surface of the insertion protrusion 263.

Referring to Figure 21(a), when the push body 261 is pressed, the insertion protrusion 263 begins to push the moving groove 412 and moves to the lower part of the moving groove 412. Since the height of the insertion protrusion 263 is always maintained, the fixing body 410 moves upward and the restoration part 420 is pressed.

As a result, the lower locking portion 411 moves upward and can be accommodated inside the storage body 210.

Referring to Figure 21 (b), the fixing installation part 224 includes a guide pillar 2241 that supports the fixing part 400 to guide it in the vertical direction, and penetrates the side of the guide pillar 2241 to It may include an input hole 2242 through which the push unit 260 passes.

The guide pillar 2241 may be provided in a duct shape through which the fixing part 400 can move back and forth. The guide pillar 2241 may be provided with a discharge hole 2245 that penetrates the plate 220 and guides the lower locking portion 411 to be pulled out. The discharge hole 2245 may form an opening of the guide pillar 2241.

The fixing installation part 224 may further include a fixing pillar 2244 provided inside the guide pillar 24241 to face the discharge hole 2245 and fixing the restoration part 420.

When the external force pressing the push body 261 is released, the restoration part 420 begins to expand and the fixing body 410 can be moved downward. The moving groove 412 moves downward and pushes the insertion protrusion 263 in a direction toward the push body 261.

As a result, the lower locking portion 411 may move downward and protrude out of the storage body 210.

Figure 22 shows an embodiment in which the detergent box is separated from the mounting unit.

Referring to Figure 22(a), the detergent box 200 is mounted on the mounting unit 300. In addition, in the detergent box 200, the outer area including the installation part 212 is placed in a state of being seated on the upper part of the bump 330.

However, the fixing part 400 also protrudes from the installation part 212 at its lower part and is supported on the inner surface of the bump 330.

As a result, part of the lower surface 222 of the detergent box 200 is accommodated in the mounting groove 310, and the remaining portion is disposed outside the mounting groove 310 beyond the bump 330. Even so, the detergent box 200 can remain mounted on the mounting unit 300.

In addition, even if vibration in the width direction occurs in the detergent box 200 or a force is applied to pull the detergent box 200 to the outside of the mounting body 301, the detergent box 200 moves outward. It can be fixed to the mounting part 300 without doing so.

Referring to Figure 22(b), when the push part 260 is pressed, the fixing part 400 may rise upward.

When the fixing part 400 rises, the fixing part 400 is accommodated inside the storage body 210, and any configuration of the detergent box 200 is not restricted by the bump 330.

Of course, if vibration is not transmitted to the detergent box 200 or there is no outward pulling force, since the discharge part 230 and the communication part 370 are coupled, the detergent box 200 is not connected to the mounting part. The mounted state at 300 may be maintained.

If the external force applied to the push unit 260 is released again and the fixing unit 400 descends, the detergent box 200 may be fixed to the mounting unit 300.

Referring to Figure 22(c), when the push part 260 is pressed and the fixing part 400 rises higher than the upper surface of the bump 330, the lower part of the detergent box 200 is pressed against the bump 330. It is only seated on the top of 330, and the bump 330 no longer secures the detergent box 200.

Of course, when vibration is applied to the detergent box 200 or the detergent box 200 is pulled outward, the coupling force of the coupling portion 250 and the fastening portion 334, the discharge portion 230 and the Due to the coupling force of the communication part 370, the detergent box 200 can be maintained fixed to the mounting part 300.

However, when the detergent box 200 is pulled with a force stronger than the coupling force between the coupling portion 250 and the fastening portion 334 and the coupling force between the discharge portion 230 and the communication portion 370, the The detergent box 200 may slide outward from the mounting groove 310.

The process of sliding the detergent box 200 from the outside to the inside of the mounting unit 300 is the same as the reverse of the above-described process.

Accordingly, even if the automatic detergent supply device 1000 is not accommodated in a drawer, etc., it can be stably supported due to the structure of the fixing part 400 and the bump 330. In addition, due to the structure in which the fixing part 400 is selectively supported by the bump 330, the automatic detergent supply device 1000 can be easily separated from the top cover 20 when the user wishes to separate it. You can.

Figure 23 shows a structure for detecting that the detergent box is mounted on the mounting unit.

Since the automatic detergent supply device 1000 of the laundry treatment device of the present invention is mounted on the top cover 20 by sliding the top cover 20, the coupling force is weaker than that provided as a drawer type. In addition, since the automatic detergent supply device 1000 is provided to slide from the side, the coupling force is weaker than when the automatic detergent supply device 1000 is slidably coupled in the vertical direction.

In other words, since the detergent box 200 slides to the side and is coupled to the mounting part 300, even if the mounting part 300 fixes the detergent box 200, the detergent box 200 can be moved to the side arbitrarily. There is a possibility that it may move and be separated from the mounting portion 300.

Accordingly, the laundry treatment apparatus of the present invention may further include a detection unit 500 that detects whether the detergent box 200 is coupled to the mounting unit 300.

When the laundry treatment device of the present invention detects that the detergent box 200 has been separated from the mounting unit 300, it can notify the user through the control panel 40.

In addition, when it is detected that the detergent box 200 begins to separate from the mounting part 300 during the wash cycle, the washing course is stopped and the detergent box 200 is completely separated from the mounting part 300. It can be prevented.

The detection unit 500 may be provided in the mounting unit 300 to detect whether the detergent box 200 is mounted by directly contacting the detergent box 200.

The contact sensing unit 500 may be provided on the limiting surface 320.

The contact sensing unit 500 must be provided to be pressed together when the detergent box 200 is mounted on the mounting part 300 while sliding to detect positive engagement of the mounting part 300 of the detergent box 200. can do.

However, since the mounting groove 310 is provided to support only a portion of the lower part of the detergent box 200, its depth is not deep. Accordingly, since the height of the limiting surface 320 is not large, the contact sensing unit 500 has no choice but to be placed adjacent to the discharge unit 370.

As a result, when detergent from the detergent box 200 leaks into the mounting groove 310 or water discharged from clothes, etc. is collected into the mounting groove 310, the contact sensing unit 500 detects the detergent or water. Reliability cannot be guaranteed as it is exposed to water.

In particular, even if the contact sensing unit 500 is sealed at the limiting surface 220, since the contact sensing unit 500 must be reciprocated and pressurized or come into contact with a surface, it will not be reliable if water and detergent come into contact with it. It is difficult to guarantee.

Meanwhile, if the contact sensing unit 500 is placed in a different area beyond the limiting surface 320 and the mounting groove 310, it is difficult to arrange it to face the direction in which the detergent box 200 slides.

In this case, if the contact sensing unit 500 is placed far away from the discharge unit 370, such as a bump 330, even though the detergent box 200 is not coupled to the discharge unit 370, There is a high possibility that the contact sensing unit 500 will recognize that the detergent box 200 is fixed to the mounting unit 300 by being pressed against another configuration.

In addition, when the contact sensing unit 500 is disposed toward the upper surface of the mounting body 301, the movement of the detergent box 200 is restricted or friction caused by the detergent box 200 occurs. do.

Therefore, in a method such as the automatic detergent supply device 1000 of the present invention that slides and moves inward from both sides and is coupled, it is preferable that the sensing unit 500 is provided in a non-contact manner.

To this end, the sensing unit 500 may be provided in either the detergent box 200 or the mounting unit 300.

When the detection unit 500 is provided as a non-contact type, the detection unit 500 is provided in the mounting unit 300 and is equipped with light, radio waves including infrared rays, ultrasonic sensors, etc. to recognize the detergent box 200. It can be. However, the detection unit 500 that detects whether the detergent box 200 is installed using light, radio waves including infrared rays, ultrasonic waves, etc. may also be vulnerable to detergent and water.

Therefore, in order to effectively detect the installation of the detergent box 200 without being affected by water and detergent, the laundry treatment device of the present invention includes the detection unit 500 with a generator 510 that generates magnetic force or a signal, and , it can be provided with a sensor unit 520 that can detect the generator 510.

The sensor unit 520 may be provided to detect the position and separation distance of the generator 510 by detecting the strength of the magnetic force or signal generated from the generator 510.

For example, the generator 510 may be provided with a permanent magnet, and the sensor unit 520 may be provided with a Hall sensor that detects the permanent magnet.

Since the sensor unit 520 must continuously receive current or be connected to the control unit of the laundry treatment device, the sensor unit 520 is provided in the mounting unit 300, and the generating unit 510 is a detergent box ( 200).

Meanwhile, the detection unit 500 determines whether the first detergent box 200a and the second detergent box 200b are coupled to the first mounting groove 310a and the second mounting groove 310b, respectively. So it needs to be detected.

Therefore, the sensor unit 520 includes a first sensor unit 520a that detects that the first detergent box 200a is mounted in the first mounting groove 310a, and a second detergent box 200b. ) may include a second sensor unit 520b that detects that the sensor is mounted on the second mounting groove 310a.

The generator 510 is provided in the first detergent compartment 200a and stimulates the first sensor unit 520a, and is provided in the second detergent compartment 200b to stimulate the first sensor unit 520a. It may include a second generator (510b) that stimulates the second sensor unit (520b).

Meanwhile, the first sensor unit 520a and the second sensor unit 520b may be disposed on the discharge unit 370 or the limiting surface 320. However, in the mounting body 301, the limiting surface 320 and the discharge portion 370 are located at the center of the mounting body 301. In other words, since the detergent box 200 is comprised of the first detergent box 200a and the second detergent box 200b, they move inward from both sides of the mounting body 301 and are coupled to each other to get closer to each other. The bumps 330 are respectively disposed on both sides of the mounting body 301, and the limiting surface 320 and the discharge portion 370 are disposed in the middle of the mounting body 301.

The mounting groove 310 also has a first mounting groove 310a that is recessed on one side of the mounting body 301, and is spaced apart from the first mounting groove 310a in the width direction and is recessed in the mounting body 301. It may include a second mounting groove 310b, and a support surface 380 and a limiting surface 320 are disposed between the first mounting groove 310a and the second mounting groove 310b.

At this time, the first sensor unit 520a and the second sensor unit 520b are disposed on the support surface 380 and the limit surface 320, and the support surface 380 and the detergent box 200 are disposed on the support surface 380 and the limit surface 320. When the generator 510 is disposed adjacent to the limiting surface 320, the first sensor portion 520a and the second sensor portion 520b can detect all detergents even if only one generator 510 approaches. It may be mistakenly sensed that the ship 200 is installed.

In other words, the generator 510 provided in either the first detergent box or the second detergent box stimulates both the sensor parts 520 for detecting the first detergent box and the second detergent box, respectively. Therefore, it may be difficult to trust the state detected by the sensor unit 520.

Therefore, the farther away the generator unit 510 and the sensor unit 520, which are provided in the first detergent box and the second detergent box, respectively, are arranged, the more advantageous it is to secure the performance of the detection unit 500.

Therefore, the laundry treatment device of the present invention can install each sensor unit 520 closer to the bump 330 than the limiting surface 320, and the detergent box ( When the 200 is mounted on the mounting unit 300, the generator 510 can be installed at a location where it can face the sensor unit 520.

When the detergent box 200 is mounted on the mounting part 300 and the discharge part 230 is completely coupled to the communication part 370, the fixing part 400 is attached to the upper part of the bump 330. It may be provided to deviate from the surface, protrude from the detergent box 210, and be supported on the inner surface of the bump 330.

Referring to Figure 23, the generator unit 510 is installed on the fixing unit 400, and the sensor unit 520 is disposed adjacent to the bump 330 inside or below the mounting groove 310. When this happens, the detection unit 500 can detect the state in which the detergent box 200 is mounted on the mounting unit 300 and is fully coupled.

In other words, even if the detergent box 200 is mounted on the mounting unit 300, if it is not completely coupled, the detection unit 500 may determine that the detergent box 200 is not mounted on the mounting unit 300. . As a result, it is possible to ensure that the detergent box 200 is coupled to the mounting unit 300 in the correct position.

Meanwhile, when the push unit 260 is joined, even if the detergent box 200 is coupled to the mounting unit 300 in the correct position, the sensor unit 520 detects a change in the position of the generator 510. can be detected.

Accordingly, the sensor unit 520 can even detect the user's intention to separate the detergent box 200 from the mounting unit 300.

The present invention can be modified and implemented in various forms, but its scope is not limited to the above-described embodiments. Therefore, if the modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
