Description

Drawer and clothes treating machine including the same

The present invention relates to a drawer and a clothing treatment apparatus including the same, and more specifically, a drawer having a structure capable of preventing leakage of a clothing treatment agent that may occur when a storage container for automatically supplying a clothing treatment agent is detached. And it relates to a laundry treatment apparatus comprising the same.

The clothing treatment device is a device capable of washing, rinsing, dehydrating or drying clothing using natural or chemical substances such as detergents or softeners. The user may store the clothing to be treated in the clothing processing device and supply a detergent or a softener to process the clothing.

It is a cumbersome operation to supply an appropriate amount of a detergent or a softener to the clothes treatment apparatus each time the clothes treatment process is performed. Frequent opening and closing of drawers supplied with detergents or softeners may cause drawers to fail.

Accordingly, in recent years, technologies capable of performing a laundry treatment process several times by supplying a detergent or a softener once have been applied to a clothes treatment apparatus.

Specifically, the user may supply a detergent or a softener in advance to a storage container separately provided in the clothing treatment apparatus. At this time, a sufficient amount of detergent or softener is supplied to the storage container to perform several times of processing clothes.

When the user operates the clothing treatment device, the detergent or softener may be supplied to the tub in a required amount according to a set clothing treatment process. Accordingly, since the user does not need to supply a detergent or a softener every time the clothing treatment process is performed, the user's convenience may be increased.

An opening for receiving a detergent or a softener is formed in the storage container. Through the opening, the user can supply detergent or softener without removing the storage container from the drawer.

Depending on the state of use of the laundry treatment apparatus, there are cases where the storage container must be removed from the drawer. At this time, a situation in which the storage container is removed such that the portion in which the opening is formed is positioned at the lower side may occur due to the user's inexperience in operation.

In this case, there is a fear that the detergent or softener supplied to the storage container through the opening may be discharged to the outside. This situation can also occur when the storage container is accommodated in the drawer.

This is due to the fact that traditional drawers are not provided with a member for limiting the direction of insertion and removal of the storage container.

Korean Patent Document No. 10-0781247 discloses an automatic liquid detergent injection device for a washing machine. Specifically, it is inserted through the upper side of the washing machine, discloses a dispensing device having a structure capable of automatically injecting a liquid detergent.

However, this type of input device has a limitation in that a structural change of the washing machine is required in order to be coupled to the washing machine. Moreover, the above-described prior literature should be provided separately from the existing detergent supply unit. Accordingly, the structure of the washing machine is complicated, and since the user must supply detergent through a plurality of paths, there is a limitation in that it is difficult to increase the user's convenience.

Korean Patent Publication No. 10-2016-0087823 discloses a washing machine and a method for automatic detergent injection. Specifically, it discloses a washing machine and method for automatic detergent injection having a structure in which a detergent container is provided in an independent sealed cartridge structure and can be automatically supplied.

However, this type of washing machine and method for automatic detergent injection is applicable only when the detergent container is provided in an independent sealed cartridge structure. That is, there is a limitation in that it is difficult to apply to washing machines that are supplied with detergent through a drawer structure that is widely used recently.

Furthermore, the above-described prior literature has a limitation in that there is no consideration of a method for preventing the detergent contained in the detergent from being randomly leaked to the outside when the detergent container is separated.

According to the present invention, the following effects can be achieved.

First, a check valve and a sensor unit protrude from the rear side of the storage container. The check valve and the sensor unit are inserted into the rear end formed on the rear side of the drawer. The rear end includes an opening through which the check valve and the sensor unit are inserted and passed, and a partition member for partitioning the opening in a left-right direction. The partition member is configured to block communication between each partitioned opening.

Thus, when the storage container is inserted into the drawer, the check valve or sensor portion is caught in the partition member. Accordingly, either the check valve or the sensor unit must first be inserted into the opening. Similarly, even when the storage container is removed from the drawer, either the check valve or the sensor part must first be discharged from the opening.

As a result, in order to insert the storage container according to the above sequence, the rear side of the storage container must be inserted first and then the front side. Similarly, in order for the storage container to be removed according to the above sequence, the front side of the storage container must be removed first and then the rear side.

Accordingly, the order in which the storage container is inserted into the drawer and the order in which the storage container is removed from the drawer may be limited to the above order.

Further, the rear end is formed on the rear side of the drawer frame. The rear end is provided with an opening and a partition member for partitioning the opening upward and downward. With the above configuration, the storage container can be inserted and removed in the above-described order.

Accordingly, the order of insertion and removal of the storage container may be limited as described above, without excessively changing the structure of the drawer and the drawer frame.

In addition, when the storage container is inserted into the drawer according to the above-described sequence, the front side of the storage container is positioned above the rear side during the insertion process. Further, even when the storage container is removed from the drawer according to the above-described sequence, the front side of the storage container is positioned above the rear side in the removal process.

Accordingly, the clothing treatment agent accommodated in the storage container may not leak through an opening or a through hole formed in the front side of the storage container.

In addition, in order to prevent the valve or sensor unit from being caught on the partition member, the user must insert or remove the storage container according to the above direction and sequence. That is, the user can naturally recognize and learn the order and direction of the insertion and removal of the storage container in the process of inserting and removing the storage container.

Therefore, the user can easily recognize the order and direction of insertion and removal of the storage container without a separate guide phrase or label.

Further, a through hole is formed through the front side of the storage container. The through hole is configured to communicate the interior space and the exterior of the storage container.

Accordingly, even if the amount of the clothing treatment agent stored in the storage container is reduced, the pressure in the internal space of the storage container is equal to the outside, for example, atmospheric pressure due to the through hole. As a result, the clothing treatment agent stored in the storage container can be smoothly supplied to the tub.

In addition, in an embodiment, the rear side of the dispenser assembly into which the drawer is inserted may be supported by a support member. The support member is coupled through the rear surface of the housing. The dispenser assembly is insertedly coupled to the support member.

Therefore, compared to the case where the dispenser assembly is supported only by the housing frame, stable support is possible. Accordingly, even when vibration is generated as the laundry treatment apparatus is operated, the dispenser assembly can be stably maintained in its original position.

In addition, in one embodiment, the clothing treatment agent housing is spaced apart from the housing receiving unit by a predetermined distance and accommodated in the housing receiving unit. When the clothing treatment agent or fluid is excessively injected into the clothing treatment agent housing and overflows, the overflowing clothing treatment agent or fluid may be discharged through the space formed by the separation.

Accordingly, the overflowing clothing treatment agent or fluid does not come into contact with the storage container or remain in the space inside the drawer. In addition, since the overflowing clothing treatment agent or fluid is supplied to the tub through the space, the amount of waste treatment agent or fluid may be reduced.

In addition, in one embodiment, a discharge inclined portion is formed on the lower side of the storage container. The discharge inclined portion is formed to be inclined toward the rear side. A collection space is formed on the rearmost side of the discharge inclined portion, and the clothing treatment agent flowing to the rear side is collected.

A check valve is partially accommodated in the discharge slope. The discharge slope and the inner space of the check valve communicate with each other. The collected clothing treatment agent may be supplied to the tub through a check valve.

Therefore, the amount of the clothing treatment agent remaining in the storage container can be minimized. Accordingly, contamination by the remaining clothing treatment agent can be prevented. Furthermore, in order to compensate for the residual amount of the clothing treatment agent, it is not necessary to frequently supply the clothing treatment agent to the storage container.

On the storage lids 412 and 422, through holes 415 and 425 are formed through the front sides of the storage caps 414 and 424. The through holes 415 and 425 are configured to communicate inside and outside the storage body parts 411 and 421 to maintain an equilibrium of pressure inside the storage body parts 411 and 421.

Specifically, when the clothing treatment agent accommodated in the storage body parts 411 and 421 is discharged through the clothing treatment agent pump unit 220, a negative pressure is formed inside the storage body parts 411 and 421.

Therefore, when it is desired to discharge the clothing treatment agent for the next clothing treatment process, the discharge process is difficult to proceed smoothly. In addition, when the user wants to open the storage caps 414 and 424 to additionally supply the clothing treatment agent, it is difficult to remove the storage caps 414 and 424 due to the pressure inside the storage body parts 411 and 421. I can lose.

Accordingly, the through holes 415 and 425 communicate inside and outside the storage body parts 411 and 421, so that the pressure inside the storage body parts 411 and 421 and the atmospheric pressure can be balanced. Accordingly, the pressure inside the storage body portions 411 and 421 may be maintained equal to the atmospheric pressure despite the outflow of the clothing treatment agent.

The rearward movement of the check valve closure portions 416b and 426b is achieved by the elastic restoring force stored in the check valve elastic portions 416c and 426c.

The check valve elastic parts 416c and 426c are compressed in accordance with the forward movement of the check valve closure parts 416b and 426b to store the elastic restoring force. The check valve closure portions 416b and 426b are moved rearward by a predetermined distance by the stored elastic restoring force. Accordingly, the opening formed on the rear side of the check valve cylinder portions 416a and 426a can be closed.

When the check valve stoppers 416b and 426b are moved by a predetermined distance to the front side by the primary pump valve 224, the check valve elastic parts 416c and 426c are compressed. In the above state, the storage containers 410 and 420 accommodated in the drawer 300 are combined with the clothing treatment agent pump unit 220.

When the coupling state of the storage containers 410 and 420 and the clothing treatment agent pump unit 220 is released, that is, when the drawer 300 is discharged from the dispenser assembly 200, the check valve elastic portions 416c and 426c are in their original shape. Is returned to In this process, the check valve plug portions 416b and 426b are moved to the rear side by the stored elastic restoring force, thereby closing the rear openings of the check valve cylinder portions 416a and 426a.
