The detergent may be classified into a powder detergent and a liquid detergent.

The powder detergent is generally widely used, but due to the characteristics of the detergent, it becomes moist when contacted with moisture, and the detergent powder aggregates with each other, thereby clogging the detergent outlet 121.

On the other hand, there is an inconvenience in that the liquid detergent should be used by dropping an appropriate amount into the liquid detergent storage unit 120 each time it is washed.

In the present invention, the disadvantages of the liquid detergent can be solved at once.

To this end, the detergent supply device 110 according to the present invention may include a liquid detergent storage unit 120 and a powder detergent storage unit 140 inside the detergent box 112.

The liquid detergent storage unit 120 and the powder detergent storage unit 140 may be provided on left and right sides.

A cover plate 129a may be provided on one side of the upper surface of the liquid detergent storage unit 120, and an injection hole may be provided on the other side of the upper surface thereof.

Since the opening and closing plate 129b is provided on the other side of the upper surface of the liquid detergent storage unit 120, washing water can be prevented from flowing into the liquid detergent storage unit 120 through the water supply hole of the water distribution unit 130.

The opening and closing plate 129b has a rear end portion coupled to one end portion of the cover plate 129a in a hinge structure, and the front end portion thereof rotates in an up-down direction to open and close the liquid detergent storage unit 120.

In this case, when additional liquid detergent is added to the liquid detergent storage unit 120, the opening/closing plate 129b can be opened, and the opening/closing plate 129b is closed at normal times to supply the water supply hole of the water supply distribution unit 130. It is possible to prevent the washing water from flowing into the liquid detergent storage unit 120.

The liquid detergent storage unit 120 includes a pumping unit 122 and a discharge unit 123c, so that an appropriate amount of the liquid detergent stored therein may be extracted for each washing.

The liquid detergent storage unit 120 may have a box structure horizontally placed inside the detergent box 112.

The pumping means 122 may be provided in the liquid detergent storage unit 120.

The pumping means 122 may be implemented as a gear (122a, 122b) pump operated by a pair of gears (122a, 122b).

The gear (122a, 122b) pump is provided with a pair of gears (122a, 122b) rotating to mesh with each other, each of the gears (122a, 122b) may rotate in opposite directions while circumscribed to each other.

The gear (122a, 122b) pump may pump a liquid detergent from one side to the other side with the gears (122a, 122b) interposed therebetween.

A liquid detergent outlet 121 is provided at the bottom of one end of the liquid detergent storage unit 120, and the liquid detergent may be discharged to the outside through the liquid detergent outlet 121.

The bottom surface of the liquid detergent storage unit 120 may be formed to be inclined downward toward the liquid detergent discharge port 121.

That is, the height of the bottom surface of the other side of the liquid detergent storage unit 120 may be gently inclined so as to decrease toward the liquid detergent discharge port 121.

Accordingly, the liquid detergent stored in the liquid detergent storage unit 120 is collected by gravity to the liquid detergent discharge port 121, so that the flow of the liquid detergent can be maintained smoothly.

The liquid detergent discharge port 121 may be formed to communicate with the inlet port of the gears 122a and 122b.

The liquid detergent is discharged from the liquid detergent storage unit 120 through the liquid detergent outlet 121 and supplied to the gears 122a and 122b pumps, and is pumped from the gears 122a and 122b through the discharge unit 123c. Can be discharged.

The pumping means 122 may selectively supply the detergent discharged from the discharge port 121 to the tub.

The'detergent is selectively supplied by the pumping means 122.' "" may mean that the detergent supply is intermittently performed.

For example, since the detergent will be pumped by the pumping means 122 while the pumping means 122 is being driven, in this case, the detergent can be supplied to the tub, while the idle period in which the pumping means 122 is not driven. During the period, since the detergent will not be pumped by the pumping means 122, in this case, the detergent is not supplied to the tub.

The reason why the detergent is selectively supplied by the pumping means 122 in this way is not that the user determines an appropriate amount of liquid detergent for each washing and puts it into the detergent box 112, but the detergent is intermittently supplied by the pumping means 122. This is to ensure that it is supplied to the tub.

The amount of detergent pumped by the pumping means 122 may be adjusted by the rotation speed of the gears 122a and 122b.

The faster the rotational speed of the gears 122a and 122b, the faster the pumping speed and the pumping amount increases.

Therefore, the proper amount of liquid detergent injected into the tub every washing can be adjusted by controlling the rotation speed of the gears 122a and 122b using the detergent supply amount control knob (or detergent supply amount control button) provided on the control panel 103. I can.

The pumping means 122 may include a flow path forming plate 123 coupled to cover the outlet 121 of the liquid detergent storage unit 120.

The flow path forming plate 123 may include an inlet portion 123a disposed to face the outlet 121 of the liquid detergent storage unit 120.

Like the outlet 121 of the liquid detergent storage 120, the inlet 123a is preferably located on the bottom of the rear surface of the liquid detergent storage 120.

This is because, when the outlet 121 and the inlet 123a are formed as low as possible, the liquid detergent stored in the liquid detergent storage unit 120 can be discharged as much as possible.

The flow path forming plate 123 may include a supply flow path 123b connecting one side of a pump of the gears 122a and 122b of the pumping means 122 and the other side thereof.

The supply passage 123b may connect the inlet part 123a and the discharge part 123c.

In this case, the supply passage 123b moves the detergent pumped by the pumping means 122 to the discharge part 123c, thereby pumping the detergent pumped through the discharge port to the tub.

The pumping means 122 may be driven by an actuator 127.

The actuator 127 may be a driving motor generating rotational force.

The driving motor may be installed on the rear surface of the dispenser housing 150.

The driving motor may be accommodated in the motor housing 128.

The driving motor may be fixedly coupled to the inside of the cabinet 101 by a fixing bracket.

The driving motor may be controlled by receiving an electrical control signal from a detergent supply amount control knob of the control panel 103.

The user may manually adjust the amount of detergent supplied by using the detergent supply amount control knob, or may be automatically set according to a preset default value for each washing mode.

The driving motor may generate rotational force by receiving 3-phase AC power from the outside.

The rotational force generated by the driving motor may be output through a driving shaft 126 protruding out of the motor housing 128.

The drive shaft 126 may protrude from one end of the motor housing 128 and may be formed to protrude inward from the rear surface of the dispenser housing 150.

The pumping means 122 may be connected to a driving motor through a coupler 125 to receive power.

The coupler 125 may include a driving gear 125a and a driven gear 125b.

The drive gear 125a may be rotatably coupled to the drive shaft 126.

The driven gear 125b may be coupled to the driving gear 125a to mesh with each other.

The gears 122a and 122b of the gears 122a and 122b may be rotatably supported by bearings provided at both ends between the flow path forming plate 123 and the rear end of the liquid detergent storage unit 120.

The gears 122a and 122b of the gears 122a and 122b and the pump may each include a rotation shaft 122b'.

The gears 122a and 122b and the rotation shaft 122b' provided in any one of the gears 122a and 122b of the pump may be formed to be long in the axial direction.

One end of the rotation shaft 122b' may be directly connected to the center of the gears 122a and 122b, and the other end of the rotation shaft 122b' may be connected to the driven gear 125b.

The flow path forming plate 123 may have a through hole for passing through the rotation shaft 122b'.

Since the liquid detergent may leak from the liquid detergent storage unit 120 through the through hole, a sealing material 124 may be provided around the through hole.

The sealing material 124 may surround the through hole in a ring shape.

The sealing material 124 may be provided on a rear surface of the flow path forming plate 123, that is, a surface opposite to a surface facing the liquid detergent storage unit 120.

A sealing material 124 support part 123d may be formed to protrude in a circular shape on the back surface of the flow path forming plate 123 so that the sealing material 124 may be fixed.

The sealing material 124 has a circular shape, and since it is inserted into the sealing material 124 support part 123d, the gap between the rotating shaft 122b' and the through hole may be sealed.

The rotation shaft 122b' may pass through the sealing material 124 and be coupled to the driven gear 125b.

The pumping mechanism and the pumping action of the liquid detergent will be described in detail according to the connection relationship of this configuration.

As the driving motor is operated, the driving shaft 126 protruding from the motor housing 128 to the inside of the dispenser housing 150 may be rotated.

Then, the drive gear 125a coupled to the drive shaft 126 rotates, and the driven gear 125b engaged with the drive gear 125a also rotates.

As the drive gear 125a and the driven gear 125b rotate, power is transmitted to the pumping gears 122a and 122b, which are pumping means 122, through a rotation shaft 122b' penetrating the flow path forming plate 123. .

One of the gears 122a and 122b of the gears 122a and 122b of the pump rotates by receiving power from the rotational shaft 122b', and the remaining gears 122a and 122b are engaged with the gears 122a and 122b. Since the gears 122a and 122b are also interlocked, the pumping force is generated by the rotation of the gears 122a and 122b.

The liquid detergent flows through the inlet 123a of the flow path forming plate 123 from the outlet 121 formed at the bottom of the rear end of the liquid detergent storage unit 120 by the pumping force, and the gears 122a and 122b enter the pump. It is supplied to the side, and the supplied liquid detergent may be compressed while passing through a pair of gears 122a and 122b meshed with each other.

The compressed liquid detergent is supplied to the discharge part 123c through the supply passage 123b of the flow path forming plate 123, and flows downward from the discharge part 123c.

As a method for supplying and injecting liquid detergent into the liquid detergent storage unit 120, there may be a method of manually injecting the liquid detergent into the detergent box 112 by a user, and a method of automatically supplying it from an external liquid detergent supply hose. have.

However, the automatic supply method by the liquid detergent supply hose may be performed by operating the water level sensor inside the liquid detergent storage unit 120.

The liquid detergent stored in the liquid detergent storage unit 120 may be supplied to the inlet part 123a of the flow path forming plate 123 from the outlet 121 formed on the bottom of the liquid detergent storage unit 120.

Subsequently, the liquid detergent supplied to the inlet portion 123a of the flow path forming plate 123 is compressed while flowing into the gears 122a and 122b meshed with each other by the gears 122a and 122b.

The compressed liquid detergent may fall into the space 152 of the dispenser housing 150 through the discharge portion 123c of the flow path forming plate 123 via the supply flow path 123b.

The dropped liquid detergent may meet the washing water descending from the upstream side of the space part 152 and be supplied to the tub through the water supply passage 151.

Meanwhile, the powder detergent storage unit 140 may be disposed parallel to the side of the liquid detergent storage unit 120 with a partition wall therebetween.

In addition, the powder detergent storage unit 140 may be located behind the right side of the detergent box 112.

In addition, since the upper surface of the powder detergent storage unit 140 is opened or an opening is formed in the upper surface, the washing water falls into the powder detergent storage unit 140 from the water supply hole of the water supply distribution unit 130 through the opened surface. Can be stored temporarily.

The powder detergent storage unit 140 may include a siphon pipe 141 therein to prevent the detergent outlet 121 from being blocked by the powder detergent lumped together.

The siphon tube 141 may be formed protruding upward from the bottom of the powder detergent storage unit 140 in which all sides are blocked.

A cover plate 142 covering the upper surface of the powder detergent storage unit 140 may be provided on the siphon tube 141.

An opening is formed on one side of the cover plate 142 so that washing water may fall from the water supply hole of the water supply distribution unit 130 through the opening.

A siphon cover tube 143 is provided on the lower surface of the other side of the cover plate 142 to cover the siphon tube 141.

The siphon cover tube 143 is relatively larger than the diameter of the siphon tube 141.

Accordingly, a siphon flow path may be formed between the outer diameter surface of the siphon tube 141 and the inner diameter surface of the siphon cover tube 143.

The powder detergent injected into the powder detergent storage unit 140 and the washing water supplied through the water supply hole of the water distribution unit 130 may be mixed with each other.

The powder detergent is a hydrophilic material that is easily soluble regardless of cold or hot water, and can be dissolved even if it is temporarily immersed in water.

It may take a certain time until the washing water supplied from the water supply hole of the water supply distribution unit 130 reaches the height of the siphon pipe 141, and the powder detergent injected into the powder detergent storage unit 140 during that time is Can be dissolved in

In other words, since the inner space of the detergent powder storage unit 140 is sealed, the detergent powder may be immersed in the washing water for a certain period of time until the washing water reaches the height of the siphon pipe 141, mixed, and dissolved.

When the washing water in which the powder detergent is dissolved becomes higher than the height of the siphon pipe 141, the washing water containing the detergent rides through the siphon passage between the siphon pipe 141 and the siphon cover pipe 143 by the siphon principle. After going up, it may flow into the siphon pipe 141 at its peak and fall down.

Here, the siphon passage is sufficient to pass the washing water in which the powder detergent is dissolved, but the powder detergent lumped into a lump cannot pass through.

Therefore, the siphon pipe 141 may act to promote the powder detergent to be sufficiently dissolved in the washing water, and the siphon cover pipe 143 and the siphon pipe 141 prevent the inflow of agglomerated powder detergent. I can.

In addition, in order to better dissolve the powder detergent in the washing water, a stirrer may be provided inside the powder detergent storage unit 140.

The stirrer may be rotated using a fluid flow such as a pinwheel or a waterwheel.

The stirrer may be implemented by a bucket rotating in a vertical direction and a rotating shaft 122b' supporting the same.

The agitator may be rotated using the potential energy of the washing water falling from the water supply hole of the water distribution unit 130 as a power source.

For example, as the falling washing water is contained in the bucket, the bucket rotates to stir the washing water.

Due to this, the powder detergent can be effectively dissolved in the washing water without agglomeration.

A water level sensor is provided inside the powder detergent storage unit 140 so that the washing water may be supplied to the powder detergent storage unit 140 so that the height of the siphon pipe 141 is maintained.

Hereinafter, a movement path of the powder detergent disclosed in the present specification will be described with reference to FIG. 8.

8 is a cross-sectional view showing a movement path of washing water in which the powder detergent is dissolved in the powder detergent storage unit 140 according to the present invention.

Since the powder detergent is solid due to the nature of the detergent, it can be supplied to the tub by dissolving the detergent powder in water.

After the user pulls out the detergent box 112 in front of the cabinet 101 for washing, an appropriate amount of detergent powder may be injected into the detergent powder storage unit 140.

Washing water is supplied from a water supply source to the water supply distribution passage of the water supply distribution unit 130, and the washing water distributed through the water supply distribution passage is introduced into the powder detergent storage unit 140 through a water supply hole formed at the bottom of the distribution plate 132 Can be.

Washing water introduced from the water supply hole may flow into the powder detergent storage unit 140 through an opening formed in the upper cover plate 142 of the detergent powder storage unit 140.

The washing water introduced into the powder detergent storage unit 140 is mixed with the powder detergent, and the powder detergent may be dissolved in the washing water.

As the amount of the detergent solution (hereinafter, referred to as detergent solution) in which the powder detergent is dissolved in the powder detergent storage unit 140 increases, the height of the detergent solution increases higher than the height of the siphon tube 141, and the detergent solution It moves to the apex of the siphon tube 141 through the siphon flow path between the phone cover tube 143 and the siphon tube 141.

Subsequently, the detergent liquid flows into the pipe at the apex of the siphon pipe 141 and goes down the pipe.

The detergent liquid descending through the siphon pipe 141 falls into the detergent liquid drainage passage 144 provided on the bottom of the detergent box 112, and the detergent liquid flows down to the bottom of the detergent box 112 and eventually the dispenser housing ( It may be supplied to the tub through the water supply passage 151 of 150).

Therefore, according to the present invention, as the pumping means 122 provided in the liquid detergent storage unit 120 is selectively driven, the appropriate amount of the liquid detergent is not determined by the user, but is automatically set in the detergent supply device 110. It can be supplied, and since the user can set a desired amount as needed, inconvenience in the conventional detergent supply can be eliminated.

In addition, by providing a siphon pipe 141 in the powder detergent storage unit 140, the powder detergent and washing water can be temporarily stored in a closed space until the powder detergent is sufficiently dissolved in the washing water, and the height of the siphon pipe 141 In the above, washing water in which the powder detergent is dissolved can be supplied.

In addition, by narrowing the passage through which the detergent solution passes through the siphon pipe 141 and the siphon cover pipe 143, it is possible to prevent the powder detergent lump from clogging the conventional detergent outlet 121.

The preferred embodiments of the present invention described above are disclosed in order to solve the technical problem, and if a person having ordinary knowledge in the technical field to which the present invention belongs (a person skilled in the art) various modifications, changes, additions, etc. This will be possible, and such modifications should be seen as falling within the scope of the following claims.
