Description

  The present invention relates to a washing machine, and more particularly, to a washing machine in which an internal space can be easily utilized by installing a detergent charging unit on a door.

  In general, a washing machine is subjected to processes such as washing, rinsing and dehydration to remove contaminants such as clothes, bedding, etc. (hereinafter referred to as 'cloth') contained in a drum by using the action of water and detergent. An apparatus for cleaning a cloth, comprising a detergent charging device for supplying a detergent mixed with water to a tub.

  FIG. 1 is a side sectional view showing an internal configuration of a conventional washing machine, and FIG. 2 is a perspective view showing a state in which the detergent box shown in FIG. 1 is pulled out of the washing machine.

  As shown in FIGS. 1 and 2, a conventional washing machine has a cabinet 2 in which a cloth take-in / out hole 1 is formed on one side, and water that is supported in the cabinet 2 so as to be buffered, and in which a detergent is dissolved (hereinafter, referred to as “cleaning machine”). A tab 10 for storing clean water in which the detergent is not dissolved (hereinafter referred to as “rinsing water”) and a drum 12 that is rotatably disposed inside the tab 10 and stores the cloth m. And a motor 14 having a shaft 13 for supporting and rotating the drum 12, a water supply device 16 for supplying water, a detergent is contained, and the water supplied by the water supply device 16 passes therethrough. By doing so, it is comprised including the detergent injection | throwing-in apparatus 20 for supplying the water which the detergent melt | dissolved to the said tub 10, and the drainage device 30 for discharging | emitting the contaminated water in the said tub 10. FIG.

  A door 4 for opening and closing the cloth taking-in / out hole 1 is rotatably connected to the cabinet 2.

  A control panel 7 for operating the washing machine is installed at the upper part on the front side of the cabinet 2.

  On the left and right sides of the control panel 7 are formed detergent box loading / unloading holes 8 for loading and unloading detergent boxes described later.

  The drum 12 is formed with a through hole 13 through which washing water or rinsing water supplied to the tub 10 flows into the drum 12 in order to wet the cloth m.

  The detergent charging device 20 is inserted through the detergent box loading / unloading hole 8 at the rear of the detergent box loading / unloading hole 8 of the control panel 7 and is stored inside the detergent box housing 21. In addition, a detergent box 22 having a detergent container 22a for containing detergent, and a back surface of the control panel 7 so as to be positioned above the detergent box housing 21 and supplying water supplied through the water supply device 16 to the water. And a dispenser 23 for supplying to the detergent box 22.

  A water supply bellows 24 for guiding washing water or rinsing water that has passed through the detergent box 22 into the tub 10 is connected to the detergent box housing 21.

  Reference numeral 11 denotes a bellows connection port formed in the tab 10 in order to connect the water supply bellows 24 to the tab 10.

  In the conventional washing machine configured as described above, the detergent box 22 is pulled forward, the detergent or softener is put into the detergent container 22a of the detergent box 22, and then the detergent box 22 is placed in the detergent box housing 21. The detergent box 22 is housed inside the detergent box housing 21.

  Thereafter, the cloth m is put in through the cloth take-in / out hole 1, the door 4 is closed, and then an operation command is input through the control panel 7, the washing machine, according to the input command, the motor 14, the water supply device 16. And the drainage device 30 is operated.

  When a washing process is input, the washing machine operates the water supply device 16 to guide water supplied from the outside to the dispenser 23, and the dispenser 23 supplies the supplied water to the detergent box 22. Fall. Next, the water dropped into the detergent box 22 is discharged into the detergent box housing 21 while being dissolved in the detergent, and then supplied to the inside of the tab 10 through the water supply bellows 24.

  The water (washing water) dissolved in the detergent and supplied to the tub 10 flows into the drum 12 through the through hole 13 of the drum 12 in order to wet the cloth.

  After the water supply as described above is performed, the drum 12 is rotated by the drive of the motor 14, so that the contaminants on the cloth in the drum 12 are removed by the action of the washing water.

  Meanwhile, after the washing process is performed for a predetermined time, the drainage device 30 discharges the contaminated water in the tub 10 to the outside of the washing machine.

  After the water supply, washing and drainage as described above are performed, the washing machine confirms whether or not the rinsing process can be input, and when the rinsing process is input, the water supplied from the outside by the operation of the water supply device 16. Is guided to the dispenser 23, and the dispenser 23 drops the supplied water into the detergent box 22. Next, the water dropped into the detergent box 22 is supplied to the inside of the tub 10 through the detergent box housing 21 and the water supply bellows 24.

  The water (rinsing water) supplied to the tub 10 in which the detergent is not dissolved wets the cloth as in the washing process, and when the drum 12 is rotated by driving the motor 14, the water in the drum 12 The fabric foam is rinsed by the action of rinsing water.

  Meanwhile, after the rinsing process as described above is performed for a predetermined time, the drainage device 30 discharges the contaminated water in the tub 10 to the outside of the washing machine.

  However, since the conventional washing machine occupies a large space inside the washing machine of the detergent charging device 20, the volume of the washing machine increases. Furthermore, since there are many parts, such as the detergent box housing 21 and the water supply bellows 24, there existed a problem that an assembly process became complicated.

  In addition, since the bellows connection port 11 is formed in the tab 10, there is a problem that the forming of the tab 10 becomes complicated and the manufacturing cost increases.

  The present invention has been made to solve the above problems, and provides a washing machine capable of reducing the volume, minimizing the number of parts and the assembly process, simplifying the forming of the tab, and reducing the manufacturing cost. With the goal.

  In order to achieve the above object, a washing machine according to the present invention includes a cabinet in which a cloth take-in / out hole is formed, a door for opening / closing the cloth take-in / out hole, a tab mounted in the cabinet, The drum includes a drum that is rotatably disposed inside the tab and receives a cloth, and a detergent charging portion formed on the door.
