Definitions
- the present invention relates to a washing machine, and more particularly, to a detergent dispensing apparatus of a washing machine, which can effectively dispense the detergent.
- a drum-type washing machine performs its washing cycle by manipulating a control unit provided at a front portion.
- the drum-type washing machine includes a detergent dispensing container for dispensing a detergent and/or softener during the washing cycle.
- a door is formed on the front portion of the drum-type washing machine.
- a tub is installed inside of the washing machine and a drum is rotatably installed in the tub. The door is opened and the laundry is loaded in the drum, after which the water and detergent are supplied into the drum.
- the drum rotates by a driving motor to wash the laundry.
- a typical drum-type washing machine includes a main body formed in a predetermined shape, a drum installed inside of the main body, a tub for enclosing the drum and reserving the washing water, a driving motor for rotating the drum, a detergent container for dispensing the detergent, a water supply pipe connected to the detergent container to supply the washing water or the washing water mixed with the detergent, a drain pipe for draining the used washing water in the washing cycle to an external side, and a pump and drain hose connected to the drain pipe to forcedly drain the washing water.
- the drum-type washing machine has been improved in its function. For example, a heat-drying function is added to the drum-type washing machine.
- the detergent dispensing container for dispensing the detergent and softener is formed on the front portion, i.e., the front left-upper portion thereof.
- the user withdraws the detergent container from the washing machine and fills the detergent container with a proper type and amount of the detergent. Since the laundry may be formed of a variety of materials, a proper detergent must be selected according to the materials of the laundry. Therefore, the user must select the proper amount or type of detergent according to an amount and material of the laundry and fill the same into the detergent dispensing container.
- the filling of the detergent with the detergent dispensing container by himself/herself is troublesome for the user. That is, the user selects the proper type of the detergent, measures the proper amount using, for example, a measuring spoon, and dispenses the measured detergent to the detergent dispensing container by himself/herself. In this case, it is difficult to accurately dispense the detergent and the detergent. Thus, the detergent may pollute around the washing machine. The measuring spoon must be frequently cleaned. This is troublesome for the user.
- the present invention is directed to a detergent dispensing apparatus of a washing machine, which substantially obviate one or more problems due to limitations and disadvantages of the related art.
- a detergent dispensing apparatus of a washing machine including: a main body of the washing machine; a detergent cartridge separately received in the main body and storing a detergent therein; a detergent outlet formed on the detergent cartridge to define a detergent dispensing passage; and an opening/closing assembly for selectively opening and closing the detergent outlet.
- a detergent dispensing apparatus of a washing machine including: a main body of the washing machine; a cartridge receiving body formed on the main body; a detergent cartridge separately received in the cartridge receiving body and storing a detergent therein; a detergent outlet form on the detergent cartridge to define a detergent dispensing passage; and a cap for opening/closing the detergent outlet.
- a detergent dispensing apparatus of a washing machine including: a main body of the washing machine; a drawer insertion portion formed on the main body; a cartridge receiving drawer separately inserted in the drawer insertion portion; and a detergent cartridge separately received the cartridge receiving drawer and storing a detergent therein.
- the dispensing of the detergent or softener can be effectively realized and the initial installed and replacement of the detergent cartridge can be easily realized.
- the dispensing of the detergent can be prevented. Furthermore, since the detergent outlet is selectively opened, the detergent hardening phenomenon by the moisture that may be introduced through the detergent outlet can be minimized.
