Description

  The present invention relates to the field of washing machines, and more particularly to a washing machine provided with a water intake filtration device.

  The washing machine includes a main body that constitutes a bottom surface and a side surface, and a top cover that is installed on an upper portion of the main body. Inside the main body, the water tank is supported by a plurality of supports, and after the clothes are put into the water tank, a washing tub for washing and dewatering work is installed, and a pulsator is installed inside the washing tub Is done.

  Behind the top cover, a detergent case rack into which the detergent case can be inserted or removed, a water supply pipe connected to the detergent case rack, and a water intake valve connected to the water supply pipe are installed. A filtration device is installed inside.

  At the center of the top cover, a lid is installed so that the user can put the laundry into the laundry tub or take it out of the laundry tub. An operation panel is installed on the upper rear side of the top cover, and a control member such as a control device for controlling various operations of the washing machine is installed on the bottom surface of the operation panel.

  In the washing machine having the above structure, the user opens the lid and puts the laundry into the washing tub. Further, when a necessary washing operation is input with an input button provided on the operation panel, the water intake valve is opened, and the washing water flows into the washing tub up to the set water level.

  Thereafter, the motor is driven, the driving force of the motor is appropriately reduced and transmitted to the pulsator or the washing tub, and the washing operation is performed. When the washing operation is completed, the rinsing operation is performed several times. When the rinsing operation is completed, the washing tub is rotated at the same time as the dehydrating operation is performed, and a series of related washing processes are completed.

  However, in many areas such as rural areas, and in some countries and areas outside the country, the quality of tap water is relatively inferior. Or the water will not be taken, and the washing machine cannot be used normally. Due to the limitations of the intake valve structure, current intake pipes and intake valves are basically standard connector designs. Since the filter at the intake port is limited in space, the area cannot be increased, the amount of filtered water is small, and clogging tends to occur. The water intake is relatively small and difficult to remove and clean.

  In contrast to the fact that most of the filter 3 ′ installed in the water intake 2 ′ of the existing water intake valve 1 ′ does not have a removable structure (see FIG. 1), the filter 3 ′ of the water intake valve, for example, Several improvements have been made, such as adding one knob 4 '(see FIG. 2). The cylindrical knob and the support frame are integrally formed by injection molding, and an iron filter is also integrally formed inside thereof. Although it can be conveniently removed and cleaned without using a tool in this way, the problem of frequent removal cannot be prevented because there are many foreign objects.

  Chinese Patent Application No. 03130294.7 discloses the structure of a filtration device in a water intake valve of a washing machine. The structure includes a water intake valve installed in the water supply flow path of the washing machine, and a filtration device is installed inside the valve top of the water intake valve. The structure of this filtration device includes a knob, a filter, and a support frame surrounding the periphery of the filter, and a reticulated second filtration device is further installed inside the filtration device. Although a secondary filtration structure has been added, when the filter is removed due to clogging, the intake pipe must still be removed from the intake valve portion, and the intake valve and intake pipe must ensure a good seal. Therefore, installation and removal are not convenient, and there is always a problem of water leakage due to insufficient installation.

  In view of this, the present invention is particularly shown.
