The present invention relates to a water purifier of a refrigerator. More particularly, the present invention relates to a water purifier of a refrigerator, in which a filter for purifying raw water introduced into the refrigerator to be supplied to an ice maker or a dispenser can be easily replaced from the refrigerator.

In general, a large refrigerator may be separately iced or defrosted or stored and eaten, or may be provided with a water purifier capable of purifying raw water from the refrigerator itself, ice-making it, or supplying it to a dispenser for drinking.

Recently, with the pursuit of convenience in the kitchen life of the home, many people use a refrigerator equipped with a water purifier, instead of receiving a separate purified water in the refrigerator or making ice in a separate container and drinking it. There is a situation.

However, in the case of the refrigerator equipped with the water purifier, a filter of a purifier that purifies external raw water is mounted on the inner rear wall case of the refrigerator to purify the incoming raw water, and the purified water is sent to an ice maker or a dispenser to make ice. Or drinking.

Therefore, when replacing the filter of the water purifier of the refrigerator, the replacement operation must be performed while opening the door of the refrigerator and taking out the food stored therein, so that the power consumption due to a lot of cold air leakage increases, I had a problem that bothered me.

Therefore, as shown in FIG. 1, a water purifier is provided at the bottom of the door 2 of the refrigerator 1 to facilitate the replacement of the filter of the water purifier. However, in the case of the water purifier, A filter (3) for purifying raw water is inserted into the filter holder (4), and a raw water valve (5) into which raw water flows in front of the filter holder (4), and outflow of water purified by the filter (3). The drain valve 6 is provided, the drain valve 6 is connected to the hose (7) and the solenoid valve (8) for outflow and blocking to the ice maker or dispenser; Raw water solenoid valve 9 is coupled to the raw water inlet and shut off. At this time, the solenoid valve 8 and the raw water solenoid valve 9 is mounted on the inner rear wall of the refrigerator.

Therefore, the raw water flowing through the raw water valve 5 mounted on the filter holder 4 is purified by the filter 3, and then the ice maker or dispenser is discharged through the drain valve 6, the hose 7 and the solenoid valve 8. It is possible to drink purified water while supplying it.

When the filter 3 is to be replaced while drinking the purified water using the water purifying device as described above, the door 2 of the refrigerator 1 is not opened, and the filter 3 is removed from the lower filter holder 4 of the refrigerator 1. Since the filter 3 is pulled out in the forward state, there is a convenient point that the filter 3 can be replaced conveniently.

However, when the filter 3 is pulled out, the filter holder 4 is pulled out while being replaced. Therefore, when the filter 3 is sometimes strongly pulled out, the raw water valve 5 or the drain of the filter holder 4 is removed. Similarly, there was a risk that the valve 6 would easily come off from the hose 7 and had to be troublesome to be replaced with care.

In addition, the water purifying device is configured to draw only the filter holder 4 when the filter 3 is drawn out, and is coupled to the filter holder 4 and the hose 7 to supply and block purified water to the ice maker and the dispenser. Since the valve 8 is located on the rear wall of the refrigerator, for example, when an error occurs in the solenoid valve 8 and the replacement is to be repaired, the valve 8 has a troublesome problem in that the rear wall of the refrigerator needs to be removed.

Therefore, an object of the present invention is to mount the water purifier provided in the refrigerator in the filter drawer to facilitate the replacement and repair of the water purifier by opening and closing the filter drawer.

Another object of the present invention is to combine the solenoid valve with the filter drawer to simplify the overall configuration of the water purifying device, thereby simplifying the assembly of the device and greatly improving the reliability of the water purifying device.

In order to achieve the above object, the present invention provides a top and front and rear case is mounted to the lower door of the refrigerator; The filter drawer is inserted into the case and the filter drawer is equipped with a filter for supplying purified water to the ice maker and the dispenser.

The filter drawer may include a solenoid valve for supplying and blocking the raw water flowing into the tip of the filter and supplying it to the ice maker and the dispenser by electrical signals; A flow path valve inserted into the solenoid valve to supply and block purified water; A filter having a filter holder inserted into the flow path valve; It is composed of a rotary knob for fixing the filter holder to the flow valve.                         

Therefore, according to the present invention, by replacing the filter for supplying the purified water to the ice maker and the dispenser of the refrigerator to the filter drawer coupled to the case mounted to the lower part of the refrigerator, it is possible to easily replace the filter, The configuration of the device can be simplified, and the reliability of the water purifying device can be improved.
