A concave concave portion 70 recessed by a predetermined depth is formed on the bottom surface of the blower case 52a provided with the mounting plate 68. This is to allow foreign matter on the bottom surface of the blower case 52a, in particular, water to flow naturally into the concave portion 70 by its own weight.

A plurality of drain holes 72 are formed in the concave inlet 70. The drain hole 72 is to allow the water introduced into the concave portion 70 to be discharged to the outside of the air cleaner 50 naturally. Of course, the bottom surface of the concave portion 70 may be formed to be inclined toward the drain hole (72).

A guide part 74 is provided on one side of the bottom surface of the blower case 52a. The guide portion 74 is composed of a plurality of ribs 74a and support jaw 74b protruding to a predetermined height to guide the installation of the lead wire 92 to be described below and to protect the lead wire 92. It plays a role.

The front of the case 52 is provided with a decoration housing (80). The decor housing 80 is composed of a front portion, an upper and a lower portion, and both side portions to surround the opened front and front edges of the case 52 in a state in which the blower case 52a and the filter case 52b are coupled to each other.

A discharge opening O and a filter mounting opening 82 are formed at the front portion of the decor housing 80. The discharge port O is positioned at the front end of the discharge flow path B, and the basket door 59 of the filter part 54 is mounted inside the filter case 52b through the filter mounting opening 82. do.

It is provided. One side of the operation unit 86 is provided with a display unit 88 for displaying various information about the operation of the air cleaner 50 to the outside.

In addition, a printed circuit board 90 mounted with various electric elements for controlling the display unit 88 and the air blowing unit 60 by the operation unit 86 is installed on the upper end of the mounting plate 68. A lead wire 92 is provided to transmit an electrical signal between the printed circuit board 90, the blowing unit 60, the operation unit 86, and the display unit 88.

The lead wire 92 is mounted along the guide portion 74. The lead wire 92 may be positioned to be spaced apart from the bottom surface of the blower case 52a by a predetermined height by the support jaw 74b of the guide portion 74. In addition, foreign matters such as water flowing into the bottom surface of the blower case 52a by the rib 74a of the guide portion 74 are prevented from contacting the lead wire 92.

Hereinafter, the operation of the refrigerator air cleaner according to the present invention having the configuration as described above will be described in detail.

First, the process of installing the printed circuit board 90 and the lead wire 92 will be described. The printed circuit board 90 on which various electric elements are mounted is installed on the top of the mounting plate 68. When the printed circuit board 90 is installed on the top of the mounting plate 68, the printed circuit board 90 is positioned at a predetermined height on the bottom surface of the blower case 52a. In addition, the printed circuit board 90 is supported by the support piece 68 ', so that the printed circuit board 90 does not flow horizontally.

In addition, a plurality of lead wires 92 connected to the printed circuit board 90, the operation unit 86, the display unit 55, and the blowing unit 60 are installed in the guide unit 74. In particular, the lead wire 92 is positioned above the support jaw 74b, and like the printed circuit board 90, the lead wire 92 has a predetermined height at the bottom surface of the blower case 52a. Will be located. The rib 74a of the guide portion 74 serves as a sidewall of a space in which the lead wire 92 is installed, and guides the lead wire 92 not to be separated from a predetermined position.

Next, referring to the operation process of the air cleaner 50, the user manipulates the manipulation unit 86 to input an operation signal for operating the air cleaner 50. When the operation signal is input in this way, the decoration panel 84 is moved forward by the driving device (not shown) and the interlocking member (not shown) installed in the decoration housing 80 to open the discharge port O. .

In addition, the blower unit 60 is operated to suck air into the case 52 through the suction port I. The air sucked through the suction port I is purified by passing through the filter unit 54 in a state in which relatively large dust and the like of foreign substances in the air are filtered out by the suction grill G.

Thus, the purified air passing through the filter unit 54 in turn is guided to the blowing unit 60 by the suction flow path (A). In addition, the blower unit 60 is guided to the discharge passage B through the blower unit 60 by continuous driving of the blower unit 60, and discharged to the outside through the discharge port O. At this time, the air discharged through the discharge port (O) is discharged together with the negative ions generated by the negative ion generating device 66, is guided by the back surface of the decor panel 84 is discharged through the upper or lower.

Next, the drainage process when water or the like is introduced into the air cleaner 50 will be described.

When water is introduced into or generated inside through the inlet port I of the air cleaner 50, the water passes through the filter unit 54 and the water inflow rate is extremely decelerated, thereby filtering the filter case 52b. It flows along the bottom surface of the, and flows to the ventilation case 52a.

The water flowing into the blower case 52a flows along the bottom surface of the blower case 52a, and naturally flows into the indentation portion 70 recessed from the bottom surface by the weight of water. The water introduced into the concave portion 70 is naturally discharged to the outside of the air cleaner 50 through the drain 72 formed in the concave portion 70 by its own weight.

Therefore, water does not accumulate on the bottom surface of the blower case 52a. In addition, since water is not accumulated on the bottom surface, water does not collect on the bottom surface by the height of the mounting plate 68 on which the printed circuit board 90 is installed and the guide portion 74 on which the lead wire 92 is installed. Is not in contact with the printed circuit board 90 and the lead wire 92 at all.

It is to be understood that the invention is not limited to the disclosed embodiments, but is capable of many modifications and alterations, all of which are within the scope of the appended claims. It is self-evident.

In the air cleaner for a refrigerator according to the present invention as described in detail above, the following effects can be expected.

Install the printed circuit board and lead wire on the top of the mounting plate and guide to prevent water from directly contacting the printed circuit board and lead wire even if water is accumulated on the bottom of the blower case. By providing water to drain to the outside, even if water is introduced into the interior of the air purifier reduces the risk of short circuit has the effect of increasing the stability against fire, electric shock, leakage.
