As illustrated, the refrigerator includes a main body 11 in which a freezing compartment 21 and a refrigerating compartment 31 are formed, respectively, with partitions 12 formed in the vertical direction, and the freezing compartment 21 and the refrigerating compartment 31. It is provided with a freezing chamber door 23 and a refrigerating chamber door 33 which are hinged to the main body 11 so as to be able to rotate and open each front opening.

In the rear region of the freezing chamber 21, a cold air duct 22 having a plurality of cold air discharge outlets is installed to discharge cold air forward, and spaced apart from each other along the vertical direction in the front area of the cold air duct 22. A plurality of shelves 27 are provided to support food. An ice maker 29 is installed in the upper region of the freezing chamber 21 to generate ice.

An upper duct 35 is provided in the upper rear region of the refrigerating compartment 31 to receive cold air from the freezing compartment 21 and discharge the cold air to the front and the lower sides of the refrigerating compartment 31. A plurality of shelves 37 are arranged to be spaced apart from each other and support food. In the lower region of the refrigerating chamber 31, a vegetable chamber 39 is formed to store vegetables and fruits, and a water storage tank (mido) is provided in the rear region of the vegetable chamber 39 so that cold water can be supplied to the dispenser 25 which will be described later. Si) is placed.

The freezer door 23 and the refrigerating chamber door 33 are provided with a plurality of baskets 24 and 34 spaced apart from each other along the up and down directions so that food can be stored and stored therein. Dispenser 25 is provided to extract ice and water without opening the freezer door 23.

By the way, in such a conventional refrigerator, the air of the freezing compartment 21 and the refrigerating compartment 31 is usually heat-exchanged while passing through an evaporator (not shown) disposed in a circulation passage (not shown) formed on the rear wall of the freezing compartment 1. As the moisture in the air condenses on the surface of the evaporator upon contact with the evaporator, the air passing through the evaporator is in a dry state with low humidity. When the cold-dried cold air is in contact with the surface of the vegetable or fruit, the moisture of the vegetable or fruit is easily evaporated and withered.

Accordingly, it is an object of the present invention to provide a refrigerator having a vegetable room humidity control function capable of controlling the humidity of the vegetable room and storing fresh vegetables and fruits.

According to the present invention, a refrigerator having a refrigerating chamber and a vegetable compartment, according to the present invention, comprising: an atomizer disposed to spray water into the inside of the vegetable compartment; A humidity detection sensor for detecting humidity in the vegetable chamber; And a control unit for controlling the atomization device based on the detection result of the humidity detection sensor.

Here, the atomizer is preferably configured to include a spray nozzle for injecting water into the droplet state inside the vegetable chamber, a water supply pipe for supplying water to the injection nozzle, and a water supply valve for opening and closing the water supply pipe.

The atomizer is effectively an atomizer driven by an electric force.

It is preferable to further include a water storage tank disposed upstream of the atomization device to store water along the flow direction of the water supplied to the atomization device.

The water storage tank is effectively disposed in the refrigerating compartment.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.
