Benefits of technology
[0010]The present invention has been made in view of the above-mentioned problems, and an aspect of the invention is to provide a passage switching valve
Problems solved by technology
However, in the passage switching valve, when the first and second outlet ports are opened so that the refrigerant flows to the two outlet ports, since the refrigerant is concentrated more to one of the outlet ports than the other, the refrigerant is not uniformly distributed to the outlet ports.
In the case where the passage switching valve is even slightly inclined when the passage switching valve is mounted, difference in height between the outlet ports is generated so that the problem may become serious.
However, in such a method, since the step motor is to be continuously operated in order to alternately open and close the first and second outlet ports, energy loss is large and the lifespan of the step motor may be shortened.

A passage switching valve for maintaining a plurality of outlet ports to be opened and for uniformly distributing a fluid to the outlet ports and a refrigerator employing the same are disclosed. The passage switching valve includes a housing having an inlet port and a plurality of outlet ports, an opening and closing member for opening and closing the outlet ports, and a driving device for operating the opening and closing member. The outlet ports are provided in a lower position than the inlet port. A collecting portion is formed by providing a recess in the bottom portion of the housing such that a fluid can be collected and the outlet ports are formed in the collecting portion.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 2006-0030165, filed Apr. 3, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a passage switching valve and a refrigerator employing the same, and more particularly, to a passage switching valve for uniformly distributing a fluid to a plurality of outlet ports and a refrigerator employing the same.[0004]2. Description of the Related Art[0005]In general, a passage switching valve is commonly used for changing or opening and closing a refrigerant passage in a refrigerator or an air conditioner. For example, the passage switching valve may be used when refrigerant is selectively supplied to any one of evaporators or is supplied to all evaporators in a refrigerator including a plurality of the evaporators.[0006]A passage ...
