Abstract: A dust cleaning device for condenser of cooler is provided, which can cleanse dust and other undesirables attached to the heat exchange fin due to wind blowing for increasing efficiency of the condenser performing liquifying of refrigerant in showcase, freezer, refrigerator, etc. Since the dust from outside is attached to the condenser due to ventilation and they become one of reasons for compressor failure, the device is configured to clean the heat exchange fin of the condenser periodically, in which a wire winch and a cleaning brush is connected to a driving axle of a driving motor such that the cleaning brush performs up-and-down motion and rotation with a power of the driving motor and cleans the heat exchange fin. In other structure, pinion and rack can be connected to the driving axle to perform the up-and-down motion. The cleaning brush is made of textile or unwoven fabric.

Abstract: A defrost fan control device for a refrigerator is provided. The device comprises a container, a heat exchanger, a chamber, a suction pump, a condensate spraying device, an evaporation coil, and a blower. The suction pump is for sucking up the condensate from the container. The condensate spraying device is for spraying the condensate sucked up by the suction pump within the chamber. The evaporation coil is disposed around the condensate spraying device such that the condensate from the suction pump lands on an inner surface of the evaporation coil and evaporates the condensate. The blower is for inducing air flow within the chamber, whereby the evaporated condensate is exhausted from the chamber.

Abstract: The present invention provides systems and methods of retrieving the pages according to the quality of the individual pages. The rank of a page for a keyword is a combination of intrinsic and extrinsic ranks. Intrinsic rank is the measure of the relevancy of a page to a given keyword as claimed by the author of the page while extrinsic rank is a measure of the relevancy of a page on a given keyword as indicated by other pages. The former is obtained from the analysis of the keyword matching in various parts of the page while the latter is obtained from the context-sensitive connectivity analysis of the links connecting the entire Web. The present invention also provides the methods to solve the self-consistent equation satisfied by the page weights iteratively in a very efficient way. The ranking mechanism for multi-word query is also described. Finally, the present invention provides a method to obtain the more relevant page weights by dividing the entire hypertext pages into distinct number of groups.

Abstract: A refrigerator comprises an enclosure that is cooled below a predetermined temperature, a refrigeration circuit that keeps the temperature of the enclosure below the predetermined temperature, a door that provides access into the enclosure and a pressure equalizing device that equalizes the pressure inside the enclosure with the pressure outside the enclosure. The pressure equalizing device comprises a communication path that fluid-communicates the inside of the enclosure with the outside of the enclosure, and a valve device that opens or closes the communication path. The valve device opens the communication path when the air pressure outside the enclosure is greater than the air pressure inside the enclosure by a predetermined value. The valve device comprises a pivoting plate that is pivoted around a horizontal axis, and an opening that is open to air outside the enclosure. The pivoting plate covers the opening.
