Description
BACKGROUND OF THE
Unless otherwise indicated herein, the description set forth in this identification section is not prior art to the claims of this application and is not to be construed as prior art as described in this identification section.
A large refrigerator is a facility for keeping foods, agricultural products, livestock products, aquatic products, etc., at a low temperature, for example.
A large refrigerator generally includes a condensing unit that includes a compressor and a condensation heat exchanger integrally to circulate the refrigerant to form a refrigerating cycle and a unit cooler that generates cold air required for refrigeration or freezing through heat exchange between the inside air and the refrigerant, .
A unit cooler applied to a large refrigerator includes a housing, an evaporation heat exchanger provided inside the housing, a blowing fan installed on one side of the housing, and a terminal block for forming internal wiring such as various electric parts in the housing. The evaporation heat exchanger includes a refrigerant tube arranged in the housing, and a plurality of heat-absorbing fins are provided on an outer surface of the refrigerant tube.
In the unit cooler, the refrigerant is circulated through the condensation heat exchanger and the evaporation heat exchanger by the forced circulation force by the compressor. The air sucked by the blowing fan to pass through the evaporation heat exchanger is supplied to the evaporation heat exchanger to heat the refrigerant, So that the internal temperature of the large refrigerator is cooled to a predetermined temperature.
Meanwhile, in the unit cooler, the moisture contained in the indoor air is condensed on the evaporation heat exchanger, in particular, on the heat absorbing fin in the course of heat exchange between the room air and the evaporation heat exchanger, thereby generating frost.
Such frost causes problems such as increase of internal temperature, decrease of current required, increase of required power due to decrease of evaporation pressure and suction pressure, increase of discharge air temperature, decrease of air volume and poor heat transfer function.
A defrost heater for removing frost is installed in the housing of the unit cooler in order to prevent the aforementioned problem caused by the occurrence of frost. Such a defrost heater is formed in a structure in which a heating coil is embedded in a cylindrical case.
However, the conventional defrost heater is not operated only when a frost is generated, but is set to operate at a constant time by a timer system, which is disadvantageous in terms of efficiency.
In order to improve the defrosting efficiency, an infrared sensor for red-on-infrared sensing is recently used in order to detect whether or not the infrared sensor is turned on and off according to the light emission and the reception of the infrared ray. Such an infrared sensor for the red image sensor is disclosed in Korean Patent Publication No. 10-1402705 (Apr. Published in Korean Patent Application No. 10-2011-0024428 (published on Mar. 3, 2011), and Korean Patent Laid-Open Publication No. 10-2013-0036858 (published on April 15, 2013).
Infrared sensors applied for infrared detection usually have a service life of about 7 years, so they must be replaced regularly after a certain period of time after installation of a large refrigerator. However, in reality, the replacement of defective infrared sensor or maintenance of defective infrared sensor is not performed properly, and defrost efficiency is rapidly deteriorated due to malfunction related to defrost.
Further, in the case of a conventional large-sized refrigerator, even if a harmful gas such as ethylene gas is generated from some articles being refrigerated, separate ventilation measures can not be taken immediately, so that oxidation or corruption of the entire article in refrigerated storage can be promoted There was also a problem.
In addition, in the case of a conventional large-sized refrigerator, a urethane foam panel foamed with Freon gas is applied for insulation of a wall, which is not environmentally friendly.
The present invention provides a multi-function power saving type large-sized refrigerator which can maintain the defrosting efficiency semi-permanently without periodically replacing the redemption sensor, and can keep the article refrigerated for a long time in a fresh condition.
The present invention also provides a multifunctional power saving type large refrigerator which can be environmentally friendly.
Further, it is obvious that the present invention is not limited to the technical problems described above, and another technical problem may be derived from the following description.
According to an embodiment of the present invention, there is provided a refrigerator comprising: a refrigerator body having a storage space formed therein and having a door on one side; A condensing unit provided outside the refrigerator body; The evaporation heat exchanger is installed in the storage space of the refrigerator main body and is connected to the condensing unit in a refrigerant circulation manner and a plurality of heat absorbing fins are protruded so as to be spaced apart from each other. A unit cooler having a blowing fan for cooling the blower; Wherein a pair of elastic legs to be fitted between the heat absorbing fins of the evaporation heat exchanger are formed on both sides of the elastic legs, and at the ends of the elastic legs, mutually conductive contacts are formed when the elastic legs come close to each other, Detection sensor; A defrost heater installed on the evaporator / heat exchanger side of the unit cooler and generating heat according to a sensor signal of the redemption sensor; Ventilation means installed in the refrigerator body for sensing and forcibly discharging noxious gas in the storage space; And a controller installed in the refrigerator body and controlling operation of the condensing unit, the unit cooler, the enemy image sensor, the defrost heater, and the ventilation means.
In addition, the unit cooler may include an ionizer for providing negative ions to the air volume by the blowing fan.
Further, the redemption sensor may be formed in a "U" shape by the pair of elastic legs.
According to an embodiment of the disclosed subject matter, the defrost efficiency can be maintained semi-permanently without replacement of a redemption sensor having a predetermined service life.
In addition, immediate ventilation of harmful gas and inhibition of mold or harmful bacteria caused by anion can keep the article in a fresh condition for long-term refrigeration.
In addition, the insulation of the wall can be made eco-friendly.
