- Showcase, freezer, refrigerator, etc. are devices for storing food at a low temperature so as to prevent the food from decaying, use the heat of vaporization of refrigerant such as Freon, and perform a heat exchange in the condenser to obtain the heat of vaporization. Here, in order to increase the efficiency of the heat exchange, a twisted condensing tube and a plurality of heat exchange fins formed on the condensing tube are blown with by cold air by a ventilating fan.
- The condenser usually collects a lot of debris and small stuffs such as dust from outside due to the ventilation, which is for increasing efficiency of condenser, and such dusts causes the performance of heat exchange decreased and the compressor break down.
- In order to improve such problems, a device of removing bad smell from air-conditioner was suggested in the Korean Patent Application 10-0218460, which forms a spraying tube connected to a medicine container on a top portion of the vaporizer and having a nozzle, and cleansing was performed through killing germs by a medicine mixed with cleaning water and cleaning by spraying of the cleaning water, by spraying the cleaning water in the medicine container by closing and opening valve by control signals.
- However, the spraying of cleaning water had problems that the spraying power of the sprayer is weak, and it could not spray the cleaning water in a spraying power and into between the heat exchange fins, which can remove dust stuck strongly or between the narrowly-spaced heat exchange fins.
- Additionally, an air-filter automatic cleaning device in another Korean Patent Application 10-1997-0047263 had a filter wired in an endless track form connected to a cleaning brush driven by a driving motor engage with a condenser, such that the filter rotated and cleaned dust off the surface of the condenser and increased the efficiency by spraying cleaning water from the brush, facilitating the cleaning.
- The filter in such a structure performed just cleaning of the surface of condenser through friction, but could not clean and remove dust stuck between the heat exchange fins of the condenser.
- Also, since the filter of endless track type was prone to be worn out easily and cut out frequently, it could not be used for an extended time period, the filter formed with textile fabric or unwoven fabric was always present together with moisture due to the cleaning water, such that it provided an environment of bad smells and dirtiness due to inhabitation and multiplication of bacterial germs enabled by the moisture.

- As shown in the perspective view of
FIG. 1 , the cross-sectional plan view ofFIG. 2 , and the perspective front view ofFIG. 3 , the present invention is to provide an apparatus, which cleans dust and debris off thecondenser 100 for the showcase, freezers, or refrigerator, in which air blown from a ventilating fan to thecondenser 100 for heat exchange in a process of refrigerant compressing has dust and debris stuck in theheat exchange 101 of thecondenser 100, reducing the efficiency of heat exchange, which must be removed periodically. - This cleaning can be done periodically manually or by a controlling device (not shown), and the driving motor M is operated by supplying power according to the control. Therefore, the
wire winch 17 and the cleaningbrush 18 fixed to the drivingaxle 16 are made to rotate by the rotation of the drivingaxle 16. - Such a rotation winds the
wire 22 wound at thewire winch 17 in a direction of rotation, for example, the top portion of thewire 22 and unwinds the other side, such that an upward-force is formed in thewire winch 17, and theentire driving axle 16, the deliveringplate 15 penetrating the drivingaxle 16, and the driving motor M fixed to the deliveringplate 15 move upward, and the deliveringroll 14 engaging the deliveringplate 15 is guided by theguide rail 11 formed in theguide frame 10, so as to move up and down precisely. - The cleaning
brush 18 rotated by therotating driving axle 16 moves upward while rotating, and slip-rotates against thecondenser 100 and theheat exchange fins 101 stuck with dust and debris from the air from the ventilating fan, so as to clean them off. - When reaching the top limit point performing the above jobs, the cleaning
brush 18 touches thelimit switch 23 formed in thewing 12 of theguide frame 10, and then thelimit switch 23 controls the electrical power and reverses the rotation of the cleaningbrush 18, from one direction to the other direction. - Such a reverse rotation is applied to the driving motor M and the driving
axle 16 together, winding the bottom portion ofwire 22 and unwinding the top portion ofwire 22 at thewire winch 17, such that thewire winch 17 moves downward, and if reaching the bottom limit point and touching thelimit switch 23 then the rotation direction of the driving motor M is changed. - The cleaning
brush 18 that is operated by the up-down movement by reciprocation and the rotation by the drivingaxle 16 removes the dust and debris stuck in theheat exchange fins 101 of the cooler continuously, and increases the efficiency of heat exchange of the cooler due to the thorough cleaning and repeated cleaning. - In another embodiment of the invention as shown in
FIG. 4 , the deliveringplate 15 is guided by theguide rail 11 of theguide frame 10 fastened to both sides of thecondenser 100 and reciprocates, the driving motor M is fixed to the deliveringplate 15 and thepinion 30 is fixed to the drivingaxle 16, and therack 31 is formed inside the fixingpanel 20 engaging theguide frame 10 so as to engage thepinion 30. - Therefore, the
pinion 30 that is rotated by the rotation of the driving motor M reciprocates along therack 31 and the cleaningbrush 18 installed in the drivingaxle 16 which moves by such a rotation rotates so as to clean the dust and debris off thecondenser 100 and theheat exchange fins 101 through such up-down movement and rotation. - The cleaning
brush 18 that rotates and reciprocates according to the invention cleans the dust and debris collected at thecondenser 100 and theheat exchange fins 101 from the air blown by the ventilating fan in a a compressing process of refrigerant circulating through the compressor and thecondenser 100. - The cleaning
brush 18 may be made in a form of brush or in a form of pad of unwoven fabric. And, the device may further comprise a controller for providing a function of automatic cleaning at predetermined time and date or the cleaning may be started manually. - While the invention has been shown and described with reference to different embodiments thereof, it will be appreciated by those skilled in the art that variations in form, detail, compositions and operation may be made without departing from the spirit and scope of the invention as defined by the accompanying claims.
