DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a case where the air-conditioner cleaning method of the present invention is applied to a ceiling-mounted air conditioner will be described in detail with reference to the drawings.
As shown in FIG. 1, first, the suction face 2 of the air conditioner main body 1 is opened, the drainage tube 4 is attached to the drain cock 3, and the wastewater remaining in the air conditioner is discharged into the waste collection container 5. Thereafter, a vinyl cover 6 that covers the entire periphery and the lower surface of the air conditioner body 1 is fixed to the ceiling. The vinyl cover 6 is provided with through holes 8a and 8b through which the drainage tube 4 and a cleaning liquid supply pipe 7 described later are disposed.
[0011]
Further, a vaporizing humidifier 9 for vaporizing the cleaning liquid stored therein is installed in the vicinity of the waste collection container 5, and the cleaning liquid vaporized by the vaporizing humidifier 9 is passed through the cleaning liquid supply pipe 7. Supply to the opening of the air conditioner body 1. At the same time, the air conditioner is blown and intermittently cooled (set temperature is about 20 ° C.). For example, the air blowing operation for 10 minutes → the cooling operation for 2 minutes is repeated 3 to 4 times.
[0012]
By operating in this way, the vaporized cleaning liquid uniformly enters the entire fan fin 10 of the air conditioner and the coil fins of the heat exchanger 11, and is immediately cooled by the cooling operation at that time to cause dew condensation. As a result, since the cleaning liquid uniformly adheres to the entire interior of the coil fin, which has conventionally been difficult to clean, the cleaning effect can be exerted over the details of the coil fin. Then, the condensed cleaning liquid is discharged to the waste collection container 5 through the drainage tube 4 attached to the drain cock 3. The method for discharging the condensed cleaning liquid may be a natural discharge by gravity or a suction method using a suction pump.
[0013]
Subsequently, the rinsing liquid is put into the vaporizing humidifier 9, and the rinsing liquid is vaporized in the same manner as described above, and supplied to the opening of the air conditioner main body 1 through the cleaning liquid supply pipe 7. At the same time, the air conditioner is blown and intermittently cooled (set temperature is about 20 ° C.). For example, the air blowing operation for 10 minutes → the cooling operation for 2 minutes is repeated 2-3 times. By such an operation, the rinsing liquid is condensed, and the condensed rinsing liquid is discharged to the discharge collecting container 5 through the drainage tube 4 attached to the drain cock 3. After the rinsing process is completed, the inside of the air conditioner is dried. In addition, although the inside of an air-conditioner can be dried only by a ventilation operation, a drying process can be performed in a shorter time by performing a heating operation.
[0014]
As described above, according to the method for cleaning an air conditioner of the present invention, the details of the coil fins can be cleaned by evaporating the cleaning liquid and sending it into the air conditioner. There is no need to remove parts or electrical parts, and the cleaning operation is greatly simplified.
In addition, it is not necessary to remove the electrical parts, and it is not necessary to turn off the air conditioner during the cleaning process. The cleaning liquid that has entered the fins can be easily condensed. Furthermore, since the condensed cleaning liquid is naturally discharged by its gravity, it does not have to be sucked using a suction pump, and the equipment necessary for the cleaning operation is simplified.
[0015]
(Other embodiments)
In addition, this invention is not limited to embodiment mentioned above, The various aspects as shown below are also possible. That is, the specific shape of each member, the mounting position, and the method can be changed as appropriate. Further, the present invention can be applied not only to a ceiling-mounted air conditioner but also to a wall air conditioner, a window air conditioner, and a packaged air conditioner. The vaporizing humidifier may be of any type, such as a steam humidifier or an ultrasonic humidifier.
[0016]
In addition, the cleaning agent applied to the present invention is not particularly limited and may be liquid or solid as long as its form can be vaporized. However, a strong alkaline cleaning agent is used for oil stains and the like. It is preferable to use electrolytic functional water for normal soiling from the viewpoint of ease of rinsing and low pollution. The electrolyzed functional water is obtained by mixing a small amount of NaCl in water and electrolyzing it, and is known to have better cleaning ability than ordinary water. In addition, it contains no chemicals that are harmful to the human body or the environment, and is a highly safe cleaning agent.
[0017]
When a strong alkaline cleaning agent is used as the cleaning agent, it is desirable to use a strongly acidic neutralizing agent as the rinsing liquid in order to prevent corrosion of the coil portion and the like. Further, when electrolytically functional water is used as the cleaning agent, water can be used as the rinsing liquid, so that the cleaning operation becomes simpler.
[0018]
Further, a filter 12 for filtration is provided in the waste collection container 5 to remove dust and dirt in the cleaning liquid collected in the waste collection container 5, and the cleaning liquid after the removal is supplied to the vaporizing humidifier 9 again. It can be reused. This is because most of the dirt adhering to the fin portion of the air conditioner is dust or dust, and the cleaning power of the cleaning liquid itself is not reduced. If the air conditioner is heavily contaminated with oil and the cleaning liquid discharged to the waste collection container 5 is very dirty, it is desirable to replace the cleaning liquid appropriately.
[0019]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a cleaning method for an air conditioner for a room that can allow a cleaning agent to enter the fins and clean the inside of the fins uniformly.
