能になる。BEST MODE FOR CARRYING OUT THE INVENTION The inventors paid attention to the fact that dirt on a heat exchanger was concentrated within 10 mm from the tips of fins, and focused on cleaning only this portion. The indoor unit of an air conditioner has a structure in which indoor air is sucked from a heat exchanger portion through a pre-filter from a suction grill, and the heat-exchanged air is blown from an outlet. Large particles such as dust sucked from the room along with air are captured by the pre-filter. Furthermore, oil stains and dust adhere to the fins of the heat exchanger, which are exposed at the outermost positions and within 10 mm from the tips. When the air conditioner that had been used for a long period of time was disassembled and the heat exchanger was examined for dirt, dust was found near the tips of the fins. Further, the area within 10 mm from the tip of the fin was discolored brown. That is, if only the tip portion is washed to remove the oil stains adhering to the dust, almost all the stains on the heat exchanger can be removed. By removing the dirt on this part, it becomes possible to eliminate ventilation resistance due to dust, and further to save energy of the air conditioner. Therefore, a brush having a bristle length of less than 10 mm is most preferable for cleaning within 10 mm from the tips of the fins. The fins of the heat exchanger are provided with slits to improve heat exchange efficiency, and the length of the bristles is 1
If the length is 0 mm or more, the bristles of the brush are caught in the slits, which lowers the cleaning efficiency or deforms the fins to lower the heat exchange efficiency, which is not preferable. Also,
When the hair length is 10 mm or more, the hair tips stay in the inner part of the fins of the heat exchanger, making it difficult to scrub a portion 10 mm or less from the tip. It is difficult to remove oil stains adhering to the fins of the heat exchanger only with a detergent, and the stains can be effectively removed by scrubbing.

FIG. 3 is a perspective view of a cleaning tool in which the length of the bristles is less than 10 mm from the surface of the brush and the bristle tips are provided with the brush part 3 which is spread by 30 degrees or more in the vertical direction with respect to the arrangement direction of the fins of the heat exchanger. Is. The surfactant used here is not specified, but should be selected so as not to have a bad influence on the synthetic resin used in the indoor unit of the air conditioner. Further, it is not preferable that the essential oil such as hinokitiol, which has low volatility, stays in the air conditioner even after washing.

Further, the container 1 containing the detergent should not come into contact with the heat exchanger during cleaning so as not to interfere with the cleaning. It is preferable that the detergent is exuded from the root of the hair so that the detergent is always present at the tip of the hair of the cleaning tool.

る。As for the material of the bristles of the brush, in addition to nylon, synthetic fibers such as polyester, natural fibers such as pig hair, and self-supporting materials such as metal wires can be used. A relatively hard material such as nylon is preferred because it can remove dirt more easily than a soft material such as pig hair. When using a metal wire, it is preferable that the metal wire is softer than the fins of the heat exchanger because damage to the fins is small.
The brush support and the protrusion serving as the grip may be of any type, but it is cheap and easy to use made of plastics. Further, the bristle tips are spread by 30 degrees or more in the vertical direction with respect to the arrangement direction of the fins of the heat exchanger. If the spread is less than 30 degrees, the tips of the hairs do not contact the fins sufficiently when the fins are washed, resulting in poor cleaning power. Further, in the present invention, as this cleaning method, it is necessary to spread the brush so as to be perpendicular to the arrangement of the fins of the heat exchanger so that the bristle tips can rub the side surface of the fin.

好ましい。ブラシ自体は熱交換器に対して左右方向に大
きすぎないのが好ましい。左右方向に大きすぎるとブラ
シの左右端付近でブラシの毛がフィンの表面から奥へ届
く範囲が少ないため効果的に汚れを落としにくい。When bristle tips are planted on plastics, it is common to make holes in the brush support and insert a plurality of bristles into one hole. In the case of such a brush, a plurality of bristles of hair are gathered to form one brush. The direction of the hair may be different for each lump of hair.
For example, it is preferable that the hairs are fan-shaped spread over 30 degrees as a whole because the tips of the hairs scrub the surface of the fins during cleaning. The brush itself is preferably not too large in the lateral direction with respect to the heat exchanger. If it is too large in the left-right direction, it is difficult to effectively remove stains because the brush bristles do not reach from the surface of the fin to the depth near the left and right ends of the brush.

に除去することができる。FIG. 3 is a perspective view showing only the brush portion 6 of the cleaning tool for the heat exchanger according to another embodiment of the present invention in which the wire 5 made of iron or the like is used as the brush support. A brush is formed by weaving a nylon thread as the bristles of the brush on the wire 5 of the brush support. The optimum length of the nylon thread is less than 10 mm. In this case, the washing direction must be such that the tips of the hairs hit the fins of the heat exchanger as shown by the arrows in the figure. By using the cleaning tool for the heat exchanger, it is possible to effectively remove dirt on the fins of the heat exchanger.

上での滞留時間が長くなるため好ましい。Further, it is possible to compress and enclose a substance which becomes a gas at room temperature in a container for containing the detergent so that the detergent can be sprayed at the time of cleaning. In this case, as the gas to be enclosed together with the detergent, the gas used in ordinary spray such as LPG, carbon dioxide, dimethyl ether can be used. In this case, it is preferable to form bubbles of the detergent so that the detergent adheres to the fins of the heat exchanger in a foamed state because the residence time of the detergent on the fins becomes long.

At this time, if the brush is inserted to a depth of 10 mm or more, the brush is caught in the slit portion formed on the fin of the heat exchanger for increasing the heat exchange efficiency, which is not preferable. Even when the brush is not moved in parallel with the fin arrangement direction, the fin is deformed, which is not preferable.
