DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-mounted air conditioner of the type in which an indoor unit is installed above a ceiling or suspended from a ceiling surface.
The present invention relates to a mounting structure of an automatic air conditioner cleaning device for cleaning a heat exchanger contaminated with oil smoke or the like using a detergent solution.

[0002]

2. Description of the Related Art The above ceiling mounted air conditioner is particularly suitable for offices and restaurants from the viewpoint of improving heat exchange efficiency and utilizing indoor floor surfaces. However, in these places,
It is necessary to clean the oil smoke generated by smoking and cooking, since the oil smoke sticks to the heat exchanger and the heat exchange function is rapidly deteriorated. This oily stain cannot be removed without using a detergent solution. However, using a scourer or a rag to wipe off dirt would be a high-altitude operation and would not be very efficient. Therefore, a method of spraying a detergent liquid onto a heat exchanger using an injection nozzle has been used for an air conditioner of a ceiling embedded type as shown in FIG. In this method, after removing parts that hinder the cleaning operation of a ventilation panel provided on the ceiling surface and a fan (not shown) fitted to a fan motor or the like, surrounding the outer circumference of the indoor unit casing 101, the transparent panel is formed. A funnel-shaped washing liquid receiver 102 made of a vinyl sheet is vertically provided, and a detergent liquid and washing water spray nozzle 104 is inserted through a hollow hole 103 provided on a side surface of the washing liquid receiver 102. 105 in the figure is a detergent reservoir, 1
Reference numeral 06 denotes a suction pump, and 107 denotes a suction hose having the injection nozzle 104 attached to the tip. The washing liquid dripping from the heat exchanger passes through the washing liquid receiver 102 and the drain hose 108, and the washing liquid 1
Collected in 09. Further, Japanese Patent Application Laid-Open No. 4-306496 discloses a cleaning unit in which a cleaning liquid (and air) discharge nozzle and a suction nozzle are combined in an arrangement sandwiching a heat exchanger.
A technique of reciprocating left and right along a heat exchanger while holding it by hand is disclosed. On the other hand, the indoor unit 200 of the ceiling-suspended air conditioner illustrated in FIG. 13 was once removed from the ceiling surface 300, washed, and then attached to the ceiling surface again.

[0003]

However, the method of spraying the detergent liquid from the spray nozzle inserted into the bore of the washing liquid receiver is far better than the method of wiping with a rag,
It involves the danger of working at heights and requires considerable effort. Such difficulties are common to the apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 4-306496, in which the cleaning unit is reciprocated while being held by an operator by hand. On the other hand, the method of once removing the indoor unit from the ceiling surface at the time of cleaning is extremely inefficient because the attaching and detaching work requires a great deal of work. Accordingly, the applicant of the present application has proposed a complete indoor unit of a type in which a heat exchanger is provided so as to surround a fan, by completely turning an injection nozzle installed at a location where the fan is removed toward the heat exchanger. A heat exchanger cleaning apparatus capable of performing automatic cleaning has been developed, and patent applications have been filed as "Japanese Patent Application No. 5-269699" and "Japanese Patent Application No. 5-269699". However, the method of disposing the heat exchanger is not limited to the above, and two rectangular plate-shaped heat exchangers are opposed to each other with a fan interposed therebetween. Some of them are opposed in an appropriate arrangement. With respect to this type of air conditioner, the above-mentioned prior-art invention device cannot satisfactorily achieve its excellent cleaning performance. Therefore, the object of the present invention is to

A guide rail B to be mounted on a casing of an indoor unit is detachably mounted and easily and quickly mounted, and can be shared with indoor units of different models and capacities. It is to provide the mounting structure.

[0004]

In order to achieve the above-mentioned object, the mounting structure of the automatic air conditioner cleaning apparatus according to the present invention is provided in such a manner that it is detachably laid between opposed side walls 201a of a casing 201 of an indoor unit 200. A guide rail B opposed to the longitudinal direction of the heat exchanger 50, and a member F for straddling the same, and reciprocally mounted on the guide rail B,

0, and a fixing clamp 3 that is assembled on each of the left and right sides of the mounting bar 30 to hold the lower edge portion detachably.
1 and a clamping clamp 32 that is assembled in the middle of the mounting bar 30 and that detachably grips the distal end of the guide rail B. The fixing clamp 31 and the gripping clamp 32 are preferably slidably assembled along the mounting bar 30. The gripping clamp 32 is attached to the mounting bar 3.
A base member 38 slidably attached to the base member 38, a rotating member 40 connected to the member 38 via a hinge, and a state where the guide rail B is sandwiched between the two members 38, 40 is fixed. It is good to have the structure provided with the clamp fitting 41 to be made.

[0005]

A guide rail B on which the apparatus main body A of the cleaning apparatus is mounted is detachably mounted on the casing 201 of the indoor unit 200 in a state where the guide rail B is opposed to the heat exchanger 50 at a predetermined interval. Use the setting member F. The mounting bar 30, which is the main body of the straddling member F, is connected to the opposing side wall 2 of the casing.
If the lower edge portion is held along the lower edge portion of each of the fixing members 31a, and the lower edge portion is clamped by the fixing clamps 31 on both sides, the casing 201 is easily and quickly fixed to the casing 201. Next, the main assembly A of the apparatus is mounted on the guide rail B, and both ends of the guide rail B are gripped by the grip clamps 32 which are respectively mounted in the middle of the pair of mounting bars 30.
Attachment of the apparatus body A to 1 is completed very simply and quickly. Therefore, when the cleaning nozzle 13 is connected to the cleaning liquid supply device E and provided, and the device E and the reciprocating means C are operated, the main body A of the heat exchanger 50 ejects the cleaning liquid from the cleaning nozzle 13, The heat exchanger is automatically washed by reciprocating between both ends in the direction. For indoor units of different types and capacities, the fixing clamp 31 and the gripping clamp 3
2 can be easily handled by appropriately sliding each along the mounting bar 30. A patent application has been filed for the device main body A separately from the present application.
