DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a piping structure of an air conditioner for a bathroom unit in which a blow-out port and a suction port are inserted into a ceiling from below so as to face the ceiling of the bathroom unit. What you want to do.

[0002]

2. Description of the Related Art Recently, a bathroom unit has a ventilation device in the bathroom during bathing, a dryer for drying the bathroom after bathing and a bathroom as a drying room for laundry, and a sudden temperature decrease of a bather. In order to avoid a change, there is an air conditioner provided with a heater for pre-heating the bathroom and an air conditioner having exhaust of humid air.

[0005] More specifically, as shown in FIG. 5, a main pipe M is supplied from a feeder H outside a bathroom unit Y to a hot water circulation pipe (not shown) in a casing of an air conditioner A for a bathroom unit. A radiating fin is provided on the hot water circulation pipe in the body, and a circulation fan (sirocco fan) is provided near the hot water circulation pipe to supply hot air into the bathroom. Separately, a ventilation fan (sirocco fan) is provided to exhaust the humid air in the bathroom to the outside. When heating the bathroom, the ventilation fan is stopped, hot water is supplied, and the circulation fan is operated. When drying the bathroom or drying the laundry, warm air is supplied to the bathroom by operating the circulation fan while supplying warm water while exhausting the air with the ventilation fan. To ventilate, the supply of hot water is stopped, the circulation fan is stopped, and the ventilation fan is operated to discharge steam-containing air in the bathroom through the duct to the outside. When the bathroom is ventilated at the time of bathing, the supply of hot water may be stopped, and then the ventilation fan and the circulation fan may be operated.

The casing of the air conditioner A has a flat box shape, is provided with an exhaust opening on one side, and an exhaust elbow for connecting a fan to a duct (shown by imaginary lines) communicating outdoors. A pipe is attached, and two connection ports (hereinafter, pipe connection ports) to the hot water circulation pipe inside the housing are provided on the same side surface at the top and bottom. The air conditioner A is fitted into an opening provided in the ceiling of the bathroom unit Y from the inside and temporarily fixed, and is fixed so that the air outlet / inlet faces the ceiling of the bathroom unit Y. Drying bar B is passed to the upper part of the bathroom.

[0005] This is because it is convenient for construction to provide the exhaust opening for connecting to the duct and the connection port to the hot water circulation pipe up and down on the same side surface of the housing. That is, after assembling the bathroom unit Y including the air conditioner A at a predetermined position in the house, open the ceiling inspection opening of the bathroom unit Y at the end of the construction period, look into the bathroom unit Y, connect the hot water piping, and perform electrical wiring,
Finally, the exhaust duct connected to the outdoor and the exhaust elbow pipe attached to the exhaust opening are connected by a duct coupling. As described above, since the connection work is performed from the ceiling inspection port, it is desirable that the connection surface be close to the ceiling inspection port side from the viewpoint of workability.

[0006] Further, in terms of functional design, the upper and lower positions are as follows. First, the exhaust duct leading to the outside of the bathroom is above the space for containing the bathroom unit Y, and the hot water passes from the outside of the bathroom unit Y to the outside through the outer surface and is close to the floor. This is because the piping is connected so as to be connected to the installed water heater H. In addition, in the casing of the air conditioner A, fins are provided in the hot water pipe, and air heated in the bathroom is blown in by a fan for drying and heating, so that the exhaust opening is inevitably upper, and the hot water circulation pipe is This is because it is arranged at the lower part.

[0007]

Heretofore, as one means for connecting to a hot water circulation pipe, a hot water elbow pipe has been attached to the connection port, and the connection port has been turned in a direction parallel to the side surface of the housing. The connection was made to the main pipe M via a relay pipe which is not used. This is always performed when the air conditioner A is installed in the case of the bathroom unit Y having the vaulted ceiling shown in FIG. In other words, the air conditioner A is fixed to a flat portion avoiding the arch-shaped portion. This is because the connection to the main pipe M from the water heater H must be made unless the hot water elbow pipe E is inserted into the connection port and the end of the connection port is not parallel to the side surface of the housing.

[0008] In addition, since two hot water elbow pipes E having the same length have been used in the past, one of the hot water elbow pipes is directed upward, for example, above the other hot water elbow pipe to avoid collision. (See FIG. 6), it was necessary to change the direction and insert. Therefore, the main pipe M cannot be directly connected because the pipe end positions are slightly different, and a specially prepared relay pipe with a changed length has to be connected to the main pipe M via this relay pipe. . That is, in the conventional connection of the air conditioner A to the hot water circulation pipe, since the hot water elbow pipe E has the same length, it is unnecessary to prepare a length up to the main pipe M by using a relay pipe or the like. And the possibility of water leakage is increased by increasing the number of pipe connection points.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in piping in the conventional air conditioner A. A relay pipe is not required, and the main pipe M is connected to the elbow pipe E. An air conditioner A capable of directly connecting the air conditioner is provided.
