Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an air conditioner in which an air conditioner and a heater equipped with a combustor are housed above and below in a main body case.

(Conventional technology) Conventionally, this type of air conditioner has been designed to be integrated with the indoor interior due to architectural design requirements, so even if it is equipped with an air conditioner and a heater, the main body case is not an integrated device. In addition to being shaped, it is ideally designed to have a flat surface with no irregularities, and to be installed with the back side closely against the wall. However, in order to avoid the risk of fire, heaters equipped with combustors are instructed to be installed away from walls, and drain piping for air conditioners and fuel supply piping for heaters are installed in the rear space. Generally, the entire air conditioner is installed away from the wall.

(Problems to be solved by the invention) In the air conditioner mentioned above, dirt and dust tend to accumulate between the main body case and the wall, and the drain pipe etc. are visible from the indoor side, which interferes with the architectural design of the indoor interior. This was not desirable in terms of compatibility.

However, it is also conceivable to provide a cover plate between the main body case and the wall so as to surround the rear space, or to extend the top plate and side plates of the main body case rearward to surround the rear space. However, in either case, this rear space was too large for several pipes, resulting in wasted space, resulting in a large installation space for the air conditioner.

An object of the present invention is to provide an air conditioner that can be installed in a small space without compromising its compatibility with the interior design of the room.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an air conditioner in which an air conditioner and a heater equipped with a combustor are housed vertically in the main body case.
A recess is formed by recessing the back surface of the heater storage section in the lower part of the main body case from the back surface of the air conditioner storage section in the upper part of the main body case, and a cover plate that covers the recessed part is provided on the side surface of the recessed part. It is characterized by having the following.

(Function) By forming a recessed part on the back of the heater storage part of the main body case, it is possible to use the recessed part to secure a predetermined rear space for accommodating various pipes, and also to connect the air conditioner to the cooling unit. By installing the air conditioner in close contact with the wall at the back of the storage section, it is possible to reduce the installation space for the air conditioner. Furthermore, by providing a cover plate on the side surface of the recessed part, various types of piping installed in the recessed part can be hidden, and the entire air conditioner feels like it is in close contact with the wall, making it possible to improve the interior of the room. It is possible to maintain compatibility with

(Example) An air conditioner for indoor installation in which the present invention is incorporated with a fan coil type air conditioner in the upper part and a gas warm air heater type heater in the lower part will be described.

It is divided into the air conditioner accommodating section 3 and the lower heater accommodating section 5, and the air conditioner accommodating section 3 is provided with a coil 7 so as to cross the air guide path 19 of the accommodating section 3. An outgoing pipe P1 and a return pipe P2 are connected to the coil 7 for circulating refrigerant from the outside, and while circulating the refrigerant in the coil 7, a cold air fan 8 is driven to draw indoor air from the suction port 16 to the coil 7. The air conditioner 4 is constructed so that the air passes through the air to exchange heat, and blows the air into the room from the cold air fan 8 through the air outlet 14 for cold air. Further, water droplets condensed on the surface of the coil 7 are received by a drain pan 20 provided at the lower part of the coil 7, and are led from the drain pan 20 to a drain pipe P3 and drained to the outside.

In addition, a combustor 9 is provided in the air guide path 21 in the heater housing section 5, and a gas pipe P4 is connected to the combustor 9 to supply gas from the outside via a controller 22. At the same time, the gas is combusted in step 9, and the hot air fan 10 is driven to suck indoor air into the air guide path 21 from the suction port 16, and from the hot air fan 10 through the hot air outlet 17 together with the combustion hot air. The heater 6 is configured to blow air into the room.
