Abstract

(57) [Summary] [Purpose] The larger the size of the heat exchanger in the indoor unit of the separation type air conditioner, the greater the amount of heat exchange, the higher the capacity, and the more energy saving and noise reduction becomes possible. However, since the external dimensions of the indoor unit main body cannot be increased due to the limitation of the installation location of the air conditioner, it is an object to expand the area of the heat exchanger as much as possible in order to improve the capacity. [Structure] The structure is such that the connection pipe welded to the heat exchanger of the indoor unit of the air conditioner is wound around the space sandwiched between the partition plate and the electrical component box on the side of the air flow path to wrap the heat insulating material. . By wrapping the insulating material around the connecting pipe and moving the part with the larger diameter to the rear side of the base, and by arranging it vertically near the partition plate of the air duct, the space between the heat exchanger and the electrical equipment box can be improved. spread. It is characterized in that the length of the heat exchanger in the longitudinal direction can be increased in the increased space to increase the area of the suction surface of the indoor air and improve the heat exchange performance.

[Industrial applications]

 The present invention relates to an air conditioner, and more particularly to the structure of an indoor unit.

[0002]

[Prior art]

 An indoor unit of an air conditioner, comprising: a chassis main body; and a front panel detachably attached to the chassis main body, wherein a heat exchanger and a blower are installed in the chassis. Is a pair of side plates for mounting the heat exchanger to seal the air passage and a partition plate for protecting the electrical equipment box mounted on the chassis body, and the heat exchange is performed in the space between the side plate and the partition plate. The connection pipe connected to the air conditioner was covered with a heat insulating material to prevent dewfall, and it was started up along the rear surface of the chassis body and connected to the heat exchanger, but the heat exchange required to improve the capacity of the air conditioner There was a problem because the area of the vessel could not be expanded.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object of the present invention is to provide a structure capable of enlarging the area of a heat exchanger so as to improve the capacity.

[0004]

[Means for Solving the Problems]

 The present invention has an enclosure that includes a chassis body and a front panel that is detachably mounted in the direction of the chassis body, and has a heat exchanger and a blower installed in the enclosure. In the indoor unit, the chassis body is provided with a pair of side plates that form the air passage by mounting the heat exchanger and a partition plate that protects an electrical equipment box mounted on the chassis body. The side plate on the side is extended in the direction of the partition plate by providing a crank-like step, and the connection pipe wrapped with heat insulating material for connecting to the heat exchanger is started up along the rear surface of the chassis body and the side plate. It is characterized in that it is bent in the direction of the partition plate, the heat insulating material is removed from the bent portion, and the heat insulating material is arranged in a space narrowed to reach the connection portion along the partition plate.

[0005]

[Action]

 By providing a step on the side plate, moving the pipe wrapped with the heat insulating material to the rear, and arranging the pipe from which the heat insulating material is removed, the area of the heat exchanger can be expanded to the width of the step on the side plate.

[0006]

【Example】

 An embodiment of increasing the area of a heat exchanger of an air conditioner according to the present invention will be described below with reference to FIGS. 1 and 2. An indoor unit of an air conditioner has a casing 1 composed of a chassis body 2 and a front panel 3 which is detachably attached to the chassis body 2, and a heat exchanger 4, a blower 5, and an electric device are provided in the casing 1. It is composed of a storage unit 6 for the product box. The chassis body 2 is partitioned by a pair of left and right side plates 8 to which the heat exchanger 4 is attached and which seals the air passage 7 and a partition plate 9 which protects the storage part 6 of the electrical equipment box. A groove 10 for receiving condensed water is provided below the lower end of the heat exchanger 4, and is connected to a drain port 11 provided at the right end. A connection pipe 12 that circulates the refrigerant from the outdoor unit is inserted from the lower part of the chassis body 2 into the gap formed by the side plate 8 and the partition plate 9 and is welded and arranged on the side surface of the heat exchanger 4. .

Here, the side plate 8 on the partition plate 9 side is extended in the direction of the partition plate 9 by forming a step in a crank shape, and the connecting pipe 12 around which the heat insulating material 13 is wound to prevent dew condensation is connected to the chassis. Start up along the rear surface of the main body 2 and the side plate 8, bend the connecting pipe 12 toward the partition plate 9 at a position higher than the connection with the heat exchanger 4, and remove the heat insulating material 13 at the end of the bend. Except for this, it is bent again along the partition plate 9 in the direction to reach the heat exchanger 4, and is connected to the heat exchanger 4. By thus moving the connecting pipe 12 wound with the heat insulating material 13 backward and arranging the connecting pipe 12 in the form of a bare tube in the space narrowed by the expansion of the side plate 8, the width of the expanded side plate 8 is reduced. The right end of the heat exchanger 4 can be extended and extended.

[0008]

[Effect of device]

 The expansion of the suction area of the heat exchanger made possible by the present invention increases the amount of suction air and improves the capacity of the air conditioner.
