て面倒なものであつた。 In an air conditioner in which a baffle plate, which also serves as a fan casing and has a suction port on the surface facing the centrifugal fan, is installed around the outer periphery of a centrifugal fan disposed facing an indoor heat exchanger, Due to the structure, it is impossible to make the fan casing into an ideal shape, so the pressure balance on the suction side of the centrifugal fan becomes imbalanced, resulting in wind noise and whistling noise. As a countermeasure against this problem, conventionally, a current plate is provided on the outer periphery of the suction port of the fan casing to balance the pressure on the suction side of the centrifugal fan. However, when trying to share the fan casing with many models with different cooling capacities, the pressure balance on the suction side changes slightly depending on the model, so it is necessary to change the installation position of the rectifier plate accordingly. Conventionally, this current plate is fixed to the fan casing by screwing or welding, so the installation position must be set and fixed depending on the model, which is extremely troublesome. It was hot.

に形成されている。 This invention solves the above conventional problems,
The present invention will be described below with reference to an embodiment shown in the figure. Reference numeral 1 denotes a main body base of an air conditioner. The main body base 1 is divided into an indoor side and an outdoor side by a partition plate 4. Indoor heat exchanger 2 is installed in
On the outdoor side, an outdoor heat exchanger 3, a fan motor 5, a compressor 6, etc. are arranged. Further, a centrifugal fan 7 driven by a fan motor 5 is disposed on the indoor side facing the indoor heat exchanger 2, and on the outer periphery of the centrifugal fan 7, in combination with the partition plate 4, a An air guide plate 8 that also serves as a fan casing that forms an inner air guide path is provided. This baffle plate 8 is molded from synthetic resin or the like, and has a suction port 8a formed on the surface facing the centrifugal fan 7, and a separately formed annular bell mouth ring 9 is installed in this suction port 8a. There is. This bell mouth ring 9
has a bell mouth part 9a of the centrifugal fan 7 inside it.
However, a hook 11 for engaging the suction port 8a is integrally formed on the peripheral edge thereof, and a rectifying plate 10 for balancing the pressure on the suction side is integrally formed on one side of the outside. .

ものである。 As described above, the bell mouth ring 9, which integrally forms a bell mouth part on the inside and a rectifying plate on the outside, is rotatably attached to the suction port 8a of the fan casing of the baffle plate 8. By rotating the ring 9, the rectifier plate 10 can be easily set to the optimal position corresponding to the model, thereby making it possible to equalize the pressure balance on the suction side of the centrifugal fan. It is possible to prevent wind noise and whistling noise from occurring. In addition, since the bell mouth ring 9 can be attached by simply fitting it into the suction port 8a, there is no need to prepare fastening parts for fixing unlike conventional ones, which reduces the number of parts and simplifies the installation work. These can be implemented at low cost with an extremely simple configuration as described above.
