Abstract

PROBLEM TO BE SOLVED: To prevent generation of fluid noise in a cross flow blower, which is caused by the lowering of flow rate performance which results from increasingly strong collision when leaking airflow and air flowing in from a heat exchanger join together, while permitting a suction flow to flow smoothly at the end portion of a stabilizer. SOLUTION: The distance between a cross flow fan 8 and an end portion of a stabilizer 10 is gradually increased beginning from a tip 13 of the end portion toward a point 14 of the end portion 12. The end portion 12 of the stabilizer 10 is curved toward a heat exchanger 7. A suction flow from the heat exchanger 7 is smoothed along the curved portion. A recess 15 serving as a resonant type silencer is provided at a back surface of the tip 13 of the stabilizer 10.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first and second embodiments, a tip end of a stabilizer extending in a rotation direction of a cross flow fan has a tip which minimizes a distance from the cross flow fan, and the tip end is formed from the tip. Increasing the distance between the tip and the cross flow fan gradually toward the tip of the tip,
A recess is provided on the substantially rear surface of the tip. With this configuration, it is possible to reduce drift and turbulence when the suction flow from the heat exchanger and the leak flow from the outlet (flow in the rotation direction of the fan from the stabilizer tongue) merge at the stabilizer tip. Further, by providing a recess on the back surface of the protruding end, it is possible to prevent a rapid increase in the suction flow from the heat exchanger and smooth the flow. In addition, the recessed portion functions as a volume of the resonance type silencer, and noise can be reduced.

FIG. 1 is a transverse sectional view of a first embodiment of the present invention, FIG. 2 is an enlarged view of a portion α, and FIG. 3 is a perspective view of the same. The general flow and configuration will be described.
In addition, room air is sucked from the suction port 1 provided in the main body frame 5 and passes through a detachable air filter 6 and a heat exchanger 7 provided along the inner surface of the front cover 4 to form a cross flow. It is sucked into the fan 8. Further, the air sucked into the cross flow fan 8 passes through the air passage 3 formed by the rear guider 9 provided on the back of the cross flow fan 8 and the stabilizer 10 provided on the front of the cross flow fan 8. It is released from the outlet 2. The outlet 2 has a wind direction blade 11 so that the wind direction can be adjusted. At the tip of the stabilizer 10 extending in the rotation direction of the cross flow fan 8, there is a tip 13 having the shortest distance from the cross flow fan 8, and the tip 13 gradually moves from the tip 13 toward the tip 14 of the tip 12. 12 and the distance between the cross flow fan 8 and the stabilizer 1
The curved portion 15 is curved toward the heat exchanger 7 from the recess 15 of the front end portion 12 toward the point 14. The suction flow (arrow A) from the heat exchanger 7 can be made smooth along this curved portion. This is thought to be due to the fact that the depression 15 at the tip end portion 12 of the stabilizer 10 prevents a sudden increase in speed and suppresses an increase in disturbance. Furthermore, it is possible to reduce drift and turbulence at the time of merging with the leakage flow from the outlet 2 (flow in the rotation direction of the fan from the stabilizer tongue portion 10a: arrow B), thereby improving flow performance. In addition, the depression 15 provided on the back surface of the protruding end 13 of the stabilizer 10 causes the region of the depression to have a similar effect to the volume of the resonance type silencer. That is, the noise of the fluid noise generated in the vicinity can be reduced by the function of the resonance type silencer.

As is apparent from the above description, the present invention has the tip of the stabilizer which extends in the rotation direction of the cross flow fan and has a tip which minimizes the distance from the cross flow fan. The distance between the front end and the cross flow fan is gradually increased toward the tip of the portion, and the front end of the stabilizer is provided with a depression on the substantially rear surface of the protruding end where the distance from the cross flow fan is shortest. The depression prevents a rapid increase in the flow of the suction flow from the heat exchanger, suppresses an increase in turbulence, and makes the flow smooth. In addition, the flow performance can be improved by reducing the drift and the turbulence when merging with the leakage flow from the outlet. In addition, the depression provided on the back side of the stabilizer tip allows the depression area to have a similar effect as the volume of the resonance type silencer. That is, the noise of the fluid noise generated in the vicinity can be reduced by the function of the resonance type silencer.
