スイッチ６側からスイッチ５側に切換える。FIG. 4 is a cross-sectional view of the air outlet of a ceiling-suspended or wall-mounted air conditioner disclosed in, for example, Japanese Patent Publication No. 57-15296. Reference numeral 1 denotes an air outlet, and 2 represents a blade that is provided within the air outlet l and rotates around a shaft 3 to change the blowing direction of the airflow from the air outlet 1. 5 to 7 show a drive mechanism for the blade 12, and the shaft 3 of the blade 2 is connected to an electric motor 4. 5
．． 6 is a switch that is turned on and off by each blade 2;
It's usually closed. When the switch 6 is closed, the electric motor 4 rotates clockwise, and when the switch 5 is closed, the electric motor 4 rotates counterclockwise. Reference numeral 7 denotes a changeover switch connected to rotate the shaft 3 of the wing [2, which is switched by a relay 8 and selectively connected to the switch 5.6. Reference numeral 9 denotes a thermistor (temperature-sensitive element) that detects, for example, the temperature of the air outlet, and activates the relay 8 in accordance with the temperature of the air outlet. When the blowing temperature is high, the relay 8 operates to switch the changeover switch 7 from the switch 6 side to the switch 5 side.

回転し、スイッチ６の係合子６ａを押して接点を開く、
このため、電流は流れなくなり、電動機４は停止する。Next, the operation will be explained. If the hot water level is low, relay 8
does not work, and the selector switch 7 is in the position shown in FIG. 7, that is, in a connected state with the switch 6. Current from source 20 therefore flows through switch 6, causing motor 4 to rotate clockwise in FIG. open,
Therefore, current no longer flows and the electric motor 4 stops.
即ち、羽根２の下流側が上を向いた状態で停止する。That is, the blade 2 stops with the downstream side facing upward.
次に、吹出温度が高（なった場合は、サーミスタ９が温

た位置で停止する。温度が再び低くなった場合には切換
スイッチ７が再び切換ねり、前述と同様にして羽根２の
下流側が上を向く。Next, when the blowout temperature becomes high (when it becomes high), the thermistor 9 detects the temperature, the relay 8 operates, and the changeover switch 7 is switched to the switch 5 side and connected state. Therefore, the current flows toward the switch 5. , the electric motor 4 rotates counterclockwise,
When the blade 12 pushes the engager 5a of the switch 5, the contact opens and the motor 4 stops. That is, it stops at a position where the downstream side of the blade 2 faces downward. When the temperature becomes low again, the changeover switch 7 is switched again, and the downstream side of the blade 2 faces upward in the same manner as described above.

The position of the blade 2 is changed to control the direction of the blown air current, and the position of the blade 2 is detected by opening the contact of the switch 5.6, and the electric motor 4 is stopped. However, if the blade 2 becomes inoperable due to an external obstacle or the like during operation, the contacts of the switches 5 and 6 will not open, and the electric motor [4 will remain energized, and the blade 2 and the motor 4 will be restrained. continue. As a result, the shaft 3 of the blade 2 is destroyed and the t! of the motor 4 is damaged. Problems such as 4111 burning occurred.
本発明は上記のような問題点を解決するために成された
ものであり、羽根が拘束された場合でも羽根の軸や電動
機の損傷を防止することができる空気調和機を提供する
ことを目的とする。The present invention was made in order to solve the above-mentioned problems, and an object of the present invention is to provide an air conditioner that can prevent damage to the blade shaft and electric motor even when the blades are restrained. shall be.
本発明に係る空気調和機は、吹出口の気流の吹出方向を
変更させる羽根を駆動する電動機のｉｉｔ流値あるいは
通電時間を検出する検出手段を設け、この検出手段の出
力に応して電動機への通電を遮断するものである。The air conditioner according to the present invention is provided with a detection means for detecting the IIT flow value or energization time of the electric motor that drives the blades that change the blowing direction of the airflow from the outlet, and the electric motor is controlled in accordance with the output of the detection means. This is to cut off the power supply.

電時間も長くな６る。従って、検出手段は電動機の電流
値あるいは通電時間を検出することにより電動機の拘束
を検出することができ、これに応じて電動機への通電を
遮断する。When a motor is restrained while being energized, its current value increases and the energization time becomes longer6. Therefore, the detection means can detect the restriction of the motor by detecting the current value or the energization time of the motor, and accordingly cuts off the energization to the motor.
以下、本発明の実施例を図面とともに説明する。 Embodiments of the present invention will be described below with reference to the drawings.

。In FIG. 1, 10 is a ta detector that detects the 'iit current flowing through the electric motor 4, 11 is a controller such as a microcomputer, and 12 is an it i which is controlled by the controller 11.
12a is the contact point of the on/off relay of JI machine 4.

ップ１６に進み、異常信号を出力して終了する。Next, the operation of the above configuration will be explained using the flowchart shown in FIG. Electric 8!4 is energized according to the blowing temperature,
The process of changing the position of the blade 2 is the same as the conventional one. When the blade 2 or motor 4 is locked, switch 5.6
The contacts of J'4. are not opened and the motor 4 is connected to J'4. continues to be. If the current value that flows when the electric motor 4 is normally operating is 10, the current value that flows when the electric motor I14 is restrained is considerably larger than 1G. Therefore, current detector 1
The electric motor 4 is turned on and off according to the current value i detected by 0. In the flowchart of FIG. 2, when the electric motor 4 is operating normally, the current value i is equal to i, so the process proceeds from step 13 to step 14, and the relay contact 1
2a is turned on to continue energizing the electric motor 4. When the electric motor 4 is restrained, the current value i becomes larger than 10, and the process proceeds from step 13 to step 15, where the relay tI point 12a is turned off and the il! The process then proceeds to step 16 where an abnormality signal is output and the process ends.

may be set a little higher, and in the above embodiment, the electric current I! may be set to a slightly higher value. The relay 12 that drives the switch 14 was turned on and off, but since the time required to operate the blade 2 and turn off the switches 5 and 6 is limited, as shown in step 18 of the flowchart shown in FIG. Even if the process proceeds to step 15 and the relay contact 12a is turned off when the energization time T to the motor 4 etc. becomes longer than the normal operation time T0, the same effect as in the above embodiment can be obtained. Note that in step 17, the current detector 10 determines whether or not energization of the electric motor 4 has started.

防止することができる。As described above, in the present invention, when the electric motor is restrained directly or through the blades when the blowing direction is changed, the detection means detects the restraint of the motor and cuts off the power supply to the motor. Damage to the drive mechanism and electric motor can be prevented.
