Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation control method for an air conditioner equipped with a wind direction changing device that changes the ventilation direction vertically or continuously or intermittently. One of the purposes is to prevent the discomfort that occurs when

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 1 denotes an indoor unit that is installed at a relatively high location indoors, and is equipped with an inlet 2 and an outlet 3, and the outlet 3 has a vertical wind direction that varies from horizontal to downward. A wind direction changing blade 4 is provided.

Reference numeral 5 indicates the wind direction changing blade 4 according to a pulse signal for forward rotation or reverse rotation.
A pulse motor that reciprocates continuously or intermittently in a range from a horizontal direction to a downward direction, and a function of returning the wind direction changing blade 4 so that its air blowing direction becomes horizontal in response to a stop signal of the compressor. It is also equipped with

6 is a cross flow fan, which is driven by a motor 7.

This motor 7 has a high-speed switching control function as is well known, and performs the switching operation in conjunction with the return operation of the pulse motor 5 using a well-known configuration including a micro switch and the like. 8 is air guider, 9 is stabilizer, 10
1 is an indoor heat exchanger, 11 is a water tray, and 12 is a temperature sensor that detects the temperature of the intake air.

13 is an outdoor unit that is paired with the indoor unit;
It is equipped with a compressor 14, an outdoor heat exchanger 15, etc. that constitute a well-known refrigeration cycle together with the indoor heat exchanger 10,
These are connected by piping 19.

16 is an outdoor fan motor, and 17 is a fan.

In the above configuration, when the compressor 14 is driven and the refrigeration cycle is operated, the motor 7 simultaneously rotates to cool the room. When a signal for moving the wind direction changing blade 4 is issued, the pulse motor 5 is activated, thereby causing the wind direction changing blade 4 to reciprocate within a predetermined angle range, thereby improving the temperature distribution in the room. When the temperature sensor 2 detects the set temperature, the operation of the compressor 14 is stopped, and at the same time, the pulse motor 5 also performs a return operation, and the wind direction changing blade 4 is returned so that the air blowing direction is horizontal.

In conjunction with this, the fan motor 7 is also switched to low speed rotation, reducing the air blowing capacity. Therefore, the indoor heat exchanger 1
The re-evaporation of the silk dew water that has adhered to the river is suppressed because the air blowing capacity is reduced.

Moreover, as shown in FIG. 4, since the direction of air blowing is horizontal, the air relatively containing evaporated moisture is not blown to the human body and does not cause discomfort. Furthermore, since the air is blown horizontally, when the air conditioner is not operating, the indoor unit circulates the air from the ceiling, so there is no need to unnecessarily draw cold air from the floor, and the room temperature can be maintained. It is also possible to suppress the increase. In addition, in this embodiment, the air blowing direction is returned to the horizontal direction when the cooling operation is stopped, but the return angle is not limited to horizontal and may be slightly upward. It is sufficient as long as it does not directly hit the human body.

Further, the wind direction changing device is not limited to the pulse motor 5, and may be configured to reciprocate the blowing direction within a predetermined range using a well-known link mechanism or the like, or may be a wind direction changing control using a fluid element. . As is clear from the above embodiments, the air blowing control method for an air conditioner according to the present invention sets the air blowing direction in a substantially horizontal direction when the cooling operation is stopped to prevent condensate adhering to the heat exchanger from blowing directly into the human body. Discomfort due to re-evaporation of fog water and acceleration of temperature rise due to unnecessary indoor air retention can be prevented.

Furthermore, since the rotation speed of the blower is reduced when the cooling operation is stopped, re-evaporation of the dew supply water is suppressed as much as possible, so there are various advantages such as no loss of comfort.
