Abstract

PURPOSE:To provide comfortable air conditioning by a method wherein means for discriminating a blowing angle is arranged to set the specification of an angle for means for deflecting the blowing angle through a position setting switch to be operated in accordance with fixing height of an indoor unit. CONSTITUTION:A changing-over switch 2 can perform three types of setting, (a), (b) and (c). Installing position corresponds to a ceiling by (a), an upper part of closet by (b) and a lower part of closet by (c). During a heating operation, in case of ceiling installing at (a), the blowing direction under a normal operation is in a direction B, the upper part of the closet at (b) is in a direction of D and the lower part of the closet at (c) is in a direction F. The most suitable angle at the specified location is set by a micro-computer 3 and its selection is carried out by the setting switch 2. A motor 5 may directly drive a blowing angle deflection plate and a control over the energization time for the motor 5 is carried out by the microcomputer 3. In case of energization, the control is carried out by turning ON a relay 8 and a rotational direction of the motor 5 can be changed over by a relay 9. An energization time corresponding to a position changing-over switch 2 and a rotational angle are set in advance in the blowing angle discriminating means and a blowing control can be carried out which can correspond to any location by changing-over the change-over switch 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner that can be installed in two or more locations, such as the ceiling of a room or the upper and lower parts of a closet, such as a residential integrated air conditioner. This invention relates to a blower control device.

4 and 5 are perspective views showing how the indoor unit of a residential air conditioner is installed on the ceiling and the lower part of the closet, respectively. In the case of ceiling installation, as shown in FIG. It is constructed by combining an indoor unit main body 101 with an air outlet duct 102 and a grill 103, and when installed at the bottom of a closet, the indoor unit main body 101 is
A blowout tallit 104 for pushing in and a suction/blowout grill 105
It is composed of a combination of.

The Suita style air blowing angle of an air conditioner is generally a fixed setting type, and is set by the user depending on the installation location of the indoor unit.

Problems to be Solved by the Invention However, in conventional residential air conditioners, the blowout angle selected by the user remains the same unless the user changes it, even if the blowout temperature changes and feels worse. I couldn't say it.

Additionally, since room temperature generally has the property of warm air rising and cold air falling, when considering air conditioning of the entire room, the blowing direction must also be varied between heating and cooling. be.

It is also possible to perform this control automatically, but in this case, the installation location is usually fixed at - location, so
In configurations such as residential air conditioners that are installed in various locations such as the ceiling of a room or the bottom of a closet, there is a problem that cannot be solved by controlling the air blowing direction based on an automatically set uniform range.

In view of the above-mentioned conventional problems, the present invention provides comfortable air conditioning by varying the blowing angle according to the installation height of the indoor unit.

Means for Solving the Problems In order to solve the second problem, the present invention, as shown in FIG. Comparing means for comparing the temperature detected by the means and the temperature set by the temperature setting means;
In the operation control device equipped with a blow-off angle deflecting means for vertically deflecting air blowing out from the blow-off port of the air conditioner according to a signal from the comparison means, the installation of the indoor unit of the air conditioner corresponds to the height. By operating the position setting switch and this position setting switch,
A blowout angle determining means is provided for setting an angle instruction to the blowout angle deflecting means.

Effect With this configuration, by operating the position setting switch according to the installation height of the indoor unit, the angle of the air blown from the indoor unit can be optimally controlled at the installed location.

Embodiment Hereinafter, the present invention will be described with reference to FIG. 2 of the accompanying drawings showing one embodiment thereof.
This will be explained with reference to FIG.

In FIG. 2, 1 is a suction temperature thermistor that detects the suction temperature of air. Reference numeral 2 denotes a changeover switch that can be switched depending on the installation position of the indoor unit (ceiling, upper part of the closet, lower part), and corresponds to the position setting switch in FIG. 3 is a microcomputer that compares the electric signal from the suction temperature thermistor 1 with the electric signal from the temperature setting volume 4, and based on the results, determines the operating condition and the direction of the blowing air. It has a function of outputting a control signal to the motor 5 that drives the blowout and angle deflection plate 6. That is, this microcomputer functions as the comparing means and blowing angle determining means shown in FIG.

The operation of the above configuration will be explained with reference to FIG. 3.

The changeover switch 2 can be set to three settings: a, b, and c, and the corresponding installation location is a on the ceiling, on the upper part of the closet, and C on the lower part of the closet.

Here, the case of heating operation will be explained. In the case of ceiling installation (a), the blowing direction during normal operation is set to the sun direction, the D direction at the top of the closet (b), and the F direction at the bottom of the closet (C). 3, and the selection is made using the setting switch 2. The motor 5 directly drives the blow-off angle deflecting plate, and the microcomputer 3 controls the energization time to the motor 5. When energizing, relay 8 is turned on, and the rotation direction of motor 5 can be switched by relay 9. Therefore, by setting the energization time and rotation direction corresponding to the position changeover switch 2 in advance in the blowout angle determining means, by switching the changeover switch 2, air blowing control can be performed that can be adapted to any installation location.

As another example, it is common to control the airflow direction to vary depending on the airflow temperature in the room. If the blowout temperature is lowered, the air will not directly hit the human body, and the installation angle and range of the air conditioner indoor unit 7 will vary depending on the location.

Therefore, by the microcomputer 3, the relay 8
The ON time of the relay 9 and the 0N10FF of the relay 9 make it possible to control the rotation angle and rotation direction, which can be handled by the same control device.

In addition, in the previous embodiment, the installation of the indoor unit 77'-- was explained in which the air blowing angle from the outlet can be changed depending on the height, but the air blowing direction (range) can be changed automatically at a fixed period. If a so-called swing function is provided, the air blowing range may be changed in conjunction with the changeover switch 2.

In other words, the basic configuration includes a separate automatic swing switch 2.
0 is provided, and the air blowing range can be selected by the input signal of this switch 20 and the amble position signal of the changeover switch 2, for example, 300 in case of a, 75° in case of b, and 60' in case of C. By adding a selection mode, this can be achieved in correspondence with design matters.

Effects of the Invention As described in 2., the present invention allows the installation of an air conditioner to easily change the blowing direction according to the height, and each installation can be performed using a control device according to the height. There is no need to prepare a controller, and the same control device has versatility.

Therefore, economic, cost-effective and maintenance
It is also very effective when responding to services. Furthermore, since the blowing direction can be controlled automatically compared to conventional manual fixing, comfort can be easily improved. Particularly in the case of residential air conditioners, it has been difficult to provide versatility in the control content because the blowing directions are different, but the present invention can easily provide versatility in automatic control.
