Abstract

PURPOSE:To improve indoor temperature distribution under preventing the feeling of cold air by a method wherein the blow-off speed of the blow-off amount of air is detected and the distributing and deflecting operations of blow-off airflow are determined based on the result of detection. CONSTITUTION:In case the blow-off air speed, detected by an air speed sensor 6, is smaller than a value set in a comparator 11, the blow-off airflow 14 is not branched and passes a central floor surface, however, the feeling of cold air is not felt since the air speed is small. In case a sufficient room heating capacity is desired and a large amount of blow-off air is necessitated, the air speed sensor 6 rotates motors 9, 10 through a motor control circuit 12 when the sensor 6 has detected an air speed higher than a given value set in a comparator 11, vanes 4 are turned to branch and deflect the blow-off airflow 15. In this case, the blow-off airflow does not effect directly on inhabitants 16 in a room and the feeling of cold air will never be felt by them. Further, the direction of the blow-off air is maintained in proper downward direction without spoiling good temperature distribution in the room, therefore, the temperature distribution in the whole of the room may be kept in excellent.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an air conditioner.

Conventional Technology As a means of maintaining a good temperature distribution during heating, conventional methods have been used to direct the blowing airflow appropriately downward. However, at this time, as shown in Figure 6, the blown airflow passes through the central floor of the living area and acts directly on the human body, so if the blown airflow is low temperature or the airflow velocity is high, a feeling of cold air will occur. There is a problem.

To deal with this problem, conventional techniques such as equity 1]g5
5-1 OSI Publication No. 3 shows an example in which the blowing air is directed outside the living area to prevent the feeling of cold wind when the blowing air is warm or low temperature.

Further, Japanese Utility Model Publication No. 55-39232 discloses a means for preventing the feeling of cold air by expanding the outlet using the wind pressure of the blown airflow and diffusing the airflow when the wind pressure is large.

Problems to be Solved by the Invention However, the above-mentioned means have the following problems.

First, the former method has the disadvantage that the indoor temperature distribution deteriorates while the direction of the airflow is directed outside the living area. Moreover, the latter means shortens the reach of the blown air stream by diffusing the air stream, thereby worsening the temperature distribution. Furthermore, even if the airflow is diffused and the wind speed is felt, the blown airflow still acts directly on the human body, and the problem of feeling of cold wind cannot be solved.

Therefore, an object of the present invention is to provide an air conditioner that prevents the feeling of cold air and provides a good indoor temperature distribution.

Means for Solving the Problems In order to achieve this object, the present invention provides a blowout airflow dividing/deflecting means for dividing and deflecting the blowout airflow into a plurality of parts, and a blowout airflow volume or blowout wind speed detection device for detecting the blowout air volume or blowout wind speed. and a blowout airflow diversion deflection means control device that controls the blowout airflow diversion deflection means based on the output of the blowout airflow volume or blowout wind speed detection means.

Function The above configuration has the effect of dividing or deflecting the blown air stream by the blown air flow dividing/deflecting means according to the air volume or wind speed detected by the blown air volume or the blown air speed detection means.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 5.

In FIG. 1, reference numeral 1 denotes an air conditioner main body of the present invention, which has a heat exchanger 2, an air blower @3, etc. inside. A vane 4 is rotatably provided at the outlet 5 as a blowoff air flow dividing deflection means. Further, a wind speed sensor 6 is provided at the air outlet 5 as a means for detecting the air speed.

Figure 2 is Vane 4's episode! 0 mechanism is shown. Vane 4
A plurality of air outlets are provided at the outlet S, and the left and right sets are divided at the center of the outlet 5, so that the direction of the airflow can be changed independently for each set. Drive is provided by motor 9.1o via linkage 7.8.

Figure 3 shows a block diagram of the system (goods). A comparator 11 that compares the output of the wind speed sensor 6 with a certain constant value, a motor control circuit 12 that controls the motor 9.10 based on the comparison result by the comparator 11, and a motor 9.10 that rotates the vane 4. 1o.

In addition, the comparator 11, the motor control circuit 12, and the motor 9.1
0 constitutes the blowout air flow dividing deflection means control device 13.

The operation when heating operation is performed in the above configuration will be explained.

When the blowout wind speed detected by the wind speed sensor 6 is smaller than the value set in the comparator 11, the blowout airflow 14 is blown out without being divided, as shown in FIG. At this time, the blowout airflow 1
4 passes along the center floor of the room, but the wind speed is low so it does not give a feeling of cold air.

On the other hand, when it is desired to obtain sufficient heating capacity, such as during startup, a large volume of air is required, and therefore the air velocity is also high and if the method described above is used, the air feels cold and is very uncomfortable. Therefore, when the wind speed sensor 6 detects a wind speed equal to or higher than a certain value set in the comparator 11, the motor 9, 10 is rotated via the motor control circuit 12, and as a result, the vane 4 is fully rotated, as shown in FIG. The blown airflow 15 is divided and deflected as shown.

At this time, the blown air current does not directly act on the occupant 16 in the room, and therefore no cold air feeling occurs. Furthermore, since the direction of the airflow is maintained in a moderate downward direction without impairing the temperature distribution in the room, comfortable air conditioning is possible with good temperature distribution throughout the room and no feeling of cold air. .

Next, as another embodiment, a case will be briefly described in which a signal of a tap position for switching the rotational speed of a blower is detected as the blowout air volume or blowout air speed detection means.

In the first embodiment, the wind speed sensor 6 is used as the blowout wind speed detection means, but the same effect can also be obtained by detecting a signal from a contact position (not shown) for switching the air volume. Furthermore, in this case, since the wind speed sensor 6 is not required, there is also the effect that the cost can be reduced.

Effects of the Invention As described above, the air conditioner of the present invention provides the following effects.

(1) Since the configuration detects the blowout air speed or blowout air volume and determines the branching/deflection operation of the blowout airflow based on the result, the blowout method that always maintains a good indoor temperature distribution according to the blowout air speed or blowout air volume is possible. It is possible.

■ Even when the blowing air velocity or the blowing air volume is high, it is possible to control the blowing air so that it does not directly shine on the human body, so a very comfortable air conditioning effect without the feeling of cold air can be obtained.
