DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for automatically controlling the indoor environment so that residents are comfortable.

[0002]

2. Description of the Related Art A conventional air conditioner is controlled so as to maintain a room temperature within a certain temperature range. However, the air conditioner should be designed to keep the sensation of heat of a person resident therein comfortable. In order to realize such comfort, a comfort index called PMV is proposed, and based on this index, an air conditioner is controlled as disclosed in Japanese Patent Application Laid-Open Nos. 2-178555 and 2-2.
No. 42037 is disclosed. PMV (Pred
(Icted MeanVote) is translated as an average expected thermal sensation report and is one index for evaluating the comfort of a thermal environment. It was proposed by Professor Wanger of the Technical University of Denmark, and was internationally standardized as ISO-7730 in 1984. It is a thing.

[0003] This PMV is a function of temperature, humidity, radiation temperature and air flow velocity which are environmental elements and the amount of activity and clothes which are human body elements.
730. It is assumed that the PMV value 0 is neutral and comfortable, 3 is hot, 2 is warm, 1 is slightly warm, -3 is cold, -2.
Is defined as cool and -1 is defined as slightly cool. Also,-
In the range of 0.5 <PMV value <0.5, 90% of the persons are comfortable, and this range is defined as the comfortable range. The description of the formula and the calculation method is omitted.

Japanese Patent Laid-Open Publication No. Hei 2-178555 discloses an air conditioner that calculates an optimal PMV value by expressing the amount of activity and the amount of clothing, which are factors on the human body side of a PMV, in a fuzzy set, and makes the PMV value neutral. To control. Also, Japanese Patent Laid-Open No.
Japanese Patent No. 242037 discloses a method of installing a detecting means for detecting temperature, humidity and radiation temperature in a living area, calculating a PMV value from a setting means for setting an air flow velocity, an activity amount, and a clothing amount, and
In addition to cooperatively controlling various air conditioners so that the value becomes neutral, the control target value set in the comfortable range by the input of warmth of "hot" or "cold" is corrected.

[0005]

However, in the conventional method, since there is no indication that the air conditioner is operating in response to the operation of inputting the feeling of warmth, the user is anxious. Therefore, there is a possibility that the user may perform the warmth input operation a plurality of times at a time, and the correct PMV value cannot always be corrected.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and eliminates the inconvenience of a user by eliminating inconvenience caused by frequent operations of inputting a warm feeling, thereby achieving an accurate PMV value correction desired by the user. It aims at providing a harmony machine.

[0007]

In order to achieve this object, an air conditioner according to the present invention comprises: a cooling / heating means for cooling or heating a room; a PMV value calculating means for sequentially calculating a PMV value in a living area; A warm feeling input means for inputting a user's feeling such as hot or cold; a correction amount specifying means for determining a correction amount based on the input of the warm feeling input means; and a PMV value obtained by the PMV value calculating means. A PMV value correcting means for correcting by a correction amount determined by the correction amount designating means;
When the MV value is not within the range of the comfortable region, a thermal sensation input reception prohibiting unit that does not accept the input of the thermal sensation input; and a reception display unit that notifies a user that the operation by the thermal sensation input unit has been received. , A comfort display means for displaying whether the PMV value is within the comfort area or not, and a cooling / heating control means for controlling the cooling / heating means so that the PMV value is stabilized within the comfort area. .

[0008]

The present invention displays whether or not the air conditioner is responding due to the operation of inputting warm feeling with the above-described configuration. Therefore, the present invention can be used even when the PMV value is not within the comfortable range. The user can input the current sense of warmth to check the operation, and the user can grasp the current operation of the air conditioner and correct the PMV value accurately.

The indoor blower 33 can set the air volume in three stages of “strong”, “medium”, and “weak”. An indoor unit 35 is installed indoors, and an outdoor unit 36 is installed outdoors. Switching between the cooling operation and the heating operation is performed by switching the four-way valve 29 to switch the flow of the refrigerant in the refrigeration cycle.

An operation example of the air conditioner having the above configuration will be briefly described with reference to the drawings. In the example of FIG. 1, the air volume is set to “strong”, the activity amount is set to “light”, and the clothing amount is set to “winter clothes”.
When the PMV value obtained by the MV value calculating means 1 is -1.5
In this state, the PMV value is out of the comfortable range on the negative side, so the cooling / heating means 9 performs the heating operation,
The PMV value gradually increases and approaches the comfortable area. At this time, the comfort sign 11 is turned off. When the PMV value enters the comfortable region, the comfort sign 11 is turned on, and the cooling / heating means 9 repeats the operation / stop, and the PMV value is neutral and stable.

After that, when a warm feeling input operation is performed by the warm feeling input means 8 and the PMV value is separated from the neutral state, the comfort sign is turned off again and the reception completion sign 15 is turned on. At the time when this thermal sensation input operation is performed, the segments of the thermal sensation monitor 20 are lit left and right by the number of operations, and 10 seconds after the final operation, the thermal sensation input is determined and the segments of the thermal sensation monitor are displayed only in the center, After confirmation, the reception completion sign lights up until the vehicle enters the comfortable area. During this time, the user can correct the PMV value using the warm feeling input means 8 and the warm feeling monitor 20.
