JP2002106936A - Method for displaying humidity of air conditioner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for displaying humidity of air conditioner by which the problem raised by the conventional method can be eliminated that a large error occurs in the humidity value displayed on a humidity displaying device annexed to the indoor unit main body of an air conditioner due to the operating state, particularly, the operating air volume of the air conditioner. SOLUTION: The indoor air volume of the air conditioner is detected from the number of revolutions of an indoor fan and, when the number is a fixed value or lower, the occurrence of an error is suppressed by adding a correction value to a detected humidity value. When the number of revolutions is the fixed value or lower, in addition, accurate humidity display is made by prolonging the displaying interval of the detected humidity value on the humidity displaying device.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a humidity detected by an air conditioner having a humidity detecting device and a humidity displaying device and displaying indoor humidity.

[0002]

2. Description of the Related Art Conventionally, in this type of technology, it has been difficult to improve the detection accuracy because the detected humidity changes depending on the operation state. In particular, when the operating air volume of the indoor unit was reduced, the detection accuracy was greatly reduced due to the deterioration of the flow of air around the humidity detection device.

[0003]

However, in order for the air conditioner to operate stably or for the user to feel comfortable in an air-conditioning environment that is stably controlled,
Overcoming the above issues is essential. In particular, in recent years, since the control of the air conditioner is required to be fine, it is necessary to operate the air conditioner with a weak wind or a light wind, and the necessity of overcoming the above-mentioned problems is becoming more apparent.

[0004]

In order to solve the above-mentioned problems, according to the present invention, when the operating airflow of an indoor unit falls below a set value, the detected humidity is corrected according to the value.

When the operating airflow falls below a set value, the interval for displaying the detected humidity on the humidity display device is extended in accordance with the value.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention detects the number of rotations of an indoor fan when displaying the humidity in a room detected by a humidity detection device attached to a main body of the room. In this case, erroneous detection of humidity due to stagnation of air around the humidity detection device can be suppressed by adding a predetermined correction value.

[0007] When the indoor fan is below a certain rotation speed,
By making the interval for displaying humidity on the humidity display device longer than usual, errors and hunting in the displayed humidity are suppressed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. (Embodiment 1) In FIG. 1, a humidity detection device 1 and a humidity display device 2 are connected to an indoor unit via an indoor unit control device 3. The humidity display device has five LEDs and the humidity is 4
1 if less than 0%, 2 if more than 40% and less than 50%
3 pieces in case of 50% or more and less than 60%, 70% or more in 60%
The detected humidity is displayed by turning on four lights when it is less than% and five lights when it is more than 70%.

Here, when the indoor air volume decreases, the occurrence of an error can be suppressed by detecting the rotation speed of the indoor fan and correcting the detected humidity by the indoor control device.

Further, by simultaneously increasing the interval of displaying on the humidity detecting device, hunting of the number of lighting of the humidity display LED is prevented, and accurate humidity display becomes possible.

[0011]

As is apparent from the above embodiment, the accuracy of the detected humidity can be improved by performing the humidity correction when the indoor air volume decreases.

Further, according to another aspect of the present invention, it is possible to display humidity with high accuracy by extending the display interval.
