[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to a temperature control system.

[0002]

2. Description of the Related Art Conventionally, as a temperature adjusting method for an air conditioner, as shown in FIG. 7, a remote controller transmitting unit and its panel are set to set a target temperature to "standard" or "high" or "low". A temperature setting key is provided, the main body of the air conditioner is equipped with a remote control receiving unit for receiving the temperature set value from the remote control transmitting unit and a temperature set value storage unit for storing the temperature setting value, and the temperature for measuring the room temperature is set. The target temperature and the room temperature are provided with a detection unit, a compressor and a compressor drive unit, a fan and a fan drive unit, a control unit for controlling them, and a control unit memory that stores control data necessary at that time. And the amount of change, and the control unit controls the compressor through the compressor drive unit and the blower fan through the fan drive unit to perform cooling or heating operation to determine the temperature difference between the target temperature set value and room temperature. I'll lose Scheme that was basic. In this case, the key operation of the remote control to set the target temperature is
Some elderly people and women are not good at using the functions, and most of the functions are not used, and the increase in the number of remote control devices increases the complexity of searching for remote controls, which is not easy. Further, the target temperature is, for example, a standard temperature of 24 ° C., and the adjustment amount per key operation of the remote controller is + 2 ° C. for “high” and −2 ° C. for “low” as a constant temperature difference of Celsius. Since the setting is made, a single key operation on the remote controller causes a difference from the sensible temperature felt by the user's body,
It was necessary to repeat the operation, and the room temperature at which the user felt comfortable was different due to changes in the user's physical condition and climate, and sufficient comfort was not obtained.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art. The target temperature setting can be easily performed without operating the remote controller, and the user can operate at the present room temperature. Another object of the present invention is to provide an air conditioner having a temperature adjustment system that quickly adjusts the difference between the sensible temperature felt by the user and the set temperature and improves comfort.

[0004]

In order to achieve the above object, a temperature detecting unit for measuring room temperature, a compressor, a compressor driving unit, a fan, a fan driving unit and a control unit for controlling them. And a control unit memory that stores necessary control data at that time, and controls the indoor fan, the outdoor fan, and the compressor that constitutes the refrigeration cycle based on the indoor temperature and the set temperature, and cool air or warm air is supplied indoors. In an indoor unit of an air conditioner that blows out air to control the temperature in the room, words that express the sensible temperature by the words emitted by the user, such as "hot", "hot and hot", "comfort", "cold", "cold cold" Is provided with a voice input unit for recognizing "" and a voice identification unit for recognizing the voice, preset control rules, membership functions, and fuzzy sets for expressing each word as a sensible temperature. A data memory and a fuzzy engine section for inferring the adjustment amount of the temperature set value corresponding to each word are provided, and the temperature set value is adjusted by the output of the fuzzy inference, and the temperature is set by the words issued by the user. Configured so that the value can be adjusted.

[0005]

According to the above construction, the voice input unit captures a word uttered by the user, converts it into an electric signal, and transmits the data to the voice discriminating unit, and the voice discriminating unit outputs the pre-stored word from this data. It identifies which word in the word and transmits the signal of this word to the fuzzy engine section. Next, the fuzzy engine unit uses the room temperature obtained from the temperature detection unit and the word signal obtained from the voice identification unit to represent the word stored in the fuzzy set data memory as fuzzy temperature. The set rule and the control rule for inferring the adjustment amount of the temperature set value and the membership function are called, and the adjustment amount of the temperature set value is output by fuzzy inference. As a result, since the voice recognition unit can recognize the word indicating the user's sensible temperature, it is possible to know what kind of state the room temperature is for the user at the present time, and the temperature set value corresponds to that word and is "lower". The adjustment amount can be roughly determined as ", considerably lower", "appropriate temperature", "higher", and "reasonably higher". In addition, the amount of adjustment can be obtained by setting the value of the fuzzy set corresponding to each word by the fuzzy engine unit, and it becomes possible to obtain a new set temperature, and this adjustment is repeated for the number of words the user speaks. It becomes possible, and the difference between the set temperature and the sensible temperature can be driven to zero by repeated adjustment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of an air conditioner according to the temperature adjustment method of the present invention. Words that the user feels represent the sensible temperature, such as “hot”, “hot and hot”, “comfortable”, “ A voice input unit 1 for capturing "cold" and "cold" and a voice identification unit 2 for recognizing the voice are provided, and preset control rules, membership functions, and each word are expressed as sensible temperature. Fuzzy set data memory 3 for, and a fuzzy engine unit 4 for inferring the adjustment amount of the temperature set value corresponding to each word
And the temperature detector 5 for measuring the room temperature, and the compressor 1
0, the compressor drive unit 8, the fan 11, and the fan drive unit 9
And a control unit memory 7 for storing the control data necessary for the control and a control unit 6 for controlling them, and the adjustment amount of the temperature set value is determined by the output of the fuzzy inference by the fuzzy engine unit 4. In this way, the temperature setting value can be adjusted by the words emitted by the user.

Next, the operation of this system will be described. When the user of the air conditioner utters a word indicating the sensible temperature with respect to the room temperature at the present time, the voice input unit 1 captures this. The word captured by the voice input unit 1 is recognized by the voice identification unit 2 and stored as a signal corresponding to the word. On the other hand, the temperature detector 5 measures the room temperature and temporarily stores it.

Next, an operation algorithm for determining the adjustment amount of the set temperature by fuzzy inference in the fuzzy engine section 4 will be described. The primary stored word signal is transmitted to the fuzzy engine unit 4, and the fuzzy engine unit 4 reads out the data expressed by the fuzzy set from the fuzzy set data memory 3 for each word signal as shown in FIG. The fuzzy set that represents a signal of a word indicates the sensible temperature of the user and roughly expresses the distribution of the temperature difference with respect to room temperature. On the other hand, the room temperature measured by the temperature detecting unit 5 is also transmitted to the fuzzy engine unit 4, and the temperature difference Δ between the room temperature and the sensible temperature Δ.
T is calculated. For example, the temperature difference ΔT when it is “hot”
Is shown in FIG. Next, the membership functions NB (NEGATIVE BIG) and Z0 (ZER) shown in FIG. 4 are shown as the antecedent part of the fuzzy inference using the temperature difference ΔT as an input.
O) and PB (POSITIVE BIG) are read from the fuzzy set data memory 3, and the minimum value is obtained from the intersection of each membership function and the temperature difference ΔT. It should be noted that although there are three types of membership functions, more types may be provided. Next, the rule shown in FIG. 6 will be described. The rule (A) means “if the temperature difference ΔT has a large negative value, set the adjustment amount ΔTADJ of the temperature set value to a large negative value”. Similarly, the rule (B) means “if the temperature difference ΔT is substantially zero, set the adjustment amount ΔTADJ of the temperature set value to zero”. The rule (C) means “if the temperature difference ΔT has a large positive value, set the adjustment amount ΔTADJ of the temperature set value to a large positive value”. Using the rule shown in FIG. 6, the membership function NB, Z0, P of the consequent part of the fuzzy inference shown in FIG.
The maximum value with B is calculated, the center of gravity is calculated, and defuzzification is performed to calculate the adjustment amount ΔTADJ of the temperature set value. The calculated adjustment amount ΔTADJ is added to the old set temperature and stored in the fuzzy engine unit 4 as the new set temperature.

Next, as shown in FIG. 1, the new set temperature of the fuzzy engine section 4 and the room temperature data of the temperature detecting section 5 are input to the control section 6, and the compressor drive section 8 controls the compressor 10. Further, the blower fan 11 is controlled through the fan drive unit 9 to blow cold air or warm air into the room to control the temperature inside the room. As a result, the room temperature is subjected to additional value control so as to reach the new set temperature, and is adjusted to the sensible temperature corresponding to the "hot" sound.

[0010]

As described above, according to the constitution of the present invention,
In the temperature adjustment method of the air conditioner, the target temperature setting value can be easily adjusted by words such as "hot", "hot hot", "comfort", "cold", "cold cold", Even old people and women who are not good at key operations with the remote control can easily adjust the set values. In addition, the adjustment amount is determined by fuzzy inference, and the adjustment amount corresponds to the word, so the adjustment amount to be performed at once can be selected and adjusted quickly, so the difference between the user's sensible temperature and the target set temperature is eliminated early. It improves comfort.
