EMBODIMENT OF THE INVENTION Hereinafter, the air conditioner which concerns on this invention is demonstrated to an example by taking a wall-mounted air conditioner. First, the whole structure of an air conditioner is demonstrated using FIGS. 1 is a configuration diagram of an air conditioner. 2 is a cross-sectional view of the air conditioner indoor unit. 3 is a front view of the indoor unit.

The air conditioner 1 shown in FIG. 1 is comprised by connecting the indoor unit 2 and the outdoor unit 3 with the connection pipe 4. The indoor unit 2 includes an indoor transmission / reception unit 16 that receives an infrared operation signal from a separate remote controller (hereinafter referred to as a “remote controller”) 5.

As shown in FIG. 2, the indoor unit 2 is provided with a heat exchanger 7 at the center of the housing base 6. Downstream of the air flow of the heat exchanger 7 is arranged an indoor blower 8 of a crossflow fan system having a length approximately equal to the width of the heat exchanger 7. In addition, a dew support plate 9 is disposed below the heat exchanger 7. The heat exchanger 7 and the indoor blower 8 and the like are covered with the decorative frame 10, and a front panel 11 is provided on the front surface of the decorative frame 10.

Above the indoor unit 2, an air inlet 12 for sucking indoor air is provided. Below the indoor unit 2, the air blower outlet 13 which blows out the air which adjusted temperature and humidity is provided. The indoor air sucked from the air inlet 12 by the indoor blower 8 passes through the heat exchanger 7 and the indoor blower 8 to a blower air passage 8a having a width approximately equal to the length of the indoor blower 8. Inflow. Thereafter, the air in the blowing air path 8a is deflected left and right by the left and right wind direction plates 14 positioned in the blowing air path 8a, and is vertically up and down by the up and down wind direction plates 15 positioned in the air blowing holes 13. The direction is deflected and blown out from the air jet port 13 into the room.

On the inner side of the upper and lower wind direction plates 15, a pyroelectric infrared sensor 17, a radiation sensor 18 using a thermopile, and a sound sensor 19 using a microphone or the like are mounted.

Next, a method of subdividing and detecting the activity amount of the occupant by combining the pyroelectric infrared sensor and the sound sensor will be described with reference to FIGS. 4 to 15. In this embodiment, the pyroelectric infrared sensor and the sound sensor are combined to further subdivide the activities of the occupants, and to perform further energy saving operation while considering the comfort of the occupants.

By using a pyroelectric infrared sensor, the amount of activity in the occupants is detected, and if the amount of activity is large, the room temperature is lowered. If the amount of activity is small, the room temperature is adjusted high. have. However, the use of only pyroelectric infrared sensors to classify the amount of activity of the occupants in multiple stages requires increasing the number of sensors due to a detection error or a characteristic that the sensitivity of the sensor is deteriorated with respect to the movement in the direction toward the sensor. This adds to the cost.

4 is a relationship between activity content and activity amount. MET is used as a unit representing the amount of activity of a person, and the activity content and the MET value corresponding to the activity content are shown. In the left column of FIG. 4, a division example of the amount of activity when only one pyroelectric infrared sensor is used is shown. Thus, when only one pyroelectric infrared sensor is used, the amount of activity can be divided into three divisions of large, medium and small. Even if it subdivides more than this, precision is low for the reason mentioned above. In the right column of Fig. 4, a division example of the amount of activity by the method of the present invention is shown. According to the present invention, since the amount of activity can be further subdivided, further energy-saving operation can be performed while considering comfort by air conditioning according to the amount of activity of the occupants. In addition, the method of classifying the amount of activity by this invention is mentioned later.

Next, the outline | summary of control of the air conditioner of this invention is demonstrated using FIG. 5 is a control block diagram of the indoor unit.

In FIG. 5, the air conditioner 1 includes a control unit 20 therein, and controls the indoor unit 2 and the outdoor unit 3 in accordance with information from various sensors or instructions from the remote controller 5. do. Information from the room 900 may include room temperature sensor 25, humidity sensor 26, radiation sensor 18, remote controller ambient temperature sensor 27, remote controller position sensor 28, pyroelectric infrared sensor 17. , By a sound sensor 19 or the like, is introduced into a microcomputer (not shown) inside the control unit 20. Based on the information introduced into these microcomputers, the air conditioner 1 is controlled.

From the information of the pyroelectric infrared sensor 17 and the sound sensor 19, the activity amount determining unit 35 divides the activity amount of the occupants into multiple stages as illustrated in the right column of FIG. 4, and the temperature shift value setting unit 36 To pass.

The temperature shift value setting unit 36 calculates the temperature shift value based on the information from the calender function 29 provided in the various sensors and the control unit 20 described above, in addition to the activity amount information from the activity amount determining unit 35. Then, it transfers to the target room temperature setting part 37.

The target room temperature setting unit 37 calculates the target room temperature on the basis of the temperature shift value information from the temperature shift value setting unit 36 and the set room temperature information from the room temperature setting unit 38 to the air conditioning capacity control unit 45. To pass.

The air conditioning capacity control unit 45 uses the compressor rotation speed setting unit 46 and the indoor blower rotation speed setting unit 47 based on the target room temperature from the target room temperature setting unit 37, the intake air temperature information from the room temperature sensor 25, and the like. ), The compressor speed, the indoor blower speed, and the outdoor blower speed are set in the outdoor blower speed setting unit 48 to control the compressor, the indoor blower 8, and the outdoor blower 56.

The heating capacity and cooling capacity of the air conditioner are controlled based on the intake air temperature and the set temperature of the air conditioner. However, in general, the intake air temperature of the air conditioner installed in the high place of the room is higher than the temperature of the living space from the floor of the room where the user is located to the face height. Therefore, in order to correct this temperature difference, the air conditioner is controlled so that the intake air temperature is close to the additional set temperature (target temperature) with the additional set temperature at which the predetermined value (temperature shift value) is added to the set temperature as the target temperature. do. The predetermined value varies depending on the structure of the air conditioner and the operation mode (heating / cooling / dehumidification), but is about -1 to 5 degrees.

The air conditioner maintains comfort by controlling the temperature (and humidity) of the room. A person's sense of warmth is affected by temperature, humidity, airflow, radiation, clothing and activity. When a person's behavior changes, even if conditions such as humidity, airflow, radiation, and clothing amount are the same, the person's sense of warmth changes. Therefore, in order to maintain comfort, it is necessary to change the temperature (and humidity) according to the person's behavior.

Information on the amount of activity of the occupant can be obtained from the human body detecting function provided by the air conditioner. By changing the room temperature according to the information on the amount of activity of the occupants, the comfort of the occupants can be maintained. In the home air conditioner, a pyroelectric infrared sensor is employed as a human body detection function that detects movement of the occupant.

A pyroelectric infrared sensor is a sensor using a pyroelectric effect in which crystals or resins having a large dielectric constant generate electric charges due to temperature changes, and can detect infrared rays emitted from a person without contact. By installing a Fresnel lens in front of the pyroelectric infrared sensor and intermittently inputting infrared rays into the sensor, human motion can be detected. Therefore, when the human body is detected only by the pyroelectric infrared sensor, when movement occurs in the occupant, the output of the sensor is changed to detect that the occupant is moved. On the other hand, when the occupants do not move, the output of the sensor does not change, so that the occupants do not move.

However, the presence or absence of the movement of the occupants alone cannot determine the amount of activity of the occupants. Therefore, in order to determine the amount of activity of the occupants, a plurality of pyroelectric infrared sensors are provided, and when the movement of the occupants is large, the plurality of pyroelectric infrared sensors react, and only one sensor responds when the movement of the occupants is small. In addition, there is a method of determining the size of the activity of the occupants.

However, in such a method, a plurality of pyroelectric infrared sensors are required, which adds cost. In addition, even if there are a plurality of sensors, there is a problem that the amount of activity cannot be discriminated when the movement of the occupant is smaller than the movement that can be detected by the sensor or the same operation. That is, when the human body is detected only by the pyroelectric infrared sensor, it can be seen that there is a limit in the determination of the amount of activity.

In the air conditioner of the present embodiment, the movement of the occupant is detected using a pyroelectric infrared sensor that has been recently adopted, and the sound generated in the room or the like is detected by the sound sensor. When the occupant moves, the sound usually accompanies the movement. By predicting the various scenes in the room where the air conditioner is installed, it is possible to more accurately grasp the amount of activity of the occupants from the detection result of the infrared sensor and the detection result of the sound sensor.

There are a variety of sounds that occur in the room where the air conditioner is being driven. Specifically, the sound of the air conditioner itself, the sound that the occupants are talking to, the sound that the occupant is accompanied by desk work, sewing, light tidying, etc., the sound generated by the operation of a device such as a vacuum cleaner, a cooker, an image container, a television, , Sounds such as radio and audio equipment, music, sound effects, and the like, and sounds generated even in unattended cases such as clocks and sounds of fish tanks.

These sounds can be divided into those accompanying the activity of the occupant and those not related to the activity of the occupant. Sounds not related to the activities of the occupants include the sound of the air conditioner itself, the sound of television, radio, and audio equipment, the sound of music, the effects of sound, the clock, and the pump of a fish tank. Sounds associated with the activities of the occupants include conversations, deskwork, sewing, tidying up, vacuum cleaners, cookers and image containers.

Among the sounds irrelevant to the activities of the occupants, the sound generated even in the absence of people, such as the clock and the sound of the pump of the aquarium fish, should be called the environmental sound of the room where the air conditioner is installed. The sound which added the operation sound of the air conditioner itself to the environmental sound of such a room needs to be distinguished from other sounds.

Among the sounds not related to the activities of the occupants, the sound of the television, radio, and audio equipment, the sound of the music, the effects, and the sound of the air conditioner itself are different from those of the occupants. .

In addition, in the case of using a heavy-use device group such as when using a sound cleaner, which is accompanied by the activity of the occupants, the occupants are actively moving. Thus, from the need for proper air conditioning, such sounds need to be distinguished from other sounds.

On the other hand, the sound of the dialogue among the sound accompanying the activity of the occupants needs to use the sound sensor to finely distinguish the amount of activity of the occupants. In other words, if the voice of the conversation is small, it can be judged to be quietly rested. If the voice of the conversation is big and continues without interruption, the activity of the occupants can be increased, so it can be distinguished from other sounds. There is a need.

When using light-weight equipment groups such as cooking equipment, cooking equipment, desk-work equipment, etc. accompanying the activities of the in-home occupants, the occupants use the light-weight equipment group while moving lightly. Therefore, it is necessary to distinguish it from the case of using a group of heavy-use devices, or when making a break while talking in a quiet voice.

From the above, the type of sound source to be discriminated is the dialogue between the air conditioner itself, the broadcast receiving device group such as a television, the heavy-use device group such as a vacuum cleaner, the light-use device group such as a cooking appliance, and the occupants. Sound sources that cannot be distinguished by them have intermediate movements and sounds, and thus are classified into light-use device groups.

The relationship between the kind of these sound sources and the value of the active quantity MET described in FIG. 4 is as follows. In other words, listening to television and music. 1.0MET, cleaning the room… 3.0 METs, Cooking… 2.0 METs, conversation and phone… 1.0 to 1.8 METs (Not described in Fig. 4 for conversation and telephone, but refer to other data.) Since the air conditioner itself does not change the activity of the occupants, the magnitude of the activity of the occupants by the type of sound source In this order, "high-value device group ≥ light-use device group ≥ conversation ≥ broadcast reception device group ≥ air conditioner itself" is ordered.

Next, a description will be given of a method of determining the amount of activity of the occupant by the sound sensor and the pyroelectric infrared sensor. First, in this embodiment, the behavior of the occupants and the sound of the room at that time are divided into the following two patterns.

1: When the occupant is active and the sound accompanying an activity is generated, the change of fever in a body becomes large. Hereinafter, kind of sound source emitting sound with this activity is called "warm sense fluctuation large sound source".

2: When there is activity of occupant, but there is hardly the sound with activity, change of fever in body is small. Hereinafter, kind of sound source emitting sound not with this activity is called "warm sense fluctuation noise source".

When the sound in the room is caused by a warming-sensing noise source, the detection result of the pyroelectric infrared sensor is divided into a plurality of stages, and the amount of activity of the occupants is determined according to the stages to control the air conditioner. In addition, in the case where the sound in the room is caused by the warmth fluctuation loudness source, if the volume of the sound is large, it is determined that the activity is active, and in the case of the warmth fluctuation noise source, than the amount of activity of the occupants determined from the detection result of the infrared sensor. It determines with a large amount of activity, and controls an air conditioner. In this way, based on the detection result of the sound sensor, by dividing the sound source in the room into a group of the temperature fluctuation noise source and a group of the temperature fluctuation noise source, it is possible to subdivide the amount of activity of the occupants into a larger division. Therefore, with finer control, it is possible to save the air conditioner while considering comfort.

As the warm-sensing fluctuation noise source, as described above, the air conditioner itself or a group of broadcast receiving device groups such as television and radio may be cited. As the warmth fluctuation large-sound source accompanied by the movement of the occupants, the group of the occupants themselves, such as a cleaner, a health promotion device, a juicer, a cooker such as a mixer, a dryer, a shaver, and the like used in addition to the conversation between the occupants themselves Can be mentioned. In this case, the air conditioner itself and the dialogue are a single sound source, but for convenience of explanation, the air conditioner itself and the dialogue are also expressed as groups.

These groups of fluctuation fluctuation large sound sources usually have an electric motor therein to support the user's power, speed and the like. Among these, heavy-use apparatus groups, such as a vacuum cleaner and a health promotion apparatus which require the user's power, are also forced by the user himself, and the duration is comparatively long. A device group that does not force a large amount of activity to a user other than the medium-use device group and a group other than the above-mentioned sound source group shall be referred to as a light-use device group for convenience.

In this way, the air conditioner itself and the broadcast receiving device group are used as the group of the temperature-sensitive fluctuation noise sources, and the dialogue, the medium-use device group, and the light-use device group are the group of the temperature-sensitive fluctuation noise sources. The group of sound sources in the room can be determined, and the sound source can be divided into a group of a warm-sensing fluctuation noise source and a group of a warm-sensing fluctuation loud source according to the determined sound source group. Thereby, the amount of activity of the occupants can be subdivided into more divisions, and the air conditioner can be saved while taking comfort in consideration of finer control.

From this, the sound is divided into a plurality of frequencies according to the frequencies, and the sound size, continuity, irregularity, regularity, and interval of intermittence in each frequency band are evaluated by appropriate indicators, so that the type of sound source is relatively inexpensive and simple. It can be seen that can be estimated.

As an example of the sound accompanying the occupant's activity, the results of frequency analysis of the sound of the cleaner and the human voice are shown in FIGS. 6B and 7A. It can be seen that the sound of the cleaner includes everything from low frequency sound to high frequency sound. In addition, it can be seen that a human voice has a low high frequency sound and a low frequency sound around 1 kHz is louder than other parts. In addition, it can be seen that the sound of the cleaner is continuous, and the human conversation is irregular and intermittent.

As an example of the sound irrespective of the occupant's activity, the results of frequency analysis of the sound of the air conditioner itself and the voice of the television are shown in FIGS. 6A and 7B. It can be seen that the sound of the air conditioner itself is generally low in low frequency and high in frequency. In addition, it can be seen that the sound of the television includes a high frequency sound in addition to the low frequency, and the sound of a high frequency of 4 Hz or more is particularly large as compared with the case of a human voice.

Below, the discriminating method of each sound source group which considered the characteristic of each sound source group is described. At first, when sound with attendant activity does not occur, only sound of wall clock occurring in room without person, sound of circulation pump of ornamental fish tank, sound of air conditioner itself are detected, and sound of room The size is minimal. In this case, the low frequency sound and the high frequency sound are also detected continuously and regularly at a low level. Therefore, when the result of detecting the sound of the room with a sound sensor is below a predetermined level and continues regularly, it is determined that the group of sound sources is the air conditioner itself.

When the occupant is cleaning by the vacuum cleaner, the sound in the room does not hear the voice of the conversation or the sound of the television, but only the cleaner sound. In this case, the low frequency sound, the high frequency sound, and the high and continuous levels are also regular and there is little change in the sound level. Therefore, when the sound of the room is detected by the sound sensor, when the result of the continuous continuous at a predetermined level or more and at substantially the same level is determined, the group of sound sources is determined to be a heavy-use device group.

It is common for a person's conversation to be irregular, to have a lot of low frequencies, and also to have long interruptions. Therefore, when the occupants are watching television, radio, or the like, or when the occupants are talking to each other, it is possible to distinguish the sound from the above-described air conditioner itself or the heavy equipment group. On the other hand, it is difficult to determine whether the sound source is from a group of broadcast receiving devices such as a television or a radio, or whether the rooms are talking to each other. However, in the case of a sound source from a television, a radio, etc., unlike real conversation, silence does not continue for a long time. In addition, high frequency sounds that do not appear in real conversations are included in advertisements or sound effects that enter the middle. Therefore, by combining these features, it is possible to discriminate the conversation with the broadcast receiving device group.

As described above, the sound source which is not discriminated by the air conditioner itself, the heavy-use device group, the broadcast receiving device group, or the conversation according to the above determination procedure is discriminated by the light-use device group.

The determination method of the specific sound source in this embodiment is as follows, considering the above consideration.

1. The sound sensor provided in the air conditioner separates and extracts the sound of the room into a sound of a low frequency band and a sound of a high frequency band during operation of the air conditioner.

2. The separated sound is sampled for a predetermined time at a predetermined sampling period for each frequency band. The ratio BP of the number of times of detection of sound in the low frequency band and the ratio HP of the number of times of detection of the sound in the high frequency band are calculated to be a sampling result.

3. The sampling is performed a plurality of times (m times, in the example 10 times) to obtain BP1 to BPm and HP1 to HPm for each sampling result.

4. The negative level is determined by the magnitudes of BP1 to BPm and HP1 to HPm.

5. Negative continuity is determined by whether all sampling results are equal to or greater than a predetermined threshold defined for each group of sound sources. This judgment method may be used instead of the above judgment method of 4.

6. Negative regularity is determined by whether the difference between the upper limit, the lower limit of the sampling result and the average value of the sampling result is within the judgment range determined for each group of sound sources.

7. The negative irregularity is that the number of times that the sampling result is equal to or greater than the predetermined determination threshold prescribed for each group of sound sources is equal to or greater than the predetermined lower limit threshold defined for each group of sound sources and is equal to or less than the upper limit threshold. It is determined whether or not the above-mentioned conference continuation is interrupted midway.

8. Whether or not there is a long interruption of sound indicates that the number of times that the sampling result is greater than or equal to the predetermined thresholds BT and HT prescribed for each group of sound sources is equal to or less than the predetermined upper limit threshold values BJ and HJ prescribed for each group of sound sources; It is judged whether or not the continuation of the meetings of the thresholds BT and HT or more is interrupted midway and whether the difference between the upper limit, the lower limit of the sampling result and the average value of the sampling result exceeds the predetermined judgment width thresholds BX and HX defined for each group of sound sources. .

The above procedures are combined to determine the type of sound source. For example, based on the sampling result obtained in the order of 1 and 2, if the magnitudes of BP1 to BPm and HP1 to HPm are all less than the air conditioner determination thresholds BPa and HPa at 3, the sound source is determined to be the air conditioner itself. If the magnitudes of the values of BP1 to BPm and HP1 to HPm are all higher than or equal to the heavy use device determination thresholds BPh and HPh, the type of sound source is used as a candidate for the heavy use device group. Next, if the type of the sound source becomes a candidate of the heavy-use device group at 4, and the difference between the upper limit, the lower limit of the sampling result and the average value of the sampling result is 6 within the judgment widths BWc and HWc of the heavy-use device group, Is determined to be a heavy-use device group. In addition, in the figure, the vacuum cleaner is taken as an example of the heavy-use apparatus group. If it is determined in 4 and 6 that the air conditioner itself is not a heavy-use device group as well, then in 7 the number of times that the sampling result is the broadcast reception device determination threshold value BPt or HPt or more is the lower limit number of times of the broadcast reception device group threshold value. When the continuation of the meeting which is equal to or greater than BLt, HLt and equal to or greater than the upper limit number of thresholds BHt and HHt, and equal to or larger than the broadcast receiving device determination thresholds BPt and HPt is interrupted in the middle, the type of sound source is determined to be the broadcast receiving device group. In the figure, the television is taken as an example of the broadcast receiving device group. If it is determined that the broadcast reception device is not 7, then the number of times that the sampling result is the conversation determination threshold value BPs or HPs or more in the same procedure of 7 is the lower limit number of times threshold BLs, HLs or more and the upper limit number of times threshold value. In the case where the continuation of meetings equal to or less than BHs and HHs and equal to or larger than the conversation determination threshold values BPs and HPs is interrupted in the middle, the type of sound source is determined to be conversation. In the case where it is determined that there is no conversation above, the type of sound source is determined to be a light use device group. In addition, in the figure, a group of light-use devices is described.

Next, a method of discriminating each sound source described above will be described in detail with reference to Figs. 8 is a sound source determination block diagram. Fig. 9 is an explanatory view of the primary judgment shear. It is explanatory drawing of a primary determination main part.

The determination of the type of sound source is performed in two stages of primary determination and secondary determination. The sound signal in the room is captured by the microphone of the sound sensor 19, converted into an electric signal, amplified, and separated into a plurality of frequency bands (two frequency bands in the embodiment). The amplified signal converted to an electrical signal is a bandpass filter (or low pass filter) for passing low frequency sounds of 5 kHz or less and a high pass filter (or bandpass filter) for passing high frequency sounds of 4 kHz or more. It is separated, and digitized and delivered to the microcomputer embedded in the control unit.

Next, the flow of 1st determination using the above-mentioned sound detection result is demonstrated using FIG. 11 is a flowchart of an essential part of the primary decision. Electric vacuum cleaners were used as the medium-use device group, and television receivers and the light-use device group were the other. The same applies to the following.

The primary determination is started in step S10, and converted into an electrical signal in step S12, and the digitized sound signal is introduced into the microcomputer. In step S13, the microcomputer samples the digital signal at a predetermined sampling period (500 ms in the embodiment) for a predetermined sampling period (2 seconds in the embodiment). The sampling section ends in step S15. Then, in step S16, the ratio of the sound detection data in the sampled data is calculated for each frequency band, and the sampling result of the sound detection ratio BPn of the low frequency band and the sound detection ratio HPn of the high frequency band is obtained. Until the sampling period ends in step S20, the sampling result is repeated a predetermined number of times (10 times in this embodiment), and the sampling results BP1 to BPm of the low frequency band and the sampling results HP1 to HPm of the high frequency band (m are predetermined Number of sampling sections in a plurality of times) is obtained.

When the predetermined plural sampling sections are finished in step S20, it is determined in step S25 whether the sound source is an air conditioner. Specifically, the sampling results BP1 to BPm and HP1 to HPm and air conditioner determination thresholds BPa and HPa are compared. As a result of the comparison, the sampling results BP1 to BPm in the low frequency band are all less than the air conditioner determination threshold BPa in the low frequency band, and the sampling results HP1 to HPm in the high frequency band are all the air conditioner determination threshold HPa in the high frequency band. In the case of less than 1, the type of the sound source is first determined as the air conditioner itself in step S26. This determination result is accumulated in step S46, and the primary determination ends in step S50.

If it is not determined in step S25 that the sound source is the air conditioner itself, the flow advances to step S30 to determine whether the sound source is a heavy equipment. Specifically, the sampling results BP1 to BPm and HP1 to HPm and the heavy-use device determination thresholds BPh and HPh are compared. As a result of the comparison, the sampling results BP1 to BPm in the low frequency band are all higher than or equal to the medium-use equipment determination threshold value BPh in the low frequency band, and the sampling results HP1 to HPm in the high frequency band are all the high-use equipment determination threshold HPh in the high frequency band. In the case of abnormality, it progresses to step S31 and continues a determination process.

In step S31, the sampling results BP1 to BPm and HP1 to HPm average values BPmean and HPmean are obtained for each frequency band. In addition, sampling results for each frequency band BP1 to BPm, maximum values BPmax, HPmax and minimum values BPmin and HPmin of HP1 to HPm are extracted. If the extracted BPmax and HPmax are equal to or less than the average value BPm and HPm plus the medium value device determination width BWh and HWh, and the extracted BPmin and HPmin are equal to or greater than the average value BPm and HPm minus the value for the medium value device determination width BWh and HWh. In S32, the sound source is first determined as a group of heavy-use devices. This determination result is accumulated in step S46, and the primary determination ends in step S50.

If it is determined in step S30 or step S31 that it is not a heavy use device group, it progresses to step S35 and determines whether a sound source is a broadcast receiving device. Specifically, the sampling results BP1 to BPm and HP1 to HPm and the broadcast reception device determination thresholds BPt and HPt are compared. As a result of the comparison, for each frequency band, the sampling results BP1 to BPm and HP1 to HPm are the broadcast reception device determination threshold BPt and the number of times HPt or more, NBPt and NHPt are the lower limit number of the broadcast reception device thresholds BLt and HLt, and the broadcast is also performed. When the upper limit number of times BHt and HHt of the receiving device is equal to or higher, the flow advances to step S36 to continue the determination process. In step S36, it is determined whether or not the continuation of the broadcast reception device determination thresholds BPt and HPt or more is interrupted in the middle for each frequency band. do. This determination result is accumulated in step S46, and the primary determination ends in step S50.

If it is not determined in step S35 or step S36 that the broadcast reception device group, the flow advances to step S40 to determine a conversation. Specifically, the sampling results BP1 to BPm and HP1 to HPm are compared with the conversation determination threshold values BPs and HPs. As a result of the comparison, for each frequency band, the sampling results BP1 to BPm and HP1 to HPm are greater than or equal to the conversation determination threshold value BPs and HPs, and the number of times NBPs and NHPs are greater than or equal to the lower limit number of thresholds BLs and HLs and the upper limit of the conversation. If the number of times is greater than the threshold value BHs or HHs, the process proceeds to step S41 to continue the determination process. In step S41, it is determined for each frequency band whether or not the continuation of meetings with the conversation determination threshold values BPs and HPs or more is interrupted in the middle. This determination result is accumulated in step S46, and the primary determination ends in step S50.

If it is not determined in step S40 or step S41 that the conversation is performed, the flow proceeds to step S45, where the sound source is first determined as a group of light use devices. This determination result is accumulated in step S46, and the primary determination ends in step S50. In addition, if the voice of the conversation is loud and the sound of the conversation continues without interruption, it is not determined that the conversation is made in step S40 or step S41. In this case, however, the amount of activity of the person having the conversation increases, resulting in a cooking appliance, Since the amount of activity is the same as that of using a light use device group, such as an apparatus for a beauty salon and a desk work, a sound source can be used by a light use device group.

Next, the 2nd determination flow of a sound source is demonstrated using FIG. 12, FIG. 12 is a second decision explanatory diagram. 13 is a flowchart of an essential part of the secondary determination. The primary determination (steps S10 to S50) is repeated a plurality of times (three times in the embodiment), and the sound source is determined by subsequent secondary determination. Fig. 13 shows a procedure of sound source determination including an excerpt of the primary determination processing and the secondary determination processing.

The determination of the sound source is started in step S1. A primary determination is made in steps S10 to S50, and it is determined whether or not the final primary determination is completed in step S55. If the final primary determination has not been completed, the flow returns to step S10 to repeat the primary determination. If the final primary determination has been completed, the flow proceeds to step S56 to start the secondary determination.

First, in the second determination in step S57, a sound source having the maximum appearance frequency is extracted from the results of the plurality of primary determinations. Next, in step S60, it is determined whether there are a plurality of sound sources having the maximum appearance frequency. When there are not a plurality of sound sources having the maximum appearance frequency, the flow advances to step S61 to determine secondly that the sound source having the maximum appearance frequency is the indoor sound source. After that, the second judgment ends in step S70, and the sound source judgment ends in step S80.

If there are a plurality of sound sources with the maximum appearance frequency, the flow advances to step S62, based on a predetermined priority of sound source selection, the sound source having the highest priority among the sound sources having the maximum appearance frequency is called the indoor sound source. Determine. After that, the second judgment ends in step S70, and the sound source judgment ends in step S80. In this case, the priority of sound source selection is determined in the order of the air conditioner itself, the medium-use device group, the broadcast receiving device group, the dialogue, and the light-use device group. By determining the priority in this way, it was found from the inventor's examination result that the accuracy of sound source group selection is improved. In particular, it has been clarified that by selecting the broadcast receiving device group over the dialogue, most sound source selections are made appropriately and the accuracy of the sound source group selection is further improved.

In addition, in the present Example, the 2nd determination was made based on the sound source with the largest appearance frequency from the result of a 1st determination as an indoor sound source. However, the result of the primary determination may be appropriately weighted (for example, weighted in close order in time series, etc.) to be integrated, and the second determination may be performed by using the sound source group having the maximum integration result as the indoor sound source. .

The determination threshold for determining the sound source from the sampling result will be described with reference to FIGS. 14 and 15. 14 is an explanatory diagram of correction by ambient sound. 15A is an explanatory diagram of correction by ambient sound, and FIG. 15B is an example of correction of a determination threshold value.

Even when the occupants are quiet, various sounds such as clocks and pumps of aquarium fish tanks are generated indoors. Therefore, in the case of controlling the air conditioner based on the signal from the sound sensor, it is necessary to consider the influence of the sound of the sound when the occupant is quiet and the sound of the air conditioner itself. For this reason, in the air conditioner of this embodiment, the sound when the occupant is quiet at the start of operation is determined by the method mentioned above.

The average of the sampling results is referred to as the "initial value", and is compared with the "reference value" (which is approximately equal to the average value of the sampling results when operating in the same environment) determined by the air conditioner itself. In the case of the reference value <initial value>, when the determination result of the sound source is the air conditioner itself, it is assumed that the environmental sound of the room other than the sound of the air conditioner itself affects the determination result even if the room is quiet. The determination threshold of each sound source is corrected. When the determination result of the sound source is a sound source group other than the air conditioner itself, it is determined that significant sound, which cannot be referred to as the air conditioner itself or the environmental sound, is generated, and the determination threshold value of each sound source is not corrected. When the result of comparing the initial value with the reference value is "reference value> initial value", since each sound source can be identified and determined by the current determination threshold value, the determination threshold value of each sound source is not corrected.

Next, the correction of the sound source determination threshold value will be described with reference to FIG. 14. The operation of the air conditioner is started in step S100. If it is determined in step S101 that the air conditioner is installed and is the first operation, the reference environmental sound measurement period (in the embodiment, operating or stopping in a quiet state by operating or stopping in a quiet state to measure the reference environmental sound) 1 minute), and the original value stored for each time slot in the storage device of the air conditioner is substituted into the reference value.

In step S105, correction of the sound source determination threshold is started. In step S106, the reference environmental sound is measured by the sound sensor in the reference environmental sound measurement period, and the initial value is set. In step S107, the reference value of the current time zone is read, and in step S108, the reference value and the initial value are compared. If the initial value is equal to or less than the reference value (reference value> initial value), the initial value is substituted into the reference value of the current time zone in step S111, and the sound source determination threshold value correction is terminated in step S120 without correcting the determination threshold value.

If the initial value exceeds the reference value in step S108 (reference value <initial value), the flow advances to step S115 to determine whether the type of sound source is the air conditioner itself, based on the sampling result obtained by measuring by the sound sensor in the reference environmental sound measurement period. Determine. If it is determined that the type of the sound source is other than the air conditioner itself, the sound source determination threshold value correction is terminated in step S120 without correcting the determination threshold value as shown in Fig. 15A. If it is determined in step S115 that the type of sound source is the air conditioner itself, the flow advances to step S116 to correct the determination threshold value as shown in FIG. Proceeding to step S117, as shown in Fig. 15B, the initial value is substituted into the reference value of the current time period, and the sound source determination threshold value correction is completed in step S120.

Next, the operation of the pyroelectric infrared sensor will be described with reference to FIG. 16. It is explanatory drawing of reaction detection division judgment.

A pyroelectric infrared sensor is used in combination with a Fresnel lens to take a change in the amount of infrared light from the room. The response of the pyroelectric infrared sensor is large when there is active movement in the room, and the response of the pyroelectric infrared sensor is small. The signal from the pyroelectric infrared sensor is amplified by a bandpass filter that extracts human motion, digitized and transmitted to a microcomputer embedded in the controller.

The microcomputer samples this digital signal for a sampling period (60 seconds in the embodiment) at a predetermined sampling period (10 ms in the embodiment). The reaction detection ratio Px is obtained by calculating the ratio of reaction detection data among the sampled data. When this reaction detection ratio Px is less than the positive determination threshold Pb which determines whether the quantity of movement in a room is small, the detection division of reaction is divided into reaction small. When the reaction detection ratio Px is equal to or greater than the motion determination threshold Pv for determining whether the amount of movement in the room is large, the detection classification of the response is classified into the response zone. When the reaction detection ratio Px is equal to or greater than the positive determination threshold value Pb and less than the determination threshold value Pv, the detection classification of the reaction is classified into middle of the reaction.

Next, a method of subdividing and determining the amount of activity by the combination of the pyroelectric infrared sensor and the sound sensor will be described with reference to FIGS. 17 and 18. 17 is a combination activity determination chart. 18 is an explanatory diagram of activity determination.

The activity amount determining unit combines the detection division of the above-described reaction obtained at the same time and the result of the sound source determination to subdivide the activity amount of the occupant as shown in FIG. 17. Thus, even if the detection classification of reaction is the same, when the sound source is a warm sense fluctuation large sound source group accompanying the activity of the occupant, the amount of activity is determined to be larger than when the sound source is a warm sense fluctuation noise source group which is not related to the activity of the occupant. Thereby, since the activity amount is divided into five to six steps from the conventional three steps, it is possible to make the control more delicate than the conventional one.

In the example of FIG. 17, when the detection division of the reaction by the pyroelectric infrared sensor is the response zone, and the type of the sound source is the warm-sensing fluctuation large-sound source group consisting of the heavy-use device group, the dialogue and the light-use device group, the amount of activity is maximized. do. In addition, when the detection division of the reaction by the pyroelectric infrared sensor is a reaction tablet, and the sound source is a warm sense fluctuation noise source group consisting of the air conditioner itself and the broadcast receiving device group, the amount of activity is minimized. In the other part of the matrix, the magnitude of the amount of activity in the same response detection category in the matrix is "thermal fluctuation noise source group ≤ warm fluctuation fluctuation loud source group", and the magnitude of the activity in the same sound source group is "reaction positive <response <response vs. Decide the amount of activity to be In this way, by subdividing the amount of activity, estimating the amount of activity of the occupants, and carefully controlling the air conditioner, the air conditioner can be energy-saved and operated while considering comfort.

Such determination of the amount of activity is repeated a plurality of times as shown in FIG. With respect to the result of the determination of the plurality of times, the closer to the time series, the more weighted and integrated. Based on the integration result, it is determined that the division of the maximum amount of activity is the amount of activity of the occupants.

In Fig. 17, a method of simply determining the amount of activity as two steps is adopted. However, for example, by further subdividing the temperature-sensing fluctuation large sound source group, the magnitude of the activity amount in the same response detection division is ordered as "the temperature-sensing fluctuation noise source group ≤ conversation ≤ light use device group ≤ heavy use device group". You may want to divide into large amounts of activity. The degree of subdivision is determined according to how accurately the thermal sense of the occupant can be estimated from various sensors.

As described above, the air conditioner is controlled based on the information of the granular activity amount. In other words, when the amount of activity of the occupants is small at the time of cooling, the occupants are quiet and the metabolism is inactive, so the body has less heat, and the warmth of the occupants is changed to the cold side. In this case, even if the room temperature is slightly raised, the comfort remains within the allowable range, and thus the energy saving operation is achieved by increasing the room temperature slightly. On the other hand, when the amount of activity of the occupants is large at the time of heating, since the occupants are actively moving and the metabolism is active, the body heat is increased, and the warming sense of the occupants is also changed to the hot side. In this case, even if the temperature is slightly lowered, the comfort remains within the allowable range, so that the energy saving operation is achieved by lowering the temperature slightly.

Next, adjustment of intake air temperature is demonstrated using FIG. 19 is an example of a temperature shift value.

Since the air conditioner spots around the user of the air conditioner to conserve energy, the temperature can be detected at the position of the remote controller located near the user, and the air conditioner can be operated around the space where the user is located. At this time, the heating capacity and the cooling capacity of the air conditioner are controlled based on the intake air temperature and the set temperature of the air conditioner. However, the intake air temperature of the air conditioner installed in the high place of the room is higher than the temperature of the living space from the floor of the room where the user is to the face height. In order to correct this temperature difference, the air conditioner is controlled so that the intake air temperature approaches the additional set temperature at which a predetermined value (temperature shift value) is added to the set temperature. As a predetermined value, although it changes with the structure of an air conditioner, and operation modes, such as heating and cooling, it is about -1-5 degree | times.

However, in general, even in the living space, the temperature is different in the center of the room and the window side. Therefore, as described above, even if the air conditioner is controlled to bring the intake air temperature closer to the additional set temperature, the surroundings of the user may not be comfortable. In such a case, it is necessary for the user to search for and select a comfortable state (temperature) by operating the set temperature up and down using the remote controller.

When the room changes from a comfortable state to an unpleasant state, the user recognizes that it is outside the allowable comfort range and resets the setting of the air conditioner. However, every time, the setting of the air conditioner must be changed, which is cumbersome. At that time, if the setting of the air conditioner is changed more than necessary (if the set temperature at the time of cooling is set too low / the set temperature at the time of heating is made too high), the power consumption increases, and energy saving operation is not achieved. On the other hand, even if it changes from an unpleasant state to a comfortable state, it is difficult to recognize that it is a comfortable range at the time of entering into a comfortable range, and eventually the room may change from a comfortable state to an unpleasant state.

In the present invention, the activity amount of the occupant is subdivided from the detection result of the pyroelectric infrared sensor and the sound sensor as above, and the above-described temperature shift value is delicately corrected while considering the comfort of the occupant according to the amount of the segmented activity. This eliminates the trouble of the occupants changing the settings each time, and enables energy saving operation of the air conditioner.

Next, the operation of the radiation sensor will be described with reference to FIG. 20. FIG. 20A is an explanatory diagram of the radiation amount determination, and FIG. 20B is a block diagram of the radiation amount determination. Using a thermopile as a radiation sensor, the amount of infrared rays from the floor, walls, and the like in the room is measured to obtain a radiation temperature. When the walls and the floor of the room are warmed by daylight or the temperature is separated from the room temperature by another air conditioner or the like, the heating sense of the occupant is changed. Therefore, the room temperature is changed to perform energy saving operation.

The signal from the radiation sensor is properly amplified and digitized through a bandpass filter and transmitted to the microcomputer. The microcomputer samples this digital signal during a sampling period at a predetermined sampling period and combines the signal from the room temperature sensor to calculate a temperature difference between the radiation temperature and the room temperature. This sampling and calculation are performed a plurality of times, and the average value of the plurality of times is calculated to be the radiation temperature difference.

In the case of cooling, when the radiation temperature difference becomes negative, the temperature of the wall and the floor is lower than room temperature, and the thermal sense of the occupant changes to the cold side. Therefore, the comfort can be maintained even if the room temperature is slightly increased, and the energy saving operation is achieved by increasing the room temperature slightly. In the case of heating, when the radiant temperature difference becomes positive, the temperature of the wall and the floor is higher than room temperature, and the warmth sense of the occupant changes to the hot side. Therefore, even if room temperature is raised slightly, comfort can be maintained, and energy saving operation becomes so much that room temperature is slightly lowered.

On the other hand, airflow also has a great influence on a person's sense of heat. Even at the same temperature, when the airflow is strong, the thermal sensation is increased than when it is weak, and when the airflow is cool, it feels cooler, and when the airflow is warm, it feels warmer.

The air conditioner of this embodiment has a function of detecting the position of the remote controller, and can recognize the distance between the air conditioner and the remote controller. Using this function, the state of the airflow near the remote controller where the user is located is estimated. If the position of the remote controller is far from the air conditioner, the airflow from the air conditioner is weak, and a user near the remote controller also feels a weak airflow from the air conditioner. On the contrary, when the position of the remote controller is close to the air conditioner, the airflow from the air conditioner is strong, and even a user near the remote controller feels a strong airflow from the air conditioner and strongly cools and cools the air from the air conditioner. I feel it. That is, in the case of cooling, the comfort remains within the allowable range even if the room temperature is slightly raised, and in the case of heating, the comfort stays within the allowable range of the comfort.

By utilizing the function of detecting the position of the remote controller of the air conditioner of the present embodiment, a function of sending air that is air-conditioned toward the direction in which the remote controller is located, and a function of directing the wind in a direction other than the direction in which the remote controller is located Equipped. As a result, it is possible to comply with the request for intensively contacting the cold and hot air initially entering the room from an external non-air-conditioning space. In addition, direct wind contact may be avoided, but the gentle wind around the area where the remote controller is located may comply with the demands of those who expect mild air conditioning.

In addition, the air conditioner of this embodiment is equipped with a temperature sensor in the remote controller, detects the temperature around the remote controller, and is controlled so that the temperature around the remote controller becomes a set temperature. In this case, when the air conditioner is operated under a small load condition, the ambient temperature around the remote controller may be too cold or too warm. This occurs when the air conditioner is not balanced well due to the installation position of the air conditioner, the arrangement of the furniture, the setting of the wind direction, or the local cold or warm gap wind or heat load. Even in such a case, when the ambient temperature of the remote controller is too lower than the set temperature at the time of cooling, the comfort remains in the permissible range even if the temperature is slightly increased. Therefore, the air conditioner is raised to make energy saving operation. In the case of heating, when the ambient temperature of the remote controller is excessively higher than the set temperature, the comfort remains in the permissible range even if the temperature is slightly raised, so the air conditioner is lowered slightly to make energy-saving operation.

In addition, when the amount of activity of the occupants is large, it is likely that the occupants are moving around the room and not near the remote controller. In general, since the amount of activity is directly related to the fever in the body, the effect on the sense of heat is great. However, the airflow only affects the dissipation of heat generated in the body, and at a wind speed of about 1 m / s such as air conditioning, the effect on the thermal sensation is small compared to the effect of the amount of activity. In addition, room temperature also only affects the dissipation of heat generated in the body, and at a change of room temperature within several degrees such as air conditioning, the effect on the thermal sensation is smaller than the effect of the amount of activity. For this reason, when the amount of activity is more than a predetermined division (in the embodiment, the amount of activity "large" or more), it is very important to control to change the target room temperature according to the remote controller position or the temperature difference between the remote controller ambient temperature and the set temperature. There is no.

The air conditioner of the present embodiment includes an infrared sensor for detecting the amount of movement of the occupant, a sound sensor for detecting the sound of the room, a setting unit for setting the set temperature of the room, and a control unit for controlling the operation. According to the detection result and the detection result of the sound sensor, it has an activity quantity determination part which determines the activity amount of a occupant, and changes the target value determined based on the set temperature based on the activity determination amount of the occupant determined by the activity quantity determination part. Thereby, the type of sound source is determined based on the detection result of the sound sensor, and the amount of activity of the occupant is determined by combining the determined type of sound source and the amount of movement of the occupant, whereby the amount of activity of the occupant can be determined with high accuracy. Therefore, the air conditioner can be more appropriately controlled according to the amount of activity of the occupants, so that the air conditioner can be operated more energy-saving while considering the comfort of the occupants.

In addition, the air conditioner of the present embodiment includes an infrared sensor for detecting the amount of movement of the occupant, a sound sensor for detecting the sound of the room, a setting unit for setting the set temperature of the room, and a control unit for controlling the operation. According to the type of the sound source determined based on the detection result of the sensor and the detection result of the sound sensor, it has an activity amount determination unit for determining the activity amount of the occupants, and based on the activity determination amount of the occupant of the occupant determined by the activity amount determination unit, Change the set target value based on that. As a result, it is possible to determine whether the type of sound source is a warm-sensing fluctuation loud source or a warm-sensing fluctuation noise source, and the amount of activity of the occupant can be determined with high accuracy according to the type of the determined sound source and the magnitude of the movement of the occupant. Therefore, the air conditioner can be more appropriately controlled according to the amount of activity of the occupants, so that the air conditioner can be operated more energy-saving while considering the comfort of the occupants.

In addition, the air conditioner of the present embodiment has a suction temperature detector for detecting the intake air temperature of the compressor, the indoor blower and the air conditioner, and when the heating, the activity determination amount is larger, the target temperature is changed to a lower temperature, the cooling, the activity The smaller the determination amount, the more the target temperature is changed to a higher temperature, thereby controlling at least the rotational speed of the compressor or the rotational speed of the blower so that the intake air temperature becomes the target temperature. Based on the detection result of the sound sensor and the detection result of the infrared sensor, the amount of activity is discriminated in multiple stages. When the activity amount of the occupant is large, the activity shift value is decreased, and when the activity amount of the occupant is small, the activity shift value is increased. This is added as the temperature shift value to the set temperature, and the compressor rotation speed and the blower rotation speed are changed to adjust the compressor capacity, the blowing temperature, the blowing air volume, and the like so that the intake air temperature becomes the target temperature which is the additional set temperature. Thereby, the intake air temperature is adjusted to be lower than the set temperature as the amount of activity is higher during heating, and the intake air temperature is adjusted to be higher than the set temperature as the amount of activity is lower during cooling. Therefore, the air conditioner can be more appropriately controlled according to the amount of activity of the occupants, so that the air conditioner can be operated more energy-saving while considering the comfort of the occupants.

In addition, the air conditioner of the present embodiment includes an infrared sensor for detecting the amount of movement of the occupant, a sound sensor for detecting the sound of the room, a setting unit for setting the set temperature of the room, and a control unit for controlling the operation. According to the type of the sound source determined based on the response classification of the infrared sensor classified based on the detection result of the sensor and the detection result of the sound sensor, the activity amount determination unit determines the activity amount of the occupant, Based on the activity judgment amount, the predetermined target value is changed based on the set temperature. The infrared rays reaching the pyroelectric infrared sensor from the room are sampled for a predetermined time at a predetermined sampling period, and the ratio Px of the number of times of detection of the infrared rays is calculated to be a sampling result. When this sampling result is less than a positive determination threshold, the division (detection division of a reaction) of the detection amount of reaction is divided into "reaction well". If the sampling result is equal to or greater than the positive determination threshold value, the sampling result is compared with the strong determination threshold value. When a sampling result is more than a strong determination threshold, the detection division of reaction is divided into "reaction steel." When the sampling result is less than the strong determination threshold, the detection division of the reaction is divided into "during reaction". In addition, it is determined whether the type of sound source is a warm sense fluctuation loud source or a warm sense fluctuation noise source. The amount of activity of the occupants is determined in another stage by combining the type of the determined sound source and the response detection category of the occupants. As a result, the air conditioner can be more appropriately controlled according to the amount of activity of the occupants, so that the air conditioner can be operated more energy-saving while considering the comfort of the occupants.

In addition, the air conditioner of the present embodiment has a compressor, an indoor blower, and a remote controller capable of bidirectional communication with the air conditioner main body, and the closer the position of the remote controller is from the air conditioner without operating the compressor, The smaller the activity determination amount, the smaller the rotation speed of the indoor blower is, and the air blowing operation is directed toward the remote controller. The air conditioner detects the remote controller position and directs it to the remote controller position, for example, by pressing a specific button on the remote controller, for example, when you want to blow a little air. It sends strong winds, and also the strong winds of the user's activity. By controlling in this way, it is possible to provide an appropriate cool feeling according to the user's activity by the energy-saving operation of the ventilation only.

In addition, the air conditioner of the present embodiment repeats the determination of the activity amount of the occupants in the activity determination unit a plurality of times, and the weight which is closer to the time series which is closer in time series to the activity amount of the occupants determined in each time is increased. Based on the integrated value obtained by integrating the meeting decision result, the amount of activity of the occupants is determined second. As a result, since the determination of the activity amount of the occupant in the activity amount determination unit is repeated a plurality of times, a long-term change in the room can be reflected, and malfunctions based on short-term changes can be avoided. In addition, since the primary determination is made for each primary determination section to grasp the indoor situation, the indoor information can be leveled and captured accurately without biasing the information. In addition, the data in the primary determination section is used only for the primary determination, and selects a unique result in the primary determination. Therefore, even when the data of a plurality of primary determination candidates are antagonistic within the primary determination section and the result of the primary determination changes, the secondary determination based on the result of the plurality of primary determinations is the predominant primary. It remains stable as a judgment candidate. In this way, while improving the accuracy of the determination and further lengthening the determination period (it does not change the determination result repeatedly in a short time), the comfort of the room is not impaired. In addition, since the first decision result closest to the present is most important, when a new activity is temporarily performed but another activity is performed immediately, the result of the first decision in the current activity with emphasis is accumulated and becomes a second decision. . In this way, it is possible to reliably capture the tendency of the change in the amount of activity, to appropriately grasp the amount of activity of the occupants, and to perform energy-saving operation while considering comfort with fine control.

In addition, the air conditioner of the present embodiment, the activity amount determining unit divides the type of the sound source into a group of the temperature-sensitive variable sound source and a group of the temperature-sensitive variable noise source, and determines the activity determination amount when the type of the sound source belongs to the group of the temperature-sensitive variable sound source, Response division of infrared sensor is the same division and shall be more than activity judgment amount when kind of sound source belongs to group of warm sense fluctuation noise source. In consideration of the increase in sound accompanying the activity when the activity of the occupants becomes active, even if the movement amount of the occupants separated based on the detection result of the infrared sensor is the same, the activity of the occupants becomes more active in the case of the warmth fluctuation large sound source. As the sense is shifted to the hot side, the activity judgment amount is increased to lower the air conditioning temperature. Thereby, energy saving can be carried out by delicate operation, considering comfort.

In addition, the air conditioner of the present embodiment includes the air conditioner itself and the broadcast receiving device group in the group of the warmth fluctuation noise sources, and includes the heavy-use device group and the conversation in the group of the warmth fluctuation noise sources. That is, in the case of the air conditioner itself and the broadcast receiving device group which do not involve the occupant, the type of sound source is classified into a warm-sensing fluctuation noise source. A group of heavy-use devices such as vacuum cleaners and health promotion devices that accompany the inmates' activities, and a cooking appliance such as juicers and mixers that do not involve large activities of the occupants, and equipments for use such as dryers and shavers, In the case of conversation between the occupants, the type of sound source is divided into a warm sense fluctuation loud source. By dividing in this way, it is possible to appropriately determine the amount of activity of the occupants and to operate energy-saving while taking into consideration the comfort by fine control.

In addition, the air conditioner of the present embodiment includes a television and a radio in the broadcast receiving device group and an electric vacuum cleaner in the heavy-use device group.

When the occupant is quietly listening to the television or radio, the sound in the room does not accompany the activity of the occupant. Therefore, it is not necessary to control the air conditioner in accordance with the sound of the television or the radio. For this reason, the sound of a television or a radio is divided into the broadcast receiving device group of a thermal fluctuation noise source group. In addition, when the occupant is using a vacuum cleaner, the occupant is doing a great job, so it is necessary to appropriately control the air conditioner. For this reason, the vacuum cleaner is classified into a heavy-use device group of the warmth fluctuation large sound source group. By dividing in this way, it is possible to appropriately determine the amount of activity of the occupants and to operate energy-saving while taking into consideration the comfort by fine control.

Further, the air conditioner of the embodiment separates the detection result of the sound sensor into a plurality of frequencies, and determines the sound source based on a combination of the number of detections per frequency band and the frequency band. Thereby, the kind of sound source can be determined reliably, and the accuracy of determination of the activity amount of the occupant can be further improved in combination with the detection result of the infrared sensor which detects the movement amount of the occupant. Therefore, the air conditioner can be more precisely controlled in accordance with the amount of activity of the occupants.

In addition, the air conditioner of this embodiment includes a frequency band of 1 to 4 kHz and a frequency band of 5 to 12 kHz as a plurality of frequency bands. It is possible to distinguish between the voice of a person who contains a lot of low frequency (1 to 4 kHz) sound and a mechanical sound such as a cleaner that includes a lot of high frequency (5 to 12 kHz) sound. It becomes possible. Thereby, the kind of sound source can be determined reliably, and the accuracy of determination of the activity amount of the occupant can be further improved in combination with the detection result of the infrared sensor which detects the movement amount of the occupant. Therefore, the air conditioner can be more precisely controlled in accordance with the amount of activity of the occupants.

In the air conditioner of this embodiment, the active amount determining unit separates the detection result of the sound sensor into a plurality of frequencies, samples the predetermined time at a predetermined sampling period, and obtains the ratio of the number of times of detection of the sound for each frequency band as the sampling result. Then, the type of sound source is determined based on the sampling results of the plurality of times. As a result, it is possible to distinguish a voice of a person including a lot of low frequency sound and a machine sound such as a cleaner including a lot of high frequency sound, thereby making it possible to reliably determine the type of sound source. In addition, since sampling is performed a plurality of times, it is possible to reflect a long-term change in the type of the sound source in the room, thereby reducing malfunctions based on short-term changes. In addition, since the time until the determination is divided into a plurality of sampling sections and the sampling result is obtained for each sampling section to grasp the situation in the room, the information in the room can be leveled and grasped, thereby eliminating the bias of the information and accurately grasping the information. have. In addition, since the data in the sampling section is used only for the sampling result of the section, and only one sampling section yields a unique sampling result, the magnitude, variation or degree of concentration of the plurality of sampling results up to the determination is characterized by the type of sound source. This provides information useful for determining the type of sound source. In this way, the trend of change in the type of sound source is reliably grasped and combined with the detection result of the infrared sensor which detects the movement amount of the occupant, the activity amount of the occupant is appropriately determined, and the air conditioner is adjusted in accordance with the activity amount of the occupant. It can control more precisely and can drive energy-saving, considering comfort.

In addition, the air conditioner of this embodiment determines that the type of sound source is the air conditioner itself when all sampling results are less than the air conditioner determination threshold set for every frequency band in all frequency bands. Thereby, by using the value a little larger than the sampling result at the time of operating only the air conditioner itself as an air conditioner determination threshold value, the sound which generate | occur | produces in the room other than the sound which the air conditioner itself generate | occur | produces is produced previously. It can be seen that the sound is a little environmental sound (such as a clock or a pump of an aquarium fish tank), and the sound source can be determined as the air conditioner itself. As a result, the sound source can be accurately identified and combined with the detection result of the infrared sensor, to appropriately determine the amount of activity of the occupants. Therefore, the air conditioner can be more precisely controlled in accordance with the amount of activity of the occupants, and energy-saving operation can be performed while considering comfort.

Further, the air conditioner of the present embodiment adds the type of sound source to each frequency band when the entire sampling result is equal to or greater than the heavy-use device determination threshold, and the difference between the average value of the sampling result and each sampling result is within the heavy-use device determination range. It judges that it is a use apparatus group. Thereby, in order to support the user's power or speed, it is possible to determine a heavy-use device such as a cleaner which emits a relatively loud driving sound and a continuous sound at a constant size. As described above, when a loud sound is generated by a certain level or more and the sound is continuously generated, it is assumed that the occupant is using a device using a motor such as a vacuum cleaner to perform large household chores. . The value of the heavy-use apparatus determination range is determined beforehand using a value slightly smaller than a large negative sampling result such as a vacuum cleaner as the heavy-use apparatus determination threshold. Thereby, the kind of sound source can be grasped correctly, and it can combine with the detection result of an infrared sensor, and can determine appropriately the activity amount of a occupant. Therefore, the air conditioner can be more precisely controlled in accordance with the amount of activity of the occupants, and energy-saving operation can be performed while considering comfort. In addition, in the present embodiment, it is determined that the difference between the average value of the sampling results and the respective sampling results is within the range of the heavy-use device determination that the sound has a constant magnitude. However, as another judging method, the difference between the average value of the sampling result and the minimum value of the sampling result is within the range of the heavy-use device determination so as not to cause a false judgment by a sudden sound, for example, and the average value of the sampling result is the average of the heavy-use device. You may determine so that it may be below a threshold.

In the air conditioner according to the present embodiment, the number of times that the sampling result is equal to or greater than the broadcast receiving device determination threshold is equal to or greater than the lower limit count of the broadcast receiving device and less than or equal to the upper limit count of the broadcast receiving device for each frequency band. When the continuation of meetings that is equal to or larger than the reception device determination threshold is interrupted midway, the type of sound source is determined to be the broadcast reception device group. As a result, it can be distinguished from the medium-use device or the light-use device by interruption of several seconds or more that occurs in the voice of a broadcast receiving device such as a television or a conversation between the occupants. In addition, the voice of the broadcast receiving device includes a high frequency sound (such as music or effect sound) that does not occur in the conversation between the occupants. Accordingly, it is possible to discriminate between the voice of the broadcast receiving device and the conversation between the occupants. In addition, it is common to have a long pause of several tens of seconds in the conversation between the occupants, and not to have such a long interruption in the voice of the broadcast receiving device, so that the accuracy of sound discrimination can be further improved. In this way, the broadcast receiving device determination threshold value, the lower limit count threshold value, and the upper limit count threshold value are appropriately determined, and by detecting that the continuation of the meeting that is equal to or greater than the determination threshold value is interrupted in the middle, the type of sound source is accurately determined and the In combination with the detection result, the amount of activity of the occupants can be appropriately determined, the air conditioner can be more precisely controlled in accordance with the amount of activity of the occupants, and energy-saving operation can be performed while considering comfort.

In the air conditioner of this embodiment, for each frequency band, the number of times in which the sampling result is equal to or greater than the conversation determination threshold is equal to or less than the lower limit number of thresholds of the conversation, and is equal to or less than the upper limit number of times of the conversation. If this is interrupted in the middle, it is determined that the type of sound source is conversation. Thereby, the conversation determination threshold, the lower limit count threshold value, and the upper limit count threshold value are set to appropriate values different from the broadcast reception device, thereby identifying the conversation with the broadcast reception device. In this way, by accurately grasping the type of the sound source, in combination with the detection result of the infrared sensor, the activity amount of the occupant is appropriately determined, and the air conditioner is more delicately controlled in accordance with the activity amount of the occupant, Can drive energy saving.

In addition, the air conditioner of the present embodiment repeats the determination of the sound source a plurality of times, and determines the sound source group having the maximum appearance frequency in the plurality of determinations as the sound source in the room. Thereby, since the time until the final secondary determination is lengthened, long-term changes in the room can be reflected, and malfunctions based on short-term changes are reduced. In addition, since the time until the second determination is divided into a plurality of primary determination sections, and the primary determination is made for each primary determination section to grasp the situation of the room, the indoor information can be grasped and grasped to eliminate the bias of the information. Accurately grasp the information. In addition, the data in the primary determination section is used only for the primary determination, and selects a unique result in the primary determination. Therefore, even when the data of a plurality of primary determination candidates are antagonistic within the primary determination section and the result of the primary determination is changed, the secondary determination based on the result of the plurality of primary determinations is superior to the primary determination candidate. It remains stable. In this way, since the second judgment is made at a time interval in which a sufficient judgment section capable of making a reliable judgment and a control interval that can ensure a gentle change that does not impair the comfort of the room are compatible, the comfort of the room is impaired. There is no case. Delicate control enables energy-saving operation while considering comfort.

In addition, the air conditioner of this embodiment repeats the determination of the sound source a plurality of times, weights the determination result, integrates the weighted result for each group of the sound source, and the group of sound sources having the maximum integrated value. It is determined that the type of sound source in the room. As a result, as described above, the indoor information can be grasped and grasped, and the information can be grasped accurately without the bias of the information. In addition, by giving an appropriate weight to each decision result, the air conditioner can be controlled more appropriately. For example, in the case where the weight is given to the times that are closest in time series, the first decision result closest to the present is most important. Therefore, when a new activity is temporarily performed but another activity is performed immediately, the result of the primary determination in the weighted current activity is integrated to become the secondary determination. In this way, it is possible to reliably capture the tendency of the change in the amount of activity, to appropriately grasp the amount of activity of the occupants, and to perform energy-saving operation while considering comfort with fine control.

In the air conditioner of the present embodiment, the activity amount determining unit defines a selection order in a group of a plurality of sound sources, and when there are a plurality of groups of sound sources having a maximum appearance frequency or integrated value, the group of sound sources having a high selection order is indoors. It is determined that the type of sound source is. Thereby, energy saving operation is performed continuously without being controlled by the air conditioner, air conditioning is interrupted, and comfort is not impaired.

In addition, the air conditioner of this embodiment is a group of indoor sound sources determined by the activity determination unit, and includes an air conditioner itself, a heavy-use device group, a broadcast receiving device group, and a conversation. By discriminating the types of sound sources in this way, it is possible to grasp the activities of the occupants in more detail and accurately. Therefore, the air conditioner can be operated in consideration of comfort and energy saving.

In addition, the air conditioner of the present embodiment sets the selection order of the broadcast receiving device group to be higher than the selection order of the conversation. In the case where the appearance frequency or the integrated value is tied and maximized in the dialogue with the broadcast reception device group, the broadcast reception device group is determined as the kind of sound source. It is difficult to distinguish between human conversation and real conversation by the broadcast receiving device group. However, when the frequency of appearance or the integrated value is tied, it is possible to include a high frequency sound (music or sound effect) that does not occur in the actual conversation, in which case it is determined that the type of sound source is a group of broadcast receiving devices. It is reasonable. In this way, by selecting the selection order, it is possible to reasonably determine the type of the sound source. Therefore, in combination with the detection result of the infrared sensor, the amount of activity of the occupants can be grasped, and energy-saving operation can be performed with consideration for comfort with delicate control.

In addition, the air conditioner of the present embodiment includes an infrared sensor for detecting the movement amount of the occupant, a sound sensor for detecting the sound of the room, a setting unit for setting the set temperature of the room, and a control unit for controlling the operation. Based on the detection result of the sensor, a determination threshold for determining the type of sound source is formed, and the determination is made according to the reference environmental initial value which is the detection result of the sound sensor in the reference environmental sound measurement period in the room where the air conditioner is installed. A threshold correction unit for correcting the threshold value, and an activity amount determination unit for determining the activity amount of the occupants according to the detection result of the infrared sensor and the detection result of the sound sensor, and based on the activity determination amount of the occupant determined by the activity amount determination unit. The target value is changed based on the set temperature. Thereby, the sound which generate | occur | produces at the time of operation | movement or stop of an air conditioner can be grasped | ascertained in the room which installed the air conditioner. At the time of air conditioner operation, the sound of the air conditioner itself, the clock which generate | occur | produces even when there is no user, the sound of the circulation pump of an aquarium fish tank, etc. are detected. In addition, when the air conditioner is stopped, a clock, a sound of a circulation pump of an ornamental fish tank, and the like are detected. Specifically, the detection value (hereinafter referred to as the "reference environmental initial value") of the sound sensor for a predetermined time (for example, one minute) during the predetermined time or the air conditioner stop from the air conditioner operation start is compared with the reference value. do. In the case of the first operation or stop after the air conditioner is installed, the reference value is a detection value (hereinafter referred to as the reference environmental initial value) of the sound sensor during operation or stop recorded in the storage element of the controller in the manufacturing step as a reference value. use. Usually, it becomes a reference value <initial value. In the case of "reference environment initial value ≥ reference environment initial value", the determination threshold value is not corrected. When the determination threshold value is corrected from the result of the air conditioner operation, and when the sampling result of the sound sensor indicates that the type of the sound source is the air conditioner itself, the determination threshold value for determining the type of the sound source is corrected. . When the sampling result of the sound sensor indicates that the type of the sound source is other than the air conditioner itself, it indicates that a conversation other than the air conditioner itself, or the sound of the television, etc. are detected. The decision threshold is not corrected. Further, in the case of correcting the determination threshold value from the result during the air conditioner stop, and in the case of "standard environmental initial value ≤ reference environmental initial value + standard environmental tuning fork", the determination threshold for determining the type of sound source is corrected. Here, the standard environmental tuning fork is a value representing the width of the deviation of the environmental sound, and is recorded in advance in the storage element of the controller in the manufacturing step. In the case of "reference environmental initial value + standard environmental tuning fork <reference environmental initial value", dialogue threshold other than air conditioner itself or sound of TV are detected, and judgment threshold is corrected because it is not driving in quiet state I never do that. Thus, by correcting the determination threshold value for determining the type of the sound source, it is possible to appropriately determine whether the type of the sound source is the type of the warmth fluctuation loudness source or the warmth fluctuation noise source in accordance with the sound environment of the room in which the air conditioner is installed. . Therefore, in combination with the detection result of the infrared sensor, the amount of activity of the occupants can be determined with high accuracy, and it is possible to contribute to energy saving while considering comfort with fine control.

In addition, the air conditioner of this embodiment is a case where it is determined that the reference environmental initial value is more than a predetermined reference value and the type of sound source is the air conditioner itself, or the reference environmental initial value is equal to or less than this reference value plus a predetermined standard environmental tuning fork. In that case, the decision threshold is corrected. Since the detection result of the sound sensor during the operation or stop in the quiet state can be obtained, the determination threshold for determining the type of sound source can be appropriately corrected. As a result, the type of sound source can be appropriately determined in accordance with the sound environment of the room where the air conditioner is installed. Therefore, the amount of activity of the occupants is grasped in combination with the detection result of the infrared sensor, and the comfort is controlled by the delicate control. Can drive energy saving.

In addition, when the determination threshold value is corrected, the air conditioner of the present embodiment changes the reference value to the reference environmental initial value to make a new reference value. Even if the acoustic environment of the room in which the air conditioner is installed is changed, a new reference value is set to suit the changed acoustic environment. This reference value is stored in the storage device and a new reference value is used instead of the previous reference value at the start of the next operation. By correcting the determination threshold value for determining the type of the sound source based on this new reference value, the type of the sound source can be appropriately determined. Therefore, in combination with the detection result of the infrared sensor, the amount of activity of the occupants can be grasped, and the energy saving operation can be performed while considering the comfort with finer control.

In addition, the air conditioner of this embodiment divides a day into a several time zone, changes only the reference value in the time zone where a reference environment initial value was detected, to a reference environment initial value, and sets it as a new reference value in this time zone. Even when the sound environment of the room where the air conditioner is installed varies depending on the time of day, the determination threshold is corrected to suit the changed sound environment, and the type of sound source can be determined appropriately, and the occupant is combined with the detection result of the infrared sensor. By grasping the amount of activity of the car, it is possible to drive energy-saving while taking care of comfort in delicate control.

In addition, the air conditioner of this embodiment includes an intake temperature detector for detecting intake air temperature, and changes a target value determined based on the set temperature based on the activity determination amount of the occupant determined by the activity determination unit, so as to intake air temperature. Is controlled to be the target temperature. The infrared rays reaching the pyroelectric infrared sensor indoors are sampled for a predetermined time at a predetermined sampling period, and the ratio Px of the number of times of detection of the infrared rays is calculated to be a sampling result. When this sampling result is less than the positive determination threshold value, the division (detection division of a reaction) of the detection amount of reaction is divided into "reaction well". If the sampling result is equal to or greater than the positive determination threshold, the sampling result is compared with the strong determination threshold. When a sampling result is more than a strong determination threshold, the detection division of reaction is divided into "reaction steel." When the sampling result is less than the strong determination threshold, the detection division of the reaction is divided into "during reaction". Further, it is determined whether the type of the sound source is a warm sense fluctuation loud source or a warm sense fluctuation noise source. The amount of activity of the occupants is determined in multiple stages by combining the type of the determined sound source and the response detection division of the occupants. In heating, the intake air temperature is adjusted to be lower than the set temperature as the amount of activity is higher, and in cooling, the intake air temperature is adjusted to be higher than the set temperature as the amount of activity is lower. As a result, the air conditioner can be more appropriately controlled according to the amount of activity of the occupants, so that the air conditioner can be operated more energy-saving while considering the comfort of the occupants.

In addition, the air conditioner of the present embodiment sets an activity shift value according to the activity determination amount, and controls the activity shift value to be a temperature shift value, and the intake air temperature to be an additional set temperature in which the temperature shift value is added to the set temperature. Based on the detection result of the sound sensor and the detection result of the infrared sensor, the amount of activity is determined in multiple steps such as maximum, large, medium, small, and minimum in large order, and the larger the amount of activity is determined as the smaller activity shift value. This is added to the set temperature as the temperature shift value and controlled so that the intake air temperature becomes the further set temperature. Thereby, the intake air temperature is adjusted to be lower than the set temperature as the amount of activity is higher during heating, and the intake air temperature is adjusted to be higher than the set temperature as the amount of activity is lower during cooling. Therefore, it is possible to operate energy saving by carefully controlling the air conditioner while considering comfort.

In addition, the air conditioner of the present embodiment, the infrared sensor for detecting the movement amount of the occupant, the sound sensor for detecting the sound of the room, the setting unit for setting the set temperature of the room, the control unit for controlling the operation, the compressor, A blower, a suction temperature detector for detecting the intake air temperature, and a remote controller capable of bidirectional communication with the air conditioner main body are configured to detect a relative position of the remote controller and the air conditioner main body, and detect the infrared sensor. The activity version of the in-patients determined by the activity determination unit having an activity amount determination unit for determining the amount of activity of the occupants according to the response classification of the infrared sensor classified based on the result and the type of sound source determined based on the detection result of the sound sensor. Determine the active shift value according to the fixed amount, determine the position shift value according to the position of the remote controller, By adding the value and position shift value to the set temperature as the target temperature of the intake air temperature, intake air temperature is controlled so that the target temperature. The infrared rays reaching the pyroelectric infrared sensor from the room are sampled for a predetermined time at a predetermined sampling period, and the ratio Px of the number of times of detection of the infrared rays is calculated to be a sampling result. When this sampling result is less than a positive determination threshold, the division (detection division of a reaction) of the detection amount of reaction is divided into "reaction well". If the sampling result is equal to or greater than the positive determination threshold, the sampling result is compared with the strong determination threshold. When a sampling result is more than a strong determination threshold, the detection division of reaction is divided into "reaction steel." When the sampling result is less than the strong determination threshold, the detection division of the reaction is divided into "during reaction". In addition, the amount of activity is determined based on the detection result of the sound sensor and the detection result of the infrared sensor, for example, in a large order, in multiple stages such as maximum, large, medium, small, and minimum, and the larger the activity, the smaller the activity shift value. It sets in this, and sets it as a temperature shift value, and adds to set temperature, and it controls so that intake air temperature may become an additional set temperature. Thereby, the intake air temperature is adjusted to be lower than the set temperature as the amount of activity is higher during heating, and the intake air temperature is adjusted to be higher than the set temperature as the amount of activity is lower during cooling. Further, the distance from the air conditioner to the remote controller is detected, and during cooling, the closer the distance from the air conditioner to the remote controller is, the larger the position shift value is added to the temperature shift value to adjust the intake air temperature. At the time of heating, the intake air temperature is adjusted by adding a small position shift value to the temperature shift value as the distance from the air conditioner to the remote controller is closer. Since the user of the air conditioner operates the air conditioner with the remote controller and then places the remote controller close to the air conditioner, the air is often located near the position where the remote controller is placed, and the air conditioner is close to the air conditioner. If the wind from the air conditioner is strongly felt and the distance from the air conditioner is far, the wind from the air conditioner is hardly felt. This is to feel the strength and weakness of the airflow affecting the thermal sensation, and the value obtained by adding the position shift value to the temperature shift value according to the strength and weakness of the airflow is set as the temperature shift value, even if the distance from the air conditioner is changed. Thus, the air conditioner is controlled so that the sense of heat approaches the comfort range. In this way, it is possible to contribute to energy-saving operation by controlling the air conditioner to operate the room temperature delicately and more appropriately according to the distance from the air conditioner while considering comfort.

Further, the air conditioner of the present embodiment detects the position of the remote controller to automatically direct the blowing wind direction to the remote controller position, and the second control to automatically deviate the blowing wind direction of the air conditioner from the remote controller position. In the first control, the position shift value is increased as the distance from the air conditioner is closer during the cooling operation, and the position shift value is increased as the position from the air conditioner is larger during the heating operation. In the case of the first control for automatically directing the blowing air direction of the air conditioner to the remote controller position, it is possible to comply with the request of intensively contacting the cold and hot air when entering from the outside. In addition, in the case of the second control that automatically diverts the air conditioner's blowing wind direction from the remote controller position, it is desired to avoid direct air, but with gentle wind from the surroundings, it is necessary to meet the needs of people who want a gentle air conditioner. Can follow. In the case of the first control, if the distance from the air conditioner is close, the wind from the air conditioner is strongly felt, and if the distance from the air conditioner is far, the wind from the air conditioner is hardly felt. This is to feel the strength and weakness of the airflow affecting the sense of heat, the closer the distance from the air conditioner at the time of cooling operation to the temperature shift value according to the strength and weakness of the airflow, the position from the air conditioner at the time of heating operation. The larger the position shift value is, the larger the temperature shift value is, and the air conditioner is controlled so that the sense of heat approaches the comfortable range even if the distance from the air conditioner is changed. In this way, fine control is performed in accordance with the distance from the air conditioner, whereby energy saving operation can be achieved.

In addition, the air conditioner of a present Example makes a position shift value 0 when activity amount is larger than a predetermined value. When the amount of activity of the occupant based on the detection result of the sound sensor and the detection result of the infrared sensor is maximum, for example, the position shift value according to the remote controller position is set to zero. It is highly likely that the occupants are moving around the room when the activity of the occupants is large and not staying at the remote controller. In this way, when it is determined that the amount of activity is greater than the predetermined value and that the occupants are not present at the position of the remote controller, it is not necessary to give the position shift value corresponding to the position of the remote controller. Instead of setting the position shift value to 0, the position shift value may be smaller than the position shift value when the amount of activity is small. By doing in this way, an air conditioner can be operated with the realistic position shift value according to the movement of the occupant when activity amount is large, and energy saving operation can be aimed at with comfort.

In addition, the air conditioner of a present Example makes a large correction shift value so that room temperature is low, and adds this correction shift value to a temperature shift value. As a result, in the heating operation, the intake air temperature is adjusted lower than the set temperature as the room temperature is higher, and in the cooling operation, the intake air temperature is adjusted higher than the set temperature as the room temperature is lower. Therefore, energy saving driving can be achieved while considering comfort.

In addition, the air conditioner of this embodiment is provided with a humidity sensor which detects indoor humidity, and it is set as a large correction shift value as the humidity is low, and this correction shift value is added to a temperature shift value. Accordingly, in the heating operation, the intake air temperature is adjusted lower than the set temperature as the humidity is higher, and in the cooling operation, the intake air temperature is adjusted higher than the set temperature as the humidity is low. Therefore, energy saving driving can be achieved while considering comfort.

In addition, the air conditioner of the embodiment includes a radiation temperature sensor that detects a floor surface temperature and a wall temperature of the room, and the smaller the "radiation temperature-(minus) room temperature" is set as a larger radiation shift value, and the radiation shift value is a temperature. Add to shift value. For example, by dividing "temperature difference", "temperature difference", and "temperature difference part" according to the value of radiation temperature-indoor temperature, the radiation shift value is made into small value as the radiation temperature-indoor temperature is large. Is added to the temperature shift value. Thereby, the intake air temperature is adjusted to be lower than the set temperature as the radiant temperature is higher during heating, and the intake air temperature is adjusted to be higher than the set temperature as the radiant temperature is lower in cooling. Therefore, energy saving driving can be achieved while considering comfort. By introducing the radiation temperature that affects the thermal sensation into the control of the air conditioner, the radiation shift value is changed in accordance with the difference between the radiation temperature and the room temperature, thereby enabling energy-saving operation by finer control.

In addition, the air conditioner of the present embodiment includes at least one of a room temperature sensor for detecting the temperature of the room, a humidity sensor for detecting the humidity of the room, a radiation sensor for detecting the floor temperature and the wall temperature of the room, and a calendar information function. According to at least one of room temperature, humidity, radiation temperature and room temperature, and calendar information, a positive correction shift value is added to a temperature shift value during cooling operation, and a negative correction shift value is added to a temperature shift value during heating operation. Thereby, in the heating operation, the intake air temperature is adjusted lower than the set temperature as the humidity or the radiation temperature is higher, and in the cooling operation, the intake air temperature is adjusted higher than the set temperature as the humidity or the radiation temperature is lower. Therefore, energy saving driving can be achieved while considering comfort.

In addition, the air conditioner of the present embodiment has a larger amount of clothing according to the calendar function, the closer to the severe period (for example, February), and the smaller the closer to the full moon (for example, August). I judge it. At this time, the larger the amount of wear, the smaller the correction shift value is added to the temperature shift value. Therefore, energy saving driving can be achieved while considering comfort.

Moreover, the air conditioner of a present Example sets the upper limit with the temperature shift value at the time of cooling operation as a positive value, and the lower limit with the temperature shift value at the time of heating operation as a negative value. By providing an upper limit to the temperature shift value at the time of cooling operation, an energy saving operation is calculated | required, and room temperature rises too much from a set temperature, and prevents deviation from comfortable air conditioning. By providing a lower limit to the temperature shift value even at the time of heating operation, the room temperature drops excessively from the set temperature to prevent deviation from comfortable air conditioning. This is because, when each correction shift value is added to the temperature shift value, the temperature shift value becomes too large and may deviate from the set temperature. In this manner, while maintaining comfort, energy-saving operation is achieved by adjusting the intake air temperature high during the cooling operation and by adjusting the intake air temperature low during the heating operation.

In addition, the air conditioner of a present Example determines both the upper limit value at the time of cooling operation of the temperature shift value, and the lower limit value at the time of heating operation, so that an activity amount is large. By pursuing energy saving operation, the upper limit and the lower limit of the temperature shift value are determined in accordance with the amount of activity of the occupants, thereby preventing the room temperature from being extremely separated from the set temperature and deviating from comfortable air conditioning. In this manner, while maintaining comfort, energy-saving operation is achieved by adjusting the intake air temperature high during the cooling operation and by adjusting the intake air temperature low during the heating operation.

In addition, the air conditioner of a present Example adds a zone shift value to a temperature shift value, when automatically controlling the blowing wind direction of an air conditioner toward a remote controller position. When receiving the air-conditioned comfortable wind, the intake air temperature is raised during the cooling operation and the intake air temperature is lowered during the heating operation to save energy. In this way, the energy-saving operation can be performed only when it is comfortable, so that energy-saving operation in consideration of comfort can be performed.

The air conditioner of this embodiment also includes a remote controller capable of bidirectionally communicating with the air conditioner main body using infrared rays as a communication medium, and the remote controller includes a remote controller ambient temperature sensor for detecting the remote controller ambient temperature. The ambient temperature information of the remote controller placed near the occupant is transmitted to the air conditioner main body, so that the temperature around the remote controller near the occupant can be adjusted to the set room temperature. As a result, the surroundings of the occupants are comfortably spotted, and energy saving operation can be achieved without consuming extra air conditioning energy.

In addition, the air conditioner of this embodiment adds a remote controller temperature shift value according to the value obtained by subtracting the set temperature from the remote controller ambient temperature to the temperature shift value. In the heating operation, the intake air temperature is adjusted to be lower than the set temperature as the temperature of the remote controller is higher, and in cooling operation, the intake air temperature is adjusted to be higher than the set temperature as the temperature of the remote controller is lower. Therefore, energy saving operation can be performed by carefully controlling the air conditioner while considering comfort of the occupants near the remote controller.

In addition, the air conditioner of this embodiment sets the upper limit with the activity shift value at the time of cooling operation as a positive value, and the lower limit with the activity shift value at the time of heating operation as a negative value. Intake air temperature from the set room temperature which is comfortable at the time of cooling operation is introduced by introducing factors of activity amount, room temperature, humidity, radiation, clothing amount, and airflow which affect the thermal sensation, and also the zone shift value and remote controller temperature shift value. By adjusting the height of high energy saving driving. At the time of heating operation, energy saving operation is aimed at by adjusting the intake air temperature low, considering the comfort similarly from the set room temperature which is a comfortable state. In addition, the energy saving operation is pursued to prevent an extreme deviation of room temperature from the set temperature and deviation from comfortable air conditioning. For this reason, the air conditioner which aims at power saving can be provided, considering comfort.

In addition, the air conditioner of the present embodiment calculates the temperature shift value a predetermined time, controls the intake air temperature to become the target temperature according to the calculated temperature shift value which is the average value of the predetermined predetermined temperature shift value, and sets the temperature shift value a plurality of times. When calculating the time, when the difference between the current activity judgment amount and the previous activity judgment amount becomes more than the predetermined amount, even before the predetermined time calculation of the temperature shift value is completed, to the current activity judgment amount instead of the determined temperature shift value. According to the corresponding temperature shift value, the intake air temperature is controlled to be the target temperature. By prolonging the time until the control is changed, the long-term change in the room is grasped, so that the erroneous change in the temperature shift value based on the short-term change is eliminated. In addition, since the time until the control is changed is divided into a plurality of temperature shift calculation sections, the temperature shift is calculated for each temperature shift calculation section, and the shape of the room is obtained. I can figure it out correctly. In addition, the data in the temperature shift calculation section is used only for the temperature shift calculation, resulting in a unique result in the temperature shift calculation. Therefore, even when the data of a plurality of temperature shift calculations are antagonized within the temperature shift calculation section and the result of the temperature shift calculation is changed, in the determined temperature shift value calculation based on the result of the plurality of temperature shift calculations, the prevailing temperature shift is performed. It remains stable as a result of the operation. In addition, when the temperature shift value in the arbitrary temperature shift calculation section has obviously increased, the temperature shift calculation section leading to the temperature shift calculation section is omitted, and based on the output in the temperature shift calculation section in which the temperature shift value has obviously increased. Compute a fixed temperature shift value. Therefore, the time until the change of the control is shortened and the immediateness of the control is secured. Normally, the control is changed at a time interval in which both the time until the change of the control which can grasp the indoor situation reliably and the control interval which can ensure the gentle change which does not impair the comfort of the room are focused on the certainty. Since the comfort of the room is not impaired. On the other hand, when the output of the temperature shift calculation section in which the time until the change of the control is divided into plural increases obviously changes, the control is immediately changed, thereby ensuring immediate response. In this way, the air conditioner can be controlled in a timely manner by shortening the time until the final determination as necessary, while maintaining the comfort of the room under normal gentle control, thereby achieving energy saving operation while considering comfort.

In addition, the air conditioner of this embodiment is provided with a wind direction plate which controls the blowing direction of blown air, and when a wind direction plate exists in the detection range of a radiation temperature sensor, it detected by the radiation temperature sensor based on the angle of the wind direction plate. Correct the radiation temperature. When detecting the radiation temperature within the predetermined detection range by the radiation temperature sensor, the wind direction plate of the air conditioner main body may exist within the detection range depending on the position of the radiation temperature sensor. Since the wind direction plate of an air conditioner main body exists in the vicinity of the blower outlet of an air conditioner, the temperature of a wind direction plate is influenced by the blowing air temperature of an air conditioner. In general, at the time of heating operation, the blowing air temperature of the air conditioner becomes a temperature higher than room temperature, but the temperature of the bottom surface and the wall surface is lower than the room temperature. Here, when the wind direction plate exists in the detection range of a radiation temperature sensor, since the temperature of a wind direction plate is higher than the temperature of an original bottom surface or a wall surface, it will detect that a radiation temperature is high. Moreover, when the ratio of the wind direction plate which occupies in the detection range of a radiation temperature sensor becomes large, the influence of the temperature of a wind direction plate will become large. Therefore, when the wind direction plate of an air conditioner main body exists in the detection range of a radiation temperature sensor, the error of detection of a radiation temperature can be corrected by correcting the detected radiation temperature according to the position of a wind direction plate.

In addition, the air conditioner of this embodiment is provided with a wind direction plate which controls the blowing direction of blown air, and when a wind direction plate exists in the detection range of a radiation temperature sensor, after moving a wind direction plate out of the detection range of a radiation temperature sensor, radiation The radiation temperature is detected by the temperature sensor. When the wind direction plate of the air conditioner main body exists in the detection range of a radiation temperature sensor, when detecting a radiation temperature, the wind direction plate is moved out of the detection range of a radiation temperature sensor once, and is not influenced by the temperature of a wind direction plate, It becomes possible to detect the radiation temperature.

In addition, the air conditioner of the present embodiment is an infrared sensor for detecting the amount of movement of the occupant, a sound sensor for detecting the sound of the room, a setting unit for setting the set temperature of the room, and a room for blowing air-conditioned air into the room A sound source having a blower and a control unit for controlling operation, having an activity amount determining unit for determining an activity amount of the occupant according to the type of sound source determined based on the detection result of the infrared sensor and the detection result of the sound sensor, and the sound source determined by the sound sensor. The rotation speed of the indoor blower is changed according to the type of. The rotation speed of the indoor blower is also changed in accordance with the combination of the movement amount of the occupant based on the infrared sensor and the type of the sound source based on the sound sensor. In addition, when it is determined that the type of the sound source is a conversation or broadcast receiving device group, the rotation speed of the indoor blower is lowered. In addition, when it is determined that the type of sound source is a heavy-weight apparatus group, the rotation speed of the indoor blower is increased. In addition, the above-mentioned method can be employ | adopted for discriminating a sound source.

By changing the rotation speed of the indoor blower according to the type of sound source, it is possible to reduce noise and improve comfort of the air conditioner itself in addition to energy saving operation. For example, when the sound source determined by the sound sensor is a conversation or a broadcast receiving device group, by lowering the number of revolutions of the indoor blower, the noise of the air conditioner itself is reduced, and the occupants are more likely to listen to the conversation or the broadcast. In this case, if the rotation speed of the indoor blower is frequently changed by the determination of the sound source, the noise of the air conditioner itself is changed, and the occupant is uncomfortable. Therefore, when the indoor blower rotation speed is changed, the predetermined period does not change the indoor blower rotation speed.

Further, it is possible to change the indoor blower rotation speed based on the combination of the movement amount of the occupant and the sound source. The infrared rays arriving from the room to the pyroelectric infrared sensor are sampled for a predetermined time at a predetermined sampling period, and the ratio Px of the number of times of detection of the infrared rays is calculated to be a sampling result. When this sampling result is less than a positive determination threshold, the division (detection division of a reaction) of the detection amount of reaction is divided into "reaction well". If the sampling result is equal to or greater than the positive determination threshold, the sampling result is compared with the strong determination threshold. When a sampling result is more than a strong determination threshold, the detection division of reaction is divided into "reaction steel." When the sampling result is less than the strong determination threshold, the detection division of the reaction is divided into "during reaction". When the response of the pyroelectric infrared sensor is "reaction tablet" or "reaction," and the sound source is summed up in the conversation or broadcast reception device group, the room is quietly watching the conversation or broadcast reception device. By lowering the frequency, it becomes easier for inmates to listen to conversations and broadcasts. By discriminating the sound source in the room in this way, the comfort of the occupants can be further improved.
