Description

  The present invention relates to an air conditioner having an utterance function for producing voice.

  In an air conditioner having an utterance function, when a situation that should be notified to the user, such as the occurrence of an abnormality, occurs, notification by voice or buzzer is performed. However, if a sound is emitted from the air conditioner while the user is sleeping, the user's sleep is prevented. Patent Document 1 describes that the brightness around the air conditioner is detected, and that the air conditioner does not sound when dark. In addition, it is described that the air conditioner does not sound even when driving at night.

JP 2001-317764 A

  However, when an emergency situation occurs at night, such as a malfunction of the air conditioner, if the air conditioner does not speak, the user will not notice the abnormality of the air conditioner and will not be able to take appropriate measures. .

  In view of the above, an object of the present invention is to provide an air conditioner that can convey the minimum necessary information to a user even when the user's activity is not active, such as during sleep.

  The air conditioner of the present invention includes an utterance unit that issues a message according to the operation of the air conditioner, a detection unit that detects human activity, and a control unit that controls the utterance unit based on the human activity, The control unit limits the utterance when the human activity is reduced.

  Human activity decreases due to sleep and reading. At this time, since the utterance is limited, the minimum information can be transmitted to the user without disturbing the user's sleep or reading.

  The detection unit monitors the time, and the control unit limits the utterance at a specific time. If the specific time is set to night, the specific time is the time during sleep when the user's activity is low. The time for the user to read or study may be set to a specific time. Therefore, when the detection unit detects that the person is sleeping, the control unit limits the utterance. The detection unit detects the brightness of the room, and when the room is dark, the control unit determines that the person is sleeping. When the room is bright, the control unit determines that a person is active.

  The control unit restricts the utterance according to the importance level of the message, and the utterance unit utters the message changed according to the restriction of the utterance. The lower the importance of the message, the more severe the restriction of the utterance. When the importance of the message is low, the utterance part emits the message by shortening the message or lowering the volume. It can be a short message or a low volume message, but it is sufficient to convey the minimum amount of information. Also, when the importance of the message is high, the restriction on the utterance is relaxed to ensure that necessary information is conveyed to the user.

  When the importance of the message is low, the utterance unit does not utter the message at a specific time. Messages with low importance are not urgent and can be left without utterance. This avoids disturbing the user who is sleeping or reading.

  When the importance of the message is high, the control unit determines whether the message can be changed, and when the message can be changed, the utterance unit issues the changed message. Even an important message can be issued so as not to disturb the user.

  A speech unit that issues a message according to the operation of the air conditioner, and a control unit that performs a timer operation based on the set operation content, and the control unit sets the timer operation after setting the timer operation The utterance unit is operated to issue a message to inform the user.

  The user may forget that he has set timer operation. Therefore, the user can reconfirm the set timer operation by issuing a message after a certain amount of time has elapsed after setting.

  When the operation is stopped by the user's instruction before the timer operation is started, the control unit operates the speech unit so as to issue a message related to the set timer operation. Before the timer operation is started, the user can reconfirm the set operation content.

  When the set timer operation is being performed, if the control unit determines that the human activity is decreasing, the control unit operates the speech unit to issue a message to stop the operation. That is, after the timer operation is started, when there is no user operation for a certain period of time, or when the state where the user is not in the room continues for a certain period of time, the control unit determines that the human activity is reduced. The control unit stops the operation after issuing the message. A state in which there is no person in the room can be regarded as a state in which human activity has decreased. At this time, even if a message is issued, nothing is operated. Therefore, by stopping driving, useless driving can be eliminated.

  According to the present invention, when the user's activity is not active, such as during sleep, by restricting the utterance, the necessary minimum information can be transmitted to the user while reducing the user's discomfort.

The air conditioner includes a temperature detector 11 that detects the room temperature and the outside air temperature, an illuminance detector 12 that detects the brightness of the room, and a human body detector 13 that detects the presence or absence of a person in the room. An illuminance detector 12 and a human body detector 13 are provided on the front surface of the indoor unit. The illuminance detector 12 is an illuminance sensor using a photodiode, a phototransistor, or the like. The human body detector 13 uses an infrared sensor. As the human body detector 13, a camera-type sensor such as a CCD or a CMOS may be used. Further, the infrared sensor and the camera may be combined. The human body detector 13 can detect not only a person who is stationary due to sleep or the like but also that a person has moved.

  The air conditioner has a remote controller 20 that can communicate with the control unit 10. The indoor unit is provided with a wireless communication unit 21 that communicates with the remote controller 20. The wireless communication unit 21 performs bidirectional wireless communication using infrared rays, Bluetooth (registered trademark), ZigBee (registered trademark), or the like. Thereby, the control unit 10 can communicate with the remote controller 20 through the communication unit 21. Moreover, as shown in FIG. 4, the air conditioner can communicate with a communication terminal 22 such as an external smart phone, a tablet terminal, a mobile phone, or a notebook PC via a network. The air conditioner includes a communication unit 23 that communicates with the communication terminal 22. The communication unit 23 performs communication using a LAN such as a wireless LAN, and is connected to the Internet via a router 24 and a modem 25. The control unit 10 communicates with the communication terminal 22 and the server 26 through the Internet.

  The user operates the remote controller 20 or the communication terminal 22 to give an instruction to the air conditioner. The control unit 10 includes a CPU, a ROM, and a RAM, and the control unit 10 controls the refrigeration cycle so as to execute an air conditioning operation according to an instruction from the remote controller 20 or the communication terminal 22. For example, a user in the room operates the remote controller 20 to select a set temperature and any operation such as a heating operation, a cooling operation, a dehumidifying operation, and an automatic operation. The remote controller 20 transmits a control signal based on a user operation to the indoor unit. When the control unit 10 receives the control signal from the wireless communication unit 21, the control unit 10 turns on the compressor 27, the expansion device 28, and the blower fan 29 based on the set temperature in the instructed air conditioning operation and the detected room temperature and outside air temperature. Control.

  Moreover, the control part 10 performs a timer driving | operation based on the driving | operation content set by the user. The user operates the remote controller 20 or the communication terminal 22 to set the timer operation. As operation contents in the timer operation, an operation start time, an operation end time, a type of air conditioning operation, a wind speed, a wind direction, and the like are set. As operation contents in the on-timer operation, an operation start time, a type of air conditioning operation, a wind speed, a wind direction, and the like are set. The operation end time is set as the operation content in the off timer operation, and the type of air conditioning operation, the wind speed, the wind direction, and the like are set as necessary.

  The indoor unit is provided with a display unit 30 for notifying various kinds of information and an utterance unit 31 for generating sound. The display unit 30 includes a lamp such as an LED and a display. The lamp and display of the display unit 30 are provided on the front panel 4, and a display window 32 is formed below the open panel 7. When the control unit 10 controls the display unit 30, the lamp is turned on or blinks, and characters and the like are displayed on the display. Even if the open panel 7 is closed, the display on the display unit 30 can be confirmed through the display window 32. The user can obtain information such as the driving situation by looking at the lighting state of the LED.

  The utterance unit 31 includes a speaker 33 that emits sound, and a sound generation unit 34 that generates a sound output signal based on a command from the control unit 10 and outputs the sound output signal to the speaker 33. The speaker 33 is attached near the air outlet 3 of the front panel 4. Specifically, the speaker 33 is attached near the upper portion of the air outlet 3. The front surface of the speaker 33 is exposed on the front surface of the front panel 4. When the open panel 6 is closed, the speaker 33 cannot be seen from the outside, but the sound of the speaker 33 comes out of the gap between the front panel 4 and the open panel 6, so that the user can hear the sound of the speaker 33.

  When the remote controller 20 is operated, a control signal is transmitted to the indoor unit. When receiving the control signal, the control unit 10 identifies the content of the instruction from the control signal and controls the uttering unit 31 so that a message corresponding to the operation of the remote controller 20 is issued. That is, the control unit 10 outputs a sound signal corresponding to the content of the instruction to the sound generation unit 32. The uttering unit 31 utters a message formed based on the voice signal.

  When power is supplied to the air conditioner, the control unit 10 monitors the condition of the air conditioner and surrounding conditions such as indoors and outdoors based on outputs of various detectors, switches, timers, and the like. . When these situations change, the control unit 10 operates the uttering unit 31 to issue a message corresponding to the situation. Examples of changes in the situation include instructions from the remote controller 20 or the communication terminal 22 by the user's operation, start / stop / change of operation, occurrence of an abnormality in the air conditioner, time for maintenance such as cleaning of the filter, indoor / outdoor conditions, etc. Appropriate driving advice according to the situation.

  A message is also issued at the communication terminal 22. That is, the control unit 10 transmits a message to the communication terminal 22. The communication terminal 22 has a speaker and issues a received message from the speaker.

  Here, the illuminance detector 12 and the human body detector 13 are detection units that detect human activity. When a person is sleeping, the room is dark. When a person is reading or studying, the room is bright, but there is no movement. In this situation, human activity is declining. Also, when there are no people in the room, there is no human activity.

  The control unit 10 determines human activity based on the outputs of the illuminance detector 12 and the human body detector 13. The control unit 10 operates the utterance unit 31 so as to issue a message in accordance with a person's activity. That is, the control unit 10 restricts utterances by the utterance unit 31 when it is determined that the human activity is decreasing. When it is determined that a person is active, speech is not restricted.

  By restricting the utterance, the message to be uttered is changed. As the message change, either or both of shortening of the message and volume reduction at the time of speaking are performed. Therefore, when it is detected that the human activity is decreasing, the control unit 10 changes the message and operates the uttering unit 31 to issue the restricted message. The utterance unit 31 utters a shortened message or lowers the volume.

  Here, four patterns are used as the restriction patterns. The control unit 10 selects one pattern according to the message to be issued. The message of pattern 1 is a message that is not changed at all. The message of pattern 2 is a message that is not shortened but the volume is lowered. The message of pattern 3 is a message shortened with the volume kept unchanged. The message of pattern 4 is a message that is shortened and the volume is lowered.

  The time when people go to bed is almost every day. Therefore, the user inputs a time for which the speech is desired to be limited. The control unit 10 sets the input time as a specific time. The specific time is, for example, 22:00 to 6 o'clock. The control unit 10 determines that the human activity is decreasing at a specific time. As shown in FIG. 5, when any situation changes, the control unit 10 instructs the utterance unit 31 to utter. At this time, the control unit 10 checks the current time (S1). When the current time is between 22:00 and 6 o'clock, the control unit 10 does not operate the speech unit 31 (S2). No message is issued. When an abnormality occurs in the air conditioner, the control unit 10 automatically stops the operation. When the current time is other than 22:00 to 6 o'clock, the control unit 10 operates the speech unit 31 (S3). The utterance unit 31 utters the message as it is. The user who heard the message takes action according to the message.

  Even when a message is issued when the user is sleeping, the user is likely not to notice the utterance. In this way, it is possible to prevent the user's sleep from being disturbed by not speaking at a specific time that can be regarded as sleeping.

  Note that it may be directly detected whether or not the user is sleeping. The human body detector 13 detects the movement of a person. That is, it is determined that the person is sleeping when there is no movement of the person for a predetermined time despite the presence of the person in the room. When the control unit 10 detects that the user is sleeping, the control unit 10 limits the utterance.

  The specific time is not limited to night, and may be set to an arbitrary time. For example, the time for the user to read or study is set as the specific time. No message is issued at a specific time set. Therefore, the user can concentrate on reading or studying.

  When the specific time is not set, the speech is restricted based on the brightness of the room. When the air conditioner or the surrounding situation changes and the need for speech occurs, the control unit 10 instructs the speech unit 31 to speak. As shown in FIG. 6, the control unit 10 determines the brightness of the room based on the output of the illuminance detector 12 (S5). When the output of the illuminance detector 12 is smaller than a predetermined value that is predetermined according to the room to be detected, the room is determined to be dark, and when the output is equal to or higher than the predetermined value, the room is determined to be bright.

  When the room is bright, the control unit 10 determines that the user is active, selects the pattern 1 and operates the uttering unit 31. The utterance unit 31 utters the message as it is (S6). When the room is dark, the control unit 10 determines that the user's activity is decreasing and restricts the utterance. First, the control unit 10 determines whether the message to be issued can be shortened (S7). The criterion for determining whether or not a message can be shortened is that a long message can be shortened, and a short message cannot be shortened. A long message consists of a plurality of sentences, and a short message consists of one sentence.

  Next, the control unit 10 determines whether the volume of the message to be issued can be changed (S8). When the volume change is permitted, the change is allowed. When the volume change is not allowed, the change is impossible. Depending on the message, the volume is determined in advance, and the volume cannot be changed in the case of an important message that requires urgent, and the volume can be changed in the case of a message without urgency such as advice.

  When the message cannot be shortened and the volume cannot be changed, the control unit 10 selects the pattern 1. The utterance unit 31 issues a message as it is (S9). In this case, since the issued message is short, there is a possibility that the user's sleep or reading may be hindered, but necessary information is transmitted to the user. When the message cannot be shortened and the volume can be changed, the control unit 10 selects the pattern 2 and decreases the volume of the message (S10). For example, when the original volume is high or medium, the volume is reduced. When the original volume is low, the volume is kept as it is. The uttering unit 31 lowers the volume and issues a message (S11). In this case, necessary information can be conveyed to the user without disturbing the user's sleep or reading.

  When the message can be shortened, the control unit 10 changes the message to be issued to the shortened message (S12). As an example of an abbreviated message, “Check that the filter and dust box are installed correctly. If the problem cannot be resolved, check“ Kana malfunction ”in the instruction manual. ", The shortened message is" Cleaning error. " An abbreviated message for each message is created in advance, a message and a list of the abbreviated messages are stored in a message table, and the message table is saved in memory. The control unit 10 refers to the message table when shortening the message.

  The control unit 10 determines whether the volume of the message to be issued can be changed (S13). When the volume cannot be changed, the control unit 10 selects the pattern 3. The utterance unit 31 utters a shortened message that does not change the volume (S14). In this case, the minimum necessary information can be transmitted to the user in a short time, and the user's sleep and reading are not hindered. When the volume can be changed, the control unit 10 selects the pattern 4 and lowers the volume of the message (S15). The utterance unit 31 utters a shortened message at a low volume (S16). In this case, the minimum necessary information can be conveyed to the user without disturbing the user's sleep or reading.

(Second Embodiment)
By the way, some messages have urgency depending on what they convey. Therefore, the importance is attached to the message according to the content of the message. For example, the importance of a message that is issued in an emergency situation such as a failure of an air conditioner is high. On the other hand, the importance of messages that inform users of useful information is low. When the activity of the person is decreasing, the control unit 10 limits the utterance according to the importance of the message to be issued. Other configurations are the same as those of the first embodiment.

  When messages are of low importance, utterance restrictions are tightened. When the importance of the message is high, the restriction on utterance is relaxed. When the importance level of the message is divided into three levels of high, medium and low, the control unit 10 determines whether the message can be shortened and whether the volume of the message can be reduced when the importance level is high. If the message can be shortened or the volume can be reduced, the message is changed. When the importance level is medium, the control unit 10 restricts at least one of message shortening and volume reduction. When the importance level is low, the control unit 10 performs message shortening and volume reduction limitation. That is, when the importance level is low, the control unit 10 changes the message by restricting at least one of shortening the message and decreasing the volume.

  The importance is set in advance for each message, a list of messages describing the importance is stored in the message table, and the message table is stored in the memory. In the message table, a shortened message and whether or not the volume of the message can be changed are registered. When restricting the utterance, the control unit 10 refers to the message table and changes the message.

  When the situation of the air conditioner or the surrounding situation changes, the control unit 10 instructs the utterance unit 31 to utter. As shown in FIG. 7, the control unit 10 checks the current time (S20). When the current time is a specific time, for example, between 22:00 and 6 o'clock, the control unit 10 checks the importance of the message to be issued (S21). When the importance is low (medium or less), the control unit 10 does not operate the utterance unit 31 (S22). No message is issued.

  When the importance level is high, the control unit 10 determines whether the message to be issued can be shortened (S23). When the message cannot be shortened, the control unit 10 determines whether the volume of the message to be issued can be changed (S24). When the volume cannot be changed, the control unit 10 selects the pattern 1. The utterance unit 31 issues a message as it is (S25). For example, a message such as “Could not operate normally” is issued without being changed.

  When the volume can be changed, the control unit 10 selects the pattern 2 and decreases the volume of the message (S26). The uttering unit 31 utters a message that has not been shortened by lowering the volume (S27).

  When the message can be shortened, the control unit 10 changes the message to be issued to the shortened message (S28). For example, there is a shortened message such as “Cleaning error”. And the control part 10 judges whether the volume of the message to emit can be changed (S29). When the volume cannot be changed, the control unit 10 selects the pattern 3. The utterance unit 31 issues a shortened message without changing the volume (S30). When the volume can be changed, the control unit 10 selects the pattern 4 and decreases the volume of the shortened message (S31). The utterance unit 31 decreases the volume and issues a shortened message (S32).

  When the current time is other than 22:00 to 6 o'clock, the control unit 10 determines whether the room is bright or dark (S33). When the room is bright, the control unit 10 determines that the user is active, selects the pattern 1 and operates the uttering unit 31. The utterance unit 31 utters the message as it is (S34).

  When the room is dark, the control unit 10 checks the importance of the message to be issued (S35). When the importance is high, the control unit 10 determines whether the message to be issued can be shortened (S36). When the message cannot be shortened, the control unit 10 determines whether the volume of the message to be issued can be changed (S37). When the volume cannot be changed, the control unit 10 selects the pattern 1. The utterance unit 31 issues a message as it is (S38).

  When the volume can be changed, the control unit 10 selects the pattern 2 and decreases the volume of the message (S39). The uttering unit 31 utters a message that has not been shortened at a reduced volume (S40).

  When the message can be shortened, the control unit 10 changes the message to be issued to the shortened message (S41). And the control part 10 judges whether the volume of the message to emit can be changed (S42). When the volume cannot be changed, the control unit 10 selects the pattern 3. The utterance unit 31 issues a shortened message without changing the volume (S43). When the volume can be changed, the control unit 10 selects the pattern 4 and decreases the volume of the shortened message (S44). The utterance unit 31 decreases the volume and issues a shortened message (S45).

  When the importance level is low, the control unit 10 checks the level of the importance level of the message to be issued (S46). When the importance level is medium, the control unit 10 changes the volume of the message (S47). And the control part 10 judges whether the message to emit can be shortened (S48). When the message cannot be shortened, the control unit 10 selects the pattern 2. The uttering unit 31 utters a message that has not been shortened at a reduced volume (S49). When the message can be shortened, the control unit 10 selects the pattern 4 and changes the message to be issued to the shortened message (S50). The utterance unit 31 decreases the volume and issues a shortened message (S51).

  When the importance is low, the control unit 10 selects the pattern 4, changes the message to be issued to a shortened message (S52), and lowers the volume of the shortened message (S53). The utterance unit 31 lowers the volume and issues a shortened message (S54).

  If the message to be issued is short, the message cannot be shortened. Therefore, instead of issuing a message by voice, a short sound such as a buzzer or a melody may be emitted. In addition, a notification message shorter than the message may be issued. As a result, the user can be notified that there is a message.

  As described above, the lower the importance of the message, the stricter the restriction of the utterance. Further, even a highly important message can be issued so as not to disturb the user as much as possible. Therefore, the minimum necessary information can be transmitted to the user without disturbing the user who is sleeping or reading.

(Third embodiment)
The air conditioner performs a timer operation for controlling the air conditioning operation according to the set time. Timer operation includes simple on-timer operation that starts air-conditioning operation after the set time elapses, easy-off timer operation that stops air-conditioning operation after the set time elapses, and on-off that starts air-conditioning operation at any set time. There are a timer operation, a timer operation for stopping the air-conditioning operation at a set arbitrary time, a timer operation for performing the air-conditioning operation on a set day of the week or time, and the like.

  The user operates the remote controller 20 to set the timer operation. Patent document (Japanese Patent Laid-Open No. 8-35717) describes that a message such as “Timer set” is issued when the user sets timer operation with the remote controller 20.

  After the user performs the setting operation, the timer operation is executed after a lapse of time. The user may forget that he has set the timer operation. Therefore, when the timer operation is performed, it becomes suspicious. Further, if the user forgets that the timer operation is started and goes out, the air-conditioning operation is performed without being attended. As a result, power is wasted. Therefore, in view of the above, an object of the present embodiment is to provide an air conditioner that can notify a user that timer operation is set.

  After setting the timer operation, the control unit 10 that performs the timer operation based on the set operation details operates the uttering unit 31 to issue a message to notify that the timer operation is set. Other configurations are the same as those of the first embodiment and the second embodiment.

  The timing for issuing the message is immediately after the user sets the timer operation and when a certain time has elapsed after the timer operation is set. In addition, after the timer operation is set, the air conditioning operation is performed regardless of the timer operation. The control unit 10 operates the uttering unit 31 so as to issue a message regarding timer operation at such timing.

  As shown in FIG. 8, the user operates the remote controller 20 to set the timer operation. When receiving the signal from the remote controller 20, the control unit 10 sets the timer operation based on the set operation content (S60). When the timer operation is set, a message corresponding to the set content is issued. That is, the control unit 10 confirms the content of the timer operation (S61), and operates the speech unit 31 so as to issue a message of the set operation content. When the timer operation is the on-timer operation, the utterance unit 31 issues a message of the set time and operation content (S62). For example, a message such as “7 am am reserved for heating at 25 ° C.” is issued. When the timer operation is the off timer operation, the utterance unit 31 issues a message for the set time (S63). For example, a message such as “Stop driving at 11:00 pm” is issued.

  Thus, by issuing a message when setting the timer operation, the user can confirm the set operation content. Therefore, if the setting is wrong and the operation content is not intended, the operation content can be changed or canceled.

  If the user performs an operation when the air conditioning operation is performed before the set timer operation is started, a message regarding the set timer operation is issued. As shown in FIG. 9, when the air-conditioning operation is stopped by the user's operation (S65), the control unit 10 confirms the presence or absence of the set timer operation (S66). When the on-timer operation is reserved, the control unit 10 operates the speech unit 31 so as to issue a message regarding the operation content of the timer operation being reserved. The utterance unit 31 issues a message about the operation content of the timer operation (S67). For example, a message such as “I am reserving driving at 25 ° C. from 7 am tomorrow, Monday, Sunday” is issued. When the on-timer operation is not set, the control unit 10 does not operate the speech unit 31. The utterance unit 31 does not utter any message (S68).

  Thus, when the user gives an instruction to stop the operation, it is notified that the on-timer operation is reserved. Therefore, even if the user forgets that the timer operation has been reserved, the reservation can be reconfirmed. Here, when the timer operation is no longer necessary, the reservation can be canceled and useless operation can be prevented.

  The user may forget that he has set timer operation. When the set time is reached, the air conditioning operation is started. At this time, if the user is away from the room due to going out or the like, the air conditioning operation is performed in an unattended state. In order to prevent such a situation, when it is confirmed that there is no person in the room, a message is issued and the air conditioning operation is stopped.

  As shown in FIG. 10, when the set time is reached, the on-timer operation is started (S70). The control unit 10 monitors the presence of a person in the room (S71). The presence / absence of a person is determined based on the output of the human body detector 13 or based on the presence / absence of operation of the remote controller 20.

  When no person is detected or when there is no operation signal from the remote controller, the control unit 10 determines that there is no person and checks whether or not a person is present for a certain period of time (S72). When the absence of a person continues for a certain time, the control unit 10 operates the uttering unit 31 so as to issue an unattended operation warning message, and increases the utterance count by one. The utterance unit 31 issues a warning message indicating that unmanned driving is being performed (S73). The control unit 10 checks whether the utterance count has reached a certain number (S74). When the utterance count has not reached the predetermined number, the control unit 10 continues to monitor (S71).

  When the room is unattended and the utterance count reaches a certain number, the control unit 10 determines that the room is unattended. And the control part 10 operates the speech part 31 so that the message of an air-conditioning driving | operation stop may be issued. The utterance unit 31 issues an automatic stop message (S75). After the utterance, the control unit 10 stops the air conditioning operation (S76).

  When the person is detected by the human body detector 13 or when an operation signal is received from the remote controller 20, the control unit 10 determines that the person is in the room and continues monitoring as it is (S71). At this time, the control unit 10 sets the utterance count to 0 (S77).

  Thus, when the user forgets to set the timer operation and goes away, a warning is issued. When the user notices a warning, unnecessary operation can be eliminated by the user performing an appropriate operation such as operation stop. In addition, when the user is away due to going out or the like, the air conditioning operation is automatically stopped, so that unnecessary operation can be avoided and power consumption can be suppressed.

  Further, even when the user is in the room during the timer operation, the activity is reduced if the user is sleeping. When such a decrease in activity is detected, a warning message may be issued and the air conditioning operation may be stopped. Thereby, the stop time of the timer operation is advanced, and the power consumption can be reduced by shortening the operation time.

  As described above, the air conditioner of the present invention controls the utterance unit 31 based on the human activity, the utterance unit 31 that issues a message according to the operation of the air conditioner, the detection unit that detects the human activity. The control unit 10 includes a control unit 10, and the control unit 10 restricts utterances when human activity is reduced. Necessary minimum information can be conveyed while suppressing utterances when the user is sleeping or reading.

  The detection unit monitors the time, and the control unit 10 limits the utterance when the specific time comes. It is possible to limit the utterance in the time when the activity is reduced arbitrarily set by the user.

  When the detection unit detects that a person is sleeping, the control unit 10 limits the utterance. A sleeping user can be prevented from being disturbed by speech.

  The detection unit detects the brightness of the room, and when the room is dark, the control unit 10 limits the utterance. Speaking can be restricted when the room is dark when it can be considered that human activity is declining.

  The control unit 10 restricts the utterance according to the importance level of the message, and the utterance unit 31 utters the message changed according to the restriction of the utterance. By restricting the utterance according to the importance of the message, necessary information can be surely transmitted.

  The lower the importance of the message, the more severe the restriction of the utterance. When the importance of the message is low, the utterance unit 31 utters the message by shortening the message or lowers the volume. For messages of low importance, the minimum necessary information can be conveyed.

  When the importance of the message is low, the utterance unit 31 does not utter a message at a specific time. The user can be prevented from being disturbed while sleeping or reading.

  When the importance of the message is high, the control unit 10 determines whether the message can be changed. When the message can be changed, the utterance unit 31 issues the changed message. Even if the message has a high importance level, by restricting it as much as possible, it is possible to suppress utterances while conveying necessary information to the user.

  The air conditioner of the present invention includes an utterance unit 31 that issues a message according to the operation of the air conditioner, and a control unit 10 that performs a timer operation based on the set operation content. After the setting, the speech unit 31 is operated so as to issue a message in order to notify that the timer operation is set. When the user forgets that the timer operation is set, the timer operation can be noticed.

  When the operation is stopped by the user's instruction before the timer operation is started, the control unit 10 operates the speech unit 31 so as to issue a message related to the set timer operation. The user can reconfirm the timer operation.

  When the set timer operation is being performed, if the control unit 10 determines that the human activity is decreasing, the control unit 10 operates the speech unit 31 to issue a message to stop the operation. By issuing a message, it is possible to call attention when unnecessary driving is performed.

  After the timer operation is started, when there is no user operation for a certain period of time, or when a state in which the user is not in the room continues for a certain period of time, the control unit 10 determines that human activity is decreasing. It can be confirmed that the user is not in the room by going out.

  The control unit 10 stops the operation after issuing the message. Useless driving when the user is not indoors can be eliminated.

  In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added within the scope of the present invention. In each embodiment, when there is no person in the room, a message may be notified from the communication terminal 22. Set the user to send messages externally. When this setting is made, the control unit 10 instructs the communication terminal 22 to notify the message. The communication unit 23 transmits message data to the communication terminal 23. Upon receiving the message data, the communication terminal 23 utters the message by voice or displays the message on the display. The user can recognize a message from the air conditioner even when outdoors. If necessary, it is possible for the user to cope with the remote operation.
