  When the air conditioner is in a heating operation, the vertical wind direction plate 291 is used in a substantially vertical posture as indicated by a dotted line in FIG. By doing in this way, the warm air which flows through the blowing air path 290 blows out downward from an air conditioner, reaches | attains near a floor surface, warms near a foot | foot, and makes the room a comfortable environment.

  Next, a method for reporting a failure state or an operation state when the air conditioner malfunctions or performs an unintended operation will be described with reference to FIGS. FIG. 7 is a display device light emission time chart 1 of the indoor unit. FIG. 8 is an air conditioner failure and operation code table, (a) is an indoor unit failure and operation code table, and (b) is an outdoor unit failure and operation code table. FIG. 9 is a sound emission time chart 1 of the indoor unit, (a) is a buzzer sounding time chart, and (b) is an LED light emission time chart. FIG. 10 is an indoor unit sound generator ringing time chart 1. FIG. 11 is an explanatory diagram of the names of each part of the time chart.

  An operation for reporting an abnormal or unintended operation during operation of the air conditioner will be described. Abnormality means that the air conditioner does not operate normally, such as overcurrent or overheating, and the unintended operation is an operation other than the operation intended by the user, although it is not abnormal.

  When an abnormal or unintended operation occurs during the operation of the air conditioner, the indoor unit control unit 10 generates and outputs a notification signal indicating the abnormal or unintended operation. Abnormal or unintended operation is detected by the indoor unit control unit 10 or the failure of the outdoor unit control unit and the program of the operation diagnosis unit. At this time, the indoor unit control unit 10 stops part or all of the functions of the air conditioner and causes a specific light emitting unit of the display device 397 to blink in accordance with the contents of an abnormal or unintended operation.

  Hereinafter, a case where an abnormal state occurs will be described as an example. For example, when the outdoor unit 6 is installed in a narrow place, the necessary space was secured to prevent the outdoor unit 6 from venting at the beginning of installation. If the outdoor unit 6 is not sufficiently ventilated by placing objects or potted plants on it, or if the plant grows and leaves grow, the high pressure side pressure of the refrigeration cycle will rise in the case of cooling, and the compressor of the refrigeration cycle will be excessive. Load is applied, and the compressor stops because it cannot maintain the rotation of the compressor.

  In this case, although the air conditioner continues the air blowing operation, the cooling function is stopped, and the failure diagnosis unit of the outdoor unit control unit comprehensively determines the short circuit and the open state of each circuit of the outdoor unit 6 to reduce the compressor overload lower limit. Diagnose and send the information to the indoor unit control unit 10. Based on this information, the indoor unit control unit 10 repeats lighting of the LED 397-3 for only the display device 397 for 0.35 seconds with the light of 0.35 seconds turned off as shown in FIG. Flashes repeatedly in cycle.

  The combination of the type of the blinking LED and the number of blinks and the failure state are coded in advance and summarized in the failure code table as shown in FIG. 8, and the failure code table is determined by the type of blinking LED and the number of blinks. It is possible to know the state of the failure by referring to it.

  At this time, the user of the air conditioner observes the indoor unit 2 and notices that the display device 397 is blinking because the air conditioner does not operate even when the operation is performed. A user who notices the flashing of the display device 397 often asks the store where the air conditioner was purchased or the service department of the manufacturer over the telephone how to resume operation.

  Upon receipt of the inquiry, the person in charge at the store or service department grasps the model of the air conditioner, the failure phenomenon, and the like according to the inquiry from the user. However, when the user calls, it is rare to remember exactly which LED blinks how many times, and the failure status notification from the user is “The air conditioner does not operate”, “ It is normal that it stays at about 2 points of “the LED of the air conditioner is flashing”.

  On the other hand, when asking which LED is blinking how many times, the user has to read the character written on the blinking LED, and must count and count the number of times. .

  However, asking this, it may impose an unpleasant burden on the user, such as whether the user's eyes are good, in the case of a foreigner, the ability to distinguish characters, and prohibiting blinking while counting. There are many cases where the user becomes angry and helps to get necessary information because of the frustration when the air conditioner cannot be used.

  For this reason, after dispatching a service person to the user's house and accurately grasping the failure information, if it is a simple repair, it can be repaired on the spot, but if it is not a simple repair, revisit However, since necessary parts, tools, and techniques are checked and a full repair is made, if it is not a simple repair, it will take longer.

  In the meantime, the user was forced to endure, and the service department had to visit the user's home only for accurately grasping the failure information, and there was a problem that the efficiency of the repair could not be improved.

  The air conditioner of the present invention is effective in such a case, and after the person in charge of the service department asks the model, failure phenomenon, etc. from the user, this air conditioner has a failure notification function by a buzzer sound. Like the sound of “beep” and the sound of “beep, beep, beep”, show the buzzer sound, teach the buzzer sound method and request the buzzer sound. .

  In the embodiment, as a method of sounding the buzzer, a method of pressing the internal operation button 55h ("up / down" button) of the remote controller 5 for 5 seconds or more is adopted, and when the buzzer 395 is sounding, the same up / down button 55h is pressed for 5 seconds or more. By pushing for a long time, the buzzer 395 is configured to stop ringing.

  Since the buzzer sounds only by pressing and holding a specific button on the remote control 5, even an unfamiliar user can easily operate it. When listening to the buzzer, the response sound that is heard every time the remote control 5 is operated is intermittent. As it rings, you can see it right away.

  Subsequently, the person in charge makes a telephone mouthpiece close to the air conditioner and requests, for example, a buzzer sound for one minute. If the telephone is a landline telephone, it may be difficult to bring the mouthpiece close to the air conditioner, but this request can be easily met in recent years when mobile phones are widespread.

  Since the frequency of the buzzer 395 is set to 0.3 kHz to 3.4 kHz, it can be transmitted by both a fixed telephone and a cellular phone. Since it is selected in a band apart from a male 0.8kHz and a female 1.2kHz, it is easy to distinguish from the voice of a person, and the person in charge of the service department can clearly hear the failure information generated by the air conditioner through the phone. it can.

  In the embodiment, transmission by telephone is possible, and the frequency of the sound of the buzzer 395 is set to 2 kHz in consideration of easy availability in the market.

  The ringing sound of the buzzer 395 is composed of a combination of a short pulse sound and a long pulse sound as shown in FIG. In the example of the description, there are two short “beep” sounds, a long pause time and the next long “beep” sound is “beep ...”. There are long pauses, followed by a long pause, followed by “Beep” and “Peep ...”. ,..., Beep,..., Beep,. At this time, only the display LED 397-3 of the display device 397 of the indoor unit 2 blinks in synchronization with a long pulse sound as shown in FIG. 9B.

  Here, the name and length of each part of the ringing sound will be described with reference to FIGS.

  One cycle of the notification sound is a notification sound cycle, which is 13.95 seconds in the example of the description, and the length varies depending on the failure state. In the embodiment, it is limited to 30 seconds at the longest.

  The ringing sound cycle is composed of a short pulse portion that is an intermittent of a short pulse, a long pulse portion that is an intermittent of a long pulse, and a silencer 1 and a silencer 2 that divide them.

  The short pulse portion is composed of a combination pulse composed of a plurality of short pulses sandwiching the short stop portion, and a combination stop portion is provided between the combination pulses. The combination of one set pulse and one set stop is called a set cycle, and the combination of one short pulse and one short stop is called a short pulse cycle.

  The short stop portion is set to 0.03 seconds or longer so that the short pulse can be recognized as “pip ...”, and in the embodiment, the short stop portion is set to 0.05 seconds. In addition, the group stop part has a length three times longer than that of the short stop part in order to prevent misinterpretation of the short pulse in the group pulse, and is set to 0.5 seconds in the embodiment.

  The silencers 1 and 2 are set to 3 seconds or longer, and 5 seconds in the embodiment. This is the time to write the number of short pulses in the short pulse part, the number of short pulses in the set pulse, and the number of long pulses in a note, etc. It is possible to grasp failure information.

  The long pulse part is composed of long pulses, and a long stop part is provided between the long pulses. The combination of one long pulse and one long stop is called a long pulse cycle. The long pulse portion is synchronized with the blinking of the display device 397 to make it easy to understand that the same failure content is being displayed and to prevent confusion. For this reason, the length of the long stop portion is set to 0.2 seconds or more so that the blinking of the display device 397 can be recognized even if it is influenced by the visual afterimage, and is set to 0.35 seconds in the embodiment.

  The person in charge in the telephone service department listens to the buzzer sound, counts the number of short pulses in the set pulse and the number of set pulses, and takes notes in the silencer 1. At this time, if the number of short pulses and the number of paired pulses are captured and memorized as a rhythm, the discrimination is successful. Next, the number of long pulses is counted and a note is taken by the silencer 2.

  Since it is requested that the buzzer sound be heard for 1 minute, it is possible to hear at least two cycles of ringing sound and accurately understand the coded failure information. The person in charge who accurately grasps the failure code (coded failure information) can know the failure state by comparing the failure code with a predetermined failure code table.

  The person in charge who has grasped the failure status tells the user whether the failure can be solved by the user or a failure that requires dispatch of a service person, confirms the intention of the user, and the user wishes to dispatch a service person. For example, check the parts, tools, technology, and materials according to the failure status, and arrange the dispatch of a service person with these.

  The person in charge of the service department, after grasping the failure state, informs the user of the operation to stop the buzzer sound so that the quiet environment in the room can be restored.

  A serviceman with appropriate parts, tools, technology, and materials that are sufficient and appropriate for the failure information visits the user's home, checks the LEDs 397-2 to 6 of the display device 397, and needs it. In response, inspect, repair and complete the interior of the air conditioner in more detail.

  As described above, since the failure information can be accurately grasped at the time of the first inquiry from the user, there is no waste of time to repair, and the repair can be completed efficiently and in a short period of time.

  Next, other failure cases will be described with reference to FIGS. FIG. 12 is a display device light emission time chart 2 of the indoor unit. FIG. 13 is a sound emission time chart 2 of the indoor unit, (a) is a buzzer sounding time chart, and (b) is an LED light emission time chart.

  In addition, as a next example, when the connection between the indoor unit 2 and the outdoor unit 6 is incompletely connected to the indoor terminal block of the connection cable, due to insufficient length, etc., contact between the connection cable and the terminal block The part has heat, and the contact resistance increases due to the progress of oxidation over time. Further, the temperature of the contact part rises, and the temperature fuse provided along the terminal block is melted. In this case, the air conditioner is stopped, and the failure diagnosis unit of the indoor unit control unit 10 comprehensively determines the short circuit and the open state of each part of the circuit, diagnoses that the terminal block temperature fuse of the indoor unit 2 is blown, and As shown in FIG. 12, the timer LED 397-2 is turned on and off for 0.35 seconds three times and repeatedly flashes in a cycle of resting (turning off) for 2 seconds.

  Since the air conditioner does not operate and the display device 397 blinks, the failure information is transmitted to the service department in the same process as described above.

  Similarly to the above, when the up / down button 55h of the remote controller 5 is pressed for 5 seconds or longer, the buzzer 395 sounds as shown in FIG. As shown in FIG. 13 (a), the buzzer 395 makes a short “beep” sound once, has a long pause, and the next long “beep” sound “beep”. "..., beep, ..., beep," followed by a long pause, followed by "beep" and "peep, ..., beep, ..."・, “Peep,” is repeated. At this time, the timer LED 397-2 of the display device 397 of the indoor unit 2 blinks in synchronization with a long pulse sound as shown in FIG. The person in charge of the service department can grasp the details of the failure at an early stage by identifying the ringing sound by telephone.

  With the intermittent buzzer and the blinking of the LED, the content of the failure can be known as “melting of the terminal block temperature fuse of the indoor unit 2” with reference to the failure code table of FIG.

  In this way, if the failure state is systematically divided, the failure part (major classification) is reported and the part of the failure is reported, and the details of the failure are reported by the small classification, the failure state can be easily subdivided and the failure Helps to understand the condition. In the embodiment, the failure part is classified by the number of short pulses in the set pulse of the buzzer 395 and the number of set pulses. For example, when a short intermittent sound called “beep” is once, If the beep sounds twice, it can be reported separately as an outdoor unit.

  Furthermore, the content of the failure is classified by the number of long intermittent sounds that say “beep,...”, For example, a short intermittent sound such as “beep” is a long time that says “beep” across the silencer. When the pulse sound is 3 times, the terminal block temperature fuse of the indoor unit 2 is blown, and the short intermittent sound “Pippi” is 2 times and the long pulse sound “Peep” is 5 times with the silencer sandwiched between Systematically categorizes like an overload lower limit cut of the outdoor unit 6.

  Similarly, regarding the blinking of the display device 397, the failure part is classified by the type of LED, and when the blinking is the timer LED 397-2, it can be reported separately as an indoor unit, and when the blinking LED 397-3, it is an outdoor unit. .

  Further, the contents of the failure are classified by the number of times the LED blinks. When the timer LED 397-2 blinks three times, the terminal block temperature fuse of the indoor unit 2 is blown, and when the Mimori LED 397-3 blinks five times, the outdoor unit. It can be reported as 6 overload lower limit cut.

  The case where the air conditioner has failed has been described above. However, even when the air conditioner performs an unintended operation, the operation state is indicated by blinking on the display device 397 as described above. Since this is an unintended operation, the user asks the manufacturer's service department or dealer.

  The person in charge of the service department that has received the inquiry requests the buzzer 395 to ring, as described above, and hears and identifies the operation information directly by ear. The person in charge grasps the operation state of the air conditioner from the operation information and the operation code table. The person in charge who understands the operating condition of the air conditioner explains the current operating condition of the air conditioner to the user and informs the user that the prohibited operation has not been accepted or that the operation can be continued with normal operation. be able to. As a result, the user's concerns are resolved, the understanding of the air conditioner is deepened, and if the same thing happens next, it can be dealt with correctly and no unnecessary calls are made. In addition, for the service department, it is not necessary to dispatch a service person to an air conditioner in a normal state at the user's home, and the service person can be appropriately operated.

  As described above, the air conditioner according to the embodiment includes the blinkable display device and the buzzer for remote control operation response, and the peak of the sound of the buzzer in the range of 0.02 to 20 kHz is 0.3 kHz to 3. At 4 kHz, the failure information or operation information is notified by blinking of the display device and intermittent sound of the buzzer.

  In general, the voice band frequency of a telephone is 0.3 kHz to 3.4 kHz, and a telephone call can be satisfactorily performed within this range.

  In addition, when a malfunction occurs in home appliances, or when the operation is normal but different from the user's intention (including when the user performs a prohibited operation), this can be reported to the user. Therefore, there is something that can report the failure status or operation status on the display unit, but the information is coded, and if it is not the person in charge of the manufacturer's service department or dealer, the information is accurately grasped This is difficult, and it is difficult for an unfamiliar user to accurately tell the flashing status of the display by telephone when requesting the service department to repair the fault or eliminate the unintended operation. It was necessary to visit the person's house and check the failure state or operation state directly. For this reason, normal operation is wasted, and even in the case of a failure, there are few things that can be repaired at the first visit except for a minor failure. Every day, the technology, parts, materials, etc. necessary for repair are arranged and visited again for repair.

  According to the air conditioner of the embodiment, when a failure or an unintended operation is performed, a buzzer can be sounded in addition to a blinking failure display or an operation display. Since the sound of the buzzer sound is within the voice band that can be transmitted by telephone, this sound can be transmitted to the service department of the manufacturer of the device through the telephone. Thereby, the person in the service department who is accustomed to the failure information or the operation information of the air conditioner can hear and grasp accurately.

  In this way, in addition to the failure or operation status heard from the user, the equipment service department can hear the results of the failure diagnosis or operation diagnosis of the air conditioner itself with its own ears. It is possible to know the failure state or the operation state accurately.

  As a result, it is possible to accurately grasp the failure condition or operating condition of the air conditioner at the time of the service request from the user. When visiting a home, the technology, parts, procedures, etc. necessary for the repair can be prepared in advance, and a quick repair is performed.

  For this reason, the response | compatibility to a service request becomes quick and can provide the air conditioner which becomes a profit of both a user and a manufacturer.

  In this case, the air conditioner is often equipped with an LED for displaying the operation status and a buzzer for confirming that the signal has been received by operating the remote control, without increasing the number of parts. Functions can be added and cost performance is good.

  In addition, since a buzzer sounds in synchronization with the blinking of the display, it is easy to recognize the relationship and does not confuse the user.

  In recent years, mobile phones have become widespread, so when sending notification sounds, hold the mobile phone over the air conditioner's notification section to hear the notification sound from a nearby location. There is no need.

  Furthermore, when you visit the user's home for repairs and receive failure information directly from the air conditioner, the failure information is reported by the buzzer, so take notes while listening to the notification sound. Can do. In the case of only blinking by a display as in the past, if it is attempted to count the number of blinks, it is necessary to take notes with the eyes facing the display, and it is uncertain whether the taken notes are accurate. However, if you look at the memo, you may miss the flashing, which is inconvenient.

  In the present invention, while listening to the notification sound with the ear, the eyes can see the memo firmly and take an accurate memo, so there is less possibility of mistaken pulse of the notification sound or an incorrect memo.

  Of course, the same effect can be obtained even if the blinking of the display device is replaced with lighting / dimming of the display device.

  In the air conditioner of the example, the peak in the range of 0.02 to 20 kHz of the sound of the buzzer is 1.8 kHz to 3.4 kHz.

  In general, the frequency of voice when people speak is said to be 0.1 kHz to 8 kHz for men, 0.15 kHz to 10 kHz for women, and the center band is said to be 0.8 kHz for men and 1.2 kHz for women. .

  According to the air conditioner of the example, the frequency of the notification sound is separated from the center band of the voice and close to the upper limit frequency side that can be transmitted by telephone, so it is easy to distinguish even if it overlaps with human speech, It can be clearly identified, and there are fewer re-listenings because it is difficult to hear or difficult to hear.

  For this reason, the air conditioner with a small burden of information transmission to the service department of the user can be provided.

  In addition, the air conditioner of the embodiment includes a short pulse portion in which the intermittent sound is composed of a pulse sound having a short intermittent interval, a long pulse portion composed of a pulse sound in which the intermittent interval is long, a short pulse portion, and a long pulse portion. It consists of a combination with a silencer that separates.

  This makes it possible to distinguish the failure classification or operation classification from the failure content or operation content with the length of the pulse sound that is easy to identify even on the telephone, so that the person in charge in the service department can easily identify and repeat the error to make it easy to identify and make it difficult to hear. Re-listening is reduced, failure information or operation information is smoothly transmitted, communication between the user and the service department is improved, and a good relationship is established.

  In addition, since a long silencer is provided between the short pulse part and the long pulse part, when the person in charge of the service department receives a call, the silencer after listening to the short pulse part has a set number of pulses and a short pulse. It is convenient that the number of sets of pulse parts is recorded, the number of the next long pulse is counted, and the number can be recorded in the subsequent silencer.

  For this reason, the air conditioner with a small burden of information transmission to the service department of the user can be provided.

  Moreover, the air conditioner of an Example reports failure classification or operation | movement classification by the said short pulse part, and reports failure content or operation | movement content by the said long pulse part.

  As a result, it is possible to detect a failure report or action report with a pulse sound with short intermittent intervals that is easy to hear, know the failure classification or operation classification with the rhythm, and know the contents of the failure or operation with the number of long pulse sounds with subsequent intermittent intervals. .

  In this way, by assigning failure classification or operation classification and failure content or operation content to two types of long and short pulse sounds, the number of failure or operation content that can be reported can be increased, and the details of failure or operation are detailed. It becomes possible to report in a subdivided manner, and it becomes possible to respond to the service appropriately and quickly, thereby reducing user dissatisfaction.

  For this reason, it is possible to provide an air conditioner that can appropriately report service by subdividing and reporting the failure state or operation state by failure classification or operation classification.

  Moreover, the air conditioner of an Example has the length of the said muffling part for 3 seconds or more.

  As a result, after confirming the number of long and short pulses, time is taken to make a note of the number of pulses, failure information or operation information can be recorded accurately, and the user can be burdened by repeatedly listening back and forth. Less.

  For this reason, it is possible to provide an air conditioner in which failure information or operation information is reported accurately and accurately and the burden on the user is low.

  Moreover, the air conditioner of an Example blinks the specific light emission part of the display apparatus according to the intermittent pattern of the intermittent sound of a short pulse part synchronizing with the intermittent sound of a long pulse part.

  As a result, the light emitting part is changed for each failure classification or operation classification indicated by the intermittent pattern of the notification sound of the short pulse part, and the flashing light is emitted, so even if the ambient noise is loud and the intermittent sound generator is not clearly audible When a service person visits the user's home and confirms failure information or operation information, the failure classification or operation classification and the failure content or operation content are determined by the position of the flashing light emitting part of the display device and the number of blinks. it can.

  On the other hand, even when the blinking of the display device cannot be seen well due to the installation position or illumination, the failure classification or operation classification and the failure content or operation content can be determined by the intermittent sound generation device. In this way, failure information or operation information is reported by both the sound generator and the display device, so failure information or operation information can be confirmed on either side, failure information or operation information cannot be confirmed, and the cause investigation This saves time and leads to faster repairs.

  For this reason, the air conditioner which can grasp | ascertain a failure state or an operation state appropriately can be provided using either one of a sound generator and a display apparatus.

  Further, in the air conditioner of the embodiment, the short pulse portion is composed of one or a plurality of sets of a plurality of short intermittent sound pulses, and the long pulse portion is a single or a plurality of long intermittent sound pulses. It consists of

  As a result, the short pulse part is composed of a set of pulses composed of a plurality of short pulse cycles, so it becomes an intermittent sound that is clearly different from the long pulse part, and systematically classifies failure states or operating states hierarchically. It is possible to intuitively detect whether the data is higher order or lower order data. In addition, when the person in charge of the service department who received the call explains the situation to the user and asks the user to transmit the notification sound from the air conditioner by telephone, “pip pip” is used to explain to the inexperienced person in words. The sound can be explained to the user as if it were a beeping sound, and the user can clearly recognize the difference in sound, making it easier to respond to requests from the service department and smoothly proceeding with repair activities. Convenient for both users and service departments. Furthermore, by changing the number of short pulse cycles in the set pulse, the types of faults or operations that can be reported and the number of faults or operations can be further increased. It becomes possible to respond to the service appropriately and quickly, and the dissatisfaction of the user is reduced.

  For this reason, it is possible to provide an air conditioner capable of further subdividing and reporting the failure state or the operation state into the failure classification or the operation classification and more appropriately handling the service.

  Further, in the air conditioner of the embodiment, the short pulse portion is composed of a set pulse including short pulses of 5 pulses or less with a short intermittent interval.

  In general, the intermittent pulse sound can be captured as part of the rhythm when the number is small. For example, the rhythm is “two short pulses”, “three short pulses”, “four short pulses”, “five short pulses”, and “five short pulses”. However, as the number increases, it sounds like a continuous monotonous sound, making it difficult to accurately count that number.

  Of course, depending on the person, even an intermittent short pulse of 6 or more can be regarded as a rhythm. However, as the number of pulses increases, such a person rapidly decreases. Generally, with a little training, short pulses of up to 5 positions can be identified as rhythms.

  According to the air conditioner of the embodiment, since it is a short pulse of 5 pulses or less, it can be easily captured as a rhythm, and there is no hesitation in identification.

  Therefore, it is possible to provide an air conditioner that accurately reports a failure classification or an operation classification with an intermittent sound of short pulses that can be identified by hearing.

  In this case, there may be a case where the LED of the display device is insufficient for failure classification by the buzzer.

  Moreover, the air conditioner of an Example sets the repetition space | interval of a report sound within 30 seconds.

  In general, when a person is awake, he cannot remain physiologically stationary, and moves a part of his body such as hands, legs and face consciously or unconsciously within a few minutes. For this reason, when calling the service department and reporting failure information with a notification sound, you must hold the mobile phone over the air conditioner for one cycle of the notification sound and wait for the notification to go silently. If the period of the notification sound is long, the body of the person holding the mobile phone will shake in the middle, the mobile phone will move away from the air conditioner, and the transmission sound to the person in charge in the service department receiving will be reduced In other words, it becomes impossible to hear or wait for the time to come, and the transmission of the notification sound must be stopped halfway, and it must be transmitted again from the beginning, which is a heavy burden on the user.

  According to the air conditioner of the embodiment, since the cycle of the notification sound is short, the transmission time is shortened, the burden on the user is lightened, and the failure information or the operation information is smoothly transmitted to the service department. Thus, the failure information or operation information of the service department is grasped at an early stage, and a quick response is possible.

  For this reason, a user's burden can be eased and the air conditioner which can receive a quick service can be provided.

  Moreover, the air conditioner of an Example can change the sound volume of a report sound in several steps.

  As a result, the strength of the notification sound can be adjusted according to the surrounding noise environment, and failure information or operation information can be transmitted even from a location where noise is high.

  Therefore, it is possible to provide an air conditioner that can reliably transmit failure information or operation information even from a noisy location.

  In addition, the air conditioner of the embodiment can be operated to stop and start the notification sound during failure notification or operation notification.

  Thereby, if necessary, it is possible to grasp the failure state or the operation state by instructing the user to notify the user of the failure information or the operation information with the notification sound and listening via the telephone. Moreover, after that, the notification sound can be stopped and the quietness can be restored in the room. At this time, the flashing of the synchronized display devices may be continued so that it is continuously displayed that a failure has occurred, repair is required, or an unintended operation is being performed.

  For this reason, it is possible to provide an air conditioner that can keep the room in a quiet environment even during failure display or operation display and can also check failure information or operation information with sound as necessary.

  Moreover, the air conditioner of an Example restrict | limits the duration of a report sound.

  As a result, even if the buzzer stop operation is not performed, the buzzer stops after a predetermined time, and the room becomes quiet even when the method of the stop operation is not known, at bedtime, or when you are absent. In addition to being able to cope calmly with the operation that is not performed, stopping the buzzer saves a little energy. At this time, as described above, the flashing of the synchronized display device is preferably continued. The user notices the flashing, calls the service department, listens to the person in charge of the service department, and reports the failure information or operation information of the air conditioner by operating the failure notification sound or the operation notification sound. Can be transmitted to the service department by sound and receive services.

  Therefore, it is possible to provide an air conditioner that returns quietness and saves energy while clarifying the display of failure or operation.

  In the air conditioner of the embodiment, the short stop length between the plurality of short pulses is 30 ms or more, and is 1/3 or less of the length of the set stop portion between the set pulses.

  In general, when a buzzer is pulsed and made to ring and the interval between pulses is gradually shortened, the intermittentness can be clearly distinguished at the beginning, but the intermittentness is gradually lost, and the applied pulse is intermittent. Even the ears can be heard as a continuous sound.

  This seems to be because the speed of the physical movement of the auditory transmission mechanism cannot keep up with the intermittent pulse, but the limit of the intermittent time is about 30 ms. When the time from when the pulse is turned off to when the next pulse is turned on becomes less than this, it is not heard as an intermittent sound, but as a continuous sound.

  According to the air conditioner of the embodiment, since the short stop portion length between pulses is set to 30 ms or more, a short pulse can be captured as an intermittent sound, and the length of the pair stop portion is 1/3 or less. Therefore, it is not confused with the stop time of the set pulse, and can be clearly distinguished.

  Therefore, it is possible to provide an air conditioner that can clearly hear short pulses in a set pulse and can subdivide failure classification or operation classification.

  In the embodiment, the failure classification or the operation classification is indicated by the short pulse, and the failure content or the operation content is indicated by the long pulse, but the role of the long and short pulse is reversed to indicate the failure classification or the operation classification by the long pulse. In this case, the same effect can be obtained even if the failure content or the operation content is indicated by a short pulse, but in this case, the blinking of the display device 397 synchronized with the buzzer sound is intermittent of the short pulse similar to the buzzer sound. Then, since the short stop portion is too short and an afterimage remains and the short pulse cannot be visually identified, it is preferable to blink the pulse having the length of the combined pulse.

  In addition, assignment of a failure classification to another LED of the display device 397 will be described with reference to FIG. FIG. 14 is an example of failure classification or operation classification.

  In the embodiment, only the display LED 397-3 and the timer LED 397-2 are described among the LEDs of the display device 397. However, a failure classification or an operation classification is assigned to other LEDs, for example, the cleaning LED 397-4 is a filter. Failure or unintentional operation of cleaning mechanism, clean LED 397-5 is failure or unintentional operation of air cleaning mechanism, sensor LED 397-6 is failure or unintentional operation of human detection mechanism, and operation LED 397-1 is in heating operation If the failure content or operation content is systematically classified so that the unintended operation is displayed, the failure content or operation content can be grasped more accurately.

  In accordance with this, when the short pulse part of the buzzer sounds as shown in FIG. 14 in the case of a failure or unintentional operation of the cleaning mechanism, three short pulses are used once for the failure or unintended operation of the air cleaning mechanism. In case of 3 short pulses 2 times, in case of failure of human detection mechanism or unintended operation, 3 short pulses 3 times, in case of unintentional operation during heating operation, 2 short pulses Configure and ring as 3 times.

  In the embodiment, the failure classification or the operation classification is classified according to the failure part or the operation part. However, the failure classification or the operation classification may be classified according to the failure phenomenon or the operation phenomenon, the failure function or the operation function, and the repair difficulty or repair Other classification methods, such as urgency and high repair costs, can also be used. In this way, the present invention can be applied to various devices depending on the form in which a failure or unintended operation occurs, and prompt repair or functional recovery can be desired.

  In the embodiment, the failure content or the operation content is grasped by the intermittent pattern of the buzzer 395. However, the failure content or the operation content may be reported by changing the tone, scale and strength of the buzzer sound. Needless to say, similar effects can be obtained.

  As described above, according to the air conditioner of the first aspect, in the air conditioner including the blinkable display device and the sound generating device that generates an intermittent sound in response to an operation from the remote controller. After the display device blinks due to failure information or operation information, an intermittent sound corresponding to the failure information or operation information generated from the sound generation device is reported in response to an operation from the remote controller.

  According to the air conditioner of claim 2, the peak of the intermittent sound of the sound generator in the range of 0.02 to 20 kHz is 0.3 kHz to 3.4 kHz.

  Accordingly, when a failure or an unintended operation is performed, a buzzer can be sounded in addition to a blinking failure display or operation display. Since the sound of the buzzer sound is within the voice band that can be transmitted by telephone, this sound can be transmitted to the service department of the manufacturer of the device through the telephone. Thereby, the person in the service department who is accustomed to the failure information or the operation information of the air conditioner can hear and grasp accurately.

  In this way, in addition to the failure or operation status heard from the user, the equipment service department can hear the results of the failure diagnosis or operation diagnosis of the air conditioner itself with its own ears. It is possible to know the failure state or the operation state accurately.

  As a result, it is possible to accurately grasp the failure condition or operating condition of the air conditioner at the time of the service request from the user. When visiting a home, the technology, parts, procedures, etc. necessary for the repair can be prepared in advance, and a quick repair is performed.

  For this reason, the response | compatibility to a service request becomes quick, and the air conditioner which becomes a profit of both a user and a manufacturer can be obtained.

  According to the air conditioner of claim 3, the peak of the intermittent sound of the sound generator in the range of 0.02 to 20 kHz is 1.8 kHz to 3.4 kHz.

  As a result, the frequency of the notification sound is separated from the center band of the voice and close to the upper limit frequency side that can be transmitted by telephone, so it is easy to distinguish even if it overlaps with human speech, and the notification sound can be clearly identified , Less re-listening to make mistakes and difficult to hear.

  For this reason, the air conditioner with a small burden of information transmission to the service department of the user can be obtained.

  According to the air conditioner of claim 4, the intermittent sound is a short pulse part composed of a pulse sound with a short intermittent interval, a long pulse part composed of a pulse sound with a long intermittent interval, and a short pulse. And a silencer that separates the long pulse part.

  This makes it possible to distinguish the failure classification or operation classification from the failure content or operation content with the length of the pulse sound that is easy to identify even on the telephone, so that the person in charge in the service department can easily identify and repeat the error to make it easy to identify and make it difficult to hear. Re-listening is reduced, failure information or operation information is smoothly transmitted, communication between the user and the service department is improved, and a good relationship is established.

  In addition, since a long silencer is provided between the short pulse part and the long pulse part, when the person in charge of the service department receives a call, the silencer after listening to the short pulse part has a set number of pulses and a short pulse. It is convenient that the number of sets of pulse parts is recorded, the number of the next long pulse is counted, and the number can be recorded in the subsequent silencer.

  For this reason, the air conditioner with a small burden of information transmission to the service department of the user can be obtained.

  According to the air conditioner of the fifth aspect, the failure classification or operation classification is reported in the short pulse portion, and the failure content or operation content is reported in the long pulse portion.

  As a result, it is possible to detect a failure report or action report with a pulse sound with short intermittent intervals that is easy to hear, know the failure classification or operation classification with the rhythm, and know the contents of the failure or operation with the number of long pulse sounds with subsequent intermittent intervals. .

  In this way, by assigning failure classification or operation classification and failure content or operation content to two types of long and short pulse sounds, the number of failure or operation content that can be reported can be increased, and the details of failure or operation are detailed. It becomes possible to report in a subdivided manner, and it becomes possible to respond to the service appropriately and quickly, thereby reducing user dissatisfaction.

  For this reason, it is possible to obtain an air conditioner capable of appropriately handling the service by subdividing and reporting the failure state or the operation state by the failure classification or the operation classification.

  Moreover, according to the air conditioner of Claim 6, the length of the said muffling part is 3 second or more.

  For this reason, it is possible to obtain an air conditioner in which failure information or operation information is reported accurately and accurately and the burden on the user is low.

  In addition, according to the air conditioner according to claim 7, in synchronization with the intermittent sound of the long pulse portion, the specific light emitting portion of the display device flashes according to the intermittent pattern of the intermittent sound of the short pulse portion. .

  As a result, the light emitting part is changed for each failure classification or operation classification indicated by the intermittent pattern of the notification sound of the short pulse part, and the flashing light is emitted, so even if the ambient noise is loud and the intermittent sound generator is not clearly audible When a service person visits the user's home and confirms failure information or operation information, the failure classification or operation classification and the failure content or operation content are determined by the position of the flashing light emitting part of the display device and the number of blinks. it can.

  On the other hand, even when the blinking of the display device cannot be seen well due to the installation position or illumination, the failure classification or operation classification and the failure content or operation content can be determined by the intermittent sound generation device. In this way, failure information or operation information is reported by both the sound generator and the display device, so failure information or operation information can be confirmed on either side, failure information or operation information cannot be confirmed, and the cause investigation This saves time and leads to faster repairs.

  For this reason, the air conditioner which can grasp | ascertain a failure state or an operating state appropriately can be obtained using any one of a sound generator and a display apparatus.

  Further, according to the air conditioner according to claim 8, the short pulse part is composed of one or a plurality of sets of a plurality of pulse sounds having a short intermittent interval, and the long pulse part is a single or a plurality of intermittent intervals. It is composed of long pulse sounds.

  As a result, the short pulse part is composed of a set of pulses composed of a plurality of short pulse cycles, so it becomes an intermittent sound that is clearly different from the long pulse part, and systematically classifies failure states or operating states hierarchically. It is possible to intuitively detect whether the data is higher order or lower order data. In addition, when the person in charge of the service department who received the call explains the situation to the user and asks the user to transmit the notification sound from the air conditioner by telephone, “pip pip” is used to explain to the inexperienced person in words. The sound can be explained to the user as if it were a beeping sound, and the user can clearly recognize the difference in sound, making it easier to respond to requests from the service department and smoothly proceeding with repair activities. Convenient for both users and service departments. Furthermore, by changing the number of short pulse cycles in the set pulse, the types of faults or operations that can be reported and the number of faults or operations can be further increased. It becomes possible to respond to the service appropriately and quickly, and the dissatisfaction of the user is reduced.

  For this reason, it is possible to obtain an air conditioner capable of further subdividing and reporting the failure state or the operation state into the failure classification or the operation classification and more appropriately handling the service.

  According to the air conditioner of the ninth aspect, the short pulse portion is composed of a set pulse composed of short pulses of 5 pulses or less with a short intermittent interval.

  Thereby, since it is a short pulse of 5 pulses or less, it can be easily captured as a rhythm, and there is no problem in identification.

  For this reason, the air conditioner which reports a failure classification or an operation | movement classification correctly by the intermittent sound of the short pulse which can be identified by hearing can be obtained.

  Moreover, according to the air conditioner of Claim 10, the repetition interval of a report sound shall be less than 30 second.

  As a result, since the repetition cycle of the notification sound is short, the transmission time is shortened, the burden on the user is lightened, the failure information or the operation information is smoothly transmitted to the service department, and the failure information of the service department is obtained. Or grasping | ascertainment of operation information is performed at an early stage, and a quick response is attained.

  For this reason, a user's burden can be eased and the air conditioner which can receive a quick service can be obtained.

  Moreover, according to the air conditioner of the eleventh aspect, the volume of the notification sound can be changed in a plurality of stages.

  As a result, the strength of the notification sound can be adjusted according to the surrounding noise environment, and failure information or operation information can be transmitted even from a location where noise is high.

  For this reason, the air conditioner which can transmit failure information or operation information reliably from a noisy place can be obtained.

  According to the air conditioner of the twelfth aspect, the notification sound can be stopped and started during the notification of the failure information or the operation information.

  Thereby, if necessary, it is possible to grasp the failure state or the operation state by instructing the user to notify the user of the failure information or the operation information with the notification sound and listening via the telephone. Moreover, after that, the notification sound can be stopped and the quietness can be restored in the room. At this time, the flashing of the synchronized display devices may be continued so that it is continuously displayed that a failure has occurred, repair is required, or an unintended operation is being performed.

  Therefore, it is possible to obtain an air conditioner that can keep the room in a quiet environment even during failure display or operation display and can also check failure information or operation information with sound as necessary.

  Moreover, according to the air conditioner of the thirteenth aspect, the duration of the notification sound is limited.

  As a result, even if the buzzer stop operation is not performed, the buzzer stops after a predetermined time, and the room becomes quiet even when the method of the stop operation is not known, at bedtime, or when you are absent. In addition to being able to cope calmly with the operation that is not performed, stopping the buzzer saves a little energy. At this time, as described above, the flashing of the synchronized display device is preferably continued. The user notices the flashing, calls the service department, listens to the person in charge of the service department, and reports the failure information or operation information of the air conditioner by operating the failure notification sound or the operation notification sound. Can be transmitted to the service department by sound and receive services.

  For this reason, it is possible to obtain an air conditioner in which quietness is restored and energy saving is achieved while the display of failure or operation is clear.

  According to the air conditioner of the fourteenth aspect, the length of the short stop portion between the plurality of short pulses is 30 ms or more and is 1/3 or less of the length of the pair stop portion between the set pulses.

  As a result, the length of the short stop portion between the pulses is set to 30 ms or more, so that the short pulse can be captured as an intermittent sound, and since the length of the pair stop portion is 1/3 or less, It is not confused with stop time and can be clearly distinguished.

  Therefore, it is possible to obtain an air conditioner that can clearly hear short pulses in a set pulse and can subdivide failure classification or operation classification.
