Description

  The present invention relates to an air conditioner.

  The air conditioner includes an electric motor such as a compressor, an indoor fan, and an outdoor fan. For example, when a disaster such as an earthquake occurs and a leak or short circuit occurs in these devices, there is a risk of electric shock or fire. Therefore, an air conditioning system has been proposed in which when a disaster information such as earthquake bulletin is received, an actuator such as a compressor is stopped to suppress a secondary disaster (see, for example, JP 2011-202832 A). Thereby, an air conditioning system can be stopped before a disaster occurs, and the accident of an air conditioning system can be suppressed.

JP 2011-202832 A

  However, in the air conditioning system disclosed in Japanese Patent Application Laid-Open No. 2011-202832, it is possible to start the operation of the air conditioning system regardless of whether there is an abnormality after the air conditioning system is stopped due to a disaster. A secondary disaster may occur. Further, in the air conditioning system, it is possible to prevent the occurrence of a secondary disaster by not operating the air conditioning system at the user's judgment. However, if the air conditioning system is not operated, the room cannot be kept comfortable. .

  Then, this invention aims at providing the air conditioner which can suppress the secondary damage by the driving | operation of the air conditioner which can maintain the interior of a living room at comfortable temperature, and abnormality has generate | occur | produced by the disaster. .

  In order to achieve the above object, the air conditioner of the present invention outputs a notification sound to a heat pump that exchanges heat between the living room and the outside of the room, a communication unit that communicates with the outside, and the living room. A notification sound output unit, a control unit, and a power supply unit that supplies power to at least the heat pump, the communication unit, the notification sound output unit, and the control unit, the control unit via the communication unit When the disaster information is received, after the disaster information is output as a notification sound from the notification sound output unit, the power supply from the power supply unit to other than the control unit is stopped, and after a predetermined time has elapsed since the reception of the disaster report , An initial diagnosis for confirming the energized state from the power supply unit, and a driving diagnosis for confirming an abnormality during driving by operating the heat pump continuously for a predetermined time when no abnormality is confirmed in the initial diagnosis And Serial control unit, when an abnormality is confirmed in the early diagnosis or driving time of diagnosis, stops the supply of power to other than the control unit by the power supply unit.

  According to this configuration, since the notification of the disaster information is notified by voice using the notification speaker, the occurrence of the disaster (possibility of occurrence) can be quickly transmitted to the person in the room. In addition, when the air conditioner receives disaster information (here, the earthquake early warning is received), the power supply is temporarily stopped and the air conditioner enters a stopped state. Then, after the earthquake or the like is settled, the presence or absence of abnormality of the air conditioner and the abnormal part when there is an abnormality are specified. And when there is an abnormality, the operation is not performed. Thereby, it is possible to suppress the occurrence of secondary disasters such as electric shock due to electric leakage and fire due to short circuit.

  In the above-described air conditioner, the air conditioner further includes a temperature detection unit that detects a temperature in the room, and when the heat pump is in a non-operating state when the disaster information is received, the control unit is abnormal in the initial diagnosis. If the temperature is not confirmed, the heat pump may be operated in an appropriate operating state on the basis of the temperature in the room detected by the temperature detector, and the driving diagnosis may be performed.

  According to this configuration, since the operation of the heat pump is determined so that the amount of heat exchanged outside and inside the room increases, a temperature difference in the refrigerant pipe is likely to occur, and the temperature difference is likely to increase. Thereby, at the time of drive diagnosis, it is easy to detect the abnormality of the heat pump due to temperature.

  In the above-described air conditioner, the control unit stores an operation state of the heat pump when the disaster information is received, and the disaster information is received by the heat pump when no abnormality is confirmed in the initial diagnosis. It is also possible to perform driving diagnosis by operating in the current operating state.

  According to this structure, in order to make a living room comfortable, it is made to operate | move on the conditions equivalent to the heat pump which was performing heat exchange. Since the operation of the heat pump is determined, a temperature difference of the refrigerant pipe is likely to occur, and the temperature difference is likely to increase. Thereby, at the time of drive diagnosis, it is easy to detect the abnormality of the heat pump due to temperature.

  In the above configuration, after determining that there is no abnormality in the driving diagnosis, the control unit may put the heat pump into an operation state when the disaster information is received.

  According to this structure, the time which has stopped the air conditioner can be shortened. Thereby, it can suppress that the comfort of a living room falls.

  The said structure WHEREIN: The said control part may notify a diagnostic result to an external apparatus using the said communication part after completion | finish of the said initial stage diagnosis or the said driving time diagnosis.

  In the above configuration, the external device may be a server that is connected via the Internet and accumulates abnormality information.

  In the above-described configuration, the apparatus further includes a remote controller that is arranged in the living room and performs operation input, and the control unit is performing the initial diagnosis at least until a predetermined time elapses after receiving the disaster notification. After the abnormality is confirmed, the operation input from the remote controller may not be accepted.

  According to this configuration, the air conditioner does not operate even if the remote control is mistakenly operated while the diagnosis of the air conditioner is not completed or when there is an abnormality in the air conditioner. Therefore, although there is an abnormality, the operation is started, and it is possible to suppress an electric shock due to electric leakage, ignition due to a short circuit, or the like.

 According to the present invention, it is possible to provide an air conditioner that can maintain a comfortable temperature in a living room and can suppress secondary damage caused by the operation of an air conditioner in which an abnormality has occurred due to a disaster.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a schematic view of a living room equipped with an air conditioner according to the present invention. As shown in FIG. 1, the air conditioner A includes an indoor unit IM installed inside the living room Rm and an outdoor unit OM installed outside the living room Rm. As shown in FIG. 1, the living room Rm is a space surrounded by the ceiling CL, the floor FL, and the four walls BW. An indoor unit IM is attached to one of the walls BW. In the actual living room Rm, there are cases where the walls BW, ceiling CL, etc. are provided with openings such as doors, windows, etc., but these openings are closed when air conditioning is performed, and the walls BW, ceiling CL, etc. Since it may be considered as one, it is omitted. The air conditioner A performs air conditioning (cooling, heating, air purification) in the room Rm by taking the air in the room Rm into the indoor unit IM and discharging the conditioned air.

  Next, the detail of the air conditioner A concerning this invention is demonstrated with reference to drawings. FIG. 2 is a block diagram showing a schematic configuration of the air conditioner according to the present invention, and FIG. 3 is a schematic diagram of a heat pump of the air conditioner shown in FIG.

  As shown in FIG. 2, the air conditioner A includes a control unit 1, a heat pump 2, a storage unit 3, a notification speaker 4 (notification sound output unit), a communication unit 5, a remote control communication unit 6 (remote controller communication unit), and a remote controller. 7 (remote controller) and a power supply unit 8.

  The control unit 1 controls the operation of each unit constituting the air conditioner A. The control unit 1 includes, for example, a processing circuit such as a CPU. The control unit 1 is disposed in the indoor unit IM. The control unit 1 changes the air conditioning conditions such as temperature, humidity, air volume, and wind direction, and the air in the room Rm is harmonized. In addition to these, control processing of each part of the air conditioner A is performed. A room temperature sensor S1 is connected to the controller 1. The room temperature sensor S1 is a sensor that measures the temperature inside the room Rm. The room temperature sensor S1 measures the temperature in the room Rm periodically or in response to control from the control unit 1, and sends the information to the control unit 1.

  As shown in FIGS. 2 and 3, the heat pump 2 includes a compressor 21, a four-way valve 22, an outdoor heat exchanger 23, a decompression unit 24, an indoor heat exchanger 25, an outdoor fan 26 and an indoor fan 27. The compressor 21, the four-way valve 22, the outdoor heat exchanger 23, the decompression unit 24, and the indoor heat exchanger 25 are connected by a refrigerant pipe, and a refrigerant circuit in which a refrigerant is sealed is configured.

  The decompression unit 24, the indoor heat exchanger 25, and the indoor fan 27 are arranged in the indoor unit IM. The compressor 21, the four-way valve 22, the outdoor heat exchanger 23, and the outdoor fan 26 are arranged in the outdoor unit OM. The compressor 21, the four-way valve 22, the outdoor fan 26 and the indoor fan 27 are connected to the control unit 1. The decompression unit 24 may be provided not in the indoor unit but in the outdoor unit OM.

  The compressor 21 is a device that compresses the refrigerant, and the conditions (temperature, humidity) of the air conditioning can be changed by controlling the operation (for example, the number of revolutions) of the compressor 21. The four-way valve 22 changes the flow direction of the refrigerant circuit. By switching the direction in which the refrigerant flows in the four-way valve 22, the heat pump 2 switches to a cooling operation for cooling the living room or a heating operation for heating the living room. The decompression unit 24 reduces the pressure of the refrigerant. For example, a capillary tube or an expansion valve is employed.

  The outdoor heat exchanger 23 and the indoor heat exchanger 25 are for exchanging heat between the air inside and outside the living room Rm and the refrigerant, for example, fins for increasing the cross-sectional area of the refrigerant pipe Can be mentioned. It is possible to increase the efficiency of heat exchange by blowing air to the fins and forcibly sending air. Therefore, in the heat pump 2, an outdoor fan 26 is provided in the vicinity of the outdoor heat exchanger 23, and an indoor fan 27 is provided in the vicinity of the indoor heat exchanger 25.

 In addition, the heat pump 2 is provided with a temperature measuring unit 28 for measuring the temperature of a pipe (refrigerant pipe) through which the refrigerant flows. The temperature measurement unit 28 is connected to the control unit 1 and transmits the measured temperature of the refrigerant pipe to the control unit 1. For example, the temperature measurement unit 28 measures the temperature of the pipe connected to the discharge side of the compressor 21 and measures the temperature of the return pipe to the compressor 21. When the refrigerant is compressed by the compressor 21, the pressure increases and the temperature is high. On the other hand, the refrigerant that exchanges heat with the outdoor heat exchanger 23 and the indoor heat exchanger 25 and returns to the compressor 21 has a lower temperature than the discharge side. That is, in the heat pump 2, during the operation of the compressor 21, a temperature difference is generated between the discharge side pipe and the return pipe. And when this temperature difference has not arisen, it can be judged that abnormality of the heat pump 2, for example, the possibility that the refrigerant has leaked is high. In the air conditioner A according to the present embodiment, the temperature measuring unit 28 measures the temperatures of the discharge side pipe and the return pipe of the compressor 21, but is not limited thereto. You may measure the temperature of piping from which temperature changes compared with the time of a normal driving | operation when a refrigerant | coolant leaks.

  The storage unit 3 stores information and programs necessary when the control unit 1 performs various processes. The storage unit 3 includes a ROM (Read Only Memory) that can only read information, a RAM (Random Access Memory) that can access (read and write) information at any time, and the like.

  The remote control communication unit 6 and the remote control 7 perform wireless communication. In the air conditioner A, the remote controller communication unit 6 and the remote controller 7 perform communication using infrared rays. The remote control communication unit 6 receives the infrared signal from the remote control 7 and transmits the signal to the control unit 1. The remote controller 7 operates the air conditioner A from a remote location. The remote controller 7 includes a display unit 71 and an operation unit 72. The display unit 71 displays various information. Examples of information displayed on the display unit 71 include the current time and the operating state (cooling, heating, air blowing, dry, etc.).

  Further, when the remote control communication unit 6 and the remote control 7 are capable of two-way communication, information transmitted from the remote control communication unit 6 such as the temperature inside and outside the room, the continuous operation time of the air conditioner A, the filter maintenance instruction, etc. It is also possible to display information. In the air conditioner A of the present embodiment, the remote control communication unit 6 and the remote control 7 are capable of bidirectional communication. The operation unit 72 includes, for example, an input device such as a hard key. The operation unit 72 may include a touch input device that detects that an operation image displayed on the display unit 71 is touched and outputs an operation signal corresponding to the operation image, a so-called touch panel.

  Moreover, although the infrared communication using infrared light is employ | adopted for the communication with the remote control communication part 6 and the remote control 7, it is not limited to this. For example, a radio wave having a specific frequency may be used. A device that can perform communication between the remote control communication unit 6 and the remote control 7 with high accuracy can be widely used.

  The communication unit 5 is connected to a wireless and / or wired network. For example, the communication unit 5 is connected to a small-scale communication network built in a building including the living room Rm. Note that the small-scale communication network is constructed by at least one of wired and wireless. It may be a network connectable by both. For example, a terminal such as a smartphone or a tablet PC, a home security system, a home energy management system (HEMS), or the like is connected to the small-scale communication network. The air conditioner A can notify the information from the communication unit 5 to the above-described terminal or system or vice versa.

  The small communication network is connected to an external network such as the Internet or a telephone line. Thereby, the communication part 5 can transmit / receive information between the apparatuses connected to the external network via the small-scale communication network. The communication unit 5 may be directly connected to an external communication network such as the Internet or a telephone line (in FIG. 2, it is simply displayed as a communication network). At this time, the communication unit 5 may or may not be connected to the small-scale communication network. In the air conditioner A according to this embodiment, disaster information (for example, earthquake early warning) is notified from a disaster information notification server (not shown) provided on the Internet. Details of the disaster information and the notification of the disaster information will be described later.

  The communication unit 5 is connected to the control unit 1. When the communication unit 5 receives the disaster information, the communication unit 5 transmits the content of the received disaster information to the control unit 1. Note that the communication unit 5 does not receive disaster information regardless of whether the air conditioner A is performing air conditioning (hereinafter referred to as an operating state) or not performing air conditioning (hereinafter referred to as a stopped state). Receive. Further, when the communication unit 5 receives the disaster information, the control unit 1 may return from the standby state, and the control unit 1 may also be always ON as with the communication unit 5. . In the air conditioner A of the present embodiment, the control unit 1 is in a standby state when in a stopped state, and returns from the standby state when the communication unit 5 receives disaster information.

  The notification speaker 4 is a notification sound output unit that outputs a notification sound from the air conditioner A. As the notification sound, for example, a sound such as an alarm sound, disaster information received by the communication unit 5, information on the temperature, humidity, etc. of the room Rm can be cited. Further, the current time and the current operation status (cooling, heating, continuous operation time, etc.) may be included. The notification speaker 4 is connected to the control unit 1 and outputs a notification sound in accordance with an instruction from the control unit 1. The notification sound output unit may include a notification speaker 4 and a notification sound generation circuit that generates a notification sound output from the notification speaker.

  The power supply unit 8 supplies the electricity supplied from the commercial power system to each part of the air conditioner A with an appropriate voltage and / or current. The electricity supply source is not limited to the commercial power system, and may be a power source such as a storage battery or a generator.

  The power supply unit 8 includes an AC / DC converter, a DC / DC converter, and the like. Further, the power supply unit 8 adjusts the output of the compressor 21, the outdoor fan 26, and the indoor fan 27 by adjusting the electric current supplied to the compressor 21, the outdoor fan 26, and the indoor fan 27. The power supply unit 8 supplies operation electricity to the control unit 1, the storage unit 3, the notification speaker 4, the communication unit 5, and the remote control communication unit 6. The voltage and current supplied to the control unit 1, the storage unit 3, the notification speaker 4, the communication unit 5, and the remote control communication unit 6 are constant. The power supply unit 8 adjusts the electricity supplied to each unit based on instructions from the control unit 1. In addition, the control part 1 may be provided with backup power supplies, such as a storage battery, separately from the electric power supply part 8, so that electricity can be supplied even if supply of electricity is stopped at the time of a power failure or the like. The air conditioner A according to the present invention has the configuration described above.

  Next, disaster notification will be described. For example, an earthquake includes a P wave and an S wave having a slower propagation speed than the P wave. In a normal earthquake, after the P wave arrives from the epicenter and the initial tremor occurs, the S wave arrives, and the main shock with a larger amplitude than the initial tremor occurs. In Japan, an emergency earthquake warning (disaster notification) is transmitted immediately after the initial tremor is observed. When the room Rm is located away from the epicenter, there will be a delay time between the receipt of the earthquake early warning and the occurrence of the mainshock.

  In addition, the electrical wiring of the air conditioner A (for example, the electrical wiring that connects the indoor unit IM and the outdoor unit OM) may be damaged or the heat pump 2 may be abnormal due to an earthquake. Therefore, the air conditioner A according to the present embodiment is in a stopped state after receiving the disaster notification (here, the earthquake early warning). Thereafter, the air conditioner A diagnoses each part before restarting the operation.

  Below, the detail of operation | movement of the air conditioner concerning this embodiment is demonstrated with reference to drawings. FIG. 4 is a flowchart showing a diagnostic operation when receiving a disaster notification of the air conditioner according to the first embodiment.

  The communication unit 5 is in a state where the air conditioner A can receive the disaster information regardless of the operating state or the stopped state, and waits for the reception of the disaster information as shown in FIG. 4 (step S101). In the present embodiment, the earthquake early warning is received as disaster information, but the present invention is not limited to this. As described above, there are cases of tornado warnings, lightning warnings, etc., and other types of information. You may make it receive widely the information regarding the disaster which may generate | occur | produce the failure and damage of the air conditioner A. FIG.

  When the communication unit 5 receives the disaster information (Yes in step S101), the control unit 1 outputs a notification sound in the room Rm with the notification speaker 4 (step S102). Here, the notification sound includes an alarm sound such as a siren and an audio alarm.

  The control unit 1 confirms whether or not the air conditioner A is in operation (step S103). That is, when the disaster information is received, it is confirmed whether or not the air conditioner A is in the air conditioning of the living room Rm. When the air conditioner A is in operation (in the case of Yes in step S103), the control unit 1 issues an instruction to the power supply unit 8 to stop the power supply to other than the control unit 1, that is, the air conditioning The machine A is brought into a stopped state (step S104). In addition, when the control part 1 is provided with the backup power supply, the control part 1 may perform control which stops the electric power supply part 8 itself.

  When the air conditioner A is not in operation (No in step S103) or after the air conditioner A is stopped (after step S104), the control unit 1 waits until a predetermined time elapses. (Step S105). Here, the predetermined time is a time that is assumed from the time of receiving the earthquake early warning to the end of the mainshock (that is, until the arrival of the S wave is completed). The predetermined time may be a predetermined time (for example, 10 minutes), or may be determined by calculating from the location information of the epicenter and the current location. In this embodiment, it is set as a predetermined time. The predetermined time may be changeable by the user.

  When the earthquake early warning is received and a predetermined time has elapsed (Yes in step S105), the control unit 1 determines that the main shock has ended and diagnoses the presence or absence of an abnormality in each part of the air conditioner A ( Step S106). In addition, after receiving disaster information, let the diagnosis of the air conditioner A which stopped be an initial diagnosis.

  Here, the initial diagnosis will be described with reference to the drawings. FIG. 5 is a flowchart showing the operation of the initial diagnosis. The initial diagnosis shown in FIG. 5 diagnoses whether the air conditioner A has an abnormality that hinders operation due to a disaster (earthquake). In the air conditioner A, the compressor 21 and the outdoor fan 26 arranged in the outdoor unit OM are driven according to a control signal from the control unit 1 arranged in the indoor unit IM. Therefore, if communication between the indoor unit IM and the outdoor unit OM is not ensured, it is difficult to drive the compressor 21 and the outdoor fan 26 accurately. Therefore, in the air conditioner A, first, the communication state between the indoor unit IM and the outdoor unit OM is confirmed (step S201).

  The control unit 1 determines whether there is an abnormality in the communication state between the indoor unit IM and the outdoor unit OM from the result of confirming the communication state between the indoor unit IM and the outdoor unit OM (step S202). When there is an abnormality in the communication state between the indoor unit IM and the outdoor unit OM (Yes in step S202), the control unit 1 records that there is an abnormality in the communication state in the storage unit 3 (step S203). Then, it is determined that there is an abnormality (step S217), and the initial diagnosis is terminated (proceeds to step S107 in FIG. 4). That is, when there is an abnormality in the communication state between the indoor unit IM and the outdoor unit OM, the control unit 1 disposed in the indoor unit IM cannot transmit a control signal to the device disposed in the outdoor unit OM. Since the control unit 1 cannot accurately control the devices arranged in the outdoor unit OM, the initial diagnosis ends without performing other diagnosis.

  When there is no abnormality in communication between the indoor unit IM and the outdoor unit OM (No in step S202), the control unit 1 supplies power from the power supply unit 8 provided in the indoor unit IM to the outdoor unit OM. Is confirmed (step S204). Note that the supply of power from the power supply unit 8 to the outdoor unit OM is for confirming a short circuit or disconnection of the power wiring, and is performed in a short time. In addition, when checking the power supply in preparation for a case where the power wiring from the power supply unit 8 to the outdoor unit OM is short-circuited or disconnected, when the compressor 21 or the outdoor fan 26 is driven. It can be performed with a voltage and current smaller than the voltage and current. The confirmation of energization to each part of the heat pump 2 serves not only to check the state of each part but also to confirm the continuity of the electrical wiring from the power supply unit 8 to each part of the heat pump 2.

  And the control part 1 confirms whether there was abnormality in the electric power supply from the electric power supply part 8 to the outdoor unit OM from the confirmation result of the electric power supply from the electric power supply part 8 to the outdoor unit OM (step S205). If the power wiring from the power supply unit 8 to the outdoor unit OM is disconnected, it may cause an electric shock due to electric leakage or fire if it is short-circuited. Therefore, when it is determined that there is an abnormality in the power supply from the power supply unit 8 to the outdoor unit OM (Yes in step S205), the control unit 1 records in the storage unit 3 that there is an abnormality in the power supply. (Step S206), it is determined that there is an abnormality (step S217), and the initial diagnosis is terminated (proceeds to step S107 in FIG. 4).

  When there is no abnormality in the power supply from the power supply unit 8 to the outdoor unit OM (No in step S205), the control unit 1 checks the energized state of the four-way valve 22 (step S207). The control part 1 records the result of the determination which confirmed the energization state of the four-way valve 22 as the result 1 in the memory | storage part 3 (step S208). In addition, the diagnosis of the energization state of each part of the heat pump 2 is performed regardless of whether there is an abnormality. Therefore, the result 1 stored in step S208 includes information on the presence / absence of occurrence of an abnormality (electric leakage, short circuit, etc.) during energization. The same applies to the results 2 to 4 that appear below.

  Next, the control unit 1 confirms the energized state of the outdoor fan 26 (step S209). The control part 1 records the result of the determination which confirmed the energization state of the outdoor fan 26 as the result 2 in the memory | storage part 3 (step S210). Next, the controller 1 confirms the energization state of the compressor 21 (step S211). The control part 1 records the result of the determination which confirmed the electricity supply state of the compressor 21 as the result 3 in the memory | storage part 3 (step S212). Finally, the control unit 1 confirms the energization state of the indoor fan 27 (step S213). The control part 1 records the result of the determination which confirmed the energization state of the indoor fan 27 as the result 4 in the memory | storage part 3 (step S214).

  In addition, the energization confirmation of each part of the heat pump 2 is performed in the above-mentioned order. This order is an order in which, if possible, each part of the heat pump 2 is not easily damaged and damage is not easily caused to people around. However, the order of energization confirmation is not limited to this order.

  And the control part 1 confirms the results 1-result 4 which are the result of the energization confirmation of each part of the heat pump 2, and confirms whether at least any one has abnormality determination (step S215). If at least one of the results 1 to 4 is determined to be abnormal (Yes in step S215), the control unit 1 determines that there is an abnormality (step S217) and ends the initial diagnosis (FIG. 4). Go to step S107). If there is no abnormality determination in results 1 to 4 (No in step S215), control unit 1 determines that there is no abnormality (step S216) and ends the initial diagnosis (in step S107 of FIG. 4). move on).

  Returning to FIG. 4, the description of the operation of the air conditioner A is continued. As described above, after completing the initial diagnosis (after step S106), the control unit 1 checks whether or not there is an abnormality in the air conditioner A in the initial diagnosis (step S107). If there is an abnormality in the air conditioner A in the initial diagnosis (Yes in step S107), the control unit 1 displays the diagnosis result on the display unit 71 of the remote controller 7 (step S108). Then, the diagnosis ends. Examples of the display on the display unit 71 of the remote controller 7 include a point where the air conditioner A is abnormal and cannot be used, a location where the abnormality has occurred, a type of abnormality (for example, an error number), and the like. However, it is not limited to this. The diagnosis result is as stored in the storage unit. That is, communication abnormality between the indoor unit IM and the outdoor unit OM, power supply abnormality, and energization abnormality of each part diagnosed by the initial diagnosis. In addition to this, when a diagnosis is made, the diagnosis result is displayed. In addition, as a method of notifying the diagnosis result, a method of displaying the diagnosis result on the display unit 71 of the remote controller 7 is adopted, but the present invention is not limited to this. For example, notification is performed by voice using the notification speaker 4. May be.

  For example, the diagnosis result may be displayed even when there is no abnormality, and in this case, a character or an image that can recognize that there is no abnormality is displayed. The controller 1 notifies the person in the room Rm that the air conditioner A cannot be used by displaying an abnormality on the display unit 71 of the remote controller 7. And since the drive of the air conditioner A in which the abnormality has occurred is suppressed by checking the abnormality displayed on the display unit 71, secondary disasters such as electric shock due to electric leakage or ignition due to a short circuit are suppressed. be able to.

  As described above, it is confirmed by the initial diagnosis that no problem occurs even when power is supplied to the air conditioner A, mainly the heat pump 2. On the other hand, due to a disaster such as an earthquake, the refrigerant may be difficult to leak or circulate due to breakage of the refrigerant piping or the like. In such a case, diagnosis by operating the heat pump 2 for a certain period (hereinafter referred to as driving diagnosis) is required. Therefore, when there is no abnormality in the initial diagnosis (No in step S107), the control unit 1 puts the heat pump 2 into an operating state and puts the air conditioner A into an operating state (step S109). The heat pump 2 can perform a cooling operation or a heating operation, and is preliminarily determined in the present embodiment.

  The control unit 1 stands by until a predetermined time has elapsed from the start of the operation of the heat pump 2 (step S110). When the predetermined time has elapsed (Yes in step S110), the control unit 1 performs a driving diagnosis. Hereinafter, the driving diagnosis will be described with reference to a new drawing. FIG. 6 is a flowchart showing the operation during driving diagnosis.

  As shown in FIG. 6, the controller 1 first measures the temperature of the refrigerant pipe of the heat pump 2 by the temperature detector 28 and acquires the measurement result (step S301). By driving the heat pump 2, the temperature of the refrigerant pipe varies depending on the location. As described above, operating the heat pump 2 causes a temperature difference between the discharge-side piping and the return piping of the compressor 21. When this temperature difference does not occur or the temperature difference is small, it can be determined that the refrigerant filled in the heat pump 2 is leaking. Further, in some cases, the leakage of the refrigerant can be determined by measuring the temperature of the piping other than the discharge side piping and the return piping of the compressor 21. Therefore, the temperature of the refrigerant pipe is measured, and from the result, the control unit 1 confirms whether or not the heat pump 2 has an abnormality (step S302).

  When there is an abnormality in the heat pump 2 due to the temperature of the refrigerant pipe (Yes in step S302), the control unit 1 determines that the refrigerant is leaking from the refrigerant pipe, and records the refrigerant leak in the storage unit 3 (step S303). ). And the control part 1 judges that there exists abnormality in the air conditioner A (step S309), and complete | finishes a driving diagnosis (it progresses to step S112 of FIG. 4).

  When there is no abnormality in the heat pump 2 from the temperature of the refrigerant pipe (No in step S302), the control unit 1 measures the temperature in the room Rm with the room temperature sensor S1 (step S304). The control unit 1 calculates a temperature difference ΔT that is a difference between the measured temperature in the room Rm and the set temperature of the air conditioner A (step S305). In the air conditioner A, the heat pump 2 is operated so that the temperature in the room Rm becomes the set temperature. In a normal operation state, the temperature in the room Rm approaches the set temperature. From this, the control unit 1 compares the temperature difference ΔT with the threshold value Tth, and confirms whether or not the temperature difference ΔT is equal to or greater than the threshold value Tth (step S306).

  When the temperature difference ΔT is equal to or larger than the threshold value Tth (Yes in step S306), the control unit 1 determines that there is an abnormality in the temperature control of the air conditioner A, and records the temperature control abnormality information in the storage unit 3. (Step 307). And the control part 1 judges that there exists abnormality in the air conditioner A (step S309), and complete | finishes a driving diagnosis (it progresses to step S112 of FIG. 4). If the temperature difference ΔT is less than the threshold Tth (No in step S306), it is determined that the air conditioner A is operating normally, that is, there is no abnormality (step S308), and the driving diagnosis is terminated. (Proceed to step S112 in FIG. 4). In this embodiment, the diagnosis based on the temperature of the refrigerant pipe and the diagnosis based on the temperature in the room Rm are used as the diagnosis at the time of driving. However, the present invention is not limited to this. The diagnosis of abnormality that is not determined only by energization of the air conditioner A, that is, determined by driving, may be performed widely.

  Returning to FIG. 4, the description of the operation of the air conditioner A is continued. As described above, after ending the driving diagnosis (after step S1111), the control unit 1 checks whether or not there is an abnormality in the air conditioner A in the driving diagnosis (step S112). When the air conditioner A is abnormal in the driving diagnosis (Yes in step S112), the control unit 1 stops the air conditioner A (step S114), and the diagnosis result is displayed on the display unit 71 of the remote controller 7. (Step S108). Further, when there is no abnormality in the air conditioner A in the driving diagnosis (in the case of No in step S112), the control unit 1 confirms whether or not the operation of the air conditioner A is continued for the person in the room Rm. (Step S113). Confirmation of the continuation of the operation of the air conditioner A may be performed by displaying on the display unit 71 of the remote controller 7 or by voice using the notification speaker 4. Moreover, you may confirm by methods other than these. An instruction from a person in the room Rm is given by the remote controller 7.

  When the continuation of the air conditioner A is selected (Yes in step S113), the control unit 1 performs the diagnosis result on the display unit 71 of the remote controller 7 while maintaining the current operation state (step S108). The diagnosis of the harmony machine A is finished. Note that the display of the diagnosis result is a display indicating that there is no abnormality.

  On the other hand, when an operation that does not continue the operation of the air conditioner A is performed with the remote controller 7 or a state where the operation is not performed continues for a certain period of time, the control unit 1 determines that the operation is not continued (step S113). No). And the control part 1 makes the air conditioner A a stop state (step S114), performs a diagnostic result on the display part 71 of the remote control 7 (step S108), and complete | finishes the diagnosis of the air conditioner A. Note that the display of the diagnosis result is a display indicating that there is no abnormality.

  As described above, in the air conditioner A according to the present embodiment, since the sound notification is performed using the disaster information and the speaker 4 for notification, the occurrence of a disaster (possibility of occurrence) to a person in the room Rm is quickly performed. I can tell you. In addition, when the air conditioner A receives disaster information (here, an earthquake early warning), the air conditioner A stops the power supply and enters a stopped state. And after an earthquake etc. settles, the presence or absence of abnormality of the air conditioner A and the abnormal part when there is abnormality are specified. And when there is an abnormality, it is possible to suppress the occurrence of secondary disasters such as electric shock due to electric leakage or fire due to short-circuiting by not performing the operation without noticing the abnormality. it can.

(Modification)
As described above, the control unit 1 stores the diagnosis result in the storage unit 3. When abnormality information is included in the diagnosis result stored in the storage unit 3, the control unit 1 does not accept the operation of the remote controller 7, that is, controls the air conditioner A not to be in an operating state. Also good. That is, in the air conditioner A, when an abnormality is found, the air conditioner A does not operate even when an operation start instruction is given. Thereby, even if the person in living room Rm does not confirm the display part 71 of the remote control 7, or when it performs operation start operation accidentally, the air conditioner A does not start operation. Thereby, generation | occurrence | production of secondary disasters, such as an electric shock by electric leakage and ignition by a short circuit, can be suppressed. In addition, there is a possibility of a secondary disaster due to the operation of the air conditioner A from the time when the disaster information is received until the initial diagnosis and / or the driving diagnosis is completed. It is preferable that the unit 1 does not accept the operation of the remote controller 7.

  In addition, you may make it reset the information of abnormality of the diagnostic result memorize | stored in the memory | storage part 3 when the air conditioner A is repaired or inspected. That is, if an abnormality is found in the air conditioner A, the operation may not be performed until repair or inspection is performed.

(Second Embodiment)
2nd Embodiment of the air conditioner concerning this invention is described with reference to drawings. FIG. 7 is a flowchart showing the operation of the air conditioner according to the second embodiment. In the air conditioner A of the present embodiment, the operation at the time of driving diagnosis is different, but the configuration of the air conditioner A is the same as that of the first embodiment.

  In the flowchart of the diagnostic operation shown in FIG. 7, step S401 is provided between step S103 and step S104 of the flowchart shown in FIG. Moreover, step S109 of the flowchart shown in FIG. 4 is excluded, and step S402 to step S404 are provided. Further, step S405 is provided instead of step S113. The other points are the same as those in the flowchart shown in FIG.

  As shown in FIG. 7, when the air conditioner A is operating when disaster information is received (Yes in step S103), the control unit 1 operates the air conditioner A, that is, a heat pump. It is memorize | stored in the memory | storage part 3 whether 2 was carrying out air_conditioning | cooling operation or heating operation (step S401). And the control part 1 makes the air conditioner A a stop state (step S104).

  Further, when it is determined in the initial diagnosis that there is no abnormality in the air conditioner A (No in step S107), the control unit 1 confirms whether the air conditioner A is in operation when the disaster information is received. (Step S402). Information on whether or not the vehicle is in operation is stored in the storage unit 3 in step S401. When the air conditioner A is in operation when the disaster information is received (Yes in step S402), the control unit 1 is in the operation state when the disaster information is received in order to perform the driving diagnosis. The heat pump 2 is driven, that is, the air conditioner A is operated (step S403). After the air conditioner A is driven, it waits until a predetermined time elapses in step S110.

  In addition, when the air conditioner A is stopped when the disaster information is received (No in step S402), the control unit 1 uses the room temperature sensor S1 to perform the diagnosis during driving. The temperature of Rm is measured, and the heat pump 2 is operated in an operation state corresponding to the temperature, that is, the air conditioner A is operated (step S404). For example, the control unit 1 performs a cooling operation of the heat pump 2 when the temperature in the living room Rm is high, and performs a heating operation of the heat pump 2 when the temperature in the living room Rm is low. After the air conditioner A is driven, it waits until a predetermined time elapses in step S110.

  And when there is no abnormality by the diagnosis at the time of a drive (in the case of No in step S112), the control part 1 confirms whether the air conditioner A was driving | operating when disaster information was received (step S405). When the air conditioner A is in operation (in the case of Yes in step S405), the control unit 1 performs the diagnosis result on the display unit 71 of the remote controller 7 while keeping the current operation state (step S108), and air conditioning The diagnosis of the machine A is finished. Note that the display of the diagnosis result is a display indicating that there is no abnormality.

  On the other hand, when the air conditioner is stopped when the disaster information is received (No in step S405), the control unit 1 stops the air conditioner A (step S114) and displays the diagnosis result. This is performed on the display unit 71 of the remote controller 7 (step S108), and the diagnosis of the air conditioner A is terminated. Note that the display of the diagnosis result is a display indicating that there is no abnormality.

  As described above, when the air conditioner A is in operation when the disaster information is received, the air conditioner A is driven in the operation state at the time when the disaster information is received to perform the driving diagnosis, and the vehicle is stopped. If this is the case, the set temperature is determined based on the temperature in the living room Rm, and the air conditioner A is driven in an operation state appropriate for the set temperature to perform the on-drive diagnosis. That is, when performing diagnosis based on the temperature of the refrigerant pipe or the temperature in the living room Rm as the driving diagnosis, the heat pump 2 exchanges more heat when operating according to the situation at that time. , Piping temperature change is easy to occur, diagnosis is easy. For example, when the temperature in the living room Rm is high, the heat pump 2 is operated for cooling, and when the temperature in the living room Rm is low, the heat pump 2 is operated for heating, so that a temperature difference in the refrigerant pipe is more likely to be generated and diagnosis is easier. As described above, by driving the air conditioner A and performing the driving diagnosis, it is possible to accurately perform the driving diagnosis.

  Further, when there is no abnormality in the initial diagnosis and the driving diagnosis, the air conditioner A is operated in the operation state when the disaster information is received. Thereby, the period when the inside of living room Rm is not air-conditioned can be shortened, and the comfort in living room Rm can be maintained high.
