  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
Initially, the structure and operation | movement outline | summary are demonstrated about the air conditioner of 1st Embodiment of this invention using FIGS. 1-3. FIG.1 and FIG.2 is a schematic block diagram of an air conditioner, respectively, and shows a state during cooling operation and heating operation. FIG. 3 is a block diagram showing the configuration of the air conditioner.

  The air conditioner 1 is a separate type air conditioner that includes an outdoor unit 10 and an indoor unit 30 as shown in FIGS. 1 and 2. And the air conditioner 1 is provided with the remote control 60 which is a remote control apparatus.

  The outdoor unit 10 is installed on, for example, an outdoor floor surface, and includes a rectangular box-shaped casing 11 composed of synthetic resin parts and sheet metal parts. A compressor 12, a switching valve 13, an expansion valve 14, an outdoor blower 15, an outdoor heat exchanger 16, and the like are housed inside the housing 11.

  The switching valve 13 is a four-way valve for switching the refrigerant flow direction in different operation modes such as cooling operation and heating operation. As the expansion valve 14, a valve whose opening degree can be controlled is used.

  The outdoor blower 15 is a combination of a propeller fan provided adjacent to the inner wall of the housing 11 and a motor that rotates the propeller fan. The housing 11 is provided with an air inlet and an air outlet (not shown). The outdoor heat exchanger 16 is disposed in the vicinity of the outdoor fan 15. When the outdoor blower 15 is driven, the outside air sucked into the housing 11 from the outside through the suction port passes through the outdoor heat exchanger 16 and heat exchange is performed between the outdoor heat exchanger 16 and the outside air. .

  The outdoor unit 10 is connected to the indoor unit 30 through two refrigerant pipes 17 and 18. Liquid refrigerant flows through the refrigerant pipe 17, and a thinner pipe than the refrigerant pipe 18 is used. Therefore, the refrigerant pipe 17 is sometimes referred to as “liquid pipe”, “narrow pipe”, or the like. A gaseous refrigerant flows through the refrigerant pipe 18, and a thicker pipe than the refrigerant pipe 17 is used. Therefore, the refrigerant pipe 18 may be referred to as “gas pipe”, “thick pipe”, or the like, for example. For example, HFC R410A or R32 is used as the refrigerant.

  Regarding the refrigerant pipes 19 and 20 inside the outdoor unit 10, the refrigerant pipe 19 connected to the refrigerant pipe 17 is provided with a two-way valve 21, and the refrigerant pipe 20 connected to the refrigerant pipe 18 is provided with a three-way valve 22. It is done. The two-way valve 21 and the three-way valve 22 are closed when the refrigerant pipes 17 and 18 are removed from the outdoor unit 10 to prevent the refrigerant from leaking from the outdoor unit 10 to the outside. When the refrigerant needs to be recovered from the outdoor unit 10 or the entire air conditioner 1, the recovery is performed through the three-way valve 22.

  The indoor unit 30 is installed near the ceiling of an indoor wall surface, for example, has a horizontally long shape extending in the horizontal direction, and includes a housing 31 made of synthetic resin parts. The casing 31 accommodates the indoor blower 32, the indoor heat exchanger 33, and the like shown in FIGS.

  The indoor blower 32 is a combination of, for example, a cross flow fan that extends horizontally in the horizontal direction along the shape of the housing 31 and a motor that rotates the fan. The housing 31 is provided with an air inlet and an air outlet (not shown). The indoor heat exchanger 33 extends in the horizontal direction like the cross flow fan, and is configured by combining three pieces (indoor heat exchangers 33A, 33B, 33C). The three indoor heat exchangers 33 are arranged so as to cover the top and front of the crossflow fan of the indoor blower 32. The refrigerant sent out from the outdoor unit 10 flows into the indoor heat exchanger 33. When the indoor blower 32 is driven, the indoor air sucked into the housing 31 through the suction port passes through the indoor heat exchanger 33, and the indoor heat exchanger 33 exchanges heat with the indoor air.

  In order to control the operation of the air conditioner 1, it is indispensable to know the temperature of each place. For this reason, the temperature detection part is arrange | positioned in several places of the outdoor unit 10 and the indoor unit 30. FIG.

  In the outdoor unit 10, the temperature detection unit 23 is disposed in the outdoor heat exchanger 16, the temperature detection unit 24 is disposed in the discharge pipe 12 a serving as the discharge unit of the compressor 12, and the suction pipe serving as the suction unit of the compressor 12.

In the indoor unit 30, a temperature detection unit 34 is disposed in the indoor heat exchanger 33, and a temperature detection unit 35 for room temperature detection is disposed at a predetermined location inside the housing 31. Each of the temperature detectors 23, 24, 25, 26, 27, 34, and 35 is formed of, for example, a thermistor.

  In addition, the temperature detection part 35 which detects indoor temperature functions as an environment detection part for detecting the indoor environment.

  The indoor unit 30 includes a human body detection unit 36, a notification unit 37, and a communication unit 38.

  The human body detection unit 36 is disposed in the vicinity of the exterior of the indoor unit 30 in order to detect the presence of a person in the room. The human body detection unit 36 is configured by a human sensor that detects the presence of a person using, for example, infrared rays, ultrasonic waves, or visible light.

  The notification unit 37 is disposed in the vicinity of the exterior of the indoor unit 30 in order to notify the surroundings by, for example, display, sound, light, or the like. The notification unit 37 includes a display panel made up of a liquid crystal panel or the like, a light emitting unit made up of a speaker, an LED (Light Emitting Diode), or the like.

  The communication unit 38 is disposed in the vicinity of the exterior of the indoor unit 30 in order to transmit and receive information to and from the remote controller 60. The communication unit 38 includes, for example, an infrared light emitting unit and a light receiving unit.

  The remote controller 60 can remotely control the air conditioner 1. The remote controller 60 includes an operation control unit 61, a display unit 62, an operation unit 63, a notification unit 64, and a communication unit 65 shown in FIG. The operation control unit 61 includes a calculation unit, a storage unit, and the like (not shown), receives information from each component of the remote control 60 and controls them.

  The display unit 62 is provided on the surface of the remote controller 60, and includes a display panel made of, for example, a liquid crystal panel or a light emitting unit made of LEDs. The operation unit 63 is provided on the surface of the remote controller 60 adjacent to the display unit 62 and includes various operation buttons. As the operation buttons, for example, a switching button for cooling operation or heating operation, a stop button, a temperature adjustment button, a wind direction switching button, a timer button, and the like are provided.

  Here, the air conditioner 1 has a timer mode for switching on / off of the air conditioning operation at a preset time as a control mode of the air conditioning operation. By operating the timer button of the remote controller 60, the user can set the operation in the on timer mode in which the operation is automatically started at the reserved time and the operation in the off timer mode in which the operation is automatically stopped at the reserved time.

  The notification unit 64 shares the display panel and the light emitting unit of the display unit 62, and also includes, for example, a speaker and a vibration unit. The notification unit 64 notifies the surroundings of information by display, sound, light, vibration, or the like.

  The communication unit 65 is disposed in the vicinity of the exterior of the remote controller 60 in order to transmit and receive information to a main control unit 50 described later of the indoor unit 30. The communication unit 65 includes, for example, an infrared light emitting unit and a light receiving unit.

  Further, the indoor unit 30 accommodates a main control unit 50 shown in FIG. 3 inside the housing 31 in order to control the operation of the entire air conditioner 1 including the outdoor unit 10. The main control unit 50 includes a calculation unit, a storage unit, and the like (not shown), and performs a series of control operations such that the room temperature reaches a target value set by the user based on programs and data stored and input in the storage unit. Realize air conditioning operation.

  The main control unit 50 issues an operation command to the compressor 12, the switching valve 13, the expansion valve 14, the outdoor blower 15, and the indoor blower 32. The main control unit 50 receives output signals corresponding to temperature information detected by the temperature detection units 23 to 27 and the temperature detection units 34 and 35. The main control unit 50 issues operation commands to the compressor 12, the outdoor blower 15, and the indoor blower 32 while referring to output signals from the temperature detection units 23 to 27 and the temperature detection units 34 and 35, and the switching valve 13. A state switching command is issued to the expansion valve 14. Then, the main control unit 50 obtains information on the presence and position of a person in the room based on the output signal from the human body detection unit 36, and automatically adjusts the wind direction by operating a louver (not shown) of the indoor unit 30, for example. It is also possible to do.

  FIG. 1 shows a state in which the air conditioner 1 is performing a cooling operation or a defrosting operation. At this time, the compressor 12 circulates the refrigerant in a cooling mode, that is, in a circulation mode in which the refrigerant discharged from the compressor 12 first enters the outdoor heat exchanger 16. The refrigerant circulates in the direction of the arrow drawn close to the refrigerant pipes 17 to 20 in FIG.

  The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 12 enters the outdoor heat exchanger 16 where heat exchange with the outside air is performed. The refrigerant dissipates heat to the outside air and condenses. The refrigerant that has condensed into a liquid is decompressed by the expansion valve 14 from the outdoor heat exchanger 16. The decompressed refrigerant is sent to the indoor heat exchanger 33, expands to a low temperature and low pressure, and lowers the surface temperature of the indoor heat exchanger 33. The indoor heat exchanger 33 whose surface temperature has dropped absorbs heat from the room air, and thereby the room air is cooled. After the heat absorption, the low-temperature gaseous refrigerant returns to the compressor 12. The air flow generated by the outdoor blower 15 promotes heat dissipation from the outdoor heat exchanger 16, and the air flow generated by the indoor blower 32 promotes heat absorption of the indoor heat exchanger 33. In the defrosting operation, the indoor fan 32 does not operate, and heat exchange by airflow is not actively performed indoors.

  FIG. 2 shows a state where the air conditioner 1 is performing a heating operation. At this time, the switching valve 13 is switched, and the refrigerant flow is reversed from that during the cooling operation. The compressor 12 circulates the refrigerant in a circulation mode during heating, that is, in a circulation mode in which the refrigerant discharged from the compressor 12 first enters the indoor heat exchanger 33. The refrigerant circulates in the direction of the arrow drawn close to the refrigerant pipes 17 to 20 in FIG.

  The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 12 enters the indoor heat exchanger 33 where heat exchange with the indoor air is performed. The refrigerant dissipates heat to the room air, and the room air is warmed. The refrigerant that has radiated heat and condensed to become liquid is decompressed by the expansion valve 14 from the indoor heat exchanger 33. The decompressed refrigerant is sent to the outdoor heat exchanger 16 and expands to a low temperature and low pressure, thereby lowering the surface temperature of the outdoor heat exchanger 16. The outdoor heat exchanger 16 whose surface temperature has dropped absorbs heat from the outside air. After the heat absorption, the low-temperature gaseous refrigerant returns to the compressor 12. The air flow generated by the indoor blower 32 promotes heat dissipation from the indoor heat exchanger 33, and the air flow generated by the outdoor blower 15 promotes heat absorption by the outdoor heat exchanger 16.

  The main control unit 50 has a control mode called a notification mode in addition to control modes such as a cooling operation mode, a heating operation mode, a dehumidifying operation mode, an automatic operation mode, and a timer mode. Like the other control modes, the notification mode can be switched between valid and invalid by an operation button provided on the operation unit 63 of the remote controller 60.

  In the notification mode, the notification unit 37 of the indoor unit 30 and the notification unit 64 of the remote controller 60 are used. In the notification mode, the main control unit 50 notifies when the indoor temperature detected by the temperature detection unit 35 reaches a first predetermined temperature and the human body detection unit 36 detects the presence of a person in the room. The parts 37 and 64 are notified of temperature information.

  Next, an example of the notification mode of the air conditioner 1 will be described along the flow shown in FIG. FIG. 4 is a flowchart showing an operation flow of the air conditioner 1 in the notification mode.

  When the notification mode is started (start of FIG. 4), the main control unit 50 confirms the output of the temperature detection unit 35 in step # 101 and the room temperature is equal to or higher than a first predetermined temperature (for example, 35 ° C.) set in advance. It is determined whether or not. If the room temperature has not reached the first predetermined temperature, the determination in step # 101 is repeated until the room temperature reaches the predetermined value. If the room temperature is equal to or higher than the first predetermined temperature, the process proceeds to step # 102.

  In step # 102, the main control unit 50 confirms the output of the human body detection unit 36 and determines whether or not there is a person in the room. If there is no person in the room, the process returns to step # 101 to determine the temperature in the room again. If there is a person in the room, the process proceeds to step # 103.

  In step # 103, the main control unit 50 causes the notification units 37 and 64 to notify the temperature information. The notification units 37 and 64 notify the surroundings that the room temperature is equal to or higher than a first predetermined temperature (for example, 35 ° C.) by display or sound. The notification units 37 and 64 may notify that there is a risk of heat stroke if left as it is. The notification units 37 and 64 can also notify by a chime sound, a buzzer sound, or a bell sound. Further, the notification units 37 and 64 may notify by flashing LED light (for example, red). Further, the notification unit 64 can execute the notification by vibrating the remote controller 60 itself. A person (such as a user) who has received the notification can deal with the problem by starting the cooling operation of the air conditioner 1.

  The processing of step # 101 to step # 103, that is, notification, can be continuously executed at predetermined time intervals (for example, every 5 minutes). Meanwhile, the air conditioner 1 performs notification when the room temperature detected by the temperature detection unit 35 reaches a first predetermined temperature (for example, 35 ° C. or more) and there is a person in the room. On the other hand, even if the indoor temperature detected by the temperature detection unit 35 has reached a predetermined first predetermined temperature (for example, 35 ° C. or higher), the air conditioner 1 does not perform notification when there is no person in the room.

  In the present embodiment, the room is relatively hot and, for example, it is possible to deal with a dangerous state that may cause heat stroke. However, the room may be relatively cold and may develop hypothermia, for example. It may be possible to deal with a dangerous situation. In this case, the air conditioner 1 performs notification when the indoor temperature detected by the temperature detection unit 35 reaches a predetermined first predetermined temperature (for example, 18 ° C. or less) and there is a person in the room.

There is.

  The air conditioner 1 of 2nd Embodiment performs the notification mode of the operation | movement flow shown in FIG.

  After the notification is executed in Step # 203, the main control unit 50 automatically starts the cooling operation in Step # 204. Thereby, the countermeasure for avoiding the onset of heat stroke is automatically executed. In addition, when the process of step # 201-step # 203 is continuously performed for every predetermined time (for example, every 5 minutes), the cooling operation of step # 204 is also continued as it is.

  On the other hand, after starting the cooling operation, in Step # 205, has the main controller 50 reached a predetermined second predetermined temperature (for example, 28 ° C.) that is lower than the first predetermined temperature (for example, 35 ° C.)? Judgment is made or not. If the room temperature is not lower than the second predetermined temperature, the process returns to step # 201 to determine the room temperature again. When the room temperature becomes equal to or lower than the second predetermined temperature, the process proceeds to step # 206. If no more people are present in the room in step # 202, the process proceeds to step # 206.

  In step # 206, the main control unit 50 automatically ends the cooling operation started in step # 204. That is, when the room temperature reaches the second predetermined temperature, or when there is no more person in the room, the main control unit 50 ends the cooling operation started in the notification mode in any case.

<Third Embodiment>
Next, the air conditioner of 3rd Embodiment of this invention is demonstrated using FIG. FIG. 6 is a flowchart showing an operation flow of the notification mode of the air conditioner.

There is.

  The air conditioner 1 of 3rd Embodiment performs the notification mode of the operation | movement flow shown in FIG.

  After the notification is executed in step # 303, the main control unit 50 automatically starts the cooling operation in step # 304.

  After the start of the cooling operation, in step # 305, the main controller 50 has reached (decreased) a predetermined second predetermined temperature (for example, 28 ° C.) in which the room temperature is lower than the first predetermined temperature (for example, 35 ° C.). Determine whether or not. When the room temperature becomes equal to or lower than the second predetermined temperature, the process proceeds to step # 306. In step # 306, the main control unit 50 automatically ends the cooling operation started in step # 304.

  On the other hand, when there is no more person in the room in step # 302, the process returns to step # 301 to determine the room temperature again. That is, when the room temperature does not reach the second predetermined temperature, the main control unit 50 does not end the cooling operation started in the notification mode even if there is no more person in the room.

<Fourth embodiment>
Next, the air conditioner of 4th Embodiment of this invention is demonstrated using FIG. FIG. 7 is a flowchart showing an operation flow of the notification mode of the air conditioner. Since the basic configuration of this embodiment is the same as that of the first embodiment described above, the same components as those of the first embodiment are denoted by the same reference numerals as those of the previous embodiment, and the description thereof is omitted. There is.

  The air conditioner 1 of 4th Embodiment performs the notification mode of the operation | movement flow shown in FIG.

  If there is a person in the room in step # 402, the main control unit 50 determines in step # 403 whether or not the operation unit 63 has accepted the operation. If the operation unit 63 has not accepted the operation, the process proceeds to step # 403 where notification is executed. When the operation unit 63 accepts the operation, the notification is not executed, and the process returns to step # 401 to determine the indoor temperature again.

  Thus, when the user performs an operation when the notification is continuously executed every predetermined time (for example, every 5 minutes), the notification every predetermined time is suspended.

<Fifth Embodiment>
Next, the air conditioner of 5th Embodiment of this invention is demonstrated using FIG. FIG. 8 is a flowchart showing an operation flow of the notification mode of the air conditioner. Since the basic configuration of this embodiment is the same as that of the first embodiment described above, the same components as those of the first embodiment are denoted by the same reference numerals as those of the previous embodiment, and the description thereof is omitted. There is.

  The air conditioner 1 of 5th Embodiment performs the notification mode of the operation | movement flow shown in FIG.

  If there is a person in the room in step # 502, the main control unit 50 determines in step # 503 whether the timer mode is enabled. If the timer mode is not enabled, the process proceeds to step # 505 and notification is executed. If the timer mode is enabled, the process proceeds to step # 504.

  In step # 504, the main control unit 50 determines whether or not the period until the on-time of the cooling operation set in the timer mode is a predetermined value or more. The predetermined value relating to the period until the on-time of the cooling operation may be set in advance to a constant value such as 10 minutes, or may be set in advance so that the period becomes shorter as the indoor temperature increases. When the period until the on-time of the cooling operation is equal to or greater than the predetermined value, the process proceeds to step # 505 and notification is executed. On the other hand, when the period until the on-time of the cooling operation is less than the predetermined value, the notification is not executed, and the process returns to step # 501 to determine the indoor temperature again.

  In this way, the notification is executed when the period until the on-time of the cooling operation set in the timer mode is relatively long, and the notification is stopped when the period until the on-time of the cooling operation is relatively short.

A positive voltage is applied to the positive discharge electrode, and hydrogen ions generated by corona discharge combine with moisture in the air to generate positive ions mainly composed of H ⁺ (H ₂ O) m. A negative voltage is applied to the negative discharge electrode, and oxygen ions generated by corona discharge combine with moisture in the air to generate negative ions mainly composed of O ₂ ⁻ (H ₂ O) n. Here, m and n are arbitrary natural numbers. H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of odorous components and airborne bacteria in the air and surround them.

Then, as shown in the formulas (1) to (3), the active species [.OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) are aggregated and formed on the surface of the microorganism or the like by collision. Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, the ion generator 41 discharges the air flowing through the ventilation path so as to include positive ions and negative ions generated by the discharge at the positive discharge electrode and the negative discharge electrode, thereby deodorizing and sterilizing the room. It can be carried out.

H ⁺ (H ₂ O) m + O ₂ ⁻ (H ₂ O) n → OH + 1 / 2O ₂ + (m + n) H ₂ O (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)
