[0009] (Findings that formed the basis of this disclosure) At the time when the inventors arrived at the idea of ​​the present disclosure, there was a technique for providing an electrostatic atomizer in an air conditioner to remove indoor odors and neutralize allergens such as pollen.

The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment) The configuration of an air conditioner 1 according to an embodiment will be described below with reference to Figs.

[0013] [1-1.Configuration] [1-1-1. Air Conditioning Equipment Configuration] FIG. 1 is a schematic diagram of an air conditioner 1 according to the first embodiment.

[0014] As shown in FIG. 1, an air conditioner 1 according to this embodiment has an indoor unit 5 arranged in a room Rin to be air-conditioned, and an outdoor unit 10 arranged in an outdoor room Rout.

[0015] The indoor unit 5 is provided with an indoor heat exchanger 15 that exchanges heat with the indoor air A1, and an indoor blower 60 that draws the indoor air A1 into the indoor unit 5 and blows the indoor air A1 into the room Rin after exchanging heat with the indoor heat exchanger 15. The indoor heat exchanger 15 is used for cooling operation that cools the indoor air in a refrigeration cycle using a refrigerant (not shown) circulating inside the indoor heat exchanger 15, dehumidification operation that removes moisture from the indoor air, and the like.

[0016] The outdoor unit 10 is provided with an outdoor heat exchanger 30 that exchanges heat with outdoor air 73, and an outdoor blower 40 that draws the outdoor air 73 into the outdoor unit 10 and blows the outdoor air 77 out to the outdoor Rout after exchanging heat with the outdoor heat exchanger 30. The outdoor unit 10 is also provided with a compressor 35, an expansion mechanism 50, and a four-way valve 45 that perform a refrigeration cycle with the indoor heat exchanger 15 and the outdoor heat exchanger 30.

[0017] The outdoor unit 10 and the indoor unit 5 are connected by a refrigerant pipe 56 to form a predetermined refrigeration cycle circuit. The indoor heat exchanger 15, the outdoor heat exchanger 30, the compressor 35, the expansion mechanism 50, and the four-way valve 45 are each connected by a refrigerant pipe 56. In cooling operation and dehumidification operation (weak cooling operation), the air conditioner 1 forms a refrigeration cycle in which the refrigerant flows from the compressor 35 through the four-way valve 45, the outdoor heat exchanger 30, the expansion mechanism 50, and the indoor heat exchanger 15 in that order, before returning to the compressor 35. In heating operation, the air conditioner 1 forms a refrigeration cycle in which the refrigerant flows from the compressor 35 through the four-way valve 45, the indoor heat exchanger 15, the expansion mechanism 50, and the outdoor heat exchanger 30 in that order, before returning to the compressor 35.

[0018] The outdoor unit 10 is equipped with an outdoor air dew point detection sensor 107 (see FIG. 3) that measures the dew point of the outdoor air. The outdoor unit 10 is further equipped with an outdoor air temperature and humidity detection sensor 109 (see FIG. 3) that detects the temperature and humidity of the outdoor air. Of course, the outdoor air dew point detection sensor 107 and the outdoor air temperature and humidity detection sensor 109 may be provided in the indoor unit 5 as long as they perform their functions.

[0019] Next, the configuration of the indoor unit 5 will be described. FIG. 2 is a side cross-sectional view of the indoor unit 5. As shown in FIG. 2, the indoor unit 5 includes a housing 97 that is attached to a wall surface inside a room.

[0020] An air intake 95 for drawing in indoor air is provided on the top surface of the housing 97. An indoor temperature and humidity detection sensor 105 for measuring the temperature and humidity of the indoor air is provided near the air intake 95. It is desirable that the indoor temperature and humidity detection sensor 105 can also measure the dew point of the indoor air. An air outlet 91 for blowing air toward the room Rin is provided on the bottom surface of the housing 97. Both the air intake 95 and the air outlet 91 are formed across the entire width of the housing 97. An indoor heat exchanger 15 is housed inside the housing 97. The indoor heat exchanger 15 is formed in a substantially inverted V shape when viewed from the side, and is arranged so as to separate the space between the air intake 95 and the air outlet 91 inside the housing 97. This ensures that the indoor air A1 drawn in through the air intake 95 always passes through the indoor heat exchanger 15 before reaching the air outlet 91. A refrigerant temperature detection sensor 103 is provided to measure the temperature of the refrigerant flowing inside the indoor heat exchanger 15.

[0021] An indoor blower 60 is disposed inside the indoor heat exchanger 15. The indoor blower 60 is configured to be driven to rotate by a blower drive motor (not shown) to draw in indoor air through the intake port 95, pass the air through the indoor heat exchanger 15 to exchange heat, and then blow the air out of the outlet 91 into the room Rin.

[0022] A left-right air deflector 87 that adjusts the left-right direction of the air being blown out is provided near the air outlet 91 so as to be able to swing left and right. The air direction of the left-right air deflector 87 can be adjusted manually or by an air deflector drive motor (not shown). Below the left and right airflow direction vanes 87, up and down airflow direction vanes 89 are provided so as to be able to swing freely, for adjusting the up and down wind direction of the air being blown out. The vertical airflow direction vane 89 can automatically adjust the vertical airflow direction by an airflow direction vane drive motor (not shown).

[0023] The outdoor unit is provided with a ventilation device 25. A ventilation fan (not shown) is provided inside the ventilation device 25. One end of a ventilation duct 20 is connected to the ventilation device 25. The ventilation duct 20 is led into the interior of the housing 97 of the indoor unit 5. As shown in Fig. 2, air guide members 81 are arranged on both sides of the indoor heat exchanger 15 of the indoor unit 5. The air guide members 81 are formed so as to bend obliquely upward from the rear of the housing 97. The rear end of the air guide member 81 is bent downward and connected to the ventilation duct 20. The front end of the air guide member 81 extends to the front side of the indoor heat exchanger 15, and a nozzle 81a facing the lower front side of the indoor heat exchanger 15 is attached to the front end of the air guide member 81.

[0024] In this embodiment, by driving the ventilation fan, exhaust operation can be performed in which indoor air A1 is exhausted to the outside Rout via the nozzle 81a, the air guide member 81, and the ventilation duct 20 in that order, or air supply operation can be performed in which outdoor air is supplied into the room via the ventilation duct 20, the air guide member 81, and the nozzle 81a in that order.

[0025] Furthermore, an electrostatic atomizer 85 is disposed inside the housing 97 near the outlet 91. The electrostatic atomizer 85 includes, for example, a discharge unit that discharges electricity to supplied water to generate a mist containing charged atomized water particles, and a power supply circuit that generates a high voltage to be applied to the discharge unit. The discharge unit and power supply circuit are not shown. The electrostatic atomizer 85 generates a mist containing charged atomized water particles to suppress viruses, mold, allergy-causing substances, bacteria, etc. in the air and to deodorize. The charged atomized water particles contain active ingredients such as electrostatic mist that exhibit disinfecting and deodorizing effects.

[0026] The indoor unit 5 is provided with drainage channels called drain pans 144 and 146 that receive condensed water that is cooled and condensed near the indoor heat exchanger 15.

[0027] An indoor temperature and humidity detection sensor 105 for measuring the temperature and humidity of the indoor air is provided near the air intake 95. It is desirable that the indoor temperature and humidity detection sensor 105 be able to measure the dew point Td of the indoor air. A refrigerant temperature detection sensor 103 is provided to measure the temperature of the refrigerant flowing inside the indoor heat exchanger 15.

[0028] [1-1-2. Control configuration] Next, the control configuration of the first embodiment will be described. FIG. 3 is a block diagram showing the configuration of this embodiment. The indoor unit 5 is equipped with a control unit 7. The control unit 7 controls each device of the air conditioner 1. The control unit 7 includes a processor, a memory, and a timer. The control of the control unit 7 is executed by the processor processing a program stored in the memory.

[0029] The control unit 7 includes a communication unit 101, and the communication unit 101 is capable of communicating with a remote control 70 operated by a user, the indoor unit 5, and the outdoor unit 10. That is, the control unit 7 controls the drive of the compressor 35, outdoor blower 40, four-way valve 45, expansion mechanism 50, outdoor heat exchanger 30, and ventilation device 25 of the outdoor unit 10, and the indoor heat exchanger 15, indoor blower 60, and electrostatic atomizer 85 of the indoor unit 5, through operation of the remote control 70 by the user. The communication unit 101 also sends and receives signals to and from the indoor unit 5 and the outdoor unit 10 using wired or wireless communication means, enabling the control unit 7 to control the indoor unit 5 and the outdoor unit 10.

[0030] The outdoor unit 10 is equipped with an outdoor air dew point detection sensor 107 that detects the dew point of the outdoor air, and an outdoor air temperature and humidity detection sensor 109 that detects the temperature and humidity of the outdoor air. The outdoor air dew point detection sensor 107 and the outdoor air temperature and humidity detection sensor 109 may be a single common sensor. The control unit 7 is connected to the outdoor air dew point detection sensor 107 and the outdoor air temperature and humidity detection sensor 109 via the communication unit 101 and acquires various measurement values.

[0031] In addition, the control unit 7 is connected to a refrigerant temperature detection sensor 103 that measures the temperature of the refrigerant flowing inside the indoor heat exchanger 15, and an indoor temperature and humidity detection sensor 105 that measures the temperature, humidity, and dew point of the indoor air, and acquires various measurement values.

[0032] The control unit 7 controls the operation in normal operation modes such as a cooling operation mode, a cooling and dehumidifying operation mode, and a heating operation mode. Of course, the operation may also have a dehumidifying operation mode, a fan operation mode, a clothes drying operation mode, etc.

[0033] In this embodiment, the control unit 7 performs control in an odor component removal mode. The odor component removal mode is started when the user operates the odor component removal mode switch on the remote control 70. In this embodiment, when the odor component removal mode switch is operated, the control unit 7 starts the cooling operation and reduces the surface temperature of the indoor heat exchanger 15 to a temperature below the dew point of the indoor air. Whether the surface temperature of the indoor heat exchanger 15 has reached or exceeded the dew point is determined, for example, based on the temperature of the refrigerant sent to the indoor heat exchanger 15 measured by the refrigerant temperature sensor 103 and the humidity of the indoor air measured by the indoor temperature and humidity detection sensor 105. The moisture in the room that has been cooled on the surface of the indoor heat exchanger 15 condenses when the temperature drops below the dew point, producing condensed water. Odor components floating in the room are collected and removed in the condensed water.

[0034] When operating in the odor component removal mode, the control unit 7 controls the rotation speed of the indoor blower 15 to a predetermined rotation speed or less, thereby keeping the condensed water from drying.

[0035] The above-mentioned predetermined rotation speed is, for example, 1000 rpm, and is preferably, for example, 400 rpm. [1-2. Air conditioner control method] Next, a method for controlling the air conditioner 1 in the odor component removal mode using the air conditioner 1 described above will be described with reference to a flowchart.

[0036] FIG. 4 is a flowchart showing control operations including an odor component removal mode and an exhaust mode, which will be described later, in the air conditioner 1 according to the present embodiment.

[0037] The control unit 7 determines whether the odor component removal mode switch has been operated using the remote control 70 or the like (step SA1). If it is determined that the odor component removal mode switch has been operated (step SA1: YES), control is performed in the odor component removal mode. That is, the control unit 7 operates the electrostatic atomization device 85 to generate electrostatic mist A3, and drives the indoor blower 15 at a predetermined rotation speed or less (step SA2). The control unit 7 controls the ventilation device 25 to perform an air supply operation of the outdoor air 75 (step SA3). The control unit 7 causes the air conditioning device 1 to execute a refrigeration cycle in which the refrigerant flows sequentially from the compressor 35 through the four-way valve 45, the outdoor heat exchanger 30, the expansion mechanism 50, and the indoor heat exchanger 15 before returning to the compressor 35, and performs dehumidification operation to condense moisture in the indoor air A1 on the surface of the indoor heat exchanger 15 (step SA4).

[0038] As a result, moisture in the indoor air A1 condenses on the surface of the indoor heat exchanger 15. Odor components contained in the indoor air are adsorbed by this condensed water.

[0039] Next, the control unit 7 determines whether or not the control in the odor component removal mode has been performed for a predetermined time (step SA5). If it is determined that the odor component removal mode has been performed for a predetermined time (step SA5: YES), the control unit 7 performs control in the electrostatic mist circulation mode. That is, the control unit 7 stops the ventilation fan and stops the air supply operation (step SA6). The control unit 7 controls the upper and lower air direction vanes 89 to face upward, so that the air blown out from the air outlet rises along the front of the indoor unit and is sucked back into the indoor unit through the air intake 95, circulating the air by a so-called short circuit.

[0040] As a result, the indoor air A1 containing the electrostatic mist N (see FIG. 5) generated by the electrostatic atomization device 85 is circulated (step SA7). By controlling in this way, it is possible to make it easier for the electrostatic mist to decompose odorous components and other allergens.

[0041] The control unit 7 determines whether or not control in the electrostatic mist circulation mode has been performed for a predetermined time (step SA8). If it is determined that control in the electrostatic mist circulation mode has been performed for a predetermined time (step SA8: YES), control in the internal cleaning mode is performed. That is, the control unit 7 stops the electrostatic atomization device 85 and performs internal cleaning operation (step SA9). Specifically, the indoor blower 60 continues to operate to dry the moisture condensed on the surface of the indoor heat exchanger 15.

[0042] If the odor component removal mode switch has not been operated (step SA1: NO), the unit waits. Also, if control in the odor component removal mode has not been performed for a predetermined time (step SA5: NO), operation in the odor component removal mode continues. If control in the electrostatic mist circulation mode has not been performed for a predetermined time (step SA8: NO), operation in the electrostatic mist circulation mode continues.

[0043] 5 is a schematic diagram showing operation in odor component removal mode of the air conditioner 1 according to the present embodiment. In odor component removal mode, indoor air A1 and electrostatic mist A3 are blown out from the air outlet 91. At the same time, outdoor air 75 is supplied to the indoor unit 5 from the air guide member 81, supplying moisture contained in the outdoor air 75 and increasing the amount of condensed water, thereby improving odor component removal performance.

[0044] 6 is a schematic diagram showing operation in electrostatic mist circulation mode of the air conditioner 1 according to the present embodiment. To prevent a decrease in the electrostatic mist that breaks down odorous components contained in the indoor air, the control unit 7 controls the ventilation device 25 to stop the air supply operation. By performing such control, indoor air A1+A3 containing electrostatic mist is circulated within the room.

[0045] [1-3. Effects, etc.] As described above, the air conditioner 1 in this embodiment is an air conditioner 1 that includes an outdoor unit 10 equipped with a ventilation device 25 that ventilates indoor air A1, an indoor unit 5 equipped with an electrostatic atomization device 85 inside a housing 97, and a control unit 7 that controls the outdoor unit 10 and the indoor unit, and is characterized in that the control unit 7 controls the ventilation device 25 in an odor component exhaust mode in which the ventilation device 25 performs air supply operation and dehumidification operation using the indoor heat exchanger 15 while the electrostatic atomization device 85 generates electrostatic mist.

[0046] This allows the electrostatic mist to decompose and remove odorous components, while the supply of moist outside air increases the amount of condensed water, effectively removing odorous components and reducing indoor odors.

[0047] Furthermore, the control unit 7 of the air conditioning apparatus 1 in this embodiment is characterized by controlling in an air supply stop mode that stops the air supply operation by the ventilation device 25 during electrostatic mist circulation operation in which the electrostatic atomization device 85 circulates electrostatic mist in the room Rin.

[0048] This eliminates the air intake noise during electrostatic mist circulation operation of electrostatic atomizer 85, enabling quiet operation. Furthermore, because electrostatic mist A3 is less likely to thin, this has the effect of accelerating the decomposition of odorous components contained in indoor air A1.

[0049] Furthermore, the control method for the air conditioner 1 in this embodiment is a control method for the air conditioner 1 in which the control unit 7 controls the outdoor unit 10 equipped with the ventilation device 25 that ventilates the indoor air and the indoor unit 5 equipped with the electrostatic atomization device 85 inside the housing 97, and the control unit 7 is characterized in that while the electrostatic atomization device 85 generates electrostatic mist, the ventilation device 25 performs air supply operation and executes an odor component removal mode in which a dehumidification operation is performed using the indoor heat exchanger 15. This allows the electrostatic mist to decompose and remove odorous components, while the supply of moist outside air increases the amount of condensed water, effectively removing odorous components and reducing indoor odors.

[0050] (Other embodiments) In another embodiment, the air conditioning apparatus 1 may be characterized by including a refrigerant temperature detection sensor 103 that measures the temperature of the indoor heat exchanger 15, i.e., the refrigerant temperature Te, and an outdoor air dew point detection sensor 107 that measures the dew point Td of the outdoor air 75, and the control unit 7 stopping the air supply operation by the ventilation device 25 when the refrigerant temperature Te is higher than the outdoor air dew point Td.

[0051] As a result, when the refrigerant temperature Te is higher than the outdoor air dew point Td, the ventilation device 25 does not perform air supply operation, preventing the condensed water from being reduced by dry outdoor air, thereby achieving the effect of maintaining odor removal efficiency.

[0052] Furthermore, the air conditioning device 1 in this embodiment is equipped with an indoor temperature and humidity detection sensor 105 that measures the temperature Tin and humidity Hin of the indoor air, and an outdoor temperature and humidity detection sensor 109 that measures the temperature Tout and humidity Hout of the outdoor air 75, and when Tout is higher than Tin, the control unit 7 may cause the ventilation device 25 to perform air supply operation.

[0053] When the indoor air temperature Tin is low, the temperature range in which cooling is possible becomes narrower, making it difficult to condense condensation. Therefore, by limiting air supply operation to when Tout is higher than Tin, air supply operation is performed only when an increase in condensation due to the intake of outdoor air is expected, which can have the effect of increasing the efficiency of odor removal.

[0054] Furthermore, the air conditioner 1 in this embodiment is characterized in that, when the Hin is equal to or less than a predetermined value, the control unit 7 causes the ventilation device 25 to perform air supply operation. This allows for an increase in the amount of condensation water when the indoor air is dry by supplying moist outdoor air, thereby improving the efficiency of odor removal caused by condensation.

[0055] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalents.

[0056] (Addendum) The above description of the embodiments discloses the following techniques.

[0057] (Technology 1) An air conditioning system comprising an outdoor unit equipped with a ventilation device that ventilates indoor air, an indoor unit equipped with an electrostatic atomizer inside the housing, and a control unit that controls the outdoor unit and the indoor unit, characterized in that the control unit controls the air conditioning system in an odor component exhaust mode in which the ventilation device performs air supply operation and dehumidification operation using the indoor heat exchanger while the electrostatic atomizer generates electrostatic mist. This configuration decomposes and removes odorous components using electrostatic mist, and also increases the amount of condensed water by supplying moist outside air, effectively removing odorous components. As a result, odors in the room can be reduced.

[0058] (Technology 2) The air conditioning apparatus according to Technology 1, characterized in that the control unit controls in an air supply stop mode that stops the air supply operation of the ventilation device during electrostatic mist circulation operation in which the electrostatic atomizer circulates electrostatic mist in the room. This configuration eliminates the air intake noise during electrostatic mist circulation operation of electrostatic atomizer 85, enabling quiet operation. Furthermore, because electrostatic mist A3 is less likely to thin, it can also promote the decomposition of odorous components contained in indoor air A1.

[0059] (Technology 3) An air conditioning apparatus according to Technology 1 or Technology 2, characterized in that it is provided with a refrigerant temperature detection sensor that measures the temperature Te of the indoor heat exchanger, and an outdoor air dew point detection sensor that measures the dew point Td of the outdoor air, and the control unit stops the air supply operation by the ventilation device when Te is higher than Td. With this configuration, when the refrigerant temperature Te is higher than the outdoor air dew point Td, the ventilation system does not operate to supply air, preventing the condensation water from being reduced by dry outdoor air, thereby maintaining odor removal efficiency.

[0060] (Technology 4) An air conditioning apparatus according to any one of Technology 1 to Technology 3, characterized in that it is provided with an indoor temperature and humidity detection sensor that measures the temperature Tin and humidity Hin of indoor air, and an outdoor temperature and humidity detection sensor that measures the temperature Tout and humidity Hout of outdoor air, and when Tout is higher than Tin, the control unit operates the ventilation device to supply air. When the indoor air temperature Tin is low, the temperature range in which cooling operation is possible becomes narrower, making it difficult to condense condensation. With this configuration, air supply operation can be limited to when Tout is higher than Tin, and air supply operation is performed only when an increase in condensation water due to the intake of outdoor air is expected, thereby achieving the effect of increasing the efficiency of odor removal.

[0061] (Technical 5) The air conditioner according to any one of Technical 1 to Technical 4, characterized in that when Hin becomes equal to or less than a predetermined value, the control unit performs air supply operation using the ventilation device. When the indoor air temperature Tin is low, the temperature range in which cooling operation is possible narrows, making it difficult to condense condensation. With this configuration, air supply operation is limited to when Tout is higher than Tin, and air supply operation is performed only when an increase in condensation due to the intake of outdoor air is expected, thereby achieving the effect of increasing the efficiency of odor removal.

[0062] (Technology 6) A control method for an air conditioner in which a control unit controls an outdoor unit equipped with a ventilation device that ventilates indoor air and an indoor unit equipped with an electrostatic atomizer inside a housing, wherein the control unit executes an odor component removal mode in which the ventilation device performs air supply operation and dehumidification operation using the indoor heat exchanger while the electrostatic atomizer generates electrostatic mist. This configuration decomposes and removes odorous components using electrostatic mist, and also increases the amount of condensed water by supplying moist outdoor air, effectively removing odorous components. As a result, odors in the room can be reduced. [Industrial Applicability]
