[Technical field]
[0001] An embodiment of the present invention relates to an air conditioning apparatus. [Background technology]
[0002] Conventionally, air conditioners composed of an indoor unit and an outdoor unit are known. Some air conditioners are equipped with a human detection sensor that detects whether or not a person is present in an indoor area (room, indoors) where the indoor unit is installed, and have a function of reflecting the detection result in air supply control. For example, some air conditioners are equipped with a function of automatically executing control to purify the indoor unit itself or control to purify the air in the indoor area when it is detected that no human is present in the indoor area using an infrared sensor as the human detection sensor. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2008-224132 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, the detection results of the infrared sensor are easily affected by the room temperature, sunlight conditions, etc., and there are cases where it is not possible to accurately detect a human being present in the room. As a result, there are cases where it is not possible to appropriately control the air conditioning device.
[0005] One example of a problem to be solved by the present invention is to provide an air conditioner that can more accurately detect a detection target present in an indoor area and more appropriately control the air blown into the indoor area. [Means for solving the problem]
[0006] An air conditioning apparatus according to one embodiment of the present invention comprises a housing, a fan, a radar, and a control unit. The housing is provided with an internal ventilation passage, an intake port that connects the ventilation passage to the outside, and an exhaust port that connects the ventilation passage to the outside. The fan is provided in the ventilation passage and blows air from the intake port to the exhaust port. The radar is provided in the housing and detects the presence or absence of a detection target present in an indoor area in which the housing is installed, the number of detection targets, and shape information of the detection targets. News At least Also check The control unit determines a control manner of the wind blown out from the outlet by the fan based on a detection result of the radar. Then, when the detection target regarded as a living body is detected in the indoor area based on the detection result, the control unit assigns an identifier to each living body and tracks the living body once detected, and, in accordance with the assignment of the identifier, classifies the living body into at least a first class detection target which is the highest classification, a second class detection target which is shorter than the first class detection target, and a third class detection target which is the lowest classification, according to the height of the living body from the floor surface based on the shape information, and maintains the classification even when the shape information changes due to a change in the posture of the living body, and determines a control mode of the air blown out from the air outlet based on the classification. .
[0008] In addition, based on the detection result, when a living body is not detected in the indoor area, the control unit may execute absent air purification control in which clean air for purifying the air in the indoor area is blown out from the outlet at a larger airflow rate than when a living body is detected in the indoor area.
[0009] In addition, the control unit may be configured to execute a first air purification control to blow purified air from the outlet to purify the air in the indoor area when a predetermined number or more of the living organisms are detected in the indoor area based on the detection result.
[0010] In addition, the control unit may be configured to execute a second air purification control in which, when the third class detection object is detected in the indoor area based on the detection result, purified air for purifying the air in the indoor area is blown out from the outlet.
[0011] The control unit may also be configured to blow out the clean air toward an absence area, where no living body is present, within the indoor area based on the detection result.
[0012] The control unit may also obtain an amount of activity of the living body present in the indoor area based on the detection result, and determine the amount of clean air to be blown out based on the amount of activity.
[0013] In addition, the air conditioning apparatus of the embodiment may be equipped with at least one air deflector that can be moved between a first closed position that covers at least a portion of the air outlet and a first open position that opens at least a portion of the air outlet, and at least one ventilation member that can be positioned in a second closed position that covers at least a portion of the air outlet opened by the air deflector positioned in the first open position, has an inner surface facing the ventilation passage in the second closed position and an outer surface facing the outside in the second closed position, and is provided with at least one ventilation port that opens to the inner surface and the outer surface, and can form a first air outlet flow path in the second closed position where air blown by the fan passes through the ventilation port and is discharged to the outside, and a second air outlet flow path adjacent to the first air outlet flow path where air is discharged to the outside without passing through the ventilation port. Then, based on the detection result, when the living body is detected in the indoor area, the control unit may determine the direction in which the mixed air that has passed through the first blowing flow path and the second blowing flow path is blown out based on the position where the living body is present.
[0014] Furthermore, when the third class detection target is detected, the control unit may blow out the wind toward a position that is a predetermined distance away from a position where the third class detection target is present.
[0015] Furthermore, the control unit may change the volume of the airflow to a current set value or less when the third class detectable object is detected.
[0016] The air conditioning apparatus of the embodiment may further include a temperature detection unit that detects the temperature of the indoor area, and a heat exchanger provided in the ventilation duct. When the living body is detected in the indoor area based on the detection result and the temperature of the indoor area is outside a predetermined range, the control unit may determine a heat exchange mode of the heat exchanger and a control mode of the air blown out from the air outlet so that the temperature of the indoor area falls within the predetermined range.
[0018] Furthermore, when the control unit loses sight of the detection target being tracked, the control unit may continue, for a predetermined period of time, the wind control mode that was in effect immediately before the detection target was lost.
[0019] According to the above air conditioning device, for example, the presence or absence of a detection target in the indoor area, the number of detection targets, and shape information of the detection targets are detected by a radar. of At least Also check In addition, radar can detect the distance to a target when acquiring information on the presence, number, shape, etc. of the target. Tracking By doing so, the behavior (movement history) of the detection target can be detected. Do As a result, the detection target in the indoor area Against Appropriate airflow control can be performed. [Brief description of the drawings]

[0021] Hereinafter, an embodiment of an air conditioning device according to the present disclosure will be described with reference to the drawings. In this specification, components according to the embodiment and descriptions of the components may be described in multiple ways. The components and their descriptions are merely examples and are not limited by the expressions in this specification. The components may also be identified by names different from those in this specification. Furthermore, the components may also be described by expressions different from those in this specification.
[0022] FIG. 1 is an illustrative schematic block diagram showing the general configuration of an air conditioner 1 according to an embodiment, which is composed of an indoor unit 10 and an outdoor unit 100. As shown in FIG.
[0023] The indoor unit 10 of the air conditioning device 1 of this embodiment is equipped with a radar 2, and detects a detection target present in the indoor area in which the indoor unit 10 is installed. In this embodiment, the detection target particularly includes a living body CR (adult, child, infant, pet, etc.), as well as furniture (chair, sofa, bed, etc.) and walls that the living body CR can use. In other words, the radar 2 can also detect the size (indoor area) and volume of the room in which the indoor unit 10 is installed.
[0024] In this embodiment, the air conditioning device 1 (indoor unit 10) acquires information on the presence or absence of living organisms CR among the detection targets detected by the radar 2, the number of living organisms CR (number of people, number of individuals), and shape information of the living organisms CR (characteristic information, for example, size (height), etc.), and determines a control mode to provide wind (conditioned air) suitable for the living organisms CR present in the indoor area. For example, based on the detection result of the radar 2, the control unit of the indoor unit 10 (indoor unit control unit 80 described later) can regard (determine) the detection target as a "living organism CR" if the detection target moves. If the detection target enters the room, the indoor unit 10 (radar 2) recognizes the detection target as a living organism CR by detecting the entry movement, and reflects this in the control of the indoor unit 10. Furthermore, even if the detection target does not move (the detection position does not change) in the indoor area (room), if the detection target moves, for example, if the detection target detects the movement movement of the detection target or the behavior of a part of the detection target, the indoor unit 10 (radar 2) recognizes the detection target as a living organism CR and reflects this in the control of the indoor unit 10. On the other hand, the indoor unit 10 (radar 2) regards objects that remain continuously stationary (for example, furniture, walls, etc.) as non-living objects, and excludes them from the objects reflected in the control of the indoor unit 10. The determination of whether or not it is a living CR is not limited to this, and the shape or pulsation of the detection object may be detected. In addition, other sensors, for example, an infrared sensor, etc. may be provided, and the determination of whether or not it is a living CR may be performed in conjunction with the detection result.
[0025] The indoor unit 10 includes an operation terminal 94a. The operation terminal 94a receives an operation instruction from a living CR present in the indoor area, and transmits a command to the indoor unit 10 in response to the received operation instruction. The living CR is, for example, a person. The operation terminal 94a is, for example, a remote controller. The operation terminal 94a may also be a smartphone or the like that operates with a dedicated application.
[0026] In addition to the radar 2, the indoor unit 10 has an indoor unit control unit 80, an up / down air deflector 25, and a left / right air deflector 29. The indoor unit control unit 80 performs air conditioning processing in response to commands received from the operation terminal 94a, and performs control in response to a living body CR detected using the radar 2. The indoor unit 10 has a "radar control mode" which is a substantially automatic control based on the detection result by the radar 2, and a "normal control mode" in which the user controls (sets) the indoor unit 10 without using the radar 2 through operation using the operation terminal 94a. As will be described later, the indoor unit 10 classifies detection objects that can be considered as living bodies CR into at least a first class detection object (e.g., an adult) which is the highest classification, a second class detection object (e.g., a child) which is lower than the first class detection object, and a third class detection object (e.g., an infant, a ped, a sleeping living body, etc.) which is the lowest classification, according to the height from the floor surface (height in the Z direction, i.e., height), for example, at the timing of entering the room or immediately thereafter. Then, control is performed to appropriately blow air onto the living body CR of the third category detection target, which is particularly difficult for the living body CR to appropriately operate the operation terminal 94a by itself.
[0027] In the "radar control mode", the radar 2 continuously or intermittently detects the position of each classification of detection targets (living organisms CR) indoors under the control of the indoor unit control unit 80. The indoor unit control unit 80 tracks the position of the detected living organism CR, and controls the up / down air deflectors 25, the left / right air deflectors 29, the ventilation members 26, etc. to blow air toward the living organism CR or, conversely, toward a position that avoids the living organism CR, according to the type of living organism CR detected. The indoor unit control unit 80 controls the direction of the air (conditioned air) blown out from the indoor unit 10 by controlling the operation of the up / down air deflectors 25 and the left / right air deflectors 29.
[0028] This allows the way in which conditioned air is blown out from the indoor unit 10 to be dynamically changed in response to the movement of the living organism CR present in the view area, thereby dynamically improving the comfort of the living organism CR present in the indoor area.
[0029] Specifically, the indoor unit 10 performs air conditioning processing on air drawn in from the indoor area through the air inlet, and blows out the conditioned air that has been subjected to the air conditioning processing toward the indoor area. The air conditioning processing includes, for example, heat absorption processing (cooling), heating processing (heating), dehumidification processing, humidification processing, air blowing processing, and air cleaning processing. The heat absorption processing, heating processing, dehumidification processing, humidification processing, air blowing processing, and air cleaning processing correspond to the cooling operation mode, heating operation mode, dehumidification operation mode, humidification operation mode, air blowing operation mode, and air cleaning operation mode, which are the operation modes (main operation modes) of the air conditioner 1, respectively.
[0030] The main operation mode can be appropriately combined with the control modes (radar control mode, normal control mode). In the radar control mode, the air conditioner 1 (indoor unit 10) can be in any of the cooling operation mode, heating operation mode, dehumidification operation mode, humidification operation mode, fan operation mode, and air purification operation mode. The same applies to the normal control mode.
[0031] In the air conditioning process, the humidification process may be omitted. In this case, as an operation mode of the air conditioner 1, the humidification operation mode may be omitted.
[0032] The indoor unit 10 has an auxiliary operation mode in which, when blowing out conditioned air, winds of two different flow speeds are mixed to generate turbulence that diffuses over a wide area, making the discharged wind an overall gentle wind flow (so-called windless (registered trademark) wind). The auxiliary operation mode can be appropriately combined with the control modes (radar control mode, normal control mode) and can be appropriately combined with the main operation mode.
[0033] The indoor unit 10 may have an automatic operation mode as an operation mode. The indoor unit 10 detects the temperature of the indoor area with a room temperature sensor 3 (temperature detection unit). In the automatic operation mode, the indoor unit 10 (indoor unit control unit 80) may operate in a heating operation mode if the detected temperature is higher than a set temperature, and may operate in the heating operation mode if the detected temperature is lower than the set temperature.
[0034] The air purification process is performed, for example, by an ion emission method that releases ions into the air, an ultraviolet irradiation method that irradiates the inside of the indoor unit 10 with ultraviolet rays to sterilize, and a dust collection method that collects dust when air in the indoor area is sucked into the indoor unit 10. Dust collection methods include, for example, a filter dust collection method and an electric dust collection method. In the filter dust collection method, air is passed through a fine filter such as a HEPA filter, and dirt such as dust is filtered by the filter and removed from the air. In the electric dust collection method, dirt such as dust contained in the sucked air is charged by high-voltage discharge and adsorbed to a dust collection unit (for example, the heat exchanger 22 or a filter charged with the opposite polarity) and collected. The dirt adsorbed to the heat exchanger 22 can be automatically discharged outdoors together with the condensed water that has condensed on the surface of the heat exchanger, for example.
[0035] As shown in Fig. 1, in the air conditioner 1, the indoor unit 10 includes a radar 2, an indoor unit control unit 80, a room temperature sensor 3, a heat exchanger 22, a fan 23, a filter 24 (described later), up-down air deflectors 25, left-right air deflectors 29, ventilation members 26, a receiving device 94, and the like. The indoor unit 10 also includes a first control circuit 81, a second control circuit 82, a third control circuit 83, a phon motor 84, an up-down air deflector motor 85, a left-right air deflector motor 86, a switching motor 87, and the like, all of which are controlled by the indoor unit control unit 80. In the case of the configuration shown in Fig. 1, an example is shown in which an air purification unit 4 that performs an electric dust collection method as an air purification process is controlled by the indoor unit control unit 80.
[0036] The outdoor unit 100 also includes a heat exchanger 122, a fan 123, a four-way valve 124, a compressor 125, an outdoor unit control unit 180, a fourth drive circuit 181, a fifth drive circuit 182, a sixth drive circuit 183, a fan motor 184, a valve switching motor 185, a compressor motor 186, etc.
[0037] In the indoor unit 10, the fan 23 is disposed near the heat exchanger 22. The fan 23 guides air drawn from the indoor area through the air inlet of the indoor unit 10 to the heat exchanger 22, and also guides the conditioned air that has been heat exchanged in the heat exchanger 22 to the air outlet of the indoor unit 10. The indoor unit control unit 80 drives the fan motor 84 with the first control circuit 81 to rotate the fan 23 around the rotation axis. The indoor unit control unit 80 is capable of changing the rotation speed of the fan 23.
[0038] The heat exchanger 22 has, for example, a refrigerant pipe (refrigerant circuit) and a plurality of fins. The heat exchanger 22 is in thermal contact with the refrigerant circuit passing nearby. The heat exchanger 22 exchanges heat between the refrigerant and the air drawn in from inside the room.
[0039] In the outdoor unit 100, the fan 123 is disposed near the heat exchanger 122. The fan 123 rotates in response to control by the outdoor unit control unit 180. As a result, the fan 123 draws in outside air and guides it to the heat exchanger 122, and also discharges the outside air that has been heat exchanged in the heat exchanger 122 to the outside of the outdoor unit 100. The outdoor unit control unit 180 drives the fan motor 184 using a fourth drive circuit 181, causing the fan 123 to rotate around its axis of rotation. The indoor unit control unit 80 is able to change the rotation speed of the fan 123 via the outdoor unit control unit 180.
[0040] The heat exchanger 122 has, for example, a refrigerant pipe (refrigerant circuit) and a plurality of fins. The heat exchanger 122 is in thermal contact with the refrigerant circuit passing nearby. The heat exchanger 122 exchanges heat between the refrigerant and the outside air.
[0041] The four-way valve 124 is disposed in the refrigerant circuit. The four-way valve 124 can switch the flow path of the refrigerant in the refrigerant circuit between the cooling side and the heating side according to the control by the outdoor unit control unit 180. The outdoor unit control unit 180 drives a valve switching motor 185 by a fifth drive circuit 182, and can switch the four-way valve 124 between the cooling side and the heating side. The indoor unit control unit 80 can switch the four-way valve 124 between the cooling side and the heating side via the outdoor unit control unit 180.
[0042] The compressor 125 is disposed in the refrigerant circuit. The compressor 125 compresses the refrigerant by the outdoor unit control unit 180 under the control of the indoor unit control unit 80, and sends the refrigerant into the refrigerant circuit. The outdoor unit control unit 180 drives the compressor motor 186 by a sixth drive circuit 183, and causes the compressor 125 to perform a cycle operation of compressing the refrigerant. The indoor unit control unit 80 can change the number of cycles of the compressor 125 (the number of compression cycles performed per unit time) via the outdoor unit control unit 180.
[0043] For example, in the air conditioning device 1, the indoor unit control unit 80 and the outdoor unit control unit 180 switch the four-way valve 124 to the cooling side in the cooling operation mode. Then, a heat absorption process is performed in the heat exchanger 22, heat is absorbed from the air in the indoor region by the refrigerant, and the conditioned air with the absorbed heat is blown out to the indoor region. Then, a heat dissipation process is performed in the heat exchanger 122, and the heat absorbed by the refrigerant is released to the outside air.
[0044] Alternatively, the air conditioner 1 switches the four-way valve 124 to the heating side in the heating operation mode by the indoor unit control unit 80 and the outdoor unit control unit 180. Then, a heat absorption process is performed in the heat exchanger 122, and heat is absorbed from the outside air by the refrigerant. Then, a heating process is performed in the heat exchanger 22, the air in the indoor region is heated with the heat absorbed by the refrigerant, and the heated conditioned air is blown out into the indoor region.
[0045] The vertical air deflectors 25 and the horizontal air deflectors 29 each adjust the direction of the conditioned air blown into the indoor area. Air direction means the direction of the wind. In this specification, the indoor unit control unit 80 directly controls the direction of the vertical air deflectors 25 and the horizontal air deflectors 29, but the direction of the vertical air deflectors 25 and the horizontal air deflectors 29 is treated as roughly the same as the direction of the wind (wind direction) immediately after it is blown out from the air outlet of the indoor unit 10. In other words, the vertical air deflectors 25 and the horizontal air deflectors 29 can adjust the wind direction by their orientation, and the indoor unit control unit 80 can control the wind direction by controlling the orientation of the vertical air deflectors 25 and the horizontal air deflectors 29. Note that the orientation of the vertical air deflectors 25 and the horizontal air deflectors 29 can be controlled individually. This allows air to be blown out in one direction from the entire air outlet of the indoor unit 10, and allows two or more air streams with different directions to be blown out from two or more areas of the air outlet of the indoor unit 10 partitioned by upper and lower air deflectors 25, left and right air deflectors 29, etc.
[0046] The up / down air deflector 25 can be switched between a closed position and an open position. When switched to the closed position, the up / down air deflector 25 blocks the air outlet. When switched to the open position, the up / down air deflector 25 opens the air outlet. When the air outlet is opened by the operation of the up / down air deflector 25, the up / down air deflector 25 and the left / right air deflector 29 adjust the direction of the conditioned air blown into the indoor area. The up / down air deflector 25 adjusts the direction of the conditioned air in the vertical direction. The left / right air deflector 29 adjusts the direction of the conditioned air in the horizontal direction.
[0047] The structure of the indoor unit 10 will be described in more detail with reference to Figures 2 to 7. Figure 2 is an illustrative and schematic cross-sectional view showing the configuration of the indoor unit 10.
[0048] As described above, the indoor unit 10 has the heat exchanger 22, the fan 23, the filter 24, the two up-down airflow direction vanes 25 (25A, 25B), a plurality of left-right airflow direction vanes 29 (see Figs. 1 and 4), the ventilation members 26, etc. inside the housing 21. The up-down airflow direction vanes 25, the left-right airflow direction vanes 29, and the ventilation members 26 may also be referred to as louvers.
[0049] As shown in each drawing from FIG. 2 onwards, in this specification, for convenience, an X-axis, a Y-axis and a Z-axis are defined. The X-axis, the Y-axis and the Z-axis are perpendicular to each other. The X-axis is provided along the width of the indoor unit 10. The Y-axis is provided along the depth of the indoor unit 10. The Z-axis is provided along the height of the indoor unit 10.
[0050] Furthermore, in this specification, an X direction, a Y direction, and a Z direction are defined. The X direction is a direction along the X axis, and includes a +X direction indicated by an arrow on the X axis, and a -X direction opposite to the arrow on the X axis. The Y direction is a direction along the Y axis, and includes a +Y direction indicated by an arrow on the Y axis, and a -Y direction opposite to the arrow on the Y axis. The Z direction is a direction along the Z axis, and includes a +Z direction indicated by an arrow on the Z axis, and a -Z direction opposite to the arrow on the Z axis. In this embodiment, the +Z direction is the upward direction, and the -Z direction is the downward direction.
[0051] The housing 21 is formed in a substantially rectangular parallelepiped shape extending in the X direction. The housing 21 may be formed in other shapes. The housing 21 is hung, for example, on a wall of a building (indoors). The housing 21 has an upper surface 21a and a lower surface 21b. The upper surface 21a is provided at or near the upper end of the housing 21 and faces substantially upward. The lower surface 21b is provided at or near the lower end of the housing 21 and faces substantially downward.
[0052] The housing 21 is provided with an air passage 31, an inlet 32, and an outlet 33. The air passage 31 is provided inside the housing 21. The inlet 32 opens, for example, to the upper surface 21a of the housing 21. The outlet 33 opens, for example, to the lower surface 21b of the housing 21. The inlet 32 and the outlet 33 may open to other parts of the housing 21.
[0053] The indoor unit 10 can pass wind through the ventilation passage 31. Wind is a flow of gas such as air. The intake port 32 is provided at one end of the ventilation passage 31, and connects the ventilation passage 31 to the outside of the indoor unit 10. The outlet port 33 is provided at the other end of the ventilation passage 31, and connects the ventilation passage 31 to the outside of the indoor unit 10. In other words, the ventilation passage 31 is provided inside the housing 21, between the intake port 32 and the outlet port 33.
[0054] Heat exchanger 22 is provided in ventilation passage 31. Heat exchanger 22 exchanges heat with the surrounding gas in ventilation passage 31. As a result, heat exchanger 22 cools the air flowing through ventilation passage 31 during cooling operation, and heats the air flowing through ventilation passage 31 during heating operation.
[0055] Fan 23 is provided in ventilation passage 31. Fan 23 rotates around rotation axis Axf extending in the X direction to send air from inlet 32 to outlet 33 in ventilation passage 31. As a result, indoor unit 11 draws indoor air from inlet 32 into ventilation passage 31 and blows out air (wind) in ventilation passage 31 from outlet 33. For this reason, in this specification, the side of ventilation passage 31 closer to inlet 32 is referred to as the upstream side, and the side closer to outlet 33 is referred to as the downstream side.
[0056] The fan 23 is located downstream of the heat exchanger 22. Therefore, when the fan 23 generates air, the air sucked in from the air inlet 32 passes through the fins of the heat exchanger 22. As a result, the air flowing through the ventilation passage 31 exchanges heat with the heat exchanger 22.
[0057] Filter 24 is provided at suction port 32 or near suction port 32 in ventilation passage 31. Filter 24 is located upstream of heat exchanger 22. Filter 24 covers suction port 32 from inside housing 21. Filter 24, for example, filters air sucked in from suction port 32 and captures dust in the air. As described above, by configuring filter 24 with a HEPA filter or the like, higher quality air purification processing can be achieved.
[0058] The vertical airflow direction vanes 25 and the horizontal airflow direction vanes 29 can be configured as shown in Figs. 2 to 4. Fig. 2 shows the vertical airflow vanes 25 in a closed position Pc1 (sometimes referred to as a first closed position). Fig. 3 is a cross-sectional view showing the configuration and operation of the indoor unit 10, showing the vertical airflow vanes 25 in an open position Po1 (sometimes referred to as a first open position). Fig. 4 is a perspective view showing the configuration and operation of the indoor unit 10, showing the vertical airflow vanes 25 in an open position and the horizontal airflow vanes 29 visible.
[0059] The vertical airflow direction vane 25 may include a plurality of vertical airflow direction vanes 25A, 25B. The vertical airflow direction vanes 25A, 25B are members that adjust the wind direction of the conditioned air in the vertical direction, and are also called vertical louvers. The vertical airflow direction vane 25A forms a first flow path C1 of the conditioned air, and the vertical airflow direction vane 25B forms a second flow path C2 of the conditioned air. The vertical airflow direction vanes 25A, 25B each have an axis portion 41 and a plate portion 42.
[0060] The shaft portion 41 is formed in a generally cylindrical shape extending in the X direction. The shaft portion 41 is supported by the housing 21 so as to be rotatable around a rotation axis Axl extending in the X direction. Each of the upper and lower louvers 25A and 25B has its own rotation axis Axl. The plate portion 42 protrudes from the shaft portion 41 in a direction generally perpendicular to the rotation axis Axl. The plate portion 42 is formed in a generally rectangular plate shape extending in the X direction.
[0061] The vertical air deflector 25A is supported by a rotating shaft Axl, and the vertical air deflector motor 85 is controlled by the second control circuit 82, so that it can move between a closed position Pc1 shown in Fig. 2 and an open position Po1 shown in Fig. 3. The vertical air deflector 25B is supported by a rotating shaft Axl, and the vertical air deflector motor 85 is controlled by the second control circuit 82, so that it can move between a closed position Pc1 shown in Fig. 2 and an open position Po1 shown in Fig. 3.
[0062] 2, when the vertical airflow direction vane 25A is switched to the closed position Pc1, it closes the air outlet 33 which is the outlet of the first flow path C1. When the vertical airflow direction vane 25B is switched to the closed position Pc1, it closes the air outlet 33 which is the outlet of the second flow path C2. The first flow path C1 and the second flow path C2 form the air outlet 33 of the indoor unit 10.
[0063] 3 and 4, the vertical airflow direction flare 25A opens the first flow path C1 when switched to the open position Po1. The vertical airflow direction flare 25B opens the second flow path C2 when switched to the open position Po1.
[0064] The open position Po1 includes various positions where the vertical airflow direction vanes 25A, 25B open a part of the air outlet 33. For example, the open position Po1 includes a position where the vertical airflow direction vanes 25A, 25B face substantially horizontally, a position where the vertical airflow direction vanes 25A, 25B face downward, and a plurality of positions between these two positions, as shown in Fig. 3. That is, the vertical airflow direction vanes 25A, 25B can rotate between a position where they face substantially horizontally and a position where they face downward.
[0065] The vertical airflow direction flap 25A, 25B located at the open position Po1 adjusts the vertical direction (+Z direction, -Z direction) of the airflow discharged from the air outlet 33 depending on the orientation of the vertical airflow direction flap 25A, 25B. That is, as shown in Fig. 3, when the vertical airflow direction flap 25A, 25B faces substantially horizontally, the indoor unit 10 discharges airflow substantially horizontally. On the other hand, when the vertical airflow direction flap 25A, 25B faces downward, the indoor unit 10 discharges airflow downward.
[0066] As shown in FIG. 4, the left / right air deflector 29 is supported by a rotation axis Ax2 (not shown) extending in the X direction, and the left / right air deflector motor 86 is controlled by the second control circuit 82, so that the left / right air deflector 29 can move between a rotation position toward the -X end and a rotation position toward the +X end.
[0067] The left and right airflow direction vanes 29 may include multiple left and right airflow vanes 29-1 to 29-k, 29-(k+1) to 29-2k. The multiple left and right airflow vanes 29-1 to 29-k, 29-(k+1) to 29-2k are members that adjust the wind direction of the conditioned air in the left and right directions (-X direction, +X direction), respectively, and are also called left and right louvers. Note that the directions of the left and right airflow vanes 29-1 to 29-k on the -X side and the left and right airflow vanes 29-(k+1) to 29-2k on the +X side may be independently controllable by the indoor unit control unit 80.
[0068] The left and right air deflectors 29-1 to 29-k on the -X side may be connected to a common rotating shaft Ax2 (not shown), and the left and right air deflectors motor 86 may be controlled by the second control circuit 82, so that they can move together between the open position at the -X side end and the open position at the +X side end. The left and right air deflectors 29-(k+1) to 29-2k on the +X side may be connected to a common rotating shaft Ax2 (not shown), and the left and right air deflector motor 86 may be controlled by the second control circuit 82, so that they can move together between the open position at the -X side end and the open position at the +X side end.
[0069] The ventilation member 26 shown in FIG. 2 can be switched between a closed position Pc2 (sometimes referred to as a second closed position) and an open position Po2 (sometimes referred to as a second open position). The ventilation member 26 can be arranged in the closed position Pc2, which covers at least a part of the outlet 33 (first flow path C1) opened by the vertical airflow direction vane 25A located at the open position Po1. The ventilation member 26 has an inner surface facing the ventilation passage 31 in the closed position Pc2 and an outer surface facing the outside in the closed position Pc2, and is provided with at least one ventilation port 56 that opens on the inner surface and the outer surface. In the closed position Pc2, the ventilation member 26 can form a first outlet flow path (first flow path C1) through which the wind sent by the fan 23 is discharged to the outside through the ventilation port 56, and a second outlet flow path (second flow path C2) adjacent to the first outlet flow path (first flow path C1) through which the wind is discharged to the outside without passing through the ventilation port 56. That is, when the ventilation member 26 is switched to the closed position Pc2, it is inserted into a part of the flow path of the conditioned air blown into the room, thereby changing the opening ratio of that part of the flow path.
[0070] When the ventilation member 26 is switched to the open position Po2, it is released from a portion of the flow path (for example, retracted from a portion of the flow path), and the opening ratio of the portion of the flow path is returned to the original value.
[0071] In the air conditioner 1, when the no-wind mode is set as the auxiliary operation mode, the indoor unit control unit 80 switches the ventilation member 26 to the closed position Pc2. When the ventilation member 26 is switched to the closed position Pc2, it is selectively inserted into the first flow path C1 to change the opening ratio of the first flow path C1. Meanwhile, the opening ratio of the second flow path C2, which is opened and closed by the vertical air direction vanes 25B where the ventilation member 26 is not present, is maintained as it was. When the no-wind mode is set as the auxiliary operation mode, the indoor unit control unit 80 switches the ventilation member 26 to the open position Po2. When the ventilation member 26 is switched to the open position Po2, it is retreated from the first flow path C1, and the opening ratio of the first flow path C1 is returned to the original.
[0072] For example, ventilation member 26 can be opened and closed between an open position Po2 shown in Fig. 3 and a closed position Pc2 shown in Fig. 5. Fig. 6 is a perspective view showing the configuration of ventilation member 26.
[0073] 3, when the ventilation member 26 is switched to the open position Po2, it is accommodated in a recess 21c of the housing 21 provided near the air outlet 33. The recess 21c is recessed from an inner surface 21d of the housing 21 that forms part of the ventilation passage 31. When the ventilation member 26 is located at the open position Po2, being accommodated in the recess 21c prevents the ventilation member 26 from obstructing the wind flowing through the first flow path C1.
[0074] As shown in FIG. 5, the ventilation member 26 is inserted into the first flow path C1 in a state switched to the closed position Pc2, and changes the aperture ratio of the first flow path C1. The aperture ratio of the first flow path C1 becomes smaller than that before the ventilation member 26 is inserted. As shown in FIG. 6, the ventilation member 26 is a member in which a plurality of ventilation holes 56 are arranged on a plate-shaped plate portion 52. The ventilation member 26 is supported by a shaft portion 51, and the switching motor 87 is controlled by the third control circuit 83, and the ventilation member 26 is movable between the closed position Pc2 and the open position Po2. When the ventilation member 26 is moved to the closed position Pc2, as shown in FIG. 7, the wind moving in the ventilation passage 31 by the fan 23 passes through the ventilation holes 56 and changes to wind W2a.
[0075] On the other hand, the ventilation member 26 is not provided in the outlet 33 forming the second flow path C2. The opening ratio of the second flow path C2 is maintained as it is. In other words, the wind discharged from the second flow path C2 becomes wind W1a (laminar flow) that does not pass through the ventilation member 26. As a result, the wind W2a passing through the ventilation member 26 provided in the first flow path C1 and the wind W1a passing through the second flow path C2 where the ventilation member 26 is not provided are formed adjacent to each other.
[0076] In this case, the flow speed of the wind W2a increases as the opening ratio of the first flow path C1 decreases. Therefore, the wind W2a draws in the wind W1a. As a result, the wind W1a hits the wind W2a. The wind W2a that has transitioned to a turbulent flow diffuses and hits the wind W1a flowing adjacent to the wind W2a. In this way, the winds W1a and W2a, which have different flow speeds and states (laminar flow or turbulent flow), flow next to each other and hit each other. That is, the wind W1a that does not pass through the ventilation member 26 (ventilation opening 56) and the wind W2a that has passed through the ventilation member 26 (ventilation opening 56) interfere with each other.
[0077] When the wind W1a and the wind W2a collide with each other, for example, the masses of the wind W1a and the wind W2a are broken, and the wind W2a, which is a turbulent flow, is carried by the wind W1a. The wind W1a and the wind W2a generate such various interactions to generate a turbulent flow Ws (mixed wind) that diffuses over a wide area. As a result, the turbulent flow Ws discharged from the indoor unit 10 becomes closer to a natural wind (so-called wind without a windy feeling) than the wind immediately after being discharged from the air outlet 33. In this case, the ventilation member 26 only needs to be formed in either the first flow path C1 or the second flow path C2, which can contribute to suppressing an increase in the number of parts, a complication of the configuration of the indoor unit 10, and an increase in costs. In addition, the ventilation member 26 has a simple structure equipped with only the ventilation port 56, which can contribute to suppressing an increase in costs and a decrease in the strength of the ventilation member 26.
[0078] Returning to FIG. 1, the radar 2 can detect the position, moving speed, angle, and shape (height from the floor surface, etc.) of a detection target (e.g., a living body CR) in a room. The radar 2 is a Doppler radar such as an ultrasonic radar, a millimeter wave radar, a microwave radar, or a lidar. The radar 2 has a transmitting unit 2a, a receiving unit 2b, and a signal processing unit 2c. The radar 2 generates radio waves, sound waves, and light such as millimeter waves and microwaves in the signal processing unit 2c and transmits them from the transmitting unit 2a to the indoor area, and receives reflected waves reflected by a detection target (living body CR) that may be present in the indoor area in the receiving unit 2b and passes them to the signal processing unit 2c. The radar 2 is provided at any position on the front surface of the housing 21 of the indoor unit 10, but it is preferable to provide the radar 2 at a position that makes it easy to detect the position of the detection target (living body CR) in the indoor area. The radar 2 may be embedded in a position near the center in the X direction in the +Y side part of the housing 21, as shown by dotted lines in FIG. 2 to FIG. 5. It is preferable that the transmitting unit 2a and the receiving unit 2b are exposed from the surface of the housing 21, as shown in Fig. 4. The detection process by the radar 2 will be described in detail later.
[0079] FIG. 8 is an illustrative schematic block diagram showing details of the indoor unit control section 80 of the indoor unit 10 (air conditioner 1) configured as above.
[0080] The CPU constituting the indoor unit control unit 80 reads out a control program installed and stored in a non-volatile storage device such as a ROM, and realizes a module that executes various controls and calculation processes according to the program. The indoor unit control unit 80 includes modules such as an operation mode control unit 80a, a drive circuit control unit 80b, a radar control unit 80c, a human body detection unit 80d, a classification unit 80e, an air purification control unit 80f, a wind control unit 80g, and a temperature monitoring unit 80h. The human body detection unit 80d includes detailed modules such as a number of people detection unit 80d1, a tracking unit 80d2, and an activity amount measurement unit 80d3. Each of these modules may be configured as hardware. Each module may also be integrated or divided according to function.
[0081] The operation mode control section 80a switches between the "radar control mode" and "normal control mode" described above as the operation modes of the indoor unit 10, and switches between the cooling operation mode, heating operation mode, dehumidification operation mode, humidification operation mode, ventilation operation mode, air purification operation mode, etc. These switching operations are performed based on a command signal from the operation terminal 94a operated by the user, or automatically based on the detection results of the radar 2.
[0082] The drive circuit control unit 80b controls the first control circuit 81, the second control circuit 82, and the third control circuit 83 based on the operation mode switched by the operation mode control unit 80a and the classification, number, and activity level of the living organisms CR included in the detection targets present in the indoor area, and controls the operation of the fan 23, the upper and lower air deflectors 25, the left and right air deflectors 29, and the ventilation member 26.
[0083] The radar control unit 80c controls transmission and reception of the radar 2 (transmitter 2a, receiver 2b) and also controls the signal processor 2c to obtain analysis results (detection results) of the transmitted waves and received waves. The radar 2 may enable detection processing after the indoor unit 10 is started up by operation of the operation terminal 94a, or may be kept in standby mode at all times regardless of the start-up of the indoor unit 10, and may be normally started up to obtain the presence or absence of a detection target, the number of detection targets, shape information of the detection target, etc., when it detects movement (motion) of an object (detection target) in an initially set indoor area.
[0084] Based on the analysis result of the radar control unit 80c, the human body detection unit 80d identifies a living body CR from among the detection targets, and assigns an ID (identifier) to each identified living body, which is stored in a storage unit (not shown). The human body detection unit 80d regards a detection target that has newly entered a preset indoor area, that is, a moving body, as a living body CR, assigns an ID to the living body CR at the time of entering the indoor area or immediately after, and thereafter maintains and monitors the ID until the detection target is lost (for example, when the moving body leaves the indoor area or enters a blind spot area that may exist in the indoor area) and a predetermined period of time has passed. The storage unit may be, for example, a volatile storage device or the like.
[0085] The number of people detection unit 80d1 counts valid IDs present in the indoor area, detects the number of living organisms CRs (number of people) staying in the indoor area, and stores it in the storage unit.
[0086] The tracking unit 80d2 tracks a valid ID present in the indoor area and stores it in the storage unit. As described above, when an ID is assigned to a detection target when the detection target enters the indoor area or immediately after the detection target enters the indoor area, the tracking unit 80d2 performs a tracking process continuously for each ID thereafter. When a detection target (living body CR, ID) being tracked enters a blind spot and is lost, the ID may be maintained for a predetermined period (e.g., 30 minutes, etc.) and the same ID may be made valid when the detection target appears from the same blind spot. In this case, the indoor unit control unit 80 may continue the air control mode immediately before the valid ID is lost. A new ID may be assigned to a detection target (living body CR) that appears from a blind spot after a predetermined period has elapsed. When a detection target (living body CR) to which an ID is assigned leaves the indoor area through an entrance (room entrance), the ID may be invalidated.
[0087] The activity amount measuring unit 80d3 measures the amount of activity (amount of exercise) based on the amount of movement and the moving speed of each detection target (living body CR) tracked by the tracking unit 80d2, and stores the amount of activity in the storage unit. The amount of activity can be, for example, an index of the amount of dust in an indoor area. Therefore, for example, the ease of dust generation may change depending on the size of the detection target (living body CR). Therefore, for example, the weighting of the amount of activity may be different between adults and children, and reflected in the air cleaning process, etc.
[0088] As shown in FIG. 9, the classification unit 80e classifies detection targets that can be considered as living bodies CR in the detection area E of the radar 2 (the transmission area of the transmission unit 2a) into groups according to, for example, height (height from the floor surface). In the case of the radar 2 mounted on the indoor unit 10, the position of the entrance / exit of the indoor area R (room), the floor surface, the wall surface, etc. can be recognized at the time of initial setting, etc. Therefore, for example, the height from the floor surface (height in the Z direction, i.e., height) can also be detected at the timing when the detection target enters from the entrance / exit or immediately thereafter. As described above, when a newly detected detection target moves, the number of people detection unit 80d1 can consider it as a living body CR. The classification unit 80e classifies the detection targets that are considered as living bodies CR into at least a first type detection target, a second type detection target, and a third type detection target based on their size (height). This classification is stored in a storage unit (not shown) or the like in association with an ID given by the human body detection unit 80d, for example.
[0089] As shown in FIG. 9, the first detection target is classified as the highest height, and may be classified as the first group (height range A1) of Mm or more, and the living body CR may be regarded as an adult living body CR1. The second detection target is classified as the second group (height range A2) of heights lower than the first detection target (for example, less than Mm, more than Nm), and the living body CR may be regarded as a child living body CR2. The third detection target is classified as the third group (height range A3) of heights lower than the first detection target (for example, less than Nm: M>N), and the living body CR (CR3) may be regarded as an infant living body CR3a, a ped living body CR3b, a sleeping living body CR3c, or the like. Note that this classification (living bodies CR1 to CR3) is an example, and may be classified as four or more. Note that the above-mentioned classification heights are an example, and may be appropriately changed according to the living body CR (user, pet, etc.) that uses the room in which the indoor unit 10 is installed by the user of the indoor unit 10.
[0090] As described above, the radar 2 can track the detection target from the beginning when it enters the indoor area R. Usually, a user (a living body CR that is a detection target) enters the indoor area R (room) in a standing state. The radar 2 assigns an ID to the detection target at the time of its entry into the indoor area R or immediately thereafter, and the classification unit 80e classifies the detection target, for example, in a standing state, and the tracking unit 80d2 tracks the detection target while maintaining the ID and classification. In other words, even if a detection target (living body CR) that was initially classified as a first-class detection target sits on a sofa or the like after entering the indoor area R and its apparent height (posture: standing posture, sitting posture, lying posture, etc.) changes, the classification unit 80e does not change the classification to a second-class detection target or a third-class detection target.
[0091] The air purification control unit 80f controls whether or not to perform air purification processing in the indoor area R, the efficiency of air purification, etc., depending on the detection status of the living body CR in the indoor area R. The air purification control unit 80f controls the air purification unit 4, and performs air control processing, for example, using an electric dust collection method. As described above, the air purification unit 4 is equipped with a high-voltage discharge unit and the like to charge contaminants such as dust contained in the air sucked in from the suction port 32. In this case, the air purification control unit 80f controls the fan motor 84 via the first control circuit 81 to adjust the strength of the fan 23, thereby adjusting the amount of air sucked in from the suction port 32 and adjusting the air purification efficiency.
[0092] For example, as shown in FIG. 10, the air purification control unit 80f may execute the air purification process for the indoor area R when the human body detection unit 80d does not detect a living body CR even when the detection process is performed in the detection area E of the radar 2 in the indoor area R. FIG. 10 shows a case where the radar 2 of the indoor unit 10 detects only a sofa CRS as a still object as a detection target. In this case, the air purification control unit 80f executes "absent air purification control" in which clean air (clean air from which dust and the like has been removed by the function of the air purification unit 4) for purifying the air in the indoor area R is blown out from the outlet 33 at a larger volume than when a living body CR is detected in the indoor area R. As described above, the efficiency of the air control process is largely determined by the amount of air sucked in and the amount of air blown out. Therefore, when an efficient air control process is to be executed, the driving sound of the fan 23 tends to become louder. Therefore, by executing the absent air purification control during the period when the living body CR is absent, an efficient air purification process can be executed without giving the user discomfort due to the driving sound. When unattended air cleaning control is performed, temperature adjustment (heating or cooling) of the air to be blown out is not necessary, so the heat exchange process by the heat exchanger 22 may be omitted. Unattended air cleaning control may be performed continuously when a living organism CR is absent, but in that case, it would be performed continuously at night or when the occupant is absent, which is not economical. Therefore, the execution period may be set by operating the operation terminal 94a, etc. When entry of a living organism CR into the indoor area R is confirmed during execution of unattended air cleaning control, the air cleaning control unit 80f may reduce the rotation speed of the fan 23 to a value lower than that during execution of unattended air cleaning control, and may return to a normal air cleaning state in which quietness is prioritized over air cleaning efficiency.
[0093] On the other hand, as shown in FIG. 11, the air purification control unit 80f may execute a first air purification control for executing an air purification process for the indoor region R when a predetermined number or more of living bodies CR are detected by the human body detection unit 80d in the case where a detection process is performed in the detection area E of the radar 2 in the indoor region R. In the case of FIG. 11, a living body CR11 (adult), a living body CR12 (adult), a living body CR2 (child), and a living body CR13 (adult) are detected in the indoor region R, for example, indicating a "closed state." In this way, when a predetermined number or more (for example, four or more) of living bodies CR are confirmed in the indoor region R, the air purification control unit 80f may automatically execute the first air control regardless of the presence or absence of a user request (operation of the operation terminal 94a). As a result, the air condition can be automatically improved even in a situation where dust is easily stirred up (easily rises) or odor is easily generated due to the presence of multiple living bodies CR, and a more comfortable environment can be provided. In this case, it is possible to reduce the driving noise of the fan 23 compared to the above-mentioned unattended air cleaning control, so that the user (living CR) is less likely to perceive the driving noise due to the execution of the air cleaning process. Of course, the driving force of the fan 23 may be increased at the request of the user (living CR) to increase the air cleaning efficiency. In this case, the heat exchange process may be executed by the heat exchanger 22 at the request of the user (living CR), and the heating process or the cooling process may be executed together with the air cleaning process. When multiple living CRs are detected in the indoor area R, the human body detection unit 80d may form a group consisting of multiple living CRs, and the wind control unit 80g may control the wind direction for each group.
[0094] In addition, as shown in FIG. 12, when the detection process is performed in the detection area E of the radar 2 in the indoor area R, if the human body detection unit 80d detects a third-class detection target (such as an infant CR3a or a sleeping living body CR3c) as a living body CR, the air purification control unit 80f executes a second air purification control for executing an air purification process for the indoor area R. In the case of FIG. 12, a sleeping living body CR3c (regardless of adult, child, infant, etc.) and an infant CR3a are illustrated as the third-class detection target in the indoor area R. In this case, when an infant CR3a or a sleeping living body CR3c is present, the air purification control unit 80f automatically executes an air purification process to provide a more comfortable environment, for example, based on the idea that it is preferable that the air in the indoor area R has a high degree of cleanliness. In this case, since the movement of the living body CR is small and dust is often difficult to fly up, it is desirable to execute a quiet air purification control that prioritizes low noise (quietness) by reducing the driving force of the fan 23 and reducing the driving sound. Furthermore, the radar 2 can detect the behavior of, for example, a living organism CR3c in a sleeping state. Therefore, the air purification control unit 80f may, for example, prioritize quietness and reduce the driving force of the fan 23 when only a sleeping living organism CR3c is detected and the living organism CR3c is deemed to be in a light sleep with tossing and movement of arms and legs, and may execute control to improve the air purification efficiency when the living organism CR3c is deemed to be in a deep sleep with no tossing or movement of arms and legs for a predetermined period. In this case, it is effective when the sleeping living organism CR3c is an infant (including a baby, etc.) because the air environment in the indoor area R is further improved.
[0095] The airflow control unit 80g controls the direction and quality of the air (for example, cooling airflow or heating airflow) blown out from the air outlet 33 according to the presence of a detection target (living body CR) in the indoor area R detectable by the radar 2. The airflow control unit 80g controls the vertical airflow vane motor 85 via the second control circuit 82 to control the left-right position of the vertical airflow vane 25. The airflow control unit 80g also controls the left-right airflow vane motor 86 via the left-right airflow vane motor 86 to control the left-right position of the left-right airflow vane 29. The airflow control unit 80g can appropriately change the direction (arrival position) of the air blown out from the air outlet 33 by combining the direction control of the vertical airflow vane 25 and the left-right airflow vane 29. For example, the airflow control unit 80g controls the vertical airflow vane 25 and the left-right airflow vane 29 so that the air always hits the living body CR tracked by the tracking unit 80d2, thereby improving the feeling of coolness during cooling control, for example. Conversely, the wind control unit 80g can find a position where the living body CR is not present (absence area) and control the up / down air deflectors 25 and the left / right air deflectors 29 so that the living body CR tracked by the tracking unit 80d2 is not exposed to the wind, thereby reducing the discomfort caused by the wind directly hitting the living body CR. The wind control unit 80g may periodically change the direction of the wind to alternate between a state where the living body CR is exposed to the wind and a state where the living body is not exposed to the wind.
[0096] For example, as shown in FIG. 12, there are cases where the sleeping environment can be improved by not blowing the wind directly on the sleeping living body CR3c. In such a case, the wind control unit 80g controls the up-down airflow vane 25 and the left-right airflow vane 29 so that the reach area WE of the wind blown out from the air outlet 33 is, for example, a position in front of the sleeping living body CR3c. For example, the wind is blown out toward a position a predetermined distance (for example, 1 m) away from the position where the third-class detection object is present. In particular, when the sleeping living body CR3c is an infant (including a baby), it is easier to prevent the living body CR3c from becoming too cold or too dry by not blowing the wind directly on the sleeping living body CR3c. The direction in which the wind is blown out may be shifted in the left-right direction (X direction) or the depth direction (Y direction) around the position of the third-class detection object as the center. It may also be shifted in the up-down direction (Z direction). In the up-down direction, the wind may be blown toward the ceiling surface. In addition, when the living body CR detected by the human body detection unit 80d is a moving infant CR3a or a ped CR3b, the tracking results of the tracking unit 80d2 are utilized to adjust the direction and arrival position of the wind so that the wind is directed toward a position where the infant CR3a or the ped CR3b is not present, thereby making it easier to prevent the wind from blowing directly on the infant CR3a or the ped CR3b and to prevent the infant CR3a or the ped CR3b from becoming too cold or too dry.
[0097] In addition, when the human body detection unit 80d detects a third class detection target CR3 (such as a small child CR3a, a pet CR3b, or a sleeping living body CR3c) as a living body CR, the airflow control unit 80g may change the airflow volume to a current set value or less. In the case of the indoor unit 10 of this embodiment, the volume of air (airflow volume, wind power) blown out from the air outlet 33 may be determined (set) by the user's operation of the operation terminal 94a, or may be automatically set according to the temperature of the indoor area R according to the operation mode. Also, as described above, in the case of the indoor unit 10 of this embodiment, the airflow volume may be set according to the state of the indoor area R based on the type and number of living bodies CR detected by the radar 2. Therefore, before the third class detection target CR3 is detected, there may be cases where air that is too strong (too much) for the third class detection target CR3 is blown out from the air outlet 33. Therefore, when the third class detection target CR3 is detected, the airflow control unit 80g may change the airflow volume to a current set value or less. In other words, by weakening the airflow, it is possible to provide an environment more suitable for the third category detection target CR3, which is thought to require careful consideration of how the air is blown.
[0098] In addition, when the temperature of the indoor area R is close to the set temperature when the third-class detection target CR3 is detected, the air volume may already be controlled to be sufficiently weak. In that case, the change in the set value of the air volume due to the discovery of the third-class detection target CR3 may be set to "0". In other words, the actual change in the air volume may not be performed. In addition, the change in the set value of the air volume due to the discovery of the third-class detection target CR3 may be applied even when the above-mentioned windless wind is generated, and an environment more suitable for the third-class detection target CR3 can be provided. In addition, when the air volume is changed to a value lower than the current set value, for example, it may be changed to a predetermined set value, for example, "weak", or it may be changed to be gradually weakened depending on the temperature of the indoor area R and the type and number of other living organisms CR present.
[0099] As described above, the wind control unit 80g controls the switching motor 87 via the third control circuit 83 to move the ventilation member 26 to the closed position Pc2, and can blow out turbulent air (so-called wind without wind) from the outlet 33. The wind control unit 80g controls the ventilation member 26 as well as the up-down air deflector 25 and the left-right air deflector 29 to control the direction of the wind without wind, for example, in the direction where the living body CR is present or in the direction where the living body is not present. For example, by blowing wind without wind (i.e., natural wind) onto the living body CR, it is possible to improve the feeling of freshness while suppressing the discomfort caused by the cold air during cooling control, and to make it easier to feel warmth while suppressing the discomfort caused by the warm air during heating control. Conversely, blowing out wind without wind in the direction where the living body CR is not present can further suppress the wind from blowing directly onto the living body CR. In addition, even when blowing out a wind of countless winds, it is possible to blow out a wind of calm toward a position where a moving living body CR is present or toward a position where the living body CR is not present, by utilizing the tracking result of the tracking unit 80d2. When an infant CR3a (especially a baby) is present in the indoor area R, the wind of calm is effective in terms of managing the physical condition of the infant CR3a.
[0100] In addition, the wind control unit 80g may control the fan motor 84 via the first control circuit 81 according to the amount of activity acquired by the activity amount measuring unit 80d3 to adjust the output of the fan 23, that is, the amount of airflow (amount of airflow). For example, as shown in FIG. 13, the tracking unit 80d2 can track the movement trajectory L1 of the living body CR11, the movement trajectory L2 of the living body CR12, the movement trajectory L3 of the living body CR13, and the like, so that the activity amount measuring unit 80d3 tallies a score determined by the movement distance and movement speed of the target living body CR. Then, the wind control unit 80g may control the wind power during air cleaning processing, windless control, heating control, cooling control, and the like, based on the score. In other words, by adjusting the amount of airflow according to the amount of activity, a more comfortable environment in the indoor area R can be maintained. In particular, when the amount of activity of the living body CR is high, the frequency of dust and odor generation in the indoor area R increases, so a more comfortable environment can be provided by changing the air cleaning efficiency according to the amount of activity.
[0101] The temperature monitoring unit 80h controls the operation mode control unit 80a based on the temperature (room temperature) of the indoor area R provided by the room temperature sensor 3 (temperature detection unit), and executes at least cooling control (control of the heat exchange mode) regardless of the operation of the operation terminal 94a. For example, when the radar 2 detects a living body CR in the indoor area R and the temperature monitoring unit 80h detects that the indoor temperature is out of a predetermined temperature, for example, when it reaches 32°C or higher, the indoor unit 10 starts cooling control regardless of the operation of the operation terminal 94a. For example, even if the living body CR is a child CR2, a toddler CR3a, a ped CR3b, etc. and is unable to judge an appropriate room temperature or operate the operation terminal 94a, or even if an adult living body CR1 is unable to judge an appropriate room temperature or operate the operation terminal 94a due to illness, the temperature of the indoor area R (room) can be appropriately maintained. In particular, automatic cooling control is effective in preventing heatstroke, etc. (reducing the burden on the living body CR). In addition, when a living body CR is detected and the room temperature becomes equal to or higher than a predetermined temperature, the temperature monitoring unit 80h cooperates with the airflow control unit 80g to blow air toward the detected living body CR for a predetermined time from the start of cooling control, thereby efficiently lowering the body temperature, and after the predetermined period has elapsed, the airflow direction may be changed to a direction where the living body CR is not present or may be switched to windless control. In this case, the temperature burden on the living body CR can be effectively reduced, and after it is considered that the burden on the living body CR has been reduced, it becomes easier to provide a more comfortable environment in the indoor area R for the living body CR.
[0102] The temperature monitoring unit 80h may be configured to automatically execute heating control (control of the heat exchange mode) when the room temperature falls below a predetermined temperature. In this case, as with the cooling control, it is possible to automatically maintain a comfortable room temperature.
[0103] In the above description, when the tracking unit 80d2 loses sight of the detection target being tracked within the indoor area R, it maintains the ID for a predetermined period of time, and when the target leaves the entrance / exit, it invalidates the ID. In this case, the operation mode control unit 80a may stop the control (e.g., cooling control, heating control, etc.) that has been performed up to that point. In another embodiment, after detecting a detection target (living body CR) to which an ID should be assigned within the indoor area R, the operation mode control unit 80a may continue the control (e.g., cooling control, heating control, etc.) performed when the living body CR to which the ID was assigned was present for a predetermined period of time (e.g., several hours) until a control end instruction is issued by the operation terminal 94a, even if the living body CR to which the ID was assigned is lost. In other words, when the indoor unit control unit 80 loses sight of the detection target being tracked, it may continue the control mode of the wind immediately before the target was lost for a predetermined period of time. As a result, it is possible to prevent the air conditioning control from being stopped when the living body CR temporarily leaves the indoor area R or enters a blind spot of the detection area E of the radar 2 within the indoor area R and the detection target is temporarily lost.
[0104] Thus, according to the air conditioning device 1 (indoor unit 10) of this embodiment, the radar 2 can detect at least one of the presence or absence of a detection target (e.g., living organisms CR) in the indoor area R, the number of detection targets, and shape information of the detection targets. When acquiring the presence or absence, number, shape information, etc. of the detection targets, it is possible to detect the distance to the detection target, and by continuously detecting the detection target, it is possible to detect the behavior (movement history) of the detection target. As a result, it is possible to control the blowing of air appropriate to the detection target present in the indoor area R.
[0105] FIG. 14 is an exemplary and schematic cross-sectional view showing another configuration for generating wind with a windless feeling. In the case of the indoor unit 10 shown in FIG. 14, a ventilation member 26 (26A, 26B) is arranged for each air outlet 33. FIG. 15 is an exemplary and schematic view showing the configuration of the ventilation member 26 (26A, 26B), and is a front view showing the ventilation member 26A arranged in the first flow path C1 and the ventilation member 26B arranged in the second flow path C2. Note that the configurations of the ventilation member 26A and the ventilation member 26B are substantially the same, and when there is no need to distinguish between them, they will be described as the ventilation member 26. In addition, the configuration of the indoor unit 10 shown in FIG. 14 is substantially the same as the configuration shown in FIG. 5, except that the ventilation member 26 is arranged at each air outlet 33, and members having the same functions are given the same reference numerals, and their description is omitted or simplified.
[0106] For example, the ventilation member 26A is located near the upper end of the first flow path C1, similar to the configuration shown in Fig. 5. The ventilation member 26B is located at the upper end of the second flow path C2 in the Z direction. Note that the ventilation member 26A may close the first flow path C1 in the closed position Pc2, and the ventilation member 26B may close the second flow path C2 in the closed position Pc2, and is not limited to the example of Fig. 14.
[0107] The ventilation member 26A located at the closed position Pc2 covers the first flow path C1 opened by the vertical air direction flap 25A located at the open position Po1. The ventilation member 26B located at the closed position Pc2 covers the second flow path C2 opened by the vertical air direction flap 25B located at the open position Po1.
[0108] It should be noted that the two ventilation members 26 positioned at the closed position Pc2 do not need to completely block the air outlet 33. For example, the air outlet 33 may be connected to the room without being covered by the ventilation members 26 in the X direction, or the air may be able to pass through a gap between the ventilation members 26 and the upper and lower air direction vanes 25. For example, when viewed in the air flow direction, it is sufficient that most of the first flow path C1 and the second flow path C2 are covered by the ventilation members 26A and 26B.
[0109] The ventilation member 26 positioned at the open position Po2 opens a part of the air outlet 33 opened by the vertical air direction flap 25 positioned at the open position Po1. In the case of Fig. 14, the ventilation member 26A positioned at the open position Po2 opens the first flow path C1 opened by the vertical air direction flap 25A positioned at the open position Po1. The ventilation member 26B positioned at the open position Po2 opens the second flow path C2 opened by the vertical air direction flap 25B positioned at the open position Po1.
[0110] The ventilation members 26 are made of, for example, synthetic resin, similar to the ventilation member 26 shown in Fig. 6. The ventilation members 26 may be made of other materials such as metal. Each of the two ventilation members 26 has a shaft portion 51 and a plate portion 52.
[0111] The shaft portion 51 is formed in a substantially cylindrical shape extending in the X direction. The shaft portion 51 is supported by the housing 21 so as to be rotatable about a rotation axis Axc extending in the X direction. Each of the multiple ventilation members 26 has its own rotation axis Axc. The plate portion 52 protrudes from the shaft portion 51 in a direction substantially perpendicular to the rotation axis Axc. The plate portion 52 is formed in a substantially rectangular plate shape extending in the X direction. By rotating the shaft portion 51 about the rotation axis Axc, the ventilation members 26 can move between a closed position Pc2 and an open position Po2.
[0112] The shaft portion 51 of the ventilation member 26 is spaced upward from the plate portion 42 of the vertical airflow direction flare 25 located in the open position Po1. The plate portion 52 of the ventilation member 26 located in the closed position Pc2 extends from the shaft portion 51 toward the plate portion 42 of the vertical airflow direction flare 25.
[0113] The tip 52a of the plate portion 52 of the ventilation member 26 located at the closed position Pc2 abuts against the plate portion 42 of the vertical air direction flap 25 or is located near the plate portion 42. As a result, the ventilation member 26 located at the closed position Pc2 covers a part of the outlet 33 opened by the vertical air direction flap 25 located at the open position Po1. The tip 52a is an end of the plate portion 52 located on the opposite side to the shaft portion 51.
[0114] The length of the plate portion 52 in the X direction is approximately equal to the length of the outlet 33 in the X direction. This allows the ventilation members 26A, 26B located in the closed position Pc2 to cover most of the first flow path C1 and the second flow path C2.
[0115] The length of the plate portion 52 in the direction in which the plate portion 52 protrudes from the shaft portion 51 is shorter than the maximum lengths of the first flow path C1 and the second flow path C2 in the Z direction. This prevents the ventilation member 26 from interfering with the vertical airflow direction flap 25 when moving between the closed position Pc2 and the open position Po2.
[0116] The plate portion 52 has an inner surface 52b and an outer surface 52c. The inner surface 52b faces the ventilation passage 31 in the closed position Pc2. The outer surface 52c is located on the opposite side to the inner surface 52b. The outer surface 52c faces the outside of the indoor unit 10 in the closed position Pc2.
[0117] When both ventilation members 26 are located at the open position Po2, the two ventilation members 26 open almost the entire area of the air outlet 33 opened by the vertical air direction flap 25 located at the open position Po1. Note that even if the two ventilation members 26 are located at the open position Po2, when the vertical air direction flap 25 is located at the closed position Pc1, the first flow path C1 and the second flow path C2 are covered by the corresponding vertical air direction flap 25.
[0118] 14, ventilation member 26A located at open position Po2 is accommodated in recess 21c of housing 21 provided near air outlet 33. Recess 21c is recessed from inner surface 21d of housing 21 forming part of ventilation passage 31. By being accommodated in recess 21c, ventilation member 26A located at open position Po2 is prevented from obstructing the wind flowing through ventilation passage 31.
[0119] The ventilation member 26B is provided in the ventilation passage 31 near the air outlet 33. The plate portion 52 of the ventilation member 26B located in the open position Po2 extends in a direction along the flow of air in the ventilation passage 31. This prevents the ventilation member 26B located in the open position Po2 from obstructing the air flowing through the ventilation passage 31. Note that the arrangement of the ventilation members 26A, 26B located in the open position Po2 is not limited to the above example.
[0120] 15, a plurality of first ventilation openings 55 and a plurality of second ventilation openings 56a are provided in each of the ventilation members 26. Note that each of the ventilation members 26 may be provided with a row of the first ventilation openings 55 and a row of the second ventilation openings 56a.
[0121] 15, the multiple first ventilation holes 55 and the multiple second ventilation holes 56a are through holes penetrating the plate portion 52. Therefore, the multiple first ventilation holes 55 and the multiple second ventilation holes 56a open to the inner surface 52b and the outer surface 52c of the plate portion 52, respectively.
[0122] The multiple first ventilation openings 55 and the multiple second ventilation openings 56a are alternately arranged in the arrangement direction Dp. Therefore, the first ventilation openings 55 and the second ventilation openings 56a are provided side by side in the arrangement direction Dp. The arrangement direction Dp is an example of a first direction, and is a direction along the outer surface 52c of the plate portion 52.
[0123] The arrangement direction Dp is approximately equal to the direction in which the plate portion 52 extends from the shaft portion 51. When the ventilation member 26 is located at the closed position Pc2, the arrangement direction Dp is approximately equal to the Z direction. Note that the arrangement direction Dp is not limited to this example and may be another direction such as the X direction.
[0124] 15, the first ventilation opening 55 is, for example, a substantially rectangular slit extending in the X direction. The X direction is an example of a second direction, and is a direction that runs along the outer surface 52c of the plate portion 52 and intersects with the arrangement direction Dp. The first ventilation opening 55 may be a hole having a cross section that is circular, rectangular, triangular, or of another shape. The multiple first ventilation openings 55 are arranged in the arrangement direction Dp.
[0125] The second ventilation hole 56a is a hole having a circular cross section, similar to the example shown in Fig. 6. The second ventilation hole 56a may be a hole having a rectangular, triangular, or other shaped cross section. The cross sections of the first ventilation hole 55 and the second ventilation hole 56a are cross sections perpendicular to the direction in which the first ventilation hole 55 and the second ventilation hole 56a penetrate the plate portion 52.
[0126] The second ventilation openings 56a are arranged in the X direction. In other words, the second ventilation openings 56a are arranged at intervals from one another in the X direction. Therefore, the second ventilation openings 56a form rows 58 of the second ventilation openings 56a arranged in the X direction. In the plate portion 52, the rows 58 are arranged in the arrangement direction Dp. The second ventilation openings 56a may be arranged in a lattice pattern or a staggered pattern.
[0127] A plurality of slit-shaped first ventilation openings 55 and a row 58 of second ventilation openings 56a are alternately arranged in the arrangement direction Dp. Therefore, the plurality of first ventilation openings 55 and the plurality of second ventilation openings 56a form a row 59 of the first ventilation openings 55 and the second ventilation openings 56a aligned in the arrangement direction Dp.
[0128] The first ventilation openings 55 are arranged at both ends of a row 59 of the first ventilation openings 55 and the second ventilation openings 56a aligned in the arrangement direction Dp. Therefore, in the arrangement direction Dp, the second ventilation openings 56a are located between two of the first ventilation openings 55. Note that in the ventilation member 26 of the modified example, the second ventilation opening 56a may be arranged at an end of the row 59 of the first ventilation openings 55 and the second ventilation openings 56a aligned in the arrangement direction Dp. In this case, the first ventilation openings 55 are located between two of the second ventilation openings 56a in the arrangement direction Dp.
[0129] As shown in FIG. 15, the cross section of each of the second ventilation openings 56a is smaller than the cross section of each of the first ventilation openings 55. The total cross section of the second ventilation openings 56a included in each of the rows 58 is smaller than the cross section of one of the first ventilation openings 55. As a result, the flow speed of the wind (W2a) passing through the second ventilation openings 56a is faster than the flow speed of the wind (W1a) passing through the first ventilation opening 55. As a result, the wind passing through the ventilation member 26A (26B) exhibits the same behavior as the example described in FIG. 7. That is, the wind W2a draws in the wind W1a. As a result, the wind W1a hits the wind W2a. In addition, the wind W2a that has transitioned to a turbulent flow is diffused and hits the wind W1a flowing adjacent to the wind W2a. In this way, the wind W1a and the wind W2a, which have different flow speeds and states (laminar flow or turbulent flow), hit each other by flowing next to each other. That is, the wind W1a that does not pass through the ventilation member 26 (second ventilation opening 56a) and the wind W2a that has passed through the ventilation member 26 (second ventilation opening 56a) interfere with each other.
[0130] When the wind W1a and the wind W2a collide with each other, for example, the masses of the wind W1a and the wind W2a are broken up, and the wind W2a, which is a turbulent flow, is carried by the wind W1a. The wind W1a and the wind W2a generate such various interactions to generate a turbulent flow Ws that diffuses over a wide range. As a result, the turbulent flow Ws discharged from the indoor unit 10 can be made closer to a natural wind (so-called wind without a windy feeling) than the wind immediately after being discharged from the air outlet 33.
[0131] In this manner, even if a ventilation member 26A is provided in the first flow path C1 and a ventilation member 26B is provided in the second flow path C2, it is possible to generate a wind that feels like there is no wind, similar to the case where a ventilation member 26 is provided only in the first flow path C1 as shown in Figure 5, etc., and similar control using the detection results of the radar 2 and similar effects can be obtained.
[0132] In the above embodiment, for example, a residential air conditioner 1 has been described as an example, but the configuration of this embodiment can be similarly applied to various types of air conditioners 1. For example, the configuration of this embodiment can also be applied to commercial (store, etc.) air conditioners, and similar effects can be obtained.
[0133] Although the embodiment of the present invention has been described above, the above embodiment is merely an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. The above embodiment is included in the scope and gist of the invention, and is included in the scope of the invention and its equivalents described in the claims. [Explanation of symbols]
