JP2019-086160

In the conventional technology, when a plurality of people are in a room who have different desired modes of wind blown out from an air conditioner, it is not possible to send air in a mode that matches the preferences of the plurality of people.

An example of the problem to be solved by the present invention is to obtain an air conditioner with a novel configuration that can simultaneously send different types of wind into a room.

An air conditioner according to an embodiment of the present invention includes a housing, a plurality of ventilation members, a plurality of first wind direction plates, and one second wind direction plate . The housing is provided with an outlet that blows out conditioned air into the room. The plurality of ventilation members are arranged in the width direction of the air outlet, and each can be switched between an open position where the air outlet is opened and a closed position where a part of the air outlet is closed. The plurality of first wind direction plates are capable of changing the direction of the air blown into the room, and each of the plurality of first wind direction plates is capable of changing the wind direction of the air blown into the room, and is configured to connect the air outlet with two arranged vertically in an in-plane direction perpendicular to the width direction of the air outlet. It is divided into two branch channels and arranged in the width direction corresponding to the plurality of ventilation members. The second wind direction plate is arranged with the plurality of first wind direction plates, and forms the lower branch flow path of the two branch flow paths between the plurality of first wind direction plates, and The lower branch channel can be opened and closed. Each of the plurality of ventilation members has a plurality of ventilation ports opened therein, and the closed positions of the plurality of ventilation members are aligned in an in-plane direction perpendicular to the width direction of the air outlet. The ventilation member is provided in the upper branch channel of the two branch channels. A state in which the ventilation member is switched to the closed position so as to block the upper branch channel and air can be blown out without blocking the lower branch channel, and a state in which the ventilation member is switched to the open position. Each ventilation member can be set to a state in which air can be blown out without blocking the two branch channels. When at least one of the plurality of ventilation members moves to the closed position and closes the upper branch channel, the second wind direction plate is in a state where the lower branch channel is opened.

In the air conditioner, for example, the first wind direction plate can change the wind direction by swinging. When the first wind direction plate corresponding to the ventilation member swings, the ventilation member moves to a position where it does not interfere with the first wind direction plate.

In the air conditioner, for example, the plurality of first wind direction plates swing so that they are in the same phase.

In the air conditioner, for example, the plurality of first wind direction plates swing so as to be out of phase with each other.

In the air conditioner, for example , the second wind direction plate can change the direction of the air blown into the room by swinging . The second wind direction plate does not swing when the first wind direction board swings.

In the air conditioner, for example , the second wind direction plate can change the direction of the air blown into the room by swinging . The second wind direction plate swings in the same phase as the swing of the first wind direction board.

According to the above air conditioner, different types of wind can be sent indoors at the same time.

FIG. 1 is an exemplary and schematic block diagram showing a schematic configuration of an air conditioner 1 according to an embodiment that includes an indoor unit 10 and an outdoor unit 100.

The air conditioner 1 includes an operating terminal 94a, an indoor unit 10, and an outdoor unit 100. The indoor unit 10 is placed indoors, and the outdoor unit 100 is placed outdoors. The operating terminal 94a receives an operating instruction from a living body CR existing indoors, and transmits an instruction to the indoor unit 10 in accordance with the accepted operating instruction. The living body CR is, for example, a human being, a pet, or the like. The operation terminal 94a is, for example, a remote controller. Note that the operating terminal 94a may be a smartphone or the like that operates with a dedicated application.

The indoor unit 10 of the air conditioner 1 of this embodiment includes a radar 2 and detects a detection target present in the room where the indoor unit 10 is installed. In this embodiment, the detection target includes not only the living body CR but also furniture (chairs, sofas, beds, etc.) and walls that can be used by the living body CR. That is, the radar 2 can also detect the size (indoor), volume, etc. of the room in which the indoor unit 10 is installed. The living body CR is a human being, a pet, etc. Radar 2 is an example of a biological sensor. Note that the biological sensor is not limited to the radar 2.

In the present embodiment, the air conditioner 1 (indoor unit 10) acquires information particularly regarding biological CR among the detection targets detected by the radar 2, and generates wind (conditioned air) suitable for the biological CR existing indoors. The control mode is determined so as to provide the following information. 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 consider (determine) that the detection target is a “biological CR” when the detection target moves. . When the object to be detected enters the room, the indoor unit 10 (radar 2) recognizes it as a living body CR by detecting the movement of the object to be detected, and causes the recognition to be reflected in the control of the indoor unit 10. In addition, the indoor unit 10 (radar 2) detects the movement of the detection target, for example, when the detection target moves, even if the detection target does not move indoors (room) (there is no change in the detection position). If a behavior of a part of the object to be detected is detected, it is recognized as a biological CR and is reflected in the control of the indoor unit 10. On the other hand, the indoor unit 10 (radar 2) considers objects that remain stationary (for example, furniture, walls, etc.) to be non-living objects, and excludes them from being subject to control by the indoor unit 10. Note that the determination of whether or not it is a biological CR is not limited to this, and may also detect the shape, pulsation, etc. of the detection target. Further, other sensors such as an infrared sensor may be provided, and the detection result may be used to determine whether or not it is a biological CR.

In addition to the radar 2, the indoor unit 10 includes an indoor unit control section 80, a vertical wind direction plate 25, a left and right wind direction plate 29, and room temperature sensors 3A and 3B. The room temperature sensor 3A detects, for example, the temperature of the air near the suction port 32 of the indoor unit 10. The indoor unit control section 80 controls each section so that, for example, the temperature detected by the room temperature sensor 3A becomes a set temperature. Further, the room temperature sensor 3B detects the indoor temperature (temperature distribution) and the temperature (temperature distribution) of the walls of the room. Room temperature sensor 3B is, for example, an infrared sensor. The indoor unit control section 80 controls the direction of air blown out from the indoor unit 10, for example, based on the detection result of the room temperature sensor 3B. The indoor unit control section 80 performs air conditioning processing according to a command received from the operating terminal 94a, and also performs control according to the biological CR detected using the radar 2. The indoor unit 10 can be controlled in a "radar control mode" which is essentially automatic control based on the detection results by the radar 2, and in a "radar control mode" which is essentially automatic control based on the detection results by the radar 2, and in which the indoor unit 10 is controlled without using the radar 2 when the user operates using the operation terminal 94a. (setting) "normal control mode".

In the "radar control mode", the radar 2 continuously or intermittently detects the position of the detection target (biological CR) indoors under the control of the indoor unit control section 80. The indoor unit control unit 80 tracks the position of the detected living body CR and controls the vertical wind direction plate 25, the left and right wind direction plate 29, so as to send wind toward the living body CR or conversely to a position avoiding the living body CR. Controls the ventilation member 26 and the like. The indoor unit control section 80 controls the direction of the wind (conditioned air) blown out from the indoor unit 10 by controlling the operation of the vertical wind direction plate 25 and the left and right wind direction plates 29.

As a result, the way the conditioned air is blown out from the indoor unit 10 can be dynamically changed according to the movement of the biological CR existing within the detection area, so the comfort of the biological CR existing indoors can be dynamically changed. can be improved.

Specifically, the indoor unit 10 performs air conditioning processing on the air sucked in from the room through the suction port, and blows out the conditioned air that has been subjected to the air conditioning processing toward the room. The air conditioning process includes, for example, endothermic treatment (cooling), heat treatment (heating), dehumidification treatment, humidification treatment, ventilation treatment, air cleaning treatment, and the like. Endothermic treatment, heating treatment, dehumidification treatment, humidification treatment, ventilation treatment, and air purification treatment are respectively performed in cooling operation mode, heating operation mode, dehumidification operation mode, and humidification as the operation modes (main operation modes) of the air conditioner 1. Compatible with driving mode, ventilation driving mode, and air purifying driving mode.

Note that the main operation mode can be combined with a control mode (radar control mode, normal control mode) as appropriate. In the radar control mode, the air conditioner 1 (indoor unit 10) can take any of the cooling operation mode, heating operation mode, dehumidification operation mode, humidification operation mode, ventilation operation mode, and air purification operation mode. Note that in the radar control mode, the driving modes that can be combined are not limited to those described above, and other driving modes can also be combined. The same applies to the normal control mode.

In the air conditioning process, the humidification process may be omitted. At this time, the humidification operation mode may be omitted as the operation mode of the air conditioner 1.

In the auxiliary operation mode, the indoor unit 10 generates a turbulent flow that spreads over a wide range by mixing two types of wind speeds when blowing out conditioned air, and transforms the emitted wind into a gentle wind flow ( It has a calm mode that creates a so-called calm wind (registered trademark). The auxiliary operation mode can be appropriately combined with a control mode (radar control mode, normal control mode), and can be appropriately combined with the main operation mode.

The indoor unit 10 may have an automatic operation mode as an operation mode. The indoor unit 10 detects indoor and wall temperatures using a room temperature sensor 3A. In the automatic operation mode, the indoor unit 10 (indoor unit control unit 80) operates in the heating operation mode if the detected temperature is higher than the set temperature, and operates in the heating operation mode if the detected temperature is lower than the set temperature. It's okay.

The air cleaning process includes, for example, 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 bacteria, and a method that removes bacteria when indoor air is sucked into the indoor unit 10. This is performed using a dust collection method that collects dust. Note that the dust collection method includes, 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-mesh filter such as a HEPA filter, and dirt substances such as dust are filtered out by the filter to be removed from the air. In the electrostatic precipitator method, dirt substances such as dust contained in the air that is inhaled are charged with a high-pressure discharge, and then captured by being adsorbed to a dust collection unit (for example, a heat exchanger 22 or a filter charged to the opposite polarity). collect. Note that the dirt substances adsorbed on the heat exchanger 22 can be automatically discharged outdoors together with, for example, when dew condensation water that has condensed on the surface of the heat exchanger is discharged.

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), and a vertical wind direction. It includes a plate 25, a left and right wind direction plate 29, a ventilation member 26, a receiving device 94, and the like. The indoor unit control section 80 constitutes the control section 200 together with the outdoor unit control section 180 of the outdoor unit 100. Furthermore, the heat exchanger 22 is included in a refrigerant circuit 201 through which refrigerant flows. The indoor unit 10 also includes a first control circuit 81, a second control circuit 82, a third control circuit 83, a phone motor 84, a vertical wind direction plate motor 85, a left and right wind direction plate motor, which are controlled by the indoor unit control section 80. 86, a switching motor 87, etc. In the case of the configuration shown in FIG. 1, an example is shown in which the air cleaning unit 4 that performs an electrostatic precipitator method is controlled by the indoor unit control section 80 as the air cleaning process.

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 section 180, a fourth drive circuit 181, a fifth drive circuit 182, a sixth drive circuit 183, and a fan motor 184. , a valve switching motor 185, a compressor motor 186, and the like.

In the indoor unit 10, the fan 23 is arranged near the heat exchanger 22. The fan 23 guides air sucked in from the room through the suction port of the indoor unit 10 to the heat exchanger 22, and also guides the conditioned air that has been heat exchanged with the heat exchanger 22 to the outlet of the indoor unit 10. The indoor unit control section 80 drives the phone motor 84 with the first control circuit 81 to rotate the fan 23 around the rotation axis. The indoor unit control section 80 can change the rotation speed of the fan 23.

The heat exchanger 22 has, for example, a flow path connected to a refrigerant pipe and a plurality of fins. The heat exchanger 22 exchanges heat between the air sucked in from the room and the refrigerant passing through the flow path.

In the outdoor unit 100, the fan 123 is arranged near the heat exchanger 122. The fan 123 rotates under the control of the outdoor unit control section 180. Thereby, the fan 123 sucks in outside air and guides it to the heat exchanger 122, and discharges the outside air that has been heat exchanged with the heat exchanger 122 to the outside of the outdoor unit 100. The outdoor unit control unit 180 drives the fan motor 184 with the fourth drive circuit 181 to rotate the fan 123 around the rotation axis. The indoor unit control section 80 can change the rotation speed of the fan 123 via the outdoor unit control section 180.

The heat exchanger 122 has, for example, a flow path and a plurality of fins. Heat exchanger 122 is in thermal contact with a refrigerant circuit passing nearby. The heat exchanger 122 exchanges heat with the outside air and the refrigerant passing through the flow path.

Four-way valve 124 is included in refrigerant circuit 201. The four-way valve 124 can switch the refrigerant flow path in the refrigerant circuit 201 between the cooling side and the heating side according to control by the outdoor unit controller 180. The outdoor unit control unit 180 can drive the valve switching motor 185 using the fifth drive circuit 182 to switch the four-way valve 124 between the cooling side and the heating side. The indoor unit control section 80 can switch the four-way valve 124 between the cooling side and the heating side via the outdoor unit control section 180.

Compressor 125 is included in refrigerant circuit 201. The compressor 125 compresses and sends out the refrigerant by the outdoor unit controller 180 under the control of the indoor unit controller 80 . The outdoor unit control unit 180 drives the compressor motor 186 with the sixth drive circuit 183, and causes the compressor 125 to perform a cycle operation of compressing the refrigerant. The indoor unit control section 80 can change the number of cycles of the compressor 125 (the number of times compression cycles are executed per unit time) via the outdoor unit control section 180.

For example, in the air conditioner 1, the control unit 200 (indoor unit control unit 80 and outdoor unit control unit 180) switches the four-way valve 124 to the cooling side in the cooling operation mode. Then, the heat exchanger 22 performs heat absorption processing, causes the refrigerant to absorb heat from the indoor air, and blows out the heat-absorbed conditioned air into the room. Then, heat radiation processing is performed in the heat exchanger 122, and the heat absorbed by the refrigerant is released to the outside air.

Alternatively, in the air conditioner 1, the control unit 200 (indoor unit control unit 80 and outdoor unit control unit 180) switches the four-way valve 124 to the heating side in the heating operation mode. Then, the heat exchanger 122 performs heat absorption processing to cause the refrigerant to absorb heat from the outside air. Then, heat treatment is performed in the heat exchanger 22, the indoor air is heated with the heat absorbed by the refrigerant, and the heated conditioned air is blown into the room.

The vertical wind direction plate 25 and the left and right wind direction plate 29 each set (adjust) the direction of the conditioned air blown into the room. Wind direction means the direction of the wind. In this specification, the indoor unit control unit 80 directly controls the direction in which the vertical wind direction plate 25 and the left and right wind direction plates 29 face. The direction of the wind immediately after it is blown out of the outlet (wind direction) is treated as roughly the same as the direction of the wind. That is, the vertical wind direction plate 25 and the left and right wind direction plates 29 can set (adjust) the wind direction according to their orientation, and the indoor unit control unit 80 controls the orientation of the vertical wind direction plate 25 and the left and right wind direction plate 29, thereby Wind direction can be controlled. Note that the directions of the vertical wind direction plate 25 and the left and right wind direction plates 29 can be controlled individually. As a result, it is possible to blow out air whose wind direction is aligned in one direction from all of the air outlets of the indoor unit 10, or between the air outlets of the indoor unit 10 that are divided by the upper and lower wind direction plates 25, the left and right wind direction plates 29, etc. It is also possible to blow out two or more winds each having a different direction from the above areas.

The vertical wind direction plate 25 can be switched between a closed position and an open position. The vertical wind direction plate 25 closes the air outlet when switched to the closed position. When the vertical wind direction plate 25 is switched to the open position, the air outlet is opened. With the air outlet opened by the operation of the vertical wind direction plate 25, the vertical wind direction plate 25 and the left and right wind direction plate 29 set (adjust) the direction of the conditioned air blown into the room. The vertical wind direction plate 25 sets (adjusts) the wind direction of conditioned air in the vertical direction. The left-right wind direction plate 29 sets (adjusts) the wind direction of the conditioned air in the left-right direction.

A more specific structure of the indoor unit 10 will be described using FIGS. 2 to 10. FIG. 2 is an exemplary and schematic cross-sectional view showing the configuration of the indoor unit 10.

As described above, the indoor unit 10 includes a heat exchanger 22, a fan 23, a filter 24, a plurality of vertical wind direction plates 25 (25A, 25B), and a plurality of left and right wind direction plates 29 inside the casing 21. (See FIGS. 1 and 4), and includes a ventilation member 26 and the like. The vertical wind direction plate 25, the left and right wind direction plate 29, and the ventilation member 26 may also be referred to as a louver.

As shown in each drawing after FIG. 2, in this specification, for convenience, the X-axis, Y-axis, and Z-axis are defined. The X-axis, Y-axis, and Z-axis are orthogonal 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.

Additionally, the X direction, Y direction and Z direction are defined herein. 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 which is the opposite direction 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.

The housing 21 is formed into a substantially rectangular parallelepiped shape extending in the X direction. Note that the housing 21 may be formed in other shapes. The casing 21 is mounted, for example, on a wall of a building (indoor). The housing 21 has an upper surface 21a, a lower surface 21b, and two side surfaces 21e and 21f. 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. Further, the housing 21 has two side walls 21h including side surfaces 21e and 21f, and a spanning portion 21i spanning the two side walls 21h. The spanning portion 21i includes an upper surface 21a and a lower surface 21b.

The housing 21 is provided with a ventilation passage 31, an inlet 32, and an outlet 33. The ventilation path 31 is provided inside the housing 21 . The suction port 32 opens on the upper surface 21a of the housing 21, for example. The air outlet 33 opens on the lower surface 21b of the housing 21, for example. The width direction of the air outlet 33 is along the X direction. Further, the width direction of the air outlet 33 intersects (orthogonally) with the flow direction of the air flowing into the air outlet 33. The suction port 32 and the blowout port 33 may be opened in other parts of the housing 21.

The indoor unit 10 can pass air through the ventilation path 31. Wind is a flow of gas such as air. The suction port 32 is provided at one end of the ventilation passage 31 and communicates the ventilation passage 31 with the outside of the indoor unit 10 . The air outlet 33 is provided at the other end of the ventilation passage 31 and communicates the ventilation passage 31 with the outside of the indoor unit 10 . In other words, the ventilation passage 31 is provided between the suction port 32 and the blowout port 33 inside the housing 21 .

Heat exchanger 22 is provided in ventilation passage 31 . The heat exchanger 22 exchanges heat with surrounding gas in the ventilation passage 31. Thereby, the heat exchanger 22 cools the air flowing through the ventilation path 31 during the cooling operation, and heats the air flowing through the ventilation path 31 during the heating operation.

The fan 23 is provided in the ventilation path 31. The fan 23 sends air from the suction port 32 to the blowout port 33 in the ventilation path 31 by rotating around a rotation axis Axf extending in the X direction. Thereby, the indoor unit 10 sucks indoor air into the ventilation passage 31 from the suction port 32 and blows out the air (wind) in the ventilation passage 31 from the outlet 33. Therefore, in this specification, in the ventilation passage 31, the side closer to the suction port 32 is referred to as upstream, and the side closer to the outlet 33 is referred to as downstream.

Fan 23 is located downstream of heat exchanger 22. Therefore, when the fan 23 generates wind, the air sucked in from the suction port 32 passes through the fins of the heat exchanger 22. Thereby, the air flowing through the ventilation path 31 exchanges heat with the heat exchanger 22.

The filter 24 is provided at the suction port 32 or near the suction port 32 in the ventilation path 31 . Filter 24 is located upstream of heat exchanger 22 . The filter 24 covers the suction port 32 from inside the housing 21 . For example, the filter 24 filters the air sucked in from the suction port 32 and captures dust in the air. As described above, by configuring the filter 24 with a HEPA filter or the like, higher quality air cleaning processing can be achieved.

The vertical wind direction plate 25 and the left and right wind direction plate 29 may be configured as shown in FIGS. 2 to 10. FIG. 2 shows a state in which the vertical wind direction plate 25 is in the closed position Pc1. FIG. 3 is a sectional view showing the configuration and operation of the indoor unit 10, and shows a state in which the vertical wind direction plate 25 is in the open position Po1.

The vertical wind direction plate 25 may include a plurality of vertical wind direction plates 25A and 25B. The vertical wind direction plates 25A and 25B are members that respectively set (adjust) the wind direction of conditioned air in the vertical direction, and are also called vertical louvers. The vertical wind direction plate 25A forms a first flow path C1 for conditioned air, and the vertical wind direction plate 25B forms a second flow path C2 for conditioned air. The upper and lower wind direction plates 25A and 25B each have a shaft portion 41 and a plate portion 42. The first flow path C1 and the second flow path C2 are included in the air outlet 33. That is, the air outlet 33 is divided into a first flow path C1 and a second flow path C2 by a plurality of upper and lower wind direction plates 25A and 25B. In other words, the air outlet 33 has a plurality of partitioned channels (a first channel C1 and a second channel C1) in the inward direction of a plane (YZ plane) orthogonal to the width direction (X direction) of the outlet 33. path C2). The vertical wind direction plate 25A is an example of a first wind direction plate, and the vertical wind direction plate 25B is an example of a second wind direction plate. The first channel C1 and the second channel C2 are examples of branch channels.

The shaft portion 41 is formed into a substantially cylindrical shape extending in the X direction. The shaft portion 41 is rotatably supported by the housing 21 around a rotation axis Axl extending in the X direction. Note that the upper and lower wind direction plates 25A and 25B each have an individual rotation axis Axl. The plate portion 42 protrudes from the shaft portion 41 in a direction substantially perpendicular to the rotation axis Axl. The plate portion 42 is formed into a substantially rectangular plate shape extending in the X direction.

The vertical wind direction plate 25A is supported by a rotating shaft Axl, and the vertical wind direction plate motor 85 is controlled by the second control circuit 82, and the vertical wind direction plate 25A is moved between the closed position Pc1 shown in FIG. 2 and the open position Po1 shown in FIG. It is movable. The vertical wind direction plate 25B is supported by the rotation axis Axl, and the vertical wind direction plate motor 85 is controlled by the second control circuit 82, and the vertical wind direction plate 25B is moved between the closed position Pc1 shown in FIG. 2 and the open position Po1 shown in FIG. It is movable.

As shown in FIG. 2, the vertical wind direction plate 25A, when switched to the closed position Pc1, closes the air outlet 33 that is the outlet of the first flow path C1.

Ru. That is, the directions of the left and right wind direction plates 29-1 to 29-k on the -X side and the left and right wind direction plates 29-(k+1) to 29-2k on the +X side can be independently controlled by the indoor unit control section 80. . The left and right wind direction plates 29-1 to 29-k on the -X side set (adjust) the direction of the wind immediately after being blown out from the area on the -X side (left side) of the air outlet 33, together with the vertical wind direction plate 25A1. However, the left and right wind direction plates 29-(k+1) to 29-2k on the +X side, together with the vertical wind direction plate 25A2, set the direction (wind direction) of the wind immediately after being blown out from the area on the +X side (right side) of the air outlet 33 ( adjust.

The ventilation member 26 shown in FIG. 2 can be switched between a closed position Pc2 and an open position Po2. Specifically, the ventilation member 26 is swingable around the rotation axis Axc between the closed position Pc2 and the open position Po2. The closed position Pc2 is a position where the ventilation member 26 covers (blocks) at least a portion of the air outlet 33 (first flow path C1) opened by the vertical wind direction plate 25A located at the open position Po1. The closed position Pc2 is a position where the ventilation member 26 covers the entire opening in the YZ plane of the air outlet 33 (first flow path C1) opened by the vertical wind direction plate 25A located at the open position Po1. The open position Po2 is a position where the ventilation member 26 does not cover the above-mentioned part of the air outlet 33 (first flow path C1) opened by the vertical wind direction plate 25A located at the open position Po1. That is, the open position Po2 is a position where the ventilation member 26 opens the air outlet 33 (first flow path C1). The ventilation member 26 has an inner surface facing the ventilation path 31 in the closed position Pc2 and an outer surface facing the outside in the closed position Pc2, and has at least one (for example, a plurality of) ventilation ports 56 that are open to the inner surface and the outer surface. It is provided. In the closed position Pc2, the ventilation member 26 has a first blowout passage (first passage C1) through which the air sent by the fan 23 is discharged to the outside through the ventilation opening 56, and a ventilation opening 56. A second blowout flow path (second flow path C2) that is discharged to the outside can be formed adjacent to the first blowout flow path (first flow path C1) without passing therethrough. That is, the ventilation member 26 is inserted into a part of the flow path of the conditioned air blown into the room while being switched to the closed position Pc2, and changes the aperture ratio of the part of the flow path.

In the state where the ventilation member 26 is switched to the open position Po2, the insertion into a part of the flow path is canceled (for example, it is evacuated from a part of the flow path), and the opening ratio of the part of the flow path returns to its original value. will be returned to.

Moreover, in this embodiment, as shown in FIGS. 5 and 7, the ventilation member 26 includes a plurality of (for example, two) ventilation members 26A and 26B. The two ventilation members 26A and 26B are arranged in the left-right direction, that is, in the width direction (X direction) of the air outlet 33. In other words, the two ventilation members 26A and 26B are provided in parallel in the width direction (X direction) of the air outlet 33. The two ventilation members 26A and 26B are rotatable (movable) around the rotation axis Axc independently of each other. The two ventilation members 26A and 26B are driven by separate switching motors 87. Specifically, in this embodiment, separate switching motors 87 are provided for the two ventilation members 26A and 26B. That is, a plurality of switching motors 87 (three as an example) are provided.

The ventilation members 26A and 26B are provided for each of the upper and lower wind direction plates 25A1 and 25A2. In other words, the upper and lower wind direction plates 25A1 and 25A2 are provided for each ventilation member 26A and 26B. That is, the upper and lower wind direction plates 25A1 and 25A2 are arranged in the width direction (X direction) of the air outlet 33 in correspondence with the plurality of ventilation members 26A and 26B. In this embodiment, the upper and lower wind direction plates 25A1 and 25A2, the left and right wind direction plates 29, and the ventilation members 26A and 26B are divided into left and right sides in the width direction of the air outlet 33, but the present invention is not limited thereto. The vertical wind direction plates 25A1 and 25A2, the left and right wind direction plates 29, and the ventilation members 26A and 26B may be divided into three or more in the width direction of the air outlet 33.

In the air conditioner 1, the indoor unit control unit 80 switches the ventilation member 26 to the closed position Pc2 when the windless mode is set as the auxiliary operation mode. The ventilation member 26 is selectively inserted into the first channel C1 while being switched to the closed position Pc2, and changes the aperture ratio of the first channel C1. On the other hand, the aperture ratio of the second channel C2, which is opened and closed by the vertical wind direction plate 25B in which the ventilation member 26 is not present, is maintained as it was. The indoor unit control unit 80 switches the ventilation member 26 to the open position Po2 when the windless mode as the auxiliary operation mode is canceled. The ventilation member 26 is evacuated from the first channel C1 while being switched to the open position Po2, and the aperture ratio of the first channel C1 is returned to its original value.

For example, the 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. FIG. 9 is a perspective view showing the configuration of the ventilation member 26.

As shown in FIG. 3, the ventilation member 26 is housed in the recess 21c of the housing 21 provided near the air outlet 33 in a state of being switched to the open position Po2. The depression 21c is recessed from the inner surface 21d of the housing 21, which forms a part of the ventilation passage 31. The ventilation member 26 located at the open position Po2 is accommodated in the recess 21c, thereby being prevented from interfering with the wind flowing through the first flow path C1.

As shown in FIG. 8, the ventilation member 26 is inserted into the first channel C1 while being switched to the closed position Pc2, and changes the aperture ratio of the first channel C1. In other words, the switching motor 87 places the ventilation member 26 in the closed position Pc2, which is a position that covers (blocks) a part of the first flow path C1 of the air blown by the fan 23. Thereby, the aperture ratio of the first flow path C1 becomes smaller than before the ventilation member 26 is inserted. As shown in FIG. 9, the ventilation member 26 is a member in which a plurality of ventilation holes 56 are arranged in a plate-shaped plate portion 52. The ventilation member 26 is supported by the shaft portion 51, 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. The shaft portion 51 is rotatably supported by the housing 21 around a rotation axis Axc extending in the X direction. That is, the ventilation member 26 is rotatable around the rotation axis Axc. Then, when moving to the closed position Pc2, as shown in FIG. 10, the wind moving in the ventilation passage 31 by the fan 23 passes through the ventilation opening 56 and changes to wind W2a.

On the other hand, the ventilation member 26 is not provided at the air outlet 33 forming the second flow path C2. The aperture ratio of the second channel C2 is maintained as it was. 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 channel C1 and the wind W1a passing through the second channel C2 where the ventilation member 26 is not provided are formed adjacent to each other. .

In this case, the flow velocity of the wind W2a increases as the aperture 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. In addition, the wind W2a that has transitioned to turbulent flow is diffused and hits the wind W1a that flows adjacent to the wind W2a. In this way, the wind W1a and the wind W2a having different flow speeds and conditions (laminar flow or turbulent flow) flow adjacent to each other and collide with each other. That is, the wind W1a that does not pass through the ventilation member 26 (ventilation port 56) and the wind W2a that passes through the ventilation member 26 (ventilation port 56) interfere with each other.

When the wind W1a and the wind W2a hit each other, for example, a lump of the wind W1a and the wind W2a is broken up, and the turbulent wind W2a is carried by the wind W1a. The wind W1a and the wind W2a cause such various interactions and generate a turbulent flow Ws (mixed wind) that spreads over a wide range. As a result, the turbulent flow Ws discharged from the indoor unit 10 becomes closer to natural wind (so-called windless wind) than the wind immediately after discharged from the outlet 33. In this case, the ventilation member 26 may be formed in either the first flow path C1 or the second flow path C2, thereby suppressing an increase in the number of parts, complicating the configuration of the indoor unit 10, and increasing costs. can contribute to Further, the ventilation member 26 has a simple structure including only the ventilation opening 56, which can contribute to suppressing an increase in cost and a decrease in the strength of the ventilation member 26.

Returning to FIG. 1, the radar 2 is capable of detecting the position, moving speed, angle, and shape (height from the floor, etc.) of a detection target (for example, living body CR) indoors. 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 includes a transmitter 2a, a receiver 2b, and a signal processor 2c. The radar 2 generates radio waves such as millimeter waves and microwaves, sound waves, and light in a signal processing unit 2c, transmits them indoors from a transmitting unit 2a, and generates radio waves such as millimeter waves and microwaves, and transmits them into the room from a detection target (biological CR) that may be present in the room. The receiving section 2b receives the waves and passes them to the signal processing section 2c. The radar 2 is provided at any position on the front surface of the casing 21 of the indoor unit 10, and is preferably provided at a position where it can easily detect the position of the detection target (biological CR) indoors. The radar 2 may be embedded at a position near the center in the X direction in the +Y side portion of the housing 21, as shown by dotted lines in FIGS. 2 to 4. Note that it is desirable that the transmitter 2a and the receiver 2b be exposed from the surface of the housing 21, as shown in FIG. Details of the detection processing by the radar 2 will be described later.

FIG. 11 is an exemplary and schematic block diagram showing details of the indoor unit control section 80 of the indoor unit 10 (air conditioner 1) configured as described above.

The CPU that constitutes the indoor unit control section 80 reads out a control program installed and stored in a non-volatile storage device such as a ROM, and implements a module that executes various controls and arithmetic processing according to the program. The indoor unit control section 80 includes modules such as an operation mode control section 80a, a drive circuit control section 80b, a radar control section 80c, an air purification control section 80f, a wind control section 80g, and a temperature monitoring section 80h. Note that each of these modules may be configured by hardware. Moreover, each module may be integrated or divided for each function.

The operation mode control unit 80a switches between the "radar control mode" and the "normal control mode" described above as the operation modes of the indoor unit 10, as well as cooling operation mode, heating operation mode, dehumidification operation mode, humidification operation mode, and ventilation. Switches between operation mode, air purification operation mode, etc. These switching operations are performed based on command signals from the operating terminal 94a operated by the user, or automatically based on the detection results of the radar 2.

The drive circuit control unit 80b controls the first control circuit 81, the second control circuit 82, and the third control circuit based on the operation mode switched by the operation mode control unit 80a and the position of the living body CR included in the detection target existing in the room. The circuit 83 is controlled to control the operations of the fan 23, the vertical wind direction plate 25, the left and right wind direction plate 29, and the ventilation member 26.

The radar control unit 80c controls transmission and reception of the radar 2 (transmission unit 2a, reception unit 2b), and also controls the signal processing unit 2c to obtain analysis results (detection results) of transmitted waves and received waves. Note that the radar 2 may enable the detection process after the indoor unit 10 is activated by operating the operating terminal 94a, or may always stand by in standby mode regardless of the activation of the indoor unit 10 and perform the initial setting, for example. When the movement (motion) of an object (detection target) is detected indoors, normal activation may be performed to obtain information such as the presence or absence of a detection target, the number of detection targets, and shape information of the detection target.

The air purification control unit 80f controls whether or not to perform indoor air purification processing, the efficiency of air purification, etc., depending on the detection status of living body CR in the room. The air cleaning control section 80f controls the air cleaning unit 4, and executes, for example, an electrostatic precipitator type air control process. As described above, the air cleaning unit 4 includes a high-pressure discharge section and the like in order to charge dirt substances such as dust contained in the air sucked in through the suction port 32. In this case, the air purification control unit 80f controls the phone motor 84 via the first control circuit 81 to adjust the strength of the fan 23, thereby adjusting the amount of air sucked from the suction port 32 to improve air purification efficiency. adjustments can be made.

The wind control unit 80g controls the direction of the wind (for example, cooling air, heating air, etc.) blown out from the air outlet 33 and the quality of the blown air, depending on the presence of a detection target (biological CR) in the room that can be detected by the radar 2. control. The wind control unit 80g controls the vertical wind direction plate motor 85 via the second control circuit 82 to control the position of the vertical wind direction plate 25 in the left and right direction. Further, the wind control unit 80g controls the left and right wind direction plate motor 86 via the left and right wind direction plate motor 86 to control the position of the left and right wind direction plate 29 in the left and right direction. The wind control unit 80g can appropriately change the direction (reaching position) of the wind blown out from the air outlet 33 by controlling the direction of the vertical wind direction plate 25 and the left and right wind direction plate 29 in combination. That is, the wind control unit 80g can control the plurality of wind direction setting mechanisms 202 to set the direction of the air blown out from the air outlet 33.

For example, the wind control unit 80g controls other parts of the plurality of wind direction setting mechanisms 202 so that the wind direction is directed toward the living body CR or in a direction that avoids the living body CR, based on the detection result of the radar 2 (biological sensor). (the other of the wind direction setting mechanisms 202A, 202B). For example, the wind control unit 80g can control the wind direction setting mechanism 202 so that the wind always hits the biological body CR, and can improve the refreshing feeling during cooling control, for example. Conversely, the wind control unit 80g finds a position (absent area) where the living body CR does not exist and controls the wind direction setting mechanism 202 so that the wind does not hit the living body CR, thereby reducing the discomfort of being directly hit by the wind. Can be done. Note that the wind control unit 80g may periodically change the direction of the wind to alternately create a state in which the wind blows and a state in which the wind does not blow.

Further, for example, when a plurality of biological CRs (two humans as an example) exist indoors, the wind control unit 80g directs the wind towards one of the humans using one of the two wind direction setting mechanisms 202 (for example, the wind direction setting mechanism 202A). It is possible to make the wind normal strength (momentum) and weaken (gentle) the wind directed toward the other person by using the other of the two wind direction setting mechanisms 202 (for example, the wind direction setting mechanism 202B). Specifically, the wind control unit 80g moves the ventilation member 26 (for example, the ventilation member 26A) provided in one of the two wind direction setting mechanisms 202 (for example, the wind direction setting mechanism 202A) to the open position Po2, and changes the two wind directions. The ventilation member 26 (for example, ventilation member 26B) provided on the other side of the setting mechanism 202 (for example, the wind direction setting mechanism 202B) is moved to the closed position Pc2. As a result, the wind blown out from the other side of the wind direction setting mechanism 202 (for example, the wind direction setting mechanism 202B) is gentler than the wind blown out from one side of the wind direction setting mechanism 202 (for example, the wind direction setting mechanism 202A). That is, the air conditioner 1 can send different types of wind into the room.

Furthermore, when there are multiple biological CRs (two humans as an example) in the room, the wind control unit 80g tracks one of the humans using one of the two wind direction setting mechanisms 202 (for example, the wind direction setting mechanism 202A). It is possible to send wind toward one person, track the other person using the other of the two wind direction setting mechanisms 202 (for example, the wind direction setting mechanism 202B), and send wind to the other person. That is, it is possible to send wind to a plurality of people (for example, two people) who are located at different locations.

Further, the wind control unit 80g can move the vertical wind direction plate 25 to the closed position Pc1, and can move all of the plurality of ventilation members 26A and 26B to the closed position Pc2. The wind control unit 80g also moves the vertical wind direction plate 25 to the closed position Pc1, moves a part of the plurality of ventilation members 26A and 26B (for example, the ventilation member 26A) to the closed position Pc2, and moves the plurality of ventilation members 26A and 26B to the closed position Pc2. , 26B (for example, the ventilation member 26B) can be moved to the open position Po1.

In addition, when swinging (swinging) the upper and lower wind direction plates 25A1 and 25A2 around the rotation axis Ax1, the wind control unit 80g moves the ventilation members 26A and 26B to an open position Po2 that does not interfere with the upper and lower wind direction plates 25A1 and 25A2, i.e. It is moved to the recess 21c of the housing 21. At this time, the wind control unit 80g swings the plurality of vertical wind direction plates 25A1, 25A2 so that the phases of the plurality of vertical wind direction plates 25A1, 25A2 are the same. In other words, the wind control unit 80g swings the plurality of vertical wind direction plates 25A1, 25A2 so that the angles (swing angles) of the plurality of vertical wind direction plates 25A1, 25A2 are the same. Thereby, the plurality of vertical wind direction plates 25A1 and 25A2 periodically reciprocate between the closed position Pc1 and the open position Po1. Moreover, the wind control unit 80g does not swing the vertical wind direction plate 25B when the vertical wind direction plates 25A1 and 25A2 swing. At this time, the vertical wind direction plate 25B is fixed at a predetermined position. The predetermined position is, for example, a position where the thickness direction of the vertical wind direction plate 25B is along the Y direction, but is not limited thereto.

The temperature monitoring unit 80h controls the operation mode control unit 80a based on the temperature (room temperature) provided from the room temperature sensor 3, and executes at least cooling control (control of heat exchange mode) regardless of the operation of the operating terminal 94a. be able to. For example, if a living body CR is detected indoors by the radar 2, and if the indoor temperature deviates from a predetermined temperature by the temperature monitoring unit 80h, for example, if it becomes 32° C. or higher, regardless of the operation of the operating terminal 94a, Cooling control by the indoor unit 10 is started. For example, if the biological CR is a child, infant, pet, etc., and cannot appropriately judge the room temperature or operate the operating terminal 94a, or even if the biological CR is an adult, it may be unable to appropriately judge the room temperature or operate the operating terminal 94a due to illness, etc. Even if this is not possible, the indoor (indoor) temperature can be maintained appropriately. In particular, automatic cooling control is effective in preventing heatstroke and the like (reducing the burden on biological CR). In addition, when a living body CR is detected and the room temperature reaches a predetermined temperature or higher, the temperature monitoring unit 80h cooperates with the wind control unit 80g and blows air toward the detected living body CR for a predetermined time from the start of cooling control. , the body temperature may be lowered efficiently, and after a predetermined period of time has elapsed, the wind blowing direction may be changed to a direction in which no living body CR is present, or the control may be switched to a calm feeling control. In this case, it is possible to effectively reduce the temperature burden on the biological CR, and once the burden on the biological CR is deemed to have been reduced, it is easier to provide a more comfortable indoor environment for the biological CR. Become.

Note that the temperature monitoring unit 80h may automatically perform heating control (control of heat exchange mode) when the room temperature falls below a predetermined temperature. In this case as well, the room temperature can be automatically maintained at a comfortable level, similar to air conditioning control.

As described above, the air conditioner 1 of this embodiment includes the housing 21 and the plurality of ventilation members 26A and 26B. The housing 21 is provided with an outlet 33 that blows out conditioned air indoors. The plurality of ventilation members 26A, 26B are arranged in the width direction (X direction) of the air outlet 33, and each has an open position Po2 where the air outlet 33 is opened, a closed position Pc2 where a part of the air outlet 33 is closed, It is possible to move between. A plurality of ventilation ports 56 are opened in each of the plurality of ventilation members 26A and 26B.

According to such a configuration, by individually setting the positions of the plurality of ventilation members 26A, 26B, different types of wind can be sent into the room at the same time. Therefore, if there are multiple people (for example, two people) who have different desired modes of wind blown out from the air conditioner 1, it is possible to send wind to each person in a mode that suits both of those people's wishes. .

Moreover, the air outlet 33 has a plurality of flow paths (a first flow path C1 and a second flow path C2) divided in an in-plane direction perpendicular to the width direction of the air outlet 33. A plurality of ventilation members 26A, 26B are provided in one or more of the plurality of first channels C1 and second channels C2. In the closed position Pc2, the ventilation members 26A and 26B cover only a part of the first flow path C1, in which the ventilation members 26A and 26B are provided, among the plurality of first flow paths C1 and second flow paths C2. block.

According to such a configuration, air flows from the first flow path C1 partially blocked by the ventilation members 26A and 26B, and from the second flow path C2 that is not blocked by the ventilation members 26A and 26B. A soft breeze can be created by colliding with the wind.

The air conditioner 1 also includes a plurality of upper and lower wind direction plates 25A1 and 25A2 (first wind direction plates). The plurality of upper and lower wind direction plates 25A1 and 25A2 are capable of changing the direction of air blown into the room, and partition the air outlet 33 into a first flow path C1 and a second flow path C2, and the plurality of ventilation members 26A , 26B are arranged in the width direction (X direction) of the air outlet 33.

According to such a configuration, the direction of air blown into the room can be changed by the upper and lower wind direction plates 25A1 and 25A2.

Further, the vertical wind direction plates 25A1 and 25A2 can change the wind direction by swinging. When the vertical wind direction plates 25A1, 25A2 corresponding to the ventilation members 26A, 26B swing, the ventilation members 26A, 26B move to positions where they do not interfere with the vertical wind direction plates 25A1, 25A2.

According to such a configuration, when the vertical wind direction plates 25A1, 25A2 swing, interference between the vertical wind direction plates 25A1, 25A2 and the ventilation members 26A, 26B can be avoided. Therefore, it is easy to increase the swing angle of the vertical wind direction plates 25A1 and 25A2.

Further, the plurality of upper and lower wind direction plates 25A1 and 25A2 swing so that they are in the same phase.

According to such a configuration, indoor air can be stirred.

The air conditioner 1 also includes a vertical wind direction plate 25B (second wind direction plate). The vertical wind direction plate 25B is arranged with the plurality of vertical wind direction plates 25A1 and 25A2 to form a second flow path C2. The vertical wind direction plate 25B can change the direction of the air blown into the room by swinging. The vertical wind direction plate 25B does not swing when the vertical wind direction boards 25A1 and 25A2 swing.

According to such a configuration, the wind direction can be controlled by the vertical wind direction plate 25B while stirring the indoor air.

Next, a modification of the embodiment will be described.

In the first modification, the wind control unit 80g swings the plurality of vertical wind direction plates 25A1, 25A2 so that the phases of the plurality of vertical wind direction plates 25A1, 25A2 are different from each other. That is, the plurality of upper and lower wind direction plates 25A1 and 25A2 swing so that the phases are different from each other. In other words, the swing angles of the plurality of upper and lower wind direction plates 25A1 and 25A2 are different from each other. At this time, it is particularly desirable that the phases of the two left and right upper and lower wind direction plates 25A1 and 25A2 are reversed. In other words, when one of the left and right vertical wind direction plates 25A1 and 25A2 swings upward, it is desirable that the other swings downward.

According to such a configuration, indoor air can be further agitated.

In the second modification, the wind control unit 80g controls the vertical wind direction plate 25B and the vertical wind direction so that the swing movement of the vertical wind direction plate 25B and the swing movement of the vertical wind direction plates 25A1 and 25A2 are in the same phase. The plates 25A1 and 25A2 are swung. That is, the vertical wind direction plate 25B swings in the same phase as the swinging of the vertical wind direction boards 25A1 and 25A2.

According to such a configuration, indoor air can be further agitated. In addition, by matching the phase of the swing of the vertical wind direction plate 25B with the phase of the swing of the vertical wind direction plates 25A1 and 25A2, it is possible to suppress vibration of both.

In addition, although the said embodiment showed the example where the blower outlet 33 was divided into two flow paths (1st flow path C1, 2nd flow path C2), it is not limited to this. For example, the air outlet 33 may be divided into three or more channels, and one or more of these channels may be provided with the ventilation member 26.

Further, in the above-described embodiment, the description has been made assuming, for example, the air conditioner 1 for residential use, but the configuration of the present embodiment is similarly applicable to various types of air conditioners 1. For example, the configuration of this embodiment can also be applied to air conditioners for commercial use (for stores, etc.), and similar effects can be obtained.

Although the embodiments of the present invention have been described above, the above embodiments are merely examples and are not intended to limit the scope of the invention. The embodiments described above can be implemented in various forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. The above-mentioned embodiments are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and its equivalents.
