Embodiment 1 FIG.
FIG. 1 is a schematic diagram illustrating an odor adhesion suppression system according to the first embodiment.

  The odor adhesion suppression system is applied to a room in a building such as a house, for example. FIG. 1 is a plan view of a room R to which the odor adhesion suppression system is applied. As shown in FIG. 1, an air cleaning device 1 and a blower device 2 are provided in the room R.

  The air cleaning device 1 is, for example, an air cleaner. The air cleaning apparatus 1 is installed on, for example, an indoor floor surface. The air cleaning device 1 is installed, for example, at a position approaching one of the wall surfaces from the central portion of the room. For example, the air cleaning device 1 mainly sucks air in the center of the room. The air cleaning device 1 cleans the sucked air. The air cleaning device 1 blows out the cleaned air into the room. The air cleaning device 1 can change the blowing direction of the cleaned air. For example, the air cleaning device 1 blows out the cleaned air toward the blower 2. Hereinafter, the air cleaned by the air cleaning device 1 is also referred to as “cleaned air”.

  The blower 2 is, for example, a room air conditioner indoor unit. The blower device 2 is attached to a wall surface in the room, for example. The air blower 2 is attached to the wall surface which continues to the wall surface nearest to the air purification apparatus 1, for example. The air blower 2 is arrange | positioned at the center in the horizontal direction of a wall surface, for example. The blower 2 sucks indoor air. The blower 2 blows out the sucked air into the room. The blower 2 can blow out air in a plurality of different directions, for example. The blower 2 can change the air blowing direction, for example. The blower 2 blows out air so that, for example, an airflow along a wall surface in the room is formed. The airflow is indicated by a broken line in FIG. The airflow flows along a wall surface continuous with the wall surface on the air blower device 2 side, hits a wall surface facing the wall surface on the air blower device 2 side, and reaches the center of the room. The airflow that reaches the center of the room is sucked into the air cleaning device 1.

  When the air cleaning device 1 blows clean air toward the blower 2, the blower 2 sucks clean air. The blower 2 blows out the sucked purified air into the room. In this case, the air flow indicated by the broken line in FIG. 1 is formed by purified air. That is, the air purifier 1 and the blower 2 are operated in conjunction with each other, and the air direction blown from each is adjusted, whereby the air flow indicated by the broken line in FIG. 1 is formed with the purified air.

  The air cleaning device 1 and the air blower 2 have a communication function. For example, the air cleaning device 1 and the blower 2 are connected to a network built in a house as a communication means. The network is, for example, a wired LAN or a wireless LAN. For example, a cooking device or the like related to the generation of odor may be connected to the network. The cooking appliance related to the generation of odor is, for example, an IH cooking heater or a gas range. Note that the communication between the air cleaning device 1 and the blower device 2 may be performed directly without going through a network, for example.

  At least one of the air cleaning device 1 and the blower 2 has a wall surface detection function. The wall surface detection function is realized, for example, by processing information from a thermal information sensor, a position information sensor, an image sensor, and the like by a control unit (not shown). The thermal information sensor detects thermal information using infrared rays or the like. The position information sensor detects position information of an object using ultrasonic waves or the like. The image sensor is, for example, a camera that detects an image. The wall surface detection function is a function of detecting indoor walls, ceilings, and floors by sensing indoor people, objects, floor plans, doors, windows, and the like with these sensors.

  The thermal information sensor has a function of scanning by moving a plurality of thermopiles arranged in the vertical direction in the horizontal direction. The position of the wall surface in the room can be estimated based on the thermal image obtained by scanning the thermal information sensor, the flow line of the person, the position of the window, and the like.

  The position information sensor has a function of scanning in the horizontal direction, similar to the thermal information sensor. By scanning the position information sensor, it is possible to sense persons, objects, floor plans, doors, windows, and the like existing in the room by acquiring distances from a plurality of objects. As a result, what is in the room can be detected, and the distances between the air cleaning device 1 and the blower 2 and the wall surface, ceiling, and floor surface can be clearly detected.

  A sensor or the like for realizing the wall surface detection function may be provided in at least one of the air cleaning device 1 and the air blowing device 2. A sensor or the like for realizing the wall surface detection function may be provided in another device (not shown) installed indoors. In this case, the air purification apparatus 1 and the air blower 2 should just acquire the information which the sensor etc. detected from the said other apparatus via a communication means. Further, the wall surface detection function may be realized by a user inputting indoor information using a tablet terminal or the like having a communication function.

  At least one of the air cleaning device 1 and the blower 2 has an odor detection function. The odor detection function is a function for detecting or predicting the generation of odor in the room.

  The odor detection function is realized, for example, when the control unit processes information from an odor sensor that detects an odor substance. The odor detection function may predict the generation of odor based on, for example, the behavior of a person detected by a camera or the like. For example, the odor detection function may detect or predict the generation of odor due to cooking by detecting a heat source with an infrared sensor or the like. The odor detection function may predict the generation of odor by, for example, detecting the operation of a cooking appliance related to the generation of odor. The odor detection function may predict the generation of odor by, for example, obtaining operation information of the cooking appliance via the communication means during operation of the cooking appliance.

  A sensor or the like for realizing the odor detection function may be provided in at least one of the air cleaning device 1 and the blower 2. A sensor or the like for realizing the odor detection function may be provided in another device (not shown) installed indoors. In this case, the air purification apparatus 1 and the air blower 2 should just acquire the information which the sensor etc. detected from the said other apparatus via a communication means.

  The odor adhesion suppression system operates in, for example, an odor adhesion suppression mode or an odor removal mode. The odor adhesion suppression mode is a method in which the air cleaning device 1 and the air blower 2 operate in conjunction with each other in order to suppress the odor from adhering to the wall surface. The odor removal mode is a method in which the air cleaning device 1 and the air blower 2 operate in conjunction with each other in order to remove the odor adhering to the wall surface.

  FIG. 2 is a cross-sectional view of the air cleaning device in the first embodiment. The left surface in FIG. 2 is the front of the air cleaning device 1. The right side surface in FIG. 2 is the back surface of the air cleaning device 1.

  As shown in FIG. 2, the air cleaning device 1 includes a casing 3, a pedestal 4, a horizontal rotation mechanism 5, a blower 6, a cleaning unit 7, and a movable louver 8. The blower 6 and the cleaning unit 7 are accommodated in the casing 3. The casing 3 is formed with an inlet 9 and an outlet 10.

  The casing 3 is, for example, a vertically long tower-type case that is formed into a substantially rectangular square tube shape and extends in a direction perpendicular to the floor surface. The pedestal 4 is in contact with the installation surface of the air cleaning device 1. For example, the air cleaning device 1 is installed indoors with the pedestal 4 in contact with the floor surface. The horizontal rotation mechanism 5 has a rotation shaft (not shown). The casing 3 is supported by the pedestal 4 via a rotating shaft. The casing 3 rotates in the horizontal direction around the rotation axis.

  The suction port 9 is an opening for taking indoor air into the casing 3. As shown in FIG. 2, the suction port 9 opens, for example, on the front surface of the casing 3. The suction port 9 has, for example, a vertically long opening shape extending in the vertical direction. The suction port 9 may be formed on the back surface, side surface, or bottom surface of the casing 3.

  The air outlet 10 is an opening for discharging the air inside the casing 3 to the outside of the casing 3. As shown in FIG. 2, the air outlet 10 opens, for example, on the upper surface of the casing 3. The blower outlet 10 exhibits the horizontally long opening shape extended in the left-right direction, for example. The air outlet 10 may be formed on the front surface or the side surface of the casing 3.

  The blower 6 generates an air flow from the inlet 9 to the outlet 10. That is, the blower 6 sucks air into the casing 3 from the suction port 9 and blows out the air inside the casing 3 from the outlet 10 to the outside. The air volume of the blown air from the blower outlet 10 changes according to the rotational speed of the blower 6.

  As shown in FIG. 2, the air cleaning device 1 includes, for example, two fans 6 a and 6 b as the blower 6. The blower 6a is disposed on the front side and the upper side of the blower 6b. The blower 6b is disposed on the back side and the lower side of the blower 6a. The air cleaning device 1 may include only one or three or more blowers 6.

  The cleaning unit 7 is disposed between the suction port 9 and the blower 6. That is, the cleaning unit 7 is located upstream of the blower 6 inside the casing 3. The cleaning unit 7 cleans the air sucked into the casing 3 from the suction port 9. Cleaning means collecting, inactivating or decomposing at least odor molecules. The cleaning unit 7 may collect, inactivate, or decompose dust, smoke, pollen, viruses, molds, fungi, allergens, and the like floating in the air in addition to odor molecules. Specifically, the cleaning unit 7 is, for example, a filter or a voltage application device. Moreover, the cleaning part 7 is comprised by combining these, for example.

  The movable louver 8 is disposed at the air outlet 10 via a louver drive unit (not shown). The louver drive unit changes the angle of the movable louver 8 in the front-rear direction. That is, the movable louver 8 adjusts the wind direction of the air blown out from the blowout port 10 in the vertical direction.

  As shown in FIG. 2, the air cleaning device 1 includes, for example, a movable louver 8 a and a movable louver 8 b as the movable louver 8. The movable louver 8a and the movable louver 8b are arranged side by side in the front-rear direction. The movable louver 8a changes the wind direction of the air blown out from the blower outlet 10 by driving the blower 6a. The movable louver 8b changes the wind direction of the air blown out from the blower outlet 10 by driving the blower 6b. Note that the air cleaning device 1 may include only one or three or more movable louvers 8.

  FIG. 3 is a first perspective view of the air cleaning device in the first embodiment. FIG. 4 is a second perspective view of the air cleaning apparatus in the first embodiment. 3 and 4 show an upper surface, a front surface, and a side surface of the air cleaning device 1. 3 and 4 are schematic views for explaining a schematic structure, and are not necessarily consistent with other drawings.

  3 and 4 show the movable louver 8 and the rectifying mechanism of the air cleaning device 1. The rectifying mechanism includes, for example, a fin 11 standing on the wind receiving surface of the movable louver 8 and a fin driving unit (not shown). The plurality of fins 11 are arranged at regular intervals along the left-right direction. The fin driving unit changes the angle of the plurality of fins 11 in the left-right direction. That is, the rectifying mechanism adjusts the air direction of the air blown from the outlet 10 in the left-right direction. FIG. 3 shows a state in which the wind direction is adjusted to the left as viewed from the front side of the air cleaning device 1. FIG. 4 shows a state in which the wind direction is adjusted to the right when viewed from the front side of the air cleaning device 1.

  With the above configuration of the air cleaning device 1, the orientations of the casing 3, the movable louver 8, and the fins 11 can be adjusted. That is, the direction in which air is sucked into the suction port 9 can be adjusted in the left-right direction. Moreover, the wind direction of the air which blows off from the blower outlet 10 can be adjusted up and down, right and left. For this reason, the air purification apparatus 1 can convey the blown-out air with respect to the air blower 2, for example.

  As shown in FIGS. 3 and 4, a sensor unit 12 is provided on the front surface of the air cleaning device 1. The sensor unit 12 is, for example, a sensor for realizing at least one of a wall surface detection function and an odor detection function. The sensor unit 12 may be provided on the upper surface, the side surface, or the back surface of the air cleaning device 1. Moreover, the sensor part 12 may be provided in the several location of the air purification apparatus 1. FIG.

  FIG. 5 is a perspective view of the air blower in the first embodiment.

  As shown in FIG. 5, the front upper portion of the blower 2 is covered with a front panel 13. A suction port 14 is formed on the upper surface of the blower 2. An air outlet 15 is formed in the lower part of the blower 2. Below the front panel 13, an up / down air direction plate 16a, an up / down air direction plate 16b, an up / down air direction plate 16c, and an up / down air direction plate 16d are provided. A plurality of left and right wind direction plates 17 are provided on the back side of the up and down wind direction plate 16a, the up and down wind direction plate 16b, the up and down wind direction plate 16c, and the up and down wind direction plate 16d.

  The up / down wind direction plate 16 a is disposed in the upper left portion of the air outlet 15. The vertical wind direction plate 16 b is disposed in the upper right part of the air outlet 15. The up / down wind direction plate 16 c is disposed in the lower left portion of the air outlet 15. The up-and-down wind direction plate 16 d is disposed in the lower right part of the air outlet 15. The vertical wind direction plate 16 a and the vertical wind direction plate 16 b are arranged side by side with a slight gap as if they were divided at the center in the longitudinal direction in the front view of the blower 2. The up-and-down air direction plate 16c and the up-and-down air direction plate 16d are arranged side by side with a slight gap as if they were divided at the center in the longitudinal direction in the front view of the blower 2.

  Supporting arms (not shown) are provided at opposing portions of the up / down wind direction plate 16a, the up / down wind direction plate 16b, the up / down wind direction plate 16c, and the up / down wind direction plate 16d. A support (not shown) is rotatably attached to the support arm via a pin (not shown). A support shaft (not shown) is provided on the opposite side of the up / down air direction plate 16a, the up / down air direction plate 16b, the up / down air direction plate 16c, and the up / down air direction plate 16d. The support shaft is detachably supported by a bearing (not shown) on the side wall of the air outlet 15. Each support shaft is provided so as to be able to rotate independently by driving a motor. The driving of the motor is controlled by a wind direction control unit (not shown). When the angle in the front-rear direction of the up-and-down air direction plate 16a, the up-and-down air direction plate 16b, the up-and-down air direction plate 16c, and the up-and-down air direction plate 16d is changed, the air direction of the air blown from the outlet 15 is changed in the up-and-down direction.

  The plurality of left and right wind direction plates 17 are arranged side by side along the longitudinal direction of the blower device 2 as viewed from the front. The left and right wind direction plates 17 are supported by control shafts so as to be individually controllable. When the angle in the left-right direction of the left-right wind direction plate 17 changes, the wind direction of the air blown out from the blower outlet 15 changes in the left-right direction.

  With the above-described configuration of the blower device 2, the air direction of the air blown out from the air outlet 15 can be adjusted vertically and horizontally. For this reason, the air blower 2 can blow air toward the indoor wall surface, ceiling, and floor surface. Moreover, the air blower 2 can blow so that the wind direction of the air which blows off from the left part of the blower outlet 15 and the wind direction of the air which blows off from the right part of the blower outlet 15 differ, for example.

  As shown in FIG. 5, a sensor unit 12 is provided on the front surface of the blower 2. The sensor unit 12 is, for example, a sensor for realizing at least one of a wall surface detection function and an odor detection function. In addition, the sensor part 12 may be provided in the several location of the air blower 2. FIG.

  FIG. 6 is a cross-sectional view of the blower device in the first embodiment. FIG. 6 shows a cross section viewed from the right side in the front view of the blower 2.

  As shown in FIG. 6, the blower 2 includes a blower 18 and a heat exchanger 19 inside. The blower 18 is provided below the inlet 14 and above the outlet 15. The heat exchanger 19 is provided between the suction port 14 and the blower 18.

  The blower 18 is provided so as to be rotationally driven by a fan motor (not shown). The air volume of the air blown from the air outlet 15 changes according to the rotation speed of the fan motor. A fan motor control unit (not shown) performs control to change the rotation speed of the fan motor. The heat exchanger 19 heats or cools the air blown from the blower outlet 15.

  FIG. 7 is a first flowchart for explaining an operation example of the odor adhesion suppressing system in the first embodiment. FIG. 7 shows an operation example in the odor adhesion suppression mode. In the example shown in FIG. 7, an odor detection function is realized based on information from an odor sensor that detects the odor concentration.

  At least one of the air cleaning device 1 and the blower 2 determines whether or not odor is generated indoors by the odor detection function (step S101). Specifically, for example, when an odor concentration exceeding a preset reference value is detected, it is determined that odor is generated indoors. If it is determined in step S101 that no odor is generated indoors, the operation in step S101 is repeated.

  When it is determined in step S101 that odor is generated indoors, the air cleaning device 1 conveys the cleaning air to the blower 2 (step S102). Specifically, the air cleaning device 1 controls the air direction so that air is blown out in the direction of the blower 2 by the movable louver 8 and the horizontal rotation mechanism 5 or the rectifying mechanism. By this operation, the purified air is conveyed to the suction port 14 of the blower 2.

  The air direction control by the air cleaning device 1 in step S102 may be performed based on, for example, position information of the air blower 2 obtained through communication with the air blower 2. The said wind direction control may be performed based on the positional information on the preset air blower 2, for example. The said wind direction control may be performed based on the positional information on the air blower 2 detected using the sensor part 12 of the air purification apparatus 1, for example. The said wind direction control may be performed based on the positional information on the air purifying apparatus 1 detected using the sensor part 12 of the air blower 2, for example. The said wind direction control may be performed based on the information which the user input using the tablet terminal etc. which have a communication function, for example.

  The purified air conveyed by the air cleaning device 1 in step S102 is sucked from the suction port 14 of the blower device 2. The purified air sucked from the suction port 14 is cooled by the heat exchanger 19 and blown out from the blowout port 15 as cold air. At this time, the purified air is blown out in two directions toward the two wall surfaces detected in advance by the wall surface detection function. That is, the air blower 2 conveys clean air as cold air to the wall surface (step S103). Specifically, the air blower 2 controls the air direction so that an airflow is formed along the wall surface in the room and air is blown out simultaneously on both the left and right sides in the front view of the air blower 2. In addition, the air volume of the air blower 2 may be preset and may be adjusted according to an indoor odor density | concentration etc.

  When the purified air is conveyed by the blower 2 in step S103, a cold airflow formed by the purified air is generated near the wall surface (step S104). The cold airflow suppresses the attachment of odorous substances to the wall surface. Moreover, the odorous substance is conveyed to the central part of the room by the cold airflow. Thereby, the odor density | concentration of the indoor center part which is the suction space of the air purification apparatus 1 becomes high. That is, the odorous substance present in the room is suppressed from adhering to the wall surface by the cold airflow, and gathers in the suction space of the air cleaning device 1 (step S105).

  At least one of the air cleaning device 1 and the blower 2 determines whether or not the indoor odor concentration is equal to or lower than a reference value by the odor detection function (step S106). If it is determined in step S106 that the odor concentration is not lower than the reference value, the operation in the odor adhesion suppression mode is continued.

  In step S106, when it is determined that the odor concentration is equal to or lower than the reference value, the operation in the odor adhesion suppression mode ends. Also, when the stop operation is performed by the user, the operation in the odor adhesion suppression mode ends.

  In addition, in the odor adhesion suppression mode, the determination that the odor is generated indoors may be performed by detecting a heat source of a cooking appliance such as a gas range or an IH cooking heater, for example. The determination may be performed, for example, by detecting the operation of the cooking appliance. The determination may be performed in conjunction with the operation of the cooking appliance, for example. Moreover, even if the determination is not performed, the operation in the odor adhesion suppression mode may be started by the user manually operating the air cleaning device 1 and the air blower 2.

  FIG. 8 is a second flowchart for explaining an operation example of the odor adhesion suppressing system in the first embodiment. FIG. 8 shows an example of operation in the odor removal mode. In the example shown in FIG. 8, the odor detection function is realized based on information from the odor sensor that detects the odor concentration.

  At least one of the air cleaning device 1 and the blower 2 determines whether or not odor is attached to the room by the odor detection function (step S201). Specifically, for example, when an odor concentration exceeding a preset reference value is detected, it is determined that the odor is attached to the room. If it is determined in step S201 that no odor is attached to the room, the operation in step S201 is repeated.

  If it is determined in step S201 that odor is attached to the room, the operation in step S202 is performed. The operation in step S202 is similar to the operation in step S102.

  The purified air conveyed by the air cleaning device 1 in step S202 is sucked from the suction port 14 of the blower device 2. The purified air sucked from the suction port 14 is heated by the heat exchanger 19 and blown out from the outlet 15 as warm air. At this time, the purified air is blown out in two directions toward the two wall surfaces detected in advance by the wall surface detection function. That is, the air blower 2 conveys clean air as warm air to the wall surface (step S203). Specifically, the air blower 2 controls the air direction so that an airflow is formed along the wall surface in the room and air is blown out simultaneously on both the left and right sides in the front view of the air blower 2. In addition, the air volume of the air blower 2 may be preset and may be adjusted according to an indoor odor density | concentration etc.

  When the cleaning air is conveyed by the blower 2 in step S203, a warm air flow formed with the cleaning air is generated near the wall surface (step S204). When the temperature of the wall surface rises due to the warm air flow, the odor adhering to the wall surface easily diffuses into the air. Thereby, the odor adhering to the wall surface is removed and conveyed to the central part of the room by the warm airflow. Thereby, the odor density | concentration of the indoor center part which is the suction space of the air purification apparatus 1 becomes high. That is, the odorous substance adhering to the wall surface is removed from the wall surface by the warm air current and gathers in the suction space of the air cleaning device 1 (step S205).

  At least one of the air cleaning device 1 and the blower 2 determines whether or not the indoor odor concentration is equal to or lower than a reference value by the odor detection function (step S206). If it is determined in step S206 that the odor concentration is not lower than the reference value, the operation in the odor removal mode is continued.

  In step S206, when it is determined that the odor concentration is equal to or lower than the reference value, the operation in the odor removal mode ends. Also, when the user performs a stop operation, the operation in the odor removal mode ends.

  Note that, in the odor removal mode, the determination that the odor is adhered to the room may be performed, for example, when a high odor concentration is detected in a state where there is no odor generation operation such as operation of the cooking appliance. The operation in the odor removal mode may be started, for example, when the user manually operates the air cleaning device 1 and the air blower 2. The operation in the odor removal mode may be started, for example, when it is detected that no one is inside the room. The operation in the odor removal mode may be performed at regular time intervals based on, for example, a timer. The operation in the odor removal mode may be programmed to be performed in a preset time zone in which no person is present. The time zone without people is, for example, nighttime.

  In the first embodiment, the odor adhesion suppressing system includes an air cleaning device 1 and a blower 2. The air purification apparatus 1 is provided indoors and cleans indoor air. The air blower 2 blows out the air cleaned by the air cleaning device 1 into the room so that an air flow along the wall surface of the room is formed. According to Embodiment 1, when the airflow formed with the clean air is generated in the vicinity of the wall surface, it is possible to suppress the odor from adhering to the wall surface. For this reason, even if odors such as cooking odors and tobacco odors are generated indoors, odors are unlikely to accumulate on the wall surface. As a result, it is possible to maintain the comfort of the room such as a living room and to extend the lifetime of the wall surface and wallpaper.

  In the first embodiment, at least one of the air cleaning device 1 and the blower 2 detects the wall surface in the room by the wall surface detection function. The air blower 2 changes the air blowing direction by the left and right wind direction plates 17 so that air is conveyed to each of the two detected wall surfaces. According to the first embodiment, the airflow flows along two wall surfaces continuous to the wall surface on the air blower 2 side, then hits the wall surface facing the wall surface on the air blower 2 side, and reaches the center of the room. For this reason, the odor which generate | occur | produced indoors gathers in the center part of an indoor, without approaching any wall surface. As a result, it is possible to suppress odor from adhering to each wall surface in the room.

  In the first embodiment, the air cleaning device 1 sucks and cleans the air in the center of the room and blows out the cleaned air toward the blower 2. According to the first embodiment, the air cleaning device 1 cleans the air in the center of the room, which is a region where the odor concentration is increased by the airflow. For this reason, indoor air can be efficiently cleaned. In addition, the air purification device 1 conveys the purified air to the periphery of the blower device 2. For this reason, the airflow along the wall surface can be formed with purified air.

  In the first embodiment, at least one of the air cleaning device 1 and the air blowing device 2 detects indoor odor by the odor detection function. The air cleaning device 1 and the air blower 2 start operation based on the detection result of odor. According to Embodiment 1, when a specific detection result is obtained by the odor detection function, the air cleaning device 1 and the blower 2 are operated in conjunction with each other. For this reason, the airflow which suppresses adhesion of an odor can be generated only when necessary.

  In Embodiment 1, when it is detected that odor is generated in the room by the odor detection function, the blower 2 cools the cleaned air with the heat exchanger 19 and blows it out into the room. Thereby, compared with the case where airflow is formed with normal temperature air, an odor can be made hard to adhere to a wall surface. As a result, it is possible to more effectively suppress odor from adhering to the wall surface.

  In Embodiment 1, the blower 2 heats the cleaned air with the heat exchanger 19 and blows it into the room when it is detected by the odor detection function that the odor is attached to the room. Thereby, compared with the case where airflow is formed with normal temperature air, an odor can be easily diffused from a wall surface. As a result, it is possible not only to suppress the attachment of odor but also to remove the odor attached to the wall surface.

  When the cool air is blown from the blower 2 in the odor adhesion suppression mode, if the person in the room feels cold, the blower 2 may be operated in the blower mode. For example, the air blower 2 may be set not to perform cooling in the odor adhesion suppression mode during the winter period. Even in this case, an effect of suppressing the odor from adhering to the wall surface in the room can be obtained.

  In the odor removal mode, when a person in the room feels hot when hot air is blown from the blower 2, the blower 2 may be operated in the blower mode. For example, the air blower 2 may be set not to perform heating in the odor removal mode during the summer season. Even in this case, an effect of suppressing the odor from adhering to the wall surface in the room can be obtained.

  The air blower 2 may change the air blowing direction so that air is simultaneously conveyed to each of the ceiling and floor detected by the wall surface detection function. In this case, the airflow formed flows along each of the ceiling and the floor, hits the wall facing the wall on the blower 2 side, and reaches the center of the room. For this reason, the odor which generate | occur | produced indoors gathers in the indoor center part, without approaching any of a ceiling and a floor surface. As a result, it is possible to suppress odor from adhering to the indoor ceiling and floor.
