FIG. 2 is a diagram showing an example of a configuration of a main part of the humidifier 1 according to the first embodiment. As shown in FIG. 2, the humidifier 1 includes a humidifier main body 18A and a person determination unit 18B. The humidifier main body 18A is a communication unit for transmitting and receiving information between the steam generating unit 4 and the fan 5 described above, the first control unit 15 for controlling them, and the first control unit 15 for transmitting and receiving information between the human determination unit 18B. 31 and. The person determination unit 18B includes a person detection unit 19 that detects a state such as the distance from the humidifier 1 to the sleeper and the posture of the sleeper, a registration unit 20 for registering information on the sleeper, and a person detection unit 19. The second control unit 21 that processes the signal from the registration unit 20 and generates information to be transmitted to the first control unit 15 of the humidifier main body 18A, and the second control unit 21 provides information between the humidifier main body 18A. It is provided with a communication unit 32 for transmitting and receiving. In the humidifier 1, the person determination unit 18B monitors the posture of a sleeping person during the operation of the humidifier, and the humidifier main body 18A performs a humidifying operation or a blowing operation based on the monitoring result. The description of the person detection unit 19, the registration unit 20, the second control unit 21, the communication unit 31, and the communication unit 32 is omitted in FIG.

The human detection unit 19 detects and monitors a part of the body such as the face and head of the sleeping person. The human detection unit 19 is realized by, for example, an infrared sensor and an image sensor, and includes an image acquisition unit 191 that acquires a certain range of thermal images and images including a sleeping person's face and head, and at least one of an ultrasonic sensor and a Doppler sensor. A distance detection unit 192, which is realized by using one or more and detects a distance between each object existing in a certain range including a sleeping person's face and head and a humidifier 1, is provided.

The registration unit 20 acquires and registers information on the sleeping person to be monitored. For example, the registration unit 20 senses the image of the sleeping person's face and the heat distribution of the head by sensing the user's face with the person detecting unit 19 in a state where the user's face is arranged at a predetermined distance from the humidifier 1 before going to bed. Get information and register. Registration here means storing and storing the acquired information in a memory (not shown). The registration unit 20 acquires an image of the sleeping person's face by analyzing the image acquired by the image sensor of the image acquisition unit 191 of the person detection unit 19. Further, the registration unit 20 acquires information on the heat distribution of the head by analyzing the thermal image acquired by the infrared sensor of the image acquisition unit 191 of the human detection unit 19. The above-mentioned "state in which the user's face is placed at a predetermined distance from the humidifier 1 before going to bed" is, for example, a state in which the sleeping person is lying on bedding such as a bed or a futon. For example, when the sleeping person performs an operation of instructing information registration by using a remote controller (hereinafter, referred to as a remote controller) in which the humidifier 1 is not shown, the registration unit 20 displays an image of the sleeping person's face and Obtain information on the heat distribution of the head.

When the humidifier 1 performs the humidifying operation, the second control unit 21 analyzes the image acquired by the image acquisition unit 191 of the person detection unit 19 to detect the position of the sleeping person's face, and further, the humidifier 1 The distance from the sleeper to the sleeper's face is detected based on the position of the sleeper's face and the distance between each object detected by the distance detection unit 192 and the humidifier 1. That is, the second control unit 21 selects a distance corresponding to the position of the face detected by analyzing the image from the distances to each object detected by the distance detection unit 192, and from the humidifier 1 to the sleeping person. The distance to the face. When the second control unit 21 detects the position of the sleeping person's face, the registration unit 20 acquires and stores the image of the sleeping person's face and the heat of the head in a memory (not shown). Use at least one of the distribution information. When the second control unit 21 detects the distance from the humidifier 1 to the face of the sleeping person, the second control unit 21 generates a control signal indicating the detection result and transmits it to the first control unit 15 of the humidifier main body 18A via the communication unit 32. do.

In this way, the person determination unit 18B of the humidifier 1 detects the position of the face before going to bed, registers or stores the information, and uses the stored information to determine the position of the sleeping person's face. To detect. Therefore, the humidifier 1 can distinguish the face of the sleeping person from other heat source devices such as the lighting around the sleeping person and the charger of the mobile terminal, and erroneously detects the other heat source device as the sleeping person. Can be prevented and the accuracy of detecting a sleeping person is improved.

The first control unit 15 of the humidifier main body 18A controls the steam generation unit 4 and the fan 5 based on the control signal received from the second control unit 21. The details of the operation in which the first control unit 15 controls the steam generation unit 4 and the fan 5 will be described later.

The first control unit 15 of the humidifier main body 18A, the second control unit 21 and the registration unit 20 of the person determination unit 18B are realized by, for example, the processor 101 and the memory 102 shown in FIG. Further, the communication unit 31 of the humidifier main body 18A and the communication unit 32 of the person determination unit 18B are realized by the communication device 103 shown in FIG. Here, the processor 101 is a CPU (Central Processing Unit, a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, a processor, a DSP), a system LSI (Large Scale Integration), and the like. The memory 102 is a non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), and EPROM (Electrically Erasable Programmable Read Only Memory). And so on. The first control unit 15, the second control unit 21, and the registration unit 20 provide a program for the processor 101 to operate as the first control unit 15, the second control unit 21, or the registration unit 20 stored in the memory 102. It is realized by reading and executing. The first control unit 15 and the second control unit 21 are realized by different processors 101 and memory 102, respectively. The second control unit 21 and the registration unit 20 may be realized by the same processor 101 and the memory 102, or may be realized by different processors 101 and the memory 102, respectively.

Next, the operation of blowing the humidified air by the humidifier 1 will be described with reference to FIGS. 4 to 6. 4 to 6 are views showing an example of the positional relationship between the humidifier 1 and the sleeping person according to the first embodiment. FIG. 4 shows the positional relationship between the sleeping person before going to bed and the humidifier 1. The sleeping person presses a specific button (not shown) of the remote controller in order to operate the person determination unit 18B constituting the humidifier 1 in the state before going to bed shown in FIG. As a result, the person determination unit 18B starts the operation. A sleeping person at a position separated from the humidifier 1 by a predetermined distance, for example, 50 cm away from the humidifier 1, holds his / her face over the person determination unit 18B installed in front of the humidifier 1 to determine the person 18B. Sensing A is performed by the above, and the face and head of the sleeping person are determined and the distance from the humidifier is detected. It is assumed that the registration unit 20 stores and manages the information obtained by executing the sensing A in the memory. When the sensing A is completed, the steam B from the humidifier 1 is generated, and the humidified steam is conveyed around the face of the sleeping person. The operation of the human determination unit 18B executing the sensing A is an operation as an initial position detection unit, that is, an operation as an initial position detection unit that detects an initial position which is the position of the user's face at the start of the humidification operation. Applicable.

For sleeping people, the posture of the sleeping person often changes irregularly due to turning over. As shown in FIG. 5, when the position of the sleeping person's face becomes closer to the humidifier 1 than the initial position, that is, the position detected by executing the above sensing A due to turning over, the person determination unit 18B determines the position before going to bed. In the operating state of the humidifier 1 at the time when the face position is detected, the humidity may be excessively humidified with respect to the humidity suitable for sleep, which is a factor that hinders comfortable sleep.

In such a case, the person determination unit 18B detects that the distance between the sleeping person's face and the humidifier 1 is smaller than that at the time of determination by the sensing A before going to bed, and humidifies a control signal indicating that. It is transmitted to the first control unit 15 of the device main body 18A. The first control unit 15 controls to reduce the fan rotation speed of the fan 5 and to reduce the heating amount of the heating unit 4b of the steam generating unit 4 based on the control signal received from the second control unit 21. By executing at least one of them, the amount of steam B transported is suppressed.

As described above, when the distance from the sleeping person becomes small due to turning over, the humidifier 1 can suppress over-humidification by suppressing the amount of steam generated or the amount of air blown, and can maintain an environment suitable for sleep. ..

Further, as shown in FIG. 6, when the position of the sleeping person's face is farther from the humidifier 1 than the initial position due to the sleeping person turning over, the person determination unit 18B determines the position of the humidifier 1 and the sleeping person's face. Detects that the distance is greater than before bedtime. In this case, the person determination unit 18B sends a control signal indicating that the distance between the sleeping person's face and the humidifier 1 is larger than that at the time of determination by the sensing A before going to bed. Send to 15. The first control unit 15 controls to increase the fan rotation speed of the fan 5 and to increase the heating amount of the heating unit 4b of the steam generating unit 4 based on the control signal received from the second control unit 21. By performing at least one of them, the amount of steam B transported is increased.

In this way, the humidifier 1 can increase the humidity around the face and suppress drying by increasing the amount of steam generated or the amount of air blown when the distance from the sleeping person becomes large due to turning over. It is possible to maintain a suitable environment for sleep. After the humidifier 1 starts the humidification operation, the person determination unit 18B operates as a user detection unit that detects the position of the face of the user who is a sleeping person, and the first control unit 15 operates the steam in the humidification operation. It operates as a humidification amount control unit that controls the amount of air generated and the amount of air blown.

A flowchart of the operation of the humidifier 1 is shown in FIG. The operation shown in FIG. 7 starts when the sleeping person is instructed to start the operation of the humidifier 1 by performing an operation such as pressing a specific button on the remote controller. When the humidifier 1 is instructed to start the operation, first, as shown in FIG. 7, the humidifier 1 first detects the face of the sleeping person (step S1) and registers it. In this step S1, the person determination unit 18B of the humidifier 1 executes the above-mentioned sensing A to determine the face and head of the sleeping person and detect the distance from the humidifier 1. Next, the humidifier 1 starts a humidifying operation (step S2). After starting the humidifying operation, the humidifier 1 confirms whether or not the position of the sleeping person's face has changed (step S3), and if there is no change, confirms whether or not the specified time has elapsed (step). S7). The specified time is a time set by the sleeping person until the humidification operation is completed, that is, a time for performing the humidification operation. If the specified time is not set by the sleeping person, the specified time shall be the specified time. For example, 3 hours, 6 hours, etc. are set as predetermined predetermined times. When the specified time has elapsed (step S7: Yes), the humidifier 1 ends the humidification operation. If the specified time has not elapsed (step S7: No), the humidifier 1 returns to step S3 and continues the operation.

When the position of the sleeping person's face changes (step S3: No), the humidifier 1 confirms whether or not the sleeping person's face position is far from the initial position (step S4), and when it is farther than the initial position. (Step S4: Yes), the amount of humidification is increased (step S5). That is, the first control unit 15 of the humidifier 1 executes at least one of a control for increasing the fan rotation speed of the fan 5 and a control for increasing the heating amount of the heating unit 4b of the steam generating unit 4. Increase the amount of steam transported toward the sleeping person's face. After executing step S5, the humidifier 1 returns to step S3 and continues the operation. The humidifier 1 reduces the amount of humidification when the position of the sleeping person's face is closer than the initial position (step S4: No) (step S6). That is, the first control unit 15 of the humidifier 1 executes at least one of a control for reducing the fan rotation speed of the fan 5 and a control for reducing the heating amount of the heating unit 4b of the steam generating unit 4. Reduce the amount of steam transported towards the sleeping person's face. After executing step S6, the humidifier 1 returns to step S3 and continues the operation.

In the operation shown in FIG. 7, the amount of steam transported is decreased when the distance to the initial face position of the sleeping person is used as a reference, and the amount of steam transported is increased when the distance is far from the standard. However, the control of the amount of steam transported is not limited to this. For example, the amount of steam transported may be determined in advance according to the distance to the sleeping person's face, and the amount of steam transported may be determined according to the detected distance.

Further, as shown in FIG. 8, the humidifier 1 may have a second wind direction plate 22 inside, and may be electrically connected to the first control unit 15 together with the first wind direction plate 8. .. FIG. 8 is a top view of the humidifier 1 according to the first embodiment. In the configuration shown in FIG. 8, the humidifier 1 changes the steam transport direction in the vertical direction by the first wind direction plate 8 according to the position of the sleeping person's face detected by the person determination unit 18B. The second wind direction plate 22 changes the steam transport direction to the left and right. As a result, for example, even when the sleeping person turns over and the humidifier 1 shifts the face position with respect to the direction in which the steam is conveyed, as shown in FIG. 9, the second wind direction plate 22 As a result, steam can be transported toward the sleeper's face, the steam transport direction can be flexibly changed according to the posture of the sleeper, and an environment suitable for sleep can be maintained.

As described above, the humidifier 1 according to the first embodiment detects the distance to the sleeping person's face and changes the amount of steam transported based on the detection result. For example, when the distance to the sleeping person's face is reduced, the amount of steam transported is reduced, and when the distance is increased, the amount of steam transported is increased. As a result, it is possible to maintain a suitable environment for sleeping even when the sleeping person turns over and the position of the face changes.

In the present embodiment, the humidifier 1 having a configuration in which the humidifier main body 18A and the human determination unit 18B are housed in one housing has been described, but the humidifier main body 18A and the human determination unit 18B are separated from each other. It may be configured to be housed in the body. In that case, the communication unit 31 of the humidifier main body 18A and the communication unit 32 of the person determination unit 18B perform wireless communication to transmit and receive control signals.

Further, in the present embodiment, the case where the humidifying operation is performed for the sleeping person has been described, but the target of the humidifying operation may be other than the sleeping person. For example, the target of the humidification operation may be a user during desk work with little facial movement.

Embodiment 2.
In this embodiment, the environmental control system 23 realized by using the humidifier 1 according to the first embodiment will be described. As for the environmental control system 23, FIG. 10 is a diagram showing a configuration example of the environmental control system 23 according to the second embodiment.

The humidifier 1a is a humidifier having a configuration in which the human determination unit 18B is deleted from the humidifier 1 described in the first embodiment.

FIG. 11 is an external view of the air conditioner 24 according to the second embodiment. As shown in FIG. 11, for example, the air conditioner 24 sets the room temperature with a remote control (not shown) that allows the user to set the room temperature, thereby providing the air conditioning means and the room temperature detection inside. While detecting the room temperature by means (not shown), the room temperature and humidity are adjusted by cooling, blowing, dehumidifying or heating. Further, the air conditioner 24 includes at least one third wind direction plate 25 that changes the wind direction of the wind C sent by the blower means (not shown) in the horizontal direction and the vertical direction in order to adjust the temperature and humidity in the room. I have the above. Each of the third wind direction plates 25 can be controlled independently, and the wind direction and the air volume of the wind C can be changed according to the instruction signal from the remote controller and the signal indicating the temperature detection result by the room temperature detecting means.

Further, the air conditioner 24 is provided with a human determination unit 18 having the same configuration as the human determination unit 18B of the humidifier 1 described in the first embodiment on the front surface of the housing, that is, the surface on the side where the wind C is blown out. Similar to the person determination unit 18B described in the first embodiment, the person determination unit 18 includes a person detection unit 19, a registration unit 20, a second control unit 21, and a communication unit 32.

The human detection unit 19 receives, for example, the amount of infrared rays emitted from an object by a plurality of light receiving units to which dissimilar metals are bonded, and processes an electromotive force due to a temperature difference between dissimilar metals due to the Seebeck effect in an arithmetic circuit. By using the thermopile method that measures the surface temperature of the measurement area, it is possible to detect the temperature in the room, the presence or absence of people in the room, the attributes of adults or children, and the temperature distribution of people. The human detection unit 19 is provided with a filter (not shown) having a characteristic of passing infrared rays and blocking light in other bands outside the light receiving unit, and the filter blocks visible light to block sunlight and bathroom. It may be configured to reduce the influence of moisture on the measured temperature.

Further, the human detection unit 19 has a function of acquiring a plurality of thermal images or real images by scanning and determining the presence or absence of a human body from the temperature difference from the background, and a function of discriminating between an exposed portion and a non-exposed portion of the skin. , And may have a function of detecting the movement of a person, and may function as a sensible temperature sensor for detecting the sensible temperature. In this case, the more exposed the skin is, the easier it is to detect. Further, the larger the number of pixels, the higher the detection accuracy.

In addition, the human detection unit 19 can grasp the distance to the human body to be air-conditioned and the position of the human body in the room by analyzing the thermal image or the actual image acquired by scanning. In addition, the human detection unit 19 can also detect a part of the human body based on the exposed skin position. In addition, the person detection unit 19 measures the information acquired by the image sensor or the infrared sensor over time to determine the positional relationship between the person in the room and the air conditioner 24, the turning over that occurs to the sleeping user, and the like. It is also possible to detect the body movement of. The means for detecting the distance, the part, and the body movement by the human detection unit 19 is not limited to this.

The second control unit 21 of the person determination unit 18 transmits a control signal indicating the detection result by the person detection unit 19 to the humidifier 1a. The humidifier 1a performs the same control as the humidifier 1 according to the first embodiment according to the control signal received from the second control unit 21 of the human determination unit 18. That is, the difference between the humidifier 1a according to the second embodiment and the humidifier 1 according to the first embodiment is controlled based on the determination result by the person determination unit 18 provided in the air conditioner 24. The control is performed based on the determination result of the person determination unit 18B provided inside, and the respective control operations are the same.

FIG. 12 is a diagram showing a configuration example of the air conditioner 24 according to the second embodiment. The air conditioner 24 includes the above-mentioned person determination unit 18 and an air conditioning unit 40 that adjusts at least one of the set temperature and the air flow rate based on the determination result of the person determination unit 18. The air-conditioning unit 40 detects the room temperature and adjusts the temperature and humidity of the room which is the air-conditioning target space by cooling, blowing, dehumidifying or heating based on the detection result, that is, performing air conditioning. Since the air conditioning operation itself is the same as the conventional one, the details thereof will be omitted. Further, the air conditioner 40 includes parts similar to those provided for air conditioning in a general air conditioner indoor unit, such as a heat exchanger, a blower fan, a motor, a power converter, a sensor, and a microcomputer. However, in FIG. 4, the description of those parts is omitted.

Next, the environmental control system 23 according to the second embodiment will be described. FIG. 13 is a flowchart showing an operation example of the environmental control system according to the second embodiment.

As shown in FIG. 13, in the environmental control system 23, the air conditioner 24 first detects the face of the sleeping person (step S11) and registers it. This step S11 is the same process as step S1 of FIG. 7 described in the first embodiment. The registration process in step S11 is performed by the person determination unit 18 provided in the air conditioner 24. Next, the humidifier 1a starts the humidifying operation (step S12), and the air conditioner 24 starts the air conditioning operation (step S13). After the air conditioner 24 starts operating, the person determination unit 18 of the air conditioner 24 confirms whether or not there has been a change in the position of the sleeping person's face (step S14), and if there is no change (step S14: Yes). ), It is confirmed whether or not the number of body movements of the sleeping person within a certain period of time is equal to or less than the threshold value (step S18).

When the number of body movements of the sleeping person within a certain period of time is equal to or less than the threshold value (step S18: Yes), the air conditioner 24 confirms whether or not the specified time has elapsed (step S20). The specified time is the same as the specified time described in the first embodiment, and is the time until the air conditioner 24 and the humidifier 1a finish operating. When the specified time has elapsed (step S20: Yes), the air conditioner 24 and the humidifier 1a end their operation. In this case, the person determination unit 18 of the air conditioner 24 instructs the humidifier 1a to end the operation. If the specified time has not elapsed (step S20: No), the air conditioner 24 returns to step S14 and continues the operation.

When the position of the sleeping person's face changes (step S14: No), the person determination unit 18 confirms whether or not the sleeping person's face position is far from the initial position (step S15), and is farther than the initial position. In the case (step S15: Yes), the humidifier 1a increases the amount of humidification (step S16). That is, when the person determination unit 18 detects that the position of the sleeping person's face is far from the initial position, the person determination unit 18 transmits a control signal indicating that fact to the humidifier 1a, and the humidifier 1a points the sleeping person's face toward the sleeping person's face. Increase the amount of steam transported. After executing step S16, the environmental control system 23 returns to step S14 and continues the operation. Further, when the person determination unit 18 detects that the position of the sleeping person's face is closer than the initial position (step S15: No), the humidifier 1a reduces the amount of humidification (step S17). That is, when the person determination unit 18 detects that the position of the sleeping person's face is closer than the initial position, the person determination unit 18 transmits a control signal indicating that fact to the humidifier 1a, and the humidifier 1a points the sleeping person's face toward the sleeping person's face. Reduce the amount of steam transported. After executing step S17, the environmental control system 23 returns to step S14 and continues the operation.

When the number of body movements of the sleeping person within a certain period of time is greater than the threshold value (step S18: No), the air conditioner 24 adjusts the set temperature and the air volume (step S19). The number of body movements of a sleeping person within a certain period of time is highly related to the depth of sleep, and it can be estimated that when the number of body movements is large, the sleep is shallow, and when the number of body movements is small, the sleep is deep. That is, when the number of body movements within a certain period of time is greater than the threshold value, it is presumed that the sleeping person has a shallow sleep depth due to a hot or cold condition. Therefore, in step S19, the air conditioner 24 adjusts at least one of the set temperature and the air volume to reduce the heat and cold of the sleeping person and maintain a suitable sleeping environment. For example, the air conditioner 24 controls in step S19 to lower the set temperature or increase the air volume when the cooling operation is performed, and raises the set temperature in step S19 when the heating operation is performed. And so on. After executing step S19, the environmental control system 23 returns to step S14 and continues the operation.

As described above, the environmental control system 23 according to the present embodiment includes the air conditioner 24 and the humidifier 1a, switches the operation of the humidifier 1a according to the change in the position of the sleeping person's face, and for a certain period of time. The operation of the air conditioner 24 is switched according to the number of body movements of the sleeping person in the room. As a result, the same effect as that of the humidifier 1 according to the first embodiment can be obtained, and the temperature can be adjusted to realize a more suitable sleeping environment.

Further, since the air conditioner 24 installed at a high position in the room is provided with the person determination unit 18, the positions of the sleeping person and the humidifier 1a can be monitored from a high position, and whether or not the sleeping person is turned over. , And the positional relationship between the sleeping person and the humidifier 1a can be determined more accurately. As a result, more accurate control becomes possible.

In the example shown in FIG. 13, the operation of the air conditioner 24 is switched based on the number of body movements, but the operation of the humidifier 1a may also be switched. For example, when the number of body movements within a certain period of time is greater than the threshold value, the humidifier 1a stops the humidifying operation and switches to the blowing operation, reduces the rotation speed of the fan, and reduces the amount of steam generated and the transport distance. , The humidification operation may be paused, and the like.

The configuration shown in the above-described embodiment shows an example of the content of the present invention, can be combined with another known technique, and is one of the configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
