(Embodiment 1)
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the air blower 1 according to the first embodiment as viewed from the front, FIG. 2 is a perspective view of the blower 1 as viewed from the rear, and FIG. 3 is a side view with the exterior cover removed. The white arrow of FIGS. 1-3 has shown the distribution | circulation route and distribution direction of the air by an air blower.

  The blower device 1 includes a rotating part 2 at the upper part and an installation part 3 at the lower part. The rotating unit 2 includes an air outlet and a suction port and houses the air blowing mechanism. The rear portion of the installation portion 3 includes a power cord 8 and a power plug (not shown) provided at the tip thereof. The blower 1 is supplied with power via the power cord 8.

  The rotation unit 2 is disposed on the installation unit 3 so as to be rotatable. The rotating part 2 is formed with a circular bottom surface, and a lower part has a conical shape, and is formed in a substantially rectangular parallelepiped shape from a substantially central part to the upper end in the vertical direction.

  Further, the rotation unit 2 has a swing motor 27 at the lower portion, and when the swing motor 27 is driven, the swing unit 2 swings left and right around the rotation shaft 2a. On the back surface of the rotating unit 2, a gripping unit 10 that is recessed in the rotating unit 2 is provided. The user holds the grip 10 and carries the blower 1.

  The rotating unit 2 includes a suction port 4 that opens to the lower side surface, an air outlet 5 that opens to the upper front surface, and a blower passage 20. The blower passage 20 disposed in the rotating unit 2 extends in the vertical direction and connects the blower outlet 5 and the blower fan 7.

  The suction port 4 is provided with a dust collection filter (not shown) that collects dust, and a ventilation plate 9 having a plurality of ventilation holes is provided outside the dust collection filter as an outer shell.

  The air sucked from the suction port 4 is sucked into the blower fan 7 after coarse dust is removed by the dust collecting filter. The environmental condition detection means for detecting temperature, humidity, dust and the like is arranged in any part of the ventilation path. Each of the temperature detection means, the humidity detection means, and the dust detection means may be normally used, and is also widely available on the market, and the description thereof is omitted.

  A downstream portion of the air passage 20 in the air flow direction extends upward and curves forward. A downstream portion of the air passage 20 is divided into six ventilation paths 22 by five partition plates 21.

  The inlet part 23 of the ventilation path 22 is located immediately downstream of the location where the ion generator 30 described later is disposed, and the outlet part 24 is located immediately upstream of the outlet 5. The six ventilation paths 22 are arranged in a line in the front-rear direction of the blower 1 at the inlet 23 and in a line in the vertical direction at the outlet 24.

  Six movable louvers 25 are provided between the outlet portion 24 of the ventilation path 22 and the outlet 5. Each of the movable louvers 25 is attached continuously to the five partition plates 21 and the lowermost wall plate of the outlet portion 24 at their upstream ends. The movable louver 25 is connected to the louver motor 26 on the downstream side. When the louver motor 26 is driven, the downstream end portions of the six movable louvers 25 are aligned and displaced vertically in a predetermined cycle.

  A blower fan 7 made of a sirocco fan is disposed below the blower passage 20. An intake port (not shown) of the blower fan 7 is adjacent to the suction port 4, and an exhaust port 7 a of the blower fan 7 is connected upward to the inlet portion 23 of the air flow path 20. The blower fan 7 circulates the air sucked from the suction port 4 toward the blower outlet 5.

  An ion generator 30 is disposed above the blower fan 7. Ions generated by the ion generator 30 are included in the airflow flowing through the air passage 20.

  The ion generator 30 is disposed downstream of the blower fan 7 in the air flow direction. The ion generator 30 includes a positive ion generator and a negative ion generator (both not shown). The positive ion generator includes a positive discharge electrode (not shown), and the negative ion generator includes a negative discharge electrode (not shown). The two pairs of the positive discharge electrode and the negative discharge electrode are each formed in a needle shape, arranged side by side at a predetermined interval, and arranged facing the blower passage 20.

  The ion generator 30 is supplied with a high voltage generated by the high-voltage electricity generation circuit to the positive discharge electrode and the negative discharge electrode, generates an air discharge, and releases ions. Here, a voltage having an AC waveform or a pulse waveform is applied to the positive discharge electrode and the negative discharge electrode of the ion generator 30.

A positive voltage is applied to the positive discharge electrode, and hydrogen ions are combined with moisture in the air by corona discharge to generate positive ions mainly composed of H ⁺ (H ₂ O) m. A negative voltage is applied to the negative discharge electrode, and oxygen ions are combined with moisture in the air by corona discharge to generate negative ions mainly composed of O ₂ ^— (H ₂ O) n. Here, m and n are arbitrary natural numbers.

H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odorous components in the air and surround them. Then, as shown in the following formulas (1) to (3), an activated species [.OH] hydroxyl radical or H ₂ O ₂ hydrogen peroxide is generated on the surface of a microorganism or the like by collision of both ions. This function destroys airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers.

Therefore, when the ion generator 30 discharges the air flowing through the air passage 20 so as to include positive ions and negative ions generated by the discharge at the positive discharge electrode and the negative discharge electrode, for example, Indoor sterilization and deodorization can be performed.

_{^{H + (H 2 O) m}} + O 2 - (H 2 O) n → · OH + 1 / 2O 2 + (m + n) H 2 O · (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 · OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

An operation panel 6 is disposed on the upper surface of the rotating unit 2 of the blower 1 of the present invention. FIG. 4 is a front view of the operation panel 6. A plurality of operation buttons are provided on the operation panel 6 formed by a touch panel. The operation buttons include an operation button 6a, air volume switching buttons 6b and 6c, an ion mode button 6d, a filter replacement lamp 6e, a reset button 6g, a swing button 6h, and a louver button 6j. The operation panel 6 may be provided on the outer surface of the rotating unit 2.

  In addition, a control device 60 is provided inside the rotation unit 2. The operation performed on the operation panel 6 is transmitted to the control device 60 and processed by a built-in CPU (central processing unit) to drive or stop the blower fan 7, the ion generator 30 and the like.

The operation button 6a switches ON / OFF of the power supply of the air blower 1, and when the power is turned ON, driving of the air blower fan 7 and the ion generator 30 is started. The air volume switching buttons 6 b and 6 c adjust the air volume of the blower 1. The operation button 6a is arranged on the rotation shaft 2a so that the position does not move due to the rotation even during the swinging operation. The ion mode button 6d changes the generation of ions, the amount of air blown, and the direction of airflow to diffuse ions. The degree can be controlled and the vehicle is operated in a preset operation mode.

  The filter replacement lamp 6e composed of an LED light source is turned on when it is time to replace a dust collection filter (not shown). The reset button 6g turns off the filter replacement lamp 6e that is pressed and lit during filter replacement.

  The swing button 6h continuously stops the swing operation when pressed when the swing operation of the rotating unit 2 is temporarily stopped, and starts the swing operation when pressed when the swing operation is stopped. In the swing operation, the swing angle in the left-right direction can be set in five stages. When the swing button 6h is turned on, the swing operation is performed with the initially set left-right angle width of 15 °. The swing angle can be changed by pressing a swing button of a remote controller (not shown), and the swing angle width is set to 15 ° → 30 ° → 60 ° → 90 ° → 120 ° → 15 °.

  When the swing button 6h is operated for the first time after the blower device 1 is turned on, the control device 60 automatically detects and stores the center position in the left-right direction by turning the turning unit 2 left and right. . After determining the center position, the control device 60 rotates the rotating unit 2 so that the left and right swing widths are the same angle.

  The louver button 6j turns the movable louvers 25, 25,. When pressed when the vertical swing motion is stopped, the vertical swing motion is started. If pressed during the vertical swing motion, the vertical swing motion is stopped. Further, by operating the louver button of the remote controller, the direction of the movable louver 25 can be changed in a cycle of horizontal → upward → horizontal → downward → horizontal, and can be fixed in each direction.

  The space 6f between each operation button can detect that the user contacted with the touch panel.

  In addition, an imaging unit 15 is provided on the upper portion of the rotating unit 2. In this embodiment, the imaging means 15 is a small camera used for a mobile phone or the like. The obtained video data is stored in the control device 60 or in another recording device.

  In the air blower 1 having the above configuration, an operation during standby will be described. In the standby mode, the power cord 8 is connected to the power source, but the blower 1 stops operation when the user does not operate the operation button 6a or the ion mode button 6d or the timer operation that can be set with the remote control is completed. It is in a state of being. In this case, the operations of the blower fan 7, the ion generator 30, the movable louver 25, and the swing motor 27 are stopped, and the corresponding displays are also turned off.

  However, in the present invention, the control device 60 is always energized when the air blower 1 is on standby, and is kept in a state that can accept input from the operation button 6a and other operation input means. Further, the energization is continued to the environmental condition detecting means, and the blower 1 can monitor the temperature, humidity, and air pollution level even during standby. The detection result is output to the control device 60. FIG. 5 shows the relationship between the operation input and the control output as a control block.

  FIG. 6 shows a control flow for the standby operation. The standby operation will be described according to the control flow.

  When the blower 1 stops operating and enters a standby state, measurement of the time elapsed from the stop of operation is started by the time measuring means of a CPU (central processing unit) (not shown) in the control device 60.

  Next, in step 1 (S1), it is determined whether or not any of the operation buttons has been operated from the operation panel 6. When the operation is performed (Yes in S1), the operation content is accepted, the standby state is terminated, and the driving operation corresponding to the operation content is performed.

  When the operation is not performed (No in S1), the process proceeds to Step 2. In step 2 (S2), it is determined whether or not the predetermined time 1 determined in advance has elapsed. The predetermined time 1 is a time interval for intermittently operating the blower fan 7 to acquire environmental conditions, and may be about 5 minutes, for example.

  When the time has elapsed (Yes in S2), the rotating unit 2 is rotated in the left-right direction, and the indoor situation is photographed.

  Next, the process proceeds to step 3 (S3), and it is determined whether or not there is a person in the room from the obtained indoor image. The method for extracting a person from image data has already been put into practical use and will not be described. Further, by storing the previous image data in the control device 60 and taking a difference from this data, it can be determined that the person has entered the predetermined range or has left the predetermined range.

  If it is determined that there is no person in the predetermined range (No in S3), if an alarm has already been issued, this is canceled and the process returns to Step 1 (S1) to wait for an operation input from the operation panel 6. .

  If it is determined in step 3 that there is a person in the predetermined range (Yes in S3), the directions of the movable louvers 25, 25 are changed upward to be stationary. The air outlet 5 is provided with a plurality of movable louvers 25. By moving the end of the leeward side to the uppermost position, the movable louvers 25, 25 are overlapped to form an armored door. The airflow blown out from the can be suppressed. FIG. 7 schematically shows the state at that time.

  Even if a gap is generated between the movable louvers 25, 25, since the direction of the movable louver 25 is upward, the leaked air current is blown out upward of the blower 1, so that direct air hitting the user is avoided. It is done.

  Next, the blower fan 7 is driven for a short time, and the environmental condition detection means acquires information such as the room temperature, humidity, and dirt. The blower fan 7 is stopped after being energized for a time period for starting the motor, for example, for several seconds to several tens of seconds. The blower fan 7 continues to rotate due to inertia for a while. As a result, the air sucked by rotating the blower fan 7 at a rotational speed of about 100 rpm reaches the environmental condition detection means.

  The interval at which the blower fan 7 is intermittently operated is not particularly strict, but if the interval is too short, power is unnecessarily consumed. Also, if it is too long, it will not play a role in monitoring in summer. Moreover, monitoring and energy saving can be achieved by shortening the interval to several minutes in summer and increasing the interval to several tens of minutes in winter. Specifically, it is possible to adopt a control method such as shortening the interval when the room temperature during standby exceeds a certain temperature, for example, 27 ° C., and increasing the interval when the temperature is less than 27 ° C.

  The environmental condition detection means is installed in the middle of the air blowing path between the suction port 4 and the blower outlet 5 and can come into contact with the surrounding air through the vent holes of the blower outlet 5 and the vent plate 9. By detecting, change is detected more quickly.

  Further, the operation of the blower fan 7 is not limited as long as the airflow from the fan can reach the environmental condition detection means, and the airflow does not need to blow out from the outlet 5. Therefore, the blower fan 7 is supplied with a pulse current having a width sufficient for starting the motor, but the time required for starting varies depending on the type and characteristics of the motor. Is preferred.

  If the rotational speed of the blower fan 7 reaches about 100 rpm, the purpose of sucking air and reaching the environmental condition detection means can be achieved, so that the lowest rotational speed is, for example, energized only for several seconds to several tens of seconds. This can be realized by setting the pulse width to.

  In step 4 (S4), it is determined whether or not the detected environmental condition is within a predetermined range by the CPU of the control device 60. The determination is made based on FIG. For example, if the temperature and humidity conditions are in the area A or B in FIG. 8, it is determined that the temperature and humidity conditions are within the predetermined range (Yes in S4), the alarm issued so far is canceled, and the process proceeds to Step 1. Returning, it is determined whether or not there is an input from the operation panel 6.

  If the detected temperature and humidity are in the area C or D in FIG. 8, it is determined that the temperature and humidity have deviated from the predetermined range (No in S4), an alarm is issued and a display is performed. Thereafter, the process proceeds to step 5 (S5), and an operation of waiting for whether or not any operation is performed during the predetermined time 2 is performed.

  The predetermined time 2 is a time waiting for the user who has detected the alarm to respond, and for example, about 15 minutes is set.

  If the predetermined time 2 has not elapsed (No in S5), the process returns to step 1 and waits for an input from the operation panel 6. If the user notices the alarm during the predetermined time 2 and there is any operation input (Yes in S1), the standby operation is terminated and the operation corresponding to the operation content is performed.

  If the user does not operate the blower 1 and adjusts the temperature and humidity with another air conditioner or the like, the predetermined time 2 has elapsed (Yes in S5), and indoor shooting and notification are issued. Then, the process returns to Step 1.

  According to the control flow again, when step 2 and step 3 are passed and the process proceeds to step 4 (S4), if the environmental condition is changed and improved, the determination in step 4 is changed from No to Yes. In this case, the alarm is stopped and the process returns to step 1 to continue the standby operation.

  If the user does not operate the blower 1 and does not operate other air conditioners, and if the predetermined time 2 has passed without any response (Yes in S5), the indoor situation is photographed with the third person. An abnormality is reported together with the video data to a predetermined report destination.

The reporting means is a mobile phone, for example, and can be set to report to a predetermined destination. Further, the reporting means may be communication via mobile radio or the Internet, or may be communication using an extension telephone or a public telephone line. In addition, the report destination may be a predetermined mobile phone, or may be an individual or an organization such as a care facility or a security company.
(Embodiment 2)
In the present embodiment, when the blower fan 7 is driven during standby, the blower outlet 5 is directed to either end of the rotation range in the left-right direction and stopped. FIG. 9 shows a control flow. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment.

  Compared with the first embodiment, the difference is only whether the movable louver 25 is turned upward before the blower fan 7 is driven, or the turning part 2 is turned to direct the blowout port 5 in the direction where no one is present. Other operations are the same.

  A place where there is no person is designated from the data obtained by the imaging means 15, and the air outlet 5 is stopped to face there. Alternatively, the air outlet 5 is simply stopped toward the left end or the right end of the rotation range. In this embodiment, since the maximum left / right swing angle width is 120 °, it is swung 60 ° to the right or left with respect to the center of rotation. If it is simply directed to the left end or the right end of the rotation range, the control becomes simple.

  Since the rotation range is recognized when the swing button 6h is operated for the first time after the power cord 8 of the blower 1 is connected to the power source, the outlet is located at the right end or the left end of the rotation range unless the power supply itself is interrupted. 5 can be turned.

Also, when using the swing function when the user is alone in the room, the user generally tends to use it near the center of the horizontal rotation range. Even if the airflow leaks from the air outlet 5, it is possible to avoid the airflow from directly hitting the user.
(Embodiment 3)
This embodiment is a combination example of the first embodiment and the second embodiment. FIG. 10 shows a control flow. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment.

  Direct hitting of the user can be avoided by simply closing the blower outlet 5 with the movable louver 25 facing upward or by making the rotating part 2 stationary toward either the left or right end of the rotating range. However, both are implemented in this embodiment.

By doing so, even if the rotational speed of the blower fan 7 during intermittent operation varies somewhat, the influence of the airflow on the user is reduced, and it is not necessary to strictly monitor the rotational speed. In other words, there are variations in the width of the drive pulse and the motor characteristics, and even if the target rotational speed is exceeded, the user does not get a direct wind and avoids discomfort.
(Embodiment 4)
In the present embodiment, a human sensor 16 is used instead of the imaging means 15 used as the means for detecting a person in the first embodiment. FIG. 11 shows an external perspective view. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment. In the air blower 100, by using an infrared sensor as the human sensor 16, the function close to that of the first embodiment can be achieved at a very low cost.

  When detecting by the human sensor 16, the detection lower limit temperature is adjusted by an optical filter or the like. In a normal room, people and pets are subject to detection, but adults have the lowest body temperature, and children and pets are naturally detected. Detecting non-adult organisms is not particularly inconvenient and need not be excluded.

  The detection range can be adjusted by the mounting structure of the human sensor 16. For example, the light receiving window of the human sensor 16 is made into a slit shape or a deep well shape to limit the direction of incident infrared rays.

The other structure is the same as that of the first embodiment, and the control flow is the same as that of FIG. Also in the second and third embodiments, it is possible to control using the human sensor 16 instead of the photographing unit 15.
(Embodiment 5)
FIG. 12 is a perspective view showing a blower device 200 according to the fifth embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment. This embodiment is a combination example with the first embodiment and the fourth embodiment. In addition to the imaging means 15, a human sensor 16 is provided. Other configurations are the same as those of the first embodiment.

  The indoor situation is acquired by the imaging means 15 and the human detection is performed by the human sensor 16, thereby eliminating the need for advanced data processing for detecting a person from the video obtained by the imaging means 15. Since only the person is detected by the human sensor 16 and the image taken by the imaging means is simply attached and notified, the respective data can be processed without being processed variously. For this reason, the control device 60 and data processing can be simplified.

  The control flow is the same as in the first embodiment, and refer to FIG. Basic operation steps 1 to 5 (S1 to S5) are performed in the same manner as in the first embodiment.

  At the time of entering the standby state, measurement of elapsed time is started, and whether or not there is an operation input in step 1 and the elapsed time of intermittent operation is determined in step 2.

  When the predetermined time 1 has elapsed and the time for intermittent operation has come, the presence of a person is determined in step 3. When a person is detected within a predetermined range, the movable louvers 25 and 25 are made to stand still so as not to apply airflow to the person. The detection of the person in step 3 determines the input by the human sensor 16.

  Next, in step 4 (S4), it is determined whether or not the environmental condition is within a predetermined range. If the environmental conditions are not within the specified range, an alarm is issued and displayed. In this state, during the time set as the predetermined time 2, the user waits for corresponding input from the operation panel 6. As the predetermined time 2, for example, about 15 minutes is set.

  When there is an input from the operation panel 6 during the waiting time (Yes in S1), the standby operation is terminated and the operation corresponding to the operation is performed.

  If the user adjusts the temperature and humidity with another air conditioner or the like without operating the blower 200, the predetermined time 2 has passed (Yes in S5), and a predetermined notification destination is set. Is returned to step 1.

  When step 2 and step 3 have elapsed according to the control flow and the process has again shifted to step 4 (S4), a change in the environmental condition is detected, and the determination in step 4 changes from No to Yes. In this case, the alarm is stopped and the process returns to step 1 to continue the standby operation. In such a case, it is preferable to report again that the alarm has been canceled.

  When the user does not operate the blower 200 and does not operate another air conditioner and the predetermined time 2 elapses (Yes in S5), the imaging unit 15 captures the indoor situation. , Notify the third party, a predetermined reporting destination.

  Return to Step 1 again after reporting, pass through Step 2 and Step 3 according to the control flow, and when the process goes back to Step 4 again, no change in environmental conditions is detected, so the judgment in Step 4 remains Yes Is done. In such a case, after the elapse of the predetermined time 2, the notification is made again to the predetermined report destination.

  Thus, when the control flow circulates and notification is made many times, it is preferable to change the notification destination or add the notification destination. When an elderly person living alone or an infant is left in such an environment, an emergency response may be required.

  INDUSTRIAL APPLICABILITY The present invention can be used as a function for watching an elderly person living alone or an infant in an air conditioner or a blower having an environmental condition detection means.
