Description

  The present invention relates to a pollen removing apparatus that removes pollen disposed on an entrance to a room and attached to a human body.

  A conventional pollen removing device is disclosed in Patent Document 1. This pollen removing apparatus includes a blower duct provided with a blower fan and a spray unit for spraying mist. By driving the blower fan, the airflow is sent from above or from the side toward the human body from the outlet provided in the blower duct. In addition, mist having an average particle size of 10 μm or less is sprayed from the spray port toward the human body.

  The air around the human body is humidified by spraying mist, and static electricity charged on the human body is removed. At this time, since the mist needs to have a large surface area for static elimination, the mist is formed in an ultrafine mist state with an average particle diameter of 10 μm or less. As a result, the mist immediately evaporates and the human body does not get wet, and fogging of glasses or the like can be prevented. And the pollen and dust adhering to a human body are easily peeled off by the airflow by removing static electricity, and the pollen and dust can be removed.

  However, according to the conventional pollen removing device, the mist sprayed from the spraying part is formed into an ultrafine mist, so that it evaporates immediately, and dry pollen and dust reattach to the human body and enter the room. It was. Moreover, when the air volume of the blower fan is increased so that pollen and dust peeled from the human body can reach the floor surface, there is a problem that a lot of electric power is required and the user's discomfort increases.

  An object of this invention is to provide the pollen removal apparatus which can remove the pollen adhering to a human body by reliably preventing discomfort with low electric power.

  In order to achieve the above object, the present invention provides a pollen removal apparatus that removes pollen attached to a human body and disposed at an entrance to a room, and a ventilation duct that opens a suction port and an outlet, and is disposed in the ventilation duct. The pollen which is provided in the air duct, has an ion generator for generating positive ions and negative ions, and a spray unit for spraying mist from the spray port, and is peeled off from the human body by an air flow containing ions. It is characterized by depositing mist on the floor and allowing it to settle to the floor.

  According to this configuration, outside air is sucked into the blower duct through the suction port by driving the blower fan. The airflow flowing through the air duct includes positive ions and negative ions generated by the ion generator, and the airflow containing the ions is sent out from the outlet toward the human body. Moreover, mist is sprayed from the spraying port of the spraying part. The static electricity charged on the human body is removed by the air stream containing ions, and the pollen attached to the human body is peeled off. Mist adheres to the pollen peeled from the human body, and the pollen settles down to the floor surface by the weight of the mist.

  Further, the present invention provides the pollen removing apparatus having the above-described configuration, wherein the blower outlet is disposed above the human body standing up to blow ions downward from the blower outlet, and the spray port is disposed on the floor surface so as to be upward. It is characterized by spraying mist. According to this structure, the airflow containing ion is sent from the upper part of a human body via a blower outlet, and the pollen which peeled from the human body is guide | induced downward. Mist sprayed from the spray port arranged on the floor surface adheres to pollen and settles to the floor surface.

  Moreover, the present invention is characterized in that in the pollen removing apparatus having the above-described configuration, the spray height of the mist sprayed from the spray port is lower than the height of the lower half of the human body.

  Moreover, the present invention is characterized in that in the pollen removing apparatus having the above-mentioned configuration, the spraying section sends a water flow to the floor surface after stopping spraying of mist. According to this configuration, when the spraying of mist by the spraying unit is stopped, the user enters the room, and then a water flow is sent to the floor surface by the spraying unit. Thereby, the pollen settled on the floor surface is washed away.

  Moreover, the present invention is characterized in that, in the pollen removing apparatus having the above-described configuration, the air outlet has an outer peripheral part formed in an annular shape and an inner peripheral part arranged inside the outer peripheral part. According to this configuration, the air curtain is formed by the air current blown downward from the outer peripheral portion, and diffusion of ions blown from the inner peripheral portion is suppressed.

  Moreover, the present invention is characterized in that, in the pollen removing apparatus having the above-mentioned configuration, the average particle diameter of the mist sprayed by the spray section is 20 μm to 300 μm. According to this configuration, disappearance due to evaporation of mist is suppressed, and pollen can be reliably settled to the floor surface.

  According to the present invention, the floor includes an ion generator that generates positive ions and negative ions and a spray unit that sprays mist, and the mist adheres to pollen that has been peeled off from the human body by removing static electricity with an air stream containing ions. Therefore, it is possible to prevent the pollen from being dried and reattached due to the disappearance of the mist by evaporation, and to reliably remove the pollen from the human body. In addition, it is not necessary to increase the air volume of the blower fan, so that power can be suppressed and user discomfort can be suppressed.

  Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a schematic view and a perspective view showing the pollen removing apparatus of the first embodiment. The pollen removing apparatus 1 is disposed at an entrance into the room, and is installed, for example, in an entrance hall or the like provided on the outdoor side of the door 2 entering the room from outside. You may arrange | position the pollen removal apparatus 1 in the entrance which enters a room inside a building.

  The pollen removing apparatus 1 includes an air flow sending unit 10 and a spraying unit 20. The airflow delivery unit 10 is covered with a cylindrical housing 11 having a diameter of about 1 m, and is installed on the ceiling surface T of the entrance hall, for example. Thereby, the airflow delivery part 10 is arrange | positioned at the height of about 2 m which becomes above the standing human body H. FIG. The spray unit 20 is covered with a cylindrical housing 21, and is installed concentrically with the airflow delivery unit 10 on the ground surface F of the entrance hall, for example. Thereby, the upper surface 21a (refer FIG. 6) of the housing 21 forms the floor surface of the pollen removal apparatus 1. FIG.

  3 and 4 show a front sectional view and a bottom view of the airflow delivery unit 10. The airflow delivery part 10 opens the suction inlet 12 in the peripheral surface 11a of the housing 11, and opens the blower outlet 13 in the bottom face 11b. As a result, the air duct 14 that connects the suction port 12 and the air outlet 13 is formed in the housing 11.

  The blower outlet 13 has the outer peripheral part 13a distribute | arranged to the outer peripheral side, and the inner peripheral part 13b distribute | arranged to the inner peripheral side. The outer peripheral portion 13a and the inner peripheral portion 13b are formed in an annular shape, and the outer peripheral portion 13a is formed with a diameter wider than the lateral width of the human body H. A human body sensor 17 for detecting the human body H is provided at the center of the bottom surface 11 b of the housing 11.

  A blower fan 15 is disposed in the blower duct 14. A plurality of ion generators 16 are distributed in the circumferential direction on the exhaust side of the blower fan 15. The ion generator 16 generates positive ions and negative ions and discharges them into the air duct 14. By disposing the ion generator 16 on the exhaust side of the blower fan 15, it is possible to prevent the disappearance of ions due to the collision with the blower fan 15.

  5 and 6 show a side sectional view and a top view of the spray section 20. The upper surface 21a of the housing 21 of the spray unit 20 is formed as an inclined surface with a lower central part, and a drain port 27a is opened at the center, and the drain pipe 27 is led out. Further, on the upper surface 21 a of the housing 21, a step board 28 is provided which is a standing position of the human body H formed on a horizontal plane.

  A mist generator 23 for supplying mist from the water supply pipe 22 to generate mist is provided in the housing 21. A plurality of spray ports 24 provided at predetermined intervals on the upper surface 21a of the housing 21 are connected to the mist generating device 23, and mist is sprayed upward from the spray ports 24. The mist generating device 23 is formed by an ultrasonic atomizer or the like, and generates a mist in a state of a fine mist of 10 μm to 100 μm or a fine mist of 100 μm to 300 μm whose average particle diameter is larger than that of the ultrafine mist.

  At this time, when the average particle diameter of the mist is smaller than 20 μm, a so-called dry fog state is obtained, and the mist immediately evaporates to such an extent that the human body H does not get wet. For this reason, as will be described later, if the mist adhering to the pollen evaporates immediately, the pollen may dry and float. Therefore, a mist having an average particle diameter of 20 μm to 300 μm is sprayed by the spraying unit 20, and the pollen to which the mist has adhered is settled to the floor surface. In addition, the average particle diameter of mist can be measured by a Fraunhofer analysis method or the like.

  A water pipe 29 is connected to the mist generator 23 via a valve 25. The water supply pipe 29 diverges radially, and fountain ports 26 are opened on the upper surface 21a of the housing 21 at predetermined intervals in the circumferential direction. By stopping the mist generating device 23 and opening the valve 25, a water flow can be sent out from each fountain port 26.

  FIG. 7 is a block diagram showing the configuration of the pollen removing apparatus 1. The pollen removing apparatus 1 includes a control unit 30 that controls each unit, and an operation switch 32, a human body sensor 17, an ion generating device 16, a blower fan 15, a mist generating device 23, and a valve 25 are connected. Further, a water supply valve, a pump (not shown) and the like for supplying water to the spray unit 20 are connected to the control unit 30. In the control unit 30, a timer 31 is provided for measuring the driving time of the pollen removing device 1.

  FIG. 8 is a flowchart showing the operation of the pollen removing apparatus 1. The operation of the operation switch 32 starts the operation of the pollen removing apparatus 1 and waits until the human body H is detected by the human body sensor 17 in step # 11. When the user stands on the platform 28, the process proceeds to step # 12 by the detection of the human body sensor 17. In step # 12, the blower fan 15 and the ion generator 16 are driven.

As the blower fan 15 and the ion generator 16 are driven, outside air is taken into the blower duct 14 in the housing 11 from the suction port 12 as indicated by an arrow A1 (see FIG. 2). The airflow flowing through the air duct 14 includes positive ions and negative ions generated by the ion generator 16. And the airflow containing the ion N (refer FIG. 1) is sent toward the downward human body H from the blower outlet 13 to arrow A2 (refer FIG. 2). The air supply amount of the blower fan 16 may be about 2 to 5 m ³ / min.

  Static electricity charged on the human body H is removed by the air flow containing the ions N, and pollen P (see FIG. 1) and dust adhering to the human body H are peeled off and guided downward by the air flow. At this time, the airflow sent out from the annular outer peripheral portion 13a forms an air curtain around the human body H, and the airflow is sent out from the inner peripheral portion 13b inside the air curtain. For this reason, the ion N contained in the airflow sent from the inner peripheral part 13b is confined inside the air curtain, and the diffusion of the ion N into the atmosphere can be reduced. Therefore, the static electricity of the human body H can be efficiently removed.

  In addition, it is more desirable to arrange the ion generator 16 on the inner peripheral side than the outer peripheral portion 13a. Thereby, since the number of ions N sent out from the outer peripheral part 13a can be reduced and the number of ions sent out from the inner peripheral part 13b can be increased, the diffusion of the ions N into the atmosphere can be further reduced.

Further, H ₃ O ⁺ (H ₂ O) m (m is 0 or an arbitrary natural number) is generated as a positive ion, and O ₂ — (H ₂ O) n (n is 0 or an arbitrary natural number) as a negative ion. More desirable when it occurs. Thereby, ion adheres to the bacteria and virus in the air, and the effect of sterilization or inactivation can be acquired.

  In step # 13, the valve 25 is closed, and water supply is started in step # 14. In step # 15, the mist generator 23 is driven. Thereby, as shown by the arrow W (refer FIG. 1), mist is sprayed upwards from the spraying opening 24. FIG. The spray amount of mist should just be about 1 L / hr. The mist sprayed from the spray port 24 adheres to pollen P and dust that have been peeled off from the human body H. Since the average particle diameter of the mist is 20 μm to 300 μm as described above, it does not evaporate immediately, so pollen P and dust settle to the floor surface due to the weight of the mist.

  At this time, the spray height of the mist sprayed from the spray port 24 is lower than the height of the lower half of the human body H, and is about 1 m or less. Thereby, the upper half of the human body H is not covered with mist, and the lower half is covered with mist. For this reason, since a user's head does not get wet, a user's discomfort can be prevented.

  In step # 16, it is determined whether or not the human body H is sensed by the human body sensor 17. If the human body H is detected by the human body sensor 17, the process proceeds to step # 17. In step # 17, it is determined whether or not a predetermined time has elapsed by counting the timer 31. If the predetermined time has not elapsed, the process returns to step # 16, and steps # 16 and # 17 are repeated.

  When the user retreats from the pollen removing apparatus 1 and no longer detects the human body H by the human body sensor 17, the process proceeds to step # 18 based on the determination in step # 16. Further, when a predetermined time elapses based on the determination in step # 17, the process proceeds to step # 18. In step # 18, the blower fan 15, the ion generator 16, and the mist generator 23 are stopped.

  In step # 19, the process waits until a predetermined time elapses with the timer 31. During this time, the user recognizes the stop of the blower fan 15 and retreats from the pollen removing device 1 to enter the room. When the predetermined time has elapsed, the valve 25 is opened in step # 20. Thereby, a water flow is sent out from the fountain port 26, and pollen P and dust that have fallen on the upper surface 21a of the housing 21 are washed away. The water flow in which pollen P and dust are washed away flows through the drain pipe 27 via the drain port 27a and is drained.

  In step # 21, the process waits until a predetermined time elapses with the timer 31. When the predetermined time has elapsed, the water supply is stopped in step # 22. Then, the process returns to step # 11 and waits until the human body H is detected.

  According to the present embodiment, pollen P or dust that includes the ion generator 16 that generates positive ions and negative ions and the spray unit 20 that sprays mist, removes static electricity by an air stream containing ions N, and peels off from the human body H. Since the mist adheres to the floor and settles down to the floor surface, it is possible to prevent the pollen P and dust from drying and reattaching due to the disappearance of the mist by evaporation, and to reliably remove the pollen P and dust from the human body H. . In addition, it is not necessary to increase the air volume of the blower fan 15, so that power can be suppressed and user discomfort can be suppressed.

  Moreover, since the blower outlet 13 is disposed above the standing human body H and ions are blown downward from the blower outlet 13, pollen P and dust can be guided downward by the airflow. Further, since the spray port 24 is disposed on the floor surface and the mist is sprayed upward, the time for the mist to fall to the floor surface can be shortened, and evaporation of the mist can be further reduced. Therefore, pollen P and dust can be more reliably settled to the floor surface.

  Moreover, since the spray height of the mist sprayed from the spray port 24 is lower than the height of the lower half of the human body H, the user's head does not get wet, and the user's discomfort can be prevented.

  Moreover, since the spraying part 20 stops spraying mist and sends out a water flow to a floor surface, the pollen P and dust which fell on the floor surface are washed away. Thereby, the reattachment to the human body H of the pollen P and dust which fell on the floor surface can be prevented.

  Moreover, since the blower outlet 13a has the annular outer peripheral part 13a and the inner peripheral part 13b arranged inside the outer peripheral part 13a, the airflow sent from the outer peripheral part 13a forms an air curtain around the human body H. The ions delivered from the inner peripheral portion 13b are confined inside the air curtain. Thereby, diffusion of ions into the atmosphere can be reduced, and static electricity can be efficiently removed.

  Moreover, since the average particle diameter of the mist sprayed by a spray part is 20 micrometers-300 micrometers, pollen P and dust can be easily settled to a floor surface by the mist's own weight suppressing suppression of mist evaporation.

  Next, the pollen removal apparatus 1 of 2nd Embodiment is demonstrated. This embodiment differs in the structure of the spray part 20 with respect to 1st Embodiment shown in above-mentioned FIGS. 9 and 10 show a side view and a top view showing the inside of the spray unit 20. FIG. 11 is a view showing a water supply system of the spray unit 20. For convenience of explanation, in these drawings, the same parts as those in the first embodiment are denoted by the same reference numerals.

  In the housing 21 of the spray unit 20 (see FIG. 5), annular water supply pipes 25 and 42 connected to the water supply pipe 22 via the three-way valve 40 are arranged concentrically. The inner water supply pipe 25 is provided with a plurality of fountain ports 26 protruding upward at predetermined intervals. The outer water supply pipe 42 is provided with a plurality of nozzles 41 protruding upward at a predetermined interval. The nozzle 41 forms a spray port for spraying mist.

  As the nozzle 41, for example, a commercially available product that sprays a mist having a water pressure of 0.15 MPa and an average particle diameter of 80 μm at a spray amount of 8.4 L / hr can be used. Thereby, mist can be easily sprayed, without requiring a pressurization pump.

  The three-way valve 40 rotates in the direction of arrow B when energized, and supplies water from the water supply pipe 22 to the water supply pipe 25 or the water supply pipe 42. That is, when the three-way valve 40 rotates 90 ° from the state in which the water supply pipe 22 and the water supply pipe 25 shown in FIG. 11 are connected, the water supply pipe 22 and the water supply pipes 25 and 42 are switched to a disconnected state. Further, when the three-way valve 40 rotates 90 °, the water supply pipe 22 and the water supply pipe 42 are switched to a connected state.

  Thereby, similarly to 1st Embodiment, the water supply pipe 22 and the water supply pipe 42 are connected, and mist can be sprayed upwards from the nozzle 41 (spraying port). Further, it is possible to connect the water supply pipe 22 and the water supply pipe 25 to send a water flow from the fountain port 26. Therefore, the same effect as the first embodiment can be obtained.

  In the first and second embodiments, the spray unit 20 may be disposed above the human body H, and the mist may be sprayed from above toward the human body H. Further, the air flow sending unit 10 may be arranged on the side of the human body H and send the air flow obliquely downward.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the pollen removal apparatus which is arranged at the entrance to a room | chamber and removes the pollen which adhered to the human body.
