Description

  The present invention relates to an air purification device that removes floating microorganisms such as bacteria and viruses and odor components.

  Water is electrolyzed to produce electrolyzed water, this electrolyzed water is supplied to the filter member, and indoor air is passed through the filter member, thereby floating microorganisms and odor components such as bacteria and viruses floating in the indoor air. An air purifier that removes the above has already been proposed. Conventionally, the structure of this type of air purifier has been as follows.

  That is, a tray, an electrode, an electrolytic cell for electrolyzing water by the electrode, a filter member to which electrolytic water is supplied, and a blower fan that sends room air to the filter member are provided in the housing. In addition, the electrolyzed water generated in the electrolytic cell is supplied to the filter member via the water channel inside the tray. (For example, the following patent document 1).

JP 2014-190553 A

  In such a conventional air purification device, the electrolyzed water generated by the electrode gradually diffuses to the vicinity of the filter member via the water channel, and exhibits the microorganism removal performance by the action of the electrolyzed water that has reached the filter member. .

  The electrolytic cell that generates the electrolytic water needs to limit the substantial capacity of the electrolytic cell in order to generate high-concentration electrolytic water in a short time, and is connected to the filter member through a narrow water channel.

  Since the supply of electrolyzed water from the electrolytic cell to the filter member is due to diffusion in the water through a narrow water channel, the indoor air is rapidly purified when the odor component concentration in the room suddenly increases for some reason. When necessary, it has been required to quickly increase the concentration of electrolyzed water near the filter member.

  Also, when resuming the operation of the air purification device that had been stopped, a pump is used to remove the old electrolyzed water (residing in the tray) that was used for sterilization and deodorization until just before the operation was stopped. Drain the old electrolyzed water near the inner filter member.

  When the old electrolyzed water in the tray is drained, new water (non-electrolyzed water) is supplied from the water supply tank to the tray, and the electrolyzed water concentration in the vicinity of the filter member decreases.

  Therefore, when restarting the operation of the air purification apparatus that has been stopped, it has been required to quickly increase the concentration of the electrolyzed water in the vicinity of the filter member.

  Therefore, the present invention provides an air purification device that quickly increases the concentration of electrolyzed water contained in the filter member by rapidly moving the electrolyzed water generated by the electrode to the filter member, and quickly exerts a sterilization and deodorizing effect. With the goal.

  In order to achieve this object, the present invention includes an electrolytic cell having an electrode therein, a storage tank having a filter member and a drainage unit therein, a tray including the electrolytic cell and the storage tank, A tank and control means, and the control means operates the drainage means for draining the storage tank when the electrolysis by the electrode is completed, so that the electrolysis cell can be electrolyzed by the electrode. The air purification apparatus is characterized in that the electrolyzed water generated therein is supplied to the storage tank having the filter member, thereby achieving the intended purpose.

  According to the present invention, an electrolytic cell having an electrode inside, a storage tank having a filter member and drainage means therein, a tray including the electrolytic cell and the storage tank, a drainage tank, and a control means, The control means, when the electrolysis by the electrode is completed, by operating the drain means for draining the storage tank, the electrolyzed water generated in the previous electrolytic cell by the electrolysis by the electrode, Since the air purification device is configured to supply the storage tank having the filter member, when the air needs to be rapidly purified, or the air purification device that has been stopped is restarted. Since the water in the storage tank is reduced by the drainage performed when the electrolysis is finished, the electrolytic water in the electrolytic tank is quickly supplied to the storage tank having the filter member. Electrolytic water concentration in Tomeso will reduce the time to reach the target density, rapidly it is possible to obtain an effect of providing an air purification device which can exhibit a sterilization deodorizing effect.

  The air purification device according to claim 1 of the present invention includes a water supply tank, a tray, an electrolytic cell, an electrode, a storage tank, a filter member, a drainage unit, a drainage tank, and a control unit. When the electrolysis by the electrode is completed and the drain tank is not full, the control means operates the drain means for draining the storage tank so that the electrolysis by the electrode can be performed in the previous electrolytic cell. The electrolyzed water produced in the step is supplied to the storage tank having the filter member. As a result, by draining the electrolyzed water in the tray, the electrolyzed water in the communicating electrolyzer is immediately moved to the filter member, so that the electrolyzed water concentration in the filter member and the tray quickly reaches the target concentration. The effect that the sterilization deodorizing effect can be enhanced is achieved.

  Further, the drainage tank may be provided with a full water detection means, and the drainage means may be operated when the full water detection means does not detect full water. As a result, the initial drainage detection means detects drainage in the tray after the operation starts, and the full water detection means detects a full water state during drainage for supplying electrolytic water to the filter member. In the operation after the drain tank is installed, drainage is surely performed, the dirty electrolyzed water in the tray is removed, and new electrolyzed water generated by electrolysis is quickly supplied to the filter member, thereby eliminating the sterilization and deodorization. The effect can be further enhanced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, the air purification apparatus of this Embodiment is equipped with the main body case 1, the suction port 2 which sucks indoor air in the side surface, the blower outlet 3 which blows off the purified air on the top surface, the inside Is provided with an air air passage 4 communicating with the air outlet 2 through the air outlet 3. In addition, in the main body case 1, a blowing unit 5 and a filter member 6 are provided for flowing air through the air air passage 4 from the suction port 2 toward the blowout port 3. The filter member 6 has a rotatable hollow cylindrical shape having a plurality of openings on the surface thereof, and is provided so that the surface of the filter member 6 blocks the air air passage 4.

  The air blowing means 5 is provided as an upper part of the main body case 1 and is formed as a so-called sirocco fan including a motor, an impeller rotated by the motor, and a case surrounding them.

  Further, a water supply tank 7, a drain tank 8 and a tray 9 are provided at the lower part of the main body case 1, and these can be detached from the main body case 1. In the tray 9, an electrolytic cell 11 having an electrode 10 and a storage tank 13 having a filter member 6 and a drainage means 12 are provided. Inside the storage tank 13, the lower part of the filter member 6 is immersed in the electrolyzed water. The drainage means 12 is connected by piping so that the electrolyzed water inside the storage tank 13 is discharged to the drainage tank 8. Here, a pump is used as the drainage means in the present embodiment. Moreover, in order to produce | generate high concentration electrolyzed water in a short time, since the electrolytic cell 11 needs to restrict | limit a capacity | capacitance and it is also necessary to prevent the excessive backflow from a storage tank, the electrolytic cell 11 and the storage tank 13 are lower parts. The partition plate 14 having a gap between the electrolytic cell 11 and the storage tank 13 restricts free movement of water. The drainage tank 8 is provided with initial drainage detection means 15 and full water detection means 16. A control means 17 is provided in the main body case 1, and the operation of the drainage means 12 is controlled by processing the signal output of the initial drainage detection means 15, the full water detection means 16 and the control means 17.

  Next, FIG. 2 shows the appearance of the air purification device. As described above in the description of FIG. 1, the main body case 1 is substantially box-shaped, the suction holes 2 having a substantially rectangular shape are provided on both side surfaces of the main body case 1, and the top surface of the main body case 1 is A substantially rectangular air outlet 3 is provided. The room air sucked into the air purification device from the suction port 2 is sterilized and deodorized and blown out into the room again from the outlet 3.

  FIGS. 3A, 3B, and 3C are side sectional views of the drainage tank 8 showing an example of drainage detection that changes with the water level. The drainage tank 8 is provided with initial drainage detection means 15 and full water detection means 16. In the present embodiment, the initial drainage detection means 15 and the full water detection means 16 use float switches using magnetic sensors. When the water level inside the drainage tank rises, a magnetic sensor provided on the side surface of the drainage tank detects a change in the inclination of the float switch that changes due to buoyancy, thereby detecting the rise in the water level inside the drainage tank. In the embodiment of the present invention, as shown in FIG. 3 (b), the initial drainage detection means 15 provided in the drainage tank 8 raises the water level in the drainage tank 8 due to drainage from the storage tank when the operation of the main body starts. As shown in FIG. 3 (c), the full water detection means 16 detects the full water in the drain tank 8 and transmits it to the control means 17. As shown in FIG. 3 (a), before the start / restart of operation, the user removes the drain tank 8 and drains the water inside the drain tank. 15. Both the full water detection means 16 do not detect. Subsequently, immediately after the start / restart of operation, drainage in the storage tank 13 is performed, and when an amount equivalent to the storage capacity of the storage tank 13 is drained, the initial drainage detection means 15 detects as shown in FIG. The control means 17 stops the drainage means 12. Thereafter, periodic electrolysis and drainage are repeated, and when the drainage tank 8 eventually becomes full, the full water detection means 16 detects full water as shown in FIG. Will not work. The operation of discharging an amount equivalent to the water storage capacity of the storage tank 13 immediately after the start / resumption of operation is defined as initial drainage.

  The purpose of the initial drainage is to discharge the old electrolyzed water that has already stayed in the storage tank 13 before the start / restart of operation (the effect of sterilization and deodorization is reduced by contact with room air). Therefore, the initial drainage detection means 15 which is a float switch directly discharges the old electrolyzed water by directly detecting the drainage amount equal to the water storage capacity of the storage tank 13 regardless of the flow rate and operation time of the drainage means 12. Completion can be reliably detected.

  Subsequently, the main operation of the portion according to the embodiment of the present invention in the operation of the air purification device will be described.

  FIG. 4 shows the signal output state of each detecting means in operation and the operation states of the electrode 10 and the drainage means 12. When the operation of the main body is started, first, the drainage means 12 is operated, the initial drainage is performed, the old electrolyzed water in the storage tank 13 is drained, and new water is supplied from the water supply tank 7. In this way, when resuming the operation of the air purification device, drainage for removing old electrolyzed water that has been used for sterilization and deodorization until just before the operation is stopped and has reduced the sterilization and deodorization effect due to contact with room air. Use initial drainage. When the initial drainage is detected by the initial drainage detection means 15 by the initial drainage, the control means 17 stops the operation of the drainage means 12 and the initial drainage is finished. Next, the control means 17 starts electrolysis by the electrode 10, and high concentration electrolyzed water is generated in the electrolytic cell 11. Further, after the electrolysis is completed, the control means 17 again drains a part of the water in the storage tank 13 by the drainage means 12. Along with this, the electrolyzed water in the electrolytic cell 11 flows into the storage tank 13.

  Thereby, the filter member 6 will absorb electrolyzed water in the storage tank 13. Next, the control means 17 starts air blowing and passes room air through the filter member that has absorbed the electrolyzed water, so that bacteria and odor components are removed from the air by the electrolyzed water.

  In this embodiment, the water in the storage tank 13 is reduced by the drainage after the end of the electrolysis, and the corresponding electrolyzed water is supplied from the inside of the electrolysis tank, so that a quick sterilization and deodorizing effect can be obtained. Bring.

  In the present embodiment, a partition plate is used for separating and connecting the electrolytic cell 11 and the storage tank 13, but the partition plate is not necessarily required, and a reverse flow from the storage tank 13 to the electrolytic cell 11 is prevented. As long as it is possible to restrict the movement of water more than necessary for the purpose of suppression, the water may be separated and connected by other means such as a thin pipe. Any structure may be used as long as the structure is supplied.

  In addition, the capacity of the drain tank 8 may be equal to or greater than the combined capacity of the old electrolyzed water that has already accumulated in the storage tank 13 before the start / restart of operation and the capacity equivalent to the electrolytic tank 11, The effect of this embodiment can be obtained as long as the capacity can accommodate the old electrolyzed water drained at the time of initial drainage and the drainage after completion of electrolysis.

  Moreover, although the drainage means 12 in this Embodiment is using the pump, since it should just be a mechanism in which the drainage from the storage tank 13 is possible, the structure is not specifically limited, For example, in the storage tank lower part A mechanism that attaches a valve and opens and closes the valve as necessary may be used.

  In addition, although the initial drainage detection means 15 and the full water detection means 16 in the present embodiment use a float switch, the means for reliably detecting the fluctuation of the water level inside the drainage tank regardless of the operation state of the drainage means. Any other means may be used.

  The air purifying apparatus according to the present invention is capable of quickly and surely supplying the electrolyzed water generated by the electrodes to the filter member so as to exert a quick sterilization and deodorizing effect when the operation is resumed. Therefore, it is useful as a quick air purification means in a space where the odor concentration fluctuates, such as a care facility.
