JP, 2014-190553, A

In such a conventional air purifier, electrolyzed water generated by the electrodes 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 reaching the filter member. ..

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

The supply of electrolyzed water from the electrolyzer to the filter member is due to diffusion in water through a narrow channel, so the indoor air can be rapidly purified if the odorous component concentration in the room suddenly increases for any reason. It has been demanded that the concentration of electrolyzed water in the vicinity of the filter member be rapidly increased when necessary.

In addition, when restarting the operation of the air purifier that had been stopped, the pump is used to remove the old electrolyzed water (remaining in the tray) that was used for disinfecting and deodorizing until just before stopping the operation. The old electrolyzed water in the vicinity of the filter member inside is drained.

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 near the filter member decreases.

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

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

Then, in order to achieve this object, the present invention provides an electrolytic cell having an electrode therein, a storage tank having a filter member and drainage means therein, a tray including the electrolytic cell and the storage tank, and drainage. A tank and a control unit are provided, and the control unit operates the drainage unit for draining water in the storage tank when the electrolysis by the electrode is completed, thereby performing the electrolysis by the electrode. The air purifying device is characterized in that the electrolyzed water generated in the electrolyzer is supplied to the storage tank having the filter member, thereby achieving the intended purpose.

According to the present invention, an electrolysis tank having an electrode inside, a storage tank having a filter member and drainage means inside, a tray provided with the electrolysis tank and the storage tank, a drainage tank, and a control means. Having the control means, when the electrolysis by the electrode is completed, by operating the drainage means for draining the water in the storage tank, electrolysis generated in the electrolysis tank by the electrolysis by the electrode When water is supplied to the storage tank having the filter member, it is necessary to rapidly purify the air, or to restart the operation of the air purifying device that has been stopped. The water in the storage tank is reduced by the drainage performed when the process is completed, and the electrolyzed water in the electrolysis tank is quickly supplied to the storage tank having the filter member. It is possible to obtain the effect of providing an air purifying apparatus that can shorten the time required to reach the air conditioner and rapidly exhibit the disinfecting and deodorizing effect.

And a control means, wherein the control means operates the drainage means for draining the water in the storage tank when the electrolysis by the electrode is completed, thereby performing the electrolysis by the electrode. The electrolytic water generated in the electrolytic bath is supplied to the storage tank having the filter member. With this, 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 concentration of electrolyzed water in the filter member and the tray quickly reaches the target concentration.

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

(Embodiment 1)
As shown in FIG. 1, the air purifying apparatus of the present embodiment includes a main body case 1, a side surface of which has a suction port 2 for sucking indoor air, and a ceiling surface having a blowout port 3 for blowing purified air. An air flow path 4 is provided in the air passage 4, which connects the suction port 2 to the air outlet 3. In addition, inside the main body case 1, a blower means 5 for flowing air from the suction port 2 to the blowout port 3 in the air flow path 4 and a filter member 6 are provided. The filter member 6 has a rotatable hollow cylindrical shape having a plurality of openings on its surface, and the surface of the filter member 6 is provided so as to block the air passage 4.

The blower unit 5 is provided on the upper portion of the main body case 1 and is formed as a so-called sirocco fan including a motor, an impeller rotating by the motor, and a case surrounding the motor and the impeller.

A water supply tank 7, a drainage tank 8 and a tray 9 are provided below the main body case 1, and these can be removed from the main body case 1. An electrolyzer 11 having an electrode 10 and a reservoir 13 having a filter member 6 and a drainage means 12 are provided in the tray 9. Inside the storage tank 13, the lower part of the filter member 6 is immersed in electrolyzed water. The drainage means 12 is connected by a pipe 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. In addition, since the electrolytic tank 11 needs to have a limited capacity in order to generate high-concentration electrolyzed water in a short time, and it is also necessary to prevent excessive backflow from the storage tank, the electrolytic tank 11 and the storage tank 13 have a lower portion. It is divided by a partition plate 14 having a gap in between to limit free movement of water between the electrolytic bath 11 and the storage bath 13. Further, the drainage tank 8 is provided with an initial drainage detecting means 15 and a full water detecting 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 outputs 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 purifying device. As described above in the description of FIG. 1, the main body case 1 has a substantially box shape, the substantially square suction ports 2 are provided on both side surfaces of the main body case 1, and the top surface of the main body case 1 has A substantially quadrangular outlet 3 is provided. The room air sucked into the air purifying device from the suction port 2 is deodorized by sterilization, and is blown into the room again from the air outlet 3.

3A, 3B, and 3C are side cross-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 detecting means 15 and the full water detecting means 16 use a float switch using a magnetic sensor. 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 water level rise 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 the drainage from the storage tank when the operation of the main body is started. Then, as shown in FIG. 3C, 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. 3A, before the operation is started/restarted, the user removes the drainage tank 8 to drain the water inside the drainage tank. Neither 15 nor the full water detection means 16 detects. Subsequently, immediately after the operation is started/restarted, the 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. 3B. Then, the control means 17 stops the drainage means 12. Thereafter, periodic electrolysis and drainage are repeated, and when the drainage tank 8 is finally filled up, the fullness detection means 16 detects fullness as shown in FIG. 3C, and thereafter, the control means 17 causes the drainage means 12 to reach fullness. Stop working. The operation of discharging the same amount of water as the storage capacity of the storage tank 13 immediately after the start/restart of operation is referred to as initial drainage.

The purpose of the initial drainage is to discharge the old electrolyzed water that has already accumulated in the storage tank 13 before the operation is started/restarted (the disinfecting and deodorizing effect is reduced by contact with the indoor air). Therefore, the initial drainage detecting means 15 which is a float switch directly detects the discharge amount of the same amount of water as the storage capacity of the storage tank 13 regardless of the flow rate of the draining means 12 and the operating time, thereby discharging the old electrolyzed water. The completion can be reliably detected.

Subsequently, among the operations of the air purifying apparatus, the main operations of the portions according to the embodiment of the present invention will be described.

FIG. 4 shows a signal output state of each detecting means and an operating state of the electrode 10 and the drainage means 12 during operation. When the operation of the main body is started, first, the drainage means 12 is activated to perform initial drainage, drain the old electrolyzed water in the storage tank 13, and supply new water from the water supply tank 7. In this way, when restarting the operation of the air purifier, the waste water used to remove old electrolyzed water that has been used for sanitizing and deodorizing until just before the operation is stopped and has been in contact with indoor air and has a reduced sanitizing and deodorizing effect is removed. Initial drainage. When the initial drainage detecting means 15 detects the rise of the water level in the drainage tank due to the initial drainage, the control means 17 stops the operation of the drainage means 12, and the initial drainage is ended. Next, the control means 17 starts electrolysis by the electrode 10 and high concentration electrolyzed water is generated in the electrolyzer 11. Further, after the electrolysis is finished, the control means 17 causes the draining means 12 to drain a part of the water in the storage tank 13 again. Along with this, the electrolyzed water in the electrolysis tank 11 flows into the storage tank 13.

As a result, the filter member 6 absorbs the electrolyzed water in the storage tank 13. Next, the control means 17 starts blowing air and causes room air to pass through the filter member that has absorbed the electrolyzed water, whereby the electrolyzed water removes bacteria and odorous components from the air.

In the present embodiment, the drainage after completion of this electrolysis reduces the amount of water in the storage tank 13, and the electrolyzed water corresponding to that amount is supplied from the inside of the electrolysis tank, thereby providing a rapid disinfection deodorizing effect. Bring

In the present embodiment, a partition plate is used to separate and connect the electrolytic tank 11 and the storage tank 13. However, the partition plate is not necessarily a partition plate, and reverse flow from the storage tank 13 to the electrolytic tank 11 is not necessary. If it is possible to limit excessive movement of water for the purpose of suppressing it, the water may be separated and connected by other means such as a thin pipe, and the drainage means 12 operates to move the electrolytic water from the electrolytic tank 11 to the storage tank 13. Any structure that supplies

Further, the capacity of the drainage tank 8 may be equal to or larger than the combined capacity of the capacity of the old electrolyzed water that has already accumulated inside the storage tank 13 before the start/restart of operation and the capacity equivalent to that of the electrolysis tank 11, The effect of the present embodiment can be obtained as long as the capacity is large enough to accommodate old electrolyzed water drained during initial drainage and drainage after electrolysis.

Further, although the pump is used as the drainage means 12 in the present embodiment, the structure is not particularly limited as long as it is a mechanism capable of draining water from the storage tank 13, and, for example, in the lower portion of the storage tank. A mechanism that attaches the 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 the float switch, a means for surely detecting the fluctuation of the water level inside the drainage tank regardless of the operating state of the drainage means. If so, other means may be used.

The air purification apparatus according to the present invention, by rapidly and reliably supplying the electrolyzed water generated by the electrode to the filter member, it is possible to exert a rapid sterilization deodorizing effect when restarting the operation. Therefore, it is useful as a quick air purifying means in a space such as a nursing facility where the odor concentration fluctuates.
