First top supplied to And a first downstream supply water channel connecting the first upstream supply water channel and the electrode water channel, and the bottom surface of the first downstream supply water channel is defined by the first upstream supply water channel. The bottom surface of the electrode water channel is lower than the bottom surface of the first downstream supply water channel, and the bottom surface of the second supply water channel is from the bottom surfaces of the first downstream supply water channel and the electrode water channel.

  The air purifier according to claim 1 of the present invention forms a detachable water supply tank, a filter member to which water in the water supply tank is supplied, and a supply water channel for guiding the water in the water supply tank to the filter member. Air cleaner equipped with a tray, an electrode unit for electrolyzing water in the supply channel, a pump for pumping up sewage containing scale remaining in the tray, and a drainage tank for storing sewage pumped up by the pump The supply water channel is a first supply water channel located below the water supply tank, a second supply water channel located below the filter member, and a reservoir connected to the outlet side of the second supply water channel. And an electrode water channel that is connected to the outlet side of the first supply water channel and connected to the inlet side of the second supply water channel. The first supply water channel is the first to which the water in the water supply tank is first supplied. Upstream supply water And a first downstream supply water channel connecting the first upstream supply water channel and the electrode water channel, the bottom surface of the first downstream supply water channel is lower than the bottom surface of the first upstream supply water channel, The bottom surface of the electrode water channel is lower than the bottom surface of the first downstream supply water channel, and the bottom surface of the second supply water channel is higher than the bottom surfaces of the first downstream supply water channel and the electrode water channel.

  As a result, the electrolyzed water generated by the electrode unit in the electrolyzing water channel rides the flow of water supplied to the filter member from the first supply water channel through the electrolyzing water channel and the second supply water channel to the filter member. In particular, in the electrolysis water channel, the electrolyzed water in the electrolysis water channel is heated by electrolysis, so that heat convection is generated. Therefore, the water discharged from the water supply tank passes through the first upstream supply water channel. The flow is stabilized once stored in the first downstream supply channel, and the electrolyzed water that flows into the lower part of the electrode from the temperature difference due to the electrolysis by the electrode unit and the water in the water supply tank is electrolyzed is electrolyzed. Since it is warmed together with the decomposition, is transported to the upper part of the electrolysis water channel by heat convection, and is transported to the inlet side of the second supply water channel, the electrolyzed water generated by the electrode in the electrode water channel is surely filtered. An effect that can be delivered to the data member.

  The lower end of the electrode unit may be positioned between the bottom surface of the first downstream supply water channel and the bottom surface of the electrode water channel.

  As a result, when the water coming out of the water supply tank accumulated in the first downstream supply water channel flows into the electrode water channel along the bottom surface of the first downstream supply water channel, it is not between the lower portions of the electrode unit but between the electrodes. Since it passes through, the electrolyzed water generated in the vicinity of the electrode plate can be made to flow toward the outlet of the electrode water channel, so that the electrolyzed water can be reliably conveyed to the filter member located above the second supply water channel. There is an effect that can be done.

  The bottom surface of the second supply water channel has an inclined surface that is inclined downward as it goes from the second supply water channel to the electrode water channel, and this inclined surface has a wall higher than the bottom surface of the second supply water channel, You may make it the structure bent in the shape.

  By having the inclined surface, the cold water coming out of the supply tank becomes difficult to flow into the second supply water channel, is warmed by electrolysis, and the electrolytic water existing above the electrolysis water channel passes through the inclined surface, In addition to the effect of being easily transported to the filter member located above the supply channel, the electrolyzed water transported to the second supply channel is blocked by a wall higher than the bottom surface of the second supply channel, and the inclined surface It is possible to suppress backflow to the electrode water channel over the wall without being along, and because of the crank shape, the electrolyzed water that tries to flow back from the downstream side of the inclined surface also collides with the side surface of the inclined surface at the corner Thus, there is an effect that it is possible to suppress backflow into the electrolysis water channel.

  Moreover, the electricity supply method to an electrode unit is good also as an intermittent operation.

  As a result, the electrolyzed water that is generated during energization and partially leaks above the first downstream supply water channel is cooled by providing the energization stop time, and is supplied to the filter member together with water newly supplied from the water supply tank. Since it is transported, there is an effect of preventing the electrolyzed water from staying in the electrolysis water channel.

  In the control means 94, when the opening / closing detection means 91 does not detect the closed state of the opening / closing door 11 in Step 1, the operation of the pump 70 is not performed.

  In step 1, when the open / close detection means 91 detects the closed state of the open / close door 11, the water supply detection means 92 attaches the water supply tank 20 (step 2), detects that there is water (step 3), and When the drainage tank 30 is mounted by the drainage detection means 93 (step 4) and it is detected that there is no sewage (less than a predetermined amount) in the drainage tank 30 (step 5), the pump 70 is operated. (Step 6).

  In the control means 94, the open / close detection means 91 detects the open state of the open / close door 11 (step 1), the water supply detection means 92 detects the absence of the water supply tank 20 (step 2), and the water absence detection (step) 3) When either the detection of the absence of the drainage tank 30 by the drainage detection means 93 (step 4) or the detection of full sewage (exceeding a predetermined amount) in the drainage tank 30 (step 5) is performed.

  In addition, although the present Example demonstrated the case where the opening / closing detection means 91 which detects the opening / closing state of the door 11 was provided, the opening / closing detection means 91 does not need to be provided.

  The greatest feature of the present embodiment is the shape of the supply water channel 42 of the tray 40 as shown in FIGS.

  Specifically, the supply water channel 42 includes a first supply water channel 42a located below the water supply tank 20, a second supply water channel 42b located below the filter member 60, and a second supply water channel 42b. The reservoir 42c is connected to the outlet side, and the electrode water channel 42d is connected to the outlet side of the first supply water channel 42a and is connected to the inlet side of the second supply water channel 42b. An electrode unit 50 is disposed in the electrode water channel 42d.

  A first upstream supply channel 42e through which the water in the water supply tank is first supplied to the first supply channel 42a, and a first downstream side connecting the first upstream supply channel 42e and the electrode channel 42d. 42f, and the bottom surface of the second supply channel 42b includes an inclined surface 42g that is inclined downward from the second supply channel 42b toward the electrode channel 42d.

  The bottom surface of the first downstream supply water channel 42f is lower than the bottom surface of the first upstream supply water channel 42e, and the bottom surface of the electrode water channel 42d is lower than the bottom surface of the first downstream supply water channel 42f. The bottom surface of the water channel 42b is higher than the bottom surfaces of the first downstream supply water channel 42f and the electrode water channel 42d.

  Thus, the electrolyzed water generated by the electrode unit 50 in the electrode water channel 42d is the water that the water in the water supply tank 20 supplies to the filter member 60 from the first supply water channel 42a through the electrode water channel 42d and the second supply water channel 42b. Is supplied to the filter member 60.

  In particular, in the vicinity of the electrode water channel 42d, the electrolyzed water in the electrode water channel 42d is heated by electrolysis, so that heat convection is generated. Therefore, the water discharged from the water supply tank 20 passes through the first upstream supply water channel 42e. The flow is stabilized once stored in the first downstream supply water channel 42f, and flows into the lower part of the electrode from the temperature difference caused by the electrolysis by the electrode unit 50, and the water in the water supply tank 20 is electrolyzed. The water is warmed together with the electrolysis, and is transported to the upper part of the electrode water channel 42d by thermal convection, and is transported to the inlet side of the second supply water channel 42b.

  At this time, by having an inclined surface 42g between the electrode water channel 42d and the second supply water channel 42b, the cold water flowing out from the water supply tank 20 flowing into the lower part of the electrode flows into the second supply water channel 42b. Since it becomes difficult, the electrolyzed water produced | generated by the electrode in 42 d of electrode water paths can be reliably conveyed to the filter member 60. FIG.

  Further, the inclined surface 42g has a wall 42h higher than the bottom surface of the second supply water channel 42b and is bent into a crank shape, so that the electrolyzed water once transported to the second supply water channel 42b is the second supply water channel 42b. The wall 42h higher than the bottom surface and the shape of the crank block prevent it from flowing along the inclined surface, over the wall, and back to the electrode water channel. It is possible to suppress backflow into the electrode water channel 42d by hitting the side surface of the electrode.

  The lower end of the electrode unit 50 is located between the bottom surface of the first downstream supply water channel 42f and the bottom surface of the electrode water channel 42d.

  For this reason, when the water discharged from the water supply tank 20 accumulated in the first downstream supply water channel 42f flows into the electrode water channel 42d along the bottom surface of the first downstream supply water channel 42f, Therefore, the electrolyzed water generated in the vicinity of the electrode plate can flow toward the outlet of the electrode water channel 42d, so that the electrolyzed water is reliably positioned above the second supply water channel 42b. It can be transported to the filter member 60.

  Moreover, the electricity supply method to the electrode unit 50 is an intermittent operation as shown in FIG. 20, for example.

  As a result, the electrolyzed water generated during energization and partially leaking above the first downstream supply water channel 42f is cooled by providing the energization stop time, and is filtered together with the water newly supplied from the water supply tank 20. Since it is conveyed to the member, it is possible to prevent the electrolytic water from staying in the electrode water channel 42d.

  The present invention is an air cleaning device that removes microorganisms floating in the space, but is also suitable as a humidifier having a function of removing floating microorganisms.
