In the air passage 13, an air cleaner 3 (water storage container, filter portion), a fan 2, and an air outlet 8 are provided in this order from the air inlet 7. When the fan unit 15 is rotated by the motor unit 14 of the fan 2, the air outside that enters the main body casing 1 through the air inlet 7 is blown out of the main body casing 1 through the air cleaning unit 3 (water storage container, filter unit), the fan 2, and the air outlet 8 in this order.

The fan 2 includes: a motor unit 14 provided at the center of the main body case; a fan unit 15 rotated by the motor unit 14, and a scroll-shaped casing 16 surrounding the fan unit and the casing.

The motor portion 14 is fixed to the case portion 16.

The fan unit 15 is a sirocco fan and is fixed to a rotating shaft (not shown) extending in the horizontal direction from the motor unit 14. The rotation shaft of the motor unit 14 extends from the front surface side to the rear surface side of the main body case 1.

The casing 16 is provided with a discharge port 17 and an intake port 18. The discharge port 17 is provided on the upper surface side of the main body case 1 of the case portion 16. The suction port 18 is provided on the front surface side of the main body case 1 of the case portion 16. When the fan portion 15 is rotated by the motor portion 14, air is sucked into the case portion 16 through the suction port 18 of the case portion 16, and the sucked air is blown out of the case portion 16 through the discharge port 17.

The air purifying portion 3 includes a water storage container 19, a tank member 20, a filter portion 21, and an electrolytic unit 22.

The water storage container 19 is formed in a box shape having an opening in the top surface, and is configured to store water. The water storage tank 19 is disposed in the hollow portion 12 at the lower portion of the main body case 1, and is slidable in the horizontal direction so as to be attachable to and detachable from the main body case 1. The water storage tank 19 stores water supplied from the tank member 20. Water includes fresh water and brine. A water level detection unit 25 is provided in the water storage tank 19.

The water level detection part 25 includes: a floating portion 25a provided in the water storage container 19 so as to be freely movable, and movable together with the water level; and a position detection portion 25b (refer to fig. 3, 5) that detects the position of the floating portion 25 a. The floating portion 25a is made of foamed styrene containing a magnet and is attached to the water storage container 19 so as to be movable in the vertical direction. An example of the position detecting section 25b is a hall sensor fixed to the main body case 1 and detecting a magnetic field of the magnet.

The tank member 20 is configured to be attachable to and detachable from a water storage tank 19 provided at a lower portion inside the main body case 1. The tank member 20 is attached to a tank holding portion 23 provided on the bottom surface of the water storage tank 19. The tank member 20 includes a tank 20a for storing water and a cover 20b provided at an opening (not shown) of the tank 20 a. An opening/closing portion (not shown) is provided in the center of the lid 20b, and when the opening/closing portion is opened, water in the tank 20a is supplied to the water storage tank 19. Specifically, when the opening of the tank 20a is directed downward and the tank member 20 is attached to the tank holding portion 23 of the water storage container 19, the opening/closing portion is opened by the tank holding portion 23. That is, when water is put into the tank member 20 and attached to the tank holding portion 23, the opening/closing portion is opened to supply water from the tank member 20 to the water storage container 19, and water is stored in the water storage container 19. When the water level in the water storage tank 19 rises and the water reaches the lid 20b, the opening of the tank member 20 is closed by the water, and therefore, the water supply is stopped. The water remains in the tank member 20, and the water in the tank 20a is supplied to the water storage tank 19 every time the water level in the water storage tank 19 drops. That is, the water level in the water storage tank 19 can be kept constant.

The filter portion 21 is a member that brings water stored in the water storage tank 19 into contact with indoor air drawn into the main body case 1 by the fan 2. The filter portion 21 has a filter 24 formed in a cylindrical shape, and holes through which air can flow are circumferentially arranged. The filter portion 21 is housed in the water storage container 19 so that one end of the filter 24 is immersed in the water storage container 19 and is rotatable about the central axis of the filter 24. The filter portion 21 is configured to be rotated by a driving unit described later so that water continuously contacts indoor air.

The electrolysis unit 22 is provided in the main body casing 1 so as to be movable in the vertical direction. In FIG. 2, the electrolytic cell 22 is not visible because it has moved upward. In FIG. 3, the electrolysis unit 22 is moved downward. The electrolysis unit 22 includes a 1 st electrode (not shown) and a 2 nd electrode (not shown). The water storage container 19 is installed in the hollow portion 12 of the lower portion of the main body case 1. When the electrolysis unit 22 moves downward, the 1 st electrode and the 2 nd electrode are immersed in the water storage container 19 (see fig. 3). A voltage is applied to the 1 st electrode and the 2 nd electrode in a state where the 1 st electrode and the 2 nd electrode are immersed in the water storage container 19. This voltage electrochemically treats the water in the water reservoir 19. The water in the water storage tank 19 contains an electrolysis accelerator to be put in by the user. An example of the electrolysis-promoting solvent is an aqueous sodium chloride solution. The aqueous sodium chloride solution is mixed with water in the water storage container 19 to be diluted. Hypochlorous acid is generated from the diluted sodium chloride aqueous solution by the electrolysis unit 22. The electrolysis unit 22 is configured to be attachable to and detachable from the main body case 1.

Fig. 6 is a diagram showing functional blocks of an air cleaner according to embodiment 1 of the present invention.

As shown in fig. 6, the control section 4 controls the electrolysis unit 22, the filter section 21 (driving section 21a), the fan 2 (motor section 14), and an operation lamp 27 described later. Specifically, the control unit 4 applies a voltage to the 1 st electrode and the 2 nd electrode in the electrolysis unit 22 based on a signal from the water level detection unit 25 and an operation of the operation button 26, and controls the operation of the drive unit 21a in the filter unit 21, the rotation speed of the fan unit 15 in the fan 2, the turning on, turning off, and the like of the operation lamp 27.

Fig. 7 is a view of the operation unit as viewed from above.

The operation portion 5 is provided on the front side of the top surface of the main body case 1. As shown in fig. 7, the operation unit 5 includes a plurality of operation buttons 26 and operation lamps 27.

The operation buttons 26 include an operation mode button 26a and a power button 26 b. An operation mode button 26a is provided on the slightly right side of the center portion when viewed from the front surface side of the main body case 1, and a power supply button 26b is disposed on the right end. The operation mode button 26a and the power button 26b are arranged in a row in the left-right direction of the main body case 1. The power button 26b is pressed by the user to instruct the control unit 4 to start the operation of the electrolysis unit 22 and the fan 2. Then, the power button 26b receives the next pressing by the user, and instructs the control unit 4 to stop the operation of the electrolysis unit 22 and the fan 2.

The operation lamp 27 includes a mode lamp 27a and a power supply lamp 27 b.

The number of the mode lamps 27a is 3 on the back surface side of the main body case 1 of the operation mode button 26 a. The 3 lamps are arranged in a row in the left-right direction of the main body housing 1, the left end is in a strong mode, the center is in a medium mode, and the right end is in a weak mode. An example of the mode lamp 27a is a Light emitting Diode (hereinafter, referred to as LED), and the LED is turned on or off by the control of the control unit 4. In the case of the strong mode, the LED at the left end is lit. In the case of the medium mode, the central LED is lit. In the weak mode, the LED at the right end is lit.

Fig. 8 is a view of the display section viewed from the front side of the main body case 1.

As shown in fig. 8, the display section 6 is provided in the main body case 1, which is an upper front side of the main body case 1. The user can see from the outside of the main body case 1 through the window portion 11 of the panel 10 of the main body case 1. The display portion 6 includes a water supply lamp 6a and a maintenance lamp 6 b.

The water supply lamp 6a is disposed in the center of the display unit 6 when viewed from the front surface side of the main body housing 1. An example of the water supply lamp 6a is an LED, and the LED is turned on or off by the control of the control unit 4.

The maintenance lamp 6b as a maintenance instruction portion is disposed adjacent to the left side of the water supply lamp 6a when viewed from the front surface side of the main body housing 1. An example of the maintenance lamp 6b is an LED, and the LED is turned on or off under the control of the control unit 4.

As shown in fig. 3, 4, 6, 7, and 8, the present embodiment is characterized by a control unit 4. The control unit 4 measures and stores an operation time since the user has mounted the tank member 20 on the water storage container 19, an instruction to start the operation of the electrolysis unit 22 and the fan 2 is given to the control unit 4 from the power button 26b, which is one of the operation buttons 26, and the fan 2 is operated from the time when the water level detection unit 25 detects the supply of water into the water storage container 19 from the tank member 20. After the user mounts the tank member 20 containing water in the water storage tank 19 and starts the operation of the air cleaning apparatus, the operation of the air cleaning apparatus may be stopped and the power plug 28 may be removed from the external power supply. There are cases where the user further connects the power plug 28 to the same power supply as the just-previous external power supply or a different external power supply, where the operation of the air cleaning device is started. In this case, the control unit 4 determines whether the operation time is the same as or shorter than the predetermined time. The control unit 4 urges the user to discharge the water in the water storage tank 19 when the operation time is longer than the predetermined time, and starts the operation of the electrolysis unit 22 and the fan 2 when the operation time is the same as or shorter than the predetermined time. This can reduce unnecessary drainage work.

Specifically, the user may change the location of the air purification apparatus after starting the operation of the air purification apparatus by putting water into the tank member 20. In such a case, first, the user stops the operation of the air cleaning device and removes the power plug 28 from the external power source. Next, the user moves the place of the air cleaning apparatus, connects the power plug 28 to the same or different external power supply as the previous external power supply again, and then instructs the control unit 4 to start the operation of the electrolysis unit 22 and the fan 2 by the operation of the power button 26b, which is one of the operation buttons 26, to start the operation of the air cleaning apparatus.

As described above, when the tank member 20 is mounted on the water storage container 19, the water in the tank member 20 automatically flows into the water storage container 19. Therefore, the controller 4 can detect both the attachment of the tank member 20 to the water storage container 19 and the supply of water from the tank member 20 into the water storage container 19 by the water level detector 25. Alternatively, the air cleaning device may have an optical, mechanical, electrical, magnetic, or other physical sensor other than the water level detector 25 to detect the state in which the tank member 20 is attached to the water storage container 19. The control unit 4 can receive a signal from such a sensor and detect that the tank member 20 is attached to the water storage tank 19. Alternatively, the air cleaning device may have an operation button for receiving a notification from the user that the operation of attaching the tank member 20 has been completed. For example, if the mounting operation of the can member 20 is completed, the user presses the operation button. The control unit 4 receives a signal from the operation button, and can detect that the tank member 20 is attached to the water storage tank 19.

The control unit 4 is electrically connected to the power plug 28. The control unit 4 detects the voltage input through the power plug 28, and thereby can detect connection or disconnection of the power plug 28 to or from the external power supply.

The control unit 4 may have a timer therein. The control unit 4 measures the operation time by a timer.

In other words, the operation time is the time during which the air cleaning device operates from the time when the user starts the operation of the air cleaning device by putting water into the tank member 20 to the time when the user moves the air cleaning device and connects the power plug 28 to the external power supply again to start the operation of the air cleaning device. The control unit 4 compares the operation time with a predetermined time.

The predetermined time is equal to or longer than time 1 and equal to or shorter than time 2, where time 1 is the time taken until the full tank of water placed in tank member 20 disappears when electrolysis unit 22 and blower 2 are operated in an operation mode (for example, a weak mode) in which the full tank of water placed in tank member 20 disappears most slowly, and time 2 is the time added by 48 hours to time 1.

The water put into the tank part 20 is consumed at a consumption rate corresponding to the operation mode. The consumption rate is the amount of consumption per unit time. The operation mode in which the full tank of water put in the tank member 20 is lost at the slowest means an operation mode having the smallest consumption rate.

The predetermined time may be a time obtained by adding a time in the range of 5 hours to 8 hours to a time taken until the full tank of water put into the tank member 20 disappears when the electrolysis unit 22 and the blower 2 are operated in an operation mode (for example, a weak mode) in which the full tank of water put into the tank member 20 disappears most slowly. An example of the predetermined time is 24 hours. The control unit 4 determines whether the operation time is the same as or longer or shorter than the predetermined time. The control unit 4 prompts the user to drain the water in the water storage tank 19 by the maintenance lamp 6b when the operation time is longer than the predetermined time, and starts the operation of the electrolysis unit 22 and the fan 2 when the operation time is the same as or shorter than the predetermined time. This can reduce unnecessary drainage work.
