[0009] (Embodiment 1) Figure 1 is a perspective view of the air purification device according to Embodiment 1 of the present invention, showing the air purification device from the front. Figure 2 is a cross-sectional view of the air purification device from the right side.

[0010] In the following, as shown in FIG. 1, the vertical direction in the state where the air purifier is installed (hereinafter also referred to as the "installed state") may be described as the up and down direction, and the horizontal direction as the left and right direction. Further, in the following, in the installed state, the surface of the air purifier on which the panel is provided is defined as the "front surface", the surface facing the front surface of the air purifier is defined as the "back surface", the right side surface when viewed from the front side of the air purifier is defined as the "right side surface", and the left side surface is defined as the "left side surface".

[0011] Hereinafter, the detailed configuration of the air purifier will be described. As shown in FIGS. 1 and 2, the air purifier 1 of the present embodiment includes a substantially box-shaped main body case 2, a blower 3, an air purification unit 4, a control unit 5, and an operation unit 6.

[0012] The main body case 2 has a substantially box shape and has an intake port 7 and an outlet port 8.

[0013] The intake port 7 is arranged on both side surfaces (left and right side surfaces) of the main body case 2.

[0014] The outlet port 8 is of an openable and closable type and is provided on the top surface of the main body case 2. In FIGS.

[0015] 1 and 2, the outlet port 8 is in an open state. An operation unit 6 is provided on the front side of the top surface of the main body case 2.

[0015] An openable and closable panel 9 is provided on the front surface of the main body case 2.

[0016] When the panel 9 is opened, a part of the air purification unit 4, namely, a water storage container 19, a tank member 20, and a gas-liquid contact part 21, which will be described later, can be taken out of the main body case 2.

[0017] An air passage 12 communicating the intake port 7 and the outlet port 8 is provided inside the main body case 2. In the air passage 12, in order from the intake port 7, a part of the air purification unit 4, namely, a water storage container 19, a gas-liquid contact part 21, a blower 3, and an outlet port 8 are provided.

[0018] The blower 3 is provided at the central part of the main body case 2, and includes a motor part (not shown), a fan part 14 that rotates by the motor part, and a scroll-shaped casing part 15 that surrounds them.

[0019] The motor part is fixed to the casing part 15.

[0020] The fan part 14 is a sirocco fan and is fixed to a rotating shaft (not shown) that extends horizontally from the motor part (not shown).

[0021] The casing part 15 is provided with a discharge port 17 and a suction port 18. The discharge port 17 is provided on the upper surface side of the main body case 2 of the casing part 15. Further, the suction port 18 is provided on the back side of the main body case 2 of the casing part 15.

[0022] The air purification part 4 includes a water storage container 19, a tank member 20, a gas-liquid contact part 21, and an electrolysis unit 22.

[0023] The water storage container 19 has a box shape with an opening provided on the top surface and has a structure capable of storing water. The water storage container 19 is arranged at the lower part of the main body case 2 and is slidable horizontally and detachable. The water storage container 19 stores the water supplied from the tank member 20.

[0024] Figure 3 is a perspective view of the tank member of Embodiment 1 of the present invention. Figure 4 is a perspective view of the gas-liquid contact part 21 of Embodiment 1 of the present invention, and shows a state where a filter 26 and a filter frame 27 are attached to the water storage container 19.

[0025] As shown in Figures 3 and 4, the tank member 20 is installed in the lower part of the main body case 2 and is detachable from the water storage container 19. The tank member 20 is attached to a tank holder 23 provided on the bottom surface of the water storage container 19. The tank member 20 comprises a water storage tank 24 and a lid 25 provided on the opening (not shown) of the tank 24. An opening / closing part (not shown) is provided in the center of the lid 25, and when this opening / closing part is opened, water from the tank 24 is supplied to the water storage container 19. Specifically, when the opening of the tank 24 is facing downwards and the tank member 20 is attached to the tank holder 23 of the water storage container 19, the opening / closing part is opened by the tank holder 23. In other words, when water is put into the tank member 20 and attached to the tank holder 23, the opening / closing part opens and water is supplied from the tank member 20 to the water storage container 19, and water accumulates in the water storage container 19. When the water level in the water storage container 19 rises and reaches the lid 25, the opening of the tank component 20 is sealed with water, and the water supply stops. Water remains inside the tank component 20, and whenever the water level in the water storage container 19 drops, water from inside the tank 24 is supplied to the water storage container 19. In other words, the water level in the water storage container 19 is kept constant.

[0026] The gas-liquid contact portion 21 is a component that brings the water stored in the water storage container 19 into contact with the indoor air drawn into the main body case 2 by the blower 3. The gas-liquid contact portion 21 includes a filter 26, a filter frame 27, and a drive unit (not shown).

[0027] The filter 26 is cylindrical in shape and has holes in its circumference that allow air to flow through. The filter 26 is mounted on the filter frame 27 such that one end of the filter 26 is immersed in the water in the water storage container 19.

[0028] The filter frame 27 is rotatably supported by a bearing portion 28 provided in the water storage container 19. The filter 26 and the filter frame 27 are structured to rotate together by a drive unit.

[0029] As shown in Figure 2, the electrolytic unit 22 is mounted in the main body case 2 so as to be movable in the vertical direction. Figure 2 shows the electrolytic unit 22 in a downward position. The electrolytic unit 22 has a first electrode (not shown) and a second electrode (not shown). When the water storage container 19 is attached to the bottom of the main body case 2 and the electrolytic unit 22 is moved downward, the first electrode and the second electrode are immersed in the water storage container 19. When a voltage is applied to the first electrode and the second electrode while they are immersed in the water storage container, the water in the water storage container 19 containing an electrolytic accelerating solvent (not shown) added by the user is electrochemically treated. An example of an electrolytic accelerating solvent is sodium chloride, and hypochlorous acid is generated from the sodium chloride aqueous solution by the electrolytic unit.

[0030] The control unit 5 controls the electrolytic unit 22, the gas-liquid contact part 21 (drive unit), and the blower 3 (motor unit). Specifically, the control unit 5 controls the voltage applied to the first and second electrodes of the electrolytic unit 22, the operation of the drive unit which is the gas-liquid contact part 21, and the rotation speed of the fan unit 14 which is the blower 3, in response to the operation of the operation unit 6. When the fan unit 14 rotates due to the motor unit of the blower 3, the outside air that enters the main body case 2 from the intake port 7 is blown out of the main body case 2 in order through the air purification unit 4 (water storage container 19, filter 26), the blower 3, and the outlet port 8.

[0031] Figure 5 is a perspective view of the air purifier according to Embodiment 1 of the present invention with the storage member attached. Figure 6 is a perspective view of the storage member of the air purifier according to Embodiment 1 of the present invention. Figure 7 is a cross-sectional view of the air purifier according to Embodiment 1 of the present invention with the storage member attached.

[0032] As shown in Figures 5, 6, and 7, a feature of this embodiment is the configuration of a hollow storage member 30 capable of storing small items. The storage member 30 is detachably attached to the air outlet 8, and when the storage member 30 is attached to the air outlet 8, the air blown out from the air outlet 8 enters the storage member 30 and is blown out from the discharge port 31 of the storage member 30. The discharge port 31 has a guide member 32 that guides the air blown out from the discharge port 31 to the intake port 7 of the main body case 2.

[0033] As described above, the storage component 30 can be attached to and detached from the air outlet 8. When the storage component 30 is attached to the air outlet 8, spot disinfection can be performed by blowing hypochlorous acid intensively onto small items placed in the storage component 30 to disinfect them. When the storage component 30 is removed from the air outlet 8, space disinfection can be performed to disinfect the entire room in which the air purifier is placed.

[0034] Furthermore, during spot disinfection, the device is equipped with a guide member 32 that directs the air blown out from the outlet 31 of the storage component 30 to the outlet 8 of the main case 2. This ensures that hypochlorous acid is consumed within the storage component 30, and prevents mainly water-containing air from being blown into the room. In other words, even during the rainy season or when indoor humidity is high, spot disinfection of small items placed in the storage component 30 can be performed without causing excessive humidity in the room.

[0035] Specifically, the storage member 30 includes a first duct section 33, a discharge attachment / detachment section 34, a bag section 35, and a guide member 32.

[0036] The first duct section 33 has a cylindrical shape with an internal air passage. One open end of the first duct section 33 has a dispensing attachment section 34, and the other open end of the first duct section 33 has a bag section 35 capable of storing small items. The first duct section 33 connects the dispensing attachment section 34 and the bag section 35, and the air blown out into the dispensing attachment section 34 flows into the bag section 35 via the first duct section 33.

[0037] The detachable outlet section 34 is detachable from the horizontally elongated rectangular tubular outlet 8, whose central axis extends vertically. The detachable outlet section 34 is a horizontally elongated box shape with an open bottom and a first hole 37 on its top surface. The first duct section 33 extends from the first hole 37. The detachable outlet section 34 is slightly smaller than the horizontally elongated rectangular tubular outlet 8, and when the detachable outlet section 34 is inserted into the outlet 8 through the upper opening of the horizontally elongated rectangular tubular outlet 8, it fits inside the outlet 8.

[0038] The bag portion 35 is roughly box-shaped and has an opening 38 on its top surface that can be opened and closed. Small items can be put in and taken out through the opening 38. The bag portion 35 has a hole 39 on one side, from which the first duct portion 33 extends. The bag portion 35 has a discharge port 31 on the other side from which air blown into the bag portion 35 is blown out. A guide member 32 is provided at the discharge port 31. One open end of the first duct portion 33 is detachably attached to the first hole 37 of the blowing attachment portion 34, and the other open end of the first duct portion 33 is detachably attached to the hole 39 of the bag portion 35.

[0039] The guide member 32 has a second duct portion 41 and an intake attachment / detachment portion 42.

[0040] The second duct section 41 extends from the discharge port 31 and has a cylindrical shape with an air passage inside. An intake / detachment section 42 is provided at the tip of the second duct section 41.

[0041] The intake attachment / detachment section 42 is detachably attached to the intake port 7 and is configured to cover a part of the intake port 7. The intake attachment / detachment section 42 is a vertically elongated box shape with one side open, and has a hole 40 on that side. The second duct section 41 extends from the hole 40. Specifically, the intake port 7 of the main body case 2 has a first intake port 7a and a second intake port 7b. The first intake port 7a is provided on one side (left side) of the main body case 2, and the second intake port 7b is provided on the other side (right side) of the main body case 2. The intake attachment / detachment section 42 is detachably attached to the second intake port 7b, which is a vertically elongated rectangular tube shape with its central axis extending in the left-right direction, and is configured to cover the second intake port 7b. Furthermore, one open end of the second duct section 41 is detachably attached to the discharge port 31 of the bag section 35, and the other open end of the second duct section 41 is detachably attached to the hole 40 of the intake attachment / detachment section 42.

[0042] Figure 8 is a perspective view of the air purification device according to Embodiment 1 of the present invention with the storage member attached, showing the opening adjustment section 44 in the open state. Figure 9 is a perspective view of the air purification device according to Embodiment 1 of the present invention with the storage member attached, showing the opening adjustment section 44 in the closed state.

[0043] Furthermore, as shown in Figures 8 and 9, the detachable air outlet section 34 is configured to cover a portion of the air outlet 8. Specifically, the detachable air outlet section 34 has a second hole 43. As a result, some of the air containing hypochlorous acid that flows from the air outlet 8 into the detachable air outlet section 34 flows into the bag section 35 via the first hole 37 and the first duct section 33, disinfects the small items inside the bag section 35, and then flows into the discharge port 31. Similarly, some of the air containing hypochlorous acid that flows from the air outlet 8 into the detachable air outlet section 34 flows out into the room via the second hole 43. In this way, the small items inside the storage member 30 can be disinfected at the same time as the indoor air is purified. Moreover, the hypochlorous acid is consumed within the storage member 30, which suppresses the release of air mainly containing water into the room.

[0044] Furthermore, the detachable outlet section 34 has an opening adjustment section 44 that adjusts the opening area of ​​the outlet 8 that is not covered by the detachable outlet section 34. In other words, the opening adjustment section 44 adjusts the opening area of ​​the second hole 43 of the detachable outlet section 34. Specifically, the opening adjustment section 44 has a sliding plate 45 and a knob 46. The sliding plate 45 is roughly plate-shaped and is provided on the detachable outlet section 34 so as to be movable in the left-right direction within the second hole 43. The knob 46 is a projection that protrudes upward from the upper surface of the sliding plate. By grasping the knob and moving it in the left-right direction, the opening area of ​​the second hole 43 can be adjusted.

[0045] In this way, by adjusting the opening area of ​​the second hole 43 of the air outlet attachment / detachment section 34, the amount of air flowing into the storage member 30 can be adjusted, and the sterilization time can be adjusted. If you want to sterilize small items inside the bag section 35 quickly, you can shorten the sterilization time by narrowing the opening area of ​​the second hole 43 and increasing the amount of air flowing into the bag section 35. [Industrial applicability]
