  Conventionally, this type of humidified air purifier has the following configuration.

  That is, a main body case having an intake port and an exhaust port, an air purification filter provided in the air passage in the main body case, a blower provided on the downstream side of the air passage of the air purification filter, the air purification filter, and the A humidifying container provided in the air passage between the blower, a humidifying body having its lower end immersed in humidified water in the humidifying container, and an exhaust path guide plate provided on the upstream side of the humidifying container Thus, during the humidified air cleaning operation, the air sucked from the intake port by the blower is blown to the exhaust port via the air cleaning filter and the humidifier, and is sucked from the intake port during the air cleaning operation. The air passes through the air purification filter by changing the blowing direction from the air purification filter to the direction of the exhaust port by the guide plate of the exhaust path. The blowing of the wet product had been configured to suppress (e.g., Patent Document 1 exists as prior art documents similar thereto).

JP 2005-61655 A

  The problem in the above conventional example is that a slightly dry odor is generated in the early stage of use of the humidifier.

  That is, when used as an air purifier, the exhaust path is closed with a guide plate so that the air from the blower does not reach the humidifier, and at this time, the air is sucked from the air intake of the main body case. The room air passes through the filter and is purified, and then discharged from the exhaust port into the room through the blower.

  However, since the lower end of the humidifying body is immersed in the humidifying water at this time, the upper end portion of the humidifying body is gradually dried due to evaporation of moisture.

  Therefore, in this state, when the guide plate is opened and the humidifier is used, the upper end portion is blown to the humidified body, and at this time, the freshly dried odor is discharged into the room from the exhaust port.

  This is well known as a raw dry odor generated in the early stage of humidification, but countermeasures are required.

  Therefore, the object of the present invention is to suppress the generation of this odor.

  In order to achieve this object, the present invention provides a main body case having an intake port and an exhaust port, an air purifying filter provided in an air passage in the main body case, and the air passage downstream side of the air purifying filter. A humidifier provided in the air path between the air purifying filter and the blower, a humidifying body having its lower end immersed in humidified water in the humidifying container, and the wind A wind direction changing plate provided on the road, a rotating means for rotating the humidifier and the wind direction changing plate, and a control means for switching between the humidified air cleaning operation and the air cleaning operation. During operation, air sucked from the intake port by the blower is blown to the exhaust port through the air purification filter and the humidifier, and during air cleaning operation, air sucked from the intake port is blown. Through the air purifying filter, by controlling the air blowing from the air purifying filter to the direction of the blower by the air direction changing plate, thereby suppressing the air blowing to the humidifying body and at the time of humidified air cleaning operation In the air cleaning operation, the moisture content of the upper end portion of the humidifying body is larger, thereby achieving the initial purpose.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, an air purification filter provided in an air passage in the main body case, a blower provided on the downstream side of the air passage of the air purification filter, A humidifying container provided in the air path between the air purification filter and the blower, a humidifying body having its lower end immersed in humidified water in the humidifying container, and a wind direction change provided in the air path A plate, a rotating means for rotating the humidifying body and the wind direction changing plate, and a control means for switching to a humidified air cleaning operation and an air cleaning operation. By this control means, during the humidified air cleaning operation, Air sucked from the intake port is blown to the exhaust port through the air purification filter and the humidifier, and air sucked from the intake port during the air cleaning operation is The air direction is changed by the air direction change plate to the direction of the blower and the air to the humidifier is suppressed by the air direction changing plate, and the air cleaning operation is performed from the time of the humidified air cleaning operation. Occurrence of odor can be suppressed by the fact that the moisture content of the upper end portion of the humidifier is larger at the time.

  That is, in the present invention, the air blowing from the air purifying filter is changed to the direction of the blower by the air direction changing plate to suppress the blowing to the humidifier, and at the time of the air cleaning operation from the humidified air cleaning operation. By increasing the water content at the upper end of the humidifier, the generation of odor can be suppressed.

  That is, at the time of the air cleaning operation without humidification by the control means, the amount of water sucked up by the humidifying body is increased by switching from the humidified air cleaning operation to the air cleaning operation by the rotating means that rotates the humidifying body and the wind direction changing plate, and as a result As described above, the upper end portion of the humidifying body is always in a wet state and does not become a dry state.

  As a result, even when switching from the air cleaning operation to the humidified air cleaning operation, generation of a freshly dried odor at the initial stage of humidification can be suppressed.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 1, a humidified air purifier is installed on the floor of a room and can selectively perform an air cleaning operation and a humidified air cleaning operation as will be described later.

  As shown in FIGS. 1 and 2, the humidified air cleaner has a box-shaped main body case 3 having a front side air inlet 1 and an upper side air outlet 2. An air purification filter 4 is provided in the air passage near the air inlet 1 in the main body case 3, and a blower 5 is provided on the downstream side of the air purification filter 4. A humidifying container 6 is provided in the air path between the air cleaning filter 4 and the blower 5. The humidifying container 6 is provided with a mesh-like humidifier 8 in which a certain amount of humidified water is supplied from a water supply tank 7 and the lower end of the humidifying container 6 is immersed in the humidified water. Further, the air passage in the humidifying container 6 has a wind direction changing plate 9. The blower 5 is located above the humidifier 8. The air sucked from the air inlet 1 of the main body case 3 by the blower 5 first passes through the air cleaning filter 4, then flows downward in the air passage, passes through the humidifying container 6, and further upwards the air passage. The air is blown into the room from the exhaust port 2 via the blower 5.

  The feature in the present embodiment is that a rotating means 10 for rotating the humidifying body 8 and the wind direction changing plate 9 and a control means 13 for switching between a humidified air cleaning operation and an air cleaning operation are provided.

  In this way, during the humidified air cleaning operation, the air sucked from the intake port 1 by the blower 5 is blown to the exhaust port 2 via the air purification filter 4 and the humidifier 8 by the control means 13. During the air cleaning operation, the air sucked from the air inlet 1 changes the blowing direction from the air cleaning filter 4 to the direction of the blower 5 by the air direction changing plate 9 through the air cleaning filter 4. While suppressing the ventilation to the humidifying body 8, the control means increases the water content of the upper end portion of the humidifying body 8 during the air cleaning operation than during the humidifying air cleaning operation.

  That is, in the present invention, the air blowing from the air purification filter 4 is changed to the direction of the blower 5 by the wind direction changing plate 9 to suppress the blowing to the humidifying body 8 and the air from the humidified air cleaning operation. Odor generation can be suppressed by increasing the water content of the upper end of the humidifier 8 during the clean operation.

  That is, the amount of water that the humidifying body 8 sucks up by switching from the humidified air cleaning operation to the air cleaning operation by the rotating means 10 that rotates the humidifying body 8 and the wind direction changing plate 9 during the air cleaning operation without humidification by the control means 13. As a result, the upper end portion of the humidifying body 8 is always in a wet state and does not become a dry state.

  As a result, even when switching from the air cleaning operation to the humidified air cleaning operation, generation of a freshly dried odor at the initial stage of humidification can be suppressed.

  Also, as shown in FIGS. 3 and 4, the upper end of the humidifying body 8 is positioned lower during the air cleaning operation than during the humid air cleaning operation.

  Specifically, the humidifying container 6 is provided with two support portions 14 that are substantially bowl-shaped with an open top surface and extend upward from the bottom surface. A filter frame 11 is rotatably provided on the support portion 14. The filter frame 11 has a substantially rectangular frame shape with a horizontally long square shape, and includes two shaft portions 15 having a substantially cylindrical shape extending outwardly on the side surface on the short side, and the shaft portion 15 is attached to the support portion 14. It is pivotally supported. From one side of the long side of the filter frame 11, a horizontally long flat plate-shaped wind direction changing plate 9 extends.

  As shown in FIG. 4 (a), during the humidified air cleaning operation, the filter frame 11 is positioned substantially perpendicular to the humidifying container 6. At this time, the wind direction changing plate 9 is attached to the lower part of the filter frame 11, The filter frame 11 extends at a predetermined angle upward from the wind path. Then, as shown in FIG. 4B, during the air cleaning operation, the filter frame 11 is rotated by being rotated by the rotating means 10, and the filter frame 11 is inclined to the humidifying container 6, and at this time The wind direction changing plate 9 is attached to the upper part of the filter frame 11, and the wind direction changing plate 9 extends from the upper part to the lower side of the wind path with a predetermined angle with the filter frame 11.

  That is, in the humidified air cleaning operation, the humidifying body 8 is positioned substantially perpendicular to the air path, and the wind passing through the air path passes through the entire humidifying body 8. However, in the air cleaning operation, the humidifying body 8 The humidifying body 8 and the wind direction changing plate 9 are rotated by the means for rotating the wind direction changing plate 9 so that the wind hits the wind direction changing plate 9 and no wind is applied to the humidifying body 8. Further, since the humidifying body 8 rotates, the position of the upper end of the humidifying body in the air cleaning operation becomes lower than that in the humidifying operation.

  The humidifier 8 of the main body of the humidified air cleaner used in the present invention sucks up water by utilizing the capillary phenomenon. Water sucked up by capillarity is attached to the connecting thread and retains water, but as it goes to the top, the sucking efficiency becomes worse and the amount of water retained also decreases. Thereby, the humidifying body 8 having the sucking function because the upper end portion of the humidifying body is low during the air cleaning operation has a larger amount of water retention than when the upper portion is at a high position.

  As a result, the amount of water retained at the upper end of the humidifying body 8 during the air cleaning operation is larger than that during the humidifying air cleaning operation, and the wind to the humidifying body 8 by the wind direction changing plate 9 is obstructed and the upper end is less likely to be dry. , Leading to a reduction in the odor of raw dryness.

  Further, during the humidified air cleaning operation, the wind direction changing plate 9 is positioned on the downstream side of the air path of the humidifying body 8 by the rotating means 10 and changes the blowing direction of the air blown from the humidifying body 8 toward the blower 5. It is a thing.

  Specifically, the humidifier 8 is housed in a filter frame 11, and a wind direction changing plate 9 is provided on one side of the filter frame 11. One end of the filter frame 11 is provided with a gear 12 that is in contact with the rotation means 10, so that the rotation of the rotation means 10 during the air cleaning operation causes the filter frame 11 to rotate and the wind direction changing plate 9 to be on the upper side. Position to be. Here, the filter frame 11 is positioned substantially perpendicular to the humidifying container 6, and at this time, the wind direction changing plate 9 is attached to the lower part of the filter frame 11 and extends from the lower part to the upper side of the wind path.

  As a result, the air that has passed through the humidifying body 8 and has been humidified changes in the wind direction upward by the wind direction changing plate 9, and easily flows to the blower 5 positioned above the humidifying body 8. That is, when the humidifying body 8 is positioned in a substantially vertical direction, the wind direction changing plate 9 attached to the humidifying body 8 functions as a rectifying plate, thereby reducing the pressure loss in the airframe, leading to a reduction in power consumption and noise. .

  In addition, during the humidified air cleaning operation, the humidifier 8 is configured to be positioned in a substantially vertical direction. Specifically, during the humidified air cleaning operation, the filter frame 11 and the humidifying body 8 are positioned substantially perpendicular to the humidifying container 6, and at this time, the wind direction changing plate 9 is attached to the lower part of the filter frame 11, The road extends upward on the windward side. The humidifying body 8 having a mesh shape is formed of two first layers and a second layer between the first layers, and the second layer connects the two first layers. A plurality of connecting yarns are provided, and a plurality of communication holes surrounded by these connecting yarns are provided.

  That is, since the humidifying body 8 is positioned substantially perpendicular to the humidifying container 6, the communication hole of the humidifying body 8 opens in the horizontal direction, so that air easily flows from the front side to the back side in the main body case.

  In the air cleaning operation, the lower end portion of the wind direction changing plate 9 is configured to be positioned lower than the lower end of the intake port.

  That is, during the air cleaning operation, the amount of air flowing through the humidifier 8 is reduced more than when the lower end of the wind direction changing plate 9, that is, the tip of the wind direction changing plate 9 is lower than the lower end of the intake port. As a result, the amount of air flowing through the humidifying body 8 is reduced, so that drying of the humidifying body 8 is suppressed, leading to a reduction in the odor of fresh drying.

  Further, a sterilizing unit 16 is provided in the humidified water in the humidifying container 6. Accordingly, the use of the sterilization unit 16 in the humidified water in the humidification container 6 prevents the propagation of various bacteria. Although the upper part of the humidifying body 8 is wetter during the air cleaning operation than that during the humidifying air cleaning operation, there may still be some raw dryness. In this case, there is propagation of miscellaneous bacteria as one of the causes of the raw dry odor, but the use of the sterilization unit 16 can prevent the propagation and, as a result, the odor level is also reduced.

  As an example of the sterilization unit 16, a first electrode and a second electrode having different oxidation-reduction potentials installed with a gap and a short-circuit portion that short-circuits the electrodes are provided, and the oxidation-reduction of the first electrode The potential is higher than the oxidation-reduction potential of the second electrode, and the first electrode and the second electrode are arranged at a position in contact with water. Thereby, propagation of miscellaneous bacteria can be suppressed by the influence of metal ions eluted from the surface of the second electrode.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, an air purification filter provided in an air passage in the main body case, a blower provided on the downstream side of the air passage of the air purification filter, A humidifying container provided in the air path between the air purification filter and the blower, a humidifying body having its lower end immersed in humidified water in the humidifying container, and a wind direction change provided in the air path A plate, a rotating means for rotating the humidifying body and the wind direction changing plate, and a control means for switching to a humidified air cleaning operation and an air cleaning operation. By this control means, during the humidified air cleaning operation, Air sucked from the intake port is blown to the exhaust port through the air purification filter and the humidifier, and air sucked from the intake port during the air cleaning operation is The air direction is changed by the air direction change plate to the direction of the blower and the air to the humidifier is suppressed by the air direction changing plate, and the air cleaning operation is performed from the time of the humidified air cleaning operation. Occurrence of odor can be suppressed by the fact that the moisture content of the upper end portion of the humidifier is larger at the time.

  That is, in the present invention, the air blowing from the air purifying filter is changed to the direction of the blower by the air direction changing plate to suppress the blowing to the humidifier, and at the time of the air cleaning operation from the humidified air cleaning operation. By increasing the water content at the upper end of the humidifier, the generation of odor can be suppressed.

  That is, at the time of the air cleaning operation without humidification by the control means, the amount of water sucked up by the humidifying body is increased by switching from the humidified air cleaning operation to the air cleaning operation by the rotating means that rotates the humidifying body and the wind direction changing plate, and as a result As described above, the upper end portion of the humidifying body is always in a wet state and does not become a dry state.

  As a result, even when switching from the air cleaning operation to the humidified air cleaning operation, generation of a freshly dried odor at the initial stage of humidification can be suppressed.

  Therefore, it becomes extremely useful as a humidified air cleaner.
