  The humidifying device according to claim 1 of the present invention is a main body case having an air inlet for sucking air into the interior, an exhaust port for discharging the sucked air to the outside, a humidifier provided in the main body case, A water supply means for supplying water to the humidifier, a blower fan that discharges the sucked air from the exhaust port to the outside of the main body case after contacting the humidifier, and from the humidifier to the exhaust port The blast passage is provided with a sterilization means for emitting a sterilizing substance, and further includes a control unit that drives the blast fan and the sterilization means, and the control unit has a predetermined humidification operation time when the humidification operation is stopped. The operation time determination means for determining that the time has been exceeded, and the sterilization operation means for passing the sterilizing substance through the humidifier when the operation time exceeds a predetermined time.

  Thereby, when the humidifying operation is stopped, if the operation time determining means determines that the time of the humidifying operation exceeds a predetermined time, the disinfecting operation means passes the disinfecting substance to the humidifying body. Therefore, the propagation of bacteria can be suppressed, and the odor at the start of the next operation and during operation can be suppressed.

  The humidifying device according to claim 2 includes a mixed flow fan that can rotate forward and backward as a blower fan, and the sterilization operation means drives the sterilization means when the operation time exceeds a predetermined time. The air blowing fan is rotated in the reverse direction so that air flows from the exhaust port to the humidifier and the intake port.

  Thereby, the sterilization operation means drives the sterilization means when the operation time exceeds a predetermined time, and reversely rotates the blower fan to flow air from the exhaust port to the humidifier and the intake port. As a result, the sterilizing substance passes through the humidified body, so that the growth of the bacteria can be suppressed, and the odor at the start of the next operation and during the operation can be suppressed.

  Further, the humidifying device according to claim 3 is configured such that a frame body provided with a filter at an intake port and a front side slit and a back side slit in a horizontal direction are alternately formed from the upper part of the frame body to the front side and the back side. Provided with a shielding plate that connects the front slit and the end of the back slit, the interval between the slits on the same surface side is larger than the height of the slit, and the filter is arranged between adjacent front slits .

  As a result, when air flows from the humidifier toward the intake port, the air is collected to the slit on the front side by the action of the shielding plate, and the air can flow outside the main body case. In other words, when air is blown from the exhaust port to the humidifier and the intake port, the air flows from the intake port to the outside of the main body case without blowing off the dust collected by the filter. Therefore, the sterilizing substance passes through the humidified body to suppress the growth of the bacteria, and the odor at the start of the next operation and during the operation can be suppressed.

  According to a fourth aspect of the present invention, there is provided a humidifier according to the present invention, wherein the intake port is provided with a filter on the front side, the upper part is pivotally supported by a rotating shaft in the horizontal direction, and the frame is rotated outward from the main body case. The back side of the frame body is extended from the adjacent back side slits toward the front side of the frame body so as to form a horizontal back side slit at a predetermined interval from the upper part, and the front end portion is closed. It has the structure provided with the shielding board.

  Thereby, when air flows from the humidifier toward the intake port, the shielding plate receives air from the back side of the air frame body to the front side, thereby exerting a force for pushing out the filter frame. That is, the frame body rotates around the rotation axis, and a gap is formed between the frame body and the main body case, so that it is easy to discharge the air inside the main body case. The substance can pass through the humidified body to suppress the growth of bacteria, and the odor at the start of the next operation and during operation can be suppressed.

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

(Embodiment 1)
In FIG. 1, the humidifier 1 has a box-shaped main body case 2, the left side and the back side are the intake port 3 shown in FIG. 2, the upper surface is the exhaust port 4, the operation unit 5, and the display unit 6. A mounting port 8 for a water tank 7 (an example of water supply means) is provided.

  Further, a humidifying body 9 is provided in the main body case 2 as shown in FIG.

  The humidifier 9 has a configuration in which the lower part is disposed in the water dish 10 and the upper part is raised upward.

  That is, the water in the water tank 7 is supplied to the water tray 10 at a constant water level, and the humidifier 9 in a porous state sucks the water upward.

  In addition, a water level sensor 11 for detecting drought is provided in the water dish 10.

  Further, in the main body case 2, a DC-driven blower fan 12 is provided between the humidifier 9 and the exhaust port 4.

  The blower fan 12 is, for example, a mixed flow fan having a wind tunnel 13 on the outer periphery.

  In the main body case 2, in a normal humidifying operation, as shown in FIG. 2, the air sucked into the main body case 2 from the air inlet 3 is passed through the porous humidifier 9, and then passed through the blower fan 12. The ventilation path 14 is formed so that it may ventilate to the exhaust port 4 and humidify by this.

  Further, in the air passage 14, a passage from the humidifier 9 to the exhaust port 4 is provided with a sterilization means 15 that causes the air passing through the humidifier 9 to include a sterilizing substance and discharge the air from the exhaust port 4.

  The main body case 2 includes a control unit 16 that drives the blower fan 12 and the sterilization means 15. As shown in FIG. 3, the operation unit 5 and the water level sensor 11 are connected to the control unit 16 as inputs, and the display unit 6, the sterilization unit 15, and the blower fan 12 are connected as outputs.

  As shown in the flowchart of FIG. 4, the operation of the control unit 16 includes a first operation mode 17 in which humidification is performed as in the prior art, and a second operation in which the humidifier 9 is sterilized every predetermined time. An operation mode 18 (clean mode) is provided.

  The second operation mode 18 is a mode in which the sterilization means 15 is made to act on the air that has passed through the humidifying body 9 so that the sterilizing substance is included and the humidification operation is performed.

  Further, in the second operation mode 18, when the humidifying operation time is shifted to the stop, when the humidifying operation time exceeds a predetermined time, the disinfecting means 15 is operated to allow the disinfecting substance to pass through the humidifying body 9. Is.

  In particular, in order to realize the second operation mode 18, in the present embodiment, the blower fan 12 can be rotated forward and backward, and the controller that drives the blower fan 12 and the sterilization means 15 that emits a sterilizing substance. 16 is provided. Further, as shown in FIG. 4, the control unit 16 includes an operation time determination unit that determines that the accumulated humidification operation time has exceeded a predetermined time when the humidification device 1 shifts to the humidification operation stop. 20 and sterilization operation means 21 for allowing the sterilizing substance to pass through the humidifying body 9 when it is determined that the operation time has exceeded a predetermined time.

  In the above configuration, when the humidifying operation is started by the operation unit 5, the control unit 16 confirms the operation mode as shown in FIG.

  First, when the clean mode button (not shown) is not pressed, that is, in the first operation mode 17, the fan 12 is rotated forward and the operation is continued until the next stop operation is performed. Will be.

  That is, when the blower fan 12 performs the forward rotation operation, the air sucked into the main body case 2 from the intake port 3 is passed through the humidified body 9 in the porous state. At this time, a part of the water sucked up by the humidifying body 9 is evaporated, and then the air is blown to the exhaust port 4 through the blower fan 12, whereby humidification is performed.

  Further, in the passage from the internal humidifier 9 to the exhaust port 4 in the blower passage 14, the sterilization means 15 includes a sterilizing substance in the air that has passed through the humidifier 9, so that the humidification discharged from the exhaust port 4 A room-containing air environment can be improved by adding a sterilizing substance to the air.

  As shown in FIG. 4, in the first operation mode 17, while the humidifying operation time is counted by the integration timer 19, it is confirmed by the water level sensor 11 that the water in the water dish 10 is not drought. While humidifying.

  That is, when the operation is performed while the humidifying operation time is measured, and when the water becomes dry, the display unit 6 displays that the water is out, and the operation is stopped.

  That is, it is possible to prevent the operation from being continued in a drought state where the humidification performance cannot be sufficiently obtained.

  Next, when the clean mode button is pressed, that is, in the second operation mode 18, the blower fan 12 is rotated forward, and then operated until the luck time by the stop operation or the operation timer expires. Will be continued.

  That is, similarly to the first operation mode 17, when the blower fan 12 performs forward rotation, the air sucked into the main body case 2 from the intake port 3 is passed through the porous humidifier 9. At this time, a part of the water sucked up by the humidifying body 9 is evaporated, and then the air is blown to the exhaust port 4 through the blower fan 12, whereby humidification is performed.

  Further, in the passage from the internal humidifier 9 to the exhaust port 4 in the blower passage 14, the sterilization means 15 includes a sterilizing substance in the air that has passed through the humidifier 9, so that the humidification discharged from the exhaust port 4 It is also possible to improve the indoor air environment by including a sterilizing substance in the air.

  As shown in FIG. 4, in the second operation mode 18, the operation time is counted by the integration timer 19, and the water level sensor 11 is used to confirm that the water in the water dish 10 is not drought. Humidification is performed.

  For example, when the operation time by the operation timer expires, the operation time determination means 20 indicates that the accumulated humidification operation time (t) exceeds a predetermined time (for example, 8 hours) before shifting to operation stop. Will be determined. If the predetermined time is not exceeded, the operation is stopped as it is.

  When the predetermined time is exceeded, the sterilization operation means 21 controls the blower fan 12 so that the sterilizing substance passes through the humidifying body 9.

  That is, the sterilization operation means 21 drives the blower fan 12 in the reverse rotation while driving the sterilization means 15. As shown in FIG. 5, when the blower fan 12 rotates in the reverse direction, the mixed flow fan causes air to flow in the reverse direction, and air is sucked into the main body case 2 from the exhaust port 4, and the blower passage 14 is directed in the reverse direction. The air passing through the blower fan 12 contains a sterilizing substance by the sterilization means 15, passes through the humidifier 9, and is discharged from the intake port 3.

  At this time, since the sterilizing substance is allowed to pass through the humidifying body 9, the inside and back of the humidifying body 9 and both sides of the front surface can be brought into contact with each other, so that a high sterilizing effect can be obtained.

  Here, it is preferable that the air volume of the blower fan 12 be smaller than that during forward rotation. By reducing the air volume, the humidifying body 9 can contain more disinfecting substances.

  In addition, by reducing the air volume of the blower fan 12 and blowing air, the indoor humidity can be maintained by the air blown out from the air inlet 3.

  The passage of the sterilizing substance to the humidifying body 9 in this way may be performed intermittently as shown in FIG.

  That is, as in the present embodiment, the passage of the sterilizing substance to the humidifying body 9 is performed for 2 hours and then the suspension for 4 hours is performed three times. In this way, for example, after performing the humidification operation for 8 hours a day in accordance with the daily activities of the consumer, the sterilizing substance is passed through the humidifying body 9 at the time of absence or going to bed, thereby sterilizing the humidifying body 9. Can be performed.

  As the sterilizing substance, for example, the same active species as in the above-mentioned prior document is supplied to the humidifying body 9, and thereby the sterilizing with the humidifying body 9 is performed.

  As a result, it is possible to suppress odor generated at the start of operation of the humidifier 1 or during operation.

  In the present embodiment, since the operation time is counted by the integration timer 19 even in the first operation mode 17, even when the first operation mode 17 is switched to the second operation mode 18, The operation time is accumulated, and the humidifying body 9 can be sterilized at an appropriate timing.

  As described above, the control unit 16 includes the operation time determination means 20 for determining that the humidification operation time has exceeded a predetermined time when the humidification operation is stopped, and the humidifier when the operation time exceeds the predetermined time. 9 is provided with the sterilization operation means 21 for passing the sterilizing substance, so that when the humidification operation is stopped, the operation time determination means 20 determines that the humidification operation time has exceeded a predetermined time. The fungus operation means 21 allows the disinfecting substance to pass through the humidifying body 9, thereby suppressing the growth of the bacteria and the odor at the start of the next operation and during the operation.

  The humidifying device 1 includes a mixed flow fan that can rotate forward and backward as the blower fan 12, and the sterilization operation means 21 drives the sterilization means 15 when the humidification operation time exceeds a predetermined time. Since the blower fan 12 is rotated in the reverse direction so that air flows from the exhaust port 4 to the humidifier 9 and the intake port 3, the sterilization operation means 21 is used when the humidification operation time exceeds a predetermined time. The sterilizing means 15 is driven, and the blower fan 12 is rotated in the reverse direction so that the sterilizing substance can pass through the humidifying body 9 to suppress the growth of the bacterium, and the odor at the start of the next operation and during the operation. Can be suppressed.

  Further, since the sterilization means 15 is provided in the passage from the humidifying body 9 to the exhaust port 4 in the blower passage 14, a sterilizing substance may be included in the air that has passed through the humidifying body 9 and discharged from the exhaust port 4. In addition, if the blower fan 12 is rotated in the reverse direction, the sterilizing substance can be passed through the humidifying body 9, so that one sterilizing means 15 can be used in two ways. The use frequency of the sterilization means 15 can be increased. That is, the sterilization means 15 can be used effectively.

(Embodiment 2)
The basic part of the present invention has been described as in the first embodiment.

  In the second embodiment, the intake port 3 of the humidifier 1 is provided with a filter 22 for removing dust. For ease of understanding, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As described in the first embodiment, the air inlet 3 sucks air into the main body case 2 during the humidifying operation. However, when the sterilizing substance is allowed to pass through the humidifying body, the air is discharged from the main body case 2 to the air. Will be blown out. That is, when the filter 22 is provided at the intake port 3, it is necessary to separate the air passage.

  Therefore, as shown in FIG. 6, the frame body 23 provided with the filter 22 includes a front side slit 25 and a back side slit 25 so as to form a slit 24 that is long in the horizontal direction alternately from the upper side to the front side and the back side. A shielding plate 27 that connects the end portion 29 of the back slit 26 is provided. In addition, the front side slit 25 and the back side slit 26 are provided with a thickness in the frame body 23 and indicate the respective surfaces of the front side and the back side.

  Further, the distance between the front slits 25 is larger than the height of the front slits 25, and the filters 22 are disposed at least between the adjacent front slits 25 (the filters 22 are disposed outside the front slits 25. May be) Similarly, the interval between the back side slits 26 is made larger than the height of the back side slits 26.

  By doing in this way, in the thickness part of the frame 23, the flow path is open on the upstream side where air flows through the shielding plate 27, and the flow path is narrowed on the downstream side. That is, the front side slit 25 has a tapered shape from the inner side to the outer side of the main body case 2, so that the air in the main body case 2 can be easily collected and blown out. It is hard to put. Similarly, the back-side slit 26 easily puts air into the main body case 2 and hardly blows out air from the main body case 2. That is, in the thickness portion of the frame 23, the air passage can be separated according to the air flow direction. Thereby, it is possible to prevent the dust collected by the filter 22 from being ejected when passing the sterilizing substance to the humidifying body 9.

  That is, when the blower fan 12 is rotated in the reverse direction so that air flows from the exhaust port 4 to the humidifying body 9 and the intake port 3, the dust collected in the filter 22 is not blown away, and the main body case 2 is discharged from the intake port 3. Since it becomes easy to flow air to the outside, the sterilizing substance passes through the humidifying body 9 to suppress the growth of bacteria, and the odor at the start of the next operation and during the operation can be suppressed.

(Embodiment 3)
In the present embodiment, another embodiment of the second embodiment will be described.

  In the second embodiment, the frame body 23 provided with the filter 22 has a front side slit 25 and a back side slit so as to form a front side slit 25 and a back side slit 26 as slits 24 that are alternately long in the horizontal direction from the top to the front side and the back side. The shield plate 27 connecting the end portions 29 of the 26 is provided.

  In the present embodiment, as shown in FIG. 8, the front slit 25 is not provided. Inside the main body case 2, the frame 23 has a shielding plate 27 that is tapered outwardly between the adjacent back side slits 26, and the tip is closed.

  In addition, the frame body 23 is pivotally supported by a rotating shaft 28 in the horizontal direction and rotated outward from the main body case 2.

  By doing in this way, in the thickness part of the frame 23, the flow path is open on the upstream side where air flows by the shielding plate 27, and the flow path is narrowed on the downstream side. Since the back side slit 26 has a tapered shape toward the inside of the main body case 2, it is easy to inject air into the main body case 2, and it is difficult to blow out air from the inside of the main body case 2.

  On the other hand, since the shielding plate 27 is closed on the front side of the frame body 23 without a slit, the air blown out from the inside of the main body case 2 is collected by the shielding plate 27 and pushes the frame body 23 outward. . Since the frame body 23 is pivotally supported by the rotation shaft 28, the frame body 23 is rotated to open a gap with the main body case 2. In this way, air can be discharged to the outside of the main body case 2. That is, when the sterilizing substance is allowed to pass through the humidifying body, the frame body 23 provided at the intake port 3 rotates to blow air from the main body case 2.

  In this way, the air passage can be separated according to the air flow direction in the frame 23 portion. Thereby, it is possible to prevent the dust collected by the filter 22 from being ejected when the sterilizing substance is passed through the humidifier.

  That is, when the blower fan 12 is rotated in the reverse direction so that air flows from the exhaust port 4 to the humidifying body 9 and the intake port 3, the dust collected in the filter 22 is not blown away, and the main body case 2 is discharged from the intake port 3. Since it becomes easy to flow air to the outside, the sterilizing substance passes through the humidifying body 9 to suppress the growth of bacteria, and the odor at the start of the next operation and during the operation can be suppressed.

  As described above, the present invention provides the sterilization means in the air passage from the humidifier to the exhaust port in the main body case, and determines that the humidification operation time has exceeded a predetermined time when the humidification operation is stopped. An operation time determining means and a sterilization operation means for passing the sterilizing substance through the humidifier when the operation time exceeds a predetermined time are provided. For this reason, when the operating time exceeds a predetermined time, the sterilizing substance is passed through the humidifying body, so that the sterilization with the humidifying body is performed.

  Thereby, generation | occurrence | production of the odor at the time of a driving | operation start and a driving | operation can be suppressed.

  Therefore, it is utilized as a humidifier.
