Hereinafter, a humidifier according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a schematic configuration of a humidifier according to Embodiment 1 of the present invention. As shown in FIG. 1, the humidifier 100 includes a main body 6 in which an air air passage 3 in which an inlet 1 and an outlet 2 are communicated is formed. The air air passage 3 is provided with a sirocco fan 4 that is a blowing means. The sirocco fan 4 generates an air flow from the air inlet 1 toward the air outlet 2 in the air air passage 3.

The air air passage 3 is provided with an air cleaning filter 21, a humidity sensor 22, and a water tank 7 in order from the suction port 1 side. The main body 6 is provided with water supply means 11 for supplying water to the water tank 7. The water supply means 11 has a water supply connection port 8 formed in the main body 6, a pipe 5 extending from the water supply connection port 8 toward the water supply tank 7, and a water supply valve 9 for opening and closing the pipe 5. By opening the water supply valve 9, water is supplied from one end of the pipe 5 to the water supply tank 7.

A humidifying element 17 for humidifying the air passing through the air air passage 3 is provided in the air air passage 3 below the water supply tank 7. A plurality of holes (not shown) for dispersing the water supplied by the water supply means 11 in the humidifying element 17 are formed on the bottom surface of the water supply tank 7. The water supplied from the water supply tank 7 permeates and diffuses into the humidifying element 17. The air passing through the air air passage 3 is humidified by the water vaporized by the humidifying element 17. The water that has not been vaporized by the humidifying element 17 flows to the drainage tank 12 provided below the humidifying element 17. A drain port 14 is formed on the bottom surface of the drain tank 12. The drainage port 14 is connected to the drainage connection port 13 provided in the main body 6 to constitute the drainage means 15.

The main body 6 is provided with an operation means 20 that can perform an operation stop selection operation of the humidifier 100 and a control unit 19 that controls the operation of the sirocco fan 4 and the water supply valve 9 based on information from the humidity sensor 22. It is done. The sirocco fan 4 may be provided on the upstream side of the humidifying element 17 or may be provided on the downstream side of the humidifying element 17. Further, it may be provided outside the main body 6 and connected to the duct. Also, when provided outside the main body 6, it may be provided upstream from the main body 6 or may be provided downstream from the main body 6. The humidity sensor 22 may be provided outside the main body 6. Further, the operation means 20 may be an operation switch provided in the main body 6 instead of the remote controller as shown in FIG.

Next, an example of the operation when the user operates the operation means 20 to drive the humidifier 100 will be described. FIG. 2 to FIG. 4 are flowcharts illustrating an example of a control operation by the control unit 19 of the humidifier 100 according to the first embodiment. Note that the operation of the humidifying device 100 performed by the user operating the operating means 20 is performed by operating a humidifying button (not shown) provided in the operating means 20 and provided in the operating means 20. May be implemented by the scheduled function. Note that the steps shown in the following drawings show the judgment and control performed by the control unit 19.

After turning on the power to the humidifier 100, in step S21, the “drying timer” is set to the initial time, the “wetting timer” is set to the clear stop, and the “forced air blow mode start time” is set to the specified time. Is done.

In the first embodiment, the initial time of the “drying timer” is set to 2 hours. The clear stop means stopping the count after setting the timer count to zero. Further, the prescribed time of “forced air blow mode start time” is set to 48 hours.

Here, when the “drying timer” is equal to or greater than the initial time, it is determined that the humidifying element 17 is completely dried. When the “drying timer” is less than the initial time, it is determined that the humidifying element 17 is wet. The initial time set in the “drying timer” is a value determined in advance, but may be changed by the operation means 20. In step S21, since the “drying timer” is set to the initial time of 2 hours, “drying timer” = initial time, and it is determined that the humidifying element 17 is completely dry.

Also, the “wetting timer” counts the time during which the humidifying element 17 is wet. Further, the specified time set in the “forced air blowing mode start time” is a reference for determining the duration of the wet state of the humidifying element 17 and a reference for determining whether to forcibly enter the air blowing mode. It is time to become. The specified time set in the “forced air blowing mode start time” is a value determined in advance, but may be changed by the operation means 20.

In step S22, the water supply valve 9 is closed and the sirocco fan 4 is stopped. In the following description, the control mode in which the water supply valve 9 is closed and the sirocco fan 4 is operated is referred to as an air supply mode, and the control mode in which the water supply valve 9 is opened and the sirocco fan 4 is rotated is referred to as a humidification mode.

In step S23, it is determined by the operation means 20 whether the user has operated the humidifier 100. When the operation of the humidifier 100 is being performed, the process proceeds to step S24. On the other hand, when the operation of the humidifier 100 has not been performed, the process returns to step S22.

In step S24, the control mode of the humidifier 100 is set to the air blowing mode. In step S25, the sirocco fan 4 is rotated. In step S <b> 26, it is determined whether or not the user has stopped the humidifying device 100 by the operation unit 20. When the stop operation of the humidifier 100 has been performed, the process returns to step S22. On the other hand, if the stop operation of the humidifier 100 has not been performed, the process proceeds to step S27.

In step S27, it is determined whether a certain time has elapsed since the air blowing mode was set. In the first embodiment, the predetermined time is 5 minutes. If the predetermined time has not elapsed, the process returns to step S26. On the other hand, if the predetermined time has elapsed, the process proceeds to step S28. The determination in step S27 is for the purpose of waiting for a certain time until the detected value of the humidity sensor is stabilized, and the time is adjusted according to the installation environment of the humidifier 100, and there is no waiting time, that is, a certain time. It can be 0.

In step S28, it is determined whether the control mode is the humidification mode or the ventilation mode. If it is a humidification mode, it will progress to step S201, and if it is a ventilation mode, it will progress to step S211. Steps S201 to S207 are operations in the humidification mode, and steps S211 to S218 are operations in the air blowing mode.

In step S201, it is determined whether the humidity detected by the humidity sensor 22 is equal to or higher than “target humidity + 5%”. If the detected humidity is equal to or higher than “target humidity + 5%” that is the first specified humidity, the control mode is changed to the air blowing mode in step S202, and the process returns to step S28. On the other hand, if the detected humidity is less than “target humidity + 5%”, the process proceeds to step S203. Note that the target humidity is set in advance by the user using the operation means 20.

In step S203, it is determined whether the “wetting timer” has passed the “forced air blowing mode start time”. If the “wetting timer” has exceeded the “forced air blow mode start time” or longer, the process proceeds to step S202. On the other hand, if the “wetting timer” is less than the “forced air blow mode start time”, the process proceeds to step S204. When step S203 is reached for the first time after step S21, the “wetting timer” is cleared and stopped in step S21, and the process proceeds to step S204.

In step S204, the “wet timer” starts counting, and the process proceeds to step S205. In step S211 described later, when the “drying timer” is longer than the specified time, that is, when the humidification element 17 is determined to be completely dry, the process enters step S204 for the first time, and after step S21, the process proceeds to step S204 first. If reached, the “wet timer” will start counting from zero. If the “drying timer” is less than the specified time, that is, if the humidifying element 17 is wet, the process enters the step S204, and the “wetting timer” continues counting.

In step S205, the water supply valve 9 is opened while the sirocco fan 4 is rotating. Thereby, water is supplied from the water supply port 10 to the water supply tank 7. Then, water is supplied to the humidifying element 17 through the water supply tank 7. At this time, since the sirocco fan 4 is rotating, the air sucked from the suction port 1 passes through the humidifying element 17 in the air air passage 3, flows to the outlet 2, and is blown into the room. By passing the air through the humidifying element 17, the water on the humidifying element 17 is evaporated and evaporated, and the humidified air can be supplied to the room.

In the humidifying device 100 according to the first embodiment, tap water containing chlorine is directly supplied from the water supply means 11 to the humidifying element 17 so that mold and bacteria are unlikely to occur on the humidifying element 17. It has become. In addition, the water supply capacity of the water supply means 11 is such that it can supply an amount of water about three times the amount of evaporated water during the humidifying operation, and the density of the holes formed in the volume of the water supply tank 7 and the bottom surface of the water supply tank 7 is It is assumed that it is designed not to overflow from the water tank 7. In addition, if the bottom surface of the water supply tank 7 is clogged and overflows, leakage of water to the outside of the machine can be prevented by adopting a structure that receives the overflowed water in the drain tank 12.

In the humidification mode, the remaining water of the humidified feed water that has not been vaporized by the humidification element 17 flows to the drainage tank 12. The remaining water is drained from a drain port 14 formed in the bottom surface of the drain tank 12 through a drain connection port 13 provided in the main body 6. In addition, in the humidifying device 100 according to the first embodiment, since the residual water that has not been vaporized by the humidifying element 17 is not circulated to the humidifying element 17, mold and germs are caused by the residual water remaining in the machine. It is hard to generate the trouble that breeds. In addition, since the residual water is not reused, the chalk component is not concentrated.

In step S206, the “drying timer” is cleared and the process proceeds to step S207. In step S207, it is determined by the operation means 20 whether or not the user has stopped the humidifying device 100. If the operation of stopping the humidifier 100 has been performed, the process proceeds to step S22. On the other hand, if the stop operation of the humidifier 100 has not been performed, the process returns to step S201.

Next, the operation when it is determined in step S28 that the mode is the blower mode will be described. In step S211, it is determined whether the “drying timer” is 2 hours or longer. If the “drying timer” is 2 hours or longer, the “wetting timer” is cleared and stopped in step S212, and the process proceeds to step S214. On the other hand, if the “drying timer” is less than 2 hours, the process proceeds to step S213.

In step S213, it is determined whether the “wetting timer” has passed the “forced air blowing mode start time”. If the “wetting timer” has passed the “forced air blow mode start time” or longer, the process proceeds to step S216. On the other hand, if the “wetting timer” is less than the “forced air blow mode start time”, the process proceeds to step S214.

In step S214, it is determined whether the humidity detected by the humidity sensor 22 is equal to or lower than “target humidity—5%” which is the second specified humidity. If the detected humidity is “target humidity−5%” or less, the control mode is changed to the humidification mode in step S215, and the process returns to step S28. On the other hand, if the detected humidity exceeds “target humidity−5%”, the process proceeds to step S216. Here, the second specified humidity is set to “target humidity−5%”, which is lower than the first specified humidity “target humidity + 5%”. This is to suppress the occurrence of so-called chattering in which the control mode is frequently switched between the humidification mode and the air blowing mode when it moves up and down. That is, as long as the occurrence of chattering can be suppressed, the magnitude relationship between the first specified humidity and the second specified humidity does not matter. For example, when the first specified humidity and the second specified humidity are set to the “target humidity” that is the same humidity, the operation in the humidification mode is continued for a certain time when the process proceeds from step S201 to step S202. If the mode is changed to the air blowing mode after that, chattering can be suppressed. Further, when the process proceeds from step S214 to step S215, if the operation in the air blowing mode is continued for a certain time and then the humidification mode is changed, the occurrence of chattering can be suppressed. An example of the fixed time for continuing the humidification mode and the air blowing mode is 30 minutes.

In step S216, the water supply valve 9 is closed while the sirocco fan 4 is rotated, and the process proceeds to step S217. In addition, water supply from the water supply port 10 to the water supply tank 7 stops because the water supply valve 9 was closed in this step S216. That is, the water supply to the humidifying element 17 stops.

As a result, as the vaporization and evaporation of the humidifying element 17 progresses, the humidifying element 17 is dried, and the humidified air is gradually not supplied to the living room, so that excessive humidification is suppressed. In addition, in the humidification apparatus 100 concerning this Embodiment 1, since the air purifying filter 21 is equipped, it can be said that air purifying operation is implemented at the time of ventilation mode.

In step S217, the “drying timer” starts counting, and the process proceeds to step S218. In addition, when switching from humidification mode to ventilation mode and entering this step S217 for the first time, since the clear stop of step S206 is passed, the "drying timer" will start counting from zero. When the step S217 is entered while the air blowing mode is being continued, the “drying timer” continues counting.

In step S218, it is determined by the operation means 20 whether the user has stopped the humidifying device 100. If the operation of stopping the humidifier 100 has been performed, the process proceeds to step S22. On the other hand, when the operation of stopping the humidifier 100 has not been performed, the process returns to step S211.

As described above, the humidifying device 100 according to the first embodiment forcibly changes to the air blowing mode when the “wetting timer” exceeds the “forced air blowing mode start time” in step S203. Therefore, even if the humidification element 17 continues to be wet due to a long-term operation in the humidification mode, the humidification element 17 is given priority by giving priority to the air blowing mode based on the “forced air blowing mode start time”. It is dried regularly. Thereby, even if it is a case where a humidification driving | operation is not stopped over a long period of time, the humidification element 17 can be dried and the proliferation of mold | fungi and various germs, and generation | occurrence | production of an odor can be suppressed.

Further, when the mode is forcibly changed to the air blowing mode, it is determined in step S211 that the “drying timer” is 2 hours or more, and in step S214, the detected humidity is determined to be equal to or lower than the target humidity −5%. Thus, the return to the humidification mode is performed. Therefore, it is possible to suppress the target space from being dried too much by continuing the air blowing mode.

Also, when the detected humidity is determined to be the target humidity + 5% or more in step S201, it is changed to the air blowing mode, so that it is possible to suppress the target space from being excessively humidified.

Also, it is determined whether or not the humidifying element 17 is completely dried by counting the “drying timer”. In the state where the humidifying element 17 is completely dried, the “wetting timer” is a clear stop. Therefore, after the transition to the next humidifying mode, the operation of the humidifying mode is prevented at least during the “forced air blowing mode start time”. In this way, it is possible to continue humidification of the target space.

Embodiment 2. FIG.
FIG. 5 to FIG. 7 are flowcharts illustrating an example of a control operation performed by the control unit 19 of the humidifier 100 according to the second embodiment. Items that are not particularly described are the same as those in the first embodiment, and the same functions and configurations are described using the same reference numerals. Also, the description of the same functions and configurations as those of the first embodiment is omitted.

The difference from the first embodiment is that the humidification mode and the air blowing mode are not determined by comparing the humidity sensor 22 and the target humidity but according to the instruction by the operation means 20. Is a point. Hereinafter, steps that are different from the above embodiment will be described.

In step S23, when the operation of the humidifier 100 is performed, in step S34, the air blowing mode or the humidifying mode is set according to the setting of the operation means 20, and the process proceeds to step S25.

In step S25, the sirocco fan 4 is rotated, and the process proceeds to step S28. If it is determined in step S28 that the humidification mode is selected, the control proceeds to the humidification mode shown in FIG. In step S <b> 301, it is determined whether there is an operation for setting the air blowing mode from the operation unit 20. If there exists operation which sets to ventilation mode, it will progress to step S202. On the other hand, if there is no operation which sets to ventilation mode, it will progress to step S203.

Further, in the control in the air blowing mode shown in FIG. 7, in step S211, it is determined that the “drying timer” is 2 hours or longer, and in step S212, the “wetting timer” is cleared and stopped, or in step S213. If the “humidity timer” is less than the “forced air blowing mode start time”, it is determined in step S314 whether there is an operation for setting the humidification mode from the operation means 20. If there is an operation for setting the humidification mode, the process proceeds to step S215. On the other hand, if there is no operation which makes humidification mode, it will progress to step S216.

As described above, in the humidifying device 100 according to the second embodiment, even when the humidifying mode is directly set by the operating means 20, when the humidifying element 17 continues the wet state for a long time, Since it is possible to prioritize the air blowing mode, it is possible to suppress the growth of mold and bacteria and the generation of odors.

In addition, although the humidification apparatus 100 concerning this Embodiment 2 was comprised so that the ventilation mode and the humidification mode could be directly set by the operation means 20, the detection humidity and target of the humidity sensor 22 described in Embodiment 1 were set. The “automatic mode” that automatically switches between the air blowing mode and the humidifying mode may be selected by the operation means 20 by comparison with the humidity.

Embodiment 3 FIG.
8 to 10 are flowcharts illustrating an example of a control operation by the control unit 19 of the humidifying apparatus 100 according to the third embodiment. Items that are not particularly described are the same as those in the first embodiment, and the same functions and configurations are described using the same reference numerals. In addition, description of the same functions and configurations as those of the first embodiment is omitted.

The difference from the first embodiment is that when the humidifying element 17 continues in a wet state for a long time, the “forced air blowing mode start time” can be extended by comparing the detected humidity and the target humidity, that is, the operation in the humidifying mode. Is that it can be extended. Hereinafter, steps that are different from the above embodiment will be described.

In the control in the humidification mode shown in FIG. 9, when the “wetting timer” is equal to or greater than the “forced air blowing mode start time” in step S203, the detected humidity of the humidity sensor 22 is the first specified humidity in step S408. It is determined whether the target humidity is equal to or higher than “target humidity−10%”, which is a third specified humidity smaller than the humidity. If the detected humidity is “target humidity−10%” or more, the control mode is changed to the air blowing mode in step S202, and the process returns to step S28. On the other hand, if the detected humidity is less than “target humidity−10%”, the process proceeds to step S409. In step S409, correction for extending the “forced air blowing mode start time” by one hour is performed, and the process proceeds to step S204.

In the control in the air blowing mode shown in FIG. 10, when the “drying timer” has reached the specified time in step S211, the “forced air blowing mode start time” is initialized to the specified time in step S419, and step S212. Proceed to

According to the third embodiment, when the humidity detected by the humidity sensor 22 is less than “target humidity−10%” and the humidity is lower than the target humidity, the “forced air blowing mode start time” is set. It is possible to continue the operation of the “humidification mode” by performing a correction for extending the value. Accordingly, it is possible to prevent the comfort space from being impaired due to the forced change to the air blowing mode even though the target space has a low humidity. If the humidity of the target space satisfies the condition shown in step S201 or if the condition shown in step S408 is satisfied, the humidifying element 17 is dried by changing to the air blowing mode, so that mold and bacteria propagate, and odor Can be suppressed. Note that the threshold value “target humidity−10%” may be changeable by the operation means 20.

Embodiment 4 FIG.
FIG. 11: is a figure which shows schematic structure of the humidification apparatus 100 concerning Embodiment 4 of this invention. FIGS. 12-14 is a flowchart which shows an example of the control action by the control part 19 of the humidification apparatus 100 concerning Embodiment 4. FIG. Items that are not particularly described are the same as those in the first embodiment, and the same functions and configurations are described using the same reference numerals. In addition, description of the same functions and configurations as those of the first embodiment is omitted.

The difference from the first embodiment is that a temperature sensor 51 is provided in the air air passage 3 as shown in FIG. Further, when the humidifying element 17 has been in a wet state for a long time, the “forced air blowing mode start time” can be extended by comparing the detected temperature with the detected temperature before the specified time, that is, the operation in the humidified mode can be extended. It is in the point. The temperature sensor 51 detects the temperature in the air air passage 3 and the signal is input to the control unit 19. The temperature sensor 51 may be provided in a duct connected to the upstream side of the main body 6. Hereinafter, steps that are different from the above embodiment will be described.

In the control in the humidifying mode shown in FIG. 13, when the “wetting timer” becomes equal to or longer than the “forced air blowing mode start time” in step S203, the current detected temperature detected by the temperature sensor 51 in step S508 is used. It is determined whether there is a difference of 1 ° C. or more from the detected temperature 30 minutes ago. If the difference between the detected temperatures is 1 ° C. or more, that is, if the temperature is in an increasing trend and the relative humidity is in a decreasing trend, the process proceeds to step S409 and the “forced air blow mode start time” is extended. Is done. On the other hand, if the detected temperature difference is less than 1 ° C., that is, if it is determined that the temperature does not tend to increase and the relative humidity does not tend to decrease, the control mode is changed to the air blowing mode in step S202. The process returns to step S28.

In the humidifier 100 according to the fourth embodiment, when the temperature detected by the temperature sensor 51 tends to increase, that is, the relative humidity tends to decrease, and comfort may be impaired, the “forced air blow mode start time” Is performed, the operation in the “humidification mode” can be continued. Thereby, although the relative humidity of the target space tends to decrease, it is possible to prevent the comfort mode from being impaired due to the forced change to the air blowing mode. If the humidity of the target space satisfies the condition shown in step S201 or does not satisfy the condition shown in step S508, the humidifying element 17 is dried by the change to the air blowing mode, and the growth of mold and germs, and Odor generation can be suppressed. It should be noted that the difference between the detected temperatures serving as the determination criteria may be arbitrarily changed by the operation means 20.

In addition, in the humidifier 100 according to the fourth embodiment, the correction for extending the “forced air blow mode start time” is performed by the time change of the temperature detected by the temperature sensor 51, but the current temperature sensor 51 simply detects. The “forced air blowing mode start time” may be extended based on the detected temperature. Specifically, when the current detected temperature is less than 15 ° C., it is determined that the temperature of the target space thereafter increases and the relative humidity may decrease, and the “forced air blow mode start time” is extended by 1 hour. In the case where the current detected temperature is 15 ° C. or higher, there is a control in which it is determined that the relative humidity is not easily lowered and the comfort is not impaired, and the mode is changed to the air blowing mode. The detected temperature serving as a determination criterion may be arbitrarily changed by the operation unit 20.

Further, in the humidifying device 100 according to the fourth embodiment, the “forced air blowing mode start time” is corrected by the time change of the temperature sensor 51, but the “forced air blow mode start time” is corrected by the time change of the detected humidity of the humidity sensor 22. The “blow mode start time” may be extended. Specifically, if the current detected humidity is 3% or more lower than the previous detected humidity, which is 30 minutes before, it is determined that the relative humidity of the target space may subsequently decrease, The “blow mode start time” is extended by 1 hour. On the other hand, if the current detected humidity has not fallen by more than 3% compared to the detected humidity 30 minutes ago, it will be judged that there will be no significant decrease in relative humidity and comfort will not be impaired, and the mode will be changed to the blower mode. Let The difference in the detected humidity that becomes the determination criterion may be arbitrarily changed by the operation means 20.

Embodiment 5 FIG.
FIGS. 15 to 17 are flowcharts illustrating an example of a control operation performed by the control unit 19 of the humidifying apparatus 100 according to the fifth embodiment. Items that are not particularly described are the same as those in Embodiment 3, and the same functions and configurations are described using the same reference numerals. Also, the description of the same functions and configurations as those in Embodiment 3 is omitted.

The difference from the third embodiment is that the “forced air blow mode start time” after the driving operation is extended when the humidifying device 100 is stopped in a state where the humidifying element 17 has been in a wet state for a long time and then the driving operation is performed. This is a possible point. That is, at the start of operation of the humidifier 100, even when the humidifying element 17 has reached the specified time, the humidifying element 17 is operated in the humidifying mode. Hereinafter, steps that are different from the third embodiment will be described.

In step S23, when the operation of the humidifier 100 has been performed, in step S71, the “wetting timer” and the “forced air blowing mode start time” are compared. If the “wetting timer” is equal to or greater than the “forced air blowing mode start time”, the process proceeds to step S72. If the “wetting timer” is less than the “forced air blowing mode start time”, the process proceeds to step S24.

In step S72, the control unit 19 sets a value obtained by adding 1 hour to the current value of the “wetting timer” for the “forced air blowing mode start time”, and performs a correction for extending the “forced air blowing mode start time”. The process proceeds to step S24.

According to the fifth embodiment, when the user performs an operation of the humidifying device 100, even when the “wetting timer” is equal to or longer than the “forced air blowing mode start time”, the user operation is given priority. The “forced air blow mode start time” is extended. Therefore, when the operation of the humidifying device is resumed, according to the count of the “humidity timer”, the operation in the humidification mode can be performed with priority given to the user operation. Thereby, it becomes possible for the humidifying device 100 to suppress the growth of mold and bacteria and the generation of odor while making it difficult for the user to feel uncomfortable that the humidifying device does not accept the operation.

In addition, in the humidifying device 100 according to the fifth embodiment, correction is made to extend the “forced air blowing mode start time” during the operation of the humidifying device 100, but there has been an operation for changing the control mode by the operating means 20. In this case, the “forced air blowing mode start time” may be extended. Specifically, when there is a change operation from the operation means 20 to the humidification mode during operation in the air blowing mode, the “forced air blowing mode start time” is extended by 1 hour.

In addition, the initial time, the specified time, the target temperature, and the specified humidity described in each of the above embodiments may be stored in advance in a storage unit (not shown). The storage unit is provided in the control unit 19 or the operation unit 20, for example.

The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
