Description

  The present invention relates to a humidifier and a control method thereof.

As a conventional humidifier, water is supplied to a humidifying element from a water supply source (for example, tap water), and the air supplied to the ventilation path of the humidifying element is passed through a moisture permeable membrane (for example, a hydrophobic porous membrane). Some are humidified.
The moisture permeable membrane does not allow passage of water but allows passage of water vapor.
In such a humidifier, dust, scale (calcium, etc.) contained in the supplied water does not pass through the moisture permeable membrane, and humidifies the air supplied to the ventilation path without contaminating it. Can do.

On the other hand, if the water supplied to the humidifying element is not discharged and the water continues to be stored in the humidifying element for a long period of time, dust, scales, etc. adhere to the moisture permeable membrane, and the humidifying performance decreases, Mold, bacteria, etc. breed and bad odor will be generated.
Therefore, in the conventional humidifier, when the drainage system is connected to the humidifying element and the humidification operation is stopped, the drainage operation for discharging the stored water is performed (see Patent Document 1).
Further, in the conventional humidifier, the humidifying operation is forcibly stopped at a preset time interval, and a draining operation for discharging the stored water is performed (see Patent Document 2).

JP-A-8-247509 (paragraphs [0031]-[0036]) Japanese Patent Laid-Open No. 10-288362 (paragraphs [0019]-[0024])

As the time interval of the draining operation is shorter, the decrease in humidification performance is suppressed and the generation of malodor is suppressed, but the consumption of water increases as the number of draining operations increases.
In addition, as the amount of drainage in a single drainage operation increases, the decrease in humidification performance is suppressed and the generation of malodor or the like is suppressed. However, the consumption of water increases as the amount of drainage increases.
That is, the drainage operation needs to be performed with an appropriate time interval and drainage amount.

  However, when the drainage operation is performed when the humidification operation is stopped as in the conventional humidification device, the humidification operation is, for example, a heating operation of an air conditioner that operates continuously for 24 hours. When linked, there is a problem that the humidifying operation is not stopped for a long time and the draining operation is not performed at an appropriate time interval.

The quality of the water supplied to the humidifying element varies depending on, for example, the region.For example, when water with a high concentration of scale is supplied to the humidifying element, the amount of scale attached to the moisture permeable membrane increases. , The reduction in humidification performance is promoted.
Further, during the humidifying operation, water is supplied from the water supply source to supplement the consumption of the water stored in the humidifying element. For example, when the frequency of the humidifying operation is high, the scale component adhering to the moisture permeable membrane Increases and the reduction in humidification performance is promoted.
That is, the appropriate time interval and amount of drainage for the drainage operation depend on the water quality, the frequency of the humidification operation, and the like.

  However, when the time interval of drainage operation and the amount of drainage are set in advance as in the case of conventional humidifiers, differences in water quality, frequency of humidification operations, etc. are not taken into account and appropriate for each humidifier. There was a problem that proper drainage operation was not set.

The present invention has been made to solve the above-described problems, and provides a humidifier capable of performing an appropriate drainage operation for each humidifier.
Moreover, the control method of the humidifier which can perform appropriate drainage operation | movement to each humidifier is obtained.

The humidifier according to the present invention has a ventilation path provided with a moisture permeable membrane, a humidifying element that humidifies the air supplied to the ventilation path via the moisture permeable membrane, and a drain valve, A drainage system for discharging water from the humidifying element through the drainage valve, a setting unit for setting a drainage time interval and a drainage amount, and opening the drainage valve based on the set drainage time interval, A control unit having a control unit that closes the drain valve based on a set amount of drainage, and a determination unit that determines the degree of deterioration of the humidifying element , the setting unit including the humidifying element In accordance with the degree of deterioration , at least one of the drainage time interval and the drainage amount is updated.

  The humidifier according to the present invention includes a control unit that sets a drain time interval and a drain amount, and has a setting unit that updates at least one of the drain time interval and the drain amount. The action can be performed.

(Operation of humidifier)
Below, the effect | action of the humidification apparatus which concerns on Embodiment 1 is demonstrated.
In the humidifier according to Embodiment 1, the humidifying operation is forcibly stopped at every drain time interval set by the setting unit 7a, and the drain operation of the humidifying element 2 is performed only for the drain time set by the setting unit 7a. Is done.
Therefore, the water whose scale concentration has increased in accordance with the humidifying operation is periodically replaced with water having a low concentration for the scale, so that the scale component adheres to the moisture permeable membrane and the humidifying performance of the humidifying element 2 is improved. Decrease is suppressed.
Moreover, it is possible to suppress the generation of malodors and the like due to the growth of mold, bacteria, and the like.

And the humidification apparatus which concerns on Embodiment 1 is provided with the setting part 7a which updates at least any one of a drainage time interval and drainage time.
Therefore, the drainage time interval and drainage time according to the water quality, the frequency of the humidification operation, etc. are set by the user, the maintenance worker, etc. operating the selection unit 7c, and the humidification operation appropriate for each humidifier 1 is set. It can be performed.

In addition, in the humidifier which concerns on Embodiment 1, although the setting part 7a has set both the drainage time interval and the drainage time, you may set only either one of a drainage time interval or drainage time.
When the setting unit 7a sets both the draining time interval and the draining time, a further appropriate humidifying operation can be performed on each humidifying device 1 by a synergistic effect.

(Modification)
In the humidifying device 1, the humidifying element 2 is a laminate of the humidifying functional bodies 2a, but the humidifying element 2 may be a humidifying element having another structure.
Humidifying elements having other structures include humidifying elements in which a large number of pipe-shaped moisture permeable membranes are arranged in parallel, for example, humidifying elements in which a large number of pipe-shaped PTFE (polytetrafluoroethylene) are arranged in parallel. included.
When the humidifying element 2 is a laminate of the humidifying functional bodies 2a, a structure in which the water retaining layer and the air feeding layer are formed densely can be easily obtained.

In the humidifier 1, the drain valve 5a is a switching valve, but the drain valve 5a may be a regulating valve that adjusts pressure and flow rate.
For example, when the drain container 3 is shared with other devices, the controller 7b causes the drain valve 5a to open, that is, the flow rate of water discharged from the drainage system 5, and the water overflows from the drain container 3. You may control so that it may not exist.
In such a case, for example, the drainage amount of the drainage system 5 is detected by providing a flow meter in the drainage system 5, and the drainage amount itself is set in the setting unit 7a instead of the drainage time.
The control unit 7b may divert the detection result of the drainage amount to other control.
When the drain valve 5a is a switching valve, the device configuration is simplified.

In the humidifier 1, the selection unit 7c is a changeover switch, but the selection unit 7c may be other selection means such as a software interface.
Moreover, the selection part 7c is not provided, but a user, a maintenance worker, etc. may input arbitrary drainage time intervals and drainage time into an input part.
When the selection unit 7c is provided, erroneous input by a user, a maintenance worker, or the like is prevented.

In the humidifying device 1, the controller 7 is provided in the humidifying device 1, but a part or all of the controller 7 may be provided in another device remote from the humidifying device 1.
In particular, when the selection unit 7c is provided in another remote device, the operation of the selection unit 7c can be performed from a remote location. For example, when performing centralized management, a user, a maintenance worker, etc. However, the workability in selecting the drainage time interval and drainage time is improved.

Embodiment 2. FIG.
A humidifier according to Embodiment 2 will be described.
In addition, below, the description which overlaps or resembles the humidification apparatus which concerns on Embodiment 1 is simplified or abbreviate | omitted suitably.
(Configuration of humidifier)
Below, the structure of the humidification apparatus which concerns on Embodiment 2 is demonstrated.
FIG. 6 is a diagram illustrating a configuration of the humidifier according to the second embodiment.
As shown in FIG. 6, the humidifier 11 includes a humidifying element 2, a drain container 3, a water supply system 4, a drainage system 5, a blower 6, a controller 17, and a measuring unit 19.
The controller 17 corresponds to “control means” in the present invention.

The measuring means 19 passes through the humidifying element 2, a detector 19 a that detects the temperature on the upstream side of the air that passes through the humidifying element 2, a detector 19 b that detects the temperature on the downstream side of the air that passes through the humidifying element 2. And a detector 19c for detecting the flow rate of the air to be detected.
The detector 19c is not provided, and the flow rate of the air passing through the humidifying element 2 may be calculated from the specifications of the blower 6, the motor rotation speed, and the like.

The controller 17 is connected to the water supply valve 4a, the drain valve 5a, the blower 6, and the measuring means 19.
The controller 17 includes a setting unit 17a, a control unit 7b, and a determination unit 17d.
The setting unit 17a sets a drain time interval and a drain time.

FIG. 7 is a diagram illustrating data stored in the setting unit of the humidifier according to the second embodiment.
As shown in FIG. 7, the setting unit 17a stores data in which combinations of drainage time intervals and drainage times are tabulated.
The combinations of drainage time intervals and drainage times are ranked in the order of decreasing water consumption and are tabulated.
In addition, although the case where a rank is 1-10 is shown in FIG. 7, it is not limited to such a case.

The determination part 17d calculates | requires humidification amount from the difference of the temperature detected by the detector 19a and the detector 19b, and the flow volume of the air detected by the detector 19c.
For the humidification amount M [kg / hr], the temperature difference is ΔT [K], the air flow rate is Q [kg / hr], the constant-pressure specific heat of air is C [J / kgK], and the latent heat of water evaporation is L Assuming that [J / kg] and the difference in sensible heat between the upstream side and the downstream side of the humidifying element 2 is equal to the amount of latent heat of vaporization taken away by water during humidification, it is approximated by the following (Formula 1).

The determination part 17d memorize | stores the reference | standard humidification amount preset for every integration time of humidification operation | movement.
The determination unit 17d measures the accumulated time of the humidifying operation of the humidifying device 11.
When the humidifying device 11 can change the output of the humidifying operation such as the motor rotation speed of the blower 6, the determination unit 17 d calculates an integrated time in which the time change of the output is corrected.
The accumulated time is reset when the humidifying element 2 is replaced.
The determination unit 17d identifies the reference humidification amount corresponding to the measured accumulated time, compares the humidification amount estimated in (Equation 1), that is, the actually measured humidification amount, and the identified reference humidification amount, The degree of deterioration of the humidifying element 2 is determined.
The setting unit 17a updates the drainage time interval and the drainage time according to the determination result of the deterioration degree in the determination unit 17d.

(Control flow of humidifier)
Below, the control flow of the humidification apparatus which concerns on Embodiment 2 is demonstrated.
FIG. 8 is a diagram illustrating a control flow of the humidifier according to the second embodiment.
The control flow can be changed as appropriate.
Steps 801 to 807 and 812 to 815 are the same as steps 501 to 507 and 509 to 512 in FIG.

In step 808, the setting unit 17a sets a drain time interval and a drain time, and proceeds to step 809.
The drainage time interval and drainage time are the drainage time interval and drainage time set during the immediately preceding humidification operation.
The setting unit 17a is the smallest when the accumulated time of the humidifying operation of the humidifying device 11 is 0 or when the accumulated time of the humidifying operation of the humidifying device 11 after the humidifying element 2 is replaced is 0. A rank is selected, and a drainage time interval and drainage time of a combination corresponding to the rank are set.

In step 809, the determination unit 17d compares the elapsed time from the previous determination (hereinafter, “post-determination elapsed time”) with a predetermined determination time interval (hereinafter, “determination time interval”), and after the determination If the elapsed time exceeds the determination time interval, the process proceeds to step 810; otherwise, the process proceeds to step 812.
When the determination time interval is set short, the next update is performed before the improvement effect of the deterioration degree of the humidifying element 2 due to the update of the drainage time interval and the drainage time is exhibited.
For this reason, the determination time interval needs to be set to a time interval at which the effect of improving the degree of deterioration of the humidifying element 2 due to the updated drainage time interval and drainage time is exhibited.

In step 810, the determination unit 17d determines whether the degree of deterioration of the humidifying element 2 is large. If the degree of deterioration is large, the process proceeds to step 811. If not, the process proceeds to step 812.
The determination unit 17d compares the measured humidification amount with the reference humidification amount, and determines that the degree of deterioration of the humidifying element 2 is large when the measured humidification amount exceeds the reference humidification amount.

  In step 811, the setting unit 17 a raises the rank to be selected to the side where water consumption increases from the rank corresponding to the combination of the drainage time interval and drainage time set in step 808, and corresponds to that rank. The drainage time interval and drainage time are updated to the drainage time interval and drainage time of the combination, and the process proceeds to Step 812.

(Operation of humidifier)
Below, the effect | action of the humidification apparatus which concerns on Embodiment 2 is demonstrated.
In the humidifier according to Embodiment 2, the setting unit 17a automatically sets an appropriate drainage time interval and drainage time without involving a person.
Therefore, it is not necessary for a user, a maintenance worker or the like to select a drain time interval and a drain time.

Moreover, in the humidification apparatus which concerns on Embodiment 2, the setting part 17a ranks and memorize | stores the combination of drainage time interval and drainage time, and sets drainage time interval and drainage time by selecting a rank. .
Therefore, the processing of the setting unit 17a is simplified.

In the humidifying device according to Embodiment 2, the setting unit 17a sets the drainage time interval and the drainage time based on actual measurement.
Therefore, a more appropriate drainage time interval and drainage time are set as compared with a case where the user, maintenance worker, or the like selects.

(Modification)
In the humidifier 11, the determination unit 17 d compares the elapsed time after determination with the determination time interval, but the determination unit 17 d is set in advance with the accumulated time of the humidification operation or the drainage operation from the previous determination. You may compare with the time interval of the determination with respect to the integration time of humidification operation | movement or drainage operation | movement.
In such a case, the determination time interval with respect to the accumulated time of the humidifying operation or the draining operation is set to about 100 hours, for example.
When the humidifier 11 can change the output of the humidifying operation or the draining operation such as the motor rotation speed of the blower 6 and the opening degree of the drain valve 5a, the determination unit 17d determines the time change of the output. Calculate the corrected integration time.

In the humidifier 11, the measuring means 19 includes a detector 19 a that detects the upstream temperature of the air that passes through the humidifying element 2, a detector 19 b that detects the downstream temperature of the air that passes through the humidifying element 2, A detector 19c for detecting a flow rate of air passing through the humidifying element 2, and a measuring means 19 for detecting a temperature and humidity upstream of the air passing through the humidifying element 2 and the humidifying element 2 And a detector for detecting the temperature and humidity on the downstream side of the passing air.

A plurality of measuring means 19 having different methods may be shared.

In the humidifier 11, the determination unit 17 d determines the degree of deterioration based on the actual measurement of the measurement unit 19, but the measurement unit 19 is not provided, and the determination unit 17 d is an area where the humidification device 11 is used. Such information may be obtained through, for example, a communication line, the degree of deterioration is estimated based on the information, and the magnitude of the estimated degree of deterioration may be determined.
When the determination unit 17d determines the degree of deterioration based on the actual measurement of the measurement unit 19, a more appropriate drainage time interval and drainage time are set.

In the humidifier 11, the setting unit 17 a raises the rank to be selected to the side where water consumption increases when the degree of deterioration is large, but the setting unit 17 a depends on how large the degree of deterioration is. You may change the range of the rank.
In addition, when the degree of deterioration is small, the setting unit 17a may lower the rank that is selected to reduce water consumption.

The controller 17 may include the selection unit 7c as in the humidifying device according to Embodiment 1.
In such a case, the controller 17 causes the determination unit 17d to function when, for example, a user, a maintenance worker, or the like does not operate the selection unit 7c.

As mentioned above, although Embodiment 1 and Embodiment 2 were demonstrated, this invention is not limited to description of each embodiment.
For example, it is also possible to combine each embodiment or each modification.
