TECHNICAL FIELD OF THE INVENTION
The present invention relates to a humidifying device that automatically performs appropriate humidifying amount control according to temperature and humidity.
[0002]
[Prior art]
In recent years, as a humidifier, a natural vaporization method that does not use a heating element has become a main product in terms of energy saving. This vaporizing humidifier controls the amount of humidification by adjusting the amount of water of a pump that sends water to a humidification filter and the amount of air blown by a blowing means (fan).
[0003]
Generally, the amount of water of the pump and the amount of air blown by the blowing means are adjusted based on the temperature and humidity in the room. For example, Patent Literature 1 describes detecting the air temperature and the air temperature near the surface of the water absorber, and determining the amount to be sent to the water absorber from the relationship between the temperature difference and the comfortable humidity.
[0004]
Further, in Patent Document 2, when the humidity detecting unit detects that the humidity is uncomfortable, the filter rotation speed is reduced to improve the filter dryness, and thereby the humidity is reduced, resulting in a cool sensation. Is maintained.
[0005]
Patent Document 3 further includes a microcomputer having a humidity sensor, a room temperature sensor, a humidity setting unit, a timer setting unit, a humidification amount control unit, a water vapor generation unit, a timer unit, and a display control unit. The microcomputer automatically selects the humidification amount based on the detection signal from the humidity sensor and the set humidity set by the humidity setting unit, and sets the maximum humidification amount of the selected humidification amount to the time set by the timer setting unit. A control device for a humidifier that automatically corrects based on the control of the amount of steam generated by the steam generator is described.

[Problems to be solved by the invention]
As described above, the conventional humidifier detects the indoor humidity and controls the humidification amount based on a difference from a preset humidity. Specifically, in the evaporative humidifier, the heater that uses the heater is not used as much as possible, and the water contained in the humidifying filter is naturally vaporized. The humidification amount was controlled by driving only the minimum blowing amount.
[0008]
However, in the above control, even if the operation of the pump is stopped, the humidification filter is in a water-containing state, so that by driving the blowing fan, the water remaining in the humidification filter is vaporized and humidified to a high humidity. Air is released outside the device.
[0009]
At this time, since the blowing amount of the blowing fan is minimized, the humidified air stays around the humidifying device. When the humidity sensor detects the humidity of the humidified air, there is a problem that a so-called short circuit state occurs in which the detected humidity is displayed higher than the actual indoor humidity.
[0010]
The present invention has been made in order to solve the above-described problems, and has an object to obtain a humidifying device that can perform a proper humidification control by eliminating a short circuit state when the circuit enters a short circuit state. And
[0011]
[Means for Solving the Problems]
In order to achieve the above object, a humidifying device according to the present invention includes a humidifying unit for humidifying air, a blowing unit for blowing air humidified by the humidifying unit, a humidity sensor for detecting humidity of a space to be humidified, and a humidity sensor. A control device that controls a blowing amount of a blowing unit in order to correct a difference between a detected humidity detected by the sensor and a humidity of an actual humidification target space (hereinafter, abbreviated as an actual humidity). And
[0012]
Here, as a humidifying device, any device of a heating type, an ultrasonic type or a vaporization type can be used. As the humidifying means, a heater is used in the case of the heating type, an ultrasonic generator is used in the case of the ultrasonic type, and a filter is used in the case of the vaporizing type. In the case of a vaporization type, a water supply means for supplying water to the filter may be used, or water may be sucked up to the filter by utilizing a capillary phenomenon.
[0013]
According to the above configuration, when a short circuit state occurs in which a difference between the detected humidity detected by the humidity sensor and the actual humidity occurs, the difference can be corrected by controlling the amount of air blow, Appropriate humidification control can be performed.
[0014]
As a specific control of the blowing amount, when a difference occurs between the detected humidity detected by the humidity sensor and the actual humidity, the operation of the blowing unit may be stopped, or conversely, the blowing may be stopped. It is also possible to increase the air volume.
[0015]
In the former method, the short circuit state can be eliminated by cutting off the release of the humidified air, and in the latter method, the short circuit state can be eliminated by blowing out the humidified air remaining around the humidifier. Can be.
[0016]
Among various types of humidifiers, in the case of a vaporization type humidifier, as described above, the humidification amount is controlled mainly by adjusting the air volume of the air blowing means, and a short circuit state may occur. Is high.
[0017]
Therefore, in the present invention, a blowing means for blowing air through a humidifying filter, a water sending means for feeding water to the humidifying filter, a humidity sensor for detecting humidity, and a difference between a detected humidity detected by the humidity sensor and a preset set humidity. With the control device for controlling the operation of the blowing means and water supply means, when the detected humidity reaches the set humidity, the control device stops the operation of the water supply means and operates only the blowing means, When the detected humidity becomes higher than the set humidity by a certain value or more, it is possible to adopt a configuration in which the operation of the blower is stopped.
[0018]
That is, in the conventional vaporizing humidifier, data for determining the humidification amount (water supply amount, air supply amount) corresponding to the difference between the detected humidity and the set humidity is stored in the control device in advance, and the humidification amount data Based on the operation (hereinafter referred to as normal operation) was performed.
[0019]
Then, when the detected humidity reaches the set humidity, the humidification amount is controlled to the minimum level, that is, by stopping the water supply unit and minimizing the air supply amount of the air supply unit, the humidity is kept below the set humidity. Was configured.
[0020]
Therefore, in the conventional evaporative humidification device, it is not assumed that the humidification amount is controlled to the minimum level and the detected humidity is still higher than the set humidity. This has led to a situation in which humidification control cannot be performed.
[0021]
The present invention has been made in view of the above problem, and in a vaporizing humidifier, when a detected humidity reaches a set humidity, a control device stops operation of a water supply unit and minimizes only a blower unit. The operation is performed with the air flow rate.After that, when the detected humidity becomes higher than the set humidity by a certain value or more, it is determined that the circuit is in the short circuit state, and the normal operation is shifted to the abnormality clearing operation to eliminate the short circuit state. Thus, the operation of the blowing means is stopped.
[0022]
According to the above configuration, by stopping the operation of the blower, the supply of the humidified air that is the source of the short circuit state is cut off, and the humidified air remaining around the humidifier can be eliminated by diffusion. As a result, the detected humidity can be made closer to the actual humidity, and appropriate humidification control can be performed.
[0023]
When the operation of the blower is stopped, the difference between the detected humidity and the actual humidity gradually decreases, but the actual humidity also decreases. Therefore, when the detected humidity falls below the set humidity or drops below a certain value below the set humidity, it is determined that the short circuit state has been resolved, and the operation returns to the normal operation and the operation of the water supply means and the air supply means is resumed. do it.
[0024]
Further, when the operation shifts to the abnormality elimination operation, it may be possible to wait for the detected humidity to return to the humidity with the air blowing means stopped, but if the air blowing means is operated intermittently, it is possible to prevent the short circuit state from being caused. Thus, it is possible to detect the humidity in the humidification target space accurately at an early stage.
[0025]
In other words, by operating the air blowing means, the external air is positively taken in while the humidified air remaining in the device is quickly discharged to the outside, so that the actual humidity can be detected early.
[0026]
In addition, by intermittently operating the air blowing means, even if humidified air starts to stay around the humidifier, the operation is stopped before the humidified air reaches the humidity sensor, and the humidified air that has accumulated during that time can be diffused. By repeating this, it is possible to humidify while preventing a short circuit state from occurring.
[0027]
Immediately after the operation of the blower is stopped, the humidified air still remains around the humidifier, so if the blower is restarted immediately, it will be in the short circuit state again to detect the actual humidity. It may be delayed. Therefore, it is preferable to start the intermittent operation of the blowing means after a lapse of time sufficient for the accumulated humidified air to diffuse.
[0028]
When the detected humidity reaches the set humidity, the water supply means stops operation.If the operation of the air supply means is continued, the humidification filter is dried and the air is no longer humidified, and the humidity of the humidification target space decreases. .
[0029]
Therefore, when the detected humidity is equal to or lower than the set humidity or lower than a set value, the operation of the water supply unit is restarted, the intermittent operation of the air supply unit is terminated, and the air supply unit is continuously operated. Humidification during driving may be performed.
[0030]
In addition, if the operation of the water supply means is restarted together with the intermittent operation of the air supply means after the operation of the water supply means is stopped, a stable humidification operation can be performed for a long time. Even in this case, when the detected humidity falls below the set humidity by a certain value or less due to ventilation or the like, the intermittent operation of the air blowing means may be terminated, and humidification in the normal operation may be performed.
[0031]
Further, when the detected humidity approaches the set humidity, the control device stops the operation of the water supply means and operates by minimizing the amount of air blown by the blow means, and furthermore, the detected humidity rises and is more constant than the set humidity. It is also possible to adopt a configuration in which, when the value becomes higher than the value, the operation is performed by increasing the amount of air blown by the blowing means.
[0032]
That is, when it is determined that the detected humidity increases and becomes higher than the set humidity by a certain value or more and the circuit is in the short circuit state, instead of stopping the operation of the blower as the abnormality elimination operation, the amount of air blown by the blower is reversed. , The humidified air staying around the humidifier is blown away, and the actual humidification can be detected early and appropriate humidification control can be performed.
[0033]
In this case, the amount of humidified air released from the humidifying device also increases by increasing the amount of air blown by the blowing means, but since the supply of water to the humidifying filter is stopped, the amount of water discharged to the outside is reduced. Is only the water remaining in the humidification filter, has little effect on the humidity of the space to be humidified, and there is no possibility that the humidification will be excessive enough to cause discomfort.
[0034]
In this case, when the moisture remaining in the humidifying filter is consumed by the abnormality elimination operation, the detected humidity is reduced. Therefore, when the detected humidity is equal to or less than the set humidity, or when the detected humidity is reduced to a certain value or less than the set humidity. In this case, it is only necessary to return to normal operation and perform humidification control according to the difference between the detected humidity and the set humidity.
[0035]

[0047]
FIG. 3 is a control block diagram of the humidifier. As shown in the figure, the control device 55 is composed of a microcomputer, and includes a control unit 57, a switch input circuit 56, an ion generator driving circuit 58, a blower driving circuit 59, a water pump driving circuit 60, a heating element driving circuit. 61, a switching damper driving circuit 62, on the input side of which is provided a group of operation switches 50 connected to a switch input circuit 56, and a humidity sensor 63 for indoor humidity detection electrically connected to a control unit 57. Are provided.
[0048]
On the output side of the controller 55, the ion generator 18, the blower 19, the water pump 16, the heating body 20, and the switching damper 23, which are driven by the respective drive circuits 58 to 62, are controlled.
[0049]
The operation switch group 50 includes an operation switch 51 for turning on and off the operation, a humidification switch 52, an ion operation switch 53, a humidification setting switch 54, and the like.
[0050]
When the humidification switch 52 is sequentially pushed, an operation mode of “automatic” → “strong” → “medium” → “weak” → “automatic” can be selected. When the humidification setting switch 54 is pressed, the order is “Nodoroi” → “Good night” → “Continuous” → “60% setting” → “50% setting” → “40% setting” → “Nodoroi” The humidity setting switches.
[0051]
Next, the operation of the above humidifier will be described. When the operation switch 51 is set to “ON” and the humidification switch 52 is pressed to select the automatic operation mode, the humidification automatic operation starts. In the automatic humidification operation, the ion generator 18 also automatically performs the combined operation.
[0052]
The humidification operation is performed according to the difference between the detected humidity detected by the humidity sensor 63 and the humidity set by the humidity setting switch 54, or according to the difference between the humidity set in advance and stored. And the rotation of the blower 19 is controlled, so that the humidification amount is changed and the humidification is automatically controlled.
[0053]
For example, when the difference between the set humidity and the detected humidity is large, the amount of water from the humidification filter 14 is increased by increasing the amount of water supplied by the water pump 16 and further increasing the number of rotations of the blower 19 to increase the amount of air blown. The humidification operation for increasing the evaporation amount is controlled.
[0054]
In particular, during the strong humidification operation, or when the difference between the set humidity and the detected humidity is large, the heating element 20 is driven to heat the air sucked into the humidifier, thereby evaporating water from the humidification filter. Control of the humidifying operation is performed to increase the number.
[0055]
When the ion generator 18 is unnecessary during the humidification operation, the drive can be stopped by selecting "OFF" of the ion operation switch, and the humidification operation alone can be used. In this case, the switching damper 23 is switched to a path that passes through the humidifying filter 14 and reaches the outlet 24.
[0056]
FIG. 4 is a flowchart of an execution program during the humidification operation according to the present embodiment. In the figure, “♯” represents each step, and is hereinafter referred to as “step ○”. The present embodiment is characterized in that the operation of the water pump 16 and the blower 19 is stopped as the abnormality elimination operation when the control device 55 determines that the state is the short circuit state.
[0057]
First, in step 200, the operation switch 51 is pressed to turn on, and in step 210, the humidification switch 52 and the humidity setting switch 54 are pressed to select the operation mode and the set humidity, and the operation (normal operation) of the water pump 16 and the blower 19 starts. Is done.
[0058]
At step 220, the set humidity desired by the user is read. Then, the humidity in the room is detected by the humidity sensor 63, the difference between the detected humidity and the set humidity is calculated, and based on a plurality of humidification amount determination data stored in the memory of the control device 55 in advance, the magnitude of the difference is calculated. Humidification control is performed by selecting a humidification amount from data corresponding to the humidification.
[0059]
Next, the process proceeds to step 230, where the detected humidity and the set humidity are compared to determine whether the detected humidity is equal to or higher than the set humidity. If No, the process proceeds to step 220. If Yes, the process proceeds to step 240, in which the water pump 16 (water supply means) is stopped, the blower 19 (air supply means) is operated at a minimum, and the humidification operation is controlled so as to reach the set humidity.
[0060]
By performing such control, the moisture remaining in the humidifying filter 14 is evaporated by the blower 19, and when the blown air volume of the blower 19 is small, humidified air stays around the humidifier.
[0061]
Proceeding to step 250, the detected humidity is compared with the set humidity. If the detected humidity is higher than the set humidity by 2.5% or more, that is, the difference between the detected humidity and the set humidity is {2.5% or more}. Is determined, and in the case of No, the process proceeds to step 230. Here, if the detected humidity is equal to or higher than the set humidity, the water pump 16 is stopped, and the amount of air blown by the blower 19 is kept at a minimum. Humidification operation control is performed according to the difference.
[0062]
If Yes, it is determined that the circuit is in the short circuit state, and the process proceeds to step 260, where the normal operation in which the blower 19 is continuously operated is shifted to the abnormality clearing operation, both the water pump 16 and the blower 19 are stopped, and only the ion generator 18 is driven Then, the humidification operation is controlled so as to reach the set humidity.
[0063]
That is, when the value of the detected humidity becomes 2.5% or more higher than the set humidity, the humidifier is determined to be in the short circuit state, and the control device 55 stops the operation of the water supply pump 16 and the blower 19. The short circuit can be eliminated by diffusing the humidified air staying around the humidifying device.
[0064]
The controller 55 continues to detect the indoor humidity by the humidity sensor even after stopping the operation of the water pump 16 and the blower 19, and determines whether the detected humidity is equal to or lower than the set humidity (Step 270). Detects the humidity again, and in the case of Yes, proceeds to step 280 to return to the normal operation, restarts the operation of the water supply pump 16, ends the intermittent operation of the blowing means, and performs humidification in the continuous operation.
[0065]
In the present embodiment, in step 270, it is determined whether the detected humidity is equal to or lower than the set humidity. However, the operation may return to the normal operation when the detected humidity becomes equal to or lower than the set humidity.
[0066]

The other configuration is the same as that of the first embodiment.
[0067]
That is, in the present embodiment, as shown in FIG. 5, the same humidification control as in steps 200 to 250 in the first embodiment is performed in steps 300 to 350, but in step 360, the water pump 16 In addition, the operation of the blower 19 is stopped, and after a lapse of a predetermined time, the intermittent operation of the blower 19 is started with the minimum blown air amount.
[0068]
With the above control, the room air is actively taken in while the humidified air remaining in the device is quickly discharged to the outside, so that the short circuit state can be eliminated, and the actual indoor humidity can be detected early. Can be.
[0069]
In the present embodiment, the water supply pump 16 is stopped at the time of the abnormality clearing operation. However, the present invention is not limited to this, and the water supply pump 16 may be operated. In this case, stable humidification operation can be performed for a long time. When the blower 19 is operated intermittently, the amount of air blow may be increased.
[0070]

FIG. 6 is a flowchart of an execution program during a humidifying operation according to the third embodiment. The present embodiment is characterized in that, when the control device 55 determines that the state is the short circuit state, the operation of the blower 19 is not stopped, but the amount of blown air is increased. Are the same as in the first embodiment.
[0071]
That is, as shown in FIG. 6, in the present embodiment, the same humidification control as in Steps 200 to 250 in the first embodiment is performed in Steps 400 to 450, but in Step 460, the water supply pump 16 Is stopped, and the blower 19 is operated while increasing the amount of air blown.
[0072]
