DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidity controller for dehumidifying, humidifying or ventilating a room.

[0002]

2. Description of the Related Art Conventionally, this type of humidity controller has a configuration as shown in FIG. Hereinafter, the configuration will be described with reference to FIG. In FIG. 8, the humidity controller 1
Inside, two air passages are formed that communicate with the indoor air intake port 2 facing the room and branch from the suction of indoor air to the exhaust air on the downstream side. That is, a moisture absorption air passage 3 for exhausting dry air by absorbing moisture in the indoor air introduced from the indoor intake port 2 on the way.
And a regenerating air path 4 for exhausting the moist air by desorbing moisture absorbed in the hygroscopic air path 3 and mixing with the indoor air sucked from the indoor air inlet 2. I have.

[0005] Reference numeral 5 denotes a moisture absorbing rotor disposed over the moisture absorbing air passage 3 and the regeneration air passage 4, and is an adsorbent for a band-shaped sheet-like base material such as a ceramic sheet having a predetermined width and length. A solution obtained by impregnating a solution in which zeolite was dissolved and supporting the same was bonded to a band-shaped flat sheet impregnated and supported with zeolite and subjected to a corrugating process with a height of about 1 mm to 1.5 mm. Thereafter, it is formed in a substantially cylindrical shape by being wound in the length direction. Therefore, when the moisture-absorbing rotor 5 is viewed from the front, there are many honeycomb-shaped gaps similar to the cross section of the corrugated cardboard, and the pressure loss of the air passing through the moisture-absorbing rotor 5 in the axial direction is reduced. Have been. The moisture absorbing rotor 5 is connected at its center to a rotor rotating motor 6 via a shaft 6a, and rotates around the shaft 6a as the motor 6 is driven.

A moisture absorption fan 7 and a regeneration fan 8 are provided upstream of the moisture absorption rotor 5 in the moisture absorption air passage 3 and the regeneration air passage 4, respectively. Reference numeral 9 denotes an air path switching damper, which can change its direction according to the use of the humidity controller 1. FIG. 12 is a configuration diagram near the air path switching damper 9. As shown in FIG. 12, a substantially cylindrical switching member 10 is fixed to the air path switching damper 9 by bonding or the like, and one end is provided at the center of the air path switching damper 9 and the switching member 10. A shaft 11a connected to the damper rotation motor 11 is inserted therethrough.

The switching member 10 has notches 10a formed at two locations on the side surface thereof.
The portion between 0a and 10a is an arc-shaped convex portion 10b. Reference numeral 12 denotes a microswitch, and ON / OFF control of driving of the damper rotation motor 11 is performed by opening and closing the contact 12a. The state shown in FIG. 11 is a state in which the contact 12a is immersed in the concave portion 10a of the switching member 10 and is opened, and therefore, the microswitch 12 is turned off.

In this state, for example, when a user selects and operates an appropriate operation button (not shown) from an operation panel (not shown) provided on the external part of the humidity controller 1, the motor 1 is operated.
1 drives the air path switching damper 9 and the switching member 10 to rotate in the direction of the arrow A together. Shortly after the rotation starts, the contact 12a of the micro switch 12 comes into contact with the convex portion 10b of the switching member 10 so as to ride thereon, whereby the contact 12a is closed and the micro switch 12 is turned on.

At this time, the rotation of the switching member 10 is continued by the control unit (not shown), and further the rotation proceeds, and when the contact 12a enters the other concave portion 10a, the micro switch 12 is turned off again at that moment. Becomes Even if the microswitch 12 is turned off, the rotation of the air path switching damper 9 does not stop immediately due to the action of inertia.
Since the stopper 13 for positioning (see FIGS. 8 to 11) is provided, unnecessary rotation is prevented, and the air path switching damper 9 can be surely rotated to an appropriate position and stopped. Therefore, in this case, the air path switching damper 9 rotates bidirectionally in a range of about 90 °.

Returning to the description of FIG. Reference numeral 14 denotes an indoor exhaust port provided on the indoor side of the humidity controller 1, and reference numeral 15 denotes an outdoor exhaust port provided facing the outside. A filter 16 is provided on the downstream side of the indoor air intake port 2 to remove dust and the like contained in air introduced from the room.
Further, the moisture absorbing rotor 5 and the regeneration fan 8 inside the regeneration air passage 4
A heater 17 is incorporated between the two.

The operation of the conventional dehumidifier during the dehumidifying operation in the above configuration will be described with reference to FIG. The arrows in the figure indicate the flow of air. In this case, as shown in the drawing, the air path switching damper 9 is configured such that the outlet 31 of the moisture absorbing air path 3 communicates only with the indoor exhaust port 14, while the outlet 41 of the regeneration air path 4 communicates only with the outdoor exhaust port 15. Switch. In this state, the rotor rotation motor 6,
Electric power is supplied to the moisture absorption fan 7, the regeneration fan 8, and the heater 17.

The moisture in the indoor air guided from the indoor air intake port 2 to the hygroscopic air passage 3 by the hygroscopic fan 7 is absorbed by the hygroscopic rotor 5, and the dried air is exhausted from the indoor exhaust port 14. On the other hand, the indoor air flowing into the regeneration air passage 4 by the regeneration fan 8 is heated by the heater 17 and passes through the moisture absorption rotor 5. At this time, moisture is desorbed from the moisture absorbing rotor 5 that has absorbed moisture in the moisture absorbing air passage 3, and humid air containing a large amount of moisture is discharged from the outdoor exhaust port 15. Accordingly, the moisture in the indoor air is gradually removed by the repeated moisture absorption / desorption of the moisture in the moisture absorption rotor 5 and the exhaustion of the dry air into the room and the discharge of the humid air outside the room, thereby providing an appropriate dehumidification effect. can get.

Next, the operation during the humidification operation will be described with reference to FIG. In this case, as shown in the drawing, the air path switching damper 9 communicates with the outlet 31 of the moisture absorbing air path 3 only to the outdoor exhaust port 15, while the outlet 41 of the regeneration air path 4 connects to the indoor exhaust port 14.
Switch to communicate only with In this state,
Power is supplied to the rotor rotation motor 6, the moisture absorption fan 7, the regeneration fan 8 and the heater 17.

The moisture in the room air guided to the moisture absorption passage 3 by the moisture absorption fan 7 is absorbed by the moisture absorption rotor 5, and the dried air is exhausted from the outdoor exhaust port 15. On the other hand, the room air flowing into the regeneration air passage 4 by the regeneration fan 8 passes through the moisture absorption rotor 5 which is heated by the heater 17 and rotates. At this time, moisture is desorbed from the moisture absorbing rotor 5 that has absorbed moisture in the moisture absorbing air passage 3, and humid air containing much moisture is discharged from the indoor exhaust port 14. Therefore, moisture is gradually replenished to the indoor air by the repeated moisture absorption / desorption of moisture in the moisture absorption rotor 5 and the resulting exhaustion of dry air to the outside and exhaustion of the humid air to the interior of the room, thereby obtaining an appropriate humidification effect. Can be

Further, the operation at the time of ventilation will be described with reference to FIG. In this case, the damper 9 is switched to the same position as in the humidification operation, and the moisture absorption fan 7 is energized to operate. At this time, control is performed so that power is not supplied to the rotor rotation motor 6, the reproduction fan 8 and the reproduction heater 17 in the reproduction air path 4. As a result, the indoor air flows in from the indoor intake port 2 by the moisture absorbing fan 7 and is discharged outside from the outdoor exhaust port 15 through the moisture absorbing air passage 3. Therefore, indoor ventilation can be performed.

The state shown in FIG. 11 shows the position of the air passage switching damper 9 when the operation of the humidity controller 1 is stopped. The damper 9 causes the outlet 31 of the moisture absorption air passage 3 and the outlet of the regeneration air passage 4. 41 are both closed. This prevents the inflow of outdoor air into the room and the leakage of indoor air to the outside. The stop of the damper 9 in such a position is performed simultaneously with the stop of the operation of the humidity controller 1 by the damper driving motor 11 (FIG. 11).
Can be performed by turning off the motor 11 after a predetermined time has passed since the micro switch 12 (FIG. 11) was turned on.

[0015]

However, in the structure of the conventional humidity controller 1 described above, the air flow of the moisture absorption fan 7 and the regeneration fan 8 and the heat generation of the heater 17 can be controlled only at predetermined values. In particular, when the humidifying operation is performed in a dry state such as in winter, the moisture cannot be sufficiently absorbed by the moisture absorbing rotor 5 in the initial operation, and it takes a very long time to start up until the humidity reaches a comfortable level. I was Further, the humidity at which the user feels comfortable depends on the indoor temperature, the airtight state, and the like. However, even if these change, there is a problem that appropriate humidification cannot be performed accordingly.

The present invention has been made in view of the above-mentioned conventional problems, and can reduce the time required for raising the indoor humidity during a humidifying operation, and is optimal according to changes in the indoor temperature and airtightness. It is an object of the present invention to provide a humidifier capable of obtaining a humidifying effect.

[0017]

In order to achieve the above object, the present invention provides a moisture absorbing means for adsorbing moisture in the air, and desorbing the moisture absorbed by the moisture absorbing means from the moisture absorbing means by heating. In a humidity controller that includes a heating unit and performs dehumidification, humidification, or ventilation in a room, a control unit that controls a calorific value of the heating unit is provided.

According to this, the amount of heat generated by the heat generating means is controlled by the control unit, so that the humidifying capacity can have a margin.

Further, the present invention provides a moisture absorption air path and a regeneration air path communicating with an indoor air intake port, and a moisture absorption section rotatably disposed across the moisture absorption air path and the regeneration air path to absorb moisture in the moisture absorption air path.

The amount of moisture adsorbed by the moisture absorbing rotor in the moisture absorbing air path and the amount of moisture desorbed from the moisture absorbing rotor by being heated by the heating means in the regeneration air path can be adjusted.

Further, the present invention provides a moisture absorption air passage and a regeneration air passage communicating with an indoor air intake port, and a moisture absorption passage rotatably disposed across the moisture absorption air passage and the regeneration air passage to absorb moisture in the moisture absorption air passage.

The amount and the amount of water desorbed from the moisture absorbing rotor by being heated by the heating means in the regeneration air passage can be adjusted over a wide range.

When humidifying a room by a humidity controller,

[0025]

Embodiments of the present invention will be described with reference to the drawings. In the humidity controller according to the present invention, the same members as those of the conventional humidity controller are denoted by the same reference numerals, and detailed description thereof will be omitted. In addition, the operation and effect of the dehumidifier according to the present invention during dehumidification and ventilation operation are not significantly different from those of the above-described conventional humidity controller. The case of driving will be described.

FIG. 1 is a sectional view of an example of the humidity controller according to the present invention. A characteristic configuration of the humidity controller 1 according to the present invention is that an indoor temperature sensor 18 and an indoor humidity sensor 19 are provided on the downstream side of the opening of the indoor intake port 2 as shown in FIG. These various sensors are all connected to a control unit 22 (see FIG. 4) described later.

When humidifying the air in a dry room, such as in winter, by the humidity controller 1, immediately after the operation is started, the moisture contained in the air is very small. In such an early stage of operation, even if the upper limit of the amount of moisture that can be absorbed by the moisture absorbing rotor 5 is large, if the amount of air generated by the moisture absorbing fan 7 in the moisture absorbing air passage 3 is small, the moisture absorbing ability of the moisture absorbing rotor 5 is reduced. Since the water cannot be sufficiently exerted, the amount of water that can be supplied to the room from the indoor exhaust port 14 through the regeneration air passage 4 by desorbing the water adsorbed on the moisture absorbing rotor 5 by heating by the heater 17 is reduced. Therefore, it may take a long time for a dry room to have a comfortable humidity.

Therefore, as shown by the solid line in FIG. 2, for a predetermined time t from the start of the humidification operation, the moisture absorption fan 7
It is driven at an air flow rate Q2 that is greater than 1 and thereafter a predetermined air flow rate Q
Drive down to 1. As a result, as compared with the case where the moisture absorption fan 7 is operated from the beginning with the air flow Q1 (dotted line in FIG. 2), the relative humidity in the room rises faster, and reaches the desired value in about half the time (T2). Can be done.

On the other hand, when the operation of the moisture absorbing fan 7 at the air flow rate Q2 larger than the predetermined air flow rate Q1 is continued after the elapse of the time t, only when the air flow rate Q2 is larger than the air flow replaced by the natural ventilation of the room, Due to natural ventilation, the rate of dry air entering the room is increased, and the dilution of moisture in the room air is promoted, and the efficiency of humidification is rather deteriorated. That is, as shown by the one-dot chain line in FIG. 2, the value of the relative humidity in the room that finally reaches is low. In this case, power consumption is disadvantageous, and running costs may increase.

Note that the timing of the time t for shifting the amount of moisture absorbed by the moisture absorbing fan 7 from Q2 to Q1 may be set to a predetermined time in advance, or based on the result detected by the indoor humidity sensor 19. Automatic control may be performed.

Next, the operation of the humidity controller 1 after the indoor humidity reaches a stable state will be described. As described above, when the humidification by the humidity controller 1 starts, the humidity in the dry room rises due to the humidification, and reaches a substantially constant value after a lapse of a sufficient time and stabilizes. FIG. 3 is a table showing the relationship between the indoor humidity value and the indoor airtightness that have reached the stable state in this way. As an example, the amount of moisture absorbed by the moisture absorption fan 7 by the humidity controller 1 installed in the room is fixed to 0.5 m ³ / min, and the natural ventilation rate is 0.5 times / h and 0.7 times / hour depending on the airtightness of the room.
h, 1.0 times / h. In a room with a natural ventilation rate of 0.5 times / h, a relatively high humidity of 42.0% can be obtained in a room with a natural ventilation rate of 0.5 times / h.
Humidity drops to 27.6% in a room at 1.0 times / h.
Therefore, a sufficient humidifying effect cannot be obtained unless the amount of moisture absorbed by the moisture absorbing fan 7 is appropriate for the airtight state of the room. In addition, the indoor humidity changes depending not only on the amount of moisture absorbed by the fan 7 but also on the amount of air blown by the regeneration fan 8 in the regeneration air passage 4 and the amount of heat generated by the heater 17.

Therefore, by controlling the operations of the moisture absorbing fan 7, the regenerating fan 8 and the heater 17 in accordance with the indoor temperature and the airtight state, it is possible to realize a suitable humidifying capacity in the room. FIG. 4 is a block diagram showing the configuration of such a control mechanism. As shown in FIG. 4, inside a microcomputer 21 (hereinafter, referred to as “microcomputer”), a control unit 22 that controls the operation of the humidity controller 1, and detection signals from the indoor temperature sensor 18 and the indoor humidity sensor 19. A humidity calculating unit 23 for calculating the absolute humidity in the room based on the above, a humidity comparing unit 24 for comparing the value of the absolute humidity obtained by the humidity calculating unit 23 with a predetermined value, and a moisture absorbing fan in accordance with a command from the control unit 22. 7, heater 17 and regeneration fan 8
There is provided a moisture absorption fan drive circuit 25, a heater drive circuit 26, and a reproduction fan drive circuit 28 for controlling the supply of electricity to the fan.

FIG. 5 is a flowchart of an example of the operation control of the humidity controller configured as described above. When the humidifier 1 starts the humidification operation, the moisture absorption fan 7 and the regeneration fan 8 are driven by the moisture absorption air volume Q and the regeneration air volume W, respectively, and the heater 17 is energized to generate the regeneration air passage 4 (FIG. 1).
The regeneration air flowing through the inside is heated. In step # 10,
The indoor temperature sensor 18 detects the indoor temperature, and the indoor humidity sensor 19 detects the indoor humidity (relative humidity). Then, the result is input to the humidity calculator 23,
The humidity calculating unit 23 calculates the absolute humidity value H (%) at room temperature (step # 20).

The value of H is compared with a predetermined value a by the humidity comparing section 24 (step # 30). If the value of H is less than a, the amount of absorbed air Q is changed (step # 40), and the flow returns to step # 10 to detect the room temperature and humidity again. FIG. 6 shows an example of how the absolute humidity in the room changes when the amount of the absorbed air is variously changed. As shown in FIG. 6, when the operation of the hygroscopic fan 7 is started with the amount of hygroscopic air Q, even if a considerable time has elapsed, the indoor absolute humidity value H is a predetermined value compared by the humidity comparing unit 24. Since it is smaller than a, for example, the moisture absorption air volume is changed to an air volume Q + larger than Q. After a while in this state, the value H of the indoor absolute temperature is obtained again, and this is compared with the predetermined value a.

In this case, since the value of H is rather small, the control unit 22 issues a command to the hygroscopic fan drive circuit 25 to change the hygroscopic air flow Q- to a value smaller than Q in step # 40. In this case, although the absolute humidity in the room tends to increase, the value of H is still smaller than the predetermined value a. Therefore, in step # 40, the hygroscopic fan 7 is operated again at a lower hygroscopic air flow Q--. It controls the moisture absorption fan drive circuit 25. Then, after a lapse of a predetermined time, the value H of the indoor absolute humidity exceeds the predetermined value a for the first time, and this is determined by the humidity comparison unit 24 in step # 30.

Then, the process proceeds to step # 50, where a command is issued from the control unit 22 to the moisture absorption fan drive circuit 25 in order to maintain the operation of the moisture absorption fan 7 at the moisture absorption air amount (in this case, Q--). In this manner, the amount of moisture to be absorbed that satisfies the optimal humidification condition according to the size of the room and the degree of air density (ventilation rate) is determined, and the humidification operation is continued with the amount of air.

However, even if the process from the detection of the absolute humidity in the room to the comparison is repeated, it is not possible to obtain the optimum amount of moisture to be absorbed in the humidifying operation due to the size of the room and the airtightness of the room, ie, step # If the absolute humidity value H in the room does not reach the predetermined value a set in advance at 30, it is considered that the regeneration ability is small with respect to the moisture absorption ability, and it is necessary to increase the regeneration efficiency.

Therefore, as shown in FIG.
The number of loop iterations between 0 and step # 10 is
Counter i reset to zero (step # 5) in advance
Is counted by the control unit 22 by using (Step # 5)
5). When the counter i becomes 3, that is, when the loop is repeated three times, the process proceeds to step # 60, where a command is issued from the control unit 22 to the moisture absorbing fan drive circuit 25,
The moisture absorption fan 7 is operated with the moisture absorption air flow that provides the highest absolute humidity in the room among the variously changed absorption air volumes.
It should be noted that the number of repetitions of the loop need not necessarily be three.

Then, in step # 65, another counter j
Is reset to zero, and in step # 70, the reproduction air volume of the reproduction fan 8 is set to an air volume q +
Next, the controller 22 controls the heater drive circuit 26 and the reproduction fan drive circuit 28 so as to change the heater capacity of the heater 17 to a capacity W + larger than the initial value W, respectively.

In this state, the indoor humidity and temperature are again detected by the indoor humidity sensor 18 and the indoor humidity sensor 19 (step # 80), and the results are used in step # 9.
At 0, the absolute humidity H (%) is calculated by the humidity calculator 23. Then, the value of H is compared with a predetermined value a set in advance by the humidity comparator 24 (step # 100),
If the former is equal to or greater than the latter, the process proceeds to step # 110, where the controller 22 controls the heater driving circuit 26 and the reproducing fan driving circuit 28 to maintain the reproducing air volume and the heater capacity.

On the other hand, if the value of H is smaller than the predetermined value a, the process proceeds to step # 105, and as long as the counter j is smaller than 3, the regeneration air volume is set to q ++ larger than q +, and the heater capacity is set larger than W +. Change to W ++ (step # 120). Then, in step # 125, the counter j is incremented by one, and the process returns to step # 80 and starts again from the detection of the indoor temperature and humidity.

Even if the counter j becomes 3, that is, even if the loop between step # 100 and step # 80 is repeated three times, if the value of H is still smaller than the predetermined value a, step # The process proceeds from step 105 to step # 110, where the control unit 22 outputs to the heater driving circuit 26 and the reproduction fan driving circuit 28 so as to maintain the last-changed reproduction air volume and heater capacity. Then, the process returns to step # 5, and the above-described series of control is continuously repeated. Thereby, a comfortable humidity environment according to the size of the room and the airtight state can be realized. It goes without saying that the loop is not necessarily required to be repeated three times.

[0043]

As described above, according to the present invention, when a room is humidified by a humidifier installed in a dry room in winter or the like, a large amount of water is absorbed by increasing the amount of moisture absorbed for a certain period of time from the start of humidification. Is supplied into the room, so that the time required for raising the humidity from a low indoor humidity can be shortened.

Further, since the temperature and the humidity in the room are detected and the amount of the absorbed air suitable for the size and the airtight state of the room is determined and humidified, an efficient and comfortable humidifying effect can be obtained. Furthermore, since the amount of moisture supplied to the room is controlled by controlling the amount of regeneration air and the amount of heat generated by the heating means, a comfortable humidity environment can be realized without being affected by the size and airtightness of the room.
