Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying / humidifying device for controlling the indoor environment.

[0002]

2. Description of the Related Art Conventionally, this type of indoor environment control device is mainly a product having a single function, and as an indoor environment control device for comprehensively controlling the indoor environment, it is used in a special environment such as a clean room or a hospital. However, the present situation is that the configuration is also performed with a combination of single-function products, and it hardly existed as an indoor environment control device for general households. For this reason, conventionally, a method of maintaining a comfortable indoor environment by combining the products having the above-mentioned individual functions and managing the products according to the usage environment has been adopted.

For example, when dehumidifying a room, a dry operation of an air conditioner or a dehumidifier is used, various humidifiers are used when humidifying, a ventilation fan is used for indoor ventilation, and a room air is circulated. It was done using a circulator and an air purifier. Further, among the above single-function products, there are composite products having about two functions, but they do not exist as indoor environment control devices having all the functions.

[0004]

In the above-mentioned prior art, there is no device that comprehensively controls the indoor environment.
Therefore, it is necessary to combine the single-function products in accordance with the usage environment. If you want to maintain a comfortable indoor environment, you must have all the equipment. Therefore, the initial cost increases and there is a problem in terms of installation. Furthermore, since it is a single product in terms of usability, there is an inconvenience that a person has to operate each time according to the usage environment. For example, in conventional dehumidifiers, the refrigerant type that uses a compressor is the mainstream, and in this case, it takes time and effort to remove the dehumidified water in the room each time, and the humidifier also supplies water for humidification. I had to do the work that I had to do.

The present invention is to solve the above-mentioned problems. By controlling circulation of indoor and outdoor air through an adsorbent containing zeolite as a main component, dehumidification, humidification, ventilation, circulation and a combination operation of the above modes are performed. By performing the above, the indoor environment is controlled by one device, and a convenient dehumidifying / humidifying device is provided.

[0006]

In order to solve the above-mentioned conventional problems, the present invention provides an air supply path and an exhaust path which can be switched between indoor and outdoor by a damper using a stepping motor. Install a blower on the side and install a temperature sensor and a humidity sensor in the air intake part of the blower. Further, a damper for opening adjustment and a heater for heating air are arranged at the outlet of the blower, and an adsorbent containing zeolite as a main component is arranged downstream thereof, and the air supply and exhaust paths of the indoor and outdoor are switched, and heater control is performed. By doing so, the basic functions of desorption of water by the adsorbent and the drainage of water using the adsorption action, dehumidification, humidification, ventilation, and circulation without the trouble of replenishment are obtained. A temperature sensor for switching the path, controlling the heater, and air flow.
It is configured by a control unit that performs information based on the humidity sensor, a display unit that displays a control state, indoor / outdoor temperature and humidity, and an operation unit that instructs switching of the above operations.

Further, the control unit has a basic operation setting unit for setting an operation mode based on an outdoor temperature obtained by switching a path by a temperature sensor provided in an intake unit of the blower, and whether or not the air supply preheating is performed based on the outdoor temperature and the indoor temperature. The preheating control unit that sets the operation mode, the operation mode change unit that changes the operation mode with the output and the set value of the humidity sensor, and the operation instruction unit that sets the operation pattern of each operation mode. It is composed of a humidification operation unit, a dehumidification ventilation operation unit, a humidification ventilation operation unit, a ventilation operation unit, and a circulation operation unit, and outputs a load control signal. In this load control, the stepping motor operation of the path switching damper has a control configuration that does not output at the same operation pattern for the purpose of reducing the operation frequency. Further, there is a load control unit that controls the load with a signal from the operation instruction unit. Further, there is a display setting unit for sending a display signal to the display unit, and this display setting unit converts information obtained by the temperature sensor into indoor temperature and outdoor temperature data and humidity sensor information into humidity data. It is composed of a part and a part for converting the operating state into display data.

In the control unit configured as described above, an operation pattern is automatically selected from each sensor information based on the operation command from the operation unit to control the load, and the operation control according to the indoor environment is performed. This creates a comfortable indoor environment.

[0009]

With the above-described structure, the present invention enables selection of seven types of operation modes including automatic operation and dehumidification, humidification, dehumidification ventilation, humidification ventilation, ventilation, and circulation according to an instruction from the operation unit. In the isolated operation, the load is controlled based on a preset operation pattern to operate, and in the automatic operation, the temperature sensor and the humidity sensor installed in the intake section combine the independent operation modes according to the indoor and outdoor environment conditions to improve efficiency. Control the indoor environment.

In general, the relative humidity is high in the summer and the dehumidifying operation is required. On the contrary, the relative humidity is low in the winter, and the humidifying operation is required due to the use of a heating appliance. In the automatic operation, the temperature sensor installed in the intake section distinguishes between summer and winter to detect the outdoor temperature.If it is below the set temperature, it is judged as winter, and if it is above the set temperature, it is judged as summer. The humidification operation and the dehumidification operation in the summer are mainly set, and thereafter, the control is performed by the operation set by the operation mode changing unit by the output of the humidity sensor.

The operation pattern of each operation mode is set by setting the combination of air supply and exhaust paths, heater heating control, blower rotation speed control, and blower outlet damper control.

For example, in the case of dehumidifying operation, first, the air supply path is set to the indoor side, and the exhaust path is also set to the indoor side.
The fan is rotated for a predetermined period of time with the blower rotation speed Hi in the heater OFF state and the damper "open". That is, the indoor air is circulated through the adsorbent, the moisture in the air is adsorbed by the adsorbent, and the dry air is discharged into the room. This operation is called a suction operation. Since the adsorption of water on the adsorbent is saturated after a lapse of a predetermined time, the air supply path and the exhaust path are set to the outside of the room, the rotation speed is switched to low speed with the heater turned on, and the damper is set to the "closed" state. Is reduced to operate for a predetermined time. As a result, the temperature of the adsorbent rises, the moisture adsorbed on the adsorbent is desorbed, and the moisture is discharged to the outside as humid air. This operation is called detachment operation. After a lapse of a predetermined time, the adsorbent is ready to adsorb moisture again, and thus the desorption operation is performed. By repeating the desorption operation and the adsorption operation in this manner, moisture in the room air is discharged to the outside of the room to perform the dehumidification operation of the room.

In the humidifying operation, the air supply path and the exhaust path in the desorption operation and the adsorption operation are opposite to those in the dehumidification operation. The detailed operation will be described in the section of the description of the embodiment including the description of other operation modes.

As described above, since the dehumidifying and humidifying operations are performed by switching the blowing path, controlling the heater and controlling the blowing amount using the adsorbent, it is not necessary to discharge the water generated during the dehumidifying operation, and the water supply during humidification is performed. Therefore, a maintenance-free dehumidifying / humidifying device can be provided.

Further, a combination of dehumidification, humidification, ventilation, circulation and preheating can be automatically controlled by a temperature sensor and a humidity sensor provided in the intake section, so that optimum indoor environment control can be realized.

In the above structure, the basic operation will be briefly described. First, the dehumidifying operation is set in the indoor air supply 1 and the indoor exhaust air 15 by switching the air blowing path. In this state, the blower 8 is operated for a predetermined time to circulate the room air through the adsorbent 13. That is, the moisture in the room air is adsorbed by the adsorbent 13 and the dry air is released into the room. After a lapse of a predetermined time when the adsorption on the adsorbent 13 is saturated, the ventilation path is switched between the outdoor air supply 18 and the outdoor air exhaust 17. Next, the air blower 8 is operated for a predetermined time while the heater 11 is heated, and the water adsorbed on the adsorbent 13 is desorbed and discharged outside the room. When a predetermined time has passed, the suction operation is performed again. Thus, the indoor dehumidification is performed by repeating the operations of indoor adsorption and outdoor desorption. As described above, in the dehumidifying operation, the water in the room is automatically discharged to the outside through the adsorbent, so that it is not necessary for a person to discharge the water accumulated by the dehumidification.

The humidifying operation is the opposite operation to the dehumidifying operation to discharge the moisture outside the room to humidify the room.
That is, the air blower 8 is driven for a predetermined time by the outdoor air supply 18 and the outdoor exhaust air 17 in the air blowing path to cause the adsorbent 13 to adsorb the outdoor moisture. Next, the ventilation path is set to indoor air supply 1 and indoor exhaust air 15
And the blower 8 is operated for a predetermined time while the heater 11 is heated. As a result, the water content of the adsorbent 13 is desorbed and released into the room. Humidification is performed by repeating the above operation. In the case of the humidifying operation, since the outdoor moisture is used to humidify, the labor of water supply can be saved.

The dehumidification / ventilation operation is an operation in which indoor air is exhausted and fresh outdoor air is introduced, and the dehumidification operation is added to the ventilation operation. The air is dried by the adsorbent 13 and taken into the room. At the time of desorption, the air supply path is the indoor air supply 1,

The outdoor exhaust 17 is used to discharge dirty air in the room. At the same time, the moisture is adsorbed to the adsorbent 13, and the ventilation path is switched by the desorption operation to take in the outdoor air, and at the same time, the moisture of the adsorbent 13 is released into the room for humidification.

The ventilation operation is configured to perform four operations of forced air supply, forced exhaust, supply / discharge automatic ventilation, and preheat ventilation, and the ventilation mode is switched by switching the air blowing path in the non-energized state of the heater. . The supply / exhaust automatic ventilation and the preheating ventilation are selected by the signal of the supply air temperature sensor 6.

Similarly, the circulation operation also functions as a circulator by operating the blower 8 in the ventilation path of the indoor air supply 1 and the indoor exhaust air 15 with the heater de-energized.

As described above, six operating modes are created by the combination of the ventilation paths to control the indoor environment.

Next, a specific control configuration for performing the above operation will be described with reference to FIG.

Reference numeral 24 denotes a preheat control unit that estimates the dew point temperature from the indoor temperature and the outdoor temperature obtained by the air supply temperature sensor 6 and performs preheat control during air supply to prevent dew condensation. A safety circuit 25 outputs an operation stop signal in response to a signal from the temperature sensor 14 at the blowing portion.

Reference numeral 26 is an operation instructing section, which is a section in which load operation patterns are set for the above-mentioned six operation modes, and is composed of the following six elements. 26A is a dehumidification operation part, 26B is a humidification operation part, 26C is a dehumidification ventilation operation part,
26D is a humidification ventilation operation part, 26E is a ventilation operation part, 26F
Is a part in which the operation pattern of the load at each operation is set in the circulation operation part. Reference numeral 27 denotes a portion for instructing an operation mode on the operation unit.

Display on 2 The operation mode display 32 is also composed of ten display units 32A to 32J corresponding to each operation mode. A load control unit 33 supplies a signal to the drive circuit of each load according to the signal from the operation instructing unit 26.

The operation of the control unit in the above configuration will be described with reference to the flow charts of FIGS. First, the operation mode is selected by the operation instructing unit, and the operation is started by supplying a signal to the operation instructing unit 26 via the operation unit 27. Since the automatic operation 27A is composed of a combination of individual operations, a detailed description of each individual operation will be given using a flowchart.

The humidifying operation will be described with reference to FIG. 7. When the humidifying operation instruction 27B is selected, a signal is supplied to the humidifying operation section 26B of the operation instructing section 26 via the operation section 27. When the signal is supplied, the stepping motor 16 is operated to set the air supply path to the indoor side, and the stepping motor 19 is operated to set the exhaust path to the indoor side. Further, the stepping motor 9 is operated to bring the damper 9A into the "closed" state, and the blower 8 is operated at "weak". At the same time, the heater 11 is turned on to perform the desorption operation of the adsorbent 13. When the predetermined time td has elapsed, the heater 11 is turned off and the supply temperature, that is, the room temperature is checked. This is for correcting the time of the desorption purge operation performed to improve the efficiency of the desorption operation based on the indoor temperature, and the desorption purge time td 'is set according to the checked indoor temperature.

When this desorption purge time has elapsed, the air blowing path is switched to the outdoor air supply 18 and the outdoor air exhaust 17, the air volume adjusting plate 9A is set to the "open" state, and the blower 8 is operated at "strong". This operation is performed for a preset adsorption time ta to adsorb the outdoor moisture to the adsorbent 13. When the adsorption time ta elapses, the blower 8 is changed to "weak" operation, and when a predetermined time elapses, the ventilation path is switched to the indoor air supply 1 and the indoor exhaust air 15 again, and the desorption operation described above is performed to adsorb to the adsorbent 13. The humidified water is discharged by discharging it into the room. Further, in the above operation, the change to the “weak” operation of the blower 8 after the adsorption time ta elapses is an operation to reduce the resistance to the damper at the time of switching the ventilation path and to eliminate the wind noise at the time of switching the damper. is there. After that, the above operation is repeated to take the outdoor moisture into the outdoor, so that the maintenance-free humidifying operation can be performed.

Next, the dehumidifying operation will be similarly described with reference to FIG. 6. When the dehumidifying operation instruction 27C is selected, a signal is supplied to the dehumidifying operating portion 26A of the operation instructing portion 26 via the operating portion 27. When the signal is supplied, the stepping motors 16 and 19 are operated to set the ventilation path to the outdoor air supply 18 and the indoor exhaust 17, and the stepping motor 9 is operated to bring the air volume adjusting plate 9A into the "closed" state. In this state, the blower 8 is operated at "weak", and at the same time, the heater 11 is turned on to operate for a predetermined time td. When the desorption time td has elapsed, the heater is turned off to check the supply air temperature, that is, the outdoor temperature, and the desorption purge time is set according to the condition of the outdoor temperature.

By the above operation, the adsorbed water content of the adsorbent 13 at the initial stage is desorbed to improve the efficiency of the adsorption operation. Desorption purge time t
When d ′ passes, the air supply path is changed to indoor air supply 1 and indoor air exhaust 1
5, the air volume adjusting plate 9A is opened and the blower 8 is operated at "strong". As a result, the moisture in the room can be absorbed by the adsorbent 1.
3 is adsorbed on, and dry air is discharged indoors to dehumidify. When the adsorption time ta elapses, the blower 8 is changed to "weak" operation, and after a predetermined time elapses, the desorption operation described above is performed. Or later,
By repeating the above operation, indoor humidity is discharged to the outside of the room to supply dry air, and maintenance-free dehumidifying operation is performed.

The humidification / ventilation operation is shown in the operation flowchart of FIG. 9. Since the basic operation is almost the same as the humidification operation described in FIG. 7, different parts will be briefly described. When the humidifying / ventilating operation 26D is instructed by the humidifying / ventilating operation instruction 27D, the ventilation path is set to the outdoor air supply 1
8. Set to indoor exhaust 15 and perform desorption operation while taking in fresh outdoor air. When the desorption operation is completed in a predetermined sequence, the ventilation path is switched to the indoor air supply 1 and the outdoor exhaust air 17, and the adsorption operation is performed while discharging the dirty air in the room to the outside. As mentioned above, while supplying and exhausting ventilation indoors and outdoors,
The desorption and adsorption operations are performed to perform the humidification operation.

The dehumidifying / ventilating operation is shown in the operation flowchart of FIG. 8, but the basic operation is almost the same as the dehumidifying operation described in FIG. When the dehumidification / ventilation operation instruction 27E is instructed to perform the dehumidification / ventilation operation 26C, a predetermined desorption operation is performed using the air supply path as the indoor air supply 1 and the outdoor exhaust air 18. That is, the desorbing operation of the adsorbent 13 is performed when the dirty air in the room is discharged to the outside, and conversely, the dehumidifying operation is performed while the outdoor air is taken in and the ventilation operation is performed during the adsorbing operation.

As described above, in the dehumidifying / humidifying operation combined with the ventilation operation, compared with the case of performing the dehumidifying / humidifying operation only, there is an advantage in that it is possible to ventilate the room though the performance is slightly lowered.

Next, the ventilation operation will be described with reference to FIGS. The ventilation operation of the dehumidifying / humidifying device of the present invention is configured to have four ventilation modes of forced exhaust, forced air supply, supply / discharge automatic ventilation, and preheat ventilation.
In response to this instruction, the setting can be performed in the forward order as shown in FIG. For forced exhaust operation, the air supply path is indoor air supply 1,
It is set to the outdoor exhaust 17 and the blower 8 is operated at "strong" to discharge the dirty air in the room to the outside.

Next, for forced air supply, the air supply path is set to the outdoor air supply 1
8. With the indoor exhaust 15, the blower 8 is operated at “strong” to introduce fresh air outside the room.

In the automatic ventilation operation, first, the outdoor air supply 18 and the outdoor air exhaust 17 are set in the ventilation path, the blower 8 is operated, and the outdoor temperature is checked. When the outdoor temperature is equal to or higher than the specified value (10 ° C), the supply / discharge automatic ventilation operation is performed, and when the outdoor temperature is equal to or lower than the specified value (10 ° C), the preheat ventilation operation is performed.

The preheating ventilation operation will be described with reference to FIG. 11. First, the blower path is set to the outdoor air supply 18 and the indoor exhaust air 15, and the blower 8 is operated. At this time, the blowout temperature is checked by the temperature sensor 14, and when the temperature is below a predetermined temperature, the heater is energized for a predetermined time to perform the air supply operation. Further, when the blowout temperature becomes equal to or higher than the predetermined value during the air supply operation, the energization of the heater is stopped at that point and the air supply operation is continued. When the air supply operation for a predetermined time is completed, the air supply path is switched to the indoor air supply 1 and the outdoor air exhaust 17, and the air blower 8 is operated at "strong" to perform the air exhaust operation. After that, the above operation is repeated to ventilate the outdoor fresh air at a predetermined temperature, thereby performing a comfortable ventilation operation without lowering the indoor temperature.

Next, when the outdoor temperature checked above is equal to or higher than the specified temperature (10 ° C.), the supply / discharge automatic ventilation operation is performed, and its operation flowchart is shown in FIG. The operation is exactly the same as the preheat ventilation operation without heater heating,
Ventilation is performed by alternately repeating the air supply operation and the exhaust operation at a predetermined cycle.

The circulation operation 26F is performed according to the circulation operation instruction 27G, and as shown in FIG.
The indoor air is circulated in the blower route 5 and combined with the air cleaning operation instruction 27H.
It is used in parallel operation with. FIG. 14 shows an operation flowchart. Further, the air cleaning operation instruction 27H can be combined with other operation modes.

Next, an automatic operation for automatically controlling the indoor environment by combining the above-described individual operations will be described with reference to FIGS. The operation in the operation mode described below is the same as that described above, and thus detailed description thereof is omitted.

First, when the automatic operation instruction 27A is selected, a signal is supplied to the operation instruction section 26 via the operation section 27, and the ventilation path is set to the outdoor air supply 18 and the outdoor exhaust air 17 to check the outdoor temperature. I do. When the outdoor temperature is checked, it is compared with a preset temperature 21, and the result is sent to the basic operation setting section 22 to determine whether it is winter or summer. If it is judged that the outdoor temperature is below the set temperature in winter,
The main control is the humidifying operation, and its detailed operation will be described with reference to FIGS. 3 and 4.

When the basic operation is set in the above operation, the ventilation path is set to the indoor air supply 1 and the indoor exhaust air 15, and the indoor humidity is checked. When the indoor humidity is equal to or higher than the specified value (60%), the automatic ventilation operation is started, and when the indoor humidity is equal to or lower than the specified value (50%), the automatic ventilation operation is stopped and the automatic operation is returned to the initial state. Once the ventilation operation is started, the automatic ventilation operation is continued until the indoor humidity becomes 50% or less. The outdoor temperature is checked during the air supply operation of this automatic ventilation operation, and if this outdoor temperature is below the set value, it is switched to the preheat ventilation operation. This is an operation for taking in cold outside air and preventing condensation. As described above, when the initial indoor humidity is 60% or more in winter, ventilation is performed to replace the indoor dry air with the indoor humidity to bring the indoor humidity into an appropriate state.

Next, when the initial room humidity is 60% to 40%, the humidity is appropriate, so that nothing is done and the system stands by. When the indoor humidity falls below 40%, humidification operation starts and the indoor humidity becomes 5
Continue until 0% or more. When the indoor humidity exceeds 50%, the humidifying operation is stopped and the initial state is restored. Further, when the indoor humidity continues to be between 40% and 50% for a predetermined time or longer, the humidification operation is switched to the humidification ventilation operation to continue the operation, and when the indoor humidity maintains the above state thereafter, the humidification operation and the humidification ventilation are performed. The operation is repeated at a predetermined cycle. In this way, the indoor humidity in winter is controlled within the range of 60% to 40%.

Next, when the initial check of the automatic operation determines that it is summer, the indoor humidity is controlled mainly by the dehumidifying operation as shown in FIG. Similarly to the above, first, the indoor humidity is checked, and if the indoor humidity is 60% or less, nothing is done and a standby state is set. When the indoor humidity is 60% or more, the dehumidifying operation is started, and the operation is continued until the indoor humidity becomes 50% or less. Further, when the room humidity is kept between 60% and 50% for a predetermined time or longer, the dehumidifying operation is switched to the dehumidifying ventilation operation. After that, by repeating the dehumidification and dehumidification / ventilation operations at a predetermined cycle, the indoor humidity is adjusted to 60% in summer.
Control is performed in the range of 50% to 50%.

As described above, the indoor environment control mainly for dehumidification / humidification is realized by controlling the switching of the air flow path and desorbing and adsorbing the adsorbent containing zeolite as the main component, and the temperature sensor provided in the air supply section is realized.
