Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating and dehumidifying device for ventilating and dehumidifying a space under a floor of a building or the like in combination with spraying of an agent such as an antibacterial agent.

[0002]

2. Description of the Related Art As is typical of Japanese dwellings, in the case of a high-floor type house, a highly durable wooden house can be provided under the floor of the house. In recent years,
Since the underfloor is surrounded by a cloth foundation, there is a slight ventilation hole, but the ventilation under the floor is poor. For this reason, the underfloor has high humidity, mold and rot fungi easily propagate, and the wood constituting the underfloor is easily corroded.

For these reasons, in recent years, the use of underfloor ventilation fans having the structure shown in FIG. 7 has been increasing in order to improve the ventilation under the floor. Reference numeral 1 denotes a blower provided inside the ventilation fan main body 2, which sucks in stagnant air below the floor 9 from an intake port 3 and exhausts it from an exhaust port 4. This ventilation fan body 2
It is provided using a part of ventilation holes 10 provided at several places between the foundation 6 of the building and the base 7 of the building on the north side of the building or under the floor around the water such as a washroom, a bathroom, a kitchen, or the like. . FIG.
Indicates the electrical connection of the underfloor ventilation fan. The controller 11 includes a plurality of ventilation fan main bodies 2a, 2b, 2
c to control the operation.

With the above structure, the controller 11 operates the ventilation fan main body 2 for a predetermined time, generally from about 10 am to about 4 pm when the temperature of the outside air rises and the humidity decreases.
To drive. When the ventilation fan main body 2 operates, as shown by the arrow a, low-humidity air on the south side flows in from the ventilation port 10, and discharges stagnant and humid air under the floor 9 from the exhaust port 4 to the outside. . By repeating this operation, the humidity of the underfloor 9 is reduced, the moisture content of the wood constituting the underfloor 9 is reduced, and the activity of wood rot fungi or the activity of mold is suppressed.

When the controller 11 has a built-in humidity sensor, the operation of the ventilation fan body 2 is stopped when the humidity of the outside air is high, such as when it is raining, and the ventilation fan body 2 is stopped only while the outside air is at low humidity. It is something to drive.

[0006]

The underfloor ventilation fan having the above-mentioned structure has a problem that the ventilation function is not sufficient. In other words, when the operating time of the underfloor ventilation fan is raining, or when the humidity of the outside air is high, such as after the rainfall, the outside air having a high humidity is taken under the floor. For this reason, conversely, the humidity under the floor is increased, and the moisture content of the wood is increased. When the controller 11 has a built-in humidity sensor, the operation is stopped while a long-term high humidity state such as the rainy season continues. That is, the operation is kept stopped when drying by ventilation is originally required.

Further, even when the humidity of the outside air is low,
The relative humidity of the air under the floor (wash room, etc.) on the north side where the underfloor ventilation fan is installed does not decrease so much. In other words, the temperature of the outdoor air sucked into the underfloor 9 from the ventilation hole on the south side is reduced by the heat capacity of the building before reaching the washroom on the north side, etc. Cannot be reached.

Further, as shown in FIG. 9, when the underfloor ventilation fan is stopped at 4 pm, the underfloor humidity rapidly increases, and the environment is kept high in the morning from the evening until 10 am when the underfloor ventilation fan operates. Maintained, almost 3/4 of the day in high humidity.

[0009] As described above, the conventional underfloor ventilation fan is operated from around 10 am to 4 pm when the temperature of the outside air rises and the humidity becomes low.
It only keeps the environment under the floor at low humidity until about the time, and does not operate when the outside air is in a high humidity state or during the evening to morning. Therefore,
The effect of reducing the moisture content of the wood under the floor and suppressing the activity of rot fungi or the activity of mold cannot be sufficiently exerted.

[0010]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional construction, and includes a dehumidifying means or a ventilating means for dehumidifying and ventilating under the floor together with a drug such as an antibacterial treatment agent. By spraying under the floor, regardless of the humidity condition and time of the outside air, the entire area under the floor can be effectively dried and antibacterial and insect repellent, of course, especially under the northern floor of washrooms, bathrooms, kitchens etc. It is a ventilation dehumidifier that can process.

Further, the blower means 17 and the second switching valve 25 constitute a ventilation means, and blow the outside air taken and blown by the blower means 17 from the second blower port 24 and the blower port 26 to the lower floor 9. is there.

Reference numeral 27 denotes a ventilation panel which is connected to the ventilation port 10 and attached to the building.
Connected at 8. 29 is a detecting means for detecting the humidity of the outside air, and 30 is a control means for operating the dehumidifying means or the ventilation means according to the detected humidity of the detecting means 29.

In this embodiment, the medicine releasing means 3 for releasing a medicine such as an antibacterial treatment agent or an insect repellent treatment agent into the air outlet 26 is provided.
1 is arranged. The medicine releasing means 31 is configured to pressurize the medicine and atomize it with a spray nozzle and supply the atomized air to the blowing port 26, or heat the mat containing the medicine such as an antibacterial treatment agent or an insect repellent treatment by a heating means. And the like that evaporate is considered. As a drug having an antibacterial function, hinokitiol, ethanol, benzalkonium chloride, etc., as a drug having an insect repellent function, chlorhexidine, glutaraldehyde, sodium hypochlorite, etc. are used at appropriate concentrations. I have. The medicine control means 32 controls the medicine release means 31 to control the medicine release amount, the operation time, and the like.

As the adsorbent 19, granular silica gel,
Alternatively, a zeolite or the like filled in a gas-permeable container, or a honeycomb structure having a passage section in a lattice or hexagonal shape is used.

The first switching valve 23 and the second switching valve 25 are
It is composed of a drive source such as a motor and an electromagnet (not shown) and a partition plate. The blowing means 17 is constituted by a fan motor and a casing.

The operation of the embodiment will be described below. When the detection unit 29 detects the outside air humidity at 10:00 am, which is the operation start time of the ventilation dehumidifier, and the control unit 30 recognizes that the outside air humidity is lower than the set value and the outside air is dry, the ventilation operation is performed. I do. That is, the second switching valve 25
Is set to the a side shown in FIG. 1 and the blowing means 17 is operated. The air blowing means 17 draws in the low-humidity outdoor air from the air inlet 16, and outputs the low-humidity outdoor air from the air blowing port 26 in FIG.
Air is blown into the underfloor 9 as shown by the arrow a in the middle. This dry air dries the wood constituting the underfloor 9 and reduces the moisture content of the wood. The control means 30 simultaneously drives the medicine control means 32 to cause the medicine release means 31 to release a medicine such as an antibacterial treatment agent or an insect repellent treatment agent. This medicine is sprayed under the floor 9 together with the low-humidity outdoor air blown by the blowing means 17 from the blowing port 26. As shown in FIG. 2, the control means 30 drives the medicine control means 32 for a predetermined time simultaneously with the start of the operation of the air blowing means 17 to cause the medicine release means 31 to release the medicine. Further, after the operation of the medicine control means 32 is completed, the blowing means 17 is continuously operated for a predetermined time. That is, the control means 30 terminates the operation of the blowing means 17 constituting the ventilation means after ending the delay operation for a predetermined time after the medicine releasing operation of the medicine releasing means 32 is completed.

In other words, the medicine to be sprayed is in the form of an aqueous solution, and the water of the aqueous solution adhering to the wood constituting the underfloor 9 is dried by this delayed operation, and is fixed to the wood in a high concentration. is there.

In this way, even after the stop time of the ventilation operation at 4:00 pm, even if the humidity under the floor 9 becomes high, the chemicals adhere to the surface of the wood at a high concentration, and the activity of the decay fungus or the activity of the mold is increased. Can be suppressed.

1 am, which is the operation start time of the ventilation dehumidifier
If the outside air humidity at 0:00 is higher than the set value, the control unit 30 starts the dehumidifying operation. That is, the dehumidification mode operation is executed as the first operation state. That is, the second switching valve 25 is set to the “b” side shown in FIG. 1 and the first switching valve 23 is set to the “a” side, and the blowing unit 17 is operated. Blowing means 17
Is operated, the humid outdoor air is sucked from the inlet 16. This outdoor air flows through the ventilation path 18 and the adsorbent 19
Contact with. The moisture in the air is adsorbed by the adsorbent 19 by contact with the adsorbent 19, and the outdoor air becomes dry air with low humidity. At the same time, the dry air becomes hot due to the heat of condensation of moisture given by the adsorbent. The high-temperature dry air flows through the first air outlet 21 and the air outlet 26 because the first switching valve 23 is on the side A, and is blown to the underfloor 9 as shown by the arrow b. Is done.

Therefore, the stagnant high-humidity air in the underfloor 9 is supplied to the ventilation port 1 other than the place where the dehumidifying ventilation device body 15 is installed.
The water content of the wood constituting the underfloor 9 can be reduced by the low-humidity dry air that is exhausted from 0 to the outside and blown out from the blower opening 26. At this time, the control means 30
At the same time, the medicine control means 32 is driven to operate the medicine release means 31. As described above, the medicine released by the medicine releasing means 31 is sprayed under the floor 9 together with the dry air. Further, at this time, the control unit 30 terminates the operation of the medicine control unit 32 for a predetermined time as described above,
The blowing means 17 is operated continuously for a predetermined time.
In this way, a high concentration of the drug is fixed on the surface of the wood under the floor 9.

As described above, when the adsorbent 19 adsorbs a large amount of water and the activity is reduced by continuing the dehumidification mode operation of the first operation state for a predetermined time, the control means 30 performs the regeneration operation of the second operation state. Execute mode operation. That is, the regenerative heating means 20 and the air blowing means 17 are operated with the second switching valve 25 on the b side and the first switching valve 23 on the b side. The air blown by the blowing means 17 is heated by the regeneration heating means 20 to a high temperature and comes into contact with the adsorbent 19. The adsorbent 19 is heated by the contact of the high-temperature air, and releases the adsorbed moisture. Thus, the adsorbent 19 recovers its activity. Adsorbent 19
The high-humidity air containing the water released from the air outlet is exhausted from the exhaust port 22 to the outside of the main body 15 because the first switching valve 23 is on the side B.

In this embodiment, the control means 30 does not drive the medicine control means 32 during the regeneration mode operation. That is, the operation of the medicine releasing means 31 is stopped.

When the regeneration mode operation is executed for a predetermined time and the adsorbent 19 recovers its activity, the control means 30 executes the dehumidification mode operation which is the first operation mode again. By repeating the dehumidification mode / regeneration mode, the drying of the underfloor 9 proceeds.

According to this embodiment, the end time of the dehumidifying operation does not need to be limited to around 4:00 pm when the outdoor temperature decreases and the humidity increases. That is, even when the outdoor air is in a high humidity state, the above-described dehumidification mode operation can be performed to supply the dry air, so that the end time can be freely set.

As described above, according to the present embodiment, the antibacterial treatment is performed when the dry air is blown or the ventilated air is blown by the medicine releasing means provided in the ventilation path in which the dehumidifying means or the ventilation means blows outside air under the floor. It is a ventilation and dehumidifier that can spray chemicals and insect repellents.

Further, the control means activates the dehumidifying means when the humidity of the outside air is equal to or higher than a preset humidity, activates the ventilation means when the humidity is less than the preset humidity, and activates the medicine releasing means when the dehumidifying means operates, or The ventilation and dehumidifying device can be operated when the means is operated or when both are operated, so that the medicine can be sprayed efficiently.

The control means is configured to terminate the operation of the dehumidifying means or the ventilation means after ending the operation of the medicine releasing means, ending the delay operation for a predetermined time, and thereafter ending the operation of the medicine adhering to the wood. The underfloor ventilator, which evaporates water and has a high concentration, can suppress the activity of rot fungi and mold.

In this embodiment, the detecting means 29 detects the humidity of the outside air. However, the detecting means 29 detects the humidity of the underfloor 9 and the detecting means of the outside air. It is also possible to adopt a configuration in which the device 30 is operated by selecting a dehumidifying unit and a ventilation unit.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 3 shows the configuration of this embodiment. In this embodiment, the drug concentration detecting means 35 for detecting the drug concentration is arranged near the ventilation port 10 on the opposite side where the ventilation dehumidifier body 15 is installed below the floor 9 as shown in FIG. 36 is a medicine concentration detection means 35 and a medicine control means 3
7 is a signal line for connection to the signal line 7. The medicine control means 37 operates the medicine release means 31 according to the detection level of the medicine concentration under the floor 9 detected by the medicine concentration detection means 35. In addition, as the drug concentration detecting means 35, a quartz oscillator is provided in an appropriate housing, and the entire drug concentration is estimated by measuring the amount of drug deposited on the quartz oscillator within a predetermined time. Use things. Further, the installation position of the drug concentration detecting means 35 does not need to be particularly limited to the position shown in FIG.

The operation of this embodiment will be described below. When the humidity of the outside air is lower than the set value and the outside air is dry, the ventilation operation is performed. That is, the low-humidity outdoor air is sucked in from the air inlet 16 by the air blowing means 17, and the low-humidity outdoor air is blown into the underfloor 9 from the air blowing port 26. The medicine is discharged to the air outlet 26. Thus, both the dry air and the medicine are blown and sprayed under the floor 9, and the floor 9 is dried. By continuing this ventilation operation, the detection level of the drug concentration detecting means 35 installed under the floor 9 rises, and when the drug control means 37 recognizes that the drug concentration has reached the set level, the operation of the drug releasing means 31 is started. To end. Thereafter, as in the first embodiment, the control means 30 controls the blowing means 17.
Is operated for a predetermined time delay.

When the humidity of the outside air is higher than the set value, the dehumidification mode operation as the first operation mode of the dehumidification operation and the regeneration mode operation as the second operation mode are repeated at predetermined time intervals. In the dehumidification mode operation, the blowing means 17
The moisture in the air taken in from the intake port 16 is adsorbed by the adsorbent 19, and the high-temperature dry air that has received the heat of adsorption is blown from the first blower port 21 and the blower port 26 to the floor 9 below. is there. At this time, the control means 30 controls the medicine control means 37
Is driven to release the drug from the drug releasing means 31 in the same manner as described above. Further, the medicine control means 37 stops the release of the medicine from the medicine release means 31 when the concentration information of the medicine concentration detection means 35 is reached and the medicine concentration reaches a predetermined level. Further, the control means 30 includes the medicine releasing means 3
Even after the stop of operation 1, the air blowing means 17 is operated for a predetermined time delay.

At this time, if the medicine concentration detecting means 35 is installed not only at one place but also at a plurality of places, the medicine can be sprayed all over the area 9 under the floor.

As described above, in the present embodiment, it is possible to spray a medicine at a predetermined concentration together with the dry air blown under the floor 9, thereby realizing a user-friendly ventilation and dehumidifier.

(Embodiment 3) Next, a third embodiment of the present invention will be described. In the present embodiment, as shown in FIG. 5, the medicine releasing means 34 is provided in the first air outlet 21. The medicine releasing means 34 used in the present embodiment may be a mat containing a medicine such as an antibacterial treatment agent or an insect repellent treatment agent, or a medicine container (see FIG. (Not shown)). As this drug, hinokitiol or the like extracted from cypress is mixed at an appropriate concentration.

The operation of this embodiment will be described below. When the control unit 30 recognizes that the humidity of the outside air is lower than the set value and the outside air is dry, the ventilation operation is performed. That is, the blowing means 17 draws in low-humidity outdoor air from the intake port 16 and blows this outdoor air from the blowing port 26. In the case of this ventilation operation, the blast air does not pass through the medicine releasing means 31, so that the medicine is not released to the underfloor 9. When the humidity of the outside air is higher than the set value, the operation in the dehumidifying mode and the regeneration mode of the dehumidifying operation is repeatedly performed at predetermined time intervals. When the first regeneration mode ends and the operation in the dehumidification mode is started, the outside air sucked from the air inlet 16 by the air blowing means 17 comes into contact with the adsorbent 19 and becomes low-humidity and high-temperature dry air. The high-temperature dry air is blown from the first blower port 21 to the underfloor 9 through the blower port 26. At this time, in the present embodiment, the medicine releasing means 34 is provided in the first air outlet 21. Therefore, the drug release means 34
Is heated by high-temperature dry air passing through the first air outlet 21. In other words, the medicine contained in the medicine releasing means 34 is heated and evaporated by the heat of the dry air, and is sprayed together with the air to be blown from the air outlet 26 under the floor 9.

At this time, the first air outlet 21 has a considerably large heat capacity, and has a sufficient amount of heat even when switched to the dehumidification mode operation due to the influence of heat generated by the regeneration heating means 20 in the regeneration mode operation. Therefore, according to the present embodiment, the medicine can be released by driving the medicine releasing means 34 without requiring a special heat source.

FIG. 6 is an explanatory diagram for explaining the driving state of the medicine releasing means 34. When the medicine releasing means 34 is constituted by a mat containing a medicine, the medicine releasing means 34 can be removably stored in the first air outlet 21 and the exchange of the medicine releasing means 34 can be very easily performed.
