Description

TECHNICAL FIELD The present invention relates to a simple indoor humidity control device that can control the indoor humidity of a building by intermittent operation during mist discharge time.

Conventionally, indoor humidity control in a building is generally performed with a tank-type humidifier placed on the floor of the room when large-scale air conditioning equipment is not used (see, for example, Patent Document 1).

However, such a tank-type humidifier has a problem that replenishment of water for humidification, operation of the humidifier, confirmation of humidity, etc. must be frequently performed manually. In addition, it is very difficult to maintain a desired humidity while appropriately adjusting humidification to every corner of a large room. Furthermore, when the water for humidification is not used continuously, the released water mist generates an odor, which poses a hygiene problem.

FIG. 4 is a schematic explanatory diagram of another example of the indoor humidity control device of the present invention.

An example of an embodiment of the indoor humidity control device of the present invention will be described with reference to the drawings as appropriate, but the present invention is not limited to these.

The indoor humidity control device of the present invention can be used in a building room, for example, an indoor space where people enter and leave, especially an office space or an article storage warehouse, based on the humidity measurement data of the humidity measurement device. is intended to be controlled by intermittent operation, and fine humidity control in a wide range of indoor spaces can be easily and quickly performed.

FIG. 1 schematically shows an example of the indoor humidity control device of the present invention. As shown in FIG. 1, the indoor humidity control device 1 of the present invention includes an indoor pipe 2, a water supply device 3 configured to supply tap water (normal water is also possible) to the indoor pipe 2, A plurality of nozzles 4 which are provided at intervals in indoor piping and which convert tap water in the indoor piping 2 into mist and emit it, a humidity measuring device 5 which measures the indoor humidity, and the mist emitted from the nozzle 4. and a control device 6 for controlling the time or dose or the like.

As shown in FIGS. 2(a) and 2(b), the indoor pipe 2 is arranged so as to extend along the ceiling of the room in consideration of the location where the mist is to be emitted. The indoor pipe 2 is generally made of conventionally known materials such as plastic resin such as polyethylene and vinyl chloride, stainless steel, copper, and rubber, and preferably has an inner diameter of about 2 to 10 mm. Installation of the indoor pipe 2 on the ceiling can be performed by suspending it from the ceiling using a fixture that can fix the ceiling and the indoor pipe 2 as shown in FIG. can be embedded in the ceiling so that only the mist outlet of the nozzle 4 is exposed from the ceiling.

Chlorine-sterilized tap water is preferably supplied to the indoor piping 2 from a sanitary point of view. As the water supply device 3, conventionally known devices can be appropriately adopted. A device configured to send tap water to the indoor pipe 2 by activating a high-pressure pump can be mentioned.

As shown in FIG. 1, the indoor pipe 2 is provided with a plurality of nozzles 4 at intervals, preferably at regular intervals. The installation interval of the nozzles 4 is preferably set to 30 to 200 cm. The number of nozzles 4 depends on the length of the indoor pipe 2, but is preferably 2 to 50, more preferably 3 to 20, more preferably 5 to 10 per indoor pipe. The nozzle 4 is attached to the indoor pipe 2 so that tap water sent into the indoor pipe 2 by the operation of the high-pressure pump can be converted into mist and discharged into the room in a substantially horizontal direction. The average particle size of the mist discharged from the nozzle 4 is preferably 10 to 30 μm. The average particle size of this mist is smaller than that of mist emitted from fire extinguishing equipment such as sprinklers. If the average particle size of the mist is less than 10 µm, the nozzle tends to be clogged. As the nozzle 4, a conventionally known one-fluid nozzle can be employed, and one having a function of pulverizing a liquid (tap water) under high pressure to form a fine mist and release a mist is preferable. Further, the nozzle 4 is preferably capable of controlling the opening and closing of the mist outlet.

As shown in FIG. 1, the humidity measuring device 5 is arranged at or near a place where it is desired to keep the indoor humidity constant, for example, on the wall of a pillar or the like, and is configured to measure the indoor humidity at that place. there is The humidity measuring device preferably measures humidity as well as other environmental data such as temperature. A plurality of humidity measuring devices 5 are preferably provided at intervals, and preferably one below each nozzle 4 of the indoor pipe 2 in terms of accuracy of indoor measurement data. As the humidity measuring device 5, any device having a conventionally known humidity measuring function as shown in FIG. 3 can be adopted. to the control device 6 by radio. Humidity measurement does not have to be continuous, it may be intermittent, and it is sufficient to perform it at regular intervals, for example, 1 minute to 2 hours, or 5 minutes to 1 hour.

The control device 6 is configured to be able to control the release time of mist from the nozzle 4 and, if necessary, the release amount according to the humidity value measured by the humidity measurement device 5 . For example, when the measured humidity value is lower than a specific value (desired value), the control device 6 continues to emit mist from the nozzle 4 for a certain period of time in order to increase the indoor humidity value, and then When the measured humidity value reaches the above-mentioned specific value, it is controlled to stop the ejection of mist from the nozzle 4 . Alternatively, if the measured humidity value is lower than a specific value (desired value), the mist emission time from the nozzle 4 and, if necessary, the emission amount can be set according to the difference between the values. Specifically, if the difference between them is large, the mist emission time is lengthened, and the emission amount is increased as necessary, and if it is small, the mist emission time is shortened, and the emission amount is reduced as necessary. can be set as In these cases, the measured humidity values are preferably intermittent measurements rather than continuous measurements. This is because it takes a certain amount of time to reflect the increase in humidity due to the ejection of mist from the nozzle 4 . As the control device 6, conventionally known devices in this field can be appropriately adopted, but it is preferable to use a programmable logic controller (PLC) used for machine control. Moreover, the control device 6 preferably has a wireless or wired communication function with the humidity measuring device 5 or the like. It is preferable that stored data such as measured humidity and mist release control in the control device 6 can be confirmed on a tablet that can communicate using Wifi, and this stored data can be used as history data using a cloud service. It is preferable that it can be downloaded to a PC or sent by e-mail to a smartphone.

When a plurality of humidity measuring devices 5 are provided at intervals, the control device 6 determines that the difference in the measured humidity value between two specific humidity measuring devices 5 is a specific value or more (for example, 2% or more, or 3% or more), mist is emitted from the nozzle 4 near the humidity measurement device 5 with the lower humidity measurement value (or the mist emission time is lengthened), and the humidity measurement device with the higher humidity measurement value It is possible to control so that mist is not emitted from nozzles 4 near 5 (or mist emission time is shortened). For example, referring to FIG. 4, when the measured humidity value of the lower left humidity measuring device 5' is low and the measured humidity value of the upper right humidity measuring device 5'' is high, the humidity measuring device 5' is close to the lower left humidity measuring device 5'. It is possible to control so that the mist is emitted from the nozzle 4 and is not emitted from the nozzle 4 close to the humidity measuring device 5'' on the upper right side. As a result, it is possible to easily and appropriately equalize the slightly different humidity generated in each place in the room.

When a plurality of humidity measuring devices 5 are provided at intervals, the control device 6 designates the humidity measuring device 5 that measures the humidity value used for controlling the mist emission time from the nozzle 4 among them. be able to. As a result, the humidity control near the specified humidity measuring device 5 can be properly performed as desired.

When a plurality of humidity measuring devices 5 are provided at intervals, the control device 6 weights the measured humidity value of each humidity measuring device 5, and controls the nozzle 4 based on the humidity value calculated according to the weighting. It is possible to control the release time of the mist from. As a result, it is possible to appropriately perform humidity control by emphasizing the vicinity of the place where the humidity measuring device 5 with a higher weight is present.

The control device 6 can control the temperature of the tap water supplied to the indoor piping to be higher than the room temperature. As a result, it is possible to prevent the room temperature from dropping due to the vaporization heat of the mist while the mist is being emitted from the nozzle 4. - 特許庁For example, the controller 6 can instruct the tap water supplied in the thermostatted water supply 3 to be warmed.

The indoor humidity control device of the present invention can be provided with a human sensor (not shown) in the room (for example, at the entrance of the room). The emission of mist can be stopped or controlled to shorten the duration of mist emission. As a result, it is possible to prevent people from being exposed to the mist when there are people in the room and to prevent people from being conscious of the mist.

Regardless of the humidity value measured by the humidity measuring device 5, the control device 6 can control the discharge of mist from the nozzles at regular time intervals. For example, if the mist is released after the mist has been stopped for a long period of time, an offensive odor will be generated even if chlorinated tap water is used as the raw material. and amount of mist can be emitted. Conversely, if the cycle of ON/OFF control for mist emission from the nozzle is short, the life of the control relay will be shortened and it will easily break down. A long ON/OFF period can be set (for example, one hour or more). Furthermore, the amount of mist required to achieve the desired humidity is calculated from the volume and temperature of the room in which the indoor humidity control device of the present invention is installed, and the mist release time (ON / OFF time) in one day In addition, the release amount can be pre-determined if desired.

The indoor humidity control device of the present invention can be provided with a water droplet sensor (not shown) on the indoor floor below the nozzle. It can be controlled to stop. As a result, it is possible to prevent water droplets from falling on the floor and flooding the floor when an abnormality such as poor mist formation from the nozzle occurs.

As shown in FIG. 4, the indoor humidity control device of the present invention can be provided with a plurality of indoor pipes 2 having a plurality of nozzles 4 independently. The number of independent indoor pipes depends on the size of the room, but is generally 2-100, preferably 3-20, more preferably 5-10. This makes it easier to fine-tune humidity control for each location in the room when the nozzles attached to one indoor pipe are designed to emit the same amount of mist, or when the indoor space is large. Because. As a result, it is possible to adopt a structure in which pressurized water flows only in the direction of the necessary indoor pipes, and fine humidity control is possible by discharging mist for each indoor pipe.
