Description

  The present invention relates to an air circulation and dehumidification device, and more specifically, in a house or the like that grows vegetables and the like, air that has stopped in the upper and lower layers is circulated to promote carbon assimilation of the crop, and the space of the entire house is constant It is related with the air circulation and dehumidification apparatus which can reduce the heating expense of winter by reducing the loss of the hot air which has stopped in the upper layer of a house through the ceiling so that it may become temperature distribution of this.

Generally, a greenhouse or the like is used to grow vegetables and crops that are difficult to grow in winter. In order to enhance the greenhouse effect, the greenhouse is blocked by vinyl so that outside air does not pass through, and the temperature is maintained in the house using a heating device or a coal fireplace. As described above, the temperature in the greenhouse is maintained by using a heating device, a fireplace, or the like. Recently, as the size of the greenhouse increases, the heating cost is also increasing.
Also, the temperature distribution in the greenhouse is such that the temperature of the upper layer is high due to the difference in air density, and the temperature of the lower layer close to the ground is maintained at a relatively low rate. Therefore, the hot air that is concentrated on the upper layer of the greenhouse comes into contact with the cold surface of the ceiling of the greenhouse and quickly takes the heat source out.

  In this way, the heat in the greenhouse will be quickly taken away to the outside, and it will be necessary to raise the temperature again by operating a heating device etc. in the greenhouse that must maintain a constant temperature as a whole. As a result, further fuel is consumed, which is uneconomical. Furthermore, when a greenhouse is heated using a heating device or the like, a considerable difference occurs in the temperatures of the upper, middle, and lower portions of the house, which has a problem of acting as an inhibitory factor in crop growth.

  When the hot air heater is operated to adjust the temperature inside the greenhouse, the humidity inside the house will rise. In this case, when an object that was in a cold place suddenly moves to a hot place, A phenomenon that water droplets form on the surface occurs. As a result, the humidity in the greenhouse rises momentarily, so that the humidity for growing the crop cannot be adjusted appropriately, and there is a disadvantage that hinders the growth of the crop.

  Due to the characteristics of the greenhouse, the metabolism and carbon assimilation required for growth are reduced, and the growth of crops is delayed, which not only lowers productivity but also causes pest damage as well as cold damage due to temperature differences. . Therefore, recently, in order to maintain a uniform temperature distribution of air inside a greenhouse such as a greenhouse, a fan 6 is provided in the cylindrical body 4 as shown in FIG. It has been proposed to operate the air agitating device over the ceiling of the house 2 using the chain 8.

When the fan 6 provided in the cylindrical main body 4 is operated, the hot air on the upper side is moved to the lower side through the diffusion plate 10, and the cold air on the lower side is moved to the upper side, and housed by convection. The temperature distribution inside is made uniform. At this time, however, the water vapor distributed in the house is also moved with the air and continuously circulated without lowering the humidity in the house. This will lead to undesirable results. As a result, the yield is significantly reduced as the amount of cultivation is reduced, and thus there is a problem inferior in economic efficiency.

  As shown in FIGS. 2 and 3, the air circulation and dehumidifying device of the present invention has an upper opening 22 and a lower opening so that the upper side air and the lower side air in the house can move up and down. A cylindrical body 20 having a portion 24 is provided. A circulation fan 26 for moving air to the lower side is provided inside the cylindrical main body 20, and the circulation fan 26 is driven by a motor 21. On the lower side of the cylindrical main body portion 20, there is provided a wind direction diffusing portion 37 that can diffuse and move the air moved by the circulation fan 26 to the outer diameter side of the cylindrical main body portion 20.

  A dehumidifying semiconductor element 30 having a heating pad 32 and a cooling pad 34 for dehumidification is provided on the outer periphery of the wind direction diffusion portion 37. The dehumidifying semiconductor element 30 has a configuration in which when a current is applied, the heating pad 32 generates heat and the cooling pad 34 in contact with the heating pad 32 is cooled. This is a characteristic of the semiconductor element 30 for dehumidification, and when current flows through different metals, one of them has a characteristic that the temperature is lowered and the other is acted on by the Peltier effect that raises the temperature. The dehumidifying semiconductor element 30 must operate to lower the temperature of the cooling pad 34 in order to remove water vapor contained in the air. As the temperature of the cooling pad 34 decreases, heat is generated in the heating pad 32 formed so as to abut on the opposite side. Accordingly, the heating pad 32 adhering to the opposite side of the cooling pad 34 is disposed so as to abut on the heating coil piece 31 having a large divergence effect in order to quickly dissipate heat and lower the temperature. . As described above, when the cooling pad 34 of the semiconductor element 30 is cooled, the temperature of the heating pad 32 is further increased. Therefore, if this is cooled quickly, the dehumidifying effect of the cooling pad 34 can be enhanced.

  On the upper side of the heating pad 32, the heating coil piece 31 is formed in a donut shape over the entire area on the wind direction diffusing portion 37 in order to cool the generated heat smoothly. Thus, in order to form the heating coil piece 31 in the whole area on the wind direction diffusion part 37, it is comprised so that the heat which generate | occur | produces from the heating pad 32 may be disperse | distributed and conducted with a wider distribution degree. Further, the heat generated by the heating pad 32 conducted to the heating coil piece 31 is naturally cooled by the air generated by the circulation fan 26.

  A disk-shaped heating coil piece 31 for heat exchange is provided on the wind direction diffusing portion 37 in order to more quickly diffuse the heat generated from the heating pad 32 over the entire upper surface. In addition, a disk-shaped heat exchange plate 28 in which a hole 29 through which inflow air passes is formed in the thickness direction is provided on the upper surface of the heating coil piece 31.

  A dehumidifying piece 40 is provided on the surface of the cooling pad 34 to liquefy the incoming water vapor into water droplets.

  Reference numeral 60 denotes a power supply unit provided on the wind direction diffusing unit 37 so as to supply power to the dehumidifying semiconductor element 30.

  A heating pipe 55 for smoothly diffusing heat generated from the dehumidifying semiconductor element 30 is provided on the entire surface of the heating coil piece 31 provided on the wind direction diffusing portion 37.

  Reference numeral 80 denotes an air adjusting damper that adjusts the amount of air flowing into the moisture removing unit 50.

  Hereinafter, the operation of the indoor air circulation and dehumidifier of the present invention configured as described above will be described in detail.

  As shown in FIGS. 2 and 3, in the air circulation and dehumidification device of the present invention, the cylindrical main body 20 is provided at an appropriate height in the house using a chain 100 or the like.

The circulation fan 26 provided on the inner side of the cylindrical main body 20 allows the upper side air and the lower side opening 24 of the cylindrical main body 20 to pass through the upper side air and the lower side air on the ground surface that are stopped on the ceiling in the house. Move to forcibly circulate through. When the rotation direction of the motor shaft is changed by the motor 21 provided in the center of the cylindrical main body 20, the circulation fan 26 is disposed on either side of the upper opening 22 and the lower opening 24 of the cylindrical main body 20. The flow of incoming air can be reversed. The circulation fan 26 provided on the inner diameter side of the cylindrical main body 20 is used to forcibly circulate the internal air stagnating on the ceiling and ground of the house. The circulating air inside the house that is forcibly circulated by the circulation fan 26 is circulated by the wind direction diffusing portion 37 provided in the upper opening 22 or the lower opening 24 of the cylindrical main body 20 to the entire space in the house. Can be diffused smoothly. The air discharged from the cylindrical main body 20 by the wind direction diffusing section 37 is discharged in the direction of 360 ° on the outer peripheral side.

  In particular, since the house is heated in the winter, hot air is constantly rising to the ceiling of the house. Therefore, when warm air stagnates on the ceiling side of the house, the heat source is lost outside the house through the ceiling side. Therefore, the circulation fan 26 provided in the cylindrical main body 20 as described above is used primarily. Circulate the upper and lower air in the house. In this way, when the air in the house is circulated by the circulation fan 26, the warm air on the upper side stagnant in the ceiling of the house falls to the ground surface side, warming the ground surface side where the crop is growing, Since the low-temperature air remaining on the surface is moved to the ceiling side and circulated, it is possible to prevent the heat source from being lost to the outside through the surface of the ceiling.

  At this time, the hot air on the ceiling side that is moved downward by the circulation fan 26 passes through the upper opening 22 of the cylindrical main body 20, and then enters the wind direction diffusion portion 37 formed on the lower side of the lower opening 24. It is guided to be discharged along. As shown in FIG. 6, the wind direction diffusing unit 27 is configured to smoothly diffuse the air discharged from the lower opening 24 through the cylindrical main body 20 in the outer peripheral direction of the cylindrical main body 20 as shown in FIG. It is preferable to have a gradient of ° to 20 °. As described above, when a gradient is given to the wind direction diffusing unit 27, the air that is moved against the wind direction diffusing unit 27 is smoothly moved along the curved portion of the gradient. In particular, in winter, it is preferable to position the wind direction diffusing portion 37 on the lower opening 24 side of the cylindrical main body portion 20.

  As described above, the air that is moved by the circulation fan 26 is hot air that remains on the ceiling on the side of the upper opening 22 by the wind direction diffusing portion 37 and is stopped along the cylindrical main body 20 through the lower opening 24. Discharged. At this time, the warm air flowing in from the ceiling side discharged by the wind direction diffusing section 37 is diffused and discharged to the lower side of the house, and rises while pushing out the cold air stagnating on the ground surface of the house to the upper side. The cold air and the hot air are mixed together, so that the air maintains a constant temperature distribution.

In the present invention, not only the circulation of the air in the house but also the air that has flowed into the cylindrical main body 20 for dehumidification is discharged to the lower opening 24 side, so that the upper side of the wind direction diffusion part 37 Is flown into the hole 29 of the disk-shaped heat exchange plate 28 formed in the above, or hits the heat exchange plate 29 and is discharged to the side surface. The air flowing into the hole 29 of the disk-shaped heat exchange plate 28 is moved between the heating coil pieces 31 installed in contact with the disk-shaped heat exchange plate 28, and the heating coil pieces. 31 is discharged in the lateral direction. That is, a part of the air discharged to the lower opening 4 of the cylindrical main body 20 is discharged through the disk-shaped heat exchange plate 28 and the heating coil piece 31, and a part thereof is below the wind direction diffusion part 37. It flows into the provided moisture removal unit 50.
The circulated air collides with the wind direction diffusing portion 37, a part is discharged to the side surface, and a part is easily flowed into the moisture removing portion 50 through the perforated air inflow hole 56.

  The air containing water vapor that has flowed into the lower side of the heating coil piece 31 partially flows into the moisture removing unit 50 and contacts the surface of the dehumidifying piece 40 on the cooling pad 34 of the semiconductor element 30 for dehumidification. Is passed. The dehumidified piece 40 cooled by the cooling pad 34 is brought into contact with the cooled dehumidified piece 40 surface through the inflow hole 56 formed so as to penetrate the wind direction diffusing portion 37, and the temperature rapidly decreases. Therefore, it liquefies and becomes water droplets. If the temperature of the dehumidifying piece 40 is too low and water vapor in the air comes into contact and freezes, increasing the amount of air flowing into the moisture removing unit 50 side will release the frozen and water droplets. Will fall.

  As described above, when the water vapor contained in the air is liquefied on the cold surface by the dehumidifying piece 40 to form water droplets, and the amount of water droplets falling on the lower side of the moisture removing unit 50 increases, the moisture removing unit 50 is discharged through a water drain port 52 provided on the lower side of 50. The water that is liquefied and falls to the dehumidifying piece 40 is discharged through the water drain 52 of the moisture removing unit 50 and collected in one place and can be reused. Further, the air from which the water vapor has been removed by the dehumidifying piece 40 is discharged and moved through the air discharge ports 54 provided on one side or both sides of the moisture removing unit 50. Thus, if the water vapor contained in the air circulated by the air circulation and dehumidifier of the present invention is smoothly removed, the temperature distribution in the house can be maintained uniformly.

  The reason why the moisture removing unit 50 of the present invention is configured by covering the moisture removing unit 50 so as to surround the dehumidifying piece 40 from which the water vapor contained in the air is removed is formed on the wind direction diffusing unit 37. This is to remove a large amount of water vapor contained in the air by causing the air flowing into the air inflow hole 56 to hit the dehumidifying piece 40 as much as possible.

  In the present invention, the power supply unit 60 that operates the circulation fan 26 and the semiconductor element 30 for dehumidification is very sensitive to moisture because a current flows and a substrate or the like is built inside. Therefore, it is preferable that the power supply unit 60 is formed so as to be positioned on the lower side of the wind direction diffusing unit 37, which is not affected by space utilization, water vapor in the air, etc. .

  The present invention is also configured to adjust the size of the inflow hole 56 on the wind direction diffusion part 37 in order to adjust the amount of air flowing into the moisture removal part 50 as shown in FIG. The necessary amount of dehumidification can be adjusted by adjusting the air-conditioning damper 80. A damper hole 84 is formed in the air adjusting damper 80 so that the air can be adjusted more finely. Therefore, since the length of the damper hole 84 can be adjusted by loosening the wing nut 82 that fixes the air adjustment damper 80, the size of the inflow hole 56 of the moisture removing unit 50 can be adjusted. ing.

  Next, an example in which the air circulation and dehumidifying device of the present invention is applied in summer will be specifically described. Most of the houses used in the summer are installed and used in a hydroponically cultivated house, but it goes without saying that this is not necessarily limited to a hydroponically cultivated house.

  In summer, due to the characteristics of the climate, there is a considerable amount of geothermal heat that rises to the surface of the earth, and the closer to the ground surface the higher the temperature of the geothermal heat. Due to these characteristics, the temperature inside the house belongs to the upper part of the house where the temperature is lower than the ground surface, and the temperature of the ground surface belongs to the higher one. To occur. Therefore, at present, in order to lower the temperature of the house in summer, outside air is introduced into the house to maintain the temperature inside the house uniformly. There is a problem that it can cause serious damage to crops because it is in contact with the temperature of the sun, so it prevents outside air from flowing into the house in climates such as the rainy season.

  Cooling to lower the temperature in the house during summer is energy consuming, so the fact is that the method of lowering the temperature in the house with water is widely used without using this. It is.

  For this reason, there is a problem that the humidity in the house becomes considerably high, but the humidity can be lowered by using the air circulation and dehumidifying device of the present invention.

  In the above description, the air circulation and dehumidification apparatus of the present invention is used when heating is performed at a cold time such as in winter, and when hot air is stopped on the ceiling side of the house, as opposed to when hot air is stopped on the ceiling side of the house. As shown in FIG. 5, the wind direction diffusing portion 37 may be installed on the upper side of the cylindrical main body portion 20. As described above, the cooling pad 34 of the dehumidifying semiconductor element 30 can be provided outside the wind direction diffusing portion 37 to remove water vapor contained in the discharged air. That is, contrary to the configuration used in winter, the air direction diffusing unit 37 is attached to the upper side of the cylindrical main body 20 with the air circulation and dehumidifying device turned upside down, and the ground in the house is used by using the circulation fan 26. Move the air remaining on the surface to the upper side of the ceiling. Therefore, the air stopped on the ground surface by the circulation fan 26 is moved to the upper side, contacts the heating pad 32 provided in the wind direction diffusing portion 37, and is discharged to the outer peripheral side of the cylindrical main body portion 20. Further, a part of the air flowing into the cylindrical main body 20 is discharged to the outer peripheral side, and a part of the air moves so as to flow into the moisture removing part 50 provided with the cooling pad 34 of the semiconductor element 30 for dehumidification. Is done. The air moved to the dehumidifying piece 40 on the upper side of the cooling pad 34 comes into contact with the damp air on the cold surface, and the water vapor is liquefied to form water droplets on the dehumidifying piece 40, so that the dehumidifying action is performed. . In this way, moisture in the dehumidified air generated in the dehumidifying piece 40 falls to the lower side of the moisture removing unit 50 and is discharged through the water drain port 52.

  As described above, the air circulation and dehumidification device of the present invention used in the summer is different from the winter in that the positions of the upper and lower portions of the cylindrical main body 20 change so that the part where the exhausted wind always hits first is the heat. The water drain port 52 of the moisture removing unit 50 may be positioned on the lower side at all times. As described above, according to the present invention, when moisture is removed while forcibly circulating the air located at the upper and lower sides inside the house in winter or summer, the humidity in the air in the house is lowered and the temperature distribution is uniform. Therefore, there is an effect that it is possible to provide an optimum state that matches the growth conditions of the crop.

  In order to lower the temperature by transferring heat generated from the heating pad 32 more quickly and effectively by the heating coil piece 31 as shown in FIG. If 55 is installed on the heating coil piece 31 in a straight line on a part side or formed in a donut shape as shown in FIG. The temperature can be lowered by more effectively diffusing. The heating pipe 55 is characterized in that a commercially available heating pipe 55 is filled with a heat transfer medium, and when heat is transmitted, it is instantaneously transmitted to the tip of the heating pipe 55 instantaneously. Can be used to quickly cool the heat due to the diffusion of temperature. Thus, the heat generated from the heating pad 32 can be quickly cooled using the heating pipe 55.

  Although the air circulation and dehumidification apparatus of the present invention has been described above limited to a house, the present invention is not limited to this and can be used in factories, general households, and the like.
