Description

  The present invention relates to a shutter with an insect net of a house.

  Recently, crops such as vegetables, leaf vegetables, fruits, flowers, etc. that are pesticide-free are useful. In addition, this kind of pesticide-free cultivation (including pesticide reduction) is indispensable when considering the general viewpoint and / or the global environment in consideration of the health of people, recovery of diseases, or agriculture in Japan. is there. From this point of view, cultivation methods using insect repellent nets are becoming mainstream in house cultivation. However, there is no consideration (ingenuity) regarding securing of the intake amount of outside air, temperature / humidity management, or reduction of the cultivation area (land area) of the house, and this is an obstacle to the spread of houses with insect repellent nets. it is conceivable that.

  The mesh size has a close relationship with securing the amount of outside air sucked in, temperature / humidity management, crop growth, securing the net covering area, and the like. For example, when the mesh of the net is about 1.0 mm, even if the normal net structure and / or mounting structure is adopted, the intake amount of the outside air can be secured or the temperature and humidity management can be optimized. Then, small insects invade and cause damage, which is undesirable. In addition, when the mesh size of the net is about 0.1 mm to 0.6 mm, it is possible to prevent the entry of small insects entering from the mesh size when it is assumed that a normal net structure and / or mounting structure is adopted (current situation) Then, it is thought that the invasion of small insects can be prevented, and about 100% of food damage can be prevented). However, it is not possible to ensure the amount of outside air sucked in or to optimize the temperature and humidity management (generally, in July to August, the temperature is approximately 2 ° C. to 5 ° C. and / or compared with the outside air. There is a real problem that a relative humidity increase of about 2% to 3% is conceivable. Furthermore, there is a problem of poor growth of crops, and the improvement is desired. Incidentally, the adverse effects due to the temperature rise of about 2 ° C. to 5 ° C. are likely to occur usually at high temperatures such as 25 to 30 ° C.

  In addition, if the mesh size of this net is approximately 0.1 mm to 0.6 mm and it is assumed that the intake amount of the outside air is ensured or the temperature / humidity management is optimized, the stretched area of the net is increased. This can be achieved. However, securing the net covering area (large or small) directly affects the size of the cultivated area of the house. For example, an increase in the net covering area may result in a state of covering the ridges and / or crops of the house, resulting in a decrease in yield, and a hindrance to the movement of people and equipment moving near the inner wall of the house. Can be considered.

  There are several inventions and ideas of the combination of insect repellent nets and ventilation fans, but there are some references related to the present invention. Document (1) is a “simultaneous suction / exhaust type exhaust fan” disclosed in Japanese Utility Model Publication No. 62-122239, in which the suction port formed under the gallery on the suction side is closed with an insect net (insect net). The purpose is to prevent the invasion of insects from this gallery. However, this device has not been improved with respect to the problem of meshing, ensuring the amount of outside air sucked in, or optimizing the temperature and humidity management. There are many problems to adopt. Reference (2) is “Shutter for window with insect repellent net” disclosed in Japanese Patent Application Laid-Open No. 7-208042, which has a structure in which a screen for insects is attached to the door surface of a roll-up shutter. Is intended. However, the same problem as the above-mentioned document (1) remains.

FIG. 5-2 is a plan view of FIG. 5-1, FIG. 6-1 is a side view showing a third example of the insect-proof net attached to the shutter, and FIG. 6-2 is a plan view of FIG. 6-1, and FIG. 7 shows a fourth example of the insect-proof net attached to the shutter. FIG. 8-1 is a side view, FIG. 8-1 is a schematic diagram of a first example showing the relationship between a shutter with an insect net and a crop of a house and / or crop, and FIG. 8-2 is a shutter with an insect net and a crop of a house and / or Or it is the reduced scale schematic diagram of the 2nd example which showed the relationship with a crop.

  Reference numeral 1 denotes a house (greenhouse) such as a vinyl house or a glass house, and a shutter is provided on one side 100 of the house 1 in the longitudinal direction 1a (one example is not limited and includes one side such as a ceiling surface, a side surface, and the like). 2 is attached (provided). As shown in FIG. 2, the shutter 2 includes a shutter frame 200, a plurality of shutter plates 201 (referred to as shutter plates 201) movably provided on the shutter frame 200, and the shutter plates 201 ( The interlocking plate 202 interlocks with the shutter plate 201, the mounting means 203 such as vinyl provided around the shutter frame 200, and the driving means 204 provided as necessary. Accordingly, each shutter plate 201 is opened and closed by wind pressure or driving means 204. When the shutter plate 201 is configured to be opened and closed by wind pressure, the air in the house 1 is driven by driving the outside air suction means or the stirring means such as the ventilation fan 3 provided in the house 1 or the stirring fan 4 provided with the impeller. (Inside air) is exhausted from the exhaust port 1c, and the shutter plate 201 is opened. When the shutter plate 201 is opened, air outside the house 1 is sucked into the house 1 and the shutter plate 201 is opened substantially simultaneously by the interlocking plate 202, for example. That is, the movement of the interlocking plate 202 causes the shutter plate 201 to move substantially simultaneously. When the outside air suction means or the stirring means such as the ventilation fan 3 or the stirring fan 4 provided in the house 1 stops driving, the shutter plate 201 is closed and the exhaust is stopped from the inside air exhaust port 1c. The shutter plate 201 is closed almost simultaneously by the interlocking plate 202. Further, in this example, at the time of stopping, due to a slight gap formed between the shutter plate 201 overlap and / or a slight gap formed between the inner periphery of the shutter frame body 200 and both ends of the shutter plate 201, etc. Invading insects can be caught by an insect net 5 described later. Then, considering that the gap is generated when there is a wind and the movement of insects is likely to be active when there is a wind, the capture by the insect net 5 is considered to be extremely useful (other examples) The same applies to the ventilation fan 3, the stirring fan 4, etc.). Further, escape of insects (not shown) working in the house 1 can be prevented (the same applies to other examples).

  The attachment means 203 is a member for attaching a wall material such as vinyl constituting the wall surface 1b of the one side 100 of the house 1, and this attachment means 203 is installed on the surface (outside side) of the shutter frame 200. The mounting frame 203a having a substantially flat U-shaped cross section and a spring pressing wire 203b fitted to the mounting frame 203a are attached by press-fitting the holding wire 203b into the mounting frame 203a, or It is a structure that can be removed by detachment. Therefore, there are features such that the attachment (detachment) can be facilitated and the vinyl or the like can be attached to the shutter 2 in an airtight state. In the case where the shutter plate 201 is configured to be opened and closed by the driving unit 204, the shutter plate 201 is moved substantially simultaneously by the movement of the interlocking plate 202 by the driving unit 204 and the link and / or cam mechanism. The action and / or driving of the outside air suction means or the stirring means such as the movable and / or ventilating fan 3 of the shutter plate 201 or the stirring fan 4 provided with the impeller are substantially the same. Although not shown, the opening direction of the shutter plate 201 is set to either the inside or outside of the house 1 depending on the selection of the suction method and / or the exhaust method.

  5 is an insect repellent net, and this insect repellent net 5 is constructed by using a pole 500 or a frame material standing on the house 1 (the insect repellent net 5 may be separated from the ground or may be in close contact with the ground) The suction side 3a (attachment side) is detachably provided on attachment means 203-1 provided on the back surface (inward side) of the shutter frame 200. And this attachment means 203-1 is also used as the attachment means 203 for vinyl attachment which constitutes the wall surface 1b of the one side 100 of the house 1, effective utilization of parts, simplification of the structure, and attachment / detachment. In addition, the mounting means 203 can be used effectively, the mounting loss can be reduced, the airtightness can be secured, and the insect-proofing effect can be achieved. In addition, although not shown, it is also possible to attach the ceiling of the house 1 and / or the beam material and the suspension means. The insect net 5 employs a structure that secures a stretched area A in order to avoid a decrease in the amount of air sucked due to meshing. An example of the basic configuration of the structure that secures the stretched area A is shown in FIGS. 4-1 and 4-2. 4-1 and the like are a plurality of poles 500 erected from the ground of the house 1, and a substantially square insect-proof net 5 is stretched, and the air flow is about 0.1 mm to 0.6 mm. In order to avoid a decrease in the amount of suction, a stretched area A is secured. In addition, although not shown in figure, the insect taking-out port which can be opened and closed is provided. In addition, the insect net 5 and the pole 500 are preferably configured so that the shape of the insect net 5 can be ensured by a metal fitting method or an insertion method, but if necessary, the shape can be changed by a band method, a button method, a hook-and-loop fastener method, or the like. Configuration is also possible. Each of these examples is characterized in that the intake air can be substantially equalized and that the same function as a conventional shutter (not shown) can be exhibited.

  Next, another example of the structure for securing the tension area A is shown in FIGS. FIG. 5A shows a plurality of poles 500 erected from the ground of the house 1 and has a substantially convex shape in side view with the suction side 5a being a narrow space and the discharge side 5b being a wide space. Secure the tension area A. Further, the insect net 5 and / or the end thereof does not cover the ridge 6 in the house 1 and avoids reaching the vicinity of the crop 7, for example, avoiding a decrease in the cultivation area, 7 is intended to further increase the quality and to increase the yield, or to secure a working environment (moving, facilitating the transfer and transportation of equipment). And in FIG. 5-2, the space of the up-down direction of the house 1 is used effectively, it becomes the substantially convex shape which stood up in the side view which made the suction side 5a a narrow space, and made the discharge side 5b a wide space, and the insect-proof net 5 The tensioning area A is secured. Others are the same as those in FIG. FIGS. 6A and 6B are substantially in the shape of a suction duct when viewed from the front, and ensure a stretched area A of the insect-proof net 5. This substantially suction duct shape can ensure a smooth wind flow by using the inclined widened portion. The characteristics and effects of the other configurations are the same as those in the above-described examples of FIGS. Further, FIG. 7 has a substantially trapezoidal shape when viewed from the side, and secures a stretched area A of the insect net 5. The characteristics and effects of the configuration are in accordance with the above-described examples. As a result of the experiment, it was found that the tension area A was effective even with the mesh size (0.4 mm) of the insect net 5 with little pressure loss. In the figure, reference numeral 203-1 denotes attachment means for attaching the insect net 5 in an airtight state, and this attachment means 203-1 is an attachment frame body having a substantially flat U-shaped cross section provided on the back surface (inward side) of the shutter frame body 200. 203a-1 and a spring holding wire 203b-1 fitted to the mounting frame 203a-1. The usage method is the same as that of the attachment means 203. These attachment means 203, 203-1 are merely examples, and other attachment methods and / or devices are possible. Also, the use of the attachment means 203-1 and the attachment means 203 is advantageous in that the number of parts can be omitted, management can be facilitated, attachment (detachment) can be simplified, cost can be reduced, and the like.

  In addition, the insect net 5 can be changed to a cold protection sheet, and it is possible to achieve cold countermeasures in winter and the like, as well as heat insulation, sound insulation, crime prevention effects, and the like.

  The shutter 2 and / or the insect net 5 are attached to a predetermined height of the wall surface 1b of the house 1 depending on the type of the crop 7 and / or conditions such as cultivation / climate. The mounting position and the shape and / or size of the insect net 5 have a correlation.
