[0009] Hereinafter, an indoor positive pressure smart farm facility house according to embodiments of the present invention will be described with reference to the drawings.

[0010] FIG. 1 is a schematic diagram showing an indoor positive pressure smart farm facility house according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken in the vertical direction of a positive pressure generating unit constituting an indoor positive pressure smart farm facility house according to a first embodiment of the present invention.

[0011] Referring to FIGS. 1 and 2 together, the indoor positive pressure smart farm facility house (100) according to the present embodiment is an indoor positive pressure smart farm facility house (100) that cultivates crops in the indoor space while forming a positive pressure state indoors, and includes a crop cultivation house member (110), an air supply member (120), an air supply pipe (121), and a positive pressure forming unit (130).

[0012] In this embodiment, the indoor positive pressure smart farm facility house (100) further includes a filter member (160).

[0013] The above crop cultivation house member (110) has an indoor space isolated from the outside formed inside it, and the cultivation of the crop takes place in the indoor space. Examples of such a greenhouse may be a vinyl house in which steel pillars are erected and the outside of the steel pillars is covered with vinyl.

[0014] The above crop cultivation house member (110) includes a plurality of vertical column members (111) that are spaced apart and erected vertically on the ground, and a cover member (112) that surrounds the upper and outer sides of the vertical column members (111).

[0015] The above air supply member (120) supplies external air into the interior of the crop cultivation house member (110), and an air pump, etc., may be presented as an example.

[0016] The air supply pipe (121) is connected between the air supply member (120) and the crop cultivation house member (110) to move the external air supplied from the air supply member (120) into the interior of the crop cultivation house member (110).

[0017] At least a portion of the air supply pipe (121) is buried underground, and the external air flowing through the air supply pipe (121) can undergo heat exchange with the underground to receive geothermal heat and then flow into the interior of the crop cultivation house member (110).

[0018] Then, the external air flowing through the air supply pipe (121) receives geothermal heat from the ground and is introduced into the interior of the crop cultivation house member (110) with a relatively higher temperature compared to the ambient air, which is the external air before it is introduced into the air supply member (120).

[0019] Generally, the crop grown inside the crop cultivation house member (110) grows at a temperature relatively higher than the outside air. For example, when the outside air supplied to the air supply member (120) flows through the air supply pipe (121) buried underground at a temperature of 25°C, heat exchange occurs with the ground in the air supply pipe (121), causing the temperature to rise to 28°C. As it flows into the indoor space inside the crop cultivation house member (110) in such a state, the inside of the crop cultivation house member (110) can quickly reach the temperature required for the cultivation of the crop, thereby reducing the overall energy required for the management of the crop cultivation house member (110).

[0020] Drawing number 122 is an indoor air flow pipe that is installed in a location close to the ground in the indoor space of the crop cultivation house member (110) and is connected to the air supply pipe (121) to allow air to flow inside the crop cultivation house member (110).

[0021] The above indoor air flow pipe (122) is arranged to spread evenly inside the crop cultivation house member (110).

[0022] Drawing number 123 is an air injection nozzle (123) that protrudes vertically from the indoor air flow pipe (122) and sprays the external air flowing from the air flow pipe toward the internal space of the crop cultivation house member (110).

[0023] When the external air is injected from the air injection nozzle (123), it fills the interior of the crop cultivation house member (110), and the air filling the interior of the crop cultivation house member (110) at this time becomes the internal air described later.

[0024] Drawing number 115 is an indoor pressure sensing unit capable of detecting the indoor pressure of the crop cultivation house member (110) in real time.

[0025] Although not shown in this embodiment, an indoor condition sensor, such as a carbon dioxide concentration sensor, a temperature sensor, and a humidity sensor, capable of detecting the internal condition of the crop cultivation house member (110), may be additionally installed inside the crop cultivation house member (110).

[0026] The above positive pressure forming unit (130) is installed in the crop cultivation house member (110) to form positive pressure inside the crop cultivation house member (110) so that the indoor pressure of the crop cultivation house member (110) can be relatively higher than the external pressure of the crop cultivation house member (110) by a certain amount.

[0027] When positive pressure is formed in the indoor space, which is the internal space of the crop cultivation house member (110), by the above-mentioned positive pressure forming unit (130), the carbon dioxide concentration, humidity, and temperature inside the crop cultivation house member (110) can be easily controlled.

[0028] The above positive pressure forming unit (130) may be composed of a plurality of units and may be coupled to the outer part (at least one of the side wall and the upper part) of the crop cultivation house member (110). In this embodiment, as shown in FIG. 1, a plurality of units are spaced apart and installed on the upper part of the crop cultivation house member (110).

[0029] The above positive pressure forming unit (130) includes a positive pressure forming body (131), an air inlet hole (132), an air outlet hole (133), an air communication hole (134), an inlet hole opening / closing body (135), a communication hole opening / closing body (136), an inlet hole opening / closing body movement limiting body (137), a communication hole opening / closing body discharge prevention body (138), an opening / closing body movement plate (139), a positive pressure forming cylinder (140), and a positive pressure forming piston (141).

[0030] The above positive pressure forming body (131) is installed on the upper part of the crop cultivation house member (110) and forms the outer frame of the above positive pressure forming unit (130).

[0031] The above air inlet hole (132) allows at least a portion of the indoor air that was inside the crop cultivation house member (110) to flow into the interior of the positive pressure forming body (131).

[0032] The air discharge hole (133) discharges the indoor air introduced through the air inlet hole (132) to the outside of the positive pressure forming body (131).

[0033] One end of the air communication hole (134) is connected to the air inlet hole (132), and the other end is connected to the air outlet hole (133), thereby connecting the air inlet hole (132) and the air outlet hole (133).

[0034] The air inlet hole (132), the air communication hole (134), and the air discharge hole (133) are connected to each other and penetrate the positive pressure forming body (131), and the indoor air introduced from the crop cultivation house member (110) into the air inlet hole (132) can be discharged to the outside of the positive pressure forming body (131) through the air communication hole (134) and the air discharge hole (133).

[0035] The above-mentioned inlet hole opening / closing body (135) is movably positioned between the air inlet hole (132) and one end portion of the air communication hole (134) (the end portion adjacent to the air inlet hole (132)) and opens / closes the air inlet hole (132), and is formed in the shape of a ball.

[0036] The above-mentioned communication hole opening / closing body (136) is movably positioned between the air discharge hole (133) and the other end of the air communication hole (134) (the end adjacent to the air discharge hole (133)) and opens / closes the air communication hole (134), and is formed in a ball shape.

[0037] The above-mentioned inlet hole opening / closing body (135) can open / close the air inlet hole (132) by moving a predetermined distance between the air inlet hole (132) and the air communication hole (134) along the length direction of the air inlet hole (132) and coming into contact with the end portion of the air inlet hole (132) or being spaced apart from the end portion of the air inlet hole (132).

[0038] The above-mentioned inlet hole opening / closing body movement limiter (137) is positioned at one end of the air communication hole (134), which is a part adjacent to the air inlet hole (132), and limits the movement range of the inlet hole opening / closing body (135) so as to prevent the air communication hole (134) from being blocked by the inlet hole opening / closing body (135).

[0039] In the central part of the inlet hole opening / closing body movement limiter (137), a through hole having a diameter that is relatively smaller than that of the inlet hole opening / closing body (135) is formed, so that the indoor air can flow from the air inlet hole (132) toward the air communication hole (134), but the movement of the inlet hole opening / closing body (135) toward the air communication hole (134) to block the entrance portion of the air communication hole (134) is restricted.

[0040] The above communication hole opening / closing body discharge prevention body (138) is positioned at the end of the air discharge hole (133) to prevent external discharge of the communication hole opening / closing body (136).

[0041] In the central part of the above-mentioned communication hole opening / closing body discharge prevention body (138), a through hole having a diameter that is relatively smaller than that of the above-mentioned communication hole opening / closing body (136) is formed, so that the indoor air can flow to the outside through the air communication hole (134) and the air discharge hole (133), but the discharge hole opening / closing body can be prevented from being discharged to the outside of the above-mentioned positive pressure forming body (131).

[0042] The above opening / closing body moving plate (139) is arranged parallel to the air communication hole (134) in the internal space of the positive pressure forming body (131), and is formed in the shape of a disc made of an elastically deformable material such as rubber, so as to be able to move the inlet hole opening / closing body (135) or the communication hole opening / closing body (136), and a diaphragm, etc., may be presented as an example.

[0043] As shown in FIG. 2, the above opening / closing movable plate (139) is elastically deformed in a direction perpendicular to the longitudinal direction of the air communication hole (134), that is, in a direction closer to or further away from the air communication hole (134).

[0044] The above positive pressure forming cylinder (140) is installed in the internal space of the above positive pressure forming body (131).

[0045] One end of the positive pressure forming piston (141) is connected to the opening / closing movable plate (139), and the other end is connected to the positive pressure forming cylinder (140) so that it can be inserted into the interior of the positive pressure forming cylinder (140) or protrude from the positive pressure forming cylinder (140), thereby elastically deforming the opening / closing movable plate (139).

[0046] When the edge portion of the opening / closing movable plate (139) is fixed inside the positive pressure forming body (131) and the positive pressure forming piston (141) is inserted into the positive pressure forming cylinder (140) by the operation of the positive pressure forming cylinder (140), the portion of the opening / closing movable plate (139) facing the air communication hole (134) is elastically deformed into a concave shape while moving relatively away from the air communication hole (134). Due to the elastic deformation of the opening / closing movable plate (139) into a concave shape, the inlet hole opening / closing body (135) is separated from the air inlet hole (132) and moved toward the inlet hole opening / closing body movement limiter (137), thereby allowing the indoor air of the crop cultivation house member (110) to flow toward the air communication hole (134) through the air inlet hole (132).

[0047] At this time, the above-mentioned communication hole opening / closing body (136) comes into contact with the end portion of the above-mentioned air communication hole (134) and blocks the above-mentioned air communication hole (134).

[0048] Then, when the positive pressure forming piston (141) protrudes outside the positive pressure forming cylinder (140) by the operation of the positive pressure forming cylinder (140), the part of the opening / closing body moving plate (139) facing the air communication hole (134) becomes elastically deformed into a convex shape while being relatively close to the air communication hole (134), and due to the elastic deformation of the opening / closing body moving plate (139) into a convex shape, the communication hole opening / closing body (136) is separated from the air communication hole (134) and moved toward the communication hole opening / closing body discharge prevention body (138), thereby allowing the indoor air flowing in the air communication hole (134) to be discharged to the outside through the air discharge hole (133).

[0049] At this time, the inlet hole opening / closing body (135) comes into contact with the end portion of the air inlet hole (132) and blocks the air inlet hole (132).

[0050] The operation of the above positive pressure forming unit (130) is controlled by a house control member (116) installed inside or outside the crop cultivation house member (110).

[0051] In detail, the house control member (116) controls the operation of the positive pressure generating unit (130). The house control member (116) compares the house indoor pressure detected by the indoor pressure sensing unit (115) with a preset indoor pressure within the house control member (116). If it is determined that the house indoor pressure is relatively smaller or equal to the preset indoor pressure, the house control member (116) deactivates the positive pressure generating unit (130). At this time, the positive pressure generating piston (141) is maintained in a protruding state from the positive pressure generating cylinder (140), thereby blocking the inflow of the internal air into the air inlet hole (132).

[0052] Then, when the house control member (116) determines that the indoor pressure of the house has exceeded the set indoor pressure, the house control member (116) commands the positive pressure forming unit (130), more precisely the positive pressure forming cylinder (140), so that the insertion and protrusion of the positive pressure forming piston (141) of the positive pressure forming cylinder (140) are repeatedly performed, and accordingly, the internal air of the crop cultivation house member (110) can be introduced into the air inlet hole (132) and then discharged to the outside through the air communication hole (134) and the air discharge hole (133).

[0053] In this embodiment, the house control member (116) controls the operation of the air supply member (120) and the filter member (160) in addition to the positive pressure forming unit (130).

[0054] The filter member (160) is installed at the front end of the air supply member (120) to filter the external air flowing into the air supply member (120), and includes a foreign matter filter section (161) that removes foreign substances from the external air and an antiviral filter section (162) that removes viruses from the external air.

[0055] As the filter member (160) is formed, the external air can be introduced into the interior of the air supply member (120) after foreign substances and viruses are removed, and accordingly, growth diseases of the crop grown inside the crop cultivation house member (110) can be prevented in advance.

[0056] Hereinafter, the operation of the indoor positive pressure smart farm facility house (100) according to the present embodiment will be briefly explained with reference to the drawings.

[0057] First, the outside air outside the crop cultivation house member (110) flows into the filter member (160), and foreign substances are removed from the foreign substance filter section, and then the virus is removed from the antiviral filter section.

[0058] The external air passing through the filter member (160) is introduced into the air supply member (120) and then flows into the interior of the crop cultivation house member (110) through the air supply pipe (121).

[0059] At this time, as at least a portion of the air supply pipe (121) is buried in the ground, the external air flowing inside the air supply pipe (121) is injected into the interior of the crop cultivation house member (110) after heat exchange with the ground, so that the interior of the crop cultivation house member (110) can maintain a temperature relatively higher than the external ambient temperature.

[0060] The house control member (116) compares the set indoor pressure with the actual indoor pressure, and if it is determined that the actual indoor pressure is relatively smaller or equal to the set indoor pressure, the house control member (116) deactivates the positive pressure generating unit (130). At this time, the positive pressure generating piston (141) constituting the positive pressure generating unit (130) remains in a state protruding from the positive pressure generating cylinder (140).

[0061] Then, when the actual indoor pressure is determined by the house control member (116) to exceed the set indoor pressure, the house control member (116) commands the positive pressure forming unit (130) to repeatedly insert and extend the positive pressure forming piston (141) to discharge the internal air to the outside.

[0062] As described above, the indoor positive pressure smart farm facility house (100) includes the crop cultivation house member (110), the air supply member (120), the air supply pipe (121), and the positive pressure forming unit (130). As a result, positive pressure is formed inside the crop cultivation house member (110), thereby blocking the arbitrary inflow of the outside air outside the crop cultivation house member (110). Accordingly, the penetration of foreign substances and viruses contained in the outside air is prevented, allowing the crop to grow safely without disease.

[0063] Hereinafter, an indoor positive pressure smart farm facility house according to other embodiments of the present invention will be described with reference to the drawings.

[0064] In carrying out this explanation, any descriptions that overlap with those already described in the first embodiment of the present invention described above will be replaced and omitted here.

[0065] FIG. 3 is a schematic diagram showing the indoor positive pressure smart farm facility house according to the second embodiment of the present invention.

[0066] Referring to FIG. 3, in this embodiment, the indoor positive pressure smart farm facility house further includes a crop cultivation house member (210), an air supply member (220), an air supply pipe (221), a positive pressure forming unit (230), and a geothermal supply member (225).

[0067] The above geothermal supply member (225) is buried underground and heat exchange is performed with the underground, thereby supplying geothermal heat to the external air supplied from the air supply member to the crop cultivation house member.

[0068] The above geothermal supply member (225) includes a geothermal exchange section (227), an air heat exchange section (226), a geothermal supply pipe (228), and a geothermal recovery pipe (229).

[0069] The above-mentioned geothermal exchange unit (227) is buried underground and heat exchange with the underground, and is formed in a U-shape in the underground.

[0070] The above air heat exchanger (226) is a unit through which the air supply pipe passes and heat exchange is performed with the air supply pipe.

[0071] The above geothermal supply pipe (228) is connected between the geothermal exchange unit (227) and the air heat exchange unit (226) and supplies the geothermal heat from the ground to the air heat exchange unit (226) through a circulating fluid flowing inside it.

[0072] The above geothermal recovery pipe (229) is connected between the geothermal exchange unit (227) and the air heat exchange unit (226) separately from the above geothermal supply pipe (228), so that geothermal heat passing through the air heat exchange unit (226) is recovered to the geothermal exchange unit (227).

[0073] The geothermal heat of the above geothermal exchange unit (227) flows to the air heat exchange unit (226) through the circulating fluid flowing through the geothermal supply pipe (228), and is then transferred to the air supply pipe passing through the air heat exchange unit (226), so that the external air flowing inside the air supply pipe can be raised to a relatively higher temperature by a certain amount.

[0074] Although not shown in this embodiment, a thermal storage tank, such as a storage tank capable of storing the geothermal heat delivered through the geothermal supply pipe (228), may be additionally installed between the geothermal supply pipe (228) and the air heat exchanger (226).

[0075] Hereinafter, an indoor positive pressure smart farm facility house according to the third embodiment will be described with reference to the drawings.

[0076] In carrying out this explanation, any descriptions that overlap with those already described in the first and second embodiments of the present invention described above will be replaced and omitted here.

[0077] FIG. 4 is a cross-sectional view taken in the vertical direction of a positive pressure generating unit constituting an indoor positive pressure smart farm facility house according to the third embodiment of the present invention, and FIG. 5 is an enlarged view of a foreign matter discharge part constituting the positive pressure generating unit of FIG. 4.

[0078] Referring to FIGS. 4 and 5, in this embodiment, a positive pressure generating unit (330) constituting an indoor positive pressure smart farm facility house includes a positive pressure generating body (331), an air inlet hole (332), an air outlet hole (333), an air communication hole (334), an inlet hole opening / closing body (335), a communication hole opening / closing body (336), an inlet hole opening / closing body movement limiting body (337), a communication hole opening / closing body discharge prevention body (338), an opening / closing body movement plate (339), a positive pressure generating cylinder (340), a positive pressure generating piston (341), a positive pressure generating extension piston (342), an inlet hole side sealing part (350), and a communication hole side sealing part (355).

[0079] The above positive pressure forming body (331) is coupled to the crop cultivation house member and forms the outer frame of the above positive pressure forming unit (330).

[0080] The above air inlet hole (332) allows indoor air from inside the crop cultivation house member to be introduced.

[0081] The air discharge hole (333) discharges the indoor air introduced through the air inlet hole (332) to the outside.

[0082] The above air communication hole (334) connects the air inlet hole (332) and the air outlet hole (333).

[0083] The above-mentioned inlet hole opening / closing body (335) is movably positioned between the air inlet hole (332) and the air communication hole (334) to open and close the air inlet hole (332).

[0084] The above communication hole opening / closing body (336) is movably positioned between the air discharge hole (333) and the air communication hole (334) to open and close the air communication hole (334).

[0085] The above-mentioned inlet hole opening / closing body movement limiter (337) is positioned at the end of the air communication hole (334) to limit the movement range of the inlet hole opening / closing body (335) so as to prevent the air communication hole (334) from being blocked by the inlet hole opening / closing body (335).

[0086] The above communication hole opening / closing body discharge prevention body (338) is positioned at the end of the air discharge hole (333) to prevent external discharge of the communication hole opening / closing body (336).

[0087] The above opening / closing body moving plate (339) is positioned parallel to the air communication hole (334) inside the positive pressure forming body (331) and is made of an elastically deformable material so as to be able to move the inlet hole opening / closing body (335) and the communication hole opening / closing body (336), respectively.

[0088] The above positive pressure forming cylinder (340) is installed inside the above positive pressure forming body (331).

[0089] One end of the above positive pressure forming piston (341) is connected to the opening / closing movable plate (339) and the other end is connected to the positive pressure forming cylinder (340), thereby elastically deforming the opening / closing movable plate (339) by being inserted into the positive pressure forming cylinder (340) or protruding from the positive pressure forming cylinder (340).

[0090] The above positive pressure forming extension piston (342) is formed in a shape that extends from the positive pressure forming piston (341), penetrates the positive pressure forming cylinder (340), and then protrudes outward, and moves back and forth along the longitudinal direction of the positive pressure forming piston (341) together with the positive pressure forming piston (341) by the operation of the positive pressure forming cylinder (340).

[0091] When the positive pressure forming piston (341) is protruded from the positive pressure forming cylinder (340) by the operation of the positive pressure forming cylinder (340), the positive pressure forming extension piston (342) is inserted into the positive pressure forming cylinder (340), and when the positive pressure forming cylinder (340) is inserted into the positive pressure forming piston (341) by the operation of the positive pressure forming cylinder (340), the positive pressure forming extension piston (342) is protruded from the positive pressure forming cylinder (340).

[0092] The above-mentioned inlet hole side sealing part (350) pushes the inlet hole opening / closing body (335) so that the air inlet hole (332) is sealed by the inlet hole opening / closing body (335) when the inlet hole opening / closing body (335) blocks the air inlet hole (332).

[0093] The above-mentioned inlet hole side sealing part (350) is connected to a first piston movement space (343), which is a space within the internal space of the positive pressure forming body (331) where the positive pressure forming piston (341) moves, and has an inlet hole side flow path (351) through which at least a portion of the air in the first piston movement space (343) flows, an inlet hole side branch flow path (352) branched from the inlet hole side flow path (351), and connects the inlet hole side flow path (351) with the air communication hole (334) and the inlet hole side branch flow path (352) with the air communication hole (334), respectively, thereby injecting the air moved from the first piston movement space (343) to the inlet hole side flow path (352) and the inlet hole side branch flow path (352), respectively, toward the inlet hole opening / closing body (335) located in the air inlet hole (332). It includes a spray tube (353).

[0094] Among the above inlet hole side injection pipes (353), the portion communicating from the inlet hole side flow pipe (351) to the air communication hole (334) and the portion communicating from the inlet hole side branch flow pipe (352) to the air communication hole (334) are formed to face each other with respect to the air communication hole (334). For example, the portion communicating from the inlet hole side flow pipe (351) to the air communication hole (334) is located on one side of the air communication hole (334), and the portion communicating from the inlet hole side branch flow pipe (352) to the air communication hole (334) is located on the other side of the air communication hole (334), so that air is injected from both sides of the inlet hole opening / closing body (335).

[0095] When the above-described inlet hole side sealing part (350) is configured as described above, the opening / closing body moving plate (339) is elastically deformed into a convex shape (when the positive pressure forming piston (341) and the positive pressure forming extension piston (342) are advanced to be close to the air communication hole (334), and when the inlet hole opening / closing body (335) blocks the air inlet hole (332), at least some of the air in the first piston moving space (343) flows into the inlet hole side flow path (351) and the inlet hole side branch flow path (352), and then is injected from the inlet hole side injection pipe (353) to push the upper part of the inlet hole opening / closing body (335) that is blocking the air inlet hole (332), thereby sealing the air inlet hole (332) by the inlet hole opening / closing body (335).

[0096] The above-mentioned communication hole side sealing part (355) pushes the communication hole opening / closing body (336) so that when the communication hole opening / closing body (336) blocks the air communication hole (334), air is injected onto the upper part of the communication hole opening / closing body (336) to press the communication hole opening / closing body (336), thereby ensuring that the air communication hole (334) is sealed by the communication hole opening / closing body (336).

[0097] The above communication hole side sealing part (355) is connected to a second piston movement space (344), which is a space within the interior of the positive pressure forming body (331) where the positive pressure forming extension piston (342) moves, and has a communication hole side flow path (356) through which at least a portion of the air in the second piston movement space (344) flows, a communication hole side branch flow path (357) branched from the communication hole side flow path (356), and a communication hole side flow path (356) and the air discharge hole (333), and a communication hole side branch flow path (357) and the air discharge hole (333) are respectively connected to each other so that the air moved from the second piston movement space (344) to the communication hole side flow path (356) and the communication hole side branch flow path (357), respectively, is injected toward the communication hole opening / closing body located at the air discharge hole (333). It includes a spray tube (358).

[0098] When the positive pressure forming piston (341) and the positive pressure forming extension piston (342) are moved forward by the operation of the positive pressure forming cylinder (340), the first piston movement space (343) is compressed, and at least some of the air in the first piston movement space (343) flows into the inlet hole side flow path (351) and the inlet hole side branch flow path (352), respectively, and then is injected from the inlet hole side injection pipe (353).

[0099] Additionally, when the positive pressure forming piston (341) and the positive pressure forming extension piston (342) are moved backward by the operation of the positive pressure forming cylinder (340), the second piston movement space (344) is compressed, and at least some of the air in the second piston movement space (344) flows into the communication hole side flow path (356) and the communication hole side branch flow path (357), respectively, and then is injected from the air discharge hole (333).

[0100] Among the above-mentioned injection pipes (358) on the communication hole side, the portion communicating from the communication hole side flow path (356) to the air discharge hole (333) and the portion communicating from the communication hole side branch flow path (357) to the air discharge hole (333) are formed to face each other with respect to the air discharge hole (333). For example, the portion communicating from the communication hole side flow path (356) to the air discharge hole (333) is located on one side of the air discharge hole (333), and the portion communicating from the communication hole side branch flow path (357) to the air discharge hole (333) is located on the other side of the air discharge hole (333), so that air is injected from both sides of the communication hole opening / closing body (336).

[0101] When the above-mentioned air communication hole side sealing part (355) is configured as above, the above-mentioned opening / closing body moving plate (339) is elastically deformed into a concave shape (when the above-mentioned positive pressure forming piston (341) and the above-mentioned positive pressure forming extension piston (342) move backward away from the above-mentioned air communication hole (334), and when the above-mentioned air communication hole opening / closing body (336) blocks the above-mentioned air communication hole (334), at least some of the air in the above-mentioned second piston moving space (344) is injected from the above-mentioned air injection pipe (358) through the above-mentioned air communication hole side flow pipe (356) and the above-mentioned air communication hole side branch flow pipe (357), thereby pushing the upper side of the above-mentioned air communication hole opening / closing body (336) that is blocking the above-mentioned air communication hole (334), thereby sealing the above-mentioned air communication hole (334) by the above-mentioned air communication hole opening / closing body (336).

[0102] Meanwhile, in this embodiment, the positive pressure forming unit (330) further includes a foreign substance discharge unit (360) installed inside the communication hole-side flow path (356) to discharge foreign substances that may enter from the outside of the positive pressure forming body (331) through the air discharge hole (333) and the communication hole-side flow path (356) to the outside.

[0103] The above foreign matter discharge section (360) comprises a fixed body (361) coupled to the inner wall surface of the communication hole-side flow path (356), a foreign matter discharge body (362) formed in the shape of a disc with a predetermined area and rotatably connected to the fixed body (361) using a rotational means such as a rotation shaft, an air flow hole (363) formed at a certain angle with respect to the longitudinal direction of the foreign matter discharge body (362) and penetrating the foreign matter discharge body (362) at a spaced interval, an air flow hole (363), and formed at a certain angle with respect to the longitudinal direction of the foreign matter discharge body (362), a foreign matter catch net (365) disposed at a certain distance forward from the foreign matter discharge body (362) and formed in a mesh shape to catch foreign matter flowing into the communication hole-side flow path (356), and penetrating from the communication hole-side flow path (356) to the outside of the positive pressure forming body (331) and the foreign matter caught in the foreign matter catch net (365) to the positive pressure forming It includes a foreign substance discharge hole (367) that discharges to the outside of the body (331), and a foreign substance separator (364) that protrudes by a predetermined length from the end of the surface of the foreign substance discharge body (362) facing the foreign substance discharge hole (367) and, when the foreign substance discharge body (362) is rotated, strikes the area around the entrance of the foreign substance discharge hole (367) to separate the foreign substance caught in the foreign substance catch net (365) from the foreign substance catch net (365).

[0104] Here, the rear of the foreign substance discharge body (362) is the part of the foreign substance discharge body (362) that is close to the second piston movement space (344) based on the direction shown in FIG. 5, and the front of the foreign substance discharge body (362) is the part of the foreign substance discharge body (362) that is close to the air discharge hole (333) based on the direction shown in FIG. 5.

[0105] When at least some of the air in the second piston moving space (344) flows toward the air discharge hole (333) through the communication hole side flow path (356), the foreign matter discharge hole (367) is connected to the communication hole side flow path (356), so that some of the air flowing in the communication hole side flow path (356) is discharged to the outside of the positive pressure forming body (331) through the foreign matter discharge hole (367).

[0106] The above foreign matter discharge body (362) is connected to one end of the above fixed body (361) and is erected in the vertical direction by its own weight to block the above communication hole side flow path (356). In such a state, when air outside the above positive pressure forming body (331) flows into the above communication hole side flow path (356) through the air discharge hole (333) for air filling of the above second piston movement space (344), if foreign matter is mixed and introduced together with the air outside the above positive pressure forming body (331), the introduced foreign matter is caught by the foreign matter catch net (365), and the external air that passes through the foreign matter catch net (365) flows into the above second piston movement space (344) and is received in the above second piston movement space (344).

[0107] Then, when at least some of the air in the second piston moving space (344) flows toward the air discharge hole (333) through the air passage pipe (356) to seal the air passage hole (334) by the air passage hole opening / closing body (336), the foreign matter discharge body (362) rotates clockwise by the wind power of the air flowing from the second piston moving space (344), and the foreign matter separator (364) strikes the inlet side periphery connected to the air passage pipe (356) in the foreign matter discharge hole (367), causing the foreign matter caught in the foreign matter catch net (365) to be separated from the foreign matter catch net (365), and the separated foreign matter is discharged to the outside through the foreign matter discharge hole (367) together with the air flowing from the second piston moving space (344) toward the foreign matter discharge hole (367).

[0108] The above foreign substance separator (364) is made of an elastic material such as rubber so that it can be elastically deformed when colliding with the periphery of the entrance side of the foreign substance discharge hole (367).

[0109] When configured as described above, the phenomenon of foreign matter being caught in the foreign matter catch net (365) and the phenomenon of the foreign matter caught in the foreign matter catch net (365) being discharged through the foreign matter discharge hole (367) occur automatically without any external force according to the flow direction of the air flowing in the communication hole side flow path (356), thereby preventing foreign matter from entering the second piston movement space (344) and allowing the foreign matter caught in the foreign matter catch net (365) to be separated and discharged to the outside, so that the foreign matter catch net (365) can be maintained in a clean state.

[0110] In this embodiment, the air flow hole (363) is formed to slope downward from the rear to the front, and an air diffusion space (366) is formed between the foreign matter discharge body (362) and the foreign matter catch net (365) at a predetermined distance.

[0111] Then, when at least some of the air in the second piston moving space (344) flows toward the air discharge hole (333) through the communication hole side flow path (356), it flows obliquely along the air flow hole (363) and then spreads in the air diffusion space (366), and the air spread in the air diffusion space (366) pushes the foreign matter catch net (365) as a whole, thereby ensuring that the foreign matter is separated evenly over the entire area of ​​the foreign matter catch net (365), and at the same time, damage to the foreign matter catch net (365) caused by the wind power of the air flowing from the second piston moving space (344) toward the air discharge hole (333) can be prevented.

[0112] The air in the second piston movement space (344) becomes compressed by the movement of the positive pressure forming extension piston (342). When air flows toward the air discharge hole (333) through the communication hole side flow path (356) in such a state, the foreign matter catch net (365) may be damaged by the wind force. However, as the air diffusion space (366) is formed, the foreign matter catch net (365) is pushed with the wind force relatively reduced, thereby separating the foreign matter caught in the foreign matter catch net (365) while preventing damage to the foreign matter catch net (365).

[0113] Although the present invention has been illustrated and described above with respect to specific embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims. However, it should be clearly stated that all such modifications and variations are included within the scope of the present invention. Industrial applicability
