According to the invention of claim 3, since the fan stops air blowing when the door of the doorway is open, the air that has entered the room from the outside by opening the door is prevented from being circulated into the room as much as possible. it can. For example, when the door separates the outdoor from the indoor, when the door is opened in the winter, cold outside air enters the room mainly from the lower side of the entrance (foot of the person entering and exiting). Here, if you are in the lower suction operation that sucks in air from the lower vent and blows out from the upper vent, cool air that has entered while the door is open is sucked in from the lower side of the door pocket next to the doorway It will be circulated in the room. In this regard, the present invention can prevent this by stopping the fan while the door is open. Also, if you are in the lower blowing operation that sucks in air from the upper vent and blows out from the lower vent, the cold air that has entered while the door is open is entrained with the air blown from the vent However, the inflow of cold air may be promoted, but the present invention can prevent this by stopping the fan while the door is open.

  The door pocket structure 10 is provided as a door pocket of a sliding door type door 1 that opens and closes an entrance 1A of a room R, and partitions a door accommodation space 2 that accommodates the door 1 when the door 1 moves to open the entrance 1A. The outdoor panel 11 and the indoor panel 20 are provided. The outdoor side panel 11 and the indoor side panel 20 are assembled to a frame 1C that supports the door 1 in a slidable manner. The door 1 can partition the room A and the room B when closed.

  The indoor side panel 20 is configured as a two-layer panel structure having an outer panel 21 and an inner panel 22 arranged in parallel with each other at an interval, and the vertical direction is provided between the outer panel 21 and the inner panel 22. A ventilation path 23 penetrating through is secured.

  A lower ventilation chamber 24 having a ventilation opening 24A that opens toward the room A is provided at the lower part of the indoor side panel 20, and a ventilation opening 25A that opens toward the room A is provided at the upper part of the indoor panel 20. The upper ventilation chamber 25 provided with is provided. The ventilation path 23 formed in the interior side panel 20 has an upper end communicating with the upper ventilation chamber 25 and a lower end communicating with the lower ventilation chamber 24.

  In addition, an electric fan (blower) 26 for forced ventilation is installed at the ventilation opening 25 </ b> A of the upper ventilation chamber 25. The fan 26 performs forced air blowing to blow indoor air sucked from one of the ventilation port 25 </ b> A of the upper ventilation chamber 25 and the ventilation port 24 </ b> A of the lower ventilation chamber 24 from the other through the ventilation path 23.

  The door pocket structure 10 of the present embodiment is operated by a lower suction operation. When the fan 26 is driven, air in the lower layer portion of the room A is sucked from the ventilation port 24A of the lower ventilation chamber 24 and the air is passed through the ventilation path 23. 1 is circulated upward as indicated by an arrow Y in FIG. 1 and blown out from the ventilation opening 25 </ b> A of the upper ventilation chamber 25. Therefore, a dust collecting filter 28 is attached to the ventilation opening 24 </ b> A of the lower ventilation chamber 24.

  In addition, temperature sensors 31 and 32 are provided at the upper and lower portions of the indoor panel 20, respectively. Further, the door pocket structure 10 includes control means (not shown) for driving and controlling the fan 26. This control means adjusts the amount of blown air by controlling the output of the fan 26 according to the detection values of the temperature sensors 31 and 32. The control means can also turn on / off the fan 26 in conjunction with the opening / closing operation of the door 1. This point will be described later.

Next, the operation will be described.
When the door pocket structure 10 is operated, the fan 26 is driven. Then, as shown in FIG. 6 (a), the air in the lower layer portion of the room A is sucked from the ventilation opening 24A of the lower ventilation chamber 24, and the air is circulated upward in the ventilation passage 23, so that the upper ventilation chamber Blow out from 25 vents 25A. Therefore, as shown by the arrows in FIG. 6A, the air near the floor and the air near the ceiling can be circulated efficiently.

  Moreover, since this door pocket structure 10 is installed as a door pocket which is an incidental facility of the sliding door type door 1, it does not get in the way, and it is not necessary to separately provide a fan for circulating air. Accordingly, it is possible to eliminate the problem of the blower overturning and the danger of human hands touching the rotating blades of the blower. Further, since the air is blown from the door pocket near the doorway, it is possible to eliminate the problem that a strong wind is blown locally to a specific location in the room.

  In addition, when the fan 26 is stopped, the heat insulation effect can be exerted by the air staying in the ventilation path 23, so that the transfer of heat inside and outside the room through the door pocket can be suppressed. At this time, if the ventilation openings 24A and 25A can be closed with a damper or the like, the air flow can be reliably blocked, so that a further heat insulating effect can be exhibited.

  Moreover, since this door pocket structure 10 is provided with temperature sensors 31 and 32 at the upper part and the lower part, the temperature difference between the upper part and the lower part detected by the upper temperature sensor 31 and the lower temperature sensor 32 by a control means (not shown). Accordingly, the amount of air blown by the fan 26 can be changed. For example, by controlling to increase the air flow when the temperature difference between the upper and lower parts is large and to decrease the air flow when the temperature difference is small, air circulation is promoted with an appropriate air flow according to the temperature difference. And can contribute to uniform temperature in the room.

  Further, if the fan 26 is blown in the opposite direction, it can be changed to the lower blowing operation as shown in FIG. That is, by reversing the blowing direction of the fan 26, the air in the upper layer part of the room A is sucked from the ventilation opening 25A of the upper ventilation chamber 25, and the air is circulated downward in the ventilation path 23, so that the lower side It can be made to blow out from the ventilation opening 24A of the ventilation chamber 24. Also in this case, the air near the ceiling and the air near the floor can be circulated efficiently.

Next, another embodiment will be described.
FIG. 7: is the front view seen from the outdoor side of the door pocket structure of 2nd Embodiment of this invention. In this 2nd Embodiment, when the outdoor side panel 11 is arrange | positioned toward the outdoors which receives sunlight, the solar cell panel 50 is arrange | positioned in at least one part of the outer surface of the outdoor side panel 11. FIG. By doing so, the power generated by the solar cell panel 50 can be used as at least a part of the driving power of the fan 26, and the energy saving effect can be improved. Further, if it is possible to cover all the driving power of the fan 26 with the power generated by the solar cell panel 50, the wiring work of the power supply system can be minimized.

  FIG. 8 is a side sectional view of a door pocket structure according to a third embodiment of the present invention. In the case where the outdoor panel 11 is arranged toward the outdoors receiving sunlight as in the third embodiment, and the outdoor panel 11 is configured by a transparent member that transmits sunlight, By providing a reflective surface 51 (for example, formed by attaching a reflective material) that reflects sunlight on the outer surface of the outer panel 21 of the inner panel 20, it is possible to reflect solar radiation, for example, in the summer, so the temperature of the room A The rise can be suppressed. The same effect can be obtained even if the reflecting surface 51 that reflects sunlight is provided on the outer surface of the outdoor panel 11.

  FIG. 9 is a sectional side view of a door pocket structure according to a fourth embodiment of the present invention. In the fourth embodiment, the outdoor panel 11 is arranged toward the outdoors receiving sunlight, and the outdoor panel 11 and the outer panel 21 of the indoor panel 20 are transparent members that transmit sunlight. When configured, the sunlight that has passed through the outdoor panel 11 and the outer panel 21 of the indoor panel 20 is reflected on the plate surface facing the ventilation path 23 of the inner panel 22 of the indoor panel 20. A reflective surface 51 (for example, formed by attaching a reflective material) for warming the air in the ventilation path 23 is provided. By doing so, the air in the ventilation path 23 can be warmed, for example, in winter, so that the air circulation effect by natural convection can be obtained even when the fan 26 is stopped.

  Next, another problem that occurs when the door pocket structure of the present invention is applied to the door pocket of the sliding door of the doorway leading to the outdoors will be described.

  When the door pocket structure of the present invention is applied as a door pocket that partitions the outdoor and indoor, as shown in FIGS. 10 to 12, when the door 1 of the doorway 1A is open, outside air enters the room from the outside. . Especially in the cold season such as winter, the cold outdoor air in the outdoor room B enters the indoor room A mainly through the lower side of the entrance / exit 1A (the feet of people entering and exiting).

  At that time, when the fan 26 is operating and the lower suction operation for sucking air from the ventilation port 24A (see FIG. 1) of the lower ventilation chamber 24 is performed, the cold outside air that has entered through the inlet / outlet 1A is shown in FIG. As shown in FIG. 11, the air is sucked from the lower side of the door pocket structure 10 located directly beside and circulated in the room.

  Therefore, as a countermeasure in such a case, a control means (not shown) controls the fan 26 to stop while the door 1 is opened. As described above, when the air blown by the fan 26 is stopped while the door 1 is opened, it is possible to prevent the air that has entered the room from the outside by opening the door 1 from being circulated into the room as much as possible.

  FIG. 13 is a block diagram showing a configuration of a control system configured to perform fan drive control in accordance with door opening / closing operations. This drive system integrates a drive system for driving an automatic door and a drive system having a door pocket structure.

  The drive system for driving the automatic door includes a door drive control unit 64 that controls the drive unit 61 of the door 1 in the control unit 63 that performs overall control of the automatic door drive. A door position detection unit 62 is included in the drive unit 61 of the door 1. Each of these elements is supplied with power from a primary power source 65.

  The door pocket drive system has a system control unit (control means) 66, and the system control unit 66 drives and controls a fan 68 (corresponding to the fan 26 in the embodiment). A sub fan 69 indicated by a two-dot chain line may be added. The sub fan 69 may blow in the same direction as the main fan 68, or may blow in the opposite direction.

  When the air is blown in the same direction, the main fan 68 can be used to increase the wind when the air volume is insufficient. If the air is blown in the opposite direction, the upper fan 68 is driven when the main fan 68 is stopped, so that the upper suction / lower blowing operation is performed as shown in FIG. can do.

  Further, in the door bag structure drive system, the system control unit 66 can be supplied with power from the automatic door drive system and also can be supplied with power from the auxiliary power unit 71. A battery 72 is connected to the auxiliary power unit 71, and a power generation unit 73 using sunlight or wind power is connected to the battery 72 via a charge / discharge control unit 74. Accordingly, the fans 68 and 69 can be driven using the electric power generated by the power generation unit 73.

  Also, information on the opening / closing operation of the automatic door is input from the automatic door interlocking signal unit 67 to the system control unit 66 of the door pocket drive system. Thereby, drive control of the fans 68 and 69 can be performed according to the opening / closing operation | movement of an automatic door.

  FIG. 14 is a flowchart showing an example of the flow of fan control when the problems shown in FIGS. 10 to 12 are solved by the drive system of FIG.

  When this control starts, the fan motor is driven in step S1. Next, in step S2, the state of the door 1 is confirmed. In step S3, it is determined whether the door 1 is stopped at the closed end. When the door 1 is stopped at the closed end (fully closed state), it means that the door 1 is closed. Therefore, the process returns to step S2, and the drive of the fan motor is maintained.

  If the door 1 is opened, the determination in step S3 is NO, and the process proceeds to step S4 to stop the fan motor. Next, in step S5, the door state is confirmed, and in step S6, it is determined whether the door 1 has stopped at the closed end. If it is determined that the door 1 is not stopped at the closed end, it means that the door 1 is still open, so the process returns to step S4 and the fan motor is stopped.

  When the door 1 is closed and stopped at the closed end, the determination in step S6 is YES, and the process proceeds to step S7. In step S7, timer processing is performed, and in step S8, it is determined whether the timer time has elapsed. Until the timer time elapses, the process returns to step S5 in order to keep the fan motor stopped. When the timer time has elapsed, the process returns to the start, and the fan motor is driven in step S1. Here, the reason for setting the holding time with the timer is to prevent the fan from turning while the cold outside air stays around even if the door is closed.

  In the above description, the case where the lower suction operation is performed has been described. However, even when the lower blowing operation is performed (when the air is sucked from the upper ventilation port 25A and is blown from the lower ventilation port 24A), the door There is a possibility that the cold air that has entered during the opening will be engulfed by the air blown out from the vent 24A, and the inflow of the cold air may be promoted. This can be prevented by stopping the fan while the door is open.

  Moreover, in the said embodiment, although the indoor side panel 20 comprised the double panel structure of the outer panel 21 and the inner panel 22, and demonstrated the case where the ventilation path 23 was ensured between the outer panel 21 and the inner panel 22, In addition, an indoor panel can be configured as shown in FIG.

  That is, the indoor side panel 20B shown in FIG. 15A is composed of a honeycomb panel 81 having a plurality of spaces penetrating in parallel with each other in the vertical direction, and the plurality of spaces are used as ventilation paths. .

  The indoor side panel 20C shown in FIG. 15B is configured by a hollow panel 82 having a plurality of spaces penetrating in parallel with each other in the vertical direction, and the plurality of spaces are used as ventilation paths.

  The indoor side panel 20D shown in FIG. 15 (c) has a plurality of spaces penetrating in parallel to each other in the vertical direction by arranging a plurality of round pipes (or square pipes) in parallel in the vertical direction. And is used as a ventilation path.

  When these panels 81 to 83 are used, the upper ends of the plurality of ventilation paths 23 are communicated with the upper ventilation chamber 25 (see FIG. 1), and the lower ends are communicated with the lower ventilation chamber 24 (see FIG. 1). The same effect as that of the first embodiment can be expected. In addition, since many partition walls forming the ventilation path 23 exist in the indoor side panels 20B to 20D, the strength of the indoor side panels 20B to 20D can be increased, and the ventilation path 23 passes through. Heat exchange can be promoted by increasing the heat transfer area of the air and the indoor side panels 20B to 20D. That is, the indoor side panels 20B to 20D themselves can function as a heat exchanger.

  The present invention is not limited to the above-described embodiment described with reference to the drawings, and various modifications can be considered within the technical scope thereof.

  For example, FIGS. 15A to 15C describe the case where the entire indoor panel has the same panel structure, but the indoor panel is configured by a combination of FIGS. 15A to 15C. You can also. That is, a part of the width direction of the indoor side panel and the other part of the indoor side panel can have different panel structures.

  Of course, the indoor side panel may be composed of a transparent member or an opaque member, depending on the place where it is applied.
