Description

  The present invention relates to an elevator apparatus that raises and lowers a car between a low-rise floor and a high-rise floor.

  In an elevator apparatus provided in a high-rise building such as a building, an upward airflow may be generated in the interior space of the elevator shaft due to the chimney effect. Due to this updraft, air is taken in from the lower floor of the building and released from the upper end of the elevator shaft and the upper floor of the building. And when an updraft is too strong, the external air will be taken in in a building and the malfunction that air-conditioning efficiency will worsen arises. In addition, the air sucked into the elevator shaft causes a problem that the opening and closing of the elevator door is hindered.

  Various techniques have been proposed for suppressing the upward airflow that causes such problems. For example, in Patent Document 1, the temperature inside the elevator shaft is detected by a temperature sensor installed in the elevator shaft, and outside air is sucked into the elevator shaft according to the detection result, or the air inside the elevator shaft is extracted from the outside of the building. The device for discharging is described.

  Further, Patent Document 2 includes an air flow meter, an anemometer, a noise meter, and the like. The draft detection means provided in the elevator shaft and the upper and lower sides of the building are provided. A device is described that includes a passage communicating with the outside and a controller that is provided in the middle of each passage and that changes an opening area of each passage, and that controls the controller according to the detection result of the draft detection means. Yes.

All of the devices described in the above-mentioned patent documents control intake / exhaust air to the elevator shaft and the opening area of each passage so as not to generate ascending airflow in the interior space of the elevator shaft. For this reason, there has been a problem that fine control is required.
This invention is made | formed in view of such a situation, The objective is to suppress the malfunction by the upward airflow in the elevator shaft which arises by a chimney effect by an easy means.

  In these inventions, when air rises in the interior space of the elevator shaft due to the chimney effect, air is sucked from the outside of the building through the lower communication portion. The sucked air rises in the internal space and is discharged outside the building through the upper communication part. That is, a series of air flow paths that are connected from the lower communication portion to the upper communication portion through the internal space are formed. As a result, the chimney for the part corresponding to the use floor in the interior space of the elevator shaft, that is, the part below the communication part with the lower communication part and the part above the communication part with the upper communication part. Generation of upward airflow due to the effect can be suppressed. As described above, since the generation of the updraft in the portion corresponding to the use floor is structurally suppressed, the adverse effect of this updraft can be easily suppressed without special control.

  In the present invention, the lower communication portion includes a lower flapper that can be controlled to open and close at the boundary with the outside of the building, and the upper communication portion includes an upper flapper that can be controlled to open and close at the boundary with the outside of the building. preferable. Thus, by providing a flapper in the lower communication part or the upper communication part, it is possible to suppress a problem that rain winds enter the communication parts during stormy weather such as a typhoon.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  A building 1 illustrated in FIG. 1 includes an indoor elevator device 2. This indoor type elevator apparatus 2 is an elevator apparatus in which an elevator shaft 3 is provided on the inner side in the plane direction than the outer wall of the building 1. Building 1 has 14 floors, and the 1st to 3rd floors and the 12th to 14th floors are the elevator use floors. That is, the elevator apparatus 2 is directly operated between the first floor to the third floor, the lower floor usage floor, and the 12th floor to the 14th floor, the higher floor usage floor. Such an elevator apparatus 2 is installed, for example, when an observation space is provided on a high-rise use floor or a restaurant is provided. In addition, the 4th floor to the 11th floor in this building 1 are floors where the elevator is not used, and the entrance / exit for the elevator apparatus 2 (shaft side door 8) is not provided.

  The elevator apparatus 2 includes an elevator shaft 3, a car 4, a machine room 5, a lower duct 6, and an upper duct 7.

  The interior space of the elevator shaft 3 serves as a passage (hoistway) for the car 4 to move up and down. In this elevator shaft 3, a shaft side door 8 serving as an elevator entrance / exit is provided on each floor of the lower floor usage floor portion 3 a corresponding to the first floor to the third floor and the higher floor usage floor section 3 b corresponding to the 12th floor to the 14th floor. ing. These shaft side doors 8 are provided at positions facing a car side door (not shown) of the car 4. Then, when the car 4 is stopped on the use floor, the user gets on and off by opening the shaft side door 8 and the car side door.

  The car 4 is a part that carries a user and moves up and down in the hoistway. The machine room 5 is installed on the roof of the building 1 and accommodates a motor 5a and a pulley 5b for moving the car 4 up and down. The motor 5a is power for rotating the pulley 5b. A wire 5c for suspending the car 4 is wound around the peripheral surface of the pulley 5b. For this reason, when the motor 5a is operated, the pulley 5b rotates and the wire 5c is drawn out or wound up, so that the car 4 can be raised and lowered. In this elevator apparatus 2, the passenger car 4 passes from the fourth floor to the eleventh floor, which are non-use floors. For this reason, the range corresponding to the 4th floor to the 11th floor in this building 1 corresponds to the pass range between the 1st floor to the 3rd floor (low-rise use floor) and the 12th floor to the 14th floor (high-rise use floor).

  The lower duct 6 is a part that communicates the interior space of the elevator shaft 3 to the outside of the building on the lower floor use floor side of the pass range, and corresponds to a lower communication part. The lower duct 6 in this embodiment is provided on the fourth floor, which is the floor directly above the lower floor use floor. Specifically, it is provided in a substantially horizontal direction in the ceiling space on the fourth floor. Thus, if the lower duct 6 is provided in the ceiling space, the space in the building can be used effectively. Further, the lower duct 6 can be hidden from the living room portion, and the aesthetics can be improved. A flapper 9 (lower flapper) is provided in the opening 10 on the building outer wall side in the lower duct 6.

  The upper duct 7 is a part that communicates the interior space of the elevator shaft 3 to the exterior of the building on the upper floor use floor side in the pass range, and corresponds to the upper communication part. The upper duct 7 in this embodiment is provided on the eleventh floor, which is directly below the high-rise use floor. Specifically, it is provided substantially horizontally in the ceiling space on the 11th floor. As a result, the space is effectively utilized and the aesthetics are improved. A flapper 9 (upper flapper) is also provided in the opening 10 on the outer wall side of the upper duct 7.

  The shape of the lower duct 6 is such that the amount of air flowing through the lower duct 6 is greater than the amount of air flowing through the lower floor use floor portion 3a of the elevator shaft 3 (the portion below the communication point with the lower duct 6). Determined. Similarly, the shape of the upper duct 7 is also such that the amount of air flowing through the upper duct 7 is greater than the amount of air flowing through the upper floor use floor portion 3b of the elevator shaft 3 (the portion above the communication point with the upper duct 7). It is determined to increase. In other words, the shape of the lower duct 6 is determined so that air can flow more easily than the low-rise use floor portion 3a (so that the flow path resistance becomes low), and the shape of the upper duct 7 is made higher than that of the high-rise use floor portion 3b. Is also determined so that air can flow easily. Here, the amount of air flowing through each duct 6, 7 is mainly determined by the opening area of each duct 6, 7, the length of each duct 6, 7, and the pressure difference at the duct inlet / outlet. Therefore, the shape of each duct 6 and 7 is defined by defining the opening area and length of each duct 6 and 7.

  As shown in FIG. 2, the flapper 9 provided in each of the ducts 6 and 7 is a rectangular plate material, and is attached to the openings 10 and 10 of the respective ducts 6 and 7 in a state where the upper end is rotatable. Then, by operating a motor (not shown), the flapper 9 closes the opening 10 (state indicated by a solid line), and the flapper 9 has a lower end separated from the opening 10 (state indicated by a two-dot chain line). ) And can be switched to. In the present embodiment, the flapper 9 is normally opened, but is closed during stormy weather. This prevents rain and wind from entering the duct.

  Further, since the vicinity of the opening 10 in each duct 6 and 7 is the rising portions 6a and 7a that rise above the opening 10, entry of rain and wind into the duct can be prevented also in this respect. Further, the flapper 9 is fixed obliquely downward when opened. Thereby, the flapper 9 functions like a roof when opened, and guides rain from above obliquely downward. In this respect as well, rain and wind can be prevented from entering the duct.

  Next, the operation of the elevator apparatus 2 will be described. Here, Fig.3 (a) is a figure explaining the flow of the air in the building which may arise by a chimney effect. FIG. 3B is a view for explaining the pressure distribution due to the chimney effect in the elevator shaft 3.

  In the pressure distribution diagram of FIG. 3B, the state where the outside air pressure and the internal pressure of the elevator shaft 3 are equal is indicated by [0]. A state where the internal pressure of the elevator shaft 3 is lower than the outside air pressure is indicated by [−], and a state where the internal pressure is higher than the outside air pressure is indicated by [+]. Therefore, in the [−] state, air flows from the outside of the building 1 toward the elevator shaft 3, and in the [+] state, air is discharged from the elevator shaft 3 toward the outside. Here, there is no air flow between the outside and the elevator shaft 3 at a height at which the [−] state and the [+] state are switched, that is, a height at which the internal pressure and the outside air pressure are balanced. . Such height is referred to as neutral points X1 to X3.

  As shown in FIG. 3A, when the air in the elevator shaft 3 is warmed, an updraft is generated in the internal space. Here, as shown in FIG. 3 (b), air flows through the lower duct 6 more easily than the lower use floor portion 3a, and air flows more easily through the upper duct 7 than the higher use floor portion 3b. In addition, the portion corresponding to the eaves passage range of the elevator shaft 3 (referred to as eaves passage portion 3c), the low-rise use floor portion 3a, and the high-rise use floor portion 3b are cut off with respect to pressure. That is, the outside air introduced from the upper duct 7 eliminates the influence of the pressure distribution of the low-rise use floor portion 3a and the high-rise use floor portion 3b in the soot passage portion 3c. As a result, the pressure distribution in the eaves passage portion 3c becomes independent from the pressure distribution in the low-rise use floor portion 3a and the high-rise use floor portion 3b, and becomes the pressure distribution shown in FIG.

  Here, the height of the eaves passage part 3c (for the eighth floor in this embodiment) is larger than the height (for the third floor in the present embodiment) of the low-rise use floor part 3a and the high-rise use floor part 3b. For this reason, the soot passing portion 3c is more strongly affected by the chimney effect than the low-rise use floor portion 3a and the high-rise use floor portion 3b. As a result, a large amount of outside air is taken in from the lower duct 6 due to the rise of air in the soot passage portion 3c. In addition, the air that has risen in the eaves passage portion 3 c flows into the upper duct 7 and is discharged to the outside of the building 1. That is, a series of air flow paths that pass through the lower duct 6, the eaves passage portion 3 c, and the upper duct 7 are formed. On the other hand, since the low floor usage floor portion 3a and the high floor usage floor portion 3b are low in height, the pressure difference due to the updraft becomes small. Further, the air that has risen in the soot passage portion 3 c flows into the upper duct 7. Thus, the flow of air due to the chimney effect is suppressed in the low-rise use floor portion 3a and the high-rise use floor portion 3b.

  Here, the reason why the flow of air is suppressed will be described in more detail with reference to FIGS. 4 (a) and 4 (b). For convenience, in these figures, only the left half is described for the low-rise floor and only the right half is listed for the high-rise floor. Moreover, about the pass range, only the pass part 3c in the elevator shaft 3 is described, and the description about the passing floor is omitted.

  As shown in FIG. 4A, due to the clearance of the shaft side door 8 (see FIG. 1), the windows on each floor, etc., the resistance R11 for air etc. in the first floor part and the resistance R12 in the second floor part. However, it is assumed that a resistor R13 is formed on the third floor part, and a resistor R14 is formed on the lower duct 6. Similarly, in the elevator shaft 3, a resistor R21 is formed in the eaves passage portion 3c. Further, a resistor R31 is formed in the upper duct 7, a resistor R32 is formed in the 12th floor portion, a resistor R33 is formed in the 13th floor portion, and a resistor R34 is formed in the 14th floor portion.

  Here, the elevator shaft 3 and each use floor (the first floor to the third floor, the 12th floor to the 14th floor) are narrow gaps formed by the shaft side door 8, for example, between the opposing side edges of the two door plates. It is only connected by the clearance gap formed in this, and the clearance gap formed between the shaft side door 8 and a wall. On the other hand, the lower duct 6 and the upper duct 7 are configured as air flow paths having a sufficiently large opening area. Therefore, the resistances R11 to R13 of the first to third floor parts are sufficiently larger than the resistance R14 of the lower duct 6, and the resistances R32 to R34 of the twelfth to fourteenth floor parts are resistance R31 of the upper duct 7. Than enough to be.

  In addition, since the machine room 5 is installed above the elevator shaft 3, the air flow path in this part is only as large as a gap. For this reason, the resistance at the upper end of the shaft is sufficiently large. Moreover, since the bottom part of the elevator shaft 3 is blocked, air enters and exits between the first-floor shaft portion and the first-floor floor portion through a gap in the shaft-side door 8 portion.

  As shown in FIG. 4 (b), when the air in the interior space of the elevator shaft 3 is warmed and rises, the resistance R14 is sufficiently smaller than the resistances R11 to R13. Flows into 3c. Since the resistance R31 of the upper duct 7 is sufficiently smaller than the resistances R32 to R34 of each floor portion and the resistance of the upper end of the duct, the air that has risen up the eaves passage portion 3c passes through the upper duct 7 to the outside of the building 1. Discharged. Thereby, the heat in the elevator shaft 3 can be released to the outside.

  The internal pressure P21 at the portion where the lower duct 6 communicates with the internal space of the elevator shaft 3 is slightly lower than the inlet pressure P12 of the lower duct 6 due to the influence of the resistance R14. The internal pressure P21 ′ having a height corresponding to the first floor portion is approximately the same as the internal pressure P21 because the resistance of the internal space in the elevator shaft 3 is sufficiently small. Further, the inlet pressure P11 of the first floor portion is substantially the same as the inlet pressure P12. For this reason, the air sucked from the outside flows into the lower end portion of the internal space in the elevator shaft 3 through the first floor portion.

  Here, the edge is cut | disconnected regarding the pressure in the low-rise utilization floor part 3a and the eaves passage part 3c. Therefore, the lower floor use floor portion 3a shows a pressure distribution independent of the eaves passage portion 3c, and the second floor floor portion above the neutral point X1 and the third floor floor portion from the elevator shaft 3 side to the outer wall side of the building 1 Air flows into In this case, since the pressure difference between the internal pressure P21 and the inlet pressure P11 is small, it is possible to suppress problems caused by the pressure difference, for example, it is difficult to open and close the shaft side door 8. In addition, the resistances R11 to R13 are due to the clearance of the shaft side door 8 part, and coupled with the fact that the resistances R11 to R13 are sufficiently larger than the resistance R14, it is possible to reduce the amount of air flowing through the low-rise use floor part 3a.

  Moreover, the edge is cut | disconnected regarding the pressure also between the high-rise utilization floor part 3b and the eaves passage part 3c. Therefore, the high-rise use floor portion 3b also exhibits a pressure distribution independent of the eaves passage portion 3c, and air flows from the outside of the building into the interior space of the elevator shaft 3 through the 12th floor portion below the neutral point X3. . Here, the internal pressure P22 at the portion where the upper duct 7 communicates with the internal space of the elevator shaft 3 is slightly higher than the outlet pressure P31 of the upper duct 7 because the resistance R31 is small. And since the outlet pressure P31 is substantially the same as the inlet pressure P32 of the 12th floor part, the influence of the internal pressure P22 is negligibly small for the inflow of air from the 12th floor part.

  Therefore, air flows in from the 12th floor portion due to the chimney effect in the high-rise use floor portion 3b, but the amount is a small amount corresponding to the height of the third floor. In addition, for the 13th floor part and the 14th floor part above the neutral point X3, the air from the elevator shaft 3 side flows to the outer wall side of the building 1, but the amount of flowing air is the same as that of the 12th floor part. Similarly, it will be less. Therefore, the amount of air flowing through the high-rise use floor portion 3b is also sufficiently smaller than the amount of air flowing through the eaves passage portion 3c.

  As described above, in the building 1 in which the elevator apparatus 2 of the present embodiment is installed, the lower duct 6 and the upper duct 7 are communicated with the eaves passage portion 3c through which the car 4 passes. A series of air flow paths including the passage portion 3c and the upper duct 7 are formed. And by this air flow path, the air warmed in the interior space of the elevator shaft 3 can be positively discharged from the upper duct 7. Thereby, the excessive temperature rise in the elevator shaft 3 can be suppressed.

  For example, as shown in the simulation result example of FIG. 5, in the conventional structure in which the lower duct 6 and the upper duct 7 are not provided, the temperature in the shaft is often 40 ° C. or more, and the temperature difference from the outside air is more than a dozen degrees C. From tens of degrees Celsius. In this regard, in the structure to which the present invention is applied, the temperature inside the shaft can be suppressed to several degrees higher than the temperature of the outside air by providing the lower duct 6 and the upper duct 7 to form the air flow path.

  Moreover, the edge regarding a pressure can be cut | disconnected between the eaves passage part 3c, the low-rise utilization floor part 3a, and the high-rise utilization floor part 3b regarding the elevator shaft 3. FIG. For this reason, in the low-rise utilization floor part 3a and the high-rise utilization floor part 3b, the pressure difference with outside air can be made small enough, and the malfunction resulting from a chimney effect can be suppressed. Specifically, it is possible to suppress the opening / closing failure of the shaft-side door 8 due to the pressure difference being too large, noise due to the excessive amount of flowing air, and the like.

  For example, as shown in the simulation result example of FIG. 6, in the conventional structure, the difference (maximum value) between the pressure inside the shaft and the pressure outside the building is 15 to 40 mmAq, whereas in the structure to which the present invention is applied, The pressure difference can be suppressed to about 3 to 7 mmAq.

  By the way, the present invention is not limited to this embodiment, and various modifications are possible. For example, in the above-described embodiment, the indoor type elevator apparatus 2 is taken as an example, but the present invention is not limited to this type of elevator apparatus. For example, as shown in FIG. 7, an outer wall side installation type elevator apparatus 2 ′ in which an elevator shaft 3 ′ having a transparent wall portion is installed in a state in which a part is exposed to the outside of the building 1 may be used. In the case of this elevator apparatus 2 ′, as shown in FIGS. 8A and 8B, an opening 10 may be provided in the wall portion of the elevator shaft 3 ′. In this case, the opening 10 corresponds to a lower communication portion or an upper communication portion that communicates the internal space of the elevator shaft 3 ′ with the outside of the building. In this elevator apparatus 2 ′, the wall of the elevator shaft 3 ′ is transparent, so that the temperature in the shaft is likely to rise due to sunlight, and an upward air flow is likely to be generated. By providing, it is possible to easily suppress problems caused by the rising airflow. Also in this embodiment, an openable / closable flapper 9 is provided in the opening 10. Therefore, it is possible to prevent rain and wind from entering the internal space during stormy weather.

  In the above-described embodiment, the building 1 is exemplified as the building where the elevator apparatus 2 is provided. However, the tower 20 may be used as shown in FIG. The illustrated tower 20 is provided with two observation decks 22 and 23 having different heights in addition to the lower floor 21. That is, a lower first observation platform 22 and an upper second observation platform 23 are provided. No living room space is provided between the lower floor 21 and the first observatory 22 and between the first observatory 22 and the second observatory 23. In this tower 20, in the relationship between the lower floor 21 and the first observation deck 22, the lower floor 21 corresponds to the lower floor usage floor, and the first observation deck 22 corresponds to the higher floor usage floor. Moreover, in the relationship between the 1st observation deck 22 and the 2nd observation deck 23, the 1st observation deck 22 corresponds to a low-rise utilization floor, and the 2nd observation deck 23 corresponds to a high-rise utilization floor.

  In the above-described embodiment, the lower duct 6 is provided on the upper floor of the low-rise use floor and the upper duct 7 is provided on the lower floor of the high-rise use floor. However, the lower duct 6 may not be on the upper floor or the lower floor. That is, if the pressure difference or temperature difference with the outside air in the lower floor usage floor portion 3a or the higher floor usage floor portion 3b of the elevator shaft 3 or the amount of air flowing through these portions is within an allowable range, the ducts 6 and 7 are connected. You may change the height position to provide. In short, the lower duct 6 should just be provided in the lower half part in the eaves passage part 3c, and the upper duct 7 should just be provided in the upper half part in the eaves passage part 3c.

  Moreover, regarding the lower duct 6 and the upper duct 7, the lower duct 6 and the upper duct 7 are provided in the ceiling back space in the above-described embodiment, but may be provided in an underfloor slab. For example, as shown by a one-dot chain line in FIG. 1, when the lower duct 6 is provided in the underfloor slab in the upper floor of the low-rise use floor, the eaves passage portion 3 c in the elevator shaft 3 is connected from the ceiling space to the underfloor slab. The length can be increased by the height difference, and the temperature rise in the shaft can be reliably prevented. Moreover, since the length of the low-rise utilization floor part 3a and the high-rise utilization floor part 3b can be shortened, the raise of the air in these parts can be suppressed more.
