Description

Elevator hall installation housing equipment

The present invention relates to an elevator hall installation housing apparatus that is installed in a hall and accommodates an elevator device such as an inverter.

In a conventional elevator control device, a plurality of heat generating components are housed in a casing installed in a hoistway. In addition, an intake port is provided in the lower front portion of the casing, and an exhaust port is provided in the upper front portion of the casing. Further, an exhaust fan is provided inside the exhaust port. Then, by driving the exhaust fan, cooling air flows in the housing (see, for example, Patent Document 1).

Also, in the conventional switchboard, an intake port is provided on the front surface of the housing, and an exhaust port is provided on the upper surface of the housing. The air taken into the housing from the air inlet is guided to the lower part of the housing by the air guide. An intake fan is provided in the air guide section. A filter is provided inside the intake port. A maintenance fan different from the intake fan is provided between the vent and the filter. Then, the clogging of the filter is eliminated by stopping the intake fan and operating the maintenance fan (see, for example, Patent Document 2).

As described above, when the amount of heat generated by the equipment housed in the housing is large and cooling is insufficient only by heat radiation from the housing surface, whether it is natural air cooling or forced air cooling, Vents and exhaust vents are provided.

On the other hand, when an enclosure is installed at a landing in an elevator, it is required to have a design affinity with the three-sided frame or the wall of the building. For this reason, in the housing | casing installed in a landing, it may be calculated | required to make a vent hole small. However, if the opening area of the vent is made small in consideration of design, the ventilation resistance increases.In the case of natural air cooling, natural convection is hindered and the cooling effect is reduced.In the case of forced air cooling, the required air volume is reduced. In order to ensure it, the wind speed increases at the vent and causes noise.

From the above, in general, the relationship between the cooling capacity and the design and quietness is contradictory, and it is difficult to accommodate a power module with a large amount of heat generation such as an inverter in the case installed at the landing.

On the other hand, an elevator in which a control panel is mounted on the back surface of the car door has also been proposed (see, for example, Patent Document 3).

In addition, an elevator has been proposed in which a control device is stored in a storage section provided on the landing side of the door pocket, and when the temperature in the storage section becomes high, the landing door is opened and closed to generate a wind flow in the storage section (for example, , See Patent Document 4).

Japanese Patent No. 4236075 JP 58-6010 A JP 2002-128402 A Japanese Patent No. 3961093

The conventional elevator control device disclosed in Patent Document 1 is not suitable for installation at a landing because of the appearance of large intakes and exhausts provided on the front surface of the housing.

The conventional switchboard disclosed in Patent Document 2 is also not suitable for an elevator installation housing device because of the appearance of a large air inlet on the front surface of the housing. In addition, since the air intake port is arranged at the upper part of the front surface of the housing, it is necessary to provide an air guide in the housing and guide the air taken into the housing from the air intake port to the lower part of the housing. The space inside the body cannot be used efficiently, and the casing becomes large.

The conventional elevator disclosed in Patent Document 3 requires that the thickness of the control panel be suppressed to the same level as the heat of the door panel, and that an impact is applied to the control panel each time the car door is opened and closed, so countermeasures against impact are necessary. There are many constraints and low feasibility, for example, because the door is heavy and the door drive capacity needs to be increased.

Since the conventional elevator shown in Patent Document 4 has no vent on the landing side, it is difficult to perform sufficient ventilation. Moreover, since the flow of a wind is produced by opening and closing of a landing door, the timing which can be cooled is restrict | limited. Furthermore, when the inside of the housing becomes hot, it is necessary to stop the operation and open / close the landing door, and the operation rate of the elevator is lowered. Furthermore, although the heat insulating material is affixed on the inner surface of the housing, it is for blocking heat applied from the outside, and does not radiate heat generated inside the housing.

The present invention has been made to solve the above-described problems, and can prevent deterioration in designability while ensuring sufficient air permeability, and can be used for landing installation of an elevator suitable for landing installation. The purpose is to obtain a body device.

An elevator hall installation housing apparatus according to the present invention is installed between a floor surface and a ceiling surface of a hall, and is provided with a lower ventilation hole and an upper ventilation hole, and accommodates elevator equipment. The lower vent is provided at the bottom of the chassis facing the floor, and the inside of the lower vent prevents foreign objects from entering the chassis from the floor. The foreign matter intrusion prevention unit includes a rising part that rises upward from the bottom of the housing, and a flat foreign substance removal part that protrudes from the upper end of the rising part toward the lower vent and faces the floor surface. Have.

In the elevator hall installation housing device of the present invention, the lower vent is provided at the lowermost portion of the casing facing the floor surface, and the foreign matter intrusion prevention portion having the rising portion and the foreign matter removal portion is provided inside the lower vent. Therefore, it is possible to prevent a decrease in designability while ensuring sufficient air permeability, and to be suitable for landing installation.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
1 is a perspective view showing an elevator hall installation housing apparatus according to Embodiment 1 of the present invention. Three-side frames 2 are provided on both sides and the upper part of the landing entrance 1. The three-way frame 2 includes first and second

vertical frames

3 and 4 disposed on both sides of the hall entrance 1 and an upper frame 5 disposed between the upper portions of the first and second

vertical frames

3 and 4. And have.

The hall entrance 1 is opened and closed by a pair of hall doors 6. A landing operation panel 7 is installed in the second vertical frame 4.

The hall installation casing device of the first embodiment has a casing 11 installed in front of the first vertical frame 3. The casing 11 is installed between the floor 8 and the ceiling 9 of the hall. The vertical dimension of the housing 11 is the same as the height from the floor surface 8 to the ceiling surface 9 (full height size). For this reason, the lower end of the housing 11 is in contact with the floor surface 8, and the upper end of the housing 11 is in contact with the ceiling surface 9.

The housing 11 has a housing body 12 and a door 13 provided on the front surface of the housing body 12 (the surface opposite to the first vertical frame 3). A front opening is provided on the front surface of the housing body 12. The front opening of the housing body 12 is opened and closed by a door 13.

The housing 11 is provided with a lower vent 14 that functions as an air intake when the interior is cooled, and an upper vent 15 that functions as an exhaust when the interior is cooled. The lower vent 14 is provided at the lowermost portion of the front surface of the housing 11 facing the floor surface 8. The upper vent 15 is provided at the uppermost portion of the front surface of the housing 11 facing the ceiling surface 9. The floor surface 8 forms part of the lower vent hole 14, and the ceiling surface 9 forms part of the upper vent hole 15.

The vertical dimension of the door 13 is smaller than the vertical dimension of the housing body 12. The lower end of the door 13 is located above the lower end of the housing body 12. As a result, a lower vent 14 is formed between the lower end of the door 13 and the floor surface 8. Further, the lower vent 14 is provided over the entire width direction of the housing 11.

The door 13 has a front surface portion 13a that is a flat plate portion facing the front surface opening of the housing body 12, and a pair of side surface portions 13b that project at right angles from both ends in the width direction of the front surface portion 13a to the housing body 12 side. ing. The upper end of the front surface portion 13 a is located below the upper end of the housing body 12. Thereby, the upper vent 15 is formed between the upper end of the front surface part 13a and the ceiling surface 9. The upper end of the side surface portion 13 b reaches the ceiling surface 9.

2 is a perspective view showing the casing 11 of FIG. 1, and FIG. 3 is a longitudinal sectional view of the casing 11 of FIG. The door 13 is rotatably attached to the housing body 12 via a plurality of hinges 16 (shown only in FIG. 2). In the housing body 12, a heating element 17 (not shown in FIG. 2) such as an inverter is accommodated as an elevator device.

A cooling fan 18 (not shown in FIG. 2) is provided above the heating element 17 in the housing body 12. By rotating the cooling fan 18, an air flow for cooling the heating element 17 is generated in the housing 11 as indicated by an arrow in FIG. 3. This cooling air flow is a flow that enters the housing 11 from the lower vent 14, travels upward in the housing 11, and is discharged from the upper vent 15 to the outside of the housing 11.

Inside the lower vent 14, a foreign matter intrusion prevention unit 19 that prevents foreign matter from entering the housing 11 from the floor 8 is provided. The foreign matter intrusion prevention unit 19 includes a flat plate-like rising portion 19a that rises upward from the bottom of the housing body 12, and a flat plate-like shape that protrudes horizontally from the upper end of the rising portion 19a toward the lower vent 14 and faces the floor surface 8. A foreign matter removing portion 19b.

The rising portion 19a is inclined so that the upper end is closer to the lower vent 14 than the lower end. The foreign matter intrusion prevention unit 19 is formed by bending the end portion on the lower vent 14 side of the bottom surface of the housing body 12. Further, the foreign matter intrusion prevention unit 19 is continuously formed over the entire width direction of the housing 11.

The notch 12a is provided in the lower end of the side part of both the width directions of the housing body 12. FIG. As a result, the foreign matter container 20 which is a space formed between the foreign matter intrusion prevention unit 19 and the floor surface 8 is parallel to the width direction of the surface of the housing 11 where the lower vent 14 is provided. Are open to the outside at both ends. The shape of the notch 12 a is a shape along the shape of the foreign matter intrusion prevention unit 19.

A wind guide plate 21 that forms a wind guide path 21 a that guides air that has entered from the lower vent 14 upward is provided in the lower part of the housing body 12. The air guide path 21 a is provided with a filter 22 that captures foreign matters (for example, dust with a small mass) that could not be removed by the foreign matter intrusion prevention unit 19.

A plurality of cleaning fans 23 are provided on the upper side of the filter 22 of the air guide path 21a. The cleaning fan 23 generates an air flow that causes the air in the housing 11 to flow backward toward the lower vent hole 14, and discharges foreign matter attached to the filter 22 from the lower vent hole 14. The upper ventilation hole 15 is covered with an upper ventilation wire mesh 24.

Although the cooling fan 18 and the cleaning fan 23 are not driven at the same time, it is preferable to use the

fans

18 and 23 that can secure a large cross-sectional area of the stopped air passage and have low airflow resistance. .

Next, the operation will be described. When the inside of the housing 11 is cooled, the cooling fan 18 is rotated and the cleaning fan 23 is stopped. Thereby, an air flow as shown by an arrow in FIG. 3 is generated, and the heating element 17 is cooled. At this time, the foreign matter accumulated on the floor 8 enters the lower side of the foreign matter removing portion 19b by the trap structure of the foreign matter intrusion preventing portion 19 and the centrifugal separation effect by the foreign matter's own weight, and is accommodated in the foreign matter containing portion 20. The

Further, the light weight foreign matter that has entered the casing 11 together with the air flow is captured by the filter 22. Thereby, the heat generating body 17 is cooled with clean air.

When cleaning the filter 22, the cooling fan 18 is stopped and the cleaning fan 23 is rotated. Thereby, an air flow as shown by an arrow in FIG. 4 is generated, and the foreign matter attached to the filter 22 is peeled off from the filter 22 by the wind pressure. Thereafter, the foreign matter is discharged out of the casing 11 from the lower vent 14 together with the air flow. Further, intrusion of foreign matter from the upper vent 15 into the housing 11 is prevented by the upper vent wire mesh 24.

The timing for operating the cleaning fan 23 can be set, for example, every time the car is started or every 24 hours. Further, it can be set so that the cleaning operation is periodically performed when the cooling operation in the housing 11 is unnecessary. By shortening the operation cycle of the cleaning fan 23 as much as possible, the foreign matter can be discharged while there are few foreign matters adhering to the filter 22 or accumulated in the lower part of the air guide passage 21a. A sufficient effect can be obtained.

In such an elevator hall installation casing device, the lower vent 14 is provided at the lowermost portion of the casing 11 facing the floor surface 8, so that the front portion 13a of the door 13 has a lattice shape, a mesh shape, an armor window, or the like. No opening processing is required. Moreover, even if the opening area of the lower vent 14 is increased to some extent, the lower vent 14 is arranged considerably below the user's line of sight, so it looks as if there is a slight gap on the floor surface 8 and is not noticeable. .

Further, when the lower vent 14 is simply arranged at the lowermost part of the casing 11, foreign matter on the floor surface 8 is easily sucked into the casing 11, and the filter 22 is easily clogged. On the other hand, since the foreign substance intrusion prevention part 19 having the rising part 19a and the foreign substance removal part 19b is provided inside the lower vent 14, the foreign substance on the floor surface 8 is hardly sucked into the housing 11.

Furthermore, since a sufficient opening area can be secured, it is possible to mount a power module used for an inverter having a large heat generation amount.

As described above, it is possible to prevent a deterioration in designability while ensuring sufficient air permeability, and it is possible to obtain a hall installation casing device suitable for hall installation.

Moreover, since the cleaning fan 23 is provided in the housing 11 together with the filter 22, the filter 22 can be easily cleaned. For this reason, the clogging of the filter 22 can be prevented, and failure due to overheating of the heating element 17 and life reduction can be prevented.

Furthermore, since the rising portion 19a is inclined, the foreign matter peeled off from the filter 22 can be more reliably discharged into the housing 11 when the filter 22 is cleaned.

Furthermore, since the foreign material container 20 is open to the outside at both ends, the foreign material can be made difficult to collect in the foreign material container 20, and the foreign material stored in the foreign material container 20 can be easily cleaned with a broom or the like. can do.

In addition, since the lower vent 14 is formed between the lower end of the door 13 and the floor surface 8 by positioning the lower end of the door 13 above the lower end of the housing body 12, The lower vent 14 can be made less noticeable.

Furthermore, since the upper vent 15 is provided at the uppermost part of the casing 11 facing the ceiling surface 9, the upper vent 15 can be made inconspicuous, and the front appearance of the casing 11 can be made flat. it can.

Furthermore, since the housing 11 is installed at the landing, it is possible to save the space of the hoistway and improve the maintenance workability of the elevator equipment in the housing 11.

The cleaning fan may also serve as a cooling fan as long as the motor of the cleaning fan can be rotated in the reverse direction and an air flow can be generated in the direction of cooling the elevator equipment.
Moreover, when the elevator apparatus in a housing | casing can fully be cooled only by the airflow by natural convection, you may make it carry out natural air cooling, without using a cooling fan.
Furthermore, the lower vent and the upper vent may be provided on the side surface of the housing.
Furthermore, when the upper vent is not conspicuous compared to the lower vent, such as when the vertical dimension of the casing is sufficiently large, the upper vent may be disposed below the uppermost portion of the casing.
Further, the lower vent and the foreign substance intrusion preventing portion may be provided only in a part of the width direction of the surface on which the lower vent is provided.
Furthermore, the foreign matter storage portion may be opened to the outside only at one end portion or may not be opened to the outside at both end portions.
Furthermore, the elevator apparatus accommodated in a housing | casing is not specifically limited.
The housing may also serve as a three-way vertical frame.
Further, the housing may be embedded in the building wall of the building as long as it does not hinder the opening and closing of the landing door.
