Abstract

PURPOSE:To prevent giving an elevator passenger an uncomfortable sense of blowing sound even when the elevator is in high speed traveling, by equipping a drain tank of a peneumatic air conditioning device with an external surface of wind baffling property, locating this tank on the bottom surface side of a cage floor, and arranging an extra-room heat-exchanger while surface unevenness is lessened over the vertical outer wall surface of the cage. CONSTITUTION:A pump unit 10 of an air-conditioner installed at an elevator cage 1 is mounted through utilization of the space bounded by the ceiling 1b of the cage and the ceiling cover 1c. Because a drain tank 4' has an external surface of wind baffling property, the air received by the lower part of the cage can be baffled when the cage 1 is sinking, and further an extra-room heat-exchanger 9 is arranged while the surface unevenness is lessened over the vertical outer wall surface of the cage wall 1e, so that no turbulent air flow will be generated around the external-room heat-exchanger 9. This suppresses generation of blowing sound likely to occur when the cage is sinking, prevents discomfort of passengers in the cage, and provides an enhanced sense of riding comfort within the cage.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an elevator car device equipped with an air conditioner for heating and cooling a car interior.

[Prior Art] Figure 3 shows a conventional elevator car device.
In the figure, (1) is the basket, and (la) is the basket door.

(1b) Ceiling of the basket, (lc) Ceiling cover of the basket,
(k) is the car floor, (le) is the wall of the car, (l'') is the car room, and (2) is the hanging frame 2 (3) fixed to the bottom of the car floor (Id) and composed of angles, etc. (4) is an air conditioning unit that incorporates a refrigerant compressor, an outdoor heat exchanger with a blower (none of which are shown), etc. mounted on a hanging frame (2);
) is the drain tank also placed on the hanging frame (2),
(5) Basket ceiling (1b) and cage ceiling cover (1c)
(6) is the air inlet formed between the car ceiling (IC) and the car wall (LE), (7) is the same air outlet, (8) ) allows the air in the car room (If) to flow in from the suction port (6) and connects it to the indoor heat exchanger (5).
) and then sends the air to the air outlet (7).

Note that in Figure 1, piping for refrigerant and the like connecting each device is omitted.

A conventional elevator car device is configured as described above, and when the air conditioning unit (3) and the blower (8) are energized, the air in the car room (1r) is transferred from the air intake port (6) to the blower (
8) → Indoor heat exchanger (5) → Via the ventilation opening (7), the third
The air circulates as shown by arrow A in the figure, and the inside of the car (1r) is cooled or heated. At this time, the drain generated in the indoor heat exchanger (5) etc. is stored in the drain tank (4).

[Problems to be Solved by the Invention] A conventional elevator car device has an indoor heat exchanger that cools and heats the air in the car room (lf) in the space between the car ceiling (1b) and the car cover (1c). (5) and a blower (8), and a hanging frame (2) is installed on the bottom of the car floor (1d).
) is fixed, and the air conditioning unit (3) and drain tank (4) are placed on this hanging frame (2). Furthermore, since the air conditioning unit (3) incorporates an outdoor heat exchanger with a blower, the outer periphery of the hanging frame (2) is generally not covered with a cover or the like.

For this reason, the lower part of the car (1) in particular has a complicated shape with many unevenness, and when the car (1) descends, the air in the hoistway flows into the hanging frame (2), the air conditioning unit (3), and the drain tank. (4) generates turbulence, and the wind noise caused by this turbulence causes discomfort to the passengers in the car (1). In particular, the elevator speed of the car (1) is 150 per minute.
This effect was significant for high-speed elevators exceeding m.

This invention was made to solve the above-mentioned problems, and provides an elevator car device equipped with an air conditioner that does not cause discomfort to passengers due to wind noise even when the elevator is operated at high speed. It is intended to.

[Means for Solving the Problems] In the elevator car device according to the present invention, the car is equipped with an air conditioner, and the air conditioner has an air conditioning outer surface disposed on the bottom side of the car floor. A drain tank and an outdoor heat exchanger are installed along the vertical outer walls of the seven cars and perform heat exchange using the air flow generated around the cars when the cars go up and down.

[Function] In the elevator car device configured as described above, the drain tank of the air conditioner disposed on the bottom side of the car floor has an air-regulating outer surface, so that when the car descends, the car does not move. The air received by the lower part of the car can be rectified, and the outdoor heat exchanger is arranged along the vertical outer wall of the car with less unevenness, so when the car goes up and down, the area around the outdoor heat exchanger No airflow turbulence occurs.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. In the figure, (4') is a drain tank installed on the bottom side of the car floor (1d), and this drain tank (4')
has a wind-regulating outer surface with few irregularities.

(9) is an outdoor heat exchanger installed along the outer wall surface of the car wall (1e), and this outdoor heat exchanger (9) is installed around the car (1) when the car (I) goes up and down. Heat exchange is performed using the generated air flow, and when the car (1) goes up and down,
Components such as heat exchange fins or heat exchange pipes (none of which are shown) are incorporated with minimal unevenness to prevent turbulence. (10) is a pump unit equipped with a refrigerant compressor, etc. In Figure 2, the same or equivalent parts as in the conventional device 2 are denoted by the same reference numerals, and their explanation will be omitted.

In this embodiment, a drain tank having an air-regulating outer surface with few irregularities is disposed on the bottom of the car floor (1d), and an air conditioning unit (the third
3) in the figure is connected to the outdoor heat exchanger (9) and the pump unit (
10) and are installed separately from the bottom of the two cars (1). That is, the outdoor heat exchanger (9)
e) is arranged along the vertical outer wall surface of the pump unit (1
0) Car ceiling (lb) and car ceiling cover (1c)
It is arranged by making use of the space between.

Therefore, although the function of the air conditioner installed in the car (1) is the same as that of conventional equipment, since the drain tank (4') has a wind-regulating outer surface, the car (1) ) is lowered, the air received by the lower part of the car can be adjusted, and the outdoor heat exchanger (9) is connected to the wall of the car (1e
) is arranged with fewer irregularities along the vertical outer wall surface of the outdoor heat exchanger (9), so that no turbulence of airflow occurs around the outdoor heat exchanger (9).

In addition, in the conventional device shown in Fig. 3, the car floor (ld)
In an elevator with a small area, that is, a small capacity, the installation space on the hanging frame (2) is small, so the air conditioning unit (3) and drain tank (4) are placed on the hanging frame (2).
Some were unable to be equipped with air conditioners because it was difficult to place them side by side on top of each other.

However, according to this embodiment, only the drain tank (4') needs to be provided on the bottom side of the car floor (1d).
Even a small capacity elevator with a small car floor (1d) can be equipped with an air conditioner.

[Effects of the Invention] As explained above, the elevator car device according to the present invention has a drain tank for an air conditioner having an air-regulating outer surface disposed on the bottom side of the car floor, and furthermore, the elevator car device according to the present invention has a drain tank provided on the bottom side of the car floor. An outdoor heat exchanger that exchanges heat using the airflow generated in the surrounding area is installed along the vertical outer wall of the car, so even if the car is an elevator car equipped with an air conditioner.

When the car descends, the generation of wind noise can be suppressed, and the passenger comfort of the car can be improved without causing discomfort to the passengers in the car.
