Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a cooling device for the upper surface of an elevator car (an elevator power installed to cool the inside of a multi-power car). .

(Conventional technology) In recent years, there has been an increasing trend in various buildings to air-condition the entire building. As a result, more and more elevators are equipped with air-conditioning devices that cool the inside of the elevator car in order to provide a more comfortable environment for passengers riding in the elevator.

Especially when glass windows are installed on the side wall of the hoistway of the building and on the car to receive direct sunlight, such as in an observation elevator.
Since the inside of the car gets hotter and the passengers feel more uncomfortable, it is more necessary to install an air conditioner.

By the way, as shown in FIG. 6 and FIG. 7, conventionally, as shown in FIG. 6 and FIG. Cool air from the air outlet 3a of the device main body 3 is sent into the car 1 through the introduction duct 4, and the air inside the car 1 is passed between the lighting case 6 of the ceiling lighting device 5 and the ceiling 2. It is configured to cool the inside of the car 1 by returning it to the cooling device main body 3 via the circulation duct 7 and circulating it repeatedly. Furthermore, such a cooling device main body 3 is provided with a front panel 8 having a mesh or lattice shape extending from the air outlet 3a to the suction port 3b connected to the circulation duct 7, and has an air filter inside the front panel 8. 9 is provided to remove dust, dirt, etc. from the circulating air inside the car 1.

In addition, a light source body 10 such as a fluorescent lamp is provided in the lighting case 6 of the ceiling lighting device 5, and a lighting plate 12 such as a louver or an acrylic plate is provided below the light source body 10 via a lighting frame 11. . In addition, according to laws and regulations, the ceiling 2 is provided with an opening/closable rescue exit 13 for passengers in the car in case of an emergency, and an inspection opening for inspecting the light source 10 and lighting board 12 of the ceiling lighting device 5 as necessary. 14 is provided so that it can be opened and closed.

(Problems to be Solved by the Invention) In the elevator car cooling system having the above configuration, the cooling system main body 3 is fixed to the upper surface of the ceiling 2 of the car 1, so when deciding the installation location, it is necessary to check the rescue exit 13 in advance. In addition, the installation space for the inspection port 14 must be taken into consideration, which places restrictions on the installation location. Conversely, there may be cases where the inspection port 14 cannot be provided at the desired position due to the space required to install the cooling device main body 3, and the ceiling lighting device 5
There was a problem in that it affected the arrangement and design of the light source body 10 and the illumination plate 12, impairing the design.

Further, as described above, if the cooling device main body 3 is fixed, there is a problem that maintenance work for the cooling device main body 3 itself becomes troublesome. In other words, if the air filter 9 becomes clogged, the cooling capacity will decrease, so occasionally open the front panel 8, take out the air filter 9 inside, and clean the collected dirt and dust. However, since the front panel 8 is in close contact with the introduction duct 4 and circulation duct 7, the front panel 8 cannot be opened unless the introduction duct 4 and circulation duct 7 are removed. The work was very tedious.

The present invention has been developed in view of the above circumstances, and it is possible to install the main body of the air conditioner on the upper surface of the ceiling of the car without being blocked by other rescue exits or inspection entrances. To provide a cooling device for an elevator corner, which can eliminate problems that affect the design and impair the aesthetics, and also allows maintenance work such as inspection and maintenance to be performed very easily.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above-mentioned object, the cooling device for an elevator car of the present invention has the following features: It is characterized by being installed so that it can be moved to any position.

(Function) With the above configuration, in the elevator car cooling device of the present invention, the cooling device main body can be moved from a predetermined position to another position via the guide rail with respect to the ceiling upper surface of the car. The installation location of the cooling device body can be selected regardless of the installation space on the upper surface of the ceiling such as a rescue exit or an inspection entrance. In addition, when performing maintenance such as inspection and maintenance of the cooling system, the main body of the cooling system can be slid to a convenient location away from the introduction duct via the guide rail, making maintenance work very easy. .

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 5. Components in the figure that overlap with those shown in FIGS. 6 and 7 are given the same reference numerals to simplify the explanation.
