Definitions
- Each elevator car is equipped with a device for ventilation according to a regulation for lifts EN 81 - 1: 1998 + A3: 2009 in an upper area and a lower area.
- the various embodiments described here relate to such a device for ventilating elevator cars in elevator installations.
- Known exemplary elevator systems consist of an elevator car, a counterweight and a suspension element, which connects the elevator car and the counterweight with each other via a drive. By this drive, the elevator car is moved in an elevator shaft.
- a ventilation system is provided, which is required for an air change in the elevator car. This creates a dynamic air flow in the elevator car due to back pressure on this elevator car.
- EP 04185 1 1 describes a device for the ventilation of elevator cars, wherein in a elevator car, generated by wind and dynamic pressure on the air-displacing elevator car, a vertical air flow is created.
- a ventilation duct in an upper area of the elevator car consists of primary air openings, chambers, air ducts and secondary air openings.
- the chambers and air ducts are formed by panels and spoilers.
- the wind deflectors calm the airflow.
- the wind deflectors and the panels are provided with a material for noise reduction.
- the problem with such a solution is an elaborate equipment of the ventilation duct with the material for noise reduction.
- the object of the invention is therefore to provide a ventilation device which generates a ventilation channel by a simpler design of components with simultaneous effective noise insulation in the cabin interior.
- an elevator car which is installed in an elevator shaft, wherein a ventilation device is attached to a cabin outer surface, said ventilation device forms at least one ventilation channel, wherein the at least one ventilation channel has at least one primary ventilation opening, which allows an exchange of air between the ventilation duct and the elevator shaft, wherein at least one of the cabin outer surfaces at least one secondary ventilation opening comprising, which allows an exchange of air between a cabin interior and the at least one ventilation duct, with at least one element of insulating material, wherein the at least one element substantially determines a profile of the at least one ventilation duct.
- the invention is based on the finding that a simplified embodiment of the ventilation device simplifies production and minimizes costs.
- a combination of a shaping of the ventilation channel with a lining of this ventilation channel by means of insulating material saves installation and production costs.
- At least one of the ventilation channels is rectilinear.
- Advantage is a simple production, since the ventilation channels can be easily inserted into the material of the element.
- the ventilation channels are produced by bores.
- At least one of the ventilation channels has bends.
- the advantage of this development is an increased noise insulation during operation of the ventilation device.
- the at least one ventilation channel is formed by a single element, wherein one or more substantially rectilinear ventilation channels are formed by a recess in this element.
- Advantage of this development is a possible simple installation of the ventilation device, since the installation of the ventilation device is limited to only this element.
- Another advantage of this development is that only one material is processed in a production of the ventilation device.
- at least one support is arranged in the at least one ventilation channel. The advantage of such a support is increased stability of the ventilation channel.
- the ventilation device consists of two elements, wherein both elements determine a profile of the at least one ventilation channel.
- Advantage is a freedom of design of the ventilation ducts during assembly of the ventilation device. Also advantageous is a choice of one of the two elements, which increases the stability of the ventilation device.
- At least one element of the ventilation device has porous regions, the air flowing through these porous regions, these porous regions at least partially forming the at least one ventilation channel.
- Advantages of this embodiment are a possible simple fabrication of the ventilation device and a stable configuration of the ventilation channel. Further advantages are a possible filtering effect of this porous region as well as a calming of the air flow in the ventilation channel. This calming of the air flow leads to a minimized noise load by the ventilation device.
- At least one of the elements of the ventilation device is adhesively fixed to one of the cabin outer surfaces. Advantage is a simple and time-saving installation of the ventilation device on the cabin outer surface, since no further holes or fasteners are necessary for a fixation of the element to the elevator car.
- one of the ventilation devices is arranged on the cabin roof and part of a baseboard.
- a combination of the skirting board with the ventilation device saves installation effort and costs.
- At least one of the ventilation devices is arranged on the cabin wall.
- the advantage is a space saving on the car roof or on the cabin floor.
- the ventilation device has a cable guide. The advantage is a protection of the cable guided therein by the ventilation device.
- ventilation ducts are arranged on one of the cabin outer surfaces, wherein at least one secondary ventilation opening allows air exchange between the ventilation ducts and the cabin interior, wherein the ventilation duct has a primary ventilation opening, wherein the at least one a primary vent opening allows air exchange between the vent duct and the elevator shaft, wherein at this primary vent a fan is arranged so that an air flow through the vent duct can be generated substantially only by the operation of the fan, wherein an air exchange between the at least one ventilation duct and the ventilation duct can only be done by the cabin interior and / or the elevator shaft.
- a device according to this claim can be designed with minimal requirements and benefits, since a ventilation through the ventilation channels exclusively has a complementary effect on the ventilation of the cabin interior. It is therefore also advantageous that only one fan of small design is necessary and can be positioned to save space. Thus, the device according to this claim can be additionally protected against damage.
- the fan is switchable.
- the advantage is that the fan only needs to be operated when needed. This is possible, for example, after a longer standstill.
