Definitions
- the invention relates to a door device with at least one door for opening and closing a passage, in particular a passage into the shop, comprising at least one door which is movably mounted on a door holder and comprising a blower generating an air curtain in front of the passage.
- Such door devices are used to protect the sales rooms against the ingress of cold air, so as to optimally design the climate inside the sales room, while at the same time preventing air currents coming from outside from suddenly entering the interior.
- a first arrangement which provides a double wing door, door brackets are provided.
- a column for the air outlet of the blower is provided in front of the door brackets on the outside, the column on the side facing the passage having both an air inlet and an air outlet side. It has been shown that such shields do not work properly, since the arrangement of inlet and outlet openings next to one another does not result in a proper air curtain before the passage. The effect of this arrangement cancels itself.
- the object of the invention is therefore to design a door device of the type mentioned at the outset in such a way that a safe shielding of the passage is ensured that only a small amount of energy is required to generate the air curtain. Furthermore, going through such a shielded doorway should not be uncomfortable for the user. Finally, the door device itself should be easy and inexpensive to assemble and manufacture.
- This object is achieved according to the invention in that the door holder has a receptacle with an air outlet opening on the side of the door, that the receptacle and the elongated outlet opening essentially extend over the entire height of the door and that the air inlet opening is remote from the outlet opening the air curtain emerging from the outlet opening shields the passage.
- the outlet opening extends over the door height has the advantage that there is overall a large shield which shields the entire passage.
- the main advantage is that the receptacle has an air inlet opening on the side facing away from the door. This ensures that the receptacle exits and enters on different sides of the door. No expensive heating for heating the air therefore needs to be created to generate the shielding air curtain. It is also advantageous if the door bracket is constructed like a post in order to be able to carry out a simple installation, since only one post has to be installed in the passage.
- the door holder prefferably receives a blower, in particular a tangential fan, which generates the air curtain, in which case the air curtain is generated directly in front of the outlet opening, while suction takes place on the other side of the post.
- a blower in particular a tangential fan
- the door jambs and the doors themselves are easy to install; in particular, subsequent changes in the wall opening do not have to be carried out in order to be able to carry out the installation.
- the door jamb with fan can be supplied with the doors at the same time in order to make installation as simple as possible.
- the post picks up the door and outlet on one side and the entrance on the other.
- the receptacle of the door holder with the inlet and outlet opening has a size that corresponds approximately to twice the diameter of the rotor of the tangential fan.
- the inflow angle of the air flow with respect to the line formed by the closed door is 7 °.
- the air flow points away from the door, so that pointing away when the door is open contains reliable protection against the ingress of air, in particular cold air.
- Such an air flow that blows away from the door also allows a secure seal to be guaranteed.
- the air flow emerging from the outlet opening is at a speed of at least 2 m per second. At such a speed, there is a secure seal when the door is open. It also ensures that no outside air can enter the room closed by the door. It is advisable here for the outlet opening to be on the outside of the passage, while the inlet opening, in particular, is on the inside of the passage. As a result, air can be sucked out of the interior, which is already heated and which is used to generate the air curtain and thus creates a safe, comfortable shield. In addition, air is renewed to a certain extent inside without fresh air being blown in.
- the door device comprises two doors, each door holder having a receptacle with an outlet opening.
- a double door can be created in a simple manner, which is important in large stores.
- the door holder carries a sensor for monitoring on the side facing the passage.
- this sensor it is possible, on the one hand, to detect any interfering objects in the path of movement of the door and thus to brake a door movement, and, on the other hand - what is even more important - is the possibility of creating an anti-theft device via the sensor, that is, if from the store Goods that are not yet exempt from theft protection can be removed from the door without having to set up special shelves or delimitation parts.
- the area of application of the door device according to the invention is thus enlarged.
- the pivoting movement of a door designed as a door leaf is detected by a sensor on both sides of the pivoting movement of the door leaf. In this way it is ensured that there is security against objects in the movement path or an anti-theft device in both movement sections.
- the opening created in the passage is shielded by the air curtain of the fan of the one door.
- the other fan of the closed door either does not run at all or under partial load in order to save energy in this way.
- the inlet opening of the blower is preceded by an air duct, the boundary of which is constructed from a double-walled pane which has an air inlet on the side of the door facing away from the door holder, the interior of the double pane forming the air duct.
- This disc-like air duct allows the air supply to be optimally carried out to the inlet opening of the blower of the receptacle.
- the inside of the limiting disc of the air duct is coated to such an extent that constant moisture can be removed.
- these panes are cooled or heated by the introduced air flow, whereby the cooling of the temperature of the air curtain can be heated.
- the fan arranged in a receptacle is designed as a tangential fan, in which case the motor has a rotor section on both sides of the axis of rotation. This measure allows a high stability of the tangential fan, so that it can be operated with a higher output and thus more effectively and effectively.
- 1 shows the passage closed with a door device
- 2 is a top view of a door bracket with a double door
- FIG. 3 is a top view of the other door bracket with the second wing door
- Fig. 6 shows the door device as a double door with an air duct.
- the door device 10 shown in Fig. 1 has two post-like door brackets 1 1, to each of which a wing door 12 is attached.
- the wing door is pivoted about an axis of rotation 24 on the post-like door bracket 11 by means of door hinges 22.
- a receptacle 13 is provided in the interior of the door holder 11.
- This receptacle 13 carries a fan, such as a tangential fan or, as it is also called, cross-flow fan.
- the receptacle is provided with an outlet opening 15 for the fan and with an inlet opening 16.
- the door device 10 closes a passage 19.
- the door holder 11 is fastened with its one side in some areas to the wall 18 of the passage.
- the inlet opening that is to say the suction opening of the blower 14
- the outlet opening 15 outside the passage 19 lies sideways next to the wing door, so that in front of the Wing door on the outside an air curtain 20 may arise.
- the axis of rotation 24 of the wing door 12 is provided within the receptacle 13 of the door holder 11.
- a sensor 17 is provided at the lower end of the post-like door bracket 1 1. This sensor monitors a defined angular range with respect to the axis of rotation of the swing door. The fan only runs under partial load within this sensor range. Here, the sensor extends from a middle position to both sides of the pivot, as shown in FIGS. 2 and 3.
- the door passage is also monitored via this sensor or other sensors, in such a way that any object lying in the path of movement of the door is determined and leads to the door movement being switched off, and that this sensor serves as an anti-theft device if For example, customers go outside through the passage. Because if these customers carry goods that are not yet exempt from theft protection, they are automatically displayed by an alarm.
- the outlet opening 15 can be formed with a nozzle 21, specifically in order to be able to change the direction of the air curtain jet 20 easily.
- the door device 10 consists of a double sliding door.
- the two sliding doors 23 are guided on the inside 25 of the passage 19, and the range of movement at the door opening could be set by a sensor provided along the movement path. Another sensor is directed towards the passage.
- the door device has a double door, on the side of the door holder 11 facing away from the double door 12, a double pane 26 which carries an air duct 27 in its interior, the double pane 26 extending to the wall 18 of the door Passage 19.
- the air duct is on the one hand on the
- Entry opening 16 of the receptacle is provided. On its other side, it opens into an opening 28 through which air can be sucked or pressed via the air duct 27 into the door holder for receiving 13 and the fan when the fan is actuated (see FIGS. 5 and 6).
- the fan 14 runs at partial load.
- This partial load is used so that when the door is open it is possible to switch to full load without suddenly being able to draw too much electricity from the mains.
- the air duct 27 still has the task of shielding the passage of the door device next to the two door brackets 1 1, in such a way if it is supplied with an air curtain.
- the double-walled glass panes can be used to selectively control cooling or heating, depending on the outside temperature, via the guide channel 27 located between them and taking up the entire pane. Since the intake air comes from the inside, the double pane cools down in summer if this pane is very hot due to solar radiation. In winter it is slightly warmed by the room temperature.
- sensors are also provided in the area of the passage 19 of the door, which determine whether people are approaching the passage or not.
- the door opening can be regulated by means of an automatic control system, so that only one door can possibly be moved so as not to waste energy unnecessarily in winter operation, be it to move the door or to shield the passage.
- the inlet opening for the blower is on the inside 25 of the passage 19, while the outlet opening is on the outside, in order to be able to create an air curtain in front of the door, in this case the air jet is directed somewhat away from the door, so that cold air entering from the outside To catch air better.
- the inlet opening in the interior also ensures that the air curtain on the outside is only moved out of the interior with heated air.
- the air curtain jet from the door bracket 11 covers only half of the passage, that is to say the width of the hinged door or the width of the passage. In the middle, the two beams meet at a double door and form an outward flow.
- the illustrated embodiments are only examples of realizations of the invention. This is not limited to this. On the contrary, there are still many changes possible.
- sensors of different types could be present at different points on the door brackets, and the slot-like outlet opening could also be divided into individual opening sections.
- the adjusting nozzle could possibly be adjusted automatically, depending on, for example, the outside temperature.
- the tangential fan comprises a rotor that has a length that corresponds to the door height.
- the diameter of the rotor is 90 mm or less so that the door bracket is designed to be relatively narrow.
- the outflow angle of the air flow to the closed door is 7 ° away from the door.
- the air flow of the rotor has an exit speed of at least 2m per second.
- the air outlet opening and the air inlet opening of the receptacle are separated from one another, the air inlet opening lying on the side facing away from the door.
