The The invention relates to a ventilation device for ventilation a room, in particular a stable, by a closable space opening the preamble of claim 1.

State of technology

to ventilation a room can be opened in the simplest case, a window or a door, so that fresh air can flow into the room. Here is, however the comparatively poor control or regulation of the incoming fresh air quantity disadvantageous.

So In some cases, this has already been done, the ventilation of a Room, for example, by means of a ventilation system, in particular a fan, room air is sucked out of the room. This creates opposite the atmospheric pressure or the pressure of the outdoor area Negative pressure or a pressure difference between the pressure in the room to Pressure outside of the room. For pressure equalization flows for example by special vents Fresh air into the room.

Rooms with corresponding venting systems point frequently for regulated ventilation Ventilation flaps open through the Negative pressure in the room opened become. flows fresh air into the room, the pressure difference is compensated, so that the correspondingly formed flap the released opening automatically closes again. For this purpose, corresponding fresh air flaps are generally rotatable stored, wherein by means of a counterweight, an automatic closing of the Ensures flap in balanced pressure conditions becomes. In addition to purely mechanical flaps are already flaps with electric Adjustment known.

Embodiment.

One embodiment The invention is illustrated in the drawing and is based on the Figures in more detail below explained.

in the Show individual:

1 a schematic structure, a ventilation device according to the invention as ceiling ventilation,

2 a schematic structure of another ventilation device according to the invention as a wall ventilation,

3 a schematic structure of a third ventilation device according to the invention as a wall ventilation,

4 a schematic structure of the third ventilation device according to the invention as ceiling ventilation,

5 a schematic structure of a fourth ventilation device according to the invention as a wall ventilation and

6 a schematic structure of the fourth ventilation device according to the invention as ceiling ventilation.

In the figures, a total of four different variants of the ventilation device according to the invention are shown as wall and / or ceiling ventilation. These each include a ventilation flap 1 in a housing 2 arranged and about a rotation axis 3 is rotatably mounted.

The ventilation flap 1 can from their resting position 1a in an actuated position 1b be adjusted. Here, the ventilation flap 1 rotates about the axis of rotation 3 , At the same time, it becomes a counterweight 5 adjusted in the vertical direction Y. The counterweight 5 is this over pulleys 6 through a pull rope 4 with the ventilation flap 1 connected.

Advantageously, the housing 2 in the rest position of the ventilation flap 1a largely ge closed, leaving a room to be ventilated or vented 7 separate space 8th inside the case 2 is available. Without closer representation is from the room 7 For example, aspirated by means of a fan or the like room air, so that in the room 7 opposite the gap 8th or the atmosphere sets a differential pressure or negative pressure. Due to the differential pressure between the two rooms 7 . 8th will the ventilation flap 1 from the position 1a in the direction of position 1b adjusted, so that the counterweight 5 through the connecting rope 4 moved up in the direction of Y

According to the in 1 illustrated variant of the invention is in the adjustment of the ventilation flap described above 1 from the position 1a out, next to the counterweight 5 at the same time a closure element 9 or slider 9 adjusted in X-direction. To operate the slider 9 this is with the help of the pull rope 4 and / or a separate, not shown pull rope or the like with the ventilation flap 1 connected or coupled. This is according to 1 a fixation 10 of the slider 9 on the rope 4 intended. By adjusting the ventilation flap 1a in the position 1b becomes the slider 9a in the open position 9b moved, leaving an opening 11 supply air 12 in the room 7 flows in. In the closed position 9a of the slider 9 is the case 2 largely close to the opening 11 locked.

In 1 continues to be a leader 13 shown the slider 9 when actuated by the ventilation flap 1 leads. Alternatively to the guide variant shown, at least in the area of the roller 13 also a rail guide or the like, in particular by means of an angle element, for guiding the slider 9 be provided.

The slider 9 is by means of the role 6 stored in such a way that wind 12 or supply air 12 the slider 9 can not open automatically. The role 6 is thus also designed as a stop element according to the invention.

The ventilation device according to 1 is for a ceiling opening 11 educated. By way of example, the ventilation device is in the corner between a wall 14 and a blanket 15 arranged. Generally, the ceiling can 15 also as a sloping ceiling 15 be formed, wherein advantageously an unspecified adapter element or the like is provided. The adapter element is to be designed such that the slider 9 arranged largely parallel to the direction X or the ventilation flap 1 in closed position 1a in an angular range to the X direction between 60 and 30 degrees, preferably about 40 degrees, is aligned. For example, the ventilation flap 1 a pivoting range of up to about 90 degrees, preferably about 45 degrees.

The in 1 illustrated slide 9 is with the pull rope 4 the ventilation flap 1 connected and opens and closes the supply air intake 11 largely linear with the movement of the ventilation flap 1 , In this variant may optionally be on a back of the case 2 be waived since the wall 14 the housing 2 largely tightly closes. Will the housing 2 from a wall 4 spaced apart, so is generally a rear side of the housing 2 provided.

In the variant of the invention according to 2 is a wing element as a closure element 17 intended. Furthermore, in contrast to the variant according to 1 in the variant according to 2 the opening 11 as a wall opening 11 educated. In this variant, if necessary, on a cover element of the housing 2 be waived, inasmuch as the ceiling 15 the appropriate sealing function for the housing takes over. Is the ventilation device according to the invention, however, from a ceiling 15 spaced apart, so is the housing 2 advantageously provided with a cover element for substantially tight closure of the housing.

The wing 17 is about a rotation axis 18 rotatably mounted and is for example by means of a pull rope 19 with the ventilation flap 1 connected such that an adjustment of the ventilation flap 1 an actuation of the grand piano 17 causes.

In the variant according to 2 points the wing 4 two largely equal wing halves, so that inflowing supply air 12 an automatic adjustment of the wing 17 prevented. To stabilize the equilibrium position or the rest position 17a points the wing 17 a weight 20 on, leaving the wing 17 is arranged largely stable in the Y direction. Alternatively, or in combination with this, the wing 17 be stored eccentrically, so that the stable rest position 17a is guaranteed. In the resting position 17a is the ventilation flap 1a and / or the tow rope 19 as a stop element for the wing 17 formed according to the invention.

For example, the upper wing leg is in the area of the flap tension cable 4 slotted so that this with a corresponding adjustment of the ventilation flap 1 through the wing 17 can pass through. For example, the pull rope runs 4 with the wing closed 17 2 cm deep in the wing 17 , At the flap pull rope 4 there is a driver who has the wing 17 opens in the beginning area.

By adjusting the ventilation flap 1 in the position 1b gets over the tow rope 19 the wing 17 adjusted in the horizontal direction X. In this posi tion is the opening 11 of the room 7 largely open, allowing supply air 12 in the room 7 can flow in.

The in the 3 respectively. 4 illustrated third embodiment is substantially similar to the variant according to 2 built up. The variant of the invention according to 3 respectively. 4 also includes a rotatably mounted wing 17 and one in rest position 17a arranged obliquely to the horizontal axis x ventilation flap 1 , The function of the two embodiments is comparable.

In contrast to the variant according to 2 can the variant of 3 respectively. 4 unchanged as both wall ( 3 ) as well as ceiling ventilation ( 4 ) are used. This universally applicable ventilation unit is for this purpose a little longer or has in the flow direction in front of the wing 17 one compared to the variant of 2 extended vestibule 23 on. The anteroom 23 is designed such that ambient air 12 both for wall or ceiling mounting advantageous to the wing 17 or can flow or flow through the ventilation unit according to the invention.

In addition, between the ventilation flap 1 and the wing 17 according to the variants of 3 respectively. 4 a room air supply or a fan 21 with a cover flap 22 arranged. With the help of the fan 21 can room air in the gap 8th be blown, so that a fresh air, a mixed air or a recirculation mode can be realized. In the fresh air operation of the ventilation unit according to the invention is the fan 21 switched off and a cover flap 22 closes its opening or passage. In this case, essentially only fresh air flows 12 or supply air 12 in the room 7 in the manner already described above.

In mixed air operation, both room air and house air as well as supply air 12 or fresh air 12 conveyed through the ventilation unit, so that mixed air to the ventilation flap 1 flows and from this into the room 7 is steered. In recirculation mode is the wing 17 arranged substantially in the vertical Y-direction, so that no supply air 12 can flow in and only room air through the ventilation unit on the ventilation flap 1 over in the room 7 flows. For the latter case, the adjustment of the wing 17 with the adjustment of the ventilation flap 1 in an advantageous manner and without decoupling detail.

Furthermore, according to 3 and 4 the cover flap 22 designed such that this by the operation of the fan 21 in an advantageous manner in the open position 22b is arranged and at rest 22a the fan 21 or closes its opening. For example, the fan points 21 a housing or sheath which forms the closable opening. As a result, an outflow or a backflow of air from the gap 8th directly through the (switched off) fan 22 through into the room 7 Effectively prevented, so that the air substantially at the ventilation flap 1 over in the room 7 flows. The cover flap 22 thus has a function of preventing so-called kickback. This is especially at negative pressure in the room 7 or in the stable 7 of particular advantage.

The wing 17 is as a deflecting element for in the space 8th incoming room air or formed for fan air. Preferably in a slightly deflected position or in an intermediate position is the wing 17 arranged obliquely to vertical axis Y, so that incoming air in an advantageous manner to the ventilation flap 1 is steered or deflected.

The in the 5 respectively. 6 illustrated fourth, particularly simple and inexpensive embodiment is substantially similar to the variant according to 2 respectively. 3 or 4 built up. The variant of the invention according to 5 respectively. 6 also includes a rotatably mounted wing 17 and one in rest position 17a arranged obliquely to the horizontal axis X ventilation flap 1 , The function of the three embodiments is comparable.

In contrast to the variant according to 2 respectively. 3 . 4 can the variant of 5 respectively. 6 unchanged as both wall ( 5 ) as well as ceiling ventilation ( 6 ) are used. This universally applicable ventilation unit is for this like the according 3 . 4 a little longer or points in the flow direction in front of the wing 17 one compared to the variant of 2 extended vestibule 23 on. The anteroom 23 is designed such that ambient air 12 both for wall or ceiling mounting advantageous to the wing 17 or can flow or flow through the ventilation unit according to the invention.

Furthermore, with the help of one in the 5 . 6 not shown, but comparable to be provided fan 21 a fresh air, a mixed air or a recirculating air operation can be realized.

As an essential difference of the embodiment according to the 5 . 6 over the other embodiments of the 1 to 4 this does not indicate a pull rope 4 or the like attached and deflected weight 5 but a weight 25 on, by means of a lever arm 24 around the axis of rotation 18 is rotatably mounted. This will a particularly simple embodiment of the invention can be realized. The weight 25 can along the lever arm 24 be adjusted or fixed, so that an automatic return of the system in the respective rest position with balanced pressure conditions between the room 7 and the environment outside the room 7 can be achieved. Preferably, the / are the lever arms 25 or weights 25 outside the case 2 or right and / or left (based on the flow direction of the supply air 12 ) from the housing 2 arranged.

In a preferred manner with respect to wall or ceiling ventilation variable usable ventilation unit is provided, for example, a housing having a first recess for the supply of supply air 12 for wall / window mounting and a second recess for the supply of supply air 12 has ceiling mounting. Depending on the application, in each case one of the Rusnehmungen by the ceiling in an advantageous manner 15 or wall 14 and / or closed by means of an exchangeable insert or the like. If appropriate, separate sealing elements can also be used here.

through a corresponding universally applicable ventilation unit according to the invention elevated For example, the number of pieces to be produced, so that a special economical production of the invention can be realized.

Generally this is the counterweight 5 . 25 designed so that this the weight of the ventilation flap 1 , the grand piano 17 including the optional weight 20 , or the friction of the slider 9 at least or slightly more than offsets. As a result, an automatic reset of the system in the respective rest position with balanced pressure conditions between the room 7 and the environment outside the room 7 reached.

The ventilation device shown in the figures is further designed such that in partially open position, the ventilation flap 1 the incoming air 12 towards the ceiling 15 directs. This causes possibly cool air 12 on the relatively warm blanket 15 or in the warm upper area of the room 7 is preheated. This ensures that, for example, animals in stables, especially in intensive animal husbandry, not directly from relatively cold supply air 12 be streamed. Accordingly, a favorable aeration is achieved by means of the device according to the invention.

In addition, with partially opened or pivoted ventilation flap 1 a dynamic pressure in front of the ventilation flap 1 generated essentially by the restoring force of the counterweight 5 is produced. Inflowing air 12 flows along the ventilation flap 1 in a comparatively small intermediate area between the ceiling 15 and the ventilation flap 1 through, so that the air accelerates and especially in cold periods, especially in winter, as long as possible along the ceiling 15 can flow. In the prior art, however, often the cold air with the opening open 11 comparatively slowly in the room 7 flowed in, so that it sinks relatively quickly to the ground and this leads to an impairment, for example, corresponding animals.

In principle, the ventilation device according to the invention can be used as ceiling, wall and / or window ventilation. In this case, an exclusively mechanical adjustment is generally provided, wherein the opening is largely automatic 11 closed or opened without wind influences an uncontrolled opening of the opening 11 can cause. In window mounting, a corresponding adapter element for mounting the ventilation device according to the invention is preferably provided so that it in almost horizontal position according to the 1 and 2 can be arranged.

The housing 2 is generally isolated. Possibly the ventilation device according to the invention, apart from normal cleaning, is generally maintenance-free. Generally, the slide closes 9 or the wing 17 with decreasing negative pressure in the room 7 again the opening 11 ,

For example, at high air flow rate in summer and appropriate arrangement of the ventilation device according to the invention in the room 7 can the air 12 in the room 7 be brought into an advantageous rotational movement, so that especially in stables, the existing heat is better transported away from the animals.

Basically, the windbreak of the ventilation device according to the invention no longer air 12 in the room 7 inflow than is transported away by the ventilation, not shown. This has a positive effect on the room climate, especially in cold outdoor air.
