Ventilation and ventilation device for closed rooms

The invention relates to a ventilation and venting device for closed rooms that each have an opening to the environment and to the room Wall box consists of a motor fan and a muffler.

After installing such wall boxes below or above non-opening windows or on one At other points there is often a desire to switch from ventilation to exhaust ventilation of the room, usually to reduce previously unexpected drafts. In addition, for economic reasons, namely for reasons of production and storage, it is advantageous to design such a wall box so that it is used for both ventilation and ventilation can be used.

Known designs of such wall boxes require a great deal of effort for this.

It is the object of the invention to design such a wall box so that it is in the installed state without removing the motor housing from ventilation operation can be switched to ventilation operation and that only a single construction is required for this is.

This object is achieved according to claim 1 by the design of a ha sondere the suction side from the pressure side of the motor fan separating wall within the wall box. Claims 2 to 5 »6 and 7 indicate three different types of partition wall design, while claims 8 and 9 relate to details that can be used for all possible solutions.

According to claims 2 and 3, the partition with the motor fan attached to it in the wall box with a rotation of 180 ° is designed so that it can be repositioned in a very simple manner so that preferably angled holders come into engagement diagonally with holders arranged in the wall box, the motor fan at its axial Entrance opposite side is fastened by means of a holder on the partition be. Claim 4 gives a solution for this with a motor fan with a right axis perpendicular to the wall box and claim 5 with a diagonal axis.

According to claim 6, the motor fan is on the baffle mounted displaceably from an inlet opening to an adjacent second inlet opening. Due to the special arrangement of a 80 02 07 -3- _,

Leg of the immovable built-in partition between these two inlet openings is the desired reversal of the flow direction in a very simple way.

According to claim 7, this reversal of the flow direction is achieved by two mutually adjustable switching flaps made possible, which are attached in a special way to the immovable built-in partition.

The invention is explained with reference to the drawing with several exemplary embodiments; thereby shows

longitudinal section, namely

Fig. Ha for ventilation and Fig. 4b for ventilation.

The wall box 1 contains at one end an opening 11 leading into the environment, at the other end an opening (not shown) leading to the room and a silencer 12 between them. that is, between this and the muffler, a partition 3 is attached, to which a motor fan 2 is attached by means of a holder k; this need not, as shown in FIGS. 1c and 1d, be designed in the manner of a partition.

According to FIG. 1, the axis of the motor fan is perpendicular to the wall box and diagonally according to FIG. 2, which larger fan diameters permitted and results in better flow conditions. On one to the wall parallel or inclined Trennvandsc'tenkel 3a is each has an inlet opening 3d that is narrowed in the form of a nozzle in the flow direction.

^{Strips 3b 'and 3c 1} or 3a ¹ >> 3t) ¹ and 3c ¹ , which are angled on the partition wall, engage diagonally in holders 5 and 6 arranged in the wall box; these are attached in such a way that the partition wall including the motor fan can be repositioned with a turn of 180. FIGS. 1a and 2a each show the position for ventilation operation and FIGS. 1b and 2b for ventilation operation of the room.

In the first case, the opening 11 serves to suck in fresh air, which is then pressed into the room by the silencer 12, and in the second case to expel stale air which is sucked in from the room by the silencer.

According to FIG. 3, the partition 3 has a leg 3a which is parallel to the wall box 1 and which carries ^{two adjacent fan inlet openings 3d and 3d 1;} a partition wall end limb 3c perpendicular to the wall box extends between these. The other end limb Jb separates the fan chamber from the adjacent silencer 12. The motor fan 2 can be displaced here from one inlet opening to the other, and for this purpose it is either attached to the partition wall or in the wall box, which is not specifically shown. Fig. 3 ^ again shows the ventilation mode in which the fan is connected to the outer inlet opening 3d, while Fig. 3b shows the ventilation mode in which the fan is connected to the inner inlet opening 3d ¹ .

According to FIG. K , the partition 3 with a fan inlet opening 3d is arranged parallel to the wall box and the motor fan 2 is fastened in the wall box with an axis perpendicular to it by means of a holder h, which again does not have to be designed as a partition wall. The adjoining, perpendicular to that side walls are designed as flaps 7 and 8, which are designed to be adjustable between their open position and closed position by means of a linkage and a crank 10.
