Description

ADJUSTABLE VALVE ASSEMBLY FOR AN AIR DUCT IN A VENTILATION
SYSTEM Field of the Invention The present invention relates to an adjustable valve assembly for an air duct for forced or unforced ventilation of a home and the like. The present invention further relates to a mechanical ventilation system comprising at least one air duct and á ventilation device connected to said air duct in which such a valve assembly is provided. Background Many buildings have air ducts which provide passages for exchange, ventilation, circulation and/or movement of air through the surfaces (e.g. walls and ceilings) of the building. Buildings may have ventilation systems, which take in “fresh' air from outside of the building and expel “exhaust” air from inside the building. Fresh air may be taken into a building or exhaust air may be expelled from a building through one or more air ducts. Some buildings incorporate other systems and/or apparatus, such as air conditioning systems, heating systems and bathroom fans, which use air ducts to provide routes for the movement of air through building surfaces. Typically, an air duct is associated with a valve which connects the air duct with a room of the building. A valve provides a passageway in fluid communication with its associated air duct to provide a means for air flow through a building surface. Some valves comprise flow adjustment mechanisms. Such mechanisms allow the flow of air through the valve to be controlled. The valve may comprise a cover for providing a more aesthetically pleasing view of a user.
Object of the Invention An object of the invention is to provide an improved valve, which is manually adjustable when installed in the air duct. Another object of the invention is to provide an assembly of an adjust valve and luminaire body or the like.
Summary of the Invention Aspects of the present disclosure are to address at least the abovementioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a valve assembly for retaining in or mounting to an air duct for ventilation of a house, the air duct may for example end in the floor or ceiling of a room of the house. The valve assembly is furthermore suitable for use with an air duct for supplying air to the room or an air duct for extracting air to the room. The valve assembly comprises an adjustable valve having adjustment means adapted to regulate the flow or pressure of air flowing through the valve, and having an outer housing side adapted to be rigidly connected to said air duct and an inner housing side, opposite the outer housing side, which is arranged to receive said valve. The valve assembly further comprises an electrical body having an electrical connection adapted to connect a power source to an electronic device. Preferably, the body is configured as a luminaire body that is adapted to receive a light source, e.g. a LED, to provide illumination.
The electrical body is adapted to be connected to the adjustment means of the adjustable valve such that axial rotation of the electrical body, i.e. the rotation of the electrical body around its own axis, regulates the flow or pressure of air flowing through the valve. In other words, by turning or rotating the electrical body around its longitudinal axis, the adjustment means adjust the position of the position of flow regulating means of the valve that regulate the flow or pressure of air flowing through the valve, preferably in a predetermined number of discrete steps. In this manner, a user may manually regulate or set the flow or pressure of air flowing through the valve when the valve assembly is installed in the air duct in a simple manner.
According to an embodiment, the present invention relates to the valve assembly as described above, wherein the position of the electrical body, preferably the luminaire body, with respect to the valve and the housing is manually adjustable via point rotation, i.e. via rotation about exactly one rotation point, wherein said rotation point is defined by the connection means between the valve and the body. Advantageously, the direction of the electrical body may be manually adjust to for example adjust the illumination direction in case the electrical body is a luminaire.
According to another embodiment, the present invention relates to the valve assembly as described above, further comprising removable locking means adapted to prevent adjustment of the position of the flow regulating means of the valve.
According to yet another embodiment, the present invention relates to the valve assembly as described above, wherein the valve comprises visual indications on the side that is arranged to face towards a room of the house when the housing is provided in the air duct. According to a further embodiment, the present invention relates to the valve assembly as 5S described above, wherein the adjustable valve is mechanically retained via an annular coil spring. According to a preferred embodiments of the invention, the housing has a diameter of approximately 120 mm and/or a height of approximately 70 mm. In a further aspect the present disclosure is to provide a mechanical ventilation system comprising a ventilation device connected to an air duct in which a valve assembly as described above is provided. Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the present disclosure.

Detailed Description of Embodiments Figures 1 and 2 show a valve assembly 1 for use in an air duct of a mechanical or natural ventilation system of a house or the like. The shown valve assembly 1 comprises an annular housing 40 in which an adjustable valve 10 of the valve assembly 1 is mechanically retained via an annular coil spring 140. The valve assembly 1 further comprises a luminaire 20, 23 connected to and extending from a side of the valve 10 which is arranged to face towards a room of the house, in which the air duct debouches, when the housing 40 1s attached to an inner wall of the air duct. The housing 40 has an outer housing side 41 adapted to be connected to said air duct and an inner housing side 42, opposite the outer housing side 41, which is adapted to be connected to the adjustable valve 10. The valve 10 comprises adjustment means and flow regulating means for regulating the flow or pressure of air flowing through the housing 40 based on the position of the adjustment means. The luminaire 20, 23 comprises a luminaire body 20 adapted to be connected to said adjustment means for adjusting the position of the adjustment means thereby regulating the flow or pressure of air flowing through the housing 40, and arranged towards the room when the housing 40 is attached to an inner wall of the air duct. The proximal end 21 of the luminaire body 20 is adapted to be rotationally connected to the adjustment means such that axial rotation of the luminaire body 20 modifies the position of the adjustment means and point rotation of the luminaire body 20 modifies the direction of the luminaire body B relative to the valve 10 without changing the position of the adjustment means, as shown in Figures 7A and 7B. The distal end 21, opposite the proximal end 22, of the luminaire body 20 is adapted to receive and connect to a light source 23, e.g. a LED, via an electrical connection adapted to be connected to a power source. Furthermore, when in the flow direction the housing 40 is larger than the valve 10, the valve assembly 1 may comprise an annular guide element 30 to guide the air from the end of the housing facing towards a room to the opening in the end of the valve facing towards a room. Similarly to the valve 10, the guide element 30 may be mechanically retained via an annular coil spring 31.
The annular coil springs 140, 141 are adapted to be provided in an annular slot 31, 134 of the valve 10 or guide element 30 to fasten (latch, lock, and hold) the respective part to the housing
40. For example, the coil springs may be compression springs and/or canted coil springs. Advantageously, the coil spring 140, 141 produces a radial or axial force such that the coil spring 5 31, 140 remains in contact with the mating surface and may compensate for large mating tolerances, alignment, and surface irregularities.
Figures 3, 4A-B, 5A-B and 6A-B show an adjustable valve 100 for use in an air duct of a mechanical or natural ventilation system of a house or the like. The adjustable valve 100 comprises a stationary part 130, also called stator, adapted to be stationary connected to said air duct, and a rotatable assembly 110, 120, also called rotor, rotationally connected to said stator
130. The rotatable assembly comprising an inner rotor part 120 and an outer rotor part 110.
As shown in Figures 4A-B, the outer rotor part 110 is formed by an annular outer rotor element 111 connected to a central bowl-shaped element 113 via a plurality of spacers 115, preferably positioned symmetrically around the bowl-shaped element 113, at the upper end of the outer rotor element 111. The outer rotor element 111 comprises a plurality of parallel slots 112 extending from the lower end of the annular element 111 which is arranged to face towards the stator 130, and said slots 112 are preferably positioned symmetrically around the bowl- shaped element 113. The outer rotor element 111 further comprises a plurality of recessed surfaces 116 on its outer surface extending between the subsequent slots 112 in an angular direction and a plurality of corrugated surfaces 117 on the lower end of its outer surface extending between the subsequent slots 112 in the angular direction. In the bowl-shaped element 113 a connection element 114 may be arranged to connect to an electrical body.
As shown in Figures SA-B, the inner rotor part 120 is formed by an annular inner rotor element 121. At upper end of said inner rotor element 124, which is arranged to face towards the outer rotor part 110 and away from the stator 130, the inner rotor part 120 is provided with a ring-shaped element 126 extending inward from the inner surface 122 of the inner rotor element and with a plurality of protrusions 125 on the outer surface 123, opposite the inner surface 122, of the annular element 121. The plurality of protrusions 125 of the inner rotor part 120 and the plurality of parallel slots 112 of the outer rotor part 110 are positioned at corresponding angular positions in the angular direction, preferably arranged symmetrically around the respective annular element. As such, when the inner rotor part 120 is introduced in the outer rotor part 110, each protrusion 125 extends through a respective slot 112 to a widened section of the protrusion 127 provided outside the outer rotor part 110, wherein the width of the widened section of the protrusion 127 is larger than the width of the respective slot 112. Hence, the protrusion 125 will prevent movement of the inner and outer rotor element 111, 121 relative to each other in a plane perpendicular to the axial direction A, e.g. by translation in the radial direction or by rotation in the angular direction.
As shown in Figures 6A-B, the stator 130 is formed by an annular stator element 131 in which an outer slot 134 is provided on the outer surface 133 of the stator element 131 to receive the annular coil spring 140, shown in Figure 3, to mechanically retain the stator 130 in the air duct, and in which at least one inner slot 135 is provided on the inner surface 132 of the stator element 131 to receive and guide the plurality of protrusions 125 of the inner rotor part 120. The at least one inner slot 135 is adapted to guide the plurality of protrusions 125, and thereby axially move the inner rotor part 120, when the plurality of protrusions 125 are rotated around the central axis A. At the lower end of the stator 130, which is arranged to face towards a room of the house, the stator 130 further comprises a ring-shaped element 136. On a lower side of the ring-shaped element 136, the ring-shaped element 136 is provided with visual indications relating to the axial position of the at least one inner slot 135 at a predetermined angular position, and, at the opposite upper side, the ring-shaped element 136 is adapted to receive the lower end of the outer rotor element 111 in an annular recess 137, as shown in Figure 1.
The stator 130 further comprises openings 138a, 138b, of respectively a locking mechanism and a ratchet mechanism, extending axially from the lower end of the stator element 131 to allow insertion of a complementary element by a user when installed and extending radially the inner surface 132 to allow interaction between the complementary element and the outer surface of the outer rotor element 111.
By introduction of locking means 150 in the opening 138a, the locking means 150 interact with the corrugated surface 117 of the outer rotor part 110 to lock the relative position between the stator 130 and the rotor parts 110, 120. By introduction of ratchet means 160 in the opening 138b, the ratchet means 150 interact with the corrugated surface 117 of the outer rotor part 110 to limit the rotational movement between the stator 130 and the rotor parts 110, 120 to clockwise or counterclockwise movement in the angular direction.
The stator element 131 further comprises a plurality of countersunk or counterbored holes 139 on its outer surface to receive a respective screw or the like 170 that extends in a respective recessed surface 116 of the outer rotor element 111 to mechanically retain the outer rotor part 110, and thereby also the inner rotor part 120, inside the annular stator element 131, i.e. in the space defined by the annular stator element 131 and the lower ring 136. The screw 170 and recesses 116 further limit the rotational movement of the outer rotor part 110 in the angular direction. Next, the operating principle of the valve of the present invention will be described. As mentioned above the valve 10, 100 comprises adjustment means and flow regulating means for regulating the flow or pressure of air flowing through the valve 10, 100. The adjustment means comprises the bowl-shaped element 113, optionally attached to the proximal end 21, that are rigidly connected to the outer rotor element 111. By turning the bowl- shaped element 113, the position of the valve 10, 100 may be changed towards the closed position or towards the open position depending on the direction of rotation. Turning of the bowl-shaped element 113 causes the outer rotor element 111 to tum in the same direction of rotation, and therewith the protrusions 125 of the inner rotor element 121 present in the slots of the outer rotor element 112. The protrusions 125, extending through the slots of the outer rotor element 112 and received in the at least one inner slot 135 of the stator element 131, are guided by the at least one inner slot 135 when turning the bowl-shaped element 113. Due to the fact that the at least one inner slot 135 extends in the axial direction A, the axial position of the guided protrusions 125 change relative the stator 130 and the outer rotor part 110. Because of that the axial position of the ring- shaped element 126 of the inner rotor part 110 is changed relative to the bowl-shaped element
113. Hence, the flow or pressure of air flowing through the valve 10, 100 is adjusted because the air passage through the valve is defined by the space between the bowl-shaped element 113 and the ring-shaped element 126. The flow rate is increased by turning the bowl-shaped element 113 clockwise and the flow rate is decreased by turning the bowl-shaped element 113 clockwise, or vice versa. Other alternatives and equivalent embodiments of the present invention are conceivable within the idea of the invention, as will be clear to the person skilled in the art. The scope of the invention is limited only by the appended claims.
