Description

Technical field

[0001] The present disclosure relates to the technical field of HVAC systems, and more particularly to a cover for an inner module of a HVAC system.Background

[0002] HVAC systems are increasingly used as a heating and cooling system in households, due to their energy efficiency and sustainability, compared to their more energy-intense counterparts, for example gas burners or furnaces. HVAC systems include heat pumps, air conditioners, ventilation systems, etc., and are typically comprised by two major components, an exterior unit installed outside of the building, and an indoor unit installed inside the building. The indoor unit is not always pleasing to the eye, and it may impair the ambience in a room. Looking at heat pumps for example, although they are energy efficient, some people opt out from using heat pumps due to their appearance and their (negative) effect on the indoor environment. There are currently limited possibilities for end consumers to influence the appearance of the heat pumps or other HVAC system themselves, which may also play a part in the decision to opt out from these types of products.

[0003] To increase the demand for HVAC systems, for example heat pumps or air conditioners, the design of the indoor and outdoor units as well as additional components may be improved.Summary

[0004] The term "HVAC system" is a term used to explain a system that either heats, ventilates, or air conditions an enclosed space, such as a house. These operations may be performed by individual systems, or by a combined system that has the capability to, for example, both heat and cool a space. Almost all operations include some type of exchange or replacement of air inside the enclosed space to the environment outside of the enclosed space, and therefore the system, irrespective of the operation to be performed, typically consists of two major components, an indoor unit and an outdoor unit. In some examples the HVAC system may also include an indoor radiator, in which case there may only be an indoor unit.

[0005] The indoor unit, or 'inner module' herein means the unit installed inside of the building where the HVAC system is installed. The inner module is preferably placed near an exterior wall, where the outdoor unit is placed on the opposite side of the same exterior wall. Since the inner module and the outdoor unit are coupled to each other, for example by conduits transporting air between the modules or cooling / heating air by use of a heat exchanger, the two units should not be placed too far from each other, since that may impair the efficiency of the system. The possible placements of the inner module are therefore limited. The inner module may come in different sizes and shapes, and the shape and / or size may vary depending on the size of the building, the HVAC system provider, etc. In one example, the inner module may have a substantially rectangular shape, with a height, a width, and a depth. The height may be smaller than the width, in an installed position. Further, the indoor module may be mounted on the wall or placed on a floor close to the wall. The conduits coupling the inner module and the outdoor unit may be drawn through the exterior wall, for example.

[0006] Due to the restricted placements of the inner module, an end user or consumer of the HVAC system may have to install the inner module in an undesired place in their house, resulting in them feeling displeased with the installation. Some people spend a lot of time and energy on decorating their homes, why the inner module may ruin the thought behind the interior design in a room. Further, the inner module may have to be installed in a position where it is difficult to avoid it, e.g., where it is difficult to avoid things bumping into it. Even further, the HVAC system, while working, may generate a noise which may disturb people present in the same room.

[0007] In the light of the above, it is desired to provide alternate solutions for improving the indoor environment where a HVAC system is installed. These and other objects are achieved by providing a cover for an inner module of a HVAC system having the features in the independent claims. Preferred embodiments are defined in the dependent claims.

[0008] Hence, according to a first aspect of the present invention, there is provided a cover for an inner module of a heating, ventilation or air conditioning system, comprising a screen intended to at least partially enclose the inner module of the system, and a frame arranged on inner surface of the screen facing the inner module of the system. The frame comprises at least one hanger intended to be mounted on an outer surface of the inner module of the system or on a wall adjacent the inner module, and configured to support the screen in a position adjustable in a height direction relative the inner module of the system. The cover may therefore provide a way to conceal the inner module of the HVAC system, such that its unpleasing appearance is hid from the eye of the beholder. Further, the cover may function as protection and prevent damages to the inner module due to things bumping into it. Even further, the cover may have soundproofing properties such that the noise generated from the inner module may be less disturbing.

[0009] According to an exemplifying embodiment of the present disclosure, the screen comprises a front surface, and a first and a second side surface, wherein the first side surface and the second side surface are arranged opposite to each other, and connected via the front surface extending between the first side surface and the second side surface, to enclose a front surface and two side surfaces of the inner module of the HVAC system. The screen may enclose one or more surfaces of the inner module.

[0010] In one example, the inner module may be installed on a floor adjacent to a wall and have a substantially rectangular shape. The screen may then enclose the inner module by having a wall extending in a vertical direction, i.e., the 'height' direction of the inner module, covering the surface of the inner module opposite to the surface facing the wall, i.e., the 'front surface'. The screen may further enclose the inner module by having two walls extending in a vertical direction covering a side surface on each respective side of the front surface. The bottom surface of the inner module, facing the floor, and the top surface of the inner module opposite to the bottom side, may be free from coverage. This is advantageous in that since most HVAC systems operate by exchanging air between the indoor environment and the outdoor environment, and therefore a fully covered inner module may prevent air from being properly distributed from or drawn into the inner module. It may further be advantageous to enclose the surfaces of the inner module having the largest area of the surfaces, and in that way enclosing an area as large as possible of the inner module without impairing the air distribution and / or extraction. Covering a larger area of the inner module means concealing a larger area of the inner module, which may be desirable. Further, the inlet and / or outlet for air from the inner module may be located on a top side, for example, why it may be desired to avoid covering or enclosing that side. In another example, the top surface and the front surface of the inner module may be covered by the screen, but not the side surfaces, for example.

[0011] In a further example, the inner module may be installed hanging from the ceiling, and the screen may then enclose a bottom surface, i.e., the surface opposite to the surface facing the ceiling, and some or each of the four side surfaces.

[0012] According to an exemplifying embodiment of the present disclosure, the screen comprises a sheet of material, and wherein the front surface, and the two side surfaces are formed by bending. The screen may therefore be formed by one part and bent into the desired shape. For example, the screen may have a u-shaped profile to cover the front surface and the side surfaces. The screen may comprise one sheet of material, or a two or more sheets of layered materials. For example, the outer surface of the screen facing the indoor environment may be comprised by a first sheet of material, and the inner surface of the screen facing the inner module may be comprised by a second sheet of material. The first sheet and the second sheet may be made from the same material, or from different materials. The first and second layer may be attached to each other with an adhesive, a laminate, sewn, or pressed, for example. The screen may for example be made from a wooden material, such as plywood, felt, textile, glass, metal, a cellulose based material or a plastic, such as acrylic glass, for example. Moreover, the screen may be made from a composite material, such as a carbon fiber. In other examples, the screen may have a first sheet comprising a stoneware, such as marble or granite. In the example where more than one sheets of material is used, the first sheet of material may be a wooden material, and the second sheet of material may be felt, or vice versa. For example, felt may be advantageous since it has soundproofing properties. Moreover, a wooden material may be more aesthetically pleasing. In one example, the screen is replaceable, and a user may choose from a range of different screens. Therefore, the cover may be adapted according to the preferences of the end user, so that they may adapt it to fit in with the interior design in the space where the inner module is intended to be installed. The cover may thus advantageously provide an aesthetically pleasing cover for an inner module of a HVAC system, for example a heat pump.

[0013] A further advantage with the screen being formed by bending is that the screen may be packaged and transported in a flat package. In one exemplifying embodiment of the present disclosure, the screen may be bendable. A bending portion may be prepared on the screen during manufacturing, enabling the screen to be bent. The bending portion may for example be a treatment of the screen, for example cutting the material and forming a bending or folding seam, to allow it to be bent or folded. The screen may then be transported to the customer or user in a flat state, whereafter the consumer or user bends or folds the screen into the desired and / or final shape. This is advantageous in that the cover may be transported in a space-efficient way, which is beneficial for the environment, and the carrier.

[0014] To arrange the screen in a position where it at least partially encloses the inner module, there is a frame arranged on an inner surface of the screen, i.e., the surface of the screen facing the inner module. The frame may provide structural support to the screen, as well as it may provide means for mounting the screen in an intended position, at least partially enclosing the inner module. According to an exemplifying embodiment of the present disclosure, the frame comprises at least one tube intended to extend along the side of the screen facing the inner module of the heat pump, and wherein the at least one tube is bent to form a shape corresponding to a desired shape of the inner surface of the screen. The frame may be a metal wire or a metal tube, for example. In some examples, the frame may be made from a hollow tube, allowing cables or other types of conduits to be drawn through the frame. The frame may follow the shape of the screen. Therefore, if the screen has a u-shaped profile, the frame may have a corresponding u-shaped profile.

[0015] According to an exemplifying embodiment of the present disclosure, the frame comprises two separate parts, a first part arranged on an upper portion of the screen and supported by the at least one hanger, and a second part arranged on a lower portion of the screen. The first part and the second part of the frame may both be formed by a tube or a wire. In one example, the first part and the second part are identical. The first part may be arranged on an upper portion of the screen, in a height direction thereof. Correspondingly, the second part may be arranged on a lower portion of the screen, in a height direction thereof. The first part and the second part may be advantageously distributed along the height of the screen to provide structural support to the screen.

[0016] According to an exemplifying embodiment of the present disclosure, the cover further comprises at least one gripping means arranged on the inner surface of the screen and configured to removably attach the frame to the screen. The frame may be attached to the screen in a removable manner, such that the screen may be exchanged without the need to exchange the frame or other components. This is advantageous since it facilitates the use of the cover and enables an end user to exchange the screen according to their needs or preferences.

[0017] According to an exemplifying embodiment of the present disclosure, the at least one gripping means is a clip. The clip may be attached to the inner surface of the screen with an adhesive, or a fastener such as nails, screws, nuts or bolts. Further, the clip may be configured to receive the frame and hold it in place by clamping around the frame. In the example where the frame is a type of tubular element, the clip may have a diameter corresponding to that of the tubular element, but with an opening having a slightly smaller diameter, such that, when received, the frame is prevented from detach from the clip. The clip may be made from a partially flexible material, such that the frame may be pushed into the opening of the clip. The partially flexible material may for example be a type of plastic.

[0018] The screen is supported by the at least one hanger in a position adjustable in a height direction relative the inner module of the system. The screen may therefore be mounted on the at least one hanger. The at least one hanger is mounted on an outer surface of the inner module of the system or on a wall adjacent the inner module. The outer surface of the inner module may be any one of the beforementioned surfaces of the inner module, for example the front surface, side surfaces, top surface or bottom surface. The wall adjacent the inner module may be the exterior wall against which the inner module may be installed. According to an exemplifying embodiment of the present disclosure, the at least one hanger is attached to the inner module or the wall adjacent the inner module with an adhesive. The at least one hanger may further be attached to the inner module or the wall adjacent the inner module with screws, or with both an adhesive and screws. The at least one hanger may therefore be fixed on the inner module or on the wall adjacent the inner module. The screen may be adjustable in a height direction by adjusting the height of the screen relative the fixed position of the at least one hanger.

[0019] According to an exemplifying embodiment of the present disclosure, the at least one hanger comprises a first part and a second part, wherein the first part is slidably arranged in a substantially vertical direction in the second part, and wherein the second part comprises a locking means configured to lock the first part in an intended position inserted in the second part. The second part of the at least one hanger may be attached to the inner module or the wall adjacent the inner module. The first part may not be fixed nor attached to the inner module or the wall. Instead, the first part is coupled to the second part by being slidably arranged in the second part in a vertical direction, such that the first part may move in a height direction relative the second, attached, part. The substantially vertical direction may correspond to the height direction of the inner module and the screen. Moreover, the locking means may secure the first part in the intended position relative the second part. This is advantageous in that it allows the first part to be adjustable in a height direction relative the second part of the hanger, which may be in a fixed position. Since the at least one hanger supports the frame and the screen, this means that the screen may be adjustable in a height direction relative the inner module. This is particularly advantageous since it enables the screen to be adjustable in relation to the inner module, meaning that the screen may be adapted to the installation position of the inner module. An end user installing the cover may therefore not be limited by the installation position of the inner module but may instead adapt the cover to correspond to that position. The height of the inner module may alter depending on the provider, the preferences of the user or the conditions in the building where it is installed. Therefore, it is important that the cover may be adapted to work for more than one type of inner module, and more than one height.

[0020] According to an exemplifying embodiment of the present disclosure, the locking means comprises a plurality of teeth configured to engage with corresponding teeth arranged on the first part, in a male / female configuration. The second part may comprise a groove in which the first part may be slidable arranged in. The groove may comprise a plurality of teeth for locking the first part in the intended position. The teeth may function as barbs and have a shape corresponding to that of an end portion of the first part. Therefore, when the first part is slidably inserted into the groove of the second part, the first part may easily slide in one direction, but when trying to withdraw the first part from the groove, the teeth prevent the first part from being extracted, therefore functioning as barbs. The plurality of teeth may be distributed along a length of the second part and correspond to different levels of height. The adjustable height may range between 0 and 20 centimeters, for example.

[0021] According to an exemplifying embodiment of the present disclosure, the at least one hanger comprises a u-shaped support configured to receive the frame. The frame may therefore be hung on the u-shaped support on the at least one hanger. This is advantageous in that the screen may easily be mounted on the at least one hanger, which facilitates the installation for the user. Further, the screen may easily be lifted off the at least one hanger and thereby uncover the inner module, facilitating the replacement of the cover or removal of it. According to an exemplifying embodiment of the present disclosure, the u-shaped support is arranged on the first part of the at least one hanger. The frame may therefore be hung on the part of the at least one hanger that may be adjusted in a height direction, allowing the screen to be adjusted in a height direction.

[0022] According to an exemplifying embodiment of the present disclosure, the at least one hanger is two hangers arranged at different positions on the inner module or the wall adjacent the inner module. The two hangers may for example be positioned on each of the side surfaces of the inner module, or on two respective sides in a horizontal direction of the inner module. Having more than one hanger is advantageous since it distributes the weight of the screen on the two hangers and increases the stability of the arrangement. It further enables the screen to be hanged in a balanced position, not being skewed in a horizontal direction relative the inner module or the wall.

[0023] According to an exemplifying embodiment of the present disclosure, the cover further comprising an adjustable wall support arranged at an end portion of the frame, and configured to support the screen in a position adjustable in a depth direction relative the inner module of the heat pump and to rest against a wall adjacent the inner module of the heat pump. The frame may have an end portion arranged adjacent the wall, in an installed position. In the example where the frame is a tubular element, the end portion may be an end portion of the tubular element. The wall support may be an additional component mounted on the end portion of the frame. In one example, the wall support is a type of stopper with an adjustable length. The stopper may be threaded onto the end portion of the frame. The stopper may therefore comprise a recess or a hole such that it may be sleeved around the end portion of the frame. The wall support may be available in different lengths, such that the screen may be installed with a distance to the inner module and / or with a distance to the wall adjacent the inner module. The wall support lets some of the weight of the screen to rest against the wall. Further, the wall support and the at least one hanger both carry the screen and the frame to install them into a desired position. The wall support supports the screen in a horizontal direction, while the at least one hanger supports the screen in a vertical direction.

[0024] It may be important to maintain a distance between the cover and the inner module, and / or the wall adjacent the inner module, to allow air to circulate around the inner module. Another reason to maintain a distance between the cover and the inner module may be to allow for cable routing. Some HVAC systems require a number of cables to be drawn to and / or from the inner module. In some cases, the cables may consume a significant amount of space around the inner module. Thus, it may be desired to conceal the cables as well as the inner module, and therefore the cover may be arranged at a distance from the inner module, such that the cables fit within the cover. The wall support may comprise one or more stoppers, forming the wall support. The one or more stoppers may be connected to each other, for example by being threaded onto each other, and onto the end portion of the frame, such that a user may remove or attach a stopper to the wall support, to thereby adjust the distance between the screen and the wall. The one or more stoppers may also come in individual sizes or lengths, such that a user may choose the stopper suitable for their installation. In this example, the stoppers may be attached to the end portion of the frame individually. In a further example, the one or more stoppers may be one stopper threaded onto the end portion, and wherein the whole length of the stopper is threaded, such that the distance may be adjusted by threading the stopper a desired length onto the end portion. The one or more stoppers may also be arranged in a telescopic arrangement, either by itself or connected to each other, to enable adjustment of the length.

[0025] The present embodiment is advantageous in that it increases the modularity of the cover and allows the user to adapt the cover to the conditions of their HVAC system installation. The wall support is further advantageous in that it prevents the frame from leaving a mark on the wall, which may be difficult to get rid of. The wall support may thereby function as a cushion or a padding for the frame, which further has the advantage of preventing the frame from sliding against the wall. The wall support may for example be made from a material such as rubber, a thermoplastic, felt, or a wooden material or a combination of materials.Brief description of the drawings

[0026] Exemplifying embodiments will now be described in more detail, with reference to the following appended drawings, in which: Figure 1 illustrates a perspective view of a cover according to an exemplifying embodiment of the present disclosure; Figure 2 illustrates a perspective view of a cover installed around an inner module of a HVAC system according to an exemplifying embodiment of the present disclosure; Figure 3 illustrates a front view of a cover according to an exemplifying embodiment of the present disclosure; Figure 4 illustrates a top view of the cover according to an exemplifying embodiment of the present disclosure; Figures 5a-d illustrates different views of a hanger according to an exemplifying embodiment of the present disclosure; Figure 6 illustrates a perspective view of a gripping means according to an exemplifying embodiment of the present disclosure. Detailed description

[0027] As illustrated in the figures, the size of the elements and regions may be exaggerated for illustrative purposes and, thus, are provided to illustrate the general structures of the embodiments. Like reference numerals refer to like elements throughout.

[0028] Exemplifying embodiments will now be described more fully hereinafter with reference to the accompanying figures, in which currently preferred embodiments are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the invention to the skilled person.

[0029] With reference to figure 1, a perspective view of a cover 100 according to an exemplifying embodiment of the present disclosure is shown. The cover 100 has a width w, a height h and a depth d. The width w is greater than the height h. The cover 100 comprises a screen 110 and a frame 120. The screen 110 is formed from a bent sheet of material, and the bent portions 115 are seen forming two corners 115 on the screen 110. The screen 110 forms a u-shape with three sides, a longer side a and two shorter, opposite sides b, c. The bent portion 115 may be bent with an angle α. The angle α may range between 80 to 150 degrees, for example.

[0030] The screen 110 has an inner surface 111 on which the frame 120 is attached. The frame 120 comprises two parts, a first part 120a, and a second part 120b. The first part 120a is arranged on an upper portion 110a of the screen 110, and the second part 120b is arranged on a lower portion 110b of the screen 110. The first part 120a and the second part 120b are thus separated from each other with a distance along the height direction h of the cover 100. The frame 120 is comprised by a wire or a tube with a substantially circular cross-section. The frame 120 is attached to the screen 110 with clips 170. There are a number of clips 170 distributed horizontally along the screen 110, on all sides a, b, c. The clips 170 clamps the frame 120 such that the frame is attached to the screen 110. The clips 170 may be attached to the screen with an adhesive or via fasteners, for example. The second part 120b of the frame 120 comprises a wall support 160 attached to an end portion 122 thereof. The wall support 160 is intended to rest against a wall (not visible) adjacent to the inner module (not visible) around which the cover 100 is installed. The wall support forms a partial sleeve around the end portion 122 of the second part 120b of the frame. The first part 120a of the frame 120 rests on a pair of hangers 130a, 130b. The hangers 130a, 130b are attached to the inner module (not shown). The hangers 130a, 130b are arranged towards the shorter opposite sides b and c of the screen 110. The hangers 130a, 130b each comprise a u-shaped support 131 configured to receive the first part 120a of the frame 120. The u-shaped support 131 prevents the first part 120a of the frame 120 from falling off or being detached from the hangers 130a, 130b. The screen 110 has three larger faces, or 'surfaces', facing the indoor environment where the cover 100 is installed. There is a front surface (not visible) opposite to the inner surface 111, a first side surface 113, and a second side surface (not visible).

[0031] The cover 100 is seen installed around an inner module 200 of a HVAC system in figure 2. In other words, figure 2 illustrates the cover 100 installed in an indoor environment, partially enclosing an inner module 200. The inner module 200 may be attached to the wall 300, as illustrated in the figure. In other examples, the inner module 200 may stand on a floor (not visible) against or adjacent the wall 300. The HVAC system may also include floor and / or wall mounted radiators. In the example shown in figure 2, the inner module 200 may be part of an air conditioning system. The screen 110 is illustrated with dotted lines. The front surface 112 of the screen 110 is facing the indoor environment surrounding the inner module 200. The inner surface (not visible) of the screen 110 is facing the inner module 200. The screen 110 further comprises a first side surface 113 and a second side surface 114 facing the indoor environment. The longer side a and the two shorter, opposite, sides b, c together encloses parts of the inner module 200. The shape of the screen 110 corresponds to the shape of the inner module 200, for example, the bent portions 115 of the screen coincides with the corners 215 of the inner module 200.

[0032] The holder 130 visible in figure 2 is attached to an outer surface 210 of the inner module 200. In the example shown in the figure the holder 130 is attached to one of the shorter side surfaces (which forms part of the outer surface 210) of the inner module 200. The holder 130 may be attached to the inner module 200 with a type of adhesive, for example. Thereby, no modification to the inner module 200 is required to install the cover 100 around the inner module 200. The first part 120a of the frame 120 is supported by the u-shaped support 131 on the hanger 130. The cover 100 is thereby supported in a vertical direction by the holder 130 together with the inner module 200. The installation position of the screen 110 can be adjusted with the holder 130. By raising or lowering the screen 110 relative a height direction of the inner module 200, the position of the screen 110 may be adjusted to coincide with the position of the inner module 200.

[0033] The second part of the frame 120b has an end portion 122, where a wall support 160 is attached. The wall support 160 rests against the wall 300, and thereby supports the cover 100 in a horizontal direction. The wall support 160 is adjustable in a depth direction relative the depth of the inner module 200. The position of the screen 110 may therefore be adjusted and adapted to a depth of the inner module 200 around which it is installed.

[0034] Moreover, the cover 100 may be mounted entirely on the inner module 200, why no modification to the wall which it rests against is required. This is advantageous in that it facilitates the installation of the cover 100, where no tools are required, while avoiding making any interventions on the wall, such as bore holes.

[0035] With reference to figure 3, a front view of a cover 100 according to an exemplifying embodiment of the present disclosure is shown. The outer surface of the screen 110 comprised by the front surface 112, the first side surface 113 and the second side surface 114, as well as the bent portions 115, has a smooth, flat finish. The screen 110 is made from a sheet of material that is bent to achieve the finishing shape. The sheet of material may for example be a wooden material, a felt material, a metal, a textile, a stoneware, a composite, a ceramic material, a plastic, etc. Moreover, the screen 110 may be made from one or more layers of a sheet of material. For example, the inner surface (not visible) may be comprised by one sheet of material, and the outer surface may be formed from a second sheet of material. In another example, the user may choose the finish of the screen 110. The user may for example choose to paint the outer surface of the screen 110 or choose a type of wood matching with other furniture in the indoor environment where the cover 100 is installed. The front surface 112 of the screen 110 has a top end 112a and a bottom end 112b. The top end 112a, in an installed position, is arranged to coincide with a top end of the inner module 200, and the bottom end 112b is arranged to coincide with a bottom end of the inner module 200.

[0036] With reference to figure 4, a top view of the cover 100 according to an exemplifying embodiment of the present disclosure is shown. The inner module 200 is not visible in the present figure. Instead, there is shown a space 200a formed between the wall 300 and the cover 100 when the cover 100 is installed. The inner module 200 fits in the space 200a. The figure illustrates the cover 100 from a top view, meaning that it is shown from the top end 112a of the front surface of the screen 110. The wall support 160 comprises three parts, a first part 160a, a second part 160b and a third part 160c. The first, second and third parts 160a, 160b, 160c are attached to each other to form the wall support 160. However, the first, second and third part 160a, 160b, 160c of the wall support 160 are detachable from each other, such that the distance along a horizontal direction between the wall 300 and the front surface 112 of the screen 110 may be adjusted. The third part 160c of the wall support 160 may for example, be detached from the second part 160b of the wall support 160, leaving the first part 160a and the second part 160b forming the wall support 160. In another example, the third part 160c and the second part 160b of the wall support 160 are detached from the first part 160a. In yet another example, only the second part 160b of the wall support 160 is detached. In this way, a user may adjust the distance between the wall 300 and the front surface 112 of the screen 110 according to their own preferences. In a further example, the first part 160a, the second part 160b, and the third part 160c may be individual and separate parts with different lengths. The user may receive all parts, and thereafter choose which one of the first part 160a, the second part 160b and the third part 160c that suits their installation best. In yet a further example, the wall support 160 may be formed by one single piece, threaded onto the end portion 122. The distance may, in this case, be adjusted by threading the wall support 160 a desired length onto the end portion 122. Alternatively, wall support 160 is attached to the end portion 122 and adjusted by the means of a telescopic arrangement.

[0037] With reference to figure 5a, a perspective view of a hanger 130 according to an exemplifying embodiment of the present disclosure is shown. The hanger 130 comprises a first part 140 and a second part 150. The first part 140 is slidably arranged in the second part 150 via a groove (not visible) in the second part 150. The first part 140 comprises a grip 141 for a user to grip a hold of to adjust the height of the screen 110 relative the inner module 200. The grip 141 may have a shape that fits a fingertip, such that a user may easily grip and hold the grip 141 while adjusting the height. The first part 140 of the holder 130 further comprises a u-shaped support 131 to receive and support the frame 120. The u-shaped support 131 has a shape corresponding to a shape of the frame 120. For example, if the frame 120 is a tube with a circular cross-section, the u-shaped support 131 may have a rounded u-shape for receiving the frame 120.

[0038] With reference to figures 5b and 5c, the hanger 130 is shown in having its maximum adjustment height. The first part 140 is slid out from the groove 153 of the second part 150 as much as possible, in a direction illustrated by an arrow in the figure. The grip 141 functions as a stopper, preventing the first part 140 from detaching completely from the second part 150. The second part 150 comprises a front portion 154, also preventing the first part 140 from falling out from the groove 153. In figure 5c, the second part 150 is shown without the front portion 154. The second part 150 comprises a locking means 151, for locking the first part 140 in an intended position in the second part 150. The locking means 151 comprises a plurality of teeth 152, arranged along the sides of the second part 150. The teeth 152 secures the first part 140 in a desired position within the groove 153. The first part 140 comprises a mating portion, or a corresponding tooth 142, fitting into the teeth 152 in a male / female configuration. When the tooth 142 is engaged with a set of teeth 152, the first part 140 is thereby prevented from being slid out from that position in the direction of the arrow, or in the opposite direction. To disengage, and 'unlock' the first part 140, for example if the height needs adjusting, the user may push the two grips 141 towards each other, to detach the tooth 142 of the first part 140 from the set of teeth 152 of the second part 150. While pushing the two grips 141 towards each other, the first part 140 may be slid up and down in the groove 153, until a desired height is reached. Thereafter, the two grips 142 may be released and the first part 140 locked in the groove 153 in the desired position.

[0039] Figure 5d shows the rear part 155 of the holder 130, being attached to the inner module (not visible). The rear part 155 has a smooth, flat surface, to correspond to a smooth, flat surface of the inner module where it should be attached.

[0040] With reference to figure 6, a perspective view of a gripping means 170 according to an exemplifying embodiment of the present disclosure is shown. The gripping means 170 is a clip, comprising two clamps 171 arranged thereon, and configured to receive the frame 120. Through-holes 175 are arranged around the clamps 171, releasing the pressure on the clip 170 when the frame 120 is inserted. When the frame 120 is inserted into the clamps 171, the clamps 171 will be momentarily deformed by the force from the frame 120 being pushed into the clamps 171. This force may propagate into the remaining area of the clip 170, in the long-term causing fatigue. The through-holes 175 prevent this from happening since they are able to absorb the force and reduces the deformation from the clamps 171.

[0041] Further, the clip 170 may be attached to the inner surface (not visible) of the screen (not visible) via screws 173 screwed through bore holes 172 in the clip 170. The clip 170 may further be attached to the inner surface with an adhesive, or with a combination of an adhesive and screws 173.

[0042] Although features and elements are described above in particular combinations, each feature or element can be used alone without the other features and elements or in various combinations with or without other features or elements.

[0043] Additionally, variations to the disclosed embodiments can be understood and effected by the skilled person in practicing the claimed invention, from a study of the figures, the disclosure, and the appended claims. In the claims, the word "comprising" does not exclude other elements, and the indefinite article "a" or "an" does not exclude a plurality. The mere fact that certain features are recited in mutually different dependent claims does not indicate that a combination of these features cannot be used to advantage.

Technical field

[0001] The present disclosure relates to the technical field of HVAC systems, and more particularly to a cover for an inner module of a HVAC system.Background

[0002] HVAC systems are increasingly used as a heating and cooling system in households, due to their energy efficiency and sustainability, compared to their more energy-intense counterparts, for example gas burners or furnaces. HVAC systems include heat pumps, air conditioners, ventilation systems, etc., and are typically comprised by two major components, an exterior unit installed outside of the building, and an indoor unit installed inside the building. The indoor unit is not always pleasing to the eye, and it may impair the ambience in a room. Looking at heat pumps for example, although they are energy efficient, some people opt out from using heat pumps due to their appearance and their (negative) effect on the indoor environment. There are currently limited possibilities for end consumers to influence the appearance of the heat pumps or other HVAC system themselves, which may also play a part in the decision to opt out from these types of products.

[0003] To increase the demand for HVAC systems, for example heat pumps or air conditioners, the design of the indoor and outdoor units as well as additional components may be improved.Summary

[0004] The term "HVAC system" is a term used to explain a system that either heats, ventilates, or air conditions an enclosed space, such as a house. These operations may be performed by individual systems, or by a combined system that has the capability to, for example, both heat and cool a space. Almost all operations include some type of exchange or replacement of air inside the enclosed space to the environment outside of the enclosed space, and therefore the system, irrespective of the operation to be performed, typically consists of two major components, an indoor unit and an outdoor unit. In some examples the HVAC system may also include an indoor radiator, in which case there may only be an indoor unit.

[0005] The indoor unit, or 'inner module' herein means the unit installed inside of the building where the HVAC system is installed. The inner module is preferably placed near an exterior wall, where the outdoor unit is placed on the opposite side of the same exterior wall. Since the inner module and the outdoor unit are coupled to each other, for example by conduits transporting air between the modules or cooling / heating air by use of a heat exchanger, the two units should not be placed too far from each other, since that may impair the efficiency of the system. The possible placements of the inner module are therefore limited. The inner module may come in different sizes and shapes, and the shape and / or size may vary depending on the size of the building, the HVAC system provider, etc. In one example, the inner module may have a substantially rectangular shape, with a height, a width, and a depth. The height may be smaller than the width, in an installed position. Further, the indoor module may be mounted on the wall or placed on a floor close to the wall. The conduits coupling the inner module and the outdoor unit may be drawn through the exterior wall, for example.

[0006] Due to the restricted placements of the inner module, an end user or consumer of the HVAC system may have to install the inner module in an undesired place in their house, resulting in them feeling displeased with the installation. Some people spend a lot of time and energy on decorating their homes, why the inner module may ruin the thought behind the interior design in a room. Further, the inner module may have to be installed in a position where it is difficult to avoid it, e.g., where it is difficult to avoid things bumping into it. Even further, the HVAC system, while working, may generate a noise which may disturb people present in the same room.

[0007] In the light of the above, it is desired to provide alternate solutions for improving the indoor environment where a HVAC system is installed. These and other objects are achieved by providing a cover for an inner module of a HVAC system having the features in the independent claims. Preferred embodiments are defined in the dependent claims.

[0008] Hence, according to a first aspect of the present invention, there is provided a cover for an inner module of a heating, ventilation or air conditioning system, comprising a screen intended to at least partially enclose the inner module of the system, and a frame arranged on inner surface of the screen facing the inner module of the system. The frame comprises at least one hanger intended to be mounted on an outer surface of the inner module of the system or on a wall adjacent the inner module, and configured to support the screen in a position adjustable in a height direction relative the inner module of the system. The cover may therefore provide a way to conceal the inner module of the HVAC system, such that its unpleasing appearance is hid from the eye of the beholder. Further, the cover may function as protection and prevent damages to the inner module due to things bumping into it. Even further, the cover may have soundproofing properties such that the noise generated from the inner module may be less disturbing.

[0009] According to an exemplifying embodiment of the present disclosure, the screen comprises a front surface, and a first and a second side surface, wherein the first side surface and the second side surface are arranged opposite to each other, and connected via the front surface extending between the first side surface and the second side surface, to enclose a front surface and two side surfaces of the inner module of the HVAC system. The screen may enclose one or more surfaces of the inner module.

[0010] In one example, the inner module may be installed on a floor adjacent to a wall and have a substantially rectangular shape. The screen may then enclose the inner module by having a wall extending in a vertical direction, i.e., the 'height' direction of the inner module, covering the surface of the inner module opposite to the surface facing the wall, i.e., the 'front surface'. The screen may further enclose the inner module by having two walls extending in a vertical direction covering a side surface on each respective side of the front surface. The bottom surface of the inner module, facing the floor, and the top surface of the inner module opposite to the bottom side, may be free from coverage. This is advantageous in that since most HVAC systems operate by exchanging air between the indoor environment and the outdoor environment, and therefore a fully covered inner module may prevent air from being properly distributed from or drawn into the inner module. It may further be advantageous to enclose the surfaces of the inner module having the largest area of the surfaces, and in that way enclosing an area as large as possible of the inner module without impairing the air distribution and / or extraction. Covering a larger area of the inner module means concealing a larger area of the inner module, which may be desirable. Further, the inlet and / or outlet for air from the inner module may be located on a top side, for example, why it may be desired to avoid covering or enclosing that side. In another example, the top surface and the front surface of the inner module may be covered by the screen, but not the side surfaces, for example.

[0011] In a further example, the inner module may be installed hanging from the ceiling, and the screen may then enclose a bottom surface, i.e., the surface opposite to the surface facing the ceiling, and some or each of the four side surfaces.

[0012] According to an exemplifying embodiment of the present disclosure, the screen comprises a sheet of material, and wherein the front surface, and the two side surfaces are formed by bending. The screen may therefore be formed by one part and bent into the desired shape. For example, the screen may have a u-shaped profile to cover the front surface and the side surfaces. The screen may comprise one sheet of material, or a two or more sheets of layered materials. For example, the outer surface of the screen facing the indoor environment may be comprised by a first sheet of material, and the inner surface of the screen facing the inner module may be comprised by a second sheet of material. The first sheet and the second sheet may be made from the same material, or from different materials. The first and second layer may be attached to each other with an adhesive, a laminate, sewn, or pressed, for example. The screen may for example be made from a wooden material, such as plywood, felt, textile, glass, metal, a cellulose based material or a plastic, such as acrylic glass, for example. Moreover, the screen may be made from a composite material, such as a carbon fiber. In other examples, the screen may have a first sheet comprising a stoneware, such as marble or granite. In the example where more than one sheets of material is used, the first sheet of material may be a wooden material, and the second sheet of material may be felt, or vice versa. For example, felt may be advantageous since it has soundproofing properties. Moreover, a wooden material may be more aesthetically pleasing. In one example, the screen is replaceable, and a user may choose from a range of different screens. Therefore, the cover may be adapted according to the preferences of the end user, so that they may adapt it to fit in with the interior design in the space where the inner module is intended to be installed. The cover may thus advantageously provide an aesthetically pleasing cover for an inner module of a HVAC system, for example a heat pump.

[0013] A further advantage with the screen being formed by bending is that the screen may be packaged and transported in a flat package. In one exemplifying embodiment of the present disclosure, the screen may be bendable. A bending portion may be prepared on the screen during manufacturing, enabling the screen to be bent. The bending portion may for example be a treatment of the screen, for example cutting the material and forming a bending or folding seam, to allow it to be bent or folded. The screen may then be transported to the customer or user in a flat state, whereafter the consumer or user bends or folds the screen into the desired and / or final shape. This is advantageous in that the cover may be transported in a space-efficient way, which is beneficial for the environment, and the carrier.

[0014] To arrange the screen in a position where it at least partially encloses the inner module, there is a frame arranged on an inner surface of the screen, i.e., the surface of the screen facing the inner module. The frame may provide structural support to the screen, as well as it may provide means for mounting the screen in an intended position, at least partially enclosing the inner module. According to an exemplifying embodiment of the present disclosure, the frame comprises at least one tube intended to extend along the side of the screen facing the inner module of the heat pump, and wherein the at least one tube is bent to form a shape corresponding to a desired shape of the inner surface of the screen. The frame may be a metal wire or a metal tube, for example. In some examples, the frame may be made from a hollow tube, allowing cables or other types of conduits to be drawn through the frame. The frame may follow the shape of the screen. Therefore, if the screen has a u-shaped profile, the frame may have a corresponding u-shaped profile.

[0015] According to an exemplifying embodiment of the present disclosure, the frame comprises two separate parts, a first part arranged on an upper portion of the screen and supported by the at least one hanger, and a second part arranged on a lower portion of the screen. The first part and the second part of the frame may both be formed by a tube or a wire. In one example, the first part and the second part are identical. The first part may be arranged on an upper portion of the screen, in a height direction thereof. Correspondingly, the second part may be arranged on a lower portion of the screen, in a height direction thereof. The first part and the second part may be advantageously distributed along the height of the screen to provide structural support to the screen.

[0016] According to an exemplifying embodiment of the present disclosure, the cover further comprises at least one gripping means arranged on the inner surface of the screen and configured to removably attach the frame to the screen. The frame may be attached to the screen in a removable manner, such that the screen may be exchanged without the need to exchange the frame or other components. This is advantageous since it facilitates the use of the cover and enables an end user to exchange the screen according to their needs or preferences.

[0017] According to an exemplifying embodiment of the present disclosure, the at least one gripping means is a clip. The clip may be attached to the inner surface of the screen with an adhesive, or a fastener such as nails, screws, nuts or bolts. Further, the clip may be configured to receive the frame and hold it in place by clamping around the frame. In the example where the frame is a type of tubular element, the clip may have a diameter corresponding to that of the tubular element, but with an opening having a slightly smaller diameter, such that, when received, the frame is prevented from detach from the clip. The clip may be made from a partially flexible material, such that the frame may be pushed into the opening of the clip. The partially flexible material may for example be a type of plastic.

[0018] The screen is supported by the at least one hanger in a position adjustable in a height direction relative the inner module of the system. The screen may therefore be mounted on the at least one hanger. The at least one hanger is mounted on an outer surface of the inner module of the system or on a wall adjacent the inner module. The outer surface of the inner module may be any one of the beforementioned surfaces of the inner module, for example the front surface, side surfaces, top surface or bottom surface. The wall adjacent the inner module may be the exterior wall against which the inner module may be installed. According to an exemplifying embodiment of the present disclosure, the at least one hanger is attached to the inner module or the wall adjacent the inner module with an adhesive. The at least one hanger may further be attached to the inner module or the wall adjacent the inner module with screws, or with both an adhesive and screws. The at least one hanger may therefore be fixed on the inner module or on the wall adjacent the inner module. The screen may be adjustable in a height direction by adjusting the height of the screen relative the fixed position of the at least one hanger.

[0019] According to an exemplifying embodiment of the present disclosure, the at least one hanger comprises a first part and a second part, wherein the first part is slidably arranged in a substantially vertical direction in the second part, and wherein the second part comprises a locking means configured to lock the first part in an intended position inserted in the second part. The second part of the at least one hanger may be attached to the inner module or the wall adjacent the inner module. The first part may not be fixed nor attached to the inner module or the wall. Instead, the first part is coupled to the second part by being slidably arranged in the second part in a vertical direction, such that the first part may move in a height direction relative the second, attached, part. The substantially vertical direction may correspond to the height direction of the inner module and the screen. Moreover, the locking means may secure the first part in the intended position relative the second part. This is advantageous in that it allows the first part to be adjustable in a height direction relative the second part of the hanger, which may be in a fixed position. Since the at least one hanger supports the frame and the screen, this means that the screen may be adjustable in a height direction relative the inner module. This is particularly advantageous since it enables the screen to be adjustable in relation to the inner module, meaning that the screen may be adapted to the installation position of the inner module. An end user installing the cover may therefore not be limited by the installation position of the inner module but may instead adapt the cover to correspond to that position. The height of the inner module may alter depending on the provider, the preferences of the user or the conditions in the building where it is installed. Therefore, it is important that the cover may be adapted to work for more than one type of inner module, and more than one height.

[0020] According to an exemplifying embodiment of the present disclosure, the locking means comprises a plurality of teeth configured to engage with corresponding teeth arranged on the first part, in a male / female configuration. The second part may comprise a groove in which the first part may be slidable arranged in. The groove may comprise a plurality of teeth for locking the first part in the intended position. The teeth may function as barbs and have a shape corresponding to that of an end portion of the first part. Therefore, when the first part is slidably inserted into the groove of the second part, the first part may easily slide in one direction, but when trying to withdraw the first part from the groove, the teeth prevent the first part from being extracted, therefore functioning as barbs. The plurality of teeth may be distributed along a length of the second part and correspond to different levels of height. The adjustable height may range between 0 and 20 centimeters, for example.

[0021] According to an exemplifying embodiment of the present disclosure, the at least one hanger comprises a u-shaped support configured to receive the frame. The frame may therefore be hung on the u-shaped support on the at least one hanger. This is advantageous in that the screen may easily be mounted on the at least one hanger, which facilitates the installation for the user. Further, the screen may easily be lifted off the at least one hanger and thereby uncover the inner module, facilitating the replacement of the cover or removal of it. According to an exemplifying embodiment of the present disclosure, the u-shaped support is arranged on the first part of the at least one hanger. The frame may therefore be hung on the part of the at least one hanger that may be adjusted in a height direction, allowing the screen to be adjusted in a height direction.

[0022] According to an exemplifying embodiment of the present disclosure, the at least one hanger is two hangers arranged at different positions on the inner module or the wall adjacent the inner module. The two hangers may for example be positioned on each of the side surfaces of the inner module, or on two respective sides in a horizontal direction of the inner module. Having more than one hanger is advantageous since it distributes the weight of the screen on the two hangers and increases the stability of the arrangement. It further enables the screen to be hanged in a balanced position, not being skewed in a horizontal direction relative the inner module or the wall.

[0023] According to an exemplifying embodiment of the present disclosure, the cover further comprising an adjustable wall support arranged at an end portion of the frame, and configured to support the screen in a position adjustable in a depth direction relative the inner module of the heat pump and to rest against a wall adjacent the inner module of the heat pump. The frame may have an end portion arranged adjacent the wall, in an installed position. In the example where the frame is a tubular element, the end portion may be an end portion of the tubular element. The wall support may be an additional component mounted on the end portion of the frame. In one example, the wall support is a type of stopper with an adjustable length. The stopper may be threaded onto the end portion of the frame. The stopper may therefore comprise a recess or a hole such that it may be sleeved around the end portion of the frame. The wall support may be available in different lengths, such that the screen may be installed with a distance to the inner module and / or with a distance to the wall adjacent the inner module. The wall support lets some of the weight of the screen to rest against the wall. Further, the wall support and the at least one hanger both carry the screen and the frame to install them into a desired position. The wall support supports the screen in a horizontal direction, while the at least one hanger supports the screen in a vertical direction.

[0024] It may be important to maintain a distance between the cover and the inner module, and / or the wall adjacent the inner module, to allow air to circulate around the inner module. Another reason to maintain a distance between the cover and the inner module may be to allow for cable routing. Some HVAC systems require a number of cables to be drawn to and / or from the inner module. In some cases, the cables may consume a significant amount of space around the inner module. Thus, it may be desired to conceal the cables as well as the inner module, and therefore the cover may be arranged at a distance from the inner module, such that the cables fit within the cover. The wall support may comprise one or more stoppers, forming the wall support. The one or more stoppers may be connected to each other, for example by being threaded onto each other, and onto the end portion of the frame, such that a user may remove or attach a stopper to the wall support, to thereby adjust the distance between the screen and the wall. The one or more stoppers may also come in individual sizes or lengths, such that a user may choose the stopper suitable for their installation. In this example, the stoppers may be attached to the end portion of the frame individually. In a further example, the one or more stoppers may be one stopper threaded onto the end portion, and wherein the whole length of the stopper is threaded, such that the distance may be adjusted by threading the stopper a desired length onto the end portion. The one or more stoppers may also be arranged in a telescopic arrangement, either by itself or connected to each other, to enable adjustment of the length.

[0025] The present embodiment is advantageous in that it increases the modularity of the cover and allows the user to adapt the cover to the conditions of their HVAC system installation. The wall support is further advantageous in that it prevents the frame from leaving a mark on the wall, which may be difficult to get rid of. The wall support may thereby function as a cushion or a padding for the frame, which further has the advantage of preventing the frame from sliding against the wall. The wall support may for example be made from a material such as rubber, a thermoplastic, felt, or a wooden material or a combination of materials.Brief description of the drawings

[0026] Exemplifying embodiments will now be described in more detail, with reference to the following appended drawings, in which: Figure 1 illustrates a perspective view of a cover according to an exemplifying embodiment of the present disclosure; Figure 2 illustrates a perspective view of a cover installed around an inner module of a HVAC system according to an exemplifying embodiment of the present disclosure; Figure 3 illustrates a front view of a cover according to an exemplifying embodiment of the present disclosure; Figure 4 illustrates a top view of the cover according to an exemplifying embodiment of the present disclosure; Figures 5a-d illustrates different views of a hanger according to an exemplifying embodiment of the present disclosure; Figure 6 illustrates a perspective view of a gripping means according to an exemplifying embodiment of the present disclosure. Detailed description

[0027] As illustrated in the figures, the size of the elements and regions may be exaggerated for illustrative purposes and, thus, are provided to illustrate the general structures of the embodiments. Like reference numerals refer to like elements throughout.

[0028] Exemplifying embodiments will now be described more fully hereinafter with reference to the accompanying figures, in which currently preferred embodiments are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the invention to the skilled person.

[0029] With reference to figure 1, a perspective view of a cover 100 according to an exemplifying embodiment of the present disclosure is shown. The cover 100 has a width w, a height h and a depth d. The width w is greater than the height h. The cover 100 comprises a screen 110 and a frame 120. The screen 110 is formed from a bent sheet of material, and the bent portions 115 are seen forming two corners 115 on the screen 110. The screen 110 forms a u-shape with three sides, a longer side a and two shorter, opposite sides b, c. The bent portion 115 may be bent with an angle α. The angle α may range between 80 to 150 degrees, for example.

[0030] The screen 110 has an inner surface 111 on which the frame 120 is attached. The frame 120 comprises two parts, a first part 120a, and a second part 120b. The first part 120a is arranged on an upper portion 110a of the screen 110, and the second part 120b is arranged on a lower portion 110b of the screen 110. The first part 120a and the second part 120b are thus separated from each other with a distance along the height direction h of the cover 100. The frame 120 is comprised by a wire or a tube with a substantially circular cross-section. The frame 120 is attached to the screen 110 with clips 170. There are a number of clips 170 distributed horizontally along the screen 110, on all sides a, b, c. The clips 170 clamps the frame 120 such that the frame is attached to the screen 110. The clips 170 may be attached to the screen with an adhesive or via fasteners, for example. The second part 120b of the frame 120 comprises a wall support 160 attached to an end portion 122 thereof. The wall support 160 is intended to rest against a wall (not visible) adjacent to the inner module (not visible) around which the cover 100 is installed. The wall support forms a partial sleeve around the end portion 122 of the second part 120b of the frame. The first part 120a of the frame 120 rests on a pair of hangers 130a, 130b. The hangers 130a, 130b are attached to the inner module (not shown). The hangers 130a, 130b are arranged towards the shorter opposite sides b and c of the screen 110. The hangers 130a, 130b each comprise a u-shaped support 131 configured to receive the first part 120a of the frame 120. The u-shaped support 131 prevents the first part 120a of the frame 120 from falling off or being detached from the hangers 130a, 130b. The screen 110 has three larger faces, or 'surfaces', facing the indoor environment where the cover 100 is installed. There is a front surface (not visible) opposite to the inner surface 111, a first side surface 113, and a second side surface (not visible).

[0031] The cover 100 is seen installed around an inner module 200 of a HVAC system in figure 2. In other words, figure 2 illustrates the cover 100 installed in an indoor environment, partially enclosing an inner module 200. The inner module 200 may be attached to the wall 300, as illustrated in the figure. In other examples, the inner module 200 may stand on a floor (not visible) against or adjacent the wall 300. The HVAC system may also include floor and / or wall mounted radiators. In the example shown in figure 2, the inner module 200 may be part of an air conditioning system. The screen 110 is illustrated with dotted lines. The front surface 112 of the screen 110 is facing the indoor environment surrounding the inner module 200. The inner surface (not visible) of the screen 110 is facing the inner module 200. The screen 110 further comprises a first side surface 113 and a second side surface 114 facing the indoor environment. The longer side a and the two shorter, opposite, sides b, c together encloses parts of the inner module 200. The shape of the screen 110 corresponds to the shape of the inner module 200, for example, the bent portions 115 of the screen coincides with the corners 215 of the inner module 200.

[0032] The holder 130 visible in figure 2 is attached to an outer surface 210 of the inner module 200. In the example shown in the figure the holder 130 is attached to one of the shorter side surfaces (which forms part of the outer surface 210) of the inner module 200. The holder 130 may be attached to the inner module 200 with a type of adhesive, for example. Thereby, no modification to the inner module 200 is required to install the cover 100 around the inner module 200. The first part 120a of the frame 120 is supported by the u-shaped support 131 on the hanger 130. The cover 100 is thereby supported in a vertical direction by the holder 130 together with the inner module 200. The installation position of the screen 110 can be adjusted with the holder 130. By raising or lowering the screen 110 relative a height direction of the inner module 200, the position of the screen 110 may be adjusted to coincide with the position of the inner module 200.

[0033] The second part of the frame 120b has an end portion 122, where a wall support 160 is attached. The wall support 160 rests against the wall 300, and thereby supports the cover 100 in a horizontal direction. The wall support 160 is adjustable in a depth direction relative the depth of the inner module 200. The position of the screen 110 may therefore be adjusted and adapted to a depth of the inner module 200 around which it is installed.

[0034] Moreover, the cover 100 may be mounted entirely on the inner module 200, why no modification to the wall which it rests against is required. This is advantageous in that it facilitates the installation of the cover 100, where no tools are required, while avoiding making any interventions on the wall, such as bore holes.

[0035] With reference to figure 3, a front view of a cover 100 according to an exemplifying embodiment of the present disclosure is shown. The outer surface of the screen 110 comprised by the front surface 112, the first side surface 113 and the second side surface 114, as well as the bent portions 115, has a smooth, flat finish. The screen 110 is made from a sheet of material that is bent to achieve the finishing shape. The sheet of material may for example be a wooden material, a felt material, a metal, a textile, a stoneware, a composite, a ceramic material, a plastic, etc. Moreover, the screen 110 may be made from one or more layers of a sheet of material. For example, the inner surface (not visible) may be comprised by one sheet of material, and the outer surface may be formed from a second sheet of material. In another example, the user may choose the finish of the screen 110. The user may for example choose to paint the outer surface of the screen 110 or choose a type of wood matching with other furniture in the indoor environment where the cover 100 is installed. The front surface 112 of the screen 110 has a top end 112a and a bottom end 112b. The top end 112a, in an installed position, is arranged to coincide with a top end of the inner module 200, and the bottom end 112b is arranged to coincide with a bottom end of the inner module 200.

[0036] With reference to figure 4, a top view of the cover 100 according to an exemplifying embodiment of the present disclosure is shown. The inner module 200 is not visible in the present figure. Instead, there is shown a space 200a formed between the wall 300 and the cover 100 when the cover 100 is installed. The inner module 200 fits in the space 200a. The figure illustrates the cover 100 from a top view, meaning that it is shown from the top end 112a of the front surface of the screen 110. The wall support 160 comprises three parts, a first part 160a, a second part 160b and a third part 160c. The first, second and third parts 160a, 160b, 160c are attached to each other to form the wall support 160. However, the first, second and third part 160a, 160b, 160c of the wall support 160 are detachable from each other, such that the distance along a horizontal direction between the wall 300 and the front surface 112 of the screen 110 may be adjusted. The third part 160c of the wall support 160 may for example, be detached from the second part 160b of the wall support 160, leaving the first part 160a and the second part 160b forming the wall support 160. In another example, the third part 160c and the second part 160b of the wall support 160 are detached from the first part 160a. In yet another example, only the second part 160b of the wall support 160 is detached. In this way, a user may adjust the distance between the wall 300 and the front surface 112 of the screen 110 according to their own preferences. In a further example, the first part 160a, the second part 160b, and the third part 160c may be individual and separate parts with different lengths. The user may receive all parts, and thereafter choose which one of the first part 160a, the second part 160b and the third part 160c that suits their installation best. In yet a further example, the wall support 160 may be formed by one single piece, threaded onto the end portion 122. The distance may, in this case, be adjusted by threading the wall support 160 a desired length onto the end portion 122. Alternatively, wall support 160 is attached to the end portion 122 and adjusted by the means of a telescopic arrangement.

[0037] With reference to figure 5a, a perspective view of a hanger 130 according to an exemplifying embodiment of the present disclosure is shown. The hanger 130 comprises a first part 140 and a second part 150. The first part 140 is slidably arranged in the second part 150 via a groove (not visible) in the second part 150. The first part 140 comprises a grip 141 for a user to grip a hold of to adjust the height of the screen 110 relative the inner module 200. The grip 141 may have a shape that fits a fingertip, such that a user may easily grip and hold the grip 141 while adjusting the height. The first part 140 of the holder 130 further comprises a u-shaped support 131 to receive and support the frame 120. The u-shaped support 131 has a shape corresponding to a shape of the frame 120. For example, if the frame 120 is a tube with a circular cross-section, the u-shaped support 131 may have a rounded u-shape for receiving the frame 120.

[0038] With reference to figures 5b and 5c, the hanger 130 is shown in having its maximum adjustment height. The first part 140 is slid out from the groove 153 of the second part 150 as much as possible, in a direction illustrated by an arrow in the figure. The grip 141 functions as a stopper, preventing the first part 140 from detaching completely from the second part 150. The second part 150 comprises a front portion 154, also preventing the first part 140 from falling out from the groove 153. In figure 5c, the second part 150 is shown without the front portion 154. The second part 150 comprises a locking means 151, for locking the first part 140 in an intended position in the second part 150. The locking means 151 comprises a plurality of teeth 152, arranged along the sides of the second part 150. The teeth 152 secures the first part 140 in a desired position within the groove 153. The first part 140 comprises a mating portion, or a corresponding tooth 142, fitting into the teeth 152 in a male / female configuration. When the tooth 142 is engaged with a set of teeth 152, the first part 140 is thereby prevented from being slid out from that position in the direction of the arrow, or in the opposite direction. To disengage, and 'unlock' the first part 140, for example if the height needs adjusting, the user may push the two grips 141 towards each other, to detach the tooth 142 of the first part 140 from the set of teeth 152 of the second part 150. While pushing the two grips 141 towards each other, the first part 140 may be slid up and down in the groove 153, until a desired height is reached. Thereafter, the two grips 142 may be released and the first part 140 locked in the groove 153 in the desired position.

[0039] Figure 5d shows the rear part 155 of the holder 130, being attached to the inner module (not visible). The rear part 155 has a smooth, flat surface, to correspond to a smooth, flat surface of the inner module where it should be attached.

[0040] With reference to figure 6, a perspective view of a gripping means 170 according to an exemplifying embodiment of the present disclosure is shown. The gripping means 170 is a clip, comprising two clamps 171 arranged thereon, and configured to receive the frame 120. Through-holes 175 are arranged around the clamps 171, releasing the pressure on the clip 170 when the frame 120 is inserted. When the frame 120 is inserted into the clamps 171, the clamps 171 will be momentarily deformed by the force from the frame 120 being pushed into the clamps 171. This force may propagate into the remaining area of the clip 170, in the long-term causing fatigue. The through-holes 175 prevent this from happening since they are able to absorb the force and reduces the deformation from the clamps 171.

[0041] Further, the clip 170 may be attached to the inner surface (not visible) of the screen (not visible) via screws 173 screwed through bore holes 172 in the clip 170. The clip 170 may further be attached to the inner surface with an adhesive, or with a combination of an adhesive and screws 173.

[0042] Although features and elements are described above in particular combinations, each feature or element can be used alone without the other features and elements or in various combinations with or without other features or elements.

[0043] Additionally, variations to the disclosed embodiments can be understood and effected by the skilled person in practicing the claimed invention, from a study of the figures, the disclosure, and the appended claims. In the claims, the word "comprising" does not exclude other elements, and the indefinite article "a" or "an" does not exclude a plurality. The mere fact that certain features are recited in mutually different dependent claims does not indicate that a combination of these features cannot be used to advantage.
