Description

Technical field

The invention relates to the field of air processing units, and more particularly, to the field of air processing units intended for installation in suspended ceilings.

State of the art

Air handling units (BOW), i.e. airflow processing devices capable of also creating or generating said airflow are now widely known. Processing said air stream includes the use of air filters to remove unwanted particulate matter from the air. In addition, the air treatment may also include or not include heating or cooling said air, humidifying or drying it, etc.

Due to the removal of the aforementioned solid particles, such as dust, pollen and bacteria, these air filters must be replaced or at least cleaned during operation so often as to prevent them from clogging with these particles, as a result of which the filters may not only cease to fulfill their function , but also lead to improper operation of the air treatment units, which, in turn, can lead to their failure.

Installing air handling units in areas hidden from view is also known. It is common practice to install these units in suspended ceilings. Such an arrangement of the aforementioned blocks does not have any undesirable effect on the appearance of the rooms in which they are installed.

However, with this arrangement of the air handling units, access to the air filters is limited. This limited access is a consequence of the location in each specific case, since in order to gain access to the air filters, it is necessary in some cases to pass through the side or vertical wall of the block, and in other cases, through the lower or horizontal wall of the block. In this regard, the design of the air handling units is specific to each or both of these cases. In other words, the design of the air treatment units is developed specifically in each case, so as to provide lateral access or bottom access to the aforementioned air filters.

Given the shortcomings or limitations of today's solutions, there is a need to develop a solution that would provide access to the air filters of the air treatment units regardless of the location of these air filters.

Disclosure of invention

To accomplish this task and solve the above technical problems, as well as to provide additional benefits discussed below, the invention is directed to the creation of an air treatment unit (BOW), which provides flexibility in installing and removing air filters, since it provides access to the air filter, possible through parts located at an angle to each other, for example, through the side walls and through the bottom wall.

The air processing unit comprises a space for accommodating an air filter therein and a support comprising a structure for holding the air filter, including a guide along which the air filter is able to move between the inner part and the outer part of the structure in the first direction; and space guiding means for moving the structure between the inner part and the outer part of the air processing unit in a second direction.

The air processing unit further comprises a first opening for passing the air filter between the inner part and the outer part of the air processing unit in a first direction; and a second hole for passing the structure between the inner part and the outer part of the air processing unit in the second direction. The first direction and the second direction extend at an angle to each other, and the magnitude of this angle is from 75 ° to 105 °, preferably 90 °.

The support further comprises first fixing means configured to fix the air filter in the structure by applying pressure. The first fixing means are for fixing the air filter in the structure. These first locking means comprise a guiding element and a groove whose direction does not coincide with the first direction, said guiding element and groove being made so that when the guiding element is in the groove between them, relative movement is possible. For this, preferably, the support further comprises a first profile in which a groove is made, and a guide element is attached to the structure.

Preferably, there are two first profiles, said first profiles being held relative to two sides of the structure parallel to each other. If necessary, at least one of the first profiles has a tapering element attached to it, designed to narrow the guide along which the air filter can be moved. Thus, the guide can be used for air filters of different sizes.

The support further comprises second locking means configured to fix the structure in space by applying pressure. The second locking means are designed to fix the structure in space. These second fixing means comprise a guide part and a channel whose direction does not coincide with the second direction, said guide part and channel being made so that if the guide part is in the channel, relative movement is possible between them. For this, preferably, the support further comprises a second profile in which the channel is made, and the guide part is fixed in the bulk space.

Preferably, there are two second profiles, said second profiles being held relative to the fixed parts of the air treatment unit.

Embodiments of the invention

The invention relates to an air processing unit (BOW), i.e. a unit for processing at least one air stream. An air processing unit (BOW) may also be configured to create or generate said air flow. Processing said air stream includes air filtration to remove unwanted particulate matter from the air. In addition, the air treatment may also include or not include heating or cooling said air, humidifying or drying it, etc.

The air processing unit comprises an external housing for enclosing the compartment. The specified housing is limited to the sides, preferably six sides, and contains panels surrounding various components, such as, for example, at least one air filter (1). In this sense, the air processing unit comprises at least one space (2) limited in the compartment. Each of the spaces (2) is designed to accommodate one of the air filters (1).

The air processing unit comprises a window (3) made in one of the side walls of the outer casing, in particular in accordance with the space (2), for communicating by fluid between the inner part and the outer part of the air processing unit. Thus, the air processing unit may comprise an air-driving element (4), which allows air to circulate through the air processing unit.

The air processing unit comprises a first opening (5) for providing communication between the inner part and the outer part of the air processing unit. The first hole (5) is located in accordance with the space (2) so that the air filter (1) can be inserted into the space (2) and removed from the space (2) through the specified hole. In addition, preferably, the first hole (5) is located on the other one of the sides of the outer casing, different from the side on which the window (3) is located. The air processing unit comprises a first cover (5 ') for covering or closing the first hole (5).

In addition, the air treatment unit includes a second hole (6) to provide communication between the inner part and the outer part of the air treatment unit. The second hole (6) is also located in accordance with the space (2) so that the air filter (1) can be inserted into the space (2) and removed from the space (2) through the specified hole. In addition, preferably, the second hole (6) is located on the other additional side of the outer casing, different from the sides on which the window (3) and the first hole (5) are located. More specifically, this other additional side of the outer casing is angled with respect to the side on which the first hole (5) is located, preferably at an angle of 90 ° to said side.

The air processing unit comprises a second cover (6 ') for covering or closing the second hole (6). Preferably, the air processing unit further comprises levers (6.1) pivoting at their longitudinal ends to move the second cover (6 ') between the open position and the closed position in which said cover is held attached to the outer casing. In this way, the likelihood of a fall or unintentional detachment of the second cover (6 ') is prevented.

The air processing unit further comprises a support (7) for installing an air filter (1). The support (7), in turn, contains a structure (8) for holding the air filter (1), having sides, preferably six sides, forming a guide along which the air filter (1) can move. In addition, the structure (8) contains a removable corner element (8.1) to simplify the assembly operation of the block. Thus, the space (2) is additionally made with the possibility of placing in it the specified structure (8).

The air filter (1) can move along the guide relative to the structure (8) in the first direction (A). The guide has an open end (8 ') corresponding to one of the sides of the structure (8) to enable the air filter (1) to move between the inner part and the outer part of the structure (8); in other words, one of the sides of the structure (8) is designed so that the air filter (1) can pass through it.

In the place where the structure (8) is located in the space (2), the open end (8 ') of the rail faces or corresponds to the first hole (5) so that the air filter (1) can be inserted or removed from the space (2) , and therefore from the air processing unit, by moving the structure (8) along the guide in the first direction (A) through the first hole (5).

Thus, the air processing unit provides the air filter (1) with a first path through one side of the outer casing.

The structure (8), in turn, can move relative to the space (2) in the second direction (B). The support (7) comprises guiding means (9) arranged in accordance with the space (2) for guiding the structure (8), the air filter (1) being placed in the structure as it moves in the indicated direction (B) between the inner part and the outside of the air handling unit. The first direction (A) and the second direction (B) extend at an angle to each other, and the magnitude of this angle is from 75 ° to 105 °, preferably 90 °.

The guide means (9) are fixed elements fixed to the inside of the air processing unit, preferably on racks.

Preferably, the fixed elements are attached to one side of the outer casing at the first longitudinal end and to the other side of the outer casing at the second longitudinal end, and these sides are preferably parallel to each other.

In this regard, in addition to the fact that the size of the second hole (6) is selected so that it is possible to insert and remove the air filter (1), the size of the second hole (6) is also chosen so that the structure (8) can also be insert and remove through this hole.

Thus, the air processing unit provides the air filter (1) a second path through the other side of the outer casing, different from the one through which the first access is provided.

Thus, the air processing unit provides access to the air filter (1) when the air filter (1) is located in space (2), either through the first hole (5) or through the second hole (6), and these holes (5, 6) are located in planes located at an angle to each other, and the value of this angle is from 75 ° to 105 °, preferably 90 °. Thus, the air processing unit according to the invention provides access to the air filter (1) through one of the openings or through both of these openings (5, 6), depending on the installation of the unit in a suspended ceiling.

In the embodiment shown in the drawings, in accordance with the operating position of the air treatment unit, the first hole (5) can be located in a vertical plane, and the second hole (6) can be located in a horizontal plane, on one of the sides and on the bottom side of the outer casing, respectively.

In another embodiment, when the air processing unit is in the operating position, moving the air filter (1) along the guide in the first direction (A) leads to the introduction of the air filter into space (2) or removal from it in a horizontal plane, and the movement of the structure (8) with respect to the space (2) in the second direction (B), the structure (8) is introduced into or removed from the air processing unit in a vertical plane through the sides and the lower side, respectively.

The support (7) contains the first fixing means for fixing the air filter (1) in the structure (8) by applying pressure. These first fixing means provide for both fixing the air filter (1) and separating it from the structure (8) in a quick and easy way. The specified fixation is provided by pressing, and the specified separation is carried out by pulling.

The first locking means include at least one guide element (10) and a groove (11). Preferably, the structure is provided with at least two guide elements (10) and two grooves (11), so as to ensure stability when moving the guide elements (10) and grooves (11) relative to each other.

The guide elements (10) contain a head whose size is larger than the size of the grooves (11), as well as an elongated body, the dimensions of which are smaller than the dimensions of these grooves (11). Thus, the guide elements (10) can be fixed by inserting the bodies into the corresponding grooves (11), and the axial direction of movement is limited by the longitudinal length of the body due to the contact of the heads with the grooves (11), but at the same time, the possibility of movement guide elements (10) along the grooves (11).

The grooves (11), in turn, have a start point and an end point connected by an extended part defined by a bend. In addition, the start and end points are located so that the imaginary connecting line (not shown in the drawings) is offset or angled to the first direction (A). Thus, by means of the guide elements (10) and the grooves (11), a combined movement is provided, consisting in longitudinal movement in the first direction (A) and lateral movement in the direction perpendicular to the first direction.

The support (7) further comprises at least a first profile (12), which makes it possible to adapt the invention to conventional air filters (1), i.e., without the need to add guide elements (10) or grooves (11) to conventional air filters ( one).

In the embodiment shown in the drawings, the grooves (11) are made in the first profile (12), and the guide elements (10) are fixed in the structure (8) using their heads, ensuring that the first profile (12) is held in the axial direction. To fix the guide elements (10) in the structure (8), the first locking means may further comprise connecting elements (10 ') attached to the free ends of the elongated bodies. Alternatively, the grooves (11) can be located in the structure (8), and the guide elements (10) can be attached to the first profile (12).

The first profile (12), passing in the longitudinal direction, is made in such a way that its movement in the longitudinal direction is limited by the heads of the corresponding guide elements (10) relative to one side of the structure (8), the upper side, and at the same time it can move in parallel the indicated side of the structure (8). By pushing and pulling the first profile (12), it can be moved in the direction of the length of the grooves (11). Thus, the first profile (12) can move longitudinally in the first direction (A) and transversely, moving closer and further from one side of the structure (8), namely, the larger side, perpendicular to the side to which the corresponding guide elements are attached (10 )

Thus, if the first profile (12) moves in one direction, it also moves in the transverse direction to the indicated larger side of the structure (8), so that when the air filter (1) is inside the structure (8), it is pressed against the larger side of the structure (8).

In the embodiment shown in FIG. 2A and 2B, the support (7) comprises a tapering member (12 ') attached to the first profile (12) so that they move together. In this embodiment, the tapering element (12 ') presses the air filter (1) against the indicated larger side of the structure (8). The tapering element (12 ') is used to enable the use of the structure (8) in case the air filter (1) has smaller dimensions or at least a smaller width than the guide. In yet another embodiment shown in FIG. 3, the support (7) does not contain a tapering element (12 '), so that the first profile (12) directly presses the air filter (1) to the larger side of the structure (8). This embodiment allows the use of the structure (8) when the air filter (1) has smaller dimensions or at least a smaller width than the guide.

Similarly, when the first profile (12) moves in a different direction opposite to the previous one, said first profile (12) also moves in the transverse direction, moving away from the larger side, so that if the air filter (1) is inside the structure (8) , the air filter (1) is no longer affected by the pressure holding it on the guide, which is transmitted directly either through the first profile (12) or through the tapering element (12 ').

Preferably, there are two first profiles (12) to provide more significant pressure on the larger surface of the air filter (1), i.e. to create a more effective and uniform pressure. In this sense, the first profiles (12) are made in such a way that they are attached to two sides of the structure (8), namely, the upper and lower sides, located opposite each other, i.e. facing each other. Similarly, said first profiles (12) can both move in the same transverse direction to press the air filter (1) against the same surface of the structure (8), i.e. to a larger surface, and in the other direction, to stop pressing the air filter (1) to a larger surface. Similarly, it is preferable to use two tapering elements (12 '), one for each of the first profiles (12).

The support (7) contains second locking means for fixing the structure (8) in space (2) by applying pressure. These second fixing means provide for both fixing the structure (8) in the space (2) and removing it from the space (2) in a quick and easy way. The specified fixation is provided by pressing, and the specified separation is carried out by pulling.

Second locking means include at least one guide portion (13) and a channel (14). Preferably, the structure is provided with at least two guide parts (13) and two channels (14) to ensure stability when moving the guide parts (13) and channels (14) relative to each other.

Preferably, the guide parts (13) are similar in design to the guide elements (10) and the channels (14) are similar to the grooves (11). In this regard, the guide parts (13) have a protrusion, the size of which is larger than the size of the channel (14), and at the same time, the elongated part, the size of which is smaller than the size of the specified channel (14). Thus, the guide parts (13) can be fixed by inserting the elongated parts into the corresponding channels (14), and the restriction of movement in the other axial direction is provided in accordance with the longitudinal length of the body due to the contact of the protrusions with the channels (14), but at the same time at the same time, it is possible to move the guide parts (13) along the channels (14).

Channels (14), in turn, have a start point and an end point connected by another curve. In addition, the start and end points are located in such a way that the other imaginary connecting line (not shown in the drawings) is offset or angled to the second direction (B). Thus, by means of the guide parts (13) and channels (14), a combined movement is provided, consisting in longitudinal movement in the second direction (B) and lateral movement in the direction perpendicular to the second direction (B), and preferably also the first direction ( A).

In addition, the support (7) contains at least a second profile (15) to enable the invention to be applied to conventional air treatment units.

In the embodiment shown in the drawings, the channels (14) are made in the second profile (15), and the guide parts (13) are attached to the fixed parts of the air processing unit, using protrusions, restricting the movement of the second profiles (15) in another axial direction. These fixed parts may be guiding means (9) and / or panel panels. Alternatively, the channels (14) can be made in the fixed parts of the air processing unit, and the guide parts (13) can be attached to the second profiles (15).

The second profile (15), extended in the longitudinal direction, is made so that its movement in the longitudinal direction is limited by the protrusions of the respective guide parts (13) relative to one of these fixed parts of the air treatment unit, and at the same time, it can move parallel to the specified fixed part . By pushing and pulling the second profile (15) it can be moved in the direction of the length of the channels (14). Thus, the second profile (15) can move longitudinally in the second direction (B) and laterally, moving closer and moving away from one side of the structure (8), preferably from the same side of the larger size, as in the case of the first profiles.

Thus, if the second profile (15) moves in one direction, the specified second profile (15) also moves in the transverse direction to the larger side of the structure (8), so if the structure (8) is in space (2), the structure (8) is pressed by the second profile (15) to the fixed part of the air processing unit, for example, to at least one of the pillars of the support (7). Similarly, if the second profile (15) moves in a different direction opposite to the above, the specified second profile (15) also moves in the transverse direction, moving away from the larger side, so if the structure (8) is in space (2), the action the pressure holding the structure (8) in the space (2) ceases.

Preferably, there are two second profiles (15) to provide more significant pressure on the large surface of the structure (8), i.e. to create a more effective and uniform pressure. To this end, the second profiles (15) are designed so that they are pressed against the stationary parts of the air processing unit. Similarly, said second profiles (15) can both move in the same transverse direction to press the air filter (1) against the same surface of the structure (8), i.e. to a larger surface, and in the opposite direction, in order to stop pressing the air filter (1) against the structure (8).

For this, the second profiles (15) are formed by two flat parts located at an angle, preferably 90 ° to each other, with the channels (14) or, alternatively, the guide parts (13) located on one of the two flat parts, and the other of these two flat parts is an element of the second profiles (15), whereby it is possible to exert pressure on the structure (8).

Similarly, the first profiles (12) are formed by two flat parts located at an angle, preferably 90 ° to each other, and the grooves (11) or, alternatively, the guide elements 10 are made on one of these two flat parts, and the other of these of two flat parts is an element of the first profiles (12), whereby it is possible to create pressure on the air filter (1) either directly or using the corresponding tapering element (12 ').

As seen in FIG. 4 to 7, in order to remove the air filter (1), the first cover (5 ') is first removed to provide access to the first hole (5) so that the first profile (12) can be pulled out so that these first profiles (12) moved towards the outer part of the air processing unit by a distance corresponding to the length of the grooves (11), which is offset from the first direction (A). After such a transverse longitudinal movement of the first profiles (12), the pressure from the side of the first profiles (12) no longer acts on the air filter (1) and can be removed from the structure (8) through the open end (8 '), and therefore from the air treatment unit through the first hole (5).

To install the air filter (1) inside the air treatment unit, after removing the first cover (5 ') to provide access to the first hole (5) and move the first profiles (12) towards the outer part of the air treatment unit at a distance corresponding to the length of the grooves (11), the air filter (1) can be introduced into the space (2), more precisely, installed in the structure (8). After installing the air filter (1) in the structure (8), the first profiles (12) are moved in the longitudinal and transverse directions towards the inside of the air treatment unit to a distance corresponding to the length of the grooves (11) in order to fix the specified air filter (1) in structures (8) due to the pressure created by these first profiles (12). Then, by means of the first cover (5 '), said first opening (5) is closed.

As can be seen in FIG. 8 to 13, showing a different sequence of operations, in order to remove the air filter (1), first remove the second cover (6 ') to provide access to the second hole (6) so that the second profiles (15) can be pulled out so that these the second profiles (15) moved towards the outer part of the air processing unit by a distance corresponding to the length of the channels (14), which is offset from the second direction (B). After such a transverse-longitudinal movement of the second profiles (15), pressure on the side of the second profiles (15) no longer acts on the structure (8), and it can be removed from the compartment (2) through the second hole (6). Therefore, the air filter (1) can also be removed through one of the horizontal sides of the outer casing of the air treatment unit. After removing the structure (8) from the space (2), the first profiles (12) can be moved to release the air filter (1) and to remove it through the open end (8 ') of the guide, moving it in the first direction (A).

To install the air filter (1) in the air treatment unit, after moving the first profiles (12) so that the air filter (1) can be inserted or installed in the structure (8), the air filter (1) is inserted, and the first profiles (12 ) move in the opposite direction to ensure that it is pressed against the air filter (1) and, thus, fix the specified air filter in the structure (8) by applying pressure. After that, the second cover (6 ') is removed to provide access to the second hole (6), and the second profiles (15) are pulled out of the space (2) so that the structure (8) can be inserted or placed into the space (2), the structure (8) is inserted into the space (2), and the second profiles (15) are pushed towards the inside of the space (2) to fix the structure (8) in the specified space (2) by applying pressure.
