Description

Technical Field

[0001] The utility model generally relates to equipment associated with air treatment technology (such as air conditioning, ventilation, heating, cooling, filtering / purification and / or dehumidification, etc.), and more particularly to a fan assembly for a dehumidifier. Background Art

[0002] Fans including fan housings of various configurations are known and used in different applications, for example in stand-alone applications or in conjunction with air handling systems in buildings such as public areas, ice hockey arenas, etc. Examples of such air handling systems include dehumidifiers for dehumidification of air.

[0003] A typical fan housing includes a housing configured to receive a motor-driven fan for moving a gaseous substance (e.g., air) from an inlet of the housing via an interior of the housing to an outlet of the housing. However, typical fan configurations (e.g., a complete fan with an associated housing and / or a housing configured to receive the fan) require complex design and / or are associated with excessive energy consumption during use in order to achieve desired characteristics (e.g., desired characteristics associated with airflow control such as control of flow rate, pressure, etc.). Thus, such complexity, lack of energy efficiency, and / or unsatisfactory performance associated with typical fan configurations also impacts the overall performance and / or design complexity of an integrated system, i.e., a dehumidifier system incorporating a fan configuration for facilitating the distribution of dehumidified air.

[0004] Therefore, there is a need for improvements in fan configurations associated with dehumidifiers. Utility Model Content

[0005] The purpose of the present invention is to mitigate, alleviate or eliminate one or more of the deficiencies and disadvantages in the prior art and to solve at least one of the current problems.

[0006] In particular, prior art fan configurations including prior art configurations of a fan housing (i.e., fan configurations used in conjunction with dehumidifiers) typically require complex designs and / or are associated with excessive energy consumption during operation of the fan unit (housed within the fan housing) in order to achieve desired performance for the fan configuration (e.g., desired performance associated with airflow control such as control of flow, pressure, etc.) depending on the intended application.

[0007] These and other objects that will become apparent from the following description are achieved by a fan assembly for a dehumidifier and a dehumidifier configured to be provided with the fan assembly as set forth in the main aspects.

[0008] According to one aspect of the utility model, a fan assembly for a dehumidifier is provided. The fan assembly includes a fan unit and a fan housing, the fan unit including a radial or centrifugal fan. The fan housing includes an internal space that is partially enclosed and configured to accommodate at least a portion of the fan unit. The fan housing also includes: an inlet that is suitable for being connected to the dehumidifier so as to be able to draw dehumidified air into the internal space of the fan housing; and an outlet that is used to be able to dispatch dehumidified air from the internal space of the fan housing. The internal space of the fan housing has a generally U-shaped profile.

[0009] The present technology can make the fan configuration more effective, which improves the performance of the dehumidifier in combination with such fan configuration. In more detail, this realizes the effective configuration of the dehumidifier in combination with the fan assembly, which can provide (generate and dispatch) the uniform distribution (i.e., uniform airflow) of dehumidified air with the low energy consumption (e.g., power consumption) required to achieve this during operation (i.e., when the dehumidifier and the fan of the fan assembly connected to the dehumidifier operate together). In addition, this can also improve the accuracy of controlling the dehumidifier in combination with the fan assembly. In more detail, this is achieved by means of the configuration of the fan housing of the fan assembly, and in particular by means of a fan housing with an internal space (e.g., a chamber or box) for accommodating a radial or centrifugal fan, the internal space having a roughly U-shaped profile (e.g., a semi-vortex). Thus, when the fan of the fan assembly is operated to generate an overpressure in the internal space of the fan housing to be able to distribute the dehumidified air generated by the dehumidifier. This is achieved by reducing the pressure drop within the fan housing (i.e., within the interior space) compared to conventional fan housings, thereby reducing the energy consumption required to generate (i.e., establish) the overpressure. In particular, the reduction in pressure drop is achieved by virtue of the interior space of the fan housing not including any structure or insert (e.g., a structure or insert that causes the presence of an edge or protrusion within the interior space) that affects one or more air flows within the interior space (e.g., reduces the velocity of one or more air flows and thereby causes a pressure drop).

[0010] Suitably, the contour of the interior space of the fan housing defines a closed end and an open end opposite the closed end, wherein the outlet is arranged at the open end, and wherein the contour is bent at the closed end so that the contour is configured to include a curved portion having a certain curvature, while the remainder of the contour is configured to have substantially no curvature, and wherein the curvature of the curved portion has an angular extension corresponding to a central angle between radial lines extending from respective end points of the curved portion to a center position of the curvature and is configured to be substantially equal to or less than 180 degrees.

[0011] The inlet of the fan housing of the fan assembly can be arranged at a position of the closed end of the profile of the inner space of the fan housing. In these examples, the fan housing is configured to accommodate at least a part of the fan unit at a position of the closed end of the profile towards the inner space.

[0012] Preferably, the contour of the interior space of the fan housing extends to and terminates at the outlet.

[0013] In one example, the interior space of the fan housing is configured to accommodate the at least a portion of the fan unit such that a rotation axis of the fan unit extends substantially perpendicularly relative to a contour of the interior space.

[0014] Preferably, the inlet of the fan housing is configured for being able to draw dehumidified air (ie produced by the dehumidifier) ​​into the interior space substantially axially with respect to the axis of rotation of the fan unit.

[0015] The outlet of the fan housing may be arranged at a position in a radial direction relative to a rotation axis of the fan unit.

[0016] In one example, a portion of the inner space of the fan housing facing the outlet is further configured to be inclined inwardly in a direction perpendicular to the contour of the inner space so as to be able to deflect the dehumidified air passing through the outlet (ie, so as to be able to change its direction).

[0017] This enables flexibility in the connectivity of the dehumidifier for distributing dehumidified air via the outlet of the fan assembly coupled to the dehumidifier. In more detail, the dehumidifier can be connected to the duct system via the outlet of the fan housing (i.e., the dehumidifier is connected to the inlet of the fan housing so that the dehumidified air generated by the dehumidifier can be distributed to the outlet of the fan housing via the interior space of the fan housing), the duct system extends from the outlet in different directions (e.g., depending on the implementation requirements) without modifying the outlet, and at the same time maintains the desired air distribution (i.e., distribution of dehumidified air) capability in terms of delivering one or more air flows from the outlet to the duct system and further from the duct system to the desired distribution location.

[0018] Suitably, the interior space of the fan housing is formed by a first wall element having a profile forming a closed first end and an open second end opposite to the first end. In these examples, the interior space is also formed by a first pair of wall elements, the first pair of wall elements comprising a second wall element and a third wall element, the second wall element and the third wall element being configured to be parallel to each other and spaced apart from each other and arranged at and parallel to the corresponding edge segments at the second end of the first wall element, and extending straight along the direction from the first end to the second end. In these examples, the interior space is also formed by a second pair of wall elements, the second pair of wall elements comprising a fourth wall element and a fifth wall element, the fourth wall element and the fifth wall element being configured to be parallel to each other and spaced apart from each other, and arranged on opposite sides of the first wall element and the first pair of wall elements, wherein the first wall element and the first pair of wall elements and the second pair of wall elements are arranged to form an interior space, the interior space being configured to accommodate at least a portion of the fan unit, so that the axis of rotation of the fan unit extends in a direction substantially perpendicular to the second pair of wall elements. The profile of the first wall element is curved, and the first wall element and the first pair of wall elements together form a substantially U-shaped profile of the inner space.

[0019] Suitably, the interior space is also formed by a sixth wall element, which is arranged at an edge section of the fourth wall element facing away from the first end of the first wall element, wherein the sixth wall element is also arranged to extend beyond the fifth wall element in a direction from the first end to the second end of the first wall element and is inclined inwardly relative to the interior space.

[0020] The edge sections of the first pair of wall elements facing away from the closed end of the first wall element are adapted to meet the inwardly inclined sixth wall element.

[0021] Suitably, the sixth wall element is configured to be inclined inwardly in a direction towards the fifth wall element, such that the angle between the sixth wall element and a straight line extending perpendicularly from an edge segment of the first end of the fourth wall element facing away from the first wall element in a direction towards the fifth wall element is in the range of 10 to 80 degrees. Preferably, the angle is in the range of 30 to 60 degrees, even more preferably in the range of 40 to 50 degrees. The angle can be selected, for example, according to the application requirements in terms of the desired direction for distributing the dehumidified air (e.g., according to the direction of the duct system connected to the outlet of the fan housing).

[0022] In one example, the inlet of the fan housing is formed by a first aperture in the fourth wall element. In this example, the fifth wall element comprises a second aperture formed in the fifth wall element, the second aperture being configured for receiving at least a portion of the fan unit.

[0023] Suitably, the second aperture in the fifth wall element configured for receiving at least a portion of the fan unit is configured to be offset relative to the contour of the interior space in a direction towards the first end of the first wall element and in a direction towards one of the second wall element or the third wall element.

[0024] Suitably, the second aperture and the first aperture are aligned relative to each other.

[0025] Suitably, the fan housing is configured for mounting into an external enclosure (eg an external enclosure suitable for coupling a fan assembly including the fan and fan housing to a dehumidifier).

[0026] Suitably, at least a portion of the fan unit comprises an impeller of the fan unit and at least a portion of a motor coupled to the impeller of the radial fan.

[0027] Suitably, the dehumidifier is configured to be mounted to a duct system via an outlet of a fan housing of a fan assembly, the duct system extending outwardly from the outlet of the fan housing in a direction parallel to the contour of the interior space of the fan housing, in a direction perpendicular to the contour of the interior space, or in a direction defined by an angle between a direction parallel to the contour of the interior space of the fan housing and a direction perpendicular to the contour of the interior space.

[0028] Preferably, the fan unit of the fan assembly comprises an electronically commutated EC motor. Such a motor is advantageously used to further reduce the power consumption for operating the fan of the fan assembly, which thereby also reduces the overall power consumption of the integrated configuration (i.e. the dehumidifier combined with the fan assembly). This reduction is particularly significant compared to the conventional use of an alternating current AC motor to operate the fan unit.

[0029] Preferably, the fan assembly is of a type comprising a radial fan or a centrifugal fan.

[0030] According to another aspect of the utility model, a dehumidifier having such a fan assembly is provided.

[0031] The effects and features of this aspect (ie, the aspect associated with the dehumidifier) ​​are largely similar to those described above in conjunction with the aspect associated with the fan assembly. The aspects mentioned in relation to the dehumidifier are largely compatible with the aspects associated with the fan assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Figure 1A to Figure 1B A dehumidifier provided with a fan assembly and a fan assembly for (to be used with) the dehumidifier according to respective aspects of the present invention are schematically illustrated in a perspective view and a corresponding exploded perspective view.

[0050] ( Figure 1A The dehumidifier 5 (partially shown in FIG. 1 ) is configured to produce dehumidified air. Suitably, the dehumidifier 5 is configured as a desiccant dehumidifier.

[0051] like Figure 1A As shown in FIG. 1 , the dehumidifier 5 is configured to be connected to a fan assembly 110 (in Figure 1A 110 is shown assembled within the outer enclosure 3) for distributing the dehumidified air generated by the dehumidifier via the fan assembly (i.e., so that the dehumidified air generated by the dehumidifier can be distributed to one or more desired locations, such as locations remote from the dehumidifier location). In other words, the fan assembly 110 is configured for use with the dehumidifier. Suitably, the dehumidifier 5 is configured to be mounted to a duct system for this purpose via the fan assembly 110, as shown in reference to FIG. 3A to FIG. 3E Described in more detail.

[0052] In addition, if Figure 1B As shown in FIG. 1 , a fan assembly 110 (suitable for use with a dehumidifier) ​​includes a fan housing having an interior space 20 that is partially enclosed and has a generally U-shaped profile. The generally U-shaped interior space 20 is formed by a set of wall elements (which are part of the fan housing) that together form a fan housing. FIG. 3A to FIG. 3E The substantially U-shaped internal space 20 shown, FIG. 3A to FIG. 3E A similar configuration is shown for a fan housing with associated wall elements. Figure 2B The generally U-shaped interior space 20 is described in more detail. Figure 2B Illustration of the profile used for the interior space Figure 1B The fan housing of the fan assembly 110 also includes an inlet 24 (i.e., the inlet 24 formed by the first orifice 17) and an outlet 25, the inlet 24 and the outlet 25 being respectively used to be able to draw dehumidified air (i.e., the dehumidified air produced by the dehumidifier) ​​into the interior space 20 and to be able to dispatch the dehumidified air from the interior space 20. Thus, the inlet of the fan housing of the fan assembly is connected to the dehumidifier to be able to receive the dehumidified air produced by the dehumidifier. The fan assembly 110 also includes a fan unit (i.e., a unit with an associated motor 85, and the unit includes an impeller 80 or a fan wheel with one or more fan blades 81). The fan unit includes a radial fan or a centrifugal fan. The fan unit is configured to be installed in the fan housing. In particular, the internal space is configured to accommodate at least a portion of the fan unit included in the fan assembly (e.g., such as Figure 1B , wherein at least a portion of the fan unit including a motor 85 coupled to an impeller or fan wheel 80 is mounted in a fan housing, the impeller or fan wheel 80 including one or more fan blades 81). Preferably, at least a portion of the fan unit is accommodated within the interior space 20 of the fan housing, such that the axis of rotation R1 of the fan unit is perpendicular to the U-shaped profile of the interior space. For this purpose, the fan housing includes a second aperture 18 configured to receive the fan unit.

[0053] like Figure 1B As also shown in FIG. 1 , the set of wall elements of the fan housing includes: a first wall element 10; and a first pair of wall elements 14, the first pair of wall elements 14 including a second wall element 14a and a third wall element 14b; and a second pair of wall elements 15, the second pair of wall elements 15 including a fourth wall element 15a and a fifth wall element 15b. The first wall element and the first pair of wall elements and the second pair of wall elements together form a substantially U-shaped internal space 20, as shown below in combination Figure 3A For more detailed discussion, Figure 3AA similar configuration is shown for a fan housing with associated wall elements. Figure 1B As shown in FIG. , the set of wall elements also includes reference FIG. 3A to FIG. 3B and Figure 3D The sixth wall element 16 is described in more detail.

[0054] As described above, the fan unit of the fan assembly 110 has an associated motor 85 (ie, a motor coupled to the fan unit). Preferably, the fan unit of the fan assembly 110 comprises an electric motor (ie, a motor such as Figure 1A to Figure 1B , where the motor 85 is illustrated as an electric motor). Even more preferably, the electric motor corresponds to an electronically commutated EC motor. Alternatively, the electric motor is selected from one or more other types of electric motors other than EC motors, such as one or more other types of electric motors corresponding to alternating current AC motors or direct current DC motors.

[0055] Preferably, the fan assembly 110 is a type corresponding to a radial fan or a centrifugal fan. For example, the fan unit (ie, the fan unit of the fan assembly) may include a radial fan having an impeller 80 (eg, an impeller or fan wheel having one or more fan blades 81).

[0056] Suitably, the fan assembly further comprises one or more mounting elements for mounting the fan unit to a fan housing of the fan assembly and / or for facilitating connection of the fan assembly to other external devices (i.e., such as Figure 1A The dehumidifier 5 shown in FIG. Figure 1B As shown in , the fan assembly includes a first annular mounting element AM1 for mounting the fan unit to the fifth wall element 15b so that at least a portion of the fan unit is accommodated within the interior space 20 and so that the rotation axis R1 of the fan unit extends in a direction perpendicular to the generally U-shaped profile of the interior space. Figure 1B As shown in FIG. 1 , the fan assembly 110 includes a second annular mounting element AM2 configured to be arranged at the inlet 24 (eg, along the periphery of the inlet) (eg, along the configuration as defined by Figure 1B and Figure 3A The second annular mounting element AM2 is configured to facilitate connecting the inlet 24 of the fan assembly 110 to an external device (i.e., a dehumidifier) ​​so that the dehumidified air generated by the dehumidifier can be transported and distributed to one or more desired locations (for example, a location away from the dehumidifier and the fan assembly to which the dehumidified air can be transported via a duct system connected to the outlet of the fan assembly).

[0057] Appropriately and as Figure 1A to Figure 1B As shown in FIG. 1 , the fan assembly 110 is configured to be installed in the external enclosure 3. Preferably, the external enclosure 3 is configured to be installed on an external device (ie, Figure 1A The dehumidifier 5 shown in FIG. Figure 1A to Figure 1B As shown in , the outer enclosure 3 comprises a support bracket 135 mounted to the bottom plate 100c and two pairs of wall elements mounted to the bottom plate 100c. Figure 1A As shown in FIG. 1 , the two pairs of wall elements of the external enclosure include a third pair of wall elements and a fourth pair of wall elements, the third pair of wall elements are configured as side walls including a first side wall element 100a and a second side wall element 100b, and the fourth pair of wall elements are configured as a rear wall and a front wall including a rear wall element 100d and a front wall element 100e, respectively. The external enclosure 3 also includes a top wall element 120 (e.g., corresponding to FIG. Figure 3A The outlet mounting frame element 25a shown in the figure has a top wall element 120 having a centrally arranged orifice (for example, an orifice having a rectangular shape or other suitably constructed shape, configured to constitute the outlet 25 or configured to be sized to fit the outlet 25), and the top wall element 120 is also configured to be covered by a perforated protective structure 115 (for example, a grille) to allow air distributed via the outlet to pass through.

[0058] Figure 1C A side view of the fan assembly 110 is shown, and Figure 1D A front view of a fan assembly is shown, wherein for illustration purposes, the outline of the interior space of the fan housing and the airflow associated with the fan assembly when the fan assembly is in operation (i.e., when the fan unit is enabled and moving air, i.e., dehumidified air) are visible. Figure 1C As shown in FIG. 1 , the fan assembly 110 is configured to move the dehumidified air in a first direction 60 (ie, via the inlet 24 in a direction relative to the Figure 1B ) into the inner space, and is also configured to move the dehumidified air in a second direction 66 (corresponding to the dehumidified air passing through the inner space by the fan unit). FIG. 2D to FIG. 2E Alternatively, the fan assembly 110 is configured to distribute the dehumidified air in a radial direction relative to the rotation axis of the fan unit (e.g., in a radial direction such as Figure 2A 65 as shown in the figure) or in an inclined direction, i.e. an angled direction relative to the radial direction of the rotation axis R1 of the fan unit, such as in a direction inclined at an angle between the radial direction of the rotation axis R1 of the fan unit and the axial direction of the rotation axis R1 of the fan unit, from the interior space via the outlet 25. This can be done, for example, by configuring the interior space 20 of the fan housing of the fan assembly 110 so that it does not include an inwardly inclined portion 21 (e.g., as FIG. 2A to FIG. 2C) or alternatively by Figure 3D This can be achieved by a suitable configuration of the angle a1 associated with the inclination of the sixth wall element shown in FIG. Figure 1D As shown in FIG. 1 , the fan assembly is configured to impart rotational motion to the dehumidified air sucked into the interior space of the fan housing, so that the dehumidified air in the interior space flows along the third direction 70. It should be noted that, depending on the configuration of the fan unit in terms of the rotational motion direction of the axis of the fan unit, the air in the interior space (i.e., the dehumidified air) may also flow in a direction that is parallel to the direction of rotation of the axis of the fan unit. Figure 1D The flow is in the opposite direction of direction 70 shown in FIG.

[0059] Suitably, one or more wall elements of the fan housing form part of the outer enclosure 3. For example, Figure 1B As shown in FIG. 1 , the second pair of wall elements 15 comprising the fourth wall element 15a and the fifth wall element 15b respectively form the rear wall and the front wall of the outer enclosure 3, whereby the outer enclosure does not need to be as Figure 1A Such corresponding individual wall elements 100d to 100e are shown in FIG.

[0060] For illustrative purposes, Figure 1B As shown in Figure 1A The fan housing of the fan assembly 110 shown in FIG. 1 as being coupled to the dehumidifier has been illustrated as being connected to the fan assembly 110 of the dehumidifier. Figure 3A The fan housing shown in FIG. 1 is constructed in a similar manner, that is, the set of wall elements including the first wall element 10 and the first pair of wall elements 14 and the second pair of wall elements 15 together form a substantially U-shaped interior space 20. In addition, Figure 1B The fan assembly shown in has been illustrated such that the set of wall elements comprises a sixth wall element 16 and such that the fan assembly comprises annular mounting elements AM1 and AM2, respectively. In addition, Figure 1A to Figure 1B The fan assembly 110 shown in FIG has been illustrated as being enclosed within a protective enclosure 3. However, it should be noted that the fan assembly 110 shown in FIG1A and FIG1B , respectively, is enclosed within a protective enclosure 3. Figure 1B The fan assembly 110 in the embodiment of the present invention can be configured differently. In particular, the fan housing of the fan assembly can be configured according to the embodiment of the present invention. FIG. 2A to FIG. 2E or FIG. 3A to FIG. 3E For example, a fan housing of a fan assembly including a generally U-shaped interior space can be constructed by means of one or more appropriately constructed structural elements that together form a generally U-shaped interior space, for example, as combined with a fan housing having a generally U-shaped interior space. FIG. 2A to FIG. 2E The configuration of the fan housing 50 shown in FIG. 5 is discussed. In addition, the interior space of the fan housing can be arranged according to the FIG. 2A to FIG. 2C The configuration of the fan housing 50 shown (i.e., without FIG. 2D to FIG. 2EIn addition, the fan assembly can be constructed without a separate external enclosure. For example, the structural elements and / or wall elements constituting the fan housing can be appropriately configured so that a separate external enclosure becomes unnecessary. In addition, depending on the configuration of the internal space of the fan housing (i.e., depending on whether the internal space is configured to include an inwardly inclined portion), the direction in which the air is distributed through the outlet can be different from Figure 1C For example, air can be directed in the direction shown in FIG. FIG. 2A to FIG. 2C The illustrated fan housing 50 is shown in a fourth direction 65. Furthermore, the fan assembly may be constructed without the sixth wall element 16 and / or without the corresponding annular mounting elements AM1 and AM2.

[0061] FIG. 2A to FIG. 2E Schematically illustrates a suitable Figure 1A and Figure 1B A fan housing configuration is described that is configured as part of a fan assembly 110 for use with a dehumidifier.

[0062] Figure 2A 2 is a perspective view illustrating a fan housing (ie, fan housing 50) including an internal space 20 according to the second aspect. The outline of the internal space 20 is generally U-shaped. Figure 2B , and the contour of the inner space 20 of the fan housing 50 has the same Figure 1B The interior space 20 shown in the fan housing of the fan assembly 110 has the same characteristics in terms of outline. The interior space 20 (e.g., a chamber or box) is partially enclosed (i.e., the interior space is partially enclosed by means of the fan housing) and is configured to accommodate a fan unit including a centrifugal or radial fan (i.e., as for Figure 1A and Figure 1B The fan housing 50 also (similar to Figure 1B ) includes an inlet 24 and an outlet 25, respectively for enabling air (i.e., dehumidified air) to be drawn into the interior space 20 (e.g., along a first direction 60) and for enabling air (i.e., dehumidified air) to be dispatched from the interior space 20 (e.g., along a fourth direction 65 different from the second direction 66). The generally U-shaped interior profile 20 of the fan housing 50 is constructed by means of one or more appropriately constructed structural elements, which together form a generally U-shaped interior space.

[0063] The inlet 24 is formed by the first aperture 17 and extends through the fan housing 50 so as to be able to draw air (ie dehumidified air) into the interior space.

[0064] For the purpose of enabling the internal space of the fan housing to be configured to accommodate at least a portion of the fan unit, the fan housing includes a second aperture 18 (i.e., an aperture extending through the fan housing), which is configured to receive at least a portion of the fan unit. In more detail, the fan housing may be configured to receive at least a portion of the fan unit into the internal space through the second aperture (e.g., an aperture or opening having a suitable shape such as a circular, oval or rectangular shape), such as Figure 2A As shown in , at least a portion of the fan unit (for example, the fan unit includes Figure 1B An impeller or a portion of a fan wheel 80 having one or more fan blades 81 as shown in FIG. 1 can be accommodated within the interior space of the fan housing, and at least a portion of the motor of the fan unit extends outwardly through the aperture 18 (e.g., as shown in FIG. 1 ). Figure 1A to Figure 1B , where at least a portion of a motor 85 of the fan unit extends outwardly from the fan housing through the second aperture 18 ).

[0065] like Figure 2A As also shown in FIG. 1 , the internal space is configured to accommodate at least a portion of the fan unit so that the rotation axis R1 of the fan unit extends perpendicularly or substantially perpendicularly relative to the profile of the internal space 20 (i.e., relative to a portion of the internal space extending along a cross-sectional plane CS of the internal space, along which the internal space is configured to define a substantially U-shaped profile). Figure 2B is shown in more detail in .

[0066] Figure 2B The fan housing is shown in a generally U-shaped outline P (ie, Figure 2A The inner space of the fan housing shown in FIG. Figure 2A , Figure 2C and Figure 2D In other words, the internal space is formed in the fan housing, and the cross section of the fan housing across the flow direction thereof has a profile (internal profile) that forms a substantially U-shaped internal space. It should be noted that Figure 1B The inner space of the fan assembly shown in FIG. 1 also has the same inner contour as that of the fan assembly shown in FIG. Figure 2A The same characteristics as described above for the internal space associated with the fan housing 50 shown in FIG. Although the profile P has been described as being generally U-shaped, the profile of the internal space may also be U-shaped. Figure 2BAs also shown in FIG. 1 , the profile of the interior space 20 defines a closed end 11 and an open end 12 opposite the closed end 11. The outlet 25 is arranged at the open end 12 of the U-shaped profile P. Suitably, in order to construct the substantially U-shaped profile of the interior space, the profile (or cross section) of the interior space is configured to be curved at the closed end 11 (for example, by means of one or more appropriately configured structural elements that together form the substantially U-shaped interior space, or by means of reference Figure 1B and Figure 3A The inner space is preferably configured such that a portion of the contour is curved and defined by a certain curvature, the curvature comprising a curvature defined by an arc or a semicircle. Thus, the inner space is configured such that it has a curved surface at the closed end that faces away from the open end. The inner space is also appropriately configured such that it has a flat surface at the open end, the flat surface having an opening suitable for forming the outlet 25 of the fan housing and / or connecting with the outlet 25 of the fan housing. Preferably, the contour of the inner space is configured to be curved at the closed end such that the contour is configured to include a curved portion having a certain curvature (extending between the corresponding end points EP1 and EP2 of the curved portion of the contour of the inner space), while the rest of the contour of the inner space is configured to have substantially no curvature. Preferably, the curvature of the curved portion has an angular extension configured to be substantially equal to or less than 180 degrees (i.e., an angular extension corresponding to a central angle CA between radial lines extending from the corresponding end points EP1 and EP2 of the curved portion of the contour of the inner space to a center position CCL of curvature associated with the curvature). Suitably, the angular extension (ie the central angle) is configured to be substantially equal to 180 degrees or to be within a range between 160 degrees and 180 degrees.

[0067] The above configuration of the fan housing 50 and the reference Figure 1B and FIG. 3A to FIG. 3E The configuration of the fan housing including the profile of the interior space having a generally U-shaped profile realizes a semi-vortex type vortex housing design. In other words, in terms of angular extension, the curvature of the profile of the interior space 20 is generally limited to a maximum of 180 degrees, that is, the curvature generally does not extend beyond 180 degrees. Therefore, the configuration of the fan housing 50 including the generally U-shaped profile of the interior space is different from the conventional configuration of the fan housing including a conventional fan vortex housing (e.g., full vortex type or similar), which generally realizes a spiral or volute design for the interior space, wherein the corresponding profiles (i.e., cross-sections) for such conventional configurations each have a curvature (in the form of a single continuous curvature or in the form of a total curvature for multiple curved sub-segments) that is generally greater than 180 degrees.

[0068] During operation, i.e. when the housing of the fan unit has a rotation axis R1 extending substantially perpendicularly relative to the contour of the interior space 20 and when the fan unit is operating, a rotating airflow is generated within the interior space 20 (e.g. Figure 1D , or a rotating airflow in a direction opposite to direction 70 depending on the configuration of the rotational movement direction of the fan unit).

[0069] Figure 2C The diagram shows how FIG. 2A to FIG. 2B The side view of the inner space of the fan housing 50 is shown. Figure 2C and similar to Figure 1B As shown in the fan housing of FIG. 5 , the inlet 24 of the fan housing 50 is arranged at a position of the closed end 11 of the contour facing the internal space 20. In more detail, the fan housing is configured so that the distance d1 between the closed end 11 of the internal space and the center point (not shown) of the inlet 24 is smaller than the distance d2 between the open end 12 of the internal space and the center point of the inlet. Figure 2C As shown in FIG. 1 , the fan housing 50 is configured to accommodate at least a portion of the fan unit at a position of the closed end 11 contour facing the interior space 20 (ie, as shown in FIG. 1 ). Figure 2C , in which the orifice 18 and / or the axis of rotation indicated for the fan unit are located towards the closed end 11 of the interior space).

[0070] like Figure 2C As also shown in FIG. 1 , the inlet 24 of the fan housing is configured to be able to draw air (i.e., dehumidified air) into the interior space 20 substantially axially relative to the rotation axis R1 of the fan unit (when the fan unit is accommodated in the interior space of the fan housing, i.e., similar to the case for Figure 1B , wherein the fan housing accommodates at least a portion of the fan unit), i.e. Figure 2C 60, which represents the first direction 60 of the air inflow extending axially relative to the rotation axis R1. Alternatively, the inlet 24 may be positioned in a direction different from that represented by Figure 2A and Figure 2C For example, the inlet may be positioned at a position capable of drawing air into the interior space substantially perpendicularly relative to the rotation axis R1 of the fan unit.

[0071] Furthermore, the outlet 25 is arranged at a position in the radial direction relative to the rotation axis R1 of the fan unit, and the internal space is configured to accommodate the fan unit (ie, similar to the Figure 1B The content shown in the fan assembly shown in , where the outlet is arranged in a radial direction relative to the rotation axis of the fan unit).

[0072] Figure 2D and Figure 2E The third aspect is illustrated and an alternative configuration of the interior space 20 of the fan housing 50 is shown in side view and perspective view respectively (by FIG. 2A to FIG. 2C This alternative configuration of the interior space of the fan housing corresponds to Figure 1B The interior space of the fan housing of the fan assembly 110 shown in FIG. Figure 3A The configuration of the inner space of the fan housing 50 shown in FIG. FIG. 2D to FIG. 2E In the alternative configuration shown in FIG. 2 , a portion 21 of the interior space 20 facing the outlet 25 (i.e., an upper portion of the interior space adjacent to the outlet) is also configured to be inclined inwardly. More specifically, the portion 21 of the interior space is configured to be inclined inwardly in a direction perpendicular to the contour of the interior space 20 so as to be able to deflect the air passing through the outlet 25 (i.e., to make the air flow in a direction such as FIG. 2D to FIG. 2E The second direction 66 shown in FIG. 1 is distributed through the outlet, and wherein the second direction 66 is different from the second direction 66 for FIG. 2A to FIG. 2C In more detail, the inwardly inclined portion 21 of the interior space 20 is configured such that the upper portion of the interior space is inclined inwardly at (e.g., from) the opposite side of the outline of the interior space (i.e., at the opposite side of the cross section CS of the interior space), and such that the inwardly inclined portion includes a first inwardly inclined sub-portion (not shown) facing the fan housing and enclosed by the fan housing, and a second inwardly inclined sub-portion (not shown) facing the fan housing and enclosed by the fan housing portion, and wherein the outlet is arranged at the second inwardly inclined sub-portion. Preferably, with the configuration for FIG. 2D to FIG. 2E The outlet 25 associated with the fan housing shown has a rectangular shape (eg Figure 2E ) or other suitable shapes. It should be noted that FIG. 2D to FIG. 2E The interior space 20 shown is substantially the same as that described above for the embodiment according to the invention except that it has an inwardly inclined portion 21. FIG. 2A to FIG. 2C The interior space of the example shown is constructed in a similar manner as discussed above.

[0073] like FIG. 2A to FIG. 2C and FIG. 2D to FIG. 2E As shown in FIG. 1 , the contour of the interior space 20 extends to and terminates at the outlet 25 (i.e., similar to Figure 1B The interior space of the fan housing of the fan assembly shown in FIG.

[0074] Figure 3A Shows FIG. 2D to FIG. 2E , wherein the interior space 20 is formed by wall elements (i.e., similar in configuration to that for Figure 1B ).

[0075] like Figure 3A As shown in FIG. 1 , the fan housing 50 includes a set of wall elements that together form an interior space 20, which is partially enclosed (i.e., the interior space is partially enclosed by the set of wall elements) and is configured to accommodate at least a portion of the fan unit. In more detail, the interior space 20 is formed by a first wall element 10 having a profile that forms a closed first end and an open second end opposite the first end (i.e., as shown in FIG. 1 ). Figure 3E The first end 8 and the second end 9 shown in FIG. Figure 3E The fan housing is shown along the Figure 3A The interior space 20 is also formed by a first pair of wall elements 14, which includes a second wall element 14a and a third wall element 14b, which are configured to be parallel to each other and spaced apart from each other, and are arranged at corresponding edge sections at the second end 9 of the first wall element 10 (i.e., as shown in FIG. 1 ). Figure 3E The inner space 20 is also formed by a second pair of wall elements 15, which include a fourth wall element 15a and a fifth wall element 15b (as shown in FIG. FIG. 3B to FIG. 3C As shown in Figure 3B and Figure 3C Corresponding front views of the fourth wall element 15a and the fifth wall element 15b are respectively illustrated, the fourth wall element 15a and the fifth wall element 15b are constructed to be parallel to each other and spaced apart from each other, and are arranged on opposite sides of the first wall element 10 and the first pair of wall elements, wherein the first wall element 10 and the first pair of wall elements 14 and the second pair of wall elements 15 are arranged to form an internal space 20 and are constructed to accommodate at least a portion of the fan unit, so that the rotation axis R1 of the fan unit extends in a direction substantially perpendicular to the second pair of wall elements 15.

[0076] The profile of the first wall element 10 is curved, and the first wall element 10 and the first pair of wall elements 14 together form a substantially U-shaped profile of the inner space 20. The wall element 15 may be formed of a metal sheet or other suitable material.

[0077] The profile of the first wall element 10 also extends (ie in addition to extending along the substantially U-shaped profile) for a certain distance (ie, as shown in FIG. 1 ) in a direction perpendicular to the profile of the first wall element (ie, perpendicular to the cross-sectional plane CS). Figure 3A and Figure 3D The distance d5 shown in Figure 3D It shows that Figure 3A). The distance d5 is configured to roughly correspond to the distance between the second pair of wall elements 15, so that the first wall element is connected to the spaced fourth wall element and the fifth wall element of the second pair of wall elements (that is, so that the first wall element and the second pair of wall elements jointly enclose the internal space located between the first wall element and the second pair of wall elements). Similarly, at least a portion of the second wall element and the third wall element of the first pair of wall elements also extend the distance d5 in a direction perpendicular to the contour of the first wall element (that is, so that the first wall element and the first pair of wall elements jointly enclose the internal space located between the first wall element and the first pair of wall elements).

[0078] like Figure 3A As also shown in FIG. 1 , the fan housing further comprises a sixth wall element 16 (eg Figure 3B and Figure 3D as well as Figure 1B The sixth wall element 16 is arranged at an edge section of the fourth wall element 15a (i.e., an edge section facing away from the first end 8 of the first wall element 10). The sixth wall element 16 is also arranged along a direction 51 from the first end 8 to the second end 9 of the first wall element 10 (as shown in FIG. Figure 3E ) extends beyond the fifth wall element 15b (ie, as shown in Figure 3A and Figure 3D , wherein the distance d3 corresponding to the total height of the fourth wall element and the sixth wall element when connected together is greater than the distance d4 corresponding to the height of the fourth wall element). In addition, the sixth wall element is arranged to be inclined inwardly relative to the interior space 20 (as shown in FIG. Figure 3A ).

[0079] The fan housing 50 is configured such that the edge section of the first pair of wall elements 14 facing away from the closed end 8 of the first wall element 10 is adapted to meet the inwardly inclined sixth wall element 16. For example, the end portion of the first pair of wall elements may be inclined inwardly relative to the interior space 20 so that the edge section thereof is adapted to meet the inwardly inclined sixth wall element 16. In some examples, the end portion has a generally triangular shape (e.g., as Figure 3A and Figure 3D , in which the end portions of the second wall element and the third wall element facing the sixth wall element each have a substantially triangular shape).

[0080] The sixth wall element 16 is arranged to be inclined inwardly at an angle a1 (eg Figure 3D). In more detail, the sixth wall element is configured to be inclined inwardly in the direction toward the fifth wall element. Thus, an angle a1 is formed between the sixth wall element and a straight line L1, which extends vertically from an edge section of the first end of the fourth wall element facing away from the first wall element in the direction toward the fifth wall element. Suitably, the angle a1 is configured to be in the range of 10 to 80 degrees. Preferably, the angle a1 is in the range of 30 to 60 degrees, or even more preferably in the range of 40 to 50 degrees (e.g., 45 degrees).

[0081] It should be noted that Figure 3A The fan housing 50 - although the fan housing is shown as having a similar Figure 1B and FIG. 2D to FIG. 2E The interior space of the interior space structure shown - alternatively, it can be configured as for Figure 2A The fan housing is as discussed above (i.e., it does not have FIG. 2D to FIG. 2E ), and the fan housing resulting from this configuration can be implemented for being connected to the fan assembly 110 of the dehumidifier 5. For this configuration of the fan housing 50 (i.e., wherein the fan housing is configured to have an inner space 20 without an inwardly inclined portion 21, for example, as FIG. 2A to FIG. 2C As illustrated), the configuration of the fan housing including the set of wall elements may not include the sixth wall element 16, and the entire second wall element 14a and the third wall element 14b may be respectively configured to extend the entire distance d5 along a direction perpendicular to the profile.

[0082] Also refer to Figure 3A , the inlet 24 is formed by the first opening 17 in the fourth wall element 15a (ie, Figure 3A and Figure 3B In addition, the fifth wall element 15b is configured to include a second aperture 18 (ie, the second aperture is formed in the fifth wall element 15b, as shown in FIG. 1 ). Figure 3A and 3C ), the second aperture 18 is configured to receive at least a portion of a fan unit (e.g., Figure 1B ).

[0083] Appropriately, such as FIG. 3B to FIG. 3C As shown in FIG. 1 , the first orifice 17 and the second orifice 18 are configured off-center, ie, at a first offset distance OD1 and a second offset distance OD2 , respectively, relative to a center position CL of a profile P of the interior space 20 .

[0084] In more detail, and as Figure 3CAs shown in FIG. 1 , the second aperture 18 in the fifth wall element 15 b configured to receive at least a portion of the fan unit is further configured in a direction toward the first end 8 of the first wall element 10 and in a direction toward one of the second wall element 14 a and the third wall element 14 b (as shown in FIG. 1 ). Figure 3E ) is offset from the center relative to the contour of the interior space 20 (i.e., as shown in Figure 3C , where the second orifice 18 is configured to be included at a distance for illustrative purposes. Figure 3C At the center position C1 of the contour P in the second offset distance OD2, the contour P corresponds to a substantially U-shaped contour of the interior space 20 formed by the first wall element and the first pair of wall elements and the second pair of wall elements, such as Figure 3A and Figure 3E ).

[0085] Preferably, the second orifice 18 and the first orifice 17 are aligned relative to each other. Figure 3B As shown in , the first aperture 17 of the fourth wall element 15a is configured within the fourth wall element and similarly to what has been discussed above for the second aperture within the fifth wall element at a first offset distance OD1. Thus, by configuring the first offset distance OD1 for the first aperture to correspond to the second offset distance OD2 for the second aperture, the respective first aperture and second aperture become aligned (i.e., aligned when the first wall element and / or the first pair of wall elements and the second pair of wall elements are joined together to jointly form the interior space 20). Alternatively, the first aperture and the second aperture are aligned relative to each other (i.e., when the fourth wall element and the fifth wall element are arranged parallel to each other and spaced apart from each other) without being offset by the respective offset distances relative to the center position CL.

[0086] Suitably, the fan housing 50 is configured to be mounted to an external enclosure (e.g., such as Figure 1A and Figure 1B Suitably for this purpose, one or more of the wall elements of the fan housing 50 are configured to form part of the outer enclosure (e.g., wall elements 15a and 15b may be configured to form part of the outer enclosure 3, such as Figure 1B ).

[0087] Preferably, at least a portion of the fan unit (i.e., at least a portion of the fan unit configured to be received within the interior space of the fan housing) includes an impeller of the fan unit and at least a portion of a motor coupled to the impeller of the fan unit (e.g., an impeller or fan wheel 80 of a radial or centrifugal fan and at least a portion of a motor 85 associated with the fan unit, such as Figure 1B ).

[0088] The fan housing 50 is configured for mounting to an air handling device (ie, Figure 1A Dehumidifier in 5).

[0089] Preferably, with respect to Figure 1B Similar to what is described about the fan housing of the fan assembly 110 shown in , the fan housing 50 is configured to be mounted to a duct system (not shown) via the outlet 25. In more detail, the fan housing 50 is configured to be mounted to the following duct system via the outlet 25: the duct system extends outward from the outlet 25 in a direction parallel to the outline of the interior space 20, in a direction perpendicular to the outline of the interior space 20, or in a direction defined by an angle between a direction parallel to the outline of the interior space 20 and a direction perpendicular to the outline of the interior space 20.

[0090] Suitably, the fan housing 50 (eg Figure 3A ) also includes an outlet mounting frame element 25a, which is configured to facilitate the installation of a perforated structure (e.g., Figure 1B The protective grille 115 shown in FIG.
