Description

TECHNICAL FIELD

[0001] The utility model relates to an air treatment equipment panel, panel assembly and air treatment system. BACKGROUND

[0002] In the past, there is an air treatment equipment panel, comprising: a panel frame provided with an air outlet duct, the downstream end of the air outlet duct on the flow path of the airflow flowing through the air outlet duct constitutes an air outlet; and a vane provided in the air outlet duct, extending along the length direction of the air outlet, provided with a shaft portion, and rotatably supported on the panel frame via the shaft portion.

[0003] In the above-mentioned air treatment equipment panel, in order to easily guide the airflow blown out from the air outlet to different directions, a driving part for driving the vane to rotate around the shaft portion can be considered to be provided on the panel frame.

[0004] However, in practice, when the vane rotates, the appearance at the air outlet of the air treatment equipment panel changes accordingly, so even if the air treatment equipment panel is roughly consistent with the style of the surrounding ceiling or the like when the vane is at a certain rotation angle, when the vane is at other rotation angles, the air treatment equipment panel and the surrounding ceiling or the like will become inconsistent in style, thereby affecting the overall aesthetic appearance.

[0005] In addition, for example, when the above-mentioned air treatment equipment panel is arranged on the top of the room with the air outlet facing the horizontal direction, the vane cannot guide the airflow blown out from the air outlet to a far place in multiple directions. SUMMARY

[0006] In view of the above problems, one object of the utility model is to provide an air treatment equipment panel, which can easily ensure that the overall appearance does not change substantially even when the vane rotates, thereby improving the aesthetic appearance during operation.

[0007] In addition, another object of the utility model is to provide an air treatment equipment panel, which helps to guide the airflow blown out from the air treatment equipment panel to a farther place in multiple directions or to guide the airflow flowing to the inside of the air treatment equipment panel earlier.

[0008] In addition, another object of the utility model is to provide a panel assembly comprising the above-mentioned air treatment equipment panel and an air treatment system comprising the above-mentioned air treatment equipment panel or the above-mentioned panel assembly.

[0009] To achieve the above object, the utility model provides an air treatment equipment panel, include: panel frame, the panel frame is equipped with the air -flow blows the air port, and at least one first blade, this first blade is along the length direction of air port is arranged, is equipped with first axle part, and can rotatably support in the panel frame through the first axle part, wherein, the panel frame has at least one fixed grid bar at the air port, this grid bar is along the length direction of air port is arranged, the first blade is compared in the air -flow flowing direction upstream with the grid bar, the panel frame still includes at least one second blade, this second blade is along the width direction of air port is arranged, and compared in the air -flow flowing direction upstream with the first blade.

[0010] Here, according to the length, width size of air port, the length, quantity of first blade and second blade can be adjusted.For example, when the first blade is formed continuously along its length direction, the size of the first blade in the length direction of the air port can be adjusted to adapt to the length of the air port, when the first blade is spliced by multiple segments arranged along its length direction, the number and length of the segments can also be adjusted to adapt to the length of the air port, and the number of the first blade in the width direction of the air port can also be adjusted to adapt to the width of the air port.Similarly, the number of the second blade in the length direction of the air port can be adjusted to adapt to the length of the air port, in particular, when the second blade is modularly formed into multiple second blade groups by being divided into multiple groups in the length direction of the air port, the number of the second blade groups and the number of the second blade in each second blade group can also be adjusted to adapt to the length of the air port, and the number of the second blade in one second blade group can be the same as or different from the number of the second blade in another second blade group.

[0011] According to the air treatment equipment panel of the utility model, the panel frame has at least one fixed grid bar at the air port, the grid bar is arranged along the length direction of the air port, the first blade is upstream (i.e. close to the inner side of the panel frame) in the air-flow flowing direction compared with the grid bar, the panel frame further includes at least one second blade, the second blade is arranged along the width direction of the air port, and is upstream (i.e. close to the inner side of the panel frame) in the air-flow flowing direction compared with the first blade, therefore, even if the first blade needs to be rotated, the rotation of the first blade will not be easily perceived due to the shielding of the grid bar, the change of the appearance at the air port of the air treatment equipment panel is inhibited, thereby, the flow direction of the air flow can be changed in multiple directions by the first blade and the second blade, at the same time, it is easy to ensure that the appearance of the air treatment equipment panel is basically unchanged, that is, the rotation of the internal blade does not affect the overall beauty of the external grid in vision, the indoor decoration consistency can be maintained and the air flow guiding can be carried out, and the beauty and function are taken into account.

[0012] Further, in the panel for air handling equipment, preferably, the first shaft part of the at least one first blade is aligned with the grid bars in the width direction of the air outlet.

[0013] Here, the first shaft part of the at least one first blade being aligned with the grid bars means that the at least one first blade is at the same height as the grid bars, or approximately at the same height (for example, the height difference is within a preset range).

[0014] According to the panel for air handling equipment, the first shaft part of the at least one first blade is aligned with the grid bars in the width direction of the air outlet, so that the rotation of the first blade is not easily perceived due to the shielding of the grid bars, thereby improving the visual effect; on the other hand, since the first blade and the grid bars are at the same height or approximately at the same height, in the case of making the width direction of the first blade perpendicular to the width direction of the air outlet for horizontal air outlet (for example, during refrigeration operation), the influence on the exhaust airflow can be minimized.

[0015] Further, in the panel for air handling equipment, the number of grid bars can be equal to or less than the number of first blades. For example, the grid bars are arranged one-to-one corresponding to the first blades, so that the visual effect of the appearance of the panel can be maximally ensured. Alternatively, the grid bars are arranged corresponding to the first blades at intervals, so that the cost can be saved and the exhaust of the airflow is more conducive.

[0016] Further, in the panel for air handling equipment, preferably, the first shaft part is located at the middle part of the first blade in the flow path of the airflow flowing through the air outlet. For example, if the width of the first blade is L, and the distance between the first shaft part and the end part of the first blade is L1, the following relationship is satisfied: 1 / 3L≤L1≤2 / 3L.

[0017] According to the panel for air handling equipment, the first shaft part is located at the middle part of the first blade in the flow path of the airflow flowing through the air outlet, so that in the case of the air outlet being arranged in the horizontal direction, when the end part of the first blade on the downstream side of the airflow is lower than the end part on the upstream side of the airflow to blow air downward, the distance between the end part on the upstream side of the airflow of the uppermost first blade and the upper side inner wall surface of the air duct (which is provided with the first blade and the second blade, and the end part on the downstream side of the airflow constitutes the air outlet) is the smallest, which helps to avoid the airflow from leaking out of the gap between the end part on the upstream side of the airflow of the uppermost first blade and the upper side inner wall surface of the air duct, and on the other hand, helps to ensure the guiding effect on the airflow blown out of the air outlet.

[0018] Further, in the panel for air handling equipment of the utility model, preferably the panel frame has a side wall enclosing the air outlet, the side wall includes a first side wall and a second side wall opposite in the width direction of the air outlet, the first blade closest to one of the first side wall and the second side wall has a minimum distance from the one during rotation less than or equal to a first threshold value (that is, during operation or air supply, the minimum distance between the first blade and the first side wall or the second side wall when the first blade rotates to the limit position is less than or equal to the first threshold value).

[0019] Here, the limit position of the first blade can be the maximum air outlet angle of the first blade set on the control device such as a remote controller, a mobile phone terminal, etc. (as the air outlet angle, it can be defined as the angle between the first blade and the horizontal plane). Specifically, for example: when heating, the air direction is set to the first blade tilting downward, the angle between the first blade in the limit position and the horizontal plane is ≥ 50° and ≤ 70°, preferably 60°; when cooling, it is opposite, tilting toward the ceiling, that is, upward, the angle between the first blade in the limit position and the horizontal plane is ≥ 50° and ≤ 70°, preferably 55°, 60°.

[0020] On the other hand, in the automatic swing air mode, when the first blade is parallel to the horizontal plane, it is 0°, and the swing range of the first blade is, for example, between 0° and 70°, preferably between 0° and 60°, or between 0° and 55°.

[0021] According to the panel for air handling equipment of the utility model, when air is blown at the maximum angle, the end of the first blade closest to one of the first side wall and the second side wall is separated from the one of the first side wall and the second side wall by a gap, so that when the end of the first blade on the downstream side of the airflow is lower than the end on the upstream side of the airflow to blow air downward in the case where the air outlet is arranged in the horizontal direction, the airflow can be effectively prevented from leaking from the gap between the end on the upstream side of the airflow of the uppermost first blade and the upper inner wall surface of the air duct, and on the other hand, the guiding effect on the airflow blown out of the air outlet can be ensured.

[0022] Further, in the panel for air handling equipment of the utility model, preferably the panel frame has a side wall enclosing the air outlet, the side wall includes a first side wall and a second side wall opposite in the width direction of the air outlet, the first side wall and the second side wall are flush with the outer side surface of the grid strip, or the outer side surface of the first side wall and the second side wall protrudes outward more than the outer side surface of the grid strip, or the outer side surface of the grid strip protrudes outward more than the outer side surface of the first side wall and the second side wall.

[0023] Here, the so-called "outer side surface" refers to a surface on the downstream side of the airflow. In the case where the outer side surface is in an uneven shape such as an arc shape, the positional relationship between the outer side surfaces of the first and second side walls and the outer side surface of the grid bar is determined based on the edge line of the outermost end (the end portion closest to the downstream side of the airflow) of the outer side surface.

[0024] According to the panel for an air handling equipment of the present application, when the outer side surfaces of the first and second side walls are flush with the outer side surface of the grid bar, miniaturization can be achieved, the structure is more compact, and the appearance can be ensured to be consistent in appearance; when the outer side surfaces of the first and second side walls protrude more outward than the outer side surface of the grid bar, the grid bar is less likely to block the airflow; and when the outer side surface of the grid bar protrudes more outward than the outer side surfaces of the first and second side walls, the guiding effect of the airflow blown out from the air outlet can be facilitated.

[0025] In addition, in the panel for an air handling equipment of the present application, preferably, the panel frame has a side wall surrounding the air outlet, the side wall includes first and second side walls opposite in the width direction of the air outlet, and the first vane does not protrude beyond the outer side surfaces of the first and second side walls.

[0026] Here, as above, the so-called "outer side surface" refers to a surface on the downstream side of the airflow. In the case where the outer side surface is in an uneven shape such as an arc shape, the positional relationship between the outer side surfaces of the first and second side walls and the first vane is determined based on the edge line of the outermost end (the end portion closest to the downstream side of the airflow) of the outer side surface.

[0027] According to the panel for an air handling equipment of the present application, the first vane does not protrude beyond the outer side surfaces of the first and second side walls, that is, the first vane is hidden inside the side wall surrounding the air outlet, which helps to ensure the appearance.

[0028] In addition, in the panel for an air handling equipment of the present application, preferably, if the position of the first vane when the width direction of the first vane is perpendicular to the width direction of the air outlet is a reference position, the first vane is rotated relative to the reference position by an angle greater than or equal to 40° in the closed state.

[0029] According to the panel for an air handling equipment of the present application, the first vane is rotated relative to the reference position by an angle greater than or equal to 40° in the closed state, so that in the case where the air outlet is arranged in a horizontal direction, the internal components are less likely to be visible when the first vane is in the closed state, the appearance can be ensured, and the dustproof effect can be improved.

[0030] In addition, in the panel for air treatment equipment, preferably, the panel frame has an air duct for the first blade and the second blade, an end of the air duct on a flow path of the airflow forms the air outlet, edges of both sides of the first blade in a length direction of the air outlet are provided with a cutout at an end close to an inner wall surface of the air duct, or at least one partition plate is arranged in the air outlet, the first blade comprises multiple segments separated by the partition plate in the length direction, edges of both sides of each segment in the length direction of the air outlet are provided with a cutout at an end close to at least one of the inner wall surface of the air duct and the partition plate.

[0032] In addition, in the panel for air treatment equipment, preferably, the panel frame has a side wall spliced to form the air outlet, and at least one partition plate arranged in the air outlet.

[0033] According to the panel for air treatment equipment, the side wall can be spliced to form the air outlet according to different sizes of the air outlet, which helps to inhibit manufacturing cost, on the other hand, the partition plate can be used to support the grid strip, inhibit the bending deformation of the grid strip after long-term use, and the first shaft part can also be supported by the partition plate.

[0067] (utility model effect)

[0068] According to the utility model, the panel frame has at least one fixed grid strip at the air port, the grid strip is arranged along the length direction of the air port, the first blade is upstream of the grid strip in the airflow direction (i.e. close to the inner side of the panel frame), the panel frame further includes at least one second blade, the second blade is arranged along the width direction of the air port, and is upstream of the first blade in the airflow direction (i.e. close to the inner side of the panel frame), therefore, even if the first blade needs to be rotated, the rotation of the first blade will not be easily perceived due to the shielding of the grid strip, the change of the appearance at the air port of the air treatment equipment panel is inhibited, thereby, the airflow direction can be changed in multiple directions by the first blade and the second blade, at the same time, it is easy to ensure that the appearance of the air treatment equipment panel is basically unchanged, that is, the rotation of the internal blade does not affect the overall aesthetics of the external grid in vision, the indoor decoration consistency can be maintained and airflow guiding can be performed, and aesthetics and function are considered.

[0069] Further, according to the utility model, the air treatment equipment panel includes a driving part, the driving part is arranged on the panel frame, and drives the first blade to rotate around the first shaft part, the air port functions as an air outlet, and on the flow path of the airflow flowing through the air port, the first shaft part is located at the downstream side end of the first blade, and / or, the air port functions as an air inlet, and on the flow path of the airflow flowing through the air port, the first shaft part is located at the upstream side end of the first blade, therefore, the airflow can be conveniently guided in different directions by the first blade towards the outside or inside of the air treatment equipment panel, and unlike the case that the first shaft part is arranged at the middle part of the first blade, one end of the first blade (i.e. the end where the first shaft part is located) can be made closer to the downstream side or the upstream side on the flow path of the airflow within the rotation range of the first blade, therefore, it is helpful to guide the airflow blown out from the air treatment equipment panel to the indoor more remotely in multiple directions by the first blade, or to guide the airflow flowing towards the inside of the air treatment equipment panel more early in multiple directions by the first blade; and the swing angle of the first blade can be made larger, and the airflow guiding angle can be made larger.

[0070] Further, according to the present application, when the air opening functions as an air outlet, the first shaft portion is located at the downstream side end portion of the first blade on the flow path of the airflow passing through the air opening, and / or when the air opening functions as an air inlet, the first shaft portion is located at the upstream side end portion of the first blade on the flow path of the airflow passing through the air opening, thus, unlike the case where the first shaft portion is located at the upstream side end portion of the first blade when the air opening functions as an air outlet (or the first shaft portion is located at the downstream side end portion of the first blade when the air opening functions as an air inlet), the noise generated by the shaking of the first blade can be suppressed; that is, in the case where the first shaft portion is located at the upstream side end portion of the first blade when the air opening functions as an air outlet (or the first shaft portion is located at the downstream side end portion of the first blade when the air opening functions as an air inlet), the downstream side end portion (or the upstream side end portion) of the first blade is not fixed, and the first blade is easily shaken by the airflow passing through the air opening during the operation of the air handling unit, thus generating noise, in contrast, according to the present application, the downstream side end portion of the first blade when the air opening functions as an air outlet (or the upstream side end portion of the first blade when the air opening functions as an air inlet) is made firm by the shaft portion located close to the indoor side, thus the shaking of the first blade by the airflow passing through the air opening during the operation of the air handling unit can be suppressed, the noise can be reduced, and the comfort of the indoor environment of the user can be ensured.

[0131] Below, the panel for air handling device of the embodiment of the utility model is explained in the case of using as an air outlet panel, combined with the drawings. And, as an air handling device, taking a ducted type air conditioner as an example to explain.

[0132] Here, for the convenience of explanation, three directions mutually orthogonal are set as X direction, Y direction and Z direction, and one side of X direction is set as X1, the other side of X direction is set as X2, one side of Y direction is set as Y1, the other side of Y direction is set as Y2, one side of Z direction is set as Z1, and the other side of Z direction is set as Z2.

[0133] <Embodiment 1>

[0134] (Overall structure of the panel for air handling device)

[0135] As shown in Figures 1 to 4 , the air handling device panel 1 includes a panel frame 10 provided with a register FK, and at least one first blade 20 (also generally referred to as a horizontal blade when the air handling device panel 1 is arranged with the register FK facing in a horizontal direction) extending in a length direction of the register FK (in the illustrated example, coinciding with the X direction), provided with a first shaft portion 21 extending in the length direction of the register FK, and rotatably supported to the panel frame 10 via the first shaft portion 21.

[0136] Here, referring to the solid arrow in Figure 3 , the register FK functions as an air outlet for air flow to be blown out, and in a flow path of the air flow passing through the register FK, the first shaft portion 21 is located at an end portion of the first blade 20 on a downstream side (in the illustrated example, the Y1 direction side) thereof. Also, the air handling device panel 1 further includes a drive portion 30 provided to the panel frame 10, and driving the first blade 20 to rotate about the first shaft portion 21.

[0137] Further, as shown in Figures 1 to 4 , the air handling device panel 1 further includes at least one second blade 40 (also generally referred to as a vertical blade when the air handling device panel 1 is arranged with the register FK facing in a horizontal direction) extending in a width direction of the register FK (in the illustrated example, coinciding with the Z direction), and located more upstream in the air flow direction than the first blade 20, that is, the second blade 40 is located on a side opposite to the register FK (in the illustrated example, the Y2 direction side) with respect to the first blade 20. The second blade 40 is provided with a second shaft portion extending in the width direction of the register FK, and rotatably provided to the panel frame 10 via the second shaft portion. Also, the drive portion 30 further drives the second blade 40 to rotate.

[0138] Further, although not shown, the air handling device panel 1 forms an air handling system in connection with a ducted fan coil unit via a duct or directly, and the operation of the first blade 20 and the second blade 40 is controlled, for example, by a control portion provided to the ducted fan coil unit or the like. Also, the ducted fan coil unit is connected to an outdoor unit via a refrigerant communication pipe, thereby forming a refrigerant circuit to perform, for example, cooling or heating operation. Also, in a case where the air handling device panel 1 functions as an air outlet panel, during the cooling operation (or the heating operation), the ducted fan coil unit sends the air flow cooled (or heated) by the refrigerant to the air handling device panel 1 via the duct, and blows out to, for example, the inside of a room via the register FK (in a case where the air handling device panel 1 functions as an air inlet panel, the air flow enters the inside of the ducted fan coil unit via the register FK).

[0139] (Structure of Panel Frame)

[0140] As shown in Figure 3 and Figure 4 , the panel frame 10 has a duct FD in which the first blade 20 and the second blade 40 are disposed, and an end portion of the duct FD on the flow path of the airflow (an end portion on the downstream side, i.e., the Y1 direction side in the illustrated example) constitutes an air port FK.

[0141] Here, as shown in Figure 3 and Figure 4 , the panel frame 10 has a first disposition region Q1 in which the first blade 20 is disposed, and a second disposition region Q2 in which the second blade 40 is disposed, the first disposition region Q1 being formed in a flared shape in which the dimension in the length direction of the air port FK is larger than the second disposition region Q2. Specifically, the panel frame 10 has a cylindrical portion 11 that constitutes the duct FD, the cylindrical portion 11 constituting the air port FK at one end (an end on the downstream side, i.e., the Y1 direction side in the illustrated example) on the flow path of the airflow. Further, the first disposition region Q1 and the second disposition region Q2 are disposed inside the cylindrical portion 11. More specifically, the cylindrical portion 11 includes an outer cylinder that constitutes first and second side walls of the duct FD on both sides in the width direction of the air port FK, and a duct-forming wall that constitutes third and fourth side walls of the duct FD on both sides in the length direction of the air port FK (i.e., the panel frame 10 has side walls that surround the air port FK, the side walls including the first, second, third, and fourth side walls), and the first disposition region Q1 and the second disposition region Q2 are disposed inside the duct-forming wall. Further, on the flow path of the airflow, the first disposition region Q1 is located on the downstream side of the second disposition region Q2, the air port FK is disposed at the end portion on the downstream side, and the dimension in the length direction of the air port FK (in the illustrated example, coinciding with the X direction) is larger the further on the downstream side (in the illustrated example, as viewed in the Z direction, the first disposition region Q1 is in a trapezoidal shape, and the bottom angle Θ of the air port FK side is, for example, 45-60 degrees).

[0142] Further, as shown in Figure 1 , Figure 2 and Figure 4As shown, the panel frame 10 has at least one (three in the illustrated example, but not limited thereto, arranged at equal intervals in the Z direction) fixed grating bar 12 (i.e., the grating bar 12 does not rotate when the air handling device is in operation) at the air port FK, which extends in the length direction of the air port FK. Specifically, the grating bar 12 is fixed at both ends in the length direction of the air port FK to the cylindrical portion 11 (in the illustrated example, to the opposite wall portions of the cylindrical portion 11 in the X direction), and the cross section of the grating bar 12 perpendicular to the length direction of the air port FK is substantially rectangular (for example, the corners are chamfered). The size of the grating bar 12 in the width direction of the air port FK (in the illustrated example, coincides with the Z direction) is greater than or equal to the maximum thickness of the portion of the first blade 20 other than the first shaft portion 21 (including the following rib portion 221, in the illustrated example, preferably also greater than or equal to the thickness of the first shaft portion 21).

[0143] (Structure of first blade)

[0144] As described above, the first blade 20 has the first shaft portion 21.

[0145] Here, as shown in Figure 1 and Figure 4 , the first blade 20 extends in the length direction of the air port FK, and is housed in the cylindrical portion 11 of the panel frame 10 with the first shaft portion 21 positioned near the air port FK.

[0146] Further, as shown in Figure 4 , the first blade 20 is provided corresponding to at least part of the grating bar 12 (in the illustrated example, three are provided one-to-one corresponding to the grating bars 12), and the first shaft portion 21 is aligned with the position of the grating bar 12 at a position closer to the inner side (in the illustrated example, the Y2 direction side) of the panel frame 10 than the grating bar 12. Also, by providing the first blade 20, the air port FK can be divided into a plurality of linear sub-air ports in the width direction thereof.

[0147] Further, as shown in Figure 1 , Figure 3 and Figure 5As shown, the first blade 20 also has a long, plate-shaped first blade body 22. A first shaft portion 21 is provided at both ends along the length of the first blade body 22, and the first blade body 22 is rotatably supported on the panel frame 10 (in the illustrated example, this is the spaced-apart wall portion of the cylindrical portion 11, i.e., the duct forming wall) via the first shaft portion 21. Furthermore, ribs 221 are provided on the first blade body 22, and these ribs 221 are provided on one side of the surface of the first blade body 22 in the thickness direction (but are not limited to this; they may also be provided on the other side or both sides of the surface in the thickness direction). The ribs 221 extend in a direction intersecting the extending direction of the first shaft portion 21, and multiple ribs are provided at intervals along the extending direction of the first shaft portion 21. Moreover, the first blade body 22 is formed such that the thickness gradually decreases at its front end (the end opposite to the first shaft portion 21).

[0148] Furthermore, it is preferable that the first blade 20 does not extend beyond the outer surfaces of the first and second sidewalls of the cylinder 11 (in the illustrated example, the surface on the Y1 direction side).

[0149] Furthermore, as described above, the panel frame 10 has sidewalls surrounding the air vent FK. These sidewalls include a first sidewall and a second sidewall opposite each other in the width direction of the air vent FK. The first blade 20, closest to one of the first or second sidewalls, has a minimum distance (in the illustrated example, the angle at which the first blade 20 forms the largest angle with the horizontal position when rotating upwards or downwards) less than or equal to a first threshold during rotation (either automatic or manual switching). This first threshold is, for example, 10 mm. By ensuring that this minimum distance is less than or equal to 10 mm, airflow leakage from the gap between the first blade 20 and the first (or second) sidewall is effectively prevented, and the airflow guidance effect is ensured.

[0150] Furthermore, the first blade 20 can automatically adjust its angle when closed. Specifically, if the width direction of the first blade 20 is perpendicular to the width direction of the air outlet FK (refer to...) Figure 4 If the position of the first blade 20 is taken as the reference position, then the angle of rotation of the first blade 20 relative to the reference position in the closed state is greater than or equal to 40° (e.g., 40° to 90°, or 40° to 75°). Therefore, when the first blade is in the closed state, it is easy to ensure that the internal components are not visible, thus improving the dustproof effect while ensuring aesthetics.

[0151] In addition, the first blade 20 can control its direction according to different operational needs, forming an automatic oscillating blade.

[0152] (Structure of the second blade)

[0153] As described above, the second blade 40 has a second shaft portion.

[0154] Here, as shown in Figures 1 to 4 Fig. 2, the second blade 40 extends in the width direction of the air port FK.

[0155] Further, as shown in Figure 4 Fig. 2, the second blade 40 also has a long strip plate-shaped second blade body 42. Second shaft portions are provided at both ends in the length direction of the second blade body 42, and the second blade body 42 is rotatably supported to the panel frame 10 via the second shaft portions. Also, a plurality of second blades 40 (the specific number can be appropriately set as needed) are arranged in the length direction of the air port FK, and are rotatably provided to the panel frame 10 (in the example shown, to the wall portions of the cylindrical portion 11 that are opposite and spaced apart in the Y direction) in a manner that can be switched between a first position that opens the air passage FD and a second position that closes the air passage FD via the second shaft portions.

[0156] Further, it is preferable that the minimum interval between the second blade 40 and the first blade 20, i.e., the interval between the end portion on the Y2 direction side of the first blade 20 and the end portion on the Yl direction side of the second blade 40 in the state shown in Figure 4 Fig. 2 (at this time, the thickness direction of the first blade 20 coincides with the Z direction, and the thickness direction of the second blade 40 coincides with the X direction) be 2 mm or more.

[0157] Further, the second blade 40 can control the direction according to different operation requirements, forming an automatic swing leaf.

[0158] (Structure of the drive portion)

[0159] As shown in Figure 1 and Figure 2 Fig. 3, the drive portion 30 includes a first blade drive portion 31 that drives the first blade 20.

[0160] Here, as shown in Figures 1 to 3 Fig. 3, a plurality of first blade drive portions 31 are provided in correspondence with the first blade 20. Specifically, the first blade drive portion 31 is a motor provided outside the cylindrical portion 11 of the panel frame 10 on the one end side in the length direction of the first blade 20.

[0161] Further, as shown in Figures 1 to 3As shown, the drive section 30 also includes a second vane drive section 32 that drives the second vanes 40. Specifically, the second vane drive section 32 is a motor provided outside the cylindrical section 11 of the panel frame 10 on the one end side in the length direction of the first vanes 20. Also, the second vane drive section 32 drives the second vanes 40 to rotate via a link 50. The link 50 is preferably provided outside the air duct FD (for example, extending in the X direction on the Z2 direction side of the cylindrical section 11, and the Z2 direction side of the second shaft section of the second vanes 40 penetrates the wall section on the Z2 direction side of the cylindrical section 11 to be rotationally connected to the link 50).

[0162] (Example of operation of the panel for an air handling device)

[0163] Here, it is assumed that the air outlet FK faces the horizontal direction, and the panel for an air handling device functions as an air outlet panel.

[0164] During heating operation, as shown in FIG. 6, the first vanes 20 are rotated so that the leading ends thereof approach the wall section on the upper side (Zl direction side in the illustrated example) of the cylindrical section of the panel frame 10, and the leading end of the uppermost first vane 20 abuts against the wall section on the upper side. Thus, unlike the case shown in FIG. 5, the hot air can be prevented from escaping through the gap on the upper side of the uppermost first vane, and the problem that part of the airflow cannot be guided in the prescribed direction by the first vanes can be avoided. Figure 6A Figure 6B During cooling operation, as shown in FIG. 7, the first vanes 20 are rotated so that the leading ends thereof approach the wall section on the lower side (Z2 direction side in the illustrated example) of the cylindrical section of the panel frame 10, and the leading end of the lowermost first vane 20 abuts against the wall section on the lower side. Thus, unlike the case shown in FIG. 8, the cold air can be prevented from escaping through the gap on the lower side of the lowermost first vane, and the problem that part of the airflow cannot be guided in the prescribed direction by the first vanes can be avoided.

[0165] On the other hand, during cooling operation, as shown in FIG. 7, the first vanes 20 are rotated so that the leading ends thereof approach the wall section on the lower side (Z2 direction side in the illustrated example) of the cylindrical section of the panel frame 10, and the leading end of the lowermost first vane 20 abuts against the wall section on the lower side. Thus, unlike the case shown in FIG. 8, the cold air can be prevented from escaping through the gap on the lower side of the lowermost first vane, and the problem that part of the airflow cannot be guided in the prescribed direction by the first vanes can be avoided.

[0166] (Main effects of the present embodiment)

[0167] ​​​According to the panel 1 for an air handling device of the present embodiment, the panel frame 10 has at least one fixed grid bar 12 at the air outlet FK, the grid bar 12 is arranged along the length direction of the air outlet FK, the first blade 20 is located at a position closer to the inner side of the panel frame 10 than the grid bar 12, the panel frame 10 further comprises at least one second blade 40, the second blade 40 is arranged along the width direction of the air outlet FK and is located at a position closer to the inner side of the panel frame 10 than the first blade 20, therefore, even if the first blade 20 needs to be rotated, the rotation of the first blade 20 will not be easily noticed due to the shielding of the grid bar 12, the change of the appearance at the air outlet FK of the panel 1 for an air handling device is inhibited, thereby, the flow direction of the air flow can be changed in multiple directions by the first blade 20 and the second blade 40, at the same time, it is easy to ensure that the appearance of the panel 1 for an air handling device is basically unchanged, that is, the rotation of the internal blade does not affect the overall beauty of the external grid in vision, the indoor decoration can be kept consistent and the air flow guiding can be performed, the beauty and the function are taken into account. In short, the panel 1 for an air handling device can hide the automatic swing blade in the grid, and realize the beauty and the air conditioning effect at the same time.

[0168] According to the panel 1 for an air handling device of the present embodiment, the driving part 30 is arranged on the panel frame 10 and drives the first blade 20 to rotate around the first shaft part 21, the first shaft part 21 is located at the downstream side end part of the first blade 20 on the flow path of the air flow flowing through the air outlet FK serving as the air outlet, therefore, the air flow can be conveniently guided in different directions outside the panel 1 for an air handling device by the first blade 20, and unlike the case that the first shaft part 21 is arranged at the middle part of the first blade 20 or the like, one end part of the first blade 20 (i.e. the end part where the first shaft part 21 is located) can be made closer to the downstream side on the flow path of the air flow within the rotation range of the first blade 20, therefore, it is helpful to guide the air flow blown out from the panel 1 for an air handling device to the indoor space farther in multiple directions by the first blade 20; and the swing angle of the first blade 20 can be made larger, and the air flow guiding angle can be made larger.

[0169] Furthermore, according to the air handling unit panel 1 of this embodiment, in the flow path of the airflow passing through the air outlet FK which functions as an air outlet, the first shaft portion 21 is located at the downstream end of the first blade 20. Therefore, unlike the case where the first shaft portion 21 is set at the upstream end of the first blade 20 when the air outlet FK functions as an air outlet, the noise generated by the vibration of the first blade 20 can be suppressed. In other words, when the first shaft portion 21 is set at the upstream end of the first blade 20 when the air outlet FK functions as an air outlet, the downstream end of the first blade 20 is not fixed, which easily leads to the vibration of the first blade 20 and generates noise. In contrast, according to the air handling unit panel 1 of this embodiment, when the air outlet FK functions as an air outlet, the downstream end of the first blade 20 becomes sturdy because the shaft portion is provided near the indoor side, which can suppress the vibration of the first blade 20 when the airflow passes through it during the operation of the duct unit, reduce noise, and ensure the comfort of the user's indoor environment.

[0170] <Implementation Method 2>

[0171] The air handling unit panel of Embodiment 2 is basically the same as the air handling unit panel of Embodiment 1. The air handling unit panel of Embodiment 2 will be described below focusing on the differences from the air handling unit panel of Embodiment 1.

[0172] In this embodiment, such as Figures 8 to 11B As shown, similar to Embodiment 1, the air handling unit panel 1 includes a panel frame 10, a first blade 20, a second blade 40, and a drive unit 30. The panel frame 10 has an air vent FK. The first blade 20 is disposed along the length direction of the air vent FK and has a first shaft portion 21 extending along the length direction of the air vent FK, and is rotatably supported on the panel frame 10 via the first shaft portion 21. The second blade 40 is disposed along the width direction of the air vent FK and is located closer to the inside of the panel frame 10 than the first blade 20. The drive unit 30 drives the first blade 20 to rotate around the first shaft portion 21 and drives the second blade 40 to rotate around a second shaft portion.

[0173] However, in the present embodiment, unlike in Embodiment 1, the panel frame 10 has side walls that join to form the air port FK, and a partition plate 14 provided in the middle of the air port FK. Specifically, the cylindrical portion 11 of the panel frame 10 includes a first side wall 111, a second side wall 112, a third side wall 113, and a fourth side wall 114 that join to form the air port FK, the first side wall 111 and the second side wall 112 oppose each other in the width direction of the air port FK, the third side wall 113 and the fourth side wall 114 oppose each other in the length direction of the air port FK, and connect both ends of the first side wall 111 and the second side wall 112 in the length direction of the air port FK. The third side wall 113 and the fourth side wall 114 each include a plate-shaped portion 1131, 1141 whose thickness direction coincides with the length direction of the air port FK, and a protruding frame portion 1132, 1142 that protrudes from the plate-shaped portion 1131, 1141 toward the side away from the air port FK, and the outer side surface (the surface on the Y1 direction side) is assembled with a decorative cover 13 that covers the drive portion 30, and is provided with a protruding rib that aligns with the grille strip 12. A clamping portion KJ for clamping and fixing the grille strip 12 is provided at a portion of the third side wall 113 and the fourth side wall 114 that is outside the air duct FD. The partition plate 14 is provided with at least one (three in the illustrated example) that connects to the first side wall 111 and the second side wall 112 at both ends in the width direction of the air port FK, and is provided so that the thickness direction coincides with the length direction of the air port FK, thereby partitioning the air port FK into a plurality of sub-air ports in the length direction of the air port FK. The partition plate 14 also supports the first shaft portion 21 of the first blade 20 and the middle of the length direction of the grille strip 12. The partition plate 14 has a through hole through which the first shaft portion 21 of the first blade 20 passes, and has a clamping portion KJ (provided at the edge of the partition plate 14 on the Y1 direction side in the illustrated example, and on the outside of the air port FK from the through hole of the partition plate 14 through which the first shaft portion 21 passes) for clamping and fixing the grille strip 12.

[0174] Further, in the present embodiment, unlike in Embodiment 1, as shown in Figure 9 the first blade 20 is not a single piece, but is formed of a plurality of pieces connected to each other by shaft portions.

[0175] Further, in the present embodiment, unlike in Embodiment 1, as shown in Figure 11A and Figure 11B a groove that extends in the length direction of the first blade 20 is provided instead of the rib portion 221 on the first blade body 22 of the first blade 20. Further, in the present embodiment, unlike in Embodiment 1, as shown in Figure 9As shown in FIG. 11, unlike the embodiment 1, the first shaft portion 21 is located at the middle of the first blade 20 on the flow path of the airflow flowing through the air port FK. For example, if the width of the first blade 20 is L, and the distance between the first shaft portion 21 and the end of the first blade 20 is L1, the following relationship is satisfied: 1 / 3L≤L1≤2 / 3L.

[0176] In addition, in the present embodiment, as shown in FIG. 10, Figure 9 As shown in FIG. 11, unlike the embodiment 1, the edges of the first blade 20 on both sides in the length direction of the air port FK are provided with cutouts 222 at the end close to the inner wall surface of the air duct FD. At the cutouts 222, the minimum distance between the first blade 20 and the inner wall surface of the air duct FD during rotation is preferably greater than 10 mm and less than 50 mm, thereby being able to expand the air inlet amount. Moreover, the cutouts 222 include: a first cutout 2221 formed on the edge of the upstream side of the airflow of the first blade 20; and a second cutout 2222 formed on the edge of the downstream side of the airflow of the first blade 20. The distance L1 between the first cutout 2221 and the inner wall surface of the third side wall 113, the fourth side wall 114, or the partition plate 14 is greater than the distance L2 between the second cutout 2222 and the inner wall surface of the third side wall 113, the fourth side wall 114, or the partition plate 14. Thereby, the air inlet amount and the air outlet amount can be expanded. Of course, the cutouts 222 can also be formed only on the edge of the upstream side of the airflow of the first blade 20.

[0177] In addition, in the present embodiment, as shown in FIG. 10, Figure 9 As shown in FIG. 11, unlike the embodiment 1, the second blade 40 is not directly provided on the panel frame 10, but is installed in a form of modularization after grouping.

[0178] In addition, in the present embodiment, as shown in FIG. 10, Figure 9 As shown in FIG. 11, unlike the embodiment 1, the connecting rod 50 is provided in the air port FK.

[0179] (Main effects of the present embodiment)

[0180] According to the panel 1 for air handling equipment of the present embodiment, the same effects as the above-mentioned embodiment 1 can be achieved.

[0181] In addition, according to the panel 1 for air handling equipment of the present embodiment, the side walls of the panel frame 10 can be spliced to form the air port FK according to different sizes of the air port FK, which helps to suppress the manufacturing cost. Moreover, the air port FK formed by splicing can also cope with different sizes of air handling equipment, and through splicing expansion, different installation scenes can be flexibly coped with.

[0182] Further, according to the panel 1 for an air handling device of the present embodiment, the grid bars 12 are supported by the partition plates 14, and bending deformation of the grid bars 12 after long-term use is suppressed. In addition, the first shaft portions 21 are supported by the partition plates 14.

[0183] Further, according to the panel 1 for an air handling device of the present embodiment, the second vanes 40 and the links 50 are provided in groups, and the panel 1 can be easily spliced according to the size of the air outlet FK.

[0184] Further, according to the panel 1 for an air handling device of the present embodiment, the decorative covers 13 on both sides of the air outlet FK are used to create the effect of visually extending the grid bars 12, and thus, when the site is decorated, it is easy to ensure that the suspended ceiling maintains a uniform appearance in the entire length direction (maintains the continuity of the decoration) according to the environment of the site, and the aesthetic appearance is improved.

[0185] Further, according to the panel 1 for an air handling device of the present embodiment, as shown in Figure 12A Even if the first vane 20 is rotated so that the front end thereof is close to the second side wall 112 below the panel frame 10, it is different from the case where the first shaft portion is located in the middle of the first vane 20 as shown in Figure 12B , the problem that the airflow escapes through the gap on the upper side of the uppermost first vane 20 and part of the airflow cannot be guided by the first vane 20 toward the prescribed direction is suppressed.

[0186] The utility model has been described above in conjunction with the drawings, and obviously the specific implementation of the utility model is not limited by the above-mentioned embodiments.

[0187] For example, in the above-mentioned embodiment 1, the panel 1 for an air handling device is described by taking the case of being used as an air outlet panel as an example, but it is not limited thereto, and the panel 1 for an air handling device can also be used as an air inlet panel. At this time, referring to the dotted arrow in Figure 3 , the air outlet FK functions as an air inlet, and the first shaft portion 21 is located at the upstream side end portion of the first vane 20 on the flow path of the airflow flowing through the air outlet FK.

[0188] In the above case, the first blade 20 can be used to conveniently direct the air flow in different directions toward the inside of the air handling device panel, and, unlike the case where the first shaft portion 21 is arranged at the middle portion of the first blade 20, etc., the end portion of the first blade 20 (i.e., the end portion where the first shaft portion is arranged) can be made closer to the upstream side on the flow path of the air flow within the rotation range of the first blade 20, thus helping to direct the air flow flowing toward the inside of the air handling device panel earlier in multiple directions by using the first blade. Also, unlike the case where the first shaft portion 21 is arranged at the downstream end portion of the first blade 20 when the air outlet FK functions as an air inlet, the noise generated by the first blade 20 shaking when the air flow flows during operation of the air handling device can be suppressed.

[0189] Also, in the above case, a large air flow area can be ensured at the position close to the outside of the user, the air flow noise is less, and the area compression until entering the inside of the panel can improve the wind speed of the air flow entering the air handling device, i.e., breaking the limitation of the size of the air inlet of the air handling device, expanding the part of the panel leading to the air flow, enlarging the suction inlet, increasing the air inlet area, improving the performance, and being conducive to reducing the noise of the suction inlet.

[0190] Similarly, in the above embodiment 2, the air handling device panel 1 can also be used as an air inlet panel.

[0191] In addition, in the above embodiment, the air handling device is a ducted type air conditioner, but it can also be a total heat exchanger, a humidification device, a dehumidification device, a fresh air machine, etc.

[0192] In addition, in the above embodiment, when decorating, the air handling device panel 1 can be arranged such that the length direction (X direction in the figure) of the air outlet FK is consistent with the horizontal direction, or such that the length direction of the air outlet FK is consistent with the vertical direction.

[0193] In addition, in the above embodiment, when decorating, the air handling device panel 1 can also be arranged such that the air outlet FK faces downward, so that, in the case where the air outlet FK functions as an air outlet, by connecting the air handling device panel 1 on one side of the air handling device and connecting an air inlet panel having an air inlet facing downward on the other side of the air handling device, etc., a down-sending and down-returning scene can be realized, at this time, by rotating part of the first blades 20 toward one side and rotating the remaining first blades 20 toward the other side, the air can be swept toward both sides to avoid air flow short circuiting. Also, as Figure 21As shown, during decoration, two air handling equipment panels 1 can also be connected on the air handling equipment 3, whereby in the case of the air outlet FK serving as an air outlet, by rotating the first blade 20 on one air handling equipment panel 1 to one side and rotating the first blade 20 on the other air handling equipment panel 1 to the other side, air can also be swept to both sides, avoiding air flow short circuiting.

[0194] In addition, in the above embodiment, the outer side of the first and second side walls of the cylinder portion 11 (the surface on the Y1 direction side in the illustrated example) can be flush with the outer side of the grid bars 12, or the outer side of the first and second side walls of the cylinder portion 11 can protrude further outward than the outer side of the grid bars 12, or the outer side of the grid bars 12 can protrude further outward than the outer side of the first and second side walls of the cylinder portion 11.

[0195] In addition, in the above embodiment, as shown in Figs. 1 and 2, Figure 13A and Figure 13B As shown, one or more decorative grilles 2 (which can also be referred to as decorative panels or extension panels) can also be spliced on one or both sides of the air handling equipment panel 1 in the length direction of the air outlet FK to form a panel assembly. In particular, by providing left and right symmetrical decorative grilles 2, the panel length can be flexibly adjusted, and in on-site decoration, the ceiling can easily maintain a uniform appearance in the entire length direction (maintaining the continuity of the decoration) according to the on-site environment, improving the aesthetic appearance, and also achieving the effect of 3D air flow guiding of the air conditioner.

[0196] In the above case, the decorative grille 2 is preferably provided with at least one decorative grid bar extending in the length direction of the air outlet FK, which is connected in alignment with the grid bars 12 of the air handling equipment panel 1 (or the protruding ribs of the decorative cover 13), whereby the panel assembly can be flexibly spliced according to the installation environment, and can be visually integrated, improving the aesthetic appearance.

[0197] In the above case, during decoration, the panel assembly can be arranged such that the length direction of the air outlet FK is consistent with the horizontal direction, or the length direction of the air outlet FK is consistent with the vertical direction.

[0198] In the above case, as the decorative grille 2, the main body can be formed in an open structure, and during decoration, decorative grid bars of the same or different lengths can be spliced, flexibly arranged according to the installation environment, and the appearance is uniform, maintaining the aesthetic appearance, and during construction, sealing material can also be applied to the non-air outlet (non-air inlet) part (such as the back or the periphery) to prevent dust, insects, etc. from entering the ceiling.

[0199] In addition, in the above embodiment 1, as shown in Fig. 13, the connecting rod 50 can also be arranged to extend into the air duct FD.

[0200] Further, in the above-described embodiment 1, a plurality of link members 50 can be provided, for example, a plurality of second vanes 40 are divided into two groups in the length direction of the air outlet FK and are driven by one link member 50, respectively, whereby separate control can be performed, and air is blown toward or away from a person according to the detection result of an environmental detection element such as a person detection sensor.

[0202] Further, in the above-described embodiment, as shown in Figure 15 Further, in the above-described embodiment, as shown in

[0203] In the above-described case, when the air outlet FK functions as an air outlet, windless air supply can be achieved; on the other hand, when the air outlet FK functions as an air inlet, air can uniformly enter the air handling device through the hole H, and more precise performance adjustment can be achieved.

[0204] Further, in the above-described embodiment 1, the first vane 20 is housed in the cylindrical portion 11 of the panel frame 10 with the first shaft portion 21 located near the air outlet FK, but is not limited thereto, and according to the situation, the first shaft portion 21 can be provided outside the cylindrical portion 11 (for example, a protruding portion protruding in the Y1 direction is provided on the wall portion on both sides of the cylindrical portion 11 in the X direction, and the first shaft portion 21 is supported by the protruding portion).

[0210] Further, in the above embodiment 1, the cross section of the grating bar 12 perpendicular to the length direction of the air port FK is not limited to a substantially rectangular shape, but can be formed in another shape such as a circular shape, and a recess in which at least a part of the first shaft portion 21 is accommodated can be formed on the side of the grating bar 12 facing the first shaft portion 21 (for example, refer to Figure 16 ), so as to suppress the air flow from flowing through the gap between the grating bar 12 and the first shaft portion 21.

[0212] Further, in the above embodiment, as shown in Figure 18 and Figure 19 , a second vane cutout CQ can be provided on the air flow downstream side of the second vane 40. Thereby, the distance between the second vane 40 below and the first vane 20 is increased, the air blowing effect can be ensured and the noise can be reduced when blowing air downward in the heating mode, the air flow between the second vane 40 and the first vane 20 can be made to flow smoothly, the resistance is reduced, and the noise caused by turbulence is avoided.
