Description

Technical Field

[0001] This application relates to the field of humidity control technology, such as a flow guide component and a humidity control device for a humidity control apparatus. Background Technology

[0002] Most fresh air dehumidification equipment uses condensation dehumidification, which has a low COP (coefficient of performance, which is the ratio of equipment cooling capacity to power consumption). Furthermore, because liquid water is generated during the dehumidification process, it can lead to problems such as bacterial growth and component corrosion.

[0003] A humidity control device is disclosed in related technology. The device includes: a housing with a first humidity control chamber, a second humidity control chamber, and a bypass passage; a refrigerant circuit having a compressor and a first and a second adsorption heat exchanger respectively disposed in the first and second humidity control chambers, and capable of switching between a condenser and an evaporator; a flow path switching mechanism for switching the airflow path within the housing; and a control unit for controlling the refrigerant circuit and the flow path switching mechanism to perform first and second humidity control operations. The flow path switching mechanism includes eight air valves and two bypass ventilation valves. Switching the airflow path within the housing is achieved by opening or closing the eight air valves and the two bypass ventilation valves respectively.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The large number of air valves required to switch flow paths increases the complexity of the humidity control device. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a flow guide assembly and a humidity control device for a humidity control apparatus, thereby reducing the complexity of the humidity control apparatus.

[0008] In some embodiments, the airflow guiding assembly for the humidity control device includes: a housing with multiple air vents on opposite sides; a baffle disposed within the housing; and a guide plate rotatably disposed within the housing. The guide plate, together with the baffle and the multiple air vents, forms different airflow paths when rotated to different preset positions.

[0009] In some embodiments, the humidity control device includes a flow guide assembly for the humidity control device as described above.

[0010] The flow guiding component and humidity regulating device provided in this disclosure can achieve the following technical effects:

[0011] By using a rotatable baffle plate within the housing, different airflow paths can be formed in conjunction with baffles and multiple air vents when rotated to different preset positions, thus varying the airflow paths. This eliminates the need to control numerous air valves; different airflow paths can be switched simply by adjusting the baffle assembly to different preset positions. Consequently, when the baffle assembly is used in a humidity control device, it reduces the complexity of the device.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figures 1 to 4 As shown, this disclosure provides an airflow guiding assembly 1 for a humidification device 2. The airflow guiding assembly 1 includes a housing 10, a partition 20, and a guide plate 30. The housing 10 includes four side plates 11, which together form a hollow frame structure. The housing 10 has multiple air outlets 40. Specifically, the multiple air outlets 40 are located on opposite sides, i.e., on two opposite side plates 11. The partition 20 is disposed inside the housing 10 and connected to three of the side plates 11. The guide plate 30 is disposed inside the housing 10 and rotatably connected to the two side plates 11 with the air outlets 40.

[0039] The deflector 30 has multiple preset rotation positions. When the deflector 30 rotates to different preset positions, the deflector 30 can work together with the baffle 20 to form different spaces. These spaces can be connected to different air vents 40, thereby forming different flow paths for air circulation.

[0040] The airflow guiding component 1 for the humidity control device 2 provided in this embodiment of the present disclosure, through the airflow guiding plate 30 rotatably disposed within the housing 10, can form different flow paths together with the baffle 20 and multiple air vents 40 when rotated to different preset positions, thus changing the airflow path. In this way, there is no need to control a large number of air valves; different flow paths can be switched simply by adjusting the rotation of the airflow guiding component 1 to different preset positions. Therefore, when the airflow guiding component 1 is applied to the humidity control device 2, the complexity of the humidity control device 2 can be reduced.

[0041] Optionally, among the multiple air vents 40, the air vents 40 located on opposite sides correspond one-to-one, forming two sets of air vents. The two corresponding air vents 40 in the same set, as well as the two air vents 40 in different sets but located on the same side, are located at different heights. That is, the air vents 40 include four air vents.

[0042] Optionally, combined Figure 3 and Figure 4As shown, the air vent 40 includes: a first air vent 41, a second air vent 42, a third air vent 43, and a fourth air vent 44. The first air vent 41 and the second air vent 42 are located on opposite sides, i.e., they are respectively opened on two opposite side panels 11, forming a corresponding set of air vents. The third air vent 43 and the fourth air vent 44 are located on opposite sides, i.e., they are respectively opened on two opposite side panels 11, forming another corresponding set of air vents. The first air vent 41 and the third air vent 43 are located on the same side, and the second air vent 42 and the fourth air vent 44 are located on the same side, i.e., they are opened on the same side panel 11. Specifically, the first air vent 41 and the third air vent 43 are opened on the first side panel 111, and the second air vent 42 and the fourth air vent 44 are opened on the second side panel 112. Spatially, with the partition 20 as the dividing line, the first air vent 41 and the second air vent 42 are located below and above the partition 20, respectively, and the third air vent 43 and the fourth air vent 44 are located above and below the partition 20, respectively. Thus, the first air vent 41 and the second air vent 42, the first air vent 41 and the third air vent 43, the fourth air vent 44 and the third air vent 43, and the second air vent 42 and the fourth air vent 44 are staggered in height with the partition 20 as the dividing line.

[0043] Optionally, the air vent 40 is a perforated structure formed on the side panel 11.

[0044] Optionally, the air vent 40 is a notch formed by recessing from the edge of the side plate towards the center. In this case, when the air guide assembly 1 is installed inside the humidity control device 2, the top wall of the housing 60 of the humidity control device 2 fits against the starting position of the notch, thereby making the housing 60 and the notch together form a complete air vent 40.

[0045] Optionally, the housing 10 further includes a top plate and / or a bottom plate 12. The top and bottom of the frame structure formed by the four side plates 11 are connected to the top plate and the bottom plate 12 respectively. In this way, the top plate and / or the bottom plate 12 can reinforce the frame structure and make the housing 10 more stable as a whole.

[0046] Optionally, when the air vent 40 is the aforementioned notch, the top plate and / or bottom plate 12 are fitted to the starting position of the notch so as to form a complete air vent 40 together with the notch.

[0047] Optionally, the partition 20 includes two baffles 21. The two baffles 21 are horizontally disposed inside the housing 10, corresponding to the first air vent 41 and the second air vent 42, and the third air vent 43 and the fourth air vent 44 respectively, and are located between the corresponding two air vents 40, thereby separating the corresponding two air vents 40. The two baffles 21 have a first preset distance between them to form an installation space for mounting the guide plate 30.

[0048] Optionally, the three sides of the baffle 21 are respectively connected to the two opposite side plates (first side plate 111 and second side plate 112) where the air vent is located, and to the side plate located between the two opposite side plates (e.g., the side plate 21 is located on). Figure 1 The third side plate 113 or the fourth side plate 114 shown are connected.

[0049] Optionally, the lateral dimension (width) of the baffle 21 is smaller than the lateral dimension (width) of the two corresponding air vents, that is, the width of the baffle 21 does not exceed the edge side of the two corresponding air vents. For example, see Figure 2 The width of the right-side baffle 21 is smaller than the width of the first air vent 41 and smaller than the width of the second air vent 42; the width of the left-side baffle 21 is smaller than the width of the third air vent 43 and smaller than the width of the fourth air vent 44. In this way, the two air vents corresponding to the baffle 21 are exposed, preventing the baffle 21 from blocking the corresponding air vents, thereby making the airflow smoother.

[0050] Optionally, the two baffles 21 are located on the same plane. This is because the baffles 21 need to form a flow path together with the guide plate 30. When the two baffles 21 are located on the same plane, it is beneficial to control the rotation angle of the guide plate 30 and avoid angle overshoot or inadequate adjustment.

[0051] Optionally, the guide vane 30 is disposed between the two baffles 21. When the guide vane 30 rotates to a preset position, it can divide the interior of the housing 10 into two spaces with the two baffles 21. At the same time, the relative position of the two spaces also changes as the guide vane 30 rotates to different preset positions. In this way, when the guide vane 30 rotates to different preset positions, different air vents 40 can be connected, thereby forming different flow paths.

[0052] Optionally, when the guide vane 30 rotates to the first preset position, the guide vane 30 and the two baffles 21 together divide the interior of the housing 10 into two spaces in the lateral direction. Optionally, combined with Figure 1 and Figure 2 As shown, the first preset position is a vertical position, that is, the guide plate 30 and the baffle 21 are perpendicular to each other. Thus, the two spaces are in a left-right relative position. At this time, the two sides of the guide plate 30 have a second preset distance from the two baffles 21 respectively, so as to cooperate with the two baffles 21 and form flow spaces on both sides of the guide plate 30, thereby connecting the two corresponding air vents 40 of the same group and separating the air vents 40 of different groups. That is, the first air vent 41 and the second air vent 42 are connected, and the third air vent 43 and the fourth air vent 44 are connected. At this time, combined with... Figure 5As shown, the airflow guiding component 1 divides the air into two paths. One path flows into the lower part of the right space from the first air inlet 41, then flows upward through the flow space between the baffle 21 and the guide plate 30 corresponding to the first air inlet 40 to the upper part of the right space, and finally flows out through the second air inlet 42. The other path flows into the lower part of the left space from the fourth air inlet 44, then flows upward through the flow space between the baffle 21 and the guide plate 30 corresponding to the fourth air inlet 44 to the upper part of the left space, and finally flows out through the third air inlet 43. At this time, the air flows to the left and right of the guide plate 30, and the flow paths do not intersect. This is a parallel flow path, which can be called co-current flow.

[0053] Optionally, when the guide vane 30 rotates to the second preset position, the guide vane 30 and the two baffles 21 together divide the interior of the housing 10 into two vertically oriented spaces. Optionally, combined with Figure 6 As shown, the second preset position is a horizontal position, meaning the guide plate 30 and the two baffles 21 are on the same plane. Simultaneously, the two sides of the guide plate 30 are abutted and fitted against the two baffles 21. The second direction is longitudinal, thus the two spaces are in a vertically relative position. Since the guide plate 30 is horizontal, its two sides and the two baffles 21 form a separating surface, thereby separating the corresponding two air vents 40 of the same group, while connecting the air vents 40 of different groups. That is, the first air vent 41 is connected to the fourth air vent 44, and the second air vent 42 is connected to the third air vent 43. At this time, the airflow assembly 1 divides the air into two paths: one path flows in from the first air vent 41, then flows in the lower space, and finally flows out through the fourth air vent 44; the other path flows in from the second air vent 42, then flows in the upper space, and finally flows out through the third air vent 43. At this time, the airflow paths of the airflow assembly 1 intersect in space, which can be called crossflow.

[0054] Optionally, combined Figure 7 As shown, the airflow guiding assembly 1 for the humidity regulating device 2 further includes a drive unit 50. The drive unit 50 is disposed outside the housing 10 and is connected to the airflow guiding plate 30 in a transmission manner, thereby driving the airflow guiding plate 30 to rotate to a preset position.

[0055] Optionally, the drive unit 50 can be a structure that can provide driving force, such as a motor, cylinder, or hydraulic cylinder.

[0056] Optionally, see [link to relevant documentation] Figure 7 The guide plate 30 includes a plate body 31 and a transmission part 32. The plate body 31 is disposed within the housing 10. A first through hole is formed on the first side plate 111. The transmission part 32 passes through the first through hole, with one end connected to the drive part 50 and the other end connected to the plate body 31. Thus, the drive part 50 can transmit driving force to the plate body 31 through the transmission part 32, thereby causing the plate body 31 to rotate.

[0057] Optionally, the transmission part 32 includes a transmission rod 321. The transmission rod 321 passes through a first through hole, with its first end connected to the drive part 50 and its second end connected to the plate 31.

[0058] Optionally, the transmission unit 32 further includes a first connecting plate 322. The transmission rod 321 passes through the first through hole, and its first end is connected to the drive unit 50. The bottom surface of the first connecting plate 322 is connected to the second end of the transmission rod 321. The surface of the plate body 31 is connected to the first connecting plate 322. Optionally, the first connecting plate 322 is fastened to the surface of the plate body 31 by bolts. In this way, by connecting the first connecting plate 322 to the surface of the plate body 31, the connection area between the transmission unit 32 and the plate body 31 is indirectly increased, making the connection between the transmission unit 32 and the plate body 31 more stable.

[0059] Optionally, the transmission rod 321 and the first connecting plate 322 are integrally formed.

[0060] Optionally, see [link to relevant documentation] Figure 7 The guide plate 30 also includes a support portion 33. A second through hole is provided on the second side plate 112. The support portion 33 is rotatably inserted through the second through hole, and one end of the support portion 33 is connected to the plate body 31. The position of the support portion 33 is opposite to the position of the transmission portion 32. In this way, the support portion 33 supports the other side of the plate body 31, so that the plate body 31 rotates more smoothly and the plate surface is less likely to tilt.

[0061] Optionally, the support portion 33 includes a rotating member 331 and a second connecting plate 332. The rotating member 331 is rotatably disposed in the second through hole. One end of the second connecting plate 332 is connected to the second end of the rotating member 331. The plate surface of the plate body 31 is connected to the second connecting plate 332. Optionally, the second connecting plate 332 is fastened to the plate surface of the plate body 31 by bolts. In this way, by connecting the second connecting plate 332 to the plate surface of the plate body 31, the connection area between the support portion 33 and the plate body 31 is indirectly increased, which makes the connection between the support portion 33 and the plate body 31 more stable.

[0062] Optionally, the rotating part 331 and the second connecting plate 332 are integrally formed.

[0063] Combination Figure 8 and Figure 9 As shown, this embodiment of the present disclosure provides a humidity control device 2, which includes the flow guiding component 1 described above for the humidity control device 2.

[0064] Optionally, the humidity control device 2 further includes a housing 60. The housing 60 internally defines two air ducts, namely a first air duct and a second air duct. Each air duct has an air outlet 40 at both ends of the housing 10. When the airflow guiding assembly 1 forms two sets of air outlets, the two sets of air outlets of the airflow guiding assembly 1 are connected in series to the two air ducts, with the airflow guiding assembly 1 housed within the housing 60. Specifically, one air duct corresponds to the first air outlet 41 and the second air outlet 42, and the other air duct corresponds to the third air outlet 43 and the fourth air outlet 44.

[0065] Understandably, the series connection of the airflow guide component 1 divides the air duct into an outdoor air duct section and an indoor air duct section. The first air duct includes a first outdoor air duct section 62 and a first indoor air duct section 64; the second air duct includes a second outdoor air duct section 63 and a second indoor air duct section 65. By rotating the airflow guide plate 30, the first and second air ducts can be arranged in parallel, or in a cross-flow configuration where the first outdoor air duct section 62 connects to the second indoor air duct section 65, and the second outdoor air duct section 63 connects to the first indoor air duct section 64.

[0066] Optionally, the humidity control device 2 further includes a first partition plate 61. The first partition plate 61 is disposed between two air duct sections between the air guiding assembly 1 and the outdoor side of the housing 60, thereby dividing each air duct section into two chambers for housing the heat exchanger 90 and the outdoor fan 80, respectively.

[0067] Specifically, the lateral dimensions of the housing 10 of the airflow guide assembly 1 and the lateral dimensions of the first partition plate 61 are matched with the internal lateral dimensions of the outer shell 60. The first partition plate 61 divides the first outdoor air duct section 62 into a first heat exchange chamber 621 and a first outdoor fan chamber 622, and divides the second outdoor air duct section 63 into a second heat exchange chamber 631 and a second outdoor fan chamber 632. The first partition plate 61 has a first ventilation hole 611 and a second ventilation hole 612 to connect the first heat exchange chamber 621 and the first outdoor fan chamber 622, and to connect the second heat exchange chamber 631 and the second outdoor fan chamber 632.

[0068] See Figure 10 and Figure 11 The heat exchanger 90 includes a first heat exchanger 91 and a second heat exchanger 92. The first heat exchanger 91 is disposed within a first heat exchange chamber 621, and the second heat exchanger 92 is disposed within a second heat exchange chamber 631. Both the first heat exchanger 91 and the second heat exchanger 92 are coated with an adsorption coating. The coating is a solid desiccant.

[0069] The external fan 80 includes a first external fan 81 and a second external fan 82. The first external fan 81 is disposed in the first external fan cavity 622, and the second external fan 82 is disposed in the second external fan cavity 632.

[0070] The first indoor air duct section 64 includes a compressor chamber 641, in which a compressor 100 and a four-way valve 110 are disposed.

[0071] The second indoor side air duct section 65 includes an inner fan cavity 651, and an inner fan 70 is disposed in the inner fan cavity 651.

[0072] Optionally, the first side wall of the outer casing 60 is provided with an indoor air supply vent 66 and an indoor air return vent 67. The indoor air supply vent 66 corresponds to the indoor fan 70, and the indoor air return vent 67 corresponds to the compressor 100.

[0073] The second side wall of the outer casing 60 has a first outdoor air vent 68 and a second outdoor air vent 69. The second side wall and the first side wall are two opposite side walls in a third direction. The first outdoor air vent 68 corresponds to the first outdoor fan 81, and the second outdoor air vent 69 corresponds to the second outdoor fan 82.

[0074] The discharge port of compressor 100, four-way valve 110, second heat exchanger 92, throttling device 120, first heat exchanger 91 and suction port of compressor 100 are connected in sequence to form a complete refrigerant circulation loop.

[0075] The basic operating principle of the humidity control device 2: Taking refrigeration and dehumidification as an example, the indoor fan 70 and the second outdoor fan 82 operate. Combined with... Figure 10 As shown, the flow guide assembly 1 switches the flow path to crossflow mode. At this time, the hot, humid outdoor air passes sequentially through the first outdoor air vent 68 and the first heat exchanger 91. The hot, humid air is cooled and dehumidified at the first heat exchanger 91, thus forming dry, cool air. The indoor fan 70 provides power, while the first outdoor fan 81 does not operate. The dry, cool air passes through the second air vent 42 and the third air vent 43 of the flow guide assembly 1 and is blown into the room through the indoor air supply vent 66. The dry, cool, and turbid indoor air passes sequentially through the indoor return air vent 67, the first air vent 41 of the flow guide assembly 1, the fourth air vent 44, and the second heat exchanger 92. Due to the heating of the second heat exchanger 92, the dehumidifying material desorbs and regenerates, thus the dry, cool air absorbs moisture, forming hot, humid exhaust gas. The second outdoor fan 82 provides power to exhaust the hot, humid exhaust gas from the second outdoor air vent 69 to the outside. This is one small cycle.

[0076] After this small cycle is completed, the four-way valve 110 reverses. (Combined) Figure 11As shown, the flow guiding component 1 switches to the co-current flow mode. Simultaneously, the first outdoor fan 81 is turned on, and the second outdoor fan 82 is turned off. At this time, hot and humid outdoor air enters through the second outdoor vent 69 and passes through the second heat exchanger 92. The hot and humid air is cooled and dehumidified at the second heat exchanger 92 to form dry and cold air, which then passes through the fourth vent 44 and the third vent 43 of the flow guiding component 1 and enters the inner fan chamber 651 where the inner fan 70 is located. The inner fan 70 provides power, and the second outdoor fan 82 does not operate. The inner fan 70 blows dry and cold air into the room through the indoor air supply vent 66. The dry and cold turbid indoor air enters the compressor chamber 641 where the compressor 100 is located through the indoor return air vent 67. Then, it enters the first heat exchange chamber 621 where the first heat exchanger 91 is located through the first vent 41 and the second vent 42 of the flow guiding component 1. Due to the heating of the first heat exchanger 91, the dehumidifying material desorbs and regenerates, thus the dry and cold air absorbs moisture, thereby forming hot and humid exhaust gas. Powered by the first outdoor fan 81, the hot and humid exhaust gas is discharged outdoors through the first outdoor vent 68. This constitutes another small circulation.

[0077] The two small cycles above constitute a complete dehumidification and heat exchange cycle.

[0078] As can be seen from the above, the air is divided into left-right or up-down flow paths within the airflow guide assembly 1. The air flowing towards the heat exchanger 90 can fully contact the heat exchanger 90. The airflow is not obstructed, the airflow resistance is small, and thus the heat exchange efficiency of the heat exchanger 90 is high.
