Description

Technical Field

[0001] The present application relates to the field of air treatment technology, and in particular to an air treatment device. Background Art

[0002] People spend nearly 90% of their time indoors, and indoor air quality has a significant impact on human health. Indoor air quality is often affected by volatile organic compounds (VOCs), carbon dioxide, smoke, dust, and bacteria. With increasing attention to air quality and energy conservation, air freshener products have emerged. Currently, the mainstream air freshener products on the market can be divided into two categories: bidirectional fresh air exchangers with heat recovery capabilities. These core components include heat exchangers, fresh air blowers, exhaust fans, and filters. These fresh air products are relatively expensive. Unidirectional fresh air blowers, whose core components consist solely of a fresh air blower and filters, are relatively cheap. However, the biggest drawback of unidirectional fresh air blowers is that they only deliver air but do not exhaust it, resulting in a less pronounced fresh air effect. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the purpose and implementation of this application clearer, the exemplary implementation of this application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only part of the embodiments of this application, not all of the embodiments.

[0033] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0034] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0036] The air treatment device of the present application mainly relates to new air-conditioning products, which can introduce outdoor fresh air into the room to realize indoor air replacement. At present, the mainstream new air-conditioning products on the market can be divided into two categories. One is a two-way flow fresh air exchanger with heat recovery function. The core components include heat exchange components, fresh air fans, exhaust fans, filters, etc. This type of fresh air product has a higher cost; the other is a unidirectional flow fresh air fan. The core components only include fresh air fans and filters. This type of fresh air product has a lower cost, but the biggest disadvantage of the unidirectional flow fresh air fan is that it cannot discharge indoor air to the outside, and the fresh air effect is not obvious.

[0037] This embodiment provides an air treatment device, including a fresh air module 10 for introducing fresh air from outdoors into indoors and discharging polluted air from indoors to outdoors.

[0038] Reference Figures 1 to 5 As shown, the fresh air module 10 includes: a shell 101 forming the general appearance of the fresh air module 10.

[0039] A fresh air inlet 1011 , a fresh air outlet 1012 , a dirty air inlet 1013 and a dirty air outlet 1014 are provided on the side wall of the housing 101 .

[0040] The housing 101 has a first cavity 1015 and a second cavity 1016. The first cavity 1015 is connected to the fresh air inlet 1011 and the polluted air inlet 1013; the second cavity 1016 is connected to the fresh air outlet 1012 and the polluted air outlet 1014.

[0041] The first cavity 1015 and the second cavity 1016 are connected via an opening 1021 .

[0042] The fresh air module 10 includes a first fan 103 . The first fan 103 is disposed in the second cavity 1016 , and an air inlet of the first fan 103 is disposed corresponding to the opening 1021 .

[0043] Reference Figure 4The arrows in the figure indicate the flow path of outdoor fresh air. In the air supply mode of the fresh air module 10, the fresh air inlet 1011 and the fresh air outlet 1012 are opened, the dirty air inlet 1013 and the dirty air outlet 1014 are closed, and the first fan 103 is started, so that the outdoor fresh air enters the first cavity 1015 through the fresh air inlet 1011, flows to the second cavity 1016 through the first fan 103, and is then delivered into the room through the fresh air outlet 1012.

[0044] Reference Figure 5 The arrows in the figure indicate the flow path of the dirty air. In the exhaust mode of the fresh air module 10, the fresh air inlet 1011 and the fresh air outlet 1012 are closed, the dirty air inlet 1013 and the dirty air outlet 1014 are opened, and the first fan 103 is started, so that the indoor dirty air enters the first chamber 1015 through the dirty air inlet 1013, is discharged to the second chamber 1016 through the first fan 103, and is discharged to the outside through the dirty air outlet 1014.

[0045] In the embodiment of the present application, the fresh air inlet 1011, the first cavity 1015, the opening 1021, the second cavity 1016 and the fresh air outlet 1012 are connected to form a fresh air channel. The dirty air inlet 1013, the first cavity 1015, the opening 1021, the second cavity 1016 and the dirty air outlet 1014 are connected to form a dirty air channel.

[0046] The first fan 103 is located on the fresh air passage and also on the dirty air passage.

[0047] In the air supply mode, the fresh air inlet 1011 and the fresh air outlet 1012 are opened, so that the fresh air channel is connected. Under the action of the first fan 103, the outdoor fresh air flows into the room through the fresh air channel.

[0048] In the exhaust mode, the dirty air inlet 1013 and the dirty air outlet 1014 are opened, so that the dirty air channel is connected. Under the action of the first fan 103, the indoor dirty air is discharged to the outside through the dirty air channel.

[0049] Therefore, in the air treatment device of the present application, the fresh air module 10 can not only realize the fresh air function of supplying fresh air into the room, but also realize the exhaust function of discharging indoor polluted air to the outside, which can avoid the problem of poor air treatment effect caused by the one-way flow fresh air fan in the prior art only having the fresh air function.

[0050] In addition, compared with the one-way fresh air fan, the air treatment device of the present application can realize the supply and exhaust operation of fresh air / dirty air through one fan by optimizing the flow channel design without increasing the cost, which has the advantages of low cost and good air treatment effect.

[0051] In addition, compared with the bidirectional flow fresh air exchanger, the air treatment device of the present application saves an exhaust fan, reduces product cost, and simplifies the product structure.

[0052] In some embodiments, continue to refer to Figure 3 , the housing 101 has a receiving cavity.

[0053] The fresh air module 10 may include a partition 102 , which is disposed in the accommodating chamber and divides the accommodating chamber into a first chamber 1015 and a second chamber 1016 . An opening 1021 is disposed on the partition 102 .

[0054] In some embodiments, the first cavity 1015 and the second cavity 1016 may be arranged one above the other, with the first cavity 1015 located at the top and the second cavity 1016 located at the bottom.

[0055] The first fan 103 is disposed in the second cavity 1016 , and the housing 101 can be easily disassembled from below to perform maintenance on the first fan 103 .

[0056] In other embodiments, the first cavity 1015 may be located below the second cavity 1016 ; or the first cavity 1015 and the second cavity 1016 may be arranged laterally.

[0057] In some embodiments, the dirty air inlet 1013 and the fresh air outlet 1012 are connected to the room through air ducts.

[0058] Reference Figure 6 The dirty air inlet 1013 and the fresh air outlet 1012 are arranged on the same side wall of the shell 101, which is convenient for installing the indoor air duct on the same side of the shell 101 during on-site installation.

[0059] In some embodiments, the fresh air inlet 1011 and the dirty air outlet 1014 are connected to the outdoor space through air ducts.

[0060] Reference Figure 7 , the fresh air inlet 1011 and the dirty air outlet 1014 are located on the same side wall of the housing 101. In this way, it is convenient to install the outdoor air duct on the same side of the housing 101 during on-site installation.

[0061] In some embodiments, first fan 103 is a centrifugal fan. Since fresh air module 10 is typically installed indoors, centrifugal fans offer low noise, preventing noise from impacting the user experience. Furthermore, since the fresh air and dirty air ducts are relatively long, centrifugal fans can overcome duct wind resistance and effectively move air.

[0062] According to an embodiment of the present application, the suction side of the first fan 103 corresponds to the opening 1021 , so that the air in the first cavity 1015 can flow to the first fan 103 through the opening 1021 .

[0063] In some embodiments, reference Figure 2 and Figure 7The fresh air module 10 includes a fresh air flange 104 corresponding to the fresh air inlet 1011 and the dirty air outlet 1014 and used to communicate with the outdoor space.

[0064] By connecting one end of the air duct to the fresh air flange 104 and extending the other end of the air duct to the outdoors, the fresh air inlet 1011 and the dirty air outlet 1014 can be connected to the outdoors.

[0065] In the prior art, the fresh air inlet 1011 connects to the outside through a set of flanges and air ducts, while the dirty air outlet 1014 connects to the outside through another set of flanges and air ducts. This requires two holes in the user's wall for the air ducts. In the present application, the fresh air inlet 1011 and the dirty air outlet 1014 connect to the outside through the same flange and air duct, reducing both the number of holes in the user's wall and the number of air ducts, thus lowering installation costs.

[0066] The fresh air flange 104 is connected to the outer wall of the housing 101. By setting a fresh air flange 104 corresponding to the fresh air inlet 1011 and the dirty air outlet 1014, the fresh air inlet 1011 and the dirty air outlet 1014 are connected to the outdoor space, and then the first cavity 1015 and the second cavity 1016 are connected to the outdoor space.

[0067] The fresh air module 10 is only provided with one fresh air flange 104. When actually installed outside the factory, only one fresh air outlet needs to be reserved to connect the air duct to the outside, which can reduce the number of holes opened in the user's wall and the number of air ducts.

[0068] It is understandable that, regarding the number and arrangement of the fresh air flanges 104 , it is also possible to adopt a method in which one fresh air flange 104 is arranged corresponding to the fresh air inlet 1011 and the other fresh air flange 104 is arranged corresponding to the dirty air outlet 1014 .

[0069] In some embodiments, a through hole is provided on the side wall of the housing 10 , a portion of the through hole is a fresh air inlet 1011 , and another portion of the through hole is a dirty air outlet 1014 .

[0070] The fresh air flange 104 is connected to the housing 10 corresponding to the through hole.

[0071] A partition 1041 is provided in the fresh air flange 104 . One end of the partition 1041 close to the housing 10 abuts against the partition plate 102 .

[0072] In some embodiments, a through hole is provided on the side wall of the housing 10 , and an isolation portion is provided in the through hole, which separates the through hole into a fresh air inlet 1011 and a dirty air outlet 1014 .

[0073] The inner sidewall of the isolation portion abuts against the partition plate 102 .

[0074] The fresh air flange 104 is connected to the housing 10 corresponding to the through hole.

[0075] A partition 1041 is provided in the fresh air flange 104. One end of the partition 1041 close to the housing 10 abuts against the isolation portion.

[0076] In some embodiments, reference Figure 4 、 5 7. The fresh air module 10 includes a fresh air inlet valve 105. The fresh air inlet valve 105 is disposed in the fresh air flange 104 and is used to open or close the fresh air inlet 1011.

[0077] Projected on a plane orthogonal to the axis of the fresh air flange 104 , the inner contour of the fresh air flange 104 can be divided into a first part and a second part by the partition 1041 , the first part corresponds to the fresh air inlet 1011 and the second part corresponds to the dirty air outlet 1014 .

[0078] The fresh air inlet valve 105 is connected to the first portion. One end of the fresh air inlet valve 105 close to the partition 1041 is rotatably connected to the fresh air flange 104 to open or close the fresh air inlet 1011.

[0079] The fresh air module 10 may include a dirty air outlet air valve 106 . The dirty air outlet air valve 106 is disposed in the fresh air flange 104 and is used to open or close the dirty air outlet 1014 .

[0080] The dirty air outlet air valve 106 is connected to the second portion. One end of the dirty air outlet air valve 106 close to the partition 1041 is rotatably connected to the fresh air flange 104 to open or close the dirty air outlet 1014.

[0081] The fresh air inlet valve 105 and the dirty air outlet valve 106 both include blades. The shape of the blades of the fresh air inlet valve 105 is the same as that of the first part. The shape of the blades of the dirty air outlet valve 106 is the same as that of the second part.

[0082] The blades rotate under the drive of the motor.

[0083] In the air supply mode, the blades of the fresh air inlet air valve 105 are in the open state, so that the fresh air flange 104 is connected to the fresh air inlet 1011; the blades of the dirty air outlet air valve 106 are in the closed state, so that the fresh air flange 104 is not connected to the dirty air outlet 1014.

[0084] In exhaust mode, the blades of the fresh air inlet air valve 105 are in a closed state, so that the fresh air flange 104 is not connected to the fresh air inlet 1011; the blades of the dirty air outlet air valve 106 are in an open state, so that the fresh air flange 104 is connected to the dirty air outlet 1014.

[0085] In some embodiments, as Figure 4 、 5 The fresh air module 10 includes: a fresh air outlet air valve 107, and the fresh air outlet air valve 107 is used to open or close the fresh air outlet 1012.

[0086] The fresh air module 10 includes a dirty air inlet valve 108 , which is used to open or close the dirty air inlet 1013 .

[0087] An air outlet flange is provided on the housing 10 at positions corresponding to the fresh air outlet 1012 and the dirty air inlet 1013. A fresh air outlet air valve 107 and a dirty air inlet air valve 108 are respectively provided in the air outlet flange.

[0088] In air supply mode, refer to Figure 4 , the fresh air outlet valve 107 is in the open state, so that the fresh air outlet 1012 is open. The dirty air inlet valve 108 is in the closed state, so that the dirty air inlet 1014 is closed; in exhaust mode, refer to Figure 5 , the fresh air outlet air valve 107 is in a closed state, so that the fresh air outlet 1012 is closed. The dirty air inlet air valve 108 is in an open state, so that the dirty air inlet 1014 is open.

[0089] By setting the fresh air inlet air valve 105, the dirty air outlet air valve 106, the fresh air outlet air valve 107, and the dirty air inlet air valve 108, the opening or closing of the fresh air inlet 1011, the dirty air outlet 1014, the fresh air outlet 1012, and the dirty air inlet 1013 can be controlled, which facilitates the switching of air supply and exhaust according to the indoor conditions.

[0090] In the air supply mode, the fresh air inlet air valve 105 and the fresh air outlet air valve 107 are in the open state. At this time, the fresh air inlet 1011, the first chamber 1015, the first fan 103, the second chamber 1016, and the fresh air outlet 1012 form a fresh air channel. The first fan 103 drives the air to make the outdoor fresh air flow into the room. At the same time, the dirty air inlet air valve 108 and the dirty air outlet air valve 106 are in the closed state, avoiding the impact caused by the indoor dirty air mixing into the fresh air channel.

[0091] In exhaust mode, the dirty air inlet valve 108 and the dirty air outlet valve 106 are in the open state. At this time, the dirty air inlet 1013, the first chamber 1015, the first fan 103, the second chamber 1016, and the dirty air outlet 1014 form a dirty air channel. The first fan 103 drives the air to discharge the indoor dirty air out of the room. At the same time, the fresh air inlet valve 105 and the fresh air outlet valve 107 are in the closed state, avoiding the impact of fresh air mixing into the new and dirty air channel.

[0092] In some embodiments, reference Figure 2 and Figure 3The fresh air module 10 includes a filter 109 disposed on one side of the second cavity 1016 near the fresh air outlet 1012 for filtering outdoor fresh air; a slide is provided on the wall of the shell 101, and the filter 109 is plugged into the slide.

[0093] By providing a slideway on the wall of the housing 101, the installation and removal of the filter 109 are facilitated. This embodiment defines that the filter 109 is installed on one side of the second cavity 1016 near the fresh air outlet 1012. Furthermore, along the air flow direction, the fresh air inlet 1011 and the first fan 103 are located on one side of the filter 109, and the fresh air outlet 1012 is located on the other side of the filter 109, so as to ensure that the filter 109 filters the outdoor fresh air.

[0094] In some embodiments, reference Figure 1 and Figure 2 The housing 101 includes a housing body 1017. The housing body 1017 is provided with an opening.

[0095] The housing 101 includes a maintenance panel 1018, which is connected to the opening of the housing body 1017. The maintenance panel 1018 is detachably connected to the housing body 1017. In this way, the maintenance panel 1018 can be easily removed to repair the components in the housing 10.

[0096] The maintenance panel 1018 is located at the bottom of the housing 101 to facilitate removal of the maintenance panel 1018 from the bottom when the fresh air module 10 is ceiling-mounted or wall-mounted.

[0097] In some embodiments, the first fan 103 is connected to the maintenance plate 1018. Thus, when the maintenance plate 1018 is removed, the first fan 103 is removed along with the maintenance plate 1018.

[0098] In some embodiments, the filter 109, the first fan 103, and the maintenance panel 1018 are connected to form an assembly. The first fan 103, the filter 109, and the maintenance panel 1018 are integrated. After the maintenance panel 1018 is removed, the first fan 103 and the filter 109 can be directly removed for replacement or maintenance.

[0099] In some embodiments, reference Figures 8 to 11 As shown, the air handling device may include an air conditioning indoor unit. The fresh air outlet 1012 and the polluted air inlet 1013 of the fresh air module 10 may be connected to the air conditioning indoor unit. Fresh air from the fresh air module 10 is delivered to the indoor space via the air conditioning indoor unit. Polluted air from the indoor space flows through the air conditioning indoor unit to the fresh air module 10.

[0100] The following is an introduction to the indoor unit of a ducted air conditioner:

[0101] The ducted air conditioner 20 includes a housing 21. The side walls of the housing 21 are provided with a return air port 211 and an air supply port 212. For example, the rear wall of the housing 21 is provided with the return air port 211, and the front wall of the housing 21 is provided with the air supply port 212.

[0102] A heat exchange air duct 213 is provided in the housing 21 , communicating with the return air port 211 and the supply air port 212 .

[0103] The duct air conditioner 20 includes a second fan 22. The second fan 22 is provided in the housing 21 corresponding to the return air port 211. The second fan 22 is used to drive air flow.

[0104] The duct air conditioner 20 may include a heat exchanger 23. The heat exchanger 23 is provided in the heat exchange air duct 213 corresponding to the air supply port 212, and is used for heat exchange with the air driven by the second fan 22.

[0105] In some embodiments, a partition is provided within the housing 21, dividing the heat exchange duct into an air inlet chamber and an air outlet chamber. The return air port 211 communicates with the air inlet chamber, and the second fan 22 is located within the air inlet chamber. The supply air port 212 communicates with the air outlet chamber, and the heat exchanger 23 is located within the air outlet chamber.

[0106] In some embodiments, the housing 21 may be provided with a first communication port 201 communicating with the heat exchange air duct 213 . The first communication port 201 is communicated with the fresh air outlet 1012 .

[0107] The outdoor fresh air blown out from the fresh air outlet 1012 of the fresh air module 10 enters the heat exchange air duct 213 of the air duct unit 20 through the first connecting port 201 , and is then blown into the room through the air supply port 212 of the air duct unit 20 .

[0108] The housing 21 may be provided with a second communication port 202 communicating with the heat exchange air duct 213 . The second communication port 202 is communicated with the dirty air inlet 1013 .

[0109] The indoor polluted air enters the heat exchange air duct 213 from the return air port 211 of the air duct unit, then flows to the fresh air module 10 through the second connecting port 202, and is finally discharged to the outside by the fresh air module 10.

[0110] In the present application, the fresh air outlet 1012 and the polluted air inlet 1013 of the fresh air module 10 are connected to the duct machine 20, and the duct machine 20 realizes the connection between the indoor polluted air and the fresh air module 10, thereby avoiding the problem of needing to open an air outlet indoors when the fresh air module 10 is directly connected to the indoor space through the air duct.

[0111] In some embodiments, the first communication port 201 is in communication with a portion of the heat exchange air duct 213 located on the windward side of the heat exchanger 23 .

[0112] That is, the first communication port 201 is in communication with the heat exchange air duct 213 on the upstream side of the heat exchanger 23 .

[0113] Reference Figure 10 In the figure, the straight arrows indicate the flow path of indoor air, and the curved arrows indicate the flow path of outdoor fresh air. When the duct unit 20 and the fresh air module 10 are running at the same time, in the air supply mode, the outdoor fresh air can flow into the heat exchange duct of the duct unit 20 through the fresh air channel and the first connecting port 210 of the fresh air module 10, and then mix with the indoor air from the return air port 211 of the duct unit 20, and continue to be delivered to the room through the heat exchanger 23.

[0114] On the one hand, the mixing of outdoor fresh air and indoor air can reduce the temperature difference between the outdoor fresh air and the indoor air. On the other hand, the outdoor fresh air passes through the heat exchanger 23 to further reduce the temperature difference between the outdoor fresh air and the indoor air, thereby avoiding the discomfort caused to the user by directly introducing fresh air when the temperature difference between indoor and outdoor is large.

[0115] In some embodiments, the first communication port 201 is disposed corresponding to the air suction side of the second fan 22 .

[0116] The second fan 22 can be a centrifugal fan. The first connecting port 201 is positioned directly opposite the volute inlet of the second fan 22, thereby maximizing the length of the mixing path between the outdoor fresh air and the indoor air, thereby improving mixing efficiency. Furthermore, the second fan 22 can provide a driving force for the flow of the outdoor fresh air, thereby improving the delivery efficiency of the outdoor fresh air.

[0117] In some embodiments, the second communication port 202 is communicated with a portion of the heat exchange air duct 213 located on the windward side of the heat exchanger 23 .

[0118] That is, the second communication port 202 is communicated with the heat exchange air duct 213 on the upstream side of the heat exchanger 23 .

[0119] Reference Figure 11 The arrows in the figure indicate the flow path of indoor air. When the duct air conditioner 20 and the fresh air module 10 are running at the same time, in the exhaust mode, the indoor air enters the heat exchange duct 213 from the return air port 211 of the duct air conditioner 20, and is then divided into two parts. One part continues to exchange heat in the duct air conditioner 20 and is then sent to the room, and the other part flows to the dirty air channel of the fresh air module 10 through the second connecting port 202 and is finally discharged to the outside.

[0120] In the present application, since the second connecting port 202 is located upstream of the heat exchanger 23, the air flowing to the fresh air module 10 through the second connecting port 202 will not pass through the heat exchanger 23, thereby avoiding energy waste.

[0121] In some embodiments, the second communication port 202 is communicated with a portion of the heat exchange duct located between the fan and the heat exchanger.

[0122] The fresh air module 10 of the above-mentioned air treatment device has the functions of both supplying and exhausting air. This fresh air module 10 can be used alone to deliver fresh air to the room and discharge polluted air; the fresh air module 10 and the duct machine 20 can also be softly connected through the air duct and installed on the side of the duct machine 20.

[0123] Regarding the operation mode of the above-mentioned fresh air module 10, when the fresh air is turned on, the dirty air inlet air valve 108 and the dirty air outlet air valve 106 are opened, the fresh air inlet air valve 105 and the fresh air outlet air valve 107 are closed, and the first fan 103 is started to discharge the indoor dirty air into the room and to the outside. After running t1, the fresh air inlet air valve 105 and the fresh air outlet air valve 107 are opened, the dirty air inlet air valve 108 and the dirty air outlet air valve 106 are closed, and the first fan 103 is started to lead the outdoor fresh air into the room. After t2, the dirty air inlet valve 108 and the dirty air outlet valve 106 are opened, the fresh air inlet valve 105 and the fresh air outlet valve 107 are closed, and the first fan 103 is started, exhausting the indoor dirty air and discharging it outdoors. After t3, the fresh air inlet valve 105 and the fresh air outlet valve 107 are opened, the dirty air inlet valve 108 and the dirty air outlet valve 106 are closed, and the first fan 103 is started, drawing outdoor fresh air into the room, thus achieving a cycle of introducing outdoor fresh air and exhausting indoor dirty air. When the fresh air is turned off, the wired controller turns off the fresh air, closes the dirty air inlet valve 108 and the dirty air outlet valve 106, closes the fresh air inlet valve 105 and the fresh air outlet valve 107, and shuts down the first fan 103. The values ​​of t1, t2, and t3 are determined based on the indoor space, air volume, and other actual conditions.
