These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0047] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0048] The fresh air duct is used to transport the air processed by the purification and filtering device to the indoor or heat exchanger of the fresh air system.

[0049] In the prior art, the fresh air in the fresh air duct needs to be transported to the indoor location or the heat exchanger of the fresh air system. For example, in cold or hot weather, if the fresh air is directly transported to the indoor location through the fresh air duct, the temperature of the fresh air will be very low or very high, affecting the indoor comfort. In order to ensure that the fresh air transported is warm air in cold weather and cool air in hot weather, the fresh air in the fresh air duct needs to be transported unidirectionally to the heat exchanger of the fresh air system. The fresh air is heat exchanged through the heat exchanger so that the blown fresh air has a comfortable temperature. At this time, it is necessary to avoid the fresh air in the fresh air duct from blowing directly into the indoor location. In order to control the direction of the fresh air, it is necessary to close the valve of the fresh air duct blowing directly into the indoor location, and open the valve of the fresh air duct blowing toward the heat exchanger. In the prior art, a valve switch is provided in each direction of the fresh air duct to control the flow direction of the fresh air in the fresh air duct.

[0050] However, since valve switches are provided on the existing fresh air ducts in each direction, multiple valves need to be opened or closed separately when controlling the fresh air direction, resulting in cumbersome operation.

[0051] In order to solve the technical problem that when controlling the direction of fresh air in existing fresh air ducts, multiple valves need to be opened or closed separately, resulting in cumbersome operation, the present application proposes a valve structure and a fresh air system, wherein the valve structure includes a valve body, a valve and a drive component.

[0052] An air inlet, a first air outlet, a second air outlet and a third air outlet are provided on the valve body. The air inlet is used to be connected with the fresh air inlet of the fresh air system, the first air outlet is used to be connected with the first fresh air outlet of the fresh air system, the second air outlet is used to be connected with the second fresh air outlet of the fresh air system, and the third air outlet is used to be connected with the heat exchanger of the fresh air system.

[0053] The valve is arranged on the valve body, and the driving member is connected to the valve to drive the valve to switch among a first position, a second position, a third position and a fourth position.

[0054] When in the first position, the valve connects the air inlet and the first air outlet, so that the fresh air entering the valve body is discharged to the first fresh air outlet; when in the second position, the valve connects the air inlet and the second air outlet, so that the fresh air entering the valve body is discharged to the second fresh air outlet; when in the third position, the valve connects the air inlet and the third air outlet, so that the fresh air entering the valve body is discharged to the heat exchanger; when in the fourth position, the valve closes the first air outlet, the second air outlet and the third air outlet.

[0055] The valve structure of the present application drives the valve to switch between the first position, the second position, the third position and the fourth position through a driving member, thereby realizing the delivery of fresh air to the first air outlet, the second air outlet, the third air outlet or closing the valve body. The first air outlet is used to be connected with the first fresh air outlet of the fresh air system, and the second air outlet is used to be connected with the second fresh air outlet of the fresh air system. The first fresh air outlet and the second fresh air outlet of the fresh air system can both lead into the room. The directions of the first fresh air outlet and the second fresh air outlet can be the same or different. The third air outlet is used to be connected with the heat exchanger of the fresh air system, so that when the valve is adjusted to the first position, the fresh air can be delivered to the first fresh air outlet of the fresh air system, when the valve is adjusted to the second position, the fresh air can be delivered to the second fresh air outlet of the fresh air system, and when the valve is adjusted to the third position, the fresh air can be delivered to the heat exchanger of the fresh air system, thereby realizing heat exchange of the fresh air, and when the valve is adjusted to the fourth position, the valve body is closed, that is, the fresh air duct of the fresh air system is closed.

[0056] Since the valve structure of the present application only needs to adjust the position of one valve to adjust the direction of the fresh air, thereby ensuring that the fresh air can directly flow into the room, into the heat exchanger, or realize the closure of the valve structure, compared with the existing fresh air duct that needs to open or close multiple valves to reverse the direction of the fresh air, the valve structure of the present application is simple to operate, reduces the number of valves to be operated, and only one valve needs to be operated, thereby improving the reversing efficiency of the fresh air in the fresh air duct and simplifying the operating process.

[0057] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0059] Reference Figures 1 to 3 As shown, an embodiment of the present application provides a valve structure, including a valve body 100 , a valve 200 and a driving member 300 .

[0060] The valve body 100 is provided with an air inlet 110, a first air outlet 120, a second air outlet 130 and a third air outlet 140 which are interconnected. The air inlet 110 is used to be connected with the fresh air inlet 411 of the fresh air system 400, the first air outlet 120 is used to be connected with the first fresh air outlet 412 of the fresh air system 400, the second air outlet 130 is used to be connected with the second fresh air outlet 413 of the fresh air system 400, and the third air outlet 140 is used to be connected with the heat exchanger 422 of the fresh air system 400.

[0061] The valve 200 is disposed on the valve body 100 , and the driving member 300 is connected to the valve 200 to drive the valve 200 to rotate relative to the valve body 100 to switch between a first position, a second position, a third position and a fourth position.

[0062] When in the first position, the valve 200 connects the air inlet 110 and the first air outlet 120, so that the fresh air entering the valve body 100 is discharged to the first fresh air outlet 412; when in the second position, the valve 200 connects the air inlet 110 and the second air outlet 130, so that the fresh air entering the valve body 100 is discharged to the second fresh air outlet 413; when in the third position, the valve 200 connects the air inlet 110 and the third air outlet 140, so that the fresh air entering the valve body 100 is discharged to the heat exchanger 422; when in the fourth position, the valve 200 closes the first air outlet 120, the second air outlet 130 and the third air outlet 140.

[0063] The valve structure of the present application includes a valve body 100, a valve 200 and a driving member 300. The valve body 100 is provided with an air inlet 110, a first air outlet 120, a second air outlet 130 and a third air outlet 140. The air inlet 110 is connected to the fresh air inlet 411 of the fresh air system 400. The fresh air inlet 411 is used to introduce air that needs to be filtered and purified into the fresh air system 400.

[0064] The purification and filtering device of the fresh air system 400 may be disposed in the valve body 100 , or may not be disposed in the valve body 100 , or may be disposed in a fresh air duct at other locations of the fresh air system 400 .

[0065] The first air outlet 120 is used to communicate with the first fresh air outlet 412 of the fresh air system 400, and the second air outlet 130 is used to communicate with the second fresh air outlet 413 of the fresh air system 400. The first fresh air outlet 412 and the second fresh air outlet 413 of the fresh air system 400 can be used to communicate with the indoor room, and the first fresh air outlet 412 and the second fresh air outlet 413 are used to discharge fresh air into the indoor room. The directions of the first fresh air outlet 412 and the second fresh air outlet 413 can be the same or different. The direction of the first fresh air outlet 412 can be directly toward the indoor room, such as toward the indoor floor, toward the user, etc. When the direction of the first fresh air outlet 412 is toward the user, the fresh air coming out of the first fresh air outlet 412 can blow directly into the user; the direction of the second fresh air outlet 413 can blow into the indoor room from the side, such as toward the indoor ceiling, indoor side wall, etc., so as to avoid the fresh air blowing directly on the user.

[0066] The third air outlet 140 is used to connect with the heat exchanger 422 of the fresh air system 400. The heat exchanger 422 of the fresh air system 400 is used to exchange heat for the fresh air, such as heating the fresh air or cooling the fresh air. After the fresh air passes through the heat exchanger 422, the fresh air is adjusted to a comfortable temperature and then delivered to the room, thereby improving the user experience and preventing the fresh air temperature from being too high or too low to affect the user comfort.

[0067] The valve structure of the present application drives the valve 200 to switch between the first position, the second position, the third position and the fourth position through the driving member 300, so as to realize the delivery of fresh air to the first air outlet 120, the second air outlet 130, the third air outlet 140 or close the valve body 100, the first air outlet 120 is used to communicate with the first fresh air outlet 412 of the fresh air system 400, the second air outlet 130 is used to communicate with the second fresh air outlet 413 of the fresh air system 400, the first fresh air outlet 412 and the second fresh air outlet 413 of the fresh air system 400 can both lead into the room, and the first fresh air outlet 412 and the second fresh air outlet 413 can lead into the room. The directions of 413 can be the same or different. The third air outlet 140 is used to connect with the heat exchanger 422 of the fresh air system 400, so that when the valve 200 is adjusted to the first position, the fresh air can be delivered to the first fresh air outlet 412 of the fresh air system 400. When the valve 200 is adjusted to the second position, the fresh air can be delivered to the second fresh air outlet 413 of the fresh air system 400. When the valve 200 is adjusted to the third position, the fresh air can be delivered to the heat exchanger 422 of the fresh air system 400, thereby realizing heat exchange of the fresh air. When the valve 200 is adjusted to the fourth position, the valve body 100 is closed.

[0068] Since the valve structure of the present application only needs to adjust the position of one valve 200 to adjust the direction of the fresh air, thereby ensuring that the fresh air can directly flow into the room, into the heat exchanger 422, or realize the closure of the valve structure, compared with the existing fresh air duct that needs to open or close multiple valves to reverse the fresh air, the valve structure of the present application is simple to operate, reduces the number of valves to be operated, and only one valve needs to be operated, thereby improving the reversing efficiency of the fresh air in the fresh air duct and simplifying the operating process.

[0069] It should be noted that, when in the first position, the valve 200 connects the air inlet 110 and the first air outlet 120, and the valve 200 can close the second air outlet 130 and the third air outlet 140 at the same time; when in the second position, the valve 200 connects the air inlet 110 and the second air outlet 130, and the valve 200 can close the first air outlet 120 and the third air outlet 140 at the same time; when in the third position, the valve 200 connects the air inlet 110 and the third air outlet 140, and the valve 200 can open the first air outlet 120 and the second air outlet 130 at the same time.

[0070] In other embodiments, the air inlet 110 is one port of the valve body 100 , the first air outlet 120 is another port of the valve body 100 , and the second air outlet 130 and the third air outlet 140 are respectively disposed on two opposite side walls of the valve body 100 .

[0071] In this embodiment, the valve body 100 is a pipe structure, and the valve body 100 has two ports. Since the air inlet 110 is one port of the valve body 100 and the first air outlet 120 is the other port of the valve body 100, when the valve 200 is driven to the first position, fresh air is discharged from the first air outlet 120. Since the first air outlet 120 and the air inlet 110 are arranged opposite to each other, the fresh air coming out of the first air outlet 120 is larger than the fresh air coming out of the second air outlet 130 located on the side wall. The speed of the fresh air coming out is higher, while the speed of the fresh air coming out of the second air outlet 130 is relatively reduced, and the wind speed is relatively gentle. Therefore, when the valve 200 is driven to the first position, the speed of the fresh air blown into the room is high, and when the valve 200 is driven to the second position, the speed of the fresh air blown into the room is low. Of course, the direction of the first fresh air outlet 412 and the second fresh air outlet 413 of the fresh air system 400 can also be adjusted, so that the wind direction can be changed when the valve 200 is driven to the first position or the second position.

[0072] In one embodiment, the valve 200 includes a rotating shaft 210 , a first baffle 220 , a baffle leaf 230 and a second baffle 240 . The rotating shaft 210 is rotatably connected to the valve body 100 . The first baffle 220 , the baffle leaf 230 and the second baffle 240 are all arranged on the rotating shaft 210 .

[0073] The valve body 100 is located between the first baffle 220 and the second baffle 240. The first baffle 220 is used to block the second air outlet 130. The first baffle 220 is provided with a first through hole 221, and the first through hole 221 is used to communicate with the second air outlet 130. The second baffle 240 is used to block the third air outlet 140. The second baffle 240 is provided with a second through hole 241, and the second through hole 241 is used to communicate with the third air outlet 140.

[0074] The baffle 230 is at least partially located in the inner cavity of the valve body 100 , and the baffle 230 is used to block or connect the inner cavity of the valve body 100 , so as to block two ports of the valve body 100 or connect the two ports of the valve body 100 .

[0075] The driving member 300 is connected to the rotating shaft 210 to drive the first baffle 220 , the baffle blade 230 and the second baffle 240 to rotate.

[0076] Reference Figure 1 As shown, when the valve 200 is in the first position, the driving member 300 drives the first baffle 220 to rotate to block the second air outlet 130 , drives the baffle 230 to rotate to communicate with the inner cavity of the valve body 100 , and drives the second baffle 240 to rotate to block the third air outlet 140 .

[0077] Reference Figure 5 As shown, when the valve 200 is in the second position, the driving member 300 drives the first baffle 220 to rotate until the first through hole 221 is connected to the second air outlet 130, drives the baffle 230 to rotate to block the inner cavity of the valve body 100, and drives the second baffle 240 to rotate to block the third air outlet 140.

[0078] Reference Figure 6 As shown, when the valve 200 is in the third position, the driving member 300 drives the first baffle 220 to rotate to block the second air outlet 130, drives the baffle 230 to rotate to block the inner cavity of the valve body 100, and drives the second baffle 240 to rotate to the second through hole 241 to communicate with the third air outlet 140.

[0079] Reference Figure 7 As shown, when the valve 200 is in the fourth position, the driving member 300 drives the first baffle 220 to rotate to block the second air outlet 130 , drives the baffle 230 to rotate to block the inner cavity of the valve body 100 , and drives the second baffle 240 to rotate to block the third air outlet 140 .

[0080] In this embodiment, the driving member 300 drives the rotating shaft 210 to rotate, so as to drive the first baffle 220 , the baffle blade 230 , and the second baffle 240 to rotate.

[0081] When the first baffle 220 rotates to block the second air outlet 130 , the baffle 230 rotates to communicate with the inner cavity of the valve body 100 , and the second baffle 240 rotates to block the third air outlet 140 , the valve 200 is located at the first position.

[0082] When the first baffle 220 rotates to connect the first through hole 221 with the second air outlet 130 , the baffle 230 rotates to block the inner cavity of the valve body 100 , and the second baffle 240 rotates to block the third air outlet 140 , the valve 200 is located at the second position.

[0083] When the first baffle 220 rotates to block the second air outlet 130, the baffle 230 rotates to block the inner cavity of the valve body 100, and the second baffle 240 rotates to connect the second through hole 241 with the third air outlet 140, the valve 200 is located at the third position.

[0084] When the first baffle 220 rotates to block the second air outlet 130, the baffle 230 rotates to block the inner cavity of the valve body 100, and the second baffle 240 rotates to block the third air outlet 140, the valve 200 is at the fourth position.

[0085] In another embodiment, a projection of the first baffle 220 toward the second baffle 240 is the same as a projection of the second baffle 240 toward the first baffle 220 .

[0086] In this embodiment, since the projection of the first baffle 220 toward the second baffle 240 and the projection of the second baffle 240 toward the first baffle 220 are the same, it is possible to ensure that the outer contours of the first baffle 220 and the second baffle 240 are the same, and can be both circular, rectangular, etc., to ensure that the rotating shaft 210 is subjected to the same force at the position of the first baffle 220 and the position of the second baffle 240.

[0087] In another embodiment, the shape of the first through hole 221 is the same as that of the second air outlet 130 , and the shape of the second through hole 241 is the same as that of the third air outlet 140 .

[0088] In this embodiment, since the shape of the first through hole 221 is the same as that of the second air outlet 130, the fresh air coming out of the first through hole 221 can be delivered to the second air outlet 130 at the maximum air volume. Similarly, the fresh air coming out of the second through hole 241 can be delivered to the third air outlet 140 at the maximum air volume.

[0089] In some embodiments, the second air outlet 130 and the third air outlet 140 are disposed opposite to each other.

[0090] In this embodiment, since the second air outlet 130 and the third air outlet 140 are arranged opposite to each other, the structural stability of the valve body 100 is improved, and the side walls of the valve body 100 are relatively symmetrical.

[0091] In some possible embodiments, the diameter of the first air outlet 120 is greater than the diameter of the second air outlet 130. In this embodiment, since the diameter of the first air outlet 120 is greater than the diameter of the second air outlet 130, the air volume of the first air outlet 120 is increased and the air volume of the second air outlet 130 is reduced, so that when the valve 200 is driven to the first position or the second position, the air volume of the air conditioning system can be changed.

[0092] In other possible embodiments, the driving member 300 is a motor. In this embodiment, the valve 200 is driven to rotate by the rotation of the motor, so that the position of the valve 200 is switched.

[0093] A second aspect of the embodiment of the present application provides a fresh air system 400, referring to Figure 8 As shown, the fresh air system 400 includes a shell 410 and an air conditioning device 420. The air conditioning device 420 is arranged in the shell 410. The air conditioning device 420 includes an air conditioning duct 421. A heat exchanger 422 is arranged in the air conditioning duct 421, and also includes any of the above-mentioned valve structures.

[0094] The shell 410 is provided with a fresh air inlet 411, a first fresh air outlet 412, and a second fresh air outlet 413. The fresh air inlet 411 is used to communicate with the outside, and the first fresh air outlet 412 and the second fresh air outlet 413 are both used to communicate with the inside of the room.

[0095] The air inlet 110 of the valve structure is connected to the fresh air inlet 411 , the first air outlet 120 of the valve structure is connected to the first fresh air outlet 412 , the second air outlet 130 of the valve structure is connected to the second fresh air outlet 413 , and the third air outlet 140 of the valve structure is connected to the heat exchanger 422 .

[0096] In the present embodiment, since the fresh air system 400 has any of the above-mentioned valve structures, the valve structure drives the valve 200 to switch between the first position, the second position, the third position and the fourth position through the driving member 300, so as to realize the fresh air being delivered to the first air outlet 120, the second air outlet 130, the third air outlet 140 or closing the valve body 100, the first air outlet 120 is used to communicate with the first fresh air outlet 412 of the fresh air system 400, the second air outlet 130 is used to communicate with the second fresh air outlet 413 of the fresh air system 400, the first fresh air outlet 412 and the second fresh air outlet 413 of the fresh air system 400 can both lead into the room, and the first fresh air outlet 120 can be connected to the second fresh air outlet 413 of the fresh air system 400. The directions of the third air outlet 412 and the second fresh air outlet 413 can be the same or different, and the third air outlet 140 is used to communicate with the heat exchanger 422 of the fresh air system 400, so that when the valve 200 is adjusted to the first position, the fresh air can be delivered to the first fresh air outlet 412 of the fresh air system 400, and when the valve 200 is adjusted to the second position, the fresh air can be delivered to the second fresh air outlet 413 of the fresh air system 400, and when the valve 200 is adjusted to the third position, the fresh air can be delivered to the heat exchanger 422 of the fresh air system 400, thereby realizing heat exchange of the fresh air, and when the valve 200 is adjusted to the fourth position, the valve body 100 is closed.

[0097] Since the fresh air system 400 of the present application only needs to adjust the position of a valve 200 to adjust the direction of the fresh air, thereby ensuring that the fresh air can directly flow into the room, into the heat exchanger 422, or realize the closure of the valve structure, compared with the existing fresh air system 400 which needs to open or close multiple valves to reverse the direction of the fresh air, the fresh air system 400 of the present application is simple to operate, reduces the number of valves to be operated, and only needs to operate one valve to change the direction of the fresh air, thereby improving the reversing efficiency of the fresh air in the fresh air duct and simplifying the operating process.

[0098] In other possible embodiments, an angle is formed between the air outlet direction of the first fresh air outlet 412 and the air outlet direction of the second fresh air outlet 413 .

[0099] In this embodiment, since an angle is formed between the air outlet direction of the first fresh air outlet 412 and the air outlet direction of the second fresh air outlet 413, the air outlet direction of the first fresh air outlet 412 is different from the air outlet direction of the second fresh air outlet 413. The air outlet direction of the first fresh air outlet 412 can be set to blow directly to the user, while the air outlet direction of the second fresh air outlet 413 can be set to not blow directly to the user. Therefore, the user can choose to blow the fresh air directly or not by switching the position of the valve 200, thereby improving the user experience.
