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

[0036] 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.

[0037] As described in the background technology, the fresh air system includes a fresh air module and outdoor air inlet pipes respectively connected to the fresh air modules. The fresh air module introduces outdoor air through the outdoor air inlet pipe, and the fresh air is discharged into the room after being filtered and purified by the fresh air module.

[0038] However, such an arrangement means that the fresh air system can only introduce fresh air from the outside, which is not convenient for circulating and purifying the indoor air.

[0039] Based on this, the present application provides a fresh air system and an air conditioner. The fresh air system is provided with an opening and closing component so that the rotating part of the opening and closing component is rotatably embedded in the accommodating cavity of the air inlet pipe. Therefore, when the fresh air component is running, the rotating part can be used to control the air of at least one of the outdoor environment and the indoor environment to be discharged through the air outlet of the fresh air component, thereby realizing the circulation and purification of the indoor air, as well as the introduction of outdoor air and the circulation and purification of indoor air at the same time, which is more convenient to use.

[0040] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments may exist independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0041] Reference Figures 1 to 6 As shown, the fresh air system provided by the embodiment of the present application includes a fresh air component 100, an air inlet duct 200 and an opening and closing component 300. The fresh air component 100 has a connected air outlet 110 and an air inlet 120. The two ends of the air inlet duct 200 are respectively used to communicate with the outdoor environment and the indoor environment. The air inlet duct 200 has a accommodating cavity 231, and the air inlet 120 is connected to the accommodating cavity 231. The opening and closing component 300 includes a rotating member 310 and a driving member 320 that are interconnected. The rotating member 310 is rotatably embedded in the accommodating cavity 231.

[0042] The driving member 320 is configured to drive the rotating member 310 to rotate so as to connect at least one of the two ends of the air inlet duct 200 with the air inlet port 120 .

[0043] It is understandable that the fresh air system is disposed as a whole in an air conditioning device, such as a wall-mounted air conditioner or a vertical air conditioner with cooling and heating functions, or a fresh air blower, etc., to condition the indoor air. In this application, the fresh air system is described by taking the fresh air system disposed in the indoor unit of a ceiling-mounted air conditioner as an example.

[0044] The ceiling type air conditioner indoor unit is Figure 1 The air conditioner body 400 shown in the figure has a heat exchange component 410 inside. The heat exchange component 410 and the fresh air system are relatively independently arranged. The air entering the air conditioner body 400 can be heated or cooled by the heat exchange component 410. The fresh air system is arranged on one side of the heat exchange component 410 to discharge the air introduced from the outside or the air circulated indoors. When the heat exchange component 410 and the fresh air system are operated at the same time, the airflows discharged by the two can be mixed after being discharged, so that the air output of the air conditioner is softer and closer to the room temperature, thereby improving the user experience.

[0045] The fresh air assembly 100 is a conventional fresh air assembly 100 in the prior art, which generally includes a third housing, a filter and an air extractor, the filter and the air extractor are arranged in the third housing, the air inlet 120 and the air outlet 110 are both provided on the third housing and are connected to the third housing. The two ends of the third housing are the air inlet 120 and the air outlet 110, respectively, and the air extractor and the filter are arranged in the housing to extract air from the air inlet 120 through the air extractor, and then discharge from the air outlet 110 after being filtered by the filter.

[0046] The air inlet pipe 200 is connected to the air inlet port 120. Specifically, the two ends of the air inlet pipe 200 are respectively connected to the outdoor environment and the indoor environment, and a receiving cavity 231 is formed somewhere between the two ends of the air inlet pipe 200. The air inlet pipe 200 is provided with a connecting port connected to the receiving cavity 231 at this location, and the connecting port can be connected to the two ends of the air inlet pipe 200 through the receiving cavity 231.

[0047] In this way, the accommodating cavity 231 can be used as the intersection of one end of the air inlet duct 200 connected to the outdoor environment, one end of the air inlet duct 200 connected to the indoor environment and the air inlet 120. An opening and closing component 300 is set, and the rotating part 310 of the opening and closing component 300 is rotatably embedded in the accommodating cavity 231, and the driving part 320 of the opening and closing component 300 is connected to the rotating part 310, and the rotating part 310 is driven to rotate in the accommodating cavity 231 by the driving part 320.

[0048] As the rotating member 310 rotates in the accommodating chamber 231, the end of the air inlet pipe 200 connected to the outdoor environment can be connected to the air inlet 120, and the end of the air inlet pipe 200 connected to the indoor environment can be blocked. Alternatively, the end of the air inlet pipe 200 connected to the indoor environment can be connected to the air inlet 120, and the end of the air inlet pipe 200 connected to the outdoor environment can be blocked. Both ends of the air inlet pipe 200 can also be connected, so that the air inlet 120 is connected to the end of the air inlet pipe 200 connected to the outdoor environment and the end of the air inlet pipe 200 connected to the indoor environment are simultaneously connected.

[0049] In this regard, the driving member 320 can be set as a manual member to manually drive the rotating member 310 to rotate, so as to realize the opening and closing control of the air inlet duct 200. The driving member 320 can also be set as an electric member, and a controller can be set on the opening and closing component 300 to electrically connect the controller to the driving member 320. The driving member 320 can be controlled by the controller to drive the rotating member 310 to rotate by itself. This application does not impose any restrictions on this.

[0050] Furthermore, when the fresh air system is used, it can cooperate with the heat exchange component 410 in the air conditioner body 400 to achieve a variety of air outlet types, such as only discharging outdoor fresh air, only circulating indoor air, discharging indoor and outdoor mixed fresh air, discharging outdoor fresh air mixed with heat exchange air, discharging indoor air mixed with heat exchange air, and discharging indoor and outdoor mixed fresh air and heat exchange air at the same time.

[0051] Therefore, the present application provides a fresh air system by setting an opening and closing component 300, so that the rotating part 310 of the opening and closing component 300 is rotatably embedded in the accommodating cavity 231 of the air inlet pipe 200, and the two ends of the air inlet pipe 200 are respectively connected with the outdoor environment and the indoor environment, and the air inlet pipe 200 is connected with the air inlet 120 of the fresh air component 100 at the accommodating cavity 231. Therefore, when the fresh air component 100 is running, the driving part 320 can be used to drive the rotating part 310 to rotate in the accommodating cavity 231 to connect the outdoor environment with the air inlet 120, or to connect the indoor environment with the air inlet 120, or to connect the indoor environment and the outdoor environment with the air inlet 120 at the same time, so as to control the air in at least one of the outdoor environment and the indoor environment to be discharged through the air outlet 110 of the fresh air component 100. The present application can control the connection or disconnection of the indoor environment and outdoor environment airflow with the fresh air component 100 by only setting a rotating part 310, thereby realizing the circulation and purification of indoor air, as well as the introduction of outdoor air and circulation and purification of indoor air at the same time, which is more convenient to use.

[0052] In some embodiments, reference Figures 2 to 6 As shown, the outer wall of the rotating member 310 is adapted to abut against the inner wall of the accommodating cavity 231 , and a ventilation cavity 314 is provided in the rotating member 310 . The rotating member 310 is provided with a first communication port 311 , a second communication port 312 and a third communication port 313 which are connected to the ventilation cavity 314 .

[0053] The driving member 320 is configured to drive the rotating member 310 to rotate so that the rotating member 310 switches between a first position, a second position and a third position. In the first position, the first connecting port 311, the second connecting port 312 and the third connecting port 313 are all connected to the accommodating chamber 231. In the second position, the first connecting port 311 is closed by the inner wall, and the second connecting port 312 and the third connecting port 313 are connected to the accommodating chamber 231. In the third position, the second connecting port 312 is closed by the inner wall, and the first connecting port 311 and the third connecting port 313 are connected to the accommodating chamber 231.

[0054] It should be noted here that Figures 4 to 8 The straight arrows in the middle indicate the direction of air flow.

[0055] It can be understood that the first communication port 311, the second communication port 312 and the third communication port 313 are sequentially arranged adjacently on three sides of the rotating member 310 in the circumferential direction, and the remaining side of the rotating member 310 is used to block the air inlet pipe 200 or the air inlet 120. In this way, the outer wall of the rotating member 310 is adapted to abut against the inner wall of the accommodating chamber 231, and a certain sealing performance can be ensured between the rotating member 310 and the accommodating chamber 231 when the rotating member 310 rotates or is stationary, so that as much airflow in the air inlet pipe 200 as possible flows from the first communication port 311 and the second communication port 312 of the rotating member 310 to the third communication port 313, so that the air outlet effect of the fresh air system is better.

[0056] Among them, Figure 4 As shown, at this time, the rotating member 310 is in the first position, the third connecting port 313 of the rotating member 310 is aligned with and connected to the air inlet 120, the first connecting port 311 is aligned with one end of the air inlet pipe 200 connected to the indoor environment, so as to connect the indoor environment with the fresh air component 100 through the air inlet pipe 200, and the second connecting port 312 is aligned with one end of the air inlet pipe 200 connected to the outdoor environment, so as to connect the outdoor environment with the fresh air component 100 through the air inlet pipe 200, so that when the fresh air component 100 is running, equal amounts of air from the outdoor environment and the indoor environment can be introduced into the fresh air component 100 at the same time.

[0057] And, if Figure 5 As shown, at this time, the rotating member 310 is in the second position, the second connecting port 312 of the rotating member 310 is aligned with and connected to the air inlet 120, the third connecting port 313 is aligned with one end of the air inlet pipe 200 connected to the indoor environment, so as to connect the indoor environment with the fresh air component 100 through the air inlet pipe 200, and the first connecting port 311 is toward the side of the air inlet pipe 200 away from the connecting port, so that the air inlet pipe 200 blocks the first connecting port 311, and the rotating member 310 also blocks one end of the air inlet pipe 200 connected to the outdoor environment, so that when the fresh air component 100 is running, only the air circulation of the indoor environment can be introduced into the fresh air component 100.

[0058] In addition, if Figure 6 As shown, at this time, the rotating member 310 is in the third position, the first connecting port 311 of the rotating member 310 is aligned with and connected to the air inlet 120, the third connecting port 313 is aligned with one end of the air inlet pipe 200 connected to the outdoor environment, so as to connect the outdoor environment with the fresh air component 100 through the air inlet pipe 200, and the second connecting port 312 is toward the side of the air inlet pipe 200 away from the connecting port, so that the air inlet pipe 200 blocks the second connecting port 312, and the rotating member 310 also blocks one end of the air inlet pipe 200 connected to the indoor environment, so that when the fresh air component 100 is running, only air from the outdoor environment can be introduced into the fresh air component 100.

[0059] Further, in some embodiments, referring to Figure 7 and Figure 8 As shown, the driving member 320 is further configured to control the rotating member 310 to stop at a transition position, which is between any two of the first position, the second position and the third position.

[0060] When the rotating member 310 is in the transition position, at least one of the first communication port 311 , the second communication port 312 and the third communication port 313 is partially communicated with the accommodating chamber 231 .

[0061] It can be understood that when the rotating member 310 switches between the first position, the second position and the third position, the rotating member 310 only controls whether to discharge one of the indoor wind and the outdoor wind, but cannot adjust the respective discharge ratios of the indoor wind and the outdoor wind. A transition position is set for this purpose. When the rotating member 310 stops at the transition position, the discharge ratio of the indoor wind and the outdoor wind can be adjusted according to the ratio of the intersection area between the corresponding connecting port and the air inlet pipe 200.

[0062] For example, Figure 7 As shown, at this time, the rotating member 310 stops at the transition position shown in the current figure, which is halfway from the first position to the second position (or halfway from the second position to the first position). At this time, the end of the air inlet pipe 200 connected to the indoor environment is completely connected to the fresh air component 100 through the first connecting port 311 and the third connecting port 313, while the end of the air inlet pipe 200 connected to the outdoor environment is only connected to half of the second connecting port 312. In this way, when the rotating member 310 is in the current transition position, the indoor air accounts for about three quarters of the air discharged by the fresh air component 100, and the outdoor air accounts for about one quarter.

[0063] It needs to be explained here. Figure 7 The rotating member 310 is only shown to be in a transition position between the first position and the second position, which does not exclude that the rotating member 310 may also be in a transition position between the first position and the third position, or may be in a transition position between the first position and the second position. In addition, the present application does not limit the specific rotation angle of the rotating member 310 relative to the air inlet pipe 200 when the rotating member 310 is in a certain transition position, so as to realize the stepless adjustment control of the mixed air outlet ratio of the air inlet component by the rotating member 310.

[0064] also, Figure 8The rotating member 310 is shown in a transition position between the first position and the second position. In this transition position, the first connecting port 311 is aligned with the end of the air inlet pipe 200 connected to the outdoor environment, the second connecting port 312 is aligned with the end of the air inlet pipe 200 connected to the indoor environment, the third connecting port 313 is away from the fresh air component 100 and blocked by the air inlet pipe 200, and the rotating member 310 blocks the connection port. At this time, the indoor environment and the outdoor environment can be disconnected from the fresh air component 100 at the same time through the rotating member 310. Whether the fresh air component 100 is running or not, no air will be discharged, and when the fresh air component 100 is not running, the air flow will not escape from the air outlet 110 of the fresh air component 100.

[0065] In addition, in some embodiments, reference Figure 2 and Figure 3 As shown, the opening and closing assembly 300 further includes a transmission member 330, the output end of the driving member 320 is connected to the transmission member 330, and the transmission member 330 is partially plugged into the air inlet pipe 200 to be connected to the rotating member 310 via the air inlet pipe 200. In this way, it is easy to realize that the driving member 320 controls the rotation of the rotating member 310 in the accommodating cavity 231 outside the accommodating cavity 231, so that the structure of the fresh air system is more reasonable and compact.

[0066] The transmission member 330 is a pair of meshing gears, the output end of the driving member 320 is connected to the driving wheel 331 of the gear pair, and a connecting rod 333 is coaxially arranged on the driven wheel 332 of the gear pair. The connecting rod 333 is connected to the transmission member 330 via the air inlet pipe 200.

[0067] The transmission member 330 is configured as a gear pair, and the stable rotation characteristic of the gear pair can be utilized to ensure that the rotating member 310 stably stops at the first position, the second position, the third position and any transition position during the rotation process.

[0068] In addition, a transmission gear pair can be used to control the required rotation speed of the rotating member 310 by adjusting the transmission ratio between the driving wheel 331 and the driven wheel 332 according to the actual rotation speed of the output end of the driving member 320, so that the operation of the opening and closing component 300 is more stable and reliable.

[0069] When setting up the specific Figure 2 and Figure 3As shown, the accommodating cavity 231 is a spherical accommodating cavity 231, and the rotating member 310 is a spherical shell adapted to the spherical accommodating cavity 231. Such a configuration can make the rotating member 310 rotate more smoothly in the accommodating cavity 231, and can make the volume of the ventilation cavity 314 larger, which is convenient for increasing the air output of the fresh air component 100. In other embodiments, the accommodating cavity 231 can also be set as a cylindrical accommodating cavity 231, and a shell that is also cylindrical is set as the rotating member 310 to adapt to the accommodating cavity 231. The present application does not limit the structure of the accommodating cavity 231 and the rotating member 310, as long as they can rotate around their axis and form a circular surface.

[0070] In addition, the rotating member 310 may also be configured as a baffle member, which is not limited in the present application.

[0071] In some embodiments, reference Figure 2 and Figure 3 As shown, the air inlet duct 200 includes an indoor air inlet section 210, an outdoor air inlet section 220 and a junction section 230. The indoor air inlet section 210 is used to communicate with the indoor environment, and the outdoor air inlet section 220 is used to communicate with the outdoor environment. The indoor air inlet section 210 and the outdoor air inlet section 220 are respectively connected to the junction section 230, and the accommodating cavity 231 is located in the junction section 230. Such an arrangement can make the structure of the air inlet duct 200 relatively simple and compact, and is easy to implement.

[0072] The indoor air inlet section 210, the outdoor air inlet section 220 and the intersection section 230 are arranged in sequence, and specifically can be coaxially connected once along the same extension direction, or a certain angle can be provided between the indoor air inlet section 210 and the outdoor air inlet section 220, and the present application does not impose any limitation on this.

[0073] Furthermore, the air inlet duct 200 further includes a connecting pipe 500, and the accommodating chamber 231 and the air inlet 120 are connected via the connecting pipe 500. The extension directions of the indoor air inlet section 210, the outdoor air inlet section 220 and the connecting pipe 500 are respectively located in the same plane, and the rotation axis of the rotating member 310 is perpendicular to the plane. Such an arrangement can make the connection between the air inlet duct 200 and the fresh air assembly 100 more convenient, and facilitate the rotating member 310 to simultaneously control the relative positions between the first connecting port 311, the second connecting port 312 and the third connecting port 313 and the air inlet duct 200 around a single rotation axis.

[0074] In a specific implementation, the indoor air inlet section 210, the outdoor air inlet section 220, the intersection section 230 and the connecting pipe 500 can be an integrated part, or the indoor air inlet section 210, the outdoor air inlet section 220, the intersection section 230 and the connecting pipe 500 can be set as separate pipe sections and detachably connected to each other. This application does not impose any restrictions on this.

[0075] In addition, an embodiment of the present application further provides an air conditioner, comprising an air conditioner body 400 and a fresh air system in any of the above embodiments, wherein the fresh air system is disposed on the air conditioner body 400 .

[0076] Among them, the fresh air system has been described in detail in the above embodiments and will not be repeated here.

[0077] The present application provides an air conditioner, which is provided with a fresh air system.
