DETAILED DESCRIPTION

[0043] The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, for the purpose of explanation, and are not to be understood as a limitation of the present application.

[0044] The following description refers to the accompanying drawings. Figures 1-22 The air conditioner 100 according to the embodiments of the present application is described below, which is provided with the purification component 2 in the air flow passage 11, capable of purifying the air flow through the air flow passage 11, for example, capable of removing formaldehyde, removing odor, etc. from the indoor air through the purification component 2, and then the purified air enters the indoor, or capable of removing dust, removing odor, etc. from the outdoor air through the purification component 2, and then the purified air enters the indoor.

[0045] Therefore, by providing the purification component 2 in the air flow passage 11, the purification of the indoor air can be achieved, the quality of the indoor air is improved, the health needs of the user are met, and the use comfort of the user is improved.

[0046] Further, the air conditioner 100 is further provided with the mode switching assembly 7, and the mode switching assembly 7 has a simple structure and is easy to set, so that the movement mechanism is less, the assembly difficulty is reduced, and the production efficiency is improved. At the same time, by providing the first air flow port 75 and the second air flow port 76 on the switching structure 72, the switching between different air outlet modes of the air conditioner 100 can be realized by changing the communication relationship between the first air flow port 75 and / or the second air flow port 76 and the inner air inlet 4, the inner air outlet 5, and the outer air flow port 61, and the switching process is simple, thereby meeting different use needs of the user.

[0047] It should be noted that, as Figures 1-3As shown, the air conditioner 100 is provided with a panel component 81 and an outer box bottom plate 82, the panel component 81 is installed on the front side of the outer box bottom plate 82 component to define an internal space of the air conditioner 100 with the outer box bottom plate 82 component, and the airflow passage 11 is arranged in the internal space.

[0048] As shown, Figures 1-22 According to the air conditioner 100 of the embodiment of the present application, the air conditioner 100 comprises a shell 1 and a mode switching assembly 7.

[0049] As shown, Figure 2 The shell 1 has an airflow passage 11, that is, the airflow flows in the air conditioner 100 through the airflow passage 11, for example, the air conditioner 100 can transport outdoor air to indoor through the airflow passage 11, or the air conditioner 100 can transport indoor air to outdoor through the airflow passage 11, or the air conditioner 100 can circulate indoor air and then transport the indoor air to indoor again through the airflow passage 11.

[0050] Preferably, as shown, Figure 2 and Figure 3 The shell 1 of the air conditioner 100 is provided with an airflow pipe 6, and the airflow pipe 6 communicates with the airflow passage 11, and it should be noted that the airflow pipe 6 is arranged on the side of the air conditioner 100 close to the outdoor environment and extends away from the air conditioner 100.

[0051] Therefore, the outdoor air can enter the air conditioner 100 through the airflow pipe 6 and then be blown to indoor through the airflow passage 11, thereby completing the function of the air conditioner 100 to intake air to indoor, of course, the indoor air can enter the air conditioner 100 through the airflow passage 11 and then be blown to outdoor through the airflow pipe 6, thereby completing the function of the air conditioner 100 to ventilate indoor, which facilitates the purification of indoor air, improves the quality of indoor air, meets the health needs of users, and improves the use comfort of users.

[0052] The airflow passage 11 is provided with a purification component 2 and an airflow driving component 3, and the shell 1 is provided with an inner air inlet 4, an inner air outlet 5, and an outer airflow port 61, which all communicate with the airflow passage 11.

[0053] It can be understood that the inner air inlet 4, the inner air outlet 5, and the outer airflow port 61 of the shell 1 all communicate with the airflow passage 11, preferably, the outer airflow port 61 is arranged on the side of the air conditioner 100 facing outdoor and communicates with the airflow pipe 6, so as to facilitate the outdoor airflow to enter the airflow passage 11 through the outer airflow port 61, the inner air outlet 5 is arranged on the side of the air conditioner 100 facing indoor and is located in the upper region of the shell 1, so as to facilitate the air conditioner 100 to blow air to indoor, and the inner air inlet 4 can also be arranged on the side of the air conditioner 100 facing indoor and is located in the lower region of the shell 1, so as to facilitate the indoor air to enter the air conditioner 100 through the inner air inlet 4.

[0054] Preferably, the inner air outlet 5 and the inner air inlet 4 can be provided with two, and the two inner air outlets 5 are symmetrically distributed on the left and right sides of the air conditioner 100, and the two inner air inlets 4 are also symmetrically distributed on the left and right sides of the air conditioner 100.

[0055] Therefore, it is convenient to increase the rate of the air conditioner 100 blowing towards the indoor, and the rate of the indoor air entering the air conditioner 100 through the inner air inlet 4. Further, in the present application, any two of the inner air inlet 4, the inner air outlet 5 and the outer airflow port 61 are communicated through the airflow channel 11 to realize different working modes of the air conditioner 100.

[0056] For example, the inner air inlet 4 and the inner air outlet 5 are communicated through the airflow channel 11, at this time the air conditioner 100 is in the indoor circulation mode, that is, the indoor air enters the airflow channel 11 through the inner air inlet 4, and then is discharged into the indoor through the inner air outlet 5, thereby completing the circulation of the indoor air. It should be noted that the indoor air will pass through the purification component 2 when entering the airflow channel 11, thereby the indoor air can be purified by the purification component 2, thereby improving the quality of the indoor air, meeting the health needs of the user, and improving the use comfort of the user.

[0057] Alternatively, the inner air inlet 4 and the outer airflow port 61 are communicated through the airflow channel 11, at this time the air conditioner 100 is in the exhaust mode, that is, the indoor air enters the airflow channel 11 through the inner air inlet 4, and then is discharged to the outdoor through the outer airflow port 61, thereby completing the discharge of the indoor air, and further facilitating the discharge of the indoor air to the outdoor.

[0058] Further alternatively, the inner air outlet 5 and the outer airflow port 61 are communicated through the airflow channel 11, at this time the air conditioner 100 is in the fresh air mode, that is, the outdoor air enters the airflow channel 11 through the outer airflow port 61, and then is discharged into the indoor through the inner air outlet 5, thereby introducing fresh air into the indoor. It should be noted that the outdoor air will pass through the purification component 2 when entering the airflow channel 11, thereby the part of the air can be purified by the purification component 2, thereby improving the quality of the air entering the indoor, meeting the health needs of the user, and improving the use comfort of the user.

[0059] Of course, the inner air inlet 4, the inner air outlet 5 and the outer airflow port 61 can also not be communicated with the airflow channel 11, at this time the air conditioner 100 is in the off mode, that is, the air conditioner 100 does not work, thereby preventing the outdoor air from being forcibly poured into the indoor, and being beneficial to improve the use comfort of the user.

[0060] The purifying component 2 is arranged at the middle portion of the airflow channel 11, so that the outdoor or indoor airflow entering the airflow channel 11 of the air conditioner 100 can pass through the purifying component 2, thereby the air conditioner 100 has the function of purifying the air by arranging the purifying component 2 in the airflow channel 11, and the airflow driving member 3 can be a centrifugal fan, and the airflow driving member 3 can be arranged in the casing 1 and faces the outdoor airflow port 61 and the indoor air inlet 4. Thus, the airflow entering or blowing out of the air conditioner 100 can be enhanced by arranging the airflow driving member 3, thereby meeting the use requirements of the user.

[0061] Further, as shown in Figure 2 and Figure 8 The mode switching assembly 7 is arranged at the end of the airflow pipe 6 connected with the casing 1.

[0062] Specifically, the mode switching assembly 7 comprises a driving member 71 and a switching structure 72, preferably the driving member 71 can be a driving motor, and the driving member 71 is arranged outside the casing 1, and the switching structure 72 is arranged on the casing 1, so as to control the switching structure 72 by the driving member 71, and the structure is simple, which is easy to reduce the difficulty of assembly and disassembly, thereby reducing the production cost.

[0063] The switching structure 72 has a first airflow port 75 and a second airflow port 76, and the driving member 71 is used to drive the switching structure 72 to move, so as to make the outdoor airflow port 61 communicate with the indoor air inlet 4 through the first airflow port 75, or communicate with the indoor air outlet 5 through the second airflow port 76, and be disconnected with the airflow channel 11.

[0064] It can be understood that in the actual working process of the air conditioner 100, the driving member 71 is used to drive the switching structure 72 to rotate, so as to change the communication relationship between the first airflow port 75 and / or the second airflow port 76 and the indoor air inlet 4, the indoor air outlet 5 and the outdoor airflow port 61, for example, the driving member 71 drives the switching structure 72 to rotate, so that the outdoor airflow port 61 communicates with the indoor air inlet 4 through the first airflow port 75, or the outdoor airflow port 61 communicates with the indoor air outlet 5 through the second airflow port 76, or the outdoor airflow port 61 is disconnected with the airflow channel 11 through the second airflow port 76. Thus, by arranging the mode switching assembly 7, the flow direction of the indoor airflow of the air conditioner 100 can be realized, and the switching process is simple, which is easy to meet the different use requirements of the user.

[0065] The air conditioner 100 according to the embodiment of the present application can realize that the outer air flow port 61 is communicated with the inner air inlet 4 through the first air flow port 75 or the outer air flow port 61 is communicated with the inner air outlet 5 through the second air flow port 76 by the movement of the switching structure 72, so as to change the air flow direction of the air conditioner 100, so that the air flow can be purified by the purification component 2, thereby improving the indoor air quality, and the structure of the mode switching assembly 7 of the air conditioner 100 is simplified, the production cost is reduced, and the user experience is improved. At the same time, the movement of the switching structure 72 can disconnect the outer air flow port 61 and the air flow channel 11, so as to prevent the outdoor air from being forcibly poured into the indoor, and improve the user's use comfort.

[0066] In some embodiments, as shown in Figure 9 The switching structure 72 includes a rotating drum 721 and a closure 722.

[0067] The rotating drum 721 is rotatably supported on the closure 722, and the rotating drum 721 has a port communicated with the outer air flow port 61, and the first air flow port 75 and the second air flow port 76 are both arranged on the rotating drum 721 and communicated with the port. That is, one end of the rotating drum 721 is open and communicated with the outer air flow port 61, and the first air flow port 75 and the second air flow port 76 are further arranged on the rotating drum 721, and both the first air flow port 75 and the second air flow port 76 can be communicated with the port, so that the rotating drum 721 can play a role in ensuring the air flow mobility in the air flow channel 11 through such a setting.

[0068] The driving member 71 is used to drive the rotating drum 721 to rotate relative to the closure 722, so as to selectively communicate or disconnect the first air flow port 75 and the second air flow port 76 with the air flow channel 11. It can be understood that the closure 722 can be fixedly installed on the cabinet 1, and the driving member 71 drives the rotating drum 721 to rotate relative to the closure 722, changes the relative position relationship between the rotating drum 721 and the closure 722, so that the closure 722 shields the first air flow port 75 and / or the second air flow port 76.

[0069] Therefore, the closure 722 shields the first air flow port 75 and / or the second air flow port 76 through the rotating drum 721, so that the air flow can flow out through the first air flow port 75 or the second air flow port 76, thereby changing the working mode of the air conditioner 100, meeting the different use requirements of the user, improving the user experience, of course, the closure 722 can also shield the first air flow port 75 and the second air flow port 76 at the same time, so as to block the flow of the air flow in the air flow channel 11, thereby preventing the outdoor air from being forcibly poured into the indoor, and improving the user's use comfort.

[0070] Further, as shown in Figure 9As shown, the closure 722 has a semi-cylindrical supporting cavity 7221 which is radially and axially open, and the rotating drum 721 is rotatably supported at the supporting cavity 7221. Preferably, the rotating drum 721 can be configured as a cylinder, and the rotating drum 721 can abut against the inner wall of the supporting cavity 7221.

[0071] It can be understood that the inner wall of the supporting cavity 7221 is formed with an arc-shaped abutting surface, and the rotating drum 721 can be configured as a cylinder, so that when the rotating drum 721 is installed in the supporting cavity 7221, the contact area between the rotating drum 721 and the closure 722 can be increased, thereby enhancing the structural stability of the rotating drum 721, and the friction between the rotating drum 721 and the closure 722 can be reduced, thereby reducing the energy consumption of the rotating drum 721 when rotating, thereby facilitating the reduction of the energy consumption of the air conditioner 100 when switching the working mode, and reducing the use cost of the air conditioner 100.

[0072] The port of the rotating drum 721 is arranged at the first end 7211 of the rotating drum 721 and is axially open. That is, the first end 7211 of the rotating drum 721 is an open port, and the first end 7211 of the rotating drum 721 is in communication with the outer airflow port 61 through the airflow pipe 6, so that the airflow can be blown out from the outer airflow port 61 through the rotating drum 721, or the airflow can enter the rotating drum 721 through the outer airflow port 61.

[0073] Specifically, the first airflow port 75 is arranged at the second end 7212 of the rotating drum 721 and is axially and radially open, and the second airflow port 76 is arranged at the outer peripheral wall of the rotating drum 721 and is radially open. It can be understood that the first airflow port 75 includes a radial opening and an axial opening, and the radial opening and the second airflow port 76 are on the same side of the axial direction of the rotating drum 721, and the axial opening is arranged opposite to the port.

[0074] Therefore, by arranging the first airflow port 75 and the second airflow port 76, the flow direction of the airflow in the air conditioner 100 can be changed, and the closure 722 blocks the first airflow port 75 and / or the second airflow port 76, so that the airflow can pass through the first airflow port 75 or the second airflow port 76, thereby changing the working mode of the air conditioner 100, meeting the different use requirements of the user, improving the use experience of the user, and of course, the closure 722 can also block the first airflow port 75 and the second airflow port 76 at the same time, so as to block the flow of the airflow in the airflow passage 11, thereby preventing the outdoor air from being forcibly filled into the indoor, and facilitating the improvement of the use comfort of the user.

[0075] Further, as shown in FIG. 6, the air conditioner 100 further comprises a second airflow port 76 arranged at the outer peripheral wall of the rotating drum 721 and radially open. Figure 9As shown, the first air flow port 75 and the second air flow port 76 are both located at the same axial side of the drum 721, and the first air flow port 75 and the second air flow port 76 are staggered in the axial direction of the drum 721. Thus, the closure 722 can shield one of the first air flow port 75 and the second air flow port 76, and of course, the closure 722 can shield the first air flow port 75 and the second air flow port 76 at the same time, so as to facilitate the air conditioner 100 to realize different working modes.

[0076] In some embodiments, the first air flow port 75 and the second air flow port 76 have an opening angle in the circumferential direction of the drum 721 less than or equal to 45°. It can be understood that the opening angle of the second air flow port 76 and the radial opening in the circumferential direction of the drum 721 is less than or equal to 45°.

[0077] For example, the opening angle of the radial opening and the second air flow port 76 in the circumferential direction of the drum 721 can be 20°, or the opening angle of the radial opening and the second air flow port 76 in the circumferential direction of the drum 721 can be 30°, or the opening angle of the radial opening and the second air flow port 76 in the circumferential direction of the drum 721 can be 40°. It should be noted that the opening angle of the axial opening in the circumferential direction of the drum 721 is the same as the opening angle of the radial opening in the circumferential direction of the drum 721.

[0078] It can be understood that the opening angle of the radial opening and the second air flow port 76 in the circumferential direction of the drum 721 can be the same, and of course, the opening angle of the radial opening and the second air flow port 76 in the circumferential direction of the drum 721 can be different, which is not limited herein.

[0079] Thus, when the opening angle of the radial opening and the second air flow port 76 in the circumferential direction of the drum 721 meets the above requirements, the inner wall of the closure 722 can sufficiently shield the radial opening and / or the second air flow port 76, so as to ensure the air tightness of the drum 721, and facilitate the closure 722 to block the flow of the airflow in the airflow passage 11 when the closure 722 shields the first air flow port 75 and the second air flow port 76 at the same time, thereby preventing the outdoor air from being forcibly filled into the indoor air through the outer air flow port 61, and improving the user's use comfort.

[0080] In some embodiments, the airflow driving member 3 is configured as a centrifugal fan, the inner air inlet 4 is located in the radial direction of the centrifugal fan, and the drum 721 is located in the axial direction of the centrifugal fan. That is, the inner air inlet 4 is arranged opposite to the centrifugal fan in the radial direction of the centrifugal fan, and the drum 721 is arranged opposite to the centrifugal fan in the axial direction of the centrifugal fan.

[0081] It can be understood that the two inner air inlets 4 are symmetrically arranged in the radial direction of the centrifugal fan, and the rotating drum 721 is arranged in the axial direction of the centrifugal fan. Therefore, the design and arrangement of the inner air outlet 5 and the rotating drum 721 are facilitated, and the design and arrangement difficulty is reduced. At the same time, when the indoor air enters the airflow passage 11 through the inner air inlet 4, the airflow at the two inner air inlets 4 can be integrated by the centrifugal fan, so as to facilitate the uniform flow of the airflow, and improve the flow rate of the airflow.

[0082] Further, the rotating drum 721 is arranged in the axial direction of the centrifugal fan, so that under the action of the centrifugal fan, the outdoor air can enter the airflow passage 11 through the outer airflow port 61 more quickly, improve the flowability of the airflow, and improve the flow rate of the airflow, thereby increasing the working efficiency of the air conditioner 100.

[0083] In some embodiments, as shown in Figure 9 The switching structure 72 further includes a mounting bracket 73 and a transmission member 74.

[0084] The rotating drum 721 is rotatably mounted on the mounting bracket 73, and the driving member 71 is mounted on the mounting bracket 73 and is power-connected with the rotating drum 721 through the transmission member 74. It can be understood that the mounting bracket 73 is mounted on the shell 1, and the mounting bracket 73 is provided with a mounting hole, so that the airflow pipe 6 can pass through the mounting hole and be connected with the airflow passage 11 of the air conditioner 100.

[0085] Preferably, the rotating drum 721 and the driving member 71 are arranged on opposite sides of the mounting bracket 73, and the transmission member 74 is mounted between the driving member 71 and the mounting bracket 73, that is, the rotating drum 721 can be mounted in the shell 1, and the driving member 71 can be mounted outside the shell 1.

[0086] The transmission member 74 can pass through the mounting bracket 73 to be fixedly connected with the rotating drum 721, so that the rotating drum 721 is not directly visible outside the air conditioner 100, and the driving member 71 is arranged outside the shell 1, facilitating the user to control and maintain the driving member 71, and reducing the maintenance difficulty of the driving member 71.

[0087] Therefore, when the driving member 71 drives the transmission member 74, the transmission member 74 can drive the rotating drum 721 to rotate synchronously, thereby reducing the switching difficulty of the switching structure 72, reducing the arrangement of the movement structure, simplifying the structure of the mode switching assembly 7, and reducing the production cost.

[0088] In some embodiments, as shown in Figure 10 The transmission member 74 can be configured as a set of driven gears 742, and the transmission member 74 includes a driving gear 741 and the driven gears 742.

[0089] The transmission member 74 can be configured as a set of driven gears 742, and the transmission member 74 includes a driving gear 741 and the driven gears 742. Figure 10As shown, the driving gear 741 is sleeved on the output shaft 711 of the driving member 71, the output shaft 711 of the driving member 71 penetrates the driving gear 741 and extends into the positioning groove of the mounting bracket 73, so as to enhance the structural stability of the driving member 71, the driven gear 742 is arranged on the side of the mounting bracket 73 close to the driving member 71, and the driven gear 742 is connected in meshing connection with the driving gear 741. Meanwhile, the driven gear 742 is provided with a rotating shaft, and the rotating shaft penetrates the mounting bracket 73 to be fixedly connected with the rotating drum 721.

[0090] That is, as Figure 10 shown, when the driving member 71 rotates the driving switching structure 72, the working process is as follows: the output shaft 711 of the driving member 71 rotates to drive the driving gear 741 to rotate, at this time, the driving gear 741 drives the driven gear 742 from the driving member 71, at this time, the driven gear 742 drives the rotating drum 721 to rotate synchronously through the rotating shaft, so that the closing member 722 shields the first air flow port 75 and / or the second air flow port 76, so that the air flow can flow out through the first air flow port 75 or the second air flow port 76.

[0091] Therefore, it is convenient to change the working mode of the air conditioner 100, meet the different use requirements of the user, improve the use experience of the user, of course, the closing member 722 can also shield the first air flow port 75 and the second air flow port 76 at the same time, can block the flow of the air flow in the air flow channel 11, so as to prevent the outdoor air from being forced to flow into the indoor, which is beneficial to improve the use comfort of the user.

[0092] It should be noted that, as Figure 10 shown, the radial dimension of the driven gear 742 is greater than the radial dimension of the driving gear 741, so as to increase the transmission ratio, that is, the driving member 71 can drive the rotating drum 721 through smaller driving force, which is convenient to reduce the energy consumption of the mode switching assembly 7 and reduce the use cost of the air conditioner 100.

[0093] In some embodiments, as Figure 10 shown, the driving member 71 is also provided with two connecting plates 712, and the two connecting plates 712 are both provided with connecting holes, so that when the driving member 71 is installed on the mounting bracket 73, the connecting holes can be penetrated by bolts to be threadedly connected with the mounting bracket 73, further enhancing the structural stability of the driving member 71.

[0094] In some embodiments, the air conditioner 100 further comprises a control module (not shown in the figure).

[0095] As Figures 3-6As shown, the casing 1 is further provided with a first valve 41 for opening the inner air inlet 4 and a second valve 51 for opening the inner air outlet 5. That is, the first valve 41 is arranged at the inner air inlet 4, the second valve 51 is arranged at the inner air outlet 5, and the inner air inlet 4 and the inner air outlet 5 can be selectively opened by rotating the first valve 41 and the second valve 51.

[0096] In some embodiments, as shown in

[0097] Further, the driving structure corresponding to the first valve 41 and the second valve 51, the driving member 71, and the airflow driving member 3 are electrically connected with the control module. The driving structure is used to drive the corresponding first valve 41 and second valve 51 to open or close the inner air inlet 4 and the inner air outlet 5.

[0098] That is, the control module can control the first valve 41 to open or close the inner air inlet 4, control the second valve 51 to open or close the inner air outlet 5, control the working mode of the airflow driving member 3, and control the driving member 71 to drive the switching structure 72 to rotate. Thus, by integrating the control of multiple structures on one control module, the internal structure size of the air conditioner 100 can be saved, the miniaturization and lightweight design of the air conditioner 100 can be realized, and the working mode of the air conditioner 100 can be changed by the control module, thereby meeting different use requirements of users and improving the use comfort of users.

[0099] In some embodiments, as shown in Figures 11-13 the air conditioner 100 has a fresh air mode, and in the fresh air mode, the control module is configured to control the airflow driving member 3 to be turned on, the first valve 41 to open the inner air outlet 5, the second valve 51 to close the inner air inlet 4, and the driving member 71 to drive the switching structure 72 to communicate the outer airflow port 61 with the inner air outlet 5 through the first airflow port 75.

[0100] As can be understood, when the air conditioner 100 is in the fresh air mode, as shown in Figure 12 and Figure 13 the first valve 41 opens the inner air outlet 5, and the second valve 51 closes the inner air inlet 4. At this time, the control module controls the driving member 71 to rotate, as shown in Figure 11 so that the closure 722 shields the second airflow port 76, and the closure 722 does not shield the first airflow port 75.

[0101] Thus, under the action of the air flow driving member 3, outdoor air can enter the air flow pipe 6 through the outdoor air flow port 61, and then the air enters the air flow channel 11 through the port of the rotating drum 721 and the first air flow port 75 in turn, and is purified by the purification component 2, and is then blown to the indoor by the indoor air outlet 5, so that the outdoor fresh air is blown to the indoor, thereby facilitating the improvement of the air quality in the indoor, and meeting the health needs of the user and improving the use comfort of the user.

[0102] In some embodiments, as shown in Figures 14-16 , the air conditioner 100 has an exhaust mode, and in the exhaust mode, the control module is configured to: control the air flow driving member 3 to be turned on, control the first valve 41 to close the indoor air outlet 5, control the second valve 51 to open the indoor air inlet 4, and control the driving member 71 to drive the switching structure 72 to communicate the outdoor air flow port 61 with the indoor air inlet 4 through the second air flow port 76.

[0103] It can be understood that when the air conditioner 100 is in the exhaust mode, as shown in Figure 15 and Figure 16 , the first valve 41 closes the indoor air outlet 5, and the second valve 51 opens the indoor air inlet 4, at this time, as shown in Figure 14 , the control module controls the driving member 71 to rotate, so that the blocking member 722 blocks the first air flow port 75, and the blocking member 722 does not block the second air flow port 76.

[0104] Thus, under the action of the air flow driving member 3, indoor air can enter the rotating drum 721 through the indoor air inlet 4, and then the air enters the air flow pipe 6 through the second air flow port 76 of the rotating drum 721 and the port in turn, and is then blown to the outdoor through the outdoor air flow port 61, so that the indoor air is blown to the outdoor, thereby facilitating the exhaust of the indoor air, meeting the health needs of the user, and improving the use comfort of the user.

[0105] In some embodiments, as shown in Figures 17-22 , the air conditioner 100 has an indoor circulation mode and a shutdown mode;

[0106] As shown in Figures 17-19 , in the indoor circulation mode, the control module is configured to: control the air flow driving member 3 to be turned on, control the first valve 41 to open the indoor air outlet 5, control the second valve 51 to open the indoor air inlet 4, and control the driving member 71 to drive the switching structure 72 to disconnect the outdoor air flow port 61 from the air flow channel 11.

[0107] It can be understood that when the air conditioner 100 is in the indoor circulation mode, as shown in Figure 18 and Figure 19 , the first valve 41 opens the indoor air outlet 5, and the second valve 51 opens the indoor air inlet 4, at this time, as shown in Figure 14As shown, the control module controls the driving member 71 to rotate, so that the closing member 722 shields the first air flow port 75, and at the same time, the closing member 722 shields the second air flow port 76, at this time, the outdoor air flow port 61 is not communicated with the air flow channel 11.

[0108] Therefore, under the action of the air flow driving member 3, the indoor air can enter the air flow channel 11 through the indoor air inlet 4, and then pass through the purification component 2, which can perform formaldehyde removal, odor removal and other operations on the part of the air, and then be blown to the indoor again by the indoor air outlet 5, thereby realizing the purification of indoor air, meeting the health needs of users, and preventing outdoor air from entering the indoor, that is, preventing outdoor air from being forcibly poured into the indoor, thereby improving the use comfort of users.

[0109] As shown in the figure, Figures 20-22 in the shutdown mode, the control module is configured to control the air flow driving member 3 to be closed, the first valve 41 to close the indoor air outlet 5, the second valve 51 to close the indoor air inlet 4, and the driving member 71 to drive the switching structure 72 to disconnect the outdoor air flow port 61 from the air flow channel 11.

[0110] It can be understood that when the air conditioner 100 is in the shutdown mode, the control module controls the air flow driving member 3 to be closed, and as shown in Figure 21 and Figure 22 , the first valve 41 closes the indoor air outlet 5, and the second valve 51 closes the indoor air inlet 4, at this time, as shown in Figure 20 , the control module controls the driving member 71 to rotate, so that the closing member 722 shields the first air flow port 75, and at the same time, the closing member 722 shields the second air flow port 76, at this time, the outdoor air flow port 61 is not communicated with the air flow channel 11, at this time, the air conditioner 100 is in the shutdown or standby state, that is, the air conditioner 100 is temporarily not working.

[0111] Further, by disconnecting the outdoor air flow port 61 from the air flow channel 11 through the switching structure 72, it is convenient to prevent outdoor air from being forcibly poured into the indoor, thereby improving the use comfort of users.

[0112] Therefore, the air conditioner 100 of the present application can realize that the outdoor air flow port 61 is communicated with the indoor air inlet 4 through the first air flow port 75, or the outdoor air flow port 61 is communicated with the indoor air outlet 5 through the second air flow port 76 through the movement of the switching structure 72, thereby facilitating the change of the air flow direction of the air conditioner 100, and further realizing different working modes of the air conditioner, at the same time, it is convenient to improve the indoor air quality, and it is convenient to simplify the structure of the mode switching assembly 7 of the air conditioner 100, reduce the production cost, improve the use experience of users, and at the same time, the outdoor air flow port 61 can be disconnected from the air flow channel 11 through the movement of the switching structure 72, thereby preventing outdoor air from being forcibly poured into the indoor, thereby improving the use comfort of users.
