[0029] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which like numerals indicate like elements or elements having the same or similar function. The embodiments described below are examples only, and are not to be construed as limiting the present application.

[0030] Reference is made below to Figures 1-7The air conditioner 100 according to the embodiment of the present application has a new air mode, a purification mode and an exhaust air mode, can not only be used for introducing new air from the outdoor space into the indoor space, but also can purify the air in the indoor space and exhaust the gas with heavy odor in the indoor space to the outdoor space, thereby having the functions of new air, purification and exhaust air, simple structure, rich functions, high practicability and high work efficiency.

[0031] As shown in Figure 1 The air conditioner 100 according to the embodiment of the present application comprises a fixed seat 1 and a volute assembly 2.

[0032] The fixed seat 1 has a first air inlet flow channel 111 and a second air inlet flow channel 121. The first air inlet flow channel 111 is provided with a first air inlet 112 for realizing the communication between the air conditioner 100 and the outdoor space, and in the actual working process, the airflow in the outdoor space can be introduced into the first air inlet flow channel 111 through the first air inlet 112. The second air inlet flow channel 121 is provided with a second air inlet for communicating with the indoor space, and in the actual working process, the airflow in the indoor space can be introduced into the second air inlet flow channel 121 through the second air inlet, so that the air conditioner 100 can process the airflow in the indoor space and also can process the airflow in the outdoor space.

[0033] The fixed seat is provided with a mounting surface, and the volute assembly 2 is mounted on the mounting surface. The volute assembly 2 has a wind wheel cavity 27 and an exhaust cavity 28. The first air inlet flow channel 111 and the second air inlet flow channel 121 are both in communication with the wind wheel cavity 27. It should be noted that the wind wheel cavity 27 is provided with a wind wheel assembly 23, which comprises a wind wheel and a power source for driving the wind wheel. The power source can be a driving motor. The motor shaft of the driving motor is connected with the fixed shaft of the wind wheel, so that the driving motor can drive the wind wheel to rotate in the wind wheel cavity 27. In this way, when the wind wheel rotates, the airflow in the wind wheel cavity 27 can be driven to flow, and under the action of the air pressure of the airflow flowing in the wind wheel cavity 27, the airflow in the first air inlet flow channel 111 and the second air inlet flow channel 121 can be continuously driven to flow, which is beneficial to more airflow entering the first air inlet flow channel 111, the second air inlet flow channel 121 and the wind wheel cavity 27.

[0034] The wind wheel cavity 27 is in selective communication with the exhaust cavity 28, and the wind wheel cavity 27 is provided with a first air outlet 24 for communication with an indoor space, and the exhaust cavity 28 is provided with a second air outlet 25 for communication with an outdoor space. That is, the exhaust cavity 28 can be selected to be in communication with the wind wheel cavity 27, or not in communication with the wind wheel cavity 27. When the exhaust cavity 28 is in communication with the wind wheel cavity 27, the airflow accelerated by the wind wheel assembly 23 can enter the exhaust cavity 28, and can be discharged to the outdoor space through the second air outlet 25 of the exhaust cavity 28; when the exhaust cavity 28 is not in communication with the wind wheel cavity 27, the airflow accelerated by the wind wheel assembly 23 can be directly discharged to the indoor space through the first air outlet 24, and at this time there is no obvious airflow flowing in the exhaust cavity 28.

[0035] The first air inlet flow channel 111 and the second air inlet flow channel 121 are provided with filter elements, and it can be understood that the first air inlet flow channel 111 and the second air inlet flow channel 121 are used to introduce indoor airflow or outdoor airflow into the wind wheel cavity 27. In this way, the filter elements arranged in the first air inlet flow channel 111 and the second air inlet flow channel 121 can not only realize filtration of indoor airflow, but also realize filtration of outdoor airflow, thereby facilitating air purification.

[0036] In the present application, by arranging the fixing seat 1 and the volute assembly 2, and installing the fixing seat 1 and the volute assembly 2 to form the first air inlet flow channel 111, the second air inlet flow channel 121, the wind wheel cavity 27 and the exhaust cavity 28, the effects of air inlet, acceleration and air exhaust can be realized, and the internal structure of the air conditioner 100 is greatly simplified, which is conducive to realizing lightweight design of the air conditioner 100.

[0037] The first air inlet 112 is provided with a first valve 41, and the first valve 41 is configured to be movable at the first air inlet 112. That is, by driving the first valve 41 to move at the first air inlet 112, the first valve 41 can be used to selectively open and close the first air inlet 112, so that the first air inlet 112 is in selective communication with the outdoor space. For example, the first valve 41 can be driven to open the first air inlet 112, so that outdoor air can enter the first air inlet flow channel 111; or the first valve 41 can be driven to close the first air inlet 112, so as to hinder the communication between the outdoor space and the first air inlet flow channel 111.

[0038] and the second air inlet is provided with a second valve 42, which is movable at the second air inlet, that is, the second valve 42 is used for selectively opening and closing the second air inlet to selectively communicate the indoor space with the second air inlet by driving the second valve 42 to move at the second air inlet, for example, the second valve 42 is driven to open the second air inlet so that the indoor air can enter the second air inlet flow channel 121, or the second valve 42 is driven to close the second air inlet to hinder the communication between the indoor space and the first air inlet flow channel 111.

[0039] and the first air outlet 24 is provided with a third valve 43, which is movable at the first air outlet 24, that is, the third valve 43 is used for selectively opening and closing the first air outlet 24 to selectively communicate the indoor space with the first air outlet 24 by driving the third valve 43 to move at the first air outlet 24, for example, the third valve 43 is driven to open the first air outlet 24 so that the airflow in the impeller cavity 27 can be discharged to the indoor space, or the third valve 43 is driven to close the first air outlet 24 to hinder the communication between the indoor space and the first air outlet 24.

[0040] and the second air outlet 25 is provided with a fourth valve 44, which is movable at the second air outlet 25, that is, the fourth valve 44 is used for selectively opening and closing the second air outlet 25 to selectively communicate the outdoor space with the second air outlet 25 by driving the fourth valve 44 to move at the second air outlet 25, for example, the fourth valve 44 is driven to open the second air outlet 25 so that the airflow in the exhaust cavity 28 can be discharged to the outdoor space, or the fourth valve 44 is driven to close the second air outlet 25 to hinder the communication between the outdoor space and the second air outlet 25.

[0041] In this way, the states of the valves at each chamber and each air outlet can be switched to enable the air conditioner 100 to realize different working modes. Among them, the air conditioner 100 in the present application can realize a fresh air mode, a purification mode and an exhaust mode.

[0042] Specifically, in the fresh air mode, the first air inlet 112 is in an open state, i.e., the first air inlet 112 communicates with the outdoor space, the first air outlet 24 communicates with the indoor space, and the second air inlet and the second air outlet 25 are both in a closed state, and the impeller cavity 27 and the exhaust cavity 28 are in a disconnected state. In this way, the fresh air flow in the outdoor space can enter the first air inlet 112 into the first air inlet flow channel 111, and be filtered by the filter, realizing the purification effect of the external fresh air flow, and further entering the impeller cavity 27 under the action of the impeller assembly 23, and being accelerated in the impeller cavity 27 and then being discharged to the indoor space through the first air outlet 24. Thus, the fresh air in the outdoor space can be introduced into the indoor space through the air conditioner 100, and thus the air conditioner 100 has a fresh air mode.

[0043] In the purification mode, the second air inlet is in an open state, i.e., the second air inlet communicates with the indoor space, the first air outlet 24 communicates with the indoor space, and the first air inlet 112 and the second air outlet 25 are both in a closed state, and the impeller cavity 27 and the exhaust cavity 28 are in a disconnected state. In this way, the air flow in the indoor space can enter the second air inlet into the second air inlet flow channel 121, and be filtered by the filter to remove impurities such as dust and cooking fumes in the indoor air, realizing the purification effect of the indoor air, and further entering the impeller cavity 27 under the action of the impeller assembly 23, and being accelerated in the impeller cavity 27 and then being discharged to the indoor space through the first air outlet 24. Thus, the air conditioner 100 can realize the circulation of indoor air, and during the circulation, the filter can purify and filter the indoor air, effectively removing dust, cooking fumes and other impurities in the air, and purifying the indoor air, i.e., the air conditioner 100 has a purification mode.

[0044] In the exhaust mode, the second air inlet is in an open state, i.e., the second air inlet communicates with the indoor space, the second air outlet 25 communicates with the outdoor space, and the first air inlet 112 and the first air outlet 24 are both in a closed state, and the impeller cavity 27 and the exhaust cavity 28 are in a connected state. In this way, the air flow in the indoor space can enter the second air inlet into the second air inlet flow channel 121, and enter the impeller cavity 27 from the second air inlet flow channel 121, and flow to the exhaust cavity 28 under the acceleration of the impeller cavity 27, and be discharged to the outdoor space through the second air outlet 25 of the exhaust cavity 28. Thus, the air conditioner 100 can discharge indoor air to the outdoor space, i.e., when the quality or odor of indoor air is abnormal, such as gas leakage or heavy fermentation odor in the indoor space, the air conditioner 100 can be switched to the exhaust mode to discharge the air flow with abnormal quality or odor in the indoor space to the outdoor space, i.e., the air conditioner 100 has an exhaust mode.

[0045] Further, the included angle between the mounting surface and one diagonal surface of the fixing seat 1 is less than 45°. Specifically, the first air inlet flow channel 111 can be configured to gradually shrink towards the communication with the impeller cavity 27, or the second air inlet flow channel 121 can be configured to gradually shrink towards the communication with the impeller cavity 27, or both the first air inlet flow channel 111 and the second air inlet flow channel 121 can be configured to gradually shrink towards the communication with the impeller cavity 27.

[0046] Through the above arrangement, in the fresh air mode, the outdoor airflow flows into the first air inlet flow channel 111 from the first air inlet 112, and gradually increases in pressure along the first air inlet flow channel 111 towards the impeller cavity 27, so that the airflow speed gradually increases, so that the airflow can be blown into the indoor space more quickly, thereby improving the fresh air efficiency; in the purification mode and the exhaust mode, the indoor air flows into the second air inlet flow channel 121 from the second air inlet, and gradually increases in pressure along the second air inlet flow channel 121 towards the impeller cavity 27, so that the airflow speed gradually increases, so that the indoor airflow can be purified more quickly or discharged to the outdoor space, so as to quickly improve the air quality, thereby improving the user's experience and improving the practicability of the air conditioner 100.

[0047] The air conditioner 100 according to the embodiment of the present application has the fresh air mode, the purification mode and the exhaust mode, that is, it can not only introduce fresh air from the outdoor space into the indoor space, but also purify the indoor air and discharge the indoor air with heavy odor to the outdoor space, so as to realize rich functions, meet the use requirements of users in different situations, have high practicability and simple structure, and quickly improve the indoor air, thereby improving the user's experience.

[0048] In some embodiments, as shown in Figure 4 The fixing seat 1 includes a first seat body 11 and a second seat body 12, both the first fixing seat 1 and the second fixing seat 1 are configured as a cavity structure, the first seat body 11 defines a first air inlet flow channel 111, and the second seat body 12 defines a second air inlet flow channel 121, the first air inlet flow channel 111 and the second air inlet flow channel 121 are communicated by connecting the first seat body 11 and the second seat body 12, and the impeller cavity 27 is communicated with the first air inlet 112 and the second air inlet by being communicated with the first air inlet flow channel 111 or the second air inlet flow channel 121.

[0049] The first seat body 11 and the second seat body 12 are connected and define a concave mounting space on the first side of the fixing seat 1, and in the specific design, as shown in Figure 2As shown, the right side wall of the first seat body part 11 is configured to extend towards the second seat body part 12 and tilt leftward to form a gradually narrowing first air inlet passage 111, while the right side wall of the second seat body part 12 is configured to extend towards the first seat body part 11 and tilt leftward to form a gradually narrowing second air inlet passage, and together define a concave mounting space on the right side of the fixed seat 1. The side surface of the first seat body part 11 towards the mounting space or the side surface of the second seat body part 12 towards the mounting space is configured as a mounting surface, so that the volute assembly 2 can be detachably mounted in the mounting space, so that the volute assembly 2 and the fixed seat 1 have a certain angle.

[0050] It can be understood that, compared to the volute assembly 2 and the seat body part being directly mounted, by setting the volute assembly 2 and the fixed seat 1 to have a certain angle, the volute assembly 2 is installed at the fixed seat 1 in an inclined manner, so that the volute assembly 2 and the fixed seat 1 have a larger mounting area, which is beneficial to improve the mounting stability of the volute assembly 2 and the seat body part, and can increase the connection passage area of the first air inlet passage 111 and the second air inlet passage 121 with the impeller cavity 27, which is beneficial to improve the flow speed of the airflow in the air conditioner 100, to improve the working efficiency of the air conditioner 100, and to improve the user's experience.

[0051] In some embodiments, as shown in Figure 2 The side surface of the first seat body part 11 towards the mounting space and the side surface of the second seat body part 12 towards the mounting space are perpendicular to each other, wherein the volute assembly 2 is configured as a rectangular structure as a whole, that is, when the volute assembly 2 is mounted into the mounting space, the adjacent side walls of the volute assembly 2 are respectively fitted on the side surface of the first seat body part 11 and the side surface of the second seat body part 12, so that the first seat body part 11 and the second seat body part 12 jointly limit and support the volute assembly 2, improving the mounting stability of the volute assembly 2 and the reliability of the air conditioner 100.

[0052] In some embodiments, the mounting surface is provided with a flow port 14, that is, the flow port 14 can be provided on the side surface of the first seat body part 11 towards the mounting space, or on the side surface of the second seat body part 12 towards the mounting space. The flow port 14 is used to communicate with the impeller cavity 27 of the volute assembly 2 to realize the communication between the first air inlet passage 111 and the second air inlet passage 121 and the impeller cavity 27.

[0053] Through the above arrangement, in the fresh air mode, the first air inlet 112 is in communication with the outdoor space, and the first air outlet 24 is in communication with the indoor space, the fresh air flow in the outdoor space can enter the first air inlet flow channel 111 from the first air inlet 112, and flow into the impeller cavity 27 through the flow hole, and after being accelerated in the impeller cavity 27, it can be discharged to the indoor space through the first air outlet 24, thereby realizing the fresh air function of the air conditioner 100; and in the purification mode, the second air inlet is in communication with the indoor space, and the first air outlet 24 is in communication with the indoor space, the airflow in the indoor space can enter the second air inlet flow channel 121 from the second air inlet, and after being filtered by the filter, it flows into the impeller cavity 27 through the flow hole, and after being accelerated in the impeller cavity 27, it is discharged to the indoor space through the first air outlet 24, thereby realizing the circulation of indoor air.

[0054] In some embodiments, the side surface of the first seat body part 11 towards the installation space is configured as a mounting surface, and the side wall of the volute assembly 2 is directly attached to the mounting surface to install the volute assembly 2 on the fixed seat 1. That is, as shown in Figure 4 The overall structural size of the first seat body part 11 is greater than that of the second seat body part 12, and the flow port 14 is arranged on the first seat body part 11, so that the flow port 14 has a larger size, thereby further increasing the speed of the airflow in the first air inlet flow channel 111 entering the impeller cavity 27, and improving the working efficiency of the air conditioner 100. During the working process of the air conditioner 100, after the outdoor air flows into the first air inlet flow channel 111 from the first air inlet 112, the outdoor airflow can directly flow out of the flow port 14 into the impeller cavity 27, and after the indoor air flows into the second air inlet flow channel 121 from the second air inlet, the indoor air flows into the first air inlet flow channel 111 along the second air inlet flow channel 121, and then the indoor airflow can flow out of the flow port 14 into the impeller cavity 27.

[0055] The angle between the mounting surface and the surface of the second side of the fixed seat 1 is less than 45°, and the first side and the second side are opposite sides of the fixed seat 1. That is, as shown in Figure 2 and Figure 3 The first side can be arranged as the right side of the fixed seat 1, and the second side can be arranged as the left side of the fixed seat 1, and the angle between the mounting surface and the surface of the second side of the fixed seat 1 is small, so that the mounting surface has a large extension length on the right side of the fixed seat 1, such as a large extension length in the up-down direction, thereby making the surface area of the mounting surface larger, which is beneficial to configuring the flow port 14 to have a larger opening size, increasing the air inlet amount of the first air inlet flow channel 111 into the impeller cavity 27, improving the air inlet efficiency of the air conditioner 100, and making the larger mounting surface effectively support the volute assembly 2 to improve the installation stability of the volute assembly 2.

[0056] In some embodiments, asFigure 2 As shown, the fixing seat 1 further comprises a connecting portion 13 connected between the first seat body portion 11 and the second seat body portion 12, and the connecting portion 13 is protrudingly arranged on the side of the fixing seat 1 away from the volute assembly 2 to form a flow passage 131 communicated between the first air inlet flow channel 111 and the second air inlet flow channel 121.

[0057] As shown, the side wall of the connecting portion 13 is configured as an arc-shaped structure, and the middle position of the connecting portion 13 is opposite to the connecting position of the first seat body portion 11 and the second seat body portion 12. By setting the middle position of the connecting portion 13 as the maximum deviation position, a flow passage 131 with relatively uniform width size is constructed, and an arc-shaped air guide surface is formed on the side wall of the flow passage 131 away from the volute assembly 2. After the indoor airflow flows into the second air inlet flow channel 121 from the second air inlet, the indoor airflow flows into the flow passage 131 and is guided by the arc-shaped air guide surface, so that the indoor airflow can stably flow into the first air inlet flow channel 111, avoiding the formation of turbulent flow of indoor airflow at the flow passage 131, and improving the reliability of the air conditioner 100.

[0058] As shown in some embodiments, Figure 3 and Figure 5 As shown, the volute assembly 2 comprises a volute cover 21 and a volute 22, the volute cover 21 is connected with the volute 22, and the volute cover 21 and the volute 22 define an air wheel cavity 27 and an exhaust cavity 28. That is, in actual design, the fixing seat 1, the volute cover 21 and the volute 22 can be respectively molded and fixedly connected to construct the air conditioner 100 as three structure pieces which can be respectively molded. This not only reduces the processing difficulty of the air conditioner 100 and saves design cost, but also directly processes an internal cavity for assembly when the volute cover 21 and the volute 22 are respectively molded, so as to define the air wheel cavity 27 and the exhaust cavity 28 after the three are connected and fixed, which is simple in molding and convenient in installation.

[0059] After specific installation, the volute cover 21 and the volute 22 define the air wheel cavity 27 and the exhaust cavity 28, wherein, as shown in Figure 6 the volute 22 is configured as a box open toward the volute cover 21, that is, the volute 22 has an air wheel groove 221 and an exhaust groove 222 on the side thereof facing the volute cover 21, so that the volute cover 21 closes the open side of the air wheel groove 221 and the exhaust groove 222 after the volute cover 21 and the volute 22 are fixed, to define the air wheel cavity 27 and the exhaust cavity 28. Thus, the directional flow of airflow is realized under the guidance of the volute cover 21 and the volute 22, so as to realize the discharge of airflow.

[0060] It can be understood that the first air inlet flow channel 111, the second air inlet flow channel 121, the wind wheel cavity 27 and the exhaust cavity 28 in the application can be constructed when the fixed seat 1 and the volute assembly 2 are respectively designed and formed, which greatly reduces the molding difficulty and is convenient to install, effectively reduces the installation difficulty, and facilitates the installation efficiency of the operator.

[0061] Further, as shown in Figure 7 The volute cover 21 is provided with an inlet hole 211, and the inlet hole 211 is arranged opposite to the overflow port 14. The airflow flowing out of the overflow port 14 can flow into the inlet hole 211, so as to realize the communication between the wind wheel cavity 27 and the first air inlet flow channel 111 and the second air inlet flow channel 121. In addition, the inlet hole 211 can be provided with an annular fence structure. Through the above arrangement, the airflow in the first air inlet flow channel 111 and the second air inlet flow channel 121 can smoothly flow into the wind wheel cavity 27. When the first air inlet flow channel 111 and the second air inlet flow channel 121 contain large-sized sundries, the annular fence structure can block the sundries, so as to avoid the sundries entering the wind wheel assembly 23 and causing damage to the wind wheel assembly 23, thereby improving the reliability of the air conditioner 100.

[0062] In some embodiments, the fixed seat 1 and the volute cover 21 are detachably connected, and the volute cover 21 and the volute 22 are detachably connected. That is, the volute 22, the volute cover 21 and the fixed seat 1 can be installed in sequence, and the volute cover 21 is installed between the volute 22 and the fixed seat 1, that is, the volute 22 and the fixed seat 1 are installed on both sides of the volute cover 21, so that the three shell parts can be assembled into an integral shell. In the actual installation process, the volute 22 and the fixed seat 1 can be fixedly connected with the volute cover 21. Specifically, the volute 22, the volute cover 21 and the fixed seat 1 can be provided with connecting holes, and the connecting holes on the volute cover 21 are multiple. The connecting holes of the volute 22 and part of the connecting holes of the volute cover 21 are opposite to each other and are detachably connected by connecting members such as bolts. The connecting holes of the fixed seat 1 and the other part of the connecting holes of the volute cover 21 are opposite to each other and are detachably connected by connecting members such as bolts. Thus, the volute 22 and the fixed seat 1 can be flexibly installed and detached with the volute cover 21, which is simple in structure and convenient to install.

[0063] Through the above arrangement, the air conditioner 100 is easy to disassemble and install. When the air conditioner 100 fails, the user or the maintenance personnel can conveniently disassemble the volute 22, the volute cover 21 and the fixed seat 1, so as to maintain the air conditioner 100. After the maintenance is completed, the air conditioner 100 can be conveniently assembled, which greatly improves the maintenance speed of the air conditioner 100 and improves the user experience.

[0064] In some embodiments, the volute 22 is provided with a third air outlet 26, and the third air outlet 26 is used for selectively connecting the wind wheel cavity 27 with the exhaust cavity 28. That is, as shown inFigure 6 As shown, the wind wheel cavity 27 and the exhaust cavity 28 are arranged in sequence along the left-right direction, and a third air outlet 26 is configured at the connection between the wind wheel cavity 27 and the exhaust cavity 28, that is, the airflow in the wind wheel cavity 27 can flow into the exhaust cavity 28 through the third air outlet 26 to be exhausted from the exhaust cavity 28.

[0065] The fifth valve 46 can be arranged at the third air outlet 26, and the fifth valve 46 is used for selectively opening and closing the third air outlet 26. The fifth valve 46 can be configured to be rotatable at the third air outlet 26, that is, the fifth valve 46 is used for selectively opening and closing the third air outlet 26 by driving the fifth valve 46 to rotate at the third air outlet 26. When the fifth valve 46 is rotated to be perpendicular to the air outlet direction of the third air outlet 26, the third air outlet 26 is closed, and at this time, the wind wheel cavity 27 and the exhaust cavity 28 are disconnected, that is, the airflow in the wind wheel cavity 27 cannot enter the exhaust cavity 28 from the third air outlet 26, and the exhaust function cannot be realized, that is, the air conditioner 100 can be in a fresh air mode or a purification mode. When the fifth valve 46 is rotated to be the same as the air outlet direction of the third air outlet 26, the third air outlet 26 is opened, and at this time, the wind wheel cavity 27 and the exhaust cavity 28 are connected, that is, the airflow in the wind wheel cavity 27 can enter the exhaust cavity 28 from the third air outlet 26, and the exhaust function can be realized, that is, the air conditioner 100 can be in an exhaust mode.

[0066] In some specific embodiments, as shown in Figure 2 and Figure 3 When the fourth valve 44 is installed to the first air inlet flow channel 111, the fifth valve 46 can be installed to the connection between the first air inlet flow channel 111 and the exhaust cavity 28. When the fifth valve 46 closes the exhaust cavity 28, the airflow in the exhaust cavity 28 cannot flow out, so that the air pressure in the exhaust cavity 28 is stable, and the airflow in the wind wheel cavity 27 cannot flow into the exhaust cavity 28, that is, the connection between the exhaust cavity 28 and the wind wheel cavity 27 is disconnected.

[0067] Optionally, the fifth valve 46 can be manually controlled or automatically controlled by connecting a driving member to the rotating shaft of the fifth valve 46, such as an electric motor, so that the motor shaft of the electric motor is drivingly connected to the rotating shaft of the fifth valve 46, thereby driving the fifth valve 46 by the electric motor to realize automatic control.

[0068] In some embodiments, the filter includes a purification module 31 and a filter screen 32. The purification module 31 is arranged in the first air inlet flow channel 111, and the filter screen 32 is arranged in the second air inlet flow channel 121. That is, as shown in Figure 2As shown, the filter screen 32 is installed at the second air inlet, and when the fan assembly 23 in the fan cavity 27 is started in the purification mode and the exhaust mode, the indoor air can be filtered and purified by the filter screen 32 before flowing into the second air inlet channel, so as to effectively remove dust, oil fume and other impurities in the air, and avoid the dust and impurities from accumulating in the air conditioner 100. When the filter screen 32 is damaged or deposits too much impurities, the filter screen 32 can be directly removed at the second air inlet for replacement and cleaning.

[0069] Further, as shown in Figure 1 and Figure 2 , the middle part of the first seat body 11 is provided with a mounting hole, and the purification module 31 can be installed in the mounting hole to extend into the first air inlet channel 111, so as to separate the first air inlet 112 and the fan cavity 27. In the fresh air mode, when the fan assembly 23 in the fan cavity 27 is started, the outdoor air flows into the second air inlet channel 121 from the first air inlet 112, and the outdoor air flows along the first air inlet channel 111 towards the fan cavity 27, and the outdoor air flows through the purification module 31 to achieve purification of the outdoor air. When the purification module 31 deposits too much impurities to affect the filtering performance, the purification module 31 can be removed from the mounting hole for repair and replacement. The purification module 31 can be HEPA.

[0070] In some specific embodiments, as shown in Figure 2 , the second air outlet 25 is in communication with the first air inlet channel 111, and the first valve 41 and the fourth valve 44 are both installed in the first air inlet channel 111, and the first valve 41 and the fourth valve 44 are used together to selectively close the first air inlet 112.

[0071] Specifically, in the exhaust mode, the second valve 42 and the fourth valve 44 are both in the open state, i.e. the second air inlet is in communication with the indoor space, the second air outlet 25 is in communication with the outdoor space, and the first valve 41 and the third valve 43 are both in the closed state, and the fan cavity 27 and the exhaust cavity 28 are in communication. In this way, the airflow in the indoor space can enter the second air inlet channel 121 from the second air inlet, and then enter the fan cavity 27 from the second air inlet channel 121, and flow to the exhaust cavity 28 under the acceleration of the fan cavity 27, and then flow into the first air inlet channel 111 from the second air outlet 25 of the exhaust cavity 28, and then flow out to the outdoor space from the first air outlet 24. Thus, the multifunctional use of the first air outlet 24 is realized, the communication between the air conditioner 100 and the outdoor space is reduced, the possibility of outdoor impurities entering the air conditioner 100 is reduced, and the reliability of the air conditioner 100 is improved.

[0072] It should be noted that the mouse-proof plate 45 can be arranged at the first air inlet 112 to avoid the mouse entering the air conditioner 100 from the first air inlet 112, and the reliability of the air conditioner 100 is further improved.
