[0037] A third aspect of the present invention further provides an air conditioner, characterized by comprising the ventilation module and the dust removal assembly.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0039] In the technical solution of the present invention, the housing assembly is used for the ventilation module, and the ventilation module is used for the air conditioner. The housing assembly includes a housing body, which is provided with a first opening, a second opening, and a third opening. The first opening and the third opening can communicate with the interior (i.e., the first area), and the second opening can communicate with the exterior (i.e., the second area). In particular, the third opening is adapted to obtain the dust generated during the dust removal process of the dust removal assembly of the air conditioner. In the dust removal mode of the air conditioner (at this time, the housing assembly is in the second state), the drive motor in the housing assembly drives the indoor air to enter the housing body through the third opening and be led out to the exterior through the second opening. During the process of air being introduced into the third opening, a pressure difference can be generated at the dust removal assembly to generate suction, which can prevent the dust generated during the dust removal process of the dust removal assembly from drifting into the interior and causing indoor air pollution. In this solution, the ventilation module is used to clean the dust to prevent the dust from floating in the indoor air. Therefore, there is no need to additionally increase a dedicated dust removal channel for conducting dust, saving the internal space of the air conditioner. And the power for driving the dust out to the exterior is provided by the drive motor of the ventilation module, without the need to additionally increase a drive motor, reducing the number of motors of the air conditioner and lowering the material cost of the air conditioner.

[0040] Furthermore, in the present invention, in the fresh air mode of the air conditioner (at this time, the housing assembly is in the first state), the drive motor in the housing assembly drives the outdoor air to enter the housing body through the second opening and be led out of the housing body through the first opening to the interior. And the housing assembly is configured to make the driving direction of the drive motor the same in the first state and the second state. In this solution, since the driving direction of the drive motor is the same in the two states of the housing assembly, the fan blade of the drive motor does not need to switch the rotation direction (in the related art, since the air flow directions in the two states are opposite, the fan blade of the motor needs to switch the rotation direction), so that the fan blade can always maintain the best driving efficiency (in the related art, the fan blade can only maintain a relatively high driving efficiency during forward rotation, and the driving efficiency during reverse rotation is relatively low).

[0041] Furthermore, in the present invention, since the driving direction of the driving motor remains unchanged in the first state and the second state of the housing assembly, the ventilation module having this housing assembly can switch the ventilation mode more quickly, and the operating state of the driving motor does not need to be adjusted too much during the process of the ventilation module switching the ventilation mode. In the related art, when the method of making the driving motor rotate forward and backward is used to switch the ventilation mode, for example, when the ventilation module switches from the fresh air mode to the dust removal mode, the driving motor needs to switch from forward rotation to reverse rotation, and this switching process takes a long time. When the set switching process is too short, the driving motor decelerates and accelerates in the reverse direction in a short time, which will cause a short circuit, reducing the service life of the driving motor and seriously burning the motor in severe cases.

[0082] The realization, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiments

[0083] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0084] The air exchange function modes of an air conditioner generally include a fresh air mode, a dust removal mode, an exhaust mode, a circulating air mode, etc. Among them, the fresh air mode means that the outdoor air is drawn into the room through the air conditioner. The dust removal mode means dust removal of the filter provided in the air conditioner. During the dust removal process, in order to prevent the dust separated from the filter from spreading into the indoor air, a dust removal channel is usually provided to guide the dust separated from the filter to the outside. The exhaust mode means that the indoor air is drawn out of the room through the air conditioner. The circulating air mode means that the indoor air is drawn into the air conditioner and discharged into the room after being processed by the air conditioner. To realize the switching of the air exchange function of the air conditioner, the air conditioner usually includes a plurality of drive motors, and each drive motor can drive each function mode. However, this setting method greatly increases the production cost of the air conditioner.

[0085] Therefore, the applicant considered multiplexing the drive motors in the fresh air mode, dust removal mode, exhaust mode, and recirculating air mode, that is, integrating the drive methods of each functional mode into the drive motor, so as to reduce the number of drive motors of the air conditioner and lower the material cost of the air conditioner. Since the air flow direction in the fresh air mode (entering the room from the outside) is opposite to the air flow direction in the dust removal mode (discharging from the room to the outside), it is necessary to change the rotation direction of the drive motor to facilitate the switching of the air exchange function mode of the air conditioner. However, the applicant found that the fan blade connected to the drive motor can only maintain the best drive efficiency in a certain rotation direction (i.e., the drive motor rotates forward or backward) due to its own structural design. And when the air conditioner switches from the fresh air mode to the dust removal mode, the drive motor needs to switch its rotation direction. Hereinafter, taking the drive motor switching from forward rotation to reverse rotation as an example. When the rotation direction of the drive motor is switched, due to the existence of the rotational inertia generated by the forward rotation of the drive motor, the drive motor still has a tendency to rotate forward. At this time, part of the driving force for the reverse rotation of the drive motor will be used to offset the forward inertia, resulting in energy loss. In addition, the drive motor decelerating and accelerating in the reverse direction in a short time will cause a short circuit, which will reduce the service life of the drive motor and may cause the drive motor to burn out seriously.

[0086] In order to prevent the air entering the air conditioner from flowing around inside the air conditioner and affecting the working efficiency in each mode after the air exchange mode of the air conditioner is switched, the air conditioner is usually provided with multiple channels, and each channel corresponds to the air flow path in each functional mode respectively. However, this setting method will cause the overall size of the air conditioner to increase.

[0087] In view of this, please refer to Figures 1 to 20 , the first aspect of the present invention provides a housing assembly 100, which is used for a ventilation module, and the ventilation module is used for an air conditioner. Please refer to Figure 1 , the housing assembly 100 includes a housing body, the housing body is provided with a first opening 113, a second opening 123, and a third opening 124. The first opening 113 and the third opening 124 can communicate with a first area 20, and the second opening 123 can communicate with a second area 30. In one embodiment, the first area 20 can be the interior of the room, and the second area 30 can be the outside. In another embodiment, the first area 20 can be a certain room inside the room, and the second area 30 can be another room inside the room. For the convenience of description, hereinafter, the case where the first area 20 is the interior of the room and the second area 30 is the outside will be taken as an example for illustration. In particular, the third opening 124 is adapted to communicate with the first area 20 and is adapted to circulate the air flow generating dust by the drive dust removal assembly 40.

[0088] The housing assembly 100 has a first state and a second state. When the housing assembly 100 is in the first state, the air conditioner can be in the fresh air mode. Please refer to Figure 2When the housing assembly 100 is in the second state, the air conditioner can be in the dust removal mode. Please refer to Figure 3 The first opening 113 can be the air outlet of the air conditioner in the indoor area (i.e., the first area 20), and the second opening 123 can be the air outlet / air inlet of the air conditioner in the outdoor area (i.e., the second area 30) (when it is necessary to discharge air from the indoor to the outdoor, the second opening 123 is the air outlet of the air conditioner in the outdoor area; when it is necessary to intake air from the outdoor to the indoor, the second opening 123 is the air inlet of the air conditioner in the outdoor area), and the third opening 124 can be the dust removal port of the air conditioner. When the housing assembly 100 is in the first state (i.e., the air conditioner is in the fresh air mode), the drive motor 190 drives the air in the outdoor area (i.e., the second area 30) to enter the housing body through the second opening 123 and be discharged to the indoor area (i.e., the first area 20) through the first opening 113. When the housing assembly 100 is in the second state (i.e., the air conditioner is in the dust removal mode), the drive motor 190 drives the air in the indoor area (i.e., the first area 20) to enter the housing body through the third opening 124, so that there is a pressure difference at the dust removal assembly 40 to generate suction. The existence of the suction can prevent the dust generated during the dust removal process of the dust removal assembly 40 from drifting into the indoor and causing indoor air pollution. By integrating and reusing the air outlet in the dust removal mode (second state) and the air inlet in the fresh air mode (first state), there is no need to additionally increase a dedicated dust removal channel for conducting dust, saving the internal space of the air conditioner. Moreover, in the present invention, both the dust removal mode and the fresh air mode of the air conditioner are driven by the same drive motor 190, without the need to additionally add a drive motor 190 for the dust removal mode of the air conditioner, reducing the number of motors of the air conditioner and lowering the material cost of the air conditioner. The driving direction of the drive motor 190 when the housing assembly 100 is in the first state is the same as the driving direction of the drive motor 190 when the housing assembly 100 is in the second state, that is, when the air conditioner switches the functional mode, the driving direction of the drive motor 190 always remains unchanged, effectively improving the conversion efficiency of the drive motor 190 and on the other hand also improving the service life of the drive motor 190.

[0089] Please refer to Figures 1 to 18, in some embodiments, the housing assembly 100 further includes a first valve group 160, a second valve group 170, and a third valve group 180, and the housing body further includes a first housing 110 and a second housing 120. In one embodiment, the first valve group 160 may be a combination of multiple valves that can control the communication or separation between the first chamber 111 and the second chamber 112 by opening or closing states, and some of these valves can also be used to control the opening and closing states of the first opening 113. In another embodiment, the first valve group 160 is composed of a single valve. When the valve is in the closed state, the first chamber 111 can be separated from the second chamber 112, and the first opening 113 can communicate with the first chamber 111. When the valve is in the open state, the first chamber 111 can communicate with the second chamber 112, and the first opening 113 is closed by the valve so that the first opening 113 can be non - communicating with the first chamber 111. For the convenience of description, the following will take the first valve group 160 as a single valve as an example for illustration. The first housing 110 defines a first chamber 111 and a second chamber 112, and the first opening 113 can communicate with the first chamber 111. Please refer to Figure 1 and Figure 3 , the first valve group 160 is disposed in the first housing 110 and can separate or connect the first chamber 111 and the second chamber 112. Please refer to Figure 1 , when the first valve group 160 separates the first chamber 111 and the second chamber 112, the first opening 113 can communicate with the first chamber 111. Please refer to Figure 3 , when the first valve group 160 connects the first chamber 111 and the second chamber 112, the first valve group 160 can close the first opening 113 so that the first opening 113 is separated from and non - conductive to the first chamber 111. In some other embodiments, the first valve group 160 is only used to control the communication and separation state between the first chamber 111 and the second chamber 112, and the opening and closing states of the first opening 113 can be controlled by setting other valve groups.

[0090] Please refer to Figure 1 and Figure 2 , the second housing 120 defines a third chamber 121 and a fourth chamber 122, and the second valve group 170 is disposed in the second housing 120 and can separate or connect the third chamber 121 and the fourth chamber 122. In some embodiments, please refer to Figure 1, the third chamber 121 can always communicate with the second chamber 112, and the second opening 123 can always communicate with the third chamber 121. In some other embodiments, a valve may be provided between the third chamber 121 and the second chamber 112, and a valve may also be provided at the second opening 123. When the air conditioner is in the working state, the valve between the third chamber 121 and the second chamber 112 and the valve at the second opening 123 are opened so that the second chamber 112 can communicate with the third chamber 121, and the second opening 123 can communicate with the third chamber 121. When the air conditioner is in the shutdown state or when the second opening 123 does not need to discharge air into the second area 30, the valve between the third chamber 121 and the second chamber 112 and the valve at the second opening 123 are closed to prevent the air in the second area 30 from pouring into the air conditioner through the second opening 123. For the convenience of description, the following takes the example that the third chamber 121 always communicates with the second chamber 112 and the second opening 123 always communicates with the third chamber 121 for illustration. The third opening 124 can communicate with the fourth chamber 122. Specifically, please refer to Figure 1 and Figure 3 , the third valve group 180 is disposed in the fourth chamber 122 and can open or close the third opening 124 so that the third opening 124 can communicate with or be separated from the fourth chamber 122.

[0091] In one embodiment, the third valve group 180 can be a combination of multiple valves, and these valves can control the mutual communication or separation of the third opening 124 and the fourth chamber 122 by the open or closed state. In another embodiment, the third valve group 180 is composed of a single valve. When the valve is in the closed state, the third opening 124 can be separated from the fourth chamber 122. When the valve is in the open state, the third opening 124 can communicate with the fourth chamber 122 so that the first area 20 communicating with the third opening 124 can communicate with the fourth chamber 122. For the convenience of description, the following takes the example that the third valve group 180 is a single valve for illustration.

[0092] Please refer to Figure 6, in some embodiments, the drive motor 190 may be disposed between the fourth chamber 122 and the first chamber 111. In other embodiments, the drive motor 190 may be disposed at any position of the housing assembly 100, and the drive fan portion of the drive motor 190 is disposed between the fourth chamber 122 and the first chamber 111. In the present invention, by providing the first valve group 160, the second valve group 170, and the third valve group 180 in the housing body, the first chamber 111, the second chamber 112, the third chamber 121, and the fourth chamber 122 can be interconnected or separated from each other. And the drive motor 190 disposed between the fourth chamber 122 and the first chamber 111 can drive the air in the fourth chamber 122 to flow into the first chamber 111, so that the air entering the housing body in different functional modes can reuse these chambers in a mode-divided manner, saving the space for setting the dust removal channel in the dust removal mode of the air conditioner.

[0093] Please refer to Figure 2 , Figure 16 and Figure 17 , in some embodiments, when the housing assembly 100 is in the first state, that is, when the air conditioner is in the fresh air mode, the air in the second region 30 flows into the housing assembly 100 through the second opening 123 and into the first region 20 through the first opening 113. In a specific embodiment, please refer to Figure 2, the second valve group 170 located between the third chamber 121 and the fourth chamber 122 opens to connect the third chamber 121 and the fourth chamber 122. Since the third chamber 121 is connected to the second area 30 (i.e., outdoors), at this time, the second chamber 112, the second area 30, the third chamber 121, and the fourth chamber 122 are all connected to each other. The first valve group 160 closes to separate and disconnect the first chamber 111 from the second chamber 112, and the first opening 113 is connected to the first chamber 111. The third valve group 180 closes to close the third opening 124. The driving motor 190 starts to create a pressure difference between the air in the fourth chamber 122 and the first chamber 111, so that the air in the second area 30 can enter the housing assembly 100 through the second opening 123, flow from the third chamber 121 to the fourth chamber 122, then flow to the first chamber 111 under the drive of the driving motor 190, and then flow to the first area 20 (i.e., indoors) through the first opening 113 connected to the first chamber 111. During this process, since there is a first valve group 160 between the second chamber 112 and the first chamber 111 and the first valve group 160 is in the closed state, the air flowing from the third chamber 121 to the second chamber 112 cannot directly flow to the first chamber 111. The flow path of the air in the fresh air mode is defined to prevent the air from moving around in the housing assembly 100. Also, since the third opening 124 can collect the dust generated by the dust removal assembly 40, at this time, the third valve group 180 is in the closed state, making the third opening 124 in the closed state, that is, the third opening 124 is not connected to the fourth chamber 122. Thus, it is avoided that the air entering the housing assembly 100 flows to the first area 20 through the third opening 124, and further the dust generated by the dust removal assembly 40 is blown into the first area 20 (i.e., indoors), causing air pollution.

[0094] Please refer to Figure 3 , Figure 14 and Figure 15 , when the housing assembly 100 is in the second state, that is, when the air conditioner is in the dust removal mode, the air in the first area 20 flows into the housing assembly 100 through the third opening 124 under the drive of the driving motor 190 and flows to the second area 30 through the second opening 123. In the specific implementation, please refer to Figure 3, the first valve group 160 located in the first chamber 111 and the second chamber 112 is opened, the first chamber 111 and the second chamber 112 can communicate with each other, and at the same time the first valve group 160 can close the first opening 113. Since the third chamber 121 communicates with the second region 30 (i.e., the outdoors), the first chamber 111, the second chamber 112, the third chamber 121, and the second region 30 can communicate with each other. The third valve group 180 provided in the fourth chamber 122 is opened so that the third opening 124 is in an open state, enabling the third opening 124 to communicate with the fourth chamber 122, and further enabling the fourth chamber 122 to communicate with the first region 20 (i.e., the indoors). The second valve group 170 is in a closed state to separate and non-conduct the third chamber 121 and the fourth chamber 122. The drive motor 190 is started to create a pressure difference between the air in the fourth chamber 122 and the first chamber 111, so that the air in the first region 20 flows through the third opening 124 into the fourth chamber 122, and then flows from the fourth chamber 122 to the first chamber 111 under the drive of the drive motor 190. Since the first opening 113 is closed by the first valve group 160, the air flow cannot flow out through the first opening 113. Therefore, the air flow can only flow through the opened first valve group 160 into the second chamber 112 and then into the third chamber 121 communicating with the second chamber 112. Since the second valve group 170 is in a closed state and the third chamber 121 and the fourth chamber 122 are not connected, the air flowing into the third chamber 121 flows through the second opening 123 into the second region 30 (i.e., the outdoors). The states of the first valve group 160, the second valve group 170, and the third valve group 180 define the air flow path in the dust removal mode, preventing the air carrying dust from randomly moving in the housing assembly 100 and contaminating other components in the housing assembly 100.

[0095] Please refer to Figure 2 , when the housing assembly 100 is in the first state, the air flow direction is from the second region 30 to the first region 20. Please refer to Figure 3 , when the housing assembly 100 is in the second state, the air flow direction is from the first region 20 to the second region 30, that is, the air flow directions between the first region 20 and the second region 30 are opposite in these two states. In the present invention, by providing the first valve group 160 and the second valve group 170 in the housing assembly 100, when the housing assembly 100 is in different states, by controlling the opening and closing states of the first valve group 160 and the second valve group 170, no matter whether the air flow is from the first region 20 to the second region 30 or from the second region 30 to the first region 20, there is a process in which the air flows from the fourth chamber 122 to the first chamber 111 in the air flow path. Please refer to Figure 6, the driving motor 190 is disposed between the fourth chamber 122 and the first chamber 111, so that the driving motor 190 only needs to drive in the direction pointing from the fourth chamber 122 to the first chamber 111. Thus, the fan blades of the driving motor 190 do not need to switch the rotation direction, enabling the driving motor 190 to always maintain the best driving efficiency and increasing the service life of the driving motor 190. Specifically, please refer to Figure 2 , when the housing assembly 100 is in the first state, that is, when the air conditioner is in the fresh air mode, the flow path of the air flow is from the second region 30 through the second opening 123 into the third chamber 121, through the second valve group 170 into the fourth chamber 122, and then flows towards the first chamber 111 under the drive of the driving motor 190, and finally flows into the first region 20 through the first opening 113. Please refer to Figure 3 , when the housing assembly 100 is in the second state, that is, when the air conditioner is in the dust removal mode, the flow path of the air flow is from the first region 20 through the third opening 124 into the fourth chamber 122, and flows towards the first chamber 111 under the drive of the driving motor 190, through the first valve group 160 into the second chamber 112, and then into the third chamber 121 communicating with the second chamber 112, and finally flows into the second region 30 through the second opening 123 communicating with the third chamber 121.

[0096] Please refer to Figure 5 , Figure 18 and Figure 15 , in some embodiments, the air exchange function mode of the air conditioner may further include an exhaust mode. To avoid the air entering the housing assembly 100 being affected by the dust generated by the dust removal assembly 40 in this mode, please refer to Figure 5 , in some embodiments, the housing body is further provided with a fourth opening 125. The fourth opening 125 communicates with the fourth chamber 122, and the fourth opening 125 can communicate with the first region 20 (i.e., the interior). The housing assembly 100 further includes a third state. Please refer to Figure 5 , when the housing assembly 100 is in the third state, please refer to Figure 18 and Figure 15, the air conditioner with the housing assembly 100 is in the exhaust mode. When the housing assembly 100 is in the third state, the drive motor 190 can drive the air in the first region 20 to enter the housing main body through the fourth opening 125 and be discharged to the second region 30 through the second opening 123. The driving direction of the drive motor 190 of the housing assembly 100 in the third state is the same as that of the drive motor 190 of the housing assembly 100 in the first state. In one embodiment, the opening and closing state of the fourth opening 125 can be controlled by separately setting other structures. In another embodiment, the third valve group 180 is further configured to be able to open or close the fourth opening 125. For the convenience of description, the following takes the third valve group 180 controlling the opening and closing state of the fourth opening 125 as an example for illustration.

[0097] Please refer to Figure 5 , in a specific embodiment, when the housing assembly 100 is in the third state, that is, when the air conditioner with the housing assembly 100 is in the exhaust mode, the first valve group 160 is opened so that the first chamber 111 can communicate with the second chamber 112, and the first opening 113 is closed by the first valve group 160. The second valve group 170 is in a closed state so that the third chamber 121 is separated from the fourth chamber 122 and not communicated. The third valve group 180 is configured to open the fourth opening 125 and close the third opening 124, so that the first region 20 (i.e., the indoor) can communicate with the fourth chamber 122 through the fourth opening 125. The drive motor 190 is started so that there is a pressure difference between the air in the fourth chamber 122 and the first chamber 111, so that the air in the first region 20 can flow into the fourth chamber 122 through the fourth opening 125 and enter the first chamber 111 under the drive of the drive motor 190. At this time, since the first valve group 160 is in an open state and the first opening 113 is closed by the first valve group 160, the air entering the first chamber 111 can flow through the first valve group 160 to the second chamber 112 and then to the third chamber 121 communicating with the second chamber 112. Also, since the second valve group 170 is in a closed state, the third chamber 121 is separated from the fourth chamber 122, and the air flowing into the third chamber 121 can only flow to the second region 30 (i.e., the outdoor) through the second opening 123. In this exhaust mode, since the second valve group 170 is in a closed state, separating the third chamber 121 from the fourth chamber 122, the drive motor 190 will not affect the air in the second region 30 (i.e., the outdoor) communicating with the third chamber 121, effectively improving the exhaust efficiency.

[0098] Refer to Figure 4 , Figure 18 and Figure 17, in some other embodiments, the air exchange function mode of the air conditioner may further include a circulating air mode. To prevent the air entering the housing assembly 100 in this mode from being affected by the dust generated by the dust removal assembly 40, the housing body is further provided with a fourth opening 125. Refer to Figure 4 , when the housing assembly 100 is in the fourth state, the air conditioner having the housing assembly 100 is in the circulating air mode. When the housing assembly 100 is in the fourth state, the drive motor 190 can drive the air in the first region 20 to enter the housing body through the fourth opening 125 and be discharged to the first region 20 through the first opening 113. The driving direction of the drive motor 190 of the housing assembly 100 in this fourth state is the same as the driving direction of the drive motor 190 of the housing assembly 100 in the first state.

[0099] Refer to Figure 4 , Figure 18 and Figure 17 , in a specific embodiment, when the housing assembly 100 is in the fourth state, that is, when the air conditioner having the housing assembly 100 is in the circulating air mode, the first valve group 160 is closed to separate the first chamber 111 from the second chamber 112 and make them not communicate with each other, while the first opening 113 is in an open state so that the first opening 113 communicates with the first chamber 111, and then the first chamber 111 communicates with the first region 20 (i.e., the indoor) through the first opening 113. The second valve group 170 is closed to separate the third chamber 121 from the fourth chamber 122. The third valve group 180 is in a state of opening the fourth opening 125 and closing the third opening 124 so that the fourth opening 125 communicates with the fourth chamber 122, and then the fourth chamber 122 communicates with the first region 20 (i.e., the indoor) through the fourth opening 125. The third opening 124 is closed to separate the third opening 124 from the fourth chamber 122. The drive motor 190 is started to make the air pressure difference exist between the fourth chamber 122 and the first chamber 111, and then the air in the first region 20 flows into the fourth chamber 122 through the fourth opening 125. Since the second valve group 170 is closed, the air cannot flow to the third chamber 121 and can only flow to the first chamber 111 under the drive of the drive motor 190. Also, since the first valve group 160 is in a closed state, the air flowing into the first chamber 111 can only flow to the first region 20 (i.e., the indoor) through the first opening 113. The circulating air mode of the air conditioner is beneficial to improving the refrigeration and heating efficiency of the air conditioner. When the housing assembly 100 is in this fourth state and the air conditioner is in the circulating air mode, the closed first valve group 160 can prevent the air entering the first chamber 111 from flowing to the second chamber 112 and then flowing to the second region 30 (i.e., the outdoor) through the third chamber 121. The closed second valve group 170 can prevent the air in the second region 30 (i.e., the outdoor) from being driven by the drive motor 190 to enter the housing assembly 100, resulting in a reduction in the circulation efficiency of the circulating air mode of the air conditioner.

[0100] Please refer to Figure 2 、 Figure 6 and Figure 16 In some embodiments, the third valve group 180 can also simultaneously close the third opening 124 and the fourth opening 125. In other embodiments, the third valve group 180 is used to control the opening and closing states of the third opening 124, and the opening and closing states of the fourth opening 125 can be controlled by other valve groups, that is, the housing assembly 100 can be provided with other valve groups for controlling the opening and closing states of the fourth opening 125. For the convenience of description, the following takes the third valve group 180 controlling the opening and closing states of the third opening 124 and the fourth opening 125 as an example for illustration. When the third valve group 180 simultaneously closes the third opening 124 and the fourth opening 125, the housing assembly 100 is in the first state, that is, the air conditioner is in the fresh air mode. Specifically, the first valve group 160 is in the closed state to separate the first chamber 111 from the second chamber 112, and the first opening 113 is in the open state to connect the first chamber 111 to the first area 20 (i.e., the indoor area). The second valve group 170 is in the open state to connect the third chamber 121 to the fourth chamber 122, so that the fourth chamber 122 can be connected to the second area 30 (i.e., the outdoor area) through the third chamber 121. The third valve group 180 is in the fully closed state to close both the third opening 124 and the fourth opening 125, so that the third opening 124 and the fourth opening 125 can be separated from the fourth chamber 122. The drive motor 190 is started to create a pressure difference between the air in the fourth chamber 122 and the air in the first chamber 111, so that the air in the second area 30 (i.e., the outdoor area) can flow into the third chamber 121 through the second opening 123, flow to the fourth chamber 122, and then flow to the first chamber 111 under the drive of the drive motor 190, and finally flow into the first area 20 (i.e., the indoor area) through the first opening 113.

[0101] Please refer to Figure 3 、 Figure 9 、 Figure 11 and Figure 14, in some embodiments, the third valve group 180 can also only close the fourth opening 125 while keeping the third opening 124 open. At this time, the housing assembly 100 is in the second state, that is, the air conditioner is in the dust removal mode. Specifically, the first valve group 160 opens to connect the first chamber 111 to the second chamber 112, and the first valve group 160 can close the first opening 113 to separate the first area 20 (i.e., the indoor area) from the first chamber 111, preventing the air carrying dust from flowing into the first area 20 (i.e., the indoor area) through the first opening 113. The second valve group 170 closes to separate the third chamber 121 from the fourth chamber 122. The closed second valve group 170 can prevent the air in the second area 30 (i.e., the indoor area) from entering the housing assembly 100 when the drive motor 190 is driving, which affects the dust removal efficiency. The third valve group 180 is in a state of opening the third opening 124 and closing the fourth opening 125, so that the first area 20 can be connected to the fourth chamber 122 through the third opening 124. The drive motor 190 is started to create a pressure difference between the air in the fourth chamber 122 and the air in the first chamber 111. As a result, the air in the first area 20 (i.e., the indoor area) flows through the third opening 124 into the fourth chamber 122, and is driven by the drive motor 190 to the first chamber 111, then flows to the second chamber 112, and flows through the second opening 123 connected to the third chamber 121 to the second area 30 (i.e., the outdoor area). In this dust removal mode, closing the fourth opening 125 can prevent the dust carried by the air flowing in through the third opening 124 from flowing back into the first area 20 (i.e., the indoor area) through the fourth opening 125, causing air pollution in the first area 20.

[0102] Please refer to Figures 1 to 19, in some embodiments, to effectively control the opening and closing states of the third opening 124 and the fourth opening 125, the third opening 124 and the fourth opening 125 may be circumferentially distributed along the circumferential direction of the first rotation axis. The third valve group 180 includes a first rotating portion 182 configured to be able to rotate around the first rotation axis. The specific shape of the first rotating portion 182 may be a strip-shaped arc wall structure, a fan-shaped structure, or other structures capable of rotating around the first rotation axis. To facilitate the description of the positional state relationship of the third valve group 180, it is defined that the first rotating portion 182 has a first position, a second position, and a third position. Among them, during the process of the first rotating portion 182 rotating to the first position, the first rotating portion 182 can rotate around the first rotation axis to close the third opening 124 and open the fourth opening 125. At this time, the housing assembly 100 is in the third state or the fourth state, that is, the air conditioner is in the exhaust mode or the circulating air mode. During the process of the first rotating portion 182 rotating to the second position, the first rotating portion 182 can rotate around the first rotation axis to close the fourth opening 125 and open the third opening 124. At this time, the housing assembly 100 is in the second state, that is, the air conditioner is in the dust removal mode. During the process of the first rotating portion 182 rotating to the third position, the first rotating portion 182 can rotate around the first rotation axis to close the third opening 124 and the fourth opening 125. At this time, the housing assembly 100 is in the first state, that is, the air conditioner is in the fresh air mode.

[0103] In some embodiments, the second valve group 170 has a second rotating portion, which may be a plate-like structure, a spherical structure, or an arc wall-shaped structure, etc., and other structures capable of blocking and opening the third chamber 121 and the fourth chamber 122. The second rotating portion can rotate around the second rotation axis so that the second valve group 170 can be opened or closed, thereby enabling the third chamber 121 and the fourth chamber 122 to be communicated or separated. Similarly, the first valve group 160 may have a third rotating portion, which may be a plate-like structure, a spherical structure, or an arc wall-shaped structure, etc., and other structures capable of blocking and opening the first chamber 111 and the second chamber 112. The third rotating portion can rotate around the third rotation axis so that the first valve group 160 can be opened or closed, thereby enabling the first chamber 111 and the second chamber 112 to be communicated or separated.

[0104] Please refer to Figures 8 to 19 , in some embodiments, in order to enable the third valve group 180 to effectively close the third opening 124 and the fourth opening 125 simultaneously, the third valve group 180 further defines a valve cavity 181. Please refer to Figure 8, the first rotating part 182 is arranged in the valve cavity 181, and both the third opening 124 and the fourth opening 125 communicate with the valve cavity 181. The valve cavity 181 is also provided with a fifth opening 1811 communicating with the fourth chamber 122. Please refer to Figures 8 to 10 , the third opening 124, the fourth opening 125 and the fifth opening 1811 are distributed around the first rotation axis, and the first rotating part 182 can move along the inner wall of the valve cavity 181. Please refer to Figure 10 , when the first rotating part 182 is in the first position, it can cover the third opening 124 and keep the fourth opening 125 in an open state, so that the third opening 124 is separated from the fourth chamber 122, and the fourth opening 125 communicates with the fourth chamber 122 through the fifth opening 1811. Please refer to Figure 9 , when the first rotating part 182 is in the second position, it can cover the fourth opening 125 and keep the third opening 124 in an open state, so that the fourth opening 125 is separated from the fourth chamber 122, and the third opening 124 can communicate with the fourth chamber 122 through the fifth opening 1811. Please refer to Figure 8 , when the first rotating part 182 is in the third position, it can cover the fifth opening 1811, so that the third opening 124 and the fourth opening 125 are separated from the fourth chamber 122.

[0105] In some embodiments, the first valve group 160, the second valve group 170, and the third valve group 180 can all be provided with control motors, so that the opening and closing states of the first valve group 160, the second valve group 170, and the third valve group 180 can automatically change with the switching of the functional modes of the air conditioner, and the control motors can provide kinetic energy for the rotation of the first rotating part 182, the second rotating part, and the third rotating part. And it can also provide a supporting force for the open state and the closed state of the first valve group 160, the second valve group 170, and the third valve group 180, so that the first valve group 160, the second valve group 170, and the third valve group 180 can maintain the open state or the closed state. For the convenience of description, the first position, the second position, and the third position of the third valve group 180 are taken as examples for illustration below. When the first rotating part 182 needs to be switched from the first position to the second position, the control motor drives the first rotating part 182 to rotate around the first rotation axis, so that the first rotating part 182 disengages from the first position and rotates towards the second position. After the first rotating part 182 rotates to the second position, the control motor stops driving, so that the first rotating part 182 can be kept in the second position, so that the third opening 124 can maintain the open state. When the first rotating part 182 needs to be switched from the second position to the third position, the control motor drives the first rotating part 182 to rotate around the first rotation axis, so that the first rotating part 182 disengages from the second position and rotates towards the third position under the drive of the control motor. After the first rotating part 182 rotates to the third position, the control motor stops driving, so that the first rotating part 182 can be kept in the third position, so that the third opening 124 and the fourth opening 125 can maintain the closed state.

[0106] Please refer to Figures 11 to 19 , in some embodiments, the housing assembly 100 further includes a dust collection box 130 disposed in the housing body, and the dust collection box 130 can collect the dust that enters the housing body through the third opening 124. Specifically, please refer to Figure 11 , the dust collection box 130 can be disposed in the channel where the third opening 124 communicates with the fourth cavity, and the dust collection box 130 is provided with a dust collection port 1311 facing the third opening 124. Please refer to Figure 11When the housing assembly 100 is in the second state and the air conditioner is in the dust removal mode, the driving motor 190 can drive the air in the first area 20 (i.e., indoors) to enter the third opening 124. The air entering the third opening 124 can drive the dust collected by the dust removal assembly 40 at the third opening 124 to flow into the dust box 130 through the dust collecting port 1311, and then flow into the fourth chamber 122 from the dust box 130. The air flowing into the fourth chamber 122 flows into the first chamber 111 under the drive of the driving motor 190, and flows into the second chamber 112 through the first valve group 160, and then flows into the second area 30 (i.e., outdoors) through the second opening 123 connected to the third chamber 121. The dust box 130 can prevent dust from floating in the air and flowing to the first area 20 (i.e., indoors), causing the air in the first area 20 to be polluted, and can also prevent the dust-carrying air entering through the third opening 124 from excessively polluting the components and chamber channels set in the housing assembly 100.

[0107] See also Figure 14 In some embodiments, the dust box 130 includes a dust collecting shell 131 and a first filter 132 disposed in the dust collecting shell 131, and the first filter 132 can filter the air entering the dust box 130. In a specific embodiment, the dust collecting shell 131 is provided with a dust collecting port 1311 on the side facing the third opening 124, and an air guide port 1312 is provided on the side away from the third opening 124. When the housing assembly 100 is in the second state and the air conditioner is in the dust removal mode, the driving motor 190 can drive the air in the first area 20 (i.e., indoors) to enter the third opening 124, and the air entering the third opening 124 can drive the dust collected by the dust removal assembly 40 at the third opening 124 to flow into the dust box 130 through the dust collecting port 1311. After entering the dust box 130, the air carrying dust passes through the first filter 132, so that the dust can be stripped from the air by the first filter 132 and temporarily stored in the dust box 130. The filtered air flows to the fourth chamber 122 through the air guide port 1312, and then flows into the first chamber 111 driven by the drive motor 190, and flows into the second chamber 112 through the first valve group 160 in the open state, and then flows into the second area 30 (i.e., outdoors) through the second opening 123 connected to the third chamber 121. The provision of the first filter 132 can effectively improve the dust collection effect of the dust box 130, and can prevent the dust-carrying air entering through the third opening 124 from excessively polluting the components and chamber channels provided in the housing assembly 100.

[0108] See also Figure 11 In some embodiments, the dust box 130 can be fixedly disposed in the housing assembly 100, and the first filter screen inside the dust box 130 can be regularly replaced or the dust box 130 can be regularly cleaned to avoid the phenomenon of poor dust removal effect of the air conditioner. In other embodiments, please refer toFigure 15 , the dust collection box 130 can also be detachably arranged in the housing assembly 100, and the inside of the dust collection box 130 can be cleaned by regularly disassembling the dust collection box 130 to avoid the phenomenon of poor dust removal effect of the air conditioner. In some other embodiments, the dust collection box 130 is arranged outside the housing assembly 100, and the dust collection box 130 can directly obtain the dust generated by the dust removal assembly 40 during the dust removal process. At this time, the third opening 124 can generate negative pressure at the dust collection box 130 under the driving force of the driving motor 190, so that the dust floating out of the dust collection box 130 can enter the dust collection box 130 with the air under the action of negative pressure. The air filtered by the first filter screen 132 arranged in the dust collection box 130 flows to the fourth chamber 122 communicated with the third opening 124. Then it flows from the fourth chamber 122 to the first chamber 111, then to the second chamber 112 and the third chamber 121, and finally flows into the second area 30 through the second opening 123 communicated with the third chamber 121. Avoid the dust floating out of the dust collection box 130 from spreading to the first area 20 (i.e., the indoor area), causing the air in the first area 20 to be polluted by dust. For the convenience of description, the following takes the dust collection box 130 arranged in the housing assembly 100 and the dust collection box 130 can be detachably connected to the housing body as an example for illustration.

In one embodiment, the housing body is provided with a disassembly opening 126 on one side along the direction perpendicular to the axis of the third opening 124. In another embodiment, disassembly openings 126 are provided on both sides of the housing body that are oppositely arranged along the direction perpendicular to the axis of the third opening 124. The dust collection box 130 can be installed or disassembled in the housing assembly 100 through the disassembly opening 126. Thereby improving the convenience of cleaning the dust in the dust collection box 130.

[0110] In some embodiments, the first valve group 160 includes a baffle connected to the first housing 110, and the baffle can be used to control the opening and closing state of the first opening 113. Specifically, the baffle is connected to a third rotating part, and the third rotating part is rotatably connected to the first housing 110. In one embodiment, the baffle and the third rotating part may be integrally formed. In another embodiment, the baffle and the third rotating part may be separately formed and then connected by other connection means (such as welding, riveting, threaded connection, etc.). To facilitate the description of the position of the baffle relative to the first housing 110, it is defined that the baffle has a fourth position and a fifth position. The baffle can rotate with the third rotating part relative to the first housing 110 between the fourth position and the fifth position. When the baffle is in the fourth position, the first chamber 111 and the second chamber 112 are separated from each other, and air cannot flow from the first chamber 111 to the second chamber 112. When the baffle is in the fifth position, the first chamber 111 communicates with the second chamber 112, and at this time the baffle covers the first opening 113. At this time, the first opening 113 is in a closed state, and the air in the first chamber 111 can flow to the second chamber 112.

[0111] Please refer to Figures 1 to 6 , in some embodiments, the first housing 110 may include a side wall 114 facing the second housing 120, the second housing 120 may include a wall plate facing the first housing 110, and the side wall 114 and the wall plate may be arranged at intervals. And mounting openings may be provided at both the side wall 114 close to the first chamber 111 and the wall plate close to the fourth chamber 122. The mounting opening can be used to mount the driving fan blade of the driving motor 190. When the driving motor 190 is started, the driving fan blade connected to the driving motor 190 can rotate, so that the air in the fourth chamber 122 flows to the first chamber 111 under the drive of the driving fan blade. In some other embodiments, please refer to Figures 7 to 11 and Figure 14 , the first housing 110 includes a side wall 114 facing the second housing 120, and the second housing 120 and the side wall 114 can jointly define a third chamber 121 and a fourth chamber 122. That is, one side of the second housing 120 facing the first housing 110 can define the third chamber 121 and the fourth chamber 122 by sharing the side wall 114 of the first housing 110. Mounting openings are provided at the part of the side wall 114 located between the first chamber 111 and the fourth chamber 122, so that the driving fan blade of the driving motor 190 can be arranged between the first chamber 111 and the fourth chamber 122 through the mounting opening.

[0112] Please refer to Figure 7 and Figure 14 , in some embodiments, the housing assembly 100 further includes a second filter screen 140 disposed in the housing body, and the second filter screen 140 can be arranged at any position in the flow path where the air flow flows from the third opening 124 to the first opening 113. For the convenience of description, please refer toFigure 7 and Figure 14 , taking the second filter screen 140 disposed at the connection between the fourth chamber 122 and the first chamber 111 as an example for illustration. Please refer to Figure 8 . When the housing assembly 100 is in the first state, that is, when the air conditioner is in the fresh air mode, the air entering the housing main body from the second area 30 through the second opening 123 needs to flow through the fourth chamber 122 to the first chamber 111. At this time, the second filter screen 140 disposed at the connection between the fourth chamber 122 and the first chamber 111 can filter the air flowing from the fourth chamber 122 to the first chamber 111, and the filtered air flows into the first area 20 through the first opening 113 communicated with the first chamber 111. The quality of the air flowing from the second area 30 into the first area 20 is effectively improved.

[0113] Please refer to Figure 9 . When the housing assembly 100 is in the second state, that is, when the air conditioner is in the dust removal mode, the air entering the housing assembly 100 from the third opening 124 carries some dust floating out from the dust collection box 130. During the process of flowing from the fourth chamber 122 to the first chamber 111, the dust carried by this air will be stripped by the second filter screen 140 and temporarily stored in the second filter screen 140, so that the air flowing from the fourth chamber 122 into the first chamber 111 is filtered. The filtered air flows through the second chamber 112 communicated with the first chamber 111 to the third chamber 121, and finally is discharged to the second area 30 through the second opening 123 communicated with the third chamber 121. At this time, the setting of the second filter screen 140 can prevent the air discharged by the air conditioner in the dust removal mode from polluting the air in the second area 30.

[0114] Please refer to Figure 5 . When the housing assembly 100 is in the third state, that is, when the air conditioner is in the exhaust mode, the air entering the housing assembly 100 from the fourth opening 125 will pass through the second filter screen 140 disposed at the connection between the fourth chamber 122 and the first chamber 111 during the process of flowing from the fourth chamber 122 to the first chamber 111. The second filter screen 140 can filter the air flowing from the fourth chamber 122 to the first chamber 111, and the filtered air flows through the second chamber 112 to the third chamber 121, and then flows to the second area 30 through the second opening 123 communicated with the third chamber 121. At this time, the setting of the second filter screen 140 can prevent the air discharged by the air conditioner in the exhaust mode from polluting the air in the second area 30.

[0115] Please refer to Figure 10, when the housing assembly 100 is in the fourth state, that is, when the air conditioner is in the circulating air mode, the air in the first area 20 (i.e., the indoor area) flows into the fourth chamber 122 through the fourth opening 125, and during the process of flowing to the first chamber 111 driven by the driving motor 190, the second filter screen 140 disposed at the connection between the fourth chamber 122 and the first chamber 111 can filter and process this air, and the filtered air flows into the first area 20 (i.e., the indoor area) through the first opening 113 communicating with the first chamber 111. In this circulating air mode, the setting of the second filter screen 140 can improve the air quality in the first area 20.

[0116] In some embodiments, the first filter screen 132 and the second filter screen 140 also have the function of filtering bacteria, and the first filter screen 132 and the second filter screen 140 can adopt filtering devices with the function of filtering bacteria such as HEPA filter screens. The first filter screen 132 and the second filter screen 140 can adopt the same filtering device or different filtering devices.

[0117] Please refer to Figure 14, in some embodiments, the housing assembly 100 further includes a heating device 150, which can be arranged at an interval from the second filter screen 140, so that the air passing through the second filter screen 140 can achieve the effect of high-temperature sterilization through the heating device 150, thereby improving the quality of the air discharged by the air conditioner. In one embodiment, the heating device 150 is disposed on the wall surface of the fourth chamber 122 away from the first chamber 111. The heating device 150 can generate heat, and these heats radiate to the second filter screen 140 to make the surface of the side close to the heating device 150 present a high-temperature state. When the air flowing into the fourth chamber 122 flows to the first chamber 111 under the drive of the drive motor 190 through the second filter screen 140, the second filter screen 140 in the high-temperature state can perform high-temperature sterilization treatment on the air, thereby purifying the air discharged by the air conditioner. In some other embodiments, the heating device 150 can also improve the comfort of the air discharged by the air conditioner. Specifically, when it is necessary to increase the temperature of the air in the first area 20 to improve the comfort of the air in the first area 20, the air flowing from the fourth chamber 122 to the first chamber 111 passes through the sterilization and heating of the second filter screen 140 in the high-temperature state, and flows into the first area 20 through the first opening 113 communicating with the first chamber 111. The temperature of these airs can be higher than the temperature of the original air in the first area 20. Through the continuous sterilization, heating and discharging of the air in the first area 20 (or the second area 30) by the air conditioner to the first area 20, the temperature of the air in the first area 20 can be gradually increased, thereby improving the comfort of the air in the first area 20. In still some other embodiments, the heating device 150 can also be integrated with the second filter screen 140, that is, the second filter screen 140 can have a heating function, so as to achieve the effects of high-temperature sterilization and heating the air.

[0118] In some embodiments, the housing assembly 100 provided by the present invention can be used for a ventilation module, and the ventilation module can make the air in the first area 20 and the air in the second area 30 flow through each other. The ventilation module includes a drive motor 190. In some embodiments, the ventilation module can be used for an air conditioner. The air conditioner includes a dust removal assembly 40, and the ventilation module can collect the dust generated during the dust removal process of the dust removal assembly 40, avoiding the dust falling from the dust removal assembly 40 floating into the first area 20 and polluting the air in the first area 20. Among them, the housing assembly 100 includes a housing body, a first valve group 160 and a second valve group 170. Please refer to Figure 20, the housing body can define an annular chamber 50, and a connection structure 51 capable of connecting the driving motor 190 is provided in the annular chamber 50. The driving motor 190 can drive the air in the annular chamber 50 to move along a first circumferential direction. The first circumferential direction can be the direction in which the driving motor 190 drives the air flow, that is, the air flow flows from the position of the third opening 124 in the annular chamber along the annular chamber 50 to the position of the first opening 113 in the annular chamber, from the position of the first opening 113 in the annular chamber to the position of the second opening 123 in the annular chamber, and from the position of the second opening 123 in the annular chamber to the position of the third opening 124 in the annular chamber. The housing body is provided with a first opening 113, a second opening 123, and a third opening 124 that are respectively communicated with the annular chamber 50. The first opening 113 can be communicated with the first region 20, the second opening 123 can be communicated with the second region 30, and the third opening 124 can be communicated with the first region 20 and can obtain the dust generated by the dust removal assembly 40. The first valve group 160 and the second valve group 170 are both arranged to be able to open or close the annular chamber 50. Along the first circumferential direction, the first valve group 160 is arranged between the first opening 113 and the second opening 123, the second valve group 170 is arranged between the second opening 123 and the third opening 124, and the connection structure 51 connecting the driving motor 190 is arranged between the third opening 124 and the first opening 113.

[0119] In some embodiments, please refer to Figure 20 , the specific shape of the annular chamber 50 can be circular. In some other embodiments, the specific shape of the annular chamber 50 can be any shape, as long as the air flow inside the chamber can circulate in one direction. That is, when the air flow at the starting point position circulates along the first circumferential direction, it can return to the starting point position, then this chamber is the annular chamber 50. Refer to Figure 1 , Figure 8 , Figure 14 and Figure 15 , Figure 20 The chambers in the corresponding embodiments are also the annular chamber 50.

[0120] In a specific embodiment, the first opening 113 may be the air outlet of the air conditioner within the first region 20, that is, the first opening 113 may be the air outlet of the air conditioner in the fresh air mode and the circulating air mode. The second opening 123 may be the air outlet / inlet of the air conditioner within the second region 30 (i.e., the second opening 123 can serve both as the air outlet of the air conditioner within the second region 30 and as the air inlet of the air conditioner within the second region 30), that is, the second opening 123 may be the air inlet of the air conditioner in the fresh air mode and may also be the air outlet of the air conditioner in the exhaust mode. The third opening 124 may be the air inlet of the air conditioner within the first region 20, that is, the third opening 124 may be the air inlet of the air conditioner in the dust removal mode and may also be the air inlet of the air conditioner in the exhaust mode.

[0121] Please refer to Figure 16 and Figure 17 , when the air conditioner is in the fresh air mode, the first valve group 160 is in the closed state, and the second valve group 170 is in the open state. The air within the second region 30 flows into the annular chamber 50 through the second opening 123 under the drive of the drive motor 190, and flows towards the first opening 113 through the open second valve group 170, and then flows into the first region 20 through the first opening 113. In this fresh air mode, since the first valve group 160 is in the closed state, the part of the annular chamber 50 between the first opening 113 and the second opening 123 is not connected. The gas flowing into the annular chamber 50 from the second opening 123 can only flow towards the first opening 113 through the second valve group 170.

[0122] Please refer to Figure 14 and Figure 15 , when the air conditioner is in the dust removal mode, the first valve group 160 is in the open state to connect the part of the annular chamber 50 between the first opening 113 and the second opening 123, and the second valve group 170 is in the closed state to disconnect the part of the annular chamber 50 between the second opening 123 and the third opening 124. The air within the first region 20 flows into the annular chamber 50 through the third opening 124 under the drive of the drive motor 190, and flows towards the second opening 123 through the open first valve group 160, and then flows into the second region 30 through the second opening 123.

[0123] In some embodiments, the first valve group 160 is configured such that when it is in the open state, the first opening 113 can be closed through this first valve group 160. Please refer to Figure 15 . In some other embodiments, the first opening 113 can also be closed by setting other structures. Please refer to Figure 18 and Figure 15, when the air conditioner is in the exhaust mode, the second valve group 170 and the first opening 113 are both in the closed state, and the first valve group 160 and the third opening 124 are both in the open state. In some other embodiments, the housing assembly 100 further includes a third valve group 180 configured to be able to open or close the third opening 124. Please refer to Figure 16 and Figure 17 , when the air conditioner is in the fresh air mode, the first valve group 160 and the third opening 124 are both in the closed state, while the second valve group 170 and the first opening 113 are both in the open state.

[0124] The second aspect of the present invention further provides a ventilation module, which includes the housing assembly 100 described in any of the above embodiments. The ventilation module further includes a driving motor 190, which can provide driving force for the ventilation module so that the air in the first area 20 and the second area 30 can flow through the ventilation module.

[0125] The third aspect of the present invention further provides an air conditioner, which includes the ventilation module described in the above embodiments. Please refer to Figure 19 . The air conditioner further includes a dust removal component 40. The ventilation function of the air conditioner can be switched between the fresh air mode, the dust removal mode, the exhaust mode and the circulating air mode. Among them, when the air conditioner is in the dust removal mode, the ventilation module can collect and process the dust generated during the dust removal process of the dust removal component 40, preventing the dust separated from the dust removal component 40 from floating into the first area 20 and affecting the air quality in the first area 20. The setting of the ventilation module enables the air conditioner to save the internal space of the air conditioner without additionally increasing a dedicated dust removal channel for conducting dust. And the power for driving the dust to be discharged outdoors is provided by the driving motor 190 of the ventilation module, without additionally increasing a driving motor, reducing the number of motors of the air conditioner and lowering the material cost of the air conditioner.
