[0038] Compared with the prior art, the beneficial effects of the utility model are:

[0039] In the technical solution of the utility model, the shell assembly is used for the ventilation module, and the ventilation module is used for the air conditioner. The shell assembly includes a shell body, and the shell body is provided with a first opening, a second opening and a third opening. The first opening and the third opening can be connected to the indoor (i.e., the first area), and the second opening can be connected to the outdoor (i.e., the second area). In particular, the third opening is suitable for obtaining dust generated by the dust removal assembly of the air conditioner during the dust removal process. In the dust removal mode of the air conditioner (when the shell assembly is in the second state), the driving motor in the shell assembly drives the air in the room to enter the shell body through the third opening, and is guided out to the outdoor through the second opening. In the process of air being introduced into the third opening, a pressure difference can be generated at the dust removal assembly to generate suction, and the suction can prevent the dust generated by the dust removal assembly during the dust removal process from floating into the room 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, so there is no need to add an additional dust removal channel dedicated to conducting dust, saving the internal space of the air conditioner. In addition, the power for driving the dust to be discharged outdoors is provided by the driving motor of the ventilation module, and there is no need to add an additional driving motor, which reduces the number of motors of the air conditioner and reduces the material cost of the air conditioner.

[0040] Furthermore, in the utility model, in the fresh air mode of the air conditioner (when the shell assembly is in the first state), the driving motor in the shell assembly drives the outdoor air to enter the shell body through the second opening, and guide the shell body out of the room through the first opening. In addition, the shell assembly is configured to make the driving direction of the driving motor the same in the first state and the second state. In this solution, since the driving direction of the driving motor is the same in the two states of the shell assembly, the fan blades of the driving motor do not need to switch the rotation direction (in the related art, since the airflow directions in the two states are opposite, the fan blades of the motor need to switch the rotation direction), so that the fan blades can always maintain the best driving efficiency (in the related art, the fan blades can only maintain a high driving efficiency when rotating forward, and the driving efficiency is relatively low when reversing).

[0041] Furthermore, in the utility model, since the driving direction of the driving motor of the shell assembly remains unchanged in the first state and the second state, the ventilation module having the shell 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 ventilation mode is switched by making the driving motor rotate forward and reverse, for example, when the ventilation module is switched from the fresh air mode to the dust removal mode, the driving motor needs to switch from forward to reverse, and the switching process takes a long time. When the switching process is set too short, the driving motor decelerates in a short time and accelerates in the reverse direction, which will cause a short circuit, which will reduce the service life of the driving motor and even burn the motor in severe cases.

[0082] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0083] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0084] The ventilation function modes of the air conditioner usually include fresh air mode, dust removal mode, exhaust mode and circulating air mode. The fresh air mode refers to the air being drawn into the room through the air conditioner. The dust removal mode refers to the dust removal of the filter installed in the air conditioner. During the dust removal process, in order to prevent the dust separated from the filter from drifting into the indoor air, it is usually necessary to set a dust removal channel to guide the dust separated from the filter to the outside. The exhaust mode refers to the air being drawn out to the outside through the air conditioner. The circulating air mode refers to the air being drawn into the air conditioner, and then discharged to the room after being processed by the air conditioner. In order to realize the switching of the ventilation function of the air conditioner, the air conditioner usually includes multiple drive motors, each of which can drive each function mode. However, this setting method greatly increases the production cost of the air conditioner.

[0085] Therefore, the applicant considers to reuse the drive motors in the fresh air mode, dust removal mode, exhaust mode and circulating air mode, that is, to integrate the driving modes of each functional mode into the drive motor, thereby reducing the number of drive motors of the air conditioner and reducing the material cost of the air conditioner. Since the air flow direction in the fresh air mode (from the outside to the indoor) is opposite to the air flow direction in the dust removal mode (from the indoor to the outdoor), it is necessary to change the rotation direction of the drive motor to facilitate the switching of the ventilation function mode of the air conditioner. However, the applicant finds that the fan blade connected to the drive motor can only maintain the best driving efficiency in a certain rotation direction (i.e., the drive motor is forward or reverse) due to its own structural design. In addition, when the air conditioner is switched from the fresh air mode to the dust removal mode, the drive motor needs to switch its rotation direction. The following takes the switching of the drive motor from forward to reverse as an example. When the rotation direction of the drive motor is switched, due to the existence of the rotation 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 of the reverse rotation of the drive motor will be used to offset the inertia of the forward rotation, resulting in energy loss. In addition, deceleration and reverse acceleration of the drive motor in a short period of time will cause a short circuit, which will reduce the service life of the drive motor and may even cause the drive motor to burn out in severe cases.

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

[0087] For this reason, please see Figures 1 to 20 The first aspect of the utility model provides a housing assembly 100, which is used in a ventilation module, and the ventilation module is used in an air conditioner. Figure 1 The shell assembly 100 includes a shell body, and the shell 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 be connected to the first area 20, and the second opening 123 can be connected to the second area 30. In one embodiment, the first area 20 can be indoors, and the second area 30 can be outdoors. In another embodiment, the first area 20 can be a room indoors, and the second area 30 can be another room indoors. For ease of description, the following description is taken as an example that the first area 20 is indoors and the second area 30 is outdoors. In particular, the third opening 124 is suitable for connecting to the first area 20 and for circulating the airflow of dust generated by the 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 a fresh air mode. Figure 2When the housing assembly 100 is in the second state, the air conditioner may be in a dust removal mode, see Figure 3 The first opening 113 can be an air outlet of the air conditioner indoors (i.e., the first area 20), the second opening 123 can be an air outlet / air inlet of the air conditioner outdoors (i.e., the second area 30) (when air needs to be exhausted from indoors to outdoors, the second opening 123 is the air outlet of the air conditioner outdoors, and when air needs to be taken in from outdoors to indoors, the second opening 123 is the air inlet of the air conditioner outdoors), and the third opening 124 can be a dust removal port of the air conditioner. When the shell assembly 100 is in the first state (i.e., the air conditioner is in the fresh air mode), the driving motor 190 drives the air outdoors (i.e., the second area 30) to enter the shell body through the second opening 123, and is guided out to the indoor (i.e., the first area 20) through the first opening 113. When the shell assembly 100 is in the second state (i.e., the air conditioner is in the dust removal mode), the driving motor 190 drives the air in the room (i.e., the first area 20) to enter the shell 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 suction can prevent the dust generated by the dust removal assembly 40 during the dust removal process from drifting into the room 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 add an additional dust removal channel dedicated to conducting dust, thereby saving the internal space of the air conditioner. Moreover, in the present utility model, the dust removal mode and the fresh air mode of the air conditioner are driven by the same driving motor 190, and there is no need to add an additional driving motor 190 to the dust removal mode of the air conditioner, thereby reducing the number of motors of the air conditioner and reducing the material cost of the air conditioner. When the shell assembly 100 is in the first state, the driving direction of the driving motor 190 is the same as the driving direction of the driving motor 190 when the shell assembly 100 is in the second state, that is, when the air conditioner switches the functional mode, the driving direction of the driving motor 190 remains unchanged, which effectively improves the conversion efficiency of the driving motor 190 and on the other hand also improves the service life of the driving motor 190.

[0089] See also Figures 1 to 18In 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, which can control the mutual connection or separation of the first chamber 111 and the second chamber 112 by opening or closing, and some of the 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, and when the valve is in a closed state, the first chamber 111 can be separated from the second chamber 112, and the first opening 113 can be connected to the first chamber 111. When the valve is in an open state, the first chamber 111 can be connected to the second chamber 112, and the first opening 113 is closed by the valve, so that the first opening 113 can not be connected to the first chamber 111. For ease of description, the following description is taken as an example that the first valve group 160 is a single valve. The first shell 110 defines a first chamber 111 and a second chamber 112, and the first opening 113 can communicate with the first chamber 111. Figure 1 and Figure 3 The first valve group 160 is disposed in the first shell 110 and can separate or connect the first chamber 111 and the second chamber 112. Figure 1 When the first valve assembly 160 separates the first chamber 111 and the second chamber 112, the first opening 113 can be connected to the first chamber 111. Figure 3 When the first valve group 160 is in communication with 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 the first chamber 111 and is not in communication. 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 state of the first opening 113 can be controlled by setting other valve groups.

[0090] See also Figure 1 and Figure 2 The second shell 120 defines a third chamber 121 and a fourth chamber 122. The second valve group 170 is disposed in the second shell 120 and can separate or connect the third chamber 121 and the fourth chamber 122. In some embodiments, see Figure 1, the third chamber 121 can always be connected to the second chamber 112, and the second opening 123 can always be connected to the third chamber 121. In other embodiments, a valve can be further provided between the third chamber 121 and the second chamber 112, and a valve can be further provided at the second opening 123. When the air conditioner is in operation, 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 be connected to the third chamber 121, and the second opening 123 can be connected to the third chamber 121. When the air conditioner is in shutdown or the second opening 123 does not need to discharge air into the second area 30, the valve provided 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 being poured into the air conditioner through the second opening 123. For ease of description, the following description is made by taking the third chamber 121 always being connected to the second chamber 112 and the second opening 123 always being connected to the third chamber 121 as an example. The third opening 124 can be connected to the fourth chamber 122. Figure 1 and Figure 3 The third valve group 180 is disposed in the fourth chamber 122 and is capable of opening or closing the third opening 124 , so that the third opening 124 can be connected to or separated from the fourth chamber 122 .

[0091] In one embodiment, the third valve group 180 may be a combination of multiple valves, which can control the interconnection or separation of the third opening 124 and the fourth chamber 122 by opening or closing. In another embodiment, the third valve group 180 is composed of a single valve, and when the valve is in a closed state, the third opening 124 can be separated from the fourth chamber 122. When the valve is in an open state, the third opening 124 can be connected to the fourth chamber 122, so that the first area 20 connected to the third opening 124 can be connected to the fourth chamber 122. For ease of description, the third valve group 180 is described below as a single valve.

[0092] See also Figure 6In some embodiments, the drive motor 190 can be arranged between the fourth chamber 122 and the first chamber 111. In other embodiments, the drive motor 190 can be arranged at any position of the housing assembly 100, and the drive blade part of the drive motor 190 is arranged between the fourth chamber 122 and the first chamber 111. In the utility model, by arranging the first valve group 160, the second valve group 170 and the third valve group 180 in the shell body, the first chamber 111, the second chamber 112, the third chamber 121 and the fourth chamber 122 can be interconnected or separated. And the drive motor 190 arranged between the fourth chamber 122 and the first chamber 111 can drive the air in the fourth chamber 122 to flow to the first chamber 111, so that the air entering the shell body in different functional modes can reuse these chambers in different modes, saving the space for setting the dust removal channel in the dust removal mode of the air conditioner.

[0093] See also Figure 2 , Fig.16 as well as Fig.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 area 30 flows into the housing assembly 100 through the second opening 123 and flows into the first area 20 through the first opening 113. Figure 2, the second valve group 170 located between the third chamber 121 and the fourth chamber 122 is opened to connect the third chamber 121 with the fourth chamber 122. Since the third chamber 121 is connected to the second area 30 (i.e., outdoors), 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 is closed to separate 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 is closed to close the third opening 124. The driving 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 can enter the housing assembly 100 through the second opening 123, and flow from the third chamber 121 to the fourth chamber 122, and 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. In 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 a closed state, the air flowing from the third chamber 121 to the second chamber 112 cannot flow directly to the first chamber 111. The air flow path in the fresh air mode is limited to prevent the air from moving in the housing assembly 100. Furthermore, since the third opening 124 can obtain the dust generated by the dust removal assembly 40, at this time, the third valve group 180 is in a closed state, so that the third opening 124 is in a closed state, that is, the third opening 124 is not connected to the fourth chamber 122. This prevents the air entering the housing assembly 100 from flowing to the first area 20 through the third opening 124, thereby preventing the dust generated by the dust removal assembly 40 from being blown into the first area 20 (i.e., indoors), causing air pollution.

[0094] See also Figure 3 , Fig.14 as well as Fig.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 driven by the driving motor 190, and flows to the second area 30 through the second opening 123. 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 be connected, and the first valve group 160 can close the first opening 113. Since the third chamber 121 is connected to the second area 30 (i.e., outdoors), the first chamber 111, the second chamber 112, the third chamber 121 and the second area 30 can be connected to each other. The third valve group 180 set in the fourth chamber 122 is opened to open the third opening 124, so that the third opening 124 is connected to the fourth chamber 122, and then the fourth chamber 122 can be connected to the first area 20 (i.e., indoors). The second valve group 170 is in a closed state, so that the third chamber 121 and the fourth chamber 122 are separated and not connected. The driving 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 first area 20 flows to the fourth chamber 122 through the third opening 124, and then flows from the fourth chamber 122 to the first chamber 111 under the drive of the driving motor 190. Since the first opening 113 is closed by the first valve group 160, the air flow cannot flow out from the first opening 113, so the air flow can only flow to the second chamber 112 through the first valve group 160 in the open state, and then flow to the third chamber 121 connected to the second chamber 112. Since the second valve group 170 is in a closed state, the third chamber 121 is not connected to the fourth chamber 122, so the air flowing into the third chamber 121 flows to the second area 30 (i.e., outdoors) through the second opening 123. The states of the first valve group 160 , the second valve group 170 and the third valve group 180 limit the flow path of the air in the dust removal mode, thereby preventing the dust-carrying air from freely moving in the housing assembly 100 and contaminating other components in the housing assembly 100 .

[0095] See also Figure 2 When the housing assembly 100 is in the first state, the airflow direction is from the second area 30 to the first area 20. Figure 3 , when the housing assembly 100 is in the second state, the airflow flows from the first area 20 to the second area 30, that is, the airflow in the two states is opposite to the flow direction between the first area 20 and the second area 30. In the present invention, by setting the first valve group 160 and the second valve group 170 in the housing assembly 100, the housing assembly 100 is in different states and the opening and closing states of the first valve group 160 and the second valve group 170 are controlled, so that no matter the airflow flows from the first area 20 to the second area 30 or from the second area 30 to the first area 20, the airflow path has a process from the fourth chamber 122 to the first chamber 111. Please refer to Figure 6The drive motor 190 is disposed between the fourth chamber 122 and the first chamber 111, so that the drive motor 190 only needs to be driven in the direction from the fourth chamber 122 to the first chamber 111. Therefore, the fan blades of the drive motor 190 do not need to switch the rotation direction, so that the drive motor 190 can always maintain the best driving efficiency and increase the service life of the drive motor 190. For details, please refer to Figure 2 When the housing assembly 100 is in the first state, that is, the air conditioner is in the fresh air mode, the airflow path is from the second area 30 to the third chamber 121 through the second opening 123, to the fourth chamber 122 through the second valve group 170, and then to the first chamber 111 driven by the driving motor 190, and finally to the first area 20 through the first opening 113. 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 air flow path is from the first area 20 to the fourth chamber 122 through the third opening 124, and under the drive of the drive motor 190, it flows to the first chamber 111, flows into the second chamber 112 through the first valve group 160, and then flows into the third chamber 121 connected to the second chamber 112, and finally flows into the second area 30 through the second opening 123 connected to the third chamber 121.

[0096] See also Figure 5 , Fig.18 as well as Fig.15 In some embodiments, the ventilation function mode of the air conditioner may also include an exhaust mode. To prevent the air entering the housing assembly 100 from being affected by the dust generated by the dust removal assembly 40 in this mode, please refer to Figure 5 In some embodiments, the shell body is further provided with a fourth opening 125. The fourth opening 125 is connected to the fourth chamber 122, and the fourth opening 125 can be connected to the first area 20 (ie, the room). The shell assembly 100 also includes a third state. Figure 5 When the housing assembly 100 is in the third state, please refer to Fig.18 as well as Fig.15, the air conditioner having the shell assembly 100 is in exhaust mode. When the shell assembly 100 is in the third state, the drive motor 190 can drive the air in the first area 20 to enter the shell body through the fourth opening 125, and be exported to the second area 30 through the second opening 123. The driving direction of the drive motor 190 of the shell assembly 100 in the third state is the same as the driving direction of the drive motor 190 of the shell 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 also configured to be able to open or close the fourth opening 125. For ease of description, the following is an example of using the third valve group 180 to control the opening and closing state of the fourth opening 125.

[0097] See also Figure 5 In a specific embodiment, when the housing assembly 100 is in the third state, that is, when the air conditioner having the housing assembly 100 is in the exhaust mode, the first valve group 160 is opened so that the first chamber 111 can be connected to 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 is not connected. The third valve group 180 is configured to open the fourth opening 125 and close the third opening 124 so that the first area 20 (i.e., the room) can be connected to the fourth chamber 122 through the fourth opening 125. The driving 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 area 20 can flow into the fourth chamber 122 through the fourth opening 125, and enter the first chamber 111 under the drive of the driving 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 to the second chamber 112 through the first valve group 160, and then flow to the third chamber 121 connected to the second chamber 112. 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 area 30 (i.e., outdoors) through the second opening 123. In this exhaust mode, since the second valve group 170 is in a closed state, the third chamber 121 and the fourth chamber 122 are separated, so that the drive motor 190 will not affect the air in the second area 30 (i.e., outdoors) connected to the third chamber 121, and the exhaust efficiency is effectively improved.

[0098] See also Figure 4 , Fig.18 as well as Fig.17In other embodiments, the ventilation function mode of the air conditioner may also include a circulating wind 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. Figure 4 When the housing assembly 100 is in the fourth state, the air conditioner having the housing assembly 100 is in the circulating wind mode. When the housing assembly 100 is in the fourth state, the driving motor 190 can drive the air in the first area 20 to enter the housing body through the fourth opening 125, and be guided out to the first area 20 through the first opening 113. The driving direction of the driving motor 190 of the housing assembly 100 in the fourth state is the same as the driving direction of the driving motor 190 of the housing assembly 100 in the first state.

[0099] See also Figure 4 , Fig.18 as well as Fig.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 so that the first chamber 111 is separated from the second chamber 112 and is not connected, and the first opening 113 is in an open state so that the first opening 113 is connected to the first chamber 111, and then the first chamber 111 is connected to the first area 20 (i.e., indoors) through the first opening 113. The second valve group 170 is closed so that the third chamber 121 is separated 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 is connected to the fourth chamber 122, and then the fourth chamber 122 is connected to the first area 20 (i.e., indoors) through the fourth opening 125. The third opening 124 is closed so that the third opening 124 is separated from the fourth chamber 122. The driving motor 190 is started to make the air in the fourth chamber 122 and the first chamber 111 have a pressure difference, so that the air in the first area 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 through the drive of the driving motor 190. 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 area 20 (i.e., indoors) through the first opening 113. The circulating air mode of the air conditioner is conducive to improving the cooling and heating efficiency of the air conditioner. When the housing assembly 100 is in the fourth state and the air conditioner is in the circulating air mode, the first valve group 160 in a closed state can prevent the air entering the first chamber 111 from flowing to the second chamber 112, and then flowing to the second area 30 (i.e., outdoors) through the third chamber 121. The second valve assembly 170 in the closed state can prevent the air in the second area 30 (ie, outdoors) from being driven by the driving motor 190 to enter the housing assembly 100, thereby reducing the circulation efficiency of the circulating wind mode of the air conditioner.

[0100] See also Figure 2 , Figure 6 as well as Fig.16 In some embodiments, the third valve group 180 can also close the third opening 124 and the fourth opening 125 at the same time. In other embodiments, the third valve group 180 is used to control the opening and closing state of the third opening 124, and the opening and closing state 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 state of the fourth opening 125. For ease of description, the following is an example of using the third valve group 180 to control the opening and closing state of the third opening 124 and the fourth opening 125. When the third valve group 180 closes the third opening 124 and the fourth opening 125 at the same time, 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 a closed state to separate the first chamber 111 from the second chamber 112, and the first opening 113 is in an open state to connect the first chamber 111 to the first area 20 (i.e., indoors). The second valve group 170 is in an open state, so that the third chamber 121 is connected to the fourth chamber 122, and the fourth chamber 122 can be connected to the second area 30 (i.e., outdoors) through the third chamber 121. The third valve group 180 is in a fully closed state, so that the third opening 124 and the fourth opening 125 are both closed, so that the third opening 124 and the fourth opening 125 can be separated from the fourth chamber 122. The driving 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 second area 30 (i.e., outdoors) 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 driving motor 190, and finally flow into the first area 20 (i.e., indoors) through the first opening 113.

[0101] See also Figure 3 , Fig. 9 , Fig.11 as well as Fig.14In some embodiments, the third valve group 180 can also close only the fourth opening 125 and leave the third opening 124 in an open state. 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 is opened to connect the first chamber 111 to the second chamber 112, and the first valve group 160 can close the first opening 113, so that the first area 20 (i.e., indoor) is separated from the first chamber 111, and the air carrying dust is prevented from flowing into the first area 20 (i.e., indoor) from the first opening 113. The second valve group 170 is closed 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., indoor) from entering the housing assembly 100 when the drive motor 190 is driven, affecting 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 driving 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 first area 20 (i.e., indoors) flows to the fourth chamber 122 through the third opening 124, and is driven to the first chamber 111 by the driving motor 190, and then flows to the second chamber 112, and flows to the second area 30 (i.e., outdoors) through the second opening 123 connected to the third chamber 121. In this dust removal mode, the fourth opening 125 is closed to prevent the dust carried by the air flowing in through the third opening 124 from flowing into the first area 20 (i.e., indoors) through the fourth opening 125, causing air pollution in the first area 20.

[0102] See also Figures 1 to 19In some embodiments, in order to effectively realize the control of the opening and closing state of the third opening 124 and the fourth opening 125, the third opening 124 and the fourth opening 125 can be distributed along the circumference of the first rotation axis. The third valve group 180 includes a first rotating portion 182, and the first rotating portion 182 is configured to be able to rotate around the first rotation axis. The specific shape of the first rotating portion 182 can be a long arc wall structure, or a fan-shaped structure or other structure that can rotate around the first rotation axis. In order to facilitate the description of the position state relationship of the third valve group 180, the first rotating portion 182 is defined as having a first position, a second position and a third position. Among them, during the rotation of the first rotating portion 182 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. When the first rotating portion 182 rotates to the second position, the first rotating portion 182 can rotate around the first rotating 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. When the first rotating portion 182 rotates to the third position, the first rotating portion 182 can rotate around the first rotating 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 part, which can be a plate-shaped structure, a spherical structure, or an arc wall structure, or other structures that can achieve blocking and opening of the third chamber 121 and the fourth chamber 122. The second rotating part can rotate around the second rotation axis to open or close the second valve group 170, so that the third chamber 121 and the fourth chamber 122 can be connected or separated. Similarly, the first valve group 160 can have a third rotating part, which can be a plate-shaped structure, a spherical structure, or other structures that can achieve blocking and opening of the first chamber 111 and the second chamber 112, such as an arc wall structure. The third rotating part can rotate around the third rotation axis to open or close the first valve group 160, so that the first chamber 111 and the second chamber 112 can be connected or separated.

[0104] See also 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 at the same time, the third valve group 180 further defines a valve cavity 181. Figure 8The first rotating portion 182 is disposed in the valve cavity 181, and the third opening 124 and the fourth opening 125 are both connected to the valve cavity 181. The valve cavity 181 is also provided with a fifth opening 1811 connected to the fourth chamber 122. 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 portion 182 can move along the inner wall of the valve cavity 181. Fig.10 When the first rotating portion 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 is connected to the fourth chamber 122 through the fifth opening 1811. Fig. 9 When the first rotating portion 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 be connected to the fourth chamber 122 through the fifth opening 1811. Figure 8 When the first rotating portion 182 is at 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 be provided with a control motor 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 be automatically changed with the switching of the functional mode of the air conditioner, and the control motor 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 support force for the opening state and the closing 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 opening state or the closing state. For the convenience of description, the first position, the second position and the third position of the third valve group 180 are used as an example for description. 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 is separated from the first position and rotates toward 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 remain in the second position, so that the third opening 124 can remain in an open state. When the first rotating part 182 needs to switch from the second position to the third position, the control motor drives the first rotating part 182 to rotate around the first rotating axis, so that the first rotating part 182 is separated from the second position and rotates toward 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 remain in the third position, so that the third opening 124 and the fourth opening 125 can remain in a closed state.

[0106] See also Figures 11 to 19 In some embodiments, the housing assembly 100 further includes a dust box 130 disposed in the housing body, and the dust box 130 can collect dust entering the housing body through the third opening 124. Fig.11 The dust box 130 can be disposed in the passage connecting the third opening 124 to the fourth cavity, and the dust box 130 is provided with a dust collecting port 1311 facing the third opening 124. Fig.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 Fig.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 Fig.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 to Fig.15 The dust box 130 can also be detachably arranged in the housing assembly 100, and the dust box 130 can be regularly removed to clean the inside thereof, so as to avoid the phenomenon that the dust removal effect of the air conditioner is poor. In some other embodiments, the dust box 130 is arranged outside the housing assembly 100, and the dust 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 be used to generate negative pressure at the dust box 130 under the action of the driving force of the driving motor 190, so that the dust floating out of the dust box 130 can enter the dust box 130 with the air under the action of negative pressure, and the air filtered by the first filter 132 arranged in the dust box 130 flows to the fourth chamber 122 connected to the third opening 124. Then the air flows from the fourth chamber 122 to the first chamber 111, and then to the second chamber 112 and the third chamber 121, and finally flows into the second area 30 through the second opening 123 connected to the third chamber 121. The dust from the dust box 130 is prevented from being dispersed to the first area 20 (i.e., indoors), causing the air in the first area 20 to be polluted by dust. For ease of description, the following description is based on an example in which the dust box 130 is disposed in the housing assembly 100 and the dust box 130 can be detachably connected to the housing body.

[0109] See also Fig.15 In order to facilitate the disassembly of the dust box 130, in some embodiments, the shell body is provided with a disassembly opening 126. In one embodiment, the shell body is provided with a disassembly opening 126 on one side along a direction perpendicular to the axis of the third opening 124. In another embodiment, the shell body is provided with disassembly openings 126 on both sides of the shell body that are oppositely arranged along a direction perpendicular to the axis of the third opening 124. The dust box 130 can be installed or disassembled in the housing assembly 100 through the disassembly opening 126. This improves the convenience of cleaning the dust in the dust box 130.

[0110] In some embodiments, the first valve group 160 includes a baffle connected to the first shell 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 the third rotating part, and the third rotating part is rotatably connected to the first shell 110. In one embodiment, the baffle and the third rotating part can be integrally formed. In another embodiment, the baffle and the third rotating part can be formed separately and then connected by other connection methods (such as welding, riveting, threaded connection, etc.). In order to facilitate the description of the position of the baffle relative to the first shell 110, the baffle is defined to have a fourth position and a fifth position. The baffle can rotate between the fourth position and the fifth position relative to the first shell 110 with the third rotating part. 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 is connected to the second chamber 112, and 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] See also Figures 1 to 6 In some embodiments, the first shell 110 may include a side wall 114 facing the second shell 120, and the second shell 120 may include a wall panel facing the first shell 110, and the side wall 114 and the wall panel may be arranged at intervals. And installation openings may be provided at the side wall 114 near the first chamber 111 and at the wall panel near the fourth chamber 122. The installation openings can be used to install the drive blades of the drive motor 190. When the drive motor 190 is started, the drive blades connected to the drive motor 190 can rotate so that the air in the fourth chamber 122 flows to the first chamber 111 under the drive of the drive blades. In other embodiments, please refer to Figures 7 to 11 as well as Fig.14 The first shell 110 includes a side wall 114 facing the second shell 120, and the second shell 120 and the side wall 114 can jointly define a third chamber 121 and a fourth chamber 122. That is, the side of the second shell 120 facing the first shell 110 can define the third chamber 121 and the fourth chamber 122 by sharing the side wall 114 of the first shell 110. The part of the side wall 114 located in the first chamber 111 and the fourth chamber 122 is provided with an installation opening, so that the driving blades of the driving motor 190 can be arranged between the first chamber 111 and the fourth chamber 122 through the installation opening.

[0112] See also Figure 7 and Fig.14 In some embodiments, the housing assembly 100 further includes a second filter screen 140 disposed in the housing body. The second filter screen 140 can be arranged at any position in the flow path of the airflow from the third opening 124 to the first opening 113. For ease of description, please refer to Figure 7 as well as Fig.14 The following description will be made by taking the second filter screen 140 disposed at the connecting portion between the fourth chamber 122 and the first chamber 111 as an example. 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 body from the second area 30 through the second opening 123 needs to flow to the first chamber 111 through the fourth chamber 122. At this time, the second filter 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 connected to the first chamber 111. The quality of the air flowing from the second area 30 into the first area 20 is effectively improved.

[0113] See also Fig. 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 through the third opening 124 carries part of the dust floating out from the dust box 130. In the process of the air flowing from the fourth chamber 122 to the first chamber 111, the dust carried by the air will be stripped by the second filter 140 and temporarily stored in the second filter 140, so that the air flowing from the fourth chamber 122 to the first chamber 111 is filtered. The filtered air flows to the third chamber 121 through the second chamber 112 connected to the first chamber 111, and is finally discharged to the second area 30 through the second opening 123 connected to the third chamber 121. At this time, the setting of the second filter 140 can prevent the air discharged from the air conditioner in the dust removal mode from polluting the air in the second area 30.

[0114] See also 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 through the fourth opening 125 will pass through the second filter 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 140 can filter the air flowing from the fourth chamber 122 to the first chamber 111, and the filtered air flows to the third chamber 121 through the second chamber 112, and then flows to the second area 30 through the second opening 123 connected to the third chamber 121. At this time, the provision of the second filter 140 can prevent the air discharged from the air conditioner in the exhaust mode from polluting the air in the second area 30.

[0115] See also Fig.10When the housing assembly 100 is in the fourth state, that is, when the air conditioner is in the circulating wind mode, the air in the first area 20 (i.e., the room) flows into the fourth chamber 122 from the fourth opening 125, and in the process of flowing to the first chamber 111 driven by the driving motor 190, the second filter 140 disposed at the connection between the fourth chamber 122 and the first chamber 111 can filter the air, and the filtered air flows into the first area 20 (i.e., the room) through the first opening 113 connected to the first chamber 111. In this circulating wind mode, the second filter 140 can improve the air quality in the first area 20.

[0116] In some embodiments, the first filter 132 and the second filter 140 also have the function of filtering bacteria, and the first filter 132 and the second filter 140 can use a filter device that has the function of filtering bacteria, such as a HEPA filter. The first filter 132 and the second filter 140 can use the same filter device or different filter devices.

[0117] See also Fig.14In some embodiments, the housing assembly 100 further includes a heating device 150, and the heating device 150 and the second filter 140 can be arranged at intervals, so that the air passing through the second filter 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 arranged on the wall surface of the fourth chamber 122 on the side away from the first chamber 111. The heating device 150 can generate heat, which is radiated to the second filter 140 so that the surface of the side close to the heating device 150 is in a high-temperature state. When the air flowing into the fourth chamber 122 flows to the first chamber 111 through the second filter 140 under the drive of the drive motor 190, the second filter 140 in a high-temperature state can perform high-temperature sterilization on the air, thereby purifying the air discharged by the air conditioner. In 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 second filter 140 in a high temperature state, sterilized and heated, and then flows into the first area 20 through the first opening 113 connected to the first chamber 111. The temperature of the air can be higher than the temperature of the original air in the first area 20. The air in the first area 20 (or the second area 30) is continuously sterilized, heated and discharged to the first area 20 by the air conditioner, so that 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 some other embodiments, the heating device 150 can also be integrated with the second filter 140, that is, the second filter 140 can have a heating function, so as to achieve the effect of high-temperature sterilization and heating of the air.

The first valve group 160 and the second valve group 170 are configured to be able to open or close the annular chamber 50. Along the first circumferential direction, the first valve group 160 is disposed between the first opening 113 and the second opening 123, the second valve group 170 is disposed between the second opening 123 and the third opening 124, and the connecting structure 51 connecting the drive motor 190 is disposed between the third opening 124 and the first opening 113.

[0119] In some embodiments, see Fig. 20 , the specific shape of the annular chamber 50 can be a circular ring. In other embodiments, the specific shape of the annular chamber 50 can be any shape, as long as the airflow inside the chamber can circulate in one direction. That is, if the airflow at the starting point can return to the starting point when circulating along the first circumferential direction, then the chamber is an annular chamber 50. Figure 1 , Figure 8 , Fig.14 and Fig.15 , Fig. 20 The chamber in the corresponding embodiment is also an annular chamber 50 .

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

[0121] See also Fig.16 as well as Fig.17 When the air conditioner is in the fresh air mode, the first valve group 160 is in a closed state, and the second valve group 170 is in an open state. The air in the second area 30 flows into the annular chamber 50 from the second opening 123 under the drive of the driving motor 190, and flows to the first opening 113 through the second valve group 170 in an open state, and flows into the first area 20 through the first opening 113. In this fresh air mode, since the first valve group 160 is in a 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 to the first opening 113 through the second valve group 170.

[0122] See also Fig.14 as well as Fig.15 When the air conditioner is in the dust removal mode, the first valve group 160 is in an open state, so that the portion of the annular chamber 50 between the first opening 113 and the second opening 123 is in communication, and the second valve group 170 is in a closed state, so that the portion of the annular chamber 50 between the second opening 123 and the third opening 124 is not in communication. The air in the first area 20 flows into the annular chamber 50 from the third opening 124 under the drive of the drive motor 190, flows to the second opening 123 through the first valve group 160 in an open state, and then flows into the second area 30 through the second opening 123.

[0123] In some embodiments, the first valve assembly 160 is configured such that when it is in an open state, the first opening 113 can be closed by the first valve assembly 160, see Fig.15 In other embodiments, the first opening 113 may also be closed by providing other structures. Fig.18 as well as Fig.15When the air conditioner is in exhaust mode, the second valve group 170 and the first opening 113 are both in a closed state, and the first valve group 160 and the third opening 124 are both in an open state. In some other embodiments, the housing assembly 100 further includes a third valve group 180, which is configured to open or close the third opening 124. Fig.16 as well as Fig.17 When the air conditioner is in the fresh air mode, the first valve group 160 and the third opening 124 are both in a closed state, and the second valve group 170 and the first opening 113 are both in an open state.

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

[0125] The third aspect of the present invention also provides an air conditioner, which includes the ventilation module described in the above embodiment, see Fig.19 . The air conditioner also includes a dust removal component 40. The ventilation function of the air conditioner can be switched between a fresh air mode, a dust removal mode, an exhaust mode and a 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 by the dust removal component 40 during the dust removal process to prevent 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 not need to add an additional dust removal channel dedicated to conducting dust, thereby saving the internal space of the air conditioner. And the power for driving the dust to be exported to the outside is provided by the drive motor 190 of the ventilation module, without the need to add an additional drive motor, thereby reducing the number of motors of the air conditioner and reducing the material cost of the air conditioner.
