As shown in fig. 2, the inlet of the ventilation chamber 101 (e.g., the second inlet 101b shown in fig. 2) is adapted to be in direct or indirect communication with the outside of the room, and when the inlet of the ventilation chamber 101 is in a communication state with the outside of the room, if the air pressure inside the ventilation chamber 101 is less than the air pressure of the outdoor environment, the outdoor air may enter the ventilation chamber 101 through the second inlet 101 b.

As shown in fig. 3, the outlet of the ventilation chamber 101 (e.g., the first outlet 101c shown in fig. 3) is adapted to be in direct or indirect communication with the discharge chamber 103, and when the discharge chamber 103 is in a communication state with the room and the discharge chamber 103 is in a communication state with the outlet of the ventilation chamber 101, if the air pressure in the ventilation chamber 101 is greater than the air pressure of the indoor environment, the ventilation chamber 101 can discharge air to the room through the discharge chamber 103.

As shown in fig. 4, the outlet of the ventilation chamber 101 (e.g. the second outlet 101d shown in fig. 3) is adapted to be directly or indirectly communicated with the fresh air chamber 102, and when the fresh air chamber 102 is in a communication state with the outside and the fresh air chamber 102 is in a communication state with the outlet of the ventilation chamber 101, if the air pressure in the ventilation chamber 101 is greater than the air pressure of the outdoor environment, the ventilation chamber 101 can exhaust air to the outside through the fresh air chamber 102.

Briefly, in one particular example of the invention, as shown in fig. 2-4, the ventilation chamber 101 may have two inlets, a first inlet 101a and a second inlet 101b, respectively, and the ventilation chamber 101 may also have two outlets, a first outlet 101c and a second outlet 101d, respectively. Wherein the first inlet 101a is adapted to communicate with the room, the second inlet 101b is adapted to communicate with the fresh air chamber 102, the first outlet 101c is adapted to communicate with the exhaust chamber 103, and the second outlet 101d is adapted to communicate with the fresh air chamber 102.

As shown in fig. 2 to 4, the fresh air processing component 100 may include an air processing assembly 4, the air processing assembly 4 is disposed in the exhaust chamber 103, and when the air flow enters the exhaust chamber 103 and passes through the air processing assembly 4, the air flow can be processed by the air processing assembly 4, so that the quality of the air discharged from the exhaust chamber 103 can be ensured.

As shown in fig. 1 and 2, the air conditioning device 1000 may include a control valve assembly, and the control valve assembly may be provided in the housing assembly 1 or may not be provided in the housing assembly 1. The control valve assembly may include a first valve assembly 31 and a second valve assembly 32, and the first valve assembly 31 and the second valve assembly 32 are independent of each other, that is, the first valve assembly 31 and the second valve assembly 32 are different valve groups and are independently controlled.

As shown in fig. 1 and 2, in the open state of the first valve assembly 31, the outlet of the ventilation chamber 101 is in communication with the indoor space through the ventilation chamber 103 and the outlet port 302. In particular, the first valve assembly 31 is switchable between an open state and a closed state. As shown in fig. 2 and 3, when the first valve assembly 31 assumes an open state, the ventilation chamber 101 can be exhausted from the outlet port 302 into the room through the exhaust chamber 103 when the pressure of the ventilation chamber 101 is greater than the indoor pressure. As shown in fig. 4, in the closed state of the first valve assembly 31, even if the pressure of the ventilation chamber 101 is higher than the indoor pressure, the ventilation chamber 101 cannot discharge air from the outlet port 302 to the indoor through the discharge chamber 103, for example, the ventilation chamber 101 cannot discharge air to the discharge chamber 103, or the ventilation chamber 101 cannot discharge air to the indoor through the outlet port 302 but the discharge chamber 103 cannot discharge air to the indoor through the discharge chamber 103, or the ventilation chamber 101 cannot discharge air to the discharge chamber 103 nor the discharge chamber 103 can discharge air to the indoor through the outlet port 302.

As shown in fig. 4, in the open state of the second valve assembly 32, the outlet of the ventilation chamber 101 is in communication with the fresh air chamber 102. Specifically, the second valve assembly 32 is switchable between an open state and a closed state. As shown in fig. 4, when the second valve assembly 32 assumes an open state, the ventilation chamber 101 may vent to the fresh air chamber 102 when the pressure of the ventilation chamber 101 is greater than the pressure of the fresh air chamber 102. As shown in fig. 1 and 2, when the second valve assembly 32 assumes a closed state, the ventilation chamber 101 cannot discharge air into the fresh air chamber 102 even if the pressure of the ventilation chamber 101 is greater than the pressure of the fresh air chamber 102.

Thus, the air treatment device 1000 according to the embodiment of the present invention may have at least the following three operation modes.

In a first mode of operation, as shown in fig. 2, when the first valve assembly 31 is in an open state and the second valve assembly 32 is in a closed state, and when the inlet of the ventilation chamber 101 is able to draw air from the outside and the outlet pressure of the ventilation chamber 101 is lower than the inlet pressure of the ventilation chamber 101, fresh outdoor air enters the ventilation chamber 101 and is then exhausted from the ventilation chamber 101 to the exhaust chamber 103, and after being processed by the air processing assembly 4, is exhausted to the inside through the outlet 302. Therefore, the fresh air function of introducing outdoor fresh air from the outdoor to the indoor can be realized.

In a second mode of operation, as shown in fig. 3, the first valve assembly 31 is in an open state and the second valve assembly 32 is in a closed state, when the inlet of the ventilation chamber 101 can draw air from the room and the outlet pressure of the ventilation chamber 101 is lower than the inlet pressure of the ventilation chamber 101, the room air enters the ventilation chamber 101, is then exhausted from the ventilation chamber 101 to the exhaust chamber 103, is processed by the air processing assembly 4, and is then exhausted into the room through the air outlet 302. Therefore, the internal circulation function of introducing air from the room for treatment and then discharging the air back to the room can be realized.

In a third mode of operation, as shown in fig. 4, the first valve assembly 31 is in a closed state, the second valve assembly 32 is in an open state, when the inlet of the ventilation chamber 101 can suck air from the indoor, the fresh air chamber 102 can exhaust air to the outdoor, and the outlet pressure of the ventilation chamber 101 is lower than the inlet pressure of the ventilation chamber 101, the indoor air enters the ventilation chamber 101 and then is exhausted from the ventilation chamber 101 to the fresh air chamber 102, and the fresh air chamber 102 exhausts the air to the outdoor. Therefore, the air exhaust function of introducing air from the indoor and then exhausting the air to the outdoor can be realized, and the effect of discharging the air to the outdoor can be achieved.

Under the fresh air function, the path of the airflow flowing through the shell assembly 1 is called a fresh air channel, under the internal circulation function, the path of the airflow flowing through the shell assembly 1 is called an internal circulation channel, and under the exhaust function, the path of the airflow flowing through the shell assembly 1 is called an exhaust channel. As described above, by disposing the air processing assembly 4 in the exhaust chamber 103, the air processing assembly 4 is disposed on the fresh air channel and the internal circulation channel, and the air can be processed first and then discharged into the room, so that the fresh air channel and the internal circulation channel can be defined as the air processing channel. And the air treatment assembly 4 may not be provided on the exhaust air channel, so that the service life of the air treatment assembly 4 may be prolonged. In addition, according to the air treatment apparatus 1000 of the embodiment of the present invention, the first valve assembly 31 and the second valve assembly 32 are provided, so that the exhaust duct can be closed while the air treatment duct is opened, and the air treatment duct can be closed while the exhaust duct is opened, thereby realizing different functions.

According to the air processing device 1000 of the embodiment of the invention, the inner cavity of the housing assembly 1 is designed as above, and the first valve assembly 31 and the second valve assembly 32 with the above functions are arranged, so that at least the switching of the internal circulation function, the fresh air function and the air exhaust function can be realized, and different requirements of users can be met. Moreover, the first valve assembly 31 and the second valve assembly 32 are independent from each other, so that the setting positions of the two sets of valve assemblies are not restricted or influenced with each other, and the setting position of each valve assembly can be selected respectively according to the actual structural layout requirements, so that the flexibility of design is improved, and the adaptability to different machine types is improved.

Of course, the present invention is not limited thereto, and in other examples of the present invention, the inlet of the ventilation chamber 101 may also be directly or indirectly communicated with the indoor space only, or the inlet of the ventilation chamber 101 may also be directly or indirectly communicated with the outdoor space only, which is not described in detail.

In some embodiments of the present invention, as shown in fig. 2, the fresh air component 100 may include a fan assembly 2, and the fan assembly 2 may be disposed in the ventilation chamber 101, that is, at least a portion of the fan assembly 2 is disposed in the ventilation chamber 101, and when the fan assembly 2 is in operation, an outlet pressure of the ventilation chamber 101 is less than an inlet pressure of the ventilation chamber 101. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the fan assembly 2 may not be disposed in the ventilation chamber 101, for example, the fan assembly 2 may also be disposed in the fresh air chamber 102 and the exhaust air chamber 103, and the like, and in addition, the specific type of the fan assembly 2 is not limited, and may be specifically selected according to the air flow direction, the air supply requirement, and the like, and is not limited herein, and may include, for example, a centrifugal fan, a cross flow fan, an axial flow fan, and the like.

In some embodiments of the invention, as shown in fig. 2, the inlet of the ventilation chamber 101 (second inlet 101b as shown in fig. 2) is adapted to communicate with the outside of the room through the fresh air chamber 102. Therefore, by utilizing the characteristic that the fresh air chamber 102 can be communicated with the outdoor, the inlet (such as the second inlet 101b shown in fig. 2) of the ventilation chamber 101 is communicated with the fresh air chamber 102, so that the indirect communication between the inlet of the ventilation chamber 101 and the outdoor can be effectively ensured, and the structure can be simplified. Of course, the present invention is not limited to this, and the inlet of the ventilation chamber 101 may also be set to communicate with the outside without passing through the fresh air chamber 102, that is, the inlet of the ventilation chamber 101 may communicate with the outside through a path other than the fresh air chamber 102, for example, a hose is provided, such that one end of the hose is directly communicated to the outside, and the other end of the hose is directly communicated to the ventilation chamber 101, and so on, which will not be described herein.

For example, in some specific examples of the present invention, as shown in fig. 2, the air conditioning device 1000 may have a fresh air port 303 thereon, and the fresh air port 303 may be adapted to communicate with the outside so that the air conditioning device 1000 is adapted to exhaust air to the outside or introduce fresh air from the outside through the fresh air port 303, and in this case, the fresh air chamber 102 may be adapted to communicate with the fresh air port 303 directly or indirectly, and the inlet (e.g., the second inlet 101b shown in fig. 2) and the outlet (e.g., the second outlet 101d shown in fig. 2) of the ventilation chamber 101 are respectively in indirect communication with the fresh air port 303 through the fresh air chamber 102.

When the fresh air port 303 and the outdoor space are in a communication state, and the fresh air port 303 and the fresh air chamber 102 are in a communication state. As shown in fig. 2, if the air pressure inside the ventilation chamber 101 is less than the air pressure of the outdoor environment, the outdoor air can enter the fresh air chamber 102 through the fresh air port 303 and then enter the ventilation chamber 101 through the fresh air chamber 102. As shown in fig. 4, if the air pressure in the ventilation chamber 101 is greater than the air pressure in the outdoor environment, when the second valve assembly 32 is opened, the air in the ventilation chamber 101 can be discharged to the fresh air chamber 102, and the air in the fresh air chamber 102 can be discharged to the outside through the fresh air opening 303.

In some embodiments of the present invention, as shown in fig. 2, the control valve assembly may further comprise a third valve assembly 33, the third valve assembly 33 being in an open state, the inlet of the ventilation chamber 101 (e.g., the second inlet 101b shown in fig. 2) being in communication with the fresh air chamber 102. Specifically, the third valve assembly 33 is switchable between an open state and a closed state. As shown in fig. 2, with the third valve assembly 33 in the open state, the ventilation chamber 101 can draw air from the fresh air chamber 102, i.e. if the air pressure in the ventilation chamber 101 is less than the air pressure in the fresh air chamber 102, the air in the fresh air chamber 102 will flow into the ventilation chamber 101 through the inlet (shown as the second inlet 101b in fig. 2) of the ventilation chamber 101.

As shown in fig. 3, when the third valve assembly 33 is in the closed state, the inlet of the ventilation chamber 101 (e.g., the second inlet 101b shown in fig. 3) cannot suck air from the fresh air chamber 102, i.e., if the air pressure in the ventilation chamber 101 is lower than the air pressure in the fresh air chamber 102, the air in the fresh air chamber 102 cannot flow into the ventilation chamber 101. At this time, if the ventilation chamber 101 is in a communication state with the indoor, indoor air may flow into the ventilation chamber 101 through an inlet (a first inlet 101a as shown in fig. 3) of the ventilation chamber 101.

From this, through switching third valve module 33 to the open mode, can guarantee under the new trend function, by outdoor to ventilation cavity 101 provide the new trend, through switching third valve module 33 to the closed condition, can guarantee including under circulation function and the function of airing exhaust, only by indoor to ventilation cavity 101 provide the air, and can not have outdoor new trend to get into ventilation cavity 101 to improve the work efficiency of inner circulation function and the function of airing exhaust, reduce the energy consumption.

In some embodiments of the present invention, as shown in fig. 4 to 5, the fresh air chamber 102 is located at the rear side of the ventilation chamber 101, the third valve assembly 33 is disposed between the front portion of the fresh air chamber 102 and the rear portion of the ventilation chamber 101, that is, when the ventilation chamber 101 has the second inlet 101b, and the second inlet 101b communicates with the outlet of the fresh air chamber 102, the third valve assembly 33 may be disposed at the second inlet 101b, the third valve assembly 33 may include a plurality of first vertical baffles 333, the plurality of first vertical baffles 333 are arranged in sequence in the left-right direction, each first vertical baffle 333 is pivotally connected to the housing assembly 1, for example, the pivot axis of each first vertical baffle 333 extends vertically. Therefore, the third valve assembly 33 has a simple structure, is convenient to control, occupies a small space, and has a good switch switching effect.

For example, in the closed state of the third valve assembly 33, the plurality of first vertical baffles 333 are substantially located on the same plane, two adjacent first vertical baffles 333 are connected, overlapped, or have only a small air flow gap, and in the open state of the third valve assembly 33, the plurality of first vertical baffles 333 are parallel to each other, so that a larger distance between two adjacent first vertical baffles 333 can be ensured, the air flow passing rate is improved, the wind resistance is reduced, and the energy consumption is reduced.

In addition, referring to fig. 5, the third valve assembly 33 may further include a third actuator and a third connecting rod 332, the third connecting rod 332 extends in the left-right direction, the upper end or the lower end of the first vertical baffles 333 is connected to the third connecting rod 332, the third actuator drives one of the first vertical baffles 333 to rotate, and the first vertical baffles 333 drives the remaining third vertical baffles to rotate through the third connecting rod 332. Therefore, the structure of the third valve assembly 33 is simple, and it is convenient to control the third valve assembly 33 to switch between the open state and the closed state.

In some embodiments of the present invention, as shown in fig. 4 and 5, the first valve assembly 31 may include a downstream control valve 3101, the downstream control valve 3101 being disposed downstream of the air handling assembly 4. That is, the downstream control valve 3101 is located downstream of the air handling component 4 in the airflow direction. Thus, when the downstream control valve 3101 is closed, even if the air flow discharged from the ventilation chamber 101 enters the exhaust chamber 103 and is processed by the air processing assembly 4, the air flow is intercepted by the downstream control valve 3101 and cannot flow to the air outlet 302, so that the air flow in the ventilation chamber 101 can be prevented from being discharged from the air outlet 302 to the room through the exhaust chamber 103.

Therefore, by locating the downstream control valve 3101 downstream of the air handling assembly 4, the downstream control valve 3101 may be located with a greater amount of space while ensuring that the downstream control valve 3101 meets the functional requirements described above, thereby allowing the selection of multiple versions or a greater number of downstream control valves 3101, better performing the function of the first valve assembly 31, and facilitating early installation and later maintenance of the downstream control valve 3101.

In some embodiments of the present invention, as shown in fig. 4 and 5, a downstream control valve 3101 is provided at the outlet vent 302 for controlling the opening and closing of the outlet vent 302. Thereby, the installation of the downstream control valve 3101 is more facilitated. For example, in a specific example of the present invention, the air conditioning device 1000 may further include a cabinet member 300, the housing assembly 1 is located inside the cabinet member 300, the outlet port 302 is formed on the cabinet member 300, and the downstream control valve 3101 is mounted on the cabinet member 300 and is used to control the opening and closing of the outlet port 302, thereby facilitating the installation. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the housing assembly 1 may also be directly used as an external appearance surface of the air conditioning apparatus 1000, in this case, the housing assembly 1 is not disposed in the casing member 300, and in this case, the air outlet 302 may be formed on the housing assembly 1.

In addition, in other embodiments of the present invention, the downstream control valve 3101 may not be disposed at the air outlet 302, for example, in other embodiments, the downstream control valve 3101 may also be disposed upstream of the air outlet 302, that is, in the airflow flowing direction, the downstream control valve 3101 is located between the air treatment assembly 4 and the air outlet 302, when the downstream control valve 3101 is in the closed state, the airflow discharged from the ventilation chamber 101 will be intercepted by the downstream control valve 3101 even though the airflow enters the exhaust chamber 103 and is treated by the air treatment assembly 4, and thus will not flow to the air outlet 302, so that the airflow in the ventilation chamber 101 can be prevented from being discharged from the air outlet 302 to the room through the exhaust chamber 103.

For example, when the housing assembly 1 is located in the cabinet member 300, the outlet 302 is formed on the cabinet member 300, the housing assembly 1 may be formed with the indoor outlet 106 communicating with the outlet 302, and the downstream control valve 3101 may be disposed at the indoor outlet 106 so as to be located between the air handling assembly 4 and the outlet 302. In addition, when the downstream control valve 3101 is located between the air treatment assembly 4 and the air outlet 302, the first valve assembly 31 may also include a valve disposed at the air outlet 302, or the air outlet 302 may not be provided with a valve, and may be in an open state, or a ventilation grille or the like.

In some embodiments of the invention, as shown in fig. 4 and 5, the downstream control valve 3101 may include a plurality of second vertical baffles 313 arranged in series in a transverse direction of the outlet vent 302, for example, with a pivot axis of each second vertical baffle 313 extending in a vertical direction. Therefore, the downstream control valve 3101 has a simple structure, is convenient to control, occupies a small space, and has a good switching effect.

For example, when the downstream control valve 3101 is in the closed state, the second vertical baffles 313 are substantially located on the same plane, two adjacent second vertical baffles 313 are connected, overlapped or have only a small airflow gap, and when the downstream control valve 3101 is in the open state, the second vertical baffles 313 are parallel to each other, so that the distance between two adjacent second vertical baffles 313 can be ensured to be large, the airflow passing rate can be improved, the wind resistance can be reduced, and the energy consumption can be reduced.

In addition, referring to fig. 5, the downstream control valve 3101 may further include a first driver 311 and a first link, the first link extends along the lateral direction of the air outlet 302, the upper end or the lower end of the second vertical baffles 313 is connected to the first link, the first driver 311 drives one of the second vertical baffles 313 to rotate, and the second vertical baffle 313 drives the remaining second vertical baffles 313 to rotate through the first link. Therefore, the downstream control valve 3101 is simple in structure, facilitating control of the downstream control valve 3101 to switch between the open state and the closed state.

In some embodiments of the present invention, as shown in FIG. 6, the first valve assembly 31 may further include an upstream control valve 3102, the upstream control valve 3102 being disposed upstream of the air treatment assembly 4. That is, the upstream control valve 3102 may be located upstream of the air treatment assembly 4 in the airflow direction. Thus, when the upstream control valve 3102 is closed, the air flow discharged from the ventilation chamber 101, even though entering the discharge chamber 103, will not be treated by the air treatment module 4, thereby reducing the utilization rate of the air treatment module 4 and prolonging the service life of the air treatment module 4.

In addition, it should be noted that, in some other embodiments of the present invention, the first valve assembly 31 may also include an upstream control valve 3102 disposed upstream of the air treatment assembly 4 and a downstream control valve 3101 disposed at the air outlet 302, so that on one hand, the upstream control valve 3102 may be used to reduce the utilization rate of the air treatment assembly 4, and on the other hand, the downstream control valve 3101 may be used to improve the tightness of the air outlet 302.

In some embodiments of the present invention, as shown in fig. 6, the upstream control valve 3102 may be disposed below the air treatment assembly 4, the upstream control valve 3102 may include a plurality of first transverse baffles 312, each of the first transverse baffles 312 may be pivotally connected to the housing assembly 1, and the plurality of first transverse baffles 312 may be arranged in a front-to-rear direction, for example, the pivot axis of each of the first transverse baffles 312 may extend in a left-to-right direction. Therefore, the upstream control valve 3102 has a simple structure, is convenient to control, occupies a small space, and has a good switching effect.

For example, when the upstream control valve 3102 is in the closed state, the plurality of first transverse baffles 312 are substantially located on the same plane, two adjacent first transverse baffles 312 are connected, overlapped or have only a small airflow gap, and when the upstream control valve 3102 is in the open state, the plurality of upstream control valves 3102 are parallel to each other, so that the distance between two adjacent upstream control valves 3102 can be ensured to be large, the airflow passing rate can be improved, the wind resistance can be reduced, and the energy consumption can be reduced.

In addition, the upstream control valve 3102 may further include a sixth actuator and a sixth link, the sixth link extends in the front-rear direction, the left end or the right end of the first transverse barrier 312 is connected to the sixth link, the sixth actuator drives one of the first transverse barrier 312 to rotate, and the first transverse barrier 312 drives the remaining first transverse barrier 312 to rotate through the sixth link. Therefore, the upstream control valve 3102 is simple in structure, facilitating control of the upstream control valve 3102 to switch between the open state and the closed state.

Thereby, the intake path and the exhaust path from between the ventilation chamber 101 and the fresh air chamber 102 can be better shortened, and the exhaust path from the ventilation chamber 101 to the exhaust chamber 103 can be shortened, so that the energy consumption is reduced, and the structure of the housing assembly 1 can be made small and compact.

As shown in fig. 4 and 5, when the second valve assembly 32 is disposed at the second outlet 101d and the third valve assembly 33 is disposed at the second inlet 101b between the front of the fresh air chamber 102 and the rear of the ventilation chamber 101, the second valve assembly 32 can be located above the third valve assembly 33, so as to ensure that the third valve assembly 33 and the second valve assembly 32 are installed in a large space and avoid interference between the two.

In some embodiments of the present invention, as shown in fig. 4 and 5, second valve assembly 32 includes a second cross bar 322, second cross bar 322 being pivotally coupled to housing assembly 1, e.g., an upper end of second cross bar 322 being pivotally coupled to housing assembly 1, e.g., a pivot axis of second cross bar 322 extending in a side-to-side direction. Therefore, the second valve assembly 32 has a simple structure, is convenient to control, occupies a small space and has a good switch switching effect. In addition, referring to fig. 7, the second valve assembly 32 may further include a second driver 321, and the second driver 321 is directly connected to the second cross bar 322 to drive the second cross bar 322 to rotate, so that the second valve assembly 32 has a simple structure and is convenient to control to switch between the open state and the closed state.

In some embodiments of the invention, as shown in fig. 4 and 5, a centrifugal wind wheel 21 is provided in the ventilation chamber 101. From this, the arrangement of ventilation cavity 101, new trend cavity 102 and air exhaust cavity 103 accords with centrifugal wind wheel 21's operating characteristics for centrifugal wind wheel 21 can follow the rear side air inlet, from the upside air-out, thereby through utilizing centrifugal wind wheel 21, can improve the air volume, satisfies requirements such as big fresh air volume. It should be noted that the terms of orientation, such as up, down, left, right, front, and back, are used herein for simplicity and clarity of description, and are not to be construed as limiting the present application, for example, when the air processing apparatus 1000 is used in a floor air conditioner, the side of the floor air conditioner facing the user is front, the side facing away from the user is back, the up-down direction of the floor air conditioner is vertical, and the direction perpendicular to the vertical direction is horizontal.

For example, in the specific example shown in fig. 4 and 5, the ventilation chamber 101 may include a front chamber 1011, a rear chamber 1012, and an upper chamber 1013, the rear chamber 1012 being located in front of the fresh air chamber 102, the front chamber 1011 being located in front of the rear chamber 1012, the centrifugal wind wheel 21 being provided at the front chamber 1011, the upper chamber 1013 being located above the front chamber 1011 and the rear chamber 1012, the upper chamber 1013 being in communication with the top of the front chamber 1011, the top of the upper chamber 1013 being configured as the first outlet 101c, and the rear of the upper chamber 1013 being configured as the second outlet 101 d.

In addition, the fresh air component 100 may further include a driving motor 22 connected to the centrifugal wind wheel 21, so as to obtain the fan assembly 2 composed of the centrifugal wind wheel 21 and the driving motor 22, and the driving motor 22 is installed on the housing assembly 1, so that the centrifugal wind wheel 21 is located in the front chamber 1011, so that the front chamber 1011 can be used as a volute of the fan assembly 2.

In some embodiments of the present invention, as shown in fig. 1 and 3, the air conditioning device 1000 further has a return air opening 301 thereon, the return air opening 301 is adapted to communicate with the room, so that the air conditioning device 1000 is adapted to introduce air in the room through the return air opening 301, and the control valve assembly further includes a fourth valve assembly 34, and in an open state of the fourth valve assembly 34, an inlet (e.g., the first inlet 101a shown in fig. 3) of the ventilation chamber 101 is in communication with the room through the return air opening 301. At this time, if the air pressure inside the ventilation chamber 101 is less than the air pressure of the indoor environment, indoor air may enter the ventilation chamber 101 through the return air opening 301.

Specifically, the fourth valve assembly 34 is switchable between an open state and a closed state. As shown in fig. 3 and 4, when the fourth valve assembly 34 is in the open state, the ventilation chamber 101 is in the communication state with the air return opening 301, the air return opening 301 is in the communication state with the room, and the ventilation chamber 101 can suck air from the room through the air return opening 301, that is, if the air pressure in the ventilation chamber 101 is lower than the air pressure of the indoor environment, the air in the room can flow into the ventilation chamber 101 through the air return opening 301.

As shown in fig. 2, when the fourth valve assembly 34 is in the closed state, the ventilation chamber 101 and the air return opening 301 are in the blocked state, and/or the air return opening 301 and the room are in the blocked state, the ventilation chamber 101 cannot suck air from the room through the air return opening 301, that is, if the air pressure in the ventilation chamber 101 is less than the air pressure of the indoor environment, the air in the room cannot flow into the air return opening 301, or the air in the room cannot flow into the ventilation chamber 101, or the air in the room cannot flow into the air return opening 301, and the air flowing into the air return opening 301 cannot flow into the ventilation chamber 101.

Thus, as shown in fig. 2, the fourth valve assembly 34 can be switched to the closed state under the fresh air function, and only the outdoor air supplies air to the ventilation chamber 101, so as to ensure that the fresh air enters in a sufficient amount, as shown in fig. 3 and 4, the fourth valve assembly 34 is switched to the open state under the internal circulation function and the exhaust function, so that the requirement of supplying air from the indoor air to the ventilation chamber 101 can be met.

The positions of the air return opening 301 and the fourth valve assembly 34 are not limited as long as the above requirements are satisfied. For example, as described above, when the air conditioning device 1000 includes the cabinet member 300 and the casing assembly 1 is located in the cabinet member 300, the air return opening 301 may be formed on the cabinet member 300, and at this time, the casing assembly 1 may be formed with the indoor air return opening 105 communicating with the air return opening 301, and in a specific example, the first inlet 101a and the indoor air return opening 105 may be the same opening, so that the air intake path from the air return opening 301 to the ventilation chamber 101 may be further shortened, and the structure of the casing assembly 1 may be made small and compact. And the return air opening 301 may be formed at the case assembly 1 when the case assembly 1 serves as an external appearance surface of the air conditioning device 1000.

For example, in some embodiments, the fourth valve assembly 34 may be provided at the return air opening 301 for controlling opening and closing of the return air opening 301, thereby having a large installation space and facilitating control. Further, the fourth valve assembly 34 may be in the form of an electrically operated switch door, an electrically operated air deflector, a manually operated switch door, or the like. Of course, the present invention is not limited thereto, and the fourth valve assembly 34 may also be disposed on the airflow channel between the air return opening 301 and the inlet of the ventilation chamber 101, for example, when the housing assembly 1 is located in the housing part 300 and the air return opening 301 is formed on the housing part 300, the housing assembly 1 has the indoor air return opening 105 thereon, the indoor air return opening 105 is the inlet of the ventilation chamber 101 and is communicated with the air return opening 301 on the housing part 300, at this time, the fourth valve assembly 34 may be disposed at the indoor air return opening 105 on the housing assembly 1, and so on, which will not be described herein.

Of course, the present invention is not limited to this, in other embodiments of the present invention, the control valve assembly may not have the fourth valve assembly 34, and in this case, the ventilation chamber 101 may be in a normally connected state with the air return opening 301, and the air return opening 301 is also in a normally connected state with the room, as long as the air pressure in the ventilation chamber 101 is smaller than the air pressure of the indoor environment, the indoor air will flow into the ventilation chamber 101 through the air return opening 301, for example, under the above-mentioned fresh air function, internal circulation function and exhaust function, the indoor air may enter the ventilation chamber 101. For example, under the new trend function, indoor air and outdoor new trend get into ventilation cavity 101 simultaneously, then are handled the back by air treatment component 4 and are arranged to indoor to can have certain inner loop effect concurrently under the function that realizes the new trend. In addition, when the control valve assembly does not have the fourth valve assembly 34, a ventilation grille can be arranged at the air return opening 301, so that a safety effect is achieved.

In some embodiments of the present invention, as shown in fig. 2, the fresh air component 100 may further include: fresh air pipe 5, the control valve subassembly can also include: and a fifth valve assembly 35, one end of the fresh air pipe 5 defines a fresh air port 303, and the other end of the fresh air pipe 5 is communicated with the fresh air chamber 102. The fifth valve assembly 35 is disposed in the fresh air duct 5, and when the fifth valve assembly 35 is in an open state, the fresh air chamber 102 is in a communication state with the outside through the fresh air duct 5. Therefore, by providing the fifth valve assembly 35, the air-tightness of the entire air processing apparatus 1000 can be improved without using the fresh air duct 5 for intake or exhaust.

Specifically, the fifth valve assembly 35 is switchable between an open state and a closed state. As shown in fig. 2, when the fifth valve assembly 35 is in the open state, the fresh air chamber 102 can introduce the outdoor air from the outside through the fresh air pipe 5, that is, if the air pressure of the fresh air chamber 102 is lower than the outdoor air pressure, the outdoor air flows into the fresh air pipe 5 and then enters the fresh air chamber 102. As shown in fig. 3, when the fifth valve assembly 35 is in the closed state, the fresh air chamber 102 cannot introduce outdoor air from the outside through the fresh air duct 5, that is, at this time, if the air pressure of the fresh air chamber 102 is lower than the outdoor air pressure, the outdoor air cannot flow into the fresh air duct 5, or the outdoor air may flow into the fresh air duct 5, but the air in the fresh air duct 5 cannot enter the fresh air chamber 102, or the outdoor air cannot flow into the fresh air duct 5, and the air in the fresh air duct 5 cannot enter the fresh air chamber 102. As shown in fig. 4, when the fifth valve assembly 35 is in the open state, if the air pressure in the fresh air chamber 102 is greater than the outdoor air pressure, the air in the fresh air chamber 102 is discharged to the outside through the fresh air pipe 5.

It should be noted that the fresh air duct 5 can be connected to the outside through a fresh air hose, so that convenience and reliability of communication between the fresh air duct 5 and the outside can be improved. In addition, it should be noted that the number of the fresh air ducts 5 is not limited, and may be one or more, and when a plurality of fresh air ducts are provided, a plurality of fresh air ducts 5 may be used simultaneously, or only one of the fresh air ducts may be used, and the others may be left for standby. It should be noted that the specific structure of the fifth valve assembly 35 is not limited, for example, the fifth valve assembly 35 may include a fifth driver and a fifth flap, and the fifth driver drives the fifth flap to rotate, so that the structure of the fifth valve assembly 35 is simple and the fifth valve assembly 35 is easy to control to switch between the open state and the closed state.

In addition, when the air conditioning device 1000 further includes the cabinet member 300, and the casing assembly 1 is located in the cabinet member 300, both the return air opening 301 and the air outlet opening 302 may be formed on the cabinet member 300, as shown in fig. 2 to 4, the fresh air opening 303 is formed on the fresh air duct 5, the casing assembly 1 may be formed with the outdoor fresh air opening 104, the indoor return air opening 105, and the indoor air outlet opening 106, the outdoor fresh air opening 104 being communicated with the fresh air chamber 102, the indoor return air opening 105 being communicated with the ventilation chamber 101, the indoor air outlet opening 106 being communicated with the exhaust chamber 103, the outdoor fresh air opening 104 being communicated with the fresh air opening 303 through the fresh air duct 5, the indoor return air opening 105 being communicated with the return air opening 301, and the indoor air outlet opening 106 being communicated with the air outlet opening 302. When the housing assembly 1 is not disposed in the casing member 300, the housing assembly 1 may serve as an external appearance surface of the air conditioner 1000, and in this case, the air return opening 301 and the air outlet opening 302 may be formed on the housing assembly 1.

Therefore, the indoor air outlet and the indoor air return are far away from each other, the air return problem is avoided, the air outlet area can be enlarged as much as possible, the air outlet requirement is guaranteed, the air inlet area is enlarged as much as possible, and the air inlet requirement is guaranteed. Of course, the present invention is not limited thereto, and the number and the arrangement positions of the outdoor fresh air inlet 104, the indoor return air inlet 105 and the indoor air outlet 106 may also be specifically adjusted according to the actual situation, as long as the ventilation requirements of the above functions are met, which is not described herein again.
