It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

As shown in fig. 1 to 3, in an embodiment, an air conditioning and ventilating assembly 10 is provided, which includes a driving member 11 and a ventilating assembly body 12, wherein an air duct 121 is disposed in the ventilating assembly body 12, and when the air conditioning and ventilating assembly 10 switches between heating and cooling modes, an air guiding direction of the air duct 121 is changed, so that air inlets 1211 at two ends of the air duct 121 are switched between an air inlet state and an air outlet state, thereby ensuring comfort of both the cooling and heating modes.

As shown in fig. 1 to fig. 3, the air inlet 1211 of the air duct 121 is provided with a filtering member 13, the filtering member 13 is movably connected to the side wall of the air duct 121, and the driving member 11 is connected to the filtering member 13 for driving the filtering member 13 to switch between the first position and the second position. In the first position, as illustrated by the filter element 13 located at the tuyere 1211 of the side 122 in fig. 3, the filter element 13 blocks the corresponding tuyere 1211; in the second position, as illustrated by the filter element 13 located at the tuyere 1211 of the bottom surface 123 in fig. 3, the filter element 13 hides from view the corresponding tuyere 1211. When the air inlet 1211 is switched to an air inlet state, the filtering member 13 is located at the first position, and when the air inlet 1211 is switched to an air outlet state, the filtering member 13 is located at the second position. Specifically, the change of the wind guiding direction in the wind tunnel 121 is mainly realized by controlling the rotation direction of the fan in the wind tunnel 121.

Further, alternatively, the filter member 13 and the driving member 11 may be provided at one of the air ports 1211 of the air path 121, or the filter member 13 and the driving member 11 may be provided at both of the air ports 1211 of the air path 121. For example, when one of the air ports 1211 of the air duct 121 is located indoors and the other air port 1211 is located outdoors, the filtering member 13 and the driving member 11 are only disposed at the air port 1211 located indoors, so that dust can be prevented from being blown into the room when the air from the indoor air port 1211 is exhausted. If the air conditioning and ventilating assembly 10 is a duct type air conditioner as shown in fig. 1 to fig. 3, two air ports 1211 of the air duct 121 are located indoors, wherein one air port 1211 is used as an air inlet, and the other air port 1211 is used as an air outlet. The air inlet and outlet states of the two air ports 1211 change with the change of the air guiding direction, and when the air guiding direction is switched, the two air ports 1211 are likely to blow dust, so that the filter member 13 and the driving member 11 may be disposed at both air ports 1211.

Furthermore, even if the state of the tuyere 1211 is switched to ensure the comfort of the cooling and heating modes, the positional relationship between the filter member 13 and the corresponding tuyere 1211 changes, so that when the tuyere 1211 is switched to the air-out state, the filter member 13 can be switched to the second position, and the filter member 13 is hidden from the tuyere 1211, thereby preventing the dust on the filter member 13 from being blown into the room. And when the wind gap 1211 is switched into the air inlet state by the air outlet state, driving piece 11 can drive filter piece 13 again and move to the primary importance, shelters from wind gap 1211, avoids in the dust inhales air conditioning system, ensures air conditioning system's cleanness, increase of service life has also avoided the dust to blow up the condition emergence that causes the threat to user's health simultaneously.

Specifically, the filter member 13 may be a filter net or other device capable of filtering dust, and is not particularly limited herein. The driving member 11 may be an electric motor, a hydraulic cylinder, or the like, and may be applied thereto as long as it can supply power. It should be noted that the driving member 11 can drive the filtering member 13 to move by directly connecting with the filtering member 13, and can also transmit the movement by an intermediate transmission structure, so as to realize the switching between the first position and the second position of the filtering member 13. Moreover, when the filtering piece 13 is driven by a motor, the filtering piece 13 can be driven by the original motor in the air conditioning system to move, so that the structure is simplified, and the cost is reduced.

And when driving piece 11 is the power spare that has the telescopic link for pneumatic cylinder etc. the telescopic link can with filter piece 13 and be connected, and filter piece 13 and slide the setting at wind gap 1211, the telescopic link is followed filter piece 13's slip direction and is arranged to drive through the flexible process of telescopic link filter piece 13 slides, realizes the switching of first position and second position.

If the driving member 11 is a motor, the motor can switch the filter member 13 between the first position and the second position by rotating forward and backward. Specifically, the manner in which the motor drives the filtering member 13 to switch between the first position and the second position may be realized by driving the filtering member 13 to turn over at the air port 1211. For example, in one embodiment, the filter element 13 is rotatably coupled to the ventilation assembly body 12, the motor is coupled to the filter element 13 for driving the filter element 13 to rotate relative to the ventilation assembly body 12, the motor is capable of driving the filter element 13 to rotate in a first direction to the first position, and the motor is capable of driving the filter element 13 to rotate in a second direction to the second position, the first direction being opposite to the second direction. Specifically, the filter member 13 may be a one-piece filter screen, and the first position and the second position are switched by rotating at the tuyere 1211 relative to the ventilation assembly body 12. Optionally, the filtering component 13 may be a louver structure composed of a plurality of blades, each blade is rotatably connected to the ventilation assembly body, and the driving component 13 drives each blade to rotate through a rotation process, so as to switch between the first position and the second position.

Alternatively, the motor can also move the filter element 13, so that the switching between the first position and the second position is effected. For example, in one embodiment, as shown in fig. 3 and 4, a transmission member 14 is disposed between the motor and the filter member 13, and both ends of the transmission member 14 are respectively connected to both ends of the filter member 13 to form a transmission loop. The filtering piece 13 is arranged in the air opening 1211 in a sliding mode, the main shaft of the motor is connected with the transmission piece 14 in a matching mode, the transmission piece 14 drives the filtering piece 13 to slide, and switching between the first position and the second position is achieved. When the operation mode of the air conditioning system is changed, the motor operates to drive the transmission member 14 to move, so as to drive the filter member 13 to slide, and thus, the switching between the first position and the second position is realized.

Specifically, the transmission member 14 may be a transmission rope or a transmission chain, and the manner in which the filter elements 13 are hidden by the transmission member 14 is also diversified.

For example, in one embodiment, as shown in fig. 3 and 4, the transmission member 14 includes a transmission rope or a transmission chain, the filter member 13 is a filter screen, two ends of the transmission rope or the transmission chain are respectively connected to two ends of the filter screen to form the transmission loop, two abutting rods 15 are arranged in the ventilation assembly body 12, the two abutting rods 15 are respectively located at two sides of the air opening 1211, and the transmission rope or the transmission chain connected to the filter screen is matched and connected to the main shaft of the motor after bypassing the abutting rods 15. As shown in fig. 4, the transmission rope or the transmission chain is wound at least one turn around at least one abutting rod 15, so that when the filter screen is located at the second position under the driving of the transmission rope or the transmission chain, as shown in fig. 5, the filter screen is wound around the abutting rod 15, so that the filter element 13 is hidden at the air opening 1211, and the dust on the filter element 13 is prevented from being blown into the room during air outlet, which poses a threat to the health of the user.

Further, in one embodiment, as shown in fig. 4, there are two conveying ropes or two transmission chains, the two conveying ropes or two transmission chains are disposed at intervals, and the positions where the two conveying ropes or two transmission chains are connected to the same end of the filter screen are distributed at intervals. Therefore, when the motor drives the two conveying ropes or the transmission chain to move, the filter screen can be driven to move more stably, and the stability and the reliability of operation are improved.

Moreover, the filter screen is driven to move by the conveying rope or the transmission chain, so that the condition that the air duct 121 is shielded by the transmission part is effectively avoided. When the filtering member 13 is hidden, the filtering member 13 is wound on the abutting rod 15 and is located outside the air duct 121, so that the ventilation volume of the air duct 121 is not affected, and the ventilation effect is improved.

Further, the width of the filter element 13 that is greater than the width of the air duct 121 may be set, and the two transmission ropes or the transmission chains are respectively connected to the 4 corners of the filter element 13, so that the transmission element 14 can be located outside the air duct 121, thereby avoiding shielding the air duct 121.

In another embodiment, the transmission member 14 includes a transmission rope or a transmission chain, the filtering member 13 is a filter screen, two ends of the transmission rope or the transmission chain are respectively connected to two ends of the filter screen to form the transmission loop, two abutting rods 15 are disposed in the ventilation assembly body 12, the two abutting rods 15 are respectively located at two sides of the air port 1211, the transmission rope or the transmission chain connected to the filter screen bypasses the abutting rods 15 and then is connected to the spindle of the motor in a matching manner, and a distance between at least one abutting rod 15 and the air port 1211 is not less than a length of the filter screen in a sliding direction, so that the filter screen can be hidden between the abutting rods 15 and the air port 1211 under the driving of the transmission rope or the transmission chain when the motor is driven. Of course, such an arrangement requires a sufficient space for disposing the abutting rod 15, and ensures the distance between the abutting rod 15 and the tuyere 1211.

In another embodiment, similar to the previous embodiment, the transmission member 14 includes a transmission rope or a transmission chain, the filter member 13 is a filter screen, two ends of the transmission rope or the transmission chain are respectively connected to two ends of the filter screen to form the transmission loop, two abutting rods 15 are arranged in the ventilation assembly body 12, the two abutting rods 15 are respectively located at two sides of the air opening 1211, and the transmission rope or the transmission chain connected to the filter screen is matched and connected to the main shaft of the motor after bypassing the abutting rods 15. The ventilation assembly body 12 is further provided with a limiting rod, the limiting rod and one of the abutting rods 15 are distributed along the inner wall of the ventilation assembly body 12, a conveying rope or a transmission chain which bypasses the abutting rod 15 bypasses the limiting rod and then is connected with the motor spindle in a matching mode, and the distance between the limiting rod and the abutting rod 15 is not smaller than the length of the filter screen in the sliding direction. So that the filter screen can be accommodated and hidden between the butting rod 15 and the limiting rod.

Further, as shown in fig. 3 and 5, the abutting rod 15 and/or the limiting rod in the above embodiments may be disposed in a direction perpendicular to the sliding direction of the filter member 13, so as to improve the stability of the hidden accommodation of the filter member 13.

Further, when the filter element 13 is driven by the motor to move in the air conditioning ventilation assembly 10, the rotating volute tongue 16 of the tuyere 1211 can also be arranged on the motor, so that the motor drives the filter element 13 and the rotating volute tongue 16 to move simultaneously, and synchronous movement between the two is realized. On the one hand, the structure is simplified, and on the other hand, the consistency of synchronous movement of the filter element 13 and the rotating volute tongue 16 is improved.

Specifically, as shown in fig. 3, the air inlet 1211 is provided with a rotating volute tongue 16, one end of the rotating volute tongue 16 is connected to the motor, and when the motor drives the filter element 13 to switch from the second position to the first position, the rotating volute tongue 16 is driven by the motor to rotate inwards, so that an auxiliary air inlet 161 is formed in the air inlet 1211, and the air inlet amount is increased; when the motor drives the filter element 13 to switch from the first position to the second position, the rotating volute tongue 16 is driven by the motor to rotate outwards, so that the other end of the rotating volute tongue 16 is lapped on the side wall of the air port 1211 to form an air outlet duct 162, and the air outlet effect is improved.

It should be noted that, based on the rotation direction of the rotating volute tongue 16 needing to be determined according to the state of the air inlet 1211, the rotating volute tongue 16 needs to rotate to the state that the other end is lapped on the side wall of the air inlet 1211 when the air inlet 1211 is in the air outlet state, so as to form the air outlet duct 162, and improve the air outlet effect; when the air inlet 1211 is in the air inlet state, the rotating spiral tongue 16 needs to rotate to be located in the air duct 121 to form the auxiliary air inlet 161, so as to increase the air inlet amount, and therefore, when the motor is arranged, the rotation direction of the motor needs to be considered, so that the movement direction of the filter element 13 when switching between the first position and the second position matches with the rotating spiral tongue 16.

For example, when the air inlet 1211 is switched to the air inlet state, the filter element 13 needs to be switched to the first position, the rotating volute tongue 16 needs to rotate into the air duct 121, and the rotation direction of the motor needs to meet the requirements of the two directions, namely the requirement of the movement direction of the filter element 13 and the requirement of the rotation direction of the rotating volute tongue 16 need to be consistent for the motor. As shown in fig. 3 and 5, the filter element 13 at the tuyere 1211 on the bottom surface 123 is in the second position, the rotating volute tongue 16 is overlapped with the tuyere 1211 to form the air outlet duct 162, at this time, the motor rotates clockwise, the rotating volute tongue 16 rotates inward, and the wound filter element 13 moves leftward and is unfolded under the driving of the transmission member 14 to shield the tuyere 1211.

Further, in order to improve the stability of the filter member 13 during the sliding process, in one embodiment, two guiding members are further disposed at the tuyere 1211, the guiding members are provided with guiding sliding grooves, the two guiding members are respectively disposed at two sides of the tuyere, the guiding sliding grooves are disposed along the sliding direction of the filter member 13, and when the filter member 13 is in the first position, two sides of the filter member 13 are respectively disposed in the guiding sliding grooves. When the driving member 11 drives the filtering member 13 to switch from the first position to the second position, the filtering member 13 slides in the guiding chute and moves under the guiding action of the guiding member.

When a transmission member 14 is further provided, the transmission member 14 can be connected to the part of the filter member 13 located in the guide chute, so that during the switching of the filter member 13 from the first position to the second position, the transmission member 14 slides into the guide chute, so that the transmission circuit formed by the transmission member 14 and the filter member 13 is always partially located in the slide chute, ensuring that the filter member 13 is reliably located in the tuyere 1211 when switched to the first position, and shielding the tuyere 1211.

Of course, when the air conditioning ventilation assembly 10 is further provided with two abutting rods 15, the two abutting rods 15 may also be disposed at positions flush with the air outlet, and the filtering member 13 may also be reliably located at the air outlet 1211 under the limiting effect of the abutting rods 15, so as to shield the air outlet 1211.

In one embodiment, as shown in fig. 3, the filter element 13 or the transmission element 14 may also be limited by a housing forming a side wall of the air duct 121, so that the filter element 13 can reliably block the air opening 1211 when the filter element 13 is located at the first position.

Further, in one embodiment, the ventilation assembly body 12 is further provided with a cleaning brush, and the cleaning brush and the filter member 13 are located on the same side of the tuyere 1211 when the filter member 13 is in the second position, so that dust on the filter member 13 can be cleaned by the cleaning brush when the filter member 13 is switched from the first position to the second position. In particular, the bristles of the brush are directed towards the filter element 13, so as to perform the cleaning of the filter element 13. A dust collecting groove is arranged below the cleaning brush, and dust cleaned by the cleaning brush falls into the collecting groove. Therefore, dust in the filter element 13 is cleaned in the process of switching once and again, and the air cleanness of the air conditioner ventilation assembly during operation is improved.

Specifically, in one embodiment, as shown in fig. 1 and 3, one of the air ports 1211 at both ends of the air duct 121 is located on the side surface 122 of the ventilation assembly body 12, and the other is located on the bottom surface 123 of the ventilation assembly body 12. Therefore, in the heating mode, the air opening 1211 located on the bottom surface 123 can be switched to the air outlet state, and the air opening 1211 located on the side surface 122 can be switched to the air inlet state, so that hot air can be diffused downwards well, and the heating effect is improved. In the cooling mode, the air inlet 1211 located on the bottom surface 123 is switched to an air inlet state, and the air inlet 1211 located on the side surface 122 is switched to an air outlet state, so that cold air is prevented from directly blowing to people, and cooling comfort is improved.

Further, in one embodiment, as shown in fig. 1 and 3, the filter member 13 can be switched between the first position and the second position at the tuyere 1211 by providing the filter member 13 and the driving member 11 and the connection transmission structure between the filter member 13 and the driving member 11 at both of the two tuyeres 1211. The air conditioner improves the cooling and heating comfort, and simultaneously avoids the dust from blowing into the room to influence the health of users. It should be noted that, when the two air ports 1211 of the air duct 121 are provided with the filter member 13 and the driving member 11, the specific structural forms and transmission forms of the filter member 13 and the driving member 11 provided at the two air ports 1211 may be different. For example, a driving member 11 provided with a tuyere 1211 directly drives the filtering member 13 to rotate by rotating to realize the switching between the first position and the second position; the other tuyere 1211 converts the rotation of the driving member 11 into the movement of the filtering member 13 by further providing the above-mentioned transmission member 14 through the transmission member 14, thereby realizing the switching of the filtering member 13 between the first position and the second position.

Further, in yet another embodiment, an air conditioning system is provided, including the air conditioning ventilation assembly 10 described above.
