FIG. 2 illustrates an air conditioner with an air purifying function provided by some embodiments of the present disclosure. The air conditioner with the air purifying function includes a housing 1, an air inlet 11 and an air outlet 12 are disposed on the housing 1, and an air conditioning assembly 2 and an air purifying assembly 3 are disposed in the housing 1. The air conditioning assembly 2 includes an air conditioning flue 21. A first fan 22 and a heat exchanger 23 are disposed in the air conditioning flue 21, and the air conditioning flue 21 connects with the air inlet 11 and the air outlet 12 respectively. The air purifying assembly 3 includes an air purifying flue 31, a second fan 32 and an air filter screen 33 are disposed in the air purifying flue 31, and the air purifying flue 31 connects with the air inlet 11 and the air outlet 12 respectively.

Since the air conditioning assembly 2 is disposed in the housing 1, the air conditioning assembly 2 includes an air conditioning flue 21, a first fan 22 and a heat exchanger 23 are disposed in the air conditioning flue 21, and the air conditioning flue 21 connects with the air inlet 11 and the air outlet 12 respectively, therefore the air conditioner with an air purifying function provided by some embodiments of the present disclosure can realize a temperature regulation function. In addition, an air purifying assembly 3 is also disposed in the housing 1. The air purifying assembly 3 includes the air purifying flue 31, the second fan 32 and the air filter screen 33 are disposed in the air purifying flue 31, and the air purifying flue 31 connects with the air inlet 11 and the air outlet 12 respectively. Air can be introduced into the air filter screen 33 by the second fan 32 for filtration, thereby achieving the function of air purifying. Therefore, one air conditioner can have two functions of adjusting temperature and purifying air, which reduces cost and saves space.

The air conditioning flue 21 and the air purifying flue 31 can be arranged in series or in parallel.

When the air conditioning flue 21 and the air purifying flue 31 are connected in series, the structure is shown in FIG. 2. The air entering side of the air purifying flue 31 is connected to the air inlet 11, the air exiting side of the air purifying flue 31 is connected to the air entering side of the air conditioning flue 21, and the air exiting side of the air conditioning flue 21 is connected to the air outlet 12. When both the first fan 22 and the second fan 32 are turned on, air outside the housing 1 enters the housing 1 through the air inlet 11, and is sent out through the air outlet 12 after sequentially passing through the air filter screen 33, the second fan 32, an air deflector 13, the heat exchanger 23 and the first fan 22. In this case, the discharged air is filtered by the air filter screen 33 and heat-exchanged in the heat exchanger 23, thereby achieving the purposes of purifying air and adjusting temperature and humidity. Moreover, the structure only needs to provide an air inlet 11 and an air outlet 12 on the housing 1 to realize the air entering and exiting of the air conditioning flue 21 and the air purifying flue 31 simultaneously. Compared with the solution that the air conditioning flue 21 and the air purifying flue 31 are connected in parallel, the overall structure is simpler, and the transverse width is smaller. In addition, since the air conditioning flue 21 and the air purifying flue 31 are connected, the first fan 22 and the second fan 32 can simultaneously accelerate the air, thereby increasing the flow rate of the air. Moreover, the user can also select to turn on only one of the fan, and the functions of adjusting the temperature and purifying the air can also be realized, thereby meeting different working conditions.

It should be noted that, structures shown in FIGS. 2 to 7 are structural diagrams of the air purifying assembly 3 disposed at the upper side of the air conditioning assembly 2, and arrows in the figures indicate flow direction of the air. In some embodiments of the present disclosure, the air purifying assembly 3 can also be disposed at the lower side of the air conditioning assembly 2, so that the air entering side of the air conditioning flue 21 is connected to the air inlet 11. The air exiting side of the air conditioning flue 21 is connected to the air entering side of the air purifying flue 31, and the air exiting side of the air purifying flue 31 is connected to the air outlet 12. There is no limit here.

In order to rapidly adjust indoor temperature, as shown in FIG. 2, an air conditioner inlet 14 is disposed on the housing 1 at a position corresponding to the air conditioning assembly 2, so that the air conditioner inlet 14 is connected to the air entering side of the air conditioning flue 21. An air entering grating 15 is disposed at the air conditioner inlet 14, and the air entering grating can open or close the air conditioner inlet 14. Therefore, when it is necessary to rapidly adjust the indoor temperature, the air conditioner inlet 14 can be opened to increase the amount of air entering the air conditioning assembly 2, thereby accelerating the adjustment of the indoor temperature. When the indoor temperature meets the requirement, the air conditioner inlet 14 can be closed. As such, the amount of air entering the air conditioning assembly 2 can be reduced to stabilize the indoor temperature.

As shown in FIGS. 2 and 3, in order to expediently control the working forms of the air conditioning assembly 2 and the air purifying assembly 3 respectively. An auxiliary tuyere 16 can be disposed on the housing 1 at a position corresponding to the joint of the air conditioning flue 21 and the air purifying flue 31, and a ventilation door 17 is disposed at the auxiliary tuyere 16. Herein, the ventilation door 17 is switchable between a first position (the position of the ventilation door in FIG. 2) and a second position (the position of the ventilation door in FIG. 3). As shown in FIG. 2, when the ventilation door 17 is placed at the first position, the ventilation door 17 blocks the auxiliary tuyere 16, and the air conditioning flue 21 is connected to the air purifying flue 31. When the ventilation door 17 is placed at the second position, as shown in FIG. 3, the ventilation door 17 opens the auxiliary tuyere 16, and the air conditioning flue 21 is disconnected to the air purifying flue 31, so that the air exiting side of the air purifying flue 31 is connected the auxiliary tuyere 16. In this case, the amount of discharged air of the air conditioning assembly 2 and the air purifying assembly 3 can be separately controlled. For example, the amount of discharged air can be adjusted by adjusting rotating speed of the fans, so that the control form is more diversity to meet different needs of users.

In order to achieve the above functions, the ventilation door 17 can use a structure as shown in FIG. 3. The ventilation door 17 is hinged to the edge of a side of the auxiliary tuyere 16 close to the air conditioning flue 21. A lap plate 18 is disposed on a side wall in the housing 1 opposite to the side wall where disposed the ventilation door 17, and the ventilation door 17 is rotatable toward the inside of the housing 1. When the ventilation door 17 is rotated to the second position, as shown in FIGS. 3 and 4, the ventilation door 17 laps with the lap plate 18 to disconnect the air conditioning flue 21 and the air purifying flue 31. The structure is simple and easy to realize.

In some embodiments, the lap plate 18 can be provided in a stretchable structure. As shown in FIG. 4, a slot 19 can be disposed on a side wall in the housing 1 opposite to the side wall where disposed the ventilation door 17. The lap plate 18 is fitly inserted into the slot 19 and can slide relative to the slot 19 to change a length of the lap plate 18 extending into the housing 1. Therefore, when it is necessary to switch the ventilation door 17 to the second position, the lap plate 18 can be inserted into the housing 1 so that the length of the lap plate 18 within the housing 1 is extended to expediently lap with the ventilation door 17. Since the length of the lap plate 18 within the housing 1 is long enough, the ventilation door 17 does not need to be made too long, which facilitates the rotation of the ventilation door 17, and prevents the ventilation door 17 from interfering with other structures (such as the air deflector 13) within the housing 1 as the ventilation door 17 rotates. When it is necessary to switch the ventilation door 17 to the first position, as shown in FIG. 5, the lap plate 18 can be withdrawn from the housing 1 through the slot 19, thereby preventing the lap plate 18 that extends into the housing 1 from blocking the air in the air flue, which affects the amount of discharged air.

When setting the extending and contracting direction of the lap plate 18, in some embodiments, the extending direction of the lap plate 18 is disposed to be parallel to the extending direction of the air deflector 13 in the housing 1. Thereby, the lap plate 18 can also have an air guide effect, and reduce the blocking of the air by the lap plate 18.

In some embodiments of the present disclosure, as shown in FIG. 6, the ventilation door 17 can also be switched to a third position (the position of the ventilation door in FIG. 6). When the ventilation door 17 is switched to the third position, the ventilation door 17 can block the air conditioner inlet 14. Therefore, a static pressure difference can be generated between the inside and outside of the housing 1, so that a part of the purified air can enter the heat exchanger 23, and the other part of the purified air is sent into the room by the auxiliary tuyere 16. Meanwhile, the indoor air enters the heat exchanger 23 through the auxiliary tuyere 16 under the action of the static pressure difference to exchange heat, thereby realizing dual functions of purification and air conditioning, and accelerating the air purifying and air conditioning capabilities to the utmost extent.

In order to achieve the above functions, the air conditioner inlet 14 is disposed close to the hinged joint of the ventilation door 17. The ventilation door 17 is rotatable toward the outside of the housing 1. When the ventilation door 17 is rotated to the third position, the ventilation door 17 is attached to the outside wall of the air conditioner inlet 14 to block the air conditioner inlet 14.

In some embodiments of the present disclosure, as shown in FIG. 7, the ventilation door 17 can also be switched to a fourth position (position of the ventilation door in FIG. 7). When the ventilation door 17 is switched to the fourth position, the ventilation door 17 is located outside the housing 1 and is perpendicular to the outside wall of the housing 1 provided with the auxiliary tuyere 16. In this case, the ventilation door 17 neither blocks the auxiliary tuyere 16 and the air conditioner inlet 14, nor blocks the air of the air purifying flue 31 from entering the air conditioning flue 21, thereby maximizing the amount of air passing through the heat exchanger 23, so that the temperature and humidity of the air in the room can meet the requirement as quickly as possible.

In order to achieve the above functions, a window catch or other support limiting member (not shown) can be disposed between the ventilation door 17 and the outside wall of the housing 1 for supporting the ventilation door 17 to maintain the ventilation door 17 at the fourth position. It is also possible to design the ventilation door 17 to be detachably hinged with the housing 1. When the above functions need to be realized, the ventilation door 17 can be detached to make the air temperature and humidity of the room meet the requirement as quickly as possible, and realize the air conditioning function rapidly. Meanwhile, the air purifying function is achieved, so that the indoor indexes of PM2.5, temperature, humidity and the like of the room all meet requirements.

When the air conditioning flue 21 and the air purifying flue 31 are connected in parallel, the air conditioning flue 21 and air purifying flue 31 do not connected to each other, working separately. One fan can be used to simultaneously supply air to the air conditioning flue 21 and air purifying flue 31, or two fans can be respectively used to supply air.

As shown in FIG. 2, the heat exchanger 23 can be a V-shaped (two-fold structure) heat exchanger or a U-shaped (three-fold structure) heat exchanger. A portion of the heat exchanger 23 is located between the air conditioner inlet 14 and the air entering side of the fan, and another portion of the heat exchanger 23 is located between the air exiting side of the air purifying flue 31 and the air entering side of the fan. Thereby, heat exchange efficiency can be improved.

The first fan 22 and the second fan 32 are cross-flow fans. Compared with a centrifugal fan and an axial-flow fan, the cross-flow fan has a large air exiting amount and low noise. Specifically, the two cross-flow fans can be disposed in parallel as shown in FIG. 2. When two cross-flow fans arranged in parallel are connected in series, the two cross-flow fans are more matched to the acceleration effect of the wind, and the airflow is more stable and less turbulent.

The air filtering screen 33 is a high efficiency particle air filter (i.e. a HEPA filter). The HEPA screen can effectively filter and capture particles with diameters of 0.3 microns and more, with an efficiency of 99.7% or more. This has a better filtering effect.

In order to achieve some additional functions and bring the best comfort experience to users, as shown in FIG. 2, an additional functional module 4 can be disposed in the air purifying flue 31, such as a fragrance module, a nano-water ion module, an electronic sterilization module, or the like. The fragrance module can remove the peculiar smell of the indoor air. The nano-water ion is more suitable for the absorption of the human skin and can inhibit bacterium. The electronic sterilization module can sterilize. Therefore, the device can meet requirements of different users.

The foregoing descriptions are merely some specific implementation manners of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and the changes or replacements that any person skilled in the art can easily think of in the technical scope disclosed by the present disclosure should be within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be determined by the protection scope of the claims.
