It should be noted that the air valve mechanism can be designed according to actual needs, for example, the opening and closing of the air inlet 21, the first switching port 22, the air outlet 23 and the second switching port 24 are individually controlled by 4 valves. In some alternative embodiments, the air valve mechanism includes a first air valve assembly for opening and closing the air inlet 21 and the first switching port 22, and a second air valve assembly for opening and closing the air outlet 23 and the second switching port 24; the first air valve assembly includes a first baffle 41 rotatably connected to the housing 10 and a first power unit 42 driving the first baffle 41 to rotate, the first baffle 41 is located between the air inlet 21 and the first switching port 22, and the first baffle 41 rotates to close the air inlet 21 or the first switching port 22, so that the first baffle 41 can selectively close the air inlet 21 or the first switching port 22, because in the fresh air mode, the air exhaust mode, and the indoor cleaning mode, the air inlet 21 and the first switching port 22 are both closed and opened, the opening and closing of the two ports, i.e., the air inlet 21 and the first switching port 22, can be controlled by one baffle, thereby facilitating quick switching of air ducts and saving cost. And the second air valve assembly may be two valves for controlling the air outlet 23 and the second switching port 24 in a one-to-one correspondence manner.
In addition, in some alternative embodiments, the second air valve assembly may also include a second baffle 43 rotatably connected to the housing 10, and a second power unit 44 driving the second baffle 43 to rotate, where the second baffle 43 is located between the air outlet 23 and the second switching port 24, and the second baffle 43 rotates to close the air outlet 23 or the second switching port 24. The first baffle 41 can be used for selecting one closed air outlet 23 or one second switching port 24, because in the fresh air mode, the air exhaust mode and the indoor purification mode, the air outlet 23 and the second switching port 24 are both closed and opened, the opening and closing of the two ports of the air outlet 23 and the second switching port 24 can be controlled through one baffle, and therefore the switching of air channels can be realized quickly, and the cost is saved. In this case, the first air valve assembly may be two valves for controlling the air outlet 23 and the second switching port 24 in a one-to-one correspondence manner.
In addition, in some alternative embodiments, the first air valve assembly includes a first baffle 41 rotatably connected to the housing 10 and a first power unit 42 for driving the first baffle 41 to rotate, the first baffle 41 is located between the air inlet 21 and the first converting opening 22, and the first baffle 41 is rotated to close the air inlet 21 or the first converting opening 22; the second air valve assembly comprises a second baffle 43 rotatably connected with the shell 10 and a second power unit 44 driving the second baffle 43 to rotate, the second baffle 43 is located between the air outlet 23 and the second switching port 24, and the second baffle 43 rotates to close the air outlet 23 or the second switching port 24. The first baffle 41 of the first air valve assembly alternatively seals the air inlet 21 or the first switching port 22, and the second baffle 43 of the second air valve assembly alternatively seals the air outlet 23 or the second switching port 24.
In some alternative embodiments, an edge of at least one of the intake vent 21 and the first transfer port 22 is provided with a sealing connection portion 27, and the first baffle 41 abuts against the sealing connection portion 27 after rotating to seal the intake vent 21 or the first transfer port 22. In some alternative embodiments, an edge of at least one of the air outlet 23 and the second switching port 24 is provided with a sealing connection portion 27, and the first baffle 41 abuts against the sealing connection portion 27 after rotating to seal the air outlet 23 or the second switching port 24. The sealing connection portion 27 may be designed according to actual requirements, for example, the sealing connection portion 27 may be a gasket or a stepped portion, where the gasket may be an elastic rubber pad; in the present embodiment, the sealing connection portion 27 is a step portion, which not only can play a certain sealing role, but also can make the second baffle 43 stably and without shaking when the wind is discharged from the wind outlet 23 or the second switching port 24 out of the wind chamber 20, the second baffle 43 enters the step portion of the wind outlet 23 or the second switching port 24, so as to prevent the second baffle 43 from protruding from the inner surface of the housing and being blown by the wind. The sealing principle of the first baffle 41 and the sealing connection portion between the air inlet and the first converting port is the same, and is not described herein again.
In some alternative embodiments, the air chamber 20 includes a fan chamber 28 and a filter chamber 29 which are communicated with each other, the air inlet 21, the first transfer port 22 and the filter mechanism 26 are disposed in the filter chamber 29, the air outlet 23, the second transfer port 24 and the fan 25 are disposed in the fan 25 chamber, and the fan chamber 28 and the filter chamber 29 are separated separately to facilitate assembly and disassembly of different components. It should be noted that the structure of the housing 10 can be designed according to actual needs, so as to adjust the positions of the fan chamber 28, the filter chamber 29 and the switching duct 30 in the housing 10 to meet different functions. For example, in the present embodiment, the housing 10 includes a first case 11 and a second case 12 communicating with each other; the air chamber 20 comprises a fan 25 chamber and a filter chamber 29 which are communicated with each other, the fan 25 chamber is arranged in the first housing 11, the filter chamber 29 is arranged in the second housing 12, the switching air duct 30 is arranged in the first housing 11, the air inlet 21, the first switching port 22 and the filter mechanism 26 are arranged in the filter chamber 29, the air outlet 23, the second switching port 24 and the fan 25 are arranged in the fan 25 chamber, and the air chamber 20 is divided into two chambers, so that the air chamber 20 and the switching air duct 30 can be conveniently constructed by using the existing fan and filter mechanism self-contained shell assembly, and the structure of a fresh air system can be conveniently realized.
In some alternative embodiments, the filter mechanism 26 is removably attached to the inner wall of the plenum 20 to facilitate replacement of the filter mechanism 26, and the filter mechanism 26 is preferably a HEPA filter. In some embodiments, since the direction of the air inlet and the air inlet direction of the fan are not in the same direction, in order to increase the effective filtering area of the filtering mechanism 26 and avoid the filtering surface 26 of the filtering mechanism from being parallel to the air direction to reduce the filtering effect, the filtering surface of the filtering mechanism 26 may be set to have an included angle with the direction from the air inlet 21 to the air inlet end of the fan, for example, in this embodiment, a supporting platform 291 is disposed in the filtering chamber 29, the bottom of the filtering mechanism is connected to the supporting platform 291, the top of the filtering mechanism abuts against the inner wall of the filtering chamber 29, and the supporting platform 291 obliquely supports the filtering mechanism 26, so that the direction of the filtering mechanism 26 and the air inlet 21 and the air inlet direction of the fan 25 form an included angle.
In some optional embodiments, the casing 10 is preferably further provided with a thermal insulation material, which is beneficial to maintaining the temperature adjusting effect of the air conditioner.
