Detailed Description
The air conditioner often closes the door and window in the use, reduces indoor air conditioner or the warm air and dissipates to the outdoor, and current domestic air conditioner often is the inner loop, and air conditioner self can not exchange indoor air with outdoor air. If gas exchange is not performed for a long period of time inside and outside the room, the air quality in the room is lowered, such as an increase in carbon dioxide concentration and an increase in harmful organic volatile concentration. In the related art, an air conditioner with a fresh air function can introduce outdoor fresh air through a fresh air device to improve indoor air quality. However, the existing fresh air device has single function, and only introduces fresh air, so that the effect of improving the air quality is difficult to further improve.
In order to improve the defects in the prior art, the embodiment of the application provides a fresh air device which can realize the fresh air function of introducing fresh air into a room and the pollution discharge function of discharging indoor gas to the outside through one fan blade.
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

In this embodiment, the first chamber 120 is provided with a first support plate 116 and a second support plate 117 on two opposite inner walls in the first direction, wherein the second support plate 117 is disposed on the partition 112, two ends of the fresh air filter 150 are respectively connected to the first support plate 116 and the second support plate 117, and the first support plate 116, the fresh air filter 150 and the second support plate 117 jointly partition the first chamber 120 into a first region 121 and a second region 122. As shown in fig. 3, the upper region of the fresh air filter 150 and the first support plate 116 is the first region 121, and the lower left region of the fresh air filter 150 is the second region 122.
Further, the first support plate 116 is different from the second support plate 117 in position in the second direction, and the first support plate 116 is higher than the second support plate 117. The fresh air filter 150 is plate-shaped and inclined to the first and second directions. In the first direction, the end of the fresh air filter 150 connected to the second support plate 117 is closer to the partition 112 than the end of the fresh air filter 150 connected to the first support plate 116. The fresh air filter 150 is obliquely arranged, so that the filtering area can be increased, the filtering effect is improved, the fresh air filter 150 and the partition plate 112 form a tapered flow passage at the downstream of the first area 121, and the resistance to the introduction of the polluted air can be reduced.
Further, the projection of the fresh air filter 150 onto the partition 112 along the first direction covers at least 80% of the air intake 113. Since the air entering through the fresh air inlet 123 can only reach the first area 121 through the fresh air filter 150 and then reach the air guiding opening 113, the projection of the fresh air filter 150 on the partition board 112 covers at least 80% of the air guiding opening 113, so that the fresh air filter 150 is ensured to be large enough, the air inlet amount of the fresh air can be improved to a certain extent, and meanwhile, the filtering effect is also improved.
Further, the first support plate 116 and the second support plate 117 are slidably matched with the fresh air filter 150, and a first mounting opening is formed in the housing 110, and the first mounting opening is used for allowing the fresh air filter 150 to be drawn out of the first cavity 120 or be installed into the first cavity 120.

The following describes the operation of the fresh air device 100 in three different modes.
FIG. 6 is a second cross-sectional view of the fresh air device 100 in a fresh air mode according to one embodiment of the present application; fig. 7 is a third cross-sectional view of the fresh air device 100 in the fresh air mode according to an embodiment of the present application. As shown in fig. 3, 6 and 7, in the fresh air mode, the sliding door 126 closes the clean air outlet 124 and the dirty air outlet 125, the second rotary damper 173 opens the fresh air outlet 123, and the first rotary damper 172 opens the indoor air outlet 131 and closes the outdoor air outlet 132. When the fan blades 140 rotate, outdoor fresh air enters from the main valve opening 171 of the air valve 170, passes through the fresh air inlet 123, enters the first cavity 120, then passes through the fresh air filter 150, enters the second cavity 130, and finally is discharged into the room from the indoor air outlet 131. The hollow arrows in the figure indicate the flow direction of the air flow. In this process, since the outdoor air outlet 132 is blocked, fresh air does not directly enter the second chamber 130 from the outdoor air outlet 132 after entering the air valve 170.
FIG. 8 is a first cross-sectional view of the fresh air device 100 in a blowdown mode in one embodiment of the present application; FIG. 9 is a second cross-sectional view of the fresh air device 100 in a blowdown mode in one embodiment of the present application; fig. 10 is a third cross-sectional view of the fresh air device 100 in a blowdown mode in one embodiment of the present application. As shown in fig. 8 to 10, in the sewage discharge mode, the slide door 126 opens the sewage port 125 and closes the purge port 124, the fresh air port 123 is blocked by the second rotary damper 173, and the indoor air outlet 131 is blocked by the second rotary damper 173. When the fan blades 140 rotate, indoor air enters the first area 121 of the first cavity 120 from the air inlet 125, then enters the second cavity 130 directly from the air inlet 113, and then enters the exhaust section of the volute 119 under the action of the fan blades 140. At this time, since the first rotary damper 172 blocks the indoor air outlet 131, air enters the air valve 170 from the outdoor air outlet 132 and is then discharged to the outside from the main valve opening 171.
FIG. 11 is a first cross-sectional view of the fresh air device 100 in a purge mode in one embodiment of the present application; fig. 12 is a second cross-sectional view of the fresh air device 100 in a purge mode in one embodiment of the present application. As shown in fig. 11 and 12, in the purge mode, the slide door 126 opens the purge port 124 and closes the waste port 125, the fresh air port 123 is blocked by the second rotary damper 173, the outdoor air outlet 132 is blocked by the first rotary damper 172, and the indoor air outlet 131 is opened. After the fan blades 140 rotate, indoor air enters the first cavity 120 from the purifying opening 124, passes through the purifying filter 160 and the fresh air filter 150 in sequence, then enters the second cavity 130 through the air introducing opening 113, and is discharged into the room from the indoor air outlet 131. The indoor air is returned to the room after passing through the fresh air device 100 and is filtered twice in the process, so that it can be purified.

And the fresh air device 100 is disposed at one side of the air conditioning body 200 in the horizontal direction, and the first chamber 120, the second chamber 130, and the air conditioning body 200 are sequentially arranged. In other words, the first chamber 120, the second chamber 130, and the air conditioner main body 200 are sequentially arranged in the length direction of the air conditioner 010. Under this structure, the air inlet 125 and the purifying port 124 are located at a side of the fresh air device 100 away from the air conditioner main body 200, so that the air inlet is not easily affected by the induced air of the air inlet 210 at the upper side of the air conditioner main body 200 when the air is taken in, and the air inlet quantity of the air inlet 125 and the air inlet 124 is ensured.
In this embodiment, when the fresh air device 100 is normally installed in the air conditioner main body 200, the indoor air outlet 131 and the fresh air outlet 123 are located at a position below the fresh air device 100, and the indoor air outlet 131 and the air outlet 220 are arranged side by side in the horizontal direction, so that the fresh air outlet 123 is located below to be convenient for connecting an external fresh air pipe.
In this embodiment, an integrated panel may be disposed on the outer sides of the fresh air device 100 and the air conditioner main body 200, so that the fresh air device 100 and the air conditioner main body 200 are protected and the aesthetic degree is improved.
