The ventilation module 200 comprises a fresh air shell 210, a fan 220, a fresh air switch door 230 and an exhaust switch door 240 movably mounted on the fresh air shell 210, a ventilation air duct 211 is defined in the fresh air shell 210, the fan 220 is mounted in the ventilation air duct 211, a ventilation port 212 communicated with the ventilation air duct 211, a fresh air inlet 213 communicated with an air inlet end of the ventilation air duct 211 and an exhaust outlet 214 communicated with an air outlet end of the ventilation air duct 211 are formed in the fresh air shell 210, and the fresh air switch door 230 is used for opening or closing the fresh air inlet 213; the discharge opening and closing door 240 serves to open or close the discharge outlet 214. One end of the air exchange tube 300 is communicated with the air exchange port 212, and the other end is communicated with the indoor fresh air duct.
In the present embodiment, the air-conditioning indoor unit 100 may be a wall-mounted air-conditioning indoor unit 100, a floor-mounted air-conditioning indoor unit 100, or the like. Indoor unit 100 of air conditioner includes the indoor shell, prescribes a limit to heat transfer wind channel and indoor new trend wind channel in the indoor shell, then indoor new trend wind channel can be independent of the heat transfer wind channel, perhaps communicates in the heat transfer wind channel. In some embodiments, the indoor fresh air duct may also be a part of the heat exchange air duct, that is, the fresh air is blown out to the indoor through the heat exchange air duct 211, and then the heat exchanger may also be used to heat the fresh air. The ventilation module 200 may be embedded in a wall, hung on an external wall, or mounted on the outdoor unit 400 of the air conditioner. Through installing the module of taking a breath 200 in outdoor or wall body, then compare and install the module of taking a breath 200 in indoor side, can not occupy indoor extra space or receive the restriction of the machine body size of indoor set 100 of air conditioning to make the size of the module of taking a breath 200 can be done greatly, and then can promote the amount of wind. Meanwhile, the ventilation module 200 is installed outdoors or in a wall body, and the rotating speed of the motor of the fan 220 can be reduced under the condition that the whole air volume is not changed, so that the indoor air duct noise can be reduced or avoided under the condition of high air volume. In other words, under the condition that the whole noise is not changed, the air quantity of the whole air duct is improved, the air exchange efficiency is further improved, and the air exchange requirement is met.
The ventilation port 212 is connected with the ventilation tube 300 in a sealing way, the ventilation port 212 is generally circular, and a pipe joint can be arranged at the ventilation port 212 for the convenience of connecting the ventilation port. The shape of the fresh air inlet 213 and the exhaust air outlet 214 may be circular, or may be adaptively adjusted according to the shape of the fresh air shell 210, for example, rectangular, or original arc. The fresh air switch is matched with the fresh air inlet 213, the exhaust switch door 240 is matched with the exhaust outlet 214 in shape, so that the corresponding opening can be opened or closed. The fan 220 may be specifically a centrifugal fan 220, or may be a cross-flow fan 220, and in order to increase the overall air volume, the fan 220 is preferably a centrifugal fan 220. It is understood that the fan 220 is installed in the ventilation air duct 211, such that the ventilation air duct 211 has an air inlet end and an air outlet end. The fresh air inlet 213 is communicated with the air inlet end of the ventilation air duct 211, so that the fan 220 drives the air flow to flow into the ventilation air duct 211 through the fresh air inlet 213. The air outlet 214 is communicated with the air outlet end of the ventilation air duct 211, and the fan 220 drives the air flow in the ventilation air duct 211 to be discharged to the outside from the air outlet 214. The fresh air switch door 230 and the exhaust air switch door 240 are movably installed at the fresh air case 210. The fresh air switch door 230 and the exhaust air switch door 240 may be rotatably connected to the fresh air casing 210 or slidably connected to the fresh air casing 210 to rotatably or slidably open the fresh air inlet 213 and the exhaust air outlet 214. The fresh air switch door 230 and the exhaust air switch door 240 can be manually switched to open or close the fresh air inlet 213 and the exhaust air outlet 214, or can be driven by a driving device, such as a driving motor, to open or close the fresh air inlet 213 and the exhaust air outlet 214.
One end of the ventilation pipe 300 is communicated with the ventilation port 212, and the other end is communicated with the indoor fresh air duct, so that the airflow in the ventilation air duct 211 of the fresh air shell 210 can be blown into the ventilation pipe 300 through the ventilation port 212, and further blown into the room through the indoor fresh air duct; the indoor air flow can also enter the ventilation pipe 300 from the indoor fresh air duct and then blow into the ventilation air duct 211 of the fresh air shell 210 through the ventilation port 212. It can be understood that the fresh air switch door 230 and the exhaust air switch door 240 are controlled independently, and then usually when the fresh air switch door 230 opens the fresh air inlet 213, the exhaust air switch door 240 is controlled to close the exhaust air outlet 214, and the fan 220 drives the outdoor air flow to flow into the ventilation air duct 211 through the fresh air inlet 213, and then flow into the indoor fresh air duct through the ventilation opening 212 to blow into the room, so as to provide fresh air for the room. When the fresh air exhaust switch door 240 opens the air exhaust outlet 214, the fresh air switch door 230 is controlled to close the fresh air inlet 213, and the fan 220 drives the indoor dirty air to flow into the air exchange duct 211 through the indoor fresh air duct, the air exchange tube 300 and the air exchange port 212, and then to be exhausted through the air exhaust outlet 214, so as to exhaust the indoor dirty air. So, only through single scavenge pipe 300 and single fan 220, alright realize the switching of the new trend mode of module 200 of taking a breath and blowdown wind mode, practiced thrift a fan 220, simple structure for module 200 of taking a breath overall structure is compacter, occupation space is littleer, and easily realizes. The heat exchange function of the air conditioner and the fresh air or sewage function of the ventilation module 200 may be used simultaneously or independently. Can realize the free switching of new trend mode and blowdown wind mode according to the use scene of difference, satisfy user's diversified demand.
In the present invention, the ventilation module 200 is installed in the outdoor or wall, and thus, compared with the case where the ventilation module 200 is installed in the indoor, the present invention does not occupy an extra space in the indoor or is limited by the size of the body of the indoor unit 100 of the air conditioner, so that the size of the ventilation module 200 can be increased, and thus, the air volume can be increased. Meanwhile, the ventilation module 200 is installed outdoors or in a wall body, and the rotating speed of the motor of the fan 220 can be reduced under the condition that the whole air volume is not changed, so that the noise of the indoor ventilation air duct 211 can be reduced or avoided under the condition of high air volume. In other words, under the condition that the overall noise is not changed, the air volume of the overall ventilation air duct 211 is improved, the air exchange efficiency is further improved, and the air exchange requirement is met. In addition, the fresh air inlet 213 is opened or closed by the fresh air switch door 230, the exhaust outlet 214 is opened or closed by the exhaust switch door 240, the scavenging port 212 and the indoor fresh air duct are communicated by the scavenging duct 300, the fresh air mode and the blowdown air mode of the scavenging module 200 can be switched only by the single scavenging duct 300 and the single fan 220, one fan 220 is saved, the structure is simple, the overall structure of the scavenging module 200 is more compact, the occupied space is smaller, and the scavenging module is easy to realize.
Specifically, referring to fig. 3 to 7, the fresh air inlet 213 and the exhaust air outlet 214 are alternatively opened, when the fresh air inlet 213 is opened, the fan 220 is used to drive the outdoor airflow to enter the ventilation air duct 211 from the fresh air inlet 213 and blow to the indoor fresh air duct through the ventilation port 212, and the ventilation port 212 is located downstream of the exhaust air outlet 214; when the exhaust outlet 214 is opened, the fan 220 is used to drive the indoor airflow to enter the ventilation air duct 211 through the ventilation opening 212 and to be exhausted from the exhaust outlet 214, and the ventilation opening 212 is located upstream of the fresh air inlet 213.
In this embodiment, the fresh air inlet 213 and the exhaust air outlet 214 are selectively opened, so that the exhaust air outlet 214 is opened by the exhaust air switch door 240 when the fresh air switch door 230 closes the fresh air inlet 213, and the exhaust air outlet 214 is closed by the exhaust air switch door 240 when the fresh air switch door 230 opens the fresh air inlet 213. It is understood that the air conditioner has a fresh air mode and a blow-down air mode. When the air conditioner is in a fresh air mode, the fresh air inlet 213 is opened by the fresh air switch door 230, the exhaust outlet 214 is closed by the exhaust switch door 240, the fan 220 drives outdoor airflow to enter the ventilation air duct 211 from the fresh air inlet 213, and the outdoor airflow is blown to the indoor fresh air duct through the ventilation port 212 and finally blown into the room, so that fresh air is introduced into the room. On this flow path, the ventilation opening 212 is located downstream of the exhaust outlet 214. When the air conditioner is in the air exhaust mode, the air exhaust switch door 240 opens the air exhaust outlet 214, the fresh air switch door 230 closes the fresh air inlet 213, and the fan 220 drives the indoor air flow to enter the ventilation air duct 211 through the ventilation opening 212 and to be exhausted from the air exhaust outlet 214. In this flow path, the ventilation opening 212 is located upstream of the fresh air inlet 213. Thus, the ventilation opening 212 is specifically located between the exhaust air outlet 214 and the fresh air inlet 213, that is, between the air inlet end and the air outlet end of the ventilation air duct 211. The ventilation opening 212 can be used for exhausting fresh air when the fresh air inlet 213 is opened and the exhaust air outlet 214 is closed, or can be used for introducing indoor air when the fresh air inlet 213 is closed and the exhaust air outlet 214 is opened. Therefore, the fresh air mode and the sewage air mode of the whole ventilation module 200 are switched more smoothly and easily controlled.
In one embodiment, as shown in fig. 5 and 6, the ventilation air duct 211 defines a fan installation cavity 211a, a bypass air duct 211b and an air inlet air duct 211c, the air inlet air duct 211c communicates the fresh air inlet 213 with the air inlet end of the fan installation cavity 211a, the bypass air duct 211b communicates the ventilation opening 212 with the air inlet end of the fan installation cavity 211a, and the fresh air switch door 230 is disposed at the air flow openings of the bypass air duct 211b and the air inlet air duct 211c, so that the bypass air duct 211b and the air inlet air duct 211c can be selectively communicated with the air inlet end of the fan installation cavity 211 a.
In this embodiment, it can be understood that the ventilation air duct 211 is a complete flow channel, and the fan installation cavity 211a, the bypass air duct 211b and the air inlet air duct 211c are divided by a wall surface formed by the shape of the scroll 215. The fan 220 is installed in the fan installation cavity 211a, and the air inlet duct 211c forms an air inlet end of the ventilation air duct 211 to communicate the fresh air inlet 213 with the ventilation air duct 211 of the fan installation cavity 211 a. The air inlet end of the air exchanging port 212 and the air inlet end of the fan installation cavity 211a are communicated through the bypass air duct 211b, so that the air exchanging port 212 and the fresh air inlet 213 are both located at the air inlet end of the fan installation cavity 211 a. Thus, when the fresh air switch door 230 opens the air inlet duct 211c and blocks the bypass duct 211b, the airflow is introduced into the fan mounting cavity 211a through the fresh air inlet 213, and at this time, the ventilation port 212 is still connected to the air outlet end of the fan mounting cavity 211 a. When the fresh air switch door 230 closes the air inlet duct 211c and opens the bypass duct 211b, the air flow is introduced into the fan installation cavity 211a through the ventilation opening 212. Thereby enabling the ventilation module 200 to suck out dirty air from the indoor and introduce fresh air from the outdoor into the indoor. The fresh air switch door 230 is arranged at the gas flow openings of the bypass air duct 211b and the air inlet air duct 211c, so that when the fresh air switch door 230 opens the fresh air inlet 213, the bypass air duct 211b can be blocked, and the airflow is prevented from entering the fan installation cavity 211a from the bypass air duct 211 b; when the fresh air switch door 230 closes the fresh air inlet 213, i.e. blocks the air inlet duct 211c, the bypass duct 211b is opened, so that the air flow can enter the fan installation cavity 211a through the ventilation opening 212. Through setting up bypass wind channel 211b, and switch bypass wind channel 211b and air inlet wind channel 211c through new trend switch door 230, the structure is simpler and easily control on the one hand, and on the other hand makes the circulation passageway of scavenge port 212 different under new trend mode and the blowdown wind mode to make whole module 200 of taking a breath switch more smoothly under two kinds of modes, mutual noninterference. In other embodiments, the fresh air switch door 230 may be used to open or close the fresh air inlet 213 only, and a bypass switch door may be additionally provided to block or conduct the bypass air duct 211 b. And when the bypass air duct 211b is blocked, the ventilation port 212 is still conducted with the air outlet end of the fresh air installation cavity. So that the bypass switch door and the fresh air switch door 230 are alternatively opened.
Based on the above embodiments, referring to fig. 5 and fig. 6 again, the fresh air switch door 230 is rotatably installed on the fresh air casing 210 to rotatably switch the bypass air duct 211b or the intake air duct 211c to be communicated with the intake end of the fan installation cavity 211 a. The fresh air switch door 230 may be rotatably installed in the fresh air case 210 through a rotation shaft. Can be so that driving motor's drive shaft and new trend switch door 230 are connected to drive new trend switch door 230 rotates, and then realize switching bypass wind channel 211b and the air inlet end of installation cavity and switch on or air inlet wind channel 211c switches on with the air inlet end of installation cavity. The fresh air switch door 230 can be rotatably installed on the fresh air shell 210, so that the switching mode is simpler and is easy to realize.
Further, as shown in fig. 6 and 7, the fresh air casing 210 includes a volute 215, a ventilation air duct 211 is formed in the volute 215, and when the fresh air switch door 230 closes the fresh air inlet 213, the fresh air switch door 230 and a wall surface of the volute 215 are in smooth transition. When the fresh air switch door 230 closes the fresh air inlet 213, the ventilation module 200 is in the blowdown air mode, and the air flow flows into the air inlet end of the fan installation cavity 211a through the bypass air duct 211b from the ventilation port 212, and the fresh air inlet 213 is located at the upstream of the ventilation port 212.
