The invention provides an air conditioner.
In an embodiment of the present invention, as shown in fig. 1 to 7, the air conditioner includes an air conditioning indoor unit 100, a ventilation module 200, and a ventilation pipe 300. The air conditioning indoor unit 100 defines an indoor fresh air duct therein, and the ventilation module 200 is installed outdoors or in a wall. 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, wherein the fresh air switch door 230 and the exhaust switch door 240 are movably arranged on the fresh air shell 210, a ventilation air channel 211 is defined in the fresh air shell 210, the fan 220 is arranged in the ventilation air channel 211, a ventilation opening 212 communicated with the ventilation air channel 211, a fresh air inlet 213 communicated with an air inlet end of the ventilation air channel 211 and an exhaust outlet 214 communicated with an air outlet end of the ventilation air channel 211 are formed in the fresh air shell 210, the fresh air switch door 230 is used for opening or closing the fresh air inlet 213, and the exhaust switch door 240 is used for opening or closing the exhaust outlet 214. One end of the ventilation pipe 300 is communicated with the ventilation port 212, and the other end is communicated with an 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-type air conditioning indoor unit 100, or the like. The air conditioner indoor unit 100 includes an indoor housing, in which a heat exchange air duct and an indoor fresh air duct are defined, and the indoor fresh air duct may be independent of the heat exchange air duct or may be connected to the heat exchange air duct. In some embodiments, the indoor fresh air duct may also be made part of the heat exchange air duct, that is, the fresh air is blown out into the room through the heat exchange air duct 211, and then the fresh air may also be heated by using the heat exchanger. The ventilation module 200 may be embedded in a wall body, may be hung on an outer wall, and may be installed on the outdoor unit 400. By installing the ventilation module 200 outside or in a wall body, compared with installing the ventilation module 200 inside, the ventilation module 200 does not occupy additional space in the room or is limited by the size of the air conditioner indoor unit 100, so that the size of the ventilation module 200 can be increased, and the air quantity can be improved. Meanwhile, the ventilation module 200 is installed outdoors or in a wall body, and can reduce the motor rotation speed of the fan 220 under the condition that the whole air quantity is unchanged, so that the noise of an indoor air channel can be reduced or avoided under the condition of high air quantity. In other words, under the condition that the overall noise is unchanged, the air quantity of the overall air duct is improved, the air exchanging efficiency is further improved, and the air exchanging requirement is met.
The transfer port 212 is in sealed connection with the transfer tube 300, and the transfer port 212 is generally circular in shape, and a tube fitting may be provided at the transfer port 212 for ease of connection. 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 case 210, for example, rectangular, original arc, etc. The fresh air switch is matched with the fresh air inlet 213 in shape, and the exhaust switch door 240 is matched with the exhaust outlet 214 in shape, so that the corresponding opening is opened or closed. The fan 220 may be a centrifugal fan 220 or a cross-flow fan 220, and in order to improve the overall air volume, the fan 220 is preferably a centrifugal fan 220. It will be appreciated that the fan 220 is mounted within 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 channel 211, and then the fan 220 drives air flow to flow into the ventilation air channel 211 from the fresh air inlet 213. The exhaust 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 outdoors through the exhaust outlet 214. The fresh air opening and closing door 230 and the exhaust opening and closing door 240 are movably installed to the fresh air case 210. The fresh air opening and closing door 230 and the exhaust opening and closing door 240 may be rotatably connected to the fresh air case 210 or slidably connected to the fresh air case 210, so as to rotatably or slidably open the fresh air inlet 213 and the exhaust outlet 214. The fresh air opening and closing door 230 and the exhaust opening and closing door 240 can be manually switched to open or close the fresh air inlet 213 and the exhaust 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 outlet 214.
One end of the ventilation pipe 300 is communicated with the ventilation port 212, and the other end of the ventilation pipe 300 is communicated with the indoor fresh air channel, so that air flow in the ventilation air channel 211 of the fresh air shell 210 can be blown into the ventilation pipe 300 through the ventilation port 212 and then blown into a room through the indoor fresh air channel, and also can be blown into the ventilation air channel 300 through the indoor fresh air channel and then blown into the ventilation air channel 211 of the fresh air shell 210 through the ventilation port 212. It will be appreciated that the fresh air switch door 230 and the exhaust switch door 240 are independently controlled, and then when the fresh air switch door 230 opens the fresh air inlet 213, the exhaust switch door 240 is controlled to close the exhaust outlet 214, and the fan 220 drives the outdoor air flow to flow into the ventilation air duct 211 from the fresh air inlet 213, and then flow into the indoor fresh air duct from the ventilation opening 212, so as to blow into the room, thereby providing fresh air indoors. When the fresh air opening and closing door 240 opens the air exhaust outlet 214, the fresh air opening and closing door 230 is controlled to close the fresh air inlet 213, and the fan 220 drives indoor polluted air to flow into the ventilation air duct 211 through the indoor fresh air duct, the ventilation pipe 300 and the ventilation port 212, and then is discharged from the air exhaust outlet 214, so that indoor polluted air is realized. Therefore, the fresh air mode and the blow-down air mode of the ventilation module 200 can be switched by only a single ventilation pipe 300 and a single fan 220, one fan 220 is saved, and the ventilation module 200 is simple in structure, compact in overall structure, small in occupied space and easy to realize. The heat exchange function of the air conditioner and the fresh air or sewage air discharging function of the ventilation module 200 can be used simultaneously or independently. According to different use scenes, the free switching between the fresh air mode and the blow-down air mode can be realized, and the diversified demands of users are met.
According to the invention, by installing the ventilation module 200 outside or in a wall body, compared with installing the ventilation module 200 inside, the ventilation module 200 does not occupy extra space in the room 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 the air quantity can be improved. Meanwhile, the ventilation module 200 is installed outdoors or in a wall body, and the motor rotation speed of the fan 220 can be reduced under the condition that the whole air quantity is unchanged, so that the noise of the indoor ventilation air duct 211 can be reduced or avoided under the condition of high air quantity. In other words, under the condition that the overall noise is unchanged, the air quantity of the overall ventilation air duct 211 is improved, so that the air exchanging efficiency is improved, and the air exchanging requirement is met. In addition, by setting the fresh air switch door 230 to open or close the fresh air inlet 213 and the exhaust switch door 240 to open or close the exhaust outlet 214, the ventilation pipe 300 is adopted to communicate the ventilation port 212 with the indoor fresh air channel, and then the fresh air mode and the blowdown air mode of the ventilation module 200 can be switched only through the single ventilation pipe 300 and the single fan 220, so that one fan 220 is saved, the structure is simple, the whole structure of the ventilation module 200 is more compact, the occupied space is smaller, and the ventilation module is easy to realize.
Specifically, referring to fig. 3 to 7, when the fresh air inlet 213 is opened, the fan 220 is used to drive outdoor air to enter the ventilation duct 211 from the fresh air inlet 213 and blow to the indoor fresh air duct via the ventilation port 212, the ventilation port 212 is located at the downstream of the ventilation outlet 214, and when the ventilation outlet 214 is opened, the fan 220 is used to drive indoor air to enter the ventilation duct 211 via the ventilation port 212 and be discharged from the ventilation outlet 214, and the ventilation port 212 is located at the upstream of the fresh air inlet 213.
In this embodiment, when the fresh air inlet 213 is selectively opened to the air outlet 214, the air outlet 214 is opened by the air outlet switch door 240 when the fresh air inlet 213 is closed by the fresh air switch door 230, and the air outlet 214 is closed by the air outlet switch door 240 when the fresh air inlet 213 is opened by the fresh air switch door 230. It will be appreciated that the air conditioner has a fresh air mode and a blowdown air mode. When the air conditioner is in the fresh air mode, the fresh air switch door 230 opens the fresh air inlet 213, the exhaust switch door 240 closes the exhaust outlet 214, the fan 220 drives outdoor air flow to enter the ventilation air duct 211 from the fresh air inlet 213, and to blow into the indoor fresh air duct through the ventilation opening 212, and finally to blow into the indoor, so as to realize indoor fresh air introduction. On this flow path, the transfer ports 212 are located downstream of the exhaust outlets 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 indoor air flow to enter the ventilation air duct 211 through the ventilation opening 212 and is exhausted from the air exhaust outlet 214. In this flow path, the transfer port 212 is located upstream of the fresh air inlet 213. In this way, the ventilation opening 212 is specifically located between the exhaust outlet 214 and the fresh air inlet 213, that is, between the air inlet end and the air outlet end of the ventilation duct 211. The ventilation port 212 can be opened when the fresh air inlet 213 is opened and the exhaust outlet 214 is closed to discharge fresh air, or can be closed when the fresh air inlet 213 is closed and the exhaust outlet 214 is opened to introduce indoor air. So that the fresh air mode and the blow-down air mode of the whole ventilation module 200 are switched more smoothly and easily.
In an 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 is communicated with the fresh air inlet 213 and the air inlet end of the fan installation cavity 211a, the bypass air duct 211b is communicated with the ventilation opening 212 and the air inlet end of the fan installation cavity 211a, and the fresh air switch door 230 is arranged at the air circulation 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 are alternatively communicated with the air inlet end of the fan installation cavity 211 a.
In the present embodiment, it is understood that the ventilation air duct 211 is a complete flow path, and the fan installation cavity 211a, the bypass air duct 211b and the air intake air duct 211c are divided by the wall surface formed by the shape of the scroll casing 215. The fan 220 is installed in the fan installation cavity 211a, and the air inlet channel 211c forms an air inlet end of the ventilation air channel 211 so as to communicate the fresh air inlet 213 with the ventilation air channel 211 of the fan installation cavity 211 a. The bypass air channel 211b is used for communicating the ventilation opening 212 with the air inlet end of the fan installation cavity 211a, so that the ventilation opening 212 and the fresh air inlet 213 are both positioned at the air inlet end of the fan installation cavity 211 a. Thus, when the fresh air switch door 230 opens the air inlet channel 211c and blocks the bypass channel 211b, air flow is introduced into the fan installation cavity 211a through the fresh air inlet 213, and at this time, the ventilation port 212 is still communicated with the air outlet end of the fan installation cavity 211 a. And when the fresh air opening and closing door 230 closes the air inlet duct 211c and opens the bypass duct 211b, air flow is introduced into the fan installation cavity 211a through the ventilation port 212. So that the ventilation module 200 can suck out the indoor polluted air and introduce outdoor fresh air into the indoor. 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 when the fresh air switch door 230 opens the fresh air inlet 213, the bypass air duct 211b can be blocked to prevent air flow from entering the fan installation cavity 211a from the bypass air duct 211b, and when the fresh air switch door 230 closes the fresh air inlet 213, i.e. the air inlet air duct 211c is blocked, the bypass air duct 211b is opened, so that air flow can enter the fan installation cavity 211a through the ventilation opening 212. By arranging the bypass air channel 211b and switching the bypass air channel 211b and the air inlet air channel 211c through the fresh air switch door 230, on one hand, the structure is simpler and easy to control, and on the other hand, the ventilation channels of the ventilation ports 212 in the fresh air mode and the blow-down air mode are different, so that the whole ventilation module 200 is switched more smoothly in the two modes and is not interfered with each other. In other embodiments, the fresh air switch door 230 may be used to open or close the fresh air inlet 213, and a bypass switch door may be provided to block or conduct the bypass air channel 211b. And when the bypass air duct 211b is blocked, the ventilation port 212 is still communicated with the air outlet end of the fresh air installation cavity. So that the bypass switch door is selectively opened with the fresh air switch door 230.
Further, referring to fig. 5 and 6 again, the fresh air switch door 230 is rotatably mounted on the fresh air case 210 to rotatably switch the bypass air duct 211b or the air inlet air duct 211c to be connected with the air inlet end of the fan mounting cavity 211 a. The fresh air opening and closing door 230 may be rotatably installed to the fresh air case 210 through a rotation shaft.
