It should be understood that the air conditioner further comprises an air conditioner external unit, the air conditioner external unit further comprises a condenser, a compressor and other components, wherein the compressor and the condenser can be arranged in the air conditioner external unit, the compressor is a core component of the air conditioner, the compressor can compress the coolant to form high-temperature high-pressure gaseous coolant, the condenser is cooling equipment of the air conditioner, the condenser is communicated with the compressor, the air conditioner compressor compresses the coolant to form high-temperature high-pressure gaseous coolant, the high-temperature high-pressure coolant enters the condenser, heat dissipation is completed in the condenser to form normal-temperature high-pressure coolant, then the normal-temperature high-pressure coolant enters the evaporator 220 of the fresh air conditioner through a pipeline, and the normal-temperature high-pressure coolant releases pressure in the evaporator to form normal-pressure gas, so that the low-temperature coolant can absorb indoor heat to achieve the purpose of reducing indoor environment temperature. The heating mode of the air conditioner is similar to the principle of the above-mentioned cooling mode, and will not be described again.
The housing 100 is further provided with a fresh air duct 140, one end of the fresh air duct 140 is connected with the fresh air module 300, the other end of the fresh air duct 140 is provided with a second fresh air port 144, the second fresh air port 144 is communicated with the air outlet 130 of the housing 100, the fresh air module 300 can input fresh air into the fresh air duct 140, and the fresh air is output to the indoor environment through the second fresh air port 144 and the air outlet 130 of the housing 100 so as to supplement the fresh air to the indoor environment. The fresh air duct 140 of the casing 100 may be further communicated with the air conditioning duct 110 of the casing 100 through the first fresh air port, so that after the fresh air module 300 inputs fresh air into the fresh air duct 140, the fresh air may also enter the air conditioning duct 110, so that the fresh air may exchange heat with the evaporator 220 of the air conditioning module 200, and the fresh air is heated or cooled and then is discharged from the air outlet 130 of the casing 100, so that the air quality of the cooled or heated air output by the air conditioner using the fresh air conditioner of the present application is high.
Specifically, when the outdoor environment temperature is higher, the indoor temperature is relatively lower when the air conditioner is in the refrigeration mode, and the fresh air module 300 passes the air with the outdoor temperature higher and then inputs the air into the indoor through the fresh air duct 140, the temperature of the fresh air is higher, and the indoor temperature is influenced, so that the refrigeration efficiency of the air conditioner is influenced. Therefore, the fresh air can be cooled by the evaporator 220 after entering the air conditioning duct 110 through the fresh air duct 140 of the casing 100, so that the fresh air conditioner can output the cooled fresh air, and the indoor air quality can be improved under the condition of changing the indoor environment temperature, and the indoor environment temperature can reach the preset temperature more efficiently under the condition of inputting the fresh air into the indoor environment, or the fluctuation of the indoor environment temperature can be reduced under the condition that the indoor environment temperature reaches the preset temperature.
The switching assembly 400 of the present application may be disposed in the fresh air duct 140 of the housing 100, where the switching assembly 400 is configured to controllably open the second fresh air port 144 of the fresh air duct 140 of the housing 100 or close the second fresh air port 144 of the fresh air duct 140 of the housing 100. When the switching assembly 400 closes the second fresh air port 144 of the fresh air duct 140 of the housing 100, the fresh air cannot be discharged through the second fresh air port 144 of the fresh air duct 140 of the housing 100, so that the fresh air input into the fresh air duct 140 of the housing 100 can be completely sucked into the air conditioning duct 110 by the fan 210 of the air conditioning module 200, so that the fresh air can exchange heat with the evaporator 220 to output the heated or cooled fresh air through the air outlet 130 of the housing 100.
When the switching assembly 400 opens the second fresh air port 144 of the fresh air duct 140 of the housing 100, fresh air can be output through the second fresh air port 144 of the fresh air duct 140, and since the second fresh air port 144 of the fresh air duct 140 is communicated with the air outlet 130 of the housing 100, fresh air output by the second fresh air port 144 of the fresh air duct 140 can be directly output to the indoor environment through the air outlet 130 of the housing 100, so that fresh air can be more efficiently input to the indoor environment. Specifically, when the indoor environment temperature is suitable, and the indoor and outdoor temperature difference is less, the fresh air conditioner of this application can only start the fresh air function and take a breath in the room, so the empty module of this application can set up to be in the state of closing, and the fresh air module 300 is to the fresh air duct 140 in this moment the fresh air that inputs to can be discharged through the second fresh air mouth 144 of fresh air duct 140, and then exports to indoor through the air outlet 130 of casing 100.
In the fresh air conditioner control method provided by the embodiment of the application, the air conditioner module 200 is disposed in the housing 100, the air conditioner module 200 can suck air outside the housing 100 and input the sucked air into the indoor environment after heat exchange, the fresh air module 300 is communicated with the fresh air duct 140 in the housing 100, when the switching assembly 400 seals the second fresh air port 144 of the fresh air duct 140, the fresh air entering the fresh air duct 140 can enter the air conditioner duct 110 to exchange heat with the air conditioner module 200, so that the fresh air after heating or cooling is input into the indoor environment through the air outlet 130 of the housing 100, and the influence of the fresh air on the indoor environment temperature is reduced under the condition that the air conditioner module 200 is started. After the switching assembly 400 opens the second fresh air port 144 of the fresh air duct 140, the fresh air input into the fresh air duct 140 by the fresh air module 300 can be directly input into the room through the second fresh air port 144 and the air outlet 130 of the housing 100, so that the fresh air can be more efficiently input into the indoor environment, and the ventilation efficiency of the indoor environment is higher.
In some embodiments, in order to make the fresh air conditioner of the present application more efficient in inputting fresh air into the indoor environment, and further make the fresh air efficiency of the fresh air conditioner of the present application better, the switching component 400 of the present application is configured to be capable of communicating the fresh air duct 140 of the housing 100 with the air conditioner duct 110 through the first fresh air port, or communicating the fresh air duct 140 with the second fresh air port 144. Specifically, when the air conditioning module 200 and the fresh air module 300 of the present application are both in the activated state, the switching assembly 400 communicates the fresh air duct 140 of the housing 100 with the air conditioning duct 110, and the second fresh air port 144 of the fresh air duct 140 is in the closed state, and at this time, the fresh air in the fresh air duct 140 can only enter the air conditioning duct 110, so that the fresh air can exchange heat with the evaporator 220 of the air conditioning module 200. And when the air conditioning module 200 of the present application is in a closed state, i.e. under the condition that the indoor environment temperature is not required to be adjusted, the switching component 400 can cut off the fresh air duct 140 of the housing 100 from the air conditioning duct 110, so that fresh air in the fresh air duct 140 cannot enter the air conditioning duct 110, and further, fresh air in the fresh air duct 140 can only be output through the second fresh air port 144 of the fresh air duct 140 and then be output to the indoor environment through the air outlet 130 of the housing 100. Through cutting off the fresh air duct 140 of the shell 100 and the air conditioning duct 110, part of fresh air can be prevented from flowing into the air conditioning duct 110, so that fresh air in the fresh air duct 140 can be more efficiently input into the indoor environment, and the ventilation efficiency of the fresh air conditioner of the application is improved.
Of course, in other embodiments, in order to simplify the structure of the fresh air conditioner of the present application, under the condition that the fresh air conditioner of the present application only needs to output fresh air indoors, the switching component 400 may be set to make the fresh air duct 140 of the casing 100 communicate with both the air conditioning duct 110 and the second fresh air duct 144, so that fresh air in the fresh air duct 140 may be output from the second fresh air duct 144 to the indoor environment through the air outlet 130 of the casing 100, and when fresh air in the fresh air duct 140 is input into the air conditioning duct 110, the fresh air may still be output to the indoor environment through the air outlet 130 of the casing 100, so that the functional setting of the switching component 400 is relatively single, and only needs to implement the function of opening and closing the second fresh air duct 144, thereby making the structure of the switching component 400 relatively simple, and further simplifying the structure of the fresh air conditioner of the present application and reducing the preparation cost.
In some embodiments, in order to make the temperature control of fresh air by the fresh air conditioner control method of the present application more accurate, in the direction from the air inlet 120 to the air outlet 130, the fan 210 and the evaporator 220 are sequentially disposed, and the first fresh air inlet includes a first opening 141a and a second opening 142a that are controlled to be opened and closed by the switching assembly 400, where the first opening 141a may be in communication with an air inlet side of the fan 210, and the second opening 142a may be in communication with a windward side of the evaporator 220 and located between the fan 210 and the evaporator 220. When fresh air enters the air conditioning duct 110 through the first opening 141a, the fresh air can exchange heat with the evaporator 220 sufficiently, so that the effect of controlling the temperature of the indoor environment is stronger after the fresh air is input indoors. When fresh air enters the air conditioning duct 110 through the second opening 142a, the fresh air can quickly contact with the evaporator 220 for heat exchange, so that the fresh air can quickly enter the indoor environment, and the fresh air is heated or cooled to a certain degree, so that the efficiency of improving the carbon dioxide concentration of the indoor environment is higher.
Specifically, the second opening 142a may be in communication with a windward side of the evaporator 220 such that fresh air output through the second opening 142a may directly contact the evaporator 220 for heat exchange.
In some embodiments, the fresh air duct 140 of the present application is configured to include a first channel 141 and a second channel 142, one end of the first channel 141 is communicated with the air outlet end of the fresh air module 300, the other end of the first channel 141 is communicated with both the second channel 142 and the fresh air duct 140, and the second fresh air port 144 of the fresh air duct 140 is disposed at one end of the second channel 142 opposite to the first channel 141, so that fresh air output by the fresh air module 300 can enter the first channel 141 first. The switching assembly 400 may be disposed in the first channel 141, and the switching assembly 400 may enable the first channel 141 to communicate with the air-conditioning duct 110, or enable the first channel 141 to communicate with the second channel 142, and when the first channel 141 communicates with the air-conditioning duct 110 and the first channel 141 is disconnected from the second channel 142, fresh air in the first channel 141 may enter into the air-conditioning duct 110 to exchange heat with the evaporator 220 of the air-conditioning module 200. When the first channel 141 is disconnected from the air conditioning duct 110 and the first channel 141 is communicated with the second channel 142, the fresh air in the first channel 141 can enter the second channel 142 and be directly output to the indoor environment through the second fresh air inlet 144 of the second channel 142 and the air outlet 130 of the housing 100.
The fresh air module 300 inputs fresh air into the first channel 141 of the fresh air duct 140, and the fresh air flow gradually becomes stable in the process of flowing in the first channel 141, so that the fresh air flow input into the air conditioning duct 110 and the second channel 142 through the first channel 141 is stable. In addition, since the first channel 141 and the second channel 142 are both located in the housing 100, and the air conditioning duct 110 is also located in the housing 100, the connection between the first channel 141 and the air conditioning duct 110 can be arranged adjacent to the fan 210 of the air conditioning module 200 by arranging the first channel 141, so that the fresh air in the first channel 141 can be more efficiently sucked into the air conditioning duct 110 by the fan 210 of the air conditioning module 200, and the arrangement mode of each part in the housing 100 of the fresh air conditioner of the application is more flexible.

Specifically, in the case that the switching assembly 400 is not disposed in the fresh air conditioner of the present application, the first channel 141, the air conditioning duct 110 and the second channel 142 are all in a communication state, and when the switching assembly 400 is disposed in the first channel 141, and the driving portion 410 drives the baffle 420 to block the air conditioning duct 110, the first channel 141 and the second channel 142 are still in a communication state, so that fresh air input into the first channel 141 by the fresh air module 300 can enter into the second channel 142. Under the condition that the driving portion 410 drives the baffle 420 to block the second channel 142, the first channel 141 is still in communication with the air conditioning duct 110, so that the fresh air input into the first channel 141 by the fresh air module 300 can enter into the air conditioning duct 110.

One end of the baffle plate is rotatably connected with the side wall of the first channel 141 provided with the first opening 141a, the driving part 410 can drive the baffle plate 420 to rotate along a first direction relative to the side wall of the first channel 141 provided with the first opening 141a, so that the baffle plate 420 can rotate to seal the first opening 141a of the first channel 141, and when the driving part 410 drives the baffle plate 420 to rotate along a second direction opposite to the first direction, the baffle plate 420 can seal the third opening 141b at the end part of the first channel 141.
When the fresh air conditioner of the present application is horizontally installed in a room, the first opening 141a of the first channel 141 may be opened on a side wall of the bottom of the first channel 141, and accordingly, the baffle 420 may be rotatably connected with the side wall of the bottom of the first channel 141, the driving portion 410 drives the baffle 420 to rotate toward the side wall of the bottom of the first channel 141, so that the baffle 420 may be blocked by the first opening 141a, and when the driving portion 410 drives the baffle 420 to rotate along a direction away from the side wall of the bottom of the first channel 141, the baffle 420 may be gradually erected in the first channel 141, so as to achieve the purpose of blocking the third opening 141b of the end of the first channel 141. Meanwhile, the specific location of the first opening 141a of the first channel 141 is not limited in this application, as long as the first opening 141a is opened on the sidewall of the first channel 141.
Furthermore, it should be further understood that when the first opening 141a and the third opening 141b of the first channel 141 are respectively opened at the side wall and the end of the first channel 141, the first opening 141a and the third opening 141b may be distributed at different sides of the first channel 141. Specifically, only the third opening 141b is disposed at the end of the first channel 141, so that the end of the first channel 141 is directly abutted with the second channel 142, and accordingly, the inner diameter of the fresh air channel 140 is kept consistent in the direction from the first channel 141 to the second channel 142, and the extending direction of the fresh air channel 140 is consistent.
In other embodiments, the driving portion 410 in the switching assembly 400 of the present application may further enable the baffle 420 to block the air-conditioning duct 110 or the second duct 142 by driving the baffle 420 to move, specifically, in this application, the first opening 141a and the third opening 141b of the first duct 141 may be disposed at an end portion of the first duct 141 or on a side wall of the first duct 141, and the first opening 141a and the third opening 141b of the first duct 141 may be distributed along a preset direction, and the driving portion 410 may drive the baffle 420 to reciprocate along the preset direction, so that the baffle 420 may selectively block the first opening 141a or the third opening 141b, so that the switching assembly 400 may also achieve the purpose of controlling the opening and closing of the air-conditioning duct 110 and the second duct 142.

It should be further understood that after the fresh air is input into the air conditioning duct 110 through the first opening 141a of the first channel 141, the fresh air amount in the portion of the air conditioning duct 110 adjacent to the first opening 141a of the first channel 141 may be larger than other areas of the air conditioning duct 110, so that when the fresh air is input into the air conditioning duct 110 through the first opening 141a of the first channel 141, the first opening 141a of the first channel 141 may be disposed at a middle position of the air conditioning duct 110, the fresh air output through the first opening 141a of the first channel 141 may be located at a middle portion of the air conditioning duct 110, and then the fresh air may be diffused into each portion of the air conditioning duct 110, so that the fresh air may be fully contacted with the evaporator 220 of the air conditioning module 200, thereby avoiding that the fresh air cannot be fully heated or cooled.
