[0002] The air conditioner includes an indoor unit and an outdoor unit. The indoor unit is usually installed indoors and can be used to exchange heat with indoor air. The outdoor unit is installed outdoors and can be used to exchange heat in the refrigerant with outdoor air.

[0003] The indoor unit of the air conditioner includes a casing, on which a heat exchange air inlet and a heat exchange air outlet are arranged. When heating and cooling, indoor air flows into the casing through the heat exchange air inlet and flows out through the heat exchange air outlet. The indoor unit of the air conditioner also includes a fresh air module, which is used to introduce outdoor air into the room through the fresh air outlet. The indoor unit of the air conditioner also includes a guide member, which is used to guide outdoor air into the room.

[0004] At present, the fresh air outlet of the guide piece is long, and there is a problem of air volume loss when the outdoor air flows in the guide piece. The air volume near the fresh air inlet in the guide piece is obviously greater than the air volume far away from the fresh air inlet. The farther away from the fresh air inlet, the greater the air volume loss, and the smaller the air volume reaching the fresh air outlet, resulting in uneven air outlet and uneven mixed air at the air outlet of the air conditioner.

[0005] After outdoor air is introduced into the room, condensation water will form when it encounters the inner wall of the guide piece. The condensation water will be blown into the room with the outdoor fresh air, affecting the user experience of the air conditioner indoor unit introducing outdoor fresh air. Utility Model Content

When cooling or heating, the indoor air flows into the first cavity through the heat exchange air inlet 31 and flows into the room through the heat exchange air outlet 32.

[0075] The main body may include an indoor heat exchanger 1001, which is disposed in the first cavity. The indoor heat exchanger 1001 is used to exchange heat with indoor air entering the first cavity.

[0076] In some embodiments, the main body may include a heat exchange fan, which is disposed in the first cavity. The heat exchange fan may be used to drive indoor air into the first cavity through the heat exchange air inlet 31, and then flow through the indoor heat exchanger 1001, and then flow into the room through the heat exchange air outlet 32. It may be arranged that the heat exchange fan is disposed on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to the air flow and increase the air intake into the room.

[0077] The heat exchange fan may include a motor and a fan. The driving shaft of the motor is connected to the fan. The fan is driven by the motor to rotate to drive the air in the first chamber to flow.

[0078] In some embodiments, the air conditioner outdoor unit 200 is disposed in an outdoor space, and the air conditioner outdoor unit 200 includes a housing, a second cavity is disposed in the housing, and an outdoor air inlet and an outdoor air outlet are disposed on the housing. The outdoor air inlet is connected to the outdoor space and the second cavity, and the outdoor air outlet is connected to the outdoor space and the second cavity.

[0079] In some embodiments, an outdoor heat exchanger 202 is disposed in the shell, and refrigerant flows in the outdoor heat exchanger 202 . The refrigerant in the outdoor heat exchanger 202 can be used to exchange heat with the air entering the second cavity and flowing through the outdoor heat exchanger 202 .

[0080] In some embodiments, a compressor 201 is disposed in the shell, the compressor 201 is disposed in the second chamber, and the compressor 201 is installed at the bottom of the air-conditioning outdoor unit 200 .

[0081] In some embodiments, the air-conditioning outdoor unit 200 may include a throttling device 204, which is disposed in the second cavity and is used to expand the liquid refrigerant in a high-temperature and high-pressure state into a low-pressure liquid refrigerant. The throttling device 204 may be disposed on the leeward side of the outdoor heat exchanger 202, and may be conveniently connected to the compressor 201.

[0082] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204 and the indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0083] The compressor 201 compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202 .

[0084] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0085] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0086] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201 .

[0087] The indoor heat exchanger 1001 can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0088] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one is a condenser and the other is an evaporator. When the indoor heat exchanger 1001 is used as a condenser and the outdoor heat exchanger 202 is used as an evaporator, the air conditioner 1000 is used as a heater in the heating mode. When the indoor heat exchanger 1001 is used as an evaporator and the outdoor heat exchanger 202 is used as a condenser, the air conditioner 1000 is used as a cooler in the cooling mode.

[0089] In some embodiments, the indoor unit of the air conditioner may include a fresh air volute 4 , which is disposed in the casing 3 , and the outdoor fresh air may flow into the room through the fresh air volute 4 .

[0090] In some embodiments, the fresh air volute 4 may include a first fresh air inlet 41 , and the first fresh air inlet 41 may be connected to the outdoor space through a fresh air duct. Outdoor air may flow into the fresh air volute 4 through the first fresh air inlet 41 .

[0091] The first fresh air inlet 41 may be disposed at the bottom or rear side of the fresh air volute 4 .

[0092] In some embodiments, the fresh air volute 4 may include a first fresh air outlet 42 , which may be connected to the indoor space, and the air flowing into the fresh air volute 4 may be output to the indoor space through the first fresh air outlet 42 .

[0093] In some embodiments, the indoor unit of the air conditioner may include a fresh air fan, which is disposed in the fresh air volute 4 and can drive outdoor air to flow indoors. The fresh air fan is used to introduce outdoor fresh air into the fresh air volute 4 through the first fresh air inlet 41 and output it through the first fresh air outlet 42.

[0094] In some embodiments, the indoor unit of the air conditioner may include a flow guide 43 , which is connected to the fresh air volute 4 , and the outdoor air flowing out of the fresh air volute 4 may flow into the room through the flow guide 43 .

[0095] In some embodiments, the indoor unit of the air conditioner may include a water receiving tray 5 , which is disposed at the bottom of the flow guide 43 . The water receiving tray 5 may be used to receive condensed water formed in the flow guide 43 .

[0096] In some embodiments, the guide member 43 may include a second fresh air inlet 431 , the second fresh air inlet 431 is disposed close to the fresh air volute 4 , and the second fresh air inlet 431 is connected to the first fresh air outlet 42 .

[0097] In some embodiments, the guide member 43 may include a second fresh air outlet 432 , which is arranged away from the fresh air volute 4 , and the outdoor fresh air enters the guide member 43 through the first fresh air outlet 42 and the second fresh air inlet 431 , and is output through the second fresh air outlet 432 .

[0098] In some embodiments, the guide member 43 may include a guide cavity 433, and the interior of the guide member 43 is divided into a plurality of guide cavities 433.

[0099] Outdoor fresh air is introduced into the fresh air volute 4 through the first fresh air inlet 41 and output through the first fresh air outlet 42. Outdoor fresh air is introduced into the guide member 43 through the second fresh air inlet 431 and output from the second fresh air outlet 432 through each guide cavity 433.

[0100] In some embodiments, the guide member 43 may include a drain port 434 , which is disposed at the bottom of the guide member 43 and corresponds to the water receiving tray 5 . Condensed water formed in the guide member 43 may flow to the water receiving tray 5 through the drain port 434 .

[0101] In some embodiments, the guide member 43 may include a drainage member 435 , which is disposed on the guide member 43 . The drainage member 435 is located at the air outlet end of the guide cavity 433 , and the drainage member 435 extends obliquely toward the drainage port 434 .

[0102] In some embodiments, the flow guide member 43 includes a plurality of flow guide cavities 433 , and the plurality of flow guide cavities 433 may be respectively provided with corresponding drainage members 435 .

[0103] When the fresh air fan rotates to drive outdoor air into the room, the outdoor air will form condensation on the inner wall of the guide member 43 after encountering the colder guide member 43. The accumulation of condensation will form condensed water. If the condensed water is not discharged in time, the condensed water may be blown into the room with the outdoor fresh air, affecting the user experience.

[0104] The present application guides the condensed water formed in the guide cavity 433 to the drain port 434 through the drain member 435, and the condensed water is discharged to the water receiving tray 5 through the drain port 434, so that the condensed water can be discharged in time to avoid the accumulation of condensed water and the blowing of condensed water into the room, thereby improving the user experience.

[0105] In some embodiments, the drain outlet 434 is located at one end of the drain member 435 close to the second fresh air inlet 431. Since the outdoor fresh air will be output to the second fresh air outlet 432 along the inner wall of the air guide cavity, the wind speed at the inner wall of the air guide cavity away from the second fresh air inlet 431 is faster. The drain outlet 434 is set at the end of the drain member 435 close to the second fresh air inlet 431 to avoid the condensed water being blown into the room due to the faster wind speed at the end of the drain member 435 away from the second fresh air inlet 431, thereby improving the user experience.

[0106] In some embodiments, the drainage member 435 includes a drainage surface 4351, and the drainage surface 4351 is used to drain condensed water. The condensed water formed in the diversion cavity 433 flows to the drain port 434 through the drainage surface 4351, and the angle between the plane where the drainage surface 4351 is located and the horizontal plane is the first angle a1, a1 is greater than or equal to the first parameter value, and the first parameter value can be any value between 0.5°-15°. The first parameter can be 0.5°, that is, a1≥0.5°, which can prevent the first angle from being too small, and can make the condensed water in the diversion cavity 433 have a tendency to be diverted to the drain port 434, so as to facilitate the discharge of the condensed water in the diversion cavity 433, so as not to cause the condensed water to accumulate in the diversion cavity 433, and not to cause the condensed water to be blown into the room with the fresh air.

[0107] In some embodiments, a1 is less than or equal to the second parameter value, and the second parameter value can be any value between 0.5° and 15°. The second parameter value can be 15°, that is, a1≤15°, which can prevent the first angle from being too large, and can fully utilize the space in the height direction of the main body, so that the height dimension of the drainage member 435 is not too large, and the height dimension of the flow guide member 43 is not too large, which can reduce the space occupied by the flow guide member 43 in the housing 3, improve space utilization and save costs.

[0108] In some embodiments, the guide member 43 may include a first guide segment 436 , and the first guide segment 436 extends from a side close to the second fresh air inlet 431 to a side away from the second fresh air inlet 431 .

[0109] In some embodiments, the guide member 43 may include a second guide section 437, the second guide section 437 is connected to one end of the first guide section 436 away from the second fresh air inlet 431, the second guide section 437 extends to one side of the second fresh air outlet 432, and the first guide section 436 and the second guide section 437 divide the interior of the guide member 43 into a plurality of guide cavities 433. Outdoor fresh air is introduced into the fresh air volute 4 through the first fresh air inlet 41, and is output to the second fresh air inlet 431 through the first fresh air outlet 42. Outdoor fresh air is introduced into the guide member 43 through the second fresh air inlet 431 and is output from the second fresh air outlet 432 through each guide cavity 433.

[0110] In some embodiments, the first guide section 436 and the second guide section 437 divide the interior of the guide member 43 into a plurality of guide chambers 433. The guide chamber 433 plays a role in diverting and guiding the outdoor fresh air flowing out of the fresh air volute 4. The fresh air fan introduces the outdoor fresh air into the guide chamber 433 through the second fresh air inlet 431. Each guide chamber 433 is in a long strip structure. The connection between the first guide section 436 and the second guide section 437 is rounded. The air volume loss in the guide chamber 433 is small. When the air volume is very small, the outdoor fresh air can also be evenly output through the second fresh air outlet 432 to introduce fresh air into the room.

[0111] In some embodiments, the provision of the first guide segment 436 and the second guide segment 437 further enhances the structural strength of the guide member 43 .

[0112] In some embodiments, the guide member 43 includes a plurality of first guide segments 436 and a plurality of second guide segments 437 . A plurality of first guide segments 436 are arranged side by side at intervals, and the plurality of first guide segments 436 are arranged in parallel.

[0113] Outdoor fresh air can pass through each guide cavity 433 to reach the second fresh air outlet 432 corresponding to each guide cavity 433. Each second fresh air outlet 432 evenly outputs the outdoor fresh air to the outdoors. The number of first guide sections 436 can be adaptively adjusted according to the different heights of the guide members 43 and the different air intake volumes.

[0114] The number of the first flow guiding sections 436 and the number of the second flow guiding sections 437 are arranged in a one-to-one correspondence.

[0115] In some embodiments, in order to improve the guiding effect of the guide member 43, the spacing between any two adjacent first guide sections 436 is the same. A certain amount of outdoor fresh air evenly enters the room through each guide cavity 433, and the air volume loss is small, which can ensure that the amount of fresh air introduced from the outside to the room meets the user's use needs, thereby improving the fresh air effect of the air conditioner and improving the user's use comfort.

[0116] In some embodiments, the first guide section 436 is a flat plate structure, so that the fresh air flow in the wind cavity volute flows smoothly, the guide effect is good, and the flat plate structure is easy to process.

[0117] In some embodiments, the length of each first guide segment 436 in the guide member 43 gradually increases from the direction away from the second fresh air outlet 432, that is, the lengths of adjacent first guide segments 436 increase in sequence. The length of the first guide segment 436 closest to the second fresh air outlet 432 is the smallest, the volume of the guide cavity 433 closest to the second fresh air outlet 432 is the smallest, and the amount of fresh air contained is the smallest, so the outdoor fresh air here can be quickly output through the second fresh air outlet 432.

[0118] In some embodiments, the volume of each guide cavity 433 gradually increases from away from the second fresh air outlet 432, and the flow distance of the outdoor fresh air in each guide cavity 433 also gradually increases. The larger guide cavity 433 corresponds to the longer first guide section 436, thereby ensuring that the air output of each guide cavity 433 at the second fresh air outlet 432 is stable and uniform.

[0119] In some embodiments, a plurality of second fresh air outlets 432 are arranged side by side along the length direction of the main body, and the plurality of second fresh air outlets 432 have the same air outlet area, and the plurality of second fresh air outlets 432 are connected to the plurality of guide cavities 433 in a one-to-one correspondence. The plurality of second fresh air outlets 432 have the same length in the length direction of the main body, that is, the plurality of second fresh air outlets 432 have the same shape and size, so as to achieve the same air volume at each fresh air outlet, and the outdoor fresh air is evenly transported from the fresh air volute 4 to the indoor room, thereby improving the comfort of air supply and user experience.

[0120] In some embodiments, a second fresh air outlet 432 can be opened at the front lower part of the guide member 43, so that the outdoor fresh air entering the guide member 43 can flow directly to the second fresh air outlet 432, and the outdoor fresh air can flow directly into the room through the second fresh air outlet 432. The outdoor fresh air flows smoothly into the room, which can ensure the smoothness of the air conditioner introducing outdoor fresh air.

[0121] In some embodiments, the connection between the first guide section 436 and the second guide section 437 is rounded, and the rounded connection increases the guide volume of the guide cavity 433, which is beneficial to the flow of fresh air. The fresh air can smoothly pass through the connection between the first guide section 436 and the second guide section 437 and flow into the second fresh air outlet 432, thereby reducing the loss of outdoor fresh air at the corner of the guide cavity 433, ensuring that the flow rate of the outdoor fresh air in the guide cavity 433 is uniform, and reducing the generation of vortices in the guide cavity 433.

[0122] In some embodiments, the first guide segment 436 and the second guide segment 437 are integrally formed, and the connection between the first guide segment 436 and the second guide segment 437 is rounded, which not only saves production steps and simplifies the production process, but also facilitates manufacturing and demolding through the rounded corner connection, and the guide member 43 has a higher structural strength.

[0123] In some embodiments, the size of each second guide segment 437 in the guide member 43 in the height direction of the main body gradually increases from the direction away from the second fresh air inlet 431 .

[0124] In some embodiments, the length direction of each second guide segment 437 in the guide member 43 is the same as the height direction of the main body.

[0125] In some embodiments, the angle between the length direction of each second guide segment 437 in the guide member 43 and the height direction of the main body is an acute angle.

[0126] In some embodiments, multiple second fresh air outlets 432 are respectively arranged corresponding to multiple guide cavities 433, and the outlet end of at least one guide cavity 433 is correspondingly provided with a drainage piece 435, and the outlet end of at least one guide cavity 433 is correspondingly provided with a drainage port 434.

[0127] In some embodiments, at least one drainage member 435 is provided with a drainage port 434 on one side close to the second fresh air inlet 431. Since the outdoor fresh air will be output to the second fresh air outlet 432 along the inner wall of the air guide cavity, the wind speed at the inner wall of the air guide cavity away from the second fresh air inlet 431 is faster. The drainage port 434 is provided at one end of the drainage member 435 close to the second fresh air inlet 431 to avoid the end of the drainage member 435 away from the second fresh air inlet 431 having a faster wind speed and blowing condensed water into the room, thereby improving the user experience.

[0128] In some embodiments, the guide member 43 may also include a baffle 438, which is connected to one end of at least one first guide section 436 close to the second fresh air inlet 431. The angle between the plane where the baffle 438 is located and the horizontal plane is a second angle a2, a2 ​​is greater than or equal to a third parameter, and the third parameter can be any value between 30°-120°, that is, a2≥30°, which can prevent the second angle from being too small, prevent the baffle 438 from being too parallel, and prevent the shielding area of ​​the baffle 438 and the outdoor fresh air blown into the guide member 43 from being too small, so that the wind inlet resistance in some guide cavities 433 can be increased, and the wind speed of the air output from the second fresh air outlet 432 of the guide cavity can be reduced, so that the wind speed output from each guide cavity 433 is more uniform.

[0129] In some embodiments, a2 is less than or equal to the fourth parameter, and the fourth parameter can be any value between 30°-120°, that is, a2≤120°, so that the second angle will not be too large, the baffle 438 will not be too parallel, and the shielding area of ​​the baffle 438 and the outdoor fresh air blown into the guide member 43 will not be too small, so that the wind inlet resistance in some guide cavities 433 can be increased, and the wind speed of the air output from the second fresh air outlet 432 of the guide cavity can be reduced, so that the wind speed output from each guide cavity 433 is more uniform.

[0130] In some embodiments, the first end of the baffle 438 is connected to one end of the first guide section 436 close to the second fresh air inlet 431, and the second end of the baffle 438 extends toward the second fresh air outlet 432. There is a gap between the second end of the baffle 438 and the adjacent first guide section 436. The length of the gap is defined as a, and the spacing between adjacent first guide sections 436 is defined as b. a / b is greater than or equal to the fifth parameter, and the fifth parameter can be any value between 1 / 6 and 1 / 3, that is, a / b ≥ 1 / 6, so that the gap a will not be too small, and the baffle 438 will not block too large an area of ​​the outdoor fresh air blown into the guide cavity 433. The air inlet resistance in part of the guide cavity 433 can be adjusted to avoid the baffle 438 blocking the wind speed of the air flowing into the guide cavity too much, so that the wind speed output from each guide cavity 433 is more uniform.

[0131] In some embodiments, a / b is greater than or equal to the sixth parameter, and the sixth parameter can be any value between 1 / 6 and 1 / 3, that is, a / b≤1 / 3, so that the gap a will not be too large, and the baffle 438 will not block too small an area of ​​outdoor fresh air blown into the guide cavity 433. The wind inlet resistance in part of the guide cavity 433 can be adjusted to prevent the baffle 438 from being too small and unable to reduce the wind speed of the air flowing into the guide cavity. The wind outlet speed in each guide cavity 433 can be adjusted by setting the baffle 438, so that the wind speed output by each guide cavity 433 is more uniform.
