Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

For example, the indoor unit may include a wall-mounted indoor unit installed on a wall of the indoor space.
As shown in fig. 1 to 3, an air conditioner indoor unit 100 according to an embodiment of the present invention includes a casing 1, a plurality of heat exchangers 2, a plurality of air duct assemblies 4, and a plurality of fans 3. The heat exchanger 2 is the indoor heat exchanger, and the fan 3 is the indoor fan.
An air inlet and a plurality of air outlets 11 are formed on the machine case 1, the plurality of air outlets 11 are formed at the bottom of the machine case 1, and the plurality of air outlets 11 include a first air outlet 111 and a second air outlet 112 which are arranged left and right. The plurality of heat exchangers 2 are all arranged in the casing 1, and the plurality of heat exchangers 2 comprise a first heat exchanger 21 and a second heat exchanger 22 which are arranged on the left and right. The plurality of air duct assemblies 4 are all arranged in the machine shell 1, and the plurality of air duct assemblies 4 comprise a first air duct assembly 43 and a second air duct assembly 44. The plurality of fans 3 include a first fan 31 and a second fan 32, the first fan 31 being disposed on the first air duct assembly 43, and the second fan 32 being disposed on the second air duct assembly 44.
For example, in the examples of fig. 2, 4 to 9, the number of the air outlets 11, the air duct assemblies 4, the heat exchangers 2, and the fans 3 is two, the two air outlets 11 are the first air outlet 111 and the second air outlet 112, the two air duct assemblies 4 are the first air duct assembly 43 and the second air duct assembly 44, the two heat exchangers 2 are the first heat exchanger 21 and the second heat exchanger 22, and the two fans 3 are the first fan 31 and the second fan 32. Wherein the first fan 31 and the second fan 32 may be cross-flow fans. When the air conditioner is started, indoor air can flow into the machine shell 1 from the air inlet under the action of the first fan 31 and the second fan 32 and flows through the first heat exchanger 21 and the second heat exchanger 22 for heat exchange, the air after heat exchange can be sucked in along the radial direction of the fan 3 and then conveyed to the first air outlet 111 and the second air outlet 112, and finally flows out of the first air outlet 111 and the second air outlet 112, so that the indoor temperature can be adjusted.
Fig. 2, 4-9 show two air outlets 11, two air duct assemblies 4, two heat exchangers 2 and two fans 3 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solutions of the present application that the solutions can be applied to three or more air outlets 11, air duct assemblies 4, heat exchangers 2 and fans 3, and this also falls within the protection scope of the present invention.
The first air duct assembly 43 has a first air duct 431 communicated with the first air outlet 111, and the second air duct assembly 44 has a second air duct 441 communicated with the second air outlet 112. For example, in the examples of fig. 2, 4-9, when indoor air flows into the cabinet 1 from the air inlet, a part of the air flow passes through the first heat exchanger 21 under the action of the first fan 31 to exchange heat, and the air after heat exchange can enter the first fan 31, then flow to the first air outlet 111 along the first air duct 431, and finally flow into the indoor from the first air outlet 111; another part of the airflow passes through the second heat exchanger 22 under the action of the second fan 32 to exchange heat, and the air after heat exchange can enter the second fan 32, then flow to the second air outlet 112 along the second air duct 441, and finally flow into the room from the second air outlet 112.
From this, through the above setting, first heat exchanger 21 and second heat exchanger 22 can independent control air supply temperature respectively, first fan 31 and second fan 32 can independent control air supply amount respectively, make the temperature and the amount of wind of the air current that blows out from first air outlet 111 and second air outlet 112 can be different, thereby can realize the subregion air supply of air conditioner 100, make same air conditioner 100 can realize different heat transfer effects in different regions, different user's demands in the same room have been satisfied, user's use travelling comfort has effectively been promoted. Moreover, when one of the first outlet 111 and the second outlet 112 is closed, the single-side air supply of the air conditioner indoor unit 100 can be realized according to the user requirement.
The first air outlet 111 and the second air outlet 112 extend obliquely upward from the direction of the end close to each other toward the end far from each other, the extending direction of the first heat exchanger 21 is the same as that of the first air outlet 111, the extending direction of the second heat exchanger 22 is the same as that of the second air outlet 112, the extending direction of the first fan 31 is the same as that of the first air outlet 111, and the extending direction of the second fan 32 is the same as that of the second air outlet 112. For example, in the examples of fig. 2, 3, 6-9, the first and second air duct assemblies 43, 44 are generally V-shaped, the first and second air outlets 111, 112 are generally V-shaped, the first and second heat exchangers 21, 22 are generally V-shaped, and the first and second fans 31, 32 are generally V-shaped.
Therefore, through the arrangement, the distances between the first heat exchanger 21 and the first fan 31, between the second heat exchanger 22 and the second fan 32, between the first fan 31 and the first air outlet 111, and between the second fan 32 and the second air outlet 112 can be more uniform, so that the temperature and the air volume of the air flow output by the first air outlet 111 and the second air outlet 112 can be more uniform, and the user experience can be further improved. Furthermore, the first outlet 111 and the second outlet 112 can guide the air flow, so that the air flow flowing out from the outlet 11 (for example, the first outlet 111) at the left end of the casing 1 can flow into the room obliquely leftwards relative to the cross section passing through the center of the casing 1, and the air flow flowing out from the outlet 11 (for example, the second outlet 112) at the right end of the casing 1 can flow into the room obliquely rightwards relative to the cross section passing through the center of the casing 1, so that the air flow can be diffused towards the left and right sides relative to the cross section passing through the center of the casing 1, the air supply angle of the indoor unit 100 of the air conditioner can be increased, and the air supply range of the indoor unit 100 can be expanded. In addition, when the air outlet temperatures and the air volumes of the first air outlet 111 and the second air outlet 112 are different, the first air outlet 111 and the second air outlet 112 arranged in this way can avoid mutual interference of air flows, so that the air flows with different temperatures flowing out of the first air outlet 111 and the second air outlet 112 can enable different indoor areas to have different temperatures, and the requirements of users in different areas on comfortable air temperatures can be better met.

Therefore, by arranging the first water collecting tank 41, the second water collecting tank 42, the first water outlet 411 and the second water outlet 421, the first water collecting tank 41 can be used for collecting the condensed water flowing down from the surface of the first heat exchanger 21 and discharging the condensed water through the first water outlet 411, and the second water collecting tank 42 can be used for collecting the condensed water flowing down from the surface of the second heat exchanger 22 and discharging the condensed water through the second water outlet 421, so that the condensed water dropping from the first heat exchanger 21 and the second heat exchanger 22 can be prevented from influencing the normal operation of other parts (such as the first fan 31 and the second fan 32) in the cabinet 1, and the water leakage of the indoor unit 100 of the air conditioner can be prevented. Moreover, because the first water outlet 411 and the second water outlet 421 are both located at the lowest position, the water in the first water collecting tank 41 and the second water collecting tank 42 can be completely discharged through the corresponding first water outlet 411 and the corresponding second water outlet 421, so that the water stored in the first water collecting tank 41 and the second water collecting tank 42 is avoided, the normal use of the indoor unit 100 of the air conditioner can be ensured, and the reliability is high.
According to the utility model discloses air conditioner 100, upwards extend through direction, the slope that makes first air outlet 111 and second air outlet 112 from the one end orientation that is close to each other keep away from each other one end, can effectively increase air supply angle, enlarge air conditioner 100's air supply scope. Moreover, by extending the bottom wall of the first water collecting tank 41 and the bottom wall of the second water collecting tank 42 from the end adjacent to each other toward the end away from each other, obliquely upward, and positioning the first water outlet 411 at the lowest position of the first water collecting tank 41 and the second water outlet 421 at the lowest position of the second water collecting tank 42, the condensed water in the first water collecting tank 41 and the second water collecting tank 42 can be completely discharged through the first water outlet 411 and the second water outlet 421, so that the normal use of the air conditioner indoor unit 100 can be effectively ensured, and the long-term reliability of the air conditioner indoor unit 100 can be improved.
In some embodiments of the present invention, referring to fig. 10-12 and 14, the first water collecting tank 41 includes a first subset water tank 412, a second subset water tank 413 and a third subset water tank 414, the first subset water tank 412 is located below the second subset water tank 413, the third subset water tank 414 is connected between the first subset water tank 412 and the second subset water tank 413, the first subset water tank 412 and the second subset water tank 413 are located at two radial sides of the first fan 31, the third subset water tank 414 is located at an end of the first fan 31 far away from the center of the housing 1, and the first water outlet 411 is formed at an end of the first subset water tank 412 far away from the third subset water tank 414.
For example, in the example of fig. 10-12, 14, the first water collection sump 41 is substantially U-shaped. Referring to the arrow direction in fig. 12, when the surface of the first heat exchanger 21 generates the condensed water, since the bottom wall of the first water collection groove 41 extends obliquely upward from the end adjacent to the second water collection groove 42 toward the end away from the second water collection groove 42, the condensed water dropping into the second sub-set water groove 413 flows along the bottom wall of the second sub-set water groove 413 toward the center of the air duct assembly 4. Since the height of the second sub-set water groove 413 is greater than that of the first sub-set water groove 412, the condensed water dropped into the third sub-set water groove 414 may flow into the first sub-set water groove 412, and flow along the bottom wall of the first sub-set water groove 412 toward the center of the air duct assembly 4 together with the condensed water dropped into the first sub-set water groove 412, and finally be discharged through the first water outlet 411.
The second water collecting tank 42 includes a fourth water collecting tank 422, a fifth water collecting tank 423, and a sixth water collecting tank 424, the fourth water collecting tank 422 is located below the fifth water collecting tank 423, the sixth water collecting tank 424 is connected between the fourth water collecting tank 422 and the fifth water collecting tank 423, the fourth water collecting tank 422 and the fifth water collecting tank 423 are located at two radial sides of the second fan 32, the sixth water collecting tank is located at an end of the second fan 32 away from the center of the cabinet 1, and the second water outlet 421 is formed at an end of the fourth water collecting tank 422 away from the sixth water collecting tank 424.
For example, in the examples of fig. 10-12, 14, second water collection trough 42 may be symmetrical to first water collection trough 41 with respect to a cross-section of the center of air duct assembly 4. Referring to the arrow direction in fig. 12, when the surface of the second heat exchanger 22 generates the condensed water, since the bottom wall of the second water collection groove 42 extends obliquely upward from the end adjacent to the first water collection groove 41 toward the end away from the first water collection groove 41, the condensed water dropping into the fifth sub-set water groove 423 flows toward the center of the air duct assembly 4 along the bottom wall of the fifth sub-set water groove 423. Since the height of the fifth sub-set water groove 423 is greater than that of the fourth sub-set water groove 422, the condensed water dropped into the sixth sub-set water groove 424 may flow into the fourth sub-set water groove 422, and flow along the bottom wall of the fourth sub-set water groove 422 toward the center of the air duct assembly 4 together with the condensed water dropped into the fourth sub-set water groove 422, and finally be discharged through the second water outlet 421.

In a further embodiment of the present invention, as shown in fig. 12, the ends of the second and fourth sub-set water tanks 413 and 422 adjacent to each other are respectively formed with a third water outlet 4131. Thus, since the bottom walls of the second sub-set water tank 413 and the fourth sub-set water tank 422 extend obliquely upward from the ends adjacent to each other toward the ends away from each other, the third water outlet 4131 thus provided facilitates the drainage of the condensed water in the second sub-set water tank 413 and the fourth sub-set water tank 422, thereby preventing the generation of water accumulation in the second sub-set water tank 413 and the fourth sub-set water tank 422, and further ensuring the reliability of the air conditioner indoor unit 100.
In some embodiments of the present invention, referring to fig. 14, a protrusion 4121 is disposed between the first sub-set water tank 412 and the fourth sub-set water tank 422, and the height of the protrusion 4121 is gradually reduced in a direction from the protrusion 4121 toward the first sub-set water tank 412 and the fourth sub-set water tank 422. Therefore, by providing the protrusion 4121, the condensed water in the first sub-water collection tank 412 and the fourth sub-water collection tank 422 can be effectively stopped, so as to prevent water from being stored between the first sub-water collection tank 412 and the fourth sub-water collection tank 422, and ensure that the first water outlet 411 and the second water outlet 421 can be located at the lowest positions, so that the condensed water can effectively flow into the first water outlet 411 and the second water outlet 421 located at two sides of the protrusion 4121.

In some optional embodiments of the present invention, referring to fig. 2 and 3, the included angle between the plane of the first air outlet 111 and the cross section passing through the center of the casing 1 is α1The included angle between the plane of the second air outlet 112 and the cross section passing through the center of the casing 1 is α2Wherein α is1、α2Satisfies the following conditions: alpha is not less than 85 DEG1＜90°，85°≤α2< 90 deg. Specifically, for example, when α1Or alpha2When the angle is smaller than 85 °, an included angle between the plane where the first air outlet 111 or the second air outlet 112 is located and the cross section passing through the center of the housing 1 is too small, which may cause an excessively large inclination angle of the first air outlet 111 or the second air outlet 112 relative to the horizontal plane, on one hand, may cause an excessively large occupied space of the whole air conditioner indoor unit 100 and poor appearance aesthetic property; on the other hand, against the heat exchanger 2 and the fan 3 in the casing 1And (4) spatial layout. When alpha is1Or alpha2When the angle is larger than 90 °, the air supply angle of the first air outlet 111 or the second air outlet 112 is reduced, so as to reduce the air supply range of the indoor unit 100 of the air conditioner.
Thereby, by making alpha1、α2Satisfies the following conditions: alpha is not less than 85 DEG1Alpha is less than 90 degrees and less than or equal to 85 degrees2< 90 °, while ensuring that the first air outlet 111 and the second air outlet 112 can effectively enlarge the air supply range of the air conditioner indoor unit 100, the structural design of the air conditioner indoor unit 100 is more reasonable, the structural strength of the air conditioner indoor unit 100 can be improved, the occupied space of the air conditioner indoor unit 100 is reduced, the spatial layout of the heat exchanger 2 and the fan 3 in the casing 1 can be more reasonable, and the appearance attractiveness of the air conditioner indoor unit 100 can be effectively improved. Further optionally, α1、α2Can further satisfy: alpha is alpha1＝87°，α287 deg.. But is not limited thereto.
