[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] In the description of the present invention, "a plurality" means more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Reference Figure 1 As shown, the air-conditioning indoor unit of an embodiment of the present invention can be the indoor unit of a wall-mounted air conditioner, the indoor unit of a floor-standing air conditioner or an integrated air-conditioning unit, etc. The present invention will be specifically introduced below taking the indoor unit of a wall-mounted air conditioner as an example.

[0038] Reference Figure 1As shown, an air conditioner indoor unit according to an embodiment of the present invention includes a casing and a chassis 100. The chassis 100 is mounted on a wall, and the casing cover is arranged on the chassis 100, and forms an installation space with the chassis 100. The air conditioner indoor unit according to the embodiment of the present invention also includes a heat exchanger and a fan 200. The heat exchanger is mounted on the chassis 100, and the casing is provided with an air inlet above or in front of the heat exchanger, and the fan 200 is arranged in the air duct of the installation space. Under the action of the fan 200, a negative pressure is formed in the air duct, driving the air of the indoor environment to enter the installation space from the air inlet, and pass through the heat exchanger for heat exchange, and the air after heat exchange is blown out to the indoor environment again through the air duct. After the air in the indoor environment is circulated, the temperature, humidity and other parameters of the indoor environment are adjusted.

[0039] It is understandable that when the air conditioner indoor unit is in cooling mode, the heat exchanger is an evaporator, and a large amount of condensed water will be generated during operation. Therefore, the chassis 100 is provided with a first water tank 110 and a second water tank 120 for receiving the condensed water from the heat exchanger. The first water tank 110 is located below the side of the heat exchanger close to the top, and is used to collect the condensed water flowing down from the side of the heat exchanger close to the top. The second water tank 120 is located below the side of the heat exchanger away from the top, and is used to collect the condensed water flowing down from the side of the heat exchanger away from the top. Since the wall-mounted air conditioner indoor unit has a long strip-shaped air outlet, the heat exchanger is also designed to be long in shape accordingly. In order to facilitate the collection of condensed water, the first water tank 110 is arranged along the Figure 1 The second water tank 120 extends in the left-right direction as shown. Figure 1 Extends in the left-right direction as shown.

[0040] In order to quickly drain the condensed water out of the air conditioner indoor unit, refer to Figure 2 , Figure 3 and Figure 4As shown, the first water tank 110 is configured to be tilted downward from the left and right sides to the middle, and the second water tank 120 is configured to be tilted downward from the left and right sides to the middle. It can be understood that the first water tank 110 includes a bottom wall, a left side wall and a right side wall located on both sides of the left and right directions, and a front side wall and a rear side wall located in the front and rear directions, and multiple wall surfaces form a water storage cavity. The bottom wall can be a plane, a curved surface, a V-shaped surface, etc., which are not specifically limited here. The bottom wall is tilted downward from the left and right sides to the middle, presenting a structure with a low middle and high sides, so that the condensed water dripping from the heat exchanger to the first water tank 110 can flow smoothly from the left and right sides of the first water tank 110 to the middle of the first water tank 110, shortening the drainage distance of the condensed water on the first water tank 110, improving the drainage efficiency, and avoiding the situation that the condensed water freezes and accumulates during the flow due to the long drainage distance of the air conditioner indoor unit in the prior art; and effectively avoiding the phenomenon of trapped water on the left and right sides of the first water tank 110, avoiding bacterial growth. The structure of the second water tank 120 is similar to that of the first water tank 110, and can be understood by referring to the above structural description of the first water tank 110, so that the condensed water dripping from the heat exchanger to the second water tank 120 can flow smoothly from the left and right sides of the second water tank 120 to the middle of the second water tank 120, thereby shortening the drainage distance of the condensed water in the second water tank 120 and improving the drainage efficiency.

[0041] Reference Figure 2 As shown, it can be understood that the chassis 100 is also provided with a guide channel 130, and the guide channel 130 is used to connect the first water tank 110 and the second water tank 120. In order to ensure the smoothness of the drainage of condensed water, the two ends of the guide channel 130 are respectively connected to the middle of the first water tank 110 and the middle of the second water tank 120, so that the condensed water collected by the first water tank 110 and the condensed water collected by the second water tank 120 are gathered in the guide channel 130, so as to be uniformly discharged outside the air conditioner indoor unit. It should be noted that the guide channel 130 can be a tank body or a pipe body, which is selected according to the structural requirements of the air conditioner indoor unit and is not limited here.

[0042] Reference Figure 2 and Figure 4As shown, the air conditioner indoor unit further includes a drainage channel 300, which is used to discharge condensed water outside the air conditioner indoor unit. The drainage channel 300 is fixedly connected to the chassis 100, and the drainage channel 300 is provided with a drainage hole 311, which can be communicated with the middle of the second water tank 120, or communicated with the guide channel 130, and the condensed water gathered in the middle of the second water tank 120 and the lower end of the guide channel 130 can flow out through the drainage hole 311 of the drainage channel 300. It can be understood that in order to achieve the communication between the drainage hole 311 and the guide channel 130, the drainage hole 311 can be provided at the connection between the guide channel 130 and the second water tank 120, can also be provided at the lowest point of the guide channel 130, and can also be provided in the middle of the second water tank 120.

[0043] In the embodiment of the present invention, the first water tank 110 and the second water tank 120 of the chassis 100 for receiving condensed water are arranged to be inclined downward from the left and right sides to the middle, and the chassis 100 is also provided with a guide channel 130 connecting the middle of the first water tank 110 and the middle of the second water tank 120, so that the condensed water in the first water tank 110 and the second water tank 120 can be quickly collected in the middle of the second water tank 120 or the guide channel 130, and a drainage channel 300 is provided to connect the middle of the second water tank 120 or the guide channel 130 through a drainage hole 311, and the drainage channel 300 discharges the condensed water from the air conditioner indoor unit, thereby shortening the drainage distance of the condensed water in the first water tank 110 and the second water tank 120, and improving the drainage efficiency of the condensed water.

[0044] Since the air conditioner indoor unit in the prior art uses left or right drainage, in order to ensure smooth drainage, the air conditioner indoor unit needs to be installed tilted toward the drainage side, and the rolling force generated by the tilt angle must be greater than the surface tension of water. When the tilt angle is too small, drainage will be difficult, and condensed water will overflow, causing the wall to become damp and moldy; when the tilt angle is too large, the actual water storage height of the water tank will be less than the designed water storage height, reducing the water storage capacity of the water tank. The embodiment of the present invention adopts a design that shortens the drainage stroke by half compared to the prior art, so that the air conditioner indoor unit does not need to be installed tilted during installation, reducing the difficulty of installation. Moreover, because the drainage stroke is short, the tilt angles of the first water tank 110 and the second water tank 120 can be designed to be larger, so that the rolling force is greater than the surface tension of the condensed water, and the condensed water can be quickly discharged from the body to prevent condensation of the chassis 100.

[0045] Since there is no need for inclined installation, the water storage capacity of the water storage chambers of the first water tank 110 and the second water tank 120 can be ensured, the dirt holding capacity of the first water tank 110 and the second water tank 120 is increased, the risk of condensation water overflowing from the first water tank 110 and the second water tank 120 is effectively avoided, and the cleanliness of the first water tank 110 and the second water tank 120 is improved, thereby reducing the cleaning frequency of the first water tank 110 and the second water tank 120.

[0046] Reference Figure 4 As shown, it can be understood that the angle between the bottom wall 122 of the second water tank 120 and the horizontal plane is φ, and φ satisfies: 0°<φ≤5°. When the above parameter range is met, the second water tank 120 has a better effect of draining from the left and right sides to the middle. When the angle φ is too large, the water storage capacity of the water storage chamber of the second water tank 120 decreases, and there is a risk of condensed water overflowing; if the above problem is overcome by increasing the side wall of the second water tank 120, there is a problem of increased overall size. It can be understood that the angle between the bottom wall of the first water tank 110 and the horizontal plane is greater than 0° and less than or equal to 5°. When the above parameter range is met, the first water tank 110 has a better effect of draining from the left and right sides to the middle. When the angle is too large, the water storage capacity of the water storage chamber of the first water tank 110 decreases, and there is a risk of condensed water overflowing.

[0047] Reference Figure 2 , Figure 3 and Figure 4 As shown, it can be understood that the chassis 100 includes a volute 140, and the volute 140 includes a first shell portion 141, a second shell portion 142 and a first connecting portion 143, and the two ends of the first connecting portion 143 are respectively connected to the first shell portion 141 and the second shell portion 142. The first shell portion 141 and the second shell portion 142 can be set to a structure with the same size, or a structure with different sizes, so as to meet different air outlet needs. The first shell portion 141 and the second shell portion 142 are respectively engaged with a part of the structure of the casing to form an air duct, and the two air ducts can discharge air synchronously or independently.

[0048] In the embodiment of the present invention, the flow guide channel 130 is a connecting groove 131 formed on the first connecting portion 143, and the two ends of the connecting groove 131 are connected to the first water tank 110 and the second water tank 120. For example, a first notch 111 is provided on the side wall of the middle of the first water tank 110 facing the connecting groove 131, and a second notch 121 is provided on the side wall of the middle of the second water tank 120 facing the connecting groove 131. The condensed water in the first water tank 110 can flow into the connecting groove 131 through the first notch 111, and the condensed water in the second water tank 120 can flow into the connecting groove 131 through the second notch 121, or the connecting groove 131 can collect the condensed water in the first water tank 110 into the middle of the second water tank 120 through the second notch 121. The connecting groove 131 has a simple structure and a good flow guide effect. The connecting groove 131 can include a plurality of groove sections, each of which has a different structure, so as to adapt to the structure of the chassis 100. For example, the groove section of the connecting groove 131 close to the first water groove 110 is a groove section with a larger slope, so that the condensed water of the first water groove 110 can be quickly introduced into the connecting groove 131 to avoid overflowing into the first shell 141 and the second shell 142, causing the wind wheel to blow out the condensed water.

[0049] Reference Figure 3 and Figure 6 As shown, it can be understood that the bottom wall of the connecting groove 131 is provided with a first inclined surface 1311 connected to the bottom wall 122 of the second water tank 120, and the drainage hole 311 is provided on the first inclined surface 1311. The first inclined surface 1311 can be arranged vertically or nearly vertically with the bottom wall 122 of the second water tank 120, so as to facilitate the condensed water of the second water tank 120 to flow into the drainage hole 311 and be discharged through the drainage channel 300. It can be understood that the bottom wall of the connecting groove 131 is also provided with a second inclined surface 1312 connected to the first inclined surface 1311, and the second inclined surface 1312 is located at one end of the first inclined surface 1311 away from the bottom wall 122 of the second water tank 120, and the inclination of the second inclined surface 1312 is less than the inclination of the first inclined surface 1311. The condensed water of the first water tank 110 is guided downward to the connection between the second water tank 120 and the connecting groove 131 through the relatively gentle second inclined surface 1312, which is conducive to the smoothness of the drainage hole 311.

[0050] Reference Figure 6 As shown, it can be understood that the drainage channel 300 is a pipe joint 310, and the pipe joint 310 is integrally formed with the chassis 100, such as integral injection molding. The pipe joint 310 can also be sealed and connected to the chassis 100 by threaded connection or the like. A drainage pipe 320 is provided at one end of the pipe joint 310 away from the drainage hole 311. The drainage pipe 320 is arranged in the space between the volute 140 and the installation wall, which is more convenient to install and easy to adjust the slope relative to the horizontal plane, which is conducive to the smoothness of drainage.

[0051] Reference Figure 5 and Figure 6 As shown, it can be understood that the drain pipe 320 is detachably connected to the pipe joint 310, so the drain pipe 320 can be conveniently installed on the left side of the chassis 100 ( Figure 5 The dotted line in the figure) or the right side ( Figure 5 The drain pipe 320 can extend the condensed water from the middle of the chassis 100 to the left side of the chassis 100 or the right side of the chassis 100, so as to facilitate rapid adjustment according to the installation environment of the air conditioner indoor unit and improve the convenience of installation.

[0052] It is understandable that, when installed in a shaking environment such as a ship or a car, or in a country or region that requires drainage on both sides, the air conditioner indoor unit of the prior art needs to be installed with two drain pipes 320, and the pipe running space needs to be increased, which affects the size of the whole unit. However, the drain pipe 320 of the air conditioner indoor unit of the embodiment of the present invention is connected from the middle of the chassis 100, and the length of the drain pipe 320 can be shortened whether it is discharged to the left or the right. In a shaking environment and an environment that requires drainage on both sides, one drain pipe 320 can be reduced, and the pipe running space can be simultaneously reduced, thereby reducing the size of the whole unit.

[0053] Reference Figure 5 and Figure 6 As shown, it can be understood that the side wall of the volute 140 away from the first water tank 110 is provided with a third water tank 150, and the third water tank 150 is provided on the back side of the volute 140, and is used to collect condensed water generated on the back side of the volute 140. The third water tank 150 extends in the left-right direction, and is arranged downwardly from the left and right sides of the third water tank 150 to the middle of the third water tank 150, presenting a structure with a low middle and high left and right sides, so as to realize the collection and diversion of condensed water, and quickly divert it to the middle of the third water tank 150. The side wall of the first connecting part 143 is provided with a through hole 1431 for connecting the third water tank 150 and the connecting groove 131, and the through hole 1431 can divert the condensed water of the third water tank 150 into the connecting groove 131, and discharge it through the drainage channel 300. The embodiment of the present invention adopts the structure of the third water tank 150, replacing the original solution of attaching thermal insulation cotton, reducing the assembly steps and improving the assembly efficiency. Moreover, the structure of the connecting groove 131 is fully utilized to achieve orderly collection and diversion of condensed water.

[0054] Reference Figure 1 and Figure 2 As shown, the fan 200 of the indoor unit of the air conditioner in the embodiment of the present invention includes a first wind wheel 210 and a second wind wheel 220, and the first wind wheel 210 and the second wind wheel 220 are independent of each other. The first wind wheel 210 is arranged in the first shell 141, and the second wind wheel 220 is arranged in the second shell 142. The first wind wheel 210 and the second wind wheel 220 can be controlled separately, that is, controlled separately, so as to output different air volumes. The first wind wheel 210 and the second wind wheel 220 of this embodiment are both cross-flow wind wheels. Figure 2 and Figure 3 As shown, a first motor seat 1411 is provided on one side of the first shell 141 along the left-right direction, and a first bearing seat 1412 is provided on the other side of the first shell 141 along the left-right direction. A second motor seat 1421 is provided on one side of the second shell 142 along the left-right direction, and a second bearing seat 1422 is provided on the other side of the second shell 142 along the left-right direction.

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the fan 200 also includes a first motor 230 and a second motor 240. The first motor 230 is connected to the first wind wheel 210 and drives the first wind wheel 210 to rotate. The first motor 230 is installed on the first motor seat 1411, and the first bearing seat 1412 is installed with a bearing connected to the first wind wheel 210, so that the operation of the first wind wheel 210 is more stable. The second motor 240 is connected to the first wind wheel 210 and drives the second wind wheel 220 to rotate. The second motor 240 is installed on the second motor seat 1421, and the second bearing seat 1422 is installed with a bearing connected to the second wind wheel 220, so that the operation of the second wind wheel 220 is more stable.

[0056] It can be understood that the first bearing seat 1412 and the second bearing seat 1422 are both arranged on the side facing the first connecting portion 143, so that the influence of condensed water in the connecting groove on the first motor 230 and the second motor 240 can be avoided, thereby reducing the failure rate of the first motor 230 and the second motor 240.

[0057] Reference Figure 1 As shown, it can be understood that the middle part of the first water tank 110 is located between the first shell 141 and the second shell 142, which can further reduce the condensed water of the first water tank 110 entering the air duct in the first shell 141 and the air duct in the second shell 142, avoiding the first wind wheel 210 and the second wind wheel 220 from blowing out condensed water, thereby improving the user experience.

[0058] Similarly, the middle part of the second water tank 120 is located between the first shell 141 and the second shell 142, which can further reduce the condensed water of the second water tank 120 from entering the air duct in the first shell 141 and the air duct in the second shell 142, avoiding the first wind wheel 210 and the second wind wheel 220 from blowing out the condensed water, thereby improving the user experience.
