DETAILED DESCRIPTION

[0058] 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.

[0059] Hereinafter, an air conditioner according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0060] Reference Figure 1-Figure 4 The air conditioner according to the embodiment of the present invention comprises: a casing 10, a heat exchanger assembly 20 and an air duct assembly 30. The casing 10 comprises a chassis 14 and a shell 1. The chassis 14 is arranged on the bottom surface of the shell 1. The shell 1 is formed with an air inlet 120 and an air outlet 110. A water collecting tank 141 and a positioning structure 142 are formed on the chassis 14. The positioning structure 142 is used to position the shell 1. The chassis 14 can support the shell 1. The positioning structure 142 on the chassis 14 can position the shell 1, and the stability of the shell 1 can be enhanced.

[0061] The positioning structure 142 is located on the outer peripheral side of the water collecting tank 141, and a first water guiding structure 145 is formed between the positioning structure 142 and the water collecting tank 141. The first water guiding structure 145 is used to guide the water at the positioning structure 142 into the water collecting tank 141. When there is water on the shell 1, the water can flow along the shell 1 to the positioning structure 142 on the chassis 14 under the action of its own gravity. The water at the positioning structure 142 is guided into the water collecting tank 141 by the first water guiding structure 145. The water at the positioning structure 142 can be gathered in the water collecting tank 141. This can prevent the water at the positioning structure 142 from overflowing onto the floor, thus avoiding water accumulation and making the floor slippery. In addition, the positioning structure 142 is located on the outer peripheral side of the water collecting tank 141, which makes it more convenient to guide the water at the positioning structure 142 into the water collecting tank 141. The flow direction of water at the positioning structure 142 can be referred to Figure 3 Direction indicated by the arrow.

[0062] For example, when the air conditioner is cooling, the temperature of the air in the casing 10 is low, and condensed water is easily generated on the outer surface of the casing 10. The condensed water can flow downward along the casing 1 under the action of its own gravity. Since the lower end of the casing 1 cooperates with the positioning structure 142 on the chassis 14, the condensed water can flow to the positioning structure 142 on the chassis 14 and gather at the positioning structure 142. The condensed water gathered at the positioning structure 142 is guided to the water collecting tank 141 through the first water guiding structure 145. The water at the positioning structure 142 can be gathered in the water collecting tank 141, which can prevent the water at the positioning structure 142 from overflowing onto the floor, thereby preventing the floor from being wet and slippery.

[0063] Reference Figure 2 and Figure 7 The heat exchanger assembly 20 is disposed in the casing 10 , the air duct assembly 30 is disposed in the casing 10 , and a second water guide structure 53 is formed on the air duct assembly 30 , and the second water guide structure 53 is used to guide the water on the air duct assembly 30 into the water collecting tank 141 .

[0064] When the air conditioner is working, the air in the housing 10 exchanges heat with the heat exchanger assembly 20, and the air duct assembly 30 is prone to produce condensed water in an alternating hot and cold environment. The water on the air duct assembly 30 can be drained by guiding the water on the air duct assembly 30 to the water collecting tank 141 through the second water guide structure 53. The water on the air duct assembly 30 can be collected in the water collecting tank 141. This can prevent the water on the air duct assembly 30 from dripping onto other parts of the air conditioner and affecting the normal operation of the air conditioner, avoid affecting the service life of other parts, and ensure that the air conditioner can work normally. The flow direction of water on the air duct assembly 30 can refer to Figure 8 Direction indicated by the arrow.

[0065] For example, when an electric control component or a wiring harness for connecting the electric control component is provided below the air duct assembly 30, condensed water on the air duct assembly 30 is likely to drip onto the electric control component or the wiring harness, which may easily cause a safety hazard. Therefore, by guiding the water on the air duct assembly 30 to the water collecting tank 141 through the second water guiding structure 53, safety hazards can be avoided and the air conditioner can be ensured to work normally.

[0066] Therefore, by guiding the water at the positioning structure 142 into the water collecting tank 141 through the first water guiding structure 145, the water at the positioning structure 142 can be prevented from overflowing onto the floor, thereby avoiding water accumulation on the floor; by guiding the water on the air duct assembly 30 into the water collecting tank 141 through the second water guiding structure 53, the water on the air duct assembly 30 (such as condensed water) can be prevented from dripping onto other components of the air conditioner, thereby avoiding affecting the service life of other components and ensuring the normal operation of the air conditioner.

[0067] Reference Figure 1 and Figure 2The air conditioner may be a split floor-standing air conditioner, and the air conditioner may include an air conditioner indoor unit 100 and an air conditioner outdoor unit. For example, the air conditioner indoor unit 100 may be a cabinet unit, and the air conditioner indoor unit 100 may include a housing 10, a heat exchanger assembly 20, and an air duct assembly 30. The housing 10 may include the above-mentioned chassis 14 and a shell 1, and an air inlet 120 and an air outlet 110 are formed on the shell 1, and an air inlet grille 121 is provided at the air outlet 110; the air inlet 120 and the air outlet 110 may both be connected to the room to facilitate air circulation. The housing 10 may also include a top cover 13, and the top cover 13 is provided on the top of the shell 1, the heat exchanger assembly 20, and the air duct assembly 30. The heat exchanger assembly 20 is located at the front side of the air inlet 120, and the air duct assembly 30 is located between the heat exchanger assembly 20 and the air outlet 110, and the air outlet 110 may be connected to the room. Among them, the heat exchanger assembly 20 may include a heat exchanger 21, a heat exchanger bracket 22 and an electric auxiliary heating component 23, and the heat exchanger 21 and the electric auxiliary heating component 23 may be arranged on the heat exchanger bracket 22; the air duct assembly 30 may include an air duct volute 31 and a wind wheel 32, and the wind wheel 32 is arranged in the air duct volute 31, and the wind wheel 32 can drive the airflow in the air duct volute 31 into the air outlet channel 5a in the air outlet frame 50.

[0068] When the air conditioner is working, air can enter the casing 10 from the air inlet 120, the air entering the casing 10 can exchange heat with the heat exchanger assembly 20, and the air after heat exchange can be blown into the room from the air outlet 110 through the air duct assembly 30, thereby adjusting the temperature of the indoor space.

[0069] According to the air conditioner of the embodiment of the present invention, water on the shell 1 (for example, condensed water) can flow to the positioning structure 142 on the chassis 14, and the water at the positioning structure 142 can be guided to the water collecting tank 141 through the first water guiding structure 145, so that the water at the positioning structure 142 can be prevented from overflowing onto the floor, thereby avoiding water accumulation on the floor; the water on the air duct assembly 30 can be guided to the water collecting tank 141 through the second water guiding structure 53, so that the water on the air duct assembly 30 (for example, condensed water) can be prevented from dripping onto other components of the air conditioner, thereby ensuring the normal operation of the air conditioner.

[0070] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the first water guide structure 145 includes a guide groove 146, which runs through the inner wall of the water collecting trough 141. The guide groove 146 can be connected with the water collecting trough 141, so as to facilitate the drainage of water at the positioning structure 142 into the water collecting trough 141, so that the water at the positioning structure 142 can be collected in the water collecting trough 141.

[0071] Reference Figure 6According to some optional embodiments of the present invention, the bottom wall of the guide groove 146 is formed as a guide bottom wall 147, and the guide bottom wall 147 extends downward at an angle in the direction from the positioning structure 142 to the water collecting tank 141. This has a better water drainage effect and is more convenient for drainage. It can speed up the flow of water in the guide groove 146, and can more quickly guide the water at the positioning structure 142 to the water collecting tank 141, which can effectively prevent the water at the positioning structure 142 from overflowing onto the floor, thereby preventing water from accumulating on the floor.

[0072] Continue to refer to Figure 6 In some optional embodiments of the present invention, the angle α between the diversion bottom wall 147 and the horizontal plane ranges from 3 to 30°. For example, the angle α between the diversion bottom wall 147 and the horizontal plane can be 7°, 10°, 13°, 17° or 25°. The angle α between the diversion bottom wall 147 and the horizontal plane has a suitable range, so that the diversion bottom wall 147 is inclined downward at a suitable angle in the direction from the positioning structure 142 to the water collection trough 141, which can facilitate drainage, ensure the guiding effect of the diversion trough 146 on the water at the positioning structure 142, and can quickly drain to prevent the water at the positioning structure 142 from overflowing onto the floor and avoid water accumulation on the floor.

[0073] Reference Figure 3 According to some optional embodiments of the present invention, the positioning structure 142 is arranged along the circumference of the water collecting tank 141. When the shell 1 is positioned by the positioning structure 142, the shell 1 can be positioned along the circumference of the water collecting tank 141, which can further improve the stability of the shell 1. There are multiple guide grooves 146, and the multiple guide grooves 146 are arranged at intervals along the circumference of the water collecting tank 141, which can more quickly divert water at the positioning structure 142 into the water collecting tank 141, and prevent the water at the positioning structure 142 from overflowing onto the floor.

[0074] Reference Figure 3 According to some optional embodiments of the present invention, the positioning structure 142 includes a matching groove 143, the matching groove 143 extends along the circumference of the water collecting groove 141, and at least part of the lower end of the shell 1 is accommodated in the matching groove 143. For example, the lower end of the shell 1 is accommodated in the matching groove 143; or, the lower end of a part of the structure of the shell 1 is accommodated in the matching groove 143, and the water on the shell 1 can flow into the matching groove 143 along the shell 1. A guide groove 146 is formed between the matching groove 143 and the water collecting groove 141, and the guide groove 146 connects the matching groove 143 and the water collecting groove 141. The water in the matching groove 143 can flow into the water collecting groove 141 through the guide groove 146, so as to prevent the water in the matching groove 143 from overflowing onto the floor, thereby preventing water from accumulating on the floor.

[0075] Reference Figure 2In some optional embodiments of the present invention, the housing 1 includes a rear housing 12 and a front panel 11, the front panel 11 is arranged at the front side of the rear housing 12, the air inlet 120 is formed at the rear housing 12, the air outlet 110 is formed at the front panel 11, the heat exchanger assembly 20 is arranged at the rear side of the air duct assembly 30, and the lower end of the rear housing 12 is accommodated in the matching groove 143. Since the rear housing 12 is closer to the heat exchanger assembly 20 than the front panel 11, condensed water is more likely to be generated on the rear housing 12 when the air conditioner is cooling. With the lower end of the rear housing 12 accommodated in the matching groove 143, the condensed water on the rear housing 12 can flow into the matching groove 143, and the condensed water in the matching groove 143 can flow into the water collecting groove 141 under the guidance of the guide groove 146 between the matching groove 143 and the water collecting groove 141, so as to avoid excessive water in the matching groove 143 from overflowing onto the floor, thereby avoiding water accumulation on the floor.

[0076] Reference Figure 3 According to some optional embodiments of the present invention, the positioning structure 142 includes a plurality of positioning grooves 144, and the plurality of positioning grooves 144 are arranged at intervals along the circumference of the shell 1. The lower end of the shell 1 has a positioning protrusion, and the positioning protrusion is engaged with the positioning groove 144, so that the shell 1 can be engaged with the chassis 14, which can improve the installation stability of the shell 1.

[0077] A guide groove 146 is formed between the positioning groove 144 and the water collecting groove 141, and the guide groove 146 connects the positioning groove 144 and the water collecting groove 141. The positioning protrusion is engaged with the positioning groove 144, and the water on the housing 1 can flow into the positioning groove 144 along the housing 1 and the positioning protrusion, and the positioning groove 144 and the water collecting groove 141 are connected through the guide groove 146. The water in the positioning groove 144 can flow into the water collecting groove 141 along the guide groove 146 to prevent excessive water accumulation in the positioning groove 144 and overflow onto the floor.

The positioning protrusion is suitable for being inserted into the positioning groove 144 to install the front panel 11 on the chassis 14. The condensed water on the front panel 11 can flow downward along the front panel 11 into the positioning groove 144, and the guide groove 146 connected to the positioning groove 144 can drain the water in the positioning groove 144 into the water collecting groove 141. A positioning protrusion is also formed at the lower end of the rear shell 12, and a positioning groove 144 is formed on the chassis 14 to cooperate with the positioning protrusion of the rear shell 12.

[0079] Reference Figure 2 , Figure 8 and Fig.15 According to some embodiments of the present invention, the air duct assembly 30 includes an air duct component 3 and an air outlet frame component 5, the air outlet frame component 5 is located between the air duct component 3 and the air outlet 110, the air outlet frame component 5 includes an air outlet frame 50, an air outlet channel 5a is formed in the air outlet frame 50, the air outlet channel 5a can be connected to the air outlet 110, and a second water guide structure 53 is formed on the air outlet frame 50, the second water guide structure 53 includes at least one group of water guide ribs 54, and the second water guide structure 53 includes at least one drainage hole 55.

[0080] The second water-guiding structure 53 includes at least one group of water-guiding ribs 54 and at least one drainage hole 55, including the following situations: the second water-guiding structure 53 may include one group of water-guiding ribs 54 and one drainage hole 55; or, the second water-guiding structure 53 may also include multiple groups of water-guiding ribs 54 and multiple drainage holes 55; or, the second water-guiding structure 53 may also include one group of water-guiding ribs 54 and multiple drainage holes 55; or, the second water-guiding structure 53 may also include multiple groups of water-guiding ribs 54 and one drainage hole 55.

[0081] For example, in a specific embodiment of the present invention, the second water guiding structure 53 includes two groups of water guiding ribs 54 and two drainage holes 55 .

[0082] A water guiding rib group 54 is formed on the outer wall of the air outlet frame 50, and a drainage hole 55 is formed at the bottom of the air outlet frame 50. The water guiding rib group 54 is used to guide water on the outer wall of the air outlet frame 50 to the lower end of the air outlet frame 50 and downwardly discharge it into the water collecting tank 141 through the drainage hole 55.

[0083] When the air conditioner is cooling, the air flow entering the casing 10 can exchange heat with the heat exchanger assembly 20. Since the air flow after heat exchange will flow through the air outlet channel 5a, the temperature in the air outlet channel 5a is relatively low, so that a temperature difference will be generated inside and outside the air outlet channel 5a, resulting in condensed water on the outer wall of the air outlet channel 5a.

[0084] The water guide rib group 54 can guide the condensed water on the outer wall of the air outlet frame 50 to flow, facilitate the drainage of the air outlet frame 50, prevent the condensed water on the outer wall of the air outlet frame 50 from dripping onto other components of the air conditioner, avoid affecting the service life of other components, and better ensure the normal operation of the air conditioner. In addition, compared with sticking a sponge on the outer wall of the air outlet frame 50, the water on the outer wall of the air outlet frame 50 is drained to the lower end of the air outlet frame 50 and discharged into the water collection tank 141 through the water guide rib group 54 on the outer wall of the air outlet frame 50, which can save costs and reduce assembly time.

[0085] Reference Fig.12 and Fig.16 According to some optional embodiments of the present invention, the water guide rib group 54 includes a plurality of water guide ribs 541, the plurality of water guide ribs 541 are arranged in sequence along the up-down direction, two adjacent water guide ribs 541 are cross-arranged and spaced apart, an angle is formed between the water guide ribs 541 and the vertical direction, and an angle is formed between the water guide ribs 541 and the horizontal direction. Water on the outer wall of the air outlet frame 50 can flow along the length direction of the water guide ribs 541, and the water guide ribs 541 located on the upper side can divert water to the water guide ribs 541 located on the lower side.

[0086] Thus, the water guide rib 541 can guide the condensed water on the outer wall of the air outlet frame 50 to flow, and can quickly drain the condensed water to the drain hole 55 and discharge it into the water collecting tank 141 through the drain hole 55, so that the condensed water on the outer wall of the air outlet frame 50 can be better drained, and the condensed water can be prevented from dripping onto other parts of the air conditioner, thereby ensuring the normal operation of the air conditioner. There is an angle between the water guide rib 541 and the vertical direction, and there is also an angle between the water guide rib 541 and the horizontal direction, so that the drainage effect of the water guide rib 541 is better, and the condensed water can be drained to the drain hole 55 more quickly.

[0087] For example, the upper surface of the water guiding rib 541 can be a plane, and when the water on the outer wall of the air outlet frame 50 is guided by the water guiding rib 541, the water can flow along the upper surface of the water guiding rib 541; for another example, the upper surface of the water guiding rib 541 can also be concave downward to form a water-guiding groove, so that when the water on the outer wall of the air outlet frame 50 is guided by the water guiding rib 541, the water can flow along the groove. In this way, the water guiding effect of the water guiding rib 541 is better, and water can be prevented from flowing out from the outer edge of the water guiding rib 541 and avoiding flowing onto other structural parts of the air conditioner.

[0088] Reference Fig.16 According to some optional embodiments of the present invention, the outer edge of the upper end surface 526 of the air outlet frame 50 is formed with a first water retaining rib 525, which can prevent the water on the upper end surface 526 of the air outlet frame 50 from flowing out from the outer edge, and prevent water from dripping onto other structural parts of the air conditioner, causing the other structural parts to age and fail. The upper end surface 526 of the air outlet frame 50 is formed with a drainage groove 527, which is used to drain the water on the upper end surface 526 of the air outlet frame 50 to the outer side wall of the air outlet frame 50 with the water guide rib group 54, so as to facilitate the drainage of the upper end surface 526 of the air outlet frame 50, avoid the accumulation of condensed water on the upper end surface 526 of the air outlet frame 50, and also prevent the upper end surface 526 of the air outlet frame 50 from accumulating too much water, causing the accumulated water to overflow onto other parts of the air conditioner, thereby ensuring that the air conditioner can work normally.

[0089] For example, two side walls in the width direction of the drainage groove 527 are formed as drainage walls 528, and the drainage walls 528 extend obliquely from top to bottom toward the direction of the bottom wall adjacent to the drainage groove 527. The drainage walls 528 can drain the condensed water on the upper end surface 526 of the air outlet frame 50 and collect it in the drainage groove 527, thereby draining the water on the upper end surface 526 of the air outlet frame 50 to the outer side wall of the air outlet frame 50 having the water guide rib group 54.

The water retaining convex ring 564 is arranged around the mounting hole 563. When the air conditioner is cooling, condensed water is also easily generated on the air guide assembly, and the condensed water on the air guide assembly can be discharged into the air outlet bottom wall 56 along the air guide assembly. By forming a water retaining convex ring 564 arranged around the mounting hole 563 on the air outlet bottom wall 56, water on the air outlet bottom wall 56 can be prevented from flowing out of the mounting hole 563, so that water can be prevented from flowing onto other structural parts of the air conditioner and causing aging and failure of other structural parts, thereby avoiding affecting the service life of other structural parts, and ensuring that the air conditioner can work normally.

[0094] For example, the driving motor for driving the air guide assembly can be located on the lower side of the air outlet bottom wall 56, and the water retaining ring 564 is arranged around the mounting hole 563 to prevent water on the air outlet bottom wall 56 from flowing from the mounting hole 563 to the driving motor, thereby ensuring that the driving motor can work normally and reducing safety hazards.
