[0012] Optionally, the water-blocking member is arranged along the water-diverting direction of the water-diverting channel, and the first end of the water-blocking member is connected to the inner wall surface of the water-diverting channel opposite to the volute, and the second end of the water-blocking member extends toward the opening of the water-diverting channel to isolate the water-diverting channel to form an isolation space and a water-diverting space.

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1-5 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a heat exchanger 6, a volute 1, a water inlet trough 11, and a water baffle 3.

[0025] The water inlet trough 11 is used to collect the condensate from the heat exchanger 6, and a portion of the wall of the water inlet trough 11 is formed by a portion of the volute 1. A water baffle 3 is provided at the water inlet trough 11, and an isolation space 113 is formed between the water baffle 3 and the volute 1 to prevent the condensate in the water inlet trough 11 from contacting the volute 1.

[0026] Condensation on the heat exchanger 6 of the air conditioner 100 falls into the water inlet 11. Direct contact between the volute 1 and the condensation causes a drop in temperature, leading to condensation on the air duct side of the volute 1, specifically on the inner surface 13 (the side adjacent to the impeller 7). As the condensation forms droplets, these droplets are blown out by the impeller 7, creating a water spray phenomenon. This water spray can contaminate indoor items and the environment, negatively impacting the user experience.

[0027] According to the present invention, the air conditioner 100 provides a water-blocking component 3 at the water inlet trough 11 to block condensation, thereby forming an isolation space 113 between the water-blocking component 3 and the volute 1 to prevent condensation in the water inlet trough 11 from contacting the volute 1, so as to prevent condensation from occurring on the air duct side of the volute 1, thereby preventing water blowing phenomenon.

[0028] Therefore, the air conditioner 100 according to the present utility model has advantages such as not producing condensation, not producing water blowing phenomenon, and improving user experience.

[0029] like Figures 1-5 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a heat exchanger 6, a volute 1, a fan 7, a water inlet 2, a water inlet trough 11, and a water baffle 3.

[0030] At least a portion of the impeller 7 is disposed within the volute 1. The inner surface 13 of the volute 1 is the surface of the volute 1 adjacent to the impeller 7, that is, the inner surface 13 of the volute 1 is part of the wall of the air duct of the air conditioner 100.

[0031] The first end of the water inlet 2 is connected to the volute 1, and the connection point between the first end of the water inlet 2 and the volute 1 is close to or formed in the water inlet trough 11. The second end of the water inlet 2 is adjacent to the heat exchanger 6 so that the condensate from the heat exchanger 6 received by the second end of the water inlet 2 is led into the water inlet trough 11. Optionally, the water inlet 2 and the volute 1 enclose the water inlet trough 11. Specifically, the water inlet 2 is located on the outer surface 14 of the volute 1.

[0032] like Figures 1-3 As shown, the water inlet 2 is located behind the impeller 7, and the water inlet trough 11 is also located behind the impeller 7. The heat exchanger 6 includes a rear heat exchanger section 61, the lower part 611 of which is located above the bottom wall surface 111 of the water inlet trough 11. The lower part 611 of the rear heat exchanger section 61 is directly opposite the water inlet trough 11 in the vertical direction, so that condensate (condensate water) on the rear heat exchanger section 61 falls into the water inlet trough 11. The vertical direction is as follows... Figure 1 and Figure 5 As shown by arrow A in the diagram.

[0033] Optionally, the volute 1, the water-blocking component 3, and the water-guiding component 2 are formed as a single unit. This reduces the manufacturing difficulty and cost of these components.

[0034] like Figures 1-3 As shown, the water-blocking component 3 is disposed within the water-inlet channel 11 to divide the water-inlet channel 11 into an isolation space 113 and a water-inlet space 112. The isolation space 113 is located between the volute 1 and the water-inlet space 112. Condensate from the heat exchanger 6 can flow into the water-inlet space 112. The isolation space 113 is located between the volute 1 and the water-inlet space 112, that is, between the water-blocking component 3 and the volute 1. The isolation space 113 can prevent the condensate in the water-inlet space 112 (water-inlet channel 11) from contacting the volute 1.

[0035] Optionally, the water-blocking component 3 is provided on the bottom wall surface 111 of the water inlet trough 11. Thus, the water-blocking component 3 can more effectively block the condensate in the water inlet trough 11, thereby further preventing the condensate in the water inlet trough 11 from contacting the volute 1, so as to further prevent condensation from occurring on the air duct side (inner side surface 13) of the volute 1, thereby further preventing the occurrence of water blowing phenomenon.

[0036] like Figures 1-3 As shown, the water-blocking member 3 is arranged along the water-guiding direction of the water-guiding channel 11. One end of the water-blocking member 3 is connected to the bottom wall surface 111 of the water-guiding channel 11. The water-blocking member 3 extends from the connected bottom wall surface 111 to the opening of the water-guiding channel 11 to isolate the water-guiding channel 11, forming an isolation space 113 and a water-guiding space 112. This allows the water-blocking member 3 to more effectively block the condensate in the water-guiding channel 11 (water-guiding space 112), thereby further preventing the condensate in the water-guiding channel 11 from contacting the volute 1.

[0037] Optionally, the first end 33 of the water-blocking member 3 is connected to the bottom wall surface 111 of the water-guiding channel 11, and the second end 34 of the water-blocking member 3 extends upward. The second end 34 of the water-blocking member 3 can extend upward at an angle relative to the bottom wall surface 111, or the second end 34 of the water-blocking member 3 can extend upward vertically relative to the bottom wall surface 111.

[0038] like Figures 1-3 As shown, the height direction of the water-blocking component 3 is perpendicular to the bottom wall surface 111 of the water-inlet channel 11, that is, the water-blocking component 3 is vertically disposed on the bottom wall surface 111 of the water-inlet channel 11. This allows the water-blocking component 3 to more effectively block the condensate in the water-inlet channel 11, thereby further preventing the condensate in the water-inlet channel 11 from contacting the volute 1.

[0039] Optionally, the water-blocking member 3 is arranged along the water-guiding direction of the water-guiding channel 11. The first end 33 of the water-blocking member 3 is in contact with the inner wall surface 114 of the water-guiding channel 11 opposite to the volute 1, and the second end 34 of the water-blocking member 3 extends towards the opening of the water-guiding channel 11 to isolate the water-guiding channel 11, forming an isolation space 113 and a water-guiding space 112. This allows the water-blocking member 3 to more effectively block condensation in the water-guiding channel 11 (water-guiding space 112), thereby further preventing condensation in the water-guiding channel 11 from contacting the volute 1. Optionally, the water-blocking member 3 can be projected onto the cross-section of the water-guiding channel 11 in a straight line, L-shape, or arc shape.

[0040] like Figures 1-3 As shown, a water inlet groove 11 is formed between the first part 12 of the volute 1 and the water inlet member 2. For example, a water inlet groove 11 is formed between at least a portion of the volute throat of the volute 1 and the water inlet member 2. The water-blocking member 3 is parallel to the first part 12 of the volute 1. This allows the water-blocking member 3 to more effectively block condensation in the water inlet groove 11, further preventing the first part 12 of the volute 1 from cooling down due to contact with condensation and thus preventing condensation from forming.

[0041] Optionally, the height H of the water baffle 3 is greater than or equal to 18 mm and less than or equal to 26 mm. Thus, the water baffle 3 can not only more effectively block the condensate in the water inlet trough 11 to further prevent condensation from occurring on the air duct side (inner side 13) of the volute 1, but also prevent the water baffle 3 from obstructing the airflow to the heat exchanger 6, so that the air intake of the heat exchanger 6 is not affected by the water baffle 3.

[0042] In other words, when the height H of the water baffle 3 is greater than 26 mm, the water baffle 3 will affect the air intake of the heat exchanger 6, and thus affect the cooling and heating performance of the air conditioner 100. When the height H of the water baffle 3 is less than 18 mm, the condensate in the water inlet trough 11 is prone to overflowing through the water baffle 3, which will cause the condensate to come into direct contact with the volute 1 (volute throat), resulting in condensation on the air duct side (inner side 13) of the volute 1.

[0043] Alternatively, the height H of the water baffle 3 is greater than or equal to 21 mm and less than or equal to 24 mm. Thus, the water baffle 3 can not only more effectively block the condensate in the water inlet trough 11 to further prevent condensation from forming on the air duct side (inner side 13) of the volute 1, but also further prevent the water baffle 3 from obstructing the airflow to the heat exchanger 6, so that the airflow to the heat exchanger 6 is not affected by the water baffle 3.

[0044] Optionally, the thickness of the water-blocking member 3 is greater than or equal to 1 mm and less than or equal to 4 mm. This allows the water-blocking member 3 to have good structural strength. More preferably, the thickness of the water-blocking member 3 is greater than or equal to 1.5 mm and less than or equal to 2.5 mm. This also allows the water-blocking member 3 to have good structural strength.

[0045] Optionally, the water-blocking component 3 is disposed on the water-introducing component 2, and the difference between the thickness of the water-blocking component 3 and the thickness of the water-introducing component 2 is less than or equal to a preset value. That is, the thickness of the water-blocking component 3 is close to the thickness of the water-introducing component 2 in order to prevent injection molding defects. Further optionally, the thickness of the water-blocking component 3 is approximately equal to the thickness of the water-introducing component 2 in order to further prevent injection molding defects.

[0046] Optionally, the minimum distance between the water-blocking member 3 and the first part 12 in the width direction of the water-inlet channel 11 is greater than or equal to 3 mm and less than or equal to 9 mm. That is, the water-blocking member 3 and the first part 12 are spaced apart in the width direction of the water-inlet channel 11, forming an isolation space 113 between them. This further prevents condensed water in the water-inlet channel 11 from directly contacting the first part 12 (volute 1), thereby further preventing condensation from forming on the air duct side (inner surface 13) of the volute 1. The width direction of the water-inlet channel 11 is as follows... Figure 2 As shown by arrow B.

[0047] Furthermore, by ensuring that the minimum distance between the water-blocking member 3 and the first part 12 in the width direction of the water-inlet channel 11 is greater than or equal to 3 mm and less than or equal to 9 mm, it is possible not only to prevent the gap (isolation space 113) between the water-blocking member 3 and the first part 12 from being too large, which would result in the water-inlet channel 11 having too little space to hold condensate, thus causing the water-inlet channel 11 to have too little water storage capacity, but also to prevent the temperature of the first part 12 (volute 1) from decreasing due to the distance between the water-blocking member 3 and the first part 12 being too small, which would result in condensation on the air duct side of the volute 1.

[0048] In other words, when the minimum distance between the water-blocking component 3 and the first part 12 in the width direction of the water-inlet channel 11 is greater than 9 mm, the gap (isolation space 113) between the water-blocking component 3 and the first part 12 will be too large, resulting in too little space in the water-inlet channel 11 for condensing water. When the minimum distance between the water-blocking component 3 and the first part 12 in the width direction of the water-inlet channel 11 is less than 3 mm, the temperature of the first part 12 (volute 1) will decrease, resulting in condensation on the air duct side of the volute 1.

[0049] Alternatively, the minimum distance between the water-blocking member 3 and the first part 12 in the width direction of the water-inlet channel 11 is greater than or equal to 5 mm and less than or equal to 7 mm. This not only further prevents the gap (isolation space 113) between the water-blocking member 3 and the first part 12 from being too large, which would result in the water-inlet channel 11 having too little space to hold condensate, i.e., the water storage capacity of the water-inlet channel 11 being too small, but also further prevents the temperature of the first part 12 (volute 1) from decreasing due to the distance between the water-blocking member 3 and the first part 12 being too small, which would result in condensation on the air duct side of the volute 1.

[0050] like Figures 1-3 As shown, the water inlet trough 11 includes a first water inlet trough 115 and a second water inlet trough 116. The first water inlet trough 115 is adjacent to the volute tongue 15 of the volute 1, and the second water inlet trough 116 is located on the side of the volute 1 opposite to the volute tongue 15. A water-blocking element 3 is provided at least one of the first water inlet trough 115 and the second water inlet trough 116. This further prevents condensed water in the water inlet trough 11 from contacting the volute 1, thereby further preventing condensation from forming on the air duct side (inner surface 13) of the volute 1.

[0051] like Figure 4 and Figure 5 As shown, the air conditioner 100 also includes a water guide 4 for guiding condensate in the water inlet trough 11. The water inlet space of the water inlet trough 11 includes a first water outlet 31 and a second water outlet 32, and the water guide 4 is provided on at least one of the first water outlet 31 and the second water outlet 32. By providing the water guide 4 on at least one of the first water outlet 31 and the second water outlet 32, the condensate in the water inlet trough 11 can be guided by the water guide 4, so that the condensate can be discharged from the water inlet trough 11 more smoothly, and further prevent the condensate from accumulating in the water inlet trough 11.

[0052] Optionally, the water-blocking member 3 extends along the length of the water-inlet channel 11. For example, the water-blocking member 3 extends along the length of the air conditioner 100. The length direction of the water-inlet channel 11 is as follows: Figure 4 and Figure 5As indicated by arrow C, the water-blocking component 3 is inclined along the length of the water-inlet channel 11 so that the first water outlet 31 is located below the second water outlet 32. This facilitates the flow of condensate in the water-inlet channel 11 along the water-blocking component 3, thereby allowing the condensate to be discharged from the water-inlet channel 11 more smoothly and preventing condensate from accumulating in the water-inlet channel 11.

[0053] like Figure 4 and Figure 5 As shown, the water guide 4 has a water guiding surface, at least a portion of which is an inclined surface 41. This allows the condensed water in the water inlet trough 11 to flow more smoothly downwards along the inclined surface 41, thus enabling the condensed water to drain more smoothly from the water inlet trough 11 and further preventing the condensed water from accumulating in the water inlet trough 11.

[0054] Optionally, the upper edge 411 of the inclined surface 41 is connected to the first water outlet 31, the inclined surface 41 extends downward from the first water outlet 31 of the water baffle 3, and the inclined surface 41 extends from the first water outlet 31 of the water baffle 3 along the length of the water channel 11 in a direction away from the second water outlet 32.

[0055] For example, the length direction of the water-blocking member 3 is consistent with the left-right direction, that is, the water-blocking member 3 extends along the left-right direction. The first water outlet 31 is on the left side of the water-blocking member 3, and the second water outlet 32 ​​is on the right side of the water-blocking member 3. The inclined surface 41 extends downward and to the left from the first water outlet 31 of the water-blocking member 3. The left-right direction is as follows. Figure 4 and Figure 5 As shown by arrow D in the diagram.

[0056] Optionally, the angle (inclination angle) β1 between the inclined plane 41 and the horizontal plane is greater than or equal to 30 degrees and less than or equal to 70 degrees. As a result, the condensed water in the water inlet trough 11 can flow more smoothly down the inclined plane 41, thereby allowing the condensed water to be discharged from the water inlet trough 11 more smoothly and further preventing the condensed water from accumulating in the water inlet trough 11.

[0057] Alternatively, the angle β1 between the inclined plane 41 and the horizontal plane is greater than or equal to 45 degrees and less than or equal to 55 degrees. This allows the condensate in the water inlet trough 11 to flow more smoothly down the inclined plane 41, thereby allowing the condensate to be discharged from the water inlet trough 11 more smoothly and further preventing the condensate from accumulating in the water inlet trough 11.

[0058] like Figure 4 and Figure 5 As shown, the water guiding surface includes a first arc surface 42, a second arc surface 43 and an inclined surface 41. The first arc surface 42 is connected to the water-blocking member 3, and the inclined surface 41 is connected between the first arc surface 42 and the second arc surface 43.

[0059] By providing a first arc surface 42 between the water-blocking component 3 and the inclined surface 41, condensate near the water-blocking component 3 (e.g., condensate near the first water outlet 31) can flow more smoothly to the inclined surface 41, preventing condensate from getting stuck between the water-blocking component 3 and the inclined surface 41. By providing a second arc surface 43, the angle between the flow direction of the condensate and the vertical direction can be reduced, allowing the condensate to fall better into the component below the water guide 4 used to collect the condensate, thus preventing condensate leakage.

[0060] Optionally, the upper edge of the first arc surface 42 is connected to the first water outlet 31 of the water-blocking member 3, and the lower edge of the first arc surface 42 is connected to the upper edge 411 of the inclined surface 41. The upper edge of the second arc surface 43 is connected to the lower edge 412 of the inclined surface 41. The condensed water on the inclined surface 41 will flow onto the second arc surface 43 and then flow along the second arc surface 43.

[0061] like Figure 5 As shown, the first side 421 and the second side 422 of the first arc surface 42 define the first inclined plane S1, and the first side 431 and the second side 432 of the second arc surface 43 define the second inclined plane S2. The inclination angle β1 of the inclined plane 41 is greater than the inclination angle β2 of the first inclined plane S1 and less than the inclination angle β3 of the second inclined plane S2. That is to say,

[0062] This not only allows the condensed water in the water inlet trough 11 to flow more smoothly downwards along the water guide surface of the water guide 4, but also allows the condensed water to fall better into the component below the water guide 4 for receiving the condensed water, so as to prevent the condensed water from spilling.

[0063] Optionally, the upper and lower edges of the first arc surface 42 are located on the first inclined surface S1, and the upper and lower edges of the second arc surface 43 are located on the second inclined surface S2.

[0064] Optionally, the inclination angle β2 of the first inclined surface S1 is greater than or equal to 15 degrees and less than or equal to 35 degrees. As a result, the first arc surface 42 can more smoothly guide the condensate to the inclined surface 41, thereby further preventing the condensate from getting stuck between the water-blocking component 3 and the inclined surface 41, and further preventing the condensate from accumulating in the water-guiding trough 11.

[0065] Alternatively, the inclination angle β2 of the first inclined surface S1 is greater than or equal to 23 degrees and less than or equal to 29 degrees. As a result, the first arc surface 42 can more smoothly guide the condensate to the inclined surface 41, thereby further preventing the condensate from getting stuck between the water-blocking component 3 and the inclined surface 41, and further preventing the condensate from accumulating in the water-guiding trough 11.

[0066] Optionally, the inclination angle β3 of the second inclined plane S2 is greater than or equal to 60 degrees and less than or equal to 85 degrees. This allows the condensate to fall more effectively into the component below the water guide 4 used to collect the condensate, thereby further preventing condensate leakage.

[0067] Alternatively, the inclination angle β3 of the second inclined plane S2 is greater than or equal to 70 degrees and less than or equal to 75 degrees. This allows the condensate to fall more effectively into the component below the water guide 4 that collects the condensate, thereby further preventing condensate leakage.

[0068] Optionally, the lower edge of the second arc surface 43 (the lower end of the water guide 4) is located directly below the drainage channel so that the condensate flowing downward along the second arc surface 43 falls into the drainage channel.
