[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0029] In the utility model, unless otherwise stated, the orientation words such as 'up, down, top, bottom' are generally for the direction shown in the drawings, or for the vertical, perpendicular or gravity direction of the components themselves. Similarly, for the convenience of understanding and description, 'inner and outer' refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the utility model.

[0030] Obviously, the above-described embodiments are only a part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the utility model.

[0031] In order to solve the problem that the air conditioner is easy to leak in the prior art, the utility model provides a kind of inner unit bottom shell structure, air conditioner indoor unit and air conditioner.

[0032] As shown in Figures 1 to 5 Illustration, inner unit bottom shell structure includes air duct baffle 10, water channel baffle 20 and support piece 30, water channel baffle 20 is located on the side of air duct baffle 10 away from impeller 60 and is located on the upper portion of air duct baffle 10, the bottom of water channel baffle 20 is bent towards air duct baffle 10 and is connected with air duct baffle 10, to form water channel 90, both ends of support piece 30 are connected with the top of air duct baffle 10 and the top of water channel baffle 20 respectively.

[0033] By setting the inner machine bottom shell structure to include the air duct baffle 10, the water duct baffle 20 and the support 30, the water duct baffle 20 is located on the side of the air duct baffle 10 away from the impeller 60 and on the upper part of the air duct baffle 10, the bottom of the water duct baffle 20 is bent towards the air duct baffle 10 and connected with the air duct baffle 10 to form the water duct 90, and the two ends of the support 30 are connected with the top of the air duct baffle 10 and the top of the water duct baffle 20 respectively, so that the air duct baffle 10 and the water duct baffle 20 are connected as a whole by setting the support 30 above the water duct 90, thereby limiting the bending deformation of the air duct baffle 10 to the rear, preventing the air duct baffle 10 from being contacted when the bending deformation is too large, avoiding the condensed water on the evaporator 70 from flowing out along the inner wall of the air duct to cause water leakage, and greatly improving the user experience.

[0034] In the embodiment, the support 30 is in a strip-shaped plate structure, and further, the width of the support 30 is 6mm to 8mm. Such width design not only ensures the structural strength of the support 30, but also does not occupy too much space above the water duct 90, so that most of the water droplets condensed by the evaporator 70 above can directly fall into the water duct 90, thereby avoiding the condensed water formed by the evaporator 70 from entering the air duct 80 to cause water leakage.

[0035] In the embodiment, the support 30 is a plurality of supports, and the plurality of supports 30 are arranged at intervals along the width direction of the air duct baffle 10. It can be understood that the width direction of the air duct baffle 10 is the up-down direction in the air duct baffle 10 and the water duct baffle 20. Figure 4 Figure 5

[0036] Further, since the easily deformed position of the air duct baffle 10 is the middle position of the air duct baffle 10, at least one support 30 is located at the middle position of the air duct baffle 10, thereby improving the anti-deformation ability of the air duct baffle 10. In the embodiment, at least two supports 30 are located at the middle position of the air duct baffle 10.

[0037] In the embodiment, the support 30 can be integrally injection molded with the air duct baffle 10 and the water duct baffle 20, thereby improving the structural strength.

[0038] In the embodiment, the support 30 has a preset distance between the connection position of the support 30 and the top end of the air duct baffle 10. It can be understood that the top of the air duct baffle 10 is the position of the upper part of the air duct baffle 10, and the support 30 is not connected with the top end of the air duct baffle 10, but is connected at a lower position of the top end of the air duct baffle 10. Through the above setting, the part of the air duct baffle 10 above the support 30 can play a blocking role, and most of the water droplets condensed by the evaporator 70 above will directly fall into the water duct 90, and a part of the water droplets falling on the support 30 will be blocked by the air duct baffle 10, thereby avoiding the condensed water formed by the evaporator 70 from entering the air duct 80 to cause water leakage.​​

[0039] Specifically, in the embodiment, the preset distance is 3mm to 5mm. Through the above setting, while ensuring that the top end of the air duct baffle 10 has the function of stopping water droplets, the connection between the support 30 and the air duct baffle 10 is located as much as possible in the upper part of the air duct baffle 10, thereby improving the support and limiting effect of the support 30 on the air duct baffle 10, and limiting the bending deformation of the air duct baffle 10 backward.

[0040] As shown in Figure 3 , the top end of the air duct baffle 10 has a top end face 11 and a side face 12 connected in sequence. The top end face 11 and the side face 12 are both inclined downward away from the impeller 60. That is, the top end face 11 and the side face 12 are sequentially inclined toward the water channel 90. Through the above setting, the accumulation of condensed water at the top end of the air duct baffle 10 can be reduced, and under the action of gravity, the condensed water accumulated at the top end of the air duct baffle 10 flows into the water channel 90 along the top end face 11 and the side face 12, avoiding flowing forward to the air duct 80 to cause water leakage.

[0041] In addition, by setting the side face 12 as an inclined face, the width of the top end of the air duct baffle 10 can be reduced, and the accumulation of condensed water at the top end of the air duct baffle 10 can also be reduced. Specifically, in the embodiment, the width of the top end of the air duct baffle 10 is 0.8mm to 1mm.

[0042] In the embodiment, the angle α between the top end face 11 and the horizontal direction is 3° to 5°. That is, the top end of the air duct baffle 10 is slightly inclined backward from the horizontal.

[0043] In the embodiment, the angle β between the side face 12 and the horizontal direction is 28° to 45°.

[0044] As shown in Figures 2 to 3 , the support 30 has a bending section 31 forming a limiting gap for limiting and stopping the evaporator 70. Specifically, the support 30 includes a first section, a second section and a third section connected in sequence, wherein the first section is connected with the water channel baffle 20, the third section is connected with the air duct baffle 10, and the second section is the bending section 31. The bending section 31 is parallel to the inner side of the evaporator 70, and the height thereof is not less than 2mm, so that the bending section 31 is substantially perpendicular to the first section, thereby forming a limiting gap matched with the evaporator 70. When the air duct baffle 10 deforms backward, the bending section 31 abuts against the inner side of the evaporator 70, thereby avoiding further deformation of the air duct baffle 10.

[0045] For the existing air conditioner, the internal temperature is not uniform during refrigeration, and there is a temperature difference in different areas. When the surface temperature of the part is lower than the dew point temperature of the air flowing through, condensation will form on the cold surface. In the cold areas near the water channel, such as the top of the air duct baffle, the two sides of the air duct, etc., condensation water accumulation phenomenon is easy to appear, and when the water accumulation is more, it is easy to flow into the air duct, causing water leakage.

[0046] As shown in Figures 4 to 5 , the inner machine bottom shell structure further includes a baffle 40 located on both sides of the air duct baffle 10. The peripheral side wall 41 of the baffle 40 is inclined outward in a direction away from the air duct baffle 10. Specifically, the baffle 40 is an arc-shaped structure, which includes a peripheral side wall 41 and a radial wall. The peripheral side wall 41 is arc-shaped, and the outer circumference of the peripheral side wall 41 is connected with the radial wall, and the inner circumference is connected with the air duct baffle 10. As can be seen from Figure 5 , the peripheral side wall 41 is inclined to the left and right sides of the air duct baffle 10, that is, the baffle 40 is a trapezoidal circular table structure.

[0047] As shown in Figures 4 to 5 , the inner machine bottom shell structure further includes a water retaining rib 50 arranged at the connection between the baffle 40 and the air duct baffle 10. Specifically, the water retaining rib 50 is arranged at the connection between the peripheral side wall 41 and the air duct baffle 10. It can be understood that the water retaining rib 50 is also arc-shaped and protrudes from the connection between the peripheral side wall 41 and the air duct baffle 10. In this embodiment, the width of the water retaining rib 50 is 1mm to 1.2mm, and the height is greater than or equal to 1.5mm. Through the above arrangement, the baffle 40 forms a water storage structure, effectively preventing the outflow of a small amount of condensate water generated in the baffle 40, and avoiding the condensate water from easily flowing into the air duct 80 to cause water leakage.

[0048] Further, the top surface of the water retaining rib 50 is an inclined surface inclined outward in a direction away from the air duct baffle 10. Through the above arrangement, the water retaining rib 50 can better play a water retaining role, preventing the condensate water at the baffle 40 from flowing into the air duct 80 to cause water leakage.

[0049] The application also provides an air conditioner indoor unit comprising the above-mentioned inner machine bottom shell structure.

[0050] The application also provides an air conditioner comprising the above-mentioned air conditioner indoor unit.

[0051] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects: through setting the indoor unit bottom shell structure includes air duct baffle 10, water channel baffle 20 and support 30, water channel baffle 20 is located at the side of air duct baffle 10 away from impeller 60 and is located at the upper portion of air duct baffle 10, the bottom of water channel baffle 20 is bent towards air duct baffle 10 and is connected with air duct baffle 10 to form water channel 90, both ends of support 30 are connected with the top of air duct baffle 10 and the top of water channel baffle 20 respectively, so that by setting support 30 above water channel 90, air duct baffle 10 and water channel baffle 20 are connected as a whole, thereby limiting air duct baffle 10 to bend and deform backwards, preventing air duct baffle 10 from bending and deforming too much to contact evaporator 70, avoiding the condensed water on evaporator 70 from flowing out along the inner wall of air duct to cause water leakage, greatly improving user experience.
