Description

Technical Field

[0001] This invention relates to an indoor unit of an air conditioner, and more particularly to an evaporator mounting structure for an indoor unit of an air conditioner. Background Technology

[0002] With the improvement of living standards, air conditioning has become an essential appliance for regulating indoor air temperature, humidity, and air purity in daily life. To regulate kitchen air, air-conditioning-style range hoods were invented, integrating the indoor unit (air conditioner) into the hood. These indoor units include a fan and an evaporator. Air entering the indoor unit flows through the evaporator and is then delivered into the kitchen through the fan's outlet, improving cooking comfort. However, existing air conditioner indoor units lack anti-condensation structures. When the air conditioner is operating, the cooling energy from the evaporator is directly transferred to the surface of the indoor unit, causing condensation and reducing its reliability. Therefore, further improvements to the existing air conditioner indoor unit structure are necessary. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an evaporator installation structure for an air conditioner indoor unit that can effectively prevent condensation, in light of the above-mentioned existing technology.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an evaporator installation structure for an air conditioner indoor unit, including a water receiving pan assembly and an evaporator installed on the water receiving pan assembly, wherein the two sides of the evaporator are liquid collection pipes, characterized in that: a support portion adapted to the liquid collection pipe is formed on the water receiving pan assembly, a support rib is provided on the inner support surface of the support portion, and the pipe wall of the liquid collection pipe contacts the support rib and leaves a gap between it and the inner support surface.

[0005] To effectively support the evaporator, the support ribs are spaced apart along the length of the inner support surface.

[0006] The drip tray assembly can have various structures. Preferably, the drip tray assembly includes a lower drip tray cover and an upper drip tray cover that are assembled together. The support portion includes a lower support portion located on the side of the lower drip tray cover and an upper support portion located on the side of the upper drip tray cover. Correspondingly, the support ribs include a lower support rib located on the inner support surface of the lower support portion and an upper support rib located on the inner support surface of the upper support portion. When the lower drip tray cover and the upper drip tray cover are assembled, the wall of the liquid collecting pipe is in contact with the lower support ribs and the upper support ribs. The separate structure of the lower drip tray cover and the upper drip tray cover in the drip tray assembly facilitates the installation and positioning of the evaporator.

[0007] To provide better support for the evaporator, the upper support portion is provided on both sides of the upper cover of the water receiving tray, and the lower support portion is provided on one side of the lower cover of the water receiving tray. The lower support portion and the upper support portion on the same side are wrapped around the liquid collecting pipe on the same side, and the liquid collecting pipe on the other side is supported on the upper support portion on the corresponding side.

[0008] Further preferably, the liquid collecting pipe is a circular pipe, and correspondingly, the cross-sections of the inner support surface of the lower support part and the inner support surface of the upper support part are both arc-shaped.

[0009] Further preferably, the evaporator is inclined relative to the vertical plane, and correspondingly, the upper support and the lower support are inclined relative to the vertical plane, and the inclination angle is consistent with the inclination angle of the evaporator.

[0010] More preferably, the evaporator is tilted at an angle of 45° to 75° relative to the horizontal plane.

[0011] To ensure proper assembly of the lower and upper covers of the water tray, the corresponding sides of the lower and upper covers are fixedly connected by screws.

[0012] To further prevent condensation from forming on the outer surface of the air conditioner's indoor unit, the drip tray assembly also includes an inner drip tray installed inside the lower cover of the drip tray and providing thermal insulation. The inner drip tray has a supporting surface on which the bottom of the evaporator is supported. Thus, by providing the inner drip tray, the cold air from the evaporator surface is less likely to be transferred to the outer surfaces of the lower and upper covers of the drip tray, preventing condensation.

[0013] Further preferably, the inner water tray is a foam water tray.

[0014] To ensure sufficient clearance between the pipe wall and the inner support surface, the height of the support ribs should be no less than 1 mm. This is essential for effective condensation prevention.

[0015] Compared with the prior art, the advantages of the present invention are as follows: the water collection pan assembly of the air conditioner indoor unit forms a support part adapted to the liquid collection pipe, and the inner support surface of the support part is provided with support ribs. The pipe wall of the evaporator liquid collection pipe contacts the support ribs and leaves a gap between it and the inner support surface. In this way, the line-surface contact between the liquid collection pipe and the support ribs allows the evaporator to be reliably supported and the installation to be more secure. Furthermore, due to the existence of the above-mentioned gap, the cold energy on the liquid collection pipe will not be directly transferred to the outer surface of the water collection pan assembly, preventing condensation and improving the reliability of the air conditioner indoor unit.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 7 As shown, the evaporator mounting structure of the indoor unit of the air conditioner in this embodiment includes a drip tray assembly and an evaporator 1 mounted on the drip tray assembly. The evaporator 1 has two sides with liquid collection pipes 11, which are circular pipes connected to each other by flat pipes 12. The drip tray assembly has a support portion adapted to the liquid collection pipes 11. The support portion has an inner support surface with a circular arc cross-section to support the liquid collection pipes 11.

[0025] In this embodiment, the water tray assembly includes a lower water tray cover 2 and an upper water tray cover 3. The upper water tray cover 3 is detachably mounted on the lower water tray cover 2. The two can be installed by a stop limit and are connected and fixed by screws 4. A lower support portion 21 is provided on one side of the lower water tray cover 2. The lower support portion 21 has an inner support surface 22, and lower support ribs 23 protrude from the inner support surface 22. The lower support ribs 23 are spaced apart along the length direction of the inner support surface 22. Upper support portions 31 are provided on both sides of the upper water tray cover 3. Each upper support portion 31 has an inner support surface 32, and upper support ribs 33 protrude from the inner support surface 32. The upper support ribs 33 are spaced apart along the length direction of the inner support surface 32.

[0026] With the lower cover 2 and upper cover 3 of the water tray assembled, the lower support 21 cooperates with the upper support 31 on the same side and wraps around the outer periphery of the liquid collecting pipe 11 on the same side. At this time, the outer peripheral wall of the liquid collecting pipe 11 on this side is in contact with the lower support rib 23 and the upper support rib 33, and there are gaps between the outer peripheral wall of the liquid collecting pipe 11 and the inner support surface 22 of the lower support and the inner support surface 32 of the upper support. Since the lower cover 2 of the water tray only has a lower support 21 on one side, see [reference needed]. Figure 2 Therefore, the collecting pipe 11 is supported on the upper support portion 31 on the corresponding side, meaning that the outer peripheral wall of the collecting pipe 11 on this side only contacts the upper support rib 33 on the same side. In this embodiment, to ensure the installation gap between the collecting pipe 11 and the lower support portion 21 and the upper support portion 31, the height of both the lower support rib 23 and the upper support rib 33 is not less than 1mm. The existence of this gap prevents the cold energy on the collecting pipe 11 from being directly transferred to the outer surface of the water receiving tray assembly, thereby preventing condensation from occurring on the outer surfaces of the lower cover 2 and the upper cover 3 of the water receiving tray.

[0027] In this embodiment, the evaporator 1 is inclined relative to the vertical plane, such as... Figure 4 As shown, the tilt angle α of the evaporator 1 relative to the horizontal plane is 45° to 75°. Correspondingly, the upper support part 31 and the lower support part 21 are inclined relative to the vertical plane, and the tilt angle is consistent with the tilt angle of the evaporator 1, ensuring that the installation tilt angle of the evaporator 1 is within the required range.

[0028] To address the condensation issue, the water tray assembly in this embodiment further includes an inner water tray 4 that provides thermal insulation. The inner water tray 4 is installed inside the lower cover 2 of the water tray and its shape is adapted to the lower cover 2. Typically, the inner water tray 4 is a foam water tray. In addition, the lower part of the inner water tray 4 in this embodiment has a support surface 41, on which the bottom of the evaporator 1 is supported, making the installation of the evaporator 1 more reliable.
