[0018] The embodiments of the present disclosure are explained in more detail below, and examples of these embodiments are illustrated in the accompanying drawings. The embodiments explained in connection with the accompanying drawings are exemplary, serve only to explain the present disclosure, and cannot be understood as limiting the present disclosure.

[0019] The indoor unit 100 according to the embodiment of the present disclosure comprises an indoor unit body 1, an evaporator 2, and a water conduit assembly 3. An installation cavity 11 is arranged in the indoor unit body 1, the inner wall surface of which comprises a first wall surface 111 and a second wall surface 112. The evaporator 2 is arranged in the installation cavity 11, the evaporator 2 having a first end and a second end, the first end 21 of the evaporator being opposite the first wall surface 111, and the second end 22 of the evaporator being opposite the second wall surface 112. The water conduit assembly comprises a first water conduit rib 31 arranged on the first wall surface 111, the free end of the first water conduit rib 31 resting against the underside of the first end 21 of the evaporator.

[0020] One end of the first water-conducting rib 31 is connected to the first wall surface 111, while the other end of the first water-conducting rib 31, namely the free end, rests against the underside of the first end 21 of the evaporator. This interrupts the flow path of the condensate on the first wall surface 111. Because the first water-conducting rib 31 rests against the underside of the evaporator 2, the condensate on the first wall surface 111 can flow along the direction of extension of the first water-conducting rib 31 to the evaporator 2 and along the evaporator 2 into the water collection tray 7, thus creating a channel for the condensate on the first wall surface 111.

[0021] In contrast to the phenomenon in related technologies, where excessive water absorption by the sponge at the sealing position between the evaporator 2 and the indoor unit body 1 causes the condensate to flow along the inner wall of the indoor unit body 1, in the embodiment of the present disclosure, the first end 21 of the evaporator of the indoor unit 100 is opposite the first wall surface 111 of the indoor unit body 1, wherein a first water-conducting rib 31 is arranged on the first wall surface 111, so that the first water-conducting rib 31 can absorb and conduct the condensate on the first wall surface 111, and by the fact that the free end of the first water-conducting rib 31 rests against the underside of the first end 21 of the evaporator,The condensate guided by the first water guide rib 31 can flow along the extension direction of the first water guide rib 31 to the evaporator and flow down along the evaporator 2 onto the water collection tray 7, in order to prevent the condensate from flowing down the surface of the first wall surface 111 and thus causing leakage from the indoor unit 100, which provides guidance for the condensate on the first wall surface 111 and improves the user experience.

[0022] As in Fig. As shown in Figures 1 to 3, the evaporator 2 has a V-shaped cross-section within a projection plane orthogonal to the longitudinal direction of the indoor unit 100, with the apex of the evaporator 2 pointing downwards. The first end 21 of the evaporator 2 represents the rear end of the evaporator 2, while the second end 22 represents the front end of the evaporator 2. The first wall surface 111 of the installation cavity 11 is located at the rear, and the second wall surface 112 of the installation cavity 11 is located at the front. The rear end of the evaporator 2 is opposite the first wall surface 111 located at the rear, and the front end of the evaporator 2 is opposite the second wall surface 112 located at the front.

[0023] It is understood that during operation of the evaporator 2, since the surface temperature of the evaporator 2 is lower than the dew point temperature of the ambient air, water vapor in the air condenses into water droplets on the surface of the evaporator 2, forming condensate. A water collection tray 7 is typically provided at the bottom of the evaporator 2, and the condensate on the evaporator 2 flows along its surface into the water collection tray 7.

[0024] It should be noted that in the present application, the first end 21 of the evaporator is not limited to the rear end of the evaporator 2, the second end 22 is not limited to the front end of the evaporator 2, the first wall surface 111 of the installation cavity 11 is not limited to the rear, and the second wall surface 112 of the installation cavity 11 is not limited to the front. It is only guaranteed that the first end 21 of the evaporator is opposite the first wall surface 111 of the installation cavity 11 and the second end 22 of the evaporator is opposite the second wall surface 112 of the installation cavity 11.In another embodiment, for example, the first end 21 of the evaporator is the front end of the evaporator 2, the second end 22 is the rear end of the evaporator 2, the first wall surface 111 of the installation cavity 11 is located at the front and the second wall surface 112 of the installation cavity 11 is located at the rear.

[0025] In some embodiments, the projection of the first water conduit rib 31 extends horizontally from the first wall surface 111 to the first end 21 of the evaporator within a projection plane orthogonal to the longitudinal direction of the indoor unit 100;

[0026] In particular, as in Fig. Figure 1 shows a first gap 4 between the first end 21 of the evaporator and the first wall surface 111. The first water-conducting rib 31 is arranged within the first gap 4 and extends along the front-to-back direction. The rear end of the first water-conducting rib 31 is connected to the first wall surface 111, while the front end of the first water-conducting rib 31 rests against the underside of the first end 21 of the evaporator.In the present embodiment, a first water-conducting rib 31 is arranged in a gap between the first end 21 of the evaporator and the first wall surface 111, extending along the front-to-back direction, with the front end of the first water-conducting rib 31 bearing against the underside of the first end 21 of the evaporator, so that the first water-conducting rib 31 can guide the condensate on the first wall surface 111 to the evaporator 2 to carry out heat exchange, thereby improving the guiding effect of the first water-conducting rib 31.

[0027] Furthermore, the front end of the first water conduit rib 31 engages by 0.5 mm-1 mm into the rear end of the evaporator 2 to further guarantee the guiding effect of the first water conduit rib 31.

[0028] In some embodiments, the first end 21 of the evaporator has an upper side surface and a lower side surface, wherein the first water conduit rib 31 is located above the lower side surface of the first end 21 of the evaporator.

[0029] As particularly in Fig. As shown in Figure 2, the upper side surface 211 of the first end of the evaporator is located above the first water-conducting rib 31, while the lower side surface 212 of the first end of the evaporator is located above the first water-conducting rib 31. That is, the first water-conducting rib 31 is arranged between the upper side surface 211 of the first end of the evaporator and the lower side surface 212 of the first end of the evaporator.

[0030] Optionally, the first end 21 of the evaporator has a first sealing surface 213, wherein the upper side surface 211 of the first end of the evaporator, the first sealing surface 213 and the lower side surface 212 of the first end of the evaporator are successively connected, and wherein the front end of the first water conduit rib 31 abuts the first sealing surface 213.

[0031] For example, the first water-conducting rib 31 is located adjacent to the lower side surface 212 of the first end of the evaporator, compared to the upper side surface 211 of the first end of the evaporator. This facilitates the first water-conducting rib 31 from absorbing the condensate from the first wall surface 111, thereby improving the guiding effect for the condensate.

[0032] In some embodiments, the water conduit assembly 3 further comprises a first water-absorbing element 32, wherein the first water-absorbing element 32 is arranged between the first wall surface 111 and the first end 21 of the evaporator and is located above the first water conduit rib 31.

[0033] In particular, as in Fig. 2 shown, the upper end of the first water-absorbing element 32 is located on the first wall surface 111, while the lower end of the first water-absorbing element 32 rests on a part of the first sealing surface 213 of the first end 21 of the evaporator, thereby creating a sealed connection between the evaporator 2 and the first wall surface 111.

[0034] Due to the water-absorbing properties of the first water-absorbing element 32, it absorbs water when it comes into contact with condensation. When the first water-absorbing element 32 becomes saturated, it overflows, and the overflowing portion of condensation flows along the surface of the first wall surface 111. In the present embodiment, the first water-conducting rib 31 is arranged below the first water-absorbing element 32, so that the first water-conducting rib 31 directs the portion of condensation overflowing from the first water-absorbing element 32 to the evaporator 2, thus preventing the condensation from overflowing from the ventilation opening and improving the user experience.

[0035] Furthermore, in the present embodiment, the position of the first water-conducting rib 31 can be limited. This standardizes the arrangement position of the first water-absorbing element 32 and improves the uniformity of its arrangement position.

[0036] Furthermore, the first water-absorbing element 32 is connected to the first end 21 of the evaporator by gluing.

[0037] Furthermore, the first water-absorbing element 32 is a sponge.

[0038] In some embodiments, the water conduit assembly 3 further comprises a second water conduit rib 33, which is arranged on the second wall surface 112, wherein the free end of the second water conduit rib 33 rests at least against the underside of the second end 22 of the evaporator.

[0039] In particular, as in Fig. Figure 3 shows the second end 22 of the evaporator opposite the second wall surface 112, wherein a second gap 5 exists between the second end 22 of the evaporator and the second wall surface 112, and wherein the second water-conducting rib 33 is arranged within the second gap 5, and wherein one end of the second water-conducting rib 33 is connected to the second wall surface 112, while the other end of the second water-conducting rib 33, namely the free end of the second water-conducting rib 33, rests against the second end 22 of the evaporator. The arrangement of the free end of the second water-conducting rib 33 allows the flow path of the condensate on the second wall surface 112 to be interrupted.Since the free end of the second water conduit rib 33 rests at least against the underside of the second end 22 of the evaporator, the second water conduit rib 33 can guide the condensate from the second wall surface 112 to the evaporator 2, thus preventing the condensate from flowing out of the second wall surface 112 and improving the user experience.

[0040] Optionally, the second water conduit rib 33 is arranged at an angle, with the lower end of the second water conduit rib 33 being inclined towards the front, which facilitates the guidance of the condensate through the second water conduit rib 33.

[0041] In some embodiments, the second water conduit ribs 33 are provided in a number of at least 2, wherein the free end of one of the second water conduit ribs 33 rests on the underside of the second end 22 of the evaporator, while the free end of the other of the second water conduit ribs 33 rests on the top side of the second end 22 of the evaporator.

[0042] In particular, as in Fig. Figure 3 shows the two second water-conducting ribs 33 arranged at intervals in the front-to-back direction, with one of the second water-conducting ribs 33 located at the front and the other at the rear. The upper end of the second water-conducting rib 33 located at the front is connected to the second wall surface 112, while the lower end of the second water-conducting rib 33 located at the front rests against the underside of the second end 22 of the evaporator. The upper end of the second water-conducting rib 33 located at the rear is connected to the second wall surface 112, while the lower end of the second water-conducting rib 33 located at the rear rests against the top of the second end 22 of the evaporator.The arrangement of the two second water-conducting ribs 33 blocks the flow path of the condensate on the second wall surface 112 from the front and back to prevent the condensate from flowing downwards along the second wall surface 112, thus guaranteeing the guiding effect of the second water-conducting ribs 33 and improving the user experience.

[0043] Furthermore, the free end of the second water conduit rib 33 engages by 0.5 mm-1 mm into the second end 22 of the evaporator to further guarantee the guiding effect of the second water conduit rib 33.

[0044] Furthermore, the second water conduit rib 33 is arranged inclined forwards in a top-to-bottom direction to better direct the condensate to the evaporator 2.

[0045] In some embodiments, the second end 22 of the evaporator has an upper side surface and a lower side surface, wherein the at least two second water conduit ribs 33 are located between the upper side surface and the lower side surface of the second end of the evaporator 2.

[0046] In particular, as shown in Fig. Figure 3 shows that the second end 22 of the evaporator has a second sealing surface 223, wherein the upper side surface 221 of the second end of the evaporator, the second sealing surface 223, and the lower side surface 222 of the second end of the evaporator are connected successively, and wherein the lower end of the second water-conducting rib 33 abuts the second sealing surface 223. The second water-conducting rib 33 located at the rear is arranged adjacent to the upper side surface 221 of the second end of the evaporator, while the second water-conducting rib 33 located at the front is arranged adjacent to the lower side surface 222 of the second end of the evaporator. In the present embodiment, the second water-conducting rib 33 is arranged between the upper side surface 221 of the second end of the evaporator and the lower side surface 222 of the second end of the evaporator.This allows the second water conduit rib 33 to guide the condensate from the second wall surface 112 to the evaporator 2, thus improving the guiding effect.

[0047] In some embodiments, the water conduit assembly 3 further comprises a second water-absorbing element 34, wherein the second water-absorbing element 34 is arranged between the second wall surface 112 and the second end 22 of the evaporator and is located between two adjacent second water conduit ribs 33.

[0048] In particular, as in Fig. Figure 3 shows the upper end of the second water-absorbing element 34 against the second wall surface 112, while the lower end of the second water-absorbing element 34 rests against a part of the second sealing surface 223 of the second end 22 of the evaporator, thereby creating a sealed connection between the evaporator 2 and the second wall surface 112.

[0049] When the second water-absorbing element 34 comes into contact with condensation, it absorbs water. When the second water-absorbing element 34 becomes saturated, it overflows. The overflowing portion of the condensation then flows along the surface of the second wall surface 112. In the present embodiment, the second water-conducting rib 33 is arranged on the front and back of the first water-absorbing element 32. This directs the portion of the condensation overflowing from the second water-absorbing element 34 to the evaporator 2. This prevents the condensation from flowing out of the ventilation opening, thus improving the user experience.

[0050] Furthermore, in the present embodiment, the position of the second water-conducting rib 33 can be limited by the arrangement of the second water-absorbing element 34. This standardizes the arrangement position of the second water-absorbing element 34 and improves the uniformity of its arrangement position.

[0051] Furthermore, the second water-absorbing element 34 is connected to the second end 22 of the evaporator by gluing.

[0052] Furthermore, the second water-absorbing element 34 is a sponge.

[0053] In some embodiments, the indoor unit body 1 comprises a base 12 and an air guide frame 13, the air guide frame 13 being detachably connected to the base 12. One wall surface 111 and the second wall surface 112 are formed on the base 12, and the other wall surface 111 and the second wall surface 112 are formed on the air guide frame 13.

[0054] In particular, in the embodiment according to Fig. 1. The air guide frame 13 is installed on the base 12, with the first wall surface 111 being formed on the base 12 and the second wall surface 112 on the air guide frame 13. In the present embodiment, a first water guide rib 31 is arranged on the base 12, with a second water guide rib 33 being arranged at the lower end of the air guide frame 13, and with the evaporator 2 being arranged on the base 12, which facilitates the first end 21 of the evaporator resting on the base 12 and simultaneously the second end 22 of the evaporator resting on the air guide frame 13, thereby facilitating the installation of the first water-absorbing element 32 and the second water-absorbing element 34 and improving installation efficiency.

[0055] In some other embodiments, the first wall surface 111 is formed on the air guide frame 13 and the second wall surface 112 on the base 12, wherein the first end 21 of the evaporator is the front end of the evaporator 2 and the second end 22 of the evaporator is the rear end of the evaporator 2, and wherein the first end 21 of the evaporator is opposite the first wall surface 111 formed on the air guide frame 13 and the second end 22 of the evaporator is opposite the second wall surface 112 formed on the base 12, and wherein the first water-conducting rib 31 is arranged on the first wall surface 111, and wherein the free end of the first water-conducting rib 31 rests against the underside of the first end 21 of the evaporator, by the first water-conducting rib 31 resting against the first end 21 of the evaporator, the flow path of the condensate on the first wall surface 111 can be interrupted. become,to direct the condensate on the first wall surface 111 to the evaporator 2; the second water-conducting rib 33 is arranged on the second wall surface 112, with the free end of the second water-conducting rib 33 resting against the underside of the second end 22 of the evaporator. By resting the second water-conducting rib 33 against the second end 22 of the evaporator, the condensate on the second wall surface 112 can flow along the extension direction of the second water-conducting rib 33 to the evaporator 2 and flow along the evaporator 2 into the water collection tray 7. The arrangement of the first water-conducting rib 31 and the second water-conducting rib 33 prevents the condensate from overflowing on the first wall surface 111 and the second wall surface 112, thus improving the user experience.

[0056] Furthermore, at least two second water conduit ribs 33 are arranged on the air guide frame 13, which improves the strength of the air guide frame 13.

[0057] Furthermore, the first water conduit rib 31 is formed in one piece with the base 12, and the second water conduit rib 33 is formed in one piece with the air guide frame 13.

[0058] In some embodiments, the indoor unit body 1 comprises an air inlet 14 and an air outlet 15, wherein the air inlet 14 is associated with the installation cavity 11 and the air outlet 15 is associated with the installation cavity 11, and wherein the air inlet 14 is located at the lower end of the indoor unit body 1 and the air outlet 15 is located at the upper end of the indoor unit body 1.

[0059] In particular, as in Fig. Figure 1 shows the air inlet 14 arranged at the lower end of the base 12, the evaporator 2 projecting towards the air inlet 14, and the front end of the air guide frame 13 being open to form the air outlet 15, and the airflow entering the indoor unit 100 from the lower air inlet 14 being able to perform heat exchange with the V-shaped wall surface of the evaporator 2, and the heat-exchanged airflow being expelled through the air outlet 15 to improve the heat exchange effect of the indoor unit 100.

[0060] Since the air inlet 14 is located at the lower end of the base 12 and the front end of the air guide frame 13 is open to form the air outlet 15, the indoor unit 100 in the embodiment of this disclosure can be installed flush with the ceiling or with a reserved installation clearance. It is understood that, since the ambient air does not need to enter the indoor unit 100 directly from above the base 12, the distance between the indoor unit of the air conditioner and the ceiling or the wall above it can be significantly reduced or eliminated entirely. This improves the use of space within the room, particularly in interiors with low ceilings, and effectively reduces or eliminates the feeling of confinement. Therefore, the indoor unit 100 of the embodiment of this disclosure requires only minimal installation space.The installation space only needs to accommodate the indoor unit 100 itself; no additional space above the unit is required for air intake or exhaust. This significantly expands the applicability of the air conditioner's indoor unit.

[0061] In this embodiment, the indoor unit 100 can be installed with a gap of 20 to 30 centimeters between itself and the ceiling or the wall above it. This facilitates the mounting of the indoor unit 100 to the wall structure. Firstly, it prevents abrasion on the upper end face of the indoor unit 100 when installed flush with the ceiling. Secondly, maintaining this installation distance allows the indoor unit 100 to retain its original mounting configuration, thus simplifying installation for technicians.

[0062] In some embodiments, the indoor unit 100 further comprises an evaporator support 6 and a water collection tray 7, wherein the evaporator support 6 and the water collection tray 7 are each arranged in the installation cavity 11, and wherein the evaporator 2 is arranged on the evaporator support 6, and wherein the evaporator support 6 comprises a support body 61 and a water barrier plate 62, and wherein the water barrier plate 62 is arranged on one side of the support body 61 in the longitudinal direction of the indoor unit 100, and wherein the water collection tray 7 is located at the bottom of the evaporator support 6 and the evaporator 2.

[0063] In particular, the water barrier plate 62 is arranged on one side of the mounting body 61 on which the metal tubes are located. The water barrier plate 62 projects towards the side of the mounting body 61 facing away from the evaporator 2, being positioned at the outer edge of the mounting body 61 and gradually extending towards the lower end of the mounting body 61. The water collection tray 7 is arranged in the installation cavity 11 and is located below the evaporator mounting bracket 6. Since condensation easily accumulates around the metal tubes, the water barrier plate 62 serves to collect and drain the condensation dripping from the metal tubes.The condensate collected on the mounting bracket 61 and the water barrier plate 62 can be completely channeled downwards into the water collection tray 7, preventing it from dripping directly downwards and causing leakage problems with the indoor unit of the air conditioner. In this way, the evaporator mounting bracket 6 channels the condensate generated by the operation of the evaporator 2, thus preventing leakage problems with the indoor unit and improving the user experience.

[0064] As in Fig. As shown in Figure 4, the evaporator holder 6 is located on the right side of the evaporator 2, which is installed on the holder body 61, with the water barrier plate 62 being located at the right end of the holder body 61.
