[0038] Combination Figure 1 and Figure 2 As shown, the indoor unit of the air conditioner in this embodiment includes a housing 1, a heat exchanger 4, a water receiving tray 5, a fan 6, a first air guide plate 7, and a guiding component 8.

[0039] The housing 1 has a first air outlet 2 that discharges air downwards and a second air outlet 3 that discharges air horizontally. The heat exchanger 4 is installed inside the housing 1 and is used to circulate refrigerant that exchanges heat with the air. The air that has exchanged heat with the heat exchanger 4 is discharged through the first air outlet or the second air outlet.

[0040] The water receiving tray 5 is located below the heat exchanger 4 and is situated on opposite sides of the first air outlet 2, respectively, as is the second air outlet 3. The fan 6 is housed within the casing 1 and configured to provide power for air to flow through the heat exchanger 4 to the first air outlet 2 and / or the second air outlet 3.

[0041] The first air outlet 2 and the second air outlet 3 are located on the same side of the heat exchanger 4. The airflow provided by the fan 6 flows through the heat exchanger 4 to the positions of the first air outlet 2 and the second air outlet 3. Therefore, the airflow direction can be adjusted simply by controlling the opening and closing of the first air outlet 2 and the second air outlet 3.

[0042] The first air guide plate 7 is movably disposed relative to the housing 1 to switch between a first position blocking the first air outlet 2 and a second position blocking the second air outlet 3. In the first position, the first air guide plate 7 extends from the side of the first air outlet 2 away from the water collection tray 5 to the side adjacent to the water collection tray 5. A guiding member 8 is disposed on the lower surface of the first air guide plate 7 when it is in the first position to guide the condensate on the lower surface toward the water collection tray 5.

[0043] When it is necessary to adjust the indoor unit of the air conditioner to the horizontal air outlet mode (for example, when the air conditioner is in the cooling mode), the first air guide plate 7 is switched to the first position to block the first air outlet 2 and open the second air outlet 3; when it is necessary to adjust the indoor unit of the air conditioner to the downward air outlet mode (for example, when the air conditioner is in the heating mode), the first air guide plate 7 is switched to the second position to block the second air outlet 3 and open the first air outlet 2.

[0044] In this embodiment, the indoor unit of the air conditioner also includes a second air guide plate 10 for blocking the second air outlet 3. When it is necessary to close the second air outlet 3, the first air guide plate 7 and the second air guide plate 10 are switched to the position of blocking the second air outlet 3, and the first air guide plate 7 is located below the second air guide plate 10.

[0045] When the air conditioner is in cooling mode and the horizontal air outlet mode is selected, the first air guide plate 7 blocks and closes the first air outlet 2. The air that has exchanged heat with the heat exchanger 4 is discharged through the second air outlet 3. The first air guide plate 7 is at a lower temperature due to the influence of the air that has exchanged heat with the heat exchanger 4. At this time, the outer surface of the first air guide plate 7 (that is, the lower surface of the first air guide plate 7 in the first position) is in contact with the indoor air, so condensation is likely to appear on the outer surface of the first air guide plate 7.

[0046] To prevent condensation from dripping onto the room from the outer surface of the first air guide plate 7, a guiding component 8 is provided on the outer surface of the first air guide plate 7. The guiding component 8 guides the condensation from the outer surface of the first air guide plate 7 to the water collection tray 5, thereby improving the problem of condensation from the indoor unit of the air conditioner easily leaking and dripping onto the room.

[0047] In some embodiments, the guiding component 8 includes a moisture-absorbing material layer attached to the lower surface of the first air guide plate 7. The moisture-absorbing material layer is in contact with the outer surface of the first air guide plate 7, and the moisture-absorbing material layer is made of a highly absorbent material (such as a moisture-absorbing fiber layer, silica gel particles, or a hydrophilic polymer). This moisture-absorbing material layer quickly absorbs condensate through capillary action and adsorption, and guides it to the drip tray 5, while preventing moisture from accumulating inside the absorbent layer, which could lead to secondary evaporation or mold growth.

[0048] In some embodiments, a moisture-absorbing material layer is disposed at one end of the first air guide plate 7 adjacent to the water collection tray 5 in the first position, and extends from the outer side to the inner side of the edge of the first air outlet 2. When the first air guide plate 7 is in the first position blocking the first air outlet 2, one end of the first air guide plate 7 adjacent to the water collection tray 5 covers the edge of the first air outlet 2. The condensate on the outer surface of the first air guide plate 7 will move along the first air guide plate 7 due to surface tension, but it will be blocked when it reaches the edge of the first air outlet 2, making it easy to drip. The moisture-absorbing material layer extending from the outer side to the inner side of the edge of the first air outlet 2 guides the condensate to the water collection tray through capillary action, thus improving the problem of condensate generated by the indoor unit of the air conditioner easily leaking and dripping into the room.

[0049] In some embodiments, the indoor unit of the air conditioner further includes a thermal insulation layer 11 disposed on one side of the inner cavity adjacent to the moisture-absorbing material layer 1. This thermal insulation layer 11, through its thermal blocking effect, isolates the cold bridge effect between the water collection tray and the air outlet component, preventing condensation or heat transfer loss due to temperature differences. The thermal insulation layer 11 is made of a material with low thermal conductivity (such as polyurethane foam, aluminum silicate fiber, or aerogel material) and has a thickness of 2-5 mm.

[0050] In some embodiments, the thermal insulation material layer 11 is attached to the outer surface of the first air guide plate 7, that is, to the lower surface of the first air guide plate 7 when it is in the first position. The thermal insulation material layer 11 and the moisture-absorbing material layer form a composite layer structure. This composite structure combines water absorption and thermal insulation: the upper layer of the composite structure is a thermal insulation material, and the lower layer is a moisture-absorbing material.

[0051] In other embodiments, the insulation material layer 11 is attached to the inner surface of the first air guide plate 7, that is, to the upper surface of the first air guide plate 7 when it is in the first position.

[0052] In some embodiments, the height of the lower surface of the first air guide plate 7 gradually decreases along the direction close to the water receiving tray 5. The first air guide plate 7 is generally inclined, and its inclination angle is optimized to be no less than 20° with the horizontal, ensuring that under the action of gravity, condensate can flow smoothly along the outer surface of the first air guide plate.

[0053] In some embodiments, the lower surface of the first air guide plate 7 in the first position is a smooth surface. This surface is made of a low-friction coefficient material (such as a polytetrafluoroethylene coating or a polymer), which not only reduces the resistance to condensate adhesion but also guides the water flow along a predetermined path through surface tension. The condensate slides from the surface of the air guide plate to the absorbent layer below, achieving efficient collection.

[0054] In some embodiments, the indoor unit of the air conditioner further includes a one-way valve assembly 9 disposed between the guide member 8 and the drip tray 5. The one-way valve assembly 9 is configured to allow condensate to flow from the guide member 8 to the drip tray 5 and to prevent condensate from flowing back to the guide member 8. This helps to ensure that the condensate flows to the drip tray and prevents the condensate from flowing back out of the first air outlet 2 and dripping into the room.

[0055] In some embodiments, the one-way valve assembly 9 includes a support member 9a and a valve plate 9b. The support member 9a is disposed above and spaced apart from the water tray 5. The valve plate 9b includes an upper end hinged to the support member 9a and a lower end abutting against the water tray 5 under gravity. Horizontally, the upper and lower ends are located on the side of the upper end away from the first air guide plate 7, so that the valve plate 9b is blocked from rotating by the bottom of the water tray 5 when subjected to a force toward the side of the first air guide plate 7 (e.g., the pressure of air from the side of the heat exchanger 4), thereby achieving reverse closure. The valve plate 9b rotates toward the side away from the first air guide plate 7 when subjected to a force toward the side of the water tray 5 (e.g., the pressure from condensate), thereby forming a gap at the lower end of the valve plate 9b that allows condensate to flow. The support member 9a is connected to the housing 1 via a connecting member 12.

[0056] To achieve unidirectional flow of condensate, a one-way valve assembly 9 is integrated into the structure. The core of the one-way valve assembly 9 is a gravity-driven mechanical valve plate with a one-way flow guiding function: when condensate seeps down through the moisture-absorbing material layer, the gravity valve plate remains closed due to its own weight, and the water flow gathers and opens the valve to enter the water receiving tray.

[0057] Wind pressure blocking function: When airflow (such as the wind pressure during air conditioning operation) attempts to push valve plate 9b in the opposite direction (i.e., towards the side of the first air outlet 2), valve plate 9b closes in the opposite direction due to the one-way valve structure (abutting against the bottom of the drip tray 5), preventing condensate backflow or the wind deflector from opening abnormally due to wind pressure. This design ensures the stability of the system under complex operating conditions through the self-adaptability of the mechanical structure.

[0058] In some embodiments, the supporting member 9a includes a plate-shaped member disposed at one end of the first air guide plate 7 in the first position adjacent to the water receiving tray 5, to block the air blown from the heat exchanger 4 toward the second air outlet 3 from blowing onto the water flowing toward the water receiving tray 5 via the guide member 8. This facilitates the smooth flow of condensate to the water receiving tray 5 and prevents condensate from splashing due to airflow or seeping out from the edge of the first air outlet 2 and the junction of the first air guide plate 7.

[0059] In some embodiments, the supporting member 9a includes a plate-shaped member disposed below one end of the heat exchanger 4 adjacent to the first air outlet 2. The height of the plate-shaped member gradually decreases in the direction away from the first air outlet 2 to guide the condensate generated by the heat exchanger 4 to the drip tray 5. The condensate generated on the heat exchanger 4 is guided by the plate-shaped member to the top of the drip tray 5 and drips into the drip tray 5 to prevent the condensate from seeping out through the gaps in the housing 1 and dripping into the room.

[0060] In some embodiments, the water receiving tray 5 includes a water receiving tray body 5a and a transition platform 5b disposed between the water receiving tray body 5a and the first air outlet 2. The transition platform 5b is higher than the water receiving tray body 5a and lower than the first air guide plate 7, and the lower end of the valve plate 9b abuts against the transition platform.

[0061] The condensate in the drip tray 5 first flows to the lower drip tray body 5a. The probability of water accumulation at the transition platform 5b is low. The lower end of the valve plate 9b cooperates with the transition platform 5b, which helps to prevent water accumulation from affecting the operation of the valve plate 9b, thereby ensuring that the one-way valve assembly 9 works effectively.

[0062] In the indoor unit of this air conditioner embodiment, the first air guide plate 7 and the water collection tray 5 work together. When the first air guide plate 7 is in its lowest position (i.e., the first position with the lower air outlet closed), its upper short plate surface (valve plate 9b) is tightly attached to the surface of the water collection tray 5, forming a physical isolation barrier, effectively preventing the airflow generated by the heat exchanger 4 from directly impacting the area of ​​the water collection tray 5. This design, through the sealing of the contact surface, prevents cold air from leaking from the gaps in the air outlet, while also preventing condensate from spreading to other components due to airflow disturbance.

[0063] The main technical effects achieved by the technical solution in this embodiment are as follows:

[0064] 1. A flow guiding component 8 is installed to guide the condensate generated when the first air guide plate 7 is closed to the water receiving tray 5, so as to prevent condensate from accumulating inside the equipment or affecting the operation of the air outlet components.

[0065] 2. A composite structure of moisture-absorbing material layer 8 and heat insulation material layer 11 (such as moisture-absorbing fiber layer + low thermal conductivity insulation layer) is adopted to effectively block the cold bridge effect between the water collection tray 5 and the air outlet component, and prevent condensation or increased energy consumption caused by heat transfer.

[0066] 3. The integrated one-way valve assembly 9 ensures that the condensate flows in one direction to the water collection tray 5, while the gravity valve blocks the impact of the reverse wind pressure on the wind deflector, preventing the wind deflector from opening or the condensate from flowing back due to abnormal wind pressure.

[0067] According to another aspect of the present invention, an air conditioning device is also provided, which includes the above-mentioned indoor air conditioning unit.

[0068] The above are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
