Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit and an air conditioner. Background Technology

[0002] When an air conditioner's indoor unit is cooling, the fan and its internal motor power cord are affected by the low temperature, making them prone to condensation. To address this, an insulation layer is usually applied to the outer wall of the fan to reduce condensation. However, for the power cord, which needs to connect electrically to other circuits, similar insulation is impractical. If the condensation on the power cord cannot be effectively controlled, it can negatively impact the user experience, such as condensation dripping onto the floor; more seriously, condensation may flow into the motor, threatening its safety and reliability.

[0005] The air duct shell has a side wall through which a wire is provided. The side wall has a bottom end near the ground. The wire extends to the bottom end, bends, and extends away from the ground.

[0006] A chassis is located at the bottom of the air duct shell, and the chassis is used to collect condensate on the side wall and the conductor.

[0007] In one embodiment, the indoor unit further includes a limiting structure disposed on the side wall, the limiting structure being used to limit the wire to the side wall.

[0008] In one embodiment, the limiting structure includes:

[0009] A first limiting part is provided at the bottom end, and the wire is wound around the first limiting part;

[0010] The second limiting part is provided on the side wall and is located on the side of the first limiting part away from the chassis. The wire is connected to the first limiting part and the second limiting part in sequence.

[0011] In one embodiment, a plurality of second limiting portions are provided, and the plurality of second limiting portions are spaced apart along the edge of the sidewall.

[0012] In one embodiment, the first limiting part is configured as a protrusion at the bottom end, the protrusion extending toward the chassis side, and the wire is wound around the protrusion; and / or, the second limiting part is configured as a buckle, the buckle having a limiting space, the wire engaging with the buckle and being accommodated within the limiting space.

[0013] In one embodiment, a flow guide port is provided at the bottom end, and a flow diversion structure is also provided on the side wall. The flow diversion structure is provided on the side wall and is used to guide the condensate on the side wall to the flow guide port.

[0014] In one embodiment, the drainage structure includes:

[0015] A drainage rib assembly is provided in the middle of the side wall, and the drainage rib assembly is used to guide the condensate on the side wall to the drainage port;

[0016] A baffle rib assembly is provided at the edge of the sidewall to prevent condensate on the sidewall from flowing out from the edge of the sidewall.

[0017] In one embodiment, the duct housing is configured as a volute, with an air outlet at the top of the volute, and the baffle rib assembly includes:

[0018] The first baffle rib has one end joined to one side edge of the air outlet, and the other end extends to the air guide.

[0019] The second baffle rib has one end joined to one side edge of the air outlet, and the other end extends obliquely toward the first baffle rib.

[0021] In one embodiment, the drainage rib group has a first protrusion height, and the flow-blocking rib group has a second protrusion height, wherein the second protrusion height is greater than the first protrusion height.

[0022] In one embodiment, the duct housing is further provided with a splash-proof structure, which is located at the flow guide port and is used to collect condensate on the side wall and the wire and guide it into the chassis.

After extending to the bottom end, they bend and extend in the opposite direction. Thus, the part of the wire that bends at the bottom end is at the lowest point in the entire extension path of the wire. When condensate is generated on the wire, the condensate can flow down the wire to the bottom end under the action of gravity and drip into the base below. This solution adjusts the extension path of the wire so that the condensate on the wire can be caught by the base, preventing it from dripping to the outside and affecting the user experience. At the same time, the above arrangement of the wires also prevents condensate from flowing into the duct housing, reducing the risk of water entering the motor inside the duct housing and improving the reliability and safety of the duct housing operation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0041] When the indoor unit of an air conditioner is cooling, condensation easily forms on the duct casing 100 and its power cord due to the low temperature. While applying insulation to the outer wall of the duct casing 100 can reduce condensation, it's not convenient to apply insulation to the power cord. If the condensation on the power cord is not effectively treated, it may drip onto the floor, affecting the user experience; in more serious cases, the condensation may flow into the motor, affecting its safety and reliability.

[0042] Therefore, this technical solution proposes an indoor unit, including: a duct housing 100, the duct housing 100 having a side wall 10, a wire 110 extending through the side wall 10, the side wall 10 having a bottom end 20 near the ground, the wire 110 extending to the bottom end 20 and then bending and extending away from the ground; and a chassis 200, located at the bottom of the duct housing 100, the chassis 200 being used to collect condensate on the side wall 10 and the wire 110. In this invention, the duct housing 100 has a side wall 10, and a base 200 is provided at the bottom of the duct housing 100. Condensate on the side wall 10 can drip downwards onto the base 200. Additionally, the wire 110 on the duct housing 100 can pass through the side wall 10 and extend towards the bottom end 20 near the ground on the side wall 10. After reaching the bottom end 20, it bends and extends in the opposite direction. Thus, along the entire extension path of the wire 110, the portion where the wire 110 bends at the bottom end 20 is at its lowest point. When condensate forms on the wire 110... Condensate can flow along the conductor 110 to the bottom 20 under gravity and drip into the chassis 200 below. This solution adjusts the extension path of the conductor 110 so that the condensate on the conductor 110 can be received by the chassis 200, preventing it from dripping to the outside and affecting the user experience. At the same time, the above arrangement of the conductor 110 also prevents the condensate on the duct housing 100 from flowing into the duct housing 100, reducing the risk of water entering the motor inside the duct housing 100 and improving the reliability and safety of the duct housing 100 operation.

[0043] like Figures 1 to 6In one embodiment of this utility model, the indoor unit includes a duct housing 100, which can be a cross-flow duct or a centrifugal duct. The duct housing has the aforementioned sidewall 10, which has a bottom end 20 near the ground. Condensate on the sidewall 10 flows to the bottom end 20 under gravity and drips from there. A motor for generating airflow is installed inside the duct housing 100, and the aforementioned wire 110 is connected to the motor. Furthermore, a chassis 200 structure is provided at the bottom of the duct housing 100. The chassis 200 forms part of the air conditioner casing and is located at the bottom of the indoor unit and supported on the ground. Condensate on the duct housing 100 and components such as the evaporator of the indoor unit can drip onto the chassis 200 and be collected there. To prevent condensate on the wire 110 from flowing into the motor, the wire 110 can pass through the middle of the sidewall 10. The wire 110 extends towards the ground (i.e., the side of the chassis 200), reaching the bottom 20 of the side wall 10 and then bending at the bottom 20 before extending in the opposite direction (away from the ground). Thus, the wire 110 forms a water trap at the bottom 20, which is at the lowest point along the entire path of the wire 110. When condensation occurs on the wire 110, the condensation can flow to the water trap under gravity. Finally, the condensation can drip from the water trap and be caught by the chassis 200 below. In this way, the chassis 200 can catch the condensation on the side wall 10 of the duct housing 100 and the wire 110, preventing the condensation from dripping to the outside and improving the user experience. In addition, the water trap also prevents condensation from flowing into the duct housing 100, reducing the possibility of water entering the motor inside the duct housing 100, thereby improving the safety and reliability of the indoor unit operation.

[0044] like Figure 1 and Figure 2 To prevent the wire 110 from changing position during later use, in one embodiment of this utility model, the indoor unit also includes a limiting structure 300. The limiting structure 300 is disposed on the side wall 10 and is used to limit the wire 110 to the side wall 10. The limiting structure 300 can be a buckle or similar structure disposed on the side wall 10. The wire 110 can be connected to the limiting structure 300. After the position of the wire 110 is fixed by the limiting structure 300, it facilitates the straightening of the wire 110 inside the indoor unit, which is beneficial to improving assembly efficiency. It also ensures the stability of the wire 110's position, guaranteeing that the condensate on the wire 110 can always flow from the return bend into the chassis 200 during later use, thus ensuring the reliability of the indoor unit.

[0045] Figure 2 and Figure 3One structural form of the aforementioned limiting structure 300 is given. In this embodiment, the limiting structure 300 includes: a first limiting part 310, which is disposed at the bottom end 20, and a wire 110 is wound around the first limiting part 310; a second limiting part 320, which is disposed on the side wall 10 and is disposed on the side of the first limiting part 310 away from the chassis 200, and the wire 110 is sequentially connected to the first limiting part 310 and the second limiting part 320.

[0046] The first limiting part 310 is provided at the bottom end 20 of the side wall 10. The first limiting part 310 can be a hook or other structure provided at the bottom end 20. The wire 110 can be fixed around the first limiting part 310. The setting of the first limiting part 310 ensures that the lowest point of the wire 110 on the extension path is always at the bottom end 20 of the side wall 10, so that the condensate on the wire 110 can always flow from the bottom end 20 into the chassis 200. Figure 2 and Figure 3 The diagram illustrates one structural form of the first limiting part 310. In this embodiment, the first limiting part 310 is configured as a protrusion at the bottom end 20, extending toward the chassis 200. The wire 110 is wound around the protrusion, and the limiting of the protrusion prevents the wire 110 from detaching. In addition, the second limiting part 320 is provided on the side wall 10 and is further away from the chassis 200 than the first limiting part 310. The second limiting part 320 can be a structure such as a snap-fit, and the wire 110 can be fixed by the second limiting part 320. The setting of the second limiting part 320 ensures that the remaining part of the wire 110 after bending at the bottom end 20 is always higher than the bottom end 20, ensuring that the condensate on the remaining part can also flow to the bottom end 20, preventing the condensate on the wire 110 from flowing to other circuit parts connected to the wire 110, and further ensuring the reliability and safety of the indoor unit operation. Figure 2 and Figure 3 The structure of the second limiting part 320 is also shown. In this embodiment, the second limiting part 320 is configured as a buckle with a limiting space inside. The wire 110 is engaged with the buckle and housed within the limiting space. The buckle limits the position of the wire 110, ensuring its stability. Furthermore, the limiting space can be designed to be larger than the wire 110, allowing other leads besides the wire 110 to be secured by the second limiting part 320. The wire 110 and other leads can then be combined to form a wire harness. During assembly, this harness can be simultaneously aligned and assembled, improving assembly efficiency. In summary, in this solution, the cooperation between the first limiting part 310 and the second limiting part 320 ensures a more secure fixation of the wire 110. Additionally, as... Figure 3 In another embodiment of this utility model, multiple second limiting portions 320 are provided, and the multiple second limiting portions 320 are spaced apart along the edge of the sidewall 10, such as... Figure 1After the wire 110 is connected to the second limiting part 320, the wire 110 can be aligned along the edge of the side wall 10. This isolates the wire 110 from the side wall 10, preventing condensation on the side wall 10 from being blocked by the wire 110 and ensuring that the condensation on both the wire 110 and the side wall 10 can be drained in time. In addition, two or more second limiting parts 320 can be provided to further improve the reliability of the wire 110 fixation.

[0047] like Figure 1 , Figure 3 and Figure 6 To ensure the smooth drainage of condensate on the sidewall 10, in one embodiment, a guide port 120 is provided at the bottom end 20, and a flow-guiding structure 400 is also provided on the sidewall 10. The flow-guiding structure 400 is used to guide the condensate on the sidewall 10 to the guide port 120. The guide port 120 can be a notch formed by the recess of the bottom end 20 or an opening formed by two parallel and spaced ribs on the sidewall 10. In addition, the flow-guiding structure 400 is also provided on the sidewall 10. The flow-guiding structure 400 can be a plurality of flow-guiding ribs provided on the sidewall 10. The flow-guiding structure 400 can cover the entire sidewall 10 and extend to the guide port 120 at the bottom. The condensate on the sidewall 10 can flow to the guide port 120 under the guidance of the flow-guiding structure 400. In this solution, by setting the guide port 120 and the guide structure 400 to guide the flow of the guide port 120, the condensate on the side wall 10 can be collected and discharged in a concentrated manner, which prevents the condensate from flowing turbulently on the side wall 10 and ensures that the condensate on the side wall 10 can be discharged in a timely manner.

[0048] In one embodiment of the present invention, the drainage structure 400 includes: a drainage rib group 410, which is disposed in the middle of the side wall 10, and the drainage rib group 410 is used to guide the condensate on the side wall 10 to the drainage port 120; and a flow-blocking rib group 420, which is disposed at the edge of the side wall 10 to prevent the condensate on the side wall 10 from flowing out from the edge of the side wall 10.

[0049] like Figure 1In this embodiment, the duct housing 100 is a volute, and an air outlet 130 is provided at the top of the duct housing 100. Additionally, the side wall 10 is the side wall 10 on the axial side of the duct housing 100. The center of the duct housing 100 is the location for installing the motor. The guide rib assembly 410 is provided in both the area near the air outlet 130 and the area near the motor. Of course, the guide rib assembly 410 can cover the entire side wall 10, and the guide rib assembly 410 can be composed of multiple protruding ribs. All the ribs extend towards the guide port 120. Condensate generated on the side wall 10 can adhere to the guide rib group 410 under the action of the wall, and extend along the guide rib group 410 under gravity, eventually flowing to the guide port 120. The arrangement of the guide rib group 410 allows the condensate on the side wall 10 to flow into the chassis 200 more quickly. In addition, the arrangement of the guide rib group 410 can also strengthen the overall strength of the air duct shell 100 and improve its reliability. As for the baffle rib group 420, it can be set at the edge of the side wall 10 and extend along the edge of the side wall 10. The baffle rib group 420 can block the condensate flowing towards the edge of the side wall 10, preventing the condensate from flowing out from the edge of the side wall 10, ensuring that the condensate on the side wall 10 ultimately flows to the guide port 120 and is completely received by the chassis 200.

[0050] Figures 3 to 6 The diagram illustrates one structural form of the baffle assembly 420, which includes: a first baffle 421, one end of which is joined to one side edge of the air outlet 130, and the other end extending to the guide port 120; a second baffle 422, one end of which is joined to one side edge of the air outlet 130, and the other end extending obliquely toward the first baffle 421; and a third baffle 423, which is disposed on both sides of the side wall 10 separately from the first baffle 421, and extends to the guide port 120. The first baffle 421 prevents condensate from flowing out from its edge. Condensate flowing to the first baffle 421 can also flow to the guide port 120 under the guidance of the first baffle 421. The second baffle 422 extends obliquely toward the first guide rib, so that the condensate flowing to the second baffle 422 can flow toward the first guide rib under the guidance of the second guide rib and eventually drip onto the guide rib group 410 set between the first guide rib and the second guide rib, and finally flow to the guide port 120. The third baffle 423 is set on opposite sides of the side wall 10, respectively, and the third baffle 423 plays the same role as the first baffle 421, preventing condensate from flowing out from the edge where the third baffle 423 is located, and guiding the condensate to the guide port 120.

[0051] In one embodiment of this utility model, the drainage rib group 410 has a first protrusion height, and the flow-blocking rib group 420 has a second protrusion height. The second protrusion height is greater than the first protrusion height. This configuration ensures that the condensate on the drainage rib group 410 will not flow past the flow-blocking rib group 420 and outward when it flows to the flow-blocking rib group 420, thus ensuring the effect of the flow-blocking rib group 420 in blocking the condensate.

[0052] like Figure 3 In one embodiment of this utility model, a splash-proof structure 500 is also provided on the duct housing 100. The splash-proof structure 500 is located at the guide port 120 and is used to collect condensate water on the side wall 10 and the wire 110 and guide it into the chassis 200. Specifically, the splash-proof structure 500 is located below the guide port 120 of the duct housing 100. This splash-proof structure 500 can collect condensate water dripping from the guide port 120 and guide it into the chassis 200. In this solution, by providing the splash-proof structure 500 to guide the condensate water on the side wall 10 of the duct housing, it can prevent the condensate water on the side wall 10 from dripping onto the outside of the chassis 200, and it can also prevent the condensate water dripping onto the chassis 200 and then splashing onto the outside of the chassis 200. This solves the technical problem of condensate water inside the indoor unit easily splashing onto the ground and improves the user experience.

[0053] Figure 6 The specific structure of the splash-proof structure 500 is shown. In this embodiment, the splash-proof structure 500 includes: a receiving part 510, which is located below the air guide port 120 and engages with the edge of the chassis 200; and a connecting part 520, which connects the air duct shell 100 and the receiving part 510.

[0054] The receiving part 510 is a plate-shaped structure. It is located below the side wall 10 and is joined to the edge of the chassis 200. This effectively increases the height of the side wall 10 of the chassis 200, thereby preventing condensate from splashing out of the chassis 200. The connecting part 520 can be integrally formed with the receiving part 510 and can be fixed to the bottom of the air duct shell 100 by means of screws or other methods. The condensate on the side wall 10 can drip onto the side wall 10 of the receiving part 510 facing the chassis 200 and enter the chassis 200 below under the guidance of the receiving part 510. This arrangement can prevent the condensate on the side wall 10 from dripping onto the outside of the chassis 200. In another embodiment, the connector and receiving part 510 can be integrally formed with the air duct shell 100, so as to ensure that the position between the splash-proof structure 500 and the air duct shell 100 can remain relatively stable before and after the indoor unit is assembled, and ensure that the condensate on the side wall 10 can be ultimately received by the chassis 200.
