The present disclosure relates to the field of air conditioners, and more particularly, to an air duct member, a ventilation and heat exchange component, and an air conditioner.
In the related art, a conventional air conditioner is provided with an air duct structure. When the air conditioner is in a cooling operation mode, condensed water is likely to be generated on an outer surface of a second air duct wall of the air duct structure, and flows downwardly into the air conditioner by gravity. If the condensed water cannot flow into a water receiving pan of the air conditioner, it is likely to cause a short circuit in the air conditioner. In addition, in the related art, an insulation layer is disposed at the outer surface of the second air duct wall. The insulation layer may be a sponge, which can absorb the condensed water on the outer surface of the second air duct wall. The sponge is susceptible to mold and bacterial growth after repeated dry-wet cycles over a long period of time, generating an unpleasant odor. In addition, arranging the sponge would increase assembly steps and wastes manpower. Also, more materials are used, resulting in a waste of resources.
The present disclosure aims to solve at least one of the technical problems in the related art. To this end, embodiments of the present disclosure provide an air duct member, which can avoid an unpleasant odor generated by the air duct member, simplify assembly steps of the air duct member, and save materials and resources.

An air duct member 101 according to an embodiment of the present disclosure will be described below with reference to
As illustrated in
Further, the water receiving portion 30 is dispose at a lower end of the air duct portion 10. Further, the water receiving portion 30 defines a water receiving recess 31 located outside the cross-flow air duct 23. The water receiving recess 31 has an open upper end and is located at a side of the second air duct wall 22 away from the first air duct wall 21. When there is condensed water on an outer surface of the second air duct wall 22 away from the first air duct wall 21, i.e., when there is condensed water on the outer surface of the second air duct wall 22, the condensed water flows down along the outer surface of the second air duct wall 22 by gravity. Since the water receiving recess 31 is formed at the side of the second air duct wall 22 away from the first air duct wall 21, the water receiving recess 31 may be adapted to receive the condensed water flowing down along the outer surface of the second air duct wall 22.
In some embodiments, when the air conditioner 400 is in a cooling mode, a gas inside the cross-flow air duct 23 has a low temperature. Since a temperature of an outer surface of the air duct structure 20 is approximately the same as an ambient temperature of an indoor space, a temperature of the outer surface of the second air duct wall 22 is greater than the temperature of the gas inside the cross-flow air duct 23. Due to such a temperature difference, water vapors in the air is formed into the condensed water on the outer surface of the second air duct wall 22. Under the action of gravity, the condensed water flows down along the outer surface of the second air duct wall 22. The condensed water may flow into the water receiving recess 31 to avoid gathering of the condensed water on the outer surface of the second air duct wall 22, which can keep the outer surface of the second air duct wall 22 dry. In comparison with the related art, the condensed water generated on the outer surface of the second air duct wall 22 can be collected without providing a thermal insulation layer, such as, a sponge at the outer surface of the second air duct wall 22, which can avoid a situation that the sponge is susceptible to mold and bacterial growth after repeated dry-wet cycles over a long period of time. Therefore, it is possible to prevent the air duct member 101 from generating an unpleasant odor. In addition, a step of arranging the sponge at the outer surface of the second air duct wall 22 is avoided, which can simplify assembly steps of the air duct member 101 and save manpower. Also, materials and resources can be saved.
As a result, by arranging the water receiving portion 30 at the lower end of the air duct portion 10, the condensed water flowing down along the outer surface of the second air duct wall 22 may flow into the water receiving recess 31. In comparison with the related art, there is no need to provide the thermal insulation layer, such as, the sponge on the outer surface of the second air duct wall 22, which can avoid the situation that the sponge is susceptible to mold and bacterial growth after repeated dry-wet cycles over a long period of time. Therefore, it is possible to prevent the air duct member 101 from generating an unpleasant odor. In addition, the step of arranging the sponge at the outer surface of the second air duct wall 22 is avoided, which can simplify the assembly steps of the air duct member 101 and save manpower. Also, materials and resources can be saved.
In some embodiments of the present disclosure, the air duct member 101 may be formed as a plastic member, which is low-cost and lightweight. In this way, manufacturing costs of the air duct member 101 can be lowered to reduce manufacturing costs of the air conditioner 400, enhancing market competitiveness of the air conditioner 400. In addition, a weight of the air duct member 101 can be lowered. When the air duct member 101 is mounted inside the air conditioner 400, a weight of the air conditioner 400 can be reduced, which makes the air conditioner 400 easy to be carried by a user and is conducive to a lightweight design of the air conditioner 400.

In addition, since the water receiving pan 301 in the air conditioner 400 is disposed below the heat exchange assembly 200 and is located close to the rear of the air conditioner 400, by forming the first drainage hole 32 close to the rear end of the water receiving recess 31, the condensed water in the water receiving recess 31 can flow downwardly and be discharged into the water receiving pan 301 when the condensed water flows out of the first drainage hole 32.

Further, a plurality of support portions 40 may be provided between the two adjacent second air duct walls 22. The plurality of support portions 40 is sequentially arranged at intervals in the height direction of the air duct member 101. In addition, a constant spacing distance is formed between any two adjacent support portions 40. By supporting the two adjacent second air duct walls 22 by the plurality of support portions 40 simultaneously, the structural strength of the second air duct wall 22 can be further enhanced to further reinforce the structural strength of the air duct structure 20, preventing the second air duct wall 22 from being deformed.

In some embodiments of the present disclosure, a water collection recess 431 is defined in the support portion 40. The support portion 40 may include a flow guide rib 432 disposed in the water collection recess 431. The flow guide rib 432 is configured to guide water in the water collection recess 431 to flow towards the second drainage hole 41. Further, the upper surface of the support portion 40 may be provided with the flow guide rib 432. The flow guide rib 432 can provide guiding for the condensed water. When the condensed water flows to the upper surface of the support portion 40, the flow guide rib 432 can facilitate flowing of the condensed water at the upper surface of the support portion 40 towards the second drainage hole 41, which facilitates discharge of the condensed water at the upper surface of the support portion 40.
In some embodiments of the present disclosure, as illustrated in
When a wire harness (wire) is arranged between the two adjacent second air duct walls 22, mounting the wire harness at the cable holder 27 can prevent the wire harness from being brought into contact with the outer surface of the second air duct wall 22 to avoid a short-circuit of the wire harness caused when the wire harness encounters the condensed water. Therefore, the use safety of the air conditioner 400 can be increased. Further, after the electronic control box is connected to the motor 1202 by the wire harness, mounting the wire harness at the cable holder 27 can prevent the wire harness from being brought into contact with the outer surface of the second air duct wall 22.
In some embodiments of the present disclosure, the water receiving portion 30 and at least part of a structure of the second air duct wall 22 may be integrally formed. Further, the water receiving portion 30 and the two adjacent second air duct walls 22 are integrally formed. In this way, overall structural strength of the water receiving portion 30 and the air duct structure 20 can be enhanced, and the number of molds developed for manufacturing the air duct member 101 can be reduced to lower development costs of the air duct member 101. As a result, development costs of the air conditioner 400 can be reduced.
In some embodiments of the present disclosure, as illustrated in
In some embodiments of the present disclosure, an angle of the bottom surface of the water receiving recess 31 relative to a horizontal plane may be set to be β, which satisfies a relational expression: 1°≤β≤5°. In this way, the bottom surface of the water receiving recess 31 may be inclined at an appropriate angle, which helps the condensed water flow into the first drainage hole 32 and allows the condensed water to flow in the water receiving recess 31 at an appropriate speed. Therefore, the accumulation of the condensed water in the water receiving recess 31 can be further avoided.
Further, the angle β of the bottom surface of the water receiving recess 31 relative to the horizontal plane may be set to be 3°. In this way, the bottom surface of the water receiving recess 31 may be inclined at a more appropriate angle, which further helps the condensed water flow into the first drainage hole 32 and allows the condensed water to flow in the water receiving recess 31 at a more appropriate speed. Therefore, the accumulation of the condensed water in the water receiving recess 31 can be further avoided, which in turn achieves an appropriate angle of the bottom surface of the water receiving recess 31 relative to the horizontal surface.
In some embodiments of the present disclosure, as illustrated in
In some embodiments of the present disclosure, a plurality of first drainage holes 32 may be formed at the water receiving recess 31. The plurality of first drainage holes 32 are formed at intervals at the water receiving recess 31. The upper end of the flow guide channel 61 may be in communication with each of the plurality of first drainage holes 32. Each of the plurality of first drainage holes 32 and the flow guide channel 61 may directly face towards each other from top and bottom. The third drainage hole 62 and the plurality of first drainage holes 32 do not directly face towards each other from top and bottom. For example, the third drainage hole 62 is formed below the plurality of first drainage holes 32 and is located at the rear side of the first drainage hole 32 directly below the first drainage hole 32. When there is the condensed water in the water receiving recess 31, the condensed water in the water receiving recess 31 flows downwardly into the flow guide channel 61 through the plurality of first drainage holes 32 simultaneously, and then the condensed water in the flow guide channel 61 flows into the water receiving pan 301 through the third drainage hole 62. In this way, a discharge efficiency of the condensed water in the water receiving recess 31 can be improved, and a discharge volume of the water receiving recess 31 per unit of time can be increased, thereby effectively avoiding an overflow of the condensed water in the water receiving recess 31.
In some embodiments of the present disclosure, a first outlet grille (not illustrated) may be disposed at the air duct outlet 25. When the airflow is blown out from the air duct outlet 25, the first outlet grille can allow the airflow to be uniformly blown out from the air duct outlet 25, which can enhance comfort of air blowing.
As illustrated in
As a result, by arranging the water receiving portion 30 at the lower end of the air duct portion 10, the condensed water flowing down along the outer surface of the second air duct wall 22 may flow into the water receiving recess 31. In comparison with the related art, there is no need to provide a thermal insulation layer such as a sponge on the outer surface of the second air duct wall 22, which can avoid the situation that the sponge is susceptible to mold and bacterial growth after repeated dry-wet cycles over a long period of time. Therefore, it is possible to prevent the air duct member 101 from generating an unpleasant odor. In addition, the step of arranging the sponge at the outer surface of the second air duct wall 22 is avoided, which can simplify the assembly steps of the air duct member 101 and save manpower. Also, materials and resources can be saved.
In some embodiments of the present disclosure, the air duct member 101 includes the flow guide portion 60. The water receiving pan 301 may be located at a rear side of the water receiving portion 30 below the water receiving portion 30. The third drainage hole 62 is located at a rear side of the first drainage hole 32 below the first drainage hole 32 and located directly above the water receiving pan 301. In this way, the flow of the condensed water into the water receiving pan 301 can be facilitated.
According to an embodiment of the present disclosure, an air conditioner 400 includes the ventilation and heat exchange component according to any of the above embodiments and a machine body 401. The machine body 401 has an air inlet 402 and an air outlet 403. An inlet grille 404 is mounted at the air inlet 402. The heat exchange assembly 200 may be disposed behind the air duct member 101. The ventilation and heat exchange component is disposed in the machine body 401. The air duct inlet 24 is in communication with the air inlet 402. The air outlet 403 is in communication with the air duct outlet 25. By arranging the water receiving portion 30 at the lower end of the air duct portion 10, the condensed water flowing down along the outer surface of the second air duct wall 22 may flow into the water receiving recess 31. In comparison with the related art, there is no need to provide a thermal insulation layer such as a sponge on the outer surface of the second air duct wall 22, which can avoid the situation that the sponge is susceptible to mold and bacterial growth after repeated dry-wet cycles over a long period of time. Therefore, it is possible to prevent the air duct member 101 from generating an unpleasant odor, and effectively avoid an unpleasant odor in the air blown by the air conditioner 400. In addition, the step of arranging the sponge at the outer surface of the second air duct wall 22 is avoided, which can simplify the assembly steps of the air duct member 101 and save manpower. Also, materials and resources can be saved. Therefore, the manufacturing costs of the air conditioner 400 can be lowered, and an assembly efficiency of the air conditioner 400 can be improved.
In some embodiments of the present disclosure, a second outlet grille (not illustrated) may be disposed at the air outlet 403. The airflow flows to the air outlet 403 when blown out from the air duct outlet 25. When the airflow flows through the air outlet 403, the second outlet grille can allow the gas to be blown uniformly to an indoor environment from the air outlet 403, which further improves the comfort of air blowing.
Further, the air outlet 403 may be provided with a humidification module at an inner side of the air outlet 403. Before the gas flows through the air outlet 403, the humidification module can humidify the gas. The humidified gas is blown from the air outlet 403 to the indoor environment. In this way, humidity of the air blown out by the air conditioner 400 can be increased to keep the indoor environment at appropriate humidity, thereby improving comfort for the user. Further, an air purification module may be provided at the air outlet 403 and/or the air duct outlet 25. Before the gas flows through the air outlet 403 and/or the air duct outlet 25, the air purification module can purify the gas to make the gas blown into the indoor environment clean, which can prevent the gas blown out by the air conditioner 400 from polluting the indoor environment, thereby ensuring the health of the user.
Each of the humidification module and the air purification module may be connected to a controller of the air conditioner 400. The controller can be configured to control operation of each of the humidification module and the air purification module. When the humidification module and/or the air purification module is required to be in operation, the controller controls the humidification module and/or the air purification module to operate. When the humidification module and/or the air purification module are not required to be in operation, the controller controls the humidification module and/or the air purification module to stop operation. Further, the air conditioner 400 may be provided with a control button. An operation mode of the air conditioner 400 may be adjusted by the user by means of the control button. When the humidification module is required to be in operation, the user may press the control button to make the controller control the humidification module to operate. When the air purification module is required to be in operation, the user may press the control button to make the controller control the air purification module to operate.
It should be noted that the machine body 401 may further include an air outlet frame 405 and a base. The air outlet 403 may be formed at the air outlet frame 405 and may be selectively covered or exposed. The air outlet frame 405 may be provided with a front panel at a front side of the air outlet frame 405. The front panel may be movably disposed at the air outlet frame 405 and configured to block the air outlet 403 to cover the air outlet 403. When the air conditioner 400 is required to blow air outwards, the air conditioner 400 controls a driving device to drive the front panel to move to keep the front panel away from the air outlet 403. In this case, the air outlet 403 is in an exposed state. The air conditioner 400 may blow the air towards an outer side from the air outlet 403 to meet the user's needs. When there is no need for the air conditioner 400 to blow the air outwards, the air conditioner 400 controls the driving device to drive the front panel to move to allow the front panel to cover the air outlet 403. In this case, the air outlet 403 is in a covered state. The air conditioner 400 does not blow the air towards the outer side from the air outlet 403. Covering the air outlet 403 by the front panel can prevent objects such as dust and bugs from moving from the air outlet 403 to an inside of the air conditioner 400 when the air conditioner 400 is not in use, ensuring cleanliness inside the air conditioner 400 and the use safety of the air conditioner 400.
Further, the base may be disposed at a lowermost end of the air conditioner 400. The base is configured to support the air conditioner 400 to place the air conditioner 400 on the ground stably, which can prevent the air conditioner 400 from tipping over. Therefore, the use safety of the air conditioner 400 is ensured, and service life of the air conditioner 400 is prolonged.
