Detailed Description
An embodiment of the present invention first provides a wall-mounted air conditioner indoor unit, as shown in fig. 1 and 2, including: the air-conditioning unit comprises a shell 10, an air outlet duct 20, an air deflector 30, an air duct plate 40 and a flow guide plate 50.
An air outlet extending along the transverse direction of the indoor unit of the air conditioner is arranged at the bottom of the front side of the shell 10. The interior of the housing 10 is also provided with an evaporator 83, a cross flow fan 82 and a volute 81. The volute 81 is transversely arranged inside the indoor unit, and the cross flow fan 82 is transversely arranged inside the volute 81. In the present embodiment, the evaporator 83 is a three-stage evaporator, and is disposed at the front upper side outside the cross flow fan 82.
The air outlet duct 20 is disposed inside the casing 10, and an inlet end thereof is connected to an outlet of the volute 81, and an outlet end thereof is communicated with the air outlet. The air outlet duct 20 is used for guiding air, which is subjected to heat exchange between the interior of the volute 81 of the indoor unit of the air conditioner and the evaporator 83, to the air outlet. The outlet duct 20 is defined by an upper duct wall 22 and a lower duct wall 21.
The air deflector 30 is disposed at the air outlet and configured to rotate around a horizontal axis of the indoor unit of the air conditioner to adjust the vertical air outlet direction of the indoor unit of the air conditioner. In this embodiment, the air deflector 30 extends transversely along the indoor unit, and two ends of the air deflector 30 are provided with rotating shafts pivotally connected to the casing 10, and the air deflector 30 can rotate around a connecting line of the rotating shafts at the two ends. In the present embodiment, the air deflector 30 is located at the front upper portion of the air duct plate 40, that is, the air deflector 30 is located at a position close to the upper air duct wall 22 of the air outlet duct 20.
The air duct plate 40 is disposed in a region where the lower air duct wall 21 of the air outlet duct 20 is connected to the air outlet, and the air duct plate 40 controllably extends or retracts along the extending direction of the lower air duct wall 21, so as to adjust the flow guiding length of the air outlet duct 20 and the size of the air outlet region. In the present embodiment, the air duct plate 40 also extends in the lateral direction of the wall-mounted air conditioning indoor unit, and preferably has the same lateral length as that of the air deflector 30. The air duct plate 40 is disposed in a range area of a lower edge of the air outlet. One part of the air duct plate 40 is located inside the air outlet and abuts the lower air duct wall 21, and the other part extends out of the air outlet. The length of the air duct plate 40 extending out of the air outlet portion (the length here refers to the length extending in the front-rear direction of the indoor unit) can be adjusted by moving the air duct plate 40 forward and backward. When the air deflector 30 extends forward, the air outlet duct 20 is extended, and the air outlet direction is changed. Meanwhile, the front end of the air duct plate 40 is closer to the upper edge of the air outlet, so that the air outlet area is reduced, and the air outlet amount is reduced accordingly. When the air deflector 30 retracts backwards, the air outlet duct 20 is relatively shortened, and the air outlet direction is changed. Meanwhile, the air outlet area is enlarged, so that the air outlet quantity is increased. The cross section of the air duct plate 40 is arc-shaped, the curvature of the air duct plate is matched with that of the lower air duct wall 21, and the curvature matching means that the curvatures of the air duct plate 40 and the lower air duct wall 21 or the extension lines of the air duct plate and the lower air duct wall 21 are the same, so that the air duct plate 40 can extend the flow guide length along the extension direction of the air outlet duct 20, and the air flow circulation is facilitated.
When the air-conditioning indoor unit stops working, the air duct plate 40 extends forwards to the maximum distance, at this time, the air deflector 30 correspondingly rotates to a proper angle, and the air deflector 30 and the air duct plate 40 can jointly close the air outlet, as shown in fig. 2. Because the air deflector 30 and the air duct plate 40 both have certain radians, the parts of the air deflector and the air duct plate which jointly seal the air outlet can form a complete cambered surface, so that the appearance is more attractive when the air outlet is closed.
The flow guide plate 50 is movably disposed at the bottom of the outer side of the casing 10, and is used for guiding the air flow below the air outlet outside the air conditioning indoor unit to the front of the air outlet of the air conditioning indoor unit, so that the air outlet of the air conditioning indoor unit is mixed with the air flow outside the air conditioning indoor unit and then sent out. In this embodiment, the drainage plate 50 also extends in the lateral direction of the wall-mounted air conditioning indoor unit. Which is disposed below the air duct plate 40, that is, the flow guide plate 50 and the air duct plate 40 have a certain interval therebetween. The function of the flow guide plate 50 is to introduce the air flow outside the indoor unit and mix the air flow flowing out from the indoor unit to form mixed air. When increasing the air output, use the air of room temperature and by the cold air or the hot-air that the air outlet sent out for supply air current temperature is suitable, reaches and lets the comfortable effect of user's body feel.
The duct plate 40 of the present embodiment is accommodated in a space defined by the lower duct wall 21 and the casing 10, and one surface thereof abuts against the outer surface of the lower duct wall 21. The junction of the housing 10 and the lower duct wall 21 has an opening that allows the duct plate 40 to protrude. That is, the duct plate 40 moves back and forth against the lower duct wall 21. The size of the opening may be set according to the thickness of the air duct plate 40.
In the present embodiment, the air duct plate 40 is driven by a motor. Specifically, the wall-mounted air conditioner indoor unit further includes: drive motor, gear 71. The gear 71 is disposed at the output end of the driving motor and located inside the space defined by the lower duct wall 21 and the housing 10. One side of the lower air duct plate 40 is provided with a rack, and the other side of the lower air duct plate abuts against the outer side surface of the lower air duct wall 21. The gear 71 is engaged with the rack to drive the air duct plate 40 to move. When the gear 71 rotates in the forward direction, the air duct plate 40 extends to the outside of the air outlet, and when the gear 71 rotates in the reverse direction, the air duct plate 40 retracts to the inside of the air outlet.
The air duct plate 40 and the flow guide plate 50 are an integral piece, and move synchronously. In this embodiment, the wall-mounted air conditioning indoor unit further includes: two connecting plates 60. Two connecting plates 60 are respectively disposed at both lateral ends of the air duct plate 40, and each connecting plate 60 is used to fixedly connect the end portions of the same side of the air duct plate 40 and the flow guide plate 50, so that the air duct plate 40 and the flow guide plate 50 form a single piece.
In order to achieve better air guiding and blowing effects, in the present embodiment, it is preferable that the front ends of the air duct plate 40 and the air guiding plate 50 are flush, as shown in fig. 3, so that the air blown from the air outlet and the air outside the indoor unit reach the same position and mix at the same time, thereby preventing the air flow from changing its blowing direction due to the pressure difference between the two air flows. The flow guide plate 50 is a flat plate and is parallel to a tangent plane of the air duct plate 40 near the front end portion, and is disposed such that the two air flows flow in parallel to each other to achieve uniform mixing.
When the air conditioner indoor unit is in the air duct plate 40, three preset working positions are provided, including a first position, a second position and a third position, wherein the extending length of the air duct plate 40 relative to the lower air duct wall 21 is increased in sequence. That is, the air duct plate 40 has the shortest protruding length in the first position and the longest protruding length in the third position. When the air duct plate 40 moves to the first position (as shown in fig. 4), the distance between the front end of the air duct plate 40 and the upper edge of the air outlet is the largest, the air outlet area is the largest, and the corresponding air outlet amount is also the largest. When the air duct plate 40 moves to the second position (as shown in fig. 5), the distance between the front end of the air duct plate 40 and the upper edge of the air outlet is moderate, and the air outlet area and the corresponding air outlet amount are moderate. When the air duct plate 40 moves to the third position (as shown in fig. 6), the distance between the front end of the air duct plate 40 and the upper edge of the air outlet is the smallest, and the air outlet area and the corresponding air outlet amount are also the smallest. In this embodiment, the air duct plate 40 can be switched between the three preset working positions, so as to change the extension length of the air duct plate 40, and adjust the size of the air outlet area, thereby adjusting the air outlet volume of the indoor unit.
When the user has just started the air conditioner and needs to cool/heat as quickly as possible, the duct board 40 is driven to the first position. The air deflector 30 rotates to be parallel to the extending direction of the air outlet duct 20, that is, the air deflector 30 rotates to be the same as the air guiding direction of the air outlet duct 20, as shown in fig. 4. At this time, the air outlet quantity is the largest, and the drainage quantity of the drainage plate 50 is also the largest, which is beneficial to the quick refrigeration/heating of the indoor unit of the air conditioner. When the indoor temperature reaches the temperature set by the user during cooling, the air duct plate 40 is driven to the second position, and the air deflector 30 rotates to be parallel to the extending direction of the air outlet duct 20, as shown in fig. 5. At the moment, cold air is upward, and the drained natural air is downward, so that the cold air and the natural air can be better mixed, and a user can feel cold air instead of cold air. When the user sleeps at night or the temperature is relatively low, the air duct plate 40 is driven to the third position, and the air deflector 30 rotates to be parallel to the extending direction of the air outlet duct 20, as shown in fig. 6. At the moment, the air outlet volume is minimum, the drainage volume is also minimum, and the user can always have a slight air blowing feeling, so that the air outlet mode cannot influence the rest of the user. When a user uses the air conditioner to heat in winter, the air duct plate 40 is driven to the first position, and the air deflector 30 rotates perpendicular to the extending direction of the air outlet duct 20, as shown in fig. 7. The air deflector 30 blocks the forward flow and directs the air flow vertically downward. Therefore, hot air can be directly blown to the ground, and in addition, as the flow guiding direction is vertical to the wind direction, almost no flow guiding air is mixed with the outlet air of the air outlet. The above-mentioned arrangement of the air duct plate 40 and the air guiding plate 30 can be realized by using a remote controller.
The wall-mounted air conditioner indoor unit of the embodiment can adjust the extension length of the air deflector 30 and the angle of the air deflector 30 according to different conditions, so that the air output and the air output mode of the indoor unit can be adjusted, and the requirements of users on air supply modes under different conditions are met. The air supply diversity of the indoor unit of the air conditioner is improved, and the user experience is improved.
