The invention provides a wall-mounted air conditioner indoor unit 1, which generally comprises a casing 10, a heat exchanger 20, a heat exchange fan 30 and other components.
The casing 10 serves as a casing of the indoor unit 1, and protects the entire indoor unit 1, and at least one air inlet 12 and at least one air outlet 13 are further provided on the casing 10. In some embodiments, the air outlet 13 may be opened at the lower wall of the casing 10, so that it is opened downward.
The inside of the casing 10 may further define a heat exchanging space 16, the heat exchanging space 16 is used for installing a heat exchanger 20 and a heat exchanging fan 30, under the urging of the heat exchanging fan 30, indoor air may enter the heat exchanging space 16 from the air inlet 12 and exchange heat with the heat exchanger 20 to form an air supply flow, and finally the air supply flow may be discharged into a room from the air outlet 13 to adjust the indoor temperature.
Referring to fig. 2 to 4, in some embodiments, the wall-mounted indoor air conditioner unit 11 may further include a first baffle 40 and a second baffle 50.
The first flow guide plate 40 is provided at the air outlet 13 so as to be vertically translatable, and the first flow guide plate 40 may be further configured to be movable to a closed position for closing at least a partial area of the air outlet 13 or to a wind guide position below the air outlet 13 for guiding the flow of the supply air discharged from the air outlet 13 forward by using an upper surface thereof.
Referring to fig. 2 and 3, in the present embodiment, the first flow guiding plate 40 may be located below at least a partial area of the air outlet 13 and perform an up-and-down translational motion relative to the partial area. When the first diversion plate 40 moves upward to the air outlet 13 (i.e. the closed position), the air outlet 13 is closed. When the first flow guiding plate 40 moves downward from the closed position to the air guiding position, the first flow guiding plate 40 opens the partial area of the air outlet 13, and the air flow of the air supply formed in the housing 10 can be discharged from the partial area of the air outlet 13 and guided forward by the first flow guiding plate 40.
The second flow guiding plate 50 is movably disposed at the air outlet 13, and the second flow guiding plate 50 can move between the first flow guiding plate 40 and the rear edge of the air outlet 13 when the first flow guiding plate 40 is in the air guiding position, so as to guide the air flow discharged from the air outlet 13 to the first flow guiding plate 40.
Referring to fig. 2, in the embodiment, when the first air guiding plate 40 is located at the air guiding position, a certain gap exists between the first air guiding plate 40 and the air outlet 13, and in order to enable the air flow formed in the enclosure 10 to be guided by the first air guiding plate 40, the second air guiding plate 50 can move to a position between the first air guiding plate 40 and the rear edge of the air outlet 13 when the first air guiding plate 40 is located at the air guiding position, so that the second air guiding plate 50 can guide at least a part of the air flow to the rear end of the first air guiding plate 40, and finally the air flow is guided from the rear to the front from the first air guiding plate 40, so that the air flow is more converged, and the air supply adjustment is more efficient.
For example, when the indoor unit 1 is in the cooling mode, a user can adjust the first flow guide plate 40 and the second flow guide plate 50 to enable the first flow guide plate 40 to be located at the air guide position, and the second flow guide plate 50 is located between the first flow guide plate 40 and the rear edge of the air outlet 13, so that the cold air exhausted from the casing 10 is guided forward by the second flow guide plate 50 and the first flow guide plate 40 in sequence, and the cold air is blown flatly, thereby improving the wind feeling experience of the user, and improving the air supply comfort level.
As described in the background art, in order to adjust the air supply direction of the indoor unit of the air conditioner in the prior art, an air deflector capable of swinging up and down is generally arranged at an air outlet. However, this type of adjustment has certain disadvantages. Although the user can change the airflow direction by adjusting the angle of the air deflector, the adjustment means may bring other influences, for example, in the process of upward swinging of the air deflector, the area of the air deflector facing the air outlet is increasingly large, which results in reducing the air output when adjusting the air supply direction and influencing the temperature adjustment effect of the air conditioner.
In order to overcome the defects in the prior art, the wall-mounted air conditioner indoor unit 1 of the present embodiment uses two flow deflectors (i.e., the first flow deflector 40 and the second flow deflector 50) to cooperate with each other to adjust the direction of the supply air flow.
Specifically, when the first flow guide plate 40 is translated downward to the air guiding position, the second flow guide plate 50 moves between the first flow guide plate 40 and the rear edge of the air outlet 13 to guide the supply air flow discharged from the air outlet 13 to the first flow guide plate 40, and finally the supply air flow is guided forward by the first flow guide plate 40 with its upper surface.
Because first guide plate 40 is to when translation to wind-guiding position, first guide plate 40 is the downward translation, consequently, first guide plate 40 is leaving closed position and to wind-guiding position translation ground in-process and when being in wind-guiding position, and first guide plate 40 is in the outside of air outlet 13, and this can not exert an influence to the air-out area of air outlet 13, and then can not influence indoor set 1's the effect that adjusts the temperature.
Referring to fig. 2 to 4, in some embodiments, the second baffle 50 is rotatably mounted at the air outlet 13 and configured to be controllably rotated to guide the direction of the blowing air flow flowing out from between the first baffle 40 and the rear edge of the air outlet 13.
Since the first guide plate 40 needs to guide the flow of the supply air discharged from the air outlet 13 forward, and the second guide plate 50 can be moved between the first guide plate 40 and the rear edge of the air outlet 13 to guide the flow of the supply air discharged from the air outlet 13 to the first guide plate 40, the first guide plate 40 can be disposed at a position in front of the air outlet 13, and the second guide plate 50 can be disposed at a position in the rear of the air outlet 13 so as to guide the flow of the supply air discharged from the air outlet 13 to the first guide plate 40.
In some specific embodiments, one end of the second deflector 50 may be directly pivotally connected to the rear wall of the air outlet 13, so as to rotate the second deflector 50 around the air outlet 13.
Referring to fig. 2 to 4, in some other embodiments, the pivot axis of the second baffle 50 may also be disposed in front of the rear wall of the air outlet 13, and when the second baffle 50 rotates outwards, the rear end of the pivot axis rotates towards the inside of the air outlet 13, which is favorable for guiding the air flow out of the inside of the casing 10.
Referring to fig. 3, in some embodiments, the first baffle 40 and the second baffle 50 can also move to a position in tandem below the air outlet 13 to close the air outlet 13 together.
In the present embodiment, the sum of the widths of the first and second deflectors 40 and 50 may be configured to be equal to the width of the air outlet 13. That is, when the first flow guiding plate 40 is in the closed position, the second flow guiding plate 50 may move to make one end of the second flow guiding plate meet with the end of the first flow guiding plate 40, so as to realize that the first flow guiding plate 40 and the second flow guiding plate 50 respectively close the corresponding air outlets 13, and finally jointly close the whole air outlet 13.
Alternatively, the sum of the widths of the first baffle 40 and the second baffle 50 can be configured to be larger than the width of the air outlet 13, so that when the first baffle 40 is in the closed position, the opposite portions of the first baffle 40 and the second baffle 50 can overlap, and the above technical effects can also be achieved.
It is noted that when opposing portions of the first baffle 40 and the second baffle 50 overlap, the second baffle 50 is below the first baffle 40 to prevent the first baffle 40 from blocking movement of the second baffle 50.
Referring to fig. 5 to 7, fig. 5 is a schematic view illustrating a first air guide plate in an indoor unit according to a second embodiment of the present invention, where arrows show directions of air flows, fig. 6 is a cross-sectional view illustrating an air outlet closed by a second air guide plate in an indoor unit according to a second embodiment of the present invention, fig. 7 is a cross-sectional view illustrating a first air guide plate in a closed position in an indoor unit according to a second embodiment of the present invention, and arrows show directions of air flows.
Referring to fig. 6, in some other embodiments, the first baffle 40 and the second baffle 50 can also be moved to a position where the first baffle 40 is located above the second baffle 50 and the second baffle 50 closes the air outlet 13.
That is, in this embodiment, the width of the second baffle 50 may be configured to be at least equal to the width of the air outlet 13. The second flow guide plate 50 can rotatably open and close the air outlet 13, and wraps the first flow guide plate 40 in the air outlet 13 when the second flow guide plate 50 closes the position of the air outlet 13, so that the appearance of the indoor unit 1 is more neat and beautiful.
In addition, in the embodiment, the second flow guiding plate 50 not only has the function of closing the air outlet 13, but also guides the air flow discharged from the air outlet 13 to the first flow guiding plate 40, so that the first flow guiding plate 40 is located above the second flow guiding plate 50 to prevent the first flow guiding plate 40 from blocking the movement of the second flow guiding plate 50.
Referring to fig. 5, in the cooling mode, when a user needs to guide cold air forward, the second air deflector 50 may rotate to a preset position first, so as to avoid a translation path of the first air deflector 40, and then the first air deflector 40 may move from the closed position to the air guiding position, so that the second air deflector 50 is located between the first air deflector 40 and the rear edge of the air outlet 13 finally.
Referring to fig. 7, in the heating mode, when a user needs to guide hot air downward, since the first air guide plate 40 only closes part of the air outlet 13 and the second air guide plate 50 is located below the first air guide plate 40, the rotation of the second air guide plate is not affected by the first air guide plate 40, and at this time, the second air guide plate 50 can realize the function of a single air guide plate and rotate to a position extending downward, so as to guide the hot air downward.
It should be noted that the foregoing examples are only for describing the working principle of the first air guiding plate 40 and the second air guiding plate 50 of the present embodiment more clearly, and are not used to limit what temperature adjusting mode (heating or cooling) the indoor unit 1 is in when the first air guiding plate 40 and the second air guiding plate 50 are in what positions. The user can adjust the working positions of the first flow guide plate 40 and the second flow guide plate 50 at will according to the actual situation, for example, adjust the first flow guide plate 40 to the air guide position in the heating mode, and so on, which is not described herein again.
Referring to fig. 5, further, in a situation that the air outlet 13 is closed by the second air guiding plate 50, when the first air guiding plate 40 is in the air guiding position, the first air guiding plate 40 may be connected to the second air guiding plate 50 in an overlapping manner.
When the air outlet 13 is closed by the second air deflector 50, the width of the second air deflector 50 is at least equal to the width of the air outlet 13, and the first air deflector 40 is wrapped above the second air deflector 50, so that the rear end of the first air deflector 40 can be overlapped on the second air deflector 50 when the first air deflector 40 moves from the closed position to the air guiding position. Like this, when first guide plate 40 is in the wind-guiding position, there is not the clearance between first guide plate 40 and the second guide plate 50, and the air supply air current that leads through second guide plate 50 can all be guided first guide plate 40, has avoided partly air supply air current to spill between first guide plate 40 and the second guide plate 50, further makes the air supply more polymerization.
Referring to fig. 2 to 4, in some embodiments, the wall-mounted indoor unit 1 may further include a duct 60. The air duct 60 is disposed in the casing 10, and is used for guiding the air flow formed in the casing 10 to the air outlet 13, a section of the front wall 62 of the air duct 60 adjacent to the air outlet 13 is concave-curved, and a section of the rear wall 64 of the air duct 60 adjacent to the air outlet 13 is convex-curved.
As is well known, since the density of the hot air is relatively low compared to the density of the cold air, the air flow in the cooling mode lower duct 60 is lower, and the air flow in the heating mode lower duct 60 is higher.
In this embodiment, the air duct 60 may also be arranged to extend downward from back to front, so that the section of the front wall 62 of the air duct 60 adjacent to the air outlet 13 is arranged to be concave curved to function as a downward-pressing hot air; similarly, the section of the rear wall 64 of the air duct 60 adjacent to the air outlet 13 is configured as an outward convex curved surface, which can play a role of raising the cool air. In short, the shape of the air duct 60 in this embodiment is more favorable for guiding the supply air flow downward or upward, reducing the flow loss of hot air or cold air, and improving the efficiency of the indoor unit 1.
Referring to fig. 5 to fig. 7, further, a downward abutting surface 66 is provided between the front end of the air outlet 13 and the front wall 62 of the air duct 60, and the first baffle 40 abuts against a lower side of the abutting surface 66 when in the closed position.
