Detailed Description

In the wall-mounted air conditioner 010 of the related art, a gap exists between the front panel 110 and the inner middle frame 200, and a lower edge of the front panel 110 forms a part of an edge (often an upper edge) of the air outlet 130. When the air conditioner is air-conditioned in the cooling mode, the air flow may sweep the inside of the front panel 110, resulting in a decrease in the temperature of the front panel 110. The indoor hot air is cooled after contacting the front panel 110, and moisture therein is condensed, thereby generating condensation in the front panel 110. To avoid condensation, a blocking member may be provided between the front panel 110 and the blower 400 to block the air flow to avoid the inside of the front panel 110 from being purged with cold air. However, if the structure of the blocking component is unreasonable, the flow field of the air outlet airflow is possibly poor, vortex and turbulent flow are easily generated, the air quantity loss is large, even abnormal sound is caused, and the use experience of a user is further affected.

In order to improve at least one of the disadvantages of the related art, the embodiment of the present utility model provides a wall-mounted air conditioner 010, which improves the condensation problem of the front panel 110 by arranging the wind deflector 300 and designing the shape of the wind deflector 300, and ensures that the flow field of the air outlet flow is reasonable and the air outlet effect is better.

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Fig. 1 is a schematic diagram of a wall-mounted air conditioner 010 according to an embodiment of the present utility model; fig. 2 is a cross-sectional view of a wall-mounted air conditioner 010 according to an embodiment of the present utility model. As shown in fig. 1 and 2, the wall-mounted air conditioner 010 includes a housing 100, and a blower 400 and a center 200 (not shown) provided in the housing 100. The housing 100 forms an air outlet 130 and an air inlet 120, and under the driving of the fan 400, air flows from the air inlet 120 into the housing 100 and is mainly sent out from the air outlet 130. The fan 400 is mounted on the middle frame 200, an air outlet duct 140 is formed between the fan 400 and the air outlet 130, and air flow sent by the fan 400 is sent out from the air outlet 130 through the air outlet duct 140. In this embodiment, the fan 400 is a cross-flow fan 400.

The up-down relationship in fig. 2 corresponds to the up-down relationship when the wall-mounted air conditioner 010 is in use. In this embodiment, the housing 100 includes a front panel 110, and a lower edge of the front panel 110 forms an upper edge of the air outlet 130. There is a certain gap between the inner side of the front panel 110 and the middle frame 200, and it is understood that when too much cool air enters into the gap, the temperature of the front panel 110 may be reduced to be low, thereby causing dew to be easily generated on the outer surface of the front panel 110. For this purpose, the air deflector 300 is disposed in the housing 100 of the present embodiment, and the air deflector 300 is disposed between the front panel 110 and the outlet of the fan 400. Specifically, the wall-mounted air conditioner 010 includes an air guiding frame 210, and the air guiding frame 210 is fixedly disposed in the casing 100 and can be fixedly connected to the middle frame 200 or fixedly connected to an inner wall of the casing 100. The wind deflector 300 is connected to the wind guiding frame 210.

Further, in the present embodiment, the wind deflector 300 is rotatably connected to the wind guiding frame 210, and the wall-mounted air conditioner 010 further includes a wind shielding driving member for driving the wind deflector 300 to rotate relative to the wind guiding frame 210. The wind deflector 300 has a first state and a second state, the first state differing from the second state in that the wind deflector 300 is rotated to a different position. Accordingly, the wind deflector 300 can be driven to switch between the first state and the second state by the wind deflector drive.

When the wind deflector 300 is in the first state (as shown in fig. 2), the wind deflector 300 can block the airflow in the air outlet duct 140 from blowing toward the inner side of the front panel 110. It should be appreciated that the blocking of the wind deflector 300 may be a blocking of a portion of the airflow or a blocking of the entire airflow. When the air flow is blocked, it is not easy to blow directly to the inner side of the front panel 110 so that the temperature of the front panel 110 is not too low, and then the hot air is not easy to generate condensation after contacting the front panel 110.

With the wind deflector 300 in the second state, the wind deflector 300 unblocks the airflow in the outlet air duct 140 such that at least a portion of the airflow can be purged up to the inside of the front panel 110.

Specifically, in the present embodiment, the front panel 110 is provided with the vent hole 111, and a gap air duct 112 communicating with the vent hole 111 is formed on the inner side of the front panel 110, and the gap air duct 112 and the vent hole 111 may be used for air outlet. With the air deflector 300 in the second state, at least a portion of the airflow can be blown up into the gap duct 112 and then sent to the outside of the front panel 110 through the ventilation hole 111. In this embodiment, the front panel 110 is provided with a plurality of ventilation holes 111, and the airflow sent out through the ventilation holes 111 is more dispersed than the airflow sent out from the air outlet 130, so that the "direct blowing feeling" is weakened, and the comfort level of the user is improved.

In the case that the wind deflector 300 is in the first state, the wind deflector 300 is located between the air outlet duct 140 and the gap duct 112 to block the air flow of the air outlet duct 140 from entering the gap duct 112. Since the wind deflector 300 is configured to be controllably rotatable and switchable between the first state and the second state, a plurality of wind outlet schemes can be provided for a user, thereby better satisfying the user's needs.

Further, the wall-mounted air conditioner 010 of the embodiment further includes a damper (not shown in the figure) capable of closing or opening the air outlet 130. In addition, the damper also has a function of guiding the air-out direction when the air-out is performed using the air outlet 130. In this embodiment, when the air guide door completely closes the air outlet 130, the air baffle 300 can be switched to the second state, so that all the air flows are sent out from the air vent 111 on the front panel 110 through the gap air duct 112. It should be appreciated that both the supply of air from the air outlet 130 and the supply of air from the vent 111 may be used in combination.

The wind deflector 300 includes an arc-shaped section 302 and a straight-line section 301 connected in sequence in the width direction thereof, and when the wind deflector 300 is in the first state, the arc-shaped section 302 is located upstream of the straight-line section 301 in the flow direction of the air outlet duct 140, and the inner arc side of the arc-shaped section 302 faces the air outlet duct 140.

In this embodiment, the arc-shaped section 302 of the wind deflector 300 in the first state is located at the upstream, the straight-line section 301 is located at the downstream, the air flow sent out by the fan 400 firstly makes a buffer transition on the inner arc surface of the arc-shaped section 302, is guided by the arc surface of the arc-shaped section 302 to change the air direction, and is further guided to the straight-line section 301, and is blown to the air outlet 130 along the straight-line section 301, and the whole process of the air flow is smoother when flowing through the wind deflector 300, so that the air outlet flow field is more reasonable, turbulence and vortex are not easy to occur, excessive air loss and noise are caused, and the air outlet effect is better.

Alternatively, the width ratio of straight segment 301 to arcuate segment 302 is 0.5 to 0.6. In fig. 4, the width of straight segment 301 is denoted by W1, and the width of arcuate segment 302 is denoted by W2. Alternatively, the straight segment 301 has a width of 13-14 mm and the arcuate segment 302 has a width of 22-25 mm. When the straight line segment 301 and the arc segment 302 adopt the width values and the width ratios, the blocking and guiding effects on the air flow are better.

In this embodiment, two posts 311 are provided on the wind deflector 300, and the two posts 311 are engaged with hinge holes on the two mounting portions 211. The outer arc side of the arc-shaped section 302 is convexly provided with a connecting portion 310, a plug 311 is disposed at the connecting portion 310, and the plug 311 extends along the length direction of the wind deflector 300. In alternative embodiments, the number of posts 311 and hinge holes may be further increased or decreased as desired.

In this embodiment, the wind deflector 300 is provided with an avoidance gap, and the avoidance gap is used for avoiding the mounting portion 211 in the rotation process of the wind deflector 300. During the rotation, the wind deflector 300 may interfere with the mounting portion 211, so that an avoidance gap is provided to avoid interference between the wind deflector 300 and the mounting portion 211. In this embodiment, the number of avoidance notches is identical to the number of the insert posts 311.

Referring to fig. 2, in the present embodiment, in the first state of the wind deflector 300, a virtual extension of an end of the straight line segment 301 away from the curved segment 302 (a dotted line portion of the front end of the wind deflector 300 in fig. 2) passes below the lower edge of the front panel 110. By this arrangement, the air flow is better ensured to flow to the air outlet 130 guided by the straight line section 301, and the possibility of blowing directly to the inside of the front panel 110 is reduced.

In alternative embodiments of the present utility model, the wind deflector 300 may have only the first state, in other words, the wind deflector 300 may be fixedly connected to the wind guiding frame 210, not rotatably connected.
