With the improvement of people's living standards and quality, air conditioning has become an indispensable electrical equipment for home offices. The air conditioner panel is usually equipped with a temperature sensor to detect the ambient temperature. When the detected temperature reaches the preset temperature of the air conditioner, the air conditioner slows down or stops the air outlet.

In the related art, since there is a preset gap between the upper edge of the air guide plate in the air conditioner and the upper edge of the air duct outlet to ensure that the air guide plate extends and retracts smoothly, when the air guide plate sinks for heating, the air conditioner air duct The hot air emitted from the outlet will move upward along the air conditioning panel and be sucked into the air conditioner from the gap between the edge of the air guide plate and the upper edge of the air duct outlet. This will cause the ambient temperature detected by the temperature sensor to be too high and the air conditioner to misjudge. The air conditioner slows down or stops working.

Embodiments of the present disclosure provide an air conditioner for preventing air conditioning return air. By limiting the angle between the first outlet line and the connecting line, hot air cannot flow from the air guide plate during the air outlet process. The gap between the edge and the upper edge of the air duct outlet is sucked back into the air conditioner, thus preventing the air conditioner from slowing down or stopping work due to misjudgment by the temperature sensor.

An embodiment of the present disclosure provides an air conditioner that prevents air return from the air conditioner, as shown in Figure 1 .

Referring to FIG. 1 , the air conditioner includes: an air conditioning panel 60 and an air guide plate 50 .

Optionally, the air conditioning panel 60 is provided with an air outlet, and the upper side of the air outlet includes an upper outlet profile line 61, wherein the upper outlet profile line includes a first outlet line 611, a connecting line 612, and a third outlet line 612 connected in sequence from the outside to the inside. The two outlet lines 613, the first outlet line 611 and the connection line 612 intersect at the first connection point.

Among them, the air conditioning panel 60 is used to indirectly control the air conditioning operating mechanism to realize various functions of the air conditioning.

Optionally, the air guide plate 50 is provided at the air outlet, and the air guide plate 50 includes an upper edge and a lower edge.

The air guide plate 50 is an important component of the air conditioner and can guide the wind discharged by the air conditioner at different distances and angles, thereby improving the operating efficiency of the air conditioner.

Optionally, when the air guide plate 50 is opened downward, there is a first distance A between the upper edge and the first connection point, and the angle C between the first outlet line 611 and the connection line 612 is greater than or equal to The first preset angle.

By defining the angle C between the first outlet line 611 and the connecting line 612 , during the air discharge process, hot air cannot be sucked back into the air conditioner from the gap between the upper edge of the air guide plate 50 and the upper edge of the air duct outlet. , which can avoid the air conditioner slowing down or stopping working caused by misjudgment of the temperature sensor.

Optionally, the first preset angle is greater than or equal to 50.4°. For example, the first preset angle may be 60°, 70°, 80°, 90°, etc.

It can be seen from simulation calculations that when the first preset angle is greater than or equal to 50.4°, air leakage from the air conditioner cannot be sucked back into the air conditioner from the gap between the upper edge of the air guide plate 50 and the upper edge of the air duct outlet. When it is less than 50.3°, air leakage air from the air conditioner is sucked back into the air conditioner from the gap between the upper edge of the air guide plate 50 and the upper edge of the air duct outlet, affecting the detection results of the temperature sensor.

In a possible implementation, not shown in the figure, the first outlet line 611 is in an arc shape, and the connecting line 612 is in a straight shape.

The angle between the tangent line of the first outlet line 611 and the connecting line 612 is greater than or equal to the first preset angle.

It can be understood that the tangent line of the first outlet line 612 is the tangent line of the first outlet line 611 at the first connection point.

It can be understood that the tangent line of the connecting line 612 is the tangent line of the connecting line 612 at the first connection point.

Optionally, the connecting line 612 is in a concave arc shape.

In another possible implementation, referring to FIG. 1 , the connecting line 612 is straight-line, and the first outlet line 611 is straight-line.

The angle C between the first outlet line 611 and the connection line 612 is greater than or equal to the first preset angle.

There is a second distance D between the second connection point and the first connection point, and the second distance D is greater than or equal to the first distance A.

When the thickness B of the air guide plate 50 and the first distance A remain unchanged, there is a second distance D between the second connection point and the first connection point, and the second distance D is greater than or equal to the first distance A. This can fundamentally avoid the problem of air conditioners sucking back hot air.
