It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other.

Referring to fig. 1, an embodiment of the present disclosure provides an air conditioner including an air outlet duct 100 and a baffle 200. The air outlet pipeline 100 is provided with a turning section 110, one end of the air outlet pipeline is provided with an air inlet 101, the other end of the air outlet pipeline is provided with an air outlet 102, the included angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is a poor angle, and the guide plate 200 is arranged in the turning section 110 and has the same bending direction as the turning section 110.

By adopting the air conditioner provided by the embodiment of the disclosure, as the guide plate 200 is arranged in the turning section 110, the guide plate 200 provides guidance for the air flow passing through the turning section 110 and avoids disturbance between the air flows at two sides of the guide plate 200, thereby reducing air quantity loss under the condition of changing the air direction of the air flow and improving the performance of the air conditioner. And the bending direction of the deflector 200 is the same as the bending direction of the turning section 110, so that the airflow flowing direction in the turning section 110 is consistent with the airflow guiding direction of the deflector 200, and the airflow flows more smoothly.

It is understood that inferior angles refer to angles greater than 0 ° and less than 180 °, with right, acute and obtuse angles collectively referred to as inferior angles.

Specifically, the included angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is 90 °. Like this, the air conditioner is sent into indoor with cold wind through the air-out wind channel, because the air inlet direction of air intake 101 is 90 with the contained angle of the air-out direction of air outlet 102, air outlet 102 can blow in indoor with cold wind downwards for the space cooling speed of indoor low department is faster, improves user's experience.

Specifically, the included angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is 60 °. Like this, the air conditioner is sent into indoor with cold wind through the air-out wind channel, because the contained angle of the air inlet direction of air intake 101 and the air-out direction of air outlet 102 is 60, and air outlet 102 can blow in indoor with cold wind towards the direction of indoor low department for the space cooling speed of indoor low department is faster, improves user's experience.

Optionally, the turn section 110 is a circular arc shaped pipe structure. In this way, the turning section 110 has a circular arc pipeline structure, so that the bending transition is gentle, the air quantity loss of the air flow in the process of passing through the turning section 110 is reduced, and the performance of the air conditioner is improved.

As shown in connection with fig. 2, the outlet duct 100 may optionally further comprise an inlet section 120 and an outlet section 130. The air inlet section 120 is communicated with one end of the turning section 110, and the other end is provided with an air inlet 101; one end of the air outlet section 130 is communicated with the other end of the turning section 110, and the other end is provided with an air outlet 102. In this way, the cold air in the air conditioner enters the air inlet section 120 from the air inlet 101, then enters the turning section 110 from the air inlet section 120, and the cold air flow is turned in the turning section 110 and is blown into a room from the air outlet section 130 and the air outlet 102.

Optionally, the air inlet 101 has a larger excess flow than the air outlet 102. Like this, the excessive flow of air intake 101 is greater than the excessive flow of air outlet 102, and the air current is in the in-process of blowing into indoor through air outlet 102, because air outlet 102 is less relatively, the air current of air outlet 102 department can be compressed for the temperature of air current further reduces, improves the cooling effect indoor.

Optionally, the baffle 200 divides the interior of the turn section 110 into a first wind cavity 111 and a second wind cavity 112, wherein the first wind cavity 111 has a first inlet 113 and a first outlet 114. Thus, in the case of the airflow passing through the turning section 110, the airflow is split into two airflows by the baffle 200, wherein one airflow passes through the first air chamber 111, and the other airflow passes through the second air chamber 112. Mutual disturbance between the air flow in the first air cavity 111 and the air flow in the second air cavity 112 is avoided, so that air quantity loss under the condition that the air direction of the air flow is changed is reduced, and the performance of the air conditioner is improved.

Optionally, the excess flow of the first inlet 113 is less than or equal to sixty three percent of the excess flow of the air intake section 120 and greater than or equal to forty three percent of the excess flow of the air intake section 120. Thus, in the case that the excessive flow rate of the first air inlet 113 is greater than sixty percent of the excessive flow rate of the air inlet section 120, the excessive flow rate of the first air inlet 113 may excessively occupy the space of the second air chamber 112. In the case that the excessive flow rate of the first air inlet 113 is less than forty three percent of the excessive flow rate of the air inlet section 120, the excessive flow rate of the first air inlet 113 is too small, so that the air flow rate difference between the first air chamber 111 and the second air chamber 112 is too large, and the separation and flow guiding effects of the flow guiding plate 200 are reduced. Therefore, the over-flow of the first air inlet 113 is less than or equal to sixty three percent of the over-flow of the air inlet 120, and the range of the over-flow of the air inlet 120 is more reasonable, so that the difference between the air flow in the first air chamber 111 and the air flow in the second air chamber 112 is reduced, and the separation and flow guiding effects of the flow guiding plate 200 are improved.

Specifically, the excess flow of the first inlet 113 is equal to fifty-three percent of the excess flow of the inlet section 120. In this way, the difference in the air flow rates in the first air chamber 111 and the second air chamber 112 is reduced, and the separation and flow guiding effects of the baffle 200 are improved.

Optionally, the first outlet chamber 114 has an excess flow rate of less than or equal to fifty percent of the excess flow rate of the air intake section 120 and greater than or equal to thirty percent of the excess flow rate of the air intake section 120. Thus, if the excess flow of the first outlet chamber 114 is greater than fifty percent of the excess flow of the inlet end, the space of the second air chamber 112 is excessively occupied. In the case that the excessive flow rate of the first outlet cavity 114 is less than thirty percent of the excessive flow rate of the air inlet section 120, the excessive flow rate of the first outlet cavity 114 is too small, so that the airflow velocity of the first air cavity 111 is too slow. Therefore, the over-flow of the first outlet 114 is less than or equal to fifty percent of the over-flow of the air inlet 120, and the range of more than or equal to thirty percent of the over-flow of the air inlet 120 is reasonable, so that the air flow velocity of the first air chamber 111 is relatively high without excessively occupying the space of the second air chamber 112.

Specifically, the first outlet chamber 114 has an excess flow rate equal to forty percent of the excess flow rate of the inlet section 120. In this way, the airflow rate of the first air chamber 111 is relatively high without excessively encroaching on the space of the second air chamber 112.

As shown in fig. 3, alternatively, the baffle 200 has a windward end 210 and a leeward end 220, where the windward direction of the windward end 210 forms a bad angle with the leeward direction of the leeward end 220. In this way, the included angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is inferior angle, and the bending direction of the deflector 200 and the bending section 110 is the same, so that the deflector 200 can better separate the air flow in the bending section 110, reduce the air volume loss under the condition of changing the air direction of the air flow, and improve the performance of the air conditioner.

Specifically, the angle between the windward direction of windward end 210 and the leeward direction of leeward end 220 is 85 °.

Specifically, the angle between the windward direction of windward end 210 and the leeward direction of leeward end 220 is 55 °.

Specifically, the distance between the windward end 210 and the air intake end in the horizontal direction is greater than or equal to thirty-six percent of the diameter of the air intake 101, and less than or equal to fifty-six percent of the diameter of the air intake 101.

Specifically, the distance between the windward end 210 and the air intake end in the horizontal direction is equal to forty-six percent of the diameter of the air intake 101.

Specifically, the length of the air outlet duct 100 in the horizontal direction is greater than or equal to ninety percent of the diameter of the air inlet 101, and less than or equal to one hundred and ten percent of the diameter of the air inlet 101.

Specifically, the length of the air outlet duct 100 in the horizontal direction is equal to the diameter of the air inlet 101.

In some experimental examples, in order to more intuitively show the effect of reducing the air flow direction and changing the air quantity loss of the air flow guide plate 200, as shown in fig. 4 and 5, experimental example 1, in which the air guide plate 200 is not arranged in the air outlet pipeline 100, and experimental example 2, in which the air guide plate 200 is arranged in the air outlet pipeline 100, were subjected to flow field simulation.

As can be seen from fig. 4 and 5, the lighter the color in the air outlet duct 100, the higher the static pressure and the larger the wind resistance, and the larger the air volume loss, respectively, the static pressure of 25Pa is applied to the air inlets 101 of the experimental examples 1 and 2. The high static pressure area of the turning section 110 in example 1 is significantly greater than that of example 2 in the turning section 110, which means that the windage resistance of the turning section 110 in example 1 is greater, while the baffle 200 in example 2 reduces the windage resistance of the turning section 110, and the air flow is smoother and the air loss is smaller.

Optionally, a plurality of baffles 200 are disposed within the turn section 110. In this way, by arranging the plurality of guide plates 200 in the turning section 110 and dividing and guiding the air flow in the turning section 110 by the plurality of guide plates 200, the mutual interference between the air flows at two sides of each guide plate 200 is avoided, thereby reducing the air quantity loss under the condition of changing the air direction of the air flow and improving the performance of the air conditioner. And the bending direction of each guide plate 200 is the same as the bending direction of the turning section 110, so that the airflow flowing direction in the turning section 110 is consistent with the airflow guiding flowing direction of the guide plates 200, and the airflow flows more smoothly.

Specifically, two baffles 200 are disposed within the turn section 110. In this way, by arranging two guide plates 200 in the turning section 110 and dividing and guiding the air flow in the turning section 110 by the two guide plates 200, the mutual interference between the air flows at two sides of each guide plate 200 is avoided, thereby reducing the air quantity loss under the condition of changing the air direction of the air flow and improving the performance of the air conditioner. And the bending direction of each guide plate 200 is the same as that of the turning section 110, so that the resistance in the air flow flowing process is reduced, the air flow flowing direction in the turning section 110 is consistent with the air flow guiding flowing direction of the guide plates 200, and the air flow flowing is smoother.

As shown in fig. 6, the air conditioner may optionally further include a fixing plate 121. The fixed plate 121 is disposed in the air inlet section 120, and one end of the fixed plate 121 is fixedly connected with the windward end 210 of the deflector 200. In this way, the air flow in the air inlet section 120 is divided in advance by the fixing plate 121, and the two divided air flows directly flow into the first air chamber 111 and the second air chamber 112.

Optionally, a plurality of fixing plates 121 are provided, and each fixing plate 121 is fixedly connected to the windward end 210 of a corresponding one of the deflectors 200. In this way, the air flow in the air intake section 210 is divided in advance by the fixing plate 121.

Specifically, the fixing plate 121 is provided with two.

Alternatively, the baffle 200 is an arcuate plate-like structure. In this way, the curved transition of the baffle 200 with the arc-shaped plate-shaped structure is gentle, the baffle 200 provides guidance for the air flow in the turning section 110, the air quantity loss of the air flow in the process of passing through the turning section 110 is reduced, and the performance of the air conditioner is improved.

Optionally, the air conditioner further includes an indoor unit 300. The air outlet duct 100 is disposed in the indoor unit 300. In this way, the air outlet pipe 100 is disposed in the indoor unit 300, so as to reduce the risk that the air outlet pipe 100 protrudes out of the outer surface of the indoor unit 300, and reduce the risk that the air outlet pipe 100 collides with other objects during the installation process of the indoor unit 300. And the heat exchange between the air outlet pipeline 100 and the outside can be reduced, and the temperature loss of the air flow in the air outlet pipeline 100 can be reduced.

Optionally, the air conditioner further comprises an air inlet pipe 400. The air inlet pipe 400 is disposed in the indoor unit 300, and the flow area of the air inlet end of the air inlet pipe 400 is larger than the flow area of the air outlet end. Thus, the indoor air enters the indoor unit 300 through the air inlet duct 400, exchanges heat, and is then blown into the room through the air outlet duct 100. Because the flow area of the air inlet end of the air inlet pipeline 400 is larger than that of the air outlet end, the air inlet range of the air inlet end is relatively larger, and more air can be better sucked.

Optionally, the air inlet end of the air inlet duct 400 is provided with a guide plate 410. In this way, the air flow is guided to flow into the air intake duct 400 by the provision of the guide plate 410.

As shown in connection with fig. 7, the guide plate 410 may alternatively include a vertical plate 411 and an inclined plate 412. The upper end of the vertical plate 411 is fixedly coupled to the lower end of the inclined plate 412. Thus, the air flows into the air inlet duct 400 through the vertical plate 411, and the air flow changes direction by the inclined plate 412. Also, due to the blocking of the inclined plate 412, part of dust in the air can be blocked, and the amount of dust sucked into the air intake duct 400 can be reduced. In the case of power-off of the air conditioner, dust in the air inlet duct 400 falls down on the inclined plate 412 and slides down out of the air conditioner.

Optionally, the air inlet end of the air inlet pipe 400 is provided with a plurality of vertical plates 411 and a plurality of inclined plates 412, and each vertical plate 411 is provided with one inclined plate 412. Thus, the air flows into the air inlet duct 400 through between the plurality of vertical plates 411, and the air flow changes direction by the inclined plates 412. Also, due to the blocking of the inclined plate 412, part of dust in the air can be blocked, and the amount of dust sucked into the air intake duct 400 can be reduced. In the case of the power-off of the air conditioner, dust in the air intake duct 400 falls down on the inclined plates 412 and falls down between the vertical plates 411.

As shown in fig. 8, specifically, a heat exchange chamber 310 is provided inside the indoor unit 300, and the air outlet pipe 100 and the air inlet pipe 400 are both in communication with the heat exchange chamber 310. In this way, the air flow enters the heat exchange chamber 310 through the air inlet pipeline 400 for heat exchange, and is discharged through the air outlet pipeline 100.

Optionally, an evaporator 320 is disposed in the heat exchange chamber 310, and the distance between the evaporator 320 and the air outlet pipeline 100 is greater than the distance between the evaporator 320 and the air inlet pipeline 400. In this way, the temperature of the air flow after heat exchange by the evaporator 320 is relatively low, and the air flow with relatively low temperature can be quickly blown into a room due to the relatively short distance between the evaporator 320 and the air outlet pipeline 100, so that the indoor cooling effect is improved.

Alternatively, the evaporator 320 is disposed obliquely in the heat exchange chamber 310. In this way, the evaporator 320 is inclined, so that the length of the evaporator 320 which can be arranged is relatively long, and the heat exchange area of the evaporator 320 is increased, thereby improving the heat exchange effect.

Optionally, a fan 330 is disposed in the heat exchange chamber 310, and a distance between the fan 330 and the air inlet pipe 400 is greater than a distance between the fan 330 and the air outlet pipe 100. In this way, in the case that the blower 330 operates to suck indoor air, since the interval between the blower 330 and the air inlet duct 400 is relatively small, the distance to suck air is relatively short, and the effect of the blower 330 sucking air through the air inlet duct 400 is improved.

The above description and the drawings illustrate embodiments of the disclosure sufficiently to enable those skilled in the art to practice them. Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others.
