Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The embodiment of the application provides an air conditioner to solve the problems that an air deflector capable of realizing full closing of an air outlet in the existing air conditioner is high in cost and poor in air guiding effect, and the air conditioner is described below with reference to the accompanying drawings.

In the embodiment of the present application, as shown in fig. 1, the air conditioner 100 includes a body 11, an air duct 12 is disposed in the body 11, and an air outlet 13 is formed on a surface of the body 11 by the air duct 12, specifically, in this embodiment, the air conditioner 100 is a wall-mounted air conditioner, the body 11 is a wall-mounted indoor unit, and the body 11 generally includes a casing, a heat exchanger 14 installed in the casing, a wind wheel 15, an electric control box, an air duct component, and so on. The air duct 12 in the machine body 11 extends downwards and forwards from the wind wheel 15, and an air outlet 13 is formed between the front panel and the lower surface of the machine body 11, the air outlet 13 is located between the upper wall 1211 and the lower wall 1212 of the air duct 12, the shape of the air outlet is approximately rectangular, the length direction of the air outlet 13 is the length direction of the machine body 11, and the width direction of the air outlet 13 is the interval between the upper edge 131 and the lower edge 132. The upper edge 131 of the air outlet 13 is the edge of the upper wall 1211, and the lower edge 132 of the air outlet 13 is the lower edge 132 of the lower wall 1212. When the wind wheel 15 is started, air flow is blown into the air duct 12 from the wind wheel 15 and is blown out from the air outlet 13.

In order to realize opening and closing of the air outlet 13 and guiding of the air outlet, referring to fig. 1 and 5, the air conditioner 100 of the present application further includes an air deflector 20, the air deflector 20 includes an outer air deflector 21 and a plurality of layers of inner air deflectors 22, wherein the outer air deflector 21 is rotatably connected with the machine body 11, so that the air deflector 20 is switched among a closed state, an up-blowing state and a down-blowing state, and the plurality of layers of inner air deflectors 22 are fixedly arranged relative to the outer air deflector 21 so as to be capable of following the movement of the outer air deflector 21. Specifically, as shown in fig. 5, in the present embodiment, the inner air guide plate 22 is provided with two layers, and specifically includes a first inner air guide plate 221 and a second inner air guide plate 222, where the first inner air guide plate 221 is fixed on the second inner air guide plate 222, and the first inner air guide plate 221 is opposite to the second inner air guide plate 222 at intervals; the second inner air deflector 222 is fixed on the outer air deflector 21, and the second inner air deflector 222 is spaced apart from the outer air deflector 21, that is, the whole air deflector 20 is formed by sequentially connecting three layers of plates and mutually spacing. Of course, in practical application, other layers of the inner air guide plate 22 can be set according to the situation, for example, three layers, four layers, five layers and the like can be set for the inner air guide plate 22, and the specific layer number can be flexibly selected according to the requirement.

When the air guide plate 20 is mounted on the machine body 11, the outer air guide plate 21 is rotatably connected with the machine body 11, the multiple layers of inner air guide plates 22 rotate along with the outer air guide plate 21, and the whole air guide plate 20 can be switched among a closed state, an up-blowing state and a down-blowing state along with the rotation of the outer air guide plate 21.

When the air deflector 20 is in the closed state, the outer air deflector 21 is located at a position completely covering the air outlet 13, and the inner air deflector 22 is located in the air duct 12, specifically, when the air conditioner 100 is not in operation, the air deflector 20 can be switched to the closed state, and the outer air deflector 21 completely covers the air outlet 13 to fully close the air outlet 13, and the inner air deflector 22 is hidden in the air duct 12, so that the appearance of the air conditioner 100 is not affected.

In order to make the outer air deflector 21 completely cover the air outlet 13, referring to fig. 5, the outer shape of the outer air deflector 21 is also substantially rectangular, the length of the outer air deflector 21 is greater than the length of the air outlet 13, and the width of the outer air deflector 21 is also greater than the width of the air outlet 13; and when the outer air deflector 21 is rotatably connected to the machine body 11, the rotating shaft of the outer air deflector 21 may be disposed at one side in the width direction thereof, and then rotatably installed outside the air outlet 13 or rotated at the lower edge 132 of the air outlet 13, so that the outer air deflector 21 can be fully closed to the air outlet 13.

Alternatively, the connecting crank arm 23 may be used to rotatably connect the rotating shaft of the outer air deflector 21 to the inside of the machine body 11. For example, in this embodiment, the machine body 11 may be provided with a connection hole and a driving motor at a position near the lower edge 132 of the air outlet 13, as shown in fig. 5, the outer air deflector 21 is further provided with two connection crank arms 23, the two connection crank arms 23 are disposed at intervals along the length direction of the outer air deflector 21, and when assembled, the two connection crank arms 23 respectively extend into the machine body 11 and are connected with a preset connection hole and a driving motor on the machine body 11. It can be understood that by arranging the connecting crank arm 23 which is bent and extended, the outer air deflector 21 can directly move outwards to open the air outlet 13 under the pushing of the connecting crank arm 23, the outer air deflector 21 does not need to partially rotate into the air duct 12 when being opened, a gap is not needed to be reserved between the outer air deflector 21 and the edge of the air outlet 13, and then the air outlet 13 can be fully closed when the air outlet 13 is closed.

It should be noted that, in order to enable the air deflector 20 to be in the closed state, the multiple layers of inner air deflectors 22 can be hidden in the air duct 12, the size of the multiple layers of inner air deflectors 22 should be smaller than the opening size of the air outlet 13, and when other components such as soft air blades are arranged in the air duct 12, the multiple layers of inner air deflectors 22 also need to be designed in cooperation with the other components in the air duct 12, so that the multiple layers of inner air deflectors 22 can smoothly rotate into the air duct 12.

As shown in fig. 2 or fig. 3, when the air deflector 20 is in the up-blowing state, the outer air deflector 21 is located at a position where the air outlet 13 is opened, the inner air deflectors 22 are arranged at intervals along the height direction of the machine body 11, and the inner air deflectors 22 respectively guide the air flow to blow up or blow forward along the air duct wall 121 of the air duct 12. Specifically, when the air conditioner 100 is in the cooling mode, the air deflector 20 is switched to the up-blowing state, and the outer air deflector 21 is located at a position where the air outlet 13 is opened, and the specific opening angle thereof may be selected according to the actual situation. For example, as shown in fig. 2, when the outer air deflector 21 rotates to the first opening angle K1, the inner air deflector 22 is substantially parallel to the inner wall of the air duct 12, and the inner air deflector 22 is disposed along the height direction of the machine body 11, so as to respectively correspond to different positions in the air duct 12 or the air outlet 13, and part of the inner air deflector 22 extends out of the air outlet 13, so that the inner air deflector 22 can guide the air flow to blow forward along the inner wall of the air duct 12, and the part of the inner air deflector 22 extending out of the air outlet 13 corresponds to the extension of the air duct wall 121, so as to guide the cool air to a position further in front of the machine body 11. For another example, as shown in fig. 3, when the outer air deflector 21 rotates to the second opening angle K2 smaller than the first opening angle K1, the multi-layered inner air deflector 22 is deflected upward from a position substantially parallel to the duct wall 121, and thus cool air can be directed upward so that cool air is blown to a higher position in the room. Therefore, in a specific application, a specific opening angle of the outer air deflector 21 may be selected according to a practical situation, for example, when the indoor space is large and the cooling air is required to blow far, the outer air deflector 21 may be rotated to guide the air by the first opening angle K1; or the outer air deflector 21 may be rotated by the second opening angle K2 when the cool air is not required to be blown far.

It can be appreciated that when the air deflector 20 in the air conditioner 100 is in the upwind state, the inner air deflector 22 can respectively guide the air flows at different positions in the air duct 12 or the air outlet 13, so that the maximum distance between the air flows in the air duct 12 or the air outlet 13 and the air deflector 20 can be reduced, the air flows at each position can be more effectively guided, and the air guiding effect in the upwind guiding process can be improved.

In addition, in the present embodiment, as shown in fig. 4, when the air guide plate 20 is in the down-blowing state, the outer air guide plate 21 is located at a position where the air outlet 13 is opened, the inner air guide plates 22 are arranged at intervals in the width direction of the air outlet 13, and the inner air guide plates 22 extend to the lower side of the machine body 11, respectively. Specifically, when the air conditioner 100 is turned on to the heating mode, the air guide plate 20 may be switched to the down-blowing state, and at this time, the outer air guide plate 21 is also located at a position where the air outlet 13 is opened, and the opening angle of the outer air guide plate 21 is greater than the first opening angle K1 and the second opening angle K2, and for the specific opening angle, may be specifically selected based on the distance of the air supply on the basis that the multi-layer inner air guide plate 22 extends downward. For example, when the hot air is required to be directed downwards and farther forwards, the outer air deflector 21 can be rotated to a position where the opening angle is smaller and the multilayer inner air deflector 22 is ensured to be inclined downwards. Or when the hot air is required to be downwards and forwards closer, the outer air deflector 21 can be rotated to a position with a larger opening angle and ensuring that the multi-layer inner air deflector 22 is downwards inclined. In addition, in this embodiment, when the air deflector 20 is in the down-blowing state, since the inner air deflectors 22 are arranged at intervals along the width direction of the air outlet 13 and extend downward respectively, the air pressing area and the air pressing quantity of the air deflector 20 can be increased, so that more air outlet is pressed downward, and the air guiding effect in downward air guiding is improved.

It can be understood that, in the air conditioner 100 provided by the application, only one motor is required to drive the air deflector 20, so that the air deflector 20 can fully close the air outlet 13 when the air outlet 13 is closed, and on the basis that the air outlet 13 can be fully closed, a better air guiding effect is further realized, and the technical problems that the air deflector 20 capable of fully closing the air outlet 13 in the existing air conditioner 100 is high in cost and poor in air guiding effect are effectively solved.

Alternatively, in an embodiment, as shown in fig. 2, the updraft state includes a first updraft state, when the air deflector 20 is in the first updraft state, the multiple layers of the inner air deflector 22 are substantially parallel to the air duct wall 121, and at least a portion of the inner air deflector 22 extends out of the air outlet 13. Specifically, in the present embodiment, the duct wall 121 includes upper and lower walls 1211 and 1212 that are opposed to each other at intervals, and the multi-layered inner air deflector 22 includes a first inner air deflector 221 and a second inner air deflector 222; when the air deflector 20 is in the first updraft state, the first inner air deflector 221 is closer to the upper wall 1211 than the second inner air deflector 222, and the first inner air deflector 221 is substantially parallel to the upper wall 1211; the second inner air deflector 222 is substantially parallel to the lower wall 1212, and the second inner air deflector 222 extends out of the air outlet 13. It can be appreciated that, on the basis that the first inner air deflector 221 is parallel to the upper wall 1211 and the second inner air deflector 222 is parallel to the lower wall 1212, the second inner air deflector 222 extends out of the air outlet 13, so that the second inner air deflector 222 can be used as an extension of the lower wall 1212, and further, on the basis of ensuring lower air resistance, the air outlet is guided to a more distant position, the air supply distance is increased, and the air supply effect is improved. It will also be appreciated that because the upper wall 1211 is closer to the rotor 15 and the lower wall 1212 is further from the rotor 15, the airflow velocity near the upper wall 1211 will be faster and the airflow velocity near the lower wall 1212 will be less due to the centrifugal force of the rotor 15, and will also more easily sink directly after exiting the tuyere 13. Thus, by making the second inner air deflector 222 partially protruding out of the air outlet 13 closer to the lower wall 1212, the air flow flowing near the lower wall 1212 can be more effectively directed to a more distant position, improving the air guiding effect.

Of course, in practical applications, the inner air guide 22 may be provided in two or more layers, such as three layers, four layers, or the like, and in the case where the number of the inner air guide 22 is three or more, when the air guide 20 is in the first upwind state, one or several inner air guide 22 closer to the upper wall 1211 with respect to the lower wall 1212 may be extended parallel to the upper wall 1211, and one or several inner air guide 22 closer to the lower wall 1212 with respect to the upper wall 1211 may be extended parallel to the lower wall 1212.

Alternatively, in an embodiment, as shown in fig. 2, the lower wall 1212 extends in an arc shape, the second inner air deflector 222 extends in an arc shape, and the curvature of the second inner air deflector 222 is the same as the curvature of the lower wall 1212 (the curvature indicates the degree to which the curve deviates from a straight line). Specifically, in the present embodiment, the lower wall 1212 of the air duct 12 extends in an arc shape, and if the lower wall 1212 extends beyond the air outlet 13 along the original curvature, the lower wall 1212 gradually extends forward and upward of the machine body 11. Therefore, on the basis that the second inner air deflector 222 is disposed close to the lower wall 1212 and partially protrudes out of the air outlet 13, by making the curvature of the second inner air deflector 222 the same as that of the lower wall 1212, when the air deflector 20 is in the first upward blowing state, the second inner air deflector 222 can extend forward of the machine body 11 along the direction of the air flow near the air outlet 13, so that the air resistance can be reduced and the cool air can be guided to a more distant position.

Of course, as shown in fig. 2, the upper wall 1211 also gradually extends forward of the machine body 11 when approaching the air outlet 13, and when the air guide plate 20 is in the first upward blowing state, the front end of the first inner air guide plate 221 may gradually extend forward of the machine body 11 without affecting the closing of the air guide plate 20, and further, the cool air flowing along the first inner air guide plate 221 may be similarly guided further forward.

Further, in an embodiment, as shown in fig. 2, when the air deflector 20 is in the first upwind state, the length of the portion of the second inner air deflector 222 protruding out of the air outlet 13 is greater than the length of the portion of the second inner air deflector located in the air duct 12, so that the extension length of the second inner air deflector 222 outside the air outlet 13 can be increased, and further the air guiding distance and the air guiding effect can be improved.

Alternatively, in one embodiment, as shown in fig. 2, when the air deflector 20 is in the first upblowing state, the outer air deflector 21 is located at the first opening angle K1; as shown in fig. 3, the upward blowing state further includes a second upward blowing state, when the air deflector 20 is in the second upward blowing state, the outer air deflector 21 is located at a second opening angle K2, the second opening angle K2 is smaller than the first opening angle K1, and any position on the outer air deflector 21 is not higher than the lower edge 132 of the air outlet 13 in the height direction of the machine body 11. It will be appreciated that, because the second opening angle K2 is smaller than the first opening angle K1, when the air guide plate 20 is in the second upward blowing state, the multi-layered inner air guide plate 22 is rotated upward (specifically, the side of the inner air guide plate 22 closer to the outside of the machine body 11 is rotated upward) from a position substantially parallel to the air duct wall 121, so that the cool air can be guided upward, and the supply height of the cool air can be further increased. The difference between the first opening angle K1 and the second opening angle K2 may be 2 °, 3 °, 5 °, 8 °, 10 °, etc., and the specific angle difference may be selected according to actual needs. It will be further appreciated that when the air deflector 20 is in the second upwind state, the multiple layers of the inner air deflector 22 may respectively guide the cool air at different positions in the air duct 12 or the air outlet 13, for example, the first inner air deflector 221 guides the cool air near the upper wall 1211, and the second inner air deflector 222 guides the cool air near the lower wall 1212, so that it is avoided that a part of the air flow in the air duct 12 or the air outlet 13 cannot be effectively guided due to a distance from the air deflector.

In this embodiment, when the air deflector 20 is in the second upwind state, any position on the outer air deflector 21 is not higher than the lower edge 132 of the air outlet 13 in the height direction of the machine body 11, so that the situation that the wind resistance is large due to the shielding of the air outlet by the outer air deflector 21 can be avoided.

Alternatively, as described above, because upper wall 1211 of duct 12 is closer to wind wheel 15 and lower wall 1212 of duct 12 is farther from wind wheel 15, airflow velocity near lower wall 1212 is slower and is more prone to sinking directly after blowing out air outlet 13. Thus, in one embodiment, when the air deflection 20 is in the up-blown or down-blown condition, at least a portion of the inner air deflection 22 extends out of the air outlet 13 and is positioned closer to the inner air deflection 22 of the lower edge 132 of the air outlet 13 by a greater length extending out of the air outlet 13. That is, the closer to the lower wall 1212, the longer the inner air deflector 22 extends out of the air outlet 13, and the longer the inner air deflector 22 extends out of the air outlet 13, so that the air flow with a slower flow rate can be correspondingly guided and compensated, so that the cold air in each position in the air duct 12 or the air outlet 13 can be guided to a higher or more distant position, and the air guiding effect of the cold air is improved.

Alternatively, in an embodiment, as shown in fig. 4, when the air deflector 20 is in a down-blowing state, at least a part of the inner air deflector 22 extends from the air outlet 13 to the lower side of the machine body 11, for example, referring to fig. 4, the first inner air deflector 221 is located at the air outlet 13, and part of the first inner air deflector 221 is located in the air duct 12, and the other part extends out of the air outlet 13; and the second inner air deflector 222 extends obliquely downward and forward from the air outlet 13. It can be understood that the length of the air guide plate 20 outside the air outlet 13 can be increased, and the condition that hot air flows forward or upward at a higher position due to a shorter length of the air guide plate is avoided, so that more hot air can be blown to a lower indoor position, and the indoor heating efficiency is improved.

Optionally, in an embodiment, as shown in fig. 5, the outer air deflector 21 is further provided with a connecting crank arm 23, the outer air deflector 21 is rotatably connected with the machine body 11 through the connecting crank arm 23, and the inner air deflector 22 is fixedly connected with the connecting crank arm 23, that is, the outer air deflector 21 and the inner air deflector 22 are both connected with the connecting crank arm, so that not only the relative fixation between the inner air deflector 22 and the outer air deflector 21 can be realized, but also the structural strength of the whole air deflector 20 can be improved. When a plurality of connecting arms 23 are provided, one of the connecting arms 23 may be connected to the outer air guide plate 21 and the multi-layered inner air guide plate 22 at the same time, or the plurality of connecting arms 23 may be connected to the outer air guide plate 21 and the multi-layered inner air guide plate 22 at the same time. The specific connection mode can be selected according to the actual structural space, the processing difficulty and the like.

Optionally, in an embodiment, as shown in fig. 5, a plurality of first reinforcing plates 24 are further connected between the first inner air guiding plate 221 and the second inner air guiding plate 222, and the plurality of first reinforcing plates 24 are arranged at intervals along the length direction of the first inner air guiding plate 221; a plurality of second reinforcing plates 25 are also connected between the second inner air deflector 222 and the outer air deflector 21, and the plurality of second reinforcing plates 25 are arranged at intervals along the length direction of the second inner air deflector 222; in the length direction of the second inner air deflector 222, the plurality of first reinforcing plates 24 and the plurality of second reinforcing plates 25 are staggered, that is, the connection positions of each first reinforcing plate 24 and each second reinforcing plate 25 on the second inner air deflector 222 do not correspond to each other (or do not overlap with each other), one second reinforcing plate 25 corresponds to each adjacent two first reinforcing plates 24, and one first reinforcing plate 24 corresponds to each adjacent two second reinforcing plates 25. It will be appreciated that such an arrangement may better enhance the structural strength of the overall air deflection 20 by a smaller number of stiffening plates, making the structure of the air deflection 20 simpler and more stable.
