An air conditioning indoor unit according to an embodiment of the present invention is provided, and the air conditioning indoor unit according to the present invention will be specifically described with reference to fig. 1 to 22.
The indoor unit of the air conditioner of the present invention may be a wall-mounted indoor unit of an air conditioner, a floor air conditioner, or the like. The following description will be given taking a floor-type air conditioning indoor unit as an example, and a specific structure when the air conditioning indoor unit is other types will be easily conceived by those skilled in the art according to the disclosure of the present invention.
In an embodiment of the present invention, as shown in fig. 1 to 11, the indoor unit of an air conditioner includes:
the air conditioner comprises a shell 100, wherein the shell 100 is provided with an air inlet 101 and an air outlet 102, and an air duct is formed between the air inlet 101 and the air outlet 102;
the air guide frame 300 is installed on the casing 100, the air guide frame 300 is arranged corresponding to the air outlet 102, the air guide frame 300 penetrates through the front and the back to form an air guide opening communicated with the air duct, and a plurality of air guide strips 340 are arranged in the air guide opening; and the number of the first and second groups,
the first driving mechanism 400 is installed in the housing 100, the first driving mechanism 400 is connected to the air-guiding frame 300, and the first driving mechanism 400 is configured to drive the air-guiding frame 300 to move back and forth along the air outlet direction so as to extend out of the air outlet 102 or move back into the air outlet 102.
Specifically, the indoor unit of an air conditioner further includes a heat exchanger 700 and a fan 600, wherein the heat exchanger 700 is located between the air inlet 101 and the fan 600, and the fan 600 is used for driving air to enter the air duct from the air inlet 101, and after the air passes through the heat exchanger 700 for heat exchange, the air is blown out from the outlet air. A volute and a volute tongue are arranged between the fan 600 and the air outlet 102, and the volute tongue are surrounded to form an air outlet duct, so that air flow is concentrated and flows out from the air outlet 102, and the air outlet pressure is increased.
In this embodiment, the air outlet 102 is provided with an air guiding frame 300, and a rotatable air guiding strip 340 is disposed in the air guiding frame 300, so as to realize variation of the air supply angle. The air guide strip 340 is provided with a plurality of through holes 341, and the through holes 341 are communicated with the air duct, and it can be understood that the air guide strip 340 can open the air guide opening and can also close the air guide opening. When the air guide strip 340 closes the air guide opening, the air flow mainly flows out from the through hole 341 and does not directly blow to the user, thereby realizing the air supply without wind sense.
In the related art, when the air guide strip rotates to the state of closing the air guide opening from the state of opening the air guide opening, the air supply resistance is gradually increased, the air supply angle and the air supply range are gradually reduced, and until the air guide strip closes the air guide opening, namely the air conditioner is in a no-wind-sensation mode, the wind resistance is further increased, the air output is very small, and the refrigeration effect of the air conditioner is also linearly reduced. Although this no wind sense mode has realized that cold wind does not directly blow people's effect, because the air output is little, the air supply angle is little and the air supply distance is short for the difference is great with the local difference in temperature that is close to the air conditioner in the place far away from the air conditioner in the room, thereby makes cold and hot inhomogeneous, the comfort level is relatively poor in the room.
The invention provides an air-conditioning indoor unit, wherein a casing 100 of the air-conditioning indoor unit is provided with an air guide frame 300 and a first driving mechanism 400, the air guide frame 300 is arranged corresponding to an air outlet 102, a plurality of air guide strips 340 are arranged in the air guide frame 300, and the air guide frame 300 is driven by the first driving mechanism 400 to move back and forth along the air outlet direction, so that the air guide frame 300 extends out of the air outlet 102 or moves back into the air outlet 102. It can be understood that when the air conditioner is in the no-wind-sensation mode, the first driving mechanism 400 can push the wind guide frame 300 outwards, so that wind can be effectively discharged from two sides of the wind guide frame 300, the wind outlet angle can reach 180 degrees, the air supply range, the air supply distance and the air output under the no-wind-sensation mode are remarkably increased, and the uniformity and the comfort of the indoor temperature under the no-wind-sensation mode are improved. Therefore, the air conditioner indoor unit has the advantages of large air supply angle, long air supply distance, large air output and the like in a no-wind-sense mode.
When the air conditioner is in the no-wind mode, as shown in fig. 7, the first driving mechanism 400 may push the wind guide frame 300 outward. However, when the air conditioner is in other air blowing modes, as shown in fig. 6, the first driving mechanism 400 may also push the air guiding frame 300 outward to increase the air blowing angle and the air blowing range. Of course, when the air conditioner is in other air supply modes, as shown in fig. 3, the first driving mechanism 400 can also move the air guiding frame 300 back into the air outlet 102 again, so as to avoid the problems of sudden drop of indoor temperature and energy waste caused by excessive air output.
In this embodiment, as shown in fig. 6, when the air-guiding frame 300 is in a state of extending out of the air outlet 102, a portion of the air-guiding frame 300 in the air outlet direction is located in the air duct, and an air outlet channel is formed between the air-guiding frame 300 and a side wall of the air duct. Specifically, an air outlet channel is formed between the left side wall of the air guide frame 300 and the left side wall of the air duct, another air outlet channel is formed between the right side wall of the air guide frame 300 and the right side wall of the air duct, and the two air outlet channels are located on two sides of the air guide frame 300, so that air can be discharged from two sides of the air guide frame 300 after the first driving mechanism 400 drives the air guide frame 300 to be pushed outwards, and therefore the air supply angle, the air supply range and the air output of the indoor unit of the air conditioner are increased. Of course, in other embodiments, when the air-guiding frame 300 is in a state of extending out of the air outlet 102, the air-guiding frame 300 may be completely located outside the air duct in the air outlet direction, and air can be exhausted from two sides of the air-guiding frame 300.
In this embodiment, as shown in fig. 6 to 10, an air outlet frame 200 is disposed in the housing 100, the air outlet frame 200 is through from front to back to form the air outlet 102, and the air guiding frame 300 is mounted on the air outlet frame 200 in a manner of moving back and forth. Of course, in other embodiments, the air-out frame 200 may not be disposed in the housing 100, and the air-guiding frame 300 may be directly installed in the housing 100 in a front-back movement manner. However, in the technical solution of the present embodiment, the air outlet frame 200 is disposed in the casing 100, so that on one hand, the strength of the air outlet 102 of the casing 100 can be increased, and the casing 100 is prevented from being directly damaged when the air outlet 102 of the air guide frame 300 frequently moves; on the other hand, the first driving mechanism 400 and other structures are provided with mounting positions, so that the stability of the wind-guiding frame 300 during movement is improved.
In this embodiment, as shown in fig. 8 to 10, the air-out frame 200 includes an upper end plate 210, a lower end plate 220, and two first side plates 230 oppositely disposed to connect the upper end plate 210 and the lower end plate 220, the air-guiding frame 300 includes an upper end base 310, a second end plate, and two second side plates 330 oppositely disposed to connect the upper end base 310 and the lower end base 320, and when the air-guiding frame 300 is in a state of extending out of the air outlet 102, an air-out channel is formed between each first side plate 230 and the corresponding second side plate 330. Specifically, an air outlet channel is formed between the first side plate 230 and the second side plate 330 on the left side of the air guiding frame 300, and another air outlet channel is formed between the first side plate 230 and the second side plate 330 on the left side of the air guiding frame 300.
Further, the shape of the air guide frame 300 is matched with the shape of the air outlet frame 200. It can be understood that, since the air-guiding frame 300 needs to freely move relative to the air-guiding frame 300, by making the shapes of the two identical, on one hand, interference of the air-guiding frame 300 by the air-out frame 200 during the movement of the air-guiding frame 300 can be avoided, so that the air-guiding frame 300 does not move smoothly; on the other hand, when the air guiding frame 300 moves back into the air outlet frame 200, the gap between the air guiding frame and the air outlet frame is too large, so that part of the air flow is sent out from the air guiding opening and part of the air flow is filled into the gap to generate noise. Specifically, the cross-sectional shapes of the air guide frame 300 and the air outlet frame 200 may be trapezoidal, fan-shaped, trapezoid-like, or fan-like, and the invention does not limit the specific shapes of the air guide frame 300 and the air outlet frame 200.
In addition, the distance between the two first side plates 230 and the distance between the two second side plates 330 are gradually increased along the air outlet direction. That is, the air outlet 102 and the air guiding opening are both flared structures. Therefore, on one hand, the air guide frame 300 is easy to move out of the air outlet frame 200 and also easy to move into the air outlet frame 200; on the other hand, when the wind guide extends out of the wind outlet frame 200, the wind outlet gaps formed on both sides of the wind guide frame 300 are gradually increased along the wind outlet direction, so that the wind supply range and the wind output under the no-wind-sense mode can be expanded.
