The invention provides an indoor unit of an air conditioner.
In an embodiment of the present invention, as shown in fig. 1 to 6, the indoor unit of an air conditioner includes a casing 100, a first air guiding plate 120, a second air guiding plate 130, and a third air guiding plate 140. An air duct 110 is formed in the housing 100, and an air outlet of the air duct 110 has a front wall 111 and a rear wall 112 that are oppositely arranged. The first air guiding plate 120 is rotatably disposed on the housing 100 with a first pivot 121 disposed adjacent to the rear wall 112. The second air guiding plate 130 is rotatably disposed on the windward side of the first air guiding plate 120 by the first pivot 121, and the second air guiding plate 130 is provided with an air dispersing hole 160. The third air guiding plate 140 is rotatably disposed on the casing 100 at a second pivot 141 between the first pivot 121 and the front wall 111.
In this embodiment, the casing 100 is used to form the overall appearance of the indoor unit of the air conditioner, the casing 100 includes a chassis, a face frame and a panel, an air inlet is provided on the casing 100, an air duct 110 is formed inside the casing 100, a heat exchanger assembly and a fan are further provided in the casing 100, and external air enters the casing 100 from the air inlet, and is sent out through the air outlet of the air duct 110 under the action of the fan after the heat exchange action of the heat exchanger. Specifically, the first air deflector 120 is rotatably mounted on the casing 100 by the first pivot 121, and the first pivot 121 may be a long axis extending along the length direction of the first air deflector 120, a short axis provided at two opposite sides of the length direction of the first air deflector 120, or another type of rotating shaft as long as the first air deflector 120 can be rotatably connected to the casing 100. The second air guiding plate 130 is rotatably disposed on the windward side of the first air guiding plate 120 by the first pivot 121, that is, the second air guiding plate 130 and the first air guiding plate 120 are coaxially disposed, that is, the first rotating shaft can realize independent rotation of the first air guiding plate 120 and the second air guiding plate 130. Similarly, the specific structure of the second pivot 141 can refer to the first pivot 121, and is not limited in detail. The second air guiding plate 130 is provided with an air dispersing hole 160, and it can be understood that the air dispersing hole 160 is disposed through the second air guiding plate 130 along the thickness direction thereof, and the extending direction of the air dispersing hole 160 may be perpendicular to the plate surface of the second air guiding plate 130 or inclined at a certain angle. The shape of the air dispersing hole 160 may be circular, square, elongated, or a shaped hole, etc.
In a shutdown state, as shown in fig. 1, the second air guiding plate 130 is disposed in the air duct 110 of the casing 100 and attached to the first air guiding plate 120, and an edge of the first air guiding plate 120 away from the first pivot 121 is connected to an edge of the third air guiding plate 140 close to the second pivot 141. The air outlet is closed under the matching of the first air deflector 120 and the third air deflector 140, so that on one hand, dust can be prevented from entering from the air outlet, and on the other hand, the whole air-conditioning indoor unit can be more beautiful.
In the cooling mode, as shown in fig. 2, the first air guiding plate 120 rotates to a position substantially coinciding with the tangential extension plane of the rear wall surface 112 of the air duct 110, which is equivalent to extending the air duct 110, and increasing the air supply distance. The second air guiding plate 130 rotates to the position attached to the first air guiding plate 120, so that the air output at the air outlet is not affected. It should be noted that the tangential extension plane is a virtual plane, which is a plane that is tangent to and extends along the edge of the rear wall 112 of the air duct 110. In the cooling mode, the first air guiding plate 120 is preferably overlapped with the tangential extending surface, and in practical applications, the first air guiding plate 120 may swing around the tangential extending surface by a certain angle, which is not limited in this respect. The third air guiding plate 140 can be rotated to a position substantially parallel to the first air guiding plate 120, so that the air duct 110 can be further extended, and the air blowing distance can be increased. Of course, the third air guiding plate 140 can also swing in the air outlet area of the air outlet to change the wind direction, thereby meeting different requirements of users.
In the heating mode, as shown in fig. 3, the first air guiding plate 120, the second air guiding plate 130 and the third air guiding plate 140 can be rotated to a position close to the vertical position to guide the air flow downward, so that the hot air flow can be blown to the ground to the maximum extent. Because the hot air flow density is lower and can rise upwards, better heating experience can be provided for users, and the foot warming function is achieved.
In the no-wind mode, as shown in fig. 4 to 6, the first wind deflector 120 and the third wind deflector 140 may cooperate with each other to horizontally guide the airflow out, so as to prevent the airflow from directly blowing the human body, and the rotational position of the second wind deflector 130 is adjusted, so that the airflow can be softened by the wind dispersing function of the wind dispersing holes 160 of the second wind deflector 130, thereby providing a better no-wind experience to the user.
According to the technical scheme, the first air deflector 120, the second air deflector 130 and the third air deflector 140 are arranged on the shell 100 of the indoor unit of the air conditioner, and the first air deflector 120, the second air deflector 130 and the third air deflector 140 are matched with each other, so that the air conditioner can achieve a better use effect in a refrigeration mode, a heating mode and a no-wind-sense mode, and the user experience is improved. In addition, the first air guiding plate 120 and the second air guiding plate 130 adopt a coaxial design, so that space optimization at the air outlet of the air duct 110 can be realized, and the air output at the air outlet is not influenced in the cooling and heating modes. Meanwhile, the movement structures of the first air deflector 120 and the second air deflector 130 are simplified, so that the air-conditioning indoor unit can be freely switched between the wind sensing mode and the non-wind sensing mode. The air conditioner indoor unit can effectively be compatible with refrigeration, heating and no-wind functions, and provides more mode selections for users, so that the experience comfort of the users can be effectively improved.
Further, the first pivot 121 is located on a side of the tangential extension of the rear wall 112 facing away from the front wall 111. In this embodiment, the first pivot 121 is disposed on the side of the tangential extension surface of the rear wall surface 112 away from the front wall surface 111, so that a staggered fit is formed between the rear side edge of the first air deflector 120 and the air outlet edge of the rear wall surface 112, thereby effectively reducing the gap between the first air deflector 120 and the air outlet of the air duct 110, preventing air leakage, and simultaneously ensuring that the first air deflector 120 can rotate to a position approximately coinciding with the tangential extension surface of the rear wall surface 112 to extend the air duct 110, and increasing the air supply distance.
Further, the distance between the two side edges of the third air guiding plate 140 along the width direction is: [100 mm-300 mm ]. In the embodiment, the third air guiding plate 140 is designed to be extended, and the width of the third air guiding plate 140 is wider than the widths of the first air guiding plate 120 and the second air guiding plate 130, so that the air flow is blown farther due to the coanda effect of the air flow when passing through the third air guiding plate 140 in the cooling mode. In the heating mode, the airflow can be guided to the ground more under the action of the coanda effect, so that the cooling and heating effects are effectively improved. The width of the third air guiding plate 140 may be 100mm, 200mm, 300mm, etc., and the wider the third air guiding plate 140, the better the effect of extending the air duct 110 is, but in practical application, the production cost and the specific size of the air conditioner indoor unit should be considered.
Further, in order to prevent condensation from being generated on the first air guide plate 120, an insulating layer 170 is provided on the windward side of the first air guide plate 120. Wherein, the heat-insulating layer 170 can be made of inorganic fiber material, such as mineral wool, rock wool, glass wool, etc.; or organic heat insulating material, such as Polyethylene (PE) foam, Polystyrene (PS) foam, Polyurethane (PU) foam, etc. In addition, the insulating layer 170 may be disposed inside the first air guiding plate 120.
Further, the indoor unit of an air conditioner further includes a fourth air deflector 150, the fourth air deflector 150 is rotatably disposed on the casing 100 by a third pivot 151 disposed adjacent to the front wall 111, and the fourth air deflector 150 is provided with an air dispersing hole 160.
In this embodiment, the fourth air guiding plate 150 is disposed to further improve the non-wind effect of the air conditioner. Specifically, referring to fig. 6, in the no-wind mode, the fourth air guiding plate 150 may be rotated to the air outlet flow surface of the air duct 110, so that the air flow can be blown out after passing through the wind dispersing function of the wind dispersing holes 160 on the fourth air guiding plate 150. By adjusting the position of the fourth air deflector 150, the wind output at the air outlet of the air duct 110 can be adjusted. Preferably, in the preset position, an edge of the fourth wind deflector 150 away from the third pivot 151 is adapted to be connected with an edge of the second wind deflector 130 away from the first pivot 121. That is, when the air duct rotates to the preset position, the second air guiding plate 130 and the fourth air guiding plate 150 are matched with each other to cover the whole air outlet, and the air flow in the air duct 110 can only be blown out from the air dissipating holes 160 on the second air guiding plate 130 and the fourth air guiding plate 150, so that the non-wind effect of the whole area at the air outlet is realized. It should be noted that, the second air guiding plate 130 and the fourth air guiding plate 150 described herein are connected, and it is not necessary that both plates are completely in sealing contact, for example, a certain air outlet gap may be left between the second air guiding plate 130 and the fourth air guiding plate 150, and as long as the air outlet gap is controlled within a certain range, the no-wind effect in the whole area is not affected.
Further, the plurality of air diffusion holes 160 on the second air guiding plate 130 are arranged in a matrix, and two rows of air diffusion holes 160 adjacent to each other in the width direction of the second air guiding plate 130 are staggered in the length direction. Or the plurality of air dissipation holes 160 on the fourth air guiding plate 150 are arranged in a matrix, and two rows of air dissipation holes 160 adjacent to each other in the width direction of the fourth air guiding plate 150 are arranged in a staggered manner in the length direction.
In the embodiment, the air-dispersing holes 160 on the second air deflector 130 or/and the fourth air deflector 150 are designed to be staggered, so that the air flows are disturbed after passing through the air-dispersing holes 160, interference is generated, the wind speed is further reduced, and the air flow is softer.
Referring to fig. 6, since the second air guiding plate 130 and the fourth air guiding plate 150 form a certain inclination angle with the horizontal direction when they are connected, preferably, the air dispersing hole 160 on the second air guiding plate 130 extends obliquely away from the first pivot 121 in the width direction of the second air guiding plate 130, and the air dispersing hole 160 on the fourth air guiding plate 150 extends obliquely away from the third pivot 151 in the width direction of the fourth air guiding plate 150. In this way, the airflow blown out by the air duct 110 can be guided out in a substantially horizontal direction through the obliquely arranged air dispersing holes 160.
Further, the front wall 111 is concavely provided with a receiving groove 113, and the fourth air guiding plate 150 is rotatably connected to the front wall 111 and can be received in the receiving groove 113. In the embodiment, by disposing the accommodating groove 113, the fourth air guiding plate 150 can be accommodated in the accommodating groove 113 in the cooling mode, so as to avoid generating resistance to the airflow and affecting the air outlet. The depth of the accommodating groove 113 may be set according to the thickness of the fourth air-guiding plate 150, and preferably, when the fourth air-guiding plate 150 rotates into the accommodating groove 113, the edge of the notch of the accommodating groove 113 is substantially flush with the outer surface of the fourth air-guiding plate 150, or the fourth air-guiding plate 150 is completely hidden in the accommodating groove 113.
The following describes in detail a control method of an air-conditioning indoor unit according to an embodiment of the present invention with reference to fig. 1 to 7, where the air-conditioning indoor unit is the air-conditioning indoor unit according to the above-mentioned embodiment of the present invention, the air-conditioning indoor unit includes a no-wind-sense mode, a cooling mode, and a heating mode, and a specific structure of the air-conditioning indoor unit refers to the above-mentioned embodiment, so that the method at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, and details are not repeated here.
As shown in fig. 7, the control method of an air conditioning indoor unit according to an embodiment of the present invention includes the steps of:
firstly, an air conditioner indoor unit is started, and an air outlet mode is selected. Specifically, a plurality of buttons are arranged on a panel of the air conditioner indoor unit or an air conditioner remote controller, and different air outlet modes are selected through different buttons.
When the cooling mode is selected, the first air deflector 120 and the second air deflector 130 are rotated to guide the air flow out along the tangential extension plane of the rear wall surface 112. Specifically, as shown in fig. 2, the first air deflector 120 is rotated to a position substantially coinciding with the tangential extension plane of the rear wall surface 112 of the air duct 110, and at this time, the rear end of the first air deflector 120 is in staggered fit with the rear wall surface 112 of the air duct 110, which is equivalent to extending the air duct 110, so that the pressure of the air inlet can be effectively increased, and the air supply distance is further increased. And the second air guiding plate 130 rotates to a position substantially attached to the first air guiding plate 120, so that the air output at the air outlet of the air duct 110 is not affected. Preferably, in this mode, the third air deflector 140 rotates to a position substantially parallel to the first air deflector 120, so as to further extend the air duct 110 and increase the air blowing distance. Of course, the third air guiding plate 140 can also be controlled to swing in the air outlet area of the air outlet to change the wind direction, so as to meet different requirements of users.
When the heating mode is selected, the first air deflector 120, the second air deflector 130 and the third air deflector 140 are rotated to guide the air flow downward. Specifically, as shown in fig. 3, the first air deflector 120, the second air deflector 130 and the third air deflector 140 are controlled to rotate to a position close to the vertical position to guide the air flow downwards, so that the hot air flow can be blown to the ground to the maximum extent. Because the hot air flow density is lower and can rise upwards, better heating experience can be provided for users, and the foot warming function is achieved.
When the no-wind mode is selected, the first air deflector 120, the second air deflector 130 and the third air deflector 140 are rotated to horizontally guide the air flow out. Specifically, as shown in fig. 4 to 6, the first air guiding plate 120 and the third air guiding plate 140 are both rotated to positions substantially parallel to the horizontal plane, so that the air flow can be led out horizontally, thereby preventing the air flow from directly blowing the human body, and effectively reducing the wind experience of the user. The second air guiding plate 130 can rotate in the air duct 110 to have different rotating positions, so as to adjust the wind output in a no-wind-sense state, and further improve the no-wind-sense experience.
Further, the no-wind-sensation mode of the air conditioning indoor unit at least includes a no-wind-sensation first stage, in which the first air deflector 120, the second air deflector 130 and the third air deflector 140 are rotated, and two airflow channels extending in the horizontal direction are formed at the upper and lower sides of the third air deflector 140.
Specifically, as shown in fig. 4, when the no-wind-sensation button is selected, the indoor unit of the air conditioner automatically enters the first no-wind-sensation stage, and at this time, the first air deflector 120 and the third air deflector 140 both rotate to positions substantially parallel to the horizontal direction, so that two air flow channels are formed on the upper side and the lower side of the third air deflector 140, and the air flow can be horizontally led out. The second air guiding plate 130 rotates to a position substantially attached to the first air guiding plate 120, without affecting the air output at the air outlet of the air duct 110. In this stage, the air current can be avoided directly blowing the human body and experience in order to reduce user's wind sense, can also guarantee simultaneously that the air current has certain ability output, makes indoor temperature can satisfy user's demand. Certainly, the no-wind-sensation mode can also comprise other multiple stages, the indoor unit of the air conditioner can detect the indoor temperature or humidity through the detection control unit and then automatically select to enter the corresponding no-wind-sensation stage under the control of the detection control unit, so that the optimal no-wind-sensation experience is provided for the user. Wherein, the detection control unit can be a temperature or humidity sensor.
Further, the no-wind-sensation mode of the indoor unit of the air conditioner further includes a no-wind-sensation second stage, in which the second wind deflector 130 is rotated to form a preset angle between the second wind deflector 130 and the first wind deflector 120.
Specifically, as shown in fig. 5, in the second stage without wind sensation, the second wind guide plate 130 rotates away from the first wind guide plate 120, so that a preset angle is formed between the second wind guide plate 130 and the first wind guide plate 120. In this way, the airflow can be softened by the wind dispersing function of the wind dispersing holes 160 of the second wind deflector 130, so as to give a better non-wind feeling experience to the user. While enabling a reduction in wind output on the basis of the non-wind-sensitive first stage.
Further, the indoor unit of an air conditioner further includes a fourth air deflector 150, the fourth air deflector 150 is rotatably disposed on the casing 100 by a third pivot 151 disposed adjacent to the front wall 111, and the fourth air deflector 150 is provided with an air dispersing hole 160. The no-wind-sensation mode of the indoor unit of the air conditioner further includes a no-wind-sensation third stage, and in the no-wind-sensation third stage, the fourth wind deflector 150 is rotated, so that the edge of the fourth wind deflector 150, which is far away from the third pivot 151, is connected with the edge of the second wind deflector 130, which is far away from the first pivot 121.
Specifically, as shown in fig. 6, in the third stage without wind sensation, the fourth wind deflector 150 is rotated, so that the edge of the fourth wind deflector 150 away from the third pivot 151 is connected to the edge of the second wind deflector 130 away from the first pivot 121. Therefore, the second air deflector 130 and the fourth air deflector 150 are matched with each other to cover the whole air outlet, and the air flow in the air duct 110 can only be blown out from the air dispersing holes 160 on the second air deflector 130 and the fourth air deflector 150, so that the wind output in the no-wind-sensation mode is further reduced, and the no-wind-sensation effect of the whole area is finally realized.
