The invention provides an indoor unit of an air conditioner.
In the embodiment of the present invention, as shown in fig. 1 to 4, the air-conditioning indoor unit specifically relates to a wall-mounted air-conditioning indoor unit, and the air-conditioning indoor unit can be a single-cold machine or a cold-warm machine. The following description will be mainly given of an air conditioning indoor unit having both a cooling mode and a heating mode. The air conditioning indoor unit 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 opposite to each other. The first air guiding plate 120 is rotatably disposed on the casing 100 by a first pivot 121 disposed adjacent to the rear wall 112, and a wind shielding plate 122 is disposed on the windward side of the first air guiding plate 120 protruding toward the air duct 110. The second wind deflector 130 is rotatably disposed on the casing 100 at a second pivot 131 between the first pivot 121 and the front wall 111. The third air guiding plate 140 is rotatably disposed on the casing 100 by a third pivot 141 located between the first pivot 121 and the second pivot 131, two edges of the third air guiding plate 140 along the width direction are respectively suitable for forming an air outlet gap 150 with the wind shielding plate 122 and the second air guiding plate 130, and the third air guiding plate 140 and the wind shielding plate 122 are both provided with a plurality of air dispersing holes 160.
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 guiding plate 120 is rotatably mounted on the casing 100 through a first pivot 121, and it should be noted that the first pivot 121 may be a long axis extending along the length direction of the first air guiding plate 120, a short axis disposed at two opposite sides of the length direction of the first air guiding plate 120, or a rotating axis in other forms; in addition, the first pivot 121 may be disposed on opposite sides of the casing 100, and the first air guiding plate 120 is provided with a shaft hole adapted to the first pivot 121, as long as the first air guiding plate 120 can be rotatably connected to the casing 100. Similarly, the specific structure of the second pivot 131 and the third pivot 141 can refer to the first pivot 121, and is not limited in detail herein.
The wind shield 122 is protruded from the windward side of the first wind deflector 120, and the wind shield 122 may be fixed to the first wind deflector 120 by means of fastening, screwing, bonding, or the like, or may be integrally formed with the first wind deflector 120. The wind deflectors 122 and the third wind deflectors 140 are both provided with wind dissipating holes 160, and it can be understood that the wind dissipating holes 160 are disposed through the wind deflectors 122 and the third wind deflectors 140 along the thickness direction thereof, and the extending direction of the wind dissipating holes 160 may be perpendicular to the plate surfaces of the wind deflectors 122 and the third wind deflectors 140 or inclined at a certain angle. The shape of the air dispersing hole 160 may be circular, square, elongated, or a shaped hole, etc.
Two edges of the third air guiding plate 140 along the width direction thereof are respectively suitable for forming an air outlet gap 150 with the wind shielding plate 122 and the second air guiding plate 130. It can be understood that, the larger the air outlet gap 150 is, the larger the wind power output from the air outlet gap 150 is, so that the size of the air outlet gap 150 can be adjusted by the cooperation between the third wind deflector 140, the wind deflector 122 and the second wind deflector 130, so as to change the air outlet area, and further, the adjustment of the wind power output is realized. In order to achieve the no-wind effect well, the range of the air outlet gap 150 is preferably [3mm to 5mm ], and when the air outlet gap 150 is too small, for example, less than 3mm, the third air guiding plate 140 interferes with the wind deflector 122 and the second air guiding plate 130 during the rotation process; when the outlet gap 150 is too large, for example, greater than 5mm, the air speed of the airflow blown out from the outlet gap 150 is too large to achieve the no-wind-feeling effect, and the outlet gap 150 is preferably 4mm in practical applications.
Specifically, in the shutdown state, as shown in fig. 1, the third air guiding plate 140 is disposed in the air duct 110 of the casing 100, and an edge of the first air guiding plate 120 away from the first pivot 121 is connected to an edge of the second air guiding plate 130 close to the second pivot 131. The air outlet is closed under the matching of the first air deflector 120 and the second air deflector 130, 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.
When entering the no-wind-sensation mode, as shown in fig. 2, in the initial no-wind-sensation stage, the first wind deflector 120 and the second wind deflector 130 both rotate to positions substantially parallel to the horizontal plane, so that the airflow is horizontally led out. At this time, the third air guiding plate 140 is rotated to form a first air outlet gap 150 between an edge of the third air guiding plate 140 close to the third pivot 141 and an edge of the free end of the air shielding plate 122, at this time, a part of air flow is blown out through the air shielding plate 122, the air dispersing holes 160 on the third air guiding plate 140 and the first air outlet gap 150 between the air shielding plate 122 and the third air guiding plate 140, according to a turbulent flow effect, the wind power in the area is rapidly attenuated to form a non-wind-sensation area, and the other part of air flow is horizontally led out through air flow channels on the upper side and the lower side of the second air guiding plate 130, so that the non-wind-sensation effect is realized in the local area of the.
As shown in fig. 3, in the second stage of no wind sensation, the third wind deflector 140 is further rotated to form a second wind outlet gap 150 between the edge of the third wind deflector 140 far from the third pivot 141 and the edge of the second wind deflector 130 near the second pivot 131, at this time, a part of the airflow is blown out through the wind shielding plate 122 and the wind dispersing holes 160 on the third wind deflector 140 and the wind outlet gaps 150 on both sides of the third wind deflector 140 in the width direction, the wind power in this region is rapidly attenuated according to the turbulent effect to form a region without wind sensation, and another part of the airflow is horizontally led out from the airflow channel on the upper side of the second wind deflector 130, and through the cooperation between the third wind deflector 140 and the second wind deflector 130, the region without wind sensation is further expanded compared with the initial stage of no wind sensation, so that the smooth transition from the wind sensation to the no wind sensation can be effectively realized.
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 air conditioner indoor unit, when the air conditioner is switched to the no-wind-sensation mode, the first air deflector 120, the second air deflector 130 and the third air deflector 140 are matched with each other so that the wind power output can be gradually reduced, and therefore the smooth transition of the no-wind-sensation mode is achieved. Specifically, in the no-wind-sensation mode, the first wind deflector 120 and the second wind deflector 130 both rotate to positions substantially parallel to the horizontal plane to horizontally guide out the airflow, the third wind deflector 140 is rotatably disposed between the first wind deflector 120 and the second wind deflector 130, and is respectively matched with the wind deflector 122 and the second wind deflector 130 to form the wind outlet gap 150, and the gradual reduction of the wind output can be realized by adjusting the rotation position of the third wind deflector 140, so as to provide better no-wind-sensation experience for the user. The air conditioner indoor unit realizes the diversification of the no-wind-sense mode through the synergistic action among the air deflectors, meets the diversified requirements of users, and can realize the stable transition of the air conditioner when the air conditioner is switched to the no-wind-sense mode.
Further, referring to fig. 2, the second wind deflector 130 includes a wind guiding portion 132 and a tail wing 133 disposed on a side of the wind guiding portion 132 close to the second pivot 131, a cavity 134 is formed between the tail wing 133 and the wind guiding portion 132 in a stepped arrangement, and an end of the first wind deflector 120 away from the first pivot 121 can rotate into the cavity 134.
Specifically, in the embodiment, the second wind deflector 130 is designed to be similar to an airframe structure, the second wind deflector 130 includes a wind guiding portion 132 and a tail wing 133, and the tail wing 133 and the wind guiding portion 132 are arranged in a step shape to form a cavity 134. Thus, when the wind output needs to be further reduced, the front end of the first air deflector 120 can be rotated into the cavity 134 and abutted against the tail wing 133 of the second air deflector 130, so that the first air deflector 120 and the second air deflector 130 can be in sealing fit, and the influence of the leakage of the air flow from the gap between the first air deflector 120 and the second air deflector 130 on the non-wind effect is avoided.
Further, the width range between the side of the wind guiding portion 132 away from the second pivot 131 and the side of the wind guiding portion 132 close to the second pivot 131 is: [100mm, 300mm ]. In this embodiment, the second air deflector 130 is designed in an extension manner, so that when the air conditioner is in a cooling mode, the second air deflector 130 can function to extend the air duct 110, and the air flow is blown farther due to the coanda effect of the second air deflector 130 when passing through the air conditioner. In the heating mode, the airflow can be guided to the ground more under the action of the coanda effect, and the hot airflow rises from the ground due to low density, so that better heating experience can be provided for a user, and the foot warming function is achieved. The width of the air guiding portion 132 may be 100mm, 200mm, 300mm, etc., and the wider the air guiding portion 132, 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 conditioning indoor unit should be considered at the same time.
Further, as shown in fig. 6 and 7, the plurality of air diffusion holes 160 on the air deflector 122 are arranged in a matrix, and two rows of air diffusion holes 160 adjacent in the width direction of the air deflector 122 are arranged in a staggered manner in the length direction. Or/and the plurality of air dispersing holes 160 on the third air guiding plate 140 are arranged in a matrix, and two rows of air dispersing holes 160 adjacent to each other in the width direction of the third air guiding plate 140 are arranged in a staggered manner in the length direction.
In the embodiment, the wind shielding plates 122 and/or the wind dispersing holes 160 on the third wind guiding plate 140 are designed to be staggered, so that the air flows are disturbed after passing through the wind dispersing holes 160, interference is generated, the wind speed is further reduced, and the air flow is softer.
Further, referring to fig. 4 and 5, the indoor unit of the air conditioner further includes a fourth air guiding plate 170, the fourth air guiding plate 170 is rotatably disposed on the casing 100 by a fourth pivot 171 disposed adjacent to the front wall 111, and the fourth air guiding plate 170 is provided with a plurality of air dissipating holes 160.
In this embodiment, the fourth air deflector 170 is arranged to further adjust the wind output in the non-wind-sensing mode, so as to finally achieve the non-wind-sensing effect in all the regions. Specifically, on the basis of the second stage without wind sensation, the fourth air guiding plate 170 may be rotated to the air outlet flow surface of the air outlet channel located on the upper side of the second air guiding plate 130, so that the air flow can be blown out after passing through the air dispersing function of the air dispersing holes 160 on the fourth air guiding plate 170. When the fourth air deflector 170 rotates to a position substantially perpendicular to the second air deflector 130, the no-wind effect of the whole area is achieved, thereby giving the user the best no-wind experience.
Preferably, as shown in fig. 8, the plurality of air dispersing holes 160 on the fourth air deflector 170 are arranged in a matrix, and two rows of air dispersing holes 160 adjacent to each other in the width direction of the fourth air deflector 170 are arranged in a staggered manner in the length direction, 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 made softer.
It is understood that the wind speed in the middle region of the wind outlet of the wind channel 110 is generally greater than the wind speeds in the upper and lower regions, and the wind speed in the center of the wind dispersing holes 160 is related to the area of the wind dispersing holes 160. In order to maintain uniform wind force that is blown out after the wind scattering action via the wind scattering holes 160 of the wind deflector 122, the third wind deflector 140, and the fourth wind deflector 170, the diameter of the wind scattering hole 160 needs to be reduced at a position where the wind speed is high. Therefore, in the longitudinal cross section formed by the fourth air deflector 170, the third air deflector 140 and the wind deflector 122, the diameter of the air diffusing hole 160 in the middle area is preferably smaller than the diameters of the air diffusing holes 160 in the upper and lower side areas. In practical applications, it is preferable that the diameter of the air dispersing hole 160 of the third air guiding plate 140 is smaller than that of the air dispersing hole 160 of the fourth air guiding plate 170. The wind dispersing holes 160 on the wind shield 122 are at a certain angle with the airflow direction, and may be adjusted according to the specific angle in the actual situation, which is not limited herein, in order to make the wind outlet uniform.
Referring to fig. 4 again, the accommodating groove 113 is further concavely formed on the front wall 111, and the fourth air-guiding plate 170 is rotatably connected to the front wall 111 and can be accommodated in the accommodating groove 113. In the embodiment, by disposing the accommodating groove 113, the fourth air guiding plate 170 can be accommodated in the accommodating groove 113 in the cooling mode, or in the first stage without wind sensation and the second stage without wind sensation, so as to avoid generating resistance to the airflow and affecting the outlet air. The depth of the accommodating groove 113 may be set according to the thickness of the fourth air deflector 170, and preferably, when the fourth air deflector 170 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 deflector 170, or the fourth air deflector 170 is completely hidden in the accommodating groove 113.
Further, in order to prevent condensation generated during operation of the air conditioner, it is preferable that an insulating layer (not shown) is provided on the windward side of the first air deflection plate 120. Wherein, the heat-insulating layer can be made of inorganic fiber materials, such as mineral wool, rock wool, glass wool and the like; or organic heat insulating material, such as Polyethylene (PE) foam, Polystyrene (PS) foam, Polyurethane (PU) foam, etc. In addition, the insulating layer may be further disposed inside the first air guiding plate 120.
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 9, 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-sensation 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. 9, 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, the air conditioning indoor unit has a cooling mode, a heating mode and a no-wind mode. A plurality of buttons are arranged on a panel of the indoor unit of the air conditioner or a remote controller of the air conditioner, and different air outlet modes are selected through different buttons.
When the no-wind mode is selected, the first air deflector 120 and the second air deflector 130 are rotated to horizontally guide the air flow out. Specifically, as shown in fig. 2 and 3, the first air guiding plate 120 and the second air guiding plate 130 both rotate 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 third air guiding plate 140 rotates between the first air guiding plate 120 and the second air guiding plate 130 to adjust the air outlet gap 150 at the air outlet of the air duct 110, thereby achieving a smooth transition from the wind sensing mode to the non-wind sensing mode.
When the cooling mode is selected, the first air guiding plate 120 is rotated to a position substantially coinciding with the tangential extension plane of the rear wall surface 112 of the air duct 110, so that the air duct 110 can be effectively extended, and the air supply distance is further increased. In this mode, the second air guiding plate 130 may rotate to a position substantially parallel to the first air guiding plate 120, so as to further extend the air duct 110 and increase the air blowing distance. The second air deflector 130 can also be controlled to swing in the air outlet area of the air outlet so as to change the wind direction, thereby meeting 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 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.
Furthermore, the no-wind-sensation mode of the air-conditioning indoor unit at least comprises a no-wind-sensation first stage and a no-wind-sensation second stage. In the first stage without wind sensation, the first air guiding plate 120, the second air guiding plate 130 and the third air guiding plate 140 are rotated to form two air flow channels on the upper and lower sides of the second air guiding plate 130, and an air outlet gap 150 is formed between the edge of the third air guiding plate 140 close to the third pivot 141 and the free end of the wind screen 122. In the second stage without wind sensation, the third wind deflector 140 is rotated, and a wind outlet gap 150 is formed between an edge of the third wind deflector 140 far away from the third pivot 141 and an edge of the second wind deflector 130 close to the second pivot 131.
Specifically, in the present embodiment, the no-wind-sensation mode has two stages, in the first stage of no-wind-sensation, as shown in fig. 2, a part of the airflow is blown out through the wind-shielding plate 122 and the wind-dispersing holes 160 on the third wind-guiding plate 140, and the first wind-outlet gap 150 between the wind-shielding plate 122 and the third wind-guiding plate 140, and according to the turbulent effect, the wind in this region is rapidly attenuated to form a no-wind-sensation region, and the other part of the airflow is horizontally guided out through the airflow channels on the upper and lower sides of the second wind-guiding plate 130, so that the no-wind-sensation effect is achieved in the local region of the wind.
In the second stage without wind sensation, as shown in fig. 3, a part of the airflow is blown out through the wind shielding plate 122 and the wind dispersing holes 160 on the third wind deflector 140, and the wind outlet gaps 150 on both sides of the third wind deflector 140 in the width direction, and according to the turbulent effect, the wind in this region is rapidly attenuated to form a region without wind sensation, and another part of the airflow is horizontally led out from the airflow channel on the upper side of the second wind deflector 130, and through the cooperation between the third wind deflector 140 and the second wind deflector 130, the region without wind sensation is further enlarged compared with the initial stage without wind sensation, so that the smooth transition from wind sensation to no wind sensation can be effectively realized.
Furthermore, the indoor unit of the air conditioner includes a fourth air guiding plate 170, the fourth air guiding plate 170 is rotatably disposed on the casing 100 by a fourth pivot 171 disposed adjacent to the front wall 111, and the fourth air guiding plate 170 is provided with a plurality of air dissipating holes 160; the no-wind-sensation mode of the indoor unit of the air conditioner further comprises a no-wind-sensation third stage, and in the no-wind-sensation third stage, the fourth air deflector 170 is rotated to the air outlet circulation surface.
In the present embodiment, the fourth air guiding plate 170 is arranged to further adjust the wind output in the non-wind sensing mode, so that the non-wind sensing effect of all the regions is finally achieved. In the third stage of no wind sensation, as shown in fig. 4, when the fourth air guiding plate 170 rotates to a position substantially perpendicular to the second air guiding plate 130, the air flow can only be blown out from the air outlet holes 160 and the air outlet gaps 150 when reaching the air outlet, and the air flow at the air outlet holes and the air outlet gaps 150 is broken up by the turbulent action, so that the effect of no wind sensation in all regions is finally achieved, and the best experience of no wind sensation is provided for the user.
Furthermore, the air-conditioning indoor unit further comprises a detection control unit, wherein the detection control unit is used for detecting the indoor temperature or humidity and controlling the air-conditioning indoor unit to enter a corresponding no-wind-sensation stage according to a preset condition so as to provide optimal no-wind-sensation experience for a user. Wherein, the detection control unit can be a temperature or humidity sensor.
