The invention provides an air conditioner indoor unit and an air conditioner comprising the same, wherein the air conditioner indoor unit can realize no-wind-sense air outlet so as to improve the comfort level of a user using the air conditioner indoor unit.
Referring to fig. 1 and 2, in a first embodiment of the indoor unit of an air conditioner according to the present invention, the indoor unit of the air conditioner includes a housing 100, a first wind deflector 10 and two second wind deflectors 20; the shell 100 is provided with an air outlet duct 1a positioned at the inner side of the shell and a first air outlet communicated with the air outlet duct 1a, and the upper side and the lower side of the first air outlet of the shell 100 are respectively provided with a second air outlet communicated with the air outlet duct 1 a; the first wind deflector 10 is rotatably installed at the first air outlet to rotatably open or cover the first air outlet; and two second wind shields 20, each second wind shield 20 is correspondingly installed at one second air outlet, and at least one of the first wind shield 10 and the two second wind shields 20 is consistently provided with a wind dispersing hole.
Specifically, the casing 100 includes a rear casing and a face casing 110 disposed on the front side of the rear casing, where the rear casing and the face casing 110 enclose to form a cavity in which the heat exchanger 1 and the air duct assembly of the indoor unit of the air conditioner are installed; the top of the face shell 110 is provided with an air inlet 111, the first air outlet is arranged at the lower end of the front panel of the face shell 110, and the second air outlet is arranged at the lower side of the first air outlet, namely the bottom of the face shell 110; the heat exchanger 1 is adjacent to the air inlet 111; the air duct assembly comprises a wind wheel 2, wherein the wind wheel 2 is arranged on one side of the heat exchanger 1, which is away from the air inlet 111, and is positioned at the inner end of the air outlet air duct 1 a. When the indoor unit of the air conditioner works, the wind wheel 2 drives air flow to enter from the air inlet 111, then the air flow is sent to the first air outlet or the second air outlet through the air outlet air duct 1a after heat exchange of the heat exchanger 1, and finally the air flow is blown into a room.
The first wind deflector 10 is rotatably connected with the housing 100, specifically may be a pivotal connection or a hinged connection, so as to open or close the first air outlet by rotating the first wind deflector 10.
The mode of installing the second wind deflector 20 at the second air outlet is not limited, and specifically should be selected according to whether the second wind deflector 20 is penetrated with a wind-dispersing hole, if the second wind deflector 20 is not penetrated with a hole plate with a wind-dispersing hole, the second wind deflector 20 may be in snap connection or pivot connection with the housing 100; if the second wind deflector 20 is a solid plate without through holes, the second wind deflector 20 is preferably rotatably connected to the housing 100.
According to the technical scheme, the second air outlets are additionally formed in the upper side and the lower side of the first air outlet of the shell 100 respectively, and the second wind shield 20 is arranged corresponding to each second air outlet, so that two paths of air outlets are additionally formed on the basis of the conventional one path of air outlet of the indoor unit of the air conditioner, three paths of air outlets are formed, and therefore, the air flow can be prevented from being directly blown to a user by switching the air outlet air paths; and a wind dispersing hole is consistently formed in one of the first wind deflector 10 or the second wind deflector 20, so that when the indoor unit of the air conditioner works, the air flow blown out from the air outlet air duct 1a is dispersed out through the wind dispersing hole on the first wind deflector 10 or the second wind deflector 20, in the process, the wind speed of the air flow is reduced, and the air flow is dispersed and becomes soft, so that the wind speed of the air flow blown into the room is smaller and softer, and the user cannot feel the flow of the air flow, thereby achieving the wind-sensing-free air outlet effect. Compared with the conventional air conditioner indoor unit for directly blowing air indoors, the air conditioner indoor unit provided by the invention can realize that the air conditioner indoor unit can flow out in a multi-channel mode, and at least one path of air is air-out without sense, so that the air speed is reduced, the air-out without sense is realized, and the comfort level of a user using the air conditioner indoor unit is improved.
Referring to fig. 2, in the present embodiment, only the first baffle plate is perforated with air-diffusing holes, and the second wind deflector 20 is rotatably connected with the housing 100. That is, the first baffle is an orifice plate through which the air-diffusing holes are formed, and the two second wind-shielding plates 20 are solid plates not through which the air-diffusing holes are formed. Specifically, the first air outlet is located at the lower end of the front panel of the face shell 110, and one of the second air outlets is located on the front panel of the face shell 110 and above the first air outlet; the other second air outlet is disposed at the bottom of the face shell 110.
As shown in fig. 2-a, when the indoor unit of the air conditioner is not in operation, the first wind deflector 10 and the second wind deflector 20 are both in a closed state. As shown in fig. 2-B, when the indoor unit of the air conditioner starts to cool at the initial stage, the first wind deflector 10 may be opened, so that the airflow is directly blown out from the first air outlet, and normal air outlet is achieved, so that the indoor space is rapidly cooled.
By changing the opening and closing states of the first wind deflector 10 and the two second wind deflectors 20, the indoor unit of the air conditioner can realize a plurality of wind-sensing-free wind-out modes, wherein:
In this mode, as shown in fig. 3-a, the first wind deflector 1010 and the two second wind deflectors 20 are in a covering state, and the air flow of the indoor unit of the air conditioner blows from the air outlet channel to the indoor through the air outlet holes on the first wind deflector 10, so as to realize the air outlet without wind sensation at the first air outlet.
As shown in fig. 3-B, in this mode, the first wind deflector 10 and the second wind deflector 20 located at the upper side of the first wind outlet are opened, the second wind deflector 20 located at the lower side of the first wind outlet is closed, the air flow of the indoor unit of the air conditioner is divided into two air flows, and the first air flow is directly blown out from the first wind outlet, so as to realize rapid refrigeration; the second air flow is directly blown out upwards in an inclined way through the second air outlet and then naturally drops in a spraying way, and in the process, the air speed is reduced, so that the second air outlet is free from wind sensing.
As shown in fig. 3-C, in this mode, the first wind deflector 10 and the second wind deflector 20 located at the lower side of the first wind outlet are opened, the second wind deflector 20 located at the upper side of the first wind outlet is closed, the air flow of the indoor unit of the air conditioner is divided into two air flows, and the first air flow is directly blown out from the first wind outlet, so as to realize rapid cooling or heating; the second air flow is blown out downwards directly through the second air outlet, is deflected to be blown out by the wall-mounted of the indoor unit of the air conditioner under the action of the second wind shield 20 positioned at the lower side of the first air outlet, and cannot be blown to a user directly, so that the second air outlet is free from wind.
In this mode, as shown in fig. 3-D, both the first wind deflector 10 and the second wind deflector 20 are open. The air flow of the air conditioner indoor unit is divided into three air flows, and a first air flow is directly blown out from the first air outlet, so that rapid refrigeration or heating is realized; the second air flow is blown out upwards through one second air outlet, and the third air flow is blown out downwards through the other second air outlet, so that the second air flow cannot be directly blown to a user, on one hand, the two air flows disperse the air outlet of the indoor unit of the air conditioner, so that the air flow of the first air outlet is reduced, and the air flow which is not easy to feel by the user is enabled to flow so as to achieve the effect of no wind sensation; on the other hand, the two airflows enlarge the air supply range of the indoor unit of the air conditioner, and are beneficial to quickly realizing the large-range refrigeration or heating of the indoor.
As for the second wind deflector 20 and the housing 100, for example, two ends of the second wind deflector 20 are provided with rotating shafts, and the housing 100 is provided with shaft holes for inserting the rotating shafts. The pivotal connection position of the two second wind shields 20 and the housing 100 has different influences on the air supply distance and the air outlet deflection direction of the second air outlet. As shown in fig. 3-B, for the second wind deflector 20 located on the upper side of the first wind outlet, there are two pivoting positions with the housing 100100:
In one mode, the side portion of the second wind deflector 20 near the first wind outlet is pivotally connected to the housing 100. When the second wind guard 20 is opened, the second wind guard 20 lengthens the air supply distance of the corresponding second air outlet, and the air blown out from the second air outlet flows to a higher position and then naturally subsides, so that the air is not easy to blow to a user, and the user cannot feel the air;
In a second mode, the side portion of the second wind deflector 20 away from the first wind outlet is pivotally connected to the housing 100. In this way, the air flow blown out from the second air outlet is stopped by the inner plate surface of the second wind deflector 20 and does not blow to the outer surface of the face shell 110, so as to avoid the condensed water generated on the outer surface of the face shell 110.
In addition, as shown in fig. 3-C, for the pivotal connection position located at the lower side of the first air outlet, it is preferable that the front side portion of the second air deflector 20 is pivotally connected to the housing 100. When the second wind guard 20 is opened, the second wind guard 20 extends the air supply distance of the corresponding second air outlet, and the air flow blown out from the second air outlet is deflected to be blown out from the wall of the indoor unit of the air conditioner, so that the air flow cannot be blown onto the user, and the user cannot feel the air flow.
Referring to fig. 2, in order to adjust the air flow through the second air outlet, the indoor unit of the air conditioner has a volute 120 for forming an air outlet duct 1a, the volute 120 is provided with an air passage communicating the air outlet duct 1a with the second air outlet, and the spoiler 30 is rotatably installed in the air passage.
Specifically, the volute 120 is located in the housing 100, the volute 120 is provided with an upper volute and a lower volute matched with the upper volute to form an air outlet duct 1a, the upper volute is adjacent to the second air outlet above, and the lower volute is adjacent to the second air outlet below; the upper volute and the lower volute are respectively provided with an air passage communicated with the air outlet air duct 1a and the corresponding second air outlet, and a spoiler 30 arranged in each air passage. The side portion of each spoiler 30, which is closer to the first air outlet, is pivoted to the volute 120, and the opening of the air passage is adjusted by controlling the rotation angle of the spoiler 30, so as to control the air flow through the corresponding second air outlet. For example, when the spoiler 30 rotates until the plate surface thereof is consistent with the air outlet direction of the air passing channel, the air flow through the second air outlet is larger; when the spoiler 30 rotates to an angle between the plate surface and the air outlet direction of the air passage, the air flow passing through the second air outlet is secondary; when the spoiler 30 rotates to a position where the plate surface thereof is perpendicular to the air outlet direction of the air passage, the air flow through the second air outlet is smaller.
As for the manner of controlling the rotation of the spoiler 30, it may be manually controlled, or may be controlled by a motor drive.
Referring to fig. 2 again, considering that condensed water is easily generated on the rear wall surface of the scroll case 120 adjacent to the air passage when the air flow passes through the air passage, it is preferable that an insulation layer 3 is provided on the inner wall surface of the air passage, and the insulation layer 3 is made of insulation material, which may be insulation cotton or insulation foam.
Referring to fig. 2, in order to enhance the windless air outlet effect of the indoor unit of the air conditioner, the spoiler 30 is provided with a plurality of spoiler holes penetrating through the surface thereof, and the spoiler holes are used for primarily disturbing the air flow so as to reduce the wind speed thereof and to be softer. When the spoiler 30 rotates to the point that the plate surface thereof is perpendicular to the air outlet direction of the air outlet channel, the air outlet effect without wind sense of the first air outlet can be enhanced. When the spoiler 30 rotates to a position where the plate surface thereof is perpendicular to the air outlet direction of the air passing channel, the windless air outlet effect of the second air outlet can be enhanced.
Considering that if the air flow disturbing holes on the spoiler 30 are opposite to the air flow dispersing holes on the second baffle in the air outlet direction of the air passage, the air flow passing through the spoiler 30 directly passes through the air dispersing holes on the second wind deflector 20 along the air outlet direction, so that the disturbance of the spoiler 30 to the air flow is not obvious, and the air flow speed cannot be well reduced.
Therefore, in this embodiment, the air-diffusing holes on the second baffle and the air-diffusing holes on the spoiler 30 are staggered in the air-out direction of the air-passing channel. Thus, after the airflow passes through the spoiler 30, the airflow is buffered in the air passage and can be diffused out from the air diffusing holes on the second wind shield 20, so that the wind speed of the airflow is further reduced, and the windless air outlet effect of the second air outlet is enhanced.
Referring also to fig. 2, a baffle located in the wind passage is rotatably installed in the scroll case 120. By adjusting the angle through which the spoiler 30 rotates, the direction of the airflow in the air outlet channel can be adjusted to deviate towards the first air outlet or the second air outlet, so that the airflow through the first air outlet and the second air outlet can be controlled.
Referring to fig. 4 and 5, in a second embodiment of the indoor unit of an air conditioner, the difference between the first embodiment and the second embodiment is that the first wind deflector 10 and the two second wind deflectors 20 are respectively provided with a wind dispersing hole. Thus, by changing the opening and closing states of the first wind deflector 10 and the two second wind deflectors 20, one-way wind-sensing-free wind outlet of the air conditioner indoor unit can be realized.
As shown in fig. 5-B, only when the first wind deflector 10 is opened, the wind resistance of the first wind outlet is small, and the two second wind outlets are blocked by the second wind deflector 20 and the flow-around plate, so that the wind resistance is large, and most of the air flow of the indoor unit of the air conditioner is blown into the room from the first wind outlet, thereby realizing the normal wind outlet mode.
As shown in fig. 6, in the air conditioning indoor unit of the present embodiment, at least four air-out modes without air sense can be implemented, unlike the air-out modes without air sense in the first embodiment, when the airflow of the air conditioning indoor unit flows to any one of the second air outlets, the airflow can pass through the second wind shield 20 through which the air-dispersing holes are formed, and the wind speed of the airflow is reduced, so that the air-out without air sense of the second air outlet is implemented on the basis that the split and blowing of the airflow can be implemented through at least one second air outlet.
In particular, as shown in fig. 6-D, in this mode, the first wind deflector 10 and the two second wind deflectors 20 are both in a covered state, the airflow of the indoor unit of the air conditioner is divided into three airflows, the first airflow is diffused out through the air diffusing holes on the first wind deflector 10, the second airflow is diffused out through the air diffusing holes on the second wind deflector 20 located at the upper side of the first air outlet, and the third airflow is diffused out through the air diffusing holes on the second wind deflector 20 located at the lower side of the first air outlet. Obviously, in the mode, the air conditioner indoor unit can realize the air outlet without wind sense in a larger range.
Referring to fig. 7 and 8, in the third embodiment of the indoor unit of the air conditioner, the difference between the third embodiment and the first embodiment is that only the second wind guard 20 located above the first wind outlet is provided with a wind-dispersing hole.
As shown in fig. 8-B, only when the first wind deflector 10 is opened, the wind resistance of the first air outlet is small, and most of the air flow of the indoor unit of the air conditioner is blown into the room from the first air outlet, so that the normal air outlet mode is realized.
As shown in fig. 9, in the air conditioning indoor unit of the present embodiment, at least three air-sensing-free air outlet modes can be implemented, unlike the above-described air-sensing-free air outlet modes of the first embodiment, when the airflow of the air conditioning indoor unit flows to the second air outlet above, the airflow passes through the second air baffle 20 through which the air-diffusing holes are formed, and the air speed of the airflow is reduced, so that the second air outlet is implemented without air sensing as compared with the basis of implementing the split-flow blowing of the airflow through the second air outlet.
As shown in fig. 9, in order to enable the first air outlet to realize the air outlet without the wind sense, the air deflector is provided with a plurality of air dispersing holes. When the air deflector rotates to an angle (right angle or acute angle) between the plate surface of the air deflector and the air outlet direction of the air outlet channel, after the air flow passes through the air outlet holes on the air deflector, the air speed of the air flow is reduced, so that the air flow blown to the first air outlet is smaller and softer, and a user cannot feel the flow of the air flow, thereby achieving the effect of no air sensing of the first air outlet.
Referring to fig. 10 and 11, in the fourth embodiment of the indoor unit of the air conditioner, the difference between the fourth embodiment and the third embodiment is that only the second wind guard 20 located below the first wind outlet is provided with a wind-dispersing hole.
As shown in fig. 11-B, only when the first wind deflector 10 is opened, the wind resistance of the first air outlet is small, and most of the air flow of the indoor unit of the air conditioner is blown into the room from the first air outlet, so that the normal air outlet mode is realized.
As shown in fig. 12, in the air conditioning indoor unit of the present embodiment, at least three air-sensing-free air outlet modes can be realized, unlike the air-sensing-free air outlet mode of the third embodiment, when the airflow of the air conditioning indoor unit flows to the second air outlet below, the airflow passes through the second wind deflector 20 through which the air-diffusing holes are formed, and the wind speed of the airflow is reduced, so that the air-sensing-free air outlet of the second air outlet is realized on the basis of realizing the split-flow blowing of the airflow through the second air outlet.
Referring to fig. 13 and 14, in a fifth embodiment of the indoor unit of an air conditioner, the difference between the fifth embodiment and the fourth embodiment is that two second wind shields 20 are each provided with a wind-dispersing hole.
As shown in fig. 14-B, only when the first wind deflector 10 is opened, the wind resistance of the first wind outlet is small, and the wind resistances of the two second wind outlets are large, so that most of the air flow of the indoor unit of the air conditioner blows from the first wind outlet into the room, and a normal wind outlet mode is realized.
As shown in fig. 15, in the air conditioning indoor unit of the present embodiment, at least three air-sensing-free air outlet modes can be implemented, unlike the air outlet effect of the air-sensing-free air outlet mode of the fourth embodiment, when the airflow of the air conditioning indoor unit flows to any one of the second air outlets, the airflow can pass through the second air baffle 20 through which the air-diffusing holes are formed, and the wind speed of the airflow is reduced, so that the air-sensing-free air outlet of the second air outlet is implemented on the basis that the air-sensing-free air outlet of the second air outlet can be implemented at least through one of the second air outlets.
Referring to fig. 16 and 17, in order to realize the adjustable turbulence range of the spoiler 30 in the sixth embodiment of the present invention, based on any of the above embodiments, the number of the spoiler 30 is plural, the plurality of spoiler 30 are spliced in sequence along the length direction of the wind channel 2a, and each spoiler 30 is pivotally connected to the volute 120.
Specifically, each spoiler 30 is disposed in a strip shape, and the plurality of spoilers 30 are spliced in sequence along the extending direction of the air-passing channel 2a, and the side portion, adjacent to the first air outlet, of each spoiler 30 is pivoted with the volute 120, so that the air-passing channel 2a is sectionally disturbed by controlling the number of spoilers 30 to achieve the effect of sectionally disturbing the air, thereby realizing sectionally or completely non-wind-sensing air-out of the first air outlet (as shown in fig. 16).
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
