Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
An air conditioning indoor unit 100 according to an embodiment of the first aspect of the present invention is described below with reference to the accompanying drawings, where the air conditioning indoor unit 100 may be a cabinet or a hanging machine.
As shown in fig. 1 and 2, an air conditioning indoor unit 100 according to an embodiment of the first aspect of the present invention includes: an air outlet frame member 1 and a duct mounting plate 2.
Specifically, the air outlet frame component 1 may include an air outlet frame 11, in which an air outlet channel 111 and a sealing channel 112 are formed in the air outlet frame 11 and connected in an axial direction, where the sealing channel 112 is located upstream of the air outlet channel 111 in a direction of airflow (for example, a direction from back to front as shown in fig. 2), that is, when airflow flows, the airflow passes through a position corresponding to the sealing channel 112 first, and then flows to the air outlet channel 111.
At least one first sealing rib 113 extending along the circumferential direction of the sealing channel 112 is arranged on the inner wall of the sealing channel 112; for example, the first sealing bead 113 may be formed as an annular sealing bead along a circumferential circumference of the sealing passage 112. Here, the number of the first sealing beads 113 may be one, two, three, etc., and thus, the number of the first sealing beads 113 may be set according to actual sealing requirements in combination with structural features of the sealing passage 112.
The air duct mounting plate 2 is connected with the air outlet frame component 1, the air duct mounting plate 2 is positioned on one side of the sealing channel 112 of the air outlet frame 11, and the air duct mounting plate 2 is provided with the air duct component 3. Here, the air duct member 3 may be integrally formed with the air duct mounting plate 2, and of course, the air duct member 3 and the air duct mounting plate 2 may be separately formed and then be assembled and connected together. Further, the air channel member 3 is opposed to the air outlet frame 11, for example, the air channel member 3 and the air outlet frame 11 may be opposed in the front-rear direction shown in fig. 2. And the air channel member 3 is located upstream of the air outlet frame 11 in the airflow direction (e.g., the rear side of the air outlet frame 11 shown in fig. 2).
One end of the air channel member 3 (e.g., the front end of the air channel member 3 shown in fig. 3) protrudes into the sealing channel 112, and one end of the air channel member 3 (e.g., the front end of the air channel member 3 shown in fig. 3) is formed with at least one second sealing rib 31, which second sealing rib 31 extends around the axis of the air channel member 3, the second sealing rib 31 being staggered with the first sealing rib 113 in the axial and/or radial direction of the sealing channel 112. For example, the first sealing beads 113 and the second sealing beads 31 may be staggered in the axial direction of the sealing passage 112, the first sealing beads 113 and the second sealing beads 31 may be staggered in the radial direction of the sealing passage 112, and when the first sealing beads 113 and the second sealing beads 31 each include a plurality of the first sealing beads 113 and the second sealing beads 31 may be partially staggered in the radial direction and partially staggered in the axial direction.
In this way, the first sealing rib 113 and the second sealing rib 31 may cooperate to form a multi-layered duct sealing structure along the axial direction (or radial direction) of the sealing channel 112, i.e., the first sealing rib 113 and the second sealing rib 31 may cooperate to form a labyrinth seal. Thus, the air leakage and the air flow back flow can be effectively prevented by the cooperation of the first sealing rib 113 and the second sealing rib 31. In addition, by arranging the first sealing ribs 113 on the inner wall of the sealing channel 112, the strength of the air outlet frame 11 can be further enhanced, and the service life of the air outlet frame 11 can be prolonged.
According to the air conditioning indoor unit 100 of the embodiment of the invention, the first sealing ribs 113 are arranged on the inner wall of the sealing channel 112, the second sealing ribs 31 are arranged at one end of the air duct member 3 extending into the sealing channel 112, and the first sealing ribs 113 and the second sealing ribs 31 are arranged in a staggered manner, so that an air duct sealing structure can be formed by utilizing the first sealing ribs 113 and the second sealing ribs 31 which are matched in multiple layers, air leakage and air flow backflow of the air outlet channel 111 can be effectively prevented, and meanwhile, the strength of the air outlet frame 11 and the air duct member 3 can be improved.
In one embodiment of the present invention, as shown in fig. 3, one end of the first sealing rib 113 in the axial direction (e.g., a front end of the first sealing rib 113 shown in fig. 3) is connected to the inner wall of the sealing passage 112, the other end of the first sealing rib 113 (e.g., a rear end of the first sealing rib 113 shown in fig. 3) extends in the axial direction of the sealing passage 112 in a direction away from the air outlet passage 111 (e.g., a front-to-rear direction in fig. 3), and the other end of the first sealing rib 113 is spaced apart from the inner wall of the sealing passage 112.
Further, as shown in fig. 3, one end of the second sealing rib 31 (e.g., the rear end of the second sealing rib 31 shown in fig. 3) is connected to the outer wall of the air channel member 3, and the other end of the second sealing rib 31 (e.g., the front end of the second sealing rib 31 shown in fig. 3) extends toward the first sealing rib 113 in the axial direction of the air channel member 3, and the second sealing rib 31 is offset from the first sealing rib 113 in the radial direction of the sealing channel 112. Thus, the first sealing rib 113 and the second sealing rib 31 can jointly form a labyrinth sealing structure (air duct sealing structure) with multiple layers of cooperation inside and outside in the radial direction, and the effects of air leakage prevention and air flow backflow prevention are achieved. In addition, the first sealing rib 113 and the second sealing rib 31 can also play a role in positioning and guiding, so that the installation of the air outlet frame component 1 is facilitated.
In some examples, as shown in fig. 3, the first sealing bead 113 and the second sealing bead 31 at least partially overlap in a projection plane parallel to the axis of the sealing channel 112. That is, the first sealing bead 113 and the second sealing bead 31 overlap at least partially inside and outside in the axial direction of the sealing passage 112. Thereby, the sealing effect can be further improved.
In some embodiments of the present invention, as shown in fig. 3 in combination with fig. 2, the first sealing rib 113 is formed with a relief slope 1132, and the relief slope 1132 extends obliquely from the inner surface of the first sealing rib 113 to the free end face of the first sealing rib 113 along the radial direction of the sealing channel 112. Therefore, by providing the avoiding inclined surface 1132, the first sealing rib 113 can be matched with the outer wall surface of the air duct member 3, so that collision between the first sealing rib 113 and the air duct member 3 can be avoided.
In some embodiments, as shown in fig. 5 in combination with fig. 2, the radial dimension of the seal channel 112 gradually increases in a direction from the air outlet frame 11 toward the air channel member 3 (e.g., a forward-backward direction in fig. 5). Further, the radial dimension of the outer wall of the air channel member 3 gradually decreases in the direction from the air channel mounting plate 2 toward the air outlet frame member 1. Therefore, the inner wall of the sealing channel 112 is more matched with the outer wall of the air duct piece 3, so that the gap between the inner wall of the sealing channel 112 and the outer wall of the air duct piece 3 can be reduced to reduce air leakage, and meanwhile, the mutual interference between the inner wall of the sealing channel 112 and the outer wall of the air duct piece 3 is avoided, and the structure is more reasonable.
In some embodiments of the present invention, as shown in fig. 4, the first sealing rib 113 may be formed with a first wiring groove 1131 penetrating the first sealing rib 113 in a thickness direction, that is, the first sealing rib 113 is formed with the first wiring groove 1131, and the first wiring groove 1131 penetrates the first sealing rib 113 in the thickness direction of the first sealing rib 113. Therefore, the motor wiring can be facilitated while the sealing leakage-proof effect is realized.
In some embodiments, as shown in fig. 6, the second sealing rib 31 may be formed with a second wiring groove 311, and the second wiring groove 311 penetrates the second sealing rib 31 in a thickness direction. Therefore, the motor wiring can be facilitated while the sealing leakage-proof effect is realized.
In some embodiments of the present invention, as shown in fig. 2, the air outlet frame member 1 may further include: a first support plate 12 and a second support plate 13, wherein the second support plate 13 is located at a side of the first support plate 12 away from the duct mounting plate 2 (e.g., a front side of the first support plate 12 shown in fig. 2), and both ends of the second support plate 13 in a length direction (e.g., an up-down direction shown in fig. 2) and both ends of the first support plate 12 in the length direction are connected to define an air guiding space 14, respectively. The air outlet frame 11 is disposed in the air guiding space 14, and two axial ends of the air outlet frame 11 extend to the first support plate 12 and the second support plate 13 respectively. Thereby, the air outlet frame 11 can be conveniently and fixedly installed.
The air outlet frame, the first support plate and the second support plate can be arranged in a split mode, and the air outlet frame is connected with the first support plate and the second support plate through assembly. Of course, the present invention is not limited thereto, and the air outlet frame may be integrally formed with the first support plate.
In some examples, as shown in fig. 4, the air outlet frame 11 may include an upper air outlet frame 11a and a lower air outlet frame 11b disposed in the air guiding space 14 at intervals along the up-down direction, wherein two first routing grooves 1131 may be formed on the upper air outlet frame 11a, and the two first routing grooves 1131 penetrate the top and the bottom of the first sealing rib 113 along the thickness direction of the first sealing rib 113, that is, one of the two first routing grooves 1131 is formed on the top of the first sealing rib 113 and the other is formed on the bottom of the first sealing rib 113; two first wire grooves 1131 may be used for motor wires.
Further, as shown in fig. 4, a first wiring groove 1131 penetrating the first sealing rib 113 obliquely below in the thickness direction of the first sealing rib 113 may be formed on the lower air outlet frame 11b, that is, the first wiring groove 1131 on the lower air outlet frame 11b is formed obliquely below the first sealing rib 113. Thus, the motor wiring can be facilitated.
In some examples, as shown in fig. 6 in combination with fig. 2, the air duct member 3 may include an upper air duct member 3a and a lower air duct member 3b provided on the air duct mounting plate 2 at intervals in the up-down direction, wherein two second wiring grooves 311 penetrating the top and bottom of the second sealing ribs 31, respectively, in the thickness direction of the second sealing ribs 31 are formed on the upper air duct member 3 a; that is, one of the two second wiring grooves 311 is formed at the top of the second sealing rib 31, and the other is formed at the bottom of the second sealing rib 31; two second wire grooves 311 may be used for motor wires.

Further, the first wiring grooves 1131 and the second wiring grooves 311 are in one-to-one correspondence. Therefore, wiring can be facilitated, and the structure is simpler and more reasonable.
It is to be understood that in the above description, the terms "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the invention and simplify description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and thus should not be construed as limiting the invention.
An air conditioning indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an air conditioning indoor unit 100 includes: the air outlet frame component 1, the air duct mounting plate 2, the first fan 4 and the second fan 5.
Specifically, as shown in fig. 2, the air duct mounting plate 2 is provided with an upper air duct member 3a and a lower air duct member 3b which are arranged at intervals in the up-down direction, the first fan 4 is arranged at the position of the upper air duct member 3a, and the second fan 5 is arranged at the position of the lower air duct member 3 b.
As shown in fig. 2, the first fan 4 is a counter-rotating fan, that is, the first fan 4 includes a first wind wheel 41 and a second wind wheel 42, and the inclination direction of the blades of the first wind wheel 41 is opposite to that of the blades of the second wind wheel 42, the first wind wheel 41 and the second wind wheel 42 are mutually guide vanes in the air flowing direction, so that the tangential rotation speed (i.e., dynamic pressure is converted into static pressure) of the air flow is reduced (under the condition that the first wind wheel 41 and the second wind wheel 42 are at different rotation speeds) or eliminated (under the condition that the first wind wheel 41 and the second wind wheel 42 are at the same rotation speed), the working efficiency of the counter-rotating fan on the air is improved, and the air flows through the two wind wheels all flow towards the direction of the air outlet, thereby realizing the effect of remote air supply. It should be noted that, compared with a single cross flow fan, axial flow fan or diagonal flow fan, the first wind wheel 41 and the second wind wheel 42 in the counter-rotating fan can realize the air supply of a longer distance for the counter-rotating fan regardless of the counter-rotation at different speeds or the counter-rotation at the same speed.
Secondly, the first wind wheel 41 and the second wind wheel 42 can expand the cold air conveying range under the condition of different rotating speeds. Because when one wind wheel rotates at a higher rotating speed and the other wind wheel rotates at a lower rotating speed, the wind wheel with the higher rotating speed plays a leading role, and the blade air outlet angle design based on the single-stage axial flow or diagonal flow fan deviates from the direction of the rotating shaft, the axial flow wind wheel or the diagonal flow wind wheel has a wind dispersing effect, so that the angle range of cold air flowing out from a first air outlet opposite to the first fan 4 is larger, and wide-angle air supply is realized. In addition, based on the wind dispersing effect of the axial flow wind wheel or the diagonal flow wind wheel, the rotating speeds of the first wind wheel 41 and the second wind wheel 42 can be adjusted according to the requirement, so that the differential rotation of the first wind wheel and the second wind wheel is realized, soft wind sense or wind sense-free air supply is realized, and bad experience of direct blowing of cold air after the cold air flows out from the first air outlet to users is avoided. Therefore, the air conditioning indoor unit 100 of the present embodiment can realize soft air feeling or air supply without air feeling without using an air deflector with micro holes, and has less air volume loss. In order to realize wide-angle air supply and air supply without wind sense, the motor corresponding to one wind wheel does not work, and the other wind wheel still supplies air towards one side of the air outlet. In addition, in order to realize wide-angle air supply and air supply without wind sense, one wind wheel can also reversely supply air to the inner side of the shell, and the other wind wheel can still supply air positively. The positive air supply is that the air flow is blown out from the air outlet under the action of the wind wheel, and the negative air supply is that the air flow is blown into the inner side of the shell. According to the indoor unit 100 of the air conditioner of the embodiment, by arranging the first fan 4, the first fan 4 is a counter-rotating fan, the effect of long-distance air supply can be achieved, meanwhile, when the first wind wheel 41 and the second wind wheel 42 operate in a differential mode, soft air feeling or air supply without air feeling can be achieved without arranging an air deflector with micropores, and the air quantity loss is small.
The second fan 5 may be a counter-rotating fan, and the second fan 5 may also be a cross-flow fan, an axial-flow fan or an oblique-flow fan.
As shown in fig. 2, the air outlet frame component 1 comprises a first support plate 12, a second support plate 13 and two air outlet frames 11, wherein the second support plate 13 is located on one side of the first support plate 12 far away from the air duct mounting plate 2, and two ends of the second support plate 13 in the length direction and two ends of the first support plate 12 in the length direction are respectively connected to define an air guiding space 14. The two air outlet frames 11 are arranged in the air guide space 14 at intervals along the up-down direction, and the two axial ends of the air outlet frames 11 respectively extend to the first support plate 12 and the second support plate 13.
The two air outlet frames 11 are respectively provided with an air outlet channel 111 and a sealing channel 112, and the radial dimension of the inner wall of the sealing channel 112 is gradually increased along the direction of axially deviating from the air outlet channel 111. The inner wall of the sealing channel 112 is provided with a first sealing rib 113, the first sealing rib 113 is in a ring shape extending along the circumferential direction, and the first sealing rib 113 extends along the direction of the circumference Xiang Chaoxiang away from the air outlet channel 111.
