Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 11 show a preferred embodiment of the present invention.
The air conditioning indoor unit 10 includes a casing including a vertically arranged peripheral wall (an angle of less than forty-five degrees from a vertical plane can be referred to as a vertical arrangement), a horizontally arranged bottom wall 150 at a lower end of the peripheral wall, and a top wall 130 at an upper end of the peripheral wall. The peripheral walls include a first wall plate 110, a second wall plate 120 intersecting the first wall plate 110, and a wind outlet wall 140. After the air conditioning indoor unit 10 is installed, the first wall plate 110 and the second wall plate 120 may be respectively and correspondingly attached to or close to two intersecting indoor vertically-arranged wall surfaces, that is, the air conditioning indoor unit 10 may be installed at an indoor corner, and specifically, the first wall plate 110 and/or the second wall plate 120 may be connected to an indoor wall, so as to implement installation of the air conditioning indoor unit 10. Because the casing of the indoor unit 10 of the air conditioner can be arranged at the indoor corner, the pipeline assembly can directly pass through the opening at the indoor corner to be connected with the outdoor unit of the air conditioner, the installation difficulty of the air conditioner is reduced, the length of the pipeline assembly is reduced, the production cost is reduced, meanwhile, the indoor unit 10 of the air conditioner can cover the pipeline opening on the wall, and the room tightness is improved.
The bottom wall 150 of the housing is provided with an air inlet 151, and the air outlet wall 140 is provided with two air outlets 141 (in other embodiments, one air outlet or a plurality of air outlets may also be provided). Indoor air enters the shell from the air inlet 151, exchanges heat with the heat exchanger 200 in the shell, and is led out to the indoor through the two air outlets 141. The air inlet 151 is disposed on the bottom wall 150, so that the heat exchange airflow ejected from the air outlet 141 can be effectively prevented from flowing back into the housing through the air inlet 151, and the air outlet 141 is disposed on the vertically arranged air outlet wall 140, so that the heat exchange airflow can have a longer air outlet distance. Further, the two air outlets 141 of the indoor air conditioner 10 correspondingly lead out two air flows, and the projections of the two air flows in the horizontal plane form a preset included angle, that is, the two air flows are led out to the indoor space in two horizontal crossing directions. Specifically, the preset included angle may be between sixty degrees and one hundred twenty degrees.
In order to achieve the purpose that the projections of the two air flows correspondingly ejected from the two air outlets 141 in the horizontal plane form a preset included angle, in an embodiment, the shape of the air outlet 141 may be designed so that the air outlet 141 guides the guided air flow. In another embodiment, the two outlets 141 may be respectively provided with a guide device to make the ejected air flows cross in the horizontal direction. In another embodiment, each of the air outlets 141 may be provided with a cross-flow fan, so that the air blowing directions of the two cross-flow fans are horizontally crossed. In another embodiment, a centrifugal fan may be provided to supply air to the two air outlets simultaneously, and the two air outlets are oriented to form an included angle, so that the air flows ejected from the two air outlets 141 intersect in the horizontal direction. It should be understood that no matter how the intersection of the air flows ejected from the two air outlets 141 in the horizontal direction is achieved, the included angle of the horizontal plane projection of the two air flows can be considered to be within the protection scope of the present application.
Because the indoor unit 10 of the air conditioner is disposed at an indoor corner, two air flows ejected from the two air outlets 141 of the indoor unit 10 of the air conditioner can extend to an indoor diagonal position opposite to the indoor unit 10 along two directions, and the two air flows extending to the indoor diagonal position opposite to the indoor unit 10 meet the obstruction of a wall surface to generate convolution, so that two air flow vortices can be generated on two sides of the diagonal line of a room respectively, on one hand, the heat exchange efficiency of heat exchange air ejected from the indoor unit 10 is enhanced, on the other hand, direct blowing of the heat exchange air to a user is avoided, and the air outlet effect is enhanced. And also allows the heat-exchange air flow ejected from the indoor unit 10 disposed at the indoor corner position to radiate the entire indoor. In a preferred embodiment, the two air flows from the two air outlets 141 can be parallel to the first wall plate 110 and the second wall plate 120 in a one-to-one correspondence. Because the first wall plate 110 and the second wall plate 120 are correspondingly attached to two indoor wall surfaces, the heat exchange air flows ejected from the two air outlets 141 are parallel to the two indoor wall surfaces one by one, so that the air flows ejected from the two air outlets 141 can flow by being attached to the indoor wall surfaces, and the two air flows more easily swirl at opposite corners of the indoor space opposite to the indoor unit 10 to generate air flow vortices.
In one embodiment, the two outlets 141 are arranged up and down, and the guiding device is used to make the air flow ejected from the two outlets 141 arranged up and down intersect horizontally. In another embodiment, the two air outlets 141 have the same horizontal height, and after the two air flows ejected from the two air outlets 141 are projected on the vertical plane, the included angles between the two projections and the horizontal plane are the same, that is, the two air flows ejected from the two air outlets 141 are coplanar. The air outlets 141 having the same horizontal height may make the vertical size of the indoor unit 10 smaller, thereby facilitating installation. Meanwhile, two air flows ejected from the two air outlets 141 can be more synchronous, so that two air flows at two sides of an indoor diagonal are more stable in vortex.
The included angle between the first wall plate 110 and the second wall plate 120 may be determined according to the included angle between two vertical walls at the indoor corner, but most of the indoor space is rectangular, so in one embodiment, the first wall plate 110 and the second wall plate 120 may be perpendicular to each other, so as to enable the air-conditioning indoor unit 10 to meet most practical requirements.
In an embodiment, from top to bottom, the two blowing surfaces are arranged obliquely in the housing, so that the air flows guided out of the two air outlets 141 are all inclined downward. The downward inclination of the heat exchange airflow may allow the heat exchange airflow, which is blown out from the outlet 141, to sink and exchange heat with air having a low vertical height in the room when the heat exchange airflow is hot air.
In order to provide the air conditioning indoor unit 10 with a concealing effect, the top wall 130 may be adapted to fit to an indoor ceiling. When the air-conditioning indoor unit 10 is disposed to be attached to an indoor ceiling, the top wall 130 may be connected to the ceiling, and a connection structure is disposed between the first wall plate 110 and the second wall plate 120 and the wall surface that is vertically disposed in the room, that is, the connection structure of the top wall 130 and the ceiling bears all the gravity of the air-conditioning indoor unit 10, and the air-conditioning indoor unit 10 is hung on the ceiling. The air-conditioning indoor unit 10 is installed in such a manner that the installation can be performed by one installation point, and the installation difficulty is reduced. The arrangement that the indoor air-conditioning indoor unit 10 is attached to the indoor top plate enables air flow guided out of the indoor air-conditioning indoor unit 10 to flow attached to the indoor top plate, and when the heat exchange air flow is cold air, the lift of the heat exchange air flow can be increased.
The air conditioning indoor unit 10 may further include a fan-shaped casing 400, the fan-shaped casing 400 wraps the rectangular casing, the fan-shaped casing 400 includes a fan-shaped top plate, a fan-shaped bottom plate 410 and a side plate 420 located between the fan-shaped top plate and the fan-shaped bottom plate, the side plate 420 includes two peripheral walls respectively attached to the first wall plate 110 and the second wall plate 120 one by one and an arc-shaped wall connecting the two peripheral walls, the arc-shaped wall is provided with two positions corresponding to the air outlets 141 one by one to form openings, the fan-shaped casing 400 may extend a section of arc-shaped flange at each of the two air outlets 141, the arc-shaped flange may effectively protect the air.
The existing indoor unit of the air conditioner generally comprises a centrifugal fan, and in the whole process from air inlet to air outlet of the centrifugal fan, circulating air flow needs to be bent for two times by 90 degrees, and each turning is accompanied with more air loss. In addition, the centrifugal fan generally needs several tens of large-sized blades to increase wind pressure and wind volume, and when the centrifugal fan operates, the blades rotate to generate friction with air or generate impact. The centrifugal fan has wide blades and a large thickness, and thus generates a very large noise when the motor 30 of the centrifugal fan is operated at a high speed. In addition, a cross-flow fan is commonly used in the prior art, but although the noise of the cross-flow fan is low, the wind pressure is too small, and the air supply distance is short; and the whole volume of the cross flow fan is large, and the actual effective volume is small, so that the space waste is caused. In this embodiment, since there are many positioning points of the casing of the air-conditioning indoor unit, the casing is not prone to shaking after being installed, and the generated noise is low, in order to further reduce the generated noise, in an embodiment, a laminar flow fan 300 may be disposed in the air-conditioning indoor unit, the laminar flow fan 300 is used for drawing indoor air into the casing from the air inlet 151 and then guiding the indoor air out to the room from the air outlet 141, and the laminar flow fan 300 is configured to generate centrifugal airflow by using viscous force. Further, the laminar flow fan 300 includes a plurality of annular disks 10 and a motor 30. A plurality of annular disks 10 are arranged in parallel spaced apart relationship with the same central axis arranged vertically. The motor 30 is configured to drive the plurality of annular disks 10 to rotate, so that the plurality of annular disks 10 contact with each other and move with each other, and further, an air boundary layer near the surfaces of the plurality of annular disks 10 is driven by the plurality of annular disks 10 rotating due to a viscous effect to rotate from inside to outside to form laminar air. That is, as shown in fig. 10, during the rotation of the annular disk 10, the air at the center rotates along with the annular disk 10 to generate centrifugal action and then spreads out, and after the air spreads to contact the annular disk 10, the air is thrown out of the annular disk 10 to form an air flow because the centrifugal action of the air is increased by the viscous force of the surface of the annular disk 10. The air outlet mode can reduce noise to a greater extent, so that the indoor unit of the air conditioner is quieter when working.
In order to make the air intake of the laminar flow fan 300 smoother, in an embodiment, the air intake 151 may be circular, and the center of the air intake 151 coincides with the center of the annular disk 10 in the vertical direction, so that the indoor air can better flow into the center of each annular disk 10, thereby making the air supply of the laminar flow fan 300 smoother.
In one embodiment, as shown in fig. 8, the inner diameters of the plurality of annular disks 10 gradually decrease from bottom to top, and a central angle θ is formed by connecting the inner diameter and the outer diameter of the plurality of annular disks 10 on the same longitudinal section passing through the central axis. The inner diameters of the plurality of annular disks 10 are gradually reduced from bottom to top, so that the air volume of the laminar flow fan 300 can be effectively increased, and the air outlet of the laminar flow fan 300 meets the use requirements of users.
In fig. 11, the abscissa axis θ indicates a central angle of a connecting line of the inner diameter and the outer diameter of the plurality of annular disks 10 on the same longitudinal section passing through the central axis, the left ordinate axis Mass flow rate indicates an air volume, the right ordinate axis Pressure indicates an air Pressure, and the air Pressure indicates a Pressure difference between the air outlet 141 and the air inlet channel of the laminar flow fan 300. Specifically, fig. 11 is a schematic diagram illustrating the relationship between the central angle θ and the air volume and the air pressure when the outer diameter, the number of layers, the distance, the thickness of the annular disk 10 and the rotation speed of the motor 30 of the laminar flow fan 300 are all kept unchanged. As shown in fig. 11, when the above-mentioned parameters are all kept constant, as the central angle θ is gradually increased, the air volume of the laminar flow fan 300 is increased and then decreased, and the air pressure slightly increases. In a preferred embodiment, the outer diameter of the annular disk 10 of the laminar flow fan 300 is 175 mm, the number of layers of the annular disk 10 is layers, the pitch of the annular disks 10 is 13.75 mm, the thickness of the annular disk 10 is 2 mm, and the rotation speed of the motor 30 is 1000rpm (revolutions per minute), and in consideration of the air volume and the air pressure, the central angle θ of the inner and outer diameter connecting lines of the plurality of annular disks 10 on the same longitudinal section passing through the central axis may be set to be 9 ° to 30 °. And as shown in fig. 11, when the central angle θ is set to 15 °, the air volume of the laminar flow fan 300 reaches the maximum value.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
