Detailed Description
Fig. 1 is a schematic side cross-sectional view of an air conditioner indoor wall mount 1 according to one embodiment of the present invention. Referring to fig. 1, the present invention provides an indoor wall unit 1 of an air conditioner. The indoor wall-mounted unit 1 may generally include a frame 20 for supporting a fan and a heat exchanging device 60, a casing 30 covering the frame 20, a panel 40 attached to a front side of the casing 30 for constituting a front portion of the indoor wall-mounted unit 1, and left and right end covers located at left and right sides of the casing 30, and the like. The framework 20, the cover 30, the panel 40 and the left and right end covers can jointly form a shell of the air conditioner indoor wall hanging machine 1.
Further, the casing of the hanging device 1 of the air conditioner indoor wall of the present invention defines a first chamber 100, a second chamber 200 and an air outlet duct 300. The blower and the heat exchange device 60 are disposed inside the first chamber 100, and an air inlet 101 is disposed at the top of the first chamber 100 to allow air to flow into the first chamber 100 and flow through the heat exchange device 60 and the blower for heat exchange and acceleration. The air outlet duct 300 is disposed at the lower end of the first chamber 100, and the end thereof is opened with a transversely disposed air outlet 201 to allow the air in the first chamber 100 to flow out to the surrounding environment through the air outlet duct 300. The indoor wall-mounted unit 1 further has a wind deflector 10, and is configured to be rotatably disposed at the bottom of the casing and at the wind outlet 201 at the end of the wind outlet duct 300, and to controllably open or close the wind outlet duct 300. Specifically, the air deflector can be controlled to rotate to a first rotation position at which the air outlet 201 at the end of the air outlet duct 300 is closed.
Further, the air conditioner indoor wall mount 1 further includes a partition 50. The baffle 50 is disposed between the first and second chambers and is configured to be controllably lowered to obstruct the first and second chambers 100 and 200. That is, when the partition 50 is controllably lowered, the air in the first and second chambers 100 and 200 cannot directly exchange through or across the partition 50.
specifically, the air outlet duct 300 is disposed at the lower ends of the first chamber 100 and the second chamber 200 to allow the air in the first chamber 100 to flow into the second chamber 200 through the air outlet duct 300. Specifically, the second chamber 200 is located at the front side of the first chamber 100 and is configured to be controllably communicated with the air outlet duct 300, so as to allow the air in the first chamber 100 to flow into the second chamber 200 through the air outlet duct 300. That is, the second chamber 200 may be controllably communicated with the first chamber 100 through the air outlet duct 300. Specifically, the air flowing into the first chamber 100 in the housing from the air inlet 101 may flow downward into the air outlet duct 300 through the first chamber 100, and may further flow forward or downward and flow out to the ambient environment through the air outlet 201 from the air outlet duct 300, or continue to flow forward and upward to the second chamber 200. Further, a plurality of ventilation holes 301 are provided on the front surface of the second chamber 200 to allow the air inside the second chamber 200 to be dispersedly flown out to the ambient environment through the plurality of ventilation holes 301.
specifically, when the air deflector 10 rotates to the first rotation position, the air deflector 10 is vertically disposed in an inclined manner, and the lower edge of the air deflector abuts against the lower end of the air outlet 201, and the upper edge of the air deflector is overlapped with the inner side of the front surface of the second chamber 200, so as to close the air outlet 201 at the end of the air outlet duct 300. At this time, there is no partition between the second chamber 200 and the air outlet duct 300, so that the air in the first chamber 100 can flow into and fill the second chamber 200 from the air outlet duct 300, and further can dispersedly flow out from the plurality of air holes 301 formed on the front surface of the second chamber 200.
The plurality of ventilation holes 301 may be uniformly distributed on the front surface of the second chamber 200, and the plurality of ventilation holes 301 may have the same size and be configured to be uniformly distributed from the top to the bottom and from the left to the right on the panel, so that the uniformity of air supply may be improved and the aesthetic property of the wall-mounted air conditioner 1 may be enhanced.
according to the air conditioner indoor wall hanging machine 1, the second chamber 200 which can be communicated with the first chamber 100 through the air outlet duct 300 is arranged, and air gathered in the second chamber 200 can be dispersed and flowed out of the air holes 301 in the front side surface of the second chamber, so that the air is prevented from being blown out from the unobstructed air outlet 201 at a high speed to cause a user to feel discomfort, the air conditioner indoor wall hanging machine 1 achieves non-wind-sense air supply, and the use comfort level of the user is improved.
further, the second chamber 200 has a front side surface provided with a plurality of air holes 301, so that the air outlet area of the second chamber is far larger than that of the air outlet 201 of the existing indoor unit of the air conditioner, and therefore, the wind-free air supply is ensured, and meanwhile, the indoor unit can provide cold energy at least equal to that of the traditional air conditioner within the same working time, the refrigerating/heating efficiency and the refrigerating/heating effect of the wind-free indoor wall-mounted unit 1 of the air conditioner are improved, and therefore the indoor wall-mounted unit 1 of the air conditioner can be applied to a larger space.
Fig. 2 is a schematic side sectional view of the air conditioner indoor wall unit 1 according to one embodiment of the present invention in another state. Referring to fig. 1 and 2, in some embodiments of the present invention, the air deflection assembly 10 is configured to be rotatably coupled to the lower end of the frame 20. Further, the air guiding plate 10 can be controlled to rotate to a second rotation position to open the air outlet 201 and cut off the second chamber 200 and the air outlet duct 300. At this time, the partition 50 may be controllably lifted to communicate the first chamber 100 and the second chamber 200. Therefore, ambient air can enter the second chamber 200 through the plurality of air holes 301, enter the first chamber 100 through the second chamber 200, and then flow into the air outlet duct 300 and flow out from the air outlet 201.
Specifically, when the air deflector 10 rotates to the second rotation position, the air deflector 10 is laterally disposed in an inclined manner, and the upper edge thereof rotates backward and abuts against the rear side surface of the second chamber 200, and the lower edge thereof rotates forward and abuts against the front side surface of the second chamber 200, thereby separating the air outlet duct 300 from the second chamber 200. At this time, the air flowing from the first chamber 100 to the air outlet duct 300 cannot enter the first chamber 100, but directly flows out from the air outlet 201 of the air outlet duct 300 to the surrounding environment. That is to say, the air conditioner indoor wall unit 1 according to the embodiment of the present invention may not only have the no-wind-sensing air supply mode, but also be switched to the ordinary cooling and heating mode according to the user's requirement, thereby improving the user experience.
In some embodiments of the present invention, the air conditioner indoor wall unit 1 further includes a driving shaft 51. The driving shaft 51 is disposed at a front end of the air inlet 101 and configured to have a first rotation direction and a second rotation direction opposite to each other. Further, the diaphragm 50 may be configured to be made of a flexible material. The top end of the flexible partition 50 may be connected to the driving shaft 51 and configured such that when the driving shaft 51 rotates in the first rotation direction, the partition 50 is controlled to be lifted up and wound around the driving shaft 51, and when the driving shaft 51 rotates in the second rotation direction, the partition 50 is controlled to be lowered down and unfolded. Specifically, taking the direction of the views in fig. 1 and 2 as an example, the driving rotation shaft 51 may have a first rotation direction of counterclockwise rotation and a second rotation direction of clockwise rotation.
in some embodiments of the present invention, the first chamber 100 may be formed between the framework 20 and the casing 30, the second chamber 200 may be formed between the panel 40 and the casing 30, and a front surface of the second chamber 200 is formed by at least a portion of the panel 40. That is, the front surface of the second chamber 200 is the panel 40. Further, the housing 30 has a transverse frame (not shown) disposed between the first and second chambers 100 and 200 to define the first and second chambers 100 and 200 at front and rear sides thereof, respectively. In this embodiment, the driving shaft 51 may be disposed at a top end of the transverse frame, and the flexible partition 50 may be lifted and lowered along one side of the transverse frame.
Further, the lateral frame and the partition 50 may be sized substantially equal to the width of the cabinet in the lateral direction, and both left and right ends thereof may extend to the inside of the left and right end covers of the cabinet, respectively, thereby completely isolating the first and second chambers 100 and 200 in the lateral direction.
In some embodiments of the present invention, the heat exchanging device 60 may be disposed in the first chamber 100 in a multi-stage bent manner, and has a width substantially equal to that of the air inlet 101 in a transverse direction, and is configured to extend from a position on a rear side in the first chamber 100 to a position near a rear side of the housing 30 to an upper front side and then to extend to a lower rear side so as to cover a lower side of the air inlet 101 in a front-rear direction, thereby achieving heat exchange of almost all air flowing from the air inlet 101 into the first chamber 100. The cross frame may be configured such that its upper end may extend to the front end of the air intake 101 and its lower end may extend to the lower side of the heat exchange device 60. Accordingly, the partition 50 may be configured such that its lower end extends at least to the lower side of the heat exchange device 60 when it is controlled to descend and obstruct the first and second chambers 100 and 200. That is, the height of the transverse frame and the partition 50 in the vertical direction is not less than the size of the heat exchange device 60 in the vertical direction, so that the air subjected to heat exchange in the first chamber 100 is prevented from flowing into the second chamber 200 through or around the transverse frame and the partition 50.
Further, the housing 30 may further have an extension plate extending from the lower end of the transverse frame to the rear, and the extension plate has a length not less than the thickness of the heat exchanging device 60 in the thickness direction of the air conditioner indoor wall hanging machine 1, so that the heat exchanging device 60 located in the first chamber 100 may be better separated from the air outlet duct 300, and the air in the first chamber 100 may have a sufficient space for heat exchange.
Fig. 3 is a schematic front view of an on-hook air conditioner indoor wall according to one embodiment of the present invention. Referring to fig. 3, in some embodiments of the present invention, the plurality of vent holes 301 are divided into a plurality of rows of vent hole groups in a transverse direction of the panel 40 with equal inter-group intervals between every two adjacent rows of vent hole groups.
That is, the plurality of ventilation holes 301 are substantially uniformly distributed on the panel 40 and the air guide plate 10, so that the number of the ventilation holes 301 per unit area is substantially equal, and thus the air blown through the ventilation holes 301 can be more uniformly distributed.
In some embodiments of the present invention, the cross section of the air hole 301 perpendicular to the axial direction thereof is circular, and the circular air hole 301 is easily manufactured, so that the manufacturing process of the wall-mounted unit 1 of the air conditioner room can be simplified. Of course, the cross section of the ventilation hole 301 may have other shapes, such as an oval shape, a polygonal shape, a long strip shape, etc.
The aperture of the circular air holes 301 ranges from 2 to 6mm, for example, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, and 5.5mm, etc., the minimum distance between every two adjacent air holes 301 ranges from 5 to 12mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, and 11mm, etc., and the specific value thereof can be further selected according to the requirements for the air output and the silencing effect.
in some embodiments of the present invention, the plurality of ventilation holes 301 formed in the panel 40 may be divided into a plurality of first ventilation holes 301a and a plurality of second ventilation holes 301 b. The plurality of first airing holes 301a are obliquely extended in the thickness direction of the panel 40. The first vent hole 301a may be disposed at an inclination angle such that at least a portion of the first outlet air path of the first vent hole 301a and at least a portion of the second outlet air path of the second vent hole 301b intersect at the outer side of the panel 40.
Fig. 4 is a schematic view of an air path of the panel 40 according to an embodiment of the invention. Referring to fig. 4, the wind direction of the wind blown out from the first ventilation holes 301a is inclined downward, and a cluster of straight lines located above in fig. 4 shows the wind path of the wind blown out after passing through the first ventilation holes 301 a. The lower straight line in fig. 4 shows the path of the wind blown out after the wind passes through the second ventilation holes 301 b. Therefore, the air flowing out of the first air hole 301a and the air flowing out of the second air hole 301b interfere with each other to change the original flowing direction, so that the turbulent air supply is realized, and the direct blowing of the air to the user can be almost completely avoided. Of course, the first vent hole 301a may be disposed below the second vent hole 301b and configured to extend obliquely upward.
According to the panel 40, the air is obliquely supplied through the part of the air holes, so that refrigeration or heating air blown out of the part of the air holes can interfere with air blown out of at least another part of the air holes, the two parts of the air are crossed to form turbulent air, the air is not directly blown out, and the non-wind experience is enhanced.
furthermore, because the panel 40 of the present invention can send out wind in different directions and mix and intersect the wind in multiple directions, the air supply area of the air holes can have a size slightly larger than that of the existing air supply micropores, so that the air outlet quantity is larger, and the air-conditioning refrigeration or heating efficiency is improved.
Further, since the plurality of first ventilation holes 301a having a downward inclination angle are located at the upper portion of the panel 40, the second ventilation holes 301b can realize cross air supply without providing an inclination angle. That is, when the blowing direction of the second ventilation hole 301b is parallel to the thickness direction of the panel 40, the wind blown out from the second ventilation hole 301b may cross the wind blown out from the first ventilation hole 301 a. Thus, the panel 40 can be ensured to have high structural strength, and the manufacturing process thereof can be simplified.
in some embodiments of the present invention, the plurality of second ventilation holes 301b may also be obliquely extended in the thickness direction of the panel 40, and are configured to enable the second air outlet path to be obliquely upward from the front surface of the panel 40. That is, the second ventilation hole 301b may have a certain inclination angle, so that the wind blown out from the second ventilation hole 301b can be mixed and crossed with the wind blown out from the first ventilation hole 301a at a position closer to the outer surface of the panel 40, thereby enhancing the effect of cross wind blowing of the wall-mounted air conditioner 1.
