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 form a shell of the hanging machine 1 in the air conditioner room.
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 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 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 be further guided by the air outlet duct 300 to flow downward and forward to the ambient environment through the air outlet 201, or flow upward and forward to the second chamber 200. Further, the front surface of the second chamber 200 may be divided into two parts, respectively: a first portion 21 having a continuous closed surface and a second portion 22 having a plurality of ventilation holes 301 formed therein to allow air within the second chamber 200 to flow out to the ambient environment through the plurality of ventilation holes 301 formed in the second portion 22.
Specifically, the second portion 22 of the front surface of the second chamber 200 may be provided with a plurality of ventilation holes 301 uniformly or in other patterns to allow the air in the second chamber 200 to flow out to the surrounding environment through the plurality of ventilation holes 301. Therefore, the air outlet quantity of the air conditioner can be increased while the condition that the air outlet of the hanging machine 1 on the inner wall of the air conditioner cannot be directly blown to a user is ensured.
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 from the air holes 301 and the air grooves 302 on 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 uncomfortable, 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, so that 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 further, 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. Specifically, the air deflector 10 can be controlled to rotate to the first rotation position, seal the air outlet 201, and communicate the second chamber with the air outlet duct 300, so that the air in the first chamber 100 enters the second chamber 200 through the air outlet duct 300. That is, 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.
Further, the air deflector 10 may also be controlled to rotate to a second rotation position, open the air outlet 201, and cut off the second chamber and the air outlet duct 300, so as to prevent the air in the first chamber 100 from entering the second chamber 200 through the air outlet duct 300. That is, when the air deflector 10 is rotated to the second rotation position, the air deflector 10 is laterally disposed in an inclined manner, and the upper edge thereof is rotated backward and abuts against the rear side surface of the second chamber 200, and the lower edge thereof is rotated forward and abuts against the front side surface of the second chamber 200, thereby separating the 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 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 cover 30 has a transverse partition 50 disposed between the first chamber 100 and the second chamber 200 to prevent air in the first chamber 100 from flowing through the cover 30 into the second chamber 200. Likewise, air in the second chamber 200 is not able to enter directly into the first chamber 100 due to the provision of the transverse partition 50. That is, the portion of the housing 30 between the first chamber 100 and the second chamber 200 is a removable or non-removable transverse partition 50 having a continuous surface, and the transverse partition 50 prevents the first chamber 100 and the second chamber 200 from direct gas exchange.
Further, the transverse partition 50 has a size in the transverse direction substantially equal to the width of the cabinet, and left and right ends thereof may extend to the inside of the left and right end covers of the cabinet, respectively, to completely separate the first and second chambers 100 and 200 in the transverse direction.
In some embodiments of the present invention, the transverse partition 50 is also configured to be controllably elevationally disposed between the first chamber 100 and the second chamber 200 to communicate or block the first chamber 100 and the second chamber 200. That is, when the horizontal partition 50 is lowered to separate the first chamber 100 from the second chamber 200, the air conditioner indoor wall unit 1 can perform the above-described non-windy blowing function. When the transverse partition 50 is raised and the first and second chambers 100 and 200 are installed, the air conditioner indoor wall-mounted unit 1 can perform general rapid air supply, so that different requirements of users can be satisfied, and selection of an air supply mode of the air conditioner indoor wall-mounted unit 1 can be more flexible.
Further, in the present embodiment, the indoor wall unit 1 may further include a driving shaft (not shown). The driving shaft may be 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. The transverse partition 50 may be configured to be made of a flexible material. The top end of the flexible transverse partition 50 may be connected to the driving shaft and configured such that when the driving shaft rotates in the first rotation direction, the transverse partition 50 is controlled to be lifted up and wound up on the driving shaft, and when the driving shaft rotates in the second rotation direction, the transverse partition 50 is controlled to be lowered down and unfolded, thereby making the lifting operation of the transverse partition 50 more convenient and faster.
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 transverse partition 50 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 underside of the heat exchange device 60. That is, the height of the transverse 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 directly flowing into the second chamber 200 through or bypassing the transverse partition 50.
Further, the housing 30 may further have an extension plate extending from the lower end of the transverse partition plate 50 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.
In some embodiments of the invention, the side of the transverse partition 50 facing the panel 40 is at least partially concave, and the lower end of the transverse panel 40 is configured with at least one recess. Further, the recess is formed with a communication port to guide the air in the air outlet duct 300 to flow into the second chamber 200.
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 invention, the first portion 21 is configured to be positioned above the second portion 22 and occupy no more than 1/2 of the front surface of the second chamber 200, such as 1/10, 1/9, 1/8, 1/7, 1/6, 1/5, 1/4, 1/3, etc., of the front side surface of the second chamber 200. Therefore, the air conditioner indoor wall-mounted unit 1 can be provided with a position where an outer member such as a logo, a mark and a display panel can be arranged while ensuring that the air conditioner indoor wall-mounted unit has enough air holes 301 for air supply.
That is, the first portion 21 of the front surface of the second chamber 200 may be disposed at an upper position with respect to the second portion 22. Therefore, a certain relatively closed space can be formed above the inside of the second chamber 200 to install a control device such as a control main board, and an additional installation box or an installation plate is not needed, so that the manufacturing cost of the wall-mounted unit 1 in the air conditioner room is reduced.
Further, since the mounting position of the indoor wall-mounted unit 1 is generally high in the home of the user, under the condition that a large number of air holes 301 are formed and the air supply amount can be ensured, a plurality of air holes 301 located at the upper portion are omitted, the air supply effect of the indoor wall-mounted unit 1 is not affected, the manufacturing process of the casing of the indoor wall-mounted unit can be simplified, and the manufacturing cost is reduced. In addition, the second chamber 200 having the at least partially closed front side surface may further enhance the structural strength of the wall-mounted unit 1 of the air conditioner room, and improve the operational stability thereof.
Fig. 4 is a schematic front view of an indoor wall unit 1 of an air conditioner according to another embodiment of the present invention. Referring to fig. 4, in some embodiments of the present invention, the plurality of ventilation holes 301 may be configured to be distributed in a specific pattern, for example, some design patterns or product marks, so as to increase the aesthetic degree of the panel and the brand recognition of the on-hook 1 in the air conditioner room while achieving the air blowing function, save additional decorations, and reduce the manufacturing cost.
Referring to fig. 3 and 4, 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.
Further, the air guiding plate 10 may also be uniformly provided with a plurality of air holes 301, and the air holes are configured to be divided into a plurality of lower air hole groups in the transverse direction of the air guiding plate 10, and the plurality of lower air hole groups may be configured to be aligned with the plurality of air hole groups on the panel 40.
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 ventilation hole 301 perpendicular to the axial direction thereof is circular, and the circular ventilation hole 301 is easily manufactured, so that the manufacturing process of the wall-mounted air conditioner 1 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 is in a range of 2 to 6mm, for example, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, and 5.5mm, etc., and the minimum distance between every two adjacent air holes 301 is in a range of 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. 5 is a schematic view of an air path of the panel 40 according to an embodiment of the invention. Referring to fig. 5, 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. 5 shows the wind path of the wind blown out after passing through the first ventilation holes 301 a. The lower straight line in fig. 5 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.
The present invention also provides a control method of an indoor wall-mounted unit 1, which can be executed by the indoor wall-mounted unit 1 according to any of the above embodiments. Specifically, the air conditioner indoor wall-mounted unit 1 has a micro-hole blowing mode in which the air outlet 201 is completely closed by the air guide plate 10 and air is blown only through the plurality of air holes 301, and a high-speed blowing mode in which the air guide plate 10 is completely opened and air is blown through the air outlet 201. That is, when the air deflector 10 rotates to the first rotation position, the indoor wall unit 1 operates in the micro-hole blowing mode, and when the air deflector 10 rotates to the second rotation position, the indoor wall unit 1 operates in the high-speed blowing mode.

step S112, detecting whether the indoor temperature deviates from the preset temperature when the wall-mounted unit 1 of the air conditioner indoor runs;
if so, operating the high-speed air supply mode, and otherwise, operating the micropore air supply mode.
Further, in the above step S106, the condition that the indoor temperature reaches the preset temperature is that, when the changing direction of the indoor temperature approaches the preset temperature, the temperature difference between the indoor temperature and the preset temperature is smaller than the first preset temperature difference.
In the above step S112, the condition that the indoor temperature deviates from the preset temperature is that a temperature difference between the indoor temperature and the preset temperature is greater than the second preset temperature difference when the direction of change of the indoor temperature deviates from the preset temperature.
Specifically, the first preset temperature difference and the second preset temperature difference may be set according to the user's requirement, for example, the first preset temperature difference may be 0.5 ℃, 0.7 ℃, 0.9 ℃ or the like, and the second preset temperature difference may be 1 ℃, 1.5 ℃, 2 ℃ or the like.
Fig. 7 is a schematic flowchart of a control method of the on-hook 1 in the air conditioner room according to one embodiment of the present invention. Referring to fig. 7, the control method of the on-hook 1 in the air conditioner room further includes:
step S100, starting an air conditioner indoor wall-mounted unit 1, and setting a refrigerating or heating temperature;
step S102, starting a high-speed air supply mode;

Further, the air conditioner indoor wall mount 1 has a temperature detection device to detect an indoor temperature. When the air conditioner indoor wall-mounted unit 1 is started, firstly, whether the difference value between the indoor temperature and the preset temperature is larger than a third preset temperature difference is detected. If so, the high-speed air supply mode is started, i.e., step S102, and the steps in the control method are sequentially executed. If not, the micro-hole blowing mode is started, that is, step S108, and other steps in the control method are sequentially executed. Specifically, the third preset temperature difference may be set according to the user's requirement, so as to meet the use of users with different requirements.
Further, in the operation process of the air conditioner indoor wall-mounted unit 1, the control method further comprises the step of detecting whether the air conditioner indoor wall-mounted unit 1 receives an instruction for changing the air supply mode. If so, changing the current air supply mode; if not, the current air supply mode is kept. That is, when the air conditioner indoor wall unit 1 receives the air supply change command, the air supply mode is immediately changed according to the received command regardless of whether the indoor temperature has reached the preset temperature.
In the above control method, the start of the micro-hole air supply mode may refer to switching to the micro-hole air supply mode when the current air supply mode is the high speed or other air supply modes, or may refer to continuing to maintain the micro-hole air supply mode when the current air supply mode is the micro-hole air supply mode. Correspondingly, the high-speed air supply mode can be switched to the high-speed air supply mode when the current mode is the micropore or other air supply modes, and can also be continuously maintained when the current mode is the high-speed air supply mode.
