Detailed Description

Fig. 1 is a schematic side 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 exchanging device 60 are disposed inside the first chamber 100, and a first air inlet 101 is disposed at the top of the first chamber 100 to allow natural air to flow into the first chamber 100 from the first air inlet 101 and to flow through the heat exchanging device 60 to form heat exchanging air. 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 heat exchange 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 disposed at the front side of the first chamber 100, and is configured such that the bottom end thereof is communicated with the air outlet duct 300, so as to allow the heat exchange air of the first chamber 100 to flow into the second chamber 200 through the air outlet duct 300. That is, the second chamber 200 may communicate 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 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. 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.

Further, the top of the second chamber 200 is provided with a second intake vent 102 that can be controlled to open. Specifically, the panel 40 may be configured to rotatably open the second intake vent 102 forward. The second inlet 102 is configured to allow natural air in the surrounding environment to flow into the second chamber 200 from the second inlet 102, and flow into the outlet duct 300 and flow out of the outlet 201 after forming mixed air with the heat exchange air from the first chamber 100. That is, when the second intake vent 102 is controlled to be opened, natural air in the surrounding environment may enter the second chamber 200 and flow into the air outlet duct 300 communicated with the second chamber 200. Therefore, the natural air can be mixed with the heat exchange air flowing into the air outlet duct 300 from the first chamber 100 in the air outlet duct 300 to form mixed air, and then the mixed air is guided by the air outlet duct 300 to flow out of the casing.

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 indoor unit of the air conditioner can provide cold energy at least equal to that of the traditional air conditioner in the same working time while ensuring no wind blowing, and therefore, the indoor wall-mounted unit 1 of the air conditioner can be applied to a larger space.

Furthermore, the second air inlet 102 is formed in the air-conditioning indoor wall-mounted unit 1 to introduce natural air, and the natural air is mixed with heat exchange air in the air outlet duct 300, so that the air-conditioning indoor unit has large integral air quantity and air speed, the requirement of indoor integral refrigerating capacity is met on the premise of ensuring the comfort degree of a user, the indoor temperature balance is ensured, and the refrigerating/heating efficiency and the refrigerating/heating effect of the air-conditioning indoor unit are improved.

Fig. 2 is a schematic side view of the hanging device 1 for an air conditioner room according to an 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, when the air deflector 10 opens the air outlet 201, the second air inlet 102 is also controlled to be opened, so that the air in the surrounding environment flows into the air outlet duct 300 through the second chamber 200 to form mixed air with the heat exchange air. At this time, the natural air flowing into the outlet duct 300 through the second chamber 200 and the heat exchange air flowing into the outlet duct 300 through the first chamber 100 are mixed to form soft mixed air, so that the indoor unit of the air conditioner has large overall air volume and air speed, and the requirement of the indoor overall refrigerating capacity is met.

When the air deflector 10 closes the air outlet 201, the second air inlet 102 is also controlled to close, so that the air in the first chamber flows into the second chamber 200 through the air outlet duct 300 and flows out from the plurality of air holes 301. At this time, the heat exchange air in the first chamber 100 may flow in from the air outlet duct 300 and fill the second chamber 200, so as to further flow out from the plurality of air holes 301 opened on the front surface of the second chamber 200 in a dispersed manner.

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 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 in a transverse direction, and is configured to extend from a position on a rear upper side in the first chamber 100 to a position close to a rear side of the housing 30, and then extend downward to cover a lower side of the air inlet in a front-rear direction, thereby achieving heat exchange of almost all air flowing from the air inlet into the first chamber 100. The transverse partition 50 may be configured such that its upper end extends to the front end of the air intake and its lower end extends to the underside of the heat exchange unit 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 flowing into the second chamber 200 through or around 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 present invention, the plurality of vent holes 301 are divided into a plurality of rows of vent hole 301 groups in a transverse direction of the panel 40 with an equal inter-group interval between every two adjacent rows of vent hole 301 groups.

Fig. 4 is a schematic front view of an on-hook of an indoor unit of an air conditioner according to another embodiment of the present invention. Referring to fig. 4, in some embodiments of the present invention, 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 guide plate 10 is completely closed and blows air only through the plurality of ventilation holes 301, and a mixed blowing mode in which the air guide plate 10 is completely opened to blow mixed air. That is, when the air deflector 10 closes the air outlet 201, the second air inlet 102 is controlled to be closed, and at this time, the air conditioner indoor wall mounting machine 1 operates in the micro-hole air supply mode, and when the air deflector 10 opens the air outlet 201, the second air inlet 102 is controlled to be opened, and at this time, the air conditioner indoor wall mounting machine 1 operates in the mixed air supply mode.

Fig. 6 is a schematic diagram of a method for controlling an on-hook of an indoor unit of an air conditioner according to an embodiment of the present invention. Referring to fig. 6, the method for controlling an on-hook of an indoor wall of an air conditioner includes:

step S106, detecting whether the indoor temperature reaches a preset temperature or not when the on-hook operation of the indoor wall of the air conditioner is performed;

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 flow chart of a control method of an indoor wall-mounted unit of an air conditioner according to an embodiment of the present invention. Referring to fig. 7, the method for controlling an indoor wall-mounted unit of an air conditioner further includes:

Further, the wall-mounted unit of the air conditioner room is provided with a temperature detection device for detecting the indoor temperature. When the on-hook machine of the indoor wall of the air conditioner is started, whether the difference value between the indoor temperature and the preset temperature is larger than a third preset temperature difference or not is detected. If yes, the hybrid blowing 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 running process of the wall-mounted unit in the air conditioner room, the control method also comprises the step of detecting whether the wall-mounted unit in the air conditioner room 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-mounted unit receives the air supply change instruction, the air supply mode is immediately changed according to the received instruction regardless of whether the indoor temperature reaches the preset temperature.
