And R1, R2 and R3 satisfy the following relationships: 4 × (R2+ R3) < R1.
Through a plurality of tests of the inventor, the rotating speed of the cross-flow fan 200 is in the range of 600r/min to 1000r/min, and when the shape of the flange 710 meets the conditions, the coanda effect can be generated. The Coanda Effect (Coanda Effect), also known as Coanda Effect or Coanda Effect, refers to the tendency of a fluid (water or gas stream) to flow along a convex object surface instead of moving away from the original direction of flow. When there is surface friction (also called fluid viscosity) between the fluid and the surface of the object over which it flows, the fluid follows the surface of the object as long as the curvature is not large. Therefore, the flange 710 at the air outlet 113 can change the flow direction of the outlet airflow, that is, the outlet airflow flows along the flange 710 and is not directly blown onto the air conditioner decorative plate, thereby effectively avoiding the problem of condensation on the air conditioner decorative plate.
In fig. 9, the second vertical swing blade assembly 400 swings to have the air outlet direction facing the left side of the air conditioner, and for the user facing the air conditioner, the air outlet direction is facing the right side of the user. When the user is at the left side of the air conditioner, the user can enjoy a sense of no wind. In fig. 10, the second vertical swing blade assembly 400 swings to have the air outlet direction facing the right side of the air conditioner, and for the user facing the air conditioner, the air outlet direction is towards the left side of the user. When the user is at the right side of the air conditioner, the user can enjoy a sense of no wind. The air outlet directions of the first vertical oscillating blade assembly 300 in fig. 9 and 10 are both right ahead.
As shown in fig. 11, the air supply control device 800 of the air conditioner of the present embodiment includes: a detection module 801, a judgment module 802 and a driving module 803. The detection module 801 may be configured to detect an input operation of a user. The determining module 802 may be configured to determine whether the no-wind-sensing signal is received for the first time according to the input operation. The driving module 803 may be configured to drive the horizontal oscillating blade assembly 500 to swing to an upward direction of the air outlet direction and form a predetermined angle with the horizontal direction when the non-wind-sensing signal is received for the first time, and drive the second vertical oscillating blade assembly 400 to swing to an arbitrary side of the air outlet direction facing the left and right sides of the air conditioner. In a preferred embodiment, the preset angle between the upward air outlet direction of the yaw blade assembly 500 and the horizontal direction may be 60 °, which can ensure that the air outlet of the yaw blade assembly 500 does not directly blow to the user, and that the air outlet does not excessively go upward to cause cold loss. The specific values of the preset angle are only exemplary and are not intended to limit the present invention. In other embodiments, the preset angle may be set to other values according to actual conditions.
The input operation of the user can be acquired through a remote controller of the air conditioner or a touch screen of the air conditioner. The air-out direction of yaw leaf subassembly 500 upwards and be preset the angle with the horizontal direction, and this specific numerical value of presetting the angle can set up according to actual conditions, avoids the air-out direction of yaw leaf subassembly 500 to be the dead ahead directly blowing user. The second vertical swing blade assembly 400 swings to any side of the air outlet direction facing the left side and the right side of the air conditioner, that is, the second vertical swing blade assembly 400 can swing to the left side of the air conditioner or swing to the right side of the air conditioner. It should be noted that, the air conditioners in the embodiments of the present invention are all referred to as air conditioner indoor units. Also, in a preferred embodiment, the air conditioner in the embodiment of the present invention may be a floor air conditioner indoor unit.
The air conditioner of this embodiment utilizes the characteristics that cold air density is big easily to sink, and hot air density is little easily to rise, when receiving no wind sense signal for the first time, adjusts the air-out direction that can directly blow user's horizontal swing blade subassembly 500 and the second vertical swing blade subassembly 400 of below, can make the air conditioner realize no wind sense effect. Meanwhile, the refrigeration effect of the air conditioner is considered, the normal air outlet of each swing blade assembly is guaranteed, and air volume loss caused by pursuing no wind sense is avoided. On the basis of meeting the requirement of a user on cold air, the user has no feeling of wind, and various uncomfortable symptoms caused by direct blowing of the air conditioner are avoided.
Fig. 12 is a schematic block diagram of an air supply control apparatus 800 of an air conditioner according to another embodiment of the present invention. In addition to the above embodiment, the air supply control device 800 of the air conditioner may further include: an adjustment module 804.
Wherein the adjustment module 804 may be configured to adjust the operating wind speed of the fan of the crossflow blower 200 to a low speed after the yaw blade assembly 500 and the second vertical swing blade assembly 400 swing to the respective directions, wherein the operating wind speed comprises: high speed, medium speed and low speed. The adjusting module 804 adjusts the running wind speed of the fan, and the running wind speed is matched with the wind outlet directions of the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400, so that the realization effect of no wind sensation is effectively guaranteed. Crossflow blower 200 may include a fan and a fan motor for driving the fan in motion, the operating speed of the fan being varied by varying relevant operating parameters of the fan motor.
In addition, the determining module 802 of the present embodiment may be further configured to: and judging whether the no-wind-sense signal is received for the second time after the running wind speed of the air conditioner is adjusted to be low. The drive module 803 may also be configured to: when the no-wind-sense signal is received for the second time, the second vertical swing blade assembly 400 is driven to swing to the other side of the left side and the right side of the air conditioner facing the air outlet direction.
That is, if the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the left side of the air conditioner when the non-wind-sensing signal is received for the first time, the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the right side of the air conditioner when the non-wind-sensing signal is received for the second time. Because the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction faces the left side of the air conditioner, the non-wind-feeling signal can still be received for the second time, which indicates that no wind feeling is realized by the user, and the air outlet direction of the second vertical oscillating blade assembly 400 needs to be adjusted to the opposite direction.
If the non-wind-sensing signal is received for the first time, the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the right side of the air conditioner, and if the non-wind-sensing signal is received for the second time, the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the left side of the air conditioner. Because the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction faces the right side of the air conditioner, the non-wind-feeling signal can be still received for the second time, which indicates that no wind feeling is realized by the user, and the air outlet direction of the second vertical oscillating blade assembly 400 needs to be adjusted to the opposite direction.
The determination module 802 may be further configured to: after the second vertical swing blade assembly 400 is driven to swing to the other side of the left and right sides of the air conditioner, whether the no-wind-sense signal is received for the third time is judged. The drive module 803 may also be configured to: when the no-wind-feeling signal is received for the third time, the yaw blade assembly 500 and the second yaw blade assembly 400 are driven to be reset to the positions before the no-wind-feeling signal is received for the first time, and the fan is adjusted to the operating wind speed before the no-wind-feeling signal is received for the first time. After the no-wind-sense signal is received for the third time, the user can be considered to be no longer in need of no wind sense, and the air conditioner can exit the no-wind-sense mode.
It should be noted that, when it is determined that the no-wind-sensation signal is not received for the first time, the no-wind-sensation signal is not received for the second time, or the no-wind-sensation signal is not received for the third time according to the input operation, the horizontal pendulum blade assembly 500 and the second vertical pendulum blade assembly 400 are kept unchanged in the current air outlet direction. The no-wind-feeling signal is not continuously received, which indicates that the user is satisfied with the overall operation state of the current air conditioner, so that no change is needed, and the air outlet directions of the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 are maintained. The fan can also maintain the current operating wind speed in the above case.
Since the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 can blow the user directly, the air supply control device of the air conditioner controls the air outlet directions of the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 under different conditions. In addition, the air outlet direction of the first vertical oscillating blade assembly 300 can be determined according to input operation, and the first vertical oscillating blade assembly 300 can be driven to swing to the air outlet direction determined by the air outlet direction orientation. That is to say, the air outlet direction of the first vertical oscillating blade assembly 300 is not affected by the received no-wind-sense signal, and can directly swing according to the air outlet direction input by the user.
The air conditioner of this embodiment all can satisfy user's actual demand under the various condition, promotes the refrigeration effect of air conditioner. In addition, the first and second vertical swing vane assemblies 300 and 400 of the air conditioner may be separately controlled. The air conditioner can supply air to different directions at the same time, and the diversity of air supply modes of the air conditioner is improved. It should be noted that, since the yaw blade assembly 500 includes: a vertical link 510, a plurality of yaw vanes 520, and a first motor 530. The wind outlet direction of the yaw blade assembly 500 mentioned above actually refers to the wind outlet direction of the plurality of yaw blades 520. The first vertical pendulum blade assembly 300 includes: a first air-out frame 310, a plurality of first vertical swinging blades 320 and a second motor 330. The air outlet direction of the first vertical oscillating blade assembly 300 mentioned above actually refers to the air outlet direction of the plurality of first vertical oscillating blades 320. The second vertical swing blade assembly 400 includes: a second air-out frame 410, a plurality of second vertical swinging blades 420 and a third motor 430. The air outlet direction of the second vertical swing blade assembly 400 mentioned above actually refers to the air outlet direction of the plurality of second vertical swing blades 420.
The embodiment also provides an air supply control method of the air conditioner, which is suitable for the air conditioner of any embodiment. Fig. 13 is a schematic view of a blowing control method of an air conditioner according to an embodiment of the present invention. The air supply control method of the air conditioner sequentially executes the following steps:
step S1302, detecting an input operation of a user;
step S1304, judging whether the no-wind-feeling signal is received for the first time, if so, executing step S1306, otherwise, returning to execute step S1302;
in step S1306, the horizontal oscillating blade assembly 500 of the air conditioner is driven to swing to the upward direction of the air outlet and form a preset angle with the horizontal direction, and the second vertical oscillating blade assembly 400 is driven to swing to the position where the air outlet direction faces to any one of the left side and the right side of the air conditioner.
The input operation of the user in step S1302 may be acquired through a remote controller of the air conditioner or a touch screen of the air conditioner. Whether the no-wind-feeling signal is received for the first time in step S1304 is determined by the user' S input operation in step S1302. In addition, the frequency of receiving the non-wind-sensing signal can be recorded, so that the air outlet direction of each swing blade assembly can be adjusted conveniently according to the frequency.
In step S1306, the air outlet direction of the horizontal blade assembly 500 is upward and forms a preset angle with the horizontal direction, and the specific value of the preset angle can be set according to actual conditions, so that the air outlet direction of the horizontal blade assembly 500 is prevented from being a direct-blowing user right ahead. The second vertical swing blade assembly 400 swings to any side of the air outlet direction facing the left side and the right side of the air conditioner, that is, the second vertical swing blade assembly 400 can swing to the left side of the air conditioner or swing to the right side of the air conditioner.
According to the air supply control method of the air conditioner, by utilizing the characteristics that the cold air density is large and easy to sink, and the hot air density is small and easy to rise, when the no-wind-sensation signal is received for the first time, the air outlet directions of the horizontal swing blade assembly 500 capable of directly blowing the air to the user and the second vertical swing blade assembly 400 below the horizontal swing blade assembly are adjusted, so that the no-wind-sensation effect of the air conditioner can be realized. Meanwhile, the refrigeration effect of the air conditioner is considered, the normal air outlet of each swing blade assembly is guaranteed, and air volume loss caused by pursuing no wind sense is avoided. On the basis of meeting the requirement of a user on cold air, the user has no feeling of wind, and various uncomfortable symptoms caused by direct blowing of the air conditioner are avoided.
In some optional embodiments, the air conditioner may achieve a higher technical effect by further optimizing and configuring the above steps, and the following describes in detail the air supply control method of the air conditioner of this embodiment in combination with a description of an optional execution flow of this embodiment, where this embodiment is merely an illustration of the execution flow, and in a specific implementation, an execution sequence and an operation condition of a part of steps may be modified according to specific implementation requirements. Fig. 14 is a detailed flowchart of a blowing control method of an air conditioner according to an embodiment of the present invention. As shown in fig. 14, the air supply control method of the air conditioner of the present embodiment includes the steps of:
step S1402, detecting an input operation by a user;
step S1404, determining whether the no-wind-feeling signal is received for the first time, if yes, performing step S1406, and if no, performing step S1418;
step S1406, the horizontal oscillating vane assembly 500 of the air conditioner is driven to swing to the upward direction of the air outlet direction and form a preset angle with the horizontal direction, and the second vertical oscillating vane assembly 400 is driven to swing to the air outlet direction facing to any side of the left and right sides of the air conditioner;
step S1408, adjusting the operating speed of the fan of the crossflow blower 200 to a low speed;
step S1410, determining whether the no-wind-feeling signal is received for the second time, if yes, performing step S1412, and if no, performing step S1418;
step S1412, driving the second vertical swing blade assembly 400 to swing to the other side of the air outlet direction facing the left and right sides of the air conditioner;
step S1414, determining whether the no-wind-feeling signal is received for the third time, if yes, performing step S1416, and if not, performing step S1418;
step S1416, the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 of the air conditioner are driven to be reset to the positions before the non-wind-sensing signal is received for the first time, and the fan is adjusted to the operation wind speed before the non-wind-sensing signal is received for the first time;
in step S1418, the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 are kept unchanged in the current air outlet direction.
In step S1408, the operating wind speed of the fan of the cross-flow fan 200 is adjusted to be matched with the wind outlet directions of the horizontal oscillating blade assembly 500 and the second vertical oscillating blade assembly 400, so that the realization effect of no wind sensation is effectively ensured. Step S1406 is to drive the second vertical swing blade assembly 400 to swing to an air outlet direction facing to any side of the left and right sides of the air conditioner on the premise of receiving the no-wind-sense signal for the first time; in step S1412, on the premise of receiving the no-wind-sense signal for the second time, the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction thereof faces the other side of the left and right sides of the air conditioner.
That is, if the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the left side of the air conditioner when the non-wind-sensing signal is received for the first time, the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the right side of the air conditioner when the non-wind-sensing signal is received for the second time. Because the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction faces the left side of the air conditioner, the non-wind-feeling signal can still be received for the second time, which indicates that no wind feeling is realized by the user, and the air outlet direction of the second vertical oscillating blade assembly 400 needs to be adjusted to the opposite direction.
If the non-wind-sensing signal is received for the first time, the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the right side of the air conditioner, and if the non-wind-sensing signal is received for the second time, the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction of the second vertical oscillating blade assembly faces the left side of the air conditioner. Because the second vertical oscillating blade assembly 400 is driven to oscillate until the air outlet direction faces the right side of the air conditioner, the non-wind-feeling signal can be still received for the second time, which indicates that no wind feeling is realized by the user, and the air outlet direction of the second vertical oscillating blade assembly 400 needs to be adjusted to the opposite direction.
After the no-wind-feeling signal is received for the third time in step S1414, it may be considered that the user does not need no wind feeling any more, and the air conditioner may exit the no-wind-feeling mode, so as to execute step S1416: the yaw blade assembly 500 and the second yaw blade assembly 400 are driven to reset to a position before the non-wind-sensing signal is received for the first time, and the fan is adjusted to an operating wind speed before the non-wind-sensing signal is received for the first time.
It should be noted that, when it is determined that the no-wind-feeling signal is not received for the first time, the no-wind-feeling signal is not received for the second time, or the no-wind-feeling signal is not received for the third time according to the input operation, step S1418 is executed: the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 keep the current air outlet direction unchanged. The no-wind-feeling signal is not continuously received, which indicates that the user is satisfied with the overall operation state of the current air conditioner, so that no change is needed, and the air outlet directions of the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 are maintained. The fan can also maintain the current operating wind speed in the above case.
Since the yaw blade assembly 500 and the second yaw blade assembly 400 can blow the user directly, the above air supply control method of the air conditioner controls the air outlet directions of the yaw blade assembly 500 and the second yaw blade assembly 400 under different conditions. In addition, the air outlet direction of the first vertical oscillating blade assembly 300 can be determined according to input operation, and the first vertical oscillating blade assembly 300 can be driven to swing to the air outlet direction determined by the air outlet direction orientation. That is to say, the air outlet direction of the first vertical oscillating blade assembly 300 is not affected by the received no-wind-sense signal, and can directly swing according to the air outlet direction input by the user.
The inventor finds that through multiple experiments, the air supply control method of the air conditioner performs combined control on the air outlet directions of the horizontal swing blade assembly 500 and the second vertical swing blade assembly 400 when receiving a no-wind-sensation signal, can achieve no wind feeling when the user stands in front of the air conditioner, and can ensure that the air volume loss is small, thereby ensuring the refrigeration effect. And CAE (Computer Aided Engineering) simulation is carried out on the swing air outflow field analysis-speed streamline and the swing air outflow field analysis-temperature section, analysis and verification show that the air quantity loss is small, and the indoor cross section temperature distribution is relatively uniform.
In the air supply control method of the air conditioner of this embodiment, whether the no-wind-sensation signal is received for the first time is determined by detecting the input operation of the user, and if so, the horizontal oscillating vane assembly 500 is driven to swing to the upward direction of the air outlet direction and form a preset angle with the horizontal direction, and the second vertical oscillating vane assembly 400 is driven to swing to the direction of the air outlet direction towards any side of the left side and the right side of the air conditioner. Because the cold air density is high and easy to sink, and the hot air density is low and easy to rise, when a no-wind-sense signal is received for the first time, the air outlet directions of the horizontal swing blade assembly 500 capable of directly blowing the user and the second vertical swing blade assembly 400 below the horizontal swing blade assembly are adjusted, so that the no-wind-sense effect of the air conditioner can be realized. Meanwhile, the refrigeration effect of the air conditioner is considered, the normal air outlet of each swing blade assembly is guaranteed, and air volume loss caused by pursuing no wind sense is avoided. On the basis of meeting the requirement of a user on cold air, the user has no feeling of wind, and various uncomfortable symptoms caused by direct blowing of the air conditioner are avoided.
Further, in the air supply control method of the air conditioner of the embodiment, after the traverse vane assembly 500 and the second vertical vane assembly 400 are driven to swing to the corresponding directions, the operating air speed of the fan of the cross flow fan 200 is adjusted to be a low speed, so that the realization effect of no wind sensation is effectively ensured. And after receiving the no-wind-sense signal for the second time, the second vertical swing blade assembly 400 is driven to swing to the other side of the air outlet direction facing the left side and the right side of the air conditioner, so that the situation that the direction of the second vertical swing blade assembly 400 is adjusted to be the side where the user is located after receiving the no-wind-sense signal for the first time is avoided, and the user can be further ensured to feel no wind. After receiving the no-wind-sensing signal for the third time, the driving yaw blade assembly 500 and the second yaw blade assembly 400 are reset to the positions before receiving the no-wind-sensing signal for the first time, and the fan is adjusted to the operating wind speed before receiving the no-wind-sensing signal for the first time. Namely, the working state of the air conditioner is automatically adjusted when the user has no demand of no wind feeling. The actual requirements of users can be met under various conditions, and the refrigeration effect of the air conditioner is improved. In addition, the first and second vertical swing vane assemblies 300 and 400 of the air conditioner may be separately controlled. The air conditioner can supply air to different directions at the same time, and the diversity of air supply modes of the air conditioner is improved.
