Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly provides an air deflector device, an air conditioner and a control method thereof. Background Art

[0002] At present, most of the wall-mounted air conditioners on the market adopt the design of a single large air deflector for commutation or the coordinated linkage of two air deflectors for up and down air guiding. To a certain extent, these two designs meet the air supply needs of users, but the singularity of their rotation methods limits the diversity and flexibility of the air supply of the air conditioner.

[0003] Although the design of a single large air deflector is simple, it can only achieve limited air direction adjustment and is difficult to meet the diverse needs of users for air supply angles. The coordinated linkage of two air deflectors for up and down air guiding, although improving this problem to a certain extent by realizing up and down air guiding through the synchronous movement of the two air deflectors, still limits the innovation of the air supply mode due to its synchronous linkage characteristics.

[0004] Whether it is a single air deflector or two air deflectors, their movement trajectories and air supply modes are relatively fixed and it is difficult to flexibly adjust according to the actual needs of users or environmental conditions.

[0005] In summary, the existing air deflector devices of air conditioners have fewer air supply modes and are difficult to meet the needs of users.

[0006] Correspondingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0040] The following describes the preferred implementation manners of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0041] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "front", "rear", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance;

[0042] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "communicated with" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] First, refer to Figure 1 , the air guiding device of the present invention includes a main board 10, a first flap 12 and a second flap 11; both the first flap 12 and the second flap 11 are connected to the main board 10 in a rotatable manner, and the first flap 12 and the second flap 11 are located on opposite sides of the main board 10. By providing two rotatable flaps on opposite sides of the main board 10, the present invention can achieve different combined air supply modes, improving the diversity and flexibility of air supply.

[0044] Refer to Figure 2 and Figure 3 , taking the second flap 11 as an example to illustrate the rotatable connection manner between the two flaps and the main board. Specifically, rotating shafts 112 are provided at both ends of the second flap 11, and first rotation holes 104 and second rotation holes 105 are provided at both ends of the main board 10 in the length direction. The two rotating shafts 112 are respectively inserted into the first rotation hole 104 and the second rotation hole 105 and fixedly connected to the second flap 11. The rotating shafts 112 can rotate relative to the first rotation hole 104 and the second rotation hole 105 to achieve the relative rotation of the second flap 11 and the main board 10.

[0045] Of course, the above-mentioned rotatable connection manner is only a preferred setting manner. It can also be that a third rotation hole (not shown in the figure) is provided on the second flap 11, a sliding groove is provided in the third rotation hole, the sliding groove penetrates the second flap 11 along the axial direction of the third rotation hole, a rotating shaft sequentially passes through the first rotation hole 104, the third rotation hole and the second rotation hole 105, and a slider or a slide bar is provided at a position corresponding to the third rotation hole on the rotating shaft. The positions of the rotating shaft corresponding to the first rotation hole 104 and the second rotation hole 105 are smooth columnar structures, and the slider and the sliding groove are matched to realize the rotation of the rotating shaft and drive the second flap 11 to rotate.

[0046] The rotatable connection manner between the first flap 12 and the main board 10 is the same as that of the second flap 11, and will not be elaborated here.

[0047] Refer to Figure 1 and Figure 3, a plurality of first ventilation holes 121 are provided on the first flap 12, and a plurality of second ventilation holes 111 are provided on the second flap 11. The plurality of first ventilation holes 121 and the plurality of second ventilation holes 111 correspond to each other one by one. The first ventilation holes 121 and the second ventilation holes 111 are the same and are both strip-shaped. When the first flap 12 and the second flap 11 are erected or form an inclined angle with the main board 10, when the wind passes through the plurality of second ventilation holes 111 and the plurality of first ventilation holes 121, the wind can be stratified.

[0048] In other embodiments, the plurality of first ventilation holes 121 and the plurality of second ventilation holes 111 do not correspond to each other one by one.

[0049] Refer to Figure 1 and Figure 2 , a first receiving groove 102 is provided on the main board 10, and the first flap 12 can be rotated into the first receiving groove 102 and received by the first receiving groove 102; a second receiving groove 101 is provided on the main board 10, and the second flap 11 can be rotated into the second receiving groove 101 and received by the second receiving groove 101. Based on this, when the first flap 12 is in the received state, the upper surface of the first flap 12 can be continuously flush with the upper surface of the main board 10, and the upper surface of the second flap 11 can be continuously flush with the upper surface of the main board 10, reducing the resistance when the air guiding device only uses the main board 10 to guide the air. Of course, this is not restrictive. It can also be that only one of the first receiving groove 102 and the second receiving groove 101 is provided, and those skilled in the art can set it according to the actual situation.

[0050] Next, refer to Figure 2 , 4 to 6, the air conditioner of the present invention includes a housing 2, an air outlet 21 is formed on the housing 2, a blower 23 and an air duct 22 are provided inside the housing 2, the wind driven by the blower 23 passes through the air duct 22 and is blown out from the air outlet 21. The air conditioner further includes the air guiding device in any of the above embodiments. The air guiding device is provided at the air outlet 21. Specifically, a plurality of first connecting portions 103 are provided on the main board 10, and a second connecting portion 26 is provided below the top 24 of the air outlet. The first connecting portion 103 and the second connecting portion 26 are connected in a rotatable manner. The two sides in the length direction of the main board 10 are connected to the two sides in the length direction of the air outlet 21 in a rotatable manner, and the air conditioner includes a first driving motor (not shown in the figure), and the first driving motor is used to drive the main board 10 to rotate.

[0051] The air conditioner or the air guiding device further includes: a second driving motor (not shown in the figure) and a third driving motor (not shown in the figure). The second driving motor is used to drive the first flap 12 to rotate, and can stop at a set position or swing back and forth. The third driving motor is used to drive the second flap 11, and can stop at a set position or swing back and forth. The first driving motor can be fixed on the main board 10, and its driving shaft is connected to the rotating shaft of the first flap 12. The second driving motor can also be fixed on the fixed main board 10, and its driving shaft is connected to the rotating shaft 112 of the second flap 11.

[0052] Refer to Figure 6 , Figure 6 In [reference], the first driving motor drives the main board 10 to rotate to the first position. When the main board 10 is in the first position, the air at the air outlet 21 blows forward and downward. The second driving motor drives the first flap 12 to unfold, that is, to rotate to a position parallel to the main board 10. It can be understood that the upper surface of the first flap 12 and the upper surface of the main board 10 are in the same plane. At this time, the first flap 12 extends the air supply length of the main board 10, plays a role in extending the air supply duct, and improves the air volume.

[0053] Refer to Figure 7 , Figure 7 In [reference], the first driving motor drives the main board 10 to rotate to the first position, and the second driving motor drives the first flap 12 to rotate to a first preset angle with the main board 10. The first preset angle is an acute angle. Specifically, it is the included angle between the intersection line of the lower surface of the first flap 12 (the lower surface when the first flap 12 is in the left - right horizontal state) and the lower surface of the main board 10 (the lower surface when the main board is in the left - right horizontal state) along the air outlet direction. At this time, the first flap 12 tends to be in a horizontal state or is in a horizontal state, which can avoid the air blowing directly at the user. It can also be to rotate the first flap 12 to an upward - inclined state to lift the air.

[0054] The first preset angle can be 30°, 40°, 45°, 50° or 60°, or other degrees. Those skilled in the art can set it according to the inclination state of the main board 10 by themselves, as long as it can achieve the effect of preventing the air from blowing directly.

[0055] Refer to Figure 8 , Figure 8 In [reference], the first driving motor drives the main board 10 to rotate to the second position. The second position is the anti - direct - blowing position. When the main board 10 is in the anti - direct - blowing position, the main board 10 tends to be in a horizontal state or is in a horizontal state, so that the air at the air outlet 21 blows forward, avoiding blowing directly at the user. The second driving motor drives the first flap 12 to rotate to a position parallel to the main board 10. It can be understood that the upper surface of the first flap 12 and the upper surface of the main board 10 are in the same plane. At this time, the first flap 12 extends the air supply length of the main board 10, plays a role in extending the air supply duct, and improves the air volume.

[0056] Refer to Figure 9 , Figure 9 In [[reference document]], the first driving motor drives the main board 10 to rotate to the second position, the second driving motor drives the first flap 12 to rotate to a position at a first preset angle with the main board 10. The first preset angle is the included angle of the intersection line of the lower surface of the first flap 12 (the lower surface when the first flap 12 is in the left - right horizontal state) and the lower surface of the main board 10 (the lower surface when the main board is in the left - right horizontal state) along the air - outlet wind direction. The third driving motor drives the second flap 11 to rotate to a position at a second preset angle with the main board 10. The second preset angle is the included angle of the intersection line of the lower surface of the second flap 11 (the lower surface when the second flap 11 is in the left - right horizontal state) and the lower surface of the main board 10 (the lower surface when the main board is in the left - right horizontal state) along the air - outlet wind direction. The first preset angle can be the same as the second preset angle. As shown in [[figure reference]], both flaps are in the upward - tilted state, which can better prevent direct blowing. Further, the first flap 12 and the second flap 11 are in the vertical or inclined state, and the first ventilation holes 121 on the first flap 12 and the second ventilation holes 111 on the second flap 11 can play a role in stratifying the air to better prevent direct blowing. Figure 9 The second preset angle can be 30°, 40°, 45°, 50° or 60°, or other degrees. It can be the same as or different from the first preset angle. Those skilled in the art can set it according to the inclination state of the main board 10 as long as it can achieve the effect of preventing the air from blowing directly.

[0057] Refer to [[another reference document]]. In it, the first driving motor drives the main board 10 to rotate to the third position. When the main board 10 is in the third position, the air outlet 21 blows downward. The second driving motor drives the first flap 12 to rotate to a position parallel to the main board 10, and the third driving motor drives the second flap 11 to rotate to a position parallel to the main board 10. A bending part 25 is connected to the top of the air outlet 24. When the main board 10 rotates to the position as shown in [[figure reference]], the second flap 11 abuts against the bending part 25, closing the upper half of the air outlet 21. In this way, the second flap 11 can be unfolded first, and then the main board 10 is controlled to rotate to the third position. The second flap 11 abuts against the bending part 25, resulting in two parts of the air outlet 21, and only the lower air outlet 21 can blow air, directly blowing to the ground, which is suitable for the heating mode and can achieve the effect of heating the room fastest.

[0058] Refer to Figure 10 , Figure 10 Of course, this is not restrictive. In order not to limit the rotation of the second flap 11, refer to [[reference document]] and [[another reference document]] Figure 10 When the main board 10 rotates to the position as shown in [[figure reference]], the second flap 11 abuts against the bending part 25, closing the upper half of the air outlet 21. In this way, the second flap 11 can be unfolded first, and then the main board 10 is controlled to rotate to the third position. The second flap 11 abuts against the bending part 25, resulting in two parts of the air outlet 21, and only the lower air outlet 21 can blow air, directly blowing to the ground, which is suitable for the heating mode and can achieve the effect of heating the room fastest.

[0059] Certainly, this is not restrictive. In order not to limit the rotation of the second flap 11, refer to [[reference document]] Figure 11 and Figure 12, a first avoidance portion 241 is provided at the top 24 of the air outlet, and a second avoidance portion 261 is provided on the second connection portion 26. The first avoidance portion 241 and the second avoidance portion 261 allow the second flap 11 to rotate. A blocking portion 242 is also provided at the first avoidance portion 241. In the air outlet direction of the air outlet 21, the blocking portion 242 is located upstream of the second flap 11. The second flap 11 can rotate to a position where it fits against the blocking portion 242, so as to achieve the effect of sealing the gap between the top 24 of the air outlet and the second flap 11. That is, when the wind blows against the second flap 11, due to the setting of the blocking portion, it will not reach the gap between the lower surface of the first avoidance portion 241 and the upper end of the second flap 11. In this setting method, the main board 10 can be first rotated to the third position, and then the second flap 11 can be rotated to a position parallel to the main board 10.

[0060] In some other embodiments, the second connection portion 26 may not be provided, and both ends of the main board 10 in the length direction are rotatably connected to both ends of the housing 2. That is to say, in the embodiments without the second connection portion 26, there is no need to provide the second avoidance portion 261.

[0061] In some other embodiments, the bending portion 25 is not provided, and only the top 24 of the air outlet, as well as the first avoidance portion 241 and the blocking portion 242 are provided.

[0062] In some other embodiments, the bending portion 25 is not provided, and the first avoidance portion 241 and the blocking portion 242 are not provided either. The overall size of the air guiding device is set such that when the main board 10 is first in the third position and then the second flap 11 is rotated, when the second flap 11 rotates to be parallel to the main board 10, it abuts against the top 24 of the air outlet.

[0063] The air conditioner of the present invention further includes a controller, and the controller can issue instructions to the first driving motor, the second driving motor, and the third driving motor to respectively control the main board 10, the first flap 12, and the second flap 11 to rotate to different positions, and the controller can control all operations of the air conditioner.

[0064] Next, refer to Figure 13 , the main steps of the control method of the present invention include:

[0065] Step S1: Obtain the indoor temperature;

[0066] Step S2: Calculate the absolute value of the difference between the indoor temperature and the target temperature;

[0067] Step S3: If the absolute value is less than or equal to the first preset value, control the first flap to rotate to a position at a first preset angle with respect to the main board;

[0068] Step S4: If the absolute value is greater than the first preset value, control the first flap to rotate to a position parallel to the main board.

[0069] In step S1, the indoor temperature can be obtained through an indoor temperature sensor, and then step S2 is executed to calculate the absolute value of the difference between the indoor temperature and the target temperature. The target temperature is the temperature set by the user or the most suitable temperature under the current condition automatically determined in a certain specific mode of the air conditioner.

[0070] In step S2, if the absolute value of the difference is less than or equal to the first preset value, when heating, the difference between the indoor temperature and the target temperature is greater than or equal to -3°C and less than 0°C, and when cooling, the difference between the indoor temperature and the target temperature is less than or equal to 3°C. This proves that the difference between the indoor temperature and the target temperature is small and the two are relatively close, so step S3 is executed to control the first flap 12 to rotate by a first preset angle. At this time, no matter what position the main board 10 is in, the first flap 12 can achieve the effect of preventing direct blowing.

[0071] In step S2, if the absolute value of the difference is greater than the first preset value, when heating, the difference between the indoor temperature and the target temperature is less than -3°C, and when cooling, the difference between the indoor temperature and the target temperature is greater than 3°C. This proves that the difference between the indoor temperature and the target temperature is large and a larger air supply volume is required to quickly adjust the indoor temperature. Therefore, step S4 is executed to control the first flap 12 to rotate to a position parallel to the main board 10 to achieve the maximum air supply effect.

[0072] In this preferred embodiment, in step S3, it also includes controlling the second flap 11 to be in a retracted state, and in step S4, it also includes controlling the second flap 11 to be in a retracted state.

[0073] In some other embodiments, in step S3, it also includes controlling the second flap 11 to rotate to a position at a second preset angle with respect to the main board 10, and in step S4, it also includes controlling the second flap 11 to rotate to a position parallel to the main board 10.

[0074] The first preset value is preferably 3°C. Of course, this is not restrictive and can also be 2°C or 4°C, or other values. Those skilled in the art can set it according to the actual situation.

[0075] Next, refer to FIG. 14. As Figure 14 shown, the detailed steps of a preferred embodiment of the control method of the air conditioner according to the present invention include:

[0076] Step S101: Obtain the indoor temperature;

[0077] Step S102: Calculate the absolute value of the difference between the indoor temperature and the target temperature;

[0078] Step S103: If the absolute value is less than or equal to the first preset value, control the first flap to rotate to a position at a first preset angle with respect to the main board;

[0079] Step S104: If the absolute value is greater than the first preset value, control the first flap to rotate to a position parallel to the main board;

[0080] Step S105: Obtain the operating mode of the air conditioner;

[0081] Step S106: If the air conditioner is in the target heating mode and the absolute value is greater than the first preset value, control the second flap to rotate to a position parallel to the main board;

[0082] Step S107: If the air conditioner is in the target heating mode, control the second flap to rotate to a position parallel to the main board. If the absolute value is less than or equal to the first preset value, control the first flap to swing back and forth within a preset range;

[0083] Step S108: If the air conditioner is in the anti-direct-blow mode, determine whether there is a user within a preset distance in front of the air conditioner outlet;

[0084] Step S109: Control the first flap to rotate to a position parallel to the main board;

[0085] Step S110: Control the first flap to rotate to a position at a first preset angle with respect to the main board, and control the second flap to rotate to a position at a second preset angle with respect to the main board.

[0086] Steps S101 to S104 are the same as steps S1 to S4, and will not be elaborated here;

[0087] Whether step S103 or step S104 is executed, step S105 is continued. In step S105, the operating modes of the air conditioner include the target cooling mode, the anti-direct-blow mode, and the target heating mode. The air conditioner can accept instructions issued by the user through the control panel or the control device. The user can select the target cooling mode, the anti-direct-blow mode, and the target heating mode by himself. After issuing the instruction, the controller of the air conditioner will receive the instruction. After receiving the instruction of the target cooling mode, it is default to obtain the operating mode of the air conditioner and control the air conditioner to enter the target cooling mode; after receiving the instruction of the anti-direct-blow mode, it is default to obtain the operating mode of the air conditioner and control the air conditioner to enter the anti-direct-blow mode; after receiving the instruction of the target heating mode, it is default to obtain the operating mode of the air conditioner and control the air conditioner to enter the target heating mode; the target cooling mode needs to control the main board 10 to move to the first position, the anti-direct-blow mode needs to control the main board 10 to move to the second position, and the target heating mode needs to control the main board 10 to move to the third position.

[0088] In step S105, if the operating mode of the air conditioner is the target cooling mode, that is, when an instruction to operate in the target cooling mode is received, the control main board 10 moves to the first position, and then returns to execute step S102; in the target cooling mode, if the absolute value is less than or equal to the first preset value, that is, the difference between the indoor temperature and the target temperature is less than or equal to 3°C, then the first flap 12 is controlled to rotate to a position at a first preset angle with respect to the main board 10, and the air guiding device is as shown in Figure 7 ; if the absolute value is greater than the first preset value, that is, the difference between the indoor temperature and the target temperature is greater than 3°C, the first flap 12 is controlled to rotate to a position parallel to the main board 10, and the air guiding device is as shown in Figure 6 ;

[0089] In step S103 or step S104, the second flap 11 is in the retracted state as shown in Figure 6 and Figure 7 , but this is not restrictive, and the second flap 11 can also be rotated to a position parallel to the main board 10.

[0090] In step S105, if the operating mode of the air conditioner is the target heating mode, that is, when an instruction to operate in the target heating mode is received, the control main board 10 moves to the third position. If step S105 is executed after step S103, then the absolute value of the difference is less than or equal to the first preset value, that is, the difference between the indoor temperature and the target temperature is greater than or equal to -3°C. Then, after step S105, step S107 is executed, the second flap 11 is controlled to rotate to a position parallel to the main board 10, and the first flap 12 is controlled to swing back and forth within a preset range. Since the temperature difference is small, it proves that the indoor temperature is close to the target temperature. Therefore, the control main board 10 moves to the third position, and the second flap 11 is controlled to rotate to a position parallel to the main board 10, so that the air directly reaches the ground, ensuring good heating effect. Also, combined with the back-and-forth swing of the first flap 12 within the preset range, it avoids direct blowing on the user and prevents dryness in the body feeling.

[0091] The position where the first flap 12 is parallel to the main board 10 is the starting position, and the position after the first flap 12 rotates counterclockwise by the target angle from the starting position is the end position. The preset range is that the second flap 11 swings back and forth between the starting position and the end position. The target angle is greater than 0° and less than 180°, and those skilled in the art can set it according to the actual situation.

[0092] In step S105, if the operating mode of the air conditioner is the target heating mode, and if step S105 is executed after step S104, then the absolute value of the difference is greater than the first preset value, that is, the difference between the indoor temperature and the target temperature is less than -3°C. Therefore, step S106 is executed after step S105. When executing step S106, no control is exerted on the first flap 12, that is, the control in step S104 is maintained. In step S106, the second flap 11 is controlled to rotate to a position parallel to the main board 10, and the first flap 12 is also located in a position parallel to the main board 10. The position of the air guiding device is as Figure 10 and Figure 12 shown. In this case, the upper half of the air outlet 21 is blocked, and only the air blows directly downward from the lower half of the air outlet 21, so that the air can reach the ground faster. Because in the heating mode, hot air rises from bottom to top, so blowing directly at the ground can achieve the heating effect faster.

[0093] In step S105, if the air conditioner is in the anti-direct-blowing mode, that is, when receiving an instruction to operate in the anti-direct-blowing mode, the main board 10 is controlled to move to the second position, and step S108 is executed to determine whether there is a user within a preset distance in front of the air outlet of the air conditioner. It can be detected by an infrared sensor and a ultrasonic sensor. If the judgment result is that there is a user, then step S110 is executed to control the first flap 12 to rotate to a position at a first preset angle with respect to the main board 10, and control the second flap 11 to rotate to a position at a second preset angle with respect to the main board 10. The air guiding device is as Figure 9 shown. Based on this, the two flaps are in an upward state, which can better prevent direct blowing. Further, the first flap 12 and the second flap 11 are in an erected or inclined state, and the first ventilation holes 121 on the first flap 12 and the second ventilation holes 111 on the second flap 11 can play a role in stratifying the air to better prevent direct blowing.

[0094] In step S108, if the judgment result is that there is no user, then step S109 is executed to control the first flap 12 to rotate to a position parallel to the main board 10 to achieve the maximum air supply effect.

[0095] In some other embodiments, in step S109, the second flap 11 is also controlled to rotate to a position parallel to the main board 10. Refer to Figure 8 that is Figure 8 in which the second flap 11 is flipped to a horizontal state left and right, which can reduce the air volume blown out from the lower half of the air outlet 21 and further improve the anti-direct-blowing effect.

[0096] It should be noted that the above operating mode is not restrictive. In some other embodiments, the air conditioner further includes a normal cooling mode and a normal heating mode. For example, for an air conditioner with only one air deflector in the prior art, normal control can be performed. In the normal cooling mode and the normal heating mode, both the first flap 12 and the second flap 11 are in the retracted state. At this time, the first flap 12, the second flap 11, and the main board are equivalent to one air deflector.

[0097] In the target cooling mode, if the indoor temperature is lower than the target temperature, control the compressor of the air conditioner to stop for a period of time, or control the blower 23 to stop for a period of time.

[0098] In the target heating mode, if the indoor temperature is higher than the target temperature, control the compressor of the air conditioner to stop for a period of time, or control the blower 23 to stop for a period of time.

[0099] It should be noted that the air supply mode of the present invention is not limited to the above manner. Those skilled in the art can also set the rotation of the two flaps and the position of the main board 10 according to the actual situation.

[0100] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
