Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an air conditioner and a control method for the air conditioner. Background Technology

[0002] An air conditioner, also known as an air conditioning unit, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow velocity of the air inside a building or structure. Nowadays, in addition to the basic functions of cooling and heating, the comfort of airflow is receiving increasing attention. Whether cooling or heating, if cold or hot air is blown directly onto a person, the person will feel a strong and uncomfortable airflow, and the cold air will feel harsh, thus reducing the comfort of the airflow from the air conditioner.

[0003] To improve the comfort of air conditioning, existing air conditioners are equipped with a gentle breeze structure at the air outlet. As the airflow after heat exchange is discharged from the air outlet, the drive control mechanism of the gentle breeze structure drives the gentle breeze component to rotate around the normal direction of the air guide plate. Since the gentle breeze blades of the gentle breeze component extend spirally around the normal direction of the air guide plate, when the airflow at the air outlet flows through the gentle breeze blades, the gentle breeze blades, which extend spirally around the normal direction of the air guide plate and rotate around the normal direction of the air guide plate, can disturb the airflow at the air outlet, thereby reducing the feeling of wind, softening the airflow delivered into the room, and achieving a windless air delivery effect.

[0004] However, the soft-wind structure set at the air outlet of existing air conditioners can only disturb the airflow at the air outlet to achieve a windless soft-wind air delivery mode. The working mode is single and cannot meet the user's need for a multi-functional air delivery mode. Summary of the Invention

[0005] The first objective of this invention is to provide an air conditioner that can execute any of the following working modes: conventional air supply mode, composite soft wind mode, gentle wind diffusion mode, and high air volume air supply mode. The working modes are diverse and selectable, meeting the user's needs for multi-functional air supply working modes, and can improve the air volume and comfort of the air supply, thereby enhancing the user's comfort experience.

[0006] A second objective of this invention is to provide a control method for the aforementioned air conditioner.

[0007] To achieve the first objective of this invention, an air conditioner is provided, comprising a casing and an air-expelling structure. The casing has an air inlet and an air outlet, with the air inlet located vertically above the air outlet. The air-expelling structure includes a rotation control mechanism, an air-expelling plate, and an axial flow fan. The air-expelling plate is located outside the casing, and the rotation control mechanism can control the air-expelling plate to rotate around the length of the casing. The air-expelling plate has ventilation holes extending through its normal direction. The axial flow fan's blades are located within the ventilation holes, and the fan's motor can control the rotation of the blades. The air-expelling structure can operate in any of the following modes: conventional air supply mode, composite soft wind mode, gentle wind diffusion mode, and high-volume air supply mode. Operating modes: When the air intake structure is in normal air supply mode, the air intake plate is far away from the air outlet, and the axial fan blades stop rotating; when the air intake structure is in compound soft wind mode, the air intake plate is vertically positioned below and close to the air outlet, and the axial fan blades reverse to blow the indoor airflow upwards and mix it with the heat exchange airflow blown out of the air outlet before being sent into the room; when the air intake structure is in soft wind diffusion mode, the air intake plate is positioned opposite the air outlet, and the axial fan blades rotate clockwise to diffuse the heat exchange airflow blown out of the air outlet into the room; when the air intake structure is in high air volume supply mode, the air intake plate is positioned opposite the air inlet, and the axial fan blades reverse to send the indoor airflow into the air inlet.

[0008] As can be seen from the above scheme, when the air duct structure of the air conditioner of the present invention performs the conventional air supply mode, the rotation control mechanism controls the air duct plate to rotate around the length direction of the casing so that the air duct plate drives the axial flow fan away from the air outlet, and the motor of the axial flow fan stops controlling the rotation of the axial flow fan blades, so that the axial flow fan blades stop rotating. Thus, under the action of the cross-flow impeller of the air conditioner, the indoor airflow enters the casing from the air inlet of the casing, and passes through the evaporator for heat exchange. Then, the heat exchanged airflow is sent into the room from the air outlet of the casing, and the conventional air supply mode is repeated in sequence. At this time, the air duct structure is in the reset non-working state.

[0009] When the air-drawing structure of the air conditioner of this invention operates in the compound soft wind mode, the rotation control mechanism controls the air-drawing plate to rotate around the length of the casing, so that the air-drawing plate drives the axial fan to be positioned vertically below and close to the air outlet. The motor of the axial fan controls the axial fan blades to reverse direction, blowing the indoor air upwards and mixing it with the heat-exchange airflow from the air outlet before sending it into the room. Because there is uneven heat exchange in the indoor airflow located below the casing, the air-drawing structure of the air conditioner of this invention, when operating in the compound soft wind mode, can mix the indoor airflow blowing upwards from below the casing with the heat-exchange airflow from the air outlet before sending it into the room. This improves the heat exchange effect and uniformity of the indoor airflow and reduces the hardness of the airflow, enhancing user comfort.

[0010] When the air-inducing structure of the air conditioner of this invention operates in the gentle breeze diffusion mode, the rotation control mechanism controls the air-inducing plate to rotate around the length of the casing, so that the air-inducing plate drives the axial flow fan to be positioned opposite the air outlet. The motor of the axial flow fan controls the axial flow blades to rotate clockwise to diffuse the heat exchange airflow blown from the air outlet into the room. Because the axial flow fan is positioned opposite the air outlet and the axial flow blades rotate clockwise to diffuse the heat exchange airflow blown from the air outlet into the room when the air-inducing structure of this invention operates in the gentle breeze diffusion mode, the axial flow blades can disperse and soften the heat exchange airflow blown from the air outlet. While disturbing and dispersing the airflow and changing its direction, a windless airflow effect is achieved, thereby improving user comfort.

[0011] When the air-expelling structure of the air conditioner of this invention operates in high-volume air supply mode, the rotation control mechanism controls the air-expelling plate to rotate around the length of the casing, so that the air-expelling plate drives the axial flow fan to be positioned opposite the air inlet. The motor of the axial flow fan controls the axial flow blades to reverse direction to deliver indoor airflow into the air inlet. Because the axial flow blades can assist in air intake at the air inlet when the air-expelling structure of this invention operates in high-volume air supply mode, the air intake volume and velocity are increased. After being further accelerated by the cross-flow impeller, a large volume of air is delivered to the room from the air outlet, thereby improving the heat exchange efficiency of the indoor airflow and enhancing user comfort.

[0012] Therefore, the air conditioner of the present invention can perform any of the following working modes: conventional air supply mode, composite soft wind mode, soft wind diffusion mode, and large air volume air supply mode. The working modes are diverse and selectable, which can meet the user's multi-functional air supply working mode needs, and can improve the air volume and comfort of the air supply, thereby enhancing the user's comfort.

[0013] A preferred embodiment is that the air intake plate has at least two ventilation holes, and multiple ventilation holes are arranged side by side along the length of the casing, and the number of axial flow fans is at least two, with the axial flow fan blades of one axial flow fan located in one ventilation hole.

[0014] A further improvement is that the air conditioner also includes an air guide plate, which is rotatably mounted at the air outlet along the length of the casing to open or close the air outlet.

[0015] A further proposed solution is to have rotating arms on both sides of the air intake plate along the length of the casing. The two rotating arms are rotatably supported on both sides of the casing along the length of the casing, and the rotation control mechanism can control the two rotating arms to rotate synchronously around the length of the casing.

[0016] To achieve the second object of the present invention, the present invention provides a control method for an air conditioner, using the above-mentioned air conditioner, and an infrared thermal energy monitor is provided on the casing of the air conditioner. The control method of the air conditioner includes: the infrared thermal energy monitor obtains the real-time indoor heat M; when M≤M1, the air guiding structure of the air conditioner is controlled to execute a conventional air supply mode; when M>M1, the air guiding structure is controlled to execute a large air volume air supply mode; M1 is the first preset heat.

[0017] A further solution is that a temperature sensor is provided on the casing, and the control method of the air conditioner further includes: after satisfying M>M1, the temperature sensor obtains the real-time indoor temperature T; when |T-T0|≤T1, the air guiding structure is controlled to execute a composite soft air mode; T0 is the preset target temperature of the air conditioner, and T1 is the first preset deviation temperature.

[0018] A further solution is that the control method of the air conditioner further includes: judging whether |T-T0|≤T2 is satisfied. If so, the air guiding structure is controlled to execute a soft air diffusion mode, where T2 is the second preset deviation temperature, and the second preset deviation temperature T2 is less than the first preset deviation temperature T1; or, judging whether the following two conditions are simultaneously satisfied: M1<M≤M2 and the real-time indoor temperature T satisfies the preset sleep temperature. If both are satisfied, the air guiding structure is controlled to execute a soft air diffusion mode, where M2 is the second preset heat.

[0019] A further solution is that the preset sleep temperature is T ,

[0023] , Figure 2 , Figure 1 , , ,

[0022] , and 30°C≤T p ≤34°C.

[0020] A further solution is that the first preset heat M1 = 50W; and / or, the second preset heat M2 = 100W; and / or, the first preset deviation temperature T1 = 4°C; and / or, the second preset deviation temperature T2 = 2°C.

[0021] A further solution is that the air conditioner further includes a wind deflector, and the wind deflector is rotatably arranged at the air outlet of the casing around the length direction of the casing to open or close the air outlet. The air outlet is inclined upward from the horizontal direction towards the front panel of the casing; when the air guiding structure executes the composite soft air mode, the wind deflector rotates clockwise relative to the air outlet by a first preset angle θ1, and 0<θ1≤90°; and / or, when the air guiding structure executes the soft air diffusion mode, the wind deflector rotates clockwise relative to the air outlet by a second preset angle θ2, and θ2≥90°.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0035] Air conditioner example:

[0036] See Figures 1 to 5This embodiment discloses an air conditioner 10, including a housing 11 and an air-expelling structure 13. The housing 11 has an air inlet 112 and an air outlet 113, with the air inlet 112 located vertically above the air outlet 113. The air-expelling structure 13 includes a rotation control mechanism, an air-expelling plate 131, and an axial flow fan. The air-expelling plate 131 is located outside the housing 11. The rotation control mechanism can control the air-expelling plate 131 to rotate around the length 111 of the housing 11. The air-expelling plate 131 has a ventilation hole 1311 extending through its normal direction. The axial flow fan blades 132 are located within the ventilation hole 1311, and the motor of the axial flow fan is mounted on the air-expelling plate 131 and can control the rotation of the axial flow fan blades 132. Furthermore, the air-expelling structure 13 can operate in any of the following modes: conventional air supply mode, composite soft wind mode, gentle wind diffusion mode, and high-volume air supply mode. Specifically, when the air intake structure 13 is in the normal air supply mode, the air intake plate 131 is away from the air outlet 113, and the axial fan blade 132 stops rotating; when the air intake structure 13 is in the compound soft wind mode, the air intake plate 131 is located vertically below and close to the air outlet 113, and the axial fan blade 132 is reversed to blow the indoor airflow upwards and mix it with the heat exchange airflow blown out of the air outlet 113 before sending it into the room; when the air intake structure 13 is in the soft wind diffusion mode, the air intake plate 131 is positioned opposite to the air outlet 113, and the axial fan blade 132 rotates clockwise to diffuse the heat exchange airflow blown out of the air outlet 113 into the room; when the air intake structure 13 is in the high air volume air supply mode, the air intake plate 131 is positioned opposite to the air inlet 112, and the axial fan blade 132 is reversed to send the indoor airflow into the air inlet 112.

[0037] When the air duct structure 13 of the air conditioner 10 in this embodiment performs the normal air supply mode, the rotation control mechanism controls the air duct plate 131 to rotate around the length direction 111 of the casing 11 so that the air duct plate 131 drives the axial fan away from the air outlet 113, and the motor of the axial fan stops controlling the rotation of the axial fan blade 132, so that the axial fan blade 132 stops rotating. Thus, under the action of the cross-flow impeller 15 of the air conditioner 10, the indoor airflow enters the casing 11 from the air inlet 112 of the casing 11, and passes through the evaporator 14 for heat exchange. Then the heat exchanged airflow is sent into the room from the air outlet 113 of the casing 11, and the normal air supply mode is run in a reciprocating sequence. At this time, the air duct structure 13 is in the reset non-working state.

[0038] When the air-expelling structure 13 of the air conditioner 10 in this embodiment executes the composite soft wind mode, the rotation control mechanism controls the air-expelling plate 131 to rotate around the length direction 111 of the casing 11, so that the air-expelling plate 131 drives the axial flow fan to be positioned vertically below and close to the air outlet 113. The motor of the axial flow fan controls the axial flow fan blades 132 to reverse direction, so that the indoor airflow is blown upwards and mixed with the heat exchange airflow blown out of the air outlet 113 before being sent into the room. See [link to relevant documentation]. Figure 6 and Figure 7 As shown. Due to uneven heat exchange in the indoor airflow located below the casing 11, the air intake structure 13 of the air conditioner 10 in this embodiment can mix the indoor airflow below the casing 11 with the heat exchange airflow blown out from the air outlet 113 when executing the composite soft wind mode, and then send them into the room together. On the one hand, this can improve the heat exchange effect and heat exchange uniformity of the indoor airflow, and on the other hand, it can reduce the hardness of the airflow and improve the user's comfort.

[0039] When the air-expelling structure 13 of the air conditioner 10 in this embodiment executes the gentle breeze diffusion mode, the rotation control mechanism controls the air-expelling plate 131 to rotate around the length direction 111 of the casing 11 so that the air-expelling plate 131 drives the axial flow fan to be positioned opposite the air outlet 113, and the motor of the axial flow fan controls the axial flow fan blades 132 to rotate clockwise so as to diffuse the heat exchange airflow blown out of the air outlet 113 into the room. See Figure 8 and Figure 9 As shown. In this embodiment, when the air intake structure 13 executes the soft wind diffusion mode, the axial fan and the air outlet 113 are arranged opposite each other, and the axial fan blade 132 rotates clockwise to diffuse the heat exchange airflow blown out of the air outlet 113 into the room. The axial fan blade 132 can disperse and soften the heat exchange airflow blown out of the air outlet 113. While disturbing and dispersing to change the airflow direction, it achieves a windless air supply effect, thereby improving the user's comfort.

[0040] When the air-expelling structure 13 of the air conditioner 10 in this embodiment operates in high-volume air supply mode, the rotation control mechanism controls the air-expelling plate 131 to rotate around the length direction 111 of the casing 11 so that the air-expelling plate 131 drives the axial flow fan to be positioned opposite the air inlet 112, and the motor of the axial flow fan controls the axial flow fan blades 132 to reverse so as to send indoor airflow into the air inlet 112. See [link to relevant documentation]. Figure 10 and Figure 11 As shown. In this embodiment, when the air intake structure 13 performs the large air volume supply mode, the axial flow fan blade 132 can assist in air intake at the air inlet 112, which increases the air volume and the air velocity. After being accelerated again by the cross-flow impeller 15, it can achieve a large air volume supply to the room through the air outlet 113, thereby improving the heat exchange efficiency of the indoor airflow and thus enhancing the user's comfort.

[0041] Therefore, the air conditioner 10 in this embodiment can execute any of the following working modes: conventional air supply mode, composite soft wind mode, soft wind diffusion mode, and large air volume air supply mode. The working modes are diverse and selectable, which can meet the user's multi-functional air supply working mode needs, and can improve the air volume and comfort of the air supply, thereby enhancing the user's comfort.

[0042] In order to further improve the working stability and reliability of the air-exhaust structure 13, the air-exhaust plate 131 of this embodiment has at least two ventilation holes 1311. Multiple ventilation holes 1311 are arranged side by side in the length direction 111 of the casing 11, and the number of axial flow fans is at least two, with the axial flow fan blade 132 of one axial flow fan located in one ventilation hole 1311.

[0043] To improve the stability and reliability of the rotation of the air intake plate 131, in this embodiment, the air intake plate 131 is provided with rotating arms 1312 on both sides along the length direction 111 of the housing 11. The two rotating arms 1312 are rotatably supported on both sides of the housing 11 along the length direction 111 of the housing 11. The rotation control mechanism can control the two rotating arms 1312 to rotate synchronously around the length direction 111 of the housing 11. Specifically, in this embodiment, the rotation control mechanism is a drive motor, which can control the two rotating arms 1312 to rotate synchronously around the length direction 111 of the housing 11.

[0044] To further improve air delivery efficiency and comfort, the air conditioner 10 in this embodiment also includes an air guide plate 12, which is rotatably disposed at the air outlet 113 around the length direction 111 of the casing 11 to open or close the air outlet 113. Specifically, in this embodiment, the air outlet 113 is inclined from bottom to top towards the front panel 114 of the casing 11 relative to the horizontal direction, so as to better deliver air to the indoor space.

[0045] In order to improve the intelligent control of the air conditioner 10, the casing 11 of the air conditioner 10 in this embodiment is equipped with an infrared thermal energy monitor and a temperature sensor. The infrared thermal energy monitor is used to detect the real-time heat in the room, and the temperature sensor is used to detect the real-time temperature in the room.

[0046] Example of an air conditioner control method:

[0047] The control method of the air conditioner in this embodiment uses the air conditioner 10 of the above embodiment. The control method of the air conditioner 10 in this embodiment includes receiving signals sent by a remote control and performing the following specific steps.

[0048] First, execute step S1 to execute the power-on command and set the preset target temperature T0 of the air conditioner 10.

[0049] Then, step S2 is executed, where the infrared thermal energy monitor acquires the real-time indoor heat M, and the temperature sensor acquires the real-time indoor temperature T.

[0050] Next, step S3 is executed to determine whether M≤M1 is satisfied, where M1 is the first preset heat. When it is determined that M≤M1 is satisfied, it means that the heat detected by the infrared thermal energy detector at this time only comes from the reflection of the indoor wall and indoor objects. At this time, there is no obvious heat source in the room. Then, step S4 is executed to control the air-drawing structure 13 of the air conditioner 10 to execute the normal air supply mode. That is, the rotation control mechanism controls the air-drawing plate 131 to rotate around the length direction 111 of the casing 11 so that the air-drawing plate 131 drives the axial flow fan away from the air outlet 113, and the motor of the axial flow fan stops controlling the rotation of the axial flow fan blade 132, so that the axial flow fan blade 132 stops rotating. Thus, under the action of the cross-flow impeller 15 of the air conditioner 10, the indoor airflow enters the casing 11 from the air inlet 112 of the casing 11, and passes through the evaporator 14 for heat exchange. Then, the heat exchanged airflow is sent into the room from the air outlet 113 of the casing 11. The normal air supply mode is run in a reciprocating sequence. At this time, the air-drawing structure 13 is in the reset non-working state.

[0051] When the condition is determined that M≤M1, i.e., M>M1, it means that the heat detected by the infrared thermal energy detector comes not only from the reflection of indoor walls and indoor objects, but also from other indoor heat sources, including electronic heat dissipation equipment such as computers, and heat dissipation from people sitting, working, or lightly exercising. In this case, step S5 is executed, controlling the air-draft structure 13 of the air conditioner 10 to execute a high-volume air supply mode. Specifically, the rotation control mechanism controls the air-draft plate 131 to rotate around the length direction 111 of the casing 11, so that the air-draft plate 131 drives the axial flow fan to be positioned opposite the air inlet 112. Furthermore, the motor of the axial flow fan controls the axial flow blades 132 to reverse direction to send indoor airflow into the air inlet 112. (See [link to relevant documentation]). Figure 10 and Figure 11 As shown. In this embodiment, when the air intake structure 13 performs the high-volume air supply mode, the axial fan blades 132 can assist in air intake at the air inlet 112, which increases the air intake volume and the air intake speed. After being accelerated again by the cross-flow impeller 15, it can achieve high-volume air supply to the room through the air outlet 113, thereby improving the heat exchange efficiency of the indoor airflow and enhancing the user's comfort.

[0052] Then, step S6 is executed to determine whether |T-T0|≤T1 is satisfied, where T1 is the first preset deviation temperature. When it is determined that |T-T0|≤T1 is satisfied, it indicates that the initial temperature control of the indoor airflow has been achieved. Then, step S7 is executed to control the air intake structure 13 of the air conditioner 10 to execute the composite soft wind mode. That is, the rotation control mechanism controls the air intake plate 131 to rotate around the length direction 111 of the casing 11 so that the air intake plate 131 drives the axial flow fan to be positioned vertically below and close to the air outlet 113. The motor of the axial flow fan controls the axial flow fan blades 132 to reverse so that the indoor airflow is blown upward and mixed with the heat exchange airflow blown out of the air outlet 113 before being sent into the room. See Figure 6 and Figure 7 As shown. Due to uneven heat exchange in the indoor airflow located below the casing 11, the air intake structure 13 of the air conditioner 10 in this embodiment can mix the indoor airflow below the casing 11 with the heat exchange airflow blown out from the air outlet 113 when executing the composite soft wind mode, and then send them into the room together. On the one hand, this can improve the heat exchange effect and heat exchange uniformity of the indoor airflow, and on the other hand, it can reduce the hardness of the airflow and improve the user's comfort.

[0053] In order to further improve air supply efficiency and comfort, the control method of the air conditioner 10 in this embodiment controls the air guide plate 12 to rotate clockwise relative to the air outlet 113 by a first preset angle θ1 when controlling the air intake structure 13 to execute the composite soft wind mode, and 0<θ1≤90°.

[0054] If the condition is not met (|T-T0|≤T1), it means that the initial temperature of the indoor airflow has not yet reached the expected value, and step S5 should be executed.

[0055] After executing step S7, when the air duct structure 13 of the air conditioner 10 executes the composite soft wind mode, steps S8 and S9 can be executed simultaneously. As long as one of the judgment conditions in steps S8 and S9 is met, step S10 can be executed.

[0056] Execute step S8 to determine whether |T-T0|≤T2 is satisfied, where T2 is the second preset deviation temperature, and the second preset deviation temperature T2 is less than the first preset deviation temperature T1. If |T-T0|≤T2 is satisfied, it indicates that the preset target temperature control of the indoor airflow has been basically achieved. Then, execute step S10 to control the air-drawing structure 13 of the air conditioner 10 to execute the soft wind diffusion mode. That is, the rotation control mechanism controls the air-drawing plate 131 to rotate around the length direction 111 of the casing 11 so that the air-drawing plate 131 drives the axial flow fan to be positioned opposite the air outlet 113, and the motor of the axial flow fan controls the axial flow fan blade 132 to rotate clockwise to diffuse the heat exchange airflow blown out of the air outlet 113 into the room. See [link to relevant documentation]. Figure 8 and Figure 9 As shown. In this embodiment, when the air intake structure 13 executes the soft wind diffusion mode, the axial fan and the air outlet 113 are positioned opposite each other, and the axial fan blades 132 rotate clockwise to diffuse the heat exchange airflow blown out of the air outlet 113 into the room. The axial fan blades 132 can disperse and soften the heat exchange airflow blown out of the air outlet 113. While disturbing and dispersing the airflow and changing the direction of airflow, a windless air delivery effect is achieved, thereby improving the user's comfort. When it is determined that |T-T0|≤T2 is not satisfied, it means that the temperature control of the indoor airflow has not yet reached the preset target, so step S7 is continued.

[0057] In order to further improve the air supply efficiency and comfort, when the control method of the air conditioner 10 in this embodiment controls the air guiding structure 13 to execute the gentle air diffusion mode, it synchronously controls the air deflector 12 to rotate clockwise by a second preset angle θ2 relative to the air outlet 113, and θ2≥90°.

[0058] Execute step S9 to determine whether the following two conditions are satisfied simultaneously: M1 < M ≤ M2 and the indoor real-time temperature T satisfies the preset sleep temperature, where M2 is the second preset heat quantity.
