The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
First, an air conditioner provided according to an embodiment of the present invention will be described, and the air conditioner may include: an electrical box 100 (such as the electrical box 100 shown in fig. 1), an outdoor unit of an air conditioner, and an indoor unit of an air conditioner, where the outdoor unit of the air conditioner is disposed outdoors and includes a casing and a fan located in the casing; an air outlet is formed in the shell, and the fan is arranged close to the air outlet; the electrical box 100 of the outdoor unit of the air conditioner is disposed in the casing and located on a side of the fan away from the air outlet.
The air outlet on the shell of the air conditioner outdoor unit is communicated with the inside and the outside of the air conditioner outdoor unit, so that the air exchange between the air conditioner outdoor unit and an outdoor unit is realized. Referring to fig. 2, the electrical box 100 of the air conditioner indoor unit is generally detachably fixed in the casing of the air conditioner outdoor unit, and specifically, the detachable connection between the electrical box 100 and the casing of the air conditioner outdoor unit can be realized through a threaded connection and a clamping connection.
Referring to fig. 3, fig. 3 isbase:Sub>A cross-sectional view taken along linebase:Sub>A-base:Sub>A of fig. 2, in which the electrical components 112 of the outdoor unit are placed in the electrical box 100, and the electrical box 100 is used for protecting the electrical components 112 of the outdoor unit. The electrical component 112 needs to be powered on to operate normally within a certain temperature range. The environment temperature of the electrical component 112 is too high or too low, which may affect the normal operation of the electrical component 112 and the normal operation of the outdoor unit of the air conditioner.
For example, the normal operating environment temperature of electrical component 112 is 5-55 ℃, and then electrical component 112 cannot operate normally when the operating environment temperature of electrical component 112 is less than 5 ℃ or greater than 55 ℃. However, in the process of operating the electrical component 112, the electrical component 112 generates heat continuously, and the ambient temperature of the electrical component 112 is increased continuously, so that heat dissipation needs to be performed inside the electrical box 100 to ensure the normal operation of the electrical component 112 inside the electrical box 100.
Referring to fig. 1, an electric box 100 of an outdoor unit of an air conditioner according to an embodiment of a first aspect of the present invention may include: a box body 110 and a cover 130, wherein the box body 110 has an accommodating cavity 111 (for example, the accommodating cavity 111 shown in fig. 3), and the box body 110 is provided with an opening communicated with the accommodating cavity 111; the accommodating cavity 111 is used for accommodating electrical components 112 of the outdoor unit of the air conditioner. The cover 130 covers the opening, and an air outlet 131 (such as the air outlet 131 shown in fig. 8) is formed on the cover 130 and is communicated with the opening.
Therefore, the electrical box 100 is composed of the box body 110 and the cover body 130, maintenance and replacement of the electrical component 112 inside the electrical box 100 by maintenance personnel are facilitated, the maintenance personnel only need to open the cover body 130 of the electrical box 100, the electrical component 112 needing to be replaced is taken out through the opening of the box body 110, and then the electrical component 112 capable of normally operating is assembled into the accommodating cavity 111 through the opening.
The box body 110 is further provided with an air inlet, the air inlet may be disposed on a side wall of the box body 110 or on a bottom wall of the box body 110, and the air inlet is located on one side of the air outlet 131 away from the fan. When the fan rotates, the fan drives the airflow at one side of the air inlet to flow, the air pressure at one side of the air outlet 131 is reduced, so that an air pressure difference is formed between the air inlet and the air outlet 131, the airflow flows from one side with higher air pressure (for example, one side of the air inlet of the electrical box 100) to one side with lower air pressure (for example, one side of the air outlet 131 of the electrical box 100), the airflow enters the electrical box 100 from the air inlet of the electrical box 100, takes away the heat inside the electrical box 100, and is discharged through the air outlet 131 of the electrical box 100, thereby achieving the purpose of dissipating heat of the electrical elements 112 inside the electrical box 100.
Referring to fig. 2, the box body 110 may further include a damper assembly 120, and the damper assembly 120 is disposed at the air outlet 131. Referring to fig. 5, the damper assembly 120 may include: a damper 121 and a connecting portion 123. The damper 121 is formed in a plate shape and is disposed outside the accommodating chamber 111. The connecting portion 123 is rotatably connected to the air outlet 131. The connection portion 123 includes a connection plate 1231 connected to the damper 121, and a portion of the connection plate 1231 is disposed outside the accommodating chamber 111 and a portion is located inside the accommodating chamber 111. The coupling plate 1231 and the damper 121 are used to cover the outlet port 131.
It should be noted that, when the electrical component 112 in the electrical box 100 needs to dissipate heat, the damper assembly 120 rotates, and the connection board 1231 and the damper 121 open the air outlet 131, so that the air flow can flow through the accommodating cavity 111 in the electrical box 100 from the air inlet, and flow out from the air outlet 131 to take away heat in the accommodating cavity 111. Referring to fig. 4, when the electrical component 112 in the electrical box 100 does not need to dissipate heat, the air door assembly 120 rotates, and the connecting plate 1231 and the air door 121 cover the air outlet 131, so that the airflow in the accommodating cavity 111 cannot flow, and the electrical component 112 is insulated, thereby ensuring the normal operation of the electrical component 112.
Further, the opening and closing degrees of the damper assemblies 120 are different, and the heat dissipation effect of the accommodating cavity 111 is also different. The opening and closing angle of the air door assembly 120 is large, the actual air outlet area of the air outlet 131 is large, and the heat dissipation effect of the accommodating cavity 111 in the electrical box 100 is good. The opening and closing angle of the air door assembly 120 is small, the actual air outlet area of the air outlet 131 is small, and the heat dissipation effect of the accommodating cavity 111 in the electrical box 100 is poor, wherein the opening and closing angle of the air door assembly 120 refers to an included angle (for example, an included angle α shown in fig. 10) between the surface of one side of the air door 121 facing the cover 130 and the outer surface of one side of the air outlet 131 of the cover 130.
Referring to fig. 6, the plate surface of the connecting plate 1231 and the plate surface of the damper 121 are angled, so that the portion of the connecting plate 1231 connected to the damper 121 forms a first protruding structure 124, and the first protruding structure 124 protrudes in a direction away from the accommodating cavity 111 (e.g., in the positive Y direction shown in fig. 4) when the damper 121 is located at the position covering the air outlet 131 (e.g., the position of the damper assembly 120 shown in fig. 4).
It should be noted that the surface of the connecting plate 1231 is the plane where the connecting plate 1231 is located, regardless of the thickness of the connecting plate 1231; the plate surface of the damper 121 means a plane where the damper 121 is located, regardless of the thickness of the damper 121; the included angle between the plate surface of the connecting plate 1231 and the plate surface of the air door 121 means the included angle between the plane where the connecting plate 1231 is located and the plane where the air door 121 is located, regardless of the thicknesses of the connecting plate 1231 and the air door 121.
Further, referring to fig. 4, fig. 4 is an enlarged view of a position D shown in fig. 3, when the damper assembly 120 is located at a position for covering the air outlet 131, water drops outside the air-conditioning outdoor unit fall to the air outlet 131 of the electrical box 100, the connecting plate 1231 (for example, the connecting plate 1231 shown in fig. 6) and the damper 121 are covered on the air outlet 131, the water drops fall to the connecting plate 1231 and slide down along the inclined direction of the connecting plate 1231 under the action of gravity, and the water drops flow through the first protruding structure 124 and then leave the electrical box 100 or slide down along the damper 121, so that the water dropping to the air outlet 131 of the electrical box 100 cannot enter the interior of the electrical box 100, the electrical component 112 inside the electrical box 100 is prevented from being short-circuited, and the normal operation of the electrical component 112 inside the electrical box 100 is ensured.
In some embodiments, referring to fig. 5, the connecting portion 123 may further include a rotating shaft connector 1232, which is located in the accommodating cavity 111, is disposed at an end of the connecting portion 123 far from the damper 121, and is connected to the connecting plate 1231. Referring to fig. 12, the damper assembly 120 may further include a rotating shaft 122, and the rotating shaft 122 penetrates through the rotating shaft connector 1232 and is rotatably connected to the cover 130 or the box body 110. Therefore, the rotation of the rotating shaft 122 is converted into the rotation of the air door assembly 120 through the rotating shaft connecting piece 1232, and the air door assembly 120 covers and opens the air outlet 131.
For example, referring to fig. 5, one end of the rotating shaft 122 is connected to an output shaft of a driving motor (for example, the driving motor described below), the output shaft of the driving motor rotates to drive the rotating shaft 122 to rotate, the rotating shaft 122 drives the connecting portion 123 to rotate, and the connecting portion 123 drives the damper 121 to rotate, so that the damper assembly 120 can rotate between a position where the air outlet 131 is covered (for example, the position of the damper assembly 120 shown in fig. 1) and a position where the air outlet 131 is opened (for example, the position of the damper assembly 120 shown in fig. 5), thereby achieving the problem of adjusting the opening and closing angle of the damper assembly 120 according to specific situations.
In some embodiments, referring to fig. 6, the plane of the connecting plate 1231 is angled with respect to the axis of the rotating shaft 122, such that the portion of the connecting plate 1231 connected to the rotating shaft connector 1232 forms a second protruding structure 125, and the second protruding structure 125 protrudes toward a direction close to the accommodating cavity 111 (e.g., a negative Y direction shown in fig. 4) when the damper assembly 120 is located at the cover outlet 131.
Further, referring to fig. 7 and 8, when the air door assembly 120 opens the air outlet 131, and the opening degree of the air door assembly 120 reaches the maximum, the side surface of the connecting plate 1231 close to the cover 130 abuts against the cover 130, and the second protrusion structure 125 abuts against the upper edge of the air outlet 131, so that, on one hand, the second protrusion structure 125 limits the opening and closing degree of the air door assembly 120, and on the other hand, when the opening and closing degree of the air door assembly 120 reaches the maximum, the air outlet area of the air outlet 131 is the maximum.
Further, referring to fig. 9, fig. 9 is a cross-sectional view taken along line B-B shown in fig. 8, the opening and closing angle of the damper assembly 120 is greater than 90 °, referring to fig. 10, and fig. 10 is an enlarged view taken along line E shown in fig. 9, under the action of the blower of the outdoor unit of the air conditioner, the flow velocity of the air flow at the position of the air outlet 131 is significantly increased, thereby increasing the pressure difference between the air inlet and the air outlet 131, increasing the flow velocity of the air flow in the accommodating chamber 111, and improving the heat dissipation effect in the accommodating chamber 111.
In some embodiments, referring to fig. 4, the connecting portion 123 may further include an abutting plate 1233, where the abutting plate 1233 is located in the accommodating cavity 111, and is disposed at an end of the rotating shaft connector 1232 away from the connecting plate 1231, and is connected to the rotating shaft connector 1232; the abutting plate 1233 is adapted to abut against the inner surface of the cover 130 when the damper assembly 120 is positioned to cover the outlet 131.
Further, when the damper assembly 120 rotates from the position of opening the outlet 131 to the position of covering the outlet 131, the abutting plate 1233 moves toward the inner surface of the cover 130, and the damper 121 moves toward the outer surface of the outlet 131. Referring to fig. 4, when the damper 121 covers the outlet 131, the contact plate 1233 contacts the inner surface of the cover 130. Thus, the abutting of the abutting plate 1233 and the inner surface of the cover 130 limits the movement of the air door 121 towards the outer surface of the cover 130, and avoids the hard collision between the air door 121 and the outer surface of the cover 130, thereby improving the stability of the air door assembly 120 in the process of covering the air outlet 131, prolonging the service life of the air door assembly 120, and improving the quality of products.
In some embodiments, referring to fig. 6, the plate surface of the abutting plate 1233 is angled with respect to the axis of the rotating shaft 122, such that the portion of the abutting plate 1233 connected to the rotating shaft connector 1232 forms a third protruding structure 126, and the third protruding structure 126 protrudes toward a direction close to the accommodating chamber 111 (e.g., the negative Y direction shown in fig. 4) at the position where the damper assembly 120 covers the outlet 131.
In this way, when the damper assembly 120 is in a position for covering the outlet 131 (for example, the position of the damper assembly 120 shown in fig. 4), the end of the contact plate 1233 away from the rotating shaft connector 1232 abuts against the inner surface of the cover 130, and thus, the rotation angle of the contact plate 1233 is reduced, and thus the rotation angle of the damper assembly 120 is reduced, while ensuring that the contact plate 1233 abuts against the inner lid of the cover 130.
In some embodiments, referring to fig. 2, the damper assembly 120 is in a position covering the outlet 131, and a portion of the damper 121 covers the outlet 131 and another portion covers an edge of the outlet 131. Thus, when the air door assembly 120 covers the air outlet 131, the air door assembly 120 can completely cover the air outlet 131, so that insect prevention and dust prevention inside the electrical box 100 can be better realized.
Specifically, referring to fig. 2, when the air door assembly 120 is at a position for covering the air outlet 131, one end of the air door 121 in the X direction covers an edge of the air outlet 131, and a distance (for example, a value a shown in fig. 2) that one end of the air door 121 in the X direction exceeds the air outlet 131 is greater than or equal to 4mm, so that when the air door assembly 120 is used for covering the air outlet 131, the air outlet 131 can be completely covered, and insect prevention and dust prevention inside the electrical box 100 are ensured.
For example, referring to fig. 2, in a specific implementation, the distance (for example, the value of a shown in fig. 2) that one end of the damper 121 exceeds the air outlet 131 in the X direction is set to be 5mm, so that on one hand, when the damper assembly 120 covers the air outlet 131, the air outlet 131 can be completely covered, and wind and dust prevention inside the electrical box 100 can be ensured; on the other hand, the raw material cost for the production of the damper 121 is reasonably controlled.
In some embodiments, referring to fig. 13, the electrical box 100 may further include a diversion flange 140, the diversion flange 140 is disposed on a side of the box body 110 close to the air outlet 131 (for example, a side of the box body 110 in the positive Y direction shown in fig. 14), the diversion flange 140 is disposed obliquely, and a diversion direction of the diversion flange 140 faces the air outlet 131. Thus, water splashed on the diversion flange 140 can flow to the air outlet 131 along the inclined direction of the diversion flange 140 and be discharged from the air outlet 131.
It should be noted that, when the air outlet 131 of the electrical box 100 is opened, referring to fig. 14, water in the environment may enter the electrical box 100 through the air outlet 131, and water drops onto the diversion flange 140, and under the action of gravity, the water dropping onto the diversion flange 140 flows to the air outlet 131 along the inclined direction of the diversion flange 140, and is discharged out of the electrical box 100 through the air outlet 131. Further, water in the environment is prevented from entering the electrical box 100, and the normal operation of the electrical components 112 in the electrical box 100 is ensured.
In some embodiments, referring to fig. 14, fig. 14 is an exploded view of the electrical box 100, and the electrical box 100 of the outdoor unit of the air conditioner may further include a mesh enclosure structure 150, where the mesh enclosure structure 150 is located inside the electrical box 100 and covers the opening of the box body 110. The outdoor unit of the air conditioner is located outdoors, and in the long-time operation process, the inside of the outdoor unit of the air conditioner has the condition that the winged insects enter the inside of the electrical box 100 from the air outlet 131, so that the mesh enclosure structure 150 covering the opening of the box body 110 is arranged, the winged insects are prevented from entering the containing strength, and the normal operation of the electrical component 112 inside the electrical box 100 is further ensured.
Further, referring to fig. 13, a portion of the mesh enclosure structure 150 is overlapped on the diversion flange 140, and the mesh enclosure structure 150 is disposed in an inclined manner and has the same inclined direction as the diversion flange 140. Thus, when water drops are splashed into the electric appliance box 100, the water drops flow along the inclined direction of the mesh enclosure structure 150, flow to the diversion flange 140, flow along the inclined direction of the diversion flange 140, and flow out of the electric appliance box 100 through the air outlet 131.
In some embodiments, referring to fig. 13, the mesh cap structure 150 may include: a substrate 151 and a plurality of bumps 152. A part of the base plate 151 is lapped on the diversion flange 140, and the base plate 151 is obliquely arranged and has the same inclination direction with the diversion flange 140; the bumps 152 are arranged in an array, and each bump 152 is provided with a through hole 153 penetrating through the bump 152 and the substrate 151. Thus, on the premise of ensuring ventilation of the mesh enclosure structure 150, the winged insects are prevented from entering the electric appliance box 100.
Wherein, set up through-hole 153 of running through lug 152 and base plate 151 through setting up on a plurality of lugs 152 for the perisporium of through-hole 153 protrudes base plate 151, like this, when water passes through air outlet 131 and splashes to screen panel structure 150, the perisporium of through-hole 153 can be supported water and enter into in the through-hole 153, and the inside drying of electrical apparatus box 100 is further guaranteed, guarantees the normal operating of electrical apparatus component 112 in electrical apparatus box 100.
Specifically, the aperture of the through hole 153 (e.g. the value of b shown in fig. 13) may be set to 5mm, so that, under the condition that the ventilation of the through hole 153 is ensured, it can be ensured that most flying insects cannot enter the accommodating cavity 111, and further, the normal operation of the electrical component 112 in the electrical box 100 is ensured.
The air conditioner provided by the embodiment of the invention can further comprise: a first temperature sensor, a second temperature sensor, a drive mechanism 160, and a controller. The first temperature sensor is disposed in the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner, and the first temperature sensor is configured to detect a temperature of the accommodating cavity 111. The second temperature sensor is arranged on the outer side of the air conditioner outdoor unit and used for detecting the ambient temperature.
Referring to fig. 11, the driving mechanism 160 is connected to the connection part 123 of the electrical box 100 of the outdoor unit of the air conditioner; the driving mechanism 160 may be configured as a driving motor, an output shaft of the driving motor is connected to the rotating shaft 122 of the connecting portion 123, and the rotation of the air door assembly 120 is driven by the rotation of the driving motor, so as to drive the air door assembly 120 to rotate between a position for covering the air outlet 131 and a position for opening the air outlet 131.
Specifically, referring to fig. 11, the connecting portion 123 may further include a rotating shaft fixing block 170, the rotating shaft fixing block 170 is clamped to the cover 130, the rotating shaft 122 is rotatably connected to the rotating shaft fixing block 170, the driving motor is fixed to the rotating shaft fixing block 170, the rotating shaft 122 is fixedly connected to an output shaft of the driving motor, and the rotation of the driving motor drives the rotating shaft 122 to rotate, so as to drive the air door 121 to rotate.
The controller is electrically connected to the first temperature sensing module, the second temperature sensing module and the driving mechanism 160, and the controller is configured to control a rotation direction of the driving mechanism 160 according to detection results of the first temperature sensor and the second temperature sensor.
Referring to fig. 15, a method for controlling an air conditioner according to an embodiment of the present invention includes: s101, acquiring a starting-up instruction; s102, acquiring a detection result of the second temperature sensor according to the starting instruction; s103, if the ambient temperature Tm is greater than the first predetermined temperature T1, the driving mechanism 160 is controlled to drive the damper assembly 120 to rotate to a first opening/closing angle (for example, the position where the damper assembly 120 rotates as shown in fig. 8), so that a vertical projection of the damper assembly 120 in the plane where the air outlet 131 is located does not overlap with the air outlet 131.
It should be noted that, referring to fig. 5, the first preset temperature T1 is higher, and in an environment where an external environment temperature is higher, and in an operation process of the electrical component 112 inside the electrical box 100, temperature rise inside the electrical box 100 is faster, so that when the second temperature sensor detects that the environment temperature Tm is greater than the first preset temperature T1, the controller controls the driving mechanism 160 to drive the air door assembly 120 to rotate to take the first opening and closing angle, so as to maximize an actual air outlet area of the air outlet 131, and optimize a heat dissipation effect inside the accommodating cavity 111.
S104, if the ambient temperature Tm is lower than the second predetermined temperature T2, the driving mechanism 160 is controlled to drive the air door assembly 120 to cover the air outlet 131.
It should be noted that the value of the second preset temperature T2 is lower, and in an environment with an extremely low external environment temperature, the temperature of the accommodating cavity 111 in the electrical box 100 cannot reach the most suitable temperature range for the normal operation of the electrical component 112, and during the operation of the electrical component 112 in the electrical box 100, the temperature rise inside the electrical box 100 is slower, so that when the second temperature sensor detects that the environment temperature Tm is lower than the second preset temperature, the S104 controller controls the driving mechanism 160 to drive the air door assembly 120 to cover the air outlet 131, so as to reduce the air flow inside the accommodating cavity 111, and thus the temperature inside the accommodating cavity 111 can be quickly raised to the most suitable temperature range for the operation of the electrical component 112.
S105, if T2 is less than or equal to Tm less than or equal to T1, the driving mechanism 160 is controlled to drive the damper assembly 120 to rotate to a second opening and closing angle (for example, the position of the damper assembly 120 rotating shown in FIG. 9), so that the vertical projection of the damper assembly 120 in the plane of the air outlet 131 is partially overlapped with the air outlet 131.
Therefore, according to different environmental temperatures, the control damper assembly 120 is rotated to different opening and closing angles to achieve different heat dissipation effects, so that the electrical component 112 inside the electrical box 100 is in a suitable temperature range, and the electrical component 112 can normally operate at different environmental temperatures.
For example, referring to fig. 15, the first preset temperature T1 is set to 40 °, the second preset temperature T2 is 5 °, the opening and closing angle range of the damper assembly 120 is 0 to 120 °, the first opening and closing angle is the maximum opening and closing angle of the damper assembly 120, the first opening and closing angle is 120 °, and the second opening and closing angle is 40 °. When the second temperature sensor detects that the ambient temperature is higher than 40 ℃, the ambient temperature is too high, and the temperature rising speed is high when the electrical component 112 in the electrical box 100 operates, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the position with the opening and closing degree of 120 degrees, so that the maximum air outlet amount is ensured, and the best heat dissipation effect is achieved.
Referring to fig. 15, when the second temperature sensor detects that the ambient temperature is less than 5 ℃, the ambient temperature is too low and is lower than the normal operating temperature of the electrical component 112 in the electrical box 100, the driving mechanism 160 is controlled to drive the air door assembly 120 to cover the air outlet 131, so as to keep the temperature of the electrical component 112 in the electrical box 100.
Referring to fig. 15, when the second temperature sensor detects that the ambient temperature is 5 ℃ to 40 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the second opening and closing angle of 40 °, so that the treatment projection of the air door assembly 120 in the plane where the air outlet 131 is located is partially overlapped with the air outlet 131, and at this time, the air outlet area of the air outlet 131 is small.
In some embodiments, referring to fig. 15, S104, after controlling the driving mechanism 160 to drive the damper assembly 120 to cover the air outlet 131 if the ambient temperature Tm is less than the second preset temperature T2, the method may further include: s105, obtaining a detection result of the first temperature sensor, and if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner is greater than the third preset temperature T3, controlling the driving mechanism 160 to drive the air door assembly 120 to rotate to the second opening and closing angle.
For example, referring to fig. 15, the third preset temperature T3 is 15 ℃, the initial ambient temperature Tm is less than 5 ℃ than the second preset temperature, the air outlet 131 is covered by the damper assembly 120, the electrical components 112 in the electrical box 100 operate to generate heat, and the ambient temperature inside the electrical box 100 rises. When the first temperature sensor detects that the temperature inside the electrical box 100 is higher than 15 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the position where the opening and closing angle is 40 degrees, so as to dissipate heat inside the electrical box 100.
In some embodiments, referring to fig. 15, S105, after the driving mechanism 160 drives the damper assembly 120 to rotate to the second opening and closing angle, the method further comprises: s106, obtaining a detection result of the first temperature sensor, and if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner is greater than the fourth preset temperature T4, controlling the driving mechanism 160 to drive the air door assembly 120 to rotate to a third opening angle (for example, a position where the air door assembly 120 shown in fig. 10 rotates), so that a vertical projection of the air door assembly 120 in a plane where the air outlet 131 is located partially overlaps with the air outlet 131.
And the third opening and closing angle is larger than the second opening and closing angle. That is to say, the actual air outlet area of the air outlet 131 is larger when the third opening angle of the air door component 120 is compared with the second opening angle of the air door component 120, and the heat dissipation effect of the electrical component 112 inside the accommodating cavity 111 is better.
It should be noted that, if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner, which is detected by the first temperature sensor, is not greater than the fourth preset temperature T4, the damper assembly 120 is not moved and is kept at the second opening and closing angle position.
For example, referring to fig. 15, the fourth preset temperature T4 is 25 ℃, the third opening angle is 80 °, and when the temperature inside the electrical box 100 further increases and the first temperature sensor detects that the temperature inside the electrical box 100 is greater than 25 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the position where the opening angle is 80 °, so as to increase the air outlet area of the air outlet 131, enhance the heat dissipation effect, and perform better heat dissipation on the inside of the electrical box 100.
In some embodiments, referring to fig. 15, S106, after the driving mechanism 160 drives the damper assembly 120 to rotate to the third opening angle, the method further comprises: s107, obtaining a detection result of the first temperature sensor, and if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner is greater than the fifth preset temperature T5, controlling the driving mechanism 160 to drive the air door assembly 120 to rotate to a fourth opening angle, so that a vertical projection of the air door assembly 120 in a plane where the air outlet 131 is located partially overlaps the air outlet 131.
And the fourth opening angle is larger than the third opening angle. That is to say, when the fourth opening angle of the damper assembly 120 is compared with the third opening angle of the damper assembly 120, the actual air outlet area of the air outlet 131 is larger, and the heat dissipation effect on the electrical component 112 inside the accommodating cavity 111 is better.
It should be noted that, if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner, which is detected by the first temperature sensor, is still not greater than the fifth preset temperature T5, the damper assembly 120 is not moved and remains at the position of the third opening angle.
For example, referring to fig. 15, the fifth preset temperature T5 is 35 ℃, the fourth opening angle is 120 °, when the temperature inside the electrical box 100 further increases, the first temperature sensor detects that the temperature inside the electrical box 100 is greater than 35 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to a position where the opening degree is 120 °, that is, the maximum opening and closing angle of the air door assembly 120, so that the air outlet area of the air outlet 131 reaches the maximum, the heat dissipation effect is enhanced, and better heat dissipation is performed inside the electrical box 100.
In some embodiments, referring to fig. 15, the control method of the air conditioner may further include: s108, the user shuts down, and the electrical components 112 in the electrical box 100 stop operating.
In some embodiments, referring to fig. 15, after the driving mechanism 160 drives the damper assembly 120 to rotate to the fourth opening angle, the method further comprises: and acquiring a detection result of the first temperature sensor, and if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner is lower than a fifth preset temperature T5, controlling the driving mechanism 160 to drive the air door assembly 120 to rotate to a third opening angle.
It should be noted that, if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the outdoor unit of the air conditioner, which is detected by the first temperature sensor, is still greater than the fifth preset temperature T5, the damper assembly 120 is not moved and remains at the fourth opening angle position.
For example, referring to fig. 15, after the damper assembly 120 rotates to the fourth opening angle, the temperature inside the electrical box 100 starts to decrease, and when the first temperature sensor detects that the temperature of the accommodating cavity 111 of the electrical box 100 is less than 35 ℃, the driving mechanism 160 is controlled to drive the damper assembly 120 to rotate to the position where the opening degree is 80 °, so as to reduce the air outlet area of the air outlet 131, and avoid that the normal operation of the electrical component 112 is affected due to too fast temperature decrease speed inside the electrical box 100.
In some embodiments, referring to fig. 15, after the drive mechanism 160 drives the damper assembly 120 to rotate to the third opening angle, the method further comprises: and acquiring a detection result of the first temperature sensor, and if the temperature Tn of the accommodating cavity 111 of the electrical box 100 of the air conditioner outdoor unit is less than a fourth preset temperature T4, controlling the driving mechanism 160 to drive the air door assembly 120 to rotate to a second opening and closing angle.
If the temperature Tn of the accommodating chamber 111 of the electrical box 100 of the outdoor unit of the air conditioner, which is detected by the first temperature sensor, is still higher than the fourth preset temperature T4, the damper assembly 120 is not moved and remains at the position of the third opening angle.
For example, referring to fig. 15, after the damper assembly 120 rotates to the third opening and closing angle, the temperature inside the electrical box 100 continues to decrease, and when the first temperature sensor detects that the temperature of the accommodating cavity 111 of the electrical box 100 is less than 25 ℃, the driving mechanism 160 is controlled to drive the damper assembly 120 to rotate to the position where the opening and closing degree is 40 °, so as to reduce the air outlet area of the air outlet 131, and avoid that the normal operation of the electrical component 112 is affected due to too fast temperature reduction speed inside the electrical box 100.
Referring to fig. 15, a specific embodiment of a control method of an air conditioner according to the present invention is described below, wherein the first preset temperature T1 is 40 ℃, the second preset temperature is 5 ℃, the third preset temperature is 15 ℃, the fourth preset temperature is 25 ℃, and the fifth preset temperature is 35 ℃; the first opening and closing angle is 120 degrees, the second opening and closing angle is 40 degrees, the third opening and closing angle is 80 degrees, and the fourth opening and closing angle is 120 degrees.
When the ambient temperature Tm is 41 ℃, the user turns on the air conditioner, the controller of the electrical box 100 obtains a power-on instruction, the second temperature sensor detects that the ambient temperature Tm is 41 ℃ and is higher than the first preset temperature T1, and then the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to a first opening and closing angle, namely 120 °, so as to rapidly cool the interior of the electrical box 100.
When the ambient temperature Tm drops to 35 ℃, the second temperature sensor detects that the ambient temperature Tm is 35 ℃, and then the ambient temperature Tm is greater than the second preset temperature T2 and less than the first preset temperature T1, then the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the second opening and closing angle, namely 40 °, to perform preliminary cooling to the inside of the electrical box 100.
As time goes on, the heat generated by the operation of the electrical component 112 inside the electrical box 100 heats the environment inside the electrical box 100, and when the first temperature sensor detects that the temperature Tn inside the accommodating cavity 111 of the electrical box 100 is greater than the fourth preset temperature T4, that is, the accommodating temperature is greater than 25 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the third opening angle, that is, 80 °, so as to further cool the inside of the electrical box 100.
When the electrical component 112 inside the electrical box 100 is operated for a long time and further heats the environment inside the electrical box 100, when the first temperature sensor detects that the temperature Tn inside the accommodating cavity 111 of the electrical box 100 is greater than the fifth preset temperature T5, that is, the temperature inside the accommodating cavity 111 is greater than 35 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the fourth opening and closing angle, that is, 120 °, to rapidly dissipate heat inside the electrical box 100.
When the air door assembly 120 performs rapid heat dissipation at the fourth opening angle, the temperature inside the electrical box 100 may drop, and when the first temperature sensor detects that the temperature Tn inside the accommodating cavity 111 of the electrical box 100 is less than the fifth preset temperature T5 and greater than the fourth preset temperature T4, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the third opening angle, that is, 80 °, so as to further perform heat dissipation on the electrical box 100.
When the air door assembly 120 further dissipates heat inside the electrical box 100 at the third opening angle, the temperature inside the electrical box 100 further decreases, and when the first temperature sensor detects that the temperature Tn inside the accommodating cavity 111 of the electrical box 100 is lower than the fourth preset temperature T4, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the second opening angle, namely 40 °, so as to further dissipate heat inside the electrical box 100.
Referring to fig. 15, the following is another embodiment of a control method of an air conditioner according to the present invention, in which a first preset temperature T1 is 40 ℃, a second preset temperature is 5 ℃, a third preset temperature is 15 ℃, a fourth preset temperature is 25 ℃, and a fifth preset temperature is 35 ℃; the first opening and closing angle is 120 degrees, the second opening and closing angle is 40 degrees, the third opening and closing angle is 80 degrees, and the fourth opening and closing angle is 120 degrees.
In winter, when the external temperature is 1 ℃, referring to fig. 4, when the second temperature sensor detects that the ambient temperature Tm is lower than the second preset temperature T2, the driving mechanism 160 is controlled to drive the air door assembly 120 to close the air outlet 131, and heat generated when the electrical component 112 inside the electrical box 100 operates heats the inside of the electrical box 100, so as to ensure the operating temperature of the electrical component 112.
The in-process of the inside electrical components 112 operation of electrical apparatus box 100 can produce the heat, the heat heats the chamber 111 that holds in the electrical apparatus box 100, make the temperature rise that holds chamber 111, when the temperature Tn that holds in the chamber 111 rises to 15 ℃, also the temperature Tn that holds in the chamber 111 is greater than the third and predetermines temperature T3, then control actuating mechanism 160 drive air door subassembly 120 rotates the second angle that opens and shuts, also be 40, to the inside preliminary cooling that carries on of electrical apparatus box 100.
As time goes on, the heat generated by the operation of the electrical component 112 inside the electrical box 100 heats the environment inside the electrical box 100, and when the first temperature sensor detects that the temperature Tn inside the accommodating cavity 111 of the electrical box 100 is greater than the fourth preset temperature T4, that is, the accommodating temperature is greater than 25 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the third opening angle, that is, 80 °, so as to further cool the inside of the electrical box 100.
When the electrical component 112 inside the electrical box 100 is operated for a long time and further heats the environment inside the electrical box 100, when the first temperature sensor detects that the temperature Tn inside the accommodating cavity 111 of the electrical box 100 is greater than the fifth preset temperature T5, that is, the temperature inside the accommodating cavity 111 is greater than 35 ℃, the driving mechanism 160 is controlled to drive the air door assembly 120 to rotate to the fourth opening and closing angle, that is, 120 °, to rapidly dissipate heat inside the electrical box 100.
