When gaps are formed between the upper and lower wind sweeping blades 51 and the left volute, and gaps are not formed between the upper and lower wind sweeping blades 51 and the right volute, the left and right wind sweeping blades positioned on the left side of the air duct 4 correspond to the gaps; when gaps are formed between the upper and lower wind sweeping blades 51 and the right volute, and gaps are not formed between the upper and lower wind sweeping blades 51 and the left volute, the left and right wind sweeping blades positioned on the right side of the air duct 4 correspond to the gaps; when a gap (first gap) is formed between the upper and lower wind sweeping blades 51 and the left volute, and a gap (second gap 7) is also formed between the upper and lower wind sweeping blades 51 and the right volute, the left and right wind sweeping blades located on the left side of the air duct 4 correspond to the first gap, and the left and right wind sweeping blades located on the right side of the air duct 4 correspond to the second gap 7.
In the air duct 4, the up-down wind sweeping mechanism 100 is located at the upstream of the left-right wind sweeping mechanism 200, the air flow entering the air duct 4 from the air inlet of the air duct 4 first passes through the up-down wind sweeping mechanism 100, the up-down wind sweeping mechanism 100 is used for shunting wind, and the rotation angle of the up-down wind sweeping blade 51 is adjusted to adjust the air volume of the air supplied from the up-down wind sweeping mechanism 100 to the left-right wind sweeping mechanism 200. The number of the left and right wind sweeping blades is at least two, and the left and right wind sweeping blades 9 and 12 are respectively, a gap is formed between the left side and the right side of the air duct 4, and the size of the gap is changed when the left and right wind sweeping mechanism 200 is started, so that the direction of wind blowing to a user is changed when the rotation angle of the first left and right wind sweeping blades is adjusted. The air output is adjusted by the operation of the up-down air sweeping mechanism 100, and then the air is guided by the left-right air sweeping blades 51, and the left-right air sweeping blades positioned at the left side and/or the right side of the air duct 4 correspond to the gaps, so that the air blown out from the gaps is guided between the left-right air sweeping blades and the corresponding air duct side, when a user stands right in front of the air outlet 8, the air flow flowing out from the gaps can be blown out from the left side and/or the right side of the air outlet, thereby realizing side air outlet without causing the air blown out from the left-right air sweeping blades to be all blown to the user.
Preferably, gaps are formed between the left and right air sweeping blades 51 and the left and right sides of the air duct 4, the first gap is formed between the left and right air sweeping blades 51 and the air duct 4, that is, between the left and right air sweeping blades 51 and the left volute 2, and a second gap 7 is formed between the right air sweeping blades 51 and the right air duct 4, that is, between the right volute 3, and when the air conditioner is started, the positions of the upper and lower air sweeping mechanisms in the air duct are adjusted by the rotation of the upper and lower air sweeping blades, so that the air flow blown from the first gap is guided between the left and right air sweeping blades and the left volute 2, flows out of the air outlet 8 of the air duct 4, and deflects outwards (that is, deflects outwards from the left and right air sweeping blades 8) of the air conditioner; the air flow blown out from the second gap is guided between the left and right sweeping blades and the right volute 3 by the left and right sweeping blades positioned on the right side of the air duct 4, flows out from the air outlet 8 of the air duct 4 and deflects towards the outer side of the air conditioner (namely deflects towards one side of the air outlet 8 away from the left and right sweeping blades), so that multidirectional air supply is realized, the phenomenon that user experience such as supercooling or overheating is poor due to direct blowing of high-speed high-pressure air flow onto a user can be effectively solved, and the comfort of use and the air supply selectivity are improved.
In a preferred embodiment, the width of the first gap ranges from 7.5mm to 15mm, and if the width of the second gap 7 ranges from 2mm to 10mm; preferably, the width of the first gap is 8mm, and the width of the second gap 7 is 6mm.

The up-down wind sweeping mechanism 100 further comprises a driving device, and the driving device is connected with the up-down wind sweeping blades 51 to drive the up-down wind sweeping blades 51 to rotate synchronously. When the up-down sweeping mechanism 100 is triggered, the driving device is started, and under the driving action of the driving device, the plurality of up-down sweeping blades simultaneously rotate in the same direction and at the same speed.
The left and right wind sweeping mechanism 200 further comprises a plurality of driving mechanisms, and the driving mechanisms are connected with the left and right wind sweeping blades in a one-to-one correspondence manner so as to drive the left and right wind sweeping blades to rotate independently. Each left and right wind sweeping blade is provided with an independent driving mechanism, the air conditioner can send out the same control instruction to the plurality of driving mechanisms, and can also send out different control instructions, namely the rotation directions, angles and speeds of the plurality of left and right wind sweeping blades can be all the same, can also be different, and can also be not identical.
The driving device comprises a motor, a linkage mechanism and a plurality of connecting rods 5, and the connecting rods 5 are in one-to-one correspondence with the upper and lower wind sweeping blades 51; the motor is connected with the linkage mechanism, and the motor and the linkage mechanism are both arranged on the outer side of the left volute; one end of the connecting rod 5 is connected with the linkage mechanism, and the other end of the connecting rod penetrates through the left volute to be connected with the upper and lower sweeping blades. When the motor is started, the linkage mechanism drives the connecting rod 5 to rotate relative to the left volute 2, so that the upper and lower wind sweeping blades 51 are driven to rotate in the air duct 4, and the air supply quantity is controlled.
The left and right wind sweeping blades are strip-shaped wind sweeping blades, the length directions of the left and right wind sweeping blades are parallel to the length direction of the air outlet 8, and the left and right wind sweeping blades are sequentially arranged along the width direction of the air outlet 8.
The plurality of upper and lower wind sweeping blades 51 are sequentially arranged in the air duct 4 along the up-down direction and are arranged at intervals; when the up-down wind sweeping mechanism is started, the up-down wind sweeping blades 51 synchronously rotate to a closed state. Taking the upper and lower wind sweeping blades 51 as a flat plate, when the upper and lower wind sweeping blades 51 are in a closed state, the upper and lower wind sweeping blades 51 are positioned on the same plane, and a gap is formed between two adjacent upper and lower wind sweeping blades so as to facilitate the turnover of the upper and lower wind sweeping blades; taking the upper and lower wind sweeping blades 51 as an example, when the upper and lower wind sweeping blades 51 are in a closed state, the openings of the upper and lower wind sweeping blades 51 are in the same plane, a gap is formed between two adjacent upper and lower wind sweeping blades so as to facilitate the turnover of the upper and lower wind sweeping blades, at this time, the upper and lower wind sweeping blades form a vertical row from top to bottom in the air duct, the positions of the upper and lower wind sweeping blades 51 in the air duct 4 are covered by the upper and lower wind sweeping blades 51, and the air flow entering from the air inlet of the air duct 4 is split, namely the upper and lower wind sweeping blades 51 divide the air duct into two air ducts: a first air supply channel and a second air supply channel. The width of the gap ranges from 3mm to 6mm, and the first air supply channel is formed by the first gap and the second gap 7; the second air supply passage is formed by the at least one air passage hole.
When the plurality of up-down wind sweeping blades 51 are in a closed state, the plurality of up-down wind sweeping blades 51 cover positions of the plurality of up-down wind sweeping blades 51 in the air duct, at the moment, the air flow intensity of the air flowing from the up-down wind sweeping mechanism 100 to the left-right wind sweeping mechanism 200 is lowest, further, the width of the air passing hole is smaller than the width of the first gap and smaller than the width of the second gap 7, so that the air flow intensity of the air flowing from the first air supply channel to the left-right wind sweeping mechanism 200 is smaller than the air flow intensity of the air flowing from the second air supply channel to the left-right wind sweeping mechanism 200, and the air flowing from the second air supply channel to the left-right wind sweeping blades located on the left side of the air duct 4 and the left-right wind sweeping blades located on the right side of the air duct are blown to users, and based on the number calculation, the air flowing from the air passing hole 52 is in a supercooled state, thereby the air flowing from the first air supply channel to the left-right wind sweeping mechanism 200 is smaller than the air flow intensity of the air flowing from the second air supply channel to the left-right wind sweeping mechanism 200, and the air flowing from the left-right wind sweeping mechanism is blown from the left-right wind channel to the left wind sweeping blades of the user is blown from the left-right wind direction of strong wind user, and the user is blown from the left wind of strong wind source to the user, and the user is blown from the left wind on the left wind source to the left wind blade on the left wind mechanism, and the wind source 200.
When the air conditioner stops, all the left and right wind sweeping blades rotate to the width direction parallel to the width direction of the air outlet 8, and the left and right wind sweeping blades cover the position of the air outlet 8, namely, the left and right wind sweeping blades are in a closed state.
The invention also provides an air supply control method of the air conditioner, as shown in fig. 2, comprising the following steps:
s100, controlling the upper and lower wind sweeping blades 51 to rotate to a closed state.
The upper and lower wind-sweeping blades 51 are rotated to a closed state, so that the overall strength of the air flow blown to the left and right wind-sweeping mechanisms 200 through the upper and lower wind-sweeping mechanisms 100 is minimized. When the upper and lower wind sweeping blades 51 are in a closed state, the minimum distance between the upper and lower wind sweeping blades and the left and right wind sweeping mechanisms is 40mm.
Specifically, the step S100 includes the following steps:
s101, starting the upper and lower wind sweeping mechanism 100, wherein the upper and lower wind sweeping blades 51 synchronously rotate;
the air conditioner sends an instruction to the driving device, so that the driving device drives the plurality of upper and lower sweeping blades to synchronously rotate.
S102, when the upper and lower wind sweeping blades 51 rotate to a closed state, the upper and lower wind sweeping blades cover the air channels where the upper and lower wind sweeping blades are located.
The intensity of the air flow flowing to the left and right wind sweeping mechanisms 200 can be adjusted by the rotation of the plurality of upper and lower wind sweeping blades; when the upper and lower scan blades 51 rotate to a closed state, a gap is formed between two adjacent upper and lower scan blades, and the width of the gap is 3 mm-6 mm. In the present invention, the gap only provides a rotation space for the upper and lower scan blades, so that two adjacent upper and lower scan blades do not interfere with each other during rotation, and when the air conditioner is started and the upper and lower scan blades 51 rotate to a closed state, the air flow passing through the gap is ignored in the present invention. The upper and lower wind sweeping blades 51 cover the positions of the wind channel 4, so that when the air flow passes through the upper and lower wind sweeping blades 51, the air flow can only pass through the gaps, and the intensity of the air flow flowing to the left and right wind sweeping mechanism 200 is minimized.
S200, controlling the left and right wind sweeping blades corresponding to the gaps to rotate to a preset state.
The left and right wind sweeping blades rotate, when a gap is formed between the upper and lower wind sweeping blades 51 and the left volute 2, the left and right wind sweeping blades positioned at the left side of the air duct 4 correspond to the gap, and the left and right wind sweeping blades are controlled to rotate to a preset state; when a gap is formed between the upper and lower wind sweeping blades 51 and the right volute 3, the left and right wind sweeping blades positioned on the right side of the air duct 4 correspond to the gap, and the left and right wind sweeping blades are controlled to rotate to a preset state; when the first gap is formed between the upper and lower wind sweeping blades 51 and the left volute 2 and the second gap 7 is formed between the upper and lower wind sweeping blades and the right volute 3, the left and right wind sweeping blades positioned on the left side of the air duct 4 and the left and right wind sweeping blades positioned on the right side of the air duct 4 are controlled to rotate to a preset state.
The step S200 specifically includes:
and controlling the left and right wind-sweeping blades corresponding to the gap to rotate a preset angle towards one side of the wind channel corresponding to the left and right wind-sweeping blades close to the wind outlet of the wind channel so as to enable the left and right wind-sweeping blades to be in a preset state.
Preferably, gaps are formed between the upper and lower wind sweeping blades 51 and the left and right sides of the air duct 4, that is, the first gaps are formed between the upper and lower wind sweeping blades 51 and the left volute 2, the second gaps 7 are formed between the upper and lower wind sweeping blades 51 and the right volute 3, and the first gaps and the second gaps form the first air supply channel. The preset state refers to: the left and right wind-sweeping blades positioned on the left side of the air duct 4 rotate towards the left side of the air duct 4 by a first preset angle relative to the central axis line of the air duct 4 air outlet 8, and the left and right wind-sweeping blades positioned on the right side of the air duct 4 rotate towards the right side of the air duct 4 by a second preset angle relative to the central axis line of the air duct 4 air outlet 8.
The value ranges of the first preset angle and the second preset angle are 35-60 degrees.
S300, the first wind beam passing through the gap is guided between the left and right wind-sweeping blades corresponding to the gap and one sides of the air outlet 8 of the air duct 4 corresponding to the left and right wind-sweeping blades, and flows out of the air outlet 8 of the air duct 4 and deflects to the outer side of the air conditioner.
The air flow flowing out from the first gap is guided by left and right scavenging blades positioned at the left side of the air duct 4 to flow out between the left and right scavenging blades and the left volute; the air flow flowing out from the second gap 7 is guided by the left and right wind-sweeping blades positioned on the right side of the air duct 4 to flow out between the left and right wind-sweeping blades and the right volute. The outside of the air conditioner is the outside of the air conditioner opposite to the air outlet 8, i.e. the left side of the outside of the air outlet 8 and the right side of the outside of the air outlet 8.
