Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air conditioning system 100 provided in this embodiment in practical application.
The air conditioning system 100 provided in this embodiment includes the main unit 110 and the sub unit 120, both the main unit 110 and the sub unit 120 can independently exhaust air and suck air, the main unit 110 and the sub unit 120 are respectively disposed in two opposite side spaces of the target user 200 in the horizontal direction, and the sequential connection lines of the main unit 110, the target user 200 and the sub unit 120 define a first side space and a second side space at two opposite sides of the target user 200 in the horizontal direction.
The two opposite side spaces of the target user 200 in the horizontal direction refer to two spaces divided by an arbitrary horizontal straight line where the target user 200 is located, that is, the target user 200 is located between the master unit 110 and the slave unit 120. Two opposite sides of a track of the sequential connection line of the host 110, the target user 200 and the sub-machine 120 are a first side space and a second side space, the first side space is an area a in fig. 1, and the second side space is an area B in fig. 1.
It can be understood that the sequential connection lines of the master unit 110, the target user 200 and the slave unit 120 actually refer to the sequential connection lines among the respective horizontal centers of the master unit 110, the target user 200 and the slave unit 120, and taking the target user 200 as an example, the horizontal center refers to the center of the vertical projection of the target user 200 in the horizontal plane.
In this embodiment, the host 110, the target user 200 and the slave unit 120 are exactly in the same straight direction. In other embodiments, the master unit 110, the target user 200 and the slave unit 120 may not be in the same straight direction, as shown in fig. 2, and fig. 2 is a schematic structural diagram of an air conditioning system 100 according to another embodiment in practical application.
The main unit 110 is configured to discharge air to the first side space at a direction deviating from the first angle α of the target user 200, and absorb the discharged air of the sub-unit 120 by the second side space, and the sub-unit 120 is configured to discharge air to the second side space at a direction deviating from the second angle β of the target user 200, and absorb the discharged air of the main unit 110 by the first side space.
It should be noted that, the air is discharged to the first side space from the host 110 at a first angle away from the target user 200, which means that the air is discharged to the first side space at a first angle away from the horizontal center of the target user 200 at the viewing angle of the host 110. Similarly, the wind exits the sub-machine 120 to the second side space at a second angle away from the target user 200, which means the wind exits to the second side space at a second angle away from the horizontal center of the target user 200 at the viewing angle of the sub-machine 120.
Because the main unit 110 is deviated from the first angle of the target user 200 to output air to the first side space, the submachine 120 is deviated from the second angle of the target user 200 to output air to the second side space, the air output directions of the main unit 110 and the submachine 120 are both away from the target user 200, the direct blowing of the target user 200 is avoided, and the zero-wind-feeling effect is achieved.
The submachine 120 sucks air from the first side space and sucks the air outlet of the main machine 110; the main unit 110 sucks air from the second side space and sucks the air out of the sub unit 120. Therefore, the air returning and returning of the main unit 110 and the sub unit 120 form a circulation flow path surrounding the target user 200, the air returning and returning of the main unit 110 is prevented from being wasted due to the large-range diffusion of the air returning of the main unit 110 in the first side space, the air returning and returning of the sub unit 120 in the second side space are prevented from being wasted due to the large-range diffusion of the air returning of the sub unit 120, the air temperature in the area surrounded by the circulation flow path is changed rapidly and sufficiently, and the comfort level of the target user 200 is remarkably improved.
In this embodiment, the master unit 110 and the slave unit 120 both have heating and cooling functions, that is, they suck air back and then exchange heat to blow out the air. In other embodiments, only the master unit 110 may have a heat exchange function, and the slave unit 120 may only function to relay the airflow.
Referring to fig. 3 and 4 in combination, fig. 3 is a schematic structural diagram of the host 110 in a first view, and fig. 4 is a schematic structural diagram of the host 110 in a second view.
In this embodiment, the main body 110 includes a first body 111 and a first base 112, the first body 111 is rotatably disposed on the first base 112, and the first body 111 is respectively provided with a first air outlet 113 and a first air inlet 114. The extending direction of the first air outlet 113 and the first air inlet 114 forms an included angle, and in the process that the first body 111 rotates relative to the first base 112, the first air outlet 113 is driven to rotate to a direction deviating from the first angle of the target user 200 to output air to the first side space.
It can be understood that, in order to ensure that the first air inlet 114 can suck air from the second side space when the first air outlet 113 discharges air to the first side space in the direction deviating from the first angle of the target user 200, the first angle needs to be smaller than the included angle between the air discharging direction of the first air outlet 113 and the air inlet direction of the first air inlet 114, otherwise, the first air inlet cannot form a circulation flow path after being turned into the first side space to suck air.
Considering that too large included angle between the air outlet direction of the first air outlet 113 and the air inlet direction of the first air inlet 114 will make it difficult to form a circulation flow path with the submachine 120, and too small included angle between the two will easily make the air outlet of the first air outlet 113 sucked back by the first air inlet 114. In this embodiment, an included angle θ between the air outlet direction of the first air outlet 113 and the air inlet direction of the first air inlet 114 is between 45 ° and 180 °.
Referring to fig. 5 and fig. 6 in combination, fig. 5 is a schematic structural diagram of the handset 120 at a third viewing angle, and fig. 6 is a schematic structural diagram of the handset 120 at a fourth viewing angle.
In this embodiment, the sub-machine 120 includes a second machine body 121 and a second base 122, the second machine body 121 is rotatably disposed on the second base 122, and the second machine body 121 is respectively disposed with a second air outlet 123 and a second air inlet 124. The second air outlet 123 forms an included angle with the extending direction of the second air inlet 124, and in the process that the second body 121 rotates relative to the second base 122, the second air outlet 123 is driven to rotate to the direction deviating from the second angle of the target user 200 to output air to the second side space.
It can be understood that, in order to ensure that the second air outlet 123 blows air to the second side space in a direction deviating from the second angle of the target user 200, the second air inlet 124 can suck air from the first side space, and it needs to be satisfied that the second angle is smaller than an included angle between the air outlet direction of the second air outlet 123 and the air inlet direction of the second air inlet 124, otherwise, the second air inlet is turned into the second side space and cannot form a circulation flow path after sucking air.
Considering that an excessively large included angle between the air outlet direction of the second air outlet 123 and the air inlet direction of the second air inlet 124 will make it difficult to form a circulation flow path with the host 110, and an excessively small included angle therebetween will make the air outlet of the second air outlet 123 be sucked back by the second air inlet 124. In this embodiment, an included angle Φ between the air outlet direction of the second air outlet 123 and the air inlet direction of the second air inlet 124 is between 45 ° and 180 °.
In addition, in this embodiment, the main unit 110 is provided with a first detecting element for detecting the position of the target user 200, and the main unit 110 is configured to control the first body 111 to rotate relative to the first base 112 according to a detection result of the first detecting element, so that the first air outlet 113 exhausts air to the first side space in a direction deviating from the first angle of the target user 200.
The secondary machine 120 is provided with a second detection piece for detecting the position of the target user 200, and the secondary machine 120 is configured to control the second body 121 to rotate relative to the second base 122 according to a detection result of the second detection piece, so that the second air outlet 123 exhausts air to the second side space in a direction deviating from the second angle of the target user 200.
In practical applications, the first detecting member and the second detecting member may employ an image sensor or a thermal sensor. Since the human body has a body shape substantially symmetrical about the center in any horizontal direction, the first angle and the second angle are substantially equal in this embodiment.
The embodiment further provides a single-person surround type air conditioning method, which is applied to the host 110 in the air conditioning system 100. Referring to fig. 7, fig. 7 is a block diagram illustrating a flow chart of the single-person surround type air conditioning method, the single-person surround type air conditioning method including the steps of:
step S101, obtaining included angles respectively formed by the host 110 and a connection line between the horizontal center of the target user 200 and the horizontal end of the target user 200.
In this embodiment, the first detecting element disposed on the host 110 is actually a first image sensor, the first image sensor includes a first pixel array 115, and the step S101 includes the sub-steps as shown in fig. 8:
in sub-step S1011, a first pixel region 1151 occupied by the target user 200 in the first pixel array 115 is acquired.
In sub-step S1012, a horizontal coordinate difference between the center pixel point and the horizontal end pixel point of the first pixel region 1151 is calculated.
In sub-step S1013, the ratio of the horizontal coordinate difference to the length of the first pixel array 115 in the horizontal direction is calculated.
And a substep S1014, calculating the product of the horizontal detection angle of the first image sensor and the ratio to obtain the included angle.
Referring to fig. 9 and 10 in combination, fig. 9 is a schematic diagram illustrating relative positions of the host 110 and the target user 200, and fig. 10 is a schematic diagram illustrating that the target user 200 occupies the first pixel area 1151 in the first pixel array 115.
Substep S1011 is a process of detecting the target user 200 by the first image sensor, and an x-y coordinate system is established by using any one pixel point of the first pixel array 115 as a coordinate origin, all pixel points in the first pixel region 1151 can be calibrated by the coordinate system, and a value of an x axis represents a horizontal coordinate of each pixel point.
The center pixel point of the first pixel region 1151 is the C pixel point in fig. 10, and its coordinate is (4,4), the horizontal end pixel point of the first pixel region 1151 is the D pixel point and the E pixel point in fig. 10, the coordinate of the D pixel point is (2,4), and the coordinate of the E pixel point is (6,4). Since the distance between the C pixel and the D pixel in the horizontal direction is equal to the distance between the C pixel and the E pixel, the horizontal coordinate difference between the C pixel and the D pixel or the E pixel may be calculated in the sub-step S1012, and the absolute value of the horizontal coordinate difference is 2.
The length of the first pixel array 115 in the horizontal direction refers to the total number of pixels at two ends of the first pixel array 115 in the coordinate system, and in this embodiment, the total number is 12. Therefore, the calculation result of the substep S1013 is 1/6.
The central pixel point corresponds to the horizontal center of the target user 200, the horizontal end pixel point corresponds to the horizontal end of the target user 200, the occupation ratio of an included angle gamma which is formed by the host 110 and a connecting line between the horizontal center of the target user 200 and the horizontal end of the target user 200 in the horizontal detection angle delta of the first image sensor is equal to 1/6, and the horizontal detection angle of the first image sensor can be directly read from the specification parameters.
Therefore, in the sub-step S1014, the angle formed by the host 110 and the connection line between the horizontal center of the target user 200 and the horizontal end of the target user 200 can be obtained by multiplying the horizontal detection angle of the first image sensor by 1/6.
With continued reference to fig. 7, the single-person surround type air conditioning method may further include the steps of:
step S102, calculating the product of the included angle and a preset correction coefficient to obtain a first angle.
The value of the correction coefficient is greater than 1, and a value of 1.1 is preferred in this example. The larger the correction coefficient is, the larger the degree of the deviation of the air outlet of the host 110 from the target user 200 is, the specific numerical value of the correction coefficient is set by the user according to the user experience, and the angle of the deviation of the air outlet of the host 110 from the target user 200, namely the first angle α, can be obtained by calculating the product of the included angle γ and the correction coefficient.
In step S103, the control host 110 discharges air toward the first lateral space in a direction deviating from the horizontal center of the target user 200 by a first angle, and sucks air from the second lateral space.
In order to ensure that the first air inlet 114 can suck air from the second lateral space when the first air outlet 113 discharges air to the first lateral space in a direction deviating from the first angle α of the target user 200, it is required to satisfy that the first angle α is smaller than an included angle θ between the air discharging direction of the first air outlet 113 and the air inlet direction of the first air inlet 114.
Step S104, sending the correction coefficient to the handset 120, so that the handset 120 blows air out toward the second side space in a direction deviating from the horizontal center of the target user 200 by a second angle, and sucks air from the first side space.
The master unit 110 calculates the first angle from the correction coefficient and transmits the correction coefficient to the slave unit 120, and since the human body has a substantially central symmetry in any horizontal direction, the same correction coefficient is used to calculate the second angle equal to the first angle. That is, the retraction angle of the master unit 110 is equal to the retraction angle of the slave unit 120, and the stability of the circulation flow path can be further improved.
The embodiment further provides a single-person surrounding type air conditioning method, which is applied to the sub-unit 120 in the air conditioning system 100. Referring to fig. 11, fig. 11 is a block diagram illustrating a flow of the single-person surround type air conditioning method, which includes the following steps:
step S201, obtaining the included angles enclosed by the sub-machine 120 and the connecting line between the horizontal center of the target user 200 and the horizontal end of the target user 200.
In this embodiment, the second detecting element disposed on the sub-unit 120 is actually a second image sensor, the second image sensor includes a second pixel array 125, and the step S201 includes the sub-steps shown in fig. 12:
in sub-step S2011, a second pixel region 1251 occupied by the target user 200 in the second pixel array 125 is obtained.
In sub-step S2012, a horizontal coordinate difference between a center pixel point and a horizontal end pixel point of the second pixel region 1251 is calculated.
In sub-step S2013, the ratio of the horizontal coordinate difference to the length of the second pixel array 125 in the horizontal direction is calculated.
And a substep S2014 of calculating the product of the horizontal detection angle of the second image sensor and the ratio to obtain the included angle.
Referring to fig. 13 and 14 in combination, fig. 13 is a schematic diagram illustrating a relative position between the slave unit 120 and the target user 200, and fig. 14 is a schematic diagram illustrating the target user 200 occupying the second pixel area 1251 in the second pixel array 125.
Substep S2011 is a process of detecting the target user 200 by the second image sensor, and an x-y coordinate system is established by using any one pixel point of the second pixel array 125 as a coordinate origin, all pixel points in the second pixel region 1251 can be calibrated by the coordinate system, and a value of an x axis represents a horizontal coordinate of each pixel point.
The center pixel point of the second pixel region 1251 is the F pixel point in fig. 14, and its coordinate is (4,4), the horizontal end pixel point of the second pixel region 1251 is the G pixel point and the H pixel point in fig. 14, the coordinate of the G pixel point is (2,4), and the coordinate of the H pixel point is (6,4). Since the distance between the F pixel and the G pixel in the horizontal direction is equal to the distance between the F pixel and the H pixel, the horizontal coordinate difference between the F pixel and the G pixel or the H pixel can be calculated in sub-step S2012, and the absolute value of the horizontal coordinate difference is 2.
The length of the second pixel array 125 in the horizontal direction refers to the total number of pixels at two ends of the second pixel array 125 in the coordinate system, and in this embodiment, the total number is 12. Therefore, the calculation result of the substep S2013 is 1/6.
The central pixel point corresponds to the horizontal center of the target user 200, the horizontal end pixel point corresponds to the horizontal end of the target user 200, the occupation ratio of the included angle epsilon formed by the sub-machine 120 and the connecting line between the horizontal center of the target user 200 and the horizontal end of the target user 200 in the horizontal detection angle zeta of the second image sensor is equal to 1/6, and the horizontal detection angle of the second image sensor can be directly read from the specification parameters.
Therefore, in the sub-step S2014, the angle ∈ between the sub-unit 120 and the connection line between the horizontal center of the target user 200 and the horizontal end of the target user 200 can be obtained by calculating the horizontal detection angle of the second image sensor multiplied by 1/6.
With continued reference to fig. 11, the single-person surround type air conditioning method may further include the steps of:
in step S202, the correction coefficient sent from the host 110 is received.
The correction coefficient is preferably 1.1.
Step S203, calculating the product of the included angle and the correction coefficient to obtain a second angle.
The product of the included angle epsilon and the correction coefficient 1.1 is calculated to obtain the angle of the air outlet of the submachine 120 deviating from the target user 200, namely a second angle beta, and the numerical value of the second angle beta is equal to the first angle alpha.
In step S204, the sub-unit 120 is controlled to discharge air toward the second side space in a direction deviating from the horizontal center of the target user 200 by a second angle, and to suck air from the first side space.
In order to ensure that the second air inlet 124 can suck air from the first lateral space when the second air outlet 123 discharges air to the second lateral space at a second angle β away from the target user 200, it is required that the second angle β is smaller than an included angle Φ between the air discharging direction of the second air outlet 123 and the air inlet direction of the second air inlet 124.
In summary, the air inlet and outlet of the main unit 110 and the sub-unit 120 form a circulation flow path and surround the target user 200, so that the waste of the air outlet of the main unit 110 in the first side space and the waste of the air outlet of the sub-unit 120 in the second side space are prevented, and the waste of energy consumption is avoided while the air outlet is directly blown to the user.
Therefore, the air conditioning system 100 and the single-person surrounding type air conditioning method provided by the embodiment of the invention can realize zero-wind-sense air outlet, and can improve the comfort of users and reduce energy consumption.
