[0040] Please refer to Figure 1 The air supply device in one embodiment includes an air supply mechanism 100 and a movable platform 200. The air supply mechanism 100 is used for supplying air, and the movable platform 200 is used for driving the air supply mechanism 100 to move.

[0041] Among them, the mobile platform 200 includes a fixed base 210, a first moving mechanism 220 and a second moving mechanism 230. The first moving mechanism 220 is connected to the air supply mechanism 100 and is used to drive the air supply mechanism 100 to move along a first direction. The second moving mechanism 230 is connected to the first moving mechanism 220, and the second moving mechanism 230 is slidably disposed on the fixed base 210 to drive the air supply mechanism 100 to move along a second direction, and the second direction is perpendicular to the first direction.

[0042] It should be noted that in this embodiment, the outside air is converted into cold air after heat exchange with the evaporator of the air conditioning unit, and the cold air is blown to the place to be heat exchanged through the air supply mechanism 100. If the position of the air supply mechanism 100 is fixed, it is very easy to make the local wind speed too high during the air supply process, which will blow the cold air out of the place to be heat exchanged, reducing the heat exchange efficiency.

[0043] Through the above arrangement, the mobile platform 200 can drive the air supply mechanism 100 to move, thereby changing the position of the air supply mechanism 100, thereby adjusting the wind field position; the wind field position can be flexibly adjusted according to demand, and the air supply is more uniform during the drainage air supply, which is beneficial to improving the heat exchange efficiency of the place to be heat exchanged.

[0044] In a specific embodiment, the first direction is the vertical direction (i.e. Figure 1The second direction is the horizontal direction (ie Figure 1 X direction as shown).

[0045] like Figure 1 In the illustrated embodiment, the first moving mechanism 220 includes a first driving member 221, a gear 222 and a rack 223, and the rack 223 is slidably disposed on the fixing seat 210. The gear 222 is meshed with the rack 223, and the first driving member 221 is fixed to the air supply mechanism 100, and the first driving member 221 is used to drive the gear 222 to roll on the rack 223 along the first direction.

[0046] It should be noted that the output shaft of the first driving member 221 is connected to the gear 222. Driven by the first driving member 221, since the rack 223 is fixed in the first direction, the gear 222 rolls on the rack 223 along the first direction, thereby driving the air supply mechanism 100 to move along the first direction, so that the position of the air supply mechanism 100 in the first direction is adjustable.

[0047] In other embodiments, the rack 223 may be replaced by a chain, and the gear 222 may be replaced by a gear shaft.

[0048] In a specific implementation, the first driving member 221 is a motor or a cylinder.

[0049] like Figure 1 In the illustrated embodiment, the second moving mechanism 230 includes a second driving member (not shown), a roller 231 and a guide rail 232. The guide rail 232 is fixed to the fixed base 210 and is arranged along the second direction. At least one roller 231 is provided at each end of the rack 223. The second driving member is used to drive the roller 231 to slide on the guide rail 232 along the second direction.

[0050] It can be understood that the output shaft of the second driving member is connected to the roller 231. Driven by the second driving member, the roller 231 will slide along the second direction on the guide rail 232, and drive the rack 223 to slide along the second direction. Since the rack 223 is meshed with the gear 222, the rack 223 drives the air supply mechanism 100 to slide along the second direction, so that the position of the air supply mechanism 100 in the second direction is adjustable.

[0051] In a specific embodiment, the second driving member is a motor or a cylinder.

[0052] In this embodiment, a roller 231 is provided at each end of the rack 223. In other embodiments, multiple rollers 231 may be provided at each end of the rack 223, and the rollers 231 at the same end are arranged side by side along the second direction, so that the rollers 231 are not easily skewed when sliding on the guide rail 232.

[0053] In this embodiment, the roller 231 is rotatably connected to the end of the rack 223 via a pin. In other embodiments, the end of the rack 223 may have a connecting shaft, and the roller 231 is rotatably disposed on the connecting shaft.

[0054] In this embodiment, the guide rail 232 is fixed to the guide rail 232 by screws or bolts. In other embodiments, the guide rail 232 and the fixing seat 210 can also be an integrally formed structure with high mechanical strength and good integrity.

[0055] As shown in the embodiment, the air supply device further includes a controller (not shown), which is electrically connected to the first driving member 221 and the second driving member and is used to control the operation of the first driving member 221 and the second driving member.

[0056] Through this configuration, the moving distances of the first moving mechanism 220 and the second moving mechanism 230 can be accurately controlled by the controller, and the position adjustment accuracy of the air supply mechanism 100 in the first direction and the second direction is higher.

[0057] In a specific embodiment, a position sensor (not shown) may be provided on the air supply mechanism 100, and the position sensor is electrically connected to the controller. The position sensor detects the position of the air supply mechanism 100 and generates a corresponding position signal, and the controller controls the operation of the first driving member 221 and the second driving member according to the position signal.

[0058] like Figure 1 In the illustrated embodiment, the air supply mechanism 100 includes a fan 110 and a flow guide 120 , the first moving mechanism 220 is connected to the fan 110 , and the fan 110 is disposed at an air inlet of the flow guide 120 .

[0059] In this embodiment, the first driving member 221 of the first moving mechanism 220 is fixedly connected to the fan 110, and the fan 110 has an air inlet end and an air outlet end, and the air outlet end of the fan 110 is connected to the air inlet of the guide member 120. The airflow enters from the air inlet end and is output from the air outlet end to the air inlet of the guide member 120, and finally is output from the air outlet of the guide member 120 to the place to be heat exchanged. In this embodiment,.

[0060] In a specific embodiment, the fan 110 is an axial flow fan or a mixed flow fan.

[0061] like Figure 1 In the illustrated embodiment, the air guide 120 includes an air guide cover 121, a first mounting plate 122 and a second mounting plate 123. The first mounting plate 122 is provided with a first ventilation hole 124, the second mounting plate 123 is provided with a second ventilation hole 125, and the two ends of the air guide cover 121 are respectively provided at the first ventilation hole 124 and the second ventilation hole 125.

[0062] In this embodiment, the first end of the air deflector 121 is connected to the first mounting plate 122 and covers at least the first ventilation hole 124 , and the second end of the air deflector 121 is connected to the second mounting plate 123 and covers at least the second ventilation hole 125 .

[0063] This arrangement can prevent air leakage at the intersection of the first end of the air deflector 121 and the first ventilation hole 124 and at the intersection of the second end of the air deflector 121 and the second ventilation hole 125, thereby affecting the air supply effect.

[0064] In a specific embodiment, the first end of the air deflector 121 is fixed to the first mounting plate 122 by a sealant, and the second end of the air deflector 121 is fixed to the second mounting plate 123 by a sealant. In other embodiments, the first end of the air deflector 121 is detachably mounted on the first mounting plate 122, and the second end of the air deflector 121 is detachably mounted on the second mounting plate 123, which facilitates the reuse of the air deflector 121.

[0065] like Figure 1 In the embodiment shown, the air deflector 121 is hollow, and the cross-sectional area of ​​the air inlet of the air deflector 121 is smaller than the cross-sectional area of ​​the air outlet of the air deflector 121. With this arrangement, the airflow can flow from the air inlet of the air deflector 121 to the air outlet of the air deflector 121 quickly and smoothly.

[0066] In this embodiment, the aperture of the first ventilation hole 124 is smaller than the aperture of the second ventilation hole 125 .

[0067] In a specific implementation, the air guide cover 121 is made of canvas, silica gel or other deformable soft materials.

[0068] like Figure 1 In the illustrated embodiment, the air guide 120 further includes a plurality of support ribs 126 , two ends of the support ribs 126 are respectively connected to the first mounting plate 122 and the second mounting plate 123 , and each support rib 126 is disposed around the outer periphery of the air guide cover 121 .

[0069] Through this arrangement, when the air supply mechanism 100 supplies air, the support ribs 126 can support the limiting air guide cover 121 to prevent the air guide cover 121 from deforming and collapsing and failing to effectively supply air.

[0070] In this embodiment, both ends of the support rib 126 are welded to the first mounting plate 122 and the second mounting plate 123. In other embodiments, both ends of the support rib 126 can also be detachably connected to the first mounting plate 122 and the second mounting plate 123.

[0071] In this embodiment, the support ribs 126 are arranged at intervals along the same direction on the outer periphery of the air deflector 121. In other embodiments, the support ribs 126 can also be distributed on the outer periphery of the air deflector 121 in a cross-staggered manner.

[0072] like Figure 1 In the illustrated embodiment, the air supply device further includes a first sensor (not shown), which is disposed at the air outlet of the air guide cover 121 and is used to detect the wind speed.

[0073] It should be noted that in this embodiment, the wind speed at the center of the air outlet of the air deflector 121 is detected, and the wind speed at the center of the air outlet of the air deflector 121 is compared with the preset wind speed. In other embodiments, the wind speeds at multiple points at different positions of the air outlet of the air deflector 121 can also be detected, and the wind speeds at multiple positions are coupled into an average wind speed, and the average wind speed is compared with the preset wind speed.

[0074] Please refer to Figure 1 , a control method of an air supply device in an embodiment includes:

[0075] S1, detecting the wind speed V at the air outlet of the air supply device;

[0076] S2, comparing the speed of the air outlet with the preset wind speed Va;

[0077] S3. According to the comparison result between the wind speed V at the air outlet and the preset wind speed Va, it is determined whether the air supply device moves along the first direction and / or along the second direction.

[0078] Through the above arrangement, the position of the air supply device can be changed, thereby adjusting the wind field position; the wind field position can be flexibly adjusted according to demand, and the air supply is more uniform during drainage, which is beneficial to improving the heat exchange efficiency of the place to be heat exchanged.

[0079] like Figure 1 In the illustrated embodiment, step S3 is specifically as follows:

[0080] When the wind speed V at the air outlet is equal to the preset wind speed Va, the air supply device does not move;

[0081] When the wind speed V at the air outlet is greater than or less than the preset wind speed Va, the air supply device is controlled to move along the first direction and / or along the second direction. After the movement, the wind speed V at the air outlet of the air supply device is detected again, and the speed V of the air outlet is compared with the preset wind speed Va to determine whether the air supply device moves along the first direction and / or along the second direction until V is equal to Va.

[0082] Wherein, the moving distance of the air supply device along the first direction and / or along the second direction is ((Va-V) / V)*5 cm.

[0083] It should be noted that the wind speed V at the air outlet includes a first component speed V1 in the first direction and a component speed V2 in the second direction. The first component speed V1 and the component speed V2 in the second direction need to be compared with the preset wind speed Va respectively.

[0084] When V1>Va, the air supply mechanism 100 in the air supply device is controlled to move to the right; when V1<Va, the air supply mechanism 100 in the air supply device is controlled to move to the left; when V1=Va, the air supply mechanism 100 in the air supply device is controlled not to move;

[0085] When V2>Va, the air supply mechanism 100 in the air supply device is controlled to move upward; when V2<Va, the air supply mechanism 100 in the air supply device is controlled to move downward; when V2=Va, the air supply mechanism 100 in the air supply device is controlled not to move.

[0086] In a specific implementation, in step S2, the preset wind speed Va is obtained by taking a plurality of evenly distributed measuring points on the windward side of the evaporator and coupling the wind speeds of the measuring points, specifically:

[0087] Va=ξ1Va1+ξ2Va2+ξ3Va3, Va1=((V 11 +V 13 / 2+V 12 )) / 2, Va2=((V 21 +V 23 ) / 2+V 22 ) / 2, Va3=((V 31 +V 33 ) / 2+V 32 ) / 2, where ξ1, ξ2, ξ3 are coupling factors, V 11 、V 13 、V 12 、V 21 、V 23 、V 22 、V 31 、V 33 、V 32 are the wind speeds at each measuring point.

[0088] In this embodiment, the measuring points are arranged at the bottom, the middle, the left side, the middle, and the right side of the bottom on the windward side of the evaporator, that is, 9 points: the left side of the bottom, the middle side of the bottom, the right side of the bottom, the left side of the middle, the middle side of the middle, the right side of the middle, the left side of the top, the middle side of the top, and the right side of the top. In other embodiments, the measuring points can also be taken at other positions on the windward side of the evaporator.

[0089] Please refer to Figure 1 The air conditioner in one embodiment includes the above-mentioned air supply device. Through this arrangement, the position of the air supply device can be changed, thereby adjusting the wind field position; the wind field position can be flexibly adjusted according to demand, and the air supply is more uniform during the diversion air supply, which is conducive to improving the heat exchange efficiency of the place to be heat exchanged.

[0090] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
