[0037] See also Figure 1-4The embodiment of the present invention provides an air supply device 2, which is applied to an air conditioner 1. The air conditioner 1 has an air outlet 11 and an air guide plate 12 arranged at the air outlet 11. The air supply device 2 is arranged at the position corresponding to the air outlet 11. The air supply device 2 includes a device body 21, an air supply component 22 and a wind shield 23. The device body 21 is rotatably connected to the air outlet 11, the air supply component 22 is rotatably connected to the device body 21 and / or the wind shield 23 and is used to send air near the device body 21 outward, the wind shield 23 is connected to the device body 21, and the device body 21 is used to realize vector air supply when the wind shield 23 is rotated to face the air outlet direction of the air outlet 11, and realize compound air supply when the wind shield 23 is rotated to face the air outlet direction of the air outlet 11.

[0038] In this embodiment, the air guide plate 12 is used to control the air outlet direction of the air outlet 11. The position of the air supply device 2 corresponding to the air outlet 11 is set to receive the air blown out of the air outlet 11. The air blown out of the air outlet 11 is accelerated by the air supply component 22 to realize vector air supply or the wind from the air outlet 11 is mixed with the indoor air to realize compound air supply, wherein, vector air supply refers to: a direction-controllable air supply mode, that is, directional air supply in a certain direction; compound air supply can also be called compound soft air, which means: after the indoor normal temperature air is fully mixed with the air-conditioning cold air, the hardness of the air-conditioning cold air is reduced and then it is sent into the indoor working area together, that is, the air conditioner 1 can realize at least two air supply modes, namely: vector air supply mode and compound air supply mode.

[0039] In a specific implementation, the air supply device 2 is disposed at the bottom of the air outlet 11 , and the device body 21 rotates up and down relative to the air outlet 11 to achieve that the wind shield plate 23 and the air outlet direction of the air outlet 11 are opposite or facing each other.

[0040] In vector air supply mode, combined with Figure 5-7 As shown, the air conditioner 1 intelligently identifies indoor personnel and heat source areas with high heat dissipation, and controls the rotation angle of the device body 21 relative to the air conditioner 1 so that the wind shield 23 tilts downward toward the position of the air outlet 11, and one end of the air guide plate 12 rotates to a position opposite to the air outlet 11, so that the air blown out of the air outlet 11 is guided to the air supply device 2, and the air supply component 22 rotates the air supply outlet to a suitable angle according to the position of the heat source, thereby realizing precise positioning of air supply. At the same time, the air supply component 22 accelerates the air blown out of the air outlet 11, so that the air blown out of the air outlet 11 is delivered to the ground (i.e., delivered to the ground), which is convenient for quickly meeting the thermal comfort of the user's main working area and reducing the waste of cooling capacity in unmanned areas.

[0041] In the composite soft wind mode, combined with Figure 8-9As shown, the rotation angle of the air conditioner 1 control device body 21 relative to the air conditioner 1 makes the wind shield 23 tilt upward away from the air outlet 11, and the two ends of the air guide plate 12 rotate to the position facing the air outlet 11, so that the air blown out of the air outlet 11 (i.e., the air conditioning cold air, Figure 8 and Fig. 9 The solid arrow in the figure) is guided into the room. At this time, the device body 21, under the action of the air supply component 22, converts the indoor air (indoor normal temperature air, Figure 8 and Fig. 9 The air is sent to the air outlet path of the air outlet 11 by the dotted arrow in the figure, that is, the air supply direction of the air supply component 22 is the same as the air outlet direction of the air outlet 11 (that is, in opposite directions), so that the indoor normal temperature air and the air-conditioned cold air are fully mixed, thereby reducing the hardness of the air-conditioned cold air and improving the user's comfort.

[0042] It should be noted that for the air supply component 22, in the vector air supply mode, the air near the device body 21 is the wind blown out of the air outlet 11, and in the composite soft wind mode, the air near the device body 21 is the indoor air (or indoor wind). In this embodiment, by rotating the device body 21, the air conditioner 1 can achieve at least two air supply modes. In the vector air supply mode, the air supply device 2 can achieve targeted air supply to the user's work area under high temperature conditions and quickly meet the local thermal comfort of the user's work area; in the composite air supply mode, the air supply device 2 can reduce the hardness of the air-conditioning cold air to ensure air supply comfort.

[0043] Specifically, the rotation center of the device body 21 is perpendicular to the rotation center of the air supply assembly 22 .

[0044] In this embodiment, the device body 21 needs to receive the wind blown out by the air outlet 11, and the device body 21 is arranged at the bottom of the air outlet 11, therefore, the device body 21 needs to rotate according to the air outlet direction of the air outlet 11, that is, the device body 21 needs to rotate up and down relative to the air outlet 11, so as to realize that the wind shield 23 is opposite or facing the air outlet direction of the air outlet 11; the air supply component 22 is used to send the air near the device body 21 outward and send it to the heat source position, therefore, the air supply component 22 needs to rotate left and right according to the heat source position to realize targeted air supply. In summary, the device body 21 rotates up and down, and the air supply component 22 rotates left and right. Through two different rotation methods, precise positioning of air supply at different positions in the room can be realized.

[0045] Specifically, the rotation center of the device body 21 is parallel to the rotation center of the air guide plate 12 .

[0046] In this embodiment, the air guide plate 12 is arranged at the air outlet 11, and can rotate up and down relative to the air outlet 11 to control the air outlet direction of the air outlet 11. The device body 21 rotates up and down relative to the air outlet 11 according to the air outlet direction of the air outlet 11, that is, the device body 21 and the air guide plate 12 both rotate up and down relative to the air outlet 11, and the two cooperate to realize that the wind shield plate 23 is opposite to or facing the air outlet direction of the air outlet 11, thereby realizing two air supply modes.

[0047] Specifically, the air supply assembly 22 uses the plane of the wind shield plate 23 as a rotation plane.

[0048] In this embodiment, the air supply component 22 is rotatably connected to the wind shield 23, and can be rotated on the wind shield 23 to achieve left and right swinging, so that the air supply port of the air supply component 22 faces the heat source position to achieve targeted air supply.

[0049] Specifically, Figure 4 As shown, the device body 21 includes a first driving member, a gear 211 connected to the first driving member, and an arc-shaped rack 212 meshing with the gear 211. The windshield 23 is connected to the arc-shaped rack 212. The first driving member can drive the gear 211 to rotate to drive the arc-shaped rack 212 to rotate.

[0050] In this embodiment, the device body 21 is rotated by a gear 211 and an arc-shaped rack 212. Specifically, the gear 211 is installed on the outside of the air conditioner 1 at a position corresponding to the air outlet 11, and the arc-shaped rack 212 is meshed and connected with the gear 211. Both ends of the arc-shaped rack 212 are fixedly connected to the wind shield 23. The first driving member drives the gear 211 to rotate, thereby driving the arc-shaped rack 212 to rotate in the same direction, so that the wind shield 23 is tilted toward or away from the air outlet 11, thereby realizing that the wind shield 23 and the air outlet direction of the air outlet 11 are opposite or facing each other. During specific implementation, when the first driving member drives the gear 211 to rotate clockwise by N1 (N1=5°*n, 0<n≤12, n is an integer), the arc-shaped rack 212 is driven to rotate clockwise around the gear 211. Since the arc-shaped rack 212 is fixedly connected to the wind shield 23, when the arc-shaped rack 212 rotates clockwise, it will drive the wind shield 23 to tilt downward, and the air supply component 22 is arranged on the wind shield 23, so that the entire air supply device 2 supplies air downward; when the first driving member drives the gear 211 to rotate counterclockwise by N2 (N2=5°*n, 0<n≤5, n is an integer), the arc-shaped rack 212 is driven to rotate counterclockwise around the gear 211. Since the arc-shaped rack 212 is fixedly connected to the wind shield 23, when the arc-shaped rack 212 rotates counterclockwise, it will drive the wind shield 23 to tilt upward, and the air supply component 22 is arranged on the wind shield 23, so that the entire air supply device 2 supplies air upward. In this embodiment, the gear 211 and the arc-shaped rack 212 are used to control the up and down rotation of the device body 21, so that the air conditioner 1 can be turned on and switched between the two air supply modes.

[0051] Specifically, Figure 2 and Figure 3 As shown, the air supply assembly 22 includes multiple air supply parts 221, the device body 21 includes a second driving part, a driving wheel 213 connected to the second driving part, at least one driven wheel 214 and a transmission belt 215 sleeved between the driving wheel 213 and at least one driven wheel 214, the driving wheel 213 is connected to one of the air supply parts 221, and at least one driven wheel 214 is respectively connected to the remaining air supply parts 221.

[0052] In this embodiment, in order to meet the user's air volume requirements, the air supply assembly 22 includes a plurality of air supply parts 221, and the plurality of air supply parts 221 are connected to the wind shield 23 through a driving wheel 213 and a driven wheel 214. Specifically, one of the air supply parts 221 is connected to the driving wheel 213, and the driven wheel 214 is connected to the remaining air supply parts 221. The driving wheel 213 and the driven wheel 214 are connected through a transmission belt 215. A second driving part that can drive the driving wheel 213 to rotate is installed on the driving wheel 213. When the driving wheel 213 rotates, the remaining driven wheels 214 are driven to rotate in the same direction under the action of the transmission belt 215, thereby realizing the left and right rotation of the plurality of air supply parts 221. In a specific implementation, when the second driving member drives the driving wheel 213 to rotate rightward by N3 (N3 can be 0-90°), the driven wheel 214 is driven to rotate rightward, so that all the air supply members 221 can swing to the right. Similarly, when the driving wheel 213 rotates leftward by N4 (N4 can be -90-0°, where 90° of N3 and -90° of N4 represent different rotation directions, i.e., rightward rotation is positive and leftward rotation is negative), all the air supply members 221 can swing to the left. In addition, if only one air supply member 221 is provided, the air supply member 221 only needs to be connected to the driving wheel 213, and the driving wheel 213 can be controlled to rotate left and right by the second driving member, without the need for the driven wheel 214 and the transmission belt 215. Among them, the air supply member 221 can be a centrifugal fan.

[0053] like Figure 1 As shown, an embodiment of the present invention further provides an air conditioner 1 having an air outlet 11 and an air guide plate 12 arranged at the air outlet 11 , and also comprising the air supply device 2 as described above arranged at a position corresponding to the air outlet 11 .

[0054] In this embodiment, the air conditioner 1 controls the air outlet direction of the air outlet 11 through the air guide plate 12 to send the air blown out of the air outlet 11 to the air supply device 2, and the air supply device 2 can realize multi-angle vector air supply and compound air supply indoors.

[0055] The embodiment of the present invention further provides a control method for an air conditioner, which is applied to the air conditioner 1 as described above, and comprises:

[0056] When receiving the vector air supply instruction, the control device body 21 rotates until the wind shield 23 is opposite to the air outlet direction of the air outlet 11;

[0057] When receiving the combined air supply instruction, the control device body 21 rotates until the wind shield plate 23 faces the air outlet direction of the air outlet 11 .

[0058] In this step, the air conditioner 1 includes a vector air supply mode and a compound air supply mode. When a vector air supply instruction is received, air needs to be supplied to the heat source position (heat source area) in a directional manner. The first driving member drives the gear 211 to rotate clockwise to drive the arc-shaped rack 212 to rotate clockwise, thereby driving the device body 21 to rotate, and the wind shield 23 is tilted downward relative to the position of the air outlet 11. One end of the air guide plate 12 is rotated to a position opposite to the air outlet 11, so that the air outlet direction of the air outlet 11 is opposite to the wind shield 23, and the second driving member drives the active wheel 213 to rotate left and right according to the heat source position to drive the air supply component 22 to swing left and right, so that the air blown out of the air outlet 11 is quickly delivered to the heat source area, and the air blown out of the air outlet 11 is accelerated by the air supply component 22, and the air supply speed is increased, which can ensure that the air is delivered to the ground, solving the problem of air leakage. The invention solves the problems of limited air supply range of conventional air conditioners and air supply not falling to the ground; when a composite air supply instruction is received, the hardness of the air conditioner cold air needs to be reduced. At this time, the first driving member drives the gear 211 to rotate counterclockwise to drive the arc-shaped rack 212 to rotate counterclockwise, thereby driving the device body 21 to rotate, and the wind shield 23 is tilted upward relative to the position of the air outlet 11. The two ends of the air guide plate 12 rotate to a position facing the direction of the air outlet 11, so that the air outlet direction of the air outlet 11 is guided to the room. At this time, the air supply component 22 delivers the indoor normal temperature air to the air outlet path of the air outlet 11, so that the indoor normal temperature air and the air conditioner cold air are fully mixed, and the air supply hardness is reduced. The second driving member drives the active wheel 213 to rotate left and right according to the heat source position to drive the air supply component 22 to swing left and right, so that the mixed air is quickly delivered to the heat source position. This embodiment can receive instructions for different air supply modes and control the rotation of the device body 21 to realize intelligent switching of multiple air supply modes.

[0059] Specifically, when a vector air supply instruction is received, the control device body 21 rotates until the wind shield 23 is opposite to the air outlet direction of the air outlet 11, including: obtaining the position of the heat source area, and rotating the device body 21 and / or the air supply component 22 according to the position so that the air supply direction of the air supply component 22 is toward the heat source area.

[0060] In this step, after the air conditioner 1 is turned on, the infrared heat energy monitor monitors the data and determines whether there are large heat source areas such as personnel and heat dissipation equipment in the room. If there is no heat source area, there is no need to control the rotation of the device body 21. The air conditioner runs in the conventional air supply mode, and the temperature of the whole house is gradually controlled by the diffusion effect of the cold air (such as Fig.10 and Fig.11If there is a heat source area, the position of the heat source area is obtained, and the vector air supply mode is turned on. The rotation angle (N1) of the gear 211 is determined according to the position of the heat source area to control the rotation of the device body 21 and / or the rotation angle (N3 or N4) of the driving wheel 213 to control the rotation of the air supply component 22. The heat source area will be divided into multiple partitions, and the rotation angles of the gear 211 and the driving wheel 213 corresponding to each partition are formed by a large amount of experimental data and simulation data to form a corresponding matching database. At this time, the air conditioner controls the rotation of the gear 211 and the driving wheel 213 according to the matching value of the database, so that the air conditioning cold air can be directly and directionally sent to the heat source area, quickly realizing the temperature control and thermal comfort requirements of the main working area of ​​the heat source, and avoiding the waste of cooling capacity in the unmanned area.

[0061] Specifically, when a composite air supply instruction is received, the control device body 21 rotates until the wind shield 23 is opposite to the air outlet direction of the air outlet 11, including: obtaining the temperature of the heat source area, and rotating the device body 21 and / or the air supply component 22 according to the temperature so that the air supply direction of the air supply component 22 is opposite to the air outlet direction of the air outlet 11.

[0062] In this step, after the air conditioner is turned on, the target temperature T is pre-set, and the temperature T1 of the heat source area is monitored. When it is monitored that T1≤T+5℃, the compound air supply mode is turned on, and the rotation angle (N2) of the gear 211 is determined according to the position and temperature of the heat source area to control the rotation of the device body 21 and / or the rotation angle (N3 or N4) of the driving wheel 213 to control the rotation of the air supply component 22, so that the air-conditioned cold air and the indoor normal temperature air are fully mixed and then supplied to the room, thereby reducing the hardness of the air-conditioned cold air and avoiding the discomfort caused by the user during the blowing process at a lower temperature.

[0063] This embodiment can control the operation of two air supply modes separately, or can organically combine the two air supply modes. For example, after obtaining the position of the heat source area, the device body 21 and / or the air supply component 22 are rotated according to the position control so that the air supply direction of the air supply component 22 is toward the heat source area, thereby realizing the vector air supply mode. While running the vector air supply mode, the temperature T1 of the heat source area is monitored. When it is monitored that T1≤T+5℃, the device body 21 and / or the air supply component 22 are rotated so that the air supply direction of the air supply component 22 is opposite to the air outlet direction of the air outlet 11, thereby realizing the composite air supply mode; when it is monitored that T1>T+5℃, the vector air supply mode is switched. That is, after monitoring the heat source, the vector air supply mode is first realized according to the position of the heat source area to reduce its temperature as soon as possible, and then the composite air supply mode is realized according to the change in temperature to reduce the hardness of the cold air of the air conditioner, and the switching of the air supply mode is realized according to the change in temperature.

[0064] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
