Detailed implementation manners

[0057] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0058] The embodiment of the present application provides an air conditioner, as Figures 1-6As shown in the figure, the air conditioner includes an air conditioner main body 100 and a humidifying mechanism 200. An air outlet 101 is provided on the air conditioner main body 100, and the humidifying mechanism 200 is arranged at the air outlet 101. The humidifying mechanism 200 includes a blade assembly and a water tank 220. The water tank 220 is arranged on the air conditioner main body 100 and extends along the length direction of the air outlet 101. A water inlet pipe 310 and a water outlet pipe 320 are connected to the water tank 220. The blade assembly includes a plurality of blades 211 and a driving member 212. The plurality of blades 211 are rotatably arranged on the water tank 220 and arranged along the length direction of the air outlet 101. The blade 211 is provided with a receiving cavity and a plurality of through holes 2111 communicating with the receiving cavity. The receiving cavity is filled with a breathable water-absorbing body 213, and a part of the water-absorbing body 213 passes through the receiving cavity and extends into the water tank 220. The driving member 212 can drive the plurality of blades 211 to rotate simultaneously to adjust the windward area of the blades 211. Among them, when the blade 211 rotates, it rotates around an axis parallel to the height direction of the air conditioner main body 100.

[0059] Among them, the water level of the water tank 220 determines the water absorption amount of the water-absorbing body 213. The water absorption amount of the water-absorbing body 213 and the windward area of the blade 211 can jointly control the amount of water vapor carried by the air blown out of the air conditioner, thereby adjusting the indoor environmental humidity. The through holes 2111 on the blade 211 provide a passage for the air blown out of the air conditioner to pass through the water-absorbing body 213. When the rotation angle of the blade 211 is 0° (as Figure 2 shown) or 180°, the windward area of the blade 211 is the largest; when the rotation angle of the blade 211 is 90°, the windward area of the blade 211 is the smallest.

[0060] In the air conditioner provided by the embodiment of the present application, a humidifying mechanism 200 is arranged at the air outlet 101 of the air conditioner main body 100. The humidifying mechanism 200 absorbs the water in the water tank 220 through the water-absorbing body 213 on the blade 211. By adjusting the rotation angle of the blade 211, the windward area of the blade 211 can be adjusted. When the air blown out from the air outlet 101 of the air conditioner main body 100 passes through the blade 211, the water-absorbing body 213 after absorbing water can humidify the air blown out of the air conditioner, thereby effectively adjusting the indoor environmental humidity, greatly improving the problem that the existing air conditioner cannot humidify or the humidifying effect is not obvious, and improving the human body comfort.

[0061] Optionally, the water-absorbing body 213 can be a sponge or other materials that can absorb water and be breathable. Specifically, as Figure 4 and Figure 5As shown, the water absorption body 213 includes a first water absorption part 2131 and a second water absorption part 2132. The first water absorption part 2131 and the second water absorption part 2132 are of an integrally formed structure. Among them, the first water absorption part 2131 is filled in the accommodation cavity of the blade 211, and the second water absorption part 2132 extends into the water tank 220 to absorb the water in the water tank 220 and transport the water to the first water absorption part 2131 for the first water absorption part 2131 to absorb. When the wind blown out by the air conditioner main body 100 passes through the blade 211, the first water absorption part 2131 after absorbing water can humidify the air blown out by the air conditioner, thereby effectively adjusting the indoor environmental humidity.

[0062] In some embodiments of the present application, as Figure 2 and Figure 3 shown, the blade assembly further includes a connecting rod 214. The connecting rod 214 is movably arranged on the water tank 220, and a plurality of blades 211 are connected to the connecting rod 214. The driving member 212 can drive the connecting rod 214 to reciprocate along the length direction of the air outlet 101, so that a plurality of blades 211 rotate simultaneously, thereby adjusting the wind receiving area of the blades 211. It can be understood that the arrangement of the connecting rod 214 can realize driving a plurality of blades 211 to rotate simultaneously by one driving member 212, thereby reducing the number of driving members 212 and lowering the equipment cost. Optionally, the driving member 212 can be a motor or other devices capable of driving the blades 211 to rotate.

[0063] Optionally, as Figure 2 and Figure 3 shown, the blade assembly further includes a support 215. The support 215 covers the notch of the water tank 220. A rotating shaft 216 is arranged at the bottom of the blade 211. The rotating shaft 216 is rotatably arranged through the support 215 and connected to the connecting rod 214. The driving member 212 can drive the connecting rod 214 to reciprocate along the length direction of the air outlet 101, so that the rotating shaft 216 drives the blade 211 to rotate around the center line of the rotating shaft 216. The center line of the rotating shaft 216 is parallel to the height direction of the air conditioner main body 100. Through the cooperation of the connecting rod 214, the rotating shaft 216 and the support 215, a plurality of blades 211 are driven by the driving member 212 to rotate simultaneously on the support 215 to adjust the wind receiving area of the blades 211.

[0064] Among them, the blade 211 and the rotating shaft 216 can be of an integrally formed structure, which is convenient for production. After the support 215 covers the notch of the water tank 220, it can also be detachably connected to the water tank 220 by a buckle or a screw.

[0065] Optionally, a plurality of clamping holes 2141 corresponding to the plurality of blades 211 are formed in the connecting rod 214, and a clamping buckle 217 is arranged on the rotating shaft 216. The clamping buckle 217 is clamped into the corresponding clamping hole 2141, that is, the clamping buckle 217 on the rotating shaft 216 of each blade 211 is clamped into the corresponding clamping hole 2141. By providing the clamping holes 2141 and the clamping buckles 217 with the above structures, the detachable connection between the blade 211 and the connecting rod 214 can be realized, thereby facilitating the disassembly, assembly and replacement of the blade 211. Among them, the blade 211, the rotating shaft 216 and the clamping buckle 217 can be integrally formed structures, which is convenient for production.

[0066] Optionally, as Figure 4 shown, the blade 211 may include two sub-blades 2112, and a plurality of through holes 2111 are arranged on each sub-blade 2112. The two sub-blades 2112 are detachably connected and enclose a receiving cavity; the rotating shaft 216 includes two sub-rotating shafts, and the two sub-rotating shafts are correspondingly arranged at the bottoms of the two sub-blades 2112, and the two sub-rotating shafts enclose a channel communicating with the receiving cavity. A part of the water absorbing body 213 (that is, the second water absorbing part 2132 of the water absorbing body 213) passes through the receiving cavity and then passes through the channel and extends into the water tank 220. By providing the blade 211 with the two sub-blades 2112 having the above structures and providing the rotating shaft 216 with the two sub-rotating shafts having the above structures, the water absorbing body 213 can be detachably assembled in the blade 211, thereby facilitating the disassembly, assembly and replacement of the water absorbing body 213.

[0067] Optionally, the two sub-blades 2112 can be detachably connected by a snap connection method or a screw connection method; each sub-blade 2112 and the sub-rotating shaft arranged on the sub-blade 2112 can be integrally formed structures, which is convenient for production.

[0068] Optionally, the water inlet pipe 310 and the water outlet pipe 320 can be arranged on the same side or different sides of the water tank 220. The present application does not limit this, as long as the function that the water tank 220 can be filled with water through the water inlet pipe 310 and drained through the drain pipe can be realized. Exemplarily, as Figure 6 shown, the water inlet pipe 310 and the water outlet pipe 320 are respectively arranged on the left and right sides of the water tank 220.

[0069] Optionally, as Figure 1As shown in the figure, the air conditioner provided by the embodiment of the present application further includes a water tank 400, a humidity detector 500 and a water level detector. The water tank 400 is arranged on the air conditioner main body 100. The water tank 400 is communicated with the water tank 220 through a water inlet pipe 310. An inlet valve for controlling the water inflow is arranged on the water inlet pipe 310, and an outlet valve for controlling the water outflow is arranged on the water outlet pipe 320. The humidity detector 500 is arranged on the outer surface of the air conditioner main body 100 (for example, it can be arranged at the top of the outer surface of the air conditioner body). The water level detector is arranged on the wall of the water tank 220. The water level detector, the inlet valve, the outlet valve and the driving member 212 are all communicatively connected with the humidity detector 500, so that the air conditioner can adjust the indoor environmental humidity.

[0070] Specifically, the water tank 400 can add water into the water tank 220 through the water inlet pipe 310 for use when the air conditioner adjusts the indoor environmental humidity. In addition, a drainage structure is arranged between the evaporator of the air conditioner body and the water tank 220, so that the condensed water generated during the heat exchange of the evaporator can be introduced into the water tank 220 through the drainage structure for use when the air conditioner adjusts the indoor environmental humidity.

[0071] The embodiment of the present application also provides a humidity adjustment control method for an air conditioner, and this humidity adjustment control method can be applied to the air conditioner provided by the present application. As Figure 7 shown, the humidity adjustment control method of the air conditioner includes the following steps:

[0072] S100. When the air conditioner is operating in the cooling mode, heating mode, air supply mode or fresh air mode, a humidification instruction is received.

[0073] S200. Detect the indoor environmental humidity. Specifically, after the air conditioner operating in the cooling mode, heating mode, air supply mode or fresh air mode receives the humidification instruction, the indoor environmental humidity is detected through the humidity detector 500.

[0074] S300. Adjust the indoor environmental humidity by controlling at least one of the water level of the water tank 220, the windward area of the blade 211 and the rotation speed of the air outlet fan of the air conditioner main body 100 until the indoor environmental humidity reaches the target humidity corresponding to the humidification instruction. Among them, controlling the windward area of the blade 211 is achieved by adjusting the rotation angle of the blade 211. When the rotation angle of the blade 211 is 0° or 180°, the windward area of the blade 211 is the largest; when the rotation angle of the blade 211 is 90°, the windward area of the blade 211 is the smallest.

[0075] The humidity adjustment control method of the air conditioner provided by the embodiment of the present application adjusts the indoor environmental humidity by controlling at least one of the water level of the water tank 220, the windward area of the blade 211, and the rotation speed of the air outlet fan, so that the indoor environmental humidity reaches the target humidity corresponding to the humidification instruction, thereby effectively adjusting the indoor environmental humidity, greatly improving the problem that the existing air conditioner cannot humidify or the humidification effect is not obvious, and improving the human body comfort.

[0076] Optionally, in step S300, controlling the water level of the water tank 220 includes: in the cooling mode, controlling the condensed water entering the water tank 220 and the water discharged from the water tank 400 to control the water level of the water tank 220; in the heating mode, the air supply mode or the fresh air mode, controlling the water discharged from the water tank 400 entering the water tank 220 to control the water level of the water tank 220. Among them, the condensed water refers to the condensed water generated by the heat exchange of the evaporator during air conditioner refrigeration, and the water discharged from the water tank 400 refers to the water flowing from the water tank 400 into the water tank 220.

[0077] As Figure 8 shown, in some embodiments of the present application, adjusting the indoor environmental humidity by controlling at least one of the water level of the water tank 220, the windward area of the blade 211, and the rotation speed of the air outlet fan of the air conditioner main body 100 includes the following steps:

[0078] S310. In the cooling mode, control the condensed water on the evaporator of the air conditioner body to be introduced into the water tank 220, and control the blade 211 to rotate to a preset angle α, 0° < α < 180°. Among them, by controlling the blade 211 to rotate to the preset angle, the initial windward area of the blade 211 can be controlled to be the preset windward area.

[0079] S320. Detect the water level of the water tank 220, specifically, the water level of the water tank 220 can be detected by a water level detector.

[0080] S331. When the water level of the water tank 220 is M, if the indoor environmental humidity is equal to the target humidity, keep the water level of the water tank 220 at M, control the water outlet valve to open to discharge the excess condensed water (that is, the excess condensed water in the water tank 400) through the water outlet pipe 320, M < H, and H is the highest water level of the water tank 220.

[0081] S332. When the water level of the water tank 220 is M, if the indoor environmental humidity is less than the target humidity, make the water tank 220 continue to accumulate condensed water (that is, control the water level of the water tank 220 to continue to increase) until the indoor environmental humidity is equal to the target humidity. It should be noted that at this time, the water inlet valve on the water inlet pipe 310 and the water outlet valve on the water outlet pipe 320 are both in the closed state. It can be understood that by continuously increasing the water level of the water tank 220, the humidification intensity of the air conditioner can be increased, so that the indoor environmental humidity approaches the target humidity.

[0082] S333. When the water level in the water tank 220 is N, where N is the highest water level that the condensed water can reach in the water tank 220, and M < N < H, if the indoor environmental humidity is less than the target humidity, control the blade 211 to rotate to increase the windward area of the blade 211 until the indoor environmental humidity is equal to the target humidity. It can be understood that by increasing the windward area of the blade 211, the humidification intensity of the air conditioner can be increased to make the indoor environmental humidity approach the target humidity. Specifically, the rotation angle of the blade 211 can be adjusted step by step based on the current rotation angle to gradually increase the windward area of the blade 211, thereby increasing the indoor environmental humidity.

[0083] Optionally, the humidity adjustment control method of the air conditioner further includes the following steps: S334. When the water level in the water tank 220 is N (i.e., the condensed water in the water tank 220 has accumulated to the highest water level N that the condensed water can reach) and the windward area of the blade 211 is the largest, if the indoor environmental humidity is less than the target humidity, control the water inlet valve to open so that the water in the water tank 400 flows into the water tank 220 through the water inlet pipe 310 until the indoor environmental humidity is equal to the target humidity. It can be understood that when the water level in the water tank 220 is N and the windward area of the blade 211 is the largest, by controlling the water in the water tank 400 to flow into the water tank 220 through the water inlet pipe 310, the water level in the water tank 220 can be continuously increased, thereby increasing the humidification intensity of the air conditioner to make the indoor environmental humidity approach the target humidity.

[0084] Further, after the step of controlling the water inlet valve to open, the humidity adjustment control method of the air conditioner further includes the following steps: S335. When the water level in the water tank 220 is H (i.e., the water level in the water tank 220 reaches the maximum value), if the indoor environmental humidity is less than the target humidity, increase the rotation speed of the air outlet fan of the air conditioner main body 100 until the indoor environmental humidity is equal to the target humidity. It can be understood that when the water level in the water tank 220 is H and the windward area of the blade 211 is the largest, by increasing the rotation speed of the air outlet fan, the air flow rate can be increased, thereby continuously increasing the humidification intensity of the air conditioner to make the indoor environmental humidity approach the target humidity. Specifically, the rotation speed of the air outlet fan can be increased step by step based on the current rotation speed to achieve the purpose of gradually increasing the air flow rate, thereby increasing the indoor environmental humidity.

[0085] As Figure 9 shown, in some other embodiments of the present application, the method for adjusting the indoor environmental humidity by controlling at least one of the water level in the water tank 220, the windward area of the blade 211, and the rotation speed of the air outlet fan of the air conditioner main body 100 includes the following steps:

[0086] S340. In the heating mode, air supply mode or fresh air mode, control the blade 211 to rotate to a preset angle α, where 0° < α < 180°, and control the water inlet valve to open so that the water in the water tank 400 flows into the water trough 220 through the water inlet pipe 310. Among them, by controlling the blade 211 to rotate to the preset angle, the initial windward area of the blade 211 can be controlled to be the preset windward area. It can be understood that since no condensed water enters the water trough 220 in the heating mode, air supply mode or fresh air mode, the water tank 400 is directly used to fill the water trough 220.

[0087] S350. Detect the water level of the water trough 220, specifically by using a water level detector to detect the water level of the water trough 220.

[0088] S361. When the water level of the water trough 220 is M, if the indoor environmental humidity is equal to the target humidity, keep the water level of the water trough 220 at M, control the water outlet valve to open to drain the excess water through the water outlet pipe 320, where M < H, and H is the maximum water level of the water trough 220;

[0089] S362. When the water level of the water trough 220 is M, if the indoor environmental humidity is less than the target humidity, control the water tank 400 to continue filling the water trough 220 (that is, control the water level of the water trough 220 to continue to increase) until the indoor environmental humidity is equal to the target humidity. It should be noted that at this time, both the water inlet valve on the water inlet pipe 310 and the water outlet valve on the water outlet pipe 320 are in the closed state. It can be understood that by continuously increasing the water level of the water trough 220, the humidification intensity of the air conditioner can be increased so that the indoor environmental humidity approaches the target humidity.

[0090] S363. When the water level of the water trough 220 is H (that is, the water level of the water trough 220 reaches the maximum value), if the indoor environmental humidity is less than the target humidity, control the blade 211 to rotate to increase the windward area of the blade 211 until the indoor environmental humidity is equal to the target humidity. It can be understood that by increasing the windward area of the blade 211, the humidification intensity of the air conditioner can be increased so that the indoor environmental humidity approaches the target humidity. Specifically, the blade 211 can be controlled to gradually adjust the rotation angle on the basis of the current rotation angle to gradually increase the windward area of the blade 211, thereby increasing the indoor environmental humidity.

[0091] Optionally, the humidity adjustment control method of the air conditioner further includes the following steps: S364. When the water level in the water tank 220 is H and the windward area of the blade 211 is the largest, if the indoor environmental humidity is less than the target humidity, increase the rotation speed of the air outlet fan of the air conditioner main body 100 until the indoor environmental humidity is equal to the target humidity. It can be understood that, when the water level in the water tank 220 is H and the windward area of the blade 211 is the largest, by increasing the rotation speed of the air outlet fan, the air flow rate can be increased, thereby further increasing the humidification intensity of the air conditioner to make the indoor environmental humidity approach the target humidity. Specifically, the air outlet fan can be controlled to increase the rotation speed step by step based on the current rotation speed to achieve the purpose of gradually increasing the air flow rate, and then increase the indoor environmental humidity.

[0092] An embodiment of the present application also provides a humidity adjustment control method for an air conditioner, and this humidity adjustment control method can be applied to the air conditioner provided by the present application. As Figure 10 shown, the humidity adjustment control method of the air conditioner includes the following steps:

[0093] S101. When the air conditioner is operating in the cooling mode, receive a humidification instruction and a swing instruction;

[0094] S102. Control the blade 211 to rotate back and forth for swing, and control the condensed water on the evaporator of the air conditioner main body to be introduced into the water tank 220.

[0095] S103. Detect the water level in the water tank 220 and the indoor environmental humidity. Specifically, after the air conditioner operating in the cooling mode receives the humidification instruction and the swing instruction, the water level in the water tank 220 is detected by a water level detector, and the indoor environmental humidity is detected by a humidity detector 500.

[0096] S104. When the water level in the water tank 220 is M, if the indoor environmental humidity is equal to the target humidity corresponding to the humidification instruction, keep the water level in the water tank 220 at M, control the water outlet valve to open to discharge the excess condensed water through the water outlet pipe 320, where M < H, and H is the highest water level of the water tank 220.

[0097] S105. When the water level in the water tank 220 is M, if the indoor environmental humidity is less than the target humidity, control the evaporator water tank 220 of the air conditioner main body to continue accumulating condensed water until the indoor environmental humidity is equal to the target humidity. It should be noted that at this time, the water inlet valve on the water inlet pipe 310 and the water outlet valve on the water outlet pipe 320 are both in the closed state. It can be understood that by continuing to accumulate condensed water to increase the water level in the water tank 220, the humidification intensity of the air conditioner can be increased to make the indoor environmental humidity approach the target humidity.

[0098] S106. When the water level in the water tank 220 is N, where N is the highest water level that the condensed water can reach in the water tank 220, and M < N < H, if the indoor environmental humidity is less than the target humidity, control the water inlet valve to open so that the water in the water tank 400 flows into the water tank 220 through the water inlet pipe 310 until the indoor environmental humidity is equal to the target humidity. It can be understood that when the water level in the water tank 220 is N, by controlling the water in the water tank 400 to flow into the water tank 220 through the water inlet pipe 310, the water level in the water tank 220 can be continuously increased, thereby increasing the humidification intensity of the air conditioner so that the indoor environmental humidity approaches the target humidity.

[0099] Optionally, the humidity adjustment control method of the air conditioner further includes the following steps: S107. When the water level in the water tank 220 is H, if the indoor environmental humidity is less than the target humidity, increase the rotation speed of the air outlet fan of the air conditioner main body 100 until the indoor environmental humidity is equal to the target humidity. It can be understood that when the water level in the water tank 220 is H, by increasing the rotation speed of the air outlet fan, the air flow rate can be increased, thereby continuously increasing the humidification intensity of the air conditioner so that the indoor environmental humidity approaches the target humidity. Specifically, the rotation speed of the air outlet fan can be controlled to increase step by step based on the current rotation speed to achieve the purpose of gradually increasing the air flow rate, thereby increasing the indoor environmental humidity.
