The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

As shown in fig. 1 to 4, an air conditioner 1 according to an embodiment of the present invention includes an air conditioning device 10, a fresh air device 20, and an intermediate support 30.

Specifically, as shown in fig. 2 to 4, the air conditioner 10 includes a drain pan 100, and the drain pan 100 includes an overflow hole 111. The condensed water formed on the heat exchanger or the air deflector in the air conditioner 10 may be collected in the drip tray 100. The overflow hole 111 penetrates the drain pan 100, and the condensed water in the drain pan 100 can flow out of the drain pan 100 through the overflow hole 111.

As shown in fig. 1-4, the fresh air device 20 has a humidification module. The humidification module can humidify the air flow in the fresh air device 20 to improve the humidity of the air flow. The fresh air device 20 is located below the air conditioner 10. It should be noted that the reference to "below" is based on the relative positions of the fresh air device 20 and the air conditioning device 10 shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1 to 4, the intermediate support member 30 is connected between the air conditioning device 10 and the fresh air device 20. The intermediate support member 30 has a communication channel 310 therein, and the air inlet end of the air conditioner 10 is communicated with the fresh air device 20 through the communication channel 310. It is understood that the intermediate support member 30 is located between the air conditioner 10 and the fresh air device 20, and the intermediate support member 30 is connected to both the air conditioner 10 and the fresh air device 20. The intermediate support 30 has a communication passage 310 that allows air flow therethrough. The air flow in the fresh air device 20 can pass through the communication channel 310 and enter the air conditioning device 10.

As shown in fig. 4, 5, 8 and 10, the inner peripheral wall of the communication channel 310 has an overflow guide 320, and the overflow hole 111 communicates with the overflow guide 320 to guide the overflow water in the water tray 100 to the humidification module. It is understood that the intermediate support 30 has the overflow drain 320, and the overflow drain 320 is located in the communication passage 310. As shown in fig. 5, the dashed arrows represent the flow path of the condensed water, and the condensed water in the drip tray 100 can flow through the overflow channel 320 via the overflow holes 111, and can flow into the humidification module in the fresh air device 20 under the guidance of the overflow channel 320.

According to the air conditioner 1 of the embodiment of the invention, the overflow hole 111 is arranged on the water pan 100, when the water pan 100 can not drain normally, the condensed water can flow through the intermediate support member 30 from the overflow hole 111 and flows to the humidification module under the guidance of the overflow guide groove 320 in the intermediate support member 30, and the humidification module can humidify the air flow by using the condensed water or further discharge the condensed water out of the air conditioner 1, so that the condensed water can be prevented from flowing into the electric control box 210 or other structural components in the fresh air device 20, the safety performance of the air conditioner 1 can be improved, and the service life of the air conditioner 1 can be prolonged.

In some embodiments of the present invention, the air conditioner 1 may be provided with an alarm device. After the condensed water flows into the humidifying module, the humidifying module can automatically start a humidifying function to evaporate the condensed water into air in a humidifying mode and trigger the alarm device to give an alarm to remind a user to maintain the drainage channel of the water pan 100.

As shown in fig. 11, in some embodiments of the invention, the humidification module may be provided with a bottom plate 40, the bottom plate 40 having a drain hole 400. The condensed water flowing from the overflow drain 320 to the humidifying module may flow into the bottom chassis 40, and the condensed water in the bottom chassis 40 may be directly or indirectly discharged out of the air conditioner 1 through the drain hole 400.

As shown in fig. 6 and 7, according to some embodiments of the present invention, the water tray 100 may have a protrusion 110 therein, and the overflow hole 111 penetrates through the protrusion 110. For example, the inner bottom wall of the water tray 100 may be provided with the protrusion 110, the protrusion 110 may be formed as a cylindrical pillar, and the overflow hole 111 may penetrate the protrusion 110 and the inner bottom wall of the water tray 100 in the axial direction of the protrusion 110. When the level of the condensed water in the drip tray 100 exceeds the end surface of the free section of the protrusion 110, the condensed water may flow into the overflow hole 111. Therefore, the drain hole 111 does not drain water when the drain pan 100 is normally drained, and the drain hole 111 drains water when the drain pan 100 is not normally drained and condensed water is collected in the drain pan 100.

It should be noted that the end face of the free end of the protrusion 110 needs to be located below the lowest position of the side wall of the drip tray 100, so as to ensure that the condensed water in the drip tray 100 is drained from the overflow hole 111 before the condensed water turns over the side wall of the drip tray 100 and overflows from the side wall of the drip tray 100.

According to some embodiments of the present invention, the overflow hole 111 may be provided at a side wall of the drip tray 100. It is understood that the overflow hole 111 may be formed in the side wall of the drain pan 100 and penetrate the side wall of the drain pan 100. For example, the overflow hole 111 may penetrate through a side wall of the drain pan 100 in the axial direction of the drain pan 100, that is, in the depth direction of the drain pan 100. For another example, in a direction from the center to the periphery of the water collector 100, that is, in a thickness direction of the side wall of the water collector 100, the overflow hole 111 may penetrate through the side wall of the water collector 100, and the overflow hole 111 is close to an end of the side wall of the water collector 100, which is far away from the bottom wall of the water collector 100. Therefore, the arrangement of the overflow holes 111 is convenient, the structure of the water collector 100 can be simplified, and the production cost of the water collector 100 is reduced.

As shown in fig. 4 and 5, according to some embodiments of the present invention, the inner bottom wall of the drain pan 100 may be formed as an inclined surface. It will be appreciated that the inner bottom wall of the drip tray 100 may form an angle with the horizontal that is greater than zero degrees and less than ninety degrees. Therefore, the inclined surface can guide the flow of the condensed water in the water receiving tray 100, thereby improving the drainage efficiency of the water receiving tray 100.

As shown in fig. 4 and 5, in some embodiments of the present invention, the overflow hole 111 may be located at an upper middle portion of the inclined surface. It will be appreciated that the inner bottom wall of the drip tray 100 may include a first end portion and a second end portion, the first end portion being located upstream of the second end portion in the flow direction of the condensate water, the overflow hole 111 being provided at the first end portion. Therefore, the condensed water in the drain pan 100 is preferentially discharged through the drain pipe, and the condensed water is discharged through the overflow hole 111 only when the drain pipe fails to discharge the condensed water and the drain pan 100 stores the condensed water.

According to some embodiments of the present invention, the aperture of the overflow holes 111 gradually decreases or increases in the top-to-bottom direction. It should be noted that the "upward-downward direction" mentioned herein is understood to mean that the aperture of the overflow hole 111 gradually increases or gradually decreases in the flow direction of the condensed water. For example, in some embodiments of the present invention, the aperture of the overflow aperture 111 gradually increases in the top-to-bottom direction. Thus, the flow rate of the condensed water gradually increases while the condensed water flows through the overflow hole 111. As another example, in other embodiments of the present invention, the aperture of the overflow aperture 111 decreases gradually in the top-to-bottom direction. Therefore, the drainage efficiency of the condensed water can be ensured, the speed of the condensed water flowing into the overflow guide groove 320 can be reduced, and the condensed water is prevented from splashing after the condensed water collides with the overflow guide groove 320 at a high flow speed.

As shown in fig. 8 to 10, according to some embodiments of the present invention, the intermediate support 30 may have a cylindrical shape, and the overflow guide 320 may have a ring shape and surround the inner circumferential wall of the intermediate support 30 in the circumferential direction of the intermediate support 30. It is understood that the overflow guide 320 may have a ring shape, and the outer circumferential wall surface of the overflow guide 320 is connected to the inner wall surface of the intermediate support 30. Thereby, the air current can pass through the inner ring of the overflow chute 320, so that the configuration of the intermediate support 30 can be optimized, and the space utilization of the air conditioner 1 can be improved.

As shown in fig. 4, 5, 8 and 10, in some embodiments of the present invention, the intermediate support 30 may be provided with an annular baffle 300, the annular baffle 300 surrounds the inner circumferential wall of the intermediate support 30 in the circumferential direction of the intermediate support 30, one end of the annular baffle 300 in the axial direction is connected to the intermediate support 30, and the other end extends upward, and the annular baffle 300 and the inner circumferential wall of the intermediate support 30 define an overflow guide channel 320. Thereby, the construction of the overflow drain 320 can be simplified, and the installation cost of the intermediate support 30 can be reduced.

For example, as shown in fig. 8 to 10, the intermediate support 30 may be formed as a ring-shaped member having a horn shape, and the circumference of the contour line of the cross section of the intermediate support 30 is gradually increased or gradually decreased from one end to the other end of the intermediate support 30 in the axial direction. The ring guard 300 is fitted inside the intermediate supporter 30, one end of the ring guard 300 in the axial direction is connected to an inner wall surface of the intermediate supporter 30, and the other end of the ring guard 300 in the axial direction is spaced apart from the inner wall surface of the intermediate supporter 30 to form an overflow guide 320.

According to some embodiments of the invention, the annular baffle 300 and the intermediate support 30 may be an integral piece. It is understood that the ring guard 300 and the intermediate support 30 may be formed in one piece by a mold. Thereby, the coupling stability of the ring baffle 300 to the intermediate support 30 can be secured, so that the structural stability of the overflow drain 320 can be secured.

As shown in fig. 4, 5, 8 and 10, according to some embodiments of the present invention, the overflow guide 320 may be located below the overflow hole 111, the overflow guide 320 has a through hole 321, and the humidification module is located below the through hole 321. It will be appreciated that the through hole 321 may extend through the overflow channel 320, and the condensed water in the drip tray 100 may flow from the overflow hole 111 to the overflow channel 320 under the action of gravity, and the condensed water in the overflow channel 320 may pass through the through hole 321 and flow to the humidification module under the action of gravity. Therefore, the overflow hole 111, the overflow guide groove 320 and the through hole 321 can form a safe channel under the condition that the drain pipe is blocked and the water-receiving tray 100 can not drain normally, so as to guide the condensed water to drain out of the water-receiving tray 100, thereby preventing the condensed water from flowing into the electric control box 210 to cause safety accidents.

As shown in fig. 8 and 10, in some embodiments of the present invention, the through hole 321 may be disposed in the ring-shaped baffle 300, and the through hole 321 penetrates through the ring-shaped baffle 300. For example, in some examples of the invention, the free end of the ring baffle 300, i.e., the end of the ring baffle 300 spaced from the intermediate support 30, has a notch that may be configured to form the through-hole 321.
