[0020] Moreover, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as no conflict is constituted between each other.

[0021] An embodiment of the air conditioner shown in Figs. 1 and 2 includes a water receiving structure and a base 200, wherein the base 200 is a support and mounting base of the whole machine, and an air duct component (not shown in the figures), a heat exchange component (not shown in the figures), and an appearance component (not shown in the figures) are provided on the base 200; the water receiving structure is arranged on the base 200, the water receiving structure includes a housing 10, a lug 20 and a switch matching structure (not shown in the figure), the housing 10 is provided with a water catcher 11 and a drainage pipe 12, and the drainage pipe 12 is in communication with the water catcher 11 and extends out of the housing 10; the lug 20 is fixedly mounted on the housing 10; the switch matching structure is arranged on the base 200, and the lug 20 mates with the switch matching structure to switch the connecting passage between the water channel 11 and a water passage 300 of a bottom case of the air duct component.

[0022] The air conditioner is provided with a water catcher 11 and a drainage pipe 12 on the housing 10, and the drainage pipe 12 is in communication with the water catcher 11 and protrudes from the housing 10, thereby realizing communication between the water catcher 11 and the outside. Meanwhile, the lug 20 is fixedly mounted on the housing 10, the switch fitting structure is arranged on the base 200, and the lug 20 fits with the switch fitting structure so as to switch the connecting passage between the water catcher 11 and a water passage 300 of a bottom case of the air duct component, and further, when the air duct component is provided, the switch passage is opened. the water catcher 11 of the housing 10 is in communication with the water passage 300, and a water passage 300 receives the condensed water of the air duct component and can flow same into the water catcher 11, so as to discharge the water on the water passage 300; When the air duct component needs to be dismounted, the discharge pipe 12 need not be dismounted, and the connecting passage can be dismounted separately only by the switch matching structure, and when the discharge pipe 12 is blocked, the dirt is dismounted in the water catcher tank 11 or still blocked in the discharge pipe 12, thereby simplifying the dismounting operation workload and operation difficulty.

[0023] The switch matching structure is provided with an open position and a closed position, and the lug 20 can be moved between the open position and the closed position for opening or closing the connecting passage, and then the communication and separation between the water receiving structure and a water passage 300 can be realized through the matching between the switch matching structure and the lug 20. Specifically, as shown in Figs. 3 and 4, the switch matching structure includes a fixing seat 201, a fixing groove 202 with an opening at one end is provided on the fixing seat 201, a limiting plate 203 is provided on a bottom wall of the fixing groove 202 opposite to the opening, an abutting portion is provided on the limiting plate 203, and at least one guide rib 204 is provided on an inner wall of the fixing groove 202. The lug 20 is movably mounted in the fixing groove 202, and the limiting plate 203 defines the movement of the lug 20 between the open position and the closed position, so that after the lug 20 is provided in the fixing groove 202, the lug 20 can be moved between the open position and the closed position through a limiting fit between the limiting plate 203 and the lug 20.

[0024] As shown in Fig. 2, a limiting hole 21 is arranged on the lug 20 corresponding to the limiting plate 203, and the limiting hole 21 extends into the limiting hole 21 against the top to move against the opposite sides of the limiting hole 21 opposite with the bottom wall, so as to move the lug 20 between the open position and the closed position; Meanwhile, at least one guide groove 22 is arranged on the lug 20 corresponding to the guide rib 204, the guide rib 204 is arranged along the moving direction, the guide rib 204 slides in the guide groove 22, and then passes through the engagement between the guide rib 204 and the guide groove 22. The guiding effect of the lug 20 along a moving direction of the lug is achieved, and the stability of the lug 20 in the fixing groove 202 is also improved.

[0025] In order to realize the movement of the lug 20 between the open position and the closed position, a fixing positioning 23 is protruded from the lug 20 toward a bottom wall of the fixing groove 202, an elastic member (not shown) is sleeved on the fixing positioning 23, and the elastic member is compressed and retracted in the fixing groove 202. a biasing force of the elastic member in the direction away from a bottom wall is applied to the lug 20, that is, the lug 20 is subjected to the biasing force to exit the fixing groove 202, and when the housing 10 is not subjected to the external force, the lug 20 is kept in the open position by applying the biasing force to the lug 20, as shown in Fig. 5. In this case, the water receiving structure is in a communication state with the water passage 300. When the housing 10 is pressed, the elastic member is compressed, and the lug 20 is in the closed position, as shown in Fig. 6, at this time, the connecting passage is closed, that is, the air duct component can be detached separately. In the present embodiment, the elastic member is a spring.

[0026] In the present embodiment, in addition to the need to control the switch of the connecting passage between the water receiving structure and the water passage 300, it is often required to ensure that the connecting passage is opened and stable, that is, the stability of the communication state between the water receiving structure and the water passage 300 is required, and the housing 10 is funnel-shaped. When the lug 20 is in the open position, a notch of the water catcher 11 is communicated with the drainage port 301 on the water passage 300, thereby achieving communication between the water receiving structure and a water passage 300; Meanwhile, a limiting structure (not shown) is provided on the housing 10, and when the lug 20 is in the open position, the limiting structure limits the relative movement of the housing 10 and the water passage 300, thereby ensuring stability in the conductive state.

[0027] As an optional implementation, the limiting structure is a concave structure arranged on a slot wall 13 of the water catcher 11, and when the lug 20 is in the open position, the drainage pipe 12 where the drainage port 301 is located in the concave structure, and the concave structure restricts the drainage port 301 from moving in the dismounting direction of the water passage 300; When the lug 20 is in the closed position, the drainage pipe 12 slides out of the slot wall 13 along an outer edge of the concave structure, thereby limiting the relative movement between the housing 10 and a water passage 300 through the limiting structure.

[0028] Obviously, the above-described embodiments are merely examples made for clarity, and are not limited to the embodiments. Other variations or variations in different forms can also be made by those skilled in the art on the basis of the above description. All embodiments need not be exhaustive here. Apparently obvious variations or variations that are thus introduced are still within the scope of protection created by the present invention.
