For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] The following refers to Figures 1-5 A drainage structure of a high-power window type cooling and heating air conditioner is described according to some embodiments of the present application.

[0028] A drainage structure of a high-power window type cooling and heating air conditioner, comprising a case 1, the case 1 is divided into an indoor cavity 2 and an outdoor cavity 3; The cross-flow fan 4, the indoor heat exchanger 5, the electric heater 6 are arranged in the indoor cavity 2, and the air outlet 7 is arranged at the top of the indoor cavity 2. The axial flow fan 8, the compressor 9, the outdoor heat exchanger 10 are arranged in the outdoor cavity 3, the outdoor cavity 3 comprises a second bottom plate 11, and the compressor 9 is a 4.5-6.8kW high-power variable frequency compressor.

[0029] The second bottom plate 11 of the outdoor cavity 3 is raised to form a platform 13, and the edge of the platform 13 is surrounded by the side wall of the outdoor cavity to form a water collecting tray 14, and the bottom surface of the water collecting tray 14 is attached with a heating film. The indoor cavity 2 comprises a first bottom plate 15, and the horizontal position of the first bottom plate 15 is higher than that of the platform 13. The indoor cavity 2 is separated from the outdoor cavity 3 by a partition plate 16, and the indoor cavity 2 is provided with a second drain pipe 17 at the bottom thereof, which is led to the outdoor cavity 3 through the partition plate 16. The water collecting tray 14 of the outdoor cavity 3 is connected with a first drain pipe 18 through a drainage flow channel, and the first drain pipe 18 is located on the indoor side. The water collecting tray 14 and the drainage flow channel form an L-shaped groove outside the platform 13, and a temperature control drain valve 19 is arranged at the joint of the first drain pipe 18 and the water collecting tray 14. The temperature control drain valve 19 is provided with an elastic air bag 20, the elastic air bag 20 is connected with a valve rod 21, and the valve rod 21 is connected with a plug 22.

[0030] The axial flow fan 8 is vertically installed, and comprises fan blades 23 and an outer ring 24, and the fan blades 23 and the outer ring 24 are connected through a water hitting block 25. The axial flow fan 8 is an integral structure, and the bottom of the outer ring 24 is close to the platform 13 and is 1mm away from the surface of the platform 13.

[0031] Specifically, when the ambient temperature is high and the air conditioner is working in the cooling mode, the indoor heat exchanger 5 absorbs heat from the surrounding environment, and condensate water is generated on the surface of the indoor heat exchanger 5. The condensate water flows to the first bottom plate 15 of the indoor unit box 2, and when the condensate water accumulated on the first bottom plate 15 reaches a certain amount, it flows into the second drain pipe 17, enters the outdoor cavity 3 along the pipe, and flows to the platform 13. At this time, the ambient temperature is high, and the elastic air bag 20 in the temperature control drain valve 19 has the characteristics of thermal expansion and contraction. The elastic air bag 20 expands, and the valve rod 21 and the plug 22 are pressed down to block the hole of the first drain pipe 18, so that the condensate water cannot be discharged through the first drain pipe 18 and accumulates on the second bottom plate 11. When the condensate water accumulates to a certain amount, the liquid surface contacts the outer ring 24 and the water hitting block 25 of the axial flow fan 8. Since the axial flow fan 8 rotates at high speed when the air conditioner is working, the water hitting block 25 rotates around the central axis of the fan, and the water hitting block 25 continuously collides with the condensate water. The condensate water is thrown by the water hitting block 25 to the outdoor heat exchanger 10 and evaporates under the heat, thereby completing the drainage process. When the ambient temperature is low and the air conditioner is working in the heating mode, the outdoor heat exchanger 10 absorbs heat from the surrounding environment, and condensate water is generated on the surface of the outdoor heat exchanger 10. The condensate water flows to the second bottom plate 11 of the outdoor unit box 3 and collects in the water collecting tray 14. At this time, the ambient temperature is low, and the elastic air bag 20 in the temperature control drain valve 19 contracts, so that the valve rod 21 and the plug 22 move upwards to expose the hole of the first drain pipe 18, so that the condensate water is discharged into the indoor through the first drain pipe 18, thereby completing the drainage process. Since the bottom surface of the water collecting tray 14 and / or the drainage flow channel is attached with a heating film, the condensate water of the outdoor heat exchanger is guided to the indoor through the L-shaped groove and discharged, and the phenomenon of condensate water freezing into ice blocks does not occur.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
