The air conditioner effectively cooperates with the air conditioner outdoor unit to run, so that the refrigeration and heating circulation of the air conditioner is completed, and the cold and hot regulation of the indoor temperature is realized.

The indoor unit of the air conditioner generally comprises a shell, an indoor unit heat exchanger and an air supply fan. The casing comprises a framework for supporting the fan of the indoor unit and the heat exchanger of the indoor unit, and a housing which is covered on the framework and is provided with an air inlet and an air outlet. Generally, the front side of the casing forms the front panel of the indoor unit and has an air outlet opening at the front side. Since the structure of the housing of the indoor unit of the air conditioner is known to those skilled in the art, it will not be described herein.

The indoor unit heat exchanger exchanges heat with air flowing therethrough to change the temperature of the air flowing therethrough. The air supply fan is used for promoting the ambient air entering from the air inlet to flow to the indoor unit heat exchanger and promoting the heat exchange air after the heat exchange of the indoor unit heat exchanger to flow towards the air outlet, so that the heat exchange air is discharged to the working environment of the indoor unit.

The indoor unit heat exchanger is used as a part of a refrigeration system. The refrigeration system can be realized by using a compression refrigeration cycle, and the compression refrigeration cycle realizes heat transfer by using a compression phase change cycle of a refrigerant in a compressor, a condenser, an evaporator and a throttling device. In the air conditioner, the refrigerating system can also be provided with a four-way valve to change the flow direction of the refrigerant, so that the heat exchanger of the indoor unit is used as an evaporator or a condenser to realize the refrigerating or heating function. Since the compression refrigeration cycle of the air conditioner is well known to those skilled in the art, the operation principle and structure thereof will not be described herein.

As shown in fig. 1 to 6, the exhaust and drain combined pipe assembly 20 of the air conditioner 10 of the present embodiment includes a drain assembly and an exhaust assembly 220. The drain assembly is used for draining condensed water of the air conditioner 10 to the outside. The exhaust assembly 220 is communicated with the drainage assembly and is used for exhausting indoor foul air into the drainage assembly so that the indoor foul air is exhausted to the outdoor through the drainage assembly.

The drain assembly includes a main conduit 210. The main pipe 210 has one end connected to an indoor unit of the air conditioner 10 and the other end connected to an outdoor environment, and is used to discharge condensed water from the indoor unit. The drain pipe can be arranged from indoor to outdoor in a downward sloping mode so as to facilitate drainage of condensed water.

The exhaust assembly 220 includes an exhaust branch pipe 221 and a ventilation assembly. The exhaust branch pipe 221 communicates with the main line 210. The ventilation assembly is disposed in the exhaust branch pipe 221 for inducing the formation of a foul air flow. The foul air flow enters the main pipe 210 through the exhaust branch pipe 221 and is exhausted to the outside through the main pipe 210. The exhaust assembly 220 includes a ventilation fan 223 and a driving motor 224 for driving the ventilation fan 223 to rotate. The driving motor 224 drives the ventilation fan 223 to rotate to induce the formation of the foul air flow. The exhaust branch pipe 221 is disposed above the main pipe 210. The ventilation fan 223 is turned on in the exhaust state.

The exhaust and drainage composite pipe assembly 20 of the present embodiment further includes a switching valve assembly 30. The switching valve assembly 30 is disposed on the main pipe 210 upstream of a connection of the exhaust branch pipe 221 with the main pipe 210. The switching valve assembly 30 includes a flow blocking baffle 320 and a baffle driving device 310. The choke baffle 320 is disposed within the main conduit 210. The baffle driving device 310 serves to drive the choke baffle 320 to rotate so that the switching valve assembly 30 is switched between the drainage state and the exhaust state.

As shown in fig. 4. In the drainage state, the choke baffle 320 flows in parallel to the direction of the condensed water, which flows along the lower portion of the main pipe 210 to the outside. As shown in fig. 6, in the exhaust state, the choke plate 320 is perpendicular to the flow direction of the condensed water, the condensed water is blocked upstream of the choke plate 320, and the ventilation fan 223 is turned on, so that the flow of the foul air flows from the exhaust branch pipe 221 into the main pipe 210 to flow to the outside. The flow-blocking baffle 320 may prevent the backflow of the foul air toward the indoor unit in the discharge state.

The main duct 210 is provided with an installation opening 210a for installing the choke baffle 320. The mounting ports 210a are shaped according to the shape of the baffle 320. The driving rod of the flapper driving unit 310 protrudes into the mounting opening 210a to be connected to the choke flap 320, so that the flapper driving unit 310 drives the choke flap 320 to rotate. The baffle drive device 310 is disposed near the exhaust branch pipe 221. The composite tubing assembly 20 of the present embodiment further comprises a snap ring 410. The snap ring 410 is used for clamping the baffle plate driving device 310 and the exhaust branch pipe 221 so that the baffle plate driving device 310 and the exhaust branch pipe 221 are fixedly connected. The snap ring 410 may include a first snap portion and a second snap portion. The first clamping portion is used for clamping the baffle driving device 310, and the second clamping portion is used for clamping the exhaust branch pipe 221.

The exhaust assembly 220 also includes a ventilation enclosure 222. The ventilation housing 222 is provided at an air inlet of the exhaust branch pipe 221 to prevent foreign substances from entering the exhaust branch pipe 221. The ventilation housing 222 is provided with a plurality of through holes. The size and shape of the through holes can be set according to actual needs.

The ventilation enclosure 222 includes a converging section 2221. The converging section 2221 converges toward the air inlet direction close to the exhaust branch pipe 221, and is connected with the air inlet of the exhaust main pipe. The converging section 2221 is connected with the air outlet pipe of the exhaust branch pipe 221 through a screw thread. The ventilation casing 222 also includes a main body portion 2222. The body portion 2222 is located above the converging section 2221. The main body portion 2222 is cylindrical as a whole, and has a through hole formed therethrough.

The exhaust and drain combined pipe assembly 20 of the air conditioner 10 of the present embodiment includes a drain assembly and an exhaust assembly 220. The drain assembly is used to drain the condensed water of the air conditioner 10 to the outside. The air discharge assembly 220 is in communication with the water discharge assembly for discharging indoor foul air into the water discharge assembly such that the indoor foul air is discharged to the outside through the water discharge assembly.

Further, the exhaust and drain composite pipe assembly 20 of the air conditioner 10 of the present embodiment includes a drain assembly, a switching valve assembly 30, and an exhaust assembly 220. The drain assembly includes a main conduit 210. The exhaust assembly 220 includes an exhaust branch pipe 221 and a ventilation assembly.

The switching valve assembly 30 includes a choke baffle 320 and a baffle driving device 310. The choke baffle 320 is disposed within the main conduit 210. The baffle driving device 310 is used to drive the choke baffle 320 to rotate, so that the switching valve assembly 30 is switched between the drainage state and the exhaust state. In the drainage state, the baffle 320 flows in parallel to the condensed water. In the exhaust state, the baffle 320 flows perpendicular to the condensed water. The exhaust and drainage composite pipeline assembly 20 of the air conditioner 10 of the embodiment can be switched to a use state through the switching valve assembly 30, so that the use requirements of different scenes are met.
