Description

Water-gas separation structure of range hood Technical Field The utility model belongs to the technical field of range hoods, and relates to a water-gas separation structure of a range hood. Background The range hood is a household appliance for sucking and cleaning the cooking fume generated in a household kitchen, and is developed from an initial top-suction range hood to a side-suction range hood through long-term development of the range hood, and the range hood is not limited to a simple tool for removing the cooking fume in the kitchen, but is added with more entertainment functions and use functions. However, since a large amount of oil dirt is accumulated on the flue and the impeller of the fan after the range hood is used for a long time, the oil dirt can affect the fume extraction efficiency, so the range hood needs to be cleaned regularly, and the range hood free of disassembly and self cleaning appears on the market. The cooking device comprises a cleaning device for cleaning impellers and filter screens of a fan system, the cleaning device comprises a cleaning medium supply pipe and a nozzle, the cleaning medium supply pipe extends along the left-right direction, the nozzle is arranged on the cleaning medium supply pipe, the cleaning device is designed into a form of externally connected tap water pipeline, tap water is connected to one end of a water inlet electromagnetic valve through a water inlet pipe, the other end of the water inlet electromagnetic valve is connected with a first heating module, an outlet of the heating module is directly or indirectly connected to the cleaning electromagnetic valve, the cleaning electromagnetic valve is connected with each cleaning medium supply pipe through a hose, a normally open electromagnetic valve is arranged at the bottom of a bellows, an oil leakage hole is formed at the lowest position of the volute, and the normally open electromagnetic valve corresponds to the oil leakage hole and can be opened or closed. When the range hood is cleaned, tap water is sprayed out from a nozzle on a supply pipe, cleaning liquid flows into a volute below to soak an impeller, and when the impeller is soaked and needs to be drained, an oil leakage hole is opened through an electromagnetic valve at the bottom to drain water. Since the kitchen usually has only a drain pipe connected to the sink, the oil leakage hole is communicated to the drain pipe for draining. The internal environment of the range hood is severe, particularly, the bottom of the volute is adhered with stubborn greasy dirt, the temperature is high during fume extraction, the reliability and the service life of electronic components such as an electromagnetic valve are low, even if a spring type one-way valve is used, the electronic components can fail due to the adhesion of the greasy dirt, but if an on-off control piece is not arranged at the position, peculiar smell in a blow-off pipe can enter a room through oil leakage Kong Fanliu to the range hood when the range hood does not work. Disclosure of Invention The utility model aims to solve the problems in the prior art, and provides a water-gas separation structure of a range hood, which can ensure the use reliability and simultaneously prevent peculiar smell from flowing back into a room. The utility model can be realized by the following technical scheme that the range hood comprises a flue shell provided with a fume suction inlet and a fume exhaust pipe communicated with the flue shell, and is characterized in that the bottom of the flue shell is also communicated with the fume exhaust pipe through a drain pipe, the water-gas separation structure comprises a drain outlet which is arranged at the bottom of the fume exhaust pipe and faces downwards, the bottom of the fume exhaust pipe is also provided with a water storage box, the drain outlet is relatively communicated with an inner cavity of the water storage box below, the side wall of the water storage box is provided with a drain interface higher than the inner bottom surface, the fume exhaust pipe is also provided with a baffle plate which downwards extends into the water storage box, the drain outlets at two sides are isolated from the drain interface, the lower edge of the baffle plate is lower than the drain interface, and a water passing gap is reserved between the lower edge of the baffle plate and the inner bottom surface of the water storage box. The drain outlet on the smoke exhaust pipe is communicated with the water storage box, the drain port on the side wall of the water storage box can be connected with a drain pipe of a kitchen, and when the smoke exhaust pipe is used, the smoke exhaust pipe is used for exhausting smoke through the smoke exhaust inlet, and the smoke is exhausted outdoors. The sewage generated during the cleaning of the range hood is discharged into the smoke exhaust pipe from the drain pipe at the bottom of the flue shell, and the sewage in the smoke exhaust pi
