A guide cover 3 is arranged in the steam channel, and when the steam flows in the steam channel, the steam is blocked by the guide cover 3. Because the densities of the gas and the liquid are different, moisture in the water vapor can be attached to the outer wall of the air guide sleeve 3 and fall into the water cavity 101 of the water tank 1 under the action of gravity, and the gas in the water vapor can bypass the air guide sleeve 3 and continuously flow in the steam channel through the first flow channel, so that the water vapor and the water vapor are separated.
Because the air guide sleeve 3 is arranged in the steam channel and occupies a part of the space for the steam to flow, the air guide sleeve 3 can prevent the steam from flowing, the conveying time of the steam is prolonged, and the working efficiency of the steam generator is affected. Therefore, in the application, the radial width of the air guide sleeve 3 is gradually increased along the flow direction of the water vapor, on one hand, the water adhered to the outer wall of the air guide sleeve 3 can be quickly dropped into the water cavity 101 of the water tank 1 from the bottom of the air guide sleeve 3; on the other hand, the gas in the water vapor bypasses the air guide sleeve 3, and when the gas continuously flows in the steam channel through the first flow channel, the obstruction to the gas flow is reduced, so that the fluidity of the gas is ensured, and the working efficiency of the steam generator is improved.
In this embodiment, the steam channel includes a conduit 5 and a drainage cover 6, the drainage cover 6 is connected to the water tank 1 and the conduit 5, so as to guide the steam in the water tank 1 into the conduit 5, the steam flows along the conduit 5 to the cooking cavity, and the caliber of the drainage cover 6 gradually decreases along the flow direction of the steam. The steam channel comprises a guide pipe 5 and a drainage cover 6, the drainage cover 6 is positioned between the water tank 1 and the guide pipe 5, the water tank 1 is communicated with the guide pipe 5, so that water vapor in the water cavity 101 of the water tank 1 flows into the guide pipe 5 through the drainage cover 6 and then enters the cooking cavity through the guide pipe 5. It is envisioned that: in the application, the inner diameter of the guide pipe 5 is smaller than the caliber of the water cavity 101 of the water tank 1, and the caliber of the drainage cover 6 is gradually reduced along the flow direction of the water vapor because the drainage cover 6 is used for guiding the water vapor in the water cavity 101 of the water tank 1 into the guide pipe 5, so that the caliber of the drainage cover 6 gradually contracts from one end connected with the water tank 1 to one end connected with the guide pipe 5, the guiding effect of the drainage cover 6 on the water vapor is better, and the flow of the water vapor in a vapor channel is accelerated.
In this embodiment, the air guide sleeve 3 is located in the air guide sleeve 6, and a first flow channel is formed between the inner wall of the air guide sleeve 6 and the outer wall of the air guide sleeve 3. In the foregoing, the inner diameter of the conduit 5 is smaller than the diameter of the water chamber 101 of the water tank 1, and the flow-guiding hood 6 is gradually reduced from the end connected to the water tank 1 to the end connected to the conduit 5, so that the partial diameter of the flow-guiding hood 6 is larger than the inner diameter of the conduit 5. In the application, the guide cover 3 is arranged in the guide cover 6, and a first flow passage is formed between the inner wall of the guide cover 6 and the outer wall of the guide cover 3, so that the radial width of the guide cover 3 is not limited by the inner diameter of the guide pipe 5, and the water-steam separation effect is ensured; on the other hand is in order to guarantee the bore of first runner to guarantee the mobility of gas, promote this steam generator's work efficiency.

The steam generator further comprises a motor assembly and a pressurizing piece, wherein the pressurizing piece is arranged in the steam channel, and the motor assembly is used for driving the pressurizing piece to rotate. Because the radial width of the pressurizing piece is reduced along the flow direction of the steam, when the motor assembly drives the pressurizing piece to rotate, the pressure generated at the upstream of the pressurizing piece is high, and the pressure generated at the downstream of the pressurizing piece is low, so that the pressure difference between the upstream and the downstream of the pressurizing piece forms the pressurizing, the flow of the steam in the steam channel is quickened, the fluidity of the steam in the steam channel is further strengthened, and the working efficiency of the steam generator is improved.
In this embodiment, the pressurizing member includes a plurality of stages of impellers 7, the plurality of stages of impellers 7 are arranged along the flow direction of the water vapor, and the radial widths are sequentially reduced, and the motor assembly drives the plurality of stages of impellers 7 to rotate synchronously. The pressurizing piece comprises a multi-stage impeller 7, the multi-stage impeller 7 is arranged in the guide pipe 5, and water vapor reaches the position of the multi-stage impeller 7 after passing through a first flow passage between the inner wall of the drainage cover 6 and the outer wall of the drainage cover 3. The multistage impeller 7 at least comprises a first impeller 701 and a second impeller 702, and the motor assembly drives the first impeller 701 and the second impeller 702 to rotate synchronously. The first impeller 701 and the second impeller 702 are arranged along the flow direction of the water vapor, and the radial widths decrease in sequence, i.e., in the flow direction of the water vapor, the second impeller 702 is located downstream of the first impeller 701, and the diameter of the first impeller 701 is larger than the diameter of the second impeller 702.
It is envisioned that: the air blowing direction of the first impeller 701 is set toward the second impeller 702, and the first impeller 701 and the second impeller 702 form a double impeller structure. Since the radial width of the first impeller 701 is greater than the radial width of the second impeller 702, when the rotational speeds of the first impeller 701 and the second impeller 702 are the same, the edge linear speed of the first impeller 701 when rotating is greater than the edge linear speed of the second impeller 702 when rotating, so that the pressure formed by the first impeller 701 is greater than the pressure formed by the second impeller 702, and further, the pressure difference between the first impeller 701 and the second impeller 702 forms a boost pressure, and the vapor is pushed to sequentially pass through the first impeller 701 and the second impeller 702.
In the rotation process of the first impeller 701 and the second impeller 702, the rotation of the fan blades forces the water vapor to rotate, acting on the water vapor to increase the momentum of the water vapor, and sucking the water vapor into the second impeller 702 under the action of the pressure difference between the first impeller 701 and the second impeller 702, so that the water vapor continuously passes through the first impeller 701 and the second impeller 702, the flow of the water vapor is accelerated, and the speed increase of the water vapor is realized. In the present application, the multistage impeller 7 is not limited to the double impeller structure composed of the first impeller 701 and the second impeller 702, but may be a double impeller structure composed of the first impeller 701 and the second impeller 702, and the third impeller and the fourth impeller, and the number of impellers specifically included in the multistage impeller 7 may be determined according to actual production conditions.
In this embodiment, the steam channel forms a receiving chamber at the location of the pressurizing member, and when pressurizing is performed by using the multi-stage impeller 7, the receiving chamber is an impeller chamber 703 formed at the location of the multi-stage impeller 7 by the duct 5. The impeller chamber 703 is located at the periphery of the multistage impeller 7, and the caliber of the impeller chamber 703 gradually decreases along the flow direction of the water vapor in the conduit 5, on one hand, the water vapor in the conduit 5 is more quickly guided to the position of the multistage impeller 7, so that the flow of the water vapor in the conduit 5 is accelerated; on the other hand, the impeller chamber 703 is matched with the multi-stage impeller 7 to form pressurization, so that water vapor is better pushed to flow in the guide pipe 5, the fluidity of gas is further ensured, and the working efficiency of the steam generator is improved.
In this embodiment, the steam channel is provided with the guide body 8, and a second flow channel through which water vapor passes is formed between the inner wall of the steam channel and the outer wall of the guide body 8, and the water vapor flows from the second flow channel to the multi-stage impeller 7, so that the radial width of the guide body 8 gradually increases along the flow direction of the water vapor. The steam channel is provided with a plurality of sections of flow channels along the flow direction of the steam, a first flow channel is formed between the inner wall of the drainage cover 6 and the outer wall of the guide cover 3, the steam in the water tank 1 is blocked by the guide cover 3, moisture in the steam adheres to the outer wall of the guide cover 3 and falls into the water cavity 101 of the water tank 1 under the action of gravity, gas in the steam bypasses the guide cover 3, and continues to flow in the steam channel through the first flow channel to perform the water-steam separation of the first steam.
The second flow channel is formed between the inner wall of the conduit 5 and the outer wall of the guide body 8, and the water vapor flowing in the vapor channel is continuously blocked by the guide body 8 through the first flow channel, so that part of water remained in the water vapor is attached to the outer wall of the guide body 8 and falls into the water cavity 101 of the water tank 1 under the action of gravity, and the gas in the water vapor bypasses the guide body 8 and flows to the multistage impeller 7 through the second flow channel to perform the water vapor separation of the second time, thereby further ensuring the water vapor separation effect. The steam flowing to the multistage impeller 7 accelerates in the steam channel under the supercharging action of the multistage impeller 7, so that the fluidity of gas is enhanced, and the working efficiency of the steam generator is improved.
In the application, the steam channel is also provided with the water-vapor separation roller 4, the water-vapor separation roller 4 is of a structure with a cavity therein and an opening at the top of the cavity, the outer wall of the water-vapor separation roller 4 is provided with a plurality of through holes for communicating the cavity with the outside, and the motor component drives the water-vapor separation roller 4 to rotate. It is envisioned that: a third flow passage is also arranged between the inner wall of the conduit 5 and the outer wall of the water-vapor separation roller 4. When the water vapor in the vapor channel is pressurized by the multi-stage impeller 7, the water vapor flows to the third flow channel and then enters the cavity of the water vapor separation roller 4 through the through holes on the outer wall of the water vapor separation roller 4.
When the motor component drives the water-vapor separation roller 4 to rotate, the centrifugal force generated by the water-vapor separation roller 4 throws the water vapor entering the water-vapor separation roller 4 away from the axial center position of the water-vapor separation roller 4. Because the density of the gas and the density of the liquid are different, the centrifugal force of the liquid is larger than that of the gas, so that the moisture in the vapor can be thrown to the inner wall of the vapor-water separation roller 4 and attached to the inner wall of the vapor-water separation roller 4, and the moisture drops into the water cavity 101 of the water tank 1 under the action of gravity, and the gas in the vapor continuously flows in the vapor channel through the opening at the top of the cavity of the vapor-water separation roller 4, thereby further ensuring the vapor-water separation effect.
In this embodiment, the booster includes a turbine 9, the radial width of the turbine 9 gradually decreases along the flow direction of the water vapor, and the motor assembly drives the turbine 9 to rotate. In the present application, the pressurizing member may be a turbine 9 provided in the duct 5, the radial width of the turbine 9 being gradually reduced in the flow direction of the water vapor, so that the turbine 9 forms a structure with a wide bottom and a narrow top. When the turbine 9 is used for pressurization, the accommodating chamber formed by the steam passage at the position of the pressurizing member is a turbine chamber 901 formed by the duct 5 at the position of the turbine 9. The turbine chamber 901 is located at the periphery of the turbine 9, and the caliber of the turbine chamber 901 gradually decreases along the flow direction of the water vapor in the conduit 5, so that when the motor assembly drives the turbine 9 to rotate, the turbine chamber 901 and the turbine 9 are matched, the upstream pressure and the downstream pressure of the turbine 9 are high, the pressurization is formed, the water vapor injection is realized, and the flow of the water vapor in the conduit 5 is accelerated.

It is envisioned that: in the present application, the multi-stage impeller 7 and the turbine 9 are used for supercharging, and may be used alone or in combination. When the multi-stage impeller 7 and the turbine 9 are combined, the guide body 8, the multi-stage impeller 7, the water vapor separation roller 4 and the turbine 9 can be sequentially arranged in the guide pipe 5 along the flow direction of the water vapor, so that the water vapor entering the guide pipe 5 flows to the multi-stage impeller 7 through the second flow passage between the inner wall of the guide pipe 5 and the outer wall of the guide body 8; after the acceleration of the multistage impeller 7, the water vapor enters the water-vapor separation roller 4 through a third flow passage; after water-vapor separation is carried out through the water-vapor separation roller 4, water vapor flows to the turbine 9 through the water-vapor separation roller 4, and the turbine 9 accelerates the water vapor again, so that the fluidity of the water vapor is ensured, and the working efficiency of the steam generator is improved.

When the steam flows in the conduit 5, the multistage impeller 7 is used for primarily pressurizing the steam, so that the flow of the steam in the conduit 5 is accelerated, and the steam rapidly enters the steam-water separation roller 4; after the steam passes through the steam-water separation roller 4, the kinetic energy of the turbine 9 is converted into the pressure energy of the steam under the action of the turbine 9, so that the steam is accelerated to be sprayed out.
The motor cover 12 surrounds the periphery of the motor 10 and is used for isolating the motor 10 from the water vapor in the guide pipe 5 and preventing the water vapor in the guide pipe 5 from contacting with the motor 10, so that the motor 10 is protected, and corrosion of the motor 10 by the water vapor is reduced. Meanwhile, the steam is subjected to steam-water separation through the steam-water separation roller 4, the guide cover 3 and the guide body 8, so that less water in the steam reaching the motor 10 is ensured, and the motor 10 is better protected.

When the water vapor flows in the conduit 5, the water vapor is initially pressurized by the multistage impeller 7, so that the water vapor rapidly enters the water-vapor separation roller 4 in a manner of accelerating the flow of the water vapor in the conduit 5; after the steam passes through the steam-water separation roller 4, the kinetic energy of the turbine 9 is converted into the pressure energy of the steam under the action of the turbine 9, so that the steam is accelerated to be sprayed out.
At this time, since the motor 10 is disposed below the water cavity 101 of the water tank 1, there is no possibility of contact with water vapor, so there is no need to dispose the motor cover 12 outside the motor 10, the motor 10 has better anti-interference performance in the actual use process, and gaps may exist between the air guide cover 3, the air guide body 8 and the rotating shaft 11 in this way, and water vapor easily flows to the water-vapor separation roller 4 through the gaps, so as to affect the overall water-vapor separation effect.
