The heating principle of the electric steamer in the prior art is that the heating device in the steamer converts water into high-temperature steam, and a high-temperature and high-pressure heating environment is formed inside the steamer. The steaming process will generate a lot of steam. Since the steam cannot be discharged in time, the steam temperature is high when discharged, which is easy to burn the user, and also brings a lot of inconvenience to the user. The exhaust structure and steam equipment provided by the present invention can solve the above technical problems and can be widely used in the technical field of steam equipment.

Example 1

As shown in FIG. 1 to FIG. 8 , an embodiment of the present invention provides an exhaust structure, including: an air guide structure and a fan 2 . The air guide structure includes a top plate 1, a cooling cover 3 and a bottom plate 4 arranged opposite to the top plate 1. At least a part of the air guide structure is provided with a cooling structure 11, and the air guide structure is provided with an air inlet B and an air outlet C, and the top plate 1 is far away from A cooling cover 3 is provided on one side of the bottom plate 4 . A fan 2 is provided at the air inlet B of the top plate 1 , and the fan 2 communicates with the air inlet B.

In the embodiment of the present invention, the air guide structure includes a top plate 1 , a cooling cover 3 and a bottom plate 4 arranged opposite to the top plate 1 , and a first air channel for steam to flow is formed between the top plate 1 and the bottom plate 4 . The top plate 1 is provided with a plurality of fixing pieces 8 on the outer periphery, and the bottom plate 4 is provided with screw holes that cooperate with the fixing pieces 8 . At least a part of the air guide structure is provided with a cooling structure. The cooling structure 11 is a plurality of raised structures formed on the inner wall of the air guide structure. The raised structures can be wave-shaped structures or concave-convex structures. There are many restrictions, mainly the protrusions arranged on the top plate can be protruded, and the protrusions themselves can be arranged in strips, blocks, or arranged in a matrix. The top plate 1 is disposed above the steam flow path, and the cooling structure 11 is disposed on the top plate 1 .

With this arrangement, when the exhaust structure works, after the steam enters the first air duct 7, the contact area between the steam and the top plate 1 will increase. Since the convex structure has the characteristics of a wave shape or a concave-convex structure, the output stroke of the steam can be lengthened, the water vapor can be effectively condensed, and the exhaust process of the steam equipment can be optimized.

Along the flow direction of the steam, the width and inner diameter of the top plate 1 gradually increase, so that the top plate 1 is arranged in an isosceles trapezoid. By increasing the width and inner diameter of the top plate along the flow direction of the steam, since the steam has a narrow width when entering from the steam inlet 10 of the air inlet B, the width is wider when the steam is blown to the air outlet C by the blower 2, and the steam is wider. The concentration of the steam becomes lower, so that the top plate 1 can better cool the steam, accelerate the condensation efficiency of the steam, and then optimize the exhaust process of the steam equipment.

In the embodiment of the present invention, the bottom plate 4 is disposed opposite to the top plate 1 and surrounds the top plate 1 to form a first air duct 7 .

Since the steam inlet 10 is arranged at the center of the bottom plate 4, the left and right parts of the steam device can be uniformly vented, the steam circulation speed is increased, the condensed water of the steam is not easy to gather in one part, and the user experience is improved.

As a variant embodiment, the bottom plate 4 can also be recessed in the center, where the condensed water formed by the steam is collected. Since the steam inlet 10 is provided in the central part of the bottom plate, the steam inlet 10 is communicated with the steam equipment that outputs steam through the steam pipe 5 .

By setting the cooling cover 3, a second air duct 6 is formed between the cooling cover 3 and the top plate 1, and the second air duct 6 is a cooling air duct. When the fan 2 is working, the wind generated by the fan 2 simultaneously flows from the first air duct 7 Passing through the second air duct 6 , the wind contacts the top plate 1 , so as to achieve the purpose of cooling the top plate 1 . When the cooling cover 3 cools the top plate 1, the temperature of the top plate 1 can be lowered. When the steam contacts the top plate 1, condensed water will be formed on the surface of the top plate 1, thereby reducing the temperature and humidity when the hot steam is blown out, ensuring that the user will not Hot steam and scalding, optimize user experience. The top plate 1 can be made of stainless steel or other materials with high thermal conductivity to ensure that the surface is kept at a lower temperature.

As a variant embodiment, the cooling cover 3 can also be other devices that directly cool the top plate 1 , such as liquid cooling equipment such as water cooling equipment, which only needs to play a condensation role. When other cooling devices are provided, it is only necessary to connect the fan 2 with the first air passage 7, and the condensation rate can be increased.

In this embodiment, the ventilation cover 12 is disposed between the cooling cover 3 and the fan 2 , and one end of the ventilation cover 12 covers the fan 2 and the other end covers the cooling cover 3 . Several fixing pieces 8 are provided on both sides of the ventilation cover 12 , the ventilation cover 12 and the bottom plate 4 are connected by the fixing pieces 8 , and a sealing piece is arranged between the ventilation cover 12 and the base plate 4 . The inner diameter of the ventilation hood 12 gradually increases along the airflow direction of the cooling air blown by the fan 2 . By setting the ventilation hood 12 , the cooling air blown by the fan 2 can completely enter the cooling hood 3 and the air guide structure, so as to prevent the cooling air from being emitted between the fan 2 and the cooling hood 3 , thereby improving the working efficiency of the fan 2 .

Of course, as another embodiment, the ventilation hood 12 and the cooling hood 3 can be integrally formed. In this way, the cooling air leaking from the ventilation hood 12 and the cooling hood 3 can be greatly reduced, so that more cooling air can be Acting on the first air duct 7 and the second air duct 6 can improve the cooling efficiency of the fan 2 .

The two sides of the fan 2 are provided with fixing parts 8 , the bottom plate 4 is provided with screw holes that cooperate with the fixing parts 8 , and the fan 2 and the base plate 4 are assembled by a screw structure. The screws pass through the fixing member 8 and the screw holes in turn to connect the fan 2 and the bottom plate 4 together.

In the embodiment of the present invention, the fan 2 can be a cross-flow fan 2 or a cooling fan 2 . The fan 2 communicates with the first air duct 7 and the second air duct 6 at the same time. When the wind generated by the fan 2 passes through the first air duct 7, it can quickly circulate the steam, and can also reduce the temperature of the steam through the generated cold air, thereby further improving the condensation effect. When the wind generated by the fan 2 passes through the second air duct 6, it can have a cooling effect on the top plate 1, and then the top plate 1 contacts the steam through the cooling structure 11, thereby condensing the steam.

When the steam equipment is working, the steam generated by the steam equipment is condensed and cooled through the exhaust structure, which can greatly reduce the discharged steam, and the reduced steam is discharged in the form of condensed water. In addition, after the exhausted steam passes through the exhaust structure, it is cooled by the cold air generated by the fan 2, which can reduce the temperature of the uncondensed steam, thereby preventing the user from being scalded by the high-temperature steam and improving the user experience.
