Accompanying drawing 2 is the use state figure of the utility model.

Detailed ways:

The electric steamer with reflux system is shown in attached drawings 1 and 2. It includes the main body of the electric steamer 1. The main body 1 of the electric steamer is provided with a steam extraction channel 2. The steam extraction channel 2 includes a steam inlet 3 and a steam outlet. The port 4, the steam inlet port 3 and the steam outlet port 4 are respectively arranged at the two ends of the steam extraction channel 2, and the steam extraction channel 2 is provided with an extraction fan 5.

At least one steaming layer 7 is placed on the upper end of the electric steamer.

The steam extraction channel 2 is provided with a steam baffle 6 which can only be opened in one direction. The steam baffle 6 can prevent the steam in the steam outlet 4 from flowing backward, and prevent the steam in the steam outlet 4 from directly flowing into the extraction fan 5 .

The steam baffle 6 is a partition that can seal the steam extraction channel 2, one end of the steam baffle 6 is hinged on the inner wall of the steam extraction channel 2, the other end of the steam baffle 6 is a free end, and the steam baffle 6 is set in the steam extraction channel 2. There is a limit device for preventing the steam baffle 6 from opening toward the steam inlet 3. When the steam baffle 6 is closed, the steam extraction channel 2 is sealed, and when the steam baffle 6 is opened toward the steam outlet 4, the steam extraction channel is connected. 2.

The limiting device is a limiting block fixed on the inner wall of the steam extraction channel 2 or a stepped limiting body protruding from the inner wall of the steam extraction channel 2 .

Of course, the steam baffle 6 can also be a split structure, the steam baffle 6 includes two split baffles, the outer ends of the two baffles are respectively hinged on the inner wall of the steam extraction channel 2, and the two baffles The inner ends of the two baffles are respectively free ends, and the limit devices for preventing the two baffles from opening toward the steam inlet 3 are respectively or separately provided in the steam extraction channel 2, and the steam extraction is sealed when the two baffles are closed. Channel 2, when one or two baffles are opened toward the steam outlet 4, the steam extraction channel 2 is connected. The limiting device is a limiting block fixed on the inner wall of the steam extraction channel 2 or a stepped limiting body protruding from the inner wall of the steam extraction channel 2 .

In the steam extraction channel 2, the steam inlet 3 is flat or bell-shaped, and the transverse section of the steam inlet 3 is circular, square or oval; the steam outlet 4 is flat or horn-shaped. Port shape; the transverse section of the steam outlet 4 is circular, square or elliptical.

In the steam extraction channel 2, the steam outlet 4 is tilted upward, and the steam outlet 4 is close to the side wall of the electric steamer; the steam inlet 3 is tilted upward, and the steam inlet 3 is close to the side wall of the electric steamer The wall; the steam extraction channel 2 is "V", "U" or arc-shaped; the steam inlet 3 and the steam outlet 4 of the steam extraction channel 2 form an included angle of 180 degrees in the horizontal direction.

Of course, the steam inlet 3 may also include a plurality of openings communicating with the small steam inlets, and the small steam inlets are arranged in parallel or radially. Or, the openings of the small steam inlets are connected, or the openings of the small steam inlets are not connected.

Similarly, the steam outlet 4 may also include a plurality of small steam outlets connected by openings, and the small steam inlets are arranged in parallel or radially. Or, the openings of the small steam inlets are connected, or the openings of the small steam inlets are not connected.

The extraction fan 5 is arranged at the bottom of the extraction channel 2 , and the extraction fan 5 is arranged near the steam inlet 3 .

When the extraction fan 5 works, a negative pressure is formed in the steam inlet 3 of the extraction channel 2, and the extraction fan 5 pushes the steam baffle 6 away by the air blown out. On the other hand, due to the negative pressure, the steam layer The steam near the steam inlet 3 in 7 is sucked into the steam extraction channel 2, and the steam passes through the steam baffle 6 in the steam extraction channel 2 to the steam outlet 4, and the steam sucked into the steam extraction channel 2 from The steam outlet 4 is sprayed out. Since the steam outlet 4 is tilted up, and the steam outlet 4 is close to the side wall of the electric steamer, the steam ejected from the steam outlet 4 will continue to flow vertically upward. The steam will quickly pass through each steam layer 7 upwards. When the steam reaches the top of the top steam layer 7, the steam gathers above the steam outlet 4 to form the first high-pressure steam zone, and the steam there begins to flow toward the steam layer. 7 The low-pressure area flows, and the steam also flows to the side where the steam inlet 3 is located. Similarly, when the steam reaches the side wall of the electric steamer again, the steam forms a second steam high-pressure area above the steam inlet 3. The second steam high-pressure area is located above the steam inlet 3. Since the space near the steam inlet 3 is under negative pressure, the steam flows from the second steam high-pressure area to the steam inlet 3 under the action of negative pressure. In the process, the individual steam layers 7 are also passed through, after which the steam is sucked into the steam channels 2 again. The steam circulates continuously in this way, and the steam in the steaming layer 7 forms a continuously circulating steam flow, so that the steam temperature in each area in the steaming layer 7 reaches equilibrium quickly, and the transformation time of the steam temperature from unbalanced to balanced is extremely short. The utility model is fast and effective in controlling the balance of steam temperature, and has a reasonable design layout, simple and compact structure, and takes up little space.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
