Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
the first embodiment of the invention provides a water-vapor separation mechanism, which comprises at least one water-vapor separation sheet 1 as shown in fig. 1 and 6, wherein a hydrophilic layer 2 and a hydrophobic layer 3 are arranged on the water-vapor separation sheet; when steam passes through the water-vapor separation sheet, a part of moisture contained in the steam stays on the hydrophilic layer 2, and a part of the moisture forms water drops on the hydrophobic layer 3 to roll, so that the steam slides down from the water-vapor separation sheet 1 and flows back to the inside of the steam cooking device.
By adopting the structure, because the contact angle between the hydrophilic layer 2 and water is small, the water on the hydrophilic layer 2 can be quickly flattened, and the contact angle between the hydrophobic layer 3 and the water is large, water on the hydrophobic layer 3 is easy to form water drops; like this, when the steam that contains saturated moisture passes through the steam separation piece, at first some moisture has formed the drop of water on hydrophobic layer 3 to the roll backward flow, another part moisture is stained with and is detained on hydrophilic layer 2 by hydrophilic layer 2, then steam is finally discharged from the gas vent, the effectual steam separation that has realized, moisture content significantly reduces in the steam of discharging like this, the difficult condensation drop of surface of cooking device, also be difficult for producing mould in the kitchen.
As shown in fig. 1 and 2, the present embodiment further includes a steam trap 4 disposed at the front of the moisture separation sheet 1. Thus, the steam baffle plate 4 can increase the contact area with the steam and delay the discharge and emission speed of the steam, so that the moisture in the steam can be fully treated.
The steam baffle 4 is provided with a hydrophilic layer 2 and a hydrophobic layer 3. This may further reduce the moisture in the exhaust steam.
The steam baffles 4 are arranged at the lower sides of the water-steam separation sheets 1 and are concave downwards, and the longitudinal sections of the steam baffles 4 are trapezoid-like; this further increases the contact area with the steam and allows the beads to slide down and flow back through the steam shield 4.
Each water-vapor separation piece 1 is provided with three rows and ten columns of steam baffles 4, namely each water-vapor separation piece 1 is provided with thirty steam baffles 4, so that more steam baffles 4 can be arranged, the layout is more standard, and the steam-vapor separation effect of the steam baffles 4 can be more effectively increased.
The distance between two adjacent steam baffles 4 is 3-10mm, and the preferred distance is 5mm in the embodiment; the number of the steam baffles 4 on the water-steam separation sheet 1 is increased while the area of the hydrophobic layer 3 is ensured.
The height of the steam baffle is 2-2.5 mm; therefore, the steam baffle plate 4 can further prolong the flow path of steam and increase the effect of water-steam separation.
The upper surface and the lower surface of the water-vapor separation sheet 1 are both provided with the hydrophilic layer 2 and the hydrophobic layer 3, so that the water-vapor separation effect can be further increased.
As shown in fig. 1, the tail part of the water-vapor separation sheet 1 is provided with a hydrophilic layer 2, and the front part of the water-vapor separation sheet 1 is provided with a hydrophobic layer 3.

This prevents the remaining water from remaining in the remaining water collecting box 6 for a long period of time.
The contact angle of the hydrophilic layer 2 and water is less than 30 degrees, so that water can quickly disperse and flatten on the hydrophilic layer 2; the hydrophobic layer 3 has a contact angle with water of more than 150 deg., which enables water to effectively form a water droplet on the hydrophobic layer 3.
The hydrophilic layer 2 can increase the surface energy of the water-vapor separation sheet 1, promote the contact with water and make the water quickly spread and flatten. The method for testing the water cleanability of the hydrophilic layer 2 comprises the following steps: lightly painting on the surface of the hydrophilic layer 2 by using an oily pen, standing for 5 minutes, then spraying water at the writing marks, and erasing by using a wet cloth and applying a vertical acting force below 2N on the surface after 8 seconds, wherein the writing is completely clean.
The hydrophobic layer 3 can form a nanoscale concave-convex emulsion structure on the surface of the water-vapor separation sheet 1, so that when water passes through, rolling similar to dew on lotus leaves can occur.
The water-vapor separation sheets 1 are arranged from top to bottom, the distance between the upper water-vapor separation sheet and the lower water-vapor separation sheet is H, the value range of H is 3-4mm, and the preferred value of the H is 3.5 mm. Therefore, the steam can pass through the steam-water separation sheet 1 more densely, so that the steam-water separation sheet 1 can fully treat the moisture in the steam.
The thickness of the moisture separation sheet 1 is 0.3 to 2mm, and the thickness of the present embodiment is preferably 0.5 mm. The thickness enables the water-vapor separation sheet 1 to dissipate heat better, and is beneficial to volatilization of moisture on the hydrophilic layer 2.
As shown in fig. 5, in the present embodiment, five moisture separation sheets 1 are preferably provided, which can ensure that the moisture separation mechanism of the present embodiment can separate more moisture.
The water-vapor separation sheet 1 is obliquely arranged, the inclination angle is A, and the value range of A is 3-15 degrees, and the preferred value of the embodiment is 10 degrees; the water drops on the hydrophobic layer 3 can be better refluxed, and meanwhile, the steam is fully contacted with the water-steam separation sheet 1 and the steam baffle plate 4.
The working process of the embodiment is as follows:
steam is discharged from the left outlet and the right outlet of the steam discharging pipe 7, passes through the front end of the water-steam separating sheet 1 and the steam baffle 4, part of water is adhered to the hydrophilic layer 2 and stays on the hydrophilic layer 2, is spread on the hydrophilic layer 2 and is volatilized rapidly, the other part of water forms water drops on the hydrophobic layer 3 and flows back to the residual water recycling box 6 in a rolling mode, and then the steam is discharged to the outside of the steam cooking device from the exhaust port; the residual water in the residual water recovery hole 62 of the residual water recovery box 6 flows into the residual water recovery pipe and finally flows back into the inner cavity of the steam cooking device. Thus, the steam-water separation of the steam is realized, and the moisture content in the discharged steam is reduced.
Example two:
