Further, the exhaust sheet is provided with a plurality of exhaust apertures, which are spaced apart from each other.
Further, the small vent holes each have a rounded profile.
The invention has the beneficial effects that:
1. the cooker cover comprises a cooker cover body and an exhaust piece, wherein the cooker cover body is provided with a mounting hole, the exhaust piece is mounted in the mounting hole, the exhaust piece comprises an exhaust piece and a side part, one end of the side part extends to the lower side of the cooker cover body, the other end of the side part is positioned above the outer surface of the cooker cover body, the exhaust piece is provided with an exhaust small hole and a water collecting concave part, and the exhaust small hole is positioned in the water collecting concave part. When cooking, food in the cooker is heated, formed water vapor overflows from the small exhaust holes of the exhaust sheet, and some water vapor is condensed on the exhaust sheet, condensed water drops are gathered at the water gathering concave parts of the exhaust sheet, and when enough water flows back into the cooker from the small exhaust holes under the action of gravity, on one hand, the condensed water drops are prevented from flowing along the cooker cover to cause the pollution of the cooker cover and even damage some parts of the cooker, on the other hand, a part of water of the cooked food can be kept, and the food can keep better nutrition and mouthfeel.
2. Further, the water collecting concave part comprises a side circumferential surface and a bottom, and the connecting position of the side circumferential surface and the bottom is in arc transition. Therefore, on one hand, water drops are prevented from being accumulated at the connecting part of the side peripheral surface and the bottom, and the water drops condensed on the side peripheral surface are favorably returned to the bottom along the smooth transition part; on the other hand, the stress at the joint of the side circumferential surface and the bottom is also reduced, so that the overall strength of the exhaust sheet is improved.
3. Further, the lateral circumferential surface comprises a lateral curved surface part connected with the bottom part, and the lateral curved surface part protrudes in a direction departing from the water collecting concave part. Thus, the side curved surface portion facilitates the water droplets condensed on the side circumferential surface to flow back to the bottom portion along the curved surface.

6. Further, the diameter of the mounting hole is 1.5-2.5 cm. On one hand, the mounting hole needs to have a large enough size to allow the exhaust member with the exhaust small hole to be mounted, on the other hand, the mounting hole needs to have a large enough size to facilitate the process of forming the exhaust small hole on the exhaust member, and on the other hand, the mounting hole needs to have a large enough exhaust channel area to meet the requirement of discharging more water vapor of the electric cooking machine, so the diameter of the mounting hole is not less than 1.5 cm; on the other hand, the size of mounting hole does not need too big under the condition of the demand that satisfies electric cooking machine emission steam, avoids extravagant exhaust piece's material firstly, prevents that the mounting hole is too big to lead to the heat preservation effect variation of culinary art process, therefore the diameter of mounting hole is not more than 2.5 cm.
7. Further, the pot cover also comprises a pot cover handle, and the distance from the center of the mounting hole to the center of the handle is 8-15 cm. In order to facilitate carrying of the pot cover, a pot cover handle is arranged on the pot cover, on one hand, in order that a user cannot be scalded by high-temperature water vapor discharged from the exhaust sheet when holding the handle, the distance between the mounting hole and the handle cannot be smaller than 8 cm; on the other hand, the position of the mounting hole (vent hole) is preferably as close as possible to the center of the lid, and particularly, when the lid handle is mounted right at the center of the lid, the position of the mounting hole (vent hole) is preferably as close as possible to the center of the handle, so that the water vapor in various positions in the pot is uniformly and rapidly discharged abroad, and the pressure in the pot is balanced, so that the distance between the mounting hole and the handle is not more than 15 cm.
8. Further, the exhaust part further comprises a fixing ring, the fixing ring comprises a side part, one end of the side part is connected with the exhaust sheet so that the exhaust sheet is fixed to the mounting hole, a flange is arranged at the other end of the side part and clamped on the lower surface of the periphery of the mounting hole, and therefore the exhaust part is mounted in the mounting hole. The fixing ring and the exhaust sheet can be integrally or separately molded, the side part is arranged on the fixing ring, one end of the fixing ring is connected with the exhaust sheet so that the exhaust piece is arranged on the upper surface of the periphery of the mounting hole, and the other end of the fixing ring forms a flange which is clamped on the lower surface of the periphery of the mounting hole, so that the exhaust piece can be conveniently fixed at the mounting hole; the exhaust piece is characterized in that the exhaust piece is provided with a fixing ring which is separated from the exhaust piece, the fixing ring is convenient to machine and form, the fixing ring is integrated with the exhaust piece, the assembling process is simple, the exhaust piece can be made of stainless steel materials, hard plastics or other metal materials can be adopted, the rigidity is high, the deformation is not easy, and the assembly is convenient.

In other embodiments, the junction 35 between the lateral surface 33 and the bottom 32 may be a sharp/right angle for simplicity of the process.
Advantageously, the lateral peripheral surface 33 comprises a lateral curved surface portion connected to the bottom portion 32, which is convex in a direction away from the water collecting recess 34. In this embodiment, all of the side circumferential surfaces 33 are side curved surface portions, and in other embodiments, the side curved surface portions may be a part of the side circumferential surfaces 33. The side curved surface part is beneficial to the water drops condensed on the side circumferential surface to flow back to the bottom along the curved surface.
Advantageously, the depth of said water trap recess 34 is between 1 and 5 mm. On one hand, when the depth of the water-gathering concave part is less than 1mm, the gathering effect on water drops is not obvious, and the problem that the water drops flow along the pot cover still occurs; on the other hand, when the depth of the water collecting concave part is more than 5mm, the water vapor overflows from the exhaust small holes and then passes through the water collecting concave part for a long depth, the contact area and the chance of the water vapor to the side peripheral surface are increased, so that the number of condensed water drops is increased, and the water vapor is not beneficial to the exhaust.
Advantageously, said degassing aperture 31 is provided in said bottom 32. On one hand, the water vapor discharged from the bottom exhaust small holes can contact the side circumferential surface as little as possible, so that the amount of condensed water is reduced; on the other hand, the process of forming the small exhaust holes in the bottom is simple, the assembly of the side circumferential surface and the mounting hole is not influenced, and meanwhile, the small exhaust holes are located at the intersection bottom of the water collecting concave part as far as possible, so that condensed water drops can conveniently flow back to the pot. In other embodiments, the vent holes 31 may also be extendably disposed at the connection 35, even on the side peripheral surface 33, in order to increase the area of the vent holes.

Here, the inner side refers to a side close to the center of the exhaust sheet 3, and the outer side refers to a side away from the center of the exhaust sheet 3. Therefore, after the bending part of the exhaust fin is assembled with the mounting hole, the exposed part is a continuous surface (the joint of the upper bending part and the lower bending part) rather than an end surface, so that the exhaust fin is attractive, and the exposed part is smooth and safe. By adopting the sealing ring, the water in the cooker can be prevented from overflowing from the assembly clearance between the bent part and the mounting hole and flowing along the surface of the cooker cover to cause the pollution of the cooker, and on the other hand, the extrusion of the bent part and the peripheral surface of the mounting hole can be buffered, so that the reliability of assembly is enhanced. In other embodiments, the lid may not include a sealing ring for cost and installation.
Advantageously, the exhaust member further comprises a stainless steel fixing ring 4, a first flange 41 is arranged at the top edge of the stainless steel fixing ring 4, a second flange 42 is arranged at the bottom of the fixing ring 4, the first flange 41 presses the lower bending portion 372 to the upper surface of the periphery of the mounting hole 11, and the second flange 42 is clamped on the lower surface of the periphery of the mounting hole 11, so that the stainless steel exhaust sheet 3 is mounted in the mounting hole 11. Through the split stainless steel fixing ring, the first flanging at the top of the stainless steel fixing ring is clamped with the lower bending part to the upper surface of the periphery of the mounting hole, and the second flanging at the bottom of the stainless steel fixing ring is clamped with the lower surface of the periphery of the mounting hole, so that the exhaust sheet can be conveniently fixed at the mounting hole; the fixing ring which is separated from the exhaust sheet is convenient to machine and form, and on the other hand, the exhaust sheet and the fixing ring which are separated are convenient to assemble due to the fact that stainless steel is high in rigidity and not prone to deformation.
Advantageously, the stainless steel fixing ring 4 comprises the side portion 43, one end of the side portion 43 extends to the lower side of the lid body 1 and forms the second flange 42, and the other end extends to form the first flange 41 above the outer surface of the lid body 1. So as to adapt to the depth of the mounting hole and enable the fixing ring to clamp the exhaust sheet.
Advantageously, an avoiding opening 373 through which the first turned edge 71 passes is formed between the inner side of the lower bent portion 372 and the side circumferential surface 33, and an accommodating space 374 for accommodating the first turned edge 41 is formed between the lower bent portion 372 and the upper bent portion 371. Therefore, the first flanging can extend into the upper part of the lower bending part, so that the exhaust sheet can be clamped by the fixing ring.
During installation, the exhaust sheet 3 and the fixed ring 4 are overlapped and fixed in an overlapping mode, the sealing ring 5 (such as a silica gel ring) is added below the exhaust sheet 3, the sealing ring passes through the installation hole 11 on the glass pot cover body 1, the fixed ring 4 is spun, and the fixed ring 4 is spun into a circle larger than 4/3, so that the exhaust sheet 3, the sealing ring 5 and the fixed ring 4 are fixed together.
Example 2:
the present embodiment 2 is different from the embodiment 1 in that, as shown in fig. 5, a reinforcing protrusion 362 is provided at a joint of adjacent reinforcing parts 36, and the reinforcing protrusion 362 protrudes toward the center of the exhaust sheet 3. The reinforcing protrusions may support the junction of adjacent reinforcing portions and advantageously reduce stress concentration at the junction.
Example 3:
the present embodiment 3 is different from the embodiment 1 in that, as shown in fig. 6, the vent sheet 3 is provided with a plurality of vent holes 31, and the plurality of vent holes 31 are spaced apart from each other. Therefore, the connecting parts are formed among the small exhaust holes, on one hand, the small exhaust holes ensure that the whole has enough exhaust capacity, steam is prevented from splashing out from a gap, meanwhile, the area of the single small exhaust hole is small, foreign matters are prevented from falling into the pot from the hole, on the other hand, the connecting parts also effectively enhance the overall strength of the exhaust sheet, and only one mounting hole needs to be formed in the pot cover, so that the manufacturing process is simple.
In this embodiment, the exhaust sheet 3 has 9 small exhaust holes, one of which is located at the center and the other 8 of which are uniformly distributed on the periphery of the center hole. Preferably, each of the vent apertures is circular and the same size. On the one hand, the processing is easy, and on the other hand, the exhaust is uniform. In other embodiments, the number, shape and arrangement position of the exhaust holes are not limited to those listed in the embodiment.
Example 4:
this embodiment 4 is different from embodiment 1 in that the side peripheral surface 33 includes side flat surface portions having an angle α of 90 ° or more and 135 ° or less with respect to the bottom portion 32 (not shown in the figure). Therefore, when in cooking, food in the pot is heated, and formed steam overflows from the small exhaust holes of the exhaust sheet, on one hand, the opening area of the upper part of the exhaust sheet is larger than or equal to the area of the bottom, so that the steam is favorably exhausted out of the pot body, and the chance of the steam contacting with the lateral periphery of the exhaust sheet is reduced; on the other hand, when a part of the water vapor is condensed on the side circumferential surface, the inclined side circumferential surface plays a role of guiding the backflow of the water droplets, and the water droplets are favorably flown back to the bottom along the inclined side plane portion.
Example 5:
the present embodiment 4 differs from embodiment 1 in that a seal ring is provided between the lower surface of the bent portion 37 and the upper surface of the outer periphery of the mounting hole, as shown in fig. 7. In the embodiment, the processing technology is simplified, and the cost is saved.
Preferably, in the present embodiment, the exhaust flap 3 of the exhaust member is integrally formed with the fixing ring. During installation, a sealing ring (such as a silica gel ring) is directly added below the exhaust piece and then penetrates through the installation hole in the glass pot cover body to spin the fixing ring part, and the fixing ring part is spun into a circle larger than 4/3, so that the exhaust piece sealing ring and the installation hole are fixed together. The assembly process of the exhaust sheet and the fixed ring is reduced.
