Detailed Description

The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.

Referring to the structure shown in fig. 1 and 2, a circular open cavity 2 for assembling a steam discharging device or placing a food steamer is formed on a cooking kitchen cover 1, a flange for placing the food steamer is formed on the open cavity 2, and a foam breaking structure is arranged in the open cavity 2.

In this technical scheme, owing to be formed with open cavity 2 on the culinary art kitchen utensils and appliances lid 1, and be provided with broken bubble structure in this open cavity 2 and can be used for placing the food steamer (as shown in fig. 2), like this, when needs use the food steamer, can place the food steamer on this open cavity 2, owing to the distance of culinary art kitchen utensils and appliances lid 1 and culinary art cavity is farther to the food steamer does not occupy the capacity of culinary art cavity, simultaneously, the steam bubble that carries in the steam will be broken when through broken bubble structure, thereby rice water in the culinary art cavity is difficult to overflow to the food material in the food steamer especially in great boiling section etc. in, the taste of food material in the food steamer has been promoted. When the steamer is used, the steamer can be removed, and the steam discharging device is assembled in the open cavity so as to discharge steam when steaming rice.

Further, in order to further utilize the steam in the cooking chamber to heat the steamer more comprehensively, preferably, the area of the open cavity 2 is set to be more than one fourth of the area of the cooking chamber, so that the area of the open cavity 2 can ensure that the large steamer is placed, and the steam in the cooking chamber can be utilized more fully.

Of course, in other alternatives, the area of the open cavity 2 may be the same as the area of the cooking chamber.

In the cooking utensil cover of the present invention, the bubble breaking structure may have various structures, for example, the entire bottom of the open cavity 2 may be opened and laterally provided with a bubble breaking net, or, as shown in fig. 1 to 3, the bubble breaking structure includes a bottom plate 4 formed in the open cavity 2 to be opposite to the cooking chamber and an opening 3 formed on the bottom plate 4. At this time, due to the blocking effect of the bottom plate 4, steam can only pass through the opening 3, that is, the opening 3 can allow high-temperature steam in the cooking cavity to pass through and enter the steamer, and meanwhile, when the steam bubbles carried in the high-temperature steam pass through the opening 3, the steam bubbles can be extruded and broken due to the space reduction, so that the steam bubbles are prevented from rising into the steamer.

In addition, referring to the structure shown in fig. 10, the bottom plate 4 may be formed with the openings 3 at a plurality of different positions, so that the plurality of openings 3 may facilitate steam to enter the open cavity 2 from different positions while breaking bubbles, so as to uniformly heat the steamer.

Further, referring to the structure shown in fig. 11, the plurality of openings 3 include a circular hole at the center of the bottom plate 4 and a plurality of other arc-shaped holes circumferentially spaced around the circular hole. In this way, it is easier for steam to enter the steamer uniformly for heating.

In addition, in a further subsidiary structure form of the bubble breaking structure, as shown in fig. 4, the soleplate 4 is formed with steam inlet housings 5 protruding toward the inside of the open cavity 2 at the opening 3, each steam inlet housing 5 forming a steam inlet cavity 6 located outside the open cavity and communicable with the cooking chamber, wherein steam inlet holes 7 are formed on the wall of the steam inlet housing 5.

In this way, since the soleplate 4 is preferably formed with the steam inlet housings 5 protruding toward the inside of the open cavity 2 at different positions, and each steam inlet housing 5 forms the steam inlet cavity 6 outside the open cavity 2, and the steam inlet holes 7 are formed on the wall of the steam inlet housing 5, for example, both the side wall and the top wall, in actual use, as shown by the arrows in fig. 4, steam in the cooking cavity will enter the steam inlet cavities 6 at different positions, and then enter the open cavity 2 from the steam inlet holes 7 on the wall of the steam inlet housing 5, thereby guaranteeing that steam in the cooking cavity enters the open cavity 2 over a large area while the steam inlet holes 7 break bubbles, so that steam is uniformly distributed in the open cavity 2, and thus food in the steamer can be uniformly heated. In addition, steam enters the other larger open cavity 2 from the larger steam inlet cavity 6 through the steam inlet holes 7 with suddenly changed apertures, so that the flow speed of the steam can be improved, and the heat is concentrated, thereby being more convenient for heating food materials in the steamer.

Of course, the opening 3 may be formed on the bottom plate 4, and then the opening of the steam inlet housing 5 is turned back toward the bottom plate 4 and connected to the bottom plate 4, or, as shown by a section line in fig. 4, for convenience of molding, it is preferable that the steam inlet housing 5 and the bottom plate 4 are integrally formed, for example, the bottom plate 4 including the steam inlet housing 5 may be integrally injection-molded.

In addition, the steam inlet holes 7 may be formed only on the side wall or the top wall of the steam inlet housing 5, but in order to make the steam more uniformly distributed, as shown in fig. 4 and 11, the steam inlet holes 7 are formed on both the top wall and the side wall of the steam inlet housing 5. Thus, as shown in fig. 11, steam in the steam inlet cavity 6 enters the open cavity 2 through the steam inlet holes 7 on the top wall and the side wall, and meanwhile, the steam inlet holes 7 on the side wall of the adjacent steam inlet shell 5 can enable opposite discharged air flows to touch each other to generate steam vortex, as shown by arc arrows in fig. 11, so that steam flows in the open cavity 2 and is distributed in the edge area of the open cavity 2 more easily.

Of course, the steam inlet holes 7 on the side wall of the steam inlet housing 5 may be holes arranged horizontally, or alternatively, as shown in fig. 4, the steam inlet holes 7 on the side wall of the steam inlet housing 5 extend obliquely upward, for example, the included angle between the axial direction and the horizontal direction of the steam inlet holes 7 is 30-45 °, or other suitable angle. In this way, the flow direction of steam can be guided, steam inlet holes 7 on the side walls of adjacent steam inlet shells 5 in the open cavity 2 can meet at a high speed in a specific direction to form steam vortex, and the distribution of steam in the open cavity 2 is more uniform as shown by arc arrows in fig. 11.

In addition, the aperture of the steam inlet 7 may be selected according to practical requirements, for example, the aperture of the steam inlet 7 is 4mm to 6mm, preferably 5mm, and of course, the aperture of the steam inlet 7 is not limited thereto, and may be 7 mm to 10mm, or may be 2mm, or may be of other suitable dimensions.

In addition, the steam inlet housings 5 at different positions on the floor panel 4 may have various arrangements, for example, may be arranged in rows and columns, such as two rows and two columns.

Alternatively, in order to form the vortex of the steam more easily, preferably, as shown in fig. 11, a circular steam inlet shell and a plurality of arc steam inlet shells which are circumferentially arranged at intervals are formed on the bottom plate 4, for example, as shown in fig. 11, a circular steam inlet shell is formed at the center, four arc steam inlet shells which are circumferentially arranged at equal intervals are uniformly distributed on the edge, so that the steam can enter the cavity from the cooking cavity more easily and uniformly under the vortex of the steam, and the heat loss is reduced.

In addition, in order to facilitate the rapid heating of the food materials in the steamer by using the steam in the cooking chamber more effectively, it is necessary that the steam in the cooking chamber passes through the steam inlet 7 as quickly as possible, and therefore, as shown in fig. 10, the plate area of the soleplate 4 is arranged to cover the cooking chamber, so that the steam in the middle and surrounding areas of the cooking chamber will pass through the steam inlet 7 effectively in time.

In addition, the present invention provides a cooking utensil cover assembly, as shown in fig. 1, 2 and 3, comprising a steam discharging device 8 and a steamer 9, and any one of the cooking utensil covers 1 described above, wherein the steam discharging device 8 and the steamer 9 can be selectively disposed in the open cavity 2, as shown in fig. 1-3. Of course, the steam discharging device 8 may have various structural forms, which will be described in detail below.

Thus, as described above, when the steam discharging device 8 is provided, the cooking utensil can be normally used to normally discharge high-temperature steam in the cooking chamber, when the food steamer 9 is placed, the distance between the cover body of the cooking utensil and the cooking chamber is long, and the food steamer 9 does not occupy the capacity of the cooking chamber, and meanwhile, the food in the food steamer is difficult to overflow into the food steamer 9 due to the foam breaking effect of the foam breaking structure, so that the taste of the food in the food steamer is improved.

Further, in order to more facilitate uniform dispersion of steam in the open cavity 2 for uniform heating of the basket 9, it is preferable that, as shown in fig. 2, when the open cavity 2 is formed with the bottom plate 4 for being opposite to the cooking cavity and having the opening 3, a space is provided between the bottom of the basket 9 placed in the open cavity 2 and the bottom plate 4 to form the steam diffusion cavity 10. In this way, the steam entering the open cavity 2 from the opening 3 will be evenly distributed in the steam diffusion cavity 10 to evenly heat the steamer 9, better than the buffering of the steam diffusion cavity 10.

As described above, in the cooking utensil cover assembly of the present invention, the steam discharging means 8 may have various configurations, for example, one configuration is shown in fig. 1 and 10, in which the steam discharging means 8 is a steam valve 11, so that the steam valve 11 is normally discharged when being assembled in the open cavity 2, and the steam valve 11 can be removed and placed on the open cavity 2 when the use of the food steamer is required.

Of course, in the case of the steam valve 11, it is sufficient if the open chamber 2 has a bottom plate 4, for example, when the bottom plate 4 is not provided, the entire bottom of the open chamber 2 may be formed with the openings 3 and provided with a foam breaking net, and the steam valves shown in fig. 1 and 10 may be provided in the open chamber 2. When the soleplate 4 is provided, a steam valve as shown in fig. 1 and 10 may also be provided, in which case the soleplate 4 and the opening 3 thereon may act as a bubble breaking structure.

One form of steam valve 11 is shown in fig. 1, and a positioning cylinder on the steam valve seat of the steam valve 11 can be assembled into the opening 3 in a sealing manner to serve as a steam inlet, and when the steamer needs to be placed, the steam valve 11 can be taken out from the opening cavity 2, as in switching between fig. 1 and 2.

Alternatively, as shown in fig. 10, in another structural form of the steam valve 11, steam inlet housings 5 protruding toward the inside of the steam valve are formed at different positions on a valve seat plate body 12 of a steam valve seat of the steam valve 11, each steam inlet housing 5 forming a steam inlet chamber 6 located outside the steam valve and capable of communicating with a cooking chamber, wherein steam inlet holes 7 are formed on walls of the steam inlet housing 5.

In this way, since the steam inlet housings 5 protruding toward the inside of the steam valve are formed at different positions of the valve seat plate body 12, and each steam inlet housing 5 forms the steam inlet cavity 6 outside the steam valve, and the steam inlet holes 7 are formed on the wall of the steam inlet housing 5, for example, the steam inlet holes 7 are formed on the side wall and the top wall, in actual use, as shown by the arrows in fig. 10, steam in the cooking cavity will enter the steam inlet cavities 6 at different positions, and then enter the inner cavity of the steam valve from the steam inlet holes 7 on the wall of the steam inlet housing 5, thereby ensuring that the steam in the cooking cavity passes through the steam valve seat in a large area, for example, steam can be uniformly distributed in the steam cavity of the steam valve, so that when the steam valve cover is provided, steam can be conveniently discharged, and when the steam valve cover is removed or the whole steam valve 11 is removed, and the steam cavity or the steam basket is placed in the position of the steam valve cover or the steam basket is placed in the steam cavity 2, the steam evenly distributed in the steam cavity or the steam cavity 2 can evenly heat the food material. In addition, when the steam valve cover is taken down and the steamer is placed at the position of the steam valve cover, steam enters another larger steam cavity from one larger steam cavity 6 through the steam inlet 7 with suddenly changed aperture, so that the flow speed of the steam can be improved, heat is concentrated, food materials in the steamer can be heated more conveniently, and the steam inlet 7 has a foam breaking effect.

Of course, an opening may be formed on the valve seat plate body 12, and then the opening of the intake housing 5 may be reversed toward the valve seat plate body 12 and connected to the valve seat plate body 12, or, as shown by a sectional line in fig. 10, for convenience of molding, it is preferable that the intake housing 5 and the valve seat plate body 12 are integrally formed, for example, the valve seat plate body 12 of the intake housing 5 may be integrally injection-molded.

In addition, the steam inlet holes 7 may be formed only on the side wall or the top wall of the steam inlet housing 5, but in order to make the steam more uniformly distributed, as shown in fig. 10 and 11, the steam inlet holes 7 are formed on both the top wall and the side wall of the steam inlet housing 5. Thus, as shown in fig. 10 and 11, steam in the steam inlet cavity 6 enters the steam cavity through the steam inlet holes 7 on the top wall and the side wall, and meanwhile, the steam inlet holes 7 on the side wall of the adjacent steam inlet shell 5 can enable opposite discharged air flows to touch each other to generate steam vortex, as shown by arc arrows in fig. 11, so that steam flows in the steam cavity and is distributed in the edge area of the steam cavity more easily.

Of course, the steam inlet holes in the top wall of the steam inlet housing 5 extend vertically, the steam inlet holes 7 in the side wall of the steam inlet housing 5 may be horizontally arranged holes, or alternatively, as shown in fig. 10, the steam inlet holes 7 in the side wall of the steam inlet housing 5 extend obliquely upward, for example, the angle between the axial direction and the horizontal direction of the steam inlet holes 7 is 30-45 °, or other suitable angle. In this way, the flow direction of steam can be guided, which is beneficial for the steam inlet holes 7 on the side wall of the adjacent steam inlet shell 5 in the steam cavity to meet at a high speed in a specific direction to form steam vortex, as shown by the arc arrow in fig. 11, so that the steam in the steam cavity is distributed more uniformly.

In addition, the intake housing 5 at different positions on the valve seat plate body 12 may have various arrangements, for example, may be arranged in rows and columns, such as two rows and two columns.

Still alternatively, in order to facilitate formation of a vortex of steam, it is preferable that a circular steam inlet housing and a plurality of arc steam inlet housings are formed on the valve seat plate body 12 at the center of the valve seat plate body as shown in fig. 11, for example, a circular steam inlet housing is formed at the center, four arc steam inlet housings are uniformly distributed at the edge at equal intervals in the circumferential direction as shown in fig. 11, so that a large area and uniform steam entering from the cooking chamber into the steam valve can be easily realized under the vortex of steam, and heat loss is reduced.

In addition, in order to facilitate the rapid heating of the food materials in the steamer by using the steam in the cooking chamber more effectively, it is required that the steam in the cooking chamber passes through the steam inlet 7 as quickly as possible, and therefore, as shown in fig. 10, the plate area of the valve seat plate body 12 is arranged to cover the cooking chamber, so that the steam in the middle and surrounding areas of the cooking chamber passes through the steam inlet 7 effectively in time.

Further, as shown in fig. 10, openings 3 corresponding to the steam inlet chambers 6 at different positions are formed on the bottom plate 4 of the cooking utensil cover 1, and positioning walls 13 surrounding the openings and engaged into the steam inlet chambers 6 are formed on the bottom plate 4. As shown in fig. 10, the valve seat plate body 12 is provided on the bottom plate 4, and the positioning wall 13 is fitted with the steam inlet chamber 6, so that stable and reliable positioning of the valve seat plate body 12 is achieved while exhausting.

The steam discharging device 8 is described in detail above as a structural form of the steam valve 11, and another structural form of the steam discharging device 8 will be described in detail below.

In this further construction, the steam discharging means 8 comprises a steam valve cover 14 and a soleplate 4, in particular, as shown in 3 non-used embodiments of fig. 3, 4 and 7-9, when the open cavity 2 is formed with the soleplate 4 for facing the cooking chamber and having the opening 3, the steam discharging means 8 comprises the steam valve cover 14 and the soleplate 4, wherein the steam valve cover 14 is capable of fitting within the open cavity 2 and forming a steam discharging channel with the soleplate 4, wherein the opening 3 is a steam inlet of the steam discharging channel.

Thus, the bottom plate 4 is used as a steam valve seat, so that the steam valve seat can be omitted, when the steam valve cover 14 is arranged, the cooking kitchen ware can normally discharge steam, and when the steamer is needed to be used, the steam valve cover 14 is taken down, and the steamer 9 is placed at the position of the steam valve cover 14.

Fig. 3 shows a structural form of the bottom plate 4, fig. 4 shows another structural form of the bottom plate 4, at this time, the steam valve cover 14 may be covered and clamped on the cooking kitchen cover 1, for example, in fig. 3, one end of the steam valve cover 14 is clamped with the cooking kitchen cover 1 through a buckle, and then the other end of the steam valve cover 14 is clamped with the cooking kitchen cover 1 through an elastic buckle, so as to realize the clamping fit of the steam valve cover 14.

Fig. 7 to 9 show another construction of the steam valve cover 14, as shown, a radially arranged multi-layered flange 16 is formed on the inner surface of a valve cover plate 15 of the steam valve cover 14, so that a steam discharge straight groove 17 and an inner steam discharge arc groove 18 and an outer steam discharge arc groove 19 which are sequentially communicated and radially outwardly arranged and circumferentially extend around the same center are formed on the inner surface of the valve cover plate 15, wherein a steam outlet 20 is formed on the valve cover plate 15 at the end of the outer steam discharge arc groove 19.

In this way, since the straight steam discharging groove 17, the inner steam discharging arc groove 18 and the outer steam discharging arc groove 19 which are radially and outwardly arranged are formed on the cover plate 15 of the valve cover, the inner steam discharging arc groove 18 and the outer steam discharging arc groove 19 form a plurality of layers of steam discharging arc grooves to prolong the steam flow passage, and meanwhile, because of the arc wall surfaces on the two sides of the arc grooves, steam bubbles carried by steam are continuously collided on the arc wall surfaces to be crashed while flowing along the arc grooves, thereby being capable of effectively preventing overflow. Meanwhile, the steam box 9 can be placed after the steam valve cover 14 is removed.

Of course, the inner steam discharge arc groove 18 and the outer steam discharge arc groove 19 may extend circumferentially only at one side of the steam discharge straight groove 17 and have the same center.

Alternatively, in order to avoid the concentrated flow of the hot steam, reduce the flow noise, and further enhance the anti-overflow effect, it is preferable that the steam flowing out of the steam discharging straight groove 17 needs to be branched so as to weaken the steam amount in the inner steam discharging arc groove 18 and the outer steam discharging arc groove 19 on one side, and therefore, as the structure shown in fig. 9, both sides of the steam discharging straight groove 17 are formed with the inner steam discharging arc groove 18 and the outer steam discharging arc groove 19 symmetrically arranged with respect to the steam discharging straight groove, and both sides of the outer steam discharging arc groove 19 communicate with the steam outlet 20. In this way, at the junction of the straight steam discharge groove 17 and the two inner steam discharge arc grooves 18, steam will be split into the inner steam discharge arc grooves 18 and the outer steam discharge arc grooves 19 on both sides of the straight steam discharge groove 17, so that the steam quantity is weakened and the flow noise is reduced accordingly.

Of course, in order to enhance the bubble breaking effect, as shown in fig. 9, an expansion groove 21 is formed at the end of the straight steam discharge groove 17, and the expansion groove 21 and the inner steam discharge arc groove 18 are communicated, so that a part of the steam bubbles enter the expansion groove 21 from the straight steam discharge groove 17 and are automatically broken due to the change of the space pressure.

Finally, in order to further enhance the anti-overflow effect, the steam valve cover 14 of the present invention needs to cool the flowing hot steam, so that, as shown in fig. 9, a cool air storage groove 23 is formed between the outer flange 16 and the valve cover sidewall 22, and an opening 24 of the cool air storage groove 23 is formed in the valve cover sidewall 22. In this way, in use, the temperature in the cold air reservoir 23 will be the same as the outside temperature, to the extent that it will cool the flowing hot steam, so that part of the hot steam condenses to form running water.

In addition, as shown in fig. 7 and 8, a seal ring 27 such as a silica gel member is fitted in an annular groove on the outer peripheral surface of the valve cover side wall 22, and an annular bead is radially outwardly projected on the outer peripheral surface of the seal ring 27, the annular bead being pressed between the valve cover side wall 22 and the inner peripheral surface of the open chamber 2. In this way, the ring-shaped groove can prevent the sealing ring 27 from falling off when the steam valve cover 14 is replaced, and meanwhile, because the annular convex rib is extruded and deformed, an interference fit is formed between the valve cover side wall 22 and the inner peripheral surface of the open cavity 2, so that the steam valve cover 14 can be stably and reliably fixed in the open cavity 2, and the problem that the steam valve cover 14 jumps due to steam force is avoided.

Finally, the present invention provides a cooking utensil comprising a cooking utensil cover assembly as described above, as shown in fig. 5 and 6, wherein the cooking utensil cover 1 is assembled to a cooking utensil body 25.
