Description

Technical Field

[0001] The present application belongs to the technical field of cooking utensils, and specifically relates to an anti-overflow cooking utensil. Background Art

[0002] When cooking in an electric rice cooker, a large amount of steam is generated in the cooking chamber as cooking progresses. The steam is discharged through the exhaust port of the steam valve located on the lid. When cooking rice porridge or other dishes, a large number of bubbles are generated during the cooking process. If the cooking power is too high or continuous cooking is used, the bubbles containing rice soup will overflow from the exhaust port, which will not only cause cleaning problems for the user, but also cause the rice soup in the exhaust port to solidify if the steam valve is not cleaned in time, making cleaning more difficult and clogging the exhaust port, making it impossible to vent. If low-power heating is used to reduce the heating power, the cooking time will be longer, affecting the user experience.

[0003] The prior art discloses a steam valve, which includes a valve seat with an air inlet and a valve cover with an air outlet, and also includes an independently formed intermediate cover plate, which spans between the valve seat and the valve cover to separate the steam valve into two steam chambers from bottom to top. Specifically, the intermediate cover plate is connected to the valve cover to form an upper steam chamber, and the intermediate cover plate is connected to the valve seat to form a lower steam chamber. An intermediate air vent connecting the upper steam chamber and the lower steam chamber is provided on the intermediate cover plate. The steam entering from the air inlet passes through the lower steam chamber, the upper steam chamber and the air outlet in sequence and is discharged from the steam valve. The steam valve separates the space between the valve seat and the valve cover by the intermediate cover plate provided between the valve seat and the valve cover, so as to improve the bubble breaking ability and overflow prevention performance by extending the steam flow path. The steam valve has the following defects: in order to avoid steam leakage between the independently formed middle cover plate and the valve seat, or between the middle cover plate and the valve cover, it is necessary to add a strict sealing design between the three, which increases the sealing cost; the steam chamber is arranged in an upper and lower manner, and the upper steam chamber and the lower steam chamber are connected through the vent hole on the middle cover plate. The vent hole can form a steam connection channel, but the condensed water after the steam condenses in the upper steam chamber is difficult to flow back from the vent hole to the lower steam chamber, and when the pot cover is pivoted open, the condensed water tends to flow to one side of the upper steam chamber and continue to exist, causing the upper steam chamber to be in a humid environment for a long time, thereby causing the growth of bacteria, and when too much condensed water accumulates in the upper steam chamber, it will block the vent hole, thereby affecting the discharge of steam; the valve cover, the middle cover plate and the valve seat are arranged in sequence from top to bottom, in order to respectively realize the connection between the middle cover plate and the valve seat and the valve cover. The installation and fixation of the steam valve inevitably requires the addition of a structure for achieving the installation and fixation, which increases the height of the steam valve and further increases the thickness of the pot cover, which not only increases the production cost, but also makes the entire pot cover appear thick and heavy, which is not conducive to its lightness and thinness; the steam is discharged from the air outlet after passing through the air inlet, the lower steam chamber and the upper steam chamber. The steam flow path is horizontal in most states. In high-power cooking mode, the material that flows up into the steam valve includes not only steam but also solid matter such as rice soup. The gravity of such materials, including the gravity of the steam itself, will hinder the flow of steam. When the steam flow path is horizontal in most states, the flow resistance of horizontal flow is greater than the flow resistance of vertical flow, which leads to reduced exhaust efficiency. The steam in the cooking chamber cannot be discharged in time, and the overflow phenomenon is aggravated. Utility Model Content

[0012] The steam outlets are distributed at equal angles around the steam inlet pipe.

[0013] The retaining ribs extend in a winding manner along an axial cross section of the valve cavity and / or along a radial cross section of the valve cavity, so as to form winding drainage channels in the steam inlet cavity and the steam outlet cavity.

[0014] The steam valve assembly also includes a valve body provided with the steam inlet pipe, the valve body and the valve cover cooperate to form the valve cavity, the valve body is provided with a reflux hole and a reflux valve, the reflux valve is movably provided on the valve body to open or cover the reflux hole; the pot cover includes an inner cover, the inner cover is provided with a through opening for the reflux valve to move; or, the pot cover includes an inner cover, the steam inlet pipe is installed on the inner cover, the valve cover or the inner cover is provided with a sealing member, the valve cover, the sealing member and the inner cover cooperate to form the valve cavity, the inner cover is provided with a reflux hole and a reflux valve, the reflux valve is movably provided on the inner cover to open or close the reflux hole.

[0015] The valve body or the inner cover is provided with a reflux groove which is recessed downwards to collect liquid, the reflux hole is communicated with the reflux groove, and at least a part of the reflux groove is located in the steam outlet cavity.

[0016] The pot cover includes a lining cover and an inner cover detachably mounted on the lining cover, the steam valve assembly is mounted on the inner cover, a partial area of ​​the lining cover protrudes upward to form a concave cavity for accommodating the steam valve assembly, and the lining cover is provided with a steam exhaust port corresponding one-to-one to the steam outlet.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0019] 1. In the present application, a retaining rib is provided in the valve cavity, and the retaining rib can separate the space in the valve cavity so as to separate it into a steam inlet cavity and a steam outlet cavity, and the steam outlet end of the steam inlet pipe is located in the steam inlet cavity, so that the steam entering the valve cavity from the steam inlet end of the steam inlet pipe can enter the multiple steam outlet cavities through the separation and blocking of the retaining rib, thereby effectively extending the flow path of the steam in the limited valve cavity space, not only improving the bubble breaking ability and thus improving the anti-overflow effect, so that even if high-power cooking is used during the cooking process, there will be no continuous bubble overflow from the exhaust port of the steam valve assembly, but also helping to improve the condensation effect, reduce the temperature of the steam when it is discharged from the steam outlet, avoid high-temperature steam from damaging the panel and other structural parts located around the steam outlet of the pot cover connected to the steam outlet, and extend the service life of the panel.

[0020] Furthermore, the arrangement of multiple steam outlets in this application helps improve steam exhaust efficiency, avoiding the more serious problem of overflowing caused by increased pressure in the cooking chamber of the cooking appliance due to untimely steam exhaust. Multiple steam outlets can also disperse the steam exhaust pressure and reduce exhaust noise.

[0021] In addition, the valve cavity is divided into a steam inlet cavity and a steam outlet cavity due to the presence of the retaining ribs. The steam outlet end of the steam inlet pipe is located in the steam inlet cavity. Therefore, the steam entering the valve cavity needs to pass through a specific flow path before being discharged, which can help form a micro-pressure environment in the cooking cavity to achieve a micro-pressure cooking effect.

[0022] 2. As a preferred embodiment of the present application, a retaining rib is provided on the valve cover, and a first flow gap connecting the steam inlet chamber and the steam outlet chamber is present between the bottom end of the retaining rib and the bottom wall of the valve chamber. The existence of the first flow gap not only provides a channel for steam to flow from the steam inlet chamber to the steam outlet chamber, but also provides a channel for the collection and backflow of condensed water. That is, no matter whether the setting position of the reflux hole corresponds to the steam inlet chamber or the steam outlet chamber, due to the existence of the first flow gap, the condensed water in the steam inlet chamber or the steam outlet chamber that is not arranged corresponding to the reflux hole will converge to the reflux hole through the first flow gap to realize reflux, thereby avoiding the problems of obstruction of steam flow, bacterial growth and the inability of condensed water in the steam inlet chamber or the steam outlet chamber to reflux.

[0023] In addition, the steam outlet end of the steam inlet pipe extends upward to extend into the upper area of ​​the steam inlet cavity, and a first flow gap exists between the bottom end of the retaining rib and the bottom wall of the valve cavity. After the steam flows upward and is discharged from the steam outlet end, part of the steam flows downward to pass through the first flow gap and flow to the steam outlet cavity, thereby extending the flow path of the steam and helping to improve the bubble breaking effect and overflow prevention effect.

[0024] 3. As a preferred embodiment of the present application, a second flow gap is provided between the retaining rib and the inner side wall of the valve cavity, connecting the steam inlet cavity and the steam outlet cavity. This allows the steam cavity to flow along the retaining rib toward the inner side wall of the valve cavity after being discharged from the steam outlet end of the steam inlet pipe, and to flow to the steam outlet cavity through the second flow gap, thereby extending the steam flow path and helping to improve the bubble breaking and overflow prevention effects. By rationally arranging the distance between the steam outlet end of the steam inlet pipe and the steam outlet of the valve cover relative to the second flow gap, the steam flow path can be further extended, and the resistance loss along the steam path can be increased, thereby improving the condensation effect while facilitating bubble breaking.

[0025] 4. As a preferred embodiment of the present application, there are multiple retaining ribs to separate the valve cavity into a steam inlet cavity and multiple steam outlet cavities arranged around the steam inlet cavity. There is a flow opening between two adjacent retaining ribs, and one steam outlet cavity corresponds to one steam outlet. The design of multiple steam outlet cavities, multiple flow openings, and multiple steam outlets can provide steam with multiple discharge paths, thereby improving the steam discharge efficiency. Multiple discharge paths can disperse the discharge pressure of the steam, reduce the exhaust pressure of a single steam outlet, and reduce the probability of splashing. Moreover, by providing multiple retaining ribs to form multiple steam outlet cavities, the limited space of the valve cavity can be fully utilized to extend the steam flow path, and the pressure can be changed by diversion. The change in pressure will cause the surface tension of the bubbles to change, which is conducive to bubble breaking and thus improves the anti-overflow effect.

[0026] 5. As a preferred embodiment of the present application, the retaining ribs extend in a winding manner along the axial cross-section of the valve cavity and / or along the radial cross-section of the valve cavity, so as to form a winding drainage channel in the steam inlet cavity and the steam outlet cavity. The design of the winding drainage channel can not only extend the flow path of the steam and slow down the flow rate of the steam, thereby reducing the impact of the steam on the steam outlet and reducing noise, but also because the flow path is extended, the contact time of the steam with the retaining ribs, the inner side wall of the valve cavity, etc. can be extended, which helps to increase the contact time of the steam with the retaining ribs, the inner side wall of the valve cavity, etc., improve the heat exchange efficiency, and thus help to improve the condensation effect. In addition, the retaining ribs extend in a winding manner, making full use of the limited space in the valve cavity, realizing the extension of the steam flow path, and helping to miniaturize the steam valve assembly, thereby helping to achieve a lightweight design of the pot cover.

[0027] 6. As a preferred embodiment of the present application, the pot lid includes a lining cover and an inner cover detachably mounted on the lining cover, the steam valve assembly is mounted on the inner cover, a portion of the lining cover protrudes upward to form a concave cavity for accommodating the steam valve assembly, and the lining cover is provided with a steam exhaust port corresponding one-to-one to the steam outlet. The provision of the concave cavity, on the one hand, makes full use of the redundant space inside the pot lid to accommodate the steam valve assembly, thereby helping to reduce the overall thickness of the pot lid and achieve a lightweight design of the pot lid. On the other hand, the steam valve assembly is mounted on the inner cover, and the inner cover is detachably mounted on the lining cover, so that the user can disassemble the inner cover for thorough cleaning. The presence of the concave cavity can serve as an explicit reminder to the user during the process of reassembling the inner cover to the lining cover, as well as a rough positioning function for the inner cover assembly, thereby improving the assembly efficiency of the inner cover and enhancing the user experience.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0062] Example 1:

[0063] like Figure 1 and Figure 2 As shown, an anti-overflow cooking utensil includes a pot body with a cooking cavity and a pot lid for opening or closing the pot body, the pot lid is provided with a steam valve assembly, the steam valve assembly includes a valve cavity, a steam inlet pipe 21 and a valve cover 1, a retaining rib 120 is provided in the valve cavity, the retaining rib 120 separates the valve cavity into a steam inlet cavity 11 and a steam outlet cavity 12 that are interconnected, the valve cover 1 is provided with a plurality of steam outlets 110 that are connected to the steam outlet cavity 12, the steam outlet end of the steam inlet pipe 21 is located in the steam inlet cavity 11, and the steam entering the steam inlet cavity 11 is blocked by the retaining rib 120 from entering the plurality of steam outlet cavities 12.

[0064] The valve cavity in this embodiment is provided with a retaining rib 120, which can separate the space in the valve cavity so as to divide it into a steam inlet cavity 11 and a steam outlet cavity 12, and the steam outlet end of the steam inlet pipe 21 is located in the steam inlet cavity 11, so that the steam entering the valve cavity from the steam inlet end of the steam inlet pipe 21 can be discharged in sequence through the steam inlet cavity 11, the steam outlet cavity 12 and the steam outlet 110, thereby effectively extending the flow path of the steam in the limited valve cavity space, not only improving the bubble breaking ability and thus improving the anti-overflow effect, so that even if high-power cooking is used during the cooking process, there will be no continuous bubble overflow from the exhaust port 42 of the steam valve assembly, but also helping to improve the condensation effect, reduce the temperature of the steam when it is discharged from the steam outlet 110, avoid high-temperature steam from damaging the panel and other structural parts located around the steam outlet 42 of the pot cover connected to the steam outlet 110, and extend the service life of the panel.

[0065] Furthermore, the arrangement of multiple steam outlets 110 in this embodiment improves steam exhaust efficiency, preventing the problem of overcooking caused by increased pressure in the cooking chamber of the cooking appliance due to untimely steam exhaust. Furthermore, multiple steam outlets 110 can disperse the steam exhaust pressure and reduce exhaust noise.

[0066] In addition, the valve cavity is divided into a steam inlet cavity 11 and a steam outlet cavity 12 due to the presence of the retaining rib 120. The steam outlet end of the steam inlet pipe 21 is located in the steam inlet cavity 11. Therefore, the steam entering the valve cavity needs to pass through a specific flow path before being discharged, which can help to form a micro-pressure environment in the cooking cavity to achieve a micro-pressure cooking effect.

[0067] This embodiment does not limit the location of the retaining rib. In one embodiment, the retaining rib 120 is provided on the valve cover 1, and preferably, the retaining rib 120 and the valve cover 1 are integrally formed. In another embodiment, the retaining rib 120 is provided on the valve body 2 and extends upward, with a gap between the top of the retaining rib 120 and the valve cover 1 for steam circulation. In yet another embodiment, the retaining rib 120 is provided on the inner cover 3 and extends upward, with a gap between the top of the retaining rib 120 and the valve cover 1 for steam circulation.

[0068] In this embodiment, the steam inlet cavity 11 and the steam outlet cavity 12 can be connected in any of the following ways:

[0069] Implementation method 1: Figure 2 As shown, the retaining rib 120 is provided on the valve cover 1, and a first flow gap 7 is provided between the bottom end of the retaining rib 120 and the bottom wall of the valve cavity, connecting the steam inlet cavity 11 and the steam outlet cavity 12. A flow channel 9 for steam flow is provided between the outer wall of the steam inlet pipe 21 and the retaining rib 120. The existence of the first flow gap 7 and the flow channel 9 not only provides a channel for steam to flow from the steam inlet cavity 11 to the steam outlet cavity 12, but also provides a channel for the collection and backflow of condensed water. That is, regardless of whether the setting position of the reflux hole 23 corresponds to the steam inlet cavity 11 or the steam outlet cavity 12, due to the existence of the first flow gap 7, the condensed water in the steam inlet cavity 11 or the steam outlet cavity 12 that is not arranged corresponding to the reflux hole 23 will converge to the reflux hole 23 through the first flow gap 7 to achieve backflow, thereby avoiding the problems of obstruction of steam flow and bacterial growth caused by the inability of condensed water in the steam inlet cavity 11 or the steam outlet cavity 12 to backflow.

[0070] In addition, the steam outlet end of the steam inlet pipe 21 extends upward to extend into the upper area of ​​the steam inlet cavity 11, and the first flow gap 7 exists between the bottom end of the retaining rib 120 and the bottom wall of the valve cavity. After the steam flows upward and is discharged from the steam outlet end, part of the steam flows downward to pass through the first flow gap 7 and flow to the steam outlet cavity 12, thereby extending the flow path of the steam, which helps to improve the bubble breaking effect and overflow prevention effect.

[0071] Implementation method 2: Figure 4As shown, there is a second flow gap 8 between the retaining rib 120 and the inner wall of the valve cavity, connecting the steam inlet cavity 11 and the steam outlet cavity 12. The presence of the second flow gap 8 enables the steam cavity to flow along the retaining rib 120 toward the inner wall of the valve cavity after being discharged from the steam outlet end of the steam inlet pipe 21, so as to flow to the steam outlet cavity 12 through the second flow gap 8, thereby extending the flow path of the steam and helping to improve the bubble breaking effect and overflow prevention effect. By rationally arranging the distance between the steam outlet end of the steam inlet pipe 21 and the steam outlet 110 of the valve cover 1 relative to the second flow gap 8, the flow path of the steam can be further extended, and the resistance loss along the steam path can be increased, thereby improving its condensation effect while facilitating its bubble breaking.

[0072] Embodiment 3: A first flow gap 7 connects the steam inlet chamber 11 and the steam outlet chamber 12 between the bottom end of the retaining rib 120 and the bottom wall of the valve chamber. A flow channel 9 for steam flow exists between the outer wall of the steam inlet pipe 21 and the retaining rib 120. A second flow gap 8 connects the steam inlet chamber 11 and the steam outlet chamber 12 between the retaining rib 120 and the inner wall of the valve chamber. This arrangement improves steam exhaust efficiency and extends the steam flow path, enhancing bubble breaking and condensation.

[0073] This embodiment does not limit the number of the retaining ribs 120 and the number of the steam outlets 110, and any of the following embodiments may be adopted:

[0074] Implementation method 4: Figure 10 As shown, there is one barrier rib 120, with a flow opening 10 between the head and tail ends of the barrier rib 120. A portion of the steam entering the steam inlet chamber 11 from the steam inlet pipe 21 flows along the sidewall of the barrier rib 120 facing the steam inlet pipe 21 toward the head and tail ends of the barrier rib 120, and enters the steam outlet chamber 12 through the flow opening 10 between the head and tail ends. The steam outlet chamber 12 is arranged around the steam inlet chamber 11, and there can be two, three, or even more steam outlets 110.

[0075] Embodiment 5: There are multiple retaining ribs 120 to separate the valve cavity into a steam inlet cavity 11 and multiple steam outlet cavities 12 arranged around the steam inlet cavity 11 , and there is a flow opening 10 between two adjacent retaining ribs 120 .

[0076] In one example, if Figure 7As shown, in this example, there are two retaining ribs 120, which extend downward from the valve cover 1 to separate the valve cavity into a steam inlet cavity 11 and two steam outlet cavities 12. There are two steam outlets 110, and one steam outlet cavity 12 is connected to one steam outlet 110, where the direction of the arrow indicates the flow direction of the steam. Each rib 120 has two ends, and there is a second flow gap 8 between the two ends and the inner wall side of the valve cavity. Part of the steam entering the steam inlet cavity 11 from the steam inlet pipe 21 flows along the side wall of the rib 120 facing the steam inlet pipe 21 to the two ends of the rib 120, and is diverted at the flow port 10 between the two adjacent ends of the two ribs 120 to enter the two steam outlet cavities 12 respectively. The steam undergoes multiple diversions and turns during the entire flow process. On the one hand, the pressure change brought about by the diversion helps to achieve bubble breaking and also helps to achieve flow rate adjustment. On the other hand, the diversion and diversion help to extend the flow path of the steam in the limited space of the valve cavity, thereby further achieving bubble breaking and overflow prevention, and is beneficial to the condensation of steam.

[0077] In another example, Figure 8 As shown, in this example, there are three retaining ribs 120, which extend downward from the valve cover 1 to separate the valve cavity into a steam inlet cavity 11 and three steam outlet cavities 12. There are three steam outlets 110, and one steam outlet cavity 12 is connected to one steam outlet 110, where the direction of the arrow indicates the flow direction of the steam.

[0078] In another example, Figure 9 As shown, in this example, there are four retaining ribs 120, and the four retaining ribs 120 extend downward from the valve cover 1 to separate the valve cavity into a steam inlet cavity 11 and four steam outlet cavities 12. There are four steam outlets 110, and one steam outlet cavity 12 is connected to one steam outlet 110, where the direction of the arrow indicates the flow direction of the steam.

[0079] As a preferred example under the fifth embodiment, the steam outlets 110 are distributed at equal angles around the steam inlet pipe 21, thereby helping to achieve uniform gas outlet at each steam outlet 110 and avoiding excessive steam outlet and high steam outlet pressure at a single steam outlet 110, which may adversely affect the parts of the pot cover adjacent to the steam outlet 110 by the influence of high temperature and high humidity steam.

[0080] In this embodiment, the structural shape of the retaining rib 120 can adopt any one of the following embodiments:

[0081] Embodiment 6: The cross section of the retaining rib 120 along the axial direction of the valve cavity and / or the cross section of the retaining rib 120 along the radial direction of the valve cavity are both straight lines.

[0082] Implementation method seven: Figure 5As shown, the retaining rib 120 extends in a winding manner along the axial cross-section of the valve cavity and / or the radial cross-section of the retaining rib 120 of the valve cavity, so as to form a winding drainage channel in the steam inlet cavity 11 and the steam outlet cavity 12. The winding extension can be, for example, a wave-like extension, or an irregular curve-like extension. The design of the winding drainage channel can not only extend the flow path of the steam and slow down the flow rate of the steam, thereby reducing the impact of the steam on the steam outlet 110 and reducing noise, but also because the flow path is extended, the contact time of the steam with the retaining rib 120, the inner side wall of the valve cavity, etc. can be longer, which helps to increase the contact time of the steam with the retaining rib 120, the inner side wall of the valve cavity, etc., improve the heat exchange efficiency, and thus help to improve the condensation effect. In addition, the retaining rib 120 extends in a winding manner, making full use of the limited space in the valve cavity, realizing the extension of the steam flow path, and helping to miniaturize the steam valve assembly, thereby helping to achieve a lightweight design of the pot cover.

[0083] like Figure 1 As shown, the steam valve assembly in this embodiment further includes a valve body 2 provided with a steam inlet pipe 21 , and the valve body 2 and the valve cover 1 cooperate to form a valve cavity.

[0084] As a preferred implementation method under this embodiment, Figure 3 and Figure 4 As shown, the valve body 2 is provided with a reflux hole 23 and a reflux valve 24. The reflux valve 24 is movably mounted on the valve body 2 to open and close the reflux hole 23. The pot lid includes an inner cover 3, which has an opening through which the reflux valve 24 can move. When the pressure in the cooking chamber rises to a certain threshold, the reflux valve 24 is pushed upward to close the reflux hole 23, preventing steam from flowing back into the valve chamber. When the pressure in the cooking chamber drops to a certain threshold, the reflux valve 24 descends due to its own weight and the weight of the liquid in the valve chamber, opening the reflux hole 23. The accumulated liquid in the valve chamber then flows back into the cooking chamber through the reflux hole 23.

[0085] Preferably, the valve body 2 is provided with a downwardly recessed reflux groove 22 for collecting liquid, and the reflux hole 23 is connected to the reflux groove 22. At least a portion of the reflux groove 22 is located within the steam outlet chamber 12. The reflux groove 22 is formed by a downwardly recessed portion of the valve body 2, facilitating the collection of condensed water and liquid that falls back after bubbles break in the valve cavity, allowing the liquid to flow back through the reflux hole 23 connected to the reflux groove 22. Furthermore, the bottom wall of the valve body 2 is provided with a guiding slope, and the liquid inlet end of the reflux groove 22 is located at the lower position of the guiding slope to facilitate the collection of condensed water.

[0086] The specific setting position of the reflux groove 22 is not limited: in one example, the projection of the steam outlet chamber 12 onto the bottom wall of the valve body 2 covers the reflux groove 22, that is, the reflux groove 22 is located in the steam outlet chamber 12; in another example, the projection of the steam outlet chamber 12 onto the bottom wall of the valve body 2 covers a part of the reflux groove 22, and the projection of the steam inlet chamber 11 onto the bottom wall of the valve body 2 covers another part of the reflux groove 22, that is, part of the reflux groove 22 is located in the steam outlet chamber 12 and part of the reflux groove 22 is located in the steam inlet chamber 11.

[0087] In a specific example, Figure 4 and Figure 6 As shown, the reflux groove 22 is arranged adjacent to the steam inlet pipe 21, and a portion of the outer wall of the steam inlet pipe 21 constitutes a portion of the inner wall of the reflux groove 22. On the one hand, it is convenient for the forming of the reflux groove 22 and the steam inlet pipe 21 during the manufacturing process, and on the other hand, it is convenient for the reflux groove 22 to collect condensed water flowing downstream from the outer wall of the steam inlet pipe 21.

[0088] As a preferred implementation method under this embodiment, Figure 1 and Figure 11 As shown, the pot cover includes a lining cover 4 and an inner cover 3 detachably mounted on the lining cover 4, and the steam valve assembly is mounted on the inner cover 3, as shown in FIG. Figures 12 to 14 As shown, a portion of the lining cover 4 protrudes upward to form a recessed cavity 41 for accommodating the steam valve assembly. The lining cover 4 is provided with a steam exhaust port 42 corresponding one-to-one with the steam outlet 110. The inner cover 3 is detachably mounted on the lining cover 4, and the steam valve assembly is mounted on the inner cover 3. This allows the steam valve assembly to be removed from the lining cover 4 along with the inner cover 3, making it convenient for the user to thoroughly clean the inner cover 3 and the steam valve assembly and avoid the accumulation of dirt. In this embodiment, the provision of the recessed cavity 41 on the lining cover 4, on the one hand, fully utilizes the redundant space inside the pot lid to accommodate the steam valve assembly, thereby helping to reduce the overall thickness of the pot lid and achieve a lightweight and thin pot lid design. On the other hand, the steam valve assembly is mounted on the inner cover 3, and the inner cover 3 is detachably mounted on the lining cover 4, making it easy for the user to remove the inner cover 3 for thorough cleaning. The presence of the recessed cavity 41 serves as a clear reminder to the user during the reassembly of the inner cover 3 to the lining cover 4, and also serves as a rough positioning function for the inner cover 3 assembly, thereby improving the assembly efficiency of the inner cover 3 and enhancing the user experience.

[0089] Preferably, if Figure 2 As shown, a second sealing member 6 is provided between the steam outlet 110 of the valve cover 1 and the steam exhaust port 42 of the liner cover 4 to prevent steam from leaking from the matching position of the valve cover 1 and the liner cover 4 .

[0090] In this embodiment, the steam valve assembly includes a detachably connected valve body 2 and valve cover 1. The detachable valve body 2 and valve cover 1 facilitate the user's removal of both for thorough cleaning of the inner wall of the valve cavity. The detachable connection between the valve body 2 and valve cover 1 can be achieved by screw connection, snap connection, threaded connection, magnetic connection, etc.

[0091] Example 2:

[0092] The structure and principle of the present embodiment 2 are basically the same as those of the embodiment 1. The difference is that compared with the valve body 2 in the embodiment 1, the present embodiment 2 does not have a valve body 2. The details are as follows:

[0093] like Figure 15 As shown, in this embodiment 2, the steam inlet pipe 21 is mounted on the inner cover 3. The valve cover 1 or the inner cover 3 is provided with a first sealing member 5. The valve cover 1, the first sealing member 5, and the inner cover 3 cooperate to form a valve chamber. The inner cover 3 is provided with a reflux hole and a reflux valve. The reflux valve is movably mounted on the inner cover 3 to open or close the reflux hole. This embodiment 2 eliminates the need for a valve body, which not only saves processing and manufacturing costs but also reduces the thickness of the pot lid to a certain extent. Furthermore, the valve cover 1 is mounted on the lining cover 4, and the steam inlet pipe 21 is mounted on the inner cover 3. When the inner cover 3 is removed from the lining cover 4, the inner sidewalls of the valve cover 1 and the inner sidewalls of the first sealing member 5 are fully exposed to the user, making them easier to clean. Compared to embodiment 1, this eliminates the need to separately disassemble the valve cover 1 and valve body 2 to clean their inner sidewalls, reducing the burden on the user.

[0094] In this second embodiment, to facilitate the return of condensed water, the inner cover 3 is provided with a downwardly recessed reflux groove for collecting liquid. The reflux hole is connected to the reflux groove, and at least a portion of the reflux groove is located within the steam outlet chamber 12. This arrangement can reduce the amount of condensed water accumulated in the steam outlet chamber 12, prevent condensed water from overflowing from the steam outlet 110, and reduce the adverse effects of condensed water accumulation on the flow and discharge of steam.

[0095] As a preferred implementation of this embodiment 2, Figures 12 to 14 As shown, part of the lining cover 4 protrudes upward to form a cavity 41 for accommodating the valve cover 1 and the first sealing member 5. In this way, the redundant space in the pot cover can be fully utilized to arrange the valve cover 1 and the first sealing member 5, which helps to make the pot cover lighter and thinner.

[0096] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0097] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0098] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
