Technical field

The present invention relates to the field of kitchen utensils and, more particularly, relates to a steam valve and a cooking apparatus comprising a steam valve.

State of the art

Currently, cookers on the market, such as a rice cooker, typically use a blocking rib to block the steam to lock the steam valve on the lid or seat of the steam valve to enhance the anti-spill effect of the steam valve; however, rice broth clumps and the like formed during the preparation of rice may adhere to the dead zone formed between the blocking rib and the valve seat, and to the dead zone formed between the blocking rib and the valve cover, leading to difficult or incomplete cleaning and other problems that affect on the effect of using the product and on the user experience.

Disclosure of the invention

The present invention is directed to solving at least one of the technical problems of the prior art.

To this end, in one aspect of the present invention, a steam valve is provided.

In another aspect of the present invention, there is provided a cooking apparatus comprising the aforementioned steam valve.

To achieve the above objectives, according to an embodiment of one aspect of the present invention, the steam valve comprises: a valve seat; a valve cover, which is formed on the valve seat and connected to the valve seat to form a vapor cavity; and a grill that is removably mounted on the valve seat and supported between the valve cover and the valve seat.

Additionally, in the steam valve provided in the aforementioned embodiment of the present invention, by installing the grill on the valve seat, the path of steam flow in the steam cavity can be effectively increased, which improves the anti-spill effect of the product.

Since the lattice is detachably mounted on the valve seat, for convenience, the valve lattice and valve seat can be detached for complete cleaning, thereby avoiding problems when clumps of rice broth and the like formed during rice stick to the dead zone formed between the lattice and valve seat, which leads to difficult cleaning or incomplete cleaning, as well as to problems of blocking the steam cavity of the steam valve, poor defoaming effect, increase the cooking time of rice and similar, due to the difficulty of cleaning or incomplete cleaning of the grate. The grille is detachably mounted on the valve seat, which not only facilitates the cleaning of the grille and valve seat, but also guarantees the effect of using a steam valve.

In addition, a grill is supported between the valve cover and the valve seat, while functioning to support the valve cover well, effectively increasing the strength of the valve structure and preventing thermal distortion of the valve cover. In particular, for a steam valve with relatively large sizes, as the size of the valve cover increases, the strength of the valve cover decreases, and the valve cover becomes sensitive to thermal deformation. Thus, placing the grill between the valve cover and the valve seat better prevents thermal deformation of the valve cover.

In addition, the steam valve provided by the aforementioned embodiment of the present invention also has the following additional technical features:

In the aforementioned technical solution, the grill is preferably clamped on the valve seat.

The grille is detachably mounted on the valve seat in a clamped state, so that the structure is simple, detachment and installation become easier, and the grille can be detached for convenience for cleaning. Alternatively, the grill can also be attached to the valve seat using fasteners such as screws or the like.

In some embodiments, the valve seat preferably comprises a bottom wall and a female rib extending upward from the edge of the lower wall, first latches protruding inwardly located on the female rib, second latches protruding outwardly located on the edge of the grill, the second latches overlapping the first latches and clamped by the first latches.

The first latch protruding inwardly is located on the female rib of the valve seat to form a confining space between the bottom wall of the valve seat, the female rib and the first latch. When the grill is installed, the second latch on the grill is latched into the confining space below the first latch to firmly install the grill on the valve seat, and when the grill is removed, the second latch on the grill moves outward to detach from the first latch, so that the grill can be easily detached for cleaning .

In some embodiments, the lattice is preferably provided with at least one second latch at its two opposite ends, respectively, and the first latches corresponding to the second latches are respectively located on the valve seat, the second latch located at one end of the lattice latches below the first latch, and a second latch located at the other end of the grating latches with a first latch.

The grill is provided with at least one second latch at its two opposite ends, respectively, and the first latches corresponding to the second latches, respectively, are located on the valve seat. During assembly, a second latch located at one end of the grate is latched below its first latch on the valve seat, and then a second latch located at the other end of the grate is latched below its first latch on the valve seat, thereby making the grate firmly mounted on valve seat, so the design is simple, and assembly becomes easier.

In some embodiments, the bottom surface of the second latch located at least at one end of the grate is preferably provided with a guide inclined plane that has a gradual tilt up towards its free end; and / or the upper surface of the first latch corresponding to the second latch located at least at one end of the grate is provided with a guide inclined plane that has a gradual downward inclination in the direction of its free end.

The guide inclined plane is located on the lower surface of the second latch, and the guide inclined plane is located on the upper surface of the first latch, so that the second latch can be easily latched below the first latch along the guide of the inclined plane, thereby facilitating assembly and saving time and effort.

In some embodiments, the lattice is a plastic lattice, and pressing the lattice in the opposite direction to the protruding portion of the second latch causes the second latch to move inward and to detach from the first latch.

To detach the lattice, the lattice is pressed in the direction opposite to the protruding part of the second latch on the lattice by deforming the plastic lattice, forcing the second latch to move inward and detach from the lower side of the first latch, so that the lattice is disconnected from the valve seat to be cleaned and removed the problem is that the grille is difficult to detach after installing it on the valve seat.

In other words, the simplicity of the assembly and disassembly of the lattice is ensured by the interaction of the first latch and the second latch and the deformation of the lattice, while solving the problems of complex assembly and time spent in the installation of the lattice and the difficulty of disconnecting the lattice after its installation.

According to one embodiment of the present invention, two of the second latches are located at one end of the lattice, at least one second latch is located at the other end of the lattice, and the first latches corresponding to the second latches are respectively located on the valve seat, the dimensions of said two of the second latches, located at one end of the lattice are different, and the dimensions of these two latches from the first latches, which are in one-to-one correspondence with the indicated two latches from the second latches, respectively are perfectly sized to the two latches from the second latches.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill mounted on the valve seat is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat. For this reason, during the assembly of the grate, it is possible to install the grate back. To avoid the situation when the grille is installed on the back side, two second latches, having different sizes, are located on one end of the grill, and the first two latches, having different sizes corresponding to them, are located on the valve seat, thereby realizing the effect of protection against improper installation in the process assembly of the lattice and solving the problem that arises when during the assembly of the lattice there is the possibility of installing the lattice on the back side.

According to one embodiment of the present invention, two of the second latches are located at one end of the lattice, at least one latch of the second latches is located at the other end of the lattice, and the first latches corresponding to the second latches are respectively located on the valve seat, while the lattice has a whole axisymmetric design, and the distance from the two latches from the second latches on the specified one end of the lattice to the axis of symmetry of the lattice is not the same. Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill mounted on the valve seat is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat. For this reason, during the assembly of the grate, it is possible to install the grate back. To avoid the situation when the grille is installed on the back side, two second latches having unequal distances from the axis of symmetry of the lattice are located at one end of the lattice, and the first two latches corresponding to it are located on the valve seat, thereby realizing protection against improper installation during assembly of the lattice and solving the problem that arises when during the assembly of the lattice there is the possibility of installing the lattice on the back side.

According to one embodiment of the present invention, one of the second latches is located at one end of the lattice, at least one of the second latches is located at the other end of the lattice, and the first latches corresponding to the second latches are respectively located on the valve seat, and the lattice has a generally axisymmetric design and the second latch located at the indicated one end of the grating is deflected from the axis of symmetry of the grating.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill mounted on the valve seat is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat. For this reason, during the assembly of the grate, it is possible to install the grate back. In order to avoid the situation when the grille is installed on the back side, one second latch is located at one end of the grill, the second latch is located with a deviation from the axis of symmetry of the grill, and one first latch corresponding to it is located on the valve seat, thereby realizing the effect of protection against incorrect installation during the assembly of the lattice and solving the problem that occurs when during the assembly of the lattice there is the possibility of installing the lattice on the reverse side.

In some embodiments, a vapor inlet is formed in the valve seat, the grill comprises a plurality of blocking ribs surrounding the vapor inlet, vapor channels are enclosed between adjacent blocking ribs, and lattice grooves are formed in the blocking ribs to communicate adjacent vapor channels.

The grate contains a plurality of blocking ribs surrounding the steam inlet, vapor channels are enclosed between adjacent blocking ribs, and two adjacent steam channels communicate with each other through the grooves of the grating in the blocking ribs to increase the path of steam flow in the vapor cavity after entering the vapor cavity, and thus realize a good defoaming effect and sufficiently separate the rice grains, rice broth and the like, captured by the steam from the steam, and return them to the steam cavity and, thus, to protivoprolivochnogo evolve a good effect.

In some embodiments, the gap width between adjacent blocking ribs is at least 7 mm to ensure that a human finger can be inserted into the space between two adjacent blocking ribs and objects are removed in the blocking ribs, and thus the problem of the complexity of the complete cleaning the grill.

In some embodiments, the width of the gap between adjacent blocking ribs does not exceed 10 mm, so that the number of blocking ribs can be effectively increased in a space having the same size to increase the number of steam channels limited by the blocking ribs, thereby further increasing the steam flow path in the steam canals and achieving good antifoam and anti-bleeding effects.

In addition, in some embodiments, the width of the gap between adjacent locking ribs is adjusted within the range of 7-10 mm, which not only solves the problem of the difficulty of completely cleaning the grill, but also guarantees a good anti-spill effect of the steam valve. Obviously, the gap between adjacent blocking ribs is not limited to the specific range defined above, and can be set within reasonable limits in accordance with actual conditions.

In some embodiments, the thickness of the blocking rib is 1-2 mm, which can guarantee the strength of the grating without affecting its deformability.

In some embodiments, a reinforcing rib is located on the upper wall of the valve cover.

A reinforcing rib is located on the valve cover of the steam valve to effectively increase the strength of the valve cover and prevent deformation of the valve cover caused by too high a process temperature. In particular, for a steam valve with a relatively large size, as the size of the valve cover increases, the strength of the valve cover may decrease, and the valve cover becomes sensitive to thermal deformation. By installing a reinforcing rib on the valve cover, the effect of preventing thermal deformation of the valve cover is more noticeable.

In some embodiments, a reinforcing rib is formed by making the inner surface of the upper wall of the valve cover extend downward.

The reinforcing rib is formed by making the outer surface of the upper wall of the valve cover extending downward. That is, the upper wall of the valve cover is made in the form of a concave-convex structure to effectively increase the strength of the valve cover and to achieve the effect of preventing thermal deformation of the valve cover, so that the structure is simple and manufacturing is convenient.

In some embodiments, a reinforcing rib is formed by making the inner surface of the upper wall of the valve cover extend downward.

To increase the structural strength of the valve cover, a convex rib extending downward is located directly on the inner surface of the upper wall of the valve cover, which can also contribute to increase the structural strength of the valve cover.

In some embodiments, the reinforcing rib and the top wall of the valve cover are a one-piece die cast structure.

Since the reinforcing rib and the upper wall of the valve cover are a one-piece injection molded structure, the structural strength of the valve cover is ensured and easy processing and convenient molding of the reinforcing rib are ensured.

In some embodiments, the height of the reinforcing rib is 0.5-2 mm.

The design of a reinforcing rib with a height of 0.5-2 mm not only prevents a situation in which the effect of effectively preventing deformation of the valve cover cannot be achieved when the height of the reinforcing rib is too small, but also avoids interference with the normal assembly of other structures between the valve cover and the valve seat, when the height of the reinforcing rib is very large.

In some embodiments, a plurality of reinforcing ribs are located on the inner surface of the upper wall of the valve cover, and the gap width between adjacent reinforcing ribs is 1.5-3 mm.

The design of the gap between adjacent reinforcing ribs with a width of 1.5-3 mm not only prevents a situation in which the effect of effectively preventing deformation of the valve cover cannot be achieved when the width of the gap between adjacent reinforcing ribs is too large, but also avoids a situation in which the processing complexity increases when the gap width between adjacent reinforcing ribs is too small.

In some embodiments, the grill comprises a plurality of vertically arranged blocking ribs, and the upper wall of the valve cover is supported by the blocking ribs.

The grill comprises a plurality of vertically arranged locking ribs, and this plurality of locking ribs supports the upper wall of the valve cover, thereby effectively improving the supporting effect of the grill for the valve cover, and making the effect of preventing thermal deformation of the valve cover obvious.

In some embodiments, a plurality of reinforcing ribs are located on the inner surface of the upper wall of the valve cover, the shapes of the reinforcing ribs correspond to the indicated vapor channels, limiting grooves with open lower ends are formed between adjacent reinforcing ribs, and the upper ends of the locking ribs are limited in the limiting grooves.

Reinforcing ribs are additionally located on the steam valve cover to effectively increase the strength of the valve cover and to prevent deformation of the valve cover caused by too high a process temperature. In particular, for a steam valve with relatively large sizes, as the size of the valve cover increases, the strength of the valve cover decreases, the valve cover becomes sensitive to thermal deformation. By installing reinforcing ribs on the valve cover, the effect of preventing thermal deformation of the valve cover is more noticeable. Also, the upper ends of the locking ribs are limited in the limiting grooves formed between adjacent reinforcing ribs, thereby fixing the grate, while solving the problem that arises when the grating is not firmly fixed in the vapor cavity and is able to move.

The valve cover and valve seat are preferably made of plastic, thereby not only facilitating the formation of the valve cover and valve seat, but also facilitating the smooth assembly of the valve cover and valve seat. In addition, since the grill is a plastic grill, it is convenient for forming the grill, and it is easy to assemble the grill smoothly on the valve seat. More preferably, the grate is made of high temperature plastic to avoid deformation of the grate caused by too high a vapor temperature in the vapor cavity.

An embodiment of another aspect of the present invention provides a cooking device comprising: a top cover, wherein the top cover is provided with a mounting cavity; and a steam valve described in any of the above paragraphs installed in the installation cavity.

Since the cooking device according to the aforementioned embodiment of the present invention comprises a steam valve described in any of the above embodiments, the cooking device has the positive effects of the steam valve described in any of the above embodiments.

According to one embodiment of the present invention, the cooking device is a rice cooker or an electric double boiler.

DETAILED DESCRIPTION OF THE INVENTION

So that the above objectives, features and advantages of the present invention can be understood more clearly, the following is a detailed description of the present invention in combination with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

The following description sets forth many specific details in order to provide a thorough understanding of the present invention. However, the present invention may also be practiced in other ways than those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

A steam valve and a cooker according to some embodiments of the present invention are described below with reference to the accompanying drawings.

FIRST IMPLEMENTATION

As shown in FIG. 1-6, a steam valve according to some embodiments of the present invention comprises a valve seat 10, a valve cover 20, and a grill 30.

The valve cover 20 is formed on the valve seat 10 and connected to the valve seat 10 to form a vapor cavity. The grill 30 is detachably mounted on the valve seat 10 and is supported between the valve cover 20 and the valve seat 10.

According to the design of the steam valve provided by the aforementioned embodiment of the present invention, the grill 30 is mounted on the valve seat 10 to effectively increase the steam flow path in the steam cavity, thereby improving the anti-spill effect of the product. Since the grill 30 is detachably mounted on the valve seat 10, the valve grill 30 and valve seat 10 are easy to detach for complete cleaning, thereby avoiding problems when clumps of rice broth and the like stick to the dead zone between the grill 30 and the saddle 10 valves, which leads to difficult cleaning or incomplete cleaning, and solving the problems of blocking the steam cavity of the steam valve, poor defoaming effect, increasing the cooking time of rice and the like caused by cleaning or incomplete cleaning of the grill 30. In other words, the grill 30 is detachably mounted on the valve seat 30, thereby facilitating cleaning of the grill 30 and valve seat 10 and guaranteeing the effect of using the steam valve.

In addition, the grill 30 is supported between the valve cover 20 and the valve seat 10, while functioning to reliably support the valve cover 20, effectively increasing the structural strength of the steam valve and preventing thermal deformation of the valve cover 20. In particular, for a steam valve with relatively large sizes, as the size of the valve cover 20 increases, the strength of the valve cover 20 decreases, and the valve cover becomes sensitive to thermal deformation. Thus, between the valve cover 20 and the valve seat 10, an additional grill 30 is provided to better prevent thermal deformation of the valve cover 20.

In the above embodiment shown in FIG. 1, the grill 30 is preferably clamped on the valve seat 10.

The grill 30 is detachably mounted on the valve seat 10 in a clamped state, so that the structure is simple, the detachment and installation are facilitated, and the grill 30 is easy to detach and clean.

In one embodiment of the present invention, as shown in FIG. 1, 3, 4, and 5, the valve seat 10 comprises a lower wall and a female rib 102 extending upward from the edge of the lower wall. The first latches 103 protruding inwardly are located on the enclosing rib 102, the second latches 304 protruding outwardly are located on the edge of the lattice 30, and the second latches 304 overlap the latches 103 and are clamped by the first latches 103.

The first latches 103 protruding inwardly are located on the enclosing rib 102 of the valve seat 10 to form a confining space between the bottom wall of the valve seat 10, enclosing the rib 102 and the first latch 103. When the grill 30 is installed, the second latch 304 on the grill 30 latches into the limiting space below the first latch 103 to firmly install the grill 30 on the valve seat 10. In addition, during disassembly, the second latch 304 on the grate 30 is moved outward so that it is disconnected from the first latch 103 and thus the grate 30 can be easily detached and cleaned.

In the above embodiment, as shown in FIG. 1, 4 and 5, the grill 30 is preferably provided with at least one second latch 304 at two opposite ends, respectively, and the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. In particular, a second latch 304 located at one end of the grate 30 is latched below the first latch 103, and a second latch 304 located at the other end of the grate 30 is latched by the first latch 103.

In the case where the grill 30 is provided with at least one second latch 304 at two opposite ends, respectively, and the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10, during assembly a second latch 304 located at one end of the lattice 30 are latched below the corresponding first latch 103 on the valve seat 10, and then a second latch 304 located on the other end of the grill 30 is latched below the corresponding first latch 103 on the valve seat 10. Thus, a secure installation of the grill 30 on the valve seat 10 is ensured, so that the structure is simple and assembly is convenient.

In the above embodiment, as shown in FIG. 5, the lower surface of the second latch 304, located at least at one end of the grate 30, is preferably provided with a guide inclined plane, which has a gradual tilt up in the direction of its free end. The upper surface of the first latch 103, corresponding to the second latch 304, located at least at one end of the grate 30, is provided with a guide inclined plane that has a gradual downward inclination in the direction of its free end.

The guide inclined plane is located on the lower surface of the second latch 304, and the guide inclined plane is located on the upper surface of the first latch 103 so that the second latch 304 can smoothly snap below the first latch 103 along the guide inclined plane. Thus, assembly can be simplified and time and effort saved.

In the above embodiment, the grill 30 is preferably a plastic grill, and when the grill 30 is pressed in the direction opposite to the protruding portion of the second latch 304, the second latch 304 can be made to move inward and detach from the first latch 103.

To detach the lattice 30, the lattice 30 is pressed in the opposite direction to the protruding portion of the second latch 304 on the lattice 30 by deforming the plastic lattice 30, causing the second latch 304 to move inward and detach from the lower side of the first latch 103, so that the lattice 30 is detached from the seat 10 valve and is cleaned. Thus, the problem of the complex detachment of the grill 30 after installing the valve on the seat 10 is solved.

In other words, the ease of assembly and disassembly of the grill 30 is ensured by the interaction of the first latch 103 and the second latch 304 and the deformation of the grill 30. In addition, the problems of complex assembly and time spent during installation of the grill 30 and the difficulties in disconnecting the grill after installation are solved.

In one embodiment of the present invention, as shown in FIG. 2 and 3, two second latches 304 are located at one end of the lattice 30, at least one second latch 304 is located at the other end of the lattice 30, and the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. In particular, the dimensions of the two second latches 304 located at one end of the grating 30 are different, and the sizes of the two first latches 103, which are in one-to-one correspondence with the second latches 304, are accordingly adapted to the dimensions of the two second latches 304.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill 30 mounted on the valve seat 10 is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat 10. In this case, during the assembly of the grill 30, it is possible to install the grille on the back side. In order to avoid a situation where the grill 30 is installed on the back side, two second latches 304, having different sizes, are located on one end of the grill 30, and two first latches 103, having different sizes corresponding to it, are located on the valve seat 10, thereby realizing the effect protection against improper installation during the assembly of the lattice 30 and solving the problem when during the assembly of the lattice 30 there is the possibility of installing the lattice on the reverse side.

In another embodiment of the present invention, two second latches 304 are located at one end of the grill 30, at least one second latch 304 is located at the other end of the grill 30, and the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. In addition, the lattice 30 has a generally axisymmetric design and the distances from the two second latches 304 at one end of the lattice 30 to the axis of symmetry of the lattice 30 are not equal.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill 30 mounted on the valve seat 10 is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat 10. Thus, it is possible to install the grill 30 with the back side during the assembly of the grill 30. To avoid the situation when the grill 30 is installed with the back side, two second latches 304 having unequal distances from the axis of symmetry of the grill 30 are located at one end of the grill 30, and the first two the latches 103 corresponding to it are located on the valve seat 10, thereby realizing the effect of protection against improper installation during the assembly of the grill 30 and solving the problem when it is possible to install yeskhetki reverse side.

In yet another embodiment of the present invention, one second latch 304 is located at one end of the grill 30, at least one second latch 304 is located at the other end of the grill 30, and first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. In addition, the lattice 30 has a generally axisymmetric design and the second latch 304, located at one end of the lattice 30, is deviated from the axis of symmetry of the lattice 30.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill 30 mounted on the valve seat 10 is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat 10. Thus, it is possible to install the grate 30 on the back side during the assembly of the grate 30. To avoid the situation where the grate 30 is installed on the back side, one second latch 304 is located at one end of the grate 30, said second latch 304 is located with a deviation from the axis of symmetry of the grate 30 and one first latch 103 corresponding to it is located on the valve seat 10, thereby realizing the effect of protection against improper installation during the assembly of the grill 30 and solving the problem when creatures in the grille 30 are assembled possibility of installing a reverse side of the lattice.

In one embodiment of the present invention, as shown in FIG. 1, a steam inlet 101 is formed on the valve seat 10, a steam outlet 203 is formed on the valve cover 20, the grill 30 comprises a plurality of blocking ribs 301 surrounding the steam inlet 101, steam channels 302 are enclosed between adjacent blocking ribs 301, and grille grooves are made in the blocking ribs 301 (not shown in the figure) for communicating adjacent steam channels 302.

The grate 30 comprises a plurality of blocking fins 301 surrounding the steam inlet 101, steam channels 302 are enclosed between adjacent blocking fins 301, and two adjacent steam channels 302 communicate with each other through the slots of the grating in the blocking fins 301 to increase the flow path of the vapor in the vapor cavity after entering a vapor cavity so that a good defoaming effect can be realized. In addition, rice grains captured by steam, rice broth and the like can sufficiently separate from the steam and return to the steam cavity, and thus a good anti-spill effect is achieved.

In the above embodiment shown in FIG. 1 and 2, the width of the gap between adjacent blocking fins 301 is preferably not less than 7 mm to ensure that a human finger can be inserted into the space between two adjacent blocking fins 301 to remove objects in the blocking fins 301. Thus, the problem of complexity cleaning lattice 30 is completely solved.

In the above embodiment shown in FIG. 1 and 2, the width of the gap between adjacent blocking ribs 301 is preferably not more than 10 mm, so that the number of blocking ribs 301 can be effectively increased in a space having the same size to increase the number of steam channels 302 limited by the blocking ribs 301. Thus, the steam flow path in the steam channels 302 is further increased and a good defoaming and anti-spilling effect can be achieved.

Preferably, as shown in FIG. 2, the gap width between adjacent blocking ribs 301 is set within the range of 7-10 mm, which not only solves the problem of the difficulty of completely cleaning the grill, but also guarantees a good anti-spill effect of the steam valve. Obviously, the gap between adjacent blocking ribs 301 is not limited to the specific range defined above, and can be reasonably set in accordance with the actual conditions that should fall within the scope of legal protection of the present invention, provided that this does not depart from the idea of the present invention .

In the aforementioned embodiment, the thickness of the blocking rib 301 is preferably 1-2 mm, which can guarantee the strength of the grating 30 without affecting the deformability of the grating 30.

Furthermore, as shown in FIG. 1 and 2, a connecting rib 303 is placed between adjacent blocking ribs 301 and the vertical height of the connecting rib 303 is less than the height of the blocking rib 301. Alternatively, a through hole (not shown in the figure) is formed in the connecting rib 303 for the passage of steam.

A connecting rib 303 is placed between adjacent locking ribs 301 to increase the overall structural strength of the grill 30. The vertical height of the connecting rib 303 is less than the height of the locking rib 301, or a through hole is formed in the connecting rib 303 to ensure that the steam flows in steam channels 302, enclosed between adjacent blocking fins 301, does not depend on the location of the connecting ribs 303.

In one embodiment of the present invention, as shown in FIG. 6, a plurality of reinforcing ribs 201 are arranged on the inner surface of the upper wall of the valve cover 20, the shapes of the reinforcing ribs 201 correspond to the indicated steam channels 302, limiting grooves 202 with open lower ends are formed between adjacent reinforcing ribs 201, and the upper ends of the locking ribs 301 are limited in the limiting grooves 202.

Reinforcing ribs 201 are further located on the valve cover 20 of the steam valve to effectively increase the strength of the valve cover 20 and to prevent deformation of the valve cover 20 caused by too high a process temperature. In particular, for a steam valve with relatively large sizes, as the size of the valve cover 20 increases, the strength of the valve cover 20 decreases and the valve cover becomes sensitive to thermal deformation. Since reinforcing ribs 201 are located on the valve cover 20, the effect of preventing thermal deformation of the valve cover 20 is more noticeable. In addition, the upper ends of the blocking ribs 301 are bounded in the limiting grooves 202 formed between adjacent reinforcing ribs 201, thereby fixing the grating 30 and solving the problem that occurs when the grating 30 is loosely fixed in the vapor cavity and is able to move.

SECOND EMBODIMENT

As shown in FIG. 1-6, a steam valve according to some embodiments of the present invention comprises a valve seat 10 and a valve cover 20.

A valve cover 20 is provided on the valve seat 10 and is connected to the valve seat 10 to form a vapor cavity. A reinforcing rib 201 is located on the upper wall of the valve cover 20.

In the steam valve provided by the aforementioned embodiment of the present invention, a reinforcing rib 201 is located on the upper wall of the valve cover 20 to effectively increase the strength of the valve cover 20 and prevent deformation of the valve cover 20 caused by too high a process temperature. In particular, for a steam valve with relatively large sizes, as the size of the valve cover 20 increases, the strength of the valve cover 20 may decrease. In addition, since the reinforcing rib 201 is located on the valve cover 20, preventing thermal distortion of the valve cover 20 is more pronounced.

In one embodiment of the present invention, as shown in FIG. 1 and 6, reinforcing rib 201 is formed by deepening down the outer surface of the upper wall of the valve cover 20.

Reinforcing rib 201 is formed by making the outer surface of the upper wall of the valve cover 20 with a recess down. Thus, the upper wall of the valve cover 20 is made in the form of a concave-convex structure to effectively increase the strength of the valve cover 20 and to prevent thermal deformation of the valve cover 20. Thus, the design is simple, and the manufacture is convenient.

In another embodiment of the present invention, reinforcing rib 201 is formed by making the inner surface of the upper wall of the valve cover 20 extend downward.

To increase the structural strength of the valve cover 20, a convex rib protruding downward is located directly on the inner surface of the upper wall of the valve cover 20, which can also help increase the structural strength of the valve cover 20.

In the aforementioned embodiment, the reinforcing rib 201 and the upper wall of the valve cover 20 are preferably a one-piece die-cast structure, thus the strength of the valve cover 20, the ease of processing of the reinforcing rib 201, and the ease of forming the reinforcing rib 201 can be guaranteed.

In the aforementioned embodiment, the height of the reinforcing rib 201 is preferably 0.5-2 mm.

The design of reinforcing ribs 201 with a height of 0.5-2 mm not only prevents the situation in which it is impossible to effectively prevent deformation of the valve cover 20 when the height of the reinforcing ribs 201 is too small, but also avoids interference with the normal assembly of other structures between the valve cover 20 and the valve seat 10 when the height of the reinforcing rib 201 is very large.

In the aforementioned embodiment, the plurality of reinforcing ribs 201 are preferably located on the inner surface of the upper wall of the valve cover 20 and the gap width between adjacent reinforcing ribs 201 is 1.5-3 mm.

The design of the gap between adjacent reinforcing ribs 201 of a width of 1.5-3 mm not only prevents a situation in which it is impossible to achieve the effect of preventing deformation of the valve cover 20, when the width of the gap between adjacent reinforcing ribs 201 is too large, but also avoids a situation in which processing complexity when the gap width between adjacent reinforcing ribs 201 is too small.

The height of the reinforcing ribs 201 and the width of the gap between adjacent reinforcing ribs 201 are not limited to the specific range defined above, and can be set within reasonable limits in accordance with actual conditions.

In one embodiment of the present invention shown in FIG. 1, the steam valve further comprises a grill 30 located in the steam cavity and supported between the valve cover 20 and the valve seat 10.

In the case where the grill 30 is located between the valve cover 20 and the valve seat 10 and the grill 30 is supported between the valve cover 20 and the valve seat 10, the grill 30 operates to reliably support the valve cover 20 and effectively prevents thermal deformation of the valve cover 20.

Furthermore, as shown in FIG. 1, the grill 30 comprises a plurality of vertically arranged blocking ribs 301 and the upper wall of the valve cover 20 is supported on the blocking ribs 301.

The grill 30 comprises a plurality of vertically arranged blocking ribs 301 that support the upper wall of the valve cover 20, thereby effectively improving the supporting effect of the grill 30 for the valve cover 20, and the effect of preventing thermal deformation of the valve cover 20 is obvious.

In the above embodiment shown in FIG. 1, a steam inlet 101 is preferably formed in the valve seat 10, a steam outlet 203 is formed in the valve cover 20, a plurality of blocking ribs 301 surrounds the steam inlet 101, steam channels 302 are enclosed between adjacent blocking ribs 301, and lattice grooves are made in the blocking ribs 301 (not shown in the figure) for communicating adjacent steam channels 302.

A plurality of blocking fins 301 surrounds the steam inlet 101 in the valve seat 10, steam channels 302 are enclosed between adjacent blocking fins 301, and two adjacent steam channels 302 communicate with each other through grating slots in the blocking fins 301 to increase the flow path of the vapor in the vapor cavity after entering steam cavity, so that a good defoaming effect is realized, rice grains, rice broth and the like, captured by the steam can sufficiently separate from the steam and return to the steam cavity. Thus, a good anti-spill effect is achieved.

In the above embodiment shown in FIG. 1, the connecting rib 303 is preferably connected between adjacent blocking ribs 301 and the vertical height of the connecting rib 303 is less than the height of the blocking rib 301. Alternatively, a through hole is provided in the connecting rib 303 for the passage of steam.

A connecting rib 303 is placed between adjacent locking ribs 301 to increase the overall structural strength of the grill 30. The vertical height of the connecting rib 303 is less than the height of the locking rib 301, or a through hole is formed in the connecting rib 303 to ensure that the steam flows in steam channels 302 enclosed between adjacent blocking fins 301 is independent of the location of the connecting fins 303.

In the above embodiment shown in FIG. 1 and 6, a plurality of reinforcing ribs 201 are preferably arranged on the inner surface of the upper wall of the valve cover 20, bounding grooves 202 with open lower ends are formed between adjacent reinforcing ribs 201, and the upper ends of the locking ribs 301 are bounded in the limiting grooves 202.

The upper ends of the locking ribs 301 are bounded in the limiting grooves 202 formed between adjacent reinforcing ribs 201, thereby securing the grill 30 and solving the problem that occurs when the grill 30 is loosely fixed in the vapor cavity and is able to move.

The shapes of the reinforcing ribs 201 preferably correspond to these steam channels 302 enclosed between adjacent blocking ribs 301.

In one embodiment of the present invention shown in FIG. 1, the valve seat 10 includes a bottom wall and a female rib 102 extending upward from the edge of the lower wall, the first latches 103 protruding inwardly, located on the female rib 102, the second latches 304 protruding outward, located on the edge of the grill 30, and the second latches 304 overlap the latches 103 and clamped by the first latches 103.

The grill 30 is clamped on the valve seat 10, which not only guarantees the strength of the assembly between the grill 30 and the valve seat 10, but also facilitates the detachment of the grill 30 for complete cleaning. Thus, the problem when clots of rice broth and the like formed during the preparation of rice adhere to the dead zone between the grill 30 and the valve seat 10, which leads to difficult cleaning or incomplete cleaning, is solved.

Obviously, the grill 30 can also be attached to the valve seat 10 in another way, for example, by means of a screw connection.

THIRD EMBODIMENT

An embodiment is a combination of a first embodiment and a third embodiment.

As shown in FIG. 1-6, a steam valve according to some embodiments of the present invention comprises a valve seat 10, a valve cover 20, and a grill 30.

The valve cover 20 is formed on the valve seat 10 and connected to the valve seat 10 to form a vapor cavity. The grill 30 is detachably mounted on the valve seat 10 and is supported between the valve cover 20 and the valve seat 10.

According to the steam valve provided in the aforementioned embodiment of the present invention, the grill 30 is mounted on the valve seat 10 to effectively increase the steam flow path in the steam cavity, thereby improving the anti-spill effect of the product. Since the grill 30 is detachably mounted on the valve seat 10, the valve grill 30 and valve seat 10 are easy to detach for complete cleaning, thereby avoiding problems when clumps of rice broth and the like stick to the dead zone between the grill 30 and the saddle 10 valves, which leads to difficult cleaning or incomplete cleaning, and solving the problem of blocking the steam cavity of the steam valve, poor defoaming effect, increasing the cooking time of rice and the like caused by cleaning or incomplete cleaning of the grill 30. In other words, the grill 30 is detachably mounted on the valve seat 30, which not only facilitates cleaning of the grill 30 and valve seat 10, but also guarantees the effect of using the steam valve.

In addition, the grill 30 is supported between the valve cover 20 and the valve seat 10, while functioning to reliably support the valve cover 20, effectively increasing the structural strength of the valve and preventing thermal deformation of the valve cover 20. In particular, for a steam valve with relatively large sizes, as the size of the valve cover 20 increases, the strength of the valve cover 20 decreases, and the valve cover becomes sensitive to thermal deformation. Therefore, between the valve cover 20 and the valve seat 10, an additional grill 30 is arranged to provide a better effect of preventing thermal deformation of the valve cover 20.

In the above embodiment shown in FIG. 1, the grill 30 is preferably clamped on the valve seat 10.

The grill 30 is detachably mounted on the valve seat 10 in a clamped state, so that the structure is simple, the detachment and installation become easier, and the grill 30 is easy to detach and clean.

In one embodiment of the present invention, as shown in FIG. 1, 3, 4, and 5, the valve seat 10 comprises a lower wall and a female rib 102 extending upward from the edge of the lower wall, the first latches 103 protruding inwardly on the female rib 102, and the second latches 304 protruding outwardly on the edge of the grill 30 and the second latches 304 overlap the latches 103 and are clamped by the first latches 103.

The first latches 103 protruding inwardly are located on the enclosing rib 102 of the valve seat 10 to form a confining space between the lower wall of the valve seat 10, enclosing the rib 102 and the first latch 103. When the grill 30 is installed, the second latch 304 on the grill 30 latches in the limiting space below the first latch 103, so as to firmly install the grill 30 on the valve seat 10. During disassembly, the second latch 304 on the grate 30 moves outward to detach from the first latch 103. Thus, the grate 30 is conveniently detached and cleaned.

In the above embodiment, as shown in FIG. 1, 4 and 5, the grill 30 is preferably provided with at least one second latch 304 at each of the two opposite ends, respectively, and the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. In particular, a second latch 304 located at one end of the grate 30 is latched below the first latch 103, and a second latch 304 located at the other end of the grate 30 is latched by the first latch 103.

In the case where the grill 30 is provided with at least one second latch 304 at each of the two opposite ends, respectively, the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. During assembly, a second latch 304, located at one end of the grill 30, is latched below its corresponding first latch 103 on the valve seat 10, and then a second latch 304, located at the other end of the grill 30, is latched below its first latch 103 on the valve seat 10 to ensure a secure installation of the grill 30 on the valve seat 10. In this way, the structure is simplified and assembly is facilitated.

In the above embodiment, as shown in FIG. 5, the lower surface of the second latch 304, located at least at one end of the grate 30, is preferably provided with a guide inclined plane that has a gradual tilt up towards its free end, and the upper surface of the first latch 103, corresponding to the second latch 304, located at least at least at one end of the grate 30, provided with a guide inclined plane, which has a gradual tilt down in the direction of its free end.

The guide inclined plane is located on the lower surface of the second latch 304, and the guide inclined plane is located on the upper surface of the first latch 103, so that the second latch 304 can smoothly snap below the first latch 103 along the guide of the inclined plane. Thus, assembly can be simplified and time and effort saved.

In the above embodiment, the grill 30 is preferably a plastic grill. When the grate 30 is pressed in the opposite direction to the protruding portion of the second latch 304, the second latch 304 can be made to move inward and detach from the first latch 103.

To detach the lattice 30, the lattice 30 is pressed in the opposite direction to the protruding portion of the second latch 304 on the lattice 30 by deforming the plastic lattice 30, causing the second latch 304 to move inward and detach from the lower side of the first latch 103. Thus, the lattice 30 can be disconnected from the valve seats 10 and clean, and the problem of difficult detachment of the grill 30 after installation on the valve seat 10 is solved.

In other words, the effect of simple assembly and disassembly of the grate 30 is realized by ensuring the interaction of the first latch 103 and the second latch 304 and the deformation of the grate 30. Thus, the problems of complex assembly and time spent during the installation of the grate 30 and the difficulty of disconnecting the grate after installation are solved.

In one embodiment of the present invention, as shown in FIG. 2 and 3, two second latches 304 are located at one end of the lattice 30, at least one second latch 304 is located at the other end of the lattice 30, and the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. In addition, the dimensions of the two second latches 304 located at one end of the grill 30 are different, and the sizes of the two first latches 103, which are in one-to-one correspondence with the second latches 304, are accordingly adapted to the dimensions of the two said second latches 304.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill 30 mounted on the valve seat 10 is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat 10. Thus, during the assembly of the grill 30, it is possible to install the grill 30 on the reverse side. To avoid the situation where the grille 30 is installed on the back side, two second latches 304, having different sizes, are located on one end of the grill 30, and two first latches 103, having different sizes corresponding to them, are located on the valve seat 10, thereby realizing the protection effect from improper installation during the assembly of the lattice 30 and the solution of the problem when during the assembly of the lattice 30 there is the possibility of installing the lattice 30 on the reverse side.

In another embodiment of the present invention, two second latches 304 are located at one end of the lattice 30, at least one second latch 304 is located at the other end of the lattice 30, and the first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. The grating 30 has a generally axisymmetric design and the distances from the two second latches 304 at one end of the grating 30 to the axis of symmetry of the grating 30 are not equal.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill 30 mounted on the valve seat 10 is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat 10. Thus, during the assembly of the grill 30, it is possible to install the grill 30 on the reverse side. To avoid the situation where the grill 30 is installed on the back side, two second latches 304, having unequal distances from the axis of symmetry of the lattice 30, are located at one end of the lattice 30, and the two first latches 103 corresponding to them are located on the valve seat 10. As a result of this, the effect of protection against improper installation during the assembly of the grill 30 is realized, and the problem when the possibility of installing the grill 30 with the back side during the assembly process is solved.

In yet another embodiment of the present invention, one second latch 304 is located at one end of the grill 30, at least one second latch 304 is located at the other end of the grill 30, and first latches 103 corresponding to the second latches 304 are respectively located on the valve seat 10. The grating 30 has a generally axisymmetric construction and the second latch 304, located at one end of the grating 30, is deviated from the axis of symmetry of the grating 30.

Since the steam valve as a whole is made in the form of a structure with mirror symmetry, the grill 30 mounted on the valve seat 10 is generally made in the form of a structure with mirror symmetry corresponding to the shape of the valve seat 10. Thus, during the assembly of the grill 30, it is possible to install the grill 30 on the reverse side. To avoid the situation where the grill 30 is installed on the back side, one second latch 304 is located at one end of the grill 30, the second latch 304 is located with a deviation from the axis of symmetry of the grill 30, and one first latch 103 corresponding to it is located on the valve seat 10. Thus, the effect of protection against improper installation during the assembly of the grill 30 is achieved, and the problem when there is the possibility of installing the grill 30 with the back side during the assembly process is solved.

The grill can also be attached to the valve seat in another way, for example, by means of a screw connection.

In one embodiment of the present invention shown in FIG. 1, a steam inlet 101 is formed in the valve seat 10, a steam inlet 203 is formed in the valve cover 20, the grill 30 comprises a plurality of blocking ribs 301 surrounding the steam inlet 101, steam channels 302 are enclosed between adjacent blocking ribs 301, and lattice grooves are made in the blocking ribs 301 (not shown in the figure) for communicating adjacent steam channels.

The grate 30 comprises a plurality of blocking fins 301 surrounding the steam inlet 101, steam channels 302 are enclosed between adjacent blocking fins 301, and two adjacent steam channels 302 communicate with each other through the slots of the grating in the blocking fins 301 to increase the steam flow path in the vapor cavity after entering him. In this way, a good anti-foaming effect is provided, rice grains, rice broth and the like, captured by the steam, can sufficiently separate from the steam and return to the steam cavity, and thus a good anti-spill effect is achieved.

In the above embodiment shown in FIG. 1 and 2, the width of the gap between adjacent blocking fins 301 is preferably not less than 7 mm to ensure that a human finger can be inserted into the space between two adjacent blocking fins 301 and objects are removed in the blocking fins 301. Thus, there is a problem with the complexity of the complete cleaning of the grate 30 is solved.

In the above embodiment shown in FIG. 1 and 2, the width of the gap between adjacent blocking ribs 301 is preferably not more than 10 mm, so that the number of blocking ribs 301 can be effectively increased in a space having the same size, and thus the number of steam channels 302 limited by the blocking ribs 301, increases, thereby further increasing the path of the steam flow in the steam channels 302 and achieving good defoaming and anti-spilling effects.

Preferably, as shown in FIG. 2, the gap width between adjacent blocking ribs 301 is set within the range of 7-10 mm, which not only solves the problem of the difficulty of completely cleaning the grill 30, but also guarantees a good anti-spill effect of the steam valve. Obviously, the gap between adjacent blocking ribs 301 is not limited to the specific range defined above, but can be reasonably set in accordance with the actual conditions, which should fall within the scope of legal protection of the present invention, provided that this does not depart from the idea of the present invention .

In the aforementioned embodiment, the thickness of the blocking rib 301 is preferably 1-2 mm, which can guarantee the strength of the grating 30 without affecting the deformability of the grating 30.

Additionally, as shown in FIG. 1 and 2, a connecting rib 303 is placed between adjacent blocking fins 301, and the vertical height of the connecting rib 303 is less than the height of the blocking rib 301. Alternatively, a through hole (not shown in the figure) is provided for the passage of steam in the connecting rib 303.

Between adjacent blocking fins 301, a connecting rib 303 is arranged to increase the overall structural strength of the grating 30. The vertical height of the connecting rib 303 is less than the height of the blocking rib 301, or a through hole is formed in the connecting rib 303 to ensure that the steam flows in the steam the channels 302 enclosed between adjacent blocking ribs 301, does not depend on the location of the connecting ribs 303.

As shown in FIG. 1 and 2, the valve cover 20 is formed on the valve seat 10 and connected to the valve seat 10 to form a vapor cavity, and a reinforcing rib 201 is located on the upper wall of the valve cover 20.

A reinforcing rib 201 is additionally located on the valve cover 20 of the steam valve to effectively increase the strength of the valve cover 20 and prevent deformation of the valve cover 20 caused by too high a process temperature. In particular, for a steam valve with relatively large sizes, as the size of the valve cover 20 increases, the strength of the valve cover 20 may decrease. Since the reinforcing rib 201 is located on the valve cover 20, the effect of preventing thermal deformation of the valve cover 20 is more noticeable.

In one embodiment of the present invention, as shown in FIG. 1 and 2, a reinforcing rib 201 is formed by deepening down the outer surface of the upper wall of the valve cover 20.

The reinforcing rib 201 is formed by deepening down the outer surface of the upper wall of the valve cover 20, and thus, the upper wall of the valve cover 20 is made in the form of a concave-convex structure to effectively increase the strength of the valve cover 20 and to achieve the effect of preventing thermal deformation of the valve cover 20. As a result, the design is simplified, and manufacturing becomes easier.

In another embodiment of the present invention, reinforcing rib 201 is formed by making the inner surface of the upper wall of the valve cover 20 extend downward.

To increase the structural strength of the valve cover 20, a convex rib protruding downward is located directly on the inner surface of the wall of the upper wall of the valve cover 20, which can also increase the structural strength of the valve cover 20.

In the aforementioned embodiment, the reinforcing rib 201 and the upper wall of the valve cover 20 are preferably an integral injection molded structure. As a result, the structural strength of the valve cover 20 and the reinforcing rib 201 can be guaranteed to be easy to handle, and the molding of the reinforcing rib 201 is convenient.

In the aforementioned embodiment, the height of the reinforcing rib 201 is preferably 0.5-2 mm.

In the aforementioned embodiment, a plurality of reinforcing ribs 201 are preferably located on the inner surface of the upper wall of the valve cover 20, and the gap width between adjacent reinforcing ribs 201 is 1.5-3 mm.

The height of the reinforcing ribs 201 and the gap between adjacent reinforcing ribs 201 are not limited to those defined above and can be set within reasonable limits in accordance with actual conditions.

The grill 30 is located in the vapor cavity and is supported between the valve cover 20 and the valve seat 10.

In the case where the grill 30 is located between the valve cover 20 and the valve seat 10 and the grill 30 is supported between the valve cover 20 and the valve seat 10, the grill 30 operates to reliably support the valve cover 20 and effectively prevents thermal distortion of the valve cover 20.

Additionally, as shown in FIG. 1, the grill 30 comprises a plurality of vertically arranged blocking ribs 301 and the upper wall of the valve cover 20 is supported on the blocking ribs 301.

The grill 30 comprises a plurality of vertically arranged blocking ribs 301 and a plurality of blocking ribs 301 supports the upper wall of the valve cover 20. Thus, the supporting effect of the grill 30 for the valve cover 20 is significantly improved, and the effect of preventing thermal deformation of the valve cover 20 is obvious.

In the above embodiment shown in FIG. 1, the steam inlet 101 is preferably formed in the valve seat 10, the steam inlet 203 is formed in the valve cover 20, a plurality of blocking ribs 301 surrounds the steam inlet 101, steam channels 302 are enclosed between adjacent blocking ribs 301, and lattice grooves are made in the blocking ribs 301 (not shown figure) to communicate adjacent steam channels 302. Many of the locking ribs 301 are configured to surround the steam inlet 101 in the valve seat 10, steam channels 302 are enclosed between two adjacent and blocking fins 301 and two adjacent steam channels 302 communicate with each other through the grooves of the grating in the blocking fins 301 to increase the path of steam flow in the vapor cavity after entering the vapor cavity. Thus, a good defoaming effect is ensured, rice grains, rice broth and the like, captured by the steam, can sufficiently separate from the steam and return to the steam cavity, and thus a good anti-spill effect is achieved.

In the above embodiment shown in FIG. 1, the connecting rib 303 is preferably connected between adjacent blocking ribs 301, and the vertical height of the connecting rib 303 is less than the height of the blocking rib 301. Alternatively, a through hole is formed in the connecting rib 303 for the passage of steam.

A connecting rib 303 is placed between adjacent locking ribs 301 to increase the overall structural strength of the grill 30. The vertical height of the connecting rib 303 is less than the height of the locking rib 301, or a through hole is provided in the connecting rib 303 to ensure that the steam flows in steam channels 302 enclosed between adjacent blocking fins 301, does not depend on the location of the connecting fins 303.

Reinforcing ribs 201 are further located on the valve cover 20 of the steam valve to effectively increase the strength of the valve cover 20 and to prevent deformation of the valve cover 20 caused by too high a process temperature. In particular, for a steam valve with relatively large sizes, as the size of the valve cover 20 increases, the strength of the valve cover 20 decreases, and the valve cover becomes sensitive to thermal deformation. Since reinforcing ribs 201 are located on the valve cover 20, the effect of preventing thermal deformation of the valve cover 20 is more noticeable.

The upper ends of the locking ribs 301 are bounded in the limiting grooves 202 formed between adjacent reinforcing ribs 201, thereby fixing the grill 30 and solving the problem that occurs when the grill 30 is loosely fixed in the vapor cavity and is able to move.
