[0001] The invention relates to the technical field of exhaust structures, and in particular to a steam valve, a cover body of a steaming and cooking device, and a steaming and cooking device. Background Art

[0002] Steaming and cooking equipment is a very common electrical equipment in daily life. The main working principle of steaming and cooking equipment is to heat the water inside it and then generate high-temperature steam, and realize steaming, boiling and other operations through high-temperature steam.

[0003] The application field of the steaming and cooking equipment itself is relatively wide. It can be applied to the food field to cook food ingredients. It can also realize the disinfection operation of the items inside the steaming and cooking equipment, such as disinfecting utensils, textiles, etc. by high-temperature cooking.

[0004] In order to achieve air pressure balance, the steaming equipment in the prior art usually needs to be provided with a steam valve, and the steam discharge operation is realized through the steam valve. However, during the steam discharge process, the steam will overflow to the surroundings, and the high-temperature steam will condense after heat exchange with the surrounding low-temperature environment, and then form condensed water on the cover and other places. The condensed water will affect the user experience after being left in the steaming equipment. At the same time, the steam may cause thermal burns to the surrounding personnel after overflowing to the surroundings. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that high-temperature steam overflows from around the steam valve in the cooking equipment in the prior art, affecting the user experience.

[0006] To this end, the present invention provides a steam valve, comprising: a steam valve body, in which a steam channel is arranged;

[0007] The steam channel is provided with a steam inlet and a steam outlet arranged opposite to the steam inlet, and the steam outlet is arranged closer to the center of the steam channel than the steam inlet.

[0008] The steam valve provided by the present invention further includes: a steam upper cover; a steam lower cover, which is arranged below the steam upper cover, and at least a part of the steam lower cover is provided with a guide part, and the guide part is folded to form a part of the steam channel.

[0009] In the steam valve provided by the present invention, the guide portion is arranged in an arc shape.

[0010] In the steam valve provided by the present invention, the inner diameter of the guide portion gradually decreases from bottom to top along the height direction.

[0011] The steam valve provided by the present invention further includes: a raised portion, which is provided on the steam upper cover and extends in a direction away from the steam upper cover, and at least part of the raised portion surrounds the steam channel.

[0012] For the steam valve provided by the present invention, the raised portion includes: a connecting portion, one end of which extends to the steam channel; a boss, which is connected to the connecting portion, and the height of the boss is higher than that of the connecting portion.

[0013] For the steam valve provided by the present invention, one end of the boss close to the connecting portion is inclined.

[0014] The steam valve provided by the present invention further includes: a baffle, which is arranged in the steam channel, and the outer edge of the baffle is inclined towards the steam valve seat.

[0015] For the steam valve provided by the present invention, the baffle is arranged in a bowl shape.

[0016] For the steam valve provided by the present invention, a plurality of ribs are arranged between the baffle and the steam lower cover.

[0017] The present invention provides a cover body for a cooking device, including: a main body, on which a steam valve seat for steam to flow out is provided; the steam valve provided by the present invention, which is arranged on the main body, and the steam channel of the steam valve is communicated with the steam valve seat.

[0018] The cover body for a cooking device provided by the present invention further includes: a driving device, which is arranged on the main body, and the movable end of the driving device is arranged on the steam valve and is adapted to drive the lifting of the steam valve.

[0019] The present invention provides a cooking device, including: the cover body for a cooking device provided by the present invention; a pot body, the cover body for a cooking device is arranged on the pot body, and a water storage portion is arranged in the pot body.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. The present invention provides a steam valve, including: a steam valve body, inside which a steam channel is provided; the steam channel is provided with a steam inlet and an outlet opposite to the steam inlet, and the outlet is closer to the center of the steam channel than the steam inlet.

[0022] In the present invention, since the outlet is closer to the center position of the steam channel than the steam inlet, it can play a guiding role for the high-temperature steam itself, so that the high-temperature steam can gather towards the center direction of the steam channel, thereby effectively avoiding the steam from overflowing outwardly after flowing out of the steam channel.

[0023] 2. The present invention provides a steam valve, wherein the guiding part is arranged in an arc shape. Through the above-mentioned arrangement, the steam entering the inside of the guiding part will gradually converge, thereby effectively improving the convergence effect of the steam, and further helping to converge the steam into a limited area, so as to prevent the steam from overflowing outwardly after flowing out of the steam channel.

[0024] 3. In the steam valve provided by the present invention, since a convex part is arranged on the steam valve, the gathering effect on the steam flowing out of the steam channel can be realized, thereby preventing the high-temperature steam from flowing around from the steam channel position.

[0025] By restricting the flow direction of the high-temperature steam through the convex part, it is possible to prevent the steam from overflowing around after flowing out of the steam channel, and further prevent the high-temperature steam from causing thermal burns to the surrounding operators. At the same time, it can also prevent the steam from contacting the panel and pre-cooling to form condensed water, which has an adverse impact on the surrounding environment.

[0026] Meanwhile, since the inner diameter of the steam outlet is smaller than that of the steam inlet, the steam can be pre-converged. On this basis, combined with the function of the convex part, the steam can be further converged, thus effectively preventing the steam from overflowing.

[0027] 4. In the steam valve provided by the present invention, one end of the convex platform close to the connecting part is arranged in an inclined shape.

[0028] Since the convex platform itself is arranged in an inclined shape, when the high-temperature steam moves to the position of the convex platform, it can be guided by the convex platform to change from a diffused state to a converged state, thereby further reducing the contact probability between the steam and the panel after flowing out.

[0040] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Embodiment 1

[0042] This embodiment provides a steam valve, as Figure 1 shown, including:

[0043] The steam valve body is internally provided with a steam passage 3;

[0044] The steam passage 3 is provided with a steam inlet and a steam outlet disposed opposite to the steam inlet, and the steam outlet is disposed closer to the center of the steam passage 3 relative to the steam inlet.

[0045] As Figure 1 shown, the steam inlet is disposed at a lower position of the steam outlet.

[0046] Specifically, the center of the steam passage can be regarded as the longitudinal axis of the steam passage, and the steam outlet converges closer to the longitudinal axis relative to the steam inlet. In this embodiment, the shapes of the steam inlet and the steam outlet are not limited, and they can be regular shapes such as oval, rectangular, etc., or irregular shapes. As an implementation manner, the steam outlet and the steam inlet can be circularly arranged. At this time, the inner diameter of the steam outlet will be smaller than the inner diameter of the steam inlet. For example, the inner diameter of the steam outlet is set to 3 cm, and the inner diameter of the corresponding steam inlet is set to 5 cm.

[0047] In this embodiment, the steam valve can control whether steam can flow out to the outside through the lid of the cooking equipment. When the steam valve is opened, steam enters the inside of the steam valve seat 11, as Figure 5 shown in area A in, and then further flows out of the lid of the cooking equipment through the steam passage 3 on the steam valve 2.

[0048] As Figure 1 and Figure 2 shown in the perspective view, the steam inlet is disposed below the steam passage, and the steam outlet is disposed above the steam passage. The steam flowing out through the steam valve seat 11 can further flow to the steam valve 2 and flow out to the outside through the steam passage 3 provided on the steam valve 2, sequentially through the steam inlet and the steam outlet;

[0049] By defining that the steam outlet is disposed closer to the center of the steam passage relative to the steam inlet, it can play a guiding role for the high-temperature steam itself, and the high-temperature steam can gather toward the center direction of the steam passage, thereby effectively avoiding the steam from overflowing outwardly after flowing out of the steam passage.

[0050] In this embodiment, as Figure 1 shown, the steam valve 2 includes:

[0051] A steam upper cover 21; a steam lower cover 22 disposed on one side of the steam upper cover 21 close to the main body 1. As Figure 1 shown, the steam lower cover 22 is disposed below the steam upper cover 21, and at least a part of the steam lower cover 22 is provided with a guiding portion 221, and the guiding portion forms the steam passage 3.

[0052] Specifically, in this embodiment, the shape of the guiding part 221 itself is not limited. It can be arranged in a straight line or in a wavy line. As a preferred embodiment, the guiding part 221 is arranged in an arc shape, as long as the inner diameter of the steam inlet on the guiding part 221 is larger than the inner diameter of the steam outlet. As an embodiment, the guiding part 221 itself can be arranged in a shape similar to a hyperbola. Preferably, as Figure 1 shown, from bottom to top in the height direction, the inner diameter of the guiding part 221 gradually decreases. Through the above setting method, the guiding part 221 gradually converges the steam inside it, which helps to converge the steam into a limited area, thereby preventing the steam from overflowing outward after flowing out of the steam channel.

[0053] In this embodiment, the steam upper cover 21 and the steam lower cover 22 are connected by a buckle, so as to form the steam valve 2 as a whole. As Figure 1 shown, the steam upper cover 21 is arranged above the steam lower cover 22.

[0054] In this embodiment, as Figure 1 shown, it further includes:

[0055] A convex part 5, arranged at one end of the steam valve 2 far from the main body 1, and the convex part 5 at least partially surrounds the steam channel 3.

[0056] As Figure 1 shown, the convex part 5 is arranged upward. In this embodiment, the shape of the convex part 5 itself is not limited. It can be arranged in a ring shape, a circular shape, or an irregular closed shape. As a variant, it can also be arranged in a spaced shape. At the same time, the convex part 5 itself is arranged outside the outer circumference of the steam channel 3, and its function is similar to that of a city wall, which can block at least a part of the steam.

[0057] By restricting the flow direction of the high-temperature steam through the convex part 5, it is possible to prevent the steam from overflowing around after flowing out of the steam channel 3, thereby avoiding thermal burns to the surrounding operators caused by the high-temperature steam. At the same time, it can also prevent the steam from contacting the panel 12 and pre-cooling to form condensate water, which has an adverse impact on the surrounding environment.

[0058] In the steam valve provided in this embodiment, the convex part 5 includes:

[0059] A connecting part 51, one end of which extends to the steam channel 3;

[0060] A convex platform 52, connected to the connecting part 51, and the height of the convex platform 52 is higher than the height of the connecting part 51.

[0061] By providing the connection portion 51, a certain buffer area can be formed on the raised portion 5 to prevent the high-temperature steam flowing out of the steam channel 3 from quickly escaping to the surroundings of the steam channel 3, thereby preventing the high-temperature steam from escaping to the surroundings. Specifically, the connection portion 51 itself can be arranged horizontally or at a certain angle, such as the end of the connection portion 51 away from the steam channel 3 is arranged upward.

[0062] Furthermore, in the steam valve provided in this embodiment, the boss 52 is arranged in an inclined shape at one end close to the connecting portion 51. Since the boss itself is arranged in an inclined shape, when the high-temperature steam moves to the boss position, it can be guided by the boss to change from a diffuse shape to a convergent shape, thereby further reducing the probability of contact between the steam and the panel after it flows out.

[0063] like Figure 1 and Figure 5 As shown, after the high-temperature steam gathered by the guide portion 221 flows out from the steam channel 3, it will further diffuse to the connecting portion 51. After being buffered by the connecting portion 51, it will be blocked by the boss 52. Through the above structure, the flow rate and diffusion area of ​​the high-temperature steam itself can be effectively slowed down, thereby effectively preventing the high-temperature steam from overflowing to the surroundings.

[0064] In this embodiment, Figure 1 As shown, it also includes: a baffle 4, which is arranged on the steam valve 2 and is suitable for moving relative to the steam valve seat 11. Specifically, the shape of the baffle 4 itself is not limited. As an embodiment, the baffle 4 can be arranged horizontally. Preferably, the outer edge of the baffle is inclined toward the steam valve seat, such as Figure 1 As shown, the outer edge of the baffle is inclined downward, and the baffle 4 itself can be set in a plate shape or in an inverted bowl shape. Through the above-mentioned setting method, the steam itself can be effectively guided, so as to effectively control the steam to flow out from the predetermined direction to the position of the guide part 221, and continue to rise along the guide part 221, so as to effectively control the flow rate and diffusion area of ​​the high-temperature steam itself in the later stage.

[0065] In this embodiment, as an implementation method, the size of the baffle 4 is larger than the size of the corresponding part of the steam valve seat 11. Through the above-mentioned setting method, the baffle 4 itself can block the steam valve seat 11, thereby preventing high-temperature steam from overflowing from the steam valve seat 11 during certain cooking stages. As another implementation method, the size of the baffle 4 is slightly smaller than the size of the corresponding part of the steam valve seat 11, and a slight pressure can be formed at this time to facilitate cooking operations.

[0066] When the steam pressure in the pot body is too high or when it is necessary to actively relieve the pressure and exchange heat of the pot body, the steam valve 2 will be disengaged from the steam valve seat 11, so that the steam will enter the outside through the steam valve seat 11. In this embodiment, the baffle 4 is made of a material with a certain flexibility, such as high-temperature resistant plastic, etc. As a variant, it can also be made of a hard material, which is not limited in this embodiment.

[0067] The cooking equipment cover body provided in this embodiment, such as Figure 3 shown, a plurality of ribs 6 are provided between the baffle 4 and the steam lower cover 22. By providing the ribs 6, the baffle 4 can be connected to the guiding portion 221. By providing the ribs, first, the connection strength between the guiding portion 221 and the baffle 4 can be improved. Further, the steam passage 3 can be divided into multiple parts, so as to effectively shunt the steam.

[0068] Embodiment 2

[0069] The cooking equipment cover body provided in this embodiment, such as Figures 2 - 5 shown, in this embodiment, the cooking equipment cover body can be used on an electric pressure cooker, or on a rice cooker, or on an electric appliance such as a steam box, a steam oven or a steam iron that realizes its basic functions through steam. In this embodiment, the cooking equipment cover body includes:

[0070] A main body 1, on which a steam valve seat 11 for steam to flow out is provided;

[0071] In this embodiment, a panel 12 is provided on the main body 1. The panel 12 itself is a structure that directly contacts the user. When the high-temperature steam flowing out through the steam valve encounters the panel 12, it will condense, and then form condensed water. In this embodiment, the panel 12 is made of a plastic material.

[0072] The steam valve seat 11 is used to introduce the high-temperature steam generated by the pot body into the interior of the cooking equipment cover body. The steam valve seat 11 is provided in a vertically penetrating shape, and an air inlet hole 111 is provided on the steam valve seat 11.

[0073] The steam valve 2 provided in Embodiment 1 is provided on the main body 1. A steam passage 3 communicating with the steam valve seat 11 is provided on the steam valve 2. The steam passage 3 is provided with a steam inlet close to the steam valve seat 11 and a steam outlet far from the steam valve seat 11. The steam outlet is closer to the center of the steam passage than the steam inlet.

[0074] The cooking equipment cover body provided in this embodiment further includes: a driving device provided on the main body 1, and the movable end of the driving device is provided on the steam valve 2 for controlling the lifting of the steam valve 2.

[0075] Specifically, by controlling the opening, closing, and the degree of opening or closing of the steam valve 2, the steam pressure and temperature inside the pot body can be effectively adjusted, which helps to ensure the quality of the finally obtained food. Specifically, in this embodiment, the driving device itself can be set as a motor, the fixed end of the motor is arranged on the main body 1, and the movable end is arranged on the steam valve 2.

[0076] As Figure 1 shown, a handle 7 is arranged on the steam valve 2, and the steam valve 2 can be separated from the main body 1 through the handle 7, thereby improving the operation convenience of the user.

[0077] Embodiment 3

[0078] This embodiment provides a steaming device, including:

[0079] The steaming device lid provided in Embodiment 2;

[0080] Specifically, the shape of the steaming device lid itself is not limited, and it can be in regular shapes such as circular, oval, etc., as long as it can achieve the sealing effect on the pot body itself.

[0081] A pot body, the steaming device lid is arranged on the pot body, and a water storage part is arranged inside the pot body. The inside of the water storage part can be used to place the water that needs to generate steam. After the water is heated to generate steam, it will further rise and flow to the steam valve seat of the steaming device lid, and after passing through the steam valve, it will contact the convex part, thereby effectively preventing the high-temperature steam from overflowing to the surroundings.

[0082] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
