Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a regulating valve and a cooking appliance. Background Technology

[0002] The cooking utensil consists of a base and a pot body, with the pot body located on the base and used for stewing food.

[0003] In related technologies, the pot body is equipped with a regulating valve, which has a vent hole for regulating the steam pressure inside the pot. However, in these technologies, water droplets generated by the liquefaction of steam inside the pot can easily clog the vent hole of the regulating valve, leading to excessive steam pressure inside the pot and posing a safety risk. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a regulating valve and a cooking appliance having the regulating valve, which can reduce the risk of spillage and ensure high safety.

[0005] The regulating valve of this utility model embodiment includes a valve body and a valve seat. The valve seat is provided with an air inlet. At least a portion of the valve body is disposed within the valve seat. The valve body is provided with a first air outlet and a second air outlet arranged at intervals.

[0006] The regulating valve further includes a supplementary airflow channel, the first air outlet is connected to the air inlet, and the second air outlet is connected to the air inlet through the supplementary airflow channel.

[0007] In this embodiment of the regulating valve, the first vent is connected to the vent. When the regulating valve is applied to a cooking appliance, steam inside the pot can be discharged through the vent and the first vent to adjust the steam pressure inside the pot. Furthermore, the second vent is connected to the vent through a supplementary airflow channel. Even if water droplets generated by steam liquefaction block the first vent, steam inside the pot can still be discharged through the vent, the supplementary airflow channel, and the second vent, ensuring timely discharge of steam from the pot. Therefore, the regulating valve of this embodiment has good exhaust performance. When applied to a cooking appliance, it can reduce the risk of excessive pressure inside the pot and overflow caused by the lid being pushed open by steam, thus improving safety during use.

[0008] Optionally, the bottom of the valve body is provided with a protrusion, which abuts against the valve seat to separate the valve body and the valve seat, and the gap between the valve body and the valve seat forms the supplementary airflow channel.

[0009] The regulating valve of this utility model has a simple structure and is easy to manufacture because it sets a protrusion to separate the valve body and the valve seat to form a supplementary airflow channel.

[0010] Optionally, the valve seat includes a mating portion that abuts against the bottom surface of the valve body, the air inlet extends from the bottom surface of the valve seat to the mating portion, the valve seat is an elastic element, and when the pressure at the mating portion increases to a preset pressure, the supplementary airflow channel can be formed between the mating portion and the valve body.

[0011] In this embodiment of the utility model, the regulating valve has an air inlet extending from the bottom surface of the valve seat to the mating part, facilitating communication between the air inlet and the first air outlet. The valve seat is an elastic element. When the steam pressure at the mating part increases, the steam can push the valve body away from the valve seat to form a supplementary airflow channel between the valve body and the mating part. This can improve the reliability of exhaust and ensure that the steam pressure inside the pot reaches a preset level so that the steam pressure at the mating part increases. Only then can the steam inside the pot be discharged through the supplementary airflow channel, reducing the risk of overflow while ensuring cooking efficiency.

[0012] Optionally, there are multiple protrusions, and the multiple protrusions are arranged at intervals along the circumference of the valve body.

[0013] The regulating valve of this utility model has multiple protrusions arranged at intervals along the circumference of the valve body, which can further ensure that a gap is formed between the bottom surface of the valve body and the valve seat, which is sufficient to allow steam in the air inlet to flow into the second air outlet, thereby reducing the risk of overflow.

[0014] Optionally, the valve body includes an outer ring, an inner ring, and a connector. The inner ring is located inside the outer ring and is spaced apart from the outer ring to form an annular space. At least a portion of the annular space forms the second vent hole. The inner ring surrounds the first vent hole. The connector connects the inner ring and the outer ring.

[0015] The regulating valve of this utility model has a simple valve body structure, which saves manufacturing costs. Moreover, the formation of the first and second air outlets is simple and easy to manufacture.

[0016] Optionally, the connector is located within the annular space, and there are multiple connectors arranged at circumferential intervals along the outer ring, with the second air outlet formed between adjacent connectors.

[0017] In this embodiment of the utility model, the regulating valve has an outer ring and an inner ring connected by multiple connectors, which makes the connection between the outer ring and the inner ring firm and ensures the stability of the valve body structure.

[0018] Optionally, the regulating valve further includes a flow guide portion disposed radially outside the first air outlet and / or the second air outlet, the flow guide portion including an outwardly extending and upwardly inclined surface.

[0019] In this embodiment of the regulating valve, when steam is discharged through the first vent and / or the second vent and liquefies into water droplets upon cooling, a guide portion is provided on the radially outer side of the first vent and / or the second vent to allow the water droplets adhering to the inclined surface to flow back, preventing water from overflowing.

[0020] Optionally, multiple inclined surfaces are provided, and the multiple inclined surfaces are arranged sequentially along the circumferential direction.

[0021] The regulating valve of this utility model can effectively prevent water overflow and improve water return efficiency by setting multiple inclined surfaces along the circumference.

[0022] Optionally, the top of the valve seat has a groove that communicates with the air inlet, and the valve body is detachably fitted into the groove.

[0023] The regulating valve of this utility model has a valve body fitted in a groove. The valve body and valve seat are fitted in a simple way, and the valve body and valve seat are detachably connected, which makes it easy to disassemble and clean and easy to install.

[0024] Optionally, the valve seat is made of silicone, the valve body is made of plastic, one of the outer peripheral surface of the valve body and the inner peripheral surface of the valve seat is provided with a supporting rib, and the other of the outer peripheral surface of the valve body and the inner peripheral surface of the valve seat is provided with a mating groove, and the supporting rib and the mating groove are fitted together.

[0025] The regulating valve of this utility model embodiment has a silicone valve seat and a plastic valve body. The valve seat and valve body save costs. The valve body is set in a groove to support the valve seat. The valve body and valve seat are connected by support ribs and mating grooves to ensure that the valve body and valve seat can be detachably connected. The structure is simple and strong.

[0026] Optionally, the cross-sectional area of ​​the air inlet is larger than the cross-sectional area of ​​the first air outlet.

[0027] The regulating valve of this utility model embodiment, through the above-mentioned settings, ensures that the amount of steam vented through the first vent is less than the amount of steam generated in the containment cavity, so that steam accumulates in the containment cavity, maintains a certain pressure, and ensures the cooking efficiency of the pot for food.

[0028] Optionally, the first vent is a circular hole with a diameter of 3mm-5mm.

[0029] The regulating valve of this utility model embodiment, by limiting the diameter of the first vent hole, can prevent excessive steam from being released from the containment cavity, allowing steam to accumulate in the containment cavity and ensuring the cooking efficiency of the pot for food.

[0030] The cooking appliance of this utility model embodiment includes:

[0031] A pot body having a receiving cavity, the upper end of which has an opening;

Detailed Implementation

[0042] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] This utility model embodiment proposes a regulating valve and a cooking appliance having a regulating valve. The regulating valve of this utility model embodiment is described first below.

[0044] like Figures 1-6 As shown, the regulating valve of this embodiment includes a valve body 31 and a valve seat 32. The valve seat 32 is provided with an air inlet 321. At least a portion of the valve body 31 is disposed within the valve seat 32. The valve body 31 is provided with a first air outlet 311 and a second air outlet 312 arranged at intervals. The regulating valve 311 also includes a supplementary airflow channel 33. The first air outlet 311 communicates with the air inlet 321, and the second air outlet 312 communicates with the air inlet 321 through the supplementary airflow channel 33.

[0045] In this embodiment of the regulating valve, the first vent 311 is connected to the vent 321. When the regulating valve is applied to a cooking appliance, the steam in the pot 1 can be discharged through the vent 321 and the first vent 311 to adjust the steam pressure in the pot 1. Moreover, the second vent 312 is connected to the vent 321 through the supplementary airflow channel 33. Even if the first vent 311 is blocked by water droplets generated by steam liquefaction, the steam in the pot 1 can still be discharged through the vent 321, the supplementary airflow channel 33, and the second vent 312, ensuring that the steam in the pot 1 is discharged in a timely manner. Therefore, the regulating valve of this embodiment has good exhaust performance. When applied to a cooking appliance, it can reduce the risk of excessive pressure in the pot 1 and the risk of the lid 2 being pushed open by steam, thus improving the safety of use.

[0046] Understandably, during actual cooking, water droplets generated by steam liquefaction may block the first vent 311, leading to excessive steam pressure inside the pot 1. This could cause the lid 2 to be pushed open by the steam, and bubbles to form around the pot 1 or cause overflow. Therefore, by forming a supplementary airflow channel 33 between the bottom surface of the valve body 31 and the valve seat 32, the steam inside the pot 1 can be discharged through the air inlet 321, the supplementary airflow channel 33, and the second vent 312, thus improving safety.

[0047] Specifically, the central axis of the first vent 311 is collinear with the central axis of the vent 321, ensuring the efficiency of steam discharge from the pot body 1 through the first vent 311.

[0048] Optionally, a protrusion 313 is provided at the bottom of the valve body 31, and the protrusion 313 abuts against the valve seat 32 to separate the valve body 31 and the valve seat 32. The gap between the valve body 31 and the valve seat 32 forms a supplementary airflow channel 33.

[0049] Specifically, such as Figure 2 and Figure 5 As shown, the bottom surface of the valve body 31 has a protrusion 313, which is located on the side of the second air outlet 312 away from the first air outlet 311. The protrusion 313 separates the valve body 31 and the valve seat 32 to form a supplementary airflow channel 33, which has a simple structure and is easy to manufacture.

[0050] It is understood that the supplementary airflow channel 33 is not limited to the above-mentioned formation by the protrusion 313 separating the valve body 31 and the valve seat 32. The supplementary airflow channel 33 can also be a tubular channel separately provided at the bottom of the valve body 31 when the valve body 31 is injection molded, or a tubular channel separately provided on the valve seat 32 when the valve seat 32 is manufactured.

[0051] Optionally, the valve seat 32 includes a mating portion 322 that abuts against the bottom surface of the valve body 31. An air inlet 321 extends from the bottom surface of the valve seat 32 to the mating portion 322, facilitating communication between the air inlet 321 and the first air outlet 311. The valve seat 32 is an elastic element. When the pressure at the mating portion 322 increases to a preset pressure, a supplementary airflow channel 33 can be formed between the mating portion 322 and the valve body 31.

[0052] Specifically, such as Figure 5 As shown, the air inlet 321 extends from the bottom surface of the valve seat 32 to the mating part 322, facilitating communication between the air inlet 321 and the first air outlet 311. The mating part 322 is planar. When the valve body 31 is mounted on the valve seat 32, since the valve seat 32 is an elastic element, the protrusion 313 and the bottom surface of the valve body 31, except for the protrusion 313, can all abut against the mating part 322. Therefore, there is no gap between the valve body 31 and the valve seat 32 at the mating part 322. Only when the steam pressure at the mating part 322 increases can the steam push the valve body 31 away from the valve seat 32, forming a supplementary airflow channel 33 between the valve body 31 and the mating part 322. This improves the reliability of exhaust and ensures that the steam pressure inside the pot 1 reaches a preset level, causing the steam pressure at the mating part 322 to increase, so that the steam inside the pot 1 can be discharged through the supplementary airflow channel 33. This reduces the risk of overflow while ensuring cooking efficiency.

[0053] It is understood that the preset pressure refers to the steam pressure at the mating part 322 when it can push the valve body 31 upward relative to the valve seat 32, forming a supplementary airflow channel between the valve body 31 and the mating part 322. The preset pressure can be a specific value determined by those skilled in the art based on the actual structure and material of the valve body 31 and the valve seat 32, as well as the specific actual situation, or it can be a range value, as long as it can form a supplementary airflow channel 33 for steam discharge.

[0054] Optionally, such as Figure 5As shown, there are multiple protrusions 313, which are arranged at intervals along the circumference of the valve body 31. This can further ensure that a gap is formed between the bottom surface of the valve body 31 and the valve seat 32, which is sufficient to allow steam in the air inlet 321 to flow into the second air outlet 312, thereby reducing the risk of overflow.

[0055] Specifically, the protrusion 313 is elongated and includes a first protrusion 3131 and a second protrusion 3132. The first protrusion 3131 and the second protrusion 3132 are opposite to each other and spaced apart. The second vent 312 is located between the first protrusion 3131 and the second protrusion 3132.

[0056] Optionally, such as Figure 4 and Figure 5 As shown, the valve body 31 includes an outer ring 314, an inner ring 315, and a connector 316. The inner ring 315 is located inside the outer ring 314 and is spaced apart from the outer ring 314 to form an annular space 317. At least a portion of the annular space 317 forms a second vent 312. The inner ring 315 surrounds a first vent 311. The connector 316 connects the inner ring 315 and the outer ring 314.

[0057] Specifically, the central axis of the outer ring 314 is collinear with the central axis of the inner ring 315. The valve body 31 has a simple structure, and the formation of the first vent 311 and the second vent 312 is simple and easy to manufacture.

[0058] Optionally, such as Figure 4 and Figure 5 As shown, the connector 316 is located in the annular space 317. There are multiple connectors 316, which are arranged at intervals along the circumference of the outer ring 314. A second vent 312 is formed between adjacent connectors 316.

[0059] Specifically, the outer ring 314 and the inner ring 315 are connected by multiple connectors 316, which makes the connection between the outer ring 314 and the inner ring 315 firm and ensures the stability of the valve body 31 structure. Moreover, the multiple connectors 316 are evenly spaced along the circumference of the outer ring 314, so that the multiple second air outlets 312 are of the same size, thus ensuring the exhaust efficiency of the multiple second air outlets 312.

[0060] Optionally, such as Figure 4 As shown, the regulating valve 3 also includes a flow guide 318, which is disposed radially outside the first air outlet 311 and / or the second air outlet 312. The flow guide 318 includes an outwardly extending and upwardly inclined surface 3181.

[0061] It is understood that, in one embodiment, only the radial outer side of the first vent 311 is provided with a drainage portion 318; in another embodiment, only the radial outer side of the second vent 312 is provided with a drainage portion 318; and in yet another embodiment, both the radial outer side of the first vent 311 and the radial outer side of the second vent 312 are provided with drainage portions 318.

[0062] Specifically, when steam is discharged through the first vent 311 and / or the second vent 312 and liquefies into water droplets upon cooling, the water droplets adhering to the inclined surface 3181 can be allowed to flow back by the drainage part 318, preventing water from overflowing.

[0063] Optionally, such as Figure 4 As shown, multiple inclined surfaces 3181 are provided, and the multiple inclined surfaces 3181 are arranged sequentially along the circumferential direction, which can effectively prevent water from overflowing and improve the water return efficiency.

[0064] Optionally, such as Figure 6 As shown, the top surface of the valve seat 32 has a groove 323, which communicates with the air inlet 321, and the valve body 31 is detachably fitted in the groove 323.

[0065] Specifically, the groove 323 is formed by the top surface of the valve seat 32 being recessed into the bottom surface of the valve seat 32, and the valve body 31 is fitted in the groove 323. The fitting method between the valve body 31 and the valve seat 32 is simple, and the valve body 31 and the valve seat 32 are detachably connected, which can facilitate disassembly and cleaning and easy installation.

[0066] Optionally, the valve seat 32 is made of silicone, the valve body 31 is made of plastic, one of the outer peripheral surface of the valve body 31 and the inner peripheral surface of the valve seat 32 is provided with a support rib 320, and the other of the outer peripheral surface of the valve body 31 and the inner peripheral surface of the valve seat 32 is provided with a mating groove 310, and the support rib 320 and the mating groove 310 are fitted together.

[0067] Specifically, the valve body 31 is disposed in the groove 323 to support the valve seat 32.

[0068] Specifically, such as Figure 2 As shown, the outer circumferential surface of the valve body 31 is provided with an annular mating groove 310, and the inner circumferential surface of the valve seat 32 is provided with an annular support rib 320. When the valve body 31 is installed into the groove 323 of the valve seat 32, the support rib 320 is fitted into the mating groove 310, ensuring that the valve body 31 and the valve seat 32 are detachably connected, with a simple and robust structure.

[0069] It is understandable that the mating groove 310 and the support rib 320 are not limited to annular shapes. The two can cooperate with each other to achieve relative fixation of the valve body 31 and the valve seat 32. In addition, the mating groove can also be provided on the inner circumferential surface of the valve seat 32, and the support rib can be provided on the outer circumferential surface of the valve body 31.

[0070] In one specific embodiment, when the steam pressure at the mating part 322 increases to a preset pressure, since the valve body 31 is a plastic part and the valve seat 32 is a silicone part (the supporting ribs are elastic), the valve body 31 can move upward relative to the valve seat 32 to squeeze the supporting ribs, thereby forming a supplementary airflow channel 33 at the mating part 322 between the valve body 31 and the valve seat 32.

[0071] Optionally, such as Figure 6 As shown, the valve seat 32 includes a seat body 324 and an extension 325. The extension 325 is provided on the bottom surface of the seat body 324, and the groove 323 is provided on the top surface of the seat body 324. The pot lid 2 is provided with a through hole 21, and at least a portion of the extension 325 is fitted into the through hole 21.

[0072] Specifically, when the valve seat 32 is installed on the pot lid 2, the extension 325 is fitted into the through hole 21, making the installation of the valve seat 32 on the pot lid 2 simple.

[0073] Optionally, such as Figure 2 and Figure 6 As shown, the lower end of the extension 325 is provided with a flange 3251. The flange 3251 is located in the receiving cavity 11 and abuts against the inner wall surface of the pot lid 2, ensuring that the valve seat 32 is firmly installed on the pot lid 2.

[0074] Optionally, such as Figure 2 As shown, the cross-sectional area of ​​the air inlet 321 is larger than that of the first air outlet 311, ensuring that the amount of air vented through the first air outlet 311 is less than the amount of steam generated in the accommodating cavity 11, so that steam accumulates in the accommodating cavity 11, which can maintain a certain pressure and ensure the cooking efficiency of the pot body 1 for food.

[0075] Optionally, such as Figure 4 As shown, the first vent 311 is a round hole with a diameter of 3mm-5mm.

[0076] Specifically, the diameter of the first vent 311 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. By limiting the diameter of the first vent 311, excessive steam can be prevented from being discharged from the receiving cavity 11, allowing steam to accumulate in the receiving cavity 11 and ensuring the cooking efficiency of the pot body 1 for food.

[0077] The cooking appliance of this utility model embodiment includes a pot body 1, a pot lid 2, and a regulating valve 3. The pot body 1 has a receiving cavity 11, and the upper end of the receiving cavity 11 has an opening 12. The pot lid 2 is located at the upper end of the pot body 1 to seal the opening 12. The valve seat 32 of the regulating valve 3 is located on the pot lid 2, and the air inlet 321 communicates with the receiving cavity 11.

[0078] In this embodiment of the cooking appliance, the steam in the receiving cavity 11 can be discharged through the regulating valve 3 to adjust the steam pressure in the receiving cavity 11, so that the steam in the receiving cavity 11 can be discharged in time, reducing the risk of overflow caused by excessive pressure in the receiving cavity 11 and the lid 2 being pushed open by steam, and improving the safety of use.
