According to the utility model discloses cooking utensil 100, the steam that steam generating device 20 generated can flow into lid 30 through air inlet pipe 31 to further through one-way inflow cooking chamber 101 of check valve subassembly 40, thereby can prevent to eat the material and the problem that the material appears backflowing and noise air inlet pipe 31 blocks up or pollutes air inlet pipe 31 takes place, promotes cooking utensil 100's safety in utilization, reliability. Meanwhile, high-temperature steam is sprayed to the cooking cavity 101 through the steam nozzle 46, so that the high-temperature steam has certain impact force when entering the cooking cavity 101, the high-temperature steam can be fully contacted with food materials, and the cooking effect of the cooking appliance 100 on the food materials is improved.

As shown in fig. 3 and 5, in some embodiments of the present invention, the check valve assembly 40 includes: an upper cover 41, a lower cover 42 and a valve core assembly 43.

Referring to fig. 7, the upper cover 41 is provided with a first passage 411, the first passage 411 is communicated with the air intake duct 31, the lower cover 42 is connected with the upper cover 41, and the lower cover 42 is provided with a second passage 421 communicated with the first passage 411, the lower cover 42 extends in a vertical direction, and at least a portion of the lower cover 42 penetrates the cover body 30 and extends into the cooking chamber 101.

As shown in fig. 2, the valve core assembly 43 is installed at the lower cover 42, and the valve core assembly 43 can selectively communicate the first passage 411 with the second passage 421. When the first passage 411 is communicated with the second passage 421, the high temperature steam in the first passage 411 may flow into the second passage 421 and further be delivered to the side of the cooking chamber 101 through the second passage 421; when high-temperature steam does not need to be delivered to the cooking cavity 101, the steam generating device 20 does not operate, and the first passage 411 and the second passage 421 are not communicated, so that even if the cooking appliance 100 is in a cooking condition (i.e., the temperature in the cooking cavity 101 is high), the ingredients in the cooking cavity 101 cannot flow into the air inlet pipeline 31 through the check valve assembly 40.

As shown in fig. 3, in some embodiments of the present invention, the second channel 421 includes a mounting section in which the valve core assembly 43 is disposed.

As shown in fig. 2 and 3, the spool assembly 43 includes: the valve core rod 431 is movably arranged in the installation section, the valve core rod cap 432 is arranged at the end part of the valve core rod 431, the valve core rod cap 432 can seal the port of the first channel 411 communicated with the second channel 421, and the elastic piece 433 is elastically supported between the valve core rod 431 and the wall surface of the second channel 421.

Referring to fig. 2, the lower cover 42 is configured as a hollow structure, the second channel 421 is formed at the hollow structure, and the second channel 421 includes a mounting section for mounting and receiving the valve core assembly 43 and an air outlet section.

As shown in fig. 2, the mounting section includes a first section 4211, a second section 4212 and a third section 4213 which are sequentially communicated in a vertical direction, the third section 4213 is communicated with the air outlet section, and the radial dimensions of the first section 4211, the second section 4212, the third section 4213 and the air outlet section are gradually decreased, so that a stepped structure is formed at the mounting section, and the elastic member 433 can be supported on a stepped surface of the third section 4213 to vertically support the valve core rod 431 through the elastic member 433, and drive the valve core rod cap 432 to a position suitable for blocking the first channel 411.

Specifically, the spool rod 431 includes a rod portion 4312 and a flange 4313, the flange 4313 is protruded from the rod portion 4312 in a radial direction, and the elastic member 433 is sleeved on the rod portion 4312 and supported between the stepped surface and the flange 4313. When the valve core rod 431 moves downwards under the driving of high-temperature steam, the flange 4313 compresses the elastic piece 433; when the high-temperature steam no longer applies driving force to the spool rod 431 or the driving force is reduced, the elastic member 433 drives the spool rod 431 to move upwards to block the port of the first channel 411, which is communicated with the second channel 421, through the spool rod cap 432.

It can be understood that, as shown in fig. 2, the valve core rod 431 moves in the vertical direction in the mounting section, and by configuring the mounting section into a three-stage stepped structure, the second stage 4212 can avoid the flange 4313 when moving downwards, and the third stage 4213 can avoid the rod 4312 when moving downwards, so as to prevent the valve core rod 431 from interfering with the wall surface of the second channel 421.

Meanwhile, the second channel 421 is configured such that the cross section decreases from the upstream (the end where the second channel 421 communicates with the first channel 411) to the downstream (the end where the second channel 421 communicates with the steam spout 46), so that the pressure of the steam on the downstream side in the second channel 421 is greater, the flow speed of the steam increases as the cross-sectional dimension of the flow path decreases, and thus the flow speed of the steam sprayed from the steam spout 46 can be increased, the steam is discharged with a certain impact force, and the steam is in full contact with the food material, thereby improving the cooking effect.

In some embodiments of the present invention, the spool stem cap 432 is configured as a ball head, and when the spool stem cap 432 closes the port of the first passage 411, at least a portion of the spool stem cap 432 extends into the first passage 411 to block the first passage 411 by the spool stem cap 432.

The valve core rod cap 432 is provided with an annular inclined surface, the annular inclined surface is suitable for being matched with a port of the first channel 411 in an abutting mode, the valve core rod cap 432 has a sealing effect, abrasion of the valve core rod cap 432 when matched with the port in a sealing mode can be reduced, and the service life of the valve core rod cap 432 is prolonged.

As shown in fig. 5, in some embodiments of the present invention, the valve core rod 431 is provided with a groove 4311, the groove 4311 is recessed downwards from the upper end of the valve core rod 431 and is opened upwards, and the opening of the groove 4311 is opposite to the air outlet port of the first channel 411. The valve core rod 431 assembly further includes a seal 48, the seal 48 is disposed in the groove 4311 and the air outlet of the first channel 411 is disposed opposite, and at least a portion of the seal 48 protrudes out of the groove 4311, such that the seal 48 can be press-fitted with the upper cover 41. Referring to fig. 4, the sealing gasket 48 may be in abutting engagement with the upper cover 41 to block the first passage 411.

Referring to fig. 4 and 5, the gasket 48 is mounted in the groove 4311, the gasket 48 may be configured as a rubber member or the like having good sealing performance, and the gasket 48 is in interference fit with the groove 4311 to improve the connection reliability of the gasket 48 with the spool rod 431 and prevent the gasket 48 from being removed from the groove 4311.

It will be appreciated that the seal 48 may also be directly connected to the end of the valve plug rod 431, i.e., without the groove 4311, and the seal 48 may move synchronously with the valve plug rod 431 within the second channel 421.

As shown in fig. 3 and 5, in some embodiments of the present invention, the elastic member 433 is configured as a spring, and a spring force value of the spring is less than 4kpa. After steam generation device 20 stops to generate steam, still have the exhaust steam blowout, when the spring force value of spring satisfied above-mentioned parameter range, can make exhaust steam discharge fast, avoid discharging again after lid 30 opens, promote cooking utensil 100's security.

It can be understood that the driving force of the valve core assembly 43 for communicating the first channel 411 and the second channel 421 is provided by steam, and due to the large thermal inertia of the steam generating device 20, when the steam generating device 20 finishes cooking, residual heat steam exists in the air inlet pipeline 31, the residual heat steam still drives the valve core rod 431 to move downwards, and at this time, the first channel 411 and the second channel 421 keep communicating, and the residual heat steam can be exhausted out of the cover 30 through the check valve assembly 40. Therefore, the spring force value of the spring is not too large, so that the waste heat steam of the air inlet pipeline 31 can be discharged quickly.

It should be noted that the spring force value of the spring needs to be greater than the gravity of the spool rod 431 and the spool rod cap 432 (or the spool rod 431 and the gasket) to ensure the supporting effect of the spring on the spool rod 431.

As shown in fig. 7 and 8, in some embodiments of the present invention, the check valve assembly 40 further includes an end cap 44, the end cap 44 is connected to the lower cap 42, and the end cap 44 is formed with a steam spout 46, the steam spout 46 communicating with the second channel 421.

Referring to fig. 7, when steam is discharged from the lower cover 42, it enters a space defined between the end cap 44 and the lower cover 42, and the steam may be discharged into the cooking chamber 101 through the steam vents 46.

Wherein the end cap 44 is removably coupled to the lower cap 42 such that the end cap 44 may be cleaned or replaced.

It can be understood that when the steam generating device 20 does not generate steam any more, the food or steam in the cooking cavity 101 can enter the second channel 421 through the steam spout 46, but since the valve core assembly 43 seals the first channel 411, the food or steam cannot enter the first channel 411, but the food or steam can adhere to the inner wall of the end cover 44, so that the end cover 44 needs to be cleaned or replaced.

Referring to fig. 7, the lower end of the lower cover 42 is opened, and the opened end of the lower cover 42 is spaced apart from the bottom wall of the end cover 44 to reserve a space for steam to flow between the lower cover 42 and the end cover 44. Wherein the steam vents 46 are formed on the bottom wall of the end cap 44, and the extending direction of the steam vents 46 is inclined to the central axis of the lower cover 42, so that steam or water can be uniformly sprayed toward the food material in the cooking cavity 101.

In some embodiments of the present invention, the lower cover 42 is formed with the steam nozzle 46 at the portion inside the cooking cavity 101, the steam nozzle 46 is communicated with the second channel 421, and the high temperature steam can be sprayed to the cooking cavity 101 through the steam nozzle 46.

As shown in fig. 3 and 5, the steam vent 46 is integrated on the lower cover 42, and by forming the steam vent 46 by opening a hole on the lower cover 42, the structure is simple and the steam delivery effect to the cooking chamber 101 can be improved. Wherein, the cross-sectional dimension of the steam nozzle 46 in the extending direction is smaller than the cross-sectional dimension of the air outlet section at any position in the axial direction, so that the steam discharging effect can be ensured.

It will be appreciated that when the vapor vent 46 is integrated into the lower cover 42, the number of parts in the check valve assembly 40 can be reduced, reducing costs, without the need for separately providing the components used to form the vapor vent 46 (such as the end cap 44 described above).
