In a first embodiment of the present disclosure:

as shown in fig. 1 and 2, the cooking device of the present embodiment mainly includes a heat insulating cover 1, a pot lid 2, a lid body 3, and a first gasket 4 as a sealing member. Wherein, a cavity (not marked in the figure) for accommodating the pot container 2 is formed on the heat-preservation outer cover 1; the boiler liner 2 can be mounted on the heat preservation outer cover 1 and can be taken out of the heat preservation outer cover 1. The cover body 3 can be buckled on the pot container 2 and accordingly covers the pot container 2, and the cover body 3 can be taken down from the pot container 2. The first sealing ring 4 is arranged between the pot container 2 and the cover body 3 and can be clamped by the turned-over edges of the heat-insulating outer cover 1 and the pot container 2, so that a heat-insulating cavity 5 is formed between the heat-insulating outer cover 1 and the pot container 2.

With reference to fig. 1 and 2, the bottom of the heat-insulating outer cover 1 is provided with an air hole 11, the air hole 11 penetrates through the side wall of the heat-insulating outer cover 1, and the diameter of the air hole 11 is smaller than or equal to 1mm, so that the air hole 11 is as small as possible on the premise of ensuring the air permeability of the air hole 11. In addition, a person skilled in the art can also arrange the ventilation holes 11 in the middle or upper part of the heat-insulating outer cover 1 according to the requirement, but the aesthetic property is poor compared with the arrangement of the ventilation holes 11 in the bottom of the heat-insulating outer cover 1.

With continued reference to fig. 1 and 2, the flange of the pot core 2 overlaps the top edge of the insulating cover 1 in the up-down direction shown in fig. 1.

With continued reference to fig. 1 and 2, the cover 3 is provided with an air inlet 31, an air duct 32 and a cover sealing ring 33. Wherein, the air inlet 31 is positioned at the outer side of the cover body 3, and the air duct 32 is positioned at the inner side of the cover body 3 and is communicated with the air inlet 31. The lid sealing ring 33 is provided on the inner side of the lid 3 so as to be capable of being brought into contact with the pot lid 2 in a sealed manner when the lid 3 is fastened to the pot lid 2 (as shown in fig. 3).

As shown in fig. 2, in a state where the lid body 3 is fastened to the inner pot 2, the air duct 32 is inserted into the inner pot 2 so that the air duct 32 can guide the high-temperature steam received from the air inlet 31 into the inner pot 2 to heat the food in the inner pot 2.

With continued reference to fig. 1 and 2, the first sealing ring 4 is provided with a first annular groove 41, and the opening of the first annular groove 41 faces downward as viewed in fig. 1 and 2, so that the first sealing ring 4 is fitted over the top edge of the heat insulating housing 1 through the first annular groove 41 as viewed in fig. 2. As can be seen from fig. 1 and 2, the cross section of the first sealing ring 4 perpendicular to the extending direction is in an inverted U shape, so that the first sealing ring 4 can clamp the top edge of the heat-insulating housing 1 through two side edges of the inverted U shape, and the first sealing ring 4 and the heat-insulating housing 1 are firmly fixed together. Preferably, the first sealing ring 4 is made of rubber material, so as to increase the friction force between the first sealing ring 4 and the heat-insulating housing 1 and improve the sealing effect of the first sealing ring 4. In addition, a person skilled in the art may also set the first sealing ring 4 as a member made of any other feasible material, such as silicone, flexible plastic, etc., on the premise that the first sealing ring 4 can achieve the two aforementioned effects, as required.

As shown in fig. 2 and 3, when the pot core 2 is placed in the cavity of the heat-insulating outer cover 1, the flange of the pot core 2 and the top of the first sealing ring 4 are in sealing contact with each other.

It should be noted that, in order to better express the situation that the lid 3 is in sealing contact with the boiler inner container 2 through the lid sealing ring 33, and the situation that the boiler inner container 2 is in sealing contact with the first sealing ring 4, in fig. 2 and 3, the lid sealing ring 33, the boiler inner container 2 and the first sealing ring 4 are drawn by mutually interfering drawings, thereby facilitating the understanding of the technical solutions of the present embodiment by those skilled in the art.

With continued reference to fig. 1 and 2, the cooking device of the present embodiment further includes a first heating device 6 disposed at the bottom of the heat-retaining cover 1, wherein the first heating device 6 is used for heating the gas in the heat-retaining chamber 5. It can be understood by those skilled in the art that the first heating device 6 is disposed at the bottom of the heat-insulating housing 1 because the cold air will sink and the hot air will float, so that the cold air in the heat-insulating chamber 5 will be heated by the first heating device 6 in time, and the heat distribution of the air in the heat-insulating chamber 5 is relatively uniform.

The principle of keeping the temperature of the cooking appliance of the present embodiment is briefly described below with reference to fig. 2 and 3.

Firstly, the cooking utensil is installed as shown in figure 2, so that the pot container 2 is hermetically connected with the heat-preservation outer cover 1 through the first sealing ring 4 to form a heat-preservation cavity 5; the cover body 3 is hermetically abutted with the pot container 2 through a cover body sealing ring 33.

Then, the first heating means 6 is operated to heat the gas in the soak chamber 5. In the process, the air heated by the first heating device 6 floats to the top of the holding chamber 5, and the cold air is gathered to the bottom of the holding chamber 5 and is heated by the first heating device 6. And because the air can expand after heating, the air in the heat preservation cavity 5 can flow to the outside from the air holes 11, thereby reducing the density of the air in the heat preservation cavity 5, and because the density is reduced, the heat conduction capability of the air in the heat preservation cavity 5 can be reduced, thereby enabling the heat preservation cavity 5 to have the heat preservation function.

As can be understood by those skilled in the art, during the process that the air in the heat preservation chamber 5 is heated, the cold air in the heat preservation chamber 5 can be discharged from the air holes 11, and the hot air can be retained in the heat preservation chamber, so that the waste of energy is avoided.

Based on the foregoing description, it can be understood by those skilled in the art that the cooking device of the present embodiment not only enables the pot core 2 to be detached alone, but also enables the air in the heat preservation cavity 5 to be heated by the first heating device 6 after the pot core 2 is installed on the heat preservation outer cover 1, so that the air in the heat preservation cavity 5 flows to the outside, so that the heat preservation cavity 5 forms a structure similar to a vacuum heat preservation layer, and plays a heat preservation role in the pot core 2.

The technical personnel in the field can also understand that, in the process that the food material in the pot container 2 is heated, the food material can be heated and rolled, the rolled food material reacts on the pot container 2 to cause the pot container 2 to vibrate, and the first sealing ring 4 between the heat-insulating outer cover 1 and the pot container 2 can inhibit the vibration of the pot container 2 to achieve the effect of shock absorption.

In a second embodiment of the disclosure:

as shown in fig. 4 to 6, unlike the first embodiment, the present embodiment omits the first seal ring 6 and adds the second seal ring 7. The second sealing ring 7 is provided with a second annular groove 71, the opening of the second annular groove 71 facing the inside of the second sealing ring 7, so that the second sealing ring 7 is fitted over the annular edge of the cooking utensil 2 via the second annular groove 71 as shown in fig. 5 and 6. As can be seen in fig. 6, the cross section of the second sealing ring 7 perpendicular to the extension direction is "C" shaped, so that the second sealing ring 7 can clamp the annular edge of the cooking utensil 2 through the two sides of the "C" shape, and the second sealing ring 7 and the cooking utensil 2 are firmly fixed together. Preferably, the second sealing ring 7 is made of rubber material, so as to increase the friction between the second sealing ring 7 and the cooking utensil 2 and improve the sealing effect of the second sealing ring 7. In addition, a person skilled in the art may also set the second sealing ring 7 as a member made of any other feasible material, such as silicone, flexible plastic, etc., on the premise that the second sealing ring 7 can achieve the two aforementioned effects, as required.

In a third embodiment of the present disclosure:

although not shown in the drawings, the present embodiment is different from the first embodiment in that a second sealing ring 7 is added to the first embodiment, and the first sealing ring 4 and the second sealing ring 7 are abutted together in a state where the pot core 2 is mounted in the heat insulating cover 1.

In a fourth embodiment of the disclosure:

although not shown in the drawings, the present embodiment adds a check valve and an operating member to the first, second, or third embodiment. The check valve is provided on a side wall of the insulating cover 1 and is configured to be opened when a pressure inside the insulating cover 1 is greater than a pressure outside the insulating cover 2, and thus to allow gas inside the insulating cover 1 to flow out from the vent hole 11 to the outside of the insulating cover 1. The operating member is drivingly connected to the check valve and is configured to open the check valve so that the air outside the heat insulating cover 1 flows into the inside of the heat insulating cover 1 through the air holes 11. Illustratively, the one-way valve is an elastic piece attached to the outer sidewall of the insulating cover 1 and capable of covering the airing hole 11, and the operating member is a pull ring fixedly connected to the elastic piece.

As can be understood by those skilled in the art, the cooking appliance of the present embodiment can ensure that the air in the heat preservation chamber 5 flows to the outside, and can prevent the outside air from entering the heat preservation chamber 5 during the operation of the cooking appliance and affecting the heat preservation effect of the heat preservation chamber 5. The cooking utensil of the embodiment can open the one-way valve through the operating component, so that air in the outside can enter the heat preservation cavity 5, the vacuum state of the heat preservation cavity 5 formed by cooling the air in the heat preservation cavity is broken, and a user can take the pot container 2 down without resistance. It will be understood by those skilled in the art that if the insulating chamber 5 is in a vacuum state, the external atmospheric pressure will apply a force to the boiler inner 2 to be closely attached to the insulating outer cover 1, and it is difficult for the user to remove the boiler inner 2 from the insulating outer cover 1.

Further, although not shown in the drawings, the cooking appliances of the first, second, third and fourth embodiments each further include a water storage tank and a second heating device capable of heating liquid water from the water storage tank into steam, and the lid 3 (specifically, the air inlet 31) is capable of receiving the steam and delivering the steam into the boiler liner 2.

It can be understood by those skilled in the art that the water storage tank and the second heating device may be fixedly connected to the heat-insulating cover 1, or may be provided separately from the heat-insulating cover 1 (e.g., a steam heating type electric rice cooker disclosed in chinese patent publication No. CN 209284978U).

So far, the technical solutions of the present disclosure have been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present disclosure is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined, and equivalent changes or substitutions can be made on related technical features by those skilled in the art without departing from the technical principles of the present disclosure, and any changes, equivalents, improvements, and the like made within the technical concept and/or technical principles of the present disclosure will fall within the protection scope of the present disclosure.
