The structure of the liner 1 according to an exemplary embodiment of the present disclosure will be described in detail with reference to fig. 1 to 8. The inner container 1 is suitable for a cooking appliance heated by an IH method.

Fig. 1 shows a schematic perspective view of a liner 1 according to an exemplary embodiment of the present disclosure. As shown, the liner 1 described herein generally includes a body 10 and a shell 20. The main body 10 defines a space adapted to receive food to be cooked, and a transition portion 14 is provided on a sidewall 12 of the main body 10.

Fig. 2 shows a perspective schematic view of the outer shell 20 of the liner 1 according to an exemplary embodiment of the present disclosure. As shown, the housing 20 has an opening 24. Referring back to fig. 1, the position and size of the opening 24 are designed such that the main body 10 can be partially disposed in the outer case 20 through the opening 24, whereby the main body 10 of the inner container 1 can be partially surrounded by the outer case 20.

Some exemplary implementations of the liner 1 are described below with reference to fig. 3-5. Fig. 3-5 respectively show cross-sectional schematic views of a liner according to various exemplary embodiments of the present disclosure.

As shown in fig. 3, a gap 15 is formed between the main body 10 and the housing 20. The housing 20 includes a flap 26 disposed at the top end 22 of the side 21 thereof, the flap 26 extending inwardly from the side 21 of the housing 20. As shown in fig. 3, the flap 26 is adapted to abut at least a portion of the transition portion 14 of the main body 10, thereby enabling the gap 15 to be closed.

According to the embodiment of the present disclosure, the gap 15 between the main body 10 of the inner container 1 and the outer case 20 is blocked from the outside air flow, thereby effectively reducing the heat dissipation through the side 21 of the main body 10. In this way, the thermal insulation properties of the inner container 1 can be improved.

Detailed features of the inner container 1 will be described with reference to fig. 6 to 8, in which fig. 6 shows an enlarged view of the portion a in fig. 3, fig. 7 shows an enlarged view of the portion B in fig. 4, and fig. 8 shows an enlarged view of the portion C in fig. 5.

In some embodiments, as shown in fig. 3 and 6, the transition portion 14 may be formed as a groove 141 disposed on the sidewall 12. The flange 26 of the housing 20 can be inserted into the groove 141. In some embodiments, as shown in fig. 3, after the main body 10 is manufactured, the main body 10 can be snapped into the groove 141 of the main body 10 by means of a certain degree of elasticity of the outer shell 20, so as to complete the integral assembly of the liner 1. Such an arrangement can avoid an increase in maintenance costs due to an excessive number of parts.

In another embodiment, as shown in fig. 4 and 7, the transition portion 14 may be formed as a boss 142 disposed on the sidewall 12. The boss 142 may include a table underside 143 and a table topside 144. As shown, the table underside 143 is disposed adjacent the bottom side 18 of the body 10, while the table upper side 144 is parallel to the table underside 143 and is adapted to be coupled to the flap 26 of the housing 20. In this way, the coupling of the body 10 and the housing 20 may be achieved in the form of the boss 142. In some embodiments, as shown in fig. 7, the flap 26 may overlap the upper side 144 of the boss 142, and due to the elasticity of the housing 20, the portion of the side 21 near the top 22 will abut against the boss 142, thereby ensuring that the gap 15 is tightly closed and thus avoiding heat loss.

As shown in fig. 5 and 8, in some embodiments, the transition 14 may be formed as a step 145 provided on the sidewall 12. The step 145 includes a flat portion 146 parallel to the top side 16 of the body 10, and the flap 26 of the housing 20 is adapted to be coupled to the flat portion 146 of the step 145. In some embodiments, flap 26 may be coupled to planar portion 146 of step 145 via a heat resistant glue. In this way, the coupling of the housing 20 to the body 10 is achieved in a cost-effective manner. Since the housing 20 is one-piece, an excessively large number of components can be avoided, whereby heat loss between the components can be effectively controlled.

While some exemplary implementations of the liner 1 according to the present disclosure are illustrated with reference to fig. 3-8, it should be understood that other forms of connection of the body 10 to the housing 20 are contemplated without departing from the concepts of the present disclosure. Such attachment means also fall within the scope of the present disclosure.

In an alternative embodiment, groove 141 may include upper and lower groove walls 147, 148 that are parallel to each other. As shown in fig. 6, the upper groove wall 147 is disposed adjacent to the top side 16 of the body 10, and the flap 26 of the housing 20 is coupled to the upper groove wall 147 and the lower groove wall 148. In addition, in other embodiments, the shape and size of the groove 141 can be matched with those of the flange 26, so that the flange 26 can be firmly inserted into the groove 141, and the sealing effect is further improved.

In other embodiments, as shown in fig. 3, the bottom 28 of the housing 20 may also be provided with an aperture 27, with an edge 29 of the aperture 27 coupled to the bottom side 18 of the body 10. Such arrangement improves the sealability of the connection between the bottom of the case 20 and the bottom of the main body 10, thereby improving the sealability of the gap 15, and thus improving the effect of the inner container 1 against heat loss.

In some embodiments, a temperature sensor (not shown) may be brought into contact with the bottom side 18 of the main body 10 of the liner 1 through the opening 27 to facilitate real-time monitoring of the temperature of the food in the liner 1. In this way, the cooking state of the food can be accurately determined, so that the cooking appliance adjusts the cooking manner accordingly.

As shown in fig. 3, in some embodiments, the body 10 is identified on its side wall 12 with a maximum water level suitable for containing food to be cooked. In an alternative embodiment, the height of the transition 14 above the side wall 12 may not be less than the highest water line of the body 10.

In some embodiments, the gap 15 may be filled with an insulating gas. Such insulating gas may be air. In an alternative embodiment, the gap 15 may be evacuated. Because the vacuum can stop heat transfer and convection, the arrangement is favorable for further improving the heat efficiency of the liner 1.

In an alternative embodiment, the body 10 may be made of a magnetically permeable material. Such a magnetically conductive material may be, for example, iron, SUS430 stainless steel, etc., as long as the selected material may have a magnetic conductive property to ensure a normal operation of the body 10, and the specific material is not limited by the embodiments of the present disclosure.

In an alternative embodiment, the housing 20 may be made of a thermally insulating material. Such an insulating material may for example be plastic. Of course, this is merely exemplary, and in other embodiments, the housing 20 may be made of other materials, such as bakelite, PET material, and the like, as long as the selected material may have certain thermal insulation properties to ensure the thermal insulation function of the housing 20. The specific materials are not limited by the embodiments of the present disclosure.

In a second aspect, embodiments of the present disclosure relate to a cooking appliance that heats by electromagnetic induction. The cooking appliance comprises the inner container 1 described above.

According to the cooking utensil of the embodiment of the disclosure, a good heat preservation effect can be kept in the cooking utensil in a safe, reliable and low-cost mode, and therefore user experience is improved.
