[0043] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings.

[0044] Reference Figure 1 , the present application provides a cooking appliance 10, which includes a lid 11 and a cooking pot body 100. The lid 11 has a shape that substantially corresponds to that of the cooking pot body 100. The lid 11 is pivotally disposed on the cooking pot body 100. The lid 11 can be pivotally connected to the cooking pot body 100 through a pivot shaft, for example, and can freely pivot between a closed position and an open position relative to the cooking pot body 100 about the pivot axis where the pivot shaft is located, so as to facilitate closing and opening of the cooking pot body 100.

[0045] The cooking pot body 100 includes an inner pot 110 and has a cylindrical storage portion. The inner pot 110 can be freely placed into or taken out of the storage portion to facilitate cleaning of the inner pot 110. The inner pot 110 is generally made of a metal material and has a circular opening on its upper surface for containing materials to be heated, such as rice, soup, etc. More specifically, the cooking pot body 100 further includes a base 101, a housing 102, and a middle plate 140. The housing 102 is disposed on the base 101, and the middle plate 140 is disposed on the housing 102. The middle plate 140 is provided with an open mouth allowing the inner pot 110 to enter.

[0046] The cooking pot body 100 includes a heating component 130 for heating the inner pot 110 to heat the inner pot 110. The heating component 130 is arranged below the inner pot 110. The heating component 130 can be a device such as a coil plate. Moreover, the heating component 130 can also have a temperature sensing device, such as a temperature sensing cup 134, which is used to contact the inner pot 110 to sense the temperature of the inner pot 110.

[0047] When the lid 11 is closed on the cooking pot body 100, it covers the inner pot 110 and forms a cooking space between it and the inner pot 110. The lid 11 usually also has a pot mouth sealing ring, which can be made of, for example, rubber material. It is arranged between the lid 11 and the inner pot 110 and is used to seal the cooking space when the lid 11 is in the closed state.

[0048] It can be understood that the cooking appliance 10 according to the present application can be a rice cooker, an electric pressure cooker or other cooking appliances 10, and in addition to the function of cooking rice, the cooking appliance 10 can also have various functions such as cooking porridge.

[0049] It should be noted that the directional terms used in this article to describe the various components and parts of the cooking appliance 10, such as "upper", "lower", "above", "below", "upward", "downward", "upward", "downward", etc. are relative to the cooking appliance 10 in a horizontally placed and upright state. Without other limitations, in the directional terms "inward", "outward", "inwardly", "outwardly", "inner side", "outer side", etc., "inner" means close to the center of the cooking appliance 10, and "outer" means far from the center of the cooking appliance 10.

[0050] Refer to Figures 1 to 4 According to the cooking pot body 100 of the present application, a ceramic heat preservation cover 120 is further included. The ceramic heat preservation cover 120 is arranged between the heating component 130 and the inner pot 110. The inner pot 110 has a side wall 112 and a bottom wall 111. The ceramic heat preservation cover 120 at least partially surrounds the bottom wall 111 and the side wall 112, and the distance L1 between the ceramic heat preservation cover 120 and the bottom wall 111 is less than 3 mm. Preferably, the distance L1 between the ceramic heat preservation cover 120 and the bottom wall 111 is less than 2 mm.

[0051] For the cooking pot body 100 according to the present application, by adopting the ceramic heat preservation cover 120, it has good heat storage capacity, and the distance between the ceramic heat preservation cover 120 and the bottom wall 111 of the inner pot 110 is small, which can effectively absorb the heat lost by the inner pot 110 and return it to the inner pot 110, greatly improving the heat preservation effect.

[0052] Preferably, the distance L2 between the ceramic heat insulation cover 120 and the side wall 112 is less than 3 mm. Further preferably, the distance L2 between the ceramic heat insulation cover 120 and the side wall 112 is less than 2 mm. According to this solution, the distance between the ceramic heat insulation cover 120 and the side wall 112 is also small, further improving the ability to absorb the heat loss of the inner pot 110 and return heat to the inner pot 110. Optionally, a glaze layer is provided on the surface of the ceramic heat insulation cover 120. Thus, the temperature resistance performance of the ceramic heat insulation cover 120 is strengthened. For example, the glazed ceramic heat insulation cover 120 can withstand a temperature of up to 300 °C and can be placed in cold water without cracking when heated to 300 °C.

[0053] More specifically, the ceramic heat insulation cover 120 is disposed on the heating assembly 130. Among them, the heating assembly 130 has a support portion 131, and the support portion 131 can be the main structure of the above-mentioned coil disc. The support portion 131 is provided with a limiting step portion 132, the ceramic heat insulation cover 120 has a lapping step portion 121, the lapping step portion 121 is connected to the limiting step portion 132, and the step flange 133 of the limiting step portion 132 is disposed around the lapping step portion 121. Such a structure is concise and the assembly is simple. Preferably, the height dimension H1 of the step flange 133 is greater than or equal to 2 mm. Due to the poor accuracy of ceramic products, setting the height dimension H1 of the step flange 133 to be larger is beneficial to balance the processing error of the ceramic heat insulation cover 120 and improve the stability of its assembly.

[0054] A limiting portion 141 is provided on the middle plate 140, which is used to limit the up and down movement of the ceramic heat insulation cover 120. In other words, the ceramic heat insulation cover 120 is disposed on the lower side of the middle plate 140 and is limited between the support portion 131 of the heating assembly 130 and the limiting portion 141 of the middle plate 140, thereby making the installation of the ceramic heat insulation cover 120 firm and reliable. More specifically, the ceramic heat insulation cover 120 has an upper opening 122, and the inner pot 110 is placed in the ceramic heat insulation cover 120 through the upper opening 122, and the upper opening 122 of the ceramic heat insulation cover 120 abuts against the lower side of the limiting portion 141.

[0055] As an implementation form, the limiting portion 141 has a limiting rib 142 extending downward, and the limiting rib 142 is disposed along the circumferential direction of the ceramic heat insulation cover 120 inside the upper opening 122. This further improves the limiting effect on the ceramic heat insulation cover 120 and can prevent it from shaking. Preferably, the height dimension H2 of the limiting rib 142 is greater than or equal to 2 mm. Similar to the above, due to the poor accuracy of ceramic products, setting the height dimension H2 of the limiting rib 142 to be larger is beneficial to balance the processing error of the ceramic heat insulation cover 120 and improve the stability of its assembly.

[0056] The bottom of the ceramic heat insulation cover 120 is provided with a bottom opening 123, and the bottom opening 123 forms a bottom opening to allow the temperature sensing cup 134 to pass through. Preferably, the diameter D of the bottom opening is greater than 25 mm. Further preferably, the diameter D of the bottom opening is greater than 30 mm.

The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The features described in one embodiment herein can be applied to another embodiment alone or in combination with other features, unless the feature is not applicable or otherwise stated in that other embodiment.

[0058] The present utility model has been described by the above embodiments, but it should be understood that the above embodiments are only for illustrative and exemplary purposes, and the present utility model is not limited to the above embodiments. More variations and modifications can be made according to the teachings of the present utility model, and these variations and modifications all fall within the scope of protection required by the present utility model.
