The respective components of the cooking appliance 100 will be described in detail below with reference to fig. 1 to 3.

It should be noted that directional terms used herein in describing the various components of the cooking appliance and their positional relationships, such as "above," "below," "upper side," "lower side," "upward," "downward," "above," "below," "inboard," "outside," "bottom," etc., are relative to the cooking appliance when placed on a horizontal surface and the lid is closed over the pot body.

As shown in fig. 1, the pot body 110 of the cooking appliance 100 may have a generally rounded rectangular parallelepiped shape, a generally cylindrical shape, or any other suitable shape. The pot body 110 has a substantially cylindrical shape or any other suitable shape of the inner pot 130 disposed therein. The inner pot 130 can be freely put into or taken out of the inner pot receiving part of the pot body 110 to facilitate the cleaning of the inner pot 130. The inner pot 130 is used to store food to be cooked, such as rice, soup, etc. The top of the inner pot 130 has a top opening. The user can store food to be cooked in the inner pot 130 through the top opening or take cooked food out of the inner pot 130 through the top opening. The side of the inner pan 130 is at least partially light transmitting. Specifically, in one embodiment of the present invention, the inner pan 130 is made entirely of a light-transmissive material (e.g., glass). In other embodiments of the present invention, a portion of the side of the inner pan 130 may be made of a light-transmitting material.

The pot body 110 is further provided therein with a bottom heating means 140 for heating the inner pot 130. The bottom heating means 140 is disposed under the inner pot 130 to heat the inner pot 130 under or at the bottom of the inner pot 130. The bottom heating means 140 may be an electric hot plate or an induction heating means such as a solenoid coil. Further, the bottom heating device 140 may be an infrared heat generating device. In this case, the bottom of the inner pan 130 also needs to be at least partially transparent to allow the infrared rays radiated from the bottom heating means 140 to enter the cooking space through the bottom of the inner pan 130.

As shown in fig. 1, the shape of the lid 120 of the cooking appliance 100 substantially corresponds to the shape of the pot body 110. For example, the cover 120 may have a rounded rectangular parallelepiped shape. The lid 120 is provided at the pot body 110 in an openable and closable manner for covering the entire top of the pot body 110 or at least the top of the inner pot 130 of the pot body 110. Specifically, in the present embodiment, the lid body 120 may be pivotably disposed above the pot body 110 between the maximum open position and the lid closed position by, for example, a hinge.

As shown in fig. 1, when the cover 120 is closed over the pot body 110, a cooking space is formed between the cover 120 and the pot body 110 (specifically, the inner pot 130 of the pot body 110). The cooking space includes a food storage space and a cavity space. Specifically, the food storage space refers to a space where food is actually stored. The cavity space is positioned above the food storage space. That is, when the cover 120 is covered on the pot body 110, the cavity space is a space between the upper surface of the food and the cover 120.

Preferably, the carbon content of the top infrared heat generating element 151 and the side infrared heat generating elements 152 is greater than or equal to 90%. The term "carbon content" as used herein refers to the mass percentage of carbon element. The top infrared heating element 151 and the side infrared heating element 152 radiate infrared rays to the cooking space. The top infrared heating element 151 and the side infrared heating elements 152 radiate infrared rays of various wavelengths toward the cooking space during cooking. Wherein, the infrared rays radiated from the top infrared heating element 151 and the side infrared heating element 152 have a main wavelength of 1.5 to 25 μm. For example, 1.5. mu.m, 2. mu.m, 5. mu.m, 10. mu.m, 15. mu.m, 20. mu.m, 25 μm, etc. Preferably, the infrared rays radiated from the top infrared heating element 151 and the side infrared heating elements 152 have a dominant wavelength of 5 to 15 μm. It should be noted that the term "main wavelength" as used herein is understood to mean that the infrared rays having a wavelength within this range account for a larger proportion of the infrared rays radiated from the top infrared heat generating element 151 and the side infrared heat generating elements 152, relative to the infrared rays having a wavelength outside this range.

The bottom heating means 140 disposed below the inner pot 130, the top infrared heating element 151 disposed in the cover 120, and the side infrared heating element 152 disposed in the pot body 110 and located at the outer side of the inner pot 130 can heat the inner pot 130 and the cooking space in all directions at the bottom, top, and side, respectively, and thus, the heat utilization efficiency is high.
