The following describes in detail the embodiments of the present invention. Examples of the embodiments are illustrated in the drawings, and the same or similar reference numerals throughout refer to the same or similar elements, or elements with the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are used only to interpret the present invention, and do not limit the present invention.

The cooking unit 1 of the cooking utensil 40 according to an embodiment of the present invention will now be described with reference to the drawings.

As shown in Figures 1 to 8, the cooking unit 1 of the cooking utensil 40 according to an embodiment of the present invention includes a cooking seat 10 and a first heating device 20.

The cooking seat 10 defines a storage cavity 11 having a top opening 111 for storing a cooking container 41. A user can place the cooking container 41 in the storage cavity 11 through the top opening 111. The user can also move the cooking container 41 out of the storage cavity 11 from the top opening 111 to facilitate cleaning of the cooking container 41. In this way, the user can first place ingredients in the cooking container 41 and then place the cooking container 41 in the storage cavity 11, making operation easier for the user.

The first heating device 20 is configured to be installed on the upper side wall of the storage cavity 11 so that it can be removed from the top opening 111. This allows an operator to attach the first heating device 20 to the side wall of the storage cavity 11 from top to bottom through the top opening 111, making installation of the first heating device 20 easy.

Specifically, whereas the prior art involves winding a heating coil inside the outer shell cover, the first heating device 20 is installed independently as a single unit, and is installed on the upper side wall of the receiving cavity 11 through the top opening 111. This installation method, in which the upper side wall of the receiving cavity 11 is heated by the first heating device 20, is more convenient and quicker, saving installation time and time costs.

The first heating device 20 is used to heat the upper sidewall of the cooking container 41. By heating the upper part of the cooking container 41, the ingredients in the cooking container 41 can be cooked better, heat loss within the cooking container 41 can be reduced, and the ingredients in the cooking container 41 can be better kept warm.

Specifically, when cooking ingredients in a cooking container 41 using the cooking utensil 40 or keeping ingredients in the cooking container 41 warm using the cooking utensil 40, the top of the cooking container 41 is connected to the outside world, so cold air from the external environment can affect the temperature above the cooking container 41, causing the temperature above the cooking container 41 to be lower than the temperature inside the cooking container 41, which in turn can affect the temperature inside the cooking container 41. Therefore, by having the first heating device 20 heat the upper sidewall of the cooking container 41, heat loss within the cooking container 41 can be reduced, thereby better heating the ingredients in the cooking container 41, better cooking the ingredients in the cooking container 41, and achieving a better heat retention effect.

Furthermore, when cold air from the external environment enters above the cooking container 41, the air above the cooking container 41 absorbs the heat inside the cooking container 41, which in turn makes it easier for condensation to form above the cooking container 41. By heating the upper sidewall of the cooking container 41 with the first heating device 20 so that the air above the cooking container 41 can be heated, it is possible to prevent excessive condensation from forming above the cooking container 41 and prevent the condensation from affecting the ingredients inside the cooking container 41.

Therefore, in the cooking unit 1 of the cooking utensil 40 according to the embodiment of the present invention, the first heating device 20 is provided on the upper sidewall of the storage cavity 11 via the top opening 111, allowing for quick installation. The first heating device 20 heats the upper sidewall of the cooking container 41, reducing heat loss within the cooking container 41 and enabling better heating of ingredients in the cooking container 41, resulting in better heat retention.

The cooking unit 1 of the cooking utensil 40 according to a specific embodiment of the present invention will now be described with reference to the drawings.

As shown in Figures 1 to 8, the cooking unit 1 of the cooking utensil 40 according to an embodiment of the present invention includes a cooking seat 10 and a first heating device 20.

In some embodiments of the present invention, the first heating device 20 and cooking seat 10 are removably connected. Specifically, an operator can remove the first heating device 20 from the side wall of the storage cavity 11 through the top opening 111 from bottom to top and move the first heating device 20 out of the storage cavity 11 through the top opening 111. The first heating device 20 can also be attached to the side wall of the storage cavity 11 from top to bottom through the top opening 111, making installation of the first heating device 20 easier and facilitating operations such as replacement and maintenance of the first heating device 20.

In some other embodiments of the present invention, the first heating device 20 and the cooking seat 10 are fixedly connected. That is, the first heating device 20 is attached to the side wall of the receiving cavity 11 from top to bottom through the top opening 111, and then the position of the first heating device 20 is fixed, and the first heating device 20 is then fixed to the cooking seat 10. By allowing the first heating device 20 to stably heat the upper part of the side wall of the cooking container 41, heat loss within the cooking container 41 can be reduced, the food in the cooking container 41 can be better heated, and a better heat retention effect can be achieved.

In some embodiments of the present invention, as shown in FIG. 4, the upper sidewall of the storage cavity 11 is recessed toward the outer peripheral wall of the cooking seat 10, forming a support base 12 on the sidewall of the storage cavity 11, and the first heating device 20 is mounted on the support base 12. The support base 12 is used to limit the position of the first heating device 20, allowing the first heating device 20 to be installed on the sidewall of the storage cavity 11. When a cooking container 41 is installed in the storage cavity 11, the first heating device 20 can heat the upper sidewall of the cooking container 41, reducing heat loss within the cooking container 41 and thereby improving heating of ingredients in the cooking container 41 and making it easier to keep the cooking container 41 warm.

In some embodiments of the present invention, as shown in FIG. 4, the first heating device 20 includes an inner shell cover 21 and a heating element 25, the inner shell cover 21 and the cooking seat 10 are removably connected, and an installation space 211 is formed between the inner shell cover 21 and the upper side wall of the storage cavity 11. The heating element 25 is located in the installation space 211 and is used to heat the upper side wall of the cooking container 41. This reduces heat loss within the cooking container 41, thereby making it easier to better heat the food in the cooking container 41 and keep the cooking container 41 warm.

By placing the inner shell cover 21 between the heating element 25 and the cooking vessel 41, on the one hand, the heating element 25 can be prevented from directly heating the cooking vessel 41, and on the other hand, when the heating element 25 heats the cooking vessel 41, the heating element 25, which is in a high temperature state, can be prevented from coming into direct contact with the cooking vessel 41, which could damage the cooking vessel 41.

In addition, an installation space 211 is defined by the inner shell cover 21 and the sidewall of the storage cavity 11, and the heating element 25 is installed within the installation space 211, providing a relatively stable working space for the heating element 25, preventing objects from the external environment from scratching or damaging the heating element 25, and preventing the high temperatures generated when the heating element 25 is activated from posing a safety risk.

As shown in FIG. 4, in this embodiment, the upper sidewall of the storage cavity 11 is recessed toward the outer peripheral wall of the cooking seat 10, forming an installation space 211. The bottom wall of the installation space 211 is formed as a support base 12 extending horizontally, and the lower part of the first heating device 20 is supported by the support base 12. This allows the first heating device 20 to be installed in an appropriate position on the cooking seat 10, and when a cooking container 41 is installed in the storage cavity 11, the first heating device 20 can heat the upper sidewall of the cooking container 41.

The mounting space 211 has an upper opening and a side opening, the upper opening of which communicates with the top opening 111 of the storage cavity 11, and the inner shell cover 21 removably covers the upper opening and side opening of the mounting space 211. This makes it easy to attach the inner shell cover 21 and heating element 25 to the side wall of the storage cavity 11 through the top opening 111, or to move the inner shell cover 21 and heating element 25 out of the storage cavity 11 through the top opening 111.

The inner shell cover 21 is made of insulating material and separates the heating element 25 from the cooking container 41.

In some alternative embodiments of the present invention, as shown in FIG. 8, the inner shell cover 21 has a first fixing hole 220, the cooking seat 10 has a second fixing hole 13, and the fastening member 31 is inserted into the first fixing hole 220 and the second fixing hole 13 to fasten the inner shell cover 21 and the cooking seat 10 together, thereby fixing the inner shell cover 21 to the cooking seat 10. The heating member 25 is located in the mounting space 211 formed by the inner shell cover 21 and the cooking seat 10, so that when the inner shell cover 21 is fixed to the cooking seat 10, the heating member 25 can be fixed in a specific position and can heat the upper side wall of the cooking container 41.

In some embodiments, as shown in FIG. 8, the first fixing hole 220 is located above the second fixing hole 13, the first fixing hole 220 has an internal thread, the second fixing hole 13 is a through hole, and the fastening member 31 passes through the second fixing hole 13 from bottom to top and then threads into the thread of the first fixing hole 220. The fastening member 31 connects the first fixing hole 220 and the second fixing hole 13 together, thereby connecting the inner shell cover 21 and the cooking seat 10 together.

In some alternative embodiments of the present invention, as shown in FIG. 8, the top of the cooking seat 10 has a fixing portion 14, and the inner shell cover 21 has a fixing post 230 located above the fixing portion 14. The fixing post 230 extends toward the fixing portion 14, allowing the fixing post 230 to be connected to the fixing portion 14 and thus connecting the inner shell cover 21 and the cooking seat 10 together. The heating element 25 is located within the mounting space 211 formed by the inner shell cover 21 and the cooking seat 10, so that the inner shell cover 21 can be fixed onto the cooking seat 10 and the heating element 25 can be fixed within the mounting space 211 at the same time, allowing the heating element 25 to heat the upper sidewall of the cooking container 41.

As shown in Figure 8, in this embodiment, the fixing post 230 extends vertically and is located above the fixing part 14. The fixing post 230 has a first fixing hole 220, which has an internal thread. The fixing part 14 has a second fixing hole 13, which is a through-hole. The fastening member 31 passes through the second fixing hole 13 from bottom to top and then threads into the thread of the first fixing hole 220. The fastening member 31 connects the first fixing hole 220 and the second fixing hole 13 together, thereby connecting the inner shell cover 21 and the cooking seat 10 together.

In some optional embodiments of the present invention, the heating element 25 and the inner shell cover 21 are removably connected, allowing cleaning, maintenance, and other operations to be performed on each of the heating element 25 and the inner shell cover 21.

In some embodiments, when attaching the first heating device 20 to the cooking seat 10, the heating element 25 and the inner shell cover 21 are first assembled together, and then the heating element 25 and the inner shell cover 21 are attached together to the cooking seat 10, allowing the heating element 25 to heat the upper sidewall of the cooking container 41.

Of course, it is also possible to first support the heating element 25 on the support base 12, then install the inner shell cover 21 on one side of the heating element 25 to seal the heating element 25 within the installation space 211, and have the heating element 25 heat the upper side wall of the cooking vessel 41. This type of installation simplifies the structure of the first heating element 20, simplifies the installation procedure, and improves installation efficiency of the first heating element 20.

In some specific embodiments of the present invention, as shown in FIG. 4, the heating element 25 and the inner shell cover 21 are inserted and fitted together, assembling the heating element 25 and the inner shell cover 21 together, thereby fixing the position of the heating element 25 within the mounting space 211. This prevents the heating element 25 from moving within the mounting space 211 when the cooking unit 1 is moved, thereby avoiding any impact on the heating effect of the heating element 25 on the cooking container 41.

Furthermore, by inserting, connecting, and fitting the heating element 25 and inner shell cover 21 together, the relative positions of the heating element 25 and inner shell cover 21 can be quickly determined, thereby enabling the heating element 25 and inner shell cover 21 to be accurately and quickly assembled together, and the heating element 25 and inner shell cover 21 to be smoothly attached to the upper part of the side wall of the storage cavity 11.

In some alternative embodiments of the present invention, as shown in FIG. 4, the heating element 25 includes a mounting bracket 250 and a heating coil 260, with the mounting bracket 250 attached to the outside of the inner shell cover 21 and the heating coil 260 installed on the side of the mounting bracket 250 away from the inner shell cover 21. Because the mounting bracket 250 can separate the heating coil 260 from the inner shell cover 21, when the heating coil 260 heats the cooking vessel 41, the heating coil 260 can avoid direct contact with the inner shell cover 21 or the cooking vessel 41, thereby avoiding damage to the inner shell cover 21 or the cooking vessel 41.

As shown in FIG. 1, in this embodiment, the mounting bracket 250 has a ring-shaped structure, and the heating coil 260 is wound around the mounting bracket 250. The opening of the cooking container 41 has a folded edge 411 extending outward, and the heating coil 260 includes an upper heating portion 261 that is located below and opposite the folded edge 411. This allows the upper heating portion 261 to sufficiently heat the folded edge 411, and ultimately heat the upper sidewall of the cooking container 41.

In some embodiments, the folded edge 411 extending outward at the opening of the cooking container 41 may extend horizontally or at an angle, and the upper heating section 261 may be located below the folded edge 411 and extend horizontally or at an angle. If the folded edge 411 is located within the heating range of the upper heating section 261, heating of the upper heating section 261 relative to the folded edge 411 can be achieved.

Specifically, in the vertical direction, there is at least a range where the projection of the folded edge 411 and the projection of the upper heating section 261 overlap, or the projection of the folded edge 411 can cover the projection of the upper heating section 261, so the upper heating section 261 can sufficiently heat the folded edge 411, and ultimately heat the peripheral area of the opening of the cooking container 41.

In some specific embodiments of the present invention, as shown in FIG. 8 , the mounting bracket 250 has a first position limiting portion 271 and a second position limiting portion 272, which are arranged opposite each other in the vertical direction, and the upper heating portion 261 is located between the first position limiting portion 271 and the second position limiting portion 272. The first position limiting portion 271 and the second position limiting portion 272 can limit the position of the upper heating portion 261 in the vertical direction, thereby allowing the upper heating portion 261 to be located at an appropriate position in the vertical direction of the mounting bracket 250, and allowing the upper heating portion 261 to sufficiently heat the folded edge portion 411 of the cooking container 41.

By wrapping the upper heating section 261 horizontally, the extension direction of the upper heating section 261 matches the extension direction of the folded edge section 411, thereby allowing the upper heating section 261 to sufficiently heat the folded edge section 411, which is advantageous in reducing waste of resources.

As shown in FIG. 8, in this embodiment, the folded edge 411 of the cooking container 41 extends horizontally, the first position limiting portion 271 is located above the second position limiting portion 272, and the first position limiting portion 271 and the second position limiting portion 272 extend horizontally. The upper heating portion 261 is a heating coil that is wound horizontally between the first position limiting portion 271 and the second position limiting portion 272. The first position limiting portion 271 and the second position limiting portion 272 can limit the winding direction of the upper heating portion 261, and the vertical distance H between the upper heating portion 261 and the plane on which the folded edge 411 is located is 5 mm to 15 mm.

When electricity is applied to the upper heating unit 261, it generates a magnetic field within a certain range. By ensuring that the vertical distance H between the plane on which the folded edge 411 of the cooking container 41 is located and the heating coil 260 is within the range of 5 mm to 15 mm, the plane on which the folded edge 411 of the cooking container 41 is located is within the range of the magnetic field generated by the upper heating unit 261, thereby ensuring the heating effect of the upper heating unit 261 on the folded edge 411 of the cooking container 41 and allowing the upper sidewall of the cooking container 41 to be sufficiently heated. This in turn makes it easier to reduce heat loss within the cooking container 41, better heat the food in the cooking container 41, and achieve better heat retention.

In some alternative embodiments of the present invention, as shown in FIG. 8 , the heating coil 260 includes a lower heating section 262, which is positioned opposite the upper sidewall of the cooking vessel 41, thereby allowing the lower heating section 262 to heat the sidewall of the cooking vessel 41 and thereby sufficiently heat the upper sidewall of the cooking vessel 41. As a result, when cooking food in the cooking vessel 41 using the cooking utensil 40, the lower heating section 262 can heat the upper sidewall of the cooking vessel 41, thereby achieving uniform heating of the cooking vessel 41. Furthermore, when food in the cooking vessel 41 needs to be kept warm, the lower heating section 262 can heat the upper sidewall of the cooking vessel 41, thereby reducing heat loss within the cooking vessel 41 and achieving a better heat retention effect.

In some specific embodiments of the present invention, as shown in FIG. 8 , the mounting bracket 250 has a third position limiting portion 273 and a fourth position limiting portion 274 that are arranged opposite each other in the vertical direction, and the lower heating portion 262 is located between the third position limiting portion 273 and the fourth position limiting portion 274. The third position limiting portion 273 and the fourth position limiting portion 274 limit the vertical position of the lower heating portion 262. By wrapping the lower heating portion 262 vertically and aligning the extension direction of the lower heating portion 262 with the extension direction of the side wall of the cooking container 41, the lower heating portion 262 can sufficiently heat the side wall of the cooking container 41.

As shown in Figures 4 and 8, in this embodiment, the heating coil 260 includes an upper heating section 261 and a lower heating section 262, with the upper heating section 261 being located above the lower heating section 262. The mounting bracket 250 has a first support protrusion 281, a second support protrusion 282, and a third support protrusion 283, which are spaced apart in the vertical direction, and which all extend horizontally.

The lower surface of the first support protrusion 281 is formed as the first position limiting portion 271, and the upper surface of the second support protrusion 282 is formed as the second position limiting portion 272. The upper heating portion 261 is wrapped horizontally between the first position limiting portion 271 and the second position limiting portion 272, allowing the upper heating portion 261 to heat the folded edge portion 411.

The lower surface of the second support protrusion 282 is formed as the third position limiting portion 273, and the upper surface of the third support protrusion 283 is formed as the fourth position limiting portion 274. The lower heating portion 262 is wrapped vertically between the third position limiting portion 273 and the fourth position limiting portion 274, allowing the lower heating portion 262 to sufficiently heat the upper part of the side wall of the cooking container 41.

In some specific embodiments of the present invention, as shown in Figures 4 and 8, the upper peripheral wall of the inner shell cover 21 has a cover lid portion 240, which covers the top of the heating coil 260, protecting the heating coil 260 from above and preventing water or objects falling from above from coming into contact with the heating coil 260 and damaging the heating coil 260.

In some embodiments, the upper surface of the cover lid portion 240 extends downward in a direction away from the storage cavity 11, allowing items that fall onto the upper surface of the cover lid portion 240 to fall off the cover lid portion 240 along the upper surface of the cover lid portion 240. This prevents water, foreign objects, etc. from remaining on the cover lid portion 240 for a long period of time, and ensures the cleanliness of the cover lid portion 240.

In some embodiments, as shown in FIG. 4 , the top of the mounting bracket 250 has an insertion connection portion 251, and the cover portion 240 has an insertion hole 241 that is inserted into and fitted with the insertion connection portion 251. The insertion connection portion 251 can be inserted into the insertion hole 241, realizing the insertion connection and fitting between the mounting bracket 250 and the cover portion 240 and securing the mounting bracket 250 and the inner shell cover 21 together. The heating coil 260 is wound around the mounting bracket 250, thereby securing the heating coil 260, mounting bracket 250, and inner shell cover 21 together. This makes it easy to simultaneously attach the heating coil 260, mounting bracket 250, and inner shell cover 21 to the upper side wall of the receiving cavity 11, or to simultaneously remove the heating coil 260, mounting bracket 250, and inner shell cover 21 from within the receiving cavity 11.

A water guide groove 252 is defined between the mounting bracket 250 and the inner shell cover 21, with one end of the water guide groove 252 communicating with the gap between the insertion connection portion 251 and the insertion hole 241 and the other end communicating with the accommodating cavity 11. Water flowing into the cover 240 flows from the gap between the insertion connection portion 251 and the wall of the insertion hole 241 into the water guide groove 252 and then flows along the water guide groove 252 into the accommodating cavity 11, thereby improving the flow guide efficiency of the cover 240.

As shown in FIG. 4 , in this embodiment, the cover 240 is located above the top wall of the mounting bracket 250, and the insertion connector 251 is provided on the top wall of the mounting bracket 250, extending vertically. It should be understood that the above directional limitations are provided solely for ease of illustration and do not impose any restrictions on the actual installation position or orientation of the cooking unit 1 of the cooking utensil 40. The cover 240 is provided with an insertion hole 241, which is formed as a through-hole, and the insertion connector 251 is inserted into and fitted with the insertion hole 241. When water flows over the cover 240, some of the water flows downward from the cooking unit along the cover 240, while some of the water flows along the gap between the insertion connector 251 and the wall of the insertion hole 241 into the water guide groove 252 and then along the water guide groove 252 into the receiving cavity 11.

In some examples, there is a gap between the outside of the mounting bracket 250 and the cooking seat 10, and the gap between the insertion connector 251 and the wall of the insertion hole 241 is located inside the gap. When water flows downward and outward along the cover 240, the water preferentially flows into the gap between the insertion connector 251 and the wall of the insertion hole 241, flows along the gap between the insertion connector 251 and the wall of the insertion hole 241 into the water guide groove 252, and flows along the water guide groove 252 into the accommodating cavity 11. This prevents water from flowing from the gap between the outside of the mounting bracket 250 and the cooking seat 10 to the heating coil 260, thereby preventing damage to the heating coil 260.

Note that the terms "inside" and "outside" referred to here are relative to the center of the storage cavity 11, with the side closer to the center of the storage cavity 11 being the inside and the side farther from the center of the storage cavity 11 being the outside.

In some optional embodiments, as shown in Figures 1 and 4, the inner shell cover 21 has a through hole 212 that connects the water guide groove 252 to the storage cavity 11, allowing water in the water guide groove 252 to flow through the through hole 212 into the storage cavity 11.

As shown in FIG. 1, in this embodiment, the inner shell cover 21 has multiple through holes 212, which are spaced apart along the circumferential direction of the inner shell cover 21. The through holes 212 correspond to the positions of the heating coil 260, and the mounting bracket 250 is installed between the through holes 212 and the coil, allowing heat generated by the heating coil 260 to be transferred directly from the through holes 212 to the cooking vessel 41 via the mounting bracket 250, thereby improving the heating efficiency of the heating coil 260 to the cooking vessel 41.

In some specific embodiments of the present invention, the mounting bracket 250 is a transparent member, and is located between the heating coil 260 and the inner shell cover 21, with the inner shell cover 21 having a cutout or transparent window facing the mounting bracket 250. When the cooking vessel 41 is not installed in the receiving cavity 11, the user can observe the heating coil 260 through the cutout or transparent window of the inner shell cover 21 and the mounting bracket 250, thereby improving user engagement and facilitating visualization of the heating coil 260.

In some embodiments, the heating coil 260 includes a heat-generating element, and when the heating coil heats the upper side of the cooking vessel 41, at least a portion of the heating coil 260 generates heat and emits red light. The emitted red light is irradiated into the storage cavity 11 through the mounting bracket 250 and the cutout or transparent window in the inner shell cover 22, thereby improving the overall aesthetic appearance of the cooking body 1 and informing the user that the heating coil 260 is operating and heating the upper side of the cooking vessel 41.

In some examples, the cutout portion and the through hole 212 are the same.

In some other specific embodiments of the present invention, part of the structure of the inner shell cover 21 is transparent, and the heating coil 260 is located between the mounting bracket 250 and the transparent structure. When the cooking vessel 41 is not installed in the storage cavity 11, the user can observe the heating coil 260 through the transparent structure of the inner shell cover 21, thereby improving user engagement and facilitating visualization of the heating coil 260.

In some embodiments, the heating coil 260 includes a heat-generating element, and when the heating coil 260 heats the upper side of the cooking vessel 41, at least a portion of the heating coil 260 generates heat and emits red light. The emitted red light is irradiated into the storage cavity 11 through the transparent structure of the inner shell cover 22, thereby improving the overall aesthetics of the cooking body 1 and informing the user that the heating coil 260 is operating and heating the upper side of the cooking vessel 41.

In some embodiments of the present invention, as shown in FIG. 3, the cooking body 1 further includes a second heating device 32, which is installed under the cooking seat 10. The second heating device 32 is used to heat at least the bottom of the cooking container 41, and heats the cooking container 41 from the bottom of the cooking container 41 so that the cooking utensil 40 can thoroughly cook the ingredients in the cooking container 41.

In some specific embodiments of the present invention, as shown in Figures 4 and 8, the inner shell cover 21 and the top of the cooking seat 10 have upwardly extending supports 15 that are used to support the cooking container 41, ensuring that the cooking container 41 is positioned vertically and therefore properly within the storage cavity 11.

As shown in Figure 8, in this embodiment, the inner shell cover 21 has an upwardly extending support portion 15 at the top, and the cooking container 41 has a horizontally extending folded edge portion 411 around its periphery. The support portion 15 rests against the underside of the folded edge portion 411 to support the cooking container 41 and position it appropriately within the storage cavity 11.

The cooking utensil 40 according to an embodiment of the present invention will now be described with reference to the drawings.

As shown in Figures 9 and 10, a cooking utensil 40 according to an embodiment of the present invention includes a cooking body 1 according to the above embodiment of the present invention, a cooking container 41, and a lid assembly 42.

The cooking container 41 is detachably installed in the storage cavity 11, and the lid assembly 42 is installed in the cooking body 1. The lid assembly 42 is used to open and close the cooking container 41, so that the lid assembly 42 can seal the cooking container 41 when necessary, allowing the cooking utensil 40 to thoroughly cook the ingredients in the cooking container 41, and the lid assembly 42 can open the cooking container 41 when necessary, allowing the user to easily remove the ingredients in the cooking container 41.

Specifically, when cooking ingredients in the cooking container 41 using the cooking utensil 40 or keeping ingredients in the cooking container 41 warm using the cooking utensil 40, even if the lid assembly 42 closes the opening of the cooking container 41, there is a gap between the two, and cold air from the external environment can reach the periphery of the opening of the cooking container 41 through the gap between the lid assembly 42 and the cooking container 41. The cold air can affect the temperature above the cooking container 41, causing the temperature above the cooking container 41 to become lower than the temperature inside the cooking container 41, and ultimately affecting the temperature inside the cooking container 41. Therefore, by having the first heating device 20 heat the upper side of the cooking container 41, heat loss within the cooking container 41 can be reduced, thereby better heating the ingredients in the cooking container 41, better cooking the ingredients in the cooking container 41, and achieving a better heat retention effect.

In addition, because the temperature of the air in the external environment is lower than the temperature of the air inside the cooking vessel 41, when cold air from the external environment enters above the cooking vessel 41 through the gap between the lid assembly 42 and the cooking vessel 41, the air above the cooking vessel 41 absorbs the heat inside the cooking vessel 41, making it easier for condensation to form above the cooking vessel 41, and the condensation that forms adheres to the lid assembly 42. Heating the upper sidewall of the cooking vessel 41 using the first heating device 20 reduces the formation of condensation and prevents the condensation from affecting the food inside the cooking vessel 41.

The cooking utensil 40 according to this embodiment of the present invention employs the cooking body 1 of the cooking utensil 40 according to the above embodiment of the present invention, and the first heating device 20 is installed on the upper side wall of the storage cavity 11 through the top opening 111, making it easy to quickly install the first heating device 20. The first heating device 20 can heat the upper side wall of the cooking container 41, reducing heat loss within the cooking container 41 and better heating the ingredients in the cooking container 41, thereby keeping the cooking container 41 warm.
