The utility model provides a cooking utensil, referring to fig. 1 to 6, cooking utensil includes a kind of deep pot body 1 and lid 2, wherein, the internal pot 11 that is equipped with top end open-ended of a kind of deep pot in 1, lid 2 is including being used for in the closing cap pot 11' S top end open-ended bottom cover plate 21 and being used for heating the apron heating device 22 of bottom cover plate 21 to the heating area by the heating region on the bottom cover plate 21 is S1, and the top end open-ended open area of interior pot 11 is S2, satisfies:

the utility model discloses in, through addding the apron heating device 22 that is used for heating end cover plate 21 in lid 2, and set up the ratio between the heating area of the heated region of end cover plate 21 and the open-top area of interior pot 11 into not less than 0.75, so set up the back, combine end cover plate 21's self heat radiation, 0.75's heating area accounts for the ratio and is enough to cover the open-top of interior pot 11 by a large scale, the edible material in the pot carries out the even heat preservation heating of covering type on a large scale in the heat preservation stage, promote the heat preservation effect. During cooking, after the food materials (such as rice, meat, vegetables, liquid and the like) in the inner pot 11 are heated and generate steam, the steam meets the bottom cover plate 21 of the cover body 2, because the temperature of the heated area of the bottom cover plate 21 is raised, and the coverage area of the heated area on the bottom cover plate 21 is larger, the steam is less prone to form condensed water on the bottom surface of the bottom cover plate 21, and the formation of the condensed water on the bottom cover plate 21 of the cover body 2 can be effectively prevented. Therefore, after the user opens the cover, the situation that condensed water is polymerized into water flow and flows downwards along the bottom cover plate 21 is avoided, and the use experience of the user can be improved.

Furthermore, in current cooking utensil, for collecting the operation mesa that a large amount of comdenstion water that flows down from bottom plate 21 sets up the great water-collecting box of volume in order to avoid polluting the user usually in a kind of deep pot body 1, and the utility model discloses in, owing to be difficult for forming the comdenstion water on bottom plate 21's bottom surface, can miniaturize the water-collecting box in the a kind of deep pot body 1, for the remaining design space of complete machine, realize more compact overall structure design, reduce cooking utensil's manufacturing cost, also need not the user frequently to empty the comdenstion water in the water-collecting box in addition, further promote user's use and experience.

The cooking appliance is a cooking appliance capable of cooking food materials, such as an electric cooker or an electric pressure cooker. In addition, the heat generated by the cover plate heating device 22 is transferred to the bottom cover plate 21, and the region for heating the bottom cover plate 21 is the heated region of the bottom cover plate 21.

To avoid the heat waste of the heated area and thus reduce the energy consumption of the cooking appliance, it is preferable that the heating area S1 of the heated area is larger than the opening area S2 of the top end opening, and that:

specifically, the heating area S1 of the heated region and the opening area S2 of the top openingWhen the ratio between the heating area S1 of the heated area and the opening area S2 of the top opening is not less than 1, it means that the heated area on the bottom cover plate 21 should at least completely cover the top opening of the inner pot 11, but if S1 is greater than S2, the non-condensed water generating area on the bottom cover plate 21 is heated unnecessarily, which inevitably results in unnecessary energy waste.

Nowadays, an inner pot heating device for heating the bottom of the inner pot 11 is usually further included in the pot body 1, and the inner pot 11 has a smaller diameter and a deeper depth, so that when the cooking appliance is in the water absorption stage, the food material in the inner pot 11 is heated unevenly due to the fact that the food material in the inner pot 11 does not have rolling convection caused by boiling bubbles, that is, the temperature of the food material relatively close to the pot wall of the inner pot 11 is higher, and the temperature of the food material relatively far away from the pot wall of the inner pot 11 is lower. In view of the above, referring to fig. 4, in the present embodiment, the inner pot 11 is designed to be cylindrical, and the ratio between the maximum diameter of the inner circumferential wall of the inner pot 11 and the maximum depth of the inner pot 11 is set to be not less than 2, so that the food material contained in the inner pot 11 can be heated more uniformly, and particularly, in the water absorption stage, the cooked food can be promoted to have better taste.

Specifically, for the same volume of the inner pot 11, the ratio between the maximum diameter of the inner pot 11 and the maximum depth of the inner pot 11 can be increased to be not less than 2. However, the maximum diameter of the inner pot 11 is increased, so that the heat of the cooked food is easily lost in the heat preservation stage of the cooking appliance, and therefore, by additionally providing the cover plate heating device 22 in the bottom cover plate 21 and setting the ratio of the heating area S1 of the heated area of the bottom cover plate 21 to the opening area S2 of the top opening of the inner pot 11 to be not less than 0.75, a good heat preservation effect can be achieved. In other words, the ratio is set too small, which is not favorable for the effective heat preservation effect of the inner pot with shallow bottom and wide mouth in the heat preservation stage.

In addition, according to the existing cooking volume specification and rated power specification of cooking appliances such as electric cookers, pressure cookers, and the like, the inventors set the preferable range of the heating power of the lid plate heating device 22 to not less than 20W and not more than 30W after trial and error. It will be appreciated that the heating power of the cover plate heating means 22 is preferably within the above-mentioned range, which is easier to obtain and effectively control than the high-powered cover plate heating means 22, in addition to better achieving the purpose of preventing the formation of condensation on the bottom cover plate 21.

Specifically, the cover heating device 22 may have various suitable arrangement types, for example, the cover heating device 22 is an electromagnetic induction heating device or a contact heating device, and the like, without being limited thereto. The bottom cover plate 21 is usually made of conductive metal, and if the cover plate heating device 22 is directly connected with the bottom cover plate 21, the bottom cover plate 21 is also electrified when the cover plate heating device 22 leaks electricity, and a user can be easily electrified or electrically injured by touching the bottom cover plate 21, so that the cover plate heating device 22 is preferably arranged at an interval with the bottom cover plate 21, namely, the cover plate heating device 22 is not in contact with the bottom cover plate 21, the situation that the user is electrified or electrically injured due to the electricity leakage of the cover plate heating device 22 can be effectively prevented, and the safety of the user in use is improved.

When the cover heating device 22 is a contact heating device, referring to fig. 4 to 6, the cover heating device 22 includes a heating seat plate 221 and a contact heating element 222 disposed on top of the heating seat plate 221, and the heating seat plate 221 is disposed above the bottom cover plate 21 at an interval. Wherein, the contact heating element 222 is spaced apart from the bottom cover plate 21 by the heating seat plate 221, and a gap is reserved between the heating seat plate 221 and the bottom cover plate 21, so that the heat generated by the contact heating element 222 is firstly conducted to the heating seat plate 221, and then the heat on the heating seat plate 221 is transferred to the bottom cover plate 21 by heat radiation. With such an arrangement, the heat generated by the contact heating element 222 can be transferred to the heated area of the bottom cover plate 21 through the heating seat plate 221 more uniformly, so as to promote uniform heating of the heated area of the bottom cover plate 21, thereby avoiding an excessive temperature difference between any two points in the heated area (i.e. avoiding a low temperature of a part of the heated area), and being more beneficial to preventing formation of condensed water on the bottom cover plate 21. In addition, when the cover plate heating device 22 is an electromagnetic induction heating device, the electromagnetic induction heating device is disposed above the bottom cover plate 21 at an interval.

Specifically, the contact heating element 222 is disposed on the top of the heating seat plate 221, that is, the contact heating element 222 may be directly mounted on the top surface of the heating seat plate 221, or may be embedded in the top of the heating seat plate 221. For ease of assembly and maintenance, the contact heating element 222 is preferably mounted directly on the top surface of the heating seat plate 221. In addition, the contact heating element 222 may be of various suitable alternative types, for example, the contact heating element 222 is a resistance heating wire, a PTC heating sheet, or an electrothermal film, and the like, but is not limited thereto.

Preferably, the contact heating element 222 is disposed such that the temperature of the heated region should be no less than 60 ℃ and no greater than 80 ℃. It can be understood that the lower the temperature of the heated region is, the more likely the condensed water is formed on the bottom cover plate 21, and accordingly the higher the temperature of the heated region is, the less likely the condensed water is formed on the bottom cover plate 21, but if the temperature of the heated region is higher than a certain value (for example, higher than 80 ℃), not only the amount of condensed water formed on the bottom cover plate 21 cannot be reduced, but also the energy consumption of the contact heating element 222 increases as the temperature of the heated region increases.

Specifically, an inner pot sealing ring 23 is disposed on the outer periphery of the bottom surface of the bottom cover plate 21, the inner pot 11 is disposed with a top edge flanging 111, and when the lid body 2 is in a closed state, the inner pot sealing ring 23 can press against the top edge flanging 111 of the inner pot 11 to form a ring surface seal, i.e., the inner pot 11 is not in direct contact with the bottom cover plate 21, so that when the cover plate heating device 22 is not disposed, the temperature of the outer periphery of the bottom cover plate 21 is lower than the temperature of the central portion of the bottom cover plate 21, so that the rising water vapor is more likely to form condensed water on the outer periphery of the bottom cover plate 21. In order to make the temperature of the heated area of the bottom cover plate 21 more uniform, and thus to be beneficial for preventing the formation of condensed water on the bottom cover plate 21, when the cover plate heating device 22 is a contact heating device, the contact heating elements 222 preferably include at least a first contact heating element and a second contact heating element which are arranged at intervals along the central inward direction, and the heating power of the first contact heating element and the second contact heating element is sequentially reduced; and when the cover plate heating device 22 is an electromagnetic induction heating device, the electromagnetic induction heating device includes a coil base and an electromagnetic induction coil wound on the coil base, and the electromagnetic induction coil preferably includes at least a first electromagnetic induction coil and a second electromagnetic induction coil arranged at an interval in a central inward direction, and heating powers of the first electromagnetic induction coil and the second electromagnetic induction coil are sequentially reduced. The inward direction from the center is a direction from the outer peripheral portion of the lid body 2 toward the center, and when the lid body 2 is circular, the inward direction from the center is a radially inward direction.

Referring to fig. 6, further, after the heating seat plate 221 is additionally provided, the contact heating elements 222 should be distributed as uniformly and widely as possible on the surface of the illustrated circular heating seat plate 221 to uniformly heat the entire heating seat plate 221. Therefore, in the present embodiment, it is further required that the ratio of the area of the heating element distribution region on the surface of the heating seat plate 221 to the surface area of the heating seat plate 221 should be not less than 0.75, so that the heating of the heating seat plate 221 is more uniform, and further, the heat can be uniformly conducted to the bottom cover plate 21.

It should be noted that the heating element distribution region refers to a region on the surface of the heating seat plate 221, where the heating elements 222 are distributed. However, since the heating elements 222 are not regularly distributed, such as uniformly distributed in a closed ring, as shown in fig. 6, the heating element distribution area may be defined as a circular ring area or a circular area centered on the center of the heating base plate 221 in the present embodiment. Taking fig. 6 as an example, the heating element distribution area can be regarded as a circular area concentric with the heating seat plate 221, and the radius of the position where the heating element 222 at the outermost circle is located should be not less than 0.75 of the radius of the heating seat plate 221.

It should be particularly noted that other configurations and functions of the cooking appliance according to the embodiment of the present invention are known to those skilled in the art, and are not described herein in detail to reduce redundancy.
