The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-7, an embodiment of the invention provides a baking tray for being installed in a heat accumulating oven to carry food materials, comprising a baking tray body 1 and a heat accumulating plate 2, wherein the heat accumulating plate 2 is arranged on a food material carrying tray surface 10 of the baking tray body 1.
When the baking tray is used for baking food, the baking tray is arranged in the heat storage oven, the food is placed on the heat storage plate on the food bearing plate surface, the oven is started, the heating element is used for carrying out radiant heating on the food on the heat storage plate, the heat storage plate and the baking tray body can absorb radiant heat, the baking tray body generally has a higher radiation absorption ratio and can absorb a large amount of heat, part of heat absorbed by the baking tray body can be transferred to the heat storage plate, although under the shielding of the food, the radiant heat absorbed by the heat storage plate is less, the heat transferred to the heat storage plate by the baking tray body can make up the defect that the radiant heat absorbed by the heat storage plate is less, on one hand, a large amount of heat can be stored by the heat storage plate, meanwhile, the lower part of the food is heated through thermal conduction, the effect of turning can be achieved, and the influence of temperature fluctuation caused by reheating on the baking effect of the food can be avoided because the baking tray body does not need to be started for turning over operation, and then the baking effect is improved; and through the duty ratio of control heating element, heating element can adopt intermittent type formula work, and when not opening heating element, heat is penetrated to the food inside by food upper surface, and food lower part heat is conducted to food by the heat accumulation board, then upwards permeates in the food inside, can prevent to keep on heating element, the condition of inside not cooked outside scorching appears.
It should be noted that, the specific mode that the heat storage plate 2 is arranged on the baking tray body 1 may be that an installation groove matched with the size and the number of the heat storage plates 2 is arranged on the food material carrying tray surface on the baking tray body, wherein the number of the heat storage plates 2 may be one or multiple, and may be selected and arranged according to actual requirements. And generally in order to guarantee the planarization of the food material loading tray surface of the baking tray body, after the heat storage plate 2 is mounted to the mounting groove, the top surface of the heat storage plate 2 is generally flush with the food material loading tray surface.
It should be noted that, the oven body 1 is generally configured as a rectangular shape, and may be configured as other shapes according to actual needs, which is not limited in detail herein.
In addition, as will be appreciated by those skilled in the art, the tray body used in the oven generally has a high thermal conductivity and a low heat capacity, and the heat absorbed by the tray body can be transferred to the heat storage plate more quickly by means of thermal conduction. The baking tray structure provided by the invention is particularly suitable for ovens mainly heated by radiation, and has more obvious effect.
In order to better understand the technical effects of the baking tray provided by the invention, the following is exemplified in combination with specific application scenarios:
scene one: for baking thin food materials with uniform thickness and double sides, such as chicken wings, steak, toast, potato chips and the like, food is placed on a heat accumulation plate of a baking tray, a heating element (a heating pipe can be particularly adopted), part of the radiation of the heating element irradiates the upper surface of the food, the other part irradiates the upper surface of a baking tray body which is not covered by the food, the baking tray body has high radiation absorptivity, and after the heat is absorbed, the heat is transferred to the heat accumulation plate to heat the lower surface of the food. (for the traditional oven for baking steaks, the water needs to be decocted and locked on the frying pan on both sides before the steaks are put into the oven, but the baking tray provided by the invention is used for baking, so that the steaks can be baked without being decocted, the same baking effect can be achieved, and the baking time can be reduced, and the efficiency can be improved).
Scene II: for foods with thicker baked food materials, such as whole chickens, sheep legs and the like, the foods are placed on a heat accumulation plate of a baking tray, a heating element is started, and part of heat is transferred to the upper surface of the foods, so that the food has the advantages of quickly locking moisture, enabling the meat inside to be tender and achieving the baking effect of being crisp outside and tender inside; the other part of heat is absorbed by the baking tray body and is transferred to the heat accumulating plate, so that the heat accumulating plate can store a large amount of heat and heat the lower part of food through heat conduction; at the moment, the duty ratio of the heating element is controlled, the heating element works intermittently, when the heating element is not started, heat permeates from the upper surface of the food to the interior of the food, heat at the lower part of the food is conducted to the food by the heat storage plate and then permeates upwards in the interior of the food, and the condition that the heating element is continuously started and the interior is not cooked and the exterior is burnt can be prevented.
Scene III: for food materials with higher heat at the bottom, such as baked egg tarts, pizzas and the like, the heating element is started, the baking tray body and the heat accumulating plate are directly irradiated, heat is stored in the heat accumulating plate, then food is placed on the heat accumulating plate, the food is baked by the heat accumulating plate, if the temperature required by the food is lower, the food can be met only by the heat accumulating plate, if the temperature required by the food is higher, the heating element can be started for auxiliary heating, the heating element runs at low power, and meanwhile, the temperature disturbance in the oven cavity is uniform by means of back hot air.
In some specific embodiments, the baking tray may further include a phase-change heat exchanger 3 disposed between the baking tray body 1 and the heat storage plate 2, where the phase-change heat exchanger 3 is used to transfer heat of the baking tray body 1 to the heat storage plate 2; the phase change heat exchanger 3 is loaded with a phase change medium, and the phase change heat exchanger 3 comprises an evaporation end and a condensation end which is higher than the evaporation end, wherein the evaporation end is embedded in the baking tray body 1, and the condensation end is embedded in the heat storage plate 2. Through setting up phase change heat exchanger 3, the heat of overware body 1 absorptive heat can be faster transfer to the heat accumulation board, helps realizing the upper and lower surface simultaneous heating of edible material.
The basic working principle of a phase change heat exchanger should be understood by those skilled in the art: the liquid working medium in the phase-change heat exchanger absorbs the latent heat at the evaporation end to be changed into gas, the steam flows to the condensation end to release heat to be condensed into liquid under the tiny pressure difference, and the liquid flows back to the evaporation section along the porous material under the action of capillary force and gravity. And the heat is continuously transferred from one end of the phase change heat exchanger to the other end by the circulation.
In a further embodiment, the phase-change heat exchanger 3 may be in a specific structural form of a heat pipe, and the heat pipe specifically includes an evaporation pipe section 31 for forming an evaporation end and a condensation pipe section 32 for forming a condensation end, where the evaporation pipe section 31 is embedded in the baking tray body 1, and the condensation pipe section 32 is embedded in the heat storage plate 2; the heat pipes are multiple in number and are uniformly distributed along the periphery of the heat storage plate 2. By designing the heat pipe into the structure form, the heat transfer speed of the phase-change heat exchanger is faster, and of course, it can be understood that in the practical application process, the phase-change heat exchanger structure with other structure forms, such as a blowing-up plate type phase-change heat exchanger, can be adopted, and the heat transfer speed is not limited in detail. It should be noted that the size and number of the heat pipes may be set according to actual requirements, such as an area ratio of the heat accumulation plate to the baking tray body, which is not limited in detail herein.
In a further embodiment, the upper surface of the heat storage plate 2 near the edge may be further provided with slots corresponding to the condenser tube sections 32 one by one, and the condenser tube sections 32 are embedded in the slots. It should be understood, of course, that the above manner of slot-embedding is merely an example of the mounting manner of the condensation pipe section 32 to the heat storage plate 2 according to the embodiment of the present invention, and other arrangements, such as a plug-in structure, may be adopted in the practical application process, which is not limited in this regard.
In addition, the baking tray body 1 can be provided with corresponding jacks, and the evaporation tube section 31 can be inserted into the jacks of the baking tray body 1 to realize heat transfer.
In still further embodiments, the highest point of the top surface of the condensation pipe section may be designed to be disposed close to the upper surface of the heat accumulation plate 2, or may be designed to be disposed flush with the upper surface of the heat accumulation plate 2. Through this kind of arrangement mode, when placing food on the heat accumulation board, food can be more close to or direct contact heat transfer with the condensation pipeline section, and heat transfer efficiency is higher.
In some more specific embodiments, the thermal storage plate 2 may be specifically formed by firing cordierite at a high temperature, for example, at a temperature of 1200 ℃ or higher, so as to achieve no residue of harmful components. It will be understood, of course, that the thermal storage plate 2 formed by firing cordierite at high temperature is merely a preferred example of the embodiment of the present invention, and other thermal storage plates of other materials known to those skilled in the art, such as stone or ceramic with good thermal storage performance, may be used in the practical application, which is not limited in any way.
In some specific embodiments, the top surface of the thermal storage plate 2 may also be formed with a plurality of minute pores that are uniformly arranged. By designing the tiny pores, moisture exuded from the food (such as dough) can be absorbed, and heat can be uniformly distributed over the whole food.
In some more specific embodiments, the bakeware body 1 may specifically include a main body 11 and a side wall 12 formed on a circumferential edge of the main body 11, where a flange structure 13 extending away from the main body 11 is formed on the side wall 12, and the flange structure 13 is used to cooperate with two side wall clamping grooves 40 of the heat storage oven to implement the installation of the bakeware. By designing the baking tray body 1 into the structure form, the baking tray is more convenient to install to the heat accumulating oven.
The invention further provides a heat accumulating oven, which comprises an oven body 4, wherein a heating element 41 and a baking tray are arranged in the oven body 4, and the baking tray is the baking tray described in any scheme.

Specifically, the heating element 41 may take a structure of a heating pipe, and the graphene conductive heating coating 41a is formed on an inner wall surface of the heating pipe, and is plated in an insulating pipe in a coating form due to extremely high conductivity, and is assembled in an oven in a structure of the heating pipe. The insulating tube can be made of quartz tube with high infrared transmittance, has the advantages of high softening temperature, low thermal expansion coefficient, high mechanical strength, good chemical stability and the like, and is suitable for high-temperature working environment in an oven.
