Description

Cooking equipment with graphene heating function

Technical Field

The utility model relates to the technical field of kitchen electrical equipment, in particular to cooking equipment with a graphene heating function.

Background

With the comprehensive development of technologies related to the field of home appliances, home appliances have been developed in both of the rich and refined aspects. Kitchen electric appliances are one of the household appliances, and are mainly cooking appliances for preserving and processing food materials, and along with the development of enrichment and refinement, specific forms corresponding to various cooking modes such as steaming, baking, frying, air frying and the like are developed in addition to traditional gas cookers, refrigerators, microwave ovens and the like.

Taking an oven as an example, the working principle of the oven is to cook food materials by using circulated hot air flow. Specifically, along with the circulation flow of the hot air flow in the inner container where the food to be cooked is located, when the hot air flow flows through the food, the heat carried in the hot air flow can be transferred to the surface of the food, and parameters such as the flow rate and the temperature of the hot air flow are correspondingly controlled.

In order to heat the hot air flow better, a heating component is added. Such as by placing additional heating coils in the top, bottom, etc. of the oven. Since graphene has excellent thermal and electrical conductivity, a heating structure including graphene has better heating performance than a general heating coil. However, since graphene has a very high hardness, there is a problem in that it cannot be bent when it is processed into a tubular structure.

As an improvement, there is the following processing mode:

as disclosed in chinese patent (CN 212546594U), a heating structure and a steaming oven are disclosed, wherein the heating structure is configured to be disposed in a cavity of the steaming oven, the heating structure includes a lower heating element, the lower heating element is configured to be disposed at a bottom of the cavity, the lower heating element includes a thick film heating plate and a first graphene heating plate, and the first graphene heating plate is disposed around the thick film heating plate. When the first graphene heating plate is electrified to heat, the first graphene heating plate heats food in a heat radiation mode, and the heating efficiency is high.

It can be seen that, in this document, the area of heat radiation is ensured by the extended plate-like structure, the layout mode of the heating plate is not flexible enough and there is a strong correlation between the layout mode and the material of graphene.

As another example, chinese patent (CN 215305077U) discloses a steaming and baking oven, including a water-containing tray body and a box body for enclosing into a cooking cavity, in one embodiment, the position of the water-containing tray body, on which the first insulating layer is printed, is printed with the second insulating layer, the graphene heating wire is packaged between the first insulating layer and the second insulating layer, specifically, the position of the water-containing tray body, on which the first insulating layer is printed, is printed with the second insulating layer, the graphene heating wire is packaged between the first insulating layer and the second insulating layer, the heat generated by electrifying the graphene heating wire can be easily transferred to the water-containing tray body through the second insulating layer, the heat loss is small, and the heating efficiency is high.

It can be seen that in this document, the process of packaging by printing an insulating layer on a graphene heating wire is based on the graphene heating wire, and the insulating layer printed thereon serves as an insulating function and an auxiliary function. Therefore, in this document, the layout manner of graphene is still strongly related to the material of graphene.

Accordingly, there is a need in the art for a new solution to the above-mentioned problems.

With such a configuration, the graphene heating portion can be disposed on the cooking body in a more flexible manner.

Specifically, the material of the carrier portion of graphene, which is a heating effective material, is not necessarily a graphene structure, and thus the shape thereof is not limited by the hardness of graphene. On the premise, the structure can be changed according to actual requirements and can be flexibly arranged at the corresponding position of the cooking main body. For example, the cooking device can be processed into structures such as plate-shaped structures, tubular structures, special-shaped structures and the like according to actual requirements, and is arranged in a local area or all areas of the cooking main body, and specific positions for arrangement are selected.

On the premise of ensuring the functions, the person skilled in the art can select the material of the carrier part and the specific structural form of the carrier part comprising the first carrier according to the actual situation.

The second carrier is illustratively snapped into the interior of the arrangement space formed by the first carrier in an embedded manner, the second carrier only allowing the graphene to be applied in its local area. In this case, it is understood that the arrangement space is further limited by the arrangement of the second carrier, and that the arrangement space can be further planned in detail by the arrangement of the second carrier.

For the cooking device with a graphene heating function, in a possible implementation manner, the graphene coating is coated in the layout space so as to form at least one heating part, wherein in the case that the heating part comprises a plurality of heating parts, at least one part of heating parts are arranged in the layout space in a relatively independent manner.

With this configuration, it is possible to optimize the heating performance of the air in the cooking chamber by differentially controlling the plurality of heating portions.

For the cooking apparatus with a graphene heating function, in one possible implementation manner, the layout space includes an effective layout area related to a manner of radiating heat to the cooking medium, and the graphene coating is coated on the effective layout area.

It will be appreciated that the specific form of the effective layout area may be determined by those skilled in the art based on the actual heat radiation requirements, such as by dividing the effective layout area from within the layout space by way of zonal division or structural distinction.

For the cooking device with the graphene heating function, in one possible implementation manner, the coating track corresponding to the graphene coating is formed on one side of the carrier part, which is close to the effective layout space, and the graphene coating can be coated at any position of the effective layout area.

For the cooking apparatus with the graphene heating function, in a possible implementation manner, the coating track is a protrusion or recess of the carrier portion disposed on a side close to the effective layout space.

With such a constitution, a specific form of the coating trace is given.

Illustratively, the coated track is a groove (recess) provided on the second carrier of the carrier part, such as other grooves including both regular annular, arcuate, linear grooves, and also profiled structures, etc.

Namely: the graphene coating is coated on the first carrier layer and/or the second carrier layer.

For the above cooking apparatus with graphene heating function, in a possible embodiment, the first carrier layer and/or the second carrier layer is/are removably disposed on the cooking body; and/or the first carrier layer and/or the second carrier layer is microcrystalline glass.

If the cooking medium is hot air, the cooking device generally further comprises a fan cover assembly, specifically, the fan cover assembly is formed with a hot air chamber and comprises an air return opening and an air supply opening, and the hot air in the cooking chamber is heated after reaching the hot air chamber through the air return opening and then is reissued to the cooking chamber through the air supply opening. Assuming that the graphene heating part has a certain overlap with the air return and/or air supply function, a through structure should be added, and in particular, the setting position of the through structure should not interfere with the effective layout area so that the hot air flow can reliably circulate between the cooking chamber and the hot air chamber through the through structure. The graphene heating part is part of the fan cover assembly, and at the moment, under the action of the fan, hot air flows between the cooking cavity and the hot air cavity, and through the arrangement of the through structure, the reliability of hot air flow can be ensured.

As shown in fig. 1 to 7, the oven 100 mainly includes a cooking main body 1, a fan housing assembly 2, and a graphene heating part 3, which in this embodiment includes two graphene heating units respectively provided at the top and bottom of the cooking main body. Wherein the cooking body 1 is formed with a cooking chamber (e.g., a liner) for holding food materials to be cooked. If a shelf is arranged in the inner container, the food materials are directly placed in the shelf or placed in a vessel (such as a disk) placed on the shelf. The fan cover assembly 2 is mainly used for forming a circulating hot air flow serving as a cooking medium in the liner, and cooking food materials to be cooked by taking the hot air flow as the cooking medium. The graphene heating part 3 is mainly used for further heating hot air flow in the cooking process.

In one possible embodiment, the fan guard assembly 2 mainly includes a fan guard 21, a fan and a heating coil, and is specifically configured as follows: the inner container is provided with a door body 10 near the user's operation side (e.g., the operation side is the side facing the user and may be generally referred to as the front side), and the body is pivotally provided to the inner container along the front lower edge of the inner container in this embodiment. The inner container is provided with a first backboard 11 and a second backboard 12 in sequence from front to back on one side far away from the user (such as the rear side), a hot air chamber is formed between the front side of the first backboard 11 and a fan cover 21, the fan cover is provided with an air return opening 211 near the middle part of the fan cover, and an air supply opening 212 is arranged around the circumference of the air return opening 211. A fan is arranged at a position corresponding to the return air inlet in the hot air chamber, the fan comprises a motor 221 and a fan 222, the fan is positioned in the hot air chamber (at the front side of the first backboard), the motor is positioned at a position corresponding to the hot air chamber (at the rear side of the first backboard), the motor is fixed on the first backboard through a motor bracket 2211, the motor bracket is simultaneously fixed on the second backboard 12, and the motor is accommodated in an installation space between the first backboard and the second backboard in an assembled state. The motor rotates to drive the fan to rotate at a position facing the air return opening, and the rotation of the fan can lead the air in the inner container into the hot air cavity through the air return opening. A heating coil 23, such as a fan, is disposed in the hot air chamber at a location corresponding to the return air inlet, and in the area encircled by the heating coil. In this way, under the action of the fan, the air in the inner container is sucked into the hot air cavity through the air return opening, and then is heated by the heating coil to be converted into hot air carrying heat, and then the hot air is thrown to the air supply opening at the periphery and is sent into the inner container again. The hot air flow can continuously release the air carrying heat to the surface of the food material to be cooked by circulating in this way, so that the main cooking function is realized.

In this embodiment, the air return opening 211 is a substantially disk-shaped area formed by grid holes, and the air supply opening 212 includes a plurality of air supply points, for example, the plurality of air supply points includes two parts, one part is an annular area surrounding the outer edge of the disk-shaped area, and the other part is a substantially bar-shaped hole structure disposed in other areas on the first back plate. Illustratively, the strip-shaped holes comprise three groups which are arranged on the fan cover from top to bottom, and each group comprises a small group which is symmetrically arranged at the two sides of the air return opening in a left-right separated mode. The number of the air supply points included in each group gradually decreases from top to bottom. Specifically, the upper group includes a symmetrically arranged small group of 8 (4×2) air supply points disposed on both sides of the return air inlet, the middle group includes 4 (2×2), and the lower group includes 2 (1×2).

Obviously, the specific configuration of the air return opening and the air supply opening is only a specific example, and a person skilled in the art can flexibly adjust the configuration according to actual needs, and the air supply opening only includes annular areas surrounding the air return opening and having different radial dimensions, but the annular areas may include one or more of the annular areas, and the annular areas include one area or a plurality of arc-shaped air supply openings (such as 1-2-3 (three adjacent air supply points), a spacing area, 4-5-6 (three adjacent air supply points), a spacing area, and 7-8-9 (three adjacent air supply points)) which are uniformly distributed at intervals.

Wherein, the graphene heating part 3 comprises a carrier part, the carrier part comprises a first carrier fixed on the top wall/bottom wall of the liner, the first carrier comprises a first carrier layer 311 and a second carrier layer 312, a layout space is formed between the first carrier layer and the second carrier layer, and the graphene coating 33 is coated on at least one part of the layout space. Because the first carrier is coated with the graphene coating, the arrangement mode of the graphene coating can be flexibly set according to requirements. In this embodiment, the first carrier layer and the second carrier layer are both glass ceramics (the thermal expansion coefficient of the glass ceramics is basically zero, so that the glass ceramics has good high temperature resistance and can cope with the high temperature environment in the inner container), and the glass ceramics can be fixed at the corresponding position of the inner container in a clamping manner or the like.

In this embodiment, the heating portion (heating coil) and the graphene heating portion in the fan housing assembly have two heating structures, and the graphene heating portion can further heat the hot air flow on the basis of heating the hot air flow by the heating coil, so that the hot air flow obtains higher temperature quality. The graphene heating portion may be disposed at a position corresponding to the fan housing assembly, that is, the graphene heating portion may be disposed at the back of the cooking body. The oven structure can be integrated in this way: the functions of the heating coil pipe and the fan cover in the fan cover assembly are realized through the carrier part at the same time, so that a plurality of through holes serving as a through structure are required to be arranged on a blank area (relative to an area where the graphene coating is arranged) of the carrier part so as to ensure that hot air flows smoothly between the cooking chamber and the hot air chamber. Of course, the heating coils can be arranged on the premise of arranging the graphene heating part, so that the temperature quality of hot air flow is ensured through two heating modes.

The mode of coating the graphene in the layout space can comprise the following two modes:

1) As shown in fig. 2 to 4, in one possible embodiment, the graphene coating is directly applied between the first and second carrier layers. The trend of the graphene in the layout space may be limited to a U-shape (double-line U-shape) as shown in fig. 2, an S-shape (double-line S-shape), a circle shape (circle-like shape) as shown in fig. 3, a square shape (square-like shape) as shown in fig. 4, or the like. Or spraying in a large area in the layout space. Whether spraying with linear trend or large-area spraying is carried out, a plurality of relatively independent heating parts on electric connection can be formed in the layout area, and therefore diversified heating performance of the graphene heating parts can be achieved through differentiated control of the heating parts. Illustratively, each turn in the circular-like structure is defined as a heating portion.

2) As shown in fig. 5, in one possible embodiment, the carrier portion further includes a second carrier 32, for example, a plate-like structure similar to the first carrier or a flexible film-like structure, where the second carrier is used as a film-like structure, for example, a coating track is first formed on the film-like structure, for example, a U-shaped (double-line U-shaped), S-shaped (double-line S-shaped), circular (circular-like), square (square-like) blind groove (concave one) as the coating track may be. On this basis, the following spraying process can be adopted: the graphene coating 33 is coated in the coating track, and then the second carrier containing the graphene coating is pressed between two layers of microcrystalline glass. Or is: firstly, loading a second carrier on one of two layers of microcrystalline glass, then coating a graphene coating 33 in a coating track of the second carrier participating in construction, and finally pressing the second carrier containing the graphene coating and the layer of microcrystalline glass on the other layer of microcrystalline glass.

It can be seen that, in the oven of the present utility model, by the arrangement of the graphene heating portion, the hot air circulating in the inner container can be heated better by means of the good thermal conductivity of graphene, so that the temperature quality of the hot air as a cooking medium is ensured. Under the premise, the specific structural form of the graphene coating can be planned more flexibly according to actual requirements by adopting a structure/process form that the graphene coating is coated on the first/second carrier, so that the problem that the traditional graphene heating pipe cannot process bending can be solved. And a plurality of relatively independent heating parts which are arranged on the electric connection in the arrangement space formed by the carrier parts according to actual requirements, and the temperature quality of the hot air flow is hopefully regulated in a diversified way by carrying out differential control of sectional heating on the heating parts.

Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions will fall within the scope of the present utility model.
