Description

TECHNICAL FIELD

[0001] The utility model relates to life electric appliance technical field, specifically, relate to a kind of cooking equipment. BACKGROUND

[0002] At present, the heating mode of electric rice cooker mostly adopts electric heating disc heating, i.e. the heat source is hot disc, which heats the metal inner pot by heat conduction, and then heats the food materials. However, the electric heating disc uses heat pipe to generate heat, which belongs to linear heat source, and has the problem of uneven heat transfer caused by concentrated heating.

[0003] To improve the above problems, the related technology uses a film heating electric heating disc. The electric heating disc uses a graphene heating film covered on a glass substrate to achieve rapid heating and uniform heating. However, due to the stamping forming of the metal inner pot, there is a flatness error at the bottom, or foreign matter such as rice grains is stuck to the bottom of the pot during use, which causes poor contact between the glass substrate and the metal inner pot. The heat generated by the heating film cannot be quickly transferred to the metal inner pot to heat the food materials. The heat will form heat accumulation on the glass substrate, causing abnormal film temperature of the heating film and affecting the service life of the heating film. SUMMARY

[0004] Embodiments of the present utility model aim to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, the first aspect of the embodiments of the present utility model provides a cooking equipment.

[0006] Therefore, the first aspect of the embodiments of the present utility model provides a cooking equipment.

[0007] The cooking equipment provided by the embodiments of the present utility model includes a pot body, a heating member and a heat transfer member. Specifically, the heating member is arranged on the outer side of the pot body for heating the pot body. Optionally, the pot body is provided with a cooking cavity for accommodating food materials. The graphene heating part generates heat when powered on, which is transferred to the pot body and then to the food materials in the cooking cavity through the pot body to heat and cook the food materials in the cooking cavity.

[0008] It can be understood that the resistance characteristic of the graphene heating paste presents a negative temperature coefficient, that is, the resistance decreases as the temperature increases, and the heating power and the power density increase. When the contact between the pot body and the substrate is poor, that is, there is an air layer between the pot body and the substrate, the heat generated by the part of the graphene heating part opposite to the air layer cannot be quickly transferred to the pot body, causing the heat generated by the graphene heating part to be accumulated on the substrate, and the temperature rises rapidly. At the same time, due to the rapid temperature rise, the resistance of the part of the graphene heating part decreases rapidly, and the rapid decrease of the resistance further causes the increase of the power density, and under the condition of such a cycle, the local temperature of the graphene heating part is easy to exceed the use temperature, and the graphene heating part is damaged.

[0009] Since the heat transfer member is arranged between the outer wall of the pot body and the substrate to fill the air layer that may be formed between the pot body and the substrate, the heat generated by the graphene heating part and transferred to the substrate is absorbed by the heat transfer member and quickly transferred to the pot body via the heat transfer member, thereby improving the heat transfer efficiency, effectively avoiding the risk of the heat generated by the graphene heating part being accumulated on the substrate to cause the local temperature of the graphene heating part to exceed the use temperature, prolonging the service life of the graphene heating part, improving the uniformity of the heating of the food in the pot body, and further improving the cooking effect.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0058] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0059] The following reference Figures 1 to 5 To describe a cooking apparatus 100 provided according to some embodiments of the present invention.

[0060] In one embodiment according to this application, such as Figure 1 and Figure 5As shown, a cooking device 100 is provided, the cooking device 100 comprises a pot body 110, a heating piece 120 arranged outside the pot body 110 and used for heating the pot body 110, the heating piece 120 comprises a substrate 121 and a graphene heating part 122 arranged on a side of the substrate 121 away from the pot body 110, and a heat transfer piece 130 arranged between the outer wall of the pot body 110 and the substrate 121.

[0061] The cooking device 100 provided by the embodiment of the utility model comprises the pot body 110, the heating piece 120 and the heat transfer piece 130, specifically, the heating piece 120 is arranged outside the pot body 110 and used for heating the pot body 110, optionally, the pot body 110 is provided with a cooking cavity, the cooking cavity is used for containing food materials, the graphene heating part 122 generates heat under the condition of being electrified, the heat is transferred to the pot body 110 and is transferred to the food materials in the cooking cavity through the pot body 110, so as to heat and cook the food materials in the cooking cavity.

[0062] It can be understood that the resistance characteristic of the graphene heating paste presents a negative temperature coefficient, that is, the resistance decreases with the increase of temperature, and the heating power and the power density are increased. When the contact between the pot body 110 and the substrate 121 is poor, that is, there is an air layer between the pot body 110 and the substrate 121, the heat generated by the part of the graphene heating part 122 opposite to the air layer cannot be quickly transferred to the pot body 110, so that the heat generated by the graphene heating part 122 is gathered on the substrate 121, and the temperature is quickly increased. At the same time, due to the rapid increase of temperature, the resistance of the part of the graphene heating part 122 is quickly decreased, and the rapid decrease of resistance further leads to the increase of power density, so under the condition of such circulation, the local temperature of the graphene heating part 122 is easy to exceed the use temperature, and then the graphene heating part 122 is damaged.

[0063] Since the heat transfer piece 130 is arranged between the outer wall of the pot body 110 and the substrate 121 to fill the air layer possibly formed between the pot body 110 and the substrate 121, the heat generated by the graphene heating part 122 and transferred to the substrate 121 can be absorbed by the heat transfer piece 130 and quickly transferred to the pot body 110 through the heat transfer piece 130, so that the heat transfer efficiency is improved, and the risk that the heat generated by the graphene heating part 122 is gathered on the substrate 121 to cause the local temperature of the graphene heating part 122 to exceed the use temperature is effectively avoided, which is beneficial to prolong the service life of the graphene heating part 122 and improve the uniformity of the heating of the food materials in the pot body 110, and then the cooking effect is improved.

[0064] In some embodiments, optionally, one side of the heat transfer piece 130 facing the pot body 110 is attached to the outer wall of the pot body 110, and / or the other side of the heat transfer piece 130 away from the pot body 110 is attached to the substrate 121.

[0065] In this embodiment, specifically, one side of the heat transfer piece 130 that faces the pot body 110 is attached to the outer wall of the pot body 110, that is, the upper surface of the heat transfer piece 130 is attached to the outer wall of the pot body 110. Alternatively, the side of the heat transfer piece 130 that faces away from the pot body 110 is attached to the base plate 121, that is, the lower surface of the heat transfer piece 130 is attached to the base plate 121. Alternatively, the upper surface of the heat transfer piece 130 is attached to the outer wall of the pot body 110, and the lower surface of the heat transfer piece 130 is attached to the base plate 121.

[0066] By attaching the upper surface of the heat transfer piece 130 to the outer wall of the pot body 110 and / or attaching the lower surface of the heat transfer piece 130 to the base plate 121, the heat transfer efficiency is further improved, heat generated by the graphene heating part 122 is prevented from being concentrated on the base plate 121, the graphene heating part 122 is prevented from exceeding the use temperature and being damaged during the operation of the cooking device 100, the reliability of the cooking device 100 is improved, and the effective operation of the cooking process is ensured.

[0067] As shown in FIG. 1, Figure 4 In some embodiments, the graphene heating part 122 includes a plurality of heating segments 123, and the plurality of heating segments 123 are arranged at intervals and attached to the heat transfer piece 130 and the base plate 121 opposite at least one heating segment 123 in the thickness direction of the base plate 121.

[0068] In this embodiment, the graphene heating part 122 includes a plurality of heating segments 123, and specifically, the plurality of heating segments 123 are arranged at intervals. Since the heat transfer piece 130 and the graphene heating part 122 are respectively located on both sides of the base plate 121 in the thickness direction, and the plurality of heating segments 123 respectively generate heat when the graphene heating part 122 is powered.

[0069] By attaching the heat transfer piece 130 opposite at least one heating segment 123 to the base plate 121, it is ensured that the heat generated by the heating segment 123 is absorbed by the heat transfer piece 130 as much as possible via the base plate 121, and then transmitted to the pot body 110 via the heat transfer piece 130, thereby improving the heat transfer efficiency, ensuring the heat generated by the heating segment 123 to be exported, preventing the heat generated by a single heating segment 123 from being locally concentrated on the base plate 121, improving the reliability of the heating element 120, and prolonging the service life of the heating element 120.

[0071] In this embodiment, specifically, the heat transfer piece 130 includes a metal piece 131, or the heat transfer piece 130 includes a heat-conducting silica gel piece. The specific configuration can be set according to actual needs.

[0072] In detail, the heat transfer piece 130 includes a metal piece 131. It can be understood that the metal material has good heat conduction performance and is a high-quality heat transfer medium. By arranging the metal piece 131 between the outer wall of the pot body 110 and the base plate 121, the heat generated by the graphene heating part 122 and transferred to the base plate 121 can be absorbed by the metal piece 131 and quickly transferred to the pot body 110 through the metal piece 131, which improves the heat transfer efficiency and effectively avoids the risk that the heat generated by the graphene heating part 122 exceeds the use temperature due to heat accumulation on the base plate 121, thereby prolonging the service life of the graphene heating part 122. In addition, since the metal piece 131 is arranged on the side of the base plate 121 facing the pot body 110, it can play a role in preventing wear and tear during repeated taking and placing of the pot body 110, and also has the effect of beautifying the appearance.

[0073] The heat transfer piece 130 includes a heat-conductive silica gel piece. It can be understood that the heat-conductive silica gel piece has good heat transfer effect and is generally a flexible piece that can effectively fill the gap between the outer wall of the pot body 110 and the base plate 121, reduce the air layer formed between the outer wall of the pot body 110 and the base plate 121, and achieve good contact between the heat transfer piece 130 and the outer wall of the pot body 110 and between the heat transfer piece 130 and the base plate 121, which is conducive to further improving the heat transfer efficiency and avoiding heat accumulation of the graphene heating part 122 on the base plate 121, thereby prolonging the service life of the graphene heating part 122.

[0075] In this embodiment, it can be understood that the metal piece 131 is generally a rigid material. By arranging the heat-conductive layer 140 between the metal piece 131 and the base plate 121, the gap between the metal piece 131 and the base plate 121 can be effectively filled to ensure sufficient contact between the metal piece 131 and the base plate 121, thereby preventing the metal piece 131 from being deformed due to high temperature and causing poor contact between the metal piece 131 and the base plate 121. The heat generated by the graphene heating part 122 is quickly transferred to the pot body 110 through the base plate 121, the heat-conductive layer 140, and the metal piece 131 in turn, and then transferred to the food materials in the pot body 110 through the pot body 110, which is conducive to further improving the heat transfer efficiency and avoiding heat accumulation of the graphene heating part 122 on the base plate 121.

[0076] As shown in FIG. 1, Figure 2As shown, in some embodiments, the metal piece 131 is provided with at least one groove 132 on the side away from the pot body 110, and a portion of the heat conduction layer 140 is located in the at least one groove 132 and in contact with the groove wall of the groove 132.

[0077] In this embodiment, it is defined that the metal piece 131 is provided with at least one groove 132 on the side away from the pot body 110, and specifically, a portion of the heat conduction layer 140 is located in the at least one groove 132, and the portion of the heat conduction layer 140 located in the groove 132 is in contact with the groove wall of the groove 132. On the one hand, it can effectively avoid the situation that the metal piece 131 is deformed at high temperature and causes poor contact with the base plate 121, realize effective filling of the gap between the metal piece 131 and the base plate 121, improve the heat conduction efficiency of the graphene heating part 122, and avoid heat accumulation. On the other hand, it can also increase the contact area between the heat conduction layer 140 and the metal piece 131, which is conducive to further improving the heat conduction efficiency.

[0078] Optionally, the number of grooves 132 is multiple, and the multiple grooves 132 are arranged at intervals.

[0079] In some embodiments, optionally, the heat conduction layer 140 includes a heat conduction silicone grease layer.

[0083] In some embodiments, optionally, based on that the heat conduction piece 130 includes a heat conduction silicone rubber piece, the heat conduction silicone rubber piece is a flexible piece.

[0084] In the embodiment, since the heat-conducting silica gel member is a flexible member, the gap between the outer wall of the pot body 110 and the base plate 121 can be effectively filled, the air layer formed between the outer wall of the pot body 110 and the base plate 121 is reduced, the good contact between the heat transfer member 130 and the outer wall of the pot body 110 and between the heat transfer member 130 and the base plate 121 is achieved, the heat transfer efficiency is further improved, the heat aggregation of the heat generated by the graphene heating part 122 on the base plate 121 is avoided, and the service life of the graphene heating part 122 is prolonged.

[0085] As shown in Figure 1 and Figure 2 In some embodiments, optionally, the side of the heat transfer member 130 away from the pot body 110 is provided with a mounting groove 133, and at least a part of the base plate 121 is embedded in the mounting groove 133.

[0086] In the embodiment, since at least a part of the base plate 121 is embedded in the mounting groove 133, the thickness of the heating member 120 and the heat transfer member 130 as a whole is reduced, the lightness and thinness are achieved, and the occupied space of the heating member 120 and the heat transfer member 130 as a whole in the height direction of the cooking device 100 is also reduced. At the same time, embedding at least a part of the base plate 121 in the mounting groove 133 also helps to improve the assembly effect between the base plate 121 and the heat transfer member 130, ensures that the heat generated by the graphene heating part 122 can be effectively absorbed by the heat transfer member 130 via the base plate 121, avoids heat aggregation, and helps to prolong the service life of the graphene heating part 122.

[0087] Optionally, the heat transfer member 130 and the base plate 121 are connected by screws or buckles.

[0088] As shown in Figure 2 In some embodiments, optionally, the heat transfer member 130 comprises a heat transfer body 134 and a mounting part 135, wherein the heat transfer body 134 is arranged between the outer wall of the pot body 110 and the base plate 121, the mounting part 135 is connected to the side of the heat transfer body 134 away from the pot body 110 and encloses the heat transfer body 134 to form the mounting groove 133; wherein the thickness of the heat transfer body 134 is greater than 0.5 mm and less than 20 mm.

[0089] In this embodiment, the heat transfer member 130 is defined to include the heat transfer body 134 and the mounting portion 135, specifically, the mounting portion 135 is arranged at the side of the heat transfer body 134 away from the pot body 110, and the mounting portion 135 and the heat transfer body 134 enclose the mounting groove 133, since at least part of the substrate 121 is embedded in the mounting groove 133, it is beneficial to reduce the thickness of the heating member 120 and the heat transfer member 130 as a whole, to realize thinning, and to reduce the occupied space of the heating member 120 and the heat transfer member 130 as a whole in the height direction of the cooking device 100. At the same time, embedding at least part of the substrate 121 in the mounting groove 133 is also beneficial to improve the assembly effect between the substrate 121 and the heat transfer member 130, to ensure that the heat generated by the graphene heating part 122 can be effectively absorbed by the heat transfer member 130 via the substrate 121, and to avoid heat accumulation.

[0090] The thickness of the heat transfer body 134 is between 0.5mm and 20mm, which realizes effective heat conduction performance, prevents heat generated by the graphene heating part 122 from accumulating on the substrate 121, avoids the heat transfer body 134 being too thick to make the overall thickness of the heating member 120 and the heat transfer member 130 too thick, and further causes the heat transfer member 130 and the heating member 120 as a whole to occupy a larger space in the cooking device 100, while improving the heat transfer efficiency, it is beneficial to reduce the volume of the cooking device 100.

It can be understood that the first electrode 124 and the second electrode 125 are respectively connected to the power supply, so that the graphene heating part 122 can generate heat under the condition that the first electrode 124 and the second electrode 125 are powered on, to realize the heating function of the heating member 120.
