Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to a cooking appliance with a floating heating plate. Background Art

[0002] In existing cooking utensils that use heating plates for heating, the heating plates are generally made of aluminum. In order to improve cooking efficiency, most of them will be die-cast with multiple heating tubes and aluminum substrates as a whole, resulting in a relatively bloated overall volume of the heating plate and concentrated heat, which causes the central part of the heating plate to burn and turn yellow due to high temperature, and even causes local deformation of the heating plate, resulting in a larger gap between the part that fits the pot body, making the heat transfer of the corresponding part poor, affecting the uniformity of heating during the cooking process, resulting in a bad taste of the ingredients after cooking, and reducing the user experience. In order to solve this technical problem, existing cooking utensils design the heating plate as a floating heating plate to compensate for the gap problem caused by deformation through the floating of the heating plate.

[0003] However, since most of the existing heating plates are circular heating plates, the heating plate is provided with one or more heating tubes extending in the circumferential direction, and an elastic supporting structure for supporting the heating plate is provided at the bottom of the heating plate. In order to achieve balanced support, the elastic supporting structures are evenly spaced along the circumference of the circular heating plate, so that the elastic supporting structure happens to be opposite to the high-temperature area of ​​the heating plate. Long-term exposure to high temperature can easily cause aging of the elastic supporting structure, affecting its service life, thereby affecting the floating effect of the floating heating plate, and further causing the contact between the heating plate and the bottom of the pot body to be affected, thereby affecting the heat transfer efficiency of the heating plate. Utility Model Content

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a cooking utensil with a floating heating plate comprises a pot body 1 and a heating device, wherein the heating device comprises at least two heating plates 2, wherein at least some of the heating plates 2 are floatably arranged to fit the bottom of the pot body 1, the heating plates 2 are provided with heating tubes 21, wherein the heating tubes 21 comprise a heating section 211 and a cold end section 212 connected to the heating section 211, and a plurality of elastic support members 3 are provided below the floating heating plate 2, wherein at least some of the elastic support members 3 are adjacent to the cold end section 212.

[0041] The cooking utensil of the present application comprises a pot body 1 and a heating device, wherein the heating device comprises a floating heating plate 2 and an elastic support member 3 arranged below the heating plate 2, wherein the elastic support member 3 is used to drive the heating plate 2 to float, and the heating plate 2 is abutted against the bottom of the pot body 1 by the supporting effect of the elastic support member 3, thereby realizing uniform heat transfer from the heating plate 2 to the pot body 1; wherein the heating tube 21 in the heating plate 2 comprises a heating section 211 for supplying heat to the pot body 1 and a cold end section 212 of a temperature control unit of the cooking utensil, the temperature of the heating plate 2 at the cold end section 212 and its surrounding area is lower than the temperature of the heating plate 2 at the heating section 211, and at least part of the elastic support member 3 is set to be in contact with the cold end Segments 212 are adjacent to each other, which can reduce the impact of high temperature on this part of the elastic support member 3, thereby reducing the possibility of deformation and aging of the elastic support member 3 due to long-term exposure to high temperature. On the one hand, it helps to increase the service life of the elastic support member 3 and reduce the frequency of replacement of the elastic support member 3 when the user uses the cooking appliance for a long time; on the other hand, it helps to maintain the stability of the overall structure of at least part of the elastic support member 3, so that the elastic support member 3 can provide more stable support for the heating plate 2, reduce the displacement of the heating plate 2 caused by the deformation of the elastic support member 3, and reduce the possibility of a gap between the heating plate 2 and the bottom of the pot body 1, thereby providing a guarantee for stable and uniform heat transfer from the heating plate 2 to the pot body 1.

[0042] As a preferred implementation of the present application, Figure 2 As shown, the heating tube 21 includes a plurality of first sections 213 arranged adjacent to the outer contour of the heating plate 2 and a second section 214 arranged away from the outer contour of the heating plate 2. A low-temperature zone 22 is formed between the second section 214 and the outer contour of the heating plate 2, and part of the elastic support member 3 is located in the low-temperature zone 22.

[0043] The first section 213 of the heating tube 21 is set to be attached to the outer contour of the heating plate 2, which helps to improve the heating uniformity of the heating plate 2 along the circumferential direction, avoid heat concentration in the middle area of ​​the heating plate 2, thereby reducing the possibility of local heat concentration in the heating plate 2, reducing the temperature difference between the various parts of the heating plate 2, and enabling the heating plate 2 to evenly transfer heat to the bottom of the pot body 1, which helps to improve the uniformity of heat conduction of the cooking appliance; in addition, the second section 214 is set to be arranged away from the outer contour of the heating plate 2, so that a low-temperature zone 22 is formed between the second section 214 and the outer contour of the heating plate 2, which not only provides installation space for part of the elastic support member 3, but also makes a certain distance between the part of the elastic support member 3 installed in the low-temperature zone 22 and the heating tube 21, thereby reducing the heat conduction of the heating tube 21 to the elastic support member 3 installed in the low-temperature zone 22, further improving the service life of the part of the elastic support member 3 and the stability during use, so as to facilitate the stable support of the heating plate 2. In the present application, the first section 213 is set to be attached to the outer contour of the heating plate 2, which means that the first section of the heating tube is extended along the extension direction of the outer contour of the heating plate, and the extension can be parallel to the outer contour of the heating plate, or can be arranged in a zigzag manner along the extension direction of the outer contour of the heating plate, etc. This application does not make specific limitations on this.

[0044] In this embodiment, the forming method of the low temperature zone 22 is related to the outer contour shape of the heating plate 2. In one embodiment, Figure 2 As shown, the heating plate 2 is at a longer distance from the heating tube 21 at its corner, and the second section 214 can be configured to be in the form of an arc transition convex toward the corner of the heating plate 2, so as to form a low-temperature zone 22 between the convex portion of the second section 214 and the corner of the heating plate 2; in another embodiment, if the outer peripheral contour of the heating plate 2 is not sufficient to satisfy a sufficient distance from the heating tube 21 to form the low-temperature zone 22, the second section 214 can be configured to have a concave structure toward the outer peripheral contour of the heating plate 2, so as to increase the distance between the concave portion of the second section 214 and the outer peripheral contour of the heating plate 2, thereby forming a low-temperature zone 22.

[0045] like Figure 2 As shown, the distance between the second section 214 and the outer contour of the heating plate 2 is H1, and the distance between the first section 213 and the outer contour of the heating plate 2 is H2, and H1 is greater than H2, thereby forming a low temperature zone 22 between the second section 214 and the outer contour of the heating plate 2.

[0046] As a preferred embodiment of this implementation, Figure 2 As shown, the heating device includes two heating plates 2 distributed in the left and right directions. With such a configuration, it is convenient to preferably configure the elastic support members 3 installed in two adjacent low-temperature zones 22 to be symmetrically distributed in the left and right directions, which helps to improve the supporting balance of the heating device and avoid the offset of the heating plates 2 caused by the asymmetric installation position of the elastic support members 3, thereby providing a guarantee for the uniformity of the contact between the heating plates 2 and the bottom of the pot body 1, avoiding the phenomenon that a part of the heating plate 2 abuts against the bottom of the pot while there is a gap between other areas of the heating plate 2 and the bottom of the pot body 1, and providing a guarantee for the stable and uniform heat transfer from the heating device to the pot body 1.

[0047] Preferably, the low temperature zones 22 of the two heating plates 2 are arranged adjacent to each other. This arrangement allows the two low temperature zones 22 to be combined, thereby increasing the range of the low temperature zone 22 and further reducing the influence of high temperature on the elastic support member 3.

[0048] This embodiment does not limit the location of the cold end section 212, and it can adopt any of the following examples:

[0049] Example 1: The two heating plates 2 are arranged symmetrically and can float, and the cold end sections 212 of the heating tubes 21 arranged on the two heating plates 2 are arranged back to back.

[0050] Preferably, if Figure 2 , Figure 4 As shown, three elastic support members 3 are respectively provided under each heating plate 2; wherein, one elastic support member 3 is arranged adjacent to the cold end section 212, and the other two elastic support members 3 are respectively located on the inner sides of the two heating plates 2 facing each other, so as to form a triangular support structure for the two heating plates 2. Arranging the three elastic support members 3 into a triangular support structure helps to improve the support stability of the heating plate 2, and the three elastic support members 3 are distributed around the heating plate 2, so that the three support points are spaced a certain distance from each other, avoiding the possibility of stress concentration caused by excessive concentration of support points.

[0051] Example 2: The two heating plates 2 are arranged symmetrically and can float, and the cold end section 212 of each heating tube 21 provided on the two heating plates 2 is located on the inner sides of the two heating plates 2 facing each other.

[0052] Preferably, three elastic support members 3 are respectively provided under each heating plate 2; wherein, one elastic support member 3 is arranged adjacent to the cold end section 212, and the other two elastic support members 3 are respectively located on the sides of the two heating plates 2 facing away from each other, so as to form a triangular support structure for the two heating plates 2. Arranging the three elastic support members 3 into a triangular support structure helps to improve the support stability of the heating plate 2, and the three elastic support members 3 are distributed around the heating plate 2, so that the three support points are spaced a certain distance from each other, thereby avoiding the possibility of stress concentration caused by excessive concentration of support points.

[0053] As a preferred example under this embodiment, the two heating plates 2 are arranged symmetrically on the left and right and can both float, and the two heating plates 2 themselves are symmetrical in the vertical direction. This arrangement makes the left and right heating plates 2 have the same structural form, and when producing the heating plates 2, there is no need to produce the heating plates 2 on the left and the heating plates 2 on the right separately, which reduces the production difficulty of the heating plates 2; in addition, when assembling the heating plates 2, each heating plate 2 can be installed on the left or right side, which saves the assembler the operation of selecting the heating plates 2, thereby improving the assembly efficiency of the heating plates 2.

In one example, the two heating plates 2 are circular, the two heating plates 2 have a common center, and the radius of the heating plate 2 located on the inner side is smaller than the radius of the heating plate 2 located on the outer side. The cooking cavity 11 is set to correspond to the heating plate 2, and the projection of the bottom wall of the cooking cavity 11 toward the heating plate 2 covers the corresponding heating plate 2 respectively. This embodiment does not limit the shape of the heating plate 2, and the heating plate 2 can also be set to be rectangular or other structural forms.

[0061] As a preferred implementation of the present application, Figure 3As shown, the cooking utensil further includes a reflector 4 located below the heating plate 2, and the lower end of the elastic support member 3 abuts against the bottom wall of the reflector 4.
