Description
Technical Field
[0001] This utility model relates to the field of kitchenware technology, specifically a flexible food warming board. Background Technology
[0002] Whether fried, stir-fried, boiled, steamed, stewed, or braised, maintaining the proper temperature is the primary condition for eating. However, with the fast pace of life and changing lifestyles, people's mealtimes are often inconsistent. Therefore, placing prepared food on a warming board to keep it warm extends its heat retention time, meeting diverse dining needs, reducing waiting time, and avoiding the extra costs associated with reheating food.
[0003] However, current cutting boards on the market only support heating at a single overall temperature, and cannot be divided into independent areas with different temperatures. This makes them unsuitable for the varying heat retention needs of different foods, and the uniform layout results in a mismatch between heat distribution and demand, leading to low energy efficiency.
[0004] Meanwhile, the existing food warmers do not support multiple units in parallel for practical use, and are not suitable for different table sizes or varying numbers of diners. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a flexible warming plate with a universal mold that is compatible with both dual-heating-line partitioned dual-temperature cutting plates and single-heating-line integral single-temperature cutting plates, so as to overcome the shortcomings of the prior art.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a flexible food warming board is provided, including a board body, a heating wire and an end plate. The end plate is provided with a control component. A groove is provided on the back of the board body. The heating wire is embedded in the groove. The groove includes a first groove and a second groove. A wiring groove is provided in the end plate. The wiring groove includes a first connecting groove and a second partitioning groove. The first connecting groove connects the ends of the first groove and the second groove end to end. The second partitioning groove is connected to the first groove and the second groove respectively, so that the first groove and the second groove are not connected.
[0007] The second partition slot has two openings at different locations in the first connecting slot.
[0008] The first connecting groove is an arc-shaped groove.
[0009] The first and second grooves are arranged in an S-shape on the back of the plate in a left-right partition manner. The spacing between the parallel groove lines of the first and / or second grooves is not equal, or the distance between the edge line of the first and / or second groove and the edge of the plate is less than the spacing between two adjacent groove lines.
[0010] The back of the plate is provided with a first protrusion and a second protrusion. The bottom area of the first protrusion is larger than that of the second protrusion, and the lower edges of the first protrusion and the second protrusion are flush.
[0011] The first and second grooves are coated with a colloid, and the heating wire is embedded in the colloid.
[0012] The flexible food warmer comprises several independent food warmer units. A wire connects the output interface of one food warmer unit to the input interface of another, enabling electrical parallel bridging of the units. Each food warmer unit includes a plate body, a heating wire, and an end plate.
[0013] The control components on each food warmer unit control the unit individually.
[0014] The end plate is provided with an input interface and an output interface. The plate body located inside the end plate is provided with a first wire hole and a second wire hole corresponding to the input interface and the output interface. The input interface and the output interface are electrically connected to the control component.
[0015] It also includes an electrical connector, which includes a connector end and a pin. The control component is adapted to the pin to set a switch. The plate body is integrally molded from silicone.
[0016] The above technical solution has the following beneficial effects:
[0017] 1) This utility model has two heating zones, which can be used to heat different zones at different temperatures, making the heat preservation more flexible;
[0018] 2) This utility model can utilize a mold that is compatible with both partitioned dual-temperature cutting boards and integral single-temperature cutting boards;
[0019] 3) The edge of this utility model is narrow and has a large protrusion, which makes the food warming board more stable and less likely to be pushed apart or deformed due to force at a certain point.
[0020] 4) This utility model has a pin switch in the output switch, which is not only aesthetically pleasing, but also provides leakage protection. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] like Figure 1-7As shown, a flexible food warmer includes a board body 1, a heating wire, and an end plate 2. The end plate 2 is provided with a control component. A groove is provided on the back of the board body 1, and the heating wire is embedded in the groove. The groove includes a first groove 31 and a second groove 32. A wiring groove is provided in the end plate 2. The wiring groove includes a first connecting groove 11 and a second partitioning groove 12 and 13. The first connecting groove 11 connects the ends of the first groove 31 and the second groove 32 end to end. The second partitioning grooves 12 and 13 are respectively connected to the first groove 31 and the second groove 32, but the first groove 31 and the second groove 32 are not connected to each other.
[0034] Reference Figure 1 The first groove 31 and the second groove 32 are arranged in an S-shape on the back of the board 1 in a left-right partition manner. The spacing between the parallel groove lines of the first groove 31 and / or the second groove 32 is not equal, or the distance between the edge line of the first groove 31 and / or the second groove 32 and the edge of the board is less than the spacing between two adjacent groove lines, thereby making the edge of the warming board more stable.
[0035] Reference Figure 1 The back of the plate 1 is provided with a first protrusion 21 and a second protrusion 22, wherein the bottom area of the first protrusion 21 is larger than that of the second protrusion 22, and the lower edges of the first protrusion 21 and the second protrusion 22 are flush, so that the plate 1 is not easy to bend or deform when subjected to force at a certain point, thus making its structure more stable.
[0036] The first groove 31 and the second groove 32 are coated with a colloid, and a heating wire is embedded in the colloid.
[0037] Reference Figure 3 The first groove 31 and the second groove 32 are inverted T-shaped grooves, which makes it convenient for the colloid to fully cover the heating wire when applying the colloid, so that it will not be blocked by the protrusions in the groove.
[0038] Reference Figure 8 The flexible food warmer comprises several independent food warmer units. A wire connects the output interface 5 of one food warmer unit to the input interface 4 of another food warmer unit, achieving electrical parallel bridging of the units. Each food warmer unit includes a plate body 1, a heating wire, and an end plate 2.
[0039] The control components on each food warmer unit control the unit individually.
[0040] The end plate 2 is provided with an input interface 4 and an output interface 5. The end plate 2 is provided with a first wire hole and a second wire hole corresponding to the input interface 4 and the output interface 5. The input interface 4 and the output interface 5 are electrically connected to the control component.
[0041] Reference Figure 1It also includes an electrical connector 20 that matches the output interface 5. The electrical connector 20 includes a connecting end and a pin. The output interface 5 is provided with a pin switch adapted to the control component, thereby enabling the output interface 5 to have a leakage protection function. Specifically, when multiple food warmers are used in parallel, the electrical connector 20 is inserted into the output interface 5, and the pin in the electrical connector 20 is inserted into the pin switch in the output interface 5. The pin switch is closed, making the output interface 5 energized. When a food warmer is used alone, the electrical connector 20 is not inserted, and the pin switch in the output interface 5 is open, making the output interface 5 non-energized, thereby achieving the leakage protection function.
[0042] Reference Figure 4-7 The second partition groove has two openings at different positions of the first connecting groove 11, so as to use different wire embedding schemes and produce different products, thereby saving costs. The first connecting groove 11 is an arc-shaped groove, which can save space in the connecting groove.
[0043] Example 1, refer to Figure 4-5 Only one heating wire 61 is embedded in the plate body 1. Part of the first heating wire 61 is embedded in the first groove 31, enters the first connecting groove 11 from the end of the first groove 31 and transitions to the second groove 32. Then the other part is embedded in the second groove 32, thereby realizing the overall single temperature heating function of the warming plate.
[0044] Example 2, refer to Figure 6-7 A first heating wire 61 and a second heating wire 62 are embedded in the plate body 1. The first heating wire 61 is embedded in the first groove 31, then transitions from the end of the first groove 31 to the first connecting groove 11, and then exits through the second partition groove 12. The first heating wire 61 does not enter the second groove 32. The second heating wire 62 is embedded in the second groove 32, then transitions from the end of the second groove 32 to the first connecting groove 11, and then exits through the second partition groove 13. The second heating wire 62 does not enter the first groove 32. Therefore, the first heating wire 61 and the second heating wire 62 can be controlled independently, thereby realizing the partitioned dual-temperature heating function of the food warmer.
[0045] Reference Figure 7 Heating wire limiting groove 14 and heating wire limiting buckle 15 are provided at the transition points from the connecting groove 11 to the first groove 31 and the second groove 32, respectively, to secure the first heating wire 61 and the second heating wire 62. When the first heating wire 61 and the second heating wire 62 transition from the first groove 31 and the second groove 32 to the connecting groove 11, they pass through the heating wire limiting groove 14, and then the heating wire limiting groove 14 and the heating wire limiting buckle 15 form a buckle structure, thereby making it difficult for the first heating wire 61 and the second heating wire 62 to fall off.
[0046] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents. Improvements made without inventive effort should be included within the protection scope of the present invention.
