Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and particularly to a food warming plate. Background Art

[0002] A food warming plate is a kitchen appliance used for keeping food warm. The heated food warming plate can heat and keep warm the food placed thereon.

[0003] Silicone food warming plates mainly use silicone as the panel, and a plastic shell is arranged on the side of the silicone panel. A circuit board is fixed in the plastic shell, and a sealed cavity structure is formed between the plastic shell and the silicone panel. Such silicone food warming plates use NTC as the temperature measuring element. In related technologies, a cavity can be arranged in the silicone panel, and the NTC is placed in this cavity to sense the temperature of the silicone panel. However, since the NTC senses temperature with a certain lag, the temperature fluctuation of the food warming plate will be relatively large. Or, the heating wire can be extended into the plastic shell, and the NTC is also arranged in the plastic shell, and the NTC is pressed on the heating wire. The NTC senses the temperature of the heating wire. Although this method improves the temperature sensing performance of the NTC, since the heating wire generates heat, the temperature inside the plastic shell will increase. When the temperature difference between the inside and outside of the plastic shell is large, condensed water will be formed inside the plastic shell, which will affect the normal operation of the circuit board. Summary of the Utility Model

[0004] Based on this, this application provides a food warming plate, in which the temperature measuring accuracy of the temperature measuring component is relatively high, and the heating element will not affect the normal operation of the control main board.

[0005] The food warming plate provided by the embodiment of this application includes a control component, a plate body and a temperature measuring component. The control component includes a housing, a control main board and an electrical connector. The housing has a first cavity, the control main board is arranged in the first cavity, and the electrical connector is electrically connected to the control main board;

[0006] The plate body includes a heat conducting plate and a heating element arranged on the heat conducting plate. One side of the heat conducting plate close to the housing has an installation part, and the installation part has a second cavity. The heating element is electrically connected to the electrical connector, and the connection part of the heating element and the electrical connector is located in the second cavity; the temperature measuring component is electrically connected to the control main board, and the detection end of the temperature measuring component is arranged in the second cavity.

[0007] The warming plate provided by the embodiment of the present application includes a control component, a plate body, and a temperature measuring component. The control component includes a housing, a control main board, and an electrical connection member. The housing includes a first cavity. The plate body includes a heat conduction plate and a heating element. The heat conduction plate includes a mounting portion, and the mounting portion includes a second cavity. By providing the first cavity for mounting the control main board, by providing the control main board for regulating the heating element, by providing the electrical connection member for connecting the control main board and the heating element, by providing the heating element for heating the heat conduction plate, and then heating or keeping warm the food through the heat conduction plate, by providing the temperature measuring component for detecting the temperature of the heating element, and by providing the second cavity for accommodating the connection part of the electrical connection member and the heating element and the detection end of the temperature measuring component, it is possible to avoid a large temperature difference in the first cavity caused by the heating element and generate condensed water, thereby improving the working reliability of the control main board, and enabling the detection end of the temperature measuring component and the heating element to be in the same space, so that the temperature measuring component can directly sense the temperature of the heating element, and further improving the temperature measurement accuracy of the temperature measuring component.

[0008] In a possible implementation manner, the projection of the first cavity along the thickness direction of the heat conduction plate and the projection of the second cavity along the thickness direction of the heat conduction plate are offset from each other;

[0009] Alternatively, the projection of the first cavity along the thickness direction of the heat conduction plate and the projection of the second cavity along the thickness direction of the heat conduction plate partially overlap.

[0010] With such a setting, the connection part of the electrical connection member and the heating element can be arranged outside the first cavity, so as to avoid a large temperature difference between the inside and outside of the first cavity caused by the heating element, and thus effectively avoid faults such as short circuits of the control main board caused by the generation of condensed water in the first cavity.

[0011] In a possible implementation manner, the plate body further includes a sealing member. One side of the first cavity facing the second cavity has a first opening, and one side of the second cavity facing the first cavity has a second opening. The side of the mounting portion facing the housing is inserted into the first cavity through the first opening, and the sealing member is arranged at the second opening.

[0012] With such a setting, by arranging the sealing member at the second opening, the first cavity and the second cavity can be separated by the sealing member, thereby preventing the heat of the second cavity from being transferred to the first cavity, and thus improving the temperature consistency inside and outside the first cavity. And the side of the mounting portion facing the housing can be inserted into the first cavity. By the cooperation of the mounting portion and the housing, the first cavity can also be closed, and the first cavity can hide the side of the mounting portion, thereby improving the aesthetics of the warming plate.

[0013] In a possible implementation manner, the plate body further includes a fixing member. The connection part of the heating element and the electrical connection member and the detection end of the temperature measuring component are both located in the fixing member, and the detection end of the temperature measuring component abuts between the fixing member and the heating element.

[0014] With such a setting, the connection part between the heating element and the electrical connection component and the detection end of the temperature measurement component can be relatively fixed in the second cavity through the fixing component, thereby preventing relative displacement between the detection end of the temperature measurement component and the heating element, and thus improving the temperature measurement accuracy of the temperature measurement component.

[0015] In a possible implementation manner, the board body further includes a riveting component, and the heating element and the electrical connection component are electrically connected through the riveting component.

[0016] With such a setting, it is possible to prevent the heating element from extending into the first cavity, electrically connect the control main board and the heating element through the electrical connection component, and reliably electrically connect the heating element and the electrical connection component through the riveting component, thereby facilitating the control main board to regulate the heating element.

[0017] In a possible implementation manner, the housing includes a first housing and a second housing connected to each other. The first housing and the second housing jointly define a first cavity, and one side of the heat conduction plate facing the housing is located between the first housing and the second housing.

[0018] With such a setting, the connection between the first housing and the second housing is reliable, and it is convenient to disassemble when the control main board needs to be repaired. Moreover, the side edges of the heat conduction plate can be hidden in the housing, thereby improving the aesthetics of the warm food plate. When storage is required, the heat conduction plate can be rolled up around the housing as an axis.

[0019] In a possible implementation manner, the control component further includes a control switch, and the control switch is arranged on the first housing and is electrically connected to the control main board.

[0020] With such a setting, when the user needs to start or stop the warm food plate or adjust the working temperature of the warm food plate, it can be conveniently operated through the control switch, and then the control main board is triggered through the control switch, so that the control main board controls according to the user's needs.

[0021] In a possible implementation manner, the heating element includes a heating wire, and the heat conduction plate further has a wire routing groove. The heating wire is arranged in the wire routing groove, and both ends of the heating wire are electrically connected to the control main board.

[0022] With such a setting, the heating wire can be arranged circuitously on the heat conduction plate, thereby increasing the heating area of the heating wire, and thus improving the heating efficiency of the heating element. Both ends of the heating wire need to be connected to the control main board to form a circuit. Moreover, the heating wire has better flexibility and is convenient to bend, so it is convenient for the heating wire to be rolled up and stored together with the heat conduction plate.

[0023] In a possible implementation manner, there are two installation parts, and the two installation parts are arranged at intervals along the length direction of the housing. Both ends of the heating wire are respectively located in the two second cavities.

[0024] With such a configuration, the two ends of the heating wire can be respectively located in the two second cavities, the two ends of the heating wire are connected to the two electrical connectors one by one, and the two detection ends of the temperature measuring component or the detection ends of the two temperature measuring components are also respectively arranged in the two cavities, thereby effectively avoiding the heat of the heating element from being transferred to the first cavity, and improving the temperature measurement accuracy of the temperature measuring component.

[0025] In a possible implementation, the temperature conducting plate has a temperature conducting surface, the temperature conducting surface is used to contact with the tableware, and the mounting portion is located on a side of the temperature conducting plate facing away from the temperature conducting surface.

[0026] With such arrangement, when the food warming board is in normal use, the installation portion can be hidden, thereby improving the aesthetics of the food warming board.

The embodiments of this application will be described in detail below with reference to the drawings.

[0042] The terms "first", "second", "third" (if any) in the description, claims and the above-mentioned drawings of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0044] Silicone-based warm food plates mainly use silicone as the panel, and a plastic shell is arranged on the side of the silicone panel. A circuit board is fixed in the plastic shell, and a sealed cavity structure is formed between the plastic shell and the silicone panel. Such silicone-based warm food plates use NTC as the temperature sensing element. In the related art, a cavity can be arranged in the silicone panel, and the NTC is placed in the cavity to sense the temperature of the silicone panel. However, since the NTC has a relatively large temperature sensing lag, the temperature fluctuation of the warm food plate will be relatively large. Or, the heating wire can be extended into the plastic shell, the NTC is also arranged in the plastic shell, and the NTC is pressed on the heating wire. The NTC senses the temperature of the heating wire. Although this method improves the temperature sensing performance of the NTC, since the heating wire generates heat, the temperature inside the plastic shell will increase. When the temperature difference between the inside and outside of the plastic shell is relatively large, condensed water will be formed inside the plastic shell, which will affect the normal operation of the circuit board.

[0045] In view of the above problems, the embodiments of this application provide a warm food plate. By arranging an installation part on the side of the heat conduction plate facing the housing and arranging a second cavity in the installation part, it is convenient to arrange the connection part of the heating element and the electrical connection part and the detection end of the temperature measurement component in the second cavity, which is beneficial to improving the temperature measurement accuracy of the temperature measurement component and preventing the generation of condensed water in the first cavity from causing faults such as short circuit of the control main board, thereby improving the reliability of the control main board.

[0046] The following will describe in detail the specific embodiments of the warm food plate provided by the embodiments of this application with reference to the drawings.

[0047] Refer to Figures 1 to 5 As shown, the warm food plate provided by the embodiments of this application includes a control component 100, a plate body 200 and a temperature measurement component 300. The control component 100 includes a housing 110, a control main board 120 and an electrical connection part 130. The housing 110 has a first cavity 111, the control main board 120 is arranged in the first cavity 111, and the electrical connection part 130 is electrically connected to the control main board 120.

[0048] The plate body 200 includes a heat conduction plate 210 and a heating element 220 disposed on the heat conduction plate 210. One side of the heat conduction plate 210 close to the housing 110 has a mounting portion 211, and the mounting portion 211 has a second cavity 2111. The heating element 220 is electrically connected to the electrical connector 130, and the connection portion between the heating element 220 and the electrical connector 130 is located in the second cavity 2111. The temperature measurement assembly 300 is electrically connected to the control main board 120, and the detection end of the temperature measurement assembly 300 is disposed in the second cavity 2111.

[0049] The warm food plate provided by the embodiment of the present application can be directly used to carry food and directly keep the food warm, or can be used to carry a heat-receptive tableware containing food to indirectly keep the food warm. The embodiment of the present application does not make specific limitations thereto.

[0050] In the embodiment of the present application, the housing 110 is used to install the control main board 120, thereby providing mechanical protection for the control main board 120. The control main board 120 is used to control the start-up and shutdown of the warm food plate and adjust the heating temperature of the warm food plate. The electrical connector 130 is used to electrically connect the control main board 120 and the heating element 220, so that the control signal of the control main board 120 is transmitted to the heating element 220 through the electrical connector 130. The heating element 220 is used to heat the heat conduction plate 210 and perform operations such as keeping the food warm or heating the food through the heat conduction plate 210. The heat conduction plate 210 is used to carry food or tableware containing food, and then transfer the heat of the heating element 220 to the food, so that the warm food plate realizes the heating or heat preservation function for the food. The temperature measurement assembly 300 is used to measure the temperature of the heating element 220 and feedback the detection result to the control main board 120, so as to facilitate the control main board 120 to adjust the power of the heating element 220 in real time according to the detection result, so that the heat conduction plate 210 reaches the required temperature.

[0051] Among them, the heat conduction plate 210 can be a flexible member for easy rolling and storage. For example, the heat conduction plate 210 can be made of flexible materials such as silica gel or rubber.

[0052] To solve the problems existing in the related art, in the embodiments of the present application, the control main board 120 and the heating element 220 are respectively located in different spaces. That is, the control main board 120 is installed in the first cavity 111, and then the control main board 120 and the heating element 220 are electrically connected through the electrical connector 130. The electrical connector 130 does not generate heat when powered on, and the connection part of the electrical connector 130 and the heating element 220 is arranged in the second cavity 2111 of the installation part 211. In this way, the heating element 220 can be excluded from the first cavity 111, and the heating element 220 will not affect the temperature in the first cavity 111, thereby effectively avoiding a large temperature difference between the inside and outside of the first cavity 111, and further effectively avoiding the formation of condensed water in the first cavity 111, so as to avoid the condensed water affecting the normal operation of the control main board 120.

[0053] In addition, to improve the temperature measurement accuracy of the temperature measurement component 300, the detection end of the temperature measurement component 300 can be arranged in the second cavity 2111. In this way, the connection part of the heating element 220 and the electrical connector 130 and the detection end of the temperature measurement component 300 are both located in the second cavity 2111. The detection end of the temperature measurement component 300 and the heating element 220 are in the same space and are arranged adjacent to each other. Furthermore, the temperature measurement component 300 can timely detect the temperature of the heating element 220 without the problem of temperature sensing lag.

[0054] The warm food plate provided by the embodiments of the present application includes a control component 100, a plate main body 200, and a temperature measurement component 300. The control component 100 includes a housing 110, a control main board 120, and an electrical connector 130. The housing 110 includes a first cavity 111. The plate main body 200 includes a heat conduction plate 210 and a heating element 220. The heat conduction plate 210 includes an installation part 211, and the installation part 211 includes a second cavity 2111. By providing the first cavity 111 for installing the control main board 120, by providing the control main board 120 for regulating the heating element 220, by providing the electrical connector 130 for connecting the control main board 120 and the heating element 220, by providing the heating element 220 for heating the heat conduction plate 210, and then heating or keeping warm the food through the heat conduction plate 210, by providing the temperature measurement component 300 for detecting the temperature of the heating element 220, and by providing the second cavity 2111 for accommodating the connection part of the electrical connector 130 and the heating element 220 and the detection end of the temperature measurement component 300, so as to avoid the large temperature difference in the first cavity 111 caused by the heating element 220 and generate condensed water, thereby improving the working reliability of the control main board 120, and making the detection end of the temperature measurement component 300 and the heating element 220 in the same space, and further enabling the temperature measurement component 300 to directly sense the temperature of the heating element 220, and further improving the temperature measurement accuracy of the temperature measurement component 300.

[0055] In some embodiments, the projection of the first cavity 111 in the thickness direction of the heat conduction plate 210 is offset from the projection of the second cavity 2111 in the thickness direction of the heat conduction plate 210.

[0056] Alternatively, in other embodiments, the projection of the first cavity 111 in the thickness direction of the heat conduction plate 210 and the projection of the second cavity 2111 in the thickness direction of the heat conduction plate 210 partially overlap.

[0057] That is to say, whether the projection of the first cavity 111 in the thickness direction of the heat conduction plate 210 and the projection of the second cavity 2111 in the thickness direction of the heat conduction plate 210 are completely offset or partially overlap, as long as the projection of the first cavity 111 in the thickness direction of the heat conduction plate 210 and the projection of the second cavity 2111 in the thickness direction of the heat conduction plate 210 are at least partially offset, the connection part of the electrical connector 130 and the heating element 220 can be arranged outside the first cavity 111, thereby avoiding a large temperature difference between the inside and outside of the first cavity 111 caused by the heating element 220, and effectively avoiding faults such as short circuits in the control main board 120 caused by the generation of condensed water in the first cavity 111.

[0058] Refer to Figure 4 and Figure 5 As shown, in a possible implementation, the board body 200 further includes a seal 230. The side of the first cavity 111 facing the second cavity 2111 has a first opening, the side of the second cavity 2111 facing the first cavity 111 has a second opening, the side of the mounting portion 211 facing the housing 110 is inserted into the first cavity 111 through the first opening, and the seal 230 is arranged at the second opening.

[0059] In this way, by arranging the seal 230 at the second opening, the first cavity 111 and the second cavity 2111 can be separated by the seal 230, thereby preventing the heat of the second cavity 2111 from being transferred to the first cavity 111, and improving the temperature consistency inside and outside the first cavity 111. And the side of the mounting portion 211 facing the housing 110 can be inserted into the first cavity 111. Through the cooperation of the mounting portion 211 and the housing 110, the first cavity 111 can also be closed, and the first cavity 111 can hide the side of the mounting portion 211, thereby improving the aesthetics of the warm dish board.

[0060] Refer to Figure 4 and Figure 5 As shown, in some embodiments, the board body 200 further includes a fixing member 240. The connection part between the heating element 220 and the electrical connector 130 and the detection end of the temperature measuring component 300 are both located inside the fixing member 240, and the detection end of the temperature measuring component 300 abuts between the fixing member 240 and the heating element 220.

[0061] In this way, the connection part between the heating element 220 and the electrical connection member 130 and the detection end of the temperature measurement component 300 can be relatively fixed in the second cavity through the fixing member 240, thereby preventing relative displacement between the detection end of the temperature measurement component 300 and the heating element 220, and thus improving the temperature measurement accuracy of the temperature measurement component 300.

[0062] Among them, the fixing member 240 can be a sleeve, and the sleeve can be made of a flame-retardant material, thereby improving the safety performance of the warm dish board.

[0063] Referring to Figure 4 As shown, in a possible implementation manner, the board body 200 further includes a riveting member 250, and the heating element 220 and the electrical connection member 130 are electrically connected through the riveting member 250.

[0064] In this way, it can be avoided that the heating element 220 extends into the first cavity 111, and the control main board 120 and the heating element 220 are electrically connected through the electrical connection member 130, and the heating element 220 and the electrical connection member 130 are reliably electrically connected through the riveting member 250, thereby facilitating the control main board 120 to regulate the heating element 220.

[0065] Referring to Figure 2 And Figure 5 As shown, in specific implementation, the housing 110 includes a first housing 112 and a second housing 113 that are connected to each other. The first housing 112 and the second housing 113 jointly define a first cavity 111, and the side of the heat conduction plate 210 facing the housing 110 is located between the first housing 112 and the second housing 113.

[0066] In the above setting manner, due to the needs of processing and assembly, the housing 110 can be set as two parts, that is, the housing 110 includes a first housing 112 and a second housing 113. Among them, the first housing 112 and the second housing 113 can be connected by a threaded manner to make the connection between the first housing 112 and the second housing 113 reliable and convenient for disassembly when the control main board 120 needs to be repaired. After the first housing 112 and the second housing 113 are connected, a first cavity 111 for installing the control main board 120 can be formed inside the housing 110.

[0067] In order to facilitate storage and improve the aesthetics of the warm dish board, the side of the heat conduction plate 210 facing the housing 110 can be inserted between the first housing 112 and the second housing 113, and then through the connection of the first housing 112 and the second housing 113, the side of the heat conduction plate 210 can be fixed between the first housing 112 and the second housing 113. The side of the heat conduction plate 210 can be hidden inside the housing 110, thereby improving the aesthetics of the warm dish board. When storage is needed, the heat conduction plate 210 can be rolled up with the housing 110 as the axis.

[0068] Referring toFigure 5 As shown in Figure 6 Figure 5 , in a possible implementation, the control component 100 further includes a control switch 140. The control switch 140 is disposed on the first housing 112 and is electrically connected to the control main board 120.

[0069] With such a setting, when the user needs to start or stop the warming plate or adjust the working temperature of the warming plate, the operation can be conveniently performed through the control switch 140, and then the control main board 120 is triggered through the control switch 140, so that the control main board 120 performs control according to the user's needs.

[0070] Among them, the control switch 140 can be a push type, a rotary type or a touch type, and the embodiments of the present application do not specifically limit this.

[0071] Referring to Figure 3 As shown in Figure 4 Figure 3 , in some embodiments, the heating element 220 includes a heating wire 221. The heat conduction plate 210 further has a wire groove 212. The heating wire 221 is disposed in the wire groove 212, and both ends of the heating wire 221 are electrically connected to the control main board 120.

[0072] In this way, the heating wire 221 can be arranged in a meandering manner on the heat conduction plate 210, thereby increasing the heating area of the heating wire 221, and further improving the heating efficiency of the heating element. Both ends of the heating wire 221 need to be connected to the control main board 120 to form a loop. And the heating wire 221 has better flexibility and is easy to bend, so that it is convenient for the heating wire 221 to be rolled up and stored together with the heat conduction plate 210.

[0073] In a possible implementation, there are two mounting parts 211. The two mounting parts 211 are arranged at intervals along the length direction of the housing 110, and both ends of the heating wire 221 are respectively located in the two second cavities 2111.

[0074] It can be understood that when the heating element 220 uses the heating wire 221, since both ends of the heating wire 221 need to be connected to the control main board 120, two mounting parts 211 are arranged at intervals along the length direction of the housing 110 to form two second cavities 2111. In this way, both ends of the heating wire 221 can be respectively located in the two second cavities 2111. Both ends of the heating wire 221 are respectively connected to the two electrical connectors 130 in one-to-one correspondence, and the two detection ends of the temperature measurement component 300 or the detection ends of the two temperature measurement components 300 are also respectively arranged in the two cavities, so as to effectively avoid the heat of the heating element 220 being transferred to the first cavity 111 and improve the temperature measurement accuracy of the temperature measurement component 300.

[0075] Referring to Figure 2 , Figure 5 As shown in Figure 6As shown, in some embodiments, the temperature conducting plate 210 has a temperature conducting surface 213 , which is used to contact with tableware, and the mounting portion 211 is located on a side of the temperature conducting plate 210 away from the temperature conducting surface 213 .

[0076] It can be understood that the temperature conducting surface 213 is the surface for directly supporting food or tableware containing food. When the warming board is placed on the dining table, the side of the warming board with the temperature conducting surface 213 is the appearance surface. Improving the aesthetics of the temperature conducting surface 213 can improve the aesthetics of the warming board. Therefore, the mounting portion 211 is arranged on the side of the temperature conducting plate 210 away from the temperature conducting surface 213. When the warming board is in normal use, the mounting portion 211 can be hidden, thereby improving the aesthetics of the warming board.

[0077] Reference Figure 3 As shown, in addition, in order to improve the supporting performance and structural strength of the heat conduction plate 210, a plurality of supporting feet 214 can be set on the side of the heat conduction plate 210 away from the heat conduction surface 213. The supporting feet 214 can stably support the heat conduction plate 210 on the table top, and make the heating element 220 have a certain height away from the table top, thereby facilitating the heat dissipation of the warming plate.

[0078] In a possible implementation, a projection of the heat-generating element 220 along the thickness direction of the heat-conducting plate 210 and a projection of the first cavity 111 along the thickness direction of the heat-conducting plate 210 are staggered.

[0079] Such a configuration can ensure that when the mounting portion 211 is inserted into the first cavity 111 toward one side of the shell 110, the connection portion between the heating element 220 and the electrical connector 130 is still located outside the first cavity 111, thereby effectively isolating the heating element 220 and the control main board 120, thereby improving the temperature consistency inside and outside the first cavity 111, thereby effectively avoiding the generation of condensed water in the first cavity 111.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
