Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to an electric heating dining table structure. Background Technology

[0002] As users demand higher levels of dining comfort and food quality, electric heated dining tables are gradually becoming mainstream. Their core principle involves laying heating elements, such as heating films or heating wires, on the surface or inside the tabletop. When electricity is applied, heat is transferred to the tabletop, heating and keeping the food trays on it warm. Currently, commercially available tables generally use a design where the heating elements fully cover the tabletop, ensuring that food trays placed anywhere on the tabletop are heated evenly. However, this design has some problems: food needs to be kept warm at 40℃-60℃, but at this temperature, the edge of the table where the user's elbow rests will feel hot and may even cause burns; if the temperature drops to 30-35℃, the food cannot be kept warm effectively, especially in low-temperature or long-term dining scenarios, it is easy to cool and spoil, thus creating a problem of not being able to maintain the right temperature; poor user experience: when eating, resting elbows on the edge of the table is a natural posture, and high temperatures force users to deliberately avoid or adjust their sitting posture, increasing fatigue, which is not friendly to sensitive groups such as the elderly and children, limiting its applicability; energy waste: the full-coverage design causes the heating elements in non-food areas to consume electricity ineffectively, which does not conform to the trend of energy conservation and environmental protection, and increases the user's electricity costs.

[0003] In conclusion, the existing electric heated dining table structure suffers from poor user experience and high energy consumption due to its full-coverage design, and therefore needs to be improved. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-4 An electric heating dining table structure includes table legs 20 connected to a tabletop 10 and heating elements. The tabletop 10 includes a panel mounted on a support plate. The table legs 20 are connected to the support plate. The panel is equipped with an induction cooker 70 for cooking food, a food warming area 100, and a hand warming area 110. The induction cooker 70 is located in the middle of the panel, the hand warming area 110 is located on the outer side of the panel, and the food warming area 100 is located between the induction cooker 70 and the hand warming area 110. The heating elements include a first heating element 300 and a second heating element 310. The food warming area 100 includes the first heating element 300 located below the panel, and the hand warming area 110 includes the second heating element 310 located below the panel. The temperature of the food warming area 100 is higher than the temperature of the hand warming area 110. The induction cooker 70 is embedded in the middle of the panel. A central controller 50 is electrically connected to the first heating element 300 and the second heating element 310.

[0026] In this embodiment, the tabletop 10 can be made of sintered stone, granite, or ceramic.

[0027] In practice, the first heating element 300 and the second heating element 310 can be respectively positioned below the corresponding positions on the panel.

[0028] The lower part of the panel is provided with mounting slots for mounting a first heating element 300 and a second heating element 310. The first heating element 300 and the second heating element 310 respectively include an electric heating film, a reflector, and an insulation board. The electric heating film is attached to the surface of the mounting slot. The reflector is disposed between the electric heating film and the insulation board. The insulation board seals the opening of the mounting slot and is pressed against the support plate.

[0029] In this embodiment, the heating element further includes a third heating element 40.

[0030] A third heating element 40 is provided on the table leg 20, and the central controller 50 is electrically connected to the third heating element 40.

[0031] The table leg 20 has an installation space 200 inside, and the surface of the table leg 20 has a vent 210 that communicates with the installation space 200; the third electric heating element 40 is disposed in the installation space 200; the third electric heating element 40 includes an electric heating film 410, an emitting plate 420, and an insulation plate, and the electric heating film 410 is disposed in the installation space 200 between the emitting plate 420 and the vent 210.

[0032] In this embodiment, the mounting space 200 inside the table leg 20 provides a stable mounting carrier for the third electric heating element 40, preventing the third electric heating element 40 from being exposed to the outside and subjected to collisions and wear, thus playing a protective role; the vent 210 on the surface of the table leg 20, which communicates with the mounting space 200, can smoothly conduct the heat generated by the third electric heating element 40 when it is working in the mounting space 200, so that the heat can act on the surrounding area of ​​the table leg 20, helping to achieve an auxiliary heating effect.

[0033] In the third electric heating element 40, the electric heating film 410 is the core heating component. After being powered on, it can generate heat and provide an auxiliary heating source for the area around the table leg 20. The emitter plate 420 is located on the side of the electric heating film 410 away from the vent 210. It can reflect the heat diffused from the electric heating film 410 into the interior of the table leg 20, reduce heat loss, and allow more heat to be discharged through the vent 210, thereby improving the energy efficiency ratio of the product.

[0034] When in use, first connect the central controller 50 to the external power supply. At this time, the central controller 50, which is electrically connected to the first heating element 300, the second heating element 310, and the third heating element 40, enters the standby state. The user can trigger the working commands of each heating element through the operation interface of the central controller 50, such as buttons and knobs.

[0035] For different functional areas of the tabletop 10, the heating elements work together: the first heating element 300 in the food warming area 100 starts to heat up after receiving the start signal from the central controller 50. The heat generated is directly transferred to the panel of the food warming area 100 to keep the cooked food in the plate placed in this area warm and maintain the cooked food at a suitable temperature for eating; the second heating element 310 in the hand warming area 110 outside the food warming area 100 is powered on synchronously or independently after receiving the start command from the central controller 50. The heat generated keeps the panel of the hand warming area 110 at a comfortable temperature for human contact, meeting the user's need for elbow placement while eating and avoiding discomfort from high temperature.

[0036] Meanwhile, the third electric heating element 40 on the table leg 20 can be activated or deactivated according to user needs under the control of the central controller 50. Once activated, the heat generated can be applied to the area around the table leg 20 to help raise the local temperature of the dining environment, thus helping to warm the legs and further optimizing the user experience.

[0037] It should be noted that the central controller 50 in this solution is existing technology, and the control principle it adopts is the mature electrical control logic in the industry. It receives user operation signals through internally preset circuit modules (such as relays, microcontrollers, etc.), and then converts the signals into electrical control commands, which are transmitted to the first heating element 300, the second heating element 310, and the third heating element 40 respectively. This enables independent or linkage control of the opening and closing states of each heating element. There is no need to add special control structures or innovative control algorithms. The existing mature control technology is sufficient to meet the functional requirements of the equipment.

[0038] The table leg 20 includes a side plate connected to its base plate, which is located below the electric heating film 410 and the emitting plate 420. At least one side plate has a movable plate 201 hinged to the base plate on one side at its lower part, and a movable locking plate 60 for pressing and locking the movable plate 201 on the opposite side at its upper part.

[0039] In this embodiment, the user can rotate the movable locking plate 60 to open or close the movable plate 201, which greatly facilitates the later maintenance of the product.

[0040] A bracket is provided on the base plate, and a Bluetooth active speaker is provided on the bracket. A heat insulation plate is provided between the Bluetooth active speaker and the transmitter plate 420.

[0041] The installation space 200 is provided with a support frame connected to the bracket. The support frame is provided with the emitting plate 420, the heat insulation plate and the electric heating film 410 on the side facing the vent 210, and the heat insulation plate is provided on the other side of the support frame. The area enclosed by the vent 210 is larger than the area of ​​the emitting plate 420 or the electric heating film 410.

[0042] In this embodiment, the user's mobile phone connects to a Bluetooth active speaker via Bluetooth, which can play audio files, such as songs, from the user's mobile phone, providing a better dining environment for the user.

[0043] The central controller 50 is fixedly mounted on the surface of one side of the tabletop 10. The central controller 50 is equipped with a power switch button and control buttons for controlling whether the first heating element 300, the second heating element 310 and the third heating element 40 work.

[0044] In everyday scenarios such as spilled soup during meals or wiping the tabletop with water, liquids such as soup on the tabletop are unlikely to directly contact the central controller located below. This effectively prevents liquids from seeping into the central controller, thus preventing short circuits and damage caused by liquid seepage and ensuring the stable operation of the central controller and the overall structure of the electric heated dining table.

[0045] The table legs 20 are provided in two pairs and are spaced apart on the left and right, or the table legs 20 are provided in the middle and are in the form of a columnar structure or a ring structure.

[0047] The hand warming area 110 is provided in two places and is respectively provided on the tabletops 10 on the front and back sides of the food warming area 100, or the hand warming area 110 is provided in four places and is respectively provided on the tabletops 10 on the front, back, left and right sides of the food warming area 100; and / or the table legs 20 are provided in two places and are spaced apart on the left and right sides, or the table legs 20 are provided in the middle and are in the form of a columnar structure or a ring structure.

[0048] In a first embodiment of the hand-warming area 110, two hand-warming areas 110 are provided, respectively located on the front and rear sides of the tabletop 10 of the food-warming area 100. This design is suitable for scenarios where the main seating arrangement at the dining table is in the front-to-back direction, accurately covering the elbow resting areas of users sitting in front and behind, meeting the comfort and heating needs of the core users; at the same time, it avoids setting up additional heating structures in non-high-frequency sitting areas such as the left and right sides, reducing ineffective energy consumption, and balancing practicality and energy saving.

[0049] In a second embodiment of the hand-warming area 110, four hand-warming areas 110 are provided, respectively located on the tabletops 10 in front of, behind, and to the left and right of the food-warming area 100. This design is suitable for scenarios where multiple people sit around a table, fully covering the elbow resting areas of users sitting in all directions, meeting the comfort and heating needs of all diners; at the same time, heating structures are only provided in high-frequency sitting areas to avoid energy waste, balancing practicality and energy efficiency in all scenarios.

[0050] The table legs 20 have a columnar or ring-shaped structure, such as Figure 1 As shown, this design fits the second embodiment of the hand-warming area 110. This design ensures effective heating of the elbow areas of users seated in all directions, while its columnar / ring-shaped stability reliably supports the tabletop 10, balancing practicality in heating with stability.

[0051] The table legs are designed with two legs, spaced apart on the left and right, such as... Figure 2 As shown, the tabletop 10 is stably supported by the left and right spacing structure, while avoiding the front and rear hand warming areas 110, so as not to block the heat transfer in the area, ensuring the heating effect of the elbow resting area of ​​the users sitting in front and behind, and taking into account both the reliability of support and the practicality of heating.
