Description
Technical Field
[0001] The utility model relates to the technical field of heat preservation dining tables, in particular to a heat preservation dining table device. Background Art
[0002] Being able to eat hot meals is a very enjoyable thing for people. However, after the cooked meals are placed on the table, they quickly cool down. Especially in cold weather, it is difficult for people to enjoy hot meals. Therefore, there is a need for a dining table that can keep the meals warm, so as to keep the temperature of the meals on the table, which not only maintains the taste of the meals, but also warms the stomach of the user. At present, some insulated dining tables use electric heating wires to heat water so that the water vapor heats and keeps the meals on the table warm. However, the electric heating wires are in direct contact with water, which is prone to safety problems. There is also a method of using heat-conducting oil to keep the meals warm.
[0003] For example, in the Chinese patent with publication number CN111265013B, a dining table capable of keeping food warm is disclosed to include a tabletop, an electromagnetic heating module, an electric heating ring, a partition, heat transfer oil and a heat preservation cover. The bottom of the tabletop is provided with table legs. The tabletop is divided into a main heat preservation area and auxiliary heat preservation areas located on both sides of the main heat preservation area. The main heat preservation area and the auxiliary heat preservation area are separated by a partition. The tabletop includes a glass layer and a heat preservation layer. In the invention, the tabletop is set as the main structure of the glass layer and the heat preservation layer. Heat transfer oil is filled between the glass layer and the heat preservation layer. The tabletop can be heated by controlling the heating element to heat the heat transfer oil. The food placed on the tabletop can be kept warm by cooperating with the heat preservation cover. In the actual production process, the heat transfer oil is injected between the glass layer and the heat preservation layer. If it is used for a long time and is not replaced with a new one, the expansion tank will be overheated, and the oil loss will increase. At the same time, it may also cause the coil to be damaged or damaged. Therefore, a heat preservation dining table device with a simple structure, convenient use and effective reduction of daily maintenance frequency is needed. Utility Model Content

The surface temperature of the heat conducting plate 4 made of metal increases and further transfers the heat to the dishes that need to be kept warm. If the external temperature is low, the heat transfer and heat preservation effect of the heat conducting plate 4 is reduced. At this time, the heat conducting plate 4 can be removed and placed on one side of the table leg 2, and the heat preservation cover 5 is taken out to cover the top of the heat preservation cavity 12. The open side of the heat preservation cover 5 is placed on the side close to the fan group 6. The dishes that need to be kept warm are directly placed in the bottom of the heat preservation cavity 12. The fan group 6 blows out high-temperature gas from the heating cavity 11, and the high-temperature gas enters the space formed by the heat preservation cavity 12 and the heat preservation cover 5, effectively isolating the external low-temperature gas, so that the temperature of the dishes can be maintained for a long time. The heat preservation of dishes in various situations can be achieved by removing the heat conducting plate 4. The overall structure is compact and easy to use. The air duct cavity 13 and the fan group 6 accelerate the flow of hot air between the heating cavity 11 and the heat preservation cavity 12. Daily maintenance can be completed by opening the heat conducting plate 4.
[0025] In this embodiment, a fan group 6 is provided on one side of the two groups of air duct cavities 13 close to the insulation cavity 12, and the fan group 6 is fixedly connected to the side walls of the two groups of air duct cavities 13. The fan group 6 structure is adopted, and the side walls of the fan group 6 are fixedly connected to the side walls of the air duct cavity 13 by screws. If a fault occurs or the air outlet is blocked during use, the user can open the heat conduction plate 4 to perform daily maintenance on the fan group 6 to ensure that the high-temperature gas is blown out stably.
[0026] In this embodiment, a temperature rising groove 41 and a reinforcing rib 42 are provided at the bottom of the heat conducting plate 4. The reinforcing rib 42 is provided in the middle of the temperature rising groove 41 and cooperates with the support of the heat preservation cavity 12. The temperature rising groove 41 structure effectively reduces the distance between the surface of the heat conducting plate 4 and the high-temperature gas, making the heat transfer effect faster, while reducing the material used for the heat conducting plate 4 and reducing the production cost. The reinforcing rib 42 structure located in the middle is used to strengthen the supporting effect of the heat conducting plate 4 to avoid concave tilt caused by excessive weight of the dishes.
[0027] In this embodiment, the heat conducting plate 4 is made of metal.
[0028] In this embodiment, slide grooves 14 are respectively provided on both sides of the table body 1, and the inner side of the thermal insulation cover 5 is correspondingly provided with slide bars 51 that slide with the two groups of the slide grooves 14. The two groups of slide bars 51 are corresponding to the sides that contact the two groups of the slide grooves 14 and are chamfered. The thermal insulation cover 5 is recovered by the slide grooves 14 and the slide bars 51, so that the overall structure of the table body 1 is compact, and the site space occupied by the thermal insulation cover 5 when it is folded is effectively reduced.
[0029] In this embodiment, a non-slip pad 52 is provided on the side of the insulation cover 5 that contacts the table body 1. The non-slip pad 52 is made of rubber. The non-slip pad 52 has a large friction when in contact with the table top, so that the insulation cover 5 can cover the top of the insulation cavity 12 more stably and effectively, forming an insulation space to keep the dishes warm.
[0030] In this embodiment, a heat insulation plate 15 is provided in the heating chamber 11, and the heat insulation plate 15 is arranged between the bottom of the heating chamber 11 and the heating module 3. The heat insulation plate 15 arranged below the heating module 3 isolates part of the heat transferred downward, avoids accidentally touching the bottom of the table body 1 during heat preservation and heating, and causes burns to the user, thereby improving safety during use.
[0031] In this embodiment, the upper surface of the heat conduction plate 4 is provided with a clearance hole 43 and a lifting plug 44, the lifting plug 44 is interference fit with the clearance hole 43, the inner diameter of the clearance hole 43 is larger than the entrance diameter, the lifting plug 44 includes a plug body and a handle, the plug body is squeezed and pushed into the clearance hole 43 when installed, the plug body is interference fit with the inside of the clearance hole 43, the handle extends out of the clearance hole 43, and the heat conduction plate 4 is separated from the insulation chamber 12 by slightly pulling the handle, which is easy to use. When the lifting plug 44 is not needed frequently, the heat conduction plate 4 can be pressed and the handle can be pulled to make the plug body fall out of the clearance hole 43. At this time, the surface of the desktop is flat, which is convenient for daily use.
[0032] In this embodiment, the lifting plug 44 is made of rubber.
[0033] In this embodiment, the table leg 2 is provided with a hook 7, and the bottom surface of the heat conducting plate 4 is provided with a hanging groove 45 which cooperates with the hook 7. The inner side of the hanging groove 45 is provided with a limiting groove, and the limiting groove cooperates with the protruding end of the hook 7. The hook 7 cooperates with the limiting groove structure to hang the heat conducting plate 4 on the side of the table leg 2, without occupying additional space for placing the heat conducting plate 4.
[0034] The working principle of this utility model:
[0035] When the on button of the heating module 3 is pressed, the temperature of the heating plate in the heating chamber 11 rises rapidly, the gas in the heating chamber 11 heats up and expands, and is poured into the insulation chamber 12 under the guidance of the fan group 6, and the high-temperature gas transfers the heat to the heat conducting plate 4. The surface temperature of the metal heat conducting plate 4 increases and further transfers the heat to the dishes that need to be kept warm. If the external temperature is low, the heat transfer and insulation effect of the heat conducting plate 4 is reduced. At this time, the heat conducting plate 4 can be removed and placed on one side of the table leg 2, and the insulation cover 5 is taken out and covered on the top of the insulation chamber 12. The open side of the insulation cover 5 is placed on the side close to the fan group 6, and the dishes that need to be kept warm are directly placed at the bottom of the insulation chamber 12. The fan group 6 blows out high-temperature gas from the heating chamber 11, and the high-temperature gas enters the space formed by the insulation chamber 12 and the insulation cover 5, effectively isolating the external low-temperature gas, so that the temperature of the dishes can be maintained for a long time.
