New description: 【New technical field】 This creation department is about a food insulation table with heating device, especially a food insulation table with uniform heat source, which can increase the safety of use and the heating element is less prone to failure. The utility model has the advantages of long service life and uniform heat dissipation, so as to uniformly heat the food to achieve the heat preservation effect. [Prior Art] For places that need to provide a large number of meals, such as companies, factories, or cafeterias that provide employees for lunch and dinner, in order to meet the needs of many diners in a short period of time, usually a large amount of food is cooked at once. Well, use food insulation equipment to keep the food warm; especially in the low temperature season, if the food is not warm after the fork, it is easy to quickly become cold and affect the flavor and also affect the health of the diet, so cook from food. The insulation between before eating is very important. Referring to the first design of the food holding station 10, the conventional food holding station 10 uses an electric heating tube u having a very high surface temperature as a heat source, and the food heat insulating box 18 for containing food can be discharged on the upper layer of the food holding station 10, In the case where the heating of the food directly by the electric heating officer 11 is too concentrated, a water storage tank 12 is provided below the food heat preservation box 18, and after the water is placed in the water storage tank 12, the water is heated by the electric heating pipe 11 to generate water. Vapor, which provides a relatively uniform heating temperature through high temperature water vapor for food insulation. The multi-test 2 is a design of the conventional food warming table 20, which is substantially the same as the design of the first figure, but the gas stove 21 is used as a heat source to heat the fresh water stored in the water storage tank 22 to generate water vapor for food insulation. . M290668 仁苐1图知知食品保温台1 The electric heating tube used in Q 1 1 ♦ The surface is extremely directional, it is easy to burn when used, and the safety of use is poor. If the water in the water storage tank 12 is exhausted, it is not replenished in time. The electric heating tube is easy to be destroyed by overheating, and the oil smoke is inevitably generated during the heating and heat preservation process of the food, so that the electric heating tube u is greased and not easily cleaned, and the electric heating tube 11 is made of metal material, and the long time door is immersed in water and heated. The surface is prone to rust, which not only deteriorates thermal efficiency but also easily breaks down. In the second figure, although the gas warming table 20 uses the gas stove 21 as a heat source, the temperature is not as easy to control as the electric heat pipe u, and the fire of the gas stove 21 is used in the guest's numerous restaurants and unattended. Food insulation, such as the fire in the fire to extinguish the gas leak, may cause greater danger. Referring to Figure 3, the design of the food warming stove 30 is also used as a food heat preservation heating, and is often used in a western restaurant to directly store the food in the alcohol stove 31 using the solid/xenon as a heat source. The food in the box 38 is heated and kept warm, and not only has the disadvantage that the heat source is too concentrated, the heating is uneven, and the alcohol stove 31 may be dumped due to dumping of the alcohol fuel, which may cause a fire hazard. In addition, the conventional food holding tables 10 and 20 which use water to heat the water to generate water vapor are prone to condensation water condensed in the upper food heat preservation box 18, and for foods which need to be kept dry, such as crispy fried foods, such as contamination Water will also affect the food. , τ, above, the food holding station 1〇, 20, 30, which is equipped with a heating device to provide food heating and heat preservation effect, has the following disadvantages: 1. The surface temperature of the electric heating tube 11 is extremely high, and it is easy to use. The scald is dangerous. The gas stove 21 may cause the fire to extinguish the gas leakage when unattended. The M290668 and the 酉 酉 31 may also cause the risk of fire. 2. Because the electric heating tube U is immersed in water for a long time, it is easy to rust and is also prone to oil/loss. Not only does it affect thermal efficiency, but it is also prone to failure. 3. Water vapor is generated from the heated water system to provide food insulation. The town can affect the food because of the condensed water contaminated with food. By heating the clean water to generate high-temperature steam to keep the food warm, the energy is indirectly used to heat the food, and the water vapor may be dissipated and wasted, so the energy utilization efficiency is poor. 5. If the food is directly heated by the alcohol stove 31, the heat source is too concentrated, and there is a disadvantage that the heating is uneven. 6. In order to provide a more uniform heat source for heating and heat preservation, the conventional food holding station=20 needs to have the water storage tanks 12 and 22, so the food holding station 1〇, 2〇 needs to have a high height, and also needs to use more. Material manufacturing. [New content] This creation is based on the thin and flat plate heating plate as the heat source for uniform heating of the food insulation table, and the power supply control device provides power switch and temperature adjustment control as a food insulation table with heating and heat preservation functions. Solve the problem that the design of the food insulation table is dangerous, easy to malfunction, easy to affect the food, the energy efficiency is poor, the heating is uniform, and the _ multi-material manufacturing is required. This creation consists of a suitably sized body made of a suitable material... or a plurality of flat heating plates, a power control device, which may be a closed phase body or an opening above which can hold a food cooler. The flat-shaped hair M290668 hot plate has an electric heating body layer capable of generating a heat source, and two insulating sheets covering the electric heating body layer and dissipating the heat generating source to form a heat generating unit, so that the heat source of the hot body layer can be uniformly distributed. Keep food warm. The flat heating plate has a thickness of only 1 mm and can be made into various sizes of different lengths and widths, so that it can be mounted on any of the inner surfaces of the lower, left, right, front, and rear sides of the space under the food heat preservation box of the food warming table. Or directly mounted on the upper surface of the closed food insulation rib. The effect of this creation is that the thickness of the heat source used is extremely thin, does not occupy the space for food preservation, the surface temperature of the heat source is low, and it will not be burned. The use of Anwang 1* raw, the heat source has a large heating area and uniform temperature, and can be effectively heated. Insulation; direct heating method to heat food, no need to heat water to produce water vapor t-type indirect heating food, high energy utilization efficiency; and the heat source surface is easy / monthly, long service life is not easy to malfunction, for foods that are easy to produce soot The use is extremely suitable. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Referring to FIG. 4, a preferred embodiment of the food holding station of the present invention comprises a body 40, a flat heating plate 41, and a power control device 42. The power supply device 42 is connected to the flat heating plate by wires. 41, for controlling the heating temperature to heat and hold the food contained in the food heat preservation box 18. Referring to Figures 5 and 6, each of the flat heating plates 41 has an electric heating layer 45' which generates heat. The electric heating layer 45 is joined to each other by a long copper box 47 for conducting electricity and heat. The electric heating layer 45 and the elongated copper foil 47 are sealed by a pressure bonding method, and the two insulating sheets 46 of the heat source are dispersed. In this embodiment, the electric heating layer 45 is a conductive heat-generating graphite layer which can be uniformly applied to the bonding faces of the two insulating sheets 46 by screen printing. In this embodiment, the insulating sheet 46 is a glass fiber which is resistant to high temperature, pressure, acid and alkali, cold and heat, impact, elasticity and easy to clean. The crucible is mainly used to protect the electric heating layer 45 and conduct heat energy. . Since the thickness of the flat heating plate 41 is relatively thin, the thickness of the insulating sheet 46 and the electric heating layer 45 is less than 1 mm, which is like a piece of cardboard. Therefore, the installation in the prism 40 does not occupy the food in the table 40. The space of the casing 18 and the length and width of the flat heating plate 41 can be made to match the inner space and the inner surface of the base 4, so that the flat heating plate 41 can be mounted in one or most of the bases 40. surface. Since the electric heating body layer 45 is uniformly distributed in a planar shape, the flat heating plate 41 has a large heat generating area, and the flat plate is equivalent to the heating power of the electric heating tube u, the gas furnace 21 or the alcohol furnace 31. The surface temperature of the heating plate 41 per unit area can be relatively reduced to avoid the risk of being burned during use, and the large heating area and the elasticity that can be mounted on any inner surface of the inside of the table body 4 can also make the inside of the table body 40 The temperature is relatively uniform. When the power supply is supplied to the flat heating plates 41, the electric heating layer 45 of the flat heating plate 41 generates heat and generates heat, and the heating heat is dissipated through the insulating sheets 46. The heating temperature of the flat heating plate 41 can be By adjusting the power control device 42, the food in the food heat preservation box is placed in the table body 4〇9 M290668 to uniformly connect the heat energy to achieve a good heat preservation effect without causing the food due to the local excessively high heating temperature. The insulating sheet 46 on the surface of the flat heating plate 41 has the characteristics of being resistant to 3 knots and being cleaned, and is installed on the inner side of the table 4 as a food warming table, and is easy to clean when contaminated with food oil, and does not cause The flat heating plate 41 is damaged by the erosion of the oil smoke due to long-term use. Referring to FIG. 7, a second preferred embodiment of the present invention, the preferred embodiment (4)-table food holding station includes a body 5G, a flat heating plate 4 - a power control device 52, the tablet The structure of the heating plate 41 is the same as that of the first preferred embodiment, and is directly mounted on the upper surface of the table 5 to place the table 50 on the table top of the general table 53. The food heat box 18 is placed directly on the plate. The surface of the heat generating plate 41 can be used as food for heat preservation and heating. Since the heat source design of the preferred embodiment also has the advantages of relatively low temperature and no occupation of the internal space of the base 50, the desktop food warming table of the present embodiment can have a thin body 5G design and is placed on a general table. When the surface of the 53 is used on the surface, the table top of the table 53 is not burned, and there is no danger that the high/JDL electric heater 11, the gas furnace 21 or the alcohol stove 31 may be used. According to the above description, the food holding table of the present invention has the following advantages: 1. Since the thickness of the flat heating plate 41 is relatively thin, the thickness is only 1 mm, which is like a piece of cardboard, so when installed in the creative food holding table = Do not occupy the space in the creation of the food insulation table, so that the production materials can be more elegant. • At the same power, the flat heating plate 41 has a relatively large area, so that the temperature per unit area is relatively reduced, and the heat energy emitted is still M290668: the effect of heating and heat preservation of the food is achieved, but the local temperature is not It is too high, so it will not burn when used, which will improve the safety of use. 3. Since the flat heating plate 41 used in the present invention is relatively thin, and the length and width dimensions can be elastically changed as needed, it can be mounted on any surface of the joint or even mounted on the upper surface of the closed base body, and The flat heating plate 41 has a large heating area, and the heating temperature is uniform. Therefore, the food of the creation=the temperature of the warming table is uniform, and when used as a food warming table, the food heated and heated can have a relatively uniform heating temperature. Uniform insulation effect: It can maintain the deliciousness of food and improve the practicality of use. 4. Since the flat heating plate 41 provides food heat preservation such as heat in a dry heat manner, there is no disadvantage that the conventional food heat preservation table may heat the food by heating to generate water vapor, which may cause condensation to fall into the food. Therefore, this creation can maintain the delicious food and improve the practicality of use. 5. Since the flat heating plate 41 can withstand high temperature, pressure, acid and alkali resistance, humidity resistance, cold and heat resistance, impact resistance, elasticity, long service life and easy π rationality, the present invention is used for heating and heat preservation. In the food process, even if the flat heating plate 41 is contaminated with oil smoke and dirt, it can be easily cleaned to maintain good heat conduction, which can save energy and is not easy to malfunction. The above description is only a preferred embodiment of the present invention, and it is not limited to the scope of the present invention, that is, the simple equivalent change made by the patent application and the content of the new patent specification. And the modifications should still be within the scope of this new patent. 11 M290668 [Simple description of the drawings] Figure 1 is a perspective view of a general food insulation table; Figure 2 is a perspective view of a general food insulation table; Figure 3 is a perspective view of a general food insulation furnace FIG. 4 is a perspective view showing a first preferred embodiment of the present invention; FIG. 5 is a perspective view showing the structure of the flat heating plate used in the first preferred embodiment, comprising an electric heating layer, Figure 6 is a cross-sectional view showing the structure of the flat heating plate used in the first preferred embodiment, comprising an electric heating layer, two copper foils and two insulating sheets; A perspective view illustrating a second preferred embodiment of the present creation.
