Description

Technical Field

[0001] This utility model relates to the field of heat preservation furnace technology, and in particular to an anti-sticking heat preservation furnace. Background Technology

[0002] A food warming oven is a device used to maintain the temperature of food and ensure that the food retains its taste and quality for a certain period of time.

[0003] Chinese Patent Application No. CN202210568285.3 discloses a food warming device and its key components, along with processing equipment and methods. The device involves placing a food container connected to a heat conductor directly into the appliance placement cavity of the warming furnace. The bottom of the heat conductor abuts against the upper surface of the heating shell. The heating element heats the heating shell, and the heat is conducted through the heat conductor to the food container, thus keeping the food warm. However, this warming device relies on direct combustion of the fuel at the bottom of the furnace surface. The furnace surface material is directly heated, resulting in uneven heating—higher temperature at the center and lower temperature at the edges—which can easily lead to scorching or burning during use. Utility Model Content

[0004] The main purpose of this utility model is to provide an anti-sticking and heat-preserving furnace to solve the problem in related technologies where the combustible material acts directly on the bottom of the furnace surface, and the furnace surface material is directly heated, resulting in high temperature at the center of the furnace surface and low temperature at the edges, leading to uneven heating.

[0005] To achieve the above objectives, according to one aspect of the present invention, an anti-sticking and heat-preserving stove is provided, comprising a base portion and a stove body portion. The base portion is fitted into an opening in a tabletop, and the stove body portion is placed above the base portion. The base portion is used to hold fuel, and the stove body portion is used to heat food. The stove body portion further comprises a heat-conducting portion, which is fixedly disposed inside the stove body portion. The heat-conducting portion includes a heat-conducting plate, the upper and lower surfaces of which do not contact the stove body portion. The heat-conducting plate is used to absorb the heat released by fuel combustion and heat the stove body portion in the form of thermal radiation.

[0006] Furthermore, the bottom support includes a furnace support and a fuel support plate. The furnace support is a cylindrical shape with an opening at the top, and the fuel support plate is fixedly disposed on the bottom surface of the furnace support.

[0007] Furthermore, the furnace body includes a furnace surface and a furnace body, with the furnace surface fixedly disposed on the top of the furnace body.

[0008] Furthermore, the furnace body is a hollow columnar body with an open top and a through hole at the bottom facing the fuel tray to provide a channel for heat circulation.

[0009] Furthermore, the heat-conducting plate is located on the inner side of the top of the furnace body, and the heat-conducting plate is fixedly installed at the bottom of the furnace surface, forming a gap with the bottom of the furnace surface.

[0010] Furthermore, the heat-conducting part also includes a heating assembly and a support assembly. The heating assembly includes several spheres, several heating wires and several holes, and the support assembly includes edge strips and several support rods.

[0011] Furthermore, all the holes are provided through the heat-conducting plate, and all the spheres are located above the holes and are fixedly connected to the heat-conducting plate.

[0012] Furthermore, the heating wires are all fixedly mounted on the upper surface of the heat-conducting plate, the edge strips are fixedly mounted on the outer ring of the heat-conducting plate, and the support rods are all fixedly mounted radially on the lower surface of the heat-conducting plate, with the ends of the support rods being fixedly connected to the edge strips.

[0013] Compared with the prior art, this utility model has the following beneficial effects: A 5mm gap is left between the top surface of the heat-conducting plate and the bottom surface of the stove to hold air, preventing the heat-conducting plate from directly contacting the stove surface and avoiding the food from burning; the heat-conducting plate raises the temperature of the ball and heating wire through heat exchange, and the heat-conducting plate, ball and heating wire together heat the air between the heat-conducting plate and the stove surface, accelerating the heating speed. The heated air then exchanges heat with the stove surface, raising the temperature of the stove surface and keeping the food warm; the edge strip and support rod enhance the overall stability of the heat-conducting plate and prevent the support rod from deforming after being heated, contacting the stove surface, and directly heating the stove surface, causing uneven heating and resulting in the food burning.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figures 1 to 5 This embodiment provides an anti-sticking and heat-preserving stove, including a base and a stove body. The base is inserted into an opening in the tabletop, and the stove body is placed above the base. The base is used to hold fuel, and the stove body is used to heat the food. It also includes a heat-conducting part 2, which is fixed inside the stove body. The heat-conducting part 2 includes a heat-conducting plate 21. The upper and lower surfaces of the heat-conducting plate 21 do not contact the stove body. The heat-conducting plate 21 is used to absorb the heat released by the combustion of fuel and heat the stove body in the form of thermal radiation.

[0023] The bottom support includes a furnace support 4 and a fuel support plate 5. The furnace support 4 is a cylindrical shape with an opening at the top, and the fuel support plate 5 is fixedly installed on the bottom surface of the furnace support 4.

[0024] The furnace body includes a furnace surface 1 and a furnace body 3, with the furnace surface 1 fixedly located on the top of the furnace body 3.

[0025] The furnace body 3 is a hollow column with an open top and a through hole at the bottom facing the fuel tray 5 to provide a channel for heat circulation.

[0026] The heat-conducting plate 21 is located on the inner side of the top of the furnace body 3 and is fixedly installed at the bottom of the furnace surface 1. In this embodiment, the heat-conducting plate 21 is preferably fixed to the bottom of the furnace surface 1 by welding, and a gap is formed between the heat-conducting plate 21 and the bottom of the furnace surface 1, preferably 5mm. The 5mm air cavity separates the heat-conducting plate 21 from the furnace surface 1, which can prevent the heat-conducting plate 21 from contacting the furnace surface 1 and causing uneven heating of the furnace surface 1, and can also accelerate the heating speed of the furnace surface 1.

[0027] The heat-conducting part 2 also includes a heating group and a support group. The heating group includes several spheres 22, several heating wires 23 and several holes 26. The support group includes edge strips 24 and several support rods 25.

[0028] All holes 26 are provided through the heat-conducting plate 21, and all spheres 22 are located above the holes 26 and are fixedly connected to the heat-conducting plate 21. The height of the spheres 22 is less than 4mm to prevent them from expanding due to heat and contacting the oven surface 1, directly heating the oven surface 1, causing uneven heating, and resulting in the food being burnt. The spheres 22 increase the contact area between the heat-conducting plate 21 and the air cavity, accelerating the temperature rise rate of the air cavity.

[0029] Heating wires 23 are all fixedly installed on the upper surface of the heat-conducting plate 21, side strips 24 are fixedly installed on the outer ring of the heat-conducting plate 21, and support rods 25 are all fixedly installed radially on the lower surface of the heat-conducting plate 21. The ends of the support rods 25 are all fixedly connected to the side strips 24. The side strips 24 and support rods 25 enhance the overall stability of the heat-conducting plate 21 and prevent the support rods 25 from deforming after being heated, contacting the furnace surface 1, and directly heating the furnace surface 1, causing uneven heating and resulting in the food being burnt.

[0030] The heating wire 23 is less than 4.5mm high to prevent it from expanding due to heat and coming into contact with the furnace surface 1, which would directly heat the furnace surface 1 and cause uneven heating, resulting in the food being burnt.

[0031] The heat-conducting part 2 is fixed to the center of the bottom of the stove surface 1 by welding. After welding, a 5mm gap is left between the top surface of the heat-conducting plate 21 and the bottom surface of the stove surface 1 to hold air and prevent the heat-conducting plate 21 from directly contacting the stove surface 1, which would cause uneven heating of the stove surface 1 and burn the food. After the heat-conducting part 2 is welded to the stove surface 1, the two are then welded to the top of the stove body 3. The three are then welded together to form the stove.

[0032] After embedding the stove tray 4 into the hole on the tabletop, add fuel to the fuel tray 5 inside the stove tray 4 and ignite it. Then place the stove on the stove tray 4, so that the bottom of the stove body 3 is stuck in the cavity of the stove tray 4, with the opening at the bottom of the stove body 3 facing the fuel tray 5. This allows the heat generated by the fuel combustion to rise from the opening at the bottom of the stove body 3, heating the heat-conducting plate 21. After the temperature of the heat-conducting plate 21 rises, the temperature of the sphere 22 and the heating wire 23 increases through heat exchange. The heat-conducting plate 21, the sphere 22, and the heating wire 23 together heat the air between the heat-conducting plate 21 and the stove surface 1, accelerating the heating speed. The heated air then exchanges heat with the stove surface 1, raising the temperature of the stove surface 1 and keeping the food on it warm. The hot air inside the stove body 3 enters the hole 26 to heat the sphere 22, increasing the heating speed of the sphere 22, thereby further accelerating the temperature rise of the stove surface 1. After the stove is placed, place the food on the stove surface 1 to keep it warm and prevent it from getting cold and affecting its taste.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
