Technical Field

[0001] This utility model relates to the field of food insulation equipment, and more specifically, it relates to a safety insulation device based on a double-layer heat insulation cover. Background Technology

[0002] In the existing food insulation equipment field, traditional insulation devices generally suffer from the following technical defects: To achieve the heat insulation effect, most equipment has a large amount of fiberglass blankets built in. Fiberglass is easy to fall off during installation or maintenance. If the installers or users inhale it, it can cause respiratory damage and pose a serious health and safety hazard. The insulation structure design is simple, mostly with a single layer of insulation. Heat can easily be transferred to the outside through the shell, causing the surface temperature of the shell to often reach above 60°C, which can easily cause burns to people who accidentally touch it. Traditional insulation layers have poor heat insulation efficiency and weak heat reflection and blocking capabilities. The heat generated by the heating element is easily lost, requiring continuous high-power operation to maintain the insulation effect, resulting in high energy consumption.

[0003] In view of the shortcomings of the existing technology, there is an urgent need for a food warming device that combines safety and high-efficiency heat preservation performance to solve the problems of health hazards, burn risks and high energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a safe and reliable heat preservation device based on a double-layer heat insulation cover, achieving the goals of safety, reliability, and high heat preservation efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a safety heat preservation device based on a double-layer heat insulation cover, comprising: a shell, a first-layer heat insulation cover, a second-layer heat insulation cover, and a heating tube; The shell is a cavity structure.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] like Figure 1-3 As shown, this utility model provides a safety heat preservation device based on a double-layer heat insulation cover, including: a shell 10, a first-layer heat insulation cover 11, namely a bright stainless steel heat insulation cover, a second-layer heat insulation cover 12, and a heating tube 14. The housing 10 has a cavity structure, and a functional opening is provided at the bottom of the housing 10, through which heat can radiate to the object to be insulated below. A heat insulation cover mounting bracket 16 is provided in the cavity of the housing 10 at the position corresponding to the functional opening. The first heat insulation cover 11 is installed at the lower part of the heat insulation cover mounting bracket 16, that is, on the side close to the functional opening. The second heat insulation cover 12 is installed at the upper part of the heat insulation cover mounting bracket 16. Both the first heat insulation cover 11 and the second heat insulation cover 12 are covers with a groove at the bottom. They are both pentagonal with a central bend. This shape can effectively refract heat and reduce the heat diffusion to the outside of the housing 10.

[0020] Regarding the heat insulation cover mounting bracket 16, its structure is an inverted L-shaped frame. The bottom of the vertical part of the frame is fixedly connected to the shell. Through holes are provided on the horizontal part of the frame. Correspondingly, through holes are provided on the corresponding parts of the first-layer heat insulation cover 11, the second-layer heat insulation cover 12 and the shell 10. A long screw can be screwed into the bottom of the shell and passed through all the through holes in sequence. The head of the long screw is fixed by a nut, which can realize the installation and fixing of the first-layer heat insulation cover 11 and the second-layer heat insulation cover 12.

[0021] There is a 1cm air gap between the first layer of heat insulation cover 11 and the second layer of heat insulation cover 12. Air itself is a poor conductor of heat. This 1cm static air layer constitutes the first heat insulation barrier, which greatly hinders the heat transferred by pure thermal conduction.

[0022] A heat-insulating silicone strip 13 is provided at the edge between the first heat insulation cover 11, the second heat insulation cover 12 and the heat insulation cover fixing frame 16. The heat-insulating silicone strip 13 has the function of blocking the residual heat reflected by the first heat insulation cover 11 and the second heat insulation cover 12.

[0023] The heating tube 14 is installed on the bottom surface of the first-layer heat insulation cover 11, and the housing 10 is provided with a scalding-proof partition net 15 at the functional opening. The scalding-proof partition net 15 is installed on the top of the bottom plate of the housing 10. The scalding-proof partition net 15 and the first-layer heat insulation cover 11 form a receiving cavity in the heating tank. The heating tube 14 is placed in the receiving cavity. At the same time, the scalding-proof partition net 15 and the lower part of the housing 10 are not on the same plane, which can prevent personnel from accidentally touching and getting burned.

[0024] A windshield 17 is provided on the outer side of the front panel of the housing 10. The housing 10 and the windshield 17 are connected by a glass fixing bracket 18 with a 40° angle. The bottom of the windshield 17 is lower than the bottom of the housing 10. The front panel of the housing 10 and the top of the windshield 17 form a separation angle caused by the angle of the glass fixing bracket 18. The windshield 17 is provided with an anti-scalding mark 20. At the same time, a cover glass 19 can be provided on the top of the housing 10. Both the windshield 17 and the cover glass 19 can prevent people from being burned by the temperature of the heating tube 14 when touching the housing 10. The heating tube 14, the first-layer heat insulation cover 11, the second-layer heat insulation cover 12 and the heat insulation cover fixing frame 16 are all placed inside the cavity of the housing 10, forming an integrated structure of the safety heat preservation device, which is convenient for equipment movement and installation and use in different occasions, and can be matched with different types of food heat preservation equipment.

[0025] The advantages of this utility model are: It has a safety protection effect: it eliminates the need for a large number of built-in fiberglass blankets in traditional equipment, avoiding the risk of injury to installers and users from inhaling fiberglass; the anti-scalding partition net, the front windshield 17, the cover glass 19 and the anti-scalding sign 20 form a dual protection of "physical isolation + warning reminder", preventing direct contact between personnel and high-temperature components; It has a high heat preservation effect: the first layer of bright stainless steel heat insulation cover has the characteristics of high reflectivity and low absorption rate. Combined with the five-sided bending shape, it can reflect heat to the heat preservation area. The second layer of heat insulation cover 12 and heat insulation silicone strip 13 further block the leakage of heat, reduce heat loss, and improve heat preservation efficiency. Flexible adaptability: The integrated structural design allows the device to be adapted to different sizes and types of food insulation containers through the interface, making it suitable for various scenarios such as commercial, household, and mobile use, and easy to install and disassemble.
