As the name suggests, it uses electricity as energy and converts it into thermal energy, which is then converted by the boiler to output steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] Chinese patent with application number 202021144039.8 discloses a side-wall anti-freeze boiler, in which the outer wall of the boiler body is fixedly connected with a first insulation layer, the inner wall of the boiler body is fixedly connected with a second insulation layer, a heating plate body is arranged on the outside of the first insulation layer, and an electric push rod drives the heating plate body to move up and down to evenly heat the side wall of the boiler body, and the purpose of good anti-freeze performance of the boiler side wall is achieved through the mutual coordination of the electric push rod, fixed block, slider, connecting block, first fastening bolt, heating plate body, slide groove, guide slider, boiler body, first insulation layer and second insulation layer, which solves the problem of poor anti-freeze performance of the side wall of general boilers; however, in this patent, the heating plate body is located at the outermost side and is directly exposed to the external environment. When the side wall of the boiler body is heated by the heating plate body, part of the heat of the heating plate body will diffuse into the environment, causing heat loss and affecting the heating efficiency. Utility Model Content

[0004] The utility model aims to provide an antifreeze electric boiler to solve the problem that when a heating plate body is used to heat the side wall of a boiler body, part of the heat of the heating plate body will diffuse into the environment, causing heat loss and affecting the heating efficiency.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model discloses an antifreeze type electric boiler, comprising an electric boiler body, a protection box is arranged on the outside of the electric boiler body, hanging rings are arranged on the left and right sides of the protection box, a base is arranged on the bottom surface of the protection box, a heat preservation component is arranged on the inner side of the protection box, a plurality of threaded rods are arranged on the top surface of the base, threaded seats are arranged on the threaded rods, a connecting plate is arranged between two adjacent threaded seats, an electric heating plate is arranged on the inner side of the connecting plate, and a driving component is arranged above the threaded rods.

[0007] Furthermore, the insulation component includes a rigid foam polyurethane insulation board layer, a mineral wool layer and a sponge layer which are arranged in sequence from the outside to the inside, the outer side of the rigid foam polyurethane insulation board layer is bonded to the inner wall of the protection box, the inner side of the rigid foam polyurethane insulation board layer is bonded to the mineral wool layer, and the inner side of the mineral wool layer is bonded to the sponge layer.

[0008] Furthermore, the number of the threaded rods is set to four, and the four threaded rods are arranged at the four corners of a rectangle.

[0009] Furthermore, the driving assembly includes a motor, which is installed above the protective box through a bracket, and the output shaft of the motor is connected to one of the threaded rods. A transmission wheel is installed on the top of the threaded rod, and two adjacent transmission wheels are connected by a synchronous belt transmission.

[0010] Furthermore, a dust cover is provided on the outer side of the driving assembly, and the dust cover is connected to the top of the protection box by bolts.

[0011] Compared with the prior art, the beneficial technical effects of the utility model are:

[0012] When the electric boiler needs to be protected from freezing, the utility model is hoisted to the outside of the electric boiler body, and the electric boiler is insulated by the heat-insulating component inside the protection box. When the antifreeze protection is not needed, the utility model can be immediately removed. The utility model is simple and convenient to use and can be reused, thereby reducing the waste of materials and saving production costs. When the ambient temperature is too low and the heat-insulating component alone cannot meet the antifreeze requirement, the driving component mobilizes the threaded rod to rotate, thereby driving the connecting plate and the electric heating plate to move up and down, and heating the four sides of the electric boiler body. The electric heating plate is located in the protection box, and the heat-insulating component inside the protection box prevents heat from diffusing to the external environment, thereby improving the heat-insulating effect, and can effectively prevent the electric boiler body from being frozen and cracked, thereby improving the antifreeze performance of the electric boiler.
