[0002] High-temperature radiant heaters are widely used in hotels, schools, offices and homes due to their advantages such as being pollution-free, having a rapid temperature rise, and high heat conversion efficiency.

[0003] However, existing high-temperature radiant heaters generally have the problem of high energy consumption, especially when it is used to provide 24-hour indoor heating. The large amount of electricity consumed and the resulting expenses have become one of the difficulties in popularizing high-temperature radiant heaters.

[0004] Therefore, in view of this, we studied and improved the existing structure to propose an indoor heater with good stability. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable indoor heater, comprising a shell and a heating element, wherein the shell houses the heating element, which includes a heat storage body, a through hole, a dry-burning heating rod, and a junction box. The heat storage body is made of solid magnesium oxide material with high specific heat capacity, and two sets of heat storage bodies are arranged side by side with heat-resistant mud filling the adjacent gaps. A through hole is opened in the middle of the heat storage body, and a dry-burning heating rod is spirally arranged between adjacent heat storage bodies through the through hole. Junction boxes are provided at both ends of the "U"-shaped structure of the dry-burning heating rod, and the junction boxes are electrically connected to the mains power through a power cord.

[0007] Furthermore, the top two sides of the outer casing are provided with mounting bracket connection holes, and the bottom opening of the outer casing is bolted to a heating plate.

[0008] Furthermore, a wire-passing partition is fixed in the middle of the outer shell, and a wire-passing cavity is provided on one side of the wire-passing partition.

[0009] Furthermore, the top of the lead cavity is provided with a lead outlet hole, and the bottom opening of the lead cavity is provided with a maintenance plate.

[0010] Furthermore, the inspection plate array has heat dissipation holes, and the root of the inspection plate is rotatably connected to the wire-threading partition via a hinge.

[0011] Furthermore, a heating chamber is provided on the other side of the wire-threading partition, and the side wall of the heating chamber is provided with a heat insulation layer made of asbestos material that is resistant to high temperature and has low thermal conductivity.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In use, this utility model uses a high-temperature resistant dry-burning heating rod to generate heat. It utilizes the low-cost electricity during off-peak hours at night to complete the electrothermal conversion and store it in the heat storage body. During peak hours, the stored heat is released through radiation to achieve 24-hour indoor heating. This not only saves on heating costs, but also ensures quiet and noiseless operation because it does not require the use of fans or other components. It is stable and does not require frequent maintenance.

[0014] 2. When in use, the fixing bracket connection holes on both sides of the high-temperature radiant heater shell can be used with the mounting bracket to achieve inclined wall-mounted installation and ceiling-mounted installation. The asbestos insulation layer attached to the inner wall of the heating cavity on one side of the wiring partition is used for heat storage and directional release. The lead wire cavity on the other side of the wiring partition can be quickly inspected through the setting of the inspection plate, and heat dissipation is assisted by the heat dissipation holes. The steel powder-coated shell protects and beautifies the entire device. Attached Figure Description
