Heater for camping house

Abstract

The invention discloses a heater for a camping house. The heater comprises a shell, heating wires, binding posts and a plurality of metal pipes, wherein the metal pipes are arranged inside the shell in a staggered mode. A plurality of through holes are formed in the shell, the heating wires are installed inside the metal pipes, the two ends of each metal pipe are provided with plugs, and the binding posts penetrate through the plugs to be connected with the heating wires and are connected with an external power source. The heater further comprises an insulator and an overheat protective device, the insulator is arranged between the heating wires and the metal pipes, and the overheat protective device is installed in the through holes inside the shell and is connected with the binding posts. When the temperature inside the shell rises to the maximum, the overheat protective device in the through holes cuts off the external power source until the temperature is reduced to the normal level, the external power source continues to supply power, the heating wires continue to emit heat, the phenomenon that the heating wires are burned out due to high temperature is avoided, meanwhile, the working stability of the heater is improved, and the long service life of the heater is guaranteed.

Description

technical field [0001] The invention relates to a heater, in particular to a heater which can be used in a camping house. Background technique [0002] The camping room is a necessary common equipment for oil exploration and development sites, and it is a place for workers to live and rest and store tools and other equipment. Camping houses can be divided into two categories according to different functions, namely on-site engineering houses and living camping houses, with a total of more than 30 varieties. However, because it does not belong to the main equipment directly used for exploration, development and production, it mainly serves as an auxiliary service, so it has not received much attention. Most of the camping houses used in many oil exploration and development sites have relatively simple structures and rough craftsmanship. , the function is not strong. [0003] Especially in cold weather, oil extraction equipment is prone to lower working efficiency or even da...

AI Technical Summary

Problems solved by technology

[0003] Especially in cold weather, oil extraction equipment is easy to work in a low temperature environment and even be damaged. Therefore, the insulation measures of the equipment in the camping house must be perfect to ensure the stability of the indoor temperature.

At present, separate electric heating wire heaters are generally used in the market. After a long time of use, the electric heating wire is easily oxidized and damaged in a high temperature environment, resulting in heating interruption
