Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to an underwater heater apparatus which immerses in water to maintain and adjust water temperature to a set temperature.

In general, an underwater heater is used to keep the temperature of the aquarium water contained in the water tank or the temperature of the oil (cutting oil, hydraulic oil, etc.) constant at the factory for industrial use. Especially, in case of the water tank, The water temperature must be kept constant, and since it is virtually impossible to keep the water temperature constant, an underwater heater is provided to keep the water in the water tank at a set range.

A general structure of the above-mentioned underwater heater will be briefly described, including a heat generating tube for generating heat and a control unit for controlling the operation of the heat generating tube. The shape of the heat generating tube is not limited to the required heat generating conditions, But it is wound in the form of a coil having a substantially constant diameter and is formed within a length range that can be installed in the water tank and is connected to the control unit and a sensor rod capable of sensing the temperature of the water or the heat pipe is installed in the vicinity of the heating tube .

However, the conventional immersion heater has a risk of overheating and high temperature due to continuous operation regardless of the temperature when the electric power is applied. Particularly, a controller for controlling the water temperature to a specific temperature, that is, a temperature controller, There was a problem of inconvenience and inconvenience.

In order to solve such a problem, Korean Utility Model Registration Utility Model No. 20-0354337 entitled " Heater for a living fish aquarium " (prior art document 1) has a power cord connected to a heater for controlling power application to a heater rod, A built-in heater rod and a sensor rod for detecting the water temperature are respectively installed to integrate the controller, the heater rod, and the sensor rod so that the installation, use, and storage can be more easily performed.

Although the technology of the prior art 1 described above is intended to improve convenience of use by integrating the controller, the heater rod, and the sensor rod as a single unit, it is possible to improve the usability of the controller. However, And it is inconvenient to change the setting value of the water temperature by removing the power supply to the water surface with the power off. In addition, there is a risk of fire accidents when operated in a waterless water tank, and there is a disadvantage in that a time difference occurs in measuring the water temperature value depending on the structure in which the sensor for sensing the water temperature is installed away from the heater rod.
