Description

[0001] Industrial warm water heater structure for safety accident prevention [

The present invention relates to a hot water heater for warming hot water stored in a water tank to a portable water heater in a building construction site, a factory, a farmhouse, a military unit, etc., When the water in the water tank is above a certain temperature, the power of the heating unit is cut off by using a temperature sensor which can prevent fire and user's burn caused by contact, prevent damage to the water tank, and detect the temperature of the water stored in the water tank And a temperature sensor is provided in the inside of the inner tube to notify the user of the abnormality through a lamp and a buzzer. Therefore, a separate temperature sensor bar is not required and a temperature sensor provided inside the inner tube is separately provided A ground bracket is included to simplify the design and prevent fire and damage. The present invention relates to an industrial hot water heater structure for preventing a safety accident.

In general, a hot water heater widely used for industrial purposes is provided with a control unit having an on-off switch and a temperature control unit at an upper portion thereof, and a plurality of heater rods having a pipe structure having a heat- And at the lower end thereof, a plurality of heater rods are drawn so as to form a heat generating portion which is shaped like a pig tail is dried, and a sensor bar for temperature sensing is provided between the heater rods.

The hot water heater having the above structure is used in places where there is no boiler facility or hot water can not be used, for example, in a construction site, a factory, a farmhouse, a military unit, etc. Most of the hot water heaters are portable It is used when warming the water contained in the water tank with hot water.

When the power cord is inserted and the electricity is supplied while the control unit is properly installed on the inner wall of the water tank containing the water, the heating coil is heated and the water heated in the water tank is heated to a predetermined temperature, So that it can be used.

In the case of the sensor bar for temperature sensing, the temperature is automatically shut off when the water in the water bath is above a predetermined temperature to block the heat generation, or water in the water bath However, in the case of the conventional technology, the heater rod itself is formed into a rod as a term, and a temperature sensor or the like There is a problem in manufacturing because it can only function as a heater rod simply because it can not provide the facility and there are many problems in the grounding due to the above problems. In particular, since the top of the heater rod is overheated, There was a problem that can not be done.
