Description

Industrial warm water heater

The present invention relates to an industrial hot water heater, and more particularly, by applying a protective device for safety to the hot water heater, which is sold and used at a low price, to prevent the heat generating part directly coming into contact with the inside of the water tank to prevent the burn of the user. The present invention relates to an industrial hot water heater to prevent damage and fire of a water tank and to easily hang a hot water heater from a water tank.

In general, hot water heaters (also called 'pigtail heaters'), which are widely used for industrial purposes, are portable from places where no boiler facilities are available or where hot water cannot be used (construction works, factories, farmhouses, military units, etc.). The hot water heater is carried to the site, and electricity is supplied to warm the water.

The heating temperature of the water using the hot water heater is used to heat the water to approximately 70 ~ 80 ℃, the power use is divided into 3kW or 5kW, and is widely used in that it is convenient to move.

The hot water heater widely used in the industry as described above is divided into low-cost and high-grade type, the high-grade type is a control body equipped with a temperature control knob, a display lamp, a power switch, a hook, and drawn out in two strands from the control body, respectively. The heater rod having a heating rod formed to be connected to one another in the form of mutual pig tail, and a sensor rod which is drawn out from the control body so that the end is installed close to the heating portion to sense the temperature of the water is soaked in the tank The temperature control is automatically adjusted according to the operating temperature so that it can be used.

The low-cost industrial hot water heater 10 has a hook 12 is provided from the body 11, as shown in the accompanying Figure 1, and drawn out in two strands from the lower side of the body, respectively, the end portion is mutually pig tail shape It simply consists of a heater rod 14 having a heat generating portion 14a formed to be rolled into one.

For reference, the heating element 14a of the heater rod 14 is guided by a heating wire, that is, a nichrome wire in the form of a coil, and at the same time, while the surroundings hold the heating wire stably, while maintaining the shape, the stone powder is evenly generated. Is charged. The heating wire is connected to the electric wire passing through the heater rod from the body.

Existing hot water heater 10 having the configuration as described above is a heating wire by plugging the power cord into the outlet in the state in which the hook (12) provided on the body 11 to the water tank (1) that can hold water to supply electricity. Heating the water contained in the water tank 1 to a predetermined temperature makes it possible to use hot water.

Substantial use of the hot water heater to immerse the heater rod in the water tank as described above is as shown in Figures 2 and 3 attached.

Attached Figure 2 is to be used to hang the hooks integrally provided in the rear of the body to the upper end of the tank, to use the hot water heater to fit the depth of the tank can accommodate the heater rod enough.

3 is a view showing an example in which the hot water heater is inclined to be used in a water tank having a height lower than the length of the heater rod of the hot water heater, and the heating part of the heater rod is used in contact with the bottom surface of the water tank. to be. At this time, the hot water heater is in a state that can not be hooked to the tank using a hook.

Normally, the tank may use an aluminum tank, but since most of the tanks made of rubber materials are usually used in the field, the heating part touching the bottom surface of the tank may damage the tank as described above. have.

In other words, the low-cost hot water heater as described above is not equipped with a device that can automatically control the temperature control and temperature compared to the high-end type, when the water dries in the tank often happens to melt or burn the water tank accidental fire accident There is a problem that requires special attention in use because it causes the.

In addition, there is a problem that a safety accident that can cause burns in the process of handling the hot water heater in the heat state as the heat generating portion that is the highest heat generation in the heater rod is exposed as it is.

The present invention has been invented in view of the conventional problems as described above, by applying a protective device for safety to hot water heaters sold and used at low cost to prevent the heat generating portion to directly contact the inside of the water tank of the user It is an object of the present invention to provide an industrial hot water heater that can be used to easily hang the hot water heater from the water tank while preventing the damage and fire of the water tank with burn prevention.

According to the present invention for achieving the above object, the hook is provided on the body and supported by the hook hanging on the upper edge of the tank, and the heater rod having a heating portion formed to be connected to each other by the end portion is rolled out in the form of a mutual pig tail, respectively In the industrial hot water heater consisting of,

A protective device for enclosing the heating portion to prevent contact with the heating portion from the water tank, a connecting portion attached to one side of the protective device, one end is connected from the connecting portion and the other end is fixed to the body side to support the protective rod is installed It features.

In addition, the protective device of the present invention is characterized in that the upper portion is formed in a container shape having a side and a bottom.

In addition, the protective device of the present invention is characterized in that formed in the shape of a protective net.

In addition, one side of the hook through the support rod of the present invention is characterized in that the hook is movable up or down in the longitudinal direction of the support rod according to the height of the tank.

In addition, the support rod of the present invention is provided with a plurality, and one side of the hook is passed through the support rod is characterized in that the hook in the longitudinal direction of the support rod according to the height of the tank is installed to move up, down.

In addition, the hook of the present invention is characterized in that the rotatably installed in the connecting shaft on the upper portion of the body.

The hot water heater according to the present invention is a protective device surrounding the heat generating part of the heater rod, even if it is in a state vertically or inclined over the inside of the water tank to prevent direct contact with the water tank to prevent damage to the water tank, the real user directly handling the hot water heater Since the risk of touching burn can be eliminated, and the hook applied to move up and down from the supporting rod connected to the protective device can be used by standing the hot water heater vertically from the tank by adjusting the position of the hook according to the height of the tank to be used. Low temperature industrial hot water heater without temperature sensor device or high quality hot water heater with temperature sensor device can be easily applied and used effectively.
