Abstract

The utility model discloses a temperature control heating rod of an electric heater, which is composed of the heating rod and a temperature controller. The temperature controller includes a controller, a control switch, a relay and a temperature sensing unit which are assembled on a circuit board and arranged in a box body; a keystroke, a digital display and an indicator lamp are arranged on a panel of the box body; by touching and pressing the keystroke, the control switch can select the corresponding control function by the controller, so as to pull in or cut off the relay, thereby controlling the heating of a heating body; meanwhile, the displaying can be carried out by the digital display or the indicator lamp. The temperature controller of the temperature control heating rod is used on the electric heater; as the intelligent automatic control function is adopted and a good operation display interface is arranged, the utilization of people is fairly convenient; temperature control heating rod can lead the electric heater to reach high heating power, and has the heating effect of a water-warming type heater; compared with the traditional water-warming type heating, the temperature control heating rod can save 20% to 30% energy; therefore, the temperature control heating rod can be adopted as a regeneration product of the water-warming type heater, and is particularly suitable for home use in southern areas where the changing of the four seasons is not obvious; and the temperature control heating rod can be particularly used for temporal or emergency heating.

Description

A kind of electric heater temperature control heating rod

Technical field

The utility model relates to a kind of electric heater device, relates in particular to a kind of electric heater temperature control heating rod.

Background technology

Traditional heating installation is water heating type heating installation, is to adopt a kind of also heating system of the hot water cyclesystem of regular supply of concentrating, and the big efficient of its thermal losses is low, and facility corrosion easily is aging, the big cost height of maintenance difficulties, and serious to air pollution.And the family expenses electric heater generally uses the mode of heating wire or halide torch heating to heat, and the shortcoming of this electric heater is that power is little, the heat effect is low, can not replace traditional water heating type heating installation heating.Effect has the use heat pipe type electric warmer preferably at present, and its structure is made up of heat-generating pipe, heat pipe, heating muff, electrically heated rod, and heat-generating pipe is welded into the inner chamber that communicates with heat pipe, is filled with conductive fluid in the inner chamber, and electrically heated rod is installed in the heating muff; Owing to adopt in the sealing heat pipe inner chamber and fill conductive fluid, have good heat conductivity during work, the advantage that radiating rate is fast is the family expenses heating electrical equipment of a kind of economical and practical, clean environment firendly, energy-saving safe; But the heating control mode lack of wisdomization of present this electric heater, its heating temp are generally only set several fixing adjustment gears, are subjected to certain restriction, use inconvenience, also are unfavorable for energy-conservation.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides a kind of electrically heated rod that is used for the electric heater device, has intelligentized control function, and the user can set the control mode of heating as required.

The utility model is achieved in that a kind of electric heater temperature control heating rod, is made up of heating rod and temperature controller, and heater is installed in the heating rod; Described temperature controller comprises controller, gauge tap, relay and temperature-sensitive unit, and is assembled on the circuit board, and is installed in the box body; The panel of described box body is provided with button, nixie display and indicator lamp, pressing button can make gauge tap select the control corresponding function by controller, so that relay adhesive or disconnection and control heater heating can be passed through nixie display or the corresponding demonstration of indicator lamp simultaneously; Described temperature-sensitive unit includes by being electrically connected and the external temperature-sensing element of outlet box.

As further improvement of the utility model, an end of described box body and heating rod is spirally connected or connects and fixes.

Described temperature-sensing element is fixedlyed connected with an end of a spring leaf, and the other end of spring leaf and box body fixedly mount, and by the elastic force of spring leaf the outer surface of temperature-sensing element and heating rod is close to.

Temperature controller of the present utility model, can control the heater work of power between 200W～1000W, the temperature parameter of temperature-sensing element can be proofreaied and correct by the PLC parameter is set, and is controlled at 15 ℃～65 ℃ scopes by the heating temp that the PLC parameter can make heater is set; Also can set intelligent control function such as automatic heating, heating at night, antifreeze heating, timing, satisfy the user to large extent and under the varying environment condition, use.

The use of temperature controller of the present utility model on electric heater is installed in heating rod in the heat-generating pipe of electric heater, and temperature-sensing element is close to the heat-generating pipe outer surface of electric heater by the elastic force effect of spring leaf; Owing to adopt intelligentized automatic control function, be provided with good operation display interface again, thereby made things convenient for people's use widely; Can make electric heater reach bigger heating power, heating effect with water heating type heating installation, and reach 20%～30% than traditional water heating type heating energy, can be as the regeneration product of water heating type heating installation, being specially adapted to the four seasons changes unconspicuous southern area household and uses, use when especially can be used as provisional or emergent heating.
