Abstract
The utility model relates to an electric control multiple protection system of a heating unit. The electric control multiple protection system of a heating unit is characterized by comprising a first relay, a second relay, a temperature-sensing element, and a control unit; the first relay and the second relay are successively connected on the power supply line of a heating unit in series; the temperature-sensing element is arranged on the heating unit and is used for detecting the temperature of the heating unit; the control unit is connected with the first relay, the second relay and the temperature-sensing element; and the control unit is used for collecting whether failure signals of the first relay and the second relay exist and collecting the temperature signals output by the temperature-sensing element, and if the failure signals of the first relay or the failure signals of the second relay or the abnormal signals of the temperature-sensing element are collected by the control unit, control signals are output to the first relay and the second relay so that the first relay and the second relay are turned off simultaneously, thereby cutting off the power supply of the heating unit. Compared with the prior art, the multiple protection system of the heating unit enables the heating unit to be effectively protected and allows the safety to be greatly improved.
Description
Technical field
The utility model relates to a kind of automatically controlled multiple-protection system of heating unit.
Background technology
Water fountain, water heater, boiling water machine etc. are given in the liquid heater, and heating unit is the parts of most critical.The protection of heating unit is also become these install most important most crucial link.
The protection of existing heating unit is relay of serial connection in the supply line of heating unit normally, and the folding of this relay is controlled through a controller, and then the power supply of control heating unit cut-offs.But when abnormal conditions such as bonding appearred in relay, the power supply of heating unit just can't break off, and will cause heating unit to be worked so always, thereby can damage liquid heating, and the danger of easy breaking out of fire is more arranged.
The utility model content
The utility model technical problem to be solved is the automatically controlled multiple-protection system that a kind of better safety performance heating unit is provided to above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the automatically controlled multiple-protection system of this heating unit; It is characterized in that: comprise first relay and second relay in the supply line that is serially connected in heating unit successively; Be arranged on the temperature-sensing element that is used to detect the heating unit temperature on the heating unit; And the control unit that links to each other with temperature-sensing element with first relay, second relay; This control unit is used to gather first relay and whether second relay has disablement signal and be used to gather the temperature signal of temperature-sensing element output; And behind the abnormal signal of the disablement signal of the disablement signal that collects first relay or second relay or temperature-sensing element; The output control signal is given first relay and second relay, is able to cut off thereby make first relay and second relay turn-off the power supply that makes said heating unit simultaneously.
Said heating unit is provided with temperature protective device, and this temperature protective device also is serially connected in the supply line of heating unit.
Said temperature protective device is a fuse-link.
As improvement, thereby the utility model comprises that also input links to each other with external civil power, output links to each other with said control unit, is used for line voltage is carried out the power module that said control unit power supply is given in pressure drop.
Said temperature-sensing element is a heat sensor.
Compared with prior art; The advantage of the utility model is: through two relays of serial connection in the supply line of heating unit; Can not work like this because of the bonding calandria that causes of individual relay always; Form by series connection is carried out conducting another can in time be protected when one of them relay goes wrong, and the probability that 2 relays damage simultaneously in the actual working state is very little; And on heating unit, be used to detect the temperature-sensing element of heating unit temperature; When heating unit was overheated, temperature-sensing element also can output signal to control unit, and control unit also can turn-off two relays like this; Heating unit is protected; The multiple-protection system of the heating unit that the utility model provides makes heating unit be effectively protected, and fail safe is greatly improved.
Description of drawings
Fig. 1 is the theory diagram of the automatically controlled multiple-protection system of heating unit among the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
The automatically controlled multiple-protection system of heating unit as shown in Figure 1; It comprises first relay 1 and second relay 2 in the supply line that is serially connected in heating unit 3 successively; Be arranged on the temperature-sensing element 4 that is used to detect the heating unit temperature on the heating unit 3; And the control unit 5 that links to each other with temperature-sensing element 4 with first relay 1, second relay 3; This control unit 5 is used to gather first relay 1 and whether second relay 2 has disablement signal and be used to gather the temperature signal of temperature-sensing element 4 outputs; And behind the abnormal signal of the disablement signal of the disablement signal that collects first relay 1 or second relay 2 or temperature-sensing element 4, the output control signal is given first relay 1 and second relay 2, is able to cut-out thereby make first relay 1 and second relay 2 turn-off the power supply that makes said heating unit 3 simultaneously.
In addition, said heating unit 3 is provided with temperature protective device 6, and this temperature protective device also is serially connected in the supply line of heating unit, and temperature protective device described in the present embodiment is 6 fuse-links.Said temperature-sensing element 4 is a heat sensor.
In addition, thus the utility model comprises also that input links to each other with external civil power, output links to each other with said control unit, is used for line voltage is carried out the power module 7 that said control unit power supply is given in pressure drop.Said control unit adopts conventional processor of single chip computer with program capability or microprocessor.
