Description

The electric fire-box of intelligent safety

Technical field:

The utility model relates to a kind of heating installation, relates in particular to the electric fire-box of heating usefulness.

Background technology:

At present, widely used electric fire-box has only temperature control and temperature display function mostly, and does not have power-off protection function; It is short not only to waste electric energy, service life, but also has bigger potential safety hazard, mainly shows following power face:

1) forgets powered-down because of a variety of causes and cause waste of electric energy;

2) temperature detect switch (TDS) is in load-carrying duty for a long time, and main contacts damages easily;

3) heating is in the hot operation state for a long time and damages easily;

4) forget to close outage source initiation fire easily because of a variety of causes;

5) cause short circuit initiation fire or electric shock accidents easily because of a variety of causes.

Summary of the invention:

At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of electric fire-box of intelligent safety with prompt functions and automatic power-off protection function.

To achieve these goals, the utility model by the following technical solutions: it comprises casing, be arranged on heating and temperature detect switch (TDS) in this casing, be arranged on the controller on the casing; Controller is by intelligent control module, and the detections of radar module that is electrically connected with this energy control module, temperature control modules, warning and state display module, power output adjustment module and power module constitute respectively; Heating is electrically connected with the power output adjustment module, and temperature detect switch (TDS) is electrically connected with intelligent control module.

On controller, be provided with the reset switch that is electrically connected with intelligent control module; On controller, be provided with the protective tube that is electrically connected with power module; On controller, be provided with the indicator lamp that is electrically connected with intelligent control module.

Compared with the prior art, the utility model is owing to adopted technique scheme, therefore the microwave that can reflect according to Doppler radar effectively perception whether people's activity is arranged near electric fire-box, and make the judgement that switches on or off power supply exactly, thereby can realize power-off protection by intelligent control module; Not only improve the security of electricity consumption, also reached the purpose that prolongs heating service life and using electricity wisely simultaneously.In addition, owing on controller, be provided with the reset switch that is electrically connected with intelligent control module, therefore circuit just can be reworked after must pressing reset switch after the outage, even if otherwise that temperature regulation switch is in on-state is also invalid, instrument has not further improved the security and the reliability of system, but also has prolonged the physical life of temperature regulation switch.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

As shown in Figure 1: some pedals 6 are arranged in the casing 1 by support 3, and heating 4 is arranged on the below of pedal 6, are provided with temperature detect switch (TDS) 5 near close heating 4 below the pedal 6; The outer wall of casing 1 is provided with controller 2, and this controller is provided with the temperature regulation switch 8 that is used to control temperature.Controller 2 is made of intelligent control module 15, detections of radar module 11, temperature control modules 12, warning and state display module 13, power output adjustment module 14 and power module 16, and temperature detect switch (TDS) 5, detections of radar module 11, temperature control modules 12, warning and state display module 13, power output adjustment module 14 and power module 16 are electrically connected with intelligent control module 15 respectively; Heating 4 is electrically connected with power output adjustment module 14.

Advantages such as in technique scheme, power output adjustment module 14 adopts traditional controllable silicon regulative mode, has circuit and stablizes, and is durable in use; Power module 16 is adopted as the 220/9V rectifier transformer that whole system provides electricity consumption; Detections of radar module 11 is electrically connected with inductor by J1, by this inductor signal is transferred to intelligent control module 15 by J1 again.

For security and the reliability that has further improved system,, on controller 2, be provided with the reset switch 7 that is electrically connected with intelligent control module 15 simultaneously also in order to have prolonged the physical life of temperature regulation switch 8; For fear of because of short circuit initiation fire or electric shock accidents, on controller 2, be provided with the protective tube 10 that is electrically connected with power module 16.In addition, for easy to use, on controller 2, be provided with the indicator lamp 9 that is electrically connected with intelligent control module 15.

Operation principle: after controller 2 is connected power supplys, transformer with the alternating current step-down of 220V, rectifying and wave-filtering after to each module for power supply; This moment, indicator lamp 9 was luminous, and indication circuit is working properly.Rotational temperature by-pass cock 8 can change the power output of power output adjustment module 14, thus the heating temp of adjustable economize on electricity thermal element 4; When the temperature inside the box was too high, temperature detect switch (TDS) 5 can be cut off the electricity supply automatically, and warning simultaneously and state display module 13 are connected with power module 16 and sounded a buzzer and remind the user to reduce temperature; When the temperature inside the box was reduced to a certain degree, temperature detect switch (TDS) 5 was connected power supply, and heating 4 works on again.In use, when the people not powered-down and leave or sleeping after, because detections of radar module 11 detects the microwave that reflects less than mobile object, therefore intelligent control module 15 is not owing to receive the signal of detections of radar module 11 transmission and delay time and cut off the electricity supply automatically after a period of time, both guaranteed Electrical Safety, and played using electricity wisely again, prolonged the electrical equipment effect in service life.When being short-circuited, protective tube 10 can fuse automatically and cut off the electricity supply, thereby can avoid accident to continue to enlarge.
