Abstract
The utility model relates to a safe type electric heating apparatus that can automatically switch off when people are out. The heating apparatus is combined with and composed of a base plate, a bracket, a heat generator, a temperature adjustor and an electronic switch. The base plate is provided with four springs and a foot plate that can move vertically. The bottom of the foot plate is provided with four pushbutton switches. The pushbutton switches and a control circuit are connected together to form the electronic switch, and also control the switch on and switch off of the heat generator. When in need of heating, people places the feet on the foot plate of the heating apparatus, the pressure of the feet to the foot plate connects the power supply of the control circuit and then the control circuit begins to work with the electricity. An electric relay is connected to connect the power supply circuit of the heat generator and the heat generator start to work. When people leave, the pressure of the feet to the foot plate disappears and the electric relay is released to cut off the power supply circuit of the heat generator, realizing the target of power off when people leave.
Description
Affiliated technical field
The utility model be a kind of be the heating installation of the energy with the electricity, be to ensure that the people is from the disconnected safety electric warmer of electricity.
Background technology
At present, the various space heater on the market mainly are by base, support, heater, thermosistor, compositions such as manual power switch.Often leave and forget power cutoff because of certain reason.The people has left, and electric furnace is also in work.Electricity wasting not only, even lead to fire.
Summary of the invention
Can not accomplish the people from the disconnected shortcoming of electricity in order to overcome existing space heater, the utility model provides a kind of people from the electricity warmer that cuts off the power supply.This space heater not only has the function of existing warmer, and after the more important thing is that the people leaves, warmer can auto power off.
The technical scheme that the utility model technical solution problem is adopted is: the utility model is by base, support, and heater, thermosistor, electronic switch is formed by combining, and a spring and a press button respectively is housed around it is characterized in that on the base plate.Posting heater below the spring sustain pedal, pedal, fixedlys connected with base plate in the pillar lower end, and pedal is passed in the upper end.Four press buttones all have two groups, and are in parallel with one group of normally opened contact of relay again after one group of parallel connection, and series connection inserts in the power circuit of control circuit then; In the biasing circuit of the triode of another group back in parallel series connection access control circuit.Spring, press button and control circuit are formed electronic switch, the through and off of control heater power supply circuits.Be provided with the delay circuit of forming by resistance and capacitor in the control circuit, when four press buttones all disconnect, the heater setting-up time of still can working.
When the people warms oneself, to ride on the pedal of warmer, pin makes press button closure under the pedal to the pressure of pedal, and the power connection of control circuit, control circuit gets electric work, relay adhesive and connect the power supply circuits of heater, heater is started working.
When the people left, the press button under the pedal disconnected, but because of control circuit is provided with delay function, relay is adhesive still, and through a setting-up time, relay discharges, and the power supply circuits of heater are disconnected, and reached the people from the disconnected purpose of electricity.
The beneficial effects of the utility model are: when effectively the guarantor left warmer, warmer can auto power off.Both energy savings in the time of preventing that the people from leaving again, was forgotten the generation of the fire incident of cutting off the electricity supply and causing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is a understructure schematic diagram of the present utility model.
Among Fig. 1, S1, S2. press button, K. relay, RL. heater
Among Fig. 2,1,2. spring, 3. heater, 4. pedal, 5,6. press button, 7. base plate, 8. pillar,
The specific embodiment
As Fig. 2, a spring (1), (2) and a press button (5), (6) around going up, base plate (7) respectively are housed, spring sustain pedal (4), post heater (3) below the pedal, fixedly connected with base plate (7) in pillar (8) lower end, pedal (4) is passed in the upper end, four press buttones (5), (6) all have two groups, series connection inserts in the power circuit of control circuit as the S1 among Fig. 1 after one group of parallel connection, and the back in parallel series connection of another group inserts in the biasing circuit of triode Q1 of control circuit as the S2 among Fig. 1.
When foot-operated upper footboard (4), pedal (4) moves down along pillar, make press button (5), (6) (be the S1 among Fig. 1, S2) closure, control circuit gets electric work, constant voltage dc source is to capacitor C charging, the voltage at C two ends reaches supply voltage value rapidly.Simultaneously, power supply for the multiple tube that Q1, Q2 form provides the base stage bias current, makes the multiple tube saturation conduction through resistance R, the relay K adhesive, and its contact K1-1, k1-2 closure, k1-2 connects the heater power supply circuits, makes heater work; K1-1 provides AC power with S1 for control circuit.
When pin leaves pedal (4), pedal (4) moves on the pillar of the effect lower edge of spring (1), (2), press button (5), (6) (being S1, the S2 among Fig. 1) automatic disconnection simultaneously, capacitor C is through resistance R, the multiple tube discharge, make multiple tube keep conducting state, to keep the operate as normal of heater; Along with the delay of time, the undertension on the capacitor C is to keep the conducting of multiple tube, and relay K just discharges, and the power supply circuits of heater just are cut off, thereby has reached the people from the disconnected purpose of electricity.
Claims (3)
1. a space heater is by base, support, heater, thermosistor, the electronic switch combination forms, and it is characterized in that: a spring and a press button, spring sustain pedal respectively are housed around on the base plate, posting heater below the pedal, fixedlys connected with base plate in the pillar lower end, and pedal is passed in the upper end.
2. space heater according to claim 1, it is characterized in that: four press buttones all have two groups, after one group of parallel connection, in parallel with one group of normally opened contact of relay again, then in the power circuit of series connection access control circuit, in the biasing circuit of the multiple tube of another group back in parallel series connection access control circuit.
3. space heater according to claim 1 is characterized in that: be provided with the delay circuit of forming by resistance and capacitor in the control circuit, and when four press buttones all disconnect, the heater setting-up time of still can working.
