Description
Technical field
The utility model relates to a kind of household electrical appliance, relates in particular to a kind of pedal type electric heating box (device).
Background technology
Pedal type electric heating box (device), take casing as heating carrier, and auxiliary warming covering (warm oneself by a fire by) makes the heat energy of electro-heat equipment, in casing, is stored.In the heating of the space of sealing relatively, human body comfort, the advantage of low energy, is that other warmers are incomparable.Pedal type electric heating box, is therefore liked by people also deeply, becomes the indispensable household electrical appliances of warming.At present, foot-operated heating box (device) product that mainly contains solid wood of market sale, there to be the foot-operated heating box (device) of part injection moulding.
No matter be the foot-operated heating box of solid wood or injection moulding, must add and warm oneself by a fire by inflammable warming covers such as, woollen blankets when brothers warm oneself, this buries potential safety hazard for electricity consumption heating in winter.According to fire department, add up and fire victim is investigated, the reason of foot-operated heating box breaking out of fire mainly contains: the one, and when user leaves, forget and close heating box power switch, make the electro-heat equipment persistent fever of heating box, cabinets cavity excess Temperature, ignite wooden pedal frame and warming cover, lead to fire.The 2nd, during unexpected power-off, user leaves something lost note and closes heating box power switch.After restoring electricity, the electro-heat equipment persistent fever of the heating box of not closing, cabinets cavity excess Temperature, ignite wooden pedal frame and warming cover, lead to fire.
Utility model content
For overcoming the potential safety hazard in foot-operated heating box use procedure, it is a kind of safe and practical that the utility model provides, " people is logical at electricity ", the pressure breaker device of the foot-operated heating box of " people is from power-off ".
The utility model solves the technical scheme that its technical problem adopts, a kind of pressure breaker device of foot-operated heating box, by casing (1), pedal frame (2), supporting traverse (3), power circuit, temperature regulating switch (4), electro-heat equipment (5) forms, and it is characterized in that: in the middle of the circuit of temperature regulating switch (4) and electro-heat equipment (5), and the single-pole single-throw switch (SPST) (6) of connecting and controlled by pedal frame (2).
Described pedal frame (2) is upper, and Baltimore groove (7) is installed.
Described Baltimore groove (7) is the Baltimore groove of duroplasts shaping.
Described Baltimore groove (7) below, supporting traverse (3) is upper, has back-moving spring (8).
Described single-pole single-throw switch (SPST) (6), has single-pole single-throw(SPST toggle switch, single-pole single-throw(SPST rocker type switch, single-pole single-throw(SPST press button etc.This case is preferred, for having the single-pole single-throw(SPST toggle switch of convex-edge shape.
Described single-pole single-throw switch (SPST) (6), is arranged on box inside, supporting traverse (3) top, and installation site is corresponding with the Baltimore groove (7) on pedal frame (2), and the rocking bar of single-pole single-throw switch (SPST) is in groove.
The beneficial effects of the utility model are that the utility model solves three foundations of its technical problem, according to human bady gravitational; Function according to a stationary contact of single-pole single-throw switch (SPST), a movable contact, a passage; According to spring reset function.Remove the state of forcing breaker device, the precondition that device arranges, must be that people's both feet are warmed oneself on pedal frame.Be that power switch is opened, people's both feet, not on the pedal frame of heating box, force breaker device still in closed condition, and the power channel of electro-heat equipment still cannot be opened.The both feet that only have people on the pedal frame of heating box time, are subject to human bady gravitational effect, could remove the closed condition of forcing breaker device, open the power channel of electro-heat equipment.Accomplished " people is logical at electricity ", " people is from power-off ", realizes the safety utilization of electric power of heating box.With existing " human induction switch ", " gravity sensing switch " technology comparison, the design of this pressure breaker device, simple in structure, with low cost, install simple and easy, economical and practical, safe and practical.
Accompanying drawing explanation
The pressure breaker device schematic diagram of a kind of foot-operated heating box of Fig. 1.
In figure: 1. casing.
2. pedal frame.
3. supporting traverse.
4. temperature regulating switch.
5. electro-heat equipment.
6. single-pole single-throw switch (SPST).

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, force breaker device, by the Baltimore groove (7) on pedal frame (2) and pedal frame, single-pole single-throw switch (SPST) (6), back-moving spring (8), in the middle of the temperature regulating switch (4) of heating box and the circuit of electro-heat equipment (5), forms one and independently forces normally closed power circuit system, even if open temperature regulating switch (4), power supply also cannot be by forcing breaker device to arrive electro-heat equipment (5).
While only having people's both feet on the pedal frame (2) of heating box, be subject to human bady gravitational effect, pedal frame (2) is compression reseting spring (8) downwards, Baltimore groove (7) on pedal frame (2), the rocking bar of the single-pole single-throw switch (SPST) (6) of promotion in groove is downward, open the power channel of electro-heat equipment, just can complete and remove the closed condition action of forcing breaker device.
When people's both feet leave the pedal frame (2) of heating box, gravity disappears, back-moving spring (8) resets, promote pedal frame (2) upwards, Baltimore groove (7) on pedal frame (2), the rocking bar of the single-pole single-throw switch (SPST) (6) of promotion in groove makes progress, the power channel of positive closing electro-heat equipment, the normally off of recovering to force breaker device.
Visible, a kind of pressure breaker device of foot-operated heating box, has accomplished " people is logical at electricity ", and " people is from power-off ", realizes the safety utilization of electric power of heating box.
As a utility model case study on implementation, the technical scheme of the pressure breaker device design of a kind of foot-operated heating box that the utility model provides, wherein, force the switch of breaker device, in single-pole single-throw switch (SPST), there is single-pole single-throw(SPST rocker type switch, the multiple choices such as single-pole single-throw(SPST press button, this case preferably has the single-pole single-throw(SPST toggle switch of convex-edge shape.Baltimore groove selects duroplasts to be shaped, and also other materials are shaped.In every case many variations and can not depart from the present utility model.
Although with reference to comprising that the utility model presently preferred embodiment is described the utility model, those skilled in the art will recognize that shape, formation or its combination of foregoing description also exists multiple variation and change.Therefore, Spirit Essence of the present utility model and scope should be explained widely as stated in the claim of submitting to.
