Description
The utility model relates to a kind of heating system, relates in particular to a kind of electric foot warmer.
Existing electric foot warmer has footwear formula and board-like two kinds, all gives people's pin by solid heat transfer, and it is inhomogeneous that heat transfer rate is slow, foot is heated, and purposes is single, and does not have control function automatically.
It is fast that the purpose of this utility model provides a kind of heat transfer, and foot is heated evenly, diverse in function, the intelligent multifunction electric foot warmer that can carry out automated intelligent control again according to behaviour in service.
For achieving the above object, the technical solution adopted in the utility model is: in the electric foot warmer of being made up of heater element, housing, the heater element back is equipped with a heat extraction blower fan; The outlet air surface of housing is equipped with four foldable long stents, and a side of housing is equipped with four foldable short supports in addition; Be equipped with the light emitting devices and the light-sensitive device that link to each other with intelligence control circuit on the long stent.
The utility model is compared with existing electric foot warmer, has to conduct heat soon, and foot is heated evenly, and diverse in function can be carried out the advantage of Based Intelligent Control again according to behaviour in service.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model internal structure vertical view.
Fig. 2 is the utility model internal structure side view.
Fig. 3 is the schematic diagram that the utility model keeps flat use.
Fig. 4 is the side view that the utility model is tiltedly put use.
Fig. 5 is that the utility model stands up and makees the side view cold, that warm-air drier is used.
Fig. 6 is the structural representation that the utility model long stent is folded in housing.
Fig. 7 is the utility model control circuit schematic diagram.
Can find out from Fig. 1, Fig. 2, the utility model is made up of heater element 1, housing 2 etc., heater element 1 back is equipped with a heat extraction blower fan 3, during work, heat extraction blower fan 3 is heated into warm braw by 13 suctions of air draught face through heater element 1 with cold wind and blows out from outlet air surface 4, enter the heating space, fast even warm foot.
Can find out from Fig. 3, Fig. 4, Fig. 5, the utility model is equipped with four foldable long stents 5 on the outlet air surface 4 of housing 2, on a side 6 of housing 2, be equipped with four foldable short supports 7, be equipped with the light emitting devices 8 that links to each other with control circuit on one long stent 5, be equipped with light-sensitive device 9 on another long stent 5.
As can be seen from Figure 7 in control circuit, the output of light-sensitive device 9 links to each other with the input of NAND gate 10, the control branch road of the output of NAND gate 10 and the air-heater 3 that runs in and the control branch road of heater element 1, the control of heat extraction blower fan 3 prop up output, phase inverter 11, the resistance R of route NAND gate 10
1, transistor BG
1, resistance R
3, control hangs silicon SCR
1, heat extraction blower fan 3 order links to each other and constitutes; Output, phase inverter 12, the resistance R of route NAND gate 10 propped up in the control of heater element 1
2, transistor BG
2, controllable silicon SCR
2, resistance R
4, heater element 1 order links to each other and constitutes.
As can be seen from Figure 6, long stent 5 of the present utility model can not have the folding of evagination ground in the groove 14 of housing 2.Every support in the utility model comprises that short support also all does processing like this.
Can find out from Fig. 3, Fig. 7, four long stents 5 on the utility model housing 2 are strutted that four short supports are folded in the groove 14 on the housing 2, the utility model can lie on the ground and use.To develop K
1Dial to Based Intelligent Control end a point, it is that pin enters outlet air surface 4 bottoms heating spatial dimension that the utility model just can carry out Based Intelligent Control, and machine is worked automatically, after pin leaves warmer, and the machine autostop.Control principle is:
When pin enters the heating spatial dimension of outlet air surface 4 belows, the light that luminescent device 8 sends is blocked, light-sensitive device 9 can not detect corresponding light and end, 9 outputs are that high level then is low level through NAND gate (10) output, and this low level signal is imported the control branch road of heat extraction blower fan 3 and the control branch road of heater element 1 respectively; In the control branch road of heat extraction blower fan 3, this low level signal is anti-phase by phase inverter 11 to be that high level is through resistance R
1To transistor BG
1Base stage, make BG
1Conducting, BG
1Colelctor electrode produces a current signal and triggers controllable silicon SCR
1Conducting, heat extraction blower fan 3 gets electric work; The control branch road operation principle of heater element 1 is identical with above-mentioned heat extraction blower fan 3 control branch road operation principles, heater element 1 also simultaneously electric work, complete machine is in automatic mode at this moment.
When pin leaves; the light that luminescent device 8 sends is not blocked; received by light-sensitive device 9; light-sensitive device 9 conductings; it is opposite when each corresponding device power on signal variation situation just in time enters the heating space with above-mentioned pin in the intelligence control circuit; make heater element 1 and heat extraction blower fan 3 all cut off the power supply, complete machine is in the autostop state.
Can find out from Fig. 4, Fig. 7; two short supports 7 near outlet air surface 4 on the utility model side 6 are strutted; two short supports 7 are folded in the housing groove 14 in addition; two long stents near side 6 are folded on the housing; two long stents strut in addition, and the utility model then tiltedly is put on the ground and uses, and also have according to pin whether enter the heating space; automatically the Based Intelligent Control function of opening, shutting down, its operation principle with keep flat when using identical.Tiltedly put occupation mode and compare with keeping flat, pin can deeper stretch into the heating space, and the warm braw wind direction is also more towards human body, people's pin, thereby obtains better heating effect, especially is fit to old, children and uses.
As can be seen from Figure 7, in the utility model row warm-air drier 3 the control branch road in controllable silicon SCR
1The resistance R of joining
3Adopt negative tempperature coefficient thermistor, the utility model also possesses automatic constant-temperature control function.Principle is when built-in temperature raises, thermistor R
3Resistance descends, through R
3Flow to controllable silicon SCR
1Trigger current increase SCR
1The angle of flow increase, heat extraction blower fan operating current increases, rotating speed increases, air output increases, and makes the warm braw temperature that blows out descend; On the contrary, when built-in temperature reduces, R
3Resistance increase, heat extraction blower fan speed drop is low, air output falls few, the warm braw temperature rises.
As can be seen from Figure 5, four long stents 5 of the utility model are folded in the housing, four short supports strut, and it is stood up on the ground, and the utility model then can doublely be done warm-air drier usefulness, turns off the K switch of heater element 1
2Then can make air-cooler uses.
It is continuous with another input of NAND gate 10 to add digital timing circuit in the control circuit of the present utility model, can make the timing, the gap working method regularly that the utlity model has the multiple time, installs the anti-tumbler switch K that joins with power supply on housing 2 additional
3, this machine is shut down when falling automatically.Install the thermosensitive bimetal switch N with power series in the shell additional, can make these facility organic in the function of protection automatically during temperature overheating.
