Piece, floor push, described floor push and the second electric heating piece, are placed in blanket body；Blanket body is provided with wire connection controller.Institute
The controller stated is provided with Transformer Rectifier circuit, be additionally provided with for receiving infrared-ray sensor, temperature sensor, floor push letter
Number and control the first electric heating piece, the second electric heating piece heating circuit.
Beneficial effects of the present invention are mainly manifested in：In good heat-preserving function, energy-conservation does not influence desktop clean and tidy to tool.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the present invention.
Fig. 2 is the circuit diagram of one embodiment of the present invention.
Specific embodiment
1~2 pair of one embodiment of the present invention is further described below in conjunction with the accompanying drawings.
A kind of desk with heat-preserving function, including desktop warm-keeping device, ground warm-keeping device and controller 1.Described
Desktop warm-keeping device, including desktop, the first electric heating piece 2a, infrared ray sensor H, temperature sensor Rh；Described desktop is by face
Plate 3a and base plate 3b are constituted, described the first electric heating piece 2a, temperature sensor Rh, infrared ray sensor H be placed in base plate 3b and
Between panel 3a；Wherein, the first electric heating piece 2a is located at the center of desktop, and temperature sensor Rh is located at the first electric heating piece 2a's
At the 2cm of side；First electric heating piece 2a and temperature sensor Rh are sealed among panel 3a and base plate 3b；Described infrared ray sensing
Device H is located at desktop front so that the probe of infrared ray sensor H exposes the surface in front of desktop.
Described ground warm-keeping device, including blanket body 4, the second electric heating piece 2b, floor push K1, described floor push
K1, at least provided with 2, floor push K1 and the second electric heating piece 2b is placed in blanket body 4；Blanket body 4 is provided with the connection control of wire 5
Device 1.Described controller 1 is provided with Transformer Rectifier circuit 6, be additionally provided with for receiving infrared-ray sensor H, temperature sensor Rh,
The signal and the first electric heating piece 2a of control of floor push K1, the circuit of the second electric heating piece 2b heating.
Described controller 1, installed in the lower section of desktop；Connection between the wire 5 and controller 1 of ground warm-keeping device
It is provided with interface 7 so that wire 5 can be pulled up or plugged from controller 1.
Transformer Rectifier circuit 6 in controller 1, the safe dc electricity for the alternating current of 220V to be converted into 12V.Control
Variable resistor Rw, logical AND gate Q, relay J are additionally provided with device 1, its circuit connecting mode is as follows：
The signal output part of infrared ray sensor H is connected to an input Q-1a of logical AND gate Q by resistance R1；It is all of
Floor push K1 is in parallel, and the input Q-1a of logical AND gate Q is connected to also by resistance R1；One end of variable resistor Rw leads to
Cross resistance R2 connection positive sources, another input Q-1b of other end connection logical AND gate Q；One end of temperature sensor Rh
Connect the negative pole of power supply, the input Q-1b of other end connection logical AND gate Q；The output end Q-2 of logical AND gate Q, connects one
Relay J, relay J are for connecting or disconnecting the first electric heating piece 2a, the circuit of the second electric heating piece 2b.
Further, described controller is additionally provided with power switch K2.
Further, described floor push K1, using the floor push of DDR or other foot-operated touch-switch.
The working method of circuit is as follows：
Turn on the power switch K2.If before taking preceding desk, i.e. the light of infrared ray sensor H is blocked, now infrared ray
Sensor goes out high level, logical AND gate Q is also exported high level, relay J conductings, two electric heating piece electrified regulations.Work as heating
During to uniform temperature, temperature sensor Rh receives thermal resistance step-down, and now the input Q-1b of logical AND gate Q is low-level, logic
Low level is exported with door Q, relay J disconnects, and electric heating piece stops heating.
