It when the temperature that device 8 is fed back is lower, or needs to carry out heat-flash heating to food, switches to heat-flash mode；When need to food into
When row constant temperature thermal protection, constant temperature mode is switched to.Humidity control system is set mainly for temperature, by the temperature of setting
Key is risen and declined, realizes the regulation to desired temperature.The side of controller 5 is provided with the switch key of heating cushion, connects
Behind energization source, by switch key start and stop heating cushion, the switch key in the present embodiment can carry out circuit company according to the prior art
It connects, which is not described herein again.
Plug 7 in this implementation is the bipod attaching plug 7 for connecing alternating current, when specifically used, attaching plug 7 is inserted into slotting
Seat in, power on, heating cushion be laid on desktop, food is heated, the heating cushion can be widely applied to family and
In restaurant.In the present embodiment, silicon rubber high-temperature insulating layer 3 with a thickness of 1.5mm, protective layer 4 is to lead with a thickness of the PVC of 1mm
Heat leather.The thermally conductive leather of PVC has good heating conduction, can effectively pass to the heat that heating layer issues and be placed on heating
Utensil on pad guarantees good heating effect.In addition, the bottom surface setting of i.e. heating cushion is regular in the bottom surface of the thermally conductive leather of PVC
The tread plate of arrangement, the tread plate increase the adhesive force of heating cushion on the table, can be effectively to the anti-skidding fixation of heating cushion, enhancing
The whole safety used.In the bottom of heating cushion, it is provided with the aluminium foil compound pearl cotton as thermal insulation layer, and aluminium foil is multiple
It closes pearl cotton and is combined with the thermally conductive leather of PVC by high-temp epoxy sticker.Aluminium foil compound pearl cotton is also referred to as that " pearl cotton is multiple
Close aluminium film ", it is that have moisture-proof, sun-proof, heat-insulated, heat preservation energy-saving by the compound one layer of aluminium foil of Pearl wool material outer layer or internal layer
Etc. functions, and have excellent corrosion resistance, be widely used in the heat-insulated internal layer and family's interior trim of insulated bag
In.The flexible nature of aluminium foil compound pearl cotton and the flexibility of heating cushion in the present invention match, and pass through the then energy band that is combined with each other
Carry out better heat insulation effect, the cheap price of aluminium foil compound pearl cotton also reduces the production cost after mass operation.
Specifically when in use, the heat that the aluminium foil compound pearl cotton of heating cushion bottom can distribute heater 1 is set
It is effectively intercepted in its bottom, enables the significantly more efficient top for being transmitted to heating cushion of heat, i.e., contacted with heating cushion top surface
Food vessel bottom prevents the entire body heat dissipation on heating cushion two sides, avoids in vain loss of the heat from heating cushion bottom.It is logical
It crosses using the thermally conductive leather of silicon rubber flexible and PVC to the cladding of heater 1, realizes the superthin structure in heating cushion, so that plus
The lighter carrying of use of heat pad.Decorative appearance of the thermally conductive leather of PVC as luggage, clothes, vehicle seat and furniture itself,
Using in this present embodiment, making the use of heating cushion more neat and artistic, the need that modern pursues high-quality life taste are met
It asks.
It can also be first by the bottom of the pearl cotton side of aluminium foil compound pearl cotton and insulating layer 3 for thermal insulation layer in the present embodiment
Face is by high-temp epoxy glue laminating, then by the thermally conductive leather of PVC by whole outsourcing, can more increase heating cushion use it is clean and tidy.
