In figure: 1, lunch box body, 2, lunch box inner bag, 3, cover of the lunch box, 4, semiconductor chilling plate, 5 drive circuits.
Detailed description of the invention
nullEmbodiment 1、As shown in Figure 1，The present embodiment is a kind of heating/cooling lunch-box，Including lunch box body 1、The lunch box inner bag 2 being arranged in lunch box body 1 and cover of the lunch box 3，Lunch box inner bag 2 is the inner bag of a kind of insulation，Such lunch box inner bag 3 kind is a lot，Typically can use heat-preservation liner or other heat-preservation liner of double-layer stainless steel，In the present embodiment，The sidewall of lunch box inner bag 2 uses double-layer stainless steel the most permissible，The bottom of lunch box inner bag 2 is the electrical insulator material of one piece of planar shaped but is the base plate of good heat conducting material，Semiconductor chilling plate 4 it is provided with on the downside of low plate，Utilize this electrical insulator material but be that the heat on semiconductor chilling plate 4 can be sent in lunch box by the base plate of good heat conducting material，Or the heat in lunch box is delivered on semiconductor chilling plate 4，To realize semiconductor chilling plate 4 to heating in lunch box or freezing.Cover of the lunch box 3 can have a lot according to the shape of lunch box body 1, in the present embodiment, only requires that lunch box inner bag 2 is sealed by cover of the lunch box 3.
In the present embodiment, the drive circuit of semiconductor chilling plate 4 is arranged on drive circuit board 5, is provided with the cold and hot switching switch that the sense of current of semiconductor chilling plate 4 is flow through in switching on drive circuit board 5.By cold and hot switching switch, can control heating/cooling lunch-box is refrigeration or heating, the heating/cooling lunch-box of the present embodiment is the lunch box of a kind of applicable city white collar needs, this heating/cooling lunch-box band meal is utilized, due to the most long, therefore to mealtime at noon when city white collars are gone to work morning, need to carry out cold preservation, now, power up and by cold and hot switching on-off control, lunch box is freezed, make the lunch cold preservation being saved in lunch box.When having a meal at noon, then heated in lunch box by cold and hot switching on-off control, thus can have the food of heat.
In the present embodiment, utilizing semiconductor chilling plate can carry out the function freezed and heat, the size of this semiconductor chilling plate is little, can make the refrigerator that volume is little less than 1cm；Lightweight, mechanical running part, noiselessness in work, aneroid, gas working media, thus free from environmental pollution, cooling parameters is not affected by direction in space and gravity, under the conditions of big mechanical overload, it is possible to normally work；By regulating the size of operating current, conveniently adjusted cooling rate；By the switching sense of current, but refrigerator is changed into from refrigerating state and heats duty；Speed of action is fast, and service life is long, and is prone to automatically control.
In the present embodiment, drive circuit board 5 is additionally provided with control circuit, lunch box inner bag 2 wall is additionally provided with the temperature sensor of the temperature detected in real time in lunch box, the output connection control circuit of temperature sensor, the electric current of the semiconductor chilling plate 4 described in the real time temperature of control circuit C.T sensor detection and design temperature control.
At present, heating/cooling lunch-box required precision own to refrigerated storage temperature and heating-up temperature itself is not the highest, the temperature of food in lunch box can be measured in real time by temperature sensor, if when cold preservation, refrigerated storage temperature is more reasonable when 10 degree Celsius, when heating, the temperature of food is preferable when 60 degree Celsius, therefore, control circuit can be configured, when cooling, when food temperature in lunch box is Celsius less than 10 degree, semiconductor chilling plate can be controlled quit work, but when control circuit detects that the real time temperature detected by temperature sensor is Celsius higher than refrigerated storage temperature such as 15 degree, control semiconductor chilling plate and continue refrigeration until the food temperature in lunch box is Celsius less than 10 degree.
It addition, in the present embodiment, be additionally provided with the LED display of the real time temperature that the temperature sensor described in display detects outside lunch box body 1, so can be visually observed that the real time temperature in lunch box.
Due at present, the running voltage of semiconductor chilling plate is usually 12V, office can provide most be exactly the DC source of 5V, it is usually at USB interface, the USB interface of office is a lot, as the office equipment such as computer have USB interface, additionally, the USB interface that the charger of mobile phone all uses at present, present portable mobile phone stand-by power supply just has USB interface, but the power supply of 12V is the most fewer and feweri, therefore, in the present embodiment, in order to make heating/cooling lunch-box not want other band 12V DC source, drive circuit board 5 is provided with usb circuit and the 5V DC power signal in usb circuit is converted into the DC/DC circuit of 12V DC source required for semiconductor chilling plate 4.So, white collars just can be gathered materials on the spot the USB interface power supply using general USB line just can connect computer or other office equipment in office.
At present, outdoor activity are flourish, if using this lunch box in the wild, the most do not carry portable stand-by power supply, the most also to use solar energy, therefore, in the product of the present embodiment, also include one group of auxiliary equipment, such as sun-generated electric power, therefore, also including solar powered module in the heating/cooling lunch-box of the present embodiment, solar powered module is connected with drive circuit board 5 by described usb circuit.Sun-generated electric power is utilized to provide electric power for semiconductor refrigerating heating.
