Description of drawings
Below in conjunction with accompanying drawing and enforcement the utility model is further specified.
Fig. 1 is schematic circuit diagram of the present utility model.
Fig. 2 is the sectional structural map of the utility model embodiment.
In Fig. 1, CZ is gang socket.K is three a change-over swith, and these three promptly provide refrigeration, close, heat three mode of operations.LB is a cold plate, and D is the rectifier of radiator fan, and FS is a radiator fan.CZ introduces direct supply, and the electric power polarity on the connection of K switch control circuit and the cold plate LB, the rectifier D of radiator fan make radiator fan can not change polarity because of the polarity that changes LB, and the wind direction of radiator fan FS is outside.
In Fig. 2,1-loam cake, 2-inner bag, 3-heat-insulation layer, 4-heat-conducting plate, 5-shell, 6-cold plate (LB), 7-radiating gill, 8-radiator fan (FS), 9-change-over swith (K), 10--gang socket (CZ).
The specific embodiment
In Fig. 1, gang socket CZ connects three change-over swith K by circuit, and this switch has six contacts 1,2,3,4,5 and 6, and wherein contact 1,6 is communicated with, and contact 4,3 is communicated with, and is not communicated with between the contact 2,5.Contact 1,4 is combination hub CZ in succession, contact 2,5 connects the two poles of the earth of cold plate LB by lead, the input end of rectifier D also in parallel, radiator fan FS is connected on the mouth of rectifier D, and CZ introduces power supply by gang socket, among the change-over swith K, be in contact 1 and 2,4 and 5 positions of connecting mutually, the cold junction of cold plate LB freezes, and makes the drop in temperature of inner bag, and heat is discharged by radiator fan FS.Otherwise, in change-over swith K, be in contact 2 and 3,5 and 6 and connect, then the cold junction of cold plate LB then generates heat, and inner bag is heated, and radiator fan FS then discharges cold.The effect of rectifier D is that the electric power polarity of radiator fan FS can not changed with the switch of K, makes radiator fan energy normal operation.
In embodiment illustrated in fig. 2, the structure of this thermos cup is: it comprises a container, be used for splendid attire food etc., it is shaped to inner bag 2, on inner bag 2 outside bottom surfaces, heat-conducting plate 4, cold plate 6, radiating gill 7, radiator fan 8 etc. are installed successively, cold plate 6 is connected in as shown in Figure 1 the circuit, change polarity of voltage on the cold plate 6 by three change-overs swith 9, thereby change the cold and hot end of cold plate, make cold plate 6 that heat or cold are transmitted by described heat-conducting plate 4 and be inner bag 2, thereby the food of 2 li of inner bags is refrigerated or heats.
