Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
As shown in Figure 1, the heat preserving antistaling food cover that the utility model embodiment provides, comprises semiconductor refrigerating backing 1, control panel 4, power switch 5, food cover body; Food cover body comprises food cover internal layer 11, food cover skin 12; Semiconductor refrigerating backing 1 is two; Food cover body is an airtight cover body; On food cover body, be provided with putting hole, it is indoor that putting hole is positioned at food cover body cavity, and semiconductor refrigerating backing is all fixedly installed in putting hole, and two semiconductor refrigerating backings are placed side by side.
In the time that power switch is opened fresh-keeping state, semiconductor refrigerating backing is switched on, and starts refrigeration work, and in the time that power switch is opened keeping warm mode, electric current changes, and semiconductor refrigerating backing starts heating work.
Two chip semiconductor refrigeration backing both sides are provided with fin 2, and fin has the heat of absorption and carries out heat conducting ability, and it is indoor that fin is all positioned at food cover body cavity, and fin and food cover body pass through fastened by screw.
Power switch 5, power line 6, power supply indicator 15 are all connected with control panel, appear at food cover skin; The power supply adaptor that control panel 4 is made up of transformer and rectification circuit, power supply adaptor is a kind of power supply conversion equipment, and city's alternating current of 220V is converted to suitable electric pressure, has ensured safe handling magnitude of voltage.It is city's power supply that power line is used for connecting external power source; Two power supply indicators appear at food cover skin, because power switch is third gear waved switch, just can control insulation and fresh-keeping two states so only need a power switch simultaneously, when power switch is during in fresh-keeping state, green light in power supply indicator, shows that heat preserving antistaling food cover is in fresh-keeping state, when power switch is during in keeping warm mode, when red in power supply indicator, shows that heat preserving antistaling food cover is in keeping warm mode.
It is indoor that radiator fan 3 is also placed in food cover body cavity, and radiator fan and control panel electrically connect simultaneously, needs only power switch in opening, and radiator fan just comes into operation; Meanwhile, on the chamber that comprises semiconductor refrigerating backing, control panel, power switch, fin, radiator fan, insulation temperature detect switch (TDS) and fresh-keeping temperature detect switch (TDS), there is air-vent 14.
The unnecessary heat absorption that fin produces when backing is worked for semiconductor refrigerating backing is freezed is also carried out heat transmission, radiator fan and air-vent have accelerated whole heat radiation process, make whole heat preserving antistaling food cover thermal diffusivity better, thereby reach heat preserving antistaling effect better, ensured this kind of security that heat preserving antistaling food cover uses.
Fresh-keeping temperature detect switch (TDS) 8 is two Kick type temperature detect switch (TDS)s with insulation temperature detect switch (TDS) 9, and Kick type temperature detect switch (TDS) is a kind of temperature controller of bimetal leaf as the temperature module of using.
When after power-on switch keeping warm mode, electrical equipment normally moves, when heatsink temperature reaches the operating temperature that triggers insulation temperature detect switch (TDS), the bimetal leaf in Kick type temperature detect switch (TDS) is heated and produces internal stress and action rapidly, opens contact, cut off circuit, thereby play temperature control function, in the time that electrical equipment is cooled to reset temperature, contact is automatically closed, semiconductor refrigerating backing works on, and recovers normal operating conditions; And in the time that power switch is opened keeping warm mode, control fresh-keeping state of switch and disconnect in power switch, fresh-keeping temperature detect switch (TDS) also disconnects simultaneously, and insulation temperature detect switch (TDS) and fresh-keeping temperature detect switch (TDS) can not be worked simultaneously.This Kick type temperature detect switch (TDS) can better be controlled the scope of temperature, ensures that temperature is in one section of fixed value, has ensured the security using, and the stable performance of this Kick type temperature detect switch (TDS), and precision is high, and volume is little, lightweight, long service life.
In order to make food cover be easier to take, handle 7 has been installed, the two ends of handle are fixedly connected with same screw with food cover body and fin; Simultaneously in order to make the heat preserving antistaling food cover of the present embodiment there is better heat preserving antistaling effect, between food cover skin and food cover internal layer, accompany insulating sponge layer 10, again in order to ensure the sealing of heat preserving antistaling food cover, be provided with base insulating sponge 13 on food cover base, this base insulating sponge is connected with the outer base of food cover surrounding.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., all should be included in protection domain of the present utility model.
