Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figures 1 to 2, the fireplace capable of utilizing the residual heat of the oven comprises a main body 1, wherein a barbecue cavity 3 is arranged in the main body 1, and an electric heating element 31 is arranged in the barbecue cavity 3. The main body 1 is further provided with a display effect door 2, and the display effect door 2 comprises a protective layer 25, a display layer 24, a supporting layer 23, a sealing layer 22 and a heat insulation layer 21. A liquid crystal display 28 is disposed on the display layer 24. The display effect door 2 is also provided with a control panel 29. Display effect door 2 connect barbecue chamber 3, main part 1 in be provided with the intercommunication barbecue chamber 3's lower intake duct 11 and outlet duct 13, lower intake duct 11 on be provided with down inlet fan 12. The barbecue cavity 3 with be provided with solenoid valve 9 between the gas outlet channel 13, the display effect door 2 on be provided with the intercommunication the gas outlet of gas outlet channel 13, the gas outlet include last gas outlet 271 and lower gas outlet 272, the supporting layer 23 in be provided with air current passageway intercommunication 26 last gas outlet 271 with lower gas outlet 272, the gas outlet channel with be provided with filter 17 and solenoid valve 9 on the gas outlet junction. The addition of the filter 17 mainly prevents the gas introduced through the broiling chamber 3 from carrying impurities, which can be separated using the filter 17.
The main part 1 in still be provided with heat-retaining device, heat-retaining device include heat exchange box 4 and heat-retaining box 5, heat-retaining box 5 in be provided with pivot 51, pivot 51 on be provided with a plurality of bracing piece, the bracing piece on be provided with many vacuums foam metal 52, be provided with the electron thermometer on the many vacuums foam metal 52. The multi-cavity foam metal 52 is doped with an aluminum-paraffin composite material, the multi-cavity foam metal 52 can rotate into the heat exchange box 4 through a rotating shaft 51, an automatic door 41 is arranged between the heat exchange box 4 and the heat storage box 5, and the automatic door 41 is of a horizontal sliding type. The main body 1 is further provided with an upper air inlet duct 14, an upper air inlet fan 15 is arranged on the upper air inlet duct 14, the upper air inlet duct 14 is communicated with the heat exchange box 4, and a heating device 16 is arranged in the upper air inlet duct 14.
During the use, if only need indoor heating, and do not have heat energy when heat-retaining chamber 5, then can admit air through last air flue 14, let heating device 16 heat the air that gets into, after the heating is accomplished, hot-air is through heat exchange box 4, air outlet channel 13, the gas outlet discharges the external world, when exhausting, barbecue chamber 3 with the solenoid valve 9 between the air outlet channel 13 close, prevent that steam from getting into in barbecue chamber 3. While heating, the liquid crystal display 28 on the display effect door 2 may display the flame effect. If grilling is being performed, air enters from the lower air inlet channel 11, enters the grilling cavity 3 first, and carries excess heat out of the grilling cavity 3 into the outlet channel 13.
