Technical Field
The invention relates to a fireplace, in particular to a barbecue and heating dual-purpose electronic fireplace.
Background
The fireplace belongs to equipment for heating by burning biomass in ancient times, and also has certain decoration and cooking functions. In modern society, a fireplace basically cancels a combustion heating mode, and generally adopts an electric heating mode which is more environment-friendly, energy-saving and safe. The electric oven is a kitchen appliance for baking food by utilizing radiant heat emitted by an electric heating element, the electric oven is high-power kitchen equipment, a large amount of energy is consumed and wind energy is needed to dissipate heat of the electric oven when the electric oven is used, and heat dissipated hot air can be directly discharged, so that the electric oven is very wasted. If the oven can be combined with the fireplace, the fireplace can utilize the heat-dissipating hot air generated when the oven works to heat in other time periods, so that the energy consumption can be reduced greatly, and the overall energy utilization rate is improved.

The fireplace is a product with double functions of heating and food barbecuing. For a common electric fireplace, the heating is mainly realized by heating air and then exhausting the hot air; in the case of a general oven, the barbecue of the oven mainly comprises that the electric heating element continuously heats the inside of the oven for a long time, and the air cooling and heat dissipation of the oven are required during the long time, so that a large amount of heat is wasted. The invention is that when barbecuing, the heat dissipation wind which needs to be exhausted to the outside is circulated again, the hot wind is blown into the heat exchange box, the heat energy is transferred into the porous foam metal through the heat exchange box, the porous foam metal is doped with the aluminum-paraffin composite material, the aluminum-paraffin composite material is a metal phase change heat storage material, and the aluminum-paraffin composite material can store more heat under the action of the porous foam metal. In order to ensure the durability of heat storage, an exhaust tube is further arranged on the heat exchange box and connected with a vacuum pump, and the heat exchange box is vacuumized through the vacuum pump when heat exchange is not needed, so that heat transfer is reduced. When indoor heating is carried out, cold air entering the heat exchanger can be blown out by hot air in the earlier stage, and the cold air is heated by the heating device until the stored heat is insufficient. The system can greatly improve the utilization rate of energy during barbecue, reduce the energy loss caused by heat dissipation during barbecue and simultaneously reduce the energy loss during indoor heating.
Compared with the prior art, this fireplace has the dual function of indoor temperature heating and food barbecue, and more importantly this fireplace can collect a large amount of waste heat that produces when saving the barbecue, carries out preliminary heating through these heats of release when carrying out indoor heating, has improved the whole rate of utilization of the energy, the very big waste that has reduced the energy.

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 using 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 solar heat collector is characterized in that a heat storage device is further arranged in the main body 1 and comprises a heat exchange box 4, two ends of the heat exchange box 4 are provided with a heat reservoir 41 in the heat exchange box 4, and an electronic thermometer is arranged on the heat reservoir 41. Heat reservoir 41 include many vacuums foam metal, many vacuums foam metal doping aluminium-paraffin combined material, heat transfer box 4 on still be provided with exhaust tube 52, exhaust tube 52 connect vacuum pump 5, main part 1 on still be provided with last air inlet duct 14, last air inlet duct 14 on be provided with air intake fan 15, last air inlet duct 14 intercommunication heat transfer box 4, last air inlet duct 14 in be provided with heating device 16. The suction pipe 52 communicates with the upper air intake duct 14. The joints of the heat exchange box 4, the upper air inlet channel 14 and the air outlet channel 13 are provided with electromagnetic valves 9.
During the use, if only need indoor heating, and when heat reservoir 41 does not have heat energy, 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 hot gas 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. At this time, the electromagnetic valve 9 between the air outlet channel 13 and the air outlet is closed, and the hot air enters the heat exchange box 4. The hot air can just flow into upper air inlet duct 14 after carrying out the heat exchange through heat reservoir 41, after the barbecue, does not have the air and after getting into heat transfer box 4, closes the solenoid valve of heat transfer box 4 both sides, starts vacuum pump 5, and the interior evacuation of heat transfer box 4 through exhaust tube 52, this kind of vacuum storage environment still in order to reduce the thermal giving off of heat reservoir 41 itself, prolongs thermal storage time. So that the heat reservoir 41
When needs indoor heating, and when heat reservoir 41 has heat energy storage, then can enter through last air flue 14, and cold air gets into and becomes hot air behind heat exchange box 4 through heat reservoir 41, and the heating is accomplished the back, through air outlet channel 13, air outlet discharge external world, in exhaust, barbecue chamber 3 with air outlet channel 13 between solenoid valve 9 close, prevent that steam from entering into in the barbecue chamber 3. When the heat reservoir 41 is not sufficiently charged, i.e. the electronic thermometer shows too low a temperature, the incoming air is heated by the heating device 16. Through the arrangement, the utilization rate of heat energy can be the highest, and the waste of energy is greatly reduced.
