Referring to FIGS. 2 and 3, the oven apparatus of the first embodiment of the present invention comprises a body 1, a heating unit 2, at least one holding member 3, and a turbulent heat storage unit 4. The inside of the body 1 defines an accommodating space 11 for accommodating the heating unit 2, the loading member 3 and the turbulent heat storage unit 4; the top of the body 1 forms an exhaust port 12, the exhaust port 12 is connected to the accommodating space 11; a side wall of the body 1 defines an opening 13 and is pivotally connected to the cover 14 , the opening 13 communicates with the accommodating space 11 , and the cover 14 is pivoted to cover the opening 13 . Moreover, the inner side wall of the body 1 can also be combined with a plurality of positioning members 15 to support the carrying member 3.

The heating unit 2 is mainly configured to generate heat to heat a food to be baked. The heating unit 2 is fixed in the accommodating space 11 of the body 1 and has a lower heater 21 and an upper heater 22. As shown in FIG. 3, the lower heater 21 is located below the upper heater 22, and the upper heater 22 is closer to the exhaust port 12 of the body 1 than the lower heater 21; wherein the lower heater 21 and the lower heater 21 The upper heater 22 is selected from a gas heater or an electrothermal heater, such as a gas furnace, a heating rod or an electron heating chip. In the embodiment, the lower heater 21 is preferably a gas. a heater, and the lower heater 21 has a conduit 211 for conveying liquefied petroleum gas or natural gas to the heater 2, and the upper heater 22 is preferably an electrothermal heater controlled The method is a technology that is controlled by the general prior art, and therefore will not be described again. The lower heater 21 and the upper heater 22 respectively have the advantages of a gas heater and an electrothermal heater, wherein the lower heater 21 can effectively provide heat energy to heat the food to be baked, and the upper heater is matched. 22 timely adjustment, the ingredients can be hooked on heat, can also improve the aesthetic effect of the ingredients after baking.

The loading member 3 is mainly for holding a food to be baked, preferably selected from a tic-tac or a mesh structure. The loading member 3 is coupled to the inner side wall of the body 1, preferably disposed on the positioning member 15 of the body 1, and between the lower heating 21 and the upper heater 22; The piece 3 can be pulled out from the receiving space 11 of the body 1 by the opening 13 of the body 1 to facilitate the user to take out the baked food.

Referring to FIGS. 2 and 3 again, the turbulent heat storage unit 4 is fixed in the accommodating space 11 of the body 1 and is interposed between the exhaust port 12 of the body 1 and the upper heater 22 . As shown Description

As shown in FIG. 3, the turbulent heat storage unit 4 of the present invention can divide the accommodating space 11 into two regions, which are respectively a heat collecting area 111 and a row of hot areas 112, and the heat collecting area 111 is located at the 4 Below the special heat storage unit 4, the heating unit 2 and the holding member 3 are located in the heat collecting portion 111, so that the food placed on the holding member 3 can be uniformly heated in the heat collecting portion 111. The heat rejection zone 112 is located above the turbulence heat storage unit 4 for the exhaust port 12 of the body 1 to communicate with the heat rejection zone 112.

Furthermore, the accommodating space 11 also forms an air flow path 41 between the heat collecting area 111 and the heat discharging area 112 to connect the heat collecting area 111 and the heat collecting area 112 by the turbulent heat storage unit 4. The air flow passage 41 of the present embodiment is a gap between the outer side wall of the spoiler heat storage unit 4 and the inner side wall of the body 1. The hot air in the heat collecting portion 111 thus enters the row via the air flow passage 41. The hot zone 112 is finally discharged outside the body 1 through the exhaust port 12 and enters the outside air, whereby the turbulent heat storage unit 4 effectively extends the flow path of the hot air, wherein the heat collection is particularly The hot air in the central portion of the zone 111 must bypass and bypass the spoiler heat storage unit 4 and flow through the gas flow path 41 to the exhaust port 12, so that the temperature of the heat collecting zone 111 is no longer due to heat. The air is quickly dissipated and drops significantly, and the heating unit 2 does not need to be continuously heated to maintain the baking temperature, that is, the heating time and the number of times of the heating unit 2 are shortened to achieve energy saving effect.

Referring to FIGS. 4 and 5, when the oven apparatus of the first embodiment of the present invention is used, the foodstuff is placed on the loading member 3 from the opening 13 of the body 1, and is generated by the heating unit 2. Heat is baked until cooked. As shown in FIG. 4, both the lower heater 21 and the upper heater 22 start to generate heat energy, whereby the oven device can quickly reach a predetermined baking temperature, and the bottom and the top of the food material can simultaneously receive heat. The spoiler heat storage unit 4 of the present embodiment may be a separator having a heat storage function, and the separator may preferably be selected from a metal or a high ratio. The material is made of heat or the like, such as copper or stone, so that the turbulent heat storage unit 4 can be stored while the lower heater 21 and the upper heater 22 are both open. The book stores heat energy, and avoids a large amount of heat energy that is not absorbed by the food material, which is carried out of the body 1 through the exhaust port 12 of the body 1, thereby effectively reducing energy consumption. As shown in FIG. 5, when the food material is about to finish baking, the present invention can turn off the upper heater 22 because the heat energy is not required to be provided, and the heat is released by the turbulent heat storage unit 4 instead of the upper heating. The function of the device 22 is not only to reduce the energy cost of the upper heater 22, but also to effectively utilize the thermal energy stored in the turbulent heat storage unit 4, and to avoid the situation in which the food material is scorched due to excessive heating.

Referring to FIG. 6 to FIG. 8 , the oven device of the second embodiment of the present invention forms an air flow channel 4 该 between the heat collecting region 111 and the heat exhausting region 112 by the turbulent heat storage unit 4 . The channel 41 is a plurality of bypass holes that penetrate the spoiler heat storage unit 4. As shown in FIG. 6, the hot air in the heat collecting portion 111 of the present embodiment flows into the heat discharging portion 112 via the air flow passage 4, and the turbulent heat storage unit 4 can thereby absorb and flow through the air flow passage 41. The heat of the hot air. Since each of the bypass holes constituting the air flow passage 41 is in a meandering curved shape, the hot air of the heat collecting portion 111 flows into the exhaust port 12 through the respective bypass holes, thereby prolonging the hot air. The effect of the flow route.
