[0026] The following will be combined Figure 1-Figure 5 The present invention is further illustrated by the following embodiments.
[0027] This embodiment discloses an induction cooker-oven integrated cooker that recovers and reuses heat energy.
[0028] Reference Figures 1 to 3The induction cooker-oven integrated stove for heat recovery and reuse comprises a housing 8 and an induction cooker 1, a first oven 21 and a second oven 22 which are sequentially arranged on the housing 8 from top to bottom, wherein the oven panel of the induction cooker 1 is exposed on the top surface of the housing 8, so that it is convenient to use the induction cooker 1 to cook on the top of the housing 8, and the doors of the first oven 21 and the second oven 22 are arranged on the front surface of the housing 8, so that it is convenient to take and put food and cook on the front surface of the housing 8. An exhaust port 4 is arranged on the top surface of the housing 8, and the first oven 21 and the second oven 22 are respectively connected to a first exhaust pipe 31 and a second exhaust pipe 32, and the other ends of the first exhaust pipe 31 and the second exhaust pipe 32 are connected to the exhaust port 4, and the first oven 21 and the second oven 22 discharge the hot air generated during the cooking process through the first exhaust pipe 31 and the second exhaust pipe 32 respectively. The housing 8 is provided with a preheating box 5, which is mounted above the exhaust port 4. The preheating box 5 is used to preheat liquid oil or melt solid oil in advance, so that the user can prepare the cooking oil needed for frying in advance when cooking "bake first and then fry" dishes. In addition, since the preheating box 5 is arranged above the exhaust port 4, during the baking process of the dishes, the preheating box 5 can utilize the waste heat generated by the first oven 21 and the second oven 22, thereby recycling the heat energy of the first oven 21 and the second oven 22.
[0029] Reference Figures 1 to 3 , a connecting pipe 6 is connected between the second exhaust pipe 32 and the first oven 21, a selection valve is provided at the connection position between the connecting pipe 6 and the second exhaust pipe 32, the selection valve controls the heat of the second oven 22 to move to the end of the second exhaust pipe 32 or to the connecting pipe 6, and a switch valve is provided at the connection position between the connecting pipe 6 and the first oven 21, the switch valve controls the connection or blocking between the connecting pipe 6 and the first oven 21. Through the above configuration, when the first oven 21 and the second oven 22 bake the same food, by controlling the selection valve and the switch valve, the second oven 22, the second exhaust pipe 32, the connecting pipe 6 and the first oven 21 are connected in sequence, so that the first oven 21 can use the heat of the second oven 22 to achieve energy saving effect, thereby further recycling the heat energy of the second oven 22. When the first oven 21 and the second oven 22 bake different food, in order to avoid taste crosstalk, the connecting pipe 6 is blocked by controlling the selection valve and the switch valve.
[0030] Reference Figures 1 to 5A top cover 7 is movably provided on the top of the shell 8. When the induction cooker 1, the first oven 21 or the second oven 22 is needed to cook dishes, the user needs to open the top cover 7. When the cooking is completed and the dishes need to be kept warm, the top cover 7 is closed and covers the exhaust port 4 and the oven panel of the induction cooker 1. The dishes that need to be kept warm are placed in the first oven 21 or the second oven 22. At this time, the dishes in the oven can be kept warm by utilizing the waste heat of the induction cooker 1 and / or the oven, thereby recycling and reusing the heat energy of the induction cooker 1 and / or the oven.
[0031] In summary, by installing a preheating box 5 on the exhaust port 4, connecting a connecting pipe 6 between the first oven 21 and the second oven 22, and providing a top cover 7 on the top of the outer shell 8, the induction cooker 1-oven integrated stove of the present invention can recycle and reuse the heat energy of the induction cooker 1 and the oven, effectively utilize the waste heat generated during the heating process of the induction cooker 1 and the oven, and avoid wasting a large amount of heat energy during the cooking process.
[0032] Reference Figure 3 The first exhaust pipe 31 and the second exhaust pipe 32 are respectively connected to the top of the back of the first oven 21 and the second oven 22. Since hot air tends to flow upward, the arrangement of the first exhaust pipe 31 and the second exhaust pipe 32 can facilitate the discharge of heat in the first oven 21 and the second oven 22. In addition, the connecting pipe 6 is connected to the bottom of the back of the first oven 21, so that the distance between the upper end of the connecting pipe 6 and the lower end of the first exhaust pipe 31 is long, so that the first oven 21 can fully utilize the waste heat of the second oven 22 and improve the energy saving effect.
[0033] Reference Figure 3 and Figure 5 Although the heat inside the first oven 21 and the second oven 22 can be discharged through the first exhaust pipe 31 and the second exhaust pipe 32, a part of the heat from the first oven 21 and the second oven 22 will still overflow into the shell 8, causing a certain amount of heat inside the shell 8. For this reason, a heat dissipation hole 9 is opened on the top of the back side of the shell 8. The heat dissipation hole 9 of the shell 8 is used to improve the heat dissipation efficiency of the shell 8, avoid overheating inside the shell 8, and avoid affecting the normal operation of the first oven 21 and the second oven 22.
[0034] Reference Figure 1 and Figure 4, the top cover 7 is hinged to the top of the shell 8 to achieve the effect of convenient opening and closing. In this embodiment, the top cover 7 is hinged to the left or right side of the top of the shell 8 to avoid blocking the opening of the oven and the heat dissipation of the shell 8. Specifically, a mounting ring is provided at the top of the shell 8, and the edge of the top cover 7 is hinged to the edge of the mounting ring. When the top cover 7 is closed, the bottom of the top cover 7 abuts against the top of the mounting ring. In other embodiments, the top cover 7 can also adopt other installation methods, such as plug-in, as long as the opening and closing of the top cover 7 can be achieved. Further, the inner side of the top cover 7 is paved with a thermal insulation film to improve the thermal insulation effect when the top cover 7 is closed. In this embodiment, the thermal insulation film is a ceramic coating film, which has excellent heat insulation and high temperature resistance. In addition, a sealing ring is provided at the bottom of the top cover 7, which can reduce the heat lost from the gap during thermal insulation and improve the thermal insulation effect.
[0035] Reference Figure 3 The first exhaust pipe 31 and the second exhaust pipe 32 are both arranged in the outer shell 8, which improves the concealment of the first exhaust pipe 31 and the second exhaust pipe 32, on the one hand reduces the occupied space of the entire stove, and on the other hand improves the protection effect of the first exhaust pipe 31 and the second exhaust pipe 32.
[0036] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
