Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, a gas-electric oven comprises an oven body 1 and a heat insulation board 5. The bottom surface of the oven body 1 is symmetrically distributed near the four corners and fixedly connected with legs 2. The oven body 1 is provided with an installation chamber, in which a gas stove head 7 is fixedly installed, and an air valve 12 is connected to the air inlet end of the gas stove head 7. The heat insulation board 5 is arranged in the installation chamber, and the heat insulation board 5 is fixedly installed above the gas stove head 7. A plurality of hot air holes 8 are opened on the heat insulation board 5. An electric heating tube 6 is fixedly installed on the heat insulation board 5, and the extension track of the electric heating tube 6 bypasses the opening position of the hot air hole 8. An electric control board 10 for controlling the temperature and switch of the electric heating tube 6 is fixedly installed on the outer side of the oven body 1. The gas valve 12 is provided with a switch 13 for controlling the switch of the electric control board 10, and the gas valve 12 is provided with a switch 2 14 for controlling the switch of the gas valve 12.

[0022] The switch 1 13 and the switch 2 14 are both electromagnetic switches. The switch 1 13 is electrically connected to the gas valve 12 , and the switch 2 14 is electrically connected to the electric control board 10 .

[0023] An igniter 11 is fixedly connected to the outer shell of the oven body 1. One end of the igniter 11 is provided with a connection port for connecting to an external gas source. The other end of the igniter 11 is connected to the gas stove head 7 through a gas valve 12. The gas valve 12 is fixedly installed on the oven body 1.

[0024] A temperature sensing rod 9 is provided on the oven body 1. The temperature sensing rod 9 passes through the end surface of the oven body 1. One end of the temperature sensing rod 9 is arranged in the installation chamber. The temperature sensing rod 9 is abutted against the electric heating tube 6 to sense the temperature change of the electric heating tube 6. The temperature sensing rod 9 is electrically connected to the electric control board 10.

[0025] A cover plate 3 is hinged on the oven body 1, and a handle 4 is fixedly connected to the cover plate 3 for facilitating opening and closing of the cover plate 3. When not in use, the cover plate 3 can prevent dust from falling on the electric heating tube 6, thereby avoiding affecting the heating capacity of the electric heating tube 6.

[0026] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0027] When the gas stove head 7, i.e., gas, is used as a heat source, the switch 13 is closed to cut off the power supply to the electric control board 10, which cuts off the power supply to the electric heating tube 6, and the electrical system of the entire device is completely shut down to ensure the safety of gas use. At the same time, the switch 2 14 turns on the gas valve 12, and the igniter 11 ignites the gas stove head 7 to start working. A plurality of hot air holes 8 are opened on the heat insulation board 5, and the extension track of the electric heating tube 6 bypasses the opening position of the hot air holes 8. The hot air holes 8 can be used for the bright spots on the gas stove head 7. The fire transfers heat, and the hot air hole 8 can prevent the open flame from directly burning the electric heating tube 6, thereby preventing the electric heating tube 6 from being damaged. At the same time, there is no need to remove the electric heating tube 6 when using the gas stove head 7, so it is easy to use. When the electric heating tube 6, that is, electricity, is needed to be used as a heat source, the switch 2 14 is disconnected to cut off the gas source, and the switch 1 13 is turned on to energize the electric control board 10 and the electric heating tube 6, and the temperature sensing rod 9 can transmit the temperature of the electric heating tube 6 to the electric control board 10, so that the temperature of the electric heating tube 6 can be adjusted through the electric control board 10.

[0028] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
