Description

Technical Field

[0001] The present invention relates to the technical field of gas pizza ovens, and particularly to a gas pizza oven with a temperature measuring function. Background Art

[0002] For the gas pizza ovens on the market, their operating temperature can reach 400 - 500 degrees Celsius. It is necessary to detect the temperature of the pizza oven to cook pizzas of different flavors.

[0003] At present, there are mainly two ways to detect the temperature of the pizza stone in the pizza oven. One is to use a special infrared gun to test the pizza stone. This solution requires an additional purchase of a special infrared gun, and when in use, it can only feedback the single detected temperature and cannot continuously feedback the actual temperature of the pizza stone. For some pizza ovens with a furnace door, the furnace door is also required to measure the temperature of the pizza stone, which will cause the temperature of the pizza stone to drop.

[0004] The other is to install a mechanical thermometer on the pizza oven to feedback the temperature of the pizza stone. However, the temperature of the pizza stone feedback by the thermometer has a large deviation, generally with a deviation of ≥±30°C. For some pizza ovens with a rotatable pizza stone, it is difficult for the mechanical thermometer to directly detect the pizza stone. Moreover, the instrument value of the mechanical thermometer is not convenient for users to view. For some pizza ovens with a fixed pizza stone, a temperature sensor and a screen are used in cooperation, and the screen displays the temperature data of the pizza stone. However, the screen is installed on the furnace body and is affected by the high temperature environment of the furnace body, with a short service life and difficult maintenance and replacement. Moreover, the temperature sensor and the screen need to set up corresponding power supply circuits, making the structure of the gas pizza oven more complex. Summary of the Invention

[0005] The purpose of the present invention is to provide a gas pizza oven with a more reliable power supply structure.

[0006] The purpose of the present invention is achieved as follows.

[0007] A gas pizza oven with a temperature measuring function includes a furnace body. A cooking cavity is provided inside the furnace body. A temperature detection device is provided corresponding to the cooking cavity of the furnace body. A detection and control device is provided inside the furnace cavity.

After the convex portion is inserted into the concave portion, the first inclined surface and the third inclined surface are in contact, and the top of the limiting portion abuts or is close to the third inclined surface. The convex portion is easily inserted into the concave portion, and the fixing bracket stably supports the display device. The limiting portion prevents the display device from flipping and detaching from the fixing bracket to a certain extent.
