Description

Technical Field

[0001] The invention relates to the technical field of charcoal ovens, in particular to an automatic cleaning oven. Background Art

[0002] A charcoal grill is a device that uses charcoal as fuel for grilling and is widely used in outdoor barbecue, camping and catering industries.

[0003] A barbecue grill provided by publication number CN221411040U includes a support frame, a first barbecue grill body and a first grill door, the first barbecue grill body is installed on the top of the support frame, and the first grill body is hingedly connected to the first grill body; it also includes: air vents, which are opened on the left and right side walls of the first barbecue grill body, and a smoke exhaust pipe is fixed on the left side of the first barbecue grill body; a second barbecue grill body is fixed on the right side of the first barbecue grill body, and the second grill body is hingedly connected to the second grill door; a first placement plate is arranged inside the first barbecue grill body.

[0004] However, when grilling large pieces of meat, the above-mentioned barbecue oven places the meat on the first grill body and on the first placement plate for grilling. However, when grilling large pieces of meat, it is necessary to measure the core temperature inside the meat piece and maintain the core temperature at a suitable temperature to achieve a better grilling effect. However, when measuring the core temperature of the meat piece, the above-mentioned barbecue oven frequently opens the first oven door, causing the temperature inside the first oven body to drop rapidly, thereby reducing the grilling efficiency. Frequent temperature measurements make the grilling work more cumbersome, and the carbon ash cannot be automatically cleaned well, which is very troublesome. Summary of the invention

[0011] An opening and closing component is arranged in the exhaust pipe and is connected to the control mechanism. When food is placed on the oven body and the oven cover is closed, the inner push tube contacts the food. The inner push tube contracts into the temperature measuring tube to press the food, and at the same time, the temperature measuring probe is gradually exposed and inserted into the food to detect the temperature inside the food. When the temperature inside the food exceeds the set temperature, the control mechanism drives the opening and closing component to move downward, gradually opens the exhaust pipe, discharges the hot air in the oven body, and reduces the temperature inside the oven body. When the temperature inside the food is lower than the set temperature, the control mechanism releases the opening and closing component, closes the exhaust pipe, increases the temperature inside the oven body, and increases the temperature of the food. When the oven cover is opened, the inner push tube pushes the food to prevent the food from being hooked with the temperature measuring probe.

[0012] Preferably, a baking tray for placing food and a charcoal plate for placing charcoal are provided in the furnace body, rotating legs are provided at the bottom of the furnace body, and a handle is provided on the furnace cover.

When the oven cover is closed, the push plate contacts the food, causing the cylinder to shrink into the temperature measuring cylinder, so that the push plate presses the food under the push of the spring 1, and the temperature measuring probe extends out and inserts into the food. When the oven cover is opened, the spring 1 pushes the push plate to reset, pushing the food away from the temperature measuring probe, so that the temperature measuring probe is covered by the cylinder.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention comprises a furnace body, a temperature measuring component and an opening and closing component. The temperature measuring component comprises a displacement mechanism arranged in a furnace cover, a temperature mechanism arranged on the displacement mechanism and a control mechanism arranged on the displacement mechanism. The opening and closing component is arranged in an exhaust pipe and is connected with the control mechanism. The present invention arranges the temperature measuring mechanism so that after the furnace cover is closed, a temperature measuring probe is inserted into a piece of meat for temperature measurement. The arrangement of an inner push tube avoids interference of hot air in the furnace body with the temperature measuring probe. The push tube is also used to help the piece of meat and the temperature measuring probe to separate when the furnace cover is opened. The arrangement of the control mechanism and the opening and closing component automatically controls the temperature rise and fall in the furnace body, avoids sudden temperature drop in the furnace body, and ensures that the core temperature of the piece of meat is maintained at a suitable temperature, thereby improving the efficiency of baking and simplifying the steps of baking.
