Pellet grill

A pellet grill, comprising:

• a grill body;
• a burning chamber, arranged in the grill body;
• a wire grid, arranged in the grill body, and arranged above the burning chamber;
• and
• a pellet inlet, formed in a lateral portion of the grill body,
• wherein a fire-proof partition plate is arranged between the wire grid and the burning chamber, and the fire-proof partition plate partitions an inner cavity of the grill body into an upper cavity and a lower cavity which are independent from each other, the burning chamber is arranged in the lower cavity, the wire grid is arranged above the upper cavity,
• a fire-pervious window is arranged on the fire-proof partition plate and is located above the burning chamber, and an opening and closing device for controlling the fire-pervious window to be opened to realize higher temperature or closed to realize lower temperature is arranged on the fire-pervious window, and
• an ash removal mechanism for removing ash accumulated in the burning chamber is arranged on the grill body,
• wherein the fire-pervious window is formed with a plurality of first fire-previous through grooves vertically penetrating through the fire-pervious window, the plurality of first fire-pervious through grooves are parallel to and spaced apart from one another in a front-back direction, the opening and closing device comprises a cover plate which is attached to and covers the fire-pervious window, the cover plate is formed with second fire-pervious through grooves vertically penetrating through the cover plate and matched with the first fire-pervious through grooves, each of the second fire-pervious through grooves is correspondingly arranged above a respective one of the first fire-pervious through grooves, and the cover plate is movably arranged on the fire-pervious window in the front-back direction;
• when the first fire-pervious through grooves and the second fire-pervious through grooves are vertically aligned, the fire-pervious window is opened to realize higher temperature;
• and when the first fire-pervious through grooves and the second fire-pervious through grooves are vertically staggered, the fire-pervious window is closed to realize lower temperature,
• wherein the fire-pervious window is a rectangular protrusion arranged on the fire-proof partition plate, the first fire-pervious through grooves are formed in an upper surface of the rectangular protrusion, two side surfaces of the rectangular protrusion are arranged in the front-back direction and are perpendicular to a front mounting plate of the grill body, a rectangular cover matched with the rectangular protrusion is arranged on the cover plate and protrudes upwards, the second fire-pervious through grooves are formed in the rectangular cover which covers the rectangular protrusion, a lower surface of the rectangular cover is attached to the upper surface of the rectangular protrusion, two inner side surfaces of the rectangular cover are attached to corresponding side surfaces of the rectangular protrusion respectively, and a vertical distance between an inner front surface of the rectangular cover and an inner back surface of the rectangular cover is greater than a vertical distance between a front surface of the rectangular protrusion and a back surface of the rectangular cover.
