TH60920B - Food seasoning with heat - Google Patents

Abstract

DC60 (18/09/52) The heated cooking unit is located behind the rear wall of the inner housing containing the cooking chamber. The heated chamber has a fan and heaters for circulating hot air to the cooking chamber. The fan consists of a jet fan assembled with various impellers arranged circumferentially and front and rear diaphragm plates positioned on the front and rear axes of the impellers. The heater consists of a heater shell and radial fins, arranged to enclose opposite areas of the front and rear diaphragm plates. This arrangement of heaters improves the heat exchange ratio and therefore allows for a shorter heating time inside the cooking chamber. The heater consists of a heater shell and radial fins, and is arranged to surround opposite areas of the front and rear steel plates. This arrangement of heaters improves the heat exchange ratio and therefore allows for a shorter temperature rise inside the cooking chamber.

Revised 08/07/2016 1. Food preparation equipment consisting of a cooking chamber with an open front surface for food ingredients entry/exit, and a rear plate opposite the entry/exit, with the front surface on the user's side. A door capable of operating between a closed state at the cooking chamber entry/exit and an open state at the open cooking chamber entry/exit. Entry and exit points are positioned on the rear plate of the cooking chamber. A fan is positioned outside the cooking chamber, behind the rear plate, drawing air into the cooking chamber from the entry, and exhausting air from the exit into the cooking chamber. There are also several main plate sections and blades, and decorative elements positioned on the main fan plate, behind the entry and extending forward from the fan plate, where the entry is fitted with several through-holes. The decorative elements are visible from the front in the open door state and in the fan's stationary state. 1. The cooking chamber is defined by the left and right side walls, the top wall, the bottom wall, and by a front opening opposite the rear wall. A door is provided to enclose this opening. The heating element of the cooking chamber consists of a lid placed on the rear wall to be positioned outside the cooking chamber and to form a hot air chamber along the rear wall. An inlet is placed on the rear wall to be positioned forward relative to the lid and to draw air from the cooking chamber to the hot air chamber. An outlet is placed on the rear wall to be positioned forward relative to the lid and to release air from the hot air chamber back into the cooking chamber. A centrifugal fan is placed inside the hot air chamber to draw air from the cooking chamber to the hot air chamber through the inlet and to release air from the hot air chamber back into the cooking chamber through the outlet. A fan motor drives the fan. An electric heater is placed inside the hot air chamber, where the fan includes a front and rear axial plates opposite the front plate and a number of movable impellers. The circumferential gaps between the front and rear plates of the thruster are sloped toward the rear relative to its direction of rotation, and at least some of the front and rear plates are circularly shaped and have air intakes around their center of rotation. Furthermore, heaters are positioned to enclose the opposite areas of the front and rear plates, exposing them to air being blown out from opposite areas.
