Abstract

PURPOSE:To improve the convenience of usage, ease of cleaning, etc. by providing a heating chamber, a circulation fan, a bread vessel, a fastening click attached to the its mounting and a hook which engages with the fastening click. CONSTITUTION:Since the bread vessel 11 can be fixed in place in the heating chamber 1 by engaging its fastening click 13 extending from the lower outer part of the mount 12 fixedly attached to the vessel 11 with a hook 14, the hole for fastening the bread vessel 11 does not need to be in the bottom of the heating chamber 1. Moreover, since the lower heater is eliminated from the heating chamber 1 on account of the usage of the upper heater 6 and the lower flat heater 8, the heater will not get in the way at the time of attaching and detaching the bread vessel 11. After the kneading and primary fermentation, the dough is divided and shaped. The dough is then set in the heating chamber 11, and is subjected to processes from the secondary fermentation through baking up as the upper heater 6 and the lower flat heater 8 are activated and the air is forcibly circulated by means of a circulation fan 7.

It is fixed to the bottom of the heating chamber with the fixing claw provided on the outer surface of the lower part.

A hook piece that engages with the fixing claw is provided.

(for production) With the above configuration.

(at) The bread container can be fixed in the heating chamber by engaging the fixing claw provided on the outer surface of the lower part of the support base fixed to the container with the hook piece fixed to the bottom of the heating chamber.
There is no need to make holes in the bottom of the heating chamber for fixing the bread container.

(bJ using the upper heater and lower flat heater.

The lower heater is removed from the heating chamber so that the heater does not get in the way when attaching and detaching the ζ-n container.

(C) After kneading the dough for sweet bread, pizza, etc., and performing the primary fermentation in a bread container.
