Energy-saving bread maker

Abstract

The invention relates to an energy-saving bread maker, which comprises a shell. An upper cover is arranged on one side of the upper part of the shell, and a controller is arranged on the other side of the upper part of the shell; the bottom of the shell is provided with a motor; a baking chamber is arranged between the upper cover and the shell, and a bread barrel is arranged in the baking chamber; electrical heated tubes are uniformly arranged between the bread barrel and the baking chamber; the bottom of the bread barrel is provided with a stirring rod which is connected with the motor through a transmission system; and the outside of the baking chamber is provided with an insulating material layer. The insulating material layer is a metal material or a nonmetal material with thermal insulation capacity and heat reflection capacity, and is covered on the outer surface of the baking chamber through pressure casting, electroplating and spraying. The baking chamber is made of a metal sheet with high strength and the heat reflection capacity. In the invention, the outer surface of the baking chamber on the bread maker is fully covered with the insulating material layer, so that internal heat loss of the baking chamber is reduced, the energy efficiency ratio of the bread maker is improved, electrical elements in the shell are less influenced by a high temperature, and the service life of a product is effectively prolonged.

Description

technical field [0001] The invention relates to a bread machine, in particular to an energy-saving bread machine. Background technique [0002] Automatic bread machines have generally entered households in foreign countries and regions where pasta is the main food. This kind of bread machine can realize mixing, fermentation, baking, heat preservation, and complete the whole process of bread making, such as figure 1 As shown, it includes an outer shell 1, a baking chamber 2, a bread bucket 3, an electric heating tube 4, a stirring rod 5, a transmission system 6, a controller 7, and realizes stirring the noodles by controlling the transmission of the motor 8, and heating by controlling the electric heating tube 4, Toast the bread in the bread bucket. Chinese Patent Document No. CN101601548 disclosed a bread machine on December 16, 2009, which includes an oven body arranged in the fuselage. The oven body is provided with a bread bucket and a heating element, and the side of th...

Problems solved by technology

However, the oven body is generally made of a single-layer metal plate with a thickness of less than 0.5mm. When the oven body bakes bread, a large amount of heat is transferred to the air in the interlayer by the outer surface of the metal plate and taken out of the machine. A large amount of heat loss is caused, the energy efficiency is relatively low, and at the same time, the interlayer between the shell and the oven body is overheated, resulting in excessive temperature rise of the components in the control part of this space (such as electronic components on the control board, motors, etc.), which affects The long-term use of the control board may increase the cost due to the need for high-temperature components

At the same time, it sets a technical bottleneck of high ambient temperature for further increasing the bread baking temperature
