Household bread maker

Abstract

The invention provides a household bread maker with an upper openable cover and double electric heating pipes. A cover body is hinged with a machine body; an upper open lining cavity formed by a metal plate is formed in the machine body; a bread barrel is arranged in the lining cavity; a lower electric heating pipe is fixedly arranged at the lower part of the lining cavity around the bread barrel; a cover lining formed by a metal plate is arranged in the cover body; an upper electric heating pipe is fixedly arranged inside the cover lining; when the cover body is buckled with the machine body, the upper electric heating pipe is positioned above a barrel opening of the bread barrel; and an electrical connecting wire of the upper electric heating pipe is led into the machine body by a power transmission connecting part of the machine body and the cover body, and is connected with the output end of an upper electric heating pipe control circuit of an electric control device in the machine body. The invention solves the technical problem of insufficient heating for the upper part of bread and the technical problem of safely transmitting power to the upper electric heating pipe arranged in the cover body and provides a safe power transmission connecting structure for a high-power electric device arranged in a split body hinged with a main body. The household bread maker provided by the invention is convenient, safe and reliable to operate and can be used for making bread with uniform fineness, thin skin and better taste and color.

Description

technical field [0001] The invention relates to a bread machine suitable for home use Background technique [0002] Household bread machines can automatically complete operations such as dough mixing, fermentation and baking. The heat source design of existing household bread machines generally adopts a single electric heating tube structure. The electric heating tube surrounds the lower part of the bread barrel and is installed on the inner wall of the baking chamber. The bread produced has uneven color, thick skin, and bad taste. The main reasons are The reason is that the upper part of the bread is relatively underheated. This is because the upper part of the bread is far away from the electric heating tube. The heat reflection of the bread barrel is too strong, and the metal cover lining on the top of the bread barrel for reflecting heat radiation is far away from the electric heating tube, and there is a perspective window in the middle, so the heat reflection is weak....

Problems solved by technology

The heat source design of existing household bread machines generally adopts a single electric heating tube structure. The electric heating tube surrounds the lower part of the bread barrel and is installed on the inner wall of the baking chamber. The bread produced has uneven color, thick skin, and bad taste. The main reasons are The reason is that the upper part of the bread is relatively underheated. This is because the upper part of the bread is far away from the electric heating tube. The heat reflection of the bread bucket is too strong, and the metal cover lining on the top of the bread bucket for reflecting heat radiation is far away from the electric heating tube, and there is a perspective window in the middle, so the heat reflection is weak

[0003] In view of the above problems, Chinese Patent Publication No. CN 107864 C discloses a bread machine upper cover structure, which is characterized in that a porous metal reflector is added below the see-through window of the cover body, which to a certain extent compensates for the heat lost due to the setting of the see-through window. Reflection, thereafter, Chinese Patent Publication No. CN2257692Y discloses a front-opening double electric heating tube bread machine. Its disadvantage is that the bread bucket cannot be taken out according to normal operation, because the bread bucket needs to be rotated vigorously and then lifted up to be taken out, and the upper part of the baking chamber is closed in the front-opening door structure, so there is no way to leave enough space above the bread bucket. space

In view of this situation, Chinese Patent Publication Nos. CN 201085513Y and CN 201664219 U have successively disclosed a bread machine with double electric heating tubes with the top open. The upper part and the lower part are fixed on the inner wall of the baking chamber, which has the advantage of solving the problem that the bread bucket cannot be taken out, and shortening the distance between the electric heating tube, the upper part of the bread and the lid lining, and improving the heating condition of the upper part of the bread to a certain extent. The disadvantage is that it is still not enough to compensate for the relative lack of heating of the upper part of the bread, because for the sake of not hindering the removal of the bread bucket and safety considerations, the upper electric heating pipe cannot be close to the mouth of the bread bucket, let alone placed on the mouth of the bucket; In addition, two electric heating tubes are arranged around the middle and lower part of the baking chamber, which is inconvenient for cleaning work, especially when cleaning the sundries below, it is easy to be scalded by the electric heating tubes above

The latest solution is the upper-opening single electric heating tube bread machine disclosed in Chinese Patent Publication No. CN101601548 B. The disadvantage of the set of electric heating tube control devices is that it still cannot solve the problem of insufficient heating of the upper part of the bread. Compared with the double electric heating tube bread machine, there is no progress in improving the heating of the upper part of the bread. The problem of burns is more prominent
