Description

Baking oven

Technical Field

The utility model relates to the technical field of household appliances, in particular to an oven.

Background

The existing oven is mostly provided with heating pipes from top to bottom, usually, the upper heating pipe is directly arranged in the cavity of the inner container, and the lower heating pipe is usually arranged outside the bottom of the inner container in order to avoid being polluted by food residue, oil stain and the like. This just brings a problem to the oven that has the wind channel at the back, for the cotton piece of heat preservation in order to prevent the back is blown out the oven by the wind in the wind channel, increases the wind channel backplate at the back of inner bag usually, and the cotton clamp of heat preservation is located between inner bag and the wind channel backplate to separate heat preservation cotton and wind channel, the wind channel backplate is when hiding the heat preservation cotton, also hides lower heating pipe. This leads to the lower heating pipe very inconvenient when after-sale maintenance and change, usually needs two at least after-sale personnel cooperations, falls the oven, just can take out the lower heating pipe and change after dismantling the bottom plate, backplate, bottom wind channel baffle, bottom heat preservation cotton, the support frame of casing in proper order, in addition still need prevent to lead to the risk of the surface scratch to take place because of falling the oven, and whole process is very complicated, and is very unfriendly to after-sale personnel, and the after-sale cost of lower heating pipe is very high.

In order to improve the convenience of the disassembly of the lower heating pipe, a notch is added on a lower front beam of the oven, the size of the notch is slightly larger than the size of the lower heating pipe, a quick-change bracket of the lower heating pipe is added to hook the lower heating pipe, and the bracket is fixed at the opening position of the lower front beam. When changing, after-sale personnel need pull down the backplate of oven earlier, unplug the power supply line of being connected with the terminal of lower heating pipe, then wind the oven openly, pull down the door body and fix decorative board and the quick change support on the front-axle beam down, then pull out lower heating pipe through the quick change support, change or after the maintenance is accomplished, reuse quick change support and push into the oven bottom with lower heating pipe, accomplish behind the installation of other spare parts of contrary preface. This scheme is when the heating pipe ann that will change returns inner bag bottom, when needing to insert the heating pipe terminal back to relevant position, and the position of air duct backplate can't be seen to the personnel after sale, is in the state of blind insertion, and the degree of difficulty coefficient is great. The heat preservation cotton has certain toughness, can prevent that the heating pipe from passing the heat preservation cotton, and the structure of heating pipe itself has certain elasticity, therefore is harder when returning the heating pipe installation fixed position, needs certain skill, still can lead to the heating pipe to warp under the extreme condition.
