Automatic temperature control electric heating and gas heating dual-purpose baking oven

Abstract

The invention relates to the technical field of baking equipment, and particularly discloses an automatic temperature control electric heating and gas heating dual-purpose baking oven which comprisesan oven body, a combustion fire tube is installed in a combustion cavity of the oven body, and a latticed fire outlet is formed in the combustion fire tube; the combustion fire tube is connected witha gas pipeline and an air pipeline through a gas mixing pipe; a flue is arranged behind the oven body, and a flue gas adjusting device is arranged above the flue; and electric heating pipes are arranged below a baking plate and above and below the gridiron. Food can be baked in an electric heating mode and a fuel gas mode, and baking modes are diversified. The combustion fire tube adopts the latticed fire outlet, the fire outlet is uniform in fire outlet, energy is saved, combustion is more sufficient, and the stability of the baking temperature is guaranteed; the flue gas adjusting device isarranged, and the exhaust amount of flue gas is flexibly adjusted according to the baking process to achieve the purpose of adjusting the temperature in the oven; and a temperature control box is arranged, so that a user can conveniently observe the baking temperature in the oven, and convenience is provided for operation of the user.

Description

technical field [0001] The invention relates to the technical field of baking equipment, in particular to an electric heating and gas dual-purpose baking oven with automatic temperature control. Background technique [0002] There are three main heating methods for ovens on the market: [0003] 1. Traditional coal is used as fuel to bake food, but coal resources are non-renewable resources and the smoke generated by coal combustion causes serious air pollution. Therefore, baking with heat generated by burning coal is gradually expected in the market. cold. [0004] 2. The electric heating tube is used to heat the air and bake the food. The electric heating tube is heated by electric energy, which belongs to clean energy. However, the power consumption is too large, and the long-term continuous baking has too high requirements for the design of the electrical circuit. , electric heating can be used as a backup solution. [0005] 3. Using natural gas or liquefied petroleum ...

Problems solved by technology

[0005] 3. Using natural gas or liquefied petroleum gas as fuel, due to the stable supply of gas, high heat, and little air pollution, therefore, ovens using gas as baking fuel have become the mainstream of the market. However, the existing gas oven functions It is relatively simple, especially to control the baking temperature, which is generally achieved by controlling the switch of the gas pipeline based on experience, or by controlling the ratio of air and gas. The control time is not timely and the control accuracy is low, resulting in unstable baking temperature.
