Description

Technical Field

[0001] The utility model relates to the field of commercial bun steaming furnaces, in particular to a liquid fuel bun steaming furnace. Background Art

[0002] Most commercial stoves use liquefied gas fuel, such as gas cylinders, which are widely used in schools, military units, restaurants, hotels and other multi-person stove occasions. This traditional liquefied gas has problems such as low calorific value, high cost, low flash point, flammability and explosion, and great safety risks. Due to the great safety risks of liquefied gas fuel, commercial stove fuel has begun to turn to liquid fuel (coal-based liquid fuel), a safe fuel with a relatively high flash point. Commercial stoves that use liquid fuel are mainly electric fuel injection stoves, and the main application areas are commercial fierce fire stoves, a series of Chinese food frying stoves, and large pot stoves. They are also used in other kitchen stoves such as steamers, stew barrels, cooking stoves, clay pot stoves, etc. and heaters. The disadvantages of electric spray stoves are as follows: 1. Due to the use of electric spray, high pressure is required for atomization to make the liquid fuel meet the combustion conditions. It is mostly used in high-temperature and high-fire stir-frying scenarios. The nozzle cannot atomize under high-pressure conditions, so it is not possible to slow cook or stir-fry over low pressure and low heat. It is not suitable for long-term heat preservation in steamed bun ovens; 2. And it requires an external 220V power supply, which means that the steamed bun oven must be connected to an external wire before it can be used.

[0003] The current steamed bun ovens also use electric heating. The heat generated by the electric heating method is low. Although it can be used for low-temperature insulation mode, it is not suitable for high-temperature rapid steaming in medium and large steamed bun ovens. It also requires an external power supply and consumes a lot of energy.

[0004] Our company has developed a multi-stage split energy-saving combustion device for liquid fuel, namely, a liquid fuel ion combustion device. This device uses liquid fuel as fuel, and changes the original open combustion mode of the electric fuel injection stove into a closed multi-stage combustion mode. It does not need to be atomized by a high-pressure atomizing nozzle, which greatly reduces the heat energy loss. Compared with the electric fuel injection stove, the heat utilization rate is nearly doubled, and the energy consumption such as oil and electricity is only half of the original. It can be used with a mobile power supply, and it is safer, independent, and has a wide range of applications.

[0005] Therefore, it is urgent to carry out structural design of the existing bun steaming furnace so that it can use liquid fuel as energy and work in low fire, medium fire and high fire modes, thereby greatly improving its working efficiency and reducing energy consumption. Utility Model Content

The utility model adopts the liquid fuel ion combustion device 7 developed by our company. The device has low energy consumption and realizes the vaporization of liquid fuel through the heat energy generated by the combustion of the ion combustion body 72. The continuous combustion of liquid fuel can be achieved without high-pressure atomization. The large, medium and small firepower can be adjusted at will according to needs. Moreover, the steamed bun oven only needs to be equipped with a mobile power box 13 for use, and no external power supply is required, which greatly increases the flexibility of the use scenarios of the steamed bun oven.

[0028] The liquid fuel ion combustion device 7 adopts closed heating. After the liquid fuel is burned in multiple stages by the ion combustion body 72, it enters the closed combustion tube 71 for full combustion, and the heat is ejected from the front end of the combustion tube 71 for heating. In order to make the utility model better applicable to the steamer, a water combustion box 8 is designed at the bottom of the steam box 4. The design of the water combustion box 8 is convenient for the installation and use of the fuel ion combustion device 7. The water combustion box 8 is a box structure with an open upper end, which is convenient for the water combustion box 8 to be connected with the inside of the steam box 4. After the connection, water can directly enter the water combustion box 8, and the water can be directly heated by the heating tube 81. The water combustion box 8 is horizontally provided with a heating tube 81, the front end of the heating tube 81 is closed, and the rear end is fixedly connected to the side of the water combustion box 8.
