Description

Technical Field

[0001] The utility model relates to the field of commercial rice steaming cabinets, in particular to a high-efficiency and energy-saving rice steaming cabinet. 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.

[0003] Electric heating can be used for steaming a small amount of rice, such as electric rice cookers. However, for places with a large amount of steam, such as some large enterprises, school canteens, and some rice food processing plants, the heat generated by electric heating cannot heat a large amount of rice at one time, and the energy consumption is relatively large. Therefore, places with a large demand for rice use steam cabinets to heat rice. A large amount of steam is produced by a steam generator and supplied to the steam cabinet through a steam pipe. Due to the large combustion volume of liquid fuel electric spray stoves, the volume of steam generators is very large. One steam generator can be used by multiple steaming cabinets, and the safest, energy-saving and environmentally friendly way to generate steam is to heat it through a liquid fuel electric spray stove. Liquid fuel is safe and environmentally friendly and is currently a commonly used heating stove on the market.

[0004] However, the liquid fuel electric spray stove has the following disadvantages: since the atomizing nozzle adopted by the electric spray method has a minimum atomizing pressure requirement, the liquid fuel electric spray stove must always carry out a large amount of high-pressure oil supply to ensure that the liquid fuel meets the atomizing combustion conditions. If the oil intake is adjusted too small, the atomizing nozzle cannot be atomized, resulting in the inability of the liquid fuel to burn. Therefore, the existing liquid fuel electric spray stove cannot be adjusted to a low-fire insulation mode. When the rice is cooked, it needs to be kept warm. If there are other steam equipment in the factory, a part of the steam can be distributed to other steam equipment through the steam pipeline for use, and a part of the steam is reserved for the rice steaming cabinet to keep warm. If there is no other steam equipment that needs to use steam, in order to save energy, the steam generator can only be turned off to stop the steam supply, and the slow steaming and insulation mode cannot be provided for the rice. Moreover, the rice steaming cabinet does not have an independent heating steam device, and needs to cooperate with other steam equipment to use steam through the steam pipeline, which is very inconvenient.

[0005] 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 it can be miniaturized to supply independent heating to the rice steaming cabinet. 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.

[0006] Therefore, it is urgent to carry out structural design of the existing rice steaming cabinet so that it can use liquid fuel as energy and can work in low fire, medium fire and high fire modes, thereby greatly improving its working efficiency and reducing energy consumption.

[0026] The utility model will be further described below: a high-efficiency energy-saving rice steaming cabinet, see Figures 1 to 6, comprising a cabinet 1, wherein a rice steaming box 2 and a heating box 3 are arranged in the cabinet 1, wherein the rice steaming box 2 is located at the upper part of the cabinet 1, and the heating box 3 is located at the lower part of the cabinet 1, a steam generating chamber 4 is left between the bottom of the rice steaming box 2 and the heating, a heat preservation gap 41 is left between the rice steaming box 2 and the inner wall of the cabinet 1, and the heat preservation gap 41 is communicated with the steam generating chamber 4, a tube disc-shaped ion fire tube 9 is arranged in the steam generating chamber 4, a steam port 22 is opened at the bottom of the rice steaming box 2, a water combustion box 8 and a liquid fuel ion combustion device 7 are arranged on the top of the heating box 3, the upper end surface of the water combustion box 8 is communicated with the steam generating chamber 4, a heating tube 81 is horizontally arranged in the water combustion box 8, the ion fire tube 9 is communicated with the inside of the heating tube 81, the liquid fuel ion combustion device 7 is composed of a combustion tube 71, an ion combustion body 72 and a combustion body installation box 73, and the combustion tube 71 of the liquid fuel ion combustion device 7 is horizontally arranged in the heating tube 81 of the water combustion box 8. The utility model designs the structure of the rice steaming cabinet, designs a rice steaming box 2 on the upper part of the cabinet 1, and is used to put the tray support full of rice into the rice steaming box 2 to steam the rice immediately, designs a heating box 3 on the lower part of the cabinet 1 to install the heating equipment, and designs a water combustion box 8 for the liquid fuel ion combustion device 7 to install the liquid fuel ion combustion device 7, and reserves a steam generating chamber 4 for storing water between the rice cooking box and the heating box 3, and generates steam through the ion fire tube 9 in the steam generating chamber 4, and the generated steam enters the rice steaming box 2 from the steam port 22 to perform the steaming operation. A heat preservation gap 41 is reserved between the rice steaming box 2 and the cabinet 1, and a part of the steam generated by the steam generating chamber 4 will enter the heat preservation gap 41 to heat and keep the surrounding of the rice steaming box 2 warm. When the liquid fuel ion combustion device 7 turns on the low fire protection mode, the steam in the heat preservation gap 41 can have a good heat preservation effect on the rice steaming box 2.

[0027] Since an insulation gap 41 is reserved between the rice steaming box 2 and the cabinet 1, the installation structure of the rice steaming box 2 is specially designed. The rice steaming box 2 is in the shape of a box with an open front end. The front end of the rice steaming box 2 is fixed on the cabinet 1 opening of the cabinet 1, and the rear end of the rice steaming box 2 is suspended in the cabinet 1, thereby realizing the installation and fixation of the rice steaming box 2.

[0028] In order to improve the structural stability and load-bearing capacity of the rice steaming box 2 installation box, a flange structure 21 is provided on the end face of the front end of the rice steaming box 2.

[0029] The utility model adopts the liquid fuel ion combustion device 7 developed by our company. 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. The device has low energy consumption, and the heat energy generated by the combustion of the ion combustion body 72 realizes the vaporization of the liquid fuel. The continuous combustion of the liquid fuel can be achieved without high-pressure atomization, and the large, medium and small firepower can be adjusted at will according to needs. Moreover, the bun steamer 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 scenario of the rice steamer.

[0030] In order to make the utility model better applicable to the rice steaming cabinet, a water combustion box 8 is designed on the top of the heating box 3. The design of the water combustion box 8 is convenient for the installation and use of the fuel ion combustion device. The water combustion box 8 is a box structure with an open upper end, which is convenient for the water combustion box 8 to communicate with the inside of the steam box. After the connection, water can directly enter the water combustion box 8, and the water can be directly heated by the heating tube 81. A heating tube 81 is horizontally arranged in the water combustion box 8, and 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. A through hole communicating with the inside of the heating tube 81 is opened on the side of the water combustion box 8. The combustion tube 71 is inserted into the heating tube 81 through the through hole. The heating tube 81 is provided with a flange connection pipe, and the ion fire tube 9 is connected with the inside of the heating tube 81 through the flange connection pipe. In the utility model, the combustion tube 71 of the liquid fuel ion combustion device 7 is installed in the heating tube 81 of the water combustion box 8, and the heating tube 81 is heated by the combustion tube 71. After water is added to the steam generating chamber 4, since the heating tube 81 is placed in the water, part of the heat generated will be directly transferred to the water body to heat the water body, and the remaining heat will enter the steam generating chamber 4 through the ion fire tube 9 to heat the water body in the steam generating chamber 4. The exhaust gas after heat exchange is discharged from the ion silencer 10, and the steam generating chamber 4 generates steam for cooking and keeping warm in the rice steamer 2.

[0031] Through experiments, it was found that since the liquid fuel ion combustion device 7 adopts a closed combustion method, the high-temperature flue gas makes a lot of noise when it is directly ejected from the air outlet of the ion fire tube 9 after heat exchange. Therefore, an ion silencer 10 is designed at the bottom of the water combustion box 8. The air outlet of the ion fire tube 9 is connected to the air inlet of the ion silencer 10, and the exhaust gas noise is eliminated by using the ion silencer 10.

[0032] The combustion tube 71 is fixed on the fire outlet of the ion combustion body 72 to achieve the installation and fixation of the combustion tube 71. A hole is opened on the side of the water combustion box 8, and the combustion tube 71 is inserted into the water combustion box 8 from the hole. The opening connection is welded and sealed to prevent water leakage. The ion combustion body 72 is fixed on the combustion body mounting box 73 to achieve the installation and fixation of the ion combustion body 72. The combustion body mounting box 73 is fixed on the side of the water combustion box 8 to achieve the installation and fixation of the combustion body mounting box 73.

[0033] The cabinet 1 also includes a blower 11 for supplying air to the ion combustion body 72 and an oil pump 12 for supplying oil, and the blower 11 and the oil pump 12 are arranged on the combustion body installation box 73. A control box 15 and a portable power supply box 13 are arranged in the cabinet 1, and the blower 11 and the oil pump 12 are driven and controlled by the control box 15, and the power supply box 13 is electrically connected to the control box 15 through a wire.
