Description

Technical Field

[0001] The utility model relates to the technical field of energy conservation and environmental protection, in particular to an environmentally friendly and energy-saving cooking gas stove. Background Art

[0002] The gas large pot stove is sturdy and durable, breaking the previous combustion method, allowing the flame to be transmitted to the surroundings in the furnace, with uniform firepower, energy saving and high efficiency; it has reasonable design, beautiful appearance and no pollution. Commercial kitchen equipment, large pot stoves, electromagnetic, gas large pot stoves are suitable for hotels, restaurants, enterprises and institutions, and are ideal equipment in the kitchen. Large pots with a diameter of more than 80 cm are usually used. They are mainly used in large canteens of schools, factories and other units for frying and roasting large pot dishes. At present, in the environment of energy conservation and emission reduction, secondary products such as energy-saving large pot stoves have been derived. The large pot stoves of commercial kitchen equipment currently on the market generally save energy by about 35%. Since traditional large pot stoves usually rely on fans to increase firepower, they are very noisy. The new energy-saving large pot stoves are not only energy-saving, but also do not require blowers. Energy saving, environmental protection and noiselessness have made this type of product quickly become a replacement product for traditional large pot stoves. However, the existing gas large pot stoves will produce a lot of oil smoke when working, which greatly affects the air quality and also has a certain impact on the user's health.

[0003] For example, a Chinese patent document discloses an energy-saving and environmentally friendly gas stove (Announcement No.: CN215523361U). Although this patent achieves the effect of discharging the oil smoke generated by the large stove body when it is working into the mixing box through the arrangement of the air pump, the air intake pipe and the suction plate, it achieves the effect of fully stirring and mixing the water and the exhaust gas through the arrangement of the motor and the stirring rod, and achieves the effect of evenly spraying the mixed water through the arrangement of the delivery pump, the delivery pipe and the nozzle, and achieves the effect of multiple purification and filtration of the water through the arrangement of the first filter and the second filter.

[0004] However, in actual use, since the oil smoke contains a large amount of dust particles and oil stains, these impurities and oil stains, after mixing with the water inside the mixing box, if they are directly extracted and used through a delivery pump, the delivery pump will easily be blocked after long-term use, and the particles and oil stains will be sprayed on the surface of the first filter through the nozzle, which will not only cause the first filter to be blocked and difficult to clean, but also block the exhaust gas, resulting in poor exhaust.

[0027] Example

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: an environmentally friendly and energy-saving large gas stove for cooking, comprising a stove body 1 and a filter box 2, a storage box 3 fixedly connected to the front of the filter box 2, a glass window being provided on the front of the storage box 3 to facilitate an operator to observe the remaining amount of cleaning liquid inside, a filling pipe 4 being fixedly connected to the upper surface of the storage box 3, a small submersible pump 5 being fixedly mounted on the inner bottom wall of the storage box 3, a delivery pipe 6 being fixedly connected to the water outlet end of the small submersible pump 5, one end of the delivery pipe 6 passing through and extending into the interior of the filter box 2, and one end of the delivery pipe 6 being fixedly connected to a corrugated telescopic pipe 7;

[0029] A movable flushing device is provided at one end of the bellows telescopic tube 7, and the movable flushing device includes a diverter tube 8 connected to the bellows telescopic tube 7, a plurality of flushing nozzles 81 connected to the diverter tube 8, a motor 86 fixedly connected to the filter box 2, and a reciprocating screw 87 fixedly connected to the output end of the motor 86. The plurality of flushing nozzles 81 are distributed in a linear array on the lower end surface of the diverter tube 8, and the reciprocating screw 87 is threadedly arranged on the diverter tube 8. The movable flushing device also includes a limiting component for limiting the diverter tube 8 to move only along the length direction of the reciprocating screw 87.

[0030] There are two guide rods 83 in the present application. The guide rods 83 and the guide blocks 82 cooperate with the diversion pipe 8 to drive the flushing nozzle 81 to move stably, and the telescopic characteristics of the corrugated telescopic tube 7 cooperate to perform mobile flushing.

[0031] A partition 84 is fixedly mounted on the inner wall of the filter box 2, and a stainless steel wire mesh filter 85 is fixedly mounted on the inner wall of the partition 84. A motor 86 is fixedly installed on the front of the filter box 2, and a reciprocating screw 87 is fixedly mounted on the output shaft of the motor 86 through a coupling. One end of the reciprocating screw 87 passes through and extends to the interior of the filter box 2.

[0032] Stove smoke contains various impurities, including large particles. For example, when frying or stir-frying food, food debris and grease particles may be emitted along with the smoke. The mesh of the stainless steel wire mesh filter 85 can effectively intercept these large particles, preventing them from drifting into the indoor air with the smoke. The stainless steel wire mesh filter 85 has excellent high-temperature resistance, can operate stably in high-temperature environments, is easy to clean, and can be reused.

[0033] The outer surface of one end of the reciprocating screw 87 is installed with the rear inner wall of the filter box 2 through a bearing. The outer surface of the reciprocating screw 87 is threadedly connected with a threaded block 88. The lower surface of the threaded block 88 is fixedly connected to the upper surface of the diverter pipe 8. The lower surface of the filter box 2 is fixedly connected with a sewage pipe 89. The reciprocating rotation of the reciprocating screw 87 drives the diverter pipe 8 to move back and forth through the threaded block 88.

[0034] An electromagnetic valve 810 is fixedly installed on the outer surface of the sewage pipe 89, an activated carbon filter frame 811 is movably inserted into the front of the filter box 2, an exhaust pipe 812 is fixedly connected to the upper surface of the filter box 2, and support legs 813 distributed in a rectangular array are fixedly connected to the lower surface of the filter box 2.

[0035] An activated carbon filter is installed in the activated carbon filter frame 811. When the stove is in use, it produces harmful gases such as carbon monoxide and nitrogen oxides. Carbon monoxide is a colorless, odorless, and non-irritating toxic gas. It binds to hemoglobin in human blood, causing it to lose its oxygen-carrying capacity, leading to hypoxia in human tissues. Nitrogen oxides can irritate the respiratory tract, causing symptoms such as coughing and wheezing. Long-term exposure may also lead to respiratory diseases. The activated carbon filter can absorb these harmful gases into its developed pore structure through physical adsorption, thereby reducing the amount of these harmful gases entering the indoor air.

[0036] One end of the plurality of support legs 813 is fixedly connected to the upper surface of the stove body 1 , and one side surface of the filter box 2 is fixedly connected to an air intake pipe 814 , and one end of the air intake pipe 814 is fixedly connected to a smoke hood 815 .

[0037] An exhaust fan is provided inside the smoke hood 815 to facilitate the extraction of generated smoke into the filter box 2 through the air inlet pipe 814 for purification.

[0038] Through the mobile flushing device, the dust particles adsorbed on the stainless steel wire mesh filter 85 are flushed by the reciprocating movement of the flushing nozzle 81, thereby ensuring that the stainless steel wire mesh filter 85 can stably intercept the dust particles in the flue gas to avoid blockage, and the activated carbon filter in the activated carbon filter frame 811 can adsorb the oil gas and odor in the flue gas, which not only improves the working environment of the operator, but also is conducive to energy saving and environmental protection.

[0039] The working process of this utility model:

[0040] Step 1: The exhaust fan in the smoke hood 815 transports the smoke through the air inlet pipe 814 to the interior of the filter box 2. The dust particles in the smoke are intercepted and filtered by the stainless steel wire mesh filter 85, causing them to fall to the bottom of the filter box 2. The filtered smoke passes through the activated carbon filter again to absorb the oil, gas and odor. Finally, the purified gas is discharged through the exhaust pipe 812.

[0041] Step 2: When it is necessary to clean the particles adsorbed on the stainless steel wire mesh filter 85, the operator mixes the cleaning liquid with water and adds it to the storage tank 3 through the filling pipe 4. The small submersible pump 5 is started to deliver the cleaning liquid to the bellows through the delivery pipe 6. Finally, the cleaning liquid is sprayed out through the flushing nozzle 81 under the diverter pipe 8, thereby backwashing the stainless steel wire mesh filter 85.

[0042] Step three, simultaneously start the motor 86 to drive the reciprocating screw 87 to rotate, and the rotation of the reciprocating screw 87 drives the diverter pipe 8 to move back and forth through the threaded block 88, thereby driving the flushing nozzle 81 to fully flush the stainless steel wire mesh filter 85 back and forth. The flushed particulate impurities are accumulated at the bottom of the filter box 2 along with the cleaning liquid, and the sewage can be discharged by opening the solenoid valve 810 of the drain pipe 89. By regularly and automatically cleaning the stainless steel wire mesh filter 85, it is ensured that the particulate impurities in the flue gas are effectively intercepted and filtered.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
