Abstract
Description
Technical Field
[0001] The utility model relates to the field of kitchenware, in particular to an all-in-one oil fume purification machine with gas leakage protection. Background Art
[0002] In daily cooking, cooking methods such as steaming and stewing are often used. This method takes a long time. During this process, you need to stay in the kitchen to prevent water from overflowing and causing the flame to go out, thereby causing gas leakage. In summer, the steaming and stewing processes will continue to emit heat, which is extremely uncomfortable for people. Therefore, it is particularly important to have gas leakage protection. Existing kitchens generally install gas sensors, but most of the gas sensors are installed near the ceiling. When gas is detected, a large amount of gas has already leaked, posing a safety hazard.

[0020] like Figure 1 to Figure 3As shown, the oil fume purification integrated machine with gas leakage protection provided by the present embodiment comprises an oil fume machine body 1 and an air duct 2 arranged on the oil fume machine body 1, and the air duct 2 is sequentially installed with a steel wire filter, an evenly distributed sealing plate, a deodorizing device, and an electrostatic adsorption device along the flow direction of the wind. After the oil fume passes through the steel wire filter, the evenly distributed sealing plate, the deodorizing device, and the electrostatic adsorption device in sequence, the purification effect can be guaranteed. The air duct 2 is U-shaped, and the air near end of the air duct 2 is provided with a straight exhaust pipe 7 connected to the air outlet end of the air duct 2. The straight exhaust pipe 7 can directly suck the gas into the flue, so as to avoid the gas being affected by electric sparks when passing through the electrostatic adsorption device and the deodorizing device and causing safety accidents. Both ends of the straight exhaust pipe 7 are installed with baffle valves 8, which are usually in a closed state and open when gas leaks to ensure the effect of oil fume purification; a circle of storage grooves 3 are processed around the ground of the range hood body 1, and a closing device 4 is installed in the storage groove 3. The closing device 4 includes an upper limit frame 41, a lower limit frame 42 and a protective cover 43. The cross-sections of the upper limit frame 41 and the lower limit frame 42 are L-shaped, and the protective cover 43 is accordion-shaped and installed between the upper limit frame 41 and the lower limit frame 42. The two ends of the protective cover 43 are connected to the upper limit frame 41 and the lower limit frame 42 respectively. 43 is woven by asbestos mesh, which has the characteristics of high temperature resistance. After the lower limit frame 42 falls out, the protective cover 43 can be driven to wrap the stove. The lower limit frame 42 is suspended and the distance from the stove surface is 2 to 5 cm. This distance allows fresh air to quickly enter the protective cover 43 to dilute the gas to avoid explosion caused by excessive gas concentration. Under the suction of the fan of the range hood body 1, the air in the protective cover 43 will be quickly drained to produce a negative pressure state. At this time, the protective cover 43 made of asbestos mesh can slowly provide a certain amount of fresh air to ensure the stability of the protective cover 43 structure and avoid deformation of the protective cover 43. , affecting the suction of leaked gas, a gas detector 5 is installed on the range hood body 1 inside the storage groove 3, and the gas detector 5 is used to detect whether the gas is leaking. An electromagnetic baffle 6 for locking the lower limit frame 42 is installed in the storage groove 3, and the gas detector 5 is connected to the controller of the electromagnetic baffle 6. The gas detector 5 is connected to the main gas valve, and the purpose is to close the main gas valve when a gas leak is detected, thereby controlling the scale of the gas leak. The gas detector 5 can be switched to a manual monitoring mode. The manual monitoring mode can be used for monitoring during a long steaming or boiling process when the operator can temporarily leave the kitchen.
[0021] An audible and visual alarm 9 is installed on the outer wall of the range hood body 1. The audible and visual alarm 9 is used to sound an alarm when a gas leak is detected, so as to remind the user to check and handle the problem.
[0022] The method of using the utility model is:
[0023] In normal use, the range hood body 1 has the same functions as a traditional range hood; during a long steaming or boiling process, in order to allow the operator to temporarily leave the kitchen, the operator starts the gas detector 5 on the range hood body 1. When the gas detector 5 works, if the water or soup in the pot overflows and causes the stove to go out, the gas on the stove will continue to be released, resulting in gas leakage. When the gas detector 5 detects a gas leakage, the electromagnetic baffle 6 is controlled to open, and the lower limit frame 42 drives the protective cover 43 to unfold under the action of its own gravity and covers the stove. Figure 4 As shown, the stove is in a relatively closed environment at this time, and the baffle valve 8 on the straight exhaust pipe 7 is opened. The fan on the range hood body 1 directly sucks the leaked gas into the flue through the straight exhaust pipe 7. The air in the flue is mainly purified gas after combustion, and the oxygen content is not high, which will not cause gas explosion. At the same time, the fan will continuously pump air to dilute the gas to avoid explosion hazards caused by excessive gas concentration. During this process, the gas detector 5 sends a gas leakage signal, the main gas valve is closed, and the sound and light alarm 9 works to remind the gas leakage. After the operator returns to the kitchen, he closes the gas valve on the stove body, then lifts the lower limit frame 42, folds the protective cover 43 and puts it back into the receiving tank 3 again, and then turns off the gas detector 5. At this time, the baffle valve 8 is closed, and the operator continues to cook after eliminating other faults.
[0024] The main application scenario of the solution disclosed in this patent is the operation when a single person is cooking. During the cooking process, it can prevent gas leakage caused by accidental extinguishing of the gas hood when the operator leaves the kitchen for a short time, which can effectively improve cooking safety.
[0025] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and the utility model concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
