Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification devices, and more specifically to an intelligent fire extinguishing device for oil fume purification equipment. Background Art

[0002] Kitchen fumes have always been a problem when cooking. In order to solve the various problems of dealing with fumes, the existing range hoods have integrated various functions, such as fume purification. Through the integrated purification system, the collected fumes are purified to meet the emission standards. Especially for large catering places, such as school canteens, employee canteens, restaurants and large catering distribution companies, this kind of range hood with purification function is widely welcomed. However, the fume purification device often encounters the following problems during use, which are difficult to solve: 1. All current fume purification equipment is very easy to cause fires and does not have a fire extinguishing function. 2. The existing method is to add a water tank to the fume purification equipment. Although it can reduce the risk of fire, it does not have a fire extinguishing function and is easy to cause the purifier to enter water and not work. 3. Affected by the internal structure of the purifier, the use of dry powder fire extinguishers or water-based fire extinguishers cannot effectively extinguish the fire of the fume purifier. In view of the above problems, the inventors have proposed an intelligent fire extinguishing device for oil fume purification equipment. By adding a special box outside the oil fume purification equipment to store the liquid carbon dioxide fire extinguishing device, when a fire occurs, the oil fume purification equipment can be effectively extinguished by the liquid carbon dioxide fire extinguishing device, thereby improving fire safety.

[0003] In order to solve the problem that the traditional oil fume purification equipment is not equipped with a fire extinguishing device, which leads to the inability to extinguish the fire in time when it occurs, and the kitchen has a great fire safety hazard, a Chinese patent (authorization announcement number: CN218583223U) discloses an oil fume purification system with automatic cleaning and automatic fire extinguishing functions. The utility model includes a chassis body, an electrostatic oil fume purifier is arranged in the chassis body, an exhaust fan is arranged in the exhaust area, and a deodorizing plate is arranged vertically between the electrostatic oil fume purifier and the exhaust fan; the chassis body is also provided with an automatic cleaning system and an automatic fire extinguishing system; the automatic cleaning system includes a water storage tank, a detergent storage tank, and a mixed liquid tank, and a cleaning spray pipe is arranged horizontally at the end of the mixed liquid tank; the automatic fire extinguishing system includes a dry powder storage tank, and a fire extinguishing spray pipe is arranged under the dry powder storage tank. The utility model has a simple structure and is easy to install. It adds the function of oil fume purification to the traditional range hood, and integrates the automatic cleaning and automatic fire extinguishing functions on this basis, which can solve the safety hazard of kitchen fire.

[0004] This solution still has some shortcomings in application. When a fire occurs, the smoke and dust are very large and the working temperature is very high, which can easily burn the fire extinguishing device, including alarms, sensors and switches. At the same time, the location of the fire is not certain, it may be at the air inlet or at the air outlet. Fire extinguishing devices need to be installed at these two key locations to improve the safety factor. Therefore, it is necessary to improve the structure of the fire extinguishing device of the oil fume purification equipment so that it can carry out timely and effective fire extinguishing when a fire occurs, and at the same time, it can achieve full coverage as much as possible.
