Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 Exhaust that can be buried in a building or in a building that has duct-type exhaust and smoke exhaust structures and that can be buried in buildings. This is the field of building maintenance.

[0002]

[Prior art]

 Cleaning of the inner surface of the exhaust and smoke exhaust ducts was performed by professionals using cleaning tools with brushes, cloths, etc. attached to rod-shaped tips such as steel and bamboo.

[0003]

[Problems to be solved by the invention]

 Anyone can easily clean the inside of the exhaust and smoke exhaust ducts, and a device that can automatically inject fire extinguishing liquid into the duct by detecting a temperature sensor in the event of a fire can be easily installed on new or existing buildings. So that it can be installed.

[0004]

[Means for Solving the Problems]

 A metal flexible hype is applied inside the smoke and exhaust ducts on the building, whether new or existing, and a round hole is provided in the hype to inject a cleaning solution during cleaning and a fire extinguishing solution during a fire. Smoke exhaust and ventilation by sealing the tip, providing a double-headed valve at the other end of the duct facility and connecting it to one end, and connecting the other end of the double-headed valve to a fire-extinguishing fluid storage tank for fire extinguishing. Duct cleaning and fire extinguishing are possible.

[0005]

[Operation]

 Dust and smoke components adhere to the interior of the exhaust and smoke exhaust ducts applied to the building, but especially the exhaust and ventilation ducts of food and beverage industry facilities fall off during cleaning because they contain oily components. Difficult, in this case, the liquid containing oil and fat components extracted from the orange crust as a cleaning liquid can be easily removed by spraying the liquid into the inside of the duct during cleaning. It works effectively at the next cleaning by covering the exhaust pipe.In this case, the exhaust pipe and the smoke exhaust duct in the building are curved and corners by providing countless round holes on the surface of the flexible pipe to intervene. The washing liquid can be sprayed evenly, and in the case of a duct fire, the duct fire can be suppressed by injecting high pressure digestive liquid into the hype.

[0006]

[Embodiment of the invention]

 A cleaning liquid and a fire extinguishing liquid that are installed in the exhaust and smoke exhaust duct facilities and that can easily clean the inner surface of the duct, in both new and existing buildings, on all surfaces in the duct. A flexible pipe made of metal is used as a means of jetting. A 0.8 mm round hole is formed on the outer surface of the pipe spirally in the direction of the extension of the pipe at 200 mm intervals at a diagonal angle of 60 degrees. One end is sealed and the other is fixed in an opening in the duct installation; the tip of the hype fixed in this opening is connected to a double-ended valve. Remove the cap, connect the connection hose of the cleaning device and inject the cleaning liquid, connect the other of the double-headed valve to the fire-extinguishing fluid accumulator cylinder with a fire-resistant hose, etc. The fire-extinguishing fluid of this accumulator cylinder is usually an electromagnetic valve. In the event of a fire, when a fire is detected by the temperature sensor on the duct, the solenoid valve of the fire extinguishing fluid accumulator opens via a signal line and the accumulated fire extinguishing fluid is injected into the duct via the flexible pipe. Structure.

[0007]

【Example】

 This device is a 200 mm 0.8 mm diameter round hole for jetting on the outer surface of the exhaust and smoke exhaust ducts shown in Figure 3-8 and the flexible pipe inside Figure 1-1. Connect the orange crust extraction and washing solution device in Fig. 1-2 and Fig. 4-14 to one of the double-headed valves in Fig. 4-11 and Fig. 3-7. When cleaning the inside of the duct, manually operate the washing solution injection operation In the panel shown in Fig. 4-13, the cleaning liquid is injected into the inside of the duct via the connection hose, and is injected into the deposit inside the duct from the injection round hole shown in Fig. 1-2 on the outer surface of the flexible pipe. The temperature sensor for detecting the temperature inside the exhaust and smoke exhaust ducts will be described based on an actual example of a fire extinguisher in the event of a fire inside the duct. At the opening of the duct facility, When the temperature sensor detects a high temperature in the event of a fire, the solenoid valve (Fig. 5-16) provided in the fire extinguishing fluid accumulator (Fig. 5-19) connected by the signal line operates, and the fire extinguishing fluid accumulator cylinder (Fig. 5-18) operates. The high pressure accumulated fire extinguishing fluid is connected to the other end of the connecting hose (Figure 5-17) and to the other of the double-headed valve (Figure 3-7) installed in the exhaust and smoke exhaust duct opening (Figure 3-6). The electromagnetic valve (Fig. 5-16) provided in the fire extinguishing fluid pressure accumulator is activated by the operation of the sensor Fig. 3-9, and the double-headed valve (Fig. 3-7) is automatically injected into the flexible pipe (Fig. 1-1). Exhaust and smoke exhaust duct cleaning equipment with a fire extinguishing function that has a washing and fire extinguishing function that is injected uniformly into the duct from the injection round holes in the pipes shown in Figures 1-2 and 2-2. It is.

[0008]

[Effect of the invention]

 Due to the structure inside the exhaust and smoke exhaust ducts applied to the building, such as duct connection and curved sections, such as brushing corners and wiping with a piece of cloth, deposits will remain.However, the flexible pipe of the present invention will be placed inside the duct. Spraying the cleaning fluid for spraying has a better cleaning effect.Similarly, the flexible pipe and fire-extinguishing fluid storage cylinder are connected to each other to detect the high temperature at the time of ignition by the temperature sensor applied to the opening and to detect the electromagnetic pressure of the fire-extinguishing fluid storage cylinder. By opening the valve, fire extinguishing fluid is injected into the flexible pipe at high pressure and injected through the injection hole in the pipe to prevent a large fire.
