Abstract

[Problem] To provide a duct cleaning device and cleaning method that can reliably remove even solidified oil and grease stains without damaging the duct using a foamy cleaning agent, and that also allows for extremely easy cleaning and transportation. [Solution] The system includes an automatic foam gun 1 that generates a foamy cleaning agent Q. It also includes a cleaning hose 2 that sends the generated foamy cleaning agent Q into a duct P. A dispenser 3 connected to the end of the cleaning hose 2 releases the foamy cleaning agent Q. The system is configured to clean the inside of the duct P with the foamy cleaning agent Q released from the dispenser 3. [Selection Diagram] Figure 1

Description

This invention relates to a duct cleaning device and cleaning method, which are mainly suitable for cleaning exhaust ducts installed in barbecue tables and kitchens of barbecue restaurants. As a device for cleaning kitchen ducts, the pipe cleaning device described in Patent Document 1 has been proposed. This cleaning device consists of a flexible shaft 12, a cleaning unit 20, and a motor box 40. According to this cleaning device, the rotation of the brush 26 causes friction on the inner surface of the duct 62, and the resulting heat heats the cleaning solution 38, thereby increasing the cleaning effect of the cleaning solution 38. On the other hand, Patent Document 2 describes a pipe cleaning device for removing dirt such as oil, soot, and dust accumulated in exhaust ducts installed on barbecue tables in barbecue restaurants. This device is configured to scrape off firmly accumulated dirt such as oil, soot, and dust with a metal wire brush 6 while simultaneously sucking it up with a nozzle 5. Furthermore, Patent Document 3 describes a foam cleaning device that uses a micro-sized foam-like cleaning agent to clean drain pipes and the like. This foam cleaning device generates a micro-sized foam-like cleaning agent using the pressure of an inert gas, then fills the drain pipe with this foam-like cleaning agent using gas pressure, and cleans by reacting with deposits inside the pipe. Utility Model Registration No. 3117085 PublicationPatent No. 6402146Patent No. 5666054 This is an exploded perspective view showing one embodiment of the cleaning apparatus of the present invention.This is a side view of the main parts showing the usage state of the cleaning device of the present invention.(a) to (c) are side cross-sectional views of the main parts showing one embodiment of the cleaning method.(a) to (c) are side cross-sectional views of key parts showing other embodiments of the cleaning method.(a) to (c) are side cross-sectional views of key parts showing other embodiments of the cleaning method. The present invention is a cleaning device that cleans oil stains inside a duct P using a foamy cleaning agent Q. The main components of this invention include an automatic foam gun 1, a cleaning hose 2, and a discharger 3. Furthermore, an introduction body 4 is provided at the tip of the cleaning hose 2, and this introduction body 4 introduces the discharger 3, which is connected to the cleaning hose 2, into the duct P (see Figure 1). The device is configured to clean the inside of the duct P with the foamy cleaning agent Q released from the discharger 3 by the pressure of the automatic foam gun 1. The automatic foam gun 1 is a device that generates foamy cleaning agent Q, and commercially available car wash equipment can be used (see Figure 1). The illustrated example shows an automatic foam gun 1 in which diluted detergent is placed in the bottle 1A of the automatic foam gun 1, and foam is generated by pressurizing it with an electric pump. Other types, such as those connected to a high-pressure washer or those that are manually pressurized, can also be used. The cleaning hose 2 is a tubular member that delivers the foamy cleaning agent Q generated by the automatic foam gun 1 into the duct P (see Figure 1). Specifically, the base end of the cleaning hose 2 is connected to the discharge nozzle of the automatic foam gun 1, and the tip of the cleaning hose 2 is inserted into the duct P to deliver the foamy cleaning agent Q. The material of the cleaning hose 2 can be arbitrarily selected from flexible materials; for example, a rubber hose or a flexible hose may be used. The discharger 3 is a component connected to the end of the cleaning hose 2, and it discharges the foamy cleaning agent Q toward the inner surface of the duct P (see Figure 1). The illustrated discharger 3 comprises a connecting pipe 3A connected to the cleaning hose 2, a discharge pipe 3B fixed to the end of the connecting pipe 3A, and a discharge port 3C formed on the end of the discharge pipe 3B, which discharges the foamy cleaning agent Q in a 360° direction. The introduction body 4 is an elastic material such as urethane resin that holds the tip of the cleaning hose 2, introducing the tip of the cleaning hose 2 into the duct P (see Figure 1). This introduction body 4 also adheres closely to and slides against the inner surface of the duct P. In the illustrated example, two inlet units 4 are stacked on top of each other and fixed to the discharger 3 with retainers 5 and fasteners 6 positioned above and below (see Figure 2). When these inlet units 4 are connected to the end of the cleaning hose 2, the discharger 3 is held on the axial side of the duct P. Then, these inlet units 4 are inserted into the duct P, and the discharger 3, along with the cleaning hose 2, is introduced into the duct P (see Figure 2). At this time, the connection state of the cleaning hose 2, discharger 3, and inlet units 4 is not limited to the illustrated example. The introductio
