Description

Sewage management system for camping car {SEWAGE MANAGEMENT SYSTEM FOR CAMPING CAR}

The present invention relates to a sewage management system for campers, and more particularly, to a sewage management system compatible with various types of campers.

A camping car relates to a vehicle equipped with various living facilities, and is widely used in the form of a travel trailer that is attached to a pick-up truck or the like with living facilities integrally installed at the rear of the vehicle. Since such vehicles are mainly called RVs (Recreational Vehicles) in North America, and travel trailers are also called caravans, vehicles equipped with living facilities such as RVs and caravans are defined as campers and described below for clearer explanation.

Camping cars are largely divided into American (North American) and European models. At this time, the difference between the interior of the American camper and the European camper is clearly distinguished, as well as the method of handling sewage and dirt inside. The American camper has a black water tank and a gray water tank installed inside, so that the sewage from the toilet is accommodated in the black water tank, and the sewage generated through showering or washing dishes is stored in the gray water tank. accommodated in the tank. In addition, the European camper has a service door installed on the outside and is configured to be transported by the user using a carrier-sized movable garbage tank (hereinafter referred to as a 'cassette') to treat a small amount of sewage and dirt at home or in an outdoor toilet. do.

US Patent Registration No. 6957668 and US Patent Registration No. 6352088 disclose a sewage management system for an American model camping car. At this time, in US Patent Registration No. 6957668, as shown in FIG. 1, a hose 3 is provided to connect the RV 1 to the dumping connector 2, which is the inlet of the underground tank. And US Patent Registration No. 6352088 discloses a system for managing the discharge of sewage from a black water tank and a gray water tank installed inside an RV, as shown in FIG. 2 .

In this way, the American camper is provided with a separate dump station to discharge sewage from the black water tank installed inside the RV, while the European camper can be transported by the user through a cassette to discharge sewage. That is, there is a limit in that an American camping car can be utilized only when an infrastructure for a dump station is built. In addition, as campers may have problems due to sewage discharged by users without permission, a separate system compatible with various types of campers including American campers and European campers is required.

In the drawing, the sewage storage tank 100 is formed in a form buried underground, and the first inlet 110 and the second inlet 120 are installed on the bottom surface of the housing 500, but, This is for a clearer description, and a shelf may be installed inside the housing 500 so that the first inlet 110 or the second inlet 120 may be installed. The first inlet 110, which is an inlet for discharging waste water of the cassette 40, may be disposed closer to the opening and closing door 510 than the second inlet 120, which means that the cassette 40 is a carrier type As a result, since the user mainly rotates and drains the device by hand, it can lead to the advantage of improving convenience.

The supply module 210 extends from the fresh water storage tank 200 to a hose and is disposed on the front side of the housing 500, or may be disposed adjacent to the first inlet 110 or the second inlet 120. there is. Further, the supply module 210 may provide washing water by supplying fresh water to the cassette 40 or the black water tank 21 , and may also provide white water to the white water tank 23 .

Referring to FIG. 6, the sewage management system 10 according to the present invention further includes a connection pipe 130 connecting the first inlet 110 and the second inlet 120 to the sewage storage tank 100. can do. At this time, the connection pipe 130 may include a first pipe 131 having one end connected to the first inlet 110 and a second pipe 132 having one end connected to the second inlet 120. . At this time, the first pipe 131 and the second pipe 132 are formed as different pipelines and connected to the sewage storage tank 100, or the connection pipe 130 is connected to the first pipe 131 and the second pipe 132. A 'Y'-shaped conduit may be formed by further including a third pipe 133 having one end connected to the other end of the two pipes 132 and the other end connected to the sewage storage tank 100. Accordingly, the sewage management system 10 according to the present invention can prevent the odor generated from the sewage stored in the sewage storage tank 100 from being discharged to the outside along the connection pipe 130 .

The sewage management system 10 according to the present invention includes a first valve 141 installed on the first pipe 131 to open and close the pipeline and a second valve installed on the second pipe 132 to open and close the pipeline ( 142) may be further included. In addition, although not shown separately, a separate valve may be installed in the third pipe 133 to open and close the conduit. At this time, the first valve 141 or the second valve 142 may be a combination of various valves such as a check valve and a solenoid valve. More preferably, the first valve 141 or the second valve 142 is a reverse flow A prevention valve and a valve that can be opened and closed from the outside through electrical control may be included. In addition, the interface 400 can visualize and output a window for selecting the type of camper vehicle, and when the user selects the type of vehicle, the corresponding vehicle type among the first valve 141 or the second valve 142 is displayed. It can be controlled to open what fits into. For example, when the user selects an American model camper, the second valve 142 can be opened, and the user inserts the connection hose 30 connected to the black water tank 21 of the camper 20 to the second inlet. 120, the sewage may be discharged to the sewage storage tank 100 through the second pipe 132 and the third pipe 133. As another example, when the user selects a European model camper, the first valve 141 may be opened, and the user discharges sewage to the first inlet 110 through the outlet 41 of the cassette 40. can make it At this time, the first inlet 110 may be a hole opened to the outside, and may be a hole having a narrower width toward the lower side. In addition, a stopper is disposed at the first inlet 110 so that the inlet 110 may be sealed through the stopper when not in use.
