JPH0424335A - Washing and sterilizing system around drainage trap - Google Patents

Abstract

PURPOSE:To increase the sterilizing effect and to prevent the generation of bad smell by inserting a balloon which expands and contracts provided at the tip of an air feeding and exhausting tube to the lower side of a water drainage to block the exhaust pipe way, pouring a sterilizer, and then leaving it for a specific time. CONSTITUTION:A balloon 22 which expands and contracts is provided at the tip of an air feeding and exhausting tube 20. Then the balloon 22 is inserted in a drain pipe 8 connected to an exhaust port 2 of a sink up to a specific position, and the air is fed by a pump 19 to expand the balloon 22 so as to block the pipe way. Furthermore, a sterilizer is poured, and it is left for a specific time to increase the sterilizing effect. Consequently, bacteria and a bad smell resulting from the bacteria can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Applications Piping systems that consume hot water are generally widespread. This includes the drainage trap system.

BACKGROUND OF THE INVENTION Drain traps are installed in drains to prevent drainage-related odors from flowing back into the drain.

Additionally, the inside of the pipes is cleaned using brushes and the like.

Problems that the invention aims to solve In areas where hot water is used and the water is connected to a drain pipe, such as kitchens and wash basins, drain traps are installed to prevent bad odors from flowing back from the drain pipe. ing. This is done by setting up a U-shaped or loop-shaped piping a little lower than the drain, where water is always collected, allowing water to pass through, but stopping gas from coming in from below. Therefore, bad odors in the drainage pipe system can be prevented here, but the only part of the puddle that prevents bad odors is the part with a slight drop where the wastewater flows backwards, and conversely bacteria can grow in this part. It is also a cause of bad odor. For this reason, even if you try to clean and sterilize the area around the drain trap, including the drain outlet, by injecting a cleaning sterilizing solution or a disinfecting sterilizing solution, it will only clean and sterilize a small part of the backflow head part of the drain trap. Since the liquid does not accumulate and the sterilizing liquid that exceeds the backflow difference of the trap flows away into the drain pipe, it is usually impossible to completely sterilize the area around the drain trap and eliminate the source of the bad odor. Therefore, when a bad odor occurs from around the drain trap, a disinfectant and sterilizing solution is poured to reduce the source of the bad odor and temporarily eliminate the bad odor, but over time, the bacteria that causes the bad odor will propagate and generate the bad odor again.
It's become a repeated game of cat and mouse.

Means for Solving the Problem The drain trap installed at the drain outlet cannot store more liquid than the head of the backflow device installed to cut off the gas contained in the drain trap itself. Therefore, it is impossible to completely sterilize the entire drainage system by filling it with a sterilizing disinfectant and retaining it for a certain period of time.

This invention enables this part to be filled with a sterilizing and disinfecting solution, thereby making the sterilizing and disinfecting effect effective.

How this invention works: A balloon is sent to a position below the drain trap at the drain outlet, air is sent through the balloon through an air tube and an air pump is used to inflate the balloon, close the drain pipe, and then close the drain trap system. By injecting disinfectant and sterilizing solution until the entire area is filled, and leaving it for a certain period of time, the entire drain trap system above the balloon is completely disinfected and sterilized, and the source of the bad odor is completely removed from the trap system. I can.

Example 1, Figure 1, Figure 2, and Figure 3 show Example 1 and correspond to the sink drainage system. Figure 1: The sink opening (2) is connected to the sink surface (1).

(2) has a lower ice chamber (4) below this, and inside (4) there is a rising part (5), and below this there is a connecting part (7), which connects to the sewer pipe (8). (4) and (5)
There is a backflow cap (6) between the top and the wastewater that flows from the top passes through the garbage receptacle slot (3) and then into the drain (4).
and (6), passes between (5) and (6), exits to the drain pipe (8), and flows out into the drain system.

Therefore, even if a sterilizing disinfectant is injected into (2) in this state, (
Since the liquid only collects in the area between 4) and the rise (5), it is impossible to completely disinfect and sterilize the entire drain.

Therefore, from Fig. 1, we removed the dust cover (9), the garbage receptacle, the basket (3), and the backflow cap (6), and used a brush to remove the dirt from all of them beforehand, leaving them in the state shown in Fig. 3. Insert the drainage circuit shutoff device with the balloon (22), send and exhaust pump (19)
) is used as an air pump to send air into the balloon (22) through the tube (20), the balloon (23)
Since it will expand as shown in Figure 3, close the drain pipe as shown in (10). In this state, if you fill the pipe with sterilizing disinfectant from above to the liquid level shown in Figure 3 C, the entire drain pipe will be sterilized at the same time as it comes into contact with the sterilizing disinfectant.

After sterilization is completed, remove the pump (1) of the drainage circuit shutoff device.
9) is operated as an exhaust pump to remove the air in (22), take it out from the drain pipe, and add it to (2), (3), (6) (
Setting 9) will restore the original state.

Example 2 Figure 4 shows Example 2. There are two types of drains connected to washbasins, etc.: those with U-shaped piping and those with looped piping, but here we will talk about the easy-to-understand U-shaped drain trap.

Figure 4: Remove dirt from the inside of the drain trap piping using a brush, etc. Liquid can only accumulate in the pipe up to line F. Any more water will run down the drain. Washbasin (13) is connected to drain pipe (14) and drain trap (15) (16) by joint (]8)
It is connected to the drain pipe (17) and discharged to the outside.

As mentioned above, the liquid only accumulates in the drain trap up to the F line, so even if the sterilizing disinfectant is injected, the inner part (16) located higher than that will always be in contact with the sterilizing disinfectant. there is no. Therefore, a drain circuit closing device is inserted from the top, and the pump acts as an air pump to send air through the tube (20) to the balloon (22) and close the drain pipe (17). Furthermore, insert the tube (28) of the exhaust pump (27) in Figure 7 into the drain trap,
Control it so that its tip (29) is located at the top of the drain trap. Next, operate the exhaust pump and pump the sterilizing and disinfecting solution into the drain pipe until the liquid level reaches E while removing the air from the trap.The area from the balloon (22) to the E side will be filled with the sterilizing and disinfecting solution. When the predetermined sterilization time has elapsed, the sterilization is complete, so switch the pump (19) to the exhaust pump, shrink the balloon (22), and remove it from the pipe.

Effects of the Invention In order to sterilize and disinfect, it is necessary to immerse the product in contact with a sterilizing disinfectant solution for a predetermined period of time, but since drain traps do not have a cutoff function, it was previously impossible to completely sterilize them. According to the system of the present invention, it is possible to meet the conditions for sterilization and disinfection, and to remove bacteria and the bad odor caused by them from the drain trap system.
