Description

A smell smell removal device of drain pipe for washbowl}

The present invention relates to a malodor prevention device for a sink drain pipe, and more particularly, to provide an odor prevention device improved to prevent the odor coming up through the drain pipe while facilitating the drainage of water on the sink.

The wash basin is mainly fixed to one side wall inside the washroom or bathroom, and is provided to wash hands and face, and has a reservoir capable of receiving water discharged from the faucet.

A drain pipe having a drain valve for discharging the used water is connected to the bottom of the reservoir, and a means for preventing odor to prevent odor from rising is provided in the middle of the drain pipe.

Conventional malodor prevention device is shown in Figure 1,

The valve housing 4 is coupled to the bottom surface of the water storage tank 2 of the sink 1 provided at the upper end thereof, and has a valve 3 for selecting the water collection and the discharge of the water of the water tank into the drain pipe.

A control pipe 5 of the same material for length adjustment is connected to the lower side of the valve housing 4, and a drain hole installed at the bottom of the washroom or the toilet is not connected to the bottom of the control pipe 5 in a straight line. It is configured to install the odor prevention device (6) as a means for preventing the odor coming up through the sink (1).

The odor prevention device 6 is configured to maintain a certain amount of water discharged in the drain pipe at all times so that the odor is blocked by the water held in the drain pipe.

The common technique of the odor prevention device is configured by connecting various kinds of drain traps (7), such as k-shaped so that the water drained in the middle of the drain pipe can be maintained in a certain amount.

In the prior art as described above, even when installing the drain trap, it is necessary to select and install the control tube according to the height between the basin and the upper floor, and there is a considerable difficulty as well, because the cost of the drain trap and the control tube is expensive. This can cause the installation cost to rise.

In particular, in the case of the drain trap, when various foreign substances discharged through the wash basin are not easily discharged due to the bent unusual shape, the drain pipe becomes clogged. There are many problems, such as the need to assemble.

The present invention is designed to solve the problems as described above to facilitate the flow of water through the drain pipe connecting the upper surface of the sink and the odor prevention device that can block the odor coming up to the top of the sink in the bottom of the valve housing The purpose is to improve the constructability while reducing the production cost with the convenience of users.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

1 is an exploded perspective view showing the odor prevention device for the sink drain pipe applied to the technology of the present invention, Figure 2 will be described together with a cross-sectional view showing an important part of the odor prevention device for the sink drain pipe applied to the technology of the present invention.

The odor prevention device 30 for the sink drain pipe to which the technology of the present invention is applied,

It is provided with the bottom of the valve housing 32 including the valve 31 which is coupled to the drain hole formed in the sink to open and close, so as to facilitate the connection of the drain pipe 33, It is characterized by improving the ease of installation and drainage efficiency regardless of day or location.

The odor prevention device 30 has a hemispherical upper body 35 which is integrally formed at the lower end of the valve housing 32, and the upper body 35 and the airtight member are provided below the upper body 35. The prevention body 38 which couples the lower body 36 which is screwed through is provided.

Above the inner body of the lower body 36 is formed by protruding the overflow tube 39 so that the drained water always remains in a certain amount of the lower body 36, and above the overflow tube 39 A hemispherical diffuser 40 is incorporated to naturally diffuse water falling from the upper body 35 to the inner wall of the prevention body 38.

The support port 41 is fixed to the diffuser 40 at equal intervals to maintain a stable posture, and the height of the overflow tube 39 is such that the odor raised through the drain pipe 33 cannot move upward. Preferably, the bottom surface of the diffusion port 40 is locked.

The lower body 36 is configured to protrude downward from the connector 43 formed on the outer surface of the separation preventing means 42 so as to connect the hose or flexible drain pipe 33 so as to have excellent workability.

The present invention as described above,

The drain pipe 33 is connected to the connector 43 provided in the lower body 36 of the malodor prevention device 30 which is integrally provided below the valve housing 32, and the lower end of the drain pipe 33 is bottom surface 34. After the insertion into the drain hole of the packing 44 and the packing cover 45 to finish the installation is completed.

As described above, the odor prevention device 30 may be further integrated below the valve housing 32 to facilitate the installation of the drain pipe 33 and the sink, as well as to facilitate the flow of water.

Looking at the flow of water, the water flows down the valve housing 32 through the valve 31 of the sink, it is supplied to the prevention body 38 coupled to the lower end of the valve housing (32).

The water supplied to the prevention body 38 is smoothly flowed while hitting the hemispherical diffuser 40 embedded in the prevention body 38 and filled in the lower body 36, and water protrudes from the lower body 36. When the water level is higher than the overflow tube 39 provided to be discharged to the drain pipe 33 coupled to the connector 43 protruding below the lower body 36.

When the flow of water stops, the overflow of the water to the overflow tube 39 is stopped, and the inside of the prevention body 38 maintains the same level as the upper end of the overflow tube 39, so that the odor through the drain pipe 33. Is prevented from coming up.

This is because the lower end of the diffusion hole 40 is locked to the water level that is maintained at the same level as the upper end of the overflow tube 39, so that the odor is a passage between the upper end of the overflow tube 39 and the lower end of the diffusion hole 40. Is possible because it is blocked by water.

The present invention as described above provides a odor prevention device that can block the odor from rising to the top of the sink while facilitating the flow of water at the bottom of the valve housing connecting the sink and the bottom of the floor to reduce the user's convenience and cost While the workability can be improved, various effects can be obtained.
