Description

  The present invention relates to a kind of seamless drainage pipe or sink trap structure, and more particularly, to a drainage connection structure without a metal sink seam, which can clean a kind of drain outlet cleanly and has a sanitary effect.

Most sinks on the market are metal sinks made of stainless steel so that they can withstand use and are easy to clean or clean. A metal sink is used to wash kitchen dishes, teacups, or fruit and vegetables, and generally drains by connecting a drain pipe to the drain. In order to avoid clogging the drain pipe, a sink trap is usually connected to the drain port of the metal sink, and impurities in the drainage are filtered through filter holes or nets of filter parts in the sink trap. The production of metal sinks is a thin shell (thin wall) sink body that is usually molded by sheet metal processing technology in consideration of cost, and because the sink bottom is thin, a drain pipe or sink trap at the drain end of the drain outlet It is difficult to fix the connection.
For example, in the structure of the sink trap, Taiwanese utility model No. M383593 “Improved structure of sink sink for sink tank” extends from the drain of the sink bottom to the sink trap. The sink trap is fixed to the surface of the sink bottom by the edge of the sink trap, and fixed to the end of the sink bottom together with the water stop gasket using a single fixing ring. Secure to.
However, the water-stop gasket is very thin or does not match the water-stop gasket, and one gap is formed between the installation edge and the sink bottom. In view of the fact that the gaps are clogged with dirt (molds and off-flavors are generated), are difficult to clean, and affect the aesthetics and hygiene of the sink.

Taiwan Utility Model No. M383593 JP2013-104202A

  In order to solve the drawbacks of the known structure, it is a main object of the present invention to provide a drainage connection structure without a metal sink joint.

In order to solve the above-mentioned object, the present invention provides a drainage connection structure without a metal sink joint. The main purpose of the present invention is to provide a single drainage outlet at the sink bottom of the metal sink. The drain port stretches and molds one frame ring outward from the wall of the tank at the bottom of the sink. One connection sleeve is fixed to the outer periphery of the frame ring, and one male screw is formed on the outer edge of the connection sleeve.
When a metal sink is installed and used, the drain pipe or sink trap at the drain end serving as a drain outlet is screwed and fixed with the male thread of the connection sleeve through the female thread on the inner edge of one screw cover. Alternatively, a sink trap completes the connection with the drainage frame ring. Alternatively, a sink trap having an internal thread inside is directly screwed onto the external thread of the connection sleeve and fixed, and connected to the frame ring of the drain port.
The structure of the whole drain outlet is easy to connect the drain pipe or sink trap and the frame ring, and extends from the sink bottom of the metal sink through the drain ring frame ring to form a complete frame body Therefore, the drainage end of the drainage port is connected to the drainage pipe or the sink trap without a seam, and the sanitary effect is achieved.

  The next object of the present invention is to provide a kind of drainage connection structure without a metal sink joint. The connection sleeve is welded and fixed on the outer surface of the frame ring, so that the connection sleeve is permanently and firmly coupled to the frame ring and does not come off.

A further object of the present invention is to provide a drainage connection structure without a metal sink joint. One filter component is packed in the frame ring, a filter portion is provided on the filter component, and one lid recess is formed, and one sink trap lid for closing the filter portion is provided in the lid recess.
When water is put into the metal sink, the sink trap lid can prevent the liquid in the metal sink from being discharged from one end of the frame ring of the drain port. On the contrary, when the sink trap lid is opened, in the process in which the dirty liquid in the metal sink is discharged from one end of the frame ring of the drain port, it is effective in filtering dust when draining using the filter part of the filter part. Reach.

  According to the structure of the present invention, the drain end of the drain port is connected to the drain pipe or the sink trap without a seam, so that the cleaning is easy to clean and the sanitary effect is achieved.

It is a structural exploded view of the present invention. It is assembly structure sectional drawing of this invention. It is the state schematic at the time of connecting the drain pipe of this invention. It is the state schematic at the time of connecting the sink trap of this invention. It is the state schematic at the time of connecting the sink trap of the plastic injection molding of this invention.

  Hereinafter, the structure, features, and effects of the present invention will be described in detail with reference to the best embodiments and drawings.

This is a drain connection structure without a kind of metal sink joint.
As shown in FIGS. 1 and 2, one drain port 20 is provided in the sink bottom 11 of one stainless metal sink 10. The drain port 20 stretches and molds one frame ring 13 outward from the wall of the sink bottom 11 tank. One connection sleeve 30 is fixed to the outer periphery of the frame ring 21, and one male screw 31 is formed on the outer edge of the connection sleeve 30. As shown in FIGS. 3 and 4, when the metal sink 10 is installed and used, the drain pipe 40 or the stainless steel sink trap 50A (which is connected to the sink basket 51 and the bottom end) is used as the drain port 20. (Including one drainage connection pipe 52) is screwed and fixed to the male thread 31 of the connection sleeve 30 through the female screw 61 on the inner edge of one screwing cover 60, so that the drainage pipe 40 or the sink trap 50A is connected to the drainage port. The connection with the 20 frame rings 21 is completed.
As shown in FIG. 5, or a plastic injection-integrated sink trap 50 </ b> B (including a sink basket 51 and one drainage connection pipe 52 connected from the bottom end) is directly connected to the male thread 31 of the sleeve 30. To the frame ring 21 of the drain port 20.
As shown in FIGS. 3, 4, and 5, the structure of the drain outlet 20 as a whole is easy to connect the drain pipe 40 or the sink traps 50, 50 </ b> A and the frame ring 21, and through the frame ring 21 of the drain outlet 20, By extending outward from the sink bottom 11 of the metal sink 10 to form a complete frame body, the drainage end of the drainage port 20 is connected to the drainage pipe 40 or the sink traps 50A and 50B without a seam. The effect is easy to clean and clean.

  Based on the above embodiment, as shown in FIG. 2, the connection sleeve 30 is welded and fixed to the outer surface of the frame ring 13, so that the connection sleeve 30 is permanently and firmly coupled to the frame ring 13. Do not leave.

Based on the above embodiment, as shown in FIGS. 1 and 2, one filter component 70 is packed in the frame ring 21, a filter portion 71 is provided on the filter component 70, and one lid recess 72 is provided. One sink trap lid 73 that is formed and closes the filter portion 71 in the lid recess 72 is provided.
As shown in FIGS. 3, 4, and 5, when water is poured into the metal sink 10, the sink trap lid 73 causes the liquid in the metal sink 10 to be discharged from one end of the frame ring 21 of the drain port 20. Can be blocked. Conversely, when the sink trap lid 60 is opened (not shown in the figure), the filter portion 71 of the filter component 70 is used in the process of discharging dirty liquid in the metal sink 10 from one end of the frame ring 21 of the drain port 20. And reaches the effect of filtering trash when draining.

  The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. Those who are familiar with this technology can make appropriate changes and adjustments, such as changes in the fixing structure, and these changes and adjustments do not lose the significance of the present invention and are included in the scope of the present invention. It is.
