Abstract

(57) [Summary] (Problems corrected) [PROBLEMS] To provide a sanitary strainer which does not need to touch the outer peripheral surface of the filter 3 or the plug 4 when taking out the filter from the strainer body and cleaning it. SOLUTION: A cylindrical wire mesh filter 3 is provided at an open end of a short pipe 2 obliquely branched from a straight pipe 1 through which clean water passes.
By inserting and screwing a plug body 4 having a series of pipes, the wire mesh 3 intersects the water passage of the straight pipe 1, and in a strainer configured to filter tap water, a pinch is provided on the outer end face of the plug body 4. 5 were connected in series.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a strainer for filtering drinking water.

[0002]

[Prior art]

 In equipment that normally uses tap water, a strainer must be connected to the water pipe on the upstream side of the equipment in order to prevent the danger that the water solenoid valve, etc., may be damaged by foreign substances that may be generated during construction of the water pipe. The foreign matter is removed by a filter built into the strainer. FIGS. 3 and 4 show a conventional strainer of this type, in which a short pipe 2 is branched diagonally from a straight pipe 1 through which clean water passes, and a cylindrical pipe is formed at the open end of the short pipe 2. The filter 3 is inserted into the water passage of the straight pipe 1 by inserting and screwing the plug 4 into which the filter 3 made of a wire mesh is screwed, and the tap water is filtered.

[0003]

[Problems to be solved by the invention]

 In the conventional strainer, the plug 4 is attached and detached by engaging a driver or a coin with a driver groove 15 formed on the outer end face of the plug 4 and rotating the plug 4. Was. However, drivers often have mechanical oil or rust attached to them, and coins often have large amounts of germs attached to them. At the time of the periodic inspection, the filter 3 is washed by holding the plug 4 directly with the hand touching the driver or the like, so that there is a disadvantage that the water passage is easily stained. An object of the present invention is to solve such a problem and to provide a strainer of this type that can clean a filter without touching a water passage section.

[0004]

[Means for Solving the Problems]

 According to the present invention, as shown in FIGS. 1 and 2, a plug 4 having a cylindrical wire mesh 3 connected to an end face thereof is connected to an open end of a short pipe 2 obliquely branched from a straight pipe 1 through which clean water passes. A strainer in which the wire mesh 3 crosses the water passage of the straight pipe 1 by being inserted and screwed to filter the tap water, and a knob 5 is continuously provided on the outer end surface of the plug 4. When the plug 4 is taken out and washed at regular intervals, the plug 4 is prevented from touching the hand to prevent invasion of various bacteria into the water passage.

[0005]

[Embodiment of the invention]

 1 and 2 show an embodiment of the present invention. The strainer body has a Y-shape in which a short pipe 2 is diagonally branched from a straight pipe 1 having pipe connection portions 6 and 7 formed at both ends. A plug 4 having a cylindrical wire mesh filter 3 connected to the end surface thereof is inserted and screwed into the open end of the short tube 2. The wire mesh 3 is formed integrally with a plastic frame 8, the base end is fixed to the end face of the plug 4 with a screw 9, the tip is open, and when the plug is completely closed, the tip is closed. The wire mesh 3 crosses the water passage of the straight pipe 1 and filters the clean water passing through the straight pipe 1. That is, an oblique partition plate 10 is provided in the straight pipe 1 so as to block the water passage, and the partition plate 10 is inclined so as to be perpendicular to the axis of the short pipe 2. The open end face of the cylindrical wire mesh 3 is in contact with the drilled circular hole 11. Therefore, the water flowing from the upstream flows into the wire mesh 3 and is filtered as it exits through the mesh from the peripheral surface of the wire mesh. A flange 12 is formed at the outer end of the plug 4 so as to abut the end face of the short pipe 2, and the above-described knob 5 is integrally protruded from the outer end face of the flange 12. Reference numerals 13 and 14 are O-rings.

[0006] In use, the strainer according to the present invention and the short pipe 2 face downward as shown in Fig. 1 in the water pipe on the upstream side of equipment using tap water such as a dishwasher or a pottery apparatus. Intervene as follows. Water flows in the direction of the arrow, and since the upper end of the cylindrical filter 3 made of wire mesh is open, foreign matter such as metal fragments generated during water pipe work accumulates in the cylindrical filter 3 and the inside of the equipment is removed. There is no risk of adversely affecting the water solenoid valve. Foreign substances and the like in the filter 3 are regularly inspected and washed and removed. At this time, the knob can be easily opened by the knob 5 without bringing tools or coins into the cooking place. The cleaning can be performed without touching the screw portion of the plug 4 with the hand.

[0007]

[Effect of the invention]

 According to the present invention, as described above, when removing the wire mesh filter 3 from the strainer body and cleaning it, the knob 5 is picked up and the stopper 4 is rotated to remove the stopper 4 from the short pipe 2. Therefore, it is possible to easily wash the water without touching the outer peripheral surface of the filter 3 or the plug 4, so that there is no possibility that germs may enter the water passage, and a driver or a coin may be placed in the cooking place. It has the advantage of being sanitary because there is no need to bring it in.
