Description

  The present invention relates to a hair catcher that is attached to a circulation filtration device and used to remove relatively coarse foreign matters.

  Circulating filtration devices are used to remove contaminants contained in water in each facility such as a circulating bathtub, a pool, a waterscape facility, and rainwater use. The hair catcher is attached to the circulation filtration device and is used in advance to remove relatively coarse contaminants such as human hair and leaves so as not to damage the circulation pump.

When circulating filtration is performed, the removed contaminants accumulate in the hair catcher. According to the guidelines of the Ministry of Health, Labor and Welfare, the hair catcher is cleaned daily. The conventional hair catcher is equipped with a detachable lid at the top opening, removes the lid during cleaning, and the upper end provided inside directly collects contaminants collected in the mesh-like coarse contaminant trapping part with an opening. It was to be removed. Since this structure requires human hands, daily time and labor costs are required for cleaning. In addition, as a solution, there was a hair catcher that used the same cleaning method as the filtration device to perform a backwashing process to remove contaminants by backflowing the liquid, but complicated piping and operation of many valves were required. I was trying. In any case, since the disinfection process in the hair catcher was not included, only cleaning was performed.

  Therefore, the problem to be solved by the present invention is to provide a hair catcher that can be used in a sanitary and clean manner by removing and disinfecting contaminants with a simple structure without human intervention.

  In order to solve the above problems, the present invention provides a liquid inflow pipe at a lower portion of the side surface, a liquid outflow port A at an upper portion of the side surface, and a separate liquid outflow pipe at a position where it does not overlap with the liquid inlet at the lower end closed portion or the lower side surface Connected and equipped with an internal mesh-like coarse contaminant trapping part opposite to the conventional one, with the lower end being open and the upper end being closed. At this time, a straight line formed by connecting the liquid outlet A and the liquid inlet is provided so as not to pass through the center when viewed from the upper end of the main body.

  When the present invention is used, a pipe for drawing water from a bathtub or a pool is connected to the liquid inlet side, and a pump is provided on the liquid outlet A side. The pump is connected to a filtration device. The liquid outflow pipe is connected to a two-way valve, and the tip of the two-way valve is connected to a drain pipe.

  When the pump is operating, the liquid in the bathtub or the pool flows in from the liquid inlet of the present invention through the pipe and flows out from the liquid outlet A in the pump direction. The upper and lower sides of the liquid inlet and the liquid outlet A are reversed from those of the conventional product, but there is no problem because the liquid is circulated by the suction force of the pump. At this time, it is necessary to close the two-way valve connected to the liquid outflow pipe.

  Since the straight line formed by connecting the liquid outlet A and the liquid inlet does not pass through the center when viewed from the upper end of the main body, the liquid rises while causing a vortex inside. Since this eddy current exists as long as the pump is operated, that is, as long as the filtering device is operated, the trapped coarse contaminant is not adsorbed by the mesh-like coarse contaminant trapping portion of the present invention. Keeps floating inside. Further, since the liquid outlet A is on the upper side and the liquid is sucked in the direction of the liquid outlet A by the pump, the liquid inside the present invention is concentrated upward.

  When the operation of the pump is stopped, the liquid concentrated upward falls downward while entraining coarse contaminants. Furthermore, liquids in the pump and between the hair catcher and the filtration device are also drawn by siphoning. At this time, when the two-way valve connected to the liquid outflow pipe is opened, coarse contaminants captured from the liquid outlet B are discharged together with the liquid. However, since the liquid inlet is also open, in order to prevent backflow to the water tank, a backflow prevention valve or a two-way valve is installed on the pipe outside the liquid inlet.

  In paragraph No. 0005, even when the internal mesh-like coarse contaminant trapping part is installed so that the upper end is open as in the conventional case, the mesh-like coarse contaminant trapping part is not in close contact with the inner wall of the main body and liquid By installing at the same height as the upper end of the inlet and the liquid outlet B, the same effect can be obtained. That is, in this case, coarse contaminants remain in the space between the mesh-like coarse contaminant trapping portion and the inner wall of the main body, and only the liquid that can pass through the mesh portion passes through the mesh and flows out from the liquid outlet A. When the operation of the pump is stopped, the liquid that has gathered upward falls in the same manner as described in paragraph 0009 and falls downward while entraining coarse contaminants, and is discharged from the liquid outlet B.

  When water used for bathing is filtered, according to the guidelines of the Ministry of Health, Labor and Welfare, chlorinated chemicals are injected and sterilized just before the water enters the filtering device. This is to disinfect not only water but also the inside of the filtration device. However, in the conventional structure, the disinfection effect in the pump and the hair catcher installed closer to the bathtub than the chemical liquid injector is not expected. Therefore, when the present invention is used, as described in paragraph 0009, since the water in the pump and between the hair catcher and the filtration device is drawn into the present invention due to the siphon phenomenon, the liquid outflow occurs when the pump is stopped. The pump and hair catcher can be disinfected by opening the two-way valve connected to the valve and at the same time injecting an appropriate amount of disinfectant solution from the solution injection device provided immediately before the filter device, that is, between the pump and the filter device. It becomes.

  There are other methods for disinfecting water used for bathing, such as methods using non-chlorine chemicals, heat disinfection, UV generators, ion generators, and ozone generators. However, since the sustainability of the effect is insufficient and the disinfection ability is insufficient for disinfecting the device, it is insufficient for use in the disinfection system of the present invention.

  The present invention eliminates the need for human hands to remove coarse contaminants trapped within the hair catcher, requiring only periodic cleaning and inspection, saving time and labor costs, and saving money. Is. Further, since disinfection is performed together with removal of coarse contaminants, it can be used in a sanitary and clean manner without taking time and effort.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external view of the present invention. With respect to the hair catcher body of reference numeral 1, the liquid inlet of reference numeral 2 is connected to the lower part, and the liquid outlet of reference numeral 3 is connected to the upper part. Further, a structure is adopted in which the mesh-like coarse contaminant trapping part 6 is not moved by the liquid flow.

  FIG. 2 represents the internal structure of the present invention. In the present invention, the liquid in a water tank such as a bathtub or a pool normally flows from the liquid inlet port 2 to the liquid outlet port A 4 during the normal filtration operation. At this time, since the line passing through the center of the main body represented by the imaginary line 8 is shifted from the center line as shown by the imaginary line 9 in the figure viewed from the upper end opening in FIG. The liquid flowing inside rises while causing a vortex. Due to this eddy current, coarse contaminants continue to float inside without being adsorbed by the mesh-like coarse contaminant trapping part 6.

  When the operation of the pump is stopped, the liquid in the vicinity of the upper space of the hair catcher denoted by reference numeral 7 falls due to gravity and is drained from the liquid outlet B denoted by reference numeral 4 while entraining coarse contaminants.

  4 and 5 show the liquid flow described in paragraphs 0015 to 0016 and the connection of surrounding pipes and components. The flow during the normal filtration operation described in paragraph 0015 is shown in FIG. The liquid in the water tank is sucked by the pump of reference numeral 11, passes through the check valve of reference numeral 13, flows to the present invention of reference numeral 10, and flows out to the pipe connected to the filtration tank. At this time, the drainage electric two-way valve 12 is kept closed. At the time of backwashing, the drainage electric two-way valve 12 is opened and drained as shown in FIG. Since there is a backflow prevention valve 13, the liquid is drained without flowing back to the water tank. Since the suction force is lost by stopping the pump, the liquid remaining in the pipe between the present invention (10) and the pump (11) is also drawn by the siphon phenomenon and drained together.

  At the time of backwashing, when the disinfecting chemical solution is injected from the chemical solution injection device represented by reference numeral 20, it is drained through the pump of reference numeral 11 and the present invention of reference numeral 10 together with the water in the pipe. Ten disinfections can be performed. In the conventional hair catcher and piping structure, water is drained as it is after washing the inside of the filtration device without passing through the pump and hair catcher of 11 at the time of backwashing. Cannot be disinfected.

  6 and 7 show the flow of the liquid when the liquid outlet B is connected to the lower end closing portion of the present invention indicated by reference numeral 10. Since there is no difference other than the position of the liquid outlet B, the flow is the same as that described in paragraph 0017. In addition, the disinfection mechanism during backwashing is the same as that described in paragraph 0018.

  8 and 9 are general views of a circulation system including a filtration device 14 and a water tank 15. As shown in FIG. 8, when the water tank 15 is placed above the present invention 10, the effect can be obtained by the structure shown in the paragraph number 0017 and FIGS. 4 to 7. On the other hand, as shown in FIG. 15, when the water tank 15 is placed below the present invention 10, a siphon phenomenon occurs, and the effect of the backflow prevention valve is insufficient. As an alternative, an electric two-way valve for liquid inlet 16 is attached.

  Although the cleaning effect can be obtained even if the valves 12 and 16 are manually operated, the operation of the valves needs to be performed by human hands. The form which adds automatic control is good.

  10 and 11 are diagrams of a mesh-like coarse contaminant trapping unit 6. 10 is a side view, and FIG. 11 is a view from the upper end closing portion. Since the upper end is closed, a handle 18 is provided so that it can be easily removed for maintenance.

  The mesh-like coarse contaminant trapping part indicated by reference numeral 6 can achieve the effect of the present invention even when the entire surface is meshed, but it is difficult to confirm the amount of trapped contaminants. The form which equips the closing part with the window is good. A transparent acrylic or glass plate is used so that the inside of the window can be confirmed even when the window is closed. At this time, when a transparent acrylic or glass plate is similarly used for the lid portion 5, the inside can be confirmed without touching the present invention.

  FIG. 12 to FIG. 14 show an embodiment in which the mesh-like coarse contaminant trapping part 6 is installed in such a direction that the upper end becomes an opening. FIG. 12 represents the internal structure of the present invention. FIG. 13 shows the connection of peripheral piping and parts using the embodiment of FIG. 12 and the flow of liquid during normal operation. FIG. 14 shows the connection of peripheral piping and parts using the embodiment of FIG. 12 and the flow of liquid during backwashing.

  As shown in FIG. 12, when the mesh-shaped coarse contaminant trapping part denoted by reference numeral 6 is installed with the upper end being opened, the mesh-shaped coarse contaminant trapping part denoted by reference numeral 6 is connected to the main body denoted by reference numeral 1. It is necessary to install so as not to be in close contact with the inner wall. This is because it is necessary to make a space for capturing the coarse contaminants on the side surface of the mesh-like coarse contaminant capturing portion and the outer surface of the lower end closing portion. Further, a structure is adopted in which the mesh-like coarse contaminant trapping part 6 is not moved by the liquid flow. In FIG. 12, it is represented by reference numeral 19. Further, the positional relationship of the liquid inlet, the liquid outlet A, and the liquid outlet B as viewed from the upper end opening side is the same as that in FIG. 3, and the circulation system including the filtration device 14 and the water tank 15 is shown. The overall view is the same as FIG. 8 and FIG.

  As shown in FIG. 13, the liquid during normal operation rises while causing a vortex in the present invention denoted by reference numeral 10 and flows out in the pump direction denoted by reference numeral 11. This flow is the same as in the case of paragraph 0017 except for the installation method of the mesh-like coarse contaminant trapping unit 6 and the coarse contaminant trapping method. Further, as shown in FIG. 14, the liquid at the time of backwashing descends while causing a vortex flow in the present invention of reference numeral 10 and flows out in the direction of the two-way valve of reference numeral 12. This flow is the same as in the case of paragraph 0017 except for the installation method of the mesh-like coarse contaminant trapping unit 6 and the coarse contaminant trapping method. In addition, the disinfection mechanism during backwashing is the same as that described in paragraph 0018.

  The present invention can be applied to general equipment for purifying liquid using a filtration device, and can be replaced with a conventional hair catcher in equipment for moving liquid using a pump without a filtration equipment.
