Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a suction port in a bathtub that circulates and filters hot water.

0002

[Conventional technology]

Piping connects the hot water inlet and outlet in the bathtub with an outdoor filter or water purification device. This type of hot water is filtered while circulating the hot water through a circulation system. In a purification device, the suction port is just an opening to which a filter is attached. It was a department.

0003 By the way, when I replaced the hot water, cleaned the bathtub, and restarted the filter, the filter If the pump in the bathtub is a self-priming type, you can easily restart the operation by filling the bathtub with water. However, self-priming pumps are large, have a low discharge volume, and consume a lot of electricity. There is a big drawback.

0004 Therefore, if you try to use a cheaper magnet pump or line pump, When restarting operation, be sure to fill the space between the pump and the suction port of the bathtub with water. It took a lot of time and effort.

[0005] Also, if the filter is located above the bathtub, install a foot valve at the suction port. Even if a self-priming pump is used, the air must be kept together for a significant period of time. There was also the issue of noise during the delivery process. Moreover, recently I have been using bath additives and bathing frequently. I had to solve this problem in order to replace it with .

[0006] The inventor of this invention previously proposed in Utility Application No. 2-72012 that the water level in the bathtub should be lower than the outlet. When the water level reaches the discharge port, the filter will automatically stop operating and water will be added again until the water level reaches the discharge port. We are proposing a device that automatically restarts operation when this point is reached. This device filters A check valve is installed inside the machine to automatically restart the machine, but the bathtub is larger than the filter. If the unit is in a subordinate position, the magnet pump or line pump will automatically resume operation. I couldn't go to

[0007] Additionally, foot valves are extremely inconvenient for cleaning human hair and other deposits. It was.

[0008]

[Problem that the invention attempts to solve]

The problem we are trying to solve is when the bathtub is located below the circulation path or when the bathtub is For top pumps and line pumps, operation cannot be restarted immediately, and check valves are clogged. The problem is that it is not easy to clean the garbage etc.

[0009]

[Means to solve the problem]

To solve this problem, the inventor installed a removable check valve in the suction port of the bathtub. At the same time as the filter pump stops, the hot water inside the filter and the pipes flows from the suction port into the bathtub. In addition to preventing the check valve from flowing inside, it also makes it easier to clean the check valve when it becomes clogged with dirt. We have proposed a bathtub suction port that can be easily installed.

0010 More specifically, the hot water in the bathtub is circulated by connecting it to the suction port and discharge port in the bathtub. A bathtub that is filtered by a filtration element while being circulated by the suction force of a pump via a circular path. At the suction port in The structure consists of a check valve that can be freely closed by a spring and is detachably attached. Features.

[0011]

[Effect]

The check valve at the suction port prevents the pump from sucking hot water while the pump is operating. The valve opens due to gravitational force, and when the pump stops and no longer receives suction force. , the valve closes automatically when pushed by a spring. As a result, the check valve opens at the same time as the filter stops. is closed, and the hot water in the circulation system cannot flow out from the suction port and is stopped within the same system.

【Example】

Hereinafter, an example of implementation of the present invention will be described in detail with reference to the drawings.

[0013] 1 in the figure is a bathtub, and a suction port 2 and a discharge port 3 in this bathtub 1 are connected to a circulation system. 4 is piped, and the hot water in the bathtub 1 is pumped by the suction force of the pump 5 in the middle of the same line 4. is sucked in from the suction port 2 and then refluxed into the bathtub 1 from the discharge port 3 via the circulation system path 4. I try to keep it in circulation.

[0014] The suction port 2 has a known structure, and a cylindrical mouth body 7 is inserted into the hole 6 of the bathtub 1 from inside the bathtub. The tube 9 is screwed onto the threaded portion 8 of the mouth body 7 which protrudes to the outside of the bathtub 1 while the mouth body 7 is inserted. By sandwiching the side wall part around the hole 6 between the flange 10 of the pipe 9 and the flange 11 of the pipe 9. is forming. The mouth body 7 has protrusions 12 facing each other inside near the opening, and is screwed. When screwing the tube 9 onto the portion 8, the mouth body 7 is prevented from rotating by pressing the protrusion 12. I'm trying to make it easier to eat.

[0015] A mounting body 13 equipped with a check valve 14 and a filter 15 are attached to the suction port 2, respectively. It is installed from inside the bathtub. The mounting body 13 has a diameter that can be inserted into and removed from the suction port 2. It is formed into a cylindrical shape, and the flange 16 at the front end is attached to the flange 10 at the mouth body 7. The spiral locking collars 18, 18 are attached to the protrusions 12, 12 on the rear side, respectively. The flanges 10 and 16 are fitted closely together with no gap between them. . In addition, there is a gap between the opposing locking flanges 18, 18 that allows the protrusions 12, 12 to pass in the axial direction. part 19 is open, and the mounting body 13 is attached to the mouth body 7, so that the protrusion 12 and the spacing part 19 are oriented in the axial direction. It can be inserted and removed freely when it is matched, and it can also be rotated when it is inserted, that is, it can be rotated on the drawing. Turn it clockwise to tighten and fix it, and turn it counterclockwise to remove it from the fixed state. So Therefore, the flange 16 is provided with finger hooks 20 in the radial direction, and the finger hooks 20 can be hung on the finger hooks 20. It is designed to be easy to turn and operate.

[0016] The check valve 14 at the rear end of the mounting body 13 in the suction port 2 is connected to the rear end of the water passage hole 21 in the mounting body 13. A valve body 23 that can open and close the opening 22, and a stopper 24 that attaches the valve body 23 to the opening 22 position. is built into the valve body 23, and closes the valve body 23 with a spring force that is weaker than the suction force of the pump 5. It consists of a spring 25 which is biased into the valve state. This valve body 23 is used to operate the pump 5. Sometimes the valve is drawn to the open state away from the opening 22, and the hot water in the bathtub 1 is drawn to the open state. It is designed so that it can circulate through the section 22, and when the pump 5 stops operating. The opening 22 is pressed by a spring 25 so that the opening 22 can be closed tightly.

[0017] The filter 15 has an opening 27 at the bottom of a flat accommodation case part 26 with a round front face. On the back side of the storage case section 26, there is a connection port formed protrudingly in communication with the inside of the storage case section. 28 is detachably inserted into the mounting body 13. Also, the attachment and detachment of the filter 15 to the mounting body 13 is , mounting means such as fasteners or screws may be used, but the connection port 28 may be installed through the mounting body Just insert it into the water hole 21 and the pump's suction pressure will prevent it from falling out. And the containment case A water-resistant urethane sponge filter 29 is housed on the connection port 28 side in the space 26. The opening 27 is connected between this filter 29 and the inner surface of the housing case portion 26 facing each other. A hot water inflow space 30 is formed. In addition, the storage case part 26 is attached to the front and rear containers 31 and 32. The front body 31 is removed and the filter 29 is removed from the rear body 32. It can be taken out and washed.

[0018] Filter 29 is a flat type with a large hot water inlet area and a large contact area with hot water. A flat type is preferred, and a flat type is easy to clean. As this filter 29, For example, in an embodiment consisting of a water-resistant urethane sponge with a desired mesh, two meshes A combination of different water-resistant urethane sponges that are coarse on the entrance side and fine on the back side. , the water-resistant urethane sponge on the inlet side and the ultra-superfine fibers on the back side are made into a micro-sponge shape. Examples include embodiments in which the material is combined with a nonwoven fabric. In addition, combinations with metal ion generators There are also combinations, such as amorphous copper, high-purity ultrafine copper fiber, and ceramic silver support. A combination with a body etc. held in a net-like body through which water can pass, specifically, Leave an inflow space for hot water, place a filter on the suction port side, and place a metal ion generator on the other side. are placed facing each other, and the metal ion generator is polymerized on the rear side of the filter. Examples include aspects such as: As another aspect, metal ions are added to the water-resistant urethane sponge. There are also products that carry a metal ion generator, and the sterilization effect of hot water due to the metal ion generator is can get.

[0019] Further, a water heater may be connected to the circulation system path 4, and the heated hot water is supplied to the circulation system path 4. It is possible to circulate and heat the water by refluxing it into the bathtub 1 through the bath. Pump 5 is a normal type However, there are cases where a self-priming type with the same capacity is used, and there are also magnetic pumps and line pumps. It may be a pool.

[0020] Therefore, according to the embodiment, the valve body 23 is open while the pump 5 is operating. The valve waits in an open state away from the mouth part 22, and the hot water in the bathtub 1 is first filtered by the filter 15. After that, it passes through the opening 22 and circulates. Then, when pump 5 stops operating, , the valve body 23 is pushed by the spring 25 to close the opening 22 and close it. Thereby The hot water in the circulation path 4 accumulates in the same path and does not flow out from the suction port 2.

[0021] To attach the check valve 14 to the suction port 2, use the anti-rotation protrusion on the existing mouth body 7. 12 can be used to removably tighten and fix the check valve 14. There is no need to change the suction port 2, and the construction work is simple and easy. Moreover, the check valve 14 The closing action of the valve body 23 is handled by the spring 25, eliminating the vertical relationship during installation. Therefore, even an amateur can install it with ease.

[0022]

[Effect of the idea]

stomach. The suction port is automatically closed as soon as the pump stops operating, so the circulatory system The hot water that was circulating until the pump stopped remains on the roadside. Thereby, the bathtub When draining the hot water inside the bathtub, cleaning the bathtub, and replacing the hot water, do not remove the hot water inside the circulation system. Because water does not flow out of the suction port, turn on the pump immediately after replacing the hot water in the bathtub. Operation can be restarted and hot water in the bathtub can be circulated and filtered.

[0023] B. It is possible to eliminate the restriction on the vertical relationship between the bathtub and the circulation system road, and the circulation system road side can be When the installation range has expanded and the circulation system path can only be installed above the bathtub due to the location. It can also correspond to In addition, it is possible to eliminate pump type restrictions, making it economical. Magnet pumps and line pumps, which are advantageous, can be used.

[0024] C. The check valve is removable from the suction port, so if it becomes clogged with dirt, the check valve can be removed. can be removed and cleaned easily.
