Description

[0001] WATER-SAVING WATER PURIFICATION DEVICE

[0002] Technical Field

[0003] The invention relates to water purification device used to treat tap water in homes and workplaces.

[0004] The invention is particularly related to a water purification device that quickly activates the automatic shut-off valve of the diaphragm held by a perforated barrier in a clean water tank filled with purified water during the purification of tap water, thereby cutting off the flow of water entering the clean water tank and preventing waste of water.

[0005] State of The Art

[0006] Water purification devices are widely used in homes and workplaces today to clean tap water, reduce its hardness, and sweeten the water. The purification process in water purification devices is mainly achieved by filtration. In these filters, the first stage involves filtering out particles present in the tap water. During this stage, the components within the water are separated. In the second stage, the water is separated of chemicals, and its color, taste, and odor are improved using carbon filter systems. As the tap water is purified and fills the water tank in water purification devices, waste water is generated in the filter systems and discharged through the waste water outlet. On average, water purification devices discharge wastewater at a rate of 1 / 3.

[0007] In existing water purification technology, as the purified water fills the clean water tank, which is divided into a water chamber and an air chamber by a flexible diaphragm, the rubber diaphragm expands and creates air pressure within the tank. Due to this pressure, the purified water in the clean water tank is sent to the faucet connected to the device's water outlet. Additionally, when the pressure generated by the expanding diaphragm in the clean water tank reaches a certain level, tap water inlet of device is shut off and the purification process is stopped. However, in current applications, the rubber diaphragm used in clean water tanks tends to overexpand, causing a delay in triggering the automatic shut-off valve used in the device to stop the purification process. That leads to a late shutoff of tap water inlet of the water purification device, resulting in increased wastewater consumption. Therefore, a structure to prevent excessive wastewater is needed in the current state of art for water purification devices.

[0008] An example from the literature for the state of the art, as identified in our research, is document numbered TR2022 / 014401 , which we have filed. The mentioned document relates to innovation in a diaphragm water purification device. In this invention, a solenoid valve positioned between the filter chambers before the wastewater outlet is triggered by a switch located at the bottom of the rubber diaphragm, reducing wastewater consumption. However, in this water purification device, it is not possible to balance the pressure of the rubber diaphragm as it expands with clean water. This leads to the diaphragm triggering the solenoid valve late, and thus, the reduction of wastewater consumption cannot be achieved to the desired extent.

[0009] As a result, existence of above-mentioned problems and inadequacy of existing solutions made it necessary to make an improvement in the relevant technical field.

[0010] Aim of Invention

[0011] The present invention relates to a water-saving water purifier, which eliminates above- mentioned disadvantages and introduces new advantages to relevant technical field.

[0012] Main purpose of the invention is to present a water purification device that quickly activates the automatic shut-off valve of the diaphragm held by a perforated barrier in a clean water tank filled with purified water during the purification of tap water, thereby cutting off the flow of water entering the clean water tank and preventing waste of water.

[0013] The purpose of the invention is to present a water purification device which enables automatic shut-off valve to be triggered instantly when the tank is filled with purified water by grasping the rubber diaphragm superficially by means of a D-shaped barrier with a downward sloping and perforated structure in the clean water tank, which is divided into two as water and air chambers. Another aim of the invention is to present a water purification device that quickly shuts off tap water, thereby preventing wastewater wastage and enabling economical use.

[0014] To achieve all the purposes mentioned above and derived from the detailed description, the invention is related to a water purification device used for purifying tap water in homes and workplaces, which comprises; a filter connected to the tap water inlet and cleans the tap water and reduces its hardness, an automatic shut-off valve located between the filters that stops the flow of tap water, a wastewater outlet that discharges the wastewater generated in the filters, a clean water tank connected to the filters that stores the purified water, a rubber diaphragm which divides the clean water tank into two parts as water tank and air tank and flexes downwards with the filling of purified water into the clean water tank and cuts off the purified water inlet from the tank inlet; a D-shaped barrier with a downward sloping structure that prevents further flexing of the diaphragm (60) by superficially grasping the diaphragm located under the diaphragm in the clean water tank and flexing downwards with the filling of purified water into the clean water tank and ensures that the automatic shut-off valve is triggered by cutting the water inlet to the tank inlet, and at least one hole on the barrier that allows the air in the air chamber to pass towards the diaphragm to push the diaphragm upwards by opening the tap connected to the water outlet of the purifier in the air chamber.

[0029] Detailed Description of the Invention

[0030] Preferred alternatives of the water purification device are given in this detailed description only for a better understanding of the subject and without posing any limiting effect.

[0031] Figure 1 shows a representative view of the water purification device subject to the invention. Accordingly, the water purification device comprises, in its the most basic form, a filter (20) connected to the tap water inlet (10) and cleans the tap water and reduces its hardness, an automatic shut-off valve (30) located between the filters (20) that stops the flow of tap water, a wastewater outlet (40) that discharges the wastewater generated in the filters (20), a clean water tank connected to the filters (20) that stores the purified water, a rubber diaphragm (60) which divides the clean water tank (50) into two parts as water tank and air tank and flexes downwards with the filling of purified water into the clean water tank (50) and cuts off the purified water inlet from the tank inlet (53); a D-shaped barrier with a downward sloping structure that prevents further flexing of the diaphragm (60) by superficially grasping the diaphragm (60) located under the diaphragm (60) in the clean water tank (50) and flexing downwards with the filling of purified water into the clean water tank (50) and ensures that the automatic shut-off valve (30) is triggered by cutting the water inlet to the tank inlet (53).

[0032] In the water purification device subject to the invention, filters (20) that clean the tap water and reduce its hardness are connected to the tap water inlet (10). These filters (20) discharge on average 1 / 3 of the tap water as wastewater, and this discharge is managed by the wastewater outlet (40) that removes the wastewater generated in the filters (20). An automatic shut-off valve (30) is placed between the filters (20) to stop the tap water flow. The automatic shut-off valve (30) is triggered when the diaphragm (60) in the clean water tank (50), which stores the purified water connected to the filters (20), flexes downward and blocks the entry of clean water into the tank inlet (53), thus stopping the tap water flow.

[0033] Inside the clean water tank (50), a flexible rubber diaphragm (60) is placed to create pressure when the faucet is opened to send the purified water to the faucet and simultaneously stop the tap water flow. This diaphragm (60) divides the clean water tank (50) into a water chamber (51) and an air chamber (52). The lower part of the clean water tank (50) forms the air chamber (52), and the upper part forms the water chamber (51).

[0034] The purified water from the filters (20) enters the clean water tank (50) through the tank inlet (53) and fills the water chamber (51), causing the diaphragm (60) to flex downward. As water continues to fill the water chamber (51), the diaphragm (60) continues to flex downward. Only when the diaphragm (60) stops flexing does the entry of purified water from the tank inlet (53) stop, triggering the automatic shut-off valve (30) to block the water entry at the tank inlet (53) and stop the tap water flow at the tap water inlet (10), thereby halting the purification process. Due to the cutting process being dependent on the flexing capability of the diaphragm (60), the filtration process continues as tap water flows from the tap water inlet (10) into the filters (20), resulting in the continuous discharge of wastewater from the wastewater outlet (40). Since the ratio of wastewater discharge is three times higher than that of purified water, the wastage of wastewater is substantial.

[0035] In our invention, to eliminate wastewater wastage, a D-shaped barrier (70) with a downward slope is positioned under the diaphragm (60) that flexes as purified water fills the water chamber (51). This barrier (70) superficially grasps the diaphragm (60) flexing with the water filling the water chamber (51), preventing further flexing of the diaphragm (60). Thus, the diaphragm's (60) excessive flexing is stopped by the barrier (70). When the water chamber (51) is completely filled, the entry of purified water from the tank inlet (53) is blocked, and the automatic shut-off valve (30) stops the tap water flow at the tap water inlet (10), halting the purification process. Consequently, since the filtration process cannot continue in the filters (20), wastewater wastage is prevented. At least one hole (71) is formed in the barrier (70). This hole (71) allows air from the air chamber (52) to pass towards the diaphragm (60) to push it upwards. Thus, when the faucet connected to the water outlet of the purification device is opened, the air passing through the hole (71) from the air chamber (52) pushes the diaphragm (60) upwards, sending the purified water from the water chamber (51) to the user.
