The applicant hereby gives notice and description of relevant background information prior to the filing of embodiments of the present application in order to provide a clear understanding and appreciation for the present application.

Ozone is an oxygen isomer, is a strong oxidant, can naturally decay into oxygen at room temperature, has a decay period of 15 to 25 minutes, can be rapidly converted into ecological oxygen in water, has no residue problem, and can destroy chemical bonds of organic pesticides by strong oxidation to cause the organic pesticides to lose medicinal properties and kill various bacteria and viruses on the surfaces of food materials. The effect of ozone for removing bacteria is 1.5 times of that of chlorine, and the sterilization speed is 600-3000 times faster than that of chlorine.

Ozone is an efficient and rapid pesticide residue removing bactericide, can rapidly dissolve pesticide residues in a short time, can effectively degrade the pesticide residues in rice, vegetables and fruits, can rapidly kill bacteria and viruses, and can prolong the storage life. And the time required by ozone disinfection is short, the ozone disinfection does not need to be cleaned again after disinfection, no harmful residues and no secondary pollution exist after ozone disinfection, the ozone is automatically decomposed into oxygen after disinfection, no peculiar smell and no pollution exist, and the ozone disinfection is comprehensive, good in effect and low in use cost.

Although ozone has the above advantages, it is very difficult to maintain a suitable and non-exceeding concentration in water because ozone escapes from water, and it is more desirable to maintain ozone at a suitable concentration that is not exceeded in domestic water, especially considering that ozone, as a strong oxidant, reacts with almost any biological tissue.

Because ozone is difficult to store, only a mode of using the ozone at any time can be adopted at present. The existing ozone generation mode is that partial oxygen in air is converted into ozone by utilizing high-voltage ionization. The existing method of mixing ozone into water is also to prepare ozone by high-pressure ionized air, and then to feed ozone into water through air feed pipe to dissolve, which requires special complex air dissolving structure, high air dissolving pressure, and also needs to face the problem of treatment of undissolved ozone. Considering the flow rate of water and the time required for dissolution, the ozone concentration in the existing ozone water has large variation range, so that the ozone concentration in the water cannot be controlled, and further development and application of ozone in daily life are limited.

Although some products use ozone for sterilization and disinfection at present, most of the products mix ozone before heating, and after the products are heated to high temperature, the ozone in the water basically escapes completely, so that the output water basically loses the effect of removing pesticide residues, and correspondingly, the products mainly use the ozone for sterilization and disinfection. Even though some products mix ozone into cold water to remove pesticide residues, the further development of the products is limited because the ozone concentration in the output water cannot be controlled to be proper.

The ozone concentration is understood to mean the ozone content per unit volume of water. The ozone is present dissolved in the water and/or in the form of bubbles.

As shown in fig. 1-5. In an embodiment of the present invention, a multifunctional waterway 1 is provided, and the multifunctional waterway 1 may be integrated into a water device such as a water heater, a faucet, and a mixing valve 50, and may also be manufactured as a separate waterway module and used in a waterway outside the water heater, the faucet, and the mixing valve 50, which is not limited in this application.

Specifically, this multi-functional water route 1 includes: a first water circuit 100, a second water circuit 200, a flow sensor 10, a temperature sensor 20, and an ozone generating module 30. The water output by the first water path 100 and the water output by the second water path 200 are mixed to form mixed water.

In this embodiment, the flow sensor 10 is disposed on at least one of the first water path 100 and the second water path 200. The temperature sensor 20 is disposed on at least one of the first waterway 100 and the second waterway 200. The ozone generating module 30 is disposed on at least one of the first waterway 100 and the second waterway 200. The ozone generating module 30 is used for mixing ozone into the water in the waterway.

The multifunctional waterway 1 provided by the embodiment is provided with the ozone generating module 30 in the waterway, and ozone is mixed into the water in the waterway by the ozone generating module 30, so that the mixed water in the first waterway 100 and the second waterway 200 is ozone water, pesticide residues can be removed when a user cleans fruits and vegetables by using the ozone water, and the ozone can be rapidly decomposed into oxygen after escaping, thereby not polluting the environment.

In addition, the multifunctional waterway 1 provided by the embodiment adjusts the ozone amount generated by the ozone generation module 30 by acquiring the flow and temperature of the first waterway 100 and/or the second waterway 200, so as to adjust the ozone concentration in the mixed water, and can realize the stability and effectiveness of the ozone concentration under different conditions by controlling the ozone generation module 30, thereby ensuring that the user obtains ozone water with proper concentration, and facilitating the removal of pesticide residues when the user washes fruits and vegetables.

In this embodiment, the flow sensor 10, the temperature sensor 20, and the ozone generation module 30 may be disposed on any one or two of the first water path 100 and the second water path 200, and the ozone amount generated by the ozone generation module 30 is adjusted by obtaining the flow and the temperature of the first water path 100 and/or the second water path 200, so as to adjust the ozone concentration in the mixed water, ensure that the user obtains ozone water with a proper concentration, and facilitate the user to remove pesticide residues when cleaning fruits and vegetables.

The first water path 100 and the second water path 200 have a flow path for flowing water, and may be a pipe or a duct structure, and the present application is not particularly limited. The water temperatures in the first water path 100 and the second water path 200 may be the same or different, and the present application is not particularly limited.

For example, in the washing machine, the first water path 100 may be a main water path, the second water path 200 is provided with the ozone generating module 30, and in the ozone washing mode, the second water path 200 is opened to form ozone water, and then the ozone water is mixed with the water in the first water path 100 to form mixed ozone water, so as to wash clothes, and at this time, the water in the first water path 100 and the second water path 200 may be cold water (tap water).

In this embodiment, to meet the requirement of the user for warm water, the temperature of the water in the second water path 200 is greater than that of the first water path 100. The mixed ozone water with the proper temperature is output by the second waterway 200 and the first waterway 100, so that the water demand of the user in the low-temperature environment can be met, and the multifunctional waterway 1 provided by the embodiment can ensure that the output warm water is at the proper ozone concentration, so that the requirement of the user for removing pesticide residues in the low-temperature environment (for example, in winter) can be met.

Wherein, the second water circuit 200 can be connected with a hot water supply device, such as: hot water output of water heaters (such as electric water heaters, gas water heaters, heat pump water heaters, solar water heaters). Of course, the multifunctional water circuit 1 may also be integrated into a hot water device, for example, the first water circuit 100 and the second water circuit 200 are located in a water heater, and the second water circuit 200 may be connected to a liner or a heat exchanger of the water heater. The first water path 100 and the second water path 200 may be mixed in the water heater for outputting water, or may be independently output in the water heater to form a cold water output and a hot water output, which is not particularly limited in the present application.

In order to prevent the ozone generating module 30 from scaling and to generate ozone water with the same concentration considering that the higher the water temperature is, the lower the solubility of ozone is, the ozone generating module 30 has a higher current or a higher dissolution pressure, so that the ozone generating module 30 has a higher requirement, and in order to reduce the requirement of the ozone generating module 30 and improve the service life of the ozone generating module 30, the water temperature in the water channel in which the ozone generating module 30 is located is below 50 ℃. In the case that the ozone generating module 30 is disposed in the second water path 200, the temperature of the water in the second water path 200 is not higher than 50 ℃.

In the embodiment of the present invention, the ozone generation module 30 can electrolyze water in the water path to generate ozone, and further mix ozone into water in the water path. The ozone generating module 30 can electrolyze water in a waterway to form ozone, and can form hydrogen in the water, and the hydrogen is harmless to human bodies, and directly escapes to the atmosphere after being output through water consumption points such as a water tap and the like, and does not pollute the environment.

Therefore, the ozone generating module 30 adopted in the present embodiment does not generate harmful gas in the process of forming ozone, so that no extra harmful gas treatment measures are required. In addition, the electrolytic ozone generation module 30 can directly form ozone in water, so that ozone can be directly dissolved in water without providing an air pipe or a high-pressure dissolution measure. Also, the ozone generating module 30 generates ozone formed by electrolyzing water in the flowing water, so that the ozone can be continuously dissolved into the water and the risk of ozone exceeding the standard is reduced.

In the embodiment of the present application, the ozone generating module 30 generates ozone when the flow rate of water in the water path is greater than zero. Preferably, the waterway in which the ozone generating module 30 is located is provided with a flow sensor 10, and the controller 40 controls the operation of the ozone generating module 30 according to a flow signal sent by the flow sensor 10. Of course, the ozone generation module 30 can also generate ozone when the flow rate of the water path is greater than the predetermined flow rate, so as to avoid the false opening. In the preferred embodiment, controller 40 controls ozone generation module 30 to generate ozone when flow sensor 10 detects a flow rate (flow rate greater than zero).

Specifically, the ozone generating module 30 includes a generating electrode located in the first water path 100 or the second water path 200, and a controller 40 connected to the generating electrode. The controller 40 can control the current or voltage supplied to the generating electrode. The ozone generating module 30 can be connected in series in the first water path 100 or the second water path 200, the generating electrodes include a cathode and an anode in the water, and correspondingly, the ozone generating module 30 can correspondingly form ozone and hydrogen at different electrodes.

In order to control the concentration of ozone in the mixed water, the controller 40 is connected to the flow sensor 10 and the temperature sensor 20, and the controller 40 controls the current or voltage supplied to the generating electrode according to the detection data of the flow sensor 10 and the temperature sensor 20. The controller 40 controls the amount of ozone through the current or voltage provided by the generating electrode, so as to control the concentration of ozone in the mixed water, and ensure that the ozone used by a user is in a safe and effective concentration range.

To ensure that the concentration of ozone in the mixed water is constant or within a predetermined concentration range, in one embodiment, the controller 40 decreases the current or voltage supplied to the generating electrode when the water temperature in the second water path 200 increases, in case the water temperature in the second water path 200 is within a predetermined temperature range. That is, when the water temperature of the second water path 200 is within the predetermined temperature range, the water temperature of the second water path 200 and the current or voltage supplied to the generating electrode have a negative correlation control relationship.

When the water temperature of the second water path 200 is raised, under the condition that the outlet water temperature and the outlet water flow are kept unchanged, the amount of hot water required to be mixed is reduced, correspondingly, the amount of cold water required to be mixed is increased, further, the flow of the first water path 100 is increased, the higher the flow rate of the first water path 100 is, the higher the ozone generation efficiency of the ozone generation module 30 is, and in order to maintain the stability of the ozone concentration, the current or voltage provided for the generation electrode can be reduced.

In this embodiment, in order to ensure that the concentration of ozone in the mixed water is in a constant state or in a predetermined concentration range, when the flow rate of the second water path 200 is within a predetermined flow rate interval, the controller 40 increases the current or voltage supplied to the generating electrode when the flow rate of the second water path 200 increases. That is, when the flow rate of the second water path 200 is within the predetermined flow rate interval, the flow rate of the second water path 200 has a positive correlation control relationship with the current or voltage supplied to the generating electrode.

When the flow rate of the second water path 200 is increased, the higher temperature of the outlet water required by the user is usually generated, at this time, the amount of hot water required to be mixed is increased, and when the flow rate of the outlet water is kept unchanged, the amount of cold water required to be mixed is correspondingly reduced, and further the flow rate of the first water path 100 is reduced, the lower the flow rate of the first water path 100 is, the lower the ozone generation efficiency of the ozone generation module 30 is, and the current or voltage supplied to the generation electrode can be increased in order to maintain the stability of the ozone concentration.

It should be noted that, in the control of the multifunctional water path 1 provided in the embodiment of the present application, the predetermined temperature interval and the predetermined flow rate interval only indicate that there is a certain interval (for example, the predetermined temperature interval is [30 ℃,75 ℃), the predetermined flow rate interval is [1L/min, 10L/min ]), the temperature and the flow rate of the second water path 200 and the current or the voltage supplied to the generating electrode are controlled in a negative correlation or a positive correlation, and the temperature or the flow rate outside the interval is not limited by the present application.

The controller 40 of the multifunctional water path 1 of the embodiment can control the amount of ozone formed by electrolysis of the generating electrodes by reducing or increasing the current or voltage supplied to the generating electrodes, thereby controlling the amount of ozone in water, so that under the condition that the temperature of hot water (water in the second water path 200) is increased or the flow rate is increased, in order to avoid the concentration of ozone in mixed water from being reduced, the current or voltage supplied to the generating electrodes is controlled, and the stability and effectiveness of the concentration of ozone under different conditions are realized.

In the embodiment of the present application, the ozone generating module 30 may be one, and is disposed in the first water path 100 or the second water path 200. Of course, in other embodiments, the ozone generating module 30 may be multiple and respectively disposed on the first water path 100 or the second water path 200, which is not limited in this application.

The temperature sensor 20 may be at least one, which may be a temperature probe. The temperature sensor 20 may be provided only in the first water passage 100 or only in the second water passage 200, and of course, both the first water passage 100 and the second water passage 200 may be provided with the temperature sensor 20. Similarly, the flow sensor 10 may be provided only in the first water path 100 or only in the second water path 200, similarly to the temperature sensor 20, and of course, the flow sensor 10 may be provided in both the first water path 100 and the second water path 200. To ensure the detection accuracy and avoid the influence of high temperature on the life of the flow sensor 10, the flow sensor 10 is preferably disposed in the first water path 100.

In the present embodiment, the temperature sensor 20 and the ozone generation module 30 are located in the same water circuit, that is, the temperature sensor 20 and the ozone generation module 30 are located in the first water circuit 100, or the temperature sensor 20 and the ozone generation module 30 are located in the second water circuit 200. Therefore, the temperature sensor 20 can detect the water temperature of the water channel where the ozone generating module 30 is located, so as to obtain the ozone generating water temperature, and further more accurately control the amount of ozone generated by the ozone generating module 30.

The multi-functional waterway 1 may further include a controller 40 connected to the at least one flow sensor 10, the at least one temperature sensor 20, and the ozone generating module 30. The controller 40 is configured to control the ozone concentration of the mixed water to be within a predetermined concentration range. The controller 40 may be integrated with the ozone generating module 30, or may be connected to the flow sensor 10, the temperature sensor 20 and the ozone generating module 30 through a wire 45, which is not particularly limited in the present application. The controller 40 may be connected to a power source 60 for supplying power thereto.

In this embodiment, the first water path 100 is provided with a temperature sensor 20, and/or the second water path 200 is provided with a temperature sensor 20. At least one of the first waterway 100 and the second waterway 200 is provided with a temperature sensor 20 so as to obtain the water temperature of at least one of the first waterway 100 and the second waterway 200, so that the ozone generating module 30 can adjust the amount of ozone formed. Preferably, the first waterway 100 and the second waterway 200 are both provided with temperature sensors 20. Therefore, the water temperature of ozone generation can be detected, the water channel environment where the ozone generation module 30 is located can be monitored, and the amount of ozone generated by the ozone generation module 30 can be controlled more accurately by the aid of the two paths of water temperatures.

In this embodiment, the first water path 100 is provided with a flow sensor 10, and/or the second water path 200 is provided with a flow sensor 10. At least one of the first and

second water paths

100 and 200 is provided with a flow sensor 10 to obtain a flow rate of at least one of the first and

second water paths

100 and 200 so that the ozone generating module 30 can adjust the amount of ozone formed. In the embodiment where the water temperature in the second water circuit 200 is higher than that in the first water circuit 100, the flow sensor 10 is preferably disposed in the first water circuit 100, so that a longer service life and accurate measurement data can be obtained, and an error or a shortened service life of the flow sensor 10 due to an excessively high water temperature can be avoided.

Further, one of the first water path 100 and the second water path 200 is provided with a flow sensor 10, a temperature sensor 20, and an ozone generating module 30; and a flow sensor 10 and/or a temperature sensor 20 are arranged on the other waterway. Further, a temperature sensor 20, a flow sensor 10 and an ozone generating module 30 are arranged on the first water path 100; a temperature sensor 20 is arranged on the second water path 200. The temperature sensor 20 may detect the temperature of the water in the waterway.

As shown in fig. 2, in one embodiment, a multifunctional waterway 1 is provided, which includes a first waterway 100 (which may be referred to as a cold water waterway) for flowing cold water and a second waterway 200 (which may be referred to as a hot water waterway) for flowing hot water. The first water path 100 is provided with an ozone generating module 30, a flow sensor 10a and a temperature sensor 20a (e.g., a temperature probe). The ozone generating module 30 serves to generate ozone and dissolve the ozone in water. The flow sensor 10a is used to detect a pipe flow of the first water circuit 100, and the temperature sensor 20a is used to detect a water temperature of the first water circuit 100. When the flow sensor 10a detects a flow signal of the first water circuit 100, the ozone generating module 30 is activated and generates ozone. The second water circuit 200 is also provided with a flow sensor 10b and a temperature sensor 20b for detecting the flow and the water temperature in the second water circuit 200.

In this embodiment, based on the flow rate and temperature detected by the flow sensor 10a and the temperature sensor 20a on the first water path 100 and the flow rate and temperature detected by the flow sensor 10b and the temperature sensor 20b on the second water path 200, and in combination with the target ozone concentration of the mixed water (water discharged from the faucet 50), the controller 40 calculates the current or voltage to be applied to the generating electrode of the ozone generating module 30, and feeds the current or voltage back to the ozone generating module 30, thereby outputting the required ozone concentration.

As shown in fig. 3, one possible embodiment provides a multi-functional waterway 1 including a first waterway 100 for flowing cold water and a second waterway 200 for flowing hot water. Wherein, the first water path 100 is provided with an ozone generating module 30, a flow sensor 10 and a temperature sensor 20. The ozone generating module 30 serves to generate ozone and dissolve the ozone in water. The flow sensor 10 is used for detecting the flow of water in the first water path 100, and the temperature sensor 20 is used for detecting the temperature of water in the first water path 100. When the flow sensor 10 detects a flow signal of the first water circuit 100, the ozone generating module 30 starts to generate ozone.

In this embodiment, the temperature (water temperature of the outlet water of the faucet 50) and the flow rate (for example, the flow rate is usually 5-7L/min, and the water temperature is 20-40 ℃ for the user) of the water used by the user can be set according to the empirical data. In this way, the temperature and flow rate of the water in the second water passage 200 are calculated from the set tap outlet water temperature and flow rate, and the water temperature and flow rate in the first water passage 100. Further, based on the flow rate and temperature detected by the flow rate sensor 10 and the temperature sensor 20 in the first water channel 100 and the calculated flow rate and temperature in the second water channel 200, and in combination with the target ozone concentration of the mixed water (tap water), the controller 40 calculates the current or voltage to be applied to the generating electrode of the ozone generating module 30, and feeds the current or voltage back to the ozone generating module 30, thereby outputting the required ozone concentration.

As shown in fig. 4, in one embodiment, a multi-functional waterway 1 is provided, which includes a first waterway 100 for flowing cold water and a second waterway 200 for flowing hot water. Wherein, the first water path 100 is provided with an ozone generating module 30, a flow sensor 10 and a temperature sensor 20 a. The ozone generating module 30 serves to generate ozone and dissolve the ozone in water. The flow sensor 10 is used to detect the flow rate of water in the first water path 100, and the temperature sensor 20a is used to detect the temperature of water in the first water path 100. When the flow sensor 10 detects that the first water circuit 100 has a flow signal, the ozone generating module 30 starts to generate ozone. A temperature sensor 20b is provided in the second water circuit 200 to detect the temperature of the water in the second water circuit 200.

In this embodiment, the temperature of the water used by the user can be set according to empirical data (for example, the temperature of the water used by the user is 20-40 degrees celsius). In this way, the flow rate of the hot water (the flow rate of the second water path 200) can be calculated from the water temperature of the first water path 100, the flow rate of the first water path 100, the water temperature of the second water path 200, and the set faucet outlet water temperature. According to the flow and temperature of the first water channel 100, the flow and temperature of the second water channel 200, and the target ozone concentration of the mixed water (tap water), the controller 40 calculates the current or voltage to be applied to the generating electrode of the ozone generating module 30, and feeds the current or voltage back to the ozone generating module 30, thereby outputting the required ozone concentration.

Of course, in this embodiment, the water flow rate of the user may also be set according to the empirical data (for example, the flow rate commonly used by the user is 5-7L/min). In this way, the flow rate of the hot water (the flow rate of the second water passage 200) can be calculated from the water temperature of the first water passage 100, the flow rate of the first water passage 100, the water temperature of the second water passage 200, and the set faucet output flow rate. According to the flow and temperature of the first water channel 100, the flow and temperature of the second water channel 200, and the target ozone concentration of the mixed water (tap water), the controller 40 calculates the current or voltage to be applied to the generating electrode of the ozone generating module 30, and feeds the current or voltage back to the ozone generating module 30, thereby outputting the required ozone concentration.

The ozone generating module 30 serves to generate ozone and dissolve the ozone in water. The flow sensor 10a is used to detect the flow rate of water in the first water path 100, and the temperature sensor 20 is used to detect the temperature of water in the first water path 100. When the flow sensor 10a detects a flow signal of the first water circuit 100, the ozone generating module 30 starts to generate ozone. A flow sensor 10b is provided in the second water circuit 200 for detecting the flow rate in the second water circuit 200.

In this way, the temperature of the hot water (the temperature of the second water channel 200) can be calculated from the temperature of the water in the first water channel 100, the flow rate of the second water channel 200, and the set tap outlet water temperature. According to the flow and temperature of the first water channel 100, the flow and temperature of the second water channel 200, and the target ozone concentration of the mixed water (tap water), the controller 40 calculates the current or voltage to be applied to the generating electrode of the ozone generating module 30, and feeds the current or voltage back to the ozone generating module 30, thereby outputting the required ozone concentration.
