The applicant has accordingly illustrated and described relevant background knowledge prior to describing embodiments of the present application to facilitate a clearer understanding and appreciation of the present application.

Ozone is an isomer of oxygen and is a strong oxidant, ozone can naturally decay into oxygen at room temperature, the decay period is 15 minutes to 25 minutes, ozone is quickly converted into ecological oxygen in water, the residual problem is avoided, ozone water damages chemical bonds of organic pesticides through strong oxidation, so that the ozone water loses the drug property, and meanwhile, various bacterial viruses on the surfaces of food materials are killed. The bacteria removing effect of ozone is 1.5 times of that of chlorine, and the sterilizing speed is 600-3000 times faster than that of chlorine.

Ozone is a pesticide residue removing bactericide with high efficiency and rapidness, can quickly dissolve pesticide residues in a short time, can effectively degrade pesticide residues in rice, vegetables and melons, can quickly kill bacteria and viruses, and prolongs the storage life. In addition, the ozone disinfection needs short time, no cleaning is needed after disinfection, no harmful residue and no secondary pollution are generated after ozone disinfection, the ozone is automatically decomposed into oxygen after disinfection, no peculiar smell and no pollution are generated, the disinfection is comprehensive, the effect is good, and the use cost is low.

Although ozone has the above advantages, it is very difficult to maintain proper and non-superscalar concentrations in water because ozone escapes from the water, especially considering that ozone reacts with almost any biological tissue as a strong oxidizer, it is more desirable to maintain ozone at proper non-superscalar concentrations in raw water.

Ozone is difficult to store, and can only be used along with production. The existing ozone generation mode is basically to convert part of oxygen in the air into ozone by utilizing the high-voltage ionization effect. The existing method for mixing ozone into water is basically to prepare ozone by high-pressure ionized air, and then send the ozone into water for dissolution through an air supply pipeline, which requires a special complicated air dissolution structure, high air dissolution pressure and the treatment problem of undissolved ozone. Considering the flow rate of water and the time required for dissolution, the current ozone concentration in the 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 currently use ozone for sterilization and disinfection, most of the products are mixed with ozone before heating, and the ozone in water basically escapes after the products are heated to high temperature, so that the output water basically loses the pesticide residue removing effect, and correspondingly, the products are mainly sterilized and disinfected by the ozone. Even if some products mix ozone into cold water to remove pesticide residues, further development is limited by the inability to control the ozone concentration in the output water to a suitable level.

The ozone concentration is understood to be the ozone content per volume of water. Ozone exists in the form of bubbles and/or dissolved in water.

As shown in fig. 1 to 5. In one embodiment of the present application, a multifunctional waterway 1 is provided, and the multifunctional waterway 1 may be integrated into water appliances such as a water heater, a faucet, a mixing valve 50, etc., and may be manufactured as a separate waterway module and used in waterways outside the water heater, the faucet, the mixing valve 50, etc., and the present application is not particularly limited.

Specifically, the multifunctional waterway 1 includes: first waterway 100, second waterway 200, flow sensor 10, temperature sensor 20, and ozone generating module 30. The water output by the first waterway 100 and the second waterway 200 is used for mixing to form mixed water.

In the present embodiment, the flow sensor 10 is disposed on at least one of the first waterway 100 and the second waterway 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 water in a waterway.

The multifunctional waterway 1 provided in this embodiment is configured with the ozone generating module 30 in the waterway, and ozone is mixed into water in the waterway by using the ozone generating module 30, so that the mixed water after 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 ozone can be rapidly decomposed into oxygen after escaping, thereby avoiding pollution to the environment.

In addition, in the multifunctional waterway 1 provided in this embodiment, the amount of ozone generated by the ozone generating module 30 is adjusted by obtaining the flow and the temperature of the first waterway 100 and/or the second waterway 200, so as to adjust the concentration of ozone in mixed water, and the ozone generating module 30 is controlled to realize the stability and the effectiveness of the concentration of ozone under different conditions, so that the user is ensured to obtain ozone water with proper concentration, and the user can conveniently remove pesticide residues when cleaning fruits and vegetables.

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

The first waterway 100 and the second waterway 200 have a flow path through which water flows, and may be a pipe or a tunnel 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.

The water channel where the ozone generating module 30 is located is an ozone generating water channel, and the output water is mixed with the water of another water channel for a user to use, for example, in a washing machine, the first water channel 100 may be a main water channel, the second water channel 200 is provided with the ozone generating module 30, in an ozone washing mode, the second water channel 200 is opened to form ozone water, and then the ozone water is mixed with the water of the first water channel 100 to form mixed ozone water, so as to clean clothes, and at this time, the water in the first water channel 100 and the second water channel 200 may be cold water (tap water).

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

Wherein the second waterway 200 may be connected to a hot water supply device, for example: hot water output of water heater (such as electric water heater, gas water heater, heat pump water heater, solar water heater). Of course, the multifunctional waterway 1 may be integrated in a water heating apparatus, for example, the first waterway 100 and the second waterway 200 are located in a water heater, and the second waterway 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 with water to be outputted from the water heater, or may be separately outputted from the water heater to form a cold water output end and a hot water output end, and the present application is not limited thereto.

In order to prevent the ozone generating module 30 from scaling, and to allow for the ozone water with the same concentration to be generated with the higher water temperature and the lower the solubility of ozone, the ozone generating module 30 needs to have a larger current or a larger 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, the service life of the ozone generating module 30 is prolonged, and the water temperature in the waterway where the ozone generating module 30 is located is below 50 ℃. In the case where the ozone generating module 30 is provided in the second waterway 200, the water temperature in the second waterway 200 is not higher than 50 degrees celsius.

In the embodiment of the present application, the ozone generating module 30 can generate ozone by hydrolyzing water in the water path, and further mix ozone into the water in the water path. The ozone generating module 30 can electrolyze water in a waterway to form ozone, and in addition, hydrogen is formed in the water, the hydrogen is not harmful to human body, and the hydrogen directly escapes into the atmosphere after being output by a water point such as a tap, and the environment is not polluted.

Therefore, the ozone generating module 30 used in the present embodiment does not generate harmful gas during the formation of ozone, so that no additional treatment for harmful gas is required. In addition, the electrolytic ozone generating module 30 can directly form ozone in water, so that the ozone can be directly dissolved in the water without providing an air supply pipe or high-pressure dissolution measures. Also, the ozone generating module 30 generates ozone in the water in a flowing state by electrolyzing the water, so that the ozone can be continuously dissolved into the water, and the risk of exceeding the ozone is reduced.

In an embodiment of the present application, ozone generation module 30 performs ozone generation when the flow rate of water in the waterway is greater than zero. Preferably, the water path where 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 transmitted from the flow sensor 10. Of course, the ozone generating module 30 may also generate ozone when the flow rate of the water path is greater than the predetermined flow rate, so as to avoid false opening. In a preferred embodiment, controller 40 controls ozone generating 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 waterway 100 or the second waterway 200, and a controller 40 connected to the generating electrode. The controller 40 is capable of controlling the current or voltage supplied to the generating electrode. The ozone generating module 30 may be connected in series in the first waterway 100 or the second waterway 200, the generating electrode includes a cathode and an anode positioned in water, and accordingly, the ozone generating module 30 may correspondingly form ozone and hydrogen at different electrodes.

In order to control the ozone concentration of 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 by the current or voltage supplied from the generating electrode, thereby controlling the concentration of ozone in the mixed water, and ensuring that the ozone used by the user is located 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 reduces the current or voltage supplied to the generating electrode when the water temperature of the second water path 200 is raised in the case that the water temperature of the second water path 200 is within a predetermined temperature interval. 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 is in negative correlation control with the current or voltage supplied to the generating electrode.

When the water temperature in the second water path 200 is raised, the amount of hot water to be mixed is reduced while the outlet water temperature and the flow rate are kept constant, and accordingly, the amount of cold water to be mixed is increased, and the flow rate of the first water path 100 is increased, and the higher the flow rate of the first water path 100, the higher the ozone generation efficiency of the ozone generating module 30 is, and the current or voltage to be supplied to the generating electrode can be reduced in order to maintain the stability of the ozone concentration.

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, the controller 40 increases the current or voltage supplied to the generating electrode when the flow rate of the second waterway 200 is increased in a predetermined flow rate interval. That is, when the flow rate of the second water channel 200 is within the predetermined flow rate interval, the flow rate of the second water channel 200 is in positive correlation control with the current or voltage supplied to the generating electrode.

When the flow rate of the second water path 200 increases, the amount of hot water mixed in is increased, and when the flow rate of the water is kept constant, the amount of cold water mixed in is reduced, and the flow rate of the first water path 100 is reduced, so that the ozone generating efficiency of the ozone generating module 30 is reduced as the flow rate of the first water path 100 is reduced, and the current or voltage supplied to the generating electrode can be increased to maintain the stability of the ozone concentration.

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

The controller 40 of the multifunctional waterway 1 of the present embodiment can control the amount of ozone formed by electrolysis of the generating electrode by reducing or increasing the current or voltage supplied to the generating electrode, thereby controlling the amount of ozone in water, so that in the case of water temperature increase or flow rate increase of hot water (water in the second waterway 200), in order to avoid concentration decrease of ozone in mixed water, stability and effectiveness of ozone concentration under different conditions are achieved by controlling the current or voltage supplied to the generating electrode.

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

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 channel 100 or only in the second water channel 200, and of course, the temperature sensor 20 may be provided in both the first water channel 100 and the second water channel 200. The flow sensor 10 is also at least one, and similar to the temperature sensor 20, it may be provided only in the first water path 100 or only in the second water path 200, 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 detection accuracy and avoid high temperature affecting the lifetime of the flow sensor 10, the flow sensor 10 is preferably disposed in the first waterway 100.

In the present embodiment, the temperature sensor 20 and the ozone generating module 30 are located in the same waterway, i.e., the temperature sensor 20 and the ozone generating module 30 are located in the first waterway 100, or the temperature sensor 20 and the ozone generating module 30 are located in the second waterway 200. Thus, the temperature sensor 20 can detect the water temperature of the waterway where the ozone generating module 30 is located, and the ozone generating water temperature is obtained, so that the amount of ozone generated by the ozone generating module 30 can be better and more accurately controlled.

The multi-functional waterway 1 may further include a controller 40 coupled 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 locate the ozone concentration of the mixed water 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 the wires 45, and the present application is not limited thereto. The controller 40 may have a power supply 60 connected thereto for supplying power.

In this embodiment, the first waterway 100 is provided with a temperature sensor 20, and/or the second waterway 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 that the water temperature of at least one of the first waterway 100 and the second waterway 200 is obtained, 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 each provided with a temperature sensor 20. Thus, not only can the ozone generating water temperature be detected and the waterway environment of the ozone generating module 30 be monitored, but also the two-way water temperature can more accurately control the amount of ozone generated by the ozone generating module 30.

In this embodiment, the first waterway 100 is provided with a flow sensor 10, and/or the second waterway 200 is provided with a flow sensor 10. At least one of the first waterway 100 and the second waterway 200 is provided with a flow sensor 10 to obtain a flow rate of at least one of the first waterway 100 and the second waterway 200 so that the ozone generating module 30 adjusts an amount of ozone formed. In the embodiment of the first waterway 100 with water Wen Dayu in the second waterway 200, the flow sensor 10 is preferably disposed in the first waterway 100, so that a longer service life and accurate measurement data can be obtained, and errors or shortened service life of the flow sensor 10 due to too high water temperature can be avoided.

Further, one of the first waterway 100 and the second waterway 200 is provided with a flow sensor 10, a temperature sensor 20, and an ozone generating module 30; the other waterway is provided with a flow sensor 10 and/or a temperature sensor 20.

The temperature sensor 20 may detect the water temperature of the waterway in which it is located.

As shown in fig. 2, in one embodiment, a multi-functional waterway 1 is provided, including a first waterway 100 (which may be referred to as a cold water waterway) through which cold water flows and a second waterway 200 (which may be referred to as a hot water waterway) through which hot water flows. The first waterway 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 is used to generate ozone and dissolve the ozone in water. The flow sensor 10a is used for detecting the pipe flow of the first water path 100, and the temperature sensor 20a is used for detecting the water temperature of the first water path 100. When the flow sensor 10a detects that the first waterway 100 has a flow signal, the ozone generating module 30 is activated and generates ozone. The second waterway 200 is also provided with a flow sensor 10b and a temperature sensor 20b for detecting the flow rate and the water temperature on the second waterway 200.

In this embodiment, based on the flow rate and temperature detected by the flow rate sensor 10a and the temperature sensor 20a on the first waterway 100 and the flow rate and temperature detected by the flow rate sensor 10b and the temperature sensor 20b on the second waterway 200, in combination with the target ozone concentration of the mixed water (the 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 back to the ozone generating module 30, thereby achieving the output of the required ozone concentration.

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

In this embodiment, the user's water temperature (faucet 50 outlet water temperature) and flow rate (e.g., the user's usual flow rate is 5-7L/min, water temperature is 20-40 degrees Celsius) may be set based on empirical data. In this way, the water temperature and flow rate of the second waterway 200 are calculated from the set water temperature and flow rate of the tap water, the water temperature of the first waterway 100, and the flow rate. Further, based on the flow rate and temperature detected by the flow rate sensor 10 and the temperature sensor 20 in the first waterway 100 and the calculated flow rate and temperature in the second waterway 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 back the current or voltage to the ozone generating module 30, thereby realizing the output of the required ozone concentration.

A temperature sensor 20b is provided in the second water path 200 for detecting the temperature of water in the second water path 200.

In this embodiment, the user's water temperature may be set based on empirical data (e.g., the user's water temperature is typically 20-40 degrees celsius). In this way, the flow rate of the hot water (the flow rate of the second waterway 200) can be calculated from the water temperature of the first waterway 100, the flow rate of the first waterway 100, the water temperature of the second waterway 200, and the set tap outlet water temperature. Based on the flow rate and temperature of the first waterway 100, the flow rate and temperature of the second waterway 200, and the target ozone concentration of the mixed water (tap water), the controller 40 calculates the current or voltage required to be applied to the generating electrode of the ozone generating module 30, and feeds back to the ozone generating module 30, thereby achieving the output of the required ozone concentration.

Of course, in this embodiment, the user's water flow rate may also be set based on empirical data (e.g., the user's usual flow rate is 5-7L/min). In this way, the flow rate of the hot water (the flow rate of the second water channel 200) can be calculated from the water temperature of the first water channel 100, the flow rate of the first water channel 100, the water temperature of the second water channel 200, and the set tap output flow rate. Based on the flow rate and temperature of the first waterway 100, the flow rate and temperature of the second waterway 200, and the target ozone concentration of the mixed water (tap water), the controller 40 calculates the current or voltage required to be applied to the generating electrode of the ozone generating module 30, and feeds back to the ozone generating module 30, thereby achieving the output of the required ozone concentration.

As shown in fig. 5, a multi-functional waterway 1 is provided in one possible embodiment, including a first waterway 100 for flowing cold water and a second waterway 200 for flowing hot water. The first waterway 100 is provided with an ozone generating module 30, a flow sensor 10a, and a temperature sensor 20. The ozone generating module 30 is used to generate ozone and dissolve ozone in water, the flow sensor 10a is used to detect the flow of the pipeline, and the temperature sensor 20 is used to detect the water temperature on the cold water pipeline. The ozone generating module 30 is used 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 waterway 100, and the temperature sensor 20 head is used to detect the water temperature of the first waterway 100. When the flow sensor 10a detects that the first waterway 100 has a flow signal, the ozone generating module 30 is activated to generate ozone. The second waterway 200 is provided therein with a flow sensor 10b for detecting a flow rate in the second waterway 200.

In this embodiment, the user's water temperature may be set based on empirical data (e.g., the user's water temperature is typically 20-40 degrees celsius). In this way, the water temperature of the hot water (the water temperature of the second waterway 200) can be calculated from the water temperature of the first waterway 100, the flow rate of the second waterway 200, and the set tap water outlet water temperature. Based on the flow rate and temperature of the first waterway 100, the flow rate and temperature of the second waterway 200, and the target ozone concentration of the mixed water (tap water), the controller 40 calculates the current or voltage required to be applied to the generating electrode of the ozone generating module 30, and feeds back to the ozone generating module 30, thereby achieving the output of the required ozone concentration.

In other embodiments, in a scenario where there is a trunk road upstream or downstream of the first waterway 100 and the second waterway 200 (the first waterway 100 and the second waterway 200 are two branches after the trunk road is split, or the first waterway 100 and the second waterway 200 are combined to form the trunk road), the flow or the temperature can be measured on the trunk road, and the controller 40 can regulate and control the ozone concentration of the mixed water more accurately according to the measured data and combine the measured data of the first waterway 100 and the second waterway 200, so as to ensure that the user obtains the ozone water with constant ozone concentration.

In the embodiment of the application, the multifunctional waterway 1 can be integrated in water equipment or water heating equipment, and can be installed in a water delivery waterway, for example, the multifunctional waterway 1 can be integrated in a mixing faucet or a water heater, and can be also arranged in the water delivery waterway between the faucet and the water heater.

In a specific embodiment, to enhance the scene adaptation capability of the multifunctional waterway 1, the multifunctional waterway 1 includes a housing, and a first input interface, a second input interface, a first output interface, and a second output interface on the housing. The multifunctional waterway 1 forms a waterway module with four interfaces, and can be directly installed on the occasion of the required ozone water to meet the ozone water requirement of users.

In this embodiment, the first waterway 100 includes a first conduit in the housing connecting a first input interface and a first output interface. The second waterway 200 includes a second tube in the housing connecting a second input interface and a second output interface. At least one flow sensor 10, at least one temperature sensor 20, and an ozone generating module 30 are provided to the housing. The exposure of the flow sensor 10, the temperature sensor 20, and the ozone generating module 30 to the air can be avoided by providing a housing. The at least one flow sensor 10, the at least one temperature sensor 20, and the ozone generating module 30 share the same housing, and may be fixed to the inside of the housing or may be fixed to a wall of the housing, and the present application is not limited only.

The second waterway 200 is used for connecting a hot water interface of the mixing valve 50. The mixing valve 50 may include a faucet or a shower. When the multifunctional waterway 1 is applied, the ozone function can be realized without damaging the waterway structure of a user, for example, when the multifunctional waterway 1 is connected between a tap and a water heater, the multifunctional waterway 1 can be connected between a cold water valve, a hot water valve and the tap, and the original waterway does not need to be changed, so that the multifunctional waterway has better scene adaptation capability.

Based on the same concept, the present invention also provides a mixing valve 50, as described in the following embodiments. Because the principle of the water mixing valve 50 for solving the problems and the technical effects that can be achieved are similar to those of the multifunctional waterway 1, the implementation of the water mixing valve 50 can be referred to the implementation of the multifunctional waterway 1, and the repeated parts are not repeated.

The embodiment of the application also provides a water mixing valve 50, which comprises a water outlet end, a water mixing structure connected with the water outlet end, a cold water interface and a hot water interface. The cold water interface is communicated with the water mixing structure through a first waterway 100; the hot water interface is communicated with the water mixing structure through a second waterway 200.

Wherein, the mixing valve 50 further comprises: a flow sensor 10; a temperature sensor 20; ozone generating module 30. The flow sensor 10 is disposed on at least one of the first waterway 100 and the second waterway 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 water mixing structure may be a three-way structure, or a valve body structure having a valve element, and the water mixing valve 50 may be configured to adjust the mixing ratio of cold water and hot water, or may be configured to mix only cold water and hot water.

In this embodiment, the multifunctional waterway 1 is integrated in an internal waterway of the mixing valve 50, and in other embodiments, the multifunctional waterway 1 may also be disposed in an external waterway of the mixing valve 50, which will not be described herein.
