Description

Water purification and quality assurance system

Technical field

The invention particularly relates to a water purification and quality assurance system.

Background technique

The existing water purification system includes a raw water supply unit, a raw water purification unit, a water gas mixer, a booster pump, a water purification tower, a direct drinking water machine, an ozone generator and an air pump, wherein the direct drinking water machine is provided with a hot biliary and a faucet assembly. The faucet assembly comprises a cold water tap and a hot water tap. The water purification tower comprises a water purification tower body. The water purification tower body is provided with a water inlet and a water outlet, and the water inlet of the water purification tower is connected with the water outlet of the booster pump. The raw water supply unit communicates with the water inlet end of the water gas mixer through the raw water purification unit, the air pump is in communication with the intake end of the ozone generator, and the output end of the ozone generator is connected to the intake end of the water gas mixer, the water The water outlet of the gas mixer is in communication with the water inlet of the booster pump.

The raw water supply unit provides raw water that does not meet the drinking water standard, and after being purified by the raw water purification unit, the ozone water is mixed by the water gas mixer to output the ozone water to the water purification tower. The water stored in the water purification tower enters the water tank in the drinking water machine through the pipeline, and the water in the water tank is heated on the one hand and hot water is supplied through the hot water tap. The water in the water tank on the other hand provides normal temperature water through the cold water tap.

Existing water purification systems have the following disadvantages:

First, in order to adjust the pressure balance between the inside and outside of the water purification tower, a siphon opening is opened at the top of the body of the water purification tower. In the prior art, the siphon mouth directly communicates with the outside world, so bacteria, viruses, impurities, etc. in the outside air easily enter the water purification tower body through the siphon mouth, thereby polluting the purified water stored in the water purification tower body, endangering human health. . At the same time, since the body of the water purification tower is easily contaminated, it is necessary to regularly clean and disinfect the body of the water purification tower, thereby increasing the use and maintenance cost, and there are residual disinfectants, which further endanger human health.

Second, the water intake terminal drinking water machine adopts the water tank water supply mode, and the water tank water supply mode has the following disadvantages:

1. The water stored in the water tank cannot be recycled to the direct drinking water for circulation in the pipeline network and returned to the main machine for reactivation and disinfection. This part of the water will be aged or aged due to long-term storage in the water tank, affecting the water quality.

2, because the water tank in and out of the water must use the principle of siphon, so each time you take water, there will be a corresponding amount of air in the installed environment into the water tank, resulting in dust, microbial spores, pathogenic bacteria, etc. in the air of the installation environment into the water tank mixed into the water, will Cause secondary pollution of drinking water.

3, the water tank and the water parts will be polluted for a long time, it needs to be cleaned regularly, it takes a lot of labor and cleaning disinfectant, and the disinfectant will remain on the water tank and water parts when cleaning, polluting water quality ,Harmful to health.

4. Due to the water supply of the water tank, the water intake end of the direct drinking water machine uses the natural pressure siphon principle of the atmosphere to take water, and the water output is small.

Thirdly, the faucet assembly comprises a water outlet nozzle, wherein the water outlet nozzle is cylindrical, half of the water outlet of the cold water tap and half of the water outlet of the hot water tap are connected to the outside through the water outlet nozzle, and finally the cold water and the hot water flow out through the water outlet nozzle. Since the outlet pipe diameter is large, the actual water outlet of the cold water tap and the hot water tap has only half of the water outlet area, so the water flow from the cold water tap and the hot water tap is small, the flow rate is slow, and the water pressure is small. The effect of flushing the inner wall of the spout is not enough, so that the bacteria on the inner wall of the spout cannot be washed away, resulting in pollution of drinking water. At the same time, the outlet nozzle and the faucet assembly are integrally connected, which is inconvenient to clean.

Fourth, the water-gas mixer is susceptible to ozone corrosion and backwater, so that the ozone generator does not generate ozone and corrode the ozone generator when it encounters water, loses the function of sterilizing and disinfecting water by using ozone, has low work reliability, and endangers human health. Increased use and maintenance costs and low operational reliability.

In short, in the existing water purification system, the purified water can not be circulated, is easily polluted by secondary pollution, cannot be supplemented with oxygen as needed, and has low quality.

The direct drinking water machine 1900 includes a first three-way joint 1201, a faucet assembly 9 and a hot blast assembly 11, the faucet assembly 9 including a cold water tap 901 and a hot water tap 902, the hot bile assembly 11 including a hot bladder 1101, a first three-way The first end of the joint 1201 is for communicating with the water supply end of the direct drinking water supply pipe network, and the second end of the first three-way joint 1201 is for communicating with the water-removing end of the direct drinking water supply pipe network, and includes The one-way valve 1111; the third end of the first three-way joint 1201 is in communication with the inlet of the water supply line of the direct drinking water machine 1900, and the water inlet of the cold water tap 901 and the water inlet of the hot bladder 1101 are both connected with the water supply line outlet of the drinking water machine 1900. The hot water 1101 water outlet is in communication with the hot water tap 902 inlet; the steam outlet of the hot bladder 1101 is in communication with the inlet of the check valve 1111, and the outlet of the check valve 1111 is in communication with the outside. The hot bladder 1101 is wrapped with an insulating material.

Since the one-way valve 1111 is provided (the one-way valve 1111 only allows the steam in the hot rib 1101 to be discharged through the one-way valve 1111, the outside air is not allowed to enter the hot biliary), when the hot jerk 1101 is heated, the pressure of the water vapor will The one-way valve 1111 is opened, at which time water vapor is discharged through the one-way valve 1111 (can be discharged to the waste water tank of the direct drinking water machine 1900, etc.); when the hot bladder 1101 is not heated, the one-way valve 1111 is not under pressure and is closed. status. It can be seen that in the present invention, the steam outlet of the hot bladder 1101 does not need to be connected to the water tank, and does not heat the direct drinking water and cold water, and does not affect the access effect of the direct drinking water and cold water, and does not have any influence on the water experience.

Direct drinking water supply pipe network directly through the first three-way joint 1201 and the direct drinking water machine 1900 water supply line directly provide cold drinking water for the cold water tap 901 and hot galley 1101, avoiding the use of water tank water supply. The direct drinking water supply pipe network not only provides the direct drinking water to the direct drinking water machine 1900, but also does not affect the direct drinking water supply pipe network to the normal water supply and normal drinking water. The direct drinking water machine 1900 is equivalent to direct drinking water for delivery. The “one pipe” of the pipe network is called “pipe overcurrent”. Since the water tank water supply mode is not used in the direct drinking water machine 1900, the invention overcomes the secondary pollution existing in the traditional water tank water supply mode drinking water machine, the water quality aging, the cleaning and disinfection labor cost, the cleaning disinfectant cost large, the cleaning disinfectant Residual problem. At the same time, since the water is not required to be taken through the siphon principle of the water tank, it is directly taken through the water supply pipe of the water supply pipe, and the water output is large.

The first three-way joint 1201 is a mountain-shaped three-way joint, and the middle end of the mountain-shaped three-way joint is a third end of the first three-way joint 1201. Since the third end of the first three-way joint 1201 is installed on the upper end, if the water supply of the direct drinking water machine 1900 is not used for a long time, when the direct drinking water is supplied to the water channel in the conveying pipe network, even if the drinking water machine 1900 does not take water for a long time, the first three-way joint 1201 The water in the third end will also be brought into the drinking water network for the drinking water to participate in the circulating flow to avoid the generation of stagnant water.

The faucet assembly 9 further includes a funnel-shaped spout 912. The upper portion of the funnel-shaped spout 912 and the cold water faucet 901 and the hot water faucet 902 enclose a closed cavity 9121, the water outlet of the cold water tap 901 and the hot water tap 902. Both are in communication with the cavity 9121, and the cavity 9121 communicates with the outside through a water outlet pipe 9122 at the lower portion of the funnel-shaped water outlet 912.

The water outlets of the cold water tap 901 and the hot water tap 902 are both round holes, and the water outlet pipe 9122 has a circular cross section. This structure is advantageous for production and assembly.

The cold water tap 901 and the hot water tap 902 are detachably connected to the water outlet 912 for easy disassembly and assembly.

The direct drinking water machine 1900 further includes a second three-way joint 903, the first end and the second end of the second three-way joint 903 are straight-through ends, and the third end of the second three-way joint 903 is a bypass end, the second The first end of the three-way joint 903 is connected to the water supply line outlet of the direct drinking water machine 1900, the second end of the second three-way joint 903 is connected to the water inlet of the cold water tap 901, and the third end of the second three-way joint 903 is connected with the hot bladder. The 1101 inlet is connected.

With the above structure, even if the cold water tap 901 is not used for long-term use of water, when the hot water is connected, since the extension water supply line communicates with the first end of the second three-way joint 903, the water in the extension water supply line passes through the second. The first end and the third end of the three-way joint 903 flow into the hot die 1011; meanwhile, since the first end and the second end of the second three-way joint 903 are straight-through ends, the impact of the water flow in the water supply line of the extension will The water at the second end of the second three-way joint 903 and the water inlet of the cold water tap 901 is taken away through the third end of the second three-way joint 903 and replenished in time to avoid the water supply between the extension water supply line and the water inlet of the cold water tap 901. The water in the pipeline is aged to prevent bacterial growth.

The second end of the second three-way joint 903 š has a length of 0 to 5 cm. After testing, the second end of the second three-way joint 903 is too long, which is not conducive to the flow of water; the second end of the second three-way joint 903 is too short, which is not conducive to production and disassembly, the second three-way The second end of the joint 903 has a length of 0 to 5 cm.

The first end of the second three-way joint 903 is detachably connected to the water supply line outlet of the direct drinking water machine 1900, and the second end of the second three-way joint 903 is fixedly connected with the water inlet of the cold water tap 901, and the second three-way The third end of the joint 903 is for detachable connection with the hot biliary water inlet.

An inflatable bladder 1102 is also coupled between the steam outlet of the hot die 1101 and the inlet of the check valve 1111. The air bag 1102 is jacketed with a protective cover to prevent the air bag 1102 from bursting during inflation.

Since the expandable and contractible airbag 1102 is provided, when the hot bladder 1101 is heated, the water vapor first enters the airbag 1102 through the steam outlet, and at this time, the airbag 1102 expands, and when the steam amount is too large, it is discharged through the check valve 1111; When the bladder 1101 is not heated, the water vapor is liquefied into water and stored in the airbag 1102, at which time the airbag 1102 contracts. This will avoid excessive water vapor.

The air bag 1102 is made of a silicone material, and the air bag 1102 is connected to the steam outlet of the hot jewel 1101 through a rigid tube 1103; the air bag 1102 and the rigid tube 1103 are vertically disposed above the hot sill 1101. Since the airbag 1102 is made of a silicone material, it has a certain hardness and deformation ability. The airbag 1102 and the hard straight tube 1103 are vertically disposed above the hot bladder 1101, so that the liquid water in the airbag 1102 can be returned to the hot bladder 1101 for reuse.

The drinking water machine 1900 further includes a water level detector 1104 and a water inlet solenoid valve 907 disposed on the water supply line of the direct drinking water machine 1900. The water level detector 1104 includes a grounded common electrode 11043 for detecting whether the water level in the hot bladder 1101 exceeds The water inlet electrode 11041 of the water inlet position, the full water electrode 11042 for detecting whether the water level in the hot bladder 1101 exceeds the full water level; the water inlet electrode 11041 is electrically connected to the water inlet detecting end of the controller 10 through the first voltage dividing resistor 1109, The full water electrode 11042 is electrically connected to the full water detecting end of the controller 10 through the second voltage dividing resistor 1110, and the water inlet detecting end and the full water detecting end are both pulse switchable I/O ports and A/D detecting ports. a multiplexing end; a first voltage dividing resistor 1109 and a water detecting end, a second voltage dividing resistor 1110 and a full water detecting end are electrically connected to the power source positive electrode; the controller 10 passes the water inlet solenoid valve driving circuit 906 and The control end of the water inlet solenoid valve 907 is electrically connected.

The water inlet detecting end and the full water detecting end of the controller 10 are both I/O ports in a normal state, and the water inlet detecting end and the full water detecting end of the controller 10 are A/D detecting ports when the water level is detected by the pulse. In the normal state, the influent detecting end and the full water detecting end are input to the controller 10 in a sinking state, and the voltage on the influent electrode 11041 and the full water electrode 11042 is zero volt, and water is not electrolyzed. By detecting the water level by pulse, the detection time is extremely short, so the electrolysis time is extremely short, and the influence is basically negligible. Therefore, when the water level exceeds the water level, the common electrode 11043 and the water inlet electrode 11041 are always connected into an electrolytic circuit to continuously perform electrolysis, thereby avoiding electrolysis to produce substances harmful to the human body. When the controller 10 detects that the water level in the hot bladder 1101 is lower than the water level, the controller 10 drives the water inlet solenoid valve 907 to open by the water inlet solenoid valve driving circuit 906, and the drinking water enters the hot bladder 1101; when the controller 10 detects When the water level in the hot bladder 1101 is higher than the full water level, the controller 10 closes the water inlet solenoid valve 907 through the water inlet solenoid valve drive circuit 906, and the direct drinking water cannot enter the hot bladder 1101.

The terminals of the common electrode 11043, the water inlet electrode 11041 and the full water electrode 11042 are fixed on the hard tube 1103.

The controller 10 is an STC12C5404AD chip and its peripheral circuits.

a first normally open reed switch 904 is disposed in the cold water tap 901, and a cold magnet control handle 9011 of the cold water tap 901 is provided with a first magnet 905 that cooperates with the first normally open reed switch 904; the first normally open type The first contact of the reed switch 904 is grounded, the second contact of the first normally open reed switch 904 is electrically connected to the controller 10, and the output of the controller 10 is connected to the straight through the water inlet solenoid valve drive circuit 906. The control end of the water inlet solenoid valve 907 on the water supply line of the drinking water machine 1900 is electrically connected; when the cold water is connected, the cold water control handle 9011 drives the first magnet 905 to move and the first normally open type reed switch 904 is located at the first magnet 905. Within the magnetic field.

A second normally open reed switch 908 is disposed in the hot water tap 902. The hot water control handle 9021 of the hot water tap 902 is provided with a second magnet 909 that cooperates with the second normally open reed switch 908; the second normally open The first contact of the type reed switch 908 is grounded, the second contact of the second normally open reed switch 908 is electrically connected to the controller 10, and the output of the controller 10 is connected to the water supply solenoid valve drive circuit 906. The control end of the water inlet solenoid valve 907 on the drinking water machine 1900 water supply line is electrically connected; when the hot water is connected, the hot water control handle 9021 drives the second magnet 909 to move and the second normally open type reed switch 908 is located in the second The magnetic field of the magnet 909 is within the range.

With the above configuration, the water inlet solenoid valve 907 is in a closed state in a normal state. When it is necessary to take cold water, the cold water control handle 9011 drives the first magnet 905 to move and causes the first normally open reed switch 904 to be located within the magnetic field of the first magnet 905, at which time the first normally open reed switch 904 One contact and the second contact are in communication, and after the controller 10 detects the state, the water inlet solenoid valve 907 is driven to open by the water inlet solenoid valve driving circuit 906, and the water in the extension water supply line flows out through the cold water tap 901. The hot water intake process is similar to the cold water intake process. Since the water inlet solenoid valve 907 is in a closed state when water is not taken, the water vapor in the heat jerk 1101 can be prevented from heating the water in the extension water supply line, thereby affecting the cold water intake effect.

A temperature sensor 1105 and a heating element 1106 are disposed in the hot die 1101. The temperature sensor 1105 is electrically connected to an input end of the controller 10 through an A/D converter 1107, and an output end of the controller 10 passes through a heating element driving circuit 1108. It is electrically connected to the heating member 1106.

With the above configuration, a suitable hot-boil water supply temperature is set in advance in the controller 10. When the hot die 1101 is in operation, the water in the hot bladder 1101 is heated by the heating member 1106, and the temperature sensor 11058 detects the water temperature in the hot bladder 1101 and sends it to the controller 10, and the controller 10 detects the detected hot bile water temperature and the set heat. The bile water supply temperature is compared. When the detected hot bile water temperature reaches the hot bile water supply temperature, the controller 10 controls the heating member 1106 to stop working by the heating member driving circuit 1108.

The temperature sensor 1105 is a temperature sensitive resistor. The heating element 1106 is a heating wire.

The third end of the first three-way joint 1201 is connected to the water supply line of the direct drinking water machine 1900 through the extension main valve 1202. The extension valve 1202 can be used to brake water and adjust the amount of water.

The components of the direct drinking water machine 1900 are installed in the extension housing 1204. The extension housing 1204 is provided with a detachable front panel 1205. The outlet of the one-way valve 1111 communicates with the waste water tank 1203 on the front panel 1205. The adjustment handle of the extension master valve 1202 extends from the side panel of the extension housing 1204. The faucet assembly 9 is exposed through the front panel 1205. The bottom surface of the water leakage protection screen 1206 is insulated from the extension housing 1204.

A water leakage protection sheet 1207 is further disposed in the bottom of the extension housing 1204, and the water leakage protection sheet 1207 is electrically connected to the controller 10 through the water leakage protection sensing circuit 1207.

In the direct drinking water machine 1900, the water level detection logic in the hot bladder 1101 is as follows:

1. The direct drinking water machine 1900 is in a standby state every time the power is turned on. At this time, the full water detecting end and the influent detecting end connected to the full water electrode 11042 and the water inlet electrode 11041 of the controller 10 are in the normal I/. The input mode of the O port, the full water detecting end and the influent detecting end are input into the controller 10 in the form of sinking current, and the voltage on the full water electrode 11042 and the influent electrode 11041 is zero volt. In fact, the hot swell 1101 is no longer or lower than this time. Into the water level, there will be no ionized water.

2. When the direct drinking water machine 1900 is pressed or turned on, there is water or no water, and the full water detecting end and the influent detecting end connected to the full water electrode 11042 and the water inlet electrode 11041 of the controller 10 are used by ordinary I/O. The port input mode is changed to the A/D detection input state. At this time, the voltages on the full water electrode 11042 and the water inlet electrode 11041 are different due to different resistance values: 1 such as between the full water electrode 11042 or the water inlet electrode 11041 and the common electrode 11043. When there is water, the voltage at the detection end of the full water and the detection end of the water is about 2 to 3V (the water quality is different, the heating wire is different, the voltage will change), and the hot bladder 1101 does not need to enter the water. This operation only needs one time. Detecting once every 0.05 seconds stops; 2 If there is no water between the full water electrode 11042 or the water inlet electrode 11041 and the common electrode 11043, the voltage at the full water detection end and the water inlet detection terminal is about 5V. The water solenoid valve 907 is filled with water, and a pulse detection signal is generated once every 5 seconds, and the length of each inspection is 0.05 seconds. Since the influent and the effluent are simultaneously performed, the electrode of the water level detector 1104 is not in the water, but the water is flowing, and the water containing the contact electrode has flowed away without having to be electrolyzed, so the electrolysis problem is negligible.

The drinking water machine 1900 is not subjected to hot water operation in the daily work, and the water level detector 1104 does not detect, the hot water operation occurs, and the water level detector 1104 detection mode is consistent with the 2-2 mode.

3, direct drinking water machine 1900 each time press the heating button switch or automatically start heating, the controller 10 will replace the full water detection end and the influent detection end from the ordinary I / O port input form into A / D detection input form, detection Whether the hot bladder 1101 needs to enter the water, that is, whether the water level is lower than the water inlet level, each time the heating button switch operation is performed and the heating action is automatically started, only one detection occurs, and the time is 0.05 seconds each time. This kind of related functional startup is a normally closed detection method for water level detection, which greatly reduces the frequency and time of water level detection. It is especially suitable for liquid level detection which is easy to be detected by the electrolyte body to avoid liquid electrolysis of the detected liquid level and affect the liquid. The quality is especially suitable for the liquid level detection by sending a liquid signal through the wired or wireless signal and opening the working mode of the liquid outlet valve.

In the direct drinking water machine 1900, the hot water 1101 water level control process is as follows:

When the drinking water machine 1900 is powered on, the water level detector 1104 automatically detects whether there is water in the hot bladder 1101, and the state of the water level, and determines whether the hot bladder 1101 automatically enters the water, and is divided into the following cases:

1. The direct drinking water machine 1900 is turned on, and when the hot squid 1101 is dry, the water inlet solenoid valve 907 is automatically opened, and the hot bristles 1101 automatically enters the water.

2. The drinking water machine 1900 is turned on, and the water level detector 1104 detects that there is water in the hot shovel 1101, but when the water level does not reach the water level of the inlet electrode 11041, the water inlet solenoid valve 907 is triggered to open, and the hot shovel 1101 enters the water; when the water level reaches When the water electrode 11042 is at the water level, the water inlet solenoid valve 907 is closed to stop the water inlet.

3. The drinking water machine 1900 is turned on, and the water level detector 1104 detects that there is water in the hot rib 1101. When the water level reaches the water level of the water inlet electrode 11041 and does not exceed the water level of the full water electrode 11042, the water inlet solenoid valve 907 does not open, and the hot broth 1101 Do not enter the water.

4. The drinking water machine 1900 is turned on, and the water level detector 1104 detects that there is water in the hot rib 1101. When the water level reaches the water level of the full water electrode 11042, the water inlet solenoid valve 907 does not open, and the hot stalk 1101 does not enter the water.

5. The drinking water machine 1900 is turned on, and the water level detector 1104 detects that there is water in the hot rib 1101, the water level reaches the water level of the full water electrode 11042, and the water leakage protection piece 1206 does not detect the water leakage, the water inlet solenoid valve 907 does not open, the hot biliary 1101 does not enter the water.

6. The drinking water machine 1900 is turned on, the water level detector 1104 detects that there is water in the hot rib 1101, and when the water leakage protection piece 1206 detects the water leakage, the controller 10 reports a fault and performs automatic protection state processing, and all work stops; The water should be taken at the hot water tap 902. After restarting, the following situations will occur.

1, the direct drinking water machine 1900 can work normally;

2, the direct drinking water machine 1900 can not work normally, the direct drinking water machine 1900 automatic protection, need to find the cause of the failure;

3. When the water is connected for a while, see if there is any change in the water level.

a. If the water leakage protection sheet 1206 detects a water leakage, the direct drinking water machine 1900 is automatically protected, and the cause of the failure needs to be found.

b. If the water leakage protection sheet 1206 does not detect water leakage, the direct drinking water machine 1900 can resume normal working condition.

7. Press the hot water tap 902 water outlet button, and the water inlet solenoid valve 907 is opened (except for the direct drinking water machine 1900 in the automatic fault protection state).

As shown in Figure 8, the overall working principle of the direct drinking water machine 1900 is as follows:

1. Drinking water machine 1900 is ready for work, and the circuit and waterway are ready.

2. Plug in the power socket and the drinking water machine 1900 is in the standby state. At this time, the power indicator light is red.

3. Press the power button and drink the water machine 1900 out of the working state. At this time, the power indicator light is green. Press the power button again, the drinking water machine 1900 is in standby mode, at this time, the power indicator light is red.

4. Automatic water inlet function: When the drinking water machine 1900 is in the working state, when the water level detector 1104 detects that there is no water in the hot rib 1101 (pulse voltage detection), the water inlet solenoid valve 907 is opened, and the hot stalk 1101 is flooded. When the water level of the full water electrode 11042 is reached, the water inlet solenoid valve 907 is automatically closed.

5. When the direct water 1900 cold water tap 901 or the hot water tap 902 water outlet button is pressed, the water inlet solenoid valve 907 is opened, and the direct drinking water machine 1900 supplies cold or hot drinking water.

6. After the hot bladder 1101 is filled with water, and the water level reaches the water level of the inlet electrode 11041, the drinking water machine 1900 automatically heats the water in the hot bladder 1101 once at 95 ° C, and then heats it once every 24 hours at 95 ° C to circulate.

7, heating - insulation function: When the water temperature of the direct drinking water machine 1900 hot broth 1101 reaches 95 ° C high temperature water, the direct drinking water machine 1900 closes the hot water function, in the heat preservation state, the hot water indicator light is green; when the water temperature is cooled At 80 ° C, the direct drinking water machine 1900 restarts the hot water function, and the hot water indicator light is red. (The water temperature has three models: 95°C, 65°C, and 40°C, and the specific installation depends on actual demand).

8. Sleep function: When the drinking water machine 1900 hot water is kept warm, no one uses high temperature water. After 70 minutes, the drinking water machine 1900 will be in a dormant state. At this time, the hot water indicator will flash continuously, and the hot water function will stop. Other functions are still normal. Only press the heating button again to make hot water again.

9. Water shortage protection: When the drinking water machine 1900 hot water 1101 water enters, if within 8 minutes, the hot water 1101 water level does not reach the inlet water level line, the controller 10 determines that the water shortage protection, the water shortage indicator flashes red. , need to be reset to work.

10. Water leakage protection: When the direct drinking water machine 1900 is in the state of starting, watering, heating, etc., if the water leakage protection piece 1206 is short-circuited by water, the drinking water machine 1900 may have water leakage phenomenon, and the direct drinking water machine 1900 immediately becomes Leakage protection status, the water inlet indicator (red light) flashes, the power indicator (green light), and all functional operations are disabled. Only manually solve the cause of the water leakage failure. For example, after the water droplets on the water leakage protection sheet are wiped dry, the direct drinking water machine 1900 will return to the normal working state.

As shown in FIG. 26 and FIG. 27, another embodiment of the direct drinking water machine 1900 repeats the first embodiment, except that the cold water tap 901 is provided with a first self-resetting travel switch 910, and the first self-reset travel switch 910 is first. The contact is grounded, the second contact of the first self-reset travel switch 910 is electrically connected to the controller 10, and the output end of the controller 10 passes through the water inlet solenoid valve drive circuit 906 and the water inlet connected to the water supply line of the direct drinking water machine 1900. The control end of the solenoid valve 907 is electrically connected; when the cold water is connected, the cold water control handle 9011 drives the control lever of the first self-reset travel switch 910 to turn on the first contact and the second contact of the first self-reset travel switch 910.

A second self-resetting travel switch 911 is disposed on the hot water tap 902. The first contact of the second self-reset travel switch 911 is grounded, and the second contact of the second self-reset travel switch 911 is electrically connected to the controller 10, and the controller 10 The output end is electrically connected to the control end of the water inlet solenoid valve 907 connected to the water supply line of the drinking water machine 1900 through the water inlet solenoid valve driving circuit 906; when the hot water is connected, the hot water control handle 9021 drives the second self-reset stroke The lever of the switch 911 turns on the first contact and the second contact of the second self-reset travel switch 911.

The self-resetting travel switch is similar to the principle of using the normally open reed switch to control the hot and cold water. The water inlet solenoid valve 907 is in a closed state under normal conditions. When the cold water is required to be taken, the cold water control handle 9011 drives the control lever of the first self-reset travel switch 910 to turn on the first contact and the second contact of the first self-reset travel switch 910. After the controller 10 detects the state, The water inlet solenoid valve 907 is driven to open by the water inlet solenoid valve drive circuit 906, and the water in the water supply line of the direct drinking water machine 1900 flows out through the cold water tap 901. The hot water intake process is similar to the cold water intake process. Since the water inlet solenoid valve 907 is in a closed state when no water is taken, the water vapor in the hot cup 1101 can be prevented from heating the water in the water supply line of the drinking water machine 1900, thereby affecting the effect of taking cold water.

As shown in FIG. 30, in another embodiment of the present invention, the raw water purification unit 1902 includes a first-stage PP cotton water purification component 19029, a high-pressure booster pump 1919, a nanofiltration membrane water purification component 1920, or an RO membrane that are sequentially connected. The water purification component 1921, the activated carbon water purification component 19023, the second-stage PP cotton water purification component 19020, etc., may be connected with one or more sanitary water-providing water purification module components according to the raw water quality and the user's requirements. The concentrated water obtained by the nanofiltration membrane water purification unit 1920 or the RO membrane water purification unit 1921 and the raw water from the raw water solenoid valve 19024 flow through the original concentrated water confluence tee 1922 to the first stage PP cotton water purification unit 19029.

In the present invention, where all air is used, the air source is supplied from the air cleaner shown in Fig. 32.
