[0051] Example 1

[0052] This disclosure provides a water circuit system for an under-sink soft drink heating machine, referring to... Figure 1 The under-sink water purifier, soft water dispenser, and hot water machine's water system includes: a pre-filter 1, a central water purifier 2, a soft water machine 3, a reverse osmosis water purifier 4, and a heating device 5. In the diagram, the thin black solid lines represent the water circuit connections, and the green lines represent the electrical connections.

[0053] The inlet of the pre-filter 1 is connected to the raw water inlet, and the outlet of the pre-filter 1 is connected to the inlet of the central water purifier 2, the inlet of the water softener 3, and the inlet of the first branch of the heating device 5.

[0054] The outlet of the central water purifier 2 is connected to the inlet of the reverse osmosis water purifier 4, the outlet of the reverse osmosis water purifier 4 is connected to the inlet of the second branch of the heating device 5, and the wastewater outlet of the reverse osmosis water purifier 4 is connected to the wastewater outlet.

[0055] The outlet of the first branch of the heating device 5 is connected to the clean heat outlet, and the outlet of the second branch of the heating device 5 is connected to the hot water outlet.

[0056] The outlet of water softener 3 is connected to the water softener outlet.

[0057] The pre-filter 1 can be a PP cotton filter element, which can be a polypropylene melt-blown filter element or a dust collection cloth, with a filtration accuracy of 75-100 microns. Alternatively, it can be a stainless steel filter mesh, with a filtration accuracy of 75-100 microns.

[0058] The purified water filtered by the pre-filter 1 can be divided into 4 channels. The first channel is delivered to the cleaning module. The cleaning port is connected to the room temperature water outlet of the user's kitchen faucet. Since the faucet has a valve core controller switch, it is not shown here.

[0059] The second water supply line is sent to the heating device 5. Specifically, it first supplies water to the hot water tank 51, which has an inlet and outlet. This tank is a pressurized water tank, and a first temperature probe T1 is installed on the top. A thermostat W is installed on the side near the electric heater 52. Inside the hot water tank 51, the electric heater 52 and a coil heat exchanger 53 are installed. The inlet of the coil heat exchanger 53 is connected to the outlet of the post-filter, and the outlet of the coil heat exchanger 53 is connected to the hot water inlet of the kitchen drinking water faucet. The hot water outlet of the hot water tank 51 is connected to the hot water inlet (clean hot water outlet) of the kitchen faucet. A safety valve M4 is also installed at the inlet of the hot water tank 51. This safety valve not only relieves pressure but also functions as a one-way valve.

[0060] The third water outlet is supplied to water softener 3, becoming the inlet water for water softener 3. Water softener 3 has an overflow outlet, a drain outlet, a softened water outlet, and a brine inlet.

[0061] The fourth water output is supplied to the direct drinking water unit, specifically connected to the inlet of the second electric valve M2, which is an electric ball valve. The outlet of the second electric valve M2 connects to the carbon rod filter element of the central water purifier 2. The outlet of the carbon rod filter element can connect to the inlet of the water pump P. The outlet of the water pump P can connect to the nanofiltration filter element in the reverse osmosis water purifier 4. The outlet of the nanofiltration filter element connects to the post-filter element in the reverse osmosis water purifier 4. The nanofiltration filter element can be a nanofiltration membrane or a reverse osmosis (RO) membrane, and the post-filter element can be a carbon rod filter element or a granular activated carbon filter element. The outlet of the post-filter element is divided into two paths. One path connects directly to the purified water inlet, which is connected to the inlet of the purified water faucet. A water usage signal is given whenever the faucet is turned on. The other path connects to the inlet of the coil heat exchanger 53. The outlet of the coil heat exchanger 53 connects to the hot water inlet (hot water outlet) of the hot water faucet via the rapid heating module 54. The system operates whenever a hot water usage signal (command) is given.

[0062] In this embodiment, the under-sink pre-filter, central water purifier, water softener, reverse osmosis water purifier, and heating device are all integrated into one unit with a professional and reasonable size configuration.

[0066] The inlet of the coil heat exchanger 53 is used as the inlet of the second branch of the heating device 5. The outlet of the coil heat exchanger 53 is connected to the inlet of the rapid heating module 54, and the outlet of the rapid heating module 54 is used as the outlet of the second branch of the heating device 5.

[0067] In one embodiment, the water circuit system of the under-sink soft drink heating machine further includes: a controller 6 and a first electric valve M1.

[0068] The first electric valve M1 is located at the inlet of the pre-filter 1.

[0069] The first electric valve M1 is electrically connected to the controller 6.

[0070] The controller 6 sends a command to the first electric valve M1 to control the connection between the inlet of the pre-filter 1 and the raw water inlet.

[0071] Among them, the first electric valve M1 is the main water inlet pipe of the whole machine. The valve is driven by a motor to open and close. Normally, the valve is in the open state, and it is closed and opened once a week during a preset time period of the system. The purpose of this action is to prevent it from not being able to close due to prolonged inactivity.

[0072] In one embodiment, the water circuit system of the under-sink soft drink heating machine further includes: a wastewater solenoid valve M3.

[0073] Wastewater solenoid valve M3 is installed at the wastewater outlet of reverse osmosis water purifier 4.

[0074] Wastewater solenoid valve M3 is electrically connected to controller 6.

[0075] The controller 6 also sends instructions to the wastewater solenoid valve M3 to control the connection status between the wastewater outlet and the wastewater port of the reverse osmosis water purifier 4.

[0076] In one embodiment, the water circuit system of the under-sink soft drink heating machine further includes: a second electric valve M2 and a water pump P.

[0077] The second electric valve M2 is installed at the inlet of the central water purifier 2.

[0078] The second electric valve M2 and the water pump are both electrically connected to the controller 6.

[0079] The controller 6 also sends instructions to the second electric valve M2 to control the connection between the outlet of the pre-filter 1 and the inlet of the central water purifier 2.

[0080] The controller 6 also sends instructions to the water pump P to control the water flow between the pre-filter 1 and the central water purifier 2.

[0081] In one embodiment, the water circuit system of the under-sink soft drink heating machine further includes: a safety valve M4 and a check valve M5.

[0082] Safety valve M4 is located at the inlet of the first branch of heating device 5.

[0083] One-way valve M5 is installed at the inlet of the second branch of heating device 5.

[0084] Safety valve M4 and check valve M5 are both electrically connected to controller 6.

[0085] The controller 6 also sends a command to the safety valve M4 to control the connection between the outlet of the pre-filter 1 and the inlet of the first branch of the heating device 5.

[0086] The controller 6 also sends instructions to the one-way valve M5 to control the connection between the outlet of the reverse osmosis water purifier 4 and the inlet of the second branch of the heating device 5.

[0087] In one embodiment, the water circuit system of the under-sink soft drink heating machine further includes: a leak protector 7.

[0088] The water leakage protector 7 is electrically connected to the controller 6.

[0089] The leak protector 7 is used to detect the leakage status of the raw water inlet and send the leakage status to the controller 6.

[0090] When the water leakage protector 7 detects water leakage, it will transmit a signal to the controller 6, and the controller 6 will give a signal to close the first electric valve M1.

[0091] In one embodiment, the water circuit system of the under-sink soft drink heating machine further includes: a controller 6, a thermostat W, a first temperature probe T1, and a second temperature probe T2.

[0092] The controller 6 is electrically connected to the temperature controller W, the first temperature probe T1, and the second temperature probe T2, respectively.

[0093] The thermostat W is located on the side of the hot water tank 51 and near the electric heater 52.

[0094] The controller 6 sends a command to the temperature controller W to control the conduction of the electric heater 52.

[0095] The first temperature probe T1 is located on the top of the hot water tank 51 and sends the detection data to the controller 6.

[0096] The second temperature probe T2 is located at the rapid heating module 54 and sends the detection data to the controller 6.

[0097] In one embodiment, the outlet of the pre-filter 1 is also connected to the rinsing port.

[0098] In one embodiment, the outlet of the reverse osmosis water purifier 4 is also connected to the purified water outlet.

[0099] In one embodiment, the water softener 3 also provides an overflow outlet, a brine inlet, and a drain outlet.

[0100] In this embodiment, the first electric valve M1 is open by default in the system. The system is preset to perform a switching action at 3:00 AM on the 7th day. This is mainly to prevent the valve from being in a state of inactivity for a long time. Firstly, 3:00 AM is the time when the soft water has not been regenerated. If the soft water is being regenerated at this time, the action can be performed after the regeneration is completed.

[0101] Since the purified water and purified hot water are not controlled by valves, they are mainly controlled by the user's tap, so water will flow out as long as the tap is turned on.

[0102] Hot water tank heating logic: After the system is debugged, the hot water tank is full by default. At this time, the electric heater starts to work until the temperature reaches the system preset temperature, which is 45 degrees Celsius by default. The user can adjust the temperature himself. Heating stops after the preset temperature is reached, and heating starts again when the temperature is lower than the system preset temperature.

[0103] Water purification logic: As long as the water purifier faucet gives an electrical signal, the electric valve 2 will open, the pump will start, and the filtration system will start producing water. At this time, purified water will flow out of the water purifier outlet. When the system has accumulated more than 3 hours of water production, the electric valve 2, the wastewater solenoid valve, and the pump will all open for 60 seconds. This is mainly to flush the filter element to prevent it from clogging.

[0104] Hot water outlet logic: As long as the hot water faucet gives a signal, electric valve 2 and pump will both open. If the temperature given by the faucet is too high and the temperature in the hot water tank does not meet the requirements, the rapid heating module will also be activated until the required temperature is reached. When the hot water outlet stops, the rapid heating module will stop heating, and electric valve 2, pump and wastewater solenoid valve will also stop. The reason for stopping the rapid heating module for 1-2 seconds first is to prevent dry burning, which would reduce its service life.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this disclosure, but all such changes and modifications fall within the scope of protection of this disclosure.
