[0055] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0056] Figure 1 A water purifier provided as an exemplary embodiment of the utility model comprises: a heat preservation water tank 4, a first solenoid valve 3, a second solenoid valve 5, a solar heat collecting tube 1, a solar water storage tank 2 and a controller;

[0057] The solar heat collecting tube 1 is connected to the solar water storage tank 2;

The insulation water tank 4 is provided with a hot water outlet, and the hot water outlet is provided with a second solenoid valve 5. The controller is electrically connected to the first solenoid valve 3 and the second solenoid valve 5 respectively.

[0062] The water inlet is connected to the front water source to store water in the solar water storage tank 2. The solar heat collecting tube 1 can continuously deliver the heat of solar energy to the solar water storage tank 2 to heat the water in the solar water storage tank 2. The solar water storage tank 2 is an insulated water tank that stores the heated purified water in an insulated manner. When the first solenoid valve 3 is opened, the hot water in the solar water storage tank 2 flows into the insulated water tank 4. When the second solenoid valve 5 is opened, the hot water in the insulated water tank 4 flows out through the hot water outlet.

[0063] In this embodiment, solar energy is used to heat the purified water, and the heated purified water is introduced into the insulated water tank, which greatly reduces energy consumption and reduces the waste of electrical energy.

[0064] like Figure 2 As shown, in one embodiment, the water purifier further includes a third solenoid valve 57 and a first temperature sensor 41;

[0065] The solar water storage tank 2 is provided with a drain outlet, and a third solenoid valve 57 is provided at the drain outlet;

[0066] The controller is electrically connected to the third solenoid valve 57 and the first temperature sensor 41 respectively;

[0067] The first temperature sensor 41 is disposed in the solar water storage tank 2, and is used to measure a first water temperature of the solar water storage tank 2, and send the first water temperature to the controller.

[0068] Specifically, the solar water storage tank 2 is provided with a drain outlet, and a third solenoid valve 57 is provided at the drain outlet. When the third solenoid valve 57 is opened, the water in the solar water storage tank 2 is discharged. The first temperature sensor 41 is used to measure the water temperature of the solar water storage tank 2. The controller controls the opening and closing of the third solenoid valve 57 according to the measured first water temperature. The controller can set the outlet water temperature of the hot water outlet. When the first water temperature reaches a higher value than the outlet water temperature setting value of the hot water outlet, the third solenoid valve 57 is opened to discharge part of the hot water in the solar water storage tank 2. The solar water storage tank 2 is supplemented with cold water through the water inlet to maintain the temperature of the hot water in the hot water storage tank at the set value.

[0069] In this embodiment, when the first water temperature in the solar water storage tank 2 exceeds the set value, the controller can control the opening and closing of the third solenoid valve according to the first water temperature, so as to maintain the water temperature in the solar water storage tank 2 by discharging hot water and replenishing cold water.

[0070] In one embodiment, the insulated water tank includes a second temperature sensor 44 and a first water level sensor 43;

[0071] The controller is electrically connected to the second temperature sensor 44 and the first water level sensor 43 respectively;

[0072] The second temperature sensor 44 is disposed in the thermal insulation water tank, and is used to measure the water temperature of the thermal insulation water tank and send the second water temperature to the controller;

[0073] The first water level sensor 43 is disposed in the thermal insulation water tank, and is used to detect the water level of the thermal insulation water tank and send the first water level to the controller;

[0074] Specifically, a first water level sensor 43 is provided in the insulated water tank, and the first water level sensor 43 includes a high water level probe, a middle water level probe and a low water level probe, and can send a first water level to the controller, and the controller can control the opening and closing of the first solenoid valve 3 according to the first water level. When the water level in the insulated water tank is lower than the high water level probe, the first solenoid valve 3 is opened to replenish the insulated water tank; when the water level is higher than the high water level probe, the first solenoid valve 3 is closed. A second temperature sensor 44 is provided in the insulated water tank, and sends a second water temperature to the controller, and the controller can control whether hot water needs to be replenished according to the water temperature information.

[0075] In this embodiment, the first water level sensor 43 and the second temperature sensor 44 can be used to control the water level and temperature in the thermal insulation water tank, thereby controlling whether the thermal insulation water tank needs to be replenished with water.

[0076] In one embodiment, the insulated water tank 4 includes an electric heater 45;

[0077] The electric heater 45 is disposed in the thermal insulation water tank 4 and is electrically connected to the controller.

[0078] Specifically, an electric heater 45 is further provided in the insulated water tank 4 , and the height of the electric heating is lower than the height of the low water level probe. The controller can determine whether to turn on the electric heater 45 based on the second water temperature obtained by the second temperature sensor 44 .

[0079] In this embodiment, if the water temperature in the solar water storage tank 2 does not reach the outlet water temperature set at the hot water outlet on a rainy day or at night, and the water temperature in the insulated water tank 4 does not reach the outlet water temperature set at the hot water outlet, the controller will turn on the electric heater 45 to heat the purified water in the insulated water tank 4, thereby ensuring the water temperature at the hot water outlet.

[0080] like Figure 3 As shown, in one embodiment, the water purifier further includes: an air energy heat pump 12, a circulation pump 13 and a coil heat exchanger 11;

[0081] The air energy heat pump 12 is connected to the coil heat exchanger 11 through a pipeline to form a loop, and a circulation pump 13 is provided in the loop;

[0082] The coil heat exchanger 11 is arranged in the thermal insulation water tank 4;

[0083] The controller is electrically connected to the air energy heat pump 12 and the circulation pump 13 respectively.

[0084] Specifically, the air energy heat pump 12 is connected to the coil heat exchanger 11 to form a loop. The coil heat exchanger 11 is arranged in the insulated water tank 4, and the heat energy in the air can be collected to heat the purified water in the insulated water tank 4. If the water temperature in the solar water tank does not reach the required water temperature on rainy days or at night, and the water temperature in the insulated water tank 4 does not reach the set water temperature, the air energy heat pump will be turned on or turned on at the same time as the electric heater 45 to heat the purified water in the insulated water tank 4 until the second temperature sensor 44 detects that the temperature reaches the set water temperature.

[0085] In this embodiment, if the water temperature in the solar water storage tank 2 does not reach the outlet water temperature set at the hot water outlet on a rainy day or at night, and the water temperature in the insulated water tank 4 does not reach the outlet water temperature set at the hot water outlet, the heat in the air can be collected by air energy to heat the clean water in the insulated water tank, and then assisted by the electric heater 45, thereby further saving electricity.

[0086] In one embodiment, a second water level sensor 42 is provided inside the solar water storage tank 2, the controller is electrically connected to the second water level sensor 42, and the second water level sensor 42 sends the second water level to the controller;

[0087] Specifically, a second water level sensor 42 is provided inside the solar water storage tank 2, and the second water level sensor 42 sends the second water level to the controller. The second water level sensor 42 includes a high water level probe and a low water level probe. When the water level in the solar water storage tank 2 is lower than the high water level probe of the second water level sensor 42, the solar water storage tank 2 is replenished with water.

[0088] In this embodiment, the second water level sensor 42 can replenish water to the solar water storage tank 2 in time when the water level is lower than the high water level probe.

[0089] In one embodiment, a drain port is provided at the bottom of the thermal insulation water tank 4, and a fourth solenoid valve 56 is provided at the drain port;

[0090] The controller is connected to the fourth solenoid valve 56 .

[0091] Specifically, the controller can control the fourth solenoid valve 56 to discharge the clean water in the thermal insulation water tank 4 through the bottom drain port;

[0092] In this embodiment, the drain outlet can be used to discharge the clean water, which is convenient for users to clean the insulated water tank 4 or to clean the pipeline.

[0093] In one embodiment, the water purifier further includes a pressure barrel 34, a first filter device 30, a fifth solenoid valve 54 and a sixth solenoid valve 51;

[0094] The first water outlet of the pressure barrel 34 is connected to the water inlet of the first filtering device 30 through a second pipeline;

[0095] The water inlet of the first filter device 30 is connected to the heat preservation water tank 4 through a third pipeline, and a fifth solenoid valve 54 is arranged on the third pipeline;

[0096] The second water outlet of the pressure tank 34 is connected to the water inlet of the solar water storage tank 2 through a fourth pipeline, and the water inlet of the solar water storage tank 2 is provided with a sixth solenoid valve 51;

[0097] The controller is electrically connected to the fifth solenoid valve 54 and the sixth solenoid valve 51 respectively.

[0098] Specifically, the first filter device 30 can be a granular activated carbon filter element or a carbon rod filter element; the pressure barrel 34 is used to store clean water, and there is an air bag inside the pressure barrel 34. The filtered clean water will be stored in the pressure barrel 34, and the water will squeeze the air bag, so that the clean water is stored in the barrel. The pressure barrel 34 has two water outlets, and the first water outlet of the pressure barrel 34 is connected to the water inlet of the first filter device 30 through the second pipeline; the second pipeline is provided with a fifth solenoid valve 54; the second water outlet of the pressure barrel 34 is connected to the water inlet of the solar water storage tank 2 through the fourth pipeline; the fourth pipeline is provided with a sixth solenoid valve 51; when the fifth solenoid valve 54 or the sixth solenoid valve 51 is opened, the water in the pressure barrel 34 will be squeezed out by the air bag, so that the clean water is released. In this way, the thermal insulation water tank 4 and the solar water storage tank 2 can be replenished with water.

[0099] Generally, the water replenishment method is that when the second water level in the solar water storage tank 2 is higher than the low water level, and the thermal insulation tank 4 needs to be replenished, the first solenoid valve 3 is opened to replenish the thermal insulation tank 4, and when the second water level in the solar water storage tank 2 is lower than the low water level, the sixth solenoid valve 51 is opened to replenish the water tank. However, when it is cloudy and rainy, that is, when the temperature of the temperature sensor is less than the set value, for example, 45°C, the controller will open and directly replenish the thermal insulation tank 4, that is, directly open the fifth solenoid valve 54.

[0100] In this embodiment, clean water can be stored by setting up a pressure barrel 34. The pressure barrel 34 replenishes the thermal insulation water tank 4 and the solar water storage tank 2 according to different situations, making the replenishment of the thermal insulation water tank 4 more flexible.

[0101] In one embodiment, the water purifier further includes: a second filter device 31, a third filter device 32 and a booster pump 33;

[0102] The water inlet of the second filtering device 31 is used to access an external water source;

The booster pump 33 is a diaphragm booster pump. The third filter device 32 is a reverse osmosis membrane filter element, which can be an RO membrane or a NF nanofiltration membrane. The external water source enters the water purifier through the water inlet of the second filter device 31, passes through the third filter device 32 through the booster pump, and then enters the pressure barrel 34.

[0107] In this embodiment, the second filter device 31 and the third filter device 32 can be used to filter the external water source and store the filtered clean water to facilitate the subsequent water replenishment of the solar water storage tank 2 and the thermal insulation water tank 4.

[0117] In this embodiment, by setting the high pressure switch 48, the controller can close the seventh solenoid valve 52 and the booster to stop water production when the high pressure value is detected. If the high pressure value is not detected, water production continues and the purified water continues to be stored in the pressure tank 34.

[0130] In one embodiment, the water purifier further comprises:

[0131] The fourth one-way valve is arranged on the third pipeline connecting the pressure barrel 34 and the thermal insulation water tank 4 .

[0132] In this embodiment, a one-way valve is used to prevent the heat preservation water tank 4 from flowing back into the pressure tank 34.

[0133] Specifically, Figure 4 As shown, the working process of the entire water purifier system is as follows;

[0134] Power-on flushing: After the whole machine is turned on, the seventh solenoid valve 52, the booster pump 33, and the eighth solenoid valve 53 are all turned on. The system defaults to a duration of 15 minutes. The time here can be set according to the size of the third filter device 32.

[0135] Water production and flushing: After executing the first action mentioned above, the system enters water production and flushing, the seventh solenoid valve 52 and the booster pump 33 are turned on, and the system starts to produce water until the high-pressure switch 48 detects the high-pressure pressure signal and then shuts down. At this time, the ninth solenoid valve 55 is turned on, and the opening time is related to the size of the pressure barrel 34. The system defaults to 15 minutes, so that all the clean water in the pressure barrel 34 can be drained. The system defaults to executing this process 3 times, but when the water quality detection sensor 47 detects that the COD detection value is less than the system preset value, the program can be stopped in advance, otherwise it can continue to produce water and flush. Generally, the system defaults to a COD value of 1mg / l.

[0136] Cleaning the whole machine: After performing the above actions, the seventh solenoid valve 52, the booster pump 33, the fifth solenoid valve 54 and the sixth solenoid valve 51 are all opened. When the first water level sensor 43 and the second water level sensor 42 in the thermal insulation water tank 4 and the solar water storage tank 2 detect high water levels, the corresponding water replenishment solenoid valves are closed respectively, that is, the thermal insulation water tank 4 corresponds to the fifth solenoid valve 54, and the solar water storage tank 2 corresponds to the sixth solenoid valve 51. After the two water level sensors detect the high water level, the seventh solenoid valve 52, the booster pump 33, the fifth solenoid valve 54 and the sixth solenoid valve 51 are all closed. At this time, the third solenoid valve 57 and the fourth solenoid valve 56 are opened, and the start time defaults to 15 minutes. The time here needs to be set according to the size of the two water tanks.

[0137] The whole machine water making and heating process: After executing the whole machine cleaning action, enter this logic, the seventh solenoid valve 52, the booster pump 33, the fifth solenoid valve 54 and the sixth solenoid valve 51 are all opened, and the system starts to make water. When the low water level probe of the first water level sensor 43 in the thermal insulation water tank 4 detects low water, the electric heater 45 and the air energy heat pump will be turned on, and the water replenishment solenoid valve 1 is closed. At this time, water is still being made, and the purified water continues to replenish water in the solar water storage tank 2 and the pressure barrel 34 until the second water level sensor 42 in the solar water storage tank 2 detects a high water level and the sixth solenoid valve 51 is closed. At this time, if a high pressure value is detected in the water purifier system, the seventh solenoid valve 52 and the booster pump 33 in the filtration system are all closed, but if no high pressure value is detected at this time, water production continues. The second temperature sensor 44 in the insulated water tank 4 detects the temperature value in real time. If the temperature reaches the system preset temperature, the default is 95°C, the heating will be stopped, that is, the electric heater 45 and the air energy heat pump 12 will stop heating. At this time, the fifth solenoid valve 54 is opened, and water is continued to be added to the insulated water tank 4 until the water level probe in the first water level sensor 43 detects that the liquid level stops, that is, the fifth solenoid valve 54 is closed. If the high-pressure switch 48 detects a low pressure value at this time, the filtration system starts to make water until the high-pressure switch 48 detects a high pressure value and stops making water. At this time, the electric heater 45 and the air energy heat pump 12 start heating until the second temperature sensor 44 detects that the temperature value reaches the system preset value and stops. At this time, the fifth solenoid valve 54 continues to be opened until the high water level probe of the first water level sensor 43 in the thermal insulation water tank 4 detects that the water level stops. At this time, if the high pressure switch 48 detects a low pressure value, the filtration system enters the water production mode until the high pressure switch 48 detects a high pressure value and stops water production. At the same time, the electric heater 45 and the air energy heat pump 12 in the thermal insulation water tank 4 are started until the second temperature sensor 44 detects that the temperature reaches the system preset value and stops heating. At this time, the hot water in the thermal insulation water tank 4 has reached the system preset temperature, and the hot water in the thermal insulation water tank 4 is also in a full water state. At the same time, the clean water in our solar water storage tank 2 is also full of water. During the day, the solar heat collecting tube 1 will continuously transport the heat energy of the solar energy to the solar water storage tank 2, that is, except for the first time of whole machine water replenishment, which is directly replenished from the filtration system, the subsequent water replenishment action will be replenished from the solar water storage tank 2, that is, the subsequent water replenishment method is when the second water level sensor 42 in the solar water storage tank 2 detects that the water level is greater than the low water level, and the insulation water tank 4 needs to be replenished, then the first electromagnetic valve 3 is opened to replenish the insulation water tank 4, and when the water level in the solar water storage tank 2 is lower than the low water level, the sixth electromagnetic valve 51 is opened to replenish the water tank. However, when it is cloudy and rainy, that is, when the temperature of the first temperature sensor 41 is less than 45°C, the system will directly replenish the insulation water tank 4, that is, directly open the fifth electromagnetic valve 54.

[0138] Water extraction: When hot water is extracted, no matter it is a low water level, a medium water level or a high water level, as long as the second temperature sensor 44 detects that the temperature is greater than 85°C and there is a water extraction action, the fourth solenoid valve 56 opens and hot water can be released.

[0139] When taking water at room temperature, the ninth solenoid valve 55 and the sterilizer 46 are opened, and the system detects the pressure value of the high-pressure switch 48 in real time. When the high-pressure switch 48 detects a low pressure value, the system enters the water making mode.

[0140] Insulation mode: When the insulation water tank 4 is replenished with water and reaches a high water level, and the system detects that the time is between midnight and 5 a.m., if the second temperature sensor 44 detects that the water temperature of the insulation water tank 4 is lower than the system preset temperature, which is defined as 85°C, the electric heater 45 and the air energy heat pump 12 will stop working until the second temperature sensor 44 detects that the temperature is the system preset temperature, and the cycle continues during this period.

[0141] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
