[0025] As Figure 1 A fully enclosed reverse osmosis heat pump low-temperature distillation water production device shown in the figure includes a water inlet solenoid valve 1, an ejector 2, an RO reverse osmosis module 3 and a heat preservation box 4 that are connected in sequence. The RO reverse osmosis module 3 is connected to the bottom of the heat preservation box 4, and a distillation chamber 5 is formed inside the heat preservation box 4. A heat pump low-temperature distillation system is provided on the upper two sections of the heat preservation box 4. The heat pump low-temperature distillation system includes a compressor 6, a condenser 7, an expansion valve 8 and a plurality of evaporators 9 that form a loop in sequence. Among them, the compressor 6 and the expansion valve 8 are arranged outside the heat preservation box 4. The condenser 7 is installed at the bottom of the distillation chamber 5 and is suitable for heating and evaporating water bodies. A plurality of evaporators 9 are installed in series at the upper part of the distillation chamber 5 and are suitable for condensing water vapor. A water receiving box 10 for receiving condensed water is installed at the bottom of the evaporator 9. The lower ends of a plurality of water receiving boxes 10 are connected to a distilled water outlet pipe 11, and the outlet of the distilled water outlet pipe 11 extends outside the heat preservation box 4.

[0026] In the above technical solution, a heat pump system is integrated in the distillation chamber of the device. The evaporator and condenser of the heat pump system are respectively arranged at the upper and lower parts of the distillation chamber. The condenser can evaporate water bodies, and the evaporator can condense water vapor. After the condensed water enters the water receiving box, it can flow out of the outside of the heat preservation box through the distilled water outlet pipe at the bottom. The heat pump can work at a higher energy efficiency ratio, which is more energy-saving and more environmentally friendly than traditional fuel combustion heating or direct electric heating distillation. Moreover, based on the principle that the evaporator in the heat pump system absorbs heat energy, pure water can be directly condensed and extracted without an external condensing device. The device has a high degree of integration and can realize modular production. In addition, before distillation, the RO reverse osmosis module (PP cotton filter element + coconut shell activated carbon filter element + RO filter element) can quickly purify water in the early stage, making the water entering the distillation chamber purer, improving the distillation efficiency and enhancing the water quality. It should be noted here that the number of evaporators and condensers can be set according to the usage requirements of the device.

[0027] Further, a concentrated water solenoid valve 12 is communicatively connected between the bottom of the heat preservation box body 4 and the injector 2. In this technical solution, the concentrated water solenoid valve can mix the water remaining after evaporation and concentration in the evaporation chamber (the water below the low water level) into the tap water and add it to the RO reverse osmosis module for recovery, avoiding waste of water resources. Moreover, the concentrated water still has a certain amount of heat, which can be mixed with the tap water, purified, and then sent back into the evaporation chamber again to recover the heat.

[0028] Further, a low water level sensor 13 is provided on the bottom side wall of the distillation chamber 5, and the low water level sensor 13 is located above the condenser 7. In this technical solution, when the water level in the distillation chamber reaches the low water level sensor, the low water level sensor transmits the sensed water level signal to the controller to enable the controller to start the compressor and evaporate the water body in the condenser.

[0029] Further, a high water level sensor 14 is provided on the side wall of the distillation chamber 5 between the distilled water outlet pipe 11 and the low water level sensor 13. In this technical solution, after the water level in the distillation chamber reaches the high water level sensor, to prevent the water level from exceeding the limit, the high water level sensor transmits the sensed water level signal to the controller to stop the RO reverse osmosis module from working, close the concentrated water solenoid valve, and close the water inlet solenoid valve, allowing the heat pump system to continue working to produce distilled water.

[0030] Further, a first check valve 15 is communicatively connected between the concentrated water solenoid valve 12 and the injector 2, adapted to allow the water flow to flow from the concentrated water solenoid valve 12 to the injector 2; a second check valve 16 is communicatively connected between the RO reverse osmosis module 3 and the heat preservation box body 4, adapted to allow the water flow to flow from the RO reverse osmosis module 3 to the heat preservation box body 4. In this technical solution, both the first check valve and the second check valve prevent the water body from flowing back, improving the water flow stability of the equipment.

[0031] Further, an installation hole is opened on the inner wall of the distillation chamber 5 below the low water level sensor 13. A water guide pipe 17 extending outside the heat preservation box body 4 is provided on the installation hole. The other end of the water guide pipe 17 extends into the upper end of the heat preservation box body 4 and is provided with a water distributor 18. The water distributor 18 is located above the distilled water outlet pipe 11. A circulation pump 19 is provided on the water guide pipe 17 outside the heat preservation box body 4. In this technical solution, the circulation pump can pump the water body in the distillation chamber above the distillation chamber and evenly drop it through the water distributor, increasing the contact area between the liquid water and the air, accelerating the evaporation of the water body, and improving the distillation efficiency.

[0032] Further, a heat preservation cotton 20 is provided on the pipe between the compressor 6 and the evaporator 9 outside the heat preservation box body 4; the water inlet end of the water inlet solenoid valve 1 is connected to a tap water pipe 21, and a waste water drain pipe 22 is provided on the RO reverse osmosis module 3. In this technical solution, the heat preservation cotton can insulate the exposed part of this pipe to prevent heat loss.

[0033] In this specific embodiment, for the problem that the heat source for making distilled water in the prior art is fuel energy, with low energy utilization rate, a large amount of carbon emissions, and the distilled water condensation module continuously passes in normal temperature water for condensation, and the normal temperature water is discharged after absorbing the condensation heat, resulting in energy waste and water resource waste, the above solution integrates a heat pump system in the distilled water production equipment. The heat pump can work at a higher energy efficiency ratio, is more energy-saving and environmentally friendly than traditional fuel combustion heating or direct electric heating for distillation. Moreover, based on the principle that the evaporator in the heat pump system absorbs heat energy, pure water can be directly condensed and extracted without an external condensation device, and the equipment has a high degree of integration and can achieve modular production. In addition, during the use of the equipment, the heat energy released by the condenser changes the water phase, and the evaporator condenses and recovers the heat energy, without additional energy waste, ensuring the maximum energy utilization during the operation of the system. Additionally, before distillation, the RO reverse osmosis module (PP cotton filter element + coconut shell activated carbon filter element + RO filter element) can quickly purify water in the early stage, making the water entering the distillation chamber purer, improving the distillation efficiency and water quality. A concentrated water solenoid valve is set on the equipment to recover the concentrated water after evaporation, avoiding energy waste and water resource waste. A water distributor is set at the upper part of the distillation chamber to accelerate the evaporation of the water body and improve the distillation efficiency.

[0034] The specific working principle of this case is as follows:

[0035] The water inlet is connected to the tap water pipe; the equipment is powered on and the start switch is pressed; the water inlet solenoid valve is opened; water passes through the ejector and sucks the concentrated water in the distillation chamber through the concentrated water solenoid valve, and is sent to the RO reverse osmosis module; after being processed by the RO reverse osmosis module, it is sent to the distillation chamber, and the RO concentrated waste water is discharged; when the water level reaches the low water level, the compressor works, the condenser heats the water body, and the evaporator condenses; the condensed water of the evaporator is collected through the water receiving box and discharged from the outlet of the distilled water outlet pipe for collection and use; the circulation pump is turned on to accelerate evaporation through the water distributor; when the liquid level in the evaporator reaches the high water level sensor, the RO reverse osmosis module stops working, the concentrated water solenoid valve is closed, and the water inlet solenoid valve is closed; when the water level reaches the low water level sensor, the concentrated water solenoid valve is opened, the water inlet solenoid valve is opened, and the RO reverse osmosis module starts to work to replenish water into the distillation chamber; when the stop button is pressed, the compressor stops working, the water inlet solenoid valve is closed, the concentrated water solenoid valve is closed, the RO reverse osmosis module is closed, and the whole machine stops working.
