Description

Technical Field

[0001] The utility model relates to the technical field of zero - cold - water heaters, and specifically relates to a DC constant - pressure boosting zero - cold - water integrated machine. Background Technique

[0002] A water return device often needs to be installed on a water heater to achieve zero - cold - water treatment. During specific operation, the water return device uses an internal DC circulation pump to realize the back - pumping and heating treatment of the cold water in the hot water pipe. This is beneficial for the user to obtain hot water immediately when turning on the faucet later. This technology solves the problem that traditional water heaters need to drain a part of cold water before use, improving the comfort of use.

[0003] Since such water return devices often can only achieve a single cycle water return function during actual operation, it is not easy to integrate a temperature - measurable and pressure - adjustable water return pipe structure to achieve two - stage water return heating treatment. This results in an incomplete water return and hot water effect of the device on the water heater. Moreover, it often can only achieve control functions through the operation buttons on the water return device panel and is not easy to set a suitable wireless control structure according to operation requirements. This leads to inconvenient operation and low practicality of the device, and it can no longer meet people's needs. Therefore, we propose a new type of DC constant - pressure boosting zero - cold - water integrated machine to solve the above - mentioned defects. Content of the Utility Model

[0004] The purpose of the utility model is to provide a DC constant - pressure boosting zero - cold - water integrated machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A DC constant - pressure boosting zero - cold - water integrated machine includes a water return device housing, and also includes

[0006] A zero - cold - water adjustment pipe group, the zero - cold - water adjustment pipe group is connected to the water return device housing. A back panel is clamped on one side of the water return device housing. A DC circulation pump is installed inside the water return device housing. A circuit board is installed on the back panel. Threaded assembly pipe fittings communicating with the zero - cold - water adjustment pipe group are respectively arranged at the input end and the output end of the DC circulation pump;

[0007] A WI - FI antenna matching the circuit board is clamped on the top of the water return device housing. A hand - held remote controller, a wall - mounted remote controller and a doorbell wire control switch are connected to the water return device housing;

[0008] The zero - cold - water adjustment pipe group includes a water pressure control valve, a water flow induction switch, a temperature induction probe, a water return pipe, a reserved hot water pipe for the water heater, a cold water inlet pipe and a connecting pipe for the water heater. The water return pipe and the connecting pipe for the water heater are respectively connected to the bottom and the top of the water return device housing;

[0009] The cold water inlet pipe is connected to one end of the return water pipe away from the return water device housing, and the cold water inlet pipe is arranged on one side of the connecting pipe for the water heater;

[0010] The water flow induction switch, the water pressure control valve and the temperature induction probe are sequentially installed on the return water pipe.

[0011] Further, a snap connection is formed between the back plate and the return water device housing, and screws are evenly arranged between the back plate and the return water device housing, facilitating the disassembly, assembly and maintenance of the back plate and the return water device housing.

[0012] Further, the DC circulation pump and the return water device housing, as well as the circuit board and the back plate, are all detachably installed structures through screws.

[0013] Further, damping, vibration reduction and sound absorption felts are adhesively bonded to the inner side walls of the return water device housing and the back plate, improving the buffering, sound absorption and noise reduction effects of the inner walls of the return water device housing and the back plate, and being beneficial to reducing the noise pollution caused by the operation of the DC circulation pump and the vibration impact on the return water device housing. [[ID=@13]]

[0014] Further, honeycomb-shaped sound absorption holes are evenly arranged on the damping, vibration reduction and sound absorption felt. When sound energy passes through the honeycomb-shaped sound absorption holes, the air vibration inside the hole structure is excited, so that the kinetic energy of the air is continuously converted into heat energy to achieve the attenuation of sound energy, thereby improving the sound absorption performance of the damping, vibration reduction and sound absorption felt.

[0015] Further, nano-titanium dioxide self-cleaning layers are coated on the outer side walls of the return water device housing and the back plate, improving the anti-pollution and corrosion resistance of the outer wall of the device.

[0016] Further, aluminum alloy bases are arranged inside the side walls of the return water device housing and the back plate, ensuring the structural strength of the device by using a metal framework.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] The DC constant-voltage boosting zero-cold-water integrated machine is equipped with a water flow induction switch, etc., which optimizes its own structure. On the one hand, when the user opens the faucet, the DC circulation pump inside the return water machine case will start, pumping the cold water in the reserved hot water pipe of the water heater back to the corresponding water heater for reheating. At the same time, the return water pipe will guide the cold water in the reserved hot water pipe of the water heater back to the corresponding water heater for reheating. This helps to ensure that the entire reserved hot water pipe inside the water heater is hot water and guarantees that the hot water finally discharged to the water-using structures such as the faucet is hot water. When the water heater detects that the water temperature in the reserved hot water pipe of the water heater has reached the set value, the DC circulation pump will stop working and wait for the next use, realizing the function of hot water coming out immediately when the faucet is opened. This technology solves the problem that traditional water heaters need to drain a part of cold water before use, improving the comfort and energy-saving performance of use. Moreover, the water flow induction switch, water pressure control valve, and temperature induction probe installed in sequence on the return water pipe can realize the function of intelligently regulating the pressure of the return water and intelligently monitoring the temperature of the return water when the return water is sensed. Then, through the control circuit electrically connected to the corresponding water heater on the circuit board, it is beneficial to intelligently regulate the pressure and temperature of the finally discharged hot water and achieve constant temperature and constant pressure protection. On the other hand, by clamping a WIFI antenna matching the circuit board at the top of the return water machine case, it is convenient to wirelessly connect the hand-held remote controller, wall-mounted remote controller, and doorbell wire control switch to the return water machine case, so that the device realizes the advantages of optional control methods, more convenient and practical operation, and is convenient for popularization.

[0027] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a DC constant voltage boosting zero cold water integrated machine, including a return water machine shell 1, and further including

[0028] A zero cold water regulating pipe group 3, the zero cold water regulating pipe group 3 is connected to the return water machine shell 1, a back plate 8 is clamped on one side of the return water machine shell 1, a DC circulation pump 10 is installed inside the return water machine shell 1, and a circuit board 9 is installed on the back plate 8.

[0029] A WIFI antenna 2 matching the circuit board 9 is clamped at the top of the return water machine shell 1, and a hand-held remote controller 4, a wall-mounted remote controller 5 and a doorbell wire control switch 6 are connected to the return water machine shell 1;

[0030] The zero cold water regulating pipe group 3 includes a water pressure control valve 11, a water flow induction switch 12, a temperature induction probe 13, a return water pipe 14, a hot water pipe reserved for the water heater 15, a cold water inlet pipe 16 and a connecting pipe 17 for the water heater. The return water pipe 14 and the connecting pipe 17 for the water heater are respectively connected to the bottom and the top of the return water machine shell 1;

[0031] The cold water inlet pipe 16 is connected to one end of the return water pipe 14 away from the return water machine shell 1, and the cold water inlet pipe 16 is arranged on one side of the connecting pipe 17 for the water heater;

[0032] When in use, when the user turns on the faucet, the DC circulation pump 10 inside the return water device housing 1 will start, pumping the cold water in the reserved hot water pipe 15 of the water heater back to the corresponding water heater for reheating. At the same time, the return water pipe 14 will guide the cold water in the reserved hot water pipe 15 of the water heater back to the corresponding water heater for reheating. This helps ensure that the entire reserved hot water pipe 15 of the water heater is filled with hot water and guarantees that the water discharged to water-using structures such as faucets is hot water. When the water heater detects that the water temperature in the reserved hot water pipe 15 of the water heater has reached the set value, the DC circulation pump 10 will stop working and wait for the next use, realizing the function of getting hot water immediately when the faucet is turned on. This technology solves the problem that traditional water heaters need to drain a part of cold water before use, improving the comfort of use and energy-saving performance;

[0033] The water flow induction switch 12, the water pressure control valve 11, and the temperature induction probe 13 are sequentially installed on the return water pipe 14;

[0034] A snap connection is formed between the back panel 8 and the return water device housing 1, and screws are evenly arranged between the back panel 8 and the return water device housing 1, making it convenient to disassemble and maintain the back panel 8 and the return water device housing 1;

[0037] Honeycomb-shaped sound-absorbing holes 21 are evenly arranged on the damping and vibration-absorbing sound-absorbing felt 18. When sound energy passes through the honeycomb-shaped sound-absorbing holes 21, it excites the air vibration inside the hole structure, continuously converting the kinetic energy of the air into heat energy to attenuate the sound energy, thereby enhancing the sound-absorbing performance of the damping and vibration-absorbing sound-absorbing felt 18;

During actual operation, when the user turns on the faucet, the DC circulation pump 10 inside the water returner housing 1 will start, pumping the cold water in the reserved hot water pipe 15 of the water heater back into the corresponding water heater for reheating. At the same time, the return water pipe 14 will guide the cold water in the reserved hot water pipe 15 of the water heater back into the corresponding water heater for reheating. This helps to ensure that the entire reserved hot water pipe 15 of the water heater is filled with hot water and that the water finally discharged to water-using structures such as faucets is hot water. When the water heater detects that the water temperature in the reserved hot water pipe 15 has reached the set value, the DC circulation pump 10 will stop working and wait for the next use, realizing the function of hot water flowing out immediately when the faucet is turned on. This technology solves the problem that traditional water heaters need to discharge a part of cold water before use, improving the comfort and energy-saving performance of use. Moreover, the water flow induction switch 12, the water pressure control valve 11, and the temperature induction probe 13 successively installed on the return water pipe 14 can realize the intelligent regulation of the pressure of the return water and the intelligent monitoring of the temperature of the return water when the return water is sensed. Then, through the control circuit electrically connected to the corresponding water heater on the circuit board 9, it is beneficial to intelligently regulate the pressure and temperature of the finally discharged hot water and achieve constant temperature and constant pressure protection. In addition, by clamping a WI FI antenna 2 matching the circuit board 9 at the top of the water returner housing 1, it is convenient to wirelessly connect the hand-held remote controller 4, the wall-mounted remote controller 5, and the doorbell wire control switch 6 to the water returner housing 1, so that the device has the advantages of optional control methods, more convenient and practical operation, and is easy to promote. In addition, by bonding damping vibration-absorbing and sound-absorbing felts 18 on the inner side walls of the water returner housing 1 and the back plate 8, the buffering and sound absorption and noise reduction effects of the inner walls of the water returner housing 1 and the back plate 8 are improved, which is beneficial to reducing the noise pollution caused by the operation of the DC circulation pump 10 and the vibration impact on the water returner housing 1. And by uniformly arranging honeycomb-shaped sound-absorbing holes 21 on the damping vibration-absorbing and sound-absorbing felts 18, during use, when sound energy passes through the honeycomb-shaped sound-absorbing holes 21, it excites the air vibration inside the hole structure to continuously convert the kinetic energy of the air into heat energy to attenuate the sound energy, thereby improving the sound absorption performance of the damping vibration-absorbing and sound-absorbing felts 18. Moreover, nano-titanium dioxide self-cleaning layers 19 are coated on the outer side walls of the water returner housing 1 and the back plate 8, improving the anti-pollution and corrosion resistance of the outer wall of the device.
