Description

Technical Field

[0001] This utility model relates to the technical field of water purification systems, and in particular to a constant flow stepless temperature-regulating water purifier outlet device. Background Technology

[0002] The water temperature and flow rate of household water purifiers are key concerns; inaccurate flow rates can lead to overflows and insufficient water supply. Most heated water purifiers on the market use instant heating, adjusting pump flow rate and heating power to achieve a certain range of water temperature variations. However, seasonal changes in raw water temperature and the impact of mains voltage on heating power further exacerbate the uncontrollability of the water temperature. Furthermore, these products typically adjust temperature by increasing or decreasing the flow rate, resulting in flow rate uncertainty. Summary of the Invention

[0006] The technical problem to be solved by this utility model can also be further achieved through the following technical solution: the faucet is provided with a mixing chamber and two inlets and one outlet connected to the mixing chamber. The two inlets are respectively connected to the cold water pipe and the hot water pipe.

[0007] The technical problem to be solved by this utility model can also be further achieved through the following technical solution: the water outlet assembly includes a cold water tank and a hot water tank.

[0014] The specific technical solutions of the present invention are further described below. To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, and to facilitate a better understanding of the present invention by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments, and do not constitute a limitation on its rights. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0015] A constant flow stepless temperature-regulating water purifier outlet device includes an outlet component 1 and a faucet 2. The outlet component and the faucet are connected by a cold water pipe and a hot water pipe. A cold water outlet pump 6 is installed on the cold water pipe, and a hot water outlet pump 11 is installed on the hot water pipe. The water temperature of the faucet is controlled by adjusting the speed and start / stop time of the cold water outlet pump and the hot water outlet pump.

[0016] Both the cold water outlet pump and the hot water outlet pump are variable frequency centrifugal pumps.

[0017] The water outlet assembly includes a cold water tank 3 and a hot water tank 7. The cold water tank is equipped with a cold water temperature sensor 4 and a cold water level sensor 9, and is connected to the cold water pipe of the faucet. The hot water tank is equipped with a hot water temperature sensor 8, a hot water level sensor 9, and a heating element 10, and is connected to the hot water pipe of the faucet.

[0018] The cold water temperature sensor and the hot water temperature sensor are connected to the controller 15. The controller collects the temperature of the water in the cold water tank and the hot water tank through the cold water temperature sensor and the hot water temperature sensor, and then adjusts the speed of the cold water outlet pump and the hot water outlet pump.

[0019] The faucet has a mixing chamber 13, and two inlets and one outlet 14 connected to the mixing chamber. The two inlets are connected to the cold water pipe and the hot water pipe, respectively. The faucet also has an exhaust port 12, which is connected to the cold water tank and the hot water tank through an exhaust pipe, so as to play the role of venting and breathing with the water storage tank.

[0020] The specific structure is shown in the figure: The water purifier's temperature-controlled water outlet device includes a hot water tank 7 and a cold water tank 3, which hold hot water and cold water respectively. The hot water tank 7 contains a hot water temperature sensor 8, a hot water level sensor 9, and a heating element 10. The hot water tank 7 is connected to a hot water pump 11. The cold water tank 3 contains a cold water temperature sensor 4 and a cold water level sensor 5. The cold water tank 3 is connected to a cold water pump 6. Both the cold water pump and the hot water pump have adjustable speeds.

[0021] When a user draws cold water, the cold water level is above the middle level, the cold water pump starts at full speed, the hot water pump is turned off, and the tap supplies cold water.

[0022] When a user needs hot water: the hot water level is above the middle level, the hot water pump starts at full speed, the cold water pump is turned off, and the faucet supplies hot water.

[0023] When a user needs water at a certain temperature, the hot water temperature in hot water tank 7 and the cold water temperature in cold water tank 3 remain constant. Therefore, based on the temperatures measured by cold water temperature sensor 4 and hot water temperature sensor 8, the required outlet water temperature varies. The pipe volume from the cold water outlet pump and the hot water outlet pump to the faucet is also constant. By adjusting the speed and start-up time of the cold water outlet pump and the hot water outlet pump, the accuracy of the outlet water temperature and the stability of the outlet water flow can be ensured.

[0024] Rejecting stagnant water that doesn't meet the required temperature: According to the water circuit diagram, the pipes from the cold water pump and hot water pump to outlet 14 are unobstructed. Cold and hot water mix in the faucet's inner cavity 13 to reach the desired temperature before being supplied to the user. If water remains in this section of the pipe, it will not only cause occasional dripping from the faucet, but also result in lower water temperatures due to thermal expansion and contraction, vibration, etc., especially when the user only needs a cup of water. Therefore, both the cold water pump and the hot water pump are variable frequency centrifugal pumps. When the pump stops, the cold and hot water flow back to the cold water tank 3 or the hot water tank 7, respectively, ensuring that the temperature of the water pumped out by the cold and hot water pumps after the pump starts is consistent with the temperature measured by the cold water temperature sensor 4 or the hot water temperature sensor 8.
