Description

Technical Field

[0001] This utility model relates to the field of water heaters, and in particular to a water circuit system and an electric water heater. Background Technology

[0002] Electric water heater is a Electric water heaters are household appliances capable of heating and supplying domestic hot water. However, existing water system designs for electric water heaters still have some shortcomings, mainly in terms of water replenishment and hot water supply capacity. These systems generally lack a water replenishment function or, if they do, the replenishment effect is poor. Furthermore, relying on a single heating circuit results in a limited hot water supply, failing to meet users' demands for a larger volume of hot water. Utility Model Content

[0003] Therefore, it is necessary to provide a water system and electric water heater to address the problems that water systems generally do not have a water replenishment function or have a water replenishment function but the water replenishment effect is poor, and that a single heating water circuit results in a small supply of hot water.

[0004] A water system includes: a water tank assembly having a liquid storage chamber, a vent, and a water inlet, both of which are connected to the liquid storage chamber; a water delivery assembly disposed on the water tank assembly and located within the liquid storage chamber; a heating module disposed on or adjacent to the water tank assembly; a water outlet structure connected to both the heating module and the water delivery assembly; and a water replenishment assembly disposed on the water tank assembly and connected to the water inlet.

[0005] The first aspect of this application discloses a water system that connects to a liquid storage chamber via a vent. This vent allows direct connection to the external atmosphere, balancing the air pressure within the liquid storage chamber and preventing steam buildup that could hinder water replenishment or interrupt water flow, thus ensuring a stable and efficient water replenishment process. This design enhances product safety. The vent can also connect directly to a water replenishment component, allowing steam to enter and condense. The water replenishment component connects to a water inlet, ensuring that the condensed water can re-enter the liquid storage chamber to replenish the liquid. This design significantly improves water resource utilization, avoids water waste caused by direct steam discharge, maintains a stable water level in the storage chamber, effectively reduces rapid scale formation due to sudden water volume reduction, and extends equipment lifespan. The water delivery component heats the water flow within the storage chamber using a water bath, preventing impurity accumulation and improving the cleanliness of the output water. By adding a heating module, an additional hot water circuit can be added to the traditional hot water circuit, effectively increasing the hot water output. Furthermore, the heating module can rapidly heat cold water, significantly reducing the waiting time for users to receive hot water. Through the coordinated functions of water replenishment, water supply, heating, and water output, the water system of this application can achieve a continuous and stable hot water supply, providing ample hot water flow and enhancing the user experience.

[0006] In one embodiment, a water inlet structure is also included, which is connected to the water tank assembly. By directly connecting the water inlet structure to the water tank assembly, an intermediate transfer link is eliminated, making the water replenishment path more direct and efficient, reducing water flow resistance, and improving water replenishment efficiency.

[0007] In one embodiment, the water inlet structure is connected to the water delivery component. By directly connecting the water inlet structure to the water delivery component, a continuous supply of cold water is provided to the water delivery component. The cold water in the water delivery component is heated by a hot water bath in the storage chamber, thereby providing the user with a continuous supply of hot water.

[0008] In one embodiment, the water inlet structure is connected to the heating module. This connection provides the heating module with ample cold water, enabling it to heat and output the cold water. This design adds a hot water path to the traditional hot water path, significantly increasing the overall hot water supply of the system.

[0009] In one embodiment, the water inlet structure is connected to the water replenishment component. This connection between the water inlet structure and the water replenishment component makes the water replenishment process more efficient and controllable, reduces water flow resistance, and ensures rapid and stable water replenishment to the storage chamber.

[0010] In one embodiment, the water outlet structure includes a first valve body and an outlet pipe. The water inlet structure, the water delivery component, the first valve body, and the outlet pipe are sequentially connected to form a first hot water path. Through the sequential connection of the water inlet structure, the water delivery component, the first valve body, and the outlet pipe to form the first hot water path, cold water passing through the water delivery component gradually heats up under the heating of the hot water bath in the storage chamber to form hot water output. The hot water only flows through the water delivery component, preventing impurity accumulation and improving the cleanliness of the output water. Preferably, the first valve body is a thermostatic valve used to control the proportion of water entering the thermostatic valve from the two hot water paths, thereby outputting water at a constant temperature.

[0011] In one embodiment, the inlet structure, the heating module, the first valve body, and the outlet pipe are sequentially connected to form a second hot water circuit. The first valve body controls the ratio of hot water entering the first and second hot water circuits, effectively regulating the output flow of hot water to meet users' different hot water supply needs.

[0012] In one embodiment, a first connecting pipe is also included, and the water inlet structure, the water delivery component, the first connecting pipe, the first valve body, and the water outlet pipe are sequentially connected to form a first hot water circuit. The first connecting pipe ensures that the water delivery component can communicate with the first valve body to deliver hot water, resulting in high efficiency in hot water delivery.

[0013] In one embodiment, a second connecting pipe is also included, and the water inlet structure, the heating module, the second connecting pipe, the first valve body, and the water outlet pipe are sequentially connected to form a second hot water circuit. The second connecting pipe ensures that the heating module is connected to the first valve body for hot water delivery, guaranteeing smooth hot water output.

[0014] In one embodiment, the water replenishment assembly includes a water replenishment tank and a water replenishment pipe. The water replenishment tank is mounted on the water tank assembly and has a receiving space. The water replenishment pipe is connected to both the water replenishment tank and the water tank assembly. The structural design of the water replenishment tank and water replenishment pipe creates a smooth water replenishment channel, ensuring sufficient liquid in the storage chamber and improving heat exchange efficiency. The receiving space of the water replenishment tank can effectively collect and temporarily store steam condensate, which flows back to the water tank assembly through the water replenishment pipe, improving water resource utilization and reducing waste.

[0015] In one embodiment, the liquid storage chamber, the vent, the receiving space, the water supply pipe, and the water supply inlet are sequentially connected to form a first water supply path. This sequential connection of the liquid storage chamber, vent, receiving space, water supply pipe, and water supply inlet creates a complete first water supply path, achieving a closed-loop circulation of condensate from steam treatment and water supply, significantly improving water resource utilization. The vent's connection to the water supply path ensures dynamic balance between the internal air pressure of the liquid storage chamber and the water supply tank, preventing steam accumulation that could hinder water supply and ensuring stable operation of the water supply path.

[0016] In one embodiment, a water inlet structure is further included. The water inlet structure, the accommodating space, the water supply pipe, and the water supply inlet are sequentially connected to form a second water supply path. By introducing an external water source through the water inlet structure, the accommodating space, the water supply pipe, and the water supply inlet, the second water supply path can replenish the liquid in the storage chamber when it is insufficient, ensuring sufficient liquid in the storage chamber, improving heat exchange efficiency, and enabling the cold water in the water supply assembly to be quickly converted into hot water.

[0017] In one embodiment, the accommodating space includes a condensation chamber and a flow chamber. The water replenishment component is provided with a first output port. The liquid storage chamber, the vent, the condensation chamber, the flow chamber, the first output port, the water replenishment pipe, and the water replenishment inlet are sequentially connected to form a first water replenishment path. Through the partitioned design of the condensation chamber and the flow chamber, steam condenses in the condensation chamber to form condensate, which then flows orderly into the flow chamber and is finally transported back to the liquid storage chamber, improving condensate recovery efficiency and reducing water waste.

[0018] In one embodiment, a water inlet structure is further included. The water inlet structure, the flow chamber, the first outlet, the water supply pipe, and the water supply port are sequentially connected to form a second water supply path. Through the connection between the water inlet structure and the flow chamber, water from the outside is directly transported to the liquid storage chamber via the flow chamber, ensuring sufficient liquid in the liquid storage chamber and providing a guarantee for water bath heating.

[0019] In one embodiment, a pressure relief pipe is also included. The water supply component has a second outlet, and the receiving space, the second outlet, and the pressure relief pipe are sequentially connected to form a pressure relief water path. Because the receiving space, the second outlet, and the pressure relief pipe are connected in sequence, when there is too much liquid or excessive air pressure in the receiving space, it can be discharged through the pressure relief pipe, ensuring the safety of the equipment.

[0020] In one embodiment, the water inlet structure includes a first water inlet pipe, a second water inlet pipe, and a water inlet assembly. The first water inlet pipe is connected to the water supply assembly, the second water inlet pipe is connected to the heating module, and the water inlet assembly is connected to the water replenishment assembly. Both the second water inlet pipe and the water inlet assembly are connected to the first water inlet pipe. Through the division of labor and cooperation among the first water inlet pipe, the second water inlet pipe, and the water inlet assembly, the water supply to the water supply assembly, heating module, and water replenishment assembly can be regulated, ensuring sufficient water supply for each functional module without interference.

[0021] In one embodiment, the second water inlet pipe is connected to the first water inlet pipe, and the water inlet assembly is connected to the second water inlet pipe. By connecting the second water inlet pipe to the first water inlet pipe and the water inlet assembly to the second water inlet pipe, pipe materials can be effectively saved, production costs reduced, and economic efficiency improved.

[0022] In one embodiment, the water inlet assembly includes a third water inlet pipe, a second valve body, and a fourth water inlet pipe. The third water inlet pipe is connected to the second water inlet pipe, and the third water inlet pipe, the second valve body, and the fourth water inlet pipe are sequentially connected. The fourth water inlet pipe is connected to the water replenishment assembly. By adjusting the flow rate from the third water inlet pipe to the fourth water inlet pipe through the second valve body, water can be supplied to the water replenishment assembly on demand, avoiding excessive water replenishment that could lead to abnormal water levels.

[0023] An electric water heater includes: a housing assembly; and the aforementioned water circuit system, wherein the water circuit system is disposed on the housing assembly.

[0024] The second aspect of this application discloses an electric water heater with a dual-water-circuit design, including a first hot water circuit and a second hot water circuit, which operate independently through a water delivery component and a heating module, respectively, significantly improving the hot water output. A vent is connected to the liquid storage chamber to balance internal pressure and prevent steam accumulation that could lead to abnormal pressure or poor water supply. The water supply component allows steam generated during heating to be directed to the component for condensation, with the condensate flowing back to the liquid storage chamber, achieving water resource recycling and reducing waste.
