Description

Technical Field

[0001] This utility model belongs to the technical field of integrated water purifier and heat pump, specifically a hot water outlet and exhaust structure. Background Technology

[0002] In existing integrated water purifiers and heaters, the heating tank is used to store and heat water. The heating element inside the tank boils the water and then maintains the temperature. When the water pump in the integrated water purifier and heater draws water from the heating tank, especially immediately after the tank has boiled the water, the pump impeller drives the hot water to rotate at high speed. According to Bernoulli's equation, the water pressure decreases, falling below the external atmospheric pressure, causing the boiling point of the water to drop. Due to the lower boiling point, the water may vaporize, forming bubbles and causing air blockage in the pump. This leads to a reduced water flow or even no water output, severely impacting user experience and equipment reliability. Current technologies typically employ complex gas-liquid separation devices or additional venting valves to address the air blockage problem. However, these solutions are often complex in structure, expensive, and have limited venting efficiency, failing to completely eliminate air blockage. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a hot water outlet and exhaust structure.

[0004] The technical solution adopted by this utility model is as follows: a hot water outlet and venting structure, including a hot tank and a water pump, wherein the upper and lower ends of the hot tank are respectively provided with a hot tank inlet and a hot tank outlet connected thereto, wherein the hot tank outlet is connected to the water inlet of the water pump, and the water outlet of the water pump is connected to a hot water outlet pipe, wherein the hot water outlet pipe and the water outlet are both arranged facing upwards, and the top of the hot water outlet pipe extends upwards to form an venting pipe section connected to the hot tank inlet.

[0005] In a preferred embodiment, the hot water outlet pipe has an outlet pipe section connected to the hot water outlet pipe on its side, and the outlet pipe section is positioned lower than the vent pipe section.

[0006] In a preferred embodiment, the inlet of the hot water tank is provided with a T-connector connected thereto, and the remaining two ports of the T-connector are respectively connected to the exhaust pipe section and the water supply pipe.

[0007] In a preferred embodiment, a one-way valve is provided at the connection between the exhaust pipe section and the three-way connector, and the direction of the one-way valve is consistent with the delivery direction of the exhaust pipe section.

[0008] In a preferred embodiment, the water pump is an impeller pump.

[0009] In a preferred embodiment, the top of the hot tank is also provided with an exhaust pipe connected thereto.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: by setting both the hot water outlet pipe and the water pump outlet interface upward, and extending the hot water outlet pipe upward to form an exhaust pipe section connected to the inlet of the hot water tank, the gas can rise and be discharged naturally under the buoyancy of the water and the large flow of water, effectively preventing air blockage caused by vaporized bubbles in the water pump, ensuring stable water flow. The whole solution is achieved by optimizing the pipe layout and exhaust design, reducing the number of components required to solve the air blockage problem in the traditional way. The structure is simple and the overall manufacturing cost is also reduced. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1-2 A hot water outlet and venting structure includes a hot water tank 100 and a water pump 200. The hot water tank 100 has a hot water inlet 120 and a hot water outlet 110 at its upper and lower ends, respectively, which are connected to each other. The hot water outlet 110 is connected to the inlet of the water pump 200. The outlet 210 of the water pump 200 is connected to a hot water outlet pipe 300. Both the hot water outlet pipe 300 and the outlet 210 are upward-facing. The top of the hot water outlet pipe 300 extends upward to form a vent that communicates with the hot water inlet 120 of the hot water tank. The air vent section 320 has both the hot water outlet pipe 300 and the water outlet interface 210 of the water pump 200 facing upwards. The hot water outlet pipe 300 is extended upwards to form an air vent section 320 that connects to the water inlet 120 of the hot water tank. This allows the gas to rise and be discharged naturally under the buoyancy of the water and the large flow of water, effectively preventing air blockage caused by vaporized bubbles in the water pump 200 and ensuring a stable water flow. The whole solution is achieved by optimizing the pipe layout and the air vent design. The structure is simple and the overall manufacturing cost is reduced.

[0023] Specifically, the water pump 200 is an impeller pump. The design of the impeller pump combined with the hot water outlet pipe 300 increases the volume of the channel after the pump and improves the liquid flow rate through the water pump 200, thereby more effectively removing trapped air from the water pump 200 and enhancing the system's venting capacity and operational stability.

[0024] In this embodiment, please refer to Figure 1 As shown, the hot water outlet pipe 300 has an outlet pipe section 310 connected to it on the side. The outlet pipe section 310 is positioned lower than the exhaust pipe section 320, which allows hot water to flow out from the side outlet pipe section 310 first, while the gas continues to rise to the exhaust pipe section 320 and is discharged. This achieves gas-liquid separation, further optimizes the exhaust and water discharge process, and improves system efficiency.

[0025] In this embodiment, a T-joint 400 is provided on the hot water inlet 120 of the hot tank and is connected thereto. The remaining two ports of the T-joint 400 are respectively connected to the exhaust pipe section 320 and the water supply pipe 500. The above design simplifies the pipe connection structure, reduces the number of components, reduces the installation complexity, and at the same time maintains the compactness and reliability of the system.

[0026] In this embodiment, please refer to Figure 1As shown, a one-way valve 330 is provided at the connection between the exhaust pipe section 320 and the three-way connector 400. The direction of the one-way valve 330 is consistent with the delivery direction of the exhaust pipe section 320. The designed one-way valve 330 can effectively prevent water from flowing back to the hot water outlet pipe 300 when the hot tank is replenished, thus avoiding water waste and potential pollution, and ensuring the one-way flow characteristics of the system.

[0027] In this embodiment, please refer to Figure 2 As shown, the top of the hot tank 100 is also equipped with an exhaust pipe 130 connected to it. The exhaust pipe 130 is connected to the atmosphere, so that the hot tank 100 can be ventilated with the atmosphere during the process of adding water, boiling water and discharging water, so as to avoid the problem of internal pressure expansion or negative pressure in the hot tank 100.

[0028] In other embodiments, the exhaust pipe section 320 may also be directly connected to the exhaust pipe 130, and the gas may be discharged directly through the exhaust pipe 130.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
