Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to a dual-outlet instant hot water dispenser. Background Technology

[0002] Currently, the functions of water dispenser products are constantly being upgraded, and the market penetration rate of wall-mounted instant hot water dispensers continues to rise. However, due to the influence of heating power, the water flow rate is small, which affects the customer's user experience.

[0003] Instant hot water dispensers now offer multiple temperature settings, such as room temperature, 45℃, 55℃, 85℃, and 100℃. For daily drinking needs, room temperature and low temperature water are used more frequently in fast-paced life and office settings.

[0004] According to the law of conservation of energy, under the same power, the lower the water temperature, the greater the flow rate should be. However, current water dispensers on the market are designed with high-temperature water outlets in mind, sharing hot and cold water pipes. This means that the flow rate of cold water is limited to the flow rate of hot water. For example, a 2.2kW heating element can only boil 500ml of water per minute. The outlet channel (water-air separator) is designed for 500ml. If the cold water flow rate increases, this channel cannot drain the water in time, causing the water level to rise and eventually overflow from the vent, thus limiting the flow rate at low temperatures. In reality, cold water does not need to be heated, so the flow rate can be increased. Therefore, for heating drinking water with the same power, the lower the required water temperature, the greater the flow rate should be. Summary of the Invention

[0005] To address the aforementioned issues, the purpose of this invention is to provide a dual-outlet instant hot water dispenser that solves the problem of low water flow rate in the low-temperature section of the instant hot water dispenser. By working in tandem with dual pipelines, the water flow rate in the low-temperature section is increased.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dual-outlet instant hot water dispenser includes a water tank. The inlet end of the water tank is connected to a pure water machine via an inlet pipe. A first inlet solenoid valve is installed on the inlet pipe. The outlet end of the water tank is connected to the inlet end of a heating element via an outlet pipe. A water pump is installed on the outlet pipe. The outlet end of the heating element is connected to a water vapor separator via a hot water pipe. A hot water outlet is provided at the lower end of the water vapor separator, extending longitudinally out of the surface of the water dispenser. The dispenser is characterized in that a direct current pipe is connected between the first inlet solenoid valve and the pure water machine on the inlet pipe. A room temperature water outlet is provided at the other end of the direct current pipe. A second inlet solenoid valve is installed on the direct current pipe. The room temperature water outlet extends out of the surface of the water dispenser and is close to the hot water outlet.

[0007] Preferably, a pressure reducing valve is provided on the DC pipeline between the second inlet solenoid valve and the ambient temperature water outlet.

[0008] Preferably, a check valve is provided on the DC pipeline between the pressure reducing valve and the ambient temperature water outlet.

[0009] Preferably, the bottom of the room temperature water outlet is flush with the bottom of the hot water outlet.

[0010] Preferably, the water pump is a diaphragm pump.

[0011] Preferably, a high-level liquid level sensor and a low-level liquid level sensor are respectively provided on the upper and lower parts of the inner side of the water tank.

[0012] The present invention adopts the above technical solution and has the following beneficial effects: ① This solution adds an extra DC pipeline to the outlet of the pressurized water purifier, with a room temperature water outlet at the other end of the DC pipeline. That is, in the original water vapor separator structure, an extra room temperature water outlet is added to the outlet. In this way, when room temperature water is needed, the second solenoid valve can be opened, and the pressurized water purifier can directly supply water to the room temperature water outlet through the DC pipeline, shortening the water waiting time and reducing drinking water time costs (the room temperature water flow rate of a conventional pipeline machine is 0.4L / min; the room temperature water flow rate of this system can reach 2.1L / min, and the water output speed can be increased by 5 times).

[0013] ② Normal temperature water output eliminates the need for a water pump, reducing pump operating time and extending the overall lifespan of the machine.

[0014] ③ Hot water and ambient water pipes are separated, hot and cold water are diverted, simplifying the heating system structure and ensuring system stability.

[0015] ④ Hot water and ambient temperature water pipes are separated, and hot and cold water are diverted. The high-temperature water pipes can be sterilized at high temperatures to ensure system hygiene; while the ambient temperature water pipe outlet is equipped with a check valve to prevent bacteria and viruses from entering the system and ensure system hygiene.

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] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figures 1-3The illustrated dual-outlet instant hot water dispenser includes a water tank 1. The inlet end of the water tank 1 is connected to a pure water machine 3 via an inlet pipe 2. A first inlet solenoid valve 4 is provided on the inlet pipe 2. The outlet end of the water tank 1 is connected to the inlet end of a heating element 6 via an outlet pipe 5. A water pump 7 is provided on the outlet pipe 5. The outlet end of the heating element 6 is connected to a water vapor separator 9 via a hot water pipe 8. A hot water outlet 10 is provided at the lower end of the water vapor separator 9, extending longitudinally out of the surface of the water dispenser. A direct current pipe 11 is connected between the first inlet solenoid valve 4 and the pure water machine 3 on the inlet pipe 2. A room temperature water outlet 12 is provided at the other end of the direct current pipe 11. A second inlet solenoid valve 13 is provided on the direct current pipe 11. The room temperature water outlet 12 extends out of the surface of the water dispenser and is close to the hot water outlet 10.

[0025] In the above technical solution, an additional ambient temperature water outlet is added to the original water vapor separator structure. Specifically, an additional direct current pipe is installed at the outlet of the pressurized water purifier, and an ambient temperature water outlet is installed at the other end of the direct current pipe. That is, an outlet is added next to the outlet of the water vapor separator. In this way, when ambient temperature water is needed, the second solenoid valve can be opened, and the pressurized water purifier can directly supply water to the ambient temperature water outlet through the direct current pipe, shortening the waiting time for water and reducing drinking water time costs (the ambient temperature water flow rate of a conventional pipeline machine is 0.4L / min; the ambient temperature water flow rate of this system can reach 2.1L / min, and the water output speed can be increased by 5 times).

[0026] Furthermore, the water at room temperature is dispensed using the pressure from the pure water machine, eliminating the need for a water pump and reducing pump operating time, thus extending the overall lifespan of the machine.

[0027] In addition, hot water and ambient water pipes are separated, and hot and cold water are diverted, simplifying the heating system structure and ensuring system stability.

[0028] Furthermore, a pressure reducing valve 14 is provided on the DC pipe 11 between the second inlet solenoid valve 13 and the room temperature water outlet 12. In this technical solution, the pressure reducing valve ensures that the drinking water from the water purifier maintains a stable pressure and flow rate after passing through the pressure reducing valve, thus ensuring the stability of the water output from the room temperature water outlet.

[0029] Furthermore, a check valve 15 is provided on the DC pipe 11 between the pressure reducing valve 14 and the ambient temperature water outlet 12. In this technical solution, the check valve prevents backflow of water, thereby avoiding the growth of bacteria and water pollution in the pipe caused by backflow.

[0030] Furthermore, the lower ends of the room temperature water outlet 12 and the hot water outlet 10 are flush. In this technical solution, when producing warm water, the room temperature water outlet is close to the hot water outlet and their lower ends are flush, ensuring that the room temperature water and hot water fall from the same height, which facilitates the mixing of the room temperature water and hot water in the water intake container.

[0031] Furthermore, the water pump 7 is a diaphragm pump.

[0032] Furthermore, a high-level liquid level sensor 16 and a low-level liquid level sensor 17 are respectively provided on the upper and lower parts of the inner side of the water tank 1.

[0033] In this specific embodiment, addressing the issue of low water flow rate in the low-temperature section of existing wall-mounted instant hot water dispensers, the above solution adds an extra direct current pipe to the outlet end of the pressurized water purifier. The other end of this direct current pipe is equipped with a room temperature water outlet. That is, within the existing water vapor separator structure, an additional room temperature water outlet is added to the outlet end. Thus, when room temperature water is needed, the second solenoid valve can be opened, and the pressurized water purifier directly supplies water to the room temperature outlet through the direct current pipe, shortening the waiting time for water and reducing drinking water time costs (conventional pipeline water dispensers have a room temperature water flow rate of 0.4 L / min; this system can achieve a room temperature water flow rate of 2.1 L / min, increasing the water flow rate by 5 times).

[0035] 2. Room temperature water production: 1) Select the water volume; 2) Select the room temperature drinking water setting and press the water dispensing button; 3) The second inlet solenoid valve opens; 4) The drinking water passes through the pressure reducing valve to stabilize the pressure and flow rate; 5) It passes through the check valve to prevent bacteria and viruses from entering the pipeline system when the water is not in use; 6) The drinking water flows out from the room temperature water outlet; 7) When the water volume reaches the set amount, the control system closes the second inlet solenoid valve; the operation ends.

[0036] 3. Warm Water Production: 1) Select water volume; 2) Select the corresponding warm water temperature setting; 3) The control system adjusts the drinking water to the corresponding temperature according to the mixing ratio of high-temperature and room-temperature drinking water, calculates the output volume and corresponding output time of high-temperature and room-temperature drinking water, and outputs instructions; 4) The first inlet solenoid valve opens, the diaphragm pump starts, and the heating element begins to work; 5) When the room-temperature drinking water reaches the set output volume, the second inlet solenoid valve opens and closes; 6) When the high-temperature drinking water reaches the set output volume, the water pump and heating element stop working; 7) The high-temperature and room-temperature drinking water mix in the water dispensing container to reach the set temperature.

High-temperature direct drinking water production: 1) Select water volume; 2) Select high-temperature direct drinking water setting and press the water dispensing button; 3) The diaphragm pump starts and the heating element works; 4) High-temperature direct drinking water flows out from the water outlet of the water vapor separator box; 5) When the water volume reaches the set volume, the control system executes an action to stop the diaphragm pump and the heating element.
