Technical Field
[0001] This utility model relates to a constant temperature, high efficiency and continuous boiling water output device. Background Technology
[0002] Instant hot water dispensers are water dispensers that can dispense boiling water in a few seconds or tens of seconds. The key to their ability to quickly dispense hot water lies in the internal boiling water dispensing device. At present, the boiling water dispensing devices on the market are usually balanced water dispensing devices, which use a heating element to quickly heat the water to achieve the purpose of quickly dispensing boiling water. However, the large amount of high-temperature steam generated during the water heating process of the boiling water dispensing devices on the market is not effectively recovered and utilized.
[0003] Therefore, it is necessary to make further improvements. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a constant temperature, high efficiency and continuous boiling water output device, which is equipped with a preheating chamber for recovering the heat of high temperature steam.
[0005] To achieve the above objectives, this utility model provides a constant-temperature, high-efficiency, continuous boiling water output device, which includes a water storage tank, a preheating chamber, a balance tank, a pump body, a three-way valve, and a heater. The preheating chamber is equipped with a preheating pipeline, and the balance tank is equipped with a mechanical float valve. The outlet end of the water storage tank is connected to the input end of the pump body. The two ends of the preheating pipeline are respectively connected to the mechanical float valve and the output end of the pump body.

The first end of the three-way valve is connected to one side of the preheating chamber, the second end of the three-way valve is connected to the water storage tank, and the third end of the three-way valve is the water outlet.
[0006] In one or more embodiments, the output end of the pump body is connected to a one-way valve, which is connected to a preheating pipeline via a first water pipe.
[0007] In one or more embodiments, the preheating pipeline is spiral-shaped, with both ends extending out of the preheating chamber.
[0008] In one or more embodiments, the preheating chamber is located on one side of the balance box, and a guide pipe is provided on the side of the preheating chamber corresponding to the balance box.

This heat energy recycling design not only improves the equipment's energy efficiency but also optimizes the user experience. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the boiling water device in this embodiment; Figure 2 This is a cross-sectional view of the boiling water apparatus in this embodiment; Figure 3 This is a partially enlarged cross-sectional view of the boiling water device located at the three-way valve in this embodiment. Detailed Implementation
[0016] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0017] Please refer to the appendix. Figure 1 and 2This application provides a constant temperature, high efficiency, and continuous boiling water output device, which includes a water storage tank 1, a preheating chamber 2, a balance tank 3, a pump body 4, a three-way valve, and a heater. The preheating chamber 2 is equipped with a preheating pipe 5, which is specifically spiral-shaped to provide a large heat exchange area and fully recover and utilize high-temperature steam. Both ends of the preheating pipe 5 extend out of the preheating chamber 2. The balance tank 3 is equipped with a mechanical float valve 6, which is a conventional structure currently available on the market. The mechanical float valve can be adjusted to regulate the flow rate by adjusting its height. Lowering the height of the mechanical float valve can reduce the flow rate, thereby increasing the outlet water temperature, while raising the height of the mechanical float valve can increase the flow rate, thereby decreasing the outlet water temperature.
[0018] The outlet of the water storage tank 1 is connected to the input of the pump body 4. The two ends of the preheating pipe 5 are connected to the mechanical float valve 6 and the output of the pump body 4, respectively. The top of the heater is the outlet and is connected to the preheating chamber 2. The bottom of the heater is the inlet and is connected to the balance tank 3. Specifically, the bottom of the balance tank 3 is connected to a second water pipe 14, which is connected to the inlet of the heater. One side of the preheating chamber 2 is connected to the first end of a three-way valve. The second end of the three-way valve is connected to the water storage tank 1, and the third end of the three-way valve is the outlet 7. In use, the heated water can be circulated through the second end of the three-way valve into the water storage tank 1 by controlling the three-way valve, thus achieving zero cold water output. After the second end of the three-way valve is closed, the boiled water heated by the heater can be directly output from the outlet 7 for user use.
[0019] The output end of the pump body 4 is connected to a one-way valve 8. The one-way valve 8 is connected to the preheating pipeline 5 through the first water pipe 9. The one-way valve 8 can ensure that there is water in the first water pipe 9 when the pump body 4 is not working, and ensure that the balance box 3 is replenished with water in time when water is needed.
[0020] The preheating chamber 2 is located on one side of the balance box 3. The preheating chamber 2 is provided with a guide pipe 10 on the same side of the balance box 3. The balance box 3 has an opening for the guide pipe 10 to extend into. The guide pipe 10 is sealed to the opening. The preheating chamber 2 and the balance box 3 are connected through the guide pipe 10, so that high-temperature steam can enter the balance box and avoid negative pressure in the preheating chamber from affecting the smoothness of water output.
[0021] The heater includes a heater housing 11 and a heating element 12 disposed inside the heater housing 11. The bottom of the heater housing 11 is a mounting port, through which the heating element 12 is inserted into the heater housing 11. The heating element 12 is provided with a flange that seals with the mounting port. Traditional heating elements can be used, eliminating the need for customization and enhancing product versatility. The heating element can be made of copper or stainless steel, depending on actual needs. Furthermore, the heating element 12 is placed vertically, resulting in a longer service life compared to horizontal placement. Vertical placement also reduces scale buildup, and the welding points of the heating wire remain in a low-temperature zone, making it less prone to burnout.
[0022] The heater is equipped with a thermostat 13. When the temperature reaches the preset temperature of the thermostat 13, the power supply to the heating element 12 is disconnected. The thermostat can protect the heater and the product in case of dry burning or abnormal temperature rise. To prevent heat loss, the heater housing 11 is covered with a heat insulation layer.
[0023] See appendix Figure 3 The three-way valve includes a three-way valve seat 15, a valve stem 16, a suction cup 17, and an electromagnetic coil 18. The first end of the three-way valve seat 15 is connected to the preheating chamber 2, and the second end of the three-way valve seat 15 is connected to the water storage tank 1. The valve stem 16 is connected to the electromagnetic coil 18, and the suction cup 17 is connected to the valve stem 16 and is located on the second end of the three-way valve seat 15. The valve stem is driven to move by the electromagnetic coil 18, so that the suction cup 17 closes or opens the second end of the three-way valve seat 15. The suction cup 17 has better sealing performance than the traditional flat seal.
