[0001] The utility model relates to the field of various household water-using electrical appliances, in particular to a multifunctional hot and cold water treatment device. Background Art

[0002] A water dispenser is a device that heats or cools bottled purified water (or mineral water) for convenient drinking. The dispenser is placed on top of the bottled water dispenser and is used in conjunction with the dispenser. Water dispensers are generally categorized into three types: warm water dispenser, ice-hot water dispenser, and ice-warm water dispenser. Ice-hot water dispensers are further divided into semiconductor-cooled dispensers and compressor-cooled dispensers. Furthermore, kitchens, dining rooms, and living rooms require a variety of water needs, such as washing and drinking hot and cold water. In typical products, washing and drinking water dispensers are separate. Simply integrating these two components is costly and inconvenient. A product with more comprehensive functionality, meeting diverse water needs, reducing electrical footprint, and lowering power consumption is lacking. Utility Model Content

[0015] Example 1: Figures 1-4As shown, a multifunctional hot and cold water treatment device includes a body 1, a water outlet faucet of a master control solenoid valve is provided at the upper end of the body 1, a water inlet pipe 2 and a connected filtering device 3 are provided in the body 1, and a direct drinking main pipe 4 and a washing main pipe 5 are led out of the filtering device 3. The end of the direct drinking main pipe 4 is connected to a cold direct drinking branch pipe 6 and a hot direct drinking branch pipe 7, the cold direct drinking branch pipe 6 is further provided with a first solenoid valve 8, the hot direct drinking branch pipe 7 is further provided with a second solenoid valve 9, the end of the hot direct drinking branch pipe 7 is provided with an insulation liner 10 and a coil 11 connected to the hot direct drinking branch pipe 7, the coil 11 extends into the interior of the insulation liner 10, and the end of the coil 11 extends out of the insulation liner 10. The inner tank 10 is connected to the water outlet faucet, and a third solenoid valve 12 is provided at the main wash pipe 5. The end of the main wash pipe 5 is connected to a water supply branch pipe 13 and a wash branch pipe 14. The outlet of the end of the water supply branch pipe 13 is provided with an insulated outer tank 23 that wraps the insulated inner tank 10. The wash branch pipe 14 is also provided with a flow solenoid valve 16. The end of the wash branch pipe 14 is connected to the water outlet faucet, and the wash branch pipe 14 is also provided with a self-closing pressure relief silicone sleeve 17. A hot water chamber for storing water is formed between the insulated outer tank 23 and the insulated inner tank 10. The self-closing pressure relief silicone sleeve 17 is arranged in the insulated outer tank 23 and connected to the hot water chamber. A heating device is provided in the hot water chamber. The core design is to set up three water pipe routes, including hot and cold water for washing, direct drinking hot water, and direct drinking cold water. It can also be interpreted as more ways of using water, which will not be elaborated or restricted here. A filtering device 3 is provided to reduce pollutants, improve the purity rate, and solve water problems in the kitchen or other scenarios. Generally speaking, after being filtered, the drinking water enters the cold drinking branch 6 and the hot drinking branch 7 respectively. The difference is that the water in the hot drinking branch 7 will also enter the thermal insulation inner liner 10, and there is heat exchange between the thermal insulation inner liner 10 and the thermal insulation outer liner 23 for heating, that is, the water in the hot water chamber indirectly heats the drinking water. The hot water chamber is also provided with a preheating liner 18 connected to the cold drinking branch 6. The body 1 also includes a cooling liner 19 arranged outside the thermal insulation outer liner 23. There is a heating pipe 20 between the preheating liner 18 and the cooling liner 19 for directly injecting hot water into the cooling liner, and a heater 21 is provided at the heating pipe 20. The cooling liner 19 is directly connected to the water tap. It is explained here that with the long-term use of the filter material, the filtering effect will be reduced. In order to ensure safe and reliable drinking, the cold drinking water is first preheated through the hot water chamber, or the preheating liner 18, and then drained to the heater 21 for boiling and disinfection, and cooled at the cooling liner 19 for direct drinking. When in use, the valve is opened normally, and the water in the preheating tank 18 is pressed into the cooling tank 19, and the cold water in the cooling tank 19 is naturally squeezed out or flows out. No further explanation or limitation is given here. The thermal insulation tank 10 is also provided with a hot direct drinking and cold boiled water opening pipe 22, which is a pipe connection form, mainly to explain that it can be drunk directly hot or boiled after the water is discharged, which is different from the cold direct drinking form, and no further explanation or limitation is given here.The insulated outer liner 23 encloses the insulated inner liner 10 and preheating liner 18. A second heating tube for super-boiling heating is located near the direct drinking hot water section of the faucet. The insulated outer liner 23 is a relatively large chamber that contains the other water bladders, maintaining a constant water temperature of approximately 90°C. Direct drinking cold water is heated to 90°C, then super-boiled to 100°C by heating tube 1, and then cooled in cooling liner 19. A second heating tube for super-boiling heating of the direct drinking hot water reaches the target temperature near the faucet.

[0016] After the washing water passes through the third solenoid valve 12, the cold water flows directly to the flow solenoid valve 16. The flow solenoid valve controls the cold water flow according to different water temperatures and injects the excess cold water into the hot water chamber inside the thermal insulation tank. The thermal insulation outer tank has a built-in hot drinking pipe. The water outlet of the thermal insulation outer tank is equipped with a self-closing pressure-relieving thermal insulation silicone sleeve. When the thermal insulation tank is pressurized, the hot water is squeezed out through the self-closing pressure-relieving silicone sleeve and mixed with the cold water from the flow solenoid valve to achieve the required water outlet temperature. It should be noted that the hot water in the hot water chamber is equivalent to continuously heating and accumulating to the full capacity before overflowing, thus achieving the effect of heating and pressurizing and then squeezing out.

[0017] The heating device is a PTC quartz tube or an electric heating tube, and the thermal insulation inner tank 10 is also provided with a self-closing pressure relief silicone sleeve 17 connected to the hot water chamber. PTC heater, also known as PTC heating element or PTC heater, is an electric heater that uses the characteristics of PTC (positive temperature coefficient) material to achieve automatic constant temperature and efficient heating. The main advantages of PTC heaters include: low thermal resistance, the thermal resistance of PTC heaters is relatively small, which means that they can transfer heat quickly and efficiently. High heat exchange efficiency, the heat exchange efficiency of PTC heaters is very high, which enables them to achieve effective heating with a smaller energy input. High safety, PTC heaters will not have a red surface like some types of heaters, which can avoid burns and other safety hazards. Energy saving, PTC heaters can save energy by intelligently adjusting the output power, especially when the air volume remains unchanged. As the ambient temperature rises, the power of the PTC heater will gradually decrease, thereby achieving energy saving. A PTC heater consists of a PTC ceramic heating element and an aluminum tube, and may also include other components such as a galvanized outer pressure plate, a stainless steel corrugated spring, a galvanized inner pressure plate, a single-layer aluminum heat sink, a PTC heating element, a double-layer aluminum heat sink, nickel-plated copper electrode terminals, and a polymer plastic sheath. These components work together to ensure the PTC heater provides stable heating. Similarly, electric heaters are mature products, differing in their use of alternative heating elements. A tubular heating element (also known as a heating tube) is an electrical component that converts electrical energy into heat. It features a metal tube (including stainless steel or copper) with a spiral heating alloy wire (nickel-chromium or iron-chromium alloy) uniformly distributed along the central axis of the tube. The interstices are filled with compacted magnesia sand, which has excellent insulating and thermal conductivity. The tube ends are sealed with silicone rubber. This metal-clad heating element can heat air, metal molds, and various liquids. Common heating tubes include finned heating tubes, Teflon heating tubes, and quartz heating tubes. Due to its low price, easy use, easy installation and no pollution, it is widely used in various heating occasions.

[0018] The self-closing pressure-relieving silicone sleeve 17 can be a self-closing silicone member with no gaps in the static state, so hot water or hot air will not leak. When the heat and pressure in the pipe are too high, the gap expands and opens, thereby significantly increasing the flow rate to release pressure and drain water. The self-closing pressure-relieving heat-insulating silicone sleeve can ensure that the heat-insulating outer liner 23 is in a heat-insulating and pressure-free state for a long time, effectively extending the service life of the heat-insulating outer liner. No excessive restrictions are made here. The filter device 3 is a single filter cartridge. This is only one embodiment. The pre-filter device 3 is suitable for families with water purification requirements.

[0019] The end of the water supply branch pipe 13 is located near the bottom of the hot water chamber, which facilitates the extraction of more stable hot water, that is, providing water with a relatively stable temperature without fluctuating between hot and cold. The body 1 also has a mounting platform, and the first solenoid valve 8, the second solenoid valve 9, the third solenoid valve 12, and the flow solenoid valve 16 are all fixed to the mounting platform via a mounting bracket, which facilitates centralized layout and structural optimization, thereby improving integration.

[0020] Example 2: Different from Example 1, Figure 5 As shown, the filter device 3 is a fine filter device 3 of a multi-filter cartridge, which has a more refined filtering box structure and can provide a purer water source. The filter material or layout here is implemented in various ways on the market, and there are no excessive restrictions here. This is mainly an explanation of the implementation of the filtering part, and is not limited to a single or simplified pre-filter design. At the same time, according to local water quality conditions, it can also be directly connected to the direct drinking pipeline, rather than necessarily passing through the filter device 3.

Therefore, they cannot be understood as limitations on the present invention. At the same time, the basic principles, main features and advantages of the present invention are shown and described above, which should be understood by technicians in this industry.
