Abstract

A water heater, comprising a casing, a water inlet pipe, a heating chamber and a water outlet, the water inlet pipe and the heating chamber are located inside the casing, the water outlet extends to the outside of the casing, the heating chamber is located between the water inlet pipe and the water outlet; Heat exchanger, the cold and heat exchanger is located between the heating chamber and the water outlet; the cold and heat exchanger includes an inner pipe waterway and an outer pipe waterway, wherein the inner pipe waterway is in a serpentine shape, and the inner pipe waterway connects the heating chamber and the water outlet The water outlet and the outer pipe are connected to the water inlet pipe; compared with the existing technology, the boiling water in the water heater is heated to a boiling point of 100°C through the action of the pressure barrel, and boiled water with a boiling point of 100°C can be continuously produced; at the same time, the function of the cold and heat exchanger It can continuously provide warm boiled water at 50°C (±5°C) without mixing yin and yang water, and the internal water can be released before use to ensure that there is no overnight water; it can be used with bottled water or direct drinking water.

Description

technical field [0001] The invention belongs to the technical field of water dispensers, in particular to a water warmer. Background technique [0002] In kindergartens, since the immune system of kindergarten children is not yet fully developed, drinking water is convenient and has higher requirements. At the same time, when the kindergarten children are pouring water, the water temperature should not be too high to prevent the children from being scalded. Cool white water with a certain temperature is required. Because of the water temperature requirements, the traditional kindergarten water boilers are directly mixed with boiled water and tap water to reduce the temperature to a range suitable for drinking. This will produce yin and yang water, which will seriously damage the health of children. [0003] Due to the presence of copepods, Escherichia enterica, Rhizopus stoloniferus, Chaetomium ascospores, filamentous cyanobacteria Anabaena, Legionella, Naegleria fowleri, ...

Problems solved by technology

[0004] However, according to the current industry standard of SB / T10460-2008 commercial electric water boilers - "the water outlet temperature of the water boiler should be ≥ 92 ℃", so generally the existing water boilers will not heat the water boiler to the boiling point of 100 ℃, and because the water When heated to the boiling point, a large amount of steam is generated. If the steam is not released in time, it will cause overpressure in the water storage tank and bring a series of hidden dangers. Therefore, no water storage type water boiler can boil water to the boiling point of 100°C.

[0005] In the prior art, the water boilers currently on the market mainly include water dispensers, traditional fully automatic water dispensers, step-by-step water dispensers, and warm and hot water dispensers; the bottled water dispensers for kindergartens can only be heated to warm water Unable to effectively kill bacteria; traditional automatic water boilers have a low utilization rate of boiling water, and the mixture of boiled water and raw water is serious. In actual use, the outlet water temperature is about 85 degrees Celsius, and it cannot be guaranteed to be heated to 100 degrees Celsius; the step-by-step water boiler outlet water temperature is 92 degrees Celsius It can’t be heated to the boiling point of 100 degrees Celsius when it is set at 95 degrees Celsius; the inner capacity of the dual-purpose water boiler is 18-30 liters, because the inner container and the entire water system are in a fully enclosed structure, although there are double pressure relief valve protection devices , but the action state of the pressure relief valve is that the pressure of the inner tank reaches 500kpa, which is the corresponding pressure when boiling water is heated to 150 degrees Celsius. Warm water, the amount of water is also more effective
