Stepped instant water boiler

Abstract

The invention discloses a stepped instant water boiler. The stepped instant water boiler comprises a water tank, a stepped hot water storage tank, an instant heater and a water outlet tap, wherein a water inlet control valve is arranged at a water inlet of the water tank, and a water outlet of the water tank is connected with a water inlet of the stepped hot water storage tank through a pipeline;a water outlet of the stepped hot water storage tank is connected with a water inlet of the instant heater through a pipeline; and a water outlet of the instant heater is connected with a boiled wateroutlet control valve and a step-by-step heating control valve. The step-by-step heating mode comprises the steps that water in the stepped hot water storage tank is preheated by using the instant heater, and when the water is boiled, the preheated water in the hot water storage tank enters the instant heater so that the water yield of the boiled water can be increased. The advantages of a volumetric water boiler and an instant water boiler are combined ingeniously, the disadvantages are avoided, the energy consumption is reduced compared with the prior art, the condition of repeated boiling of water is eliminated, the high yield of the boiled water can be guaranteed, and the user experience is good.

Description

technical field [0001] The invention relates to a water boiling device, in particular to a step-by-step instant water boiler. Background technique [0002] At present, various drinking water heating devices such as water dispensers, water dispensers, direct drinking machines, and pipeline machines use heating systems, one is the traditional water tank volumetric water storage heating method; the other is step-by-step control volumetric water storage heating The third is the instant heating method. [0003] The volumetric water storage heating method needs to maintain the water temperature of the water tank in a boiling state for a long time, resulting in frequent heating, which is the so-called thousands of boiling water. First, the water quality is unhealthy; High-temperature and high-humidity water vapor enters the machine, causing corrosion of machine structural parts and a high failure rate of the electronic control system. [0004] The instant heating method is heated...

Problems solved by technology

[0003] The volumetric water storage heating method needs to maintain the water temperature of the water tank in a boiling state for a long time, resulting in frequent heating, which is the so-called thousands of boiling water. First, the water quality is unhealthy; High-temperature and high-humidity water vapor enters the machine, causing corrosion of machine structural parts and a high failure rate of the electronic control system

[0004] The instant heating method is heated once for drinking, which is healthy and energy-saving, but heating the water temperature directly from the ambient water temperature to the boiling state requires strong electric power support, which leads to insufficient wire capacity in many usage scenarios and cannot provide strong heating power. Currently, households and general offices The heating power commonly used in the place is limited to about 2000W, which leads to a small amount of boiling water per unit time, only about 350-400ml per minute of boiling water supply, the user experience is very poor, and the water output is even smaller in winter

[0005] In the actual use of water boiler products, volumetric water boilers have a large flow of boiling water per unit time, which is stable, but the water quality is not healthy enough and wastes electric energy. Instantaneous heating water boilers have high instantaneous electric power, and the water output is small in the case of low power usage. Problems such as poor user experience
