Water boiler with two heating systems

Abstract

A water boiler of a dual-heating system, comprising a housing (1), a first level heating system and a second level heating system that are arranged in the housing (1), an integral foam layer (4) filled between the housing (1) and the first level heating system and the second-level heating system. The first level heating system comprises a first level heating water tank (5), a first level electric heating pipe (7), a first level temperature sensor (6), a water replenishment pipe (8), and a water replenishment solenoid valve (9). The second level heating system comprises a second level heating water tank (2), a second level electric heating pipe (11), a second level temperature sensor (13), and a water level switch (3). The second level heating water tank (2) is connected at the lower part thereof to a drinking water faucet (12). The top part of the first level heating water tank (5) is in communication with the second level heating water tank (2) via a pipe. The water level switch (3) is electrically connected to the water replenishment solenoid valve (9). This, by preventing unboiled water from mixing with boiled water, improves drinking water hygiene, allows for increased amount of continuous water output, provides a compact structure, great thermal insulation effects, and increased energy conservation.

Description

technical field [0001] The invention relates to the field of electric water boilers, in particular to a water boiler with dual heating systems. Background technique [0002] Traditional water boilers generally only have one water tank. Raw water enters the water tank and is heated to boil. When the water level is lower than the warning water level, it will replenish water. If someone uses water at this time, it will cause raw water and cooked water to mix, which is not suitable for drinking water health. Requirements; At the same time, if it is necessary to meet the centralized water consumption of many people, the power of the water boiler and the volume of the water tank must be increased, which increases the cost of the user. [0003] The traditional water boiler has poor heat preservation performance. For example, when the water is not used for a long time at night, the electric heating is frequently started and stopped, which does not meet the energy-saving requirements...
