The coil is electrified to generate magnetic eddy current to act on the heating pipe, so that the water flow flowing through the heating pipe can be heated immediately. Of course, in other embodiments, a combination of multiple tubes and coils or other configurations may be used, and are not limited.

The reservoir 30 may have a capacity of less than or equal to 10 liters, and may have a capacity of 1 liter, 2 liters, 3 liters, 4 liters, 5 liters, 6 liters, 7 liters, 8 liters, 9 liters, 10 liters, etc., in order to avoid excessive storage of cold water, which may result in poor heating per use. The water reservoir 30 may be cylindrical, rectangular parallelepiped, or square.
The inside of the second electromagnetic heating device 50 is provided with a water flow channel, and a water inlet and a water outlet are formed, the water inlet of the second electromagnetic heating device 50 is communicated with the water outlet of the water receiver 30, the water outlet of the second electromagnetic heating device 50 is communicated with the hot water outlet pipe 20, and the second electromagnetic heating device 50 realizes rapid heating to prepare hot water at a required temperature by generating water flow flowing through the inside of the electromagnetic heating device. The second electromagnetic heating device 50 is connected to the hot water in the water reservoir 30, and discharges the hot water to the hot water outlet pipe 20 after being heated for the second time, so as to be provided to the user.
In this embodiment, the second electromagnetic heating device 50 may be a pipe-line type fluid heating device, for example, the second electromagnetic heating device 50 includes a heating pipe and a coil, and the coil is wound on the heating pipe. The coil is electrified to generate a magnetic eddy current to act on the heating pipe to realize the instant heating of the water flow flowing through the heating pipe. Of course, in other embodiments, a combination of multiple tubes and coils or other configurations are also possible, and not limited.
The electric control device 60 is mainly used for supplying power to the first electromagnetic heating device 40 and supplying power to the second electromagnetic heating device 50. The electric control device 60 is also used for controlling the heating power of the first electromagnetic heating device 40 and the second electromagnetic heating device 50. That is, the electric control device 60 may include a power supply portion 61 and a controller 62, and the controller 62 is connected to the power supply portion 61. The first electromagnetic heating device 40 and the second electromagnetic heating device 50 are respectively electrically connected with a power supply part 61, and the power supply part 61 provides working power supply for the first electromagnetic heating device 40 and the second electromagnetic heating device 50 respectively. The controller 62 may control the magnitude of the power of the output of the power supply portion 61, and therefore, the controller 62 may adjust the heating power of the first electromagnetic heating device 40 or the second electromagnetic heating device 50, or adjust the heating power of the first electromagnetic heating device 40 and the second electromagnetic heating device 50.
It should be noted that the electronic control device 60 can selectively control one or both of the first electromagnetic heating device 40 and the second electromagnetic heating device 50 to start up according to the requirement, and further control the heating power of one or both of the first electromagnetic heating device 40 and the second electromagnetic heating device 50, which is for the purpose of saving the requirement of energy and avoiding reducing the service life of the water heater.
When a large amount of hot water is required, the first electromagnetic heating device 40 and the second electromagnetic heating device 50 may be controlled to operate simultaneously to increase the production amount of hot water. Wherein, the hot water heated by the first electromagnetic heating device 40 firstly enters the water storage device 30, is heated by the second electromagnetic heating device 50 for the second time, and is delivered to the hot water outlet pipe 20, and finally is delivered to the water consumption end of the user through the pipeline. Of course, if there is cold water in the water reservoir 30, the hot water heated by the first electromagnetic heating device 40 will be mixed with the cold water in the water reservoir 30 after entering the water reservoir 30, and then enter the second electromagnetic heating device 50 for heating. It can be understood that the normal temperature water is heated by the electromagnetic heating device, the heating is fast, and after the normal temperature water is heated by the first electromagnetic heating device 40 and the second electromagnetic heating device 50 twice, the temperature is higher, the heating amount is large, and a small amount of hot water can be mixed with more normal temperature cold water. In addition, the water heated by the second electromagnetic heating device 50 is discharged through the hot water outlet pipe 20, so that cold water in the water storage device 30 does not need to be discharged first, and the waste of water is reduced while hot water is discharged quickly.
When a small amount of hot water is required, only the first electromagnetic heating device 40 or the second electromagnetic heating device 50 may be controlled to operate to produce hot water. Because water can remain in the water receiver 30 and the pipeline after the water heater is used, when a small amount of hot water is needed, the second electromagnetic heating device 50 can be controlled to work preferentially, and the first electromagnetic heating device 40 does not work, so that cold water in the water receiver 30 does not need to be discharged first, and the waste of water is reduced while the hot water is discharged quickly.
It can be understood that, when the water heater is in operation, the electric control device 60 starts to control the first electromagnetic heating device 40 to work, or controls the second electromagnetic heating device 50 to work, or controls the first electromagnetic heating device 40 and the second electromagnetic heating device 50 to work simultaneously according to a user instruction or a preset instruction, hot water is produced by heating, and the water heater heats normal-temperature water by electromagnetism, is fast in heating, can meet the demand of instant and fast hot water use, solves the pain point of the traditional electric water heater needing to wait for a long time, and has the same convenience as a gas water heater in instant hot water use. In addition, after the normal temperature water is heated twice by the first electromagnetic heating device 40 and the second electromagnetic heating device 50, the temperature is higher, the heating amount is larger, a large amount of hot water can be supplied, and waiting and waste required by discharging cold water in the water storage device 30 can be reduced. In addition, through the storage effect of water receiver 30, avoided the water in-process suddenly to have a power failure or cut off the water, can't accomplish water demands such as bathing to satisfy a plurality of water ends of user and use hydrothermal demand in a large number. In addition, water and electricity isolation can be realized through electromagnetic heating, and the use is safer.
Therefore, the water heater has the advantages of being capable of being used immediately after being opened and the advantages of using clean energy in the traditional electric water heater, and is more environment-friendly and safer.
Further, the water heater of the present invention may be configured with a plurality of usage modes, for example, a bathing mode, and the electric control device 60 controls the first electromagnetic heating device 40 and the second electromagnetic heating device 50 to operate when receiving a bathing mode command, so as to heat water to a first preset temperature, so as to provide bathing water. The temperature of the bath water is generally in the range of 37-50 ℃, the first preset temperature can be the water temperature directly required by a user, or the temperature of the bath water is higher than the water temperature, and the bath water is mixed with cold water to obtain the water with the required temperature. For energy conservation reasons, the water may be heated to a temperature slightly above the water usage temperature, thus avoiding the use of less water and the reservoir 30 storing the high temperature water that is not used up to waste energy.
The electric control device 60 is configured to control the first electromagnetic heating device 40 and the second electromagnetic heating device 50 to operate when receiving a drinking water mode command, so as to heat water to a second preset temperature to provide drinking hot water. Drinking hot water is typically "boiled water" or "boiling water" heated to 100 degrees celsius or above to ensure that microorganisms and bacteria in the water are killed.
An energy-saving mode or a small water consumption mode can be configured, and the electric control device 60 is configured to control the second electromagnetic heating device 50 to heat the water to a preset target temperature or a temperature set by a user when receiving an energy-saving mode instruction or a small water consumption mode instruction, so as to directly provide hot water at a required temperature. It will be appreciated that the water is heated to or slightly above the water usage temperature due to the low water usage, so that the user can use it more or less, thus avoiding the waste of energy due to the low water usage and the water reservoir 30 storing high temperature water that is not used completely.
The water consumption mode can also be configured in a large amount of water consumption mode, namely when water consumption of a plurality of water consumption ends is detected, the first electromagnetic heating device 40 and the second electromagnetic heating device 50 are controlled to work at a preset power value to heat water to a fourth preset temperature, so that the water consumption ends can obtain hot water with higher temperature, and then water with target temperature is obtained by mixing a large amount of cold water, so that the total amount of the mixed cold water is more by providing hot water with higher temperature in unit time, and the requirement of large amount of hot water can be met. Wherein the preset power value may be a rated power value of the first electromagnetic heating device 40 and the second electromagnetic heating device 50.
If a plurality of water consumption ends are opened, the water consumption temperature can be determined by the water consumption end with the highest temperature, and if a user needs water at 60 ℃, and then another user takes a bath at the same time, and the needed hot water is 45 ℃, the hot water discharged by the water heater is greater than or equal to 60 ℃.
In an embodiment, the first electromagnetic heating device 40 includes a first tube 41 and a first coil 42, and the first coil 42 is electrically connected to the electric control device 60.
The first tube 41 has a water inlet and a water outlet, the water inlet of the first tube 41 is connected to the cold water inlet pipe 10, and the water outlet of the first tube 41 is connected to the water inlet of the water reservoir 30. The first coil 42 is wound around the first tube 41. The first coil 42 may be spirally wound from one end to the other end of the first tube 41 in order to be wound on the first tube 41.
