Multi-stage magnetic energy induction heating water heater based on single control

Abstract

The invention discloses a multi-stage magnetic energy induction heating water heater based on single control. The multi-stage magnetic energy induction heating water heater based on single control comprises a heat storage heating device, a temperature sensor, an electromagnetic heating body, a thermostatic valve and a Hall flow sensor which is arranged in a water outlet interface of the thermostatic valve, wherein a water inlet interface of the electromagnetic heating body communicates with a water outlet end of the heat storage heating device through the thermostatic valve; an electromagneticcoil panel and a heater matched with the electromagnetic coil panel in use are arranged on the bottom side surface of the heat storage heating device; the output end of an IGBT power module is electrically connected with the electromagnetic coil panel and the electromagnetic heating body through a single-pole double-throw switch type and a relay, respectively; a control circuit board which is electrically connected with the temperature sensor, the Hall flow sensor, the IGBT power module and the relay respectively is also arranged; and the conduction state of the relay is controlled accordingto the Hall flow sensor or / and the temperature sensor so as to select to connect the IGBT power module with the electromagnetic heating body or the electromagnetic coil panel. The multi-stage magneticenergy induction heating water heater based on single control is low in implementation cost and easy to implement.

Description

technical field [0001] The invention relates to a water heater, in particular to a multi-stage magnetic energy induction heating water heater based on single control. Background technique [0002] This section only provides background information related to the application to facilitate those skilled in the art to understand the application more thoroughly and accurately, and it is not necessarily the prior art. [0003] Traditional water storage water heaters are too bulky, especially large-capacity electric water heaters, which need to be turned on to start heating before use, and users have to wait for a long time. Although the air energy water heater is energy-saving, it has the disadvantages of high price, noise, troublesome installation, large volume and high maintenance cost. Then a phase-change energy storage water heater appeared. By pre-heating the phase-change material during the period of underestimation of electricity consumption, the heat is stored in the phas...

Problems solved by technology

[0004] Due to the fixed heat storage capacity of the existing phase-change water heaters, it is impossible to have both the heating time and the large water flow: if the phase-change water heater needs to be in a certain heating time, it is necessary to reduce the hot water supply per unit time. At the expense of reducing the amount of hot water flowing out in exchange for a longer heating duration; on the contrary, if the user needs to provide hot water with a large flow, the heating duration of the phase change water heater will inevitably be greatly shortened

If the phase-change water heater is used in conjunction with the existing instant water heater, and the instant water heater is used for secondary heating, the two are completely independent electrical appliances, and linkage work cannot be achieved, which is inconvenient for users.
