ptc heater control system

Abstract

The invention discloses a PTC heater control system, which includes a power supply, a switching power supply, a control module, a drive module, a water pump and a heater containing several groups of PTC heating elements. The power supply is connected to the switching power supply, and the switching power supply is connected to the control module and the The drive modules are connected, and the water pump and several groups of PTC heating elements connected in parallel are respectively connected to both ends of the power supply. The control module and the drive module can transmit data to each other. The drive module can control the water pump to be turned on and off, and the drive module can control several groups of PTC heating elements. The elements are turned on, staggered and turned off in turn, and work alternately. There are several temperature sensors in the heating chamber of the heater. The temperature sensors are connected to the control module, and the temperature sensors can transmit data to the control module. Multiple advantages such as service life and safety, energy saving, etc.

Description

technical field [0001] The invention relates to a control system, in particular to a PTC heater control system. Background technique [0002] PTC heaters containing PTC heating elements have been gradually applied in many electrical products, such as electric water heaters, household massage and leisure pools, heaters, footbaths, Yuba, etc. However, at the moment of starting the PTC heating element, especially the moment when multiple sets of PTC heating elements are starting at the same time, a large inrush current will be generated, which is far beyond the normal working current, and has a great impact on the service life of the electrical appliance. , especially for high-power electrical products. The impact of the inrush current of PTC heating elements on the life of electrical appliances has not been paid attention to and solved by manufacturers at present. It is urgent to solve the problem of inrush current of PTC heating elements so that PTC heating elements can be b...

AI Technical Summary

Problems solved by technology

However, at the moment of starting the PTC heating element, especially the moment when multiple sets of PTC heating elements are starting at the same time, a large inrush current will be generated, which is far beyond the normal working current, and has a great impact on the service life of the electrical appliance. , the impact on high-power electrical products is particularly obvious

The impact current of the PTC heating element on the life of the electrical appliance has not been paid attention to and solved by the manufacturer at present. It is urgent to solve the problem of the impact current of the PTC heating element so that the PTC heating element can be better used.
