Problems solved by technology

For users with high water pressure, water dripping from the safety pressure relief valve often occurs, and the inner tank pressure detection cannot be automatically controlled;
[0003] At present, there are also many products based on the variable capacity heating technology of electric water heaters, but they all face the phenomenon that the inner tank pressure and the water inlet pressure are not balanced during the variable capacity operation process, resulting in uncontrollable water volume in the inner tank. Make up for this problem, but the control is very difficult, and the control is not reliable for different user environments

Abstract

The embodiment of the invention discloses an inner container parameter control device for an electric water heater. The electric water heater comprises an inner container, a heating assembly and a water inflow and outflow control unit, and inner container parameters include the inner container pressure value. The device comprises a microcontroller and a pressure control unit arranged outside the inner container. The microcontroller controls the water inflow and outflow control unit, and accordingly the electric water heater can work in different work modes. The work modes include the whole container heating mode, the half container heating mode and the variable volume mode. The pressure control unit detects the pressure value in the inner container in real time when the electric water heater is in different work modes, and the pressure value is fed back to the microcontroller in real time. The microcontroller controls the pressure control unit to act according to the pressure value, accordingly, the pressure difference between the inner container and the outside can be balanced or the pressure value needed for water inflow and outflow in the current work mode is achieved. Through the embodiment scheme, the electric water heater inner container pressure parameters are reliably and automatically detected, and reliable control over the electric water heater is achieved.

Description

technical field [0001] The embodiment of the present invention relates to the control technology of household electrical appliances, in particular to a device for controlling inner tank parameters of an electric water heater. Background technique [0002] At present, in order to detect the pressure of the inner tank of electric water heaters, most of them just install a safety pressure relief valve on the electric water heater. When the pressure of the inner tank reaches the threshold of the safety pressure relief valve, the internal structure of the safety pressure relief valve is turned on to release the pressure of the inner tank. pressure. For users with high water pressure, water dripping from the safety pressure relief valve often occurs, and the inner tank pressure detection cannot be automatically controlled; [0003] At present, there are also many products based on the variable capacity heating technology of electric water heaters, but they all face the unbalanced...
