A probe-based water level detection method, device, and steam oven

By controlling the emptying of residual water in the water tank during steam mode startup and determining the judgment value based on the pulse value triggered by the probe to detect the water level, the water level detection is adjusted in real time, thus solving the problem of inaccurate water level detection in steam ovens and ensuring reliable operation and user experience of steam ovens.

AI Technical Summary

Technical Problem

Existing steam ovens have inaccurate water level detection in steam mode, which affects the normal use of the steam oven. The inaccurate water level detection in the water tank of the steam oven reduces the user experience.

Method used

When the steam mode is started, the water volume in the test tank is controlled, and the water pump is controlled to add water to the test tank to make the water volume reach the maximum water level. The first pulse value triggered when the probe detects the water level is obtained, and the judgment value is determined based on the first pulse value. The evaporator is controlled to start heating, and the real-time pulse value is obtained in real time during the heating process to determine that the water level is low.

Benefits of technology

It enables precise water level detection during the evaporator heating process, avoiding misjudgments, ensuring the reliable operation of the steam oven, and improving the user experience.

Abstract

This invention discloses a probe-based water level detection method, device, and steam oven, comprising: draining residual water from the water tank to be tested when the steam mode is activated; controlling a water pump to add water to the water tank to reach the maximum water level; acquiring the first pulse value generated when the probe detects the water level, and determining a judgment value based on the first pulse value; controlling the evaporator to start heating, and acquiring the real-time pulse value generated when the probe detects the water level during the evaporator heating process; determining the water level of the water tank to be tested as low when the real-time pulse value is less than the judgment value. This invention provides a technical solution to adjust the water level judgment value in real time according to the working status of the steam oven, thereby reducing the misjudgment rate in the water level judgment process, improving the accuracy of water level detection, and ultimately enhancing the user experience.
