Non-contact water kettle water level electronic detection and control method

Abstract

The invention discloses a non-contact water kettle water level electronic detection and control method. In the method, a rocker arm inlet valve which is communicated with a water pipe is involved; an outlet of the rocker arm inlet valve is connected with a water inlet of an electrically operated valve; a water outlet of the electrically operated valve is connected with an outlet pipe; the water inlet of the electrically operated valve is also provided with a thin water flow pipeline which has a longer size and of which a pipe wall is made of an insulation material; a water outlet of the thin water flow pipeline is provided with a resistance measuring point; both the water outlet of the thin water flow pipeline and a water outlet of the outlet pipe are higher than an upper opening of the water kettle; the electrically operated valve is electrically connected with a control circuit; and the control circuit also comprises a set of delay circuits. The method is characterized in that: the opening and closing signals of the electrically operated valve are from resistance variables from the water outlet of the thin water flow pipeline to a thin water flow column on the water surface of the water kettle. The water kettle water level electronic detection and control method is low in cost, not only can meet the requirement of chefs on using water, washing spoons and cooling a kitchen surface at any time, but also can ensure that the water kettle is convenient to take out and wash.

Description

technical field [0001] The invention belongs to the field of water saving, in particular to a water saving method for hotel kitchen supplies, especially a non-contact electronic detection and control method for the water level of a kettle. Background technique [0002] Hotels, restaurants, canteens and other catering industries use a cooking water pot (hereinafter referred to as the water pot). Some stoves have a single function requirement for this kind of water pot. It is required to have the following three functions: 1. It can meet the amount of water required for scooping water at any time, so as to add water to cooking soup and wash the cooking pot, that is, the water level needs to be full at ordinary times; 2. The frying spoon after cooking is often cleaned in the water pot , Therefore, when adding water, there must be a certain amount of water overflow, which is conducive to taking away the residue after cleaning the frying spoon; 3. Usually, the water pot needs a s...

Problems solved by technology

Because the chefs are very busy at work, they have no time to adjust the different water volumes required by the above three functions at any time, so at present, only by keeping the water pot with a large amount of water overflowing during the entire cooking period can the above three functions be taken into account. need

In fact, most of the time in the cooking process, only a small amount of water is needed to cool the stove surface, so a lot of water used in the water pot of the stove is wasted in vain. Now the catering industry is very prosperous, and there are many restaurants in cities and towns. Resources are very scarce, therefore, it is a very meaningful thing if the amount of water wasted by the stove water pot can be saved

Before the inventor invented a purely mechanical method for detecting and controlling the water level of the water pot, which can realize the above functions, but in the purely mechanical method for detecting and controlling the water outlet of the small water beam must extend into the water pot. It is troublesome to remove the device

At present, most of the electronic liquid level detection in commonly used technologies adopts contact methods, such as immersion electrodes, contact control, etc., and a small part uses non-contact methods, such as ultrasonic detection, laser reflection detection, etc. These contact detection methods are not suitable. Used on water pots, because there are obstacles in the water pots that will affect scooping water, and these non-contact detection methods are costly
