Description

DESCRIPTION FOR KITCHEN APPLIANCES CONSTRUCTION OF CAPACITIVE LIQUID LEVEL DETECTION Bulus is one of the most important companies in its body, especially automatic coffee and tea machines. It is concerned with the detection of liquid in kitchen utensils containing at least one liquid reservoir.

The invention aims to reduce the amount of liquid in kitchenware with at least one liquid reservoir. observation, quantification, and the measured amount Level detection that warns when it reaches the level or can add liquid regarding methods.

In particular, the invention relates to the use of liquid in utensils comprising at least one liquid reservoir. It is related to the detection of the device with the capacitive method.

The feature of our invention; printed circuit board of liquid detection in kitchen utensils and by providing ease of assembly and production in a low-cost way with the capacitive method. is characterized by the provision of measurement.

State of the Art Today, with the advancement of technology, many kitchen tools and utensils are used. development has been made, and the most used automatic tea, coffee and so on. this are heaters.

These kitchen utensils generally have at least one liquid reservoir. and this reservoir is filled with water. Only the amount of water filled can be determined by eye only. manual water filling at the discretion of the user as it is visible is being done.

When it is desired to fill the water in the liquid reservoir automatically, the liquid controlling the reservoir with at least one sensor and determining the amount of liquid required.

Liquid detection is generally with a chandelier, magnetic or optical and ultrasonic. systems, and the biggest disadvantage of these methods is that they are quite costly. and the production stages are difficult.

Another method is weight sensors placed under the cabinet where the liquid is located. through which the amount of liquid can be monitored. The said sensors, together with the liquid When the weight falls below a certain amount, it gives a warning. only about weight such sensors in measurements, due to the weight and usage errors on them. can deteriorate very quickly.

Today, some improvements have been made regarding the above methods, some are like this; It is related to the measurement system of the liquid (2) level outside the tank (1) with sound waves. system warehouse By sending ultrasonic sound waves from the outer bottom surface (9) into the tank (1), these waves are the liquid (2) to hit the surface and return, this returning wave is received and the wave is sent and The method of finding the distance (liquid level) by processing the time between taking uses. It is described as ”.

Brief Description of the Invention The present invention fulfills the above-mentioned requirements, has all the disadvantages capacitive liquid for kitchen utensils, which eliminates It relates to a system for level detection.

Capacitive sensors are used to detect objects and substances approaching the capacitor's electric field. They are sensing elements that detect the capacity change it creates. Working principle, capacitance due to the difference in the dielectric coefficient of the material in front of it It is based on measuring and making sense of the change. This is the capacitive sensor. Its feature is used in detecting the level changes of the liquids in the container. expected to be used.

Capacitive liquid level detection for kitchenware, which is the subject of the invention the main purpose of its structuring; capacitive sensor placed outside the liquid reservoir, Detection of the liquid in the chamber and the liquid falling below a certain level signal generation, sound, or the desired element. its realization.

Another purpose of the invention; production according to equivalent measuring systems and structures and its cost in terms of assembly is at a minimum level and it has an easy structure.

The structural and characteristic features of the invention and all its advantages are given below. Thanks to the figures and the detailed explanation with references to these figures. will be more clearly understood, and therefore the evaluation will be based on these forms and should be made taking into account the detailed explanation.

There are also some elements prepared to provide a better understanding of the invention. It is also used in different ways to ensure the integrity of meaning in sentences. it could be. The elements used in different expressions are actually the same numbered related represents the element.

The invention is based on the pressure of liquid detection in liquid chambers (2) in kitchen utensils. circuit board (1) and accordingly the construction of the capacitive method.

For this, at least one card slot (2.1) on the outer wall of the liquid reservoir (2) and at the bottom of the liquid chamber (2), just below the card slot (2.1). The reference space (2.2) that it does not touch is created.

Capacitive plates (1.1) and active passive electronic circuit elements The capacitive level measurement circuit board (1) with (1.2) is in the liquid reservoir (2). It is positioned in the created card slot (2.1).

The capacitive level measurement circuit board (1), which is located in the liquid reservoir (2), while measuring the presence or amount of liquid in the chamber (2) measurement from the reference gap (2.2) formed at the bottom of the liquid chamber (2) first It adjusts the reference and liquids the liquid by means of the capacitive plates (1.1) in it. The liquid level in the chamber (2) is due to the difference in the dielectric coefficient. It detects it based on the capacity change that occurs.

Thus, the capacitive level measurement circuit board (1) performs predetermined operation. When the liquid runs out or reaches a certain limit according to the steps, the desired action is taken. and can instantly determine the amount of liquid.
