Description

PREVENTION OF LIMESCALE FORMATION WITH ULTRASONIC ENERGY AND

APPLICATION TO IRONING SYSTEMS

Technical Field

The invention relates to the prevention of the formation of limescale sediment layer at all times which leads to large financial losses, breakdowns, injuries, particularly in the case of household and steamed irons in which the water-heater pair is present.

More particularly, the invention relates to prevention of limescale formation and sedimentation which causes large material losses, defects and injuries on particularly home irons and iron with steam boilers, where the water-heater pair is present, by application of ultrasonic (supersonic) energy on the iron base. Background of The Invention

In today's industrial and household type steam irons, even have different models and systems, work by producing steam with the relation of water and heater which is originally composed of resistance and thermostat. The electric energy is converted to heat energy by the resistance and the temperature is adjusted by the thermostat. The steam is generated by the heat and water interaction obtained after the tank or the boiler, which are placed internally or externally to the iron, is filled with water. The water filled in the tank or the boiler is steamed by dropping a certain level on the base of the heated iron, making it easy to do the ironing.

In order to get the desired steam from the bottom of the iron, the ducts are formed in the inner parts and the steam output from the bottom of the iron is obtained as desired. Irons that work in the range of temperatures between 180 ° C-250 ° C, create the perfect environment for limescale formation and limescale accumulation with its heat, water vapor and intricate walls / paries build-up in the labyrinth form of aluminum castings. Limescale is caused by the calcium solution in the water. It can form as a layer on surfaces where water or vapor comes in contact. When limescale formation is not prevented or eliminated, it inhibits energy transfer, causing blockages and disruption of ducts and the like, leading to cost, safety and environmental problems.

In a study for limescale formation in the irons, it was seen that a 2 mm limescale layer cause 35% energy loss. This means that the lifetime of the device is reduced by 50%. It also creates difficulties in use and performance deficiencies. It also creates handling difficulties and performance degradation. This leads to huge economic losses, safety problems, customer dissatisfaction and increased technical service and breakdown costs for the iron manufacturers. Currently, various chemicals can be used with the aim of preventing scale formation. Various chemicals can be used with the aim of preventing scale formation in the present. However, the desired result could not be obtained.

In addition, applications such as the use of soft water or the use of water which is treated through various treatment processes can not be completely prevent limescale formation. At the same time, it brings along troublesome and unwanted additional work procedures for the user. In the existing new systems, especially irons with steam boilers, additional mechanisms and devices and anti-scale tablets are used, lime formed is reported by warning systems and additional steps are carried out to remove the limescale formed in certain periods of time. These systems are accompanied by additional costs and implementation procedures, which can create adverse effects for users and manufacturers.

As a result, the limescale formation problem encountered especially in the irons has not been completely solved with the approaches of the previous technical arts, and it has become necessary to make a technological improvement due to the limescale formation problem causing great energy losses, safety and environmental problems. At this point, the present invention has shown that, unlike all prior art approaches, provides a solution for the use of ultrasonic energy, which is used in many different areas of the industry, on the base of the iron, preventing limescale instantaneously and without additional procedures from being applied.

Summary of The Invention

The present invention is related to an instantaneous limescale prevention system for irons during usage which meets the above-mentioned requirements, removes all disadvantages and adds some additional advantages.

From the known state of the art, the object of the invention is to prevent instantaneous limescale formation in steam irons during usage. From the known state of the art, another goal of the invention is to put out the most efficient method to be applied for elimination limescale formation or bringing it to a minimum level.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In contrast to the methods used in all known applications of the prior art, the inventive system has been shown to eliminate instantaneous limescale formation or reduce it to a minimum level by the use of ultrasonic energy at the base of the iron (1 ), with the acoustic base (10) having equal frequency of vibration at each point, insulation plate(20) which is connected to acoustic base (10), provides the necessary heat insulation and transmitting the vibration frequency generated by the vibration source (30) to the acoustic base (10) without distorting the vibration, the control card forming the electrical signals, vibration source (30) which converts electrical signals, which come from said control card, to vibration frequency.

As a result of the work done, it was seen that ultrasonic vibration energy used in many different areas of the industry is the most suitable technique for providing the prevention of limescale in the steam irons(1 ) at the same time without any additional application or apparatus. Ultrasonic vibration energy has a reducing effect on the frictional force of objects with each other.

In other words, it reduces the cohering / adhesion effect. In addition, the "cavitation" effect allows the breakdown of lime molecules.

These effects of ultrasonic vibration energy will not diminish the quality of the end- effect steam over time, no limescale formation will occur, and high ironing comfort will be maintained for a long time. By means of the inventive system ultrasonic energy has been used to remove the limescale formed on the iron (1 ).

The present invention relates to a system in which includes: the acoustic base (10), the vibration source (30), the insulation plate (20) providing heat insulation between said acoustic base (10) and the vibration source (30) and also transmitting the vibration frequency to the acoustic base (10) without distortion and control card which ensures the operation of vibration source (30) at the desired frequency and power.

The acoustic base (10) is mounted together with the acoustic base cover (10.1 ) and other parts on the lower part of the upper iron body (40) as shown in Figure 1 . The vibration source (30) is connected to the control card located inside the iron upper body (40) and the vibration source (30) is positioned at the upper portion of the acoustic base (10) by being contacted with the insulation plate (20).

The control card of the present invention generates electrical signals necessary for the vibration source (30). The control card also senses the temperature of the vibration source (30), produces the electrical signals necessary for the production of the vibration frequency and sends them to the vibration source (30).

The control board instantaneously senses the temperature of the vibration source (30) and transmits the electrical signals necessary for the production of the vibration frequency to the vibration source (30) in the frequency range corresponding to the sensed temperature value.

The vibration source (30) converts the electrical signals ,which are sent by the control board corresponding to the desired frequency range, to the vibration frequency and transmit them through the insulation plate (20) and / or directly to the acoustic base (10). The insulation plate (20) mainly serves to protect the heat balance of the vibration source (30) and to minimize the damage to the vibration source (30) of the high temperature effects occurring at the base of the iron (1 ).

Insulation plate (20) is a component that intercepts the heat of the vibration source (30), provides insulation and at the same time transmits the vibration frequency without distortion. The acoustic base (10) is the basic part of the system. In order for the acoustic base (10) to be able to deliver the desired result, the vibration frequency transmitted from the vibration source (30) is provided to spread the acoustic base 10 uniformly at each point.

For this purpose, the acoustic base (10) is inherently obtained for each model, depending on the design model and the scale. What is important in the design and implementation of the acoustic base (10) is to ensure that the transmitted vibration is homogeneous at every point. For this purpose, the design is analyzed in a computerized manner in order to make the vibration homogeneous at all points of the acoustic base (10), and it is revised according to the analysis results until the optimum result is obtained.

In the system of the invention, the control card forms electrical signals, which are transmitted instantaneously and continuously to the vibration source (30). The vibration source (30) transmits the incoming electrical signals to vibration frequencies (ultrasonic sound wave) and transmits to the acoustic base (10) of the iron(1 ) via the insulation plate (20). Thanks to the transmitted vibration frequency, every part of the acoustic base (10) has ultrasonic vibration in the appropriate frequency range.

The "calcite" structure in the droplets of water drop on the acoustic base (10) to obtain steam is transformed into an "argonite" structure by virtue of the applied ultrasonic vibration and prevent from being formed in the ironing base.
