TR DESCRIPTION AN INDUCTIVE HEATER OF THE INTRA-FLOW TYPE This invention relates to an inductive heater of the through-flow type, suitable for use in washers and water heaters such as dishwashers or washing machines. Hot water and/or steam production in washers and water heating devices such as dishwashers and washing machines is generally carried out with resistive heaters, but resistive heaters cause significant heat losses. It is thought that using an inductive heater instead of a resistive heater minimizes these heat losses. For example, analyzes performed on a dishwasher show that when a resistive heater is used, the heat loss spread to the bottom of the dishwasher is considerably higher than when using an inductive heater. Since it will provide more efficient heating, the use of inductive heaters instead of resistive heaters in washers, heating installations where water heating is needed, and other water heating devices can be effective in reducing energy consumption values, which is one of the most important needs of today. It is envisaged that a flow-through or continuous flow type inductive heater, designed specifically for heating flowing water instead of water collected in a reservoir in washers, can significantly reduce energy consumption. In order for a through-flow type inductive heater to be suitable for use in such washers and water heaters, it must be designed to take up as much space as a conventional resistive heater and provide heating of flowing water and/or steam production by inductive transfer of high-density energy confined to a small volume. If the heat transfer conditions to the flowing water in the inductive heater are not improved, the dimensions of the inductive heater must be increased in order to provide the desired temperature level, and it is not intended for use in washers such as dishwashers, washing machines, and water heating devices as it will take up too much space. A washer, such as a dishwasher and a washing machine, is described in which it is used. The purpose of this invention is to realize an internal flow type inductive heater, suitable for use in washers and water heaters such as dishwashers or washing machines, whose volume is reduced and heating efficiency is increased by improving heat transfer conditions. The inductive heater developed to achieve the purpose of this invention is suitable for use in washers such as dishwashers, washing machines, heating installations and various water heating devices, which have a transmission line that allows hot water or steam to be sent to the items to be washed-sterilized, and is internally designed to transfer heat to the flowing water. It is of flow type or also known as continuous flow type. The inductive heater of the invention is produced from magnetic material, connected to the transmission line, has a non-magnetic and heat-insulating feature, has a cylindrical body through which water passes, and an induction coil wrapped around the body, placed concentrically within the body, and has a hollow cylindrical structure. It contains a heating element, preferably in the form of a cylindrical-section pipe, which has a flow channel passing through the middle in the direction of the water flow, and provides heating of the water flowing through the body by producing heat with the magnetic energy emitted from the induction coil. In an embodiment of the invention, the outer diameter of the heating element is smaller than the inner diameter of the body and there is a gap between the outer surface of the heating element and the inner surface of the body. In this application, the water flowing through the inductive heater passes through both the flow channel in the middle of the heating element and the gap surrounding the heating element, and the heating element transfers heat to the water flowing inside and outside. In another embodiment of the invention, the inner diameter of the body and the outer diameter of the heating element are almost equal, the heating element is placed inside the body without any gaps, and the water passes only through the flow channel in the middle of the heating element. In another embodiment of the invention, the heating element consists of cylindrical helical windings placed inside the body and the flow channel is surrounded by the windings. In another embodiment of the invention, the heating element is placed inside the body without any gaps. In another embodiment of the invention, the heating element has a serrated structure to increase the contact surface with the water flowing inside and/or outside it, and has protrusions extending in the direction of the water flow on its inner surface and/or outer surface surrounding the flow channel. Inductive heaters are used to heat washing water and/or to produce steam for sterilization purposes in washers such as dishwashers or washing machines, in heating installations at homes and workplaces, and in water heaters, depending on the amount of current provided by the power unit, by improving the heat transfer conditions in a narrow volume and providing efficient use. Heating is provided and energy savings are achieved. The inductive heater built to achieve the purpose of this invention is shown in the attached figures, and from these figures; Figure 1 - is the schematic view of an inductive heater. Figure 2 - is a cross-sectional view of an inductive heater included in the preferred application of the invention. Figure 3 - is the perspective view of the inductive heater in Figure 2. Figure 4 - is the perspective view of an inductive heater containing a helical structure heating element.

A cylindrical body (2) or sleeve with a cylindrical structure, produced from a non-magnetic and thermally insulating material such as glass or polymer, through which water passes to be heated or to produce steam. It contains an induction coil (4) which is wound and energized by a power unit (3). The inductive heater (l) of the invention is - placed concentrically within the body (2), - has a hollow cylindrical structure, - is produced from magnetic material, especially ferromagnetic metal such as iron, - is surrounded by a cylindrical inner wall that directly contacts the water, It has a flow channel (5) passing through the middle in the direction of the flow, and contains a heating element (6) that provides heating of the water flowing through the flow channel (5) by producing heat with the magnetic energy emitted from the induction coil (4) wrapped around the body (2) (Figure 1). . Inductive heater (1) is suitable for use in washers such as dishwashers (12) and washing machines (22), and provides heating of the fluid, namely washing water, or production of steam by inductive transfer of high-density energy confined to a small volume. The inductive heater (l) has a structure that ensures that the energy transferred to the water, and therefore the heat, is trapped in the said small volume. The inductive heater (1) contains a body (2) around which the induction coil (4) to which current is applied by the power unit (3) is wound. The body (2) is produced from a non-magnetic and heat-insulating material such as silica-glass or polymer. The heating element (6) heats the water flowing inside the body (2) by producing heat with the magnetic energy emitted from the induction coil (4). The heating element (6) located in the inductive heater (1) of the invention has a hollow cylindrical structure and is placed concentrically within the body (2). The body (2), which has a thermal insulating feature, prevents the heat produced by the heating element (6) from spreading to the environment, overheating of the induction coil (4) and thermal losses that may occur due to heating. The heating element (6) contains a flow channel (5) passing through its middle in the direction of the water flow, thus increasing the contact area of the heating element (6) with water. In the inductive heater (1), heat losses are prevented by providing an evenly distributed, effective and efficient heating.
