Description
AN INDUCTION COOKERFIELD OF THE INVENTIONThe present invention relates in general to induction cooking devices. In particular, the present invention relates to programmed induction cooking devices adapted for the requirements of Jewish commandments.BACKGROUNDInduction cooking is well known in the art. Induction technology works by creating a magnetic field that passes through, e.g., magnetic cookware (iron or steel), generating heat. Such induction technology applies an oscillating current to an electromagnet to produce an oscillating magnetic field. This magnetic field passes through the magnetic cookware, which generates heat in the cookware itself instead of the surface of a cooktop unit. Recently, induction cooking ranges have been developed for use in the home. Conventional counter-top induction cooktops have been developed that use this induction technology, but often present limited or rigid sets of features. The conventional induction cooking ranges are limited in their usefulness because they are often limited in functionality.The induction cooking device is built from a top surface, usually glass or ceramic. Under the surface there is an electric coil that receives voltage feed from a generator and a controller with a display that turns the generator on and off. The system receives power from a nearby power source. Using the controller, a user turns on the induction cooking device and set the heating intensity of the induction cooking device. When the power is interrupted, according to the induction cooking device's default, the device turns off completely.The induction cooking device is usually made of a material with an iron bottom (hereafter ferromagnetic vessel), which causes interaction between coil and a cooking vessel when the user places the cooking vessel on the surface above the coil. The interaction causes the coil to send out magnetic waves. The electromagnetic field creates an electric current that causes the cooking vessel to heat up. The induction cooking devices have advantages such as heating efficiency against energy consumption, cooking speed and safety in using the device.Various countertop ovens exist, including, e.g., microwave ovens. Although, conventional counter-top ovens heat food, they often do so by more conventional microwave, or infrared heating methods.Furthermore, according to the precepts of Jewish law, on Shabbat and holidays, interaction between an action performed by a believing person and an electrical device that causes a change in the current consumption of the electrical device is prohibited. Both the increase in the consumption of the electric current and the cessation of the consumption of the electric current, which is caused by a person's action during the Shabbat and the holiday, are prohibited.In the present situation, Jews families use a "Shabbat plate" on Saturdays and holidays to preserve the heat of cooked food. The grill only works at a preset temperature. A Shabbat hotplate is an electric stove that contains a heating element with a fixed and unchangeable heat intensity, intended mainly for preserving the heat of Shabbat foods until they are served at the Shabbat or holiday meal. In the situation that exists today, the food pots are not in refrigerators, but are placed for days on the Shabbat plate at a temperature that exposes the users to microbial dangers.Therefore, considering the foregoing discussion, there remains a need for an improved induction-based cooking device which is specially adapted to the requirements of Jewish Commandments (Halacha). It is an object of the present invention to address at least one of the above problems, or another problem associated with the prior art.SUMMARY OF THE INVENTIONThe following explanation describes an induction cooking device that meets the requirements of the religious Jewish Commandments.According to a first aspect of the present invention, there is provided an induction cooking device adapted to the requirements of Jewish commandments; the induction cooking device comprises: a surface (2); a copper coil (3); a generator (4); a dedicated controller (8); a main controller (5); an initialization component (10); and an adapter (11); wherein the generator (4) is configured to receive a command from the dedicated controller (8) to provide electric current to the copper coil (3) during a certain time frame that is programmed in the dedicated controller (8); wherein the copper coil (3) is adapted to create magnetic induction as a result of receiving the electric current from the generator (4); wherein the adapter (11) comprises a layer of ironor an alloy that includes iron placed over the surface (2) and is designed to receive the magnetic induction from the copper coil (3) and heat up as a result of the magnetic induction, and thereby enables heating or cooking of food that is inside a cooking vessel placed on the adapter (11) in the certain time frame without placement or removal of the cooking vessel causing a change in the electric current; and wherein the initialization component (10) is adapted to check if the dedicated controller (8) is on "Shabat" state when supply of electric current to the induction cooking device is restored, and to operate the dedicated controller (8); wherein the dedicated controller (8) is adapted to resume operation of the induction cooking device to the same state as the induction cooking device operated when supply of electric current was stopped, according to an operating plan of the dedicated controller (8).According to the precepts of Jewish law, on Shabbat and holidays, interaction between an action performed by a believing person and an electrical device that causes a change in the current consumption of the electrical device is prohibited. Both the increase in the consumption of the electric current and the cessation of the consumption of the electric current, which is caused by a person's action during the Shabbat and the holiday, are prohibited.Currently Shabbat hotplate is used in Jewish household to keep the food heated. The Shabbat plate is a hotplate, which is an electric stove that contains a heating element with a fixed and unchangeable heat intensity and is intended mainly for preserving the heat of Shabbat foods until they are served at the Shabbat or holiday meal.The use of an induction type cooking device is more efficient and economical than the use of a Shabbat plate. In the induction type cooking and heating devices that exist in the market today, when a user wants to cook, the user must turn on the device and set the cooking power, as well as place the pot on the device. Placing a pot or taking it down when the device is operating causes a change in the flow of electricity in the coil, so this operation is not possible on Shabbat or a holiday according to the laws of Jewish Commandments.Aim of the present invention is to allow the use of an induction type device on Shabbat and holidays according to the laws of Jewish Commandments.Another aim of the present invention is to enable the heating and cooking of the cookware placed on the induction device without causing a change in the electric current when the cookware is placed or when it is lifted from the cooking surface.The present invention provides a technical solution to the problems present in the prior art by using of an adapter which is placed on the induction surface that includes a layer of iron or an alloy that includes iron and a copper or aluminum plate on top of it. The iron layer regularly activates the induction coil, causing the coil to supply electricity at a constant voltage, regardless of placing or lifting cookware. In this way, placing or lifting the cooking utensils on the adapter does not fundamentally change the electricity consumption and thus allows the heating of food on Shabbat and holidays according to the laws of Jewish Halacha. Also, a copper or aluminum plate may be used to dissipate heat and increase the consumer's usable surface.Furthermore, the adapter placed on the induction surface that includes a layer of iron or an alloy that includes iron without a copper or aluminum plate that allows cooking (and not just heating) so that placing or lifting a pot on the adapter does not fundamentally change the electricity consumption, and thus allows cooking on holidays according to the laws of Jewish Halacha. (According to the laws of Jewish Halacha, a Jewish user can cook food on the holiday, while on Shabbat user can only heat the food, and all this on the condition that user do not cause a change in the electric current of the heating device).Using the adapter, placing a ferromagnetic cookware on one of the surfaces mentioned above will cause an insignificant change (less than a percent) in the current consumption of the induction device, while placing non-magnetic cookware such as copper, aluminum or glass utensils on the adapters will not create any fluctuations in the current and will allow the device to be used by the most strict observants of the laws of the Jewish Halacha.Furthermore, the present invention provides a dedicated controller. The dedicated controller includes a timer and makes it possible to control the induction and carry out future programming for the activation of the induction, at times and cycles of operation to be determined in advance by the operator before the entrance of the Shabbat or holiday and at an intensity determined in advance by the operator, and all this without human contact during the operation of the device. To remove doubt, the operator can pre-program operating cycles that include the activation time, the duration of the device's operating time, the device's operating power, the length of the operating time, the power during operation, and the downtime between one cycle and the next.The induction device includes a display panel, which may show the intensity of the current supplied by the coil. Before entering the Sabbath or holiday, activation of the dedicated controller disables the main controller and the activation buttons. The disconnection is designed to prevent electrical operation by accidental contact.The dedicated controller allows, by planning in advance, to control the supply of current to the coil, and controls the heat level of cooking utensils, in predetermined cycles. This dedicated controller in the adapter phase allows the user to take pots out of refrigerators and heat them to the desired temperature at the desired time, all in accordance with the Jewish Halacha.Furthermore, the present invention provides an acoustic warning mechanism and a warning light that provide the operator with an indication of whether there is electricity flowing in the coil, regardless of the temperature at which the heating surface or cooking utensils are. This mechanism allows the operator to know when to place or remove the cookware on the adapter for cooking. It will be clarified that the solution refers to the situation where the generator supplies or disables power to the coil. In this mode, a warning is activated on the start and stop of the power flow to the coil. If power is supplied to the coil, an optical signal may be activated such as a red light that warns that the coil is receiving power.Furthermore, the present invention also solves the technical problem of enabling automatic restart of the induction type cooking device when there is a power outage on Shabbat or a holiday while cooking or heating.On the one hand, in the event of a power outage, the power supply to the induction appliance is interrupted and all electrical appliances, including the induction appliances, stop working, and the cooking process stops. On the other hand, when the electricity supply returns, in existing devices, for the induction devices to start working again, the default requires the user to manually activate the induction device and manually determine the operating power. This default, which on days other than Saturdays and holidays (hereafter weekdays) does not constitute a difficulty, is not possible on Saturdays and holidays according to the commandments of Jewish law.The technical solution to the above mentioned problem is that in the event of an external power outage, when the power supply returns, an initialization component which is provided in the induction cooking device checks the last operating state of the device and only if the device isin a special operating mode on Saturdays and holidays, the device will restart the current supply to the coil according to the power programmed in advance by the operator.The initialization component has an autonomous power supply (for example, a battery), which allows the renewal of the current supply to the coil according to the programming determined in advance by the operator.Another technical problem revealed by the present invention is to enable cooking on holy "good days" using the induction cooking device without any human intervention.Furthermore, the present invention provides a lid for a cooking vessel where the lid contains a temperature sensor as well as a communication component such as a Wi-Fi™ component. The temperature sensor measures the temperature inside the pot and the communication component allows the information from the measurement to be transferred to the controller in the induction device. The controller in the induction cooking device may change the heating intensity of the coil under the pot according to the information received from the sensor and according to the cooking programming. The lid is designed so that the temperature sensor can be removed from the lid to allow the lid to be washed in water or in a dishwasher.The strict observants of Jewish Shabbat commandments keep the heating element running continuously for several days. Therefore, another technical problem solved by the present invention is to prevent heating of ceramic surfaces under which induction is installed when the induction is running for several days. When cooking with ferromagnetic pots on ceramic surfaces, the ferromagnetic cookware reflects heat downwards, causing the ceramic surfaces to heat up.Furthermore, the technical solution to the above-mentioned problem is the use of an adapter which is designed to prevent the heating of the ceramic surface. The adapter is constructed of two layers of heat-resistant plastic material such as poly etheretherketone (PEEK), with an insulation layer such as ceramic wool in between, and legs under the adapter that create an insulation layer from air.Furthermore, another_technical solution to the above-mentioned problem is the use of an adapter which is designed to prevent the heating of the ceramic or glass surface by cooling the space below the adapter. The cooling is carried out by means of at least one fan that receives feed from a coil that converts the magnetic induction of the induction coil into a current withan intensity adjusted to the fan. The fan circulates cold air in the space between the surface on which the pot rests and the surface above the induction coil.BRIEF DESCRIPTION OF DRAWINGSThe present disclosed subject matter will be more fully understood and appreciated from the following detailed description taken in conjunction with the drawings wherein corresponding or similar numerals or characters designate corresponding or similar components.

Although some modes of carrying out the present disclosure have been disclosed, those skilled in the art would recognize that other embodiments for carrying out or practicing the present disclosure are also possible. The terminologies “induction cooking device”, “cooking device”, “device” have been used interchangeably throughout this disclosure. The terminologies “cookware”, “pot”, “cooking utensil” have been used interchangeably throughout this disclosure.Figure 1 depicts an exemplary existing conventional induction cooking device (100) without the additions of the present invention. The conventional induction device (100) comprises a surface (2), a copper coil (3), an electronic generator (4), a main controller (5) and a digital power display (7).The surface (2) allows the transfer of magnetic induction in an effective way and is usually made of glass. Under the surface (2) is installed the copper coil (3) that produces the electromagnetic induction that causes a ferromagnetic cookware to heat up. The coil (3) is powered by the electronic generator (4) which provides electric power to the coil (3). Usually installed under the surface is a main controller (5) which activates the induction system and adjusts the heating intensity. The main controller (5) is used to activate the device (100). The induction cooking device (100) receives power from an external voltage source (6).The induction cooking device (100) is adapted to heat, e.g., the cooking utensil (1) placed on a surface (2). Ferromagnetic cookware must be used with the cooking device (100).Figure 2 illustrates a schematic illustration of an induction cooking device (200) in accordance with embodiments of the present invention. The induction cooking device (200) comprises a surface (2), a copper coil (3), an electronic generator (4), a main controller (5) and a digital power display (7).The surface (2) allows the transfer of magnetic induction in an effective way and is usually made of glass. Under the surface (2) is installed the copper coil (3) that produces theelectromagnetic induction that causes the ferromagnetic cookware to heat up. The coil (3) is powered by the electronic generator (4) which provides power to the coil (3). Usually installed under the surface is a main controller (5) which activates the induction system and adjusts the heating intensity. The main controller (5) is used to activate the induction cooking device (200). The induction cooking device (200) receives power from the external voltage source (6).The induction cooking device (200) also comprises the following components for operating the device (200) on Shabbats and holidays according to the laws of Jewish Commandments: a dedicated controller (8), adapters (11 or 12 or 19), warning devices controller (9), warning devices (13, 14), e.g., light and spiker, temperature sensor (601) and initialization (boot) component (10).The dedicated controller (8) is programmed to operate on Saturdays and holidays in a special operating mode. The dedicated controller (8) can be programmed ahead of time before Saturdays and holidays. The programming can include, for example, the number of operating cycles that the operator chooses, the intensity that the coil (3) will provide, the length of time that the coil (3) will be activated, as well as the length of time between operating cycles.The adapters (11, 12, 19) are located under the cooking utensil (1), and above the surface (2) and allow cooking with ferromagnetic cookware or non-ferromagnetic cookware.The adapter (12) contains a layer of iron or an alloy that includes iron and on top of it a copper or aluminum plate. When the coil (3) receives power from the generator (4) a magnetic field is created which causes the iron in the adapter to heat up. The heated iron heats the copper or aluminum layer and makes it possible to heat the cookware that is placed on the adapter without the placing or lowering of the cookware creating a change in the electric current.The dedicated controller (8) activates the generator (4) at the pre-programmed hours, thus causing the adapter to heat up and allowing the cookware that is placed on the adapter to be heated at designated hours without the cookware's placement causing a change in the electric current.In this way, placing the cookware on or lifting it from the adapter (12) does not fundamentally change the electricity consumption and thus allows the heating of food on Shabbat and holidays according to the laws of Jewish Commandments. A copper or aluminum plate may be used to dissipate heat, which will allow for an increase in the consumer's usable surface.The adapter (11) contains a layer of iron or an alloy that includes iron and does not contain a copper or aluminum plate. Adapter (11) allows cooking (and not just heating) so that placing the cooking utensils on or lifting them from the adapter does not fundamentally change the electricity consumption and thus allows cooking on holidays according to the laws of Jewish Commandments. (According to the laws of Jewish Halacha, the user can cook food on the holidays, while on Shabbat the user can only heat the food, and all this on the condition that the user does not cause a change in the electric current of the heating device).Those who are strict in observing Shabbat commandments leave the heating element running continuously for several days. Another technical problem solved by the present invention is how to prevent heating of ceramic surfaces under which an induction is installed when the induction is running for several days. When cooking with ferromagnetic pots on ceramic surfaces, the ferromagnetic cookware reflects heat downwards, causing the ceramic surfaces to heat up.The adapter (19) is made of 3 layers. An upper layer of heat-resistant plastic material such as poly ether ether ketone (PEEK), an intermediate layer of insulating material such as ceramic wool, and a layer of lower plastic material that includes at least two legs whose purpose is to isolate the entire adapter from the surface of the ceramic material (2) and allow the long cooking.The warning device controller (9) is designed to cause a warning light (13) and a warning through the acoustic signal (14) to be turned on without human contact while the generator (4) supplies power to the coil (3) in the special operating mode where the device (200) is controlled by the dedicated controller (8) and in accordance with the operating plan of the induction device on Shabbat and holidays.The warning device controller (9) turns off the warning light (13) and sounds an acoustic warning through an acoustic signal (14) without human contact, when the generator system (4) cuts the power to the coil (3) in accordance with the operation plan of the induction device (200) on Shabbat and holidays. The initialization (boot) component (10) and / or the dedicated controller (8) may comprise a backup battery and a boot controller (not shown in the figure).On weekdays, when the operation of the induction cooking device (200) is stopped due to a power outage, the device (200) operates according to the default and turns itself off. Manual intervention is required to restart the device (200).When there is a power outage on holidays and Shabbat, the initialization (boot) component (10) is activated when the power restores. The initialization (boot) component (10) is designed to check if the dedicated controller (8) is on "Shabat" state when the current supply is restored. In cases where the dedicated controller (8) is on "Shabat" state, the initialization (boot) component (10) restarts the operation of the device (200) in the state in which the system operated when the electric current was interrupted, according to the programming that the operator chose using the dedicated controller (8).The device (200) is adapted to heat ferromagnetic cookware and alternatively, non-magnetic cookware, which are placed on the adapter (11 or 12).The device (200) can include a temperature sensor (601) that enables precise control of the controllers (8) (5) of the intensity of the coil. The temperature sensor (601) makes it possible to pre-program a change in the cooking intensity and to control the cooking intensity using the information sent from the temperature sensor to the controllers (8) (5). The temperature sensor (601) can be wired or wirelessly connected to the device (200).In some embodiments, the device (200) may also comprise a communication unit such as WiFi™ or BLUETOOTH™ for communicating with the sensor (601). The main controller (5) or another additional controller or the dedicated controller may be programmed to control the cooking intensity according to the information received from the temperature sensor located, for example, on the lid of a cooking pot and according to a cooking program.Figure 3 illustrates a schematic illustration of the structure of the adapters 11, 12, and 19 according to certain embodiments of the present invention. The adapters (11, 12 and 19) are placed during operation on the surface (2) above the coil. The adapter (12) is a multilayer adapter and is intended for heating the food on Shabbat. The adapter (11) is a single-layer adapter for cooking on "good days" (holidays). The adapter 19 is a multi-layer adapter designed for heating ferromagnetic cookware on a ceramic surface over induction and designed to prevent the ceramic surface from heating up.The adapter (12) is built from three essential layers and an aesthetic layer. The first layer (121) is used for thermal insulation between the iron layer (122) and the surface layer (2) and is designed to prevent heat loss and warming of the surface (2). The first layer (121) may include at least three legs (193) whose purpose is to isolate the entire adapter from the surface of the ceramic material (2). The iron layer (122) is used on the one hand as an accessory for the coilto provide a continuous current, regardless of placing or lifting cooking utensils on top of it, and on the other hand, the layer is used as an intermediary that heats up to a predetermined temperature, and heats the third layer (123) which serves both as a heat spreader for the second layer (122) and as a surface on which cooking utensils are placed. The third layer (123) is made of aluminum or copper, which are efficient heat spreaders. Above the third layer (123) a user can place another layer of porcelain that will be used for an aesthetic upper visual finish for the adapter.The adapter (11) is made of iron, or composite materials that include iron and is intended for permanent activation of the coil (3), so that it will operate all the time and allow the coil (3) to be activated regardless of the placement of cooking utensils and so that the operation of the coil (3) will not be interrupted when the cooking utensils are lifted. The adapter (11) is also suitable for cooking and not only for heating because there are no additional layers on the iron layer that lower the temperature.The adapter (19) is made of three layers. An upper heat-resistant plastic material layer such as polyether ether ketone (PEEK) (131), an intermediate layer of insulating material such as ceramic wool (132) and a lower plastic material layer (133) that includes at least three legs (193) whose purpose is to isolate the entire adapter from the surface of the ceramic material (2).All layers of material in all adapters are constructed in a way that prevents the passage and penetration of water into the insulation layer, as for example, in soldering the layers together.Figure 4 illustrates a schematic flowchart of the process in the state of recovery from a power failure according to certain embodiments of the present invention. In block 400, the electricity is restored. In block 405, the initialization (boot) component (10) checks if the dedicated controller (8) is in "Shabat" state. If it is in "Shabat" state, in block 415, the initialization (boot) component activates the dedicated controller. In block 420, the dedicated controller activates the device according to the last operating state that preceded the power outage, and the device continues to operate using the dedicated controller and according to the pre-defined plan. If the dedicated controller (8) is not in "Shabat" state, the device stays off (block 410).Figure 5 illustrates a schematic flowchart of an exemplary process while operating an induction cooking device in cycles according to certain embodiments of the present invention.In block 510 the operator programs the device to operate in predefined time frames. For example, the device is programmed to operate on Shabbat between 9 and 10 in the morning and 12 and 2 in the afternoon and not to operate during the rest of the Shabbat hours. In block 515, which occurs upon entering the Sabbath, the dedicated controller operates according to the operation plan programmed in block 510, disconnects the generator and disables the main controller. In block 517, which occurs before 9 o'clock in the morning, the user places the cookware on the device. In block 520, which occurs at 9 o'clock in the morning, the dedicated controller sends an instruction to turn on the generator and the device activation alerts, e.g., a light and a sound. In block 525, which occurs between 9 and 10 o'clock in the morning, the device heats the cookware until the cooking is ready and the cookware may be removed from the device. In block 530, which occurs at 10 o'clock in the morning, the dedicated controller may activate a buzzer for a limited time and turns off the alerts and the generator. In block 535, which occurs before 12 o'clock, the user places the cookware on the device. In block 540, which occurs at 12 o'clock, the dedicated controller sends an instruction to turn on the generator and the device activation alerts, e.g., a light and a sound. In block 545, which occurs between 12:00 and 2:00 in the afternoon, the device heats the cookware until the cooking is ready and the cookware may be removed from the device. In block 550, which occurs at 2:00 in the afternoon, the dedicated controller may activate a buzzer for a limited time and turns off the alerts and the generator.Figure 6 illustrates a schematic illustration of a lid for a cooking utensil comprising a temperature sensor for the purpose of controlling the intensity of the induction device according to the measured temperature and the programming, according to certain embodiments of the present invention.
[0065] The lid (600) can be made, for example, of glass or stainless steel. The lid (600) includes a removable element (610) such as a handle. The removable element comprises a communication element (605) and a sensor (601). The communication element (605) can be Wi-Fi™ or BLUETOOTH™ component. The sensor (601) is used to measure the temperature inside the cookware on which the lid (600) is placed. The communication element (605) is used to transmit the temperature information to the induction device (200), e.g., using the communication unit in the induction device. The lid (600) may comprise an opening (603) through which the sensor (601) may be inserted. Before washing the lid, the removable element(610) can be pulled out of the lid (for example, by turning the handle) to prevent it from getting wet.Figure 7 illustrates a schematic flowchart of a cooking process with temperature control without human intervention according to certain embodiments of the present invention.In block 710, a user programs the device to a cooking or heating program suitable for the dish. For example, the user can program the device's turn-on time. For example, the user can program the device to heat the cookware to a temperature of 30 degrees and then maintain this temperature for 10 minutes and then automatically turn off the device. In block 715, the user places the cookware on the device. In block 720, the main controller (5) activates the selected cooking program. In block 725, the controller periodically receives (for example, every second) the temperature inside the cookware that is sent from the temperature sensor. In block 730, the controller of the device regulates the heating intensity of the induction according to the temperature of the cookware and according to the cooking program. In block 735, the controller turns off the device according to the cooking program.Figure 8 illustrates a schematic illustration of a side view of another adapter (21) with a fan for cooling the upper surface of an induction cooking device, according to certain embodiments of the present invention. The adapter (21) comprises the following elements: an iron layer (11) on top of which is a glass layer (806), at least two legs (193), one or more fans (810), one or more adapter coils (808), one or more adapters' cards (805), and one or more adapter lifting handles (804).The fans (810) (two are shown) are used to disperse an air current (809) in the space between the adapter surface (11 or 806) on which the cookware is placed and the induction surface (2), below which the induction coil (3) is located. When cooking with ferromagnetic pots on ceramic surfaces, the ferromagnetic cookware or the iron layer (11) of the adapter reflects heat downwards, causing the ceramic surfaces to heat up. Those who are strict in observing Shabbat commandments leave the heating element running continuously for several days, which causes the ceramic surface to heat up. The air flow (809) that comes out of the fans (810) can be used to prevent the heating of ceramic surfaces under which induction (200) is installed, when the induction works for several days.The fan can be a blower such as a 12-volt induction blower. The fan (blower) (810) receives power from the magnetic induction produced by the induction coil (3) as follows: the adaptercoils (808) convert the magnetic induction produced by the coil (3) into electric current. The adapter coils (808) are connected by an electrical wire to the adapter card (805) which adjusts the power to the power required for the fan (810) to operate the fan (810). The adapter card (805) is connected by an electrical wire to the fan 810 for the purpose of supplying the required power to the fan (810).Figure 9 illustrates a schematic illustration of a top view of an adapter (21) with a fan to cool the upper surface of an induction cooking device according to certain embodiments of the present invention. The adapter (21) comprises two fans for illustration purposes only. The figure shows the adapter (21) in view from above, the adapter coils (808), the adapter cards (805) that are connected the coils (808), the handles (804) for lifting the adapter, and the glass of the adapter (806). The air stream (809) that comes out of the fans (810) is also shown.The terminology used herein is for the purpose of describing certain embodiments only and is not intended to limit the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will further be understood that the terms "including" and / or "including", when used in this specification, indicate the presence of features, integers, steps, operations, elements and / or components, but do not exclude the presence or adding one or more attributes, integers, steps, operations, elements, components and / or groups thereof.It should be noted that in some alternative implementations, the functions specified in the block may occur out of the order specified in figures. For example, two blocks presented in sequence may, in fact, be executed simultaneously, or the blocks may sometimes be executed in reverse order, depending on the functionality involved.
