Description
The present invention relates to an induction heating cooker that is enabled to operate in a safe manner.
The induction heating cooker functions according to the principle of heating a cast iron or steel ferromagnetic cooking vessel with the magnetic field generated by the induction coil. Since the heat required for cooking is not produced in the gas or electric burners on the cooker but directly on the cooking vessel, energy efficiency of the induction heating cookers is very high. In order to drive the induction coils creating magnetic field, a large amount of electric current is passed through the electronic switching elements such as IGBT (Insulated Gate Bipolar Transistor) and diode bridge on the electronic card, and therefore, the said switching elements overheat. In order for the switching elements to operate safely, an efficient cooling system is required.
The temperature of the switching elements must be kept under control in order to enable the induction heating cooker to operate under safe conditions. When the switching elements reach the critical temperature defined by the producer, the current passed therethrough is cut by the control unit.
In the state of the art European Patent Application No. EP1936283, a cooking appliance is disclosed, comprising a flow guide that is disposed on the heat sink so as to cover at least a portion thereof and that guides a portion of the cooling air to flow to the heating element.
The aim of the present invention is the realization of an induction heating cooker that is enabled to operate in a safe manner by providing an efficient cooling.
The induction heating cooker realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a top plate that is produced from a material such as glass or ceramic; a plurality of induction coils that are disposed under the top plate and that enable the ferromagnetic cooking vessel placed thereon to be heated with the magnetic field created by the induction coils; at least one electronic card that enables the induction coils to be energized; a plurality of switching elements that are connected to the electronic card, that carry electric current and that heat up with the effect of the carried current, and at least one heat sink that provides the cooling of the switching elements.
The induction heating cooker of the present invention comprises a cooling system having
- a refrigerant line that is disposed in the heat sink,
- a pump with one end connected to the refrigerant line, the pump enabling the refrigerant fluid to be compressed and circulated in the refrigerant line, and
- a fan group having at least one fan, that enables the refrigerant fluid heating up while passing through the refrigerant line to be cooled and delivered to the pump.
The refrigerant fluid that is delivered to the refrigerant line by means of the pump that is preferably of the solenoid type draws heat from the switching elements while moving inside the heat sink and thus cools the switching elements. The refrigerant fluid that heats up after leaving the heat sink is carried to the fan group by means of the refrigerant line, cooled again by the fan group and delivered to the pump. By means of the refrigerant line that has preferably a plurality of bends in the fan group, the refrigerant line is enabled to be efficiently cooled and delivered to the pump by means of the fan group.
In an embodiment of the present invention, the cooling system comprises the refrigerant line having
- at least one inlet refrigerant tube with one end connected to the pump, the inlet refrigerant tube extending parallel to the switching elements, and
- at least one return refrigerant tube with one end connected to the fan group, the return refrigerant tube extending parallel to the inlet refrigerant tube. The inlet refrigerant tube, that is produced from a material with high thermal conductivity and that is positioned such that a distance predetermined by the producer remains between the inlet refrigerant tube and each of the switching elements arranged side by side on the electronic card, provides an efficient heat transfer between the refrigerant fluid and the switching elements. The refrigerant fluid heating up by drawing heat from the switching elements is passed through the return refrigerant tube positioned away from the switching element so as to prevent heat transfer between the switching elements and the refrigerant fluid, and thus delivered to the fan group. In an embodiment of the present invention, the induction heating cooker comprises the switching elements disposed at both sides of the heat sink, two inlet refrigerant tubes that extend on the sides of the heat sink where the switching elements are disposed, and two return refrigerant tubes that extend between the inlet refrigerant tubes.
In another embodiment of the present invention, the induction heating cooker comprises a temperature sensor that is disposed on the heat sink, and a control unit that compares the temperature value measured by the temperature sensor with the limit temperature value predetermined by the producer and thus controls the activation or deactivation of the cooling system. By means of the temperature sensor that is preferably a NTC or PTC sensor, the control unit controls the temperature of the switching elements during the operation of the induction heating cooker.
In another embodiment of the present invention, the control unit operates the pump and the fan group so as to activate the cooling system if the temperature value measured by the temperature sensor is higher than the limit temperature value. When the measured temperature value exceeds the limit temperature value, it is detected that the switching elements and the induction coils disposed in the vicinity of the switching elements are overheated. In order to prevent the deactivation of the switching elements and the induction coils due to overheating, the control unit activates the cooling system and operates the pump and the fan group. Thus, by preventing the deactivation of the switching elements and the induction coils, the induction heating cooker is enabled to be continuously operated and the operational performance of the induction heating cooker is improved.
In another embodiment of the present invention, the control unit enables the fan RPM to be changed according to the temperature value measured by the temperature sensor. The control unit compares the measured temperature value with the limit temperature value and evaluates the need for cooling the switching elements. As the difference between the measured temperature value and the limit temperature value increases, the control unit increases the fan RPM, thus the refrigerant in the refrigerant line is cooled better and the switching elements are enabled to be cooled to temperatures below the limit temperature value by means of the cooling system.
In another embodiment of the present invention, the control unit stops the pump and the fan group so as to deactivate the cooling system if the temperature value measured by the temperature sensor is lower than the limit temperature value. While the measured temperature value is below the limit temperature value, the induction heating cooker is enabled to be operated at the safe temperature value. Therefore, when the measured temperature value falls below the limit temperature value, the control unit stops the pump and the fan group so as to deactivate the cooling system. Thus, the cooling system is prevented from being operated when not needed and the lifespan of the cooling system is improved.
By means of the present invention, an induction heating cooker is realized, wherein the switching elements are efficiently cooled by using liquid refrigerant fluid.

The induction heating cooker (1) comprises a top plate (3) that is produced from a material such as glass or ceramic; a plurality of induction coils (2) that are disposed under the top plate (3) and that enable the ferromagnetic cooking vessel placed thereon to be heated with the magnetic field created by the induction coils (2); at least one electronic card (4) that enables the induction coils (2) to be energized; a plurality of switching elements (5) that are connected to the electronic card (4), that carry electric current and that heat up with the effect of the carried current, and at least one heat sink (6) that provides the cooling of the switching elements (5). The switching elements (5) are elements preferably such as IGBT (Insulated Gate Bipolar Transistor) and diode bridge, that carry high current and that overheat due to the current (Figure 1 and Figure 2).
The induction heating cooker (1) of the present invention comprises a cooling system (10) having
- a refrigerant line (7) that is disposed in the heat sink (6),
- a pump (8) with one end connected to the refrigerant line (7), the pump (8) enabling the refrigerant fluid to be compressed and circulated in the refrigerant line (7), and
- a fan group (9) that enables the refrigerant fluid heating up while passing through the refrigerant line (7) to be cooled and delivered to the pump (8).
The refrigerant fluid delivered to the refrigerant line (7) by the pump (8) moves along the refrigerant line (7) positioned close to the switching elements (5), and by means of the heat transfer between the refrigerant line (7) and the switching elements (5), the switching elements (5) are cooled. The refrigerant fluid moving and heating up along the refrigerant line (7) is delivered to the fan group (9) and after being cooled again by means of the fan group (9), is carried back to the pump (8) so as to be delivered to the refrigerant line (7) again. Thus, the switching elements (5) are enabled to be efficiently cooled by means of the closed cycle cooling system (9) (Figure 3 and Figure 5).
In an embodiment of the present invention, the cooling system (10) comprises the refrigerant line (7) having
- at least one inlet refrigerant tube (11) with one end connected to the pump (8), the inlet refrigerant tube (11) extending parallel to the switching elements (5), and
- at least one return refrigerant tube (12) with one end connected to the fan group (9), the return refrigerant tube (12) extending parallel to the inlet refrigerant tube (11). The refrigerant fluid carried along the inlet refrigerant tube (11) positioned to be distanced from the switching elements (5) so as to allow heat transfer draws heat from the switching elements (5), thus enabling the switching elements (5) to be cooled. The refrigerant fluid heating up in the inlet refrigerant tube (11) is delivered to the return refrigerant tube (12) extending parallel to the inlet refrigerant tube (11) and passed through the return refrigerant tube (12) to be carried to the fan group (9). In this embodiment, the inlet refrigerant tube (11) is positioned between the switching elements (5) and the return refrigerant tube (12), and by means of this positioning, the occurrence of heat transfer between the switching elements (5) and the return refrigerant tube (12) is prevented. Thus, the refrigerant fluid delivered to the return refrigerant tube (12) after heating up in the inlet refrigerant tube (11) is prevented from heating the switching elements (5) (Figure 5).
In another embodiment of the present invention, the induction heating cooker (1) comprises a temperature sensor (13) that is disposed on the heat sink (6), and a control unit (14) that compares the temperature value (Tind) measured by the temperature sensor (13) with the limit temperature value (Tlim) predetermined by the producer and thus controls the activation or deactivation of the cooling system (10). The control unit (14) detects the temperature of the switching elements (5) by means of the temperature sensor (13) disposed on the heat sink (6). By comparing the measured temperature value (Tind) with the limit temperature value (Tlim), the control unit (14) determines the need for cooling the switching elements (5) and controls the activation/deactivation of the cooling system (10) according to the cooling need (Figure 4 and Figure 5).
In another embodiment of the present invention, the control unit (14) operates the pump (8) and the fan group (9) so as to activate the cooling system (10) if the temperature value measured (Tind) by the temperature sensor (13) is higher than the limit temperature value (Tlim). If the measured temperature value (Tind) is above the limit temperature value (Tlim), the cooling system (10) is operated, thus preventing the switching elements (5) from overheating and being damaged.
In another embodiment of the present invention, the control unit (14) enables the fan RPM (Vfan) to be changed according to the temperature value measured (Tind) by the temperature sensor (13). In this embodiment, in the control unit (14), the producer defines different fan RPMs (Vfan) corresponding to certain temperature value ranges. By comparing the temperature value measured (Tind) by the temperature sensor (13) with the predefined temperature value ranges, the control unit (14) provides that the fan RPM (Vfan) corresponding to the measured temperature value (Tind) and that the fan group (9) is operated at the determined fan RPM (Vfan). As the measured temperature value (Tind) increases, the fan RPM (Vfan) also increases, and thus, the refrigerant fluid is enabled to be efficiently cooled by the fan group (9). Thus, the cooling performance of the cooling system (10) is improved, and by preventing the switching elements (5) from overheating, safe operation conditions are created for the user.
In another embodiment of the present invention, the control unit (14)stops the pump (8) and the fan group (9) so as to deactivate the cooling system (10) if the temperature value measured (Tind) by the temperature sensor (13) is lower than the limit temperature value (Tlim). When the measured temperature value (Tind) falls below the limit temperature value (Tlim), the control unit (14) determines that the switching elements (5) do not need to be cooled and deactivates the cooling system (10). Thus, by preventing the cooling system (10) from being continuously operated, the energy consumption of the induction heating cooker (1) is increased.
In the induction heating cooker (1) of the present invention, by means of a control method executed by the control unit (14) and comprising the steps of
- Measuring the temperature of the switching elements (5) by means of the temperature sensor (13),
- comparing the measured temperature value (Tind) with the limit temperature value (Tlim),
- starting the pump (8) and the fan group (9) if the measured temperature value (Tind) is higher than the limit temperature value (Tlim),
- Comparing the measured temperature value (Tind) with the temperature value ranges predetermined by the producer,
- operating the fan group (9) at the fan RPM (Vfan) corresponding to the detected temperature value range,
- stopping the pump (8) and the fan group (9) if the measured temperature value (Tind) is lower than the limit temperature value (Tlim),
the switching elements (5) are enabled to be efficiently cooled.
In the induction heating cooker (1) of the present invention, the switching elements (5) are enabled to be efficiently cooled by means of the refrigerant fluid carried through the cooling system (10). Thus, by preventing the switching elements (5) from overheating, safer usage conditions for the user are created in the induction heating cooker (1).
