The exhaust device 1000 may determine the output RPM of the fan motor based on the sensor value of the RPM sensor 2440 and periodically transmit the determined RPM to the heating device 2000.

The heating device 2000 may determine whether the filter needs to be replaced based on the output RPM and target RPM of the fan motor.

As foreign matter accumulates in the filter 50, the amount of air passing through the filter decreases, thereby reducing the load on the fan motor. Therefore, even if the same fan motor driving voltage is applied, the output RPM of the fan motor increases as foreign matter accumulates in the filter 50. Therefore, when the heating device 2000 applies the driving voltage corresponding to the target RPM to the fan motor, if the steady-state RPM value of the fan motor increases from the target RPM to more than the reference RPM, foreign matter in the filter 50 exceeds the reference amount. As it builds up, you may decide that the filter needs replacement.

Based on determining that the output RPM of the fan motor is greater than or equal to the threshold RPM, the heating device 2000 may determine that a filter replacement is necessary.

Additionally, the heating device 2000 may determine the degree of contamination of the filter based on the ratio of the output RPM of the fan motor and the critical RPM.

In step S1080, the heating device 2000 may display whether the filter needs to be replaced.

Based on determining that the filter needs to be replaced, the heating device 2000 may display an image or text indicating that the filter needs to be replaced.

Additionally, the exhaust device 1000 may transmit the sensor value of the wind volume sensor 2430 to the heating device 2000 through a short-distance wireless communication connection. Additionally, when the received sensor value of the air volume sensor 2430 is lower than the threshold air volume value, the heating device 2000 may determine that there is a problem with the installation of the flow path.

Additionally, the heating device 2000 may output a notification indicating that there is an error in the installation of the flow path.

Additionally, the heating device 2000 may store a critical air volume value. The critical air volume value may be a measurement value of the air volume generated by the fan when the fan motor is driven at a standard RPM when the installation of the heating device 2000 and the flow path deviates from the recommended installation method by more than a standard degree.

Additionally, as the installation of the flow path differs from the recommended installation method, the load on the fan motor may also increase or decrease. As the load on the fan motor also increases or decreases, the output RPM of the fan motor may increase or decrease even if the same drive is applied to the fan motor.

For example, the target RPM of the fan motor may be stored in response to the amount of oil vapor, and the target RPM of the fan motor may be stored in response to the amount of odor particles. In this case, even if the total amount of fine particles is large, if most of the fine particles are water vapor, the target RPM of the fan motor may be low.

Accordingly, the heating device 2000 may obtain the target RPM of the fan motor based on the amount of fine particles detected through the fine particle sensor.

According to one embodiment, when more air is sucked into the exhaust opening due to the driving of the fan motor, more fine particles may be detected per unit volume by the fine particle sensor even if the same amount of fine particles is present.

A fuse and relay may be provided between the EMI filter 2111 and the external power source to block overcurrent. AC power from which high-frequency noise has been blocked by the EMI filter 2111 is supplied to the rectifier circuit 2112.

The rectifier circuit 2112 can convert alternating current power into direct current power. For example, the rectifier circuit 2112 converts an alternating current voltage whose size and polarity (positive or negative voltage) changes over time into a direct current voltage whose size and polarity are constant, and whose size and direction (positive or negative voltage) changes over time. An alternating current (current or negative current) that varies can be converted into a direct current with a constant magnitude. Rectifier circuit 2112 may include a bridge diode. For example, rectifier circuit 2112 may include four diodes. A bridge diode can convert an alternating current whose polarity changes over time into a positive voltage whose polarity is constant, and can convert an alternating current whose direction changes over time into a positive current whose direction is constant. The rectifier circuit 2112 may include a DC link capacitor.

The first switch and the second switch may be turned on or off according to a driving control signal from the driving processor 2116.

The inverter circuit 2113 can control the current supplied to the transmission coil 2011. For example, the magnitude and direction of the current flowing through the transmission coil 2011 may change depending on the turn-on/turn-off of the first and second switches included in the inverter circuit 2113. In this case, alternating current may be supplied to the transmission coil 2011. Alternating current in the form of a sine wave is supplied to the transmission coil 2011 according to the switching operations of the first switch and the second switch. In addition, the longer the switching period of the first switch and the second switch (e.g., the smaller the switching frequency of the first switch and the second switch), the larger the current supplied to the transmission coil 2011 may be. The intensity of this output magnetic field (output of the heating device 2000) may increase. The transmitting coil 2011 may also be called an operating coil in that it generates a heating operation by forming a magnetic field.

The driving processor 2116 may generate a driving control signal for turning on/off the switching circuit according to the determined switching frequency.

The transmitting coil 2011 can generate a magnetic field to heat the cooking vessel. For example, when a driving current is supplied to the transmission coil 2011, a magnetic field may be induced around the transmission coil 2011. When a current whose size and direction changes with time, that is, an alternating current, is supplied to the transmitting coil 2011, a magnetic field whose size and direction changes with time may be induced around the transmitting coil 2011. The magnetic field around the transmitting coil (2011) can pass through a top made of tempered glass and reach the cooking vessel placed on the top. Due to a magnetic field whose size and direction changes with time, an eddy current that rotates around the magnetic field may be generated in the cooking vessel, and electrical resistance heat may be generated in the cooking vessel due to the eddy current. Electric resistance heat is the heat generated in a resistor when a current flows through it, and is also called Joule heat. The cooking vessel is heated by electrical resistance heat, and the contents within the cooking vessel may be heated.
