技术领域technical field
本发明涉及家用电器技术领域，特别涉及一种电磁炉的放电方法和一种采用该放电方法的电磁炉。The invention relates to the technical field of household appliances, in particular to a discharge method for an electromagnetic cooker and an electromagnetic cooker using the discharge method.
背景技术Background technique
目前，国家标准或者欧洲标准对电磁炉掉电后的放电的要求为：电磁炉在掉电1秒内的残余电量电压要小于34V。现有技术中，一般采用放电电阻为电磁炉放电。但是，使用放电电阻放电，放电电阻的大小会影响电磁炉的放电速度，例如，使用大阻值放电电阻则放电电流小就会导致放电时间长，不能够实现快速放电，而使用小阻值放电电阻，会导致电磁炉的待机功耗增大，因而又难以满足国家标准或者欧洲标准对电磁炉待机功耗标准的要求。At present, the national standard or European standard requires the discharge of the induction cooker after power-off: the residual power voltage of the induction cooker within 1 second of power-off should be less than 34V. In the prior art, a discharge resistor is generally used to discharge the induction cooker. However, when using a discharge resistor to discharge, the size of the discharge resistor will affect the discharge speed of the induction cooker. For example, if a discharge resistor with a large resistance value is used, the discharge current will be small and the discharge time will be long, and rapid discharge cannot be achieved. , will lead to an increase in the standby power consumption of the induction cooker, so it is difficult to meet the requirements of the national standard or European standard for the standby power consumption of the induction cooker.

On the contrary, the embodiments of the present invention include all changes, modifications and equivalents coming within the spirit and scope of the appended claims.
下面参照附图1至附图3描述根据本发明实施例提出的一种电磁炉的放电方法。A discharge method for an electromagnetic oven according to an embodiment of the present invention will be described below with reference to accompanying drawings 1 to 3 .
如图1所示，本发明实施例的电磁炉的放电方法包括以下步骤：As shown in Figure 1, the discharge method of the electromagnetic oven of the embodiment of the present invention comprises the following steps:
S101，检测电磁炉的电压。S101, detecting the voltage of the induction cooker.
其中，检测的电磁炉的电压通常是市电经电压检测电路处理后形成的采样电压。Wherein, the detected voltage of the induction cooker is usually a sampling voltage formed after the mains power is processed by the voltage detection circuit.
S102，根据电磁炉的电压判断电磁炉是否处于掉电状态。S102, judging whether the induction cooker is in a power-off state according to the voltage of the induction cooker.
根据步骤S101检测的电磁炉的电压判断电磁炉是否处于掉电状态，如果是，则进入步骤S103，如果否，则返回步骤S101。According to the voltage of the induction cooker detected in step S101, it is judged whether the induction cooker is in a power-off state, if yes, proceed to step S103, if not, return to step S101.
在电磁炉掉电之后，步骤S101检测的电磁炉的电压会有衰减的波动，可以根据电磁炉掉电之后检测的电压的波动来判断电磁炉是否处于掉电状态，具体判断过程以下有详细说明。After the induction cooker is powered off, the voltage of the induction cooker detected in step S101 will fluctuate attenuation. Whether the induction cooker is in a power-off state can be judged according to the voltage fluctuation detected after the induction cooker is powered off. The specific judgment process is described in detail below.
S103，控制电磁炉的风机启动以使电磁炉进行放电。S103, controlling the fan of the induction cooker to start to discharge the induction cooker.
如果通过步骤S102判断电磁炉处于掉电状态，则控制电磁炉的风机启动。因为在电磁炉处于掉电状态时，弱电电路例如+5V电压可以为电磁炉提供一定时间例如2.39秒或者2.5秒的工作时间，在此时间内电磁炉的控制器完全可以进行正常的控制操作，即可以发出控制信号以启动电磁炉的风机。控制风机启动，由电磁炉的电路板中的残余电量为风机供电，从而可以使得电磁炉进行快速放电。同时，可以满足国家标准或者欧洲标准规定的电磁炉放电时间的要求，如图2所示为根据本发明实施例的电磁炉的放电方法对电磁炉进行样机测试的掉电后的电压波形，检测的电磁炉的放电时间为0.396秒，小于0.5秒，满足国家标准或者欧洲标准规定的电磁炉放电时间的要求。If it is determined through step S102 that the induction cooker is in a power-off state, the fan of the induction cooker is controlled to start. Because when the induction cooker is in the power-off state, the weak current circuit such as +5V voltage can provide a certain period of time for the induction cooker, such as 2.39 seconds or 2.5 seconds of working time. During this time, the controller of the induction cooker can perform normal control operations, that is, it can send Control signal to start the fan of the induction hob. The fan is controlled to start, and the residual power in the circuit board of the induction cooker is used to supply power to the fan, so that the induction cooker can be quickly discharged. Simultaneously, can meet the requirement of the induction cooker discharge time of national standard or European standard, as shown in Figure 2, the voltage waveform after the power-off of the prototype test of the induction cooker according to the discharge method of the induction cooker according to the embodiment of the present invention, the detection of the induction cooker The discharge time is 0.396 seconds, which is less than 0.5 seconds, which meets the requirements for the discharge time of induction cookers stipulated by national standards or European standards.
在本发明的一个实施例中，在根据电磁炉的电压判断电磁炉是否处于掉电状态之前还需要检测并判断电磁炉是否处于待机状态，如果电磁炉处于待机状态，则根据检测的电磁炉的电压判断电磁炉是否处于掉电状态，如果判断电磁炉未处于待机状态，则继续进行检测判断电磁炉是否处于待机状态。In one embodiment of the present invention, before judging whether the induction cooker is in the power-off state according to the voltage of the induction cooker, it is necessary to detect and judge whether the induction cooker is in the standby state. If the induction cooker is in the standby state, then judge whether the induction cooker is in the In the power-off state, if it is judged that the induction cooker is not in the standby state, the detection is continued to determine whether the induction cooker is in the standby state.
在本发明的一个具体实施例中，在电磁炉断开与电网的连接时，可以检测到电磁炉的电压衰减波动范围为4..6V～1.8V，所以根据检测的电磁炉的电压可以判断电磁炉是否处于掉电状态。但是，如果电网电压的波动较大例如20V也会出现判断为电磁炉处于掉电状态的情况，为了避免因电网的电压波动误判断电磁炉为掉电状态，在本发明的一个实施例中，在电磁炉处于待机状态时，根据电磁炉的电压判断电磁炉是否处于掉电状态可以包括：连续预设次数地判断电磁炉的电压在预设时间内的波动是否处于第一预设电压范围内。具体地，其中，预设时间可以为0.01～0.8秒，第一预设电压范围可以为5～30V，即言，判断电磁炉的电压在预设时间例如0.01～0.8秒内的电压波动是否在第一预设电压范围例如5～30V内，并且，可以1次或者重复多次例如3次进行判断，如果是，即经过1次或者多次例如3次判断电磁炉的电压在0.01～0.8秒内的波动处于5～30V内，则判断电磁炉处于掉电状态，控制电磁炉的风机启动以使电磁炉进行放电，并在检测到电磁炉的电压在预设时间内的波动未达到第一预设电压范围时，控制风机关闭。否则，即经过1次或多次例如3次判断并不是每次电磁炉的电压在0.01～0.8秒内的波动均处于5～30V内，则判断电磁炉的电压波动为电网波动引起的。优选地，可以判断电磁炉在0.3秒内的电压波动是否大于10V，并且，1次或者重复多次例如3次进行判断，例如如果3次并且每次判断电磁炉在0.3秒内的电压波动均大于10V，则控制电磁炉的风机启动以使电磁炉进行放电，并在检测到电磁炉的电压在预设时间内的波动未达到第一预设电压范围即5～30V时，控制风机关闭。否则，如果经过3次判断并且不是每次例如其中有一次电磁炉在0.3秒内的电压波动小于10V，则判断电磁炉的电压波动为电网波动引起的。In a specific embodiment of the present invention, when the induction cooker is disconnected from the power grid, it can be detected that the voltage attenuation fluctuation range of the induction cooker is 4..6V-1.8V, so it can be judged whether the induction cooker is in the power down state. However, if the fluctuation of the grid voltage is large, for example, 20V, it may be judged that the induction cooker is in a power-off state. When in the standby state, judging whether the induction cooker is in the power-off state according to the voltage of the induction cooker may include: continuously determining whether the fluctuation of the voltage of the induction cooker within a preset time is within a first preset voltage range for preset times. Specifically, the preset time may be 0.01-0.8 seconds, and the first preset voltage range may be 5-30V. A preset voltage range, such as 5 to 30V, and can be judged once or multiple times, such as three times. If so, it is judged that the voltage of the induction cooker is within 0.01 to 0.8 seconds after one or multiple times, such as three times. If the fluctuation is within 5-30V, it is judged that the induction cooker is in a power-off state, and the fan of the induction cooker is controlled to start to discharge the induction cooker, and when it is detected that the voltage fluctuation of the induction cooker within the preset time does not reach the first preset voltage range, Control fan off. Otherwise, it is determined that the voltage fluctuation of the induction cooker is not within 5-30V within 0.01-0.8 seconds after 1 or more times, for example, 3 times, it is judged that the voltage fluctuation of the induction cooker is caused by the fluctuation of the power grid. Preferably, it can be judged whether the voltage fluctuation of the induction cooker is greater than 10V within 0.3 seconds, and the judgment is made once or multiple times such as 3 times, for example, if it is judged 3 times and each time the voltage fluctuation of the induction cooker is greater than 10V within 0.3 seconds , then control the fan of the induction cooker to start to discharge the induction cooker, and when it is detected that the fluctuation of the voltage of the induction cooker within the preset time does not reach the first preset voltage range, that is, 5-30V, the fan is controlled to be turned off. Otherwise, if the voltage fluctuation of the induction cooker is less than 10V within 0.3 seconds after 3 judgments and not each time, for example, the voltage fluctuation of the induction cooker is judged to be caused by the fluctuation of the power grid.
但是，在电磁炉处于待机状态时，如果电网电压出现较大波动例如电网电压波动在20V，而经过上述1次或者多次例如3次判断，电压波动范围仍然满足掉电状态的条件例如电压波动范围大于10V，则会误判断为电磁炉处于掉电状态，因而控制电磁炉的风机启动。为了避免误判断电磁炉处于掉电状态而使风机长时间启动，在本发明的一个实施例中，在风机启动之后，检测电磁炉的电压在预设时间内的波动范围是否达到第一预设电压范围，并在检测到电磁炉的电压在预设时间内的波动未达到第一预设电压范围时，在检测到的电压稳定后控制风机关闭。However, when the induction cooker is in the standby state, if the grid voltage fluctuates greatly, for example, the grid voltage fluctuates at 20V, and after the above-mentioned 1 or more judgments, such as 3 times, the voltage fluctuation range still meets the conditions of the power-off state, such as the voltage fluctuation range If it is greater than 10V, it will be misjudged that the induction cooker is in a power-off state, so the fan of the induction cooker will be controlled to start. In order to avoid misjudging that the induction cooker is in a power-off state and causing the fan to start for a long time, in one embodiment of the present invention, after the fan is started, it is detected whether the fluctuation range of the voltage of the induction cooker reaches the first preset voltage range within a preset time , and when it is detected that the voltage fluctuation of the induction cooker does not reach the first preset voltage range within a preset time, the fan is controlled to be turned off after the detected voltage stabilizes.
在本发明的一个具体实施例中，如图3所示，上述电磁炉的放电过程包括以下步骤：In a specific embodiment of the present invention, as shown in Figure 3, the discharge process of the above-mentioned induction cooker comprises the following steps:
S301，判断电磁炉是否处于待机状态。S301. Determine whether the induction cooker is in a standby state.
处于待机状态时，电磁炉的风机是关闭的，首先判断电磁炉是否处于待机状态，如果电磁炉处于待机状态则进入步骤S302，否则返回，即继续判断电磁炉是否处于待机状态。。When in the standby state, the fan of the induction cooker is turned off. First, it is judged whether the induction cooker is in the standby state. If the induction cooker is in the standby state, then enter step S302. Otherwise, return to continue to judge whether the induction cooker is in the standby state. .
S302，判断电磁炉是否处于掉电状态。S302, judging whether the induction cooker is in a power-off state.
如果通过步骤S301判断电磁炉处于待机状态，则再判断电磁炉是否处于掉电状态，即电磁炉是否从待机状态掉电，如果是，则进入步骤S303，否则返回步骤S301。If it is judged that the induction cooker is in the standby state by step S301, then judge whether the induction cooker is in the power-off state, that is, whether the induction cooker is powered off from the standby state, if yes, then enter step S303, otherwise return to step S301.
S303，控制风机启动以使电磁炉进行放电。S303, controlling the fan to start to discharge the induction cooker.
如果通过步骤S302判断电磁炉处于掉电状态，则控制电磁炉的风机启动以使电磁炉进行放电。当检测到电压稳定后控制风机关闭即进入步骤S304。If it is determined in step S302 that the induction cooker is in a power-off state, the fan of the induction cooker is controlled to start to discharge the induction cooker. When it is detected that the voltage is stable, the fan is controlled to be turned off, and the process proceeds to step S304.
S304，在检测到电磁炉的电压在预设时间内波动未达到第一预设电压范围时，控制风机关闭。S304, when it is detected that the voltage fluctuation of the induction cooker does not reach the first preset voltage range within the preset time, control the fan to turn off.
在风机启动之后，在检测到电磁炉的电压在预设时间内波动未达到第一预设电压范围例如5V～30V时，当放电完成或者电网电压波动稳定之后，控制风机关闭。After the fan is started, when it is detected that the voltage fluctuation of the induction cooker does not reach the first preset voltage range such as 5V-30V within a preset time, when the discharge is completed or the grid voltage fluctuation is stable, the fan is controlled to be turned off.
综上所述，根据本发明实施例的电磁炉的放电方法，在电磁炉掉电之后，控制风机启动，通过电磁炉电路板中储存的电量为风机供电，从而可以使风机转动来实现电磁炉的快速放电，并且满足国家标准或欧洲标准对电磁炉放电的要求，不会增加电磁炉的待机功耗。该方法仅需要在程序上写入，可不用额外增加其他电子元件，成本低。此外，该放电方法操作简单，易实施。In summary, according to the discharge method of the induction cooker according to the embodiment of the present invention, after the induction cooker is powered off, the fan is controlled to start, and the power stored in the circuit board of the induction cooker is used to supply power to the fan, so that the fan can be rotated to realize rapid discharge of the induction cooker. And it meets the requirements of national or European standards for induction cooker discharge, and will not increase the standby power consumption of the induction cooker. This method only needs to be written in the program, without adding other electronic components, and the cost is low. In addition, the discharge method is simple to operate and easy to implement.

在本发明的一个实施例中，控制器404在判断电磁炉是否处于掉电状态之前，先判断电磁炉是否处于待机状态。如果控制器404判断电磁炉处于待机状态，则根据检测的电磁炉的电压判断电磁炉是否处于掉电状态。In one embodiment of the present invention, the controller 404 first determines whether the induction cooker is in a standby state before determining whether the induction cooker is in a power-off state. If the controller 404 judges that the induction cooker is in a standby state, then it is determined whether the induction cooker is in a power-off state according to the detected voltage of the induction cooker.
在本发明的一个具体实施例中，在电磁炉断开与电网的连接时，可以检测到电磁炉的电压衰减波动范围为4..6V～1.8V，所以根据检测的电磁炉的电压可以判断电磁炉是否处于掉电状态。控制器404在判断电磁炉处于掉电状态时，发出控制信号至风机控制电路403以控制电磁炉的风机402启动，从而通过风机402消耗电磁炉掉电后电路板中残余的电量。在电磁炉掉电之后，电压检测电路401检测的电磁炉的电压会有衰减的波动，控制器404可以根据电磁炉掉电之后检测的电压的波动来判断电磁炉是否处于掉电状态。但是，如果电网电压的波动较大例如20V也会出现控制器404判断为电磁炉处于掉电状态的情况，为了避免因电网的电压波动控制器404误判断电磁炉为掉电状态，在本发明的一个实施例中，控制器404在连续预设次数地判断电磁炉的电压在预设时间内的波动处于第一预设电压范围内时，判断电磁炉处于掉电状态。具体地，其中，预设时间可以为0.01～0.8秒，第一预设电压范围为5～30V，即言，控制器404判断电磁炉的电压在预设时间例如0.01～0.8秒内的电压波动是否在第二预设电压范围例如5～30V内，并且，1次或者重复多次例如3次进行判断，如果控制器404经过多次例如3次判断电磁炉的电压在0.01～0.8秒内的波动处于5～30V内，则判断电磁炉处于掉电状态，进而控制器404发出控制信号至风机控制电路403以控制电磁炉的风机402启动以使电磁炉进行放电，并在电压检测电路401检测到电磁炉的电压在预设时间内的波动未达到第一预设电压范围时，控制器404控制风机关闭。否则，即控制器404经过1次或者多次例如3次判断，但是，不是每次电磁炉的电压在0.01～0.8秒内的波动均处于5～30V内，则控制器404判断电磁炉的电压波动为电网波动引起的。优选地，控制器404可以判断电磁炉在0.3秒内的电压波动是否大于10V，并且，重复多次例如3次进行判断，如果控制器404经过3次判断并且每次电磁炉在0.3秒内的电压波动均大于10V，则控制器404控制电磁炉的风机402启动以使电磁炉进行放电，并在电压检测电路401检测到电磁炉的电压在预设时间内波动未达到第一预设电压范围时，控制风机402关闭。否则，即控制器404经过1次或者多次例如3次判断但是不是每次例如其中有一次电磁炉在0.3秒内的电压波动小于10V，则控制器404判断电磁炉的电压波动为电网波动引起的。In a specific embodiment of the present invention, when the induction cooker is disconnected from the power grid, it can be detected that the voltage attenuation fluctuation range of the induction cooker is 4..6V-1.8V, so it can be judged whether the induction cooker is in the power down state. When the controller 404 judges that the induction cooker is in a power-off state, it sends a control signal to the fan control circuit 403 to control the start of the fan 402 of the induction cooker, so that the fan 402 consumes the residual power in the circuit board after the induction cooker is powered off. After the induction cooker is powered off, the voltage of the induction cooker detected by the voltage detection circuit 401 will fluctuate attenuation, and the controller 404 can determine whether the induction cooker is in a power-off state according to the detected voltage fluctuation after the induction cooker is powered off. However, if the fluctuation of the grid voltage is large such as 20V, the controller 404 also judges that the induction cooker is in a power-off state. In an embodiment, the controller 404 judges that the induction cooker is in a power-off state when the controller 404 determines that the fluctuation of the voltage of the induction cooker within a preset time is within a first preset voltage range for a preset number of times. Specifically, the preset time may be 0.01 to 0.8 seconds, and the first preset voltage range is 5 to 30V, that is, the controller 404 judges whether the voltage fluctuation of the induction cooker is Within the second preset voltage range, such as 5-30V, and judge once or multiple times, such as three times, if the controller 404 judges that the voltage fluctuation of the induction cooker within 0.01-0.8 seconds is within 0.01-0.8 seconds after multiple times, such as three times 5-30V, it is judged that the induction cooker is in a power-off state, and then the controller 404 sends a control signal to the fan control circuit 403 to control the start of the fan 402 of the induction cooker to discharge the induction cooker, and the voltage detection circuit 401 detects that the voltage of the induction cooker is within When the fluctuation within the preset time does not reach the first preset voltage range, the controller 404 controls the fan to turn off. Otherwise, that is, the controller 404 judges once or more times, for example, three times, but not every fluctuation of the voltage of the induction cooker within 0.01 to 0.8 seconds is within 5 to 30V, then the controller 404 judges that the voltage fluctuation of the induction cooker is caused by grid fluctuations. Preferably, the controller 404 can judge whether the voltage fluctuation of the induction cooker is greater than 10V within 0.3 seconds, and repeat the judgment multiple times, for example, 3 times, if the controller 404 judges three times and the voltage fluctuation of the induction cooker within 0.3 seconds each time are greater than 10V, then the controller 404 controls the fan 402 of the induction cooker to start to discharge the induction cooker, and when the voltage detection circuit 401 detects that the voltage of the induction cooker fluctuates within a preset time and does not reach the first preset voltage range, the fan 402 is controlled. closure. Otherwise, that is, the controller 404 judges once or more times, such as 3 times, but not every time, such as one of which, the voltage fluctuation of the induction cooker within 0.3 seconds is less than 10V, then the controller 404 judges that the voltage fluctuation of the induction cooker is caused by the grid fluctuation.
但是，在电磁炉处于待机状态时，如果电网电压出现较大波动例如电网电压波动在20V，而经过控制器404多次例如3次判断，电压检测电路401检测到的电压波动范围仍然满足掉电状态的条件例如电压波动范围大于10V，则控制器404会误判断为电磁炉处于掉电状态，因而控制电磁炉的风机402启动。为了避免控制器404误判断电磁炉处于掉电状态而使风机402长时间启动，在本发明的一个实施例中，在风机402启动之后，在电压检测电路401检测到电磁炉的电压在预设时间内波动未达到第一预设电压范围时，在检测到的电压稳定后，控制器404发出控制信号至风机控制电路403以控制风机402关闭。However, when the induction cooker is in the standby state, if the grid voltage fluctuates greatly, for example, the grid voltage fluctuates at 20V, and the controller 404 judges for many times, such as 3 times, the voltage fluctuation range detected by the voltage detection circuit 401 still meets the power-off state. For example, if the voltage fluctuation range is greater than 10V, the controller 404 will mistakenly judge that the induction cooker is in a power-off state, and thus control the fan 402 of the induction cooker to start. In order to prevent the controller 404 from misjudging that the induction cooker is in a power-off state and causing the fan 402 to start for a long time, in one embodiment of the present invention, after the fan 402 is started, the voltage detection circuit 401 detects that the voltage of the induction cooker is within a preset time When the fluctuation does not reach the first preset voltage range, after the detected voltage stabilizes, the controller 404 sends a control signal to the fan control circuit 403 to control the fan 402 to turn off.
在本发明的一个实施例中，如图4所示，上述电磁炉还可以包括整流电路405。整流电路405与市电、控制器404和风机402分别相连。整流电路405将交流电转化为直流电提供给电磁炉的风机402以使风机402正常工作。In an embodiment of the present invention, as shown in FIG. 4 , the above-mentioned induction cooker may further include a rectification circuit 405 . The rectifier circuit 405 is connected to the mains, the controller 404 and the fan 402 respectively. The rectifier circuit 405 converts the alternating current into direct current and supplies it to the fan 402 of the induction cooker so that the fan 402 can work normally.
综上所述，根据本发明实施例的电磁炉，在电磁炉处于掉电状态时，控制器发出控制信号至风机控制电路以控制风机启动，进而通过风机转动消耗掉电磁炉电路板储存的残余电量，从而实现电磁炉的快速放电，并且满足国家标准或欧洲标准对电磁炉掉电后放电的要求，并且不会增加电磁炉的待机功耗。此外，该电磁炉结构简单，不需要增加额外的电路，成本低。To sum up, according to the induction cooker of the embodiment of the present invention, when the induction cooker is in the power-off state, the controller sends a control signal to the fan control circuit to control the start of the fan, and then consumes the residual power stored in the circuit board of the induction cooker through the rotation of the fan, thereby Realize the rapid discharge of the induction cooker, and meet the requirements of the national standard or European standard for the discharge of the induction cooker after power failure, and will not increase the standby power consumption of the induction cooker. In addition, the induction cooker has a simple structure, does not need to add additional circuits, and has low cost.
