Description

Temperature controlled cooking device

The novel creation relates to a temperature control device, and in particular to a temperature control cooking device.

In general, electric cookers usually have an outer pot, an inner pot, and a temperature controller and heater mounted on the bottom of the outer pot. When the electric cooker is cooking, the heater continuously heats the water of the outer pot, whereby the food in the inner pot can be heated by water. At this point, the water in the inner and outer pots will continue to boil (ie, maintain at 100 ° C) until the water in the outer pot has completely evaporated. At this point, the temperature controller will stop the heater operation or adjust the heater to a holding state below 100 °C.

Since the general electric cooker cannot control the water temperature of the outer pot, the water temperature in the electric pot will be maintained at a high temperature of 100 ° C during cooking. That is to say, the general electric cooker is cooked at a high temperature throughout the cooking process. However, some ingredients are not suitable for cooking at a high temperature of 100 °C. Or, some ingredients must be cooked for a long time at temperatures below 100 °C to avoid destroying the nutrients of the ingredients or affecting the taste of the ingredients. In addition, some ingredients can show the true taste of the ingredients under long-term low-temperature cooking, and can also reduce the high temperature cooking. Produce substances that are harmful to the human body. However, the above cooking conditions are not achievable in a general electric cooker. Therefore, how to control the water temperature inside the electric cooker or to make the electric cooker have a low-temperature cooking function without changing the general electric cooker structure is one of the important subjects faced by those skilled in the art.

In view of this, the novel creation provides a temperature-controlled cooking device that can be used with an electric cooker to control the water temperature inside the electric cooker or to make the electric cooker have a low-temperature cooking function.

The temperature sensor is disposed inside the electric cooker to sense the water temperature inside the electric cooker, and accordingly generates a temperature sensing value. The power switch module is coupled between the power input end of the electric cooker and the external power source. The power switch module is controlled by a switching signal to transfer power provided by the external power source to the power input of the electric cooker. The controller is coupled between the temperature sensor and the power switch module to receive the temperature sensing value and the preset temperature value, and compare the temperature sensing value with the preset temperature value to generate the switching signal. When the controller determines that the temperature sensing value is greater than the preset temperature value, the controller disables the power switch module to stop the external power supply to supply power to the electric cooker, so that the water temperature inside the electric cooker is maintained at a preset temperature value.

In an embodiment of the present invention, when the controller determines that the temperature sensing value is less than the preset temperature value, the controller enables the power switch module to start the external power supply to supply power to the electric cooker, so that the inside of the electric cooker The water temperature is maintained at a preset temperature value.

In an embodiment of the present invention, when the controller enables the power switch module to start the external power supply to supply power to the electric cooker, the heater of the electric cooker starts to operate to increase the water temperature inside the electric cooker, so that The temperature sensing value rises.

In an embodiment of the present invention, the power switch module is further configured to set the preset temperature value.

In an embodiment of the present invention, the temperature sensor includes a thermocouple temperature sensor, a thermistor, or a semiconductor temperature sensor.

In an embodiment of the present invention, the power switch module includes a relay. The relay is coupled between the power input end of the electric pot and the external power source for controlling the switching signal to transmit the power provided by the external power source to the power input end of the electric pot.

In an embodiment of the novel creation, the relay is an electromechanical relay.

In an embodiment of the present invention, the power switch module further includes a temperature setting module. The temperature setting module is coupled to the controller for setting and providing a preset temperature value to the controller.

In an embodiment of the present invention, the temperature setting module has a plurality of temperature scale values, and the temperature setting module is provided to select one of the temperature scale values as a preset temperature value. .

In an embodiment of the present invention, the temperature setting module is further coupled to the relay to disable the relay to stop the external power supply to supply power to the electric cooker.

Based on the above, the novel temperature-controlled cooking device can be used in combination with a general electric cooker. When the electric kettle heats the water in the pot, the temperature-controlled cooking device can determine whether to transmit the electric power provided by the external power source to the electric pot by sensing the water temperature in the pot. In this way, the water temperature inside the electric cooker can be controlled to a preset temperature value. Moreover, by controlling the water temperature inside the electric cooker to a lower temperature value for cooking, the purpose of cooking at a low temperature and slow cooking can be achieved, and the original taste of the food material can be exhibited and the nutrient loss of the food material can be avoided.

2 is a schematic view of the temperature control cooking device of FIG. 1 used in conjunction with an electric cooker.

In order to make the content of the novel creation easier to understand, the following specific examples are examples in which the novel creation can be implemented. In addition, wherever possible, the same referenced elements/components/steps are used in the drawings and embodiments. The same or similar parts.

Please refer to FIG. 1 and FIG. 2 below. 1 is a block diagram of a temperature-controlled cooking device 100 in accordance with an embodiment of the present invention. 2 is a schematic view showing the use of the temperature-controlled cooking device 100 of FIG. 1 in conjunction with an electric cooker 200 (for example, a mechanical electric cooker, but is not limited thereto). The temperature-controlled cooking device 100 includes a temperature sensor 120, a power switch module 140, and a controller 160. The temperature sensor 120 may be disposed inside the electric kettle 200 to sense the water temperature inside the electric cooker 200, and accordingly generate the temperature sensing value TS. As shown in FIG. 2, the electric cooker 200 may have an outer pot 220, an inner pot 240, and a heater 230, but is not limited thereto. Therefore, the user can place the temperature sensor 120 in the water of the inner pot 240 of the electric cooker 200 (as shown in FIG. 2) to sense the water temperature of the inner pot 240, or the user can also set the temperature. The sensor 120 is placed in the water of the outer pot 220 of the electric cooker 200 to sense the water temperature of the outer pot 220, depending on the actual application and cooking requirements.

The power switch module 140 is coupled between the power input terminal 210 of the electric kettle 200 (for example, the power cord plug of the electric cooker 200) and the external power source 300 (for example, a socket capable of providing a commercial power). The power switch module 140 is controlled by the switch signal CS to transmit the power PWR provided by the external power source 300 to the power input terminal 210 of the electric kettle 200 to supply power to the electric cooker 200.

The controller 160 is coupled between the temperature sensor 120 and the power switch module 140 to receive the temperature sensing value TS and the preset temperature value DT. The controller 160 compares the temperature sensing value TS with the preset temperature value DT to generate the switching signal CS. When the controller 160 determines that the temperature sensing value TS is greater than the preset temperature value DT, the controller 160 disables the power switch module 140 to stop the external power source 300 from entering the electric kettle 200. Line power supply. At this time, since the heater 230 in the electric cooker 200 cannot be continuously heated to the water inside the electric cooker 200 due to the power failure, the water temperature inside the electric cooker 200 gradually decreases with time.

In contrast, when the controller 160 determines that the temperature sensing value TS is less than the preset temperature value DT, the controller 160 may enable the power switch module 140 to start the external power source 300 to supply power to the electric kettle 200. At this time, the heater 230 in the electric cooker 200 starts operating to warm the water inside the electric cooker 200, so that the temperature sensing value TS rises. Such a repeated cycle action maintains the temperature sensing value TS at the preset temperature value DT. That is, the temperature-controlled cooking device 100 can maintain the water temperature inside the electric cooker 200 at a preset temperature value DT.

In general, when the user wants to cook the food at a lower temperature (100 ° C lower than the boiling point of water, for example, 70 ° C, but not limited to this) and for a long time, the user only needs to set the temperature. The sensor 120 is placed in the water of the outer pot 220 or the inner pot 240 of the electric cooker 200 to sense the water temperature, and the required temperature is set through the power switch module 140 (ie, the preset temperature value DT, for example, 70 ° C ). In this way, during the entire cooking process, the temperature sensing value TS (ie, the water temperature inside the electric cooker 200) sensed by the controller 160 through the temperature sensor 120 is higher than the preset temperature value DT (for example, 70). At ° C), the controller 160 can turn off the power switch module 140 through the switch signal CS to stop the external power source 300 from supplying power to the electric cooker 200. When the controller 160 senses the temperature sensing value TS sensed by the temperature sensor 120 (ie, the water temperature inside the electric cooker 200) is lower than the preset temperature value DT (for example, 70 ° C), the controller 160 can pass the switch. The signal CS is used to turn on the power switch module 140 to start the external power source 300 to supply the electric cooker 200. Electric, so that the heater 230 in the electric cooker 200 heats the water inside the electric cooker 200. In this way, the water temperature inside the electric cooker 200 can be controlled and maintained at a preset temperature value DT (for example, 70 ° C), so as to achieve the purpose of cooking at a low temperature and slow cooking, and the taste of the food can be exhibited and the nutrient loss of the food can be avoided. .

It is worth mentioning that during the entire cooking process, the user can reset the required temperature (ie, the preset temperature value DT) through the power switch module 140 at any time according to the needs of cooking. When the preset temperature value DT is changed (for example, from 70 ° C to 50 ° C, but is not limited thereto), the controller 160 may turn the power switch on or off according to the reset preset temperature value DT (ie, 50 ° C). The module 140 is configured to maintain the water temperature inside the electric cooker 200 at a preset temperature value DT (ie, 50 ° C) after resetting.

In an embodiment of the present invention, the power switch module 140 can also be used to set a preset temperature value DT, but the novel creation is not limited thereto.

In an embodiment of the present novel creation, the temperature sensor 120 may include a thermocouple temperature sensor, a thermistor, or a semiconductor temperature sensor, but the novel creation is not limited thereto.

In an embodiment of the present novel creation, the power switch module 140 may include a relay 142, but the novel creation is not limited thereto. The relay 140 is configured to be controlled by the switching signal CS to transmit the power PWR provided by the external power source 300 to the power input terminal 210 of the electric kettle 200 to supply power to the electric kettle 200. In an embodiment of the present invention, the relay 142 may be an electromechanical relay (EMR), but the novel creation is not limited thereto.

In an embodiment of the present invention, the power switch module 140 can also be packaged. The temperature setting module 144 is included, but the novel creation is not limited to this. The temperature setting module 144 is coupled to the controller 160 and can be used to set and provide a preset temperature value DT to the controller 160. In an embodiment of the present invention, the temperature setting module 144 can be implemented by using a turntable. The temperature setting module 144 can have a plurality of temperature scale values 145. The temperature setting module 144 can be used to select one of the temperature scale values 145 as the preset temperature value DT. For example, the temperature scale value 145 may include 30 ° C, 50 ° C, 70 ° C, 90 ° C, etc., when the arrow indicator 146 of the temperature setting module 144 is selected to the temperature scale value 145 shown at 70 ° C, represents the pre- Let the temperature value DT be set to 70 °C.

In another embodiment of the present invention, the temperature setting module 144 is further coupled to the relay 142, and can be used to disable the relay 142 to stop the external power source 300 from supplying power to the electric battery 200. For example, the temperature setting module 144 can include a scale position representative of OFF (OFF). When the arrow indicator 146 of the temperature setting module 144 is selected to a scale position representing OFF (OFF), the relay 142 will be turned off. The external power source 300 is stopped to supply power to the electric cooker 200.

In the above embodiment of the novel creation, the controller 160 can be implemented using a comparator, a micro-processor, an special function integrated circuit (ASIC), or a programmable logic gate array (FPGA). However, this new creation is not limited to this. In addition, in other embodiments of the novel creation, the controller 160 can also be integrated with the power switch module 140 into a single module.

On the other hand, in an embodiment of the present invention, the mechanism design of the lid (not shown) of the electric cooker 200 can be changed so that when the electric cooker 200 is covered with the lid, The temperature sensor 120 of the temperature-controlled cooking device 100 can be smoothly placed into the water inside the electric kettle 200 (for example, the outer pot 220 or the water in the inner pot 240), but is not limited thereto.

In an embodiment of the present novel creation, a control method of the temperature-controlled cooking apparatus 100 is proposed. First, the temperature sensor 120 is disposed inside the electric kettle 200 to sense the water temperature inside the electric cooker 200 and accordingly generate the temperature sensing value TS. Next, the power switch module 140 is coupled between the power input terminal 210 of the electric kettle 200 and the external power source 300 to transmit the power provided by the external power source 300 to the power input terminal 210 of the electric kettle 200 to the electric cooker 200. The power is supplied, and the preset temperature value DT is set through the power switch module 140. Then, it is determined whether the temperature sensing value TS is greater than the preset temperature value DT. If the determination result is yes, the power switch module 140 is disabled to stop the external power source 300 to supply power to the electric cooker 200; if the judgment result is no, The power switch module 140 can supply power to the electric cooker 200 by starting the external power source 300. In this way, the water temperature inside the electric cooker 200 can be maintained at the preset temperature value DT.

In summary, the temperature-controlled cooking device of the novel creation embodiment can be used in combination with a general electric cooker. When the electric kettle heats the water in the pot, the temperature-controlled cooking device can determine whether to transmit the electric power provided by the external power source to the electric pot by sensing the water temperature in the pot. In this way, the water temperature inside the electric cooker can be controlled to a preset temperature value. Moreover, by controlling the temperature of the water inside the electric cooker to a lower temperature value for cooking, the purpose of cooking at a low temperature and slow cooking can be achieved, and the original taste of the food can be exhibited and the loss of nutrients of the food can be avoided.
