Electric pot expansion device

The present invention relates to an expansion device, and more particularly to an expansion device for an electric cooker.

The electric cooker can be said to be an essential electrical appliance for every household. In general, when cooking ingredients in an electric cooker, people are accustomed to continue to use the electric cooker to simmer the ingredients for 5 to 10 minutes after the power switch of the electric cooker jumps, so that the taste of the ingredients is more delicious. However, the conventional electric cooker does not have the function of prompting or timing, so the user often can only judge the burning time after the cooking of the electric cooker is completed, thereby causing inconvenience in the use of the electric cooker. Even sometimes, human negligence can cause the ingredients to burn for too long or too short, which in turn reduces the taste and taste of the ingredients. In addition, some ingredients (for example, green vegetables) should not be cooked for too long. However, when the power switch of the electric cooker is pressed to start heating, the user often cannot accurately judge the cooking time of the electric cooker, which may cause overcooking and affect the taste of the food.

The novel creation provides an expansion device for determining whether to start a counting program according to the movement of the magnetic component on the electric cooker, and generating a prompt signal at the end of the counting process. Thereby, the user can control the cooking time of the electric cooker and the simmering time after the cooking of the electric cooker, thereby improving the convenience of use of the electric cooker.

The expansion device of the present invention is applicable to an electric cooker and includes a casing, a magnetic induction element and a control circuit. The housing is adapted to be disposed on the pot of the electric kettle, and the side wall of the housing is adjacent to the first position of the switch plate on the pot. The magnetic sensing element is disposed within the housing adjacent to a sidewall of the housing. The magnetic component of the electric pan moves between a first position and a second position of the switchboard, and the magnetic sensing element generates a detection signal in response to movement of the magnetic component. The control circuit is electrically connected to the magnetic sensing component, and determines whether to start the counting process according to the detection signal. In addition, when the counting process ends, the expansion device generates a prompt signal.

In an embodiment of the present invention, when the magnetic component moves from the first position to the second position, the magnetic sensing element switches the detection signal from the first level to the second level. In the first mode, the control circuit initiates the counting process in response to the detection signal being switched from the first level to the second level.

In an embodiment of the present invention, when the magnetic component moves from the second position to the first position, the magnetic sensing element switches the detection signal from the second level to the first level. In the second mode, the control circuit initiates the counting process in response to the detection signal being switched from the second level to the first level.

Based on the above, the magnetic sensing element in the expansion device of the present invention can generate a detection signal in response to the movement of the magnetic component on the electric cooker, and the control circuit in the expansion device can decide whether to start the counting process according to the detection signal. Thereby, the user can control the cooking time of the electric cooker and the simmering time after the cooking of the electric cooker, thereby improving the convenience of use of the electric cooker.

The above described features and advantages of the present invention will become more apparent and understood from the following description.

1 is a schematic view showing the arrangement of an expansion device on an electric cooker according to an embodiment of the present invention. As shown in FIG. 1, the expansion device 100 is applied to the electric cooker 101. The electric cooker 101 includes a lid 102 and a pot body 103. In addition, the pot body 103 is provided with a switch board 104, and the magnetic component 105 exposed by the switch board 104 is connected to the power switch of the electric pot 101. Specifically, one end of the power switch of the electric cooker 101 is provided with a magnetic component 105, and the user can press the magnetic component 105 to drive the switching of the power switch. Further, the magnetic component 105 is magnetic, that is, the magnetic component 105 includes a portion composed of a magnetic material. For example, in one embodiment, the magnetic assembly 105 includes a pressing portion for engaging a power switch and a magnetic kit, and the magnetic kit can be sleeved on a surface of the pressing portion.

The expansion device 100 includes a housing 110 and a magnetic sensing element 120. The housing 110 is adapted to be disposed on the pot body 103 of the electric cooker 101, and the side wall 111 of the housing 110 is adjacent to the first position A11 of the switch board 104 on the pot body 103. The magnetic sensing element 120 is disposed within the housing 110 and adjacent to the sidewall 111 of the housing 110. In other words, in an overall configuration, the magnetic sensing element 120 can be adjacent to the first position A11 of the switchboard 104. In addition, the magnetic component 105 of the electric cooker 101 can be moved between the first position A11 and the second position A12 of the switch board 104, and can be moved away from or close to the magnetic sensing element 120 in the expansion device 100. In contrast, the magnetic sensing element 120 will generate detection signals having different levels in response to the remote or proximity of the magnetic component 105.

It is worth mentioning that the movement of the magnetic component 105 of the electric cooker 101 is related to the start and end of the heat treatment of the electric cooker 101. Therefore, the expansion device 100 can discriminate the cooking state of the electric cooker 101 through the detection signal generated by the magnetic induction element 120, so as to timely remind the user that the cooking time or the sizzling time of the electric cooker 101 has reached the required pre-heating time. Set the time. For example, in one embodiment, the magnetic sensing element 120 can generate a detection signal in response to movement of the magnetic component 105. In addition, the control circuit in the expansion device 100 can determine whether to start a counting process according to the detection signal. Moreover, when the counting process ends, the expansion device 100 can generate a prompt signal to prompt the user.

2 is a circuit diagram of an expansion device in accordance with an embodiment of the present invention, and the operation of the expansion device 100 will be further described below with reference to FIGS. 1 and 2. As shown in FIG. 2, the expansion device 100 further includes a resistor R2, a control circuit 210, an input interface 220, a display panel 230, and a sound generator 240. For convenience of description, FIG. 2 further illustrates that the magnetic induction can be moved away from or close to the magnetic induction. Magnetic component 105 of component 120.

Specifically, the magnetic induction element 120 may be constituted by a reed switch SW2. The first end of the resistor R2 receives the reference voltage V2, and the second end of the resistor R2 is electrically connected to the first end of the reed switch SW2 and the control circuit 210. The first end of the reed switch SW2 generates a detection signal S21, and the second end of the reed switch SW2 is electrically connected to the ground. In addition, the input interface 220, the display panel 230, and the sound generator 240 are electrically connected to the control circuit 210.

In operation, the expansion device 100 includes a first mode, and the user can control the cooking time of the electric cooker 101 through the expansion device 100 located in the first mode. For example, in the first mode, when the user presses the magnetic component 105 to initiate the heat treatment of the electric cooker 101, that is, when the magnetic component 105 moves along the arrow symbol 201 from the first position A11 to the second position. At A12, the magnetic sensing component 120 switches the detection signal S21 from the first level to the second level. For example, when the magnetic component 105 is in the first position A11, the magnetic sensing element 120 (eg, the reed switch SW2) will be turned on in response to the proximity of the magnetic component 105, thereby causing the level of the detection signal S21 to be pulled down to low. Level (ie, the first level). On the other hand, when the magnetic component 105 is in the second position A12, the magnetic sensing element 120 (for example, the reed switch SW2) will be incapable of being turned on in response to the magnetic component 105, thereby causing the level of the detection signal S21 to be Pull up to the high level (ie, the second level).

In addition, in the first mode, the control circuit 210 starts the counting process in response to the detection signal S21 being switched from the first level to the second level. When the counting procedure is initiated, control circuit 210 will begin counting for a predetermined time (eg, 30 minutes). When the preset time is counted, the control circuit 210 will end the counting process, thereby causing the expansion device 100 to generate a prompt signal. For example, when the counting process ends, the control circuit 210 can drive the sound generator 240. Thereby, the sound generator 240 can play a prompt sound, thereby reminding the user that the cooking time of the electric cooker 101 has reached the preset time. In an embodiment, the sound generator 240 can be, for example, a buzzer.

In other words, in the first mode, when the user presses the magnetic component 105 to activate the electric cooker 101, the expansion device 100 will correspondingly start the counting process, and the expansion device 100 can issue a prompt signal at the end of the counting process to remind the use. The heat treatment of the electric cooker 101 can be directly turned off. In this way, the user can accurately control the cooking time of the electric cooker 101, thereby helping to improve the convenience of the electric cooker 101 in use, and avoiding overcooking of the foodstuff in the electric cooker 101. In addition, during the execution of the counting process, the display panel 230 can also be used to display counting information of a preset time, for example, counting up information or counting down information. That is, the expansion device 100 can remind the user of the cooking state of the electric cooker 101 by means of a positive/countdown time.

Further, the expansion device 100 further includes a second mode, and the user can control the sizzling time after the cooking of the electric cooker 101 is completed by the expansion device 100 located in the second mode. For example, in the second mode, the expansion device 100 does not turn on the counting process in response to the activation of the electric cooker 101, but turns on the counting process when the heating process of the electric cooker 101 is completed.

Specifically, when the heating process of the electric cooker 101 is completed, the power switch of the electric cooker 101 will automatically bounce, thereby causing the magnetic component 105 engaged with the power switch to move from the second position A12 to the first position along the arrow symbol 202. A11. At this time, the magnetic sensing element 120 will switch the detection signal S21 from the second level (eg, high level) to the first level (eg, low level) in response to the movement of the magnetic component 105. In addition, in the second mode, the control circuit 210 starts the counting process in response to the detection signal S21 being switched from the second level to the first level. In addition, when the counting program is started, the control circuit 210 will start counting for a preset time (for example, 10 minutes), and can display the counting information of the preset time through the display panel 230. On the other hand, when the preset time is counted, the control circuit 210 will end the counting process, thereby causing the expansion device 100 to generate a prompt signal, such as a prompt sound played by the sound generator 240.

In other words, in the second mode, when the heating process of the electric cooker 101 ends, the expansion device 100 will correspondingly start the counting process, and the expansion device 100 can issue a prompt signal at the end of the counting process to remind the user that the electric cooker 101 is inside. The ingredients have been cooked, so the user can open the lid 102 of the electric cooker 101. In this way, the user will be able to accurately control the burning time after the cooking of the electric cooker 101 is completed, thereby contributing to the convenience in use of the electric cooker 101. In other words, through the arrangement of the expansion device 100, the user can more conveniently use the electric cooker 101 to cook delicious dishes, thereby eliminating the need to spend more money to purchase the electronic pan.

It is worth mentioning that a plurality of reference times are provided in the control circuit 210, and the control circuit 210 can select different reference times in response to different modes to set the preset time, thereby causing the expansion device 100 to have different modes in different modes. The preset time. For example, the preset time in the first mode may be set to 30 minutes, and the preset time in the second mode may be set to 10 minutes. In addition, the user can also set the preset time in each mode through the input interface 210.

For example, the input interface 210 can include a plurality of buttons disposed on the housing 110, such as the button 130 of FIG. The user can input the first information through the input interface 210 (eg, a button on the housing 110). In contrast, control circuit 210 can adjust the preset time in each mode in response to the first information from input interface 210. In addition, the user can also input the second information through the input interface 210, and the control circuit 210 can also switch the expansion device 100 to the first mode or the second mode in response to the second information.

In summary, the magnetic sensing element in the expansion device of the present invention can generate a detection signal in response to the movement of the magnetic component on the electric cooker. In addition, the control circuit in the expansion device can analyze the change of the level of the detection signal, and can decide whether to start the counting process according to the analysis result. Thereby, the user can control the cooking time of the electric cooker and the simmering time after the cooking of the electric cooker, thereby improving the convenience of use of the electric cooker.
