As the application of these appliances increases, safety has gradually become a major concern, especially for children, as accidental contact with these appliances can easily lead to accidents. Therefore, more and more electrical appliances are being equipped with child lock buttons to prevent children from accidentally pressing switches and controlling various appliances. However, currently, once a child lock function is set, it needs to be deactivated when changing the settings. Setting the settings again to prevent children from operating the appliances is cumbersome and requires repeated operations.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0051] It should be noted that the terms "first," "second," etc., in the specification and accompanying drawings of this invention are used to distinguish similar users and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0052] The following is a detailed description of embodiments of the child lock status control method for electrical appliances described in this invention. Figure 1 The diagram shown is a flowchart illustrating the child lock status control method for electrical appliances provided by the present invention. The specific implementation process includes the following steps:

[0053] Step 101: With the electrical device in a locked state, detect the contact signal on the surface of the child lock button on the electrical device, and determine the area parameter of the equivalent electrode corresponding to the contact signal and the distance parameter between the equivalent electrode and the preset electrode in the child lock button. The preset electrode includes an internal emitting electrode and a receiving electrode, and a capacitor is formed between the internal emitting electrode and the receiving electrode.

[0054] The electrical appliances mentioned include, but are not limited to, air conditioners, water heaters, televisions, microwave ovens, etc., without specific limitations. The child lock button can be a capacitor structure formed by sending and receiving electrodes on a PCB (Printed Circuit Board), with a shell layer on top. A pre-defined gap (e.g., 3mm) exists between the lower surface of this shell layer and the sending and receiving electrodes. When a user's finger or other part contacts the shell layer, a certain contact area is created, causing the shell layer to shift and deform downwards. This changes the distance parameter between the equivalent electrode generated by the finger or other part and the electrode inside the child lock button (e.g., to 2mm). Furthermore, since the finger or other part is also a charged body, equivalent to an equivalent electrode, when the finger or other part presses on the shell layer, it affects the charge on the receiving and sending electrodes, thus affecting the capacitance value between the two electrodes. The child lock button can be installed on the electrical appliance or replace the switch button of the electrical appliance. The specific structure of the child lock button is as follows: Figure 2 and 3 As shown, the two images above are schematics of the touch principle when there is no movement. The sensor measures the capacitance C between the two electrodes when there is no human touch. One electrode is the receiving electrode, and the other electrode is the transmitting electrode.

[0055] In the specific implementation of this step, when the electrical device is in a locked state, a sensor preset within the child lock button detects the contact signal on the surface of the child lock button on the electrical device. Based on the corresponding sensor, the area parameter of the equivalent electrode corresponding to the contact signal and the distance parameter between the equivalent electrode and the preset electrode in the child lock button are obtained. The sensor includes, but is not limited to, pressure sensors and displacement sensors. Specifically, the process of obtaining the area parameter of the equivalent electrode corresponding to the contact signal based on the corresponding sensor includes: obtaining the contact area between the object corresponding to the contact signal and the surface of the child lock button based on the corresponding sensor; and determining the area parameter of the equivalent electrode corresponding to the contact signal based on the contact area.

[0056] Step 102: Based on the area parameter of the equivalent electrode and the distance parameter between the equivalent electrode and the preset electrode in the child lock button, determine the capacitance value between the transmitting electrode and the receiving electrode inside the child lock button; control the operating state of the electrical device according to the capacitance value.

[0057] In this specific implementation step, the area parameter of the equivalent electrode and the distance parameter between the equivalent electrode and the preset electrode in the child lock button can be input into a preset capacitance value algorithm model to obtain the capacitance value between the transmitting electrode and the receiving electrode inside the child lock button. The area parameter of the equivalent electrode is directly proportional to the capacitance value, and the distance parameter between the equivalent electrode and the preset electrode in the child lock button is inversely proportional to the capacitance value. Based on the capacitance value, the actual charge amount between the transmitting electrode and the receiving electrode is determined. The capacitance value is directly proportional to the actual charge amount. The actual charge amount is compared with a preset charge amount threshold to obtain a comparison result, and the operating state of the electrical device is controlled based on the comparison result. The process of comparing the actual charge amount with a preset charge threshold to obtain a comparison result, and controlling the operating state of the electrical device based on the comparison result, specifically includes: comparing the actual charge amount with the preset charge threshold; if the actual charge amount is greater than or equal to the charge threshold, determining that the object generating the contact signal meets a preset age condition, and controlling the electrical device to enter the on state; or, if the actual charge amount is less than the charge threshold, determining that the object generating the contact signal does not meet the preset age condition, and controlling the electrical device to remain in the locked state. In addition, the process of determining the actual charge amount between the transmitting electrode and the receiving electrode based on the capacitance value includes: obtaining the voltage value corresponding to the current capacitance value; and calculating the actual charge amount between the transmitting electrode and the receiving electrode based on the capacitance value and the voltage value. For example, charge Q = the product of voltage U and capacitance C.

[0058] The following examples illustrate this point. Figure 6 As shown, the touch-based mechanism detects whether a finger or other body part is touching the child lock button, and whether a two-way valve is touching the button, by measuring the change in charge on the transmitting electrode. Since these parts (equivalent to a motor) are also charged, when a finger or other body part presses on the outer casing surface, it affects the charge on the receiving and transmitting electrodes, thus affecting the capacitance C (Cm0) between the two electrodes. The capacitance calculation algorithm is as follows:

[0059]

[0060] In the formula: e0 and er are the dielectric constants of air and PCB board, respectively; S is the area parameter of the equivalent electrode generated by the fingers and other parts (the effective contact area of ​​the fingers and other parts); D is the distance parameter between the equivalent electrode and the preset electrode.

[0061] It should be noted that because adult and child fingers are different in size, the equivalent electrode area differs, affecting the value of S in the formula. Furthermore, the different pressure applied by children and adults when pressing buttons affects D, thus influencing the value of C. The different changes in C caused by child and adult touches result in different changes in charge on the transmitting electrode, providing a basis for distinguishing between adult and child touches in child lock mode. Therefore, when processing electrical signals in child lock mode, the preset charge threshold for touch is adjusted so that adult touches can be recognized, while child touches are blocked from receiving the contact signal. Figure 4 and 5 As shown, C = Cm for adults and C = Cm1 for children.

[0062] This invention addresses the fundamental principles of touchscreen operation, identifying differences between children and adults. When an electronic device is equipped with a child lock, the software automatically adjusts preset parameters such as charge thresholds to distinguish between adult and child touches. This allows adults to operate the device even with the child lock active. In other words, after setting the child lock function, the device adjusts its sensitivity and button trigger charge thresholds to differentiate between adults and children, ensuring that adult operation is possible while child operation is disabled. Therefore, adults can change settings without unlocking the child lock after setting the child lock.

[0063] The present invention provides a child lock status control method for electrical appliances. When the electrical appliance is locked, it detects the contact signal on the surface of the child lock button on the appliance, determines the area parameter of the equivalent electrode corresponding to the contact signal and the distance parameter between the equivalent electrode and a preset electrode in the child lock button, and determines the capacitance value between the transmitting electrode and the receiving electrode inside the child lock button based on the area parameter of the equivalent electrode and the distance parameter between the equivalent electrode and the preset electrode in the child lock button. The operating state of the electrical appliance is then controlled according to the capacitance value. This method makes the electrical appliance less prone to accidental operation, effectively improves the accuracy and efficiency of the child lock button in object recognition, and enhances the user experience.
