Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, for example, it relates to a control panel, an electrical equipment, and a dew condensation detection method for the control panel. Background Art

[0002] Some intelligent electrical equipment (such as a refrigerator) usually has a control panel. The control panel has a control surface for interacting with users. The control panel can generate corresponding information in response to the operations of users on the control surface.

[0003] However, as the air humidity around the control panel gradually increases or the situation of heat and cold transformation intensifies, dew condensation will gradually appear on the control surface. Dew condensation can cause the control logic of the control panel to be chaotic, which in turn leads to the malfunction of the electrical equipment, and even causes serious problems such as short - circuit fire of the circuit. Therefore, it is very important to detect the dew condensation situation of the control surface of the control panel in a timely manner.

The attached drawings are for reference and illustration purposes only, and are not used to limit the embodiments of the present disclosure.

[0057] It should be noted that, without conflict, the embodiments in this disclosure and the features in the embodiments may be combined with each other.

[0058] Some intelligent electrical appliances (such as refrigerators) usually have a control panel. The control panel has a manipulation surface for interacting with users. The control panel can generate corresponding information in response to the operations of users on the manipulation surface.

[0059] However, as the air humidity around the control panel gradually increases or the situation of heat and cold transformation intensifies, condensation will gradually occur on the manipulation surface. Condensation will cause the control logic of the control panel to be chaotic, which will further lead to the malfunction of the electrical appliance, and even cause serious problems such as short - circuit fire of the circuit. Therefore, it is very important to detect the condensation situation of the manipulation surface of the control panel in a timely manner.

[0060] In the related art, a humidity sensor can be installed on the control panel to detect the condensation situation of the manipulation surface of the control panel. However, the cost of installing a humidity sensor on the control panel is relatively high, and it will make the structure of the control panel too complex.

[0061] Combined with Figure 1 As shown, this disclosure embodiment provides a control panel 10. The control panel 10 includes a panel body 1, a control unit 2, a first electrode 3, a second electrode 4, and a current output part (not shown in the figure).

[0062] The panel body 1 includes a manipulation surface 11. The manipulation surface 11 is used to face users. Specifically, when the control panel 10 is installed on the electrical appliance 300, the manipulation surface 11 faces outward so that users can touch it. The manipulation surface 11 is used to interact with users. Users can perform corresponding operations on the manipulation surface 11. For example, users can perform corresponding operations on the manipulation surface 11 by touching. The control panel 10 can generate corresponding information in response to the operations of users on the manipulation surface 11, so as to control the electrical appliance 300.

[0063] Optionally, the control unit 2 is a device with data (information) processing functions, such as Figure 5 and Figure 7 As shown, the control unit 2 can be a micro - control unit 2 (Micro Control Unit, MCU). The control unit 2 can also be a device such as a Field Programmable Gate Array (FPGA), an Advanced RISC Machine (ARM) processor, etc.

[0064] Optionally, the panel body 1 and the control unit 2 can be separately arranged.

[0065] Optionally, the control unit 2 can be integrated into the panel body 1.

[0066] Optionally, the panel body 1 is provided with a controller having a data (information) processing function by itself, and this controller is different from the control unit 2.

[0067] Optionally, the control unit 2 is the controller of the panel body 1 itself having a data (information) processing function.

[0068] In the embodiment of the present disclosure, the current output unit can output current to the first electrode. Among them, Figure 5 and Figure 7 VDD in represents the current output unit.

[0069] Optionally, the current output unit is a power supply that can output.

[0070] Optionally, the current output unit is a component connected to the power supply. The power supply outputs current to the first electrode 3 through the current output unit. Among them, the power supply connected to the current output unit can be the power supply of the control panel 10 itself, and the power supply connected to the current output unit can also be the power supply of the electrical equipment 30 to which the control panel 10 belongs.

[0071] Optionally, as Figure 5 and Figure 7 shown, the control panel 10 further includes a resistive device R1, and the current output unit is connected to the first electrode 3 through the resistive device R1.

[0072] The first electrode 3 and the second electrode 4 are arranged at intervals and are respectively electrically connected to the control unit 2. The first electrode 3 and the second electrode 4 are both at least partially arranged on the manipulation surface 11. The current output unit is electrically connected to the first electrode 3, and the current output unit can output a cut-off current to the first electrode 3, so that the first electrode 3 outputs current to the control unit 2.

[0073] For the convenience of understanding and expression, the embodiment of the present disclosure defines the current output by the first electrode 3 to the control unit 2 as the output current of the first electrode 3. Since the first electrode 3 and the second electrode 4 are arranged at intervals, when the manipulation surface 11 of the panel body 1 is not dew condensation, the resistance between the first electrode 3 and the second electrode 4 is very large and can be regarded as being in an insulating state. At this time, the current value of the output current of the first electrode 3 is large.

[0074] As the humidity of the air around the control panel 10 gradually increases or the situation of heat and cold transformation intensifies, dew condensation will gradually occur on the control surface 11 of the panel body 1. The resistance between the first electrode 3 and the second electrode 4 will gradually decrease, forming a current path with a gradually decreasing resistance between the first electrode 3 and the second electrode 4. Therefore, the current output by the current output unit also begins to gradually shunt to the second electrode 4, which causes the current value of the output current of the first electrode 3 to gradually become smaller. That is to say, as the dew condensation on the control surface 11 of the panel body 1 intensifies, the current value of the output current of the first electrode 3 will gradually become smaller.

[0075] The control unit 2 can obtain the current value of the output current of the first electrode 3. As described above, as the dew condensation on the control surface 11 of the panel body 1 intensifies, the current value of the output current of the first electrode 3 will gradually become smaller. Based on this principle, an embodiment of the present disclosure can preset a current threshold. In the embodiment of the present disclosure, the current threshold can be determined according to actual design requirements. Generally speaking, when the current value of the output current of the first electrode 3 is equal to the current threshold, it should be ensured that the dew condensation on the control surface 11 of the panel body 1 does not affect the normal operation of the control panel 10. For example, the current threshold can be 0.5 mA.

[0076] The control unit 2 is configured to: obtain the current value of the output current of the first electrode 3, and output a dew condensation alarm signal when it is determined that the current value is less than the current threshold. Specifically, the control unit 2 can periodically obtain the current value of the output current of the first electrode 3. Each time a current value of the output current of the first electrode 3 is obtained, the current value of the output current of the first electrode 3 can be compared with the current threshold. When it is determined that the current value of the output current of the first electrode 3 is less than the current threshold, a dew condensation alarm signal is output.

[0077] In the control panel 10 provided by the embodiment of the present disclosure, the dew condensation on the control surface 11 of the panel body 1 will cause the output current of the first electrode 3 to become smaller. By comparing the current value of the output current of the first electrode 3 with the current threshold, the control unit 2 can detect the dew condensation on the control surface 11. This dew condensation detection method only needs to add a control unit 2 and two electrodes in the control panel 10, which reduces the dew condensation detection cost of the control panel 10, and the control unit 2 and the electrodes are small in size and easy to arrange, which can keep the structure of the control panel 10 simple.

[0078] In some embodiments, the part of the first electrode 3 disposed on the control surface 11 of the panel body 1 and the part of the second electrode 4 disposed on the control surface 11 of the panel body 1 are arranged at intervals in the vertical direction.

[0079] In an embodiment of the present disclosure, the vertical direction is the direction of gravity at the position where the control panel 10 is located. Therefore, when dew condensation occurs on the control surface 11 of the panel body 1, water droplets may flow from top to bottom. In this case, the portion of the first electrode 3 disposed on the control surface 11 of the panel body 1 and the portion of the second electrode 4 disposed on the control surface 11 of the panel body 1 are spaced apart in the vertical direction, so that an electric current path with a smaller resistance is more likely to be formed between the first electrode 3 and the second electrode 4 due to the downward flow of water droplets, thereby making it easier for the output current of the first electrode 3 to become smaller, which helps the control unit 2 to detect the dew condensation on the control surface 11 earlier.

[0080] In some embodiments, the control unit 2 is configured to: obtain the current value of the output current of the first electrode 3, and output a dew condensation alarm signal when it is determined that the current value is less than the current threshold within a preset time period. Specifically, the control unit 2 can periodically obtain the current value of the output current of the first electrode 3. Each time a current value of the output current of the first electrode 3 is obtained, the current value of the output current of the first electrode 3 is compared with the current threshold. When it is determined that the current value of the output current of the first electrode 3 is less than the current threshold, a dew condensation alarm signal is output. Here, when the control unit 2 determines that the current value is less than the current threshold within a preset time period and then outputs a dew condensation alarm signal, it can ensure the accuracy and reliability of the detection result of the control unit 2 for the dew condensation situation.

[0081] In an embodiment of the present disclosure, the preset time period can be determined according to actual design requirements. For example, the preset time period can be 3 seconds, 5 seconds, etc.

[0082] In some embodiments, both the first electrode 3 and the second electrode 4 are wires. The portion of the first electrode 3 disposed on the control surface 11 of the panel body 1 and the portion of the second electrode 4 disposed on the control surface 11 of the panel body 1 are spaced apart in the vertical direction. Moreover, the portion of the first electrode 3 disposed on the control surface 11 of the panel body 1 and the portion of the second electrode 4 disposed on the control surface 11 of the panel body 1 are both parallel to the horizontal direction.

[0083] In an embodiment of the present disclosure, the vertical direction is the direction of gravity at the position where the control panel 10 is located, and the horizontal direction is perpendicular to the direction of gravity at the position where the control panel 10 is located. Since the first electrode 3 and the second electrode 4 in the form of wires are arranged in parallel in the horizontal direction, there are a large number of position points between them that can form a current path, which increases the possibility of forming a current path between the first electrode 3 and the second electrode 4, making it easier for the output current of the first electrode 3 to become smaller, thereby helping the control unit 2 to detect the condensation on the control surface 11 earlier. In addition, when condensation occurs on the control surface 11 of the panel body 1, water droplets may flow from top to bottom. In this case, the part of the first electrode 3 disposed on the control surface 11 of the panel body 1 and the part of the second electrode 4 disposed on the control surface 11 of the panel body 1 are arranged at intervals in the vertical direction, and a current path with a smaller resistance can be easily formed between the first electrode 3 and the second electrode 4 due to the water droplets flowing from top to bottom, making it easier for the output current of the first electrode 3 to become smaller, further increasing the possibility that the control unit 2 detects the condensation on the control surface 11 earlier.

[0084] In an embodiment of the present disclosure, the part of the first electrode 3 disposed on the control surface 11 of the panel body 1 and the part of the second electrode 4 disposed on the control surface 11 of the panel body 1 are close to the bottom of the panel body 1 in the vertical direction. There are fewer circuit elements and lower temperature at the bottom of the panel body 1, and the area close to the bottom of the panel body 1 is more likely to condense. By arranging at least a part of the first electrode 3 and the second electrode 4 in the area close to the bottom of the panel body 1, at the initial stage of condensation in other areas of the control surface 11, more condensation can occur faster in the area close to the bottom of the panel body 1, so that a current path can be formed between the first electrode 3 and the second electrode 4 more easily, making it easier for the output current of the first electrode 3 to become smaller, and helping the control unit 2 to detect the condensation on the control surface 11 earlier.

[0085] Moreover, the water droplets formed by condensation flow from top to bottom. By arranging at least a part of the first electrode 3 and the second electrode 4 in the area close to the bottom of the panel body 1, the flowing water droplets formed by condensation in most areas of the control surface 11 above the first electrode 3 and the second electrode 4 can pass through the area between the first electrode 3 and the second electrode 4, so that a current path with a smaller resistance can be easily formed between the first electrode 3 and the second electrode 4 for the control unit 2 to detect the condensation situation. This improves the detection result of the control unit 2 for the condensation situation to cover most areas of the control surface 11, and improves the reliability and accuracy of the detection result.

[0086] Combined with Figure 2 and Figure 3As shown, in some embodiments, the control surface 11 is provided with a control area 110 for interacting with the user. The user can perform corresponding operations in the control area 110. For example, the user can perform corresponding operations in the control area 110 by touching. The control panel 10 can generate corresponding information in response to the operations of the user in the control area 110, so as to control the electrical device 300.

[0087] The portions of the first electrode 3 disposed on the control surface 11 of the panel body 1 and the portions of the second electrode 4 disposed on the control surface 11 of the panel body 1 are both located below the control area 110 in the vertical direction. The control area 110 is the effective area on the control surface 11 that is truly used to interact with the customer. Whether the control area 110 is dew-condensed will directly affect whether the control panel 10 can be used normally. Therefore, detecting the dew-condensation situation of the control area 110 is a key part of the present disclosure.

[0088] In the embodiments of the present disclosure, the circuit elements of the panel body 1 are relatively concentratedly disposed in the control area 110, and there are fewer electrical components below the control area 110, and the temperature is lower. The area closer to the lower part of the control area 110 is more likely to be dew-condensed. By disposing at least a part of the first electrode 3 and the second electrode 4 below the control area 110, in the initial stage of dew-condensation in the control area 110, more dew-condensation can be generated faster below the control area 110, so that a current path can be formed between the first electrode 3 and the second electrode 4 as soon as possible, and it is easier to make the output current of the first electrode 3 smaller, which helps the control unit 2 to detect the dew-condensation situation in the control area 110 earlier.

[0089] Moreover, the water droplets formed by dew-condensation flow from top to bottom. By disposing at least a part of the first electrode 3 and the second electrode 4 below the control area 110, the flowing water droplets formed by dew-condensation in the control area 110 can all pass through the area between the first electrode 3 and the second electrode 4, so that a current path with a smaller resistance is easily formed between the first electrode 3 and the second electrode 4, so that the control unit 2 can detect the dew-condensation situation. This improves the detection result of the control unit 2 for the dew-condensation situation to cover the entire control area 110, and improves the reliability and accuracy of the detection result.

[0090] Combined Figures 2 to 4 As shown, in some embodiments, the control surface 11 of the panel body 1 includes a first plane 111 and a second plane 112. The first plane 111 is parallel to the vertical direction, and the first plane 111 is provided with a control area 110 for interacting with the user. The second plane 112 forms an acute angle with the vertical direction. The second plane 112 is adjacent to the first plane 111 and is located below the first plane 111 in the vertical direction. The second plane 112 gradually deviates towards the inside of the panel body 1 along the vertically downward direction, and both the first electrode 3 and the second electrode 4 are at least partially disposed on the second plane 112.

[0091] The definition of the positional relationship and orientation between the first plane 111 and the second plane 112 in the embodiments of the present disclosure helps the flowing water droplets formed due to condensation on the first plane 111 where the control area 110 is located to flow more smoothly into the second plane 112 where the first electrode 3 and the second electrode 4 are located, so that an electric current path with a smaller resistance is easily formed between the first electrode 3 and the second electrode 4, so that the control unit 2 can detect the condensation situation.

[0092] Combined with Figure 5 As shown, in some embodiments, the control unit 2 includes an analog-to-digital (AD) terminal and a ground (GND) terminal. The first electrode 3 is electrically connected to the analog-to-digital terminal, and the second electrode 4 is electrically connected to the ground terminal.

[0093] Combined with Figure 6 、 Figure 7 and Figure 10 As shown, in the embodiments of the present disclosure, the control panel 10 further includes a communication unit 5. The control unit 2 is communicatively connected to a humidity sensor 20 outside the control panel 10 through the communication unit 5. The communication unit 5 is configured to receive the humidity value sent by the humidity sensor 20, where the humidity sensor 20 and the panel body 1 are located in the same chamber.

[0094] The humidity sensor 20 in the embodiments of the present disclosure is not provided on the control panel 10, but is the original humidity sensor 20 in the chamber. The humidity sensor 20 is configured to detect the humidity value of the air in the chamber. The communication unit 5 can receive the humidity value sent by the humidity sensor 20 and send the humidity value to the control unit 2. The control unit 2 is configured to: obtain the current value of the output current of the first electrode 3, receive the humidity value sent by the humidity sensor 20 outside the control panel 10 through the communication unit 5, and output a condensation alarm signal when it is determined that the current value is less than the current threshold and the humidity value exceeds the humidity threshold.

[0095] It should be noted here that when an electric current path is formed between the first electrode 3 and the second electrode 4, it may not be caused by natural condensation on the control surface 11 of the panel body 1, but may be caused by some unexpected situations. For example, the user may wipe the control surface 11 of the panel body 1 with a wet wipe, resulting in the formation of an electric current path between the first electrode 3 and the second electrode 4. If the current value of the output current of the first electrode 3 is less than the current threshold due to such an unexpected situation, it will cause the control unit 2 to misjudge that the control surface 11 is condensed and output a condensation alarm signal, which will affect the user experience.

[0096] It can be understood that when the air humidity in the compartment where the control panel 10 is located reaches a certain humidity value, the control surface 11 of the panel body 1 will naturally condense. Based on this, an embodiment of the present disclosure sets a humidity threshold, which can be determined according to actual design requirements. Generally speaking, when the humidity value of the air in the compartment where the control panel 10 is located exceeds the humidity threshold, there is a high probability that the control surface 11 of the panel body 1 will condense.

[0097] In an embodiment of the present disclosure, when the control unit 2 determines that the current value of the output current of the first electrode 3 is less than the current threshold, it is also necessary to determine whether the humidity value sent by the humidity sensor 20 in the same compartment as the control panel 10 exceeds the humidity threshold. Only when the control unit 2 determines that the current value of the output current of the first electrode 3 is less than the current threshold and the humidity value exceeds the humidity threshold, will it output a condensation alarm signal. This can, to a certain extent, avoid the control unit 2 misjudging the condensation of the control surface 11 due to accidental situations and outputting a condensation alarm signal, thereby improving the accuracy and reliability of the detection result of the control unit 2 for the condensation situation.

[0098] In some embodiments, the control unit 2 is configured to: obtain the current value of the output current of the first electrode 3, receive the humidity value sent by the humidity sensor 20 outside the control panel 10 through the communication unit 5, and output a condensation alarm signal when it is determined that the current value is less than the current threshold within a preset time period and the humidity value exceeds the humidity threshold. Specifically, the control unit 2 can periodically obtain the current value of the output current of the first electrode 3. Each time a current value of the output current of the first electrode 3 is obtained, the current value of the output current of the first electrode 3 can be compared with the current threshold. When it is determined that the current value is less than the current threshold within a preset time period and the humidity value exceeds the humidity threshold, a condensation alarm signal is output. Here, on the basis of adding the determination of the humidity value sent by the humidity sensor 20 in the same compartment, the control unit 2 further determines that the current value is less than the current threshold within a preset time period before outputting the condensation alarm signal, which can further improve the accuracy and reliability of the detection result of the control unit 2 for the condensation situation.

[0099] Combined with Figures 1 to 5 、 Figure 8 As shown in, an embodiment of the present disclosure provides an electrical appliance 30, which includes an equipment body 301 and the control panel 10 provided in this embodiment of the present disclosure. The control panel 10 is arranged on the equipment body 301.

[0100] Combined with Figures 1 to 7 、 Figure 9As shown, an embodiment of the present disclosure provides an electrical device 30, which includes a device body 301 and a control panel 10 provided by the embodiment of the present disclosure. The control panel 10 is disposed on the device body 301. Among them, the control panel 10 further includes a communication unit 5. In combination with Figure 10 As shown, the control unit 2 is communicatively connected to a humidity sensor 20 outside the control panel 10 through the communication unit 5. The communication unit 5 is configured to receive a humidity value sent by the humidity sensor 20. Among them, the humidity sensor 20 and the panel body 1 are located in the same chamber.

[0101] In combination with Figure 11 As shown, an embodiment of the present disclosure provides a condensation detection method for a control panel. This condensation detection method applies the control unit 2 in the control panel 10 provided by the embodiment of the present disclosure. This condensation detection method includes:

[0102] S1101, the control unit 2 obtains the current value of the output current of the first electrode 3.

[0103] S1102, when the control unit 2 determines that the current value is less than the current threshold, it outputs a condensation alarm signal.

[0104] The control unit 2 can periodically obtain the current value of the output current of the first electrode 3. Each time a current value of the output current of the first electrode 3 is obtained, the current value of the output current of the first electrode 3 can be compared with the current threshold. When it is determined that the current value of the output current of the first electrode 3 is less than the current threshold, a condensation alarm signal is output.

[0105] In some embodiments, the control unit 2 can obtain the current value of the output current of the first electrode 3. When it is determined that the current value is less than the current threshold within a preset time period, a condensation alarm signal is output. Specifically, the control unit 2 can periodically obtain the current value of the output current of the first electrode 3. Each time a current value of the output current of the first electrode 3 is obtained, the current value of the output current of the first electrode 3 can be compared with the current threshold. When it is determined that the current value of the output current of the first electrode 3 is less than the current threshold, a condensation alarm signal is output. Here, when the control unit 2 determines that the current value is less than the current threshold within a preset time period and then outputs a condensation alarm signal, it can ensure the accuracy and reliability of the detection result of the condensation situation by the control unit 2.

[0106] In some embodiments, the control unit 2 obtains the current value of the output current of the first electrode 3, receives the humidity value sent by the humidity sensor 20 outside the control panel 10 through the communication unit 5, and outputs a condensation alarm signal when it is determined that the current value is less than the current threshold and the humidity value exceeds the humidity threshold. Specifically, when the control unit 2 determines that the current value of the output current of the first electrode 3 is less than the current threshold, it also needs to determine whether the humidity value sent by the humidity sensor 20 in the same chamber as the control panel 10 exceeds the humidity threshold. The control unit 2 will only output a condensation alarm signal when it is determined that the current value of the output current of the first electrode 3 is less than the current threshold and the humidity value exceeds the humidity threshold. This can, to a certain extent, prevent the control unit 2 from misjudging condensation on the control surface 11 due to unexpected situations and outputting a condensation alarm signal, thereby improving the accuracy and reliability of the detection result of the control unit 2 for condensation conditions.

[0107] In some embodiments, the control unit 2 obtains the current value of the output current of the first electrode 3, receives the humidity value sent by the humidity sensor 20 outside the control panel 10 through the communication unit 5, and outputs a condensation alarm signal when it is determined that the current value is less than the current threshold within a preset time period and the humidity value exceeds the humidity threshold. Specifically, the control unit 2 can periodically obtain the current value of the output current of the first electrode 3. Each time a current value of the output current of the first electrode 3 is obtained, the current value of the output current of the first electrode 3 can be compared with the current threshold. When it is determined that the current value is less than the current threshold within a preset time period and the humidity value exceeds the humidity threshold, a condensation alarm signal is output. Here, on the basis of adding the determination of the humidity value sent by the humidity sensor 20 in the same chamber, the control unit 2 further determines that the current value is less than the current threshold within a preset time period before outputting a condensation alarm signal, which can further improve the accuracy and reliability of the detection result of the control unit 2 for condensation conditions.
