Description

Technical Field

[0001] This invention belongs to the field of internal display refrigerator control technology, and in particular relates to a control method for preventing accidental touches on the display panel of an internal display refrigerator. Background Technology

[0002] Most refrigerator control panels on the market are located on the outside of the door. A small number of high-end refrigerators use an internal display panel. However, due to the low temperature and high humidity inside the refrigerator, and the frequent presence of water droplets on the food, the display panel may be accidentally touched, causing the mode or temperature to switch, which in turn leads to a difference between the refrigerator's performance and the preset settings.

[0003] In commercially available refrigerators with internal displays, the low internal temperature and high humidity, along with the frequent presence of water droplets on food, can lead to accidental touches on the display panel, causing mode or temperature changes and resulting in discrepancies between the refrigerator's performance and preset settings. For example, the patent with publication number CN210070339U combines the functions of a body fat scale and a refrigerator. Its method to prevent accidental touches primarily uses a pressure sensor to detect data, employing the sensor and at least two contact electrodes to determine if the refrigerator has been accidentally touched. However, this method has significant drawbacks: it adds multiple hardware components, increasing production costs, and if any one of these components fails, the accidental touch prevention function becomes ineffective.

[0004] Therefore, to address the above-mentioned problems, this application solves the issue of accidental touches on the refrigerator by optimizing the control logic of the display panel. Summary of the Invention

[0005] The purpose of this invention is to provide a control method for preventing accidental touches on the display panel of an internal display refrigerator. By optimizing the control logic of the display panel, the problem of accidental touches on existing refrigerator display panels, which can cause the refrigerator's operating mode or temperature to switch, is solved.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a control method for preventing accidental touches on the display panel of an internal display refrigerator, comprising the following steps:

[0008] Step S1: The refrigerator is powered on, the display panel is activated, the button status is checked, and if a button control command is received, then step S2 is executed;

[0009] Step S2: Detect the open / closed status of the refrigerator door;

[0010] If the door is open, the display panel will operate normally.

[0011] If the door is closed, the display panel will automatically lock, and the unlocking time will be extended from 6 seconds to 10 seconds when the door is closed, increasing the difficulty of accidental locking.

[0012] Step S3: With the door closed, all temperature and mode adjustments are invalid.

[0013] Step S4: If the refrigerator detects ≥x erroneous operation controls while the door is closed, the user will be reminded to clean and organize the inside of the refrigerator via APP or / and mini-program or / and voice. By using Wi-Fi instead of voice chip and MCU, the solution achieves the lowest cost while ensuring online upgrade functionality.

[0014] As a preferred technical solution, in step S3, when the refrigerator is in the closed state, the refrigerator cannot adjust the mode and temperature through the display panel; when the refrigerator is in the closed state, the refrigerator can adjust the mode and temperature through an APP or / and a mini program or / and voice recognition.

[0015] As a preferred technical solution, in step S2, a preset signal distance curve is set inside the refrigerator, and at least one signal threshold is preset based on the door distance; the preset signal distance curve is obtained through a learning step; the learning step includes:

[0016] Step S21: The Bluetooth receiver in the refrigerator monitors the Bluetooth transmitter in the refrigerator door, and the Bluetooth receiver analyzes the signal strength of the Bluetooth transmitter.

[0017] Step S22: The measuring device measures the distance from the refrigerator door to the refrigerator, forming a signal distance curve;

[0018] Step S23: Perform the measurement at least three times to obtain at least three signal distance curves. At each distance point, calculate the variance of the signal strength at that distance point on all signal distance curves to finally form the preset signal distance curve.

[0019] Step S24: When a preset door signal is detected, the signal strength is analyzed;

[0020] Step S25: When the signal strength is greater than or equal to the signal threshold, determine that the refrigerator door is in the closed state.

[0021] As a preferred technical solution, the refrigerator stores a preset Bluetooth receiving unit and monitors a preset Bluetooth signal, but the manufacturer of the Bluetooth signal and / or is not recorded in the refrigerator. Any preset distance curve is randomly selected for comparison and monitoring, and the Bluetooth device is sent to the terminal, reminding the terminal to plot the preset signal distance curve.

[0022] As a preferred technical solution, if the preset signal distance curve exceeds the maximum distance of the refrigerator door, then the Bluetooth device is not the refrigerator door and is directly deleted; when the monitored signal threshold is less than the signal threshold and greater than or equal to the signal threshold for the refrigerator door to be fully open, then the refrigerator body is in the open state.

[0023] The present invention has the following beneficial effects:

[0024] This invention optimizes the refrigerator display panel logic. When the refrigerator door is closed, if the refrigerator detects ≥x instances of accidental operation, it will remind the user to clean and tidy the inside of the refrigerator via an app or / and a mini-program or / and voice. This reduces refrigerator production costs and avoids accidental touches.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1

[0031] Please see Figure 1 As shown, the present invention is a control method for preventing accidental touches on the display panel of an internal display refrigerator, comprising the following steps:

[0032] Step S1: The refrigerator is powered on, the display panel is activated, the button status is checked, and if a button control command is received, then step S2 is executed;

[0033] Step S2: Detect the open / closed status of the refrigerator door;

[0034] If the door is open, the display panel will operate normally.

[0035] If the door is closed, the display panel will automatically lock, and the unlocking time will be extended from 6 seconds to 10 seconds when the door is closed, increasing the difficulty of accidental locking.

[0036] Step S3: With the door closed, all temperature and mode adjustments are invalid.

[0037] Step S4: If the refrigerator detects ≥3 misoperation controls while the door is closed, the user will be reminded to clean and organize the inside of the refrigerator via APP or / and mini-program or / and voice. By using Wi-Fi instead of voice chip and MCU, the solution achieves the lowest cost while ensuring online upgrade functionality.

[0038] In step S2, a preset signal distance curve is set inside the refrigerator, and at least one signal threshold is preset based on the door distance; the preset signal distance curve is obtained through a learning step; the learning step includes:

[0039] Step S21: The Bluetooth receiver in the refrigerator monitors the Bluetooth transmitter in the refrigerator door, and the Bluetooth receiver analyzes the signal strength of the Bluetooth transmitter.

[0040] Step S22: The measuring device measures the distance from the refrigerator door to the refrigerator, forming a signal distance curve;

[0041] Step S23: Perform the measurement at least three times to obtain at least three signal distance curves. At each distance point, calculate the variance of the signal strength at that distance point on all signal distance curves to finally form the preset signal distance curve.

[0042] Step S24: When a preset door signal is detected, the signal strength is analyzed;

[0043] Step S25: When the signal strength is greater than or equal to the signal threshold, determine that the refrigerator door is in the closed state.

[0044] The refrigerator stores a preset Bluetooth receiver unit and detects a preset Bluetooth signal, but the manufacturer of the Bluetooth signal and / or is not recorded in the refrigerator. It randomly selects any preset distance curve for comparison and monitoring, and sends the Bluetooth device to the terminal, reminding the terminal to plot the preset signal distance curve.

[0045] If the preset signal distance curve exceeds the maximum distance of the refrigerator door, then the Bluetooth device is not the refrigerator door and is deleted directly; when the monitored signal threshold is less than the signal threshold and greater than or equal to the signal threshold for the refrigerator door to be fully open, then the refrigerator body is in the open state.

[0046] In step S3, when the refrigerator is in the closed state, the refrigerator cannot adjust the mode and temperature through the display panel; when the refrigerator is in the closed state, the refrigerator can adjust the mode and temperature through the APP or / and mini program or / and voice recognition.

[0047] Example 2

[0048] In this embodiment, the following logic processing was performed on the refrigerator based on the internal display panel:

[0049] The door locks when the indicator panel is closed.

[0050] The unlocking operation when the door is closed has been changed from a 6-second long press to a 10-second long press, increasing the difficulty of accidentally locking the door.

[0051] With the door closed, the mode and temperature adjustment are invalid (operations on the display panel are only valid; mini-program / APP / voice recognition can control it normally).

[0052] If the refrigerator detects ≥3 misoperations while the door is closed, it will remind the user to clean and organize the inside of the refrigerator via APP / mini-program / voice. By replacing the voice chip and MCU with Wi-Fi, the solution achieves the lowest cost while ensuring online upgrade functionality.
