DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0019] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

These terms are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second," etc., are used solely for distinction and should not be construed as indicating or implying relative importance.

[0021] It should be noted that, in the absence of conflict, different features in the embodiments of the present invention may be combined with each other.

[0022] The inventors further discovered that in related technologies, defrosting of refrigeration equipment is often performed on a timed basis or automatically triggered based on conditions such as temperature and frost level detected by specific sensors. However, in some special circumstances, users may need to manually initiate the defrost process to quickly resolve frost issues or perform refrigerator maintenance. Existing manual defrosting operations are either complex and require specialized personnel, or lack a clear, convenient, and safe user interface, failing to meet the needs of ordinary users for flexible defrost control during daily use.

[0023] In order to solve the technical problems mentioned in the aforementioned background technology and the technical problems mentioned above, the inventors innovatively designed the following technical solutions, and the specific implementation solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] See Figure 1 , Figure 1 A schematic flow chart of a defrost control method according to an embodiment of the present invention is provided. Figure 4The refrigeration device 10 shown is a control module used in refrigeration equipment. The refrigeration equipment also includes a door switch detection module, a lighting control module and an evaporator. The door switch detection module is arranged inside the refrigeration equipment to detect the switch action of the door body of the refrigeration equipment. The lighting control module is arranged inside the refrigeration equipment. The lighting control module is electrically connected to the indicator light inside the refrigeration equipment to control the operation of the indicator light. The control module is electrically connected to the door switch detection module, the lighting control module and the evaporator. The evaporator is arranged inside the refrigeration equipment to absorb heat from the evaporation of the liquid refrigerant to achieve refrigeration of the refrigeration equipment. It can be understood that the refrigeration equipment can be a refrigerator, a freezer, or other equipment used for refrigeration. The following will focus on Figure 1 The defrost control method may include the following steps: Step S110: Acquire the first switch action of the door body detected by the door switch detection module.

[0025] The door body's switching action includes an opening action and a closing action. It is understandable that the door body is also connected to a door switch. When the door body's switching action is an opening action, the door switch is in a pop-up state. When the door body's switching action is a closing action, the door switch is in a pressed state.

[0026] Specifically, the door switch detection module may detect the switching action of the door body by directly detecting the switching action of the door body, or may detect the state of the door switch to determine the switching action of the door body, which is not limited in this embodiment.

[0027] Step S120: If the first switch action is the first preset switch action, a first lighting control instruction is sent to the lighting control module to control the working state of the indicator light through the first lighting control instruction.

[0028] The first preset switch action can be an opening action, a closing action, or an opening action first and then a closing action. The first preset switch action can be set according to actual needs. For example, the first preset switch action can be an opening action 3 times and a closing action 3 times.

[0029] Furthermore, the operating state of the indicator light can be a lit state, an off state, a flashing state, or a dimming state. The first lighting control instruction can control the indicator light to change from an off state to a lit state, or to keep the indicator light flashing, or to change from an off state to a dimming state. The first lighting control instruction can be determined based on actual needs.

[0030] Step S130: Acquire a first duration of operation of the indicator light under the first lighting control instruction detected by the lighting control module.

[0031] The first duration may be a duration of a change in state based on the first lighting control instruction, or a duration of a maintenance state based on the first lighting control instruction.

[0032] Exemplarily, the first duration may be the duration of a change from an off state to a lit state, or the first duration may be the duration of a flashing state of the indicator light.

[0033] Step S140: When the first duration is less than or equal to the first preset duration, obtaining a second switch action of the door body detected by the door switch detection module.

[0034] In the embodiment of the present application, the second switching action may be the same as or different from the first switching action. Preferably, the second switching action is different from the first switching action.

[0035] For example, if the first switching action is an on action, the second switching action may be a off action; if the first switching action is an on action three times and a off action four times, the second switching action may be a keep-on action.

[0036] Step S150: If the second switch action is the second preset switch action, a second lighting control instruction is sent to the lighting control module, so that the working state of the indicator light is controlled by the second lighting control instruction.

[0037] The second preset switch action may be the same as or different from the first preset switch action. Similarly, the second lighting control instruction may be the same as or different from the first lighting control instruction.

[0038] Step S160: obtaining a second duration of the indicator light working under the second lighting control instruction detected by the lighting control module, and obtaining a third switch action of the door body detected by the door switch detection module.

[0039] In this embodiment, the third switching action may be the same as the second switching action and / or the first switching action, or may be different from the second switching action and / or the first switching action, which is not limited in this embodiment.

[0040] Step S170: If the second duration is greater than or equal to the second preset duration, and the third switching action is the third preset switching action, defrosting the evaporator.

[0041] The defrost process may involve the control module sending a heating instruction to a heating module for heating the evaporator, thereby controlling the heating module to perform heating through the heating instruction, thereby performing defrost processing on the evaporator. The defrost process may also involve the control module sending a high-temperature, high-pressure gas introduction instruction to the compressor, thereby performing defrost processing on the evaporator through the high-temperature, high-pressure gas introduced by the compressor. The defrost process may also involve the control module sending a defrost instruction to a defrost processing module with a defrost function, thereby causing the defrost control module to control the refrigeration equipment to perform defrost processing. Furthermore, the defrost control module may include a defrost circuit. This embodiment does not limit the defrost process.

[0042] The solution provided by the present invention clarifies the user's defrosting needs by detecting the opening and closing actions of the user's refrigeration equipment door, and then realizes the defrosting operation based on the user's needs, simplifies the user's manual defrosting operation, facilitates the user's maintenance of the refrigeration equipment, ensures that the refrigeration equipment can be forced to defrost in a timely and effective manner, and improves the performance of the refrigeration equipment and user experience.

[0043] See Figure 2 , Figure 2 A schematic flow chart of the steps of a defrost control method provided in another embodiment of the present invention will be described below. Figure 2 The defrost control method may include the following steps: Step S210: obtaining a door switching frequency detected by the door switch detection module within a first preset time period as a first switching frequency.

[0044] Here, frequency refers to the ratio of number of times to time. It is understood that the first switching frequency refers to the ratio between the number of times the door is opened and closed and the first preset duration. Since the door opening and closing involve two states, open and closed, the first switching frequency can be the frequency of the door opening within the first preset duration, the frequency of the door closing within the first preset duration, or the frequency of both the door opening and closing within the first preset duration, and this embodiment does not limit this. For example, if the door is opened once within 10 seconds, the first switching frequency is 1 time / 10 seconds.

[0045] Step S220: If the first switching frequency represents that the opening frequency and closing frequency of the door body within the first preset time period reach the first preset frequency, the first switching action is determined to be the first switch preset action, and a first lighting control instruction is sent to the lighting control module.

[0046] In this embodiment, since the door opening and closing are related, that is, when the door is in the open state and it is necessary to record the door opening again, the door needs to be operated to close. When the frequency of opening and closing the door reaches a first preset frequency, it indicates that the user has opened and closed the door multiple times within a first preset time period, thereby avoiding the problem of false triggering caused by a single state triggering the first lighting control instruction.

[0047] Step S230: Acquire a first duration of operation of the indicator light under the first lighting control instruction detected by the lighting control module.

[0048] Step S240: When the first duration is less than or equal to the first preset duration, obtaining a second switch action of the door body detected by the door switch detection module.

[0049] The detailed description of steps S230 to S240 can refer to the detailed description of steps S130 to S140 in the aforementioned embodiment, which will not be repeated here.

[0050] Step S250: If the door body is in a closed state and maintains the third preset time, and after the door body maintains the closed state for the third preset time, it maintains the open state for the fourth preset time, then the door body is determined to be the second preset switch action, and a second lighting control instruction is sent to the lighting control module.

[0051] Step S260: obtaining a second duration of the indicator light detected by the lighting control module to be started and stopped based on the second lighting control instruction, and obtaining a third switch action of the door body detected by the door switch detection module.

[0052] The detailed description of step S260 can refer to the detailed description of step S160 in the above embodiment, which will not be repeated here.

[0053] Step S270: If the second duration is greater than or equal to the second preset duration, and the door remains open for the fifth preset duration, the third switch action of the door is determined to be the third preset switch action, and the evaporator is defrosted.

[0054] Step S280: Acquire the internal temperature of the refrigeration equipment detected by the defrost sensor module.

[0055] The refrigeration device further includes a defrost sensor module, which is arranged inside the refrigeration device and used to detect the temperature inside the refrigeration device. The defrost sensor module is electrically connected to the control module.

[0056] Step S290: If the internal temperature is greater than or equal to the preset temperature, the refrigeration equipment is controlled to stop the defrosting process.

[0057] The preset temperature may be determined based on the temperatures at which defrosting is completed for multiple times, or may be the temperature at which defrosting is completed determined based on actual conditions.

[0058] In this embodiment, when the internal temperature of the refrigeration device is greater than or equal to the preset temperature, it is determined that the frost layer condensed on the evaporator has evaporated. Even if some frost remains, it will be evaporated by the residual heat during the cooling process of the evaporator. At this time, the refrigeration device can be controlled to stop the defrosting process.

[0059] In an optional embodiment, the continuous defrost time corresponding to the defrost process is obtained; if at least one of the internal temperature or the continuous defrost time satisfies the corresponding preset condition, the refrigeration equipment is controlled to stop the defrost process.

[0060] In this embodiment, when the defrost duration meets a preset condition, it indicates that the defrost process on the evaporator has continued for a period of time. The frost layer condensed on the evaporator will evaporate due to the defrost process. The longer the defrost process lasts, the more complete the frost layer will evaporate. Controlling the refrigeration equipment's defrost termination based on the defrost duration and internal temperature can avoid the adverse effects of a defrost sensor module detection failure and improve the control accuracy of the defrost process.

[0061] In the specific implementation process, taking the refrigeration equipment as a refrigerator as an example, an evaporator, a door switch, a door switch detection module for detecting the door switch action, an LED indicator light, a lighting control module for controlling the operation of the LED indicator light, a control module, and a defrost control module for controlling the refrigeration equipment to perform defrost processing are installed inside the refrigerator, and the various components are correctly connected and can work normally.

[0062] When the user decides to defrost the refrigerator and opens the door, the door switch detection module detects the door switch movement, signals that the door has been opened, and transmits this signal to the control module. The control module then activates a timer function, monitoring the door switch movement over the next 15 seconds. For example, the user rapidly closes and opens the refrigerator door multiple times, causing the door switch to complete 10 "open-close" cycles within 15 seconds. Each time the door switch moves, the door switch detection module sends a corresponding electrical signal to the control module, which counts these signals using its internal counting module. When the control module detects 10 door switch movements within 15 seconds, it immediately sends a control signal to the lighting control module, causing the LED indicator to flash rapidly at a frequency of 2 Hz. This flashing can be achieved by varying the LED's drive current or pulse signal. For example, the current can be turned on every 0.25 seconds, causing the LED indicator to turn on for 0.25 seconds and off for 0.25 seconds, creating a 2 Hz flashing effect. This flashing state persists for 20 seconds, reminding the user that the defrost preparation phase has successfully begun. To remind users more clearly, when the LED indicator light enters the flashing state, a prompt sound will be given to the user.

[0063] Within 20 seconds of the LED indicator rapidly flashing, the user closes the refrigerator door and holds it closed for 4 seconds. At this point, the door switch is in the "pressed" state, and the door switch detection module continuously sends a door-closed signal to the control module. The control module detects the duration of the door switch signal to determine whether the 4-second continuous pressed condition is met. Four seconds later, the user opens the refrigerator door and holds it open for 4 seconds. At this point, the door switch is in the "pop-up" state, and the door switch detection module sends a door-open signal to the control module. The control module similarly detects the duration of the door switch signal to determine whether the 4-second continuous pop-up condition is met. If the control module detects the door switch being "pressed" for 4 seconds, followed by another 4-second continuous pop-up state, it controls the lighting control module to send a control signal to the LED indicator, causing it to stop rapidly flashing and turn off. This state remains off for at least 2 seconds, confirming that the LED indicator is permanently off. After the LED indicator turns permanently off, the refrigerator door remains in the "pop-up" state that triggered the LED indicator to turn permanently off for 10 seconds. The control module uses a timing function to monitor this 10-second period. During this period, the door open detection module continuously sends door open signals to the control module. When the 10-second period expires, the control module confirms that all forced defrost triggering conditions have been met and sends a start signal to the refrigerator's defrost control module, triggering defrost. Simultaneously, the control module resumes normal control logic for the LED indicator, which illuminates or extinguishes according to the actual door open / close status.

[0064] After the refrigerator enters the defrost cycle, the defrost sensor module begins monitoring the evaporator surface temperature in real time. The defrost sensor module typically uses a temperature-sensitive element, such as a thermistor, whose resistance changes with temperature. By measuring the defrost sensor's resistance, the control module calculates the evaporator surface temperature. The control module pre-stores a preset defrost exit temperature. When the temperature detected by the defrost sensor module reaches or exceeds this preset value, perhaps 8°C, the defrost sensor module transmits a corresponding temperature signal to the control module. Upon receiving this signal, the control module determines that the defrost exit conditions have been met and sends a stop signal to the refrigerator's defrost control module, causing the refrigerator to exit the defrost function and return to normal refrigeration operation. The control module also includes a maximum defrost time counter, which begins counting when the refrigerator enters the defrost cycle. If during the defrost process, the defrost sensor module has not detected a signal that meets the exit temperature conditions, but the defrost time has reached the preset maximum defrost time (for example, 60 minutes), the control module will also send a stop signal to the defrost control module, and the refrigerator will exit the defrost process to prevent unnecessary damage to the refrigerator or energy waste due to a long defrost process.

[0065] The solution provided by the present invention determines the user's defrosting needs by detecting the opening and closing actions of the user's refrigeration equipment door, and then realizes the defrosting operation based on the user's needs, simplifies the user's manual defrosting operation, facilitates the user to maintain the refrigeration equipment, and ensures that the refrigeration equipment can be forced to defrost in a timely and effective manner. Moreover, after the defrosting process is performed, the exit of the defrosting process will be automatically controlled according to the internal temperature of the refrigeration equipment, which can not only improve the performance of the refrigeration equipment, but also further enhance the user experience.

[0066] Based on the same inventive concept, see Figure 3 , Figure 3 The present embodiment provides a schematic diagram of the functional modules of a defrost control device 100. The present embodiment can divide the functional modules of the defrost control device 100 according to the above method embodiment.

There may be other division methods for actual implementation.
