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 need to be further defined or explained in subsequent drawings.

[0020] In the description of the present invention, it should be noted that the terms "upper" and "lower," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is typically placed when in use. 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, taking refrigerators as an example of refrigeration equipment, most refrigerators only rely on the compressor in the refrigerator for direct cooling, and lack an active circulation mechanism for low-temperature environments. This leads to insufficient air circulation in the refrigerator compartment, and the condensed water cannot be effectively evaporated, causing the humidity in the refrigerator compartment to be continuously too high. In addition, the natural heat dissipation efficiency is low in low-temperature environments, and localized freezing is prone to occur in the refrigerator compartment.

[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 method for controlling a refrigeration device according to an embodiment of the present invention is provided. Figure 4The refrigeration device 10 shown is a control module used in a refrigeration device. The control module can be a central control module in the refrigeration device, or it can be a module that is only used to execute the control method in this embodiment. The refrigeration device also includes an ambient temperature detection module, an internal temperature detection module, a timing module, and a refrigeration fan. The ambient temperature detection module is arranged outside the refrigeration device. The ambient temperature detection module can be arranged in a hinged cover outside the refrigeration device, or it can be arranged on the side wall of the refrigeration device. The ambient temperature detection module is used to detect the ambient temperature of the refrigeration device. The internal temperature detection module is arranged inside the refrigeration device. The internal temperature detection module is used to detect the internal temperature of the refrigeration device. The timing module is arranged inside the refrigeration device. The timing module is used to time the duration of the opening and closing state of the damper in the refrigeration device and the duration of the working state of the compressor in the refrigeration device. The refrigeration fan is arranged inside the refrigeration device. The refrigeration fan is used to promote the circulation of cold air in the refrigeration device. The control module is electrically connected to the ambient temperature detection module, the internal temperature detection module, the timing module, and the refrigeration fan. It can be understood that the refrigeration device can be a refrigerator, a freezer, or other equipment used for refrigeration. The following will focus on Figure 1 The control method of the refrigeration equipment may specifically include the following steps: Step S110: obtaining a first ambient temperature of the environment where the refrigeration device is located, which is detected by the ambient temperature detection module at the time of data collection.

[0025] The data collection time may be the current time or the collection time after a preset time interval, which is not limited here.

[0026] Step S120: Acquire a first internal temperature inside the refrigeration device detected by the internal temperature detection module at the data collection time.

[0027] The first internal temperature may be the temperature of the geometric center of the refrigeration device, or the temperature of the location where the internal temperature detection module is located in the refrigeration device.

[0028] Step S130: Acquire a first duration of time during which the damper is in the open state and a second duration of time during which the compressor is in the shutdown state, detected by the timing module at the time of data collection.

[0029] The first duration refers to the duration between the time the damper was in the open state and the time the data was collected. The second duration refers to the duration between the time the compressor was in the shut-down state and the time the data was collected. It should be noted that the operating status of the compressor and the open / closed status of the damper can be detected by a status detection module within the refrigeration equipment.

[0030] Step S140: Determine a first control instruction according to the first ambient temperature, the first internal temperature, the first duration, and the second duration, and control the refrigeration fan to operate and the damper to be in an open state through the first control instruction.

[0031] In an embodiment of the present application, the first ambient temperature, the first internal temperature, the first duration, and the second duration can be compared with corresponding thresholds, and the first control instruction can be determined if all or part of the data meets the corresponding thresholds. The first control instruction can also be determined by comparing the first ambient temperature with the first internal temperature and the first duration with the second duration, which is not limited in this embodiment.

[0032] The solution provided by the present invention comprehensively considers the ambient temperature, internal temperature, interval length of the damper opening and interval length of the compressor of the refrigeration equipment to determine whether to turn on the refrigeration fan and the damper, and then determines whether to actively circulate air inside the refrigeration equipment, thereby ensuring the effective evaporation of condensed water inside the refrigeration equipment, avoiding local freezing in the refrigeration equipment, and also avoiding the problem of high energy consumption of the refrigeration equipment, thereby improving the user experience.

[0033] In some embodiments, the refrigeration equipment includes a cold storage room. Figure 2 , Figure 2 A schematic flow chart of a control method for a refrigeration device according to another embodiment of the present invention is provided below. Figure 2 The control method of the refrigeration equipment may specifically include the following steps: Step S210: obtaining a first ambient temperature of the environment where the refrigeration device is located, which is detected by the ambient temperature detection module at the time of data collection.

[0034] Step S220: Acquire a first internal temperature inside the refrigeration device detected by the internal temperature detection module at the data collection moment.

[0035] Step S230: Acquire a first duration of time during which the damper is in the open state and a second duration of time during which the compressor is in the shutdown state, detected by the timing module at the data collection moment.

[0036] The detailed description of steps S210 to S230 can refer to the detailed description of steps S110 to S130 in the aforementioned embodiment, which will not be repeated here.

[0037] Step S240: Acquire the target bottom temperature of the bottom of the refrigerating chamber at the time of data collection.

[0038] Since condensed water droplets easily accumulate at the bottom of the refrigerator compartment, it can easily lead to excessive humidity inside the refrigerator compartment, which in turn causes ice to form at the bottom of the refrigerator compartment, thereby increasing the energy consumption of the refrigeration equipment. Therefore, to avoid ice forming at the bottom of the refrigerator compartment, a target bottom temperature of the refrigerator compartment bottom can be set at the time of data collection. The target bottom temperature can be obtained by a temperature detection module installed at the bottom of the refrigerator compartment, or by analyzing the collected internal temperature of the refrigerator compartment through an internal temperature detection module to obtain the target bottom temperature of the refrigerator compartment bottom, which is not limited here.

[0039] Step S250: Determine a second control instruction based on the target bottom temperature, the first ambient temperature, the first internal temperature, the first duration, and the second duration, and control the refrigeration fan to operate and the damper to be in an open state through the second control instruction.

[0040] The second control instruction and the first control instruction are different control instructions.

[0041] In this embodiment, the target bottom temperature, the first ambient temperature, the first internal temperature, the first duration, and the second duration can be compared with corresponding thresholds, and the second control instruction is determined if all or part of the data meets the corresponding thresholds. The second control instruction can also be determined by comparing the first ambient temperature, the first internal temperature, and the target bottom temperature, and comparing the first duration and the second duration, which is not limited in this embodiment.

[0042] In some embodiments, a second control instruction is determined based on a target bottom temperature, a first ambient temperature, a first internal temperature, a first duration, and a second duration, and the step of controlling the refrigeration fan to operate and the damper to be in an open state by the second control instruction includes: obtaining a temperature difference between the target bottom temperature and the first internal temperature. Comparing the relationship between the temperature difference and a temperature difference threshold corresponding to the temperature difference, the first ambient temperature and the ambient temperature threshold corresponding to the first ambient temperature, the first internal temperature and the internal temperature threshold corresponding to the first internal temperature, the first duration and the first duration threshold corresponding to the first duration, and the second duration and the second duration threshold corresponding to the second duration. If the temperature difference is greater than or equal to the temperature difference threshold, the first ambient temperature is less than or equal to the ambient temperature threshold, the first internal temperature is greater than or equal to the internal temperature threshold, the first duration is less than the first duration threshold, and the second duration is greater than or equal to the second duration threshold, then determining the second control instruction and controlling the refrigeration fan to operate and the damper to be in an open state by the second control instruction.

[0043] In this embodiment, when the temperature difference between the target bottom temperature and the first internal temperature is too large and the first duration is less than the first duration threshold, it indicates that when the damper interval does not reach the preset duration, cold air is deposited inside the refrigeration equipment and the internal cold air circulation is insufficient. In order to avoid the internal cold air deposition from bringing greater impact on the refrigeration equipment, when the temperature difference is greater than or equal to the temperature difference threshold, the first ambient temperature is less than or equal to the ambient temperature threshold, the first internal temperature is greater than or equal to the internal temperature threshold, the first duration is less than the first duration threshold, and the second duration is greater than or equal to the second duration threshold, the refrigeration fan is controlled by the second control instruction to work, and the damper is controlled to be in the open state to promote air circulation inside the refrigeration equipment.

[0044] For example, taking the temperature difference threshold of 1.5°C, the ambient temperature threshold of 10°C, the internal temperature threshold of 0°C, the first duration threshold of 90 minutes, and the second duration threshold of 10 minutes as an example, when the temperature difference is greater than or equal to 1.5°C, the first ambient temperature is 15°C, the first internal temperature is 5°C, the first duration is 70 minutes, and the second duration is 15 minutes, a second control instruction is determined, and the refrigeration fan is controlled to operate in advance and the damper is controlled to be in the open state through the second control instruction.

[0045] The solution provided by the present invention comprehensively considers the ambient temperature, internal temperature, bottom temperature of the refrigeration equipment, the interval length of the damper opening, and the interval length of the compressor shutdown to determine whether to turn on the refrigeration fan and the damper, and then determines whether to actively circulate air inside the refrigeration equipment in advance, thereby ensuring the effective evaporation of condensed water inside the refrigeration equipment, avoiding local freezing in the refrigeration equipment, and also avoiding the problem of high energy consumption of the refrigeration equipment, thereby improving the user experience.

[0046] See Figure 3 , Figure 3 A flowchart of a control method for a refrigeration device according to another embodiment of the present invention is provided below. Figure 3 The control method of the refrigeration equipment may specifically include the following steps: Step S310: obtaining a first ambient temperature of the environment where the refrigeration device is located, which is detected by the ambient temperature detection module at the time of data collection.

[0047] Step S320: Acquire a first internal temperature inside the refrigeration device detected by the internal temperature detection module at the data collection moment.

[0048] Step S330: Acquire a first duration of time during which the damper is in the open state and a second duration of time during which the compressor is in the shutdown state, detected by the timing module at the data collection moment.

[0049] The detailed description of steps S310 to S330 can refer to the detailed description of steps S110 to S130 in the above embodiment, which will not be repeated here.

[0050] Step S340: Compare the relationship between the first ambient temperature and the ambient temperature threshold corresponding to the first ambient temperature, the first internal temperature and the internal temperature threshold corresponding to the first internal temperature, the first duration and the first duration threshold corresponding to the first duration, and the second duration and the second duration threshold corresponding to the second duration.

[0051] Step S350: If the first ambient temperature is less than or equal to the ambient temperature threshold, the first internal temperature is greater than or equal to the internal temperature threshold, the first duration is greater than or equal to the first duration threshold, and the second duration is greater than or equal to the second duration threshold, determine the first control instruction, and control the refrigeration fan to operate and control the damper to be in the open state through the first control instruction.

[0052] Among them, the ambient temperature threshold, the internal temperature threshold, the first duration threshold, and the second duration threshold can be determined according to actual needs or based on empirical values, and are not limited here.

[0053] In this embodiment, when the first ambient temperature, the first internal temperature, the first duration and the second duration all meet the corresponding conditions, the first control instruction is determined, and the refrigeration fan is controlled to operate and the damper is controlled to be in an open state through the first control instruction.

[0054] For example, taking the ambient temperature threshold of 10°C, the internal temperature threshold of 5°C, the first duration threshold of 90 minutes, and the second duration threshold of 10 minutes as an example, when the first ambient temperature is 15°C, the first internal temperature is 15°C, the first duration is 100 minutes, and the second duration is 20 minutes, a first control instruction is determined, and the refrigeration fan is controlled to operate and the damper is controlled to be in an open state through the first control instruction, thereby circulating air inside the refrigeration equipment, thereby effectively cooling and regulating the humidity inside the refrigeration equipment, and improving the operating efficiency and service life of the refrigeration equipment.

[0055] In some embodiments, the internal ambient temperature threshold includes the shutdown point temperature inside the refrigeration equipment. If the first ambient temperature is less than or equal to the ambient temperature threshold, the first internal temperature is greater than or equal to the internal temperature threshold, the first duration is greater than or equal to the first duration threshold, and the second duration is greater than or equal to the second duration threshold, the first control instruction is determined, and the refrigeration fan is controlled to operate and the damper is controlled to be in an open state through the first control instruction. The steps include: if the first ambient temperature is less than or equal to the ambient temperature threshold, the first internal temperature is greater than or equal to the shutdown point temperature, the first duration is greater than or equal to the first duration threshold, and the second duration is greater than or equal to the second duration threshold, the first control instruction is determined, and the refrigeration fan is controlled to operate and the damper is controlled to be in an open state through the first control instruction.

[0056] The shutdown point temperature refers to the temperature at which the refrigeration device stops working. For example, if the refrigeration device is a refrigerator, the shutdown point temperature is the refrigeration shutdown point temperature, which is 0°C.

[0057] Step S360: After the refrigeration fan and the damper operate according to the first control instruction, a second internal temperature inside the refrigeration device is obtained.

[0058] Step S370: Compare the second internal temperature with the internal temperature threshold.

[0059] Step S380: If the second internal temperature is lower than the internal temperature threshold, a third control instruction is determined, and the refrigeration fan is controlled to be turned off and the damper is controlled to be in a closed state through the third control instruction.

[0060] The third control instruction is different from the first control instruction and the second control instruction.

[0061] In this embodiment, when the refrigeration fan is turned on and the damper is in the open state, cooling and air circulation within the refrigeration device are accelerated, thereby reducing the internal temperature of the refrigeration device. After the refrigeration fan and the damper operate according to the first control instruction, a second internal temperature within the refrigeration device is obtained and compared with an internal temperature threshold. If the second internal temperature is less than the internal temperature threshold, a third control instruction is determined, and the refrigeration fan is controlled to be turned off and the damper is controlled to be in the closed state through the third control instruction, thereby avoiding adverse effects caused by excessively low internal temperature of the refrigeration device.

[0062] In some embodiments, after the refrigeration fan and damper are operating according to the first control instruction and obtaining the second internal temperature inside the refrigeration device, the method further includes obtaining the operating status of the compressor. If either the operating status of the compressor or the second internal temperature satisfies a corresponding condition, a third control instruction is determined, and the refrigeration fan is controlled to be turned off and the damper is controlled to be in a closed state according to the third control instruction.

[0063] In a refrigeration device, a compressor is used to compress refrigerant gas, thereby driving the refrigerant gas to circulate within the refrigeration device, thereby causing air to circulate within the refrigeration device. In this embodiment, when the compressor is in an operating state for a period of time, the internal temperature of the refrigeration device can be reduced and the air inside the refrigeration device can be circulated. Therefore, when the operating state of the compressor meets the corresponding conditions and / or the second internal temperature meets the corresponding conditions, a third control instruction is determined, and the third control instruction is used to control the refrigeration fan to be turned off and the damper to be in a closed state, thereby avoiding the adverse effects caused by the excessively low internal temperature of the refrigeration device.

[0064] For example, the condition corresponding to the working state of the compressor is that the working state of the compressor is in the on state, and the condition corresponding to the second internal temperature is that the second internal temperature is less than 0°C. When the working state of the compressor is in the on state and the second internal temperature is 0°C, at this time, the third control instruction is determined to control the refrigeration fan to be turned off and the damper to be in the closed state through the third control instruction. When the working state of the compressor is in the on state and the second internal temperature is -1°C, at this time, the third control instruction is determined to control the refrigeration fan to be turned off and the damper to be in the closed state through the third control instruction. When the working state of the compressor is in the off state and the second internal temperature is 2°C, the refrigeration fan is kept on and the damper is controlled to be in the open state.

[0065] In other embodiments, after the refrigeration fan and the damper are operated according to the first control instruction and the second internal temperature of the refrigeration device is obtained, the method further includes obtaining a second ambient temperature of the refrigeration device. If any one of the second ambient temperature, the operating state of the compressor, and the second internal temperature satisfies a corresponding condition, a third control instruction is determined to control the refrigeration fan to be turned off and the damper to be in a closed state through the third control instruction.

[0066] When the ambient temperature of the refrigeration device is too low, it will cause difficulty in starting the compressor inside the refrigeration device. In this embodiment, when the ambient temperature of the refrigeration device meets the corresponding conditions, the compressor inside the refrigeration device can start normally and air circulation inside the refrigeration device can be achieved through the compressor.

[0067] For example, the condition corresponding to the second ambient temperature is that the second ambient temperature is greater than 10°C, the condition corresponding to the working state of the compressor is that the working state of the compressor is in the on state, and the condition corresponding to the second internal temperature is that the second internal temperature is less than 0°C. When the second ambient temperature is 12°C, the working state of the compressor is in the off state, and the second internal temperature is 0°C, at this time, the third control instruction is determined to control the refrigeration fan to be turned off through the third control instruction, and to control the damper to be in the closed state. When the second ambient temperature is 8°C, the working state of the compressor is in the on state, and the second internal temperature is -1°C, at this time, the third control instruction is determined to control the refrigeration fan to be turned off through the third control instruction, and to control the damper to be in the closed state. When the second ambient temperature is 12°C, the working state of the compressor is in the off state, and the second internal temperature is 2°C, at this time, the refrigeration fan is kept on, and the damper is controlled to be in the open state.

[0068] The solution provided by the present invention comprehensively considers the ambient temperature, internal temperature, interval length of the damper opening and interval length of the compressor of the refrigeration equipment to determine whether to turn on the refrigeration fan and the damper, and then determines whether to actively circulate air inside the refrigeration equipment, thereby ensuring the effective evaporation of condensed water inside the refrigeration equipment and avoiding local freezing in the refrigeration equipment. When the preset air circulation exit conditions are reached, the air circulation is exited in time, reducing the number of times the compressor in the refrigeration equipment is started. At the same time, it also avoids the problem of high energy consumption of the refrigeration equipment and improves the user experience.
