The refrigeration device comprises a fan, a detection device capable of obtaining the deformation degree of the fan and capable of adjusting the refrigeration efficiency of the refrigeration device. The refrigeration device and the control method thereof provided by the application detect the deformation of the fan by the detection device. When the detection device detects the deformation of the fan, it indicates that the temperature of the environment where the fan is located is too high, and the fan has been deformed due to the influence of the temperature.

Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a refrigeration device and its control method. Background Technology

[0002] With the improvement of people's living standards and the changes brought about by global warming in recent years, ambient temperatures are rising, and refrigerators have long been an essential choice for household appliances. Consequently, consumers have increasingly higher demands for refrigerators, seeking a perfect integration between the refrigerator and home décor. Therefore, built-in or flush-mounted refrigerators have become popular and represent a future trend. Both built-in and flush-mounted refrigerators utilize bottom cooling, which places the condenser inside the compressor compartment. Heat is then dissipated through air convection generated by the condenser fan, making the condenser fan a crucial element in heat dissipation.

[0003] Since built-in or flush-mounted refrigerators are mostly installed inside cabinets, and the back and sides of the refrigerator are in close contact with the surrounding cabinets, their heat dissipation method is different from that of traditional refrigerators. An external condenser needs to be installed in the compressor compartment, and a condenser fan needs to be installed next to the condenser. The air convection generated by the fan's rotation will remove the heat generated by the condenser. Because the heat is large and the temperature is high, when the heat cannot be dissipated in time and the temperature of the compressor compartment rises, the condenser fan will deform due to the increased temperature. It may also cause deformation at the installation location of the condenser fan, eventually leading to problems such as fan misalignment or falling off, which seriously affects the reliability of the refrigeration equipment. Summary of the Invention

[0014] The refrigeration equipment includes a refrigerator.

[0015] A control method for the above-mentioned refrigeration equipment includes: Obtain the degree of fan deformation and compare it with a preset degree; If the deformation of the fan is greater than or equal to a preset level, the cooling efficiency of the refrigeration equipment will be reduced.

To avoid problems such as fan displacement and interference with other structures, unreliable operation, or even falling off when the fan or refrigeration equipment continues to work, the detection device can reduce the ambient temperature of the fan and the fan speed by reducing the refrigeration efficiency of the refrigeration equipment, thereby preventing further deformation of the fan and ensuring the reliability of the fan and refrigeration equipment.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] With the improvement of people's living standards and the changes in global warming in recent years, ambient temperatures are getting higher and higher, and refrigerators have long been an essential choice for household appliances. Consequently, consumers' requirements for refrigerators are also increasing, with users seeking a perfect integration between the refrigerator and home décor. Therefore, built-in or flush-mounted refrigerators have become popular and represent a future trend. Both built-in and flush-mounted refrigerators use bottom cooling, which involves placing the condenser inside the compressor compartment and using air convection generated by a condenser fan to remove heat. Therefore, the condenser fan plays a crucial role in heat dissipation. Since built-in or flush-mounted refrigerators are mostly installed within cabinets, and the back and sides of the refrigerator are in close contact with the surrounding cabinets, the heat dissipation method differs from traditional refrigerators. An external condenser needs to be installed in the compressor compartment, and a condenser fan needs to be installed next to the condenser. The air convection generated by the fan's rotation removes the heat generated by the condenser. Because the heat is relatively large and the temperature is high, if the heat cannot be dissipated in time, causing the temperature in the compressor compartment to rise, the condenser fan may deform due to the increased temperature. This could also cause deformation at the condenser fan mounting point, ultimately leading to problems such as fan misalignment or falling off, seriously affecting the reliability of the refrigeration equipment. This application provides a method... Figures 1 to 3 The refrigeration equipment shown includes: a fan 1; and a detection device capable of acquiring the degree of deformation of the fan 1 and adjusting the refrigeration efficiency of the refrigeration equipment. The detection device detects the deformation of the fan 1. When the detection device detects deformation of the fan 1, it indicates that the ambient temperature of the fan 1 is too high, and the fan 1 has deformed due to the temperature (e.g., the shape of the fan blades changes or the support of the fan 1 deforms, causing a change in the rotation area of ​​the fan blades). To avoid problems such as fan 1 displacement leading to interference with other structures, unreliable operation, or even falling during continued operation of the fan 1 or the refrigeration equipment, the detection device can reduce the ambient temperature of the fan 1 and the fan speed by reducing the refrigeration efficiency of the refrigeration equipment, thereby preventing further deformation of the fan 1 and ensuring the reliability of the fan 1 and the refrigeration equipment.

[0029] In one embodiment, the detection device includes a light emitting structure 2 and a light receiving structure 3. The light receiving structure 3 can receive the light emitted by the light emitting structure 2. A fan 1 is disposed between the light emitting structure 2 and the light receiving structure 3, and when the fan 1 is in operation, the fan 1 can block the light emitted by the light emitting structure 2. The light emitting structure 2 can emit light, and the light can illuminate the light receiving structure 3, causing the working state of the light receiving structure 3 to change. When the fan 1 rotates, the fan 1 passes between the light emitting structure 2 and the light receiving structure 3, blocking the light emitted by the light emitting structure 2, thereby changing the working state of the light receiving structure 3. When the fan 1 is not deformed, the duration of light blocking by the fan 1 is fixed when the fan 1 rotates at a set speed. However, when the fan 1 is deformed, the duration of light blocking by the fan 1 changes when the fan 1 rotates at the same speed again, thus determining that the fan 1 has deformed. Different rotational speeds of fan 1 can correspond to different blocking durations. Before the detection device detects the deformation of fan 1, it is necessary to determine the rotational speed of fan 1 and ensure that the fan reaches the set rotational speed before detecting the deformation of fan 1.

[0030] Specifically, the light emitting structure 2 can be a light-emitting diode (LED) or a laser diode. The light beam is emitted continuously or with varying pulse widths. The radiation intensity of the pulse-modulated light beam is selected multiple times during emission and travels uninterruptedly toward the light receiving structure 3. The light receiving structure 3 can be a photodiode or a phototransistor.

[0031] Specifically, the fan 1 includes fan blades. During the rotation of the fan 1, the fan blades can pass between the light emitting structure 2 and the light receiving structure 3 to block the light emitted by the light emitting structure 2. The fan blades of the fan 1 are generally injection molded from plastic materials. When the temperature of the environment where the fan 1 is located is too high, the fan blades will deform due to the high temperature, especially the area of ​​the fan blades will increase, which increases the duration of light blocking by the fan blades. The period of light received by the light receiving structure 3 changes, thus indicating that the fan blades of the fan 1 have deformed, that is, the fan 1 has deformed.

[0032] In another embodiment, the fan 1 includes fan blades and a support. The support is mounted on a preset structure, and the fan blades are rotatably mounted on the support. During the rotation of the fan 1, the fan blades can pass between the light emitting structure 2 and the light receiving structure 3 to block the light emitted by the light emitting structure 2. The support supports the fan blades, ensuring reliable rotation and facilitating the installation of the fan 1 with the preset structure. To reduce production costs, both the support and the fan blades are injection molded from plastic materials. Therefore, when the ambient temperature of the fan 1 is too high, both the fan blades and the support will deform due to the high temperature. The area of ​​the fan blades will increase, increasing the duration of light blocking and altering the period of light received by the light receiving structure 3. This indicates that the fan blades of the fan 1 have deformed, meaning the fan 1 has deformed. Similarly, the support will also deform, causing a change in the rotation axis of the fan blades, altering the duration of light blocking and changing the period of light received by the light receiving structure 3. This also indicates that the fan 1 has deformed.

[0033] The detection device further includes a comparison mechanism. This mechanism acquires the real-time time period t1 during which the fan blades block light, and compares t1 with a preset time period t0 to determine the degree of deformation of the fan 1. By comparing t1 and t0 using the comparison mechanism, the degree of deformation of the fan 1 is further determined. This allows the detection device to adjust the cooling efficiency of the refrigeration equipment based on the degree of deformation, maximizing the refrigeration capacity to meet cooling requirements while ensuring the reliability of the refrigeration equipment.

[0034] In another implementation, the detection device further includes a comparison mechanism. This mechanism acquires the real-time area S1 of the light passing through the fan blades and compares the real-time area S1 with a preset area S0 to determine the degree of deformation of the fan 1. First, the linear velocity V of the portion of the fan blade that blocks the light is determined. When the fan blade blocks the light, the blocking time is t. Within a unit time, the length of the point corresponding to the light passing through the fan blade is vt. The total length of a single fan blade passing through this point is L. The area of ​​the undeformed fan blade is Sy. The ratio of this point area to the area of ​​the undeformed fan blade is fixed at A. Since the fan blade is generally fan-shaped, the area of ​​the fan blade passing through this point within a unit time can be calculated as S1. Then, S1 is compared with the preset area S0 calculated when the fan blade is undeformed to determine the degree of deformation of the fan 1. This allows the detection device to adjust the cooling efficiency of the refrigeration equipment according to the degree of deformation, maximizing the refrigeration equipment's ability to meet cooling requirements while ensuring its reliability. By comparing area with time, the overall deformation of the fan blades can be judged, improving the accuracy of judging the degree of deformation of the fan blades, and thus improving the detection accuracy of the detection device.

[0035] Specifically, when S1≥S0≥98%S1, the comparator determines that fan 1 has undergone slight deformation and that the environment where fan 1 is located is at a high temperature. It then sends a signal to the main board of the refrigeration equipment to reduce the cooling speed. After receiving the signal, the main board issues instructions such as reducing the compressor speed to ensure that the temperature of the environment where fan 1 is located decreases slowly. When 98%S1≥S0, the comparator determines that fan 1 has undergone significant deformation and that the temperature of the environment where fan 1 is located is too high. At this time, the detection device sends a signal to suspend the refrigeration equipment to reduce the temperature of the environment where fan 1 is located and prevent fan 1 from undergoing further deformation.

[0036] The refrigeration equipment also includes a compressor, and the fan 1 is located on one side of the compressor, and the fan 1 can drive airflow through the compressor. The refrigeration equipment uses the compressor to compress the refrigerant and circulate it with the refrigerant between the evaporator and condenser for refrigeration. The compressor generates a lot of heat during operation, so the fan 1 is needed to dissipate heat from the compressor. It is also the heat from the compressor that causes the fan 1 to deform. Therefore, a detection device is set to detect the deformation of the fan 1 to ensure the reliability of the fan 1, the compressor, and the refrigeration equipment.

[0037] The refrigeration equipment also includes a housing, within which a compressor cavity is formed. Both the compressor and the fan 1 are housed within the compressor cavity. Enclosing all structures of the refrigeration equipment with the housing improves its aesthetic appearance and prevents accidental injury from accidental contact with electrical components. Furthermore, since the compressor generates heat during operation, any heat dissipating into the refrigeration cavity within the housing would affect its efficiency. Therefore, the compressor cavity is formed within the housing to house the compressor and insulate it from heat. To ensure efficient heat dissipation, the fan 1 is also housed within the compressor cavity. The detection device is also located within the compressor cavity to minimize its space occupancy within the housing.

[0038] To further improve the reliability of the refrigeration equipment, the refrigeration equipment also includes a temperature detection mechanism. This temperature detection mechanism is located inside the compressor cavity and is electrically connected to the detection device. When the detection device detects deformation of fan 1, the temperature detection mechanism detects the temperature value of the compressor cavity at this time and records this temperature value on the mainboard of the refrigeration equipment. During the next refrigeration cycle, if the temperature detection mechanism detects that the temperature inside the compressor cavity is about to reach or has already reached the previously recorded temperature value, it determines that fan 1 may have deformed. The refrigeration equipment is then controlled to reduce its cooling efficiency, effectively improving the reliability of the refrigeration equipment and fan 1. Simultaneously, the mainboard of the refrigeration equipment can also record data indicating that fan 1 has deformed or may deform, facilitating retrieval during later maintenance and improving the convenience of after-sales problem-solving.

[0039] The cooling device also includes a light-shielding structure mounted on the fan 1. When the fan 1 blocks the light emitted by the light-emitting structure 2, the light-shielding structure also blocks the light emitted by the light-emitting structure 2. This light-shielding structure improves the light-blocking effect of the fan 1, thereby increasing the detection accuracy of the detection device.

[0040] The refrigeration equipment includes a refrigerator, preferably an embedded refrigerator, including a zero-embedded refrigerator or a flat-embedded refrigerator.

[0041] A control method for the above-mentioned refrigeration equipment includes: Obtain the degree of deformation of fan 1 and compare the degree of deformation of fan 1 with the preset degree; If the deformation of fan 1 is greater than or equal to a preset level, it indicates that the ambient temperature of fan 1 is too high, and fan 1 has already deformed due to the temperature (e.g., the shape of the fan blades changes or the support of fan 1 deforms, causing a change in the rotation area of ​​the fan blades). To avoid problems such as fan 1 displacement and interference with other structures, unreliable operation, or even falling off when fan 1 or the cooling equipment continues to work, the cooling efficiency of the cooling equipment is reduced to lower the ambient temperature of fan 1 and reduce the fan speed, thereby preventing further deformation of fan 1 and ensuring the reliability of fan 1 and the cooling equipment. Reducing the cooling efficiency of the cooling equipment can reduce the heat generated by the heat-generating structure within the cooling equipment, thereby lowering the ambient temperature of fan 1. Simultaneously, due to the reduced heat generation, the required fan speed can also be reduced, thus preventing further deformation of fan 1 and ensuring the reliability of fan 1 and the cooling equipment. Since the fan blades of fan 1 deform to a certain extent due to the influence of airflow during operation, setting a preset level can eliminate the influence of airflow on the fan blades, avoiding false alarms from the detection device that could affect the normal cooling capacity of the cooling equipment.

[0042] The detection device includes a light emitting structure 2 and a light receiving structure 3. The light receiving structure 3 can receive the light emitted by the light emitting structure 2. A fan 1 is disposed between the light emitting structure 2 and the light receiving structure 3, and when the fan 1 is in operation, the fan 1 can block the light emitted by the light emitting structure 2. The preset degree includes a preset time period t0 stored in the detection device. The control method further includes: Obtain the real-time time period t1 during which fan 1 blocks the light, and compare t1 with t0; If t1 > t0, then the degree of deformation of fan 1 is determined to be greater than or equal to the preset degree. When the temperature of the environment where fan 1 is located is too high, the fan blades will deform due to the high temperature, especially the area of ​​the fan blades will increase, which increases the duration of light blocking by the fan blades. The period of light received by the light receiving structure 3 changes, thus it can be determined that the fan blades of fan 1 have deformed, that is, fan 1 has deformed.

[0043] The detection device includes a light emitting structure 2 and a light receiving structure 3. The light receiving structure 3 can receive the light emitted by the light emitting structure 2. A fan 1 is disposed between the light emitting structure 2 and the light receiving structure 3. When the fan 1 is in operation, the fan 1 can block the light emitted by the light emitting structure 2. The preset degree includes a preset area S0 stored in the detection device. The control method further includes: Obtain the real-time area S1 of the light sweeping across the fan 1, and compare S1 with S0; If S1≥S0, then the degree of deformation of fan 1 is determined to be greater than or equal to the preset degree. When the temperature of the environment where fan 1 is located is too high, the fan blades will deform due to the high temperature, especially the area of ​​the fan blades will increase, and the period of the light received by the light receiving structure 3 will change. Therefore, it can be determined that the fan blades of fan 1 have deformed, that is, fan 1 has deformed.

[0044] Specifically, after determining that the deformation degree of fan 1 is greater than or equal to the preset degree if S1≥S0, the process also includes: If S1≥S0≥98%S1, fan 1 undergoes slight deformation, and the environment where fan 1 is located has a high temperature, then the cooling efficiency of the cooling equipment is reduced. Under the premise of ensuring that the cooling equipment can cool, the temperature of the environment where fan 1 is located is slowly reduced, thereby ensuring the reliability of fan 1 and cooling equipment. If 98%S1≥S0, fan 1 has already undergone significant deformation, and the ambient temperature of fan 1 is too high. If the refrigeration equipment continues to cool at this time, there is a problem that fan 1 will undergo further deformation and interfere with or collide with other structures, and the heat-generating element will be damaged due to unreliable heat dissipation. Therefore, the refrigeration equipment is controlled to stop cooling, so that fan 1 can be sufficiently cooled down, ensuring the reliability of fan 1 and refrigeration equipment.

[0045] The refrigeration equipment further includes a compressor, a housing, and a temperature detection mechanism. The fan 1 is located on one side of the compressor and can drive airflow through the compressor. A compressor cavity is formed within the housing, and both the compressor and the fan 1 are located within the compressor cavity. The temperature detection mechanism is located within the compressor cavity and is electrically connected to the detection device. After reducing the refrigeration efficiency of the refrigeration equipment if the deformation of the fan 1 is greater than or equal to a preset level, the equipment further includes: Obtain the temperature value T of the compressor cavity when the deformation degree of fan 1 is greater than or equal to a preset degree; During the next cooling cycle of the refrigeration equipment, if the relationship between the real-time temperature value T0 of the compressor cavity and T is T>T0≥T-△T, the cooling efficiency of the refrigeration equipment is reduced. When the detection device detects deformation of fan 1, the temperature detection mechanism detects the temperature value of the compressor cavity at this time and records this temperature value on the main board of the refrigeration equipment. During the next cooling cycle, if the temperature detection mechanism detects that the temperature inside the compressor cavity is about to reach or has already reached the previously recorded temperature value, it is determined that fan 1 may have deformed, and the refrigeration equipment is controlled to reduce the cooling efficiency, effectively improving the reliability of the refrigeration equipment and fan 1. At the same time, the main board of the refrigeration equipment can also record data on whether fan 1 has deformed or may deform, which is convenient to read during later maintenance and improves the convenience of after-sales problem solving. The value range of △T is 2℃ to 10℃, preferably 5℃.

[0046] The refrigeration equipment further includes a compressor, a housing, and a temperature detection mechanism. The fan 1 is located on one side of the compressor and can drive airflow through the compressor. A compressor cavity is formed within the housing, and both the compressor and the fan 1 are located within the compressor cavity. The temperature detection mechanism is located within the compressor cavity and is electrically connected to the detection device. After reducing the refrigeration efficiency of the refrigeration equipment if the deformation of the fan 1 is greater than or equal to a preset level, the equipment further includes: Obtain the temperature value T of the compressor cavity when the deformation degree of fan 1 is greater than or equal to a preset degree; During the next cooling process of the refrigeration equipment, if the relationship between the real-time temperature value T0 of the compressor cavity and T is T0≥T, it can be determined that the fan 1 has been deformed and the refrigeration equipment cannot work normally. In this case, the refrigeration equipment is prompted to be malfunctioning and / or a suggestion to replace the fan 1 is given.
