The refrigeration equipment further includes a sealing structure for sealing the connection between the box body air outlet and the unit air inlet, and the connection between the unit air outlet and the box body air inlet. The temperature difference between the inside and outside of the sealing structure is relatively large, and condensation is likely to occur on the outer side wall of the sealing structure. The formed water droplets may flow down to the electrical components of the refrigeration unit, causing potential safety hazards. Therefore, it is necessary to prevent the formation of condensation at the sealing structure.

[0046] In a first aspect, an embodiment of the present disclosure provides a refrigeration device.

[0047] Combined with Figure 1 As shown, the refrigeration device provided by the embodiment of the present disclosure includes a box body 100, a refrigeration unit 200, a sealing structure 300, and an identification component.

[0048] The box body 100 includes a storage cavity 101 and a box body vent 102, and the box body vent 102 communicates with the storage cavity 101. Among them, the box body 100 includes one or more box body vents 102.

[0049] The refrigeration unit 200 includes an evaporator chamber 201 and a unit vent 202. The evaporator chamber 201 communicates with the unit vent 202, and the unit vent 202 correspondingly communicates with the box body vent 102. The refrigeration unit 200 includes one or more unit vents 202, and the unit vents 202 correspond to the box body vents 102 one by one.

[0050] The sealing structure 300 is provided at the connection between the box body vent 102 and the unit vent 202.

[0051] The identification component is used to detect the distance between the box body vent 102 and the unit vent 202 to obtain the extrusion degree of the sealing structure 300.

[0052] For the refrigeration device provided by the embodiment of the present disclosure, the box body vent 102 and the unit vent 202 are communicated. By providing a sealing structure at the connection between the box body vent 102 and the unit vent 202, the sealed connection between the evaporator chamber 201 and the storage cavity 101 can be realized. The air flow in the storage cavity 101 flows through the evaporator chamber 201, cools down in the evaporator chamber 201 and then returns to the storage cavity 101 again, realizing the refrigeration cycle between the refrigeration unit 200 and the box body 100. By detecting the distance between the box body vent 102 and the unit vent 202 through the identification component, the extrusion degree of the sealing structure can be obtained, and thus the sealing effect of the sealing structure can be obtained according to the extrusion degree of the sealing structure. In this way, the accuracy of judging the sealing effect can be improved, and thus the accuracy of the temperature in the storage cavity 101 can be improved.

[0053] It can be understood that the box body vent 102 is provided on the first box wall of the box body 100, and the unit vent 202 is provided on the first unit wall of the refrigeration unit 200. Among them, the distance between the box body vent 102 and the unit vent 202 is also the distance between the first box wall and the first unit wall.

[0054] In some embodiments, as shown in Figure 2 and Figure 3 a first magnetic strip 301 is provided inside the sealing structure 300, and the first magnetic strip 301 is located on the first side of the box body vent 102. The identification component includes a first sensor 401. The first sensor 401 is provided on the box body 100 and is located on the first side of the box body vent 102. The first sensor 401 is used to detect the first distance between the first side of the box body vent and the first magnetic strip 301.

[0055] By arranging a first magnetic strip 301 inside the sealing structure 300, the first sensor 401 detects the first distance between the first sensor 401 and the first magnetic strip 301, and the distance between the cabinet ventilation opening 102 and the unit ventilation opening 202 can be calculated, thereby obtaining the extrusion degree of the sealing structure 300. In addition, the first magnetic strip is attracted to the first cabinet wall and the first unit wall, which helps to enhance the sealing performance of the sealing structure 300.

[0056] Optionally, the first magnetic strip 301 is arranged in the middle of the sealing structure. That is to say, the distance between the first magnetic strip 301 and the upper surface of the sealing structure is equal to the distance between the first magnetic strip 301 and the lower surface of the sealing structure. With such an arrangement, it is convenient to calculate the distance between the cabinet ventilation opening 102 and the unit ventilation opening 202 through the first distance h 1 , and the distance between the cabinet ventilation opening 102 and the unit ventilation opening 202 is 2h 1 .

[0057] In some embodiments, as shown in combination with Figure 3 and Figure 4 , the recognition component further includes a second sensor 402. The second sensor 402 is arranged on the cabinet 100 and is located on the second side of the cabinet ventilation opening 102. The second sensor 402 is used to detect the second distance h between the second side of the cabinet ventilation opening 102 and the first magnetic strip 301 2 . The second side of the cabinet ventilation opening 102 is arranged opposite to the first side of the cabinet ventilation opening 102.

[0058] By measuring the first distance h 1 and the second distance h 2 , the distance l between the second sensor 402 and the first magnetic strip 301 can be calculated 1 , thereby obtaining the offset distance of the sealing structure in the first direction, which is convenient for inferring the sealing effect of the sealing structure according to the offset distance, further improving the accuracy of judging the sealing effect, and improving the accuracy of the temperature in the storage cavity 101. Among them, the first direction is parallel to the straight line where the first sensor 401 and the second sensor 402 are located.

[0059] In some embodiments, a second magnetic strip is further arranged inside the sealing structure 300. The second magnetic strip is located on the third side of the cabinet ventilation opening 102, and the third side of the cabinet ventilation opening 102 is adjacent to the first side of the cabinet ventilation opening 102. The recognition component includes a third sensor. The third sensor is arranged on the cabinet 100 and is located on the third side of the cabinet ventilation opening 102. The third sensor is used to detect the third distance between the third side of the cabinet ventilation opening 102 and the second magnetic strip.

[0060] With such a setting, the third sensor can detect the distance between the third side of the box vent 102 and the second magnetic strip, and the distance between another box vent 102 and the unit vent 202 can be calculated. Through the multiple calculated distances, the average distance between the box vent 102 and the unit vent 202 can be calculated, improving the accuracy of judging the extrusion degree of the sealing structure 300.

[0061] In some embodiments, the recognition component further includes a fourth sensor. The fourth sensor is disposed on the box body 100 and is located on the fourth side of the box vent 102. The fourth sensor is used to detect the fourth distance between the fourth side of the box vent 102 and the second magnetic strip. The fourth side of the box vent 102 is disposed opposite to the third side of the box vent 102.

[0062] Through the third distance and the fourth distance, the distance between the fourth sensor and the second magnetic strip can be calculated, thereby obtaining the offset distance of the sealing structure in the second direction, facilitating the inference of the sealing effect of the sealing structure according to the offset distance, further improving the accuracy of judging the sealing effect, and improving the accuracy of the temperature in the storage cavity 101. Wherein, the second direction is parallel to the straight line where the third sensor and the fourth sensor are located.

[0063] In some embodiments, one or more of the first sensor 401, the second sensor 402, the third sensor, and the fourth sensor are Hall sensors. A Hall sensor is a magnetic sensor based on the Hall effect. It can sense the magnetic field and magnetic field changes and is usually composed of a Hall element and an accessory circuit. The Hall element is made of semiconductor material and has the advantages of being sensitive to magnetic fields, simple structure, small volume, wide frequency response, large output voltage change, and long service life.

[0064] Optionally, the first sensor 401, the second sensor 402, the third sensor, and the fourth sensor are all Hall sensors. The Hall sensors cooperate with the magnetic strips to realize the measurement of the position of the sealing structure.

[0065] In some embodiments, a third magnetic strip is further disposed inside the sealing structure 300. The third magnetic strip is located on the second side of the box vent 102. By providing the third magnetic strip, it is convenient to measure the distance between the second side of the box vent 102 and the second side of the unit vent, so that the accuracy of judging the extrusion degree and offset distance of the sealing structure 300 can be improved.

[0066] In some embodiments, a fourth magnetic strip is further disposed inside the sealing structure 300. The fourth magnetic strip is located on the fourth side of the box vent 102. By providing the fourth magnetic strip, it is convenient to measure the distance between the fourth side of the box vent 102 and the fourth side of the unit vent, so that the accuracy of judging the extrusion degree and offset distance of the sealing structure 300 can be improved.

[0067] In some embodiments, in combination with Figure 5 and Figure 6 As shown, the cabinet vent 102 includes a cabinet air inlet 1021 and a cabinet air outlet 1022, and the unit vent 202 includes a unit air inlet 2021 and a unit air outlet 2022. The cabinet air inlet 1021 communicates with the unit air outlet 2022, and the cabinet air outlet 1022 communicates with the unit air inlet 2021. A sealing structure 300 is provided between the cabinet air inlet 1021 and the unit air outlet 2022, and between the cabinet air outlet 1022 and the unit air inlet 2021.

[0068] By providing a sealing structure between the cabinet air inlet 1021 and the unit air outlet 2022, the cabinet air inlet 1021 and the unit air outlet 2022 can be hermetically connected. By providing a sealing structure 300 between the cabinet air outlet 1022 and the unit air inlet 2021, the cabinet air outlet 1022 and the unit air inlet 2021 can be hermetically connected. In this way, the air flow in the storage cavity 101 flows through the evaporator chamber 201, cools down in the evaporator chamber 201, and then returns to the storage cavity 101, realizing the refrigeration cycle between the refrigeration unit 200 and the cabinet 100.

[0069] In some embodiments, the sealing structure 300 includes a sealing strip, and the sealing strip is disposed around the circumferences of the cabinet vent 102 and the unit vent 202. The sealing strip includes a first sealing strip on the first side of the cabinet vent 102, and a first magnetic strip 301 is provided inside the first sealing strip. The sealing strip includes a second sealing strip on the third side of the cabinet vent 102, and a second magnetic strip is provided inside the second sealing strip. The sealing strip includes a third sealing strip on the second side of the cabinet vent 102, and a third magnetic strip is provided inside the third sealing strip. The sealing strip includes a fourth sealing strip on the fourth side of the cabinet vent, and a fourth magnetic strip is provided inside the fourth sealing strip.

[0070] In some embodiments, in combination with Figure 1 As shown, the refrigeration unit 200 is disposed below the cabinet 100. With this arrangement, during the assembly of the refrigeration unit 200, by designing a lifting frame below the cabinet 100, the refrigeration unit 200 is placed on the lifting frame, the positions of the refrigeration unit 200 and the cabinet 100 correspond to each other, and then the lifting frame is lifted to hermetically connect the cabinet 100 and the refrigeration unit 200.

[0071] In some embodiments, in combination with Figure 2 and Figure 4As shown, the refrigeration device further includes one or more heating elements 500. The heating element 500 is disposed at the outer edge of the sealing structure 300, and the heating element 500 is used to heat the sealing structure 300 to alleviate the condensation of the sealing structure 300. Under the influence of the temperature difference between the inside and outside of the sealing structure 300 and the external humid and hot air, condensation is likely to occur on the outer side of the sealing structure. By providing a heating element at the outer edge of the sealing structure and using the heating element to heat the sealing structure, the condensation of the sealing structure can be removed.

[0072] Optionally, the heating element 500 is a heating wire or a refrigeration heat pipe.

[0073] In some embodiments, in combination with Figure 1 As shown, the evaporator chamber 201 is provided with an evaporator 2011 and an evaporation fan 2012. The rotation of the evaporation fan 2012 causes the air flow to flow between the storage cavity 101 and the evaporator chamber 201, realizing the refrigeration cycle between the refrigeration unit 200 and the box body 100. The refrigerant in the evaporator 2011 evaporates and absorbs heat in the evaporator 2011, reducing the surface temperature of the evaporator 2011. After the air flow passes through the surface of the evaporator 2011, the temperature decreases, and then it flows to the storage cavity 101, reducing the temperature of the storage cavity 101.

[0074] In some embodiments, in combination with Figure 1 As shown, the refrigeration unit 200 further includes a compressor chamber 203. A compressor, a condenser, and a condensation fan are disposed in the compressor chamber 203. Structures such as the compressor, the condenser, and the evaporator cooperate to form a refrigerant circulation loop, reducing the temperature of the evaporator and providing cold for the storage cavity 101. The condensation fan is used to accelerate the air flow on the surface of the condenser to dissipate heat for the condenser.

[0075] In some embodiments, in combination with Figure 1 As shown, the refrigeration unit 200 further includes a heat insulation layer 600. The heat insulation layer 600 is disposed between the evaporator chamber 201 and the compressor chamber 203. The heat insulation layer 600 can separate the evaporator chamber 201 from the compressor chamber 203, reducing the influence of the compressor chamber 203 on the evaporator chamber 201 and ensuring the refrigeration effect of the refrigeration device.

[0076] Optionally, the heat insulation layer material includes one or more of foam, foaming material, and VIP material (vacuum insulation panel). The materials in the embodiments of the present disclosure all have good heat insulation effects and can all achieve heat insulation for the evaporator chamber 201.

[0077] In a second aspect, the embodiments of the present disclosure provide a method for controlling a refrigeration device, which is used to adjust the rotation speed of the compressor and the rotation speed of the evaporation fan to meet the refrigeration requirements of the refrigeration device.

[0078] In combination with Figure 7As shown, the method for controlling a refrigeration device includes:

[0079] S101, the refrigeration device detects the distance between the cabinet ventilation opening and the unit ventilation opening.

[0080] S102, when the distance between the cabinet ventilation opening and the unit ventilation opening is greater than a preset distance threshold and less than a first distance threshold, the refrigeration device adjusts the rotational speed of the compressor and the rotational speed of the evaporation fan according to the distance between the cabinet ventilation opening and the unit ventilation opening to meet the refrigeration demand of the refrigeration device.

[0081] Due to the influence of production and manufacturing processes, such as cabinet foaming and factory assembly, there are certain differences in the distance between the cabinet of the refrigeration device and the refrigeration unit, and there are certain differences in the extrusion degree of the sealing structure. Due to the large temperature difference between the inside and outside of the sealing structure, the sealing structure needs to meet a certain extrusion degree to ensure a good sealing effect. If the extrusion degree of the sealing structure is too small, it will cause a certain degree of cold leakage. The method for controlling a refrigeration device provided by the embodiments of the present disclosure can judge the extrusion degree of the sealing structure according to the distance between the cabinet ventilation opening and the unit ventilation opening, and adjust the rotational speed of the compressor and the rotational speed of the evaporation fan according to the extrusion degree of the sealing structure, so that the refrigeration device can cool down quickly, improve the accuracy of the temperature of the refrigeration device, and meet the refrigeration demand of the refrigeration device.

[0082] The distance between the cabinet ventilation opening and the unit ventilation opening is greater than a preset distance threshold and less than a first distance threshold, that is, D 0 <h<D 1 . Wherein, h is the distance between the cabinet ventilation opening and the unit ventilation opening, D 0 is the preset distance threshold, and D 1 is the first distance threshold.

[0083] Optionally, the preset distance threshold is an optimal distance threshold. When D 2 <h≤D 0 , the sealing effect of the sealing structure can meet the refrigeration demand of the cabinet.

[0084] Optionally, when h≤D 2 , the refrigeration device alarms to prompt that the sealing structure is abnormal, D 2 <D 0 . When h≤D 2 , the distance between the cabinet ventilation opening and the unit ventilation opening is too small, and the extrusion degree of the sealing structure is too large, that is, the extrusion degree of the sealing structure is close to or exceeds the maximum extrusion degree allowed by the sealing structure, which will cause damage to the sealing structure and affect the sealing performance of the cabinet. Therefore, the refrigeration device alarms to prompt that the sealing structure is abnormal and repairs the sealing structure in time.

[0085] Optionally, when h≥D1 In this case, the refrigeration equipment alarms to indicate an abnormal sealing structure. When h ≥ D 1 In this case, the distance between the cabinet ventilation opening and the unit ventilation opening is too large, and the extrusion degree of the sealing structure is too small. As a result, the cold leakage of the sealing structure is too large to meet the airtightness of the cabinet. Therefore, the refrigeration equipment alarms to indicate an abnormal sealing structure, and the sealing structure is repaired in time.

[0086] For example, when not under extrusion, the thickness of the sealing structure is 12 mm, D 0 is 8 mm, D 2 is 5 mm, D 1 is 10 mm.

[0087] In some embodiments, the refrigeration equipment detects the distance between the cabinet ventilation opening and the unit ventilation opening, including: the refrigeration equipment obtains a first distance between the first magnetic strip and the first side of the cabinet ventilation opening. The refrigeration equipment determines the distance between the cabinet ventilation opening and the unit ventilation opening according to the first distance. With this setting, the distance between the cabinet ventilation opening and the unit ventilation opening can be obtained more accurately.

[0088] For example, the first magnetic strip 301 is arranged in the middle of the sealing structure, and the first distance is h 1 , and the distance between the cabinet ventilation opening 102 and the unit ventilation opening 202 is equal to 2h 1 .

[0093] By using the method for controlling a refrigeration equipment provided by an embodiment of the present disclosure, the distance between the cabinet ventilation opening and the unit ventilation opening can be obtained more accurately.

[0094] Combined with Figure 9As shown, an embodiment of the present disclosure provides another method for controlling a refrigeration device, which is used to illustrate how to adjust the rotational speed of a compressor and the rotational speed of an evaporation fan according to the distance between a cabinet ventilation opening and a unit ventilation opening.

[0103] Optionally, the refrigeration device determines a target adjustment amount of the rotational speed of the compressor corresponding to the current distance difference according to a positive correlation between the distance difference and an adjustment amount of the rotational speed of the compressor, including: when Δd 1 <Δh<Δd 2 the target adjustment amount of the rotational speed of the compressor is determined to be n 1 . When Δd 2 ≤Δh<Δd 3 the target adjustment amount of the rotational speed of the compressor is determined to be n 2 . Wherein, Δh = h - D 0 , Δh is the current distance difference, h is the distance between the cabinet ventilation opening and the unit ventilation opening, D 0 is the preset distance threshold, Δd 1 is the first distance difference, Δd 2is the second distance difference, Δd 3 is the second distance difference, Δd 1 <Δd 2 <Δd 3 , n 1 <n 2 .

[0108] S402, the refrigeration device determines the distance between the ventilation opening of the box body and the ventilation opening of the unit according to the first distance

[0109] S403, the refrigeration device obtains the current distance difference between the distance between the ventilation opening of the box body and the ventilation opening of the unit and the preset distance threshold

[0113] S407. When Δd 2 ≤Δh<Δd 3 determine the target adjustment amount of the evaporator fan speed to be m 2 .

[0114] S408. The refrigeration equipment adjusts the speeds of the compressor and the evaporator fan according to the target adjustment amounts of the compressor speed and the evaporator fan speed.

[0115] When Δd 1 <Δh<Δd 2 the leakage cooling amount of the sealing structure is relatively small, and the speed of the compressor is increased by n 1 rps, which can increase the refrigeration capacity, make up for the leakage cooling amount at the sealing structure, and ensure that the refrigeration equipment cools quickly. When Δd 2 ≤Δh<Δd 3 the leakage cooling amount of the sealing structure is relatively large, and the speed of the compressor is increased by n 2 rps, which can further increase the refrigeration capacity, make up for the leakage cooling amount at the sealing structure, ensure that the refrigeration equipment cools quickly, and avoid frequent start-stop.

[0116] When Δd 1 <Δh<Δd 2 the leakage cooling amount of the sealing structure is relatively small, and the speed of the evaporator fan is increased by m 1 rpm, which can increase the refrigeration capacity, make up for the leakage cooling amount at the sealing structure, and ensure that the refrigeration equipment cools quickly. When Δd 2 ≤Δh<Δd 3 the leakage cooling amount of the sealing structure is relatively large, and the speed of the evaporator fan is increased by m 2 rpm, which can further increase the refrigeration capacity, make up for the leakage cooling amount at the sealing structure, ensure that the refrigeration equipment cools quickly, and avoid frequent start-stop.

[0117] For example, when h ≤ D 0 the rotational speed of the compressor is 3800 rpm, and the rotational speed of the evaporation fan is 1600 rpm. Δd 1 is 0 mm, Δd 2 is 2 mm, Δd 3 is 4 mm. When 0 mm < Δh < 2 mm, the rotational speed of the compressor is 4000 rpm, and the rotational speed of the evaporation fan is 1800 rpm. When 2 mm ≤ Δh < 4 mm, the rotational speed of the compressor is 4200 rpm, and the rotational speed of the evaporation fan is 2000 rpm.

[0118] RPM is the abbreviation of Revolution Per Minute in English, which refers to the number of revolutions per minute. RPS is the abbreviation of Revolution Per Second in English, which refers to the number of revolutions per second.

[0119] By using the method for controlling a refrigeration device provided in the embodiment of the present disclosure, the rotational speeds of the compressor and the evaporation fan can be adaptively adjusted according to the cold leakage amount at the sealing structure, the cold leakage amount at the sealing structure can be compensated, rapid refrigeration of the refrigeration device can be ensured, and frequent start-stop can be avoided.

[0120] Combined with Figure 11 as shown, the embodiment of the present disclosure provides another method for controlling a refrigeration device, including:

[0121] S501, the refrigeration device obtains a first distance between a first magnetic strip and a first side of a box body ventilation opening.

[0122] S502, the refrigeration device determines a distance between the box body ventilation opening and the unit ventilation opening according to the first distance.

[0123] S503, the refrigeration device obtains a current distance difference between the distance between the box body ventilation opening and the unit ventilation opening and a preset distance threshold.

[0124] S504, the refrigeration device determines a target adjustment amount of the rotational speed of the compressor corresponding to the current distance difference according to a positive correlation relationship between the distance difference and the adjustment amount of the rotational speed of the compressor.

[0125] S505, the refrigeration device determines a target adjustment amount of the rotational speed of the evaporation fan corresponding to the current distance difference according to a positive correlation relationship between the distance difference and the adjustment amount of the rotational speed of the evaporation fan.

[0126] S506, the refrigeration device adjusts the rotational speed of the compressor and the rotational speed of the evaporation fan according to the target adjustment amount of the rotational speed of the compressor and the target adjustment amount of the rotational speed of the evaporation fan.

[0127] S507, the refrigeration device obtains an offset area of the sealing structure.

[0128] S508, when in △S 1 <△S<△S 2 the refrigeration device controls the rotational speeds of the compressor and the evaporation fan to increase.

[0129] Ideally, the sealing structure is arranged to surround the circumferential direction of the ventilation opening of the box body. However, during the assembly process of the refrigeration device, there may be a certain deviation in the sealing structure, thus blocking the ventilation opening of the box body. In the embodiments of the present disclosure, by obtaining the deviation area of the sealing structure and adjusting the rotational speeds of the compressor and the evaporation fan according to the deviation area, the influence caused by the blockage of the ventilation opening of the box body can be compensated, ensuring that the storage cavity of the refrigeration device is quickly cooled and meeting the refrigeration requirements of the refrigeration device.

[0130] When in △S 1 <△S<△S 2 the deviation area of the sealing structure is relatively small. The refrigeration device controls the rotational speeds of the compressor and the evaporation fan to increase, which can increase the refrigerating capacity, make up for the cold leakage at the sealing structure, and ensure that the refrigeration device is quickly cooled.

[0131] S509, when △S≥△S 2 the refrigeration device gives an alarm to indicate that the deviation area of the sealing structure is too large.

[0132] When △S2≤△S, the deviation area of the sealing structure is relatively large, which will not only block the ventilation opening of the box body but also affect the sealing effect. The refrigeration device gives an alarm to indicate that the deviation area of the sealing structure is too large, and the sealing structure is repaired in time.

[0133] The method for controlling the refrigeration device provided by the embodiments of the present disclosure can judge the extrusion degree of the sealing structure according to the distance between the ventilation opening of the box body and the ventilation opening of the unit, and adjust the rotational speeds of the compressor and the evaporation fan according to the extrusion degree of the sealing structure, so that the refrigeration device can quickly cool down, improve the accuracy of the temperature of the refrigeration device, and meet the refrigeration requirements of the refrigeration device. In addition, according to the cold leakage situation of the sealing structure, the condensation situation of the sealing structure can be obtained, and thus the heating power of the heating element can be adaptively adjusted, which can quickly remove the condensation at the sealing structure and reduce the safety hazard.

[0134] In the embodiments of the present disclosure, the adjustment of the rotational speeds of the compressor and the evaporation fan is a superposition based on "adjusting the rotational speeds of the compressor and the evaporation fan according to the distance between the ventilation opening of the box body and the ventilation opening of the unit". In this way, two factors, namely the deviation area of the sealing structure and the current distance difference of the sealing structure, are considered, which is beneficial to improving the accuracy of the adjustment of the rotational speeds of the compressor and the evaporation fan and meeting the refrigeration requirements of the refrigeration device.

[0135] Optionally, 0≤△S 1 <1 / 10S0 , 1 / 5S 0 ≤△S 2 ≤1 / 3S 0 , S 0 is the area of the sealing structure. For example, △S 1 is 0, △S 2 is 1 / 3S 0 , when 0 < △S < 1 / 3S 0 , the refrigeration equipment controls the rotational speeds of the compressor and the evaporation fan to increase. When 1 / 3S 0 ≤△S, the refrigeration equipment gives an alarm to indicate that the offset area of the sealing structure is too large.

[0136] In some embodiments, as shown in combination with Figure 12 , obtaining the offset area of the sealing structure includes: the refrigeration equipment detects a first offset length △L of the sealing structure along the width direction of the ventilation opening of the box body 1 . The refrigeration equipment detects a second offset length △L of the sealing structure along the length direction of the ventilation opening of the box body 2 . According to the following formula, the offset area of the sealing structure is calculated as:

[0137] ΔS = ΔL 1 ×2H 1 +ΔL 2 ×2H 2 ;

[0138] In the formula, ΔS is the offset area of the sealing structure, ΔL 1 is the first offset length, H 1 is the length of the sealing structure, ΔL 2 is the second offset length, H 2 is the width of the sealing structure.

[0139] With such a setting, the offset area of the sealing structure can be obtained more accurately, and then the matching condition between the sealing structure and the ventilation opening of the box body can be judged according to the offset area of the sealing structure.

[0140] Combined with the above embodiments, the first sensor 401 is used to detect a first distance h between the first side of the ventilation opening of the box body and the first magnetic strip 301 1 . The second sensor 402 is used to detect a second distance h between the second side of the ventilation opening 102 of the box body and the first magnetic strip 301 2 . Through the first distance h 1 , the second distance h 2 and the Pythagorean theorem, the distance l between the second side of the ventilation opening 102 of the box body and the first magnetic strip 301 can be calculated 1 . Using l 1 -l 0The first offset length ΔL in the width direction of the box body ventilation opening 102 can be obtained. 1 , where l 0 refers to the preset distance between the second side of the box body ventilation opening 102 and the first magnetic strip 301.

[0141] The third sensor is used to detect the third distance between the third side of the box body ventilation opening 102 and the second magnetic strip. The fourth sensor is used to detect the fourth distance between the fourth side of the box body ventilation opening 102 and the second magnetic strip. Through the third distance, the fourth distance and the Pythagorean theorem, the distance between the fourth side of the box body ventilation opening 102 and the second magnetic strip can be calculated. Subtracting the preset distance between the fourth side of the box body ventilation opening 102 and the second magnetic strip from this distance, the second offset length ΔL in the length direction of the box body ventilation opening 102 can be obtained. 2 .

[0142] In a third aspect, an embodiment of the present disclosure provides another method for controlling a refrigeration device, which is used to adjust the heating power of a heating element to improve the effect of removing condensation of a sealing structure.

[0143] As shown in combination with Figure 14 , the method for controlling the refrigeration device includes:

[0144] S601, the refrigeration device obtains the distance between the box body ventilation opening and the unit ventilation opening.

[0145] The distance between the box body ventilation opening and the unit ventilation opening affects the extrusion degree of the sealing structure. Through the cooperation of the above-mentioned first sensor and the first magnetic strip, the distance between the box body ventilation opening and the unit ventilation opening can be detected.

[0146] S602, the refrigeration device obtains the offset area of the sealing structure relative to the box body ventilation opening.

[0147] When the position of the sealing structure relative to the box body ventilation opening is different, the offset area of the sealing structure will be different.

[0148] S603, the refrigeration device determines the offset volume of the sealing structure according to the distance between the box body ventilation opening and the unit ventilation opening and the offset area.

[0149] Due to the influence of production and manufacturing processes, such as box body foaming and factory assembly, etc., there are certain differences in the extrusion degree of the sealing structure and the position of the sealing structure relative to the box body ventilation opening, resulting in a certain offset volume of the sealing structure. Through the offset volume of the sealing structure, the cold leakage amount of the sealing structure can be more intuitively judged. The larger the offset volume of the sealing structure, the worse the sealing effect and the relatively more cold leakage. The smaller the offset volume of the sealing structure, the better the sealing effect and the relatively less cold leakage.

[0150] S604. The refrigeration device determines the heating power of the heating element according to the offset volume of the sealing structure.

[0151] The sealing structure mainly includes rubber and an internal airbag, which is used to block the leakage of cold air inside the refrigeration device. The heat preservation performance of the sealing structure is poor, so the temperature difference between the inside and outside of the sealing structure is relatively large. When the external environmental temperature of the refrigeration device is 30°C and the temperature inside the box of the refrigeration device is -18°C, the outside of the sealing structure contacts the humid and hot air, and condensation will form on the outside of the sealing structure. The water droplets formed by the condensation may flow down to the electrical components of the refrigeration unit, causing potential safety hazards. Therefore, it is necessary to heat the sealing structure to remove the condensation at the sealing structure. The method for controlling a refrigeration device provided by the embodiments of the present disclosure can judge the cold leakage situation of the sealing structure according to the offset volume of the sealing structure, and adjust the heating power of the heating element according to the cold leakage situation of the sealing structure. Adjusting the heating power of the heating element according to the cold leakage situation of the sealing structure can alleviate problems such as excessive heat or insufficient heat of the heating element, thereby being beneficial to improving the effect of removing condensation from the sealing structure.

[0152] Combined with Figure 17 As shown, the embodiments of the present disclosure provide another method for controlling a refrigeration device, including:

[0153] S901. The refrigeration device obtains the distance between the box ventilation opening and the unit ventilation opening.

[0154] S902. The refrigeration device obtains the first distance h between the first magnetic strip and the first side of the box ventilation opening 1 .

[0155] S903. The refrigeration device obtains the second distance h between the first magnetic strip and the second side of the box ventilation opening 2 . The second side of the box ventilation opening and the first side of the box ventilation opening are arranged opposite to each other along the width direction of the box ventilation opening.

[0156] S904. The refrigeration device calculates the current distance between the first magnetic strip and the second side of the box ventilation opening according to the first distance and the second distance.

[0157] S905. The refrigeration device calculates ΔL 1 =|l 1 -l 0 | to determine the first offset length ΔL 1 . In the formula, ΔL 1 is the first offset length, l 1 is the current distance between the first magnetic strip and the second side of the box ventilation opening, and l 0 is the preset distance between the first magnetic strip and the second side of the box ventilation opening. In this way, the first offset length of the refrigeration device detecting the sealing structure along the width direction of the box ventilation opening can be obtained.

[0158] Combined with Figure 4 it can be seen that by substituting the first distance h 1 and the second distance h 2 into the Pythagorean theorem to calculate h 2 2 -h 1 2 the value of l can be obtained 1 . Since the sealing structure may shift in the direction away from the second side of the box body vent or in the direction towards the second side of the box body vent, the absolute value of the difference between l 1 and l 2 is taken as the first offset length. By adopting the above method, the first offset length can be calculated.

[0159] S906. The refrigeration device detects the second offset length ΔL of the sealing structure along the length direction of the box body vent 2 .

[0160] Optionally, for the refrigeration device to detect the second offset length ΔL of the sealing structure along the length direction of the box body vent 2 , it includes: the refrigeration device obtains the third distance h between the second magnetic strip and the third side of the box body vent 3 . The refrigeration device obtains the fourth distance h between the second magnetic strip and the fourth side of the box body vent 4 , and the fourth side and the third side of the box body vent are arranged opposite to each other along the length direction of the box body vent. The refrigeration device calculates the current distance l between the second magnetic strip and the fourth side of the box body vent according to the third distance and the fourth distance 2 . The refrigeration device calculates ΔL 2 =|l 2 -l 00 | to determine the second offset length. In the formula, ΔL 2 is the second offset length, l 2 is the current distance between the second magnetic strip and the fourth side of the box body vent, and l 00 is the preset distance between the second magnetic strip and the fourth side of the box body vent.

[0161] By adopting the above method, the second offset length can be calculated.

[0162] S907. The refrigeration device calculates ΔS = ΔL 1 ×2H 1 +ΔL 2 ×2H 2 to determine the offset area ΔS of the sealing structure.

[0163] Here, the refrigeration device detects the first offset length of the sealing structure along the width direction of the box body ventilation opening, and the second offset length of the sealing structure along the length direction of the box body ventilation opening. Calculate ΔS = ΔL 1 ×2H 1 +ΔL 2 ×2H 2 , to determine the offset area ΔS of the sealing structure. In the formula, ΔS is the offset area of the sealing structure, and ΔL 1 is the first offset length, and H 1 is the length of the sealing structure, and ΔL 2 is the second offset length, and H 2 is the width of the sealing structure.

[0164] ΔL 1 reflects the offset amount of the sealing structure along the width direction of the box body ventilation opening, and ΔL 2 reflects the offset amount of the sealing structure along the length direction of the box body ventilation opening. In this way, the offset area of the sealing structure can be obtained more accurately, and then the matching situation between the sealing structure and the box body ventilation opening can be judged according to the offset area of the sealing structure.

[0165] S908, the refrigeration device obtains the current distance difference between the distance between the box body ventilation opening and the unit ventilation opening and the preset distance threshold.

[0166] S909, the refrigeration device calculates ΔV = ΔS × Δh to determine the offset volume ΔV of the sealing structure. In the formula, ΔS is the offset area of the sealing structure, Δh is the current distance difference, and Δh = h - D 0 , where h is the distance between the box body ventilation opening and the unit ventilation opening, and D 0 is the preset distance threshold.

[0167] The current distance difference of the sealing structure reflects the gap between the extrusion degree of the sealing structure and the target extrusion degree, and the offset area of the sealing structure reflects the offset situation of the position of the sealing structure relative to the box body ventilation opening. When the position and extrusion degree of the sealing structure change, the cold leakage amount of the sealing structure will change. In the embodiments of the present disclosure, by two factors of the offset area and the current distance difference, the cold leakage situation of the sealing structure is comprehensively judged, which is beneficial to improving the accuracy of judging the cold leakage situation of the sealing structure.

[0168] S910, the refrigeration device determines the heating power of the heating element according to the offset volume of the sealing structure.

[0169] The method for controlling a refrigeration device provided by the embodiments of the present disclosure comprehensively judges the cold leakage situation of the sealing structure through two factors of the offset area and the current distance difference, which is beneficial to improving the accuracy of judging the cold leakage situation of the sealing structure.

[0170] In some embodiments, the refrigeration device determines the heating power of the heating element according to the offset volume of the sealing structure (step S604), including: the refrigeration device determines the adjustment scheme of the heating element according to the correlation between the offset volume and the heating power of the heating element. The refrigeration device controls the operation of the heating element according to the adjustment scheme of the heating element.

[0171] The larger the offset volume of the sealing structure, the more serious the cold leakage at the sealing structure, and the more serious the condensation at the sealing structure. Through the correlation between the offset volume and the heating power of the heating element, the heating power adapted to the cold leakage situation of the sealing structure can be determined, the generation of condensation at the sealing structure can be prevented, and the safety hazard can be reduced.

[0172] Combined Figure 15 As shown, the embodiment of the present disclosure provides another method for controlling a refrigeration device, including:

[0173] S701, the refrigeration device obtains the distance between the box ventilation opening and the unit ventilation opening.

[0174] S702, the refrigeration device obtains the offset area of the sealing structure relative to the box ventilation opening.

[0175] S703, the refrigeration device determines the offset volume of the sealing structure according to the distance between the box ventilation opening and the unit ventilation opening and the offset area.

[0176] S704, when 0 ≤ ΔV < ΔV 1 , the adjustment scheme of the heating element is that the heating element operates at a heating power of p 1 W.

[0177] S705, when ΔV 1 ≤ ΔV < ΔV 2 , the adjustment scheme of the heating element is that the heating element operates at a heating power of p 2 W.

[0178] S706, when ΔV 2 ≤ ΔV < ΔV 3 , the adjustment scheme of the heating element is that the heating element operates at a heating power of p 3 W. Wherein, ΔV 1 is the first volume threshold, ΔV 2 is the second volume threshold, ΔV 3 is the third volume threshold, ΔV 1 < ΔV 2 < ΔV 3 , p 1 is the first power threshold, p 2 is the second power threshold, p 3is the third power threshold, p 1 <p 2 <p 3 。

[0179] S707, the refrigeration device controls the operation of the heating element according to the adjustment scheme of the heating element.

[0180] By changing the voltage of the heating element, the power of the heating element can be changed. When 0 ≤ ΔV < ΔV 1 , the cold leakage of the sealing structure is relatively small, the condensation at the sealing structure is relatively light, and the heating power of the heating element is p 1 W, which can quickly remove the condensation at the heating element and reduce the impact on the temperature inside the refrigeration device. When ΔV 1 ≤ ΔV < ΔV 2 , the cold leakage of the sealing structure is relatively large, the condensation at the sealing structure is relatively heavy, and the heating power of the heating element is p 2 W, which can quickly remove the condensation at the heating element. When ΔV 2 ≤ ΔV < ΔV 3 , the cold leakage of the sealing structure is large, and the heating power of the heating element is p 3 W, which can quickly remove the condensation at the heating element.

[0181] For example, ΔV 1 is 1400mm 3 , ΔV 2 is 2400mm 3 , ΔV 3 is 5600mm 3 , p 1 is 10W, p 2 is 15W, p 3 is 25W.

[0182] The method provided by the embodiments of the present disclosure can determine the heating power adapted to the cold leakage situation of the sealing structure through the correlation between the offset volume and the heating power of the heating element, and can alleviate problems such as excessive heat or insufficient heat of the heating element, thereby being beneficial to improving the dew condensation removal effect on the sealing structure.

[0183] Combined with Figure 16 shown, the embodiments of the present disclosure provide another method for controlling a refrigeration device, including:

[0184] S801, the refrigeration device obtains the distance between the box ventilation opening and the unit ventilation opening.

[0186] S803. The refrigeration device determines the offset volume of the sealing structure according to the distance and offset area between the cabinet vent and the unit vent.

[0187] S804. When 0 ≤ ΔV < ΔV 1 , the adjustment scheme of the heating element is that the first heating element is turned on and the second heating element is turned off to determine the target power of the heating element as p 4 .

[0188] S805. When ΔV 1 ≤ ΔV < ΔV 2 , the adjustment scheme of the heating element is that the second heating element is turned on and the first heating element is turned off to determine the target power of the heating element as p 5 .

[0189] S806. When ΔV 2 ≤ ΔV < ΔV 3 , the adjustment scheme of the heating element is that both the first heating element and the second heating element are turned on to determine the target power of the heating element as p 6 . Wherein, ΔV 1 is the first volume threshold, ΔV 2 is the second volume threshold, ΔV 3 is the third volume threshold, ΔV 1 <ΔV 2 <ΔV 3 . p 4 <p 5 , p 6 =p 5 +p 4 .

[0190] S807. The refrigeration device controls the operation of the heating element according to the adjustment scheme of the heating element.

[0191] By switching the operation of the first heating element and the second heating element, three heating effects can be achieved: only the first heating element works, only the second heating element works, and both the first heating element and the second heating element work together, which can meet the anti-condensation requirements in a variety of different situations. In addition, with such a setting, the computer board hardware design is simple, and the heating gear can be switched only through a switch signal, which is beneficial to saving the design power of the switching power supply.
