Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and in particular to a gas storage device, refrigeration equipment and a control method, and electronic equipment. Background Art

[0002] As people's living standards improve, the demand for refrigeration equipment is increasing, and the capacity of refrigeration equipment is also gradually increasing. The capacity of refrigeration equipment has increased from tens of liters in the past to hundreds of liters today. As the capacity becomes larger, the variety of food stored in refrigeration equipment has increased, and users have also used refrigeration equipment more frequently.

[0003] Traditional refrigeration equipment, such as refrigerators, has door seals on the doors to ensure the sealing of the refrigerator chamber. However, if the user frequently opens and closes the door during use, the instantaneous negative pressure caused by frequent opening and closing of the door will make it more difficult for the user to open the door, resulting in the problem of difficulty in opening the door. The specific reason is that the door seal has a certain degree of deformation capacity. At the moment of closing the door, the door squeezes the seal, and at the same time, some of the air in the chamber is squeezed out, causing the pressure in the chamber to decrease. Since the pressure in the chamber is lower than the external atmospheric pressure, it makes it difficult to open the door. If the door is opened frequently, the air entering the refrigerator will contract when it is cold, which will also increase the negative pressure in the chamber and make it difficult to open the door. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a gas storage device, a refrigeration device and a control method, and an electronic device to solve the problem in the prior art that the frequent opening and closing of the refrigeration device door and the instantaneous negative pressure caused by the frequent opening and closing of the door make it more difficult for the user to open the door.

[0008] Furthermore, the shape of the magnetic member matches the shape of the pipeline, and the cross-sectional area of ​​the magnetic member is the same as the cross-sectional area of ​​the pipeline.

[0009] Furthermore, when the magnetic part moves toward the direction approaching the chamber to be adjusted, the volume of the first air storage part decreases, and the pressure in the chamber to be adjusted increases; when the magnetic part moves toward the direction away from the chamber to be adjusted, the volume of the first air storage part increases, and the pressure in the chamber to be adjusted decreases.

[0010] Furthermore, when the coil (102) is energized to generate a magnetic field, the magnetic induction intensity B=uNI / L, and the direction of the magnetic field is changed by controlling the direction of the current in the coil (102) to cause the magnetic member (103) to move within the pipe (101).

[0024] If it is determined that there is a person within a preset range around the refrigeration equipment, and the time interval between the current moment and the last time the refrigeration equipment door was closed is not greater than the preset time, the gas storage device is controlled to open and the gas storage device is controlled to compress the volume inside the refrigeration equipment to increase the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure;

[0025] The preset duration is set according to the historical time interval data of the door opening and closing of the refrigeration equipment when there are people present.

[0026] Furthermore, if it is determined that there is no one within the preset range around the refrigeration equipment, or if it is determined that there is someone within the preset range around the refrigeration equipment, but the interval between the current moment and the last time the refrigeration equipment was closed is greater than the preset time, the gas storage device will not be started.

[0040] By setting an air storage device in the refrigeration equipment, the volume inside the refrigeration equipment can be adjusted. Then, when it is determined that there is someone within a preset range around the refrigeration equipment and it is predicted based on historical experience that the refrigeration equipment may be opened at the current moment (the interval between the current moment and the last time the refrigeration equipment was closed is not greater than the preset time), the air storage device is controlled to open to increase the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure, so that the refrigeration equipment is ready to be opened at any time.

[0056] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0057] Example 1

[0058] See also Figure 4 and Figure 5 , Figure 4 and Figure 5 This is a schematic diagram of the structure of a gas storage device according to an exemplary embodiment of the present invention, see Figure 4 and Figure 5 , the gas storage device comprises:

[0059] Pipe 101, coil 102 and magnetic member 103, wherein pipe 101 is a hollow structure, coil 102 is wound around pipe 101, and magnetic member 103 is slidably disposed in pipe 101 and divides pipe 101 into a first gas storage portion 1011 and a second gas storage portion 1012;

[0060] The first gas storage part 1011 is connected to the chamber to be adjusted, the second gas storage part 1012 is connected to the outside world, and the coil 102 is also connected to a power supply device. The magnetic part 103 moves in the pipe 101 based on the size and / or direction of the power supply to the coil 102 to adjust the volume of the chamber to be adjusted connected to the first gas storage part 1011.

[0061] It should be noted that the technical solution provided in this embodiment is applicable to refrigeration equipment with sealed doors, including but not limited to refrigerators and freezers. Taking the refrigerator as an example, the installation position diagram of the gas storage device provided in this embodiment is as follows: Figure 1 shown.

[0062] It can be understood that this embodiment provides such an air storage device. According to the principle of electromagnetic induction, a magnetic part is arranged in a pipe wrapped with a coil. By changing the current method and size of the coil, the position of the magnetic part in the pipe is changed, and then the volume of the chamber to be adjusted connected to the first air storage part is adjusted, thereby realizing a change in the pressure in the chamber to be adjusted, thereby making it easier to open the door of the refrigeration equipment when the door is opened and closed frequently.

[0063] In specific practice, the magnetic member 103 may be a neodymium magnet, but is not limited thereto. The magnetic member 103 may also be made of other magnetic materials. Figure 1 As can be seen from the figure, the gas storage device is installed vertically on the back panel of the refrigerator. According to the right-hand screw rule (i.e., Ampere's law), when the coil 102 is energized, the north pole of the magnetic field generated by the coil 102 points either upward or downward. Therefore, the magnetic member 103 needs to be placed vertically in the energized coil so that the north pole of the magnetic member 103 is also upward or downward.

[0064] See also Figure 8 , hold the coil in your right hand with your four fingers pointing in the direction of the current. The direction pointed by your thumb is the direction of the magnetic field (N pole). Thus, the energized coil 102 can generate a magnetic field (electromagnetism), where the magnetic induction intensity B = uNI / L, where N is the total number of turns of the coil 102, L is the length of the coil 102, u is a constant, and I is the current in the coil 102. It can be seen that the direction of the magnetic field is related to the direction of the current. Changing the direction of the current will change the magnetic field accordingly. For example:

[0065] Assume that the winding method of the coil 102 is as follows Figure 8 As shown, the direction of current is Figure 8If the four fingers of the coil are curled in the middle, the N pole of the magnetic field generated by the coil 102 after power is applied points upward. Figure 8 As shown, the upper side is the S pole and the lower side is the N pole. According to the principle of “opposites attract and likes repel”, the magnetic member 103 will move upward.

[0066] On the contrary, by controlling the direction of the current Figure 8 The opposite is true, so the S pole of the magnetic field generated by the coil 102 after power is applied points upwards. Figure 8 As shown, the upper side is the S pole and the lower side is the N pole. According to the principle of “opposites attract and likes repel”, the magnetic member 103 will move downward.

[0067] Of course, the winding method of the coil 102 can be different from Figure 8 The current direction can also be opposite to the way shown. Figure 8 The method shown is opposite, but the analysis process is the same as above and will not be repeated here.

[0068] It is understood that when coil 102 is energized, it generates a magnetic field, and the direction of the magnetic field can be changed by controlling the direction of the current. The generated magnetic field can generate a thrust or attraction on magnetic element 103 according to the principle of "opposites attract, likes repel", thereby changing the motion trajectory of magnetic element 103.

[0069] Assuming that the refrigeration device is a refrigerator, in actual practice, the power supply device can be the main control board of the refrigerator. The coil 102 is connected to the main control board of the refrigerator, and current is provided to the coil 102 through the main control board of the refrigerator. At the same time, the magnitude and direction of the current flowing through the coil 102 can also be controlled by the main control board.

[0070] Before the user opens the door, the main control board energizes coil 102, causing magnetic element 103 to move upward, thereby reducing the volume of first gas storage section 1011. Some of the gas within first gas storage section 1011 is squeezed into the refrigerator chamber, thereby increasing the pressure within the chamber and aligning it with the external atmospheric pressure, allowing the user to easily open the door. On the other hand, compared to the prior art structure of providing an open channel within the refrigerator chamber foam, the gas storage device of this embodiment, through the separating effect of magnetic element 103, can separate the chamber from the outside world, thereby preventing the problems of cold air leakage and condensation, thereby improving the refrigerator's cooling effect, reducing the refrigerator's energy consumption, and enhancing the user experience. In other words, the gas storage device of this embodiment solves the technical problem of prior art refrigerators using open channels to align the pressure within the chamber with the external atmospheric pressure, which can cause cold air leakage and condensation.

[0071] According to a preferred embodiment, the shape of the magnetic member 103 matches the shape of the pipe 101, and the cross-sectional area of ​​the magnetic member 103 is equal to the cross-sectional area of ​​the cavity in the pipe 101. Figure 5 and Figure 6 As shown. Preferably, the magnetic member 103 is cylindrical. The height of the magnetic member 103 may not be restricted. In the gas storage device of the preferred technical solution of this embodiment, the cross-sectional area of ​​the magnetic member 103 is equal to the cross-sectional area of ​​the cavity in the pipe 101, so that the first gas storage part 1011 and the second gas storage part 1012 can be completely separated by the magnetic member 103, avoiding the first gas storage part 1011 and the second gas storage part 1012 at the upper and lower ends of the magnetic member 103 from ventilating each other, resulting in cold air leakage affecting the refrigeration effect and energy consumption of the refrigerator and generating condensation affecting the user experience.

[0072] According to a preferred embodiment, when the magnetic member 103 moves toward the direction approaching the chamber to be adjusted, the volume of the first air storage portion 1011 decreases, and the pressure in the chamber to be adjusted increases; when the magnetic member 103 moves toward the direction away from the chamber to be adjusted, the volume of the first air storage portion 1011 increases, and the pressure in the chamber to be adjusted decreases. In the gas storage device of the preferred technical solution of this embodiment, when the volume of the pipeline 101 is fixed, when the magnetic part 103 moves toward the direction close to the chamber to be adjusted, the volume of the first gas storage part 1011 is reduced, so that part of the gas in the first gas storage part 1011 is squeezed into the refrigerator chamber, thereby increasing the pressure in the chamber, making the pressure in the chamber tend to be consistent with the external atmospheric pressure, and thus making it easy for the user to open the door; at the same time, the volume of the second gas storage part 1012 is increased, and since the second gas storage part 1012 is connected to the outside world, external gas can enter the second gas storage part 1012, so that the pressure in the second gas storage part 1012 tends to be consistent with the external atmospheric pressure. Similarly, when the magnetic part 103 moves away from the chamber to be adjusted, the volume of the first air storage part 1011 increases, so that part of the gas in the refrigerator chamber can enter the first air storage part 1011, thereby reducing the pressure in the chamber and maintaining a low pressure state in the chamber (specifically below atmospheric pressure), which can improve the preservation effect of the refrigerator.

[0073] According to a preferred embodiment, when the coil 102 is energized to generate a magnetic field, the magnetic induction intensity B=uNI / L, and the direction of the magnetic field is changed by controlling the direction of the current in the coil 102 to move the magnetic member 103 in the pipe 101.

[0074] Assume that the winding method of the coil 102 is as follows Figure 8 As shown, the direction of current is Figure 8 If the four fingers of the coil are curled in the middle, the N pole of the magnetic field generated by the coil 102 after power is applied points upward. Figure 8As shown, the upper part is the S pole and the lower part is the N pole. According to the principle of "opposites attract and likes repel", the magnetic member 103 moves toward the chamber to be adjusted, thereby increasing the pressure in the chamber and making it easier for the user to open the door.

[0075] On the contrary, if the current direction is controlled by Figure 8 The opposite is true, so the S pole of the magnetic field generated by the coil 102 after power is applied points upwards. Figure 8 As shown, the upper pole is the S pole and the lower pole is the N pole. According to the principle of "opposites attract, likes repel", the magnetic member 103 will move away from the chamber to be adjusted. This can reduce the pressure in the chamber and improve the refrigerator's preservation effect.

[0076] It is understood that when coil 102 is energized, it generates a magnetic field, and the direction of the magnetic field can be changed by controlling the direction of the current. The generated magnetic field can generate a thrust or attraction on magnetic element 103 according to the principle of "opposites attract, likes repel", thereby changing the motion trajectory of magnetic element 103.

[0077] According to a preferred embodiment, the gas storage device further includes a first fixing member 104, which is disposed below the magnetic member 103 and is also located at the corner of the pipe 101, and the cross-sectional area of ​​the corner of the pipe 101 is smaller than the cross-sectional area of ​​the magnetic member 103, as shown in FIG. Figure 6 As shown. Preferably, the first fixing member 104 is a fixing pin, which is horizontally arranged at the corner of the pipe 101. The gas storage device of the preferred technical solution of this embodiment can prevent the magnetic member 103 from falling to the corner of the pipe 101 through the blocking effect of the first fixing member 104, thereby preventing the magnetic member 103 from getting stuck and unable to move upward, thereby ensuring the reliability of the magnetic member 103 moving up and down in the pipe 101.

[0078] See also Figure 1 According to a preferred embodiment, the gas storage device further includes a second fixing member 105, the second fixing member 105 is fixedly connected to the portion to be installed, and the pipeline 101 is fixedly connected to the second fixing member 105, such as Figure 1 and Figure 3 Preferably, the second fixing member 105 has a through hole 1051, the pipe 101 is installed in the through hole 1051, and the through hole 1051 and the pipe 101 are interference fit, as shown. Figure 7As shown. Preferably, the portion to be mounted is, for example, the lower base plate 201 of the refrigerator. More preferably, the second fixing member 105 is disposed below the lower base plate 201, which also includes a through hole for mounting the active pipe 101. In the preferred technical solution of this embodiment, the gas storage device secures the pipe 101 to the portion to be mounted via the second fixing member 105. This not only secures the pipe 101 but also prevents any loss of strength at the portion to be mounted, thereby ensuring the reliability of the refrigerator.

[0079] Example 2

[0080] According to an exemplary embodiment of the present invention, a refrigeration device with a sealed door includes:

[0081] Controller, chamber, and the aforementioned gas storage device;

[0082] The first gas storage part (1011) of the gas storage device is in communication with the chamber, the second gas storage part (1012) of the gas storage device is in communication with the outside, and the coil of the gas storage device is connected to the controller.

[0083] In specific practice, the refrigeration equipment includes but is not limited to: refrigerators and freezers. Taking the refrigeration equipment as an example, the installation position diagram of the gas storage device provided in this embodiment is as follows: Figure 1 shown.

[0084] It can be understood that the technical solution provided by this embodiment is to set an air storage device in the refrigeration equipment so that the volume inside the refrigeration equipment can be adjusted. Then, when it is determined that there is someone within a preset range around the refrigeration equipment and it is predicted based on historical experience that the refrigeration equipment may be opened at the current moment (the interval between the current moment and the last time the refrigeration equipment was closed is not greater than the preset time), the air storage device is controlled to open to increase the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure, so that the refrigeration equipment is ready to be opened at any time. This makes it possible for the user to open the refrigeration equipment without feeling any effort when opening the refrigeration equipment due to the balanced pressure inside and outside the refrigeration equipment, which greatly improves the user experience.

[0085] Example 3

[0086] See also Figure 9 , Figure 9 is a flow chart showing a method for controlling a refrigeration device according to an exemplary embodiment of the present invention. Figure 9 , the method comprising:

[0087] Step S11: Detect whether there is anyone within a preset range around the refrigeration equipment at the current moment;

[0088] Step S12: If it is determined that there is a person within the preset range around the refrigeration equipment, and the time interval between the current moment and the last time the refrigeration equipment door was closed is not greater than the preset time, the gas storage device is controlled to open and the gas storage device is controlled to compress the volume inside the refrigeration equipment to increase the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure;

[0089] The preset duration is set according to the historical time interval data of the door opening and closing of the refrigeration equipment when there are people present.

[0090] It should be noted that the technical solution provided in this embodiment needs to be loaded into the controller of the refrigeration equipment for operation, or loaded into the electronic device connected to the controller of the refrigeration equipment for operation. The refrigeration equipment includes but is not limited to: refrigerators and freezers. Taking the refrigeration equipment as an example, the installation position diagram of the gas storage device provided in this embodiment is as follows: Figure 1 shown.

[0091] It can be understood that the preset duration is set based on the historical time interval data of opening and closing the door of the refrigeration equipment when there are people. For example, it is set based on the average value of the historical time intervals of opening and closing the door, or the minimum value of the historical time intervals of opening and closing the door is taken as the preset duration.

[0092] The advantage of this setting is that if the interval between the current moment and the last time the refrigeration device closed is no longer than the preset time, it means that according to the user's historical usage habits, although the user will not open the door at the current moment, the user is within the preset range around the refrigeration device and may open the door at any time. At this time, it is necessary to control the gas storage device to open and control the gas storage device to compress the volume inside the refrigeration device to increase the pressure inside the refrigeration device until the pressure inside the refrigeration device is equal to the external atmospheric pressure, so that the user can open the door at any time without effort.

[0093] In specific practice, the door opening and closing time information of the refrigeration equipment can be recorded, and the door opening and closing time information at least includes: each door opening time, each door closing time, and each time a person is detected;

[0094] The preset duration is set according to the door opening and closing time information.

[0095] For example, the following door opening and closing time information is recorded in the order of the following events:

[0096] 1. Record the time when the refrigeration equipment door is first opened: t0;

[0097] 2. Record the time when the refrigeration equipment is first closed: t1;

[0098] 3. Record that there is someone outside the refrigeration equipment detection door: t2;

[0099] 4. Record the time when the refrigeration equipment door is opened: t3;

[0100] 5. Record the time when the refrigeration equipment closes: t4;

[0101] 6. Record that there is someone outside the refrigeration equipment detection door: t5;

[0102] 7. Record the time when the refrigeration equipment door is opened: t6; .........

[0104] Calculate the time intervals between opening and closing the door: △T1 = t3 - t1, △T2 = t6 - t4, ...

[0105] Assuming that the preset time length is T0, then T0 can be set to the average value of ΔT1, ΔT2, ..., or the minimum value of ΔT1, ΔT2, ... is taken.

[0106] In the actual operation of the technical solution provided by this embodiment, taking the above-mentioned recorded door opening and closing time information as an example, in step S12, "if it is determined that there is a person within the preset range around the refrigeration device, and the interval between the current time and the last time the refrigeration device closed the door is not greater than the preset time, then controlling the gas storage device to open" is specifically as follows:

[0107] Assuming that the current time is t2, according to the technical solution provided in this embodiment, the control of the gas storage device to open needs to meet t2-t1≤T0, so as to prepare for the door opening at time t3;

[0108] Assuming that the current time is t5, according to the technical solution provided in this embodiment, the control of the gas storage device to open needs to meet t5-t4≤T0, so as to prepare for the door opening at time t6; .........

[0110] That is, satisfying t 3n+2 -t 3n+1 When ≤T0 and n≥0, the gas storage device is controlled to open.

[0111] It is understandable that after the gas storage device is started, according to the record of step S12 "controlling the gas storage device to compress the volume inside the refrigeration equipment to increase the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure", at this time, the gas storage device begins a compression to reduce the volume inside the refrigeration equipment. According to the ideal gas state equation PV=nRT, where P is the pressure inside the refrigeration equipment, V is the volume inside the refrigeration equipment, n is the number of moles, R is a constant of 8.31 J / mol, T is the thermodynamic temperature of the gas inside the refrigeration equipment, and the right side of the equation is a constant. When V decreases, the pressure P inside the refrigeration equipment increases, quickly balancing the pressure difference between the inside and outside of the refrigeration equipment until the pressure difference ΔP=P-P0=0, where P0 is the atmospheric pressure outside the refrigeration equipment, usually one standard atmospheric pressure; the value of P is obtained through the air pressure monitor installed inside the refrigeration equipment and is also a known quantity.

[0112] It can be understood that the technical solution provided by this embodiment is to set an air storage device in the refrigeration equipment so that the volume inside the refrigeration equipment can be adjusted. Then, when it is determined that there is someone within a preset range around the refrigeration equipment and it is predicted based on historical experience that the refrigeration equipment may be opened at the current moment (the interval between the current moment and the last time the refrigeration equipment was closed is not greater than the preset time), the air storage device is controlled to open to increase the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure, so that the refrigeration equipment is ready to be opened at any time. This makes it possible for the user to open the refrigeration equipment without feeling any effort when opening the refrigeration equipment due to the balanced pressure inside and outside the refrigeration equipment, which greatly improves the user experience.

[0113] In practice, the process of "detecting whether there is anyone within a preset range around the refrigeration equipment at the current moment" in step S11 is as follows:

[0114] Detect the distance between the human body and the refrigeration equipment through the human body infrared scanning device;

[0115] If the distance is less than or equal to the threshold, it is determined that there is a person within the preset range around the refrigeration device; otherwise, it is determined that there is no person within the preset range around the refrigeration device.

[0116] It should be noted that the threshold is set according to historical experience values, or according to experimental data, or according to user needs. For example, the threshold is set to 1m.

[0117] The human infrared scanning device may be a human infrared sensor installed above the refrigeration device, or may be a human infrared sensor built into the refrigeration device.

[0118] Furthermore, if it is determined that there is no one within the preset range around the refrigeration equipment, or,

[0119] If it is determined that there is someone within the preset range around the refrigeration equipment, but the interval between the current moment and the last time the refrigeration equipment was closed is greater than the preset time, the gas storage device will not be started.

[0120] It is understandable that if there is no one within the preset range around the refrigeration equipment, it means that the refrigeration equipment cannot open the door, so the gas storage device can be directly controlled not to start.

[0121] If there is someone within the preset range around the refrigeration equipment, but the interval between the current moment and the last time the refrigeration equipment door was closed is greater than the preset time, it means that the user may just be staying around the refrigeration equipment and does not want to turn on the refrigeration equipment, and there is no possibility of opening the door, so the gas storage device can be directly controlled not to start.

[0122] It can be understood that the combined use of multiple judgment conditions can make the control method of the refrigeration equipment provided by this embodiment more accurate, reduce control errors, and improve user experience.

[0123] Furthermore, after the gas storage device is turned on, if any of the following reset conditions is met, the gas storage device is controlled to reset, and the reset conditions include:

[0124] At this moment, there is no one within the preset range around the refrigeration equipment, or,

[0125] At this moment, the refrigeration equipment is in the open state.

[0126] It should be noted that the “reset” mentioned in this embodiment refers to Figure 4 and Figure 5 The magnetic member 103 in the illustrated gas storage device moves to a position initially set by the system, ie, an initial position.

[0127] It is understandable that the technical solution provided in this embodiment controls the refrigeration device to prepare for door opening based on the user's historical usage habits. However, actual conditions will certainly not be identical to the user's historical usage habits, so misjudgment may occur. For example, according to the technical solution provided in this embodiment, the gas storage device is activated and the refrigeration device is ready to open the door, but the user leaves the preset range around the refrigeration device. This indicates that the user does not need to open the door at this time, so the gas storage device can be directly controlled to reset in preparation for the next door opening, thereby saving energy.

[0128] In actual practice, after the gas storage device is turned on, the user does open the door. At this time, since the door has been opened, there is no need to control the gas storage device to continue compressing the volume inside the refrigeration equipment. Therefore, the gas storage device can also be directly controlled to reset and prepare for the next door opening and closing to save energy.

[0129] See also Figure 10 , Figure 10 is an operational flow chart of a control method for a refrigeration device according to another exemplary embodiment of the present invention, see Figure 10 , the method comprising:

[0130] Step S21: Detecting the distance between the human body and the refrigeration equipment by using a human infrared scanning device;

[0131] Step S22: If the distance is less than or equal to the threshold, it is determined that there is a person within the preset range around the refrigeration device, and the process jumps to step S23; otherwise, it is determined that there is no person within the preset range around the refrigeration device, and the determination process ends;

[0132] Step S23: Determine whether t 3n+2 -t 3n+1 ≤T0, if so, jump to step S24, otherwise, the determination process ends;

[0133] Step S24: determine whether P-P0=0 is satisfied. If so, jump to step S26; otherwise, jump to step S25.

[0134] Step S25: Control the gas storage device to open and compress the volume inside the refrigeration device to increase the pressure inside the refrigeration device until P-P0=0, and then jump to step S26;

[0135] Step S26: Determine whether the door of the current refrigeration equipment can be opened easily, and control the gas storage device to reset;

[0136] The preset time duration T0 is set according to the historical time interval data of the door opening and closing of the refrigeration equipment when there are people.
