The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Example one

Referring to fig. 4 and 5, fig. 4 and 5 are schematic structural diagrams of a gas storage device according to an exemplary embodiment of the present invention, and referring to fig. 4 and 5, the gas storage device includes:

the pipeline 101, the coil 102 and the magnetic part 103, wherein the pipeline 101 is a hollow structure, the coil 102 is wound on the pipeline 101, and the magnetic part 103 is slidably arranged in the pipeline 101 and divides the pipeline 101 into a first air storage part 1011 and a second air storage part 1012;

the first gas storage portion 1011 is communicated with the chamber to be regulated, the second gas storage portion 1012 is communicated with the outside, the coil 102 is further connected with a power supply device, and the magnetic part 103 moves in the pipeline 101 based on the size and/or direction of the electrification of the coil 102 so as to regulate the volume of the chamber to be regulated, which is communicated with the first gas storage portion 1011.

It should be noted that the technical solution provided in this embodiment is applicable to a refrigeration device with a sealing door, where the refrigeration device includes but is not limited to: refrigerator, ice chest. Taking a refrigeration device as an example of a refrigerator, a schematic view of an installation position of the gas storage device provided in this embodiment is shown in fig. 1.

It can be understood that, this embodiment provides this kind of gas storage device, according to the electromagnetic induction principle, sets up the magnetic part in the pipeline that the winding has the coil, and through the electric current method and the size that change the coil, change the position of magnetic part in the pipeline, and then adjust the volume of treating the regulation cavity that communicates with first gas storage portion, the realization is treated the change of adjusting the cavity internal pressure size, and then makes the refrigeration plant laborsaving that opens the door when frequent switch door.

In a specific practice, the magnetic member 103 may be a rubidium magnet, but is not limited thereto, and the magnetic member 103 may also be made of the rest of magnetic materials. As can be seen from fig. 1, the air storage device is vertically installed on the rear panel of the refrigerator, and according to the right-hand screw rule (i.e. ampere rule), when the coil 102 is energized, the N pole of the magnetic field generated by the coil 102 is directed either upward or downward, so that the magnetic element 103 needs to be vertically placed in the energized coil, so that the N pole of the magnetic element 103 is also upward or downward.

Referring to fig. 8, the coil is held in the right hand with the four fingers pointing in the direction of the current and the thumb pointing in the direction of the magnetic field (N pole). It can be seen that the coil 102 can generate a magnetic field (electromagnetic), where the magnetic induction B = uNI/L, 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 magnitude of 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 and the magnetic field changes accordingly. The following are exemplary:

assuming that the winding of the coil 102 is as shown in fig. 8, and the direction of the current is as the four-finger direction of the curl in fig. 8, the N pole of the magnetic field generated by the energized coil 102 points upward. Assuming that the magnetic pole direction of the magnetic member 103 is as shown in fig. 8, the upper side is S-pole and the lower side is N-pole, the magnetic member 103 will move upward according to "opposite poles attract and like poles repel".

Conversely, by controlling the direction of the current in the opposite manner to that shown in fig. 8, the S-pole of the magnetic field generated by the energized coil 102 is directed upward. Assuming that the magnetic pole direction of the magnetic member 103 is as shown in fig. 8, the upper side is S pole, and the lower side is N pole, the magnetic member 103 will move downward according to "opposite poles attract and same poles repel".

Of course, the winding manner of the coil 102 may be the opposite of that shown in fig. 8, and the current direction may also be the opposite of that shown in fig. 8, but the analysis process is consistent with the above, and will not be described again here.

It will be appreciated that when the coil 102 is energized, the coil is caused to generate a magnetic field, which is then changed by controlling the direction of the current. The generated magnetic field can generate pushing force or attraction force on the magnetic element 103 according to the 'attraction of opposite polarities and repulsion of same polarities' so as to change the motion track of the magnetic element 103.

Assuming that the refrigeration device is a refrigerator, in a specific practice, the power supply device may be a main control board of the refrigerator, the coil 102 is connected to the main control board of the refrigerator, and the main control board of the refrigerator provides current for the coil 102, and at the same time, the main control board can control the magnitude and direction of the current flowing through the coil 102.

Before a user opens a door, the main control board powers on the coil 102, so that the magnetic part 103 moves upwards, the volume of the first gas storage part 1011 can be reduced, partial gas in the first gas storage part 1011 is extruded into the cavity of the refrigerator, the pressure in the cavity can be increased, the pressure in the cavity and the external atmospheric pressure tend to be consistent, and the door of the refrigerator can be opened easily by the user. On the other hand, compare in the structure that sets up open channel in refrigerator cavity foam among the prior art, the gas storage device of this embodiment, through the separation effect of magnetic part 103, can separate cavity and external world, can avoid the problem of air conditioning leakage and condensation to can improve the refrigeration effect of refrigerator and reduce the energy consumption of refrigerator, still can improve user's use and experience. The gas storage device of the embodiment solves the technical problems that in the prior art, the refrigerator enables the pressure in the cavity to be consistent with the external atmospheric pressure through the open channel, and cold air leakage and condensation exist.

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 within the pipe 101, as shown in fig. 5 and 6. Preferably, the magnetic member 103 has a cylindrical shape. The height of the magnetic member 103 may not be limited. According to the gas storage device of the preferred technical scheme of the embodiment, the cross-sectional area of the magnetic part 103 is equal to the cross-sectional area of the cavity in the pipeline 101, so that the first gas storage part 1011 and the second gas storage part 1012 can be completely separated by the magnetic part 103, and the problems that the refrigeration effect and the energy consumption of the refrigerator are influenced by cold gas leakage and the user experience is influenced by condensation caused by mutual ventilation of the first gas storage part 1011 and the second gas storage part 1012 at the upper end and the lower end of the magnetic part 103 are avoided.

According to a preferred embodiment, when the magnetic member 103 moves toward the direction close to the chamber to be conditioned, the volume of the first gas storage 1011 decreases and the pressure in the chamber to be conditioned increases; when the magnetic member 103 moves away from the chamber to be conditioned, the volume of the first gas storage 1011 increases and the pressure in the chamber to be conditioned decreases. According to the gas storage device in the preferred technical scheme of the embodiment, when the volume of the pipeline 101 is fixed, when the magnetic part 103 moves towards the direction close to the chamber to be regulated, the volume of the first gas storage part 1011 is reduced, so that part of gas in the first gas storage part 1011 can be extruded into the chamber of the refrigerator, the pressure in the chamber can be increased, the pressure in the chamber tends to be consistent with the external atmospheric pressure, and the door of the refrigerator can be easily opened by a user; meanwhile, the volume of the second gas storage portion 1012 is increased, and since the second gas storage portion 1012 is communicated with the outside, the outside gas can enter the second gas storage portion 1012, so that the pressure inside the second gas storage portion 1012 tends to be consistent with the outside atmospheric pressure. Similarly, when the magnetic component 103 moves towards the direction away from the chamber to be regulated, the volume of the first air storage portion 1011 increases, so that part of air in the chamber of the refrigerator can enter the first air storage portion 1011, the pressure in the chamber can be reduced, the chamber can be kept in a low-pressure state (specifically, lower than atmospheric pressure), and the fresh-keeping effect of the refrigerator can be improved.

According to a preferred embodiment, when the coil 102 is energized to generate a magnetic field, B = uNI/L, the magnetic member 103 is moved within the pipe 101 by changing the direction of the magnetic field by controlling the direction of the current in the coil 102.

Assuming that the winding of the coil 102 is as shown in fig. 8, and the direction of the current is as the four-finger direction of the curl in fig. 8, the N pole of the magnetic field generated by the energized coil 102 points upward. Assuming that the magnetic pole direction of the magnetic member 103 is as shown in fig. 8, the upper side is S pole, and the lower side is N pole, the magnetic member 103 moves toward the chamber to be regulated according to "opposite attraction and like repulsion". And then can increase the pressure in the strong room, make the user easily open the door.

Conversely, if the direction of the current is controlled in the opposite manner to that shown in fig. 8, the S-pole of the magnetic field generated by the energized coil 102 is directed upward. Assuming that the magnetic poles of the magnetic member 103 are oriented as shown in fig. 8, with the upper S pole and the lower N pole, the magnetic member 103 will move away from the chamber to be conditioned according to the "attraction between opposite poles and repulsion between like poles". Further, the pressure in the cavity can be reduced, and the fresh-keeping effect of the refrigerator can be improved.

It will be appreciated that when the coil 102 is energized, the coil is caused to generate a magnetic field, which is then changed by controlling the direction of the current. The generated magnetic field can generate thrust or attraction force on the magnetic element 103 according to 'attraction between opposite poles and repulsion between like poles' so as to change the motion track of the magnetic element 103.

According to a preferred embodiment, the gas storage device further comprises a first fixing member 104, the first fixing member 104 is disposed below the magnetic member 103, and the first fixing member 104 is further located at a corner of the pipe 101, so that 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. 6. Preferably, the first fixing member 104 is a fixing pin, and the fixing pin is transversely disposed at a corner of the pipe 101. According to the gas storage device in the preferred technical scheme of the embodiment, the magnetic part 103 can be prevented from falling to the corner of the pipeline 101 under the blocking effect of the first fixing part 104, so that the problem that the magnetic part 103 is clamped and cannot move upwards is solved, and the reliability that the magnetic part 103 moves up and down in the pipeline 101 is ensured.

Referring to fig. 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, as shown in fig. 1 and 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 is interference-fitted with the pipe 101, as shown in fig. 7. Preferably, the to-be-installed part is, for example, a lower bottom plate 201 of a refrigerator. More preferably, the second fixing member 105 is disposed below the lower base plate 201, and the lower base plate 201 is also provided with a through hole for installing the active pipe 101. The gas storage device of the preferred technical scheme of this embodiment, through second mounting 105 with pipeline 101 be fixed in the department of waiting to install the department, not only can realize pipeline 101 fixed, still can avoid waiting to install the intensity of department and receive the influence to guarantee the reliability of refrigerator.

Example two

A refrigeration unit with a sealing door according to an exemplary embodiment of the present invention is shown, comprising:

the controller, the chamber and the gas storage device are arranged in the cavity;

a first gas storage part (1011) of the gas storage device is communicated with the cavity, a second gas storage part (1012) of the gas storage device is communicated with the outside, and a coil of the gas storage device is connected with the controller.

In particular practice, the refrigeration equipment includes, but is not limited to: refrigerators and freezers. Taking a refrigeration device as an example of a refrigerator, the installation position of the gas storage device provided in this embodiment is schematically shown in fig. 1.

It can be understood that, according to the technical scheme provided by this embodiment, by setting the gas storage device in the refrigeration device, the volume inside the refrigeration device is adjustable, and then people are determined within the preset range around the refrigeration device, and the possibility that the refrigeration device is opened at the current time is predicted according to the historical experience value (the interval time between the current time and the last time when the refrigeration device is closed is not greater than the preset time), the gas storage device is controlled to be opened, so as 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 refrigeration device is ready to be opened at any time, and thus when a user opens the refrigeration device, the user does not feel hard because the internal and external pressures of the refrigeration device are balanced, and the user experience is greatly improved.

EXAMPLE III

Referring to fig. 9, fig. 9 is a flowchart illustrating a control method of a refrigeration apparatus according to an exemplary embodiment of the present invention, referring to fig. 9, the method including:

s11, detecting whether people exist in a preset range around the refrigeration equipment at the current moment;

s12, if people are judged to be in a preset range around the refrigeration equipment and the interval time between the current moment and the last door closing moment of the refrigeration equipment is not more than the preset time, controlling the gas storage device to be opened and controlling the gas storage device to compress the volume inside the refrigeration equipment so as to improve the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure;

It should be noted that, in a specific practice, the technical solution provided in this embodiment needs to be loaded in a controller of the refrigeration equipment to operate, or, loaded in an electronic device connected to the controller of the refrigeration equipment to operate. The refrigeration equipment includes but is not limited to: refrigerators and freezers. Taking a refrigeration device as an example of a refrigerator, the installation position of the gas storage device provided in this embodiment is schematically shown in fig. 1.

It is understood that the preset time period is set according to the time interval data of the historical opening and closing of the door of the refrigeration equipment under the condition of a person, for example, the preset time period is set according to the average value of the time intervals of the historical opening and closing of the door, or the minimum value of the time intervals of the historical opening and closing of the door is taken as the preset time period.

The advantage of setting up like this lies in, if the interval duration of present moment apart from the last refrigeration plant moment of closing the door is not more than the length of predetermineeing, just explains according to user's historical use habit, and although the user still can not open the door at present moment, the user just has the possibility of opening the door at any time in refrigeration plant's the preset range around. At the moment, the gas storage device needs to be controlled to be opened, and the gas storage device is controlled to compress the volume inside the refrigeration equipment so as to improve the pressure inside the refrigeration equipment until the pressure inside the refrigeration equipment is equal to the external atmospheric pressure, so that the preparation is made at any time for a user to open the door in a labor-saving manner.

In a 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 comprises: the door opening time, the door closing time and the detected time of the person are measured at each time;

For example, the following door opening and closing time information is recorded in the following event occurrence sequence, including:

1. recording the first door opening time of the refrigeration equipment: t0;

2. recording the first door closing time of the refrigeration equipment: t1;

3. recording the existence of people outside the detection door of the refrigeration equipment: t2;

4. recording the door opening time of the refrigeration equipment: t3;

5. recording the door closing time of the refrigeration equipment: t4;

6. recording the existence of people outside the detection door of the refrigeration equipment: t5;

7. recording the door opening time of the refrigeration equipment: t6;

.........

the time interval Δ T1= T3-T1, Δ T2= T6-T4, for opening and closing the door, is calculated.

Assuming that the preset time duration is T0, T0 may be set as an average value of Δ T1, Δ T2,.. Or a minimum value of Δ T1, Δ T2,.. Once.

In the technical solution provided in this embodiment of actual operation, further taking the recorded door opening and closing time information as an example, in step S12, "if it is determined that people are in the preset range around the refrigeration equipment and the interval duration between the current time and the last door closing time of the refrigeration equipment is not greater than the preset duration, the gas storage device is controlled to be opened", specifically:

assuming that the current time is T2, according to the technical scheme provided by the embodiment, the gas storage device is controlled to be opened, and T0 is required to be satisfied when T2-T1 is less than or equal to T0, so that preparation is made for opening the door at T3;

assuming that the current time is T5, according to the technical scheme provided by the embodiment, the gas storage device is controlled to be opened, and T0 is required to be equal to or less than T5-T4, so that preparation is made for opening the door at the time of T6;

.........

i.e. satisfies t _3n+2 -t _3n+1 And when the value is less than or equal to T0 and n is greater than or equal to 0, controlling the gas storage device to be opened.

It can be understood that, after the gas storage device is started, according to the record in step S12, "control the gas storage device to compress the volume inside the refrigeration apparatus, so as to increase the pressure inside the refrigeration apparatus, until the pressure inside the refrigeration apparatus is equal to the external atmospheric pressure," at this time, the gas storage device starts to compress once, so as to reduce the volume inside the refrigeration apparatus. 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 the constant 8.31J/mol, T is the thermodynamic temperature of the gas inside the refrigeration equipment, and the right of the equation is a constant value. When V is reduced, the pressure P inside the refrigeration equipment is increased, and the pressure difference between the inside and the outside of the refrigeration equipment is rapidly balanced until the pressure difference delta P = P-P0=0, wherein P0 is the atmospheric pressure outside the refrigeration equipment, and is usually a standard atmospheric pressure; the value of P is obtained through setting up the inside atmospheric pressure monitor of refrigeration plant, also is known quantity.

In specific practice, in step S11, "detect the current time, whether someone is in the preset range around the refrigeration equipment", specifically:

detecting the distance from the human body to the refrigeration equipment through a human body infrared scanning device;

The threshold value is set according to a historical empirical value, or according to experimental data, or according to a user's need, for example, the threshold value is set to 1m.

The human body infrared scanning device can be a human body infrared sensor additionally arranged above the refrigerating device, and can also be a human body infrared sensor carried by the refrigerating device.

Further, if it is determined that no person is present within the preset range around the refrigeration equipment, or,

and if the situation that people exist in the preset range around the refrigeration equipment is judged, and the interval time from the current time to the last door closing time of the refrigeration equipment is longer than the preset time, the gas storage device is not started.

It can be understood that if no person is in the preset range around the refrigeration equipment, the possibility that the refrigeration equipment opens the door is not available, so that the gas storage device can be directly controlled not to be started.

If people exist in the preset range around the refrigeration equipment, but the interval time from the current time to the last time of closing the door of the refrigeration equipment is longer than the preset time, the situation that a user possibly stays around the refrigeration equipment only, does not want to open the refrigeration equipment, and does not have the possibility of opening the door is solved, so that the gas storage device can be directly controlled not to be started.

It can be understood that the control method of the refrigeration apparatus provided by this embodiment has higher control accuracy, reduces control errors, and can improve user experience by combining and applying multiple determination conditions.

Further, after the gas storage device is started, if any of the following reset conditions is met, the gas storage device is controlled to reset, wherein the reset conditions comprise that:

at the present moment, the refrigeration equipment is in a door opening state.

It should be noted that, the term "reset" in this embodiment means that the magnetic member 103 in the air storage device illustrated in fig. 4 and 5 moves to the position initially set by the system, i.e. the initial position.

It can be understood that, in the technical solution provided in this embodiment, the refrigeration device is controlled to prepare for opening the door according to the historical usage habit of the user, but the actual situation is certainly not exactly the same as the historical usage habit of the user, so there may be a case of erroneous judgment. For example, according to the technical scheme provided by this embodiment, the gas storage device is turned on, the refrigeration equipment is ready to open the door, but the user leaves from the preset range around the refrigeration equipment, which means that the user does not need to open the door at present, so that the gas storage device can be directly controlled to reset to prepare for opening and closing the door next time, thereby saving energy consumption.

In specific practice, after the gas storage device is opened, a user really opens the door, and at this time, after the door is opened, the gas storage device does not need to be controlled to continue to compress the volume inside the refrigeration equipment, so that the gas storage device can be directly controlled to reset, preparation is made for opening and closing the door next time, and energy consumption is saved.

step S22, if the distance is smaller than or equal to the threshold value, determining that people exist in the preset range around the refrigeration equipment, and skipping to step S23, otherwise, determining that no people exist in the preset range around the refrigeration equipment, and ending the determination process;

step S23, judging whether t is satisfied _3n+2 -t _3n+1 T0 is less than or equal to, if yes, jumping to the step S24, otherwise, judging that the flow is ended;

step S24, judging whether P-P0=0 is met, if so, jumping to step S26, otherwise, jumping to step S25;

s25, controlling the gas storage device to be opened, controlling the gas storage device to compress the volume inside the refrigeration equipment so as to improve the pressure inside the refrigeration equipment until P-P0=0, and jumping to S26;

s26, judging that the current refrigeration equipment can be opened easily, and controlling the air storage device to reset;

the preset time T0 is set according to time interval data of historical door opening and closing of the refrigeration equipment under the condition of people.
